RESUMO
The treatment of peri-implantitis is challenging in the clinical practice of implant dentistry. With limited therapeutic options and drug resistance, there is a need for alternative methods, such as photodynamic therapy (PDT), which is a minimally invasive procedure used to treat peri-implantitis. This study evaluated whether the type of photosensitizer used influences the results of inflammatory control, reduction in peri-implant pocket depth, bleeding during probing, and reduction in bone loss in the dental implant region. We registered the study in the PROSPERO (International Prospective Register of Systematic Review) database. We searched three main databases and gray literature in English without date restrictions. In vivo randomized clinical studies involving individuals with peri-implantitis, smokers, patients with diabetes, and healthy controls were included. PDT was used as the primary intervention. Comparators considered mechanical debridement with a reduction in pocket depth as the primary outcome and clinical attachment level, bleeding on probing, gingival index, plaque index, and microbiological analysis as secondary outcomes. After reviewing the eligibility criteria, we included seven articles out of 266. A great variety of photosensitizers were observed, and it was concluded that the selection of the most appropriate type of photosensitizer must consider the patient's characteristics and peri-implantitis conditions. The effectiveness of PDT, its effects on the oral microbiome, and the clinical patterns of peri-implantitis may vary depending on the photosensitizer chosen, which is a crucial factor in personalizing peri-implantitis treatment.
RESUMO
INTRODUCTION: In university hospital settings most prescriptions are written by junior doctors, who are more likely to make prescribing errors than experienced doctors. Prescribing errors can cause serious harm to patients and drug harm differs among low, middle and high-income countries. In Brazil, few studies have investigated the causes of these errors. Our aim was to explore medication prescribing errors in a teaching hospital, their causes, and underlying factors from the perspective of junior doctors. METHOD: Qualitative, descriptive and exploratory study that used a semi-structured individual interview with questions related to the planning and execution of prescriptions. It was conducted with 34 junior doctors who graduated from twelve different universities located in six Brazilian states. The data were analyzed according to the Reason's Accident Causation model. RESULTS: Among the 105 errors reported, medication omission stood out. Most errors resulted from unsafe acts during execution, followed by mistakes and violations. Many errors reached the patients; unsafe acts of rule violations and slips accounted for the majority. Work overload and time pressure were the most frequently reported causes. Difficulties faced by the National Health System and organizational problems were identified as latent conditions. CONCLUSION: The results reaffirm international findings about the severity of prescribing errors and the multifactorial aspect of their causes. Unlike other studies, we found a large number of violations, which, from the interviewees' perspectives, are related to socioeconomic and cultural patterns. The violations were not seen or mentioned by the interviewees as violations, but as difficulties in accomplishing their tasks on time. Knowing these patterns and perspectives is important for implementing strategies to improve the safety of both patients and professionals involved in the medication process. It is suggested that the exploitation culture of junior doctors' work be discouraged and that their training be improved and prioritized.

