The veterinary technician's role in laser surgery.

The use of surgical lasers in veterinary practice has grown significantly since 1996. Many veterinarians have studied and implemented the basic physics and tissue didactics required to successfully incorporate a surgical laser program into their practice. The support role of the veterinary technician is crucial to ensuring an efficient, safe, and successful outcome of any surgical laser procedure. The technician's role may include practice management duties, client communication, and laser safety officer duties. Although there are a variety of lasers, the most common types used in veterinary practice are carbon dioxide (CO2) and diode. This article presents an overview of the veterinary technician's role as a key support person in ensuring a safe and positive outcome in the implementation of CO2 and diode lasers in a veterinary practice.     

Comment on "Intensifying weathering and land use in Iron Age Central Africa"

Bayon et al. (Reports, 9 March 2012, p. 1219) interpreted unusually high aluminum-potassium ratio values in an Atlantic sediment core as indicating anthropogenic deforestation around 2500 years before the present (B.P.). We argue that there is no terrestrial evidence for forest destruction by humans and that the third millennium B.P. rainforest crisis can be clearly attributed mostly to climatic change.     

Gastrointestinal Disease in Exotic Small Mammals

Exotic small mammal medicine is a relatively new specialty area within veterinary medicine. Ferrets, rabbits, and rodents have long been used as animal models in human medical research investigations, resulting in a body of basic anatomic and physiologic information that can be used by veterinarians treating these species. Unfortunately, there is a paucity of veterinary articles that describe clinical presentation, diagnosis, and treatment options of gastrointestinal (GI) disease as it affects exotic small mammals. Although there is little reference material relating to exotic small mammal GI disease, patients are commonly presented to veterinary hospitals with digestive tract disorders. This article provides the latest information available for GI disease in ferrets (Helicobacter mustelae gastritis, inflammatory bowel disease [IBD], GI lymphoma, systemic coronavirus, coccidiosis, and liver disease), rabbits (GI motility disorders, liver lobe torsion, astrovirus, and coccidiosis), guinea pigs (gastric dilatation volvulus [GDV]), rats (Taenia taeniaeformis), and hamsters (Clostridium difficile). Both noninfectious diseases and emerging infectious diseases are reviewed as well as the most up-to-date diagnostics and treatment options.
