Objective To assess the distinguishing features of aseptic meningitis (AM) in patients with Kawasaki disease (KD) compared with bacterial meningitis (BM) patients. Methods Thirty-eight patients with KD and 126 patients with BM were retrospectively investigated. The following clinical manifestations and laboratory parameters were compared between the two groups: duration of fever before lumbar puncture, conjunctival injection, oral cavity changes, rash, cervical lymphadenopathy and extremity changes, vomiting, front fontanel bulging, neck stiffness, leukocyte number, hemoglobin level, platelet number, C-reactive protein level, cerebrospinal fluid (CSF) content, liver enzyme level, and urinalysis. Results Vomiting and neck stiffness were more prevalent in patients with BM. KD patients with AM showed elevated blood leukocyte numbers and C-reactive protein levels in the early febrile stage. CSF glucose was significantly lower in patients with BM compared with KD patients with AM. Receiver operating characteristic curve analysis showed that the optimal cutoff value of CSF glucose for discrimination of BM and AM/KD was 2.945 mmol/L, with a sensitivity of 84.2% and a specificity of 71.4%. Conclusions Detailed investigations of clinical manifestation and laboratory parameters are necessary to distinguish AM and BM in patients with KD. Decreased CSF glucose is a potential indicator of BM.
Patent ductus arteriosus (PDA) is a particularly common problem in preterm infants. Although surgical ligation is rarely performed in many contemporary neonatal intensive care units, it remains a necessary treatment option for preterm infants with a large hemodynamically significant PDA under strict clinical criteria, and it can reduce mortality in preterm infants. However, the optimal timing of surgical ligation is still controversial. We conducted this systematic review and meta-analysis to compare the mortality and morbidity of early and late surgical ligation of PDA in preterm or very-low-birth-weight (VLBW) infants.This review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42019133686). We searched the databases of PubMed, Embase, the Cochrane Central Register of Controlled Trials, and the World Health Organization International Clinical Trials Registry Platform up to May 2019.This review included 6 retrospective studies involving 397 premature or VLBW infants with PDA. Pooled analysis showed that compared with the late ligation group, the early ligation group had a lower fraction of inspired oxygen (FiO2) at 24 hours postoperatively (mean difference [MD] -6.34, 95% confidence interval [CI] -9.45 to -3.22), fewer intubation days (MD -19.69, 95% CI -29.31 to -10.07), earlier date of full oral feeding (MD -22.98, 95% CI -28.63 to -17.34) and heavier body weight at 36 weeks of conceptional age (MD 232.08, 95% CI 57.28 to 406.88). No significant difference in mortality or other complications was found between the early and late groups.Our meta-analysis implies that compared with late surgical ligation, early ligation might have a better respiratory outcome and nutritional status for PDA in preterm or VLBW infants. There was no difference in mortality or postoperative complications between early and late ligation. A randomized prospective clinical trial with a possible large sample size is urgently needed to reinvestigate this conclusion.CRD42019133686.
