Reconstructing the frontal bone as an entire unit yielded excellent correction for coronal and metopic synostosis.”
“Erythropoietin is produced by the kidney and stimulates erythropoiesis;

however, in chronic renal disease its levels are reduced and patients develop anemia that is treatable with iron and recombinant hormone. The mechanism by which erythropoietin improves iron homeostasis is still unclear, but it may involve suppression of the iron regulatory peptide hepcidin Torin 2 and/or a direct effect on intestinal iron absorption. To investigate these possibilities, we used the well-established 5/6th nephrectomy rat model of chronic renal failure with or without human recombinant erythropoietin treatment. Monolayers of human intestinal Caco-2 cells were

also treated with erythropoietin Silmitasertib mouse to measure any direct effects of this hormone on intestinal iron transport. Nephrectomy increased hepatic hepcidin expression and decreased intestinal iron absorption; these effects were restored to levels found in sham-operated rats on erythropoietin treatment of the rats with renal failure. In Caco-2 cells, the addition of erythropoietin significantly increased the expression of apical divalent metal transporter 1 (DMT1) and basolateral ferroportin and, consequently, iron transport across the monolayer. Taken together, our results show that erythropoietin not only exerts a powerful inhibitory action on the expression of hepcidin, thus permitting the release of iron from reticuloendothelial macrophages and intestinal enterocytes, but also acts directly on enterocytes to increase iron absorption.

“BACKGROUND AND IMPORTANCE: This is the first report of using the superior lateral mass as an alternative starting point for C1 posterior screw placement,

demonstrating the importance of recognizing vertebral artery (VA) anomaly in deciding the surgical strategy for C1 screw placement.

CLINICAL PRESENTATION: A 56-year-old man presented with severe neck pain after a fall. Imaging demonstrated an unstable bursting fracture at Tyrosine-protein kinase BLK C4, C1-2 instability, and a subluxation at C2-3. Computed tomography angiography indicated that the persistent first intersegmental artery was located on the left side. The patient underwent anteriorposterior cervical fixation and fusion. Posterior C1 fixation was done with polyaxial screw rod construct using C1 superior lateral mass on the left side and C1 inferior lateral mass on the right side. The patient had no immediate postoperative deficits. At the 8-month follow-up examination, the patient was neurologically intact with a solid cervical fusion.
