RESUMEN
To examine whether patterns, such as the timings of onset or recovery from sleep disturbance, are associated with later developmental problems, including autism spectrum disorder (ASD). Mothers participating in the Japan Environment and Children's Study with a child aged 3 years were included in the analyses. Children were assessed for short sleep and frequent awakenings at 1 month, 6 months, and 1 year of age. Developmental problems were evaluated at 3 years of age based on ASD diagnosis and developmental delay, using the Japanese translation of the Ages and Stages Questionnaire (ASQ) 3rd edition. Sleep disturbance patterns were classified by onset age, and developmental problem risks were examined based on onset/recovery ages. Among 63,418 mother-infant dyads, 0.4% of infants were later diagnosed with ASD, and 14.4% had abnormal scores on any ASQ domains. The later the onset of short sleep, the lower the risk of abnormal ASQ scores (RR of short sleep onset at 1 year: 1.41; 6 months: 1.52; 1 month: 1.57). The earlier the infants recovered from short sleep persistence, the lower the risk of developmental delay (RR of remittance of sleep problems identified at 1 month by 6 months: 1.07; 1 year: 1.31; not before 1 year: 1.57). Although not all patterns were significant, later short sleep onset and earlier recovery were associated with lower ASD risk. These findings may have significant implications for future interventions in infant development.

INTRODUCTION: Herlyn-Werner-Wunderlich syndrome (HWWS) is characterized by uterine didelphys, unilateral cervical obstruction, and ipsilateral renal defects. Owing to its rarity, no standard surgical approach exists. PRESENTATION OF CASE: An 11-year-old girl with severe dysmenorrhea had a duplicated uterus, a right cervical hemorrhagic cyst, and right ipsilateral kidney agenesis, indicative of HWWS. As transvaginal surgery was challenging, we turned to laparoscopic surgery for abdominal cavity inspection and surgical assistance. A longitudinal incision was made on the right uterus, followed by inserting a catheter tube fixed to an intrauterine device (IUD) into the right cervical canal from the anterior wall of the right uterine horn. Subsequently, the right external cervical os was inverted to prevent restenosis. Postoperatively, the hemorrhagic cyst at the right cervix disappeared. The patient had no symptom recurrence 24 months after the surgery. DISCUSSION: The preoperative diagnosis for female genital malformations is complicated, and transvaginal manipulation is often difficult in adolescent girls. Laparoscopy is a valuable tool for evaluating female genital malformations, allowing for a thorough diagnosis and safe surgical treatment. In cases of female genital malformation with cervical obstruction, as in this case, reconstruction of the uterine cervix is important to prevent restenosis after surgery. CONCLUSION: In female genital malformations, laparoscopy provides a comprehensive evaluation of the malformation, assisting in a precise diagnosis and safe surgical treatment. Insertion of the catheter tube with IUD into the uterus and reconstruction of the cervix contribute to preventing restenosis.
RESUMEN
OBJECTIVE: In this study, we collected data over 8 years (2012-2019) from the Japan Society of Obstetrics and Gynecology (JSOG) tumor registry to determine the status of endometrial cancer in Japan, and analyzed detailed clinicopathological factors. METHODS: The JSOG maintains a tumor registry that gathers information on endometrial cancer treated at the JSOG-registered institutions. Data from the patients whose endometrial cancer treatment was initiated from 2012 to 2019 were analyzed retrospectively. RESULTS: A total of 82,969 patients with endometrial cancer underwent treatment from 2012 to 2019. Chemotherapy alone or in combination with hormonal therapy is more common among endometrial cancer patients under 40 years compared with those over 40 years. The number of patients with endometrial cancer, treated with laparoscopic or robot-assisted surgery was observed to have increased yearly. Small cell carcinomas and undifferentiated carcinomas were more likely to be diagnosed at an advanced stage. Lymphadenectomy was most commonly performed for stage IIIC2 disease, whereas positive peritoneal washing cytology was most common for stage IVB and serous carcinoma. CONCLUSION: Multi-year summary reports provided detailed clinicopathological information regarding endometrial cancer that could not be obtained in a single year. These reports were useful in understanding treatment strategies and trends over time based on age, histology, and stage.

