Refractory Pseudomonas Osteomyelitis of the Skull Base With Gradenigo's Syndrome: Early Dysphagia and Late Abducens Nerve Palsy. J Med Cases 2024; 15:43-48. [PMID: 38646423 PMCID: PMC11027766 DOI: 10.14740/jmc4191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 03/05/2024] [Indexed: 04/23/2024] Open
Abstract
Gradenigo's syndrome (GS) is a rare entity characterized by otitis media, pain in the trigeminal nerve distribution and abducens nerve palsy. The classic triad is uncommon, making the diagnostic workup challenging. Specifically, the diagnostic approach includes medical history, a complete otorhinolaryngological examination, a pure-tone audiogram and radiological investigation such as contrast-enhanced computed tomography scan and magnetic resonance imaging of head and neck. Broad-spectrum antibiotics are the first-line treatment, such as intravenous (IV) ceftriaxone and IV metronidazole. Here, we present the case of a 71-year-old man with a previous history of otitis media and poorly controlled type 2 diabetes mellitus. He presented to our attention with facial pain, left hemilarynx paralysis, dysphagia and otorrhea. The patient was treated with broad-spectrum antibiotics without any clinical improvement. Imaging evaluations demonstrated the presence of wide and poorly defined pathological material with epicenter in the masticatory space, involving all nearby structures. The patient underwent multiple biopsies without obtaining a definitive tissue diagnosis of neoplasia. After 2 months, the patient developed delayed VI cranial nerve palsy, providing evidence of GS. Although incomplete, GS has been described in the literature; however, none of the cases exhibited a latent abducent deficit. To the best of our knowledge, this is the only case with a delayed onset of abducens nerve palsy.

Safety and efficacy of remifentanil target-controlled infusion for conscious sedation in a pregnant woman: a case report. J Med Case Rep 2024; 18:143. [PMID: 38454441 PMCID: PMC10921671 DOI: 10.1186/s13256-023-04303-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 12/05/2023] [Indexed: 03/09/2024] Open
Abstract
BACKGROUND Every year 2% of pregnant women undergo nonobstetric surgical interventions worldwide. According to the American College of Obstetricians and Gynecologists Committee on Obstetric Practice, pregnant women should never be denied the most appropriate surgical treatment, regardless of the trimester of pregnancy. However, additional attention should be paid during the first trimester since it has the highest risk of inducing teratogenic mutations; additionally, during the third trimester, due to the possibility of preterm birth and low birth weight of the newborn, great care should be paid. CASE PRESENTATION We present the case of a Caucasian 36-year-old woman during her 21st week of pregnancy, with a normal-sized fetus, according to the gestational age on ultrasound exam, and with no additional risk factors. The patient referred to an increasing nasal obstruction associated with rhinorrhea of the left nasal cavity. She also reported episodes of sleep apnea and hyposmia. The patient received a detailed otolaryngological examination, which allowed for identification of a mass within the left nasal cavity. The subsequent nasal endoscopy confirmed a grayish polypoid mass lesion with a multinodular surface occupying the entire left nasal fossa. The lesion totally obliterated the left maxillary sinus, resulting in obstruction of the anterior osteomeatal unit and ethmoidal sinusitis. She was referred for a functional endoscopic sinus surgery using analgosedation with remifentanil target-controlled infusion. DISCUSSION AND CONCLUSION To the very best of our knowledge, this is the first case described in English literature about the use of analgosedation with remifentanil target-controlled infusion for otolaryngology surgery, specifically in functional endoscopic sinus surgery. It could be an interesting option to avoid the use of inhaled anesthetics that could induce fetal damage, especially during the first months of pregnancy. Furthermore, patient intubation is not necessary, which avoids cases of difficult intubation or any trauma to the airways. An adequate informed consent and appropriate compliance are elements of paramount importance in tailoring the anesthetic strategy for pregnant women who need nonobstetric surgical management.

