(Kathmandu University, 2022) Karmacharya, RM; Singh, AK; Vaidya, S; Tuladhar, SM; Devbhandari, M; Lama, B; Kharel, BB; Basnet, S
ABSTRACT Background Lung cancer is one of the leading cause of cancer related death. Most common histopathology of lung cancer is non-small cell carcinoma of which adenocarcinoma is the most common. There are limited number of studies done in Nepal to know different aspects of lung cancer. Objective To know demographic parameters of patients diagnosed as lung cancer in a university hospital. The study also aims to know the different histopathological diagnosis of lung cancer. Method All the patients presenting to outpatient department (Cardio Thoracic and Vascular unit) of Dhulikhel Hospital, if are diagnosed as cancer of lung/bronchus will be included in the study. The duration of the study was January 2017 to December 2021. The details on age, gender, presenting symptoms, histopathology of lung cancer, operability will be included in database and will be analyzed. Result There were total of 127 patients diagnosed as lung cancer. Male:female ratio was 1.7:1. Overall mean age was 63.23 years (SD 13.5 years, Range 19-89 years). Non small cell carcinoma was the most common type of lung cancer with 83.7%. In non small cell carcinoma, most common type was Squamous cell carcinoma followed by undifferentiated and Adenocarcinoma. Only five (3.93%) cases were in operable stage. Conclusion Despite the fact that lung cancer is one of the most common cancer, patients usually present late and moslty are not in operable stage. This study shows that squamous cell carcinoma is the most common histopathology in lung cancer cases. KEY WORDS Lung Cancer, Smoker, Thoracotomy
C-ARM Guided Angiogram/Angioplasty for Selected Failed Arterio Venous Fistula. A Report of a Procedure at University Hospital of Nepal
(Kathmandu University, 2021) Vaidya, S; Karmacharya, RM; Singh, AK; Vaidya, PR; Malinowski, M; Dhakal, A
ABSTRACT End Stage Renal Disease is a last stage of Chronic Kidney Disease which is characterized by Glomerular Filtration rate of less than 15 ml/min/1.73 m2. Hemodialysis is the most commonly used modality for treatment of Chronic Kidney disease. Among the access for hemodialysis arteriovenous fistula is the most common modality. However most common problems of fistula are significant stenosis of more than 50% which is characterized by limb swelling, pigmentation, tortuous veins, and difficulty maintaining flow during dialysis from AV fistula. These can be managed either by minimal intervention or with surgical intervention. Very few hospitals in Nepal and other countries have an angiographic suite to perform minimal intervention include angiogram with angioplasty. So in this case we try to address the use of C-Arm to perform angiogram or fistulogram and even angioplasty for the management of significant stenosis or complications of arteriovenous fistula. KEY WORDS Angiogram/Angioplasty, Arterio venous fistula, C-arm

ABSTRACT Background Kidney biopsy is an important diagnostic tool in Nephrology. As of now, we don’t have a central kidney biopsy registry in our country and there are many studies showing heterogeneous patterns of pathologies observed in the country. We thought of looking on the clinico-pathological profile of kidney biopsy patients prevailing in our centre. Objective This study was carried out with an objective to know the clinico-pathological profile of kidney biopsy patients prevailing in our centre. Method This was a hospital based, prospective, observational study carried out in a tertiary teaching hospital of Chitwan over a period of 3 years from May 2016 to April 2019. All the consecutive kidney biopsy patients were included in the study. The indication of kidney biopsies were the standard indication based on clinical presentation and investigations. The patient`s demographic profile, indication of kidney biopsy and histological patterns were studied and analysed using appropriate statistical tools. Result A total of 210 kidney biopsies were analysed over a period of three years, that makes around 5-6 biopsies per month. The mean age of the patient was 35.7 ± 14.9 years. Male were 106 (50.5) and females were 104 (49.5) with male to female ratio of 1.01. The average number of glomeruli was 23.4 ± 11.0. The commonest indication of kidney biopsy and histological pattern were nephrotic syndrome 56 (26.7) and IgA nephropathy 51 (24.2) respectively. Among nephrotic syndrome group, the commonest histological pattern was minimal change disease 21 (37.5). Non-diabetic kidney diseases in diabetes were seen in eight (53.4) diabetic patients making it a significant problem in diabetes and the commonest histological pattern in them were minimal change disease and idiopathic cresentic glomerulonephritis two (13.3) each. Conclusion The commonest indication and histological pattern of the kidney biopsy were nephrotic syndrome 56 (26.7), and IgA Nephropathy 51 (24.2) respectively.

