  • Aplastic Crisis Caused by Parvovirus B19 in an Adult Patient with Sickle-Cell Disease
    Revista da Sociedade Brasileira de Medicina Tropical RELATO DE CASO 33(5):477-481, set-out, 2000. Aplastic crisis caused by parvovirus B19 in an adult patient with sickle-cell disease Crise aplástica por parvovírus B19 em um paciente adulto com doença falciforme Sérgio Setúbal1, Adelmo H.D. Gabriel2, Jussara P. Nascimento3 e Solange A. Oliveira1 Abstract We describe a case of aplastic crisis caused by parvovirus B19 in an adult sickle-cell patient presenting with paleness, tiredness, fainting and dyspnea. The absence of reticulocytes lead to the diagnosis. Anti-B19 IgM and IgG were detected. Reticulocytopenia in patients with hereditary hemolytic anemia suggests B19 infection.

Several viruses have Virome been tentatively associated to such syndrome. Here, in order to examine potential associations between enteric Broiler chickens viruses and MAS, the faecal viromes of 70 stool samples collected from diseased (n = 35) and healthy (n = 35) High-throughput sequencing chickens from seven flocks were characterized and compared. Following high-throughput sequencing, a total of 8,347,319 paired end reads, with an average of 231 nt, were generated. Through analysis of de novo assembled contigs, 144 contigs > 1000 nt were identified with hits to eukaryotic viral sequences, as determined by GenBank database.

Ilaria Conti Supervisor: Prof. Giorgio Gallinella PhD course: Scienze Biotecnologiche e Farmaceutiche, XXXI ciclo Thesis: “Human Parvovirus B19: from the development of a reverse genetics system to antiviral strategies” Human Parvovirus B19 (B19V) is a human pathogenic virus which belongs to the Parvoviridae family. It is worldwide distributed and is responsible of various clinical manifestations in human, although neither an antiviral therapy nor a vaccine are available. The virus is not well adapted to grow in cellular cultures and this causes difficulties for its propagation, maintaining and characterization. B19V has a narrow tropism for the erythroid progenitor cells of human bone marrow and very few cellular systems can support the viral replication (such as, UT7/EpoS1 cells which is a megakaryoblastoid cell line). In this research, a reverse genetic approach was developed to allow the generation of mature and infectious viral particles from an established consensus sequence. Synthetic clones that differ for the length and isomerism of their terminal regions (ITRs) were constructed. After their transfection in UT7/EpoS1 cells, the obtained viral particles were used to infect EPCs (erythroid progenitor cells) in serial passages, in order to evaluate the capability for each clone to generate a new viral stock and to propagate it.

Here, two highly divergent BOVs (tentatively named as Himalayan marmot BOV, HMBOV1 and HMBOV2) were identified in the livers and feces of wild Himalayan marmots in China, by viral metagenomic analysis. Five of 300 liver samples from Himalayan marmots were positive for HMBOV1 and five of 99 fecal samples from these animals for HMBOV2. Their nearly complete genome sequences are 4,672 and 4,887 nucleotides long, respectively, with a standard genomic organization and containing protein-coding motifs typical for BOVs. Based on their NS1, NP1, and VP1, HMBOV1 and HMBOV2 are most closely related to porcine BOV SX/1-2 (approximately 77.0%/50.0%, 50.0%/53.0%, and 79.0%/54.0% amino acid identity, respectively).

Many reports covered the commonest paraviral exanthems, namely pityriasis rosea and Gianotti-Crosti syndrome. We reviewed here the managements of the less common paraviral exanthems in children. For asymmetrical periflexural exanthem/unilateral laterothoracic exanthem treatments should be tailored to the stages of the rash. For children with papular purpuric gloves and socks syndrome, important differential diagnoses such as Kawasaki disease should be ex- cluded. Where this exanthem is related to parvovirus B19 infection, the risk of aplastic reticulocytopenia should be monitored for. Clinicians should also be aware of ongoing in- fectivity of parvovirus B19 infection upon rash eruption, and possible exposure to pregnant women. For children with eruptive pseudoangiomatosis, important differential diagnoses should be excluded. For eruptive hypomelanosis, the prime concern is that virological investiga- tions should be contemplated where available, as there exists only clinical and epidemiolo- gical evidence for this novel exanthem being caused by an infectious microbe. Key words Acyclovir, Gianotti-Crosti syndrome, human herpesvirus-7, human herpesvirus-6, papu- lar acrodermatitis, pityriasis rosea.

Communication specialists at EMA use these descriptions for materials prepared for the public. In our documents, we often adjust the description wordings to fit the context so that the writing flows smoothly without distorting the meaning. Since the main purpose of these descriptions is to serve our own writing needs, some also include alternative or optional wording to use as needed; we use ‘<>’ for this purpose. Our list concentrates on side effects and similar terms in summaries of product characteristics and public assessments of medicines but omits terms that are used only rarely. It does not include descriptions of most disease states or those that relate to specialties such as regulation, statistics and complementary medicine or, indeed, broader fields of medicine such as anatomy, microbiology, pathology and physiology.

This means that 2018 marked the 41st edition of the competition. This year, 39 universities registered for the competition and National Rounds were held in eight countries to determine which teams would proceed to the International Rounds in The Hague. For teams without a National Round it was possible to participate in the International Friendly Rounds, organised by Vaccaro Law Bureau at the European University Institute in Florence. The main objective of the Telders Competition is to stimulate students’ interest and knowledge of international law. It is an exceptional opportunity for the participants in a variety of ways. In taking part, students are educated in legal practice, and such important principles as the rule of law and fair play. The Competition provides an excellent platform for experiencing a close-to-reality court setting. It offers an opportunity for students to enhance their networks and promotes international cooperation and understanding.
