Obs & gynae Flashcards

Question

What are the two types or urinary incontinence?

Answer 1

--> urge incontinence --> Stress incontinence identifying which one determines the management

Answer 2

overactivtiy of the detrusor muscle of the bladder --> also known as overactive bladder

Answer 3

--> Suddenly feeling the urge to pass urine --> rushing to the bathroom and not arriving before urination occurs --> women always concious about going places with access to a toilet, impact on quality of life

Answer 4

--> Weakness of the pelvic floor muscles and the sphincter muscles ( the contents of the pelvis are held by a sling of muscles) --> allows urine to leak at times of increased bladder pressure --> such as laughing, coughing or when suprised

Answer 5

--> occurs when there is chronic urinary retention due to obstruction to the outflow of urine --> leads to overflow of urine without the urge to pass urine

Answer 6

anticholinergic medication --> fibroids --> pelvic tumours --> neurological conditions (MS, DN, spinal cord injuries) --> more common in males

Answer 7

--> Increased age --> Postmenopausal status --> Increase BMI --> Previous pregnancies and -----> vaginal deliveries --> Pelvic organ prolapse --> Pelvic floor surgery --> Neurological conditions, such as multiple sclerosis --> Cognitive impairment and dementia

Answer 8

--> Caffeine consumption --> Alcohol consumption --> medications --> BMI

Answer 9

Frequency of urination Frequency of incontinence Nightime urination Use of pads and change of clothing

Answer 10

--> assess pelvic tone --> examine for pelvic organ prolapse --> atrophic vagintiis --> urethral diverticulum --> pelvic mass --> strength of pelvic muscle contractions - bimanual examination - squeeze against fingers - modified oxford grading system --> ask patient to cough and watch for leackage

Answer 11

--> bladder diary should be completed, tracking fluid intake and episodes of urination and incontinence over at least three days. There should be a mix of work and leisure days. --> Urine dipstick testing should be performed to assess for infection, microscopic haematuria and other pathology. --> Post-void residual bladder volume should be measured using a bladder scan to assess for incomplete emptying. --> Urodynamic testing can be used to investigate patients with urge incontinence not responding to first-line medical treatments, difficulties urinating, urinary retention, previous surgery or an unclear diagnosis. It is not always required where the diagnosis is possible based on the history and examination.

Answer 12

--> need to stop taking anticholinergic medication and bladder medication around five days before --> thin catheter placed in the bladder and other in the rectum --> measures the pressures and compares --> cystometry - measures the detrusor muscle contraction and pressure --> uroflowmetry - measures the flow rate --> post-void residual volume

Answer 13

--> Avoiding caffeine, diuretics and overfilling of the bladder --> Avoid excessive or restricted fluid intake --> Weight loss (if appropriate) --> Supervised pelvic floor exercises for at least three months before considering surgery --> Surgery (Tension free vaginal tape and autologus sling procedures, last line - artifical urinary sphincter - pump in labia that inflates cuff around urethra --> Duloxetine is an SNRI antidepressant used second line where surgery is less preferred

Answer 14

--> Bladder retraining (gradually increasing the time between voiding) for at least six weeks is first-line --> Anticholinergic medication, for example, oxybutynin, tolterodine and solifenacin ( have anticholinergic effects which include dry mouth, dry eyes, urinary retention, constipation and worsening of dementia) --> Mirabegron is an alternative to anticholinergic medications - contraindicated in uncontrolled hypertension Invasive procedures where medical treatment fails --> Botulinum toxin type A injection into the bladder wall --> Percutaneous sacral nerve stimulation involves implanting a device in the back that stimulates the sacral nerves --> Augmentation cystoplasty involves using bowel tissue to enlarge the bladder --> Urinary diversion involves redirecting urinary flow to a urostomy on the abdomen

Answer 15

paramesonephric ducts (Mullerian ducts)

Answer 16

produce anti-mullerian hormone

Answer 17

Congenital malformation of the uterus where there is two horns in the uterus giving the uterus a heart shape Can be picked up on pelvic ultrasound scan

Answer 18

--> miscarriage --> premature birth --> malpresentation

Answer 19

--> congenital abnormality where the hymen at the entrance of the vagina is fully formed without an opening

Answer 20

--> MAy be discovered when girls start to menstruate --> menses is sealed in the vagina --> cyclical pelvic pain and cramping --> without vaginal bleeding

Answer 21

Surgical excision to create an opening

Answer 22

--> retrograde menstruation (mesntrual blood backflowing into the fallopian tubes and the ovaries --> endometriosis

Answer 23

--> error in development where a septum (wall) forms transversely across the vagina --> can either be perforate or imperforate

Answer 24

--> when perforate, girls can still menstruate, but can have difficult intercourse or tampon use --> When imperforate presents as cyclical pelvic pain and cramps without menstruation

Answer 25

--> infertility --> pregnancy-related complications

Answer 26

--> diagnosis by examination, ultrasound or MRI --> Surgical correction - complications - vaginal stenosis or recurrence

Answer 27

Abnormally small vagina

Answer 28

--> absent vagina --> these occur due to failure of the mullerian ducts to develop properly and may be associated with an absent uterus and cervix

Answer 29

--> using a vaginal dilator over a prolonged period to create an adequate vaginal size, alternativley vaginal surgery

Answer 30

Cells are unable to respond to androgen hormones, due to a lack of androgen receptors X-linked recessive condition - caused by a mutation in the androgen receptor gene on the X chromosome

Answer 31

Lack of androgen receptors through mutations in the androgen receptor gene on the X chromosome Leads to extra androgens converted into oestrogen, resulting in female secondary sexual characterisitics - previously known as testicular feminisation syndrome

Answer 32

--> Patients are genetically male, with XY sex chromosomes --> absent response to testosterone and the conversion of extra testosterone leads to the conversion of extra into oestrogen --> results in femle phenotype externally --> male sexual characteristics do not develop and patients have normal female external genitalia and breast tissue --> tests in the abdomen or inguinal canal --> absence of female reproductive system as the testes prodcue anti-mullerian hormone - only lower vagina --> insensitivity to androgens leads to lack of pubic hari and, facial hari and male muscle development , slightly taller than average female and infertile with an increased risk of testicular cancer due to testes in abdo

Answer 33

--> micropenis --> clitomegaly --> bifid scrotum --> hypospadius --> diminished male characterisitics

Answer 34

--> often presents in infanct with inguinal hernias containing testes --> can present in puberty with primary amenorrhoea --> Hormone tests - Raised LH/ normal or raised FSH/ normal or raised testosterone levels (for a male)/ raised oestrogen levels (for a male)

Answer 35

--> MDT approach - paediatrics/ gynae/ urology/ endocrinolgist/ clinical psychologist --> bilateral orchidectomy- to avoid testicular tumours --> oestrogen therapy --> vaginal dilators or vaginal surgery to create an adequate vaginal length

Answer 36

GnRH, LH, FSH, oestrogen and progesterone

Answer 37

they increase leading to female secondary sexual characteristics, the onset of the menstrual cycle and the ability to conceive children

Answer 38

-->8-14 in girls --> 9-15 in boys --> takes around 4 years from start to finish --> girls have pubertal growth spurt earlier in puberty than boys

Answer 39

Aromatase is an enzyme found in adipose tissue, important in the creation of oestrogen

Answer 40

--> low birth weight --> chronic disease --> eating disorders --> athletes

Answer 41

--> development of breast buds --> followed by pubic hair --> onset of menstrual periods --> first episode of menstruation is called menarche --> menstrual cycles begin around two years from the start of puberty

Answer 42

**Tanner staging** Age, pubic hair and breast development

Answer 43

--> GH increases initially - causes a growth spurt during the initial phases of puberty --> hypothalamus starts to secrete GnRH, first during sleep and then throughout the day in later stages --> GnRH causes the releases of FSH and LH from the pituitary gland --> FSH and LH cause the ovaries to make oestrogen and progesterone. --> FSH levels plateau about a year before menarche --> LH levels continue to rise and spike just before they induce menarche

Answer 44

--> Retrospective diagnosis, made after a women has no periods for 12 months --> defined as a permanent end to to mesntruation

Answer 45

51 years- can vary significantly

Answer 46

Describes the period of 12 months after the final menstrual period onwards

Answer 47

refers to the time around menopause when the women is experiencing **vasomotor symptoms and irregular periods**. --> includes the time leading up to the last menstrual period, and the 12 months afterwards, typically in women older than 45

Answer 48

Menopause before the age of 40 years - Result of premature ovarian insufficiency

Answer 49

Lack of ovarian follicular function = Changes in the sex hormones associated with the menstrual cycle

Answer 50

Low = Oestrogen and Progesterone High = LH and FSH in response to an absence of negative feedback from the oestrogen

Answer 51

Usually: --> In ovaries, primordial follicles mature into primary and secondary follicles --> At the start of the menstrual cycle FSH stimulates the further development of the secondary follicles --> As the follicles grow the granulosa cells that surround them secrete increasing amounts of oestrogen In menopause: --> menopause begins when there is a decline in the development of the ovarian follicles --> without the growth of the follicles there is reduced production of oestrogen --> As the levels of oestrogen fall in the perimenopausal period there is an absence of negative feedback on the pituitary gland and increasing levels of LH and FSH --> failing follicular development means that ovulation dosent occur, leading to irregular periods --> without oestrogen the endometrium dosent develop and this leads to amenorrhoea and low levels of oestrogen cause the perimenopausal symptoms

Answer 52

- Hot flushes - Emotional lability or low mood - Premenstrual syndrome - Irregular periods - Joint pains - Heavier or lighter periods - Vaginal dryness and atrophy - Reduced libido

Answer 53

- Cardiovascular disease and stroke - Osteoporosis - Pelvic organ prolapse - Urinary incontinence

