Plexiform neurofibromatosis of the liver: an extremely rare case.

Herein, we report an extremely rare case of histopathologically proven neurofibromatosis of the liver. A 15-year-old male, a known case of type I neurofibromatosis (NF1), referred to our hospital with a complaint of right upper quadrant pain. He had a café-au-lait spot and positive family history of NF1 in his mother.

Intricate role of yes-associated protein1 in human liver cirrhosis: TGF-β1 still is a giant player.

Numerous investigations have been performed on the role of the transforming growth factor-β1 (TGF-β1) pathway in the development of chronic liver diseases (CLDs); however, they failed to explain the underlying mechanism of its pathogenesis, suggesting that other alternative pathways might have been overlooked. The involvement of yes-associated protein1 (YAP1) has been attributed to liver fibrosis; yet, the precise function of this protein has not been fully understood. Therefore, this study aimed to investigate the activity of the YAP1 pathway in human liver cirrhosis (regardless of its causality) and its correlation with the TGF-β1 and sonic hedgehog (SHH) pathways.

Value of Ultrasound in the Detection of Benign and Malignant Breast Diseases: A Diagnostic Accuracy Study.

Objectives: We sought to determine the diagnostic accuracy of ultrasound for benign and malignant breast lesions.

Methods: This retrospective study was performed to evaluate the diagnostic accuracy of ultrasound in 203 patients with complete medical records who visited Mehr Medical Imaging Center for breast ultrasound between March 2014 and February 2016. The collected data comprised of demographic characteristics, ultrasound results (consisting of the anatomic area of the lesion, the involved side, and the ultrasound characteristics of the lesion), mammogram results, and pathology reports (if surgery or biopsy was performed).

The ultrasound identification of fetal gender at the gestational age of 11-12 weeks.

Introduction: The early prenatal identification of fetal gender is of great importance. Accurate prenatal identification is currently only possible through invasive procedures. The present study was conducted to determine the accuracy and sensitivity of ultrasound fetal gender identification.

Comparison of allergic adverse effects and contrast enhancement between iodixanol and iopromide.

Background: Iodinated X-ray contrast media are the most commonly used contrast agents in the world with an annual application of 40-50 million. New non-ionic contrast agents are subdivided into low osmolar agents such as iopromide and iso-osmolar agents such as iodixanol. Regarding different biochemical characteristics, these agents are different in the allergic reactions and contrast enhancement and final lesion conspicuity.
