The "great arteries" in this anomaly refer to the aorta and the pulmonary artery, the two major arteries carrying blood away from the heart. In cases of transposition of the great arteries, these vessels arise from the wrong ventricle. They are "transposed" from their normal position so that the aorta arises from the right ventricle and the pulmonary artery from the left ventricle. Other heart defects may occur along with transposition of the great arteries. About 25 percent of children with transposition will also have a ventricular septal defect (VSD) . In nearly a third, the branching pattern of the coronary arteries as they leave the transposed aorta is unusual. Infants may also have narrowing below the pulmonary valve that blocks blood flow from the left ventricle to the lungs.

The etiology of BOO is diverse and definitely gender specific. Often anatomic causes induce functional abnormality that remains somewhat unique for each individual, regardless of sex. A full appreciation of the possible etiologies of obstruction is necessary in order to identify overt and more subtle scenarios. In women, iatrogenic causes of obstruction are the most common. Other entities account for far fewer of the cases. The obstruction evaluation in women is somewhat more diverse in terms of modalities used, with no single grouping of techniques that are generally apropos. Individualized evaluation remains a tenet of analysis, and urodynamic criteria used to diagnose BOO in women continue to evolve.

Symptoms range from nonspecific and constitutional to sudden cardiac death. [18] In about 20% of cases, myxomas may be asymptomatic and discovered as an incidental finding. Signs and symptoms of mitral stenosis, endocarditis, mitral regurgitation, and collagen vascular disease can simulate those of atrial myxoma. A high index of suspicion aids in diagnosis. Symptoms of left-sided heart failure include the following: Dyspnea on exertion (75%) that may progress to orthopnea, paroxysmal nocturnal dyspnea, and pulmonary edema is observed. [19, 20] Symptoms are caused by obstruction at the mitral valve orifice. Valve damage may result in mitral regurgitation.

Beckwith-Wiedemann Syndrome (BWS) is a congenital overgrowth syndrome, which can affect all systems of the body. It was first recognised in 1963-64 by Dr J. Bruce Beckwith, a paediatric pathologist in America and, independently, by Dr H.E. Wiedemann, a German geneticist.

Everyone feels sad or low sometimes, but these feelings usually pass with a little time. Depressionโ€”also called โ€œclinical depressionโ€ or a โ€œdepressive disorderโ€โ€”is a mood disorder that causes distressing symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. To be diagnosed with depression, symptoms must be present most of the day, nearly every day for at least 2 weeks.

The cause for TS is unknown. Early research suggested that TS is an inherited condition (often, the person's near or distant relatives have had some form of transient or chronic tic disorder or associated symptoms). Recent studies point to a combination of environmental and genetic factors as a cause of the disorder. The specific genes involved in the development of TS are still being investigated. Studies suggest that TS has a neurological basis and results from an abnormality which affects the brain's metabolism of certain neurotransmitters (chemicals in the brain that regulate behavior.) Current research being funded by the Tourette Syndrome Association (TSA) will help provide more information about the causes and genetic factors of TS.

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

A pneumothorax (noo-moe-THOR-aks) is a collapsed lung. A pneumothorax occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. In most cases, only a portion of the lung collapses.

Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. Risk for chronic infection is related to age at infection: approximately 90% of infected infants become chronically infected, compared with 2%โ€“6% of adults. Chronic Hepatitis B can lead to serious health issues, like cirrhosis or liver cancer. The best way to prevent Hepatitis B is by getting vaccinated.

Scientists have developed a gene editing technique which targets HIV-1 DNA. Through the technique, scientists successfully edited the virus out the genome in human cells; their study also showed the technique can prevent viral replication in cleared cells. Using CRISPR/Cas9 gene editing, the team tested patient cells grown in a lab which were no longer susceptible to HIV infection.

Your temporomandibular joint is a hinge that connects your jaw to the temporal bones of your skull, which are in front of each ear. It lets you move your jaw up and down and side to side, so you can talk, chew, and yawn. Problems with your jaw and the muscles in your face that control it are known as temporomandibular disorders (TMD). But you may hear it wrongly called TMJ, after the joint.
