[Medicus imperitus. The inception of physician liability in classical Roman law]

PÉTER Orsolya Márta

[In an era where the number of medical liability suits is permanently increasing, it might be interesting - in Hungary as well -, and also useful to detect and analyse the roots of such liability in Continental/Euro­pean law. In classical Roman law - that also gives the basis for European ius commune - , we cannot encounter uniform and general norms governing medical liability. The reasons of such hiatus are inherent in the peculiar casuistic method of Roman law, as jurists focused on providing a proper solution for a specific case, and not on developing general and abstract behavioural norms. In addition to the foregoing, the legal status of physicians and their patients was heterogeneous: many doctors were foreign slaves who, if lucky, obtained freedom and Roman citizenship, or settled down in Rome as foreign citizens. The form of their professional liability was also determined by the legal status of their patients: if an untrained or careless physician tried to cure a slave owned by a Roman citizen and failed, the owner could sue the doctor for damaging his property. As far as free patients are concerned, we cannot formulate any unequivocal statements regarding medical liability and malpractice; however, the few available sources clearly prove that a physician who had wilfully caused harm to his free patient resulting in death was severely punished in ancient Rome.]

[Treatment and care of patients with hypertension based on the new professional guidelines]

KISS István

[The 10th professional guideline for treating patients with hypertension written by the Hungarian Society of Hypertension has been released now after thirty years of the first treatment proposition. This summary presents the changing which came to being since then in the risk assessment, the activity in diagnostics and the therapeutic principles, also explaining their significance. Highlighted between the topics are the therapy based on risk assessment, the changing of the target blood pressure, the alteration of therapeutic principles and the combination therapy coming to the front. The birth of new therapeutic frames and their manual interpretation are also important subjects touched upon. The professional guideline’s necessity, value and applicability to practice are also considered and evaluated.]

[Extensive retroperitoneal extramedullary hematopoiesis mimicking disseminated abdominal cancer]

KŐVÁRI Bence, DONKÓ Veronika, PIUKOVICS Klára

[INTRODUCTION - Myelofibrosis is a type of chronic myeloproliferative neoplasia frequently associated with extramedullary hematopoiesis. This latter process usually affects the spleen and the liver, and should be designated as nonhepatosplenic extramedullary hematopoiesis if it involves other organs. Nonhepatosplenic extramedullary hematopoiesis is reported to be more common in patients who had splenectomy. CASE REPORT - A 66-year-old woman with 5-year history of myelofibrosis was hospitalized eight month prior to death due to increasing abdominal effusion, abdominal discomfort and dyspnea. Three years before death, splenectomy was performed. The abdominal imaging studies disclosed a circumscribed tumorous mass in the pancreas, with enlargement of the peripancreatic lymph nodes. The lesion interpreted as pancreatic cancer progressed and the patient died. Post mortem histological evaluation confirmed the abdominal mass to represent myeloid metaplasia of the retroperitoneal fat tissue. CONCLUSIONS - Besides the possibility of a secondary primary tumor, the discovery of a novel mass lesion in patients with myelofibrosis should raise the suspicion of extramedullary hematopoiesis, especially when the patient had splenectomy.]

[Increasing cerebral perfusion pressure in serious cranial injury - contradictory effects of dopamine]

BARZÓ Pál, CZIGNER Andrea, ANTHONY Marmarou, ANDREW Beaumont, DEÁK Gábor, PANOS Fatouros, FRANK Corwin

