Increased cervical Chlamydia trachomatis and syphilis infections in Japanese females of reproductive age in the late 2010s: Possible cause.

Satoshi Shimano, Tasuku Mariya, Tsuyoshi Saito

Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy    2021.05  [International journal]

　View Summary

From 2000 to 2019, Japan's reproductive-age population gradually declined by 24%. In comparison, the Chlamydia trachomatis infection rate increased from 2016, with the syphilis infection rate increasing more sharply from 2014. Since 2013, the numbers of foreign tourists to Japan have also increased. From 2011 to 2018, the rate of increase in tourists was 5.02 times, while the rate of increase in syphilis patients was higher at 22.4 times. The lack of a one-to-one relationship between foreign tourists and syphilis cases suggests that cases of syphilis were transmitted to others. Although the prevalence of syphilis in the tourists' home countries (Korea in 2014 and China in 2013) was 20-30 times higher than that in Japan, the Japanese sex industry did not discriminate against foreign tourists, leading to increased STI infections in Japanese female sex workers. Indeed, from 2017 to 2018, a history of working in the sex industry for six months was identified as a risk factor for syphilis. The rise in Chlamydia trachomatis infections has lagged behind that of syphilis by two years, with the rate of increase lower. We suspect the difference in increasing rates of syphilis and chlamydial infections is due to the different methods of infection: syphilis can be transmitted by light physical contact, such as a kiss, whereas chlamydia requires close sexual contact, such as oral sex or sexual intercourse. Regardless, examinations and infection control are necessary to prevent the spread of STIs in Japan due to inbound tourists.

Does Radical trachelectomy (RT) during pregnancy have higher obstetrical and oncological risks than RT before pregnancy?

　View Summary

Purpose Radical trachelectomy (RT) with pelvic lymphadenectomy has become a new treatment option for young patients with uterine cervical cancer stages 1A2–1B1 who desire the preservation of their fertility. However, the application of RT for pregnant patients is still controversial. We comparatively studied both obstetrical and oncological outcomes of pregnant patients who underwent vaginal RT during pregnancy and those who underwent vaginal RT before pregnancy. Methods Both obstetrical and oncological results of eight patients who underwent vaginal RT with pelvic lymphadenectomy during pregnancy in our institute between 2010 and 2020 (Group A), and ten pregnant patients who underwent vaginal RT with pelvic lymphadenectomy before pregnancy during the same period (Group B) were reviewed based on their medical charts. Results There were no significant differences in blood loss, surgical time, or surgical completeness between Group A and Group B. Nor were there significant differences in obstetrical outcomes between the two groups. However, two of the eight patients in Group A had recurrence of the cancer. None of the patients in Group B has shown any signs of recurrence thus far. Conclusion Vaginal RT during pregnancy does not affect the obstetrical prognoses of patients with early invasive uterine cervical cancer, and it might be a tolerable treatment modality for them. However, oncologically, it should be performed carefully as there is a risk of recurrence.

　View Summary

Mismatch repair protein deficiency (dMMR) is a favorable prognostic factor in colorectal cancer. It is also associated with aberrant expression of HLA class I molecules, which are required for cytotoxic T lymphocyte-mediated cancer immunotherapy. Because dMMR is frequently also found in endometrial cancers (ECs), we retrospectively investigated the expression of mismatch repair proteins and HLA class I molecules in 127 EC patients. In this study, EC patients being treated in our hospital were recruited from 2005 to 2009 and observed until December 2017. Lesion specimens were evaluated via immunohistochemistry for MSH6 and PMS2 (mismatch repair proteins) and HLA class I molecules. Expression of these molecules was statistically related to clinical and pathological factors and prognosis. dMMR was detected in 33 patients and did not correlate with the expression level of HLA class I molecules (P = 0.60). On the other hand, unexpectedly, multivariate analysis revealed that intact expression of HLA class I molecules was associated with p53 overexpression (P = 0.004). Neither dMMR nor decreased expression of HLA class I molecules were prognostic factors. These results are inconsistent with previous findings for colorectal cancer. A distinctive local tissue immune microenvironment would underlie the discrepancy in the results between EC and colorectal cancer.

Common iliac artery dissection as a complication of common iliac artery balloon occlusion for placenta percreta: A case report.

Kimihito Saito, Tasuku Mariya, Yuya Fujibe, Masato Saito, Naoki Hirokawa, Shinichi Ishioka, Tsuyoshi Saito

The journal of obstetrics and gynaecology research   47 ( 3 ) 1172 - 1177  2021.03  [International journal]

　View Summary

A 37-year-old pregnant woman who had undergone three previous cesarean sections was diagnosed as having placenta percreta. We decided to perform cesarean hysterectomy with bilateral common iliac artery balloon occlusion (CIABO). The duration of surgery was 2 h and 2 min and total estimated blood loss was 2600 mL. Surgery was completed without any surgical complications, but the pulse oximeter waveform of the left leg became undetectable during surgery. We immediately performed angiography after closure of laparotomy and found abnormal pooling of contrast media at the left common iliac artery in the region in which the balloon was positioned. We made a diagnosis of left common iliac artery dissection caused by CIABO. We performed emergent revascularization by intravascular stenting. We conclude that CIABO can cause common iliac artery dissection by mechanical stimulation of the inflated balloon. Careful intraoperative evaluation of limb ischemia and preparation of intravascular treatment is needed for a safe procedure.