Multidisciplinary Decision-Making-ITAlian Consensus After Two Years of Real Practice on the Management of Severe Uncontrolled CRSwNP by Biologics (ITACA Study). Curr Allergy Asthma Rep 2024; 24:143-154. [PMID: 38472601 DOI: 10.1007/s11882-024-01135-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/31/2024] [Indexed: 03/14/2024]
Abstract
PURPOSE OF REVIEW We aimed to reach an Italian multidisciplinary consensus on some crucial aspects of treatment decision making in CRSwNP, following 2 years of clinical experience in order to support specialists in the management of CRSwNP in clinical practice. We addressed issues relating to therapeutic decision-making and shared criteria for the treatment choice, as well as appropriate timing and criteria for evaluating treatment response, and highlighted the need for repeated multidisciplinary assessments. RECENT FINDINGS A national survey has been conducted recently to understand how rhinology practice has changed in Italy with the advent of biologics and how this affects patients with uncontrolled, severe CRSwNP. Despite the many published consensus documents, practical recommendations, and protocols on the use of biologics in CRSwNP, heterogenous behaviors in practice are still observed mainly conditioned by the novelty of the topic. The consensus procedure followed a modified Delphi approach. The scientific board included 18 otorhinolaryngologists and 8 allergists, who selected the 4 main topics to be addressed and developed overall 20 statements. Consensus on these statements was sought by a larger group of 48 additional experts, through two rounds of voting, the first web-based, the second in presence with discussion and possible refinement of the statements. The statements reaching an average score ≥ 7 at the second voting round were approved. Five statements were proposed for each of the following topics: baseline evaluation of patients eligible for biologic therapy; choice between different therapeutic options; assessment of the response to biologic treatment; multidisciplinary management. At the first voting round, 19 out of the 20 statements reached a mean score ≥ 7. Following the discussion and a few consequent amendments, at the second round of voting all the 20 statements were approved.

The Impact of Antibiotics and Steroids on the Nasal Microbiome in Patients with Chronic Rhinosinusitis: A Systematic Review According to PICO Criteria. J Pers Med 2023; 13:1583. [PMID: 38003898 PMCID: PMC10671981 DOI: 10.3390/jpm13111583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 11/03/2023] [Accepted: 11/05/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND The nasal microbiome represents the main environmental factor of the inflammatory process in chronic rhinosinusitis (CRS). Antibiotics and steroids constitute the mainstay of CRS therapies. However, their impact on microbial communities needs to be better understood. This systematic review summarizes the evidence about antibiotics' and steroids' impact on the nasal microbiota in patients with CRS. METHODS The search strategy was conducted in accordance with the PRISMA guidelines for systematic reviews. The authors searched all papers in the three major medical databases (PubMed, Scopus, and Cochrane Library) using the PICO tool (population, intervention, comparison, and outcomes). The search was carried out using a combination of the key terms "Microbiota" or "Microbiome" and "Chronic Rhinosinusitis". RESULTS Overall, 402 papers were identified, and after duplicate removal (127 papers), excluding papers off-topic (154) and for other structural reasons (110), papers were assessed for eligibility; finally, only 11 papers were included and summarized in the present systematic review. Some authors used only steroids, other researchers used only antibiotics, and others used both antibiotics and steroids. With regard to the use of steroids as exclusive medical treatment, topical mometasone and budesonide were investigated. With regard to the use of antibiotics as exclusive medical treatments, clarithromycin, doxycycline, roxithromycin, and amoxicillin clavulanate were investigated. Regarding the use of both antibiotics and steroids, two associations were investigated: systemic prednisone combined with amoxicillin clavulanate and topical budesonide combined with azithromycin. CONCLUSIONS The impact that therapies can have on the nasal microbiome of CRS patients is very varied. Further studies are needed to understand the role of the nasal microbiome, prevent CRS, and improve therapeutic tools for personalized medicine tailored to the individual patient.

Current role of artificial intelligence in head and neck cancer surgery: a systematic review of literature. EXPLORATION OF TARGETED ANTI-TUMOR THERAPY 2023; 4:933-940. [PMID: 37970203 PMCID: PMC10645467 DOI: 10.37349/etat.2023.00174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 07/19/2023] [Indexed: 11/17/2023] Open
Abstract
Aim Artificial intelligence (AI) is a new field of science in which computers will provide decisions-supporting tools to help doctors make difficult clinical choices. Recent AI applications in otolaryngology include head and neck oncology, rhinology, neurotology, and laryngology. The aim of this systematic review is to describe the potential uses of AI in head and neck oncology with a special focus on the surgical field. Methods The authors performed a systematic review, in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, in the main medical databases, including PubMed, Scopus, and Cochrane Library, considering all original studies published until February 2023 about the role of AI in head and neck cancer surgery. The search strategy included a combination of the following terms: "artificial intelligence" or "machine learning" and "head and neck cancer". Results Overall, 303 papers were identified and after duplicate removal (12 papers) and excluding papers not written in English (1 paper) and off-topic (4 papers), papers were assessed for eligibility; finally, only 12 papers were included. Three main fields of clinical interest were identified: the most widely investigated included the role of AI in surgical margins assessment (7 papers); the second most frequently evaluated topic was complications assessment (4 papers); finally, only one paper dealt with the indication of salvage laryngectomy after primary radiotherapy. Conclusions The authors report the first systematic review in the literature concerning the role of AI in head and neck cancer surgery. An increasing influx of AI applications to clinical problems in otolaryngology is expected, so specialists should be increasingly prepared to manage the constant changes. It will always remain critical for clinicians to use their skills and knowledge to critically evaluate the additional information provided by AI and make the final decisions on each patient.

