Inhalation of foreign bodies in children. Report of 500 cases.
Inhalation of foreign bodies is a major cause of accidental death during childhood. Aspiration of foreign bodies is common in children aged 1 to 3 years, especially in boys. A past history of foreign body aspiration is itself an indication for bronchoscopic examination of the airways, because some children with aspirated foreign bodies are without symptoms and chest x-ray films may not show abnormalities. ⋯ We routinely use prednisolone, 1 to 2 mg. per kilogram, and nebulization just after bronchoscopic examination of the airways. This medication greatly diminishes the rate of postbronchoscopic complications such as laryngeal edema, which require tracheostomy. In our series of 500 case, the incidence of postbronchoscopic tracheostomy is 1.4 per cent and the total mortality rate is 1.8 per cent.

Comparative StudyLong-term survival after tricuspid valve replacement. Results with seven different prostheses.
The experience with tricuspid valve replacement (TVR) with seven different prostheses, alone or combined with replacement of other valves, in 73 patients (64 rheumatic and nine nonrheumatic) between 1964 and March, 1975, at the University of Alberta Hospital has been reviewed. Early and late mortality rates in rheumatic patients were 41 and 23 percent, respectively (36 percent being alive after a mean of 5.6 years), compared to 33 and 11 percent, respectively, in the nonrheumatic patients (56 percent being alive after a mean of 2 years). Of all survivors, 88 percent were functionally improved. ⋯ Among the nonrheumatic patients, two with the Cutter-Smeloff, two with the Beall-Surgitool, and one with the Lillehei-Kaster were alive after 14, 37, and 15 months, respectively. Among all survivors of TVR, late thrombus and pannus developed on both ball and disc prostheses (Starr-Edwards, two; Cutter-Smeloff, one; Lillehei-Kaster, one). These findings suggest that TVR should be performed earlier in rheumatic patients to reduce the operative mortality rate and that the Lillehei-Kaster prosthesis is probably most suitable for TVR.

Case ReportsPrimary liposarcoma of the mediastinum. Report of a case and review of the literature.
Primary liposarcomas of the mediastinum are very rare tumors. We record herein the fiftieth documented case, and the sixth in which there was evidence of superior vena caval obstruction. All previously reported cases have been studied; their salient clinical and pathological features have been tabulated. ⋯ Radiotherapy or chemotherapy or both are ineffective theraputic modalities. The treatment of choice is surgical in all cases. Such an approach serves to establish a tissue diagnosis, to relieve the patient's symptoms, and may at times result in a cure.
