Salso-bromo-iodine thermal water: a nonpharmacological alternative treatment for postnasal drip-related cough in children with upper respiratory trac…
2018
Postnasal drip (PND)-related cough is a very common symptom in patients with upper respiratory tract infections (URTis). At present, there is not a standard treatment for postnasal drip and postnasal drip-related cough. The aim of this pilot study was to evaluate the efficacy of a specific salso-bromoiodine thermal water containing hyaluronic acid and grapefruit seed extract (SBI-H-GSE) comparing it with a normal saline solution in children with URTis who refer PND-related symptoms. The study was randomized, single-blind, and controlled. Study group (75 children) was treated with SBI-HGSE and control group (65 children) was treated with a normal saline solution; both compounds were administ…
Effective infection, apoptotic cell killing and gene transfer of human hepatoma cells but not primary hepatocytes by parvovirus H1 and derived vector…
2001
Autonomous parvoviruses preferentially replicate in and kill in vitro–transformed cells and reduce the incidence of spontaneous and implanted tumors in animals. Because of these natural oncotropic and oncolytic properties, parvoviruses deserve to be considered as potential antitumor vectors. Here, we assessed whether parvovirus H1 is able to kill human hepatoma cells by induction of apoptosis but spares primary human liver cells, and whether the former cells can efficiently be transduced by H1 virus–based vectors. Cell death, infectivity, and transgene transduction were investigated in Hep3B, HepG2, and Huh7 cells and in primary human hepatocytes with natural and recombinant H1 virus. All h…
Novel recombinant GII.P16_GII.13 and GII.P16_GII.3 norovirus strains in Italy.
2014
Novel norovirus strains are continuously emerging worldwide. Molecular investigation and phylogenetic analysis identified GII.P16 recombinant noroviruses from the stools of four Italian children with gastroenteritis. The capsid gene was characterized as either GII.13 or GII.3. The GII.P16_GII.13 Italian strains were closely related to German strains involved in a large outbreak in the second half of 2012 and the Italian strains are the first recorded occurrence of GII.P16_GII.13 in Europe.
Geographical distribution and oncogenic risk association of human papillomavirus type 58 E6 and E7 sequence variations.
2013
Human papillomavirus (HPV) 58 accounts for a notable proportion of cervical cancers in East Asia and parts of Latin America, but it is uncommon elsewhere. The reason for such ethnogeographical predilection is unknown. In our study, nucleotide sequences of E6 and E7 genes of 401 HPV58 isolates collected from 15 countries/cities across four continents were examined. Phylogenetic relationship, geographical distribution and risk association of nucleotide sequence variations were analyzed. We found that the E6 genes of HPV58 variants were more conserved than E7. Thus, E6 is a more appropriate target for type-specific detection, whereas E7 is more appropriate for strain differentiation. The frequ…
No association between human herpesvirus type 8 infection and multiple myeloma.

A survey of seroprevalence of human papillomavirus types 16, 18 and 33 among children.
1999
The importance and natural history of HPV infections in childhood is incompletely understood. We performed a survey for presence of serum antibodies to HPV capsids among 1031 children aged 0 to 13 years, resident in Stockholm, Sweden. The HPV seroprevalence among these children was 3.0% for HPV16, 0.6% for HPV18 and 2.7% for HPV33. By comparison, among simultaneously analyzed positive control panels comprising women with CIN or healthy women with type-specific cervical HPV DNA, seroprevalence of HPV 16, 18 and 33 was 69%, 58% and 63% respectively. The results suggest that HPV infection in childhood is not common.
Heat Shock Protein Vaccines Against Cancer
1993
Vaccination of mice with heat shock proteins (HSPs) derived from a tumor makes the mice resistant to the tumor from which the HSP was obtained. This phenomenon has been demonstrated with three HSPs--gp96, hsp90, and hsp70. Vaccination with HSPs also elicits antigen-specific cytotoxic T lymphocytes (CTLs). The specific immunogenicity of HSPs derives apparently, not from the HSPs per se, but from the peptides bound to them. These observations provide the basis for a new generation of vaccines against cancer. The HSP-based cancer vaccines circumvent two of the most intractable hurdles to cancer immunotherapy. One of them is the possibility that human cancers, like cancers of experimental anima…
Being candid about Candida airway colonization and clinical outcomes: What can we really learn from unadjusted associations?

Repercusión de los factores clínicos y microbiológicos en la selección de la especie causal de candidemia en el paciente crítico adulto en un hospita…
2017
ANTECEDENTES: Las micosis invasoras son infecciones emergentes asociadas a elevada morbi-mortalidad en pacientes críticos, siendo la candidiasis invasora (con o sin candidemia asociada) la más frecuente en todas las latitudes. Los pacientes ingresados en Unidades de Críticos (UC), debido a sus enfermedades de base y al desarrollo de técnicas diagnósticas y terapéuticas cada día más agresivas, tienen un elevado riesgo de presentar candidiasis invasora. Aunque Candida albicans es el agente etiológico de candidemia más habitual en todos los hospitales, en las últimas décadas se ha observado un aumento en la incidencia de especies no albicans. Este cambio en la etiología de la candidemia tambié…
Carbapenem-Susceptible OXA-23-Producing Proteus mirabilis in the French Community
2019
International audience; Nineteen Proteus mirabilis isolates producing the carbapenemase OXA-23 were recovered over a 2-year period in 19 French hospitalized patients, of whom 12 had community onset infections. The isolates exhibited a slightly reduced susceptibility to carbapenems. Whole-genome analysis revealed that all 19 isolates formed a cluster compared to 149 other P. mirabilis isolates. Because of its susceptibility to carbapenems, this clone may be misidentified as a penicillinase producer while it constitutes a reservoir of the OXA-23-encoding gene in the community.