BACKGROUND: Obesity remains a public health problem worldwide. The high prevalence of this condition in the population raises further concerns, considering that comorbidities are often associated with obesity. Among the comorbidities closely associated with obesity, metabolic syndrome (MS) is particularly important, which potentially increases the risk of manifestation of other disorders, such as the prothrombotic and systemic pro-inflammatory states. METHODS: A randomized, controlled clinical trial was performed involving female patients (n = 32) aged between 18 and 65 years, with a clinical diagnosis of MS, with severe obesity undergoing Roux-en-Y gastric bypass (RYGB). The study design followed the Consolidated Standards of Reporting Trials statement (CONSORT). Lipid profile, blood glucose and adipokines (adiponectin, leptin, and resistin) and (cytokines IL-1ß, IL-6, IL-17, IL-23, and TNF-α) in blood plasma samples were evaluated before and six months after RYGB. RESULTS: Patients undergoing RYGB (BSG) showed a significant improvement from preoperative grade III obesity to postoperative grade I obesity. The results showed that while HDL levels increased, the other parameters showed a significant reduction in their postoperative values when compared not only to the values observed before surgery in the BSG group, but also to the values obtained in the control group (CG). As for systemic inflammatory markers adiponectin, leptin, resistin, IL-1ß, IL-6, IL-17, IL-23 and TNF- α it was observed that the levels of resistin and IL-17 in the second evaluation increased significantly when compared to the levels observed in the first evaluation in the CG. In the BSG group, while the levels of adiponectin increased, the levels of the other markers showed significant reductions in the postoperative period, in relation to the respective preoperative levels. The analysis of Spearman's correlation coefficient showed a significant positive correlation between IL-17 and IL-23 in the preoperative period, significant positive correlations between TNF-α and IL-6, TNF-α and IL-17, IL-6 and IL-17, and IL-17 and IL-23 were observed postoperatively. CONCLUSIONS: According to our results, the reduction of anthropometric measurements induced by RYGB, significantly improves not only the plasma biochemical parameters (lipid profile and glycemia), but also the systemic inflammatory status of severely obese patients with MS. Trials registration NCT02409160.
RESUMO
Obesity is a troubling public health problem as it increases risks of sleep disorders, respiratory complications, systemic arterial hypertension, cardiovascular diseases, type 2 diabetes mellitus, and metabolic syndrome (MetS). As a measure to counteract comorbidities associated with severe obesity, bariatric surgery stands out. This study aimed to investigate the adiponectin/leptin ratio in women with severe obesity with and without MetS who had undergone Roux-en-Y gastric bypass (RYGB) and to characterize the biochemical, glucose, and inflammatory parameters of blood in women with severe obesity before and after RYGB. Were enrolled females with severe obesity undergoing RYGP with MetS (n = 11) and without (n = 39). Anthropometric data and circulating levels of glucose, total cholesterol, high-density lipoprotein (HDL), non-HDL total cholesterol, low-density lipoprotein (LDL), adiponectin, and leptin were assessed before and 6 months after RYGB. Significant reductions in weight, body mass index, and glucose, total cholesterol, LDL, and leptin were observed after surgery, with higher levels of HDL, adiponectin, and adiponectin/leptin ratio being observed after surgery compared to the preoperative values of those. This study demonstrated that weight loss induced by RYGB in patients with severe obesity with or without MetS improved biochemical and systemic inflammatory parameters, particularly the adiponectin/leptin ratio.

OBJECTIVES: Mental problems such as stress, anxiety and depression have been described among medical students and are associated with poor academic and professional performance. It has been speculated that these problems impair students' quality of life (QoL). The authors aimed to assess the health-related QoL (HRQL) of medical students throughout their 6 years of training at a school with a traditional curriculum. METHODS: Of a total of 490 students attending our institution's medical school, 38 were surveyed in February 2006 (incoming Year 1 group, surveyed when students were in the second week of Year 1 classes) and 352 were surveyed in February 2007 (students in Years 1-6). Students self-reported their HRQL and depressive symptoms using the Short-Form Health Survey (SF-36) and the Beck Depression Inventory (BDI). Comparisons were performed according to year in training, presence of depressive symptoms, gender, living arrangements and correlations with family income. RESULTS: The students' ages ranged from 18 to 31 years (median 22.3 years). Students in Years 2, 3, 4 and 6 had lower scores for mental and physical dimensions of HRQL compared with the incoming Year 1 group (P < 0.01), with the largest difference observed for Year 3 students. Students with depressive symptoms had lower scores in all domains of the SF-36 (P < 0.01). Female students had lower HRQL scores than males (P < 0.01). No differences were observed for students living with versus without family and no correlation with family income was found. CONCLUSIONS: Major impairments in HRQL were observed among Year 3 students, students with depressive symptoms and women. Medical schools should institute efforts to ensure that students' HRQL and emotional support are maintained, particularly during critical phases of medical training.

BACKGROUND: Cerebral palsy (CP) patients have motor limitations that can affect functionality and abilities for activities of daily living (ADL). Health related quality of life and health status instruments validated to be applied to these patients do not directly approach the concepts of functionality or ADL. The Child Health Assessment Questionnaire (CHAQ) seems to be a good instrument to approach this dimension, but it was never used for CP patients. The purpose of the study was to verify the psychometric properties of CHAQ applied to children and adolescents with CP. METHODS: Parents or guardians of children and adolescents with CP, aged 5 to 18 years, answered the CHAQ. A healthy group of 314 children and adolescents was recruited during the validation of the CHAQ Brazilian-version. Data quality, reliability and validity were studied. The motor function was evaluated by the Gross Motor Function Measure (GMFM). RESULTS: Ninety-six parents/guardians answered the questionnaire. The age of the patients ranged from 5 to 17.9 years (average: 9.3). The rate of missing data was low (<9.3%). The floor effect was observed in two domains, being higher only in the visual analogue scales (< or = 35.5%). The ceiling effect was significant in all domains and particularly high in patients with quadriplegia (81.8 to 90.9%) and extrapyramidal (45.4 to 91.0%). The Cronbach alpha coefficient ranged from 0.85 to 0.95. The validity was appropriate: for the discriminant validity the correlation of the disability index with the visual analogue scales was not significant; for the convergent validity CHAQ disability index had a strong correlation with the GMFM (0.77); for the divergent validity there was no correlation between GMFM and the pain and overall evaluation scales; for the criterion validity GMFM as well as CHAQ detected differences in the scores among the clinical type of CP (p < 0.01); for the construct validity, the patients' disability index score (mean:2.16; SD:0.72) was higher than the healthy group (mean:0.12; SD:0.23)(p < 0.01). CONCLUSION: CHAQ reliability and validity were adequate to this population. However, further studies are necessary to verify the influence of the ceiling effect on the responsiveness of the instrument.

