Artificial intelligence and visual inspection in cervical cancer screening.

INTRODUCTION: Visual inspection with acetic acid is limited by subjectivity and a lack of skilled human resource. A decision support system based on artificial intelligence could address these limitations. We conducted a diagnostic study to assess the diagnostic performance using visual inspection with acetic acid under magnification of healthcare workers, experts, and an artificial intelligence algorithm. METHODS: A total of 22 healthcare workers, 9 gynecologists/experts in visual inspection with acetic acid, and the algorithm assessed a set of 83 images from existing datasets with expert consensus as the reference. Their diagnostic performance was determined by analyzing sensitivity, specificity, and area under the curve, and intra- and inter-observer agreement was measured using Fleiss kappa values. RESULTS: Sensitivity, specificity, and area under the curve were, respectively, 80.4%, 80.5%, and 0.80 (95% CI 0.70 to 0.90) for the healthcare workers, 81.6%, 93.5%, and 0.93 (95% CI 0.87 to 1.00) for the experts, and 80.0%, 83.3%, and 0.84 (95% CI 0.75 to 0.93) for the algorithm. Kappa values for the healthcare workers, experts, and algorithm were 0.45, 0.68, and 0.63, respectively. CONCLUSION: This study enabled simultaneous assessment and demonstrated that expert consensus can be an alternative to histopathology to establish a reference standard for further training of healthcare workers and the artificial intelligence algorithm to improve diagnostic accuracy.

Twin pregnancy with Hydatidiform Mole and Co-existent Live Fetus: Lessons Learnt

This is a case report of a twin pregnancy with one fetus and a coexistent mole diagnosed at 13 weeks. After thorough counseling, the pregnancy was continued as per the patient’s desire. The pregnancy was closely monitored with serial S β hCG, ultrasound for fetal growth, size of molar sac, and theca lutein cysts, which gradually decreased in size during the second trimester of pregnancy. An emergency caesarean delivery was done at 36 weeks due to breech in early labour. A live baby weighing 1.8 kg was delivered in good condition. Her S β hCG reached normal levels at the end of three weeks, and she is now on post-molar surveillance. Though the general trend is to terminate pregnancy in twins with coexistent mole in anticipation of complications, under close surveillance, optimal outcomes can be achieved. Monitoring of S β hCG, serial ultrasound for fetal growth, size of molar component, and theca lutein cysts can help to predict good patient outcomes.
