(VLOG) NeuroOp Guru: Can A Dead Nerve Swell?

Andrew G. Lee, MD, and Drew Carey, MD, return for this latest episode of the NeuroOp Guru to discuss whether a dead nerve can swell, focusing on the condition of papilledema caused by elevated intracranial pressure.

This latest episode of the NeuroOp Guru—hosted by Andrew G. Lee, MD, from Houston Methodist, and joined by Drew Carey, MD, from Johns Hopkins University—explores whether atrophic optic nerves can exhibit swelling or thickening in patients with recurrent papilledema. Carey explains that papilledema can be due to various conditions, including idiopathic intracranial hypertension, hydrocephalus, or brain tumors, and that recurrent headaches may indicate increased pressure. A retrospective study1 of 165 patients with papilledema found that 63% experienced at least one relapse, with 50% showing recurrent papilledema. OCT scans were crucial in detecting these relapses, even in atrophic nerves, suggesting that OCT remains a valuable tool in monitoring neurological conditions. Carey stresses the importance of OCT in detecting intracranial pressure changes in atrophic nerves, contrasting it with glaucoma management. The episode concludes with a proposed revised adage: "A dead nerve can't swell, but it can thicken."

    Dyspnea (Shortness of Breath): Causes, Symptoms & Treatment - my.clevelandclinic.org

    Image
    Overview Shortness of breath (dyspnea) is most commonly caused by heart or lung conditions. Other causes include anemia, anxiety, lack of exercise or living with obesity. What is dyspnea (shortness of breath)? Dyspnea (pronounced "DISP-nee-uh") is the word healthcare providers use for feeling short of breath. You might describe it as not being able to get enough air ("air hunger"), chest tightness or working harder to breathe. Shortness of breath is often a symptom of heart and lung problems. But it can also be a sign of other conditions like asthma, allergies or anxiety. Intense exercise or having a cold can also make you feel breathless. What are paroxysmal nocturnal dyspnea (PND) and sighing dyspnea? Paroxysmal nocturnal dyspnea (PND) is a feeling like you can't breathe an hour or two after falling asleep. Sighing dyspnea is when you sigh a lot after taking deep breaths in to try to relieve the feeling of dyspnea. What is the differ...

These clots typically begin in the leg and then break free and travel to the lung. The American Lung Association estimates that about 1 in 1,000 people in the United States experience a PE each year. A PE can be a serious or life threatening condition, which means receiving prompt medical treatment is vital. Treatment of a PE focus...

    Epoprostenol Via High-Flow Nasal Cannula Improves Severe Hypoxemia in PH - Pulmonology Advisor Epoprostenol Via High-Flow Nasal Cannula Improves Severe Hypoxemia in PH - Pulmonology Advisor Posted: 11 Jul 2019 12:00 AM PDT For patients with severe hypoxemia with pulmonary hypertension or right heart dysfunction, inhaled epoprostenol through high-flow nasal cannula increases oxygenation, according to a study published in Pharmaceutics . The researchers of this retrospective study assessed the effect of inhaled epoprostenol using a high-flow nasal cannula on oxygenation and future mechanical ventilation in patients with hypoxemia comorbid with pulmonary hypertension or right heart dysfunction in an intensive care unit setting. A chart review was completed on adult patients who were admitted into the respiratory care department of the Rush University Medical Center for severe hypoxemia between July 2015 and April 2018 and treated with inha...
