Lymphangioleiomyomatosis manifesting as refractory chylothorax and chyloperitoneum.

This is a rare case of sporadic lymphangioleiomyomatosis (S-LAM) manifesting as refractory chylothorax and chyloperitoneum. A middle-aged woman with unremarkable medical history presented with respiratory failure, abdominal distension and anasarca. She was found to have high-output chylous effusion that required chest tube drainage, as well as chylous ascites.

Microbial Keratitis at an Urban Public Hospital: A 10-Year Update.

Purpose: To review the epidemiology, risk factors, microbiologic spectrum, and treatment of microbial keratitis during a five-year period at an urban public hospital with comparison to similar findings a decade earlier at the same hospital.

Methods: Retrospective chart review in the 5-year interval 2009 through 2014 compared to previously reported cases 2000 through 2004 [Eye & Contact Lens 33(1): 45-49, 2007]. Comparative primary outcome measures included best-corrected visual acuity (BCVA), risk factors, culture and sensitivities, treatment, and complication rates.

A carbon nanotube-based Raman-imaging immunoassay for evaluating tumor targeting ligands.

Herein, we describe a versatile immunoassay that uses biotinylated single-walled carbon nanotubes (SWNTs) as a Raman label, avidin-biotin chemistry to link targeting ligands to the label, and confocal Raman microscopy to image whole cells. Using a breast tumor cell model, we demonstrate the usefulness of the method to assess membrane receptor/ligand systems by evaluating a monoclonal antibody, Her-66, known to target the Her2 receptors that are overexpressed on these cells. We present two-dimensional Raman images of the cellular distribution of the SWNT labels corresponding to the distribution of the Her2 receptors in different focal planes through the cell with validation of the method using immunofluorescence microscopy, demonstrating that the Her-66-SWNT complexes were targeted to Her2 cell receptors.
