ABSTRACT

BACKGROUND: Oral floor ranulas are pseudocysts located in the floor of the mouth that result from the extravasation of mucus from a sublingual gland. Historically, there has been little consensus on the ideal first-line treatment. Currently, definitive treatment involves sublingual gland excision, which can injure the lingual nerve and submandibular duct. Minimally invasive surgical techniques have been proposed, but so far have been associated with a high rate of recurrence. METHODS: The so-called piercing-stretching suture technique was performed in 14 naïve adult and paediatric patients (6 females, with a mean age of 20.3 years (range, 7-55 years)). Clinical and ultrasonographic evaluations were performed in all patients; post-operative sialendoscopy was conducted in two paediatric patients. RESULTS: The surgical procedure was successful in all patients, and complete recovery of the ranula was seen in all but one of the patients who underwent suture replacement. No major or minor complications were encountered. CONCLUSION: This minimally invasive procedure may be considered a reliable and first-line treatment for management of simple oral floor ranulas.

ABSTRACT

OBJECTIVE: This study aimed to compare treatment outcomes in patients with laryngeal and tracheal stenosis treated during and prior to the coronavirus disease 2019 pandemic period. METHOD: Patients treated for laryngotracheal lesions with impending airway compromise during the active pandemic period were matched with those treated for similar lesions in the preceding years in a monocentric tertiary hospital setting. RESULTS: During the pandemic period of 55 days, 31 patients underwent 47 procedures. Seven patients (2 children, 5 adults) had open airway surgery, and one had an operation-specific complication. Twenty-four patients (10 children, 14 adults) underwent 40 endoscopic interventions without any complications. Operation specific results during and prior to the pandemic were comparable. CONCLUSION: The management strategy in patients with laryngotracheal lesions and impending airway compromise should not be altered during periods of risk from coronavirus disease 2019. Avoiding a tracheostomy by performing primary corrective surgery or proceeding with a definitive decannulation would be beneficial in these patients to reduce the risk of contagion.

ABSTRACT

Interleukin 10 (IL-10) is an antiinflammatory cytokine, but also promotes B cell responses and plays a pathogenic role in systemic lupus erythematosus (SLE). CD4+CCR6+IL-7R+T cells from human tonsils produced IL-10 following stimulation by naïve B cells, which promoted B cell immunoglobulin G (IgG) production. These tonsillar CCR6+B helper T cells were phenotypically distinct from follicular helper T (TFH) cells and lacked BCL6 expression. In peripheral blood, a CCR6+T cell population with similar characteristics was identified, which lacked Th17- and TFH-associated gene signatures and differentiation-associated surface markers. CD4+CCR6+T cells expressing IL-10, but not IL-17, were also detectable in the spleens of cytokine reporter mice. They provided help for IgG production in vivo, and expanded systemically in pristane-induced lupus-like disease. In SLE patients, CD4+CCR6+IL-7R+T cells were associated with the presence of pathogenic anti-dsDNA (double-stranded DNA) antibodies, and provided spontaneous help for autoantibody production ex vivo. Strikingly, IL-10-producing CCR6+T cells were highly abundant in lymph nodes of SLE patients, and colocalized with B cells at the margins of follicles. In conclusion, we identified a previously uncharacterized population of extrafollicular B helper T cells, which produced IL-10 and could play a prominent pathogenic role in SLE.

ABSTRACT

INTRODUCTION: Bartolomeo Vivarini (Venezia 1432c.-Venezia 1499c.) was an Italian painter during the Renaissance. The artist was widely influenced by Andrea Mantegna, whose opera was characterized by personages with anatomical details meticulously described. MATERIALS AND METHODS: Some of the most valued paintings of Bartolomeo Vivarini were analyzed. Purpose of the present article is to describe these artworks focusing on female personages represented with thyroid swelling. RESULTS: A recurring female model in Vivarini's artworks is portrayed with a goitrous neck. This might display a real prevalence of thyroid diseases among young women in the Renaissance age (e.g. postpartum thyroiditis). CONCLUSIONS: Representation of goiter in the artworks of Vivarini and Mantegna reflects the increased anatomic accuracy and knowledge developed in art since Renaissance and Baroque.

