M M A Abumandour, N E R El-Bakary
The present study represents the first definitive anatomical description of the oropharyngeal cavity of the coot Fulica atra. For this purpose, the organs of six birds were prepared to examine grossly and by SEM and stereomicroscope. The oval lingual apex had multiple overlapping branched acicular processes on its anterior and lateral border. The lingual apex and body had multiple caudally directed filiform-like papillae. By stereomicroscopy, the lingual root had a characteristic appearance and consisted of four parts...

Schistosomes are parasitic helminths that cause schistosomiasis, a disease affecting circa 200 million people, primarily in underprivileged regions of the world. Schistosoma mansoni is the most experimentally tractable schistosome species due to its ease of propagation in the laboratory and the high quality of its genome assembly and annotation. Although there is growing interest in microRNAs (miRNAs) in trematodes, little is known about the role these molecules play in the context of developmental processes...

Xiuzhen Yang, Jingjing Ye, Zhan Gao
In this article, we report a rare case of double aortic arch. The case presented initially with a foreign object in the oesophagus. The patient was a 2-year-old boy, who was referred with primary symptoms of tussis (15 days) and emesis (2 days). He had a history of ingesting a coin. Routine chest X-ray indicated a rounded, metal foreign object in the upper oesophagus. A half-Yuan coin was removed by gastroduodenoscopy. Echocardiographic imaging suggested that the patient had double aortic arch, which was subsequently diagnosed by CT angiography with three-dimensional reconstruction...

In contrast to two-dimensional bioluminescence imaging, three dimensional diffuse light imaging tomography with integrated micro-computed tomography (DLIT-μCT) has the potential to realise spatial variations in infection patterns when imaging experimental animals dosed with derivatives of virulent bacteria carrying bioluminescent reporter genes such as the lux operon from the bacterium Photorhabdus luminescens. The method provides an opportunity to precisely localise the bacterial infection sites within the animal and enables the generation of four-dimensional movies of the infection cycle...

Retropharyngeal abscess is an infection involving the retropharyngeal space which is posterior to the pharynx and oesophagus, and it results as a complication of a primary infection elsewhere in the head and neck including the nasopharynx, paranasal sinuses, or middle ear, which drain lymph to the retropharyngeal lymph nodes. Their lymph nodes are prominent in children and atrophy with age. Therefore, retropharyngeal abscess is most frequently encountered in children, with 75% of cases occurring before the age of 5 years, and often in the first year of life...

BACKGROUND: Remnant dimension is considered one of the crucial elements determining the success of sleeve gastrectomy (SG), and dilation of the gastric fundus is often believed to be the main cause of failure. OBJECTIVES: The main outcome of this study is to find correlations between remnant morphology in the immediate post-operative stage, its dilation in years, and the long-term results. The second purpose aims to correlate preoperative eating disorders, taste alteration, hunger perception, and early satiety with post-SG results...

BACKGROUND: Diagnosis and management of poorly differentiated gastro-entero-pancreatic (GEP) neuroendocrine carcinomas (NECs) remain challenging. Recent studies suggest prognostic heterogeneity. We designed within the French Group of Endocrine Tumours a prospective cohort to gain insight in the prognostic stratification and treatment of GEP-NEC. PATIENTS AND METHODS: All patients with a diagnosis of GEP-NEC between 1st January 2010 and 31st December 2013 could be included in this national cohort...

OBJECTIVE: To report the removal of an ingested clam shell that was firmly impacted in the oesophagus. CLINICAL PRESENTATION AND INTERVENTION: A 77-year-old man presented with acute dysphagia after eating a seafood "risotto" at our hospital. Anurgent dedicated studies (non-contrast helical multislice computed tomography scan of the neck and flexible esophagoscopy) detected a clam shell lodged in the upper esophagus. After several unsuccessful endoscopic attempts, a life-saving cervical esophagotomy was performed and theforeign body was retrieved...

Background. Bezoars are well established entities causing gastrointestinal obstructions. Depending on the prominent constituent of these bezoars, the latter are divided into four subtypes: pharmacobezoars, lactobezoars, trichobezoars, and phytobezoars. Less frequently reported types of bezoars are reported including those formed secondary to nasogastric tube feeding with casein-based formulas. Case Presentation. A 69-year-old male presented following cardiac arrest postmyocardial infarction. Patient sustained anoxic brain injury after resuscitation, rendering him ventilator dependant along with nasogastric tube feeding, initially...

Knowledge about the association between alcohol and Barrett's oesophagus and reflux oesophagitis is conflicting. In this case-control study we evaluated the role of specific alcoholic beverages (red and white wine, beer and liquors) in 339 Barrett's oesophagus and 462 oesophagitis patients compared with 619 endoscopic controls with other disorders, recruited in twelve Italian endoscopic units. Data on alcohol and other individual characteristics were obtained from structured questionnaires. No clear, monotonic significant dose-response relationship was pointed out for red wine...

