Abstract
PURPOSE Head and neck sarcomas (HNS) constitute a rare and heterogeneous cancer entity. Management remains a challenge due their rarity and different biological behaviour among tens of subtypes. This systematic review aimed to describe HNS global frequency and distribution in adulthood. METHODS A systematic review was performed using PICOTS search strategies for qualitative question and it was written in accordance with PRISMA 2020 Statement. 70,653 publications were identified, and 15 variables were evaluated for a total of 2428 patients. RESULTS We identified 47 studies from 21 different countries from 5 different continents. Most of studies (83.3%) were performed in single institutions and America and Asia overruled for number of papers included (21 and 10, respectivelly). Osteosarcoma was more frequent, followed by chondrosarcoma, angiosarcoma and malignant fibrous histiocytoma. Early stage accounted for almost 80% of cases; advanced stage prevailed in developing countries. 1783 patients (90.1%) underwent surgery and 780 (39.4%) had adjuvant therapy. 50.8% of patients experienced tumour recurrence and the lowest mortality rate was reported in Europe (29.9%). CONCLUSIONS HNS holds a relative poor prognosis possibly explained by the heterogeneity of the disease. Treatment of HNS has shown to be highly diverse among different countries, underlining the importance of uniformed treatment guidelines to achieve better patient management and to improve survival outcomes.

Abstract
Objective The primary focus of this study was to analyze the adoption of ChatGPT among Ear, Nose, and Throat (ENT) trainees, encompassing its role in scientific research and personal study. We examined in which year ENT trainees become involved in clinical research and how many scientific investigations they have been engaged in. Methods An online survey was distributed to ENT residents employed in Italian University Hospitals. Results Out of 609 Italian ENT trainees, 181 (29.7%) responded to the survey. Among these, 67.4% were familiar with ChatGPT, and 18.9% of them used artificial intelligence as a tool for research and study. In all, 32.6% were not familiar with ChatGPT and its functions. Within our sample, there was an increasing trend of participation by ENT trainees in scientific publications throughout their training. Conclusions ChatGPT remains relatively unfamiliar and underutilised in Italy, even though it could be a valuable and efficient tool for ENT trainees, providing quick access for study and research through both personal computers and smartphones.

Abstract
Fibrinogen and homocysteine (HCY) are molecules known to play a role in vascular homeostasis, and their blood levels are often elevated in patients with metabolic syndrome. Recent evidence suggests that sudden sensorineural hearing loss (SSHL) may have a vascular origin. This has led many authors to advocate that fibrinogen, homocysteine, and metabolic syndrome (MetS) may play a direct role in SSHL. The aim of this brief review is to examine the role and influence of these molecules and MetS on the mechanisms of SSHL. Elevated fibrinogen levels have been associated with a worse prognosis in SSHL, possibly due to increased blood viscosity and decreased blood flow. Similarly, HCY has been associated with vascular damage, particularly in hyperhomocysteinemia, although the exact association with SSHL remains controversial. MetS has been demonstrated to function both as a causative factor and as a contributor to poorer recovery in cases of SSHL. However, although some studies suggest a possible role for these biomarkers and MetS in the prognosis and treatment of SSHL, specific therapeutic and preventive strategies based solely on these factors have yet to be developed. Given their potential role in prognosis and treatment and the global epidemic of metabolic syndrome, this issue needs to be analyzed comprehensively. Thus, further quality studies need to be conducted, even though it is difficult to determine the actual impact of MetS on the development of SSHL, as it is a multifactorial disease affecting multiple organs.

Abstract
Oxidized cellulose is a hemostatic agent currently used in surgery. Foreign body reactions have been described after its use. This paper describes a foreign body reaction caused by oxidized cellulose in a young woman who underwent thyroid surgery. A patient underwent two thyroid surgeries for treatment of papillary carcinoma. Five years after the last surgery, an asymptomatic mass was detected with a routine ultrasound in the left thyroid cavity. After surgical removal, the mass turned out to be a foreign body granuloma based on oxidized cellulose sheets used in the previous surgery. The patient was discharged from the hospital without complications. The follow-up period was uneventful. Oxidized cellulose is a useful tool in surgery to control and prevent intra and post-operative bleeding. Even if it is a biodegradable material, sometimes it persists in the human body causing foreign body reactions that can be misdiagnosed.

