Medulloblastoma Brain Tumor Surgery
Medulloblastoma Brain Tumor Surgery samer kareem 2,624 Views • 3 years ago

Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The most common symptoms of medulloblastoma include behavioral changes, changes in appetite, symptoms of increased pressure on the brain (eg, headache, nausea, vomiting, and drowsiness, as well as problems with coordination). Unusual eye movements may also occur. Like many tumor types, the exact cause of medulloblastoma is not known. However, scientists are making significant strides in understanding its biology. Changes have been identified in genes and chromosomes (the cell’s DNA blueprints) that may play a role in the development of this tumor. There are also a few rare, genetic health syndromes that are associated with increased risk for developing this tumor.

Rotator Cuff Tears
Rotator Cuff Tears samer kareem 1,529 Views • 3 years ago

A rotator cuff tear is a common injury, especially in sports like baseball or tennis, or in jobs like painting or cleaning windows. It usually happens over time from normal wear and tear, or if you repeat the same arm motion over and over. But it also can happen suddenly if you fall on your arm or lift something heavy. Your rotator cuff is a group of four muscles and tendons that stabilize your shoulder joint and let you lift and rotate your arms. There are two kinds of rotator cuff tears. A partial tear is when the tendon that protects the top of your shoulder is frayed or damaged. The other is a complete tear. That’s one that goes all the way through the tendon or pulls the tendon off the bone.

Management of COPD
Management of COPD samer kareem 2,018 Views • 3 years ago

The goal of COPD management is to improve a patient’s functional status and quality of life by preserving optimal lung function, improving symptoms, and preventing the recurrence of exacerbations. Currently, no treatments aside from lung transplantation have been shown to significantly improve lung function or decrease mortality; however, oxygen therapy (when appropriate) and smoking cessation may reduce mortality. Once the diagnosis of COPD is established, it is important to educate the patient about the disease and to encourage his or her active participation in therapy.

Tooth Filling Procedure
Tooth Filling Procedure samer kareem 6,805 Views • 3 years ago

A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).

Spinal cord injury. Symptoms
Spinal cord injury. Symptoms samer kareem 3,668 Views • 3 years ago

Though you might think of your spinal cord as one single piece, it's actually a column of nerves protected by a sheath of myelin and then further secured by 31 butterfly-shaped vertebrae (singular: vertebra). Medical providers divide the spinal cord into four distinct regions. Knowing the region in which the injury is located is often the key to understanding diagnosis and treatment. The four spinal cord regions are: The cervical spinal cord: This is the topmost portion of the spinal cord, where the brain connects to the spinal cord, and the neck connects to the back. This region consists of eight vertebrae, commonly referred to as C1-C8. All spinal cord numbers are descending, so C1 is the highest vertebra, while C8 is the lowest in this region. The thoracic spinal cord: This section forms the middle of the spinal cord, containing twelve vertebrae numbered T1-T12.
