Types, Patterns and Outcomes of Personal Watercraft- Related Trauma

Background: Personal watercraft (PWC) - related injuries have increased significantly as well as its popularity.Aim: We aimed to describe types, patterns and outcomes of PWC injuries in Qatar.Subjects and Methods: A retrospective analysis was conducted to identify patients admitted and treated for PWC-related injuries between 2008 and 2014. Data included patients demographics, mechanism of injury, Glasgow coma scale, injury severity scoring, Abbreviated Injury Score, location of injuries, hospital length of stay, ventilator days and mortality. Data were analyzed by the type of PWC (Jet Ski and motorboat).Results: A total of 39 patients were identified with PWC-related injuries. The majority of cases (71.8%, 28/39) were young and aged 21 to 40 years. Twenty-six cases were injured in Jet Ski accidents and 13 sustained motorboat-related injuries. Patients injured in Jet Ski accidents were younger than those involved in motorboat accidents (mean age (SD); 25(7.6) vs 32.6(6), p=0.01). Chest injury was the most common type of injury; however, the severity of injury was highest in head trauma as compared with other body regions. The injured anatomical regions, severity of injury and outcomes were comparable in the Jet Ski and motorboat-related injuries. Two fatalities were reported; one in Jet Ski-related accident which occurred due to severe head injury and the other patient died due to drowning following motorboat accident. The small sample size in this cohort is one of the limitations, however, given the small number of Qatar population, rarity of reported PWC-related injuries and the importance of paying attention of healthcare authorities for this mechanism of injury may counteract this limitation.Conclusion: PWC-related injuries are increasing and possess potential risk of severe injuries and disabilities among young population. Strict regulation for training and operation of PWC together with public awareness is needed to improve the safety of recreational injuries.Keywords: Personal watercraft, Jet Ski, Motorboat, Sport, Injury pattern, Outcom

Myocardial Viability: What We Knew and What Is New

Some patients with chronic ischemic left ventricular dysfunction have shown significant improvements of contractility with favorable long-term prognosis after revascularization. Several imaging techniques are available for the assessment of viable myocardium, based on the detection of preserved perfusion, preserved glucose metabolism, intact cell membrane and mitochondria, and presence of contractile reserve. Nuclear cardiology techniques, dobutamine echocardiography and positron emission tomography are used to assess myocardial viability. In recent years, new advances have improved methods of detecting myocardial viability. This paper summarizes the pathophysiology, methods, and impact of detection of myocardial viability, concentrating on recent advances in such methods. We reviewed the literature using search engines MIDLINE, SCOUPS, and EMBASE from 1988 to February 2012. We used key words: myocardial viability, hibernation, stunning, and ischemic cardiomyopathy. Recent studies showed that the presence of viable myocardium was associated with a greater likelihood of survival in patients with coronary artery disease and LV dysfunction, but the assessment of myocardial viability did not identify patients with survival benefit from revascularization, as compared with medical therapy alone. This topic is still debatable and needs more evidence

The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) Scoring: the Diagnostic and Potential Prognostic Role

BACKGROUND: Necrotizing fasciitis (NF) is a devastating soft tissue infection associated with potentially poor outcomes. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score has been introduced as a diagnostic tool for NF. We aimed to evaluate the prognostic value of LRINEC scoring in NF patients. METHODS: A retrospective analysis was conducted for patients who were admitted with NF between 2000 and 2013. Based on LRINEC points, patients were classified into (Group 1: LRINEC /= 6). The 2 groups were analyzed and compared. Primary outcomes were hospital length of stay, septic shock and hospital death. RESULTS: A total of 294 NF cases were identified with a mean age 50.9 +/- 15 years. When compared to Group1, patients in Group 2 were 5 years older (p = 0.009), more likely to have diabetes mellitus (61 vs 41%, p \u3c 0.001), Pseudomonas aeruginosa infection (p = 0.004), greater Sequential Organ Failure Assessment (SOFA) score (11.5 +/- 3 vs 8 +/- 2, p = 0.001), and prolonged intensive care (median 7 vs 5 days) and hospital length of stay (22 vs 11 days, p = 0.001). Septic shock (37 vs. 15%, p = 0.001) and mortality (28.8 vs. 15.0%, p = 0.005) were also significantly higher in Group 2 patients. Using Receiver operating curve, cutoff LRINEC point for mortality was 8.5 with area under the curve of 0.64. Pearson correlation analysis showed a significant correlation between LRINEC and SOFA scorings (r = 0.51, p \u3c 0.002). DISCUSSION: Early diagnosis, simplified risk stratification and on-time management are vital to achieve better outcomes in patients with NF. CONCLUSIONS: Beside its diagnostic role, LRINEC scoring could predict worse hospital outcomes in patients with NF and simply identify the high-risk patients. However, further prospective studies are needed to support this finding