Abstract
Laryngeal cancer is a very common tumor in the upper aero-digestive tract. Understanding its biological mechanisms has garnered significant interest in recent years. The development of laryngeal squamous cell carcinoma (LSCC) follows a multistep process starting from precursor lesions in the epithelium. Various risk factors have been associated with laryngeal tumors, including smoking, alcohol consumption, opium use, as well as infections with HPV and EBV viruses, among others. Cancer development involves multiple steps, and genetic alterations play a crucial role. Tumor suppressor genes can be inactivated, and proto-oncogenes may become activated through mechanisms like deletions, point mutations, promoter methylation, and gene amplification. Epigenetic modifications, driven by miRNAs, have been proven to contribute to LSCC development. Despite advances in molecular medicine, there are still aspects of laryngeal cancer that remain poorly understood, and the underlying biological mechanisms have not been fully elucidated. In this narrative review, we examined the literature to analyze and summarize the main steps of carcinogenesis and the risk factors associated with laryngeal cancer.

Abstract
Optical forces are used to push and aggregate gold nanorods onto several substrates creating surface-enhanced Raman scattering (SERS) active hot spots for Raman-based identification of proteins. By monitoring the increase of the protein SERS signal, we observe different aggregation times for different curvatures of the substrates. The slower aggregation dynamics on curved surfaces is justified by a simple geometrical model. In particular, this technique is used to decorate three-dimensional microstructures and to quickly realize hybrid micro/nanosensors for highly sensitive detection of biological material directly in a liquid environment.

Abstract
Capillary malformations (CMs) and Lymphatic malformations (LMs) are vascular malformations that share a common tendency to cause soft and hard tissue hypertrophy, expressed in the three dimensions of the space. The middle third of the face is the most commonly involved area, with a predominance of the upper lip. To our knowledge, no paper has previously focused on the surgical technique to correct such deformities. We propose and illustrate a surgical protocol, consisting in merging an asymmetric bikini upper lip reduction and a unilateral bull horn resection technique, that allowed to reduce the overall volume of the hypertrophied lip thus restoring lip symmetry. We adopted this technique in 2 patients affected by CMs and 4 patients with LMs, with satisfactory results.

Abstract
For decades, lipid droplets have been considered as the main cellular organelles involved in the fat storage, because of their lipid composition. However, in recent years, some new and totally unexpected roles have been discovered for them: (i) they are active sites for synthesis and storage of inflammatory mediators, and (ii) they are key players in cancer cells and tissues, especially in cancer stem cells. In this review, we summarize the main concepts related to the lipid droplet structure and function and their involvement in inflammatory and cancer processes.

Abstract
Outstanding results have been achieved in the localization of optical electric fields via ultrasmall plasmonic cavities, paving the way to the subdiffractive confinement of local electromagnetic fields. However, due to the intrinsic constraints related to conventional architectures, no comparable squeezing factors have been managed yet for the magnetic counterpart of radiation, practically hindering the detection and manipulation of magneto-optical effects at the nanoscale. Here, we observe a strong magnetic field nanofocusing in the infrared, promoted by the induction of a coil-type Fano resonance. By triggering the coil current via a quadrupole-like plasmonic mode, we straightforwardly boost the enhancement of the infrared magnetic field and perform its efficient squeezing in localized nanovolumes.

Abstract
We describe a new method to generate thin (thickness > 200 nm) and ultrathin (thickness < 200 nm) fluorescent layers to be used for microscope optical characterization. These layers are obtained by ultramicrotomy sectioning of fluorescent acrylic slides. This technique generates sub-resolution sheets with high fluorescence emission and uniform thickness, permitting to determine the z-response of different optical sectioning systems. Compared to the state of the art, the here proposed technique allows shorter and easier manufacturing procedure. Moreover, these fluorescent layers can be employed without protective coverslips, allowing the use of the Sectioned Imaging Property (SIP)-chart characterization method with coverslip-uncorrected objectives, water immersion objectives and micro-endoscopes.

