S. gallolyticus Aortic Valve Endocarditis with Mitral Valve Leaflet Aneurysm
S. gallolyticus is one of the pathogenic agents of endocarditis, and mitral valve aneurysm is a rare but potentially devastating complication. We present a case of S. gallolyticus aortic valve endocarditis with concomitant anterior mitral valve leaflet aneurysm. Patient underwent surgery before aneurysm perforation, and postoperative course was uneventful. Time of surgery is crucial to avoid severe complications due to aneurysm rupture

Does Corporate Social Responsibility Affect the Performance of Firms?
Over the last two decades in OECD countries increasingly more firms are certifying as Socially Responsible (CSR is the acronym for Corporate Social Responsibility). This kind of certification is assigned by private companies that guarantee that a certain firm’s behaviour is environmentally and sociologically correct. Some papers (including Preston and O’Bannon, 1997; Waddock and Graves, 1997; McWilliams and Sieger, 2001; Ullman, 1985) tried to establish if there exists a link between Social Responsibility certification and the performance of firms. Their results were ambiguous and did not show any common connection. This ambiguity depends mainly on the static nature of their analyses and on the problem of whether performance is affected more by certification costs or by increasing sales due to an effect on reputation. Our work would like to discover whether certain performance indicators are affected by a firm’s social responsible behaviour and their certifications by looking at panel data. The novelty of our analysis is due to its dynamic aspect and from a CSR index that intersects two of the three main international indices (Domini 400 Social Index, Dow Jones Sustainability World Index, FTSE4Good Index), to be objective and obtain a representative sample. The main results seem to support the idea that CSR firms which are more virtuous, have better long run performance. They have some initial costs but obtain higher sales and profits due to several causes reputation effect, a reduction of long run costs and increased social responsible demand.Corporate Social Responsibility, Growth
Masseteric cooptation and crossfacial nerve grafting: Is it still applicable 22 months after the onset of facial palsy?
Background: Eighteen months is usually considered the cutoff time within which recovery of the mimic muscle remains possible using facial nerve cooptation. Few reports on the use of cooptation after this interval have appeared. Purpose of this study is to investigate the feasibility of this procedure also after 22 months. Methods: Six patients treated via crossfacial nerve grafting between healthy and paralyzed middle and middle-upper facial nerve branches and masseteric cooptation of the main trunk of the paralyzed facial nerve between 20 and 24 months after the onset of palsy were analyzed. Population consisted of two males and four females ages 8-42 years (mean 24 years). Facial palsy developed after acoustic neuroma resection in three patients, after the removal of a cerebellopontine angle astrocytoma in one, and as a consequence of Bell's palsy or cerebral hemorrhage in the other two (one each). House-Brackman and Sunnybrook clinical evaluation systems and FDI questionnaire were used to assess results. Results: House-Brackman scores changed from VI before the operation for all patients to II for two patients and III for four patients. Sunnybrook scores were 0-10 before the operation, but 62-84 at the last visit. Mean FDI scores moved from 24 to 38.5 meaning a statistical high significant improvement (P < .01). Conclusions: Masseteric/crossfacial nerve grafting is feasible for patients with palsies 20-24 months in duration, affording satisfactory functional and esthetic results and a dramatic improvement in quality of life

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Masseteric nerve for gracilis muscle re-innervation in unilateral facial palsy: Impact on quality of life
Unilateral established or congenital facial palsies are usually treated with neuromuscular transplantation to reanimate the impaired side of the face. One of the most debated points is the motor nerve to choose for the reinnervation of the transplant. Contra-lateral healthy facial nerve is usually preferred, but in selected cases motor nerve to masseter is considered a valuable option. However only a few clinical studies focused on quality of life in this subset of patients are available in literature