ABSTRACT Background Maintenance hemodialysis is a popular treatment modality of renal replacement therapy for end stage renal disease patients; however their mortality seemed to be rising in our centre. There were no previous studies regarding the clinicodemographic profile and outcome of maintenance hemodialysis patients from this region. Objective This study was carried out with an objective to know the clinicodemographic profile and outcome of maintenance hemodialysis patients in our centre. Method This study was a hospital based prospective observational study carried out over a period of three year, from May 2016 to April 2019, in the hemodialysis unit of the department of nephrology. All the consecutive end stage renal disease patients on maintenance hemodialysis were included in the study. The patient’s demographic profile and outcome were studied and analysed using appropriate statistical tools. Result A total of 156 patients were enrolled in the study. Males were 96(61.5%) and females were 60(38.5%). The mean age of the patient was 52.2±15.6 years. The commonest causes of end stage renal disease and reasons for admission were Type 2 diabetes mellitus 68(43.6%) and volume overload with heart failure 101(64.7%) respectively. At the end of three years, 39(25%) were expired, 14(8.9%) were transferred to other centre and four (2.6%) underwent kidney transplantation. The average duration of hemodialysis was 20.3± 17.5 months. Majority of the patients 154(98.7%) had repeat admission ranging from 1 time 21(13.5%) to 10 times two (1.3%). There was a significant association between age ≥ 40 years and diabetes with mortality (p value < 0.003 and < 0.028 respectively). Conclusion The commonest cause of end stage renal disease and the reason of admission were Type 2 diabetes mellitus 68 (43.6%) and volume overload with heart failure 101 (64.7%) respectively. The overall mortality was 39 (25%) and the commonest cause of mortality was sepsis/health care associated pneumonia 30 (76.9%). There was significant association between age ≥ 40 years and diabetes with mortality (p value < 0.003 and < 0.028 respectively).

(Kathmandu University, 2022) Vaidya, S; Karmacharya, RM; Shrestha, B; Adhikari, MM; Sharma, R; Khadka, S; Bhandar, N; Hada, G
ABSTRACT Background Pneumothorax is a condition in which air or other gas is present in the pleural cavity. Mainstay of management of pneumothorax is to remove the air from the pleural space usually done by chest tube insertion. There is still uncertainty whether minimal invasive management with pigtail catheter is sufficient for the management of pneumothorax. Objective To find the effectiveness, safety, tolerability, efficacy of pigtail catheters and large bore chest tubes. Method Prospective comparative study was done in Dhulikhel Hospital between August 2019 till August 2021. Chest tube insertion used to be the only available treatment modality till December 2020 (15 months). Following January 2021 after obtaining ethical clearance for use of pigtail insertion for pneumothorax, this treatment modality was done (8 months). Result Among 76 patients, 52(68.4%) underwent a large bore chest tube and 24 (34.6%) pigtail catheter patients. Mean age of the patients was 48 years (SD 18.01). Duration of hospital stay and length of hospital stay was more in large bore catheters and less in pigtail catheters. Eight hours post tube placement of the expansion of the lungs was present in pigtail and was statistically significant. Pain killer used in pigtail catheters was limited to Non-steroidal anti-inflammatory drugs, for large bore catheter opioids were added and were statistically significant. Conclusion Pigtail catheter is nearly effective as compared to traditional wide bore catheters. KEY WORDS Large bore chest tube, Painkillers, Pigtail, Pleural space, Pneumothorax

