A comparison of salmeterol with albuterol in the treatment of mild-to-moderate asthma.

BACKGROUND: An effective, long-acting bronchodilator could benefit patients with asthma who have symptoms not controlled by antiinflammatory drugs. We compared a new long-acting, inhaled beta 2-adrenoceptor agonist, salmeterol, with a short-acting beta 2-agonist, albuterol, in the treatment of mild-to-moderate asthma. METHODS: We randomly assigned 234 patients (150 male and 84 female patients 12 to 73 years old) to one of three treatment groups: one group received 42 micrograms of salmeterol twice daily, one received 180 micrograms of albuterol four times daily, and one received placebo. Treatment was assigned in a double-blind fashion, and all patients could use supplemental inhaled albuterol as needed during the 12-week treatment period. RESULTS: Measurements of the forced expiratory volume in one second, performed hourly for 12 consecutive hours, showed that a single dose of salmeterol produced a greater mean area under the curve than two doses of albuterol taken 6 hours apart (6.3 vs. 4.9 liter.hr, P < 0.05). The difference was significant on day 1 and at week 4 of the study, but not at week 8 or 12. Salmeterol was also more effective than albuterol or placebo (with albuterol taken as needed) in increasing the morning peak expiratory flow rate: salmeterol induced a mean increase of 24 liters per minute over the pretreatment values, as compared with a decrease of 6 liters per minute with albuterol (P < 0.001) and an increase of 1 liter per minute with placebo (P = 0.002). The mean overall symptom score was improved most by salmeterol treatment (P < 0.05), with the number of days with symptoms and of nights with awakenings decreasing by 22 percent and 52 percent, respectively; there were no differences in results between albuterol treatment and placebo administration. We found no evidence of tolerance to the bronchodilating effects of salmeterol, and adverse reactions to all the treatments were infrequent and mild. CONCLUSIONS: For the management of mild-to-moderate asthma, salmeterol given twice daily is superior to albuterol given either four times daily or as needed.

Ipratropium bromide aqueous nasal spray for patients with perennial allergic rhinitis: a study of its effect on their symptoms, quality of life, and nasal cytology.

Ipratropium bromide is an anticholinergic agent with topical activity that has been studied as a freon-propelled aerosol spray for therapy of nonallergic rhinitis. This is the first report of its use both as an aqueous nasal spray and in perennial allergic rhinitis. In this study 123 patients who had symptoms of perennial allergic rhinitis were randomized to receive ipratropium bromide 21 micrograms or 42 micrograms or placebo, one spray per nostril three times a day for 4 weeks. Patients maintained daily diaries of duration and severity of nasal symptoms and were evaluated weekly. Mean duration and severity of rhinorrhea was decreased in both ipratropium bromide treatment groups by comparison with placebo, with consistently greatest improvement in the group treated with ipratropium bromide 42 micrograms per nostril three times a day. No statistically significant differences occurred among treatment groups in duration or severity of postnasal drip, congestion, or sneezing. Seventy percent of patients treated with 42 micrograms of ipratropium bromide thought it had good or excellent effect on rhinorrhea (p less than 0.05 vs placebo); significantly more patients thought that it had improved the quality of life (p = 0.02). No changes occurred in nasal cytology, and no significant local or systemic adverse events occurred. These data indicate that ipratropium bromide significantly decreases the rhinorrhea of perennial allergic rhinitis.

A double-blind, placebo-controlled study of the safety and efficacy of ipratropium bromide nasal spray versus placebo in patients with the common cold.

Ipratropium bromide (IB) has been found to reduce secretions in the upper respiratory tract; this is accomplished through competitive inhibition of acetylcholine at muscarinic receptors that control rhinorrhea production. This study compared the safety and efficacy of IB with placebo in the symptomatic relief of rhinorrhea in patients with the common cold. Human subjects with symptoms of a common cold, primarily rhinorrhea, were enrolled and treated with either IB (84 micrograms/nostril) or placebo; each was administered as two sprays per nostril, four times a day, for 4 days. Primary efficacy analyses were in-clinic measurements of nasal discharge weights over a 3-hour period after administration on days 1 and 2 and assessment of rhinorrhea symptoms by use of a subjective patient-completed visual analog rating scale. IB significantly reduced rhinorrhea an average of 18% over placebo for days 1 and 2 (p = 0.01). Visual analog scale scores showed an average improvement in rhinorrhea of 22% over placebo (p = 0.001). When patients with relatively minor rhinorrhea (baseline weight of nasal discharge < or = 1.0 gm) were excluded, IB produced an average reduction in nasal discharge of 23% over placebo for days 1 and 2 (p = 0.003).

