[Holistic approach to cardiovascular prevention]

VÁLYI Péter

[Cardiovascular diseases, primarily the organic manifestations of atherosclerosis, such as coronary artery disease, ischaemic stroke, and peripheral arterial diseases, represent the largest healthcare problem in the developed countries, since the mortality, disability, and need for hospitalisation caused by them constitute a bigger burden than that caused by all other diseases combined. A modern, holistic approach to cardiovascular prevention should consider the complete cardiovascular continuum, including genetic predisposition, social-economicalcultural background, environmental factors, the integrated effect of atherosclerotic risk factors, the inhibition of progression of functional and morphologic damages that have already developed, and, if possible, the promotion of regression. Besides targeting the individual, prevention at the public and social level is also important.]

[Modern surgical treatment of lung cancer]

AGÓCS László

[Lung cancer is one of the most malignant human cancers because of its high incidence and high mortality rate. The 5-year relative survival rate for lung cancer at the initial diagnosis is 5-15%. Stage I or stage II non-small cell lung cancer (NSCLC) are considered early stage disease. Unfortunately, these two stages combined account for only 25 to 30% of tumours at the initial detection. At present, surgical resection remains the recommended treatment for patients with stage I and II NSCLC. Despite negative preoperative staging studies including mediastinoscopy, as many as one fourth of the patients will be found at surgery to have an occult N2 or one nodal station positive metastatic – stage IIIA – disease. Multimodality therapy is preferred for all subsets of stage IIIA patients. In stage IIIB and IV, surgical resection is possible and indicated only in selected cases, including Pancoast tumours, T4N0,1M0 tumours, the presence of satellite nodules in the same lobe, and certain solitary metastases. Patients with clinical stage T1-2 N0 small cell lung cancer (SCLC) may benefit from surgery for confirmation of diagnosis and improved local control when combined with chemotherapy. The mortality and morbidity rates of surgery in the treatment of lung cancer are reasonably low.]

[The aims and latest results of clinical toxicological analysis]

RÓNA Kálmán

[Almost 80 percent of poison-related deaths are caused by drugs. The overwhelming majority of today's clinical toxicological work is comprised of cases of toxic level drug overdose, drug mixups, adverse effects during therapeutic drug administration, as well as intoxication from drug abuse. A prerequisite of adequate therapy of intoxication is the qualitative and quantitative determination of the compounds causing it. The two elements of systematic toxicological analysis are the screening test and the confirmatory test. The review touches on the toxicologic use of the hyphenated chromatographic-spectroscopic instruments and on the alternative biological matrices. It is known that the effects and toxic side-effects of many drugs show substantial interindividual differences even in the same doses. One of the possible causes of this phenomenon is a genetically determined polymorphic drug metabolism. Some pharmacogenetically determined anomalies in drug administration, particularly enzyme inhibition and induction, are of clinical toxicological importance.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

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.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.

[Radiological response evaluation of targeted therapy]

KALINA Ildikó, OSZLÁNSZKY György

[The objective assessment of the changes in the tumor burden along with cancer therapy has essential importance. Recently, the quantitative evaluation of the radiological tumor response was undergone several changes. For conventional chemotherapy of solid tumors the standard procedure has been RECIST since 2000. The targeted therapies trigger other pathophysiological changes in the cells than the cytotoxic agents, accordingly the morphological changes show a new picture. Therefore the targeted therapies require a new evaluation system, that takes into consideration not only the tumor size, but other changes as well, the changes of attenuation that corresponds with the proportion of the viable cells. In case of the targeted therapies in substantial clinical was experienced even without signifi cant morphological changes in the tumour size. As a consequence, the traditional, size-based criteria system can underestimate the effi ciency of the new types of treatments. To eliminate this problem new evaluation systems were created taking the tumortypes and treatment protocolls into consideration. The estimation of the early tumor response to targeted therapy also has high importance. In assessment of the response functional imaging methods are used more frequently. The role of PET has already been defi ned in numerous tumortypes, however the determination of the position of some promising functional examinations still require further studies.]

[Treatment of hepatocellular carcinoma - today]

VÉGH Éva, DEMETER Gyula, BODOKY György

[The hepatocellular carcinoma (HCC) is one of the main causes of cancer-related death globally, and at the same time, it is the main event leading to death in cirrhotic patients. In the etiology of HCC, the non-alcoholic liver disease may be an important cause besides the viral cirrhosis. The HCC’s staging systems (Child-Pugh scores, Cancer of the Liver Italian Programme/CLIP, Barcelona Clinic Liver Cancer/ BCLC) play an important role in predicting the prognosis and determining the appropriate therapy. In Europe, the treatment strategy is based on the BCLC staging system. Screening of cirrhotic patient is also important because curative therapy is available only for the early-stage HCC. Several therapeutic options exist in the intermediate stage disease; among them the radiofrequency ablation (RFA), the transarterial chemoembolization (TACE) and the percutan ethanol injection (PEI) are most important. For the advanced disease, the only approved systemic therapy is sorafenib, which has been well-tolerated and yielded a substantially relative improvement in overall survival. For patient in end-stage disease with impaired liver function or a poor performance status, only supportive care is recommended.]

[The role of zonisamide in the treatment of women with epilepsy]

JUHOS Vera

[The antiepileptic drugs can effect fertility, development of gynecological diseases and occurence of sexual problems. They can cause a number of “cosmetic” problem and also influence the selection of safe contraceptive method. Many antiepileptic drugs can cause congenital malformations or affect the new-born child’s psychomotor and cognitive development, therefore during pregnancy should be treated with extreme caution in women with epilepsy. Most types of epilepsies accompany the patient through their whole life. Women spend almost the third of their lives after menopause and - due to the formation of associated diseases as well - this period is also special. According to the 2013 recommendation of International League Epilepsy (ILAE), zonisamide is one of the first-line antiepileptic drugs in focal epilepsy. In my review I discuss women’s epilepsy in the viewpoint of the application of zonisamid. ]
