Benign hematology
|
|
Benign hematology The study and treatment of blood, blood-forming tissues, and blood-related diseases that are not life-threatening.
RELATED TERMS--------------------------------------
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
SIMILAR TERMS--------------------------------------
Benicar
Benicar is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): olmesartan medoxomil.
Benicar hct
Benicar hct is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): hydrochlorothiazide; olmesartan medoxomil.
Benign
Non-malignant; not life-threatening.
Benign familial tremor
An inherited disorder that causes a slow tremor in the hands, head and voice. It may affect only one side of the body, be worse when moving than when resting and worsen with age.
Benign intracranial hypertension
Increased pressure within the brain in the absence of a tumor. Symptoms may include headache, nausea, vomiting, pulsating intracranial noises, singing in the ears, double vision, loss of visual accuracy, and even blindness. It is most common in women between the ages of 20 and 50. The cause is usually not known. The condition is associated sometimes with the use of tetracycline, nalidixic acid, nitrofurantoin, phenytoin, lithium, and amiodarone, and the overuse of vitamin A. Diagnosis is by brain imaging and lumbar puncture. Drugs to reduce cerebrospinal fluid production or hyperosmotic drugs may be used to reduce fluid buildup. Excess cerebrospinal fluid may be removed by repeated spinal taps, shunting or a type of surgery called optic nerve sheath fenestration that allows the excess fluid to escape. Steroids may be prescribed to reduce swelling of brain tissue. Benign intracranial hypertension is also called pseudotumor cerebri.
Benign lymphoreticulosis
Cat scratch disease, a mild flu-like infection, with swollen lymph nodes (lymphadenitis) and mild fever of short duration, due to cat scratches, especially from kittens. There is usually a little bump (a papule) which may be pus-filled (a pustule) at the site of the scratch. The infection is self-limited and usually goes away by itself in a few weeks. It can also be treated with antibiotics, but it can cause a severe inflammation called bacillary angiomatosis in patients with weakened immune systems. A cat carrying the microbe does not show symptoms and it is not necessary to get rid of it. If someone in the household is at high risk, a test to detect the infection can be done and the cat can be treated. The disease is caused by a bacterium called Rochalimaea henselae, eventually reclassified as Bartonella henselae, named for Diane Hensel, a microbiologist. The disease has also been called regional lymphadenitis.
Benign melanoma
See: Melanoma, benign.
Benign paroxysmal positional vertigo (BPPV)
A balance disorder that results in the sudden onset of dizziness, spinning, or vertigo when moving the head.
Benign prostatic hyperplasia
Abbreviated BPH. A noncancerous prostate problem in which the normal elements of the prostate gland grow in size and number. Their sheer bulk may compress the urethra, which courses through the center of the prostate, impeding the flow of urine from the bladder through the urethra to the outside. This leads to urine retention and the need for frequent urination. If BPH is severe, complete blockage can occur.
Benign prostatic hyperplasia (BPH)
An enlargement of the prostate caused by disease or inflammation. It is not cancer, but its symptoms are often similar to those of prostate cancer.
Benign prostatic hypertrophy
Enlargement or overgrowth of the prostate gland as a result of an increase in the number of its constituent cells.
Benign recurrent aseptic meningitis
Recurring meningitis without identifiable cause that leaves no residual damage to the nervous system. Benign recurrent aseptic meningitis is also called Mollaret meningitis.
Benign sleep myoclonus
A distinctive disorder of sleep in infancy characterized by rhythmic myoclonic jerks (sudden muscle contractions) which occur when the child is asleep and which stop when the child is awakened. Sleep myoclonus usually disappears after a few weeks, in most cases by 3 months of age, as the sleep patterns mature. Benign sleep myoclonus may be mistaken for epilepsy.
Benign tumor
An abnormal growth that is not cancer and does not spread to other areas of the body.
PREVIOUS AND NEXT TERMS--------------------------------------
Bulemia
See Bulimia.
Bulemarexia
Anorexia nervosa.
Body Dysmorphic Disorder (BDD)
Body dysmorphic disorder (BDD) is a mental disorder which involves a disturbed body image. The central feature of BDD is that persons who are afflicted with it are excessively dissatisfied with their body because of a perceived physical defect.
Bruise
A bruise or contusion or ecchymoses is a kind of injury, usually caused by blunt impact, in which the capillaries are damaged, allowing blood to seep into the surrounding tissue. Normally minor but painful, bruises can be serious, leading to hematoma, or can be associated with serious injuries, including fractures and internal bleeding. Minor bruises are easily recognized by their characteristic blue or purple color in the days following the injury.
Benign
Non-malignant; not life-threatening.
Benign hematology
Biomarker
A biochemical characteristic that can be used to measure the progress of disease or the effects of treatment.
Bone marrow
The body's `factory' for three types of blood cells: leukocytes (white blood cells) which help fight infection; erythrocytes (red blood cells) which carry oxygen throughout the body; and thrombocytes (platelets) which cause blood clotting.
Bone marrow aspiration
The removal and examination of bone marrow cells.
Bone marrow donor
A person who donates healthy bone marrow to a patient who has had high-dose cancer treatment. The patient is given the donor's healthy marrow during a bone marrow transplant.
Bone marrow harvest
A procedure to collect healthy bone marrow which will be stored and used in a future bone marrow transplant.
