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.

Ophthalmomyiasis is an infestation of eye with larvae or maggots of certain flies. Oestrus ovis (sheep nasal botfly) belonging to family Oestridae is the most common cause of human myiasis. We describe here an acute presentation of a case of external ophthalmomyiasis, i.e., infestation of conjunctiva due to first instar larvae of Oestrus ovis. In this case report the occurrence, diagnosis and treatment all took place in the setting of a single day. Prompt treatment by removal of larvae mechanically followed by instillation of antibiotic and steroid eye drops helped to prevent serious complications. The taxonomic identification of fly is also important as some fly species are capable of penetrating deeper tissues of eyes, which is sight threatening.

Background/Aim:We aimed to study whether sedation reduces discomfort during endoscopy and a comparison of longer-acting diazepam with shorter-acting midazolam.Patients and Methods:A prospective, randomized, single-blinded study was conducted at the Department of Medicine at Government Medical College and Hospital, Chandigarh, and was completed over a period of 6 months. The patients were randomized to receive either placebo or sedation with midazolam or diazepam before endoscopy. The endoscopist and the observer recording patient’s/physician’s responses were blinded to the drugs administered. Two hundred and fifty two consecutive patients undergoing diagnostic or therapeutic upper gastrointestinal endoscopy were recruited. The patient’s discomfort and the physician’s comfort during the procedure were recorded on a visual analogue scale rated from 1-10 with-in 10 minutes of the procedure by an independent observer. The Patient’s discomfort ratings were further divided into 3 groups, comfortable (score, 1-3), satisfactory (score, 4-7) and uncomfortable (a score of >7). Similarly the physician’s ease of performing the procedure was also recorded on the same scale. This was again divided into 3 groups: easy (score, 1-3), satisfactory (score, 4-7) and difficult (a score of >7).Results:Out of the total of 252 patients, 82 patients received no sedation (group I), 85 received diazepam (group II) and 85 received midazolam (group III). There was no statistical difference in the discomfort experienced by the patients during endoscopy when sedation was used (P=0.0754). Out of 252 patients, 49 underwent endoscopic procedures. Nineteen patients were included in group I, 18 in group II and 12 in group III. Only 10 (20%) patients undergoing endoscopic procedures complained of significant discomfort, but there was no difference in the ones undergoing interventions with or without sedation (P=0.854). The physicians were more comfortable in performing endoscopic procedure in sedated patients, however, the difference between patients in group II and group III was not statistically significant (P=0.0461). Both diazepam and midazolam fared equally well in increasing physician’s comfort (P=0.617).Conclusion:There was no difference in the patient’s discomfort with regard to the sedative used (midazolam or diazepam). Although endoscopy was easy or satisfactory in the majority of patients in the unsedated as well as the sedated groups, more often the endoscopist found it difficult to do endoscopy on the unsedated patients.

Primary amoebic meningoencephalitis is a rare fatal meningitis caused by free living amoeba Naegleria fowleri, found in freshwater ponds and lakes. It infects children and young adults with exposure due to swimming or diving. We report a case of N. fowleri meningitis in a 6-year-old boy who presented with signs and symptoms of acute bacterial meningitis. No history of travelling or swimming was present. However, the boy frequently played with water stored from a "kuhl" (diversion channels of water). Wet mount of cerebrospinal fluid (CSF) revealed amoeboid and actively motile flagellate forms of trophozoites. CSF culture done on 1.5% non-nutrient agar plates with a lawn culture of Escherichia coli kept at 37°C for 15 days did not reveal any growth. The test of flagellation on passing CSF in distilled water was however positive in 3 h. Water of the "kuhl" from the stored tank also showed actively motile trophozoites similar to the forms obtained from the CSF. Based on our reports, the boy was immediately treated with amphotericin B, rifampicin and fluconazole for 21 days. Repeat CSF examination after 14 days did not reveal any trophozoites in wet mount and patient was discharged after 3 weeks of successful treatment.

Background: The present study was done to assess the bacteriological quality of drinking water in and around Shimla in the event of an outbreak of hepatitis E in Shimla city, January 2016. Methods: Total 1098 water samples from different sources were received from January to July 2016. The bacteriological analysis of water was done by the multiple tube technique. Results were interpreted after 48 hours of incubation of the water sample in MacConkey bile broth medium in accordance with Mc Crady probability table. Results: A total of 1098 water samples were received in the Microbiology laboratory of which 129 (11.74%) were unsatisfactory, 25 (2.27%) satisfactory and rest 925 (84.24%) were excellent. Nearly 9.21% samples from water tanks, 2.3% from public taps were unsatisfactory but water samples from all the water ATM s were excellent. Escherichia coli were the commonest isolate 35.6%, Klebsiella pneumoniae 31.6%, Klebsiella oxytoca 19.3%, Enterobacter sps 8% and Citrobacter sps 2%. In the corresponding period 477 patients had come to the health facilities for clinical symptoms of jaundice. The serum samples from clinically suspected cases were subject to antibody testing for IgM HAV and IgM HEV and it revealed that 109 (23%) were positive for HAV while 253 (53%) were positive for HEV. During the above period 75 (15%) patients had co-infection with both HAV and HEV. Conclusions: Bacteriological assessment of drinking water is essential and should be carried out on regular basis so as to prevent outbreaks of Hepatitis A and E and other water borne diseases.