Biologics in severe uncontrolled chronic rhinosinusitis with nasal polyps: A bicentric experience. ACTA BIO-MEDICA : ATENEI PARMENSIS 2023; 94:e2023227. [PMID: 37850768 PMCID: PMC10644941 DOI: 10.23750/abm.v94i5.14745] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Accepted: 06/27/2023] [Indexed: 10/19/2023]
Abstract
BACKGROUND AND AIM The introduction of biologics in the management of chronic rhinosinusitis with nasal polyposis (CRSwNP) has allowed new therapeutic options and Dupilumab represents the first approved biological agent. Aim of this paper is to provide a multicentric study in a real-life setting of treatment with Dupilumab for severe uncontrolled CRSwNP in Italy. METHODS A retrospective data collection was performed from the departments of Otolaryngology of two major health institutions in Rome: San Camillo Forlanini Hospital and Tor Vergata University. Both centres contributed to the study providing information about patients affected by severe uncontrolled CRSwNP and treated with Dupilumab. RESULTS A total of 83 patients were included in the study (43 males; 40 females; mean age: 55.8 years). Monitoring our patients, we observed improvement in reduction of nasal polyposis and nasal obstruction, respectively measured through NPS and PNIF. Concerning the CRSwNP symptoms and their impact on quality of life, we found an improvement in the olfaction, as measured respectively by SSIT-16 and SNOT-22. CONCLUSIONS Dupilumab has demonstrated broad efficacy in CRSwNP management. Further studies are needed to confirm our results and to establish biomarkers to identify endotypes and predict response to biologics treatment in CRSwNP.

Practical recommendations for managing severe chronic rhinosinusitis with nasal polyps in the era of biologics. ACTA OTORHINOLARYNGOLOGICA ITALICA : ORGANO UFFICIALE DELLA SOCIETA ITALIANA DI OTORINOLARINGOLOGIA E CHIRURGIA CERVICO-FACCIALE 2023; 43:324-340. [PMID: 37224173 PMCID: PMC10551726 DOI: 10.14639/0392-100x-n2422] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Accepted: 03/09/2023] [Indexed: 05/26/2023]
Abstract
Objective We conducted a national survey to understand how rhinology practice has changed with the advent of biologics and how this affected patients with uncontrolled, severe chronic rhinosinusitis with nasal polyps (CRSwNP). We aimed to analyse the results of the survey and infer practical recommendations for clinical practice. Methods A group of ear, nose, and throat specialists (ENTs) experienced in the management of CRSwNP developed a 74-question survey. ENTs from rhinology centres authorised to prescribe biologics in the context of the national health system were invited to answer it between 01/05/2022 and 31/07/2022. The responses underwent descriptive analyses, and the authors discussed the results and derived practical recommendations for clinical practice. Results ENTs working in rhinology centres changed their practices coinciding with the advent of biologics. CRSwNP evaluations have become more complex because they involve diagnostic confirmation, determining the patients' immunologic profile, and other factors. We observed heterogenous behaviours in practice that may be conditioned by the novelty of the topic. The results of the survey were used to develop practical recommendations for ENTs and are summarised herein. Conclusions Clinical practice in rhinology outpatient clinics has changed profoundly in the era of biologics. Our practical recommendations for clinicians working in rhinology centres are expected to help standardise practice and improve care.

