Molecular and Entomological Characterization of 2023 Dengue Outbreak in Dhading District, Central Nepal. Viruses 2024; 16:594. [PMID: 38675935 PMCID: PMC11053854 DOI: 10.3390/v16040594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/07/2024] [Accepted: 04/09/2024] [Indexed: 04/28/2024] Open
Abstract
In 2023, Nepal faced its second largest dengue outbreak ever, following a record-breaking number of dengue cases in 2022, characterized by the expansion of infections into areas of higher altitudes. However, the characteristics of the 2023 circulating dengue virus (DENV) and the vector density remain poorly understood. Therefore, we performed DENV serotyping, clinical and laboratory assessment, and entomological analysis of the 2023 outbreak in central Nepal. A total of 396 fever cases in Dhading hospital suspected of being DENV positive were enrolled, and blood samples were collected and tested by different techniques including PCR. Of these, 278 (70.2%) had confirmed DENV infection. Multiple serotypes (DENV-1, -2, and -3) were detected. DENV-2 (97.5%) re-emerged after six years in Dhading while DENV-3 was identified for the first time. Dengue inpatients had significantly higher frequency of anorexia, myalgia, rash, diarrhea, nausea, vomiting, abdominal pain, and thrombocytopenia (p < 0.05). In this area, Aedes mosquitoes largely predominated (90.7%) with the majority being A. aegypti (60.7%). We also found high levels of Aedes index (20.0%) and container index (16.7%). We confirmed multiple DENV serotype circulation with serotype re-emergence and new serotype introduction, and high vector density in 2023. These findings call for the urgent initiation and scaling up of DENV molecular surveillance in human and mosquito populations for dengue control and prevention in Nepal.

Abstract
Background Mucoid degeneration of anterior cruciate ligament is characterized by infiltration of mucoid-like material scattered throughout the anterior cruciate ligament substance. It is an uncommon condition, but previously, underdiagnosed or often misdiagnosed as an anterior cruciate ligament tear. Objective To present our early experiences with mucoid degeneration of anterior cruciate ligament in last five years in terms of clinical presentation and the outcomes of arthroscopic management. Method This was a retrospective descriptive cross-sectional study on patient who received arthroscopic debridement for mucoid degeneration of anterior cruciate ligament in Dhulikhel Hospital over five years period (2017 May to 2022 April). Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale that has been translated and validated to be used in local (Nepali) language and context was used for evaluation of outcome evaluation. Result Twenty-one patients of mean age 44.21 years, predominantly females (18), were managed in five years period. The mean Western Ontario and McMaster Universities Osteoarthritis Index score was 16.33±10.47 with a range of 0 to 36 (11.57 to 21.09 at 95% confidence interval). The mean Western Ontario and McMaster Universities Osteoarthritis Index score converted on a scale of 0 to 100 was 17. Thirteen patients had isolated Mucoid degeneration of anterior cruciate ligament whereas nine others had associated either meniscal tear or chondral lesions. Conclusion Mucoid degeneration of anterior cruciate ligament could be a cause of knee pain in middle-aged patients and arthroscopic debridement can improve the patient's symptoms and provide a good functional outcome.

Abstract
Introduction: Cholesterol has been blamed as the principal cause of cardiovascular diseases, however, it is a common observation that most coronary artery disease patients do not have strikingly high cholesterol values, often falling within the desirable range, and also many patients with high cholesterol levels do not have any atherosclerotic cardiovascular diseases. Therefore, we decided to investigate whether there is an association between cholesterol levels and coronary artery disease.
Materials and Methods: This is a case-control study conducted on a total of 313 coronary heart disease patients and 369 controls diagnosed by coronary angiogram. Fasting lipid profile was analyzed for both cases and controls. The study extended for a period of three years from 2018 July to 2020 June.
Results: Total cholesterol (p<0.05) and Low-Density Lipoprotein (p<0.05) levels were significantly lower among the cases, while triglyceride and High-Density Lipoprotein levels of cases were similar to the controls.
Taking age into consideration, there was no significant difference in the total cholesterol and Low-Density Lipoprotein levels between cases and controls below the age of 60 years, however, above the age of 60 years, total cholesterol and Low-Density Lipoprotein were significantly lower in the cases (p<0.05).
Conclusions: The findings of the present study indicated that either there was no association between cholesterol levels and coronary artery disease or an inverse association when age was taken into consideration, as above 60 years of age the cholesterol level was found to be significantly lower in the patients of coronary artery disease compared to controls.

Abstract
Background The nationwide lockdown was imposed upon by the Government of Nepal with regards to the COVID-19 pandemic. Even during times of limited mobility and travel, trauma cases were presenting to the hospital. Objective To asses trauma patterns among patients presented to the Emergency department in Dhulikhel hospital during the lockdown period. The assessment of the burden of trauma during the pandemic could aid in planning allocation of resources and improving trauma care. Method A retrospective cross-sectional study design was used to assess all patients with a history of trauma during the period of lockdown announced by the Government of Nepal for COVID-19 from March 24 to June 14, 2020. Result Among 2097 patients that visited the emergency department, 23% were trauma cases. In comparison to the corresponding time-period in 2019, trauma cases reduced by more than half (54.5%). The majority of patients utilized ambulances as a means of transportation; a few patients utilized Dhulikhel emergency medical services. The most common mechanism of injury was fall injury, followed by motor vehicle accident and physical assault. Traumatic brain injury occurred in 30% of patients. Of all patients, 71% were discharged after initial treatment, 26% were admitted to different wards and 3% were referred to other health centres. Conclusion Fall injury is a crucial public health concern followed by motor vehicle accident among trauma patients even during the pandemic condition. Thus, emergency rooms should aid in planning for preparedness, mitigation of trauma during situations like these, in planning the allocation of resources and improving trauma care.

Abstract
Background COVID-19 is significantly affecting the healthcare system globally. As a result, healthcare workers need to be updated on the best practices for the proper management of the disease. Objective The purpose of this study was to assess the knowledge, attitude, and practices (KAP) related to COVID-19 among healthcare personnel. Method This was a cross-sectional study conducted among medical personnel at Dhulikhel Hospital Kathmandu University Hospital using a semi-structured questionnaire on KAP related to COVID-19 from May 8th to June 8th, 2020. We analyzed survey data by using descriptive statistics. Spearman rank correlation, chi-square test and binary logistic analysis were used to examine the association between sociodemographic characteristics with KAP related to COVID-19. Result Among 220 participants, the majority were nurses (60%) followed by doctors (27.7%), paramedics (10%) and technicians (2.3%). The results showed that 68.6% of healthcare personnel had a good knowledge with appropriate practices (98.5%) and negative attitude (59.3%). In the multivariate binary logistic analysis, the healthcare workers with the clinical experience level of one to five years (OR:.42, 95% CI:.19- .96) and more than 5 years (OR: .16, 95% CI: .04-.63) were significantly associated with negative attitude. The confidence score for managing COVID-19 (OR:1.16, 95% CI:1.02-1.34) was significantly associated with an optimistic attitude. Conclusion Healthcare workers are knowledgeable about COVID-19 and proactively practising to minimize the spread of infection but lack optimistic attitudes. Hence, the constantly updated educational programmes related to COVID-19 for targeted groups will contribute to improving healthcare workers' attitude and practices.

