BACKGROUND: Surgery appears to yield better results in adult spinal deformity treatment when fixed minimum clinically important difference values are used to define success. Our objective was to analyze utilities and improvement provided by surgical versus nonsurgical treatment at 2 years using Oswestry Disability Index with treatment-specific minimum clinically important difference values. METHODS: From a multicenter database including 1452 patients, 698 with 2 years of follow-up were analyzed. Mean age of patients was 50.95 +/- 19.44 years; 580 patients were women, and 118 were men. The surgical group comprised 369 patients, and the nonsurgical group comprised 329 patients. The surgical group was subcategorized into no complications (192 patients), minor complications (97 patients) and major complications (80 patients) groups to analyze the effect of complications on results. Minimum clinically important differences using Oswestry Disability Index were 14.31, 14.96, and 2.48 for overall, surgical, and nonsurgical groups. Utilities were calculated by visual analog scale mapping. RESULTS: Surgical treatment provided higher utility (0.583) than nonsurgical treatment (0.549) that was sensitive to complications, being 0.634, 0.564, and 0.497 in no, minor, and major complications. Probabilities of improvement, unchanged, and deterioration were 38.3%, 39.2%, and 22.5% for surgical treatment and 39.4%, 10.5%, and 50.1% for nonsurgical treatment. Improvement in the surgical group was also sensitive to complications with rates of 40.1%, 39.3%, and 33.3%. CONCLUSIONS: Our results suggest that surgical treatment has less disease burden and less chance of deterioration, but equal chances for improvement at 2 years of follow-up. As it appears to be a better modality in the absence of complications, future efforts need be directed to decreasing the complication rates.

Objective: To evaluate the effects of fixed orthodontic treatment with steel-ligated conventional brackets and self-ligating brackets on halitosis and periodontal health. Materials and Methods: Sixty patients, at the permanent dentition stage aged 12 to 18 years, who had Angle Class I malocclusion with mild-to-moderate crowding were randomly selected. Inclusion criteria were nonsmokers, without systematic disease, and no use of antibiotics and oral mouth rinses during the 2-month period before the study. The patients were subdivided into three groups randomly: the group treated with conventional brackets (group 1, n = 20) ligated with steel ligature wires, the group treated with self-ligating brackets (group 2, n = 201, and the control group (group 3, n = 20). The periodontal records were obtained 1 week before bonding (T1), immediately before bonding (T2), 1 week after bonding (T3), 4 weeks after bonding (T4), and 8 weeks after bonding (T5). Measurements of the control group were repeated within the same periods. The volatile sulfur components determining halitosis were measured with the Halimeter at T2, T3, T4, and T5. A two-way repeated measures of analysis of variance (ANOVA) was used to compare the groups statistically. Results: No statistically significant group x time interactions were found for plaque index, gingival index, pocket depth, bleeding on probing, and halitosis, which means three independent groups change like each other by time. The risk of tongue coating index (TCI) being 2 was 10.2 times higher at T1 than at T5 (P < .001). Therefore, the probability of higher TCI was decreased by time in all groups. Conclusions: The self-ligating brackets do not have an advantage over conventional brackets with respect to periodontal status and halitosis.

Although brucellosis is very common in the world and Turkiye, there are no evidence-based guidelines to guide the diagnosis and treatment of the disease. This guide has been prepared by the Turkish Society of Clinical Microbiology and Infectious Diseases to provide evidence-based recommendations to physicians from different specialties interested in the diagnosis and treatment of brucellosis. The recommendations of the Clinical Practice Guide Development Guide of the Infectious Diseases Society of America (IDSA) were taken as the basis for preparing this guide. The guideline preparation group determined 20 questions considered to be important in the diagnosis and treatment of brucellosis, and the publications that could answer these questions prepared in PICO (Population/Patient [P], Intervention [I], Comparison [C], Outcome [O]) format, were searched in ULAKBIM Tr Dizin, PubMed, Cochrane databases without date restrictions. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group method was used to rank the evidence and determine the strength of the recommendations for each PICO question and for each individual outcome. Meta-analyses of comparative clinical studies were performed to answer the PICO questions. Individual participant data (IPD) meta-analyses with data obtained from case reports and case series were conducted in the absence of comparative clinical studies. It is planned to update the recommendations at regular intervals in line with the results of new studies.
