Publication A rare case of pancreatic mediastinal pseudocyst(Kathmandu University, 2007) Prasad, BR; Paudel, KPancreatic pseudocysts are the most common cystic lesions of the pancreas, accounting for 75-80% of such masses. Pancreatic pseudocyst with mediastinal extension is a rare clinical entity and only a handful cases report on dysphagia associated with mediastinal pseudocyst formation.1 We present a case of pancreatic mediastinal pseudocyst that presented with palpitations and dysphagia. Demonstration of cystic lesion in relation to the pancreas on ultrasound and mediastinal extension of the cyst on CT suggested the diagnosis. Key words: pseudocyst, mediastinal cyst, pancreasPublication 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 Scimitar syndrome(Kathmandu University, 2008) Kumar, A; Paudel, KAbstract A seven month old female child admitted to intensive care unit with increasing respiratory distress. Clinical examination revealed absence of cyanosis, wide and xed normal intensity second heart sound. Chest radiograph revealed crescent like radio opacity in right lower lung and subsequent contrast enhanced computed tomography (CT) chest demonstrated abnormal vessel in right lung draining into the inferior vena cava. Key words: Scimitar syndrome, partial anomalous pulmonary venous return, computed tomographyPublication Unusually large prostatic utricle cyst(Kathmandu University, 2009) Paudel, K; Kumar, AAbstract Prostatic utricle cyst is one of the uncommon conditions and only a few cases have been reported. We present a case of unusually large prostatic utricle cyst in a 13- year- old male. He presented with burning urination and post-void dribbling of urine. A cystic mass was felt on digital per rectal examination. Ultrasound pelvis revealed a well-de ned midline cystic mass posterior to the urinary bladder. Subsequent magnetic resonance imaging (MRI) of the pelvis demonstrated uid containing cystic lesion communicating with posterior urethra. Surgical resection of the cyst was performed through the posterior sagittal approach. Follow up of the patient after three months of operation, there was complete resolution of the symptoms. Key words: Prostatic utricle cyst, MRI, UltrasoundPublication When left ventricular failure complicates chronic obstructive pulmonary disease: Hypoxia plays the major role(Kathmandu University, 2008) Paudel, B; Dhungel, S; Paudel, K; Pandru, K; Paudel, RAbstract Introduction: As the chronic obstructive pulmonary disease (COPD) progress, is usually accompanied by involvement of the both left ventricle (LV) and right ventricle (RV), and their systolic and diastolic function. Signs and symptoms of LV failure can be difficult to distinguish from those of COPD. Objective: The study was carried out to determine the prevalence of LV systolic dysfunction in the COPD patients and to assess the possible risk factor behind such development. Material and Methods: It is a prospective study of 60 cases of COPD patients with or without cor-pulmonale attending Manipal Teaching Hospital. Results: The prevalence of LV systolic dysfunction was found to be 26.7%, and the findings directly correlate with the severity of COPD i.e., the more the severity of the lung disease more the probability for the incidence of LV systolic dysfunction. These data are in support of the hypothesis that hypoxia and the excess accumulation of toxic metabolic products like lactic acid, significant right-to-left shunting through the bronchial circulation explains the diminished LV ejection fraction in severe COPD patients. Conclusion: Routine echocardiography investigation of the severe COPD patients is required for assessing the status of LV function and to rule out the possible association of LV systolic dysfunction. Key words: Chronic obstructive pulmonary disease, Cor-pulmonale, Hypoxia, LV systolic dysfunction
