[10 years' of production and use of human rabies immunoglobulin in Yugoslavia].

Application of the rabies immunoglobuline is a compulsory part of the prophylaxis of rabies in all severe, transdermal lesions caused by rabies infected animals. Sylvatic rabies has spread in the past few years throughout the whole Yugoslavia, and human cases of rabies have also been reported in other East European countries. In order to achieve the highest level of rabies prophylaxis, apart from postinfective rabies vaccination, it is necessary to provide passive immunization using specific antibodies against rabies. After successful immunization of the young, healthy volunteers in 1990, National Blood Transfusion Institute, in cooperation with the Pasteur Institute from Novi Sad, prepared the first quantities of immunized plasma by plasmapheresis procedure and human rabies immunoglobuline. Without national production, sufficient quantities of human rabies immunoglobuline could not be provided, since the price on the world market is rather high (over $1000 per patient).

Biochemical evaluation of patients with acute pancreatitis.

In this study we determined the clinical accuracy of alpha2-macroglobulin, alpha-amylase, C-reactive protein, lipase, non-esterified fatty acids, pancreatic alpha-amylase and phospholipase A in the diagnosis and prognosis of acute pancreatitis in a group of patients with acute abdominal pain using receiver operator characteristic curve analysis. We investigated 59 patients with acute pancreatitis and 72 patients with extrapancreatic diseases of gastrointestinal origin. On the basis of initial enzyme activities, at cut-offs of 245 U/l for amylase, 656 U/l for lipase, and 182 U/l for pancreatic alpha-amylase, the diagnostic efficiencies were 0.993, 0.980, and 0.975, respectively. Receiver operator characteristic curve analysis showed the same diagnostic accuracies. We evaluated the accuracy of serum alpha2-macroglobulin, C-reactive protein, non-esterified fatty acids and phospholipase A for differentiation between acute necrotizing pancreatitis and acute oedematous pancreatitis. C-reactive protein had the highest prognostic accuracy of the parameters studied (the area under curve = 0.9082) and at a cut-off value of 126 mg/l, sensitivity and specificity were 0.759 and 0.912, respectively. The role of the clinical laboratory in the investigation of patients with acute pancreatitis continues to evolve and biochemical parameters are a good diagnostic and prognostic option.

Spasmogenic action of beta-lactam antibiotics on the gastrointestinal tract of experimental animals.

We have investigated the effects of beta-lactam antibiotics on isolated preparations of rat fundus, ileum, and the body of feline stomach. Isotonic changes of isolated preparations were recorded. Benzylpenicillin (EC50 = 1.31 +/- 0.13 x 10(-5) M), ampicillin (EC50 = 2.16 +/- 0.15 x 10(-5) M), cefotaxime (EC50 = 1.33 +/- 0.15 x 10(-5) M), ceftriaxone (EC50 = 4.39 +/- 0.13 x 10(-5) M) and ceftazidime (EC50 = 1.42 +/- 0.01 x 10(-3) M) produced concentration-dependent tonic contractions of rat fundus. Rat ileum and feline stomach did not respond on these substances. Lidocaine (2.3 x 10(-5) M) and physostigmine (1.0 x 10(-8) M) significantly potentiated contractions produced by benzylpenicillin. On the other hand, methysergide (1.4 x 10(-7) M) and atropine (9.6 x 10(-9) M) significantly blocked tonic contractions produced by benzylpenicillin. Effects of beta-lactam antibiotics on smooth muscle isolated preparations were tissue and species dependent, indicating selectivity of their action.

[Dopamine receptor subtypes].

Dopamine is a neurotransmitter in both central and peripheral nervous system. In the central nervous system dopamine is involved in regulation of: movements, emotional processing of sensory input, appetite, vomiting and secretion of anterior pituitary hormones. The most important peripheral effect of dopamine is control of splanchnic and renal blood flows. There are five subtypes of dopamine receptors. D1 receptors are responsible for majority of peripheral dopamine effects; in the brain they modulate activity of limbic system. Symptoms of schizophrenia are produced by increased activation of D2 and D4 receptors. On the other hand, Parkinson's syndrome could be induced by D2 receptors blockade. D3 receptors decrease craving in drug-dependent laboratory animals. Although D5 receptors were found in many brain regions and in peripheral blood lymphocytes, their functions remain unknown. Linking dopamine receptor subtypes with actual effects of dopamine will enable more selective therapy of disorders caused by malfunction of this important system.

Problems in diagnosis and treatment of cholesteatoma in children.

Our clinical study includes 56 cases of cholesteatoma in children aged 3-14 years, treated in a 6-year period. Cholesteatoma was localized in attic (6 cases), in middle ear (6 cases), in attic plus middle ear (16 cases) and in attic + middle ear + mastoid (28 cases or 50% of the total number). In the surgical treatment combined approach tympanoplasty (intact canal wall technique) was used in 76.8%, radical tympanomastoidectomy in 16.1%, and other techniques in 7.1%. Intact ossicular chain was found in 25%. Reconstruction of the ossicular chain (including autograft, homograft and allograft material) was done in 59%, and the remaining 16% were treated by classic radical surgery. Hearing results: unchanged, 48%; improved, 45%; slightly worsened, 7%; and no dead ear. Recurrency in 31% is considerably higher as compared to 15% in adults found in another comparable study by us.

[Injuries in Vojvodina 1989].

Trauma has all sociomedical characteristics and importance which line up it in the leading problems of the contemporary medical pathology. Injuries are among the first five groups of the diseases in the structure of overall outpatient's morbidity (general medicine 4.05%, occupational medicine 7.57%, pediatric medicine, 1.84% and health service for pupils 4.96%) and are a significant cause of hospitalization. Concerning the very thorough and all-inclusive follow up of all aspects of trauma it is necessary to establish the regional register of injury and intoxication.

[Intra-abdominal hemorrhage in splenic injuries].

The authors present a series of 36 patients operated on for severe intraabdominal bleeding due to spleen trauma. Patients were treated from 02. December 1987 till 30. June 1988 in Emergency Center-Surgical Clinic-University Clinical Center Belgrade (Institute of digestive pathology). The standard operative procedure has been removal because splenic salvage is unreasonable if there is ungoing bleeding and multiple associated injuries. Splenectomy was performed in 32 (88 percent). Overall mortality rate was 9%. Authors want to stress out the role of team in successful treatment of polytraumatized patients.

[Surgical treatment of polytrauma].

This report is based on the review of 230 victims of multiple injuries, treated during 8 months period. There were 156 casualties with dominant Chest and Abdominal injuries. In the immediate treatment of these patients we applied modification of an original scheme by Schweiberer. We also introduced our own procedure of life-saving measures of high priorities. In evaluation of the most accident victims governed by priority of the severity of the multiple injuries, a complete, orderly examination by X-ray, Ultrasonic and CT scanning was undertaken.