Answer 54

Women over 45 (Typically around 51 for menopause) **Done clinically w/ 12+ months amenorrhea** **Can use FSH if....** - Women under 40 years with suspected premature menopause - Women aged 40 – 45 years with menopausal symptoms or a change in the menstrual cycle

Answer 55

increased risks and complications

Answer 56

Under 50? 2 years Over 50? 1 Year

Answer 57

- Barrier methods - Mirena or copper coil - Progesterone-only pill - Progesterone implant - Progesterone depot injection (under 45 years) - Sterilisation

Answer 58

Aged over 40 and up to 50 years --> as the benefits usually outweigh the risks --> Consider combined oral contraceptive pill in women over 40 years containing norethisterone or levonorgestrel in women over 40 due to low risk of venous thromboembolism

Answer 59

Weight gain Osteoporosis - Reduced bone mineral density means it is unsuitable for women over 45

Answer 60

Vasomotor symptoms = Self Limiting <5 years HRT - Tibolone - a synthetic steroid hormone that acts as continuous combined HRT - Clonidine - agonist of alpha-adrenergic and imidazoline receptors CBT/ SSRI (fluoxetine or citalopram) Testosterone (decreased libido) Vaginal oestrogen/Moisturisers (vaginal dryness and atrophy)

Answer 61

Endometrial tissue inside the myometrium (muscle layer of the uterus) --> condition is hormone dependent and usually gets better after menopause, similar to endometriosis and fibroids

Answer 62

Multiple Pregnancies Unopposed Oestrogen

Answer 63

- Dysmenorrhoea - Menorrhagia - Dyspaerunia - Infertility/ pregnancy-related complications - Maybe Asymptomatic Examination = Enlarged and tender uterus, feels more soft than an uterus with fibroids (Boggy)

Answer 64

1) TV USS 2) MRI and transabdominal ultrasound Gold) perform a histological examination of the uterus after a hysterectomy

Answer 65

**No Contraception?** Tranexamic acid (Menorrhagia) Mefenamic acid (Dysmenorrhea) NSAID - reduced bleeding and pain **Contraception?** 1) Mirena coil / COCP/ COP - Progesterone only meds such as the pill or depot may be useful **Others** GnRH analogues to induce a menopause-like state Endometrial ablation Uterine artery embolisation Myomectomy/ Hysterctomy

Answer 66

Infertility Miscarriage Preterm birth Small for gestational age Preterm premature rupture of membranes Malpresentation Need for caesarean section Postpartum haemorrhage

Answer 67

Adhesions form within the uterus following uterus damage

Answer 68

- After a pregnancy - Dilatation and curettage procedure ( scraping retained products of conception - Uterine surgery (myomectomy) or - Several pelvic infections/ PID

Answer 69

1) Damaged endometrial base layer 2) Abnormal healing w/ scar tissue adhesions 3) Scar tissue may produces unwanted connections/ blockades (does not respond to oestrogen) **Result** Physical obstructions and distort the pelvic organs, resulting in menstruation abnormalities, infertility and recurrent miscarriages

Answer 70

- Secondary amenorrhoea (absent periods) - Significantly lighter periods - Dysmenorrhoea - painful periods - Infertility

Answer 71

**Gold = Hysteroscopy** Other - **Hysterosalpingography**, where contrast is injected into the uterus and imaged with xrays - **Sonohysterography**, where the uterus is filled with fluid and a pelvic ultrasound is performed - **MRI scan**

Answer 72

Dissecting adhesions during the hysteroscopy - Reoccurence of the adhesions after treatment is common

Answer 73

Chronic inflammatory skin condition that presents with **patches of white shiny porcelain-white skin** - Affects the labia, perineum, and perianal skin in the skin - Autoimmune condition associated with type 1 diabetes, alopecia, hypothyroid and vitiligo

Answer 74

Clinical diagnosis Can confirm w/ Vulval Biopsy

Answer 75

Flat eruption that spreads

Answer 76

Chronic inflammation and irritation caused by **repeated scratching and rubbing of an area of skin** - Presents with excoriations, plaques, scaling and thickened skin

Answer 77

Autoimmune condition that causes localised chronic inflammation with **shiny, purplish, flat-topped raised areas with white lines across the surface** called Wickham’s striae.

Answer 78

- **Vulval Itching and Skin changes** - Soreness and pain possibly worse at night - Skin tightness - Superficial dyspareunia - Erosions and Fissures - Koebner Phenomenon **Koebner Phenomenon** Worse by friction to the skin. This occurs with lichen sclerosus. It can be made worse by **tight underwear that rubs the skin, urinary incontinence and scratching**.

Answer 79

Labia/ Perianal/Perineal Changes - Fissures/ Cracks/ Erosions “Porcelain-white” in colour Shiny Thin Tight Skin Slightly Raised - Papules or plaques

Answer 80

1st) Clobetasol propionate **0.05% (dermovate)** - control symptoms and reduce risk of malignancy 2) Regular emollient use

Answer 81

**5% Risk of Vulval Small Cell Carcinoma** Other complications include: - Pain and discomfort - Sexual dysfunction - Bleeding - Narrowing of the vaginal or urethral openings

Answer 82

Low Oestrogen = Vaginal Mucosa Dryness and Thinning Px = Genitourinary symptom of menopause

Answer 83

--> Epithelial lining of the vagina and urinary tracct responds to oestrogen by becoming thicker, more elastic and producing more secretions --> menopause, oestrogen levels fall and mucosa becomes thinner, less elastic and more dry, tissues prone to inflammation --> changes the vaginal pH and microbial flora that can contribute to localised infections --> oestrogen helps maitain healthy connective tissue around the pelvic organs and a lack of oestrogen can contribute to POP and stress incontinence

Answer 84

--> presents in postmenopausal women with symptoms of --> itching --> dryness --> dyspareunia - painful sex --> bleeding due to localised inflammation --> recurrent urinary tract infections, stress incontinece or POP

Answer 85

Pale mucosa Thin skin Reduced skin folds Erythema and inflammation Dryness Sparse pubic hair

Answer 86

--> 90% squamous cell carcinomas --> less commonly they can be malignant melanomas

Answer 87

--> advanced age --> immunosuppression --> HPV - humanpapilloma virus infection --> lichen sclerosus - 5% of women with lichen sclerosus get vulval cancer

Answer 88

--> Premalignant condition affecting the squamous epithelium of the skin that can precede vulval cancer

Answer 89

--> Type of vulval intraepithelial neoplasia --> associated with HPV infections that typically occur in younger women aged 35-50 years

Answer 90

--> alternate type of VIN and associated with lichen sclerosis and typically occurs in older women 50-60

Answer 91

--> Watch and wait with close followup --> Wide local excision (surgery) to remove the lesion --> Imiquimod cream --> Laser ablation

Answer 92

--> may be an incidental finding in older women, for example, during catheterisation in a patient with dementia. --> Vulval lump --> Ulceration --> Bleeding --> Pain --> Itching --> Lymphadenopathy in the groin Vulval cancer most frequently affects the labia majora, giving an appearance of: --> Irregular mass --> Fungating lesion --> Ulceration --> Bleeding

Answer 93

--> 2ww referral --> Biopsy of the lesion and sentinel node biopsy - lymph node spread --> Further staging imaging such as CT of the abdomen and pelvis

Answer 94

International Federation of Gynecology and Obstetrics - FIGO system

Answer 95

--> wide local excision to remove the cancer --> groin lymph node dissection --> chemotherapy --> radiotherapy

Answer 96

--> younger women --> peaking in reproductive years

Answer 97

--> 80% are squamous cell carcinoma --> Adenocarcinoma next most common --> Small cell cancer rare

Answer 98

HPV - human papillomavirus

Answer 99

anal, vulval, vaginal, penis, mouth and throat cancers --> sexually transmitted infection

Answer 100

HPV inhibits the tumour suppressor genes

Answer 101

Increased risk of catching HPV --> early sexual activity --> Increased number of sexual partners --> Sexual partners who have had more partners --> Not using condoms Non-engagement with cervical screening --> Most cases are preventable with early detection and treatment Other risk factors --> smoking --> HIV --> combined oral contraceptive --> Increased number of full-term pregnancies --> family history --> Exposure to diethylstilbesterol during fetal development

Answer 102

--> may be detected during cervical smears in asymptomatic women --> abnormal vaginal bleeding - intermenstrual/postcoital/post-menopausal bleeding --> vaginal discharge --> pelvic pain --> dyspareunia - pain or discomfort with sex --> ulceration/inflammation.bleeding or visible tumour in the cervix

Answer 103

grading system for the level if dysplasia (premalignant change) in the cells of the cervix

Answer 104

through colposcopy

Answer 105

--> CIN I: mild dysplasia, affecting 1/3 the thickness of the epithelial layer, likely to return to normal without treatment --> CIN II: moderate dysplasia, affecting 2/3 the thickness of the epithelial layer, likely to progress to cancer if untreated --> CIN III: severe dysplasia, very likely to progress to cancer if untreated CIN III is sometimes called cervical carcinoma in situ.

