Ultraviolet-A1 phototherapy in Asian skin: A review of 159 cases in Singapore.

BACKGROUND: Ultraviolet-A1 phototherapy has been used to treat many inflammatory dermatoses. AIMS: To determine the efficacy and safety of ultraviolet-A1 phototherapy in Asian skin. MATERIALS AND METHODS: We performed a review of records of patients undergoing ultraviolet-A1 phototherapy at our dermatology unit in Singapore from January 2007 to January 2011. Their electronic medical records were reviewed and a standardized questionnaire was filled up for data collection and tabulation. Chi-square or Fisher's exact tests were used to compare the difference in response between various groups for each characteristic. P value of < 0.05 was considered statistically significant. RESULTS: Our study comprised of 159 patients, of which 103 were patients with hand and foot eczema, 21 with atopic dermatitis, 17 with scleroderma and the remaining with miscellaneous dermatoses. Of these patients, 47.6% of patients with hand and feet eczema had good response after 10 sessions, which increased to 75% after 20 sessions and to 84.6% after 30 sessions. After 10 sessions, 47.6% of patients with atopic dermatitis had good response, which increased to 66.7% after 20 sessions. After 30 sessions, all the three remaining patients with atopic dermatitis experienced good response. For patients with scleroderma, only 11.8 and 10% had good response after 10 and 20 sessions, respectively, which increased to 40% after 30 sessions. LIMITATIONS: Limitations of our study include its retrospective design and, consequently, the lack of standardized treatment protocol, as well as subjective assessment in terms of clinical improvement. CONCLUSIONS: Ultraviolet-A1 phototherapy appears to be efficacious for the treatment of hand and foot eczema as well as atopic dermatitis. However, in patients with scleroderma, the response was partial and needed a longer duration of treatment.

Dermatoses due to Arabic cultural and traditional practices.

A number of social and cultural practices are prevalent in the Middle-East celebrating various occasions or to treat health conditions. These often result in dermatoses that are unfamiliar and confusing to dermatologists outside this region. This paper reviews skin manifestations emanating from traditional and ritual practices in Arab countries, particularly those from Saudi Arabia.

Cutaneous sarcoidosis: clinical profile of 23 Indian patients.

BACKGROUND: Sarcoidosis is a multisystem disease of undetermined etiology. Indian studies on cutaneous sarcoidosis are not many and mainly comprise case reports. AIMS: This retrospective study was carried out to assess the clinical profile of sarcoidosis patients presenting with cutaneous lesions. METHODS: All histopathologically proven cases of cutaneous sarcoidosis seen consecutively between 1999 and 2004 were studied. Their age, sex, presenting features, evolution of disease and laboratory parameters were analyzed. RESULTS: A total of 23 patients (F:M 15:8) between 31 to 78 years (mean 44.3 years) of age had the mean duration of skin lesions of 1.4 years. Six patients had one to four lesions; two patients each had scar sarcoidosis and angiolupoid and one patient each had recurrent erythema nodosum, leg lymphedema and subcutaneous sarcoidosis. Others showed combination of papules, nodules, plaques and psoriasiform lesions. Peripheral lymph nodes were involved in two patients. Among 10 patients of pulmonary involvement, three had become symptomatic four months to four years after the cutaneous lesions. Routine laboratory investigations including serum calcium estimation were normal in all cases. Serum angiotensin-converting enzyme levels were raised in 3 out of 6 patients. Asymptomatic lytic lesions of digital bones were detected in hand X-ray of one patient. CONCLUSION: Skin lesions of sarcoidosis are like the tip of an iceberg indicating more changes in other organs. The symptomatology and abnormal laboratory results do not necessarily correlate with the severity of cutaneous involvement in general.

Stigma experience in skin disorders: an Indian perspective.

Dermatologic disorders generally have a major impact on patients' daily activities, psychologic and emotional state, and social relationships. The intensity of impact of skin disease on an individual person is extremely variable, however, and depends on natural history of the disorder; the patient's demographic characteristics, personality, character, and value; the patient's life situation; and the attitudes of society. Social stigma toward dermatologic disorders in the Indian society is quite widespread, especially toward leprosy. Dermatologists are expected to consider quality of life issues along with social aspects, nature of disorder, efficacy, and tolerability of various therapeutic options to optimize relief and comfort to their patient.

Skin and treponemal diseases among Asian domestic house-helpers in northern Saudi Arabia.

BACKGROUND: Asian domestic house-helpers in Saudi Arabia come from a different socioeconomic setting with a different disease pattern from that of their host country. This study reports the incidence of skin and treponemal diseases in this group seen at a referral hospital in northern Saudi Arabia. METHODS: The study was based on the analysis of the dermatologic and serologic examinations of 1520 domestic house-helpers during resident permit issue, and a retrospective study of clinical records of house-helpers with skin disorders. RESULTS: Routine examination revealed significant skin disease in 374 (24.6%) individuals, and the disease was transmissible in 126 (8.3%). Treponemal infection (5, 0.3%) and leprosy (1, 0.07%) were seen. Hand dermatitis and chicken pox were the most common causes of hospital attendance. Psychologic skin disorders included three cases of neurotic excoriations, two cases of delusion of parasitosis, and a case of dermatitis artefacta. CONCLUSIONS: The prevalence of transmissible skin diseases in Asian domestic house-helpers is low compared with that in their home countries. Excluding individuals with stigmata of atopic dermatitis from employment as house-helpers, adequate counselling will reduce the incidence of hand dermatitis and psychologic skin disorders. There is a need for continuous surveillance to prevent the introduction of skin diseases not normally seen in the native population.
