Publication 64-Slice CT Scan in Kathmandu Medical College Teaching Hospital(Kathmandu University, 2008) Karki, DB; Neopane, A; Regmi, S; Acharya, SAbstract 64-slice CT scan is a versatile newly introduced imaging technology, which is capable of diagnosing various diseases from head to toe. The 64-slice CT coronary angiography has a negative predictive value of 100%. Virtual images of bronchi, stomach and colon can provide definite diagnosis. Coronary artery calcification score which predicts coronary artery disease can be calculated by 64-slice CT scan. Key words: coronary angiography, coronary calcificationPublication A review on percutaneous coronary intervention vs. coronary artery bypass graft surgery.(Kathmandu University, 2003) Karki, DB; Neopane, ANAPublication A Study of the First 350 Cases Referred for EEG in Kathmandu Medical College Teaching Hospital(Kathmandu University, 2004) Shrestha, R; Pradhan, SN; Sharma, SC; Shakya, KN; Karki, DB; Rana, BBS; Joshi, LNElectroencephalography or EEG is a neurological test that uses an electronic monitoring device to measure and record electrical activity in the brain. Epilepsy is defined as a recurrent tendency to unprovoked seizure. About 0.5% to 2% of the population has epilepsy. Material and Methods This is a retrospective study of the first 350 odd cases referred for EEG at Kathmandu Medical College Teaching Hospital, Kathmandu during period November 2002- September 2002 (Mangsir 2058- Bhadra 2059). Results Most patients fall in the age group of 11-20 years and more than 50% referred cases fall in the prime of life, i.e., 11- 30 years. 16% of patients with the history of seizure did not use any AED and 32 % who though had no history of seizures were actually using AED. It is seen that out of 149 reported normal, 57 (38%) had history of seizure; but out of 208 reported abnormal in EEG only 92 (42%) had history of seizure. Discussion EEG is not a very sensitive or a specific tool; however, in our study it was seen to be more sensitive than specific. It is till very useful in classifying seizure types, in locating epileptic focus prior to surgery or in some confusing situation when movement disorder may simulate seizure disorder or vice versa. Conclusion Although EEG is not a very sensitive or specific investigation, it is more sensitive than specific.Publication A Typical Case of Myasthenia Gravis(Kathmandu University, 2003) Poudel, M; Angel, GM; Neupane, A; Karki, DBNA.Publication Acute haemorrhagic conjunctivitis: an epidemic in august/ September 2003(Kathmandu University, 2003) Karki, DB; Shrestha, CD; Shrestha, SObjective: To clinically analyze 400 cases of red eye attending Nepal Eye Hospital in August/ September 2003 and to study the aetiology of the disease on the clinical basis with available laboratory resources. Materials and methods: It is a prospective study of 400 cases of acute conjunctivitis visiting Nepal Eye Hospital during the epidemic of acute haemorrhagic conjunctivitis in August/September 2003. Result: 30.5% presented in the age group of 20-29 years. Males presented predominantly (73.3%). Maximum number of patients presented at two days of onset of symptoms. All 400 cases had red eye, 89.8% had pain, 86.3% had foreign body sensation and 87.5% had discharge. Bilateral involvement was seen in 73.5% and unilateral involvement in 26.5%, 4.3 % of the total cases had corneal involvement and 20% of the cases had associated fever and preauricular lymphadenopathy. Conclusion: Based on clinical presentation and the report of available laboratory results, picorna virus was found to be responsible for this epidemic of acute haemorrhagic conjunctivitis. Keywords: Haemorrhage, Conjunctivitis, Superficial Punctate Keratitis, Lymphadenopathy, Picorna virus.Publication An Overview of Undergraduate and Postgraduate Medical Education in Nepal and Elsewhere(Kathmandu University, 2004) Karki, DB; Dixit, HThough Health Sciences education started in the country as far back as 1934, it was only in 1978 that the MBBS course was started. The first postgraduate (PG) course, which was started, was the MD in general practice, which was started in 1982. It is over the course