PURPOSE: Patient-reported outcomes are increasingly commonly used as a method of evaluating treatments. This cross-sectional study aimed to evaluate implant treatment from the perspective of patient-reported outcomes. MATERIALS AND METHODS: Subjects were 804 patients who visited the Department of Oral Implantology at Osaka Dental University. The participants were categorized into a pre-implant group and a post-implant group. They were further categorized into five subgroups based on the number of occlusal supports provided by the remaining teeth according to the Eichner classification. The participants answered a basic questionnaire and the General Oral Health Assessment Index (GOHAI) questionnaire, an oral health-related quality of life (QOL) scale. GOHAI scores were compared according to the number of occlusal supports within each group and between the two groups. RESULTS: The results revealed a significant difference in terms of the number of occlusal supports within the pre-implant group; GOHAI scores decreased as the number of occlusal supports decreased (P < .001). However, no significant difference was observed in GOHAI scores in terms of the number of occlusal supports in the post-implant group (P>.05). GOHAI scores significantly improved in both pre- and post-implant groups in all occlusal support subgroups (P < .001). CONCLUSION: GOHAI scores decrease as occlusal support is lost. However, implant treatment performed in areas of loss improves the GOHAI score when occlusal support is restored.

No study has described Streptococcus dysgalactiae subsp. equisimilis (SDSE) isolates that cause repetitive infections (recurrence and reinfection). We compared the microbiological characteristics of SDSE causing repetitive infections with those causing single infections. Three patients with invasive infections were identified based on their medical records, and multiple SDSE isolates were collected at intervals over three weeks, using a laboratory repository. Isolates from 12 patients with single-episode infections served as controls. Six isolates were collected from three patients with first and second episodes of infection. All isolates causing either repetitive or single-episode infection were subjected to emm typing, multilocus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE), and random amplified polymorphic DNA (RAPD) analyses. Amplification of five virulence genes (sicG, prtF1, prtF2, lmb, and cbp), biofilm formation (BF), and cell invasion abilities (CIAs) were measured as virulent phenotypes. We observed close genetic similarities in the data obtained by emm typing, MLST, PFGE, and RAPD in four isolates from two patients, suggesting recurrence, whereas two isolates from one patient indicated genetic differences in these data, suggesting re-infection. The presence of the five virulence genes and the BF and CIA measurements appeared not to contribute to repetitive infections, compared with isolates causing single-episode infection. In conclusion, clinicians encountering patients with repetitive infections should be aware of both possibilities: recurrence with closely related strains and reinfection with different strains.

Endoscopic ultrasonography (EUS) is widely used to evaluate pancreaticobiliary diseases, especially pancreatic masses. EUS has a good ability to detect pancreatic masses, but it is not sufficient for the differential diagnosis of various types of lesions. In order to address the limitations of EUS, new techniques have been developed to improve the characterization of the lesions detected by EUS. EUS-guided fine needle aspiration (EUS-FNA) has been used for diagnosing pancreatic tumors. In order to improve the histological diagnostic yield, a EUS-FNA needle with a core trap has recently been developed. Contrast-enhanced harmonic EUS is a new imaging modality that uses an ultrasonographic contrast agent to visualize blood flow in fine vessels. This technique is useful in the diagnosis of pancreatic solid lesions and in confirming the presence of vascularity in mural nodules for cystic lesions. EUS elastography analyzes several different variables to measure tissue elasticity, color patterns, and strain ratio, using analytical techniques such as hue-histogram analysis, and artificial neural networks, which are useful for the diagnosis of chronic pancreatitis and pancreatic cancer.

While there is an emphasis on fostering the next generation of medical educators, it is difficult for the younger generation to find opportunities to deepen their knowledge of medical education regularly amid their busy clinical work. Using journal clubs is a strategy for lifelong learning in the professional field; yet, it is difficult to operate and maintain one. We established an online journal club for medical education and research with 9- to 12-year post-graduates from different institutions across Japan. While it is generally said that even face-to-face journal clubs are difficult to sustain, we were able to hold more than 40 online meetings in one year. We discussed why our approach was feasible, citing social congruence theory and self-determination theory.