Currently, there are no specific markers for juvenile idiopathic arthritis (JIA) diagnosis, which is based on clinical symptoms and some blood tests for diseases' exclusion. Aiming to select new epitope-based antigens (mimotopes) that could recognize circulating autoantibodies in most JIA forms, we screened a phage displayed random peptide library against IgG antibodies purified from serum of JIA patients. ELISA assay was carried out to confirm immunoreactivity of selected peptides against sera IgG antibodies from JIA patients, healthy children and patients with other autoimmune diseases. The mimotope PRF+1 fused to phage particles was able to efficiently discriminate JIA patients from controls, and for this reason was chosen to be chemically synthesized for validation in a larger sample size. The synthetic peptide was immobilized onto bioelectrodes' surface for antibody detection by electrochemical analyses through differential pulse voltammetry. The PRF+1 synthetic peptide has efficiently discriminated JIA patients from control groups (p<0.0001) with a very good accuracy (AUC>0.84; sensitivity=61%; specificity=91%). The electrochemical platform proved to be fast, low cost and effective in detecting anti-PRF+1 antibodies from JIA patients compared to healthy controls (p=0.0049). Our study describes a novel and promising epitope-based biomarker for JIA diagnosis that can become a useful tool for screening tests, which was successfully incorporated onto an electrochemical biosensor and could be promptly used in field diagnostics.

Juvenile idiopathic arthritis (JIA) refers to a heterogeneous group of illnesses that have in common the occurrence of chronic joint inflammation in children younger than 16 years of age. The diagnosis is made only on clinical assessment. The identification of antibody markers could improve the early diagnosis, optimizing the clinical management of patients. Type II collagen is one potential autoantigen that has been implicated in the process of arthritis development. The aims of our study were to investigate the occurrence of anti-type II collagen antibodies and also to determine the avidity of the antibody-antigen binding. Ninety-six patients with oligoarticular or polyarticular JIA, 13 patients with ankylosing spondylitis (AS) and 61 healthy controls (HC) were tested for anti-type II collagen antibodies by ELISA and avidity ELISA. Sensitivity and specificity were determined by the receiver operating characteristic (ROC) curve analysis. Forty-two JIA patients (44%) were positive for antibodies against type II collagen. Its detection was significantly higher in JIA patients than in AS patients (p=0.006) and HCs (p<0.0001). Furthermore, anti-type II collagen antibody detection was significantly more frequent in patients with JIA of ≤6 months duration (p=0.0007). Antibodies displaying high avidity to type II collagen were associated with disease activity (p=0.004). This study demonstrates that antibodies against type II collagen are present in the serum of patients with oligoarticular and polyarticular JIA, being its presence more prevalent in patients with early disease. It also demonstrates that JIA patients with active disease present antibodies with high avidity against type II collagen.

OBJECTIVES: Translate, adapt and validate the Patient-Practitioner Orientation Scale (PPOS) for use in Brazil. METHODS: The PPOS was translated to Portuguese using a modified Delphi technique. The final version was applied to 360 participants. Reliability (test-retest and internal consistency) and construct validity (explanatory and confirmatory factor analysis) were assessed. RESULTS: Only two items did not reach pre-established criteria agreement in Delphi technique. In pre-testing, seven items were modified. Internal consistency (Cronbach's alpha=0.605) and test-retest reliability (intraclass correlation coefficient=0.670) were adequate. In explanatory factor analysis, one item did not achieve a loading factor, one item was considered factorially complex and two items were inconsistent with a priori factors. Confirmatory factor analysis provided an acceptable adjustment for the observed variables (χ(2)/df=2.33; GFI=0.91; AGFI=0.89; CFI=0.84; NFI=0.75; NNFI=0.81; RMSEA=0.062 (p=0.016) and SRMR=0.065). CONCLUSIONS: The Brazilian version PPOS (B-PPOS) showed acceptable validity and adequate reliability. PRACTICE IMPLICATIONS: The use of the B-PPOS in national and cross-cultural studies may contribute to the evaluation and monitoring of the attitudes of doctors, medical students and patients toward their professional relationships in research and practice.

