Serous endometrial carcinoma metastatic to the sigmoid colon masquerading as a primary colon cancer detected by bowel obstruction.

Background: The majority of colorectal malignancies are primary tumors. Secondary tumors are rare, and colorectal metastasis from endometrial carcinoma is exceptionally uncommon. We report a case of serous endometrial carcinoma that metastasized to the sigmoid colon, initially presenting as a primary colon carcinoma due to bowel obstruction.

Pathophysiology and surgical outcomes of patients with fungal peritonitis from upper gastrointestinal tract perforation: a retrospective study.

Purpose: To compare the pathophysiology and surgical outcomes of emergency surgery for upper gastrointestinal tract perforation with and without fungal peritonitis and identify the risk factors for fungal peritonitis.

Methods: The subjects of this retrospective study were patients with upper gastrointestinal perforation and peritonitis who underwent emergency surgery at a single medical center in Japan. The patients were allocated to two groups according to the presence or absence of fungal peritonitis: group F and group N, respectively.

Features of Microcalcifications on Screening Mammography in Young Women.

Background: There is no decrease in the number of breast cancer deaths if screening mammography is performed in women aged <40 years. However, NCCN guidelines recommend screening mammography in young women at risk of hereditary breast cancer. Therefore, more accurate screening mammography for young women is needed.

Anastomosis Procedure through an Inguinal Hernia Incision in Simultaneous Laparoscopic Anterior Resection and Inguinal Hernia Repair.

For laparoscopic anterior resection, an additional small incision is usually placed in the left lower quadrant or the suprapubic portion. As a left inguinal hernia incision is close to both the left lower quadrant and the suprapubic portion, such an incision can be used for anastomosis in laparoscopic anterior resection, without additional incisions. We report a laparoscopic anterior resection using a left inguinal hernia incision for colorectal anastomosis, in a patient who underwent concomitant left inguinal hernia repair.

Diffusion properties of point defects in barium strontium titanate thin films.

The relationship between the diffusion behavior of hydrogen and the electrical properties of (Ba, Sr)TiO3 (BST) thin-film capacitors was investigated using thermal desorption spectroscopy and secondary ion mass spectroscopy analyses. It has been clearly shown that the frequency dependence of the complex impedance profile of the BST thin-film capacitors could be successfully represented by two parallel resistor-capacitor (RC) electrical equivalent networks in series correlated with the distribution of the hydrogen, namely, the Pt/BST interface region with the influence of hydrogen and the BST bulk region without the influence of hydrogen. However, the I-V properties of the BST thin-film capacitors could be determined almost from the hydrogen atoms existing at the Pt/BST interface.

Mutagenicity of water-soluble FePt nanoparticles in Ames test.

A mutagenicity test was conducted on water-soluble FePt nanoparticles capped with tetramethylammonium hydroxide in a bacterial reverse mutation assay using Salmonella typhimurium strains TA98, TA100, TA1535 and TA1537, and Escherichia coli strain WP2uvrA/pKM101, with and without metabolic activation by S9 mix in the preincubation method. Mutagenicity was weakly positive in the TA100 strain without S9 mix (maximum specific activity was 61.6 revertants/mg), but negative in other cases.

Mesorectum amputation technique for laparoscopic anterior resection.

The objective of this study was to assess our original procedure, the cutting off method (COM), where the rectum and mesorectum are cut off with an autosuture device simultaneously in laparoscopic anterior resection. From 2001 to 2003, laparoscopic anterior resection was performed in 21 patients at our institution using the COM (n = 14) and trimming method (TM; n = 7). We reviewed the medical records for operative duration, intraoperative blood loss, and postoperative complications.
