Pediatric mild head trauma: is outpatient follow-up imaging necessary or beneficial?

Objective: Pediatric traumatic brain injury (TBI) is the leading cause of death among children and is a significant cause of morbidity. However, the majority of injuries are mild (Glasgow Coma Scale score 13-15) without any need for neurosurgical intervention, and clinically significant neurological decline rarely occurs. Although the question of repeat imaging within the first 24 hours has been discussed in the past, the yield of short-term follow-up imaging has never been thoroughly described.

Adolescent Disc Disease: Risk Factors and Treatment Success-Related Factors.

Objective: A paucity of literature is available discussing the associated risk factors, treatment options (including the use of minimally invasive surgery), and outcomes related to lumbar disc herniation (LDH) in children. We have discussed the risk factors for disc disease among pediatric patients and evaluated the efficacy of the minimally invasive approach.

Methods: A retrospective review of pediatric patients with lumbar disc disease who had undergone microdiscectomy at our institution from 2005 to 2016 was conducted.

Incidentally found brain tumors in the pediatric population: a case series and proposed treatment algorithm.

Purpose: With the increasing use of imaging, there has been an increase in the number of incidentally found brain lesions in pediatric patients resulting in a treatment dilemma for physicians and emotional strain for patients and families. Adult studies support initial surveillance of incidentally found low grade appearing lesions as the most appropriate approach. The aim of this study was to evaluate incidental lesions in the pediatric population and propose an initial treatment algorithm for such lesions.

Management of hydrocephalus and subdural hygromas in pediatric patients after decompression of Chiari malformation type I: case series and review of the literature.

Objective: Hydrocephalus associated with subdural hygromas is a rare complication after decompression of Chiari malformation type I (CM-I). There is no consensus for management of this complication. The authors present a series of 5 pediatric patients who underwent CM-I decompression with placement of a dural graft complicated by posterior fossa hygromas and hydrocephalus that were successfully managed nonoperatively.

Early postnatal cranial vault reduction and fixation surgery for severe hydrocephalic macrocephaly.

OBJECTIVE Infants with severe hydrocephalus and extreme macrocephaly typically undergo CSF diversion early in life, which can result in significant cranial deformity due to CSF overdrainage. In this scenario, overlap of the cranial plates can precede the development of secondary synostosis and/or severe, permanent cranial deformity. As a result, extensive cranial vault remodeling is sometimes undertaken later in life, which is often challenging and has been associated with mortality and a high morbidity rate.

A Modified Technique for Occipitocervical Fusion Using Compressed Iliac Crest Allograft Results in a High Rate of Fusion in the Pediatric Population.

Background: In children, high rates of occipitocervical (OC) fusion have been demonstrated with the use of rigid instrumentation in combination with harvested autograft, with or without bone morphogenetic protein (BMP). Historically, the use of allograft materials demonstrated inferior OC fusion outcomes compared with autograft. However, autograft harvest harbors an increased risk of patient morbidity, and the use of BMP is costly and controversial in children.

Urological Outcome of the Xiao Procedure in Children with Myelomeningocele and Lipomyelomeningocele Undergoing Spinal Cord Detethering.

Purpose: Although previous studies have revealed high success rates (70% to 85%) after an intradural somatic-to-autonomic nerve transfer procedure in children with spinal dysraphism, no study has had a control group or blinded observers. We report a rigorously designed study to investigate the effectiveness of the Xiao procedure.

Materials And Methods: Children with neurogenic bladder dysfunction related to myelomeningocele or lipomyelomeningocele who required spinal cord detethering were randomized to 2 groups at surgery, with half undergoing only spinal cord detethering and half undergoing the Xiao procedure in addition to detethering.

Use of a contoured bioresorbable plate with a hemostatic plug to control life-threatening bleeding from the superior sagittal sinus during hemispherotomy: technical note.

