Spontaneous Unilateral Chiari I Secondary to Acquired Tonsillar Hypertrophy/Pseudomass With Syringomyelia in a Juvenile With Progressive Scoliosis.

Chiari type 1 malformation (CM-1) is a structural defect of the central nervous system in which part of the cerebellar tonsils descend below the level of the foramen magnum, sometimes with associated syringomyelia. Although Chiari malformations were traditionally believed to be congenital, several cases of acquired CM-1 with syringomyelia have been reported. Usually associated with repeat lumbar puncture, increased intracranial pressure, and craniocephalic disproportion, CM-1 in the absence of an underlying etiology is rare.

An Acute Nocardia Infection in a Pediatric Hand.

Nocardia species are aerobic gram-positive filamentous organisms that may cause cutaneous or pulmonary disease in humans. Primary cutaneous nocardiosis may manifest as an acute superficial pyogenic infection that can mimic more common organisms such as Staphylococcus or Streptococcus. Acute pyogenic Nocardia infection of the pediatric hand is a rare manifestation of this condition.

Plating of open pediatric tibia fractures.

This study is a single center retrospective chart and radiographic review of patients with open tibia fractures under the age of 16 years of age over past 10 years. The purpose of this study is to investigate the treatment of open pediatric tibia fractures with plating in regards to time to ambulation, time to union, and deformity in comparison to other treatment options. We found that plating open pediatric tibia fractures is a safe treatment option that can lead to excellent results with low risk of complications.

All-terrain vehicle injuries in children.

Purpose: All-terrain vehicles (ATVs) were introduced in the early 1970s. Injury rates in children and adolescents were alarming. The Consumer Products Safety Commission 2002 annual report revealed 5239 deaths attributed to ATVs between 1982 and 2002.
