CT evaluation of interstitial lung disease related to systemic sclerosis: visual versus automated assessment. A systematic review.

AIM: To identify similarities and differences between visual (VA) and automated assessment (AA) of systemic sclerosis-related interstitial lung disease (SSc-ILD) at chest computed tomography (CT) in terms of clinical applicability. MATERIALS AND METHODS: Medline, Embase, and Web of Science were searched to identify all studies investigating VA and AA for SSc-ILD assessment, from inception to 31 July 2022. Exclusion criteria were manuscripts not in English, absence of full-text, reviews, diseases other than ILD in SSc, CT not analysed with both VA and AA, VA and AA not adopted for the same purpose or not compared, overlap syndromes, SSc-ILD data not extractable, and studies with <10 patients. RESULTS: Ten full-text studies (804 patients) were included. The most adopted VAs were the Warrick or Goh score (four studies each), while densitometry (eight studies) or lung texture analysis (LTA, two studies) were utilised as AAs. The main field of investigation was the correlation with baseline pulmonary function tests (PFT, six studies). Warrick VA showed lower correlations compared to densitometry, while Goh VA demonstrated more heterogeneous results. Compared to LTA, Goh VA obtained lower correlations with lung volumes but similar or stronger coefficients with alveolar diffusibility. CONCLUSIONS: VA and AA may show heterogeneous results comparing their correlations with PFT, probably depending on the specific analysis adopted for each method. More data are needed on VA versus LTA. Comparisons between VA and AA regarding correlation with PFT follow-up and as prognostic elements, or for disease monitoring, are lacking. AAs in progressive fibrosis diagnosis remain to be tested.

Vocal Tract Discomfort and Dysphonia in Patients Undergoing Empiric Therapeutic Trial with Proton Pump Inhibitor for Suspected Laryngopharyngeal Reflux.

INTRODUCTION: the aim of this study was to evaluate the correlation among dysphonic and vocal tract discomfort symptoms in patients who underwent empiric therapeutic trial with proton pump inhibitor (PPI) for a suspected laryngopharyngeal reflux (LPR). MATERIALS AND METHODS: A total of 34 patients with suspected LPR were enrolled in this study. All of them were evaluated using the reflux finding score, the reflux symptom Index (RSI), the vocal tract discomfort scale (VTDS), and the voice symptom scale (VoiSS) before and after the PPI treatment. RESULTS: A significant difference was found between pretreatment and posttreatment reflux finding score, RSI, VTDS, and VoiSS scores. Significant correlations among RSI, VTDS, and VoiSS before the PPI treatment were found. CONCLUSION: PPI treatment determined a significant improvement of symptoms related to dysphonia and vocal tract discomfort in patients with suspected LPR, in addition, significant correlations among the RSI, VTDS, and VoiSS scores were demonstrated thus suggesting that LPR might influence the response of questionnaires not specifically developed in order to assess the complains in LPR patient.

Double-blind, randomised controlled trial on the efficacy of saline nasal irrigation with sodium hyaluronate after endoscopic sinus surgery.

OBJECTIVE: There is a growing interest in sodium hyaluronate for the clinical management of patients who undergo functional endoscopic sinus surgery for chronic rhinosinusitis, because of the mucosal regenerative properties of this macromolecule. However, its role in post-operative care is still debated. This study aimed to evaluate the effect of sodium hyaluronate administered via nasal irrigation with saline, in the post-operative period, after functional endoscopic sinus surgery. METHODS: A multicentric, prospective, randomised, double-blind, parallel group study was conducted on 56 consecutive patients who underwent functional endoscopic sinus surgery for chronic rhinosinusitis without polyps. Group 1 received the standard therapy of normal saline; group 2 received saline plus sodium hyaluronate. RESULTS: Both objective and subjective measurements, in terms of endoscopic appearance and patient-reported satisfaction, were significantly better in group 2 compared to group 1. CONCLUSION: Sodium hyaluronate may be a useful adjunct to nasal saline irrigation in the early post-operative period following functional endoscopic sinus surgery.

Horizontal lateral lamella as a risk factor for iatrogenic cerebrospinal fluid leak. Clinical retrospective evaluation of 24 cases.

