Bedside Index of Severity in Acute Pancreatitis (BISAP) Score on Outcome of Patients Presenting with Acute Pancreatitis in a Tertiary Care Hospital.

Background Acute pancreatitis is a life-threatening condition characterized by inflammation of the pancreas causing intense abdominal pain and potential harm to multiple organs. The mortality rate is 1-5% and thus requires specialized and interdisciplinary care to inhibit it. Objective To describe the bedside index of severity in acute pancreatitis score on the outcome of acute pancreatitis patients in a tertiary care hospital. Method This is a hospital based observational cross-sectional study conducted in the internal medicine inpatient department of Dhulikhel Hospital from April 2018 and March 2019. This study reviewed the medical records of the department. Result The study included 70 participants with 44 (±14) years of average age and stating common cause as gallstone (45.7%). The study showed that those with bedside index of severity in acute pancreatitis score ≥ 3 during hospital admission had significantly higher rate of organ failure (p-value < 0.05), as well as had a prolonged hospital stay (mean: 20 [±7.9] days). The mean hospital stay was 12.9 days. Conclusion Patients with bedside index of severity in acute pancreatitis score greater than three at admission were found to have an increased risk of organ failure, significantly higher chances of requiring mechanical ventilation, and a longer duration of hospital stay.

Rickettsial Infection amongst Febrile Illness Patient in a Tertiary Care Hospital: A Retrospective Cross-sectional Study.

Background Rickettsial infection is an emerging neglected tropical disease in the Southeast Asia. In past few years Nepal is also reporting escalating prevalence of rickettsia. The under evaluation is resulting it as undiagnosed or are simply labeled as pyrexia of unknown origin. Objective To find out the prevalence of rickettsia in a hospital setting, assess the sociodemographic and other relevant clinical features of the rickettsia patients. Method This is a hospital based retrospective cross-sectional study from October 2020 to October 2021. This study reviewed the medical records of the department. Result The study included 105 eligible patients and the prevalence rate was 4.38 per 100 patients. The mean age of the participants was 42 years, and the mean hospital stay was 3 (SD ±2.06) days. More than 55% of the participants had fever for less than or equal to 5 days and 9% had Eschar present. Vomiting, headache, and myalgia were the most common symptoms and hypertension, and diabetes were the common comorbidities. Pneumonia and the acute kidney injury were the two complications of the patients as stated in the study. The severity of the thrombocytopenia deducted from admission time to discharge, and the case fatality was 4%. Conclusion The future studies shall consider on collaborative clinical and entomological research. This would help in better understanding of the etiology of supposedly unknown febrile illness and the under-investigated field of emerging rickettsia in Nepal.

The role of laboratories in animal-related disasters and emergencies.

This paper outlines the role of laboratories in animal-health-related disasters and emergencies, with a particular focus on biological threats - intentional, accidental and natural. Whilst multisectoral coordination is increasingly recognised as necessary for effective preparedness and response to all kinds of disasters, the role of the laboratory is often overlooked. The laboratories' involvement, not just in the response, but across all phases of disaster management - mitigation, planning, response and recovery - is essential, not only for improved animal health but for preservation of livelihoods and for food security, social cohesion and economic stability.

Les auteurs examinent le rôle des laboratoires dans les catastrophes et les urgences affectant les animaux, en se centrant particulièrement sur les menaces biologiques (qu'elles soient intentionnelles, accidentelles ou naturelles). Si la nécessité d'une coordination multisectorielle pour une préparation et une intervention efficaces face aux catastrophes de toute nature est désormais mieux perçue, le rôle des laboratoires est souvent négligé. La participation des laboratoires est essentielle, non seulement dans les interventions mais aussi dans chacune des phases de la gestion des catastrophes, à savoir l'atténuation, la planification, l'intervention et le redressement et ce, non seulement pour améliorer la santé animale, mais aussi pour préserver les moyens de subsistance et la sécurité alimentaire, la cohésion sociale et la stabilité économique.

