Transposition of the Great Arteries
Transposition of the Great Arteries samer kareem 7,689 بازدیدها • پیش 3 سال ها

Transposition of the great arteries is a serious but rare heart defect present at birth (congenital), in which the two main arteries leaving the heart are reversed (transposed). Transposition of the great arteries changes the way blood circulates through the body, leaving a shortage of oxygen in blood flowing from the heart to the rest of the body. Without an adequate supply of oxygen-rich blood, the body can't function properly and your child faces serious complications or death without treatment.

Marfan Syndrome Diagnosis and Treatment
Marfan Syndrome Diagnosis and Treatment samer kareem 9,843 بازدیدها • پیش 3 سال ها

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.

Bone Tumor. Reasons
Bone Tumor. Reasons samer kareem 5,827 بازدیدها • پیش 3 سال ها

Bone tumors develop when cells in the bone divide without control, forming a mass of tissue. Most bone tumors are benign, which means they are not cancer and cannot spread. However, they may still weaken bone and lead to fractures or cause other problems. Bone cancer destroys normal bone tissue and may spread to other parts of the body (called metastasis). Benign Bone Tumors Benign tumors are more common than malignant tumors of the bones. These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. It is more common in people under age 20. Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s. Osteoblastoma is a single tumor that occurs in the spine and long bones, mostly in young adults. Enchondroma usually appears in bones of the hand and feet. It often has no symptoms. It is the most common type of hand tumor.

💥Patellar Tendon Pain AKA “Jumper’s Knee”👇

💥If you have this, it’s likely because your patellar tendon was over-stressed beyond what it can currently handle (due to loads that are too high or lack of recovery).

🔑 Try 5 reps of 45 second holds
🔑 2 min of rest in between each rep
🔑 Keep your knees at roughly 60 deg angle
🔑 7/10 intensity
🔑Should not increase pain during or after exercise

📚A research article found that this protocol using a knee extension machine provided significant short term pain relief. Most people don’t have a knee extension machine at home, so you could try out a wall sit instead!

🔑It may be useful during the season of competition to decrease pain and allow the athlete to compete, if needed.

Stigmata of Chronic Obstructive Pulmonary Disease samer kareem 2,746 بازدیدها • پیش 3 سال ها

Chronic obstructive pulmonary disease (COPD) is defined as progressive, chronic airflow obstruction due to chronic bronchitis, emphysema, or both. The majority of patients have components of both, although one of these entities will frequently dominate the clinical picture. Emphysema�airspace enlargement distal to the terminal bronchioles due to destruction of alveolar septa. Chronic bronchitis�chronic airway inflammation and bronchospasm. Clinically defined as productive cough lasting for at least 3 mo over 2 consecutive years. Although COPD is irreversible, patients with acute exacerbations do have reversible bronchospastic and inflammatory components.
