Comparative Study between the Use of Pigtail Catheters and Traditional Chest Tube Drain in Cases with Pneumothorax.

Background Pneumothorax is a condition in which air or other gas is present in the pleural cavity. Mainstay of management of pneumothorax is to remove the air from the pleural space usually done by chest tube insertion. There is still uncertainty whether minimal invasive management with pigtail catheter is sufficient for the management of pneumothorax. Objective To find the effectiveness, safety, tolerability, efficacy of pigtail catheters and large bore chest tubes. Method Prospective comparative study was done in Dhulikhel Hospital between August 2019 till August 2021. Chest tube insertion used to be the only available treatment modality till December 2020 (15 months). Following January 2021 after obtaining ethical clearance for use of pigtail insertion for pneumothorax, this treatment modality was done (8 months). Result Among 76 patients, 52(68.4%) underwent a large bore chest tube and 24 (34.6%) pigtail catheter patients. Mean age of the patients was 48 years (SD 18.01). Duration of hospital stay and length of hospital stay was more in large bore catheters and less in pigtail catheters. Eight hours post tube placement of the expansion of the lungs was present in pigtail and was statistically significant. Pain killer used in pigtail catheters was limited to Non-steroidal anti-inflammatory drugs, for large bore catheter opioids were added and were statistically significant. Conclusion Pigtail catheter is nearly effective as compared to traditional wide bore catheters.

Meniscal Tear at Knee: Repair or Resect? An Early Experience from a University Hospital in Nepal.

Background The meniscus plays an important role in maintaining healthy articular cartilage. Meniscus tear, one of the common intra-articular knee lesions, is treated by either debridement or repair. Objective This study aims at identifying the early outcome of meniscus tears treated by debridement or repair. This study also elaborates on the spectrum of meniscal injuries presented in a tertiary care hospital in Nepal. Method A retrospective descriptive cross-sectional study was conducted at Orthopedic Department of Dhulikhel Hospital from February 2018 until January 2020 among patients who underwent knee arthroscopies for meniscal tears treated either by debridement or repair. Patients having intra articular fractures, osteochondral injuries and multi-ligament injuries were excluded. The meniscal tears were classified according to location and type of tear. Those patients who had at least one-year of follow up were evaluated with Lysholm score for functional outcome. Data were compiled and analyzed with Microsoft Excel 2011. Result One hundred and ten cases of meniscal tears were managed over the study period. Ninty-three cases could be traced for outcome evaluation, which included 50 cases of meniscal debridement and 43 cases of meniscal repair. The mean Lysholm score of the patients who received debridement was 81.5 (SD 10.4) and those who received meniscal repair was 84.9 (SD 9.1) (p=0.105). The population distribution was found to be similar in both the groups according to age and sex distribution and associated ligamentous injuries. Conclusion Good functional outcome was seen for meniscal tears managed with debridement or repair in at least one year follow up and could not establish one modality of management better than the other.

Radiographic Study of Distal Radius Parameters in Patients Visiting Tertiary Care Hospital.

Background The important morphological parameters of distal radius namely palmar tilt, radial inclination, radial height and ulnar variance are consequential in the evaluation and management of the distal radius fracture, distal radius plate design and kinesiology. Correction of these parameters in anatomical alignment is important to restore the normal biomechanics of the wrist joint. Objective To ascertain the distal radius parameters in the patients attending tertiary care hospital with regard to gender and age. Method The wrist radiographs (postero-anterior and lateral views) of 125 patients, from 16 to above 60 years of age were used to determine the four parameters of distal radius. The subjects were divided into gender and three different age groups (16-36 years, 37-57 years and > 57 years). Independent t-test and ANOVA test was used for statistical analysis with level of significance set at p ≤ 0.05. Result The mean palmar tilt was 15.69 ± 4.84° (p-value = 0.40). The mean radial inclination was 22.58 ± 2.82° (p-value = 0.88). The mean value of radial height was 10.31 ± 1.59 mm (p-value= 0.001). Positive ulnar variance were recorded in maximum of subjects (46.40%) and the least was neutral (16.80%). Conclusion The distal radius parameters of our population were similar to the Orthopedic Trauma Association standard reference value. And there was significant difference in radial height between males and females.

