(Sri Lanka Medical Association, 2018) Seenigama, S.O.; Wijeratne, N.G.; Chandratilake, M.; Karunarathne, W.C.D.; Fernando, M.A.M.
INTRODUCTION AND OBJECTIVES: Stress or psychological difficulties faced by doctors in the work place may result in reduced productivity, burnout and negative effects on personal wellbeing among doctors. The aim of this study was to identify causes and the outcomes of stress encountered by doctors in Sri Lanka. METHODS: Individual face to face interviews were conducted with 32 doctors belonging to all categories (Intern house officers, staff-grade medical officers, postgraduate trainees and consultants) and all 5 clinical specialties (Medicine, Surgery, Paediatrics, Obstetrics & Gynaecology and Psychiatry) attached to North Colombo Teaching Hospital, Sri Lanka. The audio-recordings were transcribed verbatim and thematically analysed. RESULTS: High workload, lack ofresources to provide effective patient care, associated legal implications, adverse reactions of seniors in pressure situations, deficiencies in the administrative system and strikes were the main causes of stress experienced by doctors during practice. It was supplemented by patient related challenges such as acuity of presentations, medical and surgical emergencies, death of patients and the need to break bad news. Furthermore, deprivation of personal time due to continued patient commitments, individual responsibility towards patient.care, guilt due to management errors, interpersonal conflicts among healthcare workers appeared to be contributory, These stressors appeared to make doctors frustrated and impede their performance by interfering with work. CONCLUSION: Main causes of stress among doctors were work and patient related, and it was augmented by both personal and interpersonal factors. Stress adversely influenced the performance of doctors thereby compromising both patient care and individual well being.

(Sri Lanka Medical Association, 2011) Ranawaka, U.K.; Harshani, M.L.; Fonseka, V.N.R.M.; Hathagoda, K.L.W.; Nawaratne, A.N.H.M.U.K.G.D.B.; Weerasooriya, W.A.L.K.; Samarakoon, S.M.S.B.; Thirumawalawan, K.; Premawansa, G.; Fernando, M.A.M.; de Silva, L.; Perera, K.V.H.K.K.; Dassanayake, K.M.M.P.; Wijesooriya, T.; Rajindrajith, E.G.D.S.
INTRODUCTION AND OBJECTIVES: Central nervous system (CNS) infections produce high morbidity and mortality, and effective treatment and outcome depend on precise microbiological diagnosis. We aimed to describe the pattern of CNS infections and accuracy of diagnosis in patients presenting to a tertiary care hospital. METHODS: We prospectively studied patients with suspected CNS infection admitted to medical and paediatric units of Colombo North Teaching Hospital over three years. Data related to demographic and clinical features, laboratory findings, treatment and immediate outcome. Diagnosis of CNS infection was categorised as definite, probable, possible, and uncertain. RESULTS: 426 patients (293 adults, 133 children) were studied [57.2% males, mean age (SD) years-adults 44(20), children 4(3.15)]. Of them, 27.5% had received antibiotics before admission. Blood cultures were done in 149 (35%) and only 14 were positive. Lumbar puncture was done in 347 (81.4%). CSF culture was positive only in two patients. CSF Gram stains and TB-PCR were all negative. The likely diagnosis was meningitis in 35.4%, encephalitis in 10.6% and a non-specific 'meningo-encephalitis' in 16.7%. A 'definite' microbiological diagnosis was made only in five patients. Diagnosis was considered 'probable' in, 53.7%, 'possible' in 8.7%, and 'uncertain' in 14.8%. An alternative diagnosis was found in 22% (13.6% adults, 40.6% children). Intravenous antibiotics (86.8%) and acyclovir (42.5%) were widely used on empiric grounds. CONCLUSIONS: Diagnosis of CNS infections is highly unsatisfactory with available facilities, even in a tertiary care setting. Better facilities are needed to improve aetiological diagnosis, and are likely to improve care and minimise treatment costs.

