Hi,
I came across this website friday 29th June 2012. I have been researching for around two years now in regards to what could be the cause of my sons sudden pain in his cheek and forehead. My son is called riley, around the age of two riley started with funny episodes where he would get facial pain in his cheek and head. This made him sick on several occasions, he would also sleep for sometime after the episodes. 

Riley has been under his paediatrician since they started who thought possible seizures was the cause. Riley has had EEG, ECH metabolic blood tests and urine samples. All were reported as satisfactory. Riley's last appointment was on Monday 11th June 2012 which his paediatrician left us with no answers and asked us just to keep my son off his wii and see how he goes. He was also discharged, so we was still left in the dark. On Friday 29th of June riley woke crying in pain around 11pm we gave him paracetamol. He cried for around 30-40 minutes, in pain holding his cheek.

Asked me "mum why does this keep happening to me" his voice desperate for answers. Riley was 5 in January, this has gone on for some time now and we are still left with no answers. Having to explain to my 5 year old son that I don't know is just not the answer. I sat frantically trying to research Riley's symptoms on the Friday night. I came across this site where I found a story called Emily's story. Emily's story sounds exactly the same as Riley's.

Riley's and Emily's symptoms are very much the same. I have now written to my sons paediatrician with details so hopefully they can look into TN, I would appreciate any information or advice you can give me. I'm desperate for some answers as I can't stand seeing my son like this any longer.

Thank you for taking your time to read my email.

Shelly Forster:

 

The Purpose of Pain

 

 

Shelly with her family

By Hanna Smith

It was Shelly Forster’s most burning question: What is my purpose?

Fighting through reconciling the logistics of her new life diagnosed with chronic pain, rock bottom became her home in 2008 – and it left her with a choice.

2008 is the year Forster underwent two brain surgeries and was diagnosed with three chronic pain disorders – oral mandibular dystonia, trigeminal neuralgia and tardive dyskinesia – all of which transformed her from an independent woman working in nuclear engineering to a homebound patient fighting for her life.

“Pain is the great debilitator,” Forster said. “Chronic pain is a different animal all together, but takes on a new, terrifying element when it’s neurological.”

A congenital tumor inside Forster’s cerebellum was the root of her startling symptoms – muscular contractions in her neck, loss of voluntary control of her jaw and tongue, and splitting migraines.

For some time prior, Forster attributed the consistent headache and preliminary symptoms to stress at her job as a document control specialist for a nuclear engineering company. Such a job often required 70-hour weeks with round-the-clock hours. Forster assumed her symptoms to be somewhat normal considering the abnormal circumstances.

However, when the pain worsened and ultra-abnormal symptoms arose, she sought medical attention. Forster walked out of the doctor’s office with an emergency brain surgery scheduled the next day to remove the tumor inside around her cerebellum – the brain’s motor control center, which explained the involuntary movements in the cervical region of her head.

Dystonia impacts approximately 250,000 people in the United States, according to the American Association of Neurological Surgeons. Despite it being the third most common movement disorder, it is widely un-recognized by the public.

Forster underwent a surgery which removed the tumor. She was able to go home and began the recovery process. However, during a follow-up appointment, an additional MRI revealed there was a secondary tumor – this time woven within her cerebellum.

Forster for the second time was scheduled for emergency surgery, during which the surgeon filleted her cerebellum to remove as much of the tumor as possible. By the time the surgery was finished, however, 20 percent of the tumor was untouchable and too entangled in nerves. This portion still remains in Forster’s cerebellum to this day.

Prior to the operations, Forster says she understood her painful symptoms were in direct correlation with the tumors. Thus, following the surgical removal, she also assumed, based on medical opinion, that those symptoms would disappear.

 

Reality, however, did not meet those expectations.

Because of the neural damage coupled with the manipulation of the cerebellum during the procedures, Forster was left with permanent damage that resulted in her ongoing diagnosis of TN, dystonia, and tardive dyskinesia. It took visits to approximately four doctors before she was properly diagnosed.

THE FIRST THREE YEARS

With fluctuating medical treatments as doctors attempted to find a perfect medicinal cocktail to treat her pain – all the while attempting to acclimate to these new doses – Forster remembers the first three years of her illness as a fog.

