Sweat sodium levels in adults with nasal polyps.

Nasal polyps occur in 10% of children and 48% of adults with cystic fibrosis. The prevalence of abnormal sweat tests and cystic fibrosis in adults with nasal polyps has not been reported. We therefore performed sweat tests on 35 adults with nasal polyposis seen in two allergists' office practice.

Effect of sibship position on reproductive behavior of couples after the birth of a genetically handicapped child.

We compared the reproductive behavior of 132 white married couples of whom 44 had a child with cystic fibrosis, 44 with either Down Syndrome or neural tube defect, and 44 with cerebral palsy to that of the general USA white married population. The three groups of couples were similar respecting race, religion, maternal age, parental occupation and education, and sex of affected child. Most couples had received some genetic counseling and all were followed for at least 3 years after diagnosis of the affected child.

Bacteriology of the maxillary sinuses in patients with cystic fibrosis.

The maxillary sinuses of 20 patients (median age, 15 years) with cystic fibrosis were examined with ultrasound, radiography, and transantral sinus aspiration (14 bilateral and six unilateral for a total of 34 aspirates). The sinus aspirations were performed with careful sterile techniques, and the material that was recovered was cultured quantitatively for both aerobic and anaerobic bacteria. Nineteen (95%) of the 20 patients had at least one positive (greater than or equal to 10(4) colony-forming units/ml) culture of sinus aspirate.
