Congenital diaphragmatic hernia : a European population-based study of epidemiology, prenatal diagnosis and mortality

Aim: To study the epidemiology and the impact of prenatal diagnosis on mortality and morbidity in infants with isolated congenital diaphragmatic hernia (CDH). Methods: Cases were identified in eight population-based registries of congenital malformations (Eurocat) in Europe. Results: A total of 183 live births were included in the study. Sixty per cent died and 67% of all deaths were during the first day of life. CDH was diagnosed prenatally in 39% of cases. Both mortality and morbidity were significantly higher for infants diagnosed prenatally compared to those diagnosed postnatally. The Apgar score was a very sensitive indicator for survival. Gestational age at birth was significantly lower for infants diagnosed prenatally compared to those diagnosed postnatally (37.6 weeks vs. 38.8 weeks, p < 0.01). At the end of follow-up, half of the survivors were leading a normal life. The most frequently reported health problems were respiratory and gastrointestinal symptoms. Conclusions: In this population-based study, mortality for infants with CDH was high (60%) and early prenatal diagnosis was a risk factor for survival. Intervention at the time of birth seems too late for the majority of newborn infants with CDH.

Percorsi dell'emigrazione italiana in Svizzera tra fonti orali e scritture di gente comune (1946-1974)

Sintesi II presente lavoro di ricerca, maturato nel quadro di un dottorato in storia contemporanea, propone una ricostruzione dei percorsi materiali e dei percorsi culturali degli emigrati italiani in Svizzera tra la tìne della Seconda guerra mondiale e i primi anni Settanta. Le principali fonti di prima mano adoperate nella ricerca consistono in tre diversi generi di narrazioni autobiogratìche: le fonti orali (cento interviste complessive raccolte e analizzate); le scritture epistolari (tre fondi per un totale di circa duecento lettere); le scritture scolastiche di adolescenti e giovani emigrati italiani, iscritti, tra la fine degli anni Sessanta e i primi anni Settanta, ad una scuola privata del Canton Zurigo (circa seicento temi validi come prova di lingua italiana per il conseguimento della licenza media tra il 1973 e il 1974). Le fonti soggettive raccolte hanno permesso di tracciare i profili di numerosi di percorsi migratori vissuti da queste persone, lavorando, in primo luogo, sulla loro dimensione materiale, ovvero sulle tappe íìsiche, dal viaggio, alla ricerca del posto di lavoro e dell'alloggio, alla formazione di una famiglia, agli strumenti utilizzati per mantenersi in contatto con il proprio paese d'origine. Si sono poi inquadrate alcune delle possibili evoluzioni ideologiche e culturali, nei termini consentiti dallo studio della memoria e delle rappresentazioni di sé, offerte dagli emigrati stessi. In sintesi, quindi, il lavoro propone una ricostruzione di un frammento di storia dell'emigrazione italiana, con tutte le specitìcità legate a un paese di accoglienza, la Svizzera, e a un periodo storico, il Secondo dopoguerra. Alcuni dei caratteri principali dei percorsi materiali sono senz'altro legati alle peculiarità della legislazione svizzera, con la detìnizione di "straniero" che dava, le condizioni di vita che rendeva praticabili e possibili, i passaggi di tempo che imponeva per avere una permesso a tempo indeterminato, per raggiungere una certa stabilità, per ricomporre il proprio nucleo familiare. Anche alcuni fenomeni culturali erano legati a queste dimensioni specitïche, per cui non hanno riscontro, negli stessi termini, in altri contesti e in altri periodi. Accanto alle peculiarità e alle differenze che questa storia ha rispetto ad altre storie di emigrazione legate ad altri paesi e ad altri contesti, dal lavoro emergono processi e fenomeni di interesse più generale, qualora ci si interessi di fenomeni migratori, di conflitti, di inclusione e di esclusione di gruppi umani differenti. Alcune delle problematiche che si sono poste nella storia in analisi -per esempio quelle relative alla scolarizzazione dei minori, al rapporto tra diritto di residenza e obbligo di impiego, alla presenza di clandestini e al loro rapporto con associazioni o gruppi di assistenza legali o illegali -sono senza dubbio utili riferimenti per chi oggi voglia ragionare su problematiche analoghe poste in diversi contesti.

