INTRODUCTION: Complete circular endoscopic (submucosal) resection (CER) performed using the endoscopic submucosal dissection (ESD) technique is burdened with a high incidence of post-operative strictures in the esophagus. The most effective method of preventing them is not known so far; one of the possible methods is to prevent these strictures directly at the site of their formation by covering the defect with a stent. The aim of the study was to find a way to fix a selected biomaterial to a stent, and subsequently, to fix the stent at the CER site to prevent esophageal strictures in an animal model...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) causes irreversible loss of lung function. People with IPF have increased concentrations of autotaxin in lung tissue and lysophosphatidic acid (LPA) in bronchoalveolar lavage fluid and exhaled condensate. GLPG1690 (Galapagos, Mechelen, Belgium) is a novel, potent, selective autotaxin inhibitor with good oral exposure. We explored the effects of GLPG1690 in patients with IPF. METHODS: This was a randomised, double-blind, placebo-controlled phase 2a study done in 17 centres in Italy, Ukraine and the UK...

We report a case of a fetus diagnosed at 28 weeks' gestation with a spontaneous prenatal hemothorax. Fetal intervention consisted of 2 thoracenteses with analysis of the pleural effusion. The pregnancy was further complicated by recurrence of the hemothorax, with subsequent mediastinal shift, hydrops, and nonreassuring antenatal testing requiring delivery at 31 weeks' gestation. Postnatal workup established the diagnoses of cutis marmorata telangiectatica congenita (CMTC) and pulmonary lymphangiectasia. The child is currently 4 years old and without any active medical issues or sequelae from the CMTC, pulmonary lymphangiectasia, or prenatal interventions...

In Argentina there is little information about diseases that affect exotic ungulates and the health risks that they pose to native wildlife, livestock, and humans. The aim of this study was to evaluate the health status of red deer ( Cervus elaphus) in the Nahuel Huapi National Park and surrounding areas in Patagonia, Argentina. During three consecutive hunting seasons, necropsies were performed on 101 red deer, and tissues were examined histologically. The most common lesions were those associated with hepatic and pulmonary parasites...

BACKGROUND: This paper describes our experience with penetrating pharyngo-esophageal injuries (PEI) in the light of a selective conservative approach, and has the objective to define criteria for non-operative management (NOM). METHODS: This retrospective single-center review of patients with penetrating neck injury (PNI) treated for confirmed PEI over a 6-year period aimed to test our proposed hypothesis that NOM is safe for hemodynamically stable patients with PEI, who have no competing indications for exploration, have no established sepsis and who have a water-soluble contrast swallow (WS-swallow) either showing no- or a contained extravasation...

Mediastinal gray zone lymphoma (MGZL) is a provisional entity with intermediate features between classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma. Outcomes for patients with MGZL are reportedly poorer than those for patients with cHL or primary mediastinal large B-cell lymphoma. Additionally, no standard management guidelines for patients with MGZL are available, primarily due to its recent identification, rarity, and challenges in diagnosis. Although recent several studies have suggested dose-adjusted EPOCH-R (etoposide, doxorubicin, vincristine, cyclophosphamide, prednisolone, and rituximab) may improve outcomes in patients with MGZL, numerous patients still suffer from relapsed/refractory MGZL, and the optimal management for such patients remains uncertain...

OBJECTIVE: Introduction: Nowadays operative treatment of corrosive esophageal strictures remains one of the difficult and unsolved problems in surgery. The level of postoperative complications such as anastomotic leak (develops in 7-30% of cases), infections, pneumonia, pleural empyema, mediastinitis, peritonitis, postoperative corrosive strictures is still rather high. The aim of our work was to improve the results of surgical treatment of patients with corrosive esophageal strictures by analyzing and refining on conservative therapy options as well as differentiated approach to each operative treatment method...

REVIEW
Pascal-Alexandre Thomas
Appropriate lymph node (LN) assessment is a hallmark of surgical quality of curative intent operations for non-small cell lung cancer (NSCLC). Even in the era of extensive pre-treatment work-up including routine PET-scanning and brain imaging, and selective invasive LN evaluation, unexpected LN metastases are found at surgery in more than 10% of patients with a cT1aN0 tumor. Systematic lymphadenectomy minimizes the risk of leaving tumor-LN behind and thus the risk of an incomplete resection, and provides the most truthful pTNM, which is decisive in directing adjuvant chemotherapy...

Introduction: Thymic carcinoma is a rare, invasive mediastinal neoplasm with a tendency to metastasize. They constitute a heterogeneous group of tumors that present differently in terms of both behavior and prognosis. Case report: We present a case of thymic carcinoma in a 55-year-old male patient known to suffer from Myasthenia gravis, whose chief complaints were fatigability, ptosis and coughing. All electromyography studies were done along with excision biopsy to reach the definitive diagnosis...

Pneumomediastinum work-up should focus on differentiating mediastinal organ injuries from alveolar rupture since these two causative mechanisms have a different management and prognosis. After an admission at our Emergency Department, we wanted to challenge the current classification into 'spontaneous' or 'secondary' pneumomediastinum, which reflects the clinical rather than the pathophysiological circumstances and is therefore confusing and inappropriate to our view. We propose a new work-up algorithm based on clinical risks factors and chest CT findings...

Myasthenia gravis can develop after resection of thymic tumors. Post-thymectomy myasthenia gravis can be heralded by elevated preoperative anti-acetylcholine-receptor antibodies. Thymic tissue in isolated mediastinal areas can be the culprit lesion and identified by PET SCAN. Re-resection in selected patients can lead to remission of this rare disease.

BACKGROUND: In case of suspicious lymph nodes on computed tomography (CT) or fluorodeoxyglucose positron emission tomography (FDG-PET), advanced tumour size or central tumour location in patients with suspected non-small cell lung cancer (NSCLC), Dutch and European guidelines recommend mediastinal staging by endosonography (endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS)) with sampling of mediastinal lymph nodes. If biopsy results from endosonography turn out negative, additional surgical staging of the mediastinum by mediastinoscopy is advised to prevent unnecessary lung resection due to false negative endosonography findings...
