Vaginal Discharge

Discharge

Frothy, foul smelling copious discharge

Trichomonas Vaginalis
• Almost exclusively STI • May be asymptomatic • Presents with offensive vaginal discharge and vulval itching in women and uretheritis in men. • Sexual partners should be notified and treated. Advise against sexual intercourse until both treated.

Trichomonas Vaginalis
 Recommended regimen for vaginal infection:
–Metronidazole,2g orally, in a single dose or –Note: reported cure rate in women : 82-88% but may be increased to 95% if partners are treated simultaneously.  Alternative regimen: -metronidazole, 400mg or 500mg orally, twice daily for 7 days

Thick flowing discharge

Bacterial Vaginosis
• Clinical syndrome resulting from replacement of normal hydrogen peroxide-producing Lactobacillus sp. In the vagina by high concentrations of anaerobic bacteria, such as Gardnerella vaginalis & Mycoplasma hominis. • Cause of microbial alteration is not fully understood. • Endogenous reproductive tract infection/treatment of sexual partners has not been of demonstrated benefit.

Bacterial Vaginosis & surgical procedures
• Women with BV scheduled to undergo reproductive tract surgery or a therapeutic abortion should receive treatment with metronidazole. • Recommended regimen:

Treatment Options for Genital Herpes – recommended regimen
• For first clinical episode:
– Acyclovir , 200mg orally, 5 times daily for 7 days or – Acyclovir, 400mg orally 3 times daily for 7 days – The topical application does not do much

Genital Herpes Infection - recurrent infections

– Acyclovir, 200mg orally, 5 times daily for 5 days or – Acyclovir, 400mg orally, 3 times a day for 5 days or – Acyclovir, 800mg orally, twice daily for 5 days

Herpes in Pregnancy
• During the first clinical episode of genital herpes, treat with oral acyclovir • Vaginal delivery in woman who develop primary genital herpes shortly before delivery puts babies at risk for neonatal herpes. Careful history and exam serve as guide to need for caesarean section in mothers with genital herpes lesions • Recommended regimen for neonates: – Acyclovir, 10mg/kg I.V., 3 times a day for 10-21 days

Herpes and HIV Co-infection
• Deficient immunity-persistent &/or sever mucocutaneous ulcerations may occur, often involving large areas of perianal, scrotal or penile skin. Lesions-painful & atypical. • Natural History of herpes may be altered • Respond to acyclovir but dose may have to be increased and treatment given for longer than standard recommended period. • Patients may benefit from chronic suppresive therapy

Herpes and HIV Co-infection
• Recommended regimen for severe disease: acyclovir, 5-10 mg/kg IV, every 8 hours for 5-7 days until clinical resolution is attained • Recommended regimen for severe herpes lesions with co-infection with HIV
– Acyclovir, 400mg orally, 3-5 times daily until clinical resolution is attained

Suppressive Therapy
• Reduces the frequency of genital herpes recurrences by more than 75% among patients who have frequent recurrences(6 or more recurrences per year). Safety demonstrated for daily acyclovir therapy for 6 years • Suppressive therapy with acyclovir reduces, but does not eliminate asymptomatic viral shedding.

Suppressive Therapy
• Recommended regimen for suppressive therapy:
– Acyclovir, 400mg orally, twice daily continuously

Genital Warts – recommended regimen- chemical
• Self applied by patient:
– Podophyllin 0.5% solution or gel, twice daily for 3 days, followed by 4 days of no treatment, cycle repeated up to 4 times (total volume of podophyllin should not exceed 0.5 ml per day) or – Imiquimod 5 % cream [NOT available in FIJI] applied with a finger at bedtime, left overnight, 3 times a week as long as 16 weeks. The treatment area should be washed with soap and water 6-10 hours after application. Hands washed with soap & water immediately after application – * safety of both not established in pregnancy

Genital Warts – recommended regimen- chemical
• Provider administered:
– Podophyllin 10-25% in compound tincture benzoin, applied carefully to warts, avoiding normal tissue. External genital and perianal warts must be washed thoroughly after 1-4 hours after application of podophyllin. Should be allowed to dry before speculum removed. Repeated at weekly interval. – Use of podophyllin in pregnancy & lactation is contraindicated or – Trichloroacetic acid(TCA), applied carefully to warts followed by powdering of treated area with talc or sodium bicarbonate to remove acid. Repeat weekly.

