Support Immersion Endoscopy in Post-Extraction Alveolar Bone Chambers: A New Window for Microscopic Bone Imaging In Vivo.
Using an endoscopic approach, small intraoral bone chambers, which are routinely obtained during tooth extraction and implantation, provide visual in vivo access to internal bone structures. The aim of the present paper is to present a new method to quantify bone microstructure and vascularisation in vivo. Ten extraction sockets and 6 implant sites in 14 patients (6 men / 8 women) were examined by support immersion endoscopy (SIE). After tooth extraction or implant site preparation, microscopic bone analysis (MBA) was performed using short distance SIE video sequences of representative bone areas for off-line analysis with ImageJ. Quantitative assessment of the microstructure and vascularisation of the bone in dental extraction and implant sites in vivo was performed using ImageJ. MBA revealed bone morphology details such as unmineralised and mineralised areas, vascular canals and the presence of bleeding through vascular canals. Morphometric examination revealed that there was more unmineralised bone and less vascular canal area in the implant sites than in the extraction sockets

L’applicazione delle pene sostitutive nel patteggiamento tra iniziativa delle parti e poteri del giudice = The Application of Alternative Punishments in Plea Bargain Between Parties’ Initiatives and Judge’s Powers = La aplicación de las penas sustitutivas en el procedimiento de admisión de responsabilidad por iniciativa de las partes y los poderes del juez
La riforma Cartabia ha ristrutturato dalle fondamenta il sistema delle pene sostitutive, anche nei suoi aspetti processuali, e il patteggiamento si pone quale luogo elettivo per la loro applicazione. Tuttavia, nella disciplina del rito, il legislatore si è limitato a introdurre, accanto a una generica disposizione, un rinvio all’applicazione delle
disposizioni relative al c.d. sentencing nel procedimento ordinario, in quanto compatibili. Spetta così all’interprete ricostruire le prerogative delle parti e, soprattutto, i poteri del giudice, in un procedimento dominato dalla logica negoziale. In questa prospettiva, il contributo mira ad analizzare le diverse tipologie di richieste formulabili dalle
parti, in relazione al loro grado di completezza, e a delimitare, per ciascuna di esse, gli eventuali spazi d’intervento del giudice nelle scelte sulla pena sostitutiva e sui suoi contenuti. Ciò, vagliando la compatibilità delle soluzioni ermeneutiche con i principi che governano il rito negoziato e con le esigenze di coerenza e di tenuta del sistema.The so called “Cartabia Reform” restructured the system of alternative punishments from its foundations,
including its procedural aspects, and plea bargain stands as the elective place for their application. However, in
the regulation of the procedure, the legislature merely introduced, alongside a generic provision, a reference to
the application of the provisions regarding the so-called sentencing in the ordinary proceeding, insofar as they
are compatible. Therefore, it is up to the jurist to reconstruct the rights of the parties and, above all, the powers
of the judge, in a procedure dominated by the logic of negotiation. In this perspective, the author aims to analyse
the different types of requests that can be formulated by the parties, in relation to their degree of completion, and to delimit, for each of them, the possible spaces of intervention of the judge in the choices on the alternative
punishment and its contents. Finally, the author intends to examine the compatibility of the solutions with the
principles that govern the plea bargain and with the requirements of coherence and tightness of the system.La reforma Cartabia ha reestructurado desde los cimientos el sistema de penas sustitutivas, incluso en sus

disposición genérica, una remisión a la aplicación de las normas relacionadas con el denominado sentencing en

prerrogativas de las partes y, sobre todo, los poderes del juez en el procedimiento de admisión de responsabilidad,
dominado por la lógica negociadora. Desde esta perspectiva, el artículo tiene como objetivo analizar los diferentes
tipos de solicitudes que las partes pueden formular en relación con su grado de completitud, y delimitar, para
cada una de ellas, los posibles espacios de intervención del juez en las decisiones sobre la pena sustitutiva y su
contenido. Lo anterior, evaluando la compatibilidad de las soluciones interpretativas con los principios que rigen

