Narcolepsy samer kareem 10,819 Views • 3 years ago

Narcolepsy is a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. People with narcolepsy often find it difficult to stay awake for long periods of time, regardless of the circumstances. Narcolepsy can cause serious disruptions in your daily routine. Sometimes, narcolepsy can be accompanied by a sudden loss of muscle tone (cataplexy) that leads to weakness and loss of muscle control. Cataplexy is often triggered by a strong emotion, most commonly laughter. Narcolepsy is a chronic condition for which there's no cure. However, medications and lifestyle changes can help you manage the symptoms. Support from others — family, friends, employer, teachers — can help you cope with narcolepsy.

Complex Regional Pain Syndrome samer kareem 7,817 Views • 3 years ago

This syndrome was previously known as reflex sympathetic dystrophy, algodystrophy, causalgia, Sudeck atrophy, transient osteoporosis, and acute atrophy of bone. Usually occurring after an injury, CRPS presents with pain out of proportion to the injury, temperature change, edema, and abnormal skin color. Type I CRPS (90% of CRPS cases) occurs without a definable nerve lesion, while type II occurs with a definable nerve lesion. The pathogenesis is likely due to an injury causing increased sensitivity to sympathetic nerves, an abnormal response to and sensation of pain, and increased neuropeptide release causing burning pain to light touch (allodynia).

Avoid knee replacement surgery with new implant samer kareem 1,144 Views • 3 years ago

Some of these advancements include the use of robots to perform the surgery and the use of computer mapping scanners and software and even 3D printers to make the artificial knee implant. We are also seeing a lot of different advances being made by the medical device manufacturers.Some of these changes are designed to make the devices more durable than the 10 to 20 years they are currently rated to last. This is important when younger patients who are years away from being considered elderly have a total knee replacement, they will typically need another artificial knee implanted at a later date since they are likely to outlive the implant, which doesn’t always happen with elderly patients.
