ABSTRACT
PURPOSE: The aim of this study was to provide an updated European narrative review spanning the last decade, focusing on the cost-effectiveness of cochlear implants (CIs) for adults with severe to profound post-lingual hearing loss. METHODS: This review encompasses both prospective and retrospective approaches, as well as cross-sectional and longitudinal trials conducted on CIs in adults. All studies related to European countries (Austria, Germany, Switzerland, the Netherlands, Sweden, the UK and Poland) were conducted in English and were published between 2012 and June 2023. RESULTS: Nine studies were included in the analysis. The patients' ages ranged from 18 years to over 67 years, with sample sizes ranging from 20 to 100 patients; two of these studies were focused on single-sided deafness in adults. The Markov model was identified as the most commonly utilized analysis method. CONCLUSIONS: This review identified a general consensus on CI cost-effectiveness, despite substantial variability among countries in factors such as observation time horizons, cost-effectiveness thresholds, methods of cost collection, discount rates, CI eligibility criteria and country-specific health systems. Generally, CIs yield positive societal benefits for working-age individuals, potentially less for seniors. Early unilateral CI enhances cost-effectiveness, highlighting the importance of prompt candidate identification. A consistent undersupply of CIs relative to the percentage of potential recipients emerged across countries. Therefore, further investigation into subcategories such as single-sided deafness is warranted, along with country-specific cost analyses. Emphasizing the significance of detailed information on health systems and associated costs and benefits is crucial for facilitating comparisons across different settings.
ABSTRACT
PURPOSE: To review possible risk factors for permanent delayed-onset, progressive sensorineural hearing loss (SNHL) in the paediatric population to recommend follow-up protocols for early detection. METHODS: PRISMA-compliant systematic review was performed, including observational studies on the paediatric population up to 16 years old who have passed the newborn hearing screening programme (NHSP), investigating the development of late-onset, progressive SNHL. Electronic searches were performed through Medline, Embase, Cochrane, and Emcare. RESULTS: 37 studies were included. 21 showed an association between late-onset SNHL and congenital cytomegalovirus (cCMV) infection (age at hearing loss diagnosis 0.75 to 204 months, mean 45.6 ± 43.9), while 16 between late-onset SNHL and other congenital or perinatal factors, namely Neonatal Intensive Care Unit (NICU) stay, prematurity, neonatal respiratory failure, mechanical ventilation, extracorporeal membrane oxygenation (ECMO) support, hypocapnia, hypoxia, alkalosis, seizure activity, congenital diaphragmatic hernia (CDH), inner ear malformation, and gene mutations (age at hearing loss diagnosis 2.5 to 156 months, mean 38.7 ± 40.7). CONCLUSIONS: cCMV infection may cause late-onset SNHL, which can be missed on standard NHSP. There is, therefore, evidence to support universal screening programmes to enable detection in even asymptomatic neonates. Ongoing audiological follow-up for all children with cCMV is advisable, to enable timely treatment. In the paediatric population presenting conditions such as NICU stay > 5 days, prematurity ≤ 34 weeks gestation, severe neonatal respiratory failure, mechanical ventilation, ECMO support, and CDH surgery, an audiological follow-up from 3 months of age up to at least 3-4 years of age, and at least annually, should be recommended.

INTRODUCTION: The presence of cervical lymph node metastases is an unfavorable prognostic factor in head and neck squamous cell carcinoma (HNSCC) and a potential cause of treatment failure. Occult lymph node metastasis occurs in approximately 15-20% of HNSCC patients with a clinically negative neck (cN0), greatly impacting on their prognosis. The present study aimed to investigate the role of pre-treatment peripheral blood markers in predicting clinically occult cervical lymph node metastasis. METHODS: This multicenter, retrospective study was performed in a cohort of 472 patients diagnosed with cN0 HNSCC who underwent up-front surgery. Baseline neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic inflammatory marker (SIM), and systemic immune-inflammation index (SII) were calculated from available blood parameters. RESULTS: Oro-hypopharyngeal and oral cancers, locally advanced stage, moderately (G2), and poorly (G3) differentiated grade were associated with an increased risk of pathological lymph node involvement. NLR, LMR, PLR, SIM, and SII were significantly associated at multivariable analysis. NLR >2.12 was the most reliable at predicting occult lymph node metastasis (OR = 5.22; 95% CI: 2.14-12.75). We describe a predictive score integrating cancer site, local stage, and NLR which is effective at predicting positive lymph node pathological status. CONCLUSIONS: The present study provides evidence that pre-treatment peripheral blood markers, in particular NLR, represent reliable predictors of clinically occult cervical lymph node metastasis in cN0 HNSCC. Therefore, the present study provides a novel useful predictive score for directing the elective management of the neck in patients with cN0 HNSCC.

