A uterocutaneous fistula is an abnormal tract between the endometrium of the uterus and the skin. It is a rare but significant postcesarean section complication. This is a case of a 39-year-old female who presented with cyclical bleeding from her cesarean section scar during menstruation over the past 4 years. The assessment revealed a discharging sinus in the scar and an acutely anteverted, fixed uterus. Symptoms persisted despite medical treatment for the provisional diagnosis of endometriosis. The diagnosis was updated as uterocutaneous fistula based on a computed tomography scan of the pelvis and abdomen and a hysterosalpingogram. The fistula was surgically excised, and a hysterectomy was performed. This report elaborates on the rare presentation, diagnosis, and definitive surgical management. The surgical management resulted in a successful resolution, highlighting the importance of choosing the appropriate treatment modality while adhering to a patient-centered approach.

A 40-year-old, gravida 3 para 2 (1-1-0-2), previous primary cesarean section for nonreassuring fetal status, presented at a tertiary hospital for confirmation of cesarean scar pregnancy (CSP). Transvaginal ultrasound confirmed a CSP at 8 2/7 weeks age of gestation with good embryonic cardiac activity, raising concern for early placenta accreta spectrum. A multidisciplinary team composed of an obstetrician, advanced pelvic surgeon, urologist, and anesthesiologist managed the patient. The patient underwent total abdominal hysterectomy with bilateral salpingectomy, as the patient has a completed family size. Before the procedure, she was given cefuroxime as prophylactic antibiotic. Intraoperatively, there were dense adhesions between the posterior bladder wall and the previous cesarean section scar. Inadvertent injury to the bladder wall was incurred during adhesiolysis. Cystorrhaphy was done by a urologist, while the rest of the surgery was unremarkable, with a 450 ml estimated blood loss. The postoperative course was unremarkable. Bladder rest was achieved by maintaining an indwelling Foley catheter, which remained in place upon discharge on postoperative day 3 and was continued for 7 days thereafter. At follow-up, a successful voiding trial was conducted, confirming the return of normal bladder function.

Ruptured Sinus of Valsalva (RSOV) is a rarely encountered cardiac anomaly that can potentially lead to adverse clinical outcomes. RSOV increases the risk of morbidity during pregnancy due to the physiological changes associated with gestation, that can exacerbate the underlying cardiac pathology. We present the case of a 29-year-old female with an uncorrected RSOV who required an emergency cesarean section for abruptio placenta. The patient underwent the procedure under spinal anesthesia, with careful titration of norepinephrine infusion and close monitoring of hemodynamic parameters using an invasive intra-arterial line. Given the absence of established anesthetic protocols for parturients with RSOV undergoing cesarean delivery, a comprehensive understanding of the complex interaction between the hemodynamic effects of RSOV, pregnancy, and anesthesia is essential. This understanding enables the safe use of spinal anesthesia in urgent situations, leading to favorable patient outcomes.

Objective: To investigate the clinical characteristics, treatments and fertility recovery of rudimentary horn pregnancy (RHP). Methods: The clinical data of 12 cases with RHP diagnosed and treated in Peking University Third Hospital from January 1, 2010 to December 31, 2022 were retrospectively analyzed. Clinical informations, diagnosis and treatments of RHP and the pregnancy status after surgery were analyzed. Results: The median age of 12 RHP patients was 29 years (range: 24-37 years). Eight cases of pregnancy in residual horn of uterus occurred in type Ⅰ residual horn of uterus, 4 cases occurred in type Ⅱ residual horn of uterus; among which 5 cases were misdiagnosed by ultrasound before surgery. All patients underwent excision of residual horn of uterus and affected salpingectomy. After surgery, 9 patients expected future pregnancy, and 3 cases of natural pregnancy, 2 cases of successful pregnancy through assisted reproductive technology. Four pregnancies resulted in live birth with cesarean section, and 1 case resulted in spontaneous abortion during the first trimester of pregnancy. No uterine rupture or ectopic pregnancy occurred in subsequent pregnancies. Conclusions: Ultrasonography could aid early diagnosis of RHP while misdiagnosis occurred in certain cases. Thus, a comprehensive judgment and decision ought to be made based on medical history, physical examination and assisted examination. Surgical exploration is necessary for diagnosis and treatment of RHP. For infertile patients, assisted reproductive technology should be applied when necessary. Caution to prevent the occurrence of pregnancy complications such as uterine rupture, and application of cesarean section to terminate pregnancy are recommended.