General purpose medical imaging databases: three models.

A useful general purpose digital medical image database project can begin with relatively simple and low-cost capabilities provided by a computer operating system. As the amount of data and the number of users grow, transition to a relational database model becomes appropriate. When multiple database systems are present, a flexible front end can provide sophisticated querying capabilities that bridge the systems, while hiding the complexities of the multiple systems from the user.

Designing a critical care unit: description of a multidisciplinary process.

Overall we are pleased to find that what sometimes seemed like hopeless space restrictions could be overcome by a combination of prudent compromise and innovative design. Even though the process consumed much time, the design of this new ICU turned out to be a satisfying process, marked by a true cooperative spirit among a group with diverse backgrounds and skills, all working toward a common goal.

Local food and nutrition policy.

Local food and nutrition policies (small-scale efforts to create food systems that respond to nutritional needs) are becoming more and more fashionable as a way of improving public health in Australia. Opportunities for local food and nutrition policies include urban planning, institutional catering, the private sector and local government. These policies are only feasible in organisational environments that are ready to receive them, although their chances of improving the population's food supply can be maximised by copying some aspects of successful policy programs of the past.

A prevention model for occupational therapy.

The role of occupational therapy in prevention has received much discussion but relatively little empirical testing and model building. Because of the evidence linking stress and illness, the life stress process has become a popular area of investigation. More importantly, a role strain model can provide a theoretical guide to occupational therapy practice due to the central importance of adaptive behavior and social competence. To illustrate, the maternal stress study is presented as an example of prevention research that examines the relationship between maternal stress and child psychopathology. Risk factors are identified as the first step in reliable case finding and the design of preventive interventions. Such model building can help occupational therapists develop prevention services for vulnerable populations.

Dose tolerance study of fluticasone propionate aqueous nasal spray in patients with seasonal allergic rhinitis.

A multicenter, double-blind, parallel-group, dose-tolerance study was conducted to evaluate the safety of fluticasone propionate aqueous nasal spray, a potent new corticosteroid preparation. Ninety-seven adult patients with moderate to severe seasonal allergic rhinitis during the fall weed season received either placebo or fluticasone propionate in doses of 50, 200, or 800 micrograms twice daily for 4 weeks. Safety evaluations included adrenal function evaluation by morning plasma cortisol concentration, response to ACTH stimulation, and 24-hour urinary free cortisol excretion. There was no evidence of effects on adrenal function at any dose. The severity, nature, and frequency of adverse events were similar across all treatment groups, including placebo. Drug-related adverse events were consistent with local nasal irritation. The groups receiving fluticasone propionate showed greater improvement in nasal symptoms (obstruction, rhinorrhea, sneezing, and itching) than did the placebo group. The results demonstrate that fluticasone propionate aqueous nasal spray is safe in doses up to 1600 micrograms per day and effective in the treatment of seasonal allergic rhinitis.

Once daily fluticasone propionate aqueous nasal spray is an effective treatment for seasonal allergic rhinitis.

A multicenter double-blind, randomized, parallel group study was conducted to evaluate the once daily administration of fluticasone propionate, a potent, new corticosteroid preparation, for the treatment of seasonal allergic rhinitis. Adult patients (n = 227) were treated for 2 weeks with fluticasone propionate aqueous nasal spray 200 micrograms QD or 100 micrograms BID or matching placebo during the autumn pollen season. Overall, the administration of fluticasone propionate once daily in the morning was as effective as the twice daily dosage regimen, and either regimen was more effective than placebo. Improvement in clinician-rated and patient-rated nasal symptom scores, including morning nasal obstruction, was evident within three days of fluticasone propionate therapy and continued throughout the treatment period. Fewer patients receiving fluticasone propionate used rescue medication and had nasal eosinophilia compared with patients receiving placebo. Adverse events were similar in frequency and nature in all three treatment groups. Morning plasma cortisol concentrations and response to cosyntropin stimulation were similar across groups and offered no evidence of HPA axis suppression. We conclude that fluticasone propionate aqueous nasal spray administered once daily is a safe and effective treatment for seasonal allergic rhinitis. The convenience of a once daily regimen may encourage better compliance.

