    BACKGROUND: Ascariasis is one of the most common human parasitic infections worldwide. In some rare cases, ascariasis may cause serious consequences even sudden death. This study was undertaken to review the life-threatening complications of ascariasis in trauma patients reported in the literature.
    DATA SOURCES: Relevant articles about ascariasis and trauma were searched from Pubmed, Google scholar, Scirus, and Wanfang databases.
    RESULTS: Twenty-four patients with ascariasis were collected from 21 articles searched. Most of these patients were from tropical and subtropical countries. Of the 24 patients, 12 were children. Their major complications occurred in the airway passage and digestive tract. There were 3 fatal cases in these patients. Twelve of the 24 patients described in 10 articles were reported in the last 10 years.
    CONCLUSIONS: Early diagnosis and prompt intervention are essential to minimize the high morbidity and mortality of these serious complications in trauma patients. Physicians should be aware of the possibility of Ascaris infection in a trauma patient from endemic area of ascariasis. History of Ascaris infection and routine examination of feces for Ascaris eggs may be helpful to make a correct diagnosis.

    BACKGROUND: Coffee is commonly consumed among young people in China. However, consumers are rarely aware of physically adverse effects as a result of excessive consumption of caffeine.
    DATA SOURCES: A literature search using multiple databases was performed for articles published with concentration on meta-analyses, systematic reviews, and randomized controlled trials.
    RESULTS: Excess coffee consumption is also a risk of primary cardiac arrest especially in young people. Treatment modalities include activated charcoals, beta-blockers, vasopressin and hemodialysis when necessary.
    CONCLUSION: Coffee consumers should be advised not to routinely take more than moderate coffee.

    Hai-mu Yao, Tong-wen Sun, You-dong Wan, Xiao-juan Zhang, Xin Fu, De-liang Shen, Jin-ying Zhang, Ling Li
    2014, 5(3):  175-181.  doi:10.5847/wjem.j.issn.1920-8642.2014.03.003

    BACKGROUND: The application of coronary stents, especially drug-eluting stents (DESs), has made percutaneous coronary intervention (PCI) one of important therapeutic methods for CHD. DES has reduced the in-stent restenosis to 5%-9% and significantly improved the long-term prognosis of patients with CHD. The study aimed to investigate the long-term efficacy and safety of domestic drug-eluting stents (DESs) in patients with acute coronary syndrome (ACS).
    METHODS: All patients with ACS who had undergone successful percutaneous coronary intervention (PCI) in the First Affiliated Hospital of Zhengzhou University from July 2009 to December 2010 were included in this study. Patients were excluded from the study if they were implanted with bare metal stents or different stents (domestic and imported DESs) simultaneously. The included patients were divided into two groups according to different stents implanted: domestic DESs and imported DESs.
    RESULTS: In the 1 683 patients of this study, 1 558 (92.6%) patients were followed up successfully for an average of (29.1±5.9) months. 130 (8.3%) patients had major adverse cardiovascular events (MACEs), including cardiac death in 32 (2.1%) patients, recurrent myocardial infarction in 16 (1%), and revascularization in 94 (6%). The rates of cardiac death, recurrent myocardial infarction, revascularization, in-stent restenosis, stent thrombosis and other MACEs were not significantly different between the two groups (all P>0.05). Multivarite logistic regression revealed that diabetes mellitus (OR=1.75, 95%CI: 1.09-2.82, P=0.021), vascular numbers of PCI (OR=2.16, 95%CI: 1.22-3.83, P=0.09) and PCI with left main lesion (OR=9.47, 95%CI: 2.96-30.26, P=0.01) were independent prognostic factors of MACEs. The Kaplan-Meier method revealed that there was no significant difference in cumulative survival rates and survival rates free from clinical events between the two groups (all P>0.05).
    CONCLUSIONS: The incidences of clinical events and cumulative survival rates are not statistically different between domestic DESs and imported DESs. Domestic DES is effective and safe in the treatment of patients with ACS.

