Lower Extremity Occlusive Disease
Lower Extremity Occlusive Disease samer kareem 1,313 Views • 2 years ago

Claudication, which is defined as reproducible ischemic muscle pain, is one of the most common manifestations of peripheral arterial occlusive disease (PAOD) caused by atherosclerosis. Claudication occurs during physical activity and is relieved after a short rest. Pain develops because of inadequate blood flow. Examination of a patient with claudication should include a complete lower-extremity evaluation and pulse examination, including measuring segmental pressures. Attempt to palpate pulses from the abdominal aorta to the foot, with auscultation for bruits in the abdominal and pelvic regions. When palpable pulses are not present, a handheld Doppler device may be used to assess circulation.

Insulin, Glucose samer kareem 10,619 Views • 2 years ago

This hormone, insulin, causes the liver to convert more glucose into glycogen (this process is called glycogenesis), and to force about 2/3 of body cells (primarily muscle and fat tissue cells) to take up glucose from the blood through the GLUT4 transporter, thus decreasing blood sugar.

How Penile Implants Work
How Penile Implants Work Mohamed Ibrahim 35,602 Views • 2 years ago

What Happens During an Erection?
In order to attain an erection, messages from the brain and other sense organs trigger the arteries of the penis to dilate. This allows an increased amount of blood to flow into three columns of spongy tissue in the penis.

As the arteries supplying blood to the corpus spongiosum and to the two larger columns, the corpus cavernosa, become filled with blood; the penis grows and becomes rigid. Pressure of the engorged tissue against the veins in the penis effectively traps blood within the penis until climax is reached or the sensation wanes.

What Are Penile Implants?
Impotence, or the inability to attain or maintain an erection, can be caused by a disruption at any stage in this process. Several types of penile implants are available that create an artificial erection. Two common types of implants are the semi-rigid malleable rod and the inflatable implant.

•The semirigid malleable rod is usually made of plastic with a core of flexible wire. These rods can be bent down to conceal the penis under clothing or raised to form an artificial erection.


•The inflatable implant is more complex and involves several working parts: a reservoir of fluid that is implanted into the abdomen, a pump system located in the scrotal sac near the testes, and two inflatable cylinders.
How Penile Implants Help Erectile Fuctioning
In order to attain an erection, the scrotal pump must be squeezed repeatedly to propel fluid into the penile cylinders. When an erection is no longer desired, a release valve is pressed on the side of the pump and the cylinders deflate.
Before Having Penile Implant Surgery
Persons considering these types of implants should speak with their physician or healthcare professional about possible risks and complications.

Rhabdomyolysis Video
Rhabdomyolysis Video Doctor 7,583 Views • 2 years ago

Rhabdomyolysis is a condition in which damaged skeletal muscle (Ancient Greek: rhabdomyo-) tissue breaks down rapidly (Greek –lysis). This damage may be caused by physical (e.g. crush injury), chemical, or biological factors. Breakdown products of damaged muscle cells are released into the bloodstream; some of these, such as the protein myoglobin, are harmful to the kidney and may lead to kidney dysfunction. The severity of the symptoms (which may include muscle pains, vomiting and confusion) depends on the extent of the muscle damage, and whether kidney failure develops. The mainstay of treatment is generous intravenous fluids, but could include dialysis or hemofiltration.

Rhabdomyolysis and its complications are significant problems for those injured in disasters such as earthquakes and bombing. Relief efforts in areas struck by earthquakes often include medical teams with skills and equipment for treatment of survivors with rhabdomyolysis. The disease and its mechanisms were first fully elucidated during the Blitz of London in 1941.

Rotator cuff pain commonly causes local swelling and tenderness in the front of the shoulder. You may have pain and stiffness when you lift your arm. There may also be pain when the arm is lowered from an elevated position. Beginning symptoms may be mild. Patients frequently do not seek treatment at an early stage. These symptoms may include: Minor pain that is present both with activity and at rest Pain radiating from the front of the shoulder to the side of the arm Sudden pain with lifting and reaching movements Athletes in overhead sports may have pain when throwing or serving a tennis ball As the problem progresses, the symptoms increase: Pain at night Loss of strength and motion Difficulty doing activities that place the arm behind the back, such as buttoning or zippering If the pain comes on suddenly, the shoulder may be severely tender. All movement may be limited and painful.

Automated External Defibrillator
Automated External Defibrillator Doctor 10,380 Views • 2 years ago

An automated external defibrillator or AED is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient,[1] and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm. The first AED was originally designed and created by American biomedical engineer Joshua L. Koelker and Italian emergency medical professional Jordan M. Blondino to allow defibrillation in common public places. AEDs are designed to be simple to use for the layman, and the use of AEDs is taught in many first aid, first responder, and basic life support (BLS) level CPR classes.

Diplegic Gait Demonstration

The patient has spasticity in the lower extremities greater than the upper extremities. The hips and knees are flexed and adducted with the ankles extended and internally rotated. When the patient walks both lower extremities are circumducted and the upper extremities are held in a mid or low guard position. This type of gait is usually seen with bilateral periventricular lesions. The legs are more affected than the arms because the corticospinal tract axons that are going to the legs are closest to the ventricles.

Shoulder Nerve injury
Shoulder Nerve injury samer kareem 2,945 Views • 2 years ago

The shoulder and arm receives its nerve supply through the brachial plexus. The brachial plexus is a complex network of nerves which come out of the neck, passes down to the front of the shoulder and then splits into many separate nerves to travel to different muscles and parts of the skin. Normally an arm movement is produced by initially thinking of the movement, then a message passes from the brain, down through the spinal cord to the appropriate nerve. Then the instruction to move is conveyed along the nerve to the specific arm muscle which then contracts and moves the arm.

Vascular Access Graft
Vascular Access Graft samer kareem 1,294 Views • 2 years ago

A surgeon creates an arteriovenous fistula by making a connection between an artery (which carries blood away from the heart) and a vein (which carries blood back to the heart). This artificial connection allows the vein to become larger and for the walls of the vein to thicken, a process termed maturation. A mature fistula makes it easier for the vein to be punctured repeatedly for dialysis. Maturation typically takes three to six months to occur, but in rare cases, can take up to a year. This makes advance planning for an arteriovenous fistula important. When a patient is felt to be approximately a year away from requiring dialysis, the patient should be referred for evaluation for possible creation of an arteriovenous fistula.
