Trigeminal Sensitivity in Patients With Allergic Rhinitis and Chronic Rhinosinusitis

alexandrossfakianakis shared this article with you from Inoreader Trigeminal Sensitivity in Patients With Allergic Rhinitis and Chronic Rhinosinusitis via The Laryngoscope Allergic patients react more sensitively to trigeminal stimuli in the nose than a comparable control group. This is important because it supports the suggestion that local factors in the nasal mucosa are significantly involved in influencing the trigeminal system of the nose. Objective Allergic rhinitis (AR) and chronic rhinosinusitis with nasal polyps (CRSwNP) are of high importance in otorhinolaryngology. Some of their symptoms are related to changes in the nasal trigeminal sensitivity. The aim of this study was to compare nasal trigeminal sensitivity in patients with AR, CRSwNP, and healthy controls (HC). Methods A total of 75 individuals participated (age 19–78 years; 34 AR, 10 CRSwNP and 31 HC). Olfactory function was determined using the extended Sniffin' Sticks test battery. Trigeminal sensitivity was assessed with CO2 detection thresholds. Trigeminal negative mucosal potentials (NMP) and EEG-derived event-related potentials (ERP) were recorded in response to selective olfactory (phenylethyl alcohol) and trigeminal (CO2) stimuli using high-precision air-dilution olfactometry. Results In comparison to HC, AR patients had lower CO2 thresholds, also reflected in shorter peak latencies in NMP and trigeminal ERP measurements. CRSwNP patients had a decreased sensitivity for trigeminal stimuli, also reflected in prolonged trigeminal ERP latencies, and reduced olfactory function compared to HC. Conclusion AR patients seemed to be more sensitive to trigeminal stimuli than CRSwNP patients. Importantly, the differences could be shown on psychophysical and electrophysiological levels. The changes in trigeminal sensitivity appear to be present already at the level of the respiratory epithelium. The differences between the two groups may depend on the specific inflammatory changes accompanying each disorder, the degree of inflammatory activity, or duration of the inflammatory disorder. However, because the sample sizes are relatively small, these results need to be confirmed in the future studies with larger groups. Level of Evidence 4 Laryngoscope, 2022 View on Web

Post‐induction lymph node delineation in nasopharyngeal cancer: A single‐center experience

alexandrossfakianakis shared this article with you from Inoreader Post‐induction lymph node delineation in nasopharyngeal cancer: A single‐center experience via Head & Neck Abstract Background We routinely delineate the gross tumor volume (GTV) for the lymph nodes (LN) based on post-induction chemotherapy (IC) MRI in nasopharyngeal carcinoma (NPC). Herein, we investigated the sufficiency of this method, particularly in high-risk LNs. Methods Eighty-one LNs with a high-risk of clinical extranodal extension and/or ≥3-cm diameter in 58 patients were evaluated. A new GTV covering the pre-IC LN volume was delineated for each LN. Results The median volume reduction was 72.5% for the GTV and 53.1% for the planning target volume. After a median 43 months, the overall LN local control rate was 97.5%. The 2- and 5-year LN recurrence-free survival, overall survival, and disease-free survival rate was 88.3% and 84.4%, 92.5% and 85.1%, and 86.8% and 79.2%, respectively. Conclusion IC yields a significant reduction in nodal target volumes, and post-IC nodal volume-based radiotherapy provides excellent LC in NPC, even in high-risk LNs. View on Web

Extended‐release naltrexone for people with alcohol use disorder on therapeutic anticoagulation: A case series

alexandrossfakianakis shared this article with you from Inoreader Extended‐release naltrexone for people with alcohol use disorder on therapeutic anticoagulation: A case series via Journal of Clinical Pharmacy and Therapeutics Guide to XR-NTX Discussion for Patients on Therapeutic Anticoagulation. Abstract What is known and objective Individuals with medication adherence challenges or a preference for long-acting medications may benefit from extended-release naltrexone (XR-NTX) for treatment of alcohol use disorder (AUD). Individuals on therapeutic anticoagulation were excluded from XR-NTX studies and its safety in this population has not been reported. Case summary We conducted structured retrospective chart review of six individuals who received XR-NTX for AUD while on therapeutic anticoagulation between November 2019 and Deccember 2020. We found no documented complications among six individuals who received up to 11 doses of XR-NTX while on therapeutic anticoagulation. What is new and conclusion XR-NTX may be safely tolerated by patients on therapeutic anticoagulation. We need larger studies evaluating XR-NTX administration in patients on therapeutic anticoagulation and those with coagulopathies, including individuals with alcohol-related liver disease, to better quantify risks and benefits for shared decision-making.

