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.

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 Clinico-radiological profile of stroke in eastern Nepal: A computed tomographic study(Kathmandu University, 2006) Naik, M; Rauniyar, RK; Sharma, UK; Dwivedi, S; Karki, DB; Samuel, JRAim: Stroke is a frequent cause of death and disability in elderly patients. This study was carried out to establish the pattern of various types of cerebrovascular accident (CVA) in eastern Nepal and to correlate the clinical data and radiological findings in cases of stroke. Materials and methods: All the patients clinically diagnosed as stroke and referred to the radiology department for Computed tomography (CT) of the brain over a period of 1 year were included. Results: There were 150 patients with stroke (104 males and 46 females), aged 7 to 91 years in which infarction (58%) was more common than haemorrhage (42%) in both group of age (≤ 40 years and > 40 years). Smoking was the commonest risk factor noted in 40.66% cases followed by hypertension (40%). Excessive meat consumption (more than 4 times a week) was seen in 69.1% cases. In early Middle Cerebral Artery (MCA) territory infarction presenting within six hours of onset, positive CT findings were seen in 40% cases among which, obscuration of the lentiform nuclei was diagnostic. Conclusion: In this part of Nepal, infarction is more common than haemorrhage as the cause of stroke and in contrary to western population; hemorrhagic stroke constitutes a significantly higher proportion of stroke. Smoking is the commonest risk factor followed by hypertension and it is also seen in combination with alcohol in many cases. Excessive meat consumption could be an additional risk factor for stroke in this part of Nepal. In younger age group (≤ 40 years), haemorrhage is more common than infarction and alcohol consumption is the commonest risk factor.

Material and methods: Our study included 32 patients with ascites, demonstrated by ultrasonography, who had measurement of the SAAG. All had upper gastrointestinal endoscopy with assessment of the presence and size of EV. High SAAG was considered to be present when SAAG was >= 1.1 g/dl and Low SAAG when it measured < 1.1 g/dl. Results: We found that 25 of 32 (78.13%) patients had High SAAG and 7 of 32 (21.87%) had Low SAAG. Esophageal varices were present in 18 of 25 (72%) patients with High SAAG and in none of 7 (0%) patients with Low SAAG (p =< 0.001). Among patients with High SAAG, EV were present in four of 8 patients (50%) with SAAG values of 1.10-1.49g/dl; in four of seven patients (57.1%) with SAAG values of 1.50-1.99g/dl; and in ten of ten (100%) with SAAG values of >= 2.0g/dl (p = 0.037). The size of the esophageal varices had no association with the level of SAAG in patients with High SAAG (p = 0.426). Conclusions: In patients with ascites the presence of esophageal varices is associated only with patients with High SAAG. The presence of EV in patients with ascites and High SAAG is directly related to the degree of SAAG. The size of the EV in patients with ascites and High SAAG is not associated with the degree of SAAG.

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.

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 Intermediate uveitis: a hospital based study(Kathmandu University, 2004) Malla, OK; Karki, DB; Byanju, RN; Shrestha, SIntermediate uveitis affecting pars plana, peripheral retina and underlying choroid affects primarily healthy children and young adults. Objective: To study the components of intermediate uveitis at Nepal Eye Hospital in the year 2003 August to 2004 March. Materials and Methods: A prospective study was done in patients with intermediate uveitis visiting Nepal Eye Hospital. Sample size was 50. Specially designed proforma of intermediate uveitis was used to collect particulars of the patients, history, clinical examination findings, investigation reports, management protocols used and the final visual outcome. Results: Intermediate uveitis was seen more in 20 to 29 years age group (38%) and more prevalent in males (52%). Among the study population farmers constituted maximum proportion (36%) and Mongoloid origin was mostly affected (30%). High number of patients were from the central development region with highest proportion from Dhading district (34%). Anterior segment affection with keratic precipitates and anterior chamber cells were noted in 72% of involved eyes. Vitreous cells were noted in all affected eyes while 4% had vitreous snow banking and 3% had vitreous snow balls. Most of the patients (52%) received between topical steroid and posterior subtenon injection of Triamcinolone. Visual Acuity was improved in 52% of cases and remained static in 46%.while deteriorated in 2%. Conclusion: Significantly high number of patients with intermediate uveitis has been reported from the central development region, mainly from Dhading, Kathmandu and Nuwakot districts. People in their third decade were found to be commonly involved and Mongloid origin were more commonly affected. Anterior chamber spill over was seen in higher percentage of patients than described in literature. As the patients presented in milder forms, visual acuity improved is 52% of cases with the treatment protocol followedPublication Knowledge, attitude and practices among health care workers on needle-stick injuries(Kathmandu University, 2003) Gurubacharya, DL; KC, Mathura; Karki, DBObjective: This study aimed to assess the knowledge, attitude and practices among health care workers on needle stick injuries. Methods: A 15-item questionnaire was administered to seventy health care workers including nurses and paramedical staffs from different departments of Kathmandu Medical College and Teaching Hospital to measure knowledge, attitude and practices on needle stick injuries. Results: Results showed that 4% and 61% of health care workers, respectively, were unaware of the fact that hepatitis B and hepatitis C can be transmitted by needle-stick injuries. 52 subjects (74%) had a history of needle-stick injuries and only 21% reported the injuries to the hospital authority. Only 23% were in the habit of using gloves for phlebotomy procedures all the time. 79% were of the impression that needle should be recapped after use. Only 66% were aware of Universal Precaution Guidelines. 16 subjects (23%) were negative for HBsAg, Anti-HCV and Anti-HIV and 54 subjects (77%) do not know about their immune status. 42 subjects (60%) had been vaccinated against hepatitis B, while 28 subjects (40%) were not vaccinated against hepatitis B. Only 6 subjects (14%) had been tested for Anti-HBs antibody after hepatitis B vaccination. Conclusion- The survey revealed that knowledge of health care workers about the risk associated with needle-stick injuries and use of preventive measures was inadequate. A standing order procedure (SOP) should be formulated regarding needle-stick injuries in all the health institutions. It should outline precautions to be taken when dealing with blood and body fluids. It should also contain reporting of all needle-stick injuries. Health care workers should be made aware of hazards, preventive measures and post-exposure prophylaxis to needle-stick injuries. A hospital-wide hepatitis immunization programme should also be started.

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 population
