Metabolic abnormalities in diabetes mellitus involves ganglionic and preganglionic elements in the entire retina and macular region causing visual disturbances. Subclinical central nervous system (CNS) dysfunctions have been reliably detected by visual evoked potentials in patients with uncomplicated diabetes and normal brain Computed tomography (CT) scan. The offspring of diabetic parents have a higher risk of diabetes and a possibility of diabetic retinopathy. The study aims at evaluating visual evoked potential in asymptomatic, non-diabetic offspring of diabetic parents. A total of 150 individuals in each group (case and controls) were enrolled after Written and informed consent. Institutional ethical Committee approval was obtained. Visual evoked potential (VEP) recordings were done using the standard procedure given in Recommended Standards for VEP, Guidelines 9B. The statistical analysis revealed significant difference in controls and offspring of diabetic parents in terms of P100 latency in both left and right eye (P<0.05). The offspring of diabetic parents may be screened with VEP, as, prolongation of P100 latency a direct sign of retinal damage and demyelination could add the risk to the fact that they may be in a pre-diabetic stage without clinical manifestation, but there may be subclinical optic pathway involvement which mandates active intervention to reduce the co-morbidly associated with diabetes.
The WHO expert committee on leprosy, eighth report, defined a case of Leprosy as a person having manifestations of at least one of the following cardinal signs. 1 Definite loss of sensation in a pale (hypo pigmented) or reddish skin patch. A thickened or enlarged peripheral nerve, with loss of sensation and/or weakness of the muscles supplied by the nerve. The presence of acid-fast bacilli in a slit skin smear. Epidemiology Worldwide, 2 to 3 million people are estimated to be permanently disabled due to leprosy. 2
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.
