RESUMO
OBJECTIVE: Restriction in healthcare services during the COVID-19 pandemic caused delays in the diagnosis and treatment of several diseases. To overcome the risk of missed diagnosis of head and neck cancers, before deleting the scheduled appointments, we have introduced a selection of the patients by examining the clinical presenting issue and previous medical history. The aim of this study is to show the effects of the abovementioned strategy on the diagnosis and management of laryngeal cancer. METHODS: Data were extracted from the Hospital software regarding the new diagnosis of laryngeal SCC in the periods from March 2020 to December 2020 during the pandemic (study group) and from March 2019 to December 2019 (control group) were collected. Data were compared regarding: TNM stage, time from first medical examination to histological diagnosis (Time-1), and time form histological diagnosis to beginning of treatments (Time-2). RESULTS: The final study group was composed by 19 laryngeal cancers, the control group by 25 cases. No significant differences were found in the tumour stage between the groups. In the study group, Time-1 was shorter (24 days versus 43 days, p = 0.012), while Time-2 in surgically-treated patients was longer (20 days versus 9 days, p = 0.012). CONCLUSION: During the pandemic, there was a dramatic lack of medical and nurse staff needed for surgical procedures. As consequence, the time between the diagnosis of malignancy and surgical treatment increased. In our unit, an efficient patient selection strategy to reschedule medical appointments avoided a dangerous shift toward higher laryngeal cancer stages.

PURPOSE: The aim of this study is to provide a systematic review of the literature about the etiology, clinical and radiological presentation, surgical management, and outcomes of pneumolabyrinth (PNL). METHODS: A systematic review of the literature was performed including studies published up to September 2020 in electronic databases (PubMed/MEDLINE, EMBASE, Cochrane Library, and Scopus). The PRISMA standard was applied to identify English, Italian, or French-language studies mentioning PNL. Full texts lacking information on the etiology were excluded. Data concerning the cause, site of air bubbles/fistula, clinical presentation, treatment, and outcome were collected. A qualitative synthesis of the results was performed. RESULTS: Seventy-eight articles were eventually included; 132 patients were involved in the qualitative synthesis. The most common causes were: stapes surgery (24/132, 18.2%), temporal bone fracture (42/132, 31.8%), head trauma without temporal bone fracture (19/132, 14.4%), penetrating trauma (21/132, 15.9%), and barotrauma (15/132, 11.4%). The site most commonly involved was the vestibule (102/107, 95.3%), followed by cochlea (43/107, 40.2%) and semicircular canals (25/107, 23.4%). CONCLUSION: The etiopathogenesis of PNL can be summarized in traumatic, iatrogenic, or inflammatory/infective. Its management consists in exploratory tympanotomy and sealing the fistula, but also conservative treatments can be attempted. Vestibular symptoms disappear in the majority of cases. Instead, the prognosis of hearing function is widely variable, and complete recovery is less probable. The certainty of evidence is still too low to make it useful for clinical decision-making.

PURPOSE: To correlate objective measures of audio-vestibular function with superior canal dehiscence (SCD) size and location in ears with SCD and compare results with literature. METHODS: We retrospectively evaluated 242 patients exhibiting SCD and/or extremely thinned bone overlying superior canals (SC) on CT scans and selected 73 SCD patients (95 ears with SCD). Data concerning audiometry, impedance audiometry, video-head impulse test (vHIT), cervical vestibular-evoked myogenic potentials (cVEMPs) and ocular VEMPs (oVEMPs) to air- (AC) and bone-conducted (BC) stimuli were collected for each pathologic ear and correlated with dehiscence size and location. RESULTS: AC pure-tone average (PTA) (p = 0.013), low-frequency air-bone gap (ABG) (p < 0.001), AC cVEMPs amplitude (p = 0.002), BC cVEMPs amplitude (p < 0.001) and both AC and BC oVEMPs amplitude (p < 0.001) positively correlated with increasing SCD size. An inverse relationship between dehiscence length and both AC cVEMPs and oVEMPs thresholds (p < 0.001) and SC vestibulo-ocular reflex (VOR) gain (p < 0.001) was observed. Dehiscences at the arcuate eminence (AE) exhibited lower SC VOR gains compared to SCD along the ampullary arm (p = 0.008) and less impaired BC thresholds than dehiscences at the superior petrosal sinus (p = 0.04). CONCLUSION: We confirmed that SCD size affects AC PTA, ABG and both amplitudes and thresholds of cVEMPs and oVEMPs. We also described a tendency for SC function to impair with increasing SCD size and when dehiscence is located at the AE. The latter data may be explained either by a spontaneous canal plugging exerted by middle fossa dura or by a dissipation through the dehiscence of mechanical energy conveyed to the endolymph during high-frequency impulses.