Profuse bleeding originating from an injured cerebral sinus can be a harrowing experience for any surgeon, particularly during an operation on a young child. Common surgical remedies include sinus ligation, primary repair, placement of a hemostatic plug, and patch or venous grafting that may require temporary stenting. In this paper the authors describe the use of a contoured bioresorbable plate to hold a hemostatic plug in place along a tear in the inferomedial portion of a relatively inaccessible part of the posterior segment of the superior sagittal sinus in an 11-kg infant undergoing hemispherotomy for epilepsy.

Lack of efficacy of an intradural somatic-to-autonomic nerve anastomosis (Xiao procedure) for bladder control in children with myelomeningocele and lipomyelomeningocele: results of a prospective, randomized, double-blind study.

OBJECTIVE Xiao et al. and other investigators have studied an intradural somatic-to-autonomic (e.g.

Allograft versus autograft for pediatric posterior cervical and occipito-cervical fusion: a systematic review of factors affecting fusion rates.

OBJECT Fusion rates are high for children undergoing posterior cervical fusion (PCF) and occipito-cervical fusion (OCF). Autologous bone has been widely used as the graft material of choice, despite the risk of donor-site morbidity associated with harvesting the bone, possibly because very low fusion rates were reported with posterior allograft cervical fusions in children several decades ago. Higher overall fusion rates using allograft in adults, associated with improvements in internal fixation techniques and the availability of osteoinductive substances such as bone morphogenetic protein (BMP), have led to heightened enthusiasm for the use of bank bone during pediatric PCF.

Accidental intracranial infusion of parenteral nutrition in a preterm neonate.

Vascular access in the neonate can be challenging, especially in preterm infants. When other access is not available, superficial scalp veins can be safely used for vascular access. However, rare and potentially catastrophic complications can occur due to unique features of the neonatal skull and soft-tissue anatomy.

Attempted bladder reinnervation and creation of a scratch reflex for bladder emptying through a somatic-to-autonomic intradural anastomosis.

An intradural somatic-to-autonomic anastomosis, or Xiao procedure, has been described to create a "skin-CNS-bladder" reflex that improves bladder and bowel function in patients with neurogenic bladder and bowel dysfunction. The authors present their experience with a 10-year-old boy with chronic neurogenic bladder and bowel dysfunction related to spinal cord injury who underwent the Xiao procedure. After undergoing a left L-5 ventral root to left S2-3 intradural anastomosis, the patient reported that his bladder and bowel dysfunction improved between 6 and 12 months.

Pediatric microcystic meningioma: a clinical, histological, and radiographic case-based review.

Background: Microcystic meningioma (MM) is a World Health Organization grade I tumor that is rare in the pediatric population. Meningiomas account for approximately 2-4 % of all childhood central nervous system (CNS) tumors compared to approximately 20 % of all adult CNS tumors. The authors present one of the few confirmed cases of microcystic meningioma in a child and discuss the characteristic radiographic appearance and histological findings.

Cranial reduction and fixation with a resorbable plate combined with cerebrospinal fluid shunting for difficult-to-manage macrocephaly related to hydrocephalus.

The management of newborns with extreme macrocephaly related to hydrocephalus can be difficult; balancing the treatment of severe cranial deformity with optimal hydrocephalus management can be complicated. Excessive CSF drainage can result in significant suture overlap that leads to difficulties in patient positioning, secondary synostosis, and long-term aesthetic complications. Delayed cranial reduction and remodeling procedures carry significant risk, and the aesthetic outcomes have sometimes been poor.

Decompressive craniectomy with massive intractable intraoperative cerebral edema: utilization of silicone sheet for temporary scalp closure.

The authors present a case of extreme brain herniation encountered during decompressive craniectomy in a 21-month-old boy who suffered a trauma event that necessitated temporary scalp closure in which a sterile silicone sheet was placed. Although the clinical situation is usually expected to lead to brain death or severe disability, the patient's 3-year follow-up examination revealed a highly functional child with a good quality of life. The authors discuss the feasibility and advantages of temporary scalp expansion as a treatment option when extreme brain herniation is encountered during craniotomy.
