Mycoplasma gallisepticum (MG) is a bacterial pathogen that causes production losses in layer chickens. To combat MG, multiage layer facilities vaccinate pullets by either spray or eye-drop vaccination. The objective in this study was to evaluate the use of in ovo vaccination as a potential alternative for MG vaccination. Layer embryos at 18 d of incubation were either not-injected (control), or were hand-injected with either commercial Marek's disease vaccine diluent alone or with a high, medium, low, or very low dosage of a live attenuated strain F (FMG) vaccine suspended in the commercial diluent...

Mixed adenoneuroendocrine carcinoma (MANEC) in the esophagus is an infrequent but highly malignant cancer with few known genomic alterations. We conducted whole-exome sequencing and whole-genome SNP genotyping for 4-6 tumor subregions and 5-6 adjacent normal tissue sites and 1-3 lymph node metastases in two esophageal MANECs to detect somatic mutations and copy number alterations, and to explore their spatial heterogeneity and underlying clonal structure. TP53 mutation, RB1 deletion or LOH, and PIK3CA, PTEN, KRAS, SOX2, DVL3, TP63 amplification appeared in all regions in both tumors...

In radiation treatment planning, the esophagus is an important organ-at-risk that should be spared in patients with head and neck cancer or thoracic cancer who undergo intensity-modulated radiation therapy. However, automatic segmentation of the esophagus from CT scans is extremely challenging because of the structure's inconsistent intensity, low contrast against the surrounding tissues, complex and variable shape and location, and random air bubbles. The goal of this study is to develop an online atlas selection approach to choose a subset of optimal atlases for multi-atlas segmentation to delineate esophagus automatically...

Pneumatosis intestinalis is a radiographic finding that represents a spectrum of conditions ranging from benign disease to abdominal sepsis and death. Along with portal venous gas, it is generally considered an ominous sign prompting emergency operative intervention. We report a rare case showing that nonoperative therapy can be considered in a seriously ill patient with esophageal, gastric and portal venous air.

BACKGROUND: Recent studies have identified age-related changes in DNA methylation patterns in normal and cancer tissues in a process that is called epigenetic drift. However, the evolving patterns, functional consequences, and dynamics of epigenetic drift during carcinogenesis remain largely unexplored. Here we analyze the evolution of epigenetic drift patterns during progression from normal squamous esophagus tissue to Barrett's esophagus (BE) to esophageal adenocarcinoma (EAC) using 173 tissue samples from 100 (nonfamilial) BE patients, along with publically available datasets including The Cancer Genome Atlas (TCGA)...

Eosinophilic esophagitis (EoE) is an allergic inflammatory disease of the esophagus mediated by an IL-13-driven epithelial cell transcriptional program. Herein, we show that the cytoskeletal protein synaptopodin (SYNPO), previously associated with podocytes, is constitutively expressed in esophageal epithelium and induced during allergic inflammation. In addition, we show that the SYNPO gene is transcriptionally and epigenetically regulated by IL-13 in esophageal epithelial cells. SYNPO was expressed in the basal layer of homeostatic esophageal epithelium, colocalized with actin filaments, and expanded into the suprabasal epithelium in EoE patients, where expression was elevated 25-fold compared with control individuals...

Sandy Durrani, Marc Rothenberg
Eosinophilic esophagitis is a chronic, antigen-driven, eosinophil-predominant inflammatory disease of the esophagus and affects both children and adults. Cutting-edge technologies, such as genome-wide association studies, have advanced our understanding of the disease pathogenesis at a remarkable rate. Recent insights from genetic and mechanistic studies have concluded that a complex interplay between genetic and environmental risk factors, allergic sensitization, and esophageal-specific pathways leads to disease pathogenesis...

Results: Compared with the control group, the impacted subjects presented marked reduction in amplitude and duration of esophageal contraction in the proximal esophagus. Conclusions: These motor disorders could be responsible for the foreign body impaction in the esophagus. However, we believe this patient group should be further studied by 24-hour esophageal manometry to reach a more accurate diagnosis by studying each patient's entire circadian cycle.

The increasing incidence of adenocarcinoma of the lower esophagus and cardia arising in Barrett's metaplastic epithelium continues to be of great concern because medical and surgical efforts to reverse the process have been disappointing. A potential answer to the problem is removal of the metaplastic epithelium. Modern technology has introduced physical and chemical modalities which facilitate ablation of the neo-epithelium endoscopically. These techniques have been used in several centers, and preliminary results are encouraging...

