Combination treatment with split-skin-thickness grafting and postsurgical exposure to 308-nm excimer laser in patients with stable focal or segmental vitiligo can lead to fast, cosmetically good, long-lasting results.

Psoriasis is a widespread skin disorder in which nail involvement can be seen in up to two-thirds of those affected. Childhood psoriasis is a distinct entity and the literature focused on nail changes associated with childhood psoriasis is scant. Our objectives were to evaluate the frequency of nail involvement in childhood psoriatic patients, assess the types of nail changes in childhood psoriasis, and compare our clinical findings with the few reports available in the literature. Two hundred and one consecutive new patients with childhood (age < or = 16 years) psoriasis of both sexes were selected for the study of nail changes. The diagnosis of psoriasis was made on clinical grounds. Each patient underwent a thorough dermatologic examination with special attention paid to the nail changes. If a clinical suspicion of fungal infection of the nails existed, further mycologic investigations were performed. We found the prevalence of nail changes to be 37.81% (boys > girls) in children who had psoriasis. Nail pitting was found to be the most common manifestation (61.84%) followed by onycholysis (30.26%), subungual hyperkeratosis (13.16%), and discoloration of the nail plate (7.90%). Nail involvement had no relationship to the type of psoriasis, patient's sex, or duration or extent of disease.

BACKGROUND. Minipunch grafting (MPG) and split-skin grafting (SSG) are common outpatient procedures for the surgical treatment of chronic stable vitiligo. However, there is a paucity of literature comparing the two procedures by the same group of investigators.

Air-borne contact dermatitis caused by Parthenium hysterophorus is a serious problem in India. Patients with this condition have to use corticosteroids regularly in order to maintain clinical remissions, but prolonged usage causes serious side-effects. The weed cannot be eradicated. We have used 3 therapeutic regimens with azathioprine, which led to an effective control with minimal side-effects even when used for long periods. A total of 22 patients (group I) were given 50 mg azathioprine twice a day; 11 patients (group II) received 50 mg azathioprine per day and 300 mg azathioprine every 28 days, and 10 patients (group III) were given 50 mg azathioprine twice a day along with 300 mg azathioprine every 28 days. The duration of treatment varied from 6 months to 3 years. Twenty patients in group I and 9 patients each in groups II and III had complete remission. Nine, 7 and 6 patients in the respective groups needed additional oral betamethasone 1-2 mg per day for brief periods only during the peak season in order to maintain complete remission. One patient in each group had only partial relief. The need for oral betamethasone during the second and the third year was further reduced. One patient each in group I and group II could not continue azathioprine due to the side-effects of the drug.

Patients with parthenium dermatitis are often unresponsive to topical steroids, and immunosuppressive agents may be necessary to reduce their need for systemic corticosteroids. We evaluated the efficacy of methotrexate in parthenium dermatitis. Sixteen patients unresponsive to topical treatment were included after baseline investigations, and treated with oral methotrexate (15 mg/week). Clinical response was monitored using a dermatitis area and severity index (DASI). Seven patients completed >or=6 months' follow-up, and their mean DASI fell to 5, 2.7 and 2.1 at the end of 1, 3 and 6 months respectively, from a baseline score of 10. Only 3/7 patients required oral prednisolone in the initial 2-4 weeks. Side effects were minor, being mainly folliculitis and furuncles. Methotrexate may hence be a useful alternative for patients with severe parthenium dermatitis.

These findings indicate that five weeks appears to be an adequate duration of a therapeutic trial in patients suspected to have cutaneous tuberculosis, with the exception of tuberculids and patients showing minimal clinical activity before treatment. Patients who have not responded by this time are unlikely to do so with further treatment and should have their diagnosis reviewed.

A ten-year-old boy presented with a 2.5-year history of painful shoulder and hip joints, 1.5 years of yellow-brown papules and plaques on the face, flexures and trunk, and 6 months of polyuria and polydipsia. Skin biopsy revealed histological and immunohistochemical features typical of xanthoma disseminatum. Lytic bone lesions were seen in the femur and pelvis and sclerotic changes in the humerus on X-ray. Diabetes insipidus was also diagnosed