Los autores exponen a grandes líneas la función que cumplen los laboratorios frente a desastres o emergencias que guardan relación con el mundo animal, prestando especial atención a las amenazas biológicas, ya sean de origen natural, accidental o intencionado. Mientras que por un lado se asienta cada vez más la idea de que la coordinación multisectorial es indispensable para una eficaz labor de preparación y respuesta ante todo tipo de desastres, a menudo se pasa por alto la función que en la materia incumbe a los laboratorios. Es esencial que estos participen no solo en las labores de respuesta, sino en todas las fases del proceso de gestión de desastres (mitigación, planificación, respuesta y recuperación), y ello no solo para mejorar la situación zoosanitaria, sino también para preservar los medios de sustento y proteger la seguridad alimentaria, la cohesión social y la estabilidad económica.

Investigating the Efficacy of Triple Drug Therapy and Sequential Drug Therapy in the Eradication of Helicobacter Pylori with Respect to Antigen Stool test: A Pilot Study.

Background Helicobacter pylori is one of the most prevalent infectious disease worldwide. The treatment regimens involve mainly two therapies: Standard Triple drug therapy and Sequential drug therapy. Several studies have shown that the sequential therapy has higher eradication rates of H. pylori than the standard triple drug therapy and since proper study on sequential drug therapy and standard triple drug therapy is still lacking in Nepal, this study is attempted to compare efficacy of Sequential Drug Therapy in the eradication of H. pylori in gastritis with respect to the Standard triple drug therapy. Objective To investigate the efficacy of Triple Drug Therapy and Sequential Drug Therapy in the eradication of Helicobacter pylori with respect to Antigen Stool test. Method This study was the prospective study conducted in 62 patients attending the Department of Gastroenterology, Dhulikhel Hospital, meeting the inclusion criteria who were confirmed as H. pylori positive by histopathology and stool antigen test. Patients were randomized into two groups. One group prescribed with Standard triple drug regimen and another group with Sequential drug regimen. Eradication of H. pylori infection was confirmed by repeating the stool antigen test at least five weeks after the completion of the regimen. Result Among the 62 participants included in this study, 54.5% of them were males. Among the study population, the eradication achieved by standard triple drug therapy was 87.8% and 89.6% with Sequential drug therapy. Higher numbers (82.3%) of patients were compliant to the prescribed medication. Forgetfulness was the main reason for missing the dose (91%) of the non-compliant patients. Conclusion The study revealed an equal efficacy of both Standard Triple drug regimen and Sequential drug regimen in the eradication of H. pylori infection. Further, Stool antigen test can be preferred as a non-invasive test, for diagnosis of H. pylori infection, monitoring the response to treatment and in epidemiological studies.

Endoscopic Management of Foreign Body Impaction in the Upper Gastrointestinal Tract in a Tertiary Care Centre of Nepal.

Background Ingested foreign body impaction on upper gastrointestinal tract is common incidence among children, older age group, mentally challenged individuals, and people the influence of alcohol. In most cases, the foreign bodies pass spontaneously and uneventfully but when this does not occur; endoscopic management to ensure removal under direct visualization is required. Relief upon removal of foreign body and prevention of complications is essential. Objective To assess the endoscopic management and outcome of foreign body impacted in the upper gastrointestinal tract. Method This is a hospital based observational retrospective cross sectional study involving 165 patients at Endoscopy Department of Dhulikhel Hospital in Nepal between November 2015 and October 2019. The data regarding the demographic profile, clinical characteristics and endoscopic findings were retrieved and analyzed to determine endoscopic interventions performed, complications and outcomes. Result One hundred and sixty five patients presenting with history of ingestion of foreign body were included in the study. The mean age of the patients was 46.8 ± 19.1 years with male predominance (60%). The most common site of foreign body impaction was oesophagus (70%). The most common foreign body encountered was bone (62.2%) among which chicken bones (91.1%) were most frequent. For the retrieval of sharp-pointed foreign bodies, rat forceps and graspers (45.7%) were most commonly used. Total 14 cases required rigid oesophagoscopy as the foreign body could not be retrieved by flexible endoscopy. Conclusion Foreign body ingestion and its impaction in the upper gastrointestinal tract has been found to be common in endoscopic practise. Early detection and timely removal of foreign bodies is of utmost importance to avoid discomfort to the patient as well as to ensure successful removal without complications.

Outcomes of Endoscopic Sphincteroplasty Using Large Balloon Dilatation for Difficult Common Bile Duct Stone Removal at Dhulikhel Hospital.

