A woman in her 20s with syncope
Written by Destiny Folk MD, with edits by Meyers, peer reviewed by Smith and GrauerA woman in her late 20s with a past medical history of cervical cancer status post chemotherapy and radiation therapy presented to the emergency department for shortness of breath, chest tightness, and two episodes of syncope.Her initial vital signs revealed a temp of 97.7F, HR 125, RR 20, BP 115/90, and an oxygen saturation of 95% on room air. Upon arrival, she did not appear in acute distress. She was noted to be tachycardic and her heart sounds were distant on physical exam. She had a normal respiratory effort, and her lungs were clear to...

What type of devices should a person with a pacemaker be cautious about? Cardiology Basics
Artificial pacemakers are cardiac implantable electronic devices (CIED) which give tiny electrical signals to the heart when the heart’s own pacemaker is not functioning well. Sinus node is the natural pacemaker of the heart, located in the upper part of right atrium near the orifice of superior vena cava.
Pacemakers may also be used when the impulses from the sinus node are not conducted well to the ventricles in complete atrioventricular block. Pacing for bradycardia can be with single chamber or dual chamber pacemakers, depending on the indication for pacing. Dual chamber pacemakers are AV sequential pacemakers which...

Wireless Sensor Measures Deep Tissue Oxygen Levels
Researchers at the University of California, Berkeley have developed an ultrasound-powered implantable sensor that can measure oxygen levels in tissues deep within the body and transmit these data to an external device. The technology could be useful...

The Future of Value-Based Care Relies Upon Providers: Taking the Reins on Alternative Payment Models
By CHUCK SAUNDERS and NEAL SHORE, MD
2017 was a pivotal year for the growth of value-based care. For many practices, this meant completing their first performance year as part of the Merit-Based Incentive Payment System (MIPS). A much smaller percentage of practices was able to participate in approved advanced Alternative Payment Models (APMs).
While practices await feedback on their 2017 performance, early lessons have already become evident. Clearly, as practices are assigned greater responsibility and accountability for patient populations, it becomes increasingly important that they effectively navigate the reimburseme...

Ablation of ventricular tachycardia by sterotactic radiation therapy
Till date, ablation of ventricular tachycardia is done by invasive catheter based mapping of arrhythmia focus within the ventricles. In a potentially path breaking report published in the New Enland Journal of Medicine, non invasive cardiac radiation for ablation of ventricular tachycardia in 5 patients has been described [1]. Ventricular tachycardia was induced by the already implanted cardioverter-defibrillator (ICD) and non invasive electrocardiographic imaging of the tachycardia obtained. Stereotactic body radiation therapy (SBRT) was done after standard simulation, planning and treatment procols. Treatment efficacy...

Giving Cancer Hell
ANISH KOKA, MD
There are 80,000 new cases of primary brain tumors diagnosed every year in the United States. About 26,000 of these cases are of the malignant variety – and John McCain unfortunately joined their ranks last week. In cancer, fate is defined by cell type, and the adage is of particular relevance here.
Cancer is akin to a mutiny arising within the body, formed of regular every day cells that have forgotten the purpose they were born with. In the case of brain tumors, the mutinous cell frequently happens to not be the brain cell, but rather the lowly astrocyte that normally forms a matrix of support f...

Fight Aging! Newsletter, June 20th 2016
We examined the engraftment and differentiation of alkaline phosphatase-positive NSCs expanded from the postnatal subventricular zone (SVZ), 3 months after grafting into the intact young or aged rat hippocampus. Graft-derived cells engrafted robustly into both young and aged hippocampi. Although most graft-derived cells pervasively migrated into different hippocampal layers, the graft cores endured and contained graft-derived neurons.
The results demonstrate that advanced age of the host at the time of grafting has no major adverse effects on engraftment, migration, and differentiation of grafted subventricular zone...

Wisdom…
…the quality of having experience, knowledge, and good judgment.
I read today a collection of words that exude wisdom. I share it with you because the purpose of this blog is to do create value through education.
Peggy Girshman was an award-winning health journalist. When ill with a life-limiting illness, she wrote her own eulogy. NPR published it today after her death.
Must-read is an overused phrase, but it modifies perfectly her words. Here are a few excerpts, with my thoughts.
Work-Life Balance: Though Girshman wished she could have worked longer, “to convince someone I was right,” she also wished she...

12 Percent of People Will Be Diagnosed With This Life-Threatening Heart Disease
The post below first appeared on HuffPost Healthy Living on April 20.
Jen Hyde, a 30-year-old poet and artist living in Brooklyn, has a congenital heart defect. By the age of 25, Hyde had two open-heart surgeries, including a heart valve replacement.
“I know that heart disease is the number one killer of women in America,” Hyde said. “I’m currently in great shape, but part of staying this way means building a strong relationship with my cardiologist so that the care I receive is preventative, not reactive.”
Hyde is not alone in suffering from heart health issues — in the U.S., cardiovascular disease is the No...

Healthcare Update Satellite — 11-14-2013
See more news from around the web over at my other blog at DrWhitecoat.com
An example of the downside to government-run health care. Patients in Venezuela can’t get proper medical care. 300 cancer patients were just sent home when supply shortages and “overtaxed equipment” made it “impossible … to perform non-emergency surgeries.” 70% of the radiation therapy machines are inoperable. Basic supplies such as needles, syringes, medications, operating room equipment, X-ray film, and blood needed for transfusions are all in short supply. There is no anesthesia for elective surgery. Patients can no longer get organ d...
