ABSTRACT

OBJECTIVES: The aim of this study was to investigate the accuracy of bedside ultrasound (US) performed by emergency physicians for diagnosing skull fractures in children 0 to 4 years old compared with the accuracy of head computed tomography (CT). We also sought to investigate characteristics and precautions associated with US. METHODS: This single-center prospective study involved children 0 to 4 years old who had a history of head trauma. Bedside US was performed by emergency medicine physicians, and the results were compared with CT scan interpretations provided by attending radiologists. The accuracy of US for the diagnosis of skull fractures was calculated, and the errors were reviewed. RESULTS: A total of 87 patients were enrolled. Skull fracture was present in 13 patients (14.9%), according to CT. Bedside US had a sensitivity and specificity of 76.9% (95% confidence interval [CI], 46.0%-93.8%) and 100% (95% CI, 93.9%-100%), respectively. Overall positive predictive value was 100% (95% CI, 65.5%-100%), and negative predictive value was 96.1% (95% CI, 88.3%-99.0%). Three false-negative cases were observed. CONCLUSIONS: Bedside US performed by emergency medicine physicians with short focused US training is a useful tool for diagnosing skull fractures in children 0 to 4 years of age. However, there were 3 false-negative cases. A meticulous examination is needed in the area adjacent to the orbital wall and skull base.

ABSTRACT

This study aimed to determine whether the combination of procalcitonin (PCT) and S100B improves prognostic performance compared to either alone in cardiac arrest (CA) patients treated with targeted temperature management (TTM).We performed a prospective cohort study of CA patients treated with TTM. PCT and S100B levels were obtained at 0, 24, 48, and 72 hours after return of spontaneous circulation. The prognostic performance was analyzed using each marker and the combination of the 2 markers for predicting poor neurological outcome at 3 months and mortality at 14 days and 3 months.A total of 97 patients were enrolled, of which 67 (69.1%) had poor neurological outcome. S100B showed a better prognostic performance (area under the curve [AUC], 0.934; sensitivity, 77.6%; and specificity, 100%) than PCT (AUC, 0.861; sensitivity, 70.2%; and specificity, 83.3%) with the highest prognostic value at 24 hours. The combination of 24-hour PCT and S100B values (S100B ≥0.2 µg/L or PCT ≥6.6 ng/mL) improved sensitivity (85.07%) compared with S100B alone. In multivariate analysis, PCT was associated with mortality at 14 days (odds ratio [OR]: 1.064, 95% confidence interval [CI]: 1.014-1.118), whereas S100B was associated with neurological outcomes at 3 months (OR: 9.849, 95% CI: 2.089-46.431).The combination of PCT and S100B improved prognostic performance compared to the use of either biomarker alone in CA patient treated with TTM. Further studies that will identify the optimal cutoff values for these biomarkers must be conducted.

ABSTRACT

BACKGROUND: The benefit of statin therapy in patients with higher grades of heart failure has yet to be determined. The present study investigated whether statin therapy affects major composite outcomes (MCOs) and all-cause mortality in patients with acute myocardial infarction (AMI) within 1 year after AMI, according to their plasma natriuretic peptide (NP) levels and left ventricular ejection fraction (LVEF). METHODS: A total of 11,492 patients with AMI from two nationwide registry databases in Korea were analyzed. AMI patients were divided into quartiles by plasma levels of B-type NP (BNP) or N-terminal pro-BNP (NT-proBNP) at admission. Patients with LVEF <40% on initial echocardiography were also evaluated. Total mortality and MCOs within 12 months of AMI, including death, nonfatal MI, and revascularization, were assessed. RESULTS: Among AMI patients, statin therapy was included in the discharge medications for 9075 (79.0%) patients, but not for the remaining 2417 patients (21.0%), and statin therapy was associated with a 27.8% lower risk of MCOs. After adjusting for risk factors, statin therapy was associated with lower hazard ratios for MCOs and all-cause mortality in only the third and fourth NP quartile subgroups, being effective only with moderate- to high-intensity statin therapy. However, statins did not modify the outcomes in patients with LVEF <40%. CONCLUSIONS: Our results show that moderate- to high-intensity statin therapy was associated with a lower risk of major clinical outcomes and all-cause mortality in AMI patients with higher plasma NP, but not in AMI patients with decreased LVEF.

