Background : To investigate whether cognitive impairment in elderly patients could correlate with the severity of swallowing disorders detectable through the endoscopic fiber optic evaluation. Methods : Elderly patients (≥65 years) performing a swallowing evaluation were included and divided according to the Dysphagia outcome and severity scale (DOSS). Neurological evaluation and Mini-Mental test examination (MMET) were administered to detect cognitive impairment. Results : Significantly worse swallowing function was reported in the cognitive impairment group than the control one (40% vs 19%; P =.001). A different significant distribution of swallowing performance was detected according to the patient's MMET score (P <.001; P <.001; P =.01). At the ANOVA test among dependent variables assessed, only age>65 and MMET<10 were significantly correlated with swallowing function (F = 3.862, P =.028; F = 17.49, P =.000). Conclusions: The elderly patient has an increased risk for unrecognized swallowing disorders, with a prevalence of mild to moderate forms. Assessment of cognitive performance could facilitate the identification of swallowing disorders by providing a higher level of suspicion for silent aspiration in subjects with poor MMET scores.

Background: Facial synkinesis (FS) is a distressing sequela of facial palsy (FP) characterized by involuntary, simultaneous movements of facial muscles occurring during voluntary facial expressions. Treatment of synkinesis is challenging, and preventive methods are needed. Aim: This study evaluated the efficacy of physical facial nerve rehabilitation (PFNR) therapy alone vs. PNFR with eyelid surgery to correct lagophthalmos and prevent the onset of synkinesis. Methods: Twenty five outpatients were randomized to receive either PFNR alone (neuromuscular retraining and Kabat proprioceptive neuromuscular facilitation) or PNFR and early (90 days after FP onset) eyelid surgery (involving a conservative oculoplastic correction for lagophthalmos with epiphora or ectropion). Comprehensive otolaryngological assessments and Magnetic Resonance Imaging (MRI) were conducted. Synkinesis progression was measured using Another Disease Scale (ADS) at baseline, 3-, 6-, 12-, and 24-months post-treatment. The data were analyzed with ANOVA, τ-test, Chi-Square analyses. Results: Patients undergoing eyelid surgery with PFNR showed faster (p < 0.001) and better recovery of facial movements (p < 0.05) than patients receiving PFNR alone comparing T0 and T12 (p < 0.0001). No synkinesis were observed in the PFNR plus surgery group while 37% of patients in PFNR alone had synkinesis (p = 0.03). At 24months, none of the patients in the surgery group presented synkinesis. Conclusion: Combining early surgical treatment of paralytic lagophthalmos or epiphora with PFNR accelerated functional recovery and reduced synkinesis in patients with FP compared to facial rehabilitation alone. Further investigations in larger populations with long-term follow-up are needed. [ABSTRACT FROM AUTHOR]

Background: Patients treated with definitive radiotherapy for nasopharyngeal carcinoma (NPC) develop severe dysphagia, affecting their quality of life. Traditional prognosis biomarkers are insufficient, leading to a search for new predictors like neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Methods: We retrospectively enrolled 44 NPC patients who underwent definitive radiotherapy between 2010 and 2018. EQUATOR and STROBE network guidelines were adopted. Pre-treatment evaluations were conducted, and post-treatment oropharyngeal dysphagia was assessed using the Sydney Swallow Questionnaire (SSQ) and FEES, then assigning a Dysphagia Outcome and Severity Scale (DOSS) level. Patients were divided based on NLR and PLR cut-offs, comparing subjective dysphagia (SSQ) scores and DOSS results at baseline and after a 5-year follow-up. Multiple linear regression was used for analysis. Results: At baseline, the mean NLR was 2.52 ± 1.10, and the PLR was 208.40 ± 94.35. Multivariate analysis indicated NLR and PLR as significant predictors of DOSS outcomes (p < 0.001). Conclusions: Baseline inflammation markers, such as NLR and PLR, may be used to predict dysphagia severity in NPC patients undergoing definitive radiotherapy. These markers could help identify patients at higher risk for severe dysphagia and implement tailored therapeutic and rehabilitative strategies to improve their quality of life. Further studies with larger cohorts are needed to confirm these findings and explore additional prognostic factors for dysphagia outcomes in NPC patients. [ABSTRACT FROM AUTHOR]

