Computerised infrared thermography and isotopic bone scanning in tennis elbow.

Thirty five cases of tennis elbow (17 unilateral, nine bilateral) were studied with infrared thermography and isotopic bone scanning. A hot focus was visualised in 16 of 17 cases of unilateral tennis elbow (94%) and in all nine cases of bilateral tennis elbow (100%) on infrared thermography, and abnormal increased epicondylar activity seen in 12 of 17 (71%) and eight of 18 (44%) cases respectively with isotopic bone scanning. Unilateral visual cooling (somatosympathetic responses) occurred in seven of 13 cases of unilateral tennis elbow (54%) with infrared thermography, and reduced perfusion in seven of 12 (58%) of similar cases with blood pool isotopic bone scanning. Computerised temperature assessments showed statistically significant side to side temperature differences when 17 active tennis elbows were compared with the opposite normal elbows for spot temperatures, proximal and distal forearm gradients. Similar temperature assessments in 18 bilateral tennis elbows compared with 17 normal elbows showed significant temperature differences for elbow spot temperatures and distal forearm gradients, but not for proximal gradients.

Abdominal wall actinomycosis associated with use of an intrauterine device: a case report.

The association between pelvic actinomycosis and the use of intrauterine devices is well established. However, abdominal wall actinomycosis without clinical involvement of the pelvic organs has been reported only once in the literature. The authors present a second case, which occurred in a 24-year-old woman who was using a copper 7 intrauterine device.

The relationship of locus of control, age, and sex to life satisfaction and death anxiety in older persons.

The present study examined Rotter's Internal-External (I-E) locus of control (LOC) concept in relation to life satisfaction and death anxiety in an aged population. Age and sex of the individual were also considered. In the case of life satisfaction, a strong sex and a strong locus of control effect were found. For death anxiety, again a strong sex effect was found, but there was also a significant interaction between locus of control and age. The article suggests the need for a life span developmental perspective in LOC research. Studies which explore the influence of life experiences, situational and environmental variables, and their effect on control orientation are also needed.

Hemodynamic properties of bucindolol, a beta-adrenoreceptor blocking drug with vasodilator activity.

Bucindolol is a new nonselective beta-adrenergic blocking agent with direct vasodilator, partial agonist and alpha-adrenergic blocking properties. Its hemodynamic effects were evaluated in 13 healthy young men. In an open study, the effects of increasing single oral doses (50 to 200 mg) were examined. Two hours after each dose there was little effect at rest, but the responses of heart rate and systolic blood pressure to cycle exercise (50 to 150 W) were significantly reduced. There was no greater effect with larger doses. The second phase was a 3-way double-blind study comparing the effects of placebo with 50 and 200 mg of bucindolol. Left ventricular (LV) ejection phase indexes derived from digitized M-mode echocardiograms (% fractional shortening, mean and peak velocity of circumferential fiber shortening, stroke volume) increased more than 10% 2 and 4 hours after bucindolol was administered, whereas systemic vascular resistance and the ratio preejection period/LV ejection time decreased to the same extent. Although there was little effect on measurements at rest, the response to cycle exercise of heart rate and systolic blood pressure were significantly attenuated. These results show that the effects of bucindolol on LV systolic function are related at least in part to reduction of afterload, but do not indicate whether the drug has an additional direct inotropic effect.

Peripartum cardiomyopathy: echocardiographic features in five cases.

Five cases of peripartum cardiomyopathy are presented. All patients were aged less than 35 years, and four were multiparous. Two cases followed twin deliveries. Pulmonary embolism was diagnosed in four patients. Electrocardiograms showed left ventricular hypertrophy or left bundle branch block. On echocardiography, left ventricular minor axis dimensions were increased (diastolic, 67 +/- 7 mm; systolic, 59 +/- 7 mm) and mean fractional shortening was reduced (13% +/- 5%). All patients had hypokinesis or akinesis of the left ventricular segments and two had right ventricular dilatation. Gallium scanning performed in three patients was negative. Viral serologic testing was negative in all cases. All patients died within 5 years, three within 5 months. Survival duration was closely correlated with left ventricular fractional shortening. Autopsy in three patients confirmed the diagnosis of a dilated cardiomyopathy.

Comparison of flexible sigmoidoscopy with other diagnostic techniques in the diagnosis of rectocolon neoplasia.

Flexible sigmoidoscopy was compared to rigid sigmoidoscopy in the detection of colorectal neoplasia in a select group of patients. A distance of 30 cm or greater was obtained by flexible sigmoidoscopy in 94% of patients and a distance of 50 cm or greater in 46% of patients. A significant number of cancers and adenomas detected by flexible sigmoidoscopy were not detected by rigid sigmoidoscopy. Flexible sigmoidoscopy was tolerated better than rigid sigmoidoscopy but required twice the time. Flexible sigmoidoscopy could be combined with air-contrast barium enema the same day with the one preparation and did not interfere with the x-ray examination. All cancers and a significant number of adenomas detected subsequently on colonoscopy were detected by the combination of flexible sigmoidoscopy and air-contrast barium enema. Although the combination of flexible sigmoidoscopy and air-contrast barium enema is not adequate for thorough diagnostic evaluation of patients with a positive screening test, it may be of value in other select clinical situations. Flexible sigmoidoscopy has the potential for higher yield and better patient tolerance as compared to rigid sigmoidoscopy. This warrants further evaluation.

Carcinoembryonic antigen in colonic lavage.

Colonoscopic lavage was performed for assay of carcinoembryonic antigen (CEA) concentration in patients with small and large colonic adenomas, in patients with adenocarcinoma of the colon, and in normal controls. CEA concentration was considerably higher in colonoscopic lavage as compared to plasma. CEA concentration in normal controls and in patients with colonic adenomas less than 1 cm in size were not significantly different. CEA concentrations in patients with colonic adenomas greater than 1 cm in size and in patients with adenocarcinoma of the colon were significantly higher than those observed in patients with small adenomas and in the normal controls. In all except 2 patients, plasma CEA concentrations were normal. Assay of CEA concentrations in colonic lavage may have potential application in the further assessment of the mucosa at risk for colon adenomas and for colon cancer. It does not appear to be accurate enough for diagnosis of colon cancer in individual patients.

Ultrasound for detecting osteomyelitis in turkeys.

One thousand turkey legs were examined for osteomyelitis (OM) by ultrasonographic, pathologic, and bacteriologic examinations. OM lesions were recognized as hyperechoic (brighter white) disruptions in cortical bone in the growth plate region by ultrasound examination OM was confirmed histologically in 139 of 1000 legs. OM was detected by ultrasound in 109 of 139 OM-positive legs for a sensitivity rate of 78%. OM was not detected by ultrasound in 713 of the 861 OM-negative legs for a specificity rate of 83%. Ultrasonography was superior to current use of green liver discoloration for detection of tibial OM in turkeys at processing. The economic benefit to the turkey industry from the approval and application of this procedure could be considerable.
