ABSTRACT
Blood stream infections related to central venous catheterization are one of the major device-associated infections reported. Patients admitted in critical care units requiring central venous catheterization and presenting with signs of septicemia during catheterization period were investigated for catheter-related blood stream infections (CRBSI). The CRBSI rate was 9.26 per 1000 catheter days in general with highest rate in neonatal intensive care unit (27.02/1000 days). Site of insertion of catheter and duration of catheterization did not show the influence on the CRBSI rate. Coagulase-negative Staphylococci were the predominant cause. Mortality of 33% was observed in patients with CRBSI. Since central venous catheters are increasingly being used in the critical care, regular surveillance for infection associated them are essential.

A mycological study of onychomycosis was undertaken in 88 patients. The nails were judged to be infected by their clinical appearance. Direct microscopy of the nail clips in 20% KOH solution was positive in 72 (81.8%) and culture was positive in 43 (48.8%) cases. Out of the samples cultured, dermatophytes were grown in 26 cases (29.5%), non dermatophyte moulds in 12 (13.6%) and Candida spp. in 5 (5.6%) while 45 (51.1%) samples yielded no growth. Amongst dermatophytes, T. rubrum was found to be commonest etiological agent (57.6%) followed by T. mentagrophyte. Amongst the non-dermatophyte mould (NDM), Aspergillus spp. was the most prevalent species followed by Alternaria spp, Curvularia spp. and Fusarium spp. Commonest age group affected was above 31 years. Males were predominantly affected (65%), male to female ratio being 1.8:1. Fingernails were affected more frequently than toe nails with the ratio of 3:1. Distal and lateral subungual onychomycosis (DLSO) was more common (50%) than other clinical pattern followed by proximal subungual onychomycosis (PSO) (20.4%), white superficial onychomycosis (SWO) (2%), total dystrophic onychomysosis (TDO) (14%) and paronychia (10.2%).
