Perception of the informed consent form by participants in clinical trials

To understand the perception of the participants in controlled clinical trials (CCTs) about the informed consent and describe the meaning of their participation in the research. Qualitative study using the focus group technique. The sample was composed of 19 patients who participated in clinical trials about hypertension and coronary disease in a specialized cardiologic hospital located in the city of Sao Paulo. The methodological framework used was the content analysis. Some of the participants were aware of the real objective of these studies while others had misperceptions. The reading of the informed consent is not always done and, when it is done, the patient does not understand it. The lack of understanding about the term ''placebo'' was mentioned by some participants. The motivation to participate was the personal benefit. This study shows that obtaining the informed consent in CCTs is complex and that there is the need to adapt the structure and application of this document, in order to protect the participants and improve the quality of clinical trials performed in the country.

Speech-language therapy for treatment of dysphagia and dysphonia in systemic granulomatous diseases: granulomatous diseases: dysphagia and dysphonia treatments

The granulomatous lesions are frequently founded in infectious diseases and can involve the larynx and pharynx and can cause varying degrees of dysphonia and dysphagia. There is still no systematic review that analyzes effectiveness of speech therapy in systemic granulomatous diseases. Research strategy: A systematic review was performed according to Cochrane guideline considering the inclusion of RCTs and quasi-RCTs about the effectiveness of speech-language therapy to treat dysphagia and dysphonia symptoms in systemic granulomatous diseases of the larynx and pharynx. Selection criteria: The outcome planned to be measured in this review were: swallowing impairment, frequency of chest infections and voice and swallowing symptoms. Data analysis: We identified 1,140 citations from all electronic databases. After an initial shift we only selected 9 titles to be retrieved in full-text. After full reading, there was no RCT found in this review and therefore, we only described the existing 2 case series studies. Results: There were no randomized controlled trials found in the literature. Therefore, two studies were selected to be included only for narratively analysis as they were case series. Conclusion: There is no evidence from high quality studies about the effectiveness of speech-language therapy in patients with granulomatous diseases of the larynx and pharynx. The investigators could rely in the outcomes suggested in this review to design their own clinical trials.

Acupuntura em disfunção temporomandibular: relato de caso clínico

A técnica milenar da Acupuntura vem sendo empregada na Odontologia e obtendo bons resultados em diversas situações. Analgesia, relaxamento muscular e inflamação vêm sendo controlados, demonstrando assim conexão entre Acupuntura e redução de certas sintomatologias. As reações locais e à distância necessitam de correto posicionamento das agulhas assim como integridade do sistema nervoso, e são decorrentes da liberação de neurotransmissores (noradrenalina, acetilcolina, serotoninas e dopamina). Dentro da Odontologia, podemos nos utilizar dos seus efeitos no pré e pós operatório, em xerostomia, cefaléias, trismos, disfunção de ATM por estresse, parestesias, paresias, ansiedade, entre outras condições. Nos casos de disfunção de Articulação Temporomandibular por hiperatividade muscular, podemos utilizar a Acupuntura ao invés de relaxante muscular e antiinflamatório. Nesse trabalho, apresentaremos um caso clínico (paciente MCH, 23 anos, gênero feminino), a qual apresentava crises de dor de cabeça (região temporal), fazendo uso constante de medicação analgésica e antiinflamatória, o diagnóstico estabelecido foi Dor Muscular Local associado à hiperatividade muscular. Através do uso da Acupuntura, após aplicações semanais por 3 meses, houve remissão da dor por completo.

O tratamento com implantes dentários para pacientes com hiv é uma realidade?

Patients infected with HIV can present several complications related to oral health. Today, the reduction of morbidity and mortality is evidenttreatment with antiviral enhances the quality of life of patients. The increase in comfort, stability, function and improving quality of life have led these patients to seek treatment with osseointegrated implants. This study aimed to discuss, based on the literature, the rehabilitation treatment with osseointegrated implants in patients HIV positive. For this we carried out a literature review including the subject in the databases: PubMed, Cochrane, ISI Dentistry and Oral Science in the last 20 years. The issue was addressed for the first time in 1998, describing a clinical case, the patient had successful rehabilitation with osseointegrated implants. However, the literature states that the indications must be carefully analyzed (2007), since there are few prospective controlled studies. There is doubt as to the use of dental implant therapy in patients with HIV-positive, and the complications are related to the patient’s systemic condition. It is essential to understand the clinical manifestations and complications of the disease before the implant therapy. It is observed that the dental implant therapy in patients with HIV positive is a predictable treatment option, it´s need an adequate control of oral and systemic conditions, and studies with larger sample, longer follow-up and randomized studies are important for evaluating the success therapy.

