Cryostat sections of skin and nerve lesions of leprosy were stained with monoclonal antibodies recognising Mycobacterium leprae antigens and indirect immunofluorescence. In both the tuberculoid and lepromatous lesions, PGL1, 55-65-kDa, 17-kDa protein antigens and cross-reactive non-protein antigens were present. 65-kDa antigens were seen mainly in the skin… (More)
There is a tendency to compare the results of surgery with that of oral corticosteroid therapy in leprous neuritis as if the two are competing methods. Surgery helps by removing the external compressive force and improves circulation so that steroids can reach and effectively act at the site of inflammation, minimizing the ischaemic and compression damage… (More)
Infestation of the nose with larvae of certain files can occur in leprosy patients. This results in severe distress and agony and can cause extensive tissue damage. The predisposing factors, clinical presentation and treatment is described.
Median nerve decompression was performed in 29 leprosy patients of which 20 were followed up for varying periods. It has been observed that the decompression was beneficial, sensory recovery was seen in 90% cases and in 45% cases the muscle strength improved and the process of deterioration was arrested in another 25% cases.
Soft cystic swellings are noticed in leprosy patients during the course of disease and are seen all through the spectrum. The commonest site for these is the dorsum of wrist. At times these are seen over the dorsum and the lateral aspects of ankle as well. These contain straw colored sticky but clear fluid. On exploration these appear to arise from the… (More)
Ulnar neurolysis in 279 cases of leprosy was performed with objectives of relief in neuritic pain and impending/ existing sensory motor loss of varying extent. Of the above, 193 could be followed between 3-10 years. Neuritic pain was first to disappear. 48.7% of the 193 cases showed sensory recovery. Motor power gain and/or further fall in muscle power was… (More)
Immunohistological analysis of infiltrates of nerves in patients with neuritic leprosy was carried out using monoclonal antibodies defining T cell subsets, Langerhans cells, HLA DR antigens, and indirect immunofluorescence. In all, eight nerves were analyzed. 2 of the 8 nerves showed epithelioid cell granulomas surrounded by large numbers of lymphocytes.… (More)
BACKGROUND Peripheral nerve trunk involvement in leprosy is very common. However, by the time it becomes clinically manifest, the damage is quite advanced. If the preclinical nerve damage can be detected early, the deformities and disabilities can be prevented to a large extent. AIMS To assess the electrophysiological functions of the ulnar and median… (More)
Cryostat sections of dermal lesions from 13 untreated patients of leprosy were studied by indirect immunoperoxidase using monoclonal antibodies (MLO4 & MLO6), defining M. leprae specific antigens. The lymphocytes and macrophages in both the tuberculoid and lepromatous granulomas showed membranous staining with the above antibodies. M. leprae organisms in… (More)
Membrane attack complex (MAC) is a terminal end product produced as a result of complement activation. The deposition of MAC, in tissues, is known to have a local tissue damaging effect in several clinical conditions. Therefore, an attempt was made to demonstrate MAC in peripheral nerve biopsies, collected from leprosy patients. Interestingly, we could… (More)
