[Long-term central venous access devices in oncology]

PAJKOS Gábor

[Long-term central venous access devices are essential in the management of oncology patients, as they minimize the discomfort caused by frequent venipuncture and cannulation. Indications of application of central venous accesses, possibilities of implantations, immediate and long term complications, they prevention and obviation has been reported based on guidelines and relevant publications. Long term implantable central venous accesses handled by well-trained and exercised team, working with principles of maintenance, these manipulations are effective and safe, therefore suitable in oncological practice.]

[Defi ciency of DNA-repair]

KOPPER László

[The cell uses the DNA to keep those information, which are vital to function properly. It is essential to maintain the integrity of the DNA, the stability of the genome. Since DNA damages, caused by external or internal factors, are continuously produced, DNA-repair mechanisms should be ready to identify and eliminate the damages. Either the repair system is successful and the cell can continue its duty, or, if the damages are unrepaired, the programed cell death (apoptosis) is activated according to the rule, that it is prohibited to transfer genomic/epigenomic damages into the daughter cells. It is true that the severness of the damages are not the same. The most important is the identifi cation and repair of those damages which can make genomic instability increasing the risk of cancer development. This may happen when the repair system is insuffi cient, sometimes due to inherited mutations (e.g. BRCA1 mutations can increase the risk of breast cancer, ovarian cancer etc.). Among the damages the DNA double strand breaks are rather common, and also, that the breaks are intended to be repaired in most cases. However, if such repair fails, the cell, here the cancer cell, due to the overhelming damages will dye. This phenomenon is the synthetic lethality. An example: „cooperation” of inherited BRCA1 mutation and PARP-inhibition, can lead to clinical response using PARP inhibitors, as oliparib. New agents and clinical trials intend to take advantage from synthetic lethality.]

[Biopharmaceuticals]

LÉVAY György

[Biopharmaceuticals represent a new class of very effective medications in the management of debilitating and often life-threatening diseases but the costs of these therapies exceed the costs of regular therapies. Biological medicinal products (i.e. smaller proteins or monoclonal antibodies) are mostly complex macromolecules, produced by microbial or mammalian cell cultures in bioreactors through application of complex process technologies. After patent expiry, the production of compounds with comparable quality features and comparable clinical safety and effi cacy profi les become available, however, the complexity of the macromolecules means they are not equivalent in the sense of small molecule generics. Biologics that are similar to a given licensed reference compound and meet regulatory requirements within this context can be termed as biosimilars. The similarity of the two products must be appropriately proven during the products’ marketing-authorisation procedure. As more and more biosimilar compounds have been approved by regulatory authorities in the EU and US it is expected that these products will bring signifi cant healthcare savings and much greater patient access to these revolutionary therapeutics.]

[Chemotherapy of multiple myeloma]

MIKALA Gábor, CEGLÉDI Andrea, CSACSOVSZKI Ottó, SZEMLAKY Zsuzsanna, PETŐ Mónika

[Multiple myeloma is a multifaceted haematological disease, a plasma cell malignancy that may pose an oncological differential diagnostic challenge. The importance of this disease is emphasized by its incidence. Since there are multiple novel therapies available for myeloma patients, decade-long survival in not uncommon; therefore, myeloma patients provide a signifi cant part of the patients referred to hematological clinics. In this review, fi rst the novel diagnostic criteria are introduced, followed by the standard therapeutic approaches for transplant-eligible and ineligible patients. As the disease nearly always relapses, the later line therapies available in this malignancy are presented with a special emphasis on the Hungarian haematological practice.]

