Materials and Methods: We prospectively evaluated eight patients and six healthy controls with single voxel magnetic resonance (MR) spectroscopy throughout 2017 using 3-Tesla MR unit. Metabolite levels measured from the left posterior paracingulate white matter. Raw images were processed with Tarquin version 4.3.10 and area under curve values were automatically calculated for GABA (γ-Aminobutyric acid), Ins (myo-inositole), tNAA (N-Acetylaspartate), tCho (total choline), tCr (total creatine) and GLx (glutamine + Glutamat). Major metabolite levels and all metabolites ratio to tCr calculated and compared between two groups using Mann-Whitney U test. Results: GABA/tCR value of the patients (0.589 ± 0.194, median = 0.515) was significantly higher than control group (0.230 ± 0.067, median = 0.220) (P = 0.002). tNAA/tCR value of the patients (1.106 ± 0.218, median: 1.205), was significantly lower than the control group (1.538 ± 0.401, median: 1.705) (P = 0.028). No significant difference was observed between two groups in terms of all other metabolites (P > 0.05). Conclusion: We demonstrated increased GABA and decreased NAA in the left posterior paracingulate region in BMS patients. We suggest that these metabolite alterations in central nervous system might play a key role in the etiology of the disease by inhibiting the suppression of burning sensation.展开更多

The direct and indirect costs of the disease can be substantial both for the health care system and society. The aim of this research is to estimate the cost of mild, moderate and severe CSU in Turkey and to forecast the cost of the disease from the payer (Social Security Institution—SSI) perspective. Expert opinions with Delphi technique were used in order to determine the cost items and their frequency. A questionnaire was designed to outline resources used in the out-patient, inpatient and emergency care episodes and was answered by dermatologists followed by a consensus meeting. Unit costs were calculated from the price list of the SSI. The annual total cost of treating the disease to the SSI was estimated as 262,111,978TL (94,417,870€) comprising 0.06% of the total healthcare budget in 2013. Since there is limited information about the cost of CSU in Turkey, the methodology and results of this study are unique and very important.展开更多
