The effect of multiple general anesthesia (mGA) procedures administered in early life is a critical theme and has led the Food and Drug Administration (FDA) to issue an alert. This systematic review seeks to explore the potential effects on neurodevelopment of mGA on patients under 4 years. The Medline, Embase and Web of Science databases were searched for publications up to 31 March 2021. The databases were searched for publications regarding "children multiple general anesthesia OR pediatric multiple general anesthesia". Case reports, animal studies and expert opinions were excluded. Systematic reviews were not included, but they were screened to identify any possible additional information. A total of 3156 studies were identified. After removing the duplicates, screening the remaining records and analyzing the systematic reviews' bibliography, 10 studies were considered suitable for inclusion. Comprehensively, a total cohort of 264.759 unexposed children and 11.027 exposed children were assessed for neurodevelopmental outcomes. Only one paper did not find any statistically significant difference between exposed and unexposed children in terms of neurodevelopmental alterations. Controlled studies on mGA administered before 4 years of age support that there might be a greater risk of neurodevelopmental delay in children receiving mGA, warranting the need for careful risk/benefit considerations.

Primary cutaneous lymphoproliferative disorders are a composite group of diseases with considerable differences in histopathologic, immunophenotypic, and clinical features. They are exceedingly rare in children and in the literature only few cases are reported with extremely different therapeutic approaches. Because of the rarity of cutaneous lymphomas we consider crucial to increase the knowledge of these diseases providing every single case. We present 3 pediatric cases of primary cutaneous T-cell lymphomas occurred to our center with different features and therapeutic approach.

Background: Invasive fungal infection (IFI) is a cause of morbidity, mortality and increased health costs in children undergoing chemotherapy or hematopoietic stem cell transplant (HSCT)., Methods: Multicenter, retrospective study to assess the incidence, outcome of proven and probable IFI (PP-IFI) in children treated for acute leukemia, non-Hodgkin lymphoma or who underwent HSCT from 2006 to 2012., Results: Over the 7-year period, 127 PP-IFI were diagnosed in 123 patients, median age of 9.7 years. The 1-year cumulative incidence was 2.5% (CI 1.8-3.7) after frontline chemotherapy, 9.4% (CI 5.8-15.0) after relapse, and 5.3% (CI 3.9-7.1) after HSCT. Severe neutropenia was present in 98 (77%) patients. Culture-proven agents were Candida spp., mostly non-albicans, 28, mold 23, whereas three proven IFI were identified by histopathology. Favorable response to treatment within 3 months from diagnosis was observed in 77 (89%). The overall ninety-day probability of survival was 68% (CI 59-76)., Conclusions: About two-thirds of pediatric patients with PP-IFI survived, regardless of whether the infection occurred after frontline chemotherapy, reinduction chemotherapy for disease relapse, or after HSCT. Further prospective studies are needed to define the impact of antifungal prophylaxis and early combination therapy on short-term overall survival., (© 2017 John Wiley & Sons A/S.

Background: Rosai-Dorfman disease (RDD) is a rare form of histiocytosis characterized by histiocyte proliferation within lymph nodes and extranodal tissue. Here we report an unusual presentation of RDD in an Italian toddler. Moreover, we reviewed the pediatric case reports published between 2004 and 2014, focusing in particular on medical therapy., Case Presentation: We report the case of a 14-month-old child who developed a progressive swelling of the right parotid, associated with systemic symptoms and abnormal blood tests. During diagnostic work-up, cervical, intraparotid, and unilateral hilar lymphadenopathies were found. Histopathological and immunohistochemistry studies of a cervical lymph node biopsy established the diagnosis of RDD, with positive PCR for Epstein - Barr virus on the biopsy specimen. Oral steroid therapy was started with progressive reduction in size of all lesions, resolution of systemic symptoms, and normalization of blood tests., Conclusion: RDD is generally considered a benign and self-limiting form of histiocytosis, usually associated with favorable prognosis. However, complications are not infrequent and fatal cases were reported even in children. Efforts should be made to establish the best therapeutic strategy for this disease, as no well-defined guidelines exist. Finally, RDD should be included in differential diagnosis of lymphadenopathy and parotid swelling even in very young children.