Dupilumab's Impact on Blood Parameters in Nasal Polyposis: 18-Month Follow-Up in Real Life. J Immunol Res 2023; 2023:4027701. [PMID: 37745203 PMCID: PMC10516700 DOI: 10.1155/2023/4027701] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 07/30/2023] [Accepted: 08/25/2023] [Indexed: 09/26/2023] Open
Abstract
Background Dupilumab represents the first approved biological for severe uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP). Objective Aim of this paper is to provide a multicentric real-life study about treatment with dupilumab for CRSwNP with a special focus on blood parameters and IgE, IgG, and IgA. Method A retrospective data collection was jointly conducted at the Otolaryngology departments of San Camillo Forlanini Hospital and University of Rome "La Sapienza" from December 2020 to January 2023. Results A total of 130 patients were included in the study. Monitoring our patients for 18 months, we observed a reduction in nasal polyposis and an improvement in symptoms and their impact on quality of life. Regarding blood tests, a transient increase in blood eosinophils was found in most cases. Total IgE showed a gradual decrease in values. IgG and IgA also showed a slight reduction of values, while remaining within normal ranges. Conclusion To the best of our knowledge, this is the first study to evaluate the impact of dupilumab on several blood parameters in patients receiving treatment for CRswNP. Further studies are needed to confirm our results and to understand the underlying immunological mechanisms.

Uncertainties in the adaptation of alpine pastures to climate change based on remote sensing products and modelling. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2023; 336:117575. [PMID: 36893538 DOI: 10.1016/j.jenvman.2023.117575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 02/02/2023] [Accepted: 02/22/2023] [Indexed: 06/18/2023]
Abstract
Over the last century, the management of pastoral systems has undergone major changes to meet the livelihood needs of alpine communities. Faced with the changes induced by recent global warming, the ecological status of many pastoral systems has seriously deteriorated in the western alpine region. We assessed changes in pasture dynamics by integrating information from remote-sensing products and two process-based models, i.e. the grassland-specific, biogeochemical growth model PaSim and the generic crop-growth model DayCent. Meteorological observations and satellite-derived Normalised Difference Vegetation Index (NDVI) trajectories of three pasture macro-types (high, medium and low productivity classes) in two study areas - Parc National des Écrins (PNE) in France and Parco Nazionale Gran Paradiso (PNGP) in Italy - were used as a basis for the model calibration work. The performance of the models was satisfactory in reproducing pasture production dynamics (R2 = 0.52 to 0.83). Projected changes in alpine pastures due to climate-change impacts and adaptation strategies indicate that: i) the length of the growing season is expected to increase between 15 and 40 days, resulting in changes in the timing and amount of biomass production, ii) summer water stress could limit pasture productivity; iii) earlier onset of grazing could enhance pasture productivity; iv) higher livestock densities could increase the rate of biomass regrowth, but major uncertainties in modelling processes need to be considered; and v) the carbon sequestration potential of pastures could decrease under limited water availability and warming.

Diagnostic and Therapeutic Strategy for Vagal Schwannoma: Case Series and Literature Review. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1013. [PMID: 37374217 DOI: 10.3390/medicina59061013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 05/17/2023] [Accepted: 05/22/2023] [Indexed: 06/29/2023]
Abstract
Background and Objectives: Clinical management of vagal schwannoma is a real diagnostic and therapeutic challenge because the medical history and clinical examination are often non-specific and vagal nerve injury following surgical resection still represents an unsolved problem. The aim of this paper is to provide a case series along with a diagnostic and therapeutic algorithm for vagal schwannoma of the head and neck, combining our experience with clinical evidence available in the literature. Materials and Methods: We retrospectively analyzed a series of patients affected by vagal schwannoma who were treated between 2000 and 2020. In addition, a review of the literature on vagal schwannoma management was conducted. Based on the cases described and the literature review, we made a diagnostic and therapeutic algorithm for the management of vagal schwannoma. Results: We were able to identify 10 patients affected by vagal schwannoma and treated between 2000 and 2020. All patients presented with a painless, mobile, slow-growing lateral neck mass with onset varying from a few months to years. The preoperative diagnostic workup included ultrasound (US) in nine cases, computed tomography (CT) with contrast in six patients and magnetic resonance imaging (MRI) of the neck in seven cases. All patients included in this study were surgically treated. Conclusions: Vagal schwannoma management represents a true challenge for clinicians and surgery is currently the most effective therapeutic strategy. A multidisciplinary approach through the collaboration of otolaryngologist with other specialists is desirable to develop a tailored treatment plan for the patient.

