Purpose To estimate the prevalence of smell or taste impairment in household contacts of mildly symptomatic home-isolated SARS-CoV-2 positive patients.Methods Cross sectional study based on ad hoc questions.Results Of 214 mildly symptomatic COVID-19 patients managed at home under self-isolation, 179 reported to have at least one household contact, with the total number of no study participants contacts being 296. Among 175 household contacts not tested for SARS-CoV-2 infection, 67 (38.3%) had SARS-CoV-2 compatible symptoms, 39 (22.3%) had loss of smell or taste with 7 (4.0%) having loss of smell or taste in the absence of other symptoms. The prevalence of smell or taste impairment was 1.5% in patients tested negative compared to 63.0% of those tested positive for SARS-CoV-2 (pConclusion Smell or taste impairment are quite common in not-tested household contacts of mildly symptomatic home-isolated SARS-CoV-2 positive patients. This should be taken into account when estimating the burden of loss of sense of smell and taste during COVID-19 pandemic, and further highlights the value of loss of sense of smell and taste as a marker of infection.

The aim of this study was to assess whether the chronic preoperative administration of intranasal corticosteroids (INCs) in chronic rhinosinusitis with/without nasal polyposis (CRSwNP/CRSsNP, respectively) could significantly influence bleeding during functional endoscopic sinus surgery (FESS). We prospectively enrolled 109 patients (56 CRSwNP and 53 CRSsNP) candidate for FESS who underwent clinical evaluation and anamnestic data collection. They were allocated to 2 groups depending on whether or not they were chronic INC users, as declared at their first medical evaluation: chronic “INC users” represented the treated group, while “INC nonusers” formed the control group. Lund-Mackay and American Society of Anesthesiology (ASA) scores, blood loss expressed both in milliliters and using the Boezaart scale, operation time in minutes, pre- and postoperative 22-item Sino Nasal Outcome Scores (SNOT-22) were collected. Each sample underwent histopathological evaluation. The results showed that anamnestic information, Lund-Mackay, and SNOT-22 scores were similar between the 2 groups ( P > .05). The average blood loss expressed in milliliters and operative time were slightly, but not significantly, higher in the INC user group, while the Boezaart scores proved significantly higher in the INC users ( P = .038). No differences emerged between CRSwNP and CRSsNP within each group in terms of bleeding. The pathologist described common features in the majority (78%) of INC group samples: ectatic venules embedded in a fibrous stroma and hypertrophy of the arterial muscular layer. In our experience, despite the presence of NP, chronic preoperative administration of INCs was associated with increased intraoperative bleeding according the Boezaart scale although objective recordings of blood loss were not statistically different between the INC users and nonusers.

Background To enforce the evidence for causality between high-risk human papillomavirus (hrHPV) infections and neck squamous cell carcinoma from unknown primary (NSCCUP) and provide biological basis for treatment de-intensification, we searched for TP53 mutations in association with HPV status. Methods TP53 mutations were searched for by amplification of exons 4 to 10. Results Of the 70 NSCCUP, 27 (39%) harbored HPV infection. TP53 sequencing resulted in the identification of 19 patients harboring single mutations including 16 disruptive alterations (84%). The association of TP53 mutations and HPV could be evaluated in 48 NSCCUP including those with disruptive mutation in any exon (n = 16) and those without mutations but with complete sequence of exons 4 to 9 (n = 32): no disruptive mutations were found in the 17 HPV-driven NSCCUP but in 16 of the 31 non-HPV-driven NSCCUP (P = .0002). Conclusion In a fraction of cases, NSCCUP is an HPV-driven entity harboring wild-type TP53 gene or nondisruptive TP53 mutations. HPV-driven NSCCUP might benefit from treatment de-intensification.

Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection can cause a wide array of symptoms ranging from mild to severe or fatal forms of coronavirus disease 2019 (COVID-19). Furthermore, it has been observed that in a proportion of patients a variable range of symptoms may persist for a long time. An increasing number of studies have been focused on long COVID, but they have mainly been concentrated on previously hospitalized severe COVID-19 patients reporting symptoms up to 6-months after illness. The main aim of this study was to evaluate the prevalence of COVID-related symptoms 12-months after the onset of mild-to-moderate disease.

