The influence of personality traits and beliefs about medicines on adherence to asthma treatment.

Aim: To explore the influence of personality traits and beliefs about medicines on adherence to treatment with asthma medication.

Methods: Respondents were 35 asthmatic adults prescribed controller medication. They answered questionnaires about medication adherence, personality traits, and beliefs about medicines.

Relationship of airway sensory hyperreactivity to asthma and psychiatric morbidity.

Background: Patients with airway symptoms induced by chemicals and odors are common in allergy clinics, but the problems cannot be explained by allergic or asthmatic reactions. Previous studies have shown that these patients often have increased sensitivity to inhaled capsaicin, which is known to reflect sensory reactivity; a diagnosis of airway sensory hyperreactivity (SHR) has been suggested for this condition.

Objectives: To examine the relationship between asthma and SHR and to investigate whether patients with SHR show signs of increased psychiatric morbidity.

The Ringloc liner compared with the Hexloc liner in total hip arthroplasty.

The aim of this study was to compare the 10-year survival rate, pelvic osteolysis frequency and linear head penetration rate of the Hexloc and Ringloc liners used together with a partially threaded porous and hydroxyapatite coated cup and the Bi-Metric uncemented femoral stem. The 15-year results for the cup with the Hexloc liner are also reported. We included 332 consecutive hips (166 Hexloc and 166 Ringloc) on 281 patients in the study.

Prevalence and risk factors for chemical sensitivity and sensory hyperreactivity in teenagers.

The prevalence of chemical sensitivity (CS) and sensory hyperreactivity (SHR) was assessed in a teenage population. Among a random sample of 401 teenagers, 326 (81.3%) answered questionnaires assessing sensitivity to chemicals and noise, anxiety and depression.

Relationship between self-reported odor intolerance and sensitivity to inhaled capsaicin: proposed definition of airway sensory hyperreactivity and estimation of its prevalence.

Study Objectives: The aim of this study was to investigate the relationship between the behavioral consequences of self-reported odor sensitivity with the chemical sensitivity scale for sensory hyperreactivity (CSS-SHR) and cough sensitivity to inhaled capsaicin. We also wanted to estimate the prevalence of airway sensory hyperreactivity (SHR), which was defined as a positive CSS-SHR score in combination with a positive capsaicin inhalation test result.

Design: A general population-based study with randomly selected individuals after stratification for age and gender.

Detection of chronic rejection by quantitative ventilation scintigrams in lung-transplanted patients: a pilot study.

The suspicion of chronic rejection [bronchiolithis obliterans syndrome (BOS)] is usually based on deteriorating forced expired volume in 1 s. It is however, desirable to develop more sensitive methods as increased anti-inflammatory therapy is thought to stop progression of the rejection. The aim of the present study was to develop quantitative tools based on ventilation scintigrams, to diagnose BOS.

Effects of lung volume reduction surgery on distribution of ventilation and perfusion.

Lung volume reduction surgery (LVRS) results in functional improvements in most patients. The mechanisms behind the improvements are not clear. We hypothesized that reduced inequalities in ventilation to perfusion ratio (V/Q) may be a contributing explanation.

Regional ventilation and distribution of emphysema - a quantitative comparison.

The distribution of ventilation and emphysema throughout the lung was compared in 20 emphysematous patients who were candidates for lung volume reduction surgery. Ventilation distribution among 1.6-cm-high stripe regions was obtained in supine position by planar gamma camera scintigraphy after inhalation of technegas.