Abstract
The authors performed a systematic review, in accordance with the PRISMA guidelines, across multiple databases, including all original studies published until November 2022, focusing on External auditory canal cholesteatoma (EACC) after radiation therapy (RT) for nasopharyngeal cancer (NC). Inclusion criteria were original articles reporting on secondary EACC after RT for NC. Articles were critically appraised to assess level of evidence using the Oxford Center for Evidence-Based Medicine criteria. Overall, 138 papers were identified and after duplicate removal (34 papers) and excluding papers not in English, 93 papers were assessed for eligibility; finally, only five papers were included and summarized with the three cases coming from our institution. These mainly involved the anterior and the inferior part of the EAC. The mean time of diagnosis after RT was the largest series of 6.5 years (with a range from 0.5 to 15.4 years). Patients undergoing RT for NC have 18 times a higher risk of developing EACC compared to the normal population. EACC is probably one of the most underreported side effects, because patients may present variable clinical findings, which could lead to misdiagnosis. Early diagnosis of RT related EACC is advised to enable conservative treatment.

Abstract
The aim of the present study was to obtain data from a large community sample of patients with Ménière's disease (MD) in Italy through a web-based nationwide survey. Demographic, clinical, and epidemiological features of MD among members of the Italian Association of Ménière's Disease (AMMI) were collected through a web-based survey. The questionnaire was posted on the AMMI website between 01/SEP/2021 and 31/OCT/2021. A total of 520 patients (374 F, 146 M) with MD were included. The age at interview (average ± standard deviation, SD) was 51.4 ± 10.9 years, with a disease duration of 9.9 ± 9.8 years. Eighty percent of cases were unilateral. No patients reported neurocognitive disorders or Parkinson's disease. A positive family history of MD was reported in 13% of participants, while a history of allergic diseases was reported in 33%. Comorbid thyroid disorders were present in 25% of participants, and 28% used betahistine as the main treatment. To our knowledge, this is the first study that has investigated the epidemiology and current patterns of care of MD in Italy, using an anonymous survey directly sent to patients, thus implying their active participation. We hope that future studies will support the utilization of web-based surveys to address the unmet needs in the management of patients with MD.

Abstract
INTRODUCTION Deep neck space infections (DNIs) represent serious bacterial infections affecting the deep cervical space and fascial planes of the neck. This study aims to describe our clinical and surgical experience in the management of DNIs, emphasizing the importance of appropriate imaging in the diagnostic setting and the role of the multidisciplinary approach according to the severity of the infection. METHODS In this retrospective study, we describe 85 patients affected by DNIs coming to the Otolaryngology department observation from the Emergency Room of San Camillo Forlanini Hospital in Rome from January 2006 to December 2021 and treated both by pharmacological and surgical therapy. RESULTS 54 patients (64%) were male, and 31 (36%) were female, with a mean age of 50.5 years. The most common cause of DNI was odontogenic, accounting for 70% of all collected cases. In 68 patients (80% of all cases), the surgical approach consisted of an extended unilateral cervicotomy, whereas in 17 patients (20% of all cases), a bilateral cervicotomy was performed. Surgical revision was required in 15 cases (18%). A tracheostomy was necessary in seven cases. The overall survival rate was 96.5%. CONCLUSIONS DNI represents a serious and life-threatening condition, remaining a constant challenge for the head and neck surgeon. Contrast-enhanced computed tomography is critical for therapeutic planning, which requires both a surgical approach and antibiotic therapy. Surgical treatment should be performed as soon as possible. In severe cases, the multidisciplinary approach is advisable.

A Practical Clinical Protocol for Monitoring Patients with Severe Uncontrolled Chronic Rhinosinusitis with Nasal Polyposis Treated with Biologics. ALLERGY & RHINOLOGY 2022; 13:21526567221074335. [PMID: 35127200 PMCID: PMC8808004 DOI: 10.1177/21526567221074335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
Objectives: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a pathological condition which leads to high healthcare-related costs and low quality of life for patients. The introduction of new biological therapies (monoclonal antibodies, MAbs) in CRSwNP patients has allowed new therapeutic options for non-responders to conventional therapies and Dupilumab represents the first approved biological agent. The aim of this paper is to provide a practical clinical multidisciplinary protocol which might help clinicians involved in this field to monitor the clinical outcomes. Methods: Our centre of Rhinology and Rhino-Allergology has developed a dedicated collection form to observe the outcomes of patients treated with Dupilumab. Our research started from the indications given in EPOS 2020 as main reference. We then implemented these references in an electronic database trying to apply Evidence Based Medicine (EBM) in current clinical practice. Results: The result consists of three parts: an anamnestic collection data, a clinician reported outcome and two patient reported outcomes (PROMs) questionnaire, the visual analogue scale (VAS) and the Sino-Nasal Outcome Test-22 (SNOT-22). The tables we propose should provide an adequate correlation with the patients’ adherence to therapy and their treatment outcomes. Such periodical evaluation (after a month, after 3 months, after 6 months and at one year) should quickly allow to monitor if the patient is correctly assuming the therapy and the eventual objective improvements. Conclusions: We propose a practical monitoring protocol formulated to analyse both objective and subjective aspects of patients with severe uncontrolled CRSwNP treated with MAbs, thus helping to define in future a better comparison between the clinical results of different institutes.

