RESUMO
BACKGROUND: The cutaneous application of vegetable oil as a therapeutic practice and dietary coadjuvant has been described mainly in adult patients at risk for essential fatty acid deficiency. In the current study, the effects of cutaneous soybean oil application on somatic growth and plasma linoleic and arachidonic acid levels were examined in enterally fed preterm newborns. METHODS: Sixty consecutive preterm infants were chosen from patients admitted to the nursery. Infants were randomly assigned to one of two groups: the oil group, which was treated cutaneously with soybean oil, or the control group, which received no cutaneous treatment. RESULTS: After 30 days, a significant increase in anthropometric parameters was observed in infants who received cutaneous oil, mainly in infants small for gestational age. An increase in linoleic acid level and a decrease in arachidonic acid level were seen in both groups but do not justify the difference found in growth rates in the control and oil groups. CONCLUSIONS: Preterm infants treated cutaneously with soy oil showed better somatic growth than the control group. The factors leading to the present results, especially the response of the infants who were small for gestational age merit further evaluation.

The aim of this study was to determine frequency in which a double contrast colon radiography permits a correct diagnosis in colon carcinoma. The study was done at the Hospital Edgardo Rebagliati Martins IPSS in Lima. Previously the prevalence of colon carcinoma was identified at the place of the study between 1980 and 1991, this was 5%. We chose a representative number of patients, 50, with a confirmed pathological diagnosis of colon carcinoma, in which a double contrast colon radiography (C) was done before the diagnosis was made. The control group was 50 patients with colonic pathology other than carcinoma, in which a DC was performed previously to the diagnosis. Sensibility and specificity were 84 +/- 10% and 94 +/- 6% respectively for DC. The positive predictive value was 93 +/- 7%, the negative predictive value was 85 +/- 10% and efficacy 89 +/- 9%. We conclude that the double contrast colon radiography is of great usefulness for the diagnosis of colon carcinoma.

Traditional and current concepts, anatomical and physiological mechanisms, causes, classification, clinical manifestations, diagnostic approach, and current therapy of hemorrhoidal disease are reviewed in this article. It is encouraged to use the term hemorrhoidal disease instead of the misused one hemorrhoids.
