RESUMO

The aim of our study was to compare socio-demographic characteristics of vocal fold nodules, polyps and oedema. The study included patients diagnosed for the first time with vocal fold nodules, polyps and oedema at the Communication Disorders Care Center of Clinic for Otorhinolaryngology and Maxillofacial Surgery in Clinical Center of Serbia, Belgrade. Diagnosis was made on the basis of symptoms, clinical otorhinolaryngological and phoniatric examination and endovideolaryngostroboscopic findings. A self-administered questionnaire was used to collect the following data: socio-demographic status, exposure to occupational noise and air pollution, occupational voice demands, health habits, symptoms of the present voice problems and voice problems in the family. By multivariate logistic regression analyses, nodules and oedema were more frequent in women than men in comparison with polyps (p < 0.001). Patients with nodules and polyps were younger than those with oedema (p < 0.001). Patients with nodules were more frequently lecturers, singers and actors compared with polyp patients (p = 0.006), had occupational voice demands more frequently than patients with oedema (p = 0.037) and were less frequently smokers than patients with polyps (p = 0.043) and those with oedema (p < 0.001). Patients with oedema were more frequently current smokers than patients with nodules and those with polyps (p < 0.001). Hoarseness as the main symptom was more frequent among patients with nodules than among patients with polyps (p = 0.040) and those with oedema (p = 0.001).Voice problems in the family was more frequently reported by oedema patients than by patients with polyps (p = 0.005). These findings are in agreement with majority of previous studies and may be of help in investigations on the aetiology of the disease.

RESUMO

INTRODUCTION: Incidence of children with autism spectrum disorder (ASD) is rising through the years with estimated 1 in 68 in the US in 2014. This incidence is also rising in the population of congenitally deaf children. Favorable outcome after early cochlear implantation is expected due to plasticity and reorganization capacity of brain in infants and toddlers, but outcomes could be significantly modified in children with diagnosed ASD. Current methods of screening for autism have difficulties in establishing diagnosis in children who have both autism and other developmental delays, especially at such an early age. The aim of the study was to assess the development of auditory perception and speech intelligibility in implanted children with profound congenital hearing loss who were diagnosed with ASD comparing to those who were typically developing. MATERIAL AND METHODS: Fourteen children underwent cochlear implantation; four were later diagnosed with ASD and ten were typically developing. All children underwent intensive postoperative speech and hearing therapy. The development of auditory perception and speech intelligibility was assessed using the Categories of Auditory Performance (CAP) and the Speech Intelligibility Rating (SIR) during the 5-years follow-up. RESULTS: In children later diagnosed with ASD, auditory processing developed slowly. Depending on the individual capabilities, by the age of six they could identify environmental sounds or discriminate speech sounds. Speech Intelligibility in children with ASD was at best rated as category 2, with very little or no progress up to the age of six, despite extensive speech and language therapy. Communication skills were strongly affected by a degree of autistic features expression. CONCLUSION: Preoperative psychological assessment in congenitally deaf infants should be expanded by the use of validated instruments for early detection of autism. The possibility of developing ASD should be kept in mind by all professionals involved in programs for cochlear implantation.