GOALS: To evaluate the psychometric properties of the initial Brazilian version of the Child Health Questionnaire(CHQ-PF50) in children and adolescents with cerebral palsy(CP). METHODS: The caregivers of 5- to 18-year-old children and adolescents with CP answered the self-administered CHQ-PF50 questionnaire. Data quality, reliability and validity were studied. The Gross Motor Function Measure was used to assess physical function. RESULTS: Ninety-six caregivers answered the questionnaire. Patient age ranged from 5 to 17.9 years (mean: 9.3 years). Missing data rate was low. Floor effect occurred in 3 scales and was substantial for quadriplegia group (63.6-77.3%). Ceiling effect occurred in 9 scales. Reliability was adequate for all scales except for the general health perception scale (Cronbach alpha coefficient = 0.24). The validity was adequate in general, but the role/social limitations-emotional behavioral scale was not satisfactory for discriminant and divergent validity. CONCLUSION: The initial Brazilian version of the CHQ-PF50 showed, in general, adequate psychometric properties for application in patients with CP. Although floor and ceiling effects are expected in heterogeneous group as a limitation inherent to generic assessment instruments, they must be carefully considered in further studies. The general health perception and role/social limitations-emotional behavioral scale must be further reviewed for this population.

The prevalence and clinical relevance of IgM and IgA RF detected by ELISA were studied in 91 patients with juvenile rheumatoid arthritis (JRA) and 45 healthy children. IgM and IgA RF were detected, respectively, in 33 and 44% of the patients, compared to 6.7 and 15.6% of the healthy children (p = 0.001 and 0.0006, respectively). The frequency of IgM RF was significantly higher in patients with polyarticular (52%) as compared to systemic onset JRA (21%; p = 0.04). Five out of ninety-one patients and none of the control group were IgM RF positive by the latex test. High levels of IgM RF were detected more frequently in patients with active disease (p = 0.01) and positive latex agglutination test (p < 0.001) and had a marginally significant association with severe radiological deformities (p = 0.05). The presence of IgA RF was associated with active disease in polyarticular onset JRA children (p = 0.04). In conclusion, high levels of IgM RF and the detection of IgA RF can be useful in assessing clinical activity in a subset of patients with JRA.

OBJECTIVE: Kawasaki disease is a systemic idiopathic self-limited vasculitis of small and medium-sized vessels. Thirteen cases of sensorineural hearing loss during the evolution of this disease have been described in the literature. We describe a case of an infant with Kawasaki disease who developed sensorineural hearing loss during the acute phase. This case report shows a complication of Kawasaki disease, with few citations in literature, enhancing the importance of careful evaluation of these patients. DESCRIPTION: Nineteen-month-old-boy, formerly healthy, with persistent daily fever seven days before admission, associated with irritability, bilateral nonexudative conjunctivitis and maculopapular erythema on his trunk. There was later development of arthritis on wrists, elbows, knees, and ankles, and swelling associated with desquamation of hands and feet, which prevented him from walking. The diagnosis of Kawasaki disease was established according to the American Heart Associations criteria, and the child was conventionally treated. There was regression of clinical manifestations three days after the beginning of treatment. However, one month after the onset of symptoms, the family noticed an unsatisfactory response to sound stimuli. The evaluation of auditory acuity through BERA (Brainstem Evoked Responses Audiometry) revealed severe bilateral sensorineural hearing loss. COMMENTS: Routine examination of auditory acuity in children with Kawasaki disease may help identify sensorineural hearing loss at an early stage.
RESUMO
OBJECTIVE: To evaluate the inter- and intrareader variability for interpretation of a modified Larsen's radiographic classification system for juvenile rheumatoid arthritis (JRA) focused on osteochondral lesions and a conventional Larsen's classification system, compared to a reference MR scoring system of corresponding images. MATERIALS AND METHODS: Seventy-five radiographs of 60 children with JRA, performed within a short interval of time from the MR examinations, were independently evaluated by three experienced radiologists, three diagnostic imaging residents and three rheumatologists, in two separate sessions, according to the two different classification methods, blinded to the corresponding MR images. RESULTS: The inter- and intrareader concordance rates between the two radiographic classification systems and the MR-related radiographs were respectively poor and poor/moderate. The interobserver range of weighted kappa values for the conventional and the modified Larsen's system respectively was 0.25-0.37 vs 0.19-0.39 for radiologists, 0.25-0.37 vs 0.18-0.30 for residents and 0.19-0.51 vs 0.17-0.29 for rheumatologists. The intrareader rate ranged from 0.17-0.55 for radiologists, 0.2-0.56 for residents, and 0.14-0.59 for rheumatologists. CONCLUSION: Although the proposal of a new radiographic classification system for JRA focused on osteochondral abnormalities sounds promising, the low inter- and intrareader concordance rates with an MR-related radiographic system makes the clinical applicability of such a radiographic system less suitable.

