Natural history of glaucoma.

Purpose: To present an overview of the recent observations and research that shed light on the understanding of open and closed angle glaucoma. Methods: Literature review. Results: Glaucoma is a major eye problem afflicting millions of people worldwide. As the population increases, the number of people with glaucoma also increases, with glaucoma becoming an increasing public health concern. This paper presents the natural history of open angle and angle closure glaucoma. We examine the glaucomatous progression in terms of changes in optic disk morphology and visual fi elds as well as the risk factors for progression. Conclusions: This present review highlights the magnitude of glaucoma globally and the need for a greater understanding of this disease and its natural progression.

Prevalence, species distribution and antifungal sensitivity of vaginal yeasts in infertile women.

A total of 326 high vaginal swabs from infertile women attending the Institute of Reproductive Medicine were cultured from June 1999 to May 2000. Candida species was isolated from 42(12.88%) patients. Candida albicans (40.47%) followed by Candida glabrata (38.09%) were the most common isolates. Other species included Candida tropicalis (14.28%) and Candida krusei (7.14%). All isolates were tested for sensitivity by disc diffusion method on Yeast Nitrogen Agar base towards four antifungals. Seven (16.7%) candida strains showed resistance to Fluconazole and 19(45.23%) of the strains showed resistance to Itraconazole, and 4(9.5%) strains showed resistance to Nystatin. There was no resistance to Amphotericin B. Of the 7 strains resistant to Fluconazole, 3 were Candida krusei, 3 were Candida glabrata and 1 was Candida tropicalis.

Vaginal carriage of group B Streptococcus in infertile women.

From May, 1999 to April, 2000, 256 high vaginal swabs were culture from asymptomatic infertile women attending the out-patient department of the Institute of Reproductive Medicine. 41 strains of Streptococcus agalactiae were isolated from 33 patients (12.89%). Five patients had repeated isolations even after adequate therapy.

Studies on the comparative efficacy of mebendazole, flubendazole and niclosamide against human tapeworm infections.

The efficacy of Mebendazole and Niclosamide was studied in two groups of 24 and 38 cases, respectively of patients suffering from taeniasis. Mebendazole with dose schedule of 200 and 300 mg twice daily for 3 consecutive days showed a cure rate of 71.42% and 92.30%, whereas Niclosamide at the dose rate of 200mg per patient was 94.76% effective. Flubendazole showed a cure rate of 66.66% only. Mebendazole and Niclosamide possess high taeniacidal activity, ability to reduce the clinical symptoms of taeniasis without any side effects. Niclosamide with high activity and excellent tolerance, is a drug of choice for the treatment of taeniasis in single dose treatment while for hymenolepsiasis it needs extended course.
