Novel, standardized sample collection from the brain-nose interface.

Background: Diagnostics for neurodegenerative diseases lack non-invasive approaches suitable for early-stage biochemical screening and routine examination of neuropathology. Biomarkers of neurodegenerative diseases pass through the brain-nose interface (BNI) and accumulate in nasal secretion. Sample collection from the brain-nose interface presents a compelling prospect as basis for a non-invasive molecular diagnosis of neuropathologies.

Bilateral Keloid Formation after Otoplasty in the Presence of Prolonged Mask Wearing.

Prominent ears are the most frequently observed congenital deformity of the head and neck. Various techniques have been proposed for their aesthetic correction. Typically, surgical treatment for protruding ears involves a combination of suture, cutting, and scoring techniques.

Clinical Relevance of Profilin Sensitization Concerning Oral Allergy Syndrome in Birch Pollen Sensitized Patients.

Purpose: Many plant food allergens contain homologs to the major birch allergen Bet v 1; therefore, the majority of patients with birch pollen allergy suffer from oral allergy syndrome. We studied the relevance of sensitization of Bet v 1 and co-sensitization with profilin concerning the clinical manifestations of an oral allergy syndrome.

Patients And Methods: A total of 1119 patients with a positive skin prick test to birch and diagnostic for specific IgE to the allergen components Bet v 1 and profilin were analyzed retrospectively regarding complaints in the upper and lower airways, with demographic data as well as oral and gastrointestinal allergy symptoms.

Relevance of Major Allergens in Weed Pollen Allergy.

Introduction: Weed pollen allergy is an important and in prevalence increasing cause of pollinosis in Europe and across the world. In this study we focus on the value of common diagnostic tools for detection of a sensitization to mugwort and English plantain, especially with regard to the clinical relevance of the sensitization.

Methods: Eighty weed pollen sensitized patients (41 to mugwort and 39 to English plantain) were assessed retrospectively regarding their clinical anamnesis, in-vivo tests (skin prick test [SPT] and allergen specific provocation) and in-vitro tests (immunoglobulin E [IgE] reactivity to purified natural allergen extract and specific allergen components in serum).

AERD Associated Nasal Polyposis: Efficacy of Postoperative Antileukotriene Therapy in Comparison with Aspirin Desensitization. A Retrospective Study.

Introduction: AERD (aspirin-exacerbated respiratory disease) is a severe form of an inflammatory disease of the upper airway system. Therapy remains challenging due to a complex underlying pathophysiology.

Objective: To evaluate the efficacy of postoperative antileukotriene therapy concerning recurrence of nasal polyposis in patients with AERD and to compare it with AD (aspirin desensitization) over time.

The nasal valve: new insights on the static and dynamic NV with MR-imaging.

Purpose: We assessed the static nasal valve angle with MR imaging in healthy subjects and evaluated the complex mechanism of nasal valve dynamics during physiologic and forced inspiration.

Methods: In 17 healthy subjects, measurements of the static nasal valve angle were conducted on MR scans, using a TSE Axial T2-weighted sequence and a 3 mm slice thickness. The dynamic changes of nasal valve movement were detected using MR Cine-imaging techniques.

The time course of nasal cytokine secretion in patients with aspirin-exacerbated respiratory disease (AERD) undergoing aspirin desensitization: preliminary data.

Purpose: Aspirin-exacerbated respiratory disease (AERD) is a severe form of chronic rhinosinusitis with nasal polyps (CRSwNP) accompanied by asthma and an aspirin intolerance. The underlying pathomechanism of AERD still remains unclear, recent data suggest a complex inflammatory imbalance. In the present study, we investigated the cytokine patterns in AERD, CRSwNP and healthy control patients.

A 2-Year Follow-up Study of an Absorbable Implant to Treat Nasal Valve Collapse.

The safety and effectiveness of an absorbable implant for lateral cartilage support have been recently demonstrated in subjects with nasal valve collapse (NVC) at 12 months postprocedure. This follow-up study aimed to assess whether the safety and effectiveness of the implant persist in these patients for 24 months after the procedure. Thirty subjects with Nasal Obstruction Symptom Evaluation (NOSE) score ≥ 55 and isolated NVC were treated; 14 cases were performed in an operating suite under general anesthesia and 16 cases were performed in a clinic-based setting under local anesthesia.