[Background - Management of cerebral perfusion pressure is an important element of the treatment of traumatic brain injury. Vasopressors are accepted as a method of choice to increase mean arterial blood pressure and thus cerebral perfusion pressure in the face of rising intracranial pressure. There are, however, some unresolved issues and potential risks to this therapy. Matherial and methods - This study therefore examines the effects of dopamine on physiological changes as well as on brain edema and water content that can be readily assessed by MRI/MRS in 1. a rodent model of rapidly rising intracranial pressure, caused by diffuse injury with secondary insult and 2. a model of cortical contusion. Results - Dopamine was capable of restoring cerebral perfusion pressure in the model of rapidly rising intracranial pressure. However, this was associated with only a partial restoration of cerebral blood flow. In the brain tissue two profiles of change in the apparent diffusion coefficient of water (ADCw) were seen; one in which ADCw recovered to baseline, and one in which ADCw remained persistently low. Despite that dopamine did not alter these profiles, MRI-assessed tissue water content was increased four hours after injury and dopamine increased cerebral water content in both subgroups of injury, especially in the subgroup with a persistently low ADCw (p<0,01). In the contusion group dopamine significantly worsened the edema both in the injured and in the contralateral area of hippocampus and temporal cortex even though the ADCw values did not change, except for the contralateral hippocampus, where both water content and ADCw values rose with treatment, suggesting extracellular accumulation of water. Conclusion - The results suggest that dopamine has a double effect - while it temporarily and partially restores cerebral blood perfusion, at the same time it induces an increase in brain swelling and thus an increase in intracranial pressure in some cases. It is possible that in a subgroup of patients vasopressor treatment leads to an opposite effect several hours later. Vasopressor therapy in the clinical setting therefore should be cautiously applied.]

[The concept of epileptic networks. Part 2.]

HALÁSZ Péter

[In this paper we investigate evidences supporting the network concept of epilepsies from different approaches. Firstly the functions of cortical networks in which most of the epileptic networks are embedded, are treated. Then the tentative characteristics of an epileptic network are enumerated and the conversion mechanisms from physiological to epileptic networks are analyzed. Later the role of neuronal oscillations in epileptic networks and aspects of epilepsies provoked by sensory and cognitive tasks is studied. Lastly new fMRI data in mapping BOLD networks underlying spike and seizure discharges are used as arguments in favour of the epileptic network hypothesis. In a second part the well-known epilepsies related, or probably related to physiological networks are shown. Finally consequences of the network approach for creating a new unified epilepsy classification are discussed.]

[Neurological effects of tolperisone]

KOVÁCS Tibor

[Spasticity, as a result of cortical motor neuron injury, is a frequent symptom in neurological disorders. Tolperisone is a centrally acting muscle relaxant, which has been used for 50 years in clinical practice. Tolperisone has a membrane-stabilising effect and it inhibits voltage-gated sodium and calcium channels. Although it targets the central neural system, it has no sedative side effects, in contrast to other muscle relaxants. Besides clinical experiences of past decades, the efficacy of tolperisone has also been proved in a study fulfilling evidencebased criteria. In this double-blind, placebo- controlled, randomised, parallel group study, 78.3% of tolperisone-treated patients had an at least one-point reduction on the Asworth scale (a 5-grade scale used the measure spasticity), compared with 45% in the placebo-treated group. The excellent tolerability of tolpe-risone is demonstrated by the finding that the number of adverse events was greater in the placebo group than in the tolpe-risone group. Taking these facts in consideration, tolperisone is a safe and effective drug to treat spasticity.]

[End state AIDS patient at an intensive care unit - a case report with unconventional lessons]

ORTUTAY András, MARJANEK Zsuzsa, NAGY Károly, RÁCZ József, BARCS István

[A 26 year old male patient with unknown medical background had been admitted at the Department of Anestesiology and Intensive Therapy of the Jávorszky Ödön Hospital in the city of Vác. His HIV positivity had been revealed only at the 8th day of his hospitalization. He was living in a small settlement as an i.v. drug user, unknown to the drug prevention system or the STD primary care providing network. Being an end state AIDS patient, the time of the infection, the number of his contact persons, the source of the infection and the previous epidemiological pathway were not known. With this case report we would like to call attention to the importance of the differential diagnosis of AIDS disease, the role of the proper safety regulations concerning potentially infected and infected persons, the epidemiological importance of undiagnosed infections, and the extension of drug prevention services reachable for all persons in need. ]
