[Epidemiology of breast cancer]

JUHÁSZ Lajos

[In 1987 breast cancer occupied the 3rd place among female cancers in the world. In Hungary, 13.577 women died due to cancer in 1990, 15,4% from breast cancer. The author uses international, and Hungarian data (at the country and county level) and also the data from his own research results. Incidence of breast cancer has risen continuously and shows a wide range in different parts of the world from 14,1 %000/year to 121,2%8000/year. The 5 year crude survival rate is between 40–65% and is slowly improving. In addition to the well-known risk-factors, the author emphasizes the role of mastopathy because in his patient group of 843 cases 2,3%, but in the mastopathy group 4,1% developed cancer. Therefore, this alteration should be considered as a high risk factor. Among close female relatives of breast cancer patients breast and other cancer has occurred much more frequently, than in that of a control group. Prostate cancer occurs significantly more frequently among 1 st degree male relatives. Therefore it is necessary to study the risk factors with epidemiologic methods and to broaden screening, detection and therapy in order to reduce the incidence and mortality of breast cancer. ]

[Brest cancer screening, early diagnosis]

LENGYEL László

[There is no data in the medical literature concerning the late results of breast physical exam by paramedical personnel as a screening test. In a population screening for breast cancer in Debrecen, nearly 70 thousand women were observed from 1981 to 1985 and 298 new breast cancer patients were detected. 198 patients were from the screened population and 100 patients from the non screened population. All of the breast cancer patients were followed up, and the analysis was completed on 31st December 1991 with the help of statistical methods. The author analysed the overall survival, cumulative death rate and relative risk of dying according to age group. The difference of overall survival was 29% for the screened group. This result is nearly the same as that produced by mammographic screening.]

[Diagnostics of breast cancer]

PÉNTEK Zoltán

[The author interpretes and evaluates the diagnostic methods of breast cancer. Detailed description is given on physical examination, mammography, ultrasound examination, cytology, histology and miscellaneous methods, expressing their advantages and drawbacks. On clinical experience nowadays the combinative application of these by the same expert seems to be the most effective method, possibly in large breast clinic centres.]

[Breast cancer markers of prognostic significance]

TÓTH József, SÁPI Zoltán

[Prognosis prediction of breast cancers is difficult, particularly in early clinical stage (1) or in tumors with practically identical histological structure and degree of differentiation (invasive ductal NOS cancer) because node negative tumors of early developmental stage or with identical structure may demonstrate different clinical course. In such cases the steroid hormone receptor content, the prolife rating capacity of the tumor and the so called independent prognostic factors like the onco gene and supressor gene expression (c-myc, C-erbB–2, p53), the growth factor receptor content (EGFr) and the so called differentiation antigens accompanied by low metastatising capacity (MAM–6, nm23) may help the pathologist in diagnostics. Examinations of these markers are planned to be introduced in future diagnostics and contribute to the elaboration of effective treatment schedules.]

[The surgery of breast cancer]

SVASTICS Egon

[The incidence of breast cancer in Hungary is gradually increasing, not only in the elderly due to the increasing average age, but in younger women as well. In the operative stadia (St I-II), the best results can be achieved by a radical surgical intervention and an adjuvant radio-chemo-hormone therapy. The formerly routine radical mastectomies are being replaced by breast conserving procedures which remove the tumour and sacrife only the most necessary surrounding tissues to achieve the best local tumour control. The fundamental basis for this procedure was established by the clinical trials of B. Fisher and U. Veronesi. The practical basis is the circumstance, that owing to better propaganda, more frequent breast self examinations, and better mammographic and cytological facilities, more breast cancer will be recognized in an earlier stage.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]

FARSANG Csaba

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

Effects of valproate, carbamazepine and levetiracetam on Tp-e interval, Tp-e/QT and Tp-e/QTc ratio

YASAR Altun, ERDOGAN Yasar

Aim - To evaluate P-wave dispersion before and after antiepileptic drug (AED) treatment as well as to investigate the risk of ventricular repolarization using the Tpeak-Tend (Tp-e) interval and Tp-e/QT ratio in patients with epileptic disorder. Methods - A total of 63 patients receiving AED therapy and 35 healthy adults were included. ECG recordings were obtained before and 3 months after anti-epileptic treatment among patients with epilepsy. For both groups, Tp-e and Tp-e/QT ratio were measured using a 12-lead ECG device. Results - Tp-e interval, Tpe/QT and Tp-e/QTc ratios were found to be higher in the patient group than in the control group (p<0.05, for all), while QTmax ratio was significantly lower in the patient group. After 3 months of AED therapy, significant increases in QT max, QTc max, QTcd, Tp-e, Tp-e/QT, and Tp-e/QTc were found among the patients (p<0.05). When the arrhythmic effects of the drugs before and after treatment were compared, especially in the valproic acid group, there were significant increases in Tp-e interval, Tp-e/QT and Tp-e/QTc values after three months of treatment (p<0.05). Carbamazepine and levetiracetam groups were not statistically significant in terms of pre- and post-treatment values. Conclusions - It was concluded that an arrhythmogenic environment may be associated with the disease, and patients who received AED monotherapy may need to be followed up more closely for arrhythmia.

[Rehabilitation possibilities and results after neurosurgical intervention of brain tumors ]

DÉNES Zoltán, TARJÁNYI Szilvia, NAGY Helga

[Objectives - Authors examined the rehabilitation possi­bi­lities, necessities, and results of patients after operation with brain tumor, and report their experiences. Method - Retrospective, descriptive study at the Brain Injury Rehabilitation Unit, in National Institute for Medical Rehabilitation. Patients - Patients were admitted consecutively after rehabilitation consultation, from different hospitals, following surgical intervention of brain tumors, between 01 January 2001 and 31 December 2016. Patients participated in a postacute inpatient rehabilitation program, in multidisciplinary team-work, leaded by Physical and Rehabilitation Medicine specialist included the following activities: rehabilitation nursing, physical, occupational, speech, psychological and neuropsychological therapy. Results - At the rehabilitation unit, in the sixteen-year period 84 patients were treated after operation with brain tumor. Patients arrived at the unit after an average of 41 days to the time of the surgical intervention (range: 10-139 days), and the mean length of rehabilitation stay was 49 days (range: 2-193 days). The mean age of patients was 58 years (20-91), who were 34 men and 50 women. The main symptoms were hemiparesis (64), cognitive problems (26), dysphagia (23), aphasia (16), ataxia (15), tetraparesis (5), and paraparesis (1). The mean Barthel Index at the time of admission was 35 points, whereas this value was 75 points at discharge. After the inpatient rehabilitation, 73 patients improved functionally, the status of 9 patients did not show clinically relevant changes, and 2 patients deteriorated. During the rehabilitation 10 patients required urgent interhospital transfer to brain surgery units, 9 patients continued their oncological treatment, two patients continued rehabilitation treatment at another rehabilitation unit, and after rehabilitation 73 patients were discharged to their homes. Conclusions - Inpatient rehabilitation treatment could be necessary after operation of patients with brain tumor especially when functional disorders (disability) are present. Consultation is obligatory among the neurosurgeon, rehabilitation physician and the patient to set realistic rehabilitation goals and determine place and method of rehabilitation treatment, but even at malignancies cooperation with oncological specialist also needed. Authors’ experience shows benefits of multidisciplinary rehabilitation for patients after brain tumor surgery. ]
