Life history of the talitrid amphipod Macarorchestia remyi (Schellenberg, 1950) on a Tyrrhenian sandy beach, Italy
No full textIn this study, we analysed the life cycle and some aspects of the reproductive biology of the talitrid amphipod Macarorchestia remyi (Schellenberg, 1950) on a sandy beach in central Italy (Tyrrhenian Sea). The species is strongly associated with rotting wood carried by the sea. The animals were sampled once a month by hand over 1 year (May 2006-April 2007) and a total of 3,484 individuals were collected. Results showed the occurrence of intersexes in addition to males and females (n = 268) and a sex ratio always in favour of females. Breeding peaked twice during the year and the number of eggs in the ventral brood chamber ranged from 3 to 19. Linear regression analysis showed a positive correlation between total length of ovigerous females and the number of eggs they carried. The mean length of both mature males and mature females was 6 mm, while the maximum length was 13 mm. The presence of two cohorts during the year was also identified. Our results suggest that, despite the ephemeral habitats where the species lives, the population is stable over time and its life cycle does not differ in relation to other talitrid species that live on beaches

Hepatic sonography in patients with hereditary hemorrhagic telangiectasia hospitalized for epistaxis
No full textHereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by the presence of telangiectasias and arteriovenous malformations in various organs and organ systems, including the liver. The most frequent clinical manifestation of HHT is epistaxis. In 2010 (January-December inclusive) 51 patients with HHT were admitted to the ENT ward of our hospital for epistaxis, and in accordance with routine protocols, all 51 underwent abdominal ultrasonography in our department to detect hepatovascular lesions. They included 27 males (53%) and 24 (47%) females ranging in age from 11 to 86 years (mean 48.5 years). The sample was selected in an arbitrary manner to take maximum advantage of the hospital stay and monitor patients from regions other than our own. Retrospective analysis of the findings from these sonographic examinations revealed hepatic HHT in 27 (53%) of the 51 patients. Nineteen (70%) of these (age range 40-86 years, mean 63) had vascular malformations of various dimensions but no portal hypertension; the other eight (30%) (age range 39-81 years, mean 60) had vascular malformations plus portal hypertension. Our retrospective analysis indicates that a significant number of patients can have unrecognized hepatic involvement; that the appearance of hepatic lesions can be fairly unpredictable, even when the HHT has been diagnosed for years and the patients are already symptomatic; and that the hepatic lesions are frequently progressive. Therefore, regular sonographic follow-up is advisable for patients with HHT. The limitations of this study are related to the small number of patients examined and to the fact that all of them were symptomatic. Further study is therefore needed (especially in asymptomatic patients) to define the indications for hepatic sonography and the optimum examination schedule
