Day 6: Cushing’s Awareness Challenge

The above is the official Cushing’s path to a diagnosis but here’s how it seems to be in real life:

Egads!  I remember the naive, simple days when I thought I’d give them a tube or two of blood and they’d tell me I had Cushing’s for sure.

Who knew that diagnosing Cushing’s would be years of testing, weeks of collecting every drop of urine, countless blood tests, many CT and MRI scans…

Then going to NIH, repeating all the above over 6 weeks inpatient plus an IPSS test, an apheresis (this was experimental at NIH) and specialty blood tests…

The path to a Cushing’s diagnosis is a long and arduous one but you have to stick with it if you believe you have this Syndrome.

PET/MRI may improve diagnosis of Cushing disease

PET/MRI could become the diagnostic method of choice over MRI alone for identifying small pituitary tumors associated with Cushing disease, according to a study published March 21 in the Journal of Nuclear Medicine.

In patients diagnosed with the disease yet who had inconclusive MRI results, PET/MRI was positive in 100% of cases, noted lead author Ilanah Pruis, a doctoral student at Erasmus University Medical Center in Rotterdam, Netherlands.

“This multimodal imaging technique provides a welcome improvement for diagnosis, planning of surgery, and clinical outcome in patients with Cushing disease,” the authors wrote.

Cushing disease is characterized by small tumors in pituitary glands, which causes them to secrete excess cortisol, the authors explained. While it is a rare disease, over time it can cause severely disabling conditions, such as high blood pressure or type II diabetes.

Currently, guidelines recommend the use of MRI and inferior petrosal sinus sampling (IPSS) to diagnose these tumors. IPSS is an invasive procedure in which cortisol hormone levels are sampled from the veins that drain the pituitary gland.

In up to 40% of patients, however, MRI is inconclusive, as the lesions are smaller than 10 millimeters in diameter. Even advanced MRI techniques, such as dynamic perfusion imaging, can leave small lesions undetected in up to one third of patients, the authors noted.

In preclinical work, PET imaging using a radiotracer named F-18 FET has been shown to bind with high affinity to a molecular target in pituitary tumors, and in this study, the researchers aimed to test this technique combined with MRI in a multimodal approach.

The researchers analyzed results from 22 patients (68% women; mean age 48 years) who underwent F-18 FET PET/MRI at Erasmus MC between February 2021 and December 2022. All patients showed a clear pituitary tumor F-18 FET-PET/MRI, whereas reading of the MRI alone yielded a suspected lesion in only 50%, the authors found.

T1-weighted postgadolinium MR images (A and C) and F-18 FET-PET/MR images (B and D) centered at pituitary before (A and B) and after (C and D) transsphenoidal surgery. This patient with Cushing disease showed clear focal uptake (B) but no clear lesion on previously obtained and accompanying MRI (A). Postoperative tissue analysis did confirm resection of small pituitary adenoma/PitNET, and postoperative F-18 FET-PET showed no residual uptake (D).

Importantly, 16 patients underwent treatment based on the results — either surgery, Gamma Knife, or CyberKnife therapy — with 12 of these patients achieving short-term remission, the authors noted.

“[F-18 FET-PET/MRI] is of great clinical value because it allows precision surgery and targeted Gamma Knife or CyberKnife therapy,” the group wrote.

The researchers noted that only one previous study evaluated F-18 FET-PET/MRI in these patients and that their study was limited, given the relatively small number of patients.

“Future studies will be directed at head-to-head comparisons of the performance of F-18 FET- PET and other diagnostic techniques, including advanced MRI sequences… preferably in patients at the time of initial clinical presentation,” the authors concluded.

Day 5, Cushing’s Awareness Challenge

In Day 9 on April 9, 2015, I wrote about how we got the Cushing’s colors of blue and yellow.  This post is going to be about the first Cushing’s ribbons.

I was on vacation  in September, 2001 when SuziQ called me to let me know that we had had our first Cushie casualty (that we knew about).

On the message boards, Lorrie wrote: Our dear friend, Janice died this past Tuesday, September 4, 2001. I received an IM from her best friend Janine, tonight. Janine had been reading the boards, as Janice had told her about this site, and she came upon my name and decided to IM me. I am grateful that she did. She said that she knew that Janice would want all of us to know that she didn’t just stop posting.

For all of the newcomers to the board that did not know Janice, she was a very caring individual. She always had something positive to say. Janice was 36 years old, was married and had no children. She had a miscarriage in December and began to have symptoms of Cushing’s during that pregnancy. After the pregnancy, she continued to have symptoms. When discussing this with her doctor, she was told that her symptoms were just related to her D&C. She did not buy this and continued until she received the accurate diagnosis of Cushing’s Syndrome (adrenal) in March of 2001. Tragically, Janice’s tumor was cancerous, a very rare form of Cushing’s.

Janice then had her tumor and adrenal gland removed by open adrenalectomy, a few months ago. She then began chemotherapy. She was very brave through this even though she experienced severe side effects, including weakness and dizziness. She continued to post on this board at times and even though she was going through so much, she continued with a positive attitude. She even gave me a referral to a doctor a few weeks ago. She was my inspiration. Whenever I thought I had it bad, I thought of what she was dealing with, and I gained more perspective.

