Abstract
Staphylococcus pseudintermedius is an emergent zoonotic agent associated with multidrug resistance (MDR). This work aimed to describe the antibacterial activity of four essential oils (EOs) and silver nanoparticles (AgNPs) against 15 S. pseudintermedius strains isolated from pyoderma. The four EOs, namely Rosmarinus officinalis (RO), Juniperus communis (GI), Citrus sinensis (AR), and Abies alba (AB), and AgNPs were used alone and in combination to determine the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). All strains were MDR and methicillin-resistant. Among the antibiotic cohort, only rifampicin, doxycycline, and amikacin were effective. EOs' chemical analysis revealed 124 compounds belonging to various chemical classes. Of them, 35 were found in AR, 75 in AB, 77 in GI, and 57 in RO. The monoterpenic fraction prevailed over the sesquiterpenic in all EOs. When EOs were tested alone, AB showed the lowest MIC followed by GI, AR, and RO (with values ranging from 1:128 to 1:2048). MBC increased in the following order: AB, AR, GI, and RO (with values ranging from 1:512 to 1:2048). MIC and MBC values for AgNPs were 10.74 mg/L ± 4.23 and 261.05 mg/L ± 172.74. In conclusion, EOs and AgNPs could limit the use of antibiotics or improve the efficacy of conventional therapies.

Abstract
BACKGROUND Lifetime elongation of the silicone voice rubber prostheses by inhibition of biofilm formation is a primary objective in voice restoration of laryngectomized patients. This systematic review sought to explore the existing strategies in this direction. MATERIALS We conducted a systematic search of both in vitro and in vivo literature published in PubMed, Scopus, and Cochrane Central Register of Controlled Trials, until December 31, 2022, for published and unpublished trials assessing the strategies for inhibiting biofilm formation on silicone rubber voice prostheses, and appraised quality assessment with the modified Consolidated Standards of Reporting Trials tool. We analyzed the infection prevention capacity of the included antibacterial and antifungal agents. RESULTS The qualitative synthesis showed that both surface modification methods and prophylactic treatment of silicone rubber voice prostheses present adequate antibiofilm activity. Of note, the majority of the suggested prosthetic surfaces were not chronically exposed to both human fluids and biofilm-forming microorganisms. CONCLUSION Various experimental methods provide promising antibiofilm activity and, thus, possible lifespan elongation of silicone rubber voice prostheses.

Abstract
Early failure of silicone voice prostheses resulting from fungal colonization and biofilm formation poses a major concern in modern ear nose throat surgery. Therefore, developing new infection prevention techniques to prolong those implants' survivorship is crucial. We designed an in vitro laboratory study to include nanomaterial-enhanced polymer coating with a plasma spraying technique against Candida albicans growth to address this issue. The anti-biofilm effects of high- and low-dose Al2O3 nanowire and TiO2 nanoparticle coatings were studied either alone or in conjunction with each other using checkerboard testing. It was demonstrated that both nanomaterials were capable of preventing fungal biofilm formation regardless of the anti-fungal agent concentration (median absorbance for high-dose Al2O3-enhanced polymer coating was 0.176 [IQR = 0.207] versus control absorbance of 0.805 [IQR = 0.381], p = 0.003 [98% biofilm reduction]; median absorbance for high-dose TiO2-enhanced polymer coating was 0.186 [IQR = 0.024] versus control absorbance of 0.766 [IQR = 0.458], p < 0.001 [93% biofilm reduction]). Furthermore, synergy was revealed when the Bliss model was applied. According to the findings of this work, it seems that simultaneous consideration of Al2O3 and TiO2 could further increase the existing antibiofilm potential of these nanomaterials and decrease the likelihood of localized toxicity.

Abstract
Osteomyelitis is an infection of the bone characterized by progressive inflammatory destruction and apposition of new bone that can spread via the hematogenous route (hematogenous osteomyelitis (HO)), contiguous spread (contiguous osteomyelitis (CO)), and direct inoculation (osteomyelitis associated with peripheral vascular insufficiency (PVI)). Given the significant financial burden posed by osteomyelitis patient management, the development of new preventive and treatment methods is warranted. To achieve this objective, implementing animal models (AMs) of infection such as rats, mice, rabbits, avians, dogs, sheep, goats, and pigs might be of the essence. This review provides a literature analysis of the AMs developed and used to study osteomyelitis. Historical relevance and clinical applicability were taken into account to choose the best AMs, and some study methods are briefly described. Furthermore, the most significant strengths and limitations of each species as AM are discussed, as no single model incorporates all features of osteomyelitis. HO’s clinical manifestation results in extreme variability between patients due to multiple variables (e.g., age, sex, route of infection, anatomical location, and concomitant diseases) that could alter clinical studies. However, these variables can be controlled and tested through different animal models.