O tratamento da apneia obstrutiva do sono e a utilização de implantes osseointegráveis: revisão da literatura

The obstructive sleep apnea syndrome affects millions of people around the world. The mandibular repositioning devices have been indicated in cases of mild/moderate syndrome; however in edentulous patients its use is deficient since there is no retention. Therefore the objective of this study was to conduct a review on the use of this treatment method combined to osseointegrated implants. A search on the theme: Dental implant and sleep apnea syndromewas performed in the Medline/PubMed, ISI, Cochrane, Dentistry Oral Science, Clinical Trials, Controlled Trials, and Bireme-BvS, databases, and 22 articles were found. After anevaluation 2 studies were selected and the review was complemented with an analysis of randomized controlled trials in the previous seven bases using the key-words: Sleep apnea syndrome, Oral appliance and Randomized controlled trial. The search returned 37 articles, and after they were submitted to inclusion criteria 17 studies were selected. There are a small number of studies presenting the use of dental implants as a mean to assist the stabilization of the mandibular repositioning appliances; those that are available are case reports that focusing on the effectiveness of the technique. Studies examining the effect these appliances in dentate patients indicate improvement in the levels of apnea and snoring. The use of mandibular repositioning appliances in dentate patients is an effective technique in treatment of patients with obstructive sleep apnea syndrome mild/moderate. Randomized controlled trialsare required in order to enable an analysis of the use of mandibular repositioning devices with the aid of dental implants .

Regeneração óssea guiada em implantodontia: relato de caso

Objective: The use of methods for tissue regeneration has been widely applied in Implantology, in clinical situations with disabilities or anatomical limitations that prevent the placement of osseointegrated dental implants. The evolution of the development of biomaterials revolutionized this therapeutic modality, facilitating the resolution of clinical cases with tissue deficiencies. Thus, this study aimed to describe a clinical case approaching the methods, techniques, and materials used in guided bone regeneration applied to Implantology. Case report: A clinical case of a patient who received a Morse taper dental implant (region 15) is described. The use of biomaterial and membrane on the buccal wall of the socket was required. After the osseointegration period, a reopening surgery was performed, and an immediate provisional implant was produced. After 2 months of follow-up, the final prosthesis was made involving other adjacent elements. Final considerations: The guided bone regeneration technique employed showed satisfactory performance. The patient was positive regarding esthetics and function. However, more controlled studies with longer follow-up period are needed for analyses of predictability

Terapéutica alternativa asociada al bruxismo: revisión de literatura

The aim of this study was to review the literature in order to discuss the main and the most effective therapeutic activities to control the nocturnal bruxism. To identify the studies included in this review, it was conducted a detailed and advanced search strategy in the PubMed and Medline databases. It was used as KEY WORDS: bruxism, therapeutics and drug therapy. Inclusion criteria were: case reports, randomized controlled trials, in vitro studies, literature reviews and systematic reviews with or without meta-analysis of the past 10 years that addressed the theme. Exclusion criteria were: articles without abstract, animal studies, articles whose first language was not English and articles from journals that do not belong to the dentario field. From a total of 83 articles, after an analysis according to the inclusion and exclusion criteria, 33 articles were selected. Despite the fact that there is a small number of prospective clinical studies with high degree of reliability and most studies that evaluated the alternative treatments effectiveness are isolated case reports, the current literature shows that the use of botulinum toxin has been shown to be effective in the control of nocturnal bruxism. On the other hand, important aspects such as transitory effect, safe dosage and application technique are still little discussed, then, further studies are needed to have these doubts clarified.

Relation between bruxism and dental implants

OBJECTIVE: The aim of this study was to gather information and discuss the predictability of implant-supported prostheses in patients with bruxism by performing a literature review. METHODS: In order to select the studies included in this review, a detailed search was performed in PubMed and Medline databases, using the following key words: bruxism, dental implants, implant supported prosthesis, and dental restoration failure. Items that were included are: case reports, randomized controlled trials, in vitro studies, literature and systematic reviews, with or without meta-analysis, of the last 20 years that addressed the theme. Articles without abstracts, animal studies, articles in languages other than English and articles from journals unrelated to the dental field were excluded. RESULTS: after analysis according to inclusion and exclusion criteria, 28 articles were selected from a total of 54. It is known from the array of scientific articles which have assessed, either through retrospective, prospective or experimental studies, that the biomechanical and biological impact of bruxism on implant-supported prostheses is small, and that the literature has contributed little to exemplify the prosthetic limits of safety for the specialist from a clinical point of view. CONCLUSION: Although there is still no general consensus on this matter, most of the literature review articles do provide clinical guidelines that contribute to implant supported prostheses longevity and stability in patients with bruxism.

Reações alérgicas aos implantes osseointegráveis de titânio: uma revisão de literatura

Titanium dental implants have been common practice in the dental office, which can increases the number of allergic reactions to this material. Objectives: to alert dental surgeons and specialists of this possible phenomenon through a literature review. Material and methods: an electronic search at PubMed was performed with the keywords “dental implants”, “titanium”, and “allergy” from January 1990 to May 2013. Only articles published in the English language were included. Letters to editor were excluded. Results: from the 22 initially retrieved articles, only 7 were included, being 4 clinical case reports and 3 experimental studies. For clinical cases, the reactions included edema, erythema, exfoliative cheilitis, and eczema. Regarding experimental studies, skin rash and dermatitis were reported. A patch test was not used in two clinical reports. Only one study used histological analysis to attest the lack of allergic reactions. Conclusion: within the limits of the available literature, allergic reactions to titanium dental implants are extremely rare and seem to be related to the female gender. More controlled clinical studies are necessary to elucidate this question.