OBJECTIVES: Electrically evoked compound action-potentials (ECAPs) can be recorded using the electrodes in a cochlear implant (CI) and represent the synchronous responses of the electrically stimulated auditory nerve. ECAPs can be obtained using a forward-masking method that measures the neural response to a probe and masker electrode separately and in combination. The panoramic ECAP (PECAP) analyses measured ECAPs obtained using multiple combinations of masker and probe electrodes and uses a nonlinear optimization algorithm to estimate current spread from each electrode and neural health along the cochlea. However, the measurement of ECAPs from multiple combinations of electrodes is too time consuming for use in clinics. Here, we propose and evaluate SpeedCAP, a speedy method for obtaining the PECAP measurements that minimizes recording time by exploiting redundancies between multiple ECAP measures. DESIGN: In the first study, 11 users of Cochlear Ltd. CIs took part. ECAPs were recorded using the forward-masking artifact-cancelation technique at the most comfortable loudness level (MCL) for every combination of masker and probe electrodes for all active electrodes in the users' MAPs, as per the standard PECAP recording paradigm. The same current levels and recording parameters were then used to collect ECAPs in the same users with the SpeedCAP method. The ECAP amplitudes were then compared between the two conditions, as were the corresponding estimates of neural health and current spread calculated using the PECAP method previously described by Garcia et al. The second study measured SpeedCAP intraoperatively in 8 CI patients and with all maskers and probes presented at the same current level to assess feasibility. ECAPs for the subset of conditions where the masker and probe were presented on the same electrode were compared with those obtained using the slower approach leveraged by the standard clinical software. RESULTS: Data collection time was reduced from ≈45 to ≈8 minutes. There were no significant differences between normalized root mean squared error (RMSE) repeatability metrics for post-operative PECAP and SpeedCAP data, nor for the RMSEs calculated between PECAP and SpeedCAP data. The comparison achieved 80% power to detect effect sizes down to 8.2% RMSE. When between-participant differences were removed, both the neural-health (r = 0.73) and current-spread (r = 0.65) estimates were significantly correlated ( p < 0.0001, df = 218) between SpeedCAP and PECAP conditions across all electrodes, and showed RMSE errors of 12.7 ± 4.7% and 16.8 ± 8.8%, respectively (with the ± margins representing 95% confidence intervals). Valid ECAPs were obtained in all patients in the second study, demonstrating intraoperative feasibility of SpeedCAP. No significant differences in RMSEs were detectable between post- and intra-operative ECAP measurements, with the comparison achieving 80% power to detect effect sizes down to 13.3% RMSE. CONCLUSIONS: The improved efficiency of SpeedCAP provides time savings facilitating multi-electrode ECAP recordings in routine clinical practice. SpeedCAP data collection is sufficiently quick to record intraoperatively, and adds no more than 8.2% error to the ECAP amplitudes. Such measurements could thereafter be submitted to models such as PECAP to provide patient-specific patterns of neural activation to inform programming of clinical MAPs and identify causes of poor performance at the electrode-nerve interface of CI users. The speed and accuracy of these measurements also opens up a wide range of additional research questions to be addressed.

PURPOSE: Heterogeneous reporting in baseline variables in patients undergoing transsphenoidal resection of pituitary adenoma precludes meaningful meta-analysis. We therefore examined trends in reported baseline variables, and degree of heterogeneity of reported variables in 30 years of literature. METHODS: A systematic review of PubMed and Embase was conducted on studies that reported outcomes for transsphenoidal surgery for pituitary adenoma 1990-2021. The protocol was registered a priori and adhered to the PRISMA statement. Full-text studies in English with > 10 patients (prospective), > 500 patients (retrospective), or randomised trials were included. RESULTS: 178 studies were included, comprising 427,659 patients: 52 retrospective (29%); 118 prospective (66%); 9 randomised controlled trials (5%). The majority of studies were published in the last 10 years (71%) and originated from North America (38%). Most studies described patient demographics, such as age (165 studies, 93%) and sex (164 studies, 92%). Ethnicity (24%) and co-morbidities (25%) were less frequently reported. Clinical baseline variables included endocrine (60%), ophthalmic (34%), nasal (7%), and cognitive (5%). Preoperative radiological variables were described in 132 studies (74%). MRI alone was the most utilised imaging modality (67%). Further specific radiological baseline variables included: tumour diameter (52 studies, 39%); tumour volume (28 studies, 21%); cavernous sinus invasion (53 studies, 40%); Wilson Hardy grade (25 studies, 19%); Knosp grade (36 studies, 27%). CONCLUSIONS: There is heterogeneity in the reporting of baseline variables in patients undergoing transsphenoidal surgery for pituitary adenoma. This review supports the need to develop a common data element to facilitate meaningful comparative research, trial design, and reduce research inefficiency.

