ObjectiveThe aim of this study is to identify the most appropriate threshold for Disruptive Mood Dysregulation Disorder (DMDD) diagnosis and the impact of potential changes in diagnostic rules on prevalence levels in the community.MethodTrained psychologists evaluated 3,562 pre-adolescents/early adolescents from the 2004 Pelotas Birth Cohort with the Development and Well-Being Behavior Assessment (DAWBA). The clinical threshold was assessed in three stages: symptomatic, syndromic and clinical operationalization. The symptomatic threshold identified the response category in each DAWBA item which separates normative misbehavior from a clinical indicator. The syndromic threshold identified the number of irritable mood and outbursts needed to capture pre-adolescents/early adolescents with high symptom levels. Clinical operationalization compared the impact of AND/OR rules for combining irritable mood and outbursts on impairment and levels of psychopathology.ResultsAt the symptomatic threshold, most irritable mood items were normative in their lowest response categories and clinically significant in their highest response categories. For outbursts some indicated a symptom even when present at only a mild level, while others did not indicate symptoms at any level. At the syndromic level, a combination of 2 out of 7 irritable mood and 3 out of 8 outburst indicators accurately captured a cluster of individuals with high level of symptoms. Analysis combining irritable mood and outbursts delineated non-overlapping aspects of DMDD, providing support for the OR rule in clinical operationalization. The best DMDD criteria resulted in a prevalence of 3%.ConclusionResults provide information for initiatives aiming to provide data-driven and clinically oriented operationalized criteria for DMDD.

Objective: To distinguish normative fears from problematic fears and phobias. Methods: We investigated 2,512 children and adolescents from a large community school-based study, the High Risk Study for Psychiatric Disorders. Parent reports of 18 fears and psychiatric diagnosis were investigated. We used two analytical approaches: confirmatory factor analysis (CFA)/item response theory (IRT) and nonparametric receiver operating characteristic (ROC) curve. Results: According to IRT and ROC analyses, social fears are more likely to indicate problems and phobias than specific fears. Most specific fears were normative when mild; all specific fears indicate problems when pervasive. In addition, the situational fear of toilets and people who look unusual were highly indicative of specific phobia. Among social fears, those not restricted to performance and fear of writing in front of others indicate problems when mild. All social fears indicate problems and are highly indicative of social phobia when pervasive. Conclusion: These preliminary findings provide guidance for clinicians and researchers to determine the boundaries that separate normative fears from problem indicators in children and adolescents, and indicate a differential severity threshold for specific and social fears.

OBJECTIVE: To evaluate inhaler technique in outpatients with asthma and to determine associations between the correctness of that technique and the level of asthma control. METHODS: This was a cross-sectional study involving patients > 14 years of age with physician-diagnosed asthma. The patients were recruited from the Asthma Outpatient Clinic of the Hospital de Clínicas de Porto Alegre, in the city of Porto Alegre, Brazil. The patients completed two questionnaires (a general questionnaire and an asthma control questionnaire based on the 2011 Global Initiative for Asthma guidelines), demonstrated their inhaler technique, and performed pulmonary function tests. Incorrect inhaler technique was defined as the incorrect execution of at least two of the predefined steps. RESULTS: We included 268 patients. Of those, 81 (30.2%) showed incorrect inhaler technique, which was associated with poor asthma control (p = 0.002). Logistic regression analysis identified the following factors associated with incorrect inhaler technique: being widowed (OR = 5.01; 95% CI, 1.74-14.41; p = 0.003); using metered dose inhalers (OR = 1.58; 95% CI, 1.35-1.85; p < 0.001); having a monthly family income < 3 times the minimum wage (OR = 2.67; 95% CI, 1.35-1.85; p = 0.008), and having > 2 comorbidities (OR = 3.80; 95% CI, 1.03-14.02; p = 0.045). CONCLUSIONS: In the sample studied, incorrect inhaler technique was associated with poor asthma control. Widowhood, use of metered dose inhalers, low socioeconomic level, and the presence of > 2 comorbidities were associated with incorrect inhaler technique. OBJETIVO: Avaliar a técnica inalatória em pacientes com asma atendidos ambulatorialmente, estabelecendo associações dessa com o grau de controle da doença. MÉTODOS: Estudo transversal envolvendo pacientes com idade > 14 anos e diagnóstico médico de asma, recrutados no Ambulatório de Asma do Hospital de Clínicas de Porto Alegre, na cidade de Porto Alegre (RS). Os pacientes completaram dois questionários (um geral e um questionário de controle da asma baseado nas diretrizes da Global Initiative for Asthma de 2011). Os pacientes demonstraram a técnica inalatória e realizaram testes de função pulmonar. A técnica inalatória incorreta foi definida como a execução incorreta de pelo menos duas etapas da avaliação. RESULTADOS: Foram incluídos 268 pacientes. Desses, 81 (30,2%) apresentaram técnica inalatória incorreta, que foi associada com falta de controle da asma (p = 0,002). A regressão logística identificou os seguintes fatores associados com a técnica inalatória incorreta: ser viúvo (OR = 5,01; IC95%, 1,74-14,41; p = 0,003); utilizar inalador pressurizado (OR = 1,58; IC95%, 1,35-1,85; p < 0,001); ter renda familiar mensal < 3 salários mínimos (OR = 2,67; IC95%, 1,35-1,85; p = 0,008); e ter > 2 comorbidades (OR = 3,80; IC95%, 1,03-14,02; p = 0,045). CONCLUSÕES: Na amostra estudada, a técnica inalatória incorreta se associou com a falta de controle da asma. Viuvez, uso de inalador pressurizado, baixo nível socioeconômico e presença de > 2 comorbidades se associaram à técnica inalatória incorreta.

To evaluate the effect of a short-term individualized education program on adherence to asthma treatment, inhalation techniques, and asthma control.A prospective study involving patients aged 14 years or older, with a confirmed diagnosis of asthma and recruited from the asthma outpatient clinic of a university hospital in the city of Porto Alegre, Brazil. The study was conducted in two phases (before and after the educational intervention). At a routine medical visit, the participants completed a general questionnaire in order to assess the level of asthma control and inhalation techniques. The participants also underwent pulmonary function testing. Subsequently, they participated in an asthma education program, which consisted of one individualized session. The participants were reevaluated after three months.Of the 174 patients recruited, 115 completed the study. Between the first and second evaluations, there was a significant improvement in the effective use of inhaled corticosteroids (90.4% vs. 93.3%; p = 0.003), the effective use of long-acting β2 agonists (57.4% vs. 63.5%; p0.0001), the effective use of a combined regimen with these two medications (57.4% vs. 62.6%; p0.0001), and the self-reported adherence to corticosteroid therapy (p = 0.001). There was a significant decrease in the proportion of patients visiting ERs (30.4% vs. 23.5%; p = 0.012). However, the level of asthma control and the inhalation technique did not improve significantly (p = 0.095 and p = 0.512, respectively).This short-term asthma education program resulted in an improvement in the use of medications for asthma control and a decrease in the number of ER visits, although it had no significant effect on the inhalation technique.