RESUMO

BACKGROUND/OBJECTIVES: Some studies document relationships of the incidence of gestational diabetes mellitus (GDM) with individual components of the diet, but studies exploring relationships with patterns of eating are lacking. This observational study aimed to explore a possible relationship between the incidence of GDM and the Mediterranean diet (MedDiet) pattern of eating. SUBJECTS/METHODS: In 10 Mediterranean countries, 1076 consecutive pregnant women underwent a 75-g OGTT at the 24th-32nd week of gestation, interpreted both by the ADA_2010 and the International Association of the Diabetes and Pregnancy Study Groups (IADPSG)_2012 criteria. The dietary habits were assessed by a previously validated questionnaire and a Mediterranean Diet Index (MDI) was computed, reflecting the degree of adherence to the MedDiet pattern of eating: a higher MDI denoting better adherence. RESULTS: After adjustment for age, BMI, diabetes in the family, weight gain and energy intake, subjects with GDM, by either criterion, had lower MDI (ADA_2010, 5.8 vs 6.3, P=0.028; IADPSG_2012, 5.9 vs 6.4, P<0.001). Moreover, the incidence of GDM was lower in subjects with better adherence to the MedDiet (higher tertile of MDI distribution), 8.0% vs 12.3%, OR=0.618, P=0.030 by ADA_2010 and 24.3% vs 32.8%, OR=0.655, P=0.004 by IADPSG_2012 criteria. In subjects without GDM, MDI was negatively correlated with both fasting plasma glucose and AUC glucose, P<0.001 for both. CONCLUSIONS: Adherence to a MedDiet pattern of eating is associated with lower incidence of GDM and better degree of glucose tolerance, even in women without GDM. The possibility to use MedDiet for the prevention of GDM deserves further testing with intervention studies.

RESUMO

Diabetic cardiomyopathy is a controversial clinical entity that in its initial state is usually characterized by left ventricular diastolic dysfunction in patients with diabetes mellitus that cannot be explained by coronary artery disease, hypertension, or any other known cardiac disease. It was reported in up to 52-60% of well-controlled type-II diabetic subjects, but more recent studies, using standardized tissue Doppler criteria and more strict patient selection, revealed a much lower prevalence. The pathological substrate is myocardial damage, left ventricular hypertrophy, interstitial fibrosis, structural and functional changes of the small coronary vessels, metabolic disturbance, and autonomic cardiac neuropathy. Hyperglycemia causes myocardial necrosis and fibrosis, as well as the increase of myocardial free radicals and oxidants, which decrease nitric oxide levels, worsen the endothelial function, and induce myocardial inflammation. Insulin resistance with hyperinsulinemia and decreased insulin sensitivity may also contribute to the left ventricular hypertrophy. Clinical manifestations of diabetic cardiomyopathy may include dyspnea, arrhythmias, atypical chest pain, and dizziness. Currently, there is no specific treatment of diabetic cardiomyopathy that targets its pathophysiological substrate, but various therapeutic options are discussed that include improving diabetic control with both diet and drugs (metformin and thiazolidinediones), the use of ACE inhibitors, beta blockers, and calcium channel blockers. Daily physical activity and a reduction in body mass index may improve glucose homeostasis by reducing the glucose/insulin ratio and the increase of both insulin sensitivity and glucose oxidation by the skeletal and cardiac muscles.

RESUMO

The transferrin (Tf) family of iron binding proteins includes important endogenous modulators of the immune function that may modulate autoimmune diseases. To define more clearly the role of apotransferrin (apoTf) in type 1 diabetes we determined the impact of this protein on type 1 diabetes as investigated in islet cells, animal models and patient sera. First, we demonstrated that recombinant apoTf counteracts the cytokine-induced death of murine pancreatic islet cells. Secondly, human apoTf administration favourably influences the course of type 1 diabetes in animal models, resulting in protection against disease development that was associated with reduction of insulitis and reduced levels of proinflammatory cytokines. Finally, we confirmed that patients with newly diagnosed type 1 diabetes manifest significantly lower apoTf serum levels compared to healthy controls and patients with long-lasting disease. In conclusion, our data suggest the apoTf pivotal role in the perpetuation of type 1 diabetes pathology.

