1. pertaining to or containing cysts.
2. pertaining to the urinary bladder or to the gallbladder.
cystic disease of breast fibrocystic disease of breast.
cystic fibrosis a hereditary disorder associated with widespread dysfunction of the exocrine glands, with accumulation of excessively thick and tenacious mucus and abnormal secretion of sweat and saliva; it is inherited as a recessive trait; both parents must be carriers. The cause is thought to be absence, insufficiency, or abnormality of some essential hormone or enzyme. Called also cystic fibrosis of the pancreas and mucoviscidosis.
Effects. The symptoms and severity vary widely. Although cystic fibrosis is congenital, it may not manifest itself significantly during the early weeks or months of life, or it may cause intestinal obstruction and perforation in the newborn. The chief cause of complications is the extremely thick mucus produced. Normal mucus bathes and protects internal surfaces, transports chemicals produced in one organ through intricate small ducts to another organ, and carries bacteria, dirt, and wastes to be eliminated from the body; thus it needs to flow easily. The mucus of cystic fibrosis, in contrast, is highly adhesive. Bacteria and other matter stick to it, and it in turn clogs the lungs and usually interferes with the flow of digestive enzymes from the pancreas to the small intestine.

In the lungs, the mucus blocks the bronchioles, creating breathing difficulties. Infection develops, thereby increasing obstruction of the air passages. Air becomes trapped in the lungs (emphysema), and scattered small areas eventually collapse (patchy atelectasis). Repeated infections follow, inflaming and damaging lung tissue and leading to chronic lung disease. The organism that produces infection in cystic fibrosis is almost always a staphylococcus, but other organisms may be present in more severe cases. About half of children with cystic fibrosis have lung-related symptoms.

When mucus prevents the pancreatic enzymes from reaching the duodenum (as in about 80 per cent of cystic fibrosis patients), digestion is hindered. Fats especially are poorly digested and absorbed. The child may have a voracious appetite, yet fail to grow normally or gain weight. There may be marked signs of malnutrition. The outstanding symptom associated with pancreatic enzyme deficiency is frequent bulky, fatty, and foul-smelling feces.

Between 5 and 10 per cent of cystic fibrosis babies are born with intestines obstructed by puttylike intestinal secretions (meconium ileus) and die unless the condition is diagnosed promptly and relieved by surgery within the first few days of life. Such relief does not protect the child against the other manifestations of cystic fibrosis, although these may not appear until later.

Because cysts and scar tissue on the pancreas were observed during autopsy when the disease was first being differentiated from other conditions, it was given the name cystic fibrosis of the pancreas. Although this term describes a secondary rather than primary characteristic, it has been retained.
Diagnosis. Sweat in cystic fibrosis is excessively salty. Collapse of cystic fibrosis patients from salt loss during a heat wave led to recognition of the sweat abnormality. The sweat chloride test remains the cornerstone of diagnosis of cystic fibrosis. In children, a sweat chloride level above 60 mEq/l indicates cystic fibrosis. Newborn infants do not produce sufficient sweat for the test, but it has been noted that older babies “taste salty” when kissed. Supporting evidence can confirm the sweat test finding.
Treatment. Under careful supervision by the health care team, parents are taught the principles of home treatment of cystic fibrosis. The child may be required to sleep regularly in a plastic mist tent, into which a dense fog is pumped to help liquefy mucus and check infection. Aerosol therapy is generally prescribed. Extracts of animal pancreas taken with meals, which should be high in protein and low in fat, compensate for pancreatic deficiency. Physical therapy involving postural drainage together with “clapping” and “vibrating” aids in loosening the mucus so that it can be coughed up and expectorated.

It is estimated that in the United States cystic fibrosis occurs once in every few thousand births. Caucasians appear more subject to it than blacks, and among those of Asian descent it seems to be rare.
Patient Care. Maintenance of the child's nutritional status may be difficult because of his tendency to cough and vomit frequently during feedings, and also because of difficulty in breathing. Small amounts of food, given slowly and at frequent intervals, are best for infants as well as for small children with cystic fibrosis.

