Routine hysteroscopy for patients with a high risk of uterine malignancy

Seventy patients with abnormal vaginal bleeding were examined with a Storz hysteroscope. The examination took an average of only 5 min. Sixty patients had the examination under general anaesthesia, five under paracervical block and five had no form of anaesthesia. All tolerated the procedure well. There were no complications directly related to the hysteroscopic examination. There was complete correlation between the histology of the endometrium obtained at subsequent curettage and the hysteroscopic findings.     

Plasma lyso-phosphatidylcholine concentration is decreased in cancer patients with weight loss and activated inflammatory status

Background  

It has been observed that ras-transformed cell lines in culture have a higher phosphatidylcholine (PC) biosynthesis rate as well as higher PC-degradation rate (increased PC-turnover) than normal cells. In correspondence to these findings, the concentrations of the PC-degradation product lyso-phosphatidylcholine (LPC) in cancer patients were found to be decreased. Our objective was the systematic investigation of the relationship between LPC and inflammatory and nutritional parameters in cancer patients. Therefore, plasma LPC concentrations were assessed in 59 cancer patients and related to nutritional and inflammatory parameters. To determine LPC in blood plasma we developed and validated a HPTLC method.     

Moderate drinking in ex-alcoholics: recent studies

The literature on the occurrence of moderate drinking in ex-alcoholics that has been published since the Rand report in 1976 is reviewed. Although differences in diagnosis, definitions of moderate drinking and length of follow-up make strict comparisons of the studies difficult, the majority of studies seem to indicate that the earlier reports of the frequency of such moderate drinking may be overly optimistic. Depending on the definition of moderate drinking that is used, the longer the interval required for alcoholics to sustain moderate, problem-free drinking, the less likely is such an outcome. Among treated alcoholics, the percentage probably ranges from about 2 to 12%; the percentage may be higher among alcoholics identified in community population samples. Thus far, the only factor common to alcoholics who are able to achieve moderate drinking is their being mild cases (i.e., having fewer lifetime alcohol-related problems than other alcoholics). Factors pertinent in assessing discrepancies between the various studies are discussed.
