Drowning has been identified as a major cause of death in children in both developed and developing countries. Non-fatal drowning is several times higher than the fatal drowning. To describe the socio-demographic and environmental attributes of non-fatal drowning in rural children this community based descriptive study was conducted on 122 children having non-fatal drowning events within one year of study period. This study was undertaken in Raigonj sub-district of Sirajgonj district in Bangladesh. Mothers of those children were interviewed using a structured questionnaire. Out of all participants 56.6% children were 2-4 years of age and male-female ratio was almost equal. Of the total respondent mothers 55% were illiterate and 41.8% were below the age of 25 years. Seasonal variation was observed in non-fatal drowning. Rainy season (50.8%) appeared as the most risky period followed by summer (29.5%). Higher incidence occurred (53.3%) between 10 am to 2 pm of the day. Although most of the drowning occurred outside the home, 9% drowning occurred in water container (like drum, tub) within the home. Pond (50.5%) was found as the most common place among open water source. During the occurrence, 23% child was not accompanied by parents or any caregivers. At the time of drowning, 47.5% mothers were engaged with usual household work and were not present at the place of occurrence whereas 13% mothers were present around the place of occurance. Before drowning, 45.1% victim was either playing, bathing or swimming in the water. Only 10.7% needed resuscitation, 25% were taken to health centre and reached the health centre within an hour, about a fifth (22.6%) of them were admitted. Restriction in dangerous water activities, strengthening supervision of children might decrease the incidence of drowning while quick and effective medical response might prevent its fatal consequences.

Extended spectrum beta lactamases (ESBLs) produced by Gram negative bacteria are mainly mediated by three important genes, namely TEM, SHV and CTX-M. In this study, we used a multiplex PCR to determine the prevalence of CTX-M and its subgroups CTX-M-3, CTX-M-14, among the members of Enterobacteriaceae family and in Pseudomonas spp that were isolated from different clinical samples in a tertiary care hospital in Bangladesh. A total of 300 culture positive clinical isolates were selected for the study. Out of these, 216 from urine, 45 from wound swab, 39 from pus aspirates. The ESBL status was determined by double disc diffusion test (DDDT) as recommended by Clinical Laboratory Standard Institute 2010 (CLSI) and by multiplex PCR for TEM, SHV and CTX-M, CTX-M-3, CTX-M-14 genes. Out of 300 isolates tested, 71.3% were positive for ESBL production by DDDT. The rate of positivity for TEM, SHV and CTX-M genes in 107 randomely selected isolates was 83.2%. Among these, 56.2% (50/89) was positive for CTX-M. Among the CTX-M positive isolates, CTX-M-3 and CTX-M-14 were 78.0% (39/50) and 80.0% (40/50) respectively. Our study demonstrated that CTX-M variants were common in Enterobacteriaceae and Pseudomonas spp prevalent in the hospital of Bangladesh. Ibrahim Med. Coll. J. 2015; 9(1): 26-30
Melioidosis is an infectious disease that can cause serious morbidity and may result in death if not treated early. Its causative organism, Burkholderia pseudomallei is present in soil and water. Here, we report a case of disseminated melioidosis involving skin and joint in a farmer residing in an area where the organism has been found in the soil. Ibrahim Med. Coll. J. 2015; 9(2): 55-57
Carbapenem resistant Enterobacteriaceae (CRE) is becoming a major public health concern globally. Detection of carbapenem hydrolyzing enzyme carbapenemase in Enterobacteriaceae is important to institute appropriate therapy and to initiate preventive measures. This study was designed to determine the presence of carbapenemase producers among the CRE isolated from patients at Dhaka Medical College Hospital, Bangladesh. Twenty-nine CRE strains detected by disk diffusion technique were included in the study. Minimum inhibitory concentration of imipenem and tigecycline was determined by agar dilution method. Carbapenemase production was phenotypically detected by Modified Hodge test while MBL producers were detected by combined disk and double disk synergy tests. Genes encoding blaNDM-1, blaOXA-181, blaOXA-48, blaKPC, blaCTX-M-15, blaOXA-1-group were identified by polymerase chain reaction (PCR). Out of 29 CRE, nineteen (65.6%) were positive for carbapenemase by any of the three phenotypic tests namely MHT, CD or DD tests. Those 19 isolates were also positive either for blaNDM-1 or blaOXA-181/blaOXA-48 by PCR. Of the 19 PCR positive isolates, the rate of positivity for blaNDM- 1, blaOXA-181/blaOXA-48 and blaNDM-1+ blaOXA-181/blaOXA-48 was 73.7% (14/19), 57.9% (11/19) and 31.6% (6/19) respectively. Both blaOXA-181 and blaOXA-48 co-existed. All the carbapenemase producing organisms harboured blaCTX-M-15 except one C. freundii strain. The rate of resistance to different classes of antibiotics ranged from 63.2% to 100% except colistin and tigecycline. Organisms positive for OXA-181/OXA-48 had a low level of resistance to carbapenem (MIC 1 - 4 ì g/ml) while with NDM-1 had high level resistance to imipenem (MICs 16 - ? 32 ì g/ ml). Out of 19 carbapenemase positive isolates, 12 (63.16%) were extensively drug-resistant (XDR) and were only sensitive to tigecycline and colistin. The result of this study showed the presence of blaOXA-181/ blaOXA-48, blaNDM-1 positive strains in Bangladesh and colistin and tigecycline were the most effective drugs against carbapenemase producing Enterobacteriaceae (CPE). Epidemiological monitoring of carbapenemase producing organisms in Bangladesh is important to prevent their dissemination.Ibrahim Med. Coll. J. 2015; 9(2): 45-51
Inflammatory fibroid polyp is a benign and non-neoplastic condition of the gastro-intestinal tract, commonly affecting the gastric antrum, though it can affect any part of the gastro-intestinal tract. It is a submucosal, sessile, polypoid mass composed of myofbroblast like mesenchymal cells, numerous small blood vessels and marked inflammatory cell infiltrate mainly eosinophils. It commonly presents with intestinal obstruction or intussusception. We present here a case of recurrent episodes of small intestinal sub-acute obstruction due to intermittent intussusception associated with inflammatory ûbroid polyp of jejunum. Ibrahim Med. Coll.
