Item type:Item, An Initial Attack of Urinary Stone Disease Is Associated with an Increased Risk of Developing New-Onset Irritable Bowel Syndrome: Nationwide Population-Based Study(2016-06-23) ;Lei, Wei-Yuan ;Chang, Chih-Yu ;Wu, Jr-Hau ;Lin, Fei-HungChen, Cheng HsuBackground The neurotransmitter pathways in irritable bowel syndrome (IBS) and urinary stone attacks are both related to serotonin, and each disease may be influenced by viscero-visceral hyperalgesia. However, the relationship between urinary tract stone disease and IBS has never been addressed. We aimed to investigate the risk of suffering new-onset IBS after an initial urinary stone attack using a nationwide database. Methods A study group enrolled a total of 13,254 patients who were diagnosed with an initial urinary stone attack; a comparison group recruited 39,762 matched non-urinary stone participants during 2003 and 2007. We followed each patient for 3 years to determine new-onset IBS. We also used Cox proportional hazards models to analyze the risk of IBS between the study and comparison groups after modified by demographics, residence, patient characteristics and personal histories. Results The occurrence rates of IBS were 3.3% (n = 440) and 2.6% (n = 1,034) respectively in the study and comparison groups. A covariate-adjusted hazard ratio (HR) of IBS in the study group that was 1.28 times greater (HR = 1.29, 95% CI, 1.15-1.44) than that in the comparison group was showed in the stratified Cox proportional analysis. The adjusted HRs of IBS did not decrease after considering demographics and past histories. The majority of IBS (30.5%) occurred within the first 6 months after the stone attack. Conclusion Patients with an initial urinary stone attack are at increased risk of developing new-onset IBS. The HRs of IBS did not decrease even after adjusting for patient demographics and past histories. Most importantly, 30.5% of IBS occurred within the first 6 months after the urinary stone attack.Item type:Item, Characteristics and Risk Factors of Out-of-Hospital Cardiac Arrest Within 72 Hours After Discharge(2015-10-01) ;Syue, Yuan-Jhen ;Yen, Yung-Lin ;Cheng, Shih-Yu ;Hung, Chih-WeiLin, Yan-RenObjective:To determine the characteristics and risk factors for patients who developed out-of-hospital cardiac arrest (OHCA) within 72 hours after emergency department (ED) discharge.Methods:A nested case-control study (1:4 ratio) was conducted in 5 EDs from January 2002 to December 2011. The study group consisted of adults experiencing nontraumatic OHCA who revisited ED within 72 hours after discharge. Patients matched in sex, age group and chief complaints were selected for the control group. Demographic data, discharge diagnosis, discharge vital signs and laboratory result were collected. Etiologies of cardiac arrest and whether the events were expected or related to the 1st ED visit were reviewed.Results:In all, 1,657,870 patients were discharged during the study period; 109 developed OHCA within 72 hours of ED discharge (6.6/100,000 per year). The mean age was 64.7 years and 67.9% were men. After comparison with the control group, a higher heart rate (88.5 18.23 versus 81.7 +/- 15.93 beat per minutes, P = 0.003) and higher serum creatinine level (2.2 +/- 2.30 versus 1.4 +/- 1.38 mg/dL, P = 0.002) remain the statistical significant characteristics of study group by conditional logistic regression. Approximately 60% events were expected or unrelated to the 1st ED visit. Among patients whose OHCA were unexpected and related to the 1st ED visit, 71.4% had a cardiac cause. Of these, 20% had chest pain, but 40% had angina-equivalent symptoms during 1st presentation.Conclusions:A higher discharge heart rate and higher creatinine level are risk factors in these patients.Item type:Item, Clinical spectrum of rhabdomyolysis presented to pediatric emergency department(2013-09-03) ;Chen, Chun-Yu ;Lin, Yan-Ren ;Zhao, Lu-Lu ;Yang, Wen-ChiehChang, Yu-JunBackground: Rhabdomyolysis is a potentially life-threatening syndrome that can develop from a variety of causes. The aim of the work is to analyze the clinical spectrum and to evaluate the prevalence of various etiologies in children, who present to the emergency department (ED) with rhabdomyolysis. Methods: During a 6-year study period, we retrospectively analyzed the medical charts of patients, aged 18 years or younger, with a definite diagnosis of rhabdomyolysis and serum creatinine phosphokinase (CK) levels greater than 1000IU/L. We analyzed the clinical spectrum and evaluated the potential risk factors of acute renal failure (ARF). Results: Thirty-seven patients (mean age = 10.2 +/- 5.5 years), including 26 males and 11 females, were enrolled in the study. Two of the most common presented symptoms in these 37 patients were muscle pain and muscle weakness (83.8% and 73%, respectively). Dark urine was reported in only 5.4% of the patients. The leading cause of rhabdomyolysis in the 0- to 9-year age group was presumed infection, and the leading cause in the 10- to 18-year age group was trauma and exercise. The incidence of ARF associated with rhabdomyolysis was 8.1 % and no child needed for renal replacement therapy (RRT). We did not identify any reliable predictors of ARF or need for RRT. Conclusions: The classic triad of symptoms of rhabdomyolysis includes myalgia, weakness and dark urine are not always presented in children. The cause of rhabdomyolysis in younger age is different from that of teenager group. However, the prognosis of rhabdomyolysis was good with appropriate management.Item type:Item, Demographics of Pediatric OHCA Survivors With Postdischarge Diseases: A National Population-Based Follow-Up Study(2020-01-24) ;Lee, Tsung-Han ;Juan, I-Cheng ;Hsu, Hsiu-Ying ;Chen, Wen-LiangHuang, Cheng-ChiehBackground: Postdischarge diseases (PDDs) have been reported for adult survivors of out-of-hospital cardiac arrest (OHCA). However, the detailed demographics of pediatric OHCA survivors with PDDs are not well-documented, and information regarding functional survivors is particularly limited. We aimed to report detailed information on the PDDs of survivors of traumatic and non-traumatic pediatric OHCA using a national healthcare database. Methods: We retrospectively obtained data from the Taiwan government healthcare database (2011-2015). Information on the demographics of traumatic and non-traumatic pediatric OHCA survivors (<20 years) was obtained and reported. The patients who survived to discharge (survivors) and those classified as functional survivors were followed up for 1 year for the analysis of newly diagnosed PDDs. The time from discharge to PDD diagnosis was also reported. Results: A total of 2,178 non-traumatic and 288 traumatic OHCA pediatric cases were included. Among the non-traumatic OHCA survivors (n = 374, survival rate = 17.2%), respiratory tract (n = 270, 72.2%), gastrointestinal (n = 187, 50.0%), and neurological diseases (n = 167, 49.1%) were the three most common PDD categories, and in these three categories, the majority of PDDs were atypical/influenza pneumonia, non-infective acute gastroenteritis, and generalized/status epilepsy, respectively. Among the traumatic OHCA survivors (n = 21, survival rate = 7.3%), respiratory tract diseases (n = 17, 81.0%) were the most common, followed by skin or soft tissue (n = 14, 66.7%) diseases. Most functional survivors still suffered from neurological and respiratory tract diseases. Most PDDs, except for skin or soft tissue diseases, were newly diagnosed within the first 3 months after discharge. Conclusions: Respiratory tract (pneumonia), neurological (epilepsy), and skin or soft tissue (dermatitis) diseases were very common among both non-traumatic and traumatic OHCA survivors. More importantly, most PDDs, except for skin or soft tissue diseases, were newly diagnosed within the first 3 months after discharge.Item type:Item, Different urinalysis appearances in children with simple and perforated appendicitis(2013-11-01) ;Chen, Chun-Yu ;Zhao, Lu-Lu ;Lin, Yan-Ren ;Wu, Kang-HsiWu, Han-PingPurpose: This study aimed to determine whether routine urinalysis may serve as a tool in discriminating between acute appendicitis and perforated appendicitis in children. Basic procedures: We prospectively collected 357 patients with clinically suspected acute appendicitis. Urinalysis was performed in patients with clinically suspected acute appendicitis before surgical intervention. Routine urinalysis is composed of 2 examinations: chemical tests for abnormal chemical constituents and microscopic tests for abnormal insoluble constituents. Receiver operating characteristic curves for urine white blood cell (WBC) counts and urine red blood cell (RBC) counts in distinguishing between patients with simple appendicitis and patients with perforated appendicitis were also analyzed. Main findings: Urine ketone bodies, leukocyte esterase, specific gravity, pH, WBC, and RBC counts were all significant parameters among patients with normal appendices, simple appendicitis, and perforated appendicitis (all P < .05). Based on multivariate logistic regression analysis, positive urine ketone bodies and nitrate were significant parameters in predicting perforated appendicitis (P = .002 and P = .008, respectively). According to the results of receiver operating characteristic curves, the appropriate cutoff values were 2.0/high-power field for urine RBC counts and 4.0/high-power field for urine WBC counts in predicting perforated appendicitis in children. Principal conclusions: Routine urinalysis may serve to aid in discriminating between simple and perforated appendicitis. Clinically, we believe that these urine parameters may aid primary emergency physicians with decision making in patients with clinically suspected appendicitis. (C) 2013 Elsevier Inc.

Effective medications without adverse side effects are still not well characterized. We aimed to analyze whether early administration of glutamine could improve survival and protect cardiomyocytes from postcardiac arrest acidosis using animal and cell models. Forty Wistar rats with postcardiac arrest acidosis (blood pH < 7.2) were included. They were divided into study (500 mg/kg L-alanyl-L-glutamine, n = 20) and control (normal saline,n = 20) groups. Each of the rats received resuscitation. The outcomes were compared between the two groups. In addition, cardiomyocytes derived from human induced pluripotent stem cells were exposed to HBSS with different pH levels (7.3 or 6.5) or to culture medium (control). Apoptosis-related markers and beating function were analyzed. We found that the duration of survival was significantly longer in the study group (n < 0.05). In addition, in pH 6.5 or pH 7.3 HBSS buffer, the expression levels of cell stress (p53) and apoptosis (caspase-3, Bcl-xL) markers were significantly lower in cardiomyocytes treated with 50 mM L-glutamine than those without L-glutamine (RT-PCR). L-glutamine also increased the beating function of cardiomyocytes, especially at the lower pH level (6.5). More importantly, glutamine decreased cardiomyocyte apoptosis and increased these cells' beating function at a low pH level.Item type:Item, Early Epinephrine Improves the Stabilization of Initial Post-resuscitation Hemodynamics in Children With Non-shockable Out-of-Hospital Cardiac Arrest(2019-06-06) ;Lin, Yan-Ren ;Li, Chao-Jui ;Huang, Cheng-Chieh ;Lee, Tsung-HanChen, Tren-YiBackground: In children with non-shockable out-of-hospital cardiac arrest, early epinephrine (EE) might help to establish the return of spontaneous circulation (ROSC) and be associated with survival. In the present study, we aimed to analyze the effects of EE on outcomes and post-resuscitation hemodynamics in children with non-shockable OHCA. Methods: This was a retrospective analysis of data from 216 children (<19 years) who had suffered non-traumatic and non-shockable OHCA and received epinephrine for resuscitation (Jan 1, 2006-Dec 31, 2014). Demographics, pre-/in-hospital information, and the time to the first dose of epinephrine were recorded. Early post-resuscitation hemodynamics (the first hour after sustained ROSC), survival and good neurological outcomes (Pediatric Cerebral Performance Category Scales 1 or 2) were analyzed by the time to epinephrine-classified as early (EE): <15 min, intermediate (IE): 15-30 min, or late (LE): >30 min. Results: Twenty-eight (13.0%) children survived to discharge, but only 17 (7.9%) had good neurological outcomes. In all, 41 (18.9%) children received EE; in comparison to IE and LE, this was significantly associated with tachycardia (73.9%) in the post-resuscitation period (p < 0.05). Tachycardia (OR: 7.41, 95% CI: 1.96-29.31) and hypertension (OR: 6.03, 95% CI: 1.85-13.77) were