Biologics for severe uncontrolled chronic rhinosinusitis with nasal polyps: a change management approach. Consensus of the Joint Committee of Italian Society of Otorhinolaryngology on biologics in rhinology. ACTA ACUST UNITED AC 2021; 42:1-16. [PMID: 34297014 PMCID: PMC9058929 DOI: 10.14639/0392-100x-n1614] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 06/16/2021] [Indexed: 02/07/2023]
Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous inflammatory condition of nasal mucosa and paranasal sinuses, predominantly mediated by type 2 inflammation and often associated with comorbid asthma and/or Exacerbated Respiratory Disease (N-ERD). The standard of care involves local and systemic corticosteroids and/or sinonasal surgery, although these options may be associated with recurrences and patients may require revision surgery. Difficult-to-treat patients, in fact, have a more severe disease requiring high systemic corticosteroid use and/or multiple sinonasal surgeries. Literature data suggests that biologic agents targeting specific key effectors of type 2 inflammation may offer supplemental therapy for patients with severe and uncontrolled CRSwNP, leading to significant improvement in several outcomes. For these reasons, over the years the endotyping of the disease has become increasingly important. Herein, we provide not only an update on the existing studies about the most promising biologics in CRSwNP, but also critical discussion on controversies about the use of biologics in severe uncontrolled CRSwNP. We finally provide consensus on strategic issues gathered among experts of the Joint Committee of Italian Society of Otorhinolaryngology on biologics in order to offer the best care for difficult to treat patients.

Multimodal Simulation of a Novel Device for a Safe and Effective External Ventricular Drain Placement. Front Neurosci 2021; 15:690705. [PMID: 34194297 PMCID: PMC8236630 DOI: 10.3389/fnins.2021.690705] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Accepted: 05/04/2021] [Indexed: 11/13/2022] Open
Abstract
Background External ventricular drain (EVD) placement is mandatory for several pathologies. The misplacement rate of the EVD varies widely in literature, ranging from 12.3 to 60%. The purpose of this simulation study is to provide preliminary data about the possibility of increasing the safety of one of the most common life-saving procedures in neurosurgery by testing a new device for EVD placement. Methods We used a novel guide for positioning the ventricular catheter (patent RM2014A000376). The trajectory was assessed using 25 anonymized head CT scans. The data sets were used to conduct three-dimensional computer-based and combined navigation and augmented reality-based simulations using plaster models. The data set inclusion criteria were volumetric head CT scan, without midline shift, of patients older than 18. Evans' index was used to quantify the ventricle's size. We excluded patients with slit ventricles, midline shift, skull fractures, or complex skull malformations. The proximal end of the device was tested on the cadaver. Results The cadaveric tests proved that a surgeon could use the device without any external help. The multimodal simulation showed Kakarla grade 1 in all cases but one (grade 2) on both sides, after right and left EVD placement. The mean Evans' index was 0.28. The geometric principles that explain the device's efficacy can be summarized by studying the properties of circumference and chord. The contact occurs, for each section considered, at the extreme points of the chord. Its axis, perpendicular to the plane tangent to the spherical surface at the entry point, corresponds to the direction of entry of the catheter guided by the instrument. Conclusion According to our multimodal simulation on cadavers, 3D computer-based simulation, 3D plaster modeling, 3D neuronavigation, and augmented reality, the device promises to offer safer and effective EVD placement. Further validation in future clinical studies is recommended.

