Delaying surgery for patients with a previous SARS-CoV-2 infection
2020
With at least 28 elective million operations delayed during the first three months of the COVID-19 pandemic, the number of patients who will require surgery after a previous SARS-CoV-2 infection is likely to increase rapidly1. Operating on patients with an active perioperative SARS-CoV-2 infection is now known to carry a very high pulmonary complication and mortality rate2. Urgent information is needed to guide whether postponing surgery in patients with a previous SARS-CoV-2 infection leads to a clinical benefit, and the optimal length of delay.
Botulinum toxin in preparation of oral cavity for microsurgical reconstruction.
2010
CONCLUSIONS: Infiltration of botulinum toxin in the major salivary glands allows a temporary reduction of salivation that begins 8 days afterwards and returns to normal within 2 months. The inhibition of salivary secretion, carried out before the oral cavity reconstructive surgery, could allow a reduction of the incidence of oro-cutaneous fistulas and local complications. OBJECTIVES: Saliva stagnation is a risk factor for patients who have to undergo reconstructive microsurgery of the oral cavity, because of fistula formation and local complications in the oral cavity. The authors suggest infiltration of botulinum toxin in the major salivary glands to reduce salivation temporarily during th…
Safety Evaluation of Food contact paper and board using Chemical Tests and in vitro Bioassays-The role of known and unknown substances
2010
International audience; In vitro toxicological tests has have been proposed as an approach to complement the chemical safety assessment of food contact materials, particularly those with a complex or unknown chemical composition such as paper and board. An EU 5th framework program project “BIOSAFEPAPER – Application of bioassays for safety assessment of paper and board for food contact” specially focused on the application of biotests to paper and board. The project included both chemical characterization and toxicological testing of a representative number of paper and board extracts prepared according to the proposed end use (wet, fatty and dry food contact). Among the concerns addressed …
Oncological Outcomes of Primary vs. Salvage OPHL Type II: A Systematic Review
2022
Background: Open partial horizontal laryngectomy type II (OPHL type II) has two main aims: oncological radicality and laryngeal preservation. The aim of this review is to define and emphasize the oncological efficacy of OPHL type II, both as primary and salvage surgery, by analyzing the latest literature. Methods: The research was carried out on Pubmed, Scopus and Web of Science databases, by using strict keywords. Oncological outcomes were evaluated by the following parameters: overall survival, disease-specific survival, disease-free survival, local control, laryngeal preservation, local recurrence. Results: The review included 19 articles divided into three groups: (1) primary OPHL type …
Biologic response of inguinal hernia prosthetics: a comparative study of conventional static meshes versus 3D dynamic implants.
2015
Despite improvements in prosthetics and surgical techniques, the rate of complications following inguinal hernia repair remains high. Among these, discomfort and chronic pain have become a source of increasing concern among surgeons. Poor quality of tissue ingrowth, such as thin scar plates or shrinking scars-typical results with conventional static implants and plugs-may contribute to these adverse events. Recently, a new type of 3D dynamically responsive implant was introduced to the market. This device, designed to be placed fixation-free, seems to induce ingrowth of viable and structured tissue instead of regressive fibrotic scarring. To elucidate the differences in biologic response be…
Inflammation and sarcopenia: A systematic review and meta-analysis
2017
Inflammatory cytokines have been shown to prompt muscle wasting, ultimately stimulating protein catabolism and suppressing muscle synthesis. However, the possible association between inflammatory parameters and sarcopenia is poorly understood. We therefore aimed to summarize the current evidence about this topic with a meta-analysis of studies reporting serum inflammatory parameters in patients with sarcopenia vs. people without sarcopenia (controls). An electronic PubMed and Scopus search through to 09/01/2016 and meta-analysis of cross-sectional studies comparing serum levels of inflammatory cytokines between patients with sarcopenia and controls was made, calculating random-effects stand…
Universal newborn hearing screening in the Italian Region of Sicily in 2018
2021
We have clarified the role of Universal Neonatal Hearing Screening (UNHS) for both early diagnosis and rapid treatment in order to improve the prognosis of the deaf child and reduce patient management costs. Although in Sicily UNHS has been progressively implemented, there is scarce data in the literature on this matter. Therefore, the main objective was to collect in the year 2018 the following data: number of newborns screened for hearing loss, number of infants "referred" to transiently evoked otoacoustic emissions (TEOAE), number of infants with pathologic auditory brainstem response (ABR) and number of infants affected by permanent hearing loss.UNHS monitoring was conducted through the…
An adaptive multimeme algorithm for designing HIV multidrug therapies.
2007
This paper proposes a period representation for modeling the multidrug HIV therapies and an Adaptive Multimeme Algorithm (AMmA) for designing the optimal therapy. The period representation offers benefits in terms of flexibility and reduction in dimensionality compared to the binary representation. The AMmA is a memetic algorithm which employs a list of three local searchers adaptively activated by an evolutionary framework. These local searchers, having different features according to the exploration logic and the pivot rule, have the role of exploring the decision space from different and complementary perspectives and, thus, assisting the standard evolutionary operators in the optimizati…

Laparoscopic surgical management of localized recurrent ovarian cancer: a single-institution experience
2014
Background: Optimally, secondary cytoreduction is acknowledged as a valid option in terms of oncologic outcome for patients with platinum-sensitive recurrent ovarian cancer. In cases of localized relapse, a laparoscopic approach has been attempted at various institutions, but studies on its role for this subset of patients still are limited. This report describes the authors' experience using laparoscopic secondary cytoreduction for patients with localized recurrent ovarian cancer. The results from a retrospective analysis of a prospective case series are reported. Methods: Between October 2011 and May 2013, 29 patients with localized recurrent ovarian cancer were selected for a laparoscopi…