BACKGROUND: Several authors highlighted the limitations of the Keros classification system in predicting intracranial entry risk. Recently, our group proposed a new classification system based on the angle formed between the lateral lamella of the cribriform plate (LLCP) and the continuation of an horizontal plane passing through the cribriform plate (Gera classification). The aim of this study was to analyze whether the risk of iatrogenic cerebrospinal fluid leak (CSF-L) was better predicted by Keros or Gera classification. METHODOLOGY: The pre-operative CT scans of 24 patients (CSF-L group) who suffered from iatrogenic CSF-L during endoscopic sinus surgery (ESS) were compared to those obtained from a group of 100 patients who underwent uneventful ESS (control group). The skull base measurements as well as the distribution of Keros and Gera classes in the 2 groups were analyzed. RESULTS: No difference in the distribution of Keros classes or in the depth of the cribriform plate between CSF-L and control group were demonstrated. On the contrary, significant differences in the distribution of Gera classes and in the degree of the angle formed by the LLCP and the continuation of the horizontal plane passing through the cribriform plate were found. In particular, according to Gera classification system, 19 out of 24 patients in the CSF-L group were considered at risk for iatrogenic CSF-L. CONCLUSIONS: Gera classification system might be more sensitive to anatomical variations associated with CSF-L than the Keros one, further suggesting the application of the former during the preoperative CT scan evaluation.

Lateral lamella of the cribriform plate, a keystone landmark: proposal for a novel classification system.

BACKGROUND: The aim of this study is to propose a classification of the angle formed by the lateral lamella of the cribriform plate (LLCP) and the horizontal plane passing through the cribriform plate. In particular, the angle was classified into class I (over 80 degrees), class II (45 to 80 degrees, and class III (under 45 degrees) METHODOLOGY: A total of 190 computed tomography scans were retrospectively reviewed in order to obtain four sets of measurements. 1) depth of the cribriform, 2) angle, 3) length of the LLCP, 4) width of the fovea ethmoidalis. The relationship among these measurements were analyzed. RESULTS: The angle was significantly correlated with the depth of the cribriform and the length of the fovea, while it was negatively correlated with the length of the LLCP. Significant negative correlation was also found between the length of the LLCP and the width of the fovea. CONCLUSIONS: This angle classification is based on the theoretical risk of iatrogenic injuries, but it could be helpful also in clinical practice by providing indirect information on the thickness of the anterior skull base. As the angle decreases, in fact, the portion of the anterior skull base composed by the LLCP, increases.

Modern management of paediatric obstructive salivary disorders: long-term clinical experience.

Recent technological improvements in head and neck field have changed diagnostic and therapeutic strategies for salivary disorders. Diagnosis is now based on colour Doppler ultrasonography (US), magnetic resonance (MR) sialography and cone beam 3D computed tomography (CT), and extra- and intracorporeal lithotripsy, interventional sialendscopy and sialendoscopy-assisted surgery are used as minimally invasive, conservative procedures for functional preservation of the affected gland. We evaluated the results of our long-term experience in the management of paediatric obstructive salivary disorders. The study involved a consecutive series of 66 children (38 females) whose obstructive salivary symptoms caused by juvenile recurrent parotitis (JRP) (n = 32), stones (n = 20), ranula (n = 9) and ductal stenosis (n = 5). 45 patients underwent interventional sialendoscopy for JRP, stones and stenoses, 12 a cycle of extracorporeal shockwave lithotripsy (ESWL), three sialendoscopy-assisted transoral surgery, one drainage, six marsupialisation, and two suturing of a ranula. Three children underwent combined ESWL and interventional sialendoscopy, and seven a secondary procedure. An overall successful result was obtained in 90.9% of cases. None of the patients underwent traditional invasive sialadenectomy notwithstanding persistence of mild obstructive symptoms in six patients. No major complications were observed. Using a diagnostic work-up based on colour Doppler US, MR sialography and cone beam 3D TC, children with obstructive salivary disorders can be effectively treated in a modern minimally-invasive manner by extracorporeal and intracorporeal lithotripsy, interventional sialendoscopy and sialendoscopy-assisted transoral surgery; this approach guarantees a successful result in most patients, thus avoiding the need for invasive sialadenectomy while functionally preserving the gland.

Cross-Cultural Adaptation and Validation of the Italian Version of the Voice Symptom Scale (I-VoiSS).

