Is this true Cystic fibrosis is a viral disease?
No. Cystic fibrosis is a genetic disease.
Is it true or false that cystic fibrosis is a transmittable disease in the lungs?
Cystic Fibrosis is not contagouse because it is a genetic dissorder (you can only have it if you have the genes that give people CF)
True False Cystic fibrosis is caused by a mutation that is the dominant allele of a gene?
False.
Why does cystic fibrosis make people infertile?
Over 95% of males with cystic Fibrosis are infertile. There are 3 reasons why this is true. 1) Often, the males lacks the pretense of his vas deferens, the tubes which move sperm from the testicles to the penis. 2) At other times, the vas deferens is blocked, and sperm are unable to pass through. 3) Finally, when there is a sufficient opening for the sperm to pass through, the sperm are insufficiently mobile and cannot make their way through the vaginal tract to the female egg.
Is it true that if tissue damage is very severe tissue repair is more likely to occur by fibrosis or scarring?
fibrosis
Is the repair of cardiac muscle and nervous tissue done by fibrosis?
true
Cystic fibrosis?
DefinitionCystic fibrosis is an inherited disease that causes thick, sticky mucus to build up in the lungs and digestive tract. It is one of the most common chronic lung diseases in children and young adults, and may result in early death.See also:Cystic fibrosis - nutritional considerationsNeonatal cystic fibrosis screeningCauses, incidence, and risk factorsCystic fibrosis (CF) is caused by a defective gene which causes the body to produce abnormally thick and sticky fluid, called mucus. This mucus builds up in the breathing passages of the lungs and in the pancreas, the organ that helps to break down and absorb food.This collection of sticky mucus results in life-threatening lung infections and serious digestion problems. The disease may also affect the sweat glands and a man's reproductive system.Millions of Americans carry the defective CF gene, but do not have any symptoms. That's because a person with CF must inherit two defective CF genes -- one from each parent. An estimated 1 in 29 Caucasian Americans have the CF gene. The disease is the most common, deadly, inherited disorder affecting Caucasians in the United States. It's more common among those of Northern or Central European descent.Most children with CF are diagnosed by age 2. A small number, however, are not diagnosed until age 18 or older. These patients usually have a milder form of the disease.SymptomsBecause there are more than 1,000 mutations of the CF gene, symptoms differ from person to person.Symptoms in newborns may include:Delayed growthFailure to gain weight normally during childhoodNo bowel movements in first 24 to 48 hours of lifeSalty-tasting skinSymptoms related to bowel function may include:Belly pain from severe constipationIncreased gas, bloating, or a belly that appears swollen (distended)Nausea and loss of appetiteStools that are pale or clay colored, foul smelling, have mucus, or that floatWeight lossSymptoms related to the lungs and sinuses may include:Coughing or increased mucus in the sinuses or lungsFatigueNasal congestion caused by nasal polypsRecurrent episodes of pneumonia. Symptoms in someone with cystic fibrosis include: FeverIncreased coughingIncreased shortness of breathLoss of appetiteMore sputumSinus pain or pressure caused by infection or polypsSigns and testsA blood test is available to help detect CF. The test looks for variations in a gene known to cause the disease. Other tests use to diagnose CF include:Immunoreactive trypsinogen (IRT) test is a standard newborn screening test for CF. A high level of IRT suggests possible CF and requires further testing.Sweat chloride test is the standard diagnostic test for CF. A high salt level in the patient's sweat is a sign of the disease.Other tests that identify problems that can be related to cystic fibrosis include:Chest x-ray or CT scanFecal fat testLung function testsMeasurement of pancreatic functionSecretin stimulation testTrypsin and chymotrypsin in stoolUpper GI and small bowel seriesTreatmentAn early diagnosis of CF and a comprehensive treatment plan can improve both survival and quality of life. Follow-up and monitoring are very important. If possible, patients should be cared for at cycstic fibrosis specialty clinics, which can be found in many communities. When children reach adulthood, they should transfer to a cystic fibrosis specialty center for adults.Treatment for lung problems includes:Antibiotics to prevent and treat lung and sinus infections. They may be taken by mouth, or given in the veins or by breathing treatments. People with cystic fibrosis may take antibiotics only when needed, or all the time. Doses are usually higher than normal.Inhaled medicines to help open the airwaysDNAse enzyme replacement therapy to thin mucus and make it easier to cough upFlu vaccine and pneumococcal polysaccharide vaccine (PPV) yearly (ask your health care provider)Lung transplantis an option in some casesOxygen therapy may be needed as lung disease gets worseTreatment for bowel and nutritional problems (see: Cystic fibrosis - nutritional considerations) may include:A special diet high in protein and calories for older children and adults (see: Cystic fibrosis nutrional considerations)Pancreatic enzymes to help absorb fats and proteinVitamin supplements, especially vitamins A, D, E, and KYour doctor can suggest other treatments if you have very hard stoolsCare and monitoring at home should include:Avoiding smoke, dust, dirt, fumes, household chemicals, fireplace smoke, and mold or mildewClearing or bringing up mucus or secretions from the airways. This must be done one to fours times each day. Patients, families, and caregivers must learn about doing chest percussion and postural drainage to help keep the airways clearDrinking plenty of fluids. This is particularly true for infants, children, in hot weather, when there is diarrhea or loose stools, or during extra physical activityExercising two or three times each week. Swimming, jogging, and cycling are good options. Avoid contact sports, scuba diving, and endurance activities such as marathonsSupport GroupsFor additional information and resources, see: Cystic fibrosis support groupExpectations (prognosis)Most children with cystic fibrosis are fairly healthy until they reach adulthood. They are able to participate in most activities and should be able to attend school. Many young adults with cystic fibrosis finish college or find employment.Lung disease eventually worsens to the point where the person is disabled. Today, the average life span for people with CF who live to adulthood is approximately 35 years, a dramatic increase over the last three decades.Death is usually caused by lung complications.ComplicationsThe most common complication is chronic respiratory infection.Bowel problems, such as gallstones, intestinal obstruction, and rectal prolapseCoughing up bloodChronic respiratory failureDiabetesInfertilityLiver diseaseor liver failure, pancreatitis, biliary cirrhosisMalnutritionNasal polyps and sinusitisOsteoporosisand arthritisPneumonia, recurrentPneumothoraxRight-sided heart failure (cor pulmonale)Calling your health care providerCall your health care provider if an infant or child has symptoms of cystic fibrosis.Call your health care provider if a person with cystic fibrosis develops new symptoms or if symptoms get worse, particularly severe breathing difficulty or coughing up blood.Call your health care provider if you or your child experiences:Fever, increased coughing, changes in sputum or blood in sputum, loss of appetite, or other signs of pneumoniaIncreased weight lossMore frequent bowel movements or stools that are foul-smelling or have more mucusSwollen belly or increased bloatingPreventionThere is no way to prevent cystic fibrosis. Screening those with a family history of the disease may detect the cystic fibrosis gene in 60 - 90% of carriers, depending on the test used.ReferencesBoat TF, Acton JD. Cystic fibrosis.
