To understand congenital heart defects, it's helpful to know how a healthy heart works. Your child's heart is a muscle about the size of his or her fist. The heart works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart. Arteries are blood vessels that carry blood away from the heart to the body.

The hip is a "ball-and-socket" joint. In a normal hip, the ball at the upper end of the thighbone (femur) fits firmly into the socket, which is part of the large pelvis bone. In babies and children with developmental dysplasia (dislocation) of the hip (DDH), the hip joint has not formed normally.

What Are Sleep Disorders? Circadian Rhythm Disorders Typically, people sleep at night -- thanks not only to the conventions of the 9-to-5 workday, but also to the close interaction between our natural sleep and alertness rhythms, which are driven by an internal "clock." This clock is a small part of the brain called the suprachiasmatic nucleus of the hypothalamus. It sits just above the nerves leaving the back of our eyes. Light and exercise "reset" the clock and can move it forward or backward. Abnormalities related to this clock are called circadian rhythm disorders ("circa" means "about," and "dies" means "day"). Circadian rhythm disorders include jet lag, adjustments to shift work, delayed sleep phase syndrome (you fall asleep and wake up too late), and advanced sleep phase syndrome (you fall asleep and wake up too early).

Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.

Initial treatment of a deviated septum may be directed at managing the symptoms of the tissues lining the nose, which may then contribute to symptoms of nasal obstruction and drainage. Your doctor may prescribe: Decongestants. Decongestants are medications that reduce nasal tissue swelling, helping to keep the airways on both sides of your nose open. Decongestants are available as a pill or as a nasal spray. Use nasal sprays with caution, however. Frequent and continued use can create dependency and cause symptoms to be worse (rebound) after you stop using them. Decongestants have a stimulant effect and may cause you to be jittery as well as elevate your blood pressure and heart rate. Antihistamines. Antihistamines are medications that help prevent allergy symptoms, including obstruction and runny nose. They can also sometimes help nonallergic conditions such as those occurring with a cold. Some antihistamines cause drowsiness and can affect your ability to perform tasks that require physical coordination, such as driving. Nasal steroid sprays. Prescription nasal corticosteroid sprays can reduce inflammation in your nasal passage and help with obstruction or drainage. It usually takes from one to three weeks for steroid sprays to reach their maximal effect, so it is important to follow your doctor's directions in using them. Medications only treat the swollen mucus membranes and won't correct a deviated septum.

Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, your heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels open up to improve blood flow. Examples of beta blockers Some beta blockers mainly affect your heart, while others affect both your heart and your blood vessels. Which one is best for you depends on your health and the condition being treated. Examples of oral beta blockers include: Acebutolol (Sectral) Atenolol (Tenormin) Bisoprolol (Zebeta) Metoprolol (Lopressor, Toprol-XL) Nadolol (Corgard) Nebivolol (Bystolic) Propranolol (Inderal LA, InnoPran XL)
