OBJECTIVETo analyze the comorbidities in patients with cerebral palsy (CP) from two perspectives as neurologic subtype and gross motor functions, and find their correlations.

METHODSChildren with cerebral palsy treated in the rehabilitation center from January 2007 to June 2009 received the following examinations: intelligence capacity test, ophthalmologic consultation, language-speech test, brainstem auditory evoked potential and electroencephalogram. They were stratified according to both neurologic subtype and gross motor functions to detect the occurrence of comorbidities.

RESULTSOf all the 354 cases, 166 (46.89%) had mental retardation, 15 (4.24%) auditory limitations, 138 (38.98%) visual disorder, 216 (61.02%) language-speech disorder and 82 (23.16%) epilepsy. The frequency of individual comorbidities were distributed disproportionately between the different neurologic subtypes. Correlation analysis showed that there was a significant correlation between the spastic diplegia and the visual disorder (correlation coefficient = 0.26), between spastic hemiplegia and epilepsy (correlation coefficient = 0.17), between spastic quadriplegia and epilepsy and mental retardation (the correlation coefficient was 0.38 and 0.11, respectively) and between both dyskinetic and mixed children and language-speech disorder (the correlation coefficient was 0.24 and 0.27, respectively). The frequency of individual comorbidities was distributed disproportionately between the different neurologic subtypes and between the different GMFCS levels (P < 0.05), except for the frequency of visual disorders (chi(2) = 1.90, P > 0.05); and with the increase of the GMFCS levels, the burden of the comorbidities were more heavy and the incidence of the comorbidities was higher. Multi-comorbidities were relatively infrequently encountered in those with spastic hemiplegic or spastic diplegic children or patients whose GMFCS levels were I-III, while these entities occurred at a frequent level for those with spastic quadriplegic, dyskinetic, or mixed or children whose GMFCS levels were IV and V, and the differences were significant (P < 0.05). The mean GMFCS levels of children with spastic quadriplegic, dyskinetic or mixed CP were higher than level III, most of them had no ability of ambulation;while the mean GMFCS levels of spastic hemiplegic or spastic diplegic children were below level III, most of them could walk independently.

CONCLUSIONSThere are correlations between the occurrence of the comorbidities such as mental retardation, auditory or visual impairments, language-speech disorders, epilepsy and the cerebral palsy subtype and the gross motor function levels. Clinicians should have a full recognition of these comorbidities, and we should have a cooperation between the different subjects to have an overall evaluation and rehabilitation and to improve the prognosis.

OBJECTIVEHuman cytomegalovirus (HCMV) is a ubiquitous human-specific DNA virus and is the main cause of congenital virus infection worldwide. Although 90% of the congenitally infected infants are clinically asymptomatic at birth, evidences show that these infants are at risk for audiologic, neurologic, and developmental sequelae. The aim of this study was to evaluate the outcome of children with asymptomatic congenital human cytomegalovirus infection identified from a cohort of newborn infants screened for congenital HCMV infection compared with matched uninfected control subjects.

METHODSBetween July 2003 and July 2005, eligible hospitalized infants were recruited into the cohort. Serum was collected within two weeks of birth and transported to the laboratory within 24 hours, and stored at -20 degrees C. Then Real-time fluorescent quantitative polymerase chain reaction (FQ-PCR) for the presence of HCMV DNA was used as a screening tool for the detection of congenital cytomegalovirus infection. Asymptomatic congenital HCMV infection (ACCMV) was defined as detection of HCMV during the first 2 weeks of life in the absence of any abnormal signs, symptoms, or laboratory findings. The study enrolled 41 siblings with asymptomatic congenital HCMV infection and 21 children whose neonatal screening for congenital HCMV infection showed negative results. Then they were followed up prospectively for the first years of life. A pediatric assessment, including neonatal behavioral neurological assessment (NBNA) was performed at neonatal period by a qualified pediatrician, at which time the CMV status of the infants was not yet known. At one year of age other standardised clinical evaluations were performed by the pediatrician. The Bayley scale of infant development were used to determine the intellectual and neurological development deficits, and the age-adequate neurological examinations based on the criteria by Amiel-Tison to evaluate the general movements for neurological development. Hearing screening were completed for all children to determine their hearing status. Auditory brain-stem response (ABR) and distortion product otoacoustic emission (DPOAE) have been used to accurately diagnose moderate to profound congenital sensorineural hearing loss.