Abstract
The possibility to develop nanosystems with appreciable magnetic response at optical frequencies has been a matter of intense study in the past few years. This aim was strongly hindered by the saturation of the magnetic response of "natural" materials beyond the THz regime. Recently, in order to overcome such limitation, it has been considered to enhance the magnetic fields through the induction of displacement currents triggered by plasmonic resonances. Here we investigate a nanoassembly supporting the hybridization of an electric and magnetic plasmonic mode in Fano resonance conditions. Taking advantage of the enhancement properties owned by such interferential resonance, we have been able to generate an intense and localized magnetic hot-spot in the near-infrared spectral region.

Abstract
The use of individual multimode optical fibers in endoscopy applications has the potential to provide highly miniaturized and noninvasive probes for microscopy and optical micromanipulation. A few different strategies have been proposed recently, but they all suffer from intrinsically low resolution related to the low numerical aperture of multimode fibers. Here, we show that two-photon polymerization allows for direct fabrication of micro-optics components on the fiber end, resulting in an increase of the numerical aperture to a value that is close to 1. Coupling light into the fiber through a spatial light modulator, we were able to optically scan a submicrometer spot (300 nm FWHM) over an extended region, facing the opposite fiber end. Fluorescence imaging with improved resolution is also demonstrated.

Abstract
We report on the possibility of realizing adiabatic surface plasmon polaritons compression on metallic conical tips built-in on AFM cantilevers by means of different approaches. The problem is faced considering the role of the source, when linear and radial polarizations are assumed, associated to different fabrication schemes. Nano-patterned devices properly combined with metallic conical tips can affect the adiabatic characteristic of the surface electric field. The results are analyzed in terms of tradeoff between fabrication difficulties and device performances. Suggestions on the best possible scheme are provided.

Abstract
The application of new methods and techniques to fields such as biology and medicine is becoming more and more demanding since the request of detailed information down to single molecules is a scientific necessity and a technical realistic possibility. In this effort a key role is played by emerging fabrication techniques. One of the hardest challenges is to incorporate the third dimension in the design and fabrication of novel devices. Significantly, this means that conventional nano-fabrication methods, intrinsically useful for planar structuring, have to be substituted or complemented with new approaches. In this paper we show how emerging techniques can be used for 3D structuring of noble metals down to nanoscale. In particular, the paper deals with electroless deposition of silver, ion and electron beam induced deposition, focused ion beam milling, and two-photon lithography. We exploited these techniques to fabricate different plasmonics nanolenses, nanoprobes and novel beads for optical tweezers. In the future these devices will be used for the manipulation and chemical investigation of single cells with sensitivity down to a few molecules in label free conditions and native environment. Although this paper is only devoted to nanofabrication, we foresee that the fields of biology and medicine will directly gain substantial advantages from this approach.

Abstract
Multitasking nanoparticles are gaining great attention for smart drug delivery systems. The exploration of the nano-scale opens new concrete opportunities for revealing new properties and undiscovered cell-particle interactions. Here we present a biodegradable nanoporous silicon nanoparticle that can be successfully employed for in vivo targeted drug delivery and sustained release. The bare nanoporous nanocarriers can be accurately designed and fabricated with an effective control of porosity, surface chemistry and particle size, up to a few nm. The proposed nanoparticles exhibit several remarkable features including high payload, biodegradability, no toxicity, and multiple loading in water without the need of additional chemical reagents at room temperature. The targeting strategy is based on phage display technology that was successfully used to discover cell surface binding peptide for murine B lymphoma A20 cell line. The peptide used in combination with the nanoporous nanoparticles allows an efficient in vivo targeting, a sustained release and a sensible therapeutic effect.

Abstract
We propose an experimental technique that allows for a complete characterization of the amplitude and phase of optical pulses in space and time. By the combination of a spatially resolved spectral measurement in the near and far fields and a frequency-resolved optical gating measurement, the electric field of the pulse is obtained through a fast, error-reduction algorithm.

Abstract
We present the numerical modelling of a novel all-fiber optical tweezers, whose efficacy has been recently demonstrated. The device, realized by properly shaping the end-face of a fiber bundle, exploits total internal reflection to enhance the trapping efficiency. In order to allow the optimization of the performance, the trapping efficiency is evaluated as a function of different geometrical parameters of the structure. Given the peculiar spatial and angular distribution of the optical field, a new figure of merit is adopted to assess tweezers performance.
