Clinical Features of Patients Presenting to the Emergency Department With Cardiovascular Adverse Reactions After COVID-19 mRNA Vaccination

Background@#Since the implementation of the nationwide coronavirus disease 2019 (COVID-19) vaccination campaign, emergency departments (EDs) have had an increasing number of patients reporting postvaccination cardiovascular adverse effects. We investigated the clinical features of patients who visited the ED for cardiovascular adverse reactions after COVID-19 mRNA vaccination. @*Methods@#We conducted a retrospective observational study in two EDs. Patients with cardiovascular adverse reactions after COVID-19 mRNA vaccination who visited EDs between June 1, 2021, and October 15, 2021, were selected. The clinical data of these patients were collected by reviewing medical records. @*Results@#Among 683 patients, 426 (62.4%) were female. The number of patients in their 20s was the highest (38.9% of males, 28.2% of females) (P < 0.001). More patients visited the ED for adverse reactions following the first vaccine dose than following the second dose (67.6% vs. 32.2%). Chief complaints were chest pain/discomfort (74.4%), dyspnea (14.3%) and palpitation (11.3%). The final diagnosis was a nonspecific cause (63.1%), and 663 (97.1%) patients were discharged from the ED. The admission rate was higher in males than in females (3.9% vs. 1.9%). Myocarditis was diagnosed in four males, who showed mild clinical progression and were discharged within 5 hospital days. @*Conclusion@#Most patients who visited the ED with cardiovascular adverse reactions were discharged from the ED, but some were admitted for other medical diseases as well as adverse vaccine reactions. Therefore, further surveillance and a differential diagnosis of cardiovascular adverse events after COVID-19 mRNA vaccination should be considered by emergency physicians.

Clinical features and risk factors for missed stroke team activation in cases of acute ischemic stroke in the emergency department

OBJECTIVE: Acute ischemic stroke (AIS) requires time-dependent reperfusion therapy, and early recognition of AIS is important to patient outcomes. This study was conducted to identify the clinical features and risk factors of AIS patients that are missed during the early stages of diagnosis. METHODS: We retrospectively reviewed AIS patients admitted to a hospital through the emergency department. AIS patients were defined as ischemic stroke patients who visited the emergency department within 6 hours of symptom onset. Patients were classified into two groups: an activation group (A group), in which patients were identified as AIS and the stroke team was activated, and a non-activation group (NA group), for whom the stroke team was not activated. RESULTS: The stroke team was activated for 213 of a total of 262 AIS patients (81.3%), while it was not activated for the remaining 49 (18.7%). The NA group was found to be younger, have lower initial National Institutes of Health Stroke Scale scores, lower incidence of previous hypertension, and a greater incidence of cerebellum and cardio-embolic infarcts than the A group. The chief complaints in the A group were traditional stroke symptoms, side weakness (61.0%), and speech disturbance (17.8%), whereas the NA group had non-traditional symptoms, dizziness (32.7%), and decreased levels of consciousness (22.4%). Independent factors associated with missed stroke team activation were nystagmus, nausea/vomiting, dizziness, gait disturbance, and general weakness. CONCLUSION: A high index of AIS suspicion is required to identify such patients with these findings. Education on focused neurological examinations and the development of clinical decision tools that could differentiate non-stroke and stroke are needed.

Clinical Characteristics and Risk Factors in Severely Injured Elderly Trauma Presenting to Emergency Department

BACKGROUND: With increasing life expectancy, the number of injured elderly patients has been increasing. We evaluated the clinical characteristics of severely injured elderly patients who presented to the Emergency Department and identified risk factors associated with mortality. METHODS: Injured patients over 18 years of age who visited the Emergency Department with trauma team activation were investigated. We divided the patients into two groups according to age, an older adult group (> or =65 years) and a younger adult group ( or =3 of each body area, and mortality between the two groups. RESULTS: Among 177 severely injured patients, there were 138 younger adults (78%) and 39 older adults (22%). The average ISS of the older adults was higher than the younger adults (20.66 vs. 16.37). The incidences of severe injuries (ISS>15) in the younger adults and the older adults were 50.0% and 71.1%, respectively, and critical injuries (ISS>25) were 16.7% and 36.8%, respectively. Chest injuries and subdural hematoma occurred more often in the older adults. Mortality was higher in the older adults (28.2%) than in the younger adults (8.7%). CONCLUSION: The average ISS was higher in older adults than in younger adults, and older adults were significantly more likely to suffer severe trauma, especially chest injuries and subdural hematoma. The rate of mortality was greater for older adults (28.2%) than younger adults (8.7%).

