A trial to determine the role of placental extract in the treatment of chronic non-healing wounds.

OBJECTIVE: To investigate the effect of topical placental extract in the treatment of non-healing wounds. METHOD: One hundred patients attending the wound clinic at University Hospital, Varanasi, India, with wounds of more than six weeks' duration were recruited. Fifty patients were treated with placental extract, and 50 were controls. Wound biopsy and swab culture and sensitivity were performed and the area surrounding the wound was X-rayed. Wound size was measured and the rate of epithelialisation assessed at weekly follow-ups. In nine cases biopsies were repeated after two weeks of treatment and sent for histopathological examination, including angiogenesis. RESULTS: Thirty patients dropped out, leaving 40 cases in the treatment group and 30 in the control group. Over an eight-week period, 27 patients (67.5%) in the treatment group showed more than 50% epithelialisation, compared with only seven patients (23.3%) in the control group. CONCLUSION: Placental extract has a beneficial role to play as a topical agent in the management of chronic non-healing wounds.

Management of plantar ulcers in Hansen's disease.

Plantar ulcers occur in patients with Hansen's disease not because of the disease but because of its neuropathic effects on the skin over the feet. This enhances the risk of trauma to patients' feet, leading to the development of ulcers. This short article reviews the current management of leprosy on the basis of World Health Organization guidelines and the complexities of plantar ulceration in such patients. A guide to its management and prevention is also discussed.

Topical therapy for psoriasis with the use of augmented betamethasone and calcipotriene on alternate weeks.

BACKGROUND: Topical corticosteroids, commonly used for psoriasis, show diminished response on continuous use. OBJECTIVE: We tested efficacy of topical corticosteroid and calcipotriene used on alternate weeks versus daily corticosteroid in patients with psoriasis. METHODS: In a randomized, observer-blind design, the experimental group of 25 patients with stable plaque psoriasis received augmented betamethasone dipropionate 0.05% cream once daily in the first and third weeks and calcipotriene 0.005% ointment twice daily in the second and fourth weeks. The control group of 27 patients received augmented betamethasone once daily for 4 weeks. RESULTS: The experimental regimen was more effective than the control regimen as evidenced by (1) more patients with at least a 90% reduction in Psoriasis Area and Severity Index (PASI) score (difference 49.5%, 95% confidence interval [CI], 26.1%-72.9%, P <. 001), (2) lower PASI after 2 weeks (P < or =.04), and (3) greater percentage reduction in PASI after 2 and 4 weeks (difference 23.1% [CI, 11.1%-35.1%] and 46.4% [28.9%-63.8%], respectively; P <.001). The study had power of 93.7%. No patient had skin irritation. CONCLUSION: Use of augmented betamethasone and calcipotriene on alternate weeks is more effective than daily corticosteroid and represents a novel strategy for treating psoriasis.

A clinico-epidemiological profile of non-healing wounds in an Indian hospital.

One hundred patients with non-healing wounds of more than six weeks' duration were studied for clinico-epidemiological factors and their correlation with healing time. The majority of subjects were aged 30-59 years; those aged 50 and over had significantly delayed healing. Most of the subjects were farmers and physical labourers. Leprosy was the most common cause of non-healing wounds, followed by diabetes, trauma and venous ulcers; the lower limbs were the most common site of involvement. Diabetic wounds were more common in those aged 40 years and above. Diabetic wounds were slower to heal than others. The time to healing was calculated from the day subjects received treatment advice at the wound clinic. Seventy-five of the study group were included for calculation of healing time. The others were lost to follow-up or excluded for other reasons.

Tachyphylaxis to histamine-induced wheal suppression by topical 0.05% clobetasol propionate in normal versus croton oil-induced dermatitic skin.

BACKGROUND: Patients often tell about reduced effectiveness of topical steroids on repeated use. Tachyphylaxis to these agents has been demonstrated in humans for vasoconstriction and histamine-induced wheal suppression in normal skin, but not in diseased skin. Relevance of these data to diseased skin is not clear. Further, the clinical impression does not appear to match tachyphylaxis shown in normal skin with regard to the time course. OBJECTIVES: To examine whether tachyphylaxis to histamine-induced wheal suppression by a topical steroid occurs in dermatitic skin and to determine its time course vis-à-vis normal skin. METHODS: Pharmacodynamic response to 0.05% clobetasol propionate applied daily under occlusion was measured by histamine-induced wheal suppression assay in 10 individuals. This test was performed on a steroid-treated normal site, on a steroid-treated site where dermatitis was induced by occlusive application of 40% croton oil, and on a vehicle-treated site in each individual at different intervals up to 14 days. RESULTS: Suppression of wheal volume started from second day in steroid-treated sites. There was significant difference in the wheal volume in steroid treated normal vs. dermatitic sites from day 2 to day 10. Maximum wheal suppression occurred earlier in dermatitic skin (day 4 vs. day 6). After this, the volume of wheal started increasing and became equal to control (complete tolerance) on 12th day in dermatitic skin and on 14th day in normal skin. CONCLUSIONS: Time courses of tachyphylaxis to the action of 0.05% clobetasol propionate were significantly different in normal skin and dermatitic skin. Complete tolerance occurred earlier in dermatitic skin compared to normal skin.

Epidemiology of leprosy in tribals of Adhaura plateau.

A door to door survey was carried out in the Adhaura plateau of Bihar, to find out the magnitude of leprosy problems in that area. Out of a total of 7,521 persons, mostly tribals, 5,476 were examined giving a coverage of 72.8%. Prevalence rate of leprosy was 20.6%/1000 population. Maximum prevalence was seen in the age group of 55 and above. The disease was more common in males and in the literate and educated group. The ratio of tuberculoid was 57.5%, borderline 29.0% and lepromatous 10.0%, indeterminate type constituted 3.5%. The population had a poor nutritional status with caloric intake of 1471 cal per day.
