Objectives:To evaluate continuous positive airway pressure (CPAP) compliance and define predictors of CPAP compliance among Saudi patients with obstructive sleep apnea (OSA) after applying an educational program.Methods:This prospective cohort study included consecutive patients diagnosed to have OSA based on polysomnography between January 2012 and January 2014 in King Saud University, Riyadh, Kingdom of Saudi Arabia. All patients had educational sessions on OSA and CPAP therapy before sleep study, and formal hands-on training on CPAP machines on day one, day 7, and day 14 after diagnosis. The follow-up in the clinic was carried out at one, 4, and 10 months after initiating CPAP therapy. Continuous positive airway pressure compliance was assessed objectively. Logistic regression model was used to assess the predictors of CPAP adherence.Results:The study comprised 156 patients with a mean age of 51.9±12.1 years, body mass index of 38.4±10.6 kg/m2, and apnea hypopnea index of 63.7±39.3 events/hour. All patients were using CPAP at month one, 89.7% at month 4, and 83% at month 10. The persistence of CPAP-related side effects and comorbid bronchial asthma remained as independent predictors of CPAP compliance at the end of the study.Conclusion:With intensive education, support, and close monitoring, more than 80% of Saudi patients with OSA continued to use CPAP after 10 months of initiating CPAP therapy.
BACKGROUND A traumatic spinal fracture (TSF) is a serious condition that has a tremendous impact on patients and their families. Understanding the causes and patterns of TSF is critical in developing prevention programs. OBJECTIVES Identify causes and patterns of TSF and explore predictors of neurological disability in Saudi Arabia. DESIGN A retrospective medical record review. SETTING Level 1 trauma center in Riyadh. PATIENTS AND METHODS The analysis included all consecutive patients who met the inclusion criteria for any acute TSF in patients 18 years of age and older from January 2001 to January 2016. A multivariate logistic regression model was used to identify predictors of neurological disability following TSF. MAIN OUTCOME MEASURES Neurological disability in patients sustaining TSF. SAMPLE SIZE 1128 patients. RESULTS Of 1128 patients, 971 patients (86%) were male with a mean (SD) age 34.4 (16.6) years. The most common mechanism of injury was motor vehicle accidents (88.4%). Cervical spine was the most commonly affected region (48%, n=468) with a mortality rate of 7.6%. Neurological disability occurred in 74 (6.7%) patients, and 41 (8.7%) of those with cervical fractures died in the hospital. The Injury Severity Score was a significant predictor of neurological disability following TSF. CONCLUSION A high proportion of neurological disability following TSF was found. Further studies should attempt to improve the documentation rate of seatbelt status in all traumatic cases including mild injuries. This data will increase our understanding of adult TSF and possibly facilitate injury prevention strategies. LIMITATIONS Single hospital and may not be generalizable.
Background: Infection is the most common and devastating complication of open fractures, with a reported incidence of 3-40%. Tibia bone along its anteromedial surface has relatively thin soft tissue coverage; hence the open tibia fracture incidence rate ranges from 49.4% to 63.2%. Open fractures are usually classified based on the Gustilo & Anderson classification system, which is used by surgeons as an index for the severity of an injury and as a prognostic tool. Our current practice follows the 6-h rule of irrigation and debridement (I&D). Nevertheless, there is little support for this opinion in the literature. Our study concentrates on identifying the risk factors of infection in open tibia fractures and comparing the rate of infection if surgical irrigation and debridement was delayed. Methods: The medical records of 389 patients with open fractures were reviewed. Of these cases, 113 patients with open tibia fracture who presented to our Hospital from the period 1997 to 2008 fit the inclusion criteria and were included in a retrospective cohort study. Results: A total of 113 tibia fractures were reviewed, with an average patient age of 31.70 years; 87.1% of the fractures were high-energy fractures, and the most common mechanism of injury was a motor vehicle accident (62.4%). The data analysis revealed no difference in overall infectious outcome when comparing initial I&D performed within 6 h to when I&D was performed after 6 h (P = 0.201). The data analysis showed a significant relationship between infection and wound closure in first surgery in both univariate and multivariate analysis (P = 0.0003 and P = 0.014), respectively. Conclusion: This study showed no significant evidence to support the 6-h rule, but it did demonstrate a significant relationship between the Gustilo stage and infection, as well as an increased infection rate if external fixation was used or if the wound was left open during the initial irrigation and debridement. We believe that more studies are required to identify the relationship between infection and the delay in irrigation and debridement; a meta-analysis of the currently available data may provide an answer to this question.
The surgical treatment of delayed, unstable sub-axial cervical spine injuries is challenging. Multiple treatment regimens have been described in the literature, although there is no consensus regarding the best treatment approach. This report presents a 35-year-old obese woman who experienced a delayed sub-axial fracture-dislocation following a motor vehicle accident (MVA) and was successfully managed after three weeks via pre-operative traction followed by a novel single-surgery, single-approach technique with pedicle screws and tension-band wiring as a reduction method.A 35-year-old obese woman with a body mass index (BMI) of 30.1 sustained a frontal impact MVA and suffered from complete quadriplegia below C5 (American Spinal Cord Association Injury A) three weeks prior to presentation. She was intubated and presented with a Glasgow Coma Scale score of 11/15. Trauma computed tomography (CT) showed an isolated spine injury. Moreover, whole-spine CT showed an isolated cervical spine injury involving a basin tip fracture, a comminuted C1 arch fracture, a C2 fracture, and a C6-C7 fracture-dislocation. In addition, magnetic resonance imaging revealed cord contusion at the same level, with C1-C2 left atlantoaxial joint instability. Neck magnetic resonance angiograms and carotid CT angiograms showed left vertebral artery attenuation. She was admitted to the intensive care unit and taken for C6-C7 reduction and instrumentation using only a posterior approach after medical optimization and the application of sufficient traction.Delayed cervical spine fracture-dislocation imposes a challenge for surgical reduction. However, a proper reduction can be achieved through a sufficient duration of pre-operative traction and an isolated anterior or posterior approach.
