There is a low autopsy rate and wide distribution of computed tomography (CT) and magnetic resonance imaging (MRI) scanners in Japan. Therefore, many Japanese hospitals, including 36% of the hospitals with in-patient facilities and 89% of large hospitals with ER facilities conduct postmortem imaging (PMI), use clinical scanners to screen for causes in(More)
BACKGROUND Anastrozole and tamoxifen have mild toxicity. However, we noticed that more patients treated with anastrozole complained of joint symptoms than expected. In particular, digital stiffness as is seen with rheumatoid arthritis is a problem. Some clinical trials of anastrozole in Europe and the United States reported musculoskeletal disorders as(More)
We report prolonged unilateral vasodilatation and hemispheric brain edema in a 49-year-old man with fulminant hepatic failure (FHF). The patient presented with a tonic-clonic seizure caused by a hypertensive subcortical hemorrhage in the left parietal lobe. Serial computed tomography (CT) scans showed progressive darkening of the ipsilateral hemisphere,(More)
PURPOSE Most traumatic deaths in Japan are due to nonpenetrating injuries, especially those that result from traffic accidents; however, the autopsy rate of traffic accident-related deaths is only about 5%. We investigated the diagnostic ability of postmortem computed tomography (PMCT) in cases of fatal trauma after traffic accidents. MATERIALS AND(More)
Case 1: A 34-year-old woman,who had a right breast cancer with axillary lymph node metastasis and multiple bone metastases, was referred to our clinic. She developed paralysis of lower extremities and disorder of the bladder and rectum due to metastasis to the thoracic vertebra, and also had renal dysfunction due to severe hypercalcemia and hemorrhagic(More)
The 68-year-old man took arsenic pasta 1 g (arsenic trioxide 0.45 g) to commit suicide and was admitted 16 hours after ingestion. He developed vomiting and coma, followed by pancytopenia. He was treated with activated charcoal, laxative, dimercaprol, sodium thiosulfate and direct hemoperfusion with good recovery. Total arsenic concentrations in serum and(More)
Polymicrogyria (PMG) is a complex malformation accompanied with abnormal cortical laminations (two-, four- or six-layered cortex), and horizontally oriented myelinated fiber layer is evident in four-layered PMG in older individuals. Here we report a 65-year-old man with refractory epilepsy, in whom postmortem examination revealed four-layered PMG in the(More)
There are many dangerous materials which cause poisoning, toxins or poisons, in our lives. We may suddenly suffer from the effects of these materials by inhalation or ingestion before we are aware of the risk. It is very important to identify toxins or poisons to prevent poisoning and treat the poisoned patients. We have to learn from previous accidents the(More)
PURPOSE Our purpose was to evaluate image delineation ability of contrast-enhanced post-mortem computed tomography (CEPMCT) using cardiopulmonary resuscitation technique of chest compression, named "resuscitation CEPMCT". MATERIALS AND METHODS Non-traumatically-deceased 15 subjects (7 men; 8 women) aged 19-87 years (mean 61 years) underwent resuscitation(More)