To investigate the effect of different operation time to percutaneous balloon pulmonic valvuloplasty (PBPV) to critical pulmonary valve stenosis (CPS).Twenty-one infants (age ≤ 60 days at operating day) suffered from CPS, diagnosed by fetal echocardiogram and confirmed by echocardiography after birth, were enrolled in this case-control-study with written informed consent during April 2007 to December 2011. Of the 21 cases, 7 had prenatal diagnosis in our prenatal diagnosis center (prenatal group, Pre) and 14 were referred from other hospitals, who were divided into postpartum group A (Post A, referred within 28 days after birth) and postpartum group B (Post B, referred 29 to 60 days after birth). To Pre-group, the integrative interventional protocol was cautiously made by the consultative specialists, including intrauterine diagnosis, perinatal care and urgent PBPV soon after birth. To Post-group, emergency PBPV was preformed after the referral. Tei index of right ventricular and pressure-gradient (PG) between right ventricular and pulmonary artery were measured before and at different time points one year after PBPV.The values of SpO2 in Pre-group ranged from 82%-92% (86.57% ± 5.34%) under the state of continuous intravenous infusion of alprostadil. PBPV was successfully preformed within 3-6 days after birth. The values of SpO2 increased to 97.33% ± 1.15% post procedure. The values of PG pre- and post- procedure were (86.34 ± 11.77) mm Hg and (31.43 ± 8.46) mm Hg respectively. Preoperative RV Tei-index was 0.68 ± 0.05, it decreased rapidly after procedure, and recovered to normal one month after procedure. Only one case showed restenosis seven months after procedure and repeated PBPV. Fourteen referral cases (6 cases in Post A group and 8 cases in Post B group, accompanied in 1 and 3 cases with heart failure), the values of SpO2 ranged from 83%-91% under state of continuous intravenous infusion of alprostadil. And the operating time was 10-57 days after birth. The values of SpO2 recovered to normal post procedure, and heart failure alleviated. Increased preoperative RV pressure obviously decreased significantly post-procedure. And increased Tei-index declined gradually, at one-year follow-up, the value of Tei-index in Post A group recovered to normal, whereas that of Post B was (0.51 ± 0.06), compared to Pre and Post A groups, the difference was significant (P < 0.05) . One case showed restenosis nine months after procedure and repeated PBPV was performed. The hypoxic exposure durations were (4.43 ± 0.68) , (16.33 ± 4.46) , (41.25 ± 9.19) , respectively, and the difference among the three groups was significant (P < 0.05).To the fetuses with definite prenatal diagnosis of critical pulmonary valve stenosis, preoperative general condition can be adjusted to more suitable for emergency operation. Early PBPV can achieve shorter hypoxic exposure and better recovery of right ventricular function post procedure. Perinatal integrated intervention for CPS can significantly improve the prognosis and quality of life in this patient population.
The prediction of resistance to intravenous immunoglobulins (IVIG) is currently still one of the main research areas in Kawasaki disease (KD). Several studies have reported on the use of N-terminal pro-brain natriuretic peptide (NT-ProBNP) to this end. However, considering the age-dependency of NT-ProBNP levels, age- specific NT-ProBNP cutoff levels to predict IVIG resistance in KD might be more precise and should be evaluated.A prospective cohort study with standardized data collection involving 393 KD patients aged 1 month to 125 months was conducted between June 2015 and April 2018. The demographic characteristics, clinical manifestations and laboratory data were compared between the patients responding to initial intravenous immunoglobulin (IVIG-response group) and those who did not (IVIG-resistance group). We further distinguished four subgroups according to patients' age (< 1 year, 1-2 years, 2-6 years, > 6 years). The cutoff values of NT-ProBNP for the prediction of IVIG resistance overall and in the subgroups were obtained using receiver operating characteristic (ROC) analysis.In all KD patients, the level of NT-ProBNP was significantly higher in the IVIG-resistance compared to the IVIG-response group (P = 0.006). This findings was similar in the subgroups except for patients older than six years. The best cutoff values of NT-ProBNP to predict IVIG resistance were 3755 pg/ml for all KD patients, 3710 pg/ml, 2800 pg/ml, 2480 pg/ml for those aged 2-6 years, 1-2 years and < 1 year, respectively. The corresponding sensitivities were 44.0, 52.2, 50.0 and 75.0%, while the specifities were 84.1, 86.3, 77.9 and 71.8%, respectively.NT-proBNP is a complementary laboratory marker for the prediction of IVIG resistance in KD patients, particularly for those younger than one year. Applying age-specific cutoff values is more precise than one value for all ages.