Chief Complaints and Related Features of Elderly Patients Presenting to One Region Wide Emergency Medical Center With Medical Problems

BACKGROUND: This research is to determine the chief complaints and related features of elderly patients who are presented to emergency department with medical problems. METHODS: Medical records of patients, 65 years or above, who visited Uijeongbu Hospital Emergency Center between January 1, 2012 and June 30, 2012 were reviewed retrospectively. Age, gender, mode of transportation to the hospital, chief complaints, and diagnosis were among the subjects analyzed. RESULTS: Elderly patients with medical problems, 3,468 visited the emergency department, constituting 12.66% from 27,396 patients in total during the research period. Patients aged 70 to 74 were 28.45%, composing the most among the age groups. Ambulance was the mode of transportation used by 43.06% of the patients and 42.96% of them stayed overnight, while 11.13% stayed in the intensive care units. The most frequent chief complaints were abdominal pain (16.81%), dyspnea (13.96%), and fever (11.16%). The most common diagnosis for patients with abdominal pain was gastritis (20.75%), chronic heart failure (26.03%) for dyspnea, and pneumonia (28.96%) for fever. The main diagnoses of in-patients according to the order of frequency were cerebral vascular accident (16.38%), pneumonia (12.48%), and chronic heart failure (6.04%). CONCLUSION: The number of elderly patients who stayed overnight and stayed in the intensive care units have increased comparing to younger patients. The top 10 most frequent chief complaints accounted for 78.92% by medical elderly patients. The results of this research could be used for the development of geriatric emergency medicine training programs and critical pathway for interns and residents.

The Values of the Pediatric Logistic Organ Dysfunction (PELOD) Score and the Pediatric Index of Mortality (PIM) 2 Score in Emergency Department and Intensive Care Unit / 대한구급학회지

BACKGROUND: This study was conducted to compare two models of the pediatric logistic organ dysfunction (PELOD) score and the pediatric index of mortality (PIM) 2 score in the emergency department (ED) and intensive care unit (ICU). METHODS: 90 pediatric patients who were admitted to the ICU in ED from January 2003 to December 2008 were enrolled in this study. PELOD score and PIM 2 score calculations were performed in the ED and ICU. We classified these patients into either the survivor or non-survivor groups and analyzed the clinical variables between two groups. We used Hosmer-Lemeshow goodness-of-fit tests to evaluate calibration, receiver operating characteristic (ROC) curves and standardized mortality ratio (SMR). RESULTS: Among the 90 pediatric patients, 56 (62.2%) were male, and 9 (10.0%) patients died. Expected mortalities were PIM 2 = 10.35, PELOD = 8.33 in ED and PIM 2 = 8.84, PELOD = 8.26 in ICU. PIM 2 showed fit calibration (x(2) = 6.228, p = 0.622) in the ED. In the ICU, both PELOD and PIM 2 showed calibration (x(2) = 4.625, p = 0.185) and (x(2) = 7.616, p = 0.472), respectively. PIM 2 in ED showed the best discrimination, with area under the curve (AUC) = 0.949 (95% CI, 0.881-0.984). CONCLUSIONS: PIM 2 score in ED was fit. Also, PELOD and PIM 2 score in ICU was fit. But PELOD in ED was unfit.