Abstract
It is an undeniable fact that systematic reviews play a crucial role in informing clinical practice; however, conventional head-to-head meta-analyses do have limitations. In particular, studies can only be compared in a pair-wise fashion, and conclusions can only be drawn in the light of direct evidence. In contrast, network meta-analyses can not only compare multiple interventions but also utilize indirect evidence which increases their precision. On top of that, they can also rank competing interventions. In this mini-review, we have aimed to elaborate on the principles and techniques governing network meta-analyses to achieve a methodologically sound synthesis, thus enabling safe conclusions to be drawn in clinical practice. We have emphasized the prerequisites of a well-conducted Network Meta-Analysis (NMA), the value of selecting appropriate outcomes according to guidelines for transparent reporting, and the clarity achieved via sophisticated graphical tools. What is more, we have addressed the importance of incorporating the level of evidence into the results and interpreting the findings according to validated appraisal systems (i.e., the Grade of Recommendations, Assessment, Development, and Evaluation system - GRADE). Lastly, we have addressed the possibility of planning future research via NMAs. Thus, we can conclude that NMAs could be of great value to clinical practice.

Abstract
OBJECTIVES Peritonsillar abscess is a common complication of acute tonsillitis. However, no consensus has been reached yet on the optimal treatment of this condition. Therefore, this study aimed to compare clinical outcomes of immediate and interval abscess tonsillectomy. METHODS The databases of PubMed, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for completed studies published until the 1st of November 2021. Comparative studies assessing intraoperative and postoperative outcomes of immediate and interval abscess tonsillectomy were considered, with the primary outcome being postoperative hemorrhage. Operative time, intraoperative blood loss, postoperative pain, and duration of hospital stay were classed as secondary outcomes. A random-effects pairwise meta-analysis of both randomized and non-randomized trials was conducted. Subgroup analysis linked to the randomization of trials was executed. Quality assessment was performed, utilizing the Cochrane risk of bias tool and ROBINS-I tool for randomized and non-randomized trials, respectively. RESULTS Data from 265 cases stemming from six trials were pooled together. For postoperative bleeding rates, no statistically significant difference between immediate and interval tonsillectomy was detected (OR = 1.26; 95% CI 0.27, 5.86; p = 0.77). By contrast, longer hospital stay was observed for patients subjected to interval tonsillectomy (SMD = - 0.78; CI - 1.39 to- 0.17; p = 0.01). For operative time and intraoperative blood loss, no statistically significant difference was noticed between immediate and interval tonsillectomy (SMD = 1.10; 95% CI - 0.13, 2.33; p = 0.08; and SMD = 0.04; 95% CI - 0.49, 0.57; p = 0.88; respectively). CONCLUSIONS This study shows that quinsy tonsillectomy appears to be a safe method, providing full abscess drainage and instant relief of the symptoms. Moreover, quinsy tonsillectomy was not associated with a statistically higher postoperative hemorrhage incidence rate than immediate tonsillectomy.

Abstract
INTRODUCTION Biofilm formation on voice prostheses is the primary reason for their premature implant dysfunction. Multiple strategies have been proposed over the last decades to achieve inhibition of biofilm formation on these devices. The purpose of this study was to assess the results of the available in vitro biofilm inhibition modalities on silicone rubber voice prostheses. METHODS We conducted a systematic search in PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases up to February 29, 2020. A total of 33 in vitro laboratory studies investigating the efficacy of different coating methods against Candida, Staphylococcus, Streptococcus, Lactobacilli, and Rothia biofilm growth on silicone rubber medical devices were included. Subgroup analysis linked to the type of prevention modality was carried out, and quality assessment was performed with the use of the modified CONSORT tool. RESULTS Data from 33 studies were included in qualitative analysis, of which 12 qualified for quantitative analysis. For yeast biofilm formation assessment, there was a statistically significant difference in favor of the intervention group (standardized mean difference [SMD] = -1.20; 95% confidence interval [CI] [-1.73, -0.66]; p < 0.0001). Subgroup analysis showed that combined methods (active and passive surface modification) are the most effective for biofilm inhibition in yeast (SMD = -2.53; 95% CI [-4.02, -1.03]; p = 0.00001). No statistically significant differences between intervention and control groups were shown for bacterial biofilm inhibition (SMD = -0.09; 95% CI [-0.68, 0.46]; p = 0.65), and the results from the subgroup analysis found no notable differences between the surface modification methods. After analyzing data on polymicrobial biofilms, a statistically significant difference in favor of prevention methods in comparison with the control group was detected (SMD = -2.59; 95% CI [-7.48, 2.31]; p = 0.30). CONCLUSIONS The meta-analysis on biofilm inhibition demonstrated significant differences in favor of yeast biofilm inhibition compared to bacteria. A stronger inhibition with the application of passive or combined active and passive surface modification techniques was reported.

Abstract
Fibromas are benign tumors of connective tissue common in the oral cavity but rare on hard palate. This paper reports on an asymptomatic, slowly growing mass on the hard palate of a 90-year-old lady, with a reported use of denture for two decades. The patient presented with a 2.2cm, smooth-surfaced, well-circumscribed nodule attached with a stalk to the palatal mucosa. After excision, the histopathological examination revealed a mass of fibrous connective tissue, covered by stratified squamous epithelium with focal low-medium grade hyperplasia and hyperkeratosis. These findings were consistent with irritation fibroma of hard palate, a rare entity, which should be considered as a possible diagnosis for tumors of the area by every physician.

