A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES.

Time course of respiratory decompensation in chronic obstructive pulmonary disease: a prospective, double-blind study of peak flow changes prior to emergency department visits. (1/1139)

The aim of this study was to look at changes in peak expiratory flow rates (PEFR) prior to emergency department visits for decompensated chronic obstructive pulmonary disease (COPD). It was designed as a prospective, double-blind study at the Albuquerque Veterans Affairs Medical Center. Twelve patients with an irreversible component of airflow obstruction on pulmonary function tests were assessed. At entry, all subjects were instructed in the use of a mini-Wright peak flow meter with electronic data storage. They then entered a 6-month monitoring phase in which they recorded PEFR twice daily, before and after bronchodilators. The meter displays were disabled so that the patients and their physicians were blinded to all values. Medical care was provided in the customary manner. Patients were considered to have respiratory decompensation if they required treatment for airflow obstruction in the Emergency Department (ED) and no other causes of dyspnea could be identified. Simple linear regression was used to model changes in PEFR over time. The 12 subjects had 22 episodes of respiratory decompensation during 1741 patient-days of observation. Two episodes could not be analysed because of missing values. Ten episodes in seven subjects were characterized by a significant linear decline in at least one peak flow parameter prior to presentation. The mean rates of change for the four daily parameters varied from 0.22% to 0.27% predicted per day (or 1.19 to 1.44 1 min-1 day-1). The average decrement in these parameters ranged from 30.0 to 33.8 1 min-1 (or 18.6%-25.9% of their baseline values). No temporal trends were found for the 10 episodes occurring in the other five subjects. We concluded that respiratory decompensation is characterized by a gradual decline in PEFR in about half of cases. Future studies should be done to elucidate the mechanisms of respiratory distress in the other cases.  (+info)

Randomised controlled trial of budesonide for the prevention of post-bronchiolitis wheezing. (2/1139)

BACKGROUND: Previous studies suggest that recurrent episodes of coughing and wheezing occur in up to 75% of infants after acute viral bronchiolitis. AIM: To assess the efficacy of budesonide given by means of a metered dose inhaler, spacer, and face mask in reducing the incidence of coughing and wheezing episodes up to 12 months after acute viral bronchiolitis. METHODS: Children under the age of 12 months admitted to hospital with acute viral bronchiolitis were randomised to receive either budesonide or placebo (200 microg or one puff twice daily) for the next eight weeks. Parents kept a diary card record of all episodes of coughing and wheezing over the next 12 months. RESULTS: Full follow up data were collected for 49 infants. There were no significant differences between the two study groups for the number of infants with symptom episodes up to six months after hospital discharge. At 12 months, 21 infants in the budesonide group had symptom episodes compared with 12 of 24 in the placebo group. The median number of symptom episodes was 2 (range, 0-13) in those who received budesonide and 1 (range, 0-11) in those who received placebo. Because there is no pharmacological explanation for these results, they are likely to be caused by a type 1 error, possibly exacerbated by there being more boys in the treatment group. CONCLUSION: Routine administration of budesonide by means of a metered dose inhaler, spacer, and face mask system immediately after acute viral bronchiolitis cannot be recommended.  (+info)

Persistent cough: is it asthma? (3/1139)

The aim of this study was to determine if children in the community with persistent cough can be considered to have asthma. A validated questionnaire was given to the parents of 1245 randomly selected children aged 6-12 years. Atopy was measured with skin prick tests. Children with persistent cough had less morbidity and less atopy compared with children with wheeze. Although the syndrome commonly referred to as "cough variant asthma" could not be shown in this study, a significant number of children with persistent cough had been diagnosed as having asthma and were treated with asthma medications including inhaled corticosteroids. Studies are urgently needed to determine the appropriate treatment for children with persistent cough.  (+info)

Repeatability of lung function tests during methacholine challenge in wheezy infants. (4/1139)