    BACKGROUND: Early reperfusion can effectively treat acute myocardial infarction (AMI) and reduce the mortality significantly. This study aimed to compare the role of plasma microRNA-1 (miR-1) and cardiac troponin T (cTnT) in early diagnosis of AMI patients.
    METHODS: From May 2011 to May 2012, plasma samples were collected from 56 AMI patients and 28 non-AMI controls. The expression of plasma miR-1 was measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR), and the level of plasma cTnT was measured using electrochemiluminescence-based methods on an Elecsys 2010 Immunoassay Analyzer. SPSS 16.0 was used for the statistical analysis of the results. Data were expressed as mean±standard deviation unless otherwise described. The differences about clinical characteristics between the AMI patients and controls were tested using Student's t test or Fisher's exact test. The Mann-Whitney U test was conducted to compare the expression of microRNAs between the AMI patients and controls. MicroRNAs expression between different intervals of the AMI patients was compared using Wilcoxon's signed-rank test. The receiver operating characteristic (ROC) curve was established to discriminate the AMI patients from the controls.
    RESULTS: In the present study, the expression of plasma miR-1 was significantly increased in the AMI patients compared with the healthy controls (P<0.01). The plasma miR-1 in the AMI patients decreased to the normal level at 14 days (P>0.05). The expression of plasma miR-1 was not related to the clinical characteristics of the study population (P>0.05). ROC curve analyses demonstrated that miR-1 was specific and sensitive for the early diagnosis of AMI, but not superior to cTnT.
    CONCLUSION: Plasma miR-1 could be used in the early diagnosis of AMI, but it is similar to cTnT.

    BACKGROUND: Epileptic seizures account for 1%-2% of all admissions of patients to the emergency department (ED). The present study aimed to determine whether venous blood pH, bicarbonate, base excess, and lactate levels taken within 1 hour of the last seizure episode help to determine seizure recurrence in emergency departments.
    METHODS: A cross-sectional study was conducted in the emergency department (ED) between January and July, 2012. Patients who were admitted to the emergency department consecutively were included in the study if they were 14 years or older and within 1 hour after last seizure. Demographics, seizure type, use of antiepileptic drugs, observation period at the emergency department, seizure recurrence, pH, bicarbonate, base excess, and lactate levels from venous blood gas analysis were determined.
    RESULTS: A total of 94 patients aged 14 years or older were included in the study. Of these patients, 10.6% (n=10) experienced recurrent seizures in the observation period at the emergency department. To predict recurrent seizures in ED, threshold venous blood gas values were determined as follows: pH<7.245 [sensitivity 80% (95%CI: 44-96), negative predictive value 96.9% (95%CI: 88.3-99.4)], bicarbonate<17.1 mmol/L [sensitivity 80% (95%CI: 44-96), negative predictive value 97% (95%CI: 89-99.5)], base excess<-11.1 mEq/L [sensitivity 80% (95%CI: 44-96), negative predictive value 97% (95%CI: 89-99)], and lactate>7.65 mmol/L [sensitivity 80% (95%CI: 44-96), negative predictive value 96.6% (95%CI: 87-99)].
    CONCLUSION: If venous blood gas analysis is made on pH, base excess, lactate and bicarbonate immediately one hour after the last epileptic seizure episode, it is possible to predict whether the patient will have seizure recurrence.

    BACKGROUND: Hemorrhage is the second leading cause of death in trauma patients preceded only by traumatic brain injury. But hemorrhagic shock is the most common cause of preventable death within 6 hours of admission. Traumatic coagulopathy is a hypocoagulable state that occurs in the most severely injured. International normalized ratio (INR) and its relationship with trauma mortality have not been studied specifically. This study aimed to establish a predictive value of INR for trauma-related mortality.
    METHODS: A total of 99 trauma patients aged 18-70 years were included in the study. Their INR was determined and patient progression was followed up till death/discharge. According to previous retrospective studies, the cutoff value for INR in our study was kept at 1.5.
    RESULTS: The total mortality rate of the patients was 16.16% (16/99). The mean INR was 1.45 with a SD of 1.35. INR was deranged in a total of 14 patients (14.14%). Of these patients, 11 died (78.57%) and 3 survived. INR was deranged in 11 (68.75%) of the 16 patients who died, but 5 deaths (31.25%) had normal INR values. The sensitivity of INR was 69% (95%CI 41%-88%) and the specificity 96% (95%CI 90%-99%). The diagnostic accuracy of INR was 92% (95%CI 85%-96%). Positive predictive value and negative predictive value were 79% (95%CI 49%-95%) and 94% (95%CI 87%-98%), respectively.
    CONCLUSION: Our results showed that INR is a good predictor of mortality in trauma patients.

