Publication Alveolar Bone Biology in Extrusion Splint Technique(Kathmandu University, 2012) Sharma, P; Shankar, TPABSTRACT The moment after the tooth avulsion, blood supply to the pulp is interrupted and the periodontal ligament cells are exposed to injury from the external environment. Complete healing is possible if the tooth can be immediately replanted and favorable environment is created .A case of report of intruded and mobile upper left central incisor due to Road Traffic Accident of a twenty-two-year-old patient is presented here. In which, intentional extrusion traumatized tooth and then flexible acrylic wire splinting was done to stabilize it. Previously there was no periapical bone support but with nine months maintenance follow up bone has shown a significant improvement towards healing. KEY WORDS Traumatized tooth, extrusion, intrusion splint, acrylic wire splintPublication An ultrasonographic evaluation of solitary muscular and soft tissue cysticercosis(Kathmandu University, 2010) Sharma, P; Neupane, S; Shrestha, M; Dwivedi, R; Paudel, KAbstract Background: Cysticercosis in humans is infection with the larval form (cysticercus cellulosae) of the pork tapeworm T. solium. Encystment of larvae can occur in almost any tissue. The location of cysts in order of frequency is the central nervous system, subcutaneous tissue and striated muscle, vitreous humour of the eye and, rarely, other tissues. High resolution ultrasound can be used in the diagnosis of muscular and soft tissue cysticercosis. Objective: The aim of this study is to evaluate the ultrasonographic findings in cases of muscular and soft tissue cysticercosis. Materials and methods: It was a retrospective review of the cases of muscular and soft tissue cysticercosis which were diagnosed by ultrasound during June 2007 to May 2009 in the department of Radiology and Imaging, Nepalgunj Medical College Teaching Hospital. A total of six patients were evaluated. Result: There were four males and two females. Age of the patient ranged from 18 to 50 years. All of the patients presented with a swelling with pain in five of them. There was a wide variation in the location of the cysts. In all cases ultrasound revealed a cystic lesion with an echogenic eccentric pedunculated nodule attached to the wall. The mean diameter of the cyst was 6mm. Smooth wall was present in five cases whereas one of the cysts revealed irregular wall. Pericystic inflammatory changes were seen in the adjacent muscles. Conclusion: Ultrasound is a safe and non-invasive method that can be used in the diagnosis of muscular and soft tissue cysticercosis. Key words: Muscular and soft tissue cysticercosis, ultrasound.Publication Biomarkers of Electroconvulsive Therapy (ECT) Response in Treatment-resistant Schizophrenia (TRS)(Kathmandu University, 2024) Sharma, P; Sharma, PABSTRACT Electroconvulsive therapy (ECT) is a well-established treatment option for individuals with treatment-resistant schizophrenia (TRS). However, predicting treatment response and identifying potential biomarkers to guide electroconvulsive therapy interventions in treatment-resistant schizophrenia remains a challenge. This review paper aims to explore the current literature on clinical biomarkers associated with electroconvulsive therapy in treatment-resistant schizophrenia. We discuss various potential biomarkers, including clinical, neuroimaging findings, EEG markers, and genetic markers, that have shown promise in predicting electroconvulsive therapy response and understanding the underlying mechanism of action. Additionally, we highlight the limitations and future directions for research in this field.

Understanding the clinical and endoscopic findings in patients presenting with upper gastrointestinal bleeding is essential for accurate diagnosis and effective treatment. Objective To investigate the age and sex composition, clinical presentations, and endoscopic findings of patients with upper gastrointestinal bleeding at a tertiary care hospital. Method A total of 561 patients with upper gastrointestinal bleeding were included in the study. Data on age, sex, and clinical presentation were collected for each patient. Endoscopic findings were recorded, and the relative frequency of various upper gastrointestinal lesions was analyzed. Result The age distribution of patients revealed that 40.82% were between 15 and 45 years, 32.98% were aged 46 to 65 years, and 26.20% were above 65 years. Among the patients, 73.08% were male and 26.92% were female. Hematemesis was observed in 248 cases, while melena was present in 136 cases, and both were present in 171 cases. Recent onset anemia with positive occult blood was reported in 6 patients. The most common endoscopic finding was varices (39.39%), followed by ulcers (15.51%). Mallory Weiss tear was noted in 5.53% of cases. Conclusion According to our findings, varices are the most common endoscopic finding in individuals with upper gastrointestinal bleeding rather than peptic ulcer disease. The considerable increase in varices emphasizes the critical importance of early identification and care in high-risk individuals, as well as contributing to a better understanding of upper gastrointestinal bleeding.

