Cartilage regeneration attempts to restore damaged articular (joint) cartilage. Several techniques have been used for cartilage regeneration. While some of these are being used today, researchers continue to look into new ways to regrow cartilage in an attempt to give people relief from the pain of osteoarthritis. What Is Articular Cartilage? The matrix of cartilage is made up of collagens, proteoglycans, and non-collagenous proteins. While cartilage is a highly-organized structure, about 85% of cartilage is water....

A broken wrist is a common injury. In fact, wrist fractures are the most common extremity fracture, accounting for more than 10% of all fractures of the arms or legs. About 3/4 of all forearm fractures occur on the end of the radius bone – this part of the bone is called the distal radius. One of the most common types of distal radius fractures is called a Colles fracture....

Chocolate has taken the blame for breakouts for decades. But is the bad rap justified? There Is No Evidence That Chocolate Itself Causes Acne It’s good news for all you chocoholics: eating chocolate does not cause pimples. There are no studies linking this sweet treat to the development of acne. There is no evidence that cocoa beans, from which chocolate is made, cause pimples. And while some point to the sugar that also makes up a portion of all chocolate treats, even that evidence is weak....

Definition: Emmetropia is the term used to describe a person’s vision when absolutely no refractive error or de-focus exists. Emmetropia refers to an eye that has no visual defects. Images formed on an emmetropic eye are perfectly focused, clear and precise. Eyes that have emmetropia do not require vision correction. When a person has emmetropia in both eyes, the person is described as having ideal vision. When an eye is emmetropic, light rays coming into the eye from a distance come to perfect focus on the retina....

While you might be worried about documented incidents of coronavirus reinfection making headlines, infectious disease experts are less concerned. Key Takeaways The first documented cases of COVID-19 reinfection shows patients were reinfected with two different versions of the SARS-CoV-2 virus.Viral mutations and variations are a normal part of the life cycle of RNA viruses like SARS-CoV-2. On Monday, a study published in The Lancet Infectious Disease confirmed a 25-year-old Nevada man tested positive for SARS-CoV-2, the viruses that causes COVID-19, on two separate occasions: April 18 and June 5....

It seems to happen every month, like clockwork. Your skin appears to be clearing up nicely when suddenly it begins erupting in breakouts again, just around the time of your period. Could you be imagining it, or is premenstrual acne a real phenomenon? Premenstrual Acne Symptoms Premenstrual acne is a real phenomenon. Premenstrual acne, often dubbed “PMS acne,” is a consistent flare-up or worsening of acne every month, coinciding with the menstrual cycle....

There are many options for the treatment of tennis elbow. Different healthcare providers may recommend different treatments. The reason you may hear these differing recommendations is that there are a lot of options for treatment, and the scientific research is conflicting regarding which is best. What we do know is that most people will get better with time, regardless of what treatment is used to control symptoms. There are several types of injections that have been used for the treatment of tennis elbow, but there is little to suggest that one type of injection is better than any other....

If you have thyroid disease as well as irritable bowel syndrome (IBS), it’s understandable to wonder if there’s a connection between the two. Although there are numerous health problems that IBS patients experience at a higher rate than others, there’s no evidence that having thyroid disease causes IBS or vice versa. That said, thyroid disease can cause similar gastrointestinal symptoms to those of IBS, so it can be easy to conflate them....

Lyme disease, the most common tick-borne illness in the United States, is caused by an infection with the bacteria Borrelia burgdorferi. Infected deer ticks can transmit the disease when they bite people. In the United States, Lyme disease primarily occurs in three geographic regions: the Northeast and Mid-Atlantic states (from Maine to Virginia), the Midwest (Minnesota, Wisconsin, and Michigan), and Northern California. Early treatment is vital to prevent the disease from progressing through later stages....

Marijuana has been considered a possible treatment option for many medical conditions, including migraines. However, at the current time, research hasn’t proven whether marijuana is effective in treating these painful episodes. There is some evidence suggesting that it might help in migraine treatment and prevention, but it isn’t clear if there is a safe or recommended dose, and whether there may be a certain type of migraine that is more likely to improve with cannabis treatment....

Navicular stress fractures are a common foot injury in athletes. These stress fractures tend to occur in athletes whose sport requires explosive movements and sudden changes in direction. Commonly injured athletes include runners, jumpers, sprinters, basketball, and soccer players. Why They Occur The navicular bone is designed with a few problems that make it particularly susceptible to stress injury. One of these problems is the location of the bone. Located in the middle of the foot, high compressive forces are focused on this bone, particularly when the foot strikes the ground....

The winners of the 2021 Nobel Prize in Physiology or Medicine answered a fundamental question about how our bodies respond to temperature and touch by using chili peppers. Key Takeaways The 2021 Nobel Prize in Physiology and Medicine was awarded to scientists David Julius and Ardem Patapoutian. The scientists answered a centuries-old question on how our bodies convert temperature and touch into feelings of pain.Their findings encourage more research on pain and could lead to new treatments of various conditions....

The occipital nerves are a group of nerves that originate in the cervical spine and innervate (energize) the occipital area (the area along the back of the neck, and sides and back of the head). The occipital nerves’ primary function is to deliver sensory information to the skin on the back and side of the scalp and the skin of the external ear. This article examines the anatomy and function of the occipital nerves, symptoms, causes, diagnosis, and treatment of related conditions....

Putting toothpaste on a pimple may seem like an acne home remedy worth trying, but there’s no evidence that it actually works. A number of treatment alternatives, most of them widely available over-the-counter products, are more effective. Toothpaste on a pimple, quite apart from offering no real benefit, may actually cause harm. Some acne treatments share bacteria-killing properties with toothpaste, but they’re two different products designed for separate uses. This article explains why toothpaste is a poor choice for acne treatment, and it explains how toothpaste may cause problems when used on skin....

The Tinetti Balance Assessment Tool is used by physical therapists to assess the quality of a patient’s gait and balance. The Tinetti test can help provide data about the severity of poor balance when standing, walking, and changing directions and is useful to help determine if a patient is at an increased risk of falls. This article discusses the Tinetti test, how it works, and what it is used for....

A variety of medications are frequently used in the hours and days after surgery to control pain. Pain is typically the most severe in the 72 hours after surgery, which, unsurprisingly, is when patients are most likely to receive potent pain relievers. Most medications to relieve pain are given as a pill or intravenously (through an IV). These medications may be a non-steroidal anti-inflammatory (NSAID) in the same drug family as ibuprofen, or they may be an opioid-based narcotic medication, such as morphine....

COVID-19 has been linked to a variety of unusual skin and hair conditions. To add to the list, there are now cases of so-called “COVID nails” in some people who had been sick with the virus. Key Takeaways “COVID nails” (or Beau’s lines) is the appearance of horizontal ridges on the fingernails or toenails.Experts say that while nail changes can happen after recovering from COVID-19, they are not a definitive sign that you had the virus....

High-functioning autism (HFA) is neither an official diagnosis nor is there an agreed-upon definition of what the term means. In the broadest sense of the term, high-functioning autism may mean any of the following: A person with relatively mild symptoms which, despite their mildness, are significant enough to merit an autism spectrum diagnosis A person with autism whose IQ is higher than 70 A person with autism who is successfully navigating a typical school or work environment A person who is able to mask symptoms of autism and can “pass” for neurotypical A person who, at one point, had an Asperger’s syndrome diagnosis—a diagnosis that has not been officially in use since 2013 Adding to the confusion is the fact that many people with autism may be bright and accomplished yet have severe symptoms (such as anxiety and sensory dysfunction) that significantly impact their daily functioning....