Answer 106

--> smear test --> aims to pick up precancerous changes (dyskaryosis) --> liquid-based cytology- brush into a preservation fluid --> initially tested for high-risk HPV before the cells are examined, if the sameple is negative the cells arn't examined and the women returned to the routine screening programme

Answer 107

Every three years aged 25 – 49 Every five years aged 50 – 64

Answer 108

Women with HIV are screened annually Women over 65 may request a smear if they have not had one since aged 50 Women with previous CIN may require additional tests (e.g. test of cure after treatment) Certain groups of immunocompromised women may have additional screening (e.g. women on dialysis, cytotoxic drugs or undergoing an organ transplant) Pregnant women due a routine smear should wait until 12 weeks post-partum

Answer 109

Inadequate Normal Borderline changes Low-grade dyskaryosis High-grade dyskaryosis (moderate) High-grade dyskaryosis (severe) Possible invasive squamous cell carcinoma Possible glandular neoplasia

Answer 110

--> Inadequate sample – repeat the smear after at least three months --> HPV negative – continue routine screening --> HPV positive with normal cytology – repeat the HPV test after 12 months --> HPV positive with abnormal cytology – refer for colposcopy

Answer 111

Involves inserting a speculum and a colposcope to magnify the cervix. This allows the epithelial lining of the cervix to be examined in detail. During colposcopy, stains such as acetic acid and iodine solution can be used to differentiate abnormal areas. A punch biopsy or large loop excision of the transformational zone can be performed during the colposcopy procedure to get a tissue sample.

Answer 112

also known as loop biopsy --> loop of wire with diathermy to removal abnormal tissue of the cervix --> may result in pre-term labour

Answer 113

--> Treatment for cervical intraepithelial neoplasia and very early-stage cervical cancer --> General anesthetic - surgeon removes a cone-shaped piece of the uterus - sent to histology --> increased risk of misscarriage, premature labour, pain, bleeding, infection, and scar formation with stenosis of the cervix

Answer 114

The International Federation of Gynaecology and Obstetrics (FIGO) staging system is used to stage cervical cancer: Stage 1: Confined to the cervix Stage 2: Invades the uterus or upper 2/3 of the vagina Stage 3: Invades the pelvic wall or lower 1/3 of the vagina Stage 4: Invades the bladder, rectum or beyond the pelvis

Answer 115

--> Cervical intraepithelial neoplasia and early-stage 1A: LLETZ or cone biopsy --> Stage 1B – 2A: Radical hysterectomy and removal of local lymph nodes with chemotherapy and radiotherapy --> Stage 2B – 4A: Chemotherapy and radiotherapy --> Stage 4B: Management may involve a combination of surgery, radiotherapy, chemotherapy, and palliative care --> Pelvic exenteration - may be used in advanced cervical cancer - removal of most or all of the pelvic organs including the vagina, cervix, uterus, fallopian tubes, ovaries, bladder, and rectum Bevacizumab - is a monoclonal antibody that may be used in combination with other chemotherapies in the treatment of metastatic or recurrent cervical cancer targets vascular endothelial growth factor a

Answer 116

--> before they become sexually active

Answer 117

Strains 6 and 11 cause genital warts Strains 16 and 18 cause cervical cancer

Answer 118

--> endometerial cancer

Answer 119

Endometrial cancer is cancer of the endometrium, the lining of the uterus. Around 80% of cases are adenocarcinoma. It is an oestrogen-dependent cancer, meaning that oestrogen stimulates the growth of endometrial cancer cells.

Answer 120

--> precancerous condition involving the thickening of the endometrium --> most cases of endometrial hyperplasia will return to normal overtime

Answer 121

--> hyperplasia without atypia --> atypical hyperplasia

Answer 122

progestogens --> intrauterine system - mirena coil --> continued oral progestogens - levonorgestrel

Answer 123

--> Patient's exposure to unopposed oestrogen, refers to oestrogen without progesterone Situations where there is an increased unopposed oestrogen --> increased age --> earlier onset of menstruation --> late menopause --> oestrogen-only HRT --> no or fewer pregnancies --> obesity --> polycystic ovarian syndrome --> tamoxifen --> diabetes

Answer 124

--> After ovulation, corpus luteum forms in the ovaries from the ruptured follicle that released the egg --> Corpus luteum produced progesterone, providing endometrial protection during the luteal phase of the menstrual cycle (second half) --> PCOS - less likely to ovulate and form a corpus luteum, progesterone not produced --> endometrial lining has more exsposure to unopposed oestrogen

Answer 125

--> combined oral contraceptive pill --> an intrauterine system (mirena coil) --> cyclical progestogens

Answer 126

--> adipose tissue (fat) is a source of oestrogen. --> Adipose tissue is the primary source of oestrogen in postmenopausal women. --> Adipose tissue contains aromatase, which is an enzyme that converts androgens such as testosterone into oestrogen. --> Androgens are produced mainly by the adrenal glands. In women with more adipose tissue, and therefore more aromatase enzyme, more of these androgens are converted to oestrogen. --> This extra oestrogen is unopposed in women that are not ovulating (e.g. PCOS or postmenopause), because there is no corpus luteum to produce progesterone.

Answer 127

--> Combined contraceptive pill --> Mirena coil --> Increased pregnancies --> Cigarette smoking Smoking appears to be protective against endometrial cancer in postmenopausal women by being anti-oestrogenic. Interestingly, it is not protective against other oestrogen dependent cancers, such as breast cancer (where it increases the risk).

Answer 128

The number one presenting symptom of endometrial cancer to remember for your exams is postmenopausal bleeding. Endometrial cancer may also present with: Postcoital bleeding Intermenstrual bleeding Unusually heavy menstrual bleeding Abnormal vaginal discharge Haematuria Anaemia Raised platelet count

Answer 129

The referral criteria for a 2-week-wait urgent cancer referral for endometrial cancer is: Postmenopausal bleeding (more than 12 months after the last menstrual period) NICE also recommends referral for a transvaginal ultrasound in women over 55 years with: Unexplained vaginal discharge Visible haematuria plus raised platelets, anaemia or elevated glucose levels

Answer 130

Transvaginal ultrasound for endometrial thickness (normal is less than 4mm post-menopause) Pipelle biopsy, which is highly sensitive for endometrial cancer making it useful for excluding cancer Hysteroscopy with endometrial biopsy

Answer 131

The International Federation of Gynaecology and Obstetrics (FIGO) staging system is used to stage endometrial cancer: Stage 1: Confined to the uterus Stage 2: Invades the cervix Stage 3: Invades the ovaries, fallopian tubes, vagina or lymph nodes Stage 4: Invades bladder, rectum or beyond the pelvis

Answer 132

The usual treatment for stage 1 and 2 endometrial cancer is a total abdominal hysterectomy with bilateral salpingo-oophorectomy, also known as a TAH and BSO (removal of uterus, cervix and adnexa). Other treatment options depending on the individual presentation include: A radical hysterectomy involves also removing the pelvic lymph nodes, surrounding tissues and top of the vagina Radiotherapy Chemotherapy Progesterone may be used as a hormonal treatment to slow the progression of the cancer

Answer 133

--> non- specific symptoms resulting in a worse prognosis --> more than 70% of women present with ovarian cancer once it has spread beyond the pelvis

Answer 134

Epithelial cell tumours Dermoid cysts/ germ cell tumours Sex cord-stromal tumours metastasis

Answer 135

--> tumours arising from the epithelial cells of the ovary --> most common type --> subtypes include - serous tumours (most common)/ endometrioid carcinomas/ clear cell tumours/ mucinous tumours/ undifferentiated tumours

Answer 136

--> benign ovarian tumours - teratomas, they come from germ cells --> may contain various tissue types such as skin, hair, teetch, bone --> associated with ovarian torsion. --> germ cell tumours may cause a raised alpha-fetoprotein and hCG

Answer 137

--> rare tumours that can be benign or malignant - arise from stroma (connective tissue) or sex cords (emryonic structure assocaited with follicles) --> several types such as sertoli-leydig tumours and granulosa cell tumours

Answer 138

--> metastasis in the ovary usually from gastrointestinal tract cancer paritcularly the stomach

Answer 139

--> Age (peaks age 60) --> BRCA1 and BRCA2 genes (consider the family history) --> Increased number of ovulations --> Obesity --> Smoking --> Recurrent use of clomifene (inferitlity treatment which causes ovulation) Factors that increase the number of ovulations, increase the risk of ovarian cancer. These include: -->Early-onset of periods --> Late menopause --> No pregnancies

Answer 140

Having a higher number of lifetime ovulations increases the risk of ovarian cancer. Factors that stop ovulation or reduce the number of lifetime ovulations, reduce the risk: Combined contraceptive pill Breastfeeding Pregnancy

Answer 141

Ovarian cancer can present with non-specific symptoms. In older women, keep the possibility of ovarian cancer in mind and have a low threshold for considering further investigations. Symptoms that may indicate ovarian cancer include: --> Abdominal bloating --> Early satiety (feeling full after eating) --> Loss of appetite --> Pelvic pain --> Urinary symptoms (frequency / urgency) --> Weight loss --> Abdominal or pelvic mass --> Ascites An ovarian mass may press on the obturator nerve and cause referred hip or groin pain. The obturator nerve passes along the inside of the pelvic, lateral to the ovaries, where an ovarian mass can compress it.

Answer 142

Ascites Pelvic mass (unless clearly due to fibroids) Abdominal mass

Answer 143

CA-125 - cancer antigen 125

Answer 144

initial investigations in primary or secondary care are: --> CA125 blood test (>35 IU/mL is significant) --> Pelvic ultrasound The risk of malignancy index (RMI) estimates the risk of an ovarian mass being malignant, taking account of three things: --> Menopausal status --> Ultrasound findings --> CA125 level Further investigations in secondary care include: --> CT scan to establish the diagnosis and stage the cancer --> Histology (tissue sample) using a CT guided biopsy, laparoscopy or laparotomy --> Paracentesis (ascitic tap) can be used to test the ascitic fluid for cancer cells Women under 40 years with a complex ovarian mass require tumour markers for a possible germ cell tumour: --> Alpha-fetoprotein (α-FP) --> Human chorionic gonadotropin (HCG)

Answer 145

--> Endometriosis --> Fibroids --> Adenomyosis --> Pelvic infection --> Liver disease --> Pregnancy

Answer 146

The International Federation of Gynaecology and Obstetrics (FIGO) staging system is used to stage ovarian cancer. A very simplified version of this staging system is: Stage 1: Confined to the ovary Stage 2: Spread past the ovary but inside the pelvis Stage 3: Spread past the pelvis but inside the abdomen Stage 4: Spread outside the abdomen (distant metastasis)

Answer 147

Ovarian cancer will be managed by a specialist gynaecology oncology MDT. It usually involves a combination of surgery and chemotherapy.

