Peptic Ulcer Disease in Bangladesh: A Multi-centre Study

The incidence of peptic ulcer has steadily declined through out the world. This decreasing trend is also noticeable in this subcontinent. The point prevalence of peptic ulcer (PUD) in Bangladesh was around 15% in eighties. The aim of this study was to see the present prevalence of peptic ulcer at endoscopy and to identify changing trends in the occurrence of peptic ulcer in Bangladesh. This retrospective analysis of the endoscopic records of multiple tertiary referral centres of Dhaka city were done from January 2012 to July 2013. A total of 5608 subjects were the study samples. We included those patients having peptic ulcer in the form of duodenal ulcer, benign gastric ulcer including pre-pyloric ulcer and gastric outlet obstruction due to peptic ulcer. Duodenal ulcer and benign gastric ulcer were found in 415(7.4%) and 184(3.28%) patients respectively and gastric outlet obstruction due to peptic ulcer was found in 23(0.40%) patients.

Pattern of Changes in the Findings among the Patients Undergoing Diagnostic Esophagogastroduodenoscopy in Bangladesh

This cross-sectional observational study was conducted in the Department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University, Sir Salimullah Medical College and Mitford Hospital, Holy family Red Crescent Medical College and Hospital and Popular Diagnostic Centre, Shantinagar branch, Dhaka, Bangladesh from January 2012 to July 2013. Study subjects were included in the study irrespective of age and sex having different upper GI tract. Complaints like dysphagia, heart burn, abdominal pain/dyspepsia, nausea, vomiting, haematemesis and/or malena, anorexia, unexplained anemia, weight loss etc. All the findings of oesophagus, stomach and duodenal lesions were observed and data were recorded. The results were considered positive based on the macroscopic appearance using standard diagnostic criteria. During the study period endoscopy was performed in 5608 subjects. Among which 2968(52.92%) were male and 2640(47.07%) were female. The patients age range from 7 years to 108 years. The majority of the patients were from 40-50 years. Normal findings were observed among 3321(59.21%) cases. Gastroduodenal erosions were present among 684(12.19%) cases, Oesophageal varices in 444(7.91%) cases, duodenal ulcer diseases in 415(7.40%) cases and gastric ulcer in 184(3.28%) cases. Ca stomach was found among 165(2.94%) cases. A number of diseases were identified through this procedure. Current study observed a large proportion of patients (40.79%) had positive upper GI endoscopy.

Pigtail Catheter in the Management of Liver Abscess

Amoebic liver abscess is a common condition in Bangladesh. Though conservative treatment plays a major role, refractory patients can be successfully treated with minimally invasive approach. This prospective study was carried out to evaluate the prospect of sono-guided percutaneous catheter drainage for liver abscess patients not responding to conservative treatment. This study was done at Dhaka Medical College Hospital from January 2005 to June 2006 among patients with liver abscess that were treated conservatively outside and got admitted in different surgery and medicine units. Included 35 patients were evaluated clinically and through relevant investigations. Sono-guided percutaneous pigtail catheter was introduced for drainage and patients were followed up for two weeks on average at hospital indoor by amount of drainage, clinical improvement and serial follow up USG. After discharge from the hospital, all patients were followed up monthly and assessed clinically and ultrasonographically up to two months on outdoor basis. Thirty five patients underwent pigtail catheter drainage that was refractory to conservative treatment or needle aspiration. Following insertion of catheter patients who were pyrexic, fever subsided in two to three days and never back during the postoperative period and follow up. Antimicrobials were changed according to the report of the culture and sensitivity of the aspirate that was done routinely. Maximum total (4300 ml) amount of pus was drained in a patient. Average duration of catheter drainage in this study was 8 days. With a very low morbidity and zero mortality rates, minimum treatment costs and early return to regular life style proved this minimally invasive procedure to be a rational treatment option for amoebic liver abscess in selective cases.

Evidence for a link between locus R-R sequence type and outcome of infection with Entamoeba histolytica

The results of Entamoeba histolytica infections range from asymptomatic colonization to variable disease outcomes. However, markers that may predict infection outcomes are not known. Here, we investigated sequence types of a non-coding tRNA-linked locus R-R to identify surrogate markers that may show association with infection outcomes. Among 112 clinical samples--21 asymptomatic, 20 diarrhoea/dysentery and 71 liver abscesses--we identified 11 sequence types. Sequence type 5RR was mostly associated with asymptomatic samples, and sequence type 10RR was predominantly associated with the symptomatic (diarrhoea/dysentery and liver abscess) samples. This is the first report that identifies markers that may predict disease outcomes in E. histolytica infection.

A delayed presentation of cardiac tamponade after blunt trauma

Cardiac tamponade is a recognised complication of blunt trauma to the chest. It usually presents at the time of the acute event but there are rare cases of delayed presentations. We present such a case where the tamponade occurred six weeks following the trauma to the chest wall.
