Objectives: This review focuses on the role of anti-neutrophil antibodies in neonatal and pediatric neutropenias with particular regard to laboratory tests useful to detect them. Background: Neutropenia is a common medical problem for infants and children that can predispose them to the risk of bacterial infections. There are many causes for pediatric neutropenia, but at birth and for the first years of life, neutropenia is often attributable to immune mechanisms, either by the presence of auto or alloantibodies directed against human neutrophil antigens (HNA). The detection of these antibodies is a useful diagnostic tool to define immune-mediated neutropenia, which includes a variety of clinical conditions. Methods: PubMed was used to carry out a literature search for the last 10 years. In addition, pivotal papers on this topic, before 2010, were also considered. Conclusions: The detection and identification of anti-neutrophil antibodies with the techniques currently available are often laborious, difficult, and performed in specialized laboratories. Moreover, since neutrophils are fragile cells and difficult to preserve, several advances in laboratory procedures have been developed in the last years. The recent availability of new commercial assays, which do not require fresh cells, may represent an important step forward in neutrophil serology, as it could improve the standardization and availability of serological and genomic tests that can also be used in non-specialized laboratories. However, these assays still need to complete the necessary validations before replacing classical serological methods. 13

Background: To explore the clinical, histological, and molecular characteristics of childhood medulloblastoma (MB) and its prognosis. Methods: The authors analyzed clinical and pathological data from MB patients at Children’s Hospital of Soochow University who were diagnosed by pathology after surgical resection between November 2011 and October 2020. Results: A total of 40 patients were considered (20 males and 20 females), where the median age at MB onset was 81 months (5–163 months). Of these, complete resection was performed for 26 cases (26/40, 65%) and subtotal resection performed for 14 cases (14/40, 35%). Pathology after resection indicated that in 8 cases the MB had already metastasized. All 40 children were histologically classified, identifying: 32 cases of classic type (32/40, 80%), 6 cases of desmoplastic/nodular type (6/40, 15%), and 2 cases of anaplastic type (2/40, 5%). Molecular typing tests were performed on 19 children, identifying: 1 case in the wingless-activated (WNT-activated) group (1/19, 5.3%), 6 cases in the sonic hedgehog-activated (SHH-activated) group (6/19, 31.6%), 7 cases in Group 3 (7/19, 36.8%), and 5 cases in Group 4 (5/19, 26.3%). Of the 40 patients, 29 received a combined treatment of surgery, radiotherapy, and chemotherapy, and the median follow-up time was 25 months (1–102 months). The 3-year overall survival rate (OS) and event-free survival rate (EFS) were (64.3±10.4)% and (61.8±10.3)%, respectively. Univariate analyses showed that age, clinical stage, pathological subtype, and radiotherapy were potentially relevant variables in patient prognosis (P<0.05). Cox regression analysis showed that age and tumor metastasis were independent risk factors for poor prognosis of children with MB (P<0.05). Conclusions: Metastasis and age at initial diagnosis are unfavorable factors in the prognosis of childhood MB patients; however, radiotherapy could improve the prognosis of MB patients. 8

Objective: To provide a narrative review of the current outcomes and future trends in paediatric and congenital cardiac surgery in a historical and multidisciplinary context. To present the paradigm shift in treating congenital heart disease that translate into improved outcomes. To identify current problems with directions of research. Background: Congenital heart disease (CHD) is the most common birth defect affecting approximately 1 neonate in every 120–166 births. More than half of CHD-patients need cardiac surgery in their lifetime; and half of the surgeries are required within the first six months of life. Methods: Narrative overview of the literature combining with current outcome data available from international databases is presented in comparison to the programme development of a newly-established tertiary-care centre. Conclusion: Congenital cardiac surgery is reconstructive surgery that aims for restoring biventricular circulation, when possible. Single-stage primary complete repair has become the central philosophy since the 1980s. In about thirty percent, physiologic and anatomical reasons do not permit repair by a single operation; these patients endure staged-repairs. Another 15% of CHD patients will require subsequent reoperations— mostly re-replacements of non-growing and/or deranged prostheses. Owing to advances of multidisciplinary treatment, CHD survival to adulthood now reaches 90–95% in high-income countries from less than 20% in the presurgical era. Treating CHD patients is a commitment for life. Research for viable and growing prostheses may solve the significant public health aspects currently associated with reoperations.

Background: Medulloblastoma (MB) is the most common malignant pediatric brain tumor. This study systematically summarized the clinical characteristics and prognosis of children with MB respectively. Univariate survival analysis identified age <3 years and the absence of radiotherapy as poor prognostic factors (both P<0.05). Conclusions: Survival outcomes were good among patients with MB (MB) in our center. Young age and the omission of radiotherapy may be predictive of poor outcomes.

A hospital-dedicated human milk bank was established in Japan at Koto Toyosu Hospital, Showa University in 2014. After a 3-year trial-and-error period, the Japanese Human Milk Bank Association was established in 2017. The supply of donor human milk (DHM) from the Japanese Human Milk Bank Association to various facilities nationwide has increased recently. However, as of 2021, there is only one human milk bank in Japan and the supply is limited. Therefore, there is an urgent need to understand the status of usage of DHM in the neonatal intensive care unit. Moreover, it is globally rare to build a database aimed at understanding the background and prognosis of all children supplied with DHM. In this paper, we have introduced the database and reported on aspects such as the salient points considered in building this database. The fundamental policy of this database included the following: (I) accessibility from the neonatal intensive care unit, (II) a simple input method, (III) reliability and continuity, (IV) safeguarding anonymity, (V) enriched search functionality, and (VI) enabling administration by the person in charge at each facility. In accordance with these six policies, the main items such as patient clinical information, DHM usage amount, and prognosis were set. In addition, the database was built to enable detailed search. The database was completed and became operational in November 2020. The input format was simplified as much as possible by adopting a selection-from-options approach. Enriched search functionality was implemented considering the function as a database in each facility. This database has enabled the proper operation of the human milk bank, and it would likely contribute further to perinatal care outcomes.
