Q

what is the commonest cause of respiratory distress in the newborn period? and the biggest risk factor

A

Transient tachypnoea of the newborn.

It is caused by delayed resorption of fluid in the lungs

more common following c-sections (lung fluid not ‘squeezed out’ during labour)

Chest x-ray may show hyperinflation of the lungs and fluid in the horizontal fissure.

Management
observation, supportive care
supplementary oxygen maybe

settles within 1-2 days

Q

what is the normal folic acid intake vs high risk intake and who is high risk?

A

all women should take 400mcg of folic acid until the 12th week of pregnancy
women at higher risk of conceiving a child with a NTD should take 5mg of folic acid from before conception until the 12th week of pregnancy

either partner has a NTD, they have had a previous pregnancy affected by a NTD, or they have a family history of a NTD

the woman is taking antiepileptic drugs or has coeliac disease, diabetes, or thalassaemia trait.

the woman is obese (defined as a body mass index [BMI] of 30 kg/m2 or more).

36
Q

Adjuvant hormonal therapy is offered if tumours are positive for hormone receptors. which are used for who?

A

Tamoxifen is still used in pre- and peri-menopausal women. In post-menopausal women, aromatase inhibitors such as anastrozole

37
Q

how do you decide about whether to revmove lymph nodes in breast cancer surgery?

A

women with no palpable axillary lymphadenopathy at presentation should have a pre-operative axillary ultrasound before their primary surgery
if negative then they should have a sentinel node biopsy to assess the nodal burden

in patients with breast cancer who present with clinically palpable lymphadenopathy, axillary node clearance is indicated at primary surgery

this may lead to arm lymphedema and functional arm impairment

38
Q

who mastectomy vs wide local excision breast cancer

A

Mastectomy Wide Local Excision

Multifocal tumour Solitary lesion
Central tumour Peripheral tumour
Large lesion in small breast Small lesion in large breast
DCIS > 4cm DCIS < 4cm

39
Q

when is radiotherapy used in breast cancer?

A

Whole breast radiotherapy is recommended after a woman has had a wide-local excision as this may reduce the risk of recurrence by around two-thirds.

For women who’ve had a mastectomy radiotherapy is offered for T3-T4 tumours and for those with four or more positive axillary nodes

40
Q

when is biological theraphy used for breast cancer?

A

The most common type of biological therapy used for breast cancer is trastuzumab (Herceptin). It is only useful in the 20-25% of tumours that are HER2 positive.

Trastuzumab cannot be used in patients with a history of heart disorders.

41
Q

when is chemo used fore breast cancer

A

Cytotoxic therapy may be used either prior to surgery (‘neoadjuvanant’ chemotherapy) to downstage a primary lesion or after surgery depending on the stage of the tumour, for example, if there is axillary node disease - FEC-D is used in this situation.

42
Q

A

44
Q

what treatments can be offered for endometriosis before establishing a definitive diagnosis with laparoscopy?

A

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.
GnRH agonists- to induce menopause but you also get menopause sympotoms e.g. hot flushes and risk of osteoperosis

45
Q

investigation for adenomyosis?

A

Transvaginal ultrasound of the pelvis is the first-line investigation for suspected adenomyosis.
MRI and transabdominal ultrasound are alternative investigations where transvaginal ultrasound is not suitable.
The gold standard is to perform a histological examination of the uterus after a hysterectomy. However, this is not usually a suitable way of establishing the diagnosis for obvious reasons.

46
Q

what is the treatment for adenomyosis?

A

NICE recommend the same treatment for adenomyosis as for heavy menstrual bleeding.
When the woman does not want contraception; treatment can be used during menstruation for symptomatic relief, with:
* Tranexamic acid when there is no associated pain (antifibrinolytic – reduces bleeding)
* Mefenamic acid when there is associated pain (NSAID – reduces bleeding and pain)

47
Q

Management when contraception is wanted or acceptable:

A

Mirena coil (first line)
COCP
Cyclical oral progestogens
Progesterone only medications such as the pill, implant or depot injection may also be helpful.

Other options are that may be considered by a specialist include:
GnRH analogues to induce a menopause-like state
Endometrial ablation
Uterine artery embolisation
Hysterectomy

48
Q

what is the most accurate marker of ovarian reserve?

A

Anti-Mullerian hormone can be measured at any time during the cycle and is the most accurate marker of ovarian reserve. It is released by the granulosa cells in the follicles and falls as the eggs are depleted. A high level indicates a good ovarian reserve.

49
Q

Testosterone is necessary for sperm creation. The hypothalamo-pituitary-gonadal axis controls testosterone. Hypogonadotrophic hypogonadism (low LH and FSH resulting in low testosterone), can be due to:

A

pathology of the pituitary gland or hypothalamus
Suppression due to stress, chronic conditions or hyperprolactinaemia
Kallman syndrome which is a condition characterized by delayed or absent puberty and an impaired sense of smell. (genetic condition)

50
Q

what are some causes of Hypergonadotropic Hypogonadism?

A

Hypergonadotrophic hypogonadism is the result of abnormal functioning of the gonads. This could be due to:
* Previous damage to the gonads (e.g. testicular torsion, cancer or infections, such as mumps)
* Congenital absence of the testes or ovaries
-Kleinfelter’s Syndrome (XXY)
-Turner’s Syndrome (XO)

51
Q

how often are women offered a cervical smear test?

A

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

There are some notable exceptions to the program:
-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

52
Q

What is the management based on these smear results?

-Inadequate sample
-HPV negative
-HPV positive with normal cytology
-HPV positive with abnormal cytology

A

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

53
Q

what are the typical examination findings for someone with pelvic inflammatory disease?

A

Examination findings may reveal:
Pelvic tenderness
Cervical motion tenderness (cervical excitation)
Inflamed cervix (cervicitis)
Purulent discharge
Patients may have a fever and other signs of sepsis.

74
Q

Downs syndrome tripple test vs quadruple test

A

The triple test is performed between 14 and 20 weeks gestation. It only involves maternal blood tests:

Beta-HCG – a higher result indicates greater risk
Alpha-fetoprotein (AFP) – a lower result indicates a greater risk
Serum oestriol (female sex hormone) – a lower result indicates a greater risk

75
Q

antenatal downs test

A

Combined Test
The combined test is the first line and the most accurate screening test. It is performed between 11 and 14 weeks gestation and involves combining results from ultrasound and maternal blood tests.

Ultrasound measures nuchal translucency, which is the thickness of the back of the neck of the fetus. Down’s syndrome is one cause of a nuchal thickness greater than 6mm.

Maternal blood tests:

Beta‑human chorionic gonadotrophin (beta-HCG) – a higher result indicates a greater risk
Pregnancy‑associated plasma protein‑A (PAPPA) – a lower result indicates a greater risk

Triple Test
The triple test is performed between 14 and 20 weeks gestation. It only involves maternal blood tests:

Beta-HCG – a higher result indicates greater risk
Alpha-fetoprotein (AFP) – a lower result indicates a greater risk
Serum oestriol (female sex hormone) – a lower result indicates a greater risk

Quadruple Test
The quadruple test is performed between 14 and 20 weeks gestation. It is identical to the triple test, but also includes maternal blood testing for inhibin-A. A higher inhibin-A indicates a greater risk.
