Student and faculty perceptions of interactive learning in the radiology clerkship.

RATIONALE AND OBJECTIVES: The objective of this research is to develop and evaluate medical students' perceptions of interactive learning techniques for teaching the role of radiology in medical diagnosis to senior medical students. METHODS: Students in a 4-week radiology clerkship were given specific learning objectives and tasks that enabled them to be actively involved in radiology. Students rotated through six specialty areas in small groups. Some areas used the interactive format, whereas others used the traditional observation method. In the interactive format, clinical faculty involved student groups in examining patients, checking histories, making clinical/radiologic correlations, and discussing cases. RESULTS: Students consistently rated the interactive rotations higher (4.6 on a 5-point scale) than the observer format (3.3). The faculty and residents found the interactive format to be manageable and conducive to learning. CONCLUSION: Involving students in appropriate decision making and problem solving has proven to be a preferred way to teach radiology to medical students.

Noninvasive imaging of a retrocardiac spleen. Unusual component of paraesophageal diaphragmatic hernia.

The findings on chest roentgenograms, cardiac ultrasound, computed tomography (CT), and radionuclide liver-spleen scan are described in a 54-year-old man with a paraesophageal diaphragmatic hernia. The CT revealed the spleen as a solid mass with a notched border adjacent to the intrathoracic retrocardiac stomach. The radionuclide scan showed splenic uptake above the diaphragm. The diagnosis in this case, which, to our knowledge, is the first such reported case, was confirmed at surgery.

Interstitial pulmonary edema in children and adolescents with diabetic ketoacidosis.

The acute complications of diabetic ketoacidosis in children and adolescents are well recognized but not completely understood. Clinical studies have focused primarily on brain edema. We have investigated the prevalence and course of interstitial pulmonary edema in patients with severe diabetic ketoacidosis all of whom had uneventful clinical courses. High resolution computed tomography scans of the lungs were analyzed by determining the Hounsfield attenuation level and then converting to physical density values. All seven patients had evidence of interstitial pulmonary edema on the first scan, which was performed within 1 h of hydration and prior to receiving insulin; six of the seven patients had increased pulmonary density 6-8 h into treatment, and all had complete resolution of the interstitial changes at discharge. Our study suggests that subclinical interstitial pulmonary edema may be a frequent occurrence in children and adolescents with severe diabetic ketoacidosis and may very well be present prior to treatment. The study also supports the philosophy of cautious rehydration and the close monitoring of children and adolescents with diabetic ketoacidosis until a more complete understanding of this pathophysiologic event is achieved.
