RESUMO
PURPOSE: Positional obstructive sleep apnea (POSA) has been defined as a difference of 50% or more in Apnea-Hypopnea Index (AHI) between supine and non-supine position. Sleep position is fundamental in the evaluation of obstructive sleep apnea syndrome (OSAS) severity but most tools used in the diagnosis of OSAS are not free from potential bias in the evaluation of usual sleep positions. The aim of this investigation was to evaluate a novel sleep questionnaire with the purpose of exploring sleep habits and evaluating if sleep assessment can identify the usual body position assumed for sleep. MATERIALS AND METHODS: The questionnaire was administered to patients recruited from October to November 2018. Questions concerned sleeping positions and conditions that could influence sleeping positions. Patients who had previously undergone polysomnography (PSG) were asked how they slept during the study night. Whenever present during the examination, the patient's bed partner was also asked about the patient's usual body positions during sleep. RESULTS: Of 315 patients (211 men) enrolled, 35% were affected by OSAS and 69% of patients with OSAS had POSA. POSA was more prevalent among men (75%) compared to women (43%). The new questionnaire provided a discordant result from PSG recordings about sleeping positions and revealed a difference between usual sleeping position and the position during PSG recording. Reported sleep quality was much worse on PSG than at home suggesting that the "first night effect" is real and may lead to over-estimation of POSA cases. CONCLUSIONS: Information about sleeping positions is fundamental to the assessment of OSAS severity. Knowledge gained from the new questionnaire as described may represent a valuable addendum to develop a more detailed polygraphic report. Such a tool may be used in practice with the aim of better identifying patients with true positional OSAS. Such patients may benefit from targeted positional therapy.

BACKGROUND: Obstructive sleep apnea (OSA) is the most common sleep disorder due mainly to peripheral causes, characterized by repeated episodes of obstruction of the upper airways, associated with arousals and snoring. Sleep bruxism (SB) is a masticatory muscle activity during sleep that is characterized as rhythmic (phasic) or nonrhythmic (tonic) and is not a movement disorder or a sleep disorder in otherwise healthy individuals. Given the potentially severe consequences and complications of apnea, the concurrent high prevalence of SB in daily dental practice, getting deeper into the correlation between these phenomena is worthy of interest.. STUDY OBJECTIVES: The aim of this study was to investigate the correlation between SB-related masseter muscle activity (MMA) and apnea-hypopnea events as well as to assess their temporal sequence. METHODS: Thirty (N = 30) patients with sleep respiratory disorders and clinical suspicion of sleep bruxism (SB) were recruited. Ambulatory polygraphic recording was performed to detect apnea-hypopnea events (AHEs) and sleep bruxism episodes (SBEs). Pearson test was used to assess the correlation between apnea-hypopnea index (AHI) and SB index (SBI). A 5-s time window with respect to the respiratory events was considered to describe the temporal distribution of SBEs. Furthermore, SBI was compared between groups of patients with different AHI severity (i.e., mild, moderate and severe) using ANOVA. RESULTS: On average, AHI was 27.1 ± 21.8 and SBI 9.1 ± 7.5. No correlation was shown between AHI and SBI. Most of SBEs (66.8%) occurred without a temporal relationship with respiratory events. Considering OSA, 65.7% of SBEs occurred within 5 s after AHEs, while in the case of central apnea (CA) 83.8% of SBEs occurred before the respiratory event. The participants with severe apnea (N = 9) show a tendency to have higher bruxism indexes when compared to patients with mild (N = 11) and moderate apnea (N = 10). CONCLUSIONS: Findings suggest that: 1. At the study population level, there is no correlation between AHI and SBI, as well as any temporal relationship between SBEs and respiratory events. 2. Specific patterns of temporal relationship might be identified with future studies focusing on the different types of apnea-hypopnea events and bruxism activities.

