A simple tool to identify infants at high risk of mild to severe childhood asthma: the persistent asthma predictive score.

BACKGROUND: Recurrent wheezing in infants is a recognized risk factor for the development of childhood asthma. We sought to develop an easy-to-use persistent asthma predictive score (PAPS) in a population of young recurrent wheezers. METHODS: We retrospectively studied clinical and biological data of infants under 2 years of age presenting recurrent wheezing and evaluated current asthma at 6 years of age using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Multivariate analysis was performed to select predictive variables to generate a PAPS. The score was then tested on another cohort for independent validation. RESULTS: Two hundred infants were included in the cohort used to create the PAPS, and 227 in the validation cohort. In the first population, 47% of the children had developed asthma at 6 years of age, including 33% with mild to severe persistent asthma. Three parameters independently predicted persistent asthma: family history of asthma, personal atopic dermatitis, and multiple allergen sensitizations. Based on these variables, the PAPS showed 42% sensitivity, 90% specificity, 67% positive predictive value, and 76% negative predictive value for the prediction of persistent asthma. It was able to discriminate future persistent asthmatic from nonfuture persistent asthmatic children, with an accuracy of 74% in the initial population and 67% in the validation population. CONCLUSIONS: The PAPS, based on three easy-to-obtain variables, could help the physician in clinical practice to identify infants at high risk for persistent childhood asthma, and thus better evaluate the need for secondary preventive measures.

Implementation of a Medical Ethics Course in Undergraduate Dental Education and Assessment of Knowledge and Attitudes.

OBJECTIVES: A medical ethics course was launched in 2012 in a French University Dental School. We compared knowledge and attitudes, before and after implementation of that course. The aim of this study was to compare students who received an ethics course (third year) to those who did not have such training, however, most of them did have some clinical traineeship. MATERIALS AND METHODS: An anonymous questionnaire was sent to the second-, third-, and sixth-year students. It comprised questions with Likert item format answers and clinical vignettes with open responses. The results were analyzed by two approaches: a statistical analysis (chi-square or Fischer exact tests) and a content analysis using a predefined grid. RESULTS: A total of 299 respondents replied (75% students) the questionnaire. The analysis showed a statistically significant association between knowledge of the law and information procedures (P < 0.0001), access to medical files (P = 0.004), and recording consent (P = 0.049). It was also significant between knowledge of the law and the principles of biomedical ethics (P < 0.0001 for autonomy and beneficence). The third-year students could state the principles of medical ethics with their percentage always greater than the sixth-year students. After the third year, the students' attitudes switched from a social to a medical emphasis, and their point of view regarding patient's autonomy evolved. Patient's refusal of care raised potential conflicts between autonomy, professional judgment, information, and consent. CONCLUSION: Ethics teaching could offer a way to turn positive attitudes into real competencies and should be considered at an early stage.

Residual pulmonary vascular obstruction and recurrence after acute pulmonary embolism. A single center cohort study.

INTRODUCTION: Up to 50% of patients with pulmonary embolism (PE) present lung perfusion defects after six months of anticoagulant treatment, suggesting residual pulmonary vascular obstruction (RPVO). The risk of recurrence in patients with RPVO remains unknown. The present study aims to assess the risk of recurrent venous thromboembolism (VTE) in patients with RPVO after a first symptomatic episode of PE. METHODS: Consecutive patients who survived a first objectively proven acute PE, treated for at least three months with anticoagulants, were included and followed prospectively. RPVO was defined as a pulmonary vascular obstruction of >10% on ventilation/perfusion lung scan performed at inclusion. Objectively proven VTE recurrences were registered and confirmed by an investigator unaware of the result of the ventilation/perfusion lung scan. RESULTS: Among the 310 patients (median age: 61years) included in the study, 60 (19%) had RPVO. During a median follow-up of 51.3months, 66 patients (21.2%, 95% CI [17.5-26.7]) experienced recurrent VTE. In an adjusted cox proportional hazards analysis, we identified RPVO (HR 1.94; 95% CI [1.11-3.39]; p=0.026) and unprovoked PE (HR 3.56; 95% CI [1.79-7.07]; p=0.00051) as independent risk factors for recurrent VTE whereas extended anticoagulation therapy (HR 0.19; 95% CI [0.07-0.55]; p=0.00014) was associated with a low risk of recurrence. CONCLUSION: The results suggest that RPVO is an independent risk factor of recurrent VTE after a first PE.
