Diagnostic quality versus patient exposure with five panoramic screen-film combinations

Five film-screen combinations were used to make five density-matched panoramic radiographs of a tissue-equivalent phantom skull using the Midwest/Morita Panoral x-ray machine. The radiographs were evaluated as to their diagnostic quality by twenty dental radiologists. The results demonstrate that proper screen-film selection can significantly reduce patient exposure without compromising diagnostic quality.     

Timing of Return to Dialysis in Patients with Failing Kidney Transplants

In the last decade, the number of patients starting dialysis after a failed kidney transplant has increased substantially. These patients appear to be different from their transplant‐naïve counterparts, and so may be the timing of dialysis therapy initiation. An increasing number of studies suggest that in transplant‐naïve patients, later dialysis initiation is associated with better outcomes. Very few data are available on timing of dialysis reinitiation in failed transplant recipients, and they suggest that an earlier return to dialysis therapy tended to be associated with worse survival, especially among healthier and younger patients and women. Failed transplant patients may also have unique issues such as continuation of immunosuppression versus withdrawal or the need for remnant allograft nephrectomy with regard to dialysis reinitiation. These patients may have a different predialysis preparation work‐up, worse blood pressure control, higher or lower serum phosphorus levels, lower serum bicarbonate concentration, and worse anemia management. The choice of dialysis modality may also represent an important question for these patients, even though there appears to be no difference in mortality between patients starting peritoneal versus hemodialysis. Finally, failed transplant patients returning to dialysis appear to have a higher mortality rate compared with transplant‐naïve incident dialysis patients, especially in the first several months of dialysis therapy. In this review, we will summarize the available data related to the timing of dialysis initiation and outcomes in failed kidney transplant patients after returning to dialysis.     

Noncirrhotic portal hypertension in Felty's syndrome.

A case of Felty's syndrome with nodular regenerative hyperplasia of the liver, presinusoidal portal hypertension, and bleeding esophageal varices is reported. Increased splenic blood flow may be a contributing factor to the development of the regenerative nodules. The portal hypertension is postulated to be a result of intrahepatic vascular compression.     

Childhood Soccer Injuries Treated in U.S. Emergency Departments

Objectives: Soccer, an increasingly popular sport among children in the United States, is a common precipitant to injury‐related emergency department (ED) visits. The authors estimated the number of children treated in EDs for soccer‐related injuries and described the nature of these injuries. Methods: Data from the 2000 National Electronic Injury Surveillance System All Injury Program were used to estimate the overall number and rate of soccer injuries in children, calculate injury rates per 1,000 children, and describe the body regions affected and types of injuries. Results were stratified by five‐year age groups (5–9 years, 10–14 years, and 15–19 years). Results: Approximately 144,600 children sustained soccer‐related injuries in 2000 for a rate of 2.36 injuries per 1,000 children. Injury rates increased with age (0.8, 5–9 year olds; 3.1, 10–14 year olds; 3.2, 15–19 year olds). Common types of injuries were strains/sprains (36.7%), fractures (23.0%), and contusions (20.9%). Fractures decreased with age; sprains/strains increased with age. Commonly injured body regions varied by age. Wrist and finger injuries were most common (12.7% and 12.4%, respectively) in the youngest group; in the 10–14‐year‐old group, ankle and wrist injuries were most common (15.7% and 13.6%, respectively). In the oldest age group, ankle injuries were most common (21.9%), followed by knee injuries (17.6%). Conclusions: Substantial numbers of children were treated in EDs for soccer‐related injuries. Injury types and affected body regions varied by age. Injury prevention efforts to reduce soccer‐related injuries may need to be age specific.
