A 63-year-old Japanese woman with a history of pemphigus was referred to us for abnormal findings of dynamic abdominal CT where three aneurysms of splenic artery and pancreaticoduodenal artery, celiac axis compression, and gall stone. Superior mesenteric artery supplied hepatic arterial flow via pancreaticoduodenal artery. Avoiding transarterial embolization to prompt arterial ischemia of liver/pancreas head/duodenum, she laparotomically underwent cholecystectomy, splenectomy, transection of median arcurate ligament, and ligation of splenic and inferior pancreaticoduodenal artery all at once...

BACKGROUND: Computed tomography (CT)-guided needle biopsy is a well-established and dependable procedure for the diagnosis of pulmonary lesions. Some tissue biopsy samples have loose cohesion and disintegrate into tiny pieces before formalin fixation. The purpose of this study was to assess the association between the fresh macroscopic appearance of samples obtained using CT-guided needle biopsy and the clinicopathological features of non-small cell lung cancer (NSCLC). METHODS: A total of 111 patients who underwent CT-guided lung needle biopsy at Osaka City University Hospital between May 2009 and May 2013 were enrolled...

BACKGROUND: Mesenchymal stromal cells (MSCs) have been intensively investigated in regenerative medicine. Among the different types of MSCs, adipose tissue-derived stromal cells (ASCs) can be obtained with relatively less invasive techniques. Since ASC administration is a candidate strategy for the treatment of refractory diseases including pulmonary fibrosis, we investigated whether intratracheal injection of ASCs had therapeutic potential against bleomycin (BLM)-induced lung injury in rats...

BACKGROUND: Non-psychotic delusions are reported to be associated with depression and anxiety. When these delusions occur in high-functioning pervasive developmental disorder (HFPDD) children, they are often misdiagnosed as schizophrenia and have consequently been studied less. This study has three goals: to investigate the prevalence of non-psychotic delusions in HFPDD children, to test the hypothesis that HFPDD children are more likely to have non-psychotic delusions than non-HFPDD children, and to test the hypothesis that non-psychotic delusions are associated with depression and anxiety...

BACKGROUND: Pediatricians sometimes see patients with severe aseptic meningitis and prolonged fever or severe headache, or both. This condition generally has a good prognosis and is usually treated with supportive therapy. However, there is neither guideline nor consensus for the treatment of patients with severe aseptic meningitis. Here, we investigated the relationship between disease severity and biomarkers. METHODS: The subjects were 32 children aged 0 to 14 years, 23 of whom had aseptic meningitis and 9 of whom were meningitis-free controls...

BACKGROUND: Esophageal anastomotic leakage is one of the most fatal complications after esophagectomy and increases the hospitalization length. We aimed to identify a convenient clinical marker of anastomotic leakage in the early postoperative period. METHODS: In total, 108 patients who underwent esophagectomy were retrospectively screened, and 96 were used to validate the overall results. All 108 patients underwent physical examinations and determination of their white blood cell count, C-reactive protein level, platelet count, fibrinogen level, fibrin degradation product level, and antithrombin III level until postoperative day 6...

BACKGROUND: Highly concentrated carbon dioxide (GO2) is useful for treating ischemic diseases. Therefore, we investigated whether treatment with a few micrometers of CO2 molecules, atomized by two fluid nozzles (CO2 mist), could attenuate the development of right ventricular (RV) dysfunction in pulmonary hypertensive rats. METHODS: Six-week-old male Wistar rats were divided into three groups: one that received injected saline; a second that received subcutaneous monocrotaline (MCT; 60 mg/kg) without treatment (PH-UT) group; and a third that received MCT with CO2 mist treatment (PH-CM) after MCT administration...

BACKGROUND: Varenicline has been reported to achieve high rates of smoking cessation. It remains undetermined whether varenicline therapy improves vascular function in smokers. METHODS: Consecutive Seventy-two smokers (age 57 ± 12 years) who succeeded in complete smoking cessation and 46 normal healthy volunteers (age 24 ± 3 years) with no cardiovascular risk factors were enrolled into this study. Vascular function and structure were assessed by flow-mediated dilation (FMD), nitroglycerin-induced vasodilation, and brachial artery intima-media thickness (baIMT) at baseline and 20 weeks after the initiation of varenicline therapy in smokers...