Background Endoscopic sphincteroplasty (ESPT) using a large Controlled Radial Expansion (CRE) Wire guided balloon dilatation has gained acceptance in removing a difficult common bile duct (CBD) stones. Objective To evaluate effectiveness and complications of removing large and difficult bile duct stones with sphincterotomy combined with large balloon dilatation. Method A total of 132 patients, from February 2014 to June 2017, who had biliary ductal calculus which was either greater than 15 mm or difficult to remove with standard technique, underwent Endoscopic Retrograde Cholangiopancreaticography (ERCP) with Endoscopic sphincteroplasty using a large Controlled radial expansion wire guided balloon dilatation. The success rate of complete stone clearance and post Endoscopic Retrograde Cholangiopancreaticography complications were analyzed. Result There were 48 (36.4 %) male and 84 (63.6%) female patients with mean age of 55.48 ± 16.36 years. Stones were removed with sphincteroplasty in first attempt in 90 out of 132 (68.2%) patients, 26 out of 37 (70.27%) patients in second session and in all 7(100%) patients in third attempt. Five (11.90%) patients were lost to follow up and 4 were advised for surgery because of failure to remove stones by sphincteroplasty. Overall success of endoscopic sphincterotomy and large balloon dilatation in our study was 93.18%. Complications were seen in 17 (13.6%) patients; bleeding seen in 9 (6.8%) patients and mild pancreatitis in 8 (6.1%) patients. None of the patients had severe pancreatitis or perforation secondary to the procedure. Conclusion Endoscopic sphincteroplasty after sphincterotomy is an effective and safe technique for a difficult common bile duct stone removal.

Where is the Perforation ? Rare Complication of Endoscopic Retrograde Cholangio Pancreatography.

Perforation is one of the most feared complications of Endoscopic Retrograde Cholangio Pancreatography (ERCP). ERCP has become important method for treating biliary-pancreatic diseases. Perforation related with Endoscopic Retrograde Cholangio Pancreatography is an infrequent, but if happens is a severe complication. Reported incidence of Edoscopic Retrograde Cholangio Pancreatography related perforation is 0.3-6%. Its mortality is as high as 37.5%. In our hospital since 2010 AD, There were 6 Perforations related to Endoscopic Retrograde Cholangio Pancreatography done in 4787 cases. This is a case of Endoscopic Retrograde Cholangio Pancreatography related perforation with no site of perforation recognized during surgical management.

The Etiology of Upper Gastrointestinal Bleeding in Patients with Liver Cirrhosis in Dhulikhel Hospital.

Background Acute upper gastrointestinal bleeding is a serious medical problem in cirrhotic patients. Patients with cirrhosis may develop upper gastrointestinal bleeding from a variety of lesions, including those due to portal hypertension, namely gastroesophageal varices and portal hypertensive gastropathy and other lesions as seen in the general population. Objective To investigate the etiology of upper gastrointestinal bleeding in liver cirrhotic patients. Method A retrospective review of 72 patients with liver cirrhosis and upper gastrointestinal bleeding from January 2013 to March 2016 was carried out at Dhulikhel Hospital. Child Pugh score was used to assess severity. Endoscopic diagnosis was documented. Result Out of 72 patients, 56 (77.8 %) were male and 16 (22.2%) were female. The most common age group was 30-42 years age. Fifty four cases of cirrhosis were associated with alcohol consumption. The Child-Pugh score was A in 20 patients (27.8%), B in 15 patients (20.8%) and C in 37 patients (51.4%). A combination of alcohol consumption and HCV infection was significantly associated with a higher Child-Pugh score (p=0.031). Twenty six (36.11%) patients had esophageal varices as cause of bleeding on endoscopic examination while 29(40.28%) had varices and other lesions identified at endoscopy. Of these 29 patients, 18 were found to have bled from esophageal varices, and 11 were found to have bled from coexisting lesion. Conclusion We found that variceal bleeding was the commonest cause of bleeding in cirrhotic patients, with 55 (78.5%) having varices and 44 (61%) actually bleeding from varices.

Medication Adherence Pattern and Factors affecting Adherence in Helicobacter Pylori Eradication Therapy.