An outbreak investigation of scrub typhus in Nepal: confirmation of local transmission. BMC Infect Dis 2021; 21:193. [PMID: 33602136 PMCID: PMC7893900 DOI: 10.1186/s12879-021-05866-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 02/02/2021] [Indexed: 12/13/2022] Open
Abstract
Background Scrub typhus is a largely ignored tropical disease and a leading cause of undifferentiated febrile illness in the areas of tsutsugamushi triangle caused by Orientia tsutsugamushi. It is frequently diagnosed in South Asian countries, although clear epidemiological information is not available from Nepal. After the 2015 earthquake in Nepal, a sudden upsurge in scrub typhus cases was reported. The objective of this study was to investigate epidemiology of scrub typhus and its causative agents in humans, animals, and chigger mites to understand the ongoing transmission ecology. Methods Scrub typhus cases with confirmed diagnosis throughout the country were included in the analysis. Studies were concentrated in the Chitwan district, the site of a major outbreak in 2016. Additional nation-wide data from 2015 to 2017 available from the government database included to analyse the disease distribution by geographical mapping. Results From 2015 to 2017, 1239 scrub typhus cases were confirmed with the largest outbreak occurring in 2016 with 831 (67.1%) cases. The case fatality rate was 5.7% in 2015 which declined to 1.1% in 2017. A nationwide outbreak of scrub typhus was declared as the cases were detected in 52 out of the 75 districts of Nepal. Seasonal trend was observed with a peak during August and September. In addition to the human cases, the presence of O. tsutsugamushi was also confirmed in animals (rodents) and chigger mites (Leptotrombidium imphalum) from the outbreak areas of southern Nepal. Conclusion The detection of O. tsutsugamushi in humans, animals, and chigger mites from outbreak locations and wide-spread reports of scrub typhus throughout the country consecutively for 3 years confirms the ongoing transmission of O. tsutsugamushi with a firmly established ecology in Nepal. The country’s health system needs to be strengthened for systematic surveillance, early outbreak detection, and immediate actions including treatment and preventive measures.

Genetic Diversity of Astrovirus in Children From a Birth Cohort in Nepal. Front Microbiol 2021; 11:588707. [PMID: 33613461 PMCID: PMC7893100 DOI: 10.3389/fmicb.2020.588707] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Accepted: 12/21/2020] [Indexed: 11/27/2022] Open
Abstract
Objective: This study describes the types of Human astroviruses detected in stool samples collected from a birth cohort of children in Nepal. Methods: Using a commercial kit (ProSpecT), a total of 5,224 diarrheal and non-diarrheal stool samples were screened for Human astrovirus by ELISA. RT-PCR was performed on ELISA positive samples (2.8%) for further confirmation. The primary RT-PCR assay used targets the ORF2 region and detects human astrovirus type 1–8. Samples that were negative in this assay were further analyzed using primers that target the ORF1b region of human astrovirus which detect both classical type (HAstV 1–8) and novel types (MLB1–5, VA 1–5). PCR positive samples were analyzed by Sanger sequencing to determine the genotype. Results: A total of 148 available ELISA positive stool samples were analyzed by RT-PCR and further genotyped. RT-PCR analysis of these samples using the ORF2 and ORF1b assay revealed that 124 (84%) were positive for classical human types (HAstV 1–8). Seven different classical HAstV genotypes based on ORF2 and ORF1a were identified (HAstV 1- HAstV 8) with the greatest prevalence of HAstV 5 genotype (42.2%), followed by HAstV 1 (34.7%), HAstV 2 and HAstV 8 (7.4%), HAstV 4 (4.1%), HAstV 3 (3.3%), and HAstV 6 (0.8%). Non-classical types were not detected in our study. Conclusion: A high diversity of circulating Astrovirus strains were detected in young children, both with and without symptoms of gastroenteritis. HAstV 5 and HAstV 1 were the most common genotypes in young children in Nepal.

Abstract
Enveloped viruses like Coronavirus acquire their envelope from the host cell membrane which is a bilayer of phospholipid interspersed with cholesterol molecules and proteins. Viruses enter their host cell by coming in contact with their specific receptors. Experiments have shown that when cell membranes are depleted of cholesterol in vitro by Methyl beta cyclodextrin (MβCD) these Coronaviruses are not able to enter the host cell membrane by the process of receptor mediated endocytosis. Statin inhibits HMG Co-A reductase, a key enzyme in the Mevalonate pathway resulting into either very low or no production of endogenous cholesterol by the human cells. This results into upregulation of LDL-R in the cell membrane which may lead to more cholesterol getting incorporated into the cell membrane through LDL-C from the plasma creating greater number of lipid rafts suitable for entry of enveloped viruses by receptor-mediated endocytosis.

Abstract
Campylobacter is the most common cause of traveler's diarrhea (TD) and human bacterial gastroenteritis. A heteroresistant Campylobacter jejuni (C. jejuni) isolate, identified by microbiological methods and characterized with molecular techniques, was obtained from a traveler in Nepal suffering TD. The presence of atypical colonies within the clear zone of inhibition was the first evidence of an atypical phenotype, leading to additional characterization of this heteroresistant strain. Antimicrobial susceptibility testing (AST) and population analysis profiling (PAP) demonstrated heteroresistance to azithromycin (AZM), a first-line antibiotic treatment for Campylobacter infections. Molecular analysis indicated a point mutation occurred on the 23S rRNA gene at the A2075G transitions, and the number of mutated gene copies was proportional to AZM resistance. Heteroresistant C. jejuni subpopulations from acute TD are likely underestimated, which may lead to treatment failures, as was the case for this patient. The presence of a heteroresistant strain in a high antibiotic environment may select for additional drug resistance and enable distribution into hospital and local communities.

Abstract
Background Nepal lacks a unified and countrywide emergency medical services system as other developing countries. However, the emergence of ambulance service initiatives in the past decade shows a promising future for pre-hospital care. Nepal Ambulance Service (Est. 2011) and Dhulikhel Emergency Medical Services (Est. 2013) are the existing emergency medical services initiatives in Nepal. Objective To describe the reason for summoning ambulance services and demographics of the patients who were transported by Dhulikhel Emergency Medical Services at Dhulikhel hospital, hilly region of Nepal. Method One thousand three hundred and ninety three patient records at Dhulikhel hospital transported by Dhulikhel Emergency Medical Services during the five-year period (2013 - 2018) were included in the study. Chief complaints and demographic data were collected and categorized into overarching systemic categories. Result Among 1393 patients, majority were female (60.4%) and the most common age group was 20-29 years. The most common reason for calling ambulances was gastrointestinal problem (22.6%). Similarly, respiratory (17%), obstetric and gynecological (15.2%), trauma (12.7%) and neurological (9.6%) problems were other common reasons. The number of respiratory problem was increased during the winter season. The overall percentage of patients arriving at hospital with trauma problems was increased steadily, but it was not statistically significant. Conclusion Gastrointestinal problem was the most common reason, followed by respiratory and obstetric and gynecological problems for summoning ambulances services in the hilly regions of Nepal. The incidence of respiratory problem significantly increased during the winter season.

Abstract
Background Acute renal colic is the most frequent clinical presentations of renal stone and a common cause of patient visits to emergency departments worldwide. The prevalence of the renal stone disease has increased steadily over the past decades. Objective To describe the prevalence, epidemiological features and clinical management of renal colic patients at emergency department in Kathmandu University Hospital, Kavre, Nepal. Method Two hundred and thirty-six patients with acute renal colic presented in emergency department during a six-months period were included in the study. Using a standard predesigned proforma, demographic characteristics, presenting symptoms, practice of pain management and outcome were investigated. Renal colic attacks in patients were defined according to International Classification of Diseases, Tenth Revision, and Clinical Modification-10. Result Prevalence of renal colic was 2.61%. Mean age of the patients was 33.9±13.7 years. More than half of participants were male (54%). Majority of the patients (47.9%) were from Kavrepalanchowk district. The most common presenting symptom of the patients was flank pain on affected side (79.2%). In almost 43% of patients, diclofenac sodium was administered as a first line analgesic. There was no significant difference between diclofenac and ketolorac with respect to the need of second line analgesic (Chi-square value: 0.19, p value = 0.664). Conclusion Prevalence of renal colic was 2.61% at Dhulikhel hospital. More male pateints were affected and the most common presenting symptom was flank pain on the affected. Diclofenac and ketorolac are equally effective for the pain management of renal colic patients.