of the last 22 years, and more specifically after 1993, that there has been a spurt in postgraduate (PG) education. The rapid increase of medical schools / colleges within the country during the last decade, has been the main reason for fulfilling the demand of doctors with postgraduate degrees required for different faculty positions at the newly established medical colleges. This article also looks at the role of foreign qualifications vis-à-vis the local degree for the development of PG programmes within the country. Key words: Postgraduate degree, diplomas, Nepal Medical Council.Publication An update on pulmonary arterial hypertension(Kathmandu University, 2007) Karki, DB; Neopane, A; Regmi, SNAPublication Analysis of 400 cases of posterior segment diseases visiting retina clinic of Nepal eye hospital(Kathmandu University, 2003) Karki, DB; Malla, OK; Byanju, RN; Shrestha, SObjective: To determine the disease pattern of 400 patients attending Nepal Eye Hospital for strategic planning. Materials and methods: A retrospective hospital based analysis of 400 cases visiting Retina Clinic of Nepal Eye Hospital (NEH) over a period of one year was carried out in order to know the disease pattern for planning purpose. Results: Males slightly outnumbered females (58% versus 42%). The diseases were more common in age group 50 to 59 years. Diabetes mellitus with or without retinopathy was the commonest cause (20.25 %) for attendance in retina clinic followed by hypertensive retinopathy and venous occlusive disorders. Keywords: Posterior segment disease pattern, diabetic retinopathy, hypertension, venous occlusive disease.Publication Atrial Fibrillation: How should it be treated?(Kathmandu University, 2007) Karki, DB; Neopane, A; Regmi, SNAPublication Changing spectrum of antibiotic sensitivity in enteric fever(Kathmandu University, 2008) Neopane, A; Singh, SB; Bhatta, R; Dhital, B; Karki, DBAbstract Aims and objectives: The study was designed to analyze clinical profile and Antibiotic sensitivity pattern in case of culture positive typhoid fever and compare response of quinolones in vitro and in vivo. Methodology: Forty eight cases of culture positive enteric fever presented in outpatient and emergency department of Kathmandu Medical College, Sinamangal, and Kathmandu were included in the study. Sensitivity pattern of isolates from blood culture was done by antibiotic disc diffusion method and this was compared with clinical response. Results: Response was based on Fever Clearance Time (FCT) and it was found that mean FCT was 3.58 days with standard deviation of 1.84 .Comparison was made separately for FCT ≥5 days and it was found that vomiting as the symptom and stool occult blood positive as the investigation to predict prolong FCT. Nalidixic acid as compared with other quinolones showed that other quinolones (ciprofloxacin, ofloxacin) are effective even in Nalidixic acid resistant cases when FCT was taken as the criteria of response, and it doesn’t include the relapse rate. Conclusion: Enteric fever is one of the leading causes of fever in Nepal. The diagnosis in most of the cases is done empirically by clinical features, but culture and sensitivity of blood or bone marrow is the gold standard way of diagnosis and providing treatment. The antibiotic sensitivity pattern is changing and resistance cases are emerging with indiscriminate use of drugs. Key words: Enteric fever, Salmonella typhi, fever clearance time (FCT), antibiotic sensitivity test (AST)Publication Clinical profile of typhoid patients(Kathmandu University, 2003) KC, Mathura; Gurubacharya, DL; Shrestha, A; Pant, S; Basnet, P; Karki, DBObjective: The present study was undertaken to determine the clinical profile of typhoid fever in hospitalised patients. Design: Prospective cross-sectional study. Setting: Kathmandu Medical College and Teaching Hospital Method: Total of thirty patients above fifteen years of age who had clinical features strongly suggestive of typhoid fever and on blood culture found to be positive for salmonella typhi were analysed for clinical features. Result: Among total of thirty cases, there were 17 (57%) males and 13(43%) females. 