Abstract: It is internationally recognized that the best method for practicing general medical care is family medicine, based on the correct relationship between the physician and the patients/families, where the principles of disease prevention and patient care meet, and the cost-benefit rates are better. In Hungary, a major part of the health reform had been the advancement of a primary care system by the international standards of modern family medicine. The Scientific Association of the Hungarian General Practitioners (SAHGP), founded in 1967, has adviced – from its onset – to introduce a new, independent medical specialty named ‘general practice’ which was finally realised in 1974. That was followed, according to the Welfare Ministry Order No. 6/1993, by the specific training program for general practice which prescribed, also for the in-service GP-s, to complete an individual postgraduate training, to be ended by a state specialty exam in family practice, under conduction of the regional medical schools. Furthermore, for strengthening the primary healthcare, in 1998 the government established – uniquely in Europe – the National Institute of Primary Healthcare (NIPHC). So a unique task force has gained shape which included the academic sector, the professional NGO and the governmental background institution in order to manage: 1) human resource supply in PHC, 2) to implement statewide professional and public health goals as well as 3) to manage research and development projects. This paper takes a look back at the early events of this process as well as tries to offer an insight into the results and conclusions of the performed research projects, highlighting those which can be potentially usable in further professional development of the Hungarian PHC.

Abstract: Our goal was to report a 44-year-old woman with carotid body tumor, and to give a brief and comprehensive presentation about the disease and summarize its complex management. Carotid body tumor is a rare, mostly sporadic, benign head and neck mass originating from the glomus caroticum. It occurs mostly in middle-aged women as a slowly growing, semifix, painless neck mass. The diagnosis is based upon the physical examination (pulsatile mass, Fontaine-sign) and – as the gold standard – CT-angiography. It should be established that preoperative embolisation by digital substraction angiography plays a crucial role in the treatment of carotid body tumors that should be followed by surgical removal. In case of inoperable/irresecable and residual tumors, radiotherapy is the treatment option. The patient was treated in our department in April 2017. Orv Hetil. 2018; 159(36): 1487–1492.

Abstract: The present study aims at overviewing the different stages of the education of medical psychology in Hungary. In the perspective of the achievements of cognitive and affective neuroscience as well as developmental psychology, we intend to define the roots of doctor-patient relationship, certain determining factors of diagnosis forming and therapy efficiency as well as the essential components of empathy. We attest to the fact that the current psychosomatic medicine with its evidence-based achievements is a valid component and constitutive pillar of everyday medical care. The integrated university level instruction of medical psychology and behavioral sciences aims at consolidating this perspective. We also emphasize that the ill body hinders adequate psychological functioning and mental disorders provide risk factors concerning somatic illnesses. Through spreading health psychology perspective, we support the concept that in everyday medical care, health protection and the development of health conscious behavior relies on responsible, informed and committed decision-making patients as well as on similarly educated extended medical care teams.

Published: October 2018

Abstract: The occlusion of the internal carotid artery (ICA) frequently leads to stroke and develops most commonly as a consequence of embolism or atherosclerotic thrombosis. Following acute care, if the patient’s general condition makes it possible, the patient is usually emitted from the hospital or, if necessary, his treatment continues in the rehabilitation department. The occlusion is generally considered irreversible, but a regular duplex ultrasonographic (sometimes CT angiographic) check of the patient is required. According to recent literature, spontaneous recanalization of the ICA may occur occasionally. The authors demonstrated by evaluating a local case that ICA occlusion is not necessarily permanent: through a case of a 67-year-old man, who suffered a right ICA occlusion, subsequent ichaemic stroke, then spontaneous recanalization of the occlusion allowing a successful endarterectomy later on, they overview the literature and propose appropriate prospective examinations to track patents with similar conditions.