The Expression of Cytochrome c, TNF-R1 and Fas Ligand in Patient's Serum after Successful Cardiopulmonary Resuscitation

PURPOSE: Numerous reports have suggested that apoptosis may play an important role in postresuscitation syndrome. The aim of this study is to assess the levels of molecules that are associated with apoptosis in the serum of patients who underwent successful resuscitation after cardiac arrest. METHODS: The serum levels of cytochrome c, tumor necrosis factor type 1 receptor (TNF-R1) and Fas ligand in 11 patients were measured at 0, 4, 12, 24, 48 and 72 hours after successful resuscitation. The primary endpoint consisted of survival to hospital discharge. Ten healthy volunteers were also evaluated as a control group. RESULTS: Patients with successful resuscitation had increased levels of cytochrome c and TNF-R1 at 0, 4, 12, 24 and 48 hours after return of spontaneous circulation (ROSC), as compared with those levels of the healthy volunteers (p<0.05). Higher levels of TNF-R1 at 12, 24 and 48 hours after ROSC were found in the non-survivors as compared to those levels of the survivors (p=0.01, 0.03, 0.02). The Fas ligand level at ROSC was also higher in the patients with successful resuscitation (p=0.00). However, the Fas ligand levels at 24, 48 and 72 hours after ROSC were lower in the patients with successful resuscitation than those levels in the healthy volunteers. CONCLUSION: These results suggest that apoptosis belonging to the TNF-R1 and cytochrome c pathways may be involved in the pathogenesis of postresuscitation syndrome. The serum levels of the death-receptor TNF-R1 could serve to quantitate the severity of injury and to prognosticate the survival outcomes.

Effect of Alcohol Ingestion on Clinical Features of Acute Drug Intoxicated Patients

PURPOSE: This study was conducted to see the effect of alcohol ingestion on clinical features of acute drug intoxicated patients. METHODS: We prospectively investigated drug intoxicated patients who visited the emergency department 6 hours after acute poisoning from January 2004 to December 2007. Patients were classified into two groups according to serum alcohol levels: an alcohol group (serum alcohol level>10 mg/dl) and a non-alcohol group. The type of toxic material, age, sex, duration of time to arrive to the emergency department (ED) after poisoning, mean arterial pressure, respiratory rate, base excess level, AST level, serum creatinine level, cause of poisoning, suicide attempt, past psychiatric history, discharge against medical advice rate, and admission rate were checked. The initial and final Poisoning Severity Score (PSS), the Glasgow coma scale, the length of stay in the intensive care unit (ICU), the usage of a mechanical ventilator, and death rate were also checked. RESULTS: The study enrolled 222 intoxicated patients of which 75 fell into the non-alcohol group and 147 into the alcohol group. Alcohol ingestion of acute poisoning in males was higher than in females. The AST level and discharge against medical advice rates in the alcohol group were higher than the non-alcohol group. The base excess level, length of stay in ICU, past psychiatric history rate, and admission rates in the non-alcohol group were higher than the alcohol group. The PSS were not correlated with alcohol consumption between the two groups. CONCLUSION: Alcohol ingestion is not associated with PSS. However, alcohol ingestion is commonly found in acute drug intoxicated patients. The discharge against medical advice rate in the alcohol group was higher than the non-alcohol group.

Predictive Value of C-reactive Protein and Kidney Computed Tomography in Patients with Acute Pyelonephritis

