Cervical Spinal Cord Injury During Prone Position Ventilation in the COVID-19 Pandemic

The prone positioning of patients experiencing acute respiratory distress syndrome (ARDS) due to coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been proven effective in optimizing oxygenation and lung function. However, such patients may be at risk of developing complications due to the prolonged prone position in intensive critical care. A 45-year-old COVID-19 female, not known with cervical spine disease, presented with progressive severe COVID-19-related hypoxemia that required intensive care unit admission for pulmonary care. She was positioned prone and ventilated for several weeks. She developed a rapidly advanced decreased level of consciousness and flaccid quadriparesis. CT and MRI scans of the cervical spine revealed C4/C5 fracture-dislocation with spinal cord compression in asymptomatic ankylosing spondylitis and focal ossification of a posterior longitudinal ligament. In addition, the patient had severe ARDS-SARS-CoV-2 hemodynamic instability. Surgery was not performed due to her critical condition, and the patient died from multi-organ failure. Patients with underlying cervical spine disease or deformity can be subjected to hyperextension and develop fatigue (stress) spinal fracture, leading to spinal cord compression. To our knowledge, this is the first case of spontaneous cervical spine fracture dislocation in a COVID-19 patient after several weeks in prone position ventilation in ICU. Hence, our case report raises the awareness of the possibility of devastating spinal cord injuries in prone position ventilation during the COVID-19 pandemic and the need for early screening using plain X-rays of these patients for cervical spine disease.

Awake craniotomy. A patient`s perspective

Objective:

To report the personal experiences of patients undergoing awake craniotomy for brain tumor resection.

Methods:

We carried out a qualitative descriptive survey of patients’ experiences with awake craniotomies for brain tumor resection. The survey was conducted through a standard questionnaire form after the patient was discharged from the hospital.

Results:

Of the 9 patients who met the inclusion criteria and underwent awake craniotomy, 3 of those patients reported no recollection of the operation. Five patients had auditory recollections from the operation. Two-thirds (6/9) reported that they did not perceive pain. Five patients remembered the head clamp fixation, and 2 of those patients classified the pain from the clamp as moderate. None of the patients reported that the surgery was more difficult than anticipated.

Conclusion:

Awake craniotomy for surgical resection of brain tumors was well tolerated by patients. Most patients reported that they do not recall feeling pain during the operation. However, we feel that further work and exploration are needed in order to achieve better control of pain and discomfort during these types of operations.

Prevalence of the foramen arcuale of the atlas in a Saudi population

OBJECTIVE

To describe the prevalence and morphologic characteristics of the foramen arcuale of the atlas vertebra in the Saudi population and propose a simplified classification system.

METHODS

A cross-sectional hospital-based study was conducted at King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia from September 2010 to February 2011. During the 6-month period, 453 CT studies of the cervical spine were evaluated for the presence of different degrees of this anatomic variant using a clinically relevant classification system.

RESULTS

We found 52.1% (236 patients) to have no degree of osseous bridging, 31.8% (144 patients) had some degree of incomplete posterior osseous bridging, and 16.1% had the complete form of the foramen arcuale. The anomaly showed a male predilection that only reached statistic significance for those on the left side (p=0.016). Patients with a well-developed variant were older than those without the anomaly, but only by 7.46 years (p=0.034). These anomalies showed a propensity for bilaterality, which is a source for concern (kappa=0.592, approximate significance=0.00).

CONCLUSION

Compared to data from other countries, this anomaly has a higher prevalence in our population, indicating that further investigations are needed.
