Peritoneal dialysis for severe methyprylon intoxication

The appropriate therapy for methyprylon (Noludar) poisoning has remained controversial, owing to a lack of reliable pharmacologic data concerning the most effective way to remove the drug after a large ingestion. We recently employed peritoneal dialysis to treat a 16-year-old girl, who had ingested 6.3 gm of methypyrlon, and were able to recover more than 80% of the unmetabolized drug in the dialysate. Clinical recovery was complete within eight hours. This appears to be a safe and effective method to remove the drug in the child or adult with a serious intoxication.

Use of high-pressure liquid chromatography for quantitative structure-activity relationship studies of sulfonamides and barbiturates

Retention volumes for a group of sulfonamides obtained on three different HPLC columns were correlated with log P, pKa, and biological activity. Depending on the chromatographic system, good correlations can be obtained with log P or with biological activity, but not necessarily both, using the same chromatographic data.

[The angiographic demonstration of a primary sarcoma of the pulmonary artery]

Following the findings of a primary sarcoma of the pulmonary artery and its angiographic demonstration, a search was made of the literature for this rare condition. Angiography is usually performed because a pulmonary embolism is suspected. It is best to inject contrast medium into the right atrium or ventricle. If an unusually large defect is demonstrated in the pulmonary artery, a primary malignant neoplasm should be considered in the differential diagnosis, particularly if the mass projects into the outflow tract of the right ventricle.