Genital Warts - Physical

• Recommended regimen:
– Lindane 1% lotion or cream-rubbed gently but thoroughly into infested area and adjacent hairy areas & washed off after 8 hours. or – Pyrethrins– applied to infested area and adjacent hairy areas& washed off after 10 minutes; retreatment indicated after 7 days if lice are found or eggs are observed at hair-skin junction. – Clothing & bed linen that may have been contaminated by patient in two days prior to start of treatment should be washed and dried well , or dry cleaned

What is it?

Scabies

Scabies

Scabies causing eczema-like hand condition

Treatment of Scabies in Adults, Adolescents and older children
• Lindane 1% lotion or cream- apply thinly to all areas of the body from neck down and washed off thoroughly after 8 hours or • Permethrin cream 5 % or • Benzyl benzoate 255 lotion, applied to entire body from neck down,nightly for two nights; patients may bath before reapplying the drug and should bathe 24 hours after the final application or NB : Lindane is not recommended for pregnant and lactating women Resistance to lindane has been reported in some areas.

Treatment of Scabies:
in infants, children <10 years, pregnant and lactating women

• Recommended regimen:
– Permethrin 5% cream, applied in the same way as sulphur regimen described above

Uretheral Discharge SYNDROME

Uretheral Discharge
• Pathogens
– Neisseria Gonorrhoea (gonococci) – Chlamydia trachomatis (chlamydia)

• Syndromic treatment
– therapy for uncomplicated gonorrhoea plus – Therapy for chlamydia

Persistent or Recurrent Uretheral Discharge
• May result from :
– Poor compliance to treatment – Drug resistance – Re-infection – Other co-infection – (Trichomonas Vaginalis)

Vaginal Discharge SYNDROME

Vaginal Discharge
• Symptom of abnormal vaginal discharge is highly indicative of vaginal infection but poorly predictive of cervical infection • All women presenting with vaginal discharge should receive treatment for trichomonas and Bacterial Vaginosis • Among women presenting with vaginal discharge, one can attempt to identify those with increased likelihood of being infected with Neisseria gonorrhoea &/or Chlamydia trachomatis

Vaginal Discharge
• Assessment of woman’s risk status may be useful to determine cervicitis – (gram stain in referral clinic – GC & T. vaginalis) – Local prevalence of GC & CT in women presenting with vaginal discharge is important when making the decision to treat for cervical infection. Higher the prevalence the stronger the justification for treatment – Woman with vaginal discharge and positive risk assessment should therefore be offered treatment for gonococcal and Chlamydial infection

Vaginal Discharge Summary
• Vaginal Discharge VAGINITIS • Trichomonas • Bacterial vaginosis • Candidiasis • Cervical Discharge CERVICITIS • Gonococcal • Chlamydial

Lower Abdominal Pain SYNDROME

Lower Abdominal Pain (LAP)
• All sexually active women presenting with LAP should be carefully evaluated for the presence of salpingitis &/or endometritis – elements of pelvic inflammatory disease (PID) • All women with presumptive STI should have routine bimanual & abdominal examination since some women with PID will be asymptomatic • Endometritis- vaginal discharge +/-bleeding &/or uterine tenderness on pelvic examination • PID – abdominal pain, dyspareunia,vaginal discharge, menometorrhagia, dysuria, fever, and sometimes nausea and vomiting

Pelvic inflammatory Disease (PID) • PID is inflammation and infection of the upper genital tract in women, typically involving fallopian tubes, ovaries, and surrounding structures • Difficult to diagnose because of varied clinical manifestations

PID
• PID becomes highly probable when one or more of symptoms described earlier are seen in woman with adnexal tenderness, evidence of lower genital tract infection and cervical motion tenderness. Enlargement or induration of one or both fallopian tubes , a tender pelvic mass, and direct or rebound tenderness may also be present. Patients temperature may be elevated but is normal in many cases. • Clinicians should err on overdiagnosing and treating suspected cases

PID – etiological agents
• Neisseria Gonorrhoea • Chlamydia trachomatis • Anaerobes ( bacteroides spp., gram positive cocci) • Facultative gram negative rods • Mycoplasma hominis * Impossible to differentiate clinically & precise microbiological diagnosis is difficult, the treatment regimen must be effective against this broad range of pathogens

