The association between halitosis and periodontitis: a systematic review and meta-analysis.

OBJECTIVES: The purpose of this systemic review and meta-analysis was to explore the association between halitosis and periodontitis in observational studies. MATERIALS AND METHODS: A systematic search covered PubMed, Web of Science, Embase, Scopus, and Cochrane Library until August 18, 2023. Nine observational studies (585 cases, 1591 controls) were analyzed using Stata 17, with odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup analyses considered halitosis assessment methods. RESULTS: The review found a positive association between halitosis and periodontitis. Significant differences were observed with organoleptic test (OR = 4.05, 95% CI: 1.76, 9.30, p < 0.01) and volatile sulfur compound readings (OR = 4.52, 95% CI: 1.89, 10.83, p < 0.01). CONCLUSIONS: A positive association was observed between halitosis and periodontitis, supported by significant differences in both organoleptic and volatile sulfur compound readings. However, conclusive findings are limited by statistical heterogeneity, emphasizing the need for additional research. CLINICAL RELEVANCE: Understanding the halitosis and periodontitis association is clinically significant, informing potential interventions for improved oral health. Further research is vital to refine understanding and guide effective clinical strategies, acknowledging the limitations in current findings.

Efficacy comparison of immediate breast reconstruction after breast cancer surgery and modified radical mastectomy / 肿瘤研究与临床

Objective To investigate the clinical efficacy and cosmetic outcome of two methods of immediate breast reconstruction and modified radical mastectomy for the patients with breast cancer after breast cancer surgery. Methods The clinical data of 95 patients with early breast cancer in the First Affiliated Hospital of Jinzhou Medical University from October 2014 to September 2018 were retrospectively analyzed. The patients were divided into latissimus dorsi combined with implants group (27 cases), titanium-coated polypropylene mesh combined with implants group (18 cases) and modified radical group (50 cases). The differences of surgical data, postoperative complications and quality of life were compared in the three groups. The postoperative cosmetic effect of two immediate reconstruction groups was observed. Results The differences of drainage duration and intraoperative blood loss in the three groups were not statistically significant (both P > 0.05). There were statistical differences in the hospital stay and the postoperative quality of life score (both P < 0.01). The incidence of postoperative complications in latissimus dorsi combined with implants group, the titanium-coated polypropylene mesh combined with implants group and the modified radical group was 48.1％ (13/27), 22.2％ (4/18) and 12.0％ (6/50), respectively. And the difference between latissimus dorsi combined with implants group and the modified radical surgery group was statistically significant (χ 2 = 12.33, P < 0.01). The good rate of cosmetic effect in titanium-coated polypropylene mesh group was higher than that in latissimus dorsi combined with implants group, and there was no statistically significant difference [83.3％ (15/18) vs. 81.5％ (22/27), χ 2 = 0.025, P > 0.05]. Conclusions Immediate breast reconstruction including latissimus dorsi combined with implants or titanium-coated polypropylene mesh combined with implants after radical mastectomy on the basis of indications can improve the quality of life and the cosmetic results of patients, but postoperative treatment is necessary for the increased complications after the two reconstruction methods.