Answer 148

--> where there is ectopic endometrial tissue outside the uterus

Answer 149

endometrioma

Answer 150

Chocolate cysts

Answer 151

--> genetic component --> retrograde menstruation - where ther endometrial lining flows back out into the pelvis and peritoneum --> embryonic cells destined to become endometrial tissue may remian outside the uterus --> may be spread of endometrial cells through the lympahtic system similar to cancer --> Cells outside the uterus someohow change - metaplasia

Answer 152

--> endometrial tissue respond to hormones same as in uterus --> during menstruation the endometrial tissue sheds and bleeds --> with endometriosis this bleeding causes irritation and inflammation of the tissues around the site of endometriosis --> results in cyclical, dull, heavy or burning pain during menstruation --> deposits of endometriosis in the bladder or the bowel can lead to blood in the urine or stool --> localised inflammation and bleeding can lead to adhesions, causes scar tissue - adhesions and binds the organs together --> adhesions lead to chronic - non-cyclical pain that can be sharp, stabbing or pulling and associted with nausea --> inferitlity due to adhesions blocking egg release and chcoloate cysts damaging eggs

Answer 153

--> Cyclical abdominal or pelvic pain --> Deep dyspareunia (pain on deep sexual intercourse) --> Dysmenorrhoea (painful periods) --> Infertility --> Cyclical bleeding from other sites, such as haematuria --> There can also be cyclical symptoms relating to other areas affected by the endometriosis: --> Urinary symptoms --> Bowel symptoms Examination may reveal: --> Endometrial tissue visible in the vagina on speculum examination, --> particularly in the posterior fornix --> A fixed cervix on bimanual examination --> Tenderness in the vagina, cervix and adnexa

Answer 154

Pelvic ultrasound may reveal large endometriomas and chocolate cysts. Ultrasound scans are often unremarkable in patients with endometriosis. Patients with suspected endometriosis need referral to a gynaecologist for laparoscopy. Laparoscopic surgery is the gold standard way to diagnose abdominal and pelvic endometriosis. A definitive diagnosis can be established with a biopsy of the lesions during laparoscopy. Laparoscopy has the added benefit of allowing the surgeon to remove deposits of endometriosis and potentially improve symptoms.

Answer 155

Initial management involves: -->Establishing a diagnosis --> Providing a clear explanation --> Listening to the patient, establishing their ideas, concerns and expectations and building a partnership --> Analgesia as required for pain (NSAIDs and paracetamol first line) Hormonal management options can be tried before establishing a definitive diagnosis with laparoscopy - Cyclical pain can be treated with hormonal medications that stop ovulation and reduce endometrial thickening. This can be achieved using the combined oral contraceptive pill, oral progesterone-only pill, the progestin depot injection, the progestin implant (Nexplanon) and the Mirena coil. The cyclical pain tends to improve after the menopause when the female sex hormones are reduced. Therefore, another treatment option for endometriosis is to induce a menopause-like state using GnRH agonists. Examples of GnRH agonists are goserelin (Zoladex) or leuprorelin (Prostap). They shut down the ovaries temporarily and can be useful in treating pain in many women. However, inducing the menopause has several side effects, such as hot flushes, night sweats and a risk of osteoporosis. Combined oral contractive pill, which can be used back to back without a pill-free period if helpful Progesterone only pill Medroxyprogesterone acetate injection (e.g. Depo-Provera) Nexplanon implant Mirena coil GnRH agonists Surgical management options: Laparoscopic surgery to excise or ablate the endometrial tissue and remove adhesions (adhesiolysis) Hysterectomy Laparoscopic treatment may improve fertility. Hormonal therapies may improve symptoms but not fertility.

Answer 156

type of pituitary adenoma, a benign tumor of the pituitary gland

Answer 157

--> Size - microadenoma < 1cm and macroadenoma is > 1cm --> Hormonal status - secretory/ functioning adenoma produces an excess of a particular hormone and non-secretory adenoma does not produce a hormone to excess

Answer 158

--> prolactinomas are the most common --> produce prolactin

Answer 159

excess prolactin in women --> amenorrhoea --> infertility --> galactorrhoea --> osteoporosis excess prolactin in men --> impotence --> loss of libido --> galactorrhoea other symptoms may be seen with macroadenomas --> headache. --> visual disturbances (classically, a bitemporal hemianopia (lateral visual fields) or upper temporal quadrantanopia) symptoms and signs of hypopituitarism

Answer 160

--> symptomatic - dopamine agonists e.g cabergoline or bromocriptine which inhibits the release of prolactin from the pituitary gland --> surgery is performed for patients who cant tolerate or fail to respond to the medical therapy - trans-sphenoidal approach

Answer 161

benign tumors of the smooth muscle of the uterus - also called uterine leiomyomas --> very common --> more common in black women --> oestrogen sensitive

Answer 162

--> Intramural means within the myometrium (the muscle of the uterus). As they grow, they change the shape and distort the uterus. --> Subserosal means just below the outer layer of the uterus. These fibroids grow outwards and can become very large, filling the abdominal cavity. --> Submucosal means just below the lining of the uterus (the endometrium). --> Pedunculated means on a stalk.

Answer 163

Fibroids are often asymptomatic. They can present in several ways: --> Heavy menstrual bleeding (menorrhagia) is the most frequent presenting symptom --> Prolonged menstruation, lasting more than 7 days --> Abdominal pain, worse during menstruation --> Bloating or feeling full in the abdomen --> Urinary or bowel symptoms due to pelvic pressure or fullness --> Deep dyspareunia (pain during intercourse) --> Reduced fertility --> Abdominal and bimanual examination may reveal a palpable pelvic mass or an enlarged firm non-tender uterus.

Answer 164

Hysteroscopy is the initial investigation for submucosal fibroids presenting with heavy menstrual bleeding. Pelvic ultrasound is the investigation of choice for larger fibroids. MRI scanning may be considered before surgical options, where more information is needed about the size, shape and blood supply of the fibroids.

Answer 165

For fibroids less than 3 cm, the medical management is the same as with heavy menstrual bleeding: --> Mirena coil (1st line) – fibroids must be less than 3cm with no distortion of the uterus --> Symptomatic management with NSAIDs and tranexamic acid --> Combined oral contraceptive --> Cyclical oral progestogens Surgical options for managing smaller fibroids with heavy menstrual bleeding are: --> Endometrial ablation --> Resection of submucosal fibroids during hysteroscopy --> Hysterectomy For fibroids more than 3 cm, women need referral to gynaecology for investigation and management. Medical management options are: --> Symptomatic management with NSAIDs and tranexamic acid --> Mirena coil – depending on the size and shape of the fibroids and uterus --> Combined oral contraceptive --> Cyclical oral progestogens Surgical options for larger fibroids are: --> Uterine artery embolisation - causes fibroid shrinkage --> Myomectomy - can improve fertility --> Hysterectomy --> GnRH agonists, such as goserelin (Zoladex) or leuprorelin (Prostap), may be used to reduce the size of fibroids before surgery. They work by inducing a menopause-like state and reducing the amount of oestrogen maintaining the fibroid. Usually, GnRH agonists are only used short term, for example, to shrink a fibroid before myomectomy.

Answer 166

--> Heavy menstrual bleeding, often with iron deficiency anaemia --> Reduced fertility --> Pregnancy complications, such as miscarriages, premature labour and obstructive delivery --> Constipation --> Urinary outflow obstruction and urinary tract infections --> Red degeneration of the fibroid --> Torsion of the fibroid, usually affecting pedunculated fibroids --> Malignant change to a leiomyosarcoma is very rare (<1%)

Answer 167

--> ischemia, infarction and necrosis of the fibroid due to disrupted blood supply. --> more likely to occur in larger fibroids (above 5 cm) during the second and third trimester of pregnancy. --> Red degeneration may occur as the fibroid rapidly enlarges during pregnancy, outgrowing its blood supply and becoming ischaemic. It may also occur due to kinking in the blood vessels as the uterus changes shape and expands during pregnancy. --> Red degeneration presents with severe abdominal pain, low-grade fever, tachycardia and often vomiting. Management is supportive, with rest, fluids and analgesia

Answer 168

--> infection and inflammation of the female pelvic organs including the uterus, fallopian tubes, ovaries and the surrounding peritoneum

Answer 169

--> ascending infection from the endocervix --> chlamydia trachomatis --> Neisseria gonorrhoea --> mycoplasma genitalium

Answer 170

--> lower abdominal pain --> fever --> deep dyspareunia --> Dysuria and menstrual irregularities may occur --> vaginal or cervical discharge --> cervical excitation

Answer 171

--> a pregnancy test should be done to exclude an ectopic pregnancy --> high vaginal swab -these are often negative --> screen for Chlamydia and Gonorrhoea

Answer 172

--> Due to the difficulty in making an accurate diagnosis and the potential complications of untreated PID, consensus guidelines recommend having a low threshold for treatment --> oral ofloxacin + oral metronidazole or intramuscular ceftriaxone + oral doxycycline + oral metronidazole --> RCOG guidelines suggest that in mild cases of PID intrauterine contraceptive devices may be left in

Answer 173

--> Perihepatitis (Fitz-Hugh Curtis Syndrome) - occurs in around 10% of cases/ it is characterised by right upper quadrant pain and may be confused with cholecystitis --> Infertility - the risk may be as high as 10-20% after a single episode --> Chronic pelvic pain --> ectopic pregnancy

