New option for anterior traction of the face by using a cervical collar

This case required anteroposterior traction of the maxilla. Once none of the traditional methods could be used because of the lack of support in the chin and in the frontal region. Thus, we opted to use a cervical collar.

Molecular typing of bacterial strains isolated from the Clinics of Surgery and Face Traumatology at Ribeirão Preto University

The number of infectious illnesses and cross infection is spreading drastically among the professionals of the dentistry area. Controlling infections in dental offices is one of the greatest challenges for dentists and researchers of this area. In practice, contacts between professionals and infected patients are relatively common. The transmission of infectious illnesses from the health professionals to their patients is also possible, either by direct contact or due to lack of cares in relation to biosafety, increasing the cycle of cross infection. Molecular typing is necessary since these methods are an important tool to investigate the epidemiology of bacterial infections. Moreover, they are important for supplying information and precedents through the analysis of the infectious agents eletrophoretic profile. The aim of the present work was to analyze by molecular typing the genomic profile of aerobic bacteria isolated from the Clinics of Surgery and Face Traumatology, Ribeirão Preto University, through the technique of Random Amplified Polymorphic DNA (RAPD) and grouped based on similarity coefficients. Of two carried out collections, 55 strains were isolates belonging to the following groups: 12 Staphylococcus aureus; 13 Klebsiella oxytoca; 7 Klebsiella pneumoniae; 8 Pseudomonas aeruginosa; 5 Hafnia alvei; 5 Proteus vulgaris; 4 Escherichia coli; and 1 Proteus mirabilis. The adopted molecular typing strategy allowed the determination of the persistence of definitive strains at the collection environment, besides the identification of strains proceeding from the hands and gloves of the surgeon dentists, which could have been found in distant places as sinks and reflectors.

Azul de metileno no tratamento da síndrome vasoplégica em cirurgia cardíaca. quinze anos de perguntas, respostas, dúvidas e certezas

Objective: There is strong evidence that methylene blue (MB), an inhibitor of guanylate cyclase, is an excellent therapeutic option for vasoplegic syndrome (VS) treatment in heart surgery. The aim of this article is to review the MB's therapeutic function in the vasoplegic syndrome treatment. Methods: Fifteen years of literature review. Results: 1) Heparin and ACE inhibitors are risk factors; 2) In the recommended doses it is safe (the lethal dose is 40 mg/ kg); 3) The use of MB does not cause endothelial dysfunction; 4) The MB effect appears in cases of nitric oxide (NO) up-regulation; 5) MB is not a vasoconstrictor, by blocking of the GMPc system it releases the AMPc system, facilitating the norepinephrine vasoconstrictor effect; 6) The most used dosage is 2 mg/kg as IV bolus followed by the same continuous infusion because plasmatic concentrations strongly decays in the first 40 minutes; 7) There is a possible window of opportunity for the MB's effectiveness. Conclusions: Although there are no definitive multicentric studies, the MB used to treat heart surgery VS, at the present time, is the best, safest and cheapest option, being a Brazilian contribution for the heart surgery.

This paper presents a novel, fast and accurate appearance-based method for infrared face recognition. By introducing the Optimum-Path Forest classifier, our objective is to get good recognition rates and effectively reduce the computational effort. The feature extraction procedure is carried out by PCA, and the results are compared to two other well known supervised learning classifiers; Artificial Neural Networks and Support Vector Machines. The achieved performance asserts the promise of the proposed framework. ©2009 IEEE.

Estudo comparativo entre o tratamento radioterápico com elétrons e betaterapia, após cirurgia de queloides

Introduction: The surgery of keloids as an individual therapy with high rates of recurrence needs adjuvant therapies as complement. Recent keloids are rich in fibroblasts, which are highly radiosensitive and what explains the good results of percutaneous radiotherapy after surgery. Objective: To compare the beta-therapy results with electron-beam technique in newly operated keloids. Material and Methods: a prospective, comparative and randomized study was outlined including patients in the immediate postoperative period of surgical excision of keloids. Divided in G1 and G2 groups respectively, they received treatment with Sr90 (beta-therapy)plates or with electrons from the linear accelerator. The monitoring lasted 10 years. The results were performed using the information from patients, photograph parameters, observation and measurement of injuries, according to the criteria: Unchanged, Regular, Good and Excellent. Results: There were 26 patients, 13 in each group. In G1, 54% presented regular and unchanged improvement criteria and 46% had good or excellent criteria. In G2, the results were respectively 23% and 77%. Conclusion: The irradiation with electron-beam is better than beta-teraphy for the treatment of keloids surgery, due to the distribution in the tissue. No radio-induced tumors were observed.

