Prognostic value of blood lactate in critically ill patients
1984
Hyperlactatemia is frequently observed in critically ill patients. A correlation of blood lactate concentrations and outcome of patients has been proven in circulatory shock, circulatory arrest, acute myocardial infarction, acute hypnotic drug poisoning and severe pancreatitis. However, the prognostic relevance of hyperlactatemia yields from statistical examinations in larger groups of patients. It should not be misused as a reliable prognostic sign in the individual patient, but is of high value in comparing groups of patients. In individual patients, hyperlactatemia is a useful indicator pointing to the severity of illness and to superimposed complications. Blood lactate is of considerabl…
Theoretical Basis Versus Clinical Practice of Oxygen Parameters of Blood
1996
Under optimal conditions all oxygen parameters of human blood are defined at a theoretical basis, accepted and understood by the clinicians, measured correctly by instruments of different manufacturers and, therefore, leading to clear diagnoses for the patients.
Acute gastroenteritis outbreaks in Catalonia, Spain: norovirus versus Salmonella.
2008
Objective. To describe the epidemiology of norovirus (NV) and Salmonella gastroenteritis outbreaks in Catalonia between 15 October 2004 and 30 October 2005. Material and methods. Epidemiological data were obtained from outbreak reports. The aetiologic agent was investigated by culture for enteric bacteria, enzyme immunoanalyses, reverse transcription polymerase chain reaction (RT-PCR) and molecular epidemiology genotyping for NV. The x 2 test was used to compare proportions. Incidence rates and their confidence intervals (CI) were calculated assuming a Poisson distribution. Results. A total of 225 acute gastroenteritis (AG) outbreaks were reported, with 3436 persons affected and 115 hospita…
Der Effekt von Neostigmin an der motorischen Endplatte beim Intermediärsyndrom der Alkylphosphatvergiftung
1991
A patient with severe organophosphate intoxication received Neostigmine 1 mg IV during the intermediate syndrome. This dose resulted clinically and neurophysiologically in a marked deterioration of neuro-muscular transmission. This effect of neostigmine on the neuromuscular block during the intermediate syndrome (deterioration) differs from its effect on a similar pattern (improvement), which is seen in the delayed neuropathy following organophosphate exposure. The administration of therapeutic doses of cholinesterase inhibitors in patients with a reduced safety margin due to inhibition of endplate acetylcholinesterase may be dangerous.
Haemoperfusion: a useful therapy for a severely poisoned patient?
1986
Although it is many years since a haemodialysis and haemoperfusion over uncoated and later coated charcoal columns have been used for the treatment of intoxicated patients, the clinical efficacy of these extracorporeal techniques in the treatment of severely poisoned patients remains a matter of debate. Some of the reasons for this controversy may be the indiscriminate use of haemoperfusion in any form of intoxication, the lack of well-controlled studies and the wrong interpretation of the high haemoperfusion clearance values sometimes obtained. Simple pharmacokinetic principles are applied to this type of treatment and some practical guidelines as to how and when haemoperfusion should be …
Toxicological Findings of Self-Poisoning Suicidal Deaths: A Systematic Review by Countries
2022
The use of illicit and non-illicit substances is widespread in suicides. The toxicological data may help in understanding the mechanism of death. This systematic review aimed to analyze autopsies related to suicides by consuming poison, focusing on the correlation between substance use and the country of origin to create an alarm bell to indicate that suicide maybe attempted and prevent it. The systematic review was conducted according to the PRISMA guidelines, with the primary objective of identifying autopsies conducted in cases of suicide by consuming poison in specific geographic areas. Significant differences in substances were observed between low-income and Western countries that con…