PURPOSE: This study was conducted to determine the predictive value of the C-reactive protein (CRP) and kidney computed tomography (CT) in the emergency department (ED) for predicting the severity of acute pyelonephritis. METHODS: One hundred thirty-nine patients who were diagnosed with acute pyelonephritis between January 2007 and June 2008 were enrolled in this study. The patient underwent a kidney CT in the ED and the CT findings were classified as normal, a focal wedge-shaped lesion, a multi-focal wedge-shaped lesion, a mass-effect lesion, and abscess formation. The symptoms, vital signs, past history, initial laboratory findings, serum CRP in the ED, and the length of the hospital stay based on the kidney CT grade in the ED were compared. RESULTS: Among the 139 patients, 138 were females and the mean age was 48.5+/-17.7 years. We classified the CT grades as follows: grade 1, normal (n=20); grade 2, focal wedge-shaped lesion (n=25); grade 3, multi-focal wedgeshaped lesion (n=45); grade 4, mass-effect lesion (n=42); and grade 5, abscess formation (n=7). Statistically significant differences in leukocyte count, neutrophil ratio, ESR, CRP, and length of hospital stay existed between the CT grades. Patients were classified into two groups based on the CT grade (the mild group [grades 1 and 2], and the severe group [grades 3~5]). The leukocyte count, neutrophil ratio, ESR, CRP, maximal body temperature, duration of fever, duration of pyuria >3 days, and length of hospital stay were greater in the severe group. Based on the results of multivariate logistic regression analysis, the CRP level was shown to be an independent predictor that affected the severe group. The area under the ROC curve for CRP was 0.775 (95% CI, 0.695~0.854). CONCLUSION: The CRP level in the ED was an independent predictor that affected the severe group. Thus, the initial CRP level with the kidney CT grade may be used as a prognostic indicator of acute pyelonephritis in the ED.

Clinical Analysis of Acute Poisoning in Elderly Patients

BACKGROUND: Incidents of suicide attempts and acute poisonings in the elderly population is rising. This study com- pared elderly and younger patients to investigate the influence of age on the clinical nature of acute poisoning. METHODS: We retrospectively investigated 147 patients with acute poisoning who visited the emergency department within 6 hours of exposure. Patients were divided into two groups, young adult(20-40 yrs) and elderly(> or =55 yrs). Information on type of toxic material, age, sex, duration of time to arrive to the emergency department(ED) after poisoning, cause of poisoning, usage of activated charcoal and gastric lavage, previous suicide attempts, and past psy- chiatric history were collected. And, the mean arterial pressure, respiratory rate, base excess, aspartate aminotransfe- rase(AST), serum creatinine, rate of discharge against medical advice, intensive care unit(ICU) admission rate, discharge rate, duration in ICU, usage of mechanical ventilator, and death rate were analyzed. Initial and final Poisoning Severity Scores(PSS) of each patient were calculated. RESULTS: The mean age of the young adult group and the elderly group were 30.6+/-6.1 yrs and 66.6+/-8.2 yrs, respectively. Cause of poisoning was accidental more often in the elderly group than in the young adult group. AST and creatinine levels were higher and base excess was lower in the elderly group. ICU admission rate, duration in ICU, usage of mechanical ventilator, death rate, and initial and final PSS were all higher in the elderly group as well. CONCLUSION: This study showed that the PSS and death rate from acute poisoning were higher in the elderly group than in the young adult group.

A Case Report and Systemic Analysis of Articles for Morgagni Diaphragmatic Hernia

It was difficult to determine the clinical situations of Morgagni diaphragmatic hernias of adults on account of its rarity. The aim of this study was to propose diagnostic and therapeutic guidelines for adult Morgagni diaphragmatic hernias. A computerized `Korean study information co.' and `medical research information center' literature search of domestic articles published since 1950 was carried out. These 10 cases in addition to ours were analyzed. The average age at treatment was 68.7 years of age ranging from 51 to 83 years with 90.9% of patients being female. 18.2% of patients had symptoms immediately after trauma. 27.3% of patients were incorrectly diagnosed preoperatively. 90.9% of all treated Morgagni hernias were located on the right side just behind the sternum with hernia sacs. The most common contents of the hernias were the greater omentum and transverse colon. The preferred method of surgery was the trans-abdominal approach. The mortality rate of the hernias was 9.1%. Morgagni diaphragmatic hernias once diagnosed should be referred for surgical repair due to the risk of bowel perforation. The transabdominal approach or laparoscopic surgery is preferred in accurately diagnosed Morgagni diaphragmatic hernias prior to surgery.

