Ocular neovascularizations are responsible for irreversible loss of vision in various diseases, including age-related macular degeneration. Treatments have changed greatly, and photodynamic therapy with verteporfin has come into common use. However, the visual prognosis remains poor. The recent approval of new antiangiogenic molecules such as ranibizumab and pegaptanib should allow for new therapeutical possibilities. The unapproved ophthalmological use of bevacizumab requires further studies. This paper updates what is known about old and new neovascularization treatments: their mechanism of action, their efficacy, and their toxicity. It reviews the principal clinical studies, and concludes with the recognized recommendations. For the first time, ophthalmologists can hope not only to stabilize loss of vision, but also to improve visual acuity. Complementary treatments can now be tested in associations, concomitantly or not, with the hope of improving visual results.

Les travaux qui se sont intéressés à l'hypothèse des avantages et désavantages cumulatifs (ADC) dans la perspective du parcours de vie montrent comment, au sein d'une même cohorte, des différences initiales pour une caractéristique déterminée (sexe, statut social, santé) contribuent à structurer des trajectoires de vie différenciées. La plupart de ces études se concentrent sur l'empan de vie sans mesurer l'effet que des transitions particulières jouent dans ce processus. Dans cet article nous nous centrons sur la transition à la parentalité pour montrer que le type d'insertion professionnelle des partenaires avant cette transition explique la différenciation subséquente de leurs trajectoires professionnelles. Abstract Life course studies focusing on the cumulated advantages and disadvantages (CAD) hypothesis indicate that initial differences in a specific characteristic (sex, social status, or health) have an impact on intracohort differentiation. Most of these studies consider an entire life course and do not focus on specific transitions as a key moment for differentiation. In this article, the researchers focus on the transition to parenthood, showing that variations in occupational participation of both partners before the birth of a first child explain how professional trajectories differentiate after the birth of the child. Zusammenfassung Die Arbeiten, die sich für die Hypothese der kumulierten Vor- und Nachteile in einer Lebenslaufperspektive interessiert haben, zeigen, wie anfängliche Unterschiede bezüglich bestimmter Charakteristiken (Geschlecht, sozialer Status, Gesundheit) innerhalb einer Kohorte zur Strukturierung unterschiedlicher Lebensläufe beitragen. Die meisten dieser Studien konzentrieren sich auf den Gesamtlebenslauf, ohne die Effekte spezifischer biographischer Übergänge zu messen. In diesem Artikel beschränken wir uns auf den biographischen Übergang zur Elternschaft. Wir zeigen auf, wie die Erwerbssituation der Partner vor diesem Übergang die nachfolgende Differenzierung ihrer Berufsverläufe beeinflusst.

La maladie liée aux immunoglobulines de type G4 (ML-IgG4) est reconnue depuis le début des années 2000 comme une entité regroupant un ensemble de maladies inflammatoires à caractéristiques histopathologiques communes. Pouvant atteindre quasiment tous les organes et tissus, elle se manifeste le plus souvent de manière subaiguë chez des hommes de plus de 50 ans, sous forme de masse ou d'agrandissement diffus des organes atteints. L'aspect histopathologique est celui d'une infiltration lymphoplasmocytaire à prédominance de plasmocytes IgG4 positifs et d'une fibrose progressive. Ses caractéristiques cliniques et radiologiques peuvent rendre difficile la distinction avec un processus tumoral. La maladie répond bien à un traitement systémique de glucocorticoïdes, avec toutefois un haut taux de récidives après l'arrêt du traitement. Immunoglobulin G4 related disease (IgG4-RD) has been recognized since early 2000s as an entity comprising a set of inflammatory diseases with common histopathological features. The disease may affect almost all organs and tissues, and often occurs in a subacute fashion in males over 50 years as a mass or diffuse enlargement of affected organs. The histopathological appearance is characterized by a lymphoplasmacytic infiltration with predominantly IgG4-positive plasma cells and progressive fibrosis. Its clinical and radiological features can make the distinction with a malignancy difficult. The disease responds well to systemic glucocorticoids however with a high rate of recurrence after treatment discontinuation.
