Hypertrophic Cardiomyopathy
Hypertrophic Cardiomyopathy samer kareem 41,438 Views • 3 years ago

Hypertrophic cardiomyopathy (HCM) is very common and can affect people of any age. It affects men and women equally. It is a common cause of sudden cardiac arrest in young people, including young athletes. Hypertrophic cardiomyopathy occurs if heart muscle cells enlarge and cause the walls of the ventricles (usually the left ventricle) to thicken. The ventricle size often remains normal, but the thickening may block blood flow out of the ventricle. If this happens, the condition is called obstructive hypertrophic cardiomyopathy. Sometimes the septum, the wall that divides the left and right sides of the heart, thickens and bulges into the left ventricle. This can block blood flow out of the left ventricle. Then the ventricle must work hard to pump blood. Symptoms can include chest pain, dizziness, shortness of breath, or fainting. Hypertrophic cardiomyopathy also can affect the heart's mitral valve, causing blood to leak backward through the valve. Sometimes, the thickened heart muscle doesn't block blood flow out of the left ventricle. This is referred to as non-obstructive hypertrophic cardiomyopathy. The entire ventricle may thicken, or the thickening may happen only at the bottom of the heart. The right ventricle also may be affected. In both obstructive and non-obstructive HCM, the thickened muscle makes the inside of the left ventricle smaller, so it holds less blood. The walls of the ventricle may stiffen, and as a result, the ventricle is less able to relax and fill with blood.

Replantation after amputation of 5 fingers
Replantation after amputation of 5 fingers samer kareem 18,478 Views • 3 years ago

Since the first replant more than 50 years ago, thousands of severed body parts have been reattached, preserving the quality of life for thousands of patients through improved function and appearance that the void remaining after amputation cannot provide. Ronald Malt performed the first replantation on May 23, 1962 at Massachusetts General Hospital on a 12-year-old boy who had his right arm amputated in a train accident. [1, 2] This amputation occurred at the level of the humeral neck.

Testicular Torsion
Testicular Torsion samer kareem 9,082 Views • 3 years ago

Testicular torsion occurs when a testicle rotates, twisting the spermatic cord that brings blood to the scrotum. The reduced blood flow causes sudden and often severe pain and swelling. Testicular torsion is most common between ages 12 and 16, but it can occur at any age, even before birth. Testicular torsion usually requires emergency surgery. If treated quickly, the testicle can usually be saved. But when blood flow has been cut off for too long, a testicle might become so badly damaged that it has to be removed.

Head to Toe Assesment
Head to Toe Assesment samer kareem 28,893 Views • 3 years ago

A nursing student performs a complete head-to-toe assessment on a volunteer. The recording covers vital signs, BMI and vision checks, then systematic inspection and palpation from head and sinuses through the body systems to the spine and neck. Running about twenty-eight minutes, it is a full worked example for examination practice.

Live Rhinoplasty
Live Rhinoplasty samer kareem 93,971 Views • 3 years ago

Rhinoplasty enhances facial harmony and the proportions of your nose. It can also correct impaired breathing caused by structural defects in the nose. Rhinoplasty surgery can change: Nose size in relation to facial balance Nose width at the bridge or in the size and position of the nostrils Nose profile with visible humps or depressions on the bridge Nasal tip that is enlarged or bulbous, drooping, upturned or hooked Nostrils that are large, wide, or upturned Nasal asymmetry If you desire a more symmetrical nose, keep in mind that everyone’s face is asymmetric to some degree. Results may not be completely symmetric, although the goal is to create facial balance and correct proportion.

Menstrual cycle

Cardiovascular disease (CVD) is a general term that describes a disease of the heart or blood vessels. Blood flow to the heart, brain or body can be reduced as the result of a blood clot (thrombosis), or by a build-up of fatty deposits inside an artery that cause the artery to harden and narrow (atherosclerosis).

Henoch--Schönlein Purpura samer kareem 22,537 Views • 3 years ago

An antecedent upper respiratory infection is present in 50% of patients. Abdominal pain is a presenting symptom in 1 0-15% of patients. The skin lesions are symmetric, involve dependent parts of the body, and classically progress from an erythematous, macular rash to papular purpura. The joints and kidneys are also commonly involved

Laparoscopic Orchiopexy
Laparoscopic Orchiopexy samer kareem 13,028 Views • 3 years ago

Laparoscopy seems to offer a safe and reliable diagnostic and therapeutic option to patients with impalpable testes. Intra-abdominal dissection allows more testes to be brought down to the scrotum. The procedure is best viewed as laparoscopy-assisted, as Orchidopexy has to be done in a conventional manner.

Romberg's Test samer kareem 18,272 Views • 3 years ago

A patient who has a problem with proprioception can still maintain balance by using vestibular function and vision. In the Romberg test, the standing patient is asked to close his or her eyes. A loss of balance is interpreted as a positive Romberg's test.

Cremasteric reflex test
Cremasteric reflex test samer kareem 67,260 Views • 3 years ago

-The cremasteric reflex test is considered positive if there is elevation of the testis in response to stroking the upper inner thigh. This reaction is typically absent in testicular torsion and boys under the age of 6 months. Although not completely reliable in older boys and adults, an absent cremasteric reflex is highly suggestive of torsion. Patients with epididymitis usually have a normal cremasteric reflex, with pain and swelling isolated to