OBJECTIVES: To evaluate the reliability and validity of the Italian Voice Symptom Scale (I-VoiSS). STUDY DESIGN: Cross-sectional, nonrandomized, prospective study with controls. METHODS: The study consisted of five phases: item generation, reliability analysis, normative data generation, validity and responsiveness analysis. A group of 113 dysphonic patients was enrolled for the internal consistency analysis. Seventy-three of them completed the I-VoiSS twice, 2 weeks apart, for test-retest reliability analysis. A group of 150 vocally healthy participants completed the I-VoiSS for normative data generation. I-VoiSS scores obtained by dysphonic and vocally healthy participants were compared for validity analysis. I-VoiSS scores were correlated with those of the Italian version of the Voice Handicap Index (I-VHI) in 49 dysphonic patients for criterion validity analysis. I-VoiSS scores obtained in a group of 37 nonsmoker dysphonic patients before and after surgical treatment for vocal fold polyps were compared for responsiveness analysis. Finally, the cutoff value of the I-VoiSS was calculated. RESULTS: All the enrolled participants managed to complete the I-VoiSS autonomously. Internal consistency and test-retest were satisfactory (α = 0.92 and r = 0.91). A significant difference in the I-VoiSS scores between the dysphonic and vocally healthy participants was found (p = 0.001). Positive significant correlations were found between I-VoiSS and I-VHI scores (r = 0.85). I-VoiSS scores obtained in the pretreatment condition were significantly higher than those obtained after surgery (p = 0.001). The cutoff value of I-VoiSS was 15.5. CONCLUSION: I-VoiSS is reliable, valid, responsive to changes, and recommended for clinical practice and outcome research.

Orthopaedic treatment effects of functional therapy on the sagittal pharyngeal dimensions in subjects with sleep-disordered breathing and Class II malocclusion.

The purpose of this cephalometric study was to evaluate the craniofacial changes induced by functional treatment of mandibular advancement with special regard to pharyngeal sagittal airway dimensions, tongue and hyoid bone position in subjects with sleep-disordered breathing (SDB) and dentoskeletal Class II malocclusions compared with an untreated Class II control group. 51 subjects (24 female, 27 male; mean age 9.9 ± 1.3 years) with Class II malocclusion and SDB consecutively treated with a functional appliance (Modify Monobloc, MM) were compared with a control group of 31 subjects (15 males, 16 females; mean age 10.1 ± 1.1) with untreated Class II malocclusion. For the study group, mode of breathing was defined by an otorhinolaryngologist according to complete physical examination. The parents of all participants completed a modified version of the paediatric sleep questionnaire, PSQ-SRBD Scale, by Ronald Chervin (the Italian version in 22 items form) before and after the trial. Lateral cephalograms were available at the start and end of treatment with the MM. Descriptive statistics were used for all cephalometric measurements in the two groups for active treatment changes. Significant, favourable skeletal changes in the mandible were observed in the treated group after T2. Significant short-term changes in sagittal airway dimensions, hyoid position and tongue position were induced by functional therapy of mandibular advancement in subjects with Class II malocclusion and SDB compared with untreated controls. After orthodontic treatment, a significant reduction in diurnal symptoms was observed in 45 of the 51 participants who had received an oral appliance. Orthodontic treatment is considered to be a potential therapeutic approach for SDB in children. Orthodontists are playing an increasingly important role in managing snoring and respiratory problems by oral mandibular advancement devices and rapid maxillary expansion.

Cross-cultural adaptation and validation of the SNOT-22 into Italian.

