Fifty five patients, with an history of chronic low-back pain, with or without leg pain, took part to the study. The fibrinolytic activity of these patients was studied after a 10 min occlusion test, aimed to enhance the fibrinolytic system. The presence of arachnoiditis was assessed by direct surgical observation or by unequivocal myelography plus CT scanner. The fibrinolytic defect entity appears not to be rare in our chronic low-back pain population and to be common in patients with arachnoiditis, the prevalence of fibrinolytic defect being respectively of 45% (25/55 patients) and of 75% (18/24 patients). The importance of a venous occlusion test to increase sensitivity (rejection of false positive) in the detection of a fibrinolytic defect and the relation between this defect and arachnoiditis, are discussed.

In this study the correlation between the electromyographic examination of the external sphincter muscle and the urodynamic findings in patients with meningomyelocele was evaluated. Urodynamic testing, consisting of cystometry with bladder, urethral and abdominal pressure monitoring was performed with simultaneous electromyography of the external and sphincter muscle in 61 children, 29 boys and 32 girls, divided in groups according to age and to the level of lesion. Normal urodynamic studies were always correlated with normal external sphincter electromyography. In all patients with a high lesion and in 79% of all others detrusor hyperactivity was correlated with pathological sphincter electromyography. The clinical neurological level of the lesion was not correlated with the function of the detrusor-sphincter mechanism. In 29% of the patients examined with needle electromyography detrusor-sphincter dyssynergia was found, which is less than in most other published studies. And although dyssynergia is a risk factor for renal deterioration, the authors conclude that its effect on the ureter is less important than in subjects with normal perineal musculature, since 80% of the examined patients with meningomyelocele showed pathological sphincter electromyography. These findings thus show a significant correlation between electromyography of the external sphincter muscle and the urodynamic findings in meningomyelocele patients, and clearly demonstrate the importance of urodynamic testing with simultaneous external sphincter electromyography, in order to improve both diagnostic accuracy and reliability of follow-up and treatment.

As people come frequently into contact with electrical power sources, electrical injuries to peripheral nerves are commonly seen. The authors first review the parameters determining the severity and distribution of electrical injury to nerve tissue. These include tissue resistance, tissue susceptibility, current pathway, type of current, current density, duration and size of electrical contact. Subsequently, the pathophysiology of electrical injuries to nerve tissue is reviewed. Such injuries can be the result of thermal damage, vascular impairment, histological or electrophysiological changes in peripheral nerves, or direct mechanical trauma. Each of these types of injuries causes, specific lesions. As these lesions, especially delayed peripheral neurologic injury, can cause medico-legal problems, it is important to emphasize that electroneuromyography must be performed as early as possible.

Condensing osteitis of the clavicle, better defined as aseptic enlarging osteosclerosis of the clavicle, is a rare and benign idiopathic lesion. It is probably of degenerative or mechanical origin, and is most commonly seen in middle-aged women as a tender swelling over the medial one-third of the clavicle. Although the clinical features may be confusing and nonspecific, the typical radiographic and histopathological findings will mostly lead to a correct diagnosis of this disorder. The differential diagnosis is quite extensive. Most difficult to differentiate are: avascular necrosis of the medial clavicular epiphysis, sternoclavicular orsteoarthritis, low-grade chronic osteomyelitis, sternocostoclavicular hyperostosis and Tietze's syndrome. The authors recommend a thorough physical examination and technical tests, not only in subjects with pain of the clavicle but also in those with shoulder pain only, especially in women who are in their fourth decade. Treatment with analgesic and anti-inflammatory medications may be variably effective. In refractory cases excisions of the medial one-third of the clavicle may be indicated to offer better relief of symptoms as well as to exclude malignancy.

In this paper the authors discuss the clinical problem of lumbar hypermobility. The therapeutical possibilities are resumed briefly. The philosophy of medical training therapy ("Heilgymnastik") is described. More extensive the extra-advantages of hydrotherapy (methodical back-stroke swimming) are searched for in a theoretical deductive way. The authors found that: 1. swimming is a low-impact sport so far as the articulations are concerned, 2. back-stroke is done mainly in a lumbar kyphosis, 3. swimming is also an excellent cardiopulmonary training, 4. when swimming the muscles of the shoulder girdle and pelvic girdle are trained in a nearly isokinetic way (power-endurance), 5. the short transverso-spinal muscles are indirectly trained in their tonic more than phasic stretch reflex (posture function), 6. the muscles of the trunk are trained in a nearly isometric way in the appropriate angles (erect position), 7. the position of the head in the water facilitates the abdominal muscles (tonic neck reflex), 8. the cool temperature of the water generates training-enhancing stress-responses, 9. endurance-training is ideal for the postural function of the lower back muscles (especially the deeper layers near the spine) which are anatomical and physiological suited for this purpose, 10. warming-up and cooling-down procedures prepare the neuromuscular, the cardiovascular and metabolic functions before the workout-session (a cold shower afterwards acts to tonicize the skin and muscles).
