Sensory processing in young children with visual impairments:Use and extension of the Sensory Profile

Background: Children with visual impairments (VI) are at risk for sensory processing difficulties. A widely used measure for sensory processing is the Sensory Profile (SP). However, the SP requires adaptation to accommodate for how children with VI experience sensory information. Aims: (1) To examine sensory processing patterns in young children with VI, (2) to develop VI-specific items to use in conjunction with the SP and to determine internal consistency and construct validity of these newly developed items, and (3) to examine the association between sensory processing and and emotional and behavioral problems. Methods: Twenty-six VI-specific items were added to the SP. The SP and these items were completed by caregivers of 90 children with VI between 3 and 8 years old. The Child Behavior Checklist (CBCL) was used to assess emotional and behavioral problems. Results: Three- to five-year-old children with VI have significantly more difficulties in three quadrants of the SP as compared to the norm group. Six- to eight-year-old children with VI have more difficulties in all quadrants. A reliable and valid VI-specific set of 15 items was established following psychometric evaluation. Age-related differences were found in the associations between the SP and CBCL. Conclusion: Although further validation is recommended, this evaluation of the VI-specific item set suggests it has the potential to be a useful measure for children with VI

Associations of airway inflammation and responsiveness markers in non asthmatic subjects at start of apprenticeship

<p>Abstract</p> <p>Background</p> <p>Bronchial Hyperresponsiveness (BHR) is considered a hallmark of asthma. Other methods are helpful in epidemiological respiratory health studies including Fractional Exhaled Nitric Oxide (FENO) and Eosinophils Percentage (EP) in nasal lavage fluid measuring markers for airway inflammation along with the Forced Oscillatory Technique measuring Airway resistance (AR). Can their outcomes discriminate profiles of respiratory health in healthy subjects starting apprenticeship in occupations with a risk of asthma?</p> <p>Methods</p> <p>Rhinoconjunctivitis, asthma-like symptoms, FEV1 and AR post-Methacholine Bronchial Challenge (MBC) test results, FENO measurements and EP were all investigated in apprentice bakers, pastry-makers and hairdressers not suffering from asthma. Multiple Correspondence Analysis (MCA) was simultaneously conducted in relation to these groups and this generated a synthetic partition (EI). Associations between groups of subjects based on BHR and EI respectively, as well as risk factors, symptoms and investigations were also assessed.</p> <p>Results</p> <p>Among the 441 apprentice subjects, 45 (10%) declared rhinoconjunctivitis-like symptoms, 18 (4%) declared asthma-like symptoms and 26 (6%) suffered from BHR. The mean increase in AR post-MBC test was 21% (sd = 20.8%). The median of FENO values was 12.6 ppb (2.6-132 range). Twenty-six subjects (6.7%) had EP exceeding 14%. BHR was associated with atopy (p < 0.01) and highest FENO values (p = 0.09). EI identified 39 subjects with eosinophilic inflammation (highest values of FENO and eosinophils), which was associated with BHR and atopy.</p> <p>Conclusions</p> <p>Are any of the identified markers predictive of increased inflammatory responsiveness or of development of symptoms caused by occupational exposures? Analysis of population follow-up will attempt to answer this question.</p

Pretjerana bronhalna reaktivnost u kuharica i čistača

The aim of this cross-sectional study was to assess the prevalence and characteristics of bronchial hyperresponsiveness (BHR) in 43 women cleaners (aged 26 to 57) and 37 women cooks (aged 29 to 55) and compare them with 45 controls (women office workers aged 27 to 58). The evaluation of all subjects included a questionnaire, skin prick tests to common aeroallergens, spirometry, and histamine challenge (PC20≤8 mg mL-1). We found higher BHR prevalence in cleaners and cooks than in office workers (30.2 % and 29.7 %, vs. 17.7 %, respectively), but statistical significance was not reached. The prevalence of mild and moderate to severe BHR was similar in all groups. Borderline BHR prevalence was significantly higher in cleaners than in controls (16.2 % vs. 6.6 %, P=0.032) whereas the difference was on the verge of significance in cooks (13.5 % vs. 6.6 %, P=0.081). Moderate to severe BHR was strongly associated with positive family history of asthma and atopy in all groups. Mild BHR was significantly associated with daily smoking in cleaners (P=0.031) and cooks (P=0.021), as well as with the duration of exposure in cleaners (P=0.038). Borderline BHR was closely related to daily smoking and duration of exposure in both cleaners and cooks. Our findings indicate an important role of workplace exposure in borderline BHR development, as well as the significant effect of smoking on mild BHR development in women cleaners and cooks.Svrha je ovoga presječnog ispitivanja bila utvrditi prevalenciju i značajke pretjerane bronhalne reaktivnosti (engl. bronchial hyperresponsiveness, krat. BHR) u profesionalnih čistačica (43 ispitanice u dobi od 26 do 57 godina) i kuharica (37 ispitanica u dobi od 29 do 55 godina). Kontrolna skupina obuhvatila je 45 uredskih radnica u dobi od 27 do 58 godina. Ocjena izloženih i kontrolnih ispitanica obuhvatila je upitnik, skin prick testove na uobičajene inhalacijske alergene, spirometriju te histaminski test (PC20 ≤8 mg mL-1). ^istačice odnosno kuharice iskazale su veću prevalenciju BHR-a od kontrolnih uredskih radnica (30,2 % odnosno 29,7 % prema 17,7 %), ali ona nije bila statistički značajna. Sve su skupine iskazale podjednaku prevalenciju umjerenog i snažnog BHR-a. Prevalencija graničnoga BHR-a bila je značajno viša u čistačica negoli u kontrole (16,2 % naprema 6,6 %, P=0,032), a na rubu statističke značajnosti bila je i razlika između kuharica i kontrole (13,5 % prema 6,6 %, P=0,081). Umjeren odnosno snažan BHR u svih je skupina bio značajno povezan s obiteljskom povijesti astme i atopija. Blagi BHR značajno je povezan sa svakodnevnim pušenjem u čistačica (P=0,031) i kuharica (P=0,021), a u čistačica i s trajanjem izloženosti (P=0,038). Granični BHR je i u čistačica i u kuharica povezan sa svakodnevnim pušenjem i trajanjem profesionalne izloženosti. Naši podaci upućuju na važnu ulogu profesionalne izloženosti u nastanku graničnoga BHR-a te na značajan utjecaj pušenja na nastanak blagoga BHR-a u profesionalnih čistačica i kuharica
