Lumbar disk herniation in adults is thought to be caused by repetitive overloading and age-rated degenerative changes. However, these causes are absent in children and adolescent patients. We assume that structural malformations in the lumbar spine could predispose intervertebral disks to early degeneration and hence need to be surgically fused. This issue has never been raised before. ⋯ ICL, intercrestal lineLDH, lumbar disk herniationL5TP, L5 transverse processODI, Oswestry Disability IndexTV, transitional vertebraeVAS, visual analog scale.

Recreational use of small-wheeled vehicles (SWVs), which include skateboards, longboards, nonmotorized scooters, ice skates, and roller skates or rollerblades, results in numerous injuries in the United States. ⋯ ED, emergency departmentSWV, small-wheeled vehicleTBI, traumatic brain injury.

Protein levels in cerebrospinal fluid (CSF) are commonly thought to be related to sterile shunt malfunction. ⋯ In our laboratory setting, there was decreased resistance of adult CSF shunt catheters with and without a valve as the concentration of protein in the CSF increased. The decrease in the resistance of CSF shunt catheters with the addition of protein to the CSF may be related to the lowering of surface tension. This is the first study to examine the effects of varying protein concentrations across different lengths of shunt tubing for both new and explanted catheters.