INTRODUCTION AND OBJECTIVES: Rickettsioses are re-emerging in Sri Lanka. Both children and adults are vulnerable to these infections. Data on paediatric rickettsioses in the country are sparse. Objectives were to study the clinical characteristics of paediatric rickettsioses based on data received by the Rickettsail Disease Diagnostic and Research Laboratory (RDDRL), Faculty of Medicine, University of Kelaniya, over the last two years. METHODS: All clinical and laboratory data of confirmed rickettsioses were analyzed. RESULTS: Out of 46 requests received by the RDDRL, 22 were positive for acute rickettsioses in diagnostic titres IFA-IgD>1:128 (all>256). Of the positives, 16 were positive for spotted fever group rickettsioses (SFG), 5 for scrub thypus (ST) and 1 for both. 4/5 ST had eschars. The mean age was 56.59 months. (43.9); the youngest affected was aged 5 months. Of the sample 12 (54.5%) were male. Fever was present in all; mean duration was 9.81 (4.5) days; fever intensity was 102.80F (1.03); frequency of spikers per day was 2.33 (0.67). clinical features were headache 12 (54.5%), body aches 9 (40.9%), joint pains 6 (27.3%), cough 14 (63.6%), shortness of breath 5 (22.7%), rash 14 (63.6%); macular popular rash 13, diarrhea 4 (18.2%), lymphadenopathy 7 (31.8%), palpable liver 4, palpable spleen 1. Total WBC 11.1x109/L (SD-4.8); neurophils-84.8% (SD-13.8) lymphocytes 40.5% (17.2). ESR 1st Hr 46.3mm (SD-26.7) CRP 42.1mg/dl (40.6) SGOT 51.2iu/L (32.1) SGPT 50.2iu/L (51.4). ECG was normal in all, Chest x-ray showed patchy shadows in 4. CONCLUSIONS: SFG rickettsioses were commoner than ST, among children living in the Gampaha and Kurunegale districts. Clinical features were similar to adults. Diagnostic investigations were requested late in the febrile illness.

(Sri Lanka Medical Association, 2013) Premaratna, R.; Karunasekara, K.A.W.; Fernando, M.A.M.; de Silva, L.; Chandrasena, T.G.A.N.; de Silva, H.J.; Miththinda, J.K.N.D.; Mufeena, M.N.F.; Madeena, K.S.K.; Bandara, N.K.B.K.R.G.W.
INTRODUCTION AND OBJECTIVES: Identification of clinical or biochemical parameters that differentiate rickettsioses from other fevers would help in clinical practice to reduce morbidity and mortality associated with childhood rickettsioses. METHODS: Clinical and laboratory parameters of 22 confirmed paediatric rickettsioses (SFG-16/22, ST-5/22, Mixed-1) were compared with those of 24 with fever who were negative for rickettsioses, based on data received by the Rickettsial Disease Diagnostic and Research Laboratory (RDDRL), Faculty of Medicine, University ofKelaniya. Results: Comparisons of clinical and laboratory parameters between rickettsioses vs non-rickettsioses were mean(SD); age in months 56.59 (43.9) vs 78.13 (42.08) (p=0.1); fever duration 9.81 days (4.5) vslO.68 days (8.79) (p-0.68); fever intensity 102.80F (1.03) vs 102.440F (1.23) (p=0.4); fever spikes per day 2.33 (0.67) vs 2.68 (0.75) (p=0.186); headache 12/22 vs 11/24 (p=0.64); body-aches 9/22 vs 9/24 (p-0.52); pain in arms and legs 6/9 vs 7/9 (p=0.5); joint pains 6/22 vs 7/24 (p=O.S9); cough 14/22 vs 9/24 (p=0.0*7); shortness of breath 5/22 vs 2/24 (p=0.19); eschar (all ST) 4/22 vs 0/24 (p=0.02); rash 14/22 vs 14/24 (p=0.69); maculo-papular rash!3/14 vs 12/14 (p=0.91); diarrhoea 4/22 vs 4/24 (p-0.89); lymphadenopathy 7/22 vs 8/24 (p=0.913); spleenl/22 vs 5/24 (p=0.18); total WBC 11.U109/L (4.8) vs 9.8xl09/L (4.8) (p=0.36); N-84.8% (13.8) vs 5.4(2) (p=0.29); ESR IstHr 46.3mm (26.7) vs 81.8mm (10.2) (p=0.37); CRP 42.1mg/dl vs 56.7mg/dl (6.7) (p=0.46); SCOT 51.2iu/L (32.1) vs 248.7iu/L (678) (p=0.43); SGPT 50.2iu/L (51.4) vs 170.7iu/L (404) (p=0.44). CONCLUSIONS: In paediatric patients, no clinical or biochemical parameter could differentiate rickettsioses from other aetiologies. Presence of eschars would help to diagnose scrub typhus. However laboratory confirmation is needed to differentiate SFG from other fevers.