Answer 174

--> cysts related to fluctuating hormones of the menstrual cycle --> very common in premenopausal women (benign)

Answer 175

Malignancy

Answer 176

String of pearls

Answer 177

--> Most are asymptomatic --> vague pelvic pain --> vague bloating --> vague fullness in the abdomen --> a palpable pelvic mass (large cysts - mucinous cystadenomas)

Answer 178

--> ovarian torsion --> haemorrhage --> rupture of the cyst

Answer 179

--> follicular cysts - when the developing follicle fails to rupture and release the egg/ most common/ harmless and disappear after a few menstrual cycles/thin-walled and no internal structures. --> corpus luteum cysts - corpus luteum fails to break down and instead fills with fluid/ causes pelvic pain or delayed menstruation/ often in early pregnancy

Answer 180

--> Serous cystadenoma - benign tumour from epithelial cells --> Mucinous cystadenoma - benign tumour from epithelial - can be huge --> Endometrioma - lumps of endometrial tissue in the ovary - only in endometriosis - causes pain and disrupts ovulation --> Dermoid/germ cell tumours - benign tumours - teratomas (come from germ cells) can contain various tissues (hair, skin, teeth and bone) associated with ovarian torsion --> Sex cord-stromal tumours - rare - benign or malignant - from stroma (connective tissue) or sex cords (embryonic structures associated with follicles. - includes Sertoli-Leydig cell tumours and granulosa cell tumours

Answer 181

--> Age --> Postmenopause --> Increased number of ovulations --> Obesity --> Hormone replacement therapy --> Smoking --> Breastfeeding (protective) --> Family history and BRCA1 and BRCA2 genes

Answer 182

Later onset of periods (menarche) Early menopause Any pregnancies Use of the combined contraceptive pill

Answer 183

--> Premenopausal women with a simple ovarian cyst less than 5cm on ultrasound do not need further investigations. --> blood test - CA125 --> women under 40 with complex ovarian mass require tumour markers for possible germ cell tumour: Lactate dehydrogenase/ alpha-fetoprotein/ HCG --> Risk of malignancy index: menopausal status/ USS findings/ CA125 level

Answer 184

Endometriosis Fibroids Adenomyosis Pelvic infection Liver disease Pregnancy

Answer 185

--> Possible ovarian cancer (complex cysts or raised CA125) requires a two-week wait referral to a gynaecological oncology specialist. --> Possible dermoid cysts require referral to a gynaecologist for further investigation and consideration of surgery. --> Simple ovarian cysts in premenopausal women can be managed based on their size: < 5cm cysts will almost always resolve within three cycles. They do not require a follow-up scan. / 5cm to 7cm: Require routine referral to gynaecology and yearly ultrasound monitoring/ More than 7cm: Consider an MRI scan or surgical evaluation as they can be difficult to characterise with ultrasound. Cysts in postmenopausal women generally require correlation with the CA125 result and referral to a gynaecologist. When there is a raised CA125, this should be a two-week wait suspected cancer referral. Simple cysts under 5cm with a normal CA125 may be monitored with an ultrasound every 4 – 6 months. Persistent or enlarging cysts may require surgical intervention (usually with laparoscopy). Surgery may involve removing the cyst (ovarian cystectomy), possibly along with the affected ovary (oophorectomy).

Answer 186

Torsion Hemorrhage into the cyst Rupture, with bleeding into the peritoneum

Answer 187

Meig’s syndrome involves a triad of: --> Ovarian fibroma (a type of benign ovarian tumor) --> Pleural effusion --> Ascites Meig’s syndrome typically occurs in older women. Removal of the tumour results in complete resolution of the effusion and ascites.

Answer 188

Ovarian torsion is a condition where the ovary twists in relation to the surrounding connective tissue, fallopian tube and blood supply (the adnexa).

Answer 189

--> Usually due to an ovarian mass larger than 5cm such as cyst or tumour ---> more likely with benign tumours and more likely to occur during pregnancy

Answer 190

Twisting of the adnexa and blood supply to the ovary leads to ischemia. If the torsion persists, necrosis will occur, and the function of that ovary will be lost. Therefore, ovarian torsion is an emergency, where a delay in treatment can have significant consequences. Prompt diagnosis and management is essential.

Answer 191

--> Sudden onset severe unilateral pelvic pain --> Nausea and vomiting --> localised tenderness --> palpable mass in the pelvis --> can be intermittent pain if the ovary and untwist spontaneously

Answer 192

Pelvic ultrasound is the initial investigation of choice. Transvaginal is ideal, but transabdominal can be used where transvaginal is not possible. It may show a “whirlpool sign”, free fluid in pelvis and oedema of the ovary. Doppler studies may show a lack of blood flow. The definitive diagnosis is made with laparoscopic surgery

Answer 193

--> may require laparoscopic surgery --> Untwist the ovary and fix in it place (detorsion) --> Remove the affected ovary (oophorectomy)

Answer 194

--> A delay in treating ovarian torsion can lead to loss of function. Other ovaries can compensate so fertility is not affected --> When necrotic ovary is removed it can become affected developing an abscess and this can lead to sepsis, it can also rupture resulting in peritonitis and adhesions

Answer 195

--> Common condition causing metabolic and reproductive problems in women --> Characteristic features of multiple ovarian cysts/ oligomenorrhoea/ hyperandrogenism and insulin resistance

Answer 196

Rotterdam criteria --> at least 2 out of 3 features --> Oligoovulation or anovulation - presenting with irregular or absent menstrual periods --> hyperandrogenism - hirsutisim and acne --> polycystic ovaries on ultrasound

Answer 197

--> Triad of - anovulation (oligomenorrhoea/amenorrhoea) / hyperandrogenism ( Hirsutism and acne)/ Polycystic ovaries on ultrasound --> infertility --> Hair loss in a male pattern --> insulin resistance and diabetes --> acanthosis nigricans (insulin resistance) --> endometrial hyperplasia and cancer --> cardiovascular disease --> hypercholesterolemia --> obstructive sleep apnoea --> depression and anxiety --> sexual problems

Answer 198

--> Medications, such as phenytoin, ciclosporin, corticosteroids, testosterone, and anabolic steroids --> Ovarian or adrenal tumors that secrete androgens --> Cushing’s syndrome --> Congenital adrenal hyperplasia

Answer 199

Insulin resistance is a crucial part of PCOS. When someone is resistant to insulin, their pancreas has to produce more insulin to get a response from the cells of the body. Insulin promotes the release of androgens from the ovaries and adrenal glands. Therefore, higher levels of insulin result in higher levels of androgens (such as testosterone). Insulin also suppresses sex hormone-binding globulin (SHBG) production by the liver. SHBG normally binds to androgens and suppresses their function. Reduced SHBG further promotes hyperandrogenism in women with PCOS. The high insulin levels contribute to halting the development of the follicles in the ovaries, leading to anovulation and multiple partially developed follicles (seen as polycystic ovaries on the scan). Diet, exercise and weight loss help reduce insulin resistance.

Answer 200

BLOODS --> testosterone --> Sex hormone-binding globulin --> LH --> FSH --> Prolactin - might be slightly elevated --> TSH --> Raised LH --> Raised LH: FSH ratio --> Raised testosterone --> raised insulin --> normal or raised oestrogen levels --> TVU - the follicles may be arranged around the periphery of the ovary giving a string of pearls appearance - 12 or more developing follicles in one ovary or a ovarian volume >10cm3 --> Diabetes - 2hr OGTT --> Impaired fasting glucose – fasting glucose of 6.1 – 6.9 mmol/l (before the glucose drink) --> Impaired glucose tolerance – plasma glucose at 2 hours of 7.8 – 11.1 mmol/l --> Diabetes – plasma glucose at 2 hours above 11.1 mmol/l

Answer 201

reduce the risks associated with obesity, type 2 diabetes, hypercholesterolemia, and cardiovascular disease. These risks can be reduced by: Weight loss - significant management - can improve insulin resistance, reduce the risks of associated conditions and reduce hirsutism - orlistat for bmi >30 - lipase inhibitor stops fat absorption. Low glycaemic index, calorie-controlled diet Exercise Smoking cessation Antihypertensive medications where required Statins where indicated (QRISK >10%) Patients should be assessed and managed for the associated features and complications, such as: Endometrial hyperplasia and cancer Infertility Hirsutism Acne Obstructive sleep apnoea Depression and anxiety

Answer 202

Women with polycystic ovarian syndrome have several risk factors for endometrial cancer: Obesity Diabetes Insulin resistance Amenorrhoea

Answer 203

--> Normally corpus luteum secretes progesterone --> PCOS - anovulation - less progesterone - more unopposed oestrogen --> Continuous oestrogen leads to endometrial lining proliferation without regular shedding as there's no progesterone --> similar to unopposed oestrogen in women on HRT - leads to endometrial hyperplasia

Answer 204

--> pelvic ultrasound scan if extended gaps in periods or abnormal bleeding, cyclical progestogens are given to induce period before scan - if >10mm referred for biopsy --> Mirena coil for continuous endometrial protection --> Inducing a withdrawal bleed at least every 3 – 4 months with either: Cyclical progestogens (e.g. medroxyprogesterone acetate 10mg once a day for 14 days)/ Combined oral contraceptive pill

Answer 205

--> Weight loss to help restore regular ovulation --> Clomifene --> laparoscopic ovarian drilling --> IVF --> if pregnant require OGTT at 24-28 weeks gestation

Answer 206

--> Weight loss --> Co-cyprinidiol is a COCP licensed for the treatment of hirsutism and acne - anti-androgenic effect. Increased risk of VTE so only 3 months of use allowed --> topical eflornithine --> electrolysis --> Laser hair removal --> Spironolactone (mineralocorticoid antagonist with anti-androgen effects) --> Finasteride (5α-reductase inhibitor that decreases testosterone production) --> Flutamide (non-steroidal anti-androgen) --> Cyproterone acetate (anti-androgen and progestin)

Answer 207

--> COCP first line --> Co-cyprinidiol - however increased risk for VTE despite anti-androgenic effect --> Topical adapalene (a retinoid) --> Topical antibiotics (e.g. clindamycin 1% with benzoyl peroxide 5%) --> Topical azelaic acid 20% --> Oral tetracycline antibiotics (e.g. lymecycline)

Answer 209

Complete mole Partial mole

Answer 210

**Two sperm cells fertilise an empty ovum** that contains no genetic material - These sperm then combine genetic material, and the cells start to divide and grow into a tumour called a complete mole. - No fetal material will form.