Abstract
There are many classifications for cholesteatomatous otitis media but none correspond exactly to the formulation of a surgical protocol for the middle ear and mastoid nor are any specific for the extension of the otitis media, making it difficult to interpret the published results. All the available classifications are limited to the cholesteatoma and, moreover, the variety of the reported studies in literature does not allow a standardization to define middle ear pathology and surgical procedures. The aim of this paper is to propose a novel staging system for middle ear diseases paying attention to the involvement of tympanic Cavity (C), Attic (A), and Mastoid (M): the CAM classification. In particular, CAM classification is composed of three symbols (0 / + / ρ) and two letters (t and m, tiny and ivory mastoid cases) related to the alphabetic initial of the macroscopic region, being able to allow a clear and specific description of the local situation. Moreover, the possibility to describe the temporal bone and the potential use of sub-groups to specifically define the involvement of the tympanic cavity and the attic could allow the creation of a common otologic language among all the different centres.

Abstract
Foreign bodies in pediatric age represent an extremely frequent pathological condition and can undergo fearsome complications. Within the ENT area, foreign bodies in the pediatric age can be found in various districts such as external auditory canal, nasal passages, oral cavity, pharynx, larynx and trachea. They can be various and shape; generally, the main ones are buttons, beads, small parts of toys, caps of pens, pebbles, fragments of food bolus and others. As described in the literature, the main localizations are the external auditory canal and nasal cavities. Laryngeal and tracheal localization is infrequent but can be fatal. The aspiration of foreign bodies, mainly small parts of toys, occurs more frequently under three years age and mainly-especially in males. The experience of the ENT Department of the San Camillo-Forlanini Hospital in Rome, in the period between January 2007 and December 2018, consists a total of 1443 patients, aged between 0 and 14, who arrived in the emergency room with a foreign body diagnosis; of these, 613 (42.5%) were found with foreign body in the external auditory canal, 458 (31.7%) in nasal fossa, 298 (20.5%) in pharynx, 64 (4.4%) in oropharynx, and 10 (0.7%) in larynx and trachea. Treatment was in 1255 (87%) removal in the emergency room and home discharge, 79 (5.4%) with outpatient discharge, 40 (2.7%) need for hospitalization and surgery, 64 (4.4 %) refusal of hospitalization and 1 case (0.07%) died in the emergency room.

Abstract
INTRODUCTION Ossifying fibromixoid tumor of soft parts (OFMT) is a rare soft tissue and bone tumor. In its classic form, is considered benign, nevertheless aggressive clinical behaviour tumors with a different cytoarchitectural features of a malignant variant, have been described.The classification contains "typical", "atypical" and "malignant" variants. METHODS A CT ear scan without contrast enhancement was carried out (October 2015), with coronal, sagittal and 3D reconstructions. It was decided the removal of the neoformation with a simple dissection. RESULTS In this report, we present a case of a typical variant OFMT localized in the retroauricular perimastoid region, with mastoid bone cortex not involved. CONCLUSIONS Considering the extreme rarity of this "enigmatic" tumor which displays an uncertain line of differentiation, renders the differential diagnosis a true challenge.

Abstract
BACKGROUND Universal newborn hearing screening (UNHS) aims to identify hearing loss in the early postnatal period; prompt detection of bilateral or unilateral hearing loss is mandatory for timely intervention. METHODS This retrospective study reports the results of the first two years of a UNHS program on 4,719 newborns in a large public Italian hospital. Screening was divided into two levels: automated transient otoacoustic emissions were used for first level; automated auditory brainstem response for second level. Second level included children with a "refer" response at first level and babies with a family history for hearing loss or other risk factors. Hearing loss diagnosis was made using clinical auditory brainstem response. RESULTS During first level, 254 (5.4% ) newborns were "refer". At retest, 130 (51.1% ) babies were PASS and 48 (18.8% ) were "refer". 76 babies dropped out (29.9% ). 146 babies (3.1% ) were referred to the second level: 48 for a "refer" response at first level and 98 for a PASS response but potential hearing loss due to risk factors. 24 babies dropped out (16.4% ). Out of 122 newborns tested in the second level, 105 (86.1% ) had a PASS response and 17 (13.9% ) were "refer". Our screening protocol identified 7 (0.14% ) babies with profound hearing loss; 5 had unilateral and 2 had bilateral hearing loss. 2 babies dropped out at diagnostic level (11.8% ). CONCLUSIONS A correct and early diagnosis of hearing loss is mandatory to prevent permanent consequences; the spread of hearing screening programs is the optimal solution to reach this goal.