    BACKGROUND: Competency in neonatal resuscitation is critical in the delivery rooms, neonatology units and pediatrics intensive care units to ensure the safety and health of neonates. Each year, millions of babies do not breathe immediately at birth, and among them the majority require basic neonatal resuscitation. Perinatal asphyxia is a major contributor to neonatal deaths worldwide in resource-limited settings. Neonatal resuscitation is effective only when health professionals have sufficient knowledge and skills. But malpractices by health professionals are frequent in the resuscitation of neonates. The present study was to assess the knowledge and skills of health professionals about neonatal resuscitation.
    METHODS: An institution based cross-sectional study was conducted in our hospital from February15 to April 30, 2014. All nurses, midwives and residents from obstetrics-gynecology (obs-gyn), midwifery and pediatric departments were included. The mean scores of knowledge and skills were compared for sex, age, type of profession, qualification, year of service and previous place of work of the participants by using Student's t test and ANOVA with Scheffe's test. A P value <0.05 was considered statistically significant.
    RESULTS: One hundred and thirty-five of 150 participants were included in this study with a response rate of 90.0%. The overall mean scores of knowledge and skills of midwives, nurses and residents were 19.9 (SD=3.1) and 6.8 (SD=3.9) respectively. The mean knowledge scores of midwives, nurses, pediatric residents and obs-gyn residents were 19.7 (SD=3.03), 20.2 (SD=2.94), 19.7 (SD=4.4) and 19.6 (SD=3.3) respectively. Whereas the mean scores of skills of midwives, nurses, pediatric residents and obs-gyn residents were 7.1 (SD=4.17), 6.7 (SD=3.75), 5.7 (SD=4.17) and 6.6 (SD=3.97) respectively.
    CONCLUSIONS: The knowledge and skills of midwives, nurses and residents about neonatal resuscitation were substandardized. Training of neonatal resuscitation for midwives, nurses and residents should be emphasized.

    BACKGROUND: The present study aimed to explore the relationship between surgical methods, hemorrhage position, hemorrhage volume, surgical timing and treatment outcome of hypertensive intracerebral hemorrhage (HICH).
    METHODS: A total of 1 310 patients, who had been admitted to six hospitals from January 2004 to January 2008, were divided into six groups according to different surgical METHODS: craniotomy through bone flap (group A), craniotomy through a small bone window (group B), stereotactic drilling drainage (group C1 and group C2), neuron-endoscopy operation (group D) and external ventricular drainage (group E) in consideration of hemorrhage position, hemorrhage volume and clinical practice. A retrospective analysis was made of surgical timing and curative effect of the surgical methods.
    RESULTS: The effectiveness rate of the methods was 74.12% for 1 310 patients after one-month follow-up. In this series, the disability rate was 44.82% 3-6 months after the operation. Among the 1 310 patients, 241 (18.40%) patients died after the operation. If hematoma volume was >80 mL and the operation was performed within 3 hours, the mortality rate of group A was significantly lower than that of groups B, C, D, and E (P<0.05). If hematoma volume was 50-80 mL and the operation was performed within 6-12 hours, the mortality rate of groups B and D was lower than that of groups A, C and E (P<0.05). If hematoma volume was 20-50 mL and the operation was performed within 6-24 hours, the mortality rate of group C was lower than that of groups A, B and D (P<0.05).
    CONCLUSIONS: Craniotomy through a bone flap is suitable for patients with a large hematoma and hernia of the brain. Stereotactic drilling drainage is suggested for patients with hematoma volume less than 80 mL. The curative effect of HICH individualized treatment would be improved via the suitable selection of operation time and surgical method according to the position and volume of hemorrhage.

    BACKGROUND: Cerebral stroke is a disease with a high disability rate and a high fatality rate.This study was undertaken to assess the risk of stroke associated pneumonia (SAP) in patients with ischemic stroke using A2DS2 score.
    METHODS: Altogether 1 279 patients with ischemic stroke who were treated in our department from 2009 to 2011 were retrospectively analyzed with A2DS2 score. A2DS2 score was calculated as follows: age ≥75 years=1, atrial fibrillation=1, dysphagia=2, male sex=1; stroke severity: NIHSS score 0-4=0, 5-15=3, ≥16=5. The patients were divided into three groups according to A2DS2 score: 620 in score 0 group, 383 in score 1-9 group, and 276 in score ≥10 group. The three groups were comparatively analyzed. The diagnostic criteria for SAP were as follows: newly emerging lesions or progressively infiltrating lesions on post-stroke chest images combined with more than two of the following clinical symptoms of infection: (1) fever ≥38 °C; (2) newly occurred cough, productive cough or exacerbation of preexisting respiratory tract symptoms with or without chest pain; (3) signs of pulmonary consolidation and/or wet rales; (4) peripheral white blood cell count ≥10×109/L or ≤4×109/L with or without nuclear shift to left, while excluding some diseases with clinical manifestations similar to pneumonia, such as tuberculosis, pulmonary tumors, non-infectious interstitial lung disease, pulmonary edema, pulmonary embolism and atelectasis. The incidence and mortality of SAP as well as the correlation with ischemic stroke site were analyzed in the three groups respectively. Mean± standard deviation was used to represent measurement data with normal distribution and Student's t test was used. The chi-square test was used to calculate the percentage for enumeration data.
    RESULTS: The incidence of SAP was significantly higher in the A2DS2 score≥10 group than that in the score 1-9 and score 0 groups (71.7% vs. 22.7%, 71.7% vs. 3.7%, respectively), whereas the mortality in the score≥10 group was significantly higher than that in the score 1-9 and score 0 groups (16.7% vs. 4.96%, 16.7% vs. 0.3%, respectively). The incidences of cerebral infarction in posterior circulation and cross-MCA, ACA distribution areas were significantly higher than those in the SAP group and in the non-SAP group (35.1% vs.10.1%, 11.4% vs. 7.5%, respectively). The incidence of non-fermentative bacteria infection was significantly increased in the score≥10 group.
    CONCLUSIONS: A2DS2 score provides a basis for risk stratification of SAP. The prevention of SAP needs to be strengthened in acute ischemic stroke patients with a A2DS2 score≥10.

