Combined Cholecystoenteric Fistula and Choledocholithiasis: A Report of a Rare Case.

Cholecystoenteric fistulas are a rare complication of chronic gallstone disease. If not diagnosed on time, they can cause several complications such as gallstone ileus, gastric outlet obstruction (Bouveret syndrome), cholangitis, or liver abscess. We present a case of a patient with chronic calculous cholecystitis, who was admitted due to unspecific abdominal discomfort and impaired liver function with increased cholestatic liver enzymes.

A Case of a Successfully Treated Patient With a Delayed Diagnosis of Boerhaave's Syndrome and Severe Complications.

Boerhaave's syndrome is a rare critical condition manifesting as transmural esophageal rupture. It is usually associated with forceful emesis and increased intraesophageal pressure. Immediate aggressive surgical intervention is imperative in such cases.

A Late Native Oesophago-Pulmonary Fistula, Oesophageal Foreign Body and Chronic Lung Abscess After Retrosternal Colo-Oesophagoplasty.

The development of a late fistula between a native unremoved corrosively altered oesophagus and the right lung with subsequent chronic lung abscess formation 34 years after retrosternal colo-oesophagoplasty is an extremely rare complication. According to our review of the English-language literature, such a case has not been described so far. We present a 50-year-old man with complaints of dry cough, periodic epigastric postprandial pain, regurgitation of food and halitosis, which started about seven years ago.

An Inflammatory Fibroid Polyp of the Stomach.

An inflammatory fibroid polyp (Vaněk's polyp) is a rare, benign, mesenchymal polyp originating from the submucosa of the gastrointestinal tract. Symptoms are non-specific and depend on the tumor size and location. Despite their benign nature, these tumors can mimic other malignant conditions, making an accurate diagnosis crucial for appropriate management.

SPR and Double Resonance LPG Biosensors for BabA Antigen Detection.

Given the medical and social significance of infection, timely and reliable diagnosis of the disease is required. The traditional invasive and non-invasive conventional diagnostic techniques have several limitations. Recently, opportunities for new diagnostic methods have appeared based on the recent advance in the study of outer membrane proteins and their identified receptors.

Apolipoproteins as predictors of cardiovascular risk in patients with chronic pancreatitis.

Objective: Patients with pancreatic diseases are at increased risk of cardiovascular events. Investigating various apolipoprotein forms as important atherogenesis components may improve cardiovascular risk (CVR) prediction. This study aimed to investigate CVR factors in patients with chronic pancreatitis.

Improving dental epithelial junction on dental implants with bioengineered peptides.

The functionalization of titanium (Ti) and titanium alloys (Ti6Al4V) implant surfaces via material-specific peptides influence host/biomaterial interaction. The impact of using peptides as molecular linkers between cells and implant material to improve keratinocyte adhesion is reported. The metal binding peptides (MBP-1, MBP-2) SVSVGMKPSPRP and WDPPTLKRPVSP were selected via phage display and combined with laminin-5 or E-cadherin epithelial cell specific peptides (CSP-1, CSP-2) to engineer four metal-cell specific peptides (MCSPs).

A novel panel of clinically relevant miRNAs signature accurately differentiates oral cancer from normal mucosa.

Introduction: Although a considerable body of knowledge has been accumulated regarding the early diagnosis and treatment of oral squamous cell carcinoma (OSCC), its survival rates have not improved over the last decades. Thus, deciphering the molecular mechanisms governing oral cancer will support the development of even better diagnostic and therapeutic strategies. Previous studies have linked aberrantly expressed microRNAs (miRNAs) with the development of OSCC.

Randomized clinical trial: A double-blind, proof-of-concept, phase 2 study evaluating the efficacy and safety of vonoprazan 20 or 40 mg versus esomeprazole 40 mg in patients with symptomatic gastro-esophageal reflux disease and partial response to a healing dose of a proton-pump inhibitor.

