Facilitating Community Risk Communication for Wide-Area Evacuation during Large-Scale Floods.

Large-scale floods have been occurring more frequently in Japan as a result of current global weather anomalies, yet evacuation procedures face several issues. These include low evacuation rates of citizens, wide-area evacuation by car, and residents who cannot evacuate on their own. For example, in the Kofu Basin, Yamanashi Prefecture, due to the size of the potential inundation area and a population that exceeds 300,000 people spread across 10 municipalities, a large number of residents would have to evacuate across municipal boundaries by car.

[Prolonged disturbance of consciousness and respiratory depression induced by controlled-release morphine, requiring long-term naloxone administration in a hemodialysis patient with cancer--a case report].

An 82-year-old female on hemodialysis was diagnosed with advanced breast cancer. She received 20 mg of controlled-release oral morphine per day for the relief of cancer pain. After a total dose of 30 mg was administered, she was hospitalized with disturbance of consciousness.

Acute stress increases the synthesis of 7α-hydroxypregnenolone, a new key neurosteroid stimulating locomotor activity, through corticosterone action in newts.

7α-Hydroxypregnenolone (7α-OH PREG) is a newly identified bioactive neurosteroid stimulating locomotor activity in the brain of newt, a wild animal, which serves as an excellent model to investigate the biosynthesis and biological action of neurosteroids. Here, we show that acute stress increases 7α-OH PREG synthesis in the dorsomedial hypothalamus (DMH) through corticosterone (CORT) action in newts. A 30-min restraint stress increased 7α-OH PREG synthesis in the brain tissue concomitant with the increase in plasma CORT concentrations.

Biosynthesis, mode of action, and functional significance of neurosteroids in the purkinje cell.

The brain has traditionally been considered to be a target site of peripheral steroid hormones. In addition to this classical concept, we now know that the brain has the capacity to synthesize steroids de novo from cholesterol, the so-called "neurosteroids." In the middle 1990s, the Purkinje cell, an important cerebellar neuron, was identified as a major site for neurosteroid formation in the brain of mammals and other vertebrates.

Evaluation of low-dose propofol preadministration to attenuate vascular pain during induction of anesthesia.

Study Objective: To determine whether a small dose of propofol before induction decreases pain with injection using two different formulas of propofol-10% long-chain triglycerides (LCT) and medium-chain triglycerides (MCT) and LCT.

Design: Prospective, randomized, comparative study.

Setting: University-affiliated hospital.

[Newly developed BONFILS Retromolar Intubation Fiberscope for difficult airway].

Battery powered BONFILS Retromolar Intubation Fiberscope (BRIF) is a nonflexible fiberscope having the same curvature as the Macintosh laryngoscope for difficult airway. We used this device in two patients; A 65-year-old man with small chin and a 35-year-old man with neck spinal cord injury. Two trials of orotracheal intubation were accomplished easily in 20 seconds.

[Blood lactate levels during fast-track cardiac anesthesia].

Background: Lactate is a very sensitive marker of outcomes in critically ill patients. The aim of this study was to investigate the significance of blood lactate measurement during fast-track cardiac anesthesia.

Methods: We examined arterial blood lactate levels of 12 patients following coronary artery bypass graft surgery under intermittent aortic cross clamping with fast-track cardiac anesthesia.