OBJECTIVE: To present a case of sudden sensorineural hearing loss (SSNHL) and the related diagnostic workup. CLINICAL PRESENTATION AND INTERVENTION: A 54-year-old man presented with a unilateral SSNHL episode and vertigo. A severe patent foramen ovale (PFO) that included a complete ear nose and throat, audiological, and neurological examination was discovered during the diagnostic workup. Audiometry, blood, and serological tests were performed. Magnetic resonance imaging and color Doppler echography of the supra-aortic trunks and lower limbs were carried out. Finally, transthoracic followed by transesophageal echocardiography and transcranial Doppler were performed in order to confirm the diagnosis of PFO. Medical therapy with systemic steroid and antiplatelet drugs was administered. CONCLUSIONS: This case showed a small PFO associated with an aneurysmatic interatrial septum. The PFO and paradoxical thromboembolism could be involved in the pathogenesis of SSNHL.

The aim of this review is to investigate the state of the art among the association between Obstructive sleep apnea (OSA) and laryngomalacia, analyzing the epidemiology, the diagnostic tools, and the possible treatments available to affected patients. Laryngomalacia, characterized by the malacic consistency of the epiglottis with a tendency to collapse during inspiratory acts, producing a characteristic noise known as stridor, is a common condition in infants and particularly in those affected by prematurity, genetic diseases, craniofacial anomalies, and neurological problems. Congenital laryngomalacia, presenting with stridor within the first 15 days of life, is often self-limiting and tends to resolve by 24 months. OSA is not only a consequence of laryngomalacia but also exacerbates and perpetuates the condition. Currently, the treatments reported in the literature are based (i) on medical therapies (including watchful waiting) and (ii) on surgical treatments. Among the surgical techniques, the most described is supraglottoplasty, performed with the use of cold instruments, CO2 LASER, transoral robotic surgery, or the microdebrider.
RESUMO
INTRODUCTION: Subcutaneous emphysema (SE) represents, after bleeding and infections, a common complication in ENT surgery, given the intimate relationship between upper airways and anatomical area pertaining head and neck surgeon. Aim of this review is to analyze its characteristics, method of diagnosis and treatment to provide the specialist a useful tool for its early recognition. EVIDENCE ACQUISITION: A narrative review was carried out in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. A total of 164 articles were collected and most of them were case reports. EVIDENCE SYNTHESIS: Of 273 articles taken into consideration, only 164 met inclusion criteria. Review of all cases of SE in relation to surgical ENT procedures allow to classify each etiology on the surgical procedure that could be complicated with SE: laryngo-tracheal procedures, thyroid surgery, nasal and otological surgery, adenotonsillectomies. Moreover, traumatic orotracheal intubation, as well as alveolar rupture because of positive pressure ventilation or rupture of a preexisting abnormality, must be always taken into account. CONCLUSIONS: All ENT surgery can be complicated by SE. Diagnosis is simple and usually based only on physical examination, but correct and quick diagnosis is required. Treatment is in most of the time exclusively conservative, but SE could also represent a surgical emergency, given the possible evolution in pneumothorax/pneumomediastinum with serious consequences for patient's health.

Background. To evaluate the possible effects of Rapid Maxillary Expansion (RME), such as nasal breathing problems, middle ear function, Obstructive Sleep Apnea (OSA) in the otolaryngology field. RME has already been introduced in orthodontics to expand the maxilla of young patients affected by transversal maxillary constriction. Methods. A literature search was performed using different databases (Medline/PubMed, EMBASE, and CINAHL), from May 2005 to November 2021, according to the PRISMA guidelines. Results. The application of RME in children has shown good results on nasal function, reducing nasal resistances, independently from a previous adenotonsillectomy. These results are not only related to the increasing of nasal transverse diameters and volume, but also to the stiffening of airway muscles, enabling the nasal filtrum function and avoiding mouth opening, thereby decreasing respiratory infections. Positive effects have also been reported for the treatment of conductive hearing loss and of OSA, with the reduction of Apnea Hypopnea Index (AHI), possibly due to (i) an increased pharyngeal dimensions, (ii) a new tongue posture, and (iii) reduced nasal respiratory problems. Conclusions. Otolaryngologists should be aware of the indications and benefits of the RME treatment, considering its possible multiple beneficial effects.