Background Helicobacter pylori (H. pylori) infection is the most common chronic bacterial infection worldwide affecting approximately half of the world's population. A number of screening tests as well as complex multi-drug therapies are available for the detection and treatment of H. pylori infection. However, the optimum eradication rates of H. pylori infection can only be achieved if adherence to drug therapy is higher. Therefore, it is of utmost importance to determine the factors leading to poor adherence to obtain successful treatment outcomes. Objective To determine the medication adherence pattern in patients with H. pylori infection and assess the factors associated with non-adherence to the prescribed drug therapy. Method Patients meeting the inclusion criteria who were confirmed as H. pylori positive by rapid urease test (histopathology) and/ or stool antigen test and those under H. pylori eradication therapy were considered. Informed consent was taken from the patients or from the patient party in incapacitated patients. They were then interviewed using structured questionnaire. Statistical analysis was done using SPSS version 20 and a p-value < 0.05 was considered as statistically significant. Result Among the 70 participants included in this study, 57.10% (n=40) of them were males. The mean (±SD) age of the patients was 42.36 years (±17.93). Higher number (85.70% (n=60)) of the patients were adherent to the recommended medication. Forgetfulness was the reason for missing dose in a majority (80% (n=8)) of the nonadherent patients. A highly significant association (p<0.05) was observed between adherence and absence of symptomatic relief. However, there was no statistically significant association (p>0.05) between patients' adherence to gender, age, literacy, and the prescribed treatment regimen. Conclusion Majority of the patients with H. pylori infection were adherent to medication. Forgetfulness was the major reason for missing dose in the non-adherent patients.

Evaluation of Oral Bait Vaccine Efficacy Against Classical Swine Fever in Village Backyard Pig Farms in Bhutan.

Control and eradication of classical swine fever (CSF) in countries with a high proportion of backyard holdings is a challenge. Conventional attenuated Chinese C-strain vaccines, though safe and effective, are difficult to use in backyard farms due to various practical reasons. The aim of this study was to evaluate the efficacy of the CSF oral bait vaccine in village backyard pig farms and to assess the farmers' knowledge on CSF and motivation on using oral vaccines. The pigs were fed the bait by the farmers themselves; one bait was given on day 0, followed by second bait on the next day. Seventy-three per cent (140 of 193 pigs) of vaccinated pigs had either a slight (2-fold-3-fold; 60 pigs) or significant (at least 4-fold; 80 pigs) increase of the antibody titre against CSFV. A significant increase of the antibody titres was mainly observed in pigs with no pre-vaccination titre (OR = 12, 95% CI = 4-40). The number of pigs with protective antibody titres (≥40) rose from 47 (24%) to 115 (60%) following vaccination. Only 30% of the farmers claimed to be familiar with CSF, although clinical signs they mentioned were rather unspecific and could relate to many other pig diseases. Most of the farmers claimed to be motivated to use oral vaccines if made available. The oral vaccine could be a substitute for the conventional attenuated CSF vaccines in areas where it is logistically difficult for veterinarians to visit. It may therefore be a useful tool to combat endemic CSF disease in regions where the disease continues to have a serious impact on the backyard farmers who depend on pig farming for their sustenance and livelihoods.

A Cross-Sectional Study of Medication Adherence Pattern and Factors Affecting the Adherence in Chronic Obstructive Pulmonary Disease.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is considered as a major health problem, associated with mortality and morbidities. Various disease management strategies have been established to optimize patient's longevity and functional status where patient adherence to the prescribed treatment plays a key role. Poor adherence to medication is common among COPD patients and is affected by number of factors like number of medicines, delivery devices and patient-related factors. OBJECTIVE: This study aims to investigate the adherence pattern in the management of COPD and factors affecting patient adherence to the prescribed treatment. METHOD: This study is a cross-sectional study which was conducted in a tertiary care hospital. Those patients suffering from COPD of all age were enrolled in this study and prior informed consent was obtained from patients. The structured questionnaire was used to interview those patients. RESULT: Total 100 patients were enrolled in this study, among which most patients (45%) were of age groups 60-70 years. Unintentional non-adherence to medication attributed for 65% of patients and the major reason was forgetfulness (52.3%). Most patients had discontinued the medication due to experience of side effects (63.3%). The result showed significant association between adherence and polypharmacy (p=0.00). However, there was no significant association between adherence and age, sex, mode of administration of drugs, technics to use delivery devices etc. CONCLUSION: Majority of COPD patients were elderly (mean age= 68.4 years). Forgetfulness was associated with medication non-adherence. Most of the patients had discontinued medication because of side effects. Polypharmacy is one of the major factors associated with non-adherence to medication in COPD.

