Deformity, being synonymous with the stigma of leprosy, is a definite social problem in children. In this study we have focused on the burden of deformity in children with leprosy, and various factors responsible for the deformities are discussed. We have observed an incidence of 10.5% of Grade II deformities in children with leprosy, which is very high compared to the community rate of 1.4%. Various factors which contributed significantly to the deformities in our study were: increasing age of children, delay in accessing health care, multiple skin lesions, multibacillary disease, smear positivity, multiple nerve involvement, and reaction at the time of presentation to the hospital. Logistic regression analysis showed that children with thickened nerve trunks had 6.1 times higher risk of developing deformities compared to those who did not have nerve enlargement. Children with the above risk factors should be followed up more frequently so as to detect any deformity as early as possible.</p>","PeriodicalId":14078,"journal":{"name":"International journal of leprosy and other mycobacterial diseases : official organ of the International Leprosy Association","volume":"73 4","pages":"243-8"},"PeriodicalIF":0.0,"publicationDate":"2005-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26135349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The degree of apoptosis in skin lesions of leprosy was studied by histopathologic examination (HPE) and by DNA fragmentation and electrophoresis. The effect of various parameters on apoptosis was noted in untreated disease, during treatment at 3 and 6 months, and in lepra reactions in different parts of the spectrum of leprosy. Of the 31 patients, 13 had paucibacillary (PB) and 18 multibacillary (MB) disease. Twenty one patients were in reaction: 16 had type 1 reaction and 5 had type 2 reaction. The controls included patients with non-granulomatous skin diseases; there were no normal controls, and no separate controls for cases with reaction. Apoptosis occurred more frequently in patients with leprosy as compared to the controls. In both PB & MB lesions, apoptosis was observed to increase progressively with treatment at 3 and 6 months, and was more prominent in the MB cases at 6 months of treatment. When lesions in either type 1 or type 2 reaction were compared to lesions not in reaction, a significant increase in apoptosis (p = 0.014) was found only in lesions with type 2 reaction and those which were at 6 months of treatment. The type of treatment regimen, or oral steroids given for reactions, did not significantly alter the degree of apoptosis. Our observations indicate that increased apoptosis is present in leprosy lesions and that in leprosy it progressively increases with anti-leprosy treatment up to 6 months. If the process of apoptosis in skin lesions is followed up for a longer period of time, the degree of apoptosis may be expected to decline. The study of apoptosis may help to understand the mechanism of clearance of bacilli and resolution of granulomas in leprosy patients.</p>","PeriodicalId":14078,"journal":{"name":"International journal of leprosy and other mycobacterial diseases : official organ of the International Leprosy Association","volume":"73 4","pages":"269-76"},"PeriodicalIF":0.0,"publicationDate":"2005-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26135354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unanticipated clinical findings were a male to female ratio of nearly 1:1, a 21 month median time of onset of erythema nodosum leprosum (Type 2 reaction) after starting antibacterial treatment, and an absence of a stocking-glove pattern of anesthesia in 7 patients. The only unanticipated histologic finding was a lepromatous-granulomatous vasculitis, occurring in comparatively large vessels, or in vessels made large by pathologic changes, located near the dermal-subcutaneous interface. This finding was present in 6 of the 22 patients with histologic material available for review. In 2 of these 6 this vasculitis was identified before the onset of Lucio's phenomenon. With one conspicuous exception, the onset of treatment with a microbicidal agent was associated with a cessation of new lesions of Lucio's phenomenon within one week. Long-term morbidity, other than Type 2 reaction, was found in 22 of the 25 patients followed for more than 1.3 years. Usually this was the consequence of Latapi's lepromatosis, specifically venous insufficiency and/or loss of protective sensation, and only rarely from Lucio's phenomenon, specifically scar formation. Briefly summarized are the seven patients who had had a skin biopsy before the onset of Lucio's phenomenon, as well as the two patients who were considered to be atypical. Criteria for the diagnosis of Latapi's lepromatosis, in the absence of Lucio's phenomenon, are also considered.</p>","PeriodicalId":14078,"journal":{"name":"International journal of leprosy and other mycobacterial diseases : official organ of the International Leprosy Association","volume":"73 3","pages":"169-88"},"PeriodicalIF":0.0,"publicationDate":"2005-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26135357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
