Average radiation dose with CT examinations was 1 mSv. Of the postoperative nonsubluxated hips (n = 30 for CT and n = 37 for MRI), CT demonstrated a sensitivity of 100% and a specificity of 96%, whereas MRI exhibited a sensitivity of 100% and a specificity of 100%. Of the postoperative subluxated

hips, 66.7% spontaneously reduced, 22.2% remained subluxated, and 11.1% redislocated.\n\nConclusions: This is the first study to compare these imaging modalities in the evaluation of hip reduction in DDH. This study affirms MRI as an alternative selleck to CT scan. The sensitivity and specificity of both modalities appears excellent. Similar to other studies, a large percentage of subluxated hips in both groups reduce without additional surgical intervention.\n\nLevel of Evidence: Diagnostic level II.”
“Objective: Currently, human chorionic gonadotropin (hCG) follow-up after evacuation of hydatidiform moles is essential

to identify patients requiring chemotherapeutic treatment for gestational trophoblastic neoplasia (GTN). We propose a model based on linear regression of postevacuation serum hCG concentrations for the prediction of GTN. Methods: One hundred thirteen patients with at least 3 AL3818 serum samples from days 7 to 28 after evacuation were selected from the Dutch Central Registry for Hydatidiform Moles (1994-2009). The slopes of the linear regression lines of the first 3 log-transformed serum hCG and free beta-hCG values were calculated. Receiver operating characteristic curves were constructed to calculate areas under curve (AUCs). Results: The slope of the hCG regression line showed an AUC of 0.906 (95% confidence interval, 0.845-0.967). Gestational trophoblastic neoplasia could be predicted in 52% of patients with GTN at 97.5% specificity (cutoff, -0.020). Twenty-one percent of patients with GTN

could be predicted before diagnosis according to the International Federation of Gynecology and Obstetrics 2000 criteria. The slope of free beta-hCG showed an AUC of 0.844 (95% confidence interval, 0.752-0.935), 69% sensitivity at 97.5% specificity, and 38% of patients with GTN could be predicted before diagnosis according to the International Federation of Gynecology and Obstetrics criteria. Conclusions: The slope of the linear regression line of hCG proved to be a good test to discriminate between patients who will achieve spontaneous disease remission and patients selleck screening library developing GTN. The slope of free beta-hCG seems to be a better predictor for GTN than the slope of hCG. Although this model needs further validation for different assays, it seems a promising way to predict the more aggressive cases of GTN.”