Objectives/Hypothesis: To assess the disease control, survival rates, and prognostic factors of exclusive surgical treatment for patients with pT3 N0 laryngeal squamous cell carcinoma (LSCC). Study Design: Multicentric retrospective cohort study. Methods: Multicentric retrospective case series of previously untreated patients with pT3 R0N0 LSCC, who received exclusive surgery between 2011 and 2019. Tumor location; subsite involvement; grading; and lymphatic, vascular, and perineural invasion were reported. Overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were measured. Results: Fifty-four patients (mean age 67.1; male sex 83.3%; mean follow-up period 37 months) underwent total laryngectomy (48.1%) or partial laryngectomy (51.9%). Ipsilateral or bilateral neck dissection was performed in 46 (85.2%) cases. Perineural invasion was more frequent in case of supraglottic involvement than glottic involvement (85.7% vs. 14.3%, P=.03). Five (9.3%) patients experienced recurrence (3 local recurrences, 1 nodal recurrence, 1 distant recurrence). Rate of recurrence differed between glottic (0%), supraglottic (80%), and transglottic (20%) tumors (P=.01), with a lower risk yielded by glottic involvement (odds ratio [OR], 0.05, 95% confidence interval [95% CI], 0.01–0.56, P=.01). A higher risk was recorded in case of perineural invasion (OR, 66.0, 95% CI, 1.41–3085.3, P=.03). The OS, DSS, and DFS were 79.6%, 96.3%, and 90.7%, without differences regarding the type of surgery. The DFS was lower in case of supraglottic involvement when compared to purely glottic LSCC (83.9% vs. 100%, P=0.02). Conclusions: Exclusive surgery is a safe option for patients with pT3 R0N0 LSCC. Adjuvant treatments or closer follow-up monitoring might be considered in case of supraglottic involvement or perineural invasion. Level of Evidence: 4 Laryngoscope, 131:2262–2268, 2021.

Introduction After surgery for oral cavity cancer, superficial surgical defects are usually covered with a skin graft that can be harvested with different thicknesses depending on the reconstructive need. Despite its popularity and efficacy, this solution has the disadvantage of excessive harvesting times and scarring of the donor site. Other surgeons have proposed the use of bovine pericardium as a reconstructive solution. Its use in otorhinolaryngology especially after oral cavity surgery has never been reported. Objective The aim of this manuscript is to present our preliminary experience with the use of a collagen membrane obtained from bovine pericardium in the reconstruction of small and superficial defects after transoral resection of oral cavity tumors. Methods A bovine collagen membrane was used to cover surgical defects in 19 consecutive patients undergoing transoral resection of small/superficial oral cancers. Photographs were obtained in the postoperative period to follow the healing process. We analyzed the pro and cons of this tool, recorded data on postoperative chewing-, speech- and taste-related quality of life, and tested the most appropriate settings providing the best reconstructive result. Results The bovine collagen membrane allowed us to cover surgical defects of varying size in different oral sites. Shaping and placement proved to be simple. The membrane facilitated physiologic tissue repair: after one month it was completely absorbed and replaced by the patient’s own mucosa. No adverse features were observed in the cohort. Conclusion A bovine collagen membrane can represent a fast and easy solution in cases of split-thickness defect. Unlike a skin graft, it is not associated with donor site morbidity and allows the patient’s own mucosa to be restored with a more physiological result.

Objective: To estimate the prevalence of metastasis in the perimarginal nodes (PMNs) (also known as perifacial, preglandular and retroglandual nodes) in head and neck cancer. Methods: We recruited 136 patients affected by cancers of the oral cavity, lip, oropharynx, skin and by cáncer of unknown primary (CUP), who were candidates for level IB dissection. PMNs were identified and sent separately for histological analysis. Correlation between metastasis to the PMNs and characteristics of the primary tumour were reported. Results: The incidence of metastasis was 17% from oral cancer, 50% from lip cancer and 12.5% from skin cancer. No metastases were reported for oropharynx cancer or CUP. The only factor that correlated with the incidence of metastases was origin of the tumour from the upper part of oral cavity. Conclusion: PMNs represent a frequent site of metastasis in oral and lip cancers. In cancer of the oropharynx, their involvement has not been not reported, while their role in skin cancers remains to be clarified.

