The association of hemicrania continua and leprosy has been described in 2008. This relation can be causal or casual. Hemicrania continua is a strictly unilateral, moderate to severe, continuous, indomethacin-responsive primary headache with autonomic cranial symptoms and leprosy is an usual cause of peripheral neuropathy. Prevalence has fallen in the past years, but transmission continues and leprosy remains a public health problem. The objective of this study is to report one case of headache fulfilling the IHS criteria for HC, presented during the course of leprosy. A 61 years old woman started hypo and hiperpigmented lesions with impaired sensation to touch on right side of face (malar). She had biopsy in facial lesion and histopathology compatible with a borderline leprosy form. At the same time, she reported new headaches, daily and continuous, without pain-free periods, unilateral (which were located in the same side of the leprosy lesion in face), throbbing and severe (VAS = 8) with ipsilateral conjuntival injection and lacrimation that improved with indomethacin. We hypothesize that the local injury on the face of this patient predisposes a mechanism of central sensitization, resulting in trigeminal autonomic cephalgia. Relation between trigemino-autonomic cephalalgias and leprosy provides insights into craniofacial pain mechanisms.

Unlabelled: We conducted randomized double-blind trial for single-dose of Rifampicin, Ofloxacin and Minocycline (ROM) compared to WHO-PB-MDT among paucibacillary (PB) leprosy patients with 2-5 skin lesions. We enrolled 1526 patients from five centres (ROM=762; WHO-PB-MDT=764) and followed them for 36 months posttreatment during 1998-2003. We generated information on clearance of skin lesions and relapse rates per 100 person-years (PY) for all the five centres. At base-line, the patients in the two arms were comparable. Complete clearance of skin lesions was similar (72% vs. 72.1%; p=0.95) in both the arms. Clinical scores declined steadily and equally. Difference in relapse rates was statistically highly significant (ROM=1.13 and WHO-PB-MDT=0.35 per 100 PY; mid-p exact=0.001016). Twenty eight of 38 of these relapses occurred within 18 months. In all, 10 suspected adverse drug reactions were.observed (ROM=2; WHO-PB-MDT=8). We extended the follow-up to 48 months for 1082 of 1526 patients from two programme-based centres. No further relapses occurred. Decline in clinical score was not dependent on age, gender, number of lesions or affected body parts. Single dose ROM, though less effective than the standard WHO-PB-MDT regimen conceptually offers an alternative treatment regimen for PB leprosy patients with 2-5 lesions only when careful follow-up for relapse is possible.

Severe Cutaneous Adverse Reaction (SCAR) represents the spectrum of adverse drug reactions from erythema multiforme, Stevens - Johnson syndrome (SJS) to Toxic Epidermal Necrolysis (TEN). A 55 year old lady presented in a toxic state with peeling of skin, blisters on the body of seven days duration following medications taken for fever and pulmonary tuberculosis. When referred to our institution, she was diagnosed as TEN. Immediately the suspected medications were stopped. The essential investigations were done including the screening for immunosuppression, which was found to be negative. The patient was treated symptomatically with emphasis on skilled nursing care. The patient's skin condition improved gradually but tuberculosis progressively worsened over three months. Thus patient was reinvestigated for seropositivity and was found to be positive. Considering the benefit - risk ratio along with the advice of the pulmonologist, a decision was made to give her a rechallenge test, first for antitubercular drugs and later for antipyretics. The patient developed SJS within two days of starting isoniazid (INH). On withdrawal of INH the patient recovered.

Although leprosy has been declared as eliminated in India, treated patients with persisting disabilities still require care. With the shift from vertical to integrated services, questions remain about case detection and maintaining the quality of patient care. We conducted a qualitative study to clarify the perceived status of elimination, patient care and other aspects of leprosy control from the perspective of various stakeholders. We interviewed leprosy programme managers, Non-governmental organization directors, healthcare providers, patients and community leaders from Kanchipuram district, Tamil Nadu. Consensus endorsed the current approach to integration of leprosy in primary healthcare, but healthcare personnel acknowledged problems from shortage of medicines and failure to fill key positions. Patients were concerned about limited clinic hours, long waits and delayed treatment. Disabled patients indicated how they were troubled by stigmatization of their condition. Programme managers mentioned limited support for needed research and some emphasized the potential threat of emerging drug resistance. Although consensus supports an integrated approach for leprosy services in primary care, the relative priority of different aspects of leprosy control vary among stakeholders. Perspectivist approaches to methodologically sound operational research could guide planning for effective case detection and patient care during the post-elimination era.

