Kojic Acid vis-a-vis its Combinations with Hydroquinone and Betamethasone Valerate in Melasma: A Randomized, Single Blind, Comparative Study of Efficacy and Safety.

Background: Melasma is a relatively common, acquired symmetric hypermelanosis characterized by irregular light to gray-brown macules involving sun-exposed areas. Kojic acid, with its depigmenting potential due to tyrosinase inhibition and suppression of melanogenesis, has become a vital component of the dermatologists' armamentarium against melasma.

Aim: To study and compare the efficacy of kojic acid 1% alone, vis-a-vis its separate combinations with 2% hydroquinone or 0.

Disseminated cryptococcosis and fluconazole resistant oral candidiasis in a patient with acquired immunodeficiency syndrome (AIDS).

Disseminated cryptococcosis and recurrent oral candidiasis was presented in a-heterosexual AIDS patient. Candida tropicalis (C.tropicalis) was isolated from the oral pseudomembranous plaques and Cryptococcus neoformans (C.

A clinical and mycological study of onychomycosis in HIV infection.

Background: Onychomycosis is one of the early manifestations of HIV infection with a prevalence of 15-40%. Multiple nail involvement, isolation of both common and rare species and resistance to treatment are the characteristics of onychomycosis in HIV.

Aim: To study the epidemiology, clinical manifestations of onychomycosis in HIV-infected individuals and to identify the various causative fungi microbiologically.

A comparative clinical study of sisomicin cream versus mupirocin ointment in pyodermas.

This study was designed to compare the efficacy and safety of sisomicin cream (0.1%) or mupirocin ointment (2%) in the treatment of primary or secondary pyodermas requiring topical antibiotic therapy alone. In the evaluable patients (n=290), impetigo was the commonest clinical condition reported.

Multicenter, open-label, non-comparative study of a combination of polytar and zinc pyrithione shampoo in the management of dandruff.

Background: Dandruff is a common condition in clinical practice. We undertook a study to evaluate the efficacy and safety of a combination of zinc pyrithione and polytar in a shampoo base for the treatment of dandruff.

Methods: A combination of polytar (1%) and zinc pyrithione (1%) was used for 4 weeks to treat 954 patients suffering from mild to severe dandruff.