(Kathmandu University, 2018) Maharjan, BR; Bhandary, S; Upadhyay, S; Ghimire, S; Shrestha, I; Joshi, M; Vaidya, S; Pradhan, P
ABSTRACT Background Integrated curriculum enhances students’ learning and the retention of knowledge. At Patan Academy of Health Sciences, integrated organ system based curriculum is used with Problem Based Learning as the principle teaching learning method to foster students’ learning. In addition, other approaches of integration were under taken such as integrated assessment; logical arrangement teaching learning methods (lectures and practicals); joint effort of faculty in curriculum planning and delivery; conducive environment to foster hidden curriculum. This study describes the perception of faculty and students on integration characteristics of Basic Science curriculum. Objective To measure the integration characteristics of Basic Science Curriculum. Method Tool was developed to measure integration characteristics of Basic Science Curriculum and ensure whether such planned integration has been achieved. Mixed method was used to measure the perception of the integration characteristics i) quantitatively by questionnaire survey to faculty and students ii) qualitatively by in-depth interview of students. Result Both faculty and students perceived that all the blocks in Basic Science was well integrated in the quantitative questionnaire survey. But, in the in-depth interview, students perceived integration of curriculum in organ system blocks were better integrated compared to Principle of Human Biology blocks where fundamentals of basic science disciplines were delivered. Students reflected that Problem Based Learning not only integrated Basic Science disciplines but also with clinical sciences and the social context. But, students perceived that Community Health Sciences curriculum was not so well integrated with Basic Science subjects. Conclusion Overall, this study showed that planned integration in Basic Science curriculum was successfully executed during curriculum implementation.

(Kathmandu University, 2024) Karmacharya, RM; Maharjan, S; Vaidya, S; Bhatt, S; Sharma, S; Timalsina, G; Kunwar, K; Joshi, HN
ABSTRACT Background Diabetic foot ulcers (DFUs) are a common complication in diabetic patients especially in those with peripheral arterial disease (PAD). However, it can be prevented if its risk factors can be identified and adjusted. Objective To investigate the frequency of diabetic foot ulcers and their associated risk factors in diabetic patients with peripheral artery disease. Method Diabetic patients under medication with known peripheral arterial disease diagnosed with Doppler ultrasonography were recruited from the outpatient department of the cardiothoracic and vascular unit, at Dhulikhel Hospital. The patients were interviewed about their demographic details, presenting clinical symptoms, and the risk factors such as smoking, hypertension, cardiovascular diseases, duration of diabetes, and hyperlipidemia. Also, the patients were assessed for any ulcers in their feet. Descriptive statistics and chi-square tests were used to analyze the data. Result The analysis demonstrated diabetic foot ulcers in 24.1% of the total 54 diabetic patients with peripheral arterial disease. The risk factors such as smoking (24.1%), increasing age (68.5%), hypertension (31.5%), and duration of diabetes (72.2%) were found in the majority of the patients. Out of these risk factors, smoking (Odds ratio: 6.81) and increasing age (Odds ratio: 0.28) were significantly associated with diabetic foot ulcers. (p < 0.05) Conclusion Diabetic foot ulcers affected about a quarter of diabetic patients with peripheral arterial disease and were found to be associated with increasing age and smoking.

