[Q]: Abstract: Clinical and morphologic features of 89 cases of childhood yolk sac tumor (YS) and embryonal carcinoma (EC) (29 associated with teratomas) submitted to the Rare Tumor Registry of the Southwest Oncology Group (1971-1979) or the Pediatric Oncology Group (1980-1984) between 1971 and 1984 were reviewed and submitted to statistical analysis. This review showed an improved survival for each 5-year period regardless of tumor site, no statistically significant difference between "pure" tumors and those mixed with other teratomatous components, no statistically significant difference between YS and EC in children, a better than reported prognosis for sacrococcygeal tumors occurring after the neonatal period, a particularly poor prognosis for neonatal "benign" sacrococcygeal teratomas resected without coccygectomy when they recur as YS, excellent survival for all testicular tumors regardless of age or the presence of EC, and the occurrence of mediastinal tumors in females.

[Q]: Abstract: We examined the effects of a paramagnetic contrast agent, gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) on magnetic resonance images of acute myocardial infarction with and without reperfusion. Twenty-two dogs underwent occlusion of the left anterior descending coronary artery (LAD). In 10 dogs (group I) the LAD remained occluded for 3 hr and in the other 12 (group II) for 2 hr followed by 1 hr of reperfusion. Gd-DTPA (0.34 mM/kg) was administered to five dogs in group I at 2 hr and 5 min after occlusion and to seven dogs in group II 5 min after reperfusion. At 3 hr after ligation, the hearts were excised and imaged with spin echo and inversion recovery pulse sequences on a 0.35 Tesla magnetic resonance imager. Reperfused hearts given Gd-DTPA demonstrated a significant increase in contrast between normal and reperfused myocardium as compared with nonreperfused hearts and reperfused hearts not given Gd-DTPA. This enhancement was particularly prominent in the inversion recovery images. Studies performed in vivo in two additional dogs demonstrated similar enhancement with reperfusion with Gd-DTPA in gated spin echo images. Contrast-enhanced magnetic resonance imaging allows the detection of reperfusion early in the course of acute infarction.

[Q]: Abstract: To investigate the effect of interictal epileptiform discharges (IEDs) on plasma prolactin (PRL) level, we studied 18 epileptic patients with complex partial seizures (CPS) who did not experience clinical or subclinical ictal events during all-night monitoring with polygraphic recording and video imaging. The density of IEDs peaked during non-REM stages and was significantly reduced during REM stage. Mean plasma PRL concentrations in epileptic patients, when sampled at 30-min intervals, showed a moderate but significant elevation during non-REM (p less than 0.001) and awake stages (p less than 0.005), but not during REM stage, when compared with 10 nonepileptic control subjects studied in a similar fashion. The data obtained in this physiologically controlled environment indicate that the cumulative effect of IEDs may modify PRL regulatory mechanisms, resulting in a modest elevation of plasma concentrations independent of ictal discharges.
