Clinicians always find it difficult to treat hypertrophic scars and keloids. Various treatment modalities are available. Intralesional corticosteroids, topical applications, cryotherapy, surgery, laser therapy, and silicone sheeting are the widely used options. Radiation therapy can also help in cases of recalcitrant keloids. Most recently, pulsed-dye laser has been successfully used to treat keloids and hypertrophic scars. There are no set guidelines for the treatment of keloids. Treatment has to be individualized depending upon the distribution, size, thickness, and consistency of the lesions and association of inflammation. A combination approach to therapy seems to be the best option.

BACKGROUND AND AIMS: Therapy systemic lupus erythematosus (SLE) has been generally discouraging. Methyl-prednisolone pulse therapy has been used for various connective tissue disorders. We used intravenous dexamethasone cyclophosphamide pulse therapy to treat SLE. METHODS: Fourteen patients (10 females and 4 males) between the age of 15-48 years with definite or classical clinical criteria laid by American Rheumatism Association criteria were treated by Dexamethasone-Cyclophosphamide pulse (DCP) therapy at our center. RESULTS: It was possible to induce a complete clinical remission with DCP therapy in most of the patients thereby offering them life free from disease and drugs. The side effects commonly observed with conventional daily dose regimen of corticosteroids were not present or were mild. CONCLUSIONS: Almost all patients had good response after 3-4 pulses to allow them a normal life style. Fever, malar rash and oral ulceration responded early but photosensitivity, discoid rash, alopecia and joint pains took some more time.

BACKGROUND AND AIMS: WHO guidelines classify leprosy patients for therapeutic purposes into paucibacillary (PB) and multibacillary (MB) leprosy based on the number of skin lesions. An alternative system of classification has been in practice in Nepal from 1985 onwards, based on the number of body areas involved in patients of leprosy. We attempted a clinicopathological approach for comparison of these two systems of classification in leprosy patients for their ability to demarcate patients into groups of PB and MB leprosy. MATERIALS AND METHODS: The study included 108 leprosy patients (80 males and 28 females). Complete clinical examination and body charting was carried out in each patient noting the count of skin lesions and the number of body areas involved. Slit skin smears and skin biopsies were taken from an active skin lesion in all patients. RESULTS: On analysis, it was observed that there was good clinicopathological correlation between patients with 5 or <5 skin lesions and 2 or <2 body areas involved. (Clinical 95% and histological 96%) A similar correlation was also observed in the other group of patients with > 5 skin lesions and > 2 body areas involved, (Clinical 94% and histological 96%). There were almost identical numbers of patients represented in these two groups of classification. CONCLUSIONS: Our findings suggest that patients with involvement of 2 or less body areas can be classified as PB leprosy and those with more than 2 body areas involved can be classified as MB leprosy for the purposes of therapy. The study of areas of involvement in leprosy patients not only provides additional patient information but also adds another parameter as a basis for the study of leprosy patients.

BACKGROUND AND AIMS: Altered serum adenosine deaminase (ADA) levels have been recorded in various diseases involving lymphocytes and/or lymphoreticular system including leprosy. The study was planned to evaluate alterations in serum ADA levels, if any, in reactional and non-reactional leprosy. METHODS: Eighty patients of leprosy, comprising 60 patients of non-reactional leprosy and 20 patients of reactional leprosy were studied along with 20 normal healthy controls. Five milliliters of venous blood was collected and ADA levels were estimated by the method of Giusti (1974). RESULTS: There were 54 males and 26 females. The age of the patients ranged from 5 years to 62 years. The duration of leprosy ranged from 15 days to 3 years. The mean serum ADA level in normal controls was 10.31 ± 0.58 u/L. The serum ADA levels were raised in leprosy patients, significantly so in multibacillary patients. The serum ADA levels were higher in patients of leprosy with reaction. CONCLUSIONS: The study showed significantly high serum ADA levels in multibacillary leprosy and this was further increased in patients of leprosy with reaction. This may be because of increased lymphoreticular activity during the reactional phases.

BACKGROUND AND AIMS: Certain dermatological conditions are life-threatening and can cause mortality. The aim of this study is to find out the dermatological diseases leading to death in our indoor patients. METHODS: A record-based retrospective descriptive study of dermatology cases who died during the period of 1995 to 2001. RESULTS: The total number of cases analyzed was thirty-seven. There were 24 males and 13 females. The maximum number of deaths occurred in the age group 61-70. Vesiculobullous disorders were the commonest cause of death, found in 18 cases (48.6%), followed by drug reactions in 5 (13.5%), malignancies in 5 (13.5%) and collagen vascular disease in 2 cases ((5.40%). Pemphigus was the commonest fatal vesiculobullous disorder (13 cases - 35.13%), and toxic epidermal necrolysis the commonest drug reaction (3 cases - 8.10%). CONCLUSION: Area of skin involvement, electrolyte imbalance and septicemia were important factors leading to death in pemphigus and toxic epidermal necrolysis. We advocate that such patients should be managed in burns unit or ICU units.

