Anandamide absorption by direct hemoperfusion with polymixin B-immobilized fiber improves the prognosis and organ failure assessment score in patients with sepsis.
Direct hemoperfusion (DHP) with polymixin B-immobilized fiber (PMX) has been reported to be effective for patients with septic shock. The aim of this study was to clarify the mechanism of PMX-DHP effect on septic shock. ⋯ ANA, an intrinsic cannabinoid that induces hypotension in septic shock, is inferred to be the main mechanism of the PMX-DHP effect. Removal of ANA by PMX-DHP could be key to successful septic shock treatment.

As the result of a locking phenomenon that may occur in a guidewire inside a metal puncture needle when using the Seldinger technique to insert a central venous catheter, the guidewire can break and cause an embolism. To counter this possibility we devised a guidewire with a structure that made it difficult for locking to occur and compared it to conventional guidewires. Conventional guidewires are wound lengthways with a spring. ⋯ We then compared the frequency of locking and the frequency of bending of the guidewire tips that have been withdrawn. In group A, locking occurred in 72% of the cases where the guidewire was unable to be inserted, but this figure was 0% in group B. The improved guidewire has the advantage of reducing the risk of locking and of guidewire breakage.

Case ReportsChanges on MRI in lumbar disc protrusions in two patients after intradiscal electrothermal therapy.
We examined changes to the protruded lumbar disc after intradiscal electrothermal therapy (IDET) using magnetic resonance imaging (MRI) in two patients with chronic discogenic low back pain who underwent IDET. MRI was performed before and 6 months after the treatments. In the follow-up MRI studies, the protrusions were almost abolished and normalized in both patients. We thus confirmed shrinkage of the protruded disc by IDET on MRI images in two patients.

Randomized Controlled Trial Clinical TrialEffects of landiolol on hemodynamic response and seizure duration during electroconvulsive therapy.
This study was done to evaluate the effect of landiolol, an ultra-short-acting beta-blocker, on the hemodynamic response and the duration of seizure activity during electroconvulsive therapy (ECT). ⋯ As the landiolol dose of 0.2 mg x kg(-1) caused shorter seizure duration, and because the hemodynamic effects after ECT of the 0.1 mg x kg(-1) and 0.2 mg x kg(-1) doses were similar, it was concluded that a 0.1 mg x kg(-1) landiolol bolus was the appropriate dose pretreatment before ECT.
