Filter by:Rheumatoid arthritis (RA) is one of the most common autoimmune inflammatory arthritis affecting 0.5 to 1% population worldwide characterized by synovitis, increased inflammatory markers and progressive bone and cartilage erosion. RA is associated with an increased cardiovascular morbidity and mortality compared with the general population.
Oral diseases tend to be exacerbated due to delayed diagnosis. Patients avoid visiting their dentist even for regular checkups, and develop late stage disease, jeopardizing the treatment outcome. There is an urgent need for an inexpensive and minimally invasive technology that would serve as a diagnostic aid, allowing 1) efficient early detection and 2) treatment customization. Diagnostic modalities based on the detection of volatile organic compounds in the exhaled air may answer this need. The proposed research aims at investigating signature molecular patterns of common oral diseases, as a first step toward the development of a computerized non-invasive diagnostic breath test, based on the "Na-Nose" device. The proposed research will be divided to three distinct stages. Stages 1-2 will serve for the detection and analysis of Volatile Organic Compounds connected with common oral diseases, and for the characterization of a specified diagnostic nano-receptor array. Stage 3 will serve for the clinical testing of the array and as a proof of concept. In a pilot experiment, headspaces above colonies of S.mutans, S.sanguis, P.gingivalis and F.nucleatum were trapped and analyzed using Gas Chromatography Mass Spectrometry (GC-MS). A unique VOC signature, consisting of 20-35 molecules, was detected for each of the bacterial strains. These promising results allow the development of an algorithm for statistical detection of oral diseases by their VOC profile alone. Bacteria and distressed tissues emit unique VOCs, and additional research is required with other types and strains of bacteria - including cultivation of samples from active periodontal and carious lesions. The results of the proposed research may be revolutionary. A simple and non-invasive air sampling at home or in a drugstore will significantly increase patient compliance and curability rates, and decrease healthcare expenditure.
Periodontitis is a destructive chronic infection of the gums, ligaments, and bone, predominantly caused by Gram-negative bacteria. Individuals with periodontal disease are at increased risk of systemic diseases. Increased prevalence of periodontal disease has been reported in patients with chronic kidney disease, especially in dialysis patients. Chronic kidney disease (CKD) is the progressive loss of kidney function over time. When kidneys loose their 85-90 % function, dialysis is performed. Efficacy of dialysis is checked by serum albumin levels. Lower-than-normal levels of serum albumin may be a sign of kidney diseases. Hypoalbuminemia has been demonstrated to be a strong predictor of death in chronic renal failure. A proposed mechanism for the effect of periodontitis on the development of kidney disease is systemic inflammation. The deleterious effects of systemic inflammation on kidney function could occur during the period of active periodontal infection and accumulate during the life time of the individual. This randomized control trial is designed to observe the effect of non-surgical periodontal therapy on serum albumin levels of patients on maintenance hemodialysis therapy. Patients will undergo periodontal examination and their serum albumin levels will be checked. Then they will be randomly divided in two groups. One group will be given non surgical periodontal treatment and second group will be offered late treatment. After 6 weeks 1st group will be reevaluated by serum albumin level and periodontal examination to observe the effect of non-surgical periodontal therapy. Statistical analyses shall be performed using SPSS software. T tests and Chi-sq tests shall be used to test differences according to periodontal status for continuous and categorical variables, respectively. The level of significance is set at p<0.05.
