Abstract
Perinatal spinal cord injury is a relatively uncommon, but a frequently misdiagnosed disorder. Improvements in obstetric care have certainly led to a decrease in the incidence of birth related spinal cord trauma but unfortunately the incidence of hypoxic-ischemic encephalopathy is still very high. The exact incidence of spinal cord trauma is difficult to determine because the spinal cord is not routinely examined in far and few neonatal autopsies done in India. Here, authors present a neonate who received treatment for birth asphyxia and then had extubation failure which made the clock tick towards cervical cord injury. This baby had a hemorrhagic contusion of cervical spinal cord.

Abstract
Background Neurodegenerative diseases such as Alzheimer’s are associated with the aggregation of endogenous peptides and proteins that contribute to neuronal dysfunction and loss. The glymphatic system, a brain-wide perivascular pathway along which cerebrospinal fluid (CSF) and interstitial fluid (ISF) rapidly exchange, has recently been identified as a key contributor to the clearance of interstitial solutes from the brain, including amyloid β. These findings suggest that measuring changes in glymphatic pathway function may be an important prognostic for evaluating neurodegenerative disease susceptibility or progression. However, no clinically acceptable approach to evaluate glymphatic pathway function in humans has yet been developed. Methods Time-sequenced ex vivo fluorescence imaging of coronal rat and mouse brain slices was performed at 30–180 min following intrathecal infusion of CSF tracer (Texas Red- dextran-3, MW 3 kD; FITC- dextran-500, MW 500 kD) into the cisterna magna or lumbar spine. Tracer influx into different brain regions (cortex, white matter, subcortical structures, and hippocampus) in rat was quantified to map the movement of CSF tracer following infusion along both routes, and to determine whether glymphatic pathway function could be evaluated after lumbar intrathecal infusion. Results Following lumbar intrathecal infusions, small molecular weight TR-d3 entered the brain along perivascular pathways and exchanged broadly with the brain ISF, consistent with the initial characterization of the glymphatic pathway in mice. Large molecular weight FITC-d500 remained confined to the perivascular spaces. Lumbar intrathecal infusions exhibited a reduced and delayed peak parenchymal fluorescence intensity compared to intracisternal infusions. Conclusion Lumbar intrathecal contrast delivery is a clinically useful approach that could be used in conjunction with dynamic contrast enhanced MRI nuclear imaging to assess glymphatic pathway function in humans.

Abstract
OBJECTIVE To report a multicenter study of nine cases of children presenting with a birth-related spinal injury. METHODS The medical charts of nine patients identified by a questionnaire sent to the members of the French Society of Pediatric Orthopedics (SOFOP) were reviewed. RESULTS The pregnancy was uneventful in all cases. The fetal presentation was cephalic in three cases, a breech presentation in four cases, and a face presentation in two cases. The lesion involved the cervical spine in six cases. Three patients presenting upper cervical injuries died before the age of six years. The six remaining patients experienced no neurological improvement. CONCLUSIONS These rare conditions occur during difficult deliveries with abnormal presentations, the most common being a breech presentation with entrapment of the fetal head. In a child with hypotonia, flaccid quadriplegia or high thoracic paraplegia after a difficult delivery, a spinal cord injury must be suspected and plain radiographs and MRI must be performed.

Abstract
Spinal cord injury is a rare occurrence that is often difficult to diagnose. This report describes a 2-year-old male with cervicothoracic spinal cord injury. The injury is thought to have occurred in the fetal period because the patient's thorax was markedly hypoplastic at birth and his mother had noticed a decrease in fetal movements for several weeks before the birth. The deep tendon reflex of the upper and lower extremities was absent at birth, as observed in other cases of spinal cord injury. It was noteworthy that deep tendon reflex of the upper and lower extremities remained decreased at 2 years of age despite the injury being located at C(7)-T(1). Based on this case, we propose that spinal cord injuries occurring in utero display different reflex responses from those occurring at birth.

Abstract
Spinal cord injury with or without trauma has been reported in the perinatal period. The prognosis depends primarily on diagnosis of the level, extent and nature of the lesion, established by correlations between clinical, imaging and electrophysiological data. A 25-day-old boy with normal birth weight delivered at term by cesarean section was transferred to Inönü University Turgut Ozal Medical Center because of respiratory distress and brachial diplegia. A suspicious medullary lesion on cervical computerized tomography was confirmed as an intramedullary lesion extending from C3 to D1 on magnetic resonance imaging (MRI). Emergent surgery consisting of exposure of the lesion site and interlaminar direct puncture of the lesion under fluoroscopy revealed that the pathology was an intramedullary hematoma. The partial evacuation of the lesion with direct puncture, the patient's neurological improvement and close follow-up of the patient with ultrasonography, electrophysiology and MRI are discussed in the light of recent literature.

