Benign prostatic hypertrophy
|
|
Benign prostatic hypertrophy Enlargement or overgrowth of the prostate gland as a result of an increase in the number of its constituent cells.
RELATED TERMS--------------------------------------
Prostate
A male sex gland that produces a thick fluid which forms part of semen.
Gland
An organ that releases a chemical. Endocrine glands are ductless and secrete hormones directly into the bloodstream. Exocrine glands secrete externally, either through a tube or duct.
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 hematology
The study and treatment of blood, blood-forming tissues, and blood-related diseases that are not life-threatening.
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 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--------------------------------------
Biperiden
An antiparkinsonian substance.
Barbital
A hypnotic substance.
Benzyl
The hydrocarbon radical of benzyl alcohol and various other compounds.
Back pain
Acute or chronic pain located in the posterior regions of the trunk, including the thoracic, lumbar, sacral, or adjacent regions.
Bedwetting
Involuntary discharge of urine after the age at which urinary control should have been achieved; often used alone with specific reference to involuntary discharge of urine occurring during sleep at night (bed-wetting; nocturnal enuresis).
Benign prostatic hypertrophy
Blepharospasm
Excessive winking; tonic or clonic spasm of the orbicularis oculi muscle.
Baldness
Baldness (formally alopecia) is the state of lacking hair where it usually would grow, especially on the head. The most common form of baldness is a progressive hair-thinning condition that occurs in adult humans and many other ape species. Stress factors such as a regular lack of sufficient sleep may be able to accelerate the onset of hair loss in genetically prone individuals.
B lymphocyte
The precursors of antibody-forming plasma cells; these cells carry immunoglobulin and class II MHC (major histocompatibility complex) antigens on their surfaces.
B cell
The precursors of antibody-forming plasma cells; these cells carry immunoglobulin and class II MHC (major histocompatibility complex) antigens on their surfaces.
Basophil
A polymorphonuclear leukocyte., whose basophils granules contain heparin, histamine and other vasoactive amines. Within tissues, these cells are known as mast cells q.v.
