INTRODUCTION & OBJECTIVES: The aim of this study was to demonstrate the anatomical relationship of the parotid duct to the buccal and zygomatic branches of the facial nerve and provide information to preserve these structures in parotid surgeries. METHODS: Fifteen cadavers (20 parotid areas) were dissected at the Anatomy Department, Faculty of Medicine, University of Kelaniya to demonstrate the pathway of the parotid duct and course of the buccal and zygomatic branches of the facial nerve. Twelve Anatomical parameters were measured by a flexible tape. RESULTS: Of 20 specimens, two (10%) had two buccal branches, two (10%) had two zygomatic branches, one had an accessory parotid gland, one had an accessory parotid duct. Mean parotid duct length was 34.88mm (SD-6.31, CV-18.09). Mean distance between the beginning of the parotid duct and the point at which the zygomatic nerve crossed the duct was 19.36mm (SD-6.82, CV-35.19%). The average distance between the lateral canthus and intersection point of the zygomatic nerve and duct was 52.45mm (SD-3.15, CV-6.05%). Mean distance between the zygomatic arch and the above intersection point was 20.73mm (SD-2.49, CV-12.01%). CONCLUSION: The reliable measurement in our study with the smallest coefficient variation was the distance between the lateral canthus and intersection point of the zygomatic nerve and parotid duct; 52.45mm. Thus the intersection point of the zygomatic nerve and duct lies between 46.15 - 58.75mm from the lateral canthus. If two circles are drawn with radii of 46.15mm and 58.75mm from the lateral canthus the duct will mark a segment along its pathway, within which 95% confidence the intersection point with the zygomatic branch will lie.
A multicentre study on pattern of fetal anomalies detected in Sri Lanka
(Sri Lanka College of Obstetricians & Gynaecologists, 2017) Padeniya, A.G.P.M.; Dias, T.D.; Ediriweera, D.S.; Mendis, B.M.I.U.
OBJECTIVE: Prenatal diagnosis is a rapidly evolving specialty in modern medicine. The mid-trimester scan has been an important practice in safe antenatal care which predicts birth defects of the developing fetus. This scan performed during 18-23 weeks of pregnancy detects both internal and external abnormalities of the fetus. The objective of this study was to present the pattern of fetal anomalies detected in Sri Lankan pregnant women who were referred for the anomaly scan. METHOD: A multi centre retrospective study was carried out in all the fetal medicine referral centers conducted in the Island including Colombo, Ragama, Galle and Kurunegala between July 2013 and March 2017. Patient information and the ultrasound scan findings were obtained from the purpose built database maintained by the authors. RESULTS: A total of 7370 referrals were reviewed and 6704 singleton pregnancies were selected. The mean maternal age and the mean gestational age at which the anomaly scan was performed were 31 years (SD=4.9) and 23 weeks (SD= 4.5) respectively. Congenital Heart Disease (CHD) was the commonest abnormality detected in the study group 149 (2.2%). Thirty-one (0.5%) fetuses had Atrioventricular Septal Defect which predicts Down syndrome at the mid-trimester scan. Majority (8.3%) of the CHD were referred from the Uva province. Of the 7370 referrals 63 (0.9%) and 27 (0.4%) had Neural Tube Defects (NTDs) and cleft lip/palate respectively. Highest percentage (4.4%) of NTDs were referred from the North Central province and cleft lip/palate referrals were commonest in Sabaragamuwa (0.9%) province. Abdominal wall defects and cystic renal disease were detected in 33 (0.5%) and 38 (0.6%) fetuses correspondingly. Referrals received from the Uva (1.9%) province reached the highest number of abdominal wall defects and cystic renal disease referrals were peaked in the Uva (7.4%) province. Forty-eight (0.7%) referrals had Congenital Talipes Equino Varus deformity and highest number of referrals was from the Eastern (2.4%) province. CONCLUSION: Referrals received from the Uva province had highest number of fetal anomalies (20%) either as a major or minor birth defect. Of the total referrals congenital heart defect was the commonest congenital abnormality detected in the study group.

Introduction and Objectives Pyrexia of “unknown origin” remains a clinical entity universally despite advances in diagnostic technologies. There are few if any systematic studies on PUO conducted in Sri Lanka. We retrospectively analysed data of patients with PUO from a tertiary care hospital. Methods Records of PUO patients admitted to Colombo North (Teaching) Hospital during the period of January 2015 – January 2020 were extracted from the archives. Details of etiology, diagnosis and usage of medication of each patient was recorded. Results A total of 100 PUO patients were recruited. Majority were males (n=55;54.5%). Median ages of male and female patients were 53.0 and 50.0 years respectively. A final diagnosis had been reached in the majority (n=65;65%). Mean number of days of hospital stay was 15.16 (SD; 7.81). Median of the total number of fever days among PUO patients was 30.5. Out of 65 patients whose etiology were identified, the majority were diagnosed with an infection (n = 47; 72.31%) followed by noninfectious inflammatory conditions (n=13; 20.0%) and malignancies (n=5; 7.7%). Tuberculosis was the commonest infection detected (n=15; 31.9%). Mean number of days taken to reach the final diagnosis was 11.57 (SD: 11.42). Contrast enhanced CT scan (CECT) pelvis/abdomen (n = 15; 23.1%) was the commonest investigation leading to the final diagnosis. Antibiotics had been prescribed for the majority of the PUO patients (n=90; 90%). Conclusion Infections, mainly tuberculous, was the commonest cause for PUO while a third of patients remained undiagnosed despite a prolonged hospital stay.
