Infantile hemangiomas are the most common benign vascular tumors in children. They present a characteristic natural history of spontaneous involution after a phase of initial proliferation. A small but significant minority demonstrates incomplete regression or complications and requires prompt intervention. Prediction of the evolution of infantile hemangiomas is challenging because of their morphological and behavioral heterogeneity. The decision between referral for treatment and observation is sometimes difficult, especially among non-expert physicians, with the risk of missing the period for optimizing outcomes in case of delayed intervention. The aim of this review is to update our knowledge, especially of the primary care providers, regarding the ongoing difficulties of the early clinical evaluation of infantile hemangiomas, and to outline the importance of current practical scoring tools for the identification of the lesions which require expert consultation and referral.

Importance: Despite the high burden of respiratory infections among children, the production of exhaled particles during common activities and the efficacy of face masks in children have not been sufficiently studied.
Objective: To determine the effect of type of activity and mask usage on exhaled particle production in children.
Methods: Healthy children were asked to perform activities that ranged in intensity (breathing quietly, speaking, singing, coughing, and sneezing) while wearing no mask, a cloth mask, or a surgical mask. The concentration and size of exhaled particles were assessed during each activity.
Results: Twenty-three children were enrolled in the study. Average exhaled particle concentration increased by intensity of activity, with the lowest particle concentration during tidal breathing (1.285 particles/cm3 [95% CI 0.943, 1.627]) and highest particle concentration during sneezing (5.183 particles/cm3 [95% CI 1.911, 8.455]). High-intensity activities were associated with an increase primarily in the respirable size (≤ 5 µm) particle fraction. Surgical and cloth masks were associated with lower average particle concentration compared to no mask (P = 0.026 for sneezing). Surgical masks outperformed cloth masks across all activities, especially within the respirable size fraction. In a multivariable linear regression model, we observed significant effect modification of activity by age and by mask type.
Interpretation: Similar to adults, children produce exhaled particles that vary in size and concentration across a range of activities. Production of respirable size fraction particles (≤ 5 µm), the dominant mode of transmission of many respiratory viruses, increases significantly with coughing and sneezing and is most effectively reduced by wearing surgical face masks.

Professor Dong graduated from the Medical College of Fudan University (formerly Shanghai First Medical College) with excellent grades in 1956. Then he worked at Zhongnan Tongji Medical College (now Tongji Medical College of Huazhong University of Science and Technology) and its affiliated Wuhan Tongji Hospital. He soon became the backbone of the college and was responsible for establishing the Department of Pediatrics. With the aspiration of being “a good physician, a good teacher, and a good scholar”, Professor Dong strived to be progressive and comprehensive in clinical practice, teaching, and scientific research. He had devoted his whole life to safeguarding children’s health, developing pediatrics, and cultivating excellent pediatricians in China.

Importance: Urinary tract infection (UTI) is one of the most common infections encountered in infancy and childhood. Despite the emerging problem of antibiotic resistance in recent years, the use of antibiotics for better management of UTIs is inevitable.
Objective: This study aims to explore the efficacy and adverse effects of the available antimicrobial agents that are used in pediatric UTIs in low- and middle-income countries (LMICs).
Methods: Five electronic databases were searched to identify relevant articles. Two reviewers independently performed screening, data extraction, and quality assessment of the available literature. Randomized controlled trials providing antimicrobial interventions in both male and female participants within the age range of 3 months to 17 years in LMICs were included.
Results: Six randomized controlled trials from 13 LMICs were included in this review (four trials explored the efficacy). Due to high heterogeneity across the studies, a meta-analysis was not performed. Other than attrition and reporting bias, the risk of bias was moderate to high due to poor study designs. The differences in the efficacy and adverse events of different antimicrobials were not found to be statistically significant.
Interpretation: This review indicates the necessity for additional clinical trials on children from LMICs with more significant sample numbers, adequate intervention periods, and study design.

Importance: Preserving skin health is crucial for atopic dermatitis control as well as for the thriving of children. However, a well-developed and validated tool that measures the knowledge, attitude, and practice of skin care is lacking.
Objective: To develop and validate the atopic dermatitis and infant skincare knowledge, attitude, and practice (ADISKAP 1.0) scale that measures parental health literacy on atopic dermatitis and skin care.
Methods: We conducted a review of the literature, a focus group (two dermatologists and 12 parents), and a panel discussion in order to generate the ADISKAP prototype. Two samples of parents with knowingly superior (dermatologists, n = 59) and inferior (general population, n = 395) knowledge traits participated in the validation of ADISKAP. Cronbach's alpha was reported as a measure of internal consistency, and the intraclass correlation coefficient (ICC) was calculated to assess the test-retest validity. The known-groups technique was used to evaluate construct validity.
Results: The ADISKAP scale contained 17 items after content and face validity validation. After removing items that displayed poor test-retest reliability (n = 4) and construct validity (n = 3), 12 items were retained in the ADISKAP 1.0.
Interpretation: ADISKAP 1.0 is a reliable and valid tool for assessing parental knowledge, attitude, and practice on infantile atopic dermatitis and skin care.

Introduction: Haemophilus influenzae (Hi) is subdivided into typeable (a-f) and non-typeable groups. Hi serotype b (Hib) has historically been one of the important pathogens responsible for invasive infection. However, after widespread Hib vaccination, the emergence of other Hi serotypes, specifically Hi serotype a (Hia), was noted during the last few decades, mostly in children younger than 5 years of age.
Case presentation: We present two cases of severe intracranial infections with detected Hia in patients > 5 years of age within a short time frame and within the same geographic area.
Conclusion: Epidemiological studies and surveillance on Hia-related illnesses in all age groups worldwide are needed to better understand the clinical and epidemiological characteristics of Hia. This can establish a platform to develop a candidate vaccine against Hia that might protect children of all ages.
导言:流感嗜血杆菌(Hi)又分为可分型(a-f)和不可分型两类。血清型 b 型流感嗜血杆菌(Hib)一直是造成入侵性感染的重要病原体之一。然而,在广泛接种 Hib 疫苗后,过去几十年中出现了其他 Hi 血清型,特别是 Hi 血清型 a(Hia),主要发生在 5 岁以下儿童中:病例介绍:我们介绍了两例颅内严重感染病例,患者年龄均大于 5 岁,且在短时间内和同一地理区域内检测到 Hia:为了更好地了解 Hia 的临床和流行病学特征,有必要对全球所有年龄组的 Hia 相关疾病进行流行病学研究和监测。结论:需要对全球所有年龄组的 Hia 相关疾病进行流行病学研究和监测,以更好地了解 Hia 的临床和流行病学特征,从而为开发可保护所有年龄组儿童的 Hia 候选疫苗建立一个平台。
