Acid Reflux Management with the RefluxStop Implant: A Prospective Multicenter Trial with 3-Year Outcomes.

Background: RefluxStop is a unique implant for laparoscopic treatment of gastroesophageal reflux disease (GERD). It restores normal function of the gastroesophageal junction without the unwanted effects of encircling the esophagus, circumventing adverse events (AEs) associated with conventional anti-reflux surgeries.

Methods: Three-year follow-up of 50 patients with chronic GERD treated by RefluxStop was achieved in a prospective, single-arm, multicentric clinical trial analyzing safety and effectiveness of the procedure.

Significance of preoperative blood tests in the prognosis of colorectal cancer: A prospective, multicenter study from Hungary.

Background: The focus of this study was to analyze the prognostic value of different combinations of inflammatory and coagulation factors using preoperative blood and to appraise the clinical importance of these biomarkers in colorectal cancer patients.

Methods: A prospective, multicenter study included patients undergoing radical colorectal surgery in three county hospitals. Inflammatory and coagulation markers were analyzed preoperatively.

Effect of E2 and long control region polymorphisms on disease severity in human papillomavirus type 11 mediated mucosal disease: Protein modelling and functional analysis.

Interaction of the long control region (LCR) and the E2 protein of HPV11s was studied by in silico modelling and in vitro functional analysis. Genomes of HPV11s from fifteen (six known and nine novel) patients (two solitary papillomas, eleven respiratory papillomatoses of different severity, one condyloma acuminatum and one cervical atypia) were sequenced; E2 polymorphisms were analysed in silico by protein modelling. E2 and LCR variants were cloned into pcDNA3.

Resolving Differential Diagnostic Problems in von Willebrand Disease, in Fibrinogen Disorders, in Prekallikrein Deficiency and in Hereditary Hemorrhagic Telangiectasia by Next-Generation Sequencing.

Diagnosis of rare bleeding disorders is challenging and there are several differential diagnostics issues. Next-generation sequencing (NGS) is a useful tool to overcome these problems. The aim of this study was to demonstrate the usefulness of molecular genetic investigations by summarizing the diagnostic work on cases with certain bleeding disorders.

Molecular Profiling of Merkel Cell Polyomavirus-Associated Merkel Cell Carcinoma and Cutaneous Melanoma.

Merkel cell carcinoma (MCC) is a rare, high-grade, aggressive cutaneous neuroendocrine malignancy most commonly associated with sun-exposed areas of older individuals. A relatively newly identified human virus, the Merkel cell polyomavirus (MCPyV) has been implicated in the pathogenesis of MCC. Our study aimed to examine nine MCC cases and randomly selected 60 melanoma cases to identify MCPyV status and to elucidate genetic differences between virus-positive and -negative cases.

Vaginal elasticity is significantly decreased in vaginal atrophy: a strain elastography study.

Objectives: Strain elastography is a novel method to assess the elasticity of tissues. We aimed to evaluate the value of vaginal strain elastography in women with vulvovaginal atrophy (VVA).

Methods: Women with or without VVA were enrolled in this prospective study.

Predictive value of bubble sign for tubal patency during office hysteroscopy.

Objective: Our purpose was to investigate the predictive value of visible air bubble sign for real tubal patency during hysteroscopic procedures.

Methods: In this cross-sectional study, clinical data of 61 infertile women who underwent diagnostic hysteroscopy and laparoscopy have been analysed.

Results: Mean age of patients was 33.

Non-active implantable device treating acid reflux with a new dynamic treatment approach: 1-year results : RefluxStop™ device; a new method in acid reflux surgery obtaining CE mark.

Background: RefluxStop™ is an implantable, non-active, single use device used in the laparoscopic treatment of GERD. RefluxStop™ aims to block the movement of the LES up into the thorax and keep the angle of His in its original, anatomically correct position. This new device restores normal anatomy, leaving the food passageway unaffected.

Novel coronavirus epidemic in the Hungarian population, a cross-sectional nationwide survey to support the exit policy in Hungary.

After months of restrictive containment efforts to fight the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) epidemic, European countries are planning to reopen. To support the process, we conducted a cross-sectional survey among the Hungarian population to estimate the prevalence of infectious cases and prior SARS-CoV-2 exposure. A representative sample (n = 17,787) for the Hungarian population of 14 years or older living in private households (n = 8,283,810) was selected.

Comparison of different lymph node staging systems in prognosis of gastric cancer: a bi-institutional study from Hungary.

Objective: The Union for International Cancer Control (UICC) Node (N) classification is the most common used staging method for the prognosis of gastric cancer. It demands adequate, at least 16 lymph nodes (LNs) to be dissected; therefore different staging systems were invented.

Methods: Between March 2005 and March 2010, 164 patients were evaluated at the Department of General Surgery in the Kenézy Gyula Hospital and at the Department of General, Thoracic and Vascular Surgery in the Kaposi Mór Hospital.

Gastric bleeding in a patient with rheumatoid arthritis complicated by immune thrombocytopenic purpura.

Rheumatoid arthritis, in common with other systemic autoimmune diseases, can involve several other organs presenting with complex immunological manifestations. Immune thrombocytopenic purpura caused by an autoimmune reaction against platelets is an infrequent haematological complications. A female patient with rheumatoid arthritis rapidly developed extremely severe immune thrombocytopenic purpura upon suspending oral corticosteroid therapy.

Palliative treatment of esophageal carcinoma with self-expanding plastic stents: a report on 69 cases.

Objectives: The use of self-expandable plastic stents has offered a reasonable alternative of self-expandable metal stents in palliative treatment of esophageal malignancies, in the recent years. Studies and clinical data on the use of self-expandable plastic stents in esophageal cancer are, however, available in a very limited number. Here, we present the results of our 3-year study designed to evaluate the efficacy of self-expandable plastic stents in palliation of advanced esophageal carcinoma.

Hungarian migraine epidemiology.

Objective: A population-based epidemiological survey of migraine without aura and migraine with aura completed by mailed questionnaire in Hungary. The diagnosis and classification of migraine was according to the criteria of the International Headache Society.

Methods: The validity of the self-administered headache questionnaire was evaluated by a neurologist using clinical interviews.