BACKGROUND: The impact of parent-childbearing age on child development at 36 months of age is controversial. AIMS: We used data from a large cohort study with multiple imputation and mediation analyses of variables. METHODS AND PROCEDURES: A total of 72,606 parent-child pairs from the Japan Environment and Children's Study were included in the study. Parents' ages were categorized into five groups. We used five domains of the Japanese translation of the Ages and Stages Questionnaire, Third Edition (J-ASQ-3). Scores below the cutoff value at 36 months were defined as developmental delays in each domain. We used three logistic analysis models. In Model 3, we analyzed maternal and paternal age using other variables and covariates. OUTCOMES AND RESULTS: The outcome was a developmental delay in the five domains of J-ASQ-3. In Model 3, ORs for the developmental delay scores regarding parental age were significantly associated with all five domains of J-ASQ-3. The mediation analysis showed a significant mediation interaction effect for mothers but localized for fathers. CONCLUSION: Advanced paternal and maternal ages were associated with developmental delay in children. Awareness of the risks of childbearing at an advanced age is crucial. WHAT'S THE PAPER ADDS: This manuscript used data from a large cohort study with multiple imputation and mediation analyses. With these analyses, we identified the pure effect of advanced parental age on their children's development at 36 months.

Cytokine release syndrome (CRS) is a systemic inflammatory condition caused by an excessive immune response and cytokine overproduction. CRS is a life-threatening condition that is often associated with chimeric antigen receptor T-cell therapy. Despite the increased use of immune checkpoint inhibitors (ICIs), ICI-induced CRS remains rare. The present study describes a case of CRS that occurred after the administration of ICIs for recurrent adenocarcinoma of the uterine cervix. A 49-year-old woman received paclitaxel, carboplatin and pembrolizumab for recurrent cervical adenocarcinoma. On day 27 of the third cycle, the patient was admitted with a fever and suspected pyelonephritis. The following day, hypotension, upper respiratory symptoms and myalgia of the extremities were noted, and the left ventricular ejection fraction (LVEF) was decreased to 20%. Multiorgan failure (MOF) occurred, and the patient received ventilator support and continuous hemodiafiltration. Rhabdomyolysis, pancreatitis, erythema multiforme and enteritis were observed. CRS was diagnosed based on elevated ferritin and IL-6 levels. Steroid pulse therapy was administered; however, the MOF did not improve and the anti-IL-6-receptor monoclonal antibody tocilizumab (TOC) was administered. Subsequently, the LVEF improved to 50%, and the patient was removed from the ventilator on day 4 and from the continuous hemodiafiltration unit on day 6 after TOC administration. The patient was discharged on day 21. In conclusion, considering that ICI-induced CRS is a rare but severe complication, fever and other systemic conditions following ICI administration should be monitored.
RESUMEN
BACKGROUND: Lifelong health is dependent on prenatal growth and development, influenced by the placental intrauterine environment. Charged with dual functions--exchange of oxygen and nutrients as well as a barrier against toxins--the placenta itself is susceptible to environmental exposure to heavy metals. OBJECTIVE: To examine the use of placenta weight as a biomarker for heavy metal exposure using a large Japanese cohort of pregnant women. METHODS: The placenta weight, as a biomarker of exposure to heavy metals (cadmium, lead, and mercury), was investigated using data from the Japan Environment and Children's Study (2011-2014). Selenium and manganese were included as factors directly affecting fetal growth or heavy metal toxicity. Maternal blood samples collected in the second or third trimester were used to measure heavy metal concentrations. The association between maternal blood metal concentrations and placenta weight was explored by applying Z scores and multivariable logistic regression analysis and classifying participants into quartiles (Q1, Q2, Q3, and Q4) according to metal concentrations. RESULTS: This study included a total of 73,005 singleton pregnant women who delivered via live births and met the inclusion criteria. The median heavy metal concentrations in the maternal whole blood were 0.662 ng/g cadmium, 5.85 ng/g lead, 3.61 ng/g mercury, 168 ng/g selenium, and 15.3 ng/g manganese. Regression analysis revealed a significant correlation between placenta weight Z scores and maternal blood metal concentrations: cadmium, 0.0660 (standard error = 0.0074, p < 0.001); selenium, -0.3137 (standard error = 0.0276, p < 0.001); and manganese, 0.1483 (standard error = 0.0110, p < 0.001). CONCLUSION: This study provides a robust examination of the association between heavy metal exposure and placenta weight. Cadmium and manganese showed a positive correlation with significant differences, whereas selenium showed a negative correlation. Essential elements notably affect placenta weight differently. No significant association was noted between lead or mercury and placenta weight.

