In the Mediterranean area, the species of the genus Helichrysum Mill. (Asteraceae) have very similar genetic traits despite they may show different morphological characteristics. A first genetic and morphological assessment on twelve populations of Helichrysum from Elba, Capraia and Giglio Islands, in the Tuscan Archipelago (Italy) was carried out. To determine their taxonomic identity, additional reference specimens belonging to the three Helichrysum species reported from the Tuscan Islands in the literature -H. italicum (Roth) G. Don subsp. italicum, H. litoreum Guss., and H. stoechas L.-, were also included in the assessments. Our results show that the Tuscan Archipelago populations have low levels of morphological and genetic variation. In particular, the variability was mainly observed at the intra-population level, as revealed by the coefficient of variation and AMOVA-Gst in the morphological and genetic analyses, respectively. Basing on our results, all examined populations from the Tuscan Archipelago seem fit in H. italicum subsp. italicum. However, we detect and discuss the existence of some intermediate specimens, mainly with H. litoreum, reflecting the complexity of Helichrysum's taxonomy and highlighting the need for additional studies to fully understand the various patterns and the underlying evolutionary events that originated them.

A 45-year-old woman affected by MEN-1 syndrome with a history of bilateral nephrolithiasis due to parathyroid adenoma (primary hyperparathyroidism) and celiac disease presented to the nephrologist for recurrent episodes of renal colic and urinary passage of small stones with an unusual morphology despite previous surgical removal of the parathyroid adenoma. A complete diagnostic workup ought to be able to establish the type of stones, but contemporary medicine, with its reliance on protocols, procedures and scientific evidence, may have lost sight of the importance of good communication with the patient. (narrative nephrology), non disponibile (narrative nephrology)

Phenotypic variation in four natural populations of Parrotia persica (Hamamelidaceae), a species considered a living fossil endemic to the Hyrcanian forest, was evaluated through leaf morphometric and multivariate analysis. Furthermore, plasticity and leaf fluctuating asymmetry (LFA) were studied. Our findings clearly displayed significant divergence among sites. The smallest lamina size, the highest plasticity, and the lowest LFA values were recorded in the eastern and more xeric sites (Ghorogh and Daland), thus it seems these sites endure a larger environmental stress. Although our findings showed that multivariate and leaf morphometric analyses are suitable instruments to detect levels of phenotypic variability among P. persica natural populations, further study of allozyme and DNA diversity is necessary., Se evaluó la variación fenotípica en cuatro poblaciones naturales de Parrotia persica (Hamamelidaceae), una especie endémica considerada como un fósil viviente del bosque hircaniano, a través de un análisis morfométrico y multivariado de las hojas. Asimismo, se estudiaron la plasticidad y la asimetría foliar fluctuante (AFF). Nuestros hallazgos mostraron claramente una divergencia significativa entre sitios. El tamaño más pequeño de la lámina foliar, la plasticidad más grande y los valores más pequeños de AFF fueron registrados en los sitios más xéricos de la parte oriental (Ghorogh y Daland), por lo que parece que estos sitios están sujetos a un mayor estrés ambiental. Obtuvimos resultados interesantes, pero hace falta realizar nuevos estudios de la diversidad de aloenzimas y ADN.