Abstract
Introduction: Accurate assessment of fluid status in hemodialysis patients presents a significant challenge. Nephrologists have long relied on dry weight estimation based solely on clinical parameters to decide the ultrafiltration volume for patients with end-stage kidney disease on dialysis. However, this method is far from accurate and many patients recurrently suffer from signs and symptoms of fluid overload or circulatory collapse from overaggressive ultrafiltration. Invasive methods such as measurement of central venous pressure cannot be used routinely. We evaluated the usefulness of inferior vena cava (IVC) diameter measured by handheld ultrasound in the estimation of fluid status in patients before and after hemodialysis. Materials and Methods: Clinical assessment included patients’ symptoms, weight, blood pressure, heart rate, and presence of edema before and after dialysis session. Dry weight was assessed based on the above parameters. Each patient underwent measurement of inferior vena cava before and after hemodialysis. The anteroposterior IVC diameter (IVCD) was measured 1.5 cm below the diaphragm in the hepatic segment in supine position during normal inspiration and expiration.Results: Thirty hemodialysis patients (mean age 51.6±18.03 years) were evaluated in outpatient dialysis unit. Following hemodialysis mean IVCe (IVC diameter in expiration) decreased from 1.40±0.38 to 0.91±0.30 cm (p<0.001). Similarly, mean IVCi (IVC diameter in inspiration) decreased from 0.67±0.34 to 0.35±0.19 cm (p<0.001). Changes in IVCD were significantly correlated with alterations in body weight following dialysis (p<0.0001). The IVC collapsibility index (IVC-CI, per cent of change in IVC diameter in expiration vs. inspiration) increased significantly from 0.53±0.18 to 0.68±0.18 after dialysis (p=0.002). IVC diameter and IVC-CI clearly reflected alterations in fluid status. Regarding the clinical parameters of fluid status, following hemodialysis, mean heart rate increased from 81.17±5.21 beats per minute to 86.50±7.99, (p=0.003), systolic blood pressure increased from 148.67±26.36 mmHg to 155.00±28.50, (p=0.05), and diastolic blood pressure increased from 78.62±12.74 mmHg to 84.83±14.55, (p<0.001).Conclusions: Our findings support the applicability of IVCD measurement and IVC-CI in the estimation of fluid status in end stage kidney disease patients on hemodialysis. The clinical parameters of fluid status including heart rate, systolic blood pressure, and diastolic blood pressure suggest that significant numbers of patients underwent excess ultrafiltration based on their traditional dry weight calculation. Thus, using IVC parameters before and during hemodialysis might give a better estimation of fluid status of the patient and guide the amount of ultrafiltration to be done.

Abstract
BACKGROUND The evidence is mixed on the use of long chain Omega-3 fatty acids in the prevention and management of childhood asthma. METHODS We conducted a systematic search and meta-analysis investigating the role of fish intake, the main dietary source of long chain omega-3 fatty acids, on asthma in children. RESULTS A total of 1119 publications were identified. Twenty-three studies on fish intake in association with childhood asthma were included in the final review. In 15 of 23 studies, early introduction of fish (6-9 months) and regular consumption (at least once a week) improved asthma symptoms and reduced risk in children 0-14 years as compared to no fish consumption; 6 of 23 showed no effect and 2 of 23 studies suggest adverse effects. Meta-analysis revealed an overall "beneficial effect" for "all fish" intake on "current asthma" [OR: 0.75; 95%CI: 0.60-0.95] and "current wheeze" [OR: 0.62; 95%CI: 0.48-0.80] in children up to 4.5 years old. An overall protective effect of "fatty fish" intake as compared to "no fish" intake in children 8-14 years old was also observed [OR: 0.35; 95%CI: 0.18-0.67]. CONCLUSION This meta-analysis suggests that introduction of fish early in life (6-9 months) and regular consumption of all fish (at least once a week) reduces asthma and wheeze in children up to 4.5 years old, while fatty fish intake may be beneficial in older children. Future well-designed clinical trials are recommended to confirm the promising findings documented in this literature analysis.

Abstract
OBJECTIVE Asthma is a prevalent non-communicable disease both in low- and high-income countries, including Nepal. Total serum immunoglobulin E levels and peripheral blood absolute eosinophil counts are known inflammatory markers of asthma. Fractional exhaled nitric oxide measurement in breath has also been proposed as a non-invasive biomarker to assess eosinophilic airway inflammation. This study explores the correlation between these three variables with the intent that one may replace the other in resource-limited setups. APPROACH This prospective controlled trial evaluated 314 subjects with and without asthma, with the asthma group sub-divided into atopic and non-atopic categories. Total serum immunoglobulin E level, absolute eosinophil count in peripheral blood and fractional exhaled nitric oxide level were measured in all categories. RESULTS The geometric mean of immunoglobulin E levels, absolute eosinophil count and fractional exhaled nitric oxide were 221.07 ± 774.55 IU/mL, 214 ± 360/uL and 37 ± 49 ppb in the asthma group and 59.13 ± 174.32 IU/mL, 164 ± 137/uL and 12 ± 21 ppb in the control group, respectively. Significantly higher levels were seen in the asthma group for total serum immunoglobulin E (p < 0.001), AEC (p = 0.002) and FENO (p < 0.001) levels. Total serum immunoglobulin E levels, absolute eosinophil count and fractional exhaled nitric oxide were 436.79 ± 822.40 IU/mL, 269 ± 395/uL and 76 ± 52 ppb in atopic asthma group. Similarly, total serum immunoglobulin E levels, absolute eosinophil count and fractional exhaled nitric oxide were 131.17 ± 692.96 IU/mL, 182 ± 328/uL and 23 ± 22.5 ppb in non-atopic asthma group. Significantly higher levels were seen in all three variables: tIgE (p < 0.001), AEC (p = 0.008) and FENO (p < 0.001). A moderate degree of positive correlation was identified between tIgE and FENO50 (Spearman's rho = 0.461) and tIgE and AEC (Spearman's rho = 0.315) with only small correlation between FENO50 and AEC (Spearman's rho = 0.299). SIGNIFICANCE tIgE levels, FENO50 and AEC levels are higher in asthma, specifically in the atopic phenotype, as compared to normal. Total serum IgE levels have moderate correlation with FENO50 and AEC but FENO50 and AEC are weakly correlated.

Abstract
BACKGROUND AND OBJECTIVES Astroviruses are important drivers of viral gastroenteritis but remain understudied in community settings and low- and middle-income countries. We present data from 8 countries with high prevalence of diarrhea and undernutrition to describe astrovirus epidemiology and assess evidence for protective immunity among children 0 to 2 years of age. METHODS We used 25 898 surveillance stools and 7077 diarrheal stools contributed by 2082 children for enteropathogen testing, and longitudinal statistical analysis to describe incidence, risk factors, and protective immunity. RESULTS Thirty-five percent of children experienced astrovirus infections. Prevalence in diarrheal stools was 5.6%, and severity exceeded all enteropathogens except rotavirus. Incidence of infection and diarrhea were 2.12 and 0.88 episodes per 100 child-months, respectively. Children with astrovirus infection had 2.30 times the odds of experiencing diarrhea after adjustment for covariates (95% confidence interval [CI], 2.01-2.62; P < .001). Undernutrition was a risk factor: odds of infection and diarrhea were reduced by 10% and 13%, respectively, per increase in length-for-age z score (infection: odds ratio, 0.90 [95% CI, 0.85-0.96]; P < .001; diarrhea: odds ratio, 0.87 [95% CI, 0.79-0.96]; P = .006). Some evidence of protective immunity to infection was detected (hazard ratio, 0.84 [95% CI, 0.71-1.00], P = .052), although this was heterogeneous between sites and significant in India and Peru. CONCLUSIONS Astrovirus is an overlooked cause of diarrhea among vulnerable children worldwide. With the evidence presented here, we highlight the need for future research as well as the potential for astrovirus to be a target for vaccine development.

Abstract
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.