    BACKGROUND: Acute liver failure (ALF) caused by viral and non-viral hepatitis is often accompanied with severe metabolic disorders, the accumulation of toxic substances and continuous release and accumulation of a large number of endogenous toxins and inflammatory mediators. The present study aimed to investigate the effects of various combined non-biological artificial liver treatments for patients with acute liver failure (ALF) complicated by multiple organ dysfunction syndrome (MODS).
    METHODS: Thirty-one patients with mid- or late-stage liver failure complicated by MODS (score 4) were randomly divided into three treatment groups: plasmapheresis (PE) combined with hemoperfusion (HP) and continuous venovenous hemodiafiltration (CVVHDF), PE+CVVHDF, and HP+CVVHDF, respectively. Heart rate (HR) before and after treatment, mean arterial pressure (MAP), respiratory index (PaO2/FiO2), hepatic function, platelet count, and blood coagulation were determined.
    RESULTS: Significant improvement was observed in HR, MAP, PaO2/FiO2, total bilirubin (TBIL) and alanine aminotransferase (ALT) levels after treatment (P<0.05). TBIL and ALT decreased more significantly after treatment in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.01). Prothrombin time (PT) and albumin were significantly improved only in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.05). TBIL decreased more significantly in the PE+HP+CVVHDF group than in the HP+CVVHDF and PE+CVVHDF groups (P<0.05). The survival rate of the patients was 58.1% (18/31), viral survival rate 36.4% (4/11), and non-viral survival rate 70% (14/20).
    CONCLUSION: Liver function was relatively improved after treatment, but PE+HP+CVVHDF was more efficient for the removal of toxic metabolites, especially bilirubin. The survival rate was significantly higher in the patients with non-viral liver failure than in those with viral liver failure.

    BACKGROUND: Continuous positive airway pressure (CPAP) with nasal devices (nCPAP) is widely used in the respiratory management of newborns. The present study aimed to compare the incidence of nasal trauma secondary to nasal continuous positive airway pressure (nCPAP) protected with or without hydrocolloid dressing in preterm infants.
    METHODS: This prospective controlled study was performed in the neonatal intensive care unit (NICU) of the Children's Hospital of Hunan Province from March 1, 2010 to June 31, 2010. A total of 65 infants, 46 males and 19 females, were recruited in this study. Their average gestational age was 32.6 weeks (range 28-37 weeks). The infants were randomly divided into clinical trial group (group A, n=33) and control group (group B, n=32). Paraffin oil was smeared around the nostrils before inserting prongs in group B; the infants in group A were covered on the infant's nostrils surface with hydrocolloid dressing (hydrocolloid dressing, 1.8 mm thick, 90029T, 3M Company, Minnesota, USA) with a size of 2-3 cm cutting two holes adapted to the nose and nostrils. The nostrils of those infants were inspected daily during nCPAP support until they were weaned off nCPAP.
    RESULTS: Nine infants (2 in group A and 7 in group B) developed nasal injury during nCPAP support. The Chi-square test revealed that there was a statistically significant difference (P=0.01) in the incidence of nasal injury between groups A and B.
    CONCLUSION: The study demonstrated that hydrocolloid dressing significantly decreased the incidence and the severity of nasal injury.

