Blunt bowel and mesenteric injuries in children: Do nonspecific computed tomography findings reliably identify these injuries?

Objective: Abdominal computed tomography has proven accurate for the detection of pediatric solid organ injuries following blunt abdominal trauma but is less reliable in detecting blunt bowel and mesenteric injuries (BBMI). The purpose of this study was to determine the significance of nonspecific findings on abdominal computed tomography (CT) scan in children at risk for BBMI.

Design: Retrospective chart review.

Chest radiography and the evaluation of the neonate for congenital heart disease.

We assessed the utility of the chest film as a screening tool for term and preterm neonates with suspected structural heart disease. Three independent observers, blinded to patient diagnosis, retrospectively evaluated the initial chest film for each of 128 consecutive neonates with suspected heart disease (gestational age, 23-42 weeks; birth weight, 500-4,621 g) who had undergone both chest radiography and echocardiography. These evaluations were subsequently compared with the results of the respective echocardiograms, read by board-certified pediatric cardiologists blinded to the chest film and chest film interpretation.

West Nile virus encephalitis with thalamic involvement in an immunocompromised child.

West Nile virus has been an increasingly important pathogen in the United States since it was first reported in 1999. Neuroinvasive West Nile virus has been infrequently reported in the pediatric population. We report a case of severe West Nile virus encephalitis with cranial magnetic resonance imaging findings not yet described in children.

Acute disseminated encephalomyelitis in childhood: epidemiologic, clinical and laboratory features.

Background: Acute disseminated encephalomyelitis (ADEM) is a central nervous system demyelinating disease that usually follows an apparently benign infection in otherwise healthy young persons. The epidemiology, infectious antecedents and pathogenesis of ADEM are poorly characterized, and some ADEM patients are subsequently diagnosed with multiple sclerosis (MS).

Methods: We retrospectively (1991-1998) and prospectively (1998-2000) studied all persons aged < 20 years diagnosed with ADEM from the 3 principal pediatric hospitals in San Diego County, CA, during 1991-2000.

Pneumococcal infection of the cavum septi pellucidi and cavum vergae in a pediatric patient.

The cavum septi pellucidi and cavum vergae are unusual sites of intracranial infection. A child is reported with infection of the cavum septi pellucidi and cavum vergae associated with pneumococcal meningitis. The patient required surgical drainage of the abscess despite appropriate antibiotic therapy, and the clinical outcome was excellent.

Detection of traumatic brain injury with magnetic resonance imaging and S-100B protein in children, despite normal computed tomography of the brain.

Objective: The objective of this study was to obtain data to further define the extent of traumatic brain injury by using S-100B protein and standard noncontrast magnetic resonance imaging with added fluid-attenuated inversion recovery (FLAIR) and gradient echo sequence in children with normal head computed tomography.

Design: Pilot, single cohort, prospective, clinical diagnostic study.

Setting: Pediatric intensive care and intermediate care unit in a tertiary care children's hospital.

Ceftriaxone-associated nephrolithiasis and biliary pseudolithiasis in a child.

Ceftriaxone is a widely used third-generation cephalosporin. It is generally very safe, but complications of biliary pseudolithiasis and, rarely, nephrolithiasis have been reported in children. These complications generally resolve spontaneously with cessation of the ceftriaxone therapy; however, they may symptomatically mimic more serious clinical problems, such as cholecystitis.

Risks for bacteremia and urinary tract infections in young febrile children with bronchiolitis.

Objective: To compare the risks for bacteremia and urinary tract injections (UTI) in young febrile children with and without bronchiolitis.

Design: A prospective cohort study.

Setting: The emergency departments of 3 pediatric referral hospitals.

Restricting the time of injury in fatal inflicted head injuries.

Objective: To determine the normal clinical progression of fatal head injuries in children. Such information can then be used to estimate the time of injury in cases with obscure histories and will thus aid investigations of nonaccidental trauma.

Method: A retrospective chart review design was used.

Hamartomas of the chest wall in infants.

Chest wall hamartomas in infancy are rare lesions with distinct clinical, radiologic, and pathologic characteristics. Four cases treated at Children's Hospital of Los Angeles are presented and previously reported cases are reviewed. Chest wall hamartomas arise antenatally and present as hard, immobile masses, which may cause respiratory insufficiency.

Clinical presentation and radiographic identification of small bowel rupture following blunt trauma in children.

The incidence of significant intraabdominal injuries from blunt trauma in children is low (1-8%); however, a missed intestinal laceration may result in a devastating, if not morbid, consequence. We present retrospective case studies of eight children with intestinal lacerations following blunt trauma. Each patient has a unique anatomic defect with misleading initial laboratory and radiographic studies.

Neuroblastoma masquerading as a retroperitoneal Salmonella abscess.

