Objectives: Salivary gland ultrasound (SGUS) has an interest in primary Sjögren's disease (pSD) for diagnosis, but the evolution of parenchymal lesions over time is unknown. The objective of this study was to assess the severity of ultrasound abnormalities in relation to pSD duration from the time of buccal dryness onset., Methods: In this cross-sectional international multicentre study, patients with pSD according to the 2002 or 2016 ACR/EULAR classification criteria were included. Parenchymal abnormalities were classified according to the semiquantitative score as defined by OMERACT. Patients were separated into 4 groups (Group A: < 5 years, Group B: 5-9 years, Group C: 10-20 years, and Group D: > 20 years from the onset of buccal dryness). The association between disease duration groups and SGUS lesions was quantified in terms of odds ratios and 95% confidence intervals., Results: A total of 247 patients were consecutively included between May 2019 and February 2022. Eighty-nine percent of patients had a focus score ≥1/4 mm2, and 85% had positive anti-Ro/SSA. pSD duration was associated with a pathological OMERACT score (score 2 or 3): OR for 5-year duration: 1.23 [95% CI 1.04; 1.47], p= 0.0383). Considering each US item, the only statistical association with pSD duration was found regarding the presence of hyperechoic bands (25% or more): OR for five-year duration 1.18 [95% CI 1.03; 1.36], p= 0.038), independent of an older age., Conclusion: pSD duration was associated with the presence of hyperechoic bands, but not with hypoechoic areas, suggesting a progressive fibro-adipose evolution., (© The Author(s) 2024.

Introduction: Salivary gland tumor operations are associated with complications including facial nerve dysfunction (FND) and salivary fistula. The objective of this study was to investigate the effect of extracapsular dissection (ECD) and the application of Clostridium botulinum toxin (CBT) in contrast to partial and lateral parotidectomy on complications. Methods: All salivary gland tumor operations performed within the last 6 years were retrospectively examined. Data were collected from electronic patient files from our otorhinolaryngology clinic. Total parotidectomies and submandibulectomies were not included in the analysis of CBT application. Results: In total, 418 cases were examined, including 84 (20%) malignant tumors. In total, 18 patients underwent ECD, 93 partial parotidectomy, 199 lateral parotidectomy, 76 total parotidectomy, and 32 submandibulectomy. The most common complication was transient FND (49%; n = 205; data available for 415 patients), which was measured at four days. Additional complications included salivary fistula ( n = 56), infection ( n = 49), bleeding or hematoma ( n = 21). Preoperative facial nerve paralysis ( p < 0.0001), pain ( p < 0.0001), and a history of squamous cell skin carcinoma (SCC) ( p < 0.001) were predictive of malignancy. The application of CBT did not reduce the risk of salivary fistula ( p -value: 0.0182) and was associated with a higher combined complication rate ( p -value: 0.0199). ECD was not associated with a lower likelihood for FND ( p = 0.350). Conclusions: Preoperative pain, facial paralysis, or a history of SCC are predictors of malignancy. Use of CBT was not associated with a reduced risk of salivary fistula, but rather a higher complication rate.

Background: Diced cartilage (DC) plays an integral role in rhinoplasty, and its application is well established in nasal dorsal augmentation rhinoplasty as a diced cartilage framework (DCF)., Methods: Fifteen patients requiring nasal dorsal augmentation were included. Two different types of DCF were applied: DC wrapped in fascia lata or Lyomesh® and DC embedded in platelet-rich fibrin (PRF). Postoperative ultrasound follow-ups were performed at intervals of one month, three months, and one year after surgery using a high-frequency linear ultrasound transducer. The aim was to depict the viability of the DCF in vivo., Results: DCF was successfully depicted using ultrasound imaging in all 15 patients. Ultrasound rendered DC as hypoechoic and inhomogeneous areas. Perifocal hypoechoic edema was detected, which significantly decreased by the one-year follow-up. During the one-year postoperative period, very little DC had decreased in diameter and the framework was fully intact, with no signs of migration. On high-frequency ultrasound, DC wrapped in fascia lata or Lyomesh® appeared as a hypoechoic and inhomogeneous area clearly limited by a thin hyperechoic envelope material, whereas DC embedded in PRF presented as a hypoechogenic area that spread laterally along the bone and nasal cartilage on both sides. Using color Doppler imaging, neovascularization of the DCF was identified in 7 of 15 patients at the postoperative examination., Conclusion: High-resolution ultrasound is an accurate, non-invasive imaging method appropriate for visualizing DCF in augmentation rhinoplasty. Additionally, it is possible to detect nascent neovascularization within grafts by using color Doppler imaging., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Introduction: Currently, the diagnosis of salivary gland tumors using imaging techniques is unreliable., Methods: In this monocentric retrospective study, we examined patients who received a 68 Ga-DOTATOC PET/CT and subsequently underwent a salivary gland tumor resection between 1 January 2010 and 31 December 2021. PET/CT image assessment was compared with somatostatin receptor (SSTR) expression and histology., Results: Thirteen patients (five pleomorphic adenoma (PA) and eight other parotid lesions (OPL)) received a 68 Ga-DOTATOC PET/CT. Imaging displayed strong focal tracer uptake in all PA except for one with strong tumor to background discrimination. PA revealed higher SUVmax, SUVmean, liver and blood pool quotients than those of Warthin tumors (WT) and of OPL. In comparison to the contralateral parotid, SUVmax ( p = 0.02), SUVmean ( p = 0.02), liver quotient ( p = 0.03) and blood pool quotient ( p = 0.03) were all significantly higher. In contrast, WT and OPL showed in relation to the contralateral parotid no significant differences of SUVmax (WT p = 0.79; OPL p = 0.11), SUVmean (WT p = 1.0; OPL p = 0.08), liver quotient (WT p = 0.5; OPL p = 0.08) and blood pool quotient (WT p = 0.8; OPL p = 0.19). Two PA and one granuloma were not available for examination. In the immunohistochemal analysis, all PA demonstrated the highest intensity of SSTR2 expression (grade 3). Furthermore, PA had a high percentage of cells expressing SSTR2 (20%, 80% and 55%)., Conclusions: A strong tracer uptake in PA was shown in 68 Ga-DOTATOC PET/CT. This may allow physicians to utilize radioligated somatostatin analogue PET CT/MR imaging to accurately diagnose PA. Additionally, it may be possible in the future to treat the PA with a noninvasive peptide receptor radionuclide therapy or with somatostatin analogues.