[Earlier and more efficiently: the role of deep brain stimulation for parkinson’s disease preserving the working capabilities]

DELI Gabriella, BALÁS István, KOMOLY Sámuel, DÓCZI Tamás, JANSZKY József, ASCHERMANN Zsuzsanna, NAGY Ferenc, BOSNYÁK Edit, KOVÁCS Norbert

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]

[The role of the microbiome in the etiology and treatment of neoplastic diseases]

SCHWAB Richárd, BACSUR Emese, TORDAI Attila, PETÁK István

[Experimental data on the role of the microbiome in the onset and progression of infl ammatory diseases and cancer have been accumulated for years. An important milestone in this respect was the discovery that APC mutant mice in sterile conditions do not develop colon cancer of the FAP type. The direct role of the Enterobacteriaceae and Fusobacteriaceae bacterial families were also shown in the pathomechanism of the same experimental model. The toxic effect of chemotherapy on the gut fl ora has been well documented, but it may very well be that this putative side effect is part of the effi cacy, primarily in the case of adjuvant chemotherapy. The fi rst reproducible methods of microbiome molecular diagnostics are already available today. In addition to standard large clinical studies, we can increasingly rely on evidence of molecular pathomechanism and „real-world” clinical experience in the clinical interpretation of the microbiome. The overview summarizes the results of the fi eld research and its translation possibilities in terms of routine clinical practice.]

[How to break sensitive news in the Ophthalmology, specifically at diabetic retinopathy ]

TÓTH Lívia, BÁLINT Zsófia, MÁTÉ Orsolya

[The aim of the study: To investigate the circumstances of breaking bad news by health care professionals and the conditions of communication at the Ophthalmology Clinic of the University of Pécs, among diabetic retinopathy patients. Material and method: Quantitative and cross-sectional examination, February-December 2018. Statistical methods: descriptive and mathematical statistics (χ2-test), SPSSv22, (p<0,05). Results: Most of the examined medical professionals working at the clinic (20 persons/90.90%) can’t be supported by a protocol for breaking bad news, however, the need for a protocol is formulated as more than half of the respondents (11 persons/59.09%). Conclusions: Health care professionals would need to develop a protocol to break bad news in health care institutions, also in the Clinic of Ophthalmology, furthermore, attention should be paid to improving the circumstances during providing information to patients.]

[Changes in the treatment of childhood asthma with inhalational steroids]

CSERHÁTI Endre

[Since about 30 years, inhalational steroids are the most important drugs in the treatment of persistent (chronic) asthma. According to the severity of the disease, small, medium and high doses of steroids should be given, often together with long lasting beta-agonists. In the last years the therapeutical advice was simplified as the cromolyns and the theophyllins were almost excluded. Leukotrien antagonists appeared either in combination or as monotherapy. Using conventional doses in inhalational steroid therapy there are hardly any side effects, but it is important to give the smallest possible effective dose while achieving maximum bioavailability. Patients all over the world - including Hungary - do not receive optimal antiasthmatic therapy or use drugs ideally, which is especially true to inhalational steroids, resulting in a treatment much less efficient than possible.]

[Accident prevention and first aid knowledge among kindergarten children’s parents]

BÁNFAI Bálint, RADNAI Balázs, MARTON József, PÉK Emese, DEUTSCH Krisztina, BETLEHEM József

[INTRODUCTION - Based on statistics, accidents from various mechanisms are among the most common causes of death all over the world. Children are mostly affected in this situations. Our aim was to examine the first aid and accident prevention knowledge and attitude of the parents. PATIENTS AND METHODS - In this study parents of 3-7 years old children were involved in six kindergarten located in Hungary. A self-fill-in questionnaire was used to collect data. In the investigation 307 parents (N=307) were included. Out of them 234 respondents filled out the questionnaire correctly. The statistical analysis was made with SPSS 20.0 statistical software. For analyses deescriptive statistics, Chisquare- test and ANOVA were used. RESULTS - Three-quarters of the children have suffered at least one accident earlier (74.3%). Most of the accidents occured at home (88.5%). 174 parents attended first aid course earlier (74.4%), the previous knowledge is based mainly on the driving license (81.6%). Based on the answers it is important to teach children first aid (70.5%) and prevention (89.7%) knowledge in the kindergarten. There were only 10 parents, who answered all the situation questions correctly (4.3%). Between the subjective judgment of the financial status and the correct answers we found a significant correlation (p=0.03). The previously accomplished first aid training (p<0.05) and the educational attainment (p=0,029) had a positive impact on the results. CONCLUSION - The level of first aid knowledge of parents is lower than expected. Participate in first aid courses the level of knowledge could increase. It would be important, because some of the accidents can be prevented by acquiring proper knowledge.]