significantly associated with EE after adjusting for confounding factors. EE was also significantly associated with better overall outcomes than ME and LE (any ROSC, sustained ROSC, survival to the intensive care unit, admission, survival to discharge and good neurological outcomes, all p < 0.05). Conclusions: EE helped to establish ROSC but was also associated with more tachycardia and hypertension in the early post-resuscitation period. In children with non-traumatic and non-shockable OHCA, EE was associated with a higher survival rate and better neurological outcomes than were ME and LE.Item type:Item, Epidemiology and outcome analysis of children with traumatic out-of-hospital cardiac arrest compared to nontraumatic cardiac arrest(2013-05-01) ;Chen, Chun-Yu ;Lin, Yan-Ren ;Zhao, Lu-Lu ;Wu, Yung-KangChang, Yu-JunThis study aimed to determine predictive factors for sustained return of spontaneous circulation (ROSC) in pediatric patients with traumatic out-of-hospital cardiac arrest (OHCA) and compared to those with nontraumatic OHCA. This was a retrospective prognostic study of children with OHCA presenting to the emergency department (ED) was conducted from 2005 to 2010. Related clinical factors that influenced sustained ROSC in traumatic OHCA patients were identified and compared to nontraumatic cases. Significant parameters in predicting sustained ROSC in traumatic OHCA children were also determined using multivariate logistic regression analysis, and etiologies of the ICU admissions were analyzed in patients with sustained ROSC. Among 2,978 critically ill children admitted to the ED, 150 were pediatric OHCA patients, including 76 traumatic cases and 74 nontraumatic cases. Of children with OHCA, initial sustained ROSC was achieved in 51 cases (34.0 %), including 31 traumatic cases and 20 of nontraumatic cases. Head and neck injuries were the majority of traumatic cases in the traumatic OHCA children, followed by abdominal injuries and chest injuries. However, abdominal injuries accounted for the highest rate to gain sustained ROSC, while chest injuries had the lowest rate for successful sustained ROSC. Significant factors associated with sustained ROSC in traumatic OHCA included initial cardiac rhythm (P < 0.05), the period from scene to hospital (P < 0.05), and the duration of in-hospital cardiopulmonary resuscitation (CPR) (P < 0.05). Significant factors related to sustained ROSC have been identified as initial cardiac rhythm, duration of in-hospital CPR, and the period from scene to hospital. Head and neck injuries were the majority of traumatic cases and the prevention in head and neck trauma may play an important part in public health aspects.Item type:Item, Factors associated with sustained return of spontaneous circulation in children after out-of-hospital cardiac arrest of noncardiac origin(2010-03-01) ;Li, Chao-Jui ;Kung, Chia-Te ;Liu, Ber-Ming ;Chou, Chu-ChungChang, Chin-FuPurpose: The study aimed to determine the factors predictive of sustained return of spontaneous circulation (ROSC) in children with out-of-hospital cardiac arrest (OHCA) of noncardiac origin. Methods: Eighty children were included in this retrospective study. The variables that lead to sustained ROSC and those that do not lead to sustained ROSC were analyzed. Survival analyses, including chance of achieving sustained ROSC and sum duration of ROSC, were conducted according to the duration of in-hospital cardiopulmonary resuscitation (CPR). Results: Etiologies of noncardiac OHCA differed significantly across different age groups (P < .001). Only 8.8% of children had initial arrest rhythms that were shockable. Predictors of sustained ROSC included the initial cardiac rhythm (P = .002), a shorter period between collapse and the first chest compression (P = .002), a shorter in-hospital CPR duration (P = .004), and prehospital CPR (P = .007). In children where ROSC was initially sustained, those with in-hospital CPR of more than 20 minutes, ROSC was sustained for less time (P < .001). Conclusions: Few children with noncardiac OHCA present with shockable cardiac rhythms. Furthermore, long-term ROSC is difficult to maintain in children who receive in-hospital CPR for more than 20 minutes. (C) 2010 Elsevier Inc.

