In this condition, the body retains water instead of excreting it normally in urine. This process upsets the body's balance of minerals called electrolytes, especially sodium. Symptoms can vary depending on how rapidly the condition develops. In some cases, nausea and vomiting, headache, confusion, weakness, and fatigue may be experienced. Treatments include fluid restriction and, possibly, medications to adjust electrolyte balance. Underlying conditions also need treatment.
Open heart (coronary artery bypass, or CABG) surgery is performed in order to reroute, or "bypass," blood around blocked arteries, thereby improving the supply of oxygen-rich blood to the heart. Surgeons usually use an artery from the chest wall to construct the "detour" around the blocked part of the artery. Veins from the legs are also used.

Neurogenic shock is a distributive type of shock resulting in low blood pressure, occasionally with a slowed heart rate, that is attributed to the disruption of the autonomic pathways within the spinal cord. It can occur after damage to the central nervous system such as spinal cord injury.
A subdural hematoma is most often the result of a severe head injury. This type of subdural hematoma is among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury and may lead to death. Subdural hematomas can also occur after a minor head injury. The amount of bleeding is smaller and occurs more slowly. This type of subdural hematoma is often seen in older adults. These may go unnoticed for many days to weeks, and are called chronic subdural hematomas. With any subdural hematoma, tiny veins between the surface of the brain and its outer covering (the dura) stretch and tear, allowing blood to collect. In older adults, the veins are often already stretched because of brain shrinkage (atrophy) and are more easily injured.
Bipolar disorder, formerly called manic depression, is a mental health condition that causes extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). When you become depressed, you may feel sad or hopeless and lose interest or pleasure in most activities. When your mood shifts to mania or hypomania (less extreme than mania), you may feel euphoric, full of energy or unusually irritable. These mood swings can affect sleep, energy, activity, judgment, behavior and the ability to think clearly. Episodes of mood swings may occur rarely or multiple times a year. While most people will experience some emotional symptoms between episodes, some may not experience any. Although bipolar disorder is a lifelong condition, you can manage your mood swings and other symptoms by following a treatment plan. In most cases, bipolar disorder is treated with medications and psychological counseling (psychotherapy).
Thyroid nodules increase with age and are present in almost 10% of the adult population. Autopsy studies reveal the presence of thyroid nodules in 50% of the population, so they are fairly common. 95% of solitary thyroid nodules are benign, and therefore, only 5% of thyroid nodules are malignant.
The pain is frequently severe and is described as throbbing or pulsating. Nausea is common, and many migraine patients have a watering eye, a running nose, or congestion. If these symptoms are prominent, they may lead to a misdiagnosis of sinus headaches.
Macrobiopsy of breast lesions is a complicated procedure when performed with vacuum assisted biopsy tools. The Spirotome is a hand-held needle set that doesn't need capital investment, is ready to use and provides tissue samples of high quality in substantial amounts. In this way quantitative molecular biology is possible with one tissue sample. The Coramate is an automated version of this direct and frontal technology.