Syphilis infections discovered late in pregnancy, as in this case, may not be treated long enough for delivery. The Japanese guidelines should be revised because they do not describe the mode of delivery for pregnant women infected with syphilis.
RESUMEN
Robotic-assisted surgery enables precise manipulations with magnified vision, stereoscopic vision, and forceps with multi-joint functions. It requires unique procedures such as position setting, port placement, roll-in, and docking, which lead to prolonged operation and anesthesia time. Five conditions described below were established at our institution to reduce the time to the initiation of console: (1) changing the patients' position from the flat lithotomy position to the spread legs position; (2) attaching a Hasson cone to hold the umbilical cannula stable; (3) changing the cannula's obturator (inner tube) from blunt to bladeless; (4) fixing the team, and (5) conducting regular docking training. These outcomes were examined in this study. The study included 77 patients who underwent robotic-assisted total hysterectomy for benign uterine disease and stage IA uterine cancer at our individual institution between April 2019 and July 2022. We compared the median time from anesthesia to console initiation between the first half group (cases 1-40) and the second half group (cases 41-77). The former required 91.5 (53-131) minutes, whereas the latter required 59 (37-126) minutes. Appropriate equipment selection and team education can reduce the time to console initiation.

Adenocarcinoma, HPV-independent, mesonephric type (hereafter referred to as "mesonephric carcinoma") arising from the cervix is rare, its treatment has not been established, and its sensitivity to chemotherapy has not been fully investigated. Here we report on a 30-year-old female patient who presented at our hospital with a chief complaint of abnormal genital bleeding. We suspected cervical cancer. Based on examination, biopsy, and imaging, she was diagnosed with stage IIA2 adenocarcinoma of the cervix and was scheduled for surgery. Because she had a SARS-COV-2 infection, she was given two courses of paclitaxel-carboplatin (TC) therapy, based on the then-current surgical risk assessment after SARS-COV-2 infection, with a waiting period of at least 8 weeks. The patient was deemed to have a partial response and was treated with paclitaxel and carboplatin, after which she was deemed to have a partial response and underwent total hysterectomy. A diagnosis of stage IIA2 mesonephric carcinoma, ypT1b2N0M0, was made after histopathologic examination of an excised specimen. The patient was treated with 4 additional courses of TC therapy after surgery, and has had no recurrence in 13 months. We report a first case of response to neoadjuvant chemotherapy with TC regimen in a patient with mesonephric carcinoma of the cervix.

OBJECTIVE: Uterine tumours resembling ovarian sex cord tumours (UTROSCTs) are extremely rare. To date, most patients with UTROSCTs have undergone hysterectomy and had a benign clinical course. Fertility-preserving surgery should be considered because some patients with UTROSCTs are aged < 40 years. This paper reviews the treatment and prognosis for patients with UTROSCTs, with a focus on fertility. METHODS: PubMed, MEDLINE and Scopus were searched systematically for case reports and case series of UTROSCTs published in English from inception to December 2022, and initial treatment and recurrence rates were compared. The following data were extracted: age; symptoms; initial therapy; metastasis at diagnosis; disease-free survival (DFS); and recurrence. RESULTS: In total, 147 patients (72 studies) reporting the clinical course of UTROSCTs were analysed. The median age at diagnosis was 50 years, and 28 (19.0 %) patients were aged < 40 years. Most patients (n = 125, 85.0 %) underwent hysterectomy as the initial surgery, with a recurrence rate of 17.6 % (n = 22). The recurrence rate was 30 % (n = 6) in patients who underwent mass resection (n = 20). Among the 15 patients who underwent mass resection aged < 40 years, seven went on to achieve pregnancy (46.7 %) and six had successful deliveries (40.0 %). No significant differences in 5- and 10-year DFS were found between the hysterectomy and mass resection groups (p = 0.123 and 0.0612, respectively). Bilateral salpingo-oophorectomy in addition to hysterectomy was not significantly associated with 10-year DFS (p = 0.548). CONCLUSION: While total hysterectomy is the recommended treatment for UTROSCTs based on recurrence rates, mass resection is an acceptable treatment option for patients who wish to retain their childbearing potential. It is recommended that these women should plan for pregnancy and delivery as soon as possible after mass resection, and should undergo hysterectomy within 5 years.