The aim of this study is to evaluate the reliability and validity of the Italian SNOT-22 (I-SNOT-22). The study consisted of five phases: item generation, reliability analysis, normative data generation, validity analysis and responsiveness analysis. The item generation phase followed the five-step, cross-cultural, adaptation process of translation and back-translation. A group of 222 patients with chronic rhinosinusitis (CRS) were enrolled for the internal consistency analysis. Sixty patients completed the I-SNOT-22 twice, 2 weeks apart, for test-retest reliability analysis. A group of 119 asymptomatic subjects completed the I-SNOT-22 for normative data generation. I-SNOT-22 scores obtained by CRS patients and asymptomatic subjects were compared for validity analysis. I-SNOT-22 scores were correlated with Lund-Mackay and visual analogue scale (VAS) scores in 50 CRS patients for criterion validity analysis. Finally, I-SNOT-22 scores obtained in a group of 59 CRS patients before and after surgical treatment for CRS were compared for responsiveness analysis. All the enrolled subjects managed to complete the I-SNOT-22 without needing any assistance. Internal consistency was satisfactory (α = 0.86). Test-retest reliability was also satisfactory (ICC = 0.85). A significant difference in the I-SNOT-22 scores between the CRS patients and the asymptomatic subjects was found (p < 0.008). Positive significant correlations were found between I-SNOT-22 and VAS scores, while no significant correlations were found between I-SNOT-22 scores and Lund-Mackay scores. I-SNOT-22 scores obtained in the pre-treatment condition were significantly higher than those obtained after surgery. I-SNOT-22 is reliable, valid, responsive to changes in QOL, and recommended for clinical practice and outcome research.

Aspects of cerebral plasticity related to clinical features in acute vestibular neuritis: a "starting point" review from neuroimaging studies.

Vestibular neuritis (VN) is one of the most common causes of vertigo and is characterised by a sudden unilateral vestibular failure (UVF). Many neuroimaging studies in the last 10 years have focused on brain changes related to sudden vestibular deafferentation as in VN. However, most of these studies, also due to different possibilities across diverse centres, were based on different times of first acquisition from the onset of VN symptoms, neuroimaging techniques, statistical analysis and correlation with otoneurological and psychological findings. In the present review, the authors aim to merge together the similarities and discrepancies across various investigations that have employed neuroimaging techniques and group analysis with the purpose of better understanding about how the brain changes and what characteristic clinical features may relate to each other in the acute phase of VN. Six studies that strictly met inclusion criteria were analysed to assess cortical-subcortical correlates of acute clinical features related to VN. The present review clearly reveals that sudden UVF may induce a wide variety of cortical and subcortical responses - with changes in different sensory modules - as a result of acute plasticity in the central nervous system.

Outcomes of interventional sialendoscopy for obstructive salivary gland disorders: an Italian multicentre study.

Interventional sialendoscopy has become the predominant therapeutic procedure for the management of obstructive salivary disorders, but only a few multicentre studies of large series of patients with a long-term follow-up have been published. This Italian multicentre study involved 1152 patients (553 females; mean age 50 years) who, after at least a clinical and ultrasonographic evaluation, underwent a total of 1342 diagnostic and interventional sialendoscopies, 44.6% of which involved the parotid gland. 12% (n = 138) of patients underwent multiple treatments. The procedure was successful in 1309 cases. In 33 cases (2.4%) the procedure could not be concluded mainly because of complete duct stenosis (21 cases). Salivary stones were the main cause of obstruction (55%), followed by ductal stenosis and anomalies (16%), mucous plugs (14.5%) and sialodochitis (4.7%). Complete therapeutic success was obtained in 92.5% of patients after one or more procedures, and was ineffective in < 8%. Untoward effects (peri and postoperative complications) were observed in 5.4% of cases. Sialendoscopy proved to be an effective, valid and safe procedure in the diagnostic and therapeutic management of non-neoplastic obstructive salivary gland diseases.

Cross-cultural adaptation and validation of the Nijmegen Cochlear Implant Questionnaire into Italian.

The NCIQ is a quantifiable self-assessment health-related quality of life instrument specific for cochlear implant users. The aim of this study was to culturally adapt the NCIQ into Italian (I-NCIQ). A prospective instrument validation study was conducted. Cross-cultural adaptation and validation were accomplished. Cronbach α was used to test internal consistency in 51 CI users and in a control group composed by 38 post-lingual deaf adult on a waiting list for a CI. ICC test was used for test-retest reliability analysis. Kruskal-Wallis test with Mann-Whitney post hoc were used to compare the I-NCIQ scores in CI users before and after the cochlear implantation and in control patients. I-NCIQ scores obtained in CI users were compared with the results of Italian version of disyllabic testing without lip-reading and without masking. Good internal consistency and good test-retest reliability were found. I-NCIQ scores obtained in the 51 CI users after implantation were consistently higher than those obtained before implantation and in the control group. Moreover, no differences were found in the results of I-NCIQ obtained in the group of 51 CI users before implantation and in the group of control patients on post hoc Mann-Whitney analysis. Positive correlations between I-NCIQ scores and the results of disyllabic testing without lip-reading and without masking were found. The I-NCIQ is a reliable, valid, self-administered questionnaire for the measurement of QOL in CI users; its application is recommended.

