Bilateral jumped facets dislocation in upper thoracic spine is rare injury because the thoracic spine is relatively immobile structure. We experienced a case of T2-3 dislocation without fracture and successfully reduced the dislocation after partial resection of the superior articular process of the third thoracic spine and performed fixation and fusion from T1 to T4 with pedicle screw system.

BACKGROUND: The current recommendation of rescue breathing techniques in the infant is to blow both the nose and mouth of infants by caregiver's mouth but recent studies suggest some caregivers may have trouble sealing a infant's mouth and nose. The purpose of this study is to estimate the ability of mothers to create a seal to their infants for the provision of rescue breathing according to current recommendation. METHODS: Infants up to 1 year of age(n=98) and their mothers were enrolled from emergency department of Chonbuk National University Hospital. We measured the facial lengths of the infants and the width of mouth in their mothers and compared mouth widths of mothers with their infant's nose-to-mouth lengths. RESULTS: In infants between 0 to 6 months, Mother transverse lengths were significantly larger than mouth, nose and nose-to-mouth lengths of the infants. In infants between 7 to 12 months, Mother transverse lengths were significantly larger than mouth and nose lengths of the infants but there was no statistically significant difference between mother transverse lengths and nose-to-mouth lengths of infants. CONCLUSION: The finding indicate that the present recommendation to cover mouth and nose is partly not possible. We recommend that the mouth-to-nose ventilation of rescue breathing techniques for the infants who have respiratory arrest be taught to mothers.

PURPOSE AND BACKGROUND: Recently several clinical studies suggested that maternal treatment with magnesium sulfate had protective effects against cerebral palsy in premature infants. But previous studies with differing perinatal animal models resulted in inconclusive results with regard to magnesium neuroprotection. Our purpose was to study the neuroprotective effect of magnesium sulfate and optimal dosage on hypoxicischemic brain damage in the newborn rat. METHOD: Seven-day-old rats(n=68) underwent right carotid ligation, followed by 3 hours of hypoxia(8% oxygen in 92% nitrogen). Rats received magnesium sulfate immediately before and again after hypoxia(two doses, 150mg-600mg/kg/dose, n=39), or saline solution(n=29). Severity of injury was assessed 5 days later, by visual evaluation of ipsilateral hemisphere infarction and by measurement of bilateral hemispheric cross sectional areas. RESULTS: Magnesium sulfate pre-treatment reduced the incidence of liquefactive cerebral infarction and atrophy from 80.8% in controls to 22.2% with magnesium sulfate(450 mg/kg/dose, P<0.05). Quantitation of hemispheric areas confirmed these findings. Percent protection based on inter-hemisphere area differences by pre-treatment with magnesium sulfate 450mg/kg/dose ranged from 71.1%(hippocampus) to 90.8%(striatum). However higher dose of magnesium(600mg/kg/dose) did not attenuate hypoxic-ischemic brain injury in the newborn rat but increased mortality. CONCLUSION: Pretreatment of magnesium sulfate has neuroprotective effects against hypoxia-ischemia in the newborn rat and adequate dose of magnesium sufate is important to protect the brain. Magnesium pretreatment may be an effective strategy to decrease the severity of neonatal hypoxic-ischemic brain injury in the adequate dose.
