A Case Report of an Unusual Cause of Dysphagia from Enlarged Subcarinal Lymph Node

Cough, hemoptysis, chest pain, and weight loss are classic symptoms of bronchial carcinoma. Small cell lung cancer presents late with obviously abnormal chest radiographs and with bulky, usually mediastinal lymph node involvement. Dysphagia rarely occurs in patients with bronchial carcinoma. There are many causes of dysphagia in bronchial carcinoma such as mediastinal lymphadenopathy, direct tumor invasion of the mediastinum, radiotherapy, secondary achalasia. This report presents a case of progressive dysphagia to solid foods and weight loss of a 28-year-old male, non-smoker due to subcarinal lymph node enlargement from metastatic bronchial adenocarcinoma.

Prolonged Jaundice in a Patient with Coexisting Hepatitis A Virus Infection and Wilson's Disease

Hepatitis A virus (HAV) is the most common cause of acute viral hepatitis in the world. Infection with hepatitis A virus can cause severe or even fatal illness in patients with chronic liver disease. Here we present a case which seems to be an isolated acute viral hepatitis A infection at the beginning but later found to be coexisted with Wilson's disease. A 14-year-old girl presented in the Department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 11th April 2019 with progressive jaundice with prodrome, dark urine, itching, hepatomegaly and thyromegaly. She was found positive for serum IgM HAV antibody. Her jaundice was increasing along with prolonged prothrombin time and low albumin. She had coexisting Wilson's disease evidenced by increased 24 hours urinary copper (138μgm/day). She was treated with D-Penicillamine and Zinc acetate. Hepatitis A can be considered as a factor for acute decompensation in undiagnosed patients with Wilson's disease. So it is very crucial to investigate Wilson's disease in appropriate clinical setting of prolonged jaundice and liver dysfunction.

Study of the Prevalence of Dyspepsia in the Adult Population in a Rural Community of Bangladesh

Dyspepsia is a symptom complex that includes epigastric pain, post-prandial fullness, bloating, early satiety, belching, nausea, vomiting, heartburn, acid regurgitations and anorexia. The most widely applied definition of dyspepsia is the Rome working team formulation namely chronic or recurrent pain or discomfort centered in the upper abdomen. Till date the prevalence of dyspepsia in Bangladesh has not been studied much. The last study was done in 1987 in a rural community and the prevalence of dyspepsia was found to be 41.4%. However, associated risk factors were not assessed and definition of dyspepsia was much narrower as well as the dysmotility type dyspepsia was not included in that study. Hence it is now high time to carry out another study to see the prevalence of dyspepsia in Bangladesh and the risk factors associated with it. To determine the prevalence of dyspepsia and the demographic risk factors associated with dyspepsia in the adult population in the rural community of Bangladesh. This cross sectional population based study carried out in Ghior Union of Manikgonj district of Bangladesh from January 2007 to April 2008. All persons 18 years or above living in Ghior Union were considered as the study populations with using a pre-designed questionnaire. This study showed that the prevalence of dyspepsia to be 61.9%. Reflux- like dyspepsia was the commonest sub-type of dyspepsia without reflux symptoms comprising 43.9% of the total population and 70.9% of the dyspeptics. Dysmotility like dyspepsia comprised more than half of the dyspeptics. Nausea (40.7%) was the most predominant dysmotility like dyspeptic symptoms followed by early satiety (38.4%); 13.9% of the population had history of recurrent upper abdominal pain and 11.9% of the population had gastro-esophageal reflux disease (GERD). There was considerable overlapping (16.7%) of IBS with dyspepsia. Female sex, younger age (<40 years), low family income (<5000 Taka per month), lower educational level (up to primary level), smoking and use of NSAIDs were significantly associated with dyspepsia. The prevalence of dyspepsia in adult population of Bangladesh is 61.9% which is very high compared to other countries and also much higher than the prevalence found in our country thirty years back. A great change in the socio-economic status and lifestyle of the people along with environmental pollution and food adulteration may be responsible for this increase in prevalence. This study was conducted in only one union of this country, so it was not representative of the whole population of the country. Therefore further study with large population size including rural and urban peoples from different parts of Bangladesh is needed to estimate the accurate prevalence of dyspepsia in our country.

