BACKGROUND: We hypothesized that the direction of the J-tip of the guidewire during insertion into the internal jugular vein (IJV) might determine its ultimate location. METHODS: In this study, 300 patients between the ages of 18 and 99 years who required central venous catheterization via IJV in the emergency department enrolled for randomization. IVJ catheterization was successful in 285 of 300 patients. An independent operator randomly prefixed the direction of the J-tip of the guidewire to one of three directions. Based on the direction of the J-tip, patients were allocated into three groups: the J-tip medial-directed group (Group A), the lateral-directed group (Group B), or the downward-directed group (Group C). Postoperative chest radiography was performed on all patients in order to visualize the location of the catheter tip. A catheter is considered malpositioned if it is not located in the superior vena cava or right atrium. RESULTS: Of the total malpositioned catheter tips (8 of 285; 2.8%), the majority (5 of 8; 62.5%) entered the contralateral subclavian vein, 2 (25.0%) were complicated by looping, and 1 (12.5%) entered the ipsilateral subclavian vein. According to the direction of the J-tip of the guidewire, the incidence of malpositioning of the catheter tip was 4 of 92 in Group A (4.3%), 4 of 96 in Group B (4.2%), and there were no malpositions in Group C. There were no significant differences among the three groups (p = 0.114). CONCLUSIONS: The direction of the J-tip of the guidewire had no statistically significant effect on incidence of malpositioned tips.

It is well known that Rhododendron sclippenbashii contains the toxic material grayanotoxin. So, Koreans do not eat it, but they do eat azalea although it contains grayanotoxin. That is why there have been no reports about Rhododendron sclippenbashii intoxication after ingesting it intentionally, not accidentally. In this case, the patient was admitted to the emergency room with several toxic symptoms after intentionally consuming 50 blossoms of Rhododendron sclippenbashii to get rid of thirst. Treatment with saline infusion and atropine was successful and the outcome was favorable enough in this case to produce a complete cure without any sequelae at discharge. But toxic symptoms were seen for 24 hours, although the symptoms usually fade in 9 hours. Therefore, we should carefully treat and observe, for over 24 hours, the patient who intentionally ingests about 50 blossoms of Rhododendron sclippenbashii.

BACKGROUND: Early prediction of neurologic outcome is important to patients treated with therapeutic hypothermia after hypoxic brain injury. Hypoxic brain injury patients may have poor neurologic prognosis due to increased intracranial pressure. Increased intracranial pressure can be detected by optic nerve sheath diameter (ONSD) measurement in computed tomography (CT) or ultrasound. In this study, we evaluate the relation between neurologic prognosis and optic nerve sheath diameter measured in brain CT of hypoxic brain injury patients. METHODS: We analyzed the patient clinical data by retrospective chart review. We measured the ONSD in initial brain CT. We also measured and calculated the gray white matter ratio (GWR) in CT scan. We split the patients into two groups based on neurologic outcome, and clinical data, ONSD, and GWR were compared in the two groups. RESULTS: Twenty-four patients were included in this study (age: 52.6 +/- 18.3, 18 males). The mean ONSD of the poor neurologic outcome group was larger than that of the good neurologic outcome group (6.07 mm vs. 5.39 mm, p = 0.003). The GWR of the good neurologic outcome group was larger than that of the poor outcome group (1.09 vs. 1.28, p = 0.000). ONSD was a good predictor of neurologic outcome (area under curve: 0.848), and an ONSD cut off > or = 5.575 mm had a sensitivity of 86.7% and a specificity of 77.8%. CONCLUSIONS: ONSD measured on the initial brain CT scan can predict the neurologic prognosis in cardiac arrest and hanging patients treated with therapeutic hypothermia.

PURPOSE: We evaluated the utility of ultrasound-assisted lumbar puncture (UALP) in aged patients who visited our emergency center. METHODS:This was a prospective, randomized, controlled study. From July to December 2007 we enrolled patients who were at least 60 years of age . Patients were divided into a group that had lumbar puncture (LP) using landmark palpation (group A) and a UALP group (group B). We did between-group comparisons for the number of attempts, procedure time, the number of LP failures, and whether traumatic LP was done. For all hypotheses, a significance level of 0.05 was used. Variables are reported as percentages and mean +/-standard deviation. RESULTS: We enrolled sixty aged patients: 30 in group A and 30 in group B. There were 5 cases of LP failure in group A and none in group B (p<0.05). There were 6 cases of traumatic lumbar puncture in group A, and one case in group B (p=0.05). The number of attempts was 3.3+/-2.4 in group A and 1.5+/-0.8 in group B (p<0.05). It took 10.6+/-7.7 minutes to finish each LP in group A compared to 5.3+/-4.2 minutes in group B (p<0.05). CONCLUSION: The use of ultrasound-assisted lumbar puncture significantly reduces the number of failures, the number of attempts, and the procedure time in aged patients.

