Publication Abnormal Anatomic Variation of Pancreaticobiliary Union in Magnetic Resonance Cholangiopancreatography Department of Radiology and Imaging in a Tertiary Care Centre: A Descriptive Cross-sectional Study(Nepal Medical Association, 2023) Paudel, Sharma; Chaudhary, Bidyanand; Regmi, Pradeep Raj; Kayastha, Prakash; Maharjan, Santosh; Adhikari, GovindaAbstract Introduction: The knowledge of the variations of the abnormal anatomy of pancreaticobiliary union is of great importance for understanding various pathologies of the biliary tract, gall bladder, and pancreas as well as to avoid surgical complications and morbidity which may arise from pancreaticobiliary maljunction. Moreover, it helps in the early diagnosis and preventive treatment of pancreaticobiliary disease. The objective of this study was to find out the prevalence of abnormal anatomic variations of the pancreaticobiliary union in magnetic resonance cholangiopancreatography examinations. Methods: This descriptive cross-sectional study was done in patients referred for Magnetic resonance cholangiopancreatography examinations for various clinical indications from 1 February 2021 to 30 May 2021. Ethical approval was obtained from the Institutional Review Committee [Reference number: 306 (6-11)E 2 077/078]. The variations in the pancreaticobiliary union, length of the common channel, and angle between the common bile duct and major pancreatic duct were obtained from the 1.5T magnetic resonance scanner in 90 patients. The three‑dimensional magnetic resonance cholangiopancreaticography images were visually analyzed and classified into four categories. Convenience sampling method was used. Point estimate and 90% Confidence Interval were calculated. Results: Out of 90 patients, 73 (81.11%) (74.34-87.88, 90% Confidence Interval) patients had abnormal pancreaticobiliary union with pancreaticobiliary type as the most common occurrence seen in 33 (36.67%) patients. Conclusions: The prevalence of abnormal anatomic variation of pancreaticobiliary union was found to be higher than other studies done in similar settings.Publication Compliance with Social Distancing, Facial Mask, Sanitizer/Hand Washing against COVID-19(Institute of Medicine, Tribhuvan University, 2024) Kayastha, Jyoti; Kayastha, Prakash; Nepali, Rabin; Kayastha, UshaAbstract: Introduction: At the end of 2019, a novel coronavirus spread rapidly, resulting in a global pandemic. Many countries have employed various nonpharmaceutical interventions, including social distancing, mask use, and sanitizer/hand hygiene measures (SMS). Previous studies have reported that compliance with these preventive measures varied widely. So, this study was conducted to assess the compliance with social distancing, mask use, and sanitizer/soap use measures in Biratnagar. Methods : This was a descriptive cross-sectional study conducted from September to November 2021 among 310 individuals at a hospital, supermarket, and vegetable market in Biratnagar. Using convenience sampling, mask use, social distancing, and hand hygiene was observed. Individuals not following SMS measures were asked about their reasons for non-compliance. Results : Among 310 individuals, 84.19% used masks, but only 86.97% of them wore them correctly. Surgical masks were used by 93.1%, while 6.9% used cloth masks. Social distancing was followed by 20.96%, and 31.29% used hand sanitizer. Common reasons for noncompliance included discomfort with masks, cost of sanitizer, lack of handwashing facilities, absence of social distancing markings, and poor adherence by others. Conclusion : Compliance of face mask was relatively high, while compliance with social distancing and sanitizer use was low highlighting the need for improved public awareness, better infrastructure, and stricter enforcement. In low-resource settings like Nepal, the continued promotion of SMS measures is essential for managing current health threats and preventing future outbreaks of respiratory illnesses.Publication Computed Tomography Chest Findings in COVID-19 Patients(Nepal Health Research Council, 2022) Tamang, Ongden Yonjen; Paudel, Sharma; Kayastha, Prakash; Maharjan, Santosh; Adhikari, Govinda; Upadhyaya, Rudra Prasad; Dawadi, Kapil; Pradhan, Prajina; Rehman, Tanveer; Malla, Saurav