title: Clinical, bacteriological, and histopathological characteristics of newly detected children with leprosy: a population based study in a defined rural and urban area of Maharashtra, Western India.
abstract: BACKGROUND
  Leprosy has been a major public-health problem in many developing countries for centuries. According to the National Leprosy Elimination Programme report of March 2012, there were a total of about 0.13 million cases of leprosy in India, 9.7% of which were children. Numerous studies have investigated child leprosy amongst reported cases however, studies pertaining to proportion and characteristics of undetected childhood cases in the community are very few.
  
  
  OBJECTIVE
  To examine the clinical, bacteriological, and histopathological characteristics of newly detected child leprosy cases in the community.
  
  
  METHODS
  The population survey conducted from June to September 2007 and the defined rural areas, which included five primary health centers of Panvel Taluka, in Raigad district and urban areas, which included M-east ward of the municipal corporation of greater Mumbai of western Maharashtra, India.
  
  
  RESULTS
  House-to-house survey yielded 32 and 37 so far, undetected child cases of leprosy in the rural and urban region, and the prevalence rate was 10.5 and 1.5 per 10,000, respectively. The age of child leprosy cases detected, ranged from 3 to 14 years with a mean of 10.06 ± 3.35 years in the rural and 9.97 ± 3.12 years in the urban area. Most of the cases were paucibacillary (62%). A large proportion of children (49%) had single skin lesion (SSL). Of the 19 SSL cases examined histopathologically, 15 (99%) showed features of borderline tuberculoid, 1 (5%) borderline lepromatous and 3 (16%) had indeterminate type of leprosy. Tuberculoid leprosy was not seen in any, indicating less likelihood of self-healing. Overall, three cases had deformity (grade 1 = 1 and grade 2 = 2) and 31% of multibacillary cases were smear positive.
  
  
  CONCLUSIONS
  The clinical, bacteriological, and histopathological characteristics of newly detected child cases in the community evidently indicate the grave nature of the problem of undetected child leprosy, recent active transmission, and highlight implications on individual patients and the community.
  
  
  CONCLUSIONS
  Most of the cases were paucibacillary (62%). A large proportion of children (49%) had SSL and (55%) had it on the face followed by arms and leg (27%) and trunk (17%). The mean duration of symptoms exceeded one year which can be attributed to poor knowledge of leprosy or barriers in access to health care or its utilization.
