GASTROESOPHAGEAL REFLUX AND SINUSITIS IN ASTHMA

TEMPS-A Temperament Scale Before and After Septoplasty in Patients with Nasal Septum Deviation

The present study aimed to evaluate whether patients undergoing an operation for septum deviation exhibited a change in affective status. The temperament evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) was administered to all patients at the pre-operative and post-operative periods. The mean age of the patients was 32.46 ± 11.22 years. Of the patients, 34 (65.4%) were males and 18 (34.6%) were females. A significant difference was found between pre- and post-operative scores of the patients on all TEMPS-A subscales (p < 0.05). Patients with symptoms of upper airway obstruction may have mood disorders due to the decrease in blood oxygen levels. This condition can be corrected with septoplasty procedure. In the present study, it was demonstrated that patients had a better affective status post-operatively as compared to the pre-operative period.

Nasopharyngeal pH Monitoring in Chronic Sinusitis Patients Using a Novel Four Channel Probe

OBJECTIVE

To determine the prevalence of acid reflux into the nasopharynx in patients with chronic sinusitis.

STUDY DESIGN

Prospective study of patients presenting to a specialist rhinology practice with chronic sinusitis.

METHODS

Forty patients with chronic sinusitis underwent ambulatory 24 hour pH testing. The mean age of the patients was 56.3 years (25 Female, 15 Male). The studies were performed using a specially developed bifurcated 4 channel pH probe, incorporating 2 circumferential sensors positioned at the naso- and hypo-pharynx, and 2 unidirectional sensors positioned at the proximal and distal esophagus.

RESULTS

The circumferential band sensors yielded a stable recording largely free of artefact allowing meaningful recordings to be obtained from thirty-seven patients. Twelve patients (32.4%) were diagnosed with gastroesophageal reflux. A total of 809 reflux episodes were recorded. Of these, 596 (73.7%) reached the distal esophagus, with 187 (23.1%) and 24 (3.0%) reaching the proximal esophagus and hypopharynx respectively. Only 2 episodes (0.2%) were recorded in the nasopharynx. This occurred in 2 of 37 patients (5%).

CONCLUSIONS

Acid reflux into the nasopharynx is a rare event in patients with chronic sinusitis even though a significant proportion (32.4%) have abnormal 24 hour pH studies. It is likely that alternative mechanisms other than direct acid contact are involved in the pathogenesis of chronic sinusitis.

Physical and pH properties of gastroesophagopharyngeal refluxate: a 24-hour simultaneous ambulatory impedance and pH monitoring study

OBJECTIVES

Frequency occurrence of nonacidic and nonliquid reflux events in the pharynx has not been systematically studied. The aim of the present study was to characterize the physical (liquid, gas, and mixed gas/liquid) and pH properties of the gastroesophagopharyngeal refluxate.

METHODS

We performed a total of 31 24-h simultaneous ambulatory pharyngoesophageal impedance and pH recordings in 11 GERD patients, 10 patients with reflux-attributed laryngitis, and 10 healthy controls.

RESULTS

On average, the total number of reflux events (all kinds) in the pharynx was less than half of that in the proximal esophagus (18 +/- 4 vs 50 +/- 4, p < 0.01). Most of the pharyngeal reflux events were gas events and were observed in all three studied groups. Prevalence of these gas reflux events ranged between 0 and 74. The number of gas reflux events accompanied by a minor pH drop in laryngitis patients (1 (0-36)) was significantly higher than those in GERD and controls (0 (0-2) and 0 (0-1), respectively, p < 0.05). There was no significant difference in the number of nonacidic gas reflux events among the three groups (GERD: 10 (2-57), laryngitis: 11.5 (0-51), controls: 10.5 (0-27)). Impedance recording identified a total number of 566 events in the pharynx. Of these, a total of 563 events were compatible with gas reflux events, 101 events were accompanied by minor drops in intrapharyngeal pH, whereas 460 events were not accompanied by any pharyngeal pH change.

CONCLUSIONS

Concurrent impedance and pH recordings detect significantly more events qualifying as reflux in the pharynx than pH recordings alone. A substantial majority of these events are gaseous refluxes both with and without minor pH drops. Gas reflux events with weak acidity appear to be more common among patients with reflux-attributed laryngeal lesions compared to GERD patients and controls.

Causative and contributive factors to asthma severity and patterns of medication use in patients seeking specialized asthma care

STUDY OBJECTIVES

(1) To assess the prevalence of specific factors considered causative or contributive to asthma in a population of patients seen in a specialized asthma clinic, and to determine whether any of these factors were associated with more severe disease; and (2) to assess the utilization of inhaled steroids by asthma severity in this population and compare it with published guidelines of the National Heart, Lung, and Blood Institute (NHLBI). DESIGN, SETTING, AND PATIENT POPULATION: We conducted a retrospective chart review of new patients seen in a specialized asthma treatment center over a 2.5-year period and recorded the prevalence of 14 causative or contributive factors, the severity of asthma, and the intensity of treatment with inhaled corticosteroids in each patient. Patients were grouped as mild asthma vs moderate/severe asthma and compared by chi(2) analysis and stepwise logistic regression to determine whether certain factors were associated with more severe asthma.

