Clinico-epidemiological Study of Disability Due to Leprosy at the Time of Diagnosis among Patients Attending a Tertiary Care Institution.

BACKGROUND: With the declared elimination of leprosy as a public health problem, the World Health Organization has shifted the focus on the disabilities and deformities associated with leprosy. AIMS: The aim was to study the Grade 1 and Grade 2 disability among newly diagnosed leprosy patients. MATERIALS AND METHODS: All newly diagnosed leprosy patients attending the Outpatient Department of Government Medical College, Kozhikode, from January 1, 2013 to December 31, 2013 were included in the study and the Grade 1 and Grade 2 disabilities observed were analyzed. RESULTS: During the 1-year period, 76 patients were diagnosed to have leprosy. Grade 1 and Grade 2 disabilities were noted in 31.6% and 17.1%, respectively. Major factors identified as risk for leprosy disability at the time of diagnosis were age >45 years, >5 skin lesions, ≥2 thickened peripheral nerve trunks, pure neuritic and borderline tuberculoid spectra of leprosy. LIMITATION: As the study was conducted in a tertiary care center, it does not perfectly indicate the status in the community. CONCLUSION: Disability noted in nearly 50% of leprosy cases at the time of diagnosis highlights the need to improve the effectivity of existing health-care system in early case detection and timely referral. In addition, it underscores the need to educate the affected regarding protective eye, foot, and hand care, so that progression to Grade 2 disability can be prevented.

Predictors of disease severity in drug reaction with eosinophilia and systemic symptoms.

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms is an outcome of a complex interaction between specific drugs, certain herpesviruse types and the immune system of the affected individual and is characterized by an unpredictable course and recurrent flares even after withdrawal of the offending drug and administration of systemic steroids. AIMS: To identify the predictors of disease severity in drug reaction with eosinophilia and systemic symptoms. METHODS: After obtaining ethical clearance from the institutional ethics committee and a written informed consent from individual study participant, the first hundred patients who required inpatient care in Government Medical College, Kozhikode with drug reaction with eosinophilia and systemic symptoms from January 1st 2011 were included in this study aimed to identify the predictors of disease severity in drug reaction with eosinophilia and systemic symptoms. RESULTS: Male-to-female ratio of the study group was 0.8:1. The presence of atypical cells in peripheral smear and advanced age were found to be predictors of disease severity in drug reaction with eosinophilia and systemic symptoms, whereas, sex, facial erythema and edema and absolute eosinophil count were found not to be predictors of the same. LIMITATIONS: The main limitation of this study was our inability to assess the role of human leukocyte antigen (HLA) association and herpes virus reactivation in disease severity in drug reaction with eosinophilia and systemic symptoms. This study was also not designed to evaluate the response to treatment given and the mortality caused by drug reaction with eosinophilia and systemic symptoms. CONCLUSIONS: Studies on the predictors of severity in drug reaction with eosinophilia and systemic symptoms in different population groups may enable us to identify the warning signs and help to formulate the standard therapeutic guidelines.

Methotrexate iontophoresis versus coal tar ointment in palmoplantar psoriasis: A pilot study.

BACKGROUND: Palmoplantar psoriasis is often disabling and refractory to conventional therapy. Systemic drugs are indicated in its severe form, but side effects are a concern with their use. Methotrexate is one such systemic drug which is effective and cheap. To reduce systemic toxicity, methotrexate has been tried topically but results have been inconsistent due to poor drug penetration into the skin by passive diffusion. Iontophoresis may enhance its absorption and efficacy. AIM: To evaluate the efficacy and safety of topical methotrexate iontophoresis in comparison with coal tar ointment in the treatment of palmoplantar psoriasis. METHODS: Thirty-one patients with palmar and/or plantar psoriasis were selected for the study and 28 patients completed it. The side having more severe involvement was treated while the other palm/sole served as a control. Iontophoresis using methotrexate solution was carried out on the study palm/sole with the injectable preparation of methotrexate (50 mg/2 ml) once a week for the first 4 weeks and subsequently every two weeks, for a total of six sittings. The control palm/sole was treated with coal tar ointment on other days. Erythema, scaling, induration and fissuring scores were noted in both groups before and after treatment. RESULTS: Both study and control groups showed decreases in scores but the reduction was more in the study group, the difference being statistically significant. LIMITATIONS: Drawbacks of our study include the small sample size and the lack of follow-up. The study and control arms were not exactly matched and the study was not blinded. CONCLUSION: Methotrexate iontophoresis was safe and more effective than coal tar ointmentin palmoplantarpsoriasis.