Abstract
Background In many developing countries, emergency medical services, especially pre-hospital emergency care, has long been neglected. It is the major obstacle for provision of timely care. Patients are regularly brought to emergency department by the relatives in taxis, bus or other readily available mode of transportation that lacks emergency medical services. Development the Nepal Ambulance Service established its first proper ambulance service in Nepal in 2011 and Dhulikhel Emergency Medical Services in 2013 at Dhulikhel Hospital, Kathmandu University Hospital. Proper prehospital emergence medical service can improve survival rates. Objective To determine the mode of transportation used by patients to arrive at the emergency department and effectiveness of medical services specific to Dhulikhel Hospital, Kavre, Nepal. Method In this study, 160 patients who arrived to emergency department during one-month period were included. The emergency physicians and paramedics collected data on a predesigned questionnaire regarding demographic details, mode of transport used by the patients to arrive emergency department, reason for not using ambulance, knowledge on emergency medical services at Dhulikhel Hospital and their acceptability for those services. Result Mean age of the patients was 46±18 years and (52%) were men. Out of them, only 31% arrived to the emergency department by ambulance while the rest other patients used other forms of transport such as private vehicles (21%), bus (16%), taxi (13%), motorbike (11%) and van (7%). Among 50 patients who used ambulance, 24% of the patients who used Dhulikhel Hospital ambulance received medical care and trained medical staff services; all patients were satisfied with the services. 155 out of 160 patients mentioned the need of a trained medical personal in ambulance. The mean duration for waiting time for ambulance was 33.78 minutes. The main reasons to not using ambulance were they did not know the ambulance number, ability to find other vehicles easily and having own private vehicle. Conclusion A prominent proportion of patients did not arrive by ambulance to the emergency department and the main reason was that they didn't know the number of ambulance service. Developing three-digit phone number for ambulance service at the local level will make people easier to remember and contact. Similarly, education and training must be developed to improve emergency medical services. These strategies along with team management of patients could significantly improve patient care in Nepal.

Abstract
Dengue virus (DENV) is expanding toward previously nonendemic areas. DENV has recently been introduced in Nepal with limited information. We report the clinical features and serotype distribution of DENV in Nepal during the 2010 outbreaks. A total of 1,215 clinical dengue cases at two major hospitals of central and western Nepal were investigated. Demographic, clinical, and laboratory parameters were recorded. Serum specimens were tested for DENV by IgM/IgG enzyme-linked immunosorbent assays (ELISAs) and reverse transcription polymerase chain reaction (RT-PCR). We confirmed DENV infection in 403 (33%) patients from 12 districts with an estimated case fatality rate of 1.5%. DENV infection was more common in adults (87%) and urban settings (74%). We detected all four serotypes but DENV-1 and -2 were mainly responsible for major outbreaks (92%). Overall, 60% of all DENV infections were secondary and 17% were severe dengue; both being more frequent among the DENV-2 infections. Rash, bleeding, abdominal pain, hepatomegaly, elevated liver enzymes, and thrombocytopenia were significantly more common in severe dengue compared with nonsevere infections. We also confirmed the expansion of dengue to hill urban areas (DENV-1 and -2), including the capital Kathmandu (altitude, 1,300 m) though > 90% cases were from southern plains. Differential clinical and laboratory features probably help in clinical decisions. Multiple serotypes circulation and elevated secondary infections pose potential risk of severe outbreaks and deaths in the future. Therefore, a country with recent dengue introduction, like Nepal, urgently requires a systematic surveillance and appropriate control measures in place to respond to any disastrous outbreaks.

Abstract
Background Pulmonary hypertension (PH) often complicates Chronic Obstructive Pulmonary Disease (COPD). Sildenafil reduces pulmonary arterial pressure associated with multitude of diseases. Objective To evaluate the use of Sildenafil in Pulmonary Hypertension associated with COPD. Method This randomized control study enrolled 72 patients: 61 completed the study. Thirtypatients with COPD received Sildenafil 25 mg thrice daily and 31 patients with COPD received optimal medical therapy for four weeks. Symptom assessment and dyspnoea grading was done with modified Borg scale and Modified Medical Research Council (MMRC) grade. The functional assessment was done with WHO functional classification. The estimation of pulmonary arterial systolic pressure and six minute walking distance was done before and after four weeks of the administration of therapy in both groups. Adverse reaction profiling was done for Sildenafil. The primary outcomes were the changes in pulmonary arterial systolic pressure and six minute walk test. The secondary outcomes were change in modified Borg scale for dyspnoea, MMRC grading and WHO functional class. Result The mean decrease in pulmonary arterial systolic pressure in Sildenafil group was significant as compared to controls (9.87+7.84 mmHg Vs 5.93+7.44 mmHg, P=0.048). The mean increase in six minute walk distance was significantly more in cases as compared to controls (48.13+25.79 m Vs 32.59+32.96 m,P=0.047). The changes in modified Borg scale was not significant (1.20+1.92 to 1.55+1.23; P=0.401). There was significant changes in MMRC grade (p=0.037). There was no significant change in WHO functional class after four weeks (p=0.071). Conclusion Sildenafil marginally decreased pulmonary arterial systolic pressure and increased six minute walk distance in COPD patients. It improved MMRC grading without affecting modified Borg's Scale and WHO functional class.

Abstract
Introduction: Massive lower extremity trauma,in particular open tibial fractures with associated vascular injuries, present an immediate and complex decision-making challenge between a limb salvage attempt and primary amputation. Medical and surgical advances of the past two decades have improved the ability to reconstruct severely injured limb. Limbs that once would have been amputated are now routinely managed with complex reconstruction protocol. Mangled extremity severity score is one of the scoring systems to predict the fate of limbs after severe limb injuries.Methods: Patients fulfilling the inclusion criteria were evaluated with MESS, at the same time treatment protocol for management of injuries of lower limb were followed independently by attending orthopedic surgeon. Mean MESS for salvaged and amputated limbs were calculated and its reliability for prediction of fate of injured limb was assessed using software SPSS v16.Result: The age of patient ranges from 10 to 65 yrs with mean age 35.83. The most common mechanism of injury was Road Traffic Accident followed by fall from height. The mean MESS score for salvaged limbs was 4.18 and for amputated limbs was 8.12 suggesting significant difference in mean scores. The sensitivity (the probability that limbs requiring amputation will have MESS at or above 7) was found to be 75%. The specificity of MESS (the probability that salvage limbs will have MESS < 7) was 95.45%.Conclusion: MESS is a reliable indicator in decision making process whether a limb can be salvaged or needs amputation. The mangled lower extremity with the score of less than 7 may be salvaged and 7 or more may need amputation.JSSN 2015; 18 (1), Page: 23-25

Abstract
Introduction: Distal tibial fractures present as a major challenge for the orthopedic trauma surgeons. Most non-operative treatments result in non-union or malunion and needs prolonged immobilization of the knee and ankle joints, with resulting stiffness. Open reduction and internal fixation as well as external fixation has high rate of infection and non-union. Minimally Invasive Plate Osteosynthesis has been shown to have a better outcome and has been the procedure of choice in most distal tibial fractures since the introduction of the locking compression plate. The objective of the study is to review the outcome of Minimally Invasive Percutaneous Osteosynthesis (MIPO) in unstable distal tibial fractures.Methods: Charts of patients who underwent MIPO from the year 2008 to 2013 for unstable distal tibial fractures over five years at Patan Hospital and Om Hospital were reviewed. All displaced closed fractures and Gustillo Anderson Type I and II fractures were included in the study. Plates consisted of the anatomically contoured 4.5 mm LCP and 3.5 mm LCP-Pilon form plate. A simple uniplanar external fixator was used to retain the reduction till the plate was inserted and secured with locking screws. The outcome of MIPO in distal tibial fractures were followed up and evaluated. Clinical and radiological assessments were performed at 6 weeks, and at 3, 6, 9, 12 and 24 months.Results: Of the 75 patients (45 male, 30 female) age ranging from 19 to 70 years (mean 47 years), 5 patients were lost to follow-up. 28 patients at 3 months, 32 at 6 months, and 8 at 9 months met the criteria for a healed fracture. Two patients required autologous bone grafting at 9 months for non-union ultimately resulting in the fracture union at 16 months. There was one malunion attributable to the loss of reduction during plate fixation. There were no deep infections, no soft tissue complications and no failures of fixation. The cause of fracture were RTA (n=35), fall from height (n=9), twisting of ankle as a result of fall from standing height (n=22), and others (n=11). The mean time for surgery from the time of injury was 5 (range, 2 to 14) days; the mean hospital stay was 10 (range, 7 to 21) days.Conclusion: MIPO is an effective treatment for closed, unstable fractures of the distal tibia, avoiding the complications associated with more traditional methods of internal fixation and/or external fixation.Journal of Society of Surgeons of NepalVol. 17, No. 2, 2014, Page: 7-11