RESUMO

When we ask people what they value most, health is usually top of the list. While effective care is available for many chronic diseases, the fact remains that for the patient, the tax payer and the whole of society: prevention is better than cure. Diabetes and its complications are a serious threat to the survival and well-being of an increasing number of people. It is predicted that one in ten Europeans aged 20-79 will have developed diabetes by 2030. Once a disease of old age, diabetes is now common among adults of all ages and is beginning to affect adolescents and even children. Diabetes accounts for up to 18 % of total healthcare expenditure in Europe. The good news is that diabetes is preventable. Compelling evidence shows that the onset of diabetes can be prevented or delayed greatly in individuals at high risk (people with impaired glucose regulation). Clinical research has shown a reduction in risk of developing diabetes of over 50 % following relatively modest changes in lifestyle that include adopting a healthy diet, increasing physical activity, and maintaining a healthy body weight. These results have since been reproduced in real-world prevention programmes. Even a delay of a few years in the progression to diabetes is expected to reduce diabetes-related complications, such as heart, kidney and eye disease and, consequently, to reduce the cost to society. A comprehensive approach to diabetes prevention should combine population based primary prevention with programmes targeted at those who are at high risk. This approach should take account of the local circumstances and diversity within modern society (e.g. social inequalities). The challenge goes beyond the healthcare system. We need to encourage collaboration across many different sectors: education providers, non-governmental organisations, the food industry, the media, urban planners and politicians all have a very important role to play. Small changes in lifestyle will bring big changes in health. Through joint efforts, more people will be reached. The time to act is now.

RESUMO

BACKGROUND: The prevalence and socioeconomic burden of type 2 diabetes (T2DM) and associated co-morbidities are rising worldwide. AIMS: This guideline provides evidence-based recommendations for preventing T2DM. METHODS: A European multidisciplinary consortium systematically reviewed the evidence on the effectiveness of screening and interventions for T2DM prevention using SIGN criteria. RESULTS: Obesity and sedentary lifestyle are the main modifiable risk factors. Age and ethnicity are non-modifiable risk factors. Case-finding should follow a step-wise procedure using risk questionnaires and oral glucose tolerance testing. Persons with impaired glucose tolerance and/or fasting glucose are at high-risk and should be prioritized for intensive intervention. Interventions supporting lifestyle changes delay the onset of T2DM in high-risk adults (number-needed-to-treat: 6.4 over 1.8-4.6 years). These should be supported by inter-sectoral strategies that create health promoting environments. Sustained body weight reduction by >or= 5 % lowers risk. Currently metformin, acarbose and orlistat can be considered as second-line prevention options. The population approach should use organized measures to raise awareness and change lifestyle with specific approaches for adolescents, minorities and disadvantaged people. Interventions promoting lifestyle changes are more effective if they target both diet and physical activity, mobilize social support, involve the planned use of established behaviour change techniques, and provide frequent contacts. Cost-effectiveness analysis should take a societal perspective. CONCLUSIONS: Prevention using lifestyle modifications in high-risk individuals is cost-effective and should be embedded in evaluated models of care. Effective prevention plans are predicated upon sustained government initiatives comprising advocacy, community support, fiscal and legislative changes, private sector engagement and continuous media communication.

RESUMO

BACKGROUND: The marked increase of type 2 diabetes necessitates active development and implementation of efficient prevention programs. A European level action has been taken by launching the IMAGE project to unify and improve the various prevention management concepts, which currently exist within the EU. This report describes the background and the methods used in the development of the IMAGE project quality indicators for diabetes primary prevention programs. It is targeted to the persons responsible for diabetes prevention at different levels of the health care systems. METHODS: Development of the quality indicators was conducted by a group of specialists representing different professional groups from several European countries. Indicators and measurement recommendations were produced by the expert group in consensus meetings and further developed by combining evidence and expert opinion. RESULTS: The quality indicators were developed for different prevention strategies: population level prevention strategy, screening for high risk, and high risk prevention strategy. Totally, 22 quality indicators were generated. They constitute the minimum level of quality assurance recommended for diabetes prevention programs. In addition, 20 scientific evaluation indicators with measurement standards were produced. These micro level indicators describe measurements, which should be used if evaluation, reporting, and scientific analysis are planned. CONCLUSIONS: We hope that these quality tools together with the IMAGE guidelines will provide a useful tool for improving the quality of diabetes prevention in Europe and make different prevention approaches comparable.

