Urinary output of endogenous monoamine oxidase inhibitor and isatin during acute migraine attacks

Summary Urinary output of endogenous monoamine oxidase (MAO) inhibitory activity, was significantly raised in serial samples collected across a migraine attack compared with collections during attack-free periods and in healthy controls, which did not differ from each other. There was a highly significant correlation in output between isatin, a major fraction of the MAO inhibitory activity, and output of the MAO inhibitory activity itself. However, although there was a tendency towards increased isatin excretion during migraine attacks, it failed to reach statistical significance.     

The effects of patient, hospital, and physician characteristics on length of stay and mortality

This article compares the ability of hospital and physician characteristics to explain variations in length of stay and mortality, controlling for factors associated with severity of illness. The analysis is based on 54,571 discharges, covering 11 medical and five surgical conditions, from nonfederal general hospitals in one state during 1988. Results suggest that both hospital and physician characteristics are important predictors of both outcome measures. Contrary to previous research, the volume of patients with the same condition treated by the hospital increases both length of stay and mortality. The volume of patients with the same condition treated by the physician increases length of stay among patients with medical conditions, decreases length of stay among those with surgical conditions, and decreases mortality. One interesting finding is that the medical school attended by the physician influences the patient's length of stay. Findings are interpreted in light of research evidence on factors affecting medical outcomes and recent federal efforts to improve quality of care.     

Phase I study of epirubicin given on a weekly schedule

Epirubicin was studied in a phase I setting to find the maximum tolerated dose when given weekly for 3 of 4 weeks. Forty-one evaluable patients were treated in groups at doses increasing from 20 to 45 mg/m2. The highest dose level produced the maximum degree of myelosuppression (lowest neutrophil count, 1.9 X 10(9)/L; range, 0-3.7) recorded on Day 22. This was well-tolerated in this group of mainly pretreated patients. Nonhematologic side effects were minimal. This dose schedule allows a greater dose per unit time to be administered than other recommended schedules for epirubicin.     

Magnetic resonance in the diagnosis of aneurysmal bone cyst]

A patient of 12 suffering from aneurysmal cyst of the ischium was studied with traditional radiology, computed tomography (CT) and magnetic resonance imaging (MRI). The advantages of MRI in the study of this pathology compared to traditional radiography and CT are assessed. It was shown that the CT and MRI techniques are superior to standard X-ray examinations in anatomic definition and in evaluating the lesions's relationships with neighbouring structures and, in particular, that MRI is superior to CT in extension.     

A portable system for measuring cutaneous thresholds for warming and cooling.

Measurement of cutaneous thermal thresholds is a valuable technique for detecting small fibre neuropathy. A robust and portable microcomputer controlled system, which separately measures thresholds for warming and cooling, is described. Thresholds at three sites have been measured; the cheek, the dorsum of the hand and the sole of the foot. Regional variability and a correlation with age have been found, indicating the sensitivity of this system.     

Popliteus tendon rupture. Case report and review of the literature

A 23-year-old man sustained an isolated popliteus tendon rupture while pushing a car. The diagnosis was established with the use of arthroscopy, electromyography, and Cybex testing. After the patient failed to respond to conservative therapy, the tendon rupture was surgically repaired. The patient had an uneventful recovery and returned to his preinjury level of athletic activity. Although popliteus tendon tenosynovitis as well as injury to the popliteus in association with other ligamentous knee injuries has been described, neither an isolated popliteus tendon rupture nor an arthroscopic evaluation of a popliteus tendon rupture has been reported.     

P300 and the Risk for Alcoholism: Family History, Task Difficulty, and Gender

P300 event-related brain potentials (ERPs) were obtained from 20 pairs of male and 20 pairs of female undergraduate subjects. One member of each pair reported having a father who was alcoholic (FHP), the other reported no known alcoholic biological relative (FHN). Pair members were matched on age, height, weight, grade point average, and personal drinking history. Three auditory tasks which differed in stimulus discrimination difficulty were presented to each subject. All tasks employed 20% target and 80% standard tones with the subject required to move their index finger whenever a target stimulus was detected. No significant differences in P300 amplitude or latency were obtained between the family history subject groups, although female FHP subjects tended to have smaller P300 amplitudes than their FHN counterparts. P300 amplitude decreased with increases in the amount of self-reported alcohol consumed for FHP subjects but significantly so only for the most difficult task situation. The results suggest that the relationship between the P300 ERP and the inheritability of alcoholism is not yet clear and may be subject to modulation by task requirements, population differences, and subject sex.     

The patient''s appraisal of the cosmetic result of segmental mastectomy in benign and malignant breast disease.

Women's appraisal of the cosmetic result and their psychosocial adjustment after a standardized segmental mastectomy for benign or malignant breast disease was analyzed on the basis of a mailed questionnaire, which was satisfactorily answered by 263 (92%) of 285 women operated on consecutively. The overall result was favorable: 96.5% of the patients found the new appearance of their breast very good (30.7%), good (44.0%), or acceptable (21.8%). Women with a benign diagnosis ran a two-fold higher risk of being discontented with the new appearance of the breast than those with breast cancer. Complications of radiation therapy, preoperative concern that the breasts are important for the appearance, and anxiousness about the cosmetic result were associated with a significantly elevated risk of being less satisfied with the outcome. The main finding that it is possible to perform a locally radical operation that is highly acceptable to the woman is relevant to the surgical management of potentially malignant mammographic lesions and also to the scientific strategies for future evaluation of breast-conserving treatment modes in malignant disease.
