Dear Director, (Forwarded from the Director's mailbox)
I'm sorry to disturb you during your busy time.
My husband is in his thirties and was exposed to the chemical substance dimethylamine borane at work on February 1st.
Currently, he is experiencing cerebellar and central and peripheral neuropathy.
The company has consistently informed us that this substance is non-toxic, but after nearly six months of treatment, he still cannot move independently.
This case is the first of its kind in the country, and we are still undergoing treatment.
However, I have been unable to determine whether this condition is classified as a major refractory disease.
I would like to ask how we can define (major refractory disease) in medical terms, and what the criteria for defining significant injury are.
If your organization cannot assist me, could you please advise me on which organization I should contact? Thank you.

Dr. Ye Boshou reply Neurology
First, you can check if it is a rare disease on the website of the Rare Disease Foundation, which is -- http://www.tfrd.org.tw/cindex.php.
As for whether cerebellar lesions and central and peripheral neuropathies are caused by dimethylamine borane, you may seek consultation from Dr.
Lin Chieh-Liang, the Director of the Toxicology Department at Linkou Chang Gung Memorial Hospital, or the Toxicology Department at Taipei Veterans General Hospital.

More Info
I'm sorry to hear about your husband's situation. It sounds incredibly challenging, and I commend you for seeking clarity on such a complex issue.
In the medical field, "major intractable conditions" typically refer to diseases or injuries that are difficult to treat and do not respond well to standard medical interventions. These conditions often lead to significant impairment in daily functioning and quality of life. The definition can vary by jurisdiction and medical guidelines, but generally, it encompasses chronic illnesses that require extensive medical care, rehabilitation, or long-term management.
In your husband's case, exposure to a chemical substance like dimethylamine borane (DMAB) can lead to various health issues, including neurological damage, as you've described. The symptoms of central and peripheral nervous system damage can be profound and may include motor dysfunction, sensory loss, and cognitive impairments. The fact that your husband is experiencing significant challenges in mobility and autonomy suggests that his condition may indeed fall under the category of a major intractable condition, especially if it is resistant to conventional treatments.
To determine whether a condition is classified as "major" or "intractable," healthcare providers typically consider several factors:
1. Severity of Symptoms: The extent to which the condition affects daily life and functioning.
2. Response to Treatment: How well the condition responds to standard medical therapies. If treatments have been ineffective, this may indicate an intractable condition.
3. Duration of the Condition: Chronic conditions that persist over time without improvement are often classified as intractable.
4. Impact on Quality of Life: The degree to which the condition affects mental, emotional, and physical well-being.
In terms of defining "major injury," this often refers to injuries that result in significant impairment, disability, or require extensive medical intervention. This can include traumatic brain injuries, severe burns, spinal cord injuries, and other conditions that lead to long-term disability.
Given that your husband's case is unique and has not been documented widely, it may be beneficial to consult with specialists in occupational medicine, toxicology, or neurology. They can provide insights into the long-term effects of chemical exposure and help assess the severity of your husband's condition. Additionally, you may want to reach out to organizations that specialize in workplace safety and chemical exposure, as they may have resources or guidance on navigating the medical and legal aspects of such cases.
If you feel that your current medical team is not adequately addressing your concerns, consider seeking a second opinion from a different medical institution or specialist. It may also be helpful to connect with support groups or advocacy organizations focused on chemical exposure and occupational health, as they can provide valuable resources and support.
In summary, your husband's condition may indeed qualify as a major intractable condition due to the significant impact on his life and the challenges in treatment. Seeking specialized medical advice and support from relevant organizations will be crucial in navigating this difficult situation. I wish you and your husband the best in your ongoing treatment and recovery journey.
