What you have is called a subungual hematoma; that's just a fancy way of saying a collection of blood under the nail. It may happen with any kind of direct trauma, including (perhaps the worst?) a broken toe. It is similar to any other injury causing bleeding; the major difference is you can actually see the dark blood because the nail is transparent. Yes, ...

First off, she would be killed instantly. There wouldn't be any question of what might kill her "ultimately" because ultimately would be the moment she hit the ground. Yes, there have been people who survived falls from much greater heights, with the record holder being Vesna Vulović, a Serbian flight attendant who fell 10,160 m (33,330 ft), but those are ...

There are a few different types of injury to the skin. You can have a contusion (Bruise), abrasion (scrape), puncture, laceration or incision. The injury that you suffered is a laceration, as opposed to an incision. The main difference between the two is the cleanliness of the edges, lacerations are more jagged, incisions are clean slices. There's a few ...

H = IxIxR Where H is the amount of heat produced when a current of I is flown through a conductor of resistance R. The resistance of human body may be as high as 100,000 ohms. An average bolt produces current of 30kA. If a typical lightning were to pass completely through a human body (even though this is not the case), the heat energy liberated will be ...

It's much the same as any other traumatic impact, it's a collection of blood from ruptured vessels. In the skin, it appears as a bruise. When under the nail, it appears as a black shape, usually a crescent. If the amount of blood is significant, or if the pressure of it causes pain, you should have it checked out by a podiatrist. It is also possible that if ...

It was an assessment of your mental status. It's usually among the first questions an EMT will ask. The purpose is to determine if your are mentally alert and oriented. The reasons for this assessment are to look for possible brain injury (concussion or worse) and also other causes such as intoxication with alcohol or drugs, low blood sugar, and other ...

There is some weak evidence that high intake of fish high in omega-3 fatty acids EPA and DHA (salmon, mackerel, roe, anchovies, tuna, herring, sablefish, sardines) or fish oil capsules might delay wound healing. Here is one experiment about wound healing in rats fed with fish oil: Detrimental effects of an omega-3 fatty acid-enriched diet on wound healing (...

The skin has 2 layers: epidermis (the outer) and dermis (the inner). Sliding down the rope may cause an abrasion in which only the epidermis is damaged. Scars develop only when the dermis is damaged. Fingerprints (Britannica): Each ridge of the epidermis (outer skin) is dotted with sweat pores for its entire length and is anchored to the dermis (inner ...

I agree with @Carey Gregory's answer. I can tell you how a man falling only 30 feet landing on his back on concrete died. A 30 year old male working on the underside (?) of a bridge, unsecured, fell as above. There were no obvious external injuries. The skull was intact, etc. He arrived by ambulance unconscious and without a pulse. Advanced Trauma Life ...

Putting your fingers in a wound is going to inflict severe pain on the casualty. There are ways you can apply direct pressure on an arterial wound, even if it is on the upper thigh. It is possible to apply pressure to any sort of external bleeding, and sticking your finger inside an arterial wound is not really going to help. The casualty might survive the ...

Under no circumstances should you ever allow chiropractic manipulation of the neck unless you're interested causing a stroke or paralysis. There is an artery that exits between two cervical vertebrae. If it gets pinched off, it can cause a full-blown stroke, and over-manipulation can actually break the neck.

An accident left Derek Amato with a severe concussion and a surprising ability to play the piano. One theory is that his brain reorganized, making accessible existing memories of music. Another is that his brain no longer filters sensory input, enabling him to hear individual notes rather than melodies. http://www.popsci.com/science/article/2013-02/when-...

Is this what you mean? If so, then yes, it is a blister. Wikipedia entry on blister explains what it is. The clear liquid is blood plasma. It is there to prevent further damage to the tissue and cells, which in your case is the pinch-crushing door. Quoting Wikipedia, This plasma solution helps new cells divide and grow into new connective tissues and ...

I took a quick look at the National Registry site, and their practice tests still show protocols and usage questions for backboard application, so if it is a new national EMS policy, then it isn't showing on the tests. However, I was able to find a couple of articles on EMSWorld and on JEMS (Journal of Emergency Medical Services) citing current research ...

One word: dehydration. You spent a day out in the sun, exerting yourself, and probably didn't maintain your normal level of hydration. Consequently, you're mildly dehydrated (or, more properly, hypohydrated). Dehydration means a lower blood volume, which in turn means your heart has to beat faster to move the same volume of blood. Consequently, your heart ...

Shock is a specific condition with a number of different causes. However the rest, when used in the general parlance are subjective descriptions of the severity of a person's condition, and they generally don't have a specific definition. For some, it describes the severity of the diagnosis (eg how bad the injuries are or how far along a disease has ...

In addition to the above answer that provides guidance on some things to take into consideration when discussing this with your doctor/therapist, I will recommend how to approach seeking the right provider. First, you've seen "GPs, Physiotherapists and Physical therapists" - but have you seen an orthopedic surgeon or non-surgical orthopedic physician? This ...

There is only marginal evidence of RICE (rest, ice, elevation and compression) improving recovery in injuries. For example, in a review of 22 studies of ankle injuries, ice and elevation had only marginal effects on recovery. In another review of six studies in soft tissue injuries, there was no evidence that ice was effective. In a review of 45 sports ...

Examples of accidents in which the described injuries can occur: Falling from the height (>4 m) on the hard surface, especially when trying to ease the impact with the hands (Here's one military report of parachuting accidents with detailed list of injuries in Table 4) Falling down a steep slope, such as in the mountains, and hitting rocks on the way down ...

Bones and tendons take quite a long time to condition due to pressure. Generally the remodelling you do see see happens over a prolonged period of time. The sort you see most frequently is in athletes, power lifters and body builders. That would be remodelling that is not associated with trauma, but with conditioning. When you investigate the bones (in an ...

The answer is hypertrophy, but if the injury is disabling, then it will lead to muscle atrophy due to disuse. Note that body builders lift weight until causing minor injury. https://www.unm.edu/~lkravitz/Article%20folder/musclesgrowLK.html

As the OP has verified in the comments, the injury is in fact called an abrasion. Quick Overview Abrasion is a wound caused by rubbing or scraping the skin or a mucous membrane; a “skinned knee” and a “floor burn” are common examples. To treat the injury, the wound should be washed, a mild antiseptic or antibiotic ointment applied, and the wound covered ...

I think you are discussing about ABRASION...it's what called the injury caused by rubbing over rough surfaces with your skin peeled off..search images for abrasion to confirm it.Also look for CONTUSION.Most probably it must be abrasion from your words.

Though most people do get surgery to reconstruct their torn ACL, it is possible to regain full ability of your knee without surgery. Just through rehabilitation, you can totally recover from a torn ACL. In a clinical trial done in 2010,1 two different treatment strategies were given to 121 young, active adults (ages 18-35) who suffered acute ACL injuries. ...

I will not get into the possible association between your symptoms and treadmill or any possible etiologies regarding your symptoms. However, I am fairly certain that your numbness has nothing to do with your accident. When we are considering symptoms in limb and possible spinal injury the pathophysiology would be some kind of nerve or medullar compression ...