Abstract
Background and Objectives Despite the extensive research for the Meniere’s disease (MD), it’s pathophysiology still remains uncertain and questionable among scientists. Clinical symptoms and audiometric tests form the basis for the diagnosis. Nevertheless the differential diagnosis can be extremely challenging, due to subjective and not specific results. Incorrect diagnosis is most likely and for this reason there is a great demand for objective and reliable tests. Subjects and Methods The presence of endolymphatic hydrops is necessary condition but non enough for the diagnosis. In this study we analyze retrospectively the summating potentials (SP)/action protentials (AP) ratio from peritympanic electrocochleography in 34 patients,divided in two groups (13 patients classified as defined MD and 21 patients classified as probable MD). The purpose was to identify the utility of the exam so to be able to achieve an early defined diagnosis. Furthermore our intention was to obtain an objective test, besides the clinical criteria currently in use for the diagnosis and the classification of the MD. Results The analysis of the SP/AP results shows high predictability for the MD (positive in six out of seven cases with a sensitivity greater than 80%). Conclusions Our study demonstrates a satisfactory sensibility percentage in recurrent defined MD presentation (>80%). Early identification of MD can lead to an early treatment and control of the progression of the disease. Furthermore it could be a valuable instrument for the follow up and evaluation of the patients classified as probable MD in accordance with the criteria of the American Academy of Otolaryngology-Head and Neck Surgery (1995).

Abstract
BACKGROUND To report our initial clinical experience of helical tomotherapy (HT) in the treatment of locally advanced oropharynx and inoperable oral cavity cancer. METHODS Between February 2008 and January 2011, 24 consecutive patients, 15 with oropharyngeal cancer and 9 with oral cavity cancer were treated with exclusive radiotherapy or concomitant chemoradiotherapy. Simultaneous integrated boost (SIB) in 30 fractions scheme was prescribed to all patients, using Helical Tomotherapy. Doses administered to primary tumor, oropharynx/oral cavity and positive lymph-nodes and negative lymph-nodes were 66-67.5 Gy, 60-63 Gy and 54 Gy, respectively. RESULTS Complete response rate for the oropharynx and the oral cavity group was 86.7% and 77.8%, respectively. The 1 and 2-year Overall Survival (OS) and Disease Free Survival (DFS) rate for the oropharynx group was 92.9%, 85.1%, 92.9% and 77.4% respectively. For the oral cavity group, 1 and 2-year OS and DFS rates were 55.6%, 55.6%, 75% and 75%, respectively. No patient developed grade ≥3 mucositis, dysphagia or dermatitis. The maximum late-toxicity grade observed was 2, for all the variables examined. CONCLUSIONS HT appears to achieve encouraging clinical outcomes in terms of response, survival and toxicity rates.

Use of pJANUS-02-001 as a calibrator plasmid for Roundup Ready soybean event GTS-40-3-2 detection: an interlaboratory trial assessment. Anal Bioanal Chem 2010; 396:2165-73.

Abstract
Owing to the labelling requirements of food and feed products containing materials derived from genetically modified organisms, quantitative detection methods have to be developed for this purpose, including the necessary certified reference materials and calibrator standards. To date, for most genetically modified organisms authorized in the European Union, certified reference materials derived from seed powders are being developed. Here, an assessment has been made on the feasibility of using plasmid DNA as an alternative calibrator for the quantitative detection of genetically modified organisms. For this, a dual-target plasmid, designated as pJANUS-02-001, comprising part of a junction region of genetically modified soybean event GTS-40-3-2 and the endogenous soybean-specific lectin gene was constructed. The dynamic range, efficiency and limit of detection for the soybean event GTS-40-3-2 real-time quantitative polymerase chain reaction (Q-PCR) system described by Terry et al. (J AOAC Int 85(4):938-944, 2002) were shown to be similar for in house produced homozygous genomic DNA from leaf tissue of soybean event GTS-40-3-2 and for plasmid pJANUS-02-001 DNA backgrounds. The performance of this real-time Q-PCR system using both types of DNA templates as calibrator standards in quantitative DNA analysis was further assessed in an interlaboratory trial. Statistical analysis and fuzzy-logic-based interpretation were performed on critical method parameters (as defined by the European Network of GMO Laboratories and the Community Reference Laboratory for GM Food and Feed guidelines) and demonstrated that the plasmid pJANUS-02-001 DNA represents a valuable alternative to genomic DNA as a calibrator for the quantification of soybean event GTS-40-3-2 in food and feed products.