Correlation between Endoscopic and Histopathological Findings in Gastric Lesions.

Background Stomach is a common site for wide variety of lesions. The visualisation of the site with biopsy leads to the early detection of the pathologic process and appropriate therapy. Objectives The objective of this study is to correlate the histopathological pattern of endoscopic biopsies with distribution of gastric lesions according to age and sex. Method The retrospective study was carried out among 50 cases with endoscopic biopsies and histopathological assessment, received at Department of Pathology, Dhulikhel Hospital- Kathmandu University Hospital. Result Out of 50 cases majority of cases were of male gender with male: female ratio was 1.3:1. Our study showed a poor correlation between endoscopic and histopathological evidence of inflammation in the stomach. Two cases were diagnosed as intestinal metaplasia which were diagnosed as ulcer and erosion endoscopically. Out of 32% of cases diagnosed endoscopically as ulcer, only one case was confirmed histopathologically. Our study showed good correlation in the cases of carcinoma. Out of 17 cases diagnosed endoscopically as gastric carcinoma correlated histopathologically as gastric adenocarcinoma. Majority of carcinoma cases showed ulcerating fungating growth followed by ulcero-proliferative growth. Conclusion Endoscopy is incomplete without biopsy and histopathology is the gold standard for the diagnosis of endoscopically detected lesions. Endoscopic examination and histopathological examination of suspected gastric lesions should go parallel and neither should be a substitute of each other.

Development of 316v antibody enzyme-linked immunosorbent assay for detection of paratuberculosis in sheep.

An enzyme-linked immunosorbent assay (ELISA) was developed and optimised using a Mycobacterium avium subspecies paratuberculosis (MAP) antigen prepared from a C strain (316v) passed through a French press. The optimised assay was evaluated with a panel of sera from MAP infected (n = 66) and uninfected (n = 1,092) sheep. Animals in the MAP infected category were positive on either tissue culture or histopathology but were of unknown serum antibody status. The diagnostic performance and cost of the assay were compared with those of a commercial ELISA (IDEXX). At 99.8% diagnostic specificity the assay showed a diagnostic sensitivity of 23% (95% CI: 15.1-35.8) compared with 36.4% (95% CI: 25.8-48.4) for the commercial ELISA (McNemar's test: chi-square 5.82, p < 0.05). The sensitivities were 5.9% (95% CI: 1-26.9), 27.9% (95% CI: 14.7-45.7) and 35% (95% CI: 18.1-56.7), for low grade, paucibacillary and multibacillary lesion grades, respectively. The cost of the commercial assay kit was 2.7 to 5.2 times greater than that of the 316v ELISA for an equivalent number of tests, the multiple depending on the number of plates processed per run. For flock-level surveillance, to account for the lower sensitivity of the 316v ELISA compared with the commercial ELISA, sample sizes would be increased but the test cost would still be lower. The 316v assay will be useful for diagnosis of Johne's disease in sheep flocks, particularly in developing countries where labour costs are low relative to the cost of consumables.

Endoscopic retrograde cholangiopancreatography at Dhulikhel Hospital: outcome analysis.

BACKGROUND: Endoscopic Retrograde Cholangiopancreatography (ERCP) is an important but potentially invasive therapeutic procedure in treating various pancreatobiliary conditions. In Nepal, the ERCP services is limited to a few tertiary care centers mostly in the capital, Kathmandu. Dhulikhel hospital has started ERCP since 2011 providing services to patients from all over the country. The study analyzes the outcome from data since August 2011 to 2013 August. OBJECTIVE: To analyze the results of ERCP done in Dhulikhel hospital, Kathmandu University hospital. METHOD: This is a retrospective study. The ERCP records of all the patients done since August 2011 to August 2013 were retrieved. A total of 516 attempts of ERCP were done since August 2011 to August 2013. Out of these, 423 were included for the analysis. The repeat ERCP for the same patient due to failed cannulation or patients undergone ERCP but incomplete documentation were excluded. The demographic data, indications, the findings, the outcome in terms of success or failure to cannulation, success or failure of stone extraction, stenting and complications were all derived and analyzed. SPSS 16 version was employed for data management and analysis. RESULT: The female: male ratio was found to be 1.7 : 1. The mean age of patients were 50.57±17.8 Years. The most common indication for ERCP were: choledocholithiasis 208(49.17%); followed by: obstructive jaundice 69(16.3%) of undetermined cause, acute biliary pancreatitis 26(6.4%), suspected bile duct injury during cholecystectomy 18(4.2%), periampullary growth 21( 4.96%), Cholangiocarcinoma 12(2.8%), chronic pancreatitis 10( 2.3%), CBD stent exchange 23(5.43%), dilated cbd 21(4.96%) , acute cholangitis 14(3.3%).The most common finding was CBD stone in 308(72.81%), normal in 51(12.1% ), bile duct stricture in 45(10.63%). Bile duct injury during cholecystectomy was found in 13(3.1%), biliary obstruction due to ampullary growth and pancreatic head mass was found in 21(4.96%) and 6(1.41%) respectively. Choledochal cyst was found in 5(1.2%), chronic pancreatitis in 7(1.7%). Biliary fascioliasis was found in one (0.24%); and roundworm in 1(0.24).The most common complication was acute pancreatitis in 17(4%), post-ERCP cholangitis 6(1.4%), bleeding 6(1.4%), duodenal perforation in 1(0.2%), arrhythmia in 1(0.2%) and one death (0.2%). CONCLUSION: ERCP has been a potentially emerging therapeutic tool for various pancreato-biliary disorders in Nepal.