PURPOSE: To evaluate the utility of ultrasound-assisted lumbar puncture in the emergency department. METHODS: This was a prospective randomized controlled trial. We enrolled patients who were 18 years of age or older from May to August 2007. Patients were divided into a classic lumbar puncture group (group A) and an ultrasoundassisted lumbar puncture group (group B). We compared the frequency of attempting the procedure, the procedure time, the failure rate of lumbar puncture, and the traumatic lumbar puncture between groups. RESULTS: Sixty-one patients were enrolled in the study. Thirty-two patients were in group A and 29 patients were in group B. There were 6 cases of failed lumbar puncture in group A and one case in group B (p=0.07), and there were 3 cases of traumatic lumbar puncture in group A, and one case in group B (p=0.35). It took 8.6+/-8.4 minutes to accomplish lumbar puncture in group A compared to 8.2+/-6.4 minutes in group B (p=0.85). Overall, the frequency of attempting the procedure was 2.3+/-1.8 in group A and, 1.6 +/-1.1 in group B (p=0.66). In elderly patients (age> or =60 years) the frequency of attempting the procedure was 4.0+/-2.5 in group A and 1.6+/-0.5 in group B (p=0.03). There were 4 cases of failed lumbar puncture in group A but none in group B. CONCLUSION: Emergency physicians did not generally attempt ultrasound-assisted lumbar puncture in the emergency department. For elderly patients(> or =60 years), however, it was an available tool for emergency physicians and employed more frequently.

PURPOSE: To investigate the clinical characteristics and Alvarado scores of schizophrenia with patients acute appendicitis presenting at the emergency department. METHODS: We retrospectively reviewed medical records and identified schizophrenia patients who were diagnosed with acute appendicitis between January 2000 to December 2009 and who presented at the emergency department in 6 University hospitals. Comparisons were made with non-schizophrenic patients with acute appendicitis. Data collected included the patient's age, sex, clinical features, time interval between onset of symptoms and visiting the hospital, Alvarado score, disease complications, and diagnostic imaging modality. RESULTS: We identified 27 schizophrenia patients with acute appendicitis. Mean age was 34.5+/-8.3; 51.9% were women. The median time from onset of symptoms to visiting the emergency department was 3.8+/-1.4 days in the schizophrenic group and 2.3+/-2.1 in the normal control group. The mean Alvarado scores were 5.4+/-1.5 for the schizophrenic group and 6.5+/-2.1 for controls. Perforation of the appendix and formation of abscesses was higher in schizophrenic patients with appendicitis. CONCLUSION: These findings suggest that acute appendicitis is diagnosed late and with difficulty in schizophrenic patients and these patients may be the most vulnerable to failure to obtain timely surgical care. Early and careful access is recommended in suspected cases of appendicitis in schizophrenia patients.

PURPOSE: We evaluated a method to distinguish group A (abscess) from group B (cellulitis, pharyngitis, tonsillitis, epiglottis) through clinical variables in patients with a deep neck infection. METHODS: This was a retrospective chart review study consisting of the evaluation of CT scans or surgical diagnoses on adult patients (18 or more years of age). CT scans were reviewed by a radiologist. We evaluated several clinical variables in order to distinguish group A from group B. We also evaluated the ability of these clinical variables to distinguish group A from group B by a receiver operating characteristic curve. RESULTS: Sixty-three patients were enrolled in this study. Several clinical variables (swelling, odynophagia, tenderness, trismus, age>50years) differed between group A and group B. A AUC which was obtained by adding the number of variables (swelling, odynophagia, tenderness, trismus, age>50years) was 0.87 (p<0.01). The sensitivity and specificity of these clinical variables were 0.96 and 0.6 respectively, when the cut off value for adding the number of variables was set as 1.5. When the sum of these number of variables are more than two, the sensitivity is 0.958 (95% C.I:0.901~0.987) and the specificity is 0.600 (95% C.I:0.417~0.693). CONCLUSION: Five clinical variables (age>50, swelling, odynophagia, tenderness, trismus) were able to distinguish group A from group B.