BACKGROUND: The repeatability of lung function tests and methacholine inhalation tests was evaluated in recurrently wheezy infants over a one month period using the rapid thoracic compression technique. METHODS: Eighty-one wheezy, symptom free infants had pairs of methacholine challenge tests performed one month apart. Maximal flow at functional residual capacity (VmaxFRC) and transcutaneous oxygen tension (Ptco2) were measured at baseline and after methacholine inhalation. Provocative doses of methacholine causing a 15% fall in Ptco2 (PD15 Ptco2) or a 30% fall in VmaxFRC (PD30 VmaxFRC) were determined. RESULTS: Large changes in VmaxFRC were measured from T1 to T2 with a mean difference between measurements (T2-T1) of 7 (113) ml/s and a 95% range for a single determination for VmaxFRC of 160 ml/s. The mean (SD) difference between pairs of PD30 VmaxFRC measurements was 0.33 (1.89) doubling doses with a 95% range for a single determination of 2.7 doubling doses. Repeatability of PD15Ptco2 was similar. A change of 3.7 doubling doses of methacholine measured on successive occasions represents a significant change. CONCLUSIONS: Baseline VmaxFRC values are highly variable in wheezy, symptom free infants. Using either VmaxFRC or Ptco2 as the outcome measure for methacholine challenges provided similar repeatability. A change of more than 3.7 doubling doses of methacholine is required for clinical significance.  (+info)

Forced expiratory wheezes in a patient with dynamic expiratory narrowing of central airways and an oscillating pattern of the flow-volume curve. (5/1139)

Forced expiratory wheezes (FEW) are common and the pathogenesis of this phenomenon might involve fluttering of the airways, but this theory has not been confirmed in patients. We report a case of a patient with FEW and a normal FEV1 that showed a bronchoscopically confirmed collapse of the trachea and main stem bronchi during forced expiration. Superimposed to the flow-volume curve was an oscillating pattern with a frequency that corresponded well with the wheeze generated during forced expiration. The oscillating pattern in the flow-volume curve and the collapse of the major airways supports the theory of wheezes generated by fluttering airways during forced expiration. Although FEW may be found also in healthy subjects, flow limitation is essential for the generation of FEW. The inclusion of a forced expiratory maneuver in the clinical examination might therefore be helpful in guiding the diagnosis towards airways obstruction.  (+info)

Age-dependent altered proportions in subpopulations of tonsillar lymphocytes. (6/1139)

Age-related changes in functional subsets of lymphocytes may influence the potential to build up immune responses. In particular, the capacity of tonsillar lymphocytes to counter infections may be altered during ageing. In order to address this question we investigated the proportional distribution of several subsets of tonsillar T and B cells with regard to ageing. Tonsils were derived from 119 patients between 2 and 65 years of age. Lymphocyte subsets were monitored by three-colour fluorescence of relevant CD markers in flow cytometry. As a general tendency the percentage of CD3+ T cells steadily increased whereas that of CD19+ B cells decreased at the same time. No significant differences were observed between lymphocytes of patients with and without inflammatory history of the tonsils. The percentage of CD8+ T cells declined whereas that of CD4+ T cells increased during the same time span. CD45RA+ T cells increased during the first two decades of life and gradually decreased thereafter. In contrast, CD45RO+ T cells showed an opposite trend. No differences were seen in the population of CD3-/CD56+ natural killer (NK) cells. The mature B cell marker CD40 showed no significant changes during ageing. However, CD38+ B cells, representing B cells of late maturation stages, dramatically declined up to the age of 65. In a similar manner the CD5+ subpopulation of B cells decreased during ageing. Substantial changes in major tonsillar T and B cell populations as shown in this study may have an impact on the ageing process of the immune system.  (+info)

Birth weight, body mass index and asthma in young adults. (7/1139)

