[Increasing evidence suggests an important role of gender in the incidence, progression and different therapeutic possibilities of several diseases. Recent data demonstrated gender associated differences in the development and progression of chronic renal diseases. Present work reviews sexual dimorphism in different chronic renal diseases, summarizes underlying pathophysiological processes and therapeutic possibilities focusing on the role of gender. New evidences may present the base of gender based therapies in the future.]

[THE METABOLIC SYNDROME CLINICAL APPEARANCE, DIAGNOSIS, PATHOMECHANISM]

KÉKES Ede, CZURIGA István

[The metabolic syndrome has gone by several names over the past two decades. The diagnostic criteria were proposed by the ATP III of NCEP in 2001 and were accepted by European Society of Cardiology and European Society of Hypertension in 2003. The criteria (abnormal waist rate, HDLcholesterol, triglyceride, blood pressure and fasting glucose) are listed and the presence of any three of these factors is considered sufficient for diagnosis. The prevalence of syndrome affects about a quarter of the Hungarian population with hypertension. The metabolic syndrome is associated with premature cardiovascular morbidity and mortality including an excess of sudden deaths. According to the recent literature data the main component of the syndrome, the obesity, especially with abdominal fat distribution is associated with hypertension, hyperinsulinemia and insulin resistance with related abnormalities of carbohydrate and lipid metabolism. The low HDL cholesterol, high triglyceride level and the small, dense LDL cholesterol particles are the parts of lipid component of syndrome. A variety of environmental (obesity, smoking, physical inactivity) and genetic factors (genetic mutations of lipoprotein lipase, hepatic lipase, CETP and PPA receptors) and the impaired FFA metabolism have all been related to lipid abnormalities. Sympathetic hyperfunction participates in the pathogenesis and complications of metabolic syndrome. Possible factors augmenting sympathetic activation include alterations of insulin, leptin, FFA, cytokines, sleep apnoe. Other important factors as the endocrin concept, the hypothalamus-hypophysis- adrenal axis, endothelial dysfunction are discussed. The impaired muscle insulin stimulated glycogen synthesis (FFA induced GLUT-4 inhibition) is the major cellular factor of insulin resistance. There is a continuous process from the insulin resistance state (with hyperinsulinemia) into the 2T diabetes mellitus (with hypoinsulinemia).]

[Legionellae are important causative agents of nosocomial and community acquired pneumonias, the prevalence varying between 2-30%. The number of verified infections are increasing from year to year, which may be the consequence of the more sensitive and commonly applied laboratorical methods or can be explained by the spread of non-natural living environments created by humans. The outcome of Legionella infections are strongly determined by the host immune system, the comorbidities, the time to the diagnosis made and the initiated treatment. This review focuses on the various clinical manifestations of the Legionella infections, and summarises the diagnostic criteria and therapeutic methods in practice.]

BONCZ Imre, SÁNDOR János, OLÁH András, BETLEHEM József, SEBESTYÉN Andor, KISBENEDEKNÉ Gulyás Kinga, DÓZSA Csaba

[INTRODUCTION - The aim of this study is to analyse the local inequalities in the access and utilization of special home nursing within Hungary focusing on the South-Transdanubian Region. DATA AND METHODS - In the first part of the study we compared the indicators of the access and utilizations of special home nursing at national and county level. In the second part of the analyses we made a detailed analyses of utilization data of home nursing in the three counties (Baranya, Somogy, Tolna) of the South- Transdanubian Region of Hungary. Data is derived from the financial database of the National Health Insurance Fund of Hungary for the period 1998-2002. RESULTS - The access of population to the special home nursing increased from 83,8% (1998) to 95,1% (2002). The utilization rate increased from 74,8% (1998) to 84,1% (2002). Within the South-Transdanubian Region we found significant local inequalities in the utilization of services (number of cases, number of visits), which were represented by the tools of geographical information system. CONCLUSIONS - There have been significant differences in the access and utilization of home nursing with remarkable within country inequalities.]

[Cerebrovascular diseases in patients with chronic kidney disease]

KISS István, NAGY Judit

[The reason of the unfavourable life expectancy of patients with chronic kidney disease (CKD) is not only the development of end-stage renal failure but the frequent appearance of cardiovascular diseases (CVD). Chronic kidney damage itself is a cardiovascular risk state and the occurrence of CVD/associated diseases is significantly higher in chronic kidney failure. Beside risk stratification and valid treatment of CVD (hypertension, diabetes mellitus, ischemic heart disease e.g.) we and the international nephrological community have left the cerebrovascular diseases of CKD patients out of consideration. However, up to 50% of patients suffering a stroke will die immediately, only 10% of stroke survivors can continue his/her profession, but the others will be permanently disabled. High blood pressure is a strong predictor of stroke and of other CVD in most of the patients. In stroke risk reduction it is particularly important to reach the target blood pressure values. The main object of the “Live under 140/90 mmHg” programme of the Hungarian Society of Hypertension is to familiarize with target blood pressure itself and how to reach target blood pressure. In 2010, prevention, early diagnosis and management of stroke are the most important challenges of this programme (The Brain Control Programme). We think it is advisable to prepare and publish a clinical practice guideline in collaboration with stroke societies which is similar to the guidelines of international societies and of the Hungarian Society of Stroke but specific for CKD patients. This guideline would help to give a uniform, up-to-date treatment for the cerebrovascular diseases of CKD patients.]

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.

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.

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.
