Gerstmann Syndrome samer kareem 2,346 Views • 2 years ago

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.

Spermatocele
Spermatocele samer kareem 26,245 Views • 2 years ago

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.

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.

SPERMATOCELE vs EPIDIDIMAL CYST
SPERMATOCELE vs EPIDIDIMAL CYST samer kareem 3,017 Views • 2 years ago

The epididymis is a long coiled tube that lies above and behind each testicle. The epididymis collects and transports sperm from the testis to the vas deferens (tubes that transport sperm to the urethra). An epididymal cyst is a cyst-like mass in the epididymis that contains clear fluid. Typically, epididymal cysts and spermatoceles do not cause symptoms. When discovered, the epididymal cyst is usually about the size of a pea and feels separate from the top of the testis. Spermatoceles typically arise from the head of the epididymis, and are felt on the top portion of the testicle. Epididymal cysts and spermatoceles are often incidental findings on testicular self-examination or routine physical examination. It is important that any mass noted in the scrotum be examined by a urologist in order to obtain an accurate diagnosis, especially a mass on the testicle itself. Our team in the Division of Urology will typically be able to confirm the diagnosis on physical exam. However, a scrotal ultrasound may also be used in order to rule out other conditions.

How Blood Clots Form
How Blood Clots Form samer kareem 1,859 Views • 2 years ago

A pulmonary embolism (PE) usually happens when a blood clot called a deep vein thrombosis (DVT), often in your leg, travels to your lungs and blocks a blood vessel. That leads to low oxygen levels in your blood. It can damage the lung and other organs and cause heart failure, too. A PE can be life-threatening, so if you've been diagnosed with DVT, you should be aware of this risk. Follow the treatment plan for your DVT to stop the clot from getting bigger and to keep new clots from forming. Symptoms and Diagnosis PE won't always cause symptoms. You might have: Chest pain, which may get worse with a deep breath Sudden shortness of breath or rapid breathing Fast heartbeat Sudden cough Coughing up blood Lightheadedness or fainting Anxiety Call 911 if you notice these symptoms. They could also be symptoms of a heart attack, pneumonia, or other serious problems.

Chest Tube Drainage System
Chest Tube Drainage System samer kareem 3,357 Views • 2 years ago

If you’re like me, you probably hook your chest tube up to a Pleur-Evac, put it on the ground, then back away slowly. Who knows what goes on in that mysterious bubbling white box? Hopefully this will post shed some light. Isn’t this just a container for stuff that comes out of the chest? Why does it look so complicated? It’s complicated because the detection/collection of air and fluid require different setups. Most commercial models also allow you to hook the drainage system to wall suction, so you can quickly evacuate the pleural space. This requires its own setup. Because of the need to juggle air, fluid and suction, the most common commercial system includes 3 distinct chambers. If you were to simplify the device, or build one out of spare bottles and tubes, it might look like this:

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].

Effects Of Alcohol On The Brain samer kareem 12,621 Views • 2 years ago

Alcohol not broken down by the liver goes to the rest of the body, including the brain. Alcohol can affect parts of the brain that control movement, speech, judgment, and memory. These effects lead to the familiar signs of drunkenness: difficulty walking, slurred speech, memory lapses, and impulsive behavior.
