If hypovolaemia is most probably responsible for the hypotension, fluid resuscitation should be initiated. The therapy of choice is infusion of sugarless, isotonic crystalloids with a physiologic serum electrolyte composition. In patients with brain injuries a decrease in serum osmolality is not advisable and hypertonic fluids may therefore be considered. Human albumin preparations are no longer indicated, but synthetic colloids may be an adjunct to a pure crystalloid regime. Hydroxyethyl starch preparations with a molecular weight in the mean range are reasonable choices considering the individual advantages and disadvantages of the various colloids. Larger blood losses must be treated with blood components such as packed red cells, fresh frozen plasma and thrombocyte concentrates as indicated. There are no widely accepted values for laboratory or monitoring parameters in starting or stopping a given fluid therapy; these values are unquestionably influenced, among other things, by the patient history and the pattern of the injuries. Initial resuscitation (when to start, who should administer the fluid and how much) also remains a focus of heated controversy.</p>","PeriodicalId":21484,"journal":{"name":"Schweizerische medizinische Wochenschrift","volume":"130 42","pages":"1509-15"},"PeriodicalIF":0.0,"publicationDate":"2000-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21917923","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}

Due to the lack of controlled clinical trials in this field, the growing evidence that hypotensive resuscitation results in improved long-term survival mainly stems from experimental studies in animals. The main differences between concepts for the reduction of blood loss in systemic hypotension are between \"deliberate hypotension\" (synonym \"controlled hypotension\", used intraoperatively), \"delayed resuscitation\" (where the hypotensive period is intentionally prolonged until operative intervention) and \"permissive hypotension\" (where restrictive fluid therapy increases systemic pressure without reaching normotension). In this review the concept of \"permissive hypotension\" is delineated on the basis of macro- and microcirculatory changes secondary to hypovolaemia and low driving pressure, and the potential indications and limitations are discussed.</p>","PeriodicalId":21484,"journal":{"name":"Schweizerische medizinische Wochenschrift","volume":"130 42","pages":"1516-24"},"PeriodicalIF":0.0,"publicationDate":"2000-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21917924","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}

It complicates about 10 per 1000 admissions in critical care, where it represents 10-15% of all nosocomial infections. Candidiasis remains difficult to diagnose and its mortality is as high as those of septic shock (40-60%). A better knowledge of the pathophysiology of the disease and the availability of triazole compounds that are less toxic than amphotericin have given rise to the concept of early empirical or preemptive treatment. Prophylaxis of invasive candidiasis, which is very effective, is based on risk factor identification.

From July 1996 to December 1997, all laboratories performing serological tests for Lyme borreliosis sent a questionnaire to the treating physicians whenever the tests were positive. In addition, the physicians who diagnosed a case on clinical grounds only were also asked to report these cases. During this period, 1460 positive serological tests were recorded among approximately 10,360 performed (14%). A total of 775 questionnaires were returned (53%). In 3/4 of the cases, the test was ordered because of an acute clinical manifestation or a tick bite. The rest related to chronic symptoms or follow-up. In 504 cases (65%), diagnosis was considered certain or probable. These were erythema migrans in 46%, clinical manifestations of stage II in 33% (26 facial palsy, 20 acute arthritis, 5 benign cutaneous lymphocytoma) and chronic symptoms in 21% (23 acrodermatitis, 26 neuropathies, and 8 arthritis). The adjusted incidence, estimated on the basis of the treating physician's place of residence, ranged from 9/100,000 in Valais to 95/100,000 in Neuchâtel.

It brought together physicians and scientists from five university hospitals (Basel, Berne, Geneva, Lausanne and Zurich) and two Cantonal hospitals (Lugano and St. Gallen). The objective of SHCS was, and still is, to produce rapid, high quality patient-oriented medical research in the field of HIV infection.</p><p><strong>Methods: </strong>SHCS is a prospective population-based cohort study. Any HIV-infected person aged > or = 16 years is eligible to participate. Data collection and study procedures are standardised. Data quality and protocol monitoring are conducted at the coordination and data centre in Lausanne. Detailed information on demographics, income, mode of HIV acquisition, risk behaviours, clinical events, laboratory results, treatment and treatment tolerance is collected at registration and at 6-monthly intervals.</p><p><strong>Results: </strong>Since 1996, 10,600 persons have been enrolled and the SHCS study population is considered fairly representative of the HIV-infected population in Switzerland, at least in terms of gender and mode of HIV acquisition. In 1999, 4600 patients were actively followed up and more than 70% of patients were receiving highly active antiretroviral therapy (HAART). As a consequence, mortality and the incidence of HIV-related opportunistic infections have decreased significantly in the recent past. Between 1996 and 2000, 91 original manuscripts have been published by SHCS scientists and physicians, almost exclusively in peer-reviewed journals. A wide range of scientific questions have been addressed, including HIV primary infection, the natural history of HIV infection, the clinical and biological impact of HAART, drug resistance, risk factors for disease evolution including the timing of treatment initiation, the role of CD4 receptors, the validity of HIV surveillance reports, determinants of treatment access and tolerance, clinical trials of new drug combinations, the interruption of prophylaxis following a favourable response to HAART and issues relating to quality of life and interaction between income, social level and disease evolution.</p><p><strong>Conclusion: </strong>The SHCS has had, and continues to have, a significant impact on medical practice, public health and research in Switzerland and beyond. It represents a network of excellence which has brought together and fostered intensive collaboration between physicians and institutions throughout this country and beyond.