Answer 211

**Two sperm cells fertilise a normal ovum** (containing genetic material) at the same time. - The new cell now has three sets of chromosomes (it is a haploid cell). - The cell divides and multiplies into a tumour called a partial mole - Some fetal material may form

Answer 212

Periods will stop and the hormonal changes of pregnancy will occur. **Clinically** - More severe morning sickness - Vaginal bleeding - Increased enlargement of the uterus - Abnormally high hCG - Thyrotoxicosis (hCG can mimic TSH and stimulate the thyroid to produce excess T3 and T4) **Pelvis USS = Snowstorm** Can confirm w/ biopsy of resected mole

Answer 247

A gestational sac is present but contains **no embryo**

Answer 248

**Transvaginal ultrasound** - Mean gestational sac diameter - Fetal pole and crown-rump length - fetal pole expected when the mean gestational sac diameter is 25mm or more, if no fetal pole at 25mm gestational sac diameter it is repeated after a week to confirm anembryonic pregnancy - Fetal heartbeat - expected when the crown-rump length is 7mm or more. if heartbeat the pregnancy is considered to be viable / when there is a crown-rump length of 7mm or more with no heartbeat the scan is repeated in a week's time to confirm a non-viable pregnancy

Answer 249

< 6 weeks gestation - presenting with bleeding - expectant providign no pain or other complications such as previous ectopic pregnancy - awaiting miscarriage without investigations or treatment - too small to see on USS. Repeat urine pregnanacy test performed after 7-10 days, if negative a miscarriage can be confirmed. if bleeding continues then further investigations > 6 weeks Expectant management (do nothing and await a spontaneous miscarriage) Medical management (misoprostol) Surgical management

Answer 250

Spontaneous miscarriage by waiting <2 weeks -Repeat urine pregnancy test should be three weeks after bleeding and pain settle to confirm the miscarriage is complete. Persistent or worsening bleeding requires further assessment and repeat ultrasound, as this may indicate an incomplete miscarriage and require additional management.

Answer 260

**Two registered medical practitioners must sign to agree abortion is indicated** It must be carried out by a registered medical practitioner in an NHS hospital or approved premise

Answer 261

A medical abortion is most appropriate earlier in pregnancy but can be used at any gestation. It involves two treatments: Mifepristone (anti-progestogen) Misoprostol (prostaglandin analogue) 1 – 2 day later Rheusus negative women with gestational age of 10 weeks or above having a medical TOP should have anti-D prophylaxis

Answer 262

**Preparation** Medications are used for cervical priming. This involves softening and dilating the cervix with **misoprostol, mifepristone, or osmotic dilators. Osmotic dilators** are devices inserted into the cervix, that gradually expand as they absorb fluid, opening the cervical canal. **Surgery** - *Cervical dilatation and suction* of the contents of the uterus (usually up to 14 weeks) - *Cervical dilatation and evacuation* using forceps (between 14 and 24 weeks) Rhesus-negative women having a surgical TOP should have anti-D prophylaxis. The NICE guidelines say it should be considered in women less than 10 weeks gestation.

Answer 274

- Anaemia - Polyhydramnios - Hypertension - Malpresentation - Spontaneous preterm birth - Instrumental delivery or caesarean - Postpartum haemorrhage

Answer 275

- Prematurity/ Miscarriage/ Stillbirth - Fetal growth restriction - Twin-twin transfusion syndrome - Twin anaemia polycythemia sequence - Congenital abnormalities

Answer 276

"Shared Placenta but not shared blood supply" - One fetus (the recipient) may receive the majority of the blood from the placenta, while the other fetus (the donor) is starved of blood. - The recipient gets the majority of the blood, and can become fluid overloaded, with heart failure and polyhydramnios. - The donor has growth restriction, anemia and oligohydramnios. There will be a discrepancy between the size of the fetuses. **Women with twin-twin transfusion syndrome need to be referred to a tertiary specialist fetal medicine centre. In severe cases, laser treatment may be used to destroy the connection between the two blood supplies.**

Answer 277

One twin becomes anaemic whilst the other develops polycythaemia (raised haemoglobin).

Answer 278

Complication of labour when the muscle layer of the uterus myometrium ruptures

Answer 386

The uterine serosa (**Perimetrium**) surrounding the uterus remains intact

Answer 387

Serosa ruptures along with the myometrium and the contents of the uterus are released into the peritoneal cavity

Answer 388

**Haemorrhage** Baby may be released into the peritoneal cavity Fetal and Maternal Morbidity

Answer 389

**Previous C Section** - The scar on the uterus becomes a point of weakness, and may rupture with excessive pressure. It is extremely rare for uterine rupture to occur in a patient that is giving birth for the first time. **Other Risk Factors** - Vaginal birth after caesarean (VBAC) - Previous uterine surgery - Increased BMI/ Age - High parity - Induction of labour - Use of oxytocin to stimulate contractions

Answer 390

Answer 398

Regular painful contraction and cervical dilatation, without rupture of the amniotic sac.

Answer 399

**Less than 30 Weeks** - Clinical **More than 30 Weeks** 1st Choice) TV USS (Cervical Length <15mm) Alternative) Fetal Fibronectin <50 = Negative for Preterm Fetal fibronectin is an alternative test to vaginal ultrasound. Fetal fibronectin is the “glue” between the chorion and the uterus, and is found in the vagina during labour. A result of less than 50 ng/ml is considered negative, and indicates that preterm labour is unlikely.

Answer 400

Fetal monitoring - CTG or intermittent auscultation Tocolysis with nifedipine - Nifedipine is a calcium channel blocker that suppresses labour Maternal corticosteroid - Offered before 35 weeks gestation to reduce neonatal morbidity and mortality IV magnesium sulphate - Before 34 weeks gestation and helps protect the baby’s brain Delayed cord clamping or cord milking - Increase the circulating blood volume and haemoglobin in the baby at birth

Answer 401

Stop uterine contractions

Answer 402

**Nifedipine**, a calcium channel blocker, is the medication of choice for tocolysis. **Atosiban** is an oxytocin receptor antagonist that can be used as an alternative when nifedipine is contraindicated.

Answer 403

Between 24 and 33+6 weeks gestation in pre-term labour to delay delivery and buy time for fetal development

Answer 404

Corticosteroids helps to develop the fetal lungs and reduce respiratory distress syndrome after delivery. - **IM dexamethasone two doses 24hrs apart**

Answer 405

IV magnesium sulfate helps **protect the fetal brain during premature delivery. It reduces the risk and severity of cerebral palsy**. Magnesium sulphate is given within 24 hours of delivery of preterm babies or less than 34 weeks gestation. It is given as a bolus, followed by an infusion for up to 24 hours or until birth.

Answer 406

Answer 409

The amniotic sac has ruptured before the onset of labour and before 37 weeks gestation (preterm).

Answer 410

The amniotic sac ruptures more than 18 hours before delivery.

Answer 411

When the umbilical cord descends below the presenting part of the foetus and into the vagina through the cervix

Answer 412

Fetal hypoxia

Answer 413

**Abnormal lie after 37 weeks** - this provides space for the cord to prolapse below the presenting part **Other** Multiparity Polyhydramnios Artificial rupture of membranes In a cephalic lie the head descends into the pelvis without room for the umbilical cord

Answer 414

CTG = Fetal Distress Vaginal Exam Gold = Speculum examination

Answer 415

**Emergency caesarean w/ Tocolytics** A normal vaginal delivery has a high risk of cord compression and significant hypoxia to the baby. **DONT PUSH THE CORD BACK IN** The cord should be kept warm and wet and have minimal handling whilst waiting for delivery (handling causes vasospasm). **Prevent Cord Compression** When the baby is compressing a prolapsed cord, the **presenting part can be pushed upwards** to prevent it compressing the cord. The woman can lie in the left lateral position (with a pillow under the hip) or the **knee-chest position** (on all fours), using gravity to draw the fetus away from the pelvis and reduce compression on the cord.

Answer 416

Answer 422

**Subgleal haemorrhage** - most dangerous Intracranial haemorrhage Skull fracture Spinal cord injury

Answer 423

Femoral nerve (knee and leg) - Compressed against the **inguinal canal** during a forceps delivery. - Px = weakness of knee extension, loss of the patella reflex and numbness of the anterior thigh and medial lower leg. Obturator nerve (hip and thigh) - Compressed by forceps during instrumental delivery or by the fetal head during normal delivery - Px = weakness of hip adduction and rotation, and numbness of the medial thigh.

Answer 424

Labour for the first time

Answer 425

Power (uterine contractions) Passenger (size, presentation and position of the baby) Passage (the shape and size of the pelvis and soft tissues)

Answer 426

Latent phase <3cm dilation of the cervix - Progresses at around 0.5cm per hour - There are irregular contractions. Active phase <7cm dilation of the cervix - Progresses at around 1cm per hour - There are regular contractions. Transition phase <10cm dilation of the cervix - Progresses at around 1cm per hour - There are strong and regular contractions.