It is associated with various adverse outcomes. Despite its enormous prognostic significance it tends to be underdiagnosed. There is a dearth of studies on risk factors of delirium in our setting. Objectives The main objectives of this study was to find out the prevalence, rate of non recognition and risk factors associated with delirium in hospitalized critically ill patients. Methods A hospital based cross-sectional study was carried out. Data was collected using a predesigned semi-structured proforma and Intensive care delirium screening checklist was used to screen for delirium in patients admitted in various wards of Manipal teaching hospital, Pokhara, Nepal. Results Ninety five cases were included in the analysis. The mean age of study group was 58.9 ± 19.1 years. Delirium was present in 15/95 cases and it was not recognized by treating physician in about one third of cases. Odds ratio (OR) was statistically significantly increased in patients with history of stroke (OR=4.484 95% CI=1.0896;18.459), alcohol use (OR=10.792 95% CI=2.906;40.072), smoking (OR= 4.836 95% CI= 1.411;16.576), use of restraint (OR=17.143 95% CI=4.401;66.766), nasogastric tube placement (OR= 7.731 95% CI=2.348;25.452) and use of Foley’s catheter (OR=12.000 95% CI= 3.072;46.877). Conclusion About 16% of critically ill patients were found to be delirious. In about one third of the cases delirium was not recognized. Both patient related and iatrogenic factors may increase the risk of delirium in hospitalized critically ill patients.

Mental stress is possibly the most important known predisposing factor for primary dysmenorrhea. Objective This study aims to assess the relationship between stress and dysmenorrhea amongst the Nepalese medical students. Method This is cross-sectional descriptive study, conducted from 1st Dec. 2012 to 31st Jan. 2013. The study was conducted in Kathmandu University School of Medical Sciences. A total of 184 participants consented for this study and each one was given a questionnaire to complete. This study included only unmarried nulliparous, healthy (all through first to final years) female medical students, in age group of 16 to 24 years. Result The mean age of the participants was 19.43(±3.9) years. Among them, 67% of the participants experienced dysmenorrhea. Of them, 85% experienced increase in frequency and severity of dysmenorrhea after joining medical college. Similarly, 65% of participants considered medical education to be stressful. Of participants experiencing dysmenorrhea, 29.45% missed classes and 17.39% participants had positive family history of dysmenorrhea in first and second degree relatives. Conclusion The present study indicated a positive relationship between psychological stress and dysmenorrhea. Dysmenorrhea is the leading cause of recurrent short-term school absence in young ladies; this issue certainly needs to be addressed.

In Nepal, there are limited insights on existing studies regarding technical, financial, human resources, ethical and privacy related challenges of AI in the health sector, and this is the gap our study aims to fulfill. Our study aimed to synthesize empirical studies on the challenges and opportunities of using AI by conducting a systematic literature review. We retained 33 articles published between 2010 and 2023 in the PubMed, Google Scholar, Science Direct and CIHANIL databases. Most of the articles reviewed indicated that there are several challenges related to AI administration into healthcare in Nepal, however there are also an opportunity associated with this relating to cost-effectiveness of the services, increased access to specialized health services, teamwork and decision makings, diagnosis and patient monitoring, and telemedicine. However, findings show that use of AI in healthcare additionally faces several challenges including technical, geographical, economic, ethical and privacy, and human resource related challenges. Our findings recommend that AI has the potential to transform healthcare and while addressing these challenges is important to fully utilize its services especially in rural Nepal.

