ABSTRACT
This study was done during 1992 to 1994. the patients were in-patients of Wards 1 & 2 and those referred from the Nuclear Medicine Department of Yangon General Hospital. they all were clinically thyrotoxic patients confirmed by either high uptake of radioactive iodine or high serum T3 and T4 levels. We took proper history taking and did thorough clinical examination for all patients. Then we recorded the findings and counted the scores for each patient according to YGH index and WAYNE index for diagnosis of thyrotoxicosis. The total numberr of patients studied was 138. Mean age was 36.5 years. The sensitivity of YGHindex was 93.47 percent. The sensitivity of WAYNE index was 89.85 percent. The difference between the sensitivities of two scoring systems was not significant statistically. Therefore, both scoring systems can be applied with the nearly same sensitivity in the clinical diagnosis of thyrotoxicosis.