ABSTRACT

After the first experiences with the Barbed Sutures (BS) in sleep surgery, we present the Modular Barbed Anterior Pharyngoplasty (M.B.A.Ph.), a functional tenso-structural reconstruction of the soft palate, as a surgical solution for Obstructive Sleep Apnea (OSA) due to antero-posterior collapse at the drug induced sleep endoscopy (DISE) for snoring and mild-moderate OSA. The action of the BS is sustained over time by means of solid and stable tissue scarring. M.B.A.Ph. avoids palatal fibromuscular resection and minimize iatrogenic bleeding (bloodless surgery). The technique is described in detail and some preliminary results are presented.

ABSTRACT

Some considerations will be expressed in consideration of the commentary previously published. In particular, we underline that no other medications were administered to the patients during the study period and any clinical evaluation was postponed in case of acute upper respiratory tract infection in the previous 14 days. We strongly advocate antibiotic treatment during any acute otitis media episode, and we agree that topically administered hyaluronic acid should be considered as a supporting treatment, "complementary to traditional therapies" in children with recurrent disease.

ABSTRACT

OBJECTIVES: To evaluate the effectiveness of interventional sialendoscopy alone or combined with outpatient intraductal steroid irrigations in patients with sialadenitis due to Sjögren's syndrome (SS). DESIGN: A pilot therapeutic study. SETTING: ENT Clinics, Universities of Milan and Pavia. STUDY POPULATION: We included 22 patients with SS of whom 12 underwent interventional sialendoscopy followed by intraductal steroid irrigations (group A), and 10 interventional sialendoscopy alone (group B). OUTCOMES MEASURES: The following outcome measures were considered and recorded before and after the therapeutic intervention: (i) number of episodes of glandular swelling, (ii) cumulative prevalence of patients with glandular swelling assessed by the specific domain, the EULAR SS Disease Activity Index (ESSDAI), (iii) severity of pain by means of a 0-10 pain visual analogue scale (VAS), (iv) severity of xerostomia and other disease symptoms assessed by the EULAR SS Patient Reported Index (ESSPRI) and the Xerostomia Inventory questionnaire. RESULTS: The postoperative reduction in the mean number of episodes of glandular swelling was 87% (95% CI: 77-93) and 75% (95% CI: 47%-88%) in the groups A and B, respectively. The percentage of patients with glandular swelling decreased from 41.7% to 0.0% in the group A and from 30.0% to 0.0% in the group B, respectively. Most of the patients experienced a subjective clinical improvement documented by the statistically significant reductions in the postoperative mean pain VAS (group A P<.001; group B P=.004), Xerostomia Inventory (P<.001 and P=.003) and ESSPRI scores (P<.001 and P=.008). Interventional sialendoscopy followed by outpatient intraductal steroid irrigations was more effective than interventional sialendoscopy alone, when pain VAS, Xerostomia Inventory and ESSPRI scores before and after treatment were analysed together using the multivariate Hotelling T2 test (P=.0173). CONCLUSIONS: This pilot study confirms that interventional sialendoscopy with steroid duct irrigation significantly reduces the number of painful episodes of sialadenitis and improves the subjective sensation of oral dryness and other disease symptoms in patients with SS. The study results also suggest that the improvement is greater when interventional sialendoscopy is combined with a cycle of outpatient steroid ductal irrigations. Larger controlled randomised studies are certainly needed to confirm these preliminary data.