Objectives: Saccharin test (ST) is a convenient method to assess the efficiency of mucociliary clearance, the primary defense mechanism of the upper airways' tract. The study objectives are to: (1) substantiate its short- (3 days) and long-term (30 days) repeatability; (2) assess its tolerability; (3) conduct a systematic literature review and to compare our results with the existing evidence. Methods: Twenty-nine healthy subjects were enrolled in an observational prospective study to perform an ST on three separate visits (at baseline; at follow-up visits at day 3 and at day 30). Transit times were recorded and self-reported nasal and general symptoms noted. A systematic review of the literature was conducted to compare our results with the existing literature. Results: The mean values (±SD) of ST transit time (STTT) were 7.085 (±2.19), 7.788 (±2.11), and 7.790 (±2.06) minutes at baseline, day 3, and day 30, respectively. Significant linear regression analysis was observed between day 3 and baseline (r =.193; P =.019) and day 30 and baseline (r =.182 P =.024). Significant agreement for the intrasession repeatability was observed with an ICC =.354 (P =.001). Outcomes' comparisons between baseline vs day 3 (P =.197) and baseline vs day 30 (P =.173) were not statistically significant. ST was well tolerated. Concordance with existing literature's data and high level of STTT repeatability were confirmed by the qualitative analysis. Conclusion: STTT reproducibility was good both in the short- and long-term. ST tolerability was very good. Our study data are consistent with the existing literature, indicating ST as a sound methodology for detection of early respiratory health changes and for specific regulatory application in respiratory research.

The development of language, memory and intellectual functions is linked to normal hearing and correct sounds interpretation. Hearing loss (HL), especially in its severe form, negatively affects the development of these functions. This prospective study aimed at comparing the Intelligent Quotients (IQ) of children with cochlear implants (CI) with the ones of people wearing hearing aids (HA) after one year of hearing rehabilitation. 21 subjects with severe/profound bilateral hearing loss (deafness) were included in this study. Eleven children with congenital profound HL underwent CI and ten children with moderate to severe HL (congenital and acquired) were rehabilitated by HA. Children's IQs were assessed at enrolment (T0) and 12 months after hearing aids/CI use plus speech therapy. Statistical analyses were performed to analyze the data within and between groups. Comparison of IQs showed no statistically significant differences between CI and HA none at T0 and T1. The subtests showed lower scores in verbal comprehension and process speed index in patients treated with HA when compared to CI. This study showed that auditory rehabilitation can support the normal development of cognitive function in children between six and eight years of age. The use of the correct hearing aids based on the patient's hearing thresholds is important to maximize the rehabilitation outcomes. Due to the small sample size, although stratified for age, our results must be considered preliminary and further analyses on larger samples are needed to confirm our data. [ABSTRACT FROM AUTHOR]

The oral transmission of HPV and, consequently, the risk of oral cancer has increased in the last years. Oral sex has often been implicated among the risk factors for oral HPV infections, however, there is still no consensus on these topics, nor on the relationship between genital and oral HPV infections. The present study aimed to evaluate the coexistence of papilloma virus, at the levels of the oral and genital mucosa, in women with a histologically confirmed HPV lesions (and a positive HPV test) at the genital level and a negative HPV control group. We also evaluated how some risk factors, such as smoking, the number of partners, age, and sexual habits can influence the possible presence of the virus itself in the oropharynx of the same women. In total, 117 unvaccinated women aged between 18 and 52 were enrolled. We found that the prevalence of oral HPV infection was high among the women with concomitant genital HPV infection (22%) compared to the HPV-negative women (0%), and the estimated odds ratio was 17.36 (95% CI: 1.02, 297.04). In none of the women with oral HPV did we find any relevant clinical lesions. The potential risk factors for HPV infections in the oropharynx and genitals were analyzed based on questionnaire responses. A multivariate analysis showed that genital HPV infections were significantly associated with a number of sexual partners > 10 (OR 138.60, 95% CI: 6.04–3181.30, p < 0.001), but the data also referred to having between 3–5 or 6–10 partners as being significant, as were a high level of education (OR 6.24, 95% CI: 1.67–4.23.26 p = 0.003), a frequency of sexual intercourse >10 (OR 91.67 95% CI: 3.20–2623.52, p = 0.004), oral sex (OR 6.16, 95% CI: 1.22–31.19, p = 0.014), and >20 cigarettes/day (OR 6.09 95% CI: 1.21–30.61, p = 0.014). Furthermore, being "separate" and having multiple sexually transmitted diseases were also significantly associated with genital HPV infection. In contrast, oral HPV infections were significantly associated with women aged 36 to 50 years (OR 27.38, 95% CI: 4.37–171.37; p = 0.000202) and oral sex (OR 95.5, 95% CI: 5.13–1782.75, p = 0.001126).Additionally, being separate, being cohabitant, lifetime sexual partners of >10, 3–5 lifetime sexual partners, <20 years of age, >10 sexual intercourse per month, occasional and regular anal sex, >20 cigarettes per day, a history of sexually transmitted disease (herpes and multiple), and having a history of genital warts were significant. Screening and early diagnosis are considered to be practically unfeasible for this category of cancer, given the lack of visible lesions; the 9-valent HPV vaccine remains the only means that could help to successfully counter the growing incidence of oral squamous cell carcinoma.

