The aim of this study was to define the outcome and complications following open reduction and internal fixed-angle plating of distal radius fractures for patients on chronic immunosuppression medications. A retrospective study identified 11 patients with distal radius fractures that had been on chronic immunosuppressive medication. The mean patient age was 59.9 years (40–82 years). According to the Orthopedic Trauma Association classification, there was one 23A3, one 23B3, and nine 23C type fractures. There were two open fractures. All patients received preoperative antibiotics and underwent reduction and fixation with a volar, fixed-angle plate. Postoperative measurements included postoperative and final radiographic indices, wrist flexion and extension, forearm rotation, and grip strength. Clinical follow-up averaged 13 months, and radiographic follow-up averaged 14.9 months. Statistical analysis was performed comparing means of various parameters with a two-sided t test with an alpha value ≤0.05. All fractures healed, and there were no infections. The final mean ulnar variance, volar tilt, and radial inclination were –0.1 mm (ulnar negative; –2.0 to +2.5 mm), 13° (5–23°), and 21° (15–27°), respectively. The mean articular gap or step was 0.4 mm. There was a small but significant decrease between the final and postoperative mean ulnar variance ( p=0.03). Mean wrist flexion was 47°, extension 47°, pronation 77°, and supination was 76°. Grip strength averaged 16.3 kg versus 25.1 kg for the opposite extremity. The one major complication included a postoperative carpal tunnel syndrome. Fixed-angle volar plate fixation for distal radius fractures in patients with chronic immunosuppression was associated with union (with acceptable radiographic alignment), no wound-healing problems or infections, and with functional wrist and forearm motion and grip strength.

The objective of this retrospective cohort study was to describe the incidence of paroxysmal atrial fibrillation and to determine its risk factors and effect on outcome in critically ill patients with sepsis. The study included 81 patients with sepsis admitted to an intensive care unit. In all, 25 patients (31%) developed paroxysmal atrial fibrillation. Advanced age, history of paroxysmal atrial fibrillation, higher severity of illness at intensive care unit admission, and lower left ventricular ejection fraction were risk factors for paroxysmal atrial fibrillation. Multiple logistic regression analysis showed that paroxysmal atrial fibrillation was independently associated with 28-day mortality (odds ratio = 3.284; 95% confidence interval, 1.126-9.574). The incidence of paroxysmal atrial fibrillation is high in critically ill patients with sepsis. It occurs more frequently in patients with advanced age, history of paroxysmal atrial fibrillation, high severity of illness, and lower left ventricular ejection fraction and is associated with increased mortality.