It is associated with 10 times to 17 times increase in mortality and markedly increase morbidity. Objective To find out the frequency of Low cardiac output syndrome following on pump coronary artery bypass grafting surgery, to determine the association of Low cardiac output syndrome with degree of pre-operative left ventricular dysfunction and to compare in hospital outcomes of coronary bypass surgery with and without low cardiac output syndrome. Method This prospective, descriptive study enrolled 200 patients who underwent on pump coronary artery bypass grafting surgery using antegrade St Thomas blood cardioplegia. Pre-operatively grouped into two groups consisting Group A of 100 patients with pre-operative left ventricular ejection fraction (LVEF) ≥ 40% and group B of 100 patients with pre-operative left ventricular ejection fraction (LVEF) < 40%. Post-operatively frequency of low cardiac output syndrome was compared between the groups and in-hospital outcomes were studied. Result The mean age of the patients in the study was 53.50±7.57 years. Male to female ratio was 1.8:1. Results showed overall frequency of low cardiac output syndrome was 21.5%. The frequency of LCOS was 15 vs 28% (p - 0.038) in patients with pre- operative LV EF ≥ 40% and < 40% respectively. The outcomes of coronary artery bypass grafting surgery were stroke (3.82 vs. 30.23%, p - 0.001), acute kidney injury (5.09 vs. 23.25%, p - 0.001), respiratory failure (6.36 vs. 34.88%, p - 0.001), ICU stay days (4.75 ± 1.28 vs. 7.44 ± 4.66, p - 0.018), hospital stay days (9.56 ± 2.40 vs. 15.22 ± 3.89, p - 0.001) and mortality (4.45 vs. 32.55%, p - 0.001) in patients without and with low cardiac output syndrome respectively. Conclusion The frequency of low cardiac output syndrome following coronary artery bypass surgery is 21.5%. Left ventricular dysfunction pre-operatively is associated with high frequency of low cardiac output syndrome following surgery. There is significantly poor outcome of coronary artery bypass surgery with low cardiac output syndrome in terms of stroke, respiratory failure, acute kidney injury, mortality and significant ICU stay, hospital stay in compare to patients without low cardiac output syndrome. KEY WORDS Coronary artery bypass, Low cardiac output, Ventricular dysfunction, Coronary artery diseasePublication Heart rate variability: Response to graded head up tilt in healthy men(Kathmandu University, 2009) Sharma, P; Paudel, BH; Singh, PN; Limbu, PAbstract Background: Heart rate variability is actually a misnomer for R to R variability in cardiac cycle. Variation in successive cycle length is called the heart rate variability (HRV). Head-up tilt is a model of studying cardiovascular haemodynamics, which reflects in heart rate variability (HRV). Objectives: To study the effect of 10° and 70° head-up tilt on HRV. Materials and methods: The study was done in the Department of Physiology using graded head up tilt (passive orthostatism). HRV measurement was done at 10° and 70° tilt and compared with supine using standardised methods on 30 consenting healthy males (age 25.37±3.89 years). The HRV variables across postures were compared by ANOVA and Bonferroni test. Results: The heart rate increased at 70° compared to 10° and supine (70.48±8.17 Vs 70.22±8.67 and 88.51±12.84 bpm, p<0.001). The 70° tilt decreased vagal HRV indicators compared to 10° and supine: SDNN (31.13±8.12 Vs 38.07±11.29 and 38.13±10.89 ms, p<0.05), RMSSD (20.06 ±8.47 Vs 34.23±14.22 and 36.16±12.22 ms, p<0.001), NN50 count (13.03±20.58 Vs 45.07±44.44 and 55.27±44.10, p<0.01), pNN50 (3.28±6.08 Vs 14.06±15.65 and 16.65±14.23, p<0.01), HF power (197.20±143.76 Vs 218.17±155.85 and 216.87±150.98 Hz, p<0.05), HFnu unit (24.28±14.16 Vs 45.48±16.34 and 47.67±19.89, p<0.001). The 70° tilt increased LF power% (197.20±143.76 Vs 218.17±155.85 and 216.87±150.98, p<0.001). LFnu unit (75.72±14.76 Vs 54.52±16.34 and 52.32±19.89, p<0.001), LF: HF (4.96±4.08 Vs 1.53±1.138 and 1.69±1.67, p<0.001) compared to 10° and supine. Conclusion: At 70° tilt, HRV measures, reflecting vagal contribution to cardiac-cycle length, decreased with reciprocal increase in sympathetic activity compared to 10° or supine leading to increase in sympathetic predominance. A 10° tilt, which is almost equivalent to lying down with pillow, did not change HRV from supine.

However, it is important to identify and treat postpartum depression because it can have grave consequences for both the mother and her children. Objective To determine the screening prevalence and risk factors of postpartum depression, among women who deliver at university hospital Nepal. Method This is a cross-sectional study investigating the relationship between postpartum depression and various factors. A total of 100 postpartum women who presented to a Dhulikhel hospital for delivery were interviewed on days 2-3 after delivery. The mothers were administered Edinburgh Postnatal Depression Scale (EPDS) as well as a proforma that included questions about the known risk factors (sociodemographic and sociocultural factors, and mother-related, pregnancy-related, and child related factors). Result The overall screening prevalence of depressive symptoms in the postnatal period (defined as EPDS=>13) was 29 %( 95% CI 20.1%-37.8%). On univariate analysis (chi square test), postpartum depression was significantly associated with pregnancy complications (p<0.01), infant’s health problems (p <0.001) and vaginal delivery (p <0.05). Conclusion Postpartum depression is common among Nepalese women and can be detected early in the postpartum periods; and many psychosocial factors like pregnancy complications, infant’s health problems and vaginal delivery are associated with it. It is recommended that mothers with high risk should be routinely screened for postpartum depression. KEY WORDS Developing countries, hospital delivery, infant welfare, prevalence, risk factors
