Real-Time, Intraoperative Doppler/Ultrasound Monitoring of Islet Infusion During Total Pancreatectomy With Islet Autotransplant: A First Report.

Chronic pancreatitis (CP), secondary to a wide variety of etiologies, is a progressive and irreversible disease. Initially, CP is managed with endoscopic interventions, long-term analgesia for its associated chronic abdominal pain syndrome and pancreatic enzyme replacement for exocrine dysfunction. As the disease advances, pancreatic drainage procedures and partial resections are considered, but they leave diseased tissue behind and usually result in short-term relief only.

Kidney After Intestinal Transplantation Using Two Different Living Donors: A First Case Report.

We describe a unique case of a 53-year-old woman who underwent a nonrelated living donor kidney transplant 9 years after a previous small bowel transplant from her sister. The patient had suffered from short bowel syndrome secondary to volvulus after undergoing bariatric surgery for morbid obesity. Her entire small bowel had to be resected emergently, but she also developed acute kidney failure at the time.

Bitter and sweet taste receptors regulate human upper respiratory innate immunity.

Bitter taste receptors (T2Rs) in the human airway detect harmful compounds, including secreted bacterial products. Here, using human primary sinonasal air-liquid interface cultures and tissue explants, we determined that activation of a subset of airway T2Rs expressed in nasal solitary chemosensory cells activates a calcium wave that propagates through gap junctions to the surrounding respiratory epithelial cells. The T2R-dependent calcium wave stimulated robust secretion of antimicrobial peptides into the mucus that was capable of killing a variety of respiratory pathogens.

Surfactants in the management of rhinopathologies.

Background: Surfactants are a class of amphiphilic surface active compounds that show several unique physical properties at liquid-liquid or liquid-solid surface interfaces including the ability to increase the solubility of substances, lower the surface tension of a liquid, and decrease friction between two mediums. Because of these unique physical properties several in vitro, ex vivo, and human trials have examined the role of surfactants as stand-alone or adjunct therapy in recalcitrant chronic rhinosinusitis (CRS).

Methods: A review of the literature was performed.