The Japan Society of Gynecologic Oncology (JSGO) Guidelines 2022 for the Treatment of Uterine Cervical Cancer are revised from the 2017 guideline. This guideline aimed to provide standard care for cervical cancer, indicate appropriate current treatment methods for cervical cancer, minimize variances in treatment methods among institutions, improve disease prognosis and treatment safety, reduce the economic and psychosomatic burden of patients by promoting the performance of appropriate treatment, and enhance mutual understanding between patients and healthcare professionals. The guidelines were prepared through the consensus of the JSGO Guideline Committee, based on a careful review of evidence gathered through the literature searches and the medical health insurance system and actual clinical practice situations in Japan. The guidelines comprise seven chapters and 5 algorithms. The main features of the 2022 revision are as follows: 1) added discussed points at the final consensus meeting; 2) revised the treatment methods based on the International Federation of Gynecology and Obstetrics 2018 staging system; 3) examined minimally invasive surgery based on Laparoscopic Approach to Cervical Cancer trial; 4) added clinical question (CQ) for treatments of rare histological types, gastric type, and small-cell neuroendocrine carcinoma; 5) added CQ for intensity-modulated radiation therapy; 6) added CQ for cancer genomic profiling test; and 7) added CQ for cancer survivorship. Each recommendation is accompanied by a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here, we present the English version of the JSGO Guidelines 2022 for the Treatment of Uterine Cervical Cancer.

BACKGROUND: The influence of the coronavirus disease 2019 (COVID-19) pandemic on the number of newly diagnosed gynecological cancers has not been extensively investigated in Japan. This study determined the impact of COVID-19 on the incidence of gynecological cancer. METHODS: Using the Japanese Society of Obstetricians and Gynecologic Oncology registry database, the distribution of the number of patients based on clinical staging or tumor-node-metastasis classifications before and during the COVID-19 pandemic was analyzed to compare the trends. The clinical staging classification of cervical cancer in Japan was based on the International Federation of Gynecology and Obstetrics (FIGO) 2008 from 2018 to 2020 and on the FIGO 2018 from 2021. Since FIGO-2018 classified N1 cases as stage IIIC, we focused on T classification without referencing the clinical staging (FIGO staging) of patients with cervical cancer in 2021. RESULTS: The number of patients with endometrial cancer and malignant ovarian tumors of all clinical stages increased uniformly yearly, while that of those with stage III cervical cancer rapidly increased in 2021 owing to the adoption of the revised classification. On comparing cases of cervical cancer in 2020 and 2021, we found that T1 cases decreased and T2 and T3 cases increased in 2021 compared to those in 2020 (p = 0.006). Cervical intraepithelial neoplasia/adenocarcinoma in situ incidence decreased in 2020 compared to that in 2019 but increased again in 2021. The number of patients with cervical cancer decreased in most prefectures in 2020. CONCLUSION: The incidence of locally advanced cervical cancer increased during the COVID-19 pandemic.

Small-cell neuroendocrine carcinoma (SCNEC) of the cervix is a rare disease characterized by a high incidence of mixed tumors with other types of cancer. The mechanism underlying this mixed phenotype is not well understood. This study established a panel of organoid lines from patients with SCNEC of the cervix and ultimately focused on one line, which retained a mixed tumor phenotype, both in vitro and in vivo. Histologically, both organoids and xenograft tumors showed distinct differentiation into either SCNEC or adenocarcinoma in some regions and ambiguous differentiation in others. Tracking single cells indicated the existence of cells with bipotential differentiation toward SCNEC and adenocarcinomas. Single-cell transcriptional analysis identified three distinct clusters: SCNEC-like, adenocarcinoma-like, and a cluster lacking specific differentiation markers. The expression of neuroendocrine markers was enriched in the SCNEC-like cluster but not exclusively. Human papillomavirus 18 E6 was enriched in the SCNEC-like cluster, which showed higher proliferation and lower levels of the p53 pathway. After treatment with anticancer drugs, the expression of adenocarcinoma markers increased, whereas that of SCNEC decreased. Using a reporter system for keratin 19 expression, changes in the differentiation of each cell were shown to be associated with the shift in differentiation induced by drug treatment. These data suggest that mixed SCNEC/cervical tumors have a clonal origin and are characterized by an ambiguous and flexible differentiation state.

