Foreign Body Ingestion During Dental Implant Procedures

Two cases of swallowing of foreign material related to dental implants during dental practice are described. A conservative approach by clinical-radiographic follow-up was performed in both cases; however, one of the patients required colonoscopy under general anesthesia for the removal of the impacted foreign body from the intestinal region. These complications not only have associated economic cost but also carry the risk of malpractice litigation against the professional; thus, the surgeon was responsible for all the costs of hospital and surgery management of this case. Details of the clinical signs, radiographic examinations, type of treatment, and follow-up are presented.

IINTERNATIONAL STRATEGY FOR AN EMERGING MULTINATIONAL IN BRAZIL: THE CASE OF JBS

The focus of this study is on questioning whether the traditional theories of internationalization are adequate to explain the international expansion of multinationals from emerging countries. Looking forward on this issue, we investigate the internationalization strategies adopted by JBS, a Brazilian multinational of the beef industry. The results show that the company adopted two of the five generic strategies specific to the context of emerging countries suggested by Ramamurti and Singh (2009): global consolidator and vertical integrator. Moreover, when analyzing the internationalization of the company under study, the speed of the process is highlighted when compared to traditional multinationals. It is concluded that the main mode of entry that allowed the international expansion was the acquisition and that this strategy has advantages to the company, such as access to strategic resources and rapid growth, possibly overcoming the liability of foreignness, the opportunity to compete globally and the diversification of segments that generate synergies to the company's activities.

Concurrent crack and powder cocaine users from Sao Paulo: Do they represent a different group?

Abstract Background Cocaine abuse is a serious and socially damaging illegal drug problem. Different routes of administration are associated with a specific progression of use, different degrees of abuse liability, propensity for dependence and treatment response. There have been relatively few studies comparing different cocaine users groups and no studies into the characterization of the group of individuals reporting concurrent use of powder cocaine and crack cocaine. Methods Six hundred and ninety-nine cocaine users were assessed during the period August 1997 to October 1998 in one outpatient and six inpatient clinics located in the São Paulo, Brazil. Patients were interviewed using a structured questionnaire schedule in Portuguese, designed specifically for the Brazilian population. The statistical analyses were performed using either ANOVA or a chi-squared test and focusing on their preferred form of use/route of administration and other variables. Results For 83% of the variables tested in this study, the Dual Users subgroup (using both powder and crack cocaine) demonstrated statistical differences from the single drug user subgroups. Those differences include the initiation of cocaine, the abuse of other illicit drugs, and rates of criminal history. Conclusion These data suggest cocaine-dependent individuals who report use of both powder and crack cocaine are an at least partially, distinct subgroup. However, further studies will be necessary to confirm this and to determine if they also show a different treatment response.

At the frontiers of surgery: review

The complete surgical removal of disease is a desirable outcome particularly in oncology. Unfortunately much disease is microscopic and difficult to detect causing a liability to recurrence and worsened overall prognosis with attendant costs in terms of morbidity and mortality. It is hoped that by advances in optical diagnostic technology we could better define our surgical margin and so increase the rate of truly negative margins on the one hand and on the other hand to take out only the necessary amount of tissue and leave more unaffected non-diseased areas so preserving function of vital structures. The task has not been easy but progress is being made as exemplified by the presentations at the 2nd Scientific Meeting of the Head and Neck Optical Diagnostics Society (HNODS) in San Francisco in January 2010. We review the salient advances in the field and propose further directions of investigation.

Estratégia internacional de uma multinacional emergente brasileira: o caso JBS

Este estudo preocupa-se em questionar se as teorias tradicionais de internacionalização são adequadas para explicar a expansão internacional das multinacionais de países emergentes. Procurando avançar nessa questão, investigam-se as estratégias de internacionalização adotadas pela JBS, multinacional brasileira do setor frigorífico. Os resultados evidenciam que a empresa adotou duas das cinco estratégias genéricas específicas ao contexto de países emergentes sugeridas por Ramamurti e Singh (2009): consolidador global e integrador vertical. Além disso, ao analisar a internacionalização da empresa em estudo, chama atenção a velocidade do processo, em comparação às multinacionais tradicionais. Conclui-se que o principal modo de entrada que possibilitou a expansão internacional foi a aquisição e que essa trouxe vantagens à empresa, como o acesso a recursos estratégicos, o crescimento rápido, a possível superação da liability of foreignness, a oportunidade para competir globalmente e a diversificação dos segmentos de atuação que geram sinergias às atividades da empresa.

A aplicação do Código de Defesa do Consumidor às ações judiciais por alegado erro médico

A presente pesquisa tem como objetivo analisar a responsabilidade do médico dentro do contexto doutrinário e jurisprudencial da atualidade e demonstrar, a partir da análise de ações judiciais por alegado erro médico, propostas perante o Poder Judiciário, que os direitos atribuídos ao consumidor pelo Código de Defesa do Consumidor, bem como as prerrogativas de facilitação do acesso ao Judiciário atualmente são aplicados pelos profissionais do Direito ao exercício da atividade médica de forma generalizada, ou seja, tanto em relação às sociedades empresárias – hospitais, clínicas e planos de saúde, quanto aos profissionais liberais, sem considerar que o § 4º do art. 14 do Código de Defesa do Consumidor, ao estabelecer como requisito para a responsabilidade do profissional liberal a comprovação de culpa (imprudência, negligência e imperícia), determina, a contrario sensu, a aplicação das normas do Código Civil, de forma que, também as prerrogativas de facilitação de acesso ao Judiciário, exclusivas da legislação de consumo, não poderiam ser aplicadas ao exercício da atividade pelo profissional liberal.

A Sib-Pair analysis of impulsivity in bipolar disorder type I

OBJECTIVE: The aim of this study was to compare impulsivity among patients with bipolar disorder, their siblings, and healthy controls in order to examine whether impulsivity in bipolar disorder is related to genetic liability for the illness. METHODS: Using the Barratt Impulsiveness Scale, we assessed 204 subjects: 67 euthymic outpatients with bipolar disorder type I, 67 siblings without bipolar disorder, and 70 healthy controls. RESULTS: Impulsivity scores were higher among patients with bipolar disorder than among healthy controls. Siblings showed higher motor impulsivity scores than did healthy controls. CONCLUSIONS: Our results suggest that motor impulsivity may be a vulnerability marker for bipolar disorder. Our data may contribute to further improve preventive strategies in subjects at high risk for bipolar disorder.