86% of cases of typhoid fever clustered around 15-30 years of age. Predominant symptoms were fever (100%), headache (90%), abdominal Pain (37%) and constipation (33%). Common clinical signs were splenomegaly (37%), relative bradycardia (27%) and hepatomegaly (17%). None of the patients presented with complications. Conclusion: The clinical profile of typhoid fever in our study revealed not much difference from that of other studies on typhoid fever. Rose spots were not noticed and we did not find a single case of complication of typhoid fever. Probably early initiation of antibiotics prevented the complications. Key words: Typhoid fever, S. Typhi.Publication Effectiveness of nicotinic acid and bezafibrate alone and in combination for reducing serum triglyceride level(Kathmandu University, 2005) Pradhan, B; Neopane, A; Karki, S; Karki, DBObjective: To study the effectiveness of nicotinic acid and Bezafibrate alone and in combination for reducing triglyceride level. Design: It was a randomised, prospective, longitudinal study. Setting: Patients attending a private clinic, and medical department of Kathmandu Medical College, Sinamangal. Methods: This study included 83 consecutive patients, 19 females and 64 males with hypertriglyceridaemia (defined as serum triglyceride >200mg/dl) attending the department of medicine, Kathmandu Medical College, Sinamangal and private clinic. Main outcome measures: Statistically significant reduction of serum triglyceride level. Result: 51 out of 83 patients completed the study in which Nicotinic acid alone reduced the serum trygleceride level from 320.62 ± 104.23 to 182.55 ± 46.21, which is a reduction of 138.07 ± 85.69 (P. value = 001). Bezafibrate when given alone also reduced triglyceride level significantly from 345.25 ± 181.03 to 203.30±93.59 which is a reduction of 141.95 ± 121.130 (P value= .001). When a combination of both drugs was given the reduction of 472.73±247.53 (P value =.002) was achieved. Conclusions: Nicotinic acid is a very effective drug in reducing serum triglyceride level and its effectiveness is similar to Bezafibrate. There is no added benefit of giving a combination of nicotinic acid and Bezafibrate in reducing serum triglyceride level. Keywords: Hypertriglyceridaemia, Nicotinic acid, Bezafibrate.

Design: Prospective observational study Setting: Kathmandu Medical College, Teaching Hospital, Kathmandu, Nepal Materials and methods: febrile patients with clinical diagnosis of enteric fever were included in the study with the aim of confirming diagnosis with blood culture, or bone marrow culture and evaluating the diagnostic accuracy of various clinical signs and symptoms. Results: 64% of the clinically diagnosed cases had blood/ bone marrow culture positive. The diagnostic accuracy of the various symptoms and signs excluding fever was between 42%-75.5%. Majority of the symptom and sign did not have very high diagnostic accuracy. Hence a diagnostic criterion was proposed and clinical features with diagnostic accuracy more than 50% were taken into consideration. Major criteria included fever with diagnostic accuracy of 64%, headache with accuracy of 75.5% and relative bradycardia with an accuracy of 66%. Minor criteria included vomiting, diarrhoea, Splenomegaly, chills and abdominal pain /discomfort with diagnostic accuracy of 57%, 55%, 55%, 53% and 51% respectively. Finally after combination of various major and minor criteria a final diagnostic criterion was proposed having an accuracy of 66% and including both major and minor clinical symptom and sign. Conclusion: clinical diagnosis of enteric fever will be very helpful in a country like ours. Though none of the clinical symptoms and sign have very high diagnostic accuracy a diagnostic criteria may be helpful. Criteria including both major and minor signs and symptoms would be the most appropriate diagnostic tool as it includes the important abdominal symptoms and signs of enteric fever. Key words: enteric fever, clinical features, diagnostic criteriaPublication Injection drug use and tricuspid valve endocarditis(Kathmandu University, 2005) KC, Mathura; Thapa, N; Rauniyar, A; Magar, A; Gurubachharya, DL; Karki, DBTricuspid