ABSTRACT

OBJECTIVES: The aim of this study was to demonstrate in a prospective multicentre study that Barbed Reposition Pharyngoplasty (BRP) procedure is safe and effective in management of obstructive sleep apnoea/hypopnea syndrome (OSAHS) patients. DESIGN: Prospective study. SETTING: Multicentre study. PARTICIPANTS: Patients suffering from obstructive sleep apnoea. MAIN OUTCOMES MEASURES: Values of postoperative apnoea-hypopnea index (AHI), oxygen desaturation index (ODI), epworth sleepiness scale (ESS). RESULTS: 111 Barbed Reposition Pharyngoplasty procedures standing alone or as a part of multilevel surgery for OSAHS, performed between January and September 2016, were analysed in 15 different centres. The average hospitalisation period was 2.5 ± 0.5 days. The mean patient age was 46.3 ± 10.5 years. The average body mass index at the time of the procedure was 27.9 ± 3.2, and the majority of the patients were men (83%). The mean preoperative and postoperative apnoea/hypopnea index was 33.4 ± 19.5 and 13.5 ± 10.3, respectively (P < .001). The mean preoperative and postoperative ESS score was 10.2 ± 4.5 and 6.1 ± 3.6, respectively (P < .001). The mean preoperative and postoperative ODI were 29.6 ± 20.7 and 12.7 ± 10.8, respectively (P < .001). CONCLUSIONS: Patients undergoing BRP standing alone or as part of a multilevel approach for the treatment of OSAHS have a reasonable expectation for success with minimal morbidity.

ABSTRACT

Follicular helper T cells (TFHs) are a key component of adaptive immune responses as they help antibody production by B cells. Differentiation and function of TFH cells are controlled by the master gene BCL6, but it is largely unclear how this transcription repressor specifies the TFH program. Here we asked whether BCL6 controlled helper function through down-regulation of specific microRNAs (miRNAs). We first assessed miRNA expression in TFH cells and defined a TFH-specific miRNA signature. We report that hsa-miR-31-5p (miR-31) is down-regulated in TFH; we showed that BCL6 suppresses miR-31 expression by binding to its promoter; and we demonstrated that miR-31 inhibits the expression of molecules that control T-helper function, such as CD40L and SAP. These findings identify a BCL6-initiated inhibitory circuit that stabilizes the follicular helper T cell program at least in part through the control of miRNA transcription. Although BCL6 controls TFH activity in human and mouse, the role of miR-31 is restricted to human TFH cell differentiation, reflecting a species specificity of the miR-31 action. Our findings highlight miR-31 as a possible target to modulate human T cell dependent antibody responses in the settings of infection, vaccination, or immune dysregulation.

ABSTRACT

The traditional management of obstructive salivary disorders has been replaced by minimally-invasive gland-preserving techniques including shock-wave lithotripsy, sialendoscopy, interventional radiology and endoscopically video-assisted trans-oral and cervical stone retrieval, of which sialendoscopy is considered to be the method of first choice. Primary endoscopically controlled stone extraction without prior fragmentation is only possible in 15-20% of cases; in more than 80%, fragmentation is necessary because of the size, impactation and location of the stone, or an alternative treatment such as transoral duct surgery or combined approaches are required. Moreover, about 10-20% of all stones cannot be adequately accessed by means of a sialendoscope or any alternative surgical method and, in such cases, extra-corporeal shock wave lithotripsy (ESWL) is the treatment of choice. However, in endoscopically accessible stones, ESWL is being gradually replaced by endoscopically assisted intra-corporeal techniques, including endoscopically guided laser and pneumatic intracorporeal lithotripsy. We describe the currently most widely used techniques for salivary lithotripsy, including ESWL, and endoscopically guided laser, electrohydraulic, electrokinetic and pneumatic intra-corporeal lithotripsy, and discuss their indications given the widespread use of advanced rehabilitative sialendoscopy and combined therapeutic approaches.

ABSTRACT

Salivary gland toxicity is a common adverse effect of radioactive iodine (131I) for the treatment of thyroid cancers with a prevalence ranging from 2% to 67% of the 131I exposed population. Recently, sialendoscopy has been introduced as an attractive diagnostic and therapeutic tool for management of patients with radioiodine-induced sialadenitis that is unresponsive to standard medical treatments. The objective of the current review was to assess the impact of this procedure on outcomes in patients suffering from radioiodine sialadenitis. Overall, eight studies were included and 122 patients underwent 264 sialendoscopic procedures. Duct stenosis and mucous plugs were observed in 85.7% of endoscopic findings, supporting the role of ductal obstruction in the pathophysiology of radioiodine sialadenitis. In total, 89.3% of patients experienced complete or partial resolution of sialadenitis recurrences without any major adverse events, and parotidectomy was advocated in only 1 case. However, outcomes mainly concerned subjective reports and only two clinical experiences evaluated objective measurement with dissimilar results. Limited to few studies, xerostomia and obstructive symptoms responded differently after sialendoscopy. The optimal timing of salivary gland videoendoscopy needs to be further analysed in order to define the best management of radioiodine-induced obstructive sialadenitis.

