Abstract	Intramural esophageal dissection (IED), characterized by bleeding into the submucosal space, leads to mucosal separation and dissection. The most prevalent symptoms are sudden chest or retrosternal pain, hematemesis, and dysphagia. Therefore, acute coronary syndrome and aortic dissection are among its most notable differential diagnoses. A 31-year-old pregnant woman presented with acute chest pain, laryngeal discomfort, and hematemesis. Emergency esophagogastroscopy revealed longitudinal mucosal dissection (upper esophagus to esophagogastric junction). The patient was successfully treated by avoiding the ingestion of solid foods. Clinicians should consider a diagnosis of IED for pregnant patients with acute chest pain, especially if hematemesis is present.

Characteristics and Costs of Ladder Fall Injuries: A Report from a Single Emergency Center in Okayama

Abstract	We sought to identify the incidence, injury patterns, and financial burden of ladder fall injuries to provide a reference for reinforcing guidelines on the prevention of such injuries. We enrolled the patients who were injured in a ladder-related fall and required intensive care between April 2012 and March 2014 at Okayama University Hospital, a tertiary care hospital in Okayama City:9 patients injured in 7 stepladder falls and 2 straight ladder falls. The median patient age was 69 years, and 8 were males. Six falls occurred in non-occupational settings. Head injuries predominated, and the injury severity score ranged from 2 to 35 (mean＝21±12). At the time of discharge from the intensive care unit, one patient had died and 5 patients had some neurological disabilities. The case fatality rate was 11%. The total cost of care during the review period was ￥16,705,794, with a mean cost of ￥1,856,199 per patient. Ladder fall injuries are associated with a high rate of neurological sequelae and pose a financial burden on the health insurance system. A prevention education campaign targeting at older-aged males in non-occupational settings may be a worthwhile health service investment in this community.

Abstract	In adult high-frequency oscillatory ventilation (HFOV), stroke volume (SV) and mean lung pressure (PLung) are important for lung protection. We measured the airway pressure at the Y-piece and the lung pressure during HFOV using a lung model and HFOV ventilators for adults (R100 and 3100B). The lung model was made of a 20-liter, airtight rigid plastic container (adiabatic compliance: 19.3ml/cmH₂O) with or without a resistor (20cmH₂O/l/sec). The ventilator settings were as follows: mean airway pressure (MAP), 30cmH2O;frequency, 5-15Hz (every 1Hz);airway pressure amplitude (AMP), maximum;and % of inspiratory time (IT), 50% for R100, 33% or 50% for 3100B. The measurements were also performed with an AMP of 2/3 or 1/3 maximum at 5, 10 and 15Hz. The PLung and the measured MAP were not consistently identical to the setting MAP in either ventilator, and decreasing IT decreased the PLung in 3100B. In conclusion, we must pay attention to the possible discrepancy between the PLung and the setting MAP during adult HFOV.
