Most folks remember puberty – and not always in a good way. It can be an awkward stage of budding breasts, unwanted hair, acne and unexpected body odor. Puberty, when a child undergoes physical changes and becomes sexually mature, typically begins around age 8 in girls and age 9 in boys. But imagine, say, a 6- or 7-year-old undergoing such changes? Studies are showing that the onset of puberty for both boys and girls is occurring earlier and earlier, a phenomenon defined as precocious puberty. A study published in Pediatrics in 2010 found that among a population of 1,200 American girls, about 23 percent of African-Americans,15 percent of Latinas and 10 percent of Caucasian girls had begun puberty (marked by breast development) at age 7. In 2012, another study published in Pediatrics found that puberty in American boys – measured by testicular enlargement and pubic hair growth – was beginning six months to two years earlier than what research in previous decades had documented, particularly among African-American children.
Aspirin is a salicylate (sa-LIS-il-ate). It works by reducing substances in the body that cause pain, fever, and inflammation. Aspirin is used to treat pain, and reduce fever or inflammation. It is sometimes used to treat or prevent heart attacks, strokes, and chest pain (angina).
The lymphatic system is a network of specialized vessels (lymph vessels) throughout the body whose purpose is to collect excess lymph fluid with proteins, lipids, and waste products from the tissues. This fluid is then carried to the lymph nodes, which filter waste products and contain infection-fighting cells called lymphocytes. The excess fluid in the lymph vessels is eventually returned to the bloodstream. When the lymph vessels are blocked or unable to carry lymph fluid away from the tissues, localized swelling (lymphedema) is the result.

Transvenous cardiac pace maker, also called endocardial pacing, is a potentially life saving intervention used primarily to correct profound bradycardia. It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy.
Prompted by the hormone prolactin, the alveoli take proteins, sugars, and fat from your blood supply and make breast milk. A network of cells surrounding the alveoli squeeze the glands and push the milk out into the ductules, which lead to a bigger duct.
The Epley maneuver is a series of movements, normally carried out on a person by a doctor, to relieve the symptoms of BPPV. Research has found it to be an easy, safe, and effective treatment for the condition in both the long- and short-term. The Epley maneuver is sometimes called the particle repositioning maneuver or the canalith repositioning maneuver. These names are used because the maneuver involves a series of movements that help to reposition crystals in a person's ear that may cause feelings of dizziness. Repositioning the crystals helps to relieve the person's dizziness and nausea.
protecting the body from damage caused by hyperglycemia cannot be overstated. In the United States, 57.9% of diabetic patients have one or more diabetes complications, and 14.3% have three or more.1 Strict glycemic control is the primary method of reducing the development and progression of microvascular complications, such as retinopathy, nephropathy, and neuropathy. Aggressive treatment of dyslipidemia and hypertension decreases macrovascular complications.2-4 Glycemic Control There are two primary techniques available for physicians to assess the quality of a patient’s glycemic control: self-monitoring of blood glucose (SMBG) and interval measurement of hemoglobin A1c (HbA1c).
The biceps muscle is located in the front of your upper arm. It is attached to the bones of the shoulder and elbow by tendons — strong cords of fibrous tissue that attach muscles to bones. Tears of the biceps tendon at the elbow are uncommon. They are most often caused by a sudden injury and tend to result in greater arm weakness than injuries to the biceps tendon at the shoulder. Once torn, the biceps tendon at the elbow will not grow back to the bone and heal. Other arm muscles make it possible to bend the elbow fairly well without the biceps tendon. However, they cannot fulfill all the functions of the elbow, especially the motion of rotating the forearm from palm down to palm up. This motion is called supination. To return arm strength to near normal levels, surgery to repair the torn tendon is usually recommended. However, nonsurgical treatment is a reasonable option for patients who may not require full arm function.
Superior vena cava syndrome (SVCS) is obstruction of blood flow through the superior vena cava (SVC). It is a medical emergency and most often manifests in patients with a malignant disease process within the thorax. A patient with SVCS requires immediate diagnostic evaluation and therapy.
Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.
Homocystinuria is an inherited disorder that affects the metabolism of the amino acid methionine. Amino acids are the building blocks of life. Causes Homocystinuria is inherited in families as an autosomal recessive trait. This means that the child must inherit a non-working copy of the gene from each parent to be seriously affected. Homocystinuria has several features in common with Marfan syndrome, including joint and eye changes. Symptoms Newborn infants appear healthy. Early symptoms, if present, are not obvious. Symptoms may occur as mildly delayed development or failure to thrive. Increasing visual problems may lead to diagnosis of this condition. Other symptoms include: Chest deformities (pectus carinatum, pectus excavatum) Flush across the cheeks High arches of the feet Intellectual disability Knock knees Long limbs Mental disorders Nearsightedness Spidery fingers (arachnodactyly) Tall, thin build