Abstract
INTRODUCTION Anal fissure is an ischemic ulcer caused by combination of spasm of internal anal sphincter and poor blood supply to the posterior midline of anal canal. This study aimed to assess the efficacy of Glyceryl Trinitrate and Nifedipine in the treatment of chronic anal fissure. METHODS Ninety patients with symptomatic anal fissure in Kathmandu Medical College Teaching Hospital are allocated for study in two groups of 45 each from March 2013 to April 2014. The patients are assigned alternatively to GTN group and Nifedipine group. All patients were assessed every week till 8 weeks in regards to headache, compliance, healing and recurrence. The patients who had complete healing in 8 weeks were further followed up for 6 weeks to detect recurrence. RESULTS Patients in the two groups were comparable in regard to demographic data (age and sex) as well as clinical factors. Headache was main complaint of patients using GTN in high percentage (16.6%) than complained by patients using topical Nifedipine (6.9%). This factor led to poor compliance with GTN compared with Nifedipine. Nifedipine showed better healing rate 82.5% compared with GTN 60%. Recurrence was comparable among the two groups. CONCLUSIONS Nifedipine ointment showed better results than GTN ointment in chronic anal fissure regarding headache, compliance, healing and recurrence in 6 weeks of follow up period after complete healing of fissure in 8 weeks.

Abstract
BACKGROUND Laparoscopy surgery trials are small and unconvincing at present and are limited to higher centers. The objective of the study is to determine the clinical features, prevalence of site of hydatid cyst and complications of this modality of this treatment. METHODS A cross sectional study was carried out in all patients with one or two hepatic hydatid cyst who underwent laparoscopic management in KMCTH from January 2013 to March 2015 were included in the study. Aspiration, deroofing and evacuation of the hydatid cyst were done. RESULTS Twenty six patients underwent laparoscopic management for liver hydatid cysts. Males were seven (65.38%) and females were 9(34.61%).The mean age was 35.5±13.1 years (range 21-55years.) The commonest complaint was pain and discomfort in 13(50%) patients and lump in 6(13.06%) patients. Twenty four (92.3%) patients were successfully treated with laparoscopic approach. Two (7.69%) patients had to be converted to laparotomy because of dense adhesions and bleeding. Mean operation time was 43.6±10.6 minutes. Two (7.69%) patients had port site infection. One (3.84%) patient had bile leak and no recurrence and mortality in our series. CONCLUSIONS Laparoscopic management of liver hydatid cyst was safe and effective in selective group of patients in equipped hospital.

Abstract
Introduction: Pancreatic cysts are common (2.5%). Cystic neoplasms represent 10% of cystic lesions and 1% of pancreatic tumors. However, it is difficult to differentiate benign cyst from malignant cystic lesions preoperatively.Objective: To study the cases of pancreatic cystic lesion who underwent various forms of pancreatic resection.Materials and Methods: Nine cases of pancreatic cystic lesion who presented to Kathmandu Medical College Teaching Hospital, Surgical Unit 3 within December 2014- November 2015 were evaluated. Four pancreatic cysts who underwent resection are discussed whereas not managed with resection are excluded.Results: There were 4 cases of pancreatic cyst who underwent pancreatic resection. First case underwent pancreaticoduodenectomy for pancreatic mucinous cystadenoma. However histopathological examination revealed a serous cystadenoma. In second case, pancreatic neck lesion suspected to be mucinous cystadenoma or pseudocyst in MRCP, with negative malignant cells in EUS guided FNAC underwent Central pancreatectomy and was found to be serous cystadenoma. The third case with suspected pseudocyst underwent Pancreaticoduodenectomy after a 3X2 cm2 cystic mass was felt at the posteroinferior side of pancreatic head and malignancy was suspected intraoperatively . HPE report was mucinous cystadenoma. The fourth case with pancreatic pseudocyst at tail with duct calculi and chronic pancreatitis underwent distal pancreatectomy with splenectomy with Frey’s procedure.Conclusion: Management of pancreatic cystic lesion is challenging. Though radiological imaging has limited role in accurate diagnosis, endoscopic ultrasound may be of some benefit.

Abstract
Introduction and Objective: The frontiers of liver resection are expanding. Future Liver Remnant; its volume, function and complication have a predictive value in post resection outcome including post resection liver failure. This study is directed to discuss the issues related to future liver remnant.Objective: To discuss issues related to Future Liver Remnant in patients planned for major liver resectionMaterials and Methods: Data of patients admitted for liver resection at Kathmandu Medical College Teaching Hospital, Surgical Unit III with varied diagnosis, were collected prospectively over a period of 1 year. In our non transplant center, Future Liver Remnant was managed with varying methods. Of the 12 liver resections, 3 prototype cases with different FLR issues are discussed in this study.Results: The first case had issue related to the volume of the liver remnant for which she underwent a portal vein ligation followed by resection (after adequate volume increase) in the second surgery. The second case was a Hepatocellular Carcinoma with CTP 8 cirrhosis. Despite adequate liver volume, decision for liver resection was delayed due to possible postoperative decompensation. The third patient was a Hilar cholangiocarcinoma with obstructive jaundice. Biliary decompression (PTBD) was performed. However, inadequate fall in bilirubin caused dilemma for liver resection. Despite the dilemma, all 3 cases underwent liver resection with no postoperative liver failure.Conclusion: Issues related to the volume and function of future liver remnant in patient undergoing liver resection should be adequately addressed by various pre operative, intra operative, and post operative measures.

Abstract
Background Transversus abdominis plane block has been recently developed as a part of multimodal post operative analgesic techniques. We compared the analgesic efficacy of this technique with local bupivacaine infiltration in patients undergoing gynaecological surgeries with pfannenstiel incision and lower midline incision under general anaesthesia.Objectives To evaluate the efficacy of ultrasound guided transversus abdominis plane block for postoperative analgesia.Methods Patients were randomly allocated to three groups: control group (n=15), transversus abdominis plane block group (n=15), who received bilateral transversus abdominis plane blockwith 0.25% bupivacaine, and local infiltration group (n=15), who received local wound infiltration with 0.25% bupivacaine at the end of surgery. All patients received intramuscular diclofenac 12 hourly and intravenous tramadol SOS in the postoperative period. Visual analogue scores for pain were assessed at 1,2,4,8,12 and 24 hours postoperatively and these were compared between the three groups. Average tramadol consumption in 24 hours were also compared among the three groups. Data were subjected to univariate ANOVA test and chi-square test. Level of significance was set at 0.05.Results Visual analogue scores were significantly less in transversus abdominis plane block group and effect lasted up to 12 hours at rest postoperatively and 8 hours during cough and movement.Conclusion Bilateral Transversus abdominis plane block was effective in reducing postoperative pain scores for 8 to 12 hours postoperatively. This block was also successful in reducing postoperative opioid requirement.Kathmandu University Medical Journal Vol.12(2) 2014: 93-96

Abstract
BACK GROUND AND OBJECTIVES Fracture of the distal radius is the most common fracture treated by the orthopedic surgeons. Although there are several treatment options available today, the aim always remains to restore the anatomy and bring back the function to near normal condition. In this prospective study we intend to evaluate the functional and radiological outcome of the unstable fracture of the distal radius when treated with external fixator. MATERIALS AND METHODS In this hospital based, Prospective study conducted in department of Orthopedics, College of Medical Sciences Teaching Hospital, Bharatpur, Chitwan, during the period from January 2011 to September 2012, 54 patients, (33 male and 21 female) with unstable fracture of the distal end of radius were included in the study. All the patients were treated with external fixator and followed for a period of 12 weeks. RESULT Among 54 patients, 52 were followed up for 12 weeks and two patients were lost to follow up after six weeks. The final result was assessed in detail on the basis of Modification, by Sarmiento et al., of the Demerit Point system of Gartland and Werley at the end of 12 weeks. The result was excellent in 25 cases, good in 19 cases and fair in eight cases. There were no poor results in this series. CONCLUSION External fixator is not only easy to use, allows re-reduction, has lower rate of complications and can be stiff enough to maintain the alignment but it is also a cost effective, patient compliant method which causes lesser morbidity to the patient as compared to the other options available.DOI: http://dx.doi.org/10.3126/jcmsn.v10i2.12950Journal of College of Medical Sciences-Nepal, 2014, Vol.10(2); 27-32

