BACKGROUND Critical pathways are healthcare management plans that specify patient goals and the sequence and timing of actions necessary to achieve these goals with optimal efficiency. More than 80% of hospitals in the United States use critical pathways for at least some of their patients. Unfortunately, critical pathway effectiveness in improving clinical… (More)
Extraosseous Ewing sarcoma — a rare clinical entity — is described and the radiographic and histologic features discussed. Histologically this type of tumor may be differentiated from other soft tissue malignancies, but the ultrastructural glycogen content of the cytoplasm makes it frequently inseparable from the conventional osseous form of Ewing sarcoma.… (More)
Hypercalcemia, often associated with certain types of adult tumors, has also been described in pediatric neoplasms. In childhood, the more common associations include lymphoma, leukemia, rhabdomyosarcoma and rarely neuroblastoma. However, recently, several infants with hypercalcemia were described having renal tumors without bone metastases. The following… (More)
During the past two years five patients with malignant primary bone tumors undergoing amputation or resection of the involved bone had preoperative computed tomography (CT) examination of the medullary cavity. The contralateral extremity was used as a control in all cases. The positive attenuation coefficient of the marrow indicated the extent of tumor… (More)
A female adolescent with hyperthyroidism was found to have an anterior mediastinal mass. Radiological investigation of this mass was consistent with thymic enlargement. Chest roentgenograms one year after treatment showed resolution of the mediastinal mass. A non-invasive investigational approach to such patients is suggested based on a review of the… (More)
Three children with ectopic ureteroceles were examined with ultrasound, intravenous urography and cystography. In all cases the ultrasound studies outlined the ectopic ureterocele within the fluid-filled bladder and in one case added additional information regarding the non-functional portion of the duplication and its ureter.
Duplications of the alimentary tract may cause extensive bleeding when ectopic gastric mucosa is present. A successful diagnosis can be made preoperatively with the use of conventional barium studies as well as sodium pertechnetate Tc 99 m scans.
The purpose of this study is to evaluate the effectiveness of buspirone in attenuating withdrawal symptoms in heroin addicts and methadone-maintained patients following cessation of heroin or methadone use. Subjects were twenty hospitalized male chronic opiate users aged 30-55 who did not present any DSM-IV Axis I disorder with the exception of opioid… (More)
Hospitals are commonly compared with each other within diagnosis-related group (DRG) categories. Administrators infer that hospitals with a higher cost per case within a DRG are less efficient than hospitals with a lower cost per case after case mix and severity adjustment. The authors assess whether hospitals that carry a heavy load of high-cost DRGs… (More)
A case of unsuspected aspiration of an oropharyngeal airway causing dysphagia is described. Visualization of this airway on plain film would be facilitated if radio-opaque material were included at manufacture.