KrishnaAbstract Background:COVID-19 which has caused significant morbidity and mortality around the world has been declared by the World Health Organization to be a global health emergency. Our objective was to find out the lung parenchymal patterns commonly evident in high resolution Computed Tomography in patients with COVID-19 pneumonia. Methods: A retrospective cross-sectional study was conducted at a tertiary multi-specialty hospital in Kathmandu, Nepal. With ethical clearance from the institutional review board, a total of 235 patients with positive reverse transcriptase polymerase chain reaction for COVID-19 and having respiratory symptoms were included in the study. High Resolution Computed Tomography images of chest were retrieved from picture archiving and communication systems retrospectively and studied for the findings commonly attributed to COVID-19 pneumonia. The data was then analyzed using Stata version 14 (Stata Corp, College Station, TX, USA). Descriptive statistics were presented as mean and median while chi-square test was used to assess the association between socio-demographic characteristics and CT severity indices. Results: Out of 235 patients, 174 (74.0%) were males and 61(26%) were females with a mean age of 54.8±14.5 years. The most commonly encountered pattern of pulmonary changes was bilateral involvement in 222 (94.5%) patients followed by ground-glass opacities in 218 (92.8%) patients and peripheral predominance of ground-glass opacities in 211 (89.8%) patients. Conclusions: Chest Computed Tomography abnormalities are common in COVID-19 positive patients with respiratory symptoms. These findings can guide in the assessment of the severity of the disease as well as patient management.

Common complications of lung biopsy include pneumothorax, parenchymal haemorrhage and haemoptysis. The study aimed to determine the prevalence of ultrasound-guided biopsy among patients with lung lesions undergoing procedures in interventional radiology of a tertiary care centre. Methods: A descriptive cross-sectional study was performed in the Department of Radiology and Imaging from 1 August 2018 to 30 September 2019 after obtaining ethical approval from the Institutional Review Committee. USG-guided biopsy of peripheral lung lesions was performed with an 18 gauge semiautomatic biopsy instrument and a 17 gauge coaxial needle. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 188 biopsy of lung lesions, ultrasound-guided biopsies were performed in 28 (14.89%) (9.80-19.98, 95% Confidence Interval). Conclusions: The prevalence of ultrasound guided biopsy among lung lesions is lower than other studies done in similar settings.Publication Variation in the Branches of Arch of Aorta in Patients Undergoing Contrast Enhanced Multidetector Computed Tomography in a Tertiary Centre, Nepal(Nepal Medical Association, 2024) Kayastha, Prakash; Paudel, Sharma; Bista, Nikesh; Adhikari, Binaya; Katwal, ShailendraAbstract Introduction: Variations in the branching pattern of the Arch of Aorta (AoA) are common in patients undergoing contrast-enhanced Multidetector Computed Tomography, the identification of which is crucial in managing patients undergoing cardiovascular/neck surgeries and interventions. Methods: This prospective cross-sectional study involved 513 patients who were sent to the Department of Radiology for evaluation of various pathologies of chest and neck between August 2018 and July 2019. After approval from the Institutional Review Committee {Reference No: 11(6-11) E2/075/076}, contrast-enhanced computed tomography images were evaluated with variations in branches of the left-sided arch of the aorta and symptoms associated. Results: Variations in branches of the arch of aorta were seen in 69 (13.45%; 95% CI: 10.60%-16.71%) of cases, left common carotid artery and brachiocephalic trunk having common origin or common trunk was 51(9.94%). The mean age was 52.4±20 years (Range 3 months to 92 years) with male to female ratio of 1.3:1. Conclusions: Contrast-enhanced computed tomography is the modality of choice for the detection of the variations in branches of AoA, recognition of which is crucial in vascular intervention and surgical procedures to reduce the postoperative morbidity and mortality of the patients.
