Background Early repolarization pattern (ERP) is considered a common training-related and benign ECG finding in young adult athletes. Few data exist on ERP in the pediatric athletes population. Therefore, we aimed to evaluate the ERP prevalence, characteristics, and prognosis in pediatric athletes aged ≤16 years. Methods and Results Eight-hundred eighty-six consecutive pediatric athletes engaged in 17 different sports (mean age, 11.7±2.5 years; 7-16 years) were enrolled and prospectively evaluated with medical history, physical examination, resting and exercise ECGs, and transthoracic echocardiography during their preparticipation screening. Known cardiovascular diseases associated with sudden cardiac death was considered exclusion criteria. Athletes were followed up yearly for 4 years. The prevalence of ERP was 117 (13.2%), equally distributed in both sexes ( P =0.072), irrespectively of body mass index and classification of sports. The most common ERP localizations were inferolateral and inferior leads (53.8% and 27.3%, respectively). Notching J-point morphology was the most prevalent (70%), and rapidly ascending ST elevation (96%) was the most common ST-segment morphology. Athletes with ERP were older ( P <0.001) had lower rest and recovery heart rates ( P <0.001), increased precordial and limb R-wave voltages ( P <0.001), increased R/S Sokolow index ( P <0.001), and longer PR interval ( P =0.006) in comparison with the athletes without ERP. Neither major cardiovascular nor arrhythmic events, nor sudden cardiac death were recorded over a median follow-up of 4.2 years. One hundred seventeen (80.3%) athletes with ERP exhibited a persistent ERP. ERP localization and J-point morphology changed during follow-up in 11 (11.7%) and 17 (18%) of athletes, respectively. Conclusions ERP is common in pediatric athletes. It was mostly located in the inferolateral leads and associated with concave ascending ST segment with other training-related ECG changes. The lack of either sudden cardiac death or cardiomyopathies linked to sudden cardiac death over follow-up suggests that in pediatric athletes, ERP may be considered a benign training-related ECG phenomenon with a potential dynamic pattern.

There is an increasing pressure on occupational health professionals to ensure that their practice is based on a quality standard and an evidence of appropriateness. The efficacy-effectiveness of their activity strictly depends on their intellectual and professional integrity, their technical and legal competence, but also on the quality of the relations with the company organisation they are able to establish. We asked to some occupational physician when they considered their interventions in the workplace to be efficacious. Then, accordingto our epexrience, we propose some effectiveness indicators, particular concerning health surveillance and health educttaon, that should be evaluated to verify the health professional agccvity agreement to quality standards.

The "competent" doctor is much interested in the extensive application of the article 35 of DPR 303/56. As a matter of fact, that permits him a sanitary surveillance less concerned in formal performances and more related to work risk. The employers are often reluctant to require the derogation foreseen by the article 35 of DPR 303/56 because from such a request interventions on part the vigilance organ could derive causing instruction report report, notices and sanctions regarding situation independent from the risk which the derogation was requested. As a result, the modality for the derogation application has to be uniform all over the territory: an action at regional level is strictly necessary as well as check activity on part of the competent offices of the region.

A working group of the Occupational Medicine and Industrial Hygiene Association of Lombardy, the National Association of Occupational Health Physicians the National Society of Prevention Operators made a paper in order to rationalize the sanitary surveillance, observing the laws in force and following the European Directives. The authors, thinking that everyday experience not very useful health examinations are carried out and that the sanitary surveillance should be planned according to the real working risks, give methodological directives about the way to make the mandatory clinical examinations less frequent, to the firms, to the occupational health physician and to the public occupational health operators of the local health units that must supervise the sanitary surveillance.

The author analyzes the role of the workphysician in order to the new laws of prevention, safety and health promotion on the work-places. Especially, the author emphasizes the synergic actions and the collaborations between workphysicians and public health structures, as the Hospital Units for Occupational Medicine.