(Kathmandu University, 2025) Karmacharya, RM; Vaidya, S; Bhatt, S; Guragai, M; Sharma, S; Bhandari, S; Shrestha, M; Shah, B; Yadav, B
ABSTRACT Background Chest wall tumors are rare thoracic tumor which can be either primary or metastatic. Conventional radiography is the first line of investigation followed by further imaging like computed tomography or magnetic resonance imaging. When indicated preoperative biopsy by fine-needle aspiration need to be done. Small chest wall tumor can be surgically treated by excision and primary repair. Bigger chest wall tumor is treated by excision and chest wall reconstruction. Objective To know the features of chest wall tumor, symptoms, histopathological findings, surgical procedures performed and outcome following the surgery. Method This is the retrospective study that included chest wall tumor subjected for excision and repair during January 2018 till December 2023 in Thoracic surgical unit of Dhulikhel Hospital. Variables such as presenting complaints, size and extent of tumor, type of surgery, outcome of the surgery, hospital stay, neoadjuvant chemotherapy and post excision chemo or radiotherapy and recurrence of the tumor were included. When primary repair is not possible following wide excision, reconstruction using double prolene sandwich mesh was done. Result There were 38 cases of chest wall tumor. Mean age of the patient was 42 years (SD 15.25 years, range 20 - 68 years). Of them, 22 patients were female (57.9%) and 16 patients were male (42.1%). Chest pain was the most common symptoms (84.2%) followed by lesion in chest (81.6%). Average size of the tumor was 14.8 ± 3.6 cm (Range 5 cm to 25 cm). Most common histopathological finding was neurofibroma (31.6%) filled by schwannoma (15.8%). All the patients underwent wide local excision. In terms of repair, primary repair was possible in 68.4% while in 31.6% patients repair using double prolene and bone cement sandwich was done. Average hospital stay was 6.6 days (SD 2.3, range 3-9 days). Conclusion Chest wall tumor can have different histopathological findings. In patients where wide resection is possible, it can be repaired by either primary repair or by repair using double prolene and bone cement sandwich.

(Kathmandu University, 2022) Vaidya, N; Karmacharya, RM; Vaidya, S; Bade, S; Bade, S; Paudel, K; Kandel, G; Thapa, P; Maharjan, R; Duwal, S; Karki, Y
ABSTRACT Hemoptysis is a crucial entity taking into account its morbidity and mortality. Pulmonary tuberculosis is the leading cause for massive hemoptysis in our part of the world, which if left untreated may be life threatening. We present a case of a 37-year-old male patient with pulmonary tuberculosis with concurrent pulmonary thromboembolism presenting with massive hemoptysis, which was successfully managed with Bronchial Artery Embolization. This case represents that this measure can be a viable therapeutic choice for a patient with a severe life- threatening hemoptysis, particularly when other treatment options are unavailable or ineffective.

Nonsyndromic Complete Second Branchial Cleft Fistulas: A Clinicosurgical Experience
(Kathmandu University, 2025) Ghimire, SB; Dhakal, A; Pandey, A; Vaidya, S
ABSTRACT Branchial cleft anomalies are congenital malformations resulting from the abnormal persistence of branchial clefts during embryogenesis, often presenting as cysts, sinuses, or fistulae. These anomalies account for approximately 20% of pediatric head and neck masses, with bilateral cases being particularly rare. This report discusses a case of an 11-year-old boy with complete bilateral second branchial cleft fistulae, characterized by intermittent mucopurulent discharge and recurrent inflammation, primarily following upper respiratory infections. Diagnostic imaging, including CT scans, confirmed the presence of bilateral fistulous tracts. Surgical management involved a combined transoral and transcervical approach, including bilateral tonsillectomy and complete excision of the fistulous tracts. The procedure resulted in successful removal of the anomalies without postoperative complications. This case emphasizes the importance of thorough diagnostic evaluation and the effectiveness of complete surgical excision in managing bilateral branchial cleft anomalies to prevent recurrence and improve patient outcomes. Further research is warranted to optimize surgical techniques and postoperative results. KEY WORDS Congenital neck mass, Excision, Second branchial cleft fistula
Sensitivity and Specificity of Ankle Brachial Index for Diagnosis of Peripheral Arterial Disease in Diabetic Patients Presenting to University Hospital of Nepal
(Kathmandu University, 2025) Karmacharya, RM; Vaidya, S; Yadav, B; Sharma, S; Bhatt, S; Bhandari, N; Bhandari, S; Maharjan, S; Bhusal, J
ABSTRACT Background Diabetes is a significant risk factor for peripheral arterial disease (PAD) that increases morbidity and mortality. Hence, early detection of peripheral arterial disease is necessary. Evidence shows Ankle Brachial Index (ABI) as a promising test to diagnose peripheral arterial disease. However, sensitivity and specificity need to be evaluated before clinical use. Objective To determine Ankle Brachial Index sensitivity and specificity for the diagnosis of peripheral arterial disease in diabetic patients. Method Diabetic patients were recruited from Dhulikhel Hospital. Doppler ultrasonography (DUS) was done in all the recruited participants and peripheral arterial disease was assessed. Based on Jager’s criteria, those with grade III and IV stenosis were diagnosed as peripheral arterial disease and underwent ankle brachial index. Ankle brachial indexscores below 0.9 and above 1.5 were considered abnormal. The diagnosis by ankle brachial index was matched against the gold standard doppler ultrasonography to determine its specificity and sensitivity. Descriptive statistics and independent t-tests were used for statistics. P-value < 0.05 was considered statistically significant. Result There were total of 237 diabetic patients of which 31.2% had peripheral arterial disease. We found high sensitivity and specificity of ankle brachial index when tested against doppler ultrasonography with the values ranging from 88.68-89.66% and 86.67-90% respectively. Conclusion Ankle brachial index can be used in clinical settings to diagnose peripheral arterial disease in individuals with diabetes mellitus.

