Publication A case of left atrial myxoma: Anaesthetic management(Kathmandu University, 2006) Pradhan, B; Acharya, SPLeft Atrial Myxomas are notorious for their varied presentations. We describe one such case which initially presented with hemiparesis and seizures and was diagnosed as cerebral infarction and treated accordingly and decompression craniotomy with hinge flap was done for raised ICP and impending brain herniation. The main cause was a left atrial myxoma, which was diagnosed only in follow up. The myxoma has embolised to give rise to cerebral infarction. The LA myxoma was then successfully operated under general anaesthesia and Cardiopulmonary bypass (CPB). Key words: Hemiparesis, Cerebral infarction, Left Atrial (LA) MyxomaPublication Application of “the Sequential Organ Failure Assessment (SOFA) score” in predicting outcome in ICU patients with SIRS(Kathmandu University, 2007) Acharya, SP; Pradhan, B; Marhatta, MNAbst ract Background: Various scoring systems have been developed to prioritize patient admission and management in ICU. The objective of this prospective, observational cohort study was to evaluate application of one such system, the Sequential Organ Failure Assessment (SOFA) Score in predicting outcome in ICU patients with SIRS. Patients and Methods: Fifty patients admitted to a six bed multidisciplinary ICU with SIRS were consecutively enrolled in the study and SOFA scores were calculated at zero hour, after 48 hrs, and after 96 hrs and patients followed till discharge from hospital. Results: When compared to outcome, the non survivors had high initial, mean and highest SOFA scores as compared to survivors. (p value = 0.002, <0.001, <0.001 respectively). Delta SOFA was not significantly associated with outcome. (p value= 0.117). The initial SOFA score > 11 predicted a mortality of 90%. (OR 23.72, 95%CI2.68- 209.78, p=0.004). Similarly, mean SOFA score of > 7 predicted a mortality of 73.9% (OR 22.7, 95%CI 5.0 – 103.5, p<0.001) and high SOFA score > 11 predicted a mortality of 87.5% (OR 32.66, 95%CI 5.82-183.179, p< 0.001). Area under receiver operating characteristic (ROC) curve for mean SOFA was 0.825, for high SOFA was 0.817 and for initial SOFA was 0.708. Thus mean, high and initial SOFA scores were helpful in predicting between the survivors and the non survivors. Conclusion: The SOFA scoring system is useful in predicting outcomes in ICU and thus help in proper utilization of ICU resources.

It is a complex issue that has been studied widely and continues to be of great interest among community health workers. This paper presents a brief review of various aspects of community participation. It then illustrates how it is practiced at Duwakot Community Hospital, Kathmandu Medical College, Duwakot, Bhaktapur, Nepal in collaboration with the local community. Key words: Primary Health Care, Community ParticipationPublication Correlation of PAP smear findings with clinical findings and cervical biopsy(Kathmandu University, 2007) Pradhan, B; Pradhan, SB; Mital, VPAbstract Objectives: Carcinoma of the cervix is the most common cause of the death in Nepal. Cervical carcinoma does not develop suddenly from normal epithelium but is presented by a spectrum of intraepithelial neoplastic changes that are precancerous lesion and were termed as cervical intraepithelial neoplasia (CIN). Cervical cytological screening is designed to detect over 90% of cytological abnormalities. It has also been established that most cervical cancers can be diagnosed at the preinvasive stage with adequate and repetitive cytological screening. Keeping in view of the importance of carcinoma and the precancerous lesion (CIN) of cervix, study of different methods for the early detection of abnormalities in cervix, correlation with the clinical findings and comparison between the techniques was carried out. Material and methods: Patients with suspicious cervix attending Gynaecology OPD of TUTH and Western regional hospital (Pokhara) who have undergone for pap smear cytology test along with biopsy were selected. Detail history with clinical examination was performed and the findings were correlated. Results and conclusion: Unhealthy cervix with discharge was found to be common even in chronic cervicitis however bleeding and tenderness were associated with more advanced lesions. Pap smear test was found to be equally sensitive to histopathological examination for the early detection of different cervical lesions. However, it is advised to perform biopsy if any abnormalities are detected in pap smear for correlation and confirmation.

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.

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.

