Background:Placenta adhesive disorder (PAD) is one of the most common causes of postpartum hemorrhage and peripartum hysterectomy. The main risk factors are placenta previa and prior uterine surgery such as cesarean section. Diagnosis of placenta adhesive disorders can lead to a decrease of maternal mortality and morbidities.Objective:The purpose of this study was to compare the accuracy of color Doppler ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of PADs.Materials and Methods:In this is cross-sectional study, Eighty-two pregnant women who were high risk for PAD underwent color Doppler ultrasound and MRI after 18 weeks of gestation. The sonographic and MRI findings were compared with the final pathologic or clinical findings. P<0.05 was considered statistically significant.Results: Mean maternal age was 31.42±4.2 years. The average gravidity was third pregnancy. 46% of patients had placenta previa. The history of the previous cesarean section was seen in 79 cases (96%). The diagnosis of placenta adhesive disorder was found in 17 cases (21%). Doppler sonography sensitivity was 87% and MRI sensitivity was 76% (p=0.37). Doppler sonography specificity was 63% and MRI specificity was 83% (p=0.01).Conclusion:Women with high-risk factors for PAD should undergo Doppler ultrasonography at first. When results on Doppler sonography are equivocal for PAD, MRI can be performed due to its high specificity.

Introduction: This study assessed the agreement of cone-beam computed tomography (CBCT) scan and sinus endoscopy findings and attempted to find a diagnostic accuracy of CBCT in patients with chronic rhinosinusitis (CRS). Methods: Forty-two patients with CRS referred to the Aria and 22 Bahman Hospitals in Mashhad, Iran, during the year 2011 were included in this cross-sectional study. Paranasal sinus CBCT scanning and endoscopy were performed in all patients. The sensitivity, specificity, positive and negative predictive values (PPV and NPV), and accuracy of CBCT were determined, and the agreement between CBCT and endoscopy findings was evaluated. Results: In most of our findings, except for infundibulum thickening, there was a strong agreement between CBCT and paranasal sinus endoscopy, with a kappa coefficient >0.80 (p < 0.05). The sensitivity, specificity, PPV, NPV, and accuracy of CBCT were >80% for most of the findings, except for infundibulum thickening and septal deviation. Conclusion: CBCT has nearly the same diagnostic accuracy as sinus endoscopy. The accuracy of CBCT scanning is high, and CBCT findings are well correlated with sinus endoscopy findings. Considering its high accuracy and lower costs and radiation doses, CBCT may be a proper alternative method for diagnostic sinus endoscopy in the assessment of CRS in patients with a contraindication for sinus endoscopy.

We describe a 20-year-old male patient who presented with gingival bleeding. Physical examination showed gingival swelling of the right maxilla and loosening of the molar teeth. The initial diagnosis of gingivitis was made, but further examination revealed a lytic lesion of the maxilla. On suspicion of fibrous dysplasia, biopsy was attempted but was unsuccessful due to severe haemorrhage. Further evaluation showed palpable and audible bruit on the gingiva, which caused the suspicion of vascular malformation. Angiography was performed and demonstrated arteriovenous malformation (AVM). Embolisation therapy with polyvinyl alcohol was performed. Post-embolisation angiogram demonstrated complete obliteration of the lesion.
