Spiral enteroscopy is a new technique for endoscopic evaluation of the small bowel. Currently, more than 3000 cases have been performed worldwide. The Discovery SB device has been approved by the Food and Drug Administration and has been granted a CE mark. The technique is safe and effective for management and detection of small bowel pathology. Recent(More)
BACKGROUND Pathologic diagnosis and therapeutic interventions on the small bowel have been difficult and challenging for gastroenterologists. In the last few years, significant advances have been made in this direction. New diagnostic and therapeutic modalities for visualizing the small bowel have been introduced. Furthermore, increased indications for(More)
BACKGROUND Staphylococcus aureus is one of the most common bacteria associated with chronic rhinosinusitis (CRS). Although S. aureus biofilms have been correlated with disease severity in CRS, little is known about the initial immune response that biofilms induce in the sinonasal mucosa. OBJECTIVE The aim of this study was to evaluate the innate immune(More)
BACKGROUND The presence of Staphylococcus aureus biofilms on sinonasal mucosal surfaces is associated with recalcitrant chronic rhinosinusitis (CRS), but little is known about the innate immune response they trigger. We aimed to study the human pattern recognition receptor (PRR) nucleotide-binding oligomerization domain containing 2 (Nod2) receptor and(More)
BACKGROUND Staphylococcus aureus (S. aureus) biofilm has been associated with severe and recalcitrant cases of chronic rhinosinusitis (CRS). However, its role in the pathophysiology of this condition is not completely understood. This study aims to develop a sinonasal tissue explant model to analyze the interaction of S. aureus biofilm with the mucosa in(More)
BACKGROUND & AIMS Urokinase plasminogen activator (uPA) regulates plasmin generation from plasminogen. The aim of this study was to analyze the role of the plasminogen activator/plasmin system in chronic pancreatitis (CP). METHODS Using Northern blot analysis, in situ hybridization, and immunohistochemistry, the expression of uPA, its receptor (uPAR),(More)
BACKGROUND A subgroup of chronic rhinosinusitis with nasal polyps (CRSwNP) patients is refractory to optimal surgical therapy and requires multiple revision sinus operations. Studies have shown that mucosal eosinophilia correlates with disease severity. We hypothesized that a high-grade tissue inflammatory load is associated with these refractory patients.(More)
We report a 37 years old male, coming from Paraguay, who consulted for tinnitus, hearing loss, foreign body sensation and pain in the left ear. He informed that a fly entered into his external auditive channel, five days before consulting. We observed the destruction of the tympanic membrane and 22 live larvae were extracted. Following the larval(More)
Pleomorphic adenoma is the most frequent major salivary glands neoplasm but it is rare in the nasal cavity. We report a case of a 41 years old woman who complains of a left septal mass and unilateral nasal obstruction. Her clinical and CT-scan aspects suggest a benign lesion. The lesion is removed by direct transnasal approach. The histopathological(More)