Evolução da perda de peso entre indivíduos da fila de espera para a cirurgia bariátrica em um ambulatório multidisciplinar de atenção secundária à saúde

Objective: The objective of this study is to characterize the assistance and analyze patient's adherence to nutritional follow-up while in the waiting line for bariatric surgery in a multidisciplinary, secondary healthcare outpatient clinic. Methods: This retrospective study was based on the nutritional records of 59 patients subjected to bariatric surgery at the Hospital das Clinics de Botucatu, from 2001 to 2008. The population studied was distributed into 8 groups and analyzed according to follow-up duration. The analysis took into account the evolution of body weight and the number of follow-up visits in a given period. The Kruskal-Wallis test was used to compare data between groups while Spearman's coefficient was used to test correlations. Results: Among the 59 studied patients, 42 (71.2%) returned to the clinic at least once in six months. Of these, 67.8% lost weight while in the waiting line and 27.1% of them lost more than 10% of their body weight. The greatest weight losses in the preoperative period were found in the groups that had more than six months of nutrition follow-up. There was a mean delay of three months between return visits, which could have contributed to the low adherence to follow-up. Conclusion: The patients in the waiting line for surgery analyzed in this study presented low adherence to the long-spaced return visits. The greatest weight losses were observed in groups that had been followed for more than six months. This shows that, to achieve the desired weight loss and an adequate education process before surgery, at least six months of follow-up and regular visits are necessary.

Epidemiologia do Padrão Face Longa em escolares do Ensino Fundamental do município de Bauru - SP

OBJECTIVE: This study aimed to classify and determine the prevalence of individuals with vertical alteration of facial relationships, according to the severity of discrepancy, especially individuals with long face pattern. METHODS: The sample was composed of 5,020 individuals of Brazilian nationality, of both genders, aged 10 years to 16 years and 11 months, attending fundamental schools at the city of Bauru-SP. Examination of facial morphology comprised direct observation of the face in frontal and lateral views, always with the lips at rest, aiming to identify the individuals presenting vertical alteration of facial relationships. After identification, these individuals were scored, according to severity, into three subtypes, namely mild, moderate and severe. The prevalence of individuals with long face pattern considered only the individuals scored as subtypes moderate and severe. RESULTS: There was prevalence of 34.94% of vertical alteration of facial relationships and 14.06% of long face pattern. CONCLUSIONS: The results obtained in this study revealed that the prevalence of vertical alteration of facial relationships and long face pattern was higher than reported in the literature.

Cirurgia micrográfica de Mohs

Mohs Micrographic Surgery is regarded as a very useful technique for the excision of difficult to han- dle skin cancers. The procedure is divided into clearly defined steps: tumor evaluation and marking, tumor exeresis, tissue preparation and mapping, histologic processing and analysis, and closing of the surgical wound. The histologic analysis of all surgical margins leads to higher cure rates and tissue conservation, which make the procedure safer and more reliable.

Análise do risco de ocorrência da monilíase em cacaueiro no Brasil face às mudanças climáticas globais

The aim of this study was to evaluate the potential risk of moniliasis occurrence and the impacts of climate change on this disease in the coming decades, should this pathogen be introduced in Brazil. To this end, climate favorability maps were devised for the occurrence of moniliasis, both for the present and future time. The future scenarios (A2 and B2) focused on the decades of 2020, 2050 and 2080. These scenarios were obtained from six global climate models (GCMs) made available by the third assessment report of Intergovernmental Panel on Climate Change (IPCC). Currently, there are large areas with favorable climate conditions for moniliasis in Brazil, especially in regions at high risk of introduction of that pathogen. Considering the global warming scenarios provided by the IPCC, the potential risk of moniliasis occurrence in Brazil will be reduced. This decrease is predicted for both future scenarios, but will occur more sharply in scenario A2. However, there will still be areas with favorable climate conditions for the development of the disease, particularly in Brazil's main producing regions. Moreover, pathogen and host alike may undergo alterations due to climate change, which will affect the extent of their impacts on this pathosystem.
