BACKGROUND: Endoscopic resection (ER) with or without ablation is the first choice treatment for early Barrett's neoplasia. Adequate staging is important to assure a good oncological outcome. OBJECTIVE: The purpose of this study was to investigate the diagnostic accuracy of pre-operative biopsies in patients who undergo ER for high-grade dysplasia (HGD) or early adenocarcinoma (EAC) in Barrett's oesophagus (BE) and the cardia. METHODS: Between November 2005-May 2012, 142 ERs performed in 137 patients were obtained...

It is important to understand sex and gender-related differences in gastroesophageal reflux disease (GERD) because gender-related biologic factors might lead to better prevention and therapy. Non-erosive reflux disease (NERD) affects more women than men. GERD symptoms are more frequent in patients with NERD than in those with reflux esophagitis. However, men suffer pathologic diseases such as reflux esophagitis, Barrett's esophagus (BE), and esophageal adenocarcinoma (EAC) more frequently than women. The prevalence of reflux esophagitis is significantly increased with age in women, especially after their 50s...

Nurses manage patients with common infectious diseases by following institutional guidelines based on expert advice, evidence in the literature, and a wealth of experience. Today nurses are challenged to provide care to patients with multidrug-resistant organisms and virulent infectious diseases such as Ebola virus disease. Management of some patients with virulent infectious diseases occurs in the context of minimal experience with the pathogen, course of infection, diagnostics, nursing care, and treatment...

Magnetic microbeads exhibit rapid separation characteristics and are widely employed for biomolecule and cell isolations in research laboratories, clinical diagnostics assays, and cell therapy manufacturing. However, micrometer particle diameters compromise biomarker recognition, which leads to long incubation times and significant reagent demands. Here, a stimuli-responsive binary reagent system is presented that combines the nanoscale benefits of efficient biomarker recognition and the microscale benefits of rapid magnetic separation...

A 9 yr old rat terrier presented with corneal ulceration and conjunctivitis that developed acutely after digging among dry leaves in wooded northern Arizona. Ophthalmic examination revealed multiple linear foreign bodies throughout the adnexal tissue and cornea of the left eye. Manual removal of material was unsuccessful. The palpebral conjunctiva required excision with tenotomy scissors to remove structures and allow corneal healing. Microscopic examination revealed structures believed to be setae from a Theraphosidae tarantula...

The pathogenesis of precursor lesions of gastrointestinal tumors is manifested in many ways. In the esophagus an aberrant genetic expression of intestinal transcription factors, such as CDX2 is initiated by local environment factors. During the subsequent dysplasia to carcinoma sequence, chromosomal gain and loss of genes occurs. A 4-color fluorescence in situ hybridization (FISH) assay can be applied in dysplasia as well as in Barrett's adenocarcinoma to define prognostic marker combinations. In the gastric carcinogenesis sequence the gene expression of CDX1 is regulatively dependent on an interplay between inflammation and promotor methylation...

Aim To determine how many ameloblastomas were misdiagnosed as dentigerous cysts (DCs) by correlating the radiological and histopathological features of a series of both entities. Methods and results Histopathology reports and radiological imaging of 135 DCs and 43 ameloblastomas were reviewed. Any clinical or radiological feature that suggested that the diagnosis of DC was wrong-for example, absence of an unerupted tooth-prompted review of the original histology. A total of 34 cases coded as DC at diagnosis were excluded; in the remaining 101 patients, the clinicoradiological and histopathological features were consistent with DC in 96 (95...

BACKGROUND: Intellectual disability (ID) is often accompanied by delays in emotional development (ED) that may result in challenging behavior. Insight into emotional functioning is crucial for appropriate diagnostic assessment in adults with ID. However, few standardized assessment instruments are available. AIMS: The aim of this study was to develop a short, psychometrically sound instrument for assessing levels of ED in individuals with ID: The Scale of Emotional Development - Short (SED-S), which can be applied to adults...

Barrett's esophagus (BE) is defined as the extension of salmon-colored mucosa into the tubular esophagus ≥ 1 cm proximal to the gastroesophageal junction with biopsy confirmation of intestinal metaplasia. Patients with BE are at increased risk of esophageal adenocarcinoma (EAC), and undergo endoscopic surveillance biopsies to detect dysplasia or early EAC. Dysplasia in BE is classified as no dysplasia, indefinite for dysplasia (IND), low grade dysplasia (LGD) or high grade dysplasia (HGD). Biopsies are diagnosed as IND when the epithelial abnormalities are not sufficient to diagnose dysplasia or the nature of the epithelial abnormalities is uncertain due to inflammation or technical issues...

The tumor suppressor phosphatase and tensin homolog (PTEN) negatively regulates phosphatidylinositol 3-kinase (PI3K)-AKT signaling and is often inactivated by mutations (including deletions) in a variety of cancer types, including T-cell acute lymphoblastic leukemia. Here we review mutation-associated mechanisms that inactivate PTEN together with other molecular mechanisms that activate AKT and contribute to T-cell leukemogenesis. In addition, we discuss how Pten mutations in mouse models affect the efficacy of gamma-secretase inhibitors to block NOTCH1 signaling through activation of AKT...

Clonal evolution to esophageal adenocarcinoma in Barrett's esophagus (BO) is characterized by relentless clonal competition. Developing markers that capture the dynamics of clonal competition in BO patients for risk stratification purposes is a key goal of translational research. Dysplastic epithelial changes in patients who progress to neoplasia can be viewed as a proxy marker of the clonal dynamics in BO progression. However, this marker is relatively insensitive because it does not pick up on clonal expansions that are not accompanied by morphologic changes...

Little is known about ageing with autism spectrum disorder (ASD). We examined the characteristics of adults referred to a specialist diagnostic centre for assessment of possible ASD, 100 of whom received an ASD diagnosis and 46 did not. Few demographic differences were noted between the groups. Comorbid psychiatric disorders were high in individuals with ASD (58 %) and non-ASD (59 %). Individuals who received an ASD diagnosis had higher self-rated severity of ASD traits than non-ASD individuals. Within the ASD group, older age was associated with higher ratings of ASD traits and better cognitive performance...

BACKGROUND: Infection with Helicobacter pylori is associated with severe digestive diseases including chronic gastritis, peptic ulcer disease, and gastric cancer. Successful eradication of this common gastric pathogen in individual patients is known to prevent the occurrence of peptic ulcer disease and gastric cancer. DISCUSSION: With half of the world's population being infected with H, pylori and only few antibiotics result in an effective eradication, a successful antibiotic driven worldwide eradication program seems unlikely...

BACKGROUND: Depression is a common, debilitating, and costly disorder. Many patients request psychological therapy, but the best-evidenced therapy-cognitive behavioural therapy (CBT)-is complex and costly. A simpler therapy-behavioural activation (BA)-might be as effective and cheaper than is CBT. We aimed to establish the clinical efficacy and cost-effectiveness of BA compared with CBT for adults with depression. METHODS: In this randomised, controlled, non-inferiority trial, we recruited adults aged 18 years or older meeting Diagnostic and Statistical Manual of Mental Disorders IV criteria for major depressive disorder from primary care and psychological therapy services in Devon, Durham, and Leeds (UK)...
