JULY 29, 1992

Lege Artis Medicinae - 1992;2(07)

[The development of the tissue banking techniques has made possible the production of wide range of differently preserved collagen based tissue grafts (skin, bone, dura mater, fascia lata). Excellent clinical results have been obtained by the application of allogeneic and xenogeneic grafts. The article summarizes the activity fields of tissue banks in the USA and in Europe. The review presents the most important aspects of tissue banking, antigenicity, sterility, preservation and storage of different grafts. ]

[The role of prostacyclin in the function of the gastric mucosa]

BÁLINT Gábor Sándor

[The intracellular effect of exogenously admi nistered prostacyclin in the gastric mucosa seems to be a polyphasic one, namely: 1. effect on the cyclic nucleotide (CAMP, CGMP) turnover, 2. effect on the calmodulin-content, 3. DNA and RNA changes 4. influence on protein synthesis 5. new cell formation. Besides the endogenous prostacyclin exerts a natural protection against damaging noxae, thus maintaining the physiological integrity of the mucosa. ]

[What is the cause of delay in the diagnosis of the primary sjögren's syndrome?]


[Primary Sjögren's syndrome is the most frequent polysystemic autoimmune disease after rheumatoid arthritis. Keratoconjunctivitis sicca and xerostomia are characteristic of primary Sjögren's syndrome but the evolution of these signs may exist for years, and only one of them may be observed for a long time. Arthritis and enlargement of the parotid and submandibular glands are rarely observed as first symptom. The diagnosis of primary Sjögren's syndrome is based on the evaluation of the obligate signs. Clinical experience shows that there are many patients with undiagnosed Sjögren's disease. The authors would like to demonstrate the importance of the characteristic sings of primary Sjögren's syndrome, and the clinical and immunoserological tests which are useful in the diagnosis of the disease.]

[Clinical principles in the diagnosis and therapy of disseminated intravascular coagulation]

SAS Géza

[Psychologically intravascular coagulation of the blood is hampered by the endothelium, the inhibitors of the coagulation system and the circulation as well. Various pathological events may the diffuse activation of the blood coagulation factors causing disseminated intravascular coagulation. The two main consequences of the DIC are ischaemia in the organs concerned and the consumption of the blood coagulation factors. The activation of the fibrinolytic system improves the former though aggravates the latter pathological events. In the prevention and therapy the effective treatment of the basic disease is of primary importance. Thorough evaluation of the clinical symptoms and the laboratory data can help in the diagnostics. Heparin can be administered only in the hypercoagulative-consumptive forms of the DIC if bleeding does not exist actually. In recent years, the administration of the anti thrombin concentrate has come into prominence because it can promote the restitution of the coagulation system without increase of bleeding. Antifibrinolytic (Gordox) therapy is advised only in cases of extreme hyperfibrinolytic activity. ]

[Laboratory diagnosis of disseminated intravascular coagulation]

HORVÁTH Andrea Rita, MUSZBEK László

[Disseminated intravascular coagulation (DIC) is a highly dynamic process with a broad spectrum of clinical manifestations and laboratory findings. There is no specific laboratory test for the diagnosis of DIC. For the reliable diagnosis of DIC we recommend a test-panel which can be divided into three groups: 1, The screening tests include the measurement of prothrombin time, activated partial thromboplastin time, trombin time, platelet count and detection of fibrin monomers; 2, The diagnosis of DIC can be confirmed with the help of additional assays, such as the determination of fibrin degradation products, antithrombin III or the detection of fragmentocytes in peripheral blood smear; 3, Special tests such as determination of clotting factors, reptilase time, activation peptides and thrombin-antithrombin III complexes may serve as useful tools in the differential diagnosis and in the scientific evaluation of the mechanisms of DIC. In this paper the advantages and disadvantages of different laboratory tests used in the diagnosis of DIC are also critically evaluated. ]

[Cardiac Arrhythmia Suppression Trial]


[ Arrhythmia-related death and non-fatal cardiac arrest were 4.5% in the encainide and flecainide group (33 out of 730 patients), compared with only 1.2% in the placebo group (9 out of 725). The relative risk was found to be 3.6%. The overall mortality rate was also higher in the group treated with active agents (7.7%) than among those treated with placebo (3.0%). The relative risk in the latter group was 2.5%.]

[Chemotherapy of multiple myeloma]


[Multiple myeloma is a multifaceted haematological disease, a plasma cell malignancy that may pose an oncological differential diagnostic challenge. The importance of this disease is emphasized by its incidence. Since there are multiple novel therapies available for myeloma patients, decade-long survival in not uncommon; therefore, myeloma patients provide a signifi cant part of the patients referred to hematological clinics. In this review, fi rst the novel diagnostic criteria are introduced, followed by the standard therapeutic approaches for transplant-eligible and ineligible patients. As the disease nearly always relapses, the later line therapies available in this malignancy are presented with a special emphasis on the Hungarian haematological practice.]

