The objectives of this study were to determine the incidence of enteric pathogens causing acute gastroenteritis (AGE) among hospitalized children in a large Italian hospital, to measure the incidence of coinfections, and to compare the clinical characteristics of those infected with one versus multiple agents. A prospective study was conducted from March(More)
Children with Down syndrome (DS) have increased susceptibility to infections and a high frequency of leukemia and autoimmune disorders, suggesting that immunodeficiency and immune dysfunction are integral parts of the syndrome. A reduction in B-cell numbers has been reported, associated with moderate immunodeficiency and normal immunoglobulin levels. Here,(More)
Although varicella has usually an uncomplicated course in early childhood, several neurological complications may occur. We conducted a study to review the type and the rate of varicella neurological complications in a case series of hospitalized immunologically healthy children over nearly a 8 year period. We also systematically reviewed data from the(More)
A 12 year old boy presented with an acute onset of anisocoria and blurred vision. Ocular motility was normal but his right pupil was dilated, round but sluggishly reactive to light. There was no history of trauma, eye drops' instillation, nebulised drugs or local ointments. His past medical history was negative.A third nerve palsy was considered but the(More)
BACKGROUND Immunodeficiency is an integral aspect of Down syndrome, as demonstrated by the increased susceptibility to infection of affected. Mortality is still higher than in general population, with respiratory infections among the major causes of death. As more people with Down syndrome are living today than ever before, it is indispensable to develop(More)
BACKGROUND We describe methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage at admission in patients admitted to a Department of Pediatrics. METHODS All patients received a nasal swab at admission. A questionnaire was administered and molecular genetics analyses were performed on all identified MRSA isolates. RESULTS We enrolled 785(More)
Four patients treated in one ward of a psychiatric clinic were admitted to our burn unit within 2 months due to severe burn injuries. The patients showed signs of a self-mutilation epidemic. All four patients were female and the mean age was 28 years. The psychiatric diagnosis was schizophrenia in all patients (ICD 10: F20.9). The ignition of flammable(More)
BACKGROUND Photo documentation (color slides) of abnormal optic nerve heads enable the clinician to accurately access or estimate the percentage of the optic nerve cupping to quantify the progression of glaucoma. The purpose of this study is to compare cupping estimations using digital images on a computer monitor to those using standard color slides. (More)
We evaluated a multiplex PCR assay, the Seeplex Diarrhoea ACE detection, that simultaneously detects 15 enteric pathogens, including Salmonella spp., Shigella spp., Vibrio spp., toxin B producer Clostridium difficile, Campylobacter spp., Clostridium perfringens, Yersinia enterocolitica, Aeromonas spp., Escherichia coli O157:H7, verocytotoxin-producing(More)
Around 65% of primary immunodeficiencies are antibody deficiencies. Functional tests are useful tools to study B-cell functions in vitro. However, no accepted guidelines for performing and evaluating functional tests have been issued yet. Here, we report our experience on the study of B-cell functions in infancy and throughout childhood. We show that(More)
