Blocked Arteries in Legs

This video: Claudication is pain caused by too little blood flow, usually during exercise. Sometimes called intermittent claudication, this condition generally affects the blood vessels in the legs, but claudication can affect the arms, too. At first, you'll probably notice the pain only when you're exercising, but as claudication worsens, the pain may affect you even when you're at rest. Although it's sometimes considered a disease, claudication is technically a symptom of a disease. Most often, claudication is a symptom of peripheral artery disease, a potentially serious but treatable circulation problem in which the vessels that supply blood flow to your legs or arms are narrowed. Fortunately, with treatment, you may be able to maintain an active lifestyle without pain.

Polycythemia
Polycythemia samer kareem 2,718 Views • 2 years ago

Polycythemia vera (pol-e-sigh-THEE-me-uh VEER-uh) is a slow-growing type of blood cancer in which your bone marrow makes too many red blood cells. Polycythemia vera may also result in production of too many of the other types of blood cells — white blood cells and platelets. These excess cells thicken your blood and cause complications, such as such as a risk of blood clots or bleeding. Polycythemia vera isn't common. It usually develops slowly, and you may have it for years without noticing signs or symptoms. Often, polycythemia vera is found during a blood test done for some other reason. Without treatment, polycythemia vera can be life-threatening. However, with proper medical care, many people experience few problems related to this disease. Over time, there's a risk of progressing to more-serious blood cancers, such as myelofibrosis or acute leukemia.

Rheumatoid Arthritis Treatment
Rheumatoid Arthritis Treatment samer kareem 1,988 Views • 2 years ago

This video, Rheumatoid arthritis is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition also can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels. An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well. While new types of medications have improved treatment options dramatically, severe rheumatoid arthritis can still cause physical disabilities.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,364 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

Adrenoleukodystrophy explained.
Adrenoleukodystrophy explained. samer kareem 4,268 Views • 2 years ago

X-linked adrenoleukodystrophy is a genetic disorder that occurs primarily in males. It mainly affects the nervous system and the adrenal glands, which are small glands located on top of each kidney. In this disorder, the fatty covering (myelin) that insulates nerves in the brain and spinal cord is prone to deterioration (demyelination), which reduces the ability of the nerves to relay information to the brain. In addition, damage to the outer layer of the adrenal glands (adrenal cortex) causes a shortage of certain hormones (adrenocortical insufficiency). Adrenocortical insufficiency may cause weakness, weight loss, skin changes, vomiting, and coma.

Digoxin mechanism of action
Digoxin mechanism of action samer kareem 4,167 Views • 2 years ago

Digoxin is used to treat heart failure, usually along with other medications. It is also used to treat a certain type of irregular heartbeat (chronic atrial fibrillation). Treating heart failure may help maintain your ability to walk and exercise and may improve the strength of your heart. Treating an irregular heartbeat can decrease the risk for blood clots, an effect that may reduce your risk for a heart attack or stroke.

Bunion Hallux Abductor Valgus Surgery
Bunion Hallux Abductor Valgus Surgery Scott 16,956 Views • 2 years ago

A "Hallux Valgus" or "Hallux Abducto-Valgus" deformity, is commonly referred to as a "Bunion." This describes a pathological condition involving the position of the "hallux" in relation to the first metatarsal.

A bunion deformity can clinically present with a variety of characteristics. The foot itself may present with a wide splaying of the forefoot and a painful bump on the medial aspect of the first metatarsal phalangeal joint. In addition, the hallux may be abducted from the midline of the body, with a valgus rotation in the frontal plane.

A radiographic analysis of a bunion deformity in the Anterior/Posterior or Dorsal/Plantar view will reveal a variety of pathological components. Most notably so, is the exaggerated inter-metatarsal angle between the first and second metatarsal. This may be accompanied by a displacement of the first metatarsal from its position over the sesamoids, such that the metatarsal demonstrates a medial alignment away from the sesamoids which lie to the lateral side.