Safety profile and patient satisfaction of the routine use of propofol in gastrointestinal endoscopy.

BACKGROUD: Routine use of sedation in upper gastrointestinal endoscopy is uncommon in Nepal. There is no study on use of propofol sedation in routine endoscopy examination in Nepal. This study was conducted in order to assess the patient satisfaction and safety profile in patient undergoing routine upper GI endoscopic examination on outpatients. OBJECTIVE: To study safety profile and patient satisfaction of use of propofol in patients undergoing upper GI endoscopy. METHOD: A prospective, observational study was conducted in the endoscopy unit of Dhulikhel hospital, Kathmandu University Hospital from July 2011 to 2012 July. Patients who were referred to upper GI endoscopy were offered to sedation under propofol. Informed consent was taken after explaining side effects, advantages and risk-benefit to the clients. The propofol was administered by the endoscopy nurse under guidance and supervision of the endoscopy performing physician. Data were collected and analyzed using SPSS version 16.0 with 0.05 level of significance. RESULT: Total of 203 patients included in the study. Among 203 patients, 21.2% were males and 78.8% were females; 83.7% were of less than of 60 years age and 16.3% above 60 years of age. The mean total dose of propofol required was 136.08 ± 48.82 mg. Total of 29.1 % of cases required O2 administration during the procedure time due to transient drop in O2 saturation. Total of 4.4% of cases required fluid administration due to transient fall in blood pressure. Total of 68.0% of cases were completely sedated; 28.6% had minor restless and 3.4% showed agitation during induction period of propofol sedation. Total of 99.5% of patients reported pleasant experience while 0.5% reported unpleasant. Among 203 respondents, 98.5% responded they would prefer to do the procedure under propofol sedation in the future; 1.5% responded they did not want sedations in the future. CONCLUSION: Upper GI endoscopy can safely be performed under propofol sedation administered by registered trained nurse under the supervision of endoscopist.

The ratio of aspartate aminotransferase to alanine aminotransferase (AST/ALT): the correlation of value with underlying severity of alcoholic liver disease.

BACKGROUND: Alcoholic liver disease is one of the most frequently diagnosed liver problems in the hospitalized patients in most tertiary care hospitals all over the world .The diagnosis of alcoholic liver disease is most of the time clinical. The AST/ALT ratio is a useful and reliable biochemical marker of liver injury due to alcohol. Whether the value of AST/ALT ratio correlates with clinical severity has not been studied. OBJECTIVES: To study values of AST/ALT ratio in correlation with clinical severity of illness due to alcoholic liver disease using Child-Pugh's grading. METHODS: This is a retrospective study. Inpatient records of all the patients admitted with diagnosis of alcoholic liver disease from July 2009 to 2011 June were analyzed. Data from 174 patients with the diagnosis of alcoholic liver disease-alcoholic hepatitis or alcoholic cirrhosis were retrieved; out of 174 patients, 138 were eligible for the study. The AST/ALT ratio and Child's grading of all the patients were calculated from the documented biochemical and clinical parameters on admission. Demographic profiles of all the patients were also recorded and analyzed. The data was analyzed using software SPPSS 16 version. RESULTS: A total of 138 patients diagnosed as alcoholic liver disease since July 2009 to June 2011 were analyzed. The male-female ratio was found to be 5.34: 1.The mean age of the patients at diagnosis was found to be 47.58 ± 12.83 years. Among 138 patients, Mongolians were found to have the highest prevalence of alcoholic liver disease (38.8%), followed by Newars ( 33.6%), Brahmin and Chhetri (19.1%) and Dalit (7.2%). With respect to AST/ALT ratio and Child's grading of ALD, the mean AST/ALT ratio was found to be 3.03 ± 2.24 in those patients who had Chlild's grade C; likewise the mean AST/ALT ratio was 2.28 ± 1.14, and 1.68 ± 0.83 in patients with Child B and Child A respectively. CONCLUSION: The higher value of AST/ALT ratio is indicative of more severe liver damage due to alcohol.

