[INTRODUCTION - Carcinomatous meningitis is a serious complication of advanced stage solid tumours, which may become more common with improved survival. CASE REPORTS - A 53-year-old woman with a recent history of breast cancer (pT2pN2M0) had been treated by mastectomy and adjuvant chemotherapy and radiotherapy. She presented with weakness, diplopia and vertigo raising the possibility of vertebrobasilar ischaemia or an intracranial mass. In another patient, a 62-year-old man with hypertension, a stenotic common bile duct had been diagnosed when examined for abdominal complaints. When he presented with a high blood pressure value accompanied by intensive headache, vomiting and bilateral hearing loss, he was thought to have a hypertensive crisis. The rapidly progressive neurological symptoms and the history of breast cancer and findings suggesting pancreatic head tumour, respectively, led to the clinical diagnosis of carcinomatous meningitis in both cases, despite any evidence on CT scans or a negative MR scan, though of limited value, in the first case. This diagnosis was confirmed by the laboratory and cytological findings of the cerebrospinal fluid, and also by the post mortem examination, since both patients died within a month after the onset of the symptoms. The primary tumour in the second patient proved to be a widely metastasizing diffuse type gastric cancer. CONCLUSION - Carcinomatous meningitis has a varying but characteristic presentation which generally makes it easy to diagnose, but it can sometimes present differential diagnostic problems. What we can learn from these two cases may help in recognizing this complication.]

[NEW WAYS IN THE MANAGEMENT OF RHEUMATOID ARTHRITIS IN HUNGARY]

GERGELY Péter, POÓR Gyula

[Rheumatoid arthritis is an autoimmune rheumatic condition of unknown origin. Due to its high prevalence, incompletely solved therapy, significant impact on mortality and morbidity, and the psychological and economic burden it puts on the patient, family and society, rheumatoid arthritis has a major public health significance. Although its importance is still underestimated both by the public and the medical community, today an improving tendency can be observed. The past decade has seen important breakthroughs in terms of increased recognition of the significance of the disease, as well as in its pathogenesis, diagnosis and therapy. The introduction of new diagnostic and prognostic markers and early aggressive treatment, the establishment of early arthritis clinics, and, most importantly, the successful use of biological therapy have revolutionized the management of rheumatoid arthritis. The paper reviews the modern therapy of the disease, touching on the options available in Hungary.]

[Vaccines against COVID-19 pandemic]

FALUS András, SZEKANECZ Zoltán

[The rapidly spreading SARS-CoV2 respiratory virus has evoked an epidemic with serious aftermath around the world. In addition to the health effects, the global economic damage is actually unpredictable. At the same time, the pandemic has launched a series of unprecedented collaborative scientific research, including the development of vaccines. This study summarizes up-to-date information on vaccines, immune memory, and some emerging clinical effects.]

Neuroscience highlights: The mirror inside our brain

KRABÓTH Zoltán, KÁLMÁN Bernadette

Over the second half of the 19th century, numerous theories arose concerning mechanisms involved in understanding of action, imitative learning, language development and theory of mind. These explorations gained new momentum with the discovery of the so called “mirror neurons”. Rizzolatti’s work inspired large groups of scientists seeking explanation in a new and hitherto unexplored area of how we perceive and understand the actions and intentions of others, how we learn through imitation to help our own survival, and what mechanisms have helped us to develop a unique human trait, language. Numerous studies have addressed these questions over the years, gathering information about mirror neurons themselves, their subtypes, the different brain areas involved in the mirror neuron system, their role in the above mentioned mechanisms, and the varying consequences of their dysfunction in human life. In this short review, we summarize the most important theories and discoveries that argue for the existence of the mirror neuron system, and its essential function in normal human life or some pathological conditions.

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.

[Neurological aspects of the COVID-19 pandemic caused by the SARS-CoV-2 coronavirus]

BERECZKI Dániel, STANG Rita, BÖJTI Péter, KOVÁCS Tibor

[By the spring of 2020 the COVID-19 outbreak caused by the new SARS-CoV-2 coronavirus has become a pandemic, requiring fast and efficient reaction from societies and health care systems all over the world. Fever, coughing and dyspnea are considered the major signs of COVID-19. In addition to the involvement of the respiratory system, the infection may result in other symptoms and signs as well. Based on reports to date, neurological signs or symptoms appear in 30-50% of hospitalized COVID-19 patients, with higher incidence in those with more severe disease. Classical acute neurological syndromes have also been reported to associate with COVID-19. A drop in the volume of services for other acute diseases has been described in countries with healthcare systems focusing on COVID-19. During the COVID-19 epidemic it is also important to provide appropriate continuous care for those with chronic neurological disorders. It will be the task of the future to estimate the collateral damage caused by the COVID-19 epidemic on the outcome of other neurological disorders, and to screen for the possible late neurological complications of the SARS-CoV-2 coronavirus infection.]

[Paradigm shift in management of patients with vertigo and imbalance]

MIKE Andrea, TAMÁS T. László

[Dizziness is one of the most common causes of medical visits. Management of the dizzy patient may be challenging both for the general practitioner, in emergency departments, and special clinics, as behind a seemingly homogeneous clinical presentation several very different etiologies may occur. Research of the last two century enriched our knowledge about physiology and pathophysiology of the vestibular system. Much knowledge is now available about the labyrinth being able to sense head motions and gravity, processing of afferent vestibular stimuli, reflectory oculomotor and postural control, or recovery of the vestibular system. Based on scientific results new beside tests have been introduced including provocation maneuvers for detecting ectopic otoliths in different semicircular canals, head impulse test to examine function of the vestibulo-ocular reflex, and the HINTS+ battery for differentiation of peripheral or central origin of an acute vestibular syndrome. Technical innovations like videooculography and vestibular evoked myogenic potentials enable us to selectively and side-specifically examine the function of all six semicircular canals and two otolith organs. Pathomechanism of disorders with vertigo and dizziness became more clear resulting in the development or amendment of diagnostic criteria of several vestibular disorders including vestibular migraine, Menière’s disease, benign paroxysmal positional vertigo, persistent postural-perceptual dizziness, bilateral vestibulopathy. Broader knowledge about the pathomechanism promoted the development of new therapeutic methods like different repositioning maneuvers in benign paroxysmal positional vertigo, pharmaceutical therapies, vestibular rehabilitation, and psychotherapy. We aimed to summarize the novelties in the field of oto-neurology.]