BACKGROUND: In Asia, HSV seroprevalence studies are sparse and they have recorded lower prevalence of HSV infection, especially HSV-2. AIMS: To ascertain the seroprevalence of HSV-1 and HSV-2 in patients attending a STD clinic in a referral hospital in south India and to compare it with a control group. METHODS: The study included 135 consecutive STD cases having history of ulcerative or non-ulcerative STD in the present or in the past 5 years and 135 age and sex-matched controls. Diagnostic serology was done for HSV-1 and HSV-2 using type specific IgG by indirect immunoassay using ELISA. The results were analyzed utilizing Chi- square test. RESULTS: Amongst 135 STD clinic cases, 106 cases were males and 29 cases were females with male to female ratio of 3.65:1. The mean age was 32.2 years (range 16-65 years). Among study group cases, 112 (82.9%) cases were co-infected with HSV-1 and HSV-2, 11 (8.1%) cases were seropositive for HSV-1 alone and 3 (2.2%) cases were seropositive for HSV-2 alone. In the control group, 112 (82.9%) cases were co-infected with HSV-1 and 2, 12 (9.6%) for HSV-1 alone and 1(0.8%) for HSV-2 alone. Correlation of HSV-1 and HSV-2 serology with various demographic and behavioral factors was statistically insignificant. CONCLUSIONS: Seroprevalence of HSV-1 and HSV-2 in STD clinic cases and control group is high, similar to that recorded in sub-Saharan Africa. Thus, serological studies for HSV-1 and HSV-2 cannot be taken as a marker of sexual behavior in our set of population.

Acne keloidalis nuchae is usually treated with oral antibiotics, local antiseptics or intralesional steroids but with limited success. I assessed the efficacy of diode laser for treating the inflammatory and keloidal papules of acne keloidalis nuchae in two cases. The lesions in both the cases showed about 90 to 95% clearance after 4 treatment sessions at one to one and half month intervals. No new lesions were observed during the follow up period of six months after the last laser treatment. Thus, after clearing bacterial infection, laser hair epilation can be used as the first line of therapy for treating papules of acne keloidalis nuchae. This is the first attempt at treating acne keloidalis nuchae with a diode laser.

Carbamazepine is widely used in the treatment of epilepsy, neuralgic pain, and bipolar affective disorders. Several adverse drug reactions have been described during the course of carbamazepine administration, including exanthemata and hematological reactions. Carbamazepine is one of the common drugs that have been implicated in the etiology of drug hypersensitivity syndrome. A 50-year-old male presented with generalized erythroderma following 10 weeks of ingestion of carbamazepine 200 mg daily for idiopathic epilepsy. His systemic examination was within normal limits. Blood counts revealed marked eosinophilia of 52% (absolute eosinophil count of 10,400 per mm3). Bone marrow aspiration revealed a moderate increase in the eosinophilic series with cells showing normal morphology. The eosinophil counts returned to normal after 2 weeks of oral prednisolone therapy. This case is reported because of its rarity in the Indian medical literature.

Disseminated strongyloidiasis is a rare manifestation in patients on immunosuppressive drugs. We report two cases of fatal disseminated Strongyloides stercoralis infestation. The first was in a patient of pemphigus vulgaris who developed an exacerbation of symptoms, one year after diagnosis and was given intravenous dexamethasone and azathioprine and in the third week of hospitalization developed features of septicemia, respiratory failure and petechial hemorrhages which were proven to be due to disseminated strongyloidiasis. The second patient was diagnosed to have stage IV diffuse large cell type of non-Hodgkin lymphoma and after the second cycle of chemotherapy, developed generalized symptoms of septicemia, respiratory failure, purpuric macules and patches. This was also proven to be disseminated strongyloidiasis.

Pigmented xerodermoid, a rare genodermatosis, presents with clinical features and pathology similar to xeroderma pigmentosum, but at a later age. DNA repair replication is normal, but there is total depression of DNA synthesis after exposure to UV radiation. Two siblings in their teens and a man in his thirties with features of pigmented xerodermoid, e.g. photophobia, freckle-like lesions, keratoses, dryness of skin, and hypo- and hyper-pigmentation, are described. Although classically the onset of pigmented xerodermoid is said to be delayed till third to fourth decade of life, it seems the disease may appear earlier in the tropics. Early diagnosis and management could be life-saving.