First-Generation SARS-CoV-2 Vaccines: A Comparative Analysis between Vaccinated and Unvaccinated Hospitalized Patients Infected with SARS-CoV-2.

Background Severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) variants, which have emerged due to several mutations in spike protein, have a potential to escape immune protection provided by the first-generation vaccines, thereby resulting in breakthrough infections. Objective To identify the socio-demographic factors, clinical features, and outcomes in both vaccinated and unvaccinated hospitalized patients infected with SARS-CoV-2. Method Socio-demographic details, clinical features, and the outcomes among fully vaccinated (double for Covishield/AstraZeneca and BBIBP-CorV and single for Janssen), partially vaccinated, and unvaccinated hospitalized patients with coronavirus disease of 2019 (COVID-19) were collected and analyzed using SPSS version 17. Result Among the hospitalized COVID-19 patients (n=299), 175 (58.5%) patients received a single-dose, 82 (27.4%) double-dose, and 124 (41.5%) did not receive any dose of the COVID-19 vaccines. The risk of SARS-CoV-2 infection when compared between vaccinated and unvaccinated patients was found to be associated among professional degree holders (23.4% versus 9.7%) (p<0.05), professional workers (43.4% vs. 25.0%) (p<0.05), hospitalization to general ward (76.6% vs. 72.6%) (p<0.05), and presence of multiple symptoms (> or equel 3) (86.8% vs. 75.0%) (p>0.05) and comorbidities (> or equal 2) (15.5% vs. 13.7%) (p>0.05). Despite such approximate incidences, the risk of in-hospital mortality among the vaccinated patients was reduced (0.6% vs. 3.2%) (p>0.05), when compared to the unvaccinated patients. The risk of in-hospital mortality was associated with the older age and the presence of multiple comorbidities including bronchial asthma, diabetes, and hypertension. Conclusion Full or partial vaccination against the SARS-CoV-2 variants of concerns might be effective in preventing in-hospital mortality among COVID-19 patients.

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.

Comparative Efficacy and Safety of Diacerein in Patients with Knee Osteoarthritis: A Pilot Study.

Background Osteoarthritis (OA) is the most common chronic rheumatic disease. The prevalence of OA is skyrocketing with time. Providing a proper treatment regimen for OA is also growing as a major public health challenge. Conventional pharmacological treatments are mainly for alleviating pain and have some severe adverse effects. Diacerein is a new oral anti-inflammatory drug especially developed for the management of OA having only mild to moderate adverse effects. However, the evidence of efficacy and safety of Diacerein in OA is not well documented and yet to be explored. Objective To compare the efficacy and safety of Diacerein in knee OA with conventional nonsteroidal anti-inflammatory drugs (NSAIDs). Method A comparative study was conducted among knee OA patients attending OutPatient Orthopedic department in Dhulikhel Hospital, Nepal from December 2019 to September 2020, using self-structured and standard questionnaire. The patients were randomized to receive either a conventional standard treatment (Treatment Group I: NSAIDs) or alternative treatment regimen (Treatment Group II: NSAIDS+ Diacerein). Patients were followed-up after two months and data were analyzed using SPSS 21.0. Result Among 72 patients enrolled in this study, majority (44.44%) were between 51-60 years of age in which 81.94% of the patients were female. Post treatment data was collected from 15 participants. The mean KOOS-PS score of the participants in Treatment Group I decreased from 35.56 ± 14.33 to 35.14 ± 12.65 while that of the Treatment Group II participants reduced from 63.31 ± 12.08 to 49.99 ± 13.10 in two months. Similarly, the mean WOMAC score decreased from 46.87 ± 17.80 to 34.37 ± 16.83 in Treatment Group I and from 54.23 ± 14.66 to 46.22 ± 12.16 in Treatment Group II. The mean Lysholm score in Treatment Group I increased from 55.57 ± 8.16 to 60.86 ± 15.01 and in Treatment Group II, it increased from 46.62 ± 13.01 to 60.25 ± 17.598. Conclusion Diacerein treatment group had better functional outcome compared to the patients in the treatment group with conventionally used drugs. Also, the adverse effects faced by the patients were minor. The current study are suggestive of better efficacy and safety of Diacerein compared to other drugs.