Temporo-mandibular joint chondrosarcoma: Case report and review of the literature.

Chondrosarcoma is a malignant mesenchymal tumour of cartilaginous origin. It represents 11% of all malignant primary bone tumours, and the pelvis, ribs, femur and humerus are most frequently involved. Chondrosarcoma of the head and neck region is a rare disease, and represents approximately 0.1% of all head and neck neoplasms. This report describes a rare localisation of chondrosarcoma in a 56-year-old man who presented with swelling in the right preauricular area and mild limitation and pain in the mouth opening. Since 1959, just a few cases of temporomandibular joint (TMJ) chondrosarcoma have been described. Computed tomography revealed a large mass (39 x 46 x 40 mm) in the right preauricular and parotid region with morpho-structural alterations of the condyle and an intense periostotic reaction. The tumour was treated by total parotidectomy and condylotomy. The VII cranial nerve was preserved. Histopathologic examination revealed a low grade chondrosarcoma with a 50% proliferation index. At present, the patient is still receiving routine follow-up after radiotherapy and physiotherapy.

Utility of Glidescope(®) videolaryngoscopy in surgical procedures involving the larynx.

GlideScope(®) is a recently developed videolaryngoscope that helps to achieve a good view of the laryngeal inlet and the vocal cords. Videolaryngoscopy has been proven effective in patients with unusual anatomical or pathological features, suggesting the possibility of a difficult endotracheal intubation. This device may also be useful for otorhinolaryngologists by facilitating access to the larynx and tongue base, especially in selected cases, where good visualisation of disease-altered structures is vital. According to the current literature, GlideScope(®) has been used for surgical procedures involving the tongue base, such as biopsies, foreign body removal and radiofrequency treatment of obstructive sleep apnoea. We believe that the use of this kind of videolaryngoscopy might be also indicated for laryngeal surgery as a valid alternative to the placement of a direct laryngoscope. This technique, especially in those cases with anatomical issues or important comorbidities, may be preferred to ambulatorial flexible or rigid laryngoscopy, and in planning surgical procedures in "difficult" patients due to the operating room setting comprising constant anaesthesiological support. In our experience, we performed five procedures involving the larynx with the GlideScope(®) in patients presenting unusual clinical characteristics that potentially compromised surgical outcome. No complications related to videolaryngoscopy were found. We recommend the use of GlideScope(®) for small surgical procedures involving the larynx in selected patients.

Meta-analysis of recurrent laryngeal nerve injury in thyroid surgery with or without intraoperative nerve monitoring.

Intraoperative nerve monitoring (IONM) aimed at reducing the injuries of recurrent laryngeal nerve during thyroidectomy is controversial. We conducted a meta-analysis to assess the incidence of nerve injuries with or without IONM. Studies published from January 1994 to February 2012 in English language on humans were identified. Heterogeneity of studies was checked by the Higgins test. Summary estimates of predictive values of injury were made using the Mantel-Haenszel test based on the fixed-effects model. Publication bias was assessed by a funnel plot and Egger's method. Eight articles were selected accounting a total of 5257 nerves at risk. IONM revealed a significant impact in preventing transient injuries (positive predictive value = 5% [95% CI: 2-8], negative = 96% [95% CI: 91-100], relative risk = 0.73 [95% CI: 0.54-0.98], p = 0.035), whereas they failed to demonstrate effect on permanent injuries (positive predictive value = 2% [95% CI: 0.6-3.8], negative 99% [95% CI: 97-100], relative risk = 0.73 [95% CI: 0.44-1.23], p = 0.235). This meta-analysis demonstrated the merit of IONM in preventing transient injury during thyroidectomy. No advantage was found in permanent injuries.

Intranasal administration of hyaluronan as a further resource in olfactory performance in multiple chemical sensitivity syndrome.