RESUMO

The Nomenclature Committee of the European Laryngological Society taken the personal classification used by various members were analyzed and integrated into a common format. Thus, a new classification (Remacle et al., 2000) end next modification (Remacle et al., 2007) in was proposed and accepted by the members. This nomenclature takes into account both the histological and anatomical extent of surgery, and groups it into several categories. Subepithelial cordectomy--excision of the epithelium and the superficial layer of the lamina propria. Subligamentous cordectomy--excision of the epithelium, Reinke's space, and vocal ligament is undertaken. Transmuscular cordectomy--resection consists of the epithelium, lamina propria, and part of the vocal fold muscle, and may extend from the vocal process to the anterior commissure. Total or complete cordectomy--excision extends from the vocal process to the anterior commissure. Anteriorly, the incision is made at the anterior commissure. Type Va extended cordectomy--includes the anterior commissure and contralateral vocal fold, if necessary. In type Vb extended cordectomy, the excision is extended to remove part or all of the arytenoids. The posterior arytenoids mucosa is preserved. In Type Vc extended cordectomy, the whole of the ventricle and the ventricular fold is removed together with the vocal fold. In Type Vd extended cordectomy, surgery is extended inferiorly to include the subglottic mucosa. Type VI cordectomy--Anterior billateral cordectomy in this operation surgical intervention is focused on anterior commissure, therefore some authors name it commissurectomy.

RESUMO

OBJECTIVE: This study examined the efficacy and safety of biphasic insulin aspart 30 (BIAsp 30) monotherapy in insulin-naive patients with Type 2 diabetes mellitus. RESEARCH DESIGN AND METHODS: In this 12-week, open-labelled, uncontrolled, clinical-experience study involving 71 patients with secondary oral antidiabetic agent failure, patients received BIAsp 30 after discontinuing oral antidiabetic drugs (OADs). Glucose and lipid concentrations, hypoglycaemic episodes and adverse events were assessed before and after treatment. Patient data were categorised according to previous OADs into the biguanides (BI) plus sulfonylureas/meglitinides (SU/MEG) and SU-only groups. RESULTS: After treatment, glucose and lipid control was significantly improved in both groups, with a greater improvement in the SU-only group. Mean glycated haemoglobin, fasting blood glucose and postprandial blood glucose excursion improved by 2.15 +/- 1.24%, 3.70 +/- 3.18 mmol/l and 1.26 +/- 2.65 mmol/l in the BI plus SU/MEG group, and by 3.09 +/- 1.62%, 6.11 +/- 5.02 mmol/l and 2.06 +/- 2.33 mmol/l in the SU-only group, respectively. Mean high-density lipoprotein cholesterol and triglycerides improved by 0.09 +/- 0.18 mmol/l and 0.94 +/- 1.17 mmol/l in the BI plus SU/MEG group and by 0.09 +/- 0.18 mmol/l and 1.04 +/- 2.72 mmol/l in the SU-only group, respectively. No major hypoglycaemic episodes or serious treatment-related adverse events were reported. CONCLUSIONS: Our study showed that BIAsp 30 treatment safely improved glucose and lipid control in insulin-naive patients with Type 2 diabetes poorly controlled on BI plus SU/MEG and SU-only. Key limitations were the lack of a comparator group and the short study duration.

