They are usually organised in an orderly manner and densely compacted.Genetics is one of the causing factors of loose anagen syndrome. It has been studied that this hair condition is autosomal dominantly inherited. Diagnosis
Patients with loose anagen syndrome do not report the same hair abnormalities. Loose anagen syndrome is usually diagnosed after taking into consideration the physical examination, clinical history and a microscopic examination of the hairs of the patient. Some patients visit a dermatologist for diagnosis and to distinguish between loose anagen hair syndrome and other conditions that it can be misdiagnosed for.A pull test is performed in order to diagnose a patient with loose anagen hair syndrome as one of the characteristics of this hair condition is hair that is easily removed from the scalp. A group of around 40-60 hairs, that are attached to the scalp, is pulled in a clement manner. The patient will be diagnosed with loose anagen syndrome if great amounts of hair is detached from the head. If at least 50% of the hairs removed is at the anagen hair stage, the outcome of the pull test is positive. The detachment of only 4-6 hairs is considered a normal outcome, as approximately 10% of the hairs on the scalp are at the telogen stage. The removed loose anagen hairs are not fragile and are of normal tensile strength.In an electron microscope image of a loose anagen hair, deformities such as grooves, curls and ridges are visible in the hair shaft, which is made from keratin.
Aphonia is defined as the inability to produce voiced sound. Damage to the nerve may be the result of surgery (e.g., thyroidectomy) or a tumor.Aphonia means "no sound". In other words, a person with this disorder has lost their voice. Causes
Injuries are often the cause of aphonia. Minor injuries can affect the second and third dorsal area in such a manner that the lymph patches concerned with coordination become either atrophic or relatively nonfunctioning. Tracheotomy can also cause aphonia.Any injury or condition that prevents the vocal cords, the paired bands of muscle tissue positioned over the trachea, from coming together and vibrating will have the potential to make a person unable to speak. When a person prepares to speak, the vocal folds come together over the trachea and vibrate due to the airflow from the lungs. This mechanism produces the sound of the voice. If the vocal folds cannot meet together to vibrate, sound will not be produced. Aphonia can also be caused by and is often accompanied by fear. Psychogenic
Psychogenic aphonia is often seen in patients with underlying psychological problems. Laryngeal examination will usually show bowed vocal folds that fail to adduct to the midline during phonation. However, the vocal folds will adduct when the patient is asked to cough. Treatment should involve consultation and counseling with a speech pathologist and, if necessary, a psychologist.In this case, the patients history and the observed unilateral immobility rules out function aphonia.