Purpose: Narrow band imaging (NBI) enhances mucosal vasculature and could help in the identification of recurrences. We assessed the effectiveness of NBI with flexible video-endoscope in the early detection of recurrence after treatment of head and neck squamous cell carcinoma, its diagnostic advantage over high-definition white-light (HD WL) endoscopy, also in relation to recurrence site, and the influence of previous radiotherapy (RT) or chemotherapy (CT). Moreover, we investigated the association between index tumor site and the risk of developing recurrence, and the relation between index tumor site and recurrence site. Methods: From January 2018 to November 2020, 160 patients previously treated with surgery and/or RT ± CT were evaluated using NBI with flexible video-endoscope. Sensitivity, specificity, positive/negative predictive value, and accuracy were calculated for NBI and HD WL, and compared using the McNemar test. The Fisher exact test was used to compare the other associations investigated. Results: The difference between NBI and HD WL sensitivity was statistically significant (p < 0.001). The NBI diagnostic advantage was 62.5%, highest in the hypopharynx (p = 0.05), and was not influenced by previous RT or CT (p = 0.49). Index tumor site statistically related with recurrence site (p < 0.001), but not with the risk of developing recurrence (p = 0.81). Conclusion: NBI with flexible video-endoscope could represent a valid option to detect recurrence early during the follow-up, especially in a difficult-to-visualize site such as the hypopharynx.

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.

ObjectiveTo date, no useful prognostic biomarker exists for patients with oral squamous cell carcinoma (OCSCC), a tumour with uncertain biological behaviour and subsequent unpredictable clinical course. We aim to investigate the prognostic significance of two recurrent somatic mutations (-124 C>T and -146 C>T) within the promoter of telomerase reverse transcriptase (TERT) gene and the impact of TERT single nucleotide polymorphism (SNP) rs2853669 in patients surgically treated for OCSCC.MethodsThe genetic frequencies of rs2853669, -124 C>T and -146 C>T as well as the telomere length were investigated in 144 tumours and 57 normal adjacent mucosal (AM) specimens from OCSCC patients.ResultsForty-five tumours harboured TERT promoter mutations (31.3%), with -124 C>T and -146 C>T accounting for 64.4% and 35.6% of the alterations respectively. Patients with -124 C>T TERT promoter mutated tumours had the shortest telomeres in the AM (p=0.016) and showed higher risk of local recurrence (hazard ratio [HR]:2.75, p=0.0143), death (HR:2.71, p=0.0079) and disease progression (HR:2.71, p=0.0024) with the effect being potentiated by the co-occurrence of T/T genotype of rs2853669.Conclusion-124 C>T TERT promoter mutation as well as the T/T genotype of the rs2853669 SNP are attractive independent prognostic biomarkers in patients surgically treated for OCSCC, with the coexistence of these genetic variants showing a synergistic impact on the aggressiveness of the disease.

Background: Using an age and gender matched-pair case-control study, we aimed to estimate the long-term prevalence of psychophysical olfactory, gustatory , and chemesthesis impairment at least one year after SARS-CoV-2 infection considering the background of chemosensory dysfunction in non-COVID-19 population. Methodology: This case-controlled study included 100 patients who were home-isolated for mildly symptomatic COVID-19 between March and April 2020. One control regularly tested for SARS-CoV-2 infection and always tested negative was matched to each case according to gender and age. Chemosensory function was investigated by a comprehensive psychophysical evaluation including ortho- and retronasal olfaction and an extensive assessment of gustatory function. Differences in chemosensory parameters were evaluated through either Fisher’s exact test or Kruskal-Wallis test. Results: The psychophysical assessment of chemosensory function took place after a median of 401 days from the first SARS-CoV-2 positive swab. The evaluation of orthonasal smell identified 46% and 10% of cases and controls, respectively, having olfactory dysfunction, with 7% of COVID-19 cases being functionally anosmic. Testing of gustatory function revealed a 27% of cases versus 10% of controls showing a gustatory impairment. Nasal trigeminal sensitivity was significantly lower in cases compared to controls. Persistent chemosensory impairment was associated with emotional distress and depression. Conclusion: More than one year after the onset of COVID-19, cases exhibited an excess of olfactory, gustatory , and chemesthesis disturbances compared to matched-pair controls with these symptoms being associated to emotional distress and depression.

