A 1-day-old girl born with a thin collodion membrane was found to have severe thrombocytopenia of 34,000 per microliter. The rare report of the perinatal-lethal subtype of Gaucher disease presenting as a collodion baby represented an explanation for both signs and we recommended early genetics investigation. In the ensuing week, NICU evaluation revealed fevers, bradycardia, hypotonia; labs showed transaminitis, hypoglycemia requiring a continuous glucose infusion; ultrasound discovered hepatosplenomegaly, mild ascites, echogenic kidneys, scoliosis, an atrial septal defect and dilated right ventricle.

Radiation exposure with repeated radiography required at follow-up poses serious health concerns for scoliosis patients. Although spinous process angle (SPA) measurement of spinal curvatures with ultrasound has been reported with promising results, an evidence-based account on its accuracy for translational application remains undefined. This prospective study involved 952 idiopathic scoliosis patients (75.7% female, mean age 16.7 ± 3.0 y, Cobb 28.7 ± 11.6°). Among 1432 curves (88.1%) detected by ultrasound, there was good correlation between radiologic Cobb angles measured manually on EOS (E_Cobb) whole-...

AbstractAdolescent idiopathic scoliosis (AIS) is a three-dimensional (3D) spinal deformity. Current practice uses the Cobb method to measure spinal severity on postero-anterior (PA) radiographs. This method may underestimate spinal deformity and exposes patients to ionizing radiation, increasing the risk of cancer. This paper reports a new 3D ultrasound method using the voxel-based reconstruction technique with bilinear interpolation to reconstruct a 3D spinal image and measure true spinal curvature on the plane of maximal curvature (PMC). Axial vertebral rotation (AVR) was measured on the 3D image and utilized to estimate...

The objective of this study was to test the reliability of sagittal spinal curvature measurements using 3-D ultrasound in patients with adolescent idiopathic scoliosis (AIS). Ultrasound spinous process angle (USSPA) and ultrasound laminae angle (USLA) were measured on sagittal ultrasound images, while the Cobb angle (XCA) was measured on sagittal X-ray images. Intra-class correlation coefficients (ICC) for the intra- and inter-observer variability, linear regression analysis and Bland-Altman method, including mean absolute difference (MAD), were investigated to evaluate the reliability and validity of the two ultrasound an...

AbstractBackground contextSerial X-rays are needed during the follow-up of adolescent idiopathic scoliosis. They are done every 6 or 3  months in cases of high risk of progression. Thanks to the advances in ultrasound techniques, deformity measurement systems free from ionizing radiations have been validated, although spinal surgeons did not use them routinely due to the need of special software.ObjectiveThe aim of our work is to assess the reproducibility and correlation of an ultrasound measuring system based on the positioning of the transverse processes.Study designProspective, single center, randomized, triple bl...

The aim of this study was to assess the intra- and inter-rater reliability/agreement of the lateral abdominal muscle (LAM) stiffness and thickness measurements at rest and during contraction and to determine the relationship between the superficial fat thickness and the LAM stiffness measurements. LAM stiffness and thickness were measured using supersonic shear wave elastography (SSI) in pediatric participants. The reliability of LAM stiffness and thickness measurements ranged from moderate to excellent.

Conclusion. A multimodal intraoperative anesthetic regimen incorporating ESP blocks was able to eliminate the need for postoperative opioid analgesia following posterior spinal fusion. surgery. This case report serves as proof-of-concept that this regimen may significantly improve pain trajectories and reduce opioid use in this patient population. Level of Evidence: 4

This study objectives were (1) to report the rates of anomalies of 10 organ systems in congenital scoliosis patients and (2) to determine whether the presence of a single organ system anomaly increases the rate of nonspinal organ system defects. Summary of Background Data: Intraspinal, cardiac, renal, and gastrointestinal anomalies have been reported to occur at higher rates in congenital scoliosis than the normal population. It is unknown whether the presence of 1 organ system defect increases the risk of nonspinal organ system anomalies. Methods: All patients diagnosed, evaluated in the outpatient setting, with con...
