[EMT (Epithelial-Mesenchymal transition) – CSC (Cancer Stem Cells)]

KOPPER László

[The effi cacy of the antitumor therapy is usually limited due to the resistance against the chemotherapy. One of the most important reason of the secunder resistance is the intratumoral heterogeneity, which is the consequence of the variety tumor phenotypes in the same tumor. Such clonal heterogeneity develops during the tumor growth or tumor therapy. The cancer stem cells (CSC), according to the concept, can determine the progression of the tumor, including metastatization, which probably the major enemy for clinical oncology. This activity of CSC, in tumors with epithelial origin, is supported by a change from epithelial to mesenchymal phenotype (epithelial-mesenchymal transition); but not entirely. The CSC phenotype is very similar to characteristic of the normal stem cells, as resistance, self-renewal etc. The mechanisms of these concepts is known only partially, but the technical advances contribute to the identifi cation of key genetic and epigenetic regulatory pathways. If such improvement becomes real, we can be much ahead both with markers and therapeutic targets.]

[Therapy and examination of generalized anxiety disorder in general practitioner practice]

BECZE Ádám, HARGITTAY Csenge, KALABAY László, TORZSA Péter

[Anxiety disorders are the most common psychiatric conditions in primary care, but still the ratio of treated patients is low. Clinically significant anxiousness decreases work efficacy and quality of life, it can cause and often goes with somatic and other psychiatric comorbidities. Patients with anxiety disorders usually undergo many diagnostic tests and interventions turning out negative on all levels of the health system. The general practitioner has a significant role in diagnosing and assessing anxiety disorders, based on a focused history, tests for differential diagnosis and questionnaire screening tools. The generalised anxiety disorder (GAD) is highly prevalent in primary care, appr. 8- 10%, 2-4 times frequent in women. Treat - ment is complex, evidence-based methods are available as certain lifestyle modifications, psychotherapy and pharmacotherapy. A regular consultation with a psychiatrist colleague can improve the chronic care of patients with anxiety disorders.]

[MRI has a significant role in the diagnosis of multiple sclerosis. The newer and newer treatment options of the disease make it necessary to monitor the effectiveness of the therapy. Besides the clinical signs (clinical relapses and progression), the different MRI parameters can also reflect the disease activity. In our current article we summarize those MRI markers, which best predict the long-term disability, based on the international standards.]

[The paraclinical examinations, principally the MRI have an increasing significance in the diagnosis of multiple sclerosis. However, MRI markers also have a prominent role in monitoring of the disease-course and activity, and also in the planning of possible therapeutic changes. In accordance with previously published international guidelines, in this article we propose a protocol for the monitoring the treatment efficacy in multiple sclerosis. This could be the basis of a consensus based guideline to be implemented in Hungary.]

A case with angiographic demonstration of isolated anterior spinal artery occlusion

DOGAN Burcu Vasfiye, KARA Batuhan, SELCUK Hatem Hakan, DIRICAN Ceyhan Ayten, KOKSAL Ayhan

Anterior spinal artery syndrome (ASAS) is a rare syndrome which occurs due to thrombosis of anterior spinal artery (ASA) which supplies anterior two thirds of the spinal cord. A 27-year-old female patient was admitted to emergency clinic with sudden onset neck pain, sensory loss and weakness in proximal upper extremities which occurred at rest. Thrombophilia assessment tests were negative. Echocardiography was normal. Serum viral markers were negative. In cerebrospinal fluid (CSF) examination, cell count and biochemistry was normal, oligoclonal band was negative, viral markers for herpes simplex virus (HSV) type-1 and type-2, Brucella, Borrellia, Treponema pallidum, Tuberculosis were negative. Diffusion restriction which reveals acute ischemia was detected in Diffusion weighted MRI. Digital subtraction angiography (DSA) was performed. Medical treatment was 300mg/day acetilsalycilic acid. Patient was discharged from neurology clinics to receive rehabilitation against spasticity.

[Is the evolvement of schizophrenia preventable?]

SZENDI István

[Considering the developmental nature of the majority of mental disorders, these days prevention has increasingly come into the focus of psychiatry. Schizophrenia - one of the disorders that are most frequently associated with psychosis, one of the most serious psychiatric syndromes - is the leading cause of permanent disability of the young adult generation. A prodrome lasting for several years precedes the onset of the first psychotic episode, which offers an opportunity for preventive interventions. Currently, we have two strategies for the predicition of the outburst of psychotic disorders. The Ultrahigh-risk approach can predict the first psychotic episode regardless of diagnosis, while the Basic symptom strategy predicts the development of schizophrenia specifically. However, there is an inverse relationship between the sensitivity and the specificity of different predictive criteria, which raises clinical and ethical dilemmas for the doctors. The methods of repeated assessments of the help-seeking individuals’ clinical states with designation of syndrome stages, and multivariate analyses of emprirically derived markers have proven promising tools for establishing more balance between the sensitivity and specificity of predictive criteria. Interven­tions of the secondary prevention aim to decrease the morbidity of the underlying pathomechanisms, and to help individuals’ coping with alterations of their experiences. We can consider here the psychosocial interventions as evidence based choices, which we can combine with certain food supplements and well-chosen psychopharmacons de­pending on the clinical state. With our in­terventions, we can influence the process of the individual development with vulnerable basis and steer it toward resilience. ]

