Perinatal infection is the leading cause of fetal and neonatal mortality and is directly related to childhood morbidity. Perinatal infections cause abnormal growth, delayed development, and many other clinical pro blems in newborns. In particular, TORCH syndrome can cause serious fetal and neonatal health problems through vertical infection, and timely diagnosis and treatment through regular antenatal examinations are important. There are no therapeutic options or vaccines for parvovirus or cytomegalovirus. Therefore, prevention is the most important method. In the case of toxoplasmosis, prenatal education is important because it can be prevented through hygiene management, although there are therapeutic drugs. Syphilis has a high preva­lence, so early diagnosis is important. Rubella and varicella zoster infections can lead to fatal results in vertical transmission to the fetus. Therefore, preconception vaccination should be performed.Women with herpes simplex, which has a high prevalence in the community, need to be mindful when choosing a childbirth method by evaluating the infection through regular prenatal care to prevent vertical infection. Seasonal flu is rarely transmitted vertically to the fetus, but the morbidity and mortality risk to the mother is higher than that of the general population. Thus, prevention through vaccination is important.Lastly, coronavirus disease 2019 (COVID-19) infection has yet to be well studied, although the mother's mor­bidity and mortality are similar to those of the general population and there is no evidence of vertical in­fection. Since the findings of the effects on the mother and fetus are limited, transmission should be pre­vented through social distancing and personal hygiene practices.

Objective: The purpose of this study was to evaluate the risk of osteopenia and osteoporosis by examining the bone mineral density (BMD) of the lumbar spine and femur in patients with gynecological cancer without bone metastasis and to evaluate the impact of treatment for different cancers on BMD. Methods: This study retrospectively reviewed the medical records of 243 women with gynecological cancer and 240 controls between March 2010 and December 2016. Patients with cervical cancer (n=105), endometrial cancer (n=63), and ovarian cancer (n=75) were treated with total hysterectomy including bilateral salpingo-oophorectomy and/or chemotherapy and/or radiotherapy. For the control group, healthy post-menopausal women without gynecologic cancer were selected. Results: Before anticancer treatment, the BMD of patients with cervical cancer and ovarian cancer was significantly lower than that of the controls, and the BMD of patients with endometrial cancer was not significantly different from that of the controls. However, the BMD of endometrial cancer significantly decreased after treatment. According to the treatment methods, there were significant differences in the BMD of L3, L4, and the femur neck. Changes in the BMD were lowest in patients who underwent surgical treatment only, and the highest bone loss was found in patients who underwent postoperative concurrent chemoradiotherapy. Conclusion Patients with cervical and ovarian cancer had lower BMD than those in the control group before treatment, and patients with endometrial cancer had decreased bone density after treatment. Therefore, during the treatment of gynecological cancer, strategies should be implemented to mitigate these risks.