BACKGROUND: Impaired fetal growth may be a risk factor for asthma although evidence in children is conflicting and there are few data in adults. Little is known about risk factors which may influence asthma in late childhood or early adult life. Whilst there are clues that fatness may be important, this has been little studied in young adults. The relations between birth weight and childhood and adult anthropometry and asthma, wheeze, hayfever, and eczema were investigated in a nationally representative sample of young British adults. METHODS: A total of 8960 individuals from the 1970 British Cohort Study (BCS70) were studied. They had recently responded to a questionnaire at 26 years of age in which they were asked whether they had suffered from asthma, wheeze, hayfever, and eczema in the previous 12 months. Adult body mass index (BMI) was calculated from reported height and weight. RESULTS: The prevalence of asthma at 26 years fell with increasing birth weight. After controlling for potential confounding factors, the odds ratio comparing the lowest birth weight group (<2 kg) with the modal group (3-3.5 kg) was 1.99 (95% CI 0.96 to 4.12). The prevalence of asthma increased with increasing adult BMI. After controlling for birth weight and other confounders, the odds ratio comparing highest with lowest quintile was 1.72 (95% CI 1.29 to 2.29). The association between fatness and asthma was stronger in women; odds ratios comparing overweight women (BMI 25-29.99) and obese women (BMI >/=30) with those of normal weight (BMI <25) were 1.51 (95% CI 1.11 to 2.06) and 1.84 (95% CI 1. 19 to 2.84), respectively. The BMI at 10 years was not related to adult asthma. Similar associations with birth weight and adult BMI were present for wheeze but not for hayfever or eczema. CONCLUSIONS: Impaired fetal growth and adult fatness are risk factors for adult asthma.  (+info)

Pertussis vaccination and wheezing illnesses in young children: prospective cohort study. The Longitudinal Study of Pregnancy and Childhood Team. (8/1139)

OBJECTIVES: To examine the relation between pertussis vaccination and the prevalence of wheezing illnesses in young children. DESIGN: Prospective cohort study. SETTING: Three former health districts comprising Avon Health Authority. SUBJECTS: 9444 of 14 138 children enrolled in the Avon longitudinal study of pregnancy and childhood and for whom data on wheezing symptoms, vaccination status, and 15 environmental and biological variables were available. MAIN OUTCOME MEASURES: Episodes of wheezing from birth to 6 months, 7-18 months, 19-30 months, and 31-42 months. These time periods were used to derive five categories of wheezing illness: early wheezing (not after 18 months); late onset wheezing (after 18 months); persistent wheezing (at every time period); recurrent wheezing (any combination of two or more episodes for each period); and intermittent wheezing (any combination of single episodes of reported wheezing). These categories were stratified according to parental self reported asthma or allergy. RESULTS: Unadjusted comparisons of the defined wheezing illnesses in vaccinated and non-vaccinated children showed no significant association between pertussis vaccination and any of the wheezing outcomes regardless of stratification for parental asthma or allergy. Wheeze was more common in non-vaccinated children at 18 months, and there was a tendency for late onset wheezing to be associated with non-vaccination in children whose parents did not have asthma, but this was not significant. After adjustment for environmental and biological variables, logistic regression analyses showed no significant increased relative risk for any of the wheezing outcomes in vaccinated children: early wheezing (0.99, 95% confidence interval 0.80 to 1.23), late onset wheezing (0.85, 0.69 to 1.05), persistent wheezing (0.91, 0.47 to 1.79), recurrent wheezing (0.96, 0.72 to 1.26), and intermittent wheezing (1.06, 0.81 to 1.37). CONCLUSIONS: No evidence was found that pertussis vaccination increases the risk of wheezing illnesses in young children. Further follow up of this population with objective measurement of allergy and bronchial responsiveness is planned to confirm these observations.  (+info)