Abstract: Introduction: The Professional Quality of Life Scale, measuring the quality of professional life, has been developed to examine the positive and negative changes in the work of those who have undergone extremely stressful experiences. The quality of life of the personnel of palliative-hospice teams may be influenced physically as well as emotionally by their every-day experiences of suffering, death, dying and the patients’ traumas. Aim: The aim of the study was the examination of the psychometric features and factor structure of the Hungarian version of the Professional Quality of Life Scale questionnaire, which can measure compassion fatigue and satisfaction, secondary traumatisation and burnout. Our long-term objective is the development of formative and intervention strategies for hospice workers in order to increase their satisfaction, physical and mental well-being and their willingness to work in hospice. Method: The cross-sectional, questionnaire study was made with hospice workers. The questionnaires were available in an anonym, printed form. We used the Hungarian versions of the Shortened Maastricht Vital Exhaustion Questionnaire and of the Shortened Beck Depression Scale, of the CES-D Depression Scale and of the Shortened WHO General Well-Being Scale to validate. Statistical analysis: IBM SPSS 23.0© software was used for the analysis. To explore the factor structure of the measurement scale, explorative factor analysis was made (analysis of the main component, Varimax rotation); subsequently, 4 scales were prepared the Cronbach-alpha values of which were suitable for further examination. Results: 188 questionnaires were sent back (female 86.2%, male 13.8%); the majority work as nurses and in home hospice care (94 people). The inner consistency of the created 4 scales is acceptable according to the Cronbach-alpha values. The inner consistency of the questions regarding burnout is low. The correlation of our measurement scales with the standardised scales for outer validity has sufficient strength and direction. Conclusions: Our questionnaire can measure the phenomena under examination according to the expected values, with suitable consistency on the basis of the inner and outer indicators.

Abstract: Genome-wide association studies (GWAS) using population-based designs have identified many genetic loci, at which common variants can influence the risk of developing the sporadic colon cancers. These are single nucleotide polymorphisms (SNPs) located on different chromosomes, close to genes involved in cancer developing process, and the SNPs modify their functions, and as a consequence the cancer risk is increased. Our aim was to provide frequency distributions data of variable (risk) allele of six independent SNPs in patients with colorectal cancers and in control Hungarian population, predicting the increased risk effect of sequence variant of SNPs. We also investigated the frequency distribution of tumor localization between right or left half of large bowel as well as the RAS mutation status. 47 non-tumorous patients and 47 patients with colorectal cancer were given oral mucosa cells or blood samples for SNP analysis. After DNA isolation, an LC480 (Roche) type PCR instrument, asymmetric LATE PCR method and melting point analysis were used for detection of sequence variations, by the assistance of two SNP specific primers, unlabeled specific probe and intercalating fluorescent dye. Genomic frequency distribution of variable alleles of SNPs predisposed to tumor development have been investigated in colorectal cancer carrier patients and the results have been compared with the same allele frequency distribution data obtained from the non-tumorous control patients and from CEU population stored in SNPnexus data base. The homozygous risk alleles of SNPs showed a 1.5–2.3-time increase in colorectal cancer carrier patients then in control and CEU patients, but the heterozygous risk allele distribution was identical in tumorous and control population. The frequency distribution of homozygous risk alleles of six SNPs was also investigated in the same time and some patients. Among 47 patients with colorectal cancer, in 3 patients carrying 3 SNPs with homozygous risk alleles, in additional 5 tumor samples two and 24 samples contain only one SNP’s homozygous risk alleles, and in 15 patients, SNPs with homozygous risk alleles do not occur. In 47 control patients, only 3 samples contain two SNPs with homozygous risk alleles and 17 samples contain only one SNP with homozygous risk alleles. Significant differences of the tumorous and the control population can be seen detected. NRAS mutation was not found. Our results showed a real increased risk effect of several newly recognized low-penetrance colorectal cancer susceptibility genetic variants by influence of the regulation of neighboring genes, however, the degree of cancer risk is individual, and influenced by others environmental factors, such as dietary factors.