Facial implant gingival level and thickness changes following maxillary anterior immediate tooth replacement with scarf‐connective tissue graft: A 4–13‐year retrospective study

alexandrossfakianakis shared this article with you from Inoreader Facial implant gingival level and thickness changes following maxillary anterior immediate tooth replacement with scarf‐connective tissue graft: A 4–13‐year retrospective study via Journal of Esthetic and Restorative Dentistry Abstract Objective A scarf-shaped connective tissue graft can be placed at the facial and proximal aspect of the peri-implant soft tissue zone during immediate implant placement and provisionalization (IIPP) procedures in the esthetic zone to optimize implant esthetics without the need of flap reflection. This retrospective study evaluated soft tissue stability after scarf-connective tissue graft (S-CTG) in conjunction with IIPP procedures in the esthetic zone. Materials and Methods Patients who received IIPP with S-CTG with a minimum 1-year follow-up were evaluated. Mid-facial gingival level (MFGL) change and mid-facial gingival thickness (MFGT) change were measured and compared at the pre-op (T0), IIPP + S-CTG surgery (T1), follow up appointment with MFGT measurement (T2), and latest follow-up appointment (T3). Implant success rate and graft necrosis were also recorded. Results A total of 22 IIPP and S-CTG procedures in 20 patients were evaluated in the study. After a mean follow-up of 8.2 years (3.9–13.4) (T3), all implants remained osseointegrated (22/22 [100%]), with statistically insignificant mean midfacial gingival level change of −0.19 mm (−1.5 to 0.8). Statistically significant difference in midfacial gingival thickness (MFGT) was noted (2.5 mm [1.8–3.5 mm]) after a mean follow-up time (T2) of 2.3 years (1–8.6) when compared with MFGT at baseline (1.1 mm [0.6–1.3 mm]) (T1). Necrosis of S-CTG during initial healing phase was noted in 9% (2/22) of the sites. Conclusions Within the confines of this study, scarf-connective tissue graft at time of immediate implant placement and provisionalization can thicken the gingiva and maintain the gingival level at the critical soft tissue zone. Clinical Significance Managing the soft tissue zone is as important as that of the hard tissue zone for peri-implant esthetics. Connective tissue graft is one of the methods that can enhance the final esthetic outcomes. This retrospective study has demonstrated that Scarf-CTG technique is an effective treatment modality to maintain soft tissue stability. View on Web

Aktuelles Management des Basalzellkarzinoms

alexandrossfakianakis shared this article with you from Inoreader Aktuelles Management des Basalzellkarzinoms via Laryngo-Rhino-Otologie Laryngorhinootologie 2022; 101: 969-978 DOI: 10.1055/a-1861-7077 Ziel der Studie Der aktuelle Standard von Diagnostik und Therapie des Basalzellkarzinoms soll dargestellt werden. Hieraus sollen sinnvolle Vorgehensweisen für das klinische Management abgeleitet werden. Methodik Es erfolgte eine systematische Literaturrecherche in der Online-Datenbank PubMed. Die gesammelten Informationen wurden analysiert und bewertet. Aus den gewonnenen Erkenntnissen wurde ein Gesamtkonzept erstellt. Ergebnisse Das Basalzellkarzinom ist der häufigste Tumor des Menschen und die Inzidenz wird voraussichtlich künftig weiter zunehmen. Beim Management der Erkrankung wird eine eindimensionale Orientierung am klinischen bzw. histologischen Basalzellkarzinom-Subtyp der Heterogenität des Tumors nicht gerecht. Zunehmende Bedeutung gewinnt die primäre Durchführung einer Risikostratifizierung, die für die weiteren diagnostischen und therapeutischen Schritte maßgeblich ist. Goldstandard in der Behandlung bleibt weiterhin das operative Vorgehen, welches möglichst mittels mikrografisch kontrollierter Chirurgie erfolgen sollte. Daneben existieren weitere Therapieverfahren wie die Radiotherapie oder eine Reihe an topischen Therapieoptionen (photodynamische Therapie, Kryotherapie oder Applikation von 5-Fluoruracil bzw. Imiquimod), die in bestimmten Fällen zur Anwendung kommen können. Auch für fortgeschrittene oder metastasierte Basalzellkarzinome stehen mit den Hedgehog-Inhibi toren wirksame Medikamente zur Verfügung, für die inzwischen eine mehrjährige Anwendungserfahrung hinsichtlich Wirksamkeit und Umgang mit unerwünschten Ereignissen vorliegt. Mit dem PD-1-Inhibitor Cemiplimab steht seit Juni 2021 eine weitere therapeutische Option für nicht operable oder metastasierte Tumoren bereit. Schlussfolgerung Das Basalzellkarzinom wird in den kommenden Jahren weiter an Relevanz in der täglichen dermatologischen Praxis gewinnen. Eine strukturierte Herangehensweise zur Einschätzung der vorliegenden Risikokategorie des Tumors und die anschließende Festlegung des optimalen Therapieregimes sind von zentraler Bedeutung. Fortgeschrittene oder metastasierte Tumoren stellen keine aussichtslose Situation für den Patienten mehr dar. Durch adaptierte Dosierschemata kann ein nebenwirkungsbedingter Therapieabbruch unter langfristiger Hedgehog-Therapie vermieden werden. Ebenso kann das therapeutische Potenzial des PD-1-Inhibitors Cemiplimab unter dem von anderen Hautkrebsarten bekannten Nebenwirkungsprofil genutzt werden.