Objective: The aim of this study was to report the rationale and selection criteria for hemithyroidectomy and ipsilateral central neck dissection in patients with selected papillary thyroid cancer and to report the surgical and oncological outcomes. Design: Single-institution retrospective observational study. Methods: The clinical records of patients with a histopathological diagnosis of low-risk pT1 papillary thyroid cancer who underwent hemithyroidectomy with or without ipsilateral central neck dissection between March 2000 and April 2018 at a tertiary referral center were retrospectively reviewed. Demographic, clinical, and histopathological data were collected. Results: During the study period, 176 patients underwent hemithyroidectomy for PTC. Thirteen patients (13/176, 7.39%) were lost to follow-up and 74 patients (74/163 45.40%) underwent completion thyroidectomy within 1 month because they were classified intermediate ATA initial risk based on definitive pathology. The final study group was composed of 89 patients, who had a median follow-up of 5.3 years. The mean follow-up was 6.3 years (range: 36-207 months). Eighty-four patients (94.38%) did not experience recurrence in the follow-up period. A total of 5/89 patients (5.62%) underwent delayed completion thyroidectomy with or without neck dissection for recurrent malignancy in the residual lobe (3/5) or regional lymph nodes (2/5). The median time from surgery to recurrence was 24.8 months (range: 6-60). The follicular variant was an independent risk factor for recurrence. Conclusions: Hemithyroidectomy with or without prophylactic ipsilateral central neck dissection is a valuable treatment option in selected low-risk papillary thyroid cancers and ensures a low risk of recurrence. Prophylactic ipsilateral central compartment dissection could have a role in improving cancer staging, and accurate ultrasonographic follow-up is essential to identify local recurrence.

NUT carcinoma (NUT-C) is a relatively new malignancy that was recently listed in the 4th edition of the WHO Classification of Head and Neck Tumors in 2017. NUT carcinoma is a rare, aggressive, poorly differentiated carcinoma genetically defined by chromosomal rearrangement of the nuclear protein in testis (NUTM1) gene. The prognosis is extremely poor, with a mean survival < 1 year. Recent publications suggest a multimodality treatment approach. In the existing literature, only a few reports of sinonasal NUT-C have been reported. Sinonasal NUT-C is considered a very rare entity, but because of its recent inclusion as a head and neck malignancy, its true prevalence is unknown. We report the case of a 56-year-old woman with NUT-C of the sinonasal cavities. In the case reported, the coexistence of Coronavirus disease 2019 (COVID-19)-related nasal congestion delayed the diagnosis of NUT-C. Clinical presentation, diagnosis and treatment modalities are discussed together with a review of the literature.

We describe a case series of labyrinthine fistula, characterized by Hennebert's sign (HS) elicited by tragal compression despite global hypofunction of semicircular canals (SCs) on a video-head impulse test (vHIT), and review the relevant literature. All three patients presented with different amounts of cochleo-vestibular loss, consistent with labyrinthitis likely induced by labyrinthine fistula due to different temporal bone pathologies (squamous cell carcinoma involving the external auditory canal in one case and middle ear cholesteatoma in two cases). Despite global hypofunction on vHIT proving impaired function for each SC for high accelerations, all patients developed pressure-induced nystagmus, presumably through spared and/or recovered activity for low-velocity canal afferents. In particular, two patients with isolated horizontal SC fistula developed HS with ipsilesional horizontal nystagmus due to resulting excitatory ampullopetal endolymphatic flows within horizontal canals. Conversely, the last patient with bony erosion involving all SCs developed mainly torsional nystagmus directed contralaterally due to additional inhibitory ampullopetal flows within vertical canals. Moreover, despite impaired measurements on vHIT, we found simultaneous direction-changing positional nystagmus likely due to a buoyancy mechanism within the affected horizontal canal in a case and benign paroxysmal positional vertigo involving the dehiscent posterior canal in another case. Based on our findings, we might suggest a functional dissociation between high (impaired) and low (spared/recovered) accelerations for SCs. Therefore, it could be hypothesized that HS in labyrinthine fistula might be due to the activation of regular ampullary fibers encoding low-velocity inputs, as pressure-induced nystagmus is perfectly aligned with the planes of dehiscent SCs in accordance with Ewald's laws, despite global vestibular impairment on vHIT. Moreover, we showed how pressure-induced nystagmus could present in a rare case of labyrinthine fistulas involving all canals simultaneously. Nevertheless, definite conclusions on the genesis of pressure-induced nystagmus in our patients are prevented due to the lack of objective measurements of both low-acceleration canal responses and otolith function.
RESUMO
OBJECTIVES: Luc's abscess is a rare complication of acute otitis media, with a challenging diagnosis and a controversial surgical treatment. The aim of the present study was to review the published literature in order to clarify the clinical features and the surgical management of those patients. METHODS: A systematic review of the literature was carried out for published reports or case series in English language, describing a temporo-zygomatic (or Luc's) abscess which complicated an acute or chronic otitis media and/or mastoiditis, confirmed through CT scan or MRI of the petrous bone. The collected clinical and radiological data were merged and critically appraised. RESULTS: Eighteen reports of Luc's abscess were included. Adding our case report, a total of 21 cases were included in the analysis. Abscess drainage plus myringotomy alone vs. abscess drainage plus myringotomy and mastoidectomy were the two surgical management approaches described in the literature. Patients undergoing first line mastoidectomy were successfully treated in all cases, while among those undergoing a more conservative approach, one failure required subsequent mastoidectomy. CONCLUSIONS: The clinical features of Luc's abscess are rather constant and help in rising the suspicion before the radiological diagnosis. Although cases with associated intra-cranic complications have been reported, the limited existing data do not permit to advocate the mastoidectomy over a more conservative surgical approach. However, the decision to avoid mastoidectomy as the first line surgical treatment should be based on the clinical and radiologic assessment, after an accurate counseling, particularly in the case of a pediatric patient.