Abstract: Diabetes mellitus involves a group of chronic metabolic disorders with elevated blood glucose concentrations. Since this disease needs lifelong treatment and care, the medical and social aspects present major public health concerns and pose a global challenge for health care providers. The number of aged patients with degenerative diseases undergoing surgical procedures is continuously increasing, resulting in an overwhelming dominance of diabetes in the perioperative care. There is a particular need for an increased awareness of diabetic patients in cardiovascular units, where the incidence of this disease reaches as high as 30–40%. The main hallmarks of the pathologic metabolic milieu of diabetes are hyperglycaemia, insulin resistance and pathologic lipid metabolism. The biochemical, cellular and organ-level pathophysiological changes lead to endothelial dysfunction including a low-grade prothrombotic balance, inflammatory state and, as a consequence, impaired micro- and macrocirculation. Diabetes is also followed by platelet dysfunction resulting from intracellular hyperglycaemia, because thrombocytes have insulin-independent glucose transporters in their cell membrane. The levels of the coagulation factors of the plasma are increased, and these factors are also modified by oxidation and glycation. Diabetes mellitus is a prothrombotic condition resulting from direct and indirect tendencies of the endothelial platelet and the plasma coagulation factors. The basic “bench to clinical basics” knowledge of the endothelial dysfunction and prothrombotic balance in diabetes may contribute to the better understanding of the clinical focuses in the perioperative care of patients with diabetes mellitus.

Abstract: Introduction: Recently, tumor-infiltrating immune cells have been studied in various cancers. However, fewer studies address the role of peripheral immune cells in the pathogenesis of cancer. Aim: Our aim was to investigate whether the phagocytic activity of peripheral monocytes and neutrophil granulocytes is affected by the removal of tumor in advanced ovarian cancer. Method: We investigated peripheral blood samples from 12 patients with advanced stage of serous epithelial ovarian cancer – which were collected before the optimal tumor reduction surgery and on the 7th postoperative day – and from 8 healthy women. After separation of monocytes and neutrophils, the cells were incubated with opsonized fluorescein isothiocyanate-labeled zymosan A particles as the target of phagocytosis. By using fluorescence microscope we counted the number of particles phagocytized by the cells and calculated the phagocytic index. Statistical analysis of the data was performed using analysis of variances method. Results: Preoperative phagocytic indexes of monocytes and neutrophils from patients were significantly lower than phagocytic indexes of the corresponding cells from healthy women. The phagocytic function of monocytes and granulocytes isolated from postoperative samples of patients significantly increased compared to preoperative values and reached the phagocytic indexes of monocytes and neutrophils from healthy controls. Conclusion: Based on our results we assume that the tumor and/or its microenvironment in ovarian cancer may produce factors that can depress the phagocytic function of monocytes and granulocytes. Since the phagocytic indexes increased following the cytoreductive surgery, it can be assumed that after the removal of the tumor, the production of these factors is reduced or eliminated.

Abstract: The assessment of skeletal age is of utmost importance not only in the field of anthropology, forensic medicine, pediatrics, endocrinology but also in orthodontics and jaw orthopedics. Bone age refers to the individual’s biological development which can differ within a relatively wide range for the same chronological age. Therefore, accurate assessment of skeletal maturity and pubertal growth plays an important role in establishing a diagnosis for certain diseases. In addition, it is essential for proper timing and success of treatments in many cases. Currently, there are many methods available to determine skeletal age and pubertal growth spurt. During growth, bones undergo significant changes, the sequence of which is strongly determined. These changes can be measured by various methods including radiological examinations. More specifically, these classical methods are often based on the radiological evaluation of morphological changes in the hand bones and cervical vertebrae. Methods based on dental development also exist to assess the biologic maturity of an individual. However, thanks to three-dimensional imaging techniques and molecular diagnostic methods, even more accurate tests can be performed to determine biological maturity. These modern methods rely on the information obtained from the cone-beam computer tomograph records and on the measurements of biomarkers present in different circulatory or other body fluids. The purpose of this summary is to provide an overview of the various classical and modern methods for the assessment of skeletal age that could aid us in many fields of science.

Abstract: During assisted reproduction technologies, controlled hyperstimulation of the ovaries occurs. Ovarian hyperstimulation syndrome is an excessive overreaction of the ovaries complicating pharmacological ovulation induction. Rarely other causes, such as the mutation of the follicle-stimulating hormone receptor may also be in the background. Ovarian hyperstimulation syndrome is clinically characterized by a massive ovarian enlargement associated with an acute third-space fluid shift responsible for the development of ascites, and sometimes pleural or pericardial effusion. Associated arterial or venous thromboembolic symptoms are also common. Ovarian hyperstimulation syndrome is an iatrogenic and potentially life-threatening condition in the form of ischemic stroke or circulatory insufficiency of the limbs. Recently some new methods have been developed for the prevention of the disease. The syndrome affects young, healthy patients. It also has an important economic burden due to the absence from work, bed rest, or hospitalization and intensive medical management of more severe cases. Supportive therapy, anticoagulant prophylaxis and close monitoring are the main approach for the syndrome. However, hospitalization or intervention should not be delayed for patients with severe or critical conditions. Orv Hetil. 2018; 159(34): 1390–1398.
Az etopozid szervezeten belüli eloszlásában és metabolizmusában szerepet játszó epigenetikai hatások