Delayed bile leak in a patient with grade IV blunt liver trauma: A case report and review of the literature

AbstractIntroductionDelayed bile leak following blunt liver trauma is not common.Presentation of caseWe presented a case report and literature review of delayed bile leak in a young male patient who presented with grade IV blunt liver injury following a motor vehicle collision; he was a restrained driver who hit a fixed object. Physical examination was unremarkable except for revelaed tachycardia, right upper quadrant abdominal tenderness, and open left knee fracture. A diagnosis of grade IV multiple liver lacerations with large hemo-peritoneum was made and urgent exploratory laparotomy was performed. The patient developed a biloma collection post- operatively. He underwent endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct stenting. His recovery was uneventful, and he was discharged home after 1 month.DiscussionThis is a rare case with no intra or extra hepatic biliary radicle injury seen on magnetic resonance cholangiopancreatography (MRCP) and no evidence of leak by ERCP. A review of the literature to highlight the incidence of delayed bile leak revealed only few reported cases.ConclusionOur findings demonstrate the need for prompt diagnosis and treatment of delayed bile leak in blunt liver injuries. When these principles are followed, a successful outcome is possible

Emergency medical services (Ems) transportation of trauma patients by geographic locations and in-hospital outcomes: Experience from qatar

Background: Prehospital care provided by emergency medical services (EMS) plays an important role in improving patient outcomes. Globally, prehospital care varies across countries and even within the same country by the geographic location and access to medical services. We aimed to explore the prehospital trauma care and in-hospital outcomes within the urban and rural areas in the state of Qatar. Methods: A retrospective analysis was conducted utilizing data from the Qatar National Trauma Registry for trauma patients who were transported by EMS to a level 1 trauma center between 2017 and 2018. Data were analyzed and compared between urban and rural areas and among the different municipalities in which the incidents occurred. Results: Across the study duration, 1761 patients were transported by EMS. Of that, 59% were transported from an urban area and 41% from rural areas. There were significant differences in the on-scene time and total prehospital time as a function of urban and rural areas and municipalities; however, the response time across the study groups was comparable. There were no significant differences in blood transfusion, intubation, hospital length of stay, and mortality. Conclusion: Within different areas in Qatar, the EMS response time and in-hospital outcomes were comparable. This indicates that the provision of prehospital care across the country is similar. The prehospital and acute in-hospital care are accessible for everyone in the country at no cost. Understanding the differences in EMS utilization and prehospital times contributes to the policy development in terms of equitable distribution of healthcare resources

Clinical Presentation and Time-Based Mortality in Patients With Chest Injuries Associated With Road Traffic Accidents

Background: Blunt chest trauma (BCT) poses significant morbidity and mortality worldwide. Objectives: We investigated the clinical presentation and outcome of BCT related to road traffic accidents (RTA). Patients and Methods: A retrospective observational analysis for patients who sustained BCT secondary to RTA in terms of motor vehicle crash (MVC) and pedestrian-motor vehicle accidents (PMVA) who were admitted to the trauma center at Hamad general hospital, Doha, Qatar, between 2008 and 2011. Results: Of 5118 traumatic injury cases, 1004 (20%) were found to have BCT secondary to RTA (77% MVC and 23% PMVA). The majority were males (92%), and expatriates (72%). Among MVCs, 84% reported they did not use protective devices. There was a correlation between chest abbreviated injury score (AIS) and injury severity scoring (ISS) (r = 0.35, r2 = 0.12, P < 0.001). Regardless of mechanism of injury (MOI), multivariate analysis showed that the head injury associated with chest AIS and ISS was a predictor of mortality in BCT. Overall mortality was 15%, and the highest rate was observed within the first 24 hours post-trauma. Conclusions: Blunt chest trauma from RTA represents one-fifth of the total trauma admissions in Qatar, with a high overall mortality. Pedestrians are likely to have more severe injuries and higher fatality rates than MVC victims. Specific injury prevention programs focusing on road safety should be implemented to minimize the incidence of such preventable injuries

Early Versus Late Intramedullary Nailing for Traumatic Femur Fracture Management: Meta-Analysis

