Hemorrhage is any profuse internal or external bleeding from the blood vessels. The most obvious cause of hemorrhage is trauma or injury to a blood vessel. Hemorrhage can also be caused by aneurysms or weak spots in the artery wall that are often present at birth.

Hypertension‚ or high blood pressure‚ is often a

medical procedures are increasing considerably. Effective and of good quality imaging is important for further medical decision making and can reduce unnecessary procedures. Reports from some countries indicate that a significant portion of all abdominal surgical interventions (explorative laparotomy) may have been avoided if simple diagnostic imaging services such as ultrasound had been available. 2) Compare and Contrast the following: X-Ray‚ Digital Subtraction Angiography‚ PET‚ Ultrasound

Relapsing polychondritis Syphilitic aortitis Systemic lupus erythematosus B The catheter data are characteristic of aortic incompetence: there is a wide pulse pressure in the aorta accompanied by a very high left ventricular end-diastolic pressure (LVEDP); a LVEDP greater than 20 mmHg is suggestive of irreversible LV dysfunction. All of the conditions listed are associated with aortic regurgitation. However‚ the clinical description best fits with Marfan’s syndrome. Marfan’s syndrome is a connective

"The substance of the lung is dilatable and extensible like the tinder made from a fungus. But it is spongy and if you press it‚ it yields to the force which compresses it‚ and if the force is removed‚ it increases again to its original size." - Leonardo da Vinci‚ late 15th century.23 The beginning of accurate knowledge concerning the physiology of breathing dates back to the 17th century. Before that time‚ the ideas in vogue about why and how we breathe were mystical and strange. Hippocrates “counted

We attributed this to the medications that were already taking effect on the day prior to conducting the physical examination. Administration of antibiotics and expectorants relieves the pulmonary congestion by reducing the bacterial load and purging the mucus that clogs the bronchi. The resolution of the disease in the patient
