O impacto das reportagens divulgadas na internet relacionadas a casos de morte decorrentes de tratamento odontológico / The impact of articles published on the internet related to cases of death resulting from dental treatment

O presente estudo analisou reportagens não científicas veiculadas na internet, que divulgaram óbitos relacionados ao tratamento odontológico. Dezessete reportagens foram coletadas do site de busca Google®, utilizando-se palavras-chave específicas. Foram extraídas informações como: o ano e local de óbito; o sexo da vítima; o procedimento executado, dentre outras. A maioria dos pacientes eram do sexo feminino com idades entre 3 e 57 anos. A extração dental foi o procedimento mais vinculado aos óbitos. O presente estudo salienta a importância do planejamento clínico visando evitar situações inesperadas no consultório odontológico e chama atenção para as informações veiculadas pela mídia.

This study examined not scientific articles published on the internet which reported deaths related to Dental treatment. Seventeen reports were collected from the Google® search engine, using specific keywords. Several data were extracted, such as: the year and place of death; the victim's gender; the dental procedure performed, among others. Most patients were female aged between 3 and 57 years. Dental extraction was the most prevalent procedure. The present study highlights the importance of proper clinical planning in order to avoid unexpected situations in the routine of Dentistry; and suggests that the information reported by the non-scientific media must be carefully interpreted.

Allylation of functionalized aldehydes by potassium allyltrifluoroborate catalyzed by 18-crown-6 in aqueous media.

An efficient method for the allylation of aldehydes containing a broad range of functional groups using potassium allyltrifluoroborate is described. The reaction utilizes a catalytic amount of 18-C-6 in biphasic media under open atmosphere and room temperature to provide the corresponding homoallylic alcohols in high yields and without the necessity of any subsequent purification.

Liver overload in Brazilian triathletes after half-ironman competition is related muscle fatigue.

UNLABELLED: Triathlon competition is dependent on the athletes' ability to perform each discipline at optimal time, without excessive fatigue influencing the next one. OBJECTIVES: Determine the effects of a long distance triathlon on biochemistry parameters related to liver function. DESIGN AND METHODS: Blood samples from six athletes were collected before (T = 0) and immediately after the triathlon competition (T = 1). AST, ALT and alkaline phosphatase (ALP) values were assessed. RESULTS: Significant changes after triathlon competition were found for AST and ALP and no significant changes were found for ALT over time. CONCLUSIONS: A series of metabolically alterations, mainly related to energy production and also to muscle and skeletal adaptations occurs during and after strenuous exercise. The altered status of those metabolical changes cannot directly reflect the intensity of any possible muscular or hepatic damage or overload and elevated AST/ALT ratio is better associated to skeletal muscle lesion during competition.