Multiple chemical sensitivity (MCS) is a relatively common clinical diagnosis in western populations and its symptoms (i.e. dysosmia) are mainly triggered by chemical compounds, such as common odorants. The aim of this study was to test the effect of intranasal administration of hyaluronic acid (HA) on odour threshold and related quality of life in MCS syndrome. Two randomized groups of MCS patients received 30 days’ administration of either a nasal spray (Ialumar®) containing HA [HA group (HAG); n=29] or only physiological solution[PS group (PG); n=30]. Both groups were investigated using the Sniffin’ Sticks test (SST) battery, Questionnaire of Olfactory Disorder (QOD) and Zung Anxiety Scale (SAS) before randomization and after treatment. Paired t-test analysis found a statistically significant reduction in odour threshold (OT) and an improvement in QOD and SAS between pre- and post-treatment results only in the HAG. Furthermore, positive correlations were found between the OT reduction, SAS and QOD improvement. Thus, intranasal administration of HA could be suggested as a further well-tolerated resource in alleviating MCS olfactory discomfort.

Reliability of the Italian INFVo scale and correlations with objective measures and VHI scores.

The objective of this study was to evaluate the reliability of the INFVo scale and its relationship with objective measures and VHI scores in 40 native Italian-speaking patients with substitution voice. The maximum phonation time (MPT), diadochokinesis (DDK) of the three syllabic sequence [pa/ta/ka], reading of a passage and a single word repetition test were recorded. Each patient completed the Italian version of the VHI. Three speech-language pathologists blindly rated the recordings using the auditory perceptual INFVo scale; one listened and assessed the voice recording twice. The INFVo intra- and inter-rater reliability reached good values. Strong to moderate correlations between the INFVo scale scores and MPT, DDK, distortions in the repetition test, speech rate during reading and the functional subscale of the VHI were found. In conclusion, the INFVo scale is a reliable tool and can be recommended for the perceptual assessment of substitution voices in Italian speaking patients.

Vocal improvement after voice therapy in the treatment of benign vocal fold lesions.

Benign vocal fold lesions are common in the general population, and have important public health implications and impact on patient quality of life. Nowadays, phonomicrosurgery is the most common treatment of these lesions. Voice therapy is generally associated in order to minimize detrimental vocal behaviours that increase the stress at the mid-membranous vocal folds. Nonetheless, the most appropriate standard of care for treating benign vocal fold lesion has not been established. The aim of this study was to analyze voice changes in a group of dysphonic patients affected by benign vocal fold lesions, evaluated with a multidimensional protocol before and after voice therapy. Sixteen consecutive patients, 12 females and 4 males, with a mean age of 49.7 years were enrolled. Each subject had 10 voice therapy sessions with an experienced speech/language pathologist for a period of 1-2 months, and was evaluated before and at the end of voice therapy with a multidimensional protocol that included self-assessment measures and videostroboscopic, perceptual, aerodynamic and acoustic ratings. Videostroboscopic examination did not reveal resolution of the initial pathology in any case. No improvement was observed in aerodynamic and perceptual ratings. A clear and significant improvement was visible on Wilcoxon signed-rank test for the mean values of Jitt%, Noise to Harmonic Ratio (NHR) and Voice Handicap Index (VHI) scores. Even if it is possible that, for benign vocal fold lesions, only a minor improvement of voice quality can be achieved after voice therapy, rehabilitation treatment still seems useful as demonstrated by improvement in self-assessment measures. If voice therapy is provided as an initial treatment to the patients with benign vocal fold lesions, this may lead to an improvement in the perceived voice quality, making surgical intervention unnecessary. This is one of the first reports on the efficacy of voice therapy in the management of benign vocal fold lesions; further studies are needed to confirm these preliminary data.

Surgical management of a life-threatening retro-pharyngeal haematoma following trans-oesophageal echocardiography.

Trans-oesophageal echocardiography is generally considered a safe procedure, but occasional life-threatening complications have been reported. The aim of this clinical investigation is to outline the need of surgical management in cases of large retro-pharyngeal haematoma following trans-oesophageal echocardiography. In the case reported here, a patient with cervical spondylosis on anti-coagulant therapy was referred to the Head and Neck Department because of a retro-pharyngeal haematoma with severe upper airway obstruction following transoesophageal echocardiography. Tracheotomy was required to guarantee respiratory function, while trans-cervical surgery was performed to evacuate the haematoma. Total recovery was achieved within 10 days. In conclusion, the head and neck surgeon should consider the need of surgical management in cases of retro-pharyngeal haematoma following trans-oesophageal echocardiography.
