Constrictive pericarditis is the result of scarring and consequent loss of the normal elasticity of the pericardial sac. This leads to impairment of ventricular filling in mid and late diastole. As a result, the majority of ventricular filling occurs rapidly in early diastole and the ventricular volume does not increase after the end of the early filling period. Restrictive cardiomyopathy is characterized by a nondilated rigid ventricle, resulting in severe diastolic dysfunction and restrictive filling that produces hemodynamic changes similar to those in constrictive pericarditis. Constrictive pericarditis and restrictive cardiomyopathy both lead to diastolic heart failure with normal (or near normal) systolic function, and characteristically abnormal ventricular filling that results in similar clinical and hemodynamic features. However, because of their markedly different treatments, differentiating between the two conditions is critical. In some patients, the correct diagnosis may be readily suggested from the history or routine diagnostic testing. In others, however, this differentiation cannot be diagnosed before biopsy or even surgical exploration.

Every 10 minutes, someone is added to the national transplant waiting list, and every day, 22 people on average die waiting for a match, according to the United Network for Organ Sharing. But, thanks to innovations in bioengineering, all of that could change. Conceived nearly 60 years ago, the total artificial heart (TAH) has helped sustain the sickest biventricular failure patients waiting for a transplant. While the design of the primary TAH used today has mostly remained stagnant since the โ€™80s, when it was first implanted in a patient, new models and clinical trials may lead to a better device and, one day, a permanent solution. โ€œWe are still many years away from that,โ€ Dr. Nader Moazami, director of the Cardiac Transplantation and Ventricular Assist Device Therapy Program at the Cleveland Clinic, told FoxNews.com of a permanent artificial heart. โ€œAlthough tremendous strides have been made, biocompatibility will always remain a challenge.โ€

This video is really sad. You can literally watch this man dying. He was shot in the chest and rushed to the emergency room. His heart has stopped beating or has arrested. As a last resort, surgeons did an extreme procedure called an open thoracotomy which is that crazy tool you see there that basically splits the ribs open and allows easy open access to the heart. They did this so they could give him a cardiac massage. A cardiac massage is when surgeons are manually trying to pump the heart after it has stopped working on its own (cardiac arrest). Unfortunately he lost so much blood from his gun shot wound and he was pronounced dead. There are cases of patients surviving after having this kind of invasive resuscitation but it is rare.

Recovery can take 4 to 6 months, depending on the size of the tear and other factors. You may have to wear a sling for 4 to 6 weeks after surgery. Pain is usually managed with medicines. Physical therapy can help you regain the motion and strength of your shoulder.

In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself.

Colon polyp facts Colon polyps are growths on the inner lining of the colon and are very common. Colon polyps are important because they may be, or may become malignant (cancerous). They also are important because based on their size, number, and microscopic anatomy (histology); they can predict which patients are more likely to develop more polyps and colon cancer. Changes in the genetic material of cells lining the colon are the cause of polyps. There are different types of colon polyps with differing tendencies to become malignant and abilities to predict the development of more polyps and cancer. It is important to recognize families with members who have familial genetic conditions causing polyps because some of these conditions are associated with a very high incidence of colon cancer, and the cancer can be prevented or discovered early.

Bartter syndrome, originally described by Bartter and colleagues in 1962, [1] represents a set of closely related, autosomal recessive renal tubular disorders characterized by hypokalemia, hypochloremia, metabolic alkalosis, and hyperreninemia with normal blood pressure. The underlying renal abnormality results in excessive urinary losses of sodium, chloride, and potassium.

HIV gradually destroys the immune system by attacking and killing a type of white blood cell called a CD4 cell. CD4 cells play a major role in protecting the body from infection. HIV uses the machinery of the CD4 cells to multiply (make copies of itself) and spread throughout the body. This process, which is carried out in seven steps or stages, is called the HIV life cycle. HIV medicines protect the immune system by blocking HIV at different stages of the HIV life cycle. Antiretroviral therapy or ART is the use of HIV medicines to treat HIV infection. People on ART take a combination of HIV medicines from at least two different HIV drug classes every day. Because each class of drugs is designed to target a specific step in the HIV life cycle, ART is very effective at preventing HIV from multiplying. ART also reduces the risk of HIV drug resistance. ART canโ€™t cure HIV, but HIV medicines help people with HIV live longer, healthier lives. ART also reduces the risk of HIV transmission (the spread of HIV to others).

A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
