The aim of the present study was to evaluate surface alterations on titanium implant necks subsequent different prophylaxis procedures. Fifty ITI implants were utilized. Forty treated with 10 procedures (ultrasonic scaler, plastic tip ultrasonic stainless steel curette, teflon air powered system, abrasive rubber cups, polishing cup and brush), left as untreated controls. Surface studied an area 1mm×0.9mm quantified using optical microscopic, SEM laser prophylometer analysis. use provided...
Severe combined immunodeficiencies (SCIDs) are a group of inborn errors the immune system, usually associated with severe or life-threatening infections. Due to variability clinical phenotypes, diagnostic complexity and heterogeneity genetic basis, they often difficult recognize, leading significant delay (DD). Aim this study is define presenting signs natural history SCID in large cohort patients, prior hematopoietic stem cell gene therapies. To purpose, we conducted 30-year...
A retrospective study is presented to correlate the inter-judge consistency for different psycho-perceptual parameters of recently proposed Impression Noise Fluency Voicing (INFVo) perceptual rating scale substitution voices, and vocal function as perceived by patient.The Voice-Related Quality Life (V-RQoL) Self Evaluation Communication Experiences After Laryngectomy (SECEL)-a self-evaluation questionnaire communicative experience after laryngectomy surgery-were administered 89 total...
Several guidelines on adeno-tonsillar disease have been proposed in recent years and some discrepancies relation both to clinical manifestations indications for surgical treatment emerged. The aim of the study was verify what influence (adeno)-tonsillectomy had behaviour ENT specialists Italy. Our is a retrospective multi-centre case series with chart review.The survey involved 14,770 children, aged between ages 2 11, who undergone surgery 2002 2008 fourteen Italian tertiary secondary...
Here we describe the findings of a unique example early techniques adopted in neurosurgery around 5000 years ago, consisting double well healed skull trephination associated with post-cranial traumatic event occurring intra vitam to young male from Early Chalcolithic cemetery Pontecagnano (South Italy, ca. 4,900 - 4,500 cal BP). Morphological, X-ray and 3D-CT scan skull-cap evaluation revealed that main orifice was produced by scraping, obtained clockwise rotary motion right-handed surgeon...
The analysis two-phase flow inside centrifugal pumps is a fundamental issue in several engineering applications. This often represents bad working condition with respect to single phase one, causing head reduction, efficiency decrease, and higher operational costs terms of energy money. paper reports numerical bubbles behavior pumps. Equations regulating the air bubble motion within rotor pump have been solved considering effects all forces acting. Coalescence phenomena investigated too,...
The aim of this paper is to illustrate a methodology for identifying and analysing the performance an I.C. engine and, at same time, reconstruction morpho-dynamical vibration. Some technical considerations real application explain method by completing description phenomena observed. It allows focus which should concur improvement diagnostics anomalies useful determining correct operating process engine.
Several studies were conducted previously on fuel and biofuel performance of micro-turbines. The present paper combines experimental statistical approaches to study the vibrational behavior a gas micro-turbine supplied with different pure fuels admixed rapeseed oils. Experimental tests carried out at operating conditions have allowed us build classification model through using discriminant analysis. can distinguish occurring when turbine is fueled kerosene, or diesel oil. Moreover,...
Optimizing heat transfer in the evaporator tubes is essential for obtaining optimal coefficients. Deviation from ideal nucleated boiling configurations can lead to rapid transitions film conditions, compromising exchange Detecting critical bubble flow conditions invaluable preventing thermal overloads and safeguarding operational integrity. The aim detect type of motion established ducts using non-intrusive techniques. To achieve this aim, accelerometric devices vibrations induced by passage...
Excessive vertical growth of the posterior dentoalveolar region has been implicated in etiology so-called long-face syndrome. In this study, we tested hypothesis that molar heights are positively related to craniofacial features. Cephalometric measurements obtained from 82 adult subjects were entered as independent variables a multiple regression model. Maxillary and mandibular dependent variables. Approximately 70% total variance was explained by anterior lower facial height (ANS-Me)...
Abstract Background Very few reports have investigated the role of cell cycle regulators as biomarkers in Basaloid Squamous Cell Carcinoma (BSCC) larynx, a definite morphologic, uncommon, very aggressive variant squamous carcinoma. Lower expression Ki67/Mib-1, proliferation marker highly expressed majority tumours, and p53, tumour suppressor protein that can induce an arrest G1-S transition, was related to better prognosis laryngeal BSCC. In head neck, p27 kip1 , member Cip1/Kip1 family...
Considerations about heat generation, wear, and corrosion due to some macrostructural bur components (e.g., cutting lips, rake angle, flute, helix angle) have been widely reported. However, little is known how the microstructural of implant drill surface can influence lifetime clinical performance.To investigate accurately morphology surgical bone drill, by means multivariate multidimensional statistical analysis, in order assess roughness parameters able predict evolution tribological...
Otorhinolaryngologic manifestations are common in 22q11.2 deletion syndrome (22q11.2DS), but poorly described. This study aimed to better define the ear‐nose‐throat (ENT) phenotype of 22q11.2DS patients, attempt best detect subjects requiring subspecialist intervention. We enrolled 25 patients affected with 22q11.2DS. Anatomic and functional ENT findings were investigated using clinical, laboratory, instrumental data. Immunophenotype frequency infections evaluated. Univariate multivariate...
This study aims at verifying relationships between the perception of medico-legal risks involved in professional activity Italian otolaryngologists, defensive medical behaviour and their understanding liability insurance matters civil liability. One hundred specialists replied to a questionnaire pertaining psychological impact issues specific queries regarding coverage, either privately stipulated or provided by employer. Statistic analysis was carried out χ(2) test ANOVA multiple variance...
Background: Permanent tracheostomy because of total laryngectomy surgery entails great conse-quences for the patient regarding respiratory physiopathology such as filtering, humidifying, and heating function air by nose is lost. The use special stomal filters can determine adequate protection trachea-broncho-pulmonary system with a reduction in pathologies. In fact, most cases laryngectomee patients are first cigarette smokers who this reason already have also diseases chronic obstructive...
Detecting the ultrastructure of brain tissue in human archaeological remains is a rare event that can offer unique insights into structure ancient central nervous system (CNS). Yet brains reported literature show only poor preservation neuronal structures. Using scanning electron microscopy (SEM) and advanced image processing tools, we describe direct visualization vitrified spinal cord which discovered male victim AD 79 eruption Herculaneum. We exceptionally well preserved neurons from...
