Lege Artis Medicinae - 1993;3(10)

[In the political wrangling over the Public Education Act, less attention was paid to the Higher Education Act, which was negotiated and adopted in parallel. Attention has also been diverted from the paragraphs that define the future of medical education and training in Hungary and the patient care activities of clinics. Yet we believe the law opens the way for major changes, which is why we recall the debates leading up to the final decision. ]

[The surgical treatment of shoulder instability]

BÁLVÁNYOSSY Péter

[The author briefly reviews the static and dynamic stabilizing system and the biomechanics of the shoulder and describes his principles and techniques of the surgical treatment of instability. A modified Bankart procedure is used for recurrent anterior dislocation. Bone blocks are implanted in cases of locked posterior dislocation. Different forms of cranial instability are described as well as partial and total superior glenoidal lesions. The author discusses surgical procedures used in the treatment of these instabilities. Cranial instability leads to impingement syndrome, which results in rotator cuff lesions. These lesions increase instability and the increased impingement leads to further rotator cuff damage. This vicious cycle can be interrupted by surgical intervention.]

[Clinical application of specific antibodies in immunotherapy of transplantation]

PETRÁNYI Győző, PÁLÓCZI Katalin

[In organ and tissue transplantation practice as well as in the therapy of autoimmune, haematological, immunological and oncological diseases, the possibility for applying immunotherapy is occuring more frequently. The paper deals with all those reagents which are primarily of polyclonal or monoclonal immunglobuline origin and play a significant role in the various cell-bound immune reactions on the surface of lymphocytes. In addition to the anti-lymphocyte or/rather anti-thymocyte globuline as well as the Orthoclone (anti-CD3 monoclonal antibody) reagents well known in clinical practice, it also refers to other lymphocyte surface anti-marker monoclonal anti-bodies (anti CD4, -CD8; anti TCR, anti-LFA reagents) under clinical trial. The article reviews the possible uses of the group of immunotherapeutical reagents in the clinical practice of Kidney and bone marrow transplantation. The pharmacological mechanism, side effects, and prospects for a wider use of these reagents in the future are discussed.]

[The origin of serum catalase in healthy subjects and in some diseases]

GÓTH László

[The activity of serum catalase is highly increased in acute pancreatitis, hemolytic disorders and in some liver diseases, but there is no data on its tissue origin. The serum catalase activity was determined by a spectrophotometric assay in healthy subjects (n = 4275) as well as in increased erythropoesis (n = 424), in hemolytic diseases (hemolytic anemia = 12, megaloblastic anemia = 28, Zieve syndrome = 8, hemorrhage = 38), in acute pancreatitis, (n = 111), in liver diseases (fatty liver = 21, alcoholic hepatitis = 42, acute yellow atrophy = 18, toxic hepatitis = 15), and in liver congestion due to cardiac circulatory failure (n = 28). These diseases yielded increased serum catalase activity. This enzyme has no tissue specific isoenzymes, therefore mathematical and statistical approaches were used. The correlation between serum hemoglobin and serum catalase was analysed. The catalase release was estimated from the time activity curves of serum catalase and compared to its tissue equivalent. In healthy subjects about 60 percent of serum catalase derived from the erythrocytes and the rest from other tissues. During enhanced erythropoesis and in hemolytic diseases, similarly to hemoglobin, its source was the erythrocyte pool. In acute pancreatitis also the erythrocytes might be responsible for the increased serum catalase level. in some liver diseases as well as in liver congestion due to cardiac circulatory failure the increase of serum catalase derived from the liver cells. The diagnostic analysis of serum catalase requires the consideration of its increase as well as its origin. ]

[Prenatal follow up of a complex cardiac malformation complicated with complete AV block]

SZABÓ István, CSABAY László, NÉMET János, HAJDÚ Júlia, PAPP Zoltán

[In a congenital disorder of heart development where the complex cardiac malformation is pared with complete atrioventricular block heart rate is stabile between 50–60 beats/min. Transfer of atrial impulses through the AV node is fully blocked and the slow rhythmic heart beat is maintained by a ventricular pacemaker. In a case of such a complete cardiac malformation recognized in week 32 of gestation and the AV block complication caused stabile 57–58 beat/min bradycardia. 2-di mensional, pulsed and color Doppler ultrasonography was used to identify the disorder and to follow up the intrauterine condition of the fetus. Cardiotocography (CTG) could not generate appreciable results at such a low heart rate. During observation no centralization of fetal circulation causing intrauterine hypoxia was recorded. Updated knowledge on the pathogenesis and obs tetrical management of the fetal third degree AV block is also presented. In this case ultrasonography allowed clear-cut identification of the disorder and also ensured correct evaluation of the intrauterine status of the fetus when other diagnostic methods for evaluation were not applicable. ]

[Eurpean Concerted Action on Thrombosis and Disabilities Angioma Pectoris Study]

MATOS Lajos

[Patients with more than 50% stenosis in one or more coronary arteries had significantly higher fibrinogen levels (p<0.0001). Reduced fibrinolytic activity was also observed in patients with coronary artery stenosis, mainly due to higher levels of plasminogen activator inhibitor-1 (PAI). Decreased fibrinolytic activity was strongly associated with diabetes, elevated triglyceride levels, smoking and impaired left ventricular systolic pump function. Cholesterol levels correlated mainly with protein C and plasminogen levels.]

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]
