Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing.
Giant cell tumour is a locally aggressive primary bone tumour, located eccentrically in the metaphysis and epiphysis of a long bone. It commonly affects distal end of Femur, proximal end of Tibia and distal end of Radius. It is occasionally reported in small bones of hand and foot[1], spine[2] and pelvis[3]. Though it occurs in 20 - 35 year old individuals commonly, it can also be seen in children as young as 2 years[4] and also in older individuals
Usually a sebaceous cyst grows very slowly and doesn't cause pain. However, they can become inflamed or infected, with the overlying skin becoming red, tender, and sore. Sometimes, they occur on a site that is constantly irritated, such as a cyst on your neck that rubs against your collar.
Very small currents can be imperceptible. Larger current passing through the body may make it impossible for a shock victim to let go of an energized object. Still larger currents can cause fibrillation of the heart and damage to tissues. Death caused by an electric shock is called electrocution.
Testing for the four features of Gerstmann Syndrome in this patient with two separate left sided strokes (left frontoparietal ischaemic stroke followed by left posterior parietal haemorrhagic stroke). He exhibits (i) acalculia, (ii) agraphia, (iii) left-right disorientation, and (iv) finger agnosia. Complicating the issue is his obvious nonfluent aphasia (expressive dysphasia) with paraphasic errors (replacing words with associated words (e.g. says 'fork' instead of 'spoon')) and some comprehension issues.
A spermatocele (SPUR-muh-toe-seel) is an abnormal sac (cyst) that develops in the epididymis — the small, coiled tube located on the upper testicle that collects and transports sperm. Noncancerous and generally painless, a spermatocele usually is filled with milky or clear fluid that might contain sperm. The exact cause of spermatoceles is unknown but might be due to a blockage in one of the tubes that transports sperm. Spermatoceles, sometimes called spermatic cysts, are common. They typically don't reduce fertility or require treatment. If a spermatocele grows large enough to cause discomfort, your doctor might suggest surgery.
