             minimum of 2 positive samples for P. aeruginosa over the previous 12 months and/or
             presence of more than two precipitating antibodies against P. aeruginosa;

          -  Sputum containing P. aeruginosa susceptible to tobramycin (defined as a zone diameter
             ≥ 16 mm after testing with 10 µg tobramycin disk or as a minimal inhibition
             concentration based on microdilution testing system) as identified by local laboratory
             at screening visit;

             weeks;

          -  Evidence of impaired renal function (serum creatinine level ≥ 1.5 mg/dl);

          -  Evidence of impaired auditory function (auditory threshold in either ear above 20 dB
             at frequencies between 250 and 8000Hz);

          -  Sputum culture containing Burkholderia cepacia;

          -  Patients with end-stage lung disease, candidates for heart-lung transplantation;

          -  History of other clinically significant cardiac, renal, neurological,
             gastrointestinal, hepatic or endocrine disease related to cystic fibrosis, whose
             sequelae and/or treatment can interfere with the results of the present study;

          -  Female subjects: pregnant or with active desire to be pregnant, lactating mother or
             lack of efficient contraception in a subject with child-bearing potential (i.e.,
             contraceptive methods other than rod containing a hormone that prevents user from
             getting pregnant and that will be placed under the skin, syringes that contain a
             contraceptive hormone, combined birth control pill, i.e., such that contains two
             hormones, some intrauterine devices (IUDs) and sexual abstinence). A pregnancy test in
             urine is to be carried out in women of a fertile age at screening and at the last
             clinic visit;

          -  Known hypersensitivity to aminoglycosides;

          -  Patients with evidence of alcohol or drug abuse, likely to be not compliant with the
             study protocol or likely to be not compliant with the study treatments;

          -  Participation in another clinical trial with an investigational drug in the four weeks
             preceding the screening visit.
No condition on gender to be admitted to the trial.
No healthy subjects accepted to join the trial.
Subject must be at least 6 Years old.


Patient description (medical language): A 30-year-old man who is a computer scientist came to the clinic with the lab result stating azoospermia.  The patient is sexually active with his wife and does not use any contraception methods.  They have been trying to conceive for the past year with no success.  The patient has a past medical history of recurrent pneumonia, shortness of breath, and  persistent cough that produces large amounts of thick sputum. The patient had multiple lung infections during childhood. He does not smoke, use illicit drugs or alcohol.  The patient has no history of other medical conditions including allergies or any kind of surgery.  On physical examination, the digits show clubbing.  An ultrasound shows bilateral absence of the vas deferens, and FEV1 was 75% on the respiratory function test.

Patient description (patient's own words): I'm a 30-year-old computer scientist. I did some lab tests that came back quite alarming, stating that I have azoospermia?! I'm sexually active with my wife and we don't use contraception. We've been trying to have a child for the past year. I have a medical history of pneumonia and shortness of breath and regular wet cough. I had several lung infections when I was a kid. That's why I'm very careful and don't smoke, do drugs, or drink. I don't have other medical conditions including allergies or any kind of surgery. The doctor did the clubbing test on my fingers, which was positive. I also did an ultrasound and it showed that I'm missing the tubes that carry sperm around. I also had a 75% for my respiratory function test.

Does the patient match the trial criteria? Entailment
