Studies were undertaken by the Departments of Otolaryngology-Head and Neck Surgery and Anesthesiology at Northwestern University Medical School and the Medical College of Wisconsin (Milwaukee) to compare the potential for tissue injury to the trachea and lungs of canines. Polyvinylchloride (PVC), Rusch red rubber, and silicone tubes were tested. The effects of an intraluminal tube fire on the larynx and trachea were documented with laryngeal and bronchoscopic photographs taken immediately postburn and at the time of sacrifice six hours later. The most severe burns were associated with the PVC tube. Silica ash was seen in the airway after the silicone tube fires and raises the possibility of future problems with silicosis. Histological examination of the trachea showed acute injury in all of the animals; specimens from the dogs with the PVC tube fires demonstrated the most severe cellular damage.

Hosmer A. Johnson, one of the early laryngologists in the Midwest, graduated in 1852 from Rush Medical College, and was the first intern in Chicago. With four other faculty members he left Rush in 1859 to establish what subsequently became the Northwestern University Medical School. He taught many subjects and was extremely active in local and national societies. An interest in diseases of the chest led him into laryngology and he became a charter member of the American Laryngological Association, where he reported on congenital tumors of the larynx, laryngeal paralysis, and cancer of the larynx. Dr Johnson was a master of six or seven foreign languages, a versatile civic leader, a talented orator, and was greatly admired for his medical skills. The breadth of his accomplishments and character made for a truly memorable life.

Oxidative stress and inflammation are considered major drivers in the pathogenesis of diabetic complications, including renal and cardiovascular disease. A symbiotic relationship also appears to exist between oxidative stress and inflammation. Several emerging therapies target these crucial pathways, to alleviate the burden of the aforementioned diseases. Oxidative stress refers to an imbalance between reactive oxygen species (ROS) and antioxidant defenses, a pathological state which not only leads to direct cellular damage but also an inflammatory cascade that further perpetuates tissue injury. Emerging therapeutic strategies tackle these pathways in a variety of ways, from increasing antioxidant defenses (antioxidants and Nrf2 activators) to reducing ROS production (NADPH oxidase inhibitors and XO inhibitors) or inhibiting the associated inflammatory pathways (NLRP3 inflammasome inhibitors, lipoxins, GLP-1 receptor agonists, and AT-1 receptor antagonists). This review summarizes the mechanisms by which oxidative stress and inflammation contribute to and perpetuate diabetes associated renal and cardiovascular disease along with the therapeutic strategies which target these pathways to provide reno and cardiovascular protection in the setting of diabetes.

AbstractThe authors present a technique using electrocautery diathermy to make surgical tattoos. This method has been used in over 300 patients who underwent head and neck surgery at Aberdeen Royal Infirmary and Albany Medical College, New York, over a period of five years. A wide variety of operative procedures such as total laryngectomies and neck dissections were performed. The electrocautery surgical tattoos have a major advantage of persisting until the end of the operative procedure by which time other types of tattoos have faded. The technique is widely available, inexpensive, and has to date been complication free.
