BACKGROUND Paragangliomas are rare neoplasms that originate from the neural crest. They are malignant in approximately 10% of cases, with a 50% survival rate at 5 years from diagnosis. In most cases, manifestations of malignancy (such as metastasis) are lacking, and paragangliomas are considered benign lesions. Pancreatic paragangliomas are extremely rare,(More)

BACKGROUND Hemodiafiltration with on-line endogenous reinfusion (HFR) is an extracorporeal dialytic method that combines diffusion, convection and adsorption. HFR-Supra (HFR-S) is a second-generation system with increased convective permeability and adsorption capability. Previous studies suggested that HFR reduces oxidative stress compared to standard(More)
INTRODUCTION Broncho-esophageal fistula is a rare clinical condition which can be manifested with non-specific signs and symptoms. PRESENTATION OF A CASE Here, we report an adult case of a broncho-esophageal fistula in a 43-year-old man referred for chronic cough after fluid food intake and weight loss.
