[Laboratory control of the oral anticoagulant therapy]

VAJDA Zoltán, PÁL András, SIKOS Zita, SAS Géza

[There are two basic requirements in the treatment and prophylaxis of thromboembo lic diseases by chronic anticoagulation with coumarin (Syncumar). The first is the preven tion of a new thrombosis while the second is the avoidance of concomitant bleeding complications. For this reason it is necessary to achieve an appropriate anticoagulation level which can be characterised by labora tory measurement of the prothrombin level. In this paper, the theoretical and practical as pects of the laboratory control of Syncumar treatment are reviewed. The most serious problem is that the prothrombin level (Quick time) determinations utilising thromboplastin preparations from different sources give diffe rent values in the same patient plasma, which makes comparison of data from different laboratories impossible. The paper gives a brief overview of the definition and practical use of the International Sensitivity Index (ISI), characterising the different thromboplastin preparations, and the International Normali sed Ratio (INR) which can be calculated on the basis of the ISI. In spite of unquestionable improvements, the uncertainty about instrument-thromboplastin-ISI relationships reduces confidence in the INR system, especially when differences in INR values have clinical significance. Efforts need to be directed toward providing local, laboratory/instrument specific ISI values. ]

[The clinical significance of amaurosis fugax]

HORVÁTH Sándor, SOMLAI Judit

[The symptoms of amaurosis fugax (transient monocular loss of vision) indicate not only atherosclerotic disease of the ocular or extra cranial cerebral vessels, but also that of the systemic circulation. The prognostic significance of amaurosis fugax developing after the age of 50-55 years is similar to that of transient ischaemic attack of the brain: it could be a harbinger of atherosclerotic disease of the extra- and intracranial brain vessels as well as the coronary arteries. According to the mortality data, patients presenting with symptoms suggestive of amaurosis fugax will die due to heart disease, primarily myocardial infarct. Diagnostic evaluation should include not only ophthalmological, but also neurological and cardiovascular in vestigation to verify carotid and coronary atherosclerosis. Therapy of the whole disease and not just the symptoms will influence life expectancy in patients with amaurosis fugax. ]

[Methylprednisolone pulse therapy in systemic lupus erythematosus]

GERGELY Péter

[The aim of this retrospective study was to assess the efficacy and safety of methylprednisolone pulse therapy. Thirty five patients with severe systemic lupus erythematosus (lupus nephritis, severe hemolysis and antiphospholipid syndrome with central nervous system involvement, arterial occlusion and thombocytopenia) were treated by pulse methylprednisolone, followed by long-term corticosteroid (and cyclophosphamide) therapy. Thirty four patients achieved remission, after a mean of 4.7 weeks, which lasted on average for > 2.7 years. Six patients presented with an exacerbation after 1-2.5 years. Twenty eight patients are still in remission. No side effects were observed during pulse therapy. Methylprednisolone bolus therapy is safe and effective in severe systemic lupus erythematosus, including cases of lupus nephritis and severe central nervous system manifestations, but an appropriate choice of long-term therapy is essential.]

[The value of immunoscintigraphy in patients with metastatic malignant melanoma]

PAPÓS Miklós, LÁNG Jenő, CSERNAY László, SZEKERES Lenke, KUBA Attila

[Immunoscintigraphy with 99MTc-labeled F(ab'),fragments of monoclonal antibody (reactive with a high molecular associated antigen) was performed in patients with malignant melanoma. 24 investigations on 23 patients were carried out. A total of 40 lesions in 23 patients were detected by chest radiography, ultrasound, CT, bone scintigraphy or histology. 24 of the 40 lesions (60%) were visualized by immunoscintigraphy. Following correction of the physiological liver background by digital subtraction, 3 liver metastases were localized. These results indicate that immunoscintigraphy with radiolabeled F(ab')2 fragments can provide clinically useful information. ]

[Methodological letter from the Public Health and Epidemiology Technical College on vegetarian and similar diets in crèches and educational establishments]

[The nutritional status of vegetarians is strongly influenced by the type of diet they eat. While semi-vegetarian and lacto-ovo-vegetarian diets can meet the nutrient needs of young children, provided they are carefully and professionally planned, strict vegetarian or macrobiotic diets may not meet the needs for some nutrients and may be deficient in both children and adults. ]

[Education and psychological support of parents in cases of postnatally detected Down syndrome]

MÁTÉ Orsolya, KÍVÉS Zsuzsanna, OLÁH András, FULLÉR Noémi, PAKAI Annamária

[OBJECTIVE - Since the 60’s several publications dealt with the phenomenon how physicians inform parents of newborns about postnatal recognition of Down’s syndrome and the support they receive right after breaking the bad news. Howe - ver, the rest of these studies concentrated on surveying parental satisfaction, while relatively few international studies deal with the other side of the communicational situation, the opinion of the informer. Our study focused on the circumstances of parental information in Hungarian institutions of obstetrics in order to evaluate the possibilities for interventions. METHODS - The Down’s team operating at the University of Pécs Faculty of Health Sciences carried out a national survey in 2005 - an interview-based questionnaire filled by physicians of institutions of obstetrics - with the help of the National Register for Congenital Diseases of the National Centre for Epidemiology and Down’s Foun dation. RESULTS - The coverage of the survey reached 74%. Rest of the surveyed institutions did not have information protocol, however, 70% of them believes it would be necessary. Only 44% of the physicians received communication training and 81% of them believe they can manage communication, 33% have felt that the mother of a newborn with Down’s syndrome would expect special help that the institutions are unable to provide. CONCLUSION - There are serious problems with the circumstances of parental informing in Hungarian institutions of obstetrics. This situation would obviously require intervention. An aimed communicational training based on international experience and exploiting the openness of physicians, as well as the establishment of information protocol could be elements of such intervention.]
