Shoulder Nerve injury
Shoulder Nerve injury samer kareem 2,986 Views • 3 years ago

The shoulder and arm receives its nerve supply through the brachial plexus. The brachial plexus is a complex network of nerves which come out of the neck, passes down to the front of the shoulder and then splits into many separate nerves to travel to different muscles and parts of the skin. Normally an arm movement is produced by initially thinking of the movement, then a message passes from the brain, down through the spinal cord to the appropriate nerve. Then the instruction to move is conveyed along the nerve to the specific arm muscle which then contracts and moves the arm.

Difference between arteriosclerosis and atherosclerosis
Difference between arteriosclerosis and atherosclerosis samer kareem 1,859 Views • 3 years ago

Arteriosclerosis occurs when the blood vessels that carry oxygen and nutrients from your heart to the rest of your body (arteries) become thick and stiff — sometimes restricting blood flow to your organs and tissues. Healthy arteries are flexible and elastic, but over time, the walls in your arteries can harden, a condition commonly called hardening of the arteries. Atherosclerosis is a specific type of arteriosclerosis, but the terms are sometimes used interchangeably. Atherosclerosis refers to the buildup of fats, cholesterol and other substances in and on your artery walls (plaques), which can restrict blood flow. These plaques can burst, triggering a blood clot. Although atherosclerosis is often considered a heart problem, it can affect arteries anywhere in your body. Atherosclerosis may be preventable and is treatable.

Ultrasound Guided Lumbar Puncture Procedure
Ultrasound Guided Lumbar Puncture Procedure samer kareem 3,132 Views • 3 years ago

Lumbar puncture is a common emergency department procedure used to obtain information about the cerebrospinal fluid (CSF) for diagnostic and, less commonly, therapeutic reasons. Please refer to the full article on Lumbar Puncture for more details on the lumbar puncture procedure. Lumbar puncture is typically performed via “blind” surface landmark guidance. The surface landmark technique is reported to be successful in a high percentage of attempted lumbar punctures; however, surface landmark identification of underlying structures has been shown to be accurate only 30% of the time. [1] Unsuccessful identification of proper landmarks often leads to increased difficulty in obtaining CSF, if the procedure is performed, and a higher rate of complications. Few alternatives are available in these cases. If available, fluoroscopic-guided lumbar puncture may be performed. If not, treatment is sometimes initiated empirically without obtaining CSF. Disadvantages of using fluoroscopy include limited availability or necessary transport of the patient outside of the emergency department, inability to directly visualize the spinal canal, and inherent radiation exposure

Worst Nail Infections
Worst Nail Infections samer kareem 2,981 Views • 3 years ago

Paronychias are most often caused by common skin bacteria (most commonly staphylococci bacteria) entering the skin around the nail that has been damaged by trauma, such as nail biting, finger sucking, dishwashing, or chemical irritants. Fungal infection also can be a cause of paronychia formation and should be considered especially in people with recurrent infection. Paronychia should not be confused with herpetic whitlow, which can form tiny pustules on the finger and is caused by a virus but is not typically located at the nail edge. Herpetic whitlow is not treated with an incision and drainage and therefore needs to be distinguished from a paronychia.
