Scurvy, a severe form of vitamin C deficiency, killed scores of people until its cause and treatment were firmly established at the end of the eighteenth century. Since then, cases have surged periodically around the world, mostly in developing countries and during times of war and famine. In developed countries, scurvy is still endemic and evidence is growing that vitamin C deficiency might affect up to 30 percent of the population. Low socio-economic status, alcoholism, severe psychiatric illness leading to poor nutrition and critical illness are significant risk factors. We hereby report the case of a patient admitted in a Swiss intensive care unit of a tertiary teaching hospital and presenting with clinical signs and symptoms of severe vitamin C deficiency.
Using data from the Public Health Service, we studied the demographic and clinical characteristics of 1,782 patients enrolled in methadone maintenance treatment (MMT) during 2001 in the Swiss Canton of Vaud, comparing our findings with the results of a previous study from 1976 to 1986. In 2001, most patients (76.9%) were treated in general practice. Mortality is low in this MMT population (1%/year). While patient age and sex profiles were similar to those found in the earlier study, we did observe a substantial increase in the number of patients and the number of practitioners treating MMT patients, probably reflecting the low-threshold governmental policies and the creation of specialized centers. In conclusion, easier access to MMT enhances the number of patients, but new concerns about the quality of management emerge: benzodiazepine as a concomitant prescription; low rates of screening for hepatitis B, C and HIV, and social and psychiatric preoccupations.
Central venous catheter (CVC) placement, even if performed under duplex scan control, may be associated with incidental arterial injury leading to increased morbidity, mortality, and prolonged hospital stay. Erroneous CVC placement in the carotid or subclavian arteries has been usually treated surgically because those puncture sites may not be efficaciously compressed manually. However, surgery in this setting may be challenging because of difficulty of access for the catheters positioned in the subclavian artery and of the risk of cerebrovascular complications for carotid catheters. Recently, several cases have been published, describing the successful endovascular management of iatrogenic arterial injury using different types of vascular closure devices (VCD). However, in this setting, it remains difficult to be completely sure that the VCD has achieved complete hemostasis and that the patient does not subsequently incur in a clinically silent intrathoracic bleeding. We report the case of an erroneous CVC placement in the right subclavian artery successfully retrieved using an Angioseal VCD. The immediate and complete hemostasis at the puncture site was confirmed at angiography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