Autosomal dominant non-syndromic hearing loss (HL) typically occurs when only one dominant allele within the disease gene is sufficient to express the phenotype. Therefore, most patients diagnosed with autosomal dominant non-syndromic HL have a hearing-impaired parent, although de novo mutations should be considered in all cases of negative family history. To date, more than 50 genes and 80 loci have been identified for autosomal dominant non-syndromic HL. DFNA22 (MYO6 gene), DFNA8/12 (TECTA gene), DFNA20/26 (ACTG1 gene), DFNA6/14/38 (WFS1 gene), DFNA15 (POU4F3 gene), DFNA2A (KCNQ4 gene), and DFNA10 (EYA4 gene) are some of the most common forms of autosomal dominant non-syndromic HL. The characteristics of autosomal dominant non-syndromic HL are heterogenous. However, in most cases, HL tends to be bilateral, post-lingual in onset (childhood to early adulthood), high-frequency (sloping audiometric configuration), progressive, and variable in severity (mild to profound degree). DFNA1 (DIAPH1 gene) and DFNA6/14/38 (WFS1 gene) are the most common forms of autosomal dominant non-syndromic HL affecting low frequencies, while DFNA16 (unknown gene) is characterized by fluctuating HL. A long audiological follow-up is of paramount importance to identify hearing threshold deteriorations early and ensure prompt treatment with hearing aids or cochlear implants. [ABSTRACT FROM AUTHOR]

Far-advanced otosclerosis (FAO) refers to severe otosclerosis with scarce auditory functions. The identification of the best method to correctly listen to sound and speech has a large impact on patients' quality of life. We retrospectively analyzed the auditory function of 15 patients affected by FAO who were treated with stapedectomy plus hearing aids independent of the severity of their auditory deficit before surgery. The combination of surgery and hearing aids allowed excellent recovery of the perception of pure tone sounds and speech. Four patients, because of poor auditory thresholds, needed a cochlear implant after stapedectomy. Despite being based on a small sample of patients, our results suggest that stapedotomy plus hearing aids could improve the auditory capacities of patients with FAO independent of their auditory thresholds at T0. The careful selection of patients is fundamental to obtain the best outcomes. [ABSTRACT FROM AUTHOR]

The role of nasal microbiota in contributing to neuroinflammation is gradually emerging. Multiple sclerosis and chronic rhinosinusitis share important clinical and epidemiological similarities, and the hypothetical connection among these two pathological entities should be carefully investigated. This editorial is based on a review of available literature on this topic. The main international databases were searched using the following keywords: neuroinflammation, nasal microbiota, multiple sclerosis, chronic rhino-sinusal disorders, chronic sinusitis. Four fully-consistent articles that investigated nasal microbiota alteration and/or chronic rhinosinusitis presence in subjects affected by multiple sclerosis were identified. Overall, these studies showed a significant connection between nasal microbiota dysbiosis and the presence of multiple sclerosis. New specific studies to analyze the nasal microbiota and its metabolism in patients affected by multiple sclerosis should be performed. In fact, a series of treatments able to change this flora could improve the rhino-sinusal state with consequent reduction of recurrent episodes of neuro-inflammation. [ABSTRACT FROM AUTHOR]