During that time, she kept journals. Always a writer since childhood, putting her thoughts – no matter how jumbled – on paper helped her express and sort the emotions jostling through her mind.

“I took notes. I wrote things down about how I felt and what I was thinking – my faith and family and the roles both played,” she said. “I wrote down the good and the bad.”

Many days, Forster’s pain levels were off the charts and she was unable to function. It was during this time that she asked the pivotal question which determined the rest of her life: What’s my purpose?

Finding a purpose in the pain, she said, was the key for her survival by developing psychological motivation which would bolster her physical perseverance.

A wife, mother of three and now grandmother of three, Forster says she didn’t have to look far. Additionally, she began to recognize the unique position her illnesses put her in. Forster said this made her feel responsible for sharing her story with others – with the end goal of letting people with chronic pain know they’re not alone.

Fighting for her health meant fighting for her family and for others in similar situations.

Forster clearly found her purpose.

“It’s easy to accept your situation and move on,” she said. “But when you start paying attention to the battle and educate yourself, you’ll increase your quality of life.”

THE OTHER SIDE

Amid the turmoil of the first three years, a precedent was set in many facets of Forster’s life – experiences which developed the dynamics of what would become her new normal.

“I was able to discover trends,” she said. “I put a magnifying glass over the truth.”

Some relationships were lost. And although those years are met with what she says are some regrets, she knows the Shelly Forster of that time was often not reflective of her true character. During those times, pain sometimes spoke louder.

“It’s OK to walk away from relationships, no matter who they are, if that person cannot support them during their darkest moments,” she said. “We need to be relieved from that accountability.”

On the other hand, however, she says she knows the lost relationships proved who would stand by her side through the worst time of her life – and who couldn’t or wouldn’t. From that point, she established her core team of reliable people who became her baseline for support.

“When pain begins to define relationships, you are beginning to find out what other people are made of,” she said. “It’s the recognition that, because pain is part of my everyday life, those people are the ones that I need to walk away from for my benefit.”

Forster also established a core medical team. Because of the rarity of her disorders, she was referred to medical specialists, many of whom were considered cutting edge in their fields. But, being cutting edge, she discovered, did not equally entail compassion and willingness to advocate for patients. Through this realization, Forster learned to advocate for herself – even if it meant cutting off ties with doctors whom did not have her best interest in mind or were unwilling to help in her fight for her life.

This journey ultimately landed her at the Rochester, Minnesota-based Mayo Clinic, where she began undergoing botulinum toxin injections. According to The Dystonia Society, BTX treatment injects Botox directly into the targeted muscle which is impacted by dystonic activity. Although botulinum toxin is toxic in purified and controlled doses, it can help to relax muscular activity.

At the Mayo Clinic, Forster was treated by now-retired Dr. Joseph Matsumoto, who every three months typically administered 12 injections into her cervical muscles. The needles, approximately 30-gauge, are connected to a monitoring machine which judges the muscular-contraction activity at the time of injection with an auditory response. Always, the machine is buzzing at high volume when the needles are inserted. Forster’s husband Tom said sometimes he can see the needle bend slightly as it attempts to pierce the muscle.

Her daily companion for treatment is the pill box – containing pills assisting with pain relief, muscle relaxers, antispasmodics, blood pressure for hypertension linked to pain, and anti anxiety. Creating this fine-tuned cocktail took 10 years, and Forster said it still changes periodically as new medications are produced. It’s all trial and error.

 

NEW NORMAL

For all the absurdities and abnormalities in her life, Forster recognized trends and patterns – details that made her world a better environment. She learned her body’s unique responses to treatments or the lack thereof. Mitigating stress and being selective regarding which social interactions were most pertinent allowed her to venture from home without facing devastating impacts.

“What I’m going through is overwhelming enough,” Forster said. “I’m just getting through this moment. And not just get through. I’m trying to live this moment. Chronic pain patients need to know there’s life.”

Moving forward in this mindset, Forster said she’ll often plan ahead when she knows there is an important event she wants to attend – such as her grandson’s birthday party. In the days leading up to the event, Forster will rest more frequently and ensure she’s medicated properly.