Incidence and Significance of Negative Hematuria in Patients with Urolithiasis Visiting the Emergency Room with Flank Pain

PURPOSE: This research was conducted to determine the incidence of negative hematuria in patients with urolithiasis in Korea and the significance during evaluation of a patient' s complaining of flank pain. METHODS: We evaluated 363 consecutive patients who were suspected of having urolithiasis and who underwent intravenous urography (IVU). All patients underwent urinalysis and a urine dipstick test (UDT). We evaluated the sensitivity, the specificity, the positive predictive value and the negative predictive value of UDT, urinalysis and a combination of these two tests, and we compared the rates of incidence of negative hematuria. In addition, we estimated the relation between the RBC count and the severity of the ureteral obstruction. RESULTS: The IVU was positive in 206 of the 363 patients. The incidence of negative hematuria for urinalysis, UDT, and the combination were 9.2%, 8.7% and 6.3%, respectively. Thirteen patients (3.6%) had another disease. There was no correlation between the degree of ureteral obstruction and the incidence of negative hematuria (p= 0.713). Also, no correlation was established between the degree of ureteral obstruction and RBC count (p=0.742). CONCLUSIONS: In patients with urolithiasis, the incidences of negative hematuria for urinalysis, UDT and a combination of the two tests were 9.2%, 8.7% and 6.3%, respectively. The presence or absence of hematuria in patients with acute renal colic should not determine whether a more definitive study is performed.

Clinical Study of Thyrotoxic Periodic Paralysis in the Emergency Department

PURPOSE: Thyrotoxic periodic paralysis (TPP) is not an uncommon disorder in patient with acute muscle weakness in the emergency department. However, many patients with TPP are misdiagnosed, leading to improper treatment. So, we analyze the clinical characteristics of TPP to make diagnosis and treatment properly. METHODS: The medical records of the patients confirmed as TPP by using thyroid function test from January 1998 to December 2002 were reviewed retrospectively. RESULTS: TPP occurs predominantly in males, especially young males, during dawn or morning. It's predisposing factors were heavy meals, physical exertion and alcohol drinking. Most patients were hypokalemic and in a normal acid-base state. Systolic hypertension and tachycardia were common in TPP because of the hyperadrenergic state. When hyperthyroidism was conversed to normal thyroid state, paralysis did not occur. CONCLUSION: There were several clinical clues to the diagnosis of TPP. Rapid and accurate diagnosis of TPP is important, so emergency physicians must know its clinical characteristics.

Death from Ingestion of beta-fluoroethyl Acetate Rodenticide

The highly toxic sodium monofluoroacetate (SMFA) was banned as a rodenticide in this country in the 1980s. The fluoroacetate metabolite, fluorocitric acid blocks cellular metabolism by inhibiting the Klebs cycle, producing widespread clinical effects including respiratory, neurologic, cardiologic, and fluid-electrolyte abnormalities. We report the case of intentional ingestion of a derivative product, beta-fluoroethyl acetate. A 79-yr-old female was brought to the emergency room without any problem. At 2hours post ingestion, she had a generalized tonic-clonic seizure and then, was unresponsive to painful stimuli. At 6hours post ingestion, she died from refractory ventricular fibrillation. We report this patient to increase awareness of beta-fluoroethylacetate toxicity.

Prediction of Poor Outcome in Comatose Survivors after Cardiopulmonary Resuscitation with Somatosensory Evoked Potentials and Proton Magnetic Resonance Spectroscopy

PURPOSE: The study was conducted to examine the usefulness of somatosensory evoked potentials (SEP) and proton magnetic resonance spectroscopy (1H-MRS) in predicting poor outcomes for comatose survivors after cardiopulmonary resuscitation. METHODS: We investigated 36 patients who were comatose after cardiac arrest. Among them, 35 had short latency SEP, and 27 had 1H-MRS. Both tests were performed in 26 patients. To estimate the cerebral outcome, we used the cerebral performance category (CPC) to classify the outcomes for our patients as good (CPC 1-2) or poor (CPC 3-5). RESULTS: Of the 36 patients, 11(31%) presented with good outcomes (CPC 1-2). A bilaterally absent N20 peak (n=35) predicted poor outcomes with a sensitivity of 54.2% and a specificity of 100%. A lactate-positive resonance (n=27) predicted poor outcomes with a sensitivity of 78.9% and a specificity of 100%. Using a combination of a bilaterally absent N20 peak and a lactate-positive resonance (n=26) predicted poor outcomes with a sensitivity of 94.4% and a specificity of 100%. CONCLUSION: The combination of a bilaterally absent N20 peak and a lactate-positive resonance is better than either alone in predicting poor outcomes in patients who are comatose after cardiac arrest.

