Publication 64-Slice CT Scan in Kathmandu Medical College Teaching Hospital(Kathmandu University, 2008) Karki, DB; Neopane, A; Regmi, S; Acharya, SAbstract 64-slice CT scan is a versatile newly introduced imaging technology, which is capable of diagnosing various diseases from head to toe. The 64-slice CT coronary angiography has a negative predictive value of 100%. Virtual images of bronchi, stomach and colon can provide definite diagnosis. Coronary artery calcification score which predicts coronary artery disease can be calculated by 64-slice CT scan. Key words: coronary angiography, coronary calcificationPublication An update on pulmonary arterial hypertension(Kathmandu University, 2007) Karki, DB; Neopane, A; Regmi, SNAPublication Atrial Fibrillation: How should it be treated?(Kathmandu University, 2007) Karki, DB; Neopane, A; Regmi, SNAPublication Breech Presentation Among Nullipara at Term: An Indication for Caesarean Section(Kathmandu University, 2012) Dongol, A; Regmi, S; Manandhar, S; KC, SABSTRACT Background Breech is the commonest malpresentation. Vaginal breech delivery in a nulliparous lady carries higher risk than in multiparous ladies. Poor neonatal outcome following vaginal delivery has made the mode of delivery a matter of controversy. Objective To evaluate the outcome of planned caesarean section among nullipara ladies with breech presentation. Method This is a prospective, analytical study conducted in Dhulikhel Hospital Kathmandu University Hospital from January 2008 to June 2012 among 102 nullipara ladies at term gestation with breech presentation. All cases underwent caesarean section either elective or emergency. During section cause of breech presentation was searched for. Neonatal condition was evaluated using APGAR Score, need for resuscitation and admission in NICU. Post partum status was also recorded for evaluation of maternal morbidity and mortality. Results These Nullipara ladies often had some reason for breech presentation, the most common being cord around the neck. Perinatal outcome was uneventful in 97(95%) neonates, there were two (2%) still birth and three (3%) needed NICU care. APGAR was good in 92 neonates, average in eight and poor in two. Total 16(15.6%) ladies stayed hospital for more than eight days. Among them 11(10.7%) developed wound infection and five stayed in hospital waiting for baby. Conclusion Nullipara ladies with breech presentation should have elective caesarean section as a preferred route of delivery.

We report a case of Acute Liver Failure due to Dengue during a major outbreak in 2010 in Chitwan. A 20 year old previously healthy female presented to the emergency department of Chitwan Medical College with fever, jaundice and altered sensorium. She was tested positive for Dengue IgM. Her biochemical and clinical parameters were suggestive of acute liver failure with total billirubin of 10.1 mg/dL, direct billirubin of 5.2 mg/ dL, ALT 5760 IU, AST 14100 IU, alkaline phosphatase of 1250 IU, PT INR of 1.76 and platelet count of 30,000 /mm3. Other causes for acute hepatic failure like acute viral hepatitis, leptospirosis, malaria, Reye’s syndrome were ruled out. The patient was admitted and managed in the ICU with supportive care and platelet transfusion. With treatment she made a significant clinical and biochemical improvement with AST of 105 IU, ALT of 120 IU and platelet count of 150,000/mm3. She was discharged after 11 days of hospital stay.

Increase in the nuchal translucency thickness is associated with various congenital anomalies. Objective To study the relationship between nuchal translucency thickness, crown rump length and gestational age in normal fetus. Methods Prospective analytical study conducted on 211 pregnant women from March 2011 to August 2012. Measurement of Nuchal translucency thickness and crown rump length was performed by ultrasound at 11-14 weeks of gestation. The relationship between nuchal translucency thickness, crown rump length and gestational age was studied by using linear regression analysis. Results The mean CRL was 63.67+13.48mm (range 41.2-88mm) and mean NT thickness was 1.55+0.35mm (range 0.8-2.7mm), respectively. The median gestational age was 12.9 weeks. The regression equation which shows relation between median NT thickness and CRL was described as follows: expected NT thickness = 0.013CRL+0.725, (R2 = 0.258, p <0.001). There was increase in the incidence of NT thickness more than or equal to 2.5mm; 1.7% in fetus between 12-12.9 weeks of gestation to 15.1% in fetus between 14.0-14.9 weeks. Conclusion Our study offers normative data of NT thickness in normal fetus, which can be used as reference to screen various chromosomal and congenital abnormalities between 11- 14 weeks of gestation. NT thickness increased with increasing CRL and a false positive rate increases with increasing gestational age.

Objective To compare the role of ultrasound with endoscopic retrograde cholangiography and to determine the major causes of obstructive jaundice in our prospect. Methods This was a prospective, analytical study conducted on 88 patients presenting to Department of Radiodiagnosis and Imaging at Dhulikhel Hospital-Kathmandu University hospital from March 2011 to August 2012 with clinical diagnosis of obstructive jaundice. Sonographic evaluation was performed in Siemens acusion x-150 and x-300. The final diagnosis was made by endoscopic retrograde cholangiography and /or surgery and confirmed histopathologically. Results The most common benign causes of obstructive jaundice were choledocholithiasis (63%), CBD stricture (12.3%), cholangitis (8%) and pancreatitis (6.85%) whereas cholangio carcinoma (6.85%) and carcinoma head of pancreas (4%) comprised of the malignant causes . Ultrasonography had sensitivity of 100% and specificity of 89% in detecting choledocholithiasis. It was found to be 98.78% sensitive and 83.33% specific in cholangiocarcinoma. Similarly in pancreatitis, the sensitivity of ultrasonography was 97.59% and sensitivity was 66.67%. Conclusion Ultrasonography acts as a valuable diagnostic imaging modality in detecting the causes of obstructive jaundice. Due to its easy availability, non invasive nature and cost effectiveness, it can be considered as the first line imaging technique/ tool. ERCP is the invasive imaging tool and can be used for both diagnostic and therapeutic purpose.

However due to concerns regarding radiation exposure, sonograms are re-emerging as imaging methods in such situations. Objectives To evaluate the role of sonography in detection of calculus in acute ureteric colic. Methods Total 384 patients were enrolled. Hydronephrosis was graded as mild, moderate or severe. Calculus was detected as an intraluminal echogenic focus with distal shadowing with twinkling artifact. Number, size and position of the calculi were assessed. Patients were categorized into four groups:I. ureteric colic only II. ureteric colic with hematuria III. ureteric colic with hydronephrosis and IV. ureteric colic with hematuria and hydronephrosis and then the possibility of detection of calculi has been compared among these groups. Results Out of 384 patients, 254 were found to have calculi ranging between 2.7-27mm. Nineteen had in the pelvis/ pelviureteric junction, 64 in proximal ureter, 125 in distal ureter, 6 at iliac crossing and 40 at vesicoureteric junction. Two hundred forty one had single and 14 had multiple calculi. Calculus detection is easier in category III and IV patients. The sensitivity and specificity of ultrasonography were 87.98% and 93.07%. Degree of hydronephrosis is strongly correlated with the number of calculi but weakly correlated with the size of the calculus. Conclusion Sonogram can be used in all cases of acute ureteric colic. Hydronephrosis is the most important finding because it paves the way out for the detection of calculus. KEY WORDS Calculus, hydronephrosis, sonography, ureteric colic
