[Károly Schaffer was first commemorated by his admirers on the occasion of the fortieth anniversary of his literary activity, in October 1927. In his words of thanks, he expressed his pleasure that this occasion had been chosen to welcome him: while the usual anniversaries are determined by external circumstances, often by chance, the date on which one begins one's academic work is closely linked to one's personality.]

[The influence of Károly Schaffer on the development of neurology and neuropathology]

MISKOLCZY Dezső

[He was the child of the sculptor Károly Schaffer; forms and shapes also captured his attention, but behind them he immediately sought content and meaning. His lifework therefore became an example of the close interweaving of facts and ideas.]

[The relationship between lipids in the brain and blood]

BALÓ József

[Changes in the ratio of lipids in the blood to each other, or other changes in the blood, may be followed by abnormal changes in the brain. On the other hand, primary diseases of the brain may cause abnormal changes in the lipids of the blood. Austin's finding that in metachromatic leukodystrophy metachromatic staining lipoids are excreted in the urine is an important finding in the diagnosis of neurological diseases.]

[The works of Károly Schaffer on suggestion and reflexes]

ANGYAL Lajos

[Schaffer summarises his final conclusions in the following sentences : 1. Intrahypnotic contractures are brain reflexes, but they can be influenced associatively. 2. The extent of a negative hallucination does not remain confined to the corresponding sensory cortical area, but spreads over the whole of the same hemisphere, with varying degrees of intensity. 3. Hysterical stigmata (deafness, blindness, anaesthesia, etc.) are not caused by dynamic damage to the corresponding central sensory areas, but are a disturbance (delusion ?) of the associative mechanism. ]

[Alzheimer's disease-like fibril lesion in circumscribed brain atrophy]

TARISKA István

[The author discusses the pathophysiological and histopathological differential diagnosis of Pick's disease and Alzheimer's disease. He describes a case with a slow progression over 6 years, first classified as Pick's disease on the basis of moral personality changes, spontaneity, vocabulary loss and lack of disease insight, and later as Alzheimer's disease on the basis of dementia, mild aphasia and motor dysfunction. Asymmetric and eunomic cortical atrophy of the brain, as well as sparing of the projection areolae, the high number of AFEs in the atrophied cortex and the integrity of the fronto-pontine pathway were considered from the perspective of the possibility of Alzheimer's disease. Histochemical examination of AFE did not allow him to reach a definite conclusion. Although the author considers Pick's disease and Alzheimer's disease to be independent nosological entities, he rarely considers their symptomatic confusion to be possible.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias

BALÁZS Nóra , BERECZKI Dániel, KOVÁCS Tibor

In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

[What has Go to do with making clinical decisions? One of the greatest intellectual challenges of bedside medicine is making decisions under uncertainty. Besides the psychological traps of traditionally intuitive and heuristic medical decision making, lack of information, scarce resources and characteristics of doctor-patient relationship contribute equally to this uncertainty. Formal, mathematical model based analysis of decisions used widely in developing clinical guidelines and in health technology assessment provides a good tool in theoretical terms to avoid pitfalls of intuitive decision making. Nevertheless it can be hardly used in individual situations and most physicians dislike it as well. This method, however, has its own limitations, especially while tailoring individual decisions, under inclusion of potential lack of input data used for calculations, or its large imprecision, and the low capability of the current mathematical models to represent the full complexity and variability of processes in complex systems. Nevertheless, clinical decision support systems can be helpful in the individual decision making of physicians if they are well integrated in the health information systems, and do not break down the physicians’ autonomy of making decisions. Classical decision support systems are knowledge based and rely on system of rules and problem specific algorithms. They are utilized widely from health administration to image processing. The current information revolution created the so-called artificial intelligence by machine learning methods, i.e. machines can learn indeed. This new generation of artificial intelligence is not based on particular system of rules but on neuronal networks teaching themselves by huge databases and general learning algorithms. This type of artificial intelligence outperforms humans already in certain fields like chess, Go, or aerial combat. Its development is full of challenges and threats, while it presents a technological breakthrough, which cannot be stopped and will transform our world. Its development and application has already started also in the healthcare. Health professionals must participate in this development to steer it into the right direction. Lee Sedol, 18-times Go world champion retired three years after his historical defeat from AlphaGo artificial intelligence, be­cause “Even if I become the No. 1, there is an entity that cannot be defeated”. It is our great luck that we do not need to compete or defeat it, we must ensure instead that it would be safe and trustworthy, and in collaboration with humans this entity would make healthcare more effective and efficient. ]

[In the healthcare system operating theatres have to put great emphasis on quality work, patient safety and efficiency as well, and to achieve this, optimal utilization of theatres is extremely important. The results of researches in this topic in Hungarian and international literature draw attention to a lot of aspects. The study of perioperative periods, and the evaluation of the analysed processes show that theatres could be operated more effectively. As a result of this, more operations could be carried out and waiting time would also reduce. In order to increase the efficiency of the processes, APNs can play a prominent role at several points. According to the experience, the number of people using health care and the number of people waiting for surgery is increasing, which is further increased by the development of the ongoing SARS-CoV-2 (COVID-19) epidemic. Thereby, patients are not satisfied with the service. The work of APNs would also help increasing the contentment of patients during the operation procedures. Taking advantage of the multifunctional role of the nurse due to her knowledge and training, she actively participates in the operation, in the smooth running of the scheduled daily surgical program and contributes to the reduction of the number of missed, planned surgeries.]
