摘要:

AbstractAt the National Skin Centre, 74,589 new attendances were seen from 1989 to 1990. The M:F ratio was 1:1. The majority of the patients belonged to the 20–39 year age groups (40%). Frequencies of psoriasis (20.4%) and alopecia (17.2%) were higher among Indians; exfoliative dermatitis was higher among Malays (19.72%); and insect bites were higher among Chinese (87%) [P<0.05] compared with ethnic distribution (9.9%, 7.6%, and 77.2% respectively) of NSC patient population. Dermatitis (34.2%) and acne (10.9%) were the most common skin disorders seen. The more common dermatoses seen in 1989/90 differ slightly from those reported in 1950s and 1980s; however, the frequencies of contact dermatitis, fungal infection, and insect bite reactions of 5.8%, 10.9%, and 7.6%, respectively, in 1980 have decreased to 4.7%, 5.4%, and 2.3%, respectively, in 1989/90. There was no seasonal variation in the frequency of various dermatoses except for psoriasis, which was more prevalent during the first quarters of 1989 and 1990. Our results showed that the pattern of skin diseases in Singapore is slowly approximating that of developed countries. The changes in the pattern of skin diseases are probably due to improved economic status, better education and hygiene, ready availability of dermatology services, as well as changes in occupational and environmental contactants over the last decad

摘要:

AbstractIn the nations of the developing world, the incidence of skin disease is especially affected by geography. While most studies focus on the tropics, this report records the pattern of skin diseases encountered in a South American mountain city. Among 1277 patients examined, the noninfectious dermatoses predominated.

摘要:

AbstractA retrospective study of 11,802 patient records with cutaneous leishmaniasis in Riyadh region was conducted during the period 1987 to 1990. The following findings resulted from the study. The incidence rate declined from 244.2 to 106.5 per 100,000 population. The infection was mainly among non‐Saudi men in their working years. The Saudis represented 33% of the total number of patients. The Saudi patients were mainly young, below 15 years of age, with almost equal men/women distribution. The non‐Saudis were found to have more multiple lesions; 65% of them had three or more lesions compared with 10% in Saudis. The lesions were mainly on the exposed parts of the body such as the face (20%), neck (3.3%), upper limbs (23.3%), and lower limbs (15%). Agricultural areas such as Riyadh vicinity, Al‐Kharj, Shagraa, and Al‐Koweeya showed consistently the highest foci of infections. The infections were highest in winter and lowest in

摘要:

AbstractA 16‐year‐old man had long‐standing diffuse cutaneous leishmaniasis with the following characteristics: diffuse infiltrated lesions rich in amastigotes, absence of mucosal involvement, and lack of parasite‐specific cell‐mediated immune response.In situidentification ofLeishmania mexicanaamazonensis was achieved by the use of monoclonal antibodies. Clinically, as an atypical finding there was deep and extensive ulceration in the lower limbs. Histologically, an atypical characteristic was the presence of a high number of eos‐inophils in the infiltrate predominantly in the ulcerated lesion. Ultrastructurally, parasitized and lysed eosinophils with dispersion of their granules were seen in the vicinity of parasitized or lysed