INTRODUCTION: There has been a global decrease in operative vaginal deliveries, with a marked shift towards the vacuum extractor. However, little is known about the trends in operative vaginal delivery in Singapore. METHODS: A retrospective study was conducted on all operative vaginal deliveries performed from 2012 to 2017 at Singapore General Hospital (SGH). Maternal outcomes in terms of postpartum haemorrhage and obstetric anal sphincter injuries were compared between forceps- and vacuum-assisted deliveries. Neonatal outcomes in terms of neonatal intensive care unit (NICU) admission and clinically significant neonatal events were compared. The instrument preference of obstetricians was analysed. RESULTS: A total of 906 consecutive operative vaginal deliveries were included in the study, comprising 461 forceps- and 445 vacuum-assisted deliveries. The rate of operative vaginal delivery was maintained at approximately 10% from 2012 to 2017. Neonatal cephalohematomas were more common after vacuum-assisted deliveries. Other maternal and neonatal outcomes did not differ significantly between the two groups. Clinically significant neonatal events were mostly due to shoulder dystocia, whereas all cases of NICU admissions were not directly related to the mode of delivery. Obstetricians' choice of instrument appeared to reflect personal preference and was not affected by the year of graduation. CONCLUSION The rates of neonatal and maternal morbidity were low at SGH. Overall instrument use of forceps and vacuum was balanced, and proficiency in both was demonstrated by all operators. Operative vaginal delivery remains an essential skill in facilitating safe vaginal delivery, which should be maintained to keep Caesarean section rates in check.

Objective: The objective of the study was to determine the effectiveness of myoinositol (MI) supplementation in the prevention of gestational diabetes mellitus (GDM) among high-risk patients. Materials and Methods: Comprehensive and systemic online searches were performed on PubMed, MEDLINE, Ovid, and Cochrane. Cross-referencing from related articles was also done. Only studies published in English were included in the study. We selected all randomized controlled trials on MI and singleton pregnant women with high risk for GDM. Data Collection and Analysis: Five randomized controlled trials were evaluated by two independent reviewers. For each comparison, the quality of evidence was assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Cochrane Collaboration tool. Review Manager 5.3 was used to generate the risk of bias evaluation and the analysis of the results. Main Results: The present study identified five randomized controlled trials involving 871 participants. The comparison of the studies showed a statistically significant reduction in the incidence of GDM in MI supplementation versus the control group (odds ratio [OR] = 0.32, 95% confidence interval [CI] = 0.19–0.53, P = 0.0001, Z = 4.36) by 68%. Similarly, there is a greater reduction in the incidence of fetal macrosomia among patients in the MI group than the controlled group (OR = 0.24, 95% CI = 0.07–0.78; P = 0.02, Z = 2.36) by 78%. However, there was no difference in terms of incidence of gestational hypertension (OR = 0.61, 95% CI = 0.19–2.01; P = 0.42, Z = −0.81), cesarean section (OR = 0.89, 95% CI = 0.65–1.22; P = 0.47, Z = 0.72), and neonatal hypoglycemia (OR = 0.35, 95% CI = 0.01–8.80; P = 0.53, Z = 0.63) outcomes. Conclusion MI supplementation taken at 4 g daily would decrease the incidence of GDM and fetal macrosomia. There was no statistically significant reduction in the risk of gestational hypertension, cesarean section, and neonatal hypoglycemia in the supplementation of MI.

