Large Nasopharyngeal Hairy Polyp Causing Immediate Respiratory Distress at Birth.

This article presents a rare case of a large hairy polyp, a developmental malformation causing a benign tumor, within the nasopharynx. The patient, born with the polyp obstructing the airway, required immediate intubation and a combined transnasal-transoral surgical approach for excision. The case underscores the challenges in diagnosing and managing such polyps, emphasizing the importance of imaging for surgical planning, and the consideration of multiple approaches to ensure complete resection and prevent recurrence.

Endoscopic trans-pterygoid resection of a low-grade cribriform cystadenocarcinoma of the infratemporal fossa.

This article presents a case of low-grade cribriform cystadenocarcinomas (LGCCC), a rare salivary gland tumor manifesting in the infratemporal fossa (ITF). The lesion in this case is unique in its location, histopathology, and management in that the tumor resection was performed using an exclusively endoscopic, endonasal approach. This case highlights the expanding application of endoscopic skull base techniques to address an indolent, slow-growing malignancy of the ITF.

Large-bowel disease presenting as small-bowel obstruction is associated with a poor prognosis.

Introduction: Small-bowel obstruction (SBO) is a common cause of admission to the surgical service. On rare occasions, a diagnosed SBO is actually due to large-bowel pathology combined with an incompetent ileocecal valve. The purpose of this study was to investigate this phenomenon.

Anti-inflammatory effects of miR-21 in the macrophage response to peritonitis.

We investigated the role of microRNA-21 in the macrophage response to peritonitis; microRNA-21 expression increases in peritoneal macrophages after lipopolysaccharide stimulation but is delayed until 48 hours after cecal ligation and puncture. MicroRNA-21-null mice and bone marrow-derived cell lines were exposed to cecal ligation and puncture or lipopolysaccharide, and survival, microRNA-21 levels, target messenger RNAs and proteins, and cytokines were assayed. Macrophages were also transfected with microRNA-21 mimics and antagomirs, and similar endpoints were measured.