Background: To compare the functional and anatomical results of two different types of grafts in type 1 tympanoplasty (TPL I). Methods: A retrospective comparative bicentric study was conducted on patients treated with TPL I using temporal fascia or tragal cartilage. We evaluated the functional and anatomical results with intergroup and intragroup analyses. Variables predicting long-term success were also evaluated. Results: A total of 142 patients (98 fascia graft vs. 44 cartilage) were initially assessed, with a mean follow-up of 67.1 ± 3.2 months. No significant differences were observed between the two groups on the intergroup analysis of age, gender, ear side, or pre-operative hearing data (all p > 0.05). At the intragroup analysis of auditory outcomes, both groups demonstrated a significant improvement in post-operative air conduction, with greater gain for the fascia group at 6 months follow-up (p < 0.001 for both); however, at long-term follow-up, cartilage demonstrated better stability results (p < 0.001). When comparing the pre-and post-operative air-bone-gap (ABG), both groups showed a significant gain (p < 0.001); the fascia group showed that at 6 months, a greater ABG increase was found, but the difference was not statistically significant (4.9 ± 0.9 dB vs. 5.3 ± 1.2 dB; p = 0.04). On the contrary, the cartilage group at long-term follow-up at 5 years maintained greater outcomes (10 ± 1.6 dB vs. 6.4 ± 2 dB; p < 0.001). Lower age (F = 4.591; p = 0.036) and higher size of perforation (F = 4.820; p = 0.030) were predictors of long-term functional success. Conclusions: The graft material selection should consider several factors influencing the surgical outcome. At long-term follow-up, the use of a cartilage graft could result in more stable audiological outcomes, especially in younger patients or in case of wider perforations. [ABSTRACT FROM AUTHOR]

Absolute indications for the CWD approach include unresectable disease, an unreconstructable posterior canal wall, failure of a first-stage canal wall up approach because of poor eustachian tube function, and inadequate patient follow-up [[25], [30]].

Background: The eligibility criteria for cochlear implantation are constantly evolving, following the continuous progress in technology, knowledge about cochlear implant (CI) fitting, and the possibility to preserve residual hearing. Appropriate attention should be given to asymmetric hearing loss (AHL) and single-side deafness (SSD) subjects. This study aimed to analyze cochlear implant indications and evaluate the longitudinal performance outcomes for patients with different kinds and degrees of sensorineural hearing loss. Methods: A total of 69 adult hearing loss CI recipients were included and divided into four subgroups according to our CI indication criteria. We performed objective and subjective measures, including speech perception analysis in silence and with background noise, comparing the outcomes obtained in the four groups. Results: After cochlear implant surgery, concerning the preimplantation daily listening condition, a significantly improved speech perception score in silence and noise was found in all four groups (p < 0.05 for all). Conclusion: CI could represent an efficient solution for patients with AHL and SSD classes. [ABSTRACT FROM AUTHOR]

Over the last decade, technological growth has developed new devices for more precise surgery based on improved maneuverability, minimally invasive approaches, and magnification of the operating field. In this context, the exoscope has opened a new phase for more accurate and safer microsurgery, improving the perception of the volume of objects and the depth of structures for planning, targeting, and controlling fine movements. The exoscope could be used for middle ear, transcanal, transmastoid, and craniotomy procedures that require two-handed dissection, both to perform both totally VITOM-based techniques and coupled to traditional procedures with an operating microscope or endoscope. In addition, the VITOM 3D system allows the surgeon to work with high-definition images, which is essential in facial nerve surgery or submandibular salivary stone or tear surgery approaches, where magnification plays a fundamental role in surgical success and in reducing operating times. The 3D exoscope approach could also be included in traditional transoral procedures for oropharyngeal carcinoma. The exoscope may provide a relevant approach in teaching surgeons and nurses, allowing adequate training in non-oncological surgical procedures such as a tonsillectomy or lateral pharyngoplasty.

We report on our remote speech therapy experience in post-stroke aphasia. The aim was to test the feasibility and utility of telerehabilitation to support future randomized controlled trials. Post-stroke aphasia is a common and disabling speech disorder, which significantly affects patients' and caregivers' health and quality of life. Due to COVID-19 pandemic, most of the conventional speech therapy approaches had to stop or 'switch' into telerehabilitation procedures to ensure the safety of patients and operators but, concomitantly, the best rehabilitation level possible. Here, we planned a 5-month telespeech therapy programme, twice per week, of a patient with non-fluent aphasia following an intracerebral haemorrhage. Overall, treatment adherence based on the operator's assessments was high, and incomplete adherence for technical problems occurred very rarely. In line with the patient's feedback, acceptability was also positive, since he was constantly motivated during the sessions and the exercises performed autonomously, as confirmed by the speech therapist and caregiver, respectively. Moreover, despite the sequelae from the cerebrovascular event, evident in some writing tests due to the motor deficits in his right arm and the disadvantages typical of all telepractices, more relevant results were achieved during the telerehabilitation period compared to those of the 'face-to-face' therapy before the COVID-19 outbreak. The telespeech therapy performed can be considered successful and the patient was able to return to work. Concluding, we support it as a feasible approach offering patients and their families the opportunity to continue the speech and language rehabilitation pathway, even at the time of pandemic.