RESUMO
PURPOSE: The aim of our retrospective study is evaluating the effectiveness of barbed repositioning pharyngoplasty (BRP) in a consecutive cohort of patients and assessing its impact on positional indexes in order to potentially identify specific obstructive sleep apnea (OSA) phenotypes for patients who might benefit more significantly from this intervention. METHODS: A single-center retrospective study with baseline and follow-up type III sleep tests evaluating the Apnea Hypopnea Index (AHI), supine AHI, non-supine AHI, oxygen desaturation index (ODI), mean SaO2, percentage of time spent at SaO2 below 90% (CT90), and lowest oxygen saturation (LOS) were performed. The patients were then divided into groups according to Sher's criteria and Amsterdam Positional OSA Classification (APOC). Parametric and non-parametric tests and univariate and multivariate analyses were conducted. RESULTS: The study finally included 47 patients. The statistical analysis showed significant improvement in AHI, supine AHI, non-supine AHI, and ODI after surgery. The linear regression showed that high values of baseline AHI, AHI supine, and AHI non supine predict more significant postoperative reductions in AHI, AHI supine, and AHI non supine, respectively. Therapeutic success was achieved in 22 patients out of 47. The logistic regression did not find any independent risk factors for success. The most significant reduction in AHI, supine AHI, and non-supine AHI was observed in the APOC 3 group while the APOC 1 patients experience a substantially lower improvement. CONCLUSIONS: BRP appears to be an effective surgical procedure for the treatment of OSA. The non-positional patients might benefit more from BRP in comparison with positional patients. Moreover, OSA severity should not be considered an absolute contra-indication for this surgical procedure.
RESUMO
Purpose: Evaluate the effectiveness of the head-of-bed elevation position (HOBE) with a 30° elevation of the head and trunk, in improving obstruction of the upper airways in obstructive sleep apnea (OSA) patients. A prospective trial simultaneously performing drug-induced sleep endoscopy (DISE) and polysomnography (PSG) tests was performed. Methods: Forty-five patients were included in the prospective study protocol. All patients enrolled in the study and underwent the following evaluations: (1) a drug-induced sleep endoscopy, with an evaluation of obstructions and collapse of the upper airways at 0° and in a HOBE position, with head and trunk elevation of 30°; (2) an overnight PSG assessment in the hospital with head and trunk elevation from 0° to 30° during the night; (3) a questionnaire to evaluate the feedback of patients to sleeping with head-of-bed elevation. Results: Velum (V) and oropharynx lateral wall (O) collapses were reduced in the 30° up position. There were no statistical differences that emerged in the obstruction of the tongue base and epiglottis between the 0° position and the 30° up position (p > 0.05). The average AHI score changed from 23.8 ± 13.3 (0° supine position) to 17.7 ± 12.4 (HOBE position), with a statistical difference (p = 0.03); the same statistical difference emerged in the percentage of apneas that decreased from 55 ± 28.1 to 44 ± 25.8 (p = 0.05). Conclusions: By adopting the HOBE position with 30° elevation of the head and trunk, it is possible to obtain a reduction of upper airways collapses and an improvement of apnea/hypopnea events and nightly respiratory outcomes.
RESUMO
OBJECTIVE: Positional Obstructive Sleep Apnoea Syndrome (POSAS) is a sub-type of Obstructive Sleep Apnoea Syndrome (OSAS) in which obstructive apnoeas occur mainly in the supine sleeping position. In clinical practice, information on sleep posture is generally gathered by polysomnographic exam (PSG). The current trend in positional therapies consists of position trainers which help to avoid the supine position. The aim of this study is to detect the reliability of different devices on assessing sleeping position, comparing the data with objective evaluation by an infra-red camera. METHODS: We compared the positional results of 4 healthy volunteers obtained from a type III PSG and with a neck-worn sleep position trainer (Night Shift - NS). RESULTS: Data showed that NS is a good tool to assess the position of the trunk, with high rate of agreement with PSG, but in some conditions there are limitations, especially in detecting the real head and neck position and low accordance between NS data and information recorded by infra-red camera. CONCLUSIONS: Our study confirmed that more information about body position during sleep is needed, underling the necessity of developing new technologies that are able to better identify reciprocal body positions.