Torsion of an Accessory Spleen Presenting as an Acute Abdomen: A Case Report

An accessory spleen is often incidentally discovered in up to 20% of autopsies. However, it is exceedingly rare for this condition to result in an acute abdomen. In addition, torsion of an accessory spleen is extremely rare. In spite of this, the entity should be considered in the emergency department in the differential diagnosis of an acute abdomen associated with an intraperitoneal inflammatory mass. This report describes a case of acute torsion of an accessory spleen. A 26-year-old, previously health female was admitted to our hospital with severe abdominal pain and a palpable mass. Ultrasonography showed a well-defined ovoid, hypoechogenic, avascular mass. Computed tomography demonstrated a round, homogeneous hypodense mass with a whorling appearance and an engorged vascular structure in the left side of the mass. The presumptive diagnosis of a large exoenteric mass (small bowel or mesenteric origin) associated with mesenteric volvulus was made preoperatively. However, at laparotomy, the patient was found to have torsion and an infarction of an accessory spleen that had twisted on its long vascular pedicle.

Intrapericardial Diaphragmatic Hernia Associated With Cardiac Tamponade

Herniation of intra-abdominal contents into the pericardial cavity is rare. We observed a delayed intrapericardial diaphragmatic hernia presenting as a tamponade secondary to a previous pericardioperitoneal window for drainage of a pericardial effusion. The diagnosis of an intrapericardial hernia should be considered in patients presenting with gastrointestinal and/or cardiorespiratory symptoms following surgical procedures involving the diaphragm.

Which is the Treatment of Choice for Acute Acetaminophen Overdose in a Situation Where a Serum Level Determination is Not Available Within 8 Hours: Oral or Intravenous N-Acetylcysteine Treatment?

PURPOSE: The purpose of this study was to develop therapeutic decision guidelines on N-acetylcysteine (NAC) treatment for acetaminophen (AAP) overdose in a situation where a serum level determination is not available within 8 hours. METHODS: We reviewed retrospectively the medical records of patients admitted for AAP overdose from January 2001 to February 2004. Forty-nine patients met inclusion criteria; patients with acute AAP overdose who were exposed to 7.5 g or 140 mg/kg or greater, determination of the serum level was not available within 8 hours, and NAC treatment was started empirically before identification of the serum level. The patients had been treated with a 72hour oral or a 20hour intravenous (IV) NAC treatment protocol. RESULTS: Patients were classified into an Oral NAC (n=24) group and an IV NAC (n=25) group based on the treatment protocol. There were no significant intergroup differences in patient characteristics, time variables, distribution of risk categories, and hepatotoxicity. All the patients in both toxic groups were fully recovered, and the difference in the number of adverse reactions during NAC treatment were not significant between the two groups (Oral NAC vs IV NAC, 4 (16%) vs. 2 (8%), respectively; p=0.417). The numbers of patients who discontinued the NAC treatment were 14 (58%) in the Oral NAC group and 8 (32%) in the IV NAC group (p=0.088). The six patients in the nontoxic category of IV NAC group were already completed before determination of the serum level. CONCLUSION: Therapeutic decisions for AAP overdose which are based entirely on ingestion history have some limitations. IV NAC is as effective as oral treatment for patients with acute AAP overdose. If the serum level is not available within 8 hours, the clinician should preventively administer the first dose of oral NAC to patients without severe vomiting. Subsequently, when the serum level is determined, the need for additional therapy should be determined to reduce unnecessary use of NAC. However, if the patients present with severe vomiting or contraindications to oral treatment, intravenous administration is required.

