reproductive Flashcards
1
Q
aetiology of torsion of testis
A
- Children/young adults – commonest in neonatal period and around puberty
- Undescended testis
2
Q
clinical features of torsion of testis
A
- Sudden onset severe painful testis – triggered by activity e.g. playing sports
- Vomiting
- Abdo pain
- Testicular exam: Red, tender, firm, swollen testis
- Opposite testis may lie horizontally (Angell’s sign)
- Abnormal rotation so that epididymis is not in posterior position
- Elevated (retracted) testicle
- Bell clapper deformity: absence of fixation of the tesicle posteriorly to the tunica vaginalis
- Lack of cremasteric reflex: testicle will not contract if torsion is present
- Prehn’s sign – worse pain when elevation of the testicles
3
Q
investigation for torsion of testis
A
doppler USS - only if in double, otherwise straight to surgery
urine dip to check not infeective
4
Q

A
epididymitis - pain relieved when lifted
epididymo-orchitis hydrocele/varicocele - shine light testicular cancer inguinal hernia renal colic HSP acute appendicitis
5
Q
management of torsion of testis?
A
immediate referal to surgery - 6 our windwo before ischaemia is irrevesible
- surgical scrotal exploration
- untwisting of the testicle and orchiplexy (fixing both testicles to preventing further episodes)
- orchiectomy if necrosis
6

9
Q
investigation for ectopic pregnancy
A
pregnancy test - +Ve
TV USS - establish the location of the pregnancy, the presence of adnexal massess or freee fluid
serum hCG at 0 and 48 hour
- a rise > 63% suggests intrauterine pregnancy
- a suboptimal rise is suspicious of an ectopic pregnancy
- decrease of > 50% = likely failing pregnancy
10
Q
management of rupture of ectopic pregnancy
A
resuss A-E assessment
followed by salpingectomy
11
Q
when will you use expectant management of ectopic pregnancy
A
- stable
- asymptomatic
- hCG < 1500 iU
• EP <3cm and no fetal cardiac activity on TV USS
• No haemoperitoneum on TV USS
• Fully understand symptoms and implications of EP.
• Language should not be a barrier to understanding or communicating the problem to a third party (e.g. ambulance).
• Live in close proximity to the hospital and have support at home.
• You deem the patient will not default on follow up.
• Requires serum hCG initially every 48 hours until repeated fall in level, then weekly until <15IU.
12
Q
when will you use medical management of ectopic pregnancy
A
failed expectant management
Methotrexate is given IM as a single dose of 50mg/m2.
• Criteria:
• Follow up possible
• Unruptured
• Adnexal mass <35mm
• No visible heart beat
• No significant pain
• hCG level <1500 IU/l
• Confirmed absence of intrauterine pregnancy on USS
• hCG levels should be measured at 4 and 7 days and another dose of methotrexate given (up to 25% of cases) if the in hCG is <15% on days 4-7
• Sexual intercourse should be avoided during treatment and reliable contraception used for 3 months after as meth
otrexate is teratogenic.
13
Q
when will you use surgical management of ectopic pregnancy
A
when medical management fails
laparoscopy salpingectomy if - hemodynamically unstable - unable to return for follow up - significant pain - adnexal mass > 35 mm - foetal heartbeat visible on USS - hcg level > 5000 give methotrexate post-surgery

2-12 days
| spread by skin to skin contact
26
which herpes subtype causes genital herpes lesions
HSV-2
27
which herpes subtype causes oral herpes lesions
HSV-1
28
pathophysiology of genital herpes
HSV-2 spread via skin to skin spread
HSV-2 then infect the host local tissue, it then ascends via the sensory neuron to the sensory ganglion where it remain din latent state
the virus might then periodically reactivates, traveling down the axon and into the basal skin layers
29
clinical features of primary genital herpes
usually the most severe and often result in
- flu-like illness (muscle aches, malaise, headache)
- women - fever, neuralgia, dysuria, constipation
- discharge
- inguinal lymphadenopathy
- vulvitis and pain
- if no pain - consider syphilis
- small, characteristic vesicles and ulcers on the vulva (painful/tingling) - painful enough to cause urinary retention --> progress to ulceration --> crusted lesion
- typcially lasts around 3 weeks
30
clinical features of secondary genital herpes
recurrent attacks result from reactivation of latent virus in the sacral ganglia - usually short and less severe - lesions and pain
- can be triggered by stress, sex, menstruation
31

clinical and history
viral PCR of versicle fluid = gold standard
32
management of genital herpes
* Reassure patient that recurrences are mild and short lived- saline baths and topical anaesthetic gels/creams/ice packs may help self-management
* Abstain from sexual intercourse until follow up/lesions have cleared
* Treatment with oral acyclovir may be effective if given within 5 days of onset of symptoms
in pregnancy
- if labour is within 6 weeks of primary infection then delivery by CS
33
complications of genital herpes

meningitis
sacral radiclopathy
transverse myelitis
disseminated infection

```
Implications in pregnancy:

• Preterm labour.
• Neonatal risks:
• Transmission rate from vaginal delivery during primary maternal infection may be as high as 50% but is relatively uncommon during a recurrent attack (<5%).
• Neonatal herpes appears during the first two weeks of life
34
what is the advise for those who is HIV +ve but want to conceive
* Adviced to wait till viral load is low to conceive
* Mother = self-insemination

61
what is erectile dysfunction
persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance
62
physiology of an erection
* Erection occurs due a neurovascular mechanism
* control of the smooth muscle tissue of the corpora cavernosa by the autonomic system
* Swelling is due to a reduction in the alpha-sympathetic tonus of the cavernous tissue permitting influx of arterial blood, and to decreased venous flow from compression of the subalbugineal venous network against the tunica albuginea of the corpus cavernosurn
* Once this obstruction to the venous return has been achieved, the arterial flow in the corpora cavernosa decreases but persists
* Rigidity is due to an increase in intracavernous arterial pressure simultaneous with contraction of the perineal muscles (ischiocavernosus) under the somatic control of the pudendal nerve