Validation of the Hungarian version of Carlson’s Work-Family Conflict Scale

ÁDÁM Szilvia, KONKOLY THEGE Barna

Background and purpose - Work-family conflict has been associated with adverse individual (e.g., cardiovascular diseases, anxiety disorders), organizational (e.g., absenteeism, lower productivity), and societal outcomes (e.g., increased use of healthcare services). However, lack of standardized measurement has hindered the comparison of data across various cultures. The purpose of this study was to develop the Hungarian version of Carlson et al.’s multidimensional Work-Family Conflict Scale and establish its reliability and validity. Methods - In a sample of 557 employees (145 men and 412 women), we conducted confirmatory factor analysis to investigate the factor structure and factorial invariance of the instrument across sex and data collection points and evaluated the tool's validity by assessing relationships between its dimensions and scales measuring general, marital, and job-related stress, depressive symptomatology, vital exhaustion, functional somatic symptoms, and social support. Results - Our results showed that a six-factor model, similarly to that of the original instrument, fit the data best. Internal consistency of the six dimensions and the whole instrument was adequate. Convergent and divergent validity of the instrument and discriminant validity of the dimensions were also supported by our data. Conclusions - This study provides empirical support for the validity and reliability of the Hungarian version of the multidimensional Work-Family Conflict Scale. Deployment of this measure may allow for the generation of data that can be compared to those obtained in different cultural settings with the same instrument and hence advance our understanding of cross-cultural aspects of work-family conflict.

[Fulvestrant: long-term survival and quality of life in a patient with hormone receptor-positive advanced breast cancer]

PINTÉR Tamás

[INTRODUCTION - There are lot of evidence showing the efficacy of fulvestrant therapy in HER-2 negative, HR-positive advanced metastatic breast cancer. CASE REPORT - A 75-year-old female had a mastectomy, followed by series of adjuvant and radiotherapy about 30 years ago. Later cutan metastases were removed several times. The endocrine therapy had to be stopped because of intolerance. An ER, PR positive, HER-2 negative cutan metastasis was resected 7 years ago for the last time. During regular checkup, 5 years ago pulmonary nodule and bone metastases were found, - PET-CT disclosed multiple metastatic lymph nodes as well. We started fulvestrant and bisphosphonate therapy. Thereafter, as imaging revealed, the malignant disease has stabilized, the patient has a good performance status, her musculo-skeletal pain has a presumably degenerative origin. DISCUSSION - Reported case corroborates the potential efficacy of fulvestrant and ibandronate in hormone sensitive breast cancer with good prognostic markers, even in the case of metastases in soft tissue and bone. This case supports the data, that in patients with not progressive bone metastases the frequency of administration of parenteral bisphosphonates may be reduced to every 3 months. Advanced metastatic breast cancer may be converted to a chronic disease in properly selected cases, and it could mean long-term survival with a good quality of life.]

[Relationship between adipokinome and lipid parameters in Hungarian obese patients]

LŐRINCZ Hajnalka

[Since the prevalence of obesity has been dramatically increasing worldwide, a better understanding of obesity-related comorbidities leading to carbohydrate and lipid metabolism disorders has become essential. As an active endocrine organ, white adipose tissue secretes adipokines with diverse biological functions. We have found strong correlations between serum chemerin level and atherogenic lipoprotein sub-fractions in obese non-diabetic patients. To better characterize obese patients with and without manifest insulin resistance, we plan to determine serum levels of novel adipokines (omentin-1, vaspin, visfatin, lipocalin-2 and plasminogen activator inhibitor-1) and various oxidative stress markers including paraoxonase-1 activity, tumor necrosis factor-alfa and interleukin-6 levels, as well as low- and high-density lipoprotein subfractions in them and compare their data with lean individuals. We plan to determine correlations between the levels of novel adipokines and oxidative stress markers and lipoprotein subfractions. Furthermore, based upon our previous observations, we plan to study the potential alterations in the adipokine profile and the ratios of lipoprotein subfractions during a 5-year follow-up in obese patients. Our expected results may help to characterize the involvement of the adipokine profile in the regulation of lipoprotein metabolism. Early screening and treatment of lipid abnormalities may help to reduce the risk of cardiovascular events in obesity. ]

[Biomarkers - today and tomorrow]

KOPPER László

[Biomarkers (tumor markers in oncology) are able to make exact, objective and reproducible distinction between two groups. Biomarkers can serve different purposes, as to estimate the patient’s survival without treatment (prognostic marker), to select those patients who would respond optimally to treatment (predictive marker), to follow the patient in order to detect of a relapse (monitoring marker), helping identifi cation the tumor-type (diagnostic marker). The main task for a biomarker is to find the best treatment with less toxicity. The main enemy of biomarkers is the heterogeneity of the tumor, the continuous change in its geno- and phenotype, which can explain the low sensitivity and specifi city. More attention should be given to standardization and validity. It is highly possible, that biomarker-panel as well as marker-based clinical trials will be used in the near future.]
