External heart compression during cardiopulmonary resuscitation is an usual method. As an alternative to the arm-hand method the leg-heel method is proposed. Both methods were tested with a group of laymen and paramedical personnel at the Recording Resusci-Anne manequin. Criteria of evaluation were frequency, point, intensity and direction of heart pressure. 64 per cent of all test persons found the method of heel-compression to be of no value of the basis of personal experience. They showed early fatigue and complained of leg pain. The incidence of failure for both methods was comparable. Frequency and intensity of pressure showed no differences. The most important disadvantage appeared to be the lack of discharge of the sternum at the end of the phase of compression. Experience has shown that difficulties may arise from teaching several methods. Therefore the teaching of laymen should be restricted to one method only, usable universally. The restrictions of the leg-heel method are listed.

In the ergonomic assessment of work in 14 large laundries, it is primarily constrained posture due to working conditions and uniform overstrain that are highlighted objectively. Accordingly common are complaints about back problems, leg pain, severe fatigue, headache and nervousness (42-70%). The added work difficulties most objected to include heat (rate of mention in flatwork operations 80%), dust, dirt, odors (in sorting operations 75%), constant standing and walking (in several areas of work 70-80%), too great exertion of the arms (in sorting and folding operations 50-67%), and noise (depending on area of work 33-73%). On the basis of these results, attempts at resolving these problems to improve the organization of work in large laundries were developed. These include for example, an adequate capacity to adjust the working surfaces, suitable seats and aids for standing, installation of platforms, and further measures to reduce overstrain.

According to the present study, in addition to the high accident rate, work in the building trade is characterized by intense muscle strain and constrained physical posture. In bricklaying, for example, a worker moves by hand up to seven tons of stone per shift. Consequently, various health complaints occur far more frequently in this occupation than in the other occupational groups, for instance, back complaints (71%), severe fatigue (58%), pain in the arms and hands (42%), headache (40%) and leg pain (34%). The most complained of factors include effects of the weather (74%), draft (50%), noise (55%), air pollution via dust (53%), skin contact with dirt and harmful substances (47%), moving heavy objects by hand (53%), adverse posture during work (47%), and a high risk of accidents (47%). Besides technical and organizational measures, the prevention of health impairments in employees in the building trade should be promoted by purposive care by works services of occupational medicine.

Progressive diaphyseal dysplasia is characterized clinically by crippling leg pain, fatigue, headache, poor appetite, muscle weakness, and waddling gait. Twelve affected patients, aged 2 years 4 months to 40 years, were treated with intermittent courses of low doses of prednisone given in a single dose on alternate mornings for periods ranging from 6 months to 10 years. The average initial dose of prednisone was 0.6 mg/kg/d, and average maintenance dose was 0.3 mg/kg/d. Relief of all crippling symptoms was achieved in all patients. No untoward serious side effects have been observed, and the growth of children was not slowed. However, corticosteroid therapy should be restricted to patients suffering from crippling pain. The mechanism through which steroids act remains undefined.

In a comparative randomized double-blind study, 73 patients underwent myelography using iopamidol (36 patients) or metrizamide (37 patients) as contrast medium. The overall diagnostic adequacy of iopamidol myelography was found to be comparable to that of metrizamide myelography. The incidence of examinations graded as superior (64%) or adequate (36%) with iopamidol was equivalent to that with metrizamide (57% superior, 43% adequate). Adverse reactions after iopamidol myelography were fewer, less severe, and generally of shorter duration than those associated with metrizamide. In the iopamidol group, adverse reactions occurred in nine (25%) patients, all of whom experienced mild or moderate headache, one with nausea, vomiting, and fatigue. In the metrizamide group, adverse reactions occurred in 17 (46%) patients, all of whom experienced mild or moderate headache, six with nausea and vomiting and four with back and leg pain. Of nine individuals who underwent myelography using 300 mg 1/ml metrizamide injected via lateral C1-C2 puncture, three experienced a toxic encephalopathy with confusion, dysphasia, headache, nausea, and vomiting, and a fourth individual suffered severe nausea, vomiting, fever, and irregular pulse. Encephalopathy was not observed in any of the 11 patients in whom myelography was performed via lateral C1-C2 puncture with a similar concentration of iopamidol. No seizures were encountered, and no clinically significant changes in laboratory studies were observed with either contrast medium.

