Q

A 35-year-old woman attends your GP practice, she is known to you as she is having trouble conceiving and has been trying for a baby for the past 8 months. She comes today as she has noticed her periods have been getting heavier over the past year or so. She thought it was due to her getting older, but now her periods have become unmanageable and she has had episodes of flooding. After taking a full history you examine her abdomen, which is soft, non-tender, but you can palpate a supra-pubic mass.

What is the mostly likely diagnosis?

A

fibroids

foudn 
intra mural - myometrium 
pedunculate - a stalk 
submucosal - below endometrium 
subserosal - below perimetrium

Pregnant women with history of fibroid presenting with severe abdominal pain + low grade fever
Rapid growth of fibroids during pregnancy and it outgrows its blood supply
Ischaemic & necrosis of fibroid
Most likely to occur during 2nd and 3rd trimester of pregnancy
Tx: Supportive management

Q

A 6-month-old child is brought to the surgical clinic because of non descended testes. What is the main structure that determines the descent path of the testicle?

A

The gubernaculum is a ridge of mesenchymal tissue that connects the testis to the inferior aspect of the scrotum. Early in embryonic development the gubernaculum is long and the testis are located on the posterior abdominal wall. During foetal growth the body grows relative to the gubernaculum, with resultant descent of the testis.

Q

menopause characterised by what hormone changes

A

The menopause can either be a natural or iatrogenic process that results in the cessation of oestradiol and progesterone production in the ovaries. Due to this decrease, FSH and LH levels will often increase.

Q

Anteversion refers to the position of the uterus in the coronal plane being tipped forward anteriorly towards the bladder. Conversely, retroversion of the uterus describes the body and fundus leaning posteriorly towards the rectum.

Anteflexion refers to the position of the main body of the uterus relative to the long axis of the cervix. This is easiest to view in the sagittal plane where the fundus of the uterus is anterior relative to the cervix.

Q

in relation to the ovarian artery
common iliac artery and uterine artery where does the ureters go

water under the bridge

A

At the renal pelvis, the ureters are located most posteriorly. As the ureters course inferiorly, they pass posteriorly to the ovarian artery. The ureters cross the pelvic brim anteriorly at the bifurcation of the common iliac arteries. Ureters pass underneath the uterine artery (AKA ‘water under a bridge’). Therefore when ligating the uterine artery, care should be taken to avoid the ureters.

Q

A menopausal woman is started on Hormone Replacement Therapy, which includes oestrogen and progesterone. What are the functions of these hormones in HRT?

A

Oestrogen is for symptomatic relief and progesterone is protective against oestrogenic adverse effects
Many of the menopausal symptoms are due to low oestrogen; therefore the oestrogen in HRT aims for symptomatic relief. However, oestrogen causes endometrial thickening which is a risk for neoplasia, so progesterone is added to HRT to prevent endometrial thickening and any associated risk of malignancy.

Q

With antiretroviral medication for the mother and baby, delivery by caesarean section and discouragement of breastfeeding, the risk of HIV transmission is reduced to less than 2%

what are the factors that reduce transmission

A

maternal antiretroviral therapy
mode of delivery (caesarean section)
neonatal antiretroviral therapy
infant feeding (bottle feeding)\

Screening
NICE guidelines recommend offering HIV screening to all pregnant women

Antiretroviral therapy
all pregnant women should be offered antiretroviral therapy regardless of whether they were taking it previously

Mode of delivery
vaginal delivery is recommended if viral load is less than 50 copies/ml at 36 weeks, otherwise caesarian section is recommended
a zidovudine infusion should be started four hours before beginning the caesarean section

Neonatal antiretroviral therapy
zidovudine is usually administered orally to the neonate if maternal viral load is <50 copies/ml. Otherwise triple ART should be used. Therapy should be continued for 4-6 weeks.

Infant feeding
in the UK all women should be advised not to breast feed

HRT increases the risk of
thrombotic events, such as stroke. This mechanism involves platelet aggregation and is different to atheroma formation, which largely involves cholesterol accumulation. HRT does not increase the risk of thrombocytopaenia or vulval cancer, and the presence of progesterone in the HRT also minimises the risk of developing endometrial cancer.