In head and neck surgery, sealant films represent a useful adjunct to ensure a reinforcement preventing leakages, dehiscence or oozing. The aim of this pilot study is to present the potential applications of a new sealant sheet in head and neck surgery, reporting outcomes, advantages and limitations. The sample included 32 patients, that underwent oncologic or elective surgery between January 2019 and January 2021 at the Cattinara Hospital in Trieste, Italy. Data regarding the patient, the surgical procedure and the postoperative course over hospitalization in terms of surgical complications were retrospectively collected. In this study, nor complication during the regular follow-up period occurred neither difficulties emerged in TP use in any head and neck subsites. In our experience, TP represented a valid aid in suture strengthening, easy to apply and suitable also for oncologic surgery in which the closure of some surgical defects may need a greater sealing effect.

BackgroundImmunoglobulin G4 related disease is a recently described systemic syndrome. The head and neck region is the second most common site for presentation after the pancreas.MethodsPubMed and the Cochrane Library were searched from 1995 to July 2017 for all the studies on immunoglobulin G4 related disease diagnosed in the head and neck compartment. Patient-specific data were extracted and basic statistical analysis was performed.ResultsNinety-one patients were identified. Treatment was specified in 76 patients. Twenty patients received surgical treatment, eight of them in association with medical therapy. Fifty-six patients received medical treatment. The disease recurred in 25 per cent of patients treated with surgical treatment alone, in 3.6 per cent of patients treated with medical treatment alone and in 12.5 per cent of patients treated with both. All medical treatment protocols contained high-dose corticosteroids.ConclusionEarly and correct diagnosis can avoid unnecessary surgical treatment, and glucocorticoid therapy can improve the long-term prognosis.

Objective Mean corpuscular volume (MCV) has been shown in to be a reliable prognostic marker in other cancers; however, no evidence exists on its use in head and neck squamous cell carcinoma (HNSCC). This study aimed to investigate the association between MCV, hemoglobin, platelet count and albumin concentration, and survival in stage III/IVA-B HNSCC treated with concurrent chemoradiotherapy. Study design Retrospective cohort study. Methods In this multicenter retrospective study, we analyzed MCV, platelet count, hemoglobin concentration, and albumin concentration in peripheral blood samples from 260 patients with HNSCC undergoing organ preservation treatment with curative intent at the time of diagnosis. We then analyzed survival outcomes after accounting for confounders using multivariate analysis. Results After adjustment for potential confounders, patients with low hemoglobin had a 3.3-fold higher risk of death (95% confidence interval [CI]: 2.26-4.81) than those with normal hemoglobin. Patients with an elevated MCV had a 1.54-fold higher risk of death (95% CI: 1.06-2.24), independent of site, stage, and human papillomavirus status. Interestingly, the effect of MCV on overall and progression-free survival was limited to those with a normal pretreatment hemoglobin. We identified no associations between pretreatment platelet count or albumin concentration and survival. Conclusion These findings suggest that pretreatment anemia and macrocytosis are independent predictors of lower overall and progression-free survival in HNSCC patients undergoing organ preservation treatment.

Funder: Università degli Studi di Trieste, PURPOSE: The aim of this study is to evaluate the prognostic value of pre-treatment advanced lung cancer inflammation index (ALI) in patients with HPV-negative HNSCC undergoing up-front surgical treatment. METHODS: The present multi-centre, retrospective study was performed in a consecutive cohort of patients who underwent upfront surgery with or without adjuvant (chemo)-radiotherapy for head and neck squamous cell carcinoma (HNSCC). Patients were stratified by ALI, and survival outcomes were compared between groups. In addition, the prognostic value of ALI was compared with two other indices, the prognostic nutritional index (PNI) and systemic inflammatory index (SIM). RESULTS: Two hundred twenty-three patients met the inclusion criteria (151 male and 72 female). Overall and progression-free survival were significantly predicted by ALI < 20.4 (HR 3.23, CI 1.51-6.90 for PFS and HR 3.41, CI 1.47-7.91 for OS). Similarly, PNI < 40.5 (HR = 2.43, 95% CI: 1.31-4.51 for PFS and HR = 2.40, 95% CI: 1.19-4.82 for OS) and SIM > 2.5 (HR = 2.51, 95% CI: 1.23-5.10 for PFS and HR = 2.60, 95% CI: 1.19-5.67 for OS) were found to be significant predictors. Among the three indices, ALI < 20.4 identified the patients with the worst 5-year outcomes. Moreover, patients with a combination of low PNI and low ALI resulted to be a better predictor of progression (HR = 5.26, 95% CI: 2.01-13.73) and death (HR = 5.68, 95% CI: 1.92-16.79) than low ALI and low PNI considered alone. CONCLUSIONS: Our results support the use of pre-treatment ALI, an easily measurable inflammatory/nutritional index, in daily clinical practice to improve prognostic stratification in surgically treated HPV-negative HNSCC.

