Lung cancer, with its high incidence and poor prognosis, is a particularly interesting disease for these studies. The retinoids are a promising group of chemopreventive agents, since they are involved in growth control and are a necessary cofactor for proper activity of a protein receptor which we have shown to be a lung cancer suppressor. Nevertheless, the toxic side effects of retinoids at pharmacological dose present difficulties and current studies are aimed at determining the efficacy of various forms of retinoids and chemoprevention protocols in the target populations.</p>","PeriodicalId":18049,"journal":{"name":"L'union medicale du Canada","volume":"122 6","pages":"442-5"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19291940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Profile of Chlamydia test utilization by the physicians of Laval].","authors":"L Arcand,&nbsp;H Arruda","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Before recommending systematic screening for Chlamydia trachomatis in young sexually-active women in its population, the Laval Community Health Department set out to document current practices in chlamydia testing. The objective of the study was to determine for whom these tests were prescribed, by whom and why. Data were obtained from a representative sample of 413 medical records. The greatest proportion of tests were prescribed for young women between the ages of 15-24 years. More than 85% of the tests were ordered by general practitioners, most of whom practiced in both hospital setting and private clinics. More than half of the tests were administered to obtain a diagnosis; approximately 42% were done for screening purposes. The study revealed a failure to document the sexual history of patients. It was estimated that between 30 and 40% of Chlamydia tests were not justified in being prescribed (according to the recommendations in the literature). It is possible that the criteria in the medical literature are too complex for use in everyday practice. The authors recommend the creation of specific tools adapted to physicians' needs, and the development of a screening program based on a systematic, step-by-step approach to determine whether or not a test is warranted.</p>","PeriodicalId":18049,"journal":{"name":"L'union medicale du Canada","volume":"122 6","pages":"446-52"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19291890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, in the absence of pre mortem biological markers, cognitive deficits form the starting point and the basis of inclusion criteria on which the clinician relies in order to make a putative diagnose of dementia of the Alzheimer type (DTA). Cognitive deficits should thus be accurately described through neuropsychological testing since it is essential to identify the cognitive deterioration patterns of the patients--in terms of selective impairment of cognitive functions--as well as the evolution of these patterns. Regarding this issue, the classical teaching of the Geneva school has proposed a homogeneous deterioration of the aphasic-apraxicagnosic syndrome into four stages. However, recent work does not support this hypothesis. On the contrary, these studies tend to show the presence of heterogeneity in neuropsychological manifestations of the disease. The aim of the present paper is to provide a critical review of this topic through a brief survey of the classical work and research that have recently been conducted. An analysis of the possible candidates responsible for the existence of this heterogeneity of cognitive profiles is presented. Finally, theoretical implications and clinical repercussions are discussed.</p>","PeriodicalId":18049,"journal":{"name":"L'union medicale du Canada","volume":"122 6","pages":"420-6"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19291937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