ABSTRACT

It has been suggested that a conservative trans-oral approach to proximal and hilo-parenchymal submandibular stones (HPSMS) is a valid alternative to the more frequently used sialadenectomy. The aim of this study was to evaluate the surgical, ultrasonographic and patients' subjective outcomes of results of the trans-oral removal of HPSMS. Between January 2003 and September 2015, sialendoscope-assisted trans-oral surgery was used to remove symptomatic, large (> 7 mm), fixed and palpable HPSMS from 479 patients under general anaesthesia. All patients were followed clinically and ultrasonographically to investigate symptom relief and recurrence of stones, and were telephonically interviewed to assess saliva-related subjective outcomes with a questionnaire. Stones were successfully removed from 472 patients (98.5%); the seven failures (1.5%) concerned pure parenchymal stones. One year after the procedure, 408 patients (85.1%) were symptom free, 59 (12.3%) had recurrent obstructive symptoms and 12 (2.6%) had recurrent infections. Of the 54 patients who developed a recurrent stone (11.2%), 52 underwent a second procedure: 29 interventional sialendoscopies, two sialendoscope-assisted intra-corporeal pneumatic lithotripsy, eight secondary transoral surgery to remove residual stones, six a cycle of extra-corporeal lithotripsy and seven submandibular sialadenectomy. Most patients (75.2%) reported mild surgery-related pain. The symptoms of 454 patients (94.8%) improved after adjunctive treatment and, at the end of follow-up, the affected gland was preserved in 98.5% of patients. A sialendoscope-assisted trans-oral removal of large HPSMS is a safe, effective, conservative surgical procedure, and functional preservation of the main duct and parenchyma of the obstructed gland allows sialendoscopic access through the natural ostium in case of recurrence. Combining a trans-oral approach with other minimally invasive, conservative procedures ensures symptomatic relief and salivary duct system clearance in the majority of patients.

ABSTRACT

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

ABSTRACT

Hyaluronic acid (HA) is involved in modulating inflammatory airway processes and mucociliary clearance. Some studies have tested the effectiveness of the topical administration of HA in patients with upper airway diseases with positive preliminary results. A prospective, single-blind, 1:1 randomised controlled study was performed to assess the efficacy and safety of the daily topical administration of 9 mg of sodium hyaluronate in 3 mL of a 0.9 % sodium saline solution on the basis of endoscopic and clinical parameters in children with chronic adenoiditis associated with recurrent acute otitis media and otitis media with effusion; age- and gender-matched children receiving normal 0.9 % sodium chloride saline solution were used as controls. Analysis was based on 103 (mean age 63.3 ± 18.2 months; 52 males, 50.5 %) children: 54 in the study group and 49 in the control group. A statistically significant reduction in the mean number of all acute otitis media episodes (AOME) (mean reduction 0.8 ± 0.4 per month; p value 0.05) and AOME without tympanic membrane perforation (mean reduction 0.6 ± 0.3 per month; p value 0.04) after recruitment was documented only in the study group. HA significantly improved all the endoscopic outcomes (p values ranging between 0.05 and <0.01) but one. Nasal washing with saline solution was effective on only three of them (p values ranging between 0.03 and <0.01). No untoward effects were documented. Our results confirm the safety and document the positive effect of topically administered HA solution on children with chronic adenoiditis associated with middle ear disease.