The 15th century cross-vaults of the medieval Modena Cathedral (UNESCO site) consist of intricate patches of different masonry portions bound by three types of lime mortars and at least two types of gypsum mortars. Such anomalous structure suggests multiple repair works over time after damaging earthquakes. The absolute dating of lime mortars (14C) and bricks (TL) integrated with the pollen record of mortars allowed to clarify the construction and restoration history of the vaults and to link the repairs to the earthquake chronology for the area. The results reveal that the original construction of the vaults (1404–1454) was carried out using lime mortar binding reused Roman and medieval older bricks. Lime mortar was used also for later repairs caused by earthquakes in the 16th and 17th centuries. Gypsum mortars were then used to entirely rebuild some vaults and to repair others in the 18th and 19th centuries. The study indicates that unexpected damage could be revealed by the detailed chronology of masonry binders. These data represent fundamental steps to implement earthquake risk assessments and strengthening projects of ancient buildings.

Objectives Nodal metastasis is an important prognosticator in primary parotid cancers. The management of the clinically node-negative neck is an area lacking consensus. This study investigates the occult nodal metastasis rate, and prognostic indicators in primary parotid cancers. Materials and methods We performed a multicentre retrospective case note review of patients diagnosed and treated surgically with curative intent between 1997 and 2020. Demographic, clinic-pathological and follow-up data was recorded. Results After exclusions, 334 patients were included for analysis, with a median follow-up of 48 months. The overall rate of occult lymph node metastasis amongst patients undergoing elective neck dissection was 22.4%, with older age, high-grade and more advanced primary tumours being associated with higher rates. On multivariable analysis, age ≥ 60 years (HR = 2.69, p = 0.004), high-grade tumours (HR = 2.70, p = 0.005) and advanced primary tumours (pT3-4, HR = 2.06, p = 0.038) were associated with worse overall survival. Occult nodal metastasis on final pathology was associated with a close-to-significant reduction in regional recurrence free survival (HR = 3.18, p = 0.076). Conclusion This large series confirms the significant occult lymph node metastasis rate in primary parotid cancer, and demonstrates the importance of primary histology, tumour grade and stage in predicting survival outcome. This data supports the use of elective neck dissection in patients with high-risk tumours.

To investigate the prognostic significance of the stratification of extranodal extension (ENE) into ENE minor (ENEmi, up to 2 mm) and ENE major (ENEma, over 2 mm) in non-HPV-related squamous cell cancers of the head and neck, we retrospectively reviewed microscopic slides from neck dissection specimens of ENE-positive patients and subcategorised them into ENEmi and ENEma. We then compared the two groups in terms of overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS). Forty-four patients with pathologically positive necks had ENE in the histological report. Twenty-six had ENEmi and 18 ENEma. The three-year OS was 46% in the ENEmi group and 38.9% in the ENEma group. DSS and DFS were 80.8% and 80.8%, respectively, in the ENEmi group and 61.1% and 77.8%, respectively, in the ENEma group. None of the comparisons revealed any statistically significant difference. The results of our survival analysis seem to show a trend towards better survival rates in the ENEmi group, particularly regarding OS. Nonetheless, extension of the tumour outside the lymph node capsule by more than 2 mm was not found to be significantly associated with any of the explored survival outcomes.

Background Emerging reports suggest that new onset of smell or taste loss are potential early clinical markers of SARS-CoV-2 infection, but it remains unclear as to what extent. Therefore, the purpose of this study is to systematically assess the prevalence of self-reported altered sense of smell or taste in patients with confirmed SARS-CoV-2 infection, overcoming the limitations of individual studies by meta-analysis of pooled data. Methods The databases Medline, Embase, Web of Science, Scopus and MedRxiv's set were searched from inception to the 4th May 2020. This study was conducted following the PRISMA checklist. Results 18 studies met the eligibility criteria out of the 171 initially screened citations. The overall prevalence of alteration of the sense of smell or taste was 47% , but estimates were 31% and 67% in severe and mild-to-moderate symptomatic patients, respec- tively. The loss of smell and taste preceded other symptoms in 20% of cases and it was concomitant in 28%. Conclusions Based on this meta-analysis, we recommend self-isolation and testing, where possible, for patients complaining smell or taste impairment during COVID-19 pandemic in order to prevent spread of disease and propose the inclusion of loss of smell and taste as recognized symptoms of SARS-CoV-2 in the World Health Organization and other relevant regulatory body's lists.

