A total of 14,342 patients with skin diseases who had attended either the National University of Malaysia skin clinic or a private dermatological office were analysed. Five hundred and thirty-four cases (3.7%) had atopic eczema, the prevalence being highest among the Malays (4.3%). The prevalence of atopic eczema among clinic attenders is lower in all three major Malaysian races when compared with studies from England.
Skin scrapings taken from toe spaces of 200 healthy volunteers and from toe webs and groins of 150 pediatric patients were cultured for Candida albicans using the serum germ-tube test. The results showed that Candida albicans can be isolated in about 15% of normal toe spaces and 14% of children with normal groins. Although Candida albicans can be found in various grades of athlete's foot and also in some abnormal groins, we believe that it is not necessarily responsible for these conditions and is often present at these sites only as a saprophyte.

Oral administration of an aromatic retinoid has a marked beneficial effect on psoriasis and does not produce significant changes in liver function or the blood count when given at a dose of 25 mgm three times a day for six weeks. This effect does not occur unless the drug has produced dermatological side-effects and this may inhibit its future acceptance but the present findings indicate that, at least in the less developed parts of the world where many Western treatments are unacceptable for various reasons, oral retinoids are a useful and relatively safe addition to the present range of medications available for psoriasis.