Pyoderma gangrenosum after minor trauma in a pregnant woman, mistaken for necrotizing fasciitis: report of a case and literature review.

Abstract Background: Pyoderma gangrenosum is an ulcerative, non-infectious skin disorder. However, it can be mistaken as necrotizing fasciitis, a life-threatening infective condition. We describe here a case of pyoderma gangrenosum after minor trauma treated as necrotizing fasciitis. METHODS: Case report and literature review. CASE REPORT: A 27-year-old pregnant nurse had a pretibial wound after a fall on a rough surface. When erythema developed and no response to empirical antibiotic therapy was observed, multiple debridements were performed. Paradoxically, her condition became worse. The diagnosis of pyoderma gangrenosum was suspected. Treatment with corticosteroids was started and this was successful. CONCLUSION: Pyoderma gangrenosum can mimic infectious necrotizing fasciitis. Differentiating these two conditions is important because mistreatment of pyoderma can lead to disfigurement.

Daniel Sudermann als Romanleser. Spuren weltlicher Literatur des Mittelalters in einer geistlichen Büchersammlung der Frühen Neuzeit

Der Beitrag untersucht Handschriften mit weltlichen Texten, die sich aus der geistlichen Büchersammlung des Spiritualisten und Schwenckfeld-Anhängers Daniel Sudermann (1550-ca. 1631) erhalten haben oder für diese Sammlung erschlossen werden können. Anhand von Lektürenotizen Sudermanns in seinen Handschriften sowie einem kommentierten Bücherverzeichnis, aber auch anhand von inhaltlichen Bezügen der Texte untereinander werden mögliche Anziehungspunkte und konkrete Leseinteressen rekonstruiert, die Sudermann mit der Profanliteratur des Mittelalters verbunden haben könnte. Dabei erweist sich, daß Sudermann die weltliche Romanliteratur des Mittelalters entgegen der bisherigen Einschätzung durchaus gewürdigt hat. Allerdings las er sie nicht mit der Faszination an der Fiktion, die ihren mittelalterlichen Lesern zuzutrauen ist, sondern rezipierte sie im Sinne historischer Quellen, wobei zwei Interessenschwerpunkte zu identifizieren sind: Sudermann beschäftigte sich mit der fabulösen Frühgeschichte des Christentums in Indien, an die eine große Mehrzahl der aus seinem Besitz bekannten weltlichen Texte direkt oder indirekt anschließt. Daneben galt seine Aufmerksamkeit adelsgenealogischen Informationen, die er der mittelalterlichen Romanliteratur entnehmen zu können glaubte. Den Aufsatz begleitet ein Faksimileabdruck von Sudermanns Autograph des kommentierten Bücherverzeichnisses.

Polymorphisms in Toll-like receptor 4 (TLR4) are associated with protection against leprosy.

Accumulating evidence suggests that polymorphisms in Toll-like receptors (TLRs) influence the pathogenesis of mycobacterial infections, including leprosy, a disease whose manifestations depend on host immune responses. Polymorphisms in TLR2 are associated with an increased risk of reversal reaction, but not susceptibility to leprosy itself. We examined whether polymorphisms in TLR4 are associated with susceptibility to leprosy in a cohort of 441 Ethiopian leprosy patients and 197 healthy controls. We found that two single nucleotide polymorphisms (SNPs) in TLR4 (896G>A [D299G] and 1196C>T [T399I]) were associated with a protective effect against the disease. The 896GG, GA and AA genotypes were found in 91.7, 7.8 and 0.5% of leprosy cases versus 79.9, 19.1 and 1.0% of controls, respectively (odds ratio [OR] = 0.34, 95% confidence interval [CI] 0.20-0.57, P < 0.001, additive model). Similarly, the 1196CC, CT and TT genotypes were found in 98.1, 1.9 and 0% of leprosy cases versus 91.8, 7.7 and 0.5% of controls, respectively (OR = 0.16, 95% CI 0.06--.40, P < 0.001, dominant model). We found that Mycobacterium leprae stimulation of monocytes partially inhibited their subsequent response to lipopolysaccharide (LPS) stimulation. Our data suggest that TLR4 polymorphisms are associated with susceptibility to leprosy and that this effect may be mediated at the cellular level by the modulation of TLR4 signalling by M. leprae.