Objectives: Because of the spread of drug-resistant Gram-positive bacteria, the use of linezolid for treating severe infections is increasing. However, clinical experience in the paediatric population is still limited. We undertook a multicentre study to analyse the use of linezolid in children., Methods: Hospitalized children treated with linezolid for a suspected or proven Gram-positive or mycobacterial infection were analysed retrospectively. Side effects were investigated, focusing on younger children and long-term treatments., Results: Seventy-five patients (mean age 6.8 years, range 7 days to 17 years) were studied. Mean ± SD linezolid treatment duration was 26.13 ± 17 days. Clinical cure was achieved in 74.7% of patients. The most frequent adverse events were diarrhoea and vomiting. Two patients had severe anaemia, two neutropenia and one thrombocytopenia. Two cases of grade 3 liver function test elevation and one case of pancreatitis were reported. The overall frequency of adverse events was similar between patients treated for >28 days and those receiving shorter treatments (30.8% versus 28.6%, P = 0.84). Children aged <2 years received linezolid for a shorter duration than older children (21.2 days versus 28.4 days, P = 0.05), whereas the frequency of adverse events was similar in the two age groups., Conclusions: In our paediatric population, linezolid appeared safe and effective for the treatment of selected Gram-positive and mycobacterial infections. The adverse reactions encountered were reversible and appeared comparable to those reported in paediatric clinical trials. Nevertheless, the potential for haematological toxicity of linezolid in children means that careful monitoring is required during treatment.

Three case histories of nursing infants suffering from different forms of intestinal problems, who underwent special dietary therapy in order to solve situations that would be difficult to deal with using the special artificial milk varieties on the market, are presented. These children were administered a homemade food consisting ofParmigiano Reggiano cheese seasoned for at least 36 months, rice or maize custard and tapioca, sugar, maize oil. In the first case the diagnosis of "widespread nonspecific acute colitis" was made compatible with "antibiotic-associated colitis" and Clostridium difficile was isolated from the feces. The second case, under the suspicion of cow's milk allergy, was fed by soya and hydrolyzed milk with persitent disturbed alvus with greenish feces and mucus. The third case was represented by a nursing child with persistent diarrhoic alvus after an acute episode with subsequent intolerance to rice milk. After the introduction of the food based on Parmigiano Reggiano cheese, all cases showed a rapid and progressive improvement of symptoms and alvus characteristics and were discharged with increased weight. The Parmigiano Reggiano cheese shows a high concentration of easily absorbed amino acids and oligopeptides like a hydrolyzed proteic preparation. As regards the lipoid component the medium and short chain fatty acids are directly absorbed in the bowel and immediately usable as a significant source of energy. Finally, another relevant characteristic of Parmigiano Reggiano cheese is the complete absence of lactose. The use of Parmigiano Reggiano cheese as a dietary therapy is appropriate not only for its high nutritional value, but also for its characteristics as a functional food that produces beneficial effects on health with regards to the gastrointestinal tract and the inflammatory problems resulting from alimentary intolerance, post-therapeutic antibiotic dismicrobism, or post-infective conditions. Moreover, its efficay on these pathologic conditions is further improved by the prebiotic and probiotic effects resulting from the oligosaccharides and the bacterial flora of this natural food product, only derived from the nature and the work of skilled artisans closely tied to tradition.

The use of a short-stay observation unit (OBI) in a pediatric department has reduced the number of admissions. Significant cost savings and a better care for children and their families have been also achieved. During the year 2003 in our department 1759 children received OBI. 226 (12.8%) were then admitted. 1553 (87.2%) were discharged after a nine-hour mean stay. Descriptive statistics are used to outline the sample of patients and used treatments.
