[Despite decades of smoking cessation programs, and lung cancer screening programs, mortality due to bronchial cancer leads the mortality statistics among cancer deaths worldwide. Platinum-based chemotherapy has not fundamentally altered the effectiveness of treating non-small cell lung cancer (NSCLC). One of the newest approaches to the use of immunotherapeutic treatments in recent years is the so-called. use of immune checkpoint blocking agents. PD-1 and PD-L1 blockers of this type have been subjected to a large number of clinical trials in lung cancer and were reported by the tumor III.b / IV. stage. Last year, in 2018, we again came up with a milestone in the treatment of lung cancer immuno-oncology, as compared to the previous stage, III.a / III.b Durvalumab con­solidation therapy for non-small cell lung cancer after inoperative, non-chemo-radiotherapy phase I, is based on the results of the PACIFIC clinical trial. PACIFIC was a triple-phase, randomized, double-blind, placebo-controlled, multicentre study to evaluate the efficacy and safety of durvalumab consolidation therapy, irresistible, III. patients with non-small cell lung carcinoma who have not progressed after platinum-based chemo-radiotherapy. The PD-L1 expression level of the tumor was not an admission criterion. In the study, 713 patients were randomized to durvalumab and placebo for 2:1, progression-free survival (PFS) and over­all survival (OS) as their primary endpoint. Summarizing the results of the study, durvalumab provided significant benefit to patients at both endpoints. PFS and OS values were also significantly longer for durvalumab than placebo, and the safety profile of durvalumab was consistent with previous PD-1, PD-L1 inhibition tests.]

[Rifaximin-α: More than antibiotic ]

TALLER András

[Antibiotic therapy might alter gut microbiome. The consequence of that is dysbiosis with or without immediate overt clinical manifestation. The beneficial effect of rifaximin, a non-absorbable broad spectrum antibiotic, in gastrointestinal and hepatic disorders is known for a long time. According to recent data rifaximin has not only antibiotic but also anti-inflammatory and, within antibiotics, a unique special eubiotic effect as well. It modulates the gut microbiome, restores eubiosis through increasing beneficial species’ count while not disturbing diversity.]

[Physical inactivity and activity. Damage and benefit]

KÉKES Ede, APOR Péter

[Authors address the issue of inadequate physical activity worldwide and analyze their relationship with cardiovascular diseases and total mortality. In the inactivity "world map" it can be seen that in economically developed countries it is very common but other ethnic and regional factors also play a role and it is significantly more frequent at women. In our country this phenomenon due to combination of advanced civilization and computerization is also frequent. From 2000 to 2015, the trend of the presence of physical inactivity (FI) in the high income populations is steadily rising. Convincing evidence suggests that FI increases the risk of many common, serious diseases, including ischaemic heart disease, type 2 diabetes, breast cancer and colon carcinoma, and reduces the life expectancy. For these four diaseses, the incidence of FI occurs in about 1/3 of cases and 35% of total mortality. Its health value (PAF) ranges from 10 to 18%. Low (non-regular) exercise increases the risk of hypertension with or without family history. In subjects with moderate and intensive levels of physical activity (FA), there is a significantly lower mortality rate and the rate of occurrence of major cardiovasculars (CV) diseases compared to those with lower grade FA. Behind the positive effect of physical activity there is a multiple and complicated mechanism that manifests itself in the vascular system, in the physiological adaptation of the heart and in other metabolic and cellular effects. ]

[Treating methods of obstructive sleep apnea syndrome and related difficulties in daily practice ]

MOLNÁR Márton, CSATLÓS Dalma, HARGITTAY Csenge, MOHOS András, TERRAY-HORVÁTH Attila, DOMBOVÁRI Magdolna

[Obstructive sleep apnea syndrome (OSAS) is the most common breathing disorder during sleep. Its incidence is between 2-4%, but in many cases, the disease is not recognized. It has many symptoms, but the most typical symptoms are loud snoring and daytime sleepiness. Treatment always consists of several elements depending on the patients’ specific needs. When deciding on which treatment to use efficiency and the patients’ compliance are the key factors. The necessity of the therapy can be determined by three criteria: clinical complaints (daytime discomfort), the severity of the breathing disorder and the accompanying cardiovascular diseases. Treating possibilities for the mild to moderate OSAS are lifestyle changes (losing weight, avoiding alcohol and sedative drugs), positional therapy, oral appliances, and varied surgical corrections. For patients with moderate to severe OSAS and mild OSAS with severe symptoms the first line therapy is continuous positive airway pressure. In addition to presenting new therapeutic options, the authors describe the role of the family physician in the care of apnea patients.]

[Our immune system fi ghts effectively against infections, but the same activity exists against invading cancer cells, as well. However, malignant tumors are able to escape from these mechanisms; therefore tumor cells become unrecognizable for the immune system. Immuno-oncology is a novel and innovative discipline, focusing on a long-term purpose: to enhance the immune-response against malignancies. The main goal is to stimulate the immune system to properly recognize and destroy malignant tumor cells. This approach is comprehensive, includes the initiation of antitumor immune-response and enhancing its controlling mechanisms, moreover, provides active, anti-tumor effector cells. Recent results of anticancer research highlighted a new era of oncology, which is based on targeted, personalized medicine over cytotoxic therapies, and mainly focusing on the rapidly evolving discipline of immuno-oncology.]

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.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]