Background: Proton-pump inhibitors (PPIs) are cornerstone treatments for gastro-esophageal reflux disease (GERD); however, evidence suggests that most patients exhibit partial response to PPIs, suggesting the need for novel therapies that can provide an improved and sustained increase in gastric pH.

Aims: This study aimed to determine the effect of vonoprazan, a novel, orally active small-molecule potassium-competitive acid blocker, versus esomeprazole, a PPI, in preventing heartburn symptoms over a 4-week treatment period in patients with GERD and a partial response to esomeprazole treatment.

Methods: This randomized, double-blind, proof-of-concept, phase 2 clinical trial was conducted between 2016 and 2018 at 39 sites across Europe and designed to evaluate the efficacy and safety of vonoprazan 20 mg once daily (q.

Salivary miR-30c-5p as Potential Biomarker for Detection of Oral Squamous Cell Carcinoma.

The levels of different classes of extracellular RNAs (exRNAs) remain stable in bodily fluids. The detection of either enriched or depleted specific subsets of salivary microRNAs (miRNAs) has the potential to serve as a non-invasive approach for biomarker development. Thus, salivary miRNAs have emerged as a promising molecular tool for early diagnosis and screening of oral squamous cell carcinoma (OSCC).

Alternative RNA Splicing-The Trojan Horse of Cancer Cells in Chemotherapy.

Almost all transcribed human genes undergo alternative RNA splicing, which increases the diversity of the coding and non-coding cellular landscape. The resultant gene products might have distinctly different and, in some cases, even opposite functions. Therefore, the abnormal regulation of alternative splicing plays a crucial role in malignant transformation, development, and progression, a fact supported by the distinct splicing profiles identified in both healthy and tumor cells.

Screening for Helicobacter pylori infection and Clarithromycin resistance using Real-Time Polymerase Chain Reaction.

Objective: Helicobacter pylori (H. pylori) infection is spread worldwide and affects at least half of the world's population. Infected people are at increased risk of several diseases' development, including gastric adenocarcinoma.

Serum Levels of Fibroblast Growth Factor 19 Correlate with the Severity of Diarrhea and Independently from Intestinal Inflammation in Patients with Inflammatory Bowel Disease or Microscopic Colitis.

Background: In chronic diarrhea patients, massive over-reporting symptom-based criteria for functional bowel disorders are pitfalls. There is currently no objective biomarker that may provide a correct correlation with the severity of chronic diarrhea. To clarify the role of fibroblast growth factor-19 (FGF-19) as a biomarker of objective measurements of the severity of diarrhea in comparison with a patientreported outcome, based on the Bristol Stool Form (BSF) Scale.

Common variable immune deficiency, central diabetes insipidus, and anemia.

Common variable immune deficiency (CVID) accounts for approximately 20% of all cases of primary immune deficiencies, and is characterized by low serum levels of IgG, IgA, and/or IgM. The diagnosis is usually made between 20 and 40 years of age, sometimes earlier. CVID patients are divided into two major groups based on complications observed: 1 group consists of patients with predominant infections, and 2 group includes patients with inflammatory and/or hematological complications, such as lymphadenopathy, splenomegaly, autoimmune cytopenia, enteropathy, and/or granulomatous conditions.

Macroscopic and microscopic fluorescence spectroscopy of colorectal benign and malignant lesions - diagnostically important features.

Fluorescence spectroscopy is a sensitive, fast and non-invasive tool for a diagnostics of cancerous gastrointestinal lesions. It could be applied for detection of tumours during primary endoscopic observations or as add-on measurement modality during microscopic observations of tissue histology slides for their initial or retrospective diagnosis. Therefore, we are looking for diagnostically important features of normal and cancerous tissue areas in a broad spectral range for gastrointestinal tissues ex vivo using two steady-state macroscopic fluorescent spectroscopic modalities and by confocal fluorescent microscopic detection.
