Artrit rheumatoid? how exercise control it...

Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease of unknown cause. The hallmark feature of this condition is persistent symmetric polyarthritis (synovitis) that affects the hands and feet, though any joint lined by a synovial membrane may be involved. Extra-articular involvement of organs such as the skin, heart, lungs, and eyes can be significant. (See Clinical Presentation.)

Osteoporosis

Pathophysiology

It is increasingly being recognized that multiple pathogenetic mechanisms interact in the development of the osteoporotic state. Understanding the pathogenesis of osteoporosis starts with knowing how bone formation and remodeling occur.

Smoking Kills: 6 Major Organs Damaged By Cigarette Smoke

As the smoke hits your lungs, the chemicals it contains begin to work their way throughout the rest of your body. włodi, CC 

Mucous isn’t even the half of it. Neither is losing all sense of stamina, or coming home to a stale-smelling house with yellowed walls and furniture. No, the biggest consequences of smoking are, by and large, one you will never see. These, however, tend to be the deadliest.

Hepatitis B all we have to know

Key facts

• Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease.
• The virus is transmitted through contact with the blood or other body fluids of an infected person.
• An estimated 240 million people are chronically infected with hepatitis B (defined as hepatitis B surface antigen positive for at least 6 months).
• Approximately 780 000 persons die each year from hepatitis B infection -- 650 000 from cirrhosis and liver cancer due to chronic hepatitis B infection and another 130 000 from acute hepatitis B.1
• Hepatitis B is an important occupational hazard for health workers.
• However, it can be prevented by currently available safe and effective vaccine.

Acute sinusitis

Epidemiology

Sinusitis affects 1 out of every 7 adults in the United States, with more than 30 million individuals diagnosed each year. Sinusitis is more common from early fall to early spring. Rhinosinusitis affects an estimated 35 million people per year in the United States and accounts for close to 16 million office visits per year.

Tetralogy of fallot

Tetralogy of Fallot, which is one of the most common congenital heart disorders, comprises right ventricular (RV) outflow tract obstruction (RVOTO) (infundibular stenosis), ventricular septal defect (VSD), aorta dextroposition, and RV hypertrophy (see the image below). The mortality rate in untreated patients reaches 50% by age 6 years, but in the present era of cardiac surgery, children with simple forms of tetralogy of Fallot enjoy good long-term survival with an excellent quality of life.

Aortic dissections classification

Classification of aortic dissection

Percentage	60%	10–15%	25–30%
Type	DeBakey I	DeBakey II	DeBakey III
	Stanford A (Proximal)		Stanford B (Distal)

Several different classification systems have been used to describe aortic dissections. The systems commonly in use are based on either the anatomy of the dissection or the duration of onset of symptoms prior to presentation. The Stanford system is used more commonly now, as it is more attuned to the management of the patient.

Coronary Artery Disease - Coronary Heart Disease

Coronary heart disease is a common term for the buildup of plaque in the heart’s arteries that could lead to heart attack. But what about coronary artery disease? Is there a difference?  

The short answer is often no — health professionals frequently use the terms interchangeably.

However, coronary heart disease , or CHD, is actually a result of coronary artery disease, or CAD, said Edward Fisher, M.D., Ph.D., an American Heart Association volunteer who is the Leon H. Charney Professor of Cardiovascular Disease and director of the Center for the Prevention of Cardiovascular Disease at the NYU School of Medicine.

With coronary artery disease, plaque first grows in the coronary arteries until the blood flow to the heart’s muscle is limited. View an illustration of coronary arteries. This is also called ischemia. It may be chronic, caused by narrowing of the coronary artery and limitation of the blood supply to part of the muscle. Or it can be acute, resulting from a sudden plaque that ruptures.

Types of Diabetes Mellitus
