Motion Analysis of the Trapeziometacarpal Joint Using Three-dimensional Computed Tomography.

Background: Zancolli theorized that the first metacarpal bone axially rotates on the semispheroidal part of the trapezium, which is controlled by ligaments. This study used three-dimensional computed tomography (3D-CT) to describe the motion of the first metacarpal bone on the trapezium.

Methods: 3D-CT images were taken of the left hand of 30 healthy volunteers (mean age [Formula: see text] years, 15 men and 15 women).

Blunt thyroid trauma with acute hemorrhage and respiratory distress.

We report a rare event of acute hemorrhage into a thyroid adenoma after blunt trauma and causing respiratory distress. A 65-year-old woman fell and hit the left side of her anterior neck without any other injuries. The next day, she suffered from severe dyspnea and respiratory distress, and visited a community hospital.

Usefulness of an estimation of physiologic ability and surgical stress (E-PASS) scoring system to predict the incidence of postoperative complications in gastrointestinal surgery.

Surgical intervention induces various host responses to maintain homeostasis. When postoperative inflammation is intense and persists for a long time, postoperative complications may occur, sometimes developing into multiple organ failure. Therefore, it is very important to assess surgical stress and predict the risk of morbidity and mortality.

Successful excision of a congenital, prenatally diagnosed fibrosarcoma involving the entire right ovary.

This report describes a congenital fibrosarcoma (CFS) of the ovary presenting as an abdominal mass on prenatal ultrasonography. Few cases of intrauterine CFS have been reported to date. When CFS develops prenatally, it usually grows rapidly, and resection is difficult at birth.

FTY720 reduces T-cell recruitment into murine intestinal allograft and prevents activation of graft-infiltrating cells.

Background: Effective immunosuppression is a critical determinant of graft survival in small-bowel transplantation (SBTx). The present study was designed to determine the potency of FTY720, a newly synthesized immunosuppressant, in rat SBTx and examine the phenotype of graft-infiltrating cells to evaluate its effect on intestinal allografts.

Materials And Methods: A segment of intestine of Dark Agouti rats was transplanted heterotopically into Lewis rats.

Follow-up studies of anorectal malformations after posterior sagittal anorectoplasty.

Background/purpose: There are few follow-up studies comparing posterior sagittal anorectoplasty (PSARP) with conventional procedures for patients with anorectal malformations (ARM). The authors have examined retrospectively postoperative anorectal function of patients with ARM treated with PSARP compared with those treated with conventional methods.

Methods: Anorectal function in 23 patients with high and intermediate type anorectal malformations (PSARP group), who underwent PSARP more than 4 years previously, were assessed by Kelly's clinical scoring system and objective studies.