Secondary graft-oesophageal fistula is a fatal complication of aortic arch replacement. We report a successful two-stage surgical management of a graft-oesophageal fistula seen in a 68-year-old woman 3 years after total aortic arch replacement. She presented with a prolonged intractable fever without haematemesis. The fistula occurred between the distal aortic anastomosis and oesophagus; the entire graft was surrounded by air. In the first-stage operation, we performed re-replacement of the entire infected graft, oesophagectomy with cervical oesophagostomy, omental transfer and cervical routing of the stomach roll, through an extended left thoracotomy incision with sternal transection...

Objectives The purpose of the present study was to describe histologically the gastro-oesophageal junction in the cat and interrelationships of this region. Our hypothesis was that cats are devoid of abdominal oesophagus. Methods Three centimetres of the terminal oesophagus, the phreno-oesophageal membrane with 1-2 cm margins of the diaphragmatic crural muscle and the proximal 3 cm of the gastric cardia were obtained from nine domestic shorthair cats and one domestic longhair cat that were euthanased for reasons other than digestive tract pathology...

The term 'visceral fascia' is a general term used to describe the fascia lying immediately beneath the mesothelium of the serosa, together with that immediately surrounding the viscera, but there are many types of visceral fasciae. The aim of this paper was to identify the features they have in common and their specialisations. The visceral fascia of the abdomen (corresponding to the connective tissue lying immediately beneath the mesothelium of the parietal peritoneum), thorax (corresponding to the connective tissue lying immediately beneath the mesothelium of the parietal pleura), lung (corresponding to the connective tissue under the mesothelium of the visceral pleura), liver (corresponding to the connective tissue under the mesothelium of the visceral peritoneum), kidney (corresponding to the Gerota fascia), the oesophagus (corresponding to its adventitia) and heart (corresponding to the fibrous layer of the pericardial sac) from eight fresh cadavers were sampled and analysed with histological and immunohistochemical stains to evaluate collagen and elastic components and innervation...

The optimal management of resectable oesophageal adenocarcinoma is controversial, with many centres using neoadjuvant chemotherapy following the Medical Research Council (MRC) oesophageal working group (OE02) trial and the MRC Adjuvant Gastric Infusional Chemotherapy (MAGIC) trial. The more intensive MAGIC regimen is used primarily in gastric cancer but some also use it for oesophageal cancer. A database of cancer resections (2001-2013) provided information on survival of patients following either OE02 or MAGIC-type treatment...

Malignancies of the nasal cavity and paranasal sinuses are well known, but have uncommon presentations. Late diagnosis and local extension are significant prognostic factors associated with a poorer treatment outcome. Thus, refinements of the diagnostic procedures to enhance the sensitivity of the clinical evaluation are desirable. We here describe a case of endonasal lymphoma, in which the lesion was hardly visible and initially ignored at ordinary white light (WLI) nasoendoscopy, but easily recognisable, clearly pathogenic and well demarcated when illuminated with narrow band imaging (NBI) at a later session...

Oesophageal fistulae after thoracic endovascular aneurysm repair (TEVAR) for thoracic aortic aneurysm (TAA) have been reported, although the causes are unknown. One hypothesis is that the structural configuration of the aortic aneurysm, as it protrudes towards the oesophagus, may affect oesophageal fistula formation. The pathological findings of an oesophageal fistula following TEVAR are reviewed here. This report presents the case of a 68-year-old man with a stent graft-related oesophageal fistula after TEVAR for TAA...

Foreign body ingestion and foreign body aspiration commonly affect young children between 6 months and 6 years. A large number of these events remain unwitnessed and asymptomatic while the swallowed foreign body traverses the gastrointestinal tract and is passed in the stool. Recent literature has shown an increase in morbidity associated with button battery and (neomydium) magnet ingestions in children, particularly over the last decade. Early identification and management in a time critical manner is required in cases where button batteries get lodged in the oesophagus or multiple magnets are swallowed...

Oesophageal sarcomas are very rare while various histological types have occasionally been reported. Malignant Peripheral Nerve Sheath Tumour (MPNST) of the oesophagus is an exceedingly rare type of oesophageal sarcoma with only thirteen cases previously reported in the world literature. However, it should be included in the differential diagnosis of oesophageal neoplasias. Due to the small number of reported cases, the information about the biological behaviour of this entity is still insufficient. While MPNST is generally considered an aggressive type of tumour with high recurrence rates after surgical treatment and poor prognosis, previous reports of cases with oesophageal localization have recorded satisfactory outcomes overall even with less aggressive therapeutic approaches, although a long-term follow-up is lacking...

OBJECTIVE: In previous studies using oesophageal squamous cells from patients with Barrett's oesophagus (normal oesophageal squamous (NES)-B cells) and from patients without Barrett's oesophagus (NES-G cells), we showed that acid and bile salts induced caudal-related homeobox transcription factor 2 (CDX2) expression only in NES-B cells. CDX2, a transcription factor required to form intestinal epithelium, is a target of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signalling, which can be inhibited by aspirin...