Role of ultrasound as compared with ERCP in patient with obstructive jaundice.

BACKGROUND: The diagnosis of obstructive jaundice relies on proper history taking, clinical examination, laboratory investigations and different non invasive imaging modalities like Ultrasonography (USG), Cholangio Computed Tomography (CCT), Magnetic resonance Imaging (MRI) with Magnetic Resonance Cholangio Pancreatography (MRCP) and invasive modalities like endoscopic retrograde cholangiography (ERCP) and percutaneous trans hepatic cholangiography (PTC). OBJECTIVE: To compare the role of ultrasound with endoscopic retrograde cholangiography and to determine the major causes of obstructive jaundice in our prospect. METHODS: This was a prospective, analytical study conducted on 88 patients presenting to Department of Radiodiagnosis and Imaging at Dhulikhel Hospital-Kathmandu University hospital from March 2011 to August 2012 with clinical diagnosis of obstructive jaundice. Sonographic evaluation was performed in Siemens acusion x-150 and x-300. The final diagnosis was made by endoscopic retrograde cholangiography and /or surgery and confirmed histopathologically. RESULTS: The most common benign causes of obstructive jaundice were choledocholithiasis (63%), CBD stricture (12.3%), cholangitis (8%) and pancreatitis (6.85%) whereas cholangio carcinoma (6.85%) and carcinoma head of pancreas (4%) comprised of the malignant causes . Ultrasonography had sensitivity of 100% and specificity of 89% in detecting choledocholithiasis. It was found to be 98.78% sensitive and 83.33% specific in cholangiocarcinoma. Similarly in pancreatitis, the sensitivity of ultrasonography was 97.59% and sensitivity was 66.67%. CONCLUSION: Ultrasonography acts as a valuable diagnostic imaging modality in detecting the causes of obstructive jaundice. Due to its easy availability, non invasive nature and cost effectiveness, it can be considered as the first line imaging technique/ tool. ERCP is the invasive imaging tool and can be used for both diagnostic and therapeutic purpose.

The predictive value of pre-operative symptoms including upper gastrointestinal endoscopy before laparoscopic cholecystectomy for elective symptomatic cholecystolithiasis.

BACKGROUND: It has always been a challenge to distinguish between upper gastrointestinal symptoms due to gall stones or any other causes. The persistence of abdominal symptoms even after cholecystectomy is highly discouraging for surgeons. OBJECTIVE: To evaluate the value of preoperative (UGE) as a routine investigative tool in patients with gall stone disease and to assess the outcome of cholecystectomy in patients with gallstones on preoperative abdominal symptoms. METHODS: This is a prospective study conducted on 96 cases at the Department of Surgery, Dhulikhel Hospital among ultrasonographically proven gall bladder stones irrespective of age and sex. After the examination, all the patients were subjected to UGE, and biopsy were obtained for histopathology if required. The statistical analysis were performed using spss version 16. RESULTS: Out of total patients, 84(87.5%) were females and 12(12.5%) were males with a M: F ratio of 1:7. Both the sexes were comparable in age groups. Out of total 96 patients, 53(55.2%) presented with typical pain and 43(44.8%) presented with atypical pain. All the patients were subjected to upper gastrointestinal endoscopy (UGE) and 53(55.2%) had normal findings and 43(44.8%) had various lesions. Patients with typical pattern of pain had normal endoscopic findings and those with atypical pain had pathology in upper gastroendoscopy (p<0.001). Serious pathology resulting to change of the planned treatment was found in three cases (3.12%). Among them two had gastric carcinoma and one had active peptic ulcer disease. The relief rate after the cholecystectomy was significant in patients with typical pain than among those with atypical pain (p<0.001). The commenest post cholecystectomy symptoms were heart burn (10%), abdominal discomfort (9%) and dyspepsia (7%). CONCLUSION: Presence of atypical pain in patients with gall stones is highly likely to have other coexisting upper gastrointestinal pathologies. Hence, upper gastrointestinal endoscopy prior to elective cholecystectomy in patients with gall stones can be clinically helpful.

