BackgroundTo explore the relationship between enteroviruses and hospitalized children with hand, foot and mouth disease (HFMD) complicated with nervous system disease. 234 hospitalized HFMD patients treated in Shengjing Hospital, Liaoning Province were analyzed retrospectively. Based on the presence and severity of nervous system disease, the patients were grouped as follows: general patients, severely ill patients, critically ill patients and fatal patients. Based on the detected pathogen, the patients were grouped as follows: Enterovirus 71 (EV71) infection, coxsackie A16 (CA16) infection and other enterovirus (OE) infection.ResultsOf the 423 hospitalized patients, most were admitted in July 2010(129/423, 30.5%). Enteroviruses were detected in 177(41.8%). 272/423 patients were male (64.3%), and fatal patients had the greatest proportion of male patients (p < 0.05). EV71 infection was found in 89/423 patients (21%). CA16 infection was detected in 8/423 patients (16.1%). Compared to group CA16, patients in group EV71 were hospitalized earlier, and the duration of hospitalization was longer (p < 0.05). Of the 92 patients with nervous system damage, 65 were infected with EV71 and 19 were infected with CA16. Among these CA16 infected patients, 2 had brainstem encephalitis and 1 had AFP. There were more patients with nervous system dysfunction in group EV71 than in groups CA16 or OE (p < 0.05). The 5 fatalities all occurred in group EV71 patients (p < 0.05). Infection with EV71 was most likely to cause neurogenic pulmonary edema (p < 0.05). Patients in group EV71 had a higher rate of suffering from coma and limb movement disorder than patients in groups CA16 or OE (p < 0.05).ConclusionThe disease progresses faster in EV71-infected HFMD patients. These patients are more likely to suffer nervous system damage, neurogenic pulmonary edema, severe sequelae or death. CA16 and other enteroviruses can also cause HFMD with severe nervous system complications.

ObjectiveThe serotypes and patterns of antibiotic resistance of Streptococcus pneumoniae (S. pneumoniae) strains that cause invasive pneumococcal disease (IPD) in infants were analyzed to provide guidance for clinical disease prevention and treatment.MethodsThe clinical features of confirmed IPD were evaluated in 61 patients, less than 5 years of age, who were admitted to our hospital between January 2009 and December 2011. The serotypes and antibiotic resistance of strains of S.pneumoniae were determined using the capsular swelling method and the E-test.ResultsA total of 61 invasive strains were isolated. The serotype distribution of those isolates were 19A (41.0%), 14 (19.7%), 19F (11.5%), 23F (9.8%), 8 (4.9%), 9V (4.9%), 1 (3.3%), and 4, 6B, and 20 (each 1.6%). The percentage of S. pneumoniae strains resistant to erythromycin, clindamycin, and cotrimoxazole were 100%, 86.9%, and 100%, respectively. The percentage of S. pneumoniae strains resistant to penicillin, amoxicillin/clavulanic acid, cefuroxime, ceftriaxone, cefotaxime, cefepime, and meropenem were 42.6%, 18.0%, 82.0%, 18.0%, 13.1%, 13.1%, and 36.1%, respectively. The percentage of multidrug-resistant strains was 95.6%. Strains of all serotypes isolated in this study were highly resistant to erythromycin, cotrimoxazole, and clindamycin. Strains with serotype 19A had the highest rates of resistance.ConclusionsSerotype 19A strains were most frequently isolated from children with IPD treated in our hospital. The strains causing IPD are highly resistant to antibiotics.

The oil of Acer truncatum Bunge seed (ASO) is rich in ω-9 (53.93%) and ω-6 (30.7%) fatty acids (FAs), and characterized by 3-7% nervonic acid (NA, C24:1ω-9). Evidence suggests that...

Background: Although Epicutaneo cava catheters (ECCs) are being routinely used for intravenous access for long-term parenteral nutrition and prolonged medication administration in neonates, ECC use can be associated with rare but acute life-threatening events such as pleural effusion (PE). It is important to identify and maintain the ECC tip in a central location for preventing complications. Recently, intracavitary electrocardiogram (IC-ECG) has been developed for the real-time monitoring and verification of ECC tip position. Objective: To investigate the causes and preventive measures of ECC-related PE in neonates. Methods: This prospective cohort study was conducted between January 2013 and December 2017. We observed and analyzed the clinical characteristics and causes of ECC-related PE. From January to December 2017, all ECCs were guided by IC-ECG. The incidence of ECC-related PE and first-attempt success rates were analyzed before and after the introduction of IC-ECG. Additionally, the sensitivity and specificity of IC-ECG were evaluated. Results: ECC-related PE was identified in 14 infants. Catheters were malpositioned in three cases; in the other 11 cases, catheters were located centrally on insertion but had migrated to non-central locations at the time of PE. After the introduction of IC-ECG, the incidence of PE was zero ( P < 0.05). The incidence of ECC-related PE was lower when veins of the lower extremities were selected as the insertion site ( P < 0.05). The first-attempt success rate was significantly higher in the group with IC-ECG-guided ECC placement than in the group without ( P < 0.05). The sensitivity and specificity of IC-ECG were 97.9 and 84.6%, respectively. Conclusion: ECC-related PE can be associated with either primary malposition or migration of the catheter tip. IC-ECG can help detect malposition and migration of catheter tips and improve the first-attempt success rate. Choosing a lower extremity insertion site may help decrease the rate of ECC-related PE. In neonates, IC-ECG is a reliable positioning method for ECCs with superior sensitivity and specificity.

Introduction: Despite tremendous progress made toward elimination, measles continues to pose a great threat to the health of children in developing countries. The objective of this study was to summarize and analyze the clinical characteristics and treatment experience of serious complications of measles pneumonia in children. Methodology: The study group comprised 58 infants with severe measles pneumonia who were admitted to the Second Pediatric Intensive Care Unit, Shengjing Hospital of China Medical University, from December 2013 through May 2014. The clinical characteristics of complications such as hypoxemia, acute respiratory distress syndrome (ARDS), sepsis, pneumothorax, multiple organ dysfunction syndrome (MODS), and intracranial infection were retrospectively analyzed; in addition, the death cases were summarized and analyzed. Results: The 58 infants experienced the following: hypoxemia, 100%; ARDS, 21%; sepsis, 34%; pneumothorax, 14%; MODS, 16%; and intracranial infection, 9%. A total of 7 infants developed a secondary bacterial infection, and 12 infants received mechanical ventilation (5 with high-frequency mechanical ventilation and 3 with mechanical ventilation and NO inhalation); the average duration of mechanical ventilation was 10.08 days, and 3 infants expired. Conclusions: Children with measles pneumonia may experience multiple serious complications, among which ARDS and pneumothorax are particularly serious. If a patient's condition changes abruptly, it is crucial to promptly respond to the change and to administer mechanical ventilation and appropriate antibiotics. For patients with a severe pneumothorax, and especially those with severe mediastinal emphysema, timely, continuous, retrosternal, closed thoracic drainage can effectively relieve compression.
