Q

What is the presentation of Syphillis ?

A

Syphillis presents differently over time
1º painless ulcer on penis or vagina, papules can also be seen on the skin (chancre)
2º 6-8 weeks later, lymphadenopathy in the groin/inguinal region, mucosal lesions in the mouth, fever & rash
Then can be latent for a while
3º cerebrospinal problems, cardiovascular symptoms, and gummas present on the skin (lesions which are nodules of granulmoatous tissue)

32
Q

Wha effect will Syphillis have in children ?

A

This can cause congenital Syphillis, miscarriage or stillbirths.

33

Which organism will cause Syphillis ?

A

This is Treponema pallidum

A type of spirochete which can be seen on darkfield microscopy.

34
Q

How can you treat Syphillis ?

A

Penicillin

35
Q

How do you diagnose Syphillis ?

A

Serology - > this is a specialised area .

36
Q

Which other organisms can cause ulceration on the genitals?

A

Chancroid –> haemophilus ducreyi
Granuloma Inguinale/ Donovanosis —> klebsiella granulomatis

These can cause painless ulceration and genital nodules.

37
Q

What kind of problem can Trichomonas vaginalis cause ?

A

An increase in itchy, offensive discharge, thin.

Irritation, dysuria, and vaginal inflammation

38
Q

How can you diagnose a person with trichomonas vaginalis ?

A

High vaginal swab

Vaginal wet preparation : vaginal discharge +/- culture enhancement.

39
Q

How do you treat Trichomonas vaginalis infection ?

A

Metronidazole

Treats anti-protozoan & anaerobic bacteria

40
Q

What is vulvovaginal candidasis and what risk factors can cause it?

A

This is commonly due to a disruption in the normal flora of the vagina this will then cause an overgrowth of the candida
Risk factors : oral contraceptives, pregnancy, obesity, steroids and diabetes

41
Q

What are the symptoms of vulvovaginal candidasis ?

A

Curd like discharge, white, which is profuse

This can be accompanied with itching.

42
Q

How do you diagnose & treat candidasis infection ?

A

Diagnose : high vaginal swab with cultures
Treatment : nystatin/ anole creams or fluconazole Ab.
This can effect the integrity of the cell wall of the fungi.

43
Q

Which organisms can cause bacterial vaginosis ?

A

This is due to perturbed flora in the tract :
Gardnella vaginosis
Anaerobes
Mycoplasma hominids

44
Q

What are the symptoms of bacterial vaginosis ?

A

Scanty , offensive fishy discharge.

45
Q

How do you diagnose bacterial vaginosis ?

A

High vaginal swab with culture
Koh test –> you can smell the fishy odour
Clue cells can be seen —> epithelial cells studded with coccobacilli
There are less lactobacilli in the region and an absence of pus cells?

46
Q

How do you treat bacterial vaginosis ?

A

Tx : with metronidazole

47
Q

What other organisms can cause problems in the repro tract?

A

Scabies –> skin mite which can cause itchiness and soreness
Pubic lice & crabs (phthirus pubis) –> itchiness and soreness.

48
Q

What is pelvic inflammatory disease ?

A

This is due to ascending infections from the endocervix that can present as endometriosis, salpangitis, oophonitis, pelvic peritonitis, and tuburo-ovarian abscess

49
Q

A 
Gonorrhoea 
Chlamydia 
T. Vaginalis 
Bacterial vaginosis --> gardnella, actinomycetes, mycoplasma hominids & anaerobes 
H. Influenzae ,streptococci and CMV
50
Q

What is the Pathophysiolog of PID ?

A

Infection will cause inflammation of the tubal epithelium which can then cause adhesion formation and abscess formation.

51
Q

What complications and problems can arise from PID?

A

Ectopic pregnancy and infertility (as a result of the adhesions)
Adherence to the pelvic side walls
Lymphadenopathy (increase in the number of germinal centres)
Abscess Rupture which can cause sepsis
Chronic pelvic pain
Reiters syndrome
Fitz-Hugh-Curtis syndrome (perihepatitis of the capsule surrounding the liver)

52
Q

What are the risk factors associated with PID?

A 
Unprotected sex 
Low socioeconomic calls 
Age (younger) 
Sexual habits 
Coil --> in placing in the coil and removing the coil an inherent risk is presented to the px. This often results in actinomycetes problems 
Hormonal changes following menses. 
Previous infections and STI
53
Q

What are the clinical features associated with this disease?

A 
Fever >38 
Abdominal pain and deep dysparenuia 
Abnormal vaginal or cervical discharge (itchy,purulent , offensive smelling) 
Abnormal bleeding (post coital , in between menses)
54
Q

What examinations are done to determine PID ?

A

Bimanual examination :
Adnexal tenderness
Cervical motion tenderness

Speculum examination :
Red and inflammed cervix
Purulent discharge.

55
Q

How do you confirm diagnosis of PID ?

A

Urine sampling - dipstick, pregnancy,
Endocervical and high vaginal swab
Blood test to check for markers of inflammation (CRP & wbc)
Other STI screening
NAAT & PCR on samples
Surgical : laparoscope –> visualise and remove adhesions or abscess..

56
Q

What differential diagnosis can be also present as PID?

A

Gynae: ectopic pregnancy (hcg test), endometriosis (presents with relapse remitting pain, ovarian cyst complication (shorter onset of pain which is more severe)
Urinaty : dysuria and frequency
GI tract : IBS & appendicitis (nausea and Vomititng)
Other functional pain (MSK)

57
Q

How do you manage PID?

A

Ab, with severe disease (not responding to Ab, pregnancy, suspected ectopic pregnancy and HIV –> hospitalised)
Analgesic for pain
If px has sepsis –> treat for sepsis

58
Q

What is the tx for PID ?

A

Broad spec antibiotics
Inpx : IM Ceftriaxone, orally : metronidazole & doxycycline
PutPx : IV Ceftriaxone , metronidazole and doxycycline

2 week tx
Follow up in 72 hrs then later in 4 weeks.

59
Q

What are GUM clinics and what are they good at ?

A

Genitourinary medicine

  • maintain anonymity
  • technical know how
  • provide info for safe sex
  • good for contact tracing
  • rapid and efficient tx.
60
Q

What advice would be given to px with STI?

A

Wear loose Undrwear
Safe Sex With Barrier Contraception
Treat partner as well to limit re- infection
Avoid warm moist enviomrents

61
Q

Which two are the most common causative organisms ?

A

N. Gonorrhoea