valve endocarditis is more common in injection drug users. Pulmonary valve and Eustachian valve endocarditis have been reported but are very rare. Earlier reports of endocarditis in injection drug users emphasized the dominance of right sided involvement. In a series of 105 patients 86 % were right sided and 14 % had left sided involvement. We report a case of isolated tricuspid valve endocarditis in an injection drug user affecting a structurally normal heart and review of the literature on this subject. Key Words: injection drug use, tricuspid valve endocarditisPublication Lipid levels in Nepalese population(Kathmandu University, 2004) Karki, DB; Neopane, A; Pradhan, B; Magar, AObjective: To study the lipid pattern of Nepalese population Design: Retrospective study Setting: Patients attending Temple of Healing for consultation Methods: Fasting lipid profile of 2218 blood samples was analyzed. Results: Abnormal total cholesterol(TC) was found in 7.7%. High LDL cholesterol(LDL-C) was found in 5% of cases. 70% of subjects had triglyceride(TG) level more than the upper level of normal. All abnormal lipid level was found in the age group 49-60years. 23% of the study group had low level of HDL cholesterol. Conclusions: abnormal triglyceride level is the commonest lipid abnormality in our population. High total cholesterol and LDL cholesterol is not very common except in the age group 40-49 where it is significantly high in comparison to other age groups. HDL cholesterol level did not decrease significantly with increasing age. Keywords: Lipids, Nepalese populationPublication Management of Typhoid fever in the Department of Medicine at Kathmandu Medical College(Kathmandu University, 2003) Dhakal, M; Neopane, A; Subedi, N; Dhakal, R; Karki, DBAim 1. To assess the ongoing management strategy of typhoid fever in department of medicine at Kathmandu Medical College, Sinamangal, Kathmandu. 1. To suggest changes, if required for the benefit of patients and doctors Method Prospective study of clinically suspected enteric fever from 2060/01/29 to 2060/04/25. Assessment and analysis of the rationality of the diagnostic parameters that are being used in the ward for clinically suspected enteric fever in unit one of department of medicine. Treatment outcome of the patients with the commonly used antibiotics. Analysis of the sensitivity pattern of the salmonellae isolated among the study group. Result 1. Only 11 cases (37%) were actually culture proven among the 30 cases suspected to be enteric fever on clinical basis. 2. 19 cases (63 %) of the clinically suspected enteric fever were diagnosed only on the basis of single widal test (titre more than 1:320), blood culture being negative. 3. Bone marrow was subjected to culture for salmonella only in 4 Cases (13%) despite blood culture being sterile. 4. The laboratory could provide sensitivity pattern of salmonellae only in 5 cases out of 11 culture positive cases (45%). 5. Eighteen cases (60%) had to be given 3rd generation cephalosporin after not responding to 5 days course of fluoroquinolones (ciprofloxacin or ofloxacin). On the other hand all the cases in the study group subjected to 3rd generation cephalosporin (injection ceftriaxone or cefixime orally) responded well to the treatment. Conclusion 1. We shouldn’t be relying too heavily on a single titre of widal test for the diagnosis of enteric fever and should be sending blood for culture for salmonella and even bone marrow culture, if necessary. This can be concluded on the basis of lots of literature against single widal test in the diagnosis of enteric fever. 2. Widal test should be positive with clearly significant rising titre (with paired sample) or modified widal test has to be performed if one wants to give gravity to the test for the diagnosis of enteric fever. 3. Laboratory personnel’s need to be more serious in their works so as to try to see sensitivity pattern in all positive cultures, if rational use of antibiotics is really desired in view of increasing antibiotic resistance. 