HCC is one of the major causes of cancer deaths in worldwide, which remains poor prognosis and is clinically urgent for discovering early diagnostic markers. However, except for serum Hp, the correlation of tumor Hp expression with hepatocellular carcinoma (HCC) progression is still unclear. In this study, we evaluated and identified the tissue Hp expression as a prognostic marker to predict the survival rate of HCC patients. To evaluate the prognostic value of Hp expression for HCC, two cohorts were enrolled in our study, including total 130 matched pair tissue sections (both adjacent non-tumorous and tumor tissue derived from same patient) of HCC patients from Changhua Christian Hospital (CCH) and total 316 RNA-seq data with clinical information of HCC patients from The Cancer Genome Atlas (TCGA) database. In contrast to other types of cancers, HCC tumor tissues have lower Hp protein expression in CCH cohort and have lower Hp mRNA expression in TCGA cohort as compared with adjacent non-tumorous tissues (p < 0.001). Moreover, lower Hp expression is significantly correlated with different stages of HCC cancer differentiation in CCH cohort (one-way ANOVA, p < 0.001). Most importantly, lower Hp expression is highly correlated with poor five-year overall survival rate in TCGA cohort (p < 0.01). Based on our data, we conclude that tissue Hp expression positively correlates with better HCC tumor differentiation and increased five-year overall survival rate of HCC patients. The results indicated that tissue Hp is potentially a prognostic marker for HCC patients. Our findings may further provide a new insight of effective treatments along with biopsy diagnosis of HCC patients.Item type:Item, Hematuria as the only symptom at initial presentation of hypovolemic shock caused by ruptured renal arteriovenous malformations(2018-09-01) ;Chang, Yi-Jui ;Chou, Chu-Chung ;Chang, Chin-Fu ;Lin, Yan-Ren生物科技學系Gross hematuria is a very common complaint in emergency departments and outpatient clinics. Globally, the incidence of hematwia is 4 per 1000 patients per year. Infection, urolithiasis, and neoplasm are the most common etiologies. However, hematuria rarely causes hypovolemic shock or an emergent, life-threatening condition at the initial presentation. In this report, we describe the case of a 64-year-old man who suffered a life-threatening gross hematuria in a very short time due to ruptured renal arteriovenous malformations (AVMs).

The aim of this study was to analyze the early postresuscitative hemodynamics, survival, and neurologic outcome according to different time points of first epinephrine treatment among children with traumatic OHCA.Information on 388 children who presented to the emergency departments of 3 medical centers and who were treated with epinephrine for traumatic OHCA during the study period (2003-2012) was retrospectively collected. The early postresuscitative hemodynamic features (cardiac functions, end-organ perfusion, and consciousness), survival, and neurologic outcome according to different time points of first epinephrine treatment (early: <15, intermediate: 15-30, and late: >30minutes after collapse) were analyzed.Among 165 children who achieved sustained return of spontaneous circulation, 38 children (9.8%) survived to discharge and 12 children (3.1%) had good neurologic outcomes. Early epinephrine increased the postresuscitative heart rate and blood pressure in the first 30minutes, but ultimately impaired end-organ perfusion (decreased urine output and initial creatinine clearance) (all P<0.05). Early epinephrine treatment increased the chance of achieving sustained return of spontaneous circulation, but did not increase the rates of survival and good neurologic outcome.Early epinephrine temporarily increased heart rate and blood pressure in the first 30minutes of the postresuscitative period, but impaired end-organ perfusion. Most importantly, the rates of survival and good neurologic outcome were not significantly increased by early epinephrine administration.Item type:Item, Improving the reproducibility, accuracy, and stability of an electrochemical biosensor platform for point-of-care use(2020-05-01) ;Chen, Lung-Chieh ;Wang, Erick ;Tai, Chun-San ;Chiu, Yuan-ChenLi, Chang-WeiElectrochemical biosensors possess numerous desirable qualities for target detection, such as portability and ease of use, and are often considered for point-of-care (POC) development. Label-free affinity electrochemical biosensors constructed with semiconductor manufacturing technology (SMT)-produced electrodes and a streptavidin biomediator currently display the