Hemodialysis patients are at an increased risk of bleeding due to the platelet dysfunction caused by uremia and the use of anticoagulants during dialysis. Spontaneous spinal hematoma is a rare disorder as a complication in hemodialysis patients. ⋯ Here, we report the case of 77-year-old woman who presented with spinal cord compression due to spontaneous spinal epidural hematoma associated with hemodialysis. When an end-stage renal disease patient suffers from back pain and neurological deficits, the clinician should be alerted for the spontaneous spinal epidural hematoma as well as cerebrovascular events.

The first report of acute respiratory distress syndrome (ARDS) was published in 1967, and even now acute lung injury (ALI) and ARDS are severe forms of diffuse lung disease that impose a substantial health burden all over the world. Recent estimates indicate approximately 190,000 cases per year of ALI in the United States each year, with an associated 74,500 deaths per year. Common causes of ALI/ARDS are sepsis, pneumonia, trauma, aspiration pneumonia, pancreatitis, and so on. ⋯ The clinical course of ALI/ARDS is variable with the likely pathophysiologic complexity of human ALI/ARDS. In 1994, the definition was recommended by the American-European Consensus Conference Committee, which facilitated easy nomination of patients with ALI/ARDS for a randomized, clinical trial. Here, we review the recent randomized, clinical trials of ALI/ARDS.

Case Reports
Perivascular epithelioid cell tumor (PEComa) of the liver diagnosed by contrast-enhanced ultrasonography.
Perivascular epithelioid cell (PEC) is a unique cell which expresses both myogenic and melanocytic markers, and forms PEComa. A 36-year-old woman presented with a 35 mm-diameter liver tumor. MRI showed poor fat component in the tumor. ⋯ Lateral segmentectomy of the liver was performed. Histologically, epithelioid tumor cells around the vessels were immunostained with both HMB-45 and alpha-smooth muscle actin, confirming the diagnosis of PEComa. No recurrence has been found for 18 months following the operation.

The Consolidated Standards for Reporting of Trials (CONSORT) statement was developed to improve the quality of randomized controlled trial (RCT) reports. We assessed the quality of current Japanese RCT reports by conducting a cross-sectional study to examine the extent to which they adhere to the CONSORT statement. ⋯ Our study on adherence of recent RCT reports from Japan to the CONSORT statement reveals that there is a significant need for improvement. Further investigation on the quality of RCT reports and ways to improve reporting quality is required.

A 49-year-old asthmatic woman with a history of drug allergy to aspirin and penicillin presented to the hospital with fever, dark urine, general exanthema and fatigue. Physical examination revealed jaundice. She had been taking four different over-the-counter drugs. ⋯ However, liver dysfunction with eosinophilia relapsed after discontinuing steroids. Liver biopsy revealed eosinophilic infiltration. Steroids were discontinued after the start of 6-mercaptopurine.
