Sheehan’s Syndrome
Postpartum hypopituitarism
3 Fs Failure of lactation, fatigue, failure to resume menstruation
Asherman’s Syndrome
Intrauterine adhesions
1-2% of 2nd amenorrhoea.
Frequently after DandC.
Ix- hysteroscopy, hormone studies Normal
D and C
Dilation and Curettage
Opening the cervix and removing contents of the uterus
Done after miscarriage usually if over 10 weeks old.
Cervical Smear Testing
Routine every 3 or 5 years depending on age
Borderline change - repeat in 6-12 months
Mild Dyskaryosis (CIN1) - Colposcopy or repeat in 6 months
Mod Dyskaryosis (CIN2)- Refer for colposcopy
Severe Dyskaryosis (CIN3) - colposcopy
Suspected invasive CA - Urgent colposcopy
Inadequate - repeat, after 3x then colposcopy
Leiomyoma (Fibroids)
Benign Smooth muscle tumours of the uterus
20-50% of women over 30 yrs
Most are aymptomatic and only 10-20% need tx
Sx- abdo cramps, menorrhagia.
Tx - Meds or surgery
Pharmacological Tx of fibroids
NSAIDS - mefanamic acid reduce menstrual blood loss
Antifibrinolytic agents - tranexamic acid do the same
COCP
Danazol
GnRH agonists
Surgical Tx of fibroids
Myomectomy
Hysteroscopic endometrial ablation
Total hyseterectomy
Uterine artery embolisation
Adenomyosis
Ectopic endometrial tissue within the myometrium
Endometrial glands 1 high power field deeper than E-M junction
Sx- heavy freq periods, dysmenorrhoea, pelvic pain
Ruptured Ovarian Cyst
History of mild trauma after fall or intercourse.
Mild chronic lower abdo discomfort that suddenly worsen
USS- fluid in space between falopian tubes and ovaries
Red Degeneration of Fibroid
5-10& of pregnant women with myomas
Acute significant localised abdo pain.Vomiting and fever
USS- mixed echodense or echolucent appearance.
Hyperemesis Gravidarum
Intractable vomiting in early pregnancy Ix- raised haematocrit, low Na, low K, low urea, high creat high AST. high free t4, low TSH Urine - ketonuira Tx- Promethazine, ginger
Acute fatty liver of pregnancy
Rare life threatening in 3rd trimester.
Disordered metabolism of fatty acids causing liver failure
Raised AST
Tx- prompt delivery of the baby.
Placental Abruption
Premature separation of the placenta from the uterus
Present with bleeding (some have concealed bleeding), tender tense uterus, foetal distress
Should be considered in bleeding 2nd half of pregnancy
Placenta Praevia
Implantation of the placenta over the internal cervical os
Painless vaginal bleeding,
Vasa Praevia
Foetal vessels crossing or close to inner cervical os
Antepartum haemorrhage immediately after artifical rupture.
Bleeding in 1st Trimester
Spontaneous abortion
Ectopic pregancy
Hydatidiform mole
Bleeding in 2nd Trimester
Spontaneous abortion
Hydatidiform mole
Placental abruption
Bleeding in 3rd Trimester
Placental abruption
Bloody show
Placenta praevia
Vasa praevia
Hydatidiform mole
Gestational trophoblastic disease
Non viable fertilised egg implants in the uterus
Antenatal USS times
11-14 weeks for dating and nuchal translucency
18 weeks is the anomaly scan.
Amniocentesis
Measure alpha fetoprotein at 16 weeks to detect neural tube defects (1% risk of foetal loss)
Combined Test
Between 10-13 weeks to screen for Downs.
Includes Nuchal translucency, free B-HCG, pregnancy associated plasma protein, women’s age
If high risk then offered CVS (if less than 13 weeks) or amniocentesis (if beyond 15 weeks)
Uterine Prolapse
1st degree - Cervix remains within vagina
2nd deg - Cervix protrudes through introitus
3rd deg - Uterus lies entirely outside introitus
Should be examined using Sims’s speculum.
Tx- pelvic floor exercises, ring pessary
Dysfunctional uterine bleeding
Abnormal uterine bleeding in the absence of organic dx
Heavy menstrual bleeding around menarche and perimenopause
Tx - Levonorgestrel-releaseing IU system, tranexamic acid, norethisterone.
Bartholin’s glands
Pair of peas sized glands whose secretions maintain moisture of the vestibular surface of the vagina
At 4 and 8 o’clock position
Cyst - rapid onset painful lump size of a walnut.
Pre-eclampsia
Pregnancy induced hypertension in the 2nd half (after 20 weeks) associated with proteinuria +/- oedema
RF- age >40, nulliparity, FH, BMI over 30, HTN, Renal disease.
Only cure is terminate pregnancy and deliver the placenta.
Eclampsia
Occurrence of one or convulsions during pre-eclampsia