The risk factors for endometrial cancer are as follows*:
``` obesity nulliparity early menarche late menopause unopposed oestrogen. The addition of a progestogen to oestrogen reduces this risk (e.g. In HRT).

43
main contributor to increase CO in pregnancy
stroke volume During pregnancy, increased stroke volume is the main contributor to the increased cardiac output. This is due to increased plasma volume, secondary to activation of the renin-angiotensin system. The heart rate increases slightly too but this is not as major a contributor. Remember the equation: cardiac output= stroke volume x heart rate. As the stroke volume will increase more in number than the heart rate, it is the major contributor to the increased cardiac output.

Which type of receptor is found on the theca?
LH

A 26-year-old woman presents to her GP with milky discharge from her breasts. Her periods have also become very irregular and she has not menstruated in the past 3 months. On further questioning, she reports not being sexually active since having a miscarriage 7 months ago which required surgical management. On examination, there are no palpable masses in her breasts bilaterally, she demonstrates a small amount of milky white discharge from her left nipple which is collected for microscopy, culture, and sensitivity. She has no focal neurological deficits, cardiac, and respiratory examination is unremarkable, and her abdominal examination is unremarkable. What is the most likely diagnosis?
Prolactinoma causes amenorrhoea in females through inhibiting the secretion of GnRH which in turn results in low levels of oestrogen This patient is presenting with symptoms consistent with a prolactinoma - she has amenorrhoea and galactorrhoea. Male also report gynaecomastia. further investigate she should have a urinary pregnancy test, blood tests to check for bHCG, prolactin, oestradiol, luteinising hormone, and follicle-stimulating hormone. a microprolactinoma is the most likely diagnosis if results come back with nothing or no drug causes and should be confirmed by MRI or CT head. Intraductal papilloma is a benign breast lesion that is a common cause of nipple discharge. The discharge is typically clear or yellow and there is often an underlying lump. It is not associated with changes in menses. As this patient is presenting with amenorrhoea and does not have a breast lump, this is not the most likely answer. Sheehan's syndrome is panhypopituitarism caused by ischaemic necrosis of the pituitary gland from post-partum blood loss/hypovolaemia. The typical scenario for this presentation is a woman presenting following a large post-partum haemorrhage with no galactorrhoea (lack of expected post-partum milk-letdown due to reduced prolactin secretion), amenorrhoea (due to reduced GnRH which causes low levels of oestrogen), hypothyroid symptoms, and hypoadrenalism. The patient in this scenario is reporting galactorrhoea and there is no evidence of a post-partum haemorrhage which should steer the student away from this option.
46
what is ashermnans sydnoem
Asherman's syndrome is a cause of amenorrhoea but does not lead to galactorrhoea. It is caused by intrauterine adhesions, which may occur following dilation and curettage. While this may lead the endometrium to not respond to oestrogen as it normally would (causing the amenorrhoea), it would not cause prolactin secretion leading to lactation.
47
A pregnant woman has her kidney function measured during a routine appointment. Her plasma urea and creatinine are found to be lower than before she was pregnant. Why is this?
increased renal perfusion Plasma urea and creatinine fall during pregnancy due to increased renal perfusion allowing the clearing of these substances from the circulation more, as well as increased plasma volume diluting these substances
48
Physiological changes in pregnancy
Genital changes: increased uterine size (from muscle hypertrophy until 20 weeks, then stretching), cervical ectropion, reduced cervical collagen late in pregnancy (to allow cervical effacement), increased vaginal discharge (due to increased mucus production from vasocongested vagina) Cardiovascular/haemodynamic changes: increased plasma volume disproportionate to increased red cell volume, causing net effect of increased stroke volume and anaemia; increased white cell count, platelets, ESR, cholesterol, fibrinogen; decreased albumin, urea and creatinine Progesterone-related effects (due to muscle relaxation): decreased blood pressure, constipation, ureteral dilation, bladder relaxation, biliary stasis, increased tidal volume
49
hCG levels usually consistently rise until around week 10–12 of your pregnancy, when the levels plateau or even decrease. difference with ectopic
Abnormal elevations in b-hCG, including an increase of less than 53% over 48 hours, is suggestive of a nonviable pregnancy, including ectopic.
