Contribution to floristic knowledge of Middle Latina Valley (Lazio - Central Apennines)
Full text linkIn this paper the Authors show the preliminary results of a floristic research on the Latina Valley in Lazio Region. This research was carried out in the period 2009-2011. Amongst the about 500 species recorded, 50 entities are to be considered rare for the Latium region. In particular for the following taxa: Isoëetes duriei, I. hystrix, I. velata, Exaculum pusillum, Cicendia filiformis, Radiola linoides, Bellevalia trifoliata this paper represents their first record for inland zones since at present they were known for coastal areas only
Gagea tisoniana, a new species of Gagea Salisb. sect. Gagea (Liliaceae) from central Italy
No full textGagea tisoniana Peruzzi et al. sp. nov. is described and its taxonomic relationship is discussed. The new species, which appears endemic to C Italy, is close to G. pratensis (Pers.) Dumort., G. pusilla (F. W. Schmidt) Sweet and to other mainly poorly known (i.e. G. succedanea Griseb. et Schenk, G. transversalis Stev., G. paczoskii (Zapal.) Grossh.) or as yet undescribed taxa from E Europe and E Mediterranean area. The recognition of the new taxon G. tisoniana is claimed on the basis of anatomical, karyological, ecological and phytogeographical data. Maps of the Italian distribution of G. pratensis (2n = 60), G. pusilla (2n = 24) and G. tisoniana (2n = 24) are presented, together with an analytical identification key. Finally, G. pratensis is here recorded for the first time in Tuscany (Monte Cetona)

che, nell'ambito dd versante laziale dei Monti della Laga erano stati sino ad oggi solo
parzialmente indagati. Si tratta in particolare dd sito umido di Fosso Cerruglia,
dd vallone di Sdva Grande e delle praterie montane e subalpine di Macchie PianePizzo
di Sevo. Daile diverse campagne di rilevamento floristico condotte nd periodo
1997-2000 sono emersi interessanti risultati che hanno portato alia segnalazione
di un'entita nuova per Ia catena appenninica, di 11 entita nuove peril Lazio, di 13
taxa non ancora indicati per i Monti della Laga e nuove stazioni di altre 80 specie
gia note per il territorio, alcune delle quali rare o rarissime almeno nd Lazio. Per le

The use of knee mega-prosthesis for the management of distal femoral fractures: A systematic review
No full textIntroduction
Distal femur fractures (DFFs) are unusual and difficult to deal, especially in elderly patients. A consensus about a gold-standard treatment has not been reached yet. Available options include both conservative and surgical management. In elderly patients a prosthetic replacement could be a valid treatment option. Literature is lacking about the use of mega-prosthesis in this type of fractures. The purpose of the present systematic review is to examine which fracture, both acute and chronic, involving distal femur should be treated by using a mega-prosthesis.
Materials and Methods
Studies were identified by searching electronic databases. All studies that enrolled people of any age affected by a DFFs treated by using a megaprosthesis were included. Primary outcomes of the present reviews were: ROM, functional assessment and complications. Two review authors independently selected eligible trials. Disagreements at any stage were resolved by consensus or a third party adjudication. Descriptive statics was used to summarize the data.
Results
Thirteen article were finally included in the review. One hundred-four patients were treated with knee megaprosthesis. Three categories of patients were identified: 29 patients were affected by supracondylar femur fracture; 51 patients occurred with a periprosthetic fracture; 24 patients suffered a non-union of a previous supracondylar fracture. The follow-up varied between 6 months to 58 months. All studies showed good results in terms of improving quality of life, resuming activities of daily living (ADLs), early mobilization, ROM, shorter hospital stay. Although not frequent, the only reported complications were infection and aseptic loosening.
Discussion
The present review showed that the use of knee megaprosthetic implants could represent a valid treatment option aiming to reduce patients’ immobilitazion and hospital stay. Good clinical outcomes with low rate of complications were reported by all included studies. Literature is lacking about long-term outcomes and complications. Moreover studies comparing knee prostheses and other types of surgical treatment (intramedullary nails, plate fixation system) are needed.
Conclusions
Megaprosthesis represent a viable treatment option in patients affected by DFFs (either acute, periprostethic or non-union) because they allow immediate weight-bearing, shorter hospital stay, a fast recovery of knee function and ADLs
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
