An animation of blood flow inside the hollow fiber of a hemofilter, or a dialyzer, and the flow of the dialysate in an opposite direction with increased extraction of waste and small molecules from the blood as the concentration of these molecules is reduced downstream and exposed to new dialysate.

Allergies, what causes them? This animated video reviews the pathophysiology of allergies, what causes them and why the symptoms occur. Food allergies, seasonal allergies and allergies to pollen all occur through a similar mechanism.

Thoracic outlet syndrome affects the space between the collarbone and first rib (thoracic outlet). Common causes include trauma, repetitive injuries, pregnancy, and anatomical defects, such as having an extra rib. Symptoms include pain in the shoulders and neck and numbness, weakness, and coldness in the fingers. Treatment involves physical therapy and pain relief. In rare cases, surgery may be needed to relieve the compression.

The lymphatic system is a network of specialized vessels (lymph vessels) throughout the body whose purpose is to collect excess lymph fluid with proteins, lipids, and waste products from the tissues. This fluid is then carried to the lymph nodes, which filter waste products and contain infection-fighting cells called lymphocytes. The excess fluid in the lymph vessels is eventually returned to the bloodstream. When the lymph vessels are blocked or unable to carry lymph fluid away from the tissues, localized swelling (lymphedema) is the result.

Elbow Exam - Orthopaedic OSCE - Clinical Skills - Dr Gill

The elbow examination is a core skill - in this video, we demonstrate how to perform an elbow EXAM for an Orthopaedic Clinical Skills OSCE, which should be one of the more accessible examination stations for medical students.

For a passing grade in your Clinical Skills OSCE, an elbow assessment should follow the LOOK, FEEL, MOVE approach

Initially looking for erythema, scars, swelling and position

Palpating the elbow - specifically the olecranon, medial and lateral epicondyles, and radial head for heat, oedema and crepitus

Finally assess range of movement with flexion and extension at the elbow, before determining for tennis and golfers' elbows

Watch further orthopaedic examinations for your OSCE revision:

------------

Please note that there is no ABSOLUTE way to perform a clinical examination. Different institutions and even clinicians will have differing degrees of variations - the aim is the effectively identify medically relevant signs.

However during OSCE assessments. Different medical schools, nursing colleges and other health professional courses will have their own preferred approach to a clinical assessment - you should concentrate on THEIR marks schemes for your assessments.

The examination demonstrated here is derived from Macleods Clinical Examination - a recognised standard textbook for clinical skills.

Colorectal cancer screening tests Screening is the process of looking for cancer in people who have no symptoms of the disease. Several tests can be used to screen for colorectal cancers. These tests can be divided into: Tests that can find both colorectal polyps and cancer: These tests look at the structure of the colon itself to find any abnormal areas. This is done either with a scope put into the rectum or with special imaging (x-ray) tests. Polyps found during these tests can be removed before they become cancerous, so these tests may prevent colorectal cancer. Because of this, these tests are preferred if they are available and you are willing to have them. Tests that mainly find cancer: These tests check the stool (feces) for signs of cancer. These tests are less invasive and easier to have done, but they are less likely to detect polyps.

Bone marrow is the soft, sponge-like material found inside bones. It contains immature cells known as hematopoietic or blood-forming stem cells. (Hematopoietic stem cells are different from embryonic stem cells. Embryonic stem cells can develop into every type of cell in the body.) Hematopoietic stem cells divide to form more blood-forming stem cells, or they mature into one of three types of blood cells: white blood cells, which fight infection; red blood cells, which carry oxygen; and platelets, which help the blood to clot. Most hematopoietic stem cells are found in the bone marrow, but some cells, called peripheral blood stem cells (PBSCs), are found in the bloodstream. Blood in the umbilical cord also contains hematopoietic stem cells. Cells from any of these sources can be used in transplants.

A clinical examination of the lower limbs is demonstrated in this physical-examination video, covering inspection, palpation, movement, and neurovascular checks of the legs. It follows the structured approach taught in medical school. A core study resource for students. Educational only — not medical advice.

Absence seizures involve brief, sudden lapses of consciousness. They're more common in children than adults. Someone having an absence seizure may look like he or she is staring into space for a few seconds. This type of seizure usually doesn't lead to physical injury. Absence seizures usually can be controlled with anti-seizure medications. Some children who have them also develop other seizures. Many children outgrow absence seizures in their teens.

If you use condoms perfectly every single time you have sex, they’re 98% effective at preventing pregnancy. But people aren’t perfect, so in real life condoms are about 85% effective — that means about 15 out of 100 people who use condoms as their only birth control method will get pregnant each year.

Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.
