Use of mexiletine in therapy-refractory recurrent ventricular tachycardia storm.

Electrical storm due to recurrent ventricular tachycardias (VTs) is a life-threatening arrhythmic emergency. The authors present a case report of a 69-year-old male patient with VT storm of non-ischemic etiology. Despite optimal medical treatment escalated by amiodarone antiarrhythmic drug therapy, the patient experienced multiple implantable cardioverter defibrillator (ICD) shocks. An electrophysiological study revealed an epicardial substrate; however, considering the patient's extreme obesity and active anticoagulant effect, catheter ablation was deemed to be unfeasible. Subsequently, mexiletine was added to the patient's drug regimen, resulting in successful control of arrhythmias during the following 6 months. Although the most recent European guidelines for the management of patients with ventricular arrhythmias mention mexiletine only for the treatment of LQT3 patients, its use for treatment-refractory VT storm seems to also be an important indication area.

Low socioeconomic position is a risk factor for delay to treatment and mortality of testicular cancer patients in Hungary, a prospective study.

BACKGROUND: In Hungary, the mortality rate for testicular germ cell cancer (TGCC) is 0,9/100000 which is significantly higher than the EU average. We prospectively evaluated the effect of socioeconomic position on patient delay and therapy outcomes. METHODS: Questionnaires on subjective social status (MacArthur Subjective Status Scale), objective socioeconomic position (wealth, education, and housing data), and on patient's delay were completed by newly diagnosed TGCC patients. RESULTS: Patients belonged to a relatively high socioeconomic class, a university degree was double the Hungarian average, Cancer-specific mortality in the highest social quartile was 1.56% while in the lowest social quartile 13.09% (p = 0.02). In terms of patient delay, 57.2% of deceased patients waited more than a year before seeking help, while this number for the surviving patients was 8.0% (p = 0.0000). Longer patient delay was associated with a more advanced stage in non-seminoma but not in seminoma, the correlation coefficient for non-seminoma was 0.321 (p < 0.001). For patient delay, the most important variables were the mother's and patient's education levels (r = - 0.21, p = 0.0003, and r = - 0.20, p = 0.0005), respectively. Since the patient delay was correlated with the social quartile and resulted in a more advanced stage in non-seminoma, the lower social quartile resulted in higher mortality in non-seminoma patients (p = 0.005) but not in seminoma patients (p = 0.36) where the patient delay was not associated with a more advanced stage. CONCLUSIONS: Based on our result, we conclude that to improve survival, we should promote testicular cancer awareness, especially among the most deprived populations, and their health care providers.

Quality expectations in endoscopy ­ Hungarian guideline / Az endoszkópia minoségi követelményei

Nowadays, endoscopy is the cornerstone in the diagnosis and therapy of gastrointestinal diseases. Good quality endoscopy can improve outcome of the disease and patients experience. International endoscopy societies prioritized efforts improving quality of endoscopy. The highest level of patient care can be provided through continuous assessment and improvement of relevant quality indicators. The comparison of these evidence based performance measures between endoscopists and endoscopy providers allow the objective evaluation of the service. Furthermore, from the point of view of patient safety and cost effectiveness the health care provider should know the minimum standards and target goals, as well, to make grounded decisions about fields of necessary changes and improvements. The authors based on European guidelines worked out this comprehensive auditable Hungarian system of performance measures in the fields of upper endoscopy, lower endoscopy, pancreatobiliary endoscopy, capsule endoscopy, enteroscopy and general endoscopy service. Due to commonality all domains were counted similarly (1­8) in different endoscopic procedures. The general endoscopy service is an exception with 9 domains and 30 quality parameters. The outstanding importance of colorectal cancer screening required involving this topic into this guideline with separate structure, as well as the basics of bowel preparation.

Using cannabis in oncology: facts and myths / Kannabisz használata az onkológiában: tények és tévhitek

Cannabis belongs to the highly prominent soft drugs; after coffee, tobacco and alcohol, it is considered to be the fourth most consumed psychoactive substance. The two most common cannabinoids are the strictly regulated psychotropic delta-9-tetrahydrocannabinol and the dietary supplement cannabidiol, which is non-psychoactive, only subject to reporting obligation and accessible in Hungary since 2004. In relation to the application of medical cannabis, especially in oncological indications, many misconceptions have arisen. In our review, we summarize the history of cannabis, the mechanism of action, the current evidences for application in oncological indications, the legal regulations, and highlight the potential concerns regarding cannabis administration.

Predictive Markers of First Line Pazopanib Treatment in Kidney Cancer.

Real-world evidence from clinical practices is fundamental for understanding the efficacy and tolerability of medicinal products. Patients with renal cell cancer were studied to gain data not represented by analyses conducted on highly selected patients participating in clinical trials. Our goal was to retrospectively collect data from patients with advanced renal tumours treated with pazopanib (PZ) to investigate the efficacy, frequency of side effects, and searching for predictive markers. Eighty-one patients who had received PZ therapy as first-line treatment were retrospectively evaluated. Overall survival (OS), progression-free survival (PFS) were assessed as endpoints. Median PFS and OS were 11.8 months (95% CI: 8.8-22.4); and 30.2 months (95% CI: 20.3-41.7) respectively. Severe side effects were only encountered in 11 (14%) patients. The presence of liver metastasis shortened the median PFS (5.5 vs. 14.8 months, p = 0.003). Median PFS for patients with or without side effects was 25.6 vs. 7.3 months, respectively (p = 0.0001). Patients younger than 65 years had a median OS of 41.7 months vs. 25.2 months for those over 65 years of age (p = 0.008). According to our results absence of liver metastases, younger age (<65 years) and presence of side effects proved to be independent predictive markers of better PFS and OS.

[Potential relevance of microRNAs in the diagnostics of inflammatory bowel diseases]. / A mikro-RNS-ek szerepe a gyulladásos bélbetegségek diagnosztikájában.

Inflammatory bowel diseases are chronic inflammatory disorders characterized by relapses and remissions. Several factors have been suggested to participate in their development, although their detailed pathogenesis still remains largely unknown. MicroRNAs are single strained, non-coding RNAs, consisting of 18-25 nucleotides that regulate gene expression at the posttranscriptional level. Aberrant expression of microRNAs has been found in several malignant tumors. Recently the role of microRNAs in the pathogenesis of inflammatory-autoimmune disorders (such as inflammatory bowel disease) is being intensively investigated. Beside their pathogenic roles, microRNAs can also be exploited as diagnostic markers, especially in cases where the interpretation of histological data is difficult. In this review the authors discuss recent findings in the field of microRNAs in the diagnosis and pathogenesis of inflammatory bowel diseases.