We report a case of a patient with esophageal tuberculosis, a very uncommon form of extrapulrhonar tuberculosis. Initially, because of constitutional symptomatology and radiological findings of mediastinal lymph node enlargement, lymphoma was considered. However, the endoscopic findings of ulcerative masses and a sinus tract revealed by esophagram were suspicious of tuberculous origin. Diagnosis was achieved after bacterial examination of smear samples from esophageal ulcers that revealed bacillus tuberculous and histological demonstration of caseating granulomas in cervical lymph nodes...

Polypoid tumours of the esophagus present diagnostic and therapeutic problems. Liposarcomas are infrequent among them. We report a recent case. A 73-year-old male patient was seen in May 1995 in the Ear, Nose and Throat (ENT) Department, Clinica Modelo de Morón, with intermittent dysphagia and dyspnoea due to recurrent vomiting. A laryngeal lineal tomography showed a subglottic obstruction due to extrinsic compression. The patient was referred to the Gastroenterology Department, where an upper gastrointestinal (upper GI) series demonstrated mega-esophagus with abundant retained food...

A case of delayed rupture of the thoracic aorta into the esophagus after blunt thoracic injury is reported. It involved a hemodynamically stable 18-year-old male patient without any clinical or radiological signs to indicate aortic injury. Aortoesophageal fistula presented in the fifth post traumatic day, with a sudden dyspnea episode, intraperitoneal hemorrhage and lower gastrointestinal bleeding, due to intraperitoneal and intragastric rupture of intramural esophageal hematoma.

This study assessed the clinical value of CYFRA 21-1 in comparison with squamous cell carcinoma antigen (SCC-Ag), carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA19-9) in patients with esophageal squamous cell carcinoma. In 112 primary cancer patients, the diagnostic sensitivity of CYFRA 21-1 (33.9%) was superior to SCC-Ag (28.6%), CEA (12.5%), and CA19-9 (6.3%). Levels of CYFRA 21-1 were closely correlated with TNM stage and were below the cutoff value in all 21 patients with stage I disease...

Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus diagnosed by the presence of esophageal symptoms accompanied by an esophageal eosinophilic infiltrate. EoE has an increasing worldwide prevalence and can be a cause of dysphagia and food impactions. There is an important role for the use of proton pump inhibitors in the diagnostic pathway of EoE. Treatment paradigms for EoE aim to minimize esophageal inflammation and improve symptom control. Dietary therapy targets dietary allergens and encompasses the elemental diet, the allergy testing-directed elimination diet, and the empiric elimination diet...

Surgery still remains the main stream in the multimodality treatment for locally advanced lung cancer. On the other hand, more than 50% of non-small cell lung cancer are excluded for surgical indications, especially T4 category of lung cancer. In this study, we showed 5 year overall survival rate of both 50 clinical T4 cases and 30 pathological T4 cases are 35.6% and 41.9% respectively. Those could be compared with the non-surgical treatment results in the literature. Through this study and analysis of other reports, we might consider surgical indications for T4 category lung cancer are as follows;invasion to mediastinum, spine, trachea, carina and additional nodules in ipsilateral different lobes with N0-1 status(esophagus is not included in this study)...

Here, we present a case of a 50-year-old male with a history of a Guillain-Barré-syndrome, who was referred to our clinic with recurrent esophageal candidiasis and long-standing intermittent retrosternal cramps for further evaluation. Other symptoms such as dysphagia, regurgitations and weight loss were denied, and prior repeated endoscopy was otherwise unremarkable. Using high resolution impedance manometry, we could demonstrate a panesophageal pressure increase on water swallows and complete aperistalsis of the tubular esophagus, indicating achalasia type II...

Poorly-differentiated neuroendocrine carcinoma of the digestive system has a dismal prognosis with limited treatment options. This study aimed to investigate expression of the PD-1/PD-L1 pathway in these tumors. Thirty-seven patients with a poorly-differentiated neuroendocrine carcinoma of the digestive system were identified. Their electronic medical records, pathology reports and pathology slides were reviewed for demographics, clinical history and pathologic features. Tumor sections were immunohistochemically labeled for PD-1 and PD-L1 and expression of PD-1 and PD-L1 on tumor and tumor-associated immune cells was analyzed and compared between small cell and large cell neuroendocrine carcinomas...