(Kathmandu University, 2022) Singh, AK; Karmacharya, RM; Vaidya, S; Shrestha, I; Siwakoti, S
ABSTRACT Background Varicose vein is one of the commonest problems that patients visit to a vascular out patient services (OPD). It causes a great deal of morbidity in today’s population. Objective To see the correlation between the size of great saphenous and Saphenofemoral junction incompetence. Method From January 2019 till January 2020, 396 patients with symptomatic or clinically diagnosed varicose veins were screened for Saphenofemoral junction reflux. The diameter of the saphenous vein was measured with B-mode imaging, and reflux was quantified based on valve closure time using Doppler spectral measurements. Best saphenous vein diameter cutoff for predicting reflux was determined using receiver operating characteristics curve analysis. Result Out of 792 limbs, the Great Saphenous Venous System was involved in 452 limbs, the Short Saphenous Venous System was involved in 151 limbs and significant perforators were present in 240 limbs. Mean great Saphenous Vein diameter of diseased limb (Reflux Positive) was 5.68 mm and 4.0 mm in control group (Reflux Negative). Mean Saphenofemoral junction diameter was 8.23 mm in diseased limbs and 6.16 mm in control limbs. Receiver operating characteristics curve showed great saphenous vein diameter at femoral condyle of 4.5 mm as best cut-off value for diagnosis of sapheno femoral junction reflux. Conclusion Great Saphenous Vein diameter at femoral condyle of 4.5 mm is the best cut-off value for diagnosis Saphenofemoral junction reflux. The Sensitivity and specificity of this cut off value is 81.8% and 71% respectively. KEY WORDS Doppler, Great-saphenous veins, Radio-frequency ablation, Varicose veins
Traumatic Diaphragmatic Hernia: Diagnostic Dilemma
(Kathmandu University, 2017) Vaidya, S; Biswas, M; Rai, K
ABSTRACT Traumatic rupture of the diaphragm is an uncommon condition. The prevalence of diaphragmatic rupture among blunt trauma victim ranges from 0.8 to 8%. The etiologic factors are blunt trauma (for example, in motor vehicle accidents) and penetrating trauma. The diagnosis is often missed because of non-specific clinical signs, and the absence of additional intra-abdominal and thoracic injuries. We present a case which was misdiagnosed as a case of left sided hemopneumothorax and treated with tube thoracotomy in other center. KEY WORDS Diaphragmatic, Thoracotomy, Traumatic rupture