Despite improved prognosis for many HPV-positive head and neck squamous cell carcinomas (HNSCCs), some cases are still marked by recurrence and metastasis. Our study aimed to identify novel biomarkers for patient stratification. Classical HPV markers: HPV-DNA, p16 and HPV mRNA expression were studied in HNSCC (n = 67) and controls (n = 58) by qPCR. Subsequently, ELISA tests were used for HPV16 L1 antibody and HPV16 E7 oncoprotein detection in serum at diagnosis and follow-up. All markers were correlated to relapse-free survival (RFS) and overall survival (OS). HPV-DNA was found in HNSCCs (29.85%), HPV16-DNA in 95% of cases, HPV16 E7 mRNA was revealed in 93.75%. p16 was overexpressed in 75% of HPV-positive HNSCC compared to negative samples and controls (p < 0.001). Classical markers correlated with improved OS (p < 0.05). Serological studies showed similar proportions of HPV16 L1 antibodies in all HNSCCs (p > 0.05). Serum E7 oncoprotein was present in 30% HPV-positive patients at diagnosis (p > 0.05) and correlated to HNSCC HPV16 E7 mRNA (p < 0.01), whereas it was associated to worse RFS and OS, especially for oropharyngeal squamous cell carcinoma (OPSCC) (p < 0.01). Detection of circulating HPV16 E7 oncoprotein at diagnosis may be useful for stratifying and monitoring HPV-positive HNSCC patients for worse prognosis, providing clinicians a tool for selecting patients for treatment de-escalation.
RESUMO
BACKGROUND: Killian polyp (KP) is a benign lesion that arises from the maxillary sinus. The etiology of KP is unknown. The aim of this study was to investigate the potential involvement of human papilloma- (HPV) and polyoma-viruses (HPyV) infections in the onset of KP. METHODS: DNA from antral (n = 14) and nasal (n = 14) KP fractions were analyzed for HPV and HPyV sequences, genotypes, viral DNA load and physical status along with expression of viral proteins and p16 cellular protein. RESULTS: The oncogenic HPV16 was detected in 3/14 (21.4%) antral KPs, whilst nasal KPs tested HPV-negative (0/14). The mean HPV16 DNA load was 4.65 ± 2.64 copy/104 cell. The whole HPV16 episomal genome was detected in one KP sample, whereas HPV16 DNA integration in two KPs. P16 mRNA level was lower in the KP sample carrying HPV16 episome than in KPs carrying integrated HPV16 and HPV- negative KPs (p< 0.001). None of the antral and nasal KP samples tested positive for HPyV DNA (0/28). CONCLUSIONS: A fraction of KP tested positive for the oncogenic HPV16. HPV16 detection in the KP antral portion may be consistent with HPV16 infection derived from the maxillary sinus. HPV16 DNA integration represents a novel finding. Altogether, these data improve our knowledge on the association between KP and HPV infection, whereas it indicates that the KP onset is heterogeneous.
RESUMO
Background. Previous studies reported human papillomaviruses (HPVs) in middle ear tumors, whereas these viruses have been poorly investigated in chronic inflammatory middle ear diseases. We investigated HPVs in non-tumor middle ear diseases, including chronic otitis media (COM). Methods. COM specimens (n = 52), including chronic suppurative otitis media (CSOM) (n =38) and cholesteatoma (COMC) (n = 14), as well as normal middle ear (NME) specimens (n = 56) were analyzed. HPV sequences and DNA loads were analyzed by quantitative-PCR. HPV genotyping was performed by direct sequencing. Results. HPV DNA was detected in 23% (12/52) of COM and in 30.4% (17/56) of NME (p > 0.05). Specifically, HPV DNA sequences were found in 26.3% (10/38) of CSOM and in 14.3% (2/14) of COMC (p > 0.05). Interestingly, the HPV DNA load was higher in COMC (mean 7.47 copy/cell) than in CSOM (mean 1.02 copy/cell) and NME (mean 1.18 copy/cell) (P = 0.03 and P = 0.017 versus CSOM and NME, respectively). HPV16 and HPV18 were the main genotypes detected in COMC, CSOM and NME. Conclusions. These data suggest that HPV may infect the middle ear mucosa, whereas HPV-positive COMCs are associated with higher viral DNA loads as compared to NME.