RESULTThere was no significant difference between the mean NBNA score of HCMV group (38.8 +/- 2.75) and the control group (38.5 +/- 2.29) (t = 0.98, P > 0.05). Significant difference was found between the occurrence of hearing loss in infants born with asymptomatic congenital HCMV infection compared with the control group. Audiologic abnormalities (sensorineural hearing loss, SNHL) were present in 5 of 23 congenitally infected children, however, no hearing abnormalities were detected in uninfected children (chi2 = 6.94, P < 0.01). The mean Bayley score of HCMV group (MDI 106.86 +/- 10.24 and PDI 108.45 +/- 18.25) and the control group (MDI 107.49 +/- 19.31 and PDI 107.19 +/- 10.98) did not differ significantly (t = 0.33, P > 0.05, t = 0.35, P > 0.05). Otherwise, there was no significant difference in 52 Amiel-Tison neurological scale between the two groups.

CONCLUSIONThese data suggest that asymptomatic congenital cytomegalovirus infection may be associated with a broad range of audiologic differences in early infancy. Continued monitoring of their hearing status in the first years of life is necessary in these children because further progression of hearing loss is possible. However, asymptomatic congenital HCMV infection is not associated with abnormalities in growth, or neurodevelopmental deficits.

OBJECTIVETo study the value of serum S100B protein and neuron-specific enolase (NSE) levels in predicting the severity of hand, foot and mouth disease (HFMD).

METHODSNinety children with HFMD were classified into three groups: common type, severe type, and critical type (n=30 each). Thirty healthy children were randomly selected as the control group. ELISA was used to measure serum levels of S100B protein and NSE before and at 7 days after treatment. The receiver operating characteristic (ROC) curve was used to evaluate the prediction efficiency of S100B protein and NSE for the severity of HFMD.

RESULTSThe critical type group had significant increases in the serum levels of S100B protein and NSE compared with the other three groups (P<0.01). The severe type group had significant increases in serum levels of S100B protein and NSE compared with the common type and control groups (P<0.01). The critical type and severe type groups had significant reductions in serum levels of S100B protein and NSE after treatment (P<0.05). Serum S100B protein had the highest Youden value of 0.611 at the cut-off value of 0.445 μg/L, with a sensitivity of 61% and a specificity of 100%, in the prediction of serious HFMD (including severe type and critical type HFMD). Serum NSE had the highest Youden value of 0.533 at the cut-off value of 5.905 μg/L, with a sensitivity of 80% and a specificity of 73%, in the prediction of serious HFMD. Combined measurements of these two parameters had a sensitivity of 86% and a specificity of 73% and had the highest predictive value for serious HFMD.

CONCLUSIONSThe serum levels of S100B protein and NSE help to predict the severity and treatment outcomes of HFMD. Combined measurements of these two parameters has a higher predictive value for serious HFMD.

OBJECTIVETo evaluate the association between p53 codon 72 polymorphism (R72P) and the risk of colorectal liver metastases.

METHODSThe p53 R72P genotype was identified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 78 consecutive colorectal cancer patients with liver metastases and 214 age- and sex-matched cases with nonmetastatic colorectal cancer.

RESULTSThe R allele of the p53 R72P polymorphism was more frequently found in metastatic cases than in nonmetastatic cases (P=0.075). Carriers of the 72R allele had a 2.25-fold (95% CI (confidence interval)=1.05 to approximately 4.83) increased risk of liver metastases. On the stratification analysis, 72R-carrying genotype conferred a 3.46-fold (95% CI=1.02 to approximately 11.72) and a 1.05-fold (95% CI=0.36 to approximately 3.08) increased risk of liver metastases for p53 overexpression-positive and negative colorectal cancers, respectively.

CONCLUSIONThese results demonstrate for the first time that the 72R allele of the p53 polymorphism has an increased risk for liver metastases in colorectal cancers positive for p53 overexpression.

