In healthy men and women, urine does not contain any blood that can be seen with the eye, called "gross blood," nor does it contain red blood cells that can be discovered with the aid of a microscope. The discovery of either gross or microscopic blood in urine is a sure indication of the need to examine and evaluate the patient to discover the cause of this abnormality. The conditions that can lead to either gross or microscopic blood in the urine are many and varied. In adults, a careful history to describe the details of the bloody urine, a physical examination and laboratory studies are the first step in unearthing the cause. Imaging with x-rays, ultrasound, CAT/MRI scans are the next step and will usually discover the cause. In adult women, infection of the bladder or kidneys, urinary stones, and tumors of the urinary bladder, kidneys are the most common causes. In adult men, enlargement and/or infection of the prostate, bladder infection and...

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease, is a rapidly progressive motor neuron disease affecting as many as 20,000-30,000 people in the United States. One of the most common neuromuscular diseases worldwide, ALS affects people of all races and ethnic backgrounds, typically between the ages of 40 and 60.
ALS attacks the nerve cells (motor neurons) that control voluntary movement and strength. Motor neurons are located in the spinal cord and brain. In ALS, motor neurons gradually die which interferes with muscle control and movement, ultimately leading to death. The cause of ALS is still unknown although research has identified a genetic risk factor in familial (inherited) cases of ALS which account for 5-10% of all ALS cases diagnosed.