ABSTRACT

Stroke in young adults has been known to show a lower incidence and a better prognosis. Only a few studies have examined the epidemiology and outcomes of ischemic stroke in young adults and compared them with the elderly in Korean population. All consecutive patients with ischemic stroke visiting 29 participating emergency departments were enrolled from November 2007 to October 2009. Patients with less than 15 yr of age and unknown information on age and confirmed diagnosis were excluded. We categorized the patients into young adults (15 to 45 yr) and elderly (46 yr and older) groups. Of 39,156 enrolled all stroke patients, 25,818 with ischemic stroke were included and analyzed (young adult; n=1,431, 5.5%). Young adult patients showed lower prevalence of most chronic diseases but significantly higher prevalence in exercise, current smoking, and alcohol consumption. Hospital mortality was significantly lower in young adults than elderly (1.1% vs. 3.1%, P<0.001). Higher number of patients in elderly group (68.1%) showed worsening change of modified Rankin Scale than young adults (65.2%). Young adults ischemic stroke showed favorable hospital outcomes than the elderly in Korean population.

ABSTRACT

AIM: The aim of this study is to investigate risk factors associated with the development of pneumonia during the first 7 days of admission in survivors of cardiac arrest receiving therapeutic hypothermia. METHODS: A total of 123 patients receiving therapeutic hypothermia after out-of-hospital cardiac arrest between January 2008 and December 2010 were enrolled. Study populations were categorized as "pneumonia present" [P (+)] and "pneumonia absent" [P (-)] contingent upon the development of pneumonia during the first 7 days of admission. Risk factors and outcomes related to development of pneumonia were determined. RESULTS: Fifty-nine patients (48.0 %) developed pneumonia, and P (+) patients had lower Acute Physiology and Chronic Health Evaluation II score (22 vs 26); longer durations of central venous catheter (8.9 vs 5.1 days), nasogastric tube (11.1 vs 3.8 days), mechanical ventilation (MV) (9.3 vs 3.7 days), and intensive care unit stay (10.0 vs 5.0 days); and higher rates of nasogastric feeding (66.1% vs 35.9 %), tracheostomy (52.5% vs 17.2 %), and postanoxic seizure (62.7% vs 39.1 %). In multivariate analyses, the occurrence of postanoxic seizure (odds ratio, 2.75; 95% confidence interval, 1.06-7.14; P = .04) and the length of MV (odds ratio, 1.33; 95% confidence interval, 1.15-1.52; P < .001) were independently associated with the development of pneumonia. The development of pneumonia had no significant association with survival (log-rank test, P = .15). CONCLUSION: Postanoxic seizure and prolonged duration of MV are independently associated with development of pneumonia. It may be helpful that we give more attention to the development of pneumonia in patients with postanoxic seizure and provide prompt diagnosis and treatment of postanoxic seizure.

ABSTRACT

PURPOSE: The aim of this study was to investigate the value of commonly examined laboratory measurements, including ammonia and lactate, in predicting neurologic outcome of out-of-hospital cardiac arrest (OHCA) patients treated with therapeutic hypothermia (TH). METHODS: This was a retrospective cohort study of patients with a return of spontaneous circulation after OHCA who were treated with TH between February 2007 and July 2010. We measured typical blood measurements on arrival at the emergency department. The subjects were classified into 2 groups: the good neurologic outcome group (Cerebral Performance Category [CPC] 1-2 at 1 month) and the poor neurologic outcome group (Cerebral Performance Category 3-5). We compared blood biomarker levels and basal characteristics between the 2 groups. Logistic regression analyses were performed to determine independent biomarkers that predict poor neurologic outcome. RESULTS: A total of 117 patients were included. Between the 2 groups, significantly different levels of blood measurements included hemoglobin level, pH, Pao(2), Paco(2), base excess, albumin, glucose, potassium, chloride, bilirubin, phosphorous, and ammonia. In multivariate analyses, blood ammonia level (>96 mg/dL; odds ratio [OR], 7.240; 95% confidence interval [CI], 1.718-30.512), noncardiac causes (OR, 46.215; 95% CI, 9.670-220.873), and time interval from collapse to return of spontaneous circulation (>33 min; OR, 5.943; 95% CI, 1.543-22.886) were significantly related to poor neurologic outcome. CONCLUSION: Among the blood measurements on emergency department arrival, blood ammonia (>96 mg/dL) was the only independent predictive biomarker of poor neurologic outcome. Thus, higher blood ammonia level was associated with poor neurologic outcome in OHCA patients treated with TH.
