Determining scope position during colonoscopy without use of ionizing radiation or magnetic imaging: the enhanced mapping ability of the NeoGuide Endoscopy System.

Background: Knowledge of the position and shape of the endoscope could overcome many challenges of performing colonoscopy, e.g., loop formation.

Exclusion mapping of the genetic predisposition for cervical artery dissections by linkage analysis.

Skin biopsies from a patient with a dissection of the left internal carotid artery and from four of his children were analyzed by electron microscopy. The index patient and three children showed mild but regular electron microscopic connective tissue aberrations. They were considered as carriers of an unknown autosomal dominant mutation.

Intraperitoneal administration of recombinant human growth hormone in children with end-stage renal disease.

Recombinant human growth hormone (GH) therapy has been shown to be effective in the treatment of growth failure related to growth hormone resistance among children with chronic renal failure. The traditional route of administration is subcutaneous injection. This study was designed to evaluate the effectiveness and tolerability of intraperitoneal (i.

Recurrence of steroid-resistant nephrotic syndrome in kidney transplants is associated with increased acute renal failure and acute rejection.

We performed 73 kidney transplants in 51 patients with steroid-resistant nephrotic syndrome (SRNS) with focal segmental glomerular sclerosis (FSG) ages 18.4 +/- 12.8 (mean +/- SD) years.