highest reproducibility, accuracy, and stability in modern biosensors. However, such biosensors still do not meet POC guidelines regarding these three characteristics. The purpose of this research was to resolve the limitations in reproducibility and accuracy caused by problems with production of the biosensors, with the aim of developing a platform capable of producing devices that exceed POC standards. SMT production settings were optimized and bioreceptor immobilization was improved through the use of a unique linker, producing a biosensor with exceptional reproducibility, impressive accuracy, and high stability. Importantly, the three characteristics of the sensors produced using the proposed platform all meet POC standards set by the Clinical and Laboratory Standards Institute (CLSI). This suggests possible approval of the biosensors for POC development. Furthermore, the detection range of the platform was demonstrated by constructing biosensors capable of detecting common POC targets, including circulating tumor cells (CTCs), DNA/RNA, and curcumin, and the devices were optimized for POC use. Overall, the platform developed in this study shows high potential for production of POC biosensors.Item type:Item, Increased Risk of Major Depression in the Three Years following a Femoral Neck Fracture-A National Population-Based Follow-Up Study(2014-03-13) ;Chang, Chih-Yu ;Chen, Wen-Liang ;Liou, Yi-Fan ;Ke, Chih-ChiLee, Hua-ChinFemoral neck fracture is common in the elderly, and its impact has increased in aging societies. Comorbidities, poor levels of activity and pain may contribute to the development of depression, but these factors have not been well addressed. This study aims to investigate the frequency and risk of major depression after a femoral neck fracture using a nationwide population-based study. The Taiwan Longitudinal Health Insurance Database was used in this study. A total of 4,547 patients who were hospitalized for femoral neck fracture within 2003 to 2007 were recruited as a study group; 13,641 matched non-fracture participants were enrolled as a comparison group. Each patient was prospectively followed for 3 years to monitor the occurrence of major depression. Cox proportional-hazards models were used to compute the risk of major depression between members of the study and comparison group after adjusting for residence and sociodemographic characteristics. The most common physical comorbidities that were present after the fracture were also analyzed. The incidences of major depression were 1.2% (n = 55) and 0.7% (n = 95) in the study and comparison groups, respectively. The stratified Cox proportional analysis showed a covariate-adjusted hazard ratio of major depression among patients with femoral neck fracture that was 1.82 times greater (95% CI, 1.30-2.53) than that of the comparison group. Most major depressive episodes (34.5%) presented within the first 200 days following the fracture. In conclusion, patients with a femoral neck fracture are at an increased risk of subsequent major depression. Most importantly, major depressive episodes mainly occurred within the first 200 days following the fracture.Item type:Item, Increased risk of major depression subsequent to a first-attack and non-infection caused urticaria in adolescence: a nationwide population-based study(2014-07-11) ;Kuo, Chia-Lun ;Chen, Chi-Yen ;Huang, Hui-Ling ;Chen, Wen-LiangLee, Hua-ChinBackground: Non-infection caused urticaria is a common ailment in adolescents. Its symptoms (e.g., unusual rash appearance, limitation of daily activities, and recurrent itching) may contribute to the development of depressive stress in adolescents; the potential link has not been well studied. This study aimed to investigate the risk of major depression after a first-attack and non-infection caused urticaria. Methods: This study used the Taiwan Longitudinal Health Insurance Database. A total of 5,755 adolescents hospitalized for a first-attack and non-infection caused urticaria from 2005 to 2009 were recruited as the study group, together with 17,265 matched non-urticarial enrollees who comprised the control group. Patients who had any history of urticaria or depression prior to the evaluation period were excluded. Each patient was followed for one year to identify the occurrence of depression. Cox proportional hazards models were generated to compute the risk of major depression, adjusting for the subjects\' sociodemographic characteristics. Depression-free survival curves were also analyzed. Results: Thirty-four (0.6%) adolescents with non-infection caused urticaria and 59 (0.3%) non-urticarial