Seminar VIObstetric & Gynecology Prepared & Presented by: Ibrahim Tawhari.
SCENARIO I: • A16-year-old female who presents to her private gynecologist’s office. • She is complaining of abdominal pain, perineal itching, and vaginal discharge for 7 days. • Lab. Tests: • DNA probe results: +ve for both: Gonorrha & Chlamydia.
SEXUALLY TRANSMITTED INFECTIONS (STIs) & VAGINAL DISCHARGE Prepared & presented by: Ibrahim Tawhari.
SEXUALLY TRANSMITTED INFECTIONS (STIs) Prepared & presented by: Ibrahim Tawhari.
SEXUALLY TRANSMITTED INFECTIONS: • They are infections whose primary route of transmission is SEXUAL CONTACT. • Sexually transmitted infections (STIs) are one of the most well-recognized health problems worldwide. • However, they are difficult to track: • Asymptomatics. • Non-exposed areas.
SEXUALLY TRANSMITTED INFECTIONS: • Most of the published data on the prevalence and incidence of STIs come from developed countries. • Information about STIs in Islamic, where non-marital sex and homosexuality are forbidden by religion countries are limited. • An assumed low prevalence of STIs and religious and cultural intolerability of non-marital sex and homosexuality in Islamic countries are expected reasons for the limited data.
SEXUALLY TRANSMITTED INFECTIONS: • Islamic rules and values are essential and should be of highest priority for policymakers because of the potential of such infections to spread particularly among the youth.
SEXUALLY TRANSMITTED INFECTIONS: • Risk Factors: • Hx of previous STI. • Contact with infected person. • Sexually active individual 25 years. • Multiple sexual partners. • Un-protected sexual intercourse. (No barrier). • Drug abuse,..
CAUSES: • HSV. • HPV. • HBV. • HIV. • Chancroid. • Syphilis. • LGV. • Granulomainguinale. • Chlamydia. • Gonorrhea. • Candida albicans • Chlamydia trichomatis.

CLASSIFICATION: STIs STIs with Genital Ulcers STIs without Genital Ulcers Painful Painless • Syphilis. • LGV. • Graulomainguinale • HSV. • Chancroid.
CLASSIFICATION: STIs STIs with Genital Ulcers STIs without Genital Ulcers STIs with PAINFUL Genital Ulcers Painful Painless • HSV. • Chancroid. • HSV. • Chancroid.
HSV: • A DNA virus. • The most common cause of genital ulcer disease. • Contagious. • Transmission: • Direct mucus membrane contact.
HSV: • Types: HSV I, HSVII. • HSVI usually causes lesions abovethe level of umbilicus. • HSVII usually causes lesions belowthe level of umbilicus. HSV I HSV II
HSV: • Symptoms: • Primary: • Systemic: viremia. • Painful skin lesions. Latency Retrograde Transport Stress Reactivation: Anterograde Transport • Recurrent: • Localized. • No systemic manifestations.
HSV: • Clinical Examinations: • Primary lesions: • Systemic: fever, flu like,… • Clear vesicles at site of exposure. • Spontaneously rupture shallow painful inflamed ulcer. • Recurrent lesions: • Localized, milder.
HSV: • Diagnosis: • Lab tests: • Viral isolation is the most accurate. • Serology: ELISA for specific antibodies. • Cytology: • Multinucleated Gaint Cells.
HSV: • Management: • Acyclovir (200 mg PO q24 hrs for 5 days). • Valacyclovir: risk of sexual transmission by 50%. • Famciclovir.
CHANCROID: • Caused by: Hemophilusducreyi. • Facilitates transmission of HIV. Pathophysiology: Painful Ulcer Contact Pastule Ulcerate Develop within 72 hours
CHANCROID: • Clinical Examinations: • Characterisically “Ragged Edge Ulcer”. • Shallow and non-indurated. • Seen on vulva, vagina or cervix. • Tender inguinal lymphadenopathy may develop.
CHANCROID: • Ragged Edge Ulcer
CHANCROID: • Lab Tests: • +ve culture is confirmatory. • However, this organism is slowly growing… Gram stain is not reliable. • Diagnosis is made after ruling out syphilis. • Management: • Azithromycin. • Ceftriaxone.

CLASSIFICATION: STIs STIs with Genital Ulcers STIs without Genital Ulcers STIs with PAINLESS Genital Ulcers • Syphilis. • LGV. • GranulomaInguinale Painful Painless • Syphilis. • LGV. • Graulomainguinale
SYPHILIS: • Caused by: Treponemapallidum. • A motile anerobic spirochete.
SYPHILIS: Primary Syphilis (Localized Chancre; painless) Secondary Syphilis • Spirochetemia • CondylomaLata; painless 2/3 1/3 No clinical findings Gumma (CNS, CVS, bone,..) Latent Syphilis Tertiary Syphilis
SYPHILIS: • Maternal Syphilis: • Primary Syphilis: Chancre: “Rolled Edge Ulcer” • Usually, disappears spontaneously.
SYPHILIS: • Secondary Syphilis: CondylomaLata: • Maculopapular rash. (money spots). • Usually, disappears spontaneously without treatment.
SYPHILIS: • Tertiary syphilis: Gumma
SYPHILIS: • Diagnosis: • Non specific tests: • VDRL: • If positive, confirmatory tests are requested. • False +ve with some autoimmune diseases; SLE, APL, … • Rapid plasma regain test (RPR test). • Dark field Microscopy: • For exudate lesion of chancre in primary syphilis and condylomalata in secondary syphilis.
SYPHILIS: • Diagnosis: • Confirmatory tests: • Fluorescent Titer Antibody-Absorption (FTA-ABS). • Microhemagglutination assay for antibodies to T. Pallidum (MHA-TP).
SYPHILIS: • Management: • Penicillin G is the drug of choice. • 2.4 million units of Benzathin Penicillin G are given IM.
SYPHILIS: • Non pregnant: Tetracycline. • Pregnant: Penicillin + Desensitization • If a woman is allergic to penicillin??????!!!!!
LGV: • Caused by: L serotype of Chlamydia trichomatis. • Clinical Features: • INITIAL lesion is a PAINLESS ulcer that heals spontaneously. • Few weeks later, • Peri-rectal or inguinal painful lymphadenopathy may develop. • Classic clinical sign is: “GROOVE SIGN” or Double Genitocrural Folds. = A depression between two inflamed groups of lymph nodes
LGV: GROOVE SIGN
LGV: • Lab. Tests: • Culture of aspirated fluid from tender lymph nodes. • Management: • Doxycycline, or • Erythromycine. • Fluctuant nodes SHOULD be ASPIRATED to prevent sinus formation.
GRANULOMA INGUINALE : • Caused by: Klebsiellagranulomatis. • Not very common: • Not highly contagious. • Chronic exposure is needed. Chalymmmatobacteriumgranulomatis
GRANULOMA INGUINALE: • Clinical Features: • Initially: Painless vulvar nodules. • Later the nodules burst, creating open, fleshy, oozing lesions--- “BEEFY RED ULCER”
GRANULOMA INGUINALE: BEEFY RED ULCER
GRANULOMA INGUINALE : • Lab. Tests: • Microscopic examination of ulcer smear: “DONOVANBODIES” --- This is why it is also called: “ DONOVANOSIS”.
GRANULOMA INGUINALE : • Management: • Doxycycline. • Co-trimoxazole.
