Manejo farmacológico da hipertens?o arterial pulmonar
Ricachinevsky, Cláudia Pires;Amantéa, Sérgio Luís;

Abstract: objective: to perform a review of the diagnostic and therapeutic management of pulmonary hypertension in the pediatric population, with emphasis on pharmacological factors. sources: electronic search of publications on the medline/pubmed, lilacs and cochrane collaboration databases. the search strategy adopted gave priority to the identification of clinical trials (controlled or uncontrolled), systematic reviews and directives published during the last 10 years. summary of the findings: many advances have been incorporated into our understanding of pulmonary hypertension during recent years. issues related to differences in the pathophysiological mechanism of the disease between different age groups have altered both the treatment and prognosis of patients. the combined effect of more selective vasodilatory properties and antiproliferative action and the employment of new drugs are the basic principles of new treatment proposals. in order to be able to gauge the benefits associated with the use of these new therapies, it is of fundamental importance that all patients have their disease correctly diagnosed, the degree of functional compromise classified and their vascular reactivity capacity established, which is more difficult with pediatric patients. conclusions: to date there is no treatment that can be considered ideal for the management of pulmonary hypertension. with reference to the possibility of employing new drugs, the majority of studies that have been published were undertaken with adult populations. few data are available on children, and the majority of studies are uncontrolled trials or case series. taking into account differences that have already been established between different age groups in terms of disease mechanisms and prognostic aspects, it is difficult to claim that these drugs can be incorporated into the treatment of childhood pulmonary hypertension with the same indications and results.

Abstract: One hundred and one clerical and production workers in a steel trading company were enrolled in an open-label randomized controlled clinical trial (parallel groups) to compare the efficacy of an educational program for primary prevention of WMSD with control intervention. The primary outcome was a change in the physical functioning domain of the quality of life (QL) measured by Medical Outcomes Study Short Form 36 Health Survey (SF-36). The intervention group underwent six consecutive weekly sessions concerning specific orientations for the prevention of WMSD, while the control group received general health education in an identical schedule. The SF-36 and theses Work Limitation Questionnaire (WLQ) were evaluated at weeks zero, five and 26.Baseline characteristics of the interventions groups were comparable, and both groups comprised predominantly young healthy individuals. No significant differences in the variation of the SF-36 and WLQ between the groups were observed at weeks five and 26. However, both groups demonstrated improvement in some aspects of SF-36, suggesting that both educational interventions have beneficial impacts on QL.A specific educational program aimed at the preventing of WMSD was comparable with general health orientation for the improvement of QL and work capacity in a sample of healthy workers during a six month period.ClinicalTrials.gov: NCT00874718Work-related musculoskeletal disorders (WMSD) are a major concern for public health and frequently lead to temporary or permanent work incapacity [1,2]. The etiology of WMSD is complex, and includes ergonomic, individual, psychological and social factors [3-5]. In the USA, 4.26 million nonfatal work-related injuries and illnesses were reported in private industry during 2004, representing an incidence of 4.8 cases per 100 equivalent full-time workers. A significant portion of all events (1.26 million, 29.6%) were related to days spent away from work, and approximately 0.4 million of these were a

Amantéa, Daniela Vieira;Novaes, Ana Paula;Campolongo, Gabriel Denser;Barros, Tarley Pessoa de;
Acta Ortopédica Brasileira , 2004, DOI: 10.1590/S1413-78522004000300004
Abstract: the position of the head over the neck determines the posture of the body and is responsible for the body balance and head movements. the temporomandibular joint (tma) is directly related to the cervical and the scapular region by a common neuromuscular system. changes in the cervical spine can cause lead to tma disorders and contra wise. the increasing number of patients with tma disorders who also had postural disorders led to the development of studies to evaluate their interactions. the present study aimed to review the papers that have shown a relationship between wrong posture and tma disorders. it emphasizes the importance of a multidisciplinary team formed by an orthopedist, dental surgeon, and physiotherapist in the diagnosis and treatment of tma disorders and wrong posture.

Amantéa, Sérgio Luís;Sánchez, Ignacio;Piva, Jefferson Pedro;Garcia, Pedro Celiny Ramos;
Jornal de Pediatria , 2002, DOI: 10.1590/S0021-75572002000800006
Abstract: objective: to present a review of controversial issues related to the pharmacological management of the treatment of acute asthma in children. sources: articles published in national and international scientific journals. data were selected from lilacs and medline databases. summary of the findings: the article was organized into topics, presenting aspects on which there is consensus regarding the pharmacological treatment of asthma in children. issues related to the use of metered dose inhaler versus nebulizers, the role of ?2-adrenergic drugs administered intravenously as well as the role of methylxanthine and magnesium sulfate are approached critically. conclusions: inhaled ?2-agonist drugs combined with corticosteroids remain the treatment of choice for acute episodes of asthma in children. either nebulizers or metered dose inhalers connected to spacers are efficient for the relief of acute symptoms. patients who are refractory to conventional treatment and develop severe acute asthma should receive ?2-agonist drugs intravenously, provided they are properly monitored. methylxanthine and magnesium sulfate should be considered a second choice for selected patients.
