BACKGROUND Various Japanese versions of the Epworth Sleepiness Scale (ESS) have been used, but none was developed via standard procedures. Here we report on the construction and testing of the developer-authorized Japanese version of the ESS (JESS). METHODS Developing the JESS involved translations, back translations, a pilot study, and psychometric(More)
Obstructive sleep apnoea is common in patients with diabetes. Recently, it was reported that short sleep duration and sleepiness had deleterious effects on glucose metabolism. Thereafter, several reports showed relationships between glucose metabolism and obstructive sleep apnoea, sleep duration or sleepiness. But the interrelationships among those factors(More)
PURPOSE Obesity has been associated with obstructive sleep apnea and hepatic steatosis. We investigated the effects of obstructive sleep apnea and treatment with nasal continuous positive airway pressure (CPAP) on serum aminotransferase levels in obese patients. METHODS We studied 40 obese men with obstructive sleep apnea syndrome. None had hepatitis B(More)
STUDY OBJECTIVES After nasal continuous positive airway pressure (nCPAP) treatment, several symptoms such as hypersomnolence, daytime fatigue, and impaired concentration improve in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). A variability of perception of pretreatment sleepiness (response-shift phenomenon) experienced in OSAHS patients(More)
STUDY OBJECTIVES To examine (1) the prevalence of home-monitored sleep-disordered breathing (SDB) and obstructive sleep apnea syndrome in a Japanese working population and (2) whether home monitoring with a type 3 portable monitor and actigraphy can produce reliable data to analyze SDB in usual lifestyles. METHODS A cross-sectional survey using a(More)
BACKGROUND Dyslipidemia is often comorbid with obstructive sleep apnea (OSA), but few population-based studies have investigated their relationship. Short sleep duration is associated with hypertension and diabetes; however, its association with dyslipidemia is not well known. We investigated relationships among OSA, sleep duration, and the lipid profile in(More)
BACKGROUND Severe obstructive sleep apnea (OSA), metabolic syndrome (Mets) and short sleep duration are all risk factors for cardiovascular events. There has been no report which has investigated this relationship in an age- and BMI-matched population-based study. The prevalence of OSA in Mets subjects has not been established, although the converse (i.e.,(More)
STUDY OBJECTIVES Hypoxemia increases corrected QT dispersion (QTcD), which is the difference between the maximum and minimum QT intervals and is a strong risk factor for cardiovascular mortality. The aim of this study was to investigate the QTcD in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS), and the relationship between the QTcD and(More)
A 16-year-old male with exertional heat stroke (EHS) had extensive hepatocellular damage, severe rhabdomyolysis, renal failure, and coma. Hemodiafiltration was started on day 2 and living donor liver transplantation was performed on day 3. He received continuous mechanical ventilation with intubation before and after the surgery. As his mental status(More)

Metastatic lesions from renal cell carcinoma are commonly recognized in the lung and bone, however, thyroid metastasis has rarely been reported in the literature. We present herein a case of a man with lung and thyroid metastatic tumors from renal cell carcinoma. Although making a preoperative diagnosis of thyroid metastasis is difficult because there is no(More)