control subjects suffered a new-onset episode of major depression during the study period. The stratified Cox proportional analysis showed that the crude hazard ratio (HR) of depression among adolescents with urticaria was 1.73 times (95% CI, 1.13-2.64) than that of the control subjects without urticaria. Moreover, the HR were higher in physical (HR: 3.39, 95% CI 2.77-11.52) and allergy chronic urticaria (HR: 2.43, 95% CI 3.18-9.78). Conclusion: Individuals who have a non-infection caused urticaria during adolescence are at a higher risk of developing major depression.Item type:Item, Pharmaceutical Poisoning Exposure and Outcome Analysis in Children Admitted to the Pediatric Emergency Department(2011-02-01) ;Lin, Yan-Ren ;Liu, Tzu-Hsuan ;Liu, Tzu-An ;Chang, Yu-JunChou, Chu-ChungBackground: Pharmaceuticals involved in childhood poisoning vary, and treatment of poison exposure can be a challenge for primary physicians when children are unconscious or histories are lacking. Knowledge of the clinical manifestations and prognosis of poisoning will help primary physicians perform appropriate clinical assessments. In this study, we aim to report on patient characteristics, outcomes, and clinical features of pediatric poisoning in the emergency department. Methods: We retrospectively evaluated the medical records of 87 children younger than 18 years of age and presented to the emergency department with pharmaceutical poisoning (2001-2008). The detailed categories of pharmaceutical were reported, and their associations with patient outcomes were analyzed. Furthermore, children were divided into two groups, based on the reasons for poison exposure (accidental or intentional poisoning). Clinical features and outcomes between accidental or intentional poisoning were analyzed, and the cut-off age for high risk of intentional poisoning was also calculated. Results: Age groups of adolescents (48.3%) and preschool age (32.2%) children were the major representation. Neurologic system agents (48.3%) and analgesics (18.4%) were the most common causes of poisoning. Among the two major agents above, anxiolytic/hypnotic drugs (lorazepam) and acetaminophen were the most frequent causes. Of all children, 70.1% had duration of major symptoms for <= 1 day, and intentional poisoning caused significantly longer duration of hospital stay than accidental poisoning did (p = 0.008). Moreover, female gender (p < 0.001), older age (p < 0.001), and analgesics (p = 0.008) were more predominantly associated with intentional poisoning in children, and the cut-off age for high risk of intentional poisoning was over 10.5 years. Conclusion: Neurologic system agents and analgesics were responsible for the majority of cases. Intentional poisoning caused longer hospital length of stay than accidental poisoning, and the factors associated with intentional poisoning were older age, female, and neurologic system agents.

Methods: This retrospective study at an emergency department consisted of 140 children with poison exposure who were aged under 18 years. Their characteristics were analyzed in order to understand the differences between accidental and non-accidental poisoning. The poisonous materials were divided into two major categories (pharmaceuticals and non-pharmaceuticals) and their associations with patient outcomes were analyzed. Furthermore, the association was analyzed between the incidence of poison exposure and the season in which the poison exposure occurred. Results: The incidence of poison exposure was highest among adolescents and pre-school age children. Non-accidental poisoning was more common in older girls and accidental poisoning was more common in younger boys (P < 0.001). Neurological system agents were the most common cause of poisoning in the pharmaceutical group and cleansing products were the most common cause of poisoning in the non-pharmaceutical group. Neurological and gastrointestinal symptoms were the most common clinical presentations for the pharmaceutical and non-pharmaceutical groups, respectively. Furthermore, poisoning due to cleansing products and analgesics were associated with the longest duration of hospitalization. March was the highest risk month for pediatric poisoning (P=0.018). Conclusions: Cleansing products and analgesics were associated with the longest duration of hospitalization and intentional poison was more common in girls. World J Pediatr 2011;7(2):143-149Item type:Item, Post-resuscitative clinical features in the first hour after achieving sustained ROSC predict the duration of survival in children with non-traumatic out-of-hospital cardiac