BACKGROUND: Despite alterations in the sense of smell and taste have dominated the symptoms of SARS-CoV-2 infection, the prevalence and the severity of self-reporting COVID-19 associated olfactory and gustatory dysfunction has dropped significantly with the advent of the Omicron BA.1 subvariant. However, data on the evolution of Omicron-related chemosensory impairment are still lacking. OBJECTIVE: The aim of the present study was to estimate the prevalence and the recovery rate of self-reported chemosensory dysfunction 6-month after SARS-CoV-2 infection acquired during the predominance of the Omicron BA.1 subvariant in Italy. METHODS: Prospective observational study based on the sino-nasal outcome tool 22 (SNOT-22), item "sense of smell or taste" and additional outcomes conducted in University hospitals and tertiary referral centers in Italy. RESULTS: Of 338 patients with mild-to-moderate COVID-19 completing the baseline survey, 294 (87.0 %) responded to the 6-month follow-up interview. Among them, 101 (34.4 %) and 4 (1.4 %) reported an altered sense of smell or taste at baseline and at 6 months, respectively. Among the 101 patients with COVID-19-associated smell or taste dysfunction during the acute phase of the disease, 97 (96.0 %) reported complete resolution at 6 months. The duration of smell or taste impairment was significantly shorter in vaccinated patients (p = 0.007). CONCLUSIONS: Compared with that observed in subjects infected during the first wave of the pandemic, the recovery rate from chemosensory dysfunctions reported in the present series of patients infected during the predominance of the Omicron BA.1 subvariant was more favorable with a shorter duration being positively influenced by vaccination.

AIMS: To assess all available data and determine the success rates and tolerability of local anaesthetic myringoplasty in comparison with those undertaken under general anaesthetic myringoplasty. MATERIALS AND METHODS: The study was designed following a PRISMA-P protocol and registered with the PROSPERO database. MEDLINE, Cochrane Library (CDSR/Central), EMBASE and CINHAL-were directly searched for studies, which met the inclusion criteria. OBJECTIVES: Primary objective was to compare perforation closure rates between patients undergoing myringoplasty under local anaesthetic and those under general anaesthetic from all available published data. Secondary outcomes include complications, such as 'any minor complications', infection rates in the first 6 month post-op, facial nerve weakness, dysgeusia and patient satisfaction. RESULTS: 27 studies were included in the final analysis and found that myringoplasty had an overall perforation closure rate of 89%. The pooled proportion of closures after myringoplasty under local anesthesia was 87% and for myringoplasties under general anesthesia was 91%. Analysis of myringoplasty under local anaesthesia focusing on 'in-office' performed procedures only, found a closure rate of 88%. CONCLUSIONS: There is no significant difference in the success rate of myringoplasty surgery when performed under local or general anaesthetic as measured by perforation closure rates. However, there are other factors, which can drive choosing local anaesthetic surgery, such as minimising anaesthetic risks, reducing costs and reducing environmental impact.

OBJECTIVES OF REVIEW: To review the literature for the evidence base for the aetiology and management of referred otalgia, looking particularly at non-malignant, neuralgic, structural and functional issues. TYPE OF REVIEW: Systematic review. SEARCH STRATEGY: A systematic literature search was undertaken from the databases of EMBASE, CINAHL, MEDLINE®, BNI, and Cochrane Library according to predefined inclusion and exclusion criteria. EVALUATION METHOD: All relevant titles, abstracts and full text articles were reviewed by three authors who resolved any differences by discussion and consultation with senior author. RESULTS: 44 articles were included in our review. The overall quality of evidence was low, with the vast majority of the studies being case-series with three cohort and four randomised-controlled trials included. The prime causes and management strategies were focussed on temporomandibular joint dysfunction (TMJD), Eagle syndrome and neuralgia. Our meta-analyses found no difference on the management strategies for the interventions found. CONCLUSIONS: Referred otalgia is common and treatment should be aimed at the underlying pathology. Potential aetiologies are vast given the extensive sensory innervation of the ear. An understanding of this and a structured approach to patient assessment is important for optimal patient management.

