ABSTRACT
INTRODUCTION: Fractures in children and adolescents are a public health issue. However, reliable epidemiological descriptions of the South American population must be improved. This study aims to present epidemiological data on fractures from a children's orthopedic hospital in one of the five largest cities in Latin America. PATIENTS AND METHODS: Descriptive epidemiological data from 2015 to 2019 were used to characterize children's fractures. Demographic variables, the number of fractured bones, high-energy trauma findings, fracture characteristics, fingertip injuries, and associated complications discriminated by the type of treatment are presented. Long bone fractures were classified according to the AO classification. All children less than 18 years of age were included. RESULTS: In a population of 3,616 children, 4,596 fractures were identified. More boys than girls sustain a fractured bone, with ratios as high as 6:1 around 15 years old. Distal forearm fractures were the most common (31.9%), followed by distal humerus (20.2%). Most of the complications were related to these two sites of fractures. The OR of complications between surgical and conservative management was 2.86. CONCLUSION: Epidemiological data of fractures from the authors' institution display the usual trending reported in most populations. Gender-related and age-related differences were relevant. Most fractures and complications are related to upper limb low-energy trauma. The most frequent are loss of ROM and loss of reduction. LEVEL OF EVIDENCE: Level III - retrospective cohort study.

Osteogenesis imperfecta (OI) is a hereditary disease of connective tissue characterized by the loss of bone density and mass, which increases the fragility of the bones, thus presenting multiple fractures throughout the years followed by bone deformity and articular instability. This condition has various clinical presentations. We present four cases of OI, one case with type I, two cases with type II, and one case with type III. The clinical diagnosis in most of the cases was clinical; only one of them was confirmed with genomic sequence. The treatment of these cases was based on medication, orthopedic surgery, and recovery and physical therapy. The evolution was torpid in these cases but with prolonged life expectancy despite the severity and type of OI. It is important to highlight that the patients did not have a neurocognitive compromise. Early diagnosis and multidisciplinary medical management are crucial in obtaining better outcomes for this disease, improving the quality of life, and avoiding complications.
ABSTRACT
RESUMEN Las vacunas son productos biológicos que contienen antígenos que buscan generar protección contra a la exposición real de un agente patógeno. En cuanto a su importancia, hacen parte de las intervenciones más costo-efectivas en salud pública, siendo superadas únicamente por el agua potable. A grandes rasgos, podemos dividir las vacunas en vivas atenuadas e inactivadas; no obstante, el nuevo coronavirus ha producido la emergencia de plataformas innovadoras que utilizan mecanismos intracelulares y moleculares con el mismo objetivo de generar inmunidad. Se realizó una búsqueda sistemática de la literatura utilizando las bases de datos electrónicas Pubmed, Scopus y Web of Science. Todos los tipos de diseño de estudio fueron considerados, sin embargo, se prefierieron aquellos redactados en idioma inglés o español. Se hace una revisión de la literatura presente sobre las plataformas existentes para generar inmunidad frente al coronavirus SARS-CoV-2 y se desarrolla cada una según su ruta y forma de acción en aquellas basadas en subunidades proteicas, vector viral recombinante, ácidos nucleicos, virus inactivados, partículas virales y virus vivos atenuados. Los mecanismos por los cuales dichas vacunas generan inmunogenicidad son diferentes, no obstante, la constante inserción de mutaciones por parte del virus sigue siendo un objeto de interés y preocupación por los investigadores.
ABSTRACT Vaccines are biological products containing antigens that aim to generate protection against real exposure to an infectious pathogen. They constitute the most cost-effective interventions in public health, being surpassed only by drinking water. Generally speaking, we can divide the vaccines into live attenuated and inactive; However, the new coronavirus has produced innovative platforms that use intracellular and molecular mechanisms with the same objective of generating immunity. A systematic literature search was carried out using the PUBMED, SCOPUS, and Web of Science electronic databases. All types of study design were selected, those written in English or Spanish were prioritized. We reviewed the existing platforms to generate immunity against the SARS-CoV-2 coronavirus. Each one is developed according to its route and form of action, and can be classified as protein subunits, recombinant viral vector, nucleic acids, inactivated viruses, viral particles, and live attenuated viruses. The mechanisms by which these vaccines generate immunogenicity are different; however, the constant insertion of mutations by the virus remains an object of interest and concern for researchers.