Background: While retinal vessel changes are evident in the eyes of patients with relapsing-remitting multiple sclerosis (RRMS), changes in the vasculature of possible MS mimics such as primary Sjögren's syndrome (pSS) remain to be determined. We investigated the potential of retinal optical coherence tomography (OCT) angiography (OCTA) as diagnostic tool to differentiate between patients with RRMS and pSS., Methods: This cross-sectional study included patients with RRMS (n = 36), pSS (n = 36) and healthy controls (n = 30). Participants underwent clinical examination, assessment of visual acuity, retinal OCT, OCTA, and serum markers of glial and neuronal damage. We investigated the associations between OCTA parameters, visual functions, and serum markers. Eyes with a history of optic neuritis (ON) were excluded from analysis., Results: We observed a significant thinning of the combined ganglion cell and inner plexiform layer in the eyes of patients with RRMS but not with pSS, when compared to healthy controls. Retinal vessel densities of the superficial vascular complex (SVC) were reduced in both patients with RRMS and pSS. However, retinal vessel rarefication of the deep vascular complex (DVC) was only evident in patients with pSS but not RRMS. Using multivariate regression analysis, we found that DVC vessel loss in pSS patients was associated with worse visual acuity., Conclusions: Compared to patients with RRMS, rarefication of deep retinal vessels is a unique characteristic of pSS and associated with worse visual function. Assuming a disease-specific retinal vessel pathology, these data are indicative of a differential affliction of the gliovascular complex in the retina of RRMS and pSS patients., (© 2024.

Introduction: Major salivary gland ultrasonography (SGUS) demonstrated its good metric properties as an outcome measure for diagnosing primary Sjögren's disease (SD). The objective was to assess SGUS reliability among sonographers with different levels of experience, using web training., Methods: Sonographers from expert centers participated in the reliability exercise. Before exercises, training was done by videoconferencing. Reliability of the two most experienced sonographers (MES) was assessed and then compared to other sonographers. Intra-reader and inter-reader reliability of SGUS items were assessed by computing Cohen's κ coefficients., Results: All sets were read twice by all 14 sonographers within a 4-month interval. Intra-reader reliability of MES was almost perfect for homogeneity, substantial for Outcome Measures in Rheumatology (OMERACT) scoring system (OMERACTss). Among LES (less experienced sonographers), reliability was moderate to almost perfect for homogeneity, fair to moderate for OMERACTss, and fair to almost perfect for binary OMERACTss. Inter-reader reliability between MES was almost perfect for homogeneity, substantial for diagnosis, moderate for OMERACTss, and substantial for binary OMERACTss. Compared to MES, reliabilities of LES were moderate to almost perfect for both homogeneity and diagnosis, only fair to moderate for OMERACTss, but increased in binary OMERACTss., Conclusions: Videoconferencing training sessions in an international reliability exercise could be an excellent tool to train experienced and less-experienced sonographers. SGUS homogeneity items is useful to distinguish normal from abnormal salivary glands parenchyma independently of diagnosis. Structural damage evaluations by OMERACT scoring system is a new comprehensive score to diagnose patients with SD and could be easily used by sonographers in a binary method., (© 2024.