MEASUREMENTS AND RESULTS

The average number of factors recorded was 2.9 +/- 1.8 in the mild group (+/- SD) and 3.5 +/- 1.6 in the moderate/severe asthma group. This difference was statistically significant (p = 0.014). Increasing age, male gender, symptomatic gastroesophageal reflux disease (GERD), and chronic sinusitis were independently associated with more severe asthma. Suboptimal use of inhaled corticosteroids was more common in patients with mild persistent asthma, but suboptimal dosing of inhaled corticosteroids was equally common in mild and moderate/severe asthma. No relationship was found between allergen sensitization combined with exposure to cats, dogs, dust mite, or molds and more severe asthma.

CONCLUSIONS

This study confirms earlier studies showing that symptomatic GERD and chronic sinusitis are important comorbid conditions in patients with asthma, both being associated with greater asthma severity. This study further shows that the doses of inhaled corticosteroids used for treatment of asthma fall short of NHLBI guidelines in the majority of patients regardless of asthma severity.

The role of 24 h pH-recording in pediatric otolaryngologic gastro-esophageal reflux disease

The purpose of this study was to investigate the role of 24 h pH monitoring for the diagnosis of otolaryngologic including rhinologic manifestations of gastro-esophageal reflux (GER) in children and if possible to correlate the results with the efficacy of medical treatment. This is a retrospective study of 72 children from January 1997 to December 1999. The children were separated into three groups according to the main symptoms (although association of symptoms was frequent): rhinologic (n=28), laryngotracheal (n=28) and pharyngeal-otologic (n=16). With the classical gastroenterologic criterion (> or =4.2% of total time at pH < 4), the pH monitoring was positive in 56% of the patients. However, this criterion does not seem to be sensitive for otolaryngologic gastro-esophageal reflux disease (GERD) because multiple daytime short reflux episodes are often involved. Indeed, the pH monitoring was positive in 75% of the patients (82% in the rhinologic group) when a number of 40 episodes in 24h was also taken into account. The success rate of medical treatment was about 80% in case of positive pH recording. This study underlines that GER is an important factor in pediatric otolaryngologic diseases.

Infectious triggers of pediatric asthma

Respiratory infections can cause wheezing illnesses in children of all ages and also can influence the causation and disease activity of asthma. For years it has been recognized that respiratory syncytial virus infections often produce the first episode of wheezing in children who go on to develop chronic asthma. More recently, it has been proposed that repeated infections with other common childhood viral pathogens might help the immune system develop in such a way as to prevent the onset of allergic diseases and possibly asthma. In addition to the effects of viral infections, infections with certain intracellular pathogens, such as chlamydia and mycoplasma, may cause acute and chronic wheezing in some individuals, whereas common cold and acute sinus infections can trigger acute symptoms of asthma. In this article, the epidemiologic, mechanistic, and treatment implications of the association between respiratory infections and asthma are discussed.

Role of laryngoscopy, dual pH probe monitoring, and laryngeal mucosal biopsy in the diagnosis of pharyngoesophageal reflux

There is no standard for determining significant pharyngoesophageal reflux. This prospective blind comparison study compared dual pH probe studies, direct laryngoscopy, and mucosal biopsy in children without symptoms of gastroesophageal reflux who underwent airway evaluation. Significant reflux to the lower esophageal probe did not correlate with statistical significance with reflux to the upper probe. In this group of asymptomatic patients, a positive lower pH probe finding did not correlate with upper or lower esophageal mucosal inflammation. Eosinophilia in the esophageal mucosa is diagnostic of gastroesophageal reflux disease, and was seen in 5 of the laryngeal biopsies. A weak correlation was seen between positive findings at laryngoscopy and positive posterior cricoid biopsy in this group. There may be no consistent way to predict significant pharyngoesophageal reflux in asymptomatic patients. Single-probe pH testing will not predict significant pharyngoesophageal reflux with mucosal changes. Laryngoscopy and upper pH probe findings only weakly correlate with significant histologic findings. Laryngeal and posterior cricoid biopsy may be the only sensitive test for mucosal injury. Clinical trials of empiric antireflux therapy should be used to determine whether the laryngeal changes seen in these patients are reversible.

Sinusitis and its relationship to asthma. Can treating one airway disease ameliorate another?

In a large percentage of patients with upper airway disease, asthma and sinusitis occur concomitantly. As many as 88% of patients with asthma exhibit the symptoms of rhinitis, and half of rhinitic patients have asthma. In this article, Dr Muller explores the interrelationship of sinusitis and asthma, including characteristics, mechanisms of action, and diagnosis, and provides suggestions for optimal treatment of both.
