  Introduction: The Great East Japan Earthquake and tsunami of March 11, 2011, devastated large areas of northeastern Japan. Medical students participated in the medical support teams dispatched by Tohoku University Hospital to the devastated areas. However, whether participation in such medical support teams affects the learning attitudes and future careers of medical students has not been examined.
  Methods: We used a questionnaire to investigate how 19 students who participated in medical support teams thought their participation would affect their learning attitudes and future careers. We analyzed the results by simple tabulation.
  Results: After participating, many students thought that they would have to study harder because they had been able to do nearly nothing by themselves for the people in the devastated areas. They also stated that they wanted to work in the Tohoku district in the future.
  Discussion: These results suggest that the participation of medical students in medical support teams for devastated areas encourages them to study harder, probably because they recognize the importance of health care in society. The results also suggest that participation provides students with opportunities to consider their future careers from a different point of view.

AIMTo show whether molecular motor dynein on a microtubule track, molecular motor myosin Va, motor recruiter myosin Va, VIIa-Rab27a/b interacting protein (MyRIP), and vesicle receptor Rab27b on an F-actin track were present during human and monkey spermiogenesis involving intramanchette transport (IMT).

METHODSSpermiogenic cells were obtained from three men with obstructive azoospermia and normal adult cynomolgus monkey (Macaca fascicularis). Immunocytochemical detection and reverse transcription-polymerase chain reaction (RT-PCR) analysis of the proteins were carried out. Samples were analyzed by light microscope.

RESULTSUsing RT-PCR, we found that dynein, myosin Va, MyRIP and Rab27b were expressed in monkey testis. These proteins were localized to the manchette, as shown by immunofluorescence, particularly during human and monkey spermiogenesis.

CONCLUSIONWe speculate that during primate spermiogenesis, those proteins that compose microtubule-based and actin-based vesicle transport systems are actually present in the manchette and might possibly be involved in intramanchette transport.

Europe has a long history with its own traditional medicines. In Germany, the practice of traditional European and Asian medicine along with modern medicine is called Integrative Medicine. The pain clinics at Munich University, TCM Klinik Bad Kotzting, Immanuel Klankenhaus and Zen Haus Klinik are well-known centers of Integrative Medicine in Germany. We visited these hospitals and clinics and report on the state of their treatment.
Four-week programs in chronic pain, traditional Chinese medicine, natural therapy, and traditional Japanese medicine with aromatherapy are given at these facilities. Moreover, Complementary and Alternative medicines are widely covered by public or private insurance. And one reason for the spread of Integrative Medicine may be these social conditions, in addition to historical background.

OBJECTIVE: The Japan Society of Gynecologic Oncology (JSGO) initiated a nation-wide training system for the education and certification for gynecologic oncologists in 2005. To assess the impact of the quality of the JSGO-accredited institutions, JSGO undertook an analysis of the Uterine Cervical Cancer Registry of the Japan Society of Obstetrics and Gynecology (JSOG) to determine the effectiveness of the JSGO-accredited institutions on the treatment and survival of women with cervical cancer. METHODS: The effectiveness of 119 JSGO-accredited institutions and 125 non-JSGO-accredited institutions on the treatment and survival of women with cervical cancer were compared by analyzing the tumor characteristics, treatment patterns, and survival outcomes of women with stage T1B–T4 cervical cancer utilizing the data in the JSOG nation-wide registry for cervical cancer (2006–2009). RESULTS: A total of 14,185 eligible women were identified: 10,920 (77.0%) cases for 119 JSGO-accredited institutions and 3,265 (23.0%) cases for 125 non-accredited institutions. A multivariate analysis showed that age, stage, histology type, and treatment pattern were independently associated with mortality. Moreover, women who received treatment at the JSGO-accredited institutions had a significantly decreased mortality risk compared to non-accredited institutions (adjusted hazard ratio [aHR]=0.843; 95% confidence interval [CI]=0.784–0.905). Similar findings on multivariate analysis were seen among subset of women who received surgery alone (aHR=0.552; 95% CI=0.393–0.775) and among women who received radiotherapy (aHR=0.845; 95% CI=0.766–0.931). CONCLUSION: Successful implementation of gynecologic oncology accrediting institution was associated with improved survival outcome of women with cervical cancer in Japan.

Objective: The objective of this study was to examine the current trends in fertility-sparing (FS) treatment for young atypical endometrial hyperplasia (AEH) and endometrial cancer (EC) patients in Japan. Methods: This study was conducted by the Committee on Gynecologic Oncology of the Japan Society of Obstetrics and Gynecology (JSOG) in the 2017–2018 fiscal year. A nationwide, retrospective questionnaire-style survey—as performed. We collected the data of 413 patients from 102 JSOG gynecological cancer registered institutions. Results: FS treatment was performed with medroxyprogesterone (MPA) (87.2%) or MPA + metformin (11.6%). Pathological complete remission (CR) after initial treatment was achieved in 78.2% of patients. The significant clinicopathological factors correlated to CR after initial treatment were histology (AEH vs. endometrioid carcinoma grade 1 [ECG1]), body mass index (BMI) (<25 vs. ≥25 kg/m2), and treatment period (<6 vs. ≥6 months). ECG1, time to complete remission (TTCR) ≥6 months, maintenance therapy (−), and pregnancy (−) were associated with a significantly higher risk of recurrence on multivariate analysis. The total pregnancy rate was 47%, and the live birth rate was 40.1%. Patients who received infertility treatments showed a higher live birth rate (50.6%) than those who did not (7.7%). Conclusion In this survey, we confirmed that FS treatment in Japan is centered on MPA alone and in combination with metformin, and that the treatment efficacy is similar to that reported in previous reports. A multicenter survey study in Japan showed FS treatment for young AEH and EC patients in compliance with the indications is feasible.