INTRODUCTION: No studies have reported data on 3-year prevalence and recovery rates of self-reported COVID-19-related olfactory and gustatory dysfunction. The aim of the present study was to estimate the 3-year prevalence and recovery rate of self-reported COVID-19-related chemosensory dysfunction in a cohort of patients with antecedent mild COVID-19. METHODS: This is a prospective observational study, measuring the prevalence of altered sense of smell or taste at follow-up and their variation from baseline, on adult patients consecutively assessed at Treviso and Trieste University Hospitals, who tested positive for SARS-CoV-2 RNA by polymerase chain reaction during March 2020. RESULTS: Overall, out of 403 respondents, 267 patients (66.3%) reported an altered sense of smell or taste (SNOT-22 > 0) at baseline, while 56 (13.9%), 29 (7.2%), and 21 (5.2%) reported such alterations at 6-24 months, 2 years, and 3 years, respectively. Among the 267 patients with COVID-19-associated smell or taste dysfunction at baseline, 246 (92.1%) reported complete resolution at 3 years. Of the patients who still experienced smell or taste dysfunction 2 years after COVID-19, 27.6% and 37.9% recovered completely and partially, respectively, at the 3-year follow-up. CONCLUSION: Among subjects with antecedent mildly symptomatic SARS-CoV-2 infection, the 3-year prevalence and recovery rate of COVID-19-related alteration in sense of smell or taste was 5% and 92%, respectively. In approximately two-thirds of patients experiencing chemosensory dysfunction still 2 years after COVID-19, it is still possible to observe a delayed complete or partial recovery after a period of 3 years, while the remaining one-third of individuals continues to have unchanged persistent chemosensory alteration.

BACKGROUND: Otitis externa is a condition causing inflammation of the outer ear canal, which presents with itching, discharge and pain. Most cases of acute otitis externa are caused by bacterial infection and are thus treated with antibiotics. This systematic review and meta-analysis of randomised controlled trials aims to assess the effectiveness of topical non-antibiotic treatments compared to topical antibiotic treatment for the treatment of acute otitis externa. METHODS: Systematic review and meta-analysis databases searched: Cochrane Library including ClinicalTrials.gov; MEDLINE; World Health Organisation International Clinical Trials Registry Platform and Web of Science to identify randomised clinical trials evaluating topical antibiotics and topical non-antibiotic agents in adults and children with acute otitis externa. Non-antibiotic therapeutics for comparison with topical antibiotics included antiseptics, steroids, non-pharmaceuticals and astringents. RESULTS: Seventeen trials were eligible for inclusion, with 10 combined in meta-analysis. Data could be pooled comparing antiseptic and steroid monotherapies with topical antibiotic agents. There were no significant differences in cure rates in any pairwise comparisons. Individually, the majority of studies favoured topical antiseptics or steroids over antibiotics, however these differences were not significant when pooled in meta-analysis. CONCLUSION: Antiseptic, steroid and antibiotic monotherapies are all effective for the management of acute otitis externa. There is insufficient evidence to suggest that topical antiseptic or steroid agents are superior or inferior to topical antibiotics.