Myocardial infarction is one of the leading cause of cardiovascular death worldwide. Invasive interventional procedures and medications are applied to attenuate the attacks associated with ischemic heart disease by reestablishing blood flow and restoring oxygen supply. However, the overactivation of inflammatory responses and unsatisfactory drug delivery efficiency in the infarcted regions prohibit functional improvement. Here, a nanoengineered monocyte (MO)-based biohybrid system, referred to as CTAs @MOs, for the heart-targeted delivery of combinational therapeutic agents (CTAs) containing anti-inflammatory IL-10 and cardiomyogenic miR-19a to overcome the limitation of malperfusion within the infarcted myocardium through a polyphenol-mediated interfacial assembly, is reported. Systemic administration of CTAs@MOs bypasses extensive thoracotomy and intramyocardial administration risks, leading to infarcted heart-specific accumulation and sustained release of therapeutic agents, enabling immunomodulation of the proinflammatory microenvironment and promoting cardiomyocyte proliferation in sequence. Moreover, CTAs@MOs, which serve as a cellular biohybrid-based therapy, significantly improve cardiac function as evidenced by enhanced ejection fractions, increased fractional shortening, and diminished infarct sizes. This polyphenol nanoengineered biohybrid system represents a general and potent platform for the efficient treatment of cardiovascular disorders.
Abstract Rationale: Chronic thromboembolic pulmonary hypertension (CTEPH) is rare in children and determining the underlying etiologies is essential for treatment. Venous thromboembolism, a well-known complication in nephrotic syndrome (NS), always occurrs during the treatment in course of the disease. However, CTEPH as the first manifestation of NS has not been reported till now. Patient concerns: A 12-year-old boy initially complained of hemoptysis, cough and shortness of breath with exertion, any symptoms regarding NS such as edema were not presented. Due to the identification of P2 enhancement, liver enlargement (2 cm below the rib) and jugular vein distension, pulmonary hypertension (PH) was firstly suspected and ultimately confirmed by detection of enlargement of right atrium (RA) and right ventricle (RV) enlargement (RA = 45mm, RV = 30mm), mild tricuspid valve regurgitation (TR) and elevation of pulmonary arterial pressure (63 mmHg) on echocardiogram. In order to search the underlying causes of PH, series of targeted laboratory evaluation and imaging were conducted, and pulmonary arterial embolism (PE) in inferior lobes of double lungs was found on chest contrast-enhanced computed tomography. Diagnosis: NS was unexpectedly discovered by detection of lower serum albumin level (24.4 g/L), severe proteinuria (+++, 4.62 g/24 h) when we were searching for the predisposing factors causing thromboembolism. Interventions and outcomes: After treatment of NS, the symptom regarding shortness of breath with exertion gradually became less apparent and was relieved one month later. Proteinuria and microscopic hematuria also disappeared. Encouragingly, RA and RV dilation, and the pulmonary arterial pressure almost returned to a normal range half a year later, with alleviation of MR. Lessons: CTEPH can occur rarely in children and NS is an important predisposing factor. PE could be the first manifestation of NS. When pediatricians encounter children with PE or CTEPH, NS as the underlying etiology should be considered. Except for renal venous thrombosis, the possibility of PE needs to be paid more attention in children with NS.
The purpose of this study was to compare efficacy and side effects between oral propranolol combined with and without intralesional injection of lauromacrogol for infantile hemangioma (IH).
Background Kawasaki disease (KD) is an acute systemic vasculitis characterized by unknown etiology. Case summary A 4.5-year-old boy developed an acute abdomen during the onset of incomplete KD. He still had persistent abdominal pain after undergoing exploratory laparotomy and appendectomy. Ultrasound examination at early onset revealed a giant coronary artery aneurysm. The patient developed a myocardial infarction and heart failure accompanied by respiratory and cardiac arrest. He underwent coronary artery revascularization and coronary artery bypass graft using an autologous internal mammary artery. After the operation, the cardiac output increased, and the symptoms of heart failure resolved. Follow-up evaluation at 1 mo after operation showed that the patient's cardiac function had restored to New York Heart Association standard Grade I heart failure, and normal growth was obtained. Conclusion Coronary artery revascularization and coronary artery bypass graft is an effective method for treating myocardial ischemia in children with KD complicated with giant coronary artery aneurysm . Nevertheless, some issues still need specific attention.
