Tension pneumocephalus following bariatric surgery: case report.

Bariatric surgery is an effective treatment for patients with idiopathic intracranial hypertension (IIH), a condition that is associated with skull base defects. A 55-year-old woman presented with symptoms of intractable nausea and vomiting, followed by headache and confusion two weeks after an elective laparoscopic vertical sleeve gastrectomy procedure. She had a presumed diagnosis of IIH and a remote history of CSF oto/rhinorrhea treated with a lumbar peritoneal (LP) shunt. Computed tomography (CT) scan of the head revealed tension pneumocephalus with midline shift and dehiscence of the tegmen. The patient underwent emergent craniotomy for decompression of the air-filled temporal lobe, clamping of the LP shunt, and repair of the skull base defect. Caution should be exercised in obese patients with a history of CSF leak secondary to a middle fossa skull base defect when being evaluated for bariatric surgery.

Neurologic Status on Presentation as Predictive Measurement in Success of Closed Reduction in Traumatic Cervical Facet Fractures.

BACKGROUND: Dislocations to cervical facets resulting from traumatic injury often lead to neurologic impairment and can be treated both surgically and in a closed manner. OBJECTIVE: We sought to evaluate the utilization of closed reduction in the initial management of bilateral facet dislocations over the past 10 years at our institution. METHODS: We retrospectively reviewed the charts of patients who experienced subaxial cervical facet injury within the Penn Health System between 1 June 2006 and 1 June 2016 to identify patients with bilateral jumped/perched facets. The neurologic injury was identified on the basis of the American Spinal Injury Association (ASIA) spinal cord injury score. Analysis of variance and 2-sample t-tests were used to compare continuous distributions, and chi-square tests were used to compare categorical distributions. RESULTS: We focused our analyses on patients who presented with bilateral jumped/perched facets with (ASIA A and B) or without (ASIA C, D, E) complete voluntary motor deficit and underwent attempted closed reduction. We found that the rate of successful closed reduction was significantly higher in incomplete motor deficits (5/5, P = 0.04, chi-square test) as compared with complete motor deficits (n = 2/11). CONCLUSION: Our results demonstrate a significant difference in the success rate of closed reduction in patients with good neurologic status on presentation (ASIA A or B), compared with those with poor neurologic status (ASIA C, D, and E). These results suggest that closed reduction should be attempted in patients with good motor examinations on presentation, whereas those with significant deficits may benefit from earlier surgical intervention.

Associated injuries in traumatic sternal fractures: a review of the National Trauma Data Bank.

Sternal fractures occur infrequently with blunt force trauma. The demographics and epidemiology of associated injuries have not been well characterized from a national trauma database. The National Trauma Data Bank was queried for patients with closed sternal fractures. The demographics were analyzed by age, gender, mechanism and indicators of anatomic and physiologic injuries. Types of commonly associated injuries were also determined. A total of 23,985 records were analyzed. Males accounted for 68.3 per cent and whites 70.9 per cent. Motor vehicle crash was the leading mechanism. More than 56 per cent had severe injuries based on Injury Severity Score (greater than 15) and 17 per cent with Glasgow Coma Score 8 or less. Crude mortality was 7.9 per cent. The majority (57.8%) and approximately one-third (33.7%) of the patients had rib fractures and lung contusions, respectively, 22.0 per cent with closed pneumothorax, 21.6 per cent had a closed thoracic vertebra fracture, 16.9 per cent with lumbar spine fracture, 3.9 per cent with concussion, and blunt cardiac injury in 3.6 per cent. Sternal fractures are usually associated with severe blunt trauma. Lung contusion remains the leading associated injury followed by vertebral spine fractures. Cardiac injuries are less frequent and vascular injuries less so. Mechanism of injury and presence of sternal fractures should alert providers to these potential associated injuries.