OBJECTIVE: Review the effectiveness of surgical and non-surgical management strategies for isolated pars flaccida and combined pars tensa and flaccida tympanic membrane retractions in preventing progression or recurrence, improving hearing and preventing development of cholesteatoma. DESIGN: Narrative review. SETTING: ENT and otology services worldwide. PARTICIPANTS: Patients with non-cholesteatoma tympanic membrane retractions. MAIN OUCTOME MEASURE: Changes in retraction (progression or resolution, or development of a known sequela such as perforation). RESULTS: Eight full text papers are included: three randomised controlled trials and five case series or cohort studies of more than five patients (a total of 238 ears). Data exists for the use of conservative management, ventilation tubes, laser tympanoplasty, cartilage and fascia tympanoplasty, lateral attic reconstruction as well as mastoid procedures. CONCLUSION: Few high-quality studies on the management of isolated and combined pars flaccida retractions exist. For isolated pars flaccida retractions deemed to require surgical intervention, this review suggests that lateral attic reconstruction and cartilage tympanoplasty carries least risk of recurrence.
ABSTRACT
OBJECTIVES: To estimate the prevalence of, and risk factors associated with electrode migration (EM) in cochlear implant (CI) recipients. DESIGN: Historical cohort study of all CIs performed between 1 January 2018 and 1 August 2021 in a single tertiary adult and paediatric CI centre in the UK. MAIN OUTCOME MEASURES: The primary aim is to determine the prevalence of electrode migration, comparing intraoperative surgeon report and examination of a routine plain radiograph performed 2 weeks after surgery. EM is defined as the detection of movement of two or more electrodes out of the cochlea from the time of surgery. Multivariate analysis was performed to investigate preoperative and intraoperative risk factors that might predispose to migration. RESULTS: Four hundred and sixty-five patients, having 516 distinct surgeries, with 628 implants were analysed. EM occurred following 11.5% of implant operations. Pre-existing cochlear abnormality was an independent associated risk factor for EM (OR: 3.40 ⟨1.20-9.62⟩ p = .021). Demographics, surgical technique, usage of a precurved electrode, CSF leak, surgeon seniority and intraoperative telemetry did not influence risk of migration. There were 5 implants (0.8%) which migrated later than 2 weeks, with a median date of imaging diagnosis (x-ray or CT scan) of 263 days ⟨IQR:198⟩, for which head injury was a common precipitating factor. There were differences in the risk of migration between different lateral wall electrodes. CONCLUSION: EM in the early postoperative period is a common occurrence and is more likely in implant recipients with obstructed or malformed cochleae.

BACKGROUND: Inflammatory blood markers have been associated with oncological outcomes in several cancers, but evidence for head and neck squamous cell carcinoma (HNSCC) is scanty. Therefore, this study aims at investigating the association between five different inflammatory blood markers and several oncological outcomes. METHODS: This multi-centre retrospective analysis included 925 consecutive patients with primary HPV-negative HNSCC (median age: 68 years) diagnosed between April 2004 and June 2018, whose pre-treatment blood parameters were available. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), systemic inflammatory marker (SIM), and systemic immune-inflammation index (SII) were calculated; their associations with local, regional, and distant failure, disease-free survival (DFS), and overall survival (OS) was calculated. RESULTS: The median follow-up was 53 months. All five indexes were significantly associated with OS; the highest accuracy in predicting patients' survival was found for SIM (10-year OS = 53.2% for SIM < 1.40 and 40.9% for SIM ≥ 2.46; c-index = 0.569) and LMR (10-year OS = 60.4% for LMR ≥ 3.76 and 40.5% for LMR < 2.92; c-index = 0.568). While LMR showed the strongest association with local failure (HR = 2.16; 95% CI:1.22-3.84), PLR showed the strongest association with regional (HR = 1.98; 95% CI:1.24-3.15) and distant failure (HR = 1.67; 95% CI:1.08-2.58). CONCLUSION: Different inflammatory blood markers may be useful to identify patients at risk of local, regional, or distant recurrences who may benefit from treatment intensification or intensive surveillance programs.

INTRODUCTION: The prevalence of hearing loss and its consequences is increasing as the elderly population grows. As the guidelines for cochlear implantation (CI) expand, the number of elderly CI recipients is also increasing. We report complication rates, survival duration, and audiological outcomes for CI recipients aged 80 years and over and discuss the cost utility of CI in this age group. METHODS: A retrospective cohort study was undertaken of all CI recipients (126 cases), aged 80 years and over at the time of their surgery, implanted at our institution (Cambridge University Hospitals) during a period from January 1, 2001, to March 31, 2019. Data on survival at 1, 3, and 5 years post-implantation, post-operative complications and functional hearing outcomes including audiometric and speech discrimination outcomes (Bamford-Kowal-Bench sentence test) have been reported. RESULTS: The mean age at implantation was 84 years. The mean audiometric score improved from 108 dB HL to 28 dB HL post-implantation. The mean Bamford-Kowal-Bench score improved from 14% to 66% and 73% at 2 and 12 months post-implantation, respectively. The complication rate was 15.3%. The survival probability at 1 year post-implantation was 0.95 for females and 0.93 for males, at 3 years was 0.89 for females and 0.81 for males, and at 5 years was 0.74 for females and 0.54 for males. CONCLUSION: CI is safe and well-tolerated in this age group and elderly patients gain similar audiometric and functional benefit as found for younger age groups.

