Background/aim: Elevated blood fibronectin (FN) levels have been observed in various cancers; however, their significance remains controversial. Herein, we measured the levels of sialyl-fibronectin (S-FN), a type of FN secreted by tumor cells, and investigated whether blood S-FN secretion is associated with recurrent metastasis and epithelial-mesenchymal transition (EMT).

Patients And Methods: An ELISA system recognizing S-FN was constructed, and the amount of S-FN in blood samples from 63 patients with thyroid carcinoma was measured.

Introduction: Recently, single-incision laparoscopic cholecystectomy has been accepted as an alternative to conventional laparoscopic cholecystectomy. The aim of this study was to retrospectively evaluate the safety and feasibility of unique gallbladder retraction methods using an ENDOLOOP® (Ethicon, Tokyo, Japan) and Lapaherclosure™ (Hakko Medical, Tokyo, Japan).

Materials And Surgical Technique: From May 2013 to April 2015, 77 patients underwent single-incision laparoscopic cholecystectomy with this retraction technique.

While respiratory epithelial involvement has been described in several cases, lesions in the colon epithelium have never been reported. We describe a 57-year-old Japanese woman with PNP who had many aphthae-like erosions on the colon epithelium, in addition to typical mucocutaneous PNP lesions.

We describe a 54-year-old man with hepatitis C virus (HCV) infection-associated cryoglobulinemia type III. The patient had suffered from cold-induced urticaria that left purpuric eruptions up to 1 cm in diameter, intermittent migratory joint pain for seven years and mild liver dysfunction for nine years. Hemophilia A was diagnosed when the patient was 26 years old, and he was then given infusions of factor VIII for a short time.
