Normal and Abnormal Heart Sounds
Normal and Abnormal Heart Sounds samer kareem 4,526 Views • 2 years ago

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4.

Primary sclerosing  cholangitis
Primary sclerosing cholangitis samer kareem 2,472 Views • 2 years ago

Primary sclerosing (skluh-ROHS-ing) cholangitis (koh-lan-JIE-tis) is a disease of the bile ducts, which carry the digestive liquid bile from your liver to your small intestine. In primary sclerosing cholangitis, inflammation causes scars within the bile ducts. These scars make the ducts hard and narrow and gradually cause serious liver damage. In most people with primary sclerosing cholangitis, the disease progresses slowly and can lead to liver failure, repeated infections, and tumors of the bile duct or liver. Liver transplant is the only known cure for primary sclerosing cholangitis. The search for other treatments to slow or stop primary sclerosing cholangitis is ongoing, and scientists have turned up many promising leads. Until better treatments are proved safe and effective, though, care for primary sclerosing cholangitis focuses on monitoring liver function, managing symptoms and, when possible, doing procedures that temporarily open blocked bile ducts.

If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth. It also creates holes in the tooth called cavities. Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture.

Cytomegalovirus in solid organ transplant recipients
Cytomegalovirus in solid organ transplant recipients samer kareem 1,502 Views • 2 years ago

Cytomegalovirus (CMV) continues to have a tremendous impact in solid organ transplantation despite remarkable advances in its diagnosis, prevention and treatment. It can affect allograft function and increase patient morbidity and mortality through a number of direct and indirect effects. Patients may develop asymptomatic viremia, CMV syndrome or tissue-invasive disease. Late-onset CMV disease continues to be a major problem in high-risk patients after completion of antiviral prophylaxis. Emerging data suggests that immunologic monitoring may be useful in predicting the risk of late onset CMV disease. There is now increasing interest in the development of an effective vaccine for prevention. Novel antiviral drugs with unique mechanisms of action and lesser toxicity are being developed. Viral load quantification is now undergoing standardization, and this will permit the generation of clinically relevant viral thresholds for the management of patients. This article provides a brief overview of the contemporary epidemiology, clinical presentation, diagnosis, prevention and treatment of CMV infection in solid organ transplant recipients.

Wolff-Parkinson-White Syndrome
Wolff-Parkinson-White Syndrome samer kareem 1,814 Views • 2 years ago

Wolff-Parkinson-White (WPW) syndrome, an extra electrical pathway between your heart's upper and lower chambers causes a rapid heartbeat. The extra pathway is present at birth and fairly rare. The episodes of fast heartbeats usually aren't life-threatening, but serious heart problems can occur. Treatment can stop or prevent episodes of fast heartbeats. A catheter-based procedure (ablation) can permanently correct the heart rhythm problems. Most people with an extra electrical pathway experience no fast heartbeat. This condition, called Wolff-Parkinson-White pattern, is discovered only by chance during a heart exam. Although WPW pattern is often harmless, doctors might recommend further evaluation before children with WPW pattern participate in high-intensity sports.

Ureteral Stenting
Ureteral Stenting samer kareem 3,393 Views • 2 years ago

Ureteral stents are one of the most common devices used by urologists. They are placed with cystoscopic guidance in an operating room setting. Ureteral stents are used to relieve ureteral obstruction, promote ureteral healing following surgery, and to assist with ureteral identification during pelvic surgery. Ureteral stent placement is associated with some degree of morbidity in the majority of patients that ranges from generalized urinary discomfort to urinary tract infection or obstruction. Much of the morbidity is related to the biocompatibility of the materials used to fashion the stent and, to some extent, their design; unfortunately, the ideal stent has yet to be discovered.