PURPOSE: Primary: To determine the rate of occult cervical metastases in primary temporal bone squamous cell carcinomas (TBSSC). Secondary: to perform a subgroup meta-analysis of the risk of occult metastases based on the clinical stage of the tumour and its risk based on corresponding levels of the neck. METHODS: A systematic review and meta-analysis of papers searched through Medline, Cochrane, Embase, Scopus and Web of Science up to November 2021 to determine the pooled rate of occult lymph node/parotid metastases. Quality assessment of the included studies was assessed through the Newcastle-Ottawa scale. RESULTS: Overall, 13 out of 3301 screened studies met the inclusion criteria, for a total of 1120 patients of which 550 had TBSCC. Out of the 267 patients who underwent a neck dissection, 33 had positive lymph nodes giving a pooled rate of occult metastases of 14% (95% CI 10-19%). Occult metastases rate varied according to Modified Pittsburg staging system, being 0% (0-16%) among 12 pT1, 7% (2-20%) among 43 pT2 cases, 21% (11-38%) among 45 pT3, and 18% (11-27%) among 102 pT4 cases. Data available showed that most of the positive nodes were in Level II. CONCLUSION: The rate of occult cervical metastases in TBSCC increases with pathological T category with majority of nodal disease found in level II of the neck.

PURPOSE: The aim of the present study was to estimate the 1 year prevalence and recovery rate of self-reported chemosensory dysfunction in a series of subjects with previous mild-to-moderate symptomatic COVID-19. METHODS: Prospective study based on the SNOT-22, item "sense of smell or taste" and additional outcomes. RESULTS: 268/315 patients (85.1%) completing the survey at baseline also completed the follow-up interview. The 12 months prevalence of self-reported COVID-19 associated chemosensory dysfunction was 21.3% (95% CI 16.5-26.7%). Of the 187 patients who complained of COVID-19 associated chemosensory dysfunction at baseline, 130 (69.5%; 95% CI 62.4-76.0%) reported complete resolution of smell or taste impairment, 41 (21.9%) reported a decrease in the severity, and 16 (8.6%) reported the symptom was unchanged or worse 1 year after onset. The risk of persistence was higher for patients reporting a baseline SNOT-22 score ≥ 4 (OR = 3.32; 95% CI 1.32-8.36) as well as for those requiring ≥ 22 days for a negative swab (OR = 2.18; 95% CI 1.12-4.27). CONCLUSION: A substantial proportion of patients with previous mild-to-moderate symptomatic COVID-19 characterized by new onset of chemosensory dysfunction still complained on altered sense of smell or taste 1 year after the onset.

OBJECTIVES: To report the experience of civilian penetrating neck trauma (PNT) at a UK level I trauma centre, propose an initial management algorithm and assess the degree of correlation between clinical signs of injury, operative findings and radiological reports. DESIGN: Retrospective case note review. SETTING: UK level I trauma centre April 2012-November 2017. PARTICIPANTS: Three hundred ten cases of PNT were drawn from electronic patient records. Data were extracted on hard and soft signs of vascular or aerodigestive tract injury, clinical management, radiological imaging and patient outcomes. MAIN OUTCOME MEASURES: Patient demographics, mechanism of injury, morbidity and mortality. The correlation between clinical signs, and radiological reports to internal injury on surgical exploration. RESULTS: Two hundred seventy-one (87.4%) male and 39 (13.6%) female patients with a mean age of 36 years (16-87) were identified. The most common causes of injury were assault 171 (55.2%) and deliberate self-harm 118 (38%). A knife was the most common instrument 240 (77.4%). Past psychiatric history was noted in 119 (38.4%), and 60 (19.4%) were intoxicated. 50% were definitively managed in theatre with a negative exploration rate of 38%, and 50% were managed in ED. Pre-operative radiological reports correlated with operative reports in 62% of cases with venous injury the most common positive and negative finding. Multivariate correlation was r = 0.89, p = 0.045, between hard signs plus positive radiology findings and internal injury on neck exploration. CONCLUSIONS: Management of PNT by clinical and radiological signs is safe and effective, and can be streamlined by a decision-making algorithm as proposed here.

