[Metoprolol treatment in dialated cardiomyopathy]

DÉKÁNY Miklós, NYOLCAS Noémi, FIÓK János, VÁNDOR László, SEREG Mátyás, BALOGH Ildikó

[Authors applied metoprolol for treating heart failure in with dilated cardiomyopathy. Patients were given digitalis, diuretics as well as ACE-inhibitor and vasodilator drugs. The grade of heart failure was according to NYHA classification in the mean 2.5 class. For assessing the effect of metoprolol clinical variables and results of non-invasive tests were evaluated and compared in 3 consecutive periods: 1) before starting metoprolol, 2) 2–4 weeks after reaching its definitive dose (short-term effect), 3) 3-6 months later (medium-term effect). Early intolerance appeared in 3 patients; signi ficant progression of heart failure in 2 and hypotension causing complaints in 1. Evaluating the actually treated 17 patients clinical signs of heart failure (NYHA class) decreased, left ventricular ejection fraction improved, though not significantly in case of every considered variables, left atrial filling pressure decreased, exercise capacity did not alter, rate-pressure product decreased at rest and at low level of exercise as well. The authors stress the significance of "up-regulation" of myocardial beta-1 receptors in the reduction of myocardial toxic catecholamin effect and myocardial oxygen demand as well as in the increase of myocardial blood supply. Referring to the data of the respective literature and to their own experiences the authors suggest metoprolol treatment in cases of dilated cardiomyopathy, where previus therapy did not prove to be efficient.]

[Role of oxygen derived free radicals during myocardial reperfusion]

KÓNYA László , FEHÉR János, JUHÁSZ Nagy Sándor

[Oxygen derived free radicals are now considered to be important contributors to tissue (myocardium) injury associated with ischemia and reperfusion. Normaly the tissue concentration of these toxic intermediate products of oxygen is strietly limited, but production of oxygen free radicals overwhelming the capacity of the tissue elimination may cause serious damage. Thus reperfusion has it's own danger with the extension of the injury produced by the ischemia alone. Several experi mental studies have shown that different free radical scavengers can reduce the post-ischemic tissue injury, however, there are contradictory results and unresolved problems. Further investigation is necessary to establish the relevance of oxygen free radical mediated myocardial injury and the effective antioxidant treatment. ]

[Autoimmunity and the network of the antibody-forming cells: the "immunological homunculus"]

UHER Ferenc

[Frank M. Burnet's clonal selection theory declares the deletion and/or anergy of self-reactive clones to be the fundamental mechanism responsible for self tolerance. There is ample evidence, however, that all healthy individuals have lymphocytes and , natural” antibodies that recognize self structures. In the 1970s, Niels K. Jerne postulated the network theory. It is based on the idea that the idiotype, the region of an immunoglobulin that is unique because it comprises the antigen-binding portion of the molecule, can act as both antigen and antibody within the same individual. Network theory views the immune system as a single, highly interconnected system, through idiotypes, a web of V domains. Antonio Coutinho adressed this problem and divided the repertoire of the B lymphocytes into two parts. He suggested that a set of naturally activated cells and the immunoglobulins they secrete, is reflected in the autonomous immune activities of the self-related network as the central immune system. In contrast, immune responses to external antigens are essentially allonomous clonal activities of another set of resting, rapidly turning over lymphocytes that follow the predictions of the clonal selection theory, making up the peripheral part of the system. Finally, Irun R. Cohen suggested that some, perhaps all, major autoantigens are indeed dominant because each one of them is encoded in the organizational structure of the immune system. This picture was termed the immunological homunculus by its analogy to the picture of the body encoded in the central nervous system. ]

[Modern therapy of intracerebral and subarachnoidal hemorrhages]

LEEL-ŐSSZY Lóránt

[The frequency of the intracerebral hemorrhages among the strokes is most commonly quoted around 10 percent. The rupture of an intracranial aneurysm is often complicated with subarachnoideal hemorrhage as well as with intracerebral hematoma therefore this latter type of intraparenchymal hemorrhage may also be discussed in this topic. The modern imaging procedures (Computed to mography, Nuclear magnetic resonance) are of crucial importance in the urgent and exact diagnosis of intracranial hemorrhages. The first essential step in the diagnosis of stroke is to distinguish the ischemic lesion from the hemorrhage by means of CT. When an intra cerebral hemorrhage threatens life and the patient's condition is relatively good there must be an urgent decision considering the choice between medical therapy or surgical intervention. Although clearcut indications for surgery are now available, the clinical and computed tomographic guidelines play indi vidually an important role in the final decision. The individual judgment is always desirable in every case of intracerebral hemorrhage as well as in the surgical intrvention of intracranial aneurysm during the acute phase (two days).]

