Donor-to-recipient transmission of bacteria as an unusual cause of mediastinitis in a heart transplant recipient.

We present a 54-year-old male heart transplant recipient who developed mediastinitis caused by Klebsiella oxytoca and Veillonella species. Culture of the donor's bronchus also grew K. oxytoca and a Veillonella species. Pulsed-field gel electrophoresis revealed that the K. oxytoca isolates had identical banding patterns. This case illustrates transmission of pathogenic bacteria via a contaminated organ.

Computerized cognitive training for severely emotionally disturbed children with ADHD.

An experiment was conducted to investigate the influence of Captain's Log (a computerized cognitive-training system) on the behaviors and performance capabilities of 4 severely emotionally disturbed children with Attention Deficit Hyperactivity Disorder (ADHD), ages 7 to 11. Behavioral scales, spectral electroencephalograms, and intelligence and performance tests were assessed pre- and posttreatment. A behavioral point system and monitoring of progress on computer tasks were used throughout treatment to evaluate ongoing improvements. There were 64 training sessions administered over a 16-week period. Outcome of treatment was determined by computer advancement, changes in behavioral points, and pre- and postmeasures. Results support the expectation that children who were most successful in the training would demonstrate the highest levels of generalization of those skills that were the focus of treatment.

The futility of the chest radiograph in the febrile infant without respiratory symptoms.

OBJECTIVE: Major pediatric textbooks advocate a chest radiograph as part of the diagnostic evaluation for a sepsis workup for febrile infants less than 3 months old. Very few studies have addressed the value of performing a chest radiograph in this situation. Two studies previously published lack the numbers to statistically justify a conclusion about the need to perform a chest radiograph in the febrile infant. METHODS: Evaluated were 197 febrile infants 3 months old or less with a history, physical examination, chest radiograph, and other laboratory studies to determine the cause of their fever. This group of infants was combined with the group of infants from two similar studies published previously in the literature using cumulative meta-analysis. The combined group resulted in 617 infants. RESULTS: The combined group of infants had 361 infants who had no clinical evidence of pulmonary disease on history or physical examination. All 361 infants had normal chest radiograph. These results gave a 95% confidence interval that the chance of a positive chest radiograph in a patient with no pulmonary symptoms would occur less than 1.02% of the time. CONCLUSIONS: The generally advocated policy of obtaining a chest radiograph as part of the sepsis workup in febrile infants should be discontinued, and chest radiographs should be obtained only in febrile infants who have clinical indications of pulmonary disease.

End result study of Stone bunionectomies.

The Stone bunionectomy is an oblique resection of the metatarsal head designed to preserve the weight-bearing margin of the metatarsal shaft. In 132 patients treated by the Stone operation, only 77 per cent were satisfied with the overall results and 19 per cent had persistent pain. In addition, only 69 per cent were considered by the authors to have had an excellent result. These results do not compare favorably with those reported for the Keller procedure. Consequently, the Stone bunionectomy is not recommended.

A.S.I.F. technique and ankle fractures.

Results of using the technique of the Association for the Study of Internal Fixation, when applied to fractures, include accurate anatomic reduction, secure fixation and allows early mobilization, resulting in rapid resumption of normal function. In a series of 71 (of 77) ankle fractures, followed for an average of 38 months, 93.5% had good or excellent clinical results.
