Summary The assessment of the thickness of the superficial peripheral nerve trunks to document nerve involvement is an important aspect of clinical examination in case finding for leprosy, and is usually done by trained ' paramedical workers (PMWs). This assessment is subject to variability and has implications on the outcome of the survey. The present study proposes to quantify this variability. In this study, 242 individuals, consisting of 50 neuritic cases, 143 nonneuritic cases of leprosy and 49 normal controls, selected from the records of the trial of BCG prophylaxis in leprosy in South India, were examined by a doctor and paramedical workers. Repeatability of nerve thickness assess ment for ulnar and popliteal nerves between the medical officer (MO) and the PMWs was quantified using Kappa statistics. The Kappa values for repeatability between the MO and the PMWs ranged from 0·45 to 0'54 and 0'52 to 0·69 for ulnar and popliteal nerves, respectively. The implications of the variability in nerve assessment are discussed.
A 9-month-old male child with tuberous sclerosis complex presented with ash-leaf macules on the left periocular region and ipsilateral dense cataract. Fundus showed retinal astrocytic hamartomas. This case is reported for unilaterality of congenital cataract on the same side of eyelid ash-leaf macule in tuberous sclerosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
