ABSTRACT
Background: Geographical variation in the distribution of Malassezia species associated with pityriasis versicolor (PV) has led to the necessity of studying epidemiological, mycological, and clinical characteristics of PV. Aims: To study the epidemiological, mycological, and clinical characteristics of PV in a tertiary care hospital. Settings and Design: The study was carried out with a cross‑sectional design. Materials and Methods: Two hundred and sixty‑two consecutive PV patients were subjected to detailed history, clinical examination, and investigations. Skin scrapings were processed by direct microscopy and culture. Isolates were identified by phenotypic characteristics and polymerase chain reaction‑restriction fragment length polymorphism. Association of Malassezia species with clinical and epidemiological characteristics was studied. Statistical analysis of the data was done using statistical software. Results: Maximum number of PV cases (33.9%) belonged to the age group of 21–30 years with a male preponderance. 61.4% of the patients had a sedentary lifestyle, 70.2% showed the gradual onset of the disease, 51.1% presented with pruritus and in 66.4% of the patients symptoms were continuous. Most commonly involved body site was neck (27.8%), 77.09% of the lesions were bilaterally asymmetrical, 87.4% were macular, and 89.3% were hypopigmented. Malassezia furfur (77.3%) was the predominant species. Sedentary lifestyle (61.4%) and increased sweating (48%) were the most commonly associated predisposing factors. Conclusion: PV is more common in males. Distribution of Malassezia species varies significantly from those reported in other parts of India. M. furfur was the most common species responsible for PV in our region. Hence, further studies are required to evaluate the exact cause of this variation.
ABSTRACT
Aim: This study was carried out to determine the presence of blaTEM, blaSHV and blaCTX-M genes in extended-spectrum β-lactamase (ESBL) producing Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) at a tertiary care referral hospital in Northeast India. Materials and Methods: A total of 270 E. coli and 219 K. pneumoniae isolates were recovered during the period between August 2009 and July 2010. Kirby-Bauer disk diffusion method was performed to determine the antibiotic resistance pattern. Screening and phenotypic confi rmatory test for ESBL production were performed using standard disc diffusion methods. Each of the initial ESBL screening test isolate was investigated for the presence of blaTEM, blaSHV and blaCTX-M genes via polymerase chain reaction (PCR) using gene-specifi c primers. Results: P henotypic confi rmatory test able to detect ESBL production in 73.58% of E. coli and 67.24% of K. pneumoniae. However, PCR amplifi cation showed the presence of one or more ESBL genes in each of the initial ESBL screening positive isolate. Among three ESBL genotypes, the most prevalent genotype was found to be blaCTX-M in E. coli (88.67%) and blaTEM in K. pneumoniae (77.58%) ESBL producing isolates. Majority of ESBL producing isolates possess more than one ESBL genes. Conclusion: T his study constituted a primer report on high prevalence of blaTEM and blaCTX-M genes in ESBL producing isolates of E. coli and K. pneumoniae and denotes the need of more extensive studies on these antibiotic genes to determine the magnitude of the problem of antibiotic resistance exiting in this locality.
ABSTRACT
A number of pharmacological approaches as well as psychological interventions are effective in the treatment of obsessive-compulsive disorder [OCD]. The present study was conducted to see the relative efficacy of treatment approaches. 30 diagnosed cases of OCD were taken and divided into two groups. Each group consisted of 15 patients. Group A [N=15] received Capsule Fluoxetine and Group B [N=15] received Capsule Fluoxetine and CBT [13 weekly sessions]. Twenty six participants completed the study [13 in each group]. Dhaka University Obsessive-compulsive Scale [DUOCS] was used to measure the symptom severity. Symptom scores were measured at weeks 1, 5, 9 and 13. After 13 weeks, analysis of the data was done and the means of initial DUOCS score and 13th week score were compared. In both the groups the mean score changes were highly significant [p=0.000]. Intra group analysis revealed that both the treatment approaches were highly efficacious. Inter-group analysis revealed that the response in combination group was significantly higher starting from 9th week, continuing up to 13th week. Mean symptom reduction and mean percentage reduction of symptoms were also higher in the case of combination group

Background & objectives Endothelial nitric oxide is a potent vasodilator and impairment of its generation brought about by gene polymorphism is considered a major predictor for several diseases. A single nucleotide polymorphism G894T within exon 7 of endothelial nitric oxide synthase (eNOS-7) gene, resulting in a replacement of glutamic acid by aspartic acid, has been studied as a putative candidate gene for cardiovascular diseases. The pattern of eNOS-7 Glu298Asp variant in the Indian population is poorly known. The present study was planned to determine the prevalence of the variant of this gene among tea garden community in Assam, North-East India with high prevalence of hypertension. Methods Study participants of both sex aged ≥18 yr were recruited randomly from temporary field clinics established in tea gardens of Dibrugarh, Assam. Genomic DNA was extracted from 409 subjects by the conventional phenol-chloroform method. The prevalence of the eNOS exon 7 Glu298Asp variant was determined by polymerase chain reaction and restriction fragment length polymorphism analysis. Results The study population was in Hardy-Weinberg Equilibrium. The frequency of the eNOS GG, GT and TT genotypes was found to be 75, 22 and 3 per cent respectively and did not show any significant difference in gender wise analysis. Interpretation & conclusions Our results showed that the prevalence of the homozygous GG genotype was high (75%) and the rare mutant genotype (homozygous, TT) was 3 per cent in a population at risk with cardiovascular disease. Such population-based data on various polymorphisms can ultimately be exploited in pharmacogenomics.
