CONTEXT The diagnosis of papillary thyroid carcinoma (PTC) is based on nuclear features. These features may be present in focal areas in benign thyroid diseases and follicular adenoma (FA), leading to diagnostic difficulty. AIMS To evaluate the expression and pattern of the distribution of cytokeratin 19 (CK19) in PTC and compare its reactivity with other(More)
PROBLEM Recent reports indicate high incidence of genital infections, most of which are sexually transmitted. Although specific drugs and antibiotics are available for some, a safe spermicidal formulation with wide spectrum antimicrobial action would be a desirable addition to the presently available spermicides. METHODS Formulations at different(More)
Little is known about the molecular epidemiology of the human pathogenic fungus Cryptococcus neoformans in India, a country now in the midst of an epidemic of AIDS-related cryptococcosis. We studied 57 clinical isolates from several regions in India, of which 51 were C. neoformans var. grubii, 1 was C. neoformans var. neoformans, and 5 were C. neoformans(More)
BACKGROUND To determine the distribution of species of Candida and the risk factors associated with candidemia in Indian population for which we conducted a retrospective study for 5 years in a tertiary care centre of North India. MATERIALS AND METHODS Blood samples from 7,297 patients aged from 3 days to 85 years, suspected with candidemia, were(More)
OBJECTIVE Patients with diabetes mellitus are at increased risk of vulvovaginal candidiasis (VVC). Besides Candida albicans, they often have infection due to non-C. albicans Candida species such as C. glabrata. Oral single dose fluconazole (150 mg) is commonly used to treat VVC in non-diabetic individuals with response rate varying from 70 to 90%. However,(More)
A case of cerebral cladosporiosis caused by Cladosporium trichoides (bantianum) now known as Xylohypha bantiana is described and illustrated. Predisposing debilitating diseases were not detectable. The Cladosporiosis diagnosis was based on visualisation of hyphal element in direct Gram's stain, direct KOH preparate of pus from brain abscess and on repeated(More)
OBJECTIVES In cryptococcosis, fluconazole is a standard prophylactic, therapeutic and maintenance option, particularly in the expanding HIV/AIDS group. However, its excessive use may lead to resistance in Cryptococcus neoformans. Variations in clinical response to fluconazole have already been noted elsewhere, and cases of post-therapy relapse are not(More)
Infections are the major cause of morbidity and mortality in acute leukemia patients. Case records of 91 consecutive patients (AML-48, ALL-40, RAEB-t/AML-3) treated between January 1997 and July 1999 were studied to determine the type, frequency and severity of infections. Patients' median age was 36 y (range 6-66) and male to female ratio was 2.5:1. A(More)
Fungal agents causing onychomycosis in an Indian population were studied in a hospital based study. It revealed that onychomycosis is more common in adult males, and that finger nails were more often affected compared with toe nails. Occupation did not seem to be related to infection. Trichophyton rubrum was the commonest fungus isolated (49.3%) followed by(More)
The prevalence of specific serotypes of Cryptococcus neoformans in a given area bears on regional epidemiological patterns, the expected spectrum of clinical disease, and predicted response to therapy. In this retrospective study we analyzed the serotypes of 45 degrees C neoformans isolates from 36 North Indian patients with varied clinical presentations.(More)