Answer 427

Less than 2cm of cervical dilatation in 4 hours Slowing of progress in a multiparous women

Answer 428

1st stage of labour - Cervical dilation - measured every 4 hours vaginal examination - Descent of fetal head - in relation to ischial spines - Maternal BP, HR, temp and UO - Fetal heart rate - Frequency of contractions - Status of membranes - presence of liquor - if stained with blood or meconium - Drugs and fluid that may have been given Uterine contractions are measure in contractions per 10 minutes. When the midwife says “she is contracting 2 in 10”, it means she is having 2 uterine contractions in a 10 minute period. There are two lines on the partogram that indicate when labour may not be progressing adequately. These are labelled “alert” and “action”. The dilation of the cervix is plotted against the duration of labour (time). When it takes too long for the cervix to dilate, the readings will cross to the right of the alert and action lines. **Crossing the alert line is an indication for amniotomy** (artificially rupturing the membranes) and a repeat examination in 2 hours. **Crossing the action line means care needs to be escalated to obstetric-led care** and senior decision-makers for appropriate action.

Answer 429

from 10cm dilation to delivery of baby

Answer 430

**Power** - strength of uterine contractions - oxytocin infusion can be used to stimulate the uterus **Passenger** - size (shoulder dystonia) , attitude (posture, back rounded, limbs flexed), lie (longitudinal, transverse, oblique) , presentation (Cephalic, shoulder or breech) **Passage** - size and shape of passageway, mainly pelvis

Answer 431

2 hours for nulliparous women 1 hour for multiparous women

Answer 432

Answer 433

The third stage of labour is from delivery of the baby to delivery of the placenta

Answer 434

- More than 30 minutes with active management (IM oxytocin and controlled cord traction) - More than 60 minutes with physiological management

Answer 435

**Amniotomy**, also known as artificial rupture of membranes (ARM) for women with intact membranes **Oxytocin infusion** - aim for 4-5 contraction every 10mins **Instrumental delivery** **Caesarean section**

Answer 436

Fetal compromise- no opportunity to recover between contractions

Answer 437

Difficulty for the placenta to separate from the uterine wall due to implantation

Answer 438

Superficial Myometrial Placenta Implantation

Answer 439

Deep Myometrial placenta Implantation

Answer 440

Placental implantation beyond the myometrium and perimetrium to other organs

Answer 441

Previous placenta accreta Previous endometrial curettage Previous caesarean section Multigravida Increased maternal age Low-lying placenta or placenta praevia

Answer 442

Placenta accreta does not typically cause any symptoms during pregnancy. It can **present with bleeding (antepartum haemorrhage) in the third trimester.** It may be **diagnosed on antenatal ultrasound scans**, and particular attention is given to women with a previous placenta accreta or caesarean during scanning. It may be diagnosed at birth, when it becomes difficult to deliver the placenta. It is a cause of **significant postpartum haemorrhage.**

Answer 443

Antenatal USS - This allows planning for birth Antenatal MRI - Assess the depth and width of the invasion. A specialist MDT should manage women with placenta accreta. Patients may require additional management at birth due to the risk of bleeding and difficulty separating the placenta. This may include: - Complex uterine surgery - Blood transfusions - Intensive care for the mother - Neonatal intensive care Delivery is planned between 35 to 36 + 6 weeks gestation to reduce the risk of spontaneous labour and delivery. **Antenatal steroids are given to mature the fetal lungs before delivery**. The options during caesarean are: - **Hysterectomy with the placenta remaining in the uterus (recommended)** - Uterus preserving surgery, with resection of part of the myometrium along with the placenta - Expectant management, leaving the placenta in place to be reabsorbed over time Expectant management comes with significant risks, particularly bleeding and infection. The RCOG guideline (2018) suggests that if placenta accreta is seen when opening the abdomen for an elective caesarean section, the abdomen can be closed and delivery delayed whilst specialist services are put in place. If placenta accreta is discovered after delivery of the baby, a hysterectomy is recommended.

Answer 444

Placenta attached to the lower portion of the uterus, lower than the presenting part of the fetus

Answer 445

Answer 450

Asymptomatic Painless antepartum haemorrhage Bleeding later in pregnancy around or after 36 weeks

Answer 451

**20 week anomaly scan** used to assess the position of placenta and diagnosis

Answer 452

1) Low Lying placenta @20 wks Anomaly scan? 2) Repeat USS ..... - 32 weeks gestation - 36 weeks gestation (if present on the 32-week scan, to guide decisions about delivery) **Corticosteroids are given between 34 and 35 + 6 weeks gestation to mature the fetal lungs**, given the risk of preterm delivery. Planned delivery is considered between 36 and 37 weeks gestation. It is planned early to reduce the risk of spontaneous labour and bleeding. **Planned cesarean section is required with placenta praevia and low-lying placenta (<20mm from the internal os).** Depending on the position of the placenta and fetus, different incisions may be made in the skin and uterus, for example, vertical incisions. Ultrasound may be around the time of the procedure to locate the placenta. Emergency caesarean section may be required with premature labour or antenatal bleeding. The main complication of placenta praevia is haemorrhage before, during and after delivery. When this occurs, urgent management is required and may involve: - Emergency caesarean section - Blood transfusions - Intrauterine balloon tamponade - Uterine artery occlusion - Emergency hysterectomy

Answer 453

Placenta separates from the wall of the uterus during pregnancy. The site of attachment can bleed extensively after the placenta separates. **Placental abruption is a significant cause of antepartum haemorrhage.**

Answer 454

Previous placental abruption Pre-eclampsia Bleeding early in pregnancy Trauma (consider domestic violence) Multiple pregnancy Fetal growth restriction Multigravida Increased maternal age Smoking Cocaine or amphetamine use

Answer 455

Sudden severe continuous abdominal pain Vaginal bleeding (antepartum haemorrhage) Shock (hypotension and tachycardia) Abnormalities on the CTG indicating fetal distress Characteristic **“woody” abdomen** on palpation, suggesting a large haemorrhage

Answer 456

1) Spotting 2) Minor haemorrhage: 50ml blood loss 3) Major haemorrhage: up to 1000ml blood loss 4) Massive haemorrhage: >1000 ml blood loss, or signs of shock

Answer 457

Closed Cervical OS - Bleeding that occurs remains within the uterine cavity. The severity of bleeding can be significantly underestimated with concealed haemorrhage.

Answer 458

**Fetus alive and < 36 weeks** Fetal distres = immediate caesarean No fetal distress = observe closely, steroids, no tocolysis, threshold to deliver depends on gestation **Fetus alive and > 36 weeks** Fetal distress: immediate caesarean No fetal distress: deliver vaginally **Fetus dead** induce vaginal delivery

Answer 459

Fetal vessels are within the fetal membranes (chorioamniotic membranes) and travel across the internal cervical os. The fetal membranes surround the amniotic cavity and developing fetus. The fetal vessels consist of the two umbilical arteries and single umbilical vein. Vessels placed over the internal cervical os before the foetus

Answer 460

Exposed fetal vessels outside the protection of the umbilical cord or the placenta. The fetal vessels travel through the chorioamniotic membranes, and pass across the internal cervical os (the inner opening of the cervix). **These exposed vessels are prone to bleeding, particularly when the membranes are ruptured during labour and at birth**. This can lead to dramatic fetal blood loss and death.

Answer 461

**Type I vasa praevia** - the fetal vessels are exposed as a velamentous umbilical cord **Type II vasa praevia** - the fetal vessels are exposed as they travel to an accessory placental lobe

Answer 462

Answer 483

1) Estimated fetal weight (EFW) 2) Fetal abdominal circumference (AC) Customised growth charts used to assess the size of the foetus **based on the mothers ehtnicity/ weight/height and parity**

Answer 484

<3rd centile for gestational age

Answer 485

**Constitutionally small** - matching the mother and others in the family, and growing appropriately on the growth chart **Fetal growth restriction (FGR)**, also known as intrauterine growth restriction **(IUGR)**

Answer 486

small fetus (or a fetus that is not growing as expected) due to a pathology **reducing the amount of nutrients and oxygen being delivered to the fetus through the placenta.**

Answer 487

**Placenta mediated growth restriction** - Idiopathic - Pre-eclampsia - Maternal smoking - Maternal alcohol - Anaemia - Malnutrition - Infection - Maternal health conditions **Non-placenta medicated growth restriction** - Genetic abnormalities - Structural abnormalities - Fetal infection - Errors of metabolism

Answer 488

- Reduced amniotic fluid volume - Abnormal Doppler studies - Reduced fetal movements - Abnormal CTGs

Answer 489

**Short Term** Fetal death or stillbirth Birth asphyxia Neonatal hypothermia Neonatal hypoglycaemia **Long Term** Cardiovascular disease, particularly hypertension Type 2 diabetes Obesity Mood and behavioural problems

Answer 490

Previous SGA baby Obesity Smoking Diabetes Existing hypertension Pre-eclampsia Older mother (over 35 years) Multiple pregnancy Low pregnancy‑associated plasma protein‑A (PAPPA) Antepartum haemorrhage Antiphospholipid syndrome

Answer 491

**Risk Factors** Risk of Pre-Eclampsia = Aspirin Treating modifiable risk factors Serial growth scans to monitor growth Early delivery for static growth **Investigations** Blood pressure and urine dipstick for pre-eclampsia **Uterine artery doppler** scanning Detailed fetal anatomy scan by fetal medicine **Karyotyping** for chromosomal abnormalities **Testing for infections** (e.g. toxoplasmosis, cytomegalovirus, syphilis and malaria) **Early Delivery** Early delivery is considered when growth is static on the growth charts, or other problems are identified (e.g. abnormal Doppler results). This reduces the risk of stillbirth. Corticosteroids are given when delivery is planned early, particularly when delivered by caesarean section.