Leprosy: Trophic Skin Ulcers.

Leprosy is a chronic infectious disease caused by Mycobacterium leprae. Approximately 30% of patients with leprosy develop nerve damage. Trophic, or neuropathic, ulcer is a common complication of an anesthetic foot. The term plantar, trophic, or perforating ulcer was introduced in 1959. It was defined as a chronic ulceration of the anesthetic foot, situated in well-defined areas overlying bony prominences, resistant to local and/or systemic therapy, and characterized by a marked tendency to recur. It is responsible for much of the morbidity associated with leprosy.

Pyoderma gangrenosum: A clinico-epidemiological study.

BACKGROUND: Pyoderma gangrenosum is a neutrophilic dermatosis of unknown etiology, with inconstant systemic associations and a variable prognosis. AIMS: To study the clinical features and systemic associations of pyoderma gangrenosum and its response to treatment. METHODS: All patients diagnosed to have pyoderma gangrenosum at the dermatology department of the Government Medical College, Kozhikode, from January 01, 2005 to December 31, 2014 were included in this prospective study. RESULTS: During the 10-year study period, 61 patients were diagnosed to have pyoderma gangrenosum. A male predilection was noted. The most common clinical type was ulcerative pyoderma gangrenosum (90.2%). More than 60% of patients had lesions confined to the legs; 78.7% had a single lesion and 27.9% had systemic associations. Most patients required systemic steroids. Patients with disease resistant to steroid therapy were treated with intravenous immunoglobulin G and split-thickness skin grafts under immunosuppression induced by dexamethasone pulse therapy. All except one patient attained complete disease resolution. LIMITATIONS: The main limitation of our study was the small sample size. CONCLUSIONS: The male predilection documented by us was contrary to most previous studies. We found split-thickness skin graft to be a useful option in resistant cases. More prospective studies may enable the formulation of better diagnostic criteria for pyoderma gangrenosum and improve its management.

Drug reaction with eosinophilia and systemic symptoms (DRESS): A histopathology based analysis.

BACKGROUND: The data on the histology of cutaneous lesions of drug reaction with eosinophilia and systemic symptoms (DRESS) is limited. AIMS: To study the histopathology of cutaneous lesions of drug reaction with eosinophilia and systemic symptoms (DRESS) and to identify any features with diagnostic or prognostic significance. METHODS: All patients admitted to the dermatology ward of government medical college, Kozhikode from January 1, 2014 to December 31, 2014 with probable or definite DRESS as per the RegiSCAR scoring system and who were willing to undergo skin biopsy were included in this prospective study. RESULTS: The study population comprised of nine patients. The consistent histological finding documented was the predominantly lymphocytic dermal inflammatory infiltrate. Four of the five patients whose histology revealed focal interface dermatitis and keratinocyte vacuolation with or without apoptotic keratinocytes, had elevated liver transaminases. Tissue eosinophilia was associated with disease flares. The presence of atypical lymphocytes in peripheral smear and histological evidence of dense dermal inflammatory infiltrate showed an association with hepatic involvement. LIMITATIONS: The main limitations of our study were the small sample size and our inability to carry out a detailed immunohistochemistry work-up. CONCLUSIONS: In the appropriate setting, varying combinations of epidermal hyperplasia, spongiosis, parakeratosis and individually necrotic keratinocytes in the background of lymphocyte predominant dermal infiltrate (with some atypia) favor a diagnosis of drug reaction with eosinophilia and systemic symptoms. Female sex, the presence of atypical lymphocytes in peripheral smear, dense dermal inflammatory infiltrate, tissue eosinophilia and interface dermatitis with or without keratinocyte necrosis was associated with a poor prognosis.

Childhood leprosy: a retrospective descriptive study from Government Medical College, Kozhikode, Kerala, India.