Forster continued to write. This time, however, it was tracking her knowledge, medical progression, and jotting down pieces of inspiration that ignited fire in her fight for life. From psychology to medical management, Forster began to formulate her new normal.

At the same time, her purpose of pain began to grow arms and legs – and a plan came into focus. Forster fell back on her writing abilities, ultimately beginning work on a medical biography to share her story and gained knowledge to assist others who need direction in learning how to find a new normal after a chronic pain diagnosis.

Looking back, Forster recalls the many dark days when she considered what her purpose was. But, today, she is grateful to be alive with her purpose living and growing around her in the form of family and advocacy for others.

“The dark days behind me taught that the dark days to come are survivable,” she said. “Every time you have to apply that strength, it means you’ve got it in you for the next time.”

Why Is Research

Important

Have you ever gotten up in the morning and been very excited about the prospects for the day?   You’ve have a new friend to meet or you’re going on a trip to an area you’ve never been or you’re going to revisit and reconnect with an old friend.  All these are exciting because something new is going to happen, something different, and you’re going to come away with new feelings and different perspectives.  Research is exactly like that.  The origin of the word from the old French says exactly that, that you’re going to look very intensively for something( Old Fr. recherche). 

Researchers get involved because they get excited about something that’s not known or something that’s not completely explained and they dedicate literally years of their lives, days of their weeks, and hours of their days trying to find these bits of information.  What’s even more fun for a researcher though, is finding other pieces of information, little sidebars as it were, that were not known before.  These sidebars are important ,not as a detour, but as an increasing amount of knowledge that’s adding to the general fund of things we know and things we can work with in our lives.  People talk about the fact that research is important in medicine because it makes it possible for some cures or some improved treatments and that’s certainly the case with the Facial Pain Research Foundation. It means much more than that because if we can find how something works, whether it be something in our own body or something outside our body in the atmosphere or something outside ourselves beyond the planet, we’re going to be that much richer for the experience.  We also know that research allows us to understand several sides of a given question. 

For years the world was flat and everyone believed you could sail off the end.  Researchers and explorers showed that based on their calculations from the time of Galileo and da Vinci to the times of Columbus and other explorers that that’s not true. It is a circle of land, water, and people. The world exists as a collected community.  Research can provide truth and put paid to certain mistruths or errors in knowledge that may hold us back and may stop us from going in the right directions. It’s a way to support day to day life and to support fundamental truth. 

Research offers us all an opportunity to pursue more each day when  we get up and when a researcher puts together a hypothesis and begins the steps to take that hypothesis piece by piece and develop it into a theory and the theory translates into practice, every single one of us will benefit. 

Research is important because we go back and search again through what’s happened and look again at what has already been written down and done and with a very critical eye and an unparalleled intensity, we ask what more can we do, what more can we accomplish, what more can we learn.

How and why did you become Involved In the “World” Of Scientific Research?

TG: I’ve loved biology from as far back as I can remember. The real catalyst was when I was in my junior year in college. I didn’t know what I was going to do. I was thinking about going back and teaching at a boarding school for a while before I figured out what I was going to do with my life. But I was a biology major at Amherst College and I took a course with a professor named Richard Goldsby, a wonderful teacher, who was basically teaching a graduate level course to undergraduates. We had to write a term paper, a research-hypothesis type paper, the first time I’d had to do that in college, and the response back was that this was one of the best papers he’d read in many years, undergraduate or graduate. Please come talk to me. I think you might like to do research. 

Your laboratory conducts disease oriented research with specific, but not exclusive focus on neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. How did you get involved in developing a research project to find a cure for Trigeminal Neuralgia and related neuropathic pain?How did the development of this research project come about, and what motivated you to take on the leadership role?

TG: I make no claims about being a facial pain or trigeminal neuralgia expert. I’m just thinking opportunistically about how we can make a difference. When I came to the University of Florida, I was the founding director of the Center for Translational Research in Neurodegenerative Disease. The chair of the department of neurology at that time had hired somebody named Dr. Andy Ahn. Andy worked on headache and pain, and the director needed a place for him. I had some space at that time, so Andy was a scientific neighbor, and we would have discussions.