RESUMO

Previous studies have suggested that the multiple transplants might be equally metabolically efficient to a single regimen for human adult islets. The aim of this study was to compare immunological and metabolic parameters after each of the two regimens of human fetal islets (HFI). Group A single transplants (n = 9) had 180 +/- 20 x 1000 HFI equivalents (IEQs) implanted via a single intramuscular injection. In group B multiple transplants (n = 8) islets were implanted by three consecutive injections of 60 +/- 10 x 1000 IEQs at 7-day intervals. We analyzed the immunological parameters of CD4/CD8 T lymphocyte ratios; islet cell antibodies (ICAs) and insulin antibodies (IAs). We estimated insulin secreting capacity (ISC) as the metabolic parameter. We observed that the CD4+/CD8+ T-cell ratio increased, peaking on day 90, in similar fashion in both groups: day -1: A = 1.18 +/- 0.03 versus B = 1.19 +/- 0.04; on day 90: A = 1.79 +/- 0.09, versus B = 1.75 +/- 0.08 (P = NS) immediately before the decrease in C-peptide levels. Thereafter the ratios rapidly decreased without statistical differences. The levels of ICAs did not change. The levels of IAs, which were increased before transplant, then decreased without statistical differences between the groups. The values of ISC increased after transplant and then decreased similar to the T-cell ratio. Our results demonstrated that regimens of multiple and single HFIs did not show differences in the kinetics of the immunological response presumably mediating graft destruction. The CD4/CD8 ratio increased as the C-peptide level decreased, peaking on day 90 at the time of a decrease in C-peptide. These results may be useful for clinical studies of HFIs for type 1 diabetic patients.

RESUMO

Previous studies suggest that multiple transplantations might be equally efficient to a single regimen for human adult islets. The aim of this study was to compare metabolic parameters after each of the two regimens of human fetal islet (HFI) transplantation in type 1 diabetics. In group A (single transplant, n = 9), 180 +/- 20 x 1000 HFI equivalents (IEQs) were implanted by a single IM injection; in group B (multiple transplants, n = 8) islets were implanted as three consecutive injections (60 +/- 10 x 1000 IEQs) at 7-day intervals. We analyzed the metabolic parameters on days -1, 30, 60, 90, 120, 150, and 180 after the procedure. Among the metabolic parameters, we evaluated insulin secretion capacity-ISC (C peptide, RIA), metabolic control (HbA1c, chromatography), and insulin daily dose IDD. We found that C peptide levels increased, peaking on day 90 (A: 0.38 +/- 0.15; B: 0.34 +/- 0.19 nmol/L, P = NS) and then rapidly decreasing without differences, the HbA1c levels and IDD decreased in the same manner without differences between the groups. Our results demonstrate that multiple and single islet transplant regimens are equally efficient to temporarily restore a significant ISC with improvement of metabolic and clinical parameters. The results imply that the two regimens have an equal clinical value.

RESUMO

The aim of this study was to estimate the possibility of predicting the course of type 1 diabetes. We analyzed the importance of islet cell antibody levels and residual beta cell function in 46 newly diagnosed patients with diabetes. Islet cell antibodies (ICAs; Juvenile Diabetes Foundation [JDF] units) were determined at the time of diagnosis by the indirect immunofluorescent method. beta cell function was estimated by C peptide levels (nmol/L) before and after glucagon stimulation at the time of clinical remission. Of the 46 patients, 13 were ICA negative (group A). Among ICA-positive patients, ICAs were < 20 JDF units (group B) in 15, between 20 and 80 JDF in 9 (group C), and > 80 JDF in 9 (group D). In group A, 9 patients had clinical remission for 7.5 +/- 1.7 months. Their basal C peptide level was 0.26 +/- 0.05 nmol/L and it increased after stimulation to 44.5 +/- 2.5%. Ten patients in group B had remission for 6.2 +/- 1.5 months. Their basal C peptide levels (0.28 +/- 0.07 nmol/L) were similarly increased after stimulation (47.5 +/- 2.5%). In group C, all patients had remission and it was of the longest duration (14.7 +/- 1.5 months). They had the highest basal C peptide levels (0.45 +/- 0.12 nmol/L) with increases to 57.5 +/- 3.5%. Seven patients in group D with ICA levels > 80 JDF had a short remission (3.2 +/- 1.2 months) despite good basal C peptide levels (0.42 +/- 0.05 nmol/L) and excellent increases after stimulation (92.5%). Our results suggest that moderate levels of ICA are associated with good residual beta cell function and longer remission. Very high ICA levels (> 80 JDF) at the time of diagnosis despite better beta cell function are associated with short clinical remission. Therefore, high ICA levels could be a marker of strong autoimmune reaction and accelerated depletion of beta cell function.
