The age at which one should first have a prostate cancer screening has been debated. The recommendations of the American Cancer Society are for all patients over the age of 50 to undergo digital rectal examination and PSA testing.SA Testing for Older Men. Prostate cancer is a disease that is associated with a higher incidence amongst the elderly. Autopsy studies show that up to 80% of 80-year-old men are found to have prostate cancer.
The brain and spinal cord are surrounded by a clear fluid called cerebrospinal fluid (CSF). This fluid is produced and stored in cavities in the brain called ventricles. It circulates around the brain, moving from ventricle to ventricle.The purposes of the fluid are to cushion and protect the brain and spinal cord, to supply them with nutrients, and to remove some of their waste products.PH is different than other types of hydrocephalus in that it develops slowly over time. The drainage of CSF is blocked gradually, and the excess fluid builds up slowly. The slow enlargement of the ventricles means that the fluid pressure in the brain may not be as high as in other types of hydrocephalus.
Cerebrospinal fluid (CSF) bathes the brain and is contained within a lining around the brain called the dura. These intracranial structures (structures within the brain cavity) are also separated from the sinuses by bone. When there is a hole in the dura and bone, CSF can then leak into the sinuses and cause a CSF leak. CSF leak as a result of trauma to the head usually is managed with placement of a lumbar drain and bed rest. A lumbar drain is a small tubing placed in the back that allows drainage of small amounts of CSF. This allows diversion of the brain fluid to minimize pressure through any injured areas so that they can heal.