Zygomatic implant placement using a robot-assisted flapless protocol: proof of concept

alexandrossfakianakis shared this article with you from Inoreader Zygomatic implant placement using a robot-assisted flapless protocol: proof of concept via International Journal of Oral and Maxillofacial Surgery via MedWorm.com Robotic assistance can help in physically guiding the drilling trajectory during zygomatic implant positioning. A new robot-assisted strategy for a flapless zygomatic implant placement protocol is reported here. In this protocol, a preoperative computed tomography scan is used to plan the surgical path. After surface registration, the ROSA robot (Zimmer Biomet Robotics) guides several steps, which are performed with shared control. The surgeon performs the drilling and tapping, guided by the robotic arm, which is positioned according to the planned trajectory.

Incidental findings in cone beam computed tomography volumes: calcified head and neck atheromas detected during dental evaluation

alexandrossfakianakis shared this article with you from Inoreader Incidental findings in cone beam computed tomography volumes: calcified head and neck atheromas detected during dental evaluation via Journal of Prosthodontics Abstract Purpose Atheromas can be detected incidentally in routine dental cone beam computed tomography (CBCT) images. This study aims to assess prevalence and risk factors associated with these vascular lesions. Materials and Methods The maxillofacial CBCT's of 458 subjects were evaluated and divided into 4 groups based on the presence of calcified atheroma: subjects with no calcified atheroma, subjects with intracranial calcified atheroma (ICA), subjects with extracranial calcified atheroma (ECA), and subjects exhibiting combined lesions. Age, sex, medical conditions, family history, and size were documented. ANOVA followed by a multiple comparison test was used for data satisfying parametric test assumptions. Chi Square tests were used to assess categorical data. The Spearman's Rho test was used to assess the correlation between the incidence of calcified atheroma and subjects' medical condition. Results Of the 458 CBCTs evaluated, 29.90% presented with calcified atheroma. Calcified atheroma prevalence was significantly higher in older patients vs younger patients (p = 0.004) and in males compared to females (p = 0.004). Males were more likely to have the combination of intracranial and extracranial calcified atheroma while females were more likely to have intracranial calcified atheroma alone (p ≤ 0.040). Patients with calcified atheroma were significantly more likely to have a history of hyperlipidemia (p = 0.001), hypertension (p = 0.001), and myocardial infarction/coronary artery diseases (p = 0.001). Overall, patients exhibiting both intracranial and extracranial lesions were more likely to have cardiovascular risk factors (p = 0.001). Conclusion Incidentally detected calcified atheromas in CBCTs are common. Subjects with combined atheroma lesions are at higher risk for cardiovascular disease. The diagnosis of incidental calcified atheromas in CBCT's warrants early referral to medical specialists, especially if there is no medical history of existing cardiovascular disease.

Benign submandibular gland tumours: outcomes of gland-preserving excision by endoscopic or conventional approach

alexandrossfakianakis shared this article with you from Inoreader Benign submandibular gland tumours: outcomes of gland-preserving excision by endoscopic or conventional approach via International Journal of Oral and Maxillofacial Surgery via MedWorm.com Endoscope-assisted surgery is becoming a preferred technique in salivary gland surgery. However, this technique has not yet been applied in submandibular gland (SMG) preservation surgery. This retrospective study was performed to evaluate the outcomes of endoscope-assisted gland-preserving surgery through a hairline incision in patients with benign SMG tumours. The study included 38 patients with benign SMG tumours who underwent tumour excision with gland preservation: 19 who underwent local excision of the tumour through an endoscope-assisted hairline approach and 19 who received the conventional cervical approach.