Objective: To explore the risk factors of pulmonary hypertension (PH) in premature infants with bronchopulmonary dysplasia (BPD), and to establish a prediction model for early PH. Methods: This was a retrospective cohort study. Data of 777 BPD preterm infants with the gestational age of <32 weeks were collected from 7 collaborative units of the Su Xinyun Neonatal Perinatal Collaboration Network platform in Jiangsu Province from January 2019 to December 2022. The subjects were randomly divided into a training cohort and a validation cohort at a ratio of 8∶2 by computer, and non-parametric test or χ² test was used to examine the differences between the two retrospective cohorts. Univariate Logistic regression and multivariate logistic regression analyses were used in the training cohort to screen the risk factors affecting the PH associated with BPD. A nomogram model was constructed based on the severity of BPD and its risk factors,which was internally validated by the Bootstrap method. Finally, the differential, calibration and clinical applicability of the prediction model were evaluated using the training and verification queues. Results: A total of 130 among the 777 preterm infants with BPD had PH, with an incidence of 16.7%, and the gestational age was 28.7 (27.7, 30.0) weeks, including 454 males (58.4%) and 323 females (41.6%). There were 622 preterm infants in the training cohort, including 105 preterm infants in the PH group. A total of 155 patients were enrolled in the verification cohort, including 25 patients in the PH group. Multivariate Logistic regression analysis revealed that low 5 min Apgar score (OR=0.87, 95%CI 0.76-0.99), cesarean section (OR=1.97, 95%CI 1.13-3.43), small for gestational age (OR=9.30, 95%CI 4.30-20.13), hemodynamically significant patent ductus arteriosus (hsPDA) (OR=4.49, 95%CI 2.58-7.80), late-onset sepsis (LOS) (OR=3.52, 95%CI 1.94-6.38), and ventilator-associated pneumonia (VAP) (OR=8.67, 95%CI 3.98-18.91) were all independent risk factors for PH (all P<0.05). The independent risk factors and the severity of BPD were combined to construct a nomogram map model. The area under the receiver operating characteristic (ROC) curve of the nomogram model in the training cohort and the validation cohort were 0.83 (95%CI 0.79-0.88) and 0.87 (95%CI 0.79-0.95), respectively, and the calibration curve was close to the ideal diagonal. Conclusions: Risk of PH with BPD increases in preterm infants with low 5 minute Apgar score, cesarean section, small for gestational age, hamodynamically significant patent ductus arteriosus, late-onset sepsis, and ventilator-associated pneumonia. This nomogram model serves as a useful tool for predicting the risk of PH with BPD in premature infants, which may facilitate individualized early intervention.

