A case of intravenous leiomyomatosis with massive ascites is reported. This is the first such recorded case. The patient was treated with a subtotal abdominal hysterectomy and bilateral salpingo-oophorectomy. Pathological examination established a vessel wall origin. There is no evidence of recurrence up to 20 months after initial treatment.
The technique of intermittent sampling of blood during extracorporeal circulation and in vitro analysis to establish that the blood-gas status of the patient is within acceptable limits has drawbacks which may be overcome by continuous monitoring. An evaluation of an oxygen monitoring system and a comparison with a blood gas analyser have been performed. Blood of known PO2 was circulated at 15 degrees, 25 degrees and 37 degrees C in an extracorporeal system and the monitor readings and results from samples analysed on a blood gas analyser were compared with calculated partial pressures. There was no significant difference between the calculated value and the monitor readings but the blood gas analyser results were significantly lower (p less than 0.01) than the calculated values of the tonometered blood. The reasons for this difference and the potential clinical advantages of continuous monitoring are discussed.
A verbal learning test patterned after and using the same format as the Rey Auditory-Verbal Learning Test was administered to the following three groups: (1) patients with left temporal lobe epilepsy (L-TLE) as defined by EEG criteria (n = 11); (2) patients with right temporal lobe epilepsy (n = 10); and (3) normal controls (n = 11). Performance was highly similar for all three groups during the five immediate recall learning trials. The performance of the L-TLE group, averaged across three delayed recall trials (free recall, phonemic cued recall, semantic cued recall), was significantly poorer than that of the other two groups. The L-TLE group showed the worst performance on the phonemic cued recall trial, poor performance on the delayed free recall trial, and relatively intact performance on the semantic cued recall trial. Immediate and delayed free recall and phonemic and semantic cued recall for the distractor list did not discriminate groups. Word frequency, word presentation order, and concrete versus abstract words did not have different effects across groups.