The University of Florida is one of the hotbeds in the world in terms of a gene therapy approach based on adeno-associated viral vectors – we call it AAV for short. A former dean actually discovered this virus. One of our senior faculty members participated in creating the first gene therapy vectors around it. My lab had already been using AAV vectors, but we doubled or tripled down when we came to the University of Florida. AAV has a naturally affinity to get into neurons.

So Andy sort of triggered this, but my bandwidth was stretched at that point – it’s still stretched. I kept on tweaking Andy to go down this road. Andy left academics, and at some point I said I should do this.

We felt it could be something that could be rapidly translatable. Finding a cure for trigeminal neuralgia is a huge unmet medical need, but it’s an orphan disease that doesn’t affect enough people to attract a huge amount of attention.

There’s a chance for harm if we get into humans, but the nice thing about working with trigeminal neuralgia is we can at least start our initial studies in humans in people whose next option is surgical ablation of the trigeminal nerve. That means that there’s an out if we actually happen to make people worse. When we do these kinds of trailblazing experiments or envision them in humans, we need to make sure that if something could go wrong we have a way out.

Now we’ll begin the animal phase of study – testing in animals. And I know how much this research can really affect people’s lives. It may not work, but we have everything in place to test it. So let’s try.  

If Gene Therapy isn’t new, why do you believe that it can work to block pain signaling in the nerve? 

TG: It really comes down to technical details. People have used the wrong vectors before that had their own liabilities. I honestly just don’t think people have thought that much about this approach.

Last year, gene therapy had its first really radical major success outside of the eye, which was with children who had a disease called spinal muscular atrophy (SMA). They were treated systemically with a AAV vector – a different flavor of the same thing. These kids basically get spinal motor neuron degeneration when they’re young, by the time they’re two years old, typically, they die. Fifteen children were treated with huge amounts of virus, and reports last October showed that every one of these kids was alive at two years of age. And those with high-dose vectors, many of them were almost asymptomatic. At that age the expected survival rate would have been eight percent. So there are some children walking and living normal lives after gene therapy who otherwise would be most likely dead.

So I think that was a turning point in the field, to say this, AAV-based gene therapies, really will have its place in modern medicine. And that study in SMA was much more heroic and much more challenging than what we envision. So I think the time’s right. We know we can deliver the gene to the nerve. So now it’s just finding the right gene that will dampen pain signaling in that set of neurons, hopefully without doing harm.

Supposing your theory and project is proven successful. What implications or lessons wil this work provide for other researchers?

TG: I think it would say that perhaps the gloves come off on gene therapies for many disorders, especially things that are targeting nerve cell dysfunction. 

Because of the Hippocratic Oath – physician, do no harm – we need an out, so we wouldn’t want to go and do this on intractable sciatic nerve pain. Because what happens if you make them worse – you can’t cut their sciatic nerve without serious implications.

But I think success could open up the door to many different approaches targeting pain. And given the current opioid epidemic, driven from people at least initially taking these medications to treat chronic pain – (whether that’s right or wrong or medically appropriate is another question) – I think this viral approach enables us to deliver the medicine or treatment precisely to the cells or organ or nerve and hopefully avoid the systemic side effects that would come from taking a pill or an antibody or other approaches.

Genetics Study 

Finds Genes That Cause Trigeminal Neuralgia

 Introduction by Michael Pasternak

 

In 2012 The Facial Pain Research Foundation approved a research study to find the genes responsible for trigeminal neuralgia. 

While each of our Foundation’s scientific projects are valuable, the one that has been the most awesome and challenging for me has been the Genetics/DNA project. Dr. Doug Anderson (FPRF Director of Research) and I have had to communicate with scientists from four different countries (including Joanna Zakrzewska in London) and Collection Centers in 9 different cities in three countries! Doug has spent months on this project “everyday”! He has also had to communicate with additional scientists interested in our efforts and has done this while still overseeing the creation and development and evaluation of all of our Foundation’s other projects! How did we and he get so lucky? 

