[A simple method to detect disaccharides deficiency].

A simple method, easy to perform during an endoscopic procedure, fast and inexpensive, that allows detecting deficiencies in lactase, sucrase or maltase activities is presented. Briefly, method consists in placing a duodenal biopsy sample in an adequate vial containing lactose, sucrose or maltose solution during a few minutes, and then, adding a few drops of a glucose reactive from commercial origin. Presence of any enzymatic activity is demonstrated when released glucose from any of the disaccharides chosen reacts with the second reactive, turning solution to a red colour. Its utility is discussed and compared with other diagnostic methods.

Psychiatric morbidity and physical illness in health centres.

This study examined, in health care attenders, the effect of different sociodemographic variables and physical illness on the probability of suffering from mental disorders. In health centres, the prevalence of mental disorders was 19.3% (12.4% for males and 23.8% for females). Logistic modelling was used to investigate the joint effect on psychiatric morbidity of 6 sociodemographic variables and physical illness. It was found that sex, age, and physical illness exerted independent but not interactive effects on the probability of psychiatric morbidity.

The factor structure of the GHQ-60 in a community sample.

The factor structure of the 60-item version of the General Health Questionnaire was explored, using data collected in a community study in a rural area of northern Spain. Six principal components, similar to those previously reported with this instrument, were found to provide a good description of the data structure. The 30-item and 12-item versions of the GHQ were then disembedded from the parent version, and further principal components analyses carried out. Again, the results were similar to previous studies: in each of the three versions analysed here, the two most important components represented a disturbance of mood ('general dysphoria')--including aspects of anxiety, depression and irritability--and a disturbance of social performance ('social function/optimism'). The principal component structure of the GHQ-60 was then utilized to calculate factor scores, and these were compared with PSE ratings using Relative Operating Characteristic (ROC) analysis. While four of the six factors discriminated well (area under the ROC curve 0.75 or more) between PSE 'cases' and 'non-cases', only one, depressive thoughts, was a good discriminator between depressed and non-depressed PSE 'cases'.
