Article Synopsis
  • The study aims to analyze the causes and management of acute ataxia (AA) in children and to find clinical signs indicating serious neurological issues.
  • A retrospective review was conducted on 509 pediatric patients seen for AA in emergency departments over eight years, revealing acute postinfectious cerebellar ataxia as the most common cause.
  • Key risk factors for serious neurological conditions included meningeal and focal neurological signs, hyporeflexia, and longer duration of symptoms, while a history of varicella-zoster virus infection reduced the risk.

Background: Acute ocular motility disorders (OMDs) in children admitted to Emergency Department (ED) represents a not so rare condition with a wide spectrum of different etiologies. The emergency physician must be skilled in rapidly identifying patients with potentially life threatening (LT) forms, requiring further diagnostic procedures. The aim of the study was to assess characteristics of children with acute Ocular Motility Disorders (OMDs), and to identify "red flags" for recognition of underlying life-threatening (LT) conditions.

Unlabelled: A sharp uptrend in emergency department (ED) visits for injuries associated with inflatable bouncers (IBs) has been observed recently. The aim of this study is to describe the epidemiology and features of injuries resulting from the use of IBs at an Italian pediatric ED. We collected data of 521 children from GIPSE (regional software for management of admission at ED) in the period of 2002-2013.

Objective: To evaluate the effectiveness of seasonal influenza vaccine in preventing Emergency Department (ED) visits and hospitalisations for influenza like illness (ILI) in children.

Methods: We conducted a test negative case-control study during the 2011-2012 and 2012-2013 influenza seasons. Eleven paediatric hospital/wards in seven Italian regions participated in the study.

Background: We report a case of rivastigmine poisoning resulting in a full cholinergic syndrome with nicotinic, muscarinic, and central effects requiring supportive or intensive care in a pediatric patient.

Case Report: A 3-year-old girl was admitted to the Emergency Department suspected of having ingested one or two pills of rivastigmine. The child was hyporeactive, with symptoms of altered mental status, sialorrhea, sweating, and diarrhea.

Objective: Stevens-Johnson Syndrome (SJS) is one of the most severe muco-cutaneous diseases and its occurrence is often attributed to drug use. The aim of the present study is to quantify the risk of SJS in association with drug and vaccine use in children.

Methods: A multicenter surveillance of children hospitalized through the emergency departments for acute conditions of interest is currently ongoing in Italy.

Background And Objectives: Prednisone and calcineurin inhibitors are the mainstay therapy of idiopathic nephrotic syndrome (INS) in children. However, drug dependence and toxicity associated with protracted use are common. Case series suggest that the anti-CD20 monoclonal antibody rituximab (RTX) may maintain disease remission.

Ribosomal S6 kinase 2 (S6K2) acts downstream of the mammalian target of rapamycin (mTOR). Here, we show that some S6K2 localize at the centrosome throughout the cell cycle. S6K2 is found in the pericentriolar area of the centrosome.

In mammalian cells, DNA replication takes place in functional subnuclear compartments, called replication factories, where replicative factors accumulate. The distribution pattern of replication factories is diagnostic of the different moments (early, mid, and late) of the S phase. This dynamic organization is affected by different agents that induce cell cycle checkpoint activation via DNA damage or stalling of replication forks.

We have determined the early effects of camptothecin and alpha-amanitin on genomic DNA-binding sites of RNA polymerase II (RNAPII), TATA-binding protein (TBP), DNA topoisomerase I (Top1), and histone components in human transcribed loci by chromatin-immunoprecipitation (ChIP). The two agents caused notably different alterations in active chromatin. Camptothecin induced a specific reduction of RNAPII density at promoter pause sites and histone modifications suggesting an increased chromatin accessibility.

In skeletal muscle differentiation, the retinoblastoma protein (pRb) is absolutely necessary to establish definitive mitotic arrest. It is widely assumed that pRb is equally essential to sustain the postmitotic state, but this contention has never been tested. Here, we show that terminal proliferation arrest is maintained in skeletal muscle cells by a pRb-independent mechanism.

In eukaryotes, initiation of DNA replication requires the activity of the origin recognition complex (ORC). The largest subunit of this complex, Orc1p, has a critical role in this activity. Here we have studied the subnuclear distribution of the overexpressed human Orc1p during the cell cycle.

We have described previously that, during S-phase, human DNA ligase I is phosphorylated on Ser66, a casein kinase II site. Here we investigate the phosphorylation status of DNA ligase I during the cell cycle by gel shift analysis and electrospray mass spectrometry. We show that three residues (Ser51, Ser76, and Ser91), which are part of cyclin-dependent kinase sites, are phosphorylated in a cell cycle-dependent manner.

Background And Objectives: Giannina Gaslini Children's Hospital (GGCH) is a tertiary care hospital with an average of 100 new cancer diagnoses made each year. In April 2000, following preliminary analysis of the potential benefits, and the results of a questionnaire filled in by the parents attending the out-patient clinic, a Home Care (HC) program was started.

Design And Methods: Children in stable, non-critical, clinical conditions requiring i.