RESUMO
Background: Acquired nasopharyngeal stenosis is a rare and heterogeneous pathological condition that has different causes, generally resulting as a complication of a pharyngeal surgery, especially in patients affected by obstructive sleep apnea (OSA). Different approaches have been proposed for the treatment of nasopharyngeal stenosis but a unique and standardized management has not yet been presented. The aim of our paper is to evaluate the efficacy of our surgical technique, describing its steps and results with the aim to consider it as a possible solution for the treatment of this condition. Methods: This is a retrospective cohort study. Eight patients (mean age 27.25 years old (yo), range 8-67 yo; Male/Female ratio 4/4; mean body mass index (BMI) 26.1) affected by OSA (mean apnea hypopnea index (AHI) before OSA surgery was 22.1) and acquired nasopharyngeal stenosis as a consequence of different pharyngeal surgeries were treated with our modified approach in the Department of Otolaryngology, Morgagni Pierantoni Hospital, Forlì, Italy. Resolution of stenosis and complication rate were the main outcome measures. Results: Complete resolution of the stenosis was achieved in all cases and no complications were recorded at three weeks, six months, and 2 years follow-up. Conclusions: Our technique appears to be a promising method for the management of nasopharyngeal stenosis in OSA patients. However, further studies comparing different techniques and reporting on larger series and longer follow up time are needed to prove the efficacy of the proposed technique.

Background The purpose of this study was to evaluate the prevalence of position-dependent obstructive sleep apnea (POSA) in elderly patients (≥65 years old). Adult (range 19-65 years old) and elderly patients were also compared in order to show differences in the incidence of POSA between these two groups of patients. Methods A prospective bi-center study was performed between January 2018 and May 2019. A total of 434 participants underwent polysomnography (PSG) study at home (Embletta MPR). Body position during the PSG recordings was determined. Patients were subdivided in two groups: those aged between 19 and 65 years old (adult patients) and ≥65 years old (elderly patients). POSA patients were defined using Cartwright's system, Bignold classification, and the new Amsterdam Positional OSA Classification (APOC). Results The prevalence of POSA in elderly patients differed according to the classification system used: 49.3% using Cartwright's classification system, 20.5% with the Bignold classification, and 22.6%, 38.9%, and 5.4% of APOC 1, APOC 2, and APOC3 sub-classes were respectively identified for the APOC classification system. No difference between adult and elderly patients regarding the prevalence of POSA was observed. No statistical differences emerged between the two groups of patients in terms of supine (p = 0.9) and non-supine AHI (p = 0.4). Conclusions A significant number of elderly patients could be considered treatable with positional therapy according to the APOC classification. However, the efficacy and applicability of positional therapy in elderly patients must be confirmed by further research.

Importance: Drug-induced sleep endoscopy is a diagnostic technique that allows dynamic evaluation of the upper airway during artificial sleep. The lack of a standardized procedure and the difficulties associated with direct visual detection of obstructive events result in poor intraobserver and interobserver reliability, especially when otolaryngology surgeons not experienced in the technique are involved. Objectives: To describe a drug-induced sleep endoscopy technique implemented with simultaneous polygraphic monitoring of cardiorespiratory parameters (DISE-PG) in patients with a diagnosis of obstructive sleep apnea syndrome and discuss the technique's possible advantages compared with the standard procedure. Design, Setting, and Participants: This prospective cohort study included 50 consecutive patients with obstructive sleep apnea syndrome who underwent DISE-PG from March 1, 2013, to June 30, 2014. A standard protocol was adopted, and all the procedures were carried out in an operation room by an experienced otolaryngology surgeon under the supervision of an anesthesiologist. Endoscopic and polygraphic obstructive respiratory events were analyzed offline in a double-blind setting and randomized order. Main Outcomes and Measures: The feasibility and safety of the DISE-PG technique, as well as its sensitivity in detecting respiratory events compared with that