Mycological Pattern of Dermatophytosis in and Around Shimla Hills

Introduction: Dermatophytosis is defined as the fungal infection of the skin, hair and nails by a group of keratinophillic fungi known as dermatophytes. Aims and Objectives: This study is an attempt to find out various species of dermatophytes in clinically suspected cases of dermatophytosis. Materials and Methods: One hundred samples were subjected to direct microscopy by potassium hydroxide wet mount (KOH) and isolation on culture with Sabourauds dextrose agar. Results: Out of these 80 (80%) samples were KOH positive while 20 (20%) were KOH negative. Overall culture positivity rate was 68%. Dermatophytosis was more common in males, the M:F ratio was 4:1. Conclusion: Total seven species were isolated on culture. Trichophyton rubrum (66.17%) was the commonest isolate followed by Trichophyton mentagrophytes (19.11%), Trichophyton violaceum (7.35%), Trichophyton tonsurans (2.94%) and one isolate each of Epidermophyton floccosum and Microsporum gypseum (1.47%).

Microsporum gypseum dermatophytosis in a patient of acquired immunodeficiency syndrome: a rare case report.

Microsporum gypseum, a geophillic dermatophyte is rarely isolated from patients with acquired immunodeficiency syndrome. We report tinea corporis due to Microsporum gypseum, an uncommon aetiological agent, in a patient with acquired immunodeficiency syndrome from our region. The clinical presentation resembled psoriasis characterised by atypical, scaly and hyperkeratotic lesions.

Clinico-Epidemiological Profile, Pandemic Influenza A H1N1/2009 and Seasonal Influenza, August 2009-March 2013, Himachal Pradesh, India

Background: Novel influenza A (H1N1) virus emerged in April, 2009, spread rapidly to become pandemic by June, 2009. Objective: To study the clinco-epidemiological profile of pH1N1and seasonal influenza (SI) from 2009 to 2013. Materials and Methods : Retrospective, hospital-based study was done by reviewing medical records for collecting demographic and clinical profile of the study samples. Result: Out of 969 samples, positivity and case fatality for pH1N1 and SI was 9.39 and 20.87% vs 11.76 and 7.89%, respectively. Among pH1N1and SI, sex distribution, mean age, and age group involved were 54.95% females, 37.10 years, and 20-29 years (23.08%) vs 43.86% females, 40.32 years, and 20-29 years (22.81%), respectively. Mortality shift was observed from younger to older and healthier, 75% to comorbid, 100% from 2009-2010 to 2012-13 for pH1N1. Conclusion: We observed seasonal variation, cocirculation, similar clinical features, decreased virulence, and community spread with respect to pH1N1 and SI from 2009-2013.

A constellation of cardiac anomalies: Beyond shone's complex

Shones anomaly is a very rare congenital cardiac malformation characterized by four serial obstructive lesions of the left side of the heart (i) Supravalvular mitral membrane (ii) parachute mitral valve (iii) muscular or membranous subaortic stenosis and (iv) coarctation of aorta. We report a unique presentation of Shones complex in a 14-year-old adolescent male. In addition to the four characteristic lesions the patient had bicuspid aortic valve, aneurysm of sinus of valsalva, patent ductus arteriosus, ventricular septal defect, persistent left superior vena cava opening into coronary sinus and severe pulmonary artery hypertension. This case report highlights the importance of a strong clinical suspicion of the coexistence of multiple congenital cardiac anomalies in Shones complex and the significance of a careful comprehensive echocardiography.

Inducible Clindamycin Resistance among Clinical Isolates of Staphylococcus aureus from Sub Himalayan Region of India

INTRODUCTION Clindamycin is an alternative antibiotic in the treatment of Staphylococcus aureus (S.aureus) infections, both in infections by methicillin susceptible and resistant (MSSA and MRSA) strains. The major problem of use of clindamycin for staphylococcal infections is the presence of inducible clindamycin resistance that can lead to treatment failure in such infections. AIM To determine inducible and constitutive clindamycin resistance among clinical isolates of S. aureus in a tertiary care centre of sub Himalayan region of India. MATERIALS AND METHODS A total of 350 isolates of S. aureus from various clinical samples were subjected to routine antibiotic sensitivity testing by Kirby Bauer disc diffusion method. Methicillin resistance was detected by cefoxitin (30μg) disc. All isolates were subjected to inducible clindamycin resistance was by Clinical Laboratory Standards Institute (CLSI) recommended D test. RESULTS Among 350 S.aureus isolates, 82 (23.42%) were MRSA and 268 (76.57%) were MSSA. Erythromycin resistance was detected in 137 (39.14%) isolates. Erythromycin resistance in MRSA and MSSA was 71.6% and 29.36% respectively. Overall clindamycin resistance was seen in 108 (30.85%) isolates. Constitutive MSLB phenotype predominated (29.62% MRSA; 13.38% MSSA) followed by iMLSB (28.39% MRSA; 9.29% MSSA) and MS phenotypes (13.58% MRSA; 6.69%MSSA). Both inducible and constitutive clindamycin resistance was significantly higher (p=0.00001, 0.0008 respectively) in methicillin resistant strains than in methicillin susceptible strains. CONCLUSION The present study gives a magnitude of clindamycin resistance among clinical isolates of S. aureus from this region of the country. Our study recommends routine testing of inducible clindamycin resistance at individual settings to guide optimum therapy and to avoid treatment failure.

