RESUMO
OBJECTIVES@#To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China.@*METHODS@#A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined.@*RESULTS@#The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05).@*CONCLUSIONS@#It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Metabolic bone disease of prematurity (MBDP) is a systemic bone disease with a reduction in bone mineral content due to disorder of calcium and phosphorus metabolism. There is still a lack of in-depth research and systematic understanding of MBDP in China, and there are many irregularities in clinical management of this disease. Based on relevant studies in China and overseas, Grading of Recommendations Assessment, Development and Evaluation was used to develop the expert consensus on the clinical management of MBDP, which provides recommendations from the following five aspects: high-risk factors, screening/diagnosis, prevention, treatment, and post-discharge follow-up of MBDP, so as to provide relevant practitioners with recommendations on the clinical management of MBDP to reduce the incidence rate of MBDP and improve its short- and long-term prognosis.

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.

Inadequate nutrition supply in the early stage after birth is a risk factor for the development of bronchopulmonary dysplasia (BPD) in preterm infants, and it is also closely associated with the progression and clinical outcome of BPD. Optimized nutritional support is of great importance to reduce the incidence and severity of BPD and promote lung development and neurological prognosis. Based on the relevant studies in China and overseas, the expert consensus on BPD nutrition management is developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method. The consensus includes the following seven aspects: the importance of nutrition in BPD, fluid intake, energy intake, enteral nutrition, parenteral nutrition, post-discharge nutrition, and nutrition monitoring and evaluation.

A female infant was admitted to the hospital due to perioral cyanosis two hours after birth. The infant was born at the gestational age of 35 weeks by cesarean section with a birth weight of 2 400 g. Physical examination revealed wry mouth to the left side while crying, small auricles, and high palatal arch; fibrolaryngoscopy suggested bilateral vocal cord paralysis; echocardiography suggested ventricular septal defect; single nucleotide polymorphism testing showed 22q11.21 microdeletion. Therefore, the infant was given a definite diagnosis of asymmetric crying facies syndrome accompanied by 22q11.21 microdeletion. After 8-month follow-up, the infant still had asymmetric crying facies with presence of growth retardation.

A boy, aged 5 years, was admitted due to chest pain for 4 months, right lower limb weakness for 2 months, and weakness of both lower limbs for 10 days. There were no symptoms of defecation/urination disorders or disturbance of consciousness, and the boy had upper motor neuron paralysis in both lower limbs, without cranial nerve involvement or sensory disorder. Spine magnetic resonance imaging revealed tumor in the spinal canal between cervical vertebra 6 and thoracic vertebra 2, which put pressure on the spinal cord. He was transferred to the department of neurosurgery for surgical treatment and fully recovered after tumor resection, and no recurrence was observed after 6 years of follow-up. The pathological diagnosis was clear cell meningioma (WHO grade II). For children with chest pain and dyskinesia, spinal meningioma should be considered.

Objective To assess the efficiency of synchronized nasal intermittent positive pressure ventilation (SNIPPV) as a transitional mode in treatment of neonatal respiratory distress syndrome (RDS) after extubation.Methods In this single-center and randomized controlled trial,preterm infants (gestational age less than 35 weeks)with RDS who received mechanical ventilation were randomly assigned to receive SNIPPV(33 cases) or NCPAP(34 cases) after extubation.Blood gas analysis,prevalence of extubation failure and complications were compared between the 2 groups.Results The Pa (O2) in SNIPPV group was significantly higher but the pa (CO2) was significantly lower than those in the NCPAP group at 3 h and 12 h after extubation respectively(all P < 0.05).Infants treated with SNIPPV had a decreased incidence of hypoxemia,hyperbicarbonatemia and extubation failure compared with those of patients treated with NCPAP (all P < 0.05).SNIPPV group had a decreased incidence of apnea (P =0.000),shorter duration of mechanical ventilation and oxygen treatment duration than those of NCPAP group (all P < 0.05).Conclusions SNIPPV is superior to NCPAP in serving as a transitional mode after extubation for preterm infants with RDS,and should be used in preference after extubation.
RESUMO
<p><b>OBJECTIVE</b>To understand the prognosis of the children with urinary calculi associated with exposure to melamine-contaminated formula.</p><p><b>METHODS</b>A follow-up study was performed in 47 out-patients from the Third Hospital of Peking University who were diagnosed with urinary calculi associated with exposure to melamine-contaminated formula. Urinary tract B-ultrasound and renal function examinations were done during the 1 to 6-month follow-up.</p><p><b>RESULTS</b>By the 6th month of follow-up, spontaneous stone passage was found in 36 children (77%). The follow-up failed in four children. None of the patients had any complications. Spontaneous stone passage was not associated with the volume and the period exposed to melamine in formula, but was associated with the location of calculi. The time to spontaneous stone passage in boys appeared to be longer than in girls, but there were no statistical differences.</p><p><b>CONCLUSIONS</b>Spontaneous stone passage can be found in most children and the prognosis of children with urinary calculi associated with exposure to melamine-contaminated formula is good.</p>

A 13-year-old girl presented with a 1-month history of progressive exertional dyspnea (NYHA class IV) and exophthalmos for 6 months. She had a history of long-standing asthma and the presence of allergy. Hypereosinophilia and increased serum IgE levels (2472 IU/mL) were observed. Chest radiography and a high resolution CT scan documented a massive interstitial pulmonary infiltration. Echocardiography confirmed mild tricuspid regurgitation, apical obliteration of the right ventricle by fibrocalcific thickening of the endocardium and echogenic material suggestive of thrombosis. Churg-Strauss syndrome with cardiac involvement (endomyocardiopathy) was diagnosed. The patient received anticoagulation and corticosteroid therapy. In view of rapidly progressive severe endomyocardiopathy and stable hematology, the patient was referred for cardiac surgery. Histopathological examination of resected specimens confirmed laminated thrombus but without any trace of eosinophils embedded.
