Comparison of a beta-lactam alone versus beta-lactam and an aminoglycoside for pulmonary exacerbation in cystic fibrosis.

Unlabelled: We determined whether a beta-lactam and an aminoglycoside have efficacy greater than a beta-lactam alone in the management of a pulmonary exacerbation in patients with cystic fibrosis.

Study Design: Azlocillin and placebo or azlocillin and tobramycin were administered to 76 patients with a pulmonary exacerbation caused by Pseudomonas aeruginosa in a randomized double-blind, third-party monitored protocol. Improvement was assessed by standardized clinical evaluation, pulmonary function testing, sputum bacterial density, sputum DNA content, and time to the next pulmonary exacerbation requiring hospitalization.

Timing of referral for lung transplantation for cystic fibrosis: overemphasis on FEV1 may adversely affect overall survival.

Study Objectives: (1) Report our experience with referral for lung transplantation. (2) Review survival in cvstic fibrosis (CF) patients without lung transplantation after FEV1 remains < 30% predicted for 1 years.

Design: Retrospective review.

Stenotrophomonas maltophilia in cystic fibrosis: incidence and prevalence.

Stenotrophomonas maltophilia (SM) was recovered from 211 of 773 cystic fibrosis (CF) patients followed for at least one year, and seen between 1982 and 1994. Yearly prevalence (5.6% to 8.

Sodium space and intravascular volume: dietary sodium effects in cystic fibrosis and healthy adolescent subjects.

Objective: To assess the physiologic response to salt depletion in subjects with cystic fibrosis (CF) and control male adolescents for sodium balance, sodium space, and stimulation of the renin-angiotensin-aldosterone axis.

Design: Seven subjects with CF and six controls received a salt-replete (150 or 290 mmol NaCl per day) diet and then a salt-deplete (10 mmol NaCl per day) diet while in a clinical research center.

Results: Space maintenance: CF subjects responded to salt depletion with a greater weight loss than did controls (1.

Pulmonary intralobar sequestration in a patient with cystic fibrosis.

We report a case in which pulmonary Intralobar Sequestration (ILS) was an incidental finding at autopsy in an adult with Cystic Fibrosis. Two aberrant arteries from the descending thoracic aorta supplied a bronchial cystic lesion in the right lower lobe. Termination of the segmental bronchus and scar formation proximal to the cyst suggested prior bronchial obliteration.

Nontuberculous mycobacteria in cystic fibrosis. An autopsy study.

We retrospectively studied lung and hilar lymph nodes at autopsy in 18 patients with cystic fibrosis (CF) who had antemortem sputum cultures positive for nontuberculous mycobacteria (NTM). Histologic features were compared with those of 18 patients with CF who had negative antemortem cultures. The most frequent species isolated was M.

Urolithiasis and cystic fibrosis.

Purpose: We determined whether cystic fibrosis patients are at increased risk for the development of urolithiasis.

Materials And Methods: Telephone interviews were conducted with 201 cystic fibrosis patients older than 15 years to identify those with a history of urolithiasis. Histories were confirmed by chart review, and only patients with urolithiasis documented by excretory urography, renal ultrasound or spontaneous passage of a stone were included.

3849+10 kb C-->T mutation and disease severity in cystic fibrosis.

50% of patients with cystic fibrosis (CF) are homozygous for the delta F508 mutation, but the remainder have at least one of many other less common mutations. The 3849 + 10 kb C-->T splice mutation seems to be associated with less severe disease. We report ten CF patients who are hemizygous for this mutation.

Maternal child-rearing behavior in three groups: cystic fibrosis, insulin-dependent diabetes mellitus, and healthy children.

Compared child-rearing behaviors among mothers of children (ages 4-14) with cystic fibrosis (CF) (N = 26), insulin-dependent diabetes mellitus (IDDM) (N = 26), and mothers of physically healthy children (N = 26), on six domains, including involvement, limit setting, responsiveness, reasoning and guidance, free expression, and intimacy using the Iowa Parent Behavior Inventory. Maternal Reports of their child-rearing behavior were comparable across the three groups with one exception: Mothers of children with chronic illnesses (CF and IDDM) were significantly less likely to set limits than mothers of healthy children. The present findings are consistent with those of other studies that have identified few differences in child-rearing practices between mothers of children with chronic illnesses and mothers of healthy children.

An expanded scoring system including an index of nutritional status for patients with cystic fibrosis.

Evaluation of success or failure of therapy for patients with cystic fibrosis (CF) commonly relies on the results of a single pulmonary function test (PFT). Most PFT measurements reflect different functional aspects of the lung. Although no single parameter can summarize all aspects of lung function, a combination of several may provide an advantage by reflecting the overall abnormality of lung function in one number.

Spontaneous bacterial peritonitis in cystic fibrosis.

Bacterial peritonitis presents with classic symptoms of fever and abdominal pain. Some patients, however, are completely asymptomatic. Death in the short term is considerable, especially in patients with alcoholic cirrhosis.

Erosion of the wall of the frontal sinus caused by mucopyocele in cystic fibrosis.

