Comparative study of the healing process when using Vicryl®, Vicryl Rapid®, Vicryl Plus®, and Monocryl® sutures in the rat dermal tissue

Introduction: Various types of sutures are available in the market with different constitutions. However, there is a lack of research to assess and quantify the behavior of these materials. Resources and materials: This study comes benchmark wires polyglactin 910 (Vicryl ®), irradiated polyglactin 910 (Vicryl Rapid ®), polyglactin 910 treated with triclosan (Vicryl Plus ®), and poliglecaprone 25 (Monocryl ®). For this, we used 40 rats that were divided into two groups, underwent two skin incisions longitudinal 2-cm long. In Group A, simple interrupted sutures using irradiated polyglactin 910 on the right and left side of polyglactin 910, and in group B, polyglactin 910 with triclosan on the right and the left poliglecaprone 25 were made. At 2, 7, 14, and 28 days after surgery, the ten animals were killed per period, and the samples were processed for histomorphologic and histometric analysis. Conclusions: The results demonstrated that the wire poliglecaprone 25 showed better biological response, with less inflammatory infiltrates and rapid organization of connective tissue. © 2012 Springer-Verlag Berlin Heidelberg.

Effect of dietary sodium restriction on body water, blood pressure, and inflammation in hemodialysis patients: a prospective randomized controlled study

Purpose: Accumulating evidence suggests an association between body volume overload and inflammation in chronic kidney diseases. The purpose of this study was to evaluate the effect of dietary sodium reduction in body fluid volume, blood pressure (BP), and inflammatory state in hemodialysis (HD) patients. Methods: In this prospective controlled study, adult patients on HD for at least 90 days and those with C-reactive protein (CRP) levels ≥0.7 mg/dl were randomly allocated into two groups: group A, which included 21 patients treated with 2 g of sodium restriction on their habitual diet; and group B, which included 18 controls. Clinical, inflammatory, biochemical, hematological, and nutritional markers were assessed at baseline and after 8 and 16 weeks. Results: Baseline characteristics were not significantly different between the groups. Group A showed a significant reduction in serum concentrations of CRP, tumor necrosis factor-α, and interleukin-6 during the study period, while BP and extracellular water (ECW) did not change. In group B, there were no changes in serum concentrations of inflammatory markers, BP, and ECW. Conclusions: Dietary sodium restriction is associated with the attenuation of the inflammatory state, without changes in BP and ECW, suggesting inhibition of a salt-induced inflammatory response. © 2013 Springer Science+Business Media Dordrecht.

Effect of dialysate sodium reduction on body water volume, blood pressure, and inflammatory markers in hemodialysis patients - A prospective randomized controlled study

Accumulating evidence suggests an association between body volume overload and inflammation in chronic kidney diseases. The purpose of this study was to evaluate the effect of dialysate sodium concentration reduction on extracellular water volume, blood pressure (BP), and inflammatory state in hemodialysis (HD) patients. In this prospective controlled study, adult patients on HD for at least 90 days and those with C-reactive protein (CRP) levels ≥ 0.7 mg/dL were randomly allocated into two groups: group A, which included 29 patients treated with reduction of dialysate sodium concentration from 138 to 135 mEq/L; and group B, which included 23 HD patients not receiving dialysate sodium reduction (controls). Of these, 20 patients in group A and 18 in group B completed the protocol study. Inflammatory, biochemical, hematological, and nutritional markers were assessed at baseline and after 8 and 16 weeks. Baseline characteristics were not significantly different between the two groups. Group A showed a significant reduction in serum concentrations of tumor necrosis factor-α, and interleukin-6 over the study period, while the BP and extracellular water (ECW) did not change. In Group B, there were no changes in serum concentrations of inflammatory markers, BP, and ECW. Dialysate sodium reduction is associated with attenuation of the inflammatory state, without changes in the BP and ECW, suggesting inhibition of a salt-induced inflammatory response.

Comparison of methods in oral health education from the perspective of adolescents.

To investigate whether teenagers' knowledge about oral health is influenced by educational methods and to verify the most effective method according to their perception. The study was performed in Araçatuba, São Paulo State, Brazil, with 127 teenagers from a vocational school. It was realised in 3 steps: 1. An evaluation of knowledge about oral health using a self-applied questionnaire. 2. An application of educational methods, where the students were divided into two groups (A and B). Group A participated in three educational activities that involved lectures, individual demonstration, and participatory activity. Group B was divided into three subgroups (B1, B2, B3) and each of them participated in only one of the methods. 3. The acquired knowledge was evaluated. Group A created a focus group to give their opinion about strategies. With regards to knowledge after the application of the different methods in all groups, there was a statistically significant difference concerning periodontitis, gingivitis and herpes. In group A, after the three activities, and in group B2 after the individual demonstration, an association was found between 'healthy teeth' and 'general health' (P = 0.004 and P = 0.022, respectively). After the individual demonstration, an association was shown between variables of acquired knowledge about 'harmful diet' and 'dental caries' (P = 0.002) as well as 'good diet' and 'prevention of oral diseases' (P = 0.032). The favourite method was individual demonstration, due to the contact with educational materials, followed by participatory activity because it encouraged learning in a more dynamic way. Educational methods influenced knowledge about oral health, with individual demonstration proving to be the most effective method for acquiring knowledge. In the adolescents' view, the participatory activity was the preferred method.

Cloreto de sódio a 0,9%, adicionado ou não de dexametasona, intrapleural, na prevenção de aderências pulmonares após toracotomia intercostal em cães

Pulmonary adhesions in dogs are a common sequel after surgical intervention, undermining any interventions. This study aimed to determine in dogs, the efficacy of sodium chloride solution 0.9% with or without dexamethasone in order to prevent adhesions after intercostal thoracotomy. Fifteen dogs were separated into three groups of five animals, A, B and C and underwent thoracotomy in the fifth left intercostal space. Three other dogs were submitted to a previous study. In the dogs of Group A it was performed only a thoracotomy and thoracorraphy; in group B, it was performed a thoracotomy, thoracorraphy and injection into the pleural cavity of isotonic sodium chloride (10ml) and dexamethasone (1mg kg-1). In the dogs of the group C, it was performed the thoracotomy thoracorraphy and injected isotonic sodium chloride (10ml kg-1) into the pleural cavity. After 15 days of thoracotomy, it was performed transdiaphragmatic thoracocospy to determine the presence and score of adhesions between the lung and chest wall. The results demonstrated the presence of adhesions in the majority of group A and reduced or no adhesions in the other groups. For statistical evaluation, it was pplied the chi-square test with significance level of 5% (P≤0.05). The sodium chloride solution 0.9% with or without dexamethasone in the pleural space prevented or reduced lung adhesions after intercostal thoracotomy.
