Ambivalent emotional experiences of everyday visual and musical objects.

2019

Art brings rich, pleasurable experiences to our daily lives. However, many theories of art and aesthetics focus on specific strong experiences—in the contexts of museums, galleries, and concert halls and the aesthetic perception of canonized arts—disregarding the impact of daily experiences. Furthermore, pleasure is often treated as a simplistic concept of merely positive affective character, yet recent psychological research has revealed the experience of pleasure is far more complicated. This study explored the nature of pleasure evoked by everyday aesthetic objects. A mixture of statistical and qualitative methods was applied in the analysis of the data collected through a semi-structure…

Root damage induced by intraosseous anesthesia'An in vitro investigation

2012

Objectives: The principle of the intraosseous anesthesia (IOA) relies on the perforation of the cortical plate of the bone for direct application of the local anesthetic solution into the underlying cancellous structures. During this procedure, IOA needles might accidentally come in contact with the tooth roots. The aim of the current in vitro study was to examine the consequences of this ‘worst case scenario’ comparing five commercially available IOA systems. Material and Methods: Extracted human roots were randomly perforated using five different IOA systems with a drilling time ≤5s. To simulate normal in vivo conditions, the roots were kept humid during the drilling procedure. Data was s…

Halogenated Anesthetics Determination in Urine by SPME/GC/MS and Urine Levels Relationship Evaluation with Surgical Theatres Contamination

2014

In this work, a new sensitive analytical method has been developed and evaluated for the determination of the most commonly used gaseous anesthetics, desflurane, sevoflurane, and this latter’s hepatic metabolite hexafluoroisopropanol (HFIP) in the urine. In addition, an evaluation of anesthetics exposition on the urine levels of a small population of surgical operators has been performed and results are briefly discussed.

Current state of dynamic surgery. A literature review.

2021

Background Recently, dental implant technology has been widely used for oral reconstruction. Dental implants are the treatment of choice for those patients with dental absences. An optimal implant placement is based on the prosthetic driven concept in order to achieve an aesthetic and functional restoration with a long-term prognosis. There are two types of guided implant surgery that are described in the literature: Static Guided Surgery (SGS) and Dynamic Guided Surgery (DGS). The aim of this study is to be aware of the current state of dynamic surgery and compare in the literature the discrepancies between planning and placement of dental implants. Material and Methods The study consists …

Management of incomplete regional anaesthesia in Germany: results of a nation-wide survey.

2007

Background:  Regional anaesthesia (RA) provides well-defined benefits with known attendant risks. However, incomplete blockade may introduce unanticipated risks depending on the compensatory measures employed. Until now, no data were available characterizing the pattern of response of German anaesthesiologists in this situation. This study analyses interventions in response to incomplete RA in a nation-wide setting. Methods:  A questionnaire was sent to every German anaesthesia department (n= 1381). Questions focused on interventions coping with an incomplete RA and differentiated between a pre- and a peri-surgical setting and measures to face pain outside the surgical field. If systemic su…

Therapeutic use of hyaluronic acid fillers in the treatment of corticosteroid-induced skin and subcutaneous atrophy

2016

Corticosteroid injection–related tissue atrophy might cause permanent skin and soft tissue deformities1 due to several factors, most importantly fibroblast inhibition and decreased Type I collagen synthesis. Correction of these deformities is challenging and is mostly based on volume replacement with lipofilling or other methods. Clinical observations and research have shown that injection of stabilized hyaluronic acid (HA) induces collagen synthesis, partially restoring dermal matrix components, and eventually producing a permanent effect.2–5 Based on these data, we hypothesize that HA injections might successfully treat atrophic tissue changes caused by corticosteroid injection. We descri…

Surgical sphincter saving approach and topical nifedipine for chronic anal fissure with hypertonic internal anal sphincter

2020

PURPOSE The role of augmented internal anal sphincter (IAS) tone in the genesis of posterior chronic anal fissure (CAPF) is still unknown. Lateral internal sphincterotomy is the most employed surgical procedure, nevertheless it is burdened by high risk post-operative anal incontinence. The aim of our study is to evaluate results of sphincter saving procedure with post-operative pharmacological sphincterotomy for patients affected by CAPF with IAS hypertonia. Methods: We enrolled 30 patients, undergone fissurectomy and anoplasty with V-Y cutaneous flap advancement; all patients received topical administration of nifedipine 0.3% and lidocaine 1.5% ointment-based therapy before and for 15 days…

Topical Airway Anesthesia for Awake-endoscopic Intubation Using the Spray-as-you-go Technique with High Oxygen Flow

2017

A patient's willingness to cooperate is an absolute precondition for successful awake intubation of the trachea. Whilst drug-sedation of patients can jeopardize their spontaneous breathing, topical anesthesia of the airway is a popular technique. The spray-as-you-go technique represents one of the simplest opportunities to anesthetize the airway mucosa. The application of local anesthetic through the working channel of the flexible endoscope is a widespread practice for anesthetists as well as pulmonologists. There is neither need for additional devices nor special training as a pre-requisite to perform this technique. However, a known clinical problem is the coughing and gagging reflex tha…
