ABSTRACT
Bloodstream infections (BSIs) after chemotherapy or hematopoietic stem cell transplantation (HSCT) are a leading cause of morbidity and mortality. Data on 154 BSIs that occurred in 111 onco-hematological patients (57 hematological malignancies, 28 solid tumors, and 26 non-malignant hematological diseases) were retrospectively collected and analyzed. Monomicrobial Gram-positive (GP), Gram-negative (GN), and fungal BSIs accounted for 50% (77/154), 38.3% (59/144), and 3.2% (5/154) of all episodes. Polymicrobial infections were 7.8% (12/154), while mixed bacterial-fungal infections were 0.6% (1/154). The most frequent GN isolates were Escherichia coli (46.9%), followed by Pseudomonas aeruginosa (21.9%), Klebsiella species (18.8%), and Enterobacter species (6.3%). Overall, 18.8% (12/64) of GN organisms were multidrug-resistant (seven Escherichia coli, three Klebsiella pneumoniae, and two Enterobacter cloacae), whereas GP resistance to glycopeptides was observed in 1% (1/97). Initial empirical antibiotic therapy was deemed inappropriate in 12.3% of BSIs (19/154). The 30-day mortality was 7.1% (11/154), while the bacteremia-attributable mortality was 3.9% (6/154). In multivariate analysis, septic shock was significantly associated with 30-day mortality (p = 0.0001). Attentive analysis of epidemiology and continuous microbiological surveillance are essential for the appropriate treatment of bacterial infections in pediatric onco-hematological patients.
ABSTRACT
BACKGROUND: Growth monitoring is an essential part of primary health care in children and short stature is frequently regarded as a relatively early sign of poor health. The association of short stature and dysmorphic features should always lead to exclude an underlying syndromic disorder. CASE PRESENTATION: We report the case of an Indian school-aged boy with dysmorphic features, intellectual disability and a clinical history characterized by seizures and hearing problems. Although his height was always included in the normal range for age and sex throughout childhood, he presented a short near-adult stature in relation to his mid-parent sex-adjusted target height. This is probably due to a rapidly progressive pubertal development. CONCLUSIONS: In the presence of characteristic dysmorphic features, intellectual disability, seizures and hearing problems, KBG syndrome should always be considered. This emergent condition presents a wide spectrum of clinical phenotypes and is often associated with adult short stature.

PURPOSE OF REVIEW: This review summarizes the most recent evidence regarding the effects of micronutrients on brain development. RECENT FINDINGS: Emerging evidence indicates that nutrition in the early life can profoundly influence neurodevelopment, affecting later life health outcomes, neurocognitive performances, and disease risks. Inadequate early life nutrition has been associated with some neuropsychiatric disorders. Epigenetic mechanisms could play a crucial role, imprinting the genomes in early life making the individual more susceptible to develop diseases later in life. Children adequately nourished are more likely to reach their developmental potential in cognitive, motor, and socioemotional abilities, with positive societal repercussions. Data from further clinical trials are needed before more definitive conclusions can be drawn regarding the efficacy of dietary interventions for improving neurocognitive and social outcomes and preventing some neuropsychiatric illnesses. Nevertheless, it is reasonable to make recommendations to our patients to adopt certain dietary habits to optimize early life nutritional status in order to avoid long-term adverse consequences. Strategies of prevention should focus on ensuring more quality food to preconceptional, pregnant, lactating women and to children in their early life, not only in those areas where malnutrition is common but also in developed countries.