Myalgia is the most frequently reported neuromuscular symptom in COVID-19 patients, with a frequency of around 20% in pregnant women. Acute myositis due to COVID-19 is severe and requires medical intervention. There have been some reports of acute myositis due to COVID-19, mostly in elderly men, but rarely in pregnant women. Here we report a case of a pregnant woman who was diagnosed with acute myositis following COVID-19 illness early in her pregnancy. She had been affected by morning sickness since the 6th week of gestation and was diagnosed with COVID-19 at the 12th week. Muscle pain appeared in her limbs 5 days after the diagnosis of COVID-19, with a predominance of pain in the lower limbs, and her gait gradually became unstable. We concluded that it was acute myositis complicated by COVID-19 and hypokalemia, but we could not determine whether hypokalemia or COVID-19 or both were the cause of the muscle damage in this case. Pregnant women diagnosed with COVID-19 often complain of myalgia and fatigue, and when a pregnant woman's symptoms are severe we should keep in mind that they may be suffering from muscle damage that needs medical intervention.

AIM: To provide information including the trend of gynecological malignancies in Japan, we hereby present the annual patient report for 2020 and the Annual Treatment Report for 2015, on the outcomes of patients who started treatment in 2015. METHODS: The Japan Society of Obstetrics and Gynecology maintains an annual tumor registry, where information on gynecological malignancies from various participating institutions is gathered. The data of patients whose treatment with gynecologic malignancies was initiated in 2020 were analyzed retrospectively. Survival of the patients who started treatment with cervical, endometrial, and ovarian cancer in 2015 was analyzed by using the Kaplan-Meier, log-rank, and Wilcoxson tests. RESULTS: Treatment was initiated in 2020 for 7689 patients with cervical cancer, 13 113 with endometrial cancer, 8004 with ovarian, tubal, and peritoneal cancer, 2152 with ovarian borderline tumors, and with the others (260 vulvar cancer, 157 vaginal cancer, 464 uterine sarcoma, 50 uterine adenosarcoma, 136 trophoblastic diseases). This clinicopathological information was summarized as the patient annual report. The 5-year survival rates of the patients with cervical cancer were 92.3%, 76.2%, 56.5%, and 32.2% for Stages I, II, III, and IV, respectively. The 5-year survival rates for the patients with endometrial cancer were 93.9%, 87.6%, 71.4%, and 29.3% for Stages I, II, III, and IV, respectively. The 5-year survival rates for the patients with ovarian cancer (surface epithelial-stromal tumors) were 91.7%, 80.6%, 50.8%, and 39.7% for Stages I, II, III, and IV, respectively. CONCLUSION: The annual tumor report is an important survey that provides knowledge on gynecological malignancy trends in Japan.

BACKGROUND/AIM: Platinum-based drugs are the standard treatment for ovarian cancer, and platinum resistance is a major problem. A previous study has reported that the UBE2L6 expression is elevated in cisplatin-resistant cells, which in turn leads to cisplatin resistance by modulating the transcriptional expression of ABCB6. The present study aimed to investigate the expression of UBE2L6 and ABCB6 in ovarian carcinoma and to evaluate the association between these markers and platinum resistance. PATIENTS AND METHODS: Ninety-two patients diagnosed with serous ovarian carcinoma (SOC) were enrolled in this study. Tissue samples were collected from these patients and analysed using immunohistochemistry to assess the expression of UBE2L6 and ABCB6. RESULTS: UBE2L6 and ABCB6 staining was positive in 41 (44.6%) and 46 (50.0%) cases, respectively. UBE2L6 expression was statistically significantly associated with International Federation of Gynecology and Obstetrics (FIGO) stage (p=0.008). Both UBE2L6 and ABCB6 were significantly associated with platinum sensitivity (p<0.001 and p<0.001). A positive correlation was observed between the expression levels of UBE2L6 and ABCB6 (r=0.673, p<0.001). Progression-free survival (PFS) was significantly longer in the UBE2L6 negative group than that in the positive group (median PFS, 31.4 vs. 11.1 months, p<0.01) and in the ABCB6 negative group than that in the positive group (median PFS, 29.6 vs. 12.2 months, p<0.01). CONCLUSION: UBE2L6 and ABCB6 expression is associated with the prognosis of SOC. UBE2L6 and ABCB6 may be potential biomarkers of platinum-resistant ovarian cancer.