Consciência nacional, democratização e conflito político: semelhanças e diferenças entre Guiné-Bissau e Moçambique

Este trabalho debate a consciência nacional, a democratização e o conflito político vivenciados pela sociedade e pelo Estado guineense e moçambicano durante o processo de construção do Estado Nacional, bem como suas implicações nas recentes experiências de institucionalização da democracia minimalista-liberal que resultou num acentuado processo de diferenciação e pluralização de identidades e de atores sociais e políticos. Queremos entender, especificamente, o conflito entre a identidade nacional e as identidades étnicas surgido das tentativas do primeiro em controlar politicamente estas últimas durante a construção do nacionalismo. Não obstante a essa tentativa da homogeneização das diferenças étnicas e regionais, o discurso proto-nacionalista que defendia, pelo menos em termos da retórica, a bandeira da unidade nacional, mostrou-se insuficiente com a proliferação e a reconfiguração identitária dos grupos étnicos que as ideologias nacionalista-revolucionárias tentaram abafar ou reduzir a meros instrumentos ideológicos da luta de classes dentro do Estado burocrático-autoritário.

Internalization and homologous desensitization of the GLP-1 receptor depend on phosphorylation of the receptor carboxyl tail at the same three sites.

Homologous desensitization and internalization of the GLP-1 receptor correlate with phosphorylation of the receptor in a 33-amino acid segment of the cytoplasmic tail. Here, we identify the sites of phosphorylation as being three serine doublets located at positions 441/442, 444/445, and 451/452. The role of phosphorylation on homologous desensitization was assessed after stable expression in fibroblasts of the wild type or of mutant receptors in which phosphorylation sites were changed in various combinations to alanines. We showed that desensitization, as measured by a decrease in the maximal production of cAMP after a first exposure of the cells to GLP-1, was strictly dependent on phosphorylation. Furthermore, the number of phosphorylation sites correlated with the extent of desensitization with no, intermediate, or maximal desensitization observed in the presence of one, two, or three phosphorylation sites, respectively. Internalization of the receptor-ligand complex was assessed by measuring the rate of internalization of bound [125I]GLP-1 or the redistribution of the receptor to an endosomal compartment after agonist binding. Our data demonstrate that internalization was prevented in the absence of receptor phosphorylation and that intermediate rates of endocytosis were obtained with receptors containing one or two phosphorylation sites. Thus, homologous desensitization and internalization require phosphorylation of the receptor at the same three sites. However, the differential quantitative impairment of these two processes in the single and double mutants suggests different molecular mechanisms controlling desensitization and internalization.

Evaluating Spanish pension expenditure under alternativa reform scenario

In this paper we evaluate the quantitative impact that a number ofalternative reform scenarios may have on the total expenditure for publicpensions in Spain. Our quantitative findings can be summarized in twosentences. For all the reforms considered, the financial impact of themechanical effect (change in benefits) is order of magnitudes larger thanthe behavioral impact or change in behavior. For the two Spanish reforms,we find once again that their effect on the outstanding liability of theSpanish Social Security System is essentially negligible: neither themechanical nor the behavioral effects amount to much for the 1997 reform,and amount to very little for the 2002 amendment.
