Filter by:Legalon® SIL will be administered to patients with amatoxin poisoning diagnosed by history, gastrointestinal symptoms, elevated liver enzymes, and/or diagnostic assay (should one become available). Patients may or may not also demonstrate abnormalities in bilirubin and/or creatinine. Treatment consists of a 5 mg/kg loading dose followed by 20 mg/kg/day via continuous infusion. The treating physician is expected to administer supportive therapy of his/her choosing but consistent with best practices. Legalon® SIL will be stopped when coagulopathy is no longer present, and when liver function tests have returned significantly towards the normal range. Patients will be followed 7-14 days after the end of Legalon® SIL therapy with follow up lab studies.
Carbon monoxide (CO) has been called a "silent killer", and those patients who survive CO poisoning are at risk of neurological damage, which may be permanent. CO is a leading cause of unintentional poisoning deaths in the United States, and the odorless gas results in an estimated average of 20,636 emergency department (ED) visits each year. Oxygen is the antidote for CO poisoning, and it acts both by attenuating toxic effects and enhancing elimination. A fractional inspired concentration of oxygen (FiO2) of 0.7 to 0.9 may be achieved by administration of 100% oxygen delivered using a reservoir with a facemask that prevents rebreathing. Hyperbaric oxygen therapy may provide added benefit for patients with CO poisoning, but this therapy is unavailable in many parts of the United States including Vermont. Use of a continuous positive airway pressure (CPAP) mask may achieve an FiO2 of 1.0, but the effects of delivering an FiO2 of 1.0 compared to 0.7 in CO poisoning are unknown. CPAP, by comparison, is inexpensive, portable, and available in most EDs. In this study, the investigators are testing the hypothesis that oxygen delivered by CPAP will improve both CO washout kinetics and functional outcomes, compared to the standard therapy of oxygen delivered by non-rebreathing facemask. Specific Aim 1 will provide toxicokinetic data to support a potential benefit in the use of CPAP for CO poisoning, by comparing CO elimination kinetics in response to oxygen therapy delivered by non-rebreathing facemask versus CPAP. The 20 patients expected in our first year will provide adequate power to detect a 20% fall in half-time of CO elimination. While CPAP may increase CO washout rates, as predicted in Specific Aim 1, demonstration of real functional benefit will be tested in Specific Aim 2. This Aim seeks to determine functional (neuropsychological) outcomes in patients with CO poisoning treated with oxygen therapy delivered by non-rebreathing facemask versus CPAP. Data showing a therapeutic benefit from CPAP in CO poisoning would have clinical implications. Compared to hyperbaric oxygen therapy, CPAP therapy can begin earlier, including the pre-hospital setting, for patients with known exposure. With the frequent nature of CO poisoning and the widespread availability of CPAP, a potential benefit could lead to improved outcomes for the 20,000+ patients who present to EDs annually.
Patients with failed extubation stay significantly longer in an intensive care unit (ICU) and have a higher mortality rate, than those intubated successfully. Reintubation is associated with life-threatening complications and a poor prognosis. Functional respiratory tests are frequently used as weaning parameters, however, they are not accurate enough to predict extubation failure. The incidence of swallowing dysfunction is underestimated, mainly among patients whose intubation lasts longer than 48 h.We previously observed that the assessment of the swallowing function and oropharyngeal motricity, conducted by the physiotherapist before extubation could be helpful for making decisions to extubate patients intubated for over 6 days. The objective of this study is to validate a scale previously devised and used for physiotherapist bedside evaluation of the swallowing function and oropharyngeal motricity, among patients intubated for over 6 days, to determine whether this scale is a good predictor of airway secretion-related extubation failure.Expected results : to validate a scale previously devised called " physiotherapist evaluation of the swallowing function and oropharyngeal motricity before extubation" by the mean of a multicentric study. In our hypothesis the clinical parameters studied could be predictive of extubation failure. Then, this evaluation could help the medical decision in the choice of the good time for extubation. The final objective is to lower the mortality related to extubation failure.
