Negative association between basal oxytocin and oxytocin changes after repetitive transcranial magnetic stimulation in patients with treatment-resistant depression.

Repetitive transcranial magnetic stimulation (rTMS) is a neuromodulator effective for treating depressive symptoms in patients with treatment-resistant depression (TRD). One of the multiple mechanisms for its antidepressant effects proposed is related to the hypothalamus. Oxytocin is a neuropeptide synthesized in the hypothalamus that affects human behavior and psychology, including social and affiliative behaviors, stress regulation, and fear and emotion processing.

[Investigation of the Leakage Radiation Dose Rate from an Auto Infusion Device in F-FDG PET].

Purpose: The aim of this study was to investigate the leakage radiation dose rate on the surface of an auto infusion device in F-fludeoxyglucose (FDG) positron emission tomography.

Method: We preliminary measured the radioactivity of delivery-supplied FDG drugs. Leakage radiation doses on the six (front, rear, right, left, top, and bottom) surface points of the auto infusion device were measured ninety minutes before the assay time using an energy-compensated gamma scintillation survey meter and an ionization chamber-type survey meter.

Postoperative hyperthermia-induced multiple organ failure in a child with Down syndrome: a case report.

Background: Psychological stress has been reported to cause hyperthermia. Persistent excessive hyperthermia can, in turn, cause hypercytokinemia and organ damage. We report a case of postoperative severe hyperthermia leading to a systemic inflammatory response and multiple organ failure in a child with Down syndrome.

[Suggestion of the Relative Artifact Index for Noise-independent Evaluation of the Streak Artifact].

The aim of this study was to inspect the usefulness of relative artifact index (AI), which divided artifact index (AI) by standard deviation of the noise image for noise-independent evaluation of the streak artifact in computed tomography images. A water phantom without/with a cylindrical phantom filled with diluted contrast medium was scanned with different tube voltages (100/120/140 kV) and radiation doses (5/10/20 mGy), then images were reconstructed with different kernels (B10/30/50f). AI, location parameter in Gumbel method and AI were measured in each condition and compared.

Quantitative analysis of chronological changes in the volume of flaps used for reconstruction of oral cavity defects.

Reconstruction of oral defects using flaps following resection of oral cancer has become a standard approach for restoration of oral function. The purpose of this study was to investigate chronological changes in the volume of such flaps used for reconstruction and the factors affecting flap volume. We performed a retrospective analysis of 17 patients who had undergone oral cancer resection and reconstruction with flaps.

Extra-hepatic feeding arteries of hepatocellular carcinoma: An investigation based on intra-arterial CT aortography images using an angio-MDCT system.

Objectives: We investigated the frequencies and factors associated with the presence of extra-hepatic feeding arteries (EHFAs) of hepatocellular carcinoma (HCC) using intra-arterial CT aortography images.

Methods: A total of 173 patients with HCC who underwent transarterial chemoembolization (TACE) in our institution between January 2013 and March 2015 were enrolled. The types of EHFAs were evaluated by CT aortography images using an apparatus that combines multidetector-row computed tomography and angiography system.

Accurate and rapid identification of feeding arteries with multidetector-row angiography-assisted computed tomography for transarterial chemoembolization for hepatocellular carcinoma.

Background: Transarterial chemoembolization (TACE) is an important treatment modality for hepatocellular carcinoma (HCC). Accurate identification of feeding arteries and catheterization are necessary for achieving treatment efficacy, especially with selective TACE. However, this often requires multiple imaging studies.

[Evaluation of docetaxel, CDDP and 5-FU combined therapy as second-line chemotherapy for esophagus cancer].

The combined therapy of docetaxel (70 mg/m(2), day 1), CDDP (80 mg/m(2), day 1) and 5-FU (800 mg/m(2), day 1-5) is used as second-line chemotherapy for esophagus cancer. First-line chemotherapy for 32 advanced squamous cell carcinomas of the esophagus is not effective, and early recurrences after chemotherapy were examined. Pretreatment surgery was used in 20 cases,radiation therapy in 19 and chemotherapy by 3.

Primary omental-mesenteric myxoid hamartoma of the mesoappendix incidentally detected after abdominal trauma in a child: report of a case.

A 14-year-old boy was brought to our hospital with abdominal pain and nausea after suffering a blow to the abdomen. A mass was felt in the right hypogastrium, and the patient was hospitalized for possible hematoma resulting from the abdominal trauma. Initially, we treated him conservatively and observed his course, but on the 20th day after trauma, enhanced computed tomography showed that the area of strong enhancement in the tumor was unchanged.
