The therapeutic results of operatively and conservatively treated patients with lumbar disc syndromes were reviewed in a retrospective study. The patients were treated during a 10-years period (1976-1985). A total of 330 patients with lumbar disc prolapses were treated in the hospital during this period 44% were treated surgically. ⋯ There were no definite advantages found for either of the two methods of treatment. The necessity for a specialized follow-up treatment of patients with sciatica due to herniated lumbar discs is discussed, and differentiated selection for operative therapy is given. Here the treatment of pain should be considered most important.

Neuroadenolysis of the pituitary (NALP) is an efficient measure for treatment of severe pain in patients with bony metastases. It is especially recommended for primary carcinomas of the breast or prostate. The procedure, transsphenoidal puncture of the pituitary under radiographic control and instillation of up to 2 ml 95% alcohol, is simple. ⋯ The following results are significant (P<0.05): (1) LH: poststimulation values are extremely suppressed; (2) FSH: basal values decrease; (3) ACTH: basal values decrease after the 6th day. The antalgic effect of NALP is independent of its hormonal consequences. NALP produces hormonal suppressions of various degrees, and is not a "chemical hypophysectomy".

Effects of various catecholamines on high-energy phosphates of rat liver and brain during hemorrhagic shock measured by 31P-NMR spectroscopy.
The effects of dopamine, epinephrine and norepinephrine on energy metabolism as well as intracellular pH in rat liver and brain during hemorrhagic shock were examined by in vivo 31P-NMR spectroscopy. The hemorrhagic shock was induced by arterial bleeding to a mean arterial pressure (MAP) of 30-40 mmHg. Upon the induction of hemorrhagic shock, there was a dramatic fall in adenosine triphosphate (ATP) and a rise in inorganic phosphate (Pi) in the liver. ⋯ After infusion of the above catechollamines following 10 min of hemorrhagic shock, MAP increased to 90-100% of its control value. Only dopamine improved hepatic energy metabolism, whereas brain energy metabolism was not affected by any of them. This suggests that dopamine protects liver function during hemorrhagic shock without affecting brain energy metabolism.

In the past the view has often been expressed that children are less sensitive to pain than adults as a result of the assumption that their nervous system is not as well developed. According to this theory, newborns were not supposed to feel pain at all, and for this reason minor surgery was often performed with inadequate anesthesia. Evidence in the more recent literature and the regular choice of "pain in children" as a topic for congresses exemplify the more and more widespread belief that children of all ages can feel pain and, relative to their developmental stage, suffer accordingly. ⋯ As cognition develops further, the patient's own concept of health and sickness changes, as does the ability to express feelings of pain. In the pathogenesis of pain in children, the dominant types are nociceptor pain (e.g., as a result of trauma or infection) and pain resulting from malfunction (e.g., physical malposition, migraine), whereas nervous pain occurs less frequently. Pediatricians should pay particular attention to the treatment of acute and chronic pain in children.

The gate control theory resulted in intensified consideration and investigation of psychological factors in the pathogenesis and continuation of chronic pain. This had led to an increasing interest in the efficacy of psychotherapy for such patients. The different forms of psychotherapy (hypnosis, relaxation, behavior therapy, psychodynamically oriented therapy) currently most often applied are reviewed with notes on the methods and the efficacy recorded for each. ⋯ The small numbers of patients evaluated in most of the studies suggest that the population investigated may well not be representative, especially if the difficulty of motivating chronic pain patients to present for psychotherapy is taken into account. In addition, a diagnostic classification of the population investigated is lacking. Conclusions are drawn for the planning of future therapy studies.