This study prospectively assessed the 6-month prevalence of self-reported and psychophysically measured olfactory dysfunction in subjects with mild-to-moderate COVID-19. Self-reported smell or taste impairment was prospectively evaluated by SNOT-22 at diagnosis, 4-week, 8-week, and 6-month. At 6 months from the diagnosis, psychophysical evaluation of olfactory function was also performed using the 34-item culturally adapted University of Pennsylvania Smell Identification Test (CA-UPSIT). 145 completed both the 6-month subjective and psychophysical olfactory evaluation. According to CA-UPSIT, 87 subjects (60.0%) exhibited some smell dysfunction, with 10 patients being anosmic (6.9%) and seven being severely microsmic (4.8%). At the time CA-UPSIT was administered, a weak correlation was observed between the self-reported alteration of the sense of smell or taste and olfactory test scores (Spearman's r = -0.26). Among 112 patients who self-reported normal sense of smell at last follow-up, CA-UPSIT revealed normal smell in 46 (41.1%), mild microsmia in 46 (41.1%), moderate microsmia in 11 (9.8%), severe microsmia in 3 (2.3%), and anosmia in 6 (5.4%) patients; however, of those patients self-reporting normal smell but who were found to have hypofunction on testing, 62 out of 66 had a self-reported reduction in sense of smell or taste at an earlier time point. Despite most patients report a subjectively normal sense of smell, we observed a high percentage of persistent smell dysfunction at 6 months from the diagnosis of syndrome coronavirus 2 (SARS-CoV-2) infection, with 11.7% of patients being anosmic or severely microsmic. These data highlight a significant long-term rate of smell alteration in patients with previous SARS-COV-2 infection.

BACKGROUND: Over 50% of patients with head-and-neck squamous cell carcinoma (HNSCC) experience locoregional recurrence, which is associated with poor outcome. In the course of follow-up for patients surviving primary surgery for HNSCC, one might ask: What is the probability of recurrence in one year considering that the cancer has not yet recurred to date? MATERIALS AND METHODS: To answer this question, 979 patients surgically treated for HNSCC (i.e. cancer of the oral cavity, oropharynx, hypopharynx or larynx) between March 2004 and June 2018 were enrolled in a multicenter retrospective cohort study, followed up for death and recurrence over a 5 year period. The conditional probability of recurrence in 12 months - i.e. the probability of recurrence in the next 12 months given that, to date, the patient has not recurred - was derived from the cumulative incidence function (Aalen-Johansen method). RESULTS: Overall, the probability of recurrence was the highest during the first (17.3%) and the second years (9.6%) after surgery, declining thereafter to less than 5.0% a year thereafter. The probability of recurrence was significantly higher for stage III-IV HNSCCs than for stage I-II HNSCCs in the first year after surgery (20.4% versus 10.0%; p < 0.01), but not thereafter. This difference was most pronounced for oral cavity cancers. No significant differences were observed across different tumor sites. CONCLUSION: This dynamic evaluation of recurrence risk in patients surgically treated for HNSCC provides helpful and clinically meaningful information, which can be useful to patients in planning their future life, and to clinicians in tailoring post-treatment surveillance according to a more personalized risk stratification.

During the last decade, the worldwide incidence of keratinocyte carcinomas (KC) has increased significantly. They are now the most common malignancy, representing approximately 30% of all cancers. The role of ultraviolet (UV) radiation as a major environmental risk factor for skin cancers is well recognized. The aim of this review is to analyse the current understanding of the nature of beta-human papillomavirus (HPV) and its association with KC and explore the implications for the management and prevention of these cancers. A comprehensive review of the literature on beta-HPV and its association with KC was undertaken, the results reported in the form of a narrative review. A subgroup of HPV that infects the mucosal epithelia of the genital tract has been firmly associated with carcinogenesis. In addition, some HPV types with cutaneous tropism have been proposed to cooperate with UV in the development of KC. The first evidence for this association was reported in 1922 in patients with epidermodysplasia verruciformis (EV). Since then, epidemiological studies have highlighted the higher risk of skin cancer in patients with EV and certain cutaneous HPV types, and in vitro studies have elucidated molecular mechanisms and transforming properties of beta-HPV. Furthermore, in vivo research conducted on transgenic mice models has shown the possible role of beta-HPV in cutaneous carcinogenesis as a co-factor with UV radiation and immunosuppression. There is good evidence supporting the role of beta-HPV in the oncogenesis of KC. The high prevalence of beta-HPV in human skin and the worldwide burden of KC makes the search for an effective vaccine relevant and worthwhile.