Upper gastro-intestinal bleeding: aetiology and demographic profile based on endoscopic examination at Dhulikhel Hospital, Kathmandu University Hospital.

BACKGROUND: The upper gastrointestinal bleeding (UGIB) is defined as bleeding within the intraluminal gastrointestinal tract from any location between the upper oesophagus to the duodenum at the ligament of Treitz. It is one of the important medical emergencies worldwide. OBJECTIVE: The objective of this study is to study the aetiology of upper gastrointestinal bleeding based on endoscopic examination findings in patients of various demographic characteristics. MATERIALS AND METHODS: This is a retrospective observational study. The endoscopic record book from 2007 January to 2009 October was reviewed for all the cases who underwent oesophago-gastro-duodenoscopic examination for upper GI bleeding. The clinico-epidemiological data of all the patients was reviewed and analyzed in concert with the aetiology of bleeding. RESULTS: A total of 90 patients (58 males, 32 females; mean age 45.32+ 18.47 years) of upper gastrointestinal bleeding was studied and analyzed in terms of aetiology of bleeding and demographic profile. Among the ethnic groups, Aryan 46 (51%) was the most common ethnic group to have upper GI bleeding followed by Newars 24 (27%), Mongolians 16 (18%), Dalits 3 (3%) and others 1 (1%). Out of 90 patients, 47( 52.2%) cases was less than 45 years of age, 30(33.3%) of 46 to 65 age ; and 13(14.4 %) more than 65 years of age. Gastric ulcer 23(25.6%) was the most common endoscopic finding, followed by oesophageal varices 14 (15.6%), acute erosive/haemorrhagic gastropathy 11 (12.2%), duodenal ulcer 9(10%), growth 7(7.8%), vascular lesions 3(3.3%), Mallory-Weiss tear 1(1.1%), fundal varices 1(1.1%) and, no cause was identified in 21(23.3%) cases. The peptic ulcer bleeding was the most common finding in Aryan 22(47.9%), whereas oesophageal varices and growth were more common in Newar 7(29.2%) and 3 (12.5%) respectively. CONCLUSION: Peptic ulcer disease is the most common cause of upper GI bleeding which was most commonly found in Aryan population; followed by oesophageal varices and growth as second and third most common causes and were more prevalent in Newar and Mongolian people.

Distribution and prevalence of footrot in Bhutan.

The first cases of footrot in Bhutan were reported in sheep in 1990 at the National Sheep Breeding Centre (NSBC), which supplies breeding animals to village sheep flocks throughout Bhutan. Despite the presence of footrot at the Centre the distribution of apparently disease-free sheep continued. Cases of footrot were reported in village flocks soon after the disease was diagnosed at NSBC. A national survey was designed to establish the distribution and prevalence of footrot in Bhutan. This detected footrot in 19/94 village sheep flocks surveyed. The 19 affected flocks were distributed among nine different administrative districts whereas the villages selected were in 13 of a total of 16 sheep growing districts. The highest within-flock prevalences were among the seven flocks sampled in Bumthang district (mean 20.4%). The prevalence of the disease within flocks was generally much lower in other affected districts and in three districts a single affected animal was identified in the sample of 14 sheep examined in each village. Nationally, footrot prevalence was estimated to be 3.1% (95% CI 2.16-4.04%). There was a positive association between the receipt of animals from NSBC and the presence of footrot. The prevalence of the disease was higher in flocks with a migratory system of management than in those using a sedentary system. The relative risk of there being footrot in a migratory flock was nine-times higher than in a non-migratory flock. Only one strain of Dichelobacter nodosus (serogroup B) was identified among the 234 isolates obtained from the 19 affected flocks. Sheep with footrot healed quickly when treated with a vaccine made from this strain.
