Fifth carpometacarpal fracture dislocations fixed with Meta-HUS®: a series of 31 cases.

Fracture dislocations of the fifth carpometacarpal are usually treated by percutaneous K-wires despite occasional complications: displacement, stiffness, malunions, and arthritis. Our aims were to evaluate the use of locked K-wire fixation for these fracture dislocations. Our series includes 31 fracture dislocations, five extra-articular and 26 articular, 21 of which were at the base of the metacarpal, four at the hamate, and one involving both the hamate and the metacarpal.

Percutaneous fixation of first metacarpal base fractures using locked K-wires: a series of 14 cases.

The treatment of choice for first metacarpal base fractures is surgical. Open fixation is stable but causes tendinous adhesions. Percutaneous fixation is minimally invasive but is often followed by secondary displacement.

Dysregulation of gastric H,K-ATPase by cigarette smoke extract.

Aim: To test whether the expression and activity of H,K-ATPase in parietal cells would be affected by cigarette smoke extract.

Methods: Extracts of cigarette smoke were administered into mice by gastric gavage (5 mg/kg body weight/day) for 3 d or in drinking water for 7 or 14 d. For the latter, each day a mouse consumed 5 mL water containing extracts of two cigarettes, on average.
