Effect of a Device-Free Compressed Shell Fixation Method on Hepatic Respiratory Movement: Analysis for Respiratory Amplitude of the Liver and Internal Motions of a Fiducial Marker

Purpose

Suppression of respiratory movement of the liver would be desirable for high-precision radiation therapy for liver tumors. We aimed to investigate the effect of our original device-free compressed shell fixation method and breathing instruction on suppression of respiratory movement. The characteristics of liver motion based on the movement of a fiducial marker were also analyzed.

Association of the time to first epinephrine administration and outcomes in out-of-hospital cardiac arrest: SOS-KANTO 2012 study

Objective

This study assessed the association between the timing of first epinephrine administration (EA) and the neurological outcomes following out-of-hospital cardiac arrests (OHCAs) with both initial shockable and non-shockable rhythms.

SALVAGE THERAPY IN PATIENTS WITH UNRESECTABLE HILAR CHOLANGIOCARCINOMA

We describe our methods and outcomes of multidisciplinary treatments in patients with unresectable hilar cholangiocarcinoma. Fifty‐seven patients with a known outcome were enrolled. Thirty‐four of 57 patients were treated and evaluated by salvage therapy. For salvage therapy, we used internal and external radiotherapy, photodynamic therapy, YAG laser therapy and microwave coagulation therapy. The median survival time was 548 days for the group receiving salvage therapy and 198 days for the group not receiving this treatment. In conclusion, although no randomization of the patients was performed in this retrospective study, our present data provide convincing evidence that salvage therapy is a useful therapeutic approach for unresectable hilar cholangiocarcinomas.     

Investigation of recent problems in an acute care psychiatric ward considering the number psychiatrists working in the ward]

In July 2001, psychiatric wards for acute treatments (PWAT) were investigated in Japan using a questionnaire to clarify current and recent problems in 79 PWAT. The questionnaires were sent to wards, patients and psychiatrists and were returned by 72.2% overall. The number of admissions per ward was calculated as 21 patients per one month, and comprised half of all admissions to the hospital. 50% were schizophrenia, 17% were affective disordes and 16% involved drug abuse. Seventeen patients were discharged from PWAT per one month, and comprised 43% of all patients discharged from the hospital. These results indicate that both 21 patients admitted and 17 patients discharged per month and needs to maintain the essential standard for PWAT and the standard should be come more flexible as admission from the other unit of ward than PWAT. As rate of re-admission within 3 months after discharge was around 10% of the total number of patients in the ward, 3 months was considered suitable length of acute treatment in the field of psychiatry in Japan. There was one psychiatrist working in PWAT, and specialized psychiatrists had 17.4 patients, the most number of patients among types of psychiatrist. Simulations of one psychiatrist to 16 and to 32 patients in PWAT were performed to determine how many psychiatrists were needed for a ward. When the ratio was 32 patients to 1 psychiatrist, it was necessary to increase the number of psychiatrists to a ward by 1, and in the case of 16 patients, 1-3 psychiatrists were needed. These indicate the standard number of psychiatrists for PWAT should be at most one psychiatrist for the ward or all of the psychiatrists working in PWAT should be allowed to work simultaneously in other wards. Preparing wards to treat acute phase psychiatric patients is a very important role of each psychiatric hospital, the standard for PWAT should include not only a high level of medical staff, but also preparing easy criteria for each hospital.
