Neonatal diagnosis of biliary atresia: a practical review and update.

Biliary atresia is challenging to diagnose because many of the clinical and imaging features of this condition overlap with those of other causes of cholestasis in newborns. When jaundice persists beyond 2 weeks of age, the neonate should be evaluated for cholestasis, and biliary atresia - the most common cause of neonatal cholestasis - should be considered. It is critical to diagnose biliary atresia early because failure to treat can result in hepatic fibrosis and death in less than 1 year.

Clinical utility and economic impact of routine delayed follow-up radiographs in children with uncomplicated distal radius Salter-Harris 2 fractures.

Background: Salter-Harris 2 fractures of the distal radius are common in pediatrics. Children with these fractures have a theoretical risk of developing a physeal bridge with subsequent growth disturbance.

Objective: The purpose of this study was to investigate the clinical utility and economic impact of obtaining routine delayed radiographs in asymptomatic patients with uncomplicated Salter-Harris 2 fractures of the distal radius.

A Case of Desmoplastic Small Round Cell Tumor.

Desmoplastic small round cell tumor is a rare, aggressive tumor primarily affecting young males. It is considered a childhood cancer, and is characterized by a unique chromosomal translocation which leads to failure to suppress tumor growth. It is classified as a soft tissue sarcoma, sharing some features with other small round cell tumors such as Ewing's Sarcoma and primitive neuroectodermal tumor.

Deforming lipoblastomatosis of the lower extremity.

Objective: Lipoblastomatosis is a rare disorder in infants and children and nonexistent in adults. We discuss a case of a newborn child with lipoblastomatosis extensively involving the pelvis and lower extremities. The clinical and radiological characteristics of the disorder are discussed.

Cervical spine geometry correlated to cervical degenerative disease in a symptomatic group.

Objective: To investigate whether a statistical correlation exists between lateral cervical geometry and cervical pathology, as identified on neutral anteroposterior (AP) and lateral radiographs within a symptomatic group; describe the cervical pathology and determine its location and frequency; and identify the subject's age, sex, and chief complaint.

Setting: Department of radiology at a chiropractic college.

Methods: One hundred eighty-six consecutive pairs of AP and lateral cervical radiographs were reviewed for pathology.

Clinical and radiological manifestations of the rheumatoid wrist. A comprehensive review.

Objective: The intent of this review article is to present the common clinical and radiological features of the rheumatoid wrist as seen in everyday practice. Imaging of the rheumatoid wrist is discussed with emphasis on magnetic resonance imaging (MRI) and its current and future role in the diagnosis and treatment follow-up of the disease.

Data Source: A search of the current medical literature from 1990 to present through PubMed was performed without constraints.

Dialysis-related spondyloarthropathy.

Objective: To discuss a case of dialysis-related spondyloarthropathy due to beta-2 microglobulin amyloid deposition. An emphasis is placed on the imaging findings.

Clinical Features: A 67-year-old man sought treatment for low back pain.

Tortuosity of the vertebral artery resulting in vertebral erosion.

Objective: To discuss the case of a patient with unilateral vertebral artery tortuosity and dilatation resulting in vertebral body and transverse foramen erosion. An emphasis is placed on diagnostic imaging.

Clinical Features: A 45-year-old man had a frozen shoulder and headaches.