Abstract
Neonatal upper cervical spinal cord injury is associated with rotational forceps delivery and presents with quadriparesis and diaphragmatic paralysis. The underlying pathology determines neurologic outcome but is difficult to assess clinically or with simple radiographic techniques. We report 4 cases in which early magnetic resonance imaging demonstrated the extent and severity of the injury and guided management.

Abstract
A term infant with normal delivery presented with congenital tetraplegia and respiratory insufficiency just after birth. Magnetic resonance tomography on days 8 and 72 of life revealed an extreme thinning of the lower medulla oblongata. Endoscopy confirmed this and demonstrated the presence of vascular anomalies around the lesion which were not detectable by angiography. It is presumed that this is a malformation of the lower medulla oblongata.

Abstract
This is the first case report on the diagnosis of spinal cord injury due to hemorrhage during the neonatal period using magnetic resonance imaging (MRI). Somatosensory evoked potentials are also helpful in the functional demonstration of this lesion. When discrepant signs, alert consciousness and intact cranial nerves are observed in newborn babies with flaccid extremities and respiratory disturbance, the immediate carrying out of MRI is mandatory in order to differentiate spinal cord injury from hypoxic-ischemic encephalopathy, cerebral hemorrhage, and neuromuscular disease.

Abstract
OBJECTIVES To establish criteria, evident soon after birth, that predict long-term outcome of neonates with spinal cord injury (SCI) at birth. DESIGN Retrospective case-series. SETTING Five Canadian regional neonatal tertiary care centers. PATIENTS Consecutive samples of patients referred to five centers for a total of 22 subjects, in whom SCI was diagnosed during life. Sites of lesions were above the fourth cervical vertebrae (n = 14), at the fourth cervical to the fourth thoracic vertebrae (n = 6), and at the thoracolumbar region (n = 2). MEASUREMENTS AND MAIN RESULTS All 14 patients with upper cervical SCI had cephalic presentations, whereas all 6 patients with cervicothoracic SCI had breech presentations (p < 0.0001). The site and extent of lesion were best diagnosed by clinico-imaging correlations. Ultrasonography appeared to be the most useful imaging study. In patients with upper cervical SCI who had no coexistent central nervous system abnormality associated with early death, long-term outcome in survivors (dependency on mechanical ventilation and on aids for upper limb activity and for ambulation) was best predicted by age when breathing was first observed and by rate of recovery of limb motor function in the first 3 months. The presence of breathing movements on day 1 (n = 2) was associated with mild disability. The absence of breathing movements on day 1 and little or no recovery of motor function in the first 3 months was associated with permanent total dependency on mechanical ventilation and severe quadriplegia (n = 5). Apnea on day 1 and intermediate recovery rates in the first 3 months was associated with variable long-term prognoses (n = 3).

Abstract
We investigated the somatosensory evoked potentials (SEPs) produced by posterior tibial nerve (PTN) stimulation in 8 infants and children with focal spinal cord disorders. The spinal responses of the PTN-SEPs were considered to assist in the localization of spinal lesions because their abnormalities were consistent with the neurologic and/or radiologic findings in all 6 examinations that revealed abnormal spinal SEPs. The cortical responses correlated significantly with proprioception in the lower limbs because proprioception was only disturbed when the cortical SEPs were absent (3 examinations). When both the spinal and cortical responses were abnormal, the spinal lesion probably involved the dorsal column so extensively that it completely interrupted the afferent impulses. In contrast, when SEP studies demonstrated abnormal spinal and normal cortical SEPs (3 examinations), the dorsal column involvement was probably less severe; therefore, both the spinal and cortical responses provided useful information regarding afferent conduction in the dorsal column. PTN-SEPs appear to have the potential to be of value in the diagnosis of focal spinal disease, especially in infants and young children who cannot cooperate with detailed neurologic examinations.

Abstract
After an uncomplicated pregnancy and delivery, this female child suddenly became quadriplegic on the fifth day of life. She gradually regained movement in her upper extremities. At 2 months of age, she exhibited paraplegia with exaggerated deep tendon reflexes in the lower extremities. Babinski reflex was present bilaterally and sensory disturbances below the trunk were suspected. Somatosensory evoked potentials after median and ulnar nerve stimulation revealed preserved conduction from the upper extremities through the cervical spinal cord to the cortex. Somatosensory evoked potentials after posterior tibial nerve stimulation suggested disturbed conduction in the upper thoracic spinal cord. Magnetic resonance imaging disclosed a hypodense area in the thoracic cord between T1 and T4 on both the T1-weighted and gradient echo images consonant with an old hematoma cavity. Digital subtraction angiography failed to demonstrate any vascular malformation.