    BACKGROUND: Motor vehicles crashes (MVCs) are the leading cause of injury related morbidity and mortality in developed countries. Recent evidence proves that properly used child seat belts can dramatically reduce the risk of severe and life-threatening injury from MVCs. There are rarities of thought and inspiration regarding the use of child seat belts in our society and region, therefore we lack of data regarding factors and paucity of usage of child seat belts in motor vehicles. This study aimed to assess the knowledge and attitudes of child seat belt usage among the educated population in Karachi, Pakistan.
    METHODS: Altogether 304 employees were investigated. They were employees of Aga Khan University who were using their cars and having children younger than 10 years old. A cross sectional observational study was designed, and a 36-item questionnaire in English was used to collect data on participants' demographic details, designation, educational level, economic status, validity of driving license, number of children and cars, availability of adult seat belts and child seat belts along with their functionality, awareness, knowledge and attitude toward its use, and reason of not using these devices. SPSS version 20 for Windows was used to analyze the data and the Chi-square test was used.
    RESULTS: Totally 290 participants were recruited with a response rate of 72% (212). Of 212 participants, 126 (59%) were male. 154 (72.6%) participants had valid driver licenses, and 154 (72.6%) had adult seat belts in their vehicles. Only 32 (15%) reported regular use of adult seat belts. Although 168 (79.2%) participants had some knowledge about child restrains (CRs), only 65 (22%) had CRs in their cars. Eighty-two (38.7%) participants got the knowledge about CRs and seat belts from media. Mothers were more concerned about the use of CRs than fathers. Only 14 (6.6%) parents were found to use both adult and child seat belts all the time. Of the 157 parents who did not us use CRs, 42 considered unnecessary, 35 lacked relevant knowledge. But 15 parents used CR against their children's wills.
    CONCLUSIONS: The pattern of CR usage among the employees at Aga Khan University, Karachi is dictated by the unavailability of CR, followed by ignorance, inconvenience, and non-acceptance by their children. The important issue of CR has consistently been ignored over the years and it has never gained enough popularity in Pakistan.

    BACKGROUND: Acute pulmonary embolism (APE) is a disorder involving the pulmonary circulation resulting from a blockage of the pulmonary artery. The present study aimed to investigate the effects of aspirin on the nuclear factor-κB (NF-κB) activity in a rat model of APE.
    METHODS: A total of 108 healthy male Sprague-Dawley rats were randomly assigned into six groups (n=18 rats per group): control group, sham operation group, APE model group, and low-, medium- and high-dose aspirin groups. Six, 24, and 72 hours after the induction of APE, rats in the low-, medium- and high-dose aspirin groups were given aspirin at a respective daily dose of 150, 300, and 600 mg/kg by gavage for three consecutive days. Rats in the other groups were treated with equal volumes of normal saline. Six rats in each group were anesthetized with 10% chloral hydrate solution at each time point, and then the lung tissues were collected and analyzed using immunohistochemical staining.
    RESULTS: Positive immunohistochemical staining was present in the bronchial epithelial cells, alveolar cells, macrophages, and surrounding bronchial smooth muscle cells. When compared with the APE model group, the number of positive cells was significantly lower in the other groups at each time point (P<0.001). Statistically significant differences were also observed among the aspirin-treated groups at 6 hours (P<0.05, P<0.001). Compared with the APE model group, NF-κB protein expression was reduced in the other groups at each time point (P<0.05, P<0.001). Rats from the APE model group had thrombosis, damaged alveolar walls, and pulmonary hemorrhage, along with different degrees of inflammatory cellular infiltration at each time point. However, pathological changes such as pulmonary hemorrhage and infiltration of inflammatory cells were attenuated after the aspirin treatment.
    CONCLUSION: Aspirin can significantly inhibit NF-κB activity in the lung of rats with APE in a dose-dependent manner, and can alleviate lung injury after APE.

    BACKGROUND: Intestinal obstruction remains a common problem encountered in the surgical emergency, and usually occurs secondary to adhesions, obstructed herniae or tubercular strictures. However, at times, rare causes of obstruction can also be encountered.
    METHODS: A 24-year-old male patient presented with recurrent episodes of intestinal obstruction that was found to be secondary to an abdominal cocoon on laparotomy.
    RESULTS: The patient underwent adhesiolysis of the cocoon, and remains well on a follow-up. Histopathological report of the cocoon wall revealed fibrocollagenic tissues with a mixed inflammatory infiltrate, without any evidence of tuberculosis.
    CONCLUSIONS: Abdominal cocoon can be a rare cause of intestinal obstruction in male patients. Adhesiolysis of the cocoon membrane releases the obstruction and gives good results.
