Diagnostic and therapeutic role of endoscopic retrograde pancreatography and stent placement for grade IV blunt pancreatic trauma: A case report.

Pancreatic trauma involving ductal injury is rare but is associated with high morbidity and mortality. The benefit of endoscopic retrograde pancreatography and stent placement is unclear because there are only a few case reports on endoscopically treated pancreatic duct transection at the pancreatic head. We report a rare case of grade IV pancreatic trauma successfully treated with endoscopic pancreatic stent, which we believe makes significant contribution to the existing literature.

[A Case of Carcinoma Associated with an Anal Fistula Repaired Using a Hatchet Flap after Neoadjuvant Chemoradiotherapy].

The patient was a 53-year-old man who complained of perianal pain. He had a 20-year history of an anal fistula. There was a 10 cm tumor with mucin-like discharge on the left side of the anus.

[HER2-Positive Advanced Gastric Cancer with Disseminated Intravascular Coagulation and Diffuse Bone Marrow Carcinomatosis Successfully Treated with S-1/Trastuzumab Chemotherapy--A Case Report].

Trastuzumab, a humanized monoclonal antibody against human epidermal growth factor receptor 2 (HER2), has been proven to result in a survival benefit for the treatment of patients with HER2-positive advanced gastric cancer (AGC). However, data are lacking for the treatment of those with disseminated intravascular coagulation (DIC) and diffuse bone marrow carcinomatosis. A 77-year-old woman presented with back pain and fatigue since 2 months.

Analysis of side population cells derived from dental pulp tissue.

Aim: To investigate the characteristics of side population (SP) cells derived from the dental pulp of young and aged rats.

Methodology: Maxillary and mandibular incisors were extracted from 5-week-old (young) rats and 60- to 80-week-old (aged) rats. Coronal pulp tissue was removed mechanically, and single-cell suspensions were prepared using collagenase and dispase.

Influence of the length of the loading period after placement of orthodontic mini-implants on changes in bone histomorphology: microcomputed tomographic and histologic analysis.

Purpose: The recent use of microcomputed tomography (microCT) has made it possible to analyze qualitative bone morphology at the implant surface and in the peri-implant region. The purpose of this study was to evaluate histomorphometric changes around the implant-bone interface after placement of mini-implants using three-dimensional microCT analysis and to compare the stability of the implants after immediate and early loads were applied.

Materials And Methods: Forty-eight orthodontic mini-implants (ORLUS, Ortholution) were placed in the mandibular buccal jawbone of eight beagle dogs.
