Normal anterior-posterior diameters of the spinal cord and spinal canal in healthy term newborns on sonography.

Background: There are no published normal values for spinal cord and canal diameters in newborns. Spinal cord and spinal canal diameters are assessed subjectively by radiologists without any objective values for the upper limit of normal.

Objective: To determine normal values for anteroposterior (AP) diameters of the spinal cord and spinal canal on sonography in healthy term newborns.

Single-incision technique for tunneled central venous access.

Purpose: To describe the authors' experience in using a single-incision technique for placing implantable chest ports and tunneled dialysis catheters.

Materials And Methods: Implantable chest ports and tunneled dialysis catheters were placed in 130 consecutive unselected patients aged 18 to 81 years over a 6-month period. A micropuncture needle bent into a C shape was used to access the internal jugular vein (IJV) from an infraclavicular access under real-time ultrasonographic (US) guidance.

De novo placement of a tunneled dialysis catheter over a wire with the single-incision technique.

The authors describe a technique for the de novo placement of a tunneled dialysis catheter (TDC) over a wire. With use of a micropuncture needle bent into a C shape, the internal jugular vein was accessed under real-time ultrasonographic guidance from the expected catheter exit location in the deltopectoral fossa. The TDC was placed over the wire alone, without the use of a peel-away sheath.

Progressive Bronchiectasis as a Manifestation of Chronic Graft Versus Host Disease Following Bone Marrow Transplantation.

We describe a case of progressive bronchiectasis resulting in cystic bronchiectasis with regions of mucoid impaction as a manifestation of chronic graft versus host disease as a late complication of allogeneic bone marrow transplantation.