A case report of an uncommon phaeoid fungal infection in nasal polyposis and review of literature

Nasal polyposis is an inflammatory condition of mucous membrane of the nose and paranasal sinuses with unknown aetiology. Massive nasal polyps can obstruct the nasal cavity causing discomfort and lowered quality of life. Thus, aetiological diagnosis is important for treatment, especially in recurrent nasal polyposis. We present a rare case of pansinusitis with bilateral ethmoidal polyps caused by an unusual phaeoid fungus Fonsecaea pedrosoi in a 65-year-old immunocompetent male from a rural background. The diagnosis was made by endoscopic nasal examination; high resolution computed tomography of the paranasal sinuses, detection of fungal hyphae in 10% potassium hydroxide wet mount and culture.

Seroepidemiology of a recent outbreak of Hepatitis E in urban Shimla, Himachal Pradesh, India

Hepatitis E, a major public health problem, continues to cause epidemics in different geographic areas in India and poses multi-sectoral challenges. The aim of the study was to determine the seroepidemiology of the hepatitis outbreak in the urban areas of district Shimla, Himachal Pradesh. Patients presenting with clinical features of acute viral hepatitis during and after the epidemic period were tested for seromarkers; IgM anti-HEV and IgM anti-HAV by enzyme linked immunosorbant assay. The weekly reporting under Integrated Disease and Surveillance Programme (IDSP) for cases of jaundice from Shimla from December 2015 to April 2016 was reviewed. The outbreak of hepatitis due to contamination of drinking water supply in urban Shimla beginning December 12, 2015 was confirmed by IDSP. A total of 425 serum samples (males: 292; females: 133) were tested for IgM anti-HAV and IgM anti-HEV by ELISA. Liver enzymes where deranged in all cases. Serological evidence of infection with HAV and/or HEV was seen in 64%. HEV infection alone was detected in 62.13%. All ages were affected, with one case of HEV infection below ten years. HEV infection alone was 5 times more common than HAV infection and co-infection was detected in 69 cases (m: 47; f:22). Six antenatal mothers were anti-HEV positive and the maternal mortality of 50% (n=3) due to fulminant hepatitis. Since HAV and HEV have a similar faecal-oral route of transmission, this study highlights periodic surveillance of HAV/HEV exposure pattern to improve levels of personal and food hygiene and inter-sectoral collaboration for provision of safe water supply and safe sewage disposal.

Screening for metallo-β-lactamase producing Pseudomonas aeruginosa in clinical isolates in a tertiary care hospital in North India

Introduction: Pseudomonas aeruginosa has acquired a new metallo-β-lactamase (MBL) resistance gene responsible for increased resistance to fluoroquinolones, cephalosporins and carbapenems. Thus, it is essential to know the antibiotic sensitivity pattern and follow the antibiotic policy. Objectives: The objective of this study is to detect MBL production in clinical isolates by combined imipenem-ethylenediamine tetra acetic acid (IMP-EDTA) disc test. Materials and Methods: This study was conducted for a period of nine months from April 2011 to December 2011. A total of 66 consecutive isolates of P. aeruginosa were subjected to susceptibility testing by disc diffusion assay. IMP drug resistant strains were screened for MBL production by combined IMP-EDTA disc test. Results: Ciprofloxacin resistance was seen in 66.6% isolates followed by piperacillin in 51.5%. Resistance toward amikacin, ceftazidime, and cefoperazone were noted in 43.9%, 40.9%, and 37.8% isolates, respectively. In 37.8%, IMP resistance was observed. All IMP resistant strains (n = 25) were screened for MBL production. All the 25 isolates (100%) were MBL producers, exhibiting more than 7 mm zone size enhancement in IMP-EDTA combined disc test. Conclusion: Emergence of P. aeruginosa as MBL producer is becoming a therapeutic challenge. There is a need to implement routine antibiotic surveillance and judicious use of antibiotics.

Onychomycosis due to Aspergillus niger with concomitant multiple fungal infections in a human immunodeficiency virus infected person

Opportunistic fungal infections are common in human immunodeficiency virus (HIV) infected patients and commonly occur at some point during their illness. Though estimates show that these infections can occur in HIV patients with the same frequency as in the control group, their presentations are more severe and variable in HIV/acquired immunodeficiency syndrome. We present an HIV infected case with multiple fungal infections. This patient had onychomycosis due to Aspergillus niger, tinea cruris caused by Trichophyton rubrum, oral thrush and balanoposthitis due to Candida albicans.