BACKGROUNDHypoxemic respiratory failure (HRF) is one of the most common causes for neonatal infants requiring aggressive respiratory support. Inhaled nitric oxide (iNO) has been established routinely as an adjunct to conventional respiratory support in developed countries. The aim of this study was to investigate effects of iNO in neonates with HRF in resource limited condition with no or limited use of surfactant, high frequency oscillatory ventilation (HFOV) and extracorporeal membrane oxygenation.

METHODSA non-randomized, open, controlled study of efficacy of iNO was conducted over 18 months. Eligible term and near-term neonates from 28 hospitals with HRF (oxygenation index > 15) were enrolled prospectively into two groups as either iNO or control. Oxygenation improvement and mortality as primary endpoint were determined in relation with dosing and timing of iNO, severity of underlying diseases, complications and burden. Intention-to-treat principle was adopted for outcome assessment. Response to iNO at 10 or 20 parts per million (ppm) was determined by oxygenation in reference to the control (between-group) and the baseline (within-group).

RESULTSCompared to 93 controls, initial dose of iNO at 10 ppm in 107 treated infants significantly improved oxygenation from first hour (P = 0.046), with more partial- and non-responders improved oxygenation with subsequent 20 ppm NO (P = 0.018). This effect persisted on days 1 and 3, and resulted in relatively lower mortalities (11.2% vs. 15%) whereas fewer were treated with surfactant (10% vs. 27%), HFOV (< 5%) or postnatal corticosteroids (< 10%) in both groups. The overall outcomes at 28 days of postnatal life in the iNO-treated was not related to perinatal asphyxia, underlying diseases, severity of hypoxemia, or complications, but to the early use of iNO. The cost of hospital stay was not significantly different in both groups.

CONCLUSIONSWith relatively limited use of surfactant and/or HFOV in neonatal HRF, significantly more responders were found in the iNO-treated patients as reflected by improved oxygenation in the first three days over the baseline level. It warrants a randomized, controlled trial for assessment of appropriate timing and long-term outcome of iNO.

OBJECTIVETo investigate the association between rs9722 polymorphisms in the S100B gene and hand, foot and mouth disease (HFMD) caused by enterovirus 71.

METHODSA total of 124 HFMD children with enterovirus 71 infection were enrolled as subjects, and 56 healthy children were enrolled as control group. The rs9722 polymorphisms in the S100B gene were detected for both groups, and the serum level of S100B protein was measured for 74 HFMD children.

RESULTSThe rs9722 locus of the S100B gene had three genotypes, CC, CT, and TT, and the genotype frequencies were in accordance with Hardy-Weinberg equilibrium. Compared with the control group, the HFMD group had significant increases in the frequencies of TT genotype and T allele (P<0.01). Children with severe HFMD caused by enterovirus 71 infection had significantly higher frequencies of TT genotype and T allele than those with moderate or mild HFMD (P<0.05). Compared with the cured patients, the patients with poor prognosis had significant increases in the frequencies of TT genotype and T allele in the rs9722 locus of the S100B gene (P<0.05). Among the 74 children with HFMD, the children with TT genotype had the highest serum level of S100B protein, and those with CC genotype had the lowest level (P<0.01).

CONCLUSIONST allele in the rs9722 locus of the S100B gene might be a risk factor for severe HFMD caused by enterovirus 71 infection.

OBJECTIVE: To study the association of different stages of histological chorioamnionitis (HCA) with the incidence rate and severity of respiratory distress syndrome (RDS) in preterm infants. METHODS: Related data were collected from the infants and their mothers who were treated in the Neonatal Intensive Care Unit of Qingdao Women and Children's Hospital, Qingdao University, from January 2018 to June 2020. According to the presence or absence of HCA and its stage, the infants were divided into four groups: control ( RESULTS: Compared with the control and late-stage HCA groups, the early-stage HCA group had a significantly lower incidence rate of placental abruption and a significantly higher rate of prenatal use of antibiotics ( CONCLUSIONS Early-, middle-, and late-stage HCA can reduce the incidence rate of RDS in preterm infants. HCA stage may not be correlated with RDS severity in preterm infants, which needs to be verified by further research.

OBJECTIVE: To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants. METHODS: The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP. RESULTS: The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation ( CONCLUSIONS A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.

METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.

RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.

CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.