BACKGROUND: The presence of cardiac involvement in sarcoidosis, a multisystem granulomatous disease of unknown etiology, is associated with very poor prognosis. Therefore, early detection of cardiac sarcoidosis (C-sar) is very important for effective treatment. Recently, the value of late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR), which allows visualization of even minute amounts of myocardial damage, has been emphasized in diagnosing C-sar. Although the presence of LGE has been added as a minor criterion for diagnosing C-sar in the most recent Japan Ministry of Health and Welfare (JMHW) guidelines, its clinical utility remains unknown...

A 33-year-old Japanese man who had suffered from liver cirrhosis due to hepatitis C virus (HCV) underwent living related liver transplantation (LRLT). The allograft was given by his brother, who was healthy with no history of hepatitis or hepatic virus infection. After LRLT, the patient's hepatitis C recurred. Liver biopsy revealed chronic viral hepatitis and no allograft rejection such as shown by portal lymphocytic infiltration or mild bridging fibrosis. Interferon and ribavirin were administered, and sustained viral response (SVR) was obtained...

BACKGROUND: Aspiration pneumonia (AP) following cerebral infarction (CI) has been considered as one of its most serious complications. Nevertheless, there are no reports on the association between the type or location of CI and the incidence of AP. In addition, the association between dysphagia, which leads to aspiration, and the type or location of CI has never been investigated. Therefore we hypothesized that the laterality of CI affects the development of both dysphagia and AP. METHODS: We performed a retrospective cohort study to examine the association between the laterality of CI and the incidence of dysphagia and AP in 133 patients...

BACKGROUND: The relationship between focal brain atrophy and delusions in patients with Dementia of the Alzheimer's Type (DAT) is not well understood. Few studies have been reported on the association between medial temporal atrophy (MTA) and persecutory delusions in patients with DAT. We investigated the relationship between MTA and persecutory delusions in patients with DAT using voxel-based specific regional analysis system for Alzheimer's disease (VSRAD) advance software, which allows us to quantify the laterality and the degree of MTA on magnetic resonance imaging (MRI) scans...

BACKGROUND: Studies have shown that children with pervasive developmental disorder (PDD) have high rates of sensory hypersensitivity. In addition, a few recent studies suggested that sensory hypersensitivity was related to anxiety or depression. However, most studies had methodological limitations because they included children with mental retardation and did not examine broadband psychopathology. Therefore, the purpose of this study was to examine the prevalence of sensory hypersensitivity in children with high-functioning PDD (HFPDD) and the correlation among sensory hypersensitivity, various characteristics, and broadband psychopathology...

BACKGROUND: Forced oscillation technique (FOT) is increasingly used to obtain much information on the state of the respiratory system. However, there are little data about FOT parameters on methacholine provocation test in adult asthma. This study was designed to determine the physiological implications of FOT parameters during methacholine provocation and analyze the major contributing factors to airway hyperresponsiveness (AHR) in asthma. METHODS: Spirometry and FOT were performed in 22 asthmatic patients and 21 normal control subjects before and after provocation with a maximal dose of methacholine...

In this report, the magnetic resonance imaging (MRI) appearance of struma ovarii (SO) in a patient who underwent diffusion-weighted imaging (DWI) of the pelvis and subsequent histological analysis is described. The solid portion of SO showed a high apparent diffusion coefficient (ADC) value, indicating unrestricted diffusion, and each loculus of SO showed different ADC values due to the different viscosity of the cyst contents in each loculus. These unique and characteristic DWI findings may serve as a helpful sign in making the correct diagnosis of SO when DWI findings are interpreted in conjunction with conventional MRI findings...

A 39-year-old male with elevated serum transferases consulted our hospital in September 2010. Since 1999, he had worked at a printing company using organic solvents. Cholangiography revealed stenosis of the left hepatic duct with peripheral dilation, stricture of the right hepatic duct, and irregularity of the extrahepatic bile duct. As a preoperative diagnosis of sclerosing cholangitis and cholangiocarcinoma was made, extended left hepatectomy with resection of the extrahepatic bile duct and anastomosis of the anterior and posterior branches of the bile duct and the jejunum (Roux-en Y reconstruction) were performed...