Most cases of tubo-ovarian abscess (TOA) are due to transvaginal infection, while other internal diseases may also be associated with TOAs. We experienced a case of ovarian clear cell carcinoma and rectal carcinoma that was discovered to be a result of TOA. A 46-year-old woman was diagnosed with TOA and referred to our hospital. Laparoscopic abscess drainage was performed, and pathological findings confirmed the presence of ovarian clear cell carcinoma inside the abscess. The tumor marker carcinoembryonic antigen (CEA) was elevated, and rectal cancer was diagnosed by a gastrointestinal endoscopy. Abdominal computed tomography (CT) showed a left adnexal abscess with an air image inside, and penetration of the abscess wall and rectal cancer were observed. Histopathologically, there was an accumulation of neutrophils around the rectal tumor cells. We concluded that the rectal cancer had penetrated the existing ovarian tumor and formed TOA. Non-gynecological diseases may be associated with TOA. It is necessary to consider the possibility that other clinical diseases may be associated with the trigger of TOA.

BACKGROUND/AIM: Small cell neuroendocrine carcinoma of the cervix (SCNEC) is a rare disease characterized by a higher incidence of lymphatic invasion, metastasis, and recurrence compared to the squamous cell carcinoma and adenocarcinoma subtypes. Furthermore, it is prone to early distant metastasis and has a poor prognosis. Chemotherapy has an important role in the management of cervical SCNEC. The effective treatment schemes for early-stage SCNEC are local treatment with radical surgery and systemic chemotherapy. However no standard treatment regimen exists because of a rare disease. We reviewed previous reports to determine whether etoposide/platinum, which is used for histopathologically similar small cell carcinoma of the lung, is an appropriate initial chemotherapy regimen for SCNEC of the cervix. MATERIALS AND METHODS: In this review the Cochrane library sources, ClinicalTrials.gov, Web of Silence, PubMed and search engine of Google scholar were searched for all interventional studies, reviews, case reports and meta-analyses published in 1997-2021. RESULTS: Etoposide/platinum (EP) is the most commonly used regimen and paclitaxel/carboplatin is the second most common, used as a part of multimodality therapy for SCNEC of the cervix in most studies. Cisplatin/vincristine/bleomycin, cisplatin/irinotecan, cisplatin/ifosfamide/etoposide were also reported in concurrence with EP; however no clinical trials are dedicated to SCNEC. CONCLUSION: Etoposide and platinum tend to have a better prognosis compared to other regimens used for other subtypes of cervical cancer. For recurrent cervical SCNEC, treatment options for patients are very limited. The application of molecular testing for targeted mutations may suggest potential future therapies that may be useful in this disease.

AIMS: Jarisch-Herxheimer reactions (JHR) is a transient adverse event that occurs during initial antimicrobial treatment for syphilis patients, and is known to develop uterine contractions and fetal distress in pregnant women complicated with syphilis. The aim of this study is to identify risk factors for JHR in patients with syphilis, and to clarify whether pregnancy status is a risk factor for JHR, and to describe the characteristics of pregnant women who develop JHR. METHODS: This was a retrospective chart review in a singleton university hospital in Japan. We collected data of syphilis patients who were diagnosed and treated at department of obstetrics and gynecology, dermatology between January 2010 and May 2022. There were no validated diagnostic criteria for JHR, we defined JHR as one or more of the following in addition to raised body temperature (â§38.0°C) within 24 h of initial antibiotic treatment: headache, chills, myalgias, tachycardia (â§110 bpm), new rash. RESULTS: There were 30 syphilis patients. Of whom nine (30%) were pregnant women and all their neonates were not diagnosed with congenital syphilis. Five patients (17%) developed JHR at the time of initial treatment (JHR group, n = 5). There was no difference between JHR group and non-JHR group (n = 25) in pregnancy status. Secondary syphilis was an only significant risk factor for JHR. Two pregnant women with JHR were both treated for secondary syphilis in the third trimester of pregnancy. CONCLUSION: Pregnancy status was not a risk factor for JHR in syphilis patients. Further research is needed.
