RESUMEN
Introduction Traumatic brain injury (TBI) is among the main causes of death and neurological sequelae worldwide. Injuries are classified as diffuse (diffuse axonal injury and brain swelling) or focal (cerebral contusion [CCo], epidural hematoma, and acute subdural hematoma). Among all TBIs, CCos are the most frequent focal lesion, and treatment modalities are many. Hematoma evacuation using large craniotomies has been well described in the literature. The main goal of the present study is to discuss the advantages of minimally invasive approaches for the treatment of CCos, regarding operative time, blood loss, and postoperative tomographic results. Methods An integrative literature review was conducted on the SciELO, LILACS, and PubMed databases. Seven case reports were included in the present study. Retrospective data collection was performed, analyzing gender, age, Glasgow coma scale score on hospital admission, surgical approach, and postoperative (tomographic) results. Results The minimally invasive keyhole approach was used in seven patients with CCos. The supraorbital approach (n » 5) was performed for frontal lobe contusions, and the minipterional approach (n » 2) was performed for temporal lobe contusions. All cases had adequate hematoma evacuation, confirmed by postoperative computed tomography scans. Conclusion The minimally invasive approaches were effective for hematoma evacuation, with adequate clinical and radiological postoperative results.
Introdução O traumatismo cranioencefálico se encontra entre as principais causas de óbito e sequelas neurológicas na estatística mundial. As lesões são classificadas como difusas (lesão axonal difusa e edema cerebral traumático) ou focais (contusões cerebrais [CoC], hematoma epidural, e hematoma subdural agudo). Dentre todos os tipos de lesões cerebrais traumáticas, as contusões são a lesão focal mais comum, e são reservadas a elas múltiplas modalidades de tratamento. O principal objetivo desse estudo é discutir as vantagens dos acessos minimamente invasivos no tratamento de contusões cerebrais, especialmente no que concerne à duração do procedimento, perda sanguínea e resultados tomográficos pós-operatórios. Métodos Uma revisão integrativa de literatura foi conduzida nas plataformas Scientific Electronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e PubMed. Sete relatos de caso foram incluídos neste estudo. A coleta retrospectiva de dados foi realizada com a análise das seguintes variáveis: gênero, idade, escala de coma de Glasgow à admissão, acesso cirúrgico utilizado e resultados tomográficos pós-operatórios. Resultados O acesso cirúrgico minimamente invasivo foi utilizado em sete pacientes com CoC. O acesso supraorbital (n » 5) foi usado para tratar contusões frontais, enquanto o acesso minipterional (n » 2) foi usado para o tratamento de contusões temporais. Em todos os casos, foi obtida drenagem satisfatória do hematoma, confirmada por meio de tomografias pós-operatórias. Conclusão Os acessos minimamente invasivos foram efetivos para evacuação dos hematomas intraparenquimatosos, com resultados clínicos e tomográficos favoráveis.
RESUMEN
INTRODUCTION: The varicella vaccine was first introduced into the Brazilian immunization schedule in September 2013 as a single dose for children aged 15 months. In 2018, a second dose was recommended for individuals between 4 and 6 years old. This study aims to assess the impact of routine varicella vaccination on the number and profile of hospitalized varicella patients during the single dose period, as well as in the first two years after the adoption of the second dose. METHODS: An observational retrospective study was conducted in an infectious disease pediatric hospital, in Minas Gerais, Brazil. Clinical as well as epidemiological data from patients hospitalized due to varicella between 2010 and 2019 were collected. Patients were split into groups based on the vaccine introduction: pre-vaccine period, single dose and two-dose period. They were compared by age, sex, reason for admission, illness-related complications and clinical outcome. RESULTS: There were 1193 admissions due to varicella during the studied period. When compared with the pre-vaccine period, the number of hospitalizations decreased in 61.5% during the single-dose regime, reaching 95.2% in the two-dose period. Hospitalization rates decreased in all age groups, including non-vaccinated individuals such as those younger than 12 months (92.1%). As for reasons of admission, secondary bacterial skin infections were perceived to be the most common cause (>70%). A reduction was also seen in admission of immunocompromised or HIV positive patients (84.8%). CONCLUSION: The collected data shows a significant impact in the number of hospital admissions due to varicella after six years of the implementation of the vaccine, positively affecting both vaccinated and non-vaccinated individuals. Further reduction was seen after the second dose was initiated, but its true impact will only be understood fully after a longer period of continuous vaccination.