The data available for the efficacy of AScVS and prazosin is generated through different trials done in different clinical setting. Hence it was felt worthwhile to confirm the documented efficacy of AScVS and prazosin in terms of time taken for clinical recovery in a clinical trial. Along with this, effects of both the therapies on various biochemical parameters will be recorded and compared with. It was also felt necessary to study the effect of combination on the clinical outcome.
This retrospective study was conducted to collect data from approximately 100 patients from 6 months to 18 years of age who were stung by a scorpion but were not treated with antivenom. The study consisted of a review of hospital records of patients who were admitted for intensive care management of scorpion envenomation, at the only two hospitals in North America known to admit children routinely for scorpion sting management without antivenom. The standard of care consisted of symptomatic and supportive care, including airway maintenance, fluid and electrolyte support and, if necessary, sedation.
There is no FDA approved therapy for the treatment of scorpion envenomation, Centruroides scorpion envenomation produces a pattern of neurotoxicity with a spectrum of severity ranging from trivial to life threatening. Patients stung by Centruroides scorpions develop a clinical syndrome which may require sedation with benzodiazepines and observation for 6 to 28 hours of intensive care monitoring. A safe therapy is necessary to halt the progression of symptoms early in the clinical course while avoiding the clinical deterioration that can occur en route to a tertiary facility. Alacramyn® is anticipated to be safer and more effective than the present standard of care, midazolam, and faster-acting such that the need for transport of most rural patients will be eliminated and will reduce hospitalization time. The working hypotheses are as follows: 1. The investigational antivenom is safe as treatment of scorpion sting envenomation. 2. The investigational antivenom is effective as treatment of scorpion sting envenomation.
This treatment protocol will enable therapeutic use of Anascorp in the management of systemic manifestations of scorpion sting envenomation, in patients for whom antivenom would otherwise be unavailable. The working hypotheses are as follows: 1. The investigational antivenom is safe as treatment of scorpion sting envenomation. 2. The investigational antivenom is effective as treatment of scorpion sting envenomation.

This study will examine the risks of workplace exposure to benzene, a substance known to lead to cancer of the blood and possibly of the lungs. It is used widely in industries and is a contaminant in the environment. Researchers from the National Cancer Institute and the China Center for Disease Control (formerly Chinese Academy of Preventive Medicine) had done previous studies of workers in manufacturing industries in China of people who worked at least 1 day from 1972 to 1987 in 12 cities in that country. Data were collected of approximately 75,000 workers exposed to benzene and 35,000 who were not, with the purpose of investigating the relationship between benzene exposure and cancer risk. For workers exposed to benzene, there was a significant risk of cancer affecting the blood cells and a 1.8-fold excess of lung cancer among them. This study will expand those findings and also identify the effects of benzene amounts and whether there is a genetic tendency for benzene poisoning. About 3,860 benzene-exposed workers from the 12 cities will be interviewed. Next-of-kin of deceased workers, and a subcohort (additional grouping) of participants will serve as a control group in the research. Patients who have worked at places where there was exposure to benzene will have a brief physical exam and samples of cells from a mouth rinse and samples from blood will be collected to study the genetic influence on developing blood diseases from workplace exposures. All participants or next-of-kin, for deceased, will be given a questionnaire about their work history, use of cigarettes and hair dyes, medications they take, and family history of cancer. Interviews of about 40 minutes long will be conducted at participants homes or workplaces, at a time convenient to them, and the interviews will be audiotaped.
Childhood Lead Poisoning is a widespread disease that has few effective treatments. The specific aims of this proposed clinical trial are threefold: - To determine whether a six-week course of a newly formulated d-penicillamine suspension will effectively reduce blood lead level in children aged 6 months to 16 years with blood lead levels of 15-25 μg/dL. - To determine whether d-penicillamine chelation produces a sustained reduction in blood lead level in comparison with succimer and other lead chelators which always produce a significant post-treatment "rebound". - To determine whether chelation with d-penicillamine improves the physiologic disturbances that can be measured in children with blood lead levels in this range.
