BACKGROUND Injection for interdigital neuroma (IDN) may not selectively target the common digital nerve. We investigated the anatomical localization and extent of extravasation with injection for IDN. METHODS Two fellowship-trained foot and ankle surgeons injected radiopaque contrast into the third webspace of 49 cadaveric specimens (29 with 2 mL and 20 with 1 mL). Computed tomography scan of...

Advanced glycation end products (AGEs) are nonenzymatic glycosylated adducts of proteins that accumulate in vascular tissue during diabetes and aging. The aim of this work was to study the role of AGEs and of the oxidative mechanisms in diabetes-induced changes in vascular permeability. Intravital videomicroscopy was used to study albumin microvascular leakage in cremaster muscle. The extravasa...

Immediate allergic reactions are initiated by allergen-induced, specific IgE-mediated mast cell degranulation and involve leukocyte recruitment into the inflamed site. We compared conjunctival signs, symptoms, and in vivo leukocyte rolling and extravasation into sites of inflammation in five patients allergic to birch pollen and in 10 nonallergic controls who received a challenge to birch aller...

The efficacy of novel cancer therapeutics can be hampered by inefficient delivery of agents to the tumor at effective concentrations. Liposomes have been used as a method to overcome some delivery issues and, in combination with hyperthermia, have been shown to increase drug delivery to tumors. This study investigates the effects of a range of temperatures (34–42°C) and hyperthermia treatment s...

The efficacy of novel cancer therapeutics has been hampered by the ability to deliver these agents to the tumor at effective concentrations. Liposomes have been used as a method to overcome some delivery issues and, in combination with hyperthermia, have been shown to increase drug delivery to tumors. Particle size has been shown to affect the delivery of liposomes, but it is not known how hype...

Capsaicin increases the permeability of blood vessels in the rat tracheal mucosa through a mechanism involving the release of tachykinins from sensory nerves. This capsaicin-induced increase in vascular permeability is potentiated by viral infections of the respiratory tract. The present study was done to determine whether this "neurogenic plasma extravasation" can be inhibited by glucocorticoi...