Objectives: In the past literature agreed on treating oral carcinomas, using an “en-bloc” resection (EBR) but recently minimally invasive transoral surgery has spread as the preferable treatment for selected cases. This latter technique, which is performed with a discontinuous resection (DR), allows for a satisfactory postoperative quality of life (QoL) maintaining good survival rates. Materials and methods: In this study, we analyzed data about 147 surgically treated patients with oral cancer involving tongue and floor of the mouth. The sample was divided according to the surgical approach: EBR and DR group which were compared in terms of recurrence, overall survival, disease-free survival, and QoL. Results: In the DR group, survival analysis showed better results in term of survival, locoregional control, and postoperative anxiety, while the other QoL scores were similar in the two groups. Conclusion: The more invasive approach does not correlate to a better outcome. In selected cases, DR is an oncologically safe technique; EBR is still a valid option to treat advanced oral cancers.

Background Nasopharyngoscope reprocessing methods should be effective, rapid and reproducible with moderate cost. Tristel Trio Wipes system (TTWS) is a manual reprocessing method based on chlorine dioxide that has lately emerged in ENT department. This review aims to collect evidence on this system. Methods The PubMed, Web of Science and Cochrane Library databases were searched for all the studies on TTWS or one of its components. Data were grouped according to the study type. Results Ten articles were included in the review. TTWS ensured high-level disinfection in laboratory and clinical setting. Although the limitations of the manual systems, TTWS proved to be faster than automated endoscope reprocessing (AER) and safe for patients and health-care workers. TTWS represented cheaper system than AER or sheaths in low- and medium-volume centers. Conclusion TTWS could be a valid, safe and fast HLD method for nasopharyngoscopes, with reasonable costs for medium-low reprocessing volumes.

The 8th edition of the American Joint Committee on Cancer (AJCC) Staging Manual introduces "depth of invasion" and "extranodal extension" into the head and neck section, and our aim was to find out if these changes have an impact on prognosis. We evaluated 174 patients who had had oral squamous cell carcinomas (SCC) resected between 2003 and 2012. The clinical records were reviewed, the patients' tumours restaged according to the 8th edition of the AJCC, and we analysed five-year survival to verify whether different correlations were made between the T and N stages and disease-specific survival using the 7th and 8th editions. We excluded seven cases because information was incomplete, and the final sample was 167 patients. The five-year overall survival was 68% and the five-year disease-specific survival was 78%. The variable pT was upstaged in 51 patients (31%), and no tumour was downstaged. When we used the 7th edition, the pT category did not correlate with survival (p=0.055), but when we used the 8th edition, there was a significant association between increased pT categories and disease-specific survival (p=0.01). In the pN category 23 cases were upstaged (14%) and this affected disease-specific survival using both the 7th and the 8th editions (p=0.001). When patients were restaged, there was an improvement in discrimination between T categories in relation to disease-specific survival, and confirmation of the prognostic impact of the variable pN. T stage and depth of invasion are complementary predictors of disease-specific survival, and their combination results in the new AJCC staging system giving a better prognosis.

surgical resection of oral cancer can be by en-bloc or discontinuous approach.

Malignant external otitis (MOE) is a severe infection of the external auditory canal and the skull base that is often seen in elderly diabetic patients with a high mortality and morbidity rate. in >98% of cases, the causative pathogen is Pseudomonas aeruginosa. Here, we describe a case of MOE associated with facial nerve paralysis in a patient hospitalized. A 62-year-old man was referred to our department experiencing right otalgia, purulent otorrhea, ear loss, and a Grade III right facial nerve palsy according to the House–Brackmann scale. He was affected by uncompensated insulin-dependent type 2 diabetes. The patient had a history of noncholesteatomatous ipsilateral chronic otitis treated with tympanomastoid surgery 10 years before, without any sign of recurrence. After 10 days of specific antibiotic and corticosteroid therapy, symptoms were reduced and the paralysis of the superior branches of the facial nerve had improved, but the persisting swell of the ear canal did not allow a thorough evaluation of the tympanic membrane. Therefore, an explorative tympanotomy was performed, and few days after surgery, the marginalis branch paralysis of the facial nerve had improved according toelectroneurography (ENG) results, and the culture swab showed a polymicrobial flora.