Behcet's Disease with Absent HLA Serotyping and Pathergy Test.

Behcet's disease is a multisystemic vasculitis of unknown etiopathogenesis characterized by recurrent acute inflammation. A 30-year male presented with progressive blurred vision in both eye for one month associated with photophobia, redness and ocular pain. On presentation best corrected visual acuity was 6/9 both eyes. Bilateral ocular examination of anterior segment demonstrated occasional cells. Treatment history of multiple joint pain along with oral aphthous ulcers. Erythematous papulopustular lesion over face, neck, trunk and genital ulcers were being treated. Irrespective of negative human leucocyte antigen B51 and pathergy, patient was diagnosed as Behcet's disease on the basis of clinical criteria and started with topical steroid and cycloplegic. At one-month, ocular symptoms were relieved. Behcet's disease is a rare, autoimmune disease, which lacks universal pathognomonic test and investigations, therefore diagnosis is primarily done with international criteria for Behcet's disease. Multidisciplinary approach certainly helps in early diagnosis and eliminating morbidity.

The Study of Burden of Family Caregivers of Patients Living with Psychiatric Disorders in Remote Area of Nepal.

Background Family caregivers of psychiatric disorders likely to face burden. There is a paucity of data regarding the caregiver burden in psychiatric disorders in context of Nepal. Objective To study the caregiver burden in families with psychiatric illness and to find association between socio-demographic variables and caregiver burden in families with psychiatric illness. Method This is an analytical cross-sectional study. The participants (n=96) were caregiver of patients visiting outpatient department of two government of Nepal primary health care centers namely, Panchkhal Primary Health Care Center (PHC) Kavre District and Barhabise Health Care Center Sindhupalchowk district. The sample size has been determined by using statistical formula. Family burden assessment schedule (FBIS) was used for the study. Result The majority of the caregivers were females 56.3%. Most of the caregivers were aged below 45 years 54.2%. The large number of participants were single or separated 74%. The mean score of family burden assessment schedule was 27 ± 9.8 (range 0 to 48) with positive rate of 59.4%.Among the objective burden domains disruption of family leisure 61.5% was the most frequently reported burden. The subjective burden was reported in 95%. There were significant differential demographic associations with different domains of caregivers' burden. Conclusion Caregivers of Psychiatric patients experience different kind of burden of care. Our findings highlight the support to the family members to reduce their burden.

Anxiety and Depression during COVID-19 Pandemic among Medical Students in Nepal.

Background Medical students' psychological response to societal lockdown during the COVID-19 pandemic has not been studied much. Objective To assess levels of anxiety and depression among medical students during initial stages of COVID-19 pandemic in Nepal and relate their distress to relevant variables. Method A cross-sectional study with online questionnaire was conducted among medical students at different colleges in Nepal. Hospital Anxiety and Depression Scale (HADS) detected 'anxiety' and 'depression'. The covariates were explored by logistic regression analyses. Result A total 416 medical students [mean age: 22.2 (2.1); males 57.7%, females 42.3%] participated. HADS-anxiety scores [mean: 7.1(4.3)] were significantly and positively correlated with HADS-depression [mean: 5.9 (4.1)] (r=0.695; p < 0.001). Point prevalence of total HADS caseness (HADS-T) was 26.7%. Specific HADS-defined caseness were: anxiety (HADS-A) 11.8%, depression (HADS-D) 5.5%, and comorbid anxiety and depression (HADS-cAD) 9.4%. All four types of caseness were significantly more prevalent among students with a history of mental problems (AOR=4.7, 3.2, 2.6, and 3.2 respectively). HADS-T was higher among those with a concurrent physical illness (AOR=2.4). HADS-T, HADS-A and HADS-D scores were higher among the age group > 22 years (AOR= 2.2, 2.5 and 4.4 respectively). HADS-cAD was almost threetimes higher among those with a possible COVID-19 exposure (AOR=2.8). Conclusion A significant number of medical students in Nepal suffered from high levels of anxiety and depression during the COVID-19 shut-down. The students in the higher (> 22 years) age group, those with past mental disorders, possible COVID-19 exposure, and concurrent physical illness showed elevated levels of anxiety and/or depression.