Skin care is important, especially for infants and toddlers who are not yet toilet trained. The stools are likely to be copious and extremely irritating to the skin. Frequent turning of the infant or bedridden child helps to prevent decubitus ulcers and lessens the danger of pneumonia, a constant threat to these children. Prevention of infection is a most important aspect of the care of these children because of their extreme vulnerability to disorders of the respiratory tract.

Education of the parents must include the dietary regimen; how to use the Croupette, a machine for aerosol therapy in the home; hygienic measures to prevent infections; and the importance of continuous medical follow-up and administration of medications prescribed for the child.

cystic calculus
calculus in the urinary bladder.
cystic corpus luteum
the normal corpus luteum is solid. Some have a central cavity filled with fluid but this does not affect their function. See also luteal cyst.
cystic duct
the excretory duct of the gallbladder. See also bile duct.
cystic endometritis
cystic eye
the failure of the optic vesicle to come into close apposition to the cranial ectoderm during embryological development results in persistence of the vesicle and the formation of a cystic eye.
cystic follicle
see cystic follicle; cystic ovarian degeneration (below).
cystic hyperplasia
see cystic endometrial hyperplasia.
cystic hyperplasia-pyometra complex
the term applied to a series of endometrial changes leading to pyometra in dogs; first cystic endometrial hyperplasia, then plasma cell infiltration of the endometrium during diestrus, followed by acute inflammatory reaction which then becomes chronic.
cystic ovarian degeneration (disease)
includes cystic follicle, luteal cyst, cystic corpus luteum (above). A major cause of reproductive failure and economic loss in dairy cattle. Results in an increase in days open in the post partum period and an increase in culling rates for reproductive failure. It occurs when a mature follicle fails to ovulate as a result of exogenous or endogenous disruption of the hypothalamo-hypophyseal-ovarian axis; the resultant anovulatory follicular structure can regress or persist as a follicular cyst or a luteal cyst depending on its structural characteristics. Diagnosis and differentiation of follicular cysts and luteal cysts has traditionally been by rectal palpation but ultrasound examination is more accurate.
cystic pancreatic duct
a sometime congenital defect; occasionally associated with polycystic kidneys and cystic bile ducts.
cystic placental mole
results from the death of the fetus with the persistence of the fetal membranes.
cystic prostatic hyperplasia
caused by blockage of glandular ducts. Enlargement of the gland may cause constipation, possibly dysuria. The enlarged gland should be palpable per rectum.
cystic rete tubules
occur in the ovaries of cows, bitches, queens; may be sufficiently large to be mistaken for cystic follicles.
cystic retinal degeneration
cystic right oviduct
the right oviduct in birds regresses to a vestigial level in the adult; sometimes the regression is incomplete and a cyst develops.

Patient discussion about cystic

Q. Can cystic fibrosis patients have children? My boyfriend has cystic fibrosis, and currently he’s treated with many medications but usually healthy (other than pneumonia from hospitalization from time to time). I heard that men with cystic fibrosis can’t have children - is that true? Is there anything he can do about it?

A. WE ARE A HEALTHY COUPLE BUT MY WIFE NEVER GET PREGNANT IN 20 YEARS OF RELATIONSHIP.
I'M SO SORRY ABOUT MY ENGLISH, I'M LEARNING.

Q. Do women with cystic fibrosis have difficult pregnancy? My wife has cystic fibrosis, and after 3 year of marriage we decided we want a baby. I know that men with cystic fibrosis are usually infertile and can’t have children- is that the case also for women with cystic fibrosis? Is the pregnancy in women with cystic fibrosis more problematic? Is it dangerous?

A. Before you attempt a pregnancy, you should consult her doctor to make sure she can tolerate it, because very severe disease can make the pregnancy dangerous for her. If her disease isn’t so severe, usually there are no special problems.

Q. My daughter has a cystic mygroma. Has anyone else had this or know anyone who has, and how did you treat it? I really need some help on this issue, she has it in her neck and they say they shouldn't opperate because it may come back. I hope that someone out here can help me.

A. cystic hygroma is a benign lesion. therefore if surgery is not an option (the lesion is placed in a risky to operate area) they tend not to do so.. they use Sclerosing agents as Terrany suggested. include OK-432 , bleomycin, pure ethanol, bleomycin, sodium tetradecyl sulfate, and doxycycline.
ask your Doctors about them.
