Clinical Neuroscience - 2014;67(03-04)

[Although Hans Selye is mostly known for his discovery & development of the stress concept, he also introduced the first physiologically sound, structure-activity classification of steroids that was also based on the chemical structure of steroids in 1943. He not only introduced the names of glucocorticoids & mineralocorticoids but discovered the anti- & pro-inflammatory properties, respectively, of these steroids in animal models. Furthermore, he not only described the first stress-induced gastric ulcers in rats (1936) & characterized the first human ‘stress ulcers’ during the air-raids in London during World War II (1943). Thus, Selye was a much more productive & creative scientist than it is generally considered.]

[Association of temporal lobe inflammatory leukoencephalopathy with two B cell malignancies]

GARZULY Ferenc, HAHN Katalin, IVÁNYI János László, KERESKAI László, GÁBOR Valéria, KOVÁCS G. Gábor, BUDKA Herbert, KÁLMÁN Bernadette

[Identification of etiological connections among virtually distinct diseases in a patient may be sometimes challenging. We report a unique case with two B cell malignancies and an inflammatory leukoencephalopathy. Three days prior to admission, the elderly male patient developed fatigue, headaches, recurrent vomiting, memory disturbances, depression and somnolence. Clinical, laboratory and imaging evaluations as well as post mortem histological studies were performed. Simultaneous presence of primary central nervous system B cell lymphoma, temporal lobe inflammatory leukoencephalopathy and multiple (smoldering) myeloma, was revealed by the detailed work up in the treatmentnaïve patient. Based on recent data from genomic studies, we propose that a sequential evolution of molecular pathology lead to the co-occurrence of multiple myeloma and primary central nervous system B cell lymphoma in this patient, and interpret the development of the temporal lobe leukoencephalopathy as a likely paraneoplastic complication of smoldering myeloma.]

[STRESS IN THE CLASSIFICATION OF PITUITARY TUMORS. FOCUS ON AGGRESSIVE PITUITARY ADENOMAS]

KOVÁCS Kálmán, ROTONDO Fabio, HORVÁTH Éva, SYRO V Luis

[After a brief summary of the stress concept and the contribution of Dr. Hans Selye, this publication focuses on the classification of pituitary neoplasms and the difficulties to provide conclusive information on the prognosis of various pituitary tumor types. The term “aggressive pituitary tumors” was introduced. These tumors have a rapid cell proliferation rate. At present, the assessment of Ki-67 nuclear labeling index appears to be the simplest and most reliable method to evaluate tumor cell multiplication. Further studies on pituitary tumor biomarkers are needed.]

[The effect of chronic stress on defense mechanisms chronic inflammation and carcinogenesis]

MOLNÁR Ildikó

[During stress, the activation of the hypothalamus- pituitary-adrenal axis and the sympathetic, sensory nervous system leads to an increased production of glucocorticoids, catecholamines and other active peptides. The specific receptors on immunocompetent and tissue cells for glucocorticoid, corticotropin-releasing hormone and histamine, substance-P, norepinephrine, calcitonin gene-related peptide can modify the cytokine production of macrophages, lymphocytes and tissue cells. Local hormonal effects have a role in the degranulation of mast cells and thus in histamine release and neurogenic inflammation. Long-term, chronic inflammations promote carcinogenesis, in which the tumourassociated macrophages have an important role. Carcinogenesis is associated with disturbed cooperation between the neuronal immune and endocrine systems.]

[A PSYCHIATRIST’S PERSPECTIVES ON STRESS, STEROIDS AND MENTAL ILLNESS]

DUNAI Magdolna

[The relationship between stress and mental illness has been extensively studied and there is a growing consensus that the occurrence of mental illness rather depends on a combination of factors than is caused by stressful external events. Significant hypothalamus pituitary adrenal axis abnormalities were observed among others in major depressive disorder and bipolar disorder. In both disorders, the extent of change in cortisol level was related to the severity of illness and to cognitive changes. Exogenous use of synthetic steroids also frequently resulted in severe psychiatric symptoms. In conclusion changes in the level of steroid hormones may cause impairments in the brain.]

[Neuroendocrine background of atherosclerosis and cardiovascular damages in durable stress]

MOLNÁR Ildikó

[Chronic stress is associated with increased levels of cortisol and catecholamines as well as with an enhanced activity of the sympathico-sensory nervous system. These neuroendocrine events influence both directly and indirectly the lipid and glucose metabolism as well as inflammatory immune reactions. Stress effects directly cause vascular damage and atherosclerosis via the renin-angiotensin system (RAS). Besides RAS, activities of monocytes/macrophages and the sympathico-sensory nervous system lead to local cardiovascular inflammation and cell hypertrophy. Transactivation between G-protein coupled adrenoceptors and tyrosine kinase receptors as well as the switching between β1- and β2- adrenergic receptors play an important role in the development of cardiac hypertrophy and heart failure. In all chronic neuroendocrine diseases that are associated with increased activity of the sympathetic nervous system, the development of cardiovascular damages needs to be considered.]

[Comparative analysis of job and life satisfaction among theatre nurses in Hungary and Germany]

MÁTÉ Szilvia, PHIL. TIGGES-LIMMER Katharina, PUSZTAFALVI Henriette

[The aim of the study: The objective of the study was to assess and compare job and life satisfaction affected by workplace problems, stress, rewards, success and social support. We analyzed the coping strategies applied by the employees to solves the above problems. Material and method: The anonymous data collection was carried out in October, 2015 by applying AVEM and an own-edited socio-demographic questionnaire among theatre nurses from Hungarian and German clinics. Results: The employees evaluated stressful situations and problems differently in the two groups examined. Job satisfaction was equally important for both groups, but it affected life satisfaction of the Hungarian employees to greater extent. The stress management of the Hungarian employees was more effective in spite of the fact that German nurses used more coping strategies. Social support had a positive effect on overcoming the workplace problems in both groups. Conclusions: Job satisfaction of the nurses has a beneficial effect on their life satisfaction. The ability to divide work and private life and stress management are different among the nurses. Job satisfaction can be improved by workplace health promotion programs.]

[Applying musical tools in healing children]

KOLLÁR János

[The aim of the study is drawing the attention to the possibilities of applying musical tools in healing children. After doing research in main medical databases (PubMed, Web of Science, Medline) some research works were discovered and harmonized in which the researchers give proof of the effectiveness of music therapies implemented in therapeutic circumstances and by proper experts on medical fields. The study focuses on the following topics: applying music for reducing stress caused by medical interventions and hospitalization, treating speech disturbances, improving communication and social abilities of autistic children, improving capabilities of people suffering from visual and hearing impairment, providing help during anaesthesia, stimulating different parts of the brain in children suffering from PDOC (Prolonged Disorder of Consciousness), improving capabilities of children living with disabilities and helping creating harmonic relationship between children, their parents and the healing staff. ]
