Pediatric procedural sedation by a dedicated nonanesthesiology pediatric sedation service using propofol.

Objectives: To evaluate the success and dosing requirements of propofol in children for prolonged procedural sedation by a nonanesthesiology-based sedation service.

Methods: The pediatric sedation service at this institution uses propofol as its preferred sedative, and the local guideline suggests using 3 mg/kg for induction and 5 mg kg(-1) h(-1) for maintenance sedation. Doses can be adjusted as needed to individualize successful sedation.

Von Hippel-Lindau (VHL) disease: an update on the clinico-pathologic and genetic aspects.

von Hippel-Lindau (VHL) disease is an inherited multisystem familial cancer syndrome caused by mutations of the VHL gene on chromosome 3p25. A wide variety of neoplastic processes are known to be associated with VHL disease. The consequences of the VHL mutations and the pathway for tumor development continue to be elucidated.

Kawasaki disease: four case reports of cardiopathy with an institutional and literature review.

Kawasaki disease (KD) is a systemic vasculitis condition with a relatively unknown etiology. First described in 1967 by Tomisaku Kawasaki in Japan, KD has come to be widely diagnosed in every region of the world. The disease has a high prevalence in children ages 6 months to 5 years, particularly in those of Japanese descent.

E6 and E7 oncogene expression by human papilloma virus (HPV) and the aggressive behavior of recurrent laryngeal papillomatosis (RLP).

Recurrent laryngeal papillomatosis (RLP), a chronic disease associated with human papilloma virus (HPV), requires serial surgical procedures for debulking, resulting in debilitating long-term dysphonia, laryngeal scarring, and rarely malignant degeneration. Human papilloma virus 11 tumors have been widely accepted as more aggressive than HPV 6 tumors; however, the clinical course has been difficult to predict at disease onset, and the biologic mediators of proliferation have not been well characterized. A retrospective case review of 43 patients (4 months to 10 years at diagnosis) was performed on children treated for recurrent laryngeal papillomatosis.