ABSTRACT

OBJECTIVES: To verify the role of interventional sialendoscopy and steroidal ductal irrigation in patients with recurrent sialadenitis. DESIGN: A prospective, cross-sectional pilot study. SETTING: University of Milan. PARTICIPANTS: Fifty-four patients with sine causa recurrent sialadenitis who underwent interventional sialendoscopy (group A, 36 patients) or interventional sialendoscopy followed by a intraductal steroidal irrigations (group B, 18 patients). MAIN OUTCOMES MEASURES: The number of episodes of sialadenitis three and 6 months before and after sialendoscopy, and their severity assessed by means of a 0-10 pain visual analogue scale. RESULTS: In the population as a whole, a significant post-treatment reduction in the number of episodes of 30.7 ± 5.5 after 3 months and 34.6 ± 10.2 after 6 months (P < 0.001) and a significant reduction in pain visual analogue scale values of 4.7 ± 0.4 after 6 months (P < 0.001) occurred. There was a statistically significant reduction in both parameters at the same time points in both treatment groups (P ≥ 0.001), with no significant between-group difference in pain visual analogue scale values, an albeit non-significant trend in favour of group B in terms of the number of episodes 3 months after therapy that became significant after 6 months (11.0 ± 9.9 versus 20.5 ± 9.5; P = 0.05). CONCLUSIONS: Interventional sialendoscopy is effective for the treatment of recurrent sialadenitis; the addition of intraductal steroidal irrigations seems to increase its value in the medium term. Further studies of larger case series with longer follow-up are needed to establish the possibly primary role of steroid therapy in blocking inflammation.

ABSTRACT

Recently, reduced Nasal nitric oxide (nNO) nNO levels have been reported in children with adenoidal hypertrophy predisposing to chronic nasosinusal inflammation. Given the strict anatomic and physiopathologic link between the nasopharyngeal and middle ear compartments, and considering the high prevalence of otitis prone children among those affected with chronic adenoiditis, we designed a study aimed to test any possible difference in nNO levels between non-allergic children with and without recurrent acute otitis media (RAOM) associated with chronic adenoiditis. The study involved 54 children with RAOM (44.4% males; mean age= 7.5±3.5 years) and 51 children without RAOM (47.4% males; mean age= 7.0±3.8 years). nNO levels were significantly reduced in children with RAOM compared to children without RAOM (676.9±250.7 ppb vs 831.8±320.4 ppb, respectively; p= 0.02). Our results could be related to reduced NO production by the ciliated paranasal, nasopharyngeal and middle ear epithelium and the impaired sinusal ostial and Eustachian tube patency due to chronic inflammation, and seem to confirm the involvement of NO pathway in recurrent upper airway infections related to impaired ciliated respiratory mucosa.

ABSTRACT

The purpose of this investigation was to describe the first application of nasopharyngeal cytology (NPC), a new cytological technique to collect cellular material from the nasopharyngeal surface non-invasively in children with chronic adenoiditis associated with recurrent acute otitis media and/or otitis media with effusion. Cellular material was collected transorally using an extra-thin flexible wire nasopharyngeal swab and then examined under a light microscope. The diagnostic accuracy of NPC in detecting the presence of allergy and pathogens (compared to microbiological evaluation of nasopharyngeal aspirates, NPAs) was assessed. NPC was performed on 121 children (mean age 69.4 ± 15.5 months). Inflammatory cells and pathogens were detected in 61.1 % and 44.2 % of patients, respectively. The specificity of nasopharyngeal eosinophils in detecting allergy was good (91.9 %), as was the specificity of mast cells, but the sensitivities were less. The NPAs revealed bacterial colonisation in 84.7 % of the patients, and Streptococcus pneumoniae was the most frequently isolated (60.0 %). NPC revealed the presence of bacteria in 94.9 % of patients, including bacillary species in 33.9 %. NPC was highly sensitive in detecting pathogens (96.0 %). Its specificity in detecting bacillary species was fairly good (75.0 %), but the corresponding values of the specificity of NPC in detecting pathogens and its sensitivity in detecting bacillary species were poor. Our findings suggest the need for more structured studies that can test the real effectiveness and usefulness of NPC in defining nasopharyngeal cytological patterns in children with chronic nasopharyngeal diseases by comparing it with established diagnostic techniques.
