Fechtner syndrome is a platelet defect. The cause is due to a mutation in the genetic material: Affected parents can pass the syndrome on to their children. What is Fechtner syndrome? Fechtner syndrome is an inherited disorder that the World Health Organization (WHO) classifies as a qualitative platelet defect (ICD-10, D69.1). The syndrome thus belongs … Fechtner Syndrome: Causes, Symptoms & Treatment
Electrostimulation involves contacting a motor nerve by means of applied voltage. This contacting causes an action potential to reach the muscle, causing it to contract. Therapeutic electrostimulation is used primarily for peripheral paralysis and is intended to prevent muscle atrophy. What is electrostimulation? Electrostimulation is therapeutic stimulation by an applied voltage source. Electrostimulative procedures are … Electrostimulation: Treatment, Effects & Risks
Beethoven was undoubtedly one of the very great European composers. He composed some of his most famous works when he could only communicate with “conversation books” due to his deafness. His progressive hearing loss began when he was only 26 years old. Today, most researchers believe that its cause was otosclerosis of the inner ear. … Otosclerosis: Gradual Hearing Loss
FG syndrome is an X-linked abnormality. Affected individuals suffer from defective vitamin D receptors and, as a result, multifaceted symptoms such as developmental delay, muscle weakness, strabismus, and sensorineural hearing loss. Treatment is symptomatic. What is FG syndrome? Chromosomal aberrations are also called chromosomal abnormalities. They are structural or numerical changes in chromosomes in an … FG Syndrome: Causes, Symptoms & Treatment
Magnetic resonance angiography serves as a diagnostic procedure for graphical imaging of blood vessels. Unlike conventional examination methods, the use of X-rays is not necessary. However, there are contraindications to the use of this procedure. What is magnetic resonance angiography? Magnetic resonance angiography, or MRA, is an imaging procedure used for diagnostic imaging of blood … Magnetic Resonance Angiography: Treatment, Effects & Risks

This surgically implanted hearing device offers patients with profound hearing loss, the chance to hear again. Something that was previously not possible with either analog or digital hearing aids. However, the prerequisite for this is a … Cochlear Implant: Treatment, Effects & Risks
Norrie syndrome is an early childhood, severe eye development disorder in boys. This is characterized by degenerative as well as proliferative changes in the neuroretina and can lead to blindness at a very early age. With few exceptions, Norrie syndrome occurs only in the male sex. An incidence of 1:100,000 is suspected. What is Norrie … Norrie Syndrome: Causes, Symptoms & Treatment
Usher syndrome is a gene mutation of various chromosomes that causes hearing-vision impairment of various degrees of severity. The most severe form, with congenital deafness and visual field loss, presents at age ten. While the partially progressive hearing impairment is treated with a hearing aid and later a chochlear implant, no therapeutic methods are yet … Usher Syndrome: Causes, Symptoms & Treatment
Electrocochleography (ECochG) is the name given to a method used in audiometry or ear, nose, and throat medicine to record electrical potentials produced by sensory cells (hair cells) in the cochlea in response to acoustic clicks or short tones at different pitches. Three different electropotentials are recorded, allowing detailed conclusions to be drawn about the … Electrocochleography: Treatment, Effects & Risks
