We presented a 38-year-old woman suffering from acute cerebral infarction due to arteritis limited to bilateral internal carotid arteries without a condition of giant cell arteritis or granulomatosis with polyangitis. Our case is unprecedented and characterized by a young woman with wall enhancement in the internal carotid arteries on contrast-enhanced magnetic resonance imaging (MRI), therapeutic effects of steroids, and positive status for human leucocyte antigen-B39, -B51 and -DR4. These disease characteristics were not in accordance with existing diagnostic criteria of vasculitis, such as Takayasu's arteritis, giant cell arteritis, granulomatosis with polyangiitis, and Behcet's disease...

It is difficult to directly observe glottal airflow velocity just above the glottis due to sensor size requirements and limited accessibility. We developed a miniature hot-wire probe and flexible fiberscopic high-speed imaging system for human examinations. Simultaneous direct measurement of glottal airflow velocity, subglottal pressure, and vocal fold vibration was achieved in a patient who was treated with a T-tube for tracheal stenosis. Airflow velocity changes at the anterior midline of the vocal folds were synchronized with subglottal pressure changes during each phonation cycle...

We report the case of a man in his 70s who suffered from intestinal infarction caused by acute portal vein and mesenteric vein thrombosis (PVMVT). Combination therapy with percutaneous transcatheter thrombectomy and surgical bowel resection was successfully performed, and a satisfactory outcome was achieved. Intestinal infarction caused by PVMVT can be fatal and has a high mortality rate even if surgical resection is performed. The combination therapy of interventional radiology and surgery might be a safe and effective method for patients with this life-threatening condition...

BACKGROUND: Sepsis is a syndrome triggered by endotoxin lipopolysaccharide (LPS) during bacterial infection. Sepsis sometimes recurs, with the second sepsis giving rise to a different phenotype because of disease modification by the preceding sepsis. Such a protective modification is called a preconditioning (PC) effect. PC is an endogenous protective mechanism by which sublethal damage confers tolerance to a subsequent lethal load. Oxidative stress is one of the important pathogenetic mechanisms that occur in sepsis...

BACKGROUND: For patients with reactivation of human cytomegalovirus (CMV), a highly sensitive and accurate CMV quantification system is essential to monitor viral load. METHODS: We constructed a real-time detection PCR (RTD-PCR) system for CMV DNA and evaluated its linearity, lower detection limit, dynamic range and accuracy using two CMV standards. We used 219 clinical samples derived from 101 patients to compare the system with the pp65 antigen test. RESULTS: The 95% detection limit was determined to be 556 IU/mL (95% CI, 440-797 IU/mL), and the quantification range was between 10(2) and 10(6) copies or IU/mL (r = 0...

BACKGROUND: Vitamin E (VE, α-tocopherol) is a fat-soluble vitamin and is well known as an antioxidant. A deficiency in VE induces oxidative stress in the brain and causes motor and memory dysfunction. The consumption of a VE-rich diet has been given much attention in recent years, in regards to anti-aging and the prevention of age-related neuronal disorders. METHODS: A VE-deficient mouse model was prepared by feeding the animals a diet lacking VE. In addition, to evaluate the effect of VE-containing rice bran (RB) on VE deficiency, a diet including RB was also provided...

Umbilical melanoma is extremely rare. Among the past English reports on umbilical melanoma, there are only 8 reports in which histopathology was described in detail, and there has been no report with a review of the histopathology of previously reported cases. We experienced a case of umbilical melanoma and reviewed previously reported cases including our case. Because of the anatomical location, it is difficult to become aware of the umbilical melanoma unless there are some concomitant symptoms such as discharge or swelling...

BACKGROUND: Breast ultrasound findings regarding tumor margins are crucial in judging whether a tumor is malignant or benign. However, the relationships between the margins and clinicopathological characteristics remain largely unknown. In this study, we examined the clinicopathological characteristics of patients with invasive ductal carcinoma whose ultrasound images showed either well-defined and rough or indistinct margins. METHODS: Of all consecutive patients diagnosed with invasive ductal carcinoma at the Division of Breast and Endocrine Surgery of Tottori University Hospital from January 2012 to December 2014, 122 patients whose ultrasound images showed either "well-defined and rough" or "indistinct" tumor margins were included in this study...