While Doug has overseen and worked through the science some of our other Volunteers have been involved in working with the DNA Collection Centers, working through intellectual property problems, legal questions, raising the funds to pay for all of this, communicating to patients to give their DNA, creating PR pieces for the public to participate, keeping track of collection numbers, certifying completion of collections and data sent to OHSU and Rutgers, and making payments to the Collection Centers for their efforts. This project has been an enormous accomplishment. No Volunteer Foundation or organization has ever done this before! All completed while we grew our outstanding scientific project numbers to six and linked with two venture capital funded research projects. 

The FPRF has spent over $650,000 of funds raised by our Volunteers and donors on this project. The FPRF Trustees have committed another $325,000 to complete the project in the next year. 

So, now we have a team of scientists who have worked hard using their unique skills and understandings and have presented a report to our Trustees and asked to go forward to replicate the study during the next year to prove that what they have found are really the genes that will lead us to finding the cures. The Cilker Genetics/DNA Research Report has arrived. It is remarkable. We are extremely thankful to Drs. Devor, Burchiel, Seltzer, Diehl and Anderson for all of their voluntary efforts to create these findings. We are also truly thankful for Our Trustees and all of our Volunteers who helped raise the necessary funds to complete the tasks. This is an exciting time for all of us committed to ending the pain for all TN and related neuropathic sufferers. 

The Following is a Non-Technical Summary Report…The detailed full Scientific Report has been presented to the Foundation Trustees and contains confidential information. It will be confidential until the replication of findings has been completed. Following the report is an article by Dr. Scott Diehl for general distribution.

Findings and Future Plans – Non-Technical Summary

The main goal of our study is to find genes that cause “Classical” Trigeminal Neuralgia Type 1 (TN1). This information will help clinician-scientists find cures that relieve patients’ severe chronic pain or prevent it from developing. Thus far, we’ve searched the genetic material (DNA) of TN1 patients at over a million places where people are known to differ from one another in their DNA letters (A, T, G or C). On average, any two people have about five million DNA differences between them. Most differences have no effect on health, but some cause or predispose to disease. Our challenge is to find the “needles in a haystack” that cause TN1, hidden among the millions of differences with no relation to TN1. We do this by comparing DNA of TN1 patients (cases) with that of people who do not have TN1 (controls).

 Our initial search focused on 348 Caucasian TN1 patients, a modest sample size for human genetic studies today. Nevertheless, we are delighted to report discovery of several regions in the human genome with promising evidence they may harbor genes causing TN1. Some regions include only one gene, but there are 17 genes in the genome location with the strongest statistical support, including 3 with biological functions involving nerve degeneration, excitability of neurons or responses to nerve injury. These genes are strong suspects, but to determine which genes actually cause TN1we need a combination of: a) more genetic data of the kind we have already been gathering, and b) information from a complementary approach that uses high speed DNA sequencing. This further research is absolutely necessary before our initial discoveries are ready for testing in animals or translation to the clinic. 

First, we must be absolutely certain our TN1 patients and controls do not happen to be very different by chance alone, but that the DNA differences occur because mutations hidden in the regions actually cause TN1. To do this, we will repeat our experiment a second time and see if we get the same results. We will analyze variation across the human genome for a new set of TN1 patients and controls using the most advanced genomic assays now available, more than doubling our sample size. If the same genome regions are again different in TN1 patients compared to controls (like lightning striking in the same place twice), this replication will confirm that TN1 disease-causing genes are indeed located there. Some regions have initial statistical support stronger than others, so these are more likely to be confirmed, but only by doing the assays and carefully evaluating what the data tell us will we know for sure which regions are confirmed. We do not expect all of our initially positive regions to be confirmed, but even if only one region is strongly confirmed this will be an extremely important advance, not only for TN1 but for the entire biomedical field of neuropathic pain in general. 2 Submitted January 3, 2018

Moreover, it is not enough to just find regions of the genome that harbor genes that cause TN1 – we also have to identify the specific genes and mutations in these genes that cause them to biologically malfunction, as this information is essential for translation to new therapies. It is possible that some of the mutations that cause TN1 are extremely rare, found only in TN1 patients and their close relatives. To discover additional TN1 genes and TN1-causing mutations, including those that are very rare, we will use the latest technologies for “reading” the DNA sequence of the entire human genome in a select subset of our TN1 patients. This method is called Next Generation Sequencing (NGS), and we propose to perform this assay for 100 TN1 patients.

