    Vaginal Yeast Infections Yeast Are Caused Byinfection an Overgrowth of Yeast in the Vagina

    •Vaginal Yeast infections Yeast are caused byInfection an overgrowth of yeast in the vagina. • Yeast infections can be treated with over-the-counter medications. • Many yeast infections can be treated without seeing a medical provider. Symptoms: • Vaginal Itching, burning, swelling • Vaginal discharge (thick white vaginal discharge that looks like cottage cheese and does not have a bad smell) • May have pain during sex • May be worse the week before your period Self-care measures: • Use an over-the-counter medication for vaginal yeast infections. These antifungal medications should contain butoconazole, clotrimazole, miconazole, or tioconazole and should be used for 3-7 days. Follow directions on medication insert. Note: Over-the-counter medications are available at the University Health Center Pharmacy (first floor of Student Success Center), local pharmacies, grocery stores and superstores (examples - Walmart or Target). • Change tampons, pads and panty liners often • Do wear underwear with a cotton crotch • Apply a cool compress to labia for comfort • Do not douche or use vaginal sprays • Do not wear tight underwear and do not wear underwear to sleep • Avoid hot tubs Limit spread to others: • It is possible to spread yeast infections to your partner(s) during vaginal, oral or anal sex. • If your partner is a male, the risk is low. Some men get an itchy rash on their penis. • If this happens have your partner see a medical provider. • If your partner is a female, you may spread the yeast infection to her. • She should be treated if she

    VOLUME - XVI ISSUE - XCIII MAY/JUN 2019 Vaginitis, also known as vulvovaginitis, is inflammation of the vagina and vulva. Symptoms may include itching, burning, pain, discharge, and a bad smell. Certain types of vaginitis may result in complications during pregnancy. 1 Editorial The three main causes are infections, specifically bacterial vaginosis, vaginal yeast Disease infection, and trichomoniasis. Other causes include allergies to substances such as 2 spermicides or soaps or as a result of low estrogen levels during breast-feeding or Diagnosis after menopause. More than one cause may exist at a time. The common causes 8 Interpretation vary by age. Diagnosis generally include examination, measuring the pH, and culturing the discharge. Other causes of symptoms such as inflammation of the cervix, pelvic Troubleshooting 13 inflammatory disease, cancer, foreign bodies, and skin conditions should be ruled out. 15 Bouquet Treatment depends on the underlying cause. Infections should be treated. Sitz baths may help with symptoms. Soaps and feminine hygiene products such as 16 Tulip News sprays should not be used. About a third of women have vaginitis at some point in time. Women of reproductive age are most often affected. The “DISEASE DIAGNOSIS” segment delves deep into the various CLINOCODIAGNOSTIC aspects of Vaginitis. “INTERPRETATION” portion highlights a very common disorder termed as BACTERIAL VAGINOSIS. Though not dangerous in itself, it predisposes to other sinister STDs. What we are discussing in “INTERPRETATION” is all about bacteria and the Primary investigation when t dealing with bacteria is GRAM's STAIN. Hence “TROUBLESHOOTING” part of this issue discusses GRAM's STAIN. What can possibly go wrong, how to identify and thereafter rectify the issues involved.

    GUIDELINES FOR THE MANAGEMENT OF SEXUALLY TRANSMITTED INFECTIONS 3. TREATMENT OF SPECIFIC INFECTIONS 3.1. GONOCOCCAL INFECTIONS A large proportion of gonococcal isolates worldwide are now resistant to penicillins, tetracyclines, and other older antimicrobial agents, which can therefore no longer be 32 recommended for the treatment of gonorrhoea. TREATMENT OF SPECIFIC INFECTIONS SPECIFIC OF TREATMENT It is important to monitor local in vitro susceptibility,as well as the clinical efficacy of recommended regimens. Note In general it is recommended that concurrent anti-chlamydia therapy be given to all patients with gonorrhoea, as described in the section on chlamydia infections, since dual infection is common.This does not apply to patients in whom a specific diagnosis of C. trachomatis has been excluded by a laboratory test. UNCOMPLICATED ANOGENITAL INFECTION Recommended regimens I ciprofloxacin, 500 mg orally,as a single dose OR I azithromycin, 2 g orally,as a single dose OR I ceftriaxone, 125 mg by intramuscular injection, as a single dose OR I cefixime, 400 mg orally,as a single dose OR I spectinomycin, 2 g by intramuscular injection, as a single dose. Note I Ciprofloxacin is contraindicated in pregnancy.The manufacturer does not recommend it for use in children and adolescents. GUIDELINES FOR THE MANAGEMENT OF SEXUALLY TRANSMITTED INFECTIONS I There is accumulating evidence that the cure rate of Azithromycin for gonococcal infections is best achieved by a 2-gram single dose regime.The 1-gram dose provides protracted sub-therapeutic levels which may precipitate the emergence of resistance. There are variations in the anti-gonococcal activity of individual quinolones, and it is important to use only the most active.

    Treatment of Recurrent Vulvo-Vaginal Candidiasis with Sustained-Release Butoconazole Pessary

    C ase R eport Singapore Med J 2012; 53(12) : e269 Treatment of recurrent vulvo-vaginal candidiasis with sustained-release butoconazole pessary Ling Zhi Heng1, MBBS, Yujia Chen1, MBBS, Thiam Chye Tan1,2, MBBS, MMed ABSTRACT Vulvo-vaginal candidiasis (VVC) is a common infection among women. 5% of women with acute infection experience recurrent vulvo-vaginal candidiasis (RVVC). There is currently no optimal or recommended regime for RVVC. Although antifungal agents, such as imidazoles, have been successfully used as a first-line treatment for acute VVC, its effectiveness is limited in RVVC. This could be due to patient factors, drug application (such as leakage) or dosing factors. A sustained-release (SR) bioadhesive vaginal cream (2% butoconazole nitrate) has incorporated VagiSite technology, a topical drug delivery system that allows SR of the drug. We describe its efficacy and the successful use of a butoconazole-SR formulation in the treatment of two cases of RVVC. Keywords: butoconazole, candidiasis, recurrent vulvo-vaginal Singapore Med J 2012; 53(12): e269–e271 INTRODUCTION Table I. Risk factors for recurrent vulvo-vaginal candidiasis. Candidiasis is a common cause of infective vaginal discharge Risk factors Examples experienced by women. 75% of women experience at least Microbial • Candida albicans species one episode of vaginitis during their lifetime. Recurrent vulvo- • Non-albicans Candida species vaginal candidiasis (RVVC) is defined as four or more episodes Host • Uncontrolled diabetes mellitus • Oestrogen excess – oral contraceptive pills, hormone of symptomatic vulvo-vaginal cadidiasis (VVC) in one year. Up replacement therapy, local oestrogen administration, to 5% of women of childbearing age have experienced RVVC.(1) pregnancy Common symptoms include vaginal discharge, vulvar pruritus, • Antibiotic-induced dyspareunia and dysuria.