Evaluation of Duodenal Eosinophil Count in Adult Patients with Functional Dyspepsia

Several mechanisms have been proposed to explain the symptoms of functional dyspepsia but actual pathogenesis is still poorly understood. Recent studies support duodenal abnormality to be the most important causal link to explain symptoms and to understand abnormal pathophysiology of functional dyspepsia. The aim of this prospective observational study is to compare eosinophil count in duodenal mucosa between patients with functional dyspepsia and control subjects without dyspepsia and was done at the department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from December 2015 to December 2016. Total 42 patients of functional dyspepsia based on Bangla validated version of ROME III criteria and 42 controls who were referred for upper gastrointestinal endoscopy for reasons other than dyspepsia were included. Biopsy specimens were collected from the second part (D2) of the duodenum of all participants. Eosinophil count was quantitatively evaluated by hematoxylin and eosin staining and expressed in numbers per 5 HPF. Significantly increased duodenal eosinophil count was found in functional dyspepsia group than non dyspeptic patients (22.78±08.78 vs. 14.90±10.70, p=0.001). Higher duodenal eosinophil count was found in patients with postprandial distress syndrome. Increased duodenal eosinophil count was found in patient of functional dyspepsia. It requires further large scale multicenter studies to establish duodenal eosinophilia as a biomarker of functional dyspepsia.

Celiac Disease in Patients Fulfilling the Rome III Criteria for Irritable Bowel Syndrome Attending Gastroenterology Department of A Tertiary Care Hospital in Bangladesh

Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder that substantially affects patients' quality of life and is associated with a considerable drain of health-care resources and economic burden. But some IBS patients may have celiac disease that could be treated by gluten-free diet which will subsequently improve their quality of life. This study was done to see the prevalence of celiac disease among the IBS patients fulfilling Rome III criteria. The present cross-sectional study was conducted in the Department of Gastroenterology at BSMMU, Dhaka from July 2010 to September 2011. A total of 107 patients aged ranging between 16-60 years clinically labeled as IBS and fulfilled Rome III criteria were included as study sample. The test statistics used to analyze the data were descriptive statistics. The mean age of the patients was 31.5±10.3 years and male to female ratio was roughly 6:1. The mean duration of IBS was 32.0±2.1 months. All of the patients had abdominal discomfort or pain in the preceding 6 months and had a history of loose (mushy) or watery stool, 99.1% had pain or discomfort relieved with defaecation. The prevalence of diarrhoea was found in 78.5% and mixed 21.5% of the patients. About 5% of the patients had raised ESR and majority (86.9%) of the patients had normal level of hemoglobin. Ten (9%) of 107 patients were found positive for anti-t TG (IgA). These findings suggest that an around one-tenth of IBS especially diarrhoea predominant patients may have celiac disease who will respond to simple gluten-free diet thus minimizing the morbidity and mortality. So, all clinically diagnosed IBS patients especially diarrhoea predominant cases should be suggested for the screening for celiac disease.

Efficacy of adefovir dipivoxil therapy in patients with chronic hepatitis B viral infection

Hepatitis B virus (HBV) infection is a major public health problem in the world. About 30% of world population has serological evidence of HBV infection. The prevalence of chronic hepatitis B in Bangladesh is reported to be 7.8%. Several potentially effective agents with different mechanisms of action have entered clinical practice and adefovir dipivoxil is one of them. Studies on the efficacy of adefovir dipivoxil in Bangladeshi patients are lacking. This was a prospective study to find out the effect of one year adefovir therapy in patients with chronic hepatitis B virus infection who were HBeAg positive. Total number of patients included in this study was 68. Among them 53(77.94%) patients continued the therapy and completed follow up. At the end of one year of therapy, intention to treat analysis showed that the rate of response (HBeAg seroconversion and HBV DNA negative) was 37.73% which was comparable to the results obtained in other studies. There was major difference in the pre treatment serum ALT level between the responders and non-responders. Comparison of reduction of serum ALT level before treatment and after treatment showed that ALT level to be lower in both responder group and non responder group. Adefovir was effective in replicative HBV infection in Bangladeshi population. So we suggest that treatment can be started and subsequent follow up can be done in chronic HBV patients who are HBeAg positive without liver biopsy.

Disease extent and local complication of ulcerative colitis in Bangladeshi population

Ulcerative colitis may involve anywhere from the rectum alone to the entire colon. Local complications like perforation, life threatening haemorrhage, toxic megacolon, pseudo polyps, stricture, and carcinoma of colon are seen. Patients who were diagnosed as Ulcerative Colitis in Departmental Ulcerative Colitis record book from January 1990 to June 2010 was considered as study population. Information regarding the extent of the disease and local complications were taken from earliest documented Lower GIT Endoscopy. Out of 164 patients disease extent were seen in 126(76.83%) patients and among them proctitis/proctosigmoiditis were seen in 57(45.24%) patients, left sided colitis were seen in 11(8.73%) patients, extensive/pan colitis were seen in 58(46.03%) patients. Complication were seen in 164 patients and 1(0.60%) patient had life threatening haemorrhage, 25(15.24%) patients developed pseudo polyps. There was no report of perforation, toxic megacolon, stricture or carcinoma of colon. The differences found between our study and studies from other Western and Asian countries in terms of complication rate and disease extent for were probably due to low index of suspicion, incomplete workup, or incomplete records, and influence of various environmental factors. So, further large scale prospective evaluation is suggested.

