Pediatric Sedation

Gadolinium-based compounds are frequently used in contrast-enhanced magnetic resonance imaging studies. Rarely, adverse events have been reported with administration of these compounds, of which the most common are nausea and vomiting. Although well established in the adult literature, these adverse effects are less well described in the pediatric population, who often need sedation to complete imaging studies. In this case series, we present 3 children who experienced vomiting shortly after contrast administration while under sedation with propofol, which is known to have antiemetic properties. Although all 3 children recovered without complication, this case series illustrates the serious potential consequences of vomiting while sedated, and providers should be aware of these possible adverse events as pediatric sedation becomes more common outside the operating room.

Background: Bone bruise characteristics after anterior cruciate ligament (ACL) injury have been correlated with the level of joint derangement in adults. However, the literature lacks information about younger patients, whose higher ligamentous laxity may lead to different lesion patterns. Purpose: To investigate the prevalence, size, location, and role of bone bruise associated with ACL rupture in the pediatric population. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Knee magnetic resonance imaging scans (MRIs) of patients aged 8 to 16 years with ACL tears from 2010 to 2018 were selected from the institution database. Inclusion criteria were open or partially open physes, less than 90 days between trauma and MRI, and no history of injury or surgery. Presence, localization, and size of bone bruise were analyzed by 2 blinded researchers and scored with the Whole-Organ Magnetic Resonance Imaging Score (WORMS) bone bruise subscale. Ligamentous, cartilaginous, meniscal, and other lesions were documented. Results: Of the 78 pediatric patients selected from the database, 54 (69%) had bone bruise. The mean area of bone bruise was larger in males than in females (femur, 3.8 ± 2.8 vs 2.2 ± 1.4 cm2, respectively, P = .006; tibia, 2.6 ± 1.6 vs 1.5 ± 0.8 cm2, respectively, P = .007). The subregions most affected by bone bruise were the lateral posterior tibia and the lateral central femur (in 83% and 80% of the knees affected, respectively). A low correlation was found between age and bone bruise area (biggest areas r = 0.30, P = .03, and sum of areas r = 0.27, P = .04), but no correlation was found between age and WORMS (femur, r = −0.03, P = .85; tibia, r = −0.04, P = .76). The injuries most associated with bone bruise were 23 meniscal lesions (43%), 10 lesions of other ligaments (19.0%), 2 cartilage lesions (3.7%), and 2 patellar fractures (3.7%). Conclusion: The prevalence of bone bruises in pediatric patients with ACL tears is high, although it seems slightly lower than the prevalence documented in adults but with similar localization. The area and the distribution pattern of bone bruises are similar among different ages. The pediatric patients had a lower presence of cartilage and meniscal lesions compared with that reported in adults, which suggests a different effect of this trauma on the knee of pediatric patients.

Mri Evaluation

The aim of this study was to analyze the added utility of contrast administration for spine MRI in children with scoliosis. A retrospective review of 663 consecutive contrast-enhanced spine MRI performed in 319 patients as part of the work up of scoliosis in children 2–18 years with clinically suspected or known scoliosis over a seven year period. Those patients with known tumors (13 patients) being evaluated for scoliosis were excluded from the study. In 306 patients with scoliosis and no history of tumor pathologic contrast enhancement was seen in seven (2%) patients. Lack of enhancement helped to characterize benign lesions in 31 (10%) of the patients. Although MRI is often recommended to exclude intraspinal pathology in pediatric patients with scoliosis, the need for contrast enhanced imaging is very limited and contrast medium should not be administered unless questionable pathology is detected on noncontrast MR spine imaging.

Background: Unsuccessful medical treatment of pyogenic multifocal spondylodiscitis including signs of sepsis and unremitting pain is challenging. The aim of our report was to present a case of multilevel spondylodiscitis successfully treated by posterior lumbar interbody fusion using porous tantalum cages.Case presentation: A 59-year-old male was diagnosed with spondylodiscitis at T8-T9 level. Although treated with antibiotics, the patient again presented with worsening of systemic signs of infection and back pain. Contrast-enhanced magnetic resonance imaging studies revealed spondylodiscitis at L1 to S1 level. Posterior lumbar interbody bone fusion with tantalum cages from L1 to S1 was performed. The inflammation rapidly subsided. Computer tomography studies showed a stable construct at 24 months.Conclusion: Porous tantalum cages used in combination with transpedicular fixation seem to be a sound alternative to interbody devices made from other materials when treating spondylodiscitis cases without definite osseous destruction.

Objectives: Manufacturers have introduced cochlear implants (CIs) with removable magnets to allow for magnetic resonance imaging after placement. The purpose of this study was to describe magnet displacement as a new CI complication and to suggest apossible treatment option to prevent its recurrence. Study Design: Retrospective case series. Methods: The records of 3 young males who experienced CI magnet dislodgement were reviewed and compared against records from the institutional implant database. Results: Magnet displacement was observed only in young males (14% of male children) who received CI with removable magnets. This occurred 13-14 months after CI placement. Magnets were replaced under general anesthesia, and the scalp was bolstered with a dermal allograft. Recurrent magnet dislodgement was encountered in 1 patient, 6 months later. Conclusions: Magnet displacement may be a relatively common complication after minor head trauma in pediatric patients with certain CIs that have removable magnets.

Amebic Encephalitis

Granulomatous amebic encephalitis (GAE) caused by Acanthamoeba is a rare infection with central nervous system (CNS) involvement usually with fatal consequences. Currently, information regarding GAE in children is scarce and is limited only to case reports and case series. A 13-year-old immunocompetent male patient with a 6-month history of progressive and intermittent headaches presented to our institution. One week before hospital admission, the patient showed signs of CNS involvement. Magnetic resonance imaging revealed multiple lesions with supra- and infratentorial cerebral abscesses. An empiric treatment with combined antibiotics was given, but the patient died after 20 days of hospital stay. A postmortem diagnosis confirmed GAE. Although it is a rare disease in pediatric patients, GAE should be considered in children with a chronic history of fever, headache, and vomiting with CNS involvement.
