Alport syndrome (also called progressive hereditary nephritis) – genetic disorder with both autosomal dominant and autosomal recessive inheritance with malformed collagen fibers that can lead to nephritis (kidney inflammation) with progressive renal failure (kidney weakness), sensorineural hearing loss, and various eye diseases such as a cataract (cataract) Alström … Noise Trauma: Or something else? Differential Diagnosis
The following are the most important diseases or complications that may be contributed to by noise trauma: Ears – mastoid process (H60-H95). Permanent hearing damage Tinnitus (ringing in the ears)
Acomprehensive clinical examination is the basis for selecting further diagnostic steps: General physical examination – including blood pressure, pulse, body weight,height, etc. ENT medical examination including medical device diagnostics (e.g. sound threshold audiometry).
2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification. Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate). Smear for bacteriological / mycological examination.
Therapy target Improvement of symptomatology Therapy recommendations For noise trauma, the following are used: Infusion therapy to improve the fluidity of the blood or blood flow-enhancing therapy: low-molecular-weight dextrans, pentoxifylline (vasodilator/drugs that dilate blood vessels) (there is no proven evidence of efficacy). Prednisolone equivalent (glucocorticoids): prednisolone equivalent, 250 mg for 3 days. Hyperbaric oxygenation (HBO; … Noise Trauma: Drug Therapy
Audiometric testing procedures are used to diagnose hearing disorders.These tests include: Tone threshold audiometry – tones of different frequencies with different volumes are played and the volume is determined at which the patient can just hear the tone of the respective frequency; furthermore, sound conduction is performed by air and bone conduction, this allows a … Noise Trauma: Diagnostic Tests
1st order In blast trauma with rupture of the eardrum (tympanic membrane) – surgical rehabilitation may be required depending on the findings.

Pathogenesis (development of disease) In noise trauma, various external influences such as a bang or explosion cause damage to the hair cells of the organ of Corti (organ of Corti; term for the interface between acoustic mechanical vibrations and nerve signals in the cochlea of the inner ear). When the adaptive capacity of the ear … Noise Trauma: Causes
General measures Review of permanent medication due topossible effect on existing disease. Avoidance of environmental stress Explosion trauma Noise – so there is a risk of noise-induced hearing loss at constant or year-long sound levels of 85 dB(A); even short-term strong noise such as loud disco music (110 dB) should be avoided; among the recognized … Noise Trauma: Therapy