In establishing baseline practice across a range of sites and clinicians in the UK and Ireland, we have demonstrated variation in management of acute severe childhood wheeze. This exists in assessment and treatment, especially inhaled and intravenous bronchodilator selection, dosage and frequency, reflecting the paucity of evidence underpinning recommendations.. CPGs such as BTS/SIGN national guidance9 assist clinicians in healthcare decisions and are underpinned by best available evidence. CPs translate and clarify CPGs, including timing and dosage of treatment, and as a result they streamline management plans across handovers, reduce variability and errors in care, prompt use of best evidence, improve education, and potentially shorten length of stay.14 ,16 The CPGs we collected were based on BTS/SIGN guidance9 varying mainly in bronchodilator selection/dosage and system processes. Overall, 40% had a wheeze CP, representing an opportunity to share best practice. In future, CPs should ...
New data show that, by 6 years of age, patterns of wheezing and weakened lung function in children with asthma symptoms may be firmly established. Reporting in the American Journal of Respiratory and Critical Care Medicine (November 2005), researchers have found that these patterns do not change dramatically for at least a decade. For the study, the children were classified into 4 types of wheezers. Of the 826 patients, 425 were never wheezers, 164 were transient early wheezers, 113 were persistent wheezers, and 124 were late-onset wheezers. The researchers conducted follow-ups at ages 8, 11, 13, and 16 years. The findings indicated that ,75% of the never wheezers and transient early wheezers reported no wheezing between 8 and 16 years. Of the children in the 2 groups that reported wheezing, most experienced only infrequent episodes. As we published in an earlier paper, transient early wheezers start life with levels of lung function that are significantly lower than those of ...
BACKGROUND: A study was undertaken to evaluate the reliability of a digital tracheal sound analyser (ELENS-DSA) in predicting nocturnal changes in airways resistance in asthmatic patients. This device allows continuous measurement of the proportion of the time occupied by wheezing (Wh%). METHODS: Nocturnal polygraphic studies with simultaneous continuous monitoring of tracheal sounds and airways resistance were performed in seven patients with nocturnal asthma. In order to evaluate the possible bias in wheezing estimation, each tracheal sound recording was passed through the automatic analyser and simultaneously monitored with earphones by an experienced observer. RESULTS: The device detected audible wheezing with an optimal sensitivity and specificity of 70%. Snoring was a minor cause of the relatively poor characteristics of the system. A close correlation (p , 0.001) between Wh% and airways resistance was observed only in those patients with the highest increase in resistance; when the ...

The reliability of diagnoses made in accident and emergency departments in epidemiological studies has been questioned.12 21 In children, especially those under the age of 2 years, the clinical distinction between conditions such as atopic and non-atopic asthma, wheezy bronchitis, and bronchiolitis may be impossible to make with certainty. Also at issue is the degree to which attendance rates in accident and emergency departments reflect the prevalence of acute asthma in the community as a whole. At the Hillingdon hospital over 60% of childhood wheezy episodes are self referrals, a figure that remains relatively constant throughout the year.. The application of non-linear Poisson regression models may be the reason that our study showed significant events not previously observed. Some studies have used linear regression models; others have assumed that data conformed to a normal distribution. The models used in our study showed that sulphur dioxide has a positive log-linear association with the ...

Maternal omega-3 fatty acid supplementation during the third trimester of pregnancy decreases a childs risk for persistent wheeze and asthma, a new study has suggested.
Hay fever symptoms are very common in young people but can be less troublesome as you get older. At present, it is not possible to predict whose hay fever will get better and whose will remain. Some patients will go on to develop asthma, which is commonly recognised as a persistent wheeze and may require specific treatment. ...
In Study II we investigated which subtypes of RV were detected during the acute phase, and the change in RV-specific IgG1 between the acute visit and a follow-up three months later. It is currently debated whether or not RV-C is more pathogenic than RV-A and RV-B. RV-C was the most frequently detected subtype, but we found no correlation between RV subtypes and clinical symptoms, or RV-specific IgG1 increase at follow-up. Children with an increase in specific IgG1 against both RV-A and RV-C, reported the longest duration of respiratory symptoms, indicating a possible synergistic effect of two RV subtypes and possibly an increased risk of asthma ...

Respiratory sound analysis is a simple and noninvasive way to study the pathophysiology of the upper airway (UA). Recently, it has been used to diagnose partial or complete UA collapse in patients with obstructive sleep apnea (OSA). In this study, we investigated whether fluid accumulation in the neck alters the properties of respiratory sounds in temporal and spectral domains and whether the respiratory sounds analysis can be used to monitor variations in the physiology of the UA, as rejected by UA resistance (R(UA)). We recorded respiratory sounds and R(UA) from 19 individuals while awake. We applied lower body positive pressure (LBPP) to shift fluid out of the legs and into the neck, which increased R(UA). We calculated first and second formants and energy of inspiratory sound segments. Our results show that during both control (no LBPP) and LBPP arms of the study, the extracted features were different for the sound segments corresponding to low and high R(UA). Also, the features were ...

