Espécies novas do Herbário do Dr. Adolpho Lutz: Melastomataceae Tibouchina Lutzii Brade n.sp

A posição desta espécie é após Tibouchina floribunda Cogn. No hábito assemelha-se a Tibouchina Schwackei Cogn. mas distingue-se bem desta pelo revestimento diferente e a côr alva da página inferior da folha.

Bromeliaceae do Herbário do Dr. Adolpho Lutz: Encholirium Lutzii L. B. Smith n. sp

Encholirium Lutzii is distinguished from the majority of species by its branched inflorescence. Only E. horridum L. B. Smith and rarely E. spectabile Martius exhibit this character, but have much larger flowers than E. Lutzii and stout floral axes. Also the wing of the seed in E. horridum is very long-caudate. We feel that it is particularly appropriate to dedicate this new species to Dr. Adolpho Lutz because of his great discoveries in the biological relationships of the Bromeliaceae.

Cultured human fetal astrocytes can be induced by interferon-gamma to express HLA-DR.

Interferon-gamma (IFN-gamma) modulates the expression of Class II major histocompatibility antigens (MHC), thus providing a potential regulatory mechanism for local immune reactivity in the context of MHC-restricted antigen presentation. Within the central nervous system (CNS), the expression of MHC Class II antigens has been demonstrated on human reactive astrocytes and glioma cells. In order to investigate the modulation of HLA-DR on normal astrocytes, two cell lines were grown from a 20-week-old fetal brain. In situ none of the fetal brain cells expressed HLA-DR as determined by immunohistology on frozen tissue sections. The two cell lines, FB I and FB II, expressed GFAP indicating their astrocytic origin. FB I was HLA-DR negative at the first tissue culture passages, but could be induced to express HLA-DR when treated with 500 U/ml IFN-gamma. FB II was spontaneously HLA-DR positive in the early passages, lost the expression of this antigen after 11 passages and could also be induced to express HLA-DR by IFN-gamma. The induction of HLA-DR expression was demonstrated both by a binding RIA and by immunoprecipitation using a monoclonal antibody (MAB) directed against a monomorphic determinant of HLA-DR. The HLA-DR alloantigens were determined on FB II cells after IFN-gamma treatment, by immunofluorescence and by cytotoxicity assays, and were shown to be DR4, DR6, Drw52, DRw53 and DQwl. These results show that human fetal astrocytes can be induced to express HLA-DR by IFN-gamma in vitro and support the concept that astrocytes may function as antigen-presenting cells.

Síndrome de Sweet: estudio retrospectivo de 24 pacientes en el área del Hospital Universitario Dr. Peset de Valencia

El Síndrome de Sweet (SS) es la más característica de todas las dermatosis neutrofílicas sobre todo por las entidades a las que se asocia, dada su finalidad pronóstica y terapeútica. Para definir el perfil de los pacientes diagnosticados de SS en nuestro departamento y evaluar las diferencias clínico-epidemiológicas entre subgrupos, hemos realizado un estudio retrospectivo desde 2001 a 2009, ambos inclusive, donde se han incluido veinticuatro pacientes (13 mujeres y 11 hombres) que han sido reagrupados en 4 categorías según la etiología: infecciosa, paraneoplásica, parainflamatoria e idiopática. Los resultados obtenidos se han comparado con estudios previos, encontrando algunas diferencias significativas.

Report to the Minister for Health and Children: Independent Examination related to the Medical Council and South-Eastern Health Board (Dr John Harding Price)

The Minister for Health and Children has requested that an independent review be carried out of the circumstances surrounding the employment of a UK based Consultant Psychiatrist, Dr John Harding-Price, to a locum psychiatrist position with the South Eastern Health Board (SEHB) while he was suspended by the General Medical Council (GMC) in the United Kingdom and consequently the subject of legal proceedings by the Medical Council in Ireland. The Consultant was continuously registered with the Medical Council since 1968. Download the document here

Estacionalidad de la tuberculosis en el área del Hospital Universitario Dr Peset de Valencia

La tuberculosi (TB) és una malaltia infecciosa. Diversos estudis han analitzat l'existència d'un patró estacional en la seva presentació amb resultats discordants. Ens vam proposar conèixer el patró estacional de diagnòstic de la malaltia en l'àrea del nostre hospital. Realitzem un estudi observacional prospectiu de tots els pacients, diagnosticats de TB durant el període 2002-2009 en el nostre Departament. Per a l'anàlisi estadística de les dades recollides s'ha utilitzat l'aplicació informàtica SPSS 15.0. amb un nivell de significació: p &0,05. En el nostre medi i clima, el diagnòstic de la tuberculosi pulmonar predomina durant els mesos càlids. Aquest predomini no s'ha relacionat amb les característiques socio-demogràfiques ni clíniques dels pacients.

Report of Dr Deirdre Madden on Post Mortem Practice and Procedures

This Report aims to set out the general facts in relation to paediatric post-mortem practice in Ireland from 1970 to 2000, the way in which information was communicated to parents of deceased children in relation to post-mortemexaminations, and how these practices might be improved upon for the future Read the Report