[Hungarian Vasculitis Registry – results of the first five years]

HARIS Ágnes, TISLÉR András, ONDRIK Zoltán, FILE Ibolya, MÁTYUS János, ZSARGÓ Eszter, DEÁK György, AMBRUS Csaba

[Launching the Hungarian Vasculitis Registry aimed to collect information about prevalence and outcome of our patients with ANCA-associated vasculitis, and treatment protocols of the disease. The on-line data collection has been developing dynamically since its initiation five years ago, presently 278 patients’ files are available. Patients’ mean age is 58.2±14.5 years, 62% are women; their disease is associated with c-ANCA positivity in 51% and p-ANCA in 49%. At diagnosis GFR was 24.6±21.6 ml/min/1,73 m2, that time 29%, during the total follow up 39% of the registered subjects needed dialysis. Renal replacement therapy could be discontinued in 23% of them. In cases with focal histological changes, also with upper respiratory tract and skin involvement dialysis was significantly less frequently necessary, which underlines the importance of early diagnosis. In induction therapy steroid was administered for 94% of the patients, 85% of them got cyclophosphamide, 59% was treated by plasmapheresis, 11% got rituximab. Maintenance treat ment contained steroid in 80%, per os cyclophosphamide in 23%, parenteral cyclophosphamide in 22%, furthermore 40% of the patients got azathioprin, 8 subjects got mycophenolate and 6 got methotrexate. Median follow up was 30 months (IQR 6-78), during which period 20% of the patients died, 5% got kidney transplantation, and 5% were lost to follow up. Median survival was 14.8 years, five years survival was 85%, and ten years survival was 70%. Long term survival in patients with c-ANCA vasculitis seemed better comparing to p-ANCA vasculitis, but when correcting by age this difference disappeared. Predictors of death were age and dialysis dependent renal failure. Relapses developed in 27% of patients, 28% of them presented in the first year, 21% suffered it after five years of care. Collected data by the Hungarian Vasculitis Registry shows our society’s successful professional activity. Our results are comparable to the published data in the literature, yet there are several areas in our care where further improvements are warranted in order to increase our patient’s survival and quality of life.]

[Abdominal and thoracal manifestations of posttransplantation lymphoproliferative disorder in children]


[INTRODUCTION - Posttransplantation lymphoproliferative disorder is a secondary disease of transplanted patients, usually with good response to reduction of immunsuppressive therapy. PATIENTS AND METHODS - The lymphoproliferative disorder was diagnosed in four children among 139, renal, liver and lung transplanted patients. Clinical data (original disease, transplanted organ, age and time elapsed since transplantation at the diagnosis of the disorder) and imaging findings (chest X-ray, thoracal and abdominal computed tomography scans) were analysed retrospectively. RESULTS - Thoracal and abdominal forms were the most frequent manifestations of posttransplantation lymphoproliferative disorder in our patients. Following features have been diagnosed on imaging studies: multiple liver nodules (two cases), multiple nodules in the renal parenchyma (two cases), splenomegaly (two cases), bowel wall thickening (two cases). Retroperitoneal and mesenteric lymph node enlargement was found in all patients. Thoracal manifestations were as follows: mediastinal lymphadenopathy (two cases), hilar mass (one case), multiple pulmonary nodules (one case). Renal rupture with perirenal hematoma in one case, hilar mass envolving the main bronchus in one case, hepatic abscesses necessitating drainage in one case, and bowel wall necrosis in one case were the complications of posttransplantation lymphoproliferative disorder. CONCLUSION - Presenting symptoms are aspecific, often mimicking infection. Posttransplantation lymphoproliferative disorder has to be excluded if aspecific symptoms in a transplanted patient are present, or the patient does not react properly on antibiotics. First step investigations include chest X-ray and abdominal sonography. Neck, chest and abdominal CT are mandatory for detecting all manifestations, for staging the disease and to determine the best localization of obligatory biopsy.]

[Oncological treatment on certain special cases]

FUTÓ Ildikó, HORVÁTH Dorottya Katalin, LANDHERR László

[Even in the absence of clinically signifi cant co-morbidities, cancer care is a major challenge for both patients and healthcare professionals. Routine anticancer treatment may be complicated by special clinical situations such as pregnancy or organ transplantation. The dosage of certain oncotherapy agents may be further affected by impaired renal and hepatic function or diabetes mellitus. These days, given the improved prognosis of cancerous diseases and increased survival, personalized therapy and prevention of long-term side effects is becoming particularly important, especially in the above-mentioned oncological situations. In this summary, we review the anticancer treatments recommended by ESMO in specifi c clinical situations.]