Multi-drug Resistant and Extended Spectrum ß-lactamase Producing Salmonella Species Isolated from Fresh Chicken Liver Samples.

Background Emergence of antibiotic resistance among microbes contaminating the fresh meat products is a global public health concern as they can be easily transmitted to humans through their consumption and contact. Objective The current study was conducted to determine the distribution of antimicrobial resistance among Salmonella species isolated from fresh chicken liver samples with special emphasis on extended spectrum beta-lactamase (ESBL) production. Method A total of 200 fresh chicken liver samples were cultivated for the isolation of Salmonella and further subcultivated to detect extended spectrum beta-lactamase production among them. Antimicrobial susceptibility testing (AST) was done by disk diffusion method using a panel of 7 antimicrobials. Result Out of 200 samples analyzed, 61 (30.5%) samples harbored Salmonella species out of which 15 (7.5%) samples showed the presence of Salmonella Typhi. A significant association was noted in the incidence of Salmonella with various factors pertaining to the butchers, such as age, sex, literacy rate, practices of washing knives and chopping board, wearing aprons and gloves and type of water used (p < 0.05). Salmonella isolates were highly sensitive to amikacin (82.0%) and least sensitive to tetracycline (3.3%). All the isolates were resistant to colistin. Sixty (98.4%) isolates were identified as multi-drug resistant (MDR). The total number of extended spectrum betalactamase producers reported among Salmonella isolates was 29 (47.5%). Conclusion The results indicate that the fresh chicken liver samples sold in Bharatpur Metropolis are reservoirs of multi-drug resistant Salmonella, including extended spectrum betalactamase producers, that could potentially be transmitted to the humans by direct contact or through inadequate cooking.

Depression, Alcohol Use, Antiretroviral Therapy Adherence and HIV Status among HIV-infected from Multiple Antiretroviral Therapy Clinics in Nepal.

Background Depression and alcohol use disorder are very common among people living with HIV infection, these disorders are not only common among HIV patients but also associated with antiretroviral therapy (ART) non adherence, morbidity and mortality. Objective The objective of our study is to study the prevalence of Depression, Alcohol use, and ART treatment adherence. Method This is a analytical cross-sectional study. Total of 221 participants were included in the study. Convenient method of sampling was used to collect the data from three district Kathmandu, Lalitpur and Kavre ART (Antiretroviral treatment) clinics. Beck Depression Inventory (BDI) was used for the assessment of depression, Alcohol use disorders identification test (AUDIT) was used for alcohol related problems and Visual analogue scale (VAS) was used for treatment adherence. Chi square test and multiple linear regression analysis were conducted for testing bivariate and multivariate relationship of sociodemographic and clinical factors with depression and treatment adherence. Result The 40% participants found to have depression. Variables associated with depression significantly after multiple regression analysis were employment (p value=0.04) and mode of transmission (p value= 0.003). More than half, 56% of the participant's CD4+ cells count was < 500 per cubic millimetre and 71% participant's viral load was undetectable. Clinical variables mode of transmission (pvalue=0.000), duration of illness (p value=0.03) and duration of treatment (p value=0.01) were significantly associated with depression. ART treatment adherence was significantly associated with CD4 cell (p value=0.02) and viral load (p value= 0.05). Conclusion Depression is very prominent among HIV positive patients. Low CD4+ cell count and high viral load has been seen among patients who are not adherent to antiretroviral treatment. It is suggested that clinicians should carefully assess the possibility of depressive symptoms in their patients on ART treatment.

Improving Knowledge, Skill and Confidence of Novice Medical Doctors in Trauma Management with Principles of ABCDE.

