[Immunoglobulin E in nasal secretions]. / Immunglobulin E im Nasensekret.

Diagnosis of allergic disease is primarily verified by IgE blood serum analysis. Determination in nasal secretions is technically more difficult, particularly due to a low specimen volume and the method of sample collection. Nasal secretions are frequently collected by lavage, which allows qualitative diagnostics, whereas swabs with defined amounts of mucus enable quantitative analyses. In the case of negative skin and serum tests, detection of IgE in nasal mucus combined with nasal provocation testing aids differentiation between local allergic and nonallergic rhinitis.

[Allergen immunotherapy for rare allergens]. / Allergen-Immuntherapie gegen seltenere Allergene.

Among allergies to aeroallergens, approximately 20% are allotted to the so-called rare allergens. These include ash pollen, weed pollen, storage mites, molds, and animal allergens. The prevalences of allergies to these allergens are lower, but affected patients also suffer considerably from their "rare" allergy. Hence, these allergies should neither be overseen nor completely forgotten in daily practice. Especially mold, mite, and animal allergens often induce asthma, so that the significance of allergen-specific immunotherapy (AIT) should not be neglected in causal therapy. This work summarizes the current state of knowledge on the groups of rare aeroallergens in terms of characteristics, prevalences, and data on AIT. It is based on a systematic literature search performed in the MEDLINE (PubMed®) and Google Scholar databases. AIT preparations for rare allergens are classified as individual formulations and are not subject to the German Therapy Allergen Ordinance. Due to the low case numbers, the levels of evidence for these formulations are not as high as those for dust mites, grass, or birch pollen, but exhibit good efficacy in practical experience.

[Blast and explosion traumas-effects on the middle and inner ear based on the example of Bundeswehr foreign missions]. / Knall- und Explosionstraumata ­ Auswirkungen auf Mittel- und Innenohr am Beispiel von Auslandseinsätzen der Bundeswehr.

Despite all protective measures, blast and explosion traumas are a frequent pattern of injury in Bundeswehr missions abroad. Due to body protection measures, head injuries, particularly of the ears, are higher in number compared to injuries in other regions of the body. Perforations of the tympanic membrane are the most frequent lesions of the middle ear, acute sensorineural hearing loss is the most frequent lesion of the inner ear, often accompanied by tinnitus and dizziness. With a high spontaneous recovery rate, prompt specialist care for these injuries is provided according to medical standards comparable to those in the home country.

[Tolerance and acceptance of intratympanic injections]. / Toleranz und Akzeptanz der intratympanalen Injektion.

BACKGROUND: Intratympanic steroids are a therapeutic component in sudden hearing loss related to cochlear affection. Little has been published on patients' acceptance and tolerance to date. MATERIALS AND METHODS: A total of 84 patients were asked about health conditions and circumstances surrounding their intratympanic therapy. RESULTS: The patients comprised 38 women and 46 men, aged 57.2 years on average, who had mostly been referred by their ENT physician for second-line treatment. Reported were injection pain by 3.6%, discomfort by 22.6%, tolerability by 67.9%, and painlessness by 41.7% (more than one answer possible). Whereas 77.4% recommended intratympanic treatment, reasons for no recommendation were lack of efficacy and an unpleasant sensation. CONCLUSION: The majority of patients rated intratympanic therapy as bearable and recommendable. Close patient guidance seems to be an important part of the treatment.

Characteristics and Spontaneous Recovery of Tinnitus Related to Idiopathic Sudden Sensorineural Hearing Loss.

OBJECTIVE: To evaluate the characteristics and spontaneous recovery of tinnitus related to idiopathic sudden sensorineural hearing loss (ISSNHL). STUDY DESIGN: Retrospective analysis from two randomized placebo-controlled clinical trials for treatment of ISSNHL within 48 hours from onset (Study A), or of tinnitus related to ISSNHL within 3 months from onset (Study B). SETTING: Forty-eight European sites (academic tertiary referral centers, private ENT practices). PATIENTS: One hundred thirteen adult patients of which 65 with hearing loss ≥30 dB (Study A) and 48 with persistent acute tinnitus (Study B) at baseline. INTERVENTIONS: Intratympanic (i.t.) injection of placebo gel in single dose or in triple dose during 3 consecutive days. MAIN OUTCOME MEASURES: Frequency of tinnitus, subjective tinnitus loudness, rates of complete tinnitus remission, and complete hearing recovery during 3 months follow-up. RESULTS: In acute ISSNHL, tinnitus loudness decreased rapidly in cases of mild-moderate hearing loss, and tinnitus had completely resolved in two-thirds of patients after 3 months. Hearing recovery preceded tinnitus resolution. When associated with severe-profound hearing loss, tinnitus improved significantly less. Complete hearing recovery and full tinnitus remission were both about three times more frequent in mild-moderate hearing loss patients than in severe-profound cases. Improvement in tinnitus loudness over time can be approximated by a negative exponential function. CONCLUSIONS: Prognosis for ISSNHL-related tinnitus is relatively poor in case of severe-profound hearing loss and the longer it has persisted. Alleviation or management of tinnitus should be a key therapeutic objective especially in pronounced ISSNHL cases.