OBJECTIVE: To assess the profile and describe the clinical presentations and complications of childhood leprosy in a tertiary care hospital in North Kerala, South India during 2003-2012 and to analyse any change in the age-sex profile and the clinical pattern of leprosy in children below the age of 15 years over the 10-year study period. DESIGN: A retrospective descriptive study of children less than 15 years of age diagnosed with leprosy and registered for treatment in a tertiary care institution from 2003 to 2012. Demographic, clinical, investigative and treatment data were collected using a pre-set proforma. RESULTS: 138 (12.1%) of the total 1143 leprosy cases registered for treatment during the 10-year period were below 15 years of age. The 10-year study period witnessed a statistically insignificant decrease in the new childhood leprosy cases registered for treatment in our tertiary care institution. The majority of cases belonged to the 6-12 year age group (61.6%) with a male predominance. Borderline tuberculoid (BT) was the commonest clinical type (65.9%) followed by indeterminate leprosy (18.8%); 101 patients required paucibacillary (PB) and 37 needed multibacillary (MB) treatment. The number of patients requiring MB treatment showed a statistically significant increase and there was a significant decline in number of cases requiring PB treatment. During the entire study period no Type 2 lepra reaction was documented in patients below Hema 15 years and only two patients manifested Type 1 reaction. Ten (7.2%) out of the 138 patients were cases of relapse. There was a clear female predilection among relapse cases with the majority belonging to the adolescent age. CONCLUSIONS: Childhood leprosy still contributes to a significant proportion of the total case load denoting the continuing active horizontal transmission of leprosy. The rise in number of patients with more extensive disease in the background of declining disease prevalence is suggestive of the delay in diagnosis and treatment. A high relapse rate noted in the present study may be due to incorrect classification and treatment of MB as PB leprosy which in turn might have resulted in treatment failure due to inadequate treatment.

Drug reaction with eosinophilia and systemic symptoms: observations from a tertiary care institution.

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe drug reaction which can mimic a viral infection, an autoimmune disease or a neoplastic disease. AIMS: To study the clinical and epidemiological aspects of DRESS and to identify the precipitating drugs. METHODS: All patients admitted to the dermatology ward of our tertiary care hospital from 1 st October 2010 to 30 th September 2013 with probable or definite DRESS as per the RegiSCAR scoring system were included in this prospective study. The clinical manifestations observed in the study population were studied and the common offending drugs were identified. RESULTS: During the 3 year study period, 26 patients fulfilled criteria for probable or definite DRESS. In more than 50% of cases, the culprit drug was phenytoin. Most common symptoms observed were fever, rash and facial edema. Liver was the most common internal organ affected. Most of the patients responded to withdrawal of the drug and administration of steroids for 3-6 weeks. One patient with dapsone-induced DRESS died. CONCLUSIONS: Intense facial erythema and edema and an elevated eosinophil count were not found to be bad prognostic factors. In most instances the flare ups during the course of the disease could be managed with a slower tapering of steroids. More prospective studies on DRESS are required to assess the prognostic factors and to formulate better diagnostic criteria.

Hypnotherapy: A Useful Adjunctive Therapeutic Modality in Hansen's Disease.

Hypnotherapy is a useful adjunctive psychotherapeutic procedure used in various conditions such as pain disorders, atopic dermatitis, and alopecia areata. However, it is less utilized in the field of dermatology. Only limited data exist on its role in the management of various skin diseases. There is dearth of literature on the role of hypnotherapy in Hansen's disease (HD). We report two cases of HD, one with very resistant neuralgia and the other with recurrent erythema nodosum leprosum (ENL). Both the patients were assessed using hospital anxiety and depression scale, dermatology life quality index and the neuralgia was assessed using the visual analog scale. Three sessions of hypnotherapy were given to both the patients. There was dramatic improvement in the incidence of ENL and neuralgia and we could rapidly reduce the dose of drugs used for both conditions.

Pancytopenia due to lepromatous involvement of the bone marrow: successful treatment with multidrug therapy.

Leprosy is a chronic infectious disease with a wide spectrum of signs and symptoms depending on the ability of the host's immune system to resist the infection. The disease is frequently associated with sensory loss in skin lesions and damage in peripheral nerve trunks leading to nerve function impairment. In lepromatous leprosy, the immune system offers no protection against the multiplying bacilli and this results in heavy infiltration of the internal organs. We report a case of florid lepromatous leprosy with bone marrow suppression due to the disease, presenting with anemia, leukocytopenia and thrombocytopenia. The hematological abnormalities were fully reversed by mutidrug therapy for leprosy. We suggest that infiltration of the bone marrow by Mycobacterium leprae can cause pancytopenia, which can be cured by treatment of the leprosy alone.
