Angina results from a reduction in the oxygen supply/demand ratio. Therefore, in order to alleviate the pain, it is necessary to improve this ratio. This can be done either by increasing blood flow (which increases oxygen delivery or supply), or by decreasing oxygen demand (i.e., by decreasing myocardial oxygen consumption).

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4. Heart murmurs are generated by turbulent flow of blood, which may occur inside or outside the heart. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency (regurgitation), which allows backflow of blood when the incompetent valve closes with only partial effectiveness. Different murmurs are audible in different parts of the cardiac cycle, depending on the cause of the murmur.
The Ortolani method is an examination method that identifies a dislocated hip that can be reduced into the socket (acetabulum). Ortolani described the feeling of reduction as a “Hip Click” but the translation from Italian was interpreted a sound instead of a sensation of the hip moving over the edge of the socket when it re-located. After the age of six weeks, this sensation is rarely detectable and should not be confused with snapping that is common and can occur in stable hips when ligaments in and around the hip create clicking noises. When the Ortolani test is positive because the hip is dislocated, treatment is recommended to keep the hip in the socket until stability has been established
The vagina is the most delicate and sensitive part of every woman’s body. Naturally female vagina appears to be darker compared to the complexion of other parts of the body. Hence, it is every woman’s dream to have a white complexioned vagina just like their body skin.

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.
These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. ... Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s.
Idiopathic thrombocytopenic purpura (ITP) is a disorder that can lead to easy or excessive bruising and bleeding. The bleeding results from unusually low levels of platelets — the cells that help blood clot. Idiopathic thrombocytopenic purpura, which is also called immune thrombocytopenia, affects children and adults. Children often develop ITP after a viral infection and usually recover fully without treatment. In adults, the disorder is often long term. If you don't have signs of bleeding and your platelet count isn't too low, you may not need any treatment. In rare cases, the number of platelets may be so low that dangerous internal bleeding occurs. Treatment options are available.
Your body's immune system protects you from disease and infection. But if you have an autoimmune disease, your immune system attacks healthy cells in your body by mistake. Autoimmune diseases can affect many parts of the body. No one is sure what causes autoimmune diseases. They do tend to run in families. Women - particularly African-American, Hispanic-American, and Native-American women - have a higher risk for some autoimmune diseases. There are more than 80 types of autoimmune diseases, and some have similar symptoms. This makes it hard for your health care provider to know if you really have one of these diseases, and if so, which one. Getting a diagnosis can be frustrating and stressful. Often, the first symptoms are fatigue, muscle aches and a low fever. The classic sign of an autoimmune disease is inflammation, which can cause redness, heat, pain and swelling. The diseases may also have flare-ups, when they get worse, and remissions, when symptoms get better or disappear. Treatment depends on the disease, but in most cases one important goal is to reduce inflammation. Sometimes doctors prescribe corticosteroids or other drugs that reduce your immune response.
