In this study, a presurgical implant decision in a case of SAPHO (synovitis, acne, palmoplantar pustulosis, hyperostosis, osteitis) is described. Since the etiology of this syndrome is likely to involve genetic, infectious and immunological components, lipopolysaccharides (LPS) may conceptually trigger cytokine production leading to a specific chronic inflammation and immunological host response. This may hamper proper healing or accentuate the destruction of periodontal host tissues. In our approach, we examined the ex vivo cell viability and immune responses of primary osteoblasts and keratinocytes under sterile inflammation induced by P. gingivalis LPS. Keratinocytes and osteoblasts were obtained from biopsies of the keratinized gingiva and alveolar bone tissues of a SAPHO human subject. Enzymatically dissociated cells were thus cultured and incubated to LPS at different concentrations (50ng/ml, 200ng/ml, 500ng/ml and 1μg/ml) for 24 h in order to test inflammatory cytokine response (quantitative real time PCR) and toxicity (cell viability). Healthy primary keratinocytes and osteoblasts were used as control cells. The highest concentration of LPS (1μg/ml) significantly reduced cell viability (p < 0.05). Meanwhile, all tested LPS concentrations similarly enhanced the mRNA expressions of selected inflammatory cytokines (TNFα, IL-6, IL-8, IL-1β and IL-1𝛼) up to ≈3.5-fold, when compared to the healthy cell controls (p < 0.05). This study demonstrated a valuable inflammatory risk evaluation before implant placement, which was successfully performed based on the presented laboratory diagnostic/prognostic approach.Sapho.</p>","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"133 5","pages":"297-303"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9482246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This retrospective analysis included 160 patients who received primary resection of oral squamous cell carcinoma and concurrent neck dissection. It aimed to investigate how well quality metrics were met during a 6-year period in the department of oral and maxillofacial surgery at a university hospital. 93.1% of patients were seen in the specialist's office within 21 days after referral.