Background: The prevalence of asthma and wheeze is increasing. Aim: To study the annual and cumulative prevalence of asthma and wheeze in 5-y-old Danish children. Methods: We obtained data on 3052 (82.0% of eligible) Danish children by a postal parental questionnaire including ISAAC questions regarding respiratory symptoms and our own questions on sociodemography and tobacco exposure. Results: Wheeze ever was reported in 38.3%, doctor-diagnosed asthma ever in 10.5%, childhood bronchitis ever in 30.0%, current wheeze (,12 mo) in 19.7%, and being severe (,3 episodes) in 3.9% of the children. Current wheeze was associated with male gender (OR 1.63, 95% CI 1.35-1.96), low parental post-primary education (OR 1.29, 95% CI 1.02-1.63 for ,3 y vs ≥3 y) and current maternal smoking (OR 1.69, 95% CI 1.39-2.04). Severe current wheeze was recognized as asthma in six and childhood bronchitis in three of 10 cases. Nearly all diagnosed asthmatics had suffered wheeze, two-thirds ...

In this study BMI was associated with asthma in both sexes in the representative sample but was only significantly associated in girls in the inner city sample. Generally, skinfold thickness odds ratios were lower than BMI in the representative sample but were similar in girls in the inner city sample.. As in all observational studies, information bias may have been a problem in our study. Information bias may partially explain the results but not the clear message that fatness, or a proxy measure of fatness, is associated with asthma in children. Parents perceptions of asthma in their child may vary according to ethnicity and social background. Persistent wheeze may be unrecognised as asthma in a large percentage of children from the ethnic minorities and inner city areas.23 In the NSHG we have not found an association between social class and obesity, but there are differences in fatness by ethnicity.24 Children from the Indian subcontinent tend to have lower weight-for-height and sum of ...
The Community-Based Intervention Project is structured to achieve Specific Aim 3: to test the hypotheses a) that community education can be effective in raising awareness of environmental health risks and preventive behaviors, thus in reducing the risk of asthma; and b) that individual maternal education to reduce exposure to ETS, a household intervention to reduce allergen exposures, and antioxidant supplementation will reduce the risk of asthma- related biomarkers and persistent wheeze among infants in the cohort identified as high risk based on elevated immunoglobulin (IgE) at 24 months. Low income communities lack adequate information or resources to prevent or reduce either community wide or personal exposures to these environmental health hazards. To address these problems the CCCEH proposes two related interventions, one at the community-level and one at the household level. Beginning in the first year, the Center will work in partnership with community organizations to develop, ...
Aim: To study the impact of study design on the incidence rates of asthma and wheeze during the teen ages.. Method: In a longitudinal study about asthma and allergic diseases within the OLIN studies in northern Sweden, a cohort of school children (n=3,430) was followed annually from age 7-8yrs by completion of an extended ISAAC questionnaire. In the endpoint survey (age 19yrs) 2,861 (83% of original responders) participated. Incident cases of asthma and wheeze from age 12 to 19yrs were identified by two methods: the annual questionnaire surveys and the endpoint survey only, respectively.. Results: The incidence was consistently higher when the incidence was based on annual surveys compared to the endpoint survey only. Based on the endpoint survey, the average annual incidence of current asthma, physician-diagnosed asthma and ever asthma was 0.7-1.4/100/y and current wheeze was 1.5/100/y. Based on the annual surveys, the incidence of asthma was 0.9-2.7/100/y and current wheeze 3.6-5.3/100/y. In ...

