Objective Symptoms (objective + symptom)
Selected AbstractsFrequency spectrum of condylar movement in clinically normal subjects, using an amorphous sensorJOURNAL OF ORAL REHABILITATION, Issue 7 2004H. Ioi summary, The purpose of this study was to determine the properties of the frequency spectrum produced by condylar movements in normal subjects, by the use of an amorphous sensor. The gender-matched sample consisted of white people (17 males and 17 females, aged 25·8 ± 2·5 and 25·5 ± 2·8 years, respectively) who had no subjective or objective symptoms related to temporomandibular joint sounds. Bilateral condylar and jaw movements were recorded simultaneously. The results showed that the mean ± standard deviation (s.d.) for the mean frequency of condylar movement during the opening and closing phases was 45·0 ± 5·2 and 47·0 ± 3·5 Hz, respectively. The mean ± s.d. for the peak frequency of condylar movement during the opening and closing phases was 46·6 ± 8·0 and 49·7 ± 4·5 Hz, respectively. Significant correlations existed between the left and right sides in the mean frequency as well as the peak frequency during the opening phase. However, there were no significant correlations between the left and right sides in the mean frequency or the peak frequency during the closing phase. These results suggest that the frequency spectrum of normal condylar movement can be obtained when using the amorphous sensor. [source] When is an oral food challenge positive?ALLERGY, Issue 1 2010B. Niggemann Abstract Oral food challenges still remain the gold standard in the diagnosis of food related symptoms and are performed to obtain a clear ,yes or no' response. However, this is often difficult to achieve, and so proposals may be appropriate for criteria on when to stop oral food challenges. In daily practice it makes sense to challenge until clear objective symptoms occur without harming the patient. Clinical symptoms should be objective and/or: (a) severe or (b) reproducible or (c) persisting. A sensitive parameter for a beginning clinical reaction is a general change of mood. The sooner symptoms appear, the more likely they are to represent a ,true' positive reaction and the more organ systems are involved the easier it is to assess an oral food challenge as positive. In the case of subjective symptoms, the number of placebo doses should be increased. In unclear situations, the observation time until the next dose should be prolonged or the same dose repeated. Transient objective clinical symptoms usually end up in a positive challenge result. There are a number of causes for false positive and false negative challenge results, which should be considered. The aim of all oral challenge testing should be to hold the balance between two conflicting aspects: on the one hand the need to achieve clear and justified results from oral food challenges in order to avoid unnecessary diets, and on the other hand to protect patients from any harm caused by high doses of a potentially dangerous food.

Kok First page of article [source] Do adverse effects of dental materials exist?CLINICAL ORAL IMPLANTS RESEARCH, Issue 2007What are the consequences, how can they be diagnosed, treated? Abstract Objectives: All dental biomaterials release substances into the oral environment to a varying degree. Various preclinical biocompatibility test systems have been introduced, aiming at an evaluation of the potential risks of dental materials. Potential pathogenic effects of released substances from dental materials have been demonstrated. For the biocompatibility of a biomaterial, it is not only important that minimal diffusable substances are released when it is in body contact , the material must also fulfill the function for which it has been designed. This is also very much dependent on the material properties and its handling properties. The aim of this review was to generate an overview of the present status concerning adverse reactions among patients and personnel. Materials and methods: A systematic review was performed using a defined search strategy in order to evaluate all MEDLINE-literature published between 1996 and 2006. Results: The compilation of the literature available has revealed that the majority of studies have been carried out on patients compared with personnel. Adverse reactions towards dental materials do occur, but the prevalence and incidence are difficult to obtain. The results were essentially based on cohort studies. Clinical trials, especially randomized-controlled trials, are in the minority of all studies investigated, with the exception of composite and bonding studies, where clinical trials, but not randomized-controlled trials, represent the majority of studies. Patients and personnel were treated separately in the manuscript. Amalgam studies show the lowest degree of verified material-related diagnosis. Even if objective symptoms related to adverse reactions with polymer resin-based materials have been reported, postoperative sensitivity dominates reports concerning composites/bondings. Verified occupational effects among dental personnel show a low frequency of allergy/toxic reactions. Irritative hand eczema seemed to be more common than in the general population. Conclusions: Patient- and personnel-related studies are of variable quality and can be improved. There is a need for a better description of the content of materials. A registry for adverse effects of dental materials would be useful to detect the occurrence of low-incidence events. [source] | ||||||||||