OBJECTIVE: The Japan Society of Gynecologic Oncology (JSGO) published the first practice guideline for endometrial cancer in 2006. The JSGO guideline evaluation committee assessed the effect of this guideline introduction on clinical practice and patient outcome using data provided by the Japan Society of Obstetrics and Gynecology (JSOG) cancer registration system. METHODS: Data of patients with endometrial cancer registered between 2000 and 2012 were analyzed, and epidemiological and clinical trends were assessed. The influence of guideline introduction on survival was determined by analyzing data of patients registered between 2004 and 2009 using competing risk model. RESULTS: In total, 65,241 cases of endometrial cancer were registered. Total number of patients registered each year increased about 3 times in the analyzed period, and the proportion of older patients with type II endometrial cancer rapidly increased. The frequency of lymphadenectomy had decreased not only among the low-recurrence risk group but also among the intermediate- or high-recurrence risk group. Adjuvant therapy was integrated into chemotherapy (p<0.001). Overall survival did not significantly differ before and after the guideline introduction (hazard ratio [HR]=0.891; p=0.160). Additional analyses revealed patients receiving adjuvant chemotherapy showed better prognosis than those receiving adjuvant radiation therapy when limited to stage I or II (HR= 0.598; p=0.003). CONCLUSION: It was suggested that guideline introduction influenced the management of endometrial cancer at several aspects. Better organized information and continuous evaluation are necessary to understand the causal relationship between the guideline and patient outcome.

OBJECTIVE: Although radiation therapy (RT) and concurrent chemoradiotherapy (CCRT) are the global standards for adjuvant therapy treatment in cervical cancer, many Japanese institutions choose chemotherapy (CT) because of the low frequency of irreversible adverse events. In this study, we aimed to clarify the trends of adjuvant therapy for intermediate/high-risk cervical cancer after radical surgery in Japan. METHODS: A questionnaire survey was conducted by the Japanese Gynecologic Oncology Group to 186 authorized institutions active in the treatment of gynecologic cancer. RESULTS: Responses were obtained from 129 facilities. Adjuvant RT/CCRT and intensity-modulated RT were performed in 98 (76%) and 23 (18%) institutions, respectively. On the other hand, CT was chosen as an alternative in 93 institutions (72%). The most common regimen of CT, which was used in 66 institutions (51%), was a combination of cisplatin/carboplatin with paclitaxel. CT was considered an appropriate alternative option to RT/CCRT in patients with risk factors such as bulky tumors, lymph node metastasis, lymphovascular invasion, parametrial invasion, and stromal invasion. The risk of severe adverse events was considered to be lower for CT than for RT/CCRT in 109 institutions (84%). CONCLUSION: This survey revealed a variety of policies regarding adjuvant therapy among institutions. A clinical study to assess the efficacy or non-inferiority of adjuvant CT is warranted.

The Great East Japan earthquake and tsunami disaster that occurred on March 11, 2011 seriously destroyed Japanese social activities the medical system included. We provided medical support to the damaged area, and mainly performed Oriental medicine. Traditional methods using physical diagnoses and the treatments with herbs, acupuncture, and massage were effective, where any infrastructure had suffered or any modern medical facilities had been destroyed. Acute phase infectious disease, common colds, and hypothermia were dominant. Allergies increased two weeks later, and there was much mental distress, and chronic pain symptoms one month later. We prescribed Kampo herbal medicines for common colds, hypothermia, allergies, and mental distress. Moreover, we also performed acupuncture and kneaded patients' body to reduce pain, stiffness, and edema. These treatments were effective for both physical and mental distress. Thus we believe that Oriental medicine is valuable in disaster situations.

Objective: Associations between hospital treatment volume and survival outcomes for women with 3 types of gynecologic malignancies, and the trends and contributing factors for high-volume centers were examined. Methods: The Japan Society of Obstetrics and Gynecology tumor registry databased retrospective study examined 206,845 women with 80,741, 73,647, and 52,457 of endometrial, cervical, and ovarian tumor, respectively, who underwent primary treatment in Japan between 2004 and 2015. Associations between the annual treatment volume and overall survival (OS) for each tumor type were examined using a multivariable Cox proportional hazards model with restricted cubic splines. Institutions were categorized into 3 groups (low-, moderate-, and high-volume centers) based on hazard risks. Results: Hazard ratio (HR) for OS each the 3 tumors decreased with hospital treatment volume. The cut-off points of treatment volume were defined for high- (≥50, ≥51, and ≥27), moderate- (20–49, 20–50, and 17–26), and low-volume centers (≤19, ≤19, and ≤16) by cases/year for endometrial, cervical, and ovarian tumors, respectively. Multivariate analysis revealed younger age, rare tumor histology, and initial surgical management as contributing factors for women at high-volume centers (all, p<0.001). The proportion of high-volume center treatments decreased, whereas low-volume center treatments increased (all p<0.001). Treatment at high-volume centers improved OS than that at other centers (adjusted HR [aHR]=0.83, 95% confidence interval [CI]=0.78–0.88; aHR=0.78, 95% CI=0.75–0.83; and aHR=0.90, 95% CI=0.86–0.95 for endometrial, cervical, and ovarian tumors). Conclusion Hospital treatment volume impacted survival outcomes. Treatments at high-volume centers conferred survival benefits for women with gynecologic malignancies. The proportion of treatments at high-volume centers have been decreasing recently.