It is commonly applied in all the paediatric patients undergoing the above mentioned surgery, as the goal of balanced anaesthesia is not only limited to intraoperative period but also good analgesia in post operative period. Many drugs like morphine, Pethidine, Neostigmine etc have been used as analgesic agent via the caudal route but not without their side effects. So Midazolam was used as an alternative drug as it may not be associated with the side effects encountered with the other drugs. Aims and objectives: The objective of the study was to see the analgesic efficacy of caudal administration of Midazolam with comparison to Bupivacaine for post operative analgesia, and to observe for side effects if any. Materials and methods: This was a single blinded prospective observational study in children of age 1 to 6 years of ASA grade I undergoing elective hernia or hydrocoele surgery. The patients were allocated randomly into two groups (n=25) to receive caudal injection of either 0.25% Bupivacaine 1ml/kg (group A) or Midazolam 50μg/kg with normal saline 1ml/kg (group B). In the post operative period heart rate, blood pressure, pain score, recovery to first analgesic time, total number of analgesics required in 24 hours and side effects if any were noted and analysed. Results: There were no significant differences in quality of pain relief, postoperative behaviour or analgesic requirements between the Midazolam group and the Bupivacaine group. Recovery to first analgesic time though was longer in the Bupivacaine group (9.65 hr) than Midazolam group (7.32 hr); it was statistically not significant (P= 0.9). Any of the side effects such as motor weakness, urinary retention, and respiratory depression were not observed in both the groups. However in both the groups, few of the patients had post operative vomiting. Conclusion: We conclude that caudal Midazolam in a dose of 50μg/kg provides equivalent analgesia to Bupivacaine 0.25%, when administered in a volume of 1ml/kg for children undergoing unilateral inguinal herniotomy for hernia or high ligation of processus vaginalis for hydrocoele.

Potential infectious risks include the spread of infectious diseases and microbial resistance from health-care establishments into the environment and thereby posing risks of getting infections and antibiotic resistance in the communities. Objectives: The objectives of this study were to assess the bacterial load of healthcare liquid waste generated in central hospitals and to explore the antimicrobial resistance pattern of these bacterial isolates. Materials and methods: A descriptive study was carried out in 10 conveniently selected central hospitals of Nepal during the period of May to December 2008. Effluent specimens from each hospital were subjected to total viable count studies by spread plate method in nutrient agar plate and incubated for 24 hours at 370C using standard laboratory protocol. Similarly, all the specimens were cultured in Mac Conkey Agar media supplemented with 30 μg/ml of Chloramphenicol and 20 μg/ml of Gentamycin for the enumeration of multiple drug resistant (MDR) bacteria, which were further subjected to in-vitro antibiotic susceptibility test by modified Kirby Bauer disc diffusion technique for resistance patterns. Results: Total viable counts of hospital effluents significantly exceeded the standard heterotrophic plate count (p=0.000). Similarly, the numbers of multiple drug resistant bacteria were alarmingly high in three (more than 30% in 2 and 50% in 1) hospitals of this study. Drug resistant hospital effluent isolates showed simultaneous resistance for most of the antibiotics including Penicillin, Cephalosporin, Cotrimoxazole, Gentamycin and Quinolones. Conclusion: Healthcare liquid wastes were laden with MDR bacteria and seemed to pose a huge public health threat in the transfer of such resistance to the bacterial pathogens causing community acquired infections, thereby limiting our antibiotic pool.

The importance of extra pulmonary tuberculosis (EPTB) among all forms of tuberculosis has not yet been ascertained in developing countries Objective: To identify and perform phenotypic characterization of clinically important mycobacterium isolates from extra-pulmonary sites along with drug susceptibility testing. Materials and methods: A total of 513 specimens from patients of (EPTB) with varied presentation were studied. Speciation and characterization of isolates were done on the basis of growth and biochemical characteristics. Drug susceptibility testing for mycobacterium isolates was done by proportion method. Results: Fifty four patients clinically suspected to have extra-pulmonary tuberculosis were culture positive for mycobacteria. On characterization 48 of the 54 isolates were identified as M. tuberculosis, 4 as M. bovis and 2 were M. avium/ intracelulare. Drug susceptibility testing was done for the both M. tuberculosis as well as M. bovis. In single drug resistance, Streptomycin was highest followed by Isoniazid, Ethambutol and Refampicin. Multi drug resistance (MDR) was found in 6 isolates and it was observed only in group I cases. Conclusion: EPTB accounts for 10-15 percent of all cases of tuberculosis. Mycobacterium was present in 10.5 percent samples. 48 isolates out of 54 samples were found to be M. tuberculosis. The maximum numbers of M. tuberculosis were isolated from lymph node aspiration.