Riassunto Obiettivi Il rabdomiosarcoma e un tumore maligno dei tessuti molli che origina dal muscolo scheletrico; e stato inizialmente descritto nel 1854 e rappresenta piu del 50% dei sarcomi dei tessuti molli nei giovani pazienti. Diagnosticare un rabdomiosarcoma e spesso difficile dato che, clinicamente, non ha caratteristiche patognomoniche e univoche. Materiali e metodi Si riporta il caso di un rabdomiosarcoma facilmente confondibile con una lesione di origine odontogena, diagnosticato a un giovane di 24 anni. Per giungere alla diagnosi finale sono state necessarie piu fasi e tecniche quali l’istopatologia, l’immunoistochimica e l’imaging, in aggiunta all’aspetto clinico. Risultati e conclusioni La diagnosi precoce delle lesioni maligne del cavo orale riveste un ruolo determinante per la prognosi. E necessario adottare un atteggiamento critico e consapevole per non incorrere in errori diagnostici e, conseguentemente, terapeutici. Inoltre e opportuno che i casi sospetti o dubbi siano tempestivamente inviati a strutture specializzate di riferimento per ottimizzare la gestione del piano diagnostico-terapeutico.

Context: Antipituitary antibodies (APA) recognizing GH-secreting cells may indicate an autoimmune pituitary involvement in adults with idiopathic GH deficiency (IGHD). Objective: We aimed 1) to investigate the presence of APA in prepubertal children with IGHD or idiopathic short stature (ISS), identifying the pituitary hormone-producing cells targeted by APA; and 2) to verify whether in patients with ISS the presence of APA could predict the development of GHD. Design: We performed a cross-sectional and partially longitudinal cohort study. Setting: The study was performed at the Endocrinology Unit and Pediatric Unit of the Second University and University Federico II of Naples, respectively. Patients: Twenty-six children with IGHD (group 1), 60 children with ISS (group 2), 33 children with GHD caused by lesions/abnormalities of the hypothalamus or pituitary (group 3), and 40 controls participated in the study. Nineteen children of group 2 were reevaluated after 2 yr. Main Outcome Measures: IGF-I levels, GH secretion, and APA (by indirect immunofluorescence) were evaluated in all participants. Results: At study entry, APA recognizing GH-producing cells were detected in seven of 26 children in group 1 and in 14 of 60 in group 2. Two years later, all eight initially APA-positive and all 11 APA-negative of the 19 reevaluated patients persisted positive and negative, respectively. The reevaluation of GH secretion in these patients revealed the development of GHD in all but one of the APA-positive children but in none of the APA-negative ones. Conclusions: IGHD in children can be frequently associated with APA targeting GH-secreting cells; thus, the detection of APA in children with ISS could identify those prone to develop GHD.

ObjectiveWhile anti-pituitary antibodies (APAs) were detected in some patients with Sheehan's syndrome (SS) suggesting an autoimmune pituitary involvement in the development of their hypopituitarism, hypothalamic cell anti-hypothalamus antibodies (AHAs) have not been investigated so far.DesignThe aim of this study was to evaluate the presence of AHA and APA in SS patients to verify whether an autoimmune hypothalamic–pituitary process can contribute to their late hypopituitarism.MethodsTwenty women with SS with a duration of disease ranging from 3 to 40 years (median 25.5 years) were enrolled into the study. Out of 20 patients, 12 (60%) had panhypopituitarism and the others had partial hypopituitarism well corrected with appropriate replacement therapy. None of them had clinical central diabetes insipidus. AHA and APA were investigated by immunofluorescence method in all patients. In addition, a four-layer immunofluorescence method was used to verify whether AHA immunostained vasopressin-secreting cells (AVP-c) or not.ResultsAHAs were found in 8 out of 20 (40%) and APAs in 7 out of 20 (35%) patients with titers ranging from 1:32 to 1:128 and 1:16 to 1:32 respectively; however, in none of these positive patients AHA immunostained vasopressin cells. None of controls resulted positive for both antibodies.ConclusionsPatients with SS, even many years after the onset of SS, can show antibodies to pituitary and/or hypothalamic but not AVP-secreting cells. Antibodies to unknown hypothalamic cells (releasing factor-secreting cells) other than APAs suggest that an autoimmune process involving both the hypothalamus and pituitary gland may contribute to late pituitary dysfunction in SS patients.