In some cases, the proximal articular set angle at the head of the first metatarsal may be off-set. This "PASA" is one of the factors which determines the position of the proximal phalanx on the metatarsal during movement as well as at rest.

Although conservative care may involve shoe modifications, padding, strapping, and custom orthosis; surgical reconstruction may be required to alleviate painful and immobilizing bunion conditions.

Soft tissue components of the bunion deformity are primarily addressed by means of a capsular modification, as well as a tenotomy of the adductor tendon at its insertion on the base of the proximal phalanx. The fibular sesamoid may be repositioned by a release of the surrounding ligaments.

Surgical management of the bone or osseous components of a bunion deformity will commonly include an osteotomy and correction to re-establish a more functional position of the first metatarsal within the forefoot. This capital fragment of bone is held in place with hardware fixation in order to secure a proper alignment during the healing phase, thus allowing the hallux to return to a more functionally useful position in the sagittal plane.

How Does Foam Sclerotherapy Treat Varicose Veins?
How Does Foam Sclerotherapy Treat Varicose Veins? samer kareem 2,757 Views • 2 years ago

Sclerotherapy is a procedure used to eliminate varicose veins and spider veins. Sclerotherapy involves an injection of a solution (generally a salt solution) directly into the vein. The solution irritates the lining of the blood vessel, causing it to collapse and stick together and the blood to clot.Sep 17, 2016

Patient 65-year-old of age who comes to the medical consultation with pain moderated pain in the right hypochondrium of “several years of evolution” but that it increased one week ago. Also, she shows pain in the umbilical region of “many years of evolution”, that is supported according to the patient - in a constant way.rnTo the examination, we observe an umbilical hernia, apparently divided into two parts. The hernia of the external region measures 25.1 centimeters x 18.0 centimeters and the one that occupies the average region measures 12.0 centimeters x 10.0 centimeters.rnPatient who comes to the medical consultation with moderated pain in the right hypochondrium of one year of evolution but it increased one week ago after eat duck.rnIn the ultrasound scan of the region of the right hypochondrium (patient came having breakfast, that is to say, without previous preparation ) we can observe the liver of 123.8 millimeters high, as well as the porta vein with a diameter of 7.3 millimeters.rnOn having observed the Gallbladder, we think that a side wall is increased in 2.7 mm (hyperechogenic) with several “echogenics points” in the interior (”Biliary Mud”).

The measurements of the gallbladder were: 39.0 x 17.4 millimeters.rnWe can appreciates an echogenic image in the interior that it would make think about stone. The stones are identified as echogenic foci casting acoustic shadowing but but this image did not appear and a re-evaluation is decided in 15 days.

Acalculous cholecystopathy which means disease or condition of the gallbladder without the presence of gallstones. You might also call it functional gallbladder disorder or impaired gallbladder emptying. Some causes may be chronic inflammation, a problem with the smooth muscles of the gallbladder or the muscle of the Sphincter of Oddi being too tight.

REMEMBER:
Umbilical hernia is a congenital malformation, especially common in infants of African descent, and more frequent in boys. An Acquired umbilical hernia directly results from increased intra-abdominal pressure and are most commonly seen in obese individuals.
Presentation:A hernia is present at the site of the umbilicus (commonly called a navel, or belly button) in the newborn; although sometimes quite large, these hernias tend to resolve without any treatment by around the age of 5 years. Obstruction and strangulation of the hernia is rare because the underlying defect in the abdominal wall is larger than in an inguinal hernia of the newborn. The size of the base of the herniated tissued is inversely correlated with risk of strangulation (i.e. narrow base is more likely to strangulate).
Babies are prone to this malformation because of the process during fetal development by which the abdominal organs form outside the abdominal cavity, later returning into it through an opening which will become the umbilicus.
Differential diagnosisrnImportantly this type of hernia must be distinguished from a paraumbilical hernia which occurs in adults and involves a defect in the midline near to the umbilicus, and from omphalocele.