We describe a rare case of posterior semicircular canal (PSC) fibrosis following acute labyrinthine ischemia in the territory supplied by the common cochlear artery (CCA) and review the relevant literature. A 71-year-old man with multiple vascular risk factors presented 12 days after the onset of acute vertigo and profound left-sided hearing loss. Right-beating spontaneous nystagmus with downbeat components elicited by mastoid vibrations and headshaking was detected. The video head impulse test (vHIT) revealed an isolated hypofunction of the left PSC, whereas vestibular evoked myogenic potentials (VEMPs) showed ipsilateral saccular loss. The clinical presentation and instrumental picture were consistent with acute ischemia in the territory supplied by left CCA. Compared to previous imaging, a new MRI of the brain with 3D-FIESTA sequences highlighted a filling defect in the left PSC, consistent with fibrosis. Hearing function exhibited mild improvement after steroid therapy and hyperbaric oxygen sessions, whereas vHIT abnormalities persisted over time. To the best of our knowledge, this is the only case in the literature reporting a filling defect on MRI, consistent with semicircular canal fibrosis following acute labyrinthine ischemia. Moreover, PSC fibrosis was related with poor functional outcome. We therefore suggest using balanced steady-state gradient-echo sequences a few weeks following an acute lesion of inner ear sensors to detect signal loss within membranous labyrinth consistent with post-ischemic fibrosis. Besides addressing the underlying etiology, signal loss might also offer clues on the functional behavior of the involved sensor over time. In cases of acute loss of inner ear function, a careful bedside examination supplemented by instrumental assessments, including vHIT and VEMPs, of vestibular receptors and afferents may be completed by MRI with balanced steady-state gradient-echo sequences at a later time to confirm the diagnosis and address both etiology and functional outcome.
RESUMO
Objective The aims of the present study were to evaluate the clinical significance of the delay for surgical treatment and the prognostic value of other clinical, pathologic, and microbiological variables among hematologic patients affected by acute invasive fungal rhinosinusitis (AIFRS). Furthermore, we propose our early diagnosis and treatment protocol, reporting its 10-year results. Study Design Monocentric retrospective analysis. Setting The study was conducted from 2001 to 2017 at the University Hospital of Bologna, Italy. Subjects and Methods The impact of time to treatment and clinical, pathologic, and microbiological variables were analyzed among patients with histologically and microbiologically proven AIFRS. The outcomes of patients treated before the introduction of the early diagnosis protocol were compared with those treated afterward. Results Nineteen patients affected by AIFRS were eligible for the study. Treatment delay >4 days ( P = .002), infection caused by Mucorales ( P = .015), and extension of the disease were negative prognostic variables ( P = .017). The application of our protocol significantly reduced the delay for diagnosis and appropriate treatment by an average of 7.3 days ( P = .02). Conclusion The promptness of the diagnosis and surgical treatment may play a significant role in the management of AIFRS, as it appears to be significantly associated with the disease outcome. Our protocol may help to reduce the time required for diagnosis of high-risk hematologic patients.