Pelvic Inflammatory disease (PID) hospitalisation considered:
• Diagnosis uncertain • Surgical emergencies (appendicitis, ectopic pregnancy) cannot be excluded; • A pelvic abscess suspected • Severe illness precludes management on an outpatient basis • The patient is pregnant • Patient is unable to follow or tolerate the outpatient regimen or • The patient failed to respond to outpatient therapy

Outpatient Therapy - LAP
• Recommended regimen: – Single dose therapy for uncomplicated gonorrhoeaceftriaxone (other single dose regimen have not been formally evaluated) plus – Doxycycline 100mg twice daily or tetracycline 500mg orally, 4 times daily for 14 days plus – Metronidazole, 400-500mg, twice daily for 14 days
NB. Patients taking metronidazole should be cautioned from taking alcohol Tetracyclines are contraindicated in pregnancy

Outpatient Therapy - LAP
• Adjuncts to therapy : removal of intrauterine device (IUD)
– If PID should occur with an IUD in place, treat the PID using appropriate antibiotics – There is no evidence that removal of the IUD provides any additional benefit – Thus, if the individual should wish to continue its use ,it need not be removed. – If she does not want to keep the IUD, removal is recommended after antimicrobial therapy has been commenced. – When IUD is removed contraceptive counselling is necessary Follow-up : Outpatients with PID should be followed up after 72 hours and admitted if their condition has not improved

Acquired Immune Deficiency Syndrome

What happened on Sept 11 in 2001?…

Consider this, which also happened on that day:
• 16000 people were diagnosed with HIV • 8600 people died of AIDS

How many pictures and front covers of magazines did you see that were devoted to the 9/11 tragedy?
How many have you seen that were dedicated to the people who make up the statistics you just saw?

The SARS virus claimed 500 lives in six months; HIV/AIDS kills 8600 people every single day.

IMMUNOLOGY

What does HIV do inside the body?

Normal response during infections

Infection by HIV

When HIV destroys most of the defenses…

CD4 and HIV Viral Load

Signs of HIV Infection

Ervin “Magic” Johnson - 1991

Greg Louganis - 1995

Tommy Morrison - 1996

Asymptomatic HIV
• No sign or symptoms for many years

Symptomatic Phase
• After 7-10 years later when ample damage is done to the CD4 cells, simple opportunistic infection begin to happen on and off for couple of months

First signs of HIV disease Fever

First signs of HIV Disease Headaches-forgetfulness

First signs of HIV disease Painless Lymph node swelling

Tinea infections

Gingivitis

Seborrhic Dermatitis

Molluscum Contagiosum

Herpes Zoster

Pulmonary TB

Sinusitis

Signs of Advanced HIV disease Weight loss > 10%

Other Symptomatic HIV Complexes (ARC)
• Unexplained diarrhea >1/12 • Night sweats • HIV Dementia

When the majority of the immune cells are destroyed, many other infections and cancer begin to invade the body and cause illness

AIDS Defining Illnesses
• Opportunistic Infections:
– – – – – – – – – – – – – – Cryptococcosis Toxoplasmosis HIV encaphalopathy Cytomegalovirus disease Esophageal Candidiasis PCP Extrapulmonary TB Invasive Cervical Cancer Herpes simplex ulcerations > 1/12 Kaposi sarcoma Lymphoma Non-typhoid salmonella septicemia Cryptosporidiosis diarrhea >1/12 MAC

Without proper management… AIDS is almost always… FATAL!

HIV TREATMENT
Dr. Arvin C. Chaudhary
MBBS (Fiji), MSc in STI/HIV Medicine (London)

Coordinator for Sexual Health, STI & HIV Medicine Western Health Service

Management
• TREAT HIV
– Anti-retroviral – Palliative – Multi-discipline approach

• TREAT OI
– According to guidelines

Anti-Retro Viral Therapy ARV
• HIV infected person may have millions of HIV particles in every ml of their blood. • The aim of treatment is to reduce the viral load to below 50 copies/ml (undetectable)

ARV- Mode of Action

CD4 and Viral load with ARV

Palliative Care
• Pain Management with effective analgesic • Provide emotional support- counseling • Provide spiritual support • Counsel family and corers • Prevent dehydration • Meet nutritional support

Answer is to:
• • • • • … don’t get it at the first place (ABCD) … Know your P.E.P … get tested to detect it in early stages … commence management early … stick to management

Thank You
