We still do not have high-quality, clinically relevant information to support the use of vasopressin, steroid, and epinephrine (VSE) protocol in patients with IHCA. That does not mean VSE should never be used and it will depend also on the clinicians’ judgment - Dr. Wm. Ken Milne

Vasopressor Extravasation

Depending on the size of the extravasation, bring 5 to 10 mg of phentolamine to the bedside. This will need to be reconstituted, and further diluted to 0.5 mg/mL in normal saline - Pharmacy Joe

Vasopressors

Norepinephrine has been studied the most, so it has both the most and the strongest evidence for its use. This has led to it becoming the most common first-line vasopressor. It is important to remember that this has happened because norepinephrine has fewer side effects than epinephrine or dopamine, not because more patients survive when it’s administered - Jonathan Lee

Vasovagal Syncope

Vasovagal syncope or neurocardiogenic syncope (NCS) is caused by a drop in blood pressure, quickly followed by faster then slower heart rate resulting in poor blood and oxygen flow to the brain which results in temporary loss of consciousness - Marc D. Le Gras MD.

The past decade has witnessed a large body of research outcome focusing on Vitamin K2 metabolism, and it’s benefits for bone health and vascular health, in addition to suppression of chronic inflammatory factors - Dr. Neville Wilson

Vitamin Water

The way that vitaminwater is marketed and positioned it’s made to look more healthful than other sugary beverages, but it’s not – it’s still just a soft drink - Margo G. Wootan

Vitamins

Vitamin supplementation, except for vitamin D, does not reproduce the protective effect of natural food stuffs. So, why do we persist on taking them - HWN

Vitamins Which Ones Should We Take

Have you taken your vitamins today? But are they really necessary or a waste of your hard earned money. A healthy, balanced diet may be all you really need!

Vitiligo

Even as scientists celebrate progress in the lab, a stigma-busting movement asserts that those with the autoimmune skin condition are more in need of acceptance than medicine - Elie Dolgin

Vitreous Detachment

Posterior vitreous detachment doesn’t need to be treated. While the floater is initially annoying, with time it becomes less noticeable to the patient - KevinMD.com

Vitreous Hemorrhage

See an eye doctor within 24 to 48 hours if you have a new floater, experience a sudden “storm” of floaters, see a gray curtain or shadow move across your field of vision, or have a sudden decrease in vision - Roni Caryn Rabin

Vivitrol

Vivitrol is all the rage amid a brutal opioid epidemic. But it may also make it almost impossible to feel pleasure—and raise the risk of fatal overdose after relapse - Maia Szalavitz

VKA

Warfarin is the drug the medical community loves to hate - Eric Topol

VLDL

It transports triglycerides (with fatty acids) to the muscles and fat tissue, where they are deposited. In return, VLDL takes up cholesterol from the tissues. As it loses triglycerides, VLDL becomes LDL – a particle rich in cholesterol and low in triglycerides - Biljana Novkovic PhD

VNS

Vagus nerve stimulation (VNS) has already been approved for refractory epilepsy and depression. But the therapeutic reach of this cranial nerve covers a roster of stress-related maladies - Paul Spector MD

VO2max

If you could pick one measure to evaluate your health, what would you pick? Blood pressure? Cholesterol? These are commonly measured by your GP, but there is something that is more informative: maximal aerobic capacity, otherwise known as VO₂max - Richard Metcalfe

Vocal Cord Dysfunction

Patients with VCD (or other upper airway problems) often present with easily audible stridor and/or expiratory wheeze. This is often very dramatic and scary. Alternatively, in patients with severe asthma this shouldn't be audible from across the room. In fact, patients with severe asthma may have a totally quiet chest (even with a stethoscope) - Josh Farkas

VOCs

Volatile organic compounds (VOCs) are chemicals that both vaporize into air and dissolve in water. VOCs are pervasive in daily life, because they’re used in industry, agriculture, transportation, and day-to-day activities around the home - Bruce Lindsey

Voice Box

For vocal cords, producing sound is no mean feat. They need to be flexible enough to vibrate, but tough enough to withstand smacking together over a hundred times per second. If our whole bodies were subjected to an equivalent force, we’d be ripped apart - Eric Broodman

Voice Recognition

Voice recognition in healthcare is one of the industry's most exciting and promising development trends - DeepScribe

Volcanic Eruptions

Sometimes knowing more about the world around us makes us feel more in control of our lives and survival & sometimes knowing more only underscores how small and helpless we are compared to the forces of nature on the angry rock - Grace Donnelly

Volleyball

There are six people around the court and it's literally like a ballet. And fundamentals are at the core of everything you do - Caren Kemner

Volvulus

Volvulus is the third most common cause of large bowel obstruction, following cancer and diverticulitis. Volvulus accounts for less than 10% of colonic obstructions. The sigmoid colon is mostly commonly affected, followed by the cecum - Frank H. Miller

Vomiting

One of the best temporary cures for pride and affectation is seasickness; a man who wants to vomit never puts on airs - Josh Billings

Vomiting & Marijuana

Its three primary symptoms are nausea, abdominal pains and cyclical vomiting, an ailment where you retch or throw up far more often than you should (around six to 12 times an hour) - Jake Lewis

Von Hippel-Lindau Syndrome

Von Hippel-Lindau disease (VHL) is a rare, genetic multi-system disorder in which non-cancerous tumors grow in certain parts of the body - NINDS

Von Recklinghausen’s Disease (Neurofibromatosis 1)

Neurofibromatosis, commonly called Nf, is five times more common than Muscular Dystrophy. And yet–partly because the condition has so many disparate effects, and partly because of its cumbersome name–it has a very low public profile - Simon Callow

Von Willebrand Disease

Amazingly, it is remarkably common – if not well understood – and by some estimates, affects as many as 1 in 100 people...Most cases, though, go undiagnosed because the symptoms tend to be very mild - Jane Wilkens Michael

VR

Virtual reality is on track to change healthcare as we know it, to modernize training, speed rehabilitation, mitigate phobias, improve doctor-to-patient empathy, and enable virtual medicine - Eric Williams MFA

VSDs are completely treatable. The prognosis of a patient with VSD is great. Spontaneous closure of the VSD is common in patients with small to moderate holes. Clinical outcome associated with VSD closure is excellent, with almost zero surgical mortality rate - Upasana Roy Chaudhary

VT

Treat for VT, sort it out later. VT is the rhythm that will kill your patient first, not SVT with aberrancy - Blake Briggs MD

Vulvar Cancer

Every woman I talk to has no clue what this is - Susan Golden

Vulvodynia

Vulvodynia is a diagnosis made after you’ve excluded everything - Dr Winston de Mello

VWD

Amazingly, it is remarkably common – if not well understood – and by some estimates, affects as many as 1 in 100 people...Most cases, though, go undiagnosed because the symptoms tend to be very mild - Jane Wilkens Michael

VX Nerve Agent

Unlike the nerve agent sarin, which was used to attack the Tokyo subway and Ghouta, a suburb of Damascus in Syria, the V-series are termed “persistent” agents - Martin Boland

Vyvanse

As a prodrug, with its amphetamine component tied to an amino acid molecule, Vyvanse only has bioavailability if swallowed - Tom Hawking