Three patients with cystic fibrosis had complete erosion of one of the walls of a frontal sinus caused by a mucopyocele. Only fibrous tissue then separated the purulent contents of the sinus from the orbit or central nervous system. Initial surgery was unsuccessful, but two patients have remained free of symptoms after a second obliterating procedure.

Efficacy of the Flutter device for airway mucus clearance in patients with cystic fibrosis.

The Flutter is a handheld device designed to facilitate clearance of mucus in hypersecretory lung disorders. Exhalation through the Flutter results in oscillations of expiratory pressure and airflow, which vibrate the airway walls (loosening mucus), decrease the collapsibility of the airways, and accelerate airflow, facilitating movement of mucus up the airways. We studied 18 patients with cystic fibrosis and mild to moderate lung disease to determine the efficacy of the Flutter in clearing mucus from the airways.

Long-term parenteral nutrition in cystic fibrosis.

The effects of parenteral nutrition (PN) with high lipid content were studied in 18 cystic fibrosis patients in this pilot investigation. The patients were randomly assigned to one of two groups. During the first 4-mo period, group 1 received PN and group 2 received routine therapy.

The prognostic value of exercise testing in patients with cystic fibrosis.

Background: Previous studies have shown female sex, impaired pulmonary function, older age, malnutrition, and colonization of the respiratory tract with Pseudomonas cepacia to be associated with a poor prognosis in patients with cystic fibrosis. We sought to determine the prognostic value of exercise testing in addition to the other prognostic factors.

Methods: A total of 109 patients with cystic fibrosis, 7 to 35 years old, underwent pulmonary-function and exercise testing in the late 1970s.

The nasal response to exercise in patients with cystic fibrosis.

This study has evaluated the nasal response to exercise in patients with cystic fibrosis (CF), a genetic disease in which factors such as chronic lung disease and/or nasal polyposis might be anticipated to modify nasal function responses. Measurements of nasal resistance (NAR) by posterior rhinomanometry and specific airway resistance (sRAW) were made before and 1, 5, 10, and 30 min after a 4-min period of exhausting legwork exercise (50% predicted maximal) in 19 CF patients (aged 11-29 years) and 10 healthy subjects (aged 11-31 years). One minute after exercise, healthy subjects showed a 54 +/- 5% (mean +/- SEM; standard error of the mean) relative fall from baseline in NAR and CF patients showed a 31 +/- 8% relative fall from baseline (p < 0.

Use of nonmedical treatment by cystic fibrosis patients.

To determine frequency, perceived effectiveness, and cost of religious, physical, and other nonmedical practices, we interviewed all (n = 402; 100% participation) of our cystic fibrosis patients/families [age, 0-45 (median, 18) years]. At least one type of nonmedical therapy was used by/on 264 (66%), two-thirds of which was religious. Most respondents perceived benefit (e.

Medical and social factors as predictors of outcome in infant tracheostomy.

We examined the relative impact of infant tracheostomy in comparison to associated medical and social factors, on developmental outcome as part of a cross-sectional follow-up of 32 children. These children had no mental retardation, physical handicap, or severe neurological problems, but had a history of long-term tracheostomy in infancy, ranging from 3 to 146 months duration. Medical factors evaluated included prematurity, neurological status, severity of illness, and number of weeks hospitalized.

The spectrum of appendiceal disease in cystic fibrosis.

A retrospective review of 1,220 cystic fibrosis (CF) patients between 1965 and 1989 identified 60 patients who underwent appendectomy. Ten had appendectomy prior to referral and 16 had an incidental appendectomy (primarily meconium ileus). Among the remaining 34 patients, acute appendicitis was present in 19 (1.

Bronchial artery embolization to control hemoptysis in cystic fibrosis.

Severe hemoptysis in cystic fibrosis can be life-threatening because of acute blood loss or because it interferes with sustaining physical therapy of the chest. Hemoptysis was controlled in 19 of 20 cystic fibrosis patients by means of embolization with a combination of 250-590-microns particles of polyvinyl alcohol foam and absorbable gelatin pledgets. Repeat embolization was needed in eight patients to achieve or maintain effective hemostasis.

Weight and menstrual function in patients with eating disorders and cystic fibrosis.

Many patients with eating disorders have menstrual dysfunction. In patients with anorexia nervosa, amenorrhea has been linked to weight loss. However, many patients with bulimia nervosa, even those of average or greater than average weight, also experience menstrual abnormalities, including amenorrhea.

Monocytes in cystic fibrosis: responsiveness to microbial stimuli.

Peripheral blood monocytes were obtained from 19 patients with cystic fibrosis (CF) and age-matched paired normal individuals. The oxidative metabolic response of these cells was measured by superoxide anion production before and after stimulation with Salmonella typhimurium or Pseudomonas aeruginosa lipopolysaccharide (LPS). CF monocytes showed slightly greater spontaneous superoxide anion production (14.

Developmental sequelae of long-term infant tracheostomy.

The records of 130 children who had had a tracheostomy for more than one month between 1972 and 1982 were reviewed for birth, medical and demographic characteristics, and 32 who were not severely physically or mentally handicapped were followed up at a mean age of 5.5 years. Rates of mortality and morbidity were high, and half of the survivors had moderate to severe intellectual and physical impairments.
