ABSTRACT
Background: Carbapenem resistance in Gram Negative Bacilli is an emerging threat in tertiary care centers which is mediated by Metallo-β-lactamase (MBL) enzyme. As per the National committee for Clinical Laboratory Standards (NCCLS), still does not have documented standard procedure from there several screening methods to detect their enzyme. Some subcontinents of India still awaiting to see prevalence and screening methods to detect enzyme which is responsible for Carbapenem Resistance. Aim: The present study was undertaken to early detection of MBL by screening methods in Gram Negative Bacilli isolated from hospital and the prevalence MBL production in carbapenem resistant bacterial isolates. Materials and methods: 176 consecutive different Gram Negative Bacilli (GNB) isolated from hospitalized patients which were tested antimicrobial susceptibility for different antibiotics including Carbapenem drugs as Imipenem by Kirby Bauer Disc Diffusion (CLSI 2010) and screening of Metallo-β-lactamase production by method as Imipenem- EDTA combined disc synergy test (ICDST) and Imipenem-Double Disc Synergy Test (I-DDST) which determine the MBL by zone size enhancement with EDTA Impregnated Imipenem.

IAIM, 2019; 6(4): 107-111. Page 108 Results: Out of 176 Gram Negative Bacilli, 20.45% (n=36) of isolates were resistance to Imipenem by disc diffusion method and 94.44% (n=34) by DDST EDTA impregnated Imipenem and 88.89% (n=32) showed enhancement of zone size ≥7 mm with EDTA impregnated Imipenem CDST. Imipenem susceptible bacteria strains did not show any enhancement with EDTA impregnated antibiotic disc. Conclusion: Critically ill patient’s therapy is cause of concern for MBL mediated imipenem resistance gram Negative Bacilli. Two methods used for supplementary support in treatment of patients. In both methods of detection DDST is more effective.
ABSTRACT
Trichosporon asahii (formerly known as Trichosporon beigelii) is an emerging, life-threatening opportunistic pathogen and has been found to be invariably associated with disseminated or deep-seated trichosporonosis, more so among the patients with granulocytopenia or hematological malignancies. We here report a successfully treated case of disseminated trichosporonosis in a known diabetic, 14-year-old girl, admitted to our hospital with chief complaints of fever, chills, and burning micturition since 3 weeks. Disseminated trichosporonosis is usually an insidious disease with poor prognosis. Early diagnosis is crucial for successful treatment. High index of clinical suspicion and extensive microbiological investigations can clinch the diagnosis.
ABSTRACT
Introduction: Injury is a major, preventable public health problem in terms of morbidity, premature mortality or disability. This study aims to assess the epidemiology of injury in patients admitted to a tertiary care centre in northern India. Materials and Methods: Observational, Descriptive, secondary data based study of injury patients admitted in surgical emergency department of Government Medical College Hospital Chandigarh from July 2009 to June 2010. Results: Out of these total 7222 patients, 4129(57.2%) were of Road Traffic Accident (RTA) and 22.8% were of Assault. Male were at high risk of RTA. Although, overall males were at higher risk of assault but middle aged women were at higher risk than their counterparts. For ‘fall ‘females were at high risk. Assault cases were more prevalent during summer, while RTA cases were more prevalent during winter season and fall during rainy season were reportedly more. Majority (33.0%) of RTA injury was in the age group of 20-39 years (most productive age) and in the age group of <10 years falls were most common (56.0% of all injury).
ABSTRACT
BACKGROUND: An outbreak of measles was reported from a slum, UT, Chandigarh in April 2003. Similar outbreak was also reported in less than three years from the same and adjoining areas. The present study was conducted to investigate and assess various epidemiological features associated with measles outbreak. MATERIAL AND METHODS: Three cases of measles were admitted in Dept. of Paediatrics, Govt. Medical College & Hospital, Chandigarh and were reported to the Dept. of Community Medicine for an outbreak investigation. A trained team investigated the slum having a population of 25,000 and studied various features associated with epidemic between the period of April 22 to May 10, 2003. RESULTS: The study covered 484 houses having 1130 children. Among the children who developed measles 32.76% were vaccinated ones. In them attack rate was 3%. Attack rate in vaccinated children went on increasing as age increased. An overall attack rate of 5.13% (Peak incidence 6% in 1-4 years age group) was recorded. Among measles cases, one-fifth had post measles complications. As much as 32.76% children with measles had received measles vaccination in the past. Therefore something more than immunization by single dose of vaccine is required. Measles was reported to be higher amongst the children without Vitamin A supplementation (P < 0.001). CONCLUSION: There is need to store vaccine properly and to strengthen routine immunization coverage, Vitamin A supplementation and health infrastructure in underprivileged population. Serological studies among vaccinated children against measles should be undertaken to explore the possibility of second dose of measles in older children.