A series of 29 patients, all engaged in sports activity on a regular basis, suffering from recurrent compartmental syndrome, is reported. The syndrome is not restricted only to long distance runners but to athletes involved in a variety of sports activities (soccer, volleyball, cycle racing, gymnastics, judo, physical education, and long distance running). Although most patients presented activity-related leg pain, some patients mainly complained of ankle weakness and recurrent ankle distortions at fatigue. The wick catheter technique proved to be most useful to determine which compartments were involved. The severity of clinical symptoms correlated highly with the anomalies of the tissue pressure measurements. The predominance of deep posterior compartment and multiple compartment involvement are in contrast with most previous reports. Conservative treatment was unsuccessful in every patient, whereas surgical decompression of the involved compartments yielded favorable results in those cases where all the involved compartments were released.

A prospective study of patients with neurogenic claudication and lumbar spinal stenosis was undertaken to determine whether measurement of exercise tolerance on the treadmill would be useful in defining baseline functional status and response to surgical treatment. Twenty patients with an average age of 73 years, all of whom had intractable neurogenic claudication and radiographically confirmed severe lumbar spinal stenosis, were studied. Lumbar decompressive laminectomy was performed in all patients. Preoperatively and 2 months postoperatively, quantitative assessment of ambulation was conducted on a treadmill at 0 degree ramp incline at two different speeds: 1.2 mph and the patient's preferred walking speed. The following information was recorded: time to first symptoms, time to severe symptoms, and nature of symptoms (leg pain, back pain, or generalized fatigue). The examination was stopped after 15 minutes or at the onset of severe symptoms. In the preoperative 1.2-mph trial, the mean time to first symptoms was 2.68 minutes (median 1.31) and the mean time to severe symptoms was 5.47 minutes (median 3.42). In the postoperative trial at the same speed, 13 patients (65%) were able to walk symptom free for 15 minutes. The mean time to first symptoms was 11.12 minutes (median 15) and the mean time to severe symptoms was 11.81 minutes (median 15). Similar findings were recorded in the preferred walking-speed trials. There were no complications from the treadmill testing procedure. These findings indicate that exercise stress testing on a treadmill is a safe, easily administered, and quantifiable means of assessing baseline functional status and outcome following laminectomy in patients with symptomatic lumbar spinal stenosis.

The effect of alpha 1-adrenoceptor blockade (doxazosin, 4 mg daily) on maximal VO2 and physical endurance capacity in 16 mildly hypertensive, athletic men was investigated in a randomized, placebo-controlled, double-blind, two-period of 4 weeks, cross-over study. The maximal workload obtained during graded bicycle ergometer exercise and the corresponding maximal VO2 were reduced by 16 +/- 3 W (mean +/- SE), (P = .00003) and 3 +/- 1 mL/(kg.min) (P = .0004), respectively, on doxazosin compared with placebo. The running time on a 5000 m track increased by 43 +/- 12 sec on doxazosin (P = .04). Heart rate was unchanged during the running session. Systolic blood pressure was reduced by 9 +/- 4.1 mm Hg (P = .04) immediately after finishing 5000 m. Six subjects reported side effects from doxazosin (headache, fatigue, and leg pain). Thus, antihypertensive treatment with alpha 1-selective adrenoceptor blockade moderately, but significantly, reduces maximal O2 consumption and high intensity physical endurance capacity in mildly hypertensive athletic men. Significantly reduced systolic blood pressure and unchanged heart rate immediately after running, combined with unchanged heart rate during the race may, however, suggest a safer exercise performance.

A 56-year old man was admitted to the hospital with malaise, weakness, and fatigue. He was short of breath and had bilateral foot edema. Even though he had been very active a month earlier, he could no longer climb stairs. For the last two weeks, he had had a cough producing green sputum, a "tight feeling" in his chest, polyuria, and polydipsia. He had not had radiating chest pain, palpitations, leg pain or erythema, hemoptysis, diaphoresis, flushing, fever, chills, nausea, vomiting, diarrhea, or a loud snore.

This study investigated the effectiveness of several possible exercises for performance during standing work in order to prevent lower leg swelling and relieve subjective complaints. Volume changes in the lower leg were measured using bioelectrical impedance plethysmography in 13 healthy male subjects aged 23-36 years. Subjective complaints of leg pain, leg dullness and whole body fatigue were also recorded. Measurements were performed at two-minute intervals during a one-hour period of standing with insertions of one-minute of exercise every 10 min. The exercises were knee-bending, foot-stepping, walking, and heel-raising. The change rates of impedance over one hour were 2.2%, 4.0%, 4.6%, and 6.3%, respectively, indicating that leg volume was increased under all exercise conditions. Among exercises, the swell-preventing effect of knee-bending was strongest, and that of heel-raising was weakest. Heel-raising also yielded the highest number of subjective complaints. Knee-bending, which uses the thigh and calf muscles simultaneously, was considered the most effective for suppressing lower-leg swelling and minimizing subjective complaints.
