[Necrotising sarcoid granulomatosis: imitator in the chest]

AGÓCS Ágnes, ZIBOTICS Hilda, GREXA Erzsébet

[INTRODUCTION - Both intra and extrapulmonary manifestation of necrotising sarcoid granulomatosis is very rare. It is characterised by variable pulmonary radiological picture, typical histology and benign clinical course CASE REPORT - A young male patient was admitted to our hospital due to a mass lesion in the right apex of the lung suspicious of tuberculosis discovered on plain chest X-ray. Antituberculotic therapy resulted no change of radiological picture. Cytological sample taken by ultrasound guided fine needle aspiration contained no tumor cells. Finally necrotising sarcoid granulomatosis was confirmed by histological examination of the mass removed by atypical surgical resection. CONCLUSION - Intrapulmonary necrotising sarcoid granulomatosis has a variable picture. It has no typical radiological pattern or localisation, therefore it is impossible to diagnose by X-ray morphology. Final diagnosis is based on histology.]

[Opsismodysplasia A report of two cases]


[INTRODUCTION - Opsismodysplasia is a rare, severe, neonatal dwarfism usually associated with fatal outcome in the first few years of life. Up to, 2003 about 15 cases have been reported. CASE REPORT - We describe two brothers six and four years old with opsismodysplasia, who presented to the paediatric orthopaedic clinic with the diagnosis of short stature and genu varum deformity. CONCLUSION - Paediatric specialists should be aware, that in rare instances, with improving medical care, they may see children with severe bone dysplasias which usually do not reach age in which paediatric orthopaedic services are required.]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]


[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: 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.

[Consensus statement of the Hungarian Clinical Neurogenic Society about the therapy of adult SMA patients]

BOCZÁN Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette, SZÉLL Márta, KARCAGI Veronika, ZÁDORI Dénes, MOLNÁR Mária Judit

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]

Possible genotype-phenotype correlations in Niemann-Pick type C patients and miglustat treatment

ÇAKAR Emel Nafiye, ÖNAL Hasan

Niemann-Pick type C is a rare lysosomal storage disease caused by impaired intracellular cholesterol transport. The autosomal recessive disease is caused by mutations in NPC1 or NPC2 genes. Clinical-laboratory features, genotype-phenotype correlation and miglustat treatment response of our patients diagnosed with early infantile Niemann-Pick type C were evaluated. In this article, four Niemann-Pick type C patients diagnosed in the early infantile period are presented. Common features of our patients were hepatomegaly, splenomegaly, cholestasis and retardation in motor development. Patients 1 and 2 are twins, with homozygous mutation c.2776G>A p.(Ala926Thr) in NPC1 gene and severe lung involvement. Lung involvement, which is mostly associated with NPC2 gene mutation in the literature, was severe in our patients and they died early. In patients 3 and 4, there were respectively c.2972del p.(Gln991Argfs*6) mutation in NPC1 gene and c.133C>T p.(Gln45*) homozygous mutation in NPC2 gene. In these two patients, improvement in neurological findings were observed with treatment of miglustat. In our twin patients, severe lung involvement was observed. Two of our four early infantile Niemann-Pick type C patients exhibited neurological gains with miglustat treatment.