Abstract
INTRODUCTION Osteotomy of nasal bones in rhinoplasty is associated with postsurgical morbidities. Recent evidence has suggested that a surgical method applying piezoelectric ultrasound waves for nasal osteotomies in rhinoplasty reduces soft tissue damage and causes less postsurgical morbidities compared to conventional methods. The purpose of this study is to compare clinical outcomes of piezoelectric and conventional lateral nasal osteotomies in rhinoplasty. METHODS We searched PubMed, CENTRAL, and Web of Science up to 17 August 2019 for studies comparing postoperative outcomes of piezoelectric and conventional lateral osteotomies in rhinoplasty. We included studies comparing results of patients subjected to piezoelectric or conventional lateral nasal osteotomies in rhinoplasty. For outcomes, we considered postoperative pain, eyelid edema, periorbital ecchymosis, and intraoperative mucosal injury. RESULTS For eyelid edema, a statistically significant difference in favor of piezoelectric osteotomy was documented within the first 3 postoperative days (standardized mean difference [SMD] = -0.65; 95% CI = -1.18, -0.12, p = 0.02; I2 = 69%) and on postoperative day 7 (SMD = -0.69; 95% CI = -1.47, -0.09; p = 0.08; I2 = 85%). This was also the case for periorbital ecchymosis within the first 3 postoperative days (SMD = -0.85; 95% CI = -1.42, -0.28; p = 0.004; I2 = 72%) and on postoperative day 7 (SMD = -0.52; 95% CI = -0.79, -0.24; p = 0.0003; I2 = 71%). Intraoperative mucosal injury (OR = 0.06; 95% CI = 0.01, 0.53; p = 0.01; Ι2 = 0%) and postoperative pain (SMD = -0.99; 95% CI = -1.78, -0.11; p = 0.01; I2 = 49%) were also statistically lower during piezoelectric osteotomies. CONCLUSIONS This study shows that lateral piezoelectric osteotomy in rhinoplasty decreases postoperative pain, edema, ecchymosis, and intraoperative mucosa injuries compared to the conventional osteotomy technique with a chisel. Piezoelectric osteotomies are especially associated with less postoperative edema and ecchymosis in osteotomies not executed under direct vision.

Abstract
OBJECTIVES To compare the efficacy of autologous whole blood with that of corticosteroid injections on epicondylopathy and plantar fasciopathy. DESIGN Systematic review and meta-analysis. METHODS The databases of PubMed, Web of Science, CENTRAL, and Scopus were searched up to 6th May 2015. Randomized trials comparing the effects of autologous whole blood and corticosteroid injections on epicondylopathy or plantar fasciopathy were included. Trials exploring the efficacy of platelet-rich plasma were excluded. The primary outcome was pain relief. The secondary outcome included the assessment of composite outcomes. All outcomes were assessed at 2-6 (short-term) weeks, 8-13 (intermediate-term) weeks and 24-26 (medium-term) weeks. Quality assessment was performed with the Cochrane risk of bias tool. RESULTS Nine trials were included. For pain relief, there was a statistically significant difference in favour of corticosteroids in the short term (SMD 0.52; 95%CIs 0.18 to 0.86; I2 = 53%; p < 0.01). A statistically significant difference in favour of autologous whole blood was indicated in the medium-term assessment of pain relief on epicondylopathy. CONCLUSIONS Corticosteroids were marginally superior to autologous whole blood in relieving pain on plantar fasciopathy at 2-6 weeks. Autologous whole blood provided significant clinical relief on epicondylopathy at 8-24 weeks. Conclusions were limited by the risk of bias.

Abstract
The aim of this study is to investigate whether the electromagnetic fields associated with mobile phones and/or laptops interfere with blood cell counts of hematology analyzers. Random blood samples were analyzed on an Aperture Impedance hematology analyzer. The analysis was performed in four ways: (A) without the presence of any mobile phone or portable computer in use, (B) with mobile phones in use (B1: one mobile, B4: four mobiles), (C) with portable computers (laptops) in use (C1: one laptop, C3: three laptops), and (D) with four mobile phones and three laptops in use simultaneously. The results obtained demonstrated a statistically significant decrease in neutrophil, erythrocyte, and platelet count and an increase in lymphocyte count, mean corpuscular volume, and red blood cell distribution width, notably in the B4 group. Despite this statistical significance, in clinical practice, only the red blood cell reduction could be taken into account, as the mean difference between the A and B4 group was 60,000 cells/µL. In group D, the analyzer gave odd results after 11 measurements and finally stopped working. The combined and multiple use of mobile phones and computers affects the function of hematology analyzers, leading to false results. Consequently, the use of such electronic devices must be avoided.