Abstract
INTRODUCTION Safe dissection of Calot's Triangle is important during the performance of laparascopic cholucystectomy. The purpose of the study is to determine the frequency of demonstrable Rouviere's sulcus in patients with symptomatic gall stones and its role in safe dissection in Calot's triangle. METHODS This is a prospective descriptive study design done in Department of surgery, Kathmandu Medical College Teaching Hospital from Jan 2013 to Jan 2015. Patients who were posted for laparoscopic cholecystectomy were included. During laparoscopy, Rouviere's sulcus was noted in the operative note and classified according to following: Type I: Open type was defined as a cleft in which the right hepatic pedicle was visualized and the sulcus was opened throughout its length. Type II: if the sulcus was open only at its lateral end. Type III If the sulcus was open only at its medial end. Type IV: Fused type was defined as one in which the pedicle was not visualized. RESULTS A total of 200 patients underwent laparoscopic cholecystectomy during period of 2 years. Out of which Rouviere's sulcus was visualized in 150 patients (75 %).Type I (open type) was commoner in 54%, type II in 12%, Type III in 9% and type IV (fused type) in 25%. CONCLUSION Rouviere's Sulcus is an important extra biliary land mark for safe dissection of Calot's triangle during laparoscopic cholecystectomy.

Abstract
BACKGROUND Influenza virus (IFV) isolates obtained from mammalian cell cultures are valuable reagents used for vaccine production, antigenic characterization, laboratory assays, and epidemiological and evolutionary studies. Complete genomic comparison of IFV isolates with their original clinical specimens provides insight into cell culture-driven genomic changes which may sequentially alter the virus phenotype. OBJECTIVES The genome of the viral isolates and of the viruses in the clinical specimens was examined by deep sequencing in order to determine nucleotide heterogeneity (measured number of variances or numbers of mixed bases) as a marker for IFV population diversity. STUDY DESIGN Clinical respiratory specimens were collected between July and October 2012 and identified by RT-PCR as positive for influenza A H3N2 or H1N1, or influenza B. The viruses in the clinical specimens were amplified using mammalian cell culture. Next generation sequencing (NGS) was used to investigate genomic differences between IFV isolates and their corresponding clinical specimens. RESULTS There was less nucleotide heterogeneity in 5 of 6 viral isolates compared to the corresponding clinical specimens, especially for influenza B. A phylogenetic analysis of the hemagglutinin (HA) gene consensus sequences obtained from deep and Sanger sequencing showed that the viral isolates and their corresponding clinical specimens contained the same IFV strains with less than 5% pair-wise genetic distance. CONCLUSION The IFV sequence data analysis detected a substantial decrease in nucleotide heterogeneity from clinical specimens to viral cultures in 5 out of 6 investigated cases.

Abstract
Background Acute febrile illness is common among those seeking medical care and is frequently treated empirically with the underlying illness remaining undiagnosed in resource-poor countries. A febrile illness study was conducted 2009-2010 to identify known and unknown pathogens circulating in Nepal. Method Study methods included diagnostic testing and preliminary ELISA screening of acute and convalescent samples for diseases both known and unknown to be circulating in Nepal, including West Nile virus (WNV). The molecular assays including Polymerase Chain Reaction (PCR), Sanger sequencing and ultra deep sequencing on MiSeq Illumina Platform were conducted to further confirm the presence of WNV. Results The study enrolled 2,046 patients presenting undifferentiated febrile illness with unknown etiology. Sera from 14 out of 2,046 patients were tested positive for west nile virus (WNV) by nested Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Only two out of 14 cases were confirmed for the presence of WNV by sequencing and identified as WNV lineage 1 phylogentically. The two patients were adult males with fever and no neurological symptoms from Kathmandu and Bharatpur, Nepal. Conclusion Two out of 2,046 serum samples contained fragments of WNV genome resembling WNV lineage 1, which is evidence of the continued spread of WNV which should be considered a possible illness cause in Nepal.

Abstract
BACKGROUND Physical trauma is one of the major cause of mortality and morbidity among young and active age group and its increasing trend is of main concern. There are only few studies concerning the spectrum of physical trauma in Nepal. OBJECTIVE This study aims to evaluate the epidemiological spectrum, the extent, severity of the physical trauma and the outcome evaluation of patients with physical trauma over a period of one year in the emergency department of the Kathmandu University Hospital and compare the same parameters with those patients presenting to the various outreach centers of the hospital in the community. METHODS Patient treatment files from the emergency department and the reports from various outreach centers were retrieved for a period of one year (May 2011 to April 2012). Epidemiological information, mode, type and anatomic location of injuries were recorded. Outcome evaluation was assessed by number of patients discharged from emergency department of the hospital or the outreach centers after the treatment, patients admitted for inpatient management and referred to other centers for further specialty management. RESULT In a period of one year, total 2205 (20%) of physical trauma cases presented to the emergency department and 1994 (6.12%) in the outreach centres. Most commonly involved age group in physical trauma both in Hospital set up and in Community set up were the young adults (15 to 49 years). Fall from height was the commonest mode of injury followed by road traffic accidents among the patients coming to the hospital while significant number of trauma patients coming to outreach centers were due to fall from height. In the hospital set up, 1525 (69.2%) of the cases were discharged while 537 (24.4%) needed inpatient management and 85 (3.8%) needed referral to other centers for the specialty management. In case of outreaches, half of the patients were discharged after the primary treatment and almost another half were referred to the hospital, mainly for need of further investigations. CONCLUSION Fall related injuries and road traffic accidents are the most common mode of trauma in the hospital set up and fall related injuries are the single most important mode of trauma seen in the outreaches. Mostly young adults in their active period of life are involved in physical trauma so appropriate preventive measures through public health approach should be included in comprehensive trauma management for reducing mortality and morbidity rates related to physical trauma.

Abstract
BACKGROUND Fentanyl, a synthetic opioid, is a popular choice amongst anaesthesiologists in the operating room. Pre induction intravenous fentanyl bolus is associated with coughing in 28-65% of patients. Fentanyl induced cough is not always benign and can be remarkably troublesome at the most critical moment of anaesthesia when airway reflex is lost. OBJECTIVES To study the effect of pre emptive use of minimal dose fentanyl through the peripheral venous cannulae on the incidence of cough by a larger bolus of intravenous fentanyl. METHODS One hundred and fifty patients aged 18-75 years undergoing elective surgical procedures were randomized into three groups of 50 each. The first group received 0.5 ml saline 0.9% intravenously one minute prior to the administration of fentanyl 150 μg (3 ml); the second group received pre emptive fentanyl 25 μg (0.5 ml) prior to the administration of fentanyl 125 μg (2.5 ml); and the third group received preemptive fentanyl 25 μg (0.5 ml), followed by the administration of fentanyl 150 μg (3 ml). Based on the number of coughs observed, cough severity was graded as mild (1-2), moderate (3-5), or severe (>5). RESULTS The incidence of fentanyl induced cough was significantly lower in both pre emptive group 4 (8%) for 125 μg fentanyl and 7 (14%) for 150 μg than in the saline group 15 (30%). CONCLUSION Pre-emptive use of minimal dose fentanyl 25 μg administered one minute before a larger bolus dose of fentanyl (125 or 150 μg) can effectively suppress cough.

Abstract
Introduction: Pheochromocytoma is a rare tumor, originating from the chromaffin tissue. Its frequency is approximately 1/100,000. The clinical manifestation is due to catecholamine excess, which includes high blood pressure, palpitation, headache, sweating, nausea, vomiting, trembling, weakness, irritation, abdominal and chest pain, dyspnea, red warm face, constipation, polyuria, and polydipsia.
Case Report: We present a case of 53 years old male, hospitalized for hypertensive crisis following the manipulation of left sided frozen shoulder. He had labile blood pressure ranging from 220/120 systolic- 90/60 diastolic, profuse sweating and tachycardia. Findings of Contrast enhanced CT of abdomen was consistent with right adrenal pheochromocytoma and 24 hours urinary VMA was 17 mg /24 hr (Normal <13.6 mg /24hr). After the clinical, paraclinical investigations and radiological tests, it was proved to be a pheochromocytoma. The surgical intervention was planned. But due to unavailability of required antihypertensive drugs in Nepal (alpha-blockers like phentolamine and phenoxybenzamine), surgeons were reluctant to operate, although blood pressure was well controlled with use of sodium nitroprusside during hypertensive crisis and prazosin, a selective alpha blocker as maintainance therapy. The use of prazosin to control hypertension secondary to pheochromocytoma is limited to case report and case series.
Conclusion: Although rare, pheochromocytoma is a treatable surgical cause of secondary hypertension.