Background Trauma is one of the major public health concerns clamming about five million death annually worldwide. Experience and confidence of a doctor in the management of trauma patients have big impact on the overall outcome. Objective This study aims to evaluate the outcome of a trauma course in improving the knowledge, skill and confidence of novice doctors in managing trauma victims. Method A pre/post test analytical study was carried out among novice medical doctors from Kathmandu University School of Medical Science (KUSMS) who participated in a standard two and a half day trauma course, that utilizes the principles of ABCDE, as a part of their regular training. Pre-course knowledge and skill were compared with immediate post-course scores on the same guidelines. Objective structured and subjective written feedbacks from the participants were analyzed qualitatively to identify the perceptions of candidates. Result Sixty-eight males and twenty-nine females completed the course. The average pre-test scores in knowledge and skill were 8.3(33.2%) and 19.6(78.5%) respectively. Similarly the post-test scores were 16.04(64.2%) and 22.45 (89.5%) respectively, showing statistically significant improvements (P 0.000). The mean percentage improvement in knowledge was 48.8% and that in skill was 160.9%. The feedback analysis showed majority of the participants were satisfied with the course and they perceived improved "self-confident" in handling trauma cases. Conclusion All the novice doctors should participate in a standard trauma course hence their knowledge, skill and confidence in handling a trauma can be improved.

Clinical Outcome following Intra-articular Triamcinolone Injection in Osteoarthritic Knee at the Community: A Randomized Double Blind Placebo Controlled Trial.

Background Knee pain is one of the common complaints patients present with in any community based health camps and Osteoarthritis of knee is a usual diagnosis. Injecting a long acting steroid is a common practice to alleviate the symptoms of osteoarthritic knee. Objective To evaluate the clinical outcome of injecting Triamcinolone acetenoid in osteoarthritis of knee in a community set up over a randomized double-blind placebo control trial. Method A prospective, randomized, double blind, placebo control trial was carried out in community after obtaining the ethical clearance from the IRC. Patients with clinically diagnosed osteoarthritis of knee were injected either Triamcinolone or Placebo after recording the baseline scores of the knee by Knee injury and Osteoarthritis Outcome Score (KOOS) - Physical Function Short form (KOOS-PS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Visual Analogue Scale (VAS). The same tools were used at two, six and at twelve weeks post injection to evaluate the functional outcome and pain. Result One hundred and seventeen patients were available for analysis among which, 55(48.7%) patients received Triamcinolone and 58(51.3%) received placebo. The baseline status of knees of two groups was comparable at the start of study. There was significant pain relief in the group receiving Triamcinolone at two and six week but not in twelve weeks. Group receiving placebo had pain relief only for first two weeks. Functional outcome was significantly improved compared to baseline in both the groups until six weeks however, in the triamcinolone group, it was significant until twelve weeks. No major complications were noted. Conclusion Intra-articular injection of Triamcinolone acetenoid is effective in symptoms control and improving functional outcome in clinically diagnosed osteoarthritis of knees in community set up during health camps.

Suicide in Nepal: a modified psychological autopsy investigation from randomly selected police cases between 2013 and 2015.

PURPOSE: Yearly, 600,000 people complete suicide in low- and middle-income countries, accounting for 75% of the world's burden of suicide mortality. The highest regional rates are in South and East Asia. Nepal has one of the highest suicide rates in the world; however, few investigations exploring patterns surrounding both male and female suicides exist. This study used psychological autopsies to identify common factors, precipitating events, and warning signs in a diverse sample. METHODS: Randomly sampled from 302 police case reports over 24 months, psychological autopsies were conducted for 39 completed suicide cases in one urban and one rural region of Nepal. RESULTS: In the total police sample (n = 302), 57.0% of deaths were male. Over 40% of deaths were 25 years or younger, including 65% of rural and 50.8% of female suicide deaths. We estimate the crude urban and rural suicide rates to be 16.1 and 22.8 per 100,000, respectively. Within our psychological autopsy sample, 38.5% met criteria for depression and only 23.1% informants believed that the deceased had thoughts of self-harm or suicide before death. Important warning signs include recent geographic migration, alcohol abuse, and family history of suicide. CONCLUSIONS: Suicide prevention strategies in Nepal should account for the lack of awareness about suicide risk among family members and early age of suicide completion, especially in rural and female populations. Given the low rates of ideation disclosure to friends and family, educating the general public about other signs of suicide may help prevention efforts in Nepal.

