Detecting Malingering, Misleading Patients samer kareem 1,839 Views • 3 years ago

Factitious disorder is the term used to describe a pattern of behavior centered on the exaggeration or outright falsifications of one’s own health problems or health problems of others. Some people with this disorder fake or exaggerate physical problems; others fake or exaggerate psychological problems or a combination of physical and psychological problems. Factitious disorder differs from a pattern of falsified or exaggerated behavior called malingering. While malingerers make their claims out of a motivation for personal gain, people with factitious disorder have no such motivation.

Blunt cardiac rupture
Blunt cardiac rupture samer kareem 1,838 Views • 3 years ago

Blunt injury to the heart ranges from contusion to disruption. This report comprises 14 patients seen during a 6-year period with cardiac rupture secondary to blunt trauma. Eight patients were injured in automobile accidents, two patients were injured in auto-pedestrian accidents, two were kicked in the chest by ungulates, and two sustained falls. Cardiac tamponade was suspected in ten patients. Five patients presented with prehospital cardiac arrest or arrested shortly after arrival. All underwent emergency department thoracotomy without survival. Two patients expired in the operating room during attempted cardiac repair; both had significant extracardiac injury. Seven patients survived, three had right atrial injuries, three had right ventricular injuries, and one had a left atrial injury. Cardiopulmonary bypass was not required for repair of the surviving patients. There were no significant complications from the cardiac repair.

Vascular dementia
Vascular dementia samer kareem 1,832 Views • 3 years ago

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

Why Do We Sneeze?
Why Do We Sneeze? samer kareem 1,832 Views • 3 years ago

The long-standing answer has been that sneezing is a reflex. When irritants — such as germs, dust, pollen, animal dander, or pollutants, just to name just a few — infiltrate the nose lining, the brain sends out a signal to get rid of it. That triggers a deep breath, which gets held in the lungs.

Beta Blockers
Beta Blockers samer kareem 1,831 Views • 3 years ago

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)

Cystic Fibrosis Pulmonary Disease
Cystic Fibrosis Pulmonary Disease samer kareem 1,825 Views • 3 years ago

Cystic fibrosis (CF) is a multisystem disease affecting the digestive system, sweat glands, upper and lower respiratory tracts, and the reproductive tract, but progressive lung disease continues to be the major cause of morbidity and mortality [1]. CF is characterized by abnormal transport of chloride and sodium across the respiratory epithelium, resulting in thickened, viscous airway secretions [2]. Over a highly variable time course ranging from months to decades after birth, individuals eventually develop chronic infection of the respiratory tract with a characteristic array of bacterial flora [3], leading to progressive respiratory insufficiency and eventual respiratory failure. The rate of progression varies widely, depending in part on genotype (including gene modifiers) as well as environmental factors. Registry data from CF Centers in the United States, Canada, and Europe indicate a median survival of about 41 years [4]. Females with CF appear to have higher morbidity and mortality than males [5]. This "gender gap" is modest but consistent across many populations and is hypothesized to be due to the pro-inflammatory effects of estrogens.

Aortoiliac Occlusive Disease
Aortoiliac Occlusive Disease samer kareem 1,825 Views • 3 years ago

Aortoiliac occlusive disease (AIOD) occurs commonly in patients with PAD. Significant lesions in the aortoiliac arterial segment are exposed easily by palpation of the femoral pulses. Any diminution of the palpable femoral pulse indicates that a more proximal obstruction exists. Obstructive lesions may be present in the infrarenal aorta, common iliac, internal iliac (hypogastric), external iliac, or combinations of any or all of these vessels. Occasionally, degenerated nonstenotic atheromatous disease exists in these vessels and may manifest by atheroembolism to the foot, the "blue toe" or "trash foot" syndrome. Generally, patients with aortoiliac PAD have a poorer general prognosis than those with more distal PAD.
