Prognostic factors in civilian gunshot wounds to the head: a series of 110 surgical patients and brief literature review

Abstract: This study was carried out to evaluate the early results and the prognostic factors affecting the outcome during the in-hospital stay of 110 patients with civilian gunshot wounds to the head admitted at the Hospital of Restauracao, Recife, Brazil Penetrating injury (66%) was the most prevalent type of wound encountered in the present series Twelve of the 110 (109%) patients presented a unilateral dilated pupil at the admission Motor impairment was present in 24/110 (218%) patients Intracerebral hematoma was present in 36/110 (327%) and there were 15/110 (13%) patients with cerebrospinal fluid fistula Eleven of 110 patients developed meningitis and in 9/110 intracranial abscesses occurred Nine of 110 patients developed deep venous thrombosis, 11/110 had urinary infection, and coagulopathy was detected in 8/110 Following the surgical procedure, 27/110 (245%) patients died during their hospital stay When the two groups, survivors and non-survivors, were compared, there were significant statistical differences and the univariate analysis identified five preoperative predictors of a poor outcome following surgery: age over 40 years (odds ratios (OR) 54, 95% CI 173–1682); presence of unilateral pupil dilatation (OR 55, 95% CI 1641–1813); low (≤8) Glasgow coma score on admission (OR 650, 95% CI 227–1860), presence of intracranial hematoma (OR 30, 95% CI 121–734), and respiratory infection (OR 48, 95% CI 175–1347) Thus, (a) age of the patient (juvenile/young age), (b) high preoperative Glasgow coma score, (c) lack of pupil abnormalities, and (d) absence of intracerebral hematoma are predictors of a good prognosis

The effect of collagen removal and the use of a low-viscosity resin liner on marginal adaptation of resin composite restorations with margins in dentin.

Abstract: This study evaluated the influence of collagen removal and the use of a low-viscosity liner on the marginal quality of composite restorations for the total-etch system, Prime & Bond 2.1 (PB) and the self-etching primer system, Clearfil SE Bond (CSEB), in high C-factor cavities with margins in dentin. High C-factor cavities were made on dentin exposed from ground labial surfaces of 100 bovine lower incisors, randomly assigned to 10 treatment groups and restored with composite Z 250, placed in bulk. In Group 1 (PB), control group, PB was applied according to the manufacturer's directions; in Group 2 (PB/PLF), an intermediate layer of low-viscosity composite Protect Liner F (PLF) was applied on the bonding resin surface; in Group 3 (PB/SH) following acid-etching, the surfaces were treated with 10% sodium hypochlorite (SH) for one minute and in Group 4 (PB/SH/PLF), the same procedure was conducted as for Group 3, plus an intermediate layer of PLF was applied as for Group 2. In Group 5 (CSEB), the control group, CSEB was applied according to the manufacturer's directions; in Group 6 (CSEB/PLF), an intermediate layer of PLF was applied; in Group 7 (SH/CSEB), the cavity surface was pre-treated with SH; in Group 8 (SH/CSEB/PLF), SH pre-treatment was conducted as for Group 7, then an intermediate layer of PLF was applied; in Group 9 (CSEB/SH), after CSEB-primer application, the surface was treated with SH, followed by CSEB-adhesive application and in Group 10 (CSEB/SH/PLF), the same was conducted as for Group 9, then an intermediate layer of PLF was applied. The specimens were stored at 37 degrees C for 24 hours, polished, molded and replicas were obtained in epoxy resin. The replicas were gold-sputter coated and observed by SEM (300x) for marginal quality classification. The Kruskal-Wallis non-parametrical multi-comparison Test (p<0.05) was used to obtain statistical analysis of the data. Results demonstrated that both adhesive systems in the control groups presented low marginal quality and a high variability. The use of an intermediate layer of PLF significantly improved the marginal quality with the CSEB system but had no effect with the PB system. Collagen depletion with SH enhanced marginal quality for the PB system and did not influence the CSEB system results.

Study of the dung beetle (Coleoptera: Scarabaeidae) community at two sites: Atlantic forest and clear-cut, Pernambuco, Brazil.

Abstract: The aim of this study was to compare the dung beetle (Coleoptera, Scarabaeidae: Scarabaeinae) community structure at two sites in the Charles Darwin Ecological Refuge in Igarassu, Pernambuco, Brazil. Dung beetles were collected in 2006 using monthly samples from 48 pitfall traps baited with human dung and bovine carrion. The dung beetle communities from the study sites were compared in terms of abundance, species richness, and diversity (Shannon index). Seasonality was analyzed by Spearman correlation between rainfall data and community parameters. In total, 2,560 individuals belonging to 40 species, 16 genera, and 6 tribes were collected. Species richness was higher for the clear-cut area compared with the forest habitat. Estimators of species richness suggested a total richness of 42–47 species in the entire study area. A positive correlation was observed between monthly rainfall and total abundance of individuals for the clear-cut area but not for the forest habitat. This study contributes to a better understanding of Scarabaeinae ecology in the Atlantic rainforest of northeastern Brazil.

First description of KPC-2-producing Pseudomonas putida in Brazil

Abstract: This work reports the identification of the first case of a KΡC-2-producing Pseudomonas putida isolate (PP36) in Brazil. The PP36 isolate was resistant to all the antimicrobials tested except polymyxin B. In addition to the discovered bla KPC-2 gene, genetic analysis showed the presence of a class 1 integron containing the dhfr XVb gene and the new allele arr-6 , which codes for resistance to rifampin. These elements were found in an IncFI 65-kb plasmid.

Ansiedade frente ao tratamento odontológico: prevalência e fatores predictores em brasileiros

Abstract: Considering the negative impact anxiety can exert over dental treatment, the scope of this study was to determine the prevalence of predictors of anxiety regarding dental treatment among Brazilians. A cross-sectional study was carried out using the Corah dental anxiety scale to assess the degree of anxiety regarding dental treatment among 3000 patients. The results reveal that two out of every eight Brazilian patients manifest moderate to severe anxiety regarding dental treatment. In this sample, the degree of anxiety was higher among females (p=0.007), over 20 years of age (p=0.006), without access to the Internet and/or newspapers (p=0.016), with a low frequency of oral hygiene (p=0.001), for whom the reason for the dental appointment was curative treatment, pain or another problem rather than a check up (p=0.047) and those suffering from toothache (p<0.001). Fear and anxiety regarding dental treatment indeed exist in the Brazilian population and the findings of this study suggest that, besides the lack of economic resources, negligence with respect to oral health, gender and age may increase the degree of anxiety.
