Chronic obstructive pulmonary disease (COPD) is defined as progressive, chronic airflow obstruction due to chronic bronchitis, emphysema, or both. The majority of patients have components of both, although one of these entities will frequently dominate the clinical picture. Emphysema�airspace enlargement distal to the terminal bronchioles due to destruction of alveolar septa. Chronic bronchitis�chronic airway inflammation and bronchospasm. Clinically defined as productive cough lasting for at least 3 mo over 2 consecutive years. Although COPD is irreversible, patients with acute exacerbations do have reversible bronchospastic and inflammatory components.
A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back, or arms, as well as fatigue, lightheadedness, abnormal heartbeat, and anxiety. Women are more likely to have atypical symptoms than men. Treatment ranges from lifestyle changes and cardiac rehabilitation to medications, stents, and bypass surgery.
Chronic kidney disease includes conditions that damage your kidneys and decrease their ability to keep you healthy by doing the jobs listed. If kidney disease gets worse, wastes can build to high levels in your blood and make you feel sick. You may develop complications like high blood pressure, anemia (low blood count), weak bones, poor nutritional health and nerve damage. Also, kidney disease increases your risk of having heart and blood vessel disease. These problems may happen slowly over a long period of time. Chronic kidney disease may be caused by diabetes, high blood pressure and other disorders. Early detection and treatment can often keep chronic kidney disease from getting worse. When kidney disease progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life.
Women are routinely invited to have cervical screening tests (also called smear tests). The tests are done to prevent cervical cancer, not to diagnose cancer. During each test some cells are removed from the neck of the womb (cervix), with a plastic brush. The cells are examined under a microscope to look for early changes that, if ignored and not treated, could develop into cancer of the cervix. You are very unlikely to develop cervical cancer if you have regular cervical screening tests at the times advised by your doctor. If the test shows any abnormality, you will have treatment to stop you ever getting cancer of the cervix. So, an abnormal test does not mean you have cancer. It means you should have some treatment to stop you getting cancer.
No condom prevents pregnancy or sexually transmitted diseases (STDs) 100% of the time. But if you and your partner are having sex, nothing protects against STDs better than a properly used condom. For those having sex, condoms must always be used to protect against STDs even when using another method of birth control.
A flail chest occurs when a segment of the thoracic cage is separated from the rest of the chest wall. This is usually defined as at least two fractures per rib (producing a free segment), in at least two ribs. A segment of the chest wall that is flail is unable to contribute to lung expansion. Large flail segments will involve a much greater proportion of the chest wall and may extend bilaterally or involve the sternum. In these cases the disruption of normal pulmonary mechanics may be large enough to require mechanical ventilation.
Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain. You can develop vascular dementia after a stroke blocks an artery in your brain, but strokes don't always cause vascular dementia. Whether a stroke affects your thinking and reasoning depends on your stroke's severity and location. Vascular dementia also can result from other conditions that damage blood vessels and reduce circulation, depriving your brain of vital oxygen and nutrients
Endoscopy of Mammary Ducts with Micro-Endoscope called Mammary Ductoscopy. Indication:- Nipple Discharge. In this case Papilloma seen quite clearly. Biopsy can also be possible with Ductoscopy. Mammary Ductoscopy is very useful for diagnosis of Breast Cancer in early stage.
Holoprosencephaly (HPE, once known as arhinencephaly) is a cephalic disorder in which the prosencephalon (the forebrain of the embryo) fails to develop into two hemispheres. Normally, the forebrain is formed and the face begins to develop in the fifth and sixth weeks of human pregnancy. The condition also occurs in other species, as with Cy, the Cyclops kitten.
Indwelling urinary catheters are commonly used in hospitals and can lead to preventable catheter-associated UTI. How can rates of catheter-associated UTI be reduced in hospitals? New research findings are summarized in a new NEJM Quick Take. Learn more at http://nej.md/1WoeHdF SHOW MORE
The most common position of the uterus is anteverted (cervix angles forward) and anteflexed (body is flexed forward). The position of the uterus in the adult is liable to considerable variation, depending chiefly on the condition of the bladder and rectum. Adnexa: In gynecology, the appendages of the uterus, namely the ovaries, the Fallopian tubes, and the ligaments that hold the uterus in place.
Beating heart or "off pump" coronary artery surgery is the latest revolution in the management coronary disease. It is being embraced world-wide by increasing numbers of surgeons. Many of the advantages are subtle but reduced mortality, stroke, and bleeding as well as earlier discharge are well-established benefits. A cardiac stabiliser is mandatory for this surgery, most are single use only and very expensive, this one is multiple use and is saving many healthcare dollars
