Cystic acne is a severe type of acne in which the pores in the skin become blocked, leading to infection and inflammation. The skin condition mainly affects the face, but also often affects the upper trunk and upper arms. Acne most often affects adolescents and young adults, with an estimated 80 percent of people between 11 and 30 years of age experiencing acne at some point. Cystic acne is the most severe form and affects far fewer people. In 2009, the Centers for Disease Control and Prevention (CDC) found that acne was the top reason people gave for visiting a dermatologist.
A meningioma is a tumor that arises from the meninges — the membranes that surround your brain and spinal cord. Most meningiomas are noncancerous (benign), though rarely a meningioma may be cancerous (malignant). Some meningiomas are classified as atypical, meaning they're neither benign nor malignant but, rather, something in between.
A liver abscess is a pus-filled mass inside the liver. Common causes are abdominal infections such as appendicitis or diverticulitis due to haematogenous spread through the portal vein. A pyogenic liver abscess (PLA) is a pocket of pus that forms in the liver in response to an infection or trauma. Pus is a fluid composed of white blood cells, dead cells, and bacteria that forms when your body fights off infection.Dec 11, 2015
When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.
Diabetic neuropathy is a type of nerve damage that can occur if you have diabetes. High blood sugar (glucose) can injure nerve fibers throughout your body, but diabetic neuropathy most often damages nerves in your legs and feet. Depending on the affected nerves, symptoms of diabetic neuropathy can range from pain and numbness in your extremities to problems with your digestive system, urinary tract, blood vessels and heart. For some people, these symptoms are mild; for others, diabetic neuropathy can be painful, disabling and even fatal. Diabetic neuropathy is a common serious complication of diabetes. Yet you can often prevent diabetic neuropathy or slow its progress with tight blood sugar control and a healthy lifestyle.
Superior capsule reconstruction (SCR) is a promising alternative treatment for irreparable posterosuperior rotator cuff tears (Figure 1). It utilizes a graft from the superior glenoid to the greater tuberosity to stabilize the humeral head. In a study by Mihata and colleagues of 23 patients who underwent SCR with a fascia lata autograft at a minimum of 2 years follow-up, the American Shoulder and Elbow Surgeons (ASES) score improved significantly from 23.5 preoperatively to 92.9. Postoperative MRI showed 83% of patients had intact reconstructions with no progression of muscle atrophy.
Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. It’s also called arteriosclerosis or hardening of the arteries. Arteries are the blood vessels that carry oxygen and nutrients from your heart to the rest of your body. As you get older, fat and cholesterol can collect in your arteries and form plaque. The buildup of plaque makes it difficult for blood to flow through your arteries. This buildup may occur in any artery in your body and can result in a shortage of blood and oxygen in various tissues of your body. Pieces of plaque can also break off, causing a blood clot. Atherosclerosis can lead to heart attack, stroke, or heart failure if left untreated.
