Periorbital necrotizing fasciitis (NF) is a devastating bacterial infection associated with irreversible inflammatory destruction of soft tissues. Outcomes include disfigurement, vision loss, septic shock, and death within hours to days. We describe two cases of periorbital NF that presented to our unit within a three-month period.

However, a major drawback of telomerase inhibition is that it affects cancer cell proliferation only when telomeres shorten, creating a lag phase post-continuous drug treatment. Acute cytotoxicity of telomerase inhibitors is dependent on their ability to induce DNA damage.

Recently, comorbid sleep deficits have been highlighted in these disorders, with sleep repair a potential therapeutic target. Animal models of FASD have shown non-REM (NREM) sleep fragmentation and slow-wave oscillation impairments that predict cognitive performance.

Methods: This is a Retrospective review of series of annual audits. All involutional/aponeurosis-disinsertion ptosis surgeries performed at Moorfields Eye-hospital (MEH) between January 01, 2016 and December 31, 2019 were included.
Although health and health care disparities between immigrant and native-born adult populations in the United States are well documented, the pediatric literature is limited. Data suggest first- and second- generation immigrant children have worse health outcomes when compared with their native-born counterparts because of factors such as socioeconomic status, insurance and language barriers, authorization status, and bias/xenophobia. This article takes a broad look at existing research regarding health barriers for immigrant children, then focuses on the pediatric epilepsy literature to highlight the complex interplay of these disparity factors.

Methods: Sample included 1200 late preterm infants (LPIs) from the Early Childhood Longitudinal Study, Birth Cohort. Objective measurements of development at 9 and 24 months (Bayley-SFR) and reading and math academic achievement at preschool and kindergarten were standardized; trajectories of late preterm development from 9 months to kindergarten reading and math were identified using latent class growth analysis.
The study investigated the emergence of toddlers' regulatory strategies in aversive contexts. Forty-two toddlers were observed at 24 and 30 months of age using two paradigms designed to elicit fear and anger. We examined toddlers' use of regulatory strategies at these two stages of life regarding the frequency of self-versus other-oriented strategies and of reactive versus more controlled behaviors.

Our previous work found a positive association between higher curiosity and higher academic achievement at kindergarten, with a greater magnitude of benefit for children with socioeconomic disadvantage. Because characteristics of the early caregiving and physical environment impact the processes that underlie early learning, we sought to examine early environmental experiences associated with early childhood curiosity, in hopes of identifying modifiable contexts that may promote its expression.

RV's function is supposed to be the strong prognostic factor for patients diagnosed with congenital heart defects; therefore, assessing it is the main objective of the study.
Methods: This is a prospective single-centered cohort study performed on 50 pediatric patients with congenital heart disease (CHD) who underwent ICR between January 2019 and January 2022.
Learning and memory storage is a complex process that has proven challenging to tackle. It is likely that, in nature, the instructive value of reinforcing experiences is acquired rather than innate. The association between seemingly neutral stimuli increases the gamut of possibilities to create meaningful associations and the predictive power of moment-by-moment experiences.

Methods: Retrospective case series of primary BCC treated with surgical excision (Mohs micrographic surgery [MMS], wide local excision [WLE] or fast paraffin excision) who have histologically-confirmed BCC subtype and histologically-measured tumour clearance margins.
Results: 77 patients (78 eyelids) were included.
Infant-directed speech (IDS), the particular form of spontaneous language observed in interactions between parents and their infants, is a crucial aspect of the mother-infant interaction and an index of the attunement of maternal linguistic input to her infant communicative abilities and needs during dyadic interactions. The present study aimed to explore linguistic and pragmatic features of IDS during mother-infant interactions at 3-month of infant age. The effects of infant (birth status: preterm vs.

We report findings from two pilot studies conducted in the United States that describe the reliability and validity of a relational health screening tool, the Early Relational Health Screen (ERHS), implemented in two different contexts: an innovative model of relational health promotion in pediatric primary care (Study 1) and an Infant Mental Health Home Visiting (IMH-HV) model (Study 2). Across both studies, a trained clinician rated the ERHS following real-time observation of interaction (i.

This prospective longitudinal study examined patterns of mean-level continuity and individual-differences stability of select scales of temperament at 6 and 12 months in preterm infants from three countries, Chile (n = 47), United Kingdom (n = 44), and United States (n = 50). Temperament was assessed with the Infant Behavior Questionnaire and observed using the Bayley Behavior Rating Scale.

The amygdala complex plays an important role in recognition of, and response to, hedonically valenced stimuli, and has strong, reciprocal connectivity with the primary olfactory (piriform) cortex. Here, we used differential odor-threat conditioning in rats to test the role of basolateral amygdala (BLA) input to the piriform cortex in acquisition and expression of learned olfactory threat responses.

Study Design: Sample included 5100 children from the Early Childhood Longitudinal Study, Birth Cohort. Hours of daily television exposure and frequency of parent screen-time conversation were assessed from a parent interview at preschool, and the outcome of early childhood curiosity was derived from a child behavior questionnaire at kindergarten.
Objective: The goal of this study was to test the impact of maternal adverse childhood experiences (ACEs) on subsequent child language competence; higher parental ACEs were expected to predict risk of toddler language delay. Participation in Infant Mental Health Home Visiting (IMH-HV) treatment, which aims to enhance responsive caregiving and improve child social-emotional development, was expected to mitigate this association.
Methods: A randomized controlled trial (RCT) design was used.

DNA's integrity is continuously challenged by intrinsic cellular processes and environmental agents. To overcome this genomic damage, cells have developed multiple signalling pathways collectively named as DNA Damage Response (DDR) and composed of three components: (i) sensor proteins, which detect DNA damage, (ii) mediators that relay the signal downstream and recruit the repair machinery and (iii) the repair proteins, which restore the damaged DNA. A flawed DDR and failure to repair the damage lead to the accumulation of genetic lesions and increased genomic instability, which is recognized as a hallmark of cancer.

It offers several unique advantages as it allows fast, relatively quantitative, multiparametric analysis of cell populations at the single cell level. In addition, it also enables physical sorting of the cells to separate the subpopulations based on different parameters.
