Two-Year Experience of 14 French Pigtail Catheters Placed by Procedure-Focused Hospitalists.

Background: Recent studies show small-bore chest tubes, commonly 14 French pigtail catheters (PCs), are noninferior to large-bore chest tubes for treating various conditions, and they are associated with better patient comfort. The Medical College of Wisconsin implemented a bedside procedure service (BPS) that has been trained in the placement of PCs as an adjunct to its interventional radiology department.

Methods: The data regarding consults for PC placement was collected by the BPS over a 2-year period.

The dual pathway inhibitor rigosertib is effective in direct patient tumor xenografts of head and neck squamous cell carcinomas.

The dual pathway inhibitor rigosertib inhibits phosphoinositide 3-kinase (PI3K) pathway activation as well as polo-like kinase 1 (PLK1) activity across a broad spectrum of cancer cell lines. The importance of PIK3CA alterations in squamous cell carcinoma of the head and neck (HNSCC) has raised interest in exploring agents targeting PI3K, the product of PIK3CA. The genetic and molecular basis of rigosertib treatment response was investigated in a panel of 16 HNSCC cell lines, and direct patient tumor xenografts from eight patients with HNSCC [four HPV-serotype16 (HPV16)-positive].

A patient tumor transplant model of squamous cell cancer identifies PI3K inhibitors as candidate therapeutics in defined molecular bins.

Targeted therapy development in head and neck squamous cell carcinoma (HNSCC) is challenging given the rarity of activating mutations. Additionally, HNSCC incidence is increasing related to human papillomavirus (HPV). We sought to develop an in vivo model derived from patients reflecting the evolving HNSCC epidemiologic landscape, and use it to identify new therapies.
