Information on obstructive sleep apnea-hypopnea syndrome (OSAHS) in Japan has been limited. The purposes of this clinical study were to evaluate the demographic characteristics of Japanese OSAHS patients and to assess how demographic factors are associated with OSAHS severity. We analyzed 3,659 OSAHS patients who underwent polysomnographic evaluation between January 2000 and December 2004 at 11 hospitals in Niigata Prefecture, Japan. Data consisted of apnea-hypopnea index (AHI) and demographic characteristics, including sex, age, and body-mass index, for statistical analysis. Levels of obesity were classified according to the WHO criteria. The male-to-female patient ratio for OSAHS was 4.6, and male patients presented more severe OSAHS than female patients. High AHI and a high proportion of moderate to serious OSAHS (AHI > or = 15) were found among the patients in their 30s, as well as female patients in their 70s and male patients in their 80s. The AHI and the proportion of moderate-to-serious OSAHS (AHI > or = 15) were greater in patients classified as underweight than in normal weight patients. In conclusion, there is a higher male predominance in the prevalence of OSAHS, and in both sexes, the results suggest different pathophysiological mechanisms of deteriorating OSAHS between adults under age 55 and adults 55 years or over. In addition, underweight patients exhibit more severe OSAHS than normal weight patients. 相似文献

BACKGROUND: In Japan, prophylactic hemodialysis has been considered useful for preventing contrast-induced nephropathy (CIN). METHOD AND RESULTS: To assess whether hemodialysis prevented CIN, 391 patients (age: 69 +/- 8 years, 63 females) with chronic renal insufficiency (CRI, serum creatinine level (Scr) > or = 1.3 mg/dl) who underwent cardiac catheterization, were retrospectively analyzed. Patients were divided into 3 categories based on Scr: L (1.3 > or = Scr < 2.0 mg/dl, n = 332); M (2.0 > or = Scr < 3.0 mg/dl, n = 49); and H (Scr > or = 3.0 mg/dl, n = 10). To prevent CIN, 35 category M patients and all category L patients received hydration alone, whereas 14 category M patients and all category H patients received hemodialysis. CIN developed in 48 patients. The incidence of CIN in category H was significantly higher than that in category L or M (H, 40% vs L, 11% or M, 16% (p < 0.05)). In category M patients treated with hemodialysis, Scr increased from 2.4 +/- 0.3 to 3.0 +/- 0.5 mg/dl (p < 0.05) within 7 days, and 29% of patients developed CIN. However, in category M patients who did not receive hemodialysis, the Scr did not change (pre, 2.3 +/- 0.2 mg/dl to post, 2.2 +/- 0.4 mg/dl), and the incidence of CIN was 11%. CONCLUSION: Prophylactic hemodialysis for CRI patients undergoing cardiac catheterization does not prevent CIN. 相似文献

A microsurgical technique was used in performing anterior hepatic segmentectomy and pancreatoduodenectomy with reconstruction of the posterior hepatic artery in a 64-year-old man with widespread bile duct cancer from the intrapancreatic bile duct over the hepatic hilus. The anterior hepatic artery was obviously involved and the posterior hepatic artery just behind common hepatic duct was very close to the cancer. Microsurgical anastomosis between the remnant gastroduodenal artery and the posterior hepatic artery at the hepatic hilus made it possible to preserve the posterior segment of the liver and to perform a curative resection of the cancer. The patient had pyrexia because of suprahepatic abscess after the operation, but the abscess drained spontaneously. Postoperative arteriogram showed neither obstruction nor kinking of the reconstructed artery. He was discharged 2 months after surgery and has been enjoying a normal quality of life for 10 months since, with no signs of recurrence. It is suggested that a microsurgical technique is useful for performing an accurate anastomosis with good patency that allows not only a safe but also a highly curative operation for advanced bile duct cancer. 相似文献

Objective
Carotid artery stenting (CAS) is a well-accepted treatment for atherosclerotic stenosis of carotid arteries. Since the occurrence of distal embolization with CAS is still a major concern embolus protection devices (EPD) are usually employed during the procedure. We examined two types of embolus protection filters (Angioguard XP (AG); Filterwire EZ (FW)) and evaluated the function. Thus, the filter was examined postoperatively and the cause of intraoperative flow impairment was evaluated.Materials and methods
CAS was performed for 54 patients with carotid artery stenosis (55 lesions: 25 AG; 27 FW; 3 others). After completing CAS the filter membrane was stained with hematoxylin-eosin (HE) solution and removed from the filter strut. Once mounted on a glass slide the filter was evaluated under a microscope. The area occupied with debris was measured and the relationship to intraoperative flow impairment was evaluated. Furthermore, the relationship between perioperative ischemic complications and intraoperative flow impairment was statistically analyzed.Results
Microscopic observation of the slide revealed the pore density of the FW was 1.5 times higher than that of the AG and the filter area of the FW was 2.5 times wider than than the AG. HE staining facilitated characterization of the debris composition. The area occupied with debris was significantly more in the AG (0.241?±0.13 cm2) than in the FW (0.129?±0.093 cm2). Thus, fibrin was significantly more precipitated in the AG. Flow impairment occurred in 6 AG cases (24.0 %) and 4 FW cases (14.8 %). It was induced by filter obstruction in the AG and by vasospasms in the FW. Three cases treated with AG (12.0 %) were complicated with cerebral infarction and all of them were related to flow impairment. One FW case (3.7 %) was complicated with cerebral infarction in presence of preserved flow throughout the intervention.Conclusion
Filter function is different according to each design. The cause of flow impairment was attributable to filter obstruction in the AG group and to vasospasms in the FW group. Filter obstruction tends to result in cerebral infarction. 相似文献197.

The purpose of this study was to analyze passive motion of the para- and retropharyngeal space (PRS) during swallowing using dynamic magnetic resonance imaging (MRI). We conducted a preliminary study involving 30 healthy volunteers who underwent dynamic MRI. Consecutive MRI axial images were obtained by examining the plane parallel to the hard palate at the level of the anterior inferior corner of C2. Anterior displacement of the posterior pharyngeal wall (PPW) was measured as a motion index of pharyngeal contraction. The displacement and internal angle of the bilateral external and internal carotid arteries (ECA and ICA) and the bilateral centroids of the PRS area, as well as the increase in PRS area, were calculated at rest and at maximum pharyngeal contraction. In most participants, the bilateral ECA, ICA, and centroids were anterointernally displaced by pharyngeal contraction. The normalized ECA displacement (r = 0.64, r 2 = 0.41), normalized ICA displacement (r = 0.60, r 2 = 0.37), and normalized centroid displacement (r = 0.43, r 2 = 0.19) were more than moderately positively correlated with the normalized PPW displacement. The normalized PRS area increase (r = 0.35, r 2 = 0.12) was weakly positively correlated with the normalized PPW displacement. These results revealed that PRS area increased as the ECA and ICA were drawn anterointernally via its passive motion by pharyngeal contraction. 相似文献
