ABSTRACT
Abstract Objectives: Sialendoscopy is a minimally invasive procedure used to diagnose and treat obstructive salivary gland diseases. Previous studies in the topic have shown mixed results. The present study aimed to evaluate the efficacy and safety of sialendoscopy through previous systematic reviews for different outcomes of several diseases. We also aimed to assess studies' methodological quality and heterogeneity. Methods: We conducted a comprehensive systematic literature search of Pubmed, Embase, Lilacs and Cochrane Library. We included systematic reviews and meta-analyses that used sialendoscopy to treat both lithiasic and alithiasic salivary glands diseases. Data extraction included studies' characteristics and results. We assessed studies' methodological quality using the AMSTAR-2 (A Measurement Tool to Assess systematic Reviews 2) tool. Results: 13 studies were included in the review, being 9 in adult populations and 4 in pediatric populations. Sialendoscopy proved to be effective at the treatment of different lithiasic and other obstructive diseases, but with important heterogeneity. The technique was also considered highly safe in most studies. However, studies had a critically low quality of evidence. Conclusions: Most studies demonstrated high efficacy and safety of sialendoscopy, but with critically low quality of evidence. We still lack randomized studies in this field, and future systematic reviews on the topic should follow current guidelines to improve conduction and reporting.
ABSTRACT
O objetivo deste estudo foi conhecer a taxa de infecção pelo bacilo da Tuberculose entre estudantes dos dois primeiros e dois últimos períodos dos cursos de Medicina e Enfermagem da Universidade Estadual de Montes Claros, além de verificar o conhecimento sobre a transmissão e prevenção da tuberculose ocupacional, bem como a utilização destas medidas preventivas. Realizou-se estudo transversal, em que todos os estudantes dos dois períodos iniciais e dois períodos finais do curso de Medicina e de Enfermagem foram submetidos a um questionário padrão e ao teste tuberculínico (PPD), para determinar a prevalência de infecção por tuberculose. Os resultados mostraram diferença de reação ao teste tuberculínico nos estudantes dos períodos iniciais e finais do curso médico, enquanto nos estudantes de Enfermagem não houve diferença entre os períodos. Ficou evidenciado o limitado conhecimento sobre a transmissão e prevenção da aquisição de tuberculose, o que aumenta os riscos de aquisição do bacilo.
The study aimed to identify the tuberculosis infection rate among students from the first and last two years in the Schools of Medicine and Nursing at the State University in Montes Claros, Minas Gerais, Brazil, in addition to verifying their knowledge on transmission and prevention of occupational tuberculosis and the use of the recommended preventive measures. A cross-sectional study was conducted in which all the students from the first and last two years of Medicine and Nursing answered a standard questionnaire and had a tuberculin skin test (TST) to determine the prevalence of tuberculosis infection. The results showed a difference in the TST reactivity rate between the first and final years of medical school, while there was no difference in nursing students. The study revealed the students' limited knowledge concerning tuberculosis transmission and prevention, leaving them at increased risk of tuberculosis infection.
