Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

pituitary tumors

Pituitary tumors removed using a 3-D endoscope

Although the size of a pea, the pituitary gland, located deep within the skull at the base of the brain, is indispensible.

Known as the master gland, it directs other glands to produce hormones that affect metabolism, blood pressure, sexuality, reproduction, and development and growth, as well as other bodily functions.

So when something goes wrong with the pituitary, such as the development of a tumor, the consequences can be serious, even life threatening. Relatively common, pituitary tumors initially can be difficult to diagnose and, once found, difficult to remove because they are surrounded by so many nerves, such as those that supply the eye with movement and vision and blood vessels that supply the brain with blood.

Emory’s Pituitary Center is one of a handful of medical centers across the country using the latest 3-D endoscope for removal of pituitary tumors, a delicate and precise procedure. Having the new 3-D endoscope is a tremendous aid for a surgeon when operating on a small organ at the base of the brain, says Emory neurosurgeon Nelson Oyesiku, MD, PhD.