Objetivo: a doença de Kawasaki (DK) é uma vasculite sistêmica idiopática, autolimitada, de pequenos e médios vasos. Foram descritos na literaura treze casos de deficiência auditiva neurossensorial, durante a evolução dessa doença. Descreve-se o caso de um lactente com doença de Kawasaki com evolução, durante a fase aguda, para deficiência auditiva neurossensorial. A descrição do caso justifica-se por ilustrar uma complicação grave da DK, pouco mencionada na literatura, que reforça a recomendação de cautela na avaliação global destes pacientes. Descrição: menino hígido de 1 ano e sete meses de idade apresentou-se com febre diária persistente, iniciada havia sete dias, associada à irritabilidade,conjutivite bilateral não-exsudativa, reitema máculo-papular em tronco. Evoluiu com artrite em punhos, cotovelos, joelhos e tornozelos e edema e descamação de mãos e pés, que impossibilitava a deambulação. O diagnóstico de doença de Kawasaki foi estabelecido de acordo com os critérios da American Heart Association (AHA), e a criança foi tratada de forma convencional. Houve regressão das manifestações clínicas três dias após o inicio do tratamento. Contudo, um mês após o início dos sintomas, os familiares notaram resposta insatisfatória a estímulos sonoros. A avaliação da acuidade auditiva através do BERA (Brainstem Evoked Responses Audiometry - Audiometria de Potenciais Evocados de Tronco Cerebral) disgnosticou perda auditiva neurossensorial bilateral, grau severo a profundo. Comentários: é possível que o exame rotineiro de acuidade auditiva em crianças com doença de Kawasaki possa identificar precocemente a deficiência auditiva neurossensorial

Esse caso ressalta a importância da osteomielite crônica recorrente multifocal para o diagnóstico diferencial das espondilites infecciosas. Menina, nove anos de idade, com história de febre intermitente, artrite em joelhos e tornozelos e dor na coluna torácica lombar havia seis meses. Ao exame físico observaram-se escoliose e limitação importante da flexão da coluna toracolombar. Os exames laboratoriais revelaram discreta leucocitose, elevação das proteínas de fase aguda ePPD não reator. A radiografia simples e a tomografia de coluna evidenciaram redução de altura do corpo vertebral de L1 e do interespaço do disco L3-L4 com ponte óssea entre estes corpos vertebrais e osteocondensação dos platôs vertebrais. A hipótese inicial foi de mal de Pott e a paciente foi tratada com esquema convencional para tuberculose óssea por seis meses. Houve melhora importante da deformidade de coluna, mas persistiram os episódios de dores articulares e edema em joelhos e tornozelos. A radiografia simples de tornozelo esquerdo revelou lesão osteolítica de contorno geográfico com esclerose marginal em região metafisária da tíbia. A biópsia de fragmento ósseo de tíbia mostrou fibrose medular e cultura negativa. Nova tomografia de coluna revelou aumento das dimensões e da densidade das áreas de osteocondensação sem comprometimento de partes moles adjacentes. Esses achados são sugestivos de osteomielite crônica recorrente multifocal. Embora rara, a osteomielite crônica recorrente multifocal é um dos diagnósticos diferenciais das espondilites infecciosas. Seu reconhecimento pode evitar tratamentos antimicrobianos prolongados e desnecessários
