How soon does cutaneous tuberculosis respond to treatment? Implications for a therapeutic test of diagnosis

Background  It is difficult to demonstrate Mycobacterium tuberculosis in smears or biopsies and to grow it in culture in cutaneous tuberculosis because most cases are paucibacillary. A therapeutic trial of antitubercular drugs is frequently used to confirm the diagnosis in difficult cases. Information is lacking on the response to antitubercular therapy in cutaneous tuberculosis; consequently there are no clear guidelines on when to expect a response and also when to abandon a therapeutic trial.

Strawberry gingiva: a distinctive sign in wegener's granulomatosis

A 37-year-old man presented with gingival hyperplasia accompanied by an ulcer on the eyelid, nasal obstruction, ear discharge, and discharging nodules on the cheek and back. An evaluation for infectious diseases and leukemia was negative. During his hospital stay, he had fever and migratory joint pains develop, suggesting a diagnosis of Wegeners granulomatosis, which was confirmed by a strongly positive cytoplasmic antineutrophil cytoplasmic antibody test. He responded promptly to treatment with oral prednisolone and cyclophosphamide. In retrospect, the diagnosis could have been suspected earlier because of the distinctive red, friable, and granular appearance of the gingiva.

Secondary syphilis : a clinicopathologic study

Background. With the resurgence of syphilis in the hiv era, a greater awareness of the clinicopathologic features of the disease is desirable. This report describes and correlates the clinical and histopathologic features of secondary syphilis seen at a teaching hospital in Delhi, India.

Skin Tuberculosis in Children: Learning from India

Cutaneous tuberculosis in children is a major health problem in India. It accounts for about 1.5% of all the cases of extrapulmonary tuberculosis. Scrofuloderma and lupus vulgaris are the two most common forms of tuberculosis. However, the trend in the pattern of cutaneous tuberculosis is changing, as the tuberculid, lichen scrofulosorum, has become more common in recent years. Overall, the clinical patterns are comparable with adults. However, children can have widespread and severe involvement because many unusual and uncommon patterns are known to occur in children. Underlying systemic involvement is more common in children, compared with adults.

Phaeohyphomycosis caused by Exophiala spinifera in India.

The second case of phaeohyphomycosis due to Exophiala spinifera in India has been diagnosed 46 years after the initial case. The present case involved a 12-year-old female patient with no known immunocompromising conditions. She presented with multiple verrucous, well-defined plaques encompassing phaeohyphomycotic lesions of varying sizes on her face, chest, arms and thighs. Lymph node involvement in dissemination was confirmed by demonstrating pigmented fungal elements in histopathology of the left axillary node. The infection responded positively to prolonged administration of itraconazole. The original case involved a young boy and was similarly disseminated but was more severe, with bone involvement, and had a fatal outcome. It is likely that other such cases have occurred in the intervening time but have not been reported.

The psychosocial impact of vitiligo in Indian patients

BACKGROUND Vitiligo has a special significance in Indian patients both because depigmentation is obvious on darker skin and the enormous stigma associated with the disease in the culture. AIMS This study was carried out to determine the beliefs about causation, aspects of the disease that cause concern, medical, and psychosocial needs of the patients, expectation from treatment and from the treating physician, and effects of disease on the patients life. METHODS Semi-structured interviews were conducted in 50 patients with vitiligo. Purposive sampling was used to select subjects for the study. Each interview was recorded on an audio-cassette and transcripts were analyzed to identify significant issues and concerns. RESULTS Patients had a range of concerns regarding their disease such as physical appearance, progression of white patches onto exposed skin and the whole body, ostracism, social restriction, dietary restrictions, difficulty in getting jobs, and they considered it to be a significant barrier to getting married. The condition was perceived to be a serious illness. Stigma and suicidal ideation was reported. While there were several misconceptions about the cause of vitiligo, most patients did not think their disease was contagious, heritable or related to leprosy. Multiple medical consultations were frequent. Complete repigmentation was strongly desired, but a lesser degree of repigmentation was acceptable if progression of disease could be arrested. The problems were perceived to be more severe in women. The disease imposed a significant financial burden. CONCLUSION Addressing psychosocial factors is an important aspect of the management of vitiligo, particularly in patients from communities where the disease is greatly stigmatizing.

A two-step schedule for the treatment of actinomycotic mycetomas.

Actinomycotic mycetomas usually respond slowly to treatment with antibiotics. In an attempt to hasten clinical resolution, we used a 2-step regimen consisting of an intensive phase of therapy with penicillin, gentamycin and co-trimoxazole for 5-7 weeks, followed by maintenance therapy with amoxicillin and co-trimoxazole. Seven patients were treated, all of whom showed significant reduction in discharge and swelling after the intensive phase. Maintenance therapy was continued for 2-5 months after the lesions became completely inactive. Five patients completed maintenance therapy, which was given for 6-16 months (mean 10.7 months), and remained free of disease during a mean post-treatment follow-up period of 6.4 months. The other 2 patients also responded satisfactorily and continue to receive maintenance therapy. Side-effects necessitating a modification of the treatment schedule occurred in 2 patients but reversed on discontinuation of the drugs responsible. This treatment schedule produces a rapid clinical response during the initial, intensive phase and promotes compliance with the longer maintenance phase of treatment necessary to achieve a complete cure.

