Objective: Undocumented migrants in Europe face multiple barriers in access to oral health care. This study aimed to explore the accessibility of a voluntary dental network providing dental treatments to undocumented migrants in the Netherlands, from the perspectives of patients, dentists and staff members of nongovernmental organizations involved.

Methods: This qualitative study used semi-structured interviews (n = 21) with undocumented migrants (n = 12), dentists (n = 7) and staff members of nongovernmental organizations (n = 2) during the implementation of a voluntary dental network.

Aims: To identify potential predictors of types of treatment indicated for patients with temporomandibular disorders (TMD) and to develop, validate, and calibrate a prediction model for type of treatment.

Methods: The derivation cohort at baseline was comprised of 356 adult patients with TMD. Patient and disease characteristics were recorded at baseline as potential predictors.

Rationale, Aims And Objectives: Most of the clinical guidelines in low-resource countries are adaptations from preexisting international guidelines. This adaptation can be problematic when those international guidelines are not based on current evidence or original evidence-based international guidelines are not followed. This study aims to evaluate the quality of an Indonesian type 2 diabetes mellitus guideline adapted from selected international guidelines.

Background: The association between periodontitis and atherosclerotic cardiovascular diseases (ACVD) has been established in some modestly sized studies (<10 000). Rarely, however, periodontitis has been studied directly; often tooth loss or self-reported periodontitis has been used as a proxy measure for periodontitis. Our aim is to investigate the adjusted association between periodontitis and ACVD among all individuals registered in a large dental school in the Netherlands (Academic Centre for Dentistry Amsterdam (ACTA)).

Background: Education in evidence-based medicine (EBM) is an important part of the postgraduate training of GPs. Evaluation of its effect on EBM behaviour in daily clinical practice is difficult and instruments are scarce. Working in accordance with guidelines is considered as one of the key indicators of EBM behaviour.

Background: Otitis media with effusion (OME) is characterised by an accumulation of fluid in the middle ear behind an intact tympanic membrane, without the symptoms or signs of acute infection. Since most cases of OME will resolve spontaneously, only children with persistent middle ear effusion and associated hearing loss potentially require treatment. Previous Cochrane reviews have focused on the effectiveness of ventilation tube insertion, adenoidectomy, nasal autoinflation, antihistamines, decongestants and corticosteroids in OME.

The effects of propranolol in the treatment of anxiety disorders have not been systematically evaluated previously. The aim was to conduct a systematic review and meta-analysis of randomised controlled trials, addressing the efficacy of oral propranolol versus placebo or other medication as a treatment for alleviating either state or trait anxiety in patients suffering from anxiety disorders. Eight studies met the inclusion criteria.

Objectives: To design and validate a practical questionnaire for clinicians, to identify barriers and facilitators for evidence-based practice (EBP), that is, the use of research evidence in patient care. The inventory is ultimately intended for departments to assess local conditions for EBP, to aim and evaluate efforts at improving or maximizing EBP.

Study Design And Setting: We derived candidate items from existing EBP scales, psychology, and behavioral economics.

Background: Acute otorrhea is a common problem in children with tympanostomy tubes. We recently demonstrated that treatment with antibiotic-glucocorticoid eardrops is clinically superior to oral antibiotics and initial observation. The aim of this study was to assess the cost-effectiveness of these three common treatment strategies for this condition.

Objectives: To evaluate the quality of reporting of the risk of bias of the Indonesian medical research.

Methods: Publications from PubMed and non-PubMed indexed Indonesian medical journals between January 2008 to December 2010 were assessed for risk of bias based on criterion combination from Hedges-criteria and the Oxford Center for Evidence-Based Medicine. We assessed whether the publications addressed the risk of bias adequately (quality of reporting) and whether the risk of bias criterion was fulfilled (quality of methods).

Background And Objective: Current resection modalities for oral squamous cell carcinomas (OSCC) vary from cold steel over CO2 laser to monopolar electro-surgery (MO). We compared thulium laser (TL) as a new modality with MO with regards to pathological assessment.

Study Design/materials And Methods: Forty-two patients who were treated for OSCC by either TL or MO were included.

Background: The outcome measures most frequently used in studies on the effectiveness of migraine treatment are whether the patient is free of pain, nausea, and free of photophobia/phonophobia within two hours. However, no patient-centred outcome measures are available. Therefore, we performed an online Delphi procedure to compile a list of outcome measures deemed most important to migraine patients.

Background: Despite more than a century of dedicated research, the etiology and pathogenesis of adolescent idiopathic scoliosis (AIS) remain unclear. By definition, 'idiopathic' implies an unknown cause. Nevertheless, many abnormalities concomitant to AIS have been described, often with the suggestion that these abnormalities are related to etio-pathogenesis.

Background: To assess the degree of awareness, agreement, adoption and adherence of physicians in Indonesia to type 2 diabetes mellitus guidelines, and their association with characteristics of the responders.

Methods: Questionnaire survey among General Practitioners (GPs) attending the Indonesian Association of Family Practitioners annual conference in November 2012. The proportion of GPs who were aware of, agreed with, adopted and adhered to the seven recommendations in the guidelines (screening for diabetes, diagnosis, lifestyle modification, use of sulfonylurea, target blood glucose, target blood pressure and use of statin) were calculated in the total number of responders.

Background: Recent guidance for the management of acute otorrhea in children with tympanostomy tubes is based on limited evidence from trials comparing oral antibiotic agents with topical antibiotics.

Methods: In this open-label, pragmatic trial, we randomly assigned 230 children, 1 to 10 years of age, who had acute tympanostomy-tube otorrhea to receive hydrocortisone-bacitracin-colistin eardrops (76 children) or oral amoxicillin-clavulanate suspension (77) or to undergo initial observation (77). The primary outcome was the presence of otorrhea, as assessed otoscopically, 2 weeks after study-group assignment.

Background Context: As in other fields of medicine, there is an increasing interest among orthopedic surgeons to measure health-related quality of life in adolescent idiopathic scoliosis patients and to evaluate the burden of disease and the effectiveness of different treatment strategies. The development of the revised Scoliosis Research Society 22-item patient questionnaire (SRS-22r) enabled a comprehensive evaluation of health-related quality of life of these patients. Over the years, the SRS-22r gained wide acceptance and has been used in several different countries, languages, and cultures.
