The thyroid gland lies in the midline of the anterior neck, just caudal to the thyroid cartilage. To inspect the thyroid gland, the examiner stands in front of the patient. The examiner asks the seated patient to dorsiflex (extend) the neck and swallow a sip of water. Minor enlargement of the gland may only become apparent on inspection in this position. Palpation of the thyroid gland is typically performed with the examiner standing behind the patient. Both lobes and the isthmus of the thyroid gland should be palpated for any nodules or diffuse enlargement. Mobility of the thyroid gland with swallowing should be assessed with palpation. Nodules arising from the thyroid gland typically move with swallowing. A hard, fixed thyroid gland could indicate malignancy. If a central nodule is identified, the patient is asked to protrude the tongue. Upward movement of the central nodule on protrusion of the tongue indicates a thyroglossal cyst. Auscultation is performed at the superior poles of bilateral lobes as this is where the superior thyroid artery is most superficial and bifurcates into its terminal branches. A bilateral bruit over the superior poles suggests Graves disease. Examination of the thyroid gland is completed by palpating the regional cervical lymph nodes for any enlargement.

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).
Although your body may harbor the bacteria that cause tuberculosis, your immune system usually can prevent you from becoming sick. For this reason, doctors make a distinction between: Latent TB. In this condition, you have a TB infection, but the bacteria remain in your body in an inactive state and cause no symptoms. Latent TB, also called inactive TB or TB infection, isn't contagious. It can turn into active TB, so treatment is important for the person with latent TB and to help control the spread of TB. An estimated 2 billion people have latent TB. Active TB. This condition makes you sick and can spread to others. It can occur in the first few weeks after infection with the TB bacteria, or it might occur years later. Signs and symptoms of active TB include: Coughing that lasts three or more weeks Coughing up blood Chest pain, or pain with breathing or coughing Unintentional weight loss Fatigue Fever Night sweats
Kegel exercises strengthen the pelvic floor muscles, which support the uterus, bladder, small intestine and rectum. You can do Kegel exercises, also known as pelvic floor muscle training, just about anytime. Start by understanding what Kegel exercises can do for you — then follow step-by-step instructions for contracting and relaxing your pelvic floor muscles.
Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus.
Hypertrophic cardiomyopathy (HCM) is very common and can affect people of any age. It affects men and women equally. It is a common cause of sudden cardiac arrest in young people, including young athletes. Hypertrophic cardiomyopathy occurs if heart muscle cells enlarge and cause the walls of the ventricles (usually the left ventricle) to thicken. The ventricle size often remains normal, but the thickening may block blood flow out of the ventricle. If this happens, the condition is called obstructive hypertrophic cardiomyopathy. Sometimes the septum, the wall that divides the left and right sides of the heart, thickens and bulges into the left ventricle. This can block blood flow out of the left ventricle. Then the ventricle must work hard to pump blood. Symptoms can include chest pain, dizziness, shortness of breath, or fainting. Hypertrophic cardiomyopathy also can affect the heart's mitral valve, causing blood to leak backward through the valve. Sometimes, the thickened heart muscle doesn't block blood flow out of the left ventricle. This is referred to as non-obstructive hypertrophic cardiomyopathy. The entire ventricle may thicken, or the thickening may happen only at the bottom of the heart. The right ventricle also may be affected. In both obstructive and non-obstructive HCM, the thickened muscle makes the inside of the left ventricle smaller, so it holds less blood. The walls of the ventricle may stiffen, and as a result, the ventricle is less able to relax and fill with blood.
Ventricular fibrillation is a heart rhythm problem that occurs when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly, instead of pumping blood. Sometimes triggered by a heart attack, ventricular fibrillation causes your blood pressure to plummet, cutting off blood supply to your vital organs. Ventricular fibrillation, an emergency that requires immediate medical attention, causes the person to collapse within seconds. It's the most frequent cause of sudden cardiac death. Emergency treatment includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called a defibrillator. Treatments for those at risk of ventricular fibrillation include medications and implantable devices that can restore a normal heart rhythm.
