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.
A detailed description of the approach to a use of bleeding disorders. This presentation includes the causes, history, clinical features and diagnosis of specific bleeding disorders. These include Haemophilia, DIC, Von Willebrand Disease and others. The final differentiation is often made on the basis of the Prothrombin Time, activated Partial thromboplastin time and platelet count.
This surgical animation is for patient education and describes a laparoscopic colectomy, which is a type of minimally invasive surgery for colon cancer. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Instead of a big incision, the surgeon makes a few small cuts (0.5-1 centimeters) in the abdominal cavity to insert a surgical camera and instruments and perform the operation. A slightly bigger incision, about 3.5 centimeters wide, is made to remove the tumor.
When compared to traditional open surgery, laparoscopic colectomy can result in much less pain and swifter recovery. Depending on the procedure, most laparoscopic colectomy patients leave the hospital and return to normal activities more quickly than patients recovering from open surgery.
Colorectal cancer is the second leading cause of cancer death in the United States.

Bone cancer symptoms. Possible symptoms of bone cancer include: Bone pain: Pain is the most common sign of bone cancer, and may become more noticeable as the tumor grows. Bone pain can cause a dull or deep ache in a bone or bone region (e.g., back, pelvis, legs, ribs, arms).
Colorectal surgeon Conor Delaney, MD, explains laparoscopic surgery for colon cancer, including how it works and what patients can typically expect before, during, and after the procedure.

A bone marrow biopsy is part of a bone marrow test that takes a sample of your solid bone tissue. This test looks for abnormalities in your blood cells and signs of any diseases. You can request anesthesia or a sedative before the biopsy, and manage any pain afterward with over-the-counter medications.
