Urologic complications after surgery on lumbosacral spine.

Forty-five of 74 patients (60%) postsurgery for disk disease showed findings of neurogenic bladders. Sixty-nine of these patients had no complaints before surgery and presented with complaints only after surgery. We believe this is a high surgical morbidity, and all patients should have a presurgical urodynamic diagnostic evaluation to aid in selection of patients in whom surgery will be most helpful and to establish a presurgical baseline for further postsurgical urodynamic comparison.

Role of alpha and beta adrenoceptors on the salivary secretion in the mandibular gland of the rabbit.

The stimulation of the superior cervical ganglion increased the salivary flow rate (about five-fold) in all 35 rabbits studied but two. The administration of alpha or beta adrenoceptor blocking drugs was unable to eliminate the positive effect of the sympathetic stimulation on the salivary flow, though the flow rate fell about 50% with the administration of each of the blockers. According to these results both types of receptors may be involved in the secretory response of this gland. Nevertheless it seems that the beta-adrenoceptors play a more important role in the secretory response and the alpha-adrenoceptors in the motor one.

Effect of sympathetic stimulation on salivary secretion in submandibular gland in the rabbit stimulated by pilocarpine.

The sympathetic stimulation under slow pilocarpine-induced flow conditions brought about a decrease in this flow rate that could be due to vasoconstriction, since such an effect was not observed after the administration of phentolamine (4 mg/kg i.v.). Contrariwise the injection of a beta-adrenergic blocking agent (propranolol 2-2.5 mg/kg i.v.) produced a decrease of the salivary flow rate that was even greater than in the control animals. These results suggest that the secretory effect in this gland and species is predominantly beta-adrenergic. The stated results are related to the changes observed in the blood outflow from the gland.

Hip fractures in patients with Parkinson's syndrome.

Hip fractures in patients with Parkinson's syndrome present a continuing challenge to orthopaedic surgeons. Sixty-two consecutive such patients have been reviewed. With or without operation, there was very high rate of mortality (31%) and complications. However, the functional results, the ability to walk, progression of the disability, and the quality of life were significantly better after operation. The results suggest that operation is the preferable solution for these patients. They require, however, much more particular care than other patients with hip fractures. This includes adequate adjusted antiparkinson medication, appropriate anesthesia with special attention to adequate ventilation and postoperative analgesia, more intensive respiratory and functional physiotherapy, very meticulous nursing care, and a relatively extended period of preventive antibiotics.

[Comparative study of different serological tests for the diagnosis of brucellosis (author's transl)].

The diagnosis of brucellosis is frequently a difficult one, and it is founded basically on the results of blood cultures and serological tests. Wright's classical agglutination test is commonly utilized in the serological diagnosis of brucellosis and its value is well established in the acute forms of the disease; for the diagnosis of subacute or chronic forms, however, a Coombs test must be performed to show incomplete antibodies. The agglutination carried out with serum treated with 2-mercaptoethanol allows the determination of the type of immunoglobulins present. Indirect immunofluorescence has been infrequently utilized in the diagnosis of brucellosis. The first three tests have been compared with indirect immunofluorescence using sera from 100 patients presenting with fever of unknown origin. All tests were negative in 40 sera, and of the 60 remaining sera only 32 were positive to all four tests. The highest titers were found with the Coombs test, while immunofluorescence yielded titers which were never above 1/320. Significant correlation coefficients were obtained between the tests. The best correlation was obtained between immunofluorescence and 2-mercaptoethanol, followed by immunofluorescence and Coombs, and by immunofluorescence and agglutination. Only immunofluorescence titers above 1/80 corresponded to the same of superior titers in the remaining tests; thus immunofluorescence titers below 1/80 can not be considered as diagnostic of the disease. The authors believe that immunofluorescence to 1/80 can be utilized as a quick routine test for the diagnosis of brucellosis, its disadvantages being a high cost and the requirement for an immunofluorescence microscope which may not be available in many laboratories.
