Bird flu shuffle probes viral compatibility

The good news is that packaging signals on the H5 and H7 viral RNA genomes are often incompatible with the H3N2 viruses. But mix and match still occurred at a low level, particularly with Read more

A life consumed by sleep

Nothing he tried had worked. For Sigurjon Jakobsson, the trip to Atlanta with his family was a last-ditch effort to wake up. He had struggled with sleeping excessively for several years before coming from Iceland to see a visionary neurologist, who might have answers.

Three remarkable Emory case reports from #ACC17

The big news from the American College of Cardiology meeting today is about PCSK9 inhibitors, which were known to be effective at lowering LDL cholesterol, and how much they really prevent heart attacks and save lives.

Lab Land went looking off the beaten path for individual stories of Emory cardiologists saving lives and was pleased to find several. We highlight here three remarkable case reports that are being presented at the ACC meeting. We look forward to learning more about these cases.

Refractory electrical storm 

Electrical storm is life threatening and refers to a recurrent arrhythmia. The arrhythmia did not respond to drug treatment, so anesthesiologists were brought in to perform left stellate ganglion block, an injection of medication into a nerve bundle in the neck, allowing diagnosis and further treatment. It turns out the arrhythmia was caused by sarcoidosis, a rare intrusion of immune cells into the heart. [Saturday morning: Michael Lloyd, Boris Spektor]

A 30-year old woman came to doctors with drastically impaired heart function, although she did not have a blockage of her coronary arteries or signs of damage to the heart muscle.

Giving birth unveils birth defects

Ten days after giving birth, a woman came to a hospital with chest pain. Upon cardiac catheterization, a rearrangement of her coronary arteries was discovered. It appears that the congenital defect had gone undetected until the stress of giving birth. Under medical treatment, she is asymptomatic, but she will need future monitoring and possibly a procedure to correct the artery problems. [Sunday morning: Camden Hebson]