Abstract
In Nepal, febrile illness is one of the most common reasons for seeking medical attention, but there is limited information on the frequency of specific etiology of fever. This is a retrospective study. Patients presented with fever admitted in medicine ward and Intensive care unit of KIST Medical College, Imadol, Lalitpur from January 2010 to January 2012 are included in the study. Of the 898 patients enrolled, 23.5% had infective exacerbation of COPD. Enteric fever, urinary tract infection, acute gastroenteritis, tuberculosis and community acquired pneumonia were the cause of fever in 20%, 13%, 10%, 7.3% and 6% cases of respectively. Findings confirm the heavy burden of infection was a cause of fever requiring hospitalization. This highlights the importance of simple diagnostic tests and cost effective treatment required to manage these patients.

Abstract
Background The ability of good glottis visualization during direct laryngoscopy is major determinant of easy tracheal intubation. Sniffing position for laryngoscopy is considered as gold standard and ideal position. Several studies have questioned the validation of sniffing potion. Objectives This study aims to compare relative efficacy of sniffing position and simple head extension for visualization of glottis during direct laryngoscopy. Methods Four hundred patients undergoing elective surgery under general anesthesia requiring endotracheal intubation were randomized into two groups and study was concluded. Glottic visualization was assessed using modified Cormack and Lehane classification. After laryngoscopy, tracheal intubation was performed and intubation difficulty scale was noted. Results Both the groups were comparable regarding glottis visualization. Both the groups were comparable in demographic profiles. All the intubation difficulty scale variables were comparable in both the groups except N3. Total Intubation Difficulty Score was better in sniffing position than in simple head extension group. Conclusion Glottic visualization and intubation difficulty score was better in sniffing position as compared to simple head extension.http://dx.doi.org/10.3126/kumj.v9i1.6265 Kathmandu Univ Med J 2011;9(1):58-63

Abstract
BACKGROUND Isolated fractures of metacarpals and phalanges are the commonest injuries affected upper extremity, which constitute about 10% of skeletal fractures in general. Fifth metacarpal (boxer's fractures) being the most common. The objective of this study was to investigate the outcome of treatment of the displaced neck and sub-capital fractures of the fifth metacarpal by percutaneous K wire fixation. METHODS An observational study was conducted in the department of orthopedics Patan hospital as an outpatient procedure from January 2010 to January 2012. All adult patients with unilateral fracture of neck of fifth metacarpal bone were included. Whose physis was open, having previous hand injury or diseases causing deformity or impaired hand function and when fracture was more than 7 days old, were excluded from the study. RESULTS Twenty eight of 35 patients obtained anatomic reduction, and 7 patients had 2/3 apposition of bone end and no rotational deformity. Follow-up was available for only 30 patients. The follow-up time was up to 12 weeks. The head/shaft angle of the fifth metacarpal was 60.60 degrees ±9.39 degrees preoperatively, and 14.20 degrees ±7.32 degrees postoperatively, and 15.60 degrees ±6.95 degrees in 12 weeks postoperatively. The difference between preoperative and postoperative angles was highly significant. The range of motion of the metacarpal joint was 86.73 degrees ±6.13 degrees postoperatively, which was not significantly different compared with that of uninjured side which was 90.93 degrees ±3.18. The difference between preoperative and postoperative angles was highly significant. The range of motion of the metacarpal joint was not significantly different compared with that of uninjured side. The average union time was 5.46 weeks ±1.22. CONCLUSIONS This method under consideration does not disturb the fracture site itself, the Kirschner wire being introduced in retrograde fashion makes it easier to correctly place the wire, which gives reasonably stable fixation, gives excellent results in a high proportion of selected cases. Local anesthesia is an added advantage.

Abstract
BACKGROUND Ureteral stones present with acute loin to groin pain. The objective of this study is to find out the outcome and safety of semi-rigid ureterscopy with pneumatic lithotripsy for treatment of ureteral stones of >30 mm(2) and to assess the impact of size and location on stone free (SF) rate. METHODS Total 110 patients with isolated ureteral stone size>30 mm(2) were included in this study and treated with pneumatic lithotripsy using 8/9.8 Fr. Semi-rigid ureteroscope (Stiema Germany). Stones were fragmented into 2-3 mm particles and removed. Outcome parameters assessed at 3 months follow up were stone free rate(SF),Efficiency Quotient (EQ), and impact of stone size and site on SF/EQ was also analyzed. Similarly, patient demographics, procedures, patient related parameters and complications were also noted. RESULTS The overall SF rate at 3 months follow up was 69.33% and efficient Quotient (EQ) 52.52%. The SF/EQ for upper, middle and lower third of ureteral stone was 55/37.67, 61/43.57, 92/84.40 respectively (P-value< 0.001). The SF for stone size 30-110 mm(2) and >110 mm(2) was 78% and 67% respectively. There were no major complications seen. Overall minor complication rate was 5.45 % (minor ureteral perforations-5, urinoma formation 1). CONCLUSIONS Semi-rigid ureteroscopy with pneumatic lithotripsy is a safe, simple and effective procedure for ureteral stones with excellent success rate for distal ureteral stones. The stone free rate and EQ are statistically significant (P value<0.001) between upper, middle and lower ureteral stones. Stone size has a direct impact on the SF rate and EQ.

Abstract
BACKGROUND A current assessment of liver abscesses should allow for better understanding of the pathogenesis of the disease and improve the effectiveness of diagnosis and treatment. Amoebic liver abscess occurs more commonly than the pyogenic liver abscess on a worldwide basis. The purpose of the study is to investigate the clinical presentation and management option for liver abscess. METHODS A prospective observational study was conducted from January 2007 to December 2010, in Kathmandu Medical College Teaching Hospital. We recorded and analyzed the clinical presentations, diagnostic modalities, treatment programmes of all liver abscesses. RESULTS Liver abscess was more common in males, 24(85.7%) males and 4(14.3%) females, occurring more frequently in right lobe of liver. Most patients presented with nonspecific clinical and biochemical features. Twenty (71.4%) patients presented with chills & rigors. Five patients (17.8%) presented jaundice and none had transaminases raised but 15(56.3%) had raised alkaline phospahatases. Eight (28.5%) patients were treated with antibiotics alone. USG guided drainage was done in 12(42.8%) patients and 6(21.4%) required surgical exploration with laparoscopic deroofing in 2(7.1%) patients. The largest size was 1100cc.with right lobe predominance in 20(76.9%) patients and single lobe involvement in 22(78.4%) patients. Six (21.4%) patients had multiple liver lobes involved. Three (7.1%) patients had ruptured liver abscess and 3(7.1%) had right sided pleural effusion. Seventeen (60.7%) patients were diagnosed have amoebic liver abscess. Ten (35.7%) patients were found to have pyogenic liver abscess. One (3.5%) had tuberculosis. CONCLUSIONS Liver abscess requires a high degree of suspicion for early diagnosis. When appropriate therapy in the form of antibiotics in combination with percutaneous drainage or surgery is administered the mortality is very low. However, significant morbidity is still a problem in old debilitated persons with other core morbidities.