The use of cortical particulate allograft mixed with plasma-rich fibrin in severe maxillary alveolar ridge atrophy
Atrophy in the edentulous maxilla typically consists of vertical bone loss in the posterior maxilla due to pneumatization of the maxillary floor and transverse reduction in anterior areas. The purpose of this study was to perform bilateral sinus floor augmentation and maxillary alveolar bone reconstruction by autologous platelet-rich fibrin (PRF) mixed with mineralized cancellous bone allograft and PRF membranes. Method: Six patients (3 men and 3 women, age 46-65 years) with severe maxillary atrophy were selected for this study. The patient's blood was centrifuged to obtain PRF. Mineralized cancellous bone allograft (Zimmer Puros (R)) was mixed with PRF and applied for sinus floor augmentation in posterior and lateral augmentation in anterior maxillary atrophy. Additionally, PRF membranes were placed over augmented area. Evaluation was carried out before and six months after surgery using CBCT to measure alveolar site dimension. Histology was obtained from corebiopsies taken for implant insertion to evaluate quality of bone regeneration. Results: The use of PRF as cover membrane permitted rapid tissue reparation, high bone quality was detected in sites augmented with bone allograft and PRF. The horizontal alveolar bone volume after 6 months and the vertical bone augmentation increased at about 10 mm. Conclusion: Based on the preliminary case series, the combination of PRF membrane and PRF mixed with bone allograft represents a predictable method of augmenting the sinus floor as well as the deficient anterior maxilla to achieve rehabilitation of the atrophic maxilla with dental implants

External validity of definition of rehabilitation in health
Background. A definition of rehabilitation in health (medical rehabilitation) (RIH-MR) must be valid both for those in and out of the field. In scientific papers, internal validity refers to the possibility of a study to explain its findings without biases, external validity to generalizability of results to other contexts.
Here we consider the first the possibility to describe with the definition all what we do in RIH-MR, and the latter the possibility to rule out anything that is not RIH-MR.
In Cochrane Rehabilitation (CR) we first faced the problem when a Cochrane Systematic Review (CSR) on Penile Rehabilitation was published. The review dealt only with drugs; we considered inappropriate the use of the term rehabilitation but lacked a definition of RIH-MR to confirm our thesis.
Objective. the aim was to quantify the phenomenon looking at all the CSRs claiming to study rehabilitation and comparing to the definitions provided by CR, PubMed (Mesh Term) and the author judgment.
Methods: We performed a search of the all CSRs published in the Cochrane Database of Systematic Reviews with the presence of the term “rehabilitation” in the title. Exclusion criteria were: editorial, updated CSRs, withdrawn CSRs. A content analysis of the CSRs included/excluded by each classification was performed. For each field/intervention, the author judged the classifications of CR and PM coherent if all CSRs were included or excluded, incoherent if some CSRs were included and other excluded.
Results: Out of 14,816 records, we found 139 papers with the term rehabilitation in the title. We analyzed 89 CSRs and CR included 94.4% of CSRs, the author 91%, PubMed only 50.5%. 4 reviews and Cancer and vestibular rehabilitation fields were judged non-RIH-MR by all classifications. CR incoherently excluded one review related to exercises cardiac rehabilitation. The author excluded 4 reviews included by CR as the provided interventions were not considered rehabilitation. All the other CSRs were judged consistently by CR and the author. Only the neurological field was coherently included by PM, albeit excluded in all cases with application of cognitive and neuropsychological interventions. We did not find coherence for all the other fields and interventions.
Conclusion. The results highlight the possibility to exclude “single interventions” from the definition, even if they are classically considered in the field of rehabilitation. Consequently, we could provide a definition of “rehabilitation intervention”, and this could be considered in terms of the professionals providing the intervention.
