A general model of the autonomic neuroeffector junction is proposed. In this model, emphasis is placed on the muscle effector bundle with electrotonic coupling between individual cells via gap junctions (or nexuses) and en passage release of transmitter from autonomic nerve varicosities. This release results in transmission to effector cells across junctional clefts ranging from about 20 nm in the vas deferens and iris to as much as 2000 nm in some large arteries. The ultrastructural identification of different autonomic nerve types is described. Current theories on the synthesis, storage, release, and inactivation of transmitter during cholinergic, adrenergic, and purinergic transmission are summarized. Some speculations are made about the possible involvement of purinergic nerves in the innervation of vessels and mast cells in the skin, and whether this involvement results in a functional link between ATP, histamine, bradykinin, and prostaglandin in cutaneous vasodilatation. Another possibility considered as the basis for this reflex is the release of substance P from sensory (pain) nerve collaterals in the skin.

Oral naproxen in doses of 500 mg and 750 mg daily was compared with oral indomethacin, 75 mg daily, in a double-blind, completely randomized study of patients with post-operative pain after out-patients varicose vein surgery. Altogether, 120 patients were studied. In the study 750 mg naproxen proved to be equal in respect of analgesic efficacy to 75 mg indomethacin, and it was clearly superior to 1500 mg acetylsalicylic acid. Naproxen, 500 to 750 mg daily, afforded adequate post-operative analgesia in 98% of patients. The side-effects were mild. On the basis of the study, naproxen can be recommended as a pain-relieving drug after minor surgery, particularly when an antiphlogistic effect is also desirable.

This study compares a standard method of care for patients following excision and ligation of varicose veins with a new regimen which involves intermittent compression dressings. In a fully randomized between-patient prospective trial it has been found that the use of such dressings results in a significant reduction in postoperative pain and in the length of hospitalization and indicates that such dressings may improve the healing of surgical wounds.

The management of leg ulcers of venous origin begins with patient cooperation. Bed rest, leg elevation, and local care should relieve pain and initiate healing. This can be facilitated or managed on an outpatient basis by using an Unna's boot. Superficial varicosities should be ligated and stripped, and perforators identified by venography should be ligated and divided subfascially. Ulcers can then be excised and grafted. Long-term care includes chronic use of compression hose.

To test the traditional surgical view that pain in the breast is largely an expression of psychoneurosis, the Middelesex Hospital Questionnaire was given to 317 women with mastalgia and 170 controls with varicose veins. Their scores were compared with those of 173 women psychiatric outpatients tested by the designers of the questionnaire. The results were broadly similar in the mastalgia and varicose veins groups, and where there were significant differences women with varicose veins had a higher psychoneurotic score in each case. Within the mastalgia group no difference in scores was observed between patients with cyclical mastalgia and those with mastalgia due to periductal mastitis. Both groups of surgical outpatients had significantly lower scores in major traits than the psychiatric group, except for a small group of patients with breast pain who persistently failed to respond to treatment. Patients with mastalgia are therefore no more "neurotic" than those with varicose veins, and differ greatly from patients with recognized psychoneurosis. Most patients have a physiological or pathological basis for their breast pain, and they deserve an appropriate diagnostic and therapeutic approach.

Five hundred and sixty-four patients undergoing abdominal surgery, who were carefully assessed at the time of operation for evidence of venous thrombosis, have been followed up to determine the incidence of leg symptoms, varicose veins and post-thrombotic syndrome. Patients are frequently troubled by pain, swelling and phlebitis, which can persist for up to a year after operation. New varicose veins developed by 1 year in 20 per cent of patients. These occurred with increased frequency in patients who also developed a deep vein thrombosis, but they were also seen in patients who showed no clinical or isotopic evidence of thrombosis. The post-thrombotic syndrome was present in 26 patients by 3 years after the operation; half of these patients had suffered the syndrome before the definitive operation. Assessment of the long term effects of venous thrombosis must be carried out against the background of similar effects seen in patients without thrombi, and the development of the post-thrombotic syndrome may best be considered as the summation of a number of incidents, overt or occult, occurring throughout a lifetime.

Bilateral electrolytic destruction of the paramedian midbrain caudal tegmentum caused the appearance in the internal part of the hypothalamic supraoptic nucleus of neurosecretory cells with low functional activity and degenerating forms (dark-stained and pycnomorphic cells); in the posterior hypophysis the destructed gigantic terminal varicosities (Herring bodies) were revealed; the posterior hypophysis contained a subnormal amount of neurosecret; the vasopressin-antidiuretic hormone level in blood plasma was reduced. Painful stimulation of animals with the destructed midbrain tegmentum revealed the functional insufficiency of the supraoptic hypophyseal neurosecretory system (SHNS). The results obtained permit considering that the paramedian midbrain tegmentum exerts a modulating influence upon the SHNS function during stress.

Eighty-five cases of hemangioblastoma of the spinal cord are reviewed, including five new ones. While current views of the incidence, histology, and cytogenesis are presented, the main purpose of this article is to call attention to the identifying clinical and radiological characteristics of these spinal tumors. Median age at onset of symptoms was 30 years. The ratio of men to women was 1.1:1. Presenting symptoms were usually radicular pain or posterior column sensory loss or both. The lesions were most often single (79%), intramedullary (60%), and located in the cervical or thoracic spinal cord. There was associated syringomyelia in 67% of intramedullary cases and meningeal varicosities in 48% of all cases. Lindau disease and hemangioblastomas in other central nervous system locations were present in 33% of cases. The characteristic roentgenographic picture is a densely vascular tumor in association with a larger avascular syrinx and meningeal varicosities. Surgery is the only definitive treatment.

A discrepancy between complaints of varicose veins of the legs such as stabbing in the legs, pain in the legs, tiredness of the legs, heaviness of the legs, feeling of swelling in the legs and nocturnal cramps in the calves, and anatomical signs of varicose veins in the legs was observed. Therefore these complaints were analyzed in 345 antenatal patients regarding their psychological aspects. No complaints of venous insufficiency were found in 47% of the pregnant women. Of the 53% antenatal patients with complaints, 24% had mild, 18% had moderate and 11% had severe complaints. Antenatal patients with well noticable neurotic personality traits in the MPI had complaints twice as often as women without neurotic traits (p smaller than 0.05). Introverted antenatal patients (according to the MPI) had more venous leg complaints than expected (p smaller than 0.05). Pregnant women with frequent psychosomatic complaints and altered general well being had the highest incidence of varicose veins complaints (p smaller than 0.001) or p smaller than 0.05). In addition to these psychometric data, there was also a correlation of the gynaecological history with complaints of venous insufficiency in the legs during pregnancy. Pregnant women with a very painful menarche had more varicose vein complaints than expected (p smaller than 0.05). The incidence was also higher with a history of abortion (p smaller than 0.05), marked dysmenorrhea (p smaller than 0.01) and side effects from oral contraception (p smaller than 0.01) and in primigravida (p smaller than 0.05). Age was only correlated to the symptom of stabbing pain in the legs in a statistically significant correlation (p smaller than 0.05). The results were tested statistically for significance with the X2-method.

For a patient suffering with his legs, the pain is usually associated with the presence of one or more varices that can be seen. The physician must not fall into this trap. Questioning is vital. Establishing the kind of pain and the conditions under which it occurs may elok for (1) a rheumatological etioloty: sciatic or crural nerve pain, calcaneal pain: (2) a surgical etiology: an inguinal or particularly a crural hernia, a popliteal cyst; (3) a medical etiology: exogenous polyneuritis, hypokalaemia resulting from the abuse of laxatives or of diuretics, etc.
