[The hydromorphone is a potent semisynthetic opioid agonist which is available in several forms including injection immediately release or retard tablets. Its analgesic efficacy surpasses morphine. The absorption of oral osmotic retard tablet is independent from food- or alcoholconsumption providing steady plasma concentration by once daily application. The clinical pharmacology of hydromorphone is summarized.]

[The glucagon-like peptide (GLP)-1 receptor agonists and somewhat later, the sodium-glucose cotransporter (SGLT) -2 inhibitors have brought new perspectives in the antihyperglycemic treatment of type 2 diabetes. The article overviews clinicopharmacologic characteristics of the GLP-1 receptor agonist group, their glycemic and non-glycemic effects, results of the cardiovascular endpoint studies as well as their place in the recent therapeutic guidelines. It is proven, that both glycemic and weight reducing effect is greater of the long-acting (non-prandial) coumpounds as compared to that of the short acting (prandial) derivates, further, that in studies with cardiovascular endpoints they reduced the relative risk of the composite endpoint of non-fatal myocardial infarct, non-fatal stroke and cardiovascular death. Due to the favolurable glycemic and non-glycemic properties their use is advised already in the early course of type 2 diabetes, as combination of the metformin therapy.]

[Metamizole in use for almost 100 years, is reviving in our days since it has proved its efficiency and gained popularity during the past years. By its special triple effect (analgesic, antipyretic and spasmolytic) it has a wide range of indications. Among the non-opioid analgesics it is one of the most powerful painkillers. Metamizole is a prodrug, since it transforms into active metabolites within the human body. Its action mechanism is complex, not completely understood so far. Contrasted to classic non-steroidal anti-inflammatory drugs, metamizole has low anti-inflammatory effect. Its severe, but very rare side effect – i.e. the agranulocytosis - hindered its administration for years and even today it is under intense discussions. Based on international studies, it proved to be a well tolerable, safe medication. Its side effect profile differs from non-steroidal anti-inflammatory drugs, thus in NSAID contraindications it provides an excellent alternative. Its good water solubility makes metamizole suitable for both oral and parenteral administration. For its efficiency and good safety profile, metamizole has been correctly reintroduced to the supply of over-the-counter painkillers in our country.]
Clinical Neuroscience
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.
