Localized cutaneous leishmaniasis (LCL) in India is due mostly to Leishmania tropica. It is mainly endemic in the deserts of Rajasthan. Recently, Himachal Pradesh has been identified as a new endemic focus for the disease. In the last few years, the number of new cases has been increasing almost to epidemic proportions. This report presents the preliminary findings of clinico-epidemiologic and investigative results of 161 new localized cases of LCL seen between May 2001 and December 2003. The study populaton was composed of 80 males and 81 females between 10 months and 75 years of age. All were indigenous to the sub-alpine valley along the Satluj River in the mountainous region of the Kinnaur District (altitude = 700-2,900 meters). Most patients were seen from April to September and had 1-8 lesions (duration = 1-6 months) that involved mainly the face. Tissue smears were positive for amastigotes in 37% and histopathology showed non-caseating epitheloid cell granuloma in 77% of the cases. Analysis by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) of the ribosomal gene region of 10 biopsy specimens showed amplicons indistinguishable from L. donovani in eight cases and L. tropica in two cases. Leishmania was cultured on modified Nicole-Novy-McNeal (NNN) medium containing RPMI 1640 medium and heat-inactivated fetal bovine serum from 13 of 38 biopsy samples. Three of these isolated strains were identified as L. donovani while a fourth was L. tropica by PCR-RFLP of the ribosomal internal transcribed spacer region. One strain had a gp63 sequence identical to that of east African strains. Another strain had a unique gp63 sequence that has not been found in L. donovani complex strains. Sand flies trapped in the cattle sheds of a few patients were identified as Phlebotomus longiductus (Parrot 1928). Treatment with intralesional sodium stibogluconate was effective in all patients without any major side effects. One patient developed lupoid leishmaniasis that responded to higher dose of sodium stibogluconate. Though rarely reported as a cause of LCL, L. donovani seems to be the predominant pathogen in this new focus of cutaneous leishmaniasis. Phlebotomus longiductus is a possible vector, albeit based on circumstantial evidence.

Objectives A prospective study was conducted in the Department of microbiology (IGMC) and the Department of obstetrics & gynecology (KNH), Shimla, and Himachal Pradesh over a period of 1 year from May 2005 to April 2006 on 463 asymptomatic pregnant females with a period of gestation (POG) 28 weeks or less. The aim was to find out the prevalence of pregnancy associated bacteriuria and bacterial causes responsible for this entity. Methods The pregnant women were taught to collect the urine sample by aseptic technique which was then subjected to semi quantitative culture method. Results Significant bacteriuria was present in 7.34% cases. About 78% samples were found to be sterile.Insignificant count and growth of contaminants was positive in 1 and 13% samples, respectively. The most common etiological agent came out to be E. coli followed by other gram positive and gram negative organisms. Conclusion Asymptomatic bacteriuria is a common occurrence which should be diagnosed and treated in early pregnancy keeping in view its adverse effects on pregnancy.

Our study highlights the recent emergence of Gram-positive organisms as predominant cause of neonatal septicemia in this part of Sub-Himalayan region, along with the review of literature which shows similar results from North India and rest of the world too. Though Gram-negative bacteria still remain the main cause of mortality in neonatal septicemia, we want to dispel the common notion among practitioners that they are the predominant isolates in neonatal septicemia.
