PNA Spotlight: Dr. Adam Mamelak

This month the PNA Spotlight focuses on Dr. Adam Mamelak, a neurosurgeon and co-director of the Pituitary Center at Cedars Sinai Medical Center in Los Angeles. Dr. Mamelak earned his B.A. in Physics at Tufts University and earned his MD from Harvard Medical School. He did a surgical internship and then a residency at the University of California at San Francisco Medical Center. He did a fellowship at the Epilepsy Research Laboratory at UCSF, and another postdoctoral fellowship in neuroscience at the California Institute of Technology & Huntington Medical Research Institutes in Pasadena, California. Dr. Mamelak was kind enough to answer a series of questions from the PNA.

His answers are below:

PNA Medical Corner: New options for imaging MRI-resistant Cushing tumors

The tiny tumors that cause Cushing disease are tough to detect with standard MRI. Fortunately, some new options are available, boosting the chances for successful treatment.

“Sometimes pituitary tumors are so small, they’re nearly impossible to see,” says Mayo Clinic neurosurgeon Dr. Jamie J. Van Gompel. “The success of surgery drops dramatically when we can’t see these tumors on imaging. Anything that tells us where the tumor is will help us determine the risks of surgery and also improve the chances of long-term cure.”

About half the tumors that cause Cushing disease aren’t clearly visible on standard MRI. Standard MRI provides 2D images of relatively large sections of the pituitary, which might not show a tumor that’s only several millimeters in size. Pituitary MRI is also prone to visual flaws or artifacts.

“It’s hard for MRI to image tissue that’s near air. And the pituitary always has air next to it, from the sinuses,” explains Mayo Clinic neuroradiologist Dr. Ian T. Mark.

    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/