Answer 500

Bacterial vaginosis can increase the risk of catching sexually transmitted infections, including chlamydia, gonorrhoea and HIV. It is also associated with several complications in pregnant women: Miscarriage Preterm delivery Premature rupture of membranes Chorioamnionitis Low birth weight Postpartum endometritis

Answer 501

--> Increased oestrogen (higher in pregnancy, lower pre-puberty and post-menopause) --> Poorly controlled diabetes --> Immunosuppression (e.g. using corticosteroids) --> Broad-spectrum antibiotics

Answer 502

Thick, white discharge that does not typically smell Vulval and vaginal itching, irritation or discomfort

Answer 503

--> Testing the vaginal pH using a swab and pH paper can be helpful in differentiating between bacterial vaginosis and trichomonas (pH > 4.5) and candidiasis (pH < 4.5). --> A charcoal swab with microscopy can confirm the diagnosis.

Answer 504

A single dose of intravaginal clotrimazole cream (5g of 10% cream) at night A single dose of clotrimazole pessary (500mg) at night Three doses of clotrimazole pessaries (200mg) over three nights A single dose of fluconazole (150mg)

Answer 508

--> The diagnosis can be confirmed with a standard charcoal swab with microscopy (examination under a microscope). --> Swabs should be taken from the posterior fornix of the vagina (behind the cervix) in women. A self-taken low vaginal swab may be used as an alternative. --> A urethral swab or first-catch urine is used in men.

Answer 509

Patients should be referred to a genitourinary medicine (GUM) specialist service for diagnosis, treatment and contact tracing. Treatment is with metronidazole.

Answer 510

Gram-negative bacteria

Answer 511

--> young --> sexually active --> multiple partners

Answer 512

National chlamydia screening programme --> screens sexually active person under 25 years annually --> when change of sexual partner --> postivie test - prompts re-test after 3 months after treatment

Answer 513

Chlamydia Gonorrhoea Syphilis (blood test) HIV (blood test)

Answer 514

The majority of cases of chlamydia in women are asymptomatic. Consider chlamydia in women that are sexually active and present with: --> Abnormal vaginal discharge --> Pelvic pain --> Abnormal vaginal bleeding (intermenstrual or postcoital) --> Painful sex (dyspareunia) --> Painful urination (dysuria) Consider chlamydia in men that are sexually active and present with: --> Urethral discharge or discomfort --> Painful urination (dysuria) --> Epididymo-orchitis --> Reactive arthritis It is worth considering rectal chlamydia and lymphogranuloma venereum in patients presenting with anorectal symptoms, such as discomfort, discharge, bleeding and change in bowel habits.

Answer 515

Pelvic or abdominal tenderness Cervical motion tenderness (cervical excitation) Inflamed cervix (cervicitis) Purulent discharge

Answer 516

Nucleic acid amplification tests (NAAT) are used to diagnose chlamydia. This can involve a: Vulvovaginal swab Endocervical swab First-catch urine sample (in women or men) Urethral swab in men Rectal swab (after anal sex) Pharyngeal swab (after oral sex)

Answer 517

--> First-line for uncomplicated chlamydia infection is doxycycline 100mg twice a day for 7 days. --> Azithromycin/Erythromycin/amoxicillin in pregnant or breastfeeding as doxycycline cant be taken in preg

Answer 518

Pelvic inflammatory disease Chronic pelvic pain Infertility Ectopic pregnancy Epididymo-orchitis Conjunctivitis Lymphogranuloma venereum Reactive arthritis Pregnancy-related complications include: Preterm delivery Premature rupture of membranes Low birth weight Postpartum endometritis

Answer 519

--> condition affecting the lymphoid tissue around the site of infection with chlamydia - common in men who have sex with men and three stages

Answer 520

The primary stage involves a painless ulcer (primary lesion). This typically occurs on the penis in men, vaginal wall in women or rectum after anal sex. The secondary stage involves lymphadenitis. This is swelling, inflammation and pain in the lymph nodes infected with the bacteria. The inguinal or femoral lymph nodes may be affected. The tertiary stage involves inflammation of the rectum (proctitis) and anus. Proctocolitis leads to anal pain, change in bowel habit, tenesmus and discharge. Tenesmus is a feeling of needing to empty the bowels, even after completing a bowel motion.

Answer 521

--> Doxycycline 100mg twice daily for 21 days --> erythromycin and azithromycin are alternatives

Answer 522

--> Treponema pallidum --> Spirochete - spiral shaped bacteria

Answer 523

--> Oral, vaginal or anal sex involving direct contact with an infected area --> Vertical transmission from mother to baby during pregnancy --> Intravenous drug use --> Blood transfusions and other transplants (although this is rare due to screening of blood products)

Answer 524

Primary syphilis involves a painless ulcer called a chancre at the original site of infection (usually on the genitals). Secondary syphilis involves systemic symptoms, particularly of the skin and mucous membranes. These symptoms can resolve after 3 – 12 weeks and the patient can enter the latent stage. Latent syphilis occurs after the secondary stage of syphilis, where symptoms disappear and the patient becomes asymptomatic despite still being infected. Early latent syphilis occurs within two years of the initial infection, and late latent syphilis occurs from two years after the initial infection onwards. Tertiary syphilis can occur many years after the initial infection and affect many organs of the body, particularly with the development of gummas and cardiovascular and neurological complications. Neurosyphilis occurs if the infection involves the central nervous system, presenting with neurological symptoms.

Answer 525

Primary syphilis can present with: A painless genital ulcer (chancre). This tends to resolve over 3 – 8 weeks. Local lymphadenopathy Secondary syphilis typically starts after the chancre has healed, with symptoms of: Maculopapular rash Condylomata lata (grey wart-like lesions around the genitals and anus) Low-grade fever Lymphadenopathy Alopecia (localised hair loss) Oral lesions Tertiary syphilis can present with several symptoms depending on the affected organs. Key features to be aware of are: Gummatous lesions (gummas are granulomatous lesions that can affect the skin, organs and bones) Aortic aneurysms Neurosyphilis Neurosyphilis can occur at any stage if the infection reaches the central nervous system, and present with symptoms of: Headache Altered behaviour Dementia Tabes dorsalis (demyelination affecting the spinal cord posterior columns) Ocular syphilis (affecting the eyes) Paralysis Sensory impairment

Answer 526

Antibody testing for antibodies to the T. pallidum bacteria can be used as a screening test for syphilis. Patients with suspected syphilis or positive antibodies should be referred to a specialist GUM centre for further testing. Samples from sites of infection can be tested to confirm the presence of T. pallidum with: Dark field microscopy Polymerase chain reaction (PCR)

Answer 527

All patients should be managed and followed up by a specialist service, such as GUM. As with all sexually transmitted infections, patients need: Full screening for other STIs Advice about avoiding sexual activity until treated Contact tracing Prevention of future infections A single deep intramuscular dose of benzathine benzylpenicillin (penicillin) is the standard treatment for syphilis.

Answer 528

HSV - HSV-2

Answer 529

virus becomes latent in the associated sensory nerve ganglia. Typically this is the trigeminal nerve ganglion with cold sores and the sacral nerve ganglia with genital herpes.

Answer 530

Cold sores- often contracted initially in childhood and remain dormant in the trigememinal nerve ganglion and reactivate as cold sores.

Answer 531

genital herpes - STI can cause lesions in the mouth

Answer 532

Patients affected by herpes simplex may display no symptoms, or develop symptoms months or years after an initial infection when the latent virus is reactivated. The symptoms of an initial infection with genital herpes usually appear within two weeks. The initial episode is often the most severe, and recurrent episodes are milder. Signs and symptoms include: Ulcers or blistering lesions affecting the genital area Neuropathic type pain (tingling, burning or shooting) Flu-like symptoms (e.g. fatigue and headaches) Dysuria (painful urination) Inguinal lymphadenopathy Symptoms can last three weeks in a primary infection. Recurrent episodes are usually milder and resolve more quickly.

Answer 533

The diagnosis can be made clinically based on the history and examination findings. A viral PCR swab from a lesion can confirm the diagnosis and causative organism.

Answer 534

Aciclovir is used to treat genital herpes. There are various aciclovir regimes listed in the BNF, depending on the individual circumstances. Alternatives are valaciclovir and famciclovir. Additional measures, including to manage the symptoms include: Paracetamol Topical lidocaine 2% gel (e.g. Instillagel) Cleaning with warm salt water Topical vaseline Additional oral fluids Wear loose clothing Avoid intercourse with symptoms

Answer 535

--> risk of neonatal herpes simplex infection - high morbidity and high mortality

Answer 536

Aciclovir during the initial infection followed immediately by regular prophylactic aciclovir. Caesarean section is recommended in all cases to reduce the risk of neonatal infection

Answer 537

--> STI --> Gram-negative diplococcus --> Infects mucous membranes with a columnar epithelium e.g urethra, rectum, conjunctiva, pharynx --> spreads via mucous secretions from infected areas

Answer 538

--> more likley to be symptomatic comapred to chlamydia infection Females --> odourless purulent discharge - green or yellow --> dysuria --> pelvic pain Males --> ouderless purulent discahrge possibily green or yellow --> dysuria --> testicular pain - epididymo-orchititis Prostatitis and conjunctivitis

Answer 539

NAAT - nucleic acid amplification testing - detects the RNA or NA of gonorrhoea --> first-catch urine sample --> rectal and pharyngeal swabs im all MSM --> Standard charcoal endocervical/ urethral swab for microscopy, culture and abx sensitivities. high rates of abx resistance

Answer 540

A single dose of intramuscular ceftriaxone 1g if the sensitivities are NOT known A single dose of oral ciprofloxacin 500mg if the sensitivities ARE known --> follow up test of cure
