Fluorescence-mediated Tomography for the Detection and Quantification of Macrophage-related Murine Intestinal Inflammation

Murine models of disease are indispensable to scientific research. However, many diagnostic tools such as endoscopy or tomographic imaging are not ...

Undifferentiated embryonal sarcoma of the liver (UESL), a rare tumor that predominantly affects children, generally has been considered an aggressive neoplasm with an unfavorable prognosis. More recent reports have indicated that modern multimodal treatment and supportive care improve the survival of children with UESL. Data regarding the treatment and survival of adults have not been reviewed comprehensively, and only a few adult patients with UESL have been reported in the literature.

Fatal course of esophageal stenting of an atrioesophageal fistula after atrial fibrillation ablation.

Differentiation between inflammatory and fibromatous strictures in Crohn's disease (CD) is difficult but crucial for therapeutic decisions. The aim of this study was to assess the best noninvasive imaging method for the detection and differentiation of inflammatory and fibromatous stenoses in CD in comparison to endoscopic and histologic evaluation.

Detection and differentiation of inflammatory versus fibromatous Crohn's disease strictures: prospective comparison of 18F-FDG-PET/CT, MR-enteroclysis, and transabdominal ultrasound versus endoscopic/histologic evaluation.

Diff&eacute;renciation entre les st&eacute;noses inflammatoires et fibromateux dans la maladie de Crohn (MC) est difficile mais crucial pour les d&eacute;cisions th&eacute;rapeutiques. Le but de cette &eacute;tude &eacute;tait d&#39;&eacute;valuer la meilleure m&eacute;thode d&#39;imagerie non invasive pour la d&eacute;tection et la diff&eacute;renciation des st&eacute;noses inflammatoires et fibromateux en CD en comparaison de l&#39;&eacute;valuation endoscopique et histologique.

Differenziazione tra stenosi infiammatorie e fibromatous nella malattia di Crohn (CD) &egrave; difficile ma fondamentale per le decisioni terapeutiche. Lo scopo di questo studio era di valutare il miglior metodo di imaging non invasivo per l&#39;individuazione e la differenziazione delle stenosi infiammatorie e fibromatous nel CD rispetto alla valutazione endoscopica e istologica.

Rilevamento e differenziazione di infiammatoria contro stenosi di malattia di Crohn fibromatous: confronto prospettico dell&#39;ecografia transaddominale 18F-FDG-PET/CT e MR-enteroclysis versus endoscopica ed istologica.

Bile duct stones that cannot be removed endoscopically are still a challenge in interventional gastroenterology. Extracorporeal shockwave lithotripsy (ESWL) with subsequent endoscopic extraction of residual fragments is an established treatment option if other endoscopic means are not successful. Our study aimed to investigate the efficacy and safety of ESWL for clearance of refractory bile duct stones.

Clearance of refractory bile duct stones with Extracorporeal Shockwave Lithotripsy: higher failure rate in obese patients.

Idiopathic achalasia is a severe motility disorder of the esophagus and is characterized by a failure of the lower esophageal sphincter to relax due to a loss of neurons in the myenteric plexus. Most recently, we identified an eight-amino-acid insertion in the cytoplasmic tail of HLA-DQβ1 as strong achalasia risk factor in a sample set from Central Europe, Italy and Spain. Here, we tested whether the HLA-DQβ1 insertion also confers achalasia risk in the Polish and Swedish population. We could replicate the initial findings and the insertion shows strong achalasia association in both samples (Poland P=1.84 × 10(-04), Sweden P=7.44 × 10(-05)). Combining all five European data sets - Central Europe, Italy, Spain, Poland and Sweden - the insertion is achalasia associated with Pcombined=1.67 × 10(-35). In addition, we observe that the frequency of the insertion shows a geospatial north-south gradient. The insertion is less common in northern (around 6-7% in patients and 2% in controls from Sweden and Poland) compared with southern Europeans (~16% in patients and 8% in controls from Italy) and shows a stronger attributable risk in the southern European population. Our study provides evidence that the prevalence of achalasia may differ between populations.

The HLA-DQβ1 insertion is a strong achalasia risk factor and displays a geospatial north-south gradient among Europeans.

Although an eight-residue insertion in HLA-DQβ1 has been recently identified as a genetic risk factor for idiopathic achalasia, other risk factors are still unknown. In the present study, we carried out an epidemiological survey and a genotype-phenotype (G×P) analysis to gain further insights into the etiology of achalasia.