(1) Background: This systematic review was designed to analyze adenotonsillectomy’s role in treating behavioural disorders and sleep-related quality of life in pediatric OSAS. (2) Methods: Papers that report pre-operative and post-operative outcomes by using the Epworth sleepiness scale, OSA-18, NEPSY, Conners’ rating scale, BRIEF, PSQ-SRBD, PedsQL and CBCL. We performed a comprehensive review of English papers published during the last 20 years regarding behavioural disorders in OSAS patients and adenotonsillectomy. (3) Results: We included 11 studies reporting behavioral outcomes and sleep related quality of life after surgery. We investigated changes in behavior and cognitive outcomes after AT, and we found significant improvements of the scores post-AT in almost all studies. After comparing the AT group and control group, only one study had no difference that reached significance at one year post-AT. In another study, it did not show any significant improvement in terms of all behavioural and cognitive outcomes. The questionnaires on sleep-related quality of life after AT (PSQ-SRBD or ESS or OSA-18 or KOSA) may improve with positive changes in sleep parameters (AHI, ODI and SpO2). Furthermore, there is a significantly higher decrease in OSAS symptoms than the pre-AT baseline score. (4) Conclusion: Future studies should pay more attention to characterizing patient populations as well as rapid surgical treatments through existing criteria. [ABSTRACT FROM AUTHOR]

Secondary aphonia significantly affects the quality of life of the laryngectomy patient despite the excellent success of the operation. Vocal rehabilitation often does not achieve the desired results, given the innumerable prognostic variables. Tracheo-oesophageal speech is considered the standard gold method of voice restoration, but a possible spasm of pharyngo-oesophageal segment is the prominent cause of rehabilitation failure. However, the phenomenon is difficult to identify and underestimated, and diagnostic methods are inquisitive or expensive. To propose a phonatory and swallowing evaluation essay of pharynx-oesophageal segment disorders, we conducted a retrospective study from 2012 to 2017 by selecting 6 patients who underwent total laryngectomy and voice prosthesis implantation that suffered from aphonia after surgery. All patients underwent dynamic phonation videofluoroscopy and plexus bath control test with lidocaine hydrochloride. All patients were then referred for treatment with neurotoxin blocker. In all cases, the analysed patients presented an air-trapping phenomenon with the formation of a spasmodic block upstream of an interrupted aerial column. The control test with lidocaine hydrochloride resulted in a transient improvement in speech performance. The neurotoxin block therapy subsequently performed ultimately led to an improvement in the patient's rehabilitation process with a recovery of the phonatory performance. We describe the new use of a barium bolus as a diagnostic tool for identifying neopharynx disorders. Appropriately selected patients with pharynx-oesophageal segment disorders could benefit from a neurotoxin-blocking treatment to improve oesophageal speech. [ABSTRACT FROM AUTHOR]

Purpose: The progression of the otitic infectious process toward diseases of particular severity is often unpredictable, just as it is challenging to manage the patient over time, even after the apparent resolution of the disease. We aim to define a radiological reading key that allows us to correctly and promptly treat the disease, avoiding the possible severe complications. Methods: We conducted a retrospective study of 13 cases of basal cranial osteomyelitis (SBO) due to malignant external otitis, by the ENT Department of the University of Catania. Through a standardized approach and following the latest guidelines, we have evaluated all patients performing a standardized and personalized radiological protocol according to the stage of the patient's pathology and modulating the treatment consequently. Results: Clinical signs have been observed such as otorrhea (100%), otalgia in 13/13 patients (100%), granulations in external auditory canal (100%), preauricular cellulitis in 9/13 patients (69%) headache 6/13 cases (46%), dysphonia 4/13 cases (31%). HRCT of the temporal bone proved useful in identifying even minimal bone lesions in 13/13 (100%) while improving MRI in vascular and nervous involvement, although in 1/13 patient with nerve palsy clinical symptomatology preceded radiological evidence. The 99mTc 3-phase planar bone scintigraphy was positive for SBO in 9/13 cases (69%) during the initial phase and, in 100% of the cases in images delayed to 2-3 hours. Subsequent checks up to 1 year, using the Ga 67 scintigraphy, excluded the presence of recurrences in 100% of patients. Conclusion: The osteomyelitis of the base of the skull is a severe complication of malignant external otitis, often not always easily diagnosed. Recurrence can occur up to 1 year after stopping therapy. Imaging techniques such as Tc and MRI are relevant for the initial diagnostic approach and the staging of the pathology and its complications. Nuclear medicine imaging plays a fundamental role in the evaluation of related osteoblastic activity, especially in the remission phase of the disease. [ABSTRACT FROM AUTHOR]