[Sonography of the shoulder joint]

MORVAY Zita, CSÓKÁSI Zsolt

[Sonography is the most simple, unexpensive and common method in the evaluation of the soft tissues surrounding the shoulder joint. 67 sonographic findings of 61 patients are discussed. Laesions of the rotator cuff, the bursa, the long head of the biceps and the deltoid muscle are demonstrated. Sonography is the first method of choice in the evaulation of the shoulder joint, though it has ist limitas well. ]

[Current diagnosis and treatment of idiopathic intracranial hypertension]

SALOMVÁRY Bernadett, PÁNCZÉL Gyula, MARKIA Balázs, NAGY Gábor

[Background - Idiopathic intracranial hypertension is cha-racterized by raised intracranial pressure of unknown origin, leading to persisting visual loss if left untreated. Purpose - We assessed timing of surgery, and the efficacy and safety of ventriculo-peritoneal shunt. Methods - Retrospective analysis of 65 patients treated at our Neuro-ophthalmology Clinic between 2009 and 2017. Patients - We treated 15 children and 50 adults, 42 patients conservatively, and 23 surgically. The median age at presentation was 27 years for adults, 88% were obese, and 86% female. The age of children was 5-17 years, 40% were obese, and 53% girl. The commonest presentation symptom was headache in both groups (64%), followed by obscuration (33%), and double vision (22-31%). Subjective visual loss was only experienced in the surgical group (50%). The time until diagnosis was 2 weeks in both groups. However, the conservative group presented to our institute significantly earlier (3 weeks), than the surgical group (8 weeks). The follow-up time was 25 months. Results - In the conservative group papilla edema was 2D, visual acuity ≥0.7, and visual field loss was only mild. Time to cure was 3 months. In the surgical group both preoperative papilla edema (3D), and visual function were significantly worse. Indications for surgery were papilla edema, deteriorating visual function or relapse resistant to conservative treatment. Papilla edema disappeared 3 months after surgery, and visual field deficit improved significantly. We detected significant improvement in all aspects of visual function even at first neuro-ophthalmic control 4 days after surgery. However, visual acuity only improved in cases of preoperative acuity ≥0.3. Shunt revision occurred in 17%, and shunt infection in 8.5%. One patient suffered from persistent visual deterioration after surgery, and asymptomatic complication (epidural hematoma) was found in another patient. There was no surgical mortality. Conclusions - This is a curable condition with early diagnosis and adequate treatment, and persistent visual loss can be prevented. Surgery is effective and safe, close neuro-ophthalmic monitoring is mandatory for its optimal timing. Visual function of all patients can be preserved when operated on in time, whereas severe visual loss appears to be irreversible despite surgery.]

[Novelties in the management of Hodgkin lymphoma]

ILLÉS Árpád, MOLNÁR Zsuzsa, MILTÉNYI Zsófia

[Hodgkin lymphoma is a lymphoproliferativ disease, it is about 12-18% of all lymphomas. It has typical morphologic, clinical and therapeutic features, which can distinguish from other lymphoma types. Due to risk- and PET/CT adapted treatment Hodgkin lymphoma is a curable lymphoma with an 80-90% long-term survival, however, refracter- and relapsed patients’ therapy is a great challange. Cure rate can increase due to the development of the diagnostic and treatment modalities, but the use of standard recommendation is necessary. The aim of this review is to show new WHO 2016 lymphoma classifi cation, role of the new diagnostic options, especially 18FDG-PET/CT, Lugano classifi cation and fi rst-line and salvage therapeutic possibilities and to introduce the immunotherapy, like brentuximab vedotin and PD1 inhibitors. Certain points of hemopoietic stem cell transplantation will be also covered.]

[Haemophilia today]

KARDOS Mária

[Haemophilia is the most well-known inherited bleeding disorder, which has an X-linked inheritance and affects men. Its severity is classified on the basis of the amount of circulating functional clotting factors: patients with values < 1% have severe disease, those with values of 1-5% have moderate disease, and those with values >5% are classified as having mild disease. Severe haemophilia is characterised by frequent, spontaneous bleeding episodes, whereas in those with moderate or mild haemophilia, bleeding is only caused by trauma or surgery. Although bleeding can occur almost anywhere, the most common clinical manifestation is haemarthrosis. Haemophilic arthrpathy that develops as a result of repeated episodes of joint haemorrhage is the most important factor of morbidity in those with haemophilia. Intravenous replacement of the missing clotting factor is used to treat and prevent bleeding episodes. Controlled therapy at home that provides immediate replacement is the optimal early approach. Prophylaxis includes administration of clotting factors at regular intervals to prevent bleeding, which must be the main goal of management until a cure becomes available. The development of inhibitors during treatment is the most significant complication of factor replacement, and management of bleeding in patients with such inhibitors is difficult.]