Abstract
The ideal surgical treatment of spondylolisthesis still remains controversial. There are several methods of treatment and posterior lumbar interbody fusion (PLIF) is one of them. We analyze the results of spondylolisthesis treated by PLIF in term of radiological union, improvement of pre-operative symptoms like back pain, radiating pain and return to normal activities including that of employment, by the review of the medical records. Total of 72 patients, 20 male and 52 female and the age ranges from 15 to 68 years with the mean age being 44.38 years were included in the study. Thirty (41.66%) patients had isthmic spondylolisthesis, 26 (36.12%) had congenital spondylolisthesis, and 16 (22.22%) cases had degenerative spondylolisthesis. There were 38 (52.77%) cases of grade I, 14 (19.44%) cases of grade II and 20 (27.77%) cases of grade III according to the grading criteria of Meyerding. According to the evaluation criteria used by Stauffer and Coventry, 59 patients (81.94%) got good results, eight patients (11.11%) belonged to the fair group and five cases (6.94%) had the poor results. This study showed that PLIF is one of the effective and reliable techniques for the management of spondylolisthesis.

Abstract
BACKGROUND Although laparoscopic appendicectomy is now a common practice, it has not become the gold standard like in cholecystectomy. Aim of our study is to compare with operation time and hospital stay found in available literatures. METHODS All laparoscopic appendicectomies performed between January 2004 and February 2009 were retrospectively reviewed for age, sex and operation time length and hospital stay. Appendicitis with signs of perforation was treated by open midline laparatomy and the ones with lump formation were treated conservatively. RESULTS A total of 48 patients underwent laparoscopic appendicectomies during this period (female 26 and male 22) and mean age was 27.2 years (6-77). The mean operating time was 56.6 minutes (40-120 minutes). The mean hospital stay was 4.7 days (3-8 days). CONCLUSIONS Laparoscopic appendicectomy is a feasible and safe in simple appendicitis. Although the number of cases of laparoscopic appendicectomies is a small for five year period, the mean operation time and mean hospital stay is comparable to the literatures.

Abstract
BACKGROUND Caudal analgesia with bupivacaine is used commonly for pain relief in children and extradural administration of tramadol seemed to be a safe method of analgesia. The aim of the study is to compare the analgesic efficacy of caudal bupivacaine and bupivacaine and tramadol mixture for postoperative analgesia and to observe for side effects. METHODS Forty children, aged between 1- 6 years undergoing infra umbilical surgeries were selected for this randomized, control trial. They were randomly divided into two groups. Group A (n = 20) received 0.5 ml/kg of 0.25 % bupivacaine and Group B (n = 20) received 0.5 ml/kg of 0.25 % bupivacaine with 1 mg/kg of tramadol as a single shot caudal block. In the postoperative period heart rate, respiratory rate, pain score, recovery to first analgesic time, total number of analgesics required in 24 hours and side effects were noted and analyzed. RESULTS It was observed that the mean duration of pain relief was significantly longer in Group B (8.8 hrs Vs 7 hrs). Nausea and vomiting was observed in 25% of the patients in group B and 20 % of the patients in group A. None of the patients in both the groups had complication like motor weakness, urinary retention in the postoperative period. CONCLUSIONS The addition of tramadol to bupivacaine in the caudal analgesic technique provides longer analgesia and lesser need for rescue analgesic in the postoperative period compared to bupivacaine.

Abstract
Enteric fever is one of the common public health problems in Nepal. This study was carried out at Nepal Medical College Teaching Hospital located at peri-urban area in Kathmandu Valley to find out the prevalence of enteric fever and the sensitivity pattern of the Salmonella isolates. A total of 479 patients with fever were included in the study. Venous blood samples collected aseptically were subjected to culture and were studied following the standard bacteriological procedure. The overall prevalence of enteric fever was 5.4% (26/479). Of them more than half (65.4%) were caused by S. paratryphi A whereas remaining (34.6%) by S. typhi. The positive rate was higher in children aged 1-15 years (8.9%) followed by 15-30 years of age (4.3%) and others (1.9%). Gender wise, females to male ratio was 1.4:1. The occurrence of infections was higher in Dalit (7.1%), Khas (Brahmin and Chhetri) (5.9%) and Madeshi (5.9%) whereas lowest was in Adibasi Janajati (4.8%). Prevalence rate of enteric fever among different sex, age and ethnic group was not significant (p > 0.05). Isolates were highly sensitive to Amikacin (100.0%) and Ciprofloxacin (96.1%) whereas least sensitive to Gentamycin (68.7%).

Abstract
INTRODUCTION Laparoscopic surgery is unique and complex in nature, so the training is necessary before proceeding to operation room. Many computer aided simulators have been developed for the purpose. Our objective is to assess the improvement of basic laparoscopic skills after training in simulator. METHODS The fifth year medical students underwent training of three laparoscopic skills using Promis2 simulator twice weekly for 4-6 weeks. The skills are laparoscopic orientation, target pointing and objects transferring. Time, path length of instruments and economy of movements were recorded. The comparisons were made for these parameters between session first and the last using a Mann-Whitney U test. RESULTS Ten volunteers completed the exercises in less time (186.3 +/- 55.4 seconds) than the first exercise (215.7 +/- 57.4 seconds) (P=0.0027). Both the right and left hand instrument path lengths were also improved from 4425.8 +/- 1284.3 mm in the first exercise to 3925.3 +/- 1313.6 mm in the last exercise in the left side (P=0.0219) and likewise from 4273.8 +/- 1859.4 mm to 3831.3 +/- 1717.4 mm in the right side (P=0.0027). Economy of the movement in the left handed instrument improved from 1114.4 +/- 453.5 mm in the first exercise to 966.8 +/- 411.1 mm in the last (P=0.0443) and in the right handed instrument from 845 +/- 398.8 mm to 771.4 +/- 370.5 mm according to the software of Promis2 simulator (P >0.005). CONCLUSIONS Training in Promis2 simulator improves the basic laparoscopic skills. The candidates become consistently faster with shorter path lengths and had smoother instruments movements. They also became significantly more consistent in their performance.

Abstract
Slipped capital femoral epiphysis (SCFE) is a common adolescent problem in the western populations but it is extremely rare in the Asian regions. We report a case management of a teen age boy (16 years old at the time of operation) with bilateral SCFE. After fall injury, the boy sustained SCFE on the left side and was treated. Again after six months with trivial injury he got SCFE on the right side. In both cases the boy was managed by closed reduction and percutaneous cannulated cancelleous screws fixation under c-arm fluoroscopy control. The cannulated screws were removed after one year of insertion confirming of a good fusion in plain x-ray films. During the regular follow up of up to one year the patient had good hip functions and other daily activities. The patient lost to follow up for about three years and suddenly presented to us with restricted hip joints movements and other activities. The x-ray showed tilted pelvis, reduced, incongruent hip joint spaces with malunited femoral physis, widened neck and tilted femoral head along with visible physeal scan on both sides. The patient and patient party are still satisfied with these results and reluctant to go for further surgical intervention.

Abstract
Supracondylar fractures of humerus in children are common injuries. Displaced fractures areinherently unstable. Conservative treatment results in malunion. Open reduction and internalfixation (ORIF) is more invasive and recovery is prolonged. From September 2004 to September 2005, 102displacedsupracondylarfractures of humerus, agedbetween one andhalf yearto 13 years, weretreated using close reduction and percutaneous Kirschner (K) wire fixation under c-arm fluoroscopy. Seventy nine patients were treated by cross K-wires and in twenty three cases lateral two K-wireswereput.Above elbow plaster ofparis back slab was appliedinall cases for atleastfour weeks.Backslab,K-wireswere removedafterfourweeks andelbowrangeofmotionexercisewas started.Resultswere analyzed using Flynn’s criteria. All patients were followed up to 14th week postoperatively. Incross K-wire group(N=79) 70.8% had excellent, 22.7% good, 3.8% fair and 2.5% had poor results at eight weeks follow up which was improved to 91.1% excellent, 6.3 good, 1.2% fair and 1.26% poor results at 14 weeks follow up. In lateral K-wire group (N=23) 70% had excellent, 21.7% good, 4.3% fair and 4.3% had poor result at eighth week which was improved to 91.3% excellent, 4.3% good, 4.3% fair and no poor result at 14th week follow up. Eight patients got superficial pin tract infection and seven patients sustained ulnar nerve injury post operatively.We recommend this procedure fordisplacedsupracondylarfractures inchildrenas itis safeandcost effectiveprocedurewithacceptablecomplication rates.Key words: closed reduction, humerus, percutaneous pinning, supracondylar fracture
