Coronary artery vasospasm, or smooth muscle constriction of the coronary artery, is an important cause of chest pain syndromes that can lead to myocardial infarction (MI), ventricular arrhythmias, and sudden death. It also plays a key role in the development of atherosclerotic lesions.Nov 22, 2016

Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.

hemothorax is most often defined as rapid accumulation of ≥ 1000 mL of blood. Shock is common. Patients with large hemorrhage volume are often dyspneic and have decreased breath sounds and dullness to percussion (often difficult to appreciate during initial evaluation of patients with multiple injuries).

Dementia is the name for a group of symptoms that commonly include problems with memory, thinking, problem solving, language and perception. In a person with dementia, these symptoms are bad enough to affect daily life.

Dementia is not a specific disease. It's an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person's ability to perform everyday activities. Alzheimer's disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs after a stroke, is the second most common dementia type. But there are many other conditions that can cause symptoms of dementia, including some that are reversible, such as thyroid problems and vitamin deficiencies.

Atherosclerosis is a process in which blood, fats such as cholesterol, and other substances build up on your artery walls. Eventually, deposits called plaques may form. The deposits may narrow — or block — your arteries. These plaques can also rupture, causing a blood clot.

we use a single, tapered PDT dilator and kit . All the equipment and supplies listed must be present at the bed-side, because there is no time to go looking for supplies if an airway emergency occurs during the procedure. Two teams are used simultaneously. One team manages the endo-tracheal tube, and the other manages the placement of the tracheostomy tube

With so many antibiotics available, it isn't possible to list all of them here. But common antibiotics that are generally considered safe during pregnancy include penicillins (such as amoxicillin and ampicillin), cephalosporins (such as cephalexin), and erythromycin.

The procedure was performed under wrist block regional anesthesia with tourniquet control. A single Chinese finger trap was used on the thumb with 5 to 8 lb of ongitudinal traction. The arm was held down with wide tape around the tourniquet securing it to the hand table to serve as countertraction. A shoulder holder, rather than a traction tower, was used to facilitate fluoroscopic intervention more easily. The Trapeziometacarpal joint was detected by palpation. Joint distension was achieved by injecting 1 to 3 mL of normal saline (Fig. 1). It is important to distally direct the needle approximately 20 degrees to clear the dorsal flare of the metacarpal base and enter the joint capsule. This course should be reproduced upon entering with arthroscopic sleeve/ trocar assembly to minimize iatrogenic cartilage injury. Fluid distention is important to facilitate this. The incision for the 1-R (radial) portal, used for proper assessment of the dorsoradial ligament, posterior oblique ligament, and ulnar collateral ligament, was placed just volar to the abductor pollicis longus tendon. The incision for the 1-U (ulnar) portal, for better evaluation of the anterior oblique ligament and ulnar collateral ligament, was made just ulnar to the extensor pollicis brevis tendon. A short-barrel, 1.9-mm, 30- degree inclination arthroscope was used for complete visualization of the CMC joint surfaces, capsule, and ligaments, and then appropriate management was done, as dictated by the stage of the arthritis detected (Fig. 2A). A full-radius mechanical shaver with suction was used in all the cases, particularly for initial debridement and visualization. Most of the cases were augmented with radiofrequency ablation to perform a thorough synovectomy and radiofrequency was also used to perform chondroplasty in the cases with focal articular cartilage wear or fibrillation. Chondroplasty refers to thedebridement of the fibrillated cartilage to improve vascularity of the cartilage and enhance the growth of fibrocartilage. Ligamentous laxity and capsular attenu- ation were treated with thermal capsulorraphy using a radiofrequency shrinkage probe. We were careful to avoid thermal necrosis; hence, a striping technique was used to tighten the capsule of the lax joints. The striping technique refers to thermal shrinkage performed in longitudinal stripes on the lax capsule, so as to leave vascular zones between the stripes; hence, thermal necrosis is prevented. Arthroscopic stage I disease was characterized by synovitis without any cartilage wear, wherein a synovectomy coupled with thermal capsulor- raphy as described was performed.

COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it. At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include A cough that produces a lot of mucus Shortness of breath, especially with physical activity Wheezing Chest tightness Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.
