RESUMEN
Over 80 % of ovarian cancer diagnoses are in women aged over 50 years. Post-menopausal women are at significantly increased risk compared with other age groups. Tumour biomarkers and ultrasound assist with diagnostics. A post-menopausal woman was referred with a possible left adnexal cyst on ultrasound. A tertiary gynaecological ultrasound suggested bilateral hydrosalpinges without cysts. Tumour markers were negative. Unexpectedly, while undergoing a laparoscopy, the tubes were normal in appearance; however, multiple cystic deposits suspicious for malignancy were noted on the ovaries. A laparoscopic bilateral salpingo-oophorectomy was performed without spillage and pelvic washings obtained. On histopathology, the ovaries contained multiple, benign epithelial cysts and pelvic washings were negative. This case demonstrates an unanticipated peri-operative diagnostic dilemma. It highlights the surgical management decisions required to balance duty of care and consent compliance within the scope of general gynaecology. It emphasizes the importance of histopathological examination to confirm diagnoses.
RESUMEN
OBJECTIVE: To evaluate the accuracy, clinical utility, and usability of a wireless fetal and maternal heartbeat monitor to monitor fetal heart rate (FHR). METHODS: We conducted a prospective, single-center study of a convenience sample of women aged 18 years or older with a singleton pregnancy of at least 12 weeks of gestation. Fetal heart rate recordings were performed using both the heartbeat monitor and cardiotocography to evaluate accuracy. Clinicians used the heartbeat monitor in the clinic. Women used the device, unassisted, during a clinic visit or at home. Obstetricians assessed the clinical utility of FHR traces. Women rated the heartbeat monitor using the System Usability Scale. RESULTS: A total of 81 participants provided 126 recordings. The accuracy of the heartbeat monitor was excellent compared with cardiotocography, with limits of agreement (95%) for mean FHR between -1.6 (CI -2.0 to 1.3) and +1.0 (CI 0.7-1.4) beats per minute (bpm), mean difference -0.3 bpm, intraclass coefficient 0.99. The FHR was detected on all occasions. Clinicians took a median (interquartile range) of 0.5 (0.2-1.2) minutes to detect the FHR, obtaining a continuous trace of longer than 1 minute in 95% (39/41) of occasions. Home users took a median of 0.5 (0.2-2.0) minutes to detect the FHR, obtaining a continuous trace of longer than 1 minute in 92% (24/26) of occasions, with a median total trace time of 4.6 (4.4-4.8) minutes. The traces were deemed clinically useful in 100% (55/55) of clinician and 97% (31/32) of home recordings. The heartbeat monitor ranked in the 96-100th percentile for usability and learnability. CONCLUSION: The heartbeat monitor was accurate and easy for clinicians and participants to use. Data recorded at home were equivalent to those obtained using current assessment protocols for low-risk pregnancies, potentially allowing the device to be used in telehealth consultations.
