Background: Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in the world affecting over 50% of the world's population. H. pylori is a grade I carcinogen, responsible for the development of 89 % of noncardia gastric cancers. In the present study we analyzed the data for H. pylori eradication treatments in Slovenia. Patients and methods: Slovenia is a part of the European Registry on Helicobacter pylori Management from the beginning...

BACKGROUND: There is an association of Gastroesophageal reflux disease (GERD) with chronic obstructive pulmonary disease (COPD). This study was designed to determine the frequency of GERD in COPD patients. METHODS: This descriptive, cross-sectional study was conducted in the Pulmonology Unit Ayub Teaching Hospital Abbottabad. Patients more than 40 years of age of both genders presenting with features of COPD such as cough and breathlessness for more than 6 months and confirmed by spirometry were included in the study...

BACKGROUND: Helicobacter pylori (H. pylori) infection causes various gastrointestinal diseases including gastric cancer. Hence, eradication of this infection could prevent these diseases. The most popular first-line treatment protocol to eradicate H. pylori is termed "triple therapy" and consists of a proton pump inhibitor (PPI), clarithromycin, and amoxicillin or metronidazole. However, the antibiotics used to treat H. pylori infection are hindered by the antibiotics-resistant bacteria and by their antimicrobial activity against intestinal bacteria, leading to side effects...

BACKGROUND: Acute tubulointerstitial nephritis (ATIN) has been increasingly recognized as an important manifestation of kidney injury associated with the use of immune checkpoint inhibitors (anti-PD-1 and anti-CTLA-4). While the exact pathophysiology remains unknown, corticosteroids are the mainstay of management. CASE PRESENTATION: We describe a 67-year-old man with stage IV non-small-cell lung cancer who developed kidney injury during treatment with the anti-PD-1 antibody nivolumab...

BACKGROUND: The association of long-term use of proton pump inhibitors (PPIs) with oesophageal adenocarcinoma has been poorly defined. Our aim was to assess the risk of oesophageal cancer assessing confounding by indication. METHODS: This population-based cohort study included all 796,492 adults exposed to maintenance therapy with PPIs in Sweden in 2005-2012. Standardised incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated to assess the risk of oesophageal adenocarcinoma (and squamous cell carcinoma as a comparison) among long-term PPI users relative to the corresponding background population...

AIM: Dysplastic FGPs (d-FGPs) typically arise in patients with familial adenomatous polyposis (FAP) but may occur in nonsyndromic patients. They rarely develop malignancy, but their significance is unclear, especially in nonsyndromic patients. APC/β-catenin alterations have been implicated in their pathogenesis, and β-catenin immunohistochemistry (IHC) may show nuclear positivity. METHODS AND RESULTS: We identified 124 FGPs with low-grade dysplasia (LGD) or high-grade dysplasia (HGD) or indefinite for dysplasia (IFD) from 66 patients (27 with FAP, 39 nonsyndromic)...

Hoarseness is a common presentation in primary care practices. Combined with other voice-related changes, it falls under the umbrella diagnosis of dysphonia. Hoarseness has a number of causes, ranging from simple inflammatory processes to less common psychiatric disorders to more serious systemic, neurologic, or cancerous conditions. Medication-induced hoarseness is common and should be considered. The initial evaluation begins with a targeted history and physical examination, while also looking for signs of potential systemic etiologies...

Background C-Met, which is frequently activated in multiple cancers, has been implicated in tumor formation, progression, metastasis, angiogenesis, and resistance to multiple therapies. MK-8033 is a small-molecule inhibitor of c-Met that binds preferentially to the activated conformation, and has demonstrated anti-tumor activity in preclinical models. This first-in-human trial was performed to establish the safety and maximum tolerated dose (MTD), as well as preliminary pharmacokinetics (PK) and clinical activity...

The main pharmacovigilance updates in 2017 are reviewed. Denosumab : rebound-associated multiple vertebral fractures after discontinuation. Canagliflozine: increased risk of foot/leg amputations. Biologic and targeted cancer therapies, direct-acting antivirals for chronic hepatitis C: risk of hepatitis B reactivation. Checkpoint inhibitors : immune-related adverse events and graft rejection. Fingolimod : rebound-associated reactivation of MS following withdrawal. Daclizumab: risk of severe liver injury leading to restricted use in MS patients...

RATIONALE: Clostridium difficile infection (CDI) is a symptomatic infection due to the spore-forming bacterium, C. difficile. Asymptomatic C. difficile colonization is the stage in absence of symptoms, with a prevalence of 1.4% to 21% on hospital admission. Proton-pump inhibitors (PPIs) was implicated as a novel potential contributor to CDI. PPIs injection could make asymptomatic C. difficile colonization progress to C. difficile associated diarrhea (CDAD). PATIENT CONCERNS: A postoperative colon cancer patient, who had been taking omeprazole for 4 years after operation, got asymptomatic C...

BACKGROUND: Helicobacter pylori (H pylori) is associated with peptic ulcer disease and gastric cancer. AIM: To test how various lengths of delays in H pylori eradication therapy influence the risk of recurrent peptic ulcer, ulcer adverse events and gastric cancer. METHODS: This population-based nationwide Swedish cohort study included 29,032 patients receiving H pylori eradication therapy after peptic ulcer disease in 2005-2013. Pre-defined time intervals between date of peptic ulcer diagnosis and date of eradication therapy were analysed in relation to study outcomes...

PURPOSE: Despite plausible mechanisms, the clinical significance of long-term proton pump inhibitor (PPI) use to colorectal cancer (CRC) remains unknown. The purpose of this study was to investigate the association between PPI use and CRC development. METHODS: We conducted a population-based prospective cohort study using the Korean nationwide claims database merged with national health examination data. The study cohort included a total of 451,284 participants who were tracked to identify cases of CRC since 2007...

BACKGROUND & AIMS: Endoscopic surveillance of patients with Barrett's esophagus (BE) is inefficient. Risk stratification of patients might improve the effectiveness of surveillance. We performed a systematic review and meta-analysis to identify factors associated with progression of BE without dysplasia or BE with low-grade dysplasia (LGD) to high-grade dysplasia or esophageal adenocarcinoma. METHODS: We performed a systematic search of databases through May 2016 to identify cohort studies of patients with baseline BE without dysplasia or BE with LGD that reported predictors of progression...

Background and Objectives: Clostridium Difficile is the most common cause of nosocomial infectious diarrhea. This study evaluates the prevalence and predictors of Clostridium Difficile infections in patients undergoing radical cystectomy with or without neoadjuvant chemotherapy. Methods: Retrospective chart review was performed of all patients undergoing cystectomy and urinary diversion at a single institution from 2011-2017. Infection was documented in all cases with testing for Clostridium Difficile polymerase chain reaction toxin B...
