Obsolete Dominant Congenital Severe Sensorineural Deafness

The condition you're referring to appears to be an outdated term for a specific type of congenital hearing loss. Based on the search results, it's likely that this condition is related to a form of non-syndromic sensorineural hearing loss.

Characteristics:

• Severe-to-profound sensorineural hearing loss
• Typically affects males more severely than females
• Females may experience mild to moderate hearing loss

This condition is not explicitly mentioned in the search results, but it's possible that it was previously referred to as "obsolete dominant congenital severe sensorineural deafness." However, based on the information provided, it seems that this term is no longer used in modern medical literature.

Possible Causes:

• Genetic mutations or abnormalities
• Prenatal or postnatal disease or trauma

It's essential to note that the exact causes and characteristics of this condition are not explicitly stated in the search results. However, based on the information provided, it appears that this condition is a form of non-syndromic sensorineural hearing loss.

References:

• [10] - A form of non-syndromic sensorineural hearing loss.
• [15] - A form of deafness characterized by progressive, severe-to-profound sensorineural hearing loss in males. Females manifest mild to moderate hearing loss.

Common Signs and Symptoms

Individuals with congenital severe sensorineural deafness may experience a range of symptoms, including:

• Difficulty understanding speech: People with this condition often struggle to comprehend spoken language, particularly in noisy environments [14].
• Muffled or distorted sounds: Sounds may seem dull or unclear, making it challenging to perceive high-pitched tones or distinguish between different frequencies [15].
• Constantly asking others to repeat themselves: Individuals with severe sensorineural deafness may frequently request that others rephrase their statements due to difficulty understanding spoken language [14].

Additional Symptoms

Some people with congenital severe sensorineural deafness may also experience:

• Ringing in the ears (tinnitus): A persistent ringing or buzzing sound in the ears, which can be a symptom of various ear-related conditions.
• Dizziness or lightheadedness (vertigo): In some cases, individuals with this condition may feel unsteady or experience vertigo due to difficulties with balance and equilibrium.

Important Considerations

It's essential to note that congenital severe sensorineural deafness is a permanent condition, and symptoms can vary in severity from person to person. If you suspect someone has this condition, it's crucial to consult with an ear specialist for proper diagnosis and guidance.

[14] Congenital hearing loss can be defined as hearing loss present at birth and is due to an impairment in the conduction and/or conversion of sound into electrical nerve impulses. [15] Hereditary hearing loss accounts for almost 50% of all congenital sensorineural hearing loss cases.

Based on the provided context, it appears that you are looking for diagnostic tests related to congenital severe sensorineural hearing loss.

According to search result [2], diagnostic imaging typically consists of computed tomography (CT) of the temporal bone and magnetic resonance imaging (MRI) of the brain and internal auditory canal. These tests can help identify any structural abnormalities or lesions that may be contributing to the hearing loss.

Additionally, as mentioned in search result [6], results of the following were reviewed: magnetic resonance imaging, computed tomography, renal ultrasound, electrocardiography, fluorescent treponemal antibody absorption test (FTA-ABS), and other tests. These tests can help rule out any underlying conditions that may be causing the hearing loss.

It's also worth noting that next-generation sequencing (NGS)-based testing can now provide most analyzed USH patients with a molecular diagnosis, based on mutations in 11 genes [7]. This test can help identify the genetic cause of the hearing loss and guide further management.

Furthermore, as stated in search result [10], evaluation of congenital hearing loss starts with newborn hearing screenings with auditory brainstem evoked responses (ABRs) and includes a thorough history and physical exam, diagnostic imaging, electrocardiography, genetic testing, and consultation, and ophthalmological exam. These tests can help identify the underlying cause of the hearing loss and guide further management.

In terms of specific diagnostic tests for obsolete dominant congenital severe sensorineural deafness, it's worth noting that this condition is often associated with mutations in the USH2A gene [14]. However, the exact diagnostic tests used to diagnose this condition may vary depending on individual circumstances.

Based on the search results, it appears that there are limited treatment options available for autosomal dominant congenital severe sensorineural deafness.

According to search result [10], the majority of genetic hearing loss is nonsyndromic, and of nonsyndromic hearing loss, the majority is autosomal recessive (80%), followed by autosomal dominant (15%) and X-linked (1%). However, there is no specific mention of drug treatment for autosomal dominant congenital severe sensorineural deafness.

Search result [5] mentions a study on the treatment of acute hearing loss patients with acetyl salicylate and meclofenoxate, but it does not specifically address autosomal dominant congenital severe sensorineural deafness.

It's worth noting that search result [8] discusses gene therapeutic and optogenetic research relevant to the restoration of hearing and vision, but it does not provide information on drug treatment for autosomal dominant congenital severe sensorineural deafness.

However, search result [9] mentions that there are no FDA-approved drugs for treating sensorineural hearing loss, which includes autosomal dominant congenital severe sensorineural deafness.

Therefore, based on the available information, it appears that there is currently no established drug treatment for autosomal dominant congenital severe sensorineural deafness. However, research in gene therapy and optogenetics may hold promise for future treatments.

• There are limited treatment options available for autosomal dominant congenital severe sensorineural deafness [10].
• Acetyl salicylate and meclofenoxate have been used to treat acute hearing loss, but not specifically for autosomal dominant congenital severe sensorineural deafness [5].
• Gene therapeutic and optogenetic research may hold promise for future treatments, but no established drug treatment is currently available [8][9].

A very specific and technical question!

Based on the context provided, it seems that you're looking for a differential diagnosis for a rare form of congenital severe sensorineural deafness with an autosomal dominant inheritance pattern.

From the text, I found a few examples of genes associated with autosomal dominant forms of hearing loss:

1. COL11A2 (DFNA13) - a missense mutation in this gene is associated with a form of dominant hearing loss.
2. WFS1 - mutations in this gene are the most common cause of dominant low-frequency sensorineural hearing loss.

However, I couldn't find any specific information on "obsolete" forms of dominant congenital severe sensorineural deafness. It's possible that you may be thinking of a different condition or gene.

If you could provide more context or clarify what you mean by "obsolete", I'd be happy to try and help further!
