Impaired warm and cold perception thresholds in leprosy skin lesions

The aim of the present study was to determine the frequency of alteration in warm perception thresholds (WPT), cold perception thresholds (CPT) and the warm and cold perception interval (WCPI) in leprosy-suspected skin lesions, and to determine if these tests could assist in the diagnosis of leprosy. Tests were conducted using a thermal sensory analyser TSA-2001 (Medoc Ltd, Israel) and the method of levels. A cross-sectional study of 112 patients presenting leprosy-suspected skin lesions ('patch'), with no clinical evidence of peripheral nerve damage, was conducted. Leprosy diagnosis was based on clinical dermato-neurological examinations and complementary tests. One hundred and eight subjects (45 males, 63 females; average age 37.7 years) completed the tests: 82 were positively diagnosed with leprosy and 26 with diseases of different etiologies. The mean values of WPT (45-63 +/- 5.59), CPT (9.64 +/- 11.34) and WCPI 36.01 +/- 15.58) registered in leprosy-skin lesions were significantly different (P < 0.001) from lesions of diverse aetiologies and skin area without lesions. The cut-off point for WPT as determined from the ROC curve (receiver operating characteristic) was 35-10 degrees C, with a sensitivity of 90.2% and a specificity of 100%, and the corresponding cut-off point for CPT was 28.95 degrees C, with a sensitivity of 92.7% and a specificity of 100%. Nevertheless, all patients with leprosy presented a WCPI greater than 6.10 degrees C (ROC curve) in skin lesions. Increase in the thermal thresholds indicated warm hypoaesthesia, cold hypoaesthesia or both. The WCPI, which embraces both warm and cold perception thresholds, was the best indicator of thermal sensation, a term used in literature as a non-specific expression that does not describe warm and cold stimuli explicitly in terms of units of temperature.     

Medical and social concerns of leprosy cured after integration in India

In order to understand nature of the medical and society related problems of leprosy cured individuals from various socio-cultural groups and develop proper system to address the current needs of leprosy cured, data have been collected from leprosy cured, employing qualitative methods such as FGDs, open ended interviews and participant observation and a quantitative survey method. The findings show that there has been not much change in the socio-cultural and economic situation of the leprosy cured especially the disabled ones, except a recognition in the health system that their anti-leprosy treatment is completed. In the present integrated health care system, disabled leprosy patients are also expected to seek their own health care by themselves along with general public, which is not happening because the leprosy cured are not yet perceived to be cured of leprosy by community as well as by themselves. Though some of the problems of leprosy cured seem to be poverty related, qualitative analysis shows, a vast gap between poverty problem of leprosy afflicted and non leprosy afflicted. Any special programme to bridge the gap between PHC and leprosy community is required and the new functionaries like ASHA in National Rural Health Mission (NRHM) and similar developments could be of vital use to make them cured in totality.     

The fulfilment of health care needs of leprosy patients from Kaski District, Nepal

Hospital records of 142 leprosy patients from Kaski district in Western Nepal were reviewed to assess their use of leprosy related health services and the fulfilment of these needs. Use of services was reviewed from diagnosis until release from treatment. Voluntary muscle and sensory testing were on average done 15.2 times per patient Of MB patients, 65.5% had longer intervals between testing than recommended. A course of prednisolone was indicated in 40% of cases, but 10% of needed courses were not given. Twenty-eight percent needed protective footwear. Of the cohort, 10% had complicated ulcers and 28% had at least one admission. Paralytic impairments that could be corrected were present in 10% of the cohort.     

Sustainable leprosy related disability care within integrated general health services: findings from Salem District, India

The main focus of leprosy control has been case detection and treatment delivery with relative neglect of prevention of disability. Absence of reliable data and lack of research have added to the problem. This raised concerns about the capacity of the general health system to address the needs of people living with leprosy-related disabilities. In this prospective study appropriate services for people living with leprosy-related disabilities were introduced in the form of self-care training, guidance and monitoring by the general health staff facilitated by a non-governmental organisation leprosy centre in a district in south India with a population of 3.1 million (estimated in 2005). The staff identified 1232 people with leprosy-related disabilities and trained them in self-care. Follow-up assessments indicated that 86% were found to be practising self-care regularly and all the 239 general health workers were found to be actively involved. The most heartening outcome was the healing of plantar ulcers in 70% of people at the 1-year follow up. This intervention is sustainable because of the simplicity of the procedures and the involvement of all health staff including supervisors.     

Transfer of disability care of leprosy to the affected persons and the community members

Bargarh district in the western Orissa had high leprosy burden and LEPRA India supported in control activities. Its main focus was on POD care with community participation. After motivation and capacity building, it transferred the responsibility of POD care to affected persons, family, community partners and GHS staff in 2006. The effectiveness of this approach was evaluated in 2009. With personal contact responses from 112 (17%) persons with disability and 18 stakeholders were obtained. Result shows 98% affected persons are staying with family; 92% are practicing self-care; 92% felt self-care is beneficial; 57% and 36% are using commercial and MCR footwear respectively. Surgical correction of deformity is maintained in 80% of cases. Difficulty in activity and in community participation was experienced in about one third of affected persons the latter is mostly due to self stigma. The facilitators were happy with their beneficiaries.     

对综合性医院医务人员掌握麻风诊断知识和技能的调查

麻风防治是一项长期任务;基本消灭不等于完全消灭。在防治的后期,决策者和项目管理人员必须面对两大问题,即康复和早期发现散在的病人。近年来,山东省每年仍发现新病人约50名,其中约20%有2～3级畸残。因此,早期发现的工作仍有待改善。由于在防治后期,病人分布极为分散,普查、线调等方法已没有效益;接触者检查也不能每年进行,且所发现的病人占新病人的比例越来越低。充分利用各级综合医疗机构早期发现病人可能是解决该问题的方法之一。因此,调查各级综合医院医务人员对麻风的诊断知识和技能,对制定相应对策是必要的。     

Social stigma: a comparative qualitative study of integrated and vertical care approaches to leprosy

Integration of leprosy into the general health system is very much emphasized by health care planners. One prime reason stated for this is to reduce stigma attached to this disease. This study was conducted in the state of Maharashtra, India, to compare the level of social stigma towards leprosy in communities with a vertical and an integrated programme. The data were collected in three areas of five villages each. The first two areas were in an integrated programme to test for internal consistency and the third in a vertical programme. All the leprosy patients with visible deformities in these villages were enrolled in the study, and an in-depth stigma measurement scale was administered. In addition, focus group discussions were conducted among the family members of leprosy patients and participative rural appraisal was done in the communities. The data were analysed using qualitative methods. A total of 24 leprosy patients with visible deformities participated in the in-depth stigma measurement exercise from 15 villages. Fifteen focus group discussions were conducted with families of leprosy patients and an equal number of participatory rural appraisals with communities were done. The results show that social stigma was virtually non-existent among the communities with the integrated approach and minimally experienced by leprosy patients in this model. However, a high level of self-stigmatization among leprosy patients was observed in the vertical approach and equally a high level of social stigma was found in their communities, which led to reduced interaction between the leprosy patients and their communities. The integrated approach to community-based primary health care is effective in reducing leprosy stigma in society.
