What is the best sleeping position? samer kareem 1,868 Views • 3 years ago

Your sleeping pose can have a major impact on your slumber—as well as your overall health. Poor p.m. posture could potentially cause back and neck pain, fatigue, sleep apnea, muscle cramping, impaired circulation, headaches, heartburn, tummy troubles, and even premature wrinkles

TALUS FRACTURE
TALUS FRACTURE samer kareem 1,589 Views • 3 years ago

A talus fracture is a break in one of the bones that forms the ankle. This type of fracture often occurs during a high-energy event, such as a car collision or a high-velocity fall. Because the talus is important for ankle movement, a fracture often results in significant loss of motion and function. In addition, a talus fracture that does not heal properly can lead to serious complications, including chronic pain. For this reason, many talus fractures require surgery.

Bilateral Sagittal Split osteotomy
Bilateral Sagittal Split osteotomy samer kareem 10,770 Views • 3 years ago

The bilateral sagittal split osteotomy is an indispensable tool in the correction of dentofacial abnormalities. The technique has been in practice since the late 1800s, but did not reach widespread acceptance and use until several modifications were described in the 1960s and 1970s. Those modifications came from a desire to make the procedure safer, more reliable, and more predictable with less relapse. Those goals continue to stimulate innovation in the field today and have helped the procedure evolve to be a very dependable, consistent method of correction of many types of malocclusion. The operative surgeon should be well versed in the history, anatomy, technical aspects, and complications of the bilateral sagittal split osteotomy to fully understand the procedure and to counsel the patient.

Blood Viscosity
Blood Viscosity samer kareem 1,461 Views • 3 years ago

When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

Aortic Valve Tumor
Aortic Valve Tumor samer kareem 1,986 Views • 3 years ago

Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.

Tracheotomy
Tracheotomy samer kareem 16,807 Views • 3 years ago

A tracheotomy or a tracheostomy is an opening surgically created through the neck into the trachea (windpipe) to allow direct access to the breathing tube and is commonly done in an operating room under general anesthesia. A tube is usually placed through this opening to provide an airway and to remove secretions from the lungs. Breathing is done through the tracheostomy tube rather than through the nose and mouth. The term “tracheotomy” refers to the incision into the trachea (windpipe) that forms a temporary or permanent opening, which is called a “tracheostomy,” however; the terms are sometimes used interchangeably.

IgA deficiency
IgA deficiency samer kareem 3,190 Views • 3 years ago

Selective immunoglobulin A deficiency (SIgAD) is a primary immunodeficiency disease and is the most common of the primary antibody deficiencies.[1] Total immunoglobulin A deficiency (IgAD) is defined as an undetectable serum immunoglobulin A (IgA) level at a value < 5 mg/dL (0.05 g/L) in humans. Partial IgAD refers to detectable but decreased IgA levels that are more than 2 standard deviations below normal age-adjusted means.[2, 3] IgAD is commonly associated with normal B lymphocytes in peripheral blood, normal CD4+ and CD8+ T cells, and, usually, normal neutrophil and lymphocyte counts. Anti-IgA autoantibodies of the IgG and/or IgE isotype may be present. Peripheral blood may also be affected by autoimmune cytopenias, eg, autoimmune thrombocytopenia,[4, 5] and patients may have other autoimmune phenomena. IgA was first identified by Graber and Williams in 1952; ten years later, the first patients with IgAD were described. IgAD is a heterogeneous disorder, and the results of intensive study are beginning to elucidate genetic loci and molecular pathogenesis that contribute to various subtypes of this disorder. Several lines of evidence suggest that, in many cases, IgAD and common variable immunodeficiency (CVID) have a common pathogenesis, which is discussed further in Pathophysiology. Other data indicate different genetic risk factors. Family studies show variable inheritance patterns. Familial inheritance of IgAD occurs in approximately 20% of cases,[6] and, within families, IgAD and CVID are associated.[7, 8] Many IgAD patients are asymptomatic (ie, "normal" blood donors) and are identified by finding a laboratory abnormality, without any apparent associated clinical disease. Some patients with IgAD may have the following associated conditions: (1) deficits in one or more immunoglobulin G (IgG) subclasses (this accounts for 20-30% of IgA-deficient patients, many of whom may have total IgG levels within the normal range) or (2) a deficient antibody response to pneumococcal immunization (specific polysaccharide antibody deficiency [SPAD]). Some patients with IgAD later develop CVID, and family members of patients with CVID may have only selective IgAD. Characterization of the receptor for the transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI), encoded by the gene TNFRSF13B ( tumor necrosis factor receptor superfamily member 13B), suggests that people with the C104, A181E, and ins204A variants may be at risk for IgAD that progresses to CVID.[9] Primary IgAD is permanent, and below-normal levels have been noted to remain static and persist after 20 years of observation.[10] A recent report documents a rare case of reversion.[11] Environmental factors such as drugs or infections can cause IgAD, but this form is reversible in more than half the cases (see Causes). Although individuals with IgAD have largely been considered healthy, recent studies indicate a higher rate of symptoms. A 20-year follow-up study that compared 204 healthy blood donors with incidentally identified IgAD to 237 healthy subjects with normal IgA levels demonstrated that 80% of IgAD donors and 50% of control subjects had episodes of infections, drug allergy, or autoimmune or atopic disease. Severe respiratory tract infections occurred in 26% of IgAD subjects, in 24% of subjects with decreased IgA levels, and in 8% of control subjects; however, the incidence of life-threatening infections was not increased. IgAD is more common in adult patients with chronic lung disease than in healthy age-matched control subjects.[12] Patients with IgAD are at some increased risk of developing severe reactions after receiving blood products.[13, 14, 15] IgG anti-IgA antibodies may cause severe transfusion reactions if patients with IgAD are given whole blood; therefore, IgA-poor blood or washed red cells are preferred for those patients. IgA-deficient patients with immunoglobulin E (IgE)–class anti-IgA antibodies are at risk for anaphylaxis if they receive blood or intravenous immunoglobulin, but this situation is extremely rare. Individuals with such an unusual profile should receive only low IgA intravenous immunoglobulin preparations. However, caution must be used when administering IGIV to patients with IgAD if their anti-IgA status is unknown. A history devoid of previous blood product administration does not exclude the possibility of anti-IgA antibodies or adverse reactions. Fortunately, appropriate precautions can significantly reduce morbidity (see Treatment). Blood banks can use a simple ELISA screening approach to establish an IgAD blood donor poo

Pathophysiology of Pulmonary Arterial Hypertension (PAH)
Pathophysiology of Pulmonary Arterial Hypertension (PAH) samer kareem 1,844 Views • 3 years ago

Pulmonary hypertension is a type of high blood pressure that affects the arteries in your lungs and the right side of your heart. In one form of pulmonary hypertension, tiny arteries in your lungs, called pulmonary arterioles, and capillaries become narrowed, blocked or destroyed. This makes it harder for blood to flow through your lungs, and raises pressure within your lungs' arteries. As the pressure builds, your heart's lower right chamber (right ventricle) must work harder to pump blood through your lungs, eventually causing your heart muscle to weaken and fail. Some forms of pulmonary hypertension are serious conditions that become progressively worse and are sometimes fatal. Although some forms of pulmonary hypertension aren't curable, treatment can help lessen symptoms and improve your quality of life. Pulmonary hypertension care at Mayo Clinic