Combining our previously-studied as well as our new TN1 cases gives us a sample of approximately 900 TN1 cases, of mostly Caucasian racial origin but with some non-Caucasians included too. Combining these with a similar number of controls will provide us with substantially increased statistical power to ask several very important questions such as the following: Do different genes cause TN1in young patients versus those who experience their first symptoms when older? (We already started to ask this first question in a limited way in the first phase of our research and with a larger sample can address this more rigorously.) Are there different genetic effects in males versus females, as found in many other genetic diseases? Are there different genes causing TN1 in the (typically younger) patients without vascular compression of their trigeminal nerve compared to patients whose trigeminal nerve has been damaged by years of vascular compression?

Our research may lead to a more complex picture of TN1 as being caused by not just mutations of just one gene, but in fact mutations found in several different genes may be associated with various subtypes of TN1. Genetics may reveal TN1 clinical subtypes that we currently do not even recognize exist, as has been found in numerous other neurological conditions including the epilepsies and the many forms of ataxia caused by different genes. While our primary goal remains identifying gene mutations that cause TN1, the research described here for the next phase of our study may also identify genetically distinct subgroups of TN1 patients as a very important secondary benefit of our genetic approach. Progress towards a cure (or, more likely, “cures”) will be more rapid and have greater chance of success if it is built on a foundation of knowledge about what is really going on biologically in different TN1 patients rather than if forced into a “one size fits all” therapeutic approach.

Project Timeframe: With adequate funding all research can be completed within one year. 3 Submitted January 3, 2018

Genetics Study

Brings Precision Medicine 

To Trigeminal Neuralgia

 By Scott Diehl

 The Genetics Study team supported by the Foundation has completed a search of over one million locations in the DNA of 348 Trigeminal Neuralgia (TN) patients. This “Big Data” effort has pointed to genes affecting excitability of neurons, nerve degeneration and responses to nerve injury. These genes are very strong suspects, and the team will now gather additional information from more patients and from a complementary approach that uses high speed DNA sequencing.

In the team's next effort, these genes will be tested in a new set of TN patients. 

If the same results are found again, this replication will be like lightning striking in the same place twice and confirm that mutations in these genes cause TN in some patients. These next steps are essential to confirm the initial findings and they may also reveal additional genes not detected with a strong enough signal in the initial search. Once confirmed, these discoveries will then be ready for testing in animals and translation to patients in the clinic. 

The genetics data gathered thus far are painting a complex picture of TN as being caused by not just mutations in any one gene. It appears more likely that several different genes are involved in different patients, a phenomenon known as “genetic heterogeneity.” For example, one of the most strongly supported genes is important only for TN patients whose symptoms first appeared after age 55. A different gene with different biological functions is implicated in patients who developed TN at a younger age. Genetic heterogeneity has been found in other neurological conditions including the epilepsies and the many forms of ataxia caused by different genes. This strategy, known as Precision Medicine, is a major US and International effort getting underway focusing on nearly all human health problems today (https://allofus.nih.gov/). 

While the primary goal of the genetics study is to identify gene mutations that cause TN, this research may also identify genetically distinct subgroups of TN patients as a very important secondary benefit. Progress towards a cure (or, more likely, “cures”) will be more rapid and have greater chance of success if built on a foundation of knowledge about what is really going on biologically in different TN patients rather than if forced into a “one size fits all” therapeutic approach. 

The Genetics Study Team supported by the Foundation is an international collaboration of leaders in the fields of neurosurgery, pain biology and human genetics at Oregon Health and Science University (Dr Kim Burchiel), The Hebrew University of Jerusalem (Dr Marshall Devor), the University of Toronto (Dr Ze’ev Seltzer) and Rutgers School of Dental Medicine (Dr Scott Diehl). Numerous additional locations have provided valuable assistance with recruiting patients.
