Objective
When managing patients with acute meningitis in an emergency department (ED), early diagnosis of the type of infection (bacterial or viral) considerably affects the clinical course and treatment because of the high mortality and morbidity associated with bacterial meningitis (BM). The serum delta neutrophil index (DNI), a new inflammatory marker, reflects the fraction of circulating immature granulocytes and is elevated in cases of bacterial infection. The objective of this study was to evaluate whether serum DNI can be used to differentiate between BM and viral meningitis (VM) in the ED.
Methods
This retrospective, observational study included 104 consecutive patients (aged >18 years) diagnosed with acute meningitis from January 2012 to November 2014 in a regional emergency center. White blood cell and neutrophil counts, C-reactive protein level, and DNI were evaluated regarding their usefulness for differentiating BM and VM.
Results
Serum DNI was not significantly higher in the BM group (n=12) than in the VM group (n=92) (0 [interquartile range, 0% to 2.73%] vs. 0 [interquartile range, 0 to 0%], P=0.057). However, the white blood cell count and C-reactive protein level were statistically higher in the BM group (P=0.034 and P=0.026, respectively). Serum DNI was not found to be a statistically useful differential diagnostic parameter (area under the curve, 0.628; 95% confidence interval, 0.438 to 0.818).
Conclusion
Currently, there is no evidence that the serum DNI aids in differentiating acute BM from acute VM in the ED.

Objective
Adverse cardiovascular events (ACVEs) account for a large proportion of the morbidities and mortalities associated with drug overdose emergencies. However, there are no published reports regarding outcomes of ACVEs associated with acute dapsone poisoning. Here, the authors retrospectively analyzed ACVEs reported within 48 hours of treatment in patients with acute dapsone poisoning and assessed the significance of ACVEs as early predictors of mortality.
Methods
Sixty-one consecutive cases of acute dapsone poisoning that were diagnosed and treated at a regional emergency center between 2006 and 2014 were included in the study. An ACVE was defined as myocardial injury, shock, ventricular dysrhythmia, cardiac arrest, or any combination of these occurring within the first 48 hours of treatment for acute dapsone poisoning.
Results
Nineteen patients (31.1%) had evidence of myocardial injury (elevation of serum troponin-I level or electrocardiography signs of ischemia) after dapsone overdose, and there were a total of 19 ACVEs (31.1%), including one case of shock (1.6%). Fourteen patients (23.0%) died from pneumonia or multiple organ failure, and the incidence of ACVEs was significantly higher among non-survivors than among survivors (64.3% vs. 21.3%, P=0.006). ACVE was a significant predictor of mortality (odds ratio, 5.690; 95% confidence interval, 1.428 to 22.675; P=0.014).
Conclusion
The incidence of ACVE was significantly higher among patients who died after acute dapsone poisoning. ACVE is a significant predictor of mortality after dapsone overdose, and evidence of ACVE should be carefully sought in these patients.

Objective

Therapeutic hypothermia (TH) has become the standard strategy for reducing brain damage in the postresuscitation period. The aim of this study was to investigate current TH performance and outcomes in out-of-hospital cardiac arrest (OHCA) survivors using data from the Korean Hypothermia Network (KORHN) registry.

Methods

We used the KORHN registry, a web-based multicenter registry that includes 24 participating hospitals throughout the Republic of Korea. Adult comatose OHCA survivors treated with TH between 2007 and 2012 were included. The primary outcomes were neurological outcome at hospital discharge and in-hospital mortality. The secondary outcomes were TH performance and adverse events during TH.

Results

A total of 930 patients were included, of whom 556 (59.8%) survived to discharge and 249 (26.8%) were discharged with good neurologic outcomes. The median time from return of spontaneous circulation (ROSC) to the start of TH was 101 minutes (interquartile range [IQR], 46 to 200 minutes). The induction, maintenance, and rewarming durations were 150 minutes (IQR, 80 to 267 minutes), 1,440 minutes (IQR, 1,290 to 1,440 minutes), and 708 minutes (IQR, 420 to 900 minutes), respectively. The time from the ROSC to coronary angiography was 1,045 hours (IQR, 121 to 12,051 hours). Hyperglycemia (46.3%) was the most frequent adverse event.

Conclusion

More than one-quarter of the OHCA survivors (26.8%) were discharged with good neurologic outcomes. TH performance was appropriately managed in terms of the factors related to its timing, including cooling start time and rewarming duration.
