The large flexion gap could influence the late rollback under non-WB conditions and better WOMAC functional scores in the flexion items. Three to four millimetre laxity at 90°-0° component gaps may be adequate and might be necessary to carry out daily life activities.
Although the association between periodontitis (PD) and acute myocardial infarctions (AMIs) is known, it is unclear whether the severity of the PD is associated with the atherosclerotic cardiovascular status (ASCVS) degree in patients with AMIs. We prospectively investigated 50 patients with AMIs admitted to the Nihon University Itabashi Hospital from July 2019 to May 2022. All patients were classified according to the presence and severity of the PD. The periodontal status was defined by radiographic bone loss in accordance with previous studies (healthy; ≥80% remaining bone [RB], mild-moderate PD; 66 ≤ RB < 80%, and severe PD; RB < 66%), and the degree of the ASCVS was compared. The low-density lipoprotein/high-density lipoprotein ratio significantly increased from healthy to mild-moderate PD to severe PD. The SYNTAX score was numerically higher according to the severity of the PD. The carotid intima-media thickness (cIMT) (p = 0.025) and E/e’ value (p = 0.009) were highest in the severe PD group. The cIMT and E/e’ had a significant negative correlation with the PD (Person’s correlation coefficients; r=-0.296, p = 0.037, and r=-0.411, p = 0.003, respectively). We found that the severity of the PD was associated with carotid atherosclerosis and cardiac diastolic dysfunction in AMI patients, suggesting the importance of scrutinizing PD in AMI practice.
Schwannoma is an uncommon benign tumor in the oral and maxillofacial region, and development of schwannoma in the lower lip is rare. Herein, we present the case of a 68-year-old woman who visited Nihon University Itabashi Hospital complaining of a painless mass in the lower lip. The lesion was surgically resected under local anesthesia.On histopathological examination, the resected specimen was a mixture of Antoni types A and B schwannoma. No recurrence has been seen over a postoperative follow-up period of 58 months. In the schwannoma of the lower lip, the mean tumor volume was compared for type A and the mixed type, which tended to be larger in the mixed type.No previous reports have described the relationship between the size of schwannoma in the lower lip and Antoni classification. Therefore, this report discusses the possibility of a relationship between tumor size and Antoni classification for schwannomas in the lower lip.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
