Hepatotórax crônico devido à ruptura do diafragma direito: um desafio anestésico em um caso raro

Background

Diaphragmatic rupture is an uncommon condition, with 90% of ruptures occurring on the left side. However, its incidence on the right side is increasing along with the increase in traffic accidents. Liver herniation may become progressive causing severe atelectasis of the right lung, resulting in impaired respiratory status and hemodynamic changes.

Influência da dose de propofol e dos componentes sanguíneos na duração das convulsões elétricas em eletroconvulsoterapia

Background and objectives

Propofol is commonly employed as a hypnotic agent to perform electroconvulsive therapy, but it exhibits also anticonvulsant properties. The main objective was to study the effect of the weight‐adjusted dose of propofol on duration of the electrical seizure. Secondary objectives were to study the effect of absolute dose of propofol on duration of electrical seizure, the effect of both absolute and weight‐adjusted doses on values of bispectral index, and the influence of blood chemistry on anticonvulsant effect.

Anestesia e doença de Alzheimer – Percepções atuais

Background and objectives

It has been speculated that the use of anesthetic agents may be a risk factor for the development of Alzheimer disease. The objective of this review is to describe and discuss pre‐clinical and clinical data related to anesthesia and this disease.

In vitro bond strength of an epoxy resin-based root canal sealer to root dentin irradiated with high-power lasers and adhesive interface analyses

The aim of this study was to evaluate in vitro the influence of high-power lasers (Nd:YAG and diode 980 nm) associated with mineral coal as fotopotencializer on bond strength of an epoxy resin-based root canal sealer to root dentin, using the pushout test, and on the dentin/filling material interface, using confocal laser microscopy. For this purposes, 50 canines were instrumented with Mtwo rotary system up to #50.04 instrument and randomly assigned to five groups (n = 10): group I—control EDTAC; group II—EDTAC and Nd:YAG laser; group III—EDTAC and diode laser 980 nm; group IV—EDTAC, Nd:YAG laser and mineral coal 5 g/100 mL; and group V—EDTAC, diode laser 980 nm and mineral coal 5 g/100 mL. All data were analyzed by ANOVA (at 5% significance level) following the Kruskal-Wallis, Dunn and Tukey tests. The group I increased more bond strength of the sealer to root dentin that treated with only EDTAC 17% (17.21 ± 21.75 MPa), similar to the group II (12.21 ± 18.20 MPa) and group IV (14.92 ± 28.06 MPa), both treated with Nd:YAG laser, with the exception of group IV, which was added to mineral coal. The group V (8.75 ± 13.42 MPa) had similar results to the groups II and IV, but the same similarity were found when compared with group III (7.11 + 11.28 MPa), with lower results. Regarding the root thirds, the apical third (23.27 ± 29.21 MPa) presented a statistically higher value on bond strength than the cervical third (5.92 ± 5.33 MPa) and middle third (6.93 ± 7, 11 MPa) (p > 0.05). Group II (86.27 μm) showed the highest tags penetration values, with a statistically difference to the group III (51.57 μm), IV (36.77 μm) and V (32.37 μm) (p < 0.05). Group I (71.63 μm) was statistically similar to groups II and III (p > 0.05). Group IV had the lowest values and was statistically similarity to groups III and V (p > 0.05). It was concluded that the treatment with Nd:YAG laser provides better results than the diode 980 nm laser, except when was added mineral coal. The control and diode 980 nm laser groups presented less adhesive failures and more mists failures than the other groups. Both lasers did not interfere negatively compared to the control group.     

Impact of Trauma System Structure on Injury Outcomes: A Systematic Review and Meta-Analysis

Background

The effectiveness of trauma systems in decreasing injury mortality and morbidity has been well demonstrated. However, little is known about which components contribute to their effectiveness. We aimed to systematically review the evidence of the impact of trauma system components on clinically important injury outcomes.

Methods

We searched MEDLINE, EMBASE, Cochrane CENTRAL, and BIOSIS/Web of Knowledge, gray literature and trauma association Web sites to identify studies evaluating the association between at least one trauma system component and injury outcome. We calculated pooled effect estimates using inverse-variance random-effects models. We evaluated quality of evidence using GRADE criteria.

Results

We screened 15,974 records, retaining 41 studies for qualitative synthesis and 19 for meta-analysis. Two recommended trauma system components were associated with reduced odds of mortality: inclusive design (odds ratio [OR] = 0.72 [0.65–0.80]) and helicopter transport (OR = 0.70 [0.55–0.88]). Pre-Hospital Advanced Trauma Life Support was associated with a significant reduction in hospital days (mean difference [MD] = 5.7 [4.4–7.0]) but a nonsignificant reduction in mortality (OR = 0.78 [0.44–1.39]). Population density of surgeons was associated with a nonsignificant decrease in mortality (MD = 0.58 [?0.22 to 1.39]). Trauma system maturity was associated with a significant reduction in mortality (OR = 0.76 [0.68–0.85]). Quality of evidence was low or very low for mortality and healthcare utilization.

Conclusions

This review offers low-quality evidence for the effectiveness of an inclusive design and trauma system maturity and very-low-quality evidence for helicopter transport in reducing injury mortality. Further research should evaluate other recommended components of trauma systems and non-fatal outcomes and explore the impact of system component interactions.

Prevalence of autoantibodies in the course of Gaucher disease type 1: A multicenter study comparing Gaucher disease patients to healthy subjects

Objectives

Type 1 Gaucher disease may be related to the presence of autoantibodies. Their clinical significance is questioned.Primary endpoint was to compare the prevalence of autoantibodies in type 1 Gaucher disease patients with healthy subjects, seeking correlations with autoimmune characteristics. Secondary endpoints were to determine whether patients with autoantibodies reported autoimmunity-related symptoms and if genotype, splenectomy or treatment influenced autoantibodies presence.