Smoking progressively damages the efficiency of mucociliary clearance (MCC) defense mechanisms, thus contributing to increased susceptibility to respiratory infections. Prolonged mucociliary clearance transit time (MCCTT) caused by chronic smoking has been investigated by saccharin test, but little data is available about its short- and long-term reproducibility. Moreover, it is not known if MCC impairment can be reversed when stopping smoking. Objective of the study is to investigate and compare short (3 days) and long term (30 days) repeatability of baseline saccharin transit time (STT) among current, former, and never smokers. STT results were analyzed in 39 current, 40 former, and 40 never smokers. Significant (p < 0.0001) short-term and long-term repeatability of STT were observed in current (R squared = 0.398 and 0.672, for short- and long-term, respectively) and former smokers (R squared = 0.714 and 0.595, for short- and long-term, respectively). Significant differences in MCCTT were observed among the three study groups (p < 0.0001); the median (IQR) MCCTT being 13.15 (10.24–17.25), 7.26 (6.18–9.17), and 7.24 (5.73–8.73) minutes for current, former and never smokers, respectively. Comparison between current smokers and former smokers was significantly different (p < 0.0001). There was no significant difference between former and never smokers. The Saccharin test was well tolerated by all participants. We have shown for the first time high level repeatability in both current and former smokers. Moreover, MCC impairment can be completely reversed, former smokers exhibiting similar STT as never smokers. Measurement of STT is a sensitive biomarker of physiological effect for the detection of early respiratory health changes and may be useful for clinical research. [ABSTRACT FROM AUTHOR]

Objective: Unusual clinical course. Background: The coronavirus disease 2019 (COVID-19) pandemic that spread from China is caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). The head and neck region can be variably affected in adult patients, and taste and smell disorders are typical manifestations. However, pediatric clinical signs are less severe, making the onset diagnosis challenging to interpret. The variability of nasal olfactory symptoms in children and adolescents is intertwined with possible warning signs, including gastrointestinal, ocular, or dermatological symptoms. We present a case involving a 15-year-old boy with clinically confirmed COVID-19 who had late-onset rash and transient taste and smell disorders. Case Report: The boy's clinical history revealed that a family member was positive for SARS-CoV-2. In the preceding 3 days, the boy's eating habits had changed; he perceived a metallic taste while eating and had a loss of appetite. He also had erythematous skin lesions on the lower limbs for the 2 previous days. A sore throat, nasal congestion, and a runny nose were reported on head and neck examination. A real-time polymerase chain reaction test was positive, confirming the initial diagnostic hypothesis. Conclusions: SARS-CoV-2 virus infection in children and adolescents can be asymptomatic, but it can also occur with fever, dry cough, fatigue, and gastrointestinal symptoms. Due to the unique immune characteristics of pediatric and adolescent patients, the correct interpretation of the gustatory and skin symptoms associated with specific laboratory tests for SARS-CoV-2 infection can lead to the most appropriate management and supportive care.

Obstructive Sleep Apnea Syndrome (OSAS) is a respiratory sleep disorder characterised by repeated episodes of partial or complete obstruction of the upper airway during the night. This obstruction usually occurs with a reduction (hypopnea) or complete cessation (apnea) of the airflow in the upper airways with the persistence of thoracic-diaphragmatic respiratory movements. During the hypopnea/apnea events, poor alveolar ventilation reduces the oxygen saturation in the arterial blood (SaO2) and a gradual increase in the partial arterial pressure of carbon dioxide (PaCO2). The direct consequence of the intermittent hypoxia is an oxidative imbalance, with reactive oxygen species production and the inflammatory cascade's activation with pro and anti-inflammatory cytokines growth. Tumour necrosis factors, inflammatory cytokines (IL2, IL4, IL6), lipid peroxidation, and cell-free DNA have been found to increase in OSAS patients. However, even though different risk-related markers have been described and analysed in the literature, it has not yet been clarified whether specified inflammatory bio-markers better correlates with OSAS diagnosis and its clinical evolution/comorbidities. We perform a scientific literature review to discuss inflammatory and oxidative stress biomarkers currently tested in OSAS patients and their correlation with the disease's severity and treatment.