Symptomatic Salmonella infections usually manifest as self-limited gastrointestinal distress. Patients with chronic systemic illnesses or those who are immunosuppressed may rarely present with Salmonella infection as distant suppurative abscesses. We present a previously healthy Armenian boy who came to medical attention with abdominal pain, fever, and anemia.

New skeletal dysplasia with unique brachydactyly.

We report on 2 male propositi, their mothers, and a maternal aunt with a new skeletal dysplasia associated with a unique pattern of digital malformation, variable mild short stature, and mild bowleg with proximal overgrowth of the fibula. The digital malformations comprise a pattern of brachydactyly which includes short, abducted thumbs, short index fingers, and markedly short, abducted great toes. The radiographic findings include hypoplastic thumbs and great toes with short first metacarpals and first metatarsals, absent distal phalanges of the index fingers and second toes, and coalescence of the carpal and tarsal bones.

Malrotation of the intestine in children.

Intestinal malrotation may be complicated by volvulus and intestinal necrosis. One hundred two children (64 male, 38 female) undergoing surgical abdominal exploration from 1977 to 1987 had malrotation. Fifty-two patients were less than 7 days of age, 13 from 8 to 30 days, 26 from 31 to 365 days, and 11 were older than 1 year of age.

Pulmonary blastoma: a rare childhood malignancy.

Pulmonary blastoma is a rare primary malignancy of the lung, with few cases reported in children. The tumor consists of mesenchymal and epithelial components resembling the fetal lung. Seven children (aged 18 months to 5 years) with pulmonary blastoma were studied.

It may be more significant than you think: BB air rifle injury to a child's head.

BB guns of 20 years ago were constructed of coils and springs which generated relatively little force, so that a projectile posed little threat of serious injury. Today, the coil and spring construction has been replaced by pump action pneumatic chambers which allow generation of muzzle velocities near 350 ft/sec. Speeds of 150 ft/sec and 200 ft/sec are required for skin penetration and bone penetration, respectively.

Diagnostic aspects and syndromal associations of short trachea with bronchial intubation.

Conditions with disproportionately short trachea, with a reduced number of tracheal cartilage rings and a high level of tracheal bifurcation, have been reported. We have seen accidental bronchial intubation in nine patients with short trachea. This risk can be reduced by recognition of conditions associated with short trachea, by awareness that methods for calculating endotracheal tube length from body length can overpredict tube length for patients with short trachea, and when feasible, by use of preintubation chest roentgenograms showing air bronchograms to establish the thoracic level of tracheal bifurcation.

Incidence of short trachea in patients with myelomeningocele.

Short trachea, typically due to reduced tracheal cartilage ring number, produces high tracheal bifurcation which can be demonstrated in radiographs with evaluable air bronchograms. Accidental bronchial intubation with sequelae has been reported in short trachea patients who have tracheal intubation. Short trachea is associated with a number of syndromes, including DiGeorge anomaly and several types of congenital heart disease and skeletal dysplasias.

Acrocephalospondylosyndactyly--a possible new syndrome: analysis of the vertebral and intervertebral components.

Apert-Crouzon syndrome (formerly ACS type 2; 10130) is now considered a subset of autosomal dominant Apert acrocephalosyndactyly type 1 (10120), with features of craniosynostoisis, syndactyly of all extremities, maxillary hypoplasia, "parrot-beaked" nose, hypertelorism, exophthalmos, external strabismus, and short upper lip. We report a 3 1/2-month-old infant with features of Apert syndrome, plus thoracic vertebral anomalies radiographically similar to those seen in spondylothoracic dysplasia, a condition in which block thoracic vertebrae with widely open neural arches and a fan-shaped thoracic cage are found. Our patient also had flared metaphyseal ends of humeri, dislocated radii with immobile elbows, an unusual tail-like protuberance in the coccygeal area, and a solid cartilaginous tracheal wall.

Utility of the cervical spine radiograph in pediatric trauma.

To determine the utility of the routine cervical spine radiograph, we reviewed all cervical spine radiographs obtained in pediatric trauma patients over a 2 1/2-year period at the Childrens Hospital of Los Angeles. Records of patients admitted with a documented cervical spine injury over a 20-year period were also reviewed. One hundred eighty-seven children had at least one cervical spine radiograph.

Abdominal CT scanning in pediatric blunt trauma.

The use of the emergency IV contrast-enhanced abdominal computed tomography (CT) scanning was evaluated in 90 pediatric patients sustaining blunt abdominal trauma. Medical records, CT scans, and operative and postmortem reports, when applicable, were reviewed retrospectively. By identifying the organs of injury, CT scans of the abdomen, with IV contrast, proved to be useful to the surgeon in deciding whether to operate in the setting of blunt abdominal trauma.