of the standard drug-induced sleep endoscopy procedure. Results: All 50 patients (43 men and 7 women; mean [SD] age, 51.1 [12.1] years) underwent DISE-PG without technical problems or patient difficulties regarding the procedure. As expected, polygraphic scoring was more sensitive than endoscopic scoring in identifying obstructive events (mean [SD] total events, 13.3 [6.8] vs 5.3 [3.6]; mean [SD] difference, 8.8 [5.6]; 95% CI, 7.3 to 10.4; Cohen d, -1.5). This difference was most pronounced in patients with a higher apnea-hypopnea index (AHI) at baseline (mean [SD] difference for AHI >30, 27.1% [31.0%]; 95% CI, -36.2% to 90.4%; Cohen d, 0.2; for AH I >40, 76.0% [35.5%]; 95% CI, 4.6% to 147.4%; Cohen d, 0.5; for AHI >50, 92.2% [37.2%]; 95% CI, 17.3% to 167.1%; Cohen d, 0.6) and a high percentage of hypopneas (≥75% of all obstructive events) at baseline (mean [SD] difference, 20.2% [5.4%]; 95% CI, 9.2% to 31.3%; Cohen d, 1.1). No other anthropomorphic or polygraphic features at baseline were associated with the differences between the DISE-PG and baseline home sleep apnea test. Conclusions and Relevance: The DISE-PG technique is feasible, safe, and more sensitive at detecting an obstructed breathing pattern than is drug-induced sleep endoscopy alone. The DISE-PG technique could be helpful for accurate comprehension of upper airway obstructive dynamics (ie, degree of obstruction and multilevel pattern) and a nonobstructive breathing pattern (ie, central apneas).

Dermatomyositis is an inflammatory myopathy characterized by proximal symmetrical muscle weakness with a characteristic cutaneous eruption. Population-based cohort studies provide evidence of an increased frequency of cancer in dermatomyositis patients. Many signs and serology tests have been suggested as markers for malignancy in dermatomyositis. We performed a case-control study on the patients admitted in our institutions for dermatomyositis. Clinical and laboratory data were collected and statistical analysis was performed to reveal important predictive signs of malignancy in dermatomyositis. We found no statistical difference in the clinical or laboratory parameters between the dermatomyositis patients with or without malignancy, with the exception of the erythrocyte sedimentation rate. In our study group an erythrocyte sedimentation rate higher than 35 mm/hr was very strongly associated with the presence or the development of a malignancy. Given the high positive and negative predictive values observed in our study, erythrocyte sedimentation rate evaluation using this cut-off point could be very useful in alerting dermatologists to the need for more in-depth diagnostic procedures in dermatomyositis patients.

BACKGROUND: Nail psoriasis is a common problem in psoriatic patients and often it is difficult to cure. Several treatments have been proposed in the last decade using new molecules like vitamin-D analog and/or immunosoppressive drugs both systemically and locally. OBJECTIVE: Our goal was to evaluate a combination of cyclosporin and topical calcipotriol cream versus cyclosporin alone in a matched group of patients treated with cyclosporin alone. METHOD: Fifty-four patients affected by severe psoriasis and nail involvement were selected and matched for severity of nail involvement, sex, age, and cyclosporin dosage. Group A included 21 patients treated with cyclosporin alone (3.5 mg/kg/day) for three months. Group B included 33 patients treated with the same cyclosporin dosage plus, for the same time, topical application of calcipotriol cream twice a day. Evaluation for clinical improvement was the personal feeling of the patient after three months, while clinical appearance of the lesions was evaluated by the same dermatologist using digital pictures and who was blind as to the treatment of the patient. A score ranging from + to +++ was used in order to evaluate the improvement, and data were statistically evaluated with the Wilcoxon test. RESULTS: Both cyclosporin alone and a combination of cyclosporin with topical calcipotriol twice a day were useful for treating nail psoriasis after three months of therapy although the combined therapy showed a better overall result in both mild and severe nail psoriasis. Improvement of the clinical appearance of the nail lesions was seen in about 79% of patients in group B (p < or = 0.0004) versus about 47% of patients in group A (p < or = 0.15). CONCLUSIONS: In patients with severe involvement of nail psoriasis we suggest the use of a combination of topical calcipotriol twice a day with systemic treatment such as cyclosporine.