Synchronization dynamics on the picosecond time scale in coupled Josephson junction neurons.

Conventional digital computation is rapidly approaching physical limits for speed and energy dissipation. Here we fabricate and test a simple neuromorphic circuit that models neuronal somas, axons, and synapses with superconducting Josephson junctions. The circuit models two mutually coupled excitatory neurons. In some regions of parameter space the neurons are desynchronized. In others, the Josephson neurons synchronize in one of two states, in-phase or antiphase. An experimental alteration of the delay and strength of the connecting synapses can toggle the system back and forth in a phase-flip bifurcation. Firing synchronization states are calculated >70 000 times faster than conventional digital approaches. With their speed and low energy dissipation (10^{-17}J/spike), this set of proof-of-concept experiments establishes Josephson junction neurons as a viable approach for improvements in neuronal computation as well as applications in neuromorphic computing.

Prevalence of Gall Stones in Liver Cirrhosis.

INTRODUCTION: Increased incidence and prevalence of gallstones in liver cirrhosis has already been reported by many studies. This study aimed to investigate the prevalence of gallstone disease in Nepali patients with LC and to identify risk factors for gallstone formation. METHOD: Consecutive patients of LC presenting to liver clinic from January, 2010 to December, 2012 were evaluated for GS by ultrasonography at their first visit. Liver cirrhosis was diagnosed on the basis of clinical features, laboratory parameters, ultrasonography, and/or histopathology. RESULT: Two hundred and twenty four LC patients were studied. Male to female ratio was 2.3:1. Alcohol was the major etiological factor for LC followed by hepatitis B, alone or in conjunction with alcohol. Seventy-four patients (33%) were found to have GS. Incidence of GS was more in advance stage of cirrhosis. There was no significant correlation between formation of GS and etiology of LC, except for the HCV related liver cirrhosis, in which it was present in 39% of the patients. More the advance disease,more was the incidence as 57% of Child-C patients had GS. Portal vein diameter was also associated with GS formation. When portal vein diameter was more than 13 mm, there was more GS formation. CONCLUSIONS: One third of the patients of LC showed GS at the presentation. Patients with HCV related cirrhosis are more prone to develop GS than other. Severity of the disease and portal vein diameter was found to be associated with GS formation.

Genetic association of impulsivity in young adults: a multivariate study.

Impulsivity is a heritable, multifaceted construct with clinically relevant links to multiple psychopathologies. We assessed impulsivity in young adult (N~2100) participants in a longitudinal study, using self-report questionnaires and computer-based behavioral tasks. Analysis was restricted to the subset (N=426) who underwent genotyping. Multivariate association between impulsivity measures and single-nucleotide polymorphism data was implemented using parallel independent component analysis (Para-ICA). Pathways associated with multiple genes in components that correlated significantly with impulsivity phenotypes were then identified using a pathway enrichment analysis. Para-ICA revealed two significantly correlated genotype-phenotype component pairs. One impulsivity component included the reward responsiveness subscale and behavioral inhibition scale of the Behavioral-Inhibition System/Behavioral-Activation System scale, and the second impulsivity component included the non-planning subscale of the Barratt Impulsiveness Scale and the Experiential Discounting Task. Pathway analysis identified processes related to neurogenesis, nervous system signal generation/amplification, neurotransmission and immune response. We identified various genes and gene regulatory pathways associated with empirically derived impulsivity components. Our study suggests that gene networks implicated previously in brain development, neurotransmission and immune response are related to impulsive tendencies and behaviors.

Acute pancreatitis in acute viral hepatitis.

INTRODUCTION: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. METHODS: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. RESULTS: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. CONCLUSIONS: Acute pancreatitis occurred in 6.5% of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management.
