The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The substances are filtered out from the body in the form of urine. Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra.
Bacterial meningitis is very serious and can be deadly. Death can occur in as little as a few hours. While most people with meningitis recover, permanent disabilities such as brain damage, hearing loss, and learning disabilities can result from the infection. There are several types of bacteria that can cause meningitis. Some of the leading causes of bacterial meningitis in the United States include Streptococcus pneumoniae, group B Streptococcus, Neisseria meningitidis, Haemophilus influenzae, and Listeria monocytogenes.
The cardiac cycle is the sequence of events that occurs when the heart beats. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body. There are two phases of the cardiac cycle. In the diastole phase, the heart ventricles are relaxed and the heart fills with blood
Acute mesenteric ischemia (AMI) is a syndrome caused by inadequate blood flow through the mesenteric vessels, resulting in ischemia and eventual gangrene of the bowel wall. Although relatively rare, it is a potentially life-threatening condition. Broadly, AMI may be classified as either arterial or venous. AMI as arterial disease may be subdivided into nonocclusive mesenteric ischemia (NOMI) and occlusive mesenteric arterial ischemia (OMAI); OMAI may be further subdivided into acute mesenteric arterial embolism (AMAE) and acute mesenteric arterial thrombosis (AMAT). AMI as venous disease takes the form of mesenteric venous thrombosis (MVT).
Throughout the body, there are several points at which blood vessels unite. The junctions are termed anastomoses. In the simplest sense, an anastomosis is any connection (made surgically or occurring naturally) between tube-like structures. Naturally occurring arterial anastomoses provide an alternative blood supply to target areas in cases where the primary arterial pathway is obstructed. They are most abundant in regions of the body where the blood supply may can be easily damaged or blocked (such as the joints or intestines). This article focuses on the arterial anastomotic networks of the upper limb.
Injuries and certain medical conditions can result in bleeding. This can trigger anxiety and fear, but bleeding has a healing purpose. Still, you need to understand how to treat common bleeding incidents, like cuts and bloody noses, as well as when to seek medical help.
A myringotomy is a procedure in which your doctor creates a small hole in the eardrum so fluids such as water, blood, or pus can drain out. In many cases, your doctor will put in a tube so it won't get backed up again. The tube, which will usually fall out on its own in about six to 18 months, lets air flow through and keeps the middle ear dry. Tubes also: Reduce pain Improve hearing Cut down on the number of infections your child may have
Like any syndrome, fetal alcohol syndrome (FAS) is a group of signs and symptoms that appear together and indicate a certain condition. In the case of FAS, the signs and symptoms are birth defects that result from a woman's use of alcohol during her pregnancy.
How do you know if you have pneumonia? They may include: Cough. You will likely cough up mucus (sputum) from your lungs. ... Fever. Fast breathing and feeling short of breath. Shaking and "teeth-chattering" chills. Chest pain that often feels worse when you cough or breathe in. Fast heartbeat. Feeling very tired or very weak. Nausea and vomiting.
Watch Spinal Stenosis Videos Spinal stenosis occurs when the spinal cord in the neck (cervical spine) or the spinal nerve roots in the lower back (lumbar spine) are compressed. Symptoms of lumbar stenosis often include leg pain (sciatica) and leg tingling, weakness, or numbness. Arm pain is a typical symptom of cervical spinal stenosis. For cervical spinal stenosis with myelopathy, difficulty with coordination often occurs. Stenosis treatment may include non-surgical options (exercise, anti-inflammatory medication, epidural injections, and activity modification) or back surgery.
What factors should I consider when deciding whether to have surgery? The following factors should be considered when deciding whether to have surgery: Your age—If you have surgery at a young age, there is a chance that prolapse will recur and may possibly require additional treatment. If you have surgery at an older age, general health issues and any prior surgery may affect the type of surgery that you have. Your childbearing plans—Ideally, women who plan to have children (or more children) should postpone surgery until their families are complete to avoid the risk of prolapse happening again after corrective surgery. Health conditions—Any surgical procedure carries some risk, such as infection, bleeding, blood clots in the legs, and problems related to anesthesia. Surgery may carry more risks if you have a medical condition, such as diabetes, heart disease, or breathing problems, or if you smoke or are obese. New problems—Surgery also may cause new problems, such as pain during sex, pelvic pain, or urinary incontinence.
A bone marrow biopsy removes a small amount of bone and a small amount of fluid and cells from inside the bone (bone marrow). A bone marrow aspiration removes only the marrow. These tests are often done to find the reason for many blood disorders and may be used to find out if cancer or infection has spread to the bone marrow. Bone marrow aspiration removes a small amount of bone marrow fluid and cells through a needle put into a bone. The bone marrow fluid and cells are checked for problems with any of the blood cells made in the bone marrow. Cells can be checked for chromosome problems. Cultures can also be done to look for infection. A bone marrow biopsy removes bone with the marrow inside to look at under a microscope. The aspiration (taking fluid) is usually done first, and then the biopsy.
