PNA Highlights May 2023

PNA Spotlight: Dr. William Couldwell

This month the PNA Spotlight focuses on William Couldwell, MD, PhD, who serves as Professor and Chair of the Department of Neurosurgery at the University of Utah. He is also a member of the PNA’s Scientific Advisory Panel. He studied at the University of British Columbia in Vancouver and at Dalhousie University in Halifax, Nova Scotia, majoring in physical chemistry and biology. Dr. Couldwell attended medical school at McGill University in Montreal. He did internship in surgery at the University of Southern California and completed a neurosurgical residency there in 1989. He served as a research fellow in neuroimmunology at the Montreal Neurological Institute and Hospital and research fellow in the neurosurgical service in Lausanne, Switzerland. He returned to U-S-C as an assistant professor of neurological surgery in 1991, where he stayed for four years. Later he became professor and chairman of the Department of Neurological Surgery at New York Medical College, as well as program director of neurosurgical residency in 1997. In 2001 he became professor and chairman of the Department of Neurosurgery at the University of Utah. Dr. Couldwell was kind enough to answer some questions from the PNA. His answers follow.

PNA Medical Corner: Fascia Lata in Reconstructive Neurosurgery

This month the PNA Medical Corner showcases an article co-authored by a member of the PNA, Dr. Varun Kshettry of the Cleveland Clinic. The study concludes that the use of fascia lata in challenging cases of skull base reconstruction is highly effective with few side effects for cases of craniopharyngioma, meningioma and more.

Abstract

Background: Multiple methods exist for skull base reconstruction of defects created by expanded endonasal approaches. While the nasoseptal flap (NSF) has been well established as the workhorse of mucosal reconstruction in complex skull base defects in multi-layered closures, a variety of options exist for the inner layer of multilayer reconstruction, including fascia lata (FL).

Objective: To present our experience and outcomes in utilizing FL in multiple ways to reconstruct a wide variety of complex skull base defects

Study: Cushing’s patients develop cataracts at younger ages

An article in Cushing’s Disease News examines a study published in Graefe’s Archive for Clinical and Experimental Ophthalmology, that finds that Cushing’s patients are at higher risk of developing cataracts at a younger age compared to non-Cushing’s patients. They developed them at an average age of 48.1. Patients with Cushing’s Syndrome “being 34% more likely to develop cataracts than the general population. For those with Cushing’s disease, the risk was 39% higher.” Read more: https://cushingsdiseasenews.com/news/cushings-patients-higher-risk-developing-cataracts-younger-age/
