Megacolon
Megacolon samer kareem 3,024 Views • 2 years ago

Megacolon, as well as megarectum, is a descriptive term. It denotes dilatation of the colon that is not caused by mechanical obstruction.[1, 2] Although the definition of megacolon has varied in the literature, most researchers use the measurement of greater than 12 cm for the cecum as the standard. Because the diameter of the large intestine varies, the following definitions would also be considered: greater than 6.5 cm in the rectosigmoid region and greater than 8 cm for the ascending colon. Megacolon can be divided into the following 3 categories: Acute megacolon ( pseudo-obstruction) Chronic megacolon, which includes congenital, acquired, and idiopathic causes Toxic megacolon

Surfactant Dysfunction
Surfactant Dysfunction samer kareem 1,493 Views • 2 years ago

Genetic surfactant dysfunction disorders are caused by mutations in genes encoding proteins critical for the production and function of pulmonary surfactant. These rare disorders may produce familial or sporadic lung disease, with clinical presentations ranging from neonatal respiratory failure to childhood- or adult-onset interstitial lung disease. An overview of these disorders is presented in the table.. Interstitial lung diseases in children until recently were categorized by their histologic appearance in a manner similar to that used for adult forms of interstitial lung disease (ILD). In children, the lung histopathology findings associated with desquamative interstitial pneumonitis (DIP) are now known to often result from genetic mechanisms that disrupt normal surfactant production and metabolism. By contrast, DIP in adults is considered to represent a distinct type of ILD, which is strongly associated with cigarette smoking and carries a relatively favorable prognosis [1]. These genetic disorders also result in histopathologic patterns other than DIP, including findings of pulmonary alveolar proteinosis and chronic pneumonitis of infancy. An understanding of the pathogenesis of these disorders permits a mechanistic classification as genetic surfactant dysfunction disorders instead of their previous classification based upon histologic appearance.

Wrist Arthrocentesis
Wrist Arthrocentesis samer kareem 2,949 Views • 2 years ago

A needle is inserted into a joint for two main indications: aspiration of fluid (arthrocentesis) for diagnosis or for relief of pressure, or injection of medications. In practical terms, most injections into joints consist of a glucocorticoid, a local anesthetic, or a combination of the two. Occasionally saline is injected into the joint to diagnose a joint injury. This topic will review the basic technique of inserting a needle into a joint and the main indications for intraarticular steroid injections. The same techniques apply for injection of the less commonly used hyaluronate viscosupplementation agents into knees, hips, and perhaps shoulders.

INDICATIONS The Absorb GT1 Bioresorbable Vascular Scaffold (BVS) is a temporary scaffold that will fully resorb over time and is indicated for improving coronary luminal diameter in patients with ischemic heart disease due to de novo native coronary artery lesions (length ≤ 24 mm) with a reference vessel diameter of ≥ 2.5 mm and ≤ 3.75 mm WHAT ARE THE POTENTIAL RISKS AND COMPLICATIONS? Treatment options for CAD have become increasingly common but, as with any invasive procedure, there are potential risk factors and complications. Serious complications do not occur often, and research is ongoing to make these procedures even safer and more effective. The risk of complications from percutaneous treatment methods may be higher for individuals: 75 years of age and older Who are women Who have kidney disease or diabetes Who have serious heart disease Who have had prior cardiac interventions

Autoimmune Hepatitis
Autoimmune Hepatitis samer kareem 15,572 Views • 2 years ago

Autoimmune hepatitis is liver inflammation that occurs when your body's immune system turns against liver cells. The exact cause of autoimmune hepatitis is unclear, but genetic and environmental factors appear to interact over time in triggering the disease. Untreated autoimmune hepatitis can lead to scarring of the liver (cirrhosis) and eventually to liver failure. When diagnosed and treated early, however, autoimmune hepatitis often can be controlled with drugs that suppress the immune system. A liver transplant may be an option when autoimmune hepatitis doesn't respond to drug treatments or when liver disease is advanced.

Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.

Genetic Disorders And Diseases
Genetic Disorders And Diseases samer kareem 4,460 Views • 2 years ago

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

Acute Respiratory Distress Syndrome
Acute Respiratory Distress Syndrome samer kareem 2,468 Views • 2 years ago

Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. More fluid in your lungs means less oxygen can reach your bloodstream. This deprives your organs of the oxygen they need to function. ARDS typically occurs in people who are already critically ill or who have significant injuries. Severe shortness of breath — the main symptom of ARDS — usually develops within a few hours to a few days after the original disease or trauma. Many people who develop ARDS don't survive. The risk of death increases with age and severity of illness. Of the people who do survive ARDS, some recover completely while others experience lasting damage to their lungs.

liver abcess
liver abcess samer kareem 1,679 Views • 2 years ago

Bacterial abscess of the liver is relatively rare; however, it has been described since the time of Hippocrates (400 BCE), with the first published review by Bright appearing in 1936. In 1938, Ochsner's classic review heralded surgical drainage as the definitive therapy; however, despite the more aggressive approach to treatment, the mortality remained at 60-80%.[1] The development of new radiologic techniques, the improvement in microbiologic identification, and the advancement of drainage techniques, as well as improved supportive care, have reduced mortality to 5-30%; yet, the prevalence of liver abscess has remained relatively unchanged. Untreated, this infection remains uniformly fatal. The three major forms of liver abscess, classified by etiology, are as follows: Pyogenic abscess, which is most often polymicrobial, accounts for 80% of hepatic abscess cases in the United States Amebic abscess due to Entamoeba histolytica accounts for 10% of cases [2] Fungal abscess, most often due to Candida species, accounts for fewer than 10% of cases

Cerebral Palsy
Cerebral Palsy samer kareem 6,699 Views • 2 years ago

Cerebral palsy is a disorder of movement, muscle tone or posture that is caused by damage that occurs to the immature, developing brain, most often before birth. Signs and symptoms appear during infancy or preschool years. In general, cerebral palsy causes impaired movement associated with abnormal reflexes, floppiness or rigidity of the limbs and trunk, abnormal posture, involuntary movements, unsteady walking, or some combination of these. People with cerebral palsy may have problems swallowing and commonly have eye muscle imbalance, in which the eyes don't focus on the same object. People with cerebral palsy also may suffer reduced range of motion at various joints of their bodies due to muscle stiffness. Cerebral palsy's effect on functional abilities varies greatly. Some affected people can walk while others can't. Some people show normal or near-normal intellectual capacity, but others may have intellectual disabilities. Epilepsy, blindness or deafness also may be present.

URBN Dental  How do you brush your teeth properly
URBN Dental How do you brush your teeth properly Daniel Cook 1,246 Views • 2 years ago

URBN Dental is here not only to take care of your tooth decay and prevent gingivitis, but also to give you the best at home dental care instructions as well. Do you find brushing your teeth confusing, or are you unsure whether or not you are brushing correctly? The golden standard when it comes to brushing teeth is brushing twice a day for two minute sessions each. You can break down the mouth into four quadrants: upper right, upper left, lower left, and lower right. By doing this, it will be easier for you to brush for thirty seconds in each area and focus on the correct movement instead of location. It is very important to angle the toothbrush at a forty five degree angle to the tooth and gums while using circular motions to remove food debris and plaque. When it comes to your front teeth, using the brush in a vertical position and combining it with circular motions is effective. Using the dental techniques will ensure healthier teeth that are cavity free and less bleeding gums.