Efficacy of Peppermint oil in diarrhea predominant IBS - a double blind randomized placebo - controlled study

Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorder which is associated with considerable sufferings of patient and Peppermint oil is volatile oil, its active principle is menthol-contain a cyclic monoterpine which has anti-spasmotic properties due to its ability to block calcium channel of intestinal smooth muscles. This study observed the efficacy of peppermint oil for relieving the symptoms and changes of quality of life (QOL) in diarrhea predominant IBS. This was a prospective double blind randomized placebo-controlled study conducted in the Bangabandhu Sheikh Mujib Medical University during July 2008 to September 2009. Patients who fulfilled ROME II were initially selected but those had red flag signs or any organic disease was excluded from the study. Seventy four patients were enrolled in the study and randomly allocated to receive either peppermint oil or placebo three times daily for six weeks. Changes of symptoms were assessed three week interval during treatment and two weeks after the end of treatment. Data were analyzed by paired and unpaired 't' test. Finally sixty five patients completed the trial. It was observed that, at six weeks of therapy abdominal pain is markedly improved (mean±SD) 4.94±1.30 in peppermint oil group compared with 6.15±1.24 in placebo group and the difference was statistically highly significant (p>0.001). But two weeks after end of trials pain score again increased (6.09±1.93). Other symptoms and quality of life did not improve significantly. So the study result concludes that peppermint oil is effective in reliving only abdominal pain in diarrhea predominant IBS transiently.

Clinicopathological profile of patients with abdominal tuberculosis

BACKGROUND

Tuberculosis (TB) is not a uncommon problem throughout the world particularly in the developing countries like Nepal, India and Bangladesh. Abdominal Tuberculosis accounts for nearly 2% of tuberculosis worldwide. The aim of this study was to evaluate the clinicopathological profile with the help of other investigations in the diagnosis of patients with abdominal TB and their response to anti-tubercular therapy. This was a prospective cross-sectional study conducted in the department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of October 2002 to June 2009.

METHODS

Total 53 patients with abdominal TB diagnosed on the basis of clinical profile and supported investigation data like gross morphological findings at endoscopy, colonoscopy, diagnostic laparoscopy , laparotomy or histologically proven caseating granulomas were selected for this study. Detailed demographic, clinical profile, investigations and treatment response were recorded properly in a predesigned data collection sheet which were analyzed and compared with other studies.

RESULTS

Out of the 53 patients, 33 were males and 20 females with age ranging 16-70 (Mean 30.01±11.7) years. Abdominal pain was the most common presenting symptom in 47 (88.68%), fever in 45 (84.9%) and weight loss in 37 (69.81%) cases. Anemia was found in 41 (77.36%), cachexia 40 (75.47%), ascites 20 (37.74%), palpable abdominal mass in 14 (26.42%) and features of intestinal obstruction in 5 (9.43%) cases. Five patients had positive family history of TB and five had past history of pulmonary TB. The diagnosis of abdominal TB was confirmed microscopically in 5 (9.43%), histopathologically in 31 (58.49%) and the remaining 17 (32.07%) cases were diagnosed by a positive response to anti-TB therapy. According to site of involvement, 31 (58.51%), patients had intestinal TB, 9 (16.98%) had peritoneal TB and disseminated TB in 20 (37.74%) of the case. Twenty seven patients were given 3 drugs regimen for 12 months and 26 patients received 4 drugs regimen for 9 months under close supervision. By 9 months of therapy 51 patients become symptom free and no pathological findings were observed thereafter at follow up visits after 6 months. Response was not satisfactory in two patients and subsequent follow up investigation revealed to have crohn's disease rather than TB and none of them died.

CONCLUSIONS

Abdominal TB is an important clinical entity having varied mode of clinical presentation. So the diagnosis of abdominal TB is difficult and careful approach to the patients and supportive investigation data are necessary to make the final diagnosis. Neither clinical features, laboratory, radiological and Endoscopic methods nor bacteriological and histopathological findings by themselves provide a gold standard in the diagnosis of abdominal TB. In this series of abdominal TB, intestinal TB was the most frequent clinical type and the common presenting symptoms were abdominal pain, fever and weight loss. If diagnosed early, it can be treated successfully with anti-TB drugs.
