  • Thrombosis is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. Alternatively, even when a blood vessel is not injured, blood clots may form in the body if the proper conditions present themselves. If the clotting is too severe and the clot breaks free, the traveling clot is now known as an embolus

  • Cardiovascular disease, including coronary heart disease, strokes and diseases of other arteries, is a major cause of early death and disability. For many years the major markers of disease risk have been well recognised: these include high blood cholesterol levels and smoking. But it has also been recognised that these markers do not account for all cardiovascular risk. Furthermore, treatments that are highly effective in altering these markers, for instance the ‘statin’ drugs used to lower cholesterol, do not remove risk entirely: typically they reduce it by about 30% or less.

  • A response is to amplify the change in the variable. This has a destabilizing effect, so does not result in homeostasis. Positive feedback is less common in naturally occurring systems than negative feedback, but it has its applications. For example, in nerves, a threshold electric potential triggers the generation of a much larger action potential. Blood clotting and events in childbirth are other types of positive feedback.

  • Serous or “body cavity fluids” are usually collected with aseptic technique by needle puncture and aspiration of the body cavity fluid. Methods for obtaining the specimen vary depending upon the site. Fluids are best collected into a dry container and submitted in the fresh state to the laboratory. 7 Adding 3-5 IU heparin/mL to a container prior to obtaining a bloody sample will usually inhibit clotting and not adversely affect morphology. If delay in transportation to the laboratory is unavoidable, most fluids may be kept refrigerated (4ºC) up to 72 hours.

  • What is thrombophilia? Thrombophilia is a condition where the blood forms clots more easily than normal, which can lead to unwanted blood clots in the body. There are different kinds of thrombophilia. What causes thrombophilia? Thrombophilia occurs if the normal balance of the clotting system is upset. There may be too much of a clotting factor, or too little of a factor that opposes clotting.

  • Although the part of our bodies most affected by air pollution is the respiratory system, the circulatory system can also be affected. Exposure to unhealthy levels of air pollutants can result in low oxygen levels in red blood cells, abnormal heart rhythms, and increased risks of blood clots and narrowing of blood vessels. These effects can lead to worsening of heart diseases such as heart failure and increased risks of heart attacks or strokes. The Pollutants Chart: Sources and Effects of Air Pollutants summarize the sources and health effects of criteria air pollutants.

  • When one thinks of illnesses and diseases that result from obesity, most people think of heart disease, high blood pressure, and diabetes. We refer to these as the big three. But the list is very long and includes: depression/social isolation, arthritis/back pain, pulmonary embolus (blood clots from the legs, thighs, to the lungs), gallbladder disease, sleep apnea, infertility in women, increased cancer risk in men and women, chronic lack of energy, etc. For over twenty years I have practiced medicine in New York City.

  • Estrogen therapy: Using estrogen to treat symptoms of change of life is known as estrogen therapy or menopausal hormone therapy. Estrogen treatment can reduce hot flashes, improve vaginal dryness, and help prevent the weakening of the bones (osteoporosis) that can happen with menopause. But the use of estrogen by itself increases a woman's risk of getting endometrial cancer in women who still have a uterus. Estrogen therapy also increases a woman's chance of developing serious blood clots and heart disease.

  • Conventional treatments of hemorrhagic cystitis are hyper-hydration, diuresis and bladder irrigation to wash out viral particles and clots, and to prevent retrograde infection to kidneys and post-renal failure due to urethral obstruction caused by clots. High titer γ- globulin to specific adenovirus serotype is also administrated. In particular, serotype 35 specific antibody was present only at a very low titer in pooled gamma globulin (Flomenberg et al., 1987).

  • Harrison's Internal Medicine Chapter 59. Bleeding and Thrombosis Bleeding and Thrombosis: Introduction The human hemostatic system provides a natural balance between procoagulant and anticoagulant forces. The procoagulant forces include platelet adhesion and aggregation and fibrin clot formation; anticoagulant forces include the natural inhibitors of coagulation and fibrinolysis. Under normal circumstances, hemostasis is regulated to promote blood flow; however, it is also prepared to clot blood rapidly to arrest blood flow and prevent exsanguination.

  • The central mechanism of DIC is the uncontrolled generation of thrombin by exposure of the blood to pathologic levels of tissue factor (Fig. 110-3). Simultaneous suppression of physiologic anticoagulant mechanisms and abnormal fibrinolysis further accelerate the process. Together these abnormalities contribute to systemic fibrin deposition in small and mid-sized vessels. The duration and intensity of the fibrin deposition can compromise the blood supply of many organs, especially the lung, kidney, liver, and brain, with consequent organ failure.