To assess the utility of a single stain for both mast cell count and bacillary index (BI), 50 skin-biopsie patients were stained with Fite-Faraco (FF) stain, viewed under oil immersion and BI calculated using the Ridley's logarithmic scale, and mast cells counted as the number of cells per mm2. Mean mast cell count per mm2 at the tuberculoid pole was lowest in TT 7.9 and highest in BT 14.23. At the lepromatous end, it was highest in BL 9.21, while in LL it was 8.23. Highest counts were seen in the borderline types overall. The correlation coefficient between histopathological diagnosis and BI is 0.822 which is a positive correlation to a significant degree. The correlation coefficient between histopathological diagnosis and mast cell count was found to be -0.17, which is a negative correlation but not to a significant degree. FF stain was utilised to visualise both bacilli for estimation of BI and mast cells for mast cell count, a seldom attempted feature in literature.

Leprosy is a treatable chronic infectious disease, prevalent in South Asian countries, especially India. Before labeling a patient as a case of leprosy and starting multidrug treatment for particular type, the clinical findings should be correlated and confirmed with histopathological examination and bacteriological index of skin biopsy. Skin biopsy is an important tool in diagnosing leprosy and determining the type of leprosy. In the present study, one hundred untreated clinically diagnosed cases of leprosy were studied according to Ridley-Jopling scale for confirmation of diagnosis and classification of leprosy. The study was done by routine H & E (Haematoxylin & Eosin) staining and Fite-Faraco's staining for acid-fast bacillus. The data pertaining to age, sex, clinical and histopathological classification of the type of leprosy were collected and analyzed. In analyzing the histopathology of a lesion, special attention was given to the following features, viz., invasion of the epidermis with or without erosion, involvement of the sub-epidermal zone, character and extent of granuloma, density of lymphocytic infiltrate epithelioid cells and other cellular elements, nerve involvement and the presence of Mycobacterium leprae. Histological diagnosis of leprosy was established in 98% of clinically diagnosed cases. Clinicohistopathological concordance was maximum in LL(93.75%) followed by BL(87.5%), TT(78.5%), BT(73.8%) and least in IL(27.78%). Overall, it was 60.23%. Indeterminate type of leprosy was diagnosed more on histologythan on clinical evaluation.

As the leprosy burden has declined considerably, we need to understand the current social status of the disease and patients. A qualitative study was conducted in a rural community near Chennai in Tamil Nadu, between March and October 2011. In-depth interviews with 72 leprosy patients from 25 villages and 3 focus group discussions (FGDs) with 26 women from 3 villages were conducted using a guide. The qualitative data were grouped into different domains and analysed. Most of them did not have basic knowledge on leprosy; instead there were misconceptions on cause and spread of leprosy. Nearly one third of the patients had not disclosed about the disease to their spouse, family members, relatives or friends for fear of social rejection, discrimination and ill treatment. In all, more than half of them had self-stigma and, most of them who had deformity faced actual stigma by way of disowning, isolation and social rejection. Many patients, particularly PB cases had the behavior of "denial". FGD women reported of self and actual stigma, particularly towards deformity and disfigurement, for fear of getting infected. Stigma among patients with deformity, and denial of the disease among PB cases, were highlighted. Importance of awareness programmes to remove misconceptions related to cause and spread of the disease was stressed. Need for person-centered social treatment was suggested for increased case detection.

Leprosy is a chronic mycobacterial disease whose diagnosis is primarily based on clinico-pathological examination and supported by slit skin smears for the presence of acid fast bacilli (AFB). However, definitive diagnosis of early leprosy and those suspected to have the disease but not histologically confirmed pose major public health problems. The present study reports the utility of the in situ Polymerase Chain Reaction amplification (PCR) directed at a 530bp fragment of DNA encoding the 36kd antigen of the causative Mycobacterium leprae for the diagnosis of such patients using skin biopsies of lesions. Twenty five adult patients (aged 15-50yrs) each from the clinical categories of Early and clinically Suspect leprosy were selected for the study after obtaining permission. They had solitary lesions, which were negative for AFB on slit skin smear examination. Routine histopathology confirmed the diagnosis of leprosy in 8/25 (32%) cases in the category of Early leprosy with AFB being seen in 2 biopsies, and in 5/25(20%) cases of Suspect leprosy with AFB being seen in a solitary case. The Direct in situ PCR procedure which was performed in the histologically unconfirmed cases improved the diagnosis with positive results observed in 12/17 (70.6%) cases of Early (p=0.001) and in 12/20 (60%) cases of Suspect Leprosy (p=0.005 indicating the usefulness of the Direct in situ PCR to establish the diagnosis of leprosy in histologically doubtful cases.
