Multidetector computed tomography to detect ingested press-through packages: utility of multiplanar reconstruction imaging in the emergency department.

Case: We investigated the usefulness of multidetector computed tomography during examination in the emergency department to detect the location of press-through packages that had been inadvertently swallowed. In three patients, four press-through packages were detected on multi-planar reconstruction of multidetector computed tomography images, with three lodged in the esophagus and one in the stomach.

Outcome: The multidetector computed tomography detection rate of press-through packages was 100% in patients who realized they had swallowed the packages by mistake.

Case of multiple organ failure due to benzine ingestion.

A 42-year-old woman was admitted to our ICU for acute respiratory failure due to benzine ingestion. On arrival at the hospital, the patient's consciousness level was GCS 3 and her SpO2 was 89% when receiving oxygen at 10 L/min. She was immediately intubated and placed on a ventilator.

Complicated interaction between psychostimulants and morphine in expression of phenotype of behavior in the dopaminergic system of BALB/c mice.

It is believed that BALB/c mice appear to be less sensitive to the locomotor effects of abused drugs compared to other strains, and several behaviors induced by abused drugs depend on genetic factors. The present study was designed to investigate the effects of the interaction between psychostimulants and morphine on behavior in BALB/c mice. Morphine and cocaine induced hyperlocomotion and hypolocomotion, respectively, while methamphetamine did not affect locomotor activity and high doses of methamphetamine significantly increased self-injurious behavior.

Involvement of free radicals followed by the activation of phospholipase A2 in the mechanism that underlies the combined effects of methamphetamine and morphine on subacute toxicity or lethality in mice: comparison of the therapeutic potential of fullerene, mepacrine, and cooling.

An increase in polydrug abuse is a major problem worldwide. The coadministration of methamphetamine and morphine increased subacute toxicity or lethality in rodents. However, the underlying mechanisms by which lethality is increased by the coadministration of methamphetamine and morphine are not yet fully understood.

Underlying mechanism of combined effect of methamphetamine and morphine on lethality in mice and therapeutic potential of cooling.

An increase in polydrug abuse is a major problem worldwide. A previous study showed that coadministration of methamphetamine and morphine induced lethality in rodents and humans. However, the underlying mechanisms by which the lethality is increased by the coadministration of methamphetamine and morphine have not been fully understood.

Recent trend of the incidence of sudden infant death syndrome in Japan.

Objectives: To clarify the trend of the incidence of SIDS in the last 20 years in Japan to provide the basis for health administration training.

Method: We have studied the SIDS incidence rate, the infant mortality rate, the neonatal mortality rate and perinatal deaths of the last 20 years in Japan and calculated the rate at which SIDS has contributed to infant mortality.

Result: We found that the 2001 SIDS incidence rate in Japan was 0.