Retroperitoneal Ectopic Pregnancy: A Case Report

A retroperitoneal ectopic pregnancy is a very rare form of extrauterine pregnancy and is a potentially life threatening variation of ectopic gestation within the retroperitoneal cavity. In fact, the clinical history, physical examination, laboratory and vaginal ultrasonographic findings are non specific. It is a surgical emergency because of high maternal and fetal morbidity and mortality. Early diagnosis is essential. Surgical intervention is indicated as soon as the diagnosis is made. We report our experience with one retroperitoneal ectopic pregnancy with a brief review of the literature

Change in the Intrathecal Cytokine level in Hypoxic-ischemic Encephalopathy after Cardiac Arrest

PURPOSE: This study was performed to evaluate the changes in the IL-1beta and the IL-6 concentrations in cerebrospinal fluid (CSF) after initial successful cardiopulmonary resuscitation (CPR), to examine the difference in the IL-1beta and the IL-6 concentrations in CSF between the cerebral performance category (CPC) 1-2 group and CPC 3-5 group after successful CPR, and to identify early makers predicting the outcome after successful CPR. METHODS: We studied prospectively 10 patients with spontaneous circulation after CPR. Samples of CSF were taken at 20 min, 4 hr, 24 hr, and 48 hr after restoration of spontaneous circulation. The control group was consisted of the nonspecific 6 patients in brain computed tomography and CSF finding among the visited patients in emergency department with complaints of headache. The CSF IL-1beta and IL-6 were measured by using enzyme-linked immunosorbent assays. RESULTS: 1) The concentrations of CSF IL-6 for CPC 3-5 were higher in the successful CPR group than in the control group. 2) In the severely neurologically disabled group (CPC 3-5), the concentrations of CSF IL-6 were significantly higher at 20 min 4 hr, 24 hr and 48 hr after successful CPR than they were in the mildly neurologically disabled group(CPC 1-2). 3) The concentrations of CSF IL-6 in the severely neurologically disabled group (CPC 3-5) reached peak levels at 24 hours after successful CPR. 4) The concentrations of CSF IL-1beta did not differ between the two groups. CONCLUSION: Our study indicates that CSF IL-6 is increased more in the severely neurologically disabled group (CPC 3-5) than it is in the mildly neurologically disabled group (CPC 1-2) after successful CPR. We found a significant relationship between the concentration of CSF IL-6 and initial outcome for the CPR patient. Thus, we suggest that CSF IL-6 might play a role in brain ischemic-reperfusion injury and might be used as a prognostic marker after successful CPR.

Clinical Manifestations of Vivax Malaria Diagnosed Patients

PURPOSE: In this study, we analyzed clinical manifestations of and ways to manage malaria. METHODS: The medical records of the patients confirmed as malaria by using peripheral blood smear at Ui jungbu St. Mary's hospital from April 1997 to November 2001 were reviewed retrospectively. RESULTS: Of the 170 patients, there were 111 males and 59 females, and their mean ages were 32.3+/-14.5, 34.9+/-18.1 years, respectively. Malaria occurred throughout the year and peaked during the sixth to ninth months (84.1%). All cases were vivax malaria. All 170 patients had fever, but tertian fever was seen in only 81 (48%) patients. Laboratory abnormalities were hemoglobin below 12 g/dL in 70 (41.2%) patients, WBC below 4000/mm3 in 49 (28.9%), platelet count below 120,000/mm3 in 142(83.5%). Of the 92 patients who underwent ultrasonography of the abdomen, splenomegaly was seen in 81 (89%)patients. The time from onset of symptoms to admission ranged from 2 to 30 days with a mean 8.1+/-5.5 days. All patients responded promptly to drug therapy. One patient developed recurrent malaria 120 days after the first attack. Another patient experienced multifocal splenic infarction. CONCLUSION: All patients with malaria had fever and chills. The most common laboratory findings were thrombocytopenia and anemia. All patients responded promptly to drug therapy. As cases of malaria in Korea are increasing, early diagnosis and treatment, as well as prevention, are important.