Background: Training in clinical ultrasound has become highly relevant for working as an otorhinolaryngologist. While there is a high demand for standardized and certified training courses, until recently, there was no possibility to attend web-based and exclusively virtual head and neck ultrasound courses certified by the Deutsche Gesellschaft für Ultraschall in der Medizin (DEGUM; German Society for Ultrasound in Medicine)., Objective: The aim of this study was to provide a qualitative and semi-quantitative analysis of the first purely virtual DEGUM-certified head and neck ultrasound courses., Materials and Methods: In 2021, three purely web-based DEGUM-certified head and neck ultrasound courses were carried out and then qualitatively analyzed using questionnaires including an examination., Results: The purely virtual implementation of head and neck ultrasound courses proved to be a viable alternative to the conventional course format, with a high level of acceptance among the participants. The lack of practice among the participants remains a relevant criticism., Conclusion: A more dominant role of web-based and remote ultrasound training is likely and should be considered as an alternative depending on existing conditions. Nevertheless, acquisition of practical sonographic skills remains a major hurdle if courses are purely digital., (© 2024. The Author(s).)

Purpose: Different pathologies of the submandibular gland are an indication of submandibular gland excision-ranging from inflammatory causes and sialolithiasis to malignant tumors. The purpose of this study was to get an overview of the different indications for submandibular gland excision. Methods: The main goal of this study was to evaluate the different indications for submandibular gland excision during a 20-year period. In addition, epidemiological information and therapy concepts were investigated with a special focus on Tumor Lymph nodes Metastasis (TNM) classification and recurrence rate. Procedures during which the submandibular gland was removed while not being the primary cause for surgery (eg, neck dissection in Level Ib) were not included. Results: During the period of observation, 359 submandibular gland excisions were performed. The most common cause for submandibular gland excision was sialolithiasis (n = 129) with intraparenchymal stone localization. Up next were inflammatory causes (n = 115) in particular chronic submandibular sialadenitis followed by only a few cases of Sjögren's syndrome, sarcoidosis, and tuberculosis. In 115 cases, surgery was performed for tumors of the submandibular gland, with 88 of them being benign and 27 malignant. Malignancies were then divided into lymphomas (n = 9) and primary salivary gland malignancies (n = 18). Conclusion: This retrospective study of a large cohort of patients displays a representative overview of the indications for submandibular gland excision. Sialolithiasis was the most common underlying cause of gland excision. The malignancy rate in our cohort was lower than described in the literature., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: If not eliminated by the immune system and persisting over years, oropharyngeal high-risk HPV infection can lead to cancer development in the oropharynx. HPV infection is very commonly found in the genital region and can serve as an HPV reservoir. In this study, we investigate whether women with a genital HPV infection are at a higher risk of harboring an undetected oropharyngeal HPV infection via genital-oropharyngeal transmission., Methods: Women presenting for routine gynecological checkups were included in this study. All participants received an HPV brush test from the genital region as well as from the oropharynx. Additionally, probable risk factors for an HPV infection were assessed in a structured questionnaire., Results: 142 women were included in this study. The rate of oropharyngeal HPV infection was low with 2/142 (1,4%) women positive for a low-risk HPV genotype. In the genital brush test, 54/142 (38%) women were tested HPV positive of which 41/142 (29%) were positive for a high-risk HPV genotype., Conclusions: The rate of an oropharyngeal HPV detection in our population was low with 2/142 women harboring a low-risk HPV infection., (© 2023.

Background: Fabry disease (FD) is one of the X‑linked lysosomal storage diseases that can affect any organ. They have a specific lysosomal dysfunction in common, which results in substrate accumulation in lysosomes instead of metabolite degradation. Due to the deficiency/absence of α‑galactosidase, globotriaosylceramides (Gb3) are deposited in lysosomes of the organs. In addition to acroparesthesia, angiokeratomas, autonomic dysfunction, vortex keratopathies, ischemic cerebral or cardiac complications and chronic renal failure, also vestibulocochlear dysfunctions with sudden or progressive asymmetric hearing loss, tinnitus and vertigo may be observed., Patients and Methods: In this retrospective study, 33 patients (men = 16 and women = 17) with FD were evaluated. All patients presented to us in interdisciplinary cooperation as part of routine examinations by the specialized center for lysosomal storage diseases of the in-house department of nephrology. This presentation is carried out as a screening examination independent of neuro-otological symptoms., Results: The mean age at diagnosis was 34.76 (±11.55) years. The first presentation in our ENT department was at 40.45 (±11.71) years. We were able to demonstrate a significant correlation between neurological symptoms or apoplexy and hearing loss (p = 0.001) and between cardiac manifestations and hearing loss (p = 0.024)., Conclusion: Hearing loss is a potential symptom of Fabry disease and is not limited to the classic male phenotype. Due to possible positive correlations with neurological and cardiological manifestations of the disease, routine ENT screening examinations should be carried out to be able to identify and treat neuro-otological deficits at an early stage. In addition, FD should also be considered and tested as a differential diagnosis, especially in younger patients with sudden unilateral or bilateral hearing loss and a family history., (© 2023.