Coping strategies adopted by Sri Lankan doctors to deal with stress
(Sri Lanka Medical Association, 2018) Wijeratne, N.G.; Seenigama, S.O.; Chandratilake, M.; Karunarathne, W.C.D.; Fernando, M.A.M.
INTRODUCTION AND OBJECTIVES: Doctors face psychological difficulties due to the nature of their occupation. This study was aimed at identifying work-related stress encountered by Sri Lankan doctors during practice and the available psychological support to deal with them effectively. METHODS: Individual face-to-face interviews were conducted with 32 doctors belonging to all categories (Intern house officers (IHO), staff-grade medical officers, postgraduate trainees and consultants) and all 5 clinical specialties (Medicine, Surgery, Paediatrics, Obstetrics & Gynaecology and Psychiatry) attached to North Colombo Teaching Hospital, Sri Lanka. The. audio-recordings were transcribed and thematically analysed. RESULTS: Despite considerable work related stress experienced by doctors, access to help was limited during practice. Deficiencies in the psychological support provided by the healthcare system, inconsistencies in senior support, ignorance of rules and regulations and unhelpful legislations appeared to be contributory. However, several informal means were employed by doctors to relieve their work related stress. The main coping strategies were discussions with seniors and colleagues, teamwork and religious practices. Implementation of a formal system providing professional support and mentorship, reducing the ratio of patients to medical and non-medical staff by proper allocation of human resources, flexible working locations and shift basis for work, were proposed as remedial measures by the participants. CONCLUSION: In Sri Lanka, there is no formal mechanism to help doctors in difficulty and stress. They are satisfied with the informal and inconsistent coping strategies they use, as they have no other choice. Setting-up a formal system is appreciated by many

(Sri Lanka Medical Association, 2016) Warnakulasuriya, L.S.; Fernando, M.A.M.; Adikaram, A.V.N.; Thawfeek, A.R.M.; Anurasiri, W.M.L.; Silva, K.D.R.R.; Sirasa, M.S.F.; Samaranayake, D.; Wickramasinghe, V.P.
INTRODUCTION: Childhood obesity-related metabolic derangements are increasing among South Asian populations. Dietary and physical activity plans have limited effect. OBJECTIVES: This study aims to assess effectiveness of metformin against placebo in management of childhood obesity among 8-16 year-old children in Gampaha District. METHOD: A triple-blinded control trial was conducted in a sample of 150 obese school children. After 12-hour overnight fast, blood was drawn for fasting blood glucose (FBS) and lipid profile. 2-hour OGTT was done. Anthropometry, fat mass (FM) and blood pressure were measured. Children randomly received either age-adjusted dose of metformin or placebo, with advice on diet and physical activity. Anthropometry and blood investigations were repeated at 6 and 12 months. Mean difference in outcome measures, adjusted for baseline values were compared between the two groups using ANOVA. RESULTS: There were 84/150 boys and 25 (16.7%) had metabolic syndrome. A statistically significant adjusted mean reduction was observed in metformin group compared to placebo, in weight (-0.991 vs 1.394, p=0.000), BMI-SDS (-0.287 vs -0.116, p=0.000), percentage FM-SDS (-0.092 vs 0.016, p=0.04), systolic BP (-0.415 vs 0.015, p=0.015), total cholesterol (-36.48 vs -27.32, p=0.001), LDL (-26.06 vs -17.22, p=0.001) and hsCRP(-0.143 vs 0.008, p=0.013) at six months, and in BMI-SDS (-370 vs -0.222, p=0.001), WC-SDS (-0.473 vs -0.337, p=0.018), systolic BP (-0.834 vs -0.477, p=0.023) and triglycerides (-29.30 vs-12,72, p=0.019) at 12 months. CONCLUSIONS: Metformin compared to placebo has beneficial effects on anthropometric and metabolic indicators in the management of childhood obesity.