OBJECTIVE: To investigate the effect of gastric antrum ultrasonography in evaluating gastric emptying after oral administration of 300 mL carbohydrates two hours before cesarean section, and to analyze the risk factors of gastric emptying in pregnant women. METHODS: From August 2020 to February 2021, a total of 80 patients, aged 22-43 years, body mass index (BMI) < 35 kg/m², gestational age≥36 weeks, falling into American Society of Anesthesiologists (ASA) physical status Ⅰ or Ⅱ, scheduled for cesarean sections in Peking University International Hospital were recruited and divided into two groups: the intervention group (n=40)and the control group (n=40). In the intervention group, solid food was restricted after 22:00, the patients were required to take 300 mL carbohydrates two hours before cesarean section. In the control group, solid food and liquid intake were restricted after 22:00 the night before surgery. All the patients received assessment of preoperative feeling of thirst and starvation with visual analogue scale (VAS). The cross-sectional area (CSA)of gastric antrum was measured in supine position and right supine position before anesthesia, the gastric volume (GV)and the gastric volume/weight(GV/W)of the two groups was further calculated. Perlas A semi-quantitative grading assessments were performed in each patient. The blood pressure and heart rate were recorded at admission(T0), 5 minutes after anesthesia (T1), immediately after fetal delivery (T2) and at the end of the surgery (T3). The occurrence of nausea and vomiting during the operation and 24 hours after the operation were recorded. RESULTS: One case in each group was excluded because the antrum was not clearly identified during the ultrasound assessments. In the semi-sitting position, the CSA was (5.07±1.73) cm² in the intervention group vs. (5.24±1.96) cm² in the control group, respectively; in the right lateral decubitus position, CSA was (7.32±2.17) cm² in the intervention group vs. (7.25±2.24) cm² in the control group, GV was (91.74±32.34) mL vs. (90.07±31.68) mL, GV/W was (1.27±0.40) mL/kg vs. (1.22±0.41) mL/kg, respectively; all the above showed no significant difference between the two groups (P > 0.05). Perlas A semi-quantitative grading showed 0 in 20 patients (51.3%), 1 in 16 (41%), 2 in 3 (7.7%)in the intervention group and 0 in 22 (56.4%), 1 in 15 (38.5%), 2 in 2 (5.1%)in the control group, the proportion of Perlas A semi-quantitative grading showed no significant difference between the two groups (P > 0.05). For the patients with Perlas A semi-quantitative grade 2 (3 cases in the intervention group and 2 cases in the control group), metoclopramide 0.2 mg/kg was intravenously injected before anesthesia. No aspiration case was observed in this study. The intervention group was endured less thirst and hunger (P < 0.05). There was no significant difference in blood pressure and heart rate between the two groups at each time point (P > 0.05). There was no significant difference in the incidence of intraoperative hypotension between the two groups (P > 0.05). There was no significant difference in the incidence of nausea intraoperatively and postoperatively between the two groups (P > 0.05). CONCLUSION Ultrasonography of gastric antrum can provide objective basis for evaluating gastric emptying of pregnant women perioperatively. 300 mL carbohydrates intake two hours before surgery, which does not increase GV and the risk of reflux aspiration, and is helpful in minimizing disturbance to the patient's physiological status, therefore leading to better clinical outcome.

Central nervous system involvement in primary Sjögren's syndrome (pSS) is less common and usually presents as white matter lesions, neuromyelitis optica spectrum disorder (NMOSD), or transverse myelitis. NMOSD is an immune-mediated inflammatory demyelinating disease of the central nervous system with a high rate of relapse and significant disability. Studies have shown that patients with pSS combined with NMOSD have more severe symptoms and poorer prognosis. Here, we present a case of critical illness in pregnancy-associated NMOSD combined with Sjögren's syndrome. The patient was a 30-year-old pregnant woman with a history of Sjögren's syndrome who was diagnosed with NMOSD. She received combination therapy with steroids, intravenous immunoglobulin (IVIG), and hydroxychloroquine during pregnancy, resulting in partial resolution of numbness below the waist. However, due to irregular medication adherence outside the hospital setting, she developed weakness in her right lower limb accompanied by inability to move it, while her left lower limb still had some mobility but occasional numbness along with urinary and fecal incontinence. Ten days later, she was admitted to the emergency department where an emergency cesarean section was performed to deliver a healthy baby boy. However, her condition worsened postpartum as she developed high fever accompanied by bilateral lower limb paralysis and weakness along with loss of voluntary control over urination and defecation. The patient underwent ano-ther course of treatment consisting of steroids and IVIG; however there was limited improvement in symptoms observed after this intervention. Following administration of rituximab for the first time, the patient developed urinary tract infection which was successfully managed before continuing regular infusions. In later stages the patient could walk slightly with a limp and regained control over urination and defecation, allowing her to resume normal activities. This case suggests that combination therapy with steroids, IVIG, and hydroxychloroquine should be considered for the patients with pregnancy-associated NMOSD combined with Sjögren's syndrome. Rituximab can significantly improve symptoms such as postpartum paralysis in patients with NMOSD, however, there may be a risk of infection associated with its use.
