Populations of Monacha atacis from southern Occitania in France and of M. samsunensis from northern Anatolia in Turkey (Atakum/Samsun and Kastamonu) were investigated by an integrative approach based on morphological (shell and genitalia) and molecular (mitochondrial and nuclear gene sequences) features. Morphological examination revealed a complex pattern of variation within and between geographically separated populations, while molecular analysis showed strong similarity between the two species, confirming earlier suggestions that the species are conspecific. Pfeiffer’s name Helix samsunensis introduced in 1868 has priority over the name M. atacis given by Gittenberger & de Winter in 1985.

Plant trade and exchange for horticulture, recreation or research play a significant role in the dispersal of molluscs. Alien slugs and snails accidentally introduced into Europe have established rich communities in several countries, but although these introductions could have ecological and economic implications, mollusc xenodiversity in Italian botanical gardens, plant nurseries, and greenhouses has never been investigated. Facilities throughout the country were therefore visited between 2017 and 2023. Here the list of the achatinoidean species so far recorded from Italian greenhouses is provided, giving a short description of their diagnostic characters. The greenhouses of Trento and Padua host interesting assemblages of achatinoideans: the results of this study include the first reports of four achatinids, namely Allopeasclavulinum , Opeashannense , Paropeasachatinaceum and Subulinaoctona from Italy and the first record of Geostilbiaaperta from Europe. Reproductive anatomy of all species except Geostilbiaaperta is illustrated in detail, integrating anatomical knowledge of this group of tiny molluscs, some of which are known mainly from their shell characters. The systematics of all the species is discussed, highlighting topics for future research (e.g., status of Allopeasmauritianum , real identity of Helixhannense , anatomy of Opeashannense , species-level taxonomy of Subulina , systematic relationships and species-level taxonomy of Geostilbia )., Competing Interests: The authors have declared that no competing interests exist., (Giuseppe Manganelli, Andrea Benocci, Debora Barbato, Folco Giusti.)

Features of shell and genitalia as well as nucleotide sequences of selected mitochondrial and nuclear genes of specimens of Monachacantiana from ten northern French and two Dutch populations were compared with the same features of British and Italian populations. They were found to be very similar to populations previously identified as belonging to the CAN-1 lineage of M.cantiana . This confirms previous suggestions that M.cantiana was introduced to western Europe (England, France and the Netherlands) in historical times., Competing Interests: The authors have declared that no competing interests exist., (Joanna R. Pieńkowska, Giuseppe Manganelli, Małgorzata Proćków, Debora Barbato, Katarzyna Sosnowska, Folco Giusti, Andrzej Lesicki.)

Background: Proper umbilical cord stump care during the first days of life (both in hospital and at home) should not be overlooked to prevent possible complications (e.g., purulent discharge, granulomas, or periumbilical erythema or omphalitis). Despite the known benefits of its correct execution, the care of umbilical cord stump remains controversial, and many different approaches are described. The World Health Organization suggests the use of dry cord stump care (easy and economic technique) in developed countries, but in many cases in the real life various topical antiseptics are used in combination with dry cord stump. The extracts of Arnica Montana (AM) have been reported to possess antibacterial, anti-inflammatory, antifungal, and immunomodulatory activities, very useful in the management of cord stump in full term infants., Methods: In our study we evaluated the efficacy of a powder containing AM (study group- GrA) versus dry cord stump (control group-GrB) in a population of healthy newborn >35 weeks of gestational age (GA)., Results: Three hundred twenty-six neonates (mean GA 39±1 in both groups and body weight 3200 g and 3400±448 g respectively in GrA and GrB) were enrolled in two standard neonatal care units (163 neonates in GrA and 163 in GrB). At T1 (48 hours after discharge) GrA showed significantly reduced incidence of mild complications in toto, in particular a lower rate of wet umbilical cord stump). No differences between the two groups at T2 (1 week after discharge)., Conclusions: The use of a natural topical dermo-protective powder containing AM reduces the risk of minor complications, both nurse and parental workload in the first days after discharge, but does not have an impact on cord detachment and other complications in neonates >35 weeks GA.