INTRODUCTION: There is no consensus yet on the impact of timing of femur fracture (FF) internal fixation on the patient outcomes. This meta-analysis was conducted to evaluate the contemporary data in patients with traumatic FF undergoing intramedullary nail fixation (IMN). METHODS: English language literature was searched with publication limits set from 1994 to 2016 using PubMed, Scopus, MEDLINE (OVID), EMBASE (OVID), Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL). Studies included randomized controlled trials (RCTs), prospective observational or retrospective cohort studies, and case-control studies comparing early versus late femoral shaft fractures IMN fixation. Variable times were used across studies to distinguish between early and late IMN, but 24 h was the most frequently used cutoff. The quality assessment of the reviewed studies was performed with two instruments. Observational studies were assessed with the Newcastle-Ottawa Quality Assessment Scale. RCTs were assessed with the Cochrane Risk of Bias Tool. RESULTS: We have searched 1151 references. Screening of titles and abstracts eliminated 1098 references. We retrieved 53 articles for full-text screening, 15 of which met study eligibility criteria. CONCLUSIONS: This meta-analysis addresses the utility of IMN in patients with FF based on the current evidence; however, the modality and timing to intervene remain controversial. While we find large pooled effects in favor of early IMN, for reasons discussed, we have little confidence in the effect estimate. Moreover, the available data do not fill all the gaps in this regard; therefore, a tailored algorithm for management of FF would be of value especially in polytrauma patients

Utility of indocyanine green fluorescent dye in emergency general surgery: a review of the contemporary literature

For decades, indocyanine green (ICG) has been available for medical and surgical use. The indications for ICG use in surgery have expanded where guided surgery directed by fluorescence and near-infrared fluorescent imaging offers numerous advantages. Recently, surgeons have reported using ICG operative navigation in the emergency setting, with fluorescent cholangiography being the most common procedure. The utility of ICG also involves real-time perfusion assessment, such as ischemic organs and limbs. The rising use of ICG in surgery can be explained by the ICG's rapid technological evolution, accuracy, ease of use, and great potential to guide precision surgical diagnosis and management. The review aims to summarize the current literature on the uses of ICG in emergency general surgery. It provides a comprehensive and practical summary of the use of ICG, including indication, route of administration, and dosages. To simplify the application of ICG, we subdivided its use into anatomical mapping and perfusion assessment. Anatomical mapping includes the biliary tree, ureters, and bowel. Perfusion assessment includes bowel, pancreas, skin and soft tissue, and gonads. This review provides a reference to emergency general surgeons to aid in implementing ICG in the emergency setting for more enhanced and safer patient care

Empirical pyridostigmine in a patient with difficult weaning from mechanical ventilation after traumatic brain injury

We present a 30-year-old male who sustained a mild traumatic brain injury and then was intubated due to deterioration of consciousness. A head CT scan revealed mild brain oedema, a fractured nasal bone and mild left thoracic wall haematoma. Despite complete clinical and radiological normalisation within 36 hours, he failed to wean off the ventilator. The patient was found to have subtle bulbar manifestations including dysphonia, dysarthria, and dysphagia, with recurrent left lung collapse. He responded to an empirical pyridostigmine trial despite negative biochemical tests for myasthenia gravis (MG). The patient was weaned successfully from the ventilator, transferred to a long-term care facility, and then discharged home. Classic symptoms and signs of a disease may be absent, but the presence of dysarthria, dysphagia, transient vocal cord palsy, nasal speech, absent gag reflex and respiratory failure in difficult-to-wean patients, with no definitive diagnosis, may warrant an empirical trial of therapy for suspected MG and for the benefit of any doubt

Validation of a Survey Questionnaire on Organ Donation: An Arabic World Scenario

Objective. To validate a questionnaire for measuring factors influencing organ donation and transplant. Methods. The constructed questionnaire was based on the theory of planned behavior by Ajzen Icek and had 45 questions including general inquiry and demographic information. Four experts on the topic, Arabic culture, and the Arabic and English languages established content validity through review. It was quantified by content validity index (CVI). Construct validity was established by principal component analysis (PCA), whereas internal consistency was checked by Cronbach’s Alpha and intraclass correlation coefficient (ICC). Statistical analysis was performed by SPSS 22.0 statistical package. Results. Content validity in the form of S-CVI/Average and S-CVI/UA was 0.95 and 0.82, respectively, suggesting adequate relevance content of the questionnaire. Factor analysis indicated that the construct validity for each domain (knowledge, attitudes, beliefs, and intention) was 65%, 71%, 77%, and 70%, respectively. Cronbach’s Alpha and ICC coefficients were 0.90, 0.67, 0.75, and 0.74 and 0.82, 0.58, 0.61, and 0.74, respectively, for the domains. Conclusion. The questionnaire consists of 39 items on knowledge, attitudes, beliefs, and intention domains which is valid and reliable tool to use for organ donation and transplant survey