Clinical evaluation of triamcinolone acetonide nasal aerosol in children with perennial allergic rhinitis.

Triamcinolone acetonide aerosol (TAA), a topical corticosteroid, now available for intranasal use, has been shown to be highly effective in the treatment of both seasonal and perennial allergic rhinitis (PAR) in adults. To evaluate the efficacy and safety of TAA in children, 210 patients (ages 4 to 12 years) with PAR were randomly assigned to one of three treatment groups (placebo, TAA 82.5 micrograms/day, or TAA 165 micrograms/day). Medication was given tid over 12 weeks in a double-blind fashion. Response to medication was evaluated using symptom scoring, physician evaluation, and, in 44 patients, nasal airflow determinations by anterior rhinomanometry. The higher dose of TAA (165 micrograms/day) significantly improved rhinitis symptoms relative to placebo: the total nasal symptom score and most individual symptom scores (eg, nasal stuffiness, itch, sneezing) were significantly better, duration of rhinitis symptoms (hours per day) was significantly reduced, and nasal airflow in a subset of patients showed significant improvement. The lower dose of TAA (82.5 micrograms/day) was superior to placebo by the same parameters as the higher dose, but this improvement was not as consistently significant as the higher dose. There were no clinically significant adverse events; nasal irritation and epistaxis were rare with a similar incidence among treatment groups. In conclusion, TAA at 165 micrograms/day was effective in controlling the symptoms of PAR and in improving nasal airflow in pediatric patients; the lower dose (82.5 micrograms/day) was marginally effective. Both doses were safe and well-tolerated in the children studied.

Improved stability in oral delivery of albuterol provides less variability in bronchodilation in adults with asthma.

The objective of this randomized, single-blind, parallel group study was to determine whether a more constant rate of albuterol delivery from tablets provides less variability in bronchodilation. Thirty-eight adult patients were enrolled with FEV1 between 40% to 80% of predicted normal and greater than or equal to 15% reversibility. Eighteen patients received Volmax, 8 mg bid, and 20 patients received Proventil Repetabs, 8 mg (as two 4-mg tablets) bid. The magnitude and duration of bronchodilation were determined after the first dose and at steady state on treatment day 7 by measuring serial values of pulmonary function for 12 hours on each day. Interpatient variability in bronchodilation was calculated for each study day did not differ significantly between treatments, the interpatient variability in bronchodilation with Volmax was, on average, one-half of that experienced with Proventil Repetabs. Adverse events, mainly headache and tremor, were comparable between Volmax and Proventil Repetabs. This study demonstrates that Volmax achieves less variable bronchodilation through a more constant rate of drug delivery from the onset of therapy.

A dose-ranging study of fluticasone propionate aqueous nasal spray for seasonal allergic rhinitis assessed by symptoms, rhinomanometry, and nasal cytology.

Fluticasone propionate is a new glucocorticosteroid with potent topical activity. In a double-blind, randomized, parallel-group study, 423 adult patients with moderate to severe seasonal allergic rhinitis received placebo or fluticasone propionate aqueous nasal spray at doses of 25, 100, or 400 micrograms twice daily (b.i.d.) for 2 weeks. Efficacy was evaluated by nasal symptom scores, nasal airflow, nasal cytology, and global evaluation. All doses of fluticasone propionate were significantly better than placebo in reducing symptoms of seasonal allergic rhinitis. Patients receiving the largest dose of fluticasone propionate (400 micrograms b.i.d.) had a slightly greater reduction (not significant) in symptom scores than patients receiving the smallest dose (25 micrograms b.i.d.). Symptom improvement was evident within 3 days of treatment. Nasal airflow improved in the groups treated with fluticasone propionate, 100 and 400 micrograms b.i.d. Examination of nasal cytograms revealed a striking decrease in both eosinophils and basophils in all three groups receiving active treatment compared with placebo. There were few adverse events and no treatment-related abnormalities in laboratory assays or evaluations of hypothalamo-pituitary-adrenocortical axis function. Comparison of treatment groups indicated that fluticasone propionate aqueous nasal spray was as safe as placebo at the doses studied.