4. Fluoroquinolones, once thought to be super powerful antibiotic & still taken as the drug of choice almost everywhere, has been found to be resistant in most of the cases in this study. Though the sample size is too small and there are lots of limitations in this study to come to a firm conclusion, it has borne one serious question in the minds of our unit doctors: Correspondence Dr. Mahesh Dhakal Dept. of Medicine, Kathmandu Medical College, Teaching Hospital Kathmandu University Medical Journal (2003) Vol. 1, No. 3, 197-204 198 whether we are over-using fluoroquinolones for trivial infections and leading to the emergence of resistant strains of salmonellae?Publication Marfan’s syndrome with aortic valve endocarditis(Kathmandu University, 2004) Jaiswal, S; Magar, BS; Poudel, M; Joshi, LN; Neupane, A; Karki, DBMarfan’s syndrome is an Autosomal dominant disorder of the connective tissues resulting in abnormalities of the musculoskeletal system, cardiovascular system and eyes. It has a prevalence of 1 in 100,000 population1 and occurs in all ethnic groups. It may be familial or due to new mutation (30%), in the fibrillin gene on arm of chromosome 15. It is estimated that one person in every 3000-5000 has Marfan’s syndrome may have cardiovascular abnormalities and may be complicated by infective endocartditis. About 90% of Marfan patients will develop cardiac complications2. The patient under discussion has musculoskeletal (Tall stature, reduced upper-lower segment ratio, arm-span to height ratio >1.05, high arched palate) and Cardiovascular features (Severe aortic regurgitation complicated with infective endocarditis) Key words: Marfan’s Syndrome, Autosomal dominant, Aortic Regurgitation, Infective EndocarditisPublication Publication Study of patients presenting with symptoms of peripheral neuropathy and thickened greater auricular nerve(2003) Neopane, A; Upadhyaya, B; Dungana, S; Karki, DBObjective: To analyze symptoms and make a clinical diagnosis of leprosy in patients presenting with symptoms of peripheral neuropathy and found to have thickened greater auricular nerve. Design: Cross- sectional study Setting: Kathmandu Medical College Teaching Hospital, Sinamangal, Kathmandu. Patients attending the medical out patient department of this hospital were taken in the study. Materials and methods: 40 patients presenting with symptoms of peripheral neuropathy and are found to have thickened greater auricular nerve were included. Results: Thickened greater auricular nerve and sensory symptoms showed male predominance (97.5%). Mean age of involvement was 28.65 years. The symptom most frequently complained of was chest pain (75%), followed by pins and needle sensation 67.5%, burning of the upper extremities, nape of the neck and chest 57.5%, palpitation 45%, disturbed sleep mostly said to be due to burning 35%, sweating 20%, dizziness17.5%, shortness of breath 7.5%, and numbness of the limbs in 2.5%. None of the patients had somatic neuropathy. Autonomic neuropathy was present in 42.5 %. Conclusions: 1. In endemic areas patients with thickened peripheral nerve and sensory symptoms should be diagnosed clinically as primary neuritic leprosy. 2. In absence of objective loss of somatic sensation autonomic neuropathy may be the only early indicator of neuritis. 3. Close follow up of these patients is necessary. Key words: peripheral neuropathy, primary neuritic leprosy, autonomic neuropathy, follow upPublication Two cases of severe falciparum malaria in KMCTH(Kathmandu University, 2006) Singh, SB; Chaudhary, D; Neopane, A; Karki, DBMalaria is the most important parasitic disease of man. It is the protozoan infection of RBCs transmitted by bite of blood feeding female anopheline mosquito. Until the 19th century malaria was found throughout Europe, North America and Russia. Since then, it has been eradicated from these areas but in tropics though initial efforts of eradication had been successful, there has been resurgence of disease1 accompanied by increasing resistance of the anopheline vector to insecticide and of the parasite to antimalarial drugs. We report two cases of falciparum malaria in which there was co-existent vivax malarial infection. These two cases were both exposed to highly endemic zone for malaria. Key words: Sequestration, malaria, falciparum.
