[Comparison of the oxygen deficit and ischemia pain threshold in patients with silent and symptomatic myocardial exercise-induced ischemia].

In 39 patients with angiographically documented coronary artery disease and silent or symptomatic myocardial ischemia under exertion it was investigated if there is a difference in forearm skeletal muscle ischemia and ischemic pain threshold. The degree of myocardial ischemia was determined by plethysmographically measured reactive hyperemia. In 12 asymptomatic and eight symptomatic patients maximal reactive hyperemia was induced by ischemic work in the forearm skeletal muscle. After termination of ischemia there was a significantly higher reactive hyperemia at 20, 90, and 180 s in the asymptomatic patients. Furthermore, nine asymptomatic and 10 symptomatic patients underwent symptom-limited ischemic work until weakness or pain developed. Under these conditions reactive hyperemia as a parameter of oxygen deficiency was higher in the asymptomatic patients. The difference was not statistically significant. There was, however, a significantly higher incidence of ischemic pain in the symptomatic patients. It can be concluded that patients with asymptomatic myocardial ischemia tolerate a higher oxygen deficit in the working forearm and have a higher pain threshold than patients with symptomatic ischemia.

Effects of adaptive seating devices on the eating and drinking of children with multiple handicaps.

The purpose of this study was to explore the effects of adaptive seating on oral-motor functioning as it relates to eating and drinking in 11 children with multiple handicaps between the ages of 1 and 4 years. An assessment instrument with a behavioral base was used for the seven direct observations of each child's motor behavior. During the first and last visit the parent or guardian filled out a pre- and post-equipment questionnaire. Evaluations were conducted every 6 weeks beginning 3 months before and ending 6 months after the receipt of the seating devices. An analysis of variance was used to analyze rating scale score data. A nonparametric sign test was used for the analysis of yes/no data. Other data were analyzed for frequencies and central tendencies. Sitting posture and head alignment during eating and drinking improved significantly. A significant increase in the frequency with which liquid and food was retained in the mouth was noted. A significant number of children progressed from bottle to cup drinking and from eating blended to chopped or cut-up food. The present research extends beyond case study and retrospective study reports to support the efficacy of the use of adaptive seating devices by children with multiple handicaps.

[Computed tomography following facial surgery].

During the first four to six weeks after surgery, a reaction in the paranasal sinuses can be demonstrated by CT. Similar opacifications appearing later were due to tumor recurrency. Tumor recurrency leads to an increase of soft tissue structures, disappearance of vascular structures, and an increase of bone destruction. The bone destruction can show characteristic fragmentation, with the fragments at a certain distance from each other. If the recurrence is known, CT shows the extension, similar to normal preoperative CT. Follow-up examinations improve safety of interpretation.

[Computer tomography following hypophysectomy].

The authors analyzed the computerized tomograms of 17 patients who had been operated on for tumors in the sellar region. After pituitectomy from a transnasal approach the following was observed: bone defects in the area of the posterior ethmoid cells and at the sphenoid sinus (1), partial absence of the sellar floor (4), a shadow on the ethmoid and sphenoid sinuses (2), an empty sella (1), damaged tissue in the sellar region (1) and blood in the area operated on (1). After pituitectomy from a transcranial approach, the following was seen: trepanation damage frontoparietally on the right (6), trepanation damage frontoparietally on the left (3), brain substance damage below the trepanation (4), and an empty sella (5). The following had occurred as a result of the primary disorder: expansion of the sella (twice), a displacement of the middle structures (twice), bone arrosion in the sella area (once) and a tumor picture in the pituitary area (in eight cases). Air may be encountered postoperatively in the various regions within the calvaria. For the first two weeks at least, its existence is not indicative of the presence of a liquor fistula.
