No full textGli Autori, dopo aver esaminato gli aspetti clinici dei tumori vescicali superficiali, con particolare riguardo alla storia naturale della neoplasia, prendono in rassegna i principali barèmes nazionali e internazionali in uso in ambito di responsabilità civile.
Viene quindi elaborata, sulla base delle tabelle di rischio utilizzate in ambito di urologia oncologica, una proposta valutativa del danno biologico in relazione allo stadio della neoplasia, al grading istologico e ad altri fattori prognostici
DENTAL ROOT SURFACE TREATMENT WITH ETHYLENEDIAMINETETRAACETIC ACID DOES NOT IMPROVE ENAMEL MATRIX DERIVATIVE PEPTIDE TREATMENT WITHIN INTRABONY DEFECTS: A RETROSPECTIVE STUDY
No full textIntroduction
The dental root surface treatment is quite often considered a key factor in achieving regeneration of the periodontal defect. The aim of this retrospective study was to compare the 12-month clinical outcomes obtained by the application of enamel matrix derivative peptide (EMP) with and without EDTA dental root conditioning in intrabony 2-3-wall defect treated by minimally invasive surgical therapy (MIST).
Material and Methods
Twenty-two healthy patients, affected from moderate or severe chronic periodontitis, with a 2-3-wall intrabony defect (≥4 mm deep and ≥2 mm wide), were selected. Each patient was treated by MIST Technique and EMP was applied into the defect during the surgery, on the dental roots. However, in the treatment group-1 (TG1) the root surfaces were not previously conditioned whilst in the treatment group-2 (TG2) root surfaces were conditioned by EDTA. Immediately before surgery (T0) and 12-month after (T2) the probing depth (PD) and gingival recession (GR) were registered at the experimental sites and the full-mouth plaque score (FMPS) and full-mouth bleeding score (FMBS) were also registered.
Results
No statistically significant differences were shown between TG1 and TG2 at T0 and T1 in term of PD, GR, FMPS while a statistically significant greater FMBS was recorded in TG2 at T1. PD, FMPS and FMBS indices significantly decreased between T0 and T1 both in TG1 and TG2 (p<0.05). GR increase resulted not statistically significant both in TG1 and TG2 (p<0.05) between T0 and T1.
Conclusions
In this retrospective study both the treatments achieved favourable and comparable clinical results. The PD and GR were similar between the two treatment groups (TG1 and TG2) in the single phases considered (T0 and T1) and during the follow-up (T0-T1). The EDTA conditioning of dental root surfaces did not seem efficient to improve the clinical results in the treatment of 2-3-wall periodontal defects
The use of only enamel matrix derivative allows outstanding regeneration results in periodontal intrabony defect treatment: a retrospective study
No full textPeriodontal tissue regeneration depends on several biological, homeostatic and regulative variables that directly induce the clinical features. The aim of this study is to compare the clinical results obtained using the enamel matrix derivative peptide (EMP) compared to the less manageable association of EMP and bovine bone xenographic (BPBM) in the treatment of deep intraosseous defects. Ten healthy patients, suffering from moderate or severe chronic periodontitis, having at least two deep and narrow intrabony defects in the same dental arch and needing surgical treatment, were selected. The same patient was treated with the two different materials: EMP -TG1 in one defect and the association-TG2 in the other. Immediately before surgery (T0) and 12-month after (T2) the probing depth (PD) and gingival recession (GR) were registered at the experimental sites. No statistically significant differences were shown between TG1 and TG2 at T0 nor at T1 in term of PD and GR, while a statistically significant PD decrease was found both in TG1 and TG2 between T0 and T1 (p less than 0.05). GR increase resulted statistically significant in TG1 (p less than 0.05) but not in TG2 between T0 and T1 (p≥0.05). In this split-mouth retrospective study, both the treatments achieve favourable clinical results but the TG1 shows a significant increase in GR probably because EMP is not able to support the gingiva covering the intrabony defect. Therefore, the choice of the type of periodontal defect to be treated with EMP will be a therapeutic key-point
A new histological method to study oral soft tissue penetrability to iodine and optimize oral use of iodine solutions
No full textThe aim of this work is to establish a histological method to fix iodine inside slides of treated oral mucosa more permanently in order to allow section counterstaining and facilitate improved clinical and experimental studies on iodine penetration. Transforming iodine into a stable histological formation inside tissues is particularly useful for histological analysis of clinical and experimental iodine treatments. In the field of oncology, this method can be applied to povidone-iodine-treated (human or animal) mucosa or skin, to organs treated with iodine tincture or Lugol’s solution, to oral lesion detection and to mucogingival junction identification
Le lesioni renali nei traumi chiusi toraco-addominali: casistica del settorato medico-legale parmense negli anni 1970-2006
No full textSono stati analizzati 307 casi di lesioni renali rilevate in 1599 traumi chiusi toraco-addominali estrapolati da 8581 indagini autoptiche eseguite nel corso degli ultimi 37 anni (1970-2006) presso la Sezione di Medicina Legale del Dipartimento di Anatomia Umana, Farmacologia e Scienze Medico-Forensi dell'Università degli Studi di Parma.
Di ogni caso sono stati ricavati, oltre all'età, al sesso e ai dati circostanziali, la sede della lesione renale ed il quadro anatomo-patologico macroscopico del rene.
Dall'esame della nostra casistica emerge che il rene, sebbene goda di una certa protezione per la sua posizione retroperitoneale alta all'interno della loggia adiposa, protetto dalel ultime coste, e fra i visceri addominali anteriormente ed i muscoli del dorso posteriormente, è interessato da lesioni in corso di traumi chiusi toraco-addominali con una frequenza abbastanza elevata, pari al 19,20%.
Per la classificazione anatomo-patologica delle lesioni renali abbiamo fatto riferimento sia ai vari tipi di lesione renale (infiltrazione emorragica, ematoma, lacerazione superficialie, frattura, rottura, spappolamento) evidenziabili in sede autoptica che alla sede autoptica, che alla sede (capsula adiposa perirenale, parenchima, vasi dell'ilo) in cui le stesse sono state evidenziate
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
