Determining entropy values equivalent to the bispectral index values during sevoflurane anaesthesia.
We aimed to identify the entropy levels that would be equivalent to the bispectral index (BIS) levels in sevoflurane anaesthesia in patients who are to undergo elective lumbar disc surgery. ⋯ Based on this observation, we think that general anaesthetic agents that might cause severe hypotension could be more safely administered under entropy monitoring.

Migraine is considered to be a multifactorial, complex disease. Various genetic and environmental factors contribute to the manifestation of this disease. The aim of this study was to determine whether polymorphisms in the tumour necrosis factor (TNF) region are associated with the risk of migraine. We examined the association between 6 single nucleotide polymorphisms in the coding regions of TNF-α and TNF-β genes and migraine. ⋯ Our data indicate that TNF-α and TNF-β gene polymorphisms are not a significant risk factor for migraine without aura in Greek children.

Information regarding gender differences in drug use of adolescents is essential for designing gender-specific drug prevention policies. This study was conducted in high school students in Tehran, Iran, in 2007. Here, we report the gender differences in lifetime prevalence as well as psychosocial associates of drug use. ⋯ Understanding this gender difference in predictors of lifetime use of illicit drugs in high school adolescents facilitates the design of gender-sensitive drug use preventive programmes. It seems that family variables may have more value in prevention of illicit drug use in male adolescents.

The NINDS trial demonstrated for the first time the effectiveness of intravenous thrombolysis in improving outcome after acute ischemic stroke. The absolute benefit of this intervention was 11-13% greater chance of being normal or near normal (MRS ≤ 1) at 3 months. ⋯ Intra-arterial thrombolysis achieves recanalization rates of 60-70%. Since tissue viability is clearly important, it is time to stop defining rigid time windows and if there is a large penumbra (20-50%) and the occlusion is in a large artery, there exists a logic and a growing evidence to consider either bridge therapy or direct intra-arterial therapy.

The determination of toxic elements in the biological samples of human beings is an important clinical procedure. This study was performed to investigate the prevalence of abnormal blood contents of 2 trace elements (TEs), aluminum (Al),and lead (Pb) in hemodialysis (HD) patients and to analyze their relationship with the medications, such as CaCO(3), Ca acetate, 1,25-dihydroxy vit. D(3), and erythropoietin (EPO), as well as hematocrit level. ⋯ The blood level of trace metals of these HD patients was not related to their medications except for the EPO dose. However, caution must be exercised in interpreting this result as dose and duration of medication may play an important role. Al and Pb over load may be considered from the causes of inadequate response to epoetin therapy.
