Immunomodulating Activity of Agaricus brasiliensis KA21 in Mice and in Human Volunteers

We performed studies on murine models and human volunteers to examine the immunoenhancing effects of the naturally outdoor-cultivated fruit body of Agaricus brasiliensis KA21 (i.e. Agaricus blazei). Antitumor, leukocyte-enhancing, hepatopathy-alleviating and endotoxin shock-alleviating effects were found in mice. In the human study, percentage body fat, percentage visceral fat, blood cholesterol level and blood glucose level were decreased, and natural killer cell activity was increased. Taken together, the results strongly suggest that the A. brasiliensis fruit body is useful as a health-promoting food

Anastomotic Recurrence due to Tumor Implantation using the Double Stapling Technique after Curative Surgery for Sigmoid Colon Cancer

Recurrence at the site of a stapled anastomosis is generally believed to result from the luminal implantation of viable cancer cells during stapling. We report a 57-year-old woman who underwent radical surgery for sigmoid colon cancer and developed anastomotic recurrence ten months after the initial operation. Her serum carcinoembryonic antigen (CEA) levels were within normal limits during the postoperative follow-up. The patient subsequently underwent a partial colon resection for the anastomotic recurrence. The clinicopathological findings revealed that possible tumor cell implantation caused the recurrence. We encountered a case of anastomotic recurrence due to possible tumor implantation after curative surgery for sigmoid colon cancer. Follow-up colonoscopy was more helpful for the diagnosis of anastomotic recurrence than CEA monitoring

Strangulation Caused by a Small Bowel Epiploic Appendage: Report of a Case

While many recent cases of colonic epiploic appendage causing acute abdomen have been reported, such appendages of the small bowel are extremely rare. We present a 59-year-old woman in whom a small bowel epiploic appendage caused volvulus. She presented with abdominal pain and vomiting in the absence of previous abdominal operations. A diagnosis of small bowel obstruction from strangulation was made. Laparotomy disclosed bloody peritoneal fluid and a closed loop of strangulated small intestine. An adherent band composed of an epiploic appendage and intestine had completely encircled a loop of jejunum, leading to obstruction. This band was released, and approximately 80 cm of gangrenous bowel was resected. Four epiploic appendages 5–6 cm in length were attached to the ileum at the mesenteric border, beginning at a point 70 cm proximal to the terminal ileum

Reliability and validity of the patient disability-oriented diagnostic nomenclature system for prosthetic dentistry

Purpose: The Japan Prosthodontic Society (JPS) has proposed a new diagnostic nomenclature system (DNS), based on pathogenesis and etiology, to facilitate and improve prosthodontic treatment. This systemspecifies patient disability and the causative factor (i.e. ‘‘B (disability) caused by A (causative factor)’’). The purpose of this study was to examine the reliability and validity of this DNS. Study selection: The JPS Clinical Guideline Committee assessed mock patient charts and formulated disease names using the new DNS. Fifty validators, comprising prosthodontic specialists and dental residents, made diagnoses using the same patient charts. Reliability was evaluated as the consistency of the disease names among the validators, and validity was evaluated using the concordance rate of the disease names with the reference disease names. Results: Krippendorff’s α was 0.378 among all validators, 0.370 among prosthodontic specialists, and 0.401 among dental hospital residents. Krippendorff’s α for 10 validators (3 specialists and 7 residents) with higher concordance rates was 0.524. Two validators (1 specialist and 1 resident) with the highest concordance rates had a Krippendorff’s α of 0.648. Common disease names had higher concordance rates, while uncommon disease names showed lower concordance rates. These rates did not show correlation with clinical experience of the validator or time taken to devise the disease name. Conclusions: High reliability was not found among all validators; however, validators with higher concordance rates showed better reliability. Furthermore, common disease names had higher concordance rates. These findings indicate that the new DNS for prosthodontic dentistry exhibits clinically acceptable reliability and validity
