Lege Artis Medicinae - 2016;26(04)

[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.]

[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.]

[What does the „whole”-ness of patients with diabetes mellitus mean?]

VÁLYI Péter

[Diabetes mellitus is a chronic, progressive disease, characterized by elevated levels of blood glucose, can lead to many complications and can increase the overall risk of early disability and dying prematurely. The newest guidelines on management of patients with diabetes mellitus give a full description of diagnostic criteria, prevention, lifestyle and pharmacological treatment, complications, age-related characteristics. However, in everyday care of patients with diabetes mellitus little attention is paid to severity of anatomical and functional impairment related to disease, how and in what extent those limit everyday activities, restricts filling the social role, the importance of interrelationship of a human being and environment, to personal factors. The aims of this publication is: to present how diabetes mellitus influences the entirety, the “whole”-ness of a human; to show tools of objective estimation of impairments and changes of functionality; to call attention to importance of development of residual abilities, of shaping supportive environment, of assessment of needs, of positive influences of personal characteristics; to demonstrate how all these measures improve quality of life and compliance of patient with diabetes mellitus. The holistic approach of “human’s whole-ness” can contribute to success of preventive, curative and rehabilitative measures in patients with diabetes mellitus.]

[MC world - a board game of medical communication]

KOLLÁR János

[In 2015 in the Institute of Behavioral Sciences of Semmelweis University a board game named MC World (Medical Communi­ca­tion World) was designed to further student learning in the field of medical communication by gamifying the learning material. 29 Hungarian and 28 foreign students were participating in a study where the acceptance of the game and its attitude change effect regarding medical communication were tested. The participants evaluated statements in connection with the game on a 5 point Likert-type scale. The survey responses suggest that both the Hungarian and the foreign medical students considered the application of the game in education as a practical and successful initiation. It draws the attention to better utilization of gamification as an educational facilitator and as a positive opinion forming opportunity.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

[Introduction - Stroke is the third leading cause of death worldwide (following cardiovascular and cancer mortality) and associated with serious disability for the vast majority of patients. There is no salvage therapy for irreversibly damaged brain areas, improving the circulation of the surrounding hypoperfused territories may be associated with benefitial clinical states. Cerebral hypoperfusion may play a role in the pathogenesis of other kind of neurological diseases, improvement of global circulation may have a preventive effect on these conditions. Aims - The aim of our study was to review the experimental and clinical articles focusing on the role of vinpocetin in different neurological conditions. Results - Vinpocetin appears to have several different mechanisms of action that allow for its antiinflammatory, antioxidant, vasodilating, antiepileptic and neuroprotective activities in experimental conditions. On the other hand, several meta-analysis of the existing studies in acute stroke examining short and long term fatality rates with vinpocetin was unable to assess efficacy. In chronic cerebrovascular patients, vinpocetin improves impaired hemorheological variables, has significant vasodilating properties, improves endothelial dysfunction, neuroimaging studies showed selective increase in cerebral blood flow and cerebral metabolic rate, all of which are potentially beneficial in cerebrovascular disease and may improve cognitive functions. Summary - Based on the above mentioned results vinpocetin plays an important role both in basic research and in clinical management of different neurological diseases.]

[Complications of infusion treatment with emphasis on extravasation of cytostatics]

HARISI Revekka

[The extravasation of cytostatics is the most signifi cant complication of infusion therapy in cancer treatment. Extravasation refers to the inadvertent infi ltration of cytostatic drugs into subcutaneous or subdermal tissues surrounding the intravenous or intraarterial administration site. According to literature data incidence estimates between 0,01-7%. Extravasated drugs are classifi ed according to their potential for causing damage as vesicant, irritant and nonvesicant. Knowledge of risk factors, the patientrelated and treatment-related ones is important to minimize the occurrence of extravasation. In order to reduce the risk of extravasation, the staff involved in the tumor infusion therapy must be specially trained to implement several preventive and therapeutical protocols. In 2012, ESMO-EONS has put together a new comprehensive treatment protocol on the topic of cytostatics extravasation. Protocol recommended that every oncological department, who administers chemotherapy have to have extravasation trained team and a standby extravasation kit. According to the new ESMO-EONS guideline subcutaneous corticoids are not recommended, anymore. In case of mechloretamine extravasation the recommendation is immediate subcutaneous injection of sodium thiosulfate. After extravasation of anthracyclines, mitomycin C and platin salts the best treatment opportunity is subcutan dimethyl sulfoxide administration. In case of anthracyclines’ extravasation intravenous dexrazoxane treatment is also effective. Hyaluronidase, injected into or under the skin, facilitates absorption of extravasated drugs because of increases connective tissue permeability, promotes the spreading and reduces the local concentration of the extravasated citostatic agents. Hyaluronidase might be effi cacious in preventing skin necrosis by extravasation due to vinca alkaloids. The treatment of unresolved tissue necrosis or pain lasting more than 10 days is surgical debridement. Because of the medical and juristic importance of the extravasation event, it is necessary to establish uniform guidelines for treatment of extravasation, in all Hungarian Oncological Centers.]