LYH (lymphocytic hypophysitis) is an autoimmune disease of the pituitary gland which can present with varying degrees of pituitary hormonal impairment and/or with symptoms related to pituitary enlargement. In this review, we provide an overview of the epidemiology, diagnosis, pathogenesis, treatment, and the role of organ-specific and antipituitary antibodies as potential markers of LYH. In addition, although the mechanisms underlying LYH are not completely understood, the role of prolactin, which plays an important part in maintaining immune system homoeostasis and is increased in the disease, is considered.

Summary objective The aim of this study was twofold: first to investigate the presence of extraocular muscle antibodies (EMAb) in sera of Graves’ patients with ophthalmopathy characterized by clinical extraocular muscle (EM) involvement; second to evaluate in Graves’ patients without ophthalmopathy whether longitudinal variations of EMAb have a predictive role for the development of eye disease. patients We evaluated sera of Graves’ patients previously tested for G2sAb and FpAb; in particular, sera of 32 patients with moderate or severe ophthalmopathy and EM involvement: 18 with active disease (group 1), 14 with inactive disease (group 2). Moreover, we evaluated longitudinally sera of 19 Graves’ patients without ophthalmopathy previously tested for anti-GS2 (G2sAb) and antiflavoprotein antibodies (FpAb; group 3). During the 18-month follow-up, four of them did not develop ophthalmopathy (group 3a), and 15 did: seven developed eye disease (group 3b) with clinical EM involvement. In particular, moderate disease and clinical activity score (CAS) ≥ 4 in four of them, severe ophthalmopathy and CAS ≤ 1 in three were observed. The remaining eight patients showed moderate ophthalmopathy and CAS ≥ 4 without EM involvement (group 3c). measurements EMAb were evaluated in all samples by indirect immunofluorescence method. results EMAb were detected in 13 out of 18 patients (72·2%) in group 1 (titre 1/32–1/128) and in five out of 14 patients (35·7%) in group 2 (titre 1/2–1/8). As regards to group 3, at the start of the study EMAb were detected in 13 out of 19 patients (72%) at titres 1/2–1/8; during the follow-up they became or persisted negative in all patients in group 3a, while they increased at titres ranging from 1/64 to 1/128 in all patients in group 3b before the onset of ophthalmopathy. Finally, in group 3c, four patients showed a mild increase (1/8–1/16) of EMAb before the onset of eye disease, while four patients were negative during the entire follow-up. conclusions Our results indicate that EMAb are a good marker of ophthalmopathy with EM involvement and their titre is higher in patients with active than in those with inactive disease. Thus, even if our results must be confirmed on a larger cohort of patients, the increase of EMAb in patients with Graves’ disease could be considered as a risk factor for the development of ophthalmopathy with subclinical/clinical EM impairment. In this connection we propose the evaluation of EMAb, in Graves’ patients with subclinical and clinical ophthalmopathy, as a simple and sensitive marker of the EM inflammatory process.

A possible autoimmune aggression to pituitary somatotrophs has been suggested by the occurrence of antipituitary antibodies (APA) directed against GH-secreting cells in some cases of GH deficiency (GHD) both in adults and in children and in some patients with autoimmune poliendocrine syndrome. We also detected APA in some patients with idiopathic short stature (ISS) and suggested that the presence of these antibodies could identify those of them prone to develop GHD. In fact, patients with ISS, resulted positive for APA at the first observation, during a longitudinal follow-up showed an impaired GH response to the stimuli in subsequent years suggestive of acquired GHD. Also in such patients we demonstrated that the target of APA were the somatotrophs and that an autoimmune attack to these cells may be the underlying cause of hormonal impairment in several children with GHD positive for APA. In this connection we suggested that in these patients an early iso-hormonal therapy with recombinant GH may be useful to interrupt or delay the progression towards a clinical GHD.
