Comminuted Dorsal Ulnar Fragment in Distal Radius Fractures Treated Using the Integrated Compression Screw With a Mini-Plate.

Stabilization for displaced dorsoulnar fragments in distal radius fractures is challenging to treat with conventional volar locking plates alone. The integrated compression screw combined with a volar locking plate has been introduced as an additional tool to stabilize the dorsoulnar fragment and has been reported to work effectively. However, the compression screw is unable to stabilize a comminuted dorsal ulnar fragment; therefore, it is necessary to consider using an additional dorsal plate.

Double-blind, placebo-controlled, multicenter trial of a vasopressin V2-receptor antagonist in patients with schizophrenia and hyponatremia.

Objectives: Hyponatremia (serum sodium [Na+] concentration <136 mmol/L) is a prevalent and potentially life-threatening medical comorbidity for schizophrenic patients. No definitive pharmacological treatments have been established. Tolvaptan (OPC-41061), an oral non-peptide V2-receptor antagonist, was recently shown to correct hyponatremia in a diverse population of 448 hyponatremic patients.

Radiologically guided placement of pull-type gastrostomy tubes.

Purpose: To evaluate percutaneous placement of pull-type gastrostomy tubes that has traditionally necessitated endoscopic guidance.

Materials And Methods: From September 1995 through March 1997, 63 pull-type gastrostomy tubes were placed in 64 patients. Retrograde catheterization of the esophagus was performed through the stomach.
