Item FNAC in the 'field'- a new experience(Sri Lanka Medical Association, 2008) Fernando, R.; Hewavisenthi, J.; Pathmeswaran, A.; Edirisinghe, D.; Abeysinghe, S.; Atulugama, N.; Bandara, D.; Premathileke, M.BACKGROUND: Fine needle aspiration cytology (FNAC) is an important diagnostic test in thyroid diseases. It usually is undertaken at a hospital or laboratory setup. As part of an islandwide field based study, FNAC was undertaken in the field. Literature review revealed that FNAC accuracy rate was around 65-70% in most Centres with full-fledged facilities. OBJECTIVES: To determine the effectiveness of FNAC done in the field DESIGN, SETTING AND METHODS: Informed written consent was obtained and the goitre was delineated with a marker pen. FNAC was carried out by a trained team member in the standard manner. Four slides were prepared from each patient. All slides were processed and examined by a cytologist RESULTS: 308 FNAC were done. 226 FNAC were diagnostic (73.36%) and 82(26.64%) were non diagnostic. 62(23.8%) showed benign cells only. The pathological entities detected were: 112 (49.5%) auto immune thyroiditis, 32 (14.1%) colloid storing nodules, 14(6.1%) colloid storing nodules with autoimmune thyroiditis, 5 (2.2%) follicular lesions and one toxic lesion. There were no significant complications noted in any of the patients. CONCLUSIONS: Field FNAC has a high diagnostic accuracy if done by a trained person. It is a safe procedure in the field.Item Microscopic colitis not otherwise specified (NOS) in patients with diarrhoea predominant IBS in a tropical setting(Sri Lanka Medical Association, 2008) de Silva, A.P.; Dassanayake, A.S.; Hewavisenthi, J.; Liyanage, D.L.M.N.; Dissanayake, T.G.I.; Duminda, H.K.K.T.; de Silva, H.J.BACKGROUND: Coionoscopy is not recommended in IBS unless there are alarm symptoms. However, studies have shown that microscopic colitis and low grade inflammatory bowel disease (IBD) can mimic IBS. Microscopic colitis not otherwise specified (MNOS) is a distinct but poorly studied entity, especially in the tropics. OBJECTIVES: To investigate the presence of colonic and ileal inflammation in patients with diarrhea predominant IBS (IBS-D) in a tropicai setting. DESIGN, SETTING AND METHODS: In a prospective study over one year, we recruited 42 consecutive patients with IBS (diagnosed using Rome II criteria) and no alarm symptoms (mean age 36.1 yrs, M:F=29:13) and 13 controls {mean age 42.3 yrs, M:F=5:8). Serial colonic and ileal biopsies were obtained. RESULTS: Coionoscopy was macroscopically normal in all cases and controls. 23 (54.8%) cases had MNOS, 2(4.76%) ileal inflammation only, and 17(40.48%) had normal histology. Histology was normal in 11(84.62%) controls, and 2(15.38%) had MNOS. MNOS was significantly commoner in cases than controls (P=0.02, chi-square test). MNOS was commonest in the right side of the colon (n=20, 80%). 14(60.8%) patients with MNOS had a history suggestive of post infective IBS, compared to 7(36.8%) patients without MNOS (P>0.05). CONCLUSION: MNOS is common in patients with IBS-D in a tropical setting. Post infectious IBS seems commoner in patients with MNOS than those without MNOS, although this did not reach statistical significance. Coionoscopy with ileoscopy and serial biopsies are useful to detect mucosal inflammation in IBS-D.Item Goitre prevalence in diabetes - results of an islandwide study(Sri Lanka Medical Association, 2008) Fernando, R.; Hewavisenthi, J.; Atulugama, N.S.; Edirisinghe, E.M.D.A.R.; Abeysinghe, A.P.S.D.; Fernando, W.M.T.P.S.; Premathilaka, H.M.M.S.; Bandara, S.D.Abstracts Available