BACKGROUND: Asthma is common among adolescents, but there are few population-based studies on the risk factors for incident asthma and wheeze at this age group OBJECTIVE: To study risk factors for incident asthma and wheeze in adolescence.. METHOD: Within the Obstructive Lung Disease In Northern Sweden (OLIN) studies, a cohort of 3430 school children (age 7-8y) was recruited in 1996. In the present study, this cohort was followed from age 12 to 19y. At baseline (age 12y), 3151 participated and skin prick tests (SPT) were performed. The cohort was resurveyed annually and risk factors for the cumulative incidence of asthma and wheeze from age 12 to19y were analysed using multivariate Cox regression.. RESULTS: Female sex (wheeze: HR1.4 95%CI 1.2-1.6; asthma: HR1.8 95%CI1.2-2.5) and a positive SPT to cat, dog or horse at baseline (wheeze: HR 1.6 95%CI 1.2-2.1; asthma: HR2.3 95%CI 1.4-4.0) were significantly associated with the cumulative incidence of wheeze and asthma.

Background: Although most cases of asthma begin in early childhood, many children with wheeze do not develop persistent asthma. Frank and colleagues studied a cohort of children (initially younger than five years) for up to 11 years to identify predictors for persistent asthma.. The Study: The study was conducted by postal surveys of families in two large general practices in Manchester, England. Surveys were sent in 1993, 1995, 1999, 2001, and 2004 to all families with children younger than 16 years registered with the practices. Reminders were sent to nonresponders after four and eight weeks. The questionnaire was based on international studies of asthma and allergy in children, but used parent-reported wheezing as the key marker for respiratory disease. Parents were asked to report any wheeze or whistling-type respirations in their children by four features: (1) being woken by wheeze at least once per week; (2) speech interrupted by wheeze; (3) exercise-induced wheeze; and (4) more than three ...

Asthma in paediatric populations is one of the highest public health concerns. In this study of children and adolescents, we hypothesized that low levels of physical activity (PA) would show associations with asthma that vary by asthma outcome. The objective was to assess whether PA was associated with ever asthma and/or current asthma. Analyses were based on 4824 Danish schoolchildren aged 11-15 years old (48.7% boys) participating in the HBSC survey. The study variables were (1) physician-diagnosed asthma (ever asthma) and (2) physician-diagnosed asthma plus wheezing and/or physician or hospital consultation for wheezing (current asthma). Associations with PA by gender were analysed with multivariate logistic regression using the

A 1964 random community survey in Aberdeen of 2511 children aged 10-14 years identified 121 children with asthma and 167 with wheeze with infection. The outcome at age 34-40 years of these children with wheeze, together with that of 167 children selected from those who were asymptomatic, has been described.1 In 1995 we tried to contact the 2056 individuals (now aged 39-45 years) who had had no childhood wheezing; 1799 subjects were traced. We posted questionnaires about symptoms, smoking, and employment to 1758 surviving subjects, of whom 1542 (87.7%) responded (75.0% of 2056).. Attacks of wheezing ever were reported by 239 (15.5%) respondents, of whom 177 (11.5% of 1542) reported adult onset wheeze-that is, onset at or after age 15 years. The prevalence of adult onset wheeze was similar for men and women (10.7% v 13.0%, χ2=1.95, P=0.16). Other subjects reporting wheeze included 17 with onset at age 10-14 years, 27 with onset before age 10 years, and 18 with no age specified.. Of the 177 ...

In phase II, clusters of children were randomly selected in each centre for the study, using schools as sampling units. In Link ping, the survey involved 15 schools and in stersund all schools were selected due to the lower population. All 10-11 years old children (forms 4 and 5) were invited to participate in skin prick tests and parental questionnaires. Information on anthropometric measures at birth and pre- and perinatal exposures were collected from the medical birth registry. The local mass medias paid a great deal of attention to the study, particularly in stersund. The participation rates in the questionnaire study were 82% in Link ping and 86% in stersund. All children with a history of wheeze in the past 12 months as reported in the parental questionnaires and a random sample of non-wheezing children from the original cohorts were invited to a case-control study, which included parental questionnaire, examination for flexural dermatitis and bronchial challenge with hypertonic saline.. ...
