Q

What is the aetiology of bacterial vaginosis?

A

It is caused by an overgrowth of predominantly anaerobic organisms in the vagina. They replace lactobacilli, the dominant bacteria present in the normal vagina. pH increases from 4.5 to as high as 6.
IT IS NOT AN STI

Study These Flashcards
A 
Multiple sexual partners 
Previous history of STIs
Early age of first sexual intercourse
Unprotected sexual encounters
MSM
Female gender 
HIV infection
23
Q

Study These Flashcards
A

Febrile, flu-like prodrome
Tingling neuropathic pain in the genital area/buttocks/legs
Extensive painful blisters/ulcers in the genital area
Tender lymph nodes
Local oedema
Dysuria
Vaginal/urethral discharge

24
Q

What investigations would you perform for HSV infection?

Study These Flashcards
A

Viral culture
Swab from the base of an ulcer for PCR
Serology (can take up to 12 weeks to become positive after the primary infection)

25
What is the differential diagnosis for HSV infection?
Vulvo-vaginal candidiasis Other STIs Skin conditions e.g. scabies, psoriasis or contact dermatitis
26
What is the management for HSV infection?
Referral to the GUM clinic Aciclovir 400mg TDS or valaciclovir 500mg BD for 5 days Supportive management e.g. saline bathing, oral painkillers, topical lidocaine 5%
27
What is the pathology of HPV infection?
There are >100 types of HPV. HPV types 6 and 11 account for >90% of cases Types 16 and 18 are associated with a high risk of neoplastic transformation
28
What are the symptoms of a HPV infection?
Presence of lesions, usually painless but may cause itching, bleeding or dyspareunia A relevant sexual history should be obtained to assess the risk of other STIs and sexual health needs
29
What are the signs of HPV infection?
Warts on moist non-hairy skin are usually soft and non-keratinised whereas those on dry, hairy skin are more likely to be firm and keratinised. Warts may be broad-based or pedunculated, pigmented or not. Warts are often found on areas subject to trauma on sexual intercourse.
30
What investigations would you perform for HPV infection?
Diagnosis by biopsy and viral typing is not routinely required. An appropriate screen for other STIs should be carried out.
31
What is the management for HPV infection?
Referral to a sexual health clinic 1/3 of warts regress spontaneously within 6 months Topical creams Cryocauterisation, diathermy, surgical removal or laser therapy
32
What is the immunology of HIV?
HIV binds to CD4 receptors on helper T lymphocytes, monocytes, macrophages and neural cells. CD4+ cells migrate to lymphoid tissue and the virus replicates to produce new virions. These are released and infect new CD4 cells. As infection progresses, depletion or impaired function of CD4+ cells leads to reduced immunity.
33
What are the 5 stages of HIV infection?
Acute infection Seroconversion Persistent generalised lymphadenopathy (only 30% of patients) AIDS-related complex (increased temp, night sweats, diarrhoea, weight loss +/- minor opportunistic infections) AIDS
34
How is HIV diagnosed?
Serum HIV-Ab by ELISA HIV RNA PCR Core p24 antigen in plasma
35
What is the treatment for HIV?
HAART - highly active anti-retroviral therapy 1 NNRTI + 2 NRTIs -or- PI + 2 NRTIs NNRTI - non-nucleoside reverse transcriptase inhibitor e.g. nevirapine, efavirenz NRTI - nucleoside reverse transcriptase inhibitor e.g. tenofovir, abacavir, zidovudine, didanosine PI - protease inhibitor e.g. indinavir, ritonavir, saquinavir
36
How is HIV monitored?
CD4+ T cell count (per microlitre) | HIV viral load (RNA copies/ml)
37
What are some AIDS-defining infections?
``` Candidiasis: oesophageal/lung Extrapulmonary cryptococcus Cryptosporidiosis for >1 month CMV: any organ except liver, spleen and lymph nodes Mycobacterium TB Toxoplasmosis of internal organs HSV with mucocutaneous ulcer >1 month Pneumocystis jiroveci pneumonia (PCP) Recurrent bacterial pneumonia ```
38
What are some AIDS-defining neoplasms?
Invasive cervical carcinoma Kaposi's sarcoma Primary CNS lymphoma Non-Hodgkin's lymphoma

41
What are the symptoms of chlamydia?
Female: vaginal discharge, dysuria, vague lower abdominal pain, fever, IMB or PCB, deep dyspareunia Male: unilateral testicular pain +/- swelling
42
What are the signs of chlamydia?
Female: friable inflamed cervix, mucopurulent endocervical discharge, abdominal tenderness, pelvic adnexal tenderness, cervical excitation Male: epididymal tenderness, mucoid or mucopurulent discharge Perineal fullness due to prostatitis
43
What investigations would you perform for chlamydia?
NAATs Vulvovaginal swab in females First catch urine sample in males
44
What is the management for chlamydia?
Antibiotics: Doxycycline 100mg BD for 7 days - contraindicated in pregnancy Single dose of 1g of azithromycin - can use in pregnancy and breastfeeding
45
What is the aetiology of trichomonas?
It is a flagellated protozoan. In adults, transmission is almost exclusively through sexual intercourse.
46
What are the symptoms of trichomonas?
Female: vaginal discharge - frothy, yellow, vulval itching, dysuria or offensive odour, lower abdominal pain Men: usually asymptomatic, dysuria, presence of urethral discharge
47
What are the signs of trichomonas?
Female: Local inflammation with vulvitis, vaginitis and cervicitis - strawberry cervix Male: no abnormal signs
48
What is the differential diagnosis for trichomonas?
