Side Arm Homicide in the Italian Province of Trieste between 1953 and 2002

The authors present a complete overview of the phenomenon of side arm homicide, basing the study on the data collected at the Forensic Pathology Unit of the University Of Trieste School Of Medicine. Side arms are the most frequently used homicidal method in the town and province of Trieste in a considered study period of 50 years from 1953 to 2002. The analysis of the collected data shows that the town and province of Trieste are communities still very well disjoined from a reality in which crimes against life are yet very uncommon occurrences. This conclusion is well supported by the fact that it has not been possible to define a category of potential victims, which is on the contrary quite easy among societies where organized crime is consistent and widespread. The popularity of side arm as homicide method in our province supports the hypothesis that these crimes are often not aforethought murders, perpetrated by subjects often afflicted by recorded mental health problems, acting during an insanity raptus. Knives are not only actually the easiest weapons to obtain in a household, but are very easily used as well, even by the subjects not accustomed to handle weapons

Pathological Fractures Of The Jaws Due To Cystic Lesions: A Three Case Series With A Brief Review Of The Literature

This study aims to describe pathologic fractures of the jaws due to cystic bone lesions. Their daily clinical practice findings are not very common, so their treatment can be challenging. In addition, endosseous benign lesions like a radicular, residual, solitary, aneurysmal cyst, and odontogenic keratocyst, might weaken the bone so that trauma, or usual chewing, could break it. We follow from the first clinical examination to the X-ray or CBCT examination and surgical management of our patients, reporting all procedures and results to explain our approach to these cases. We also reviewed the literature briefly to determine if our operative management is in line with the scientific community. Mandibular angle and body are common locations, while symphysis and condyle are less so. Young men are the most affected, and trauma is the most triggering event. Cyst enucleation, followed by fracture reduction and fixation, is the treatment of choice for our clinical team and the scientific community. We observe how impactful it is to approach the cavity of the cystic lesion from the fracture line as the surgical gold standar

Observational Study on the Preparation of the Implant Site with Piezosurgery vs. Drill: Comparison between the Two Methods in terms of Postoperative Pain, Surgical Times, and Operational Advantages

Purpose. Recent advances show that ultrasonic implant site osteotomy is related to a decreased trauma and a better postoperative healing of the surgical site when compared to traditional drilling techniques. The micrometric bone cutting control and the operative advantages related to the piezoelectric approach are also characterized by a learning curve for the clinician in surgical practice and an increased operative duration of the procedure. The aim of this investigation is to compare the operative time, the postoperative pain, and the amount of painkillers taken by the patient during the healing period. Methods. A total of 65 patients were treated at the Unit of Oral Surgery (Department of Medical Sciences, Surgery and Health, University of Trieste, Italy) using a split mouth model: 75 drill-inserted implants (G1) and 75 piezoelectric device-inserted implants (G2) were placed. The Visual Analogue Scale (VAS) was performed to evaluate the postoperative pain at 15 days from surgery. The operative time and frequency of intake of painkillers were measured. Results. The G1 and G2 groups showed a significant difference with a higher use of painkillers observed for G1. The G2 patients showed a lower level of pain (VAS) at all experimental times between 8 hours to 7 days (p<0.01) postsurgery. At 15 days, the pain levels were similar for both groups. No differences were found in site preparation duration between the study groups. Conclusions. The evidence supports the application of the piezoelectric approach compared to the drill's osteotomy as a useful technique for implant site preparation. This trial is registered with NCT03978923

Influence of pretreatment with PRF (platelet rich fibrin) on wettability of implant surface

Aim: The objectives of this study were three: 1) obtaining electronic microscopy images before and after a PRF pretreatment from three different implant surfaces, 2) evaluating the angle contact obtained wetting, with a blood drop, three different implant surfaces and 3) evaluating if the PRF pretreatment of the same implant surfaces, modifies their wettability. Methods: Six implant surface\u2019s samples were selected: two machined, two blasted and two with laser treatment. Four images for implant surface were acquired by SEM (Scanning Electron Microscope) before and after a PRF pretreatment, respectively with 200x, 500x, 1000x and 2000x magnification. Afterwards the angle contact formed between three different implant surfaces and 10\u3bcl blood drop was calculated by optical microscope with 10x magnification. With other three samples, that were pretreated with PRF, the angle contact formed between the different implant surfaces and 10\u3bcl blood drop was evaluated by the same microscope. The pretreatment of the implant surfaces was made soaking the samples in the PRF and after drying them with sterile gauze. The entire procedure was performed five times in five different days to obtain five measurements for implant surface with and without the PRF pretreatment. The human blood, for the drops and for the PRF production, was drawn from the same volunteer for all the time. Results: The results obtained with SEM were poorly relevant. It was possible to observe only a few fibrin deposits on implant surfaces with PRF pretreatment. The results obtained with optical microscopy, evaluating different surfaces between them, were relevant: by using \u201cnon parametric\u201d tests with software SPSS for Mac OS X (SPSS inc. Chicago, IL, USA) a significant wettability difference from different implant surfaces was observed. The average angle contact of the different surfaces were: for the machined surface 56.58 \ub1 12.83, for the sandblasted surface 76.45 \ub1 6.93 and for laser treated surface 51.02 \ub1 3.49. The results obtained, calculating the angle contact after PRF pretreatment of implant surfaces, were very interesting and satisfying. It was possible to observe an important wettability improvement of implant surfaces: machined surface had 33.67 \ub1 3.06, sandblasted surface had 38.84 \ub1 8.49 and laser treated surface had 32.88 \ub1 1.59. The statistical analysis highlighted a significant wettability difference from the same implant surface before and after PRF pretreatment but there was not significant angle contact difference between the different surfaces after PRF pretreatment; in fact the angle contact values were very similar Conclusions: Compelling evidence from our study lead us to suggest, according to scientific literature, that the machined surfaces have more wettability than sandblasted surfaces and a similar one compare to the laser treated surfaces. The PRF pretreatment have a positive effect on wettability of implant surfaces. This effect is independent from the kind of surface, probably because the wettability improvement is directly related to PRF proprieties and not to the characteristics of the implant surface even if the results with SEM were not significant; perhaps due to chemical changes on implant surfaces (not visible by microscopy) thanks to PRF pretreatment. So the PRF could be used as a helper to make the osseointegration process faster by using a rough surface, which stimulates the cell differentiation, with an optimal wettability, which allows to improve the cell adhesion