Published: October 2018

Abstract: Etoposide is a topoisomerase II inhibitor antitumor agent which is widely used in the treatment of several hematologic malignancies and solid tumors. The therapeutic index of etoposide is quite high, thus its application causes several short-term and long-term side effects which can decrease the chance to cure patients. Drug dosing is based on body surface area calculation; recommendations for individual dosing do not exist yet. The biotransformation and transportation of etoposide are carried out by enzymes and transporters as reported in pharmacogenomic studies published in this area. Nowadays pharmacoepigenetics research has come to the fore. The authors wish to give an insight into the research of the epigenetical changes of the etoposide pathways, especially focusing on published findings on enzymes and transporters with pharmacokinetic relevance. In the future, epigenetical changes of the etoposide pathway might have a great role in diagnostics, prognostics and personalized medicine. Orv Hetil. 2018; 159(32): 1295–1302.

Abstract: The community of microorganisms in the intestine, namely gut microbiome lives in symbiosis with the host, contributing to its homeostasis and influencing it simultaneously. It can be suspected that gut microbiome plays a central role in the pathophysiology of intestinal and extraintestinal diseases: determining their development, progress and complications. Recently, intestinal microbiome has become a highlighted field of interest and important topic in research, especially in hepatology. It is in the focus of relevant research as the liver is the organ which meets nutrients, bacterial components, toxins and metabolites at first, as a filter. The evolvement of different liver diseases – just like alcoholic and non-alcoholic fatty liver disease, steatohepatitis, cirrhosis or hepatocellular carcinoma – correlates with the changed composition and activity of gut microbiome. Thus, it can be hypothesized that pre-, pro- and antibiotics could have an impact on the treatment of these diseases. In our review article, the relationship between intestinal flora and liver diseases with different etiologies as well as therapeutic possibilities are discussed. Orv Hetil. 2018; 159(36): 1465–1474.

Abstract: Introduction and aim: To determine whether the continuous use of gel-type denture adhesives influence the unstimulated whole saliva, the palatal and labial saliva flow rates, and to assess the possible changes of subjective orofacial sicca symptoms. Method: 28 maxillary complete denture wearing patients (average age: 70 ± 10 years) were investigated. A gel-type denture adhesive was administered to the patients for regular use during the 3 weeks of examination. A questionnaire of 16 questions was used to evaluate subjective orofacial sicca symptoms. Unstimulated whole saliva was determined by the spitting method, palatal and labial saliva flow rates were measured by the Periotron® device with filter paper discs at the initial, first, second and third weeks. Statistical analysis: The following tests were used: subjective values – χ2-test; flow rates – ANOVA, paired Student’s t-test. Results: According to the questionnaire, the ratio or severity of xerostomia did not change. A significant increase in the subjective feeling of “saliva thickness” could be detected (p = 0.027), but the other subjective parameters remained unchanged. Palatal saliva flow rates decreased significantly by week 3 (week 0: 4.21 ± 3.96 µl/cm2/min; week 3: 2.21 ± 2.30 µl/cm2/min; p = 0.024). On the other hand, there was no significant change in the unstimulated whole saliva (week 0: 0.37 ± 0.36 ml/min; week 3: 0.39 ± 0.35 ml/min) and labial saliva (week 0: 3.99 ± 3.75 µl/cm2/min; week 3: 2.58 ± 3.39 µl/cm2/min) flow rates. Conclusions: The regular use of denture adhesives did not influence xerostomia and the majority of subjective orofacial sicca symptoms, but may cause a subjective feeling of “increased saliva thickness” and reduce palatal minor salivary gland flow rates among complete maxillary denture wearers.
