Advised best practice for the use of emollients in eczema and other dry skin conditions.

The recent Dermatological Care Working Group report highlighted important deficiencies in the dermatology service in the UK and recommended that care should move closer to the patient. The report stated that 'expert patients' could become 'sharers in their care' and are best placed to improve their own self management. One area that could benefit greatly from increased patient education and participation is the use of emollients. Emollients are frequently prescribed for patients with eczema and other dry skin conditions. Although the benefits of emollient therapy are widely accepted, prescribing practices vary considerably, often according to physicians' individual preferences. Patients can receive confusing or conflicting treatment advice, leading to frustration, non-compliance, and difficulty in following an effective regimen. To promote the effective use of emollients it is important for patients and health professionals to understand the functions of the skin and the principles of emollient use and application. We propose a set of simple guidelines for emollient therapy in eczema care to improve day-to-day management by health professionals in the community and to promote consistent practices by patients. These guidelines form the ABC dry skin and eczema management programme supported by the National Eczema Society and accredited by the British Skin Foundation.

The effects of spiramycin and/or scaling on advanced periodontitis in humans.

It has long been questioned whether antibiotics, used as a supplement to traditional therapy, provide any lasting benefit in the treatment of chronic periodontitis. This study was designed to evaluate Spiramycin as an adjunct to scaling and root planing in the treatment of advanced chronic periodontitis. In total, 193 patients with advanced periodontitis were recruited in seven centres using selection criteria previously described. After undergoing thorough scaling and root planing, all patients randomly received either Spiramycin, 1,500,000 international units, twice per day (IU, bid) for 14 days (96 patients), or a visually-identical placebo capsule (97 patients). The clinical parameters measured were plaque index, crevicular fluid level, probing depths, bleeding on probing and attachment level changes. Data was recorded at baseline, two-, eight-, 12- and 24-weeks visits. A total of 189 patients completed the study (96 placebo, 93 Spiramycin). Statistically significant differences in probing depth, favoring Spiramycin, were seen at two weeks (p < 0.0125), eight weeks (p < 0.0020), 12 weeks (p < 0.0032) and 24 weeks (p < 0.0075). Spiramycin also produced a significant improvement in attachment level at 12 weeks (p < 0.0146). All other clinical parameters showed no difference between drug and placebo. This study shows that Spiramycin, as an adjunct to thorough scaling and root planing, provides a statistically significant improvement in probing depths for up to 24 weeks when compared with scaling and root planing alone. Both longer studies and microbiologic evaluations are necessary to determine whether a more lasting benefit is possible.

Alpha-1-antitrypsin variation in Southern Africa.

Eleven Southern African populations were shown to be polymorphic at the alpha 1-antitrypsin locus. A 'new' electrophoretically detectable alpha 1-antitrypsin variant (PiWsan) which has a lower isoelectric point than does PiM, was found in the Bantu-speaking Negro and San populations. PiWsan appears to be functionally normal as judged by quantitative and qualitative studies.

Rapid assessment of health status and preventive-medicine needs of newly arrived Kampuchean refugees, Sa Kaeo, Thailand.

In the disaster relief programme for Kampuchean refugees in Thailand, epidemiological techniques were incorporated into the health-planning process during the first 2 weeks of the refugee influx. The findings influenced not only health care in the first refugee camp but also the delivery of medical services in subsequent camps. The mortality rate in the first week of refugee settlement was 9.1/10 000/day, and fell to 0.71/10 000/day by the fifth week. Children aged 4 and under had the highest risk of death. Fever/malaria was the main cause of morbidity and mortality. Simple epidemiological techniques, if initiated early in the relief effort, can influence medical decisions and lead to more effective use of health resources.

New dimensions in computed tomography.

Total body CT scanning may be utilized as a means of treatment planning for radiation therapy. Computer reconstruction of coronal and sagittal views from CT cross-sectional slices was accomplished by taking each of the cross-sectional images and placing them together in the specific order in the sequence in which they were scanned to form a cube. Once the cube is built, retrieving in the sagittal and coronal views is readily achieved.

Definitive treatment of carcinoma of the rectum by intracavitary radiation therapy.

A combination of external and contact irradiation treatment has been used successfully in treatment of selected patients with carcinoma of the rectum. The advantages include eliminating a permanent colostomy. If the treatment is unsuccessful in controlling the lesion, electrocoagulation and abdominoperineal resection are still available.
