Several factors have been reported as risk factors for the development of osteoporosis. In this study, we aimed to examine the relationship among lifestyle factors, biologic factors, and bone mineral density (BMD) using structural equation modeling (SEM). The subjects in the present study consisted of 866 postmenopausal Japanese women aged between 40 and 80 years old. In the analysis by the SEM, we employed a multiple basic model. As the structural variables, lifestyle factors and biologic factors were selected. The goodness of fit index (GFI) of the final model was 0.991 and the Akaike’s information criteria (AIC) showed the lowest value in the peripheral models. The degree of association between biologic factors and BMD was −0.576 (direct association), 0.012 (indirect association), and −0.564 (total association). With regard to the correlation between lifestyle factors and BMD, the degrees of association were 0.085, −0.084, and 0.001, respectively. This study defined a pilot model for factors influencing BMD. Although is remains necessary to conduct further analyses with more valid measurements and constructs, this model indicated that the correlation between BMD and lifestyle factors was lower than that between BMD and biologic factors.

At Tokyo Women's Medical University, our curriculum for first-year students is designed to teach the dynamics and etiquette of human relations. During the third year, medical students are expected to anticipate and plan effective therapeutic communication and interaction with patients. A discussion group of 6 students and a member of the human-relations committee first clarify the purpose and develop the training; students then independently participate in human-relations training during the summer vacation. After training, experiences are discussed during class. Although this curriculum has been used for some 10 years, its benefits have been assumed but not validated. We used student reports and questionnaires to examine the effects of this curriculum. The results clearly show that planning and training give the students an opportunity to learn how to establish an effective physician-patient relationship.

Background/Aims:
Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis and handsewn anastomosis for ulcerative colitis requires pulling down of the ileal pouch into the pelvis, which can be technically challenging. We examined risk factors for the pouch not reaching the anus.
Methods:
Clinical records of 62 consecutive patients who were scheduled to undergo RPC with handsewn anastomosis at the University of Tokyo Hospital during 1989–2019 were reviewed. Risk factors for non-reaching were analyzed in patients in whom hand sewing was abandoned for stapled anastomosis because of nonreaching. Risk factors for non-reaching in laparoscopic RPC were separately analyzed. Anatomical indicators obtained from presurgical computed tomography (CT) were also evaluated.
Results:
Thirty-seven of 62 cases underwent laparoscopic procedures. In 6 cases (9.7%), handsewn anastomosis was changed to stapled anastomosis because of non-reaching. Male sex and a laparoscopic approach were independent risk factors of non-reaching. Distance between the terminal of the superior mesenteric artery (SMA) ileal branch and the anus > 11 cm was a risk factor for non-reaching.
Conclusions
Laparoscopic RPC with handsewn anastomosis may limit extension and induction of the ileal pouch into the anus. Preoperative CT measurement from the terminal SMA to the anus may be useful for predicting non-reaching.

Objective This study aimed to identify the types, frequency, and clinical significance of altered interpreta-tion in clinical settings.Methods Routine outpatient encounters involving Portuguese-speaking Brazilian patients, Japanese doctors, and hospital-provided interpreters were digitally recorded and transcribed. Segments of consecutively interpreted utterances were coded as “altered,” in which the interpreter changed the meaning of the source utterance, or “unaltered (accurate),” and the types and frequency of occurrence were analyzed. Altered interpretations were categorized as clinically negative or positive and classified into four categories: omission, addition, substitution, or voluntary intervention. Incidents resulting from alterations were investigated. Reliability was assessed by examining the correlation between random independently coded samples.Results In total, 111 encounters were analyzed. The mean segments per encounter was 67.9 (range 14-186), and the mean frequency (standard deviation) of altered interpretations per 100 segments was 46.7 (14.3) for accurate interpretations; 46.1 (17.9) for negative or not significant alterations, including 27.2 (10.3) for omissions, 6.0 (5.0) for additions, 10.4 (6.9) for substitutions, and 2.5 (2.7) for voluntary interventions; 0.0 (0.2) for alterations potentially leading to an incident; and 26.2 (11.9) for positive alterations, including 1.8 (2.6) for positive omissions, 7.7 (4.7) for positive additions, 7.8 (6.3) for positive substitutions, and 8.8 (5.2) for positive voluntary interventions. The frequency of negative alterations was weakly negatively correlated with number of segments per minute (r=−0.339). Conclusion Trained healthcare interpreters with fewer clinically significant altered interpretations were effective. Professional medical providers should recognize the importance of positive alterations by healthcare interpreters and collaborate with them to provide safe medical care for foreign patients. To facilitate the provision of appropriate medical care to a growing foreign population with diverse cultural and linguistic needs, undergraduate medical education should teach aspiring medical professionals how to collaborate with healthcare interpreters and foreign patients.

Treatment of perianal and vulvar extramammary Paget disease (EMPD), rare intraepithelial malignancies, is often challenging because of its potential to spread into the anal canal. However, there is still no consensus regarding the optimal resection margin within the anal canal. Between 2004 and 2014, six patients (three with perianal EMPD and three with vulvar EMPD) in which the spread of Paget cells into the anal canal was highly suspected were referred to our department. To evaluate the disease extent within the anal canal, preoperative mapping biopsy of the anal canal was performed in five out of six patients. Two patients were positive for Paget cells within the anal canal (one at the dentate line and the other at 0.5 cm above the dentate line), whereas in three patients, Paget cell were present only in the skin of the anal verge. Using 1 cm margin within the anal canal from the positive biopsy sites, we performed anal-preserving wide local excision (WLE), and negative resection margins within the anal canal were confirmed in all five patients. The remaining one patient with perianal EMPD did not undergo mapping biopsy of the anal canal because preoperative colonoscopy revealed that the Paget cells had spread into the lower rectum. Therefore, WLE with abdominoperineal resection was performed. During the median follow-up period of 37.3 months, no local recurrence was observed in all patients. Our small case series suggest the usefulness of mapping biopsy of the anal canal for the treatment of perianal and vulvar EMPD.

OBJECTIVE: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease. METHODS: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease. RESULTS: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery. CONCLUSION: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium.