Segmental vitiligo: A randomized controlled trial to evaluate efficacy and safety of 0.1% tacrolimus ointment vs 0.05% fluticasone propionate cream

BACKGROUND Segmental vitiligo is a small subset of vitiligo which responds very well to surgical therapy, but the role of medical treatment is not very well defined. AIM To compare the efficacy and safety of 0.1% tacrolimus ointment versus 0.05% fluticasone propionate cream in patients of segmental vitiligo. METHODS A randomized control trial was conducted in a tertiary care hospital on 60 consecutive patients with segmental vitiligo. Patients with segmental vitiligo exclusively or along with focal vitiligo, untreated or had not taken any topical treatment in previous 1 month or systemic treatment in previous 2 months, from May 2005 to January 2007, were block randomized into two groups. Children <5 years, pregnant and lactating women, and patients with known hypersensitivity to either drug and with associated multiple lesions of vitiligo were excluded. Group A (n = 29) patients were treated with tacrolimus 0.1% ointment twice daily and group B (n = 31) patients were treated with 0.05% of fluticasone cream once daily for 6 months. Response and side effects were recorded clinically and by photographic comparison. RESULTS Nineteen patients treated with tacrolimus and 21 patients treated with fluticasone completed the treatment with median repigmentation of 15% and 5%, respectively, at 6 months (P = 0.38). Transient side effects limited to the application site were observed. CONCLUSIONS Both tacrolimus and fluticasone propionate produce variable but overall unsatisfactory repigmentation in segmental vitiligo.

A modified two-step treatment for actinomycetoma.

BACKGROUND Combination antibiotic regimens are effective in the treatment of actinomycetoma but many treatment schedules require supervised parenteral therapy for prolonged periods. We describe a schedule that includes parenteral medication in an initial, short phase followed by a longer phase of oral medication. METHODS Sixteen patients with clinically diagnosed mycetoma, who did not show any evidence of a fungal etiology, were treated presumptively for actinomycetoma. Evidence of actinomycotic infection was found on microscopy of granules / discharge and / or histopathological examination in eight (50%) patients. The treatment consisted of an intensive phase (Step 1) with gentamicin, 80 mg twice daily, intravenously and cotrimoxazole, 320/1600 mg twice daily orally for four weeks. This was followed by a maintenance phase with cotrimoxazole and doxycycline, 100 mg twice daily till all sinuses healed completely. The treatment was continued for 5-6 months. RESULTS Treatment response was assessed monthly. At the end of the intensive phase, there was a significant improvement in all 16 patients. Nine patients who continued the maintenance phase of the regimen had complete healing of sinuses with marked reductions in swelling and induration in 2.4 +/- 1.7 months. Maintenance treatment was continued for a mean of 9.1 +/- 4.3 months in these patients. Six patients have remained free of disease activity during a follow-up period of 11.1 +/- 4.2 months after treatment was stopped. Two patients developed leucopenia and thrombocytopenia necessitating withdrawal of cotrimoxazole. CONCLUSION This regimen was effective in treating actinomycetoma. The short duration of the phase requiring parenteral therapy makes it convenient to administer.

Parthenium dermatitis presenting as photosensitive lichenoid eruption. A new clinical variant.

Parthenium hysterophorus is the commonest cause of airborne contact dermatitis (ABCD) in India. The disease usually manifests as itchy erythematous, papular, papulovesicular and plaque lesions on exposed areas of the body. Rarely, however, the disease may present as actinic reticuloid or photocontact dermatitis. We have observed a different clinical variant of this disease where certain patients with Parthenium dermatitis have presented with discrete, flat, violaceous papules and plaques on exposed areas of the body closely simulating photosensitive lichenoid eruption. We had 8 patients, 6 males and 2 females between 30 and 62 years of age, with itchy, violaceous, papules and plaques on the face, neck, ears, upper chest and dorsa of the hands for 6 months to 6.5 years. Four of these patients had a history of improvement of the lesions up to 30% in winter and aggravation of lesions on exposure to sunlight. There was no personal or family history of atopy. Cutaneous examination in all patients revealed multiple flat, violaceous, mildly erythematous papules and plaques on the forehead, sides and nape of neck, ears, ‘V’ area of the chest, and extensor aspects of the forearms and hands. Skin biopsies from these lesions showed features of chronic non‐specific dermatitis. Patch testing with standardized plant antigens showed a positive patch test reaction to Parthenium hysterophorus in all patients, with a titre of contact hypersensitivity (TCH) varying from undiluted to 1 : 100. We conclude that Parthenium dermatitis may occasionally present with lesions very similar to the lesions of photosensitive lichenoid eruption in morphology and distribution. This clinical presentation of Parthenium dermatitis needs to be recognized to avoid misdiagnosis.