The Clinical Impact of Bet v 6 in Birch Pollen-Sensitized Patients.

Background: Bet v 6, a minor birch pollen allergen, is commercially available for allergen-specific IgE antibody testing. However, there is hardly any literature on the clinical impact of Bet v 6. The aim of the present study was to analyze if testing specific IgE against Bet v 6 can add valuable benefit to the standard diagnostics of birch pollen-sensitized patients, especially in patients with unknown sensitization-eliciting allergens.

Absorbable Implant to Treat Nasal Valve Collapse.

 To evaluate the safety and effectiveness of an absorbable implant for lateral cartilage support in subjects with nasal valve collapse (NVC) with 12 months follow-up.  Thirty subjects with Nasal Obstruction Symptom Evaluation (NOSE) score ≥ 55 and isolated NVC were treated; 14 cases were performed in an operating suite under general anesthesia and 16 cases were performed in a clinic-based setting under local anesthesia. The implant, a polylactic acid copolymer, was placed with a delivery tool within the nasal wall to provide lateral cartilage support.

Usefulness of component resolved analysis of cat allergy in routine clinical practice.

Background: Cat allergy is of great importance, and its prevalence is increasing worldwide. Cat allergens and house dust mite allergens represent the major indoor allergens; however, they are ubiquitous. Cat sensitization and allergy are known risk factors for rhinitis, bronchial hyperreactivity and asthma.

Prevalence of Headache in Cochlear Implant Patients: A Cross-sectional Study.

Introduction: In Internet forums and other social media many reports regarding chronic headaches after cochlear implantation can be found. Although quite rare, there are also some reports in the literature. However, little is known regarding the true prevalence of headaches in persons who have undergone cochlear implant surgery.

Cytokine patterns in nasal secretion of non-atopic patients distinguish between chronic rhinosinusitis with or without nasal polys.

Background: Being one of the most common nasal diseases, chronic rhinosinusitis (CRS) is subdivided into CRS with nasal polyps (NP) and CRS without nasal polyps (CRSsNP). CRSsNP presents itself with a TH1 milieu and neutrophil infiltration, while NP is characterised by a mixed TH1/TH2 profile and an influx of predominantly eosinophils, plasma cells and mast cells. For the purpose of discovering disease-specific cytokine profiles, the present study compares levels of mediators and cytokines in nasal secretions between CRSsNP, NP, and healthy controls.

Clinical Relevance of IgE to Profilin and/or Polcalcin in Pollen-Sensitized Patients.

Background: Component-resolved diagnostics is gaining importance in allergy diagnostics. Allergen extracts contain components with different rates of prevalence and clinical relevance, which can be subdivided at molecular level into major and minor allergens. Clinical complaints are usually triggered by major allergens, while the role of sensitization to the panallergens profilin and polcalcin still remains unclear.

Milestones in the History of Ear Reconstruction.

The reconstruction of ear deformities has been challenging plastic surgeons since centuries. However, it is only in the 19th century that reports on partial and total ear reconstruction start increasing. In the quest for an aesthetically pleasing and natural-looking result, surgeons worked on the perfect framework and skin coverage.

Cytokine profiles in nasal fluid of patients with seasonal or persistent allergic rhinitis.

Background: New therapeutic approaches with biologic agents such as anti-cytokine antibodies are currently on trial for the treatment of asthma, rhinosinusitis or allergic diseases necessitating patient selection by biomarkers. Allergic rhinitis (AR), affecting about 20 % of the Canadian population, is an inflammatory disease characterised by a disequilibrium of T-lymphocytes and tissue eosinophilia. Aim of the present study was to describe distinct cytokine patterns in nasal secretion between seasonal and perennial AR (SAR/PAR), and healthy controls by comparing cytokines regulating T-cells or stimulating inflammatory cells, and chemokines.