arrest(2010-04-01) ;Lin, Yan-Ren ;Li, Chao-Jui ;Wu, Tung-Kung ;Chang, Yu-JunLai, Shih-ChangAim of the study: Although sustained return of spontaneous circulation (ROSC) can be initially established after resuscitation from non-traumatic out-of-hospital cardiac arrest (OHCA) in some children, many of the children lose spontaneous circulation during hospital stay and do not survive to discharge. The aim of this study was to determine the clinical features during the first hour after ROSC that may predict survival to hospital discharge. Methods: We retrospectively evaluated the medical records of 228 children who presented to the emergency department without spontaneous circulation following non-traumatic OHCA during the period January 1996 to December 2008. Among these children, 80 achieved sustained ROSC for at least 20 min. The post-resuscitative clinical features during the first hour after achieving sustained ROSC that correlated with survival, median duration of survival, and death were analyzed. Results: Among the 80 children who achieved sustained ROSC for at least 20 min, 28 survived to hospital discharge and 6 had good neurologic outcomes (PCPC scale = 1 or 2). Post-resuscitative clinical features associated with survival included sinus cardiac rhythm (p = 0.012), normal heart rate (p = 0.008), normal blood pressure (p < 0.001), urine output > 1 ml/kg/h (p = 0.002), normal skin color (p = 0.016), lack of cardiopulmonary resuscitation (CPR)-induced rib fracture (p = 0.044), initial Glasgow Coma Scale score > 7 (p < 0.001), and duration of in-hospital CPR <= 10 min (p < 0.001). Furthermore, these variables were also significantly associated with the duration of survival (all p < 0.05). Conclusions: The most important predictors of survival to hospital discharge in children with OHCA who achieve sustained ROSC are a normal heart rate, normal blood pressure, and an initial urine output > 1 ml/kg/h.

Basic Procedures: The sample included 1075 children admitted to the emergency department with first-attack acute urticaria. Variables comprising the clinical features and past histories of children with duration of disease of 3 days or less, 4 to 7 days, 8 to 14 days, and 15 days or more were compared to determine the predictors of duration of acute urticaria. Main Findings: Age, various etiologies, clinical presentations, coexistent pyrexia or angioedema, and personal histories of allergic diseases were significant factors (all P < .05). Among allergic diseases, atopic dermatitis was the most significant predictor of duration of acute urticaria, and those with multiple allergic diseases had longer durations of urticaria (both P < .05). Oral plus injection forms of antihistamine or steroid were related to shorter duration of disease (P < .05). Principal Conclusions: Etiologies and personal allergy history may be the most important predictors of the duration of a first attack of acute urticaria. (C) 2011 Elsevier Inc.

The aim of this study was to determine the clinical features during the early postresuscitative period that may predict survival or neurologic outcomes in children with traumatic OHCA. METHODS: Information on 362 children (<19 years) who presented to the emergency departments of three medical centers and experienced traumatic OHCA during the study period (January 2003 to December 2010) were retrospectively included. The postresuscitative clinical features during the early postresuscitative period, defined as the first hour after achieving sustained return of spontaneous circulation, which correlated with survival and neurologic outcomes were analyzed. RESULTS: Among 152 children (42%) who achieved sustained return of spontaneous circulation, 34 (9.4%) survived to discharge, and 11 (3%) had good neurologic outcomes (Pediatric Cerebral Performance Category Scale, 1 or 2). Early postresuscitative clinical features, which reflected initial cardiac output and end-organ perfusion, can predict the chance of survival. Such features included the following: high or normal blood pressure, normal heart rate, sinus rhythm, urine output of more than 1 mL/kg per hour, and noncyanotic skin color (all p < 0.05). Initial Glasgow Coma Scale (GCS) score of greater than 7 predicted a good neurologic outcome in survivors (p = 0.008). CONCLUSION: Predictors of survival were high or normal blood pressure, normal heart rate, sinus rhythm, urine output of more than 1 mL/kg per hour, and noncyanotic skin color. Most importantly, initial GCS score of greater than 7 predicted a good neurologic outcome in survivors. (Copyright (C) 2013 by Lippincott Williams & Wilkins)