Janice was having difficulty with low potassium levels and difficulty breathing. She was admitted to the hospital, a CT scan was done and showed tumor metastasis to the lungs. She then was begun on a more aggressive regimen of chemo. She was discharged and apparently seemed to be doing well.

The potassium then began to drop again, she spiked a temp and she was again admitted to the hospital. She improved and was set to be discharged and then she threw a blood clot into her lungs. She was required to be put on a ventilator. She apparently was at high risk for a heart attack. Her husband did not want her to suffer anymore and did not want her to suffer the pain of a heart attack and so chose for the doctors to discontinue the ventilator on Tuesday. She died shortly thereafter.

Janice was our friend. She was a Cushie sister. I will always remember her. Janine asked me to let her know when we get the Cushing’s ribbons made as she and the rest of Janice’s family would like to wear them in her memory. She said that Janice would want to do anything she could to make others more aware of Cushing’s.

The image at the top of the page shows the first blue and yellow ribbon which were worn at Janice’s funeral.  When we had our “official ribbons” made, we sent several to Janice’s family.

Janice was the first of us to die but there have been more, way too many more, over the years.  I’ll write a bit more about that on Day 21.

Day 4, Cushing’s Awareness Challenge

This is one of the suggestions from the Cushing’s Awareness Challenge post:

“Give yourself, your condition, or your health focus a mascot. Is it a real person? Fictional? Mythical being? Describe them. Bonus points if you provide a visual!”

 

Our “Official mascot” is the zebra.

Our mascot

Our mascot

In med school, student doctors are told “When you hear hoofbeats, think horses, not zebras“.

According to Wikipedia: “Zebra is a medical slang term for a surprising diagnosis. Although rare diseases are, in general, surprising when they are encountered, other diseases can be surprising in a particular person and time, and so “zebra” is the broader concept.

The term derives from the aphorism ‘When you hear hoofbeats behind you, don’t expect to see a zebra’, which was coined in a slightly modified form in the late 1940s by Dr. Theodore Woodward, a former professor at the University of Maryland School of Medicine in Baltimore.  Since horses are the most commonly encountered hoofed animal and zebras are very rare, logically you could confidently guess that the animal making the hoofbeats is probably a horse.

By 1960, the aphorism was widely known in medical circles.”

Why? Because those of us who DO have a rare disorder know from personal experience what it feels like to be dismissed by a doctor or in many cases, multiple doctors. Many physicians have completely lost the ability to even imagine that zebras may exist!  Cushing’s is too rare – you couldn’t possible have that.  Well… rare means some people get it.  Why couldn’t it be me?

Although one of my signature images has a zebra, many have rainbows or butterflies in them so I guess that I consider those my own personal mascots.

I posted this in 2010 in 40 Days of Thankfulness: Days Twenty-Two through Thirty

I have a special affinity for rainbows. To me, a rainbow is a sign that things are going to be ok.

Years ago, our little family was in Florida. I felt guilty about going because my dad was terminally ill with his second bout of colon cancer. I was worried about him and said a little prayer for him.

I was lying on the beach while DH and our son were in the ocean and I looked up and saw a rainbow. It was a perfectly clear, sunny afternoon. I even called the people out of the water, in case it was something I wanted to see that didn’t really exist. They saw it, too.

Where in the world did that rainbow come from, if it wasn’t a sign that everything would be ok?

Butterflies are something else again.  I like them because I would like to think that my life has evolved like a butterfly’s, from something ugly and unattractive to something a big easier on the eye.

My Cushie self was the caterpillar, post-op is more butterfly-ish, if not in looks, in good deeds.

From July, 2008

For as long as I can remember, I’ve loved butterflies for their beauty and what they stood for. I’ve always wanted to shed my cocoon and become someone else, someone beautiful, graceful.

One of my first memories as a kid was knocking on the back door of my house and when my mom answered, I’d pretend to somehow be an orphan, looking for some kind person to take me in. And I would try to be that different child, with new habits, in the hopes that my parents would somehow think better of me, love me more as this poor homeless kid than they did as their own.

The butterfly was trying to emerge but it never got too far. Somehow, I would slip into my original self and be a bother to my parents.

Hope springs eternal, though!

Day 3: Cushing’s Awareness Challenge

me-tired

Sleep.  Naps.  Fatigue, Exhaustion.  I still have them all.  I wrote on my bio in 1987 after my pituitary surgery “I am still and always tired and need a nap most days. I do not, however, still need to take whole days off just to sleep.

That seems to be changing back, at least on the weekends.  A recent weekend, both days, I took 7-hour naps each day and I still woke up tired. That’s awfully close to taking a whole day off to sleep again.

In 2006, I flew to Chicago, IL for a Cushing’s weekend in Rockford.  Someone else drove us to Lake Geneva, Wisconsin for the day.  Too much travel, too Cushie, whatever, I was too tired to stay awake.  I actually had put my head down on the dining room table and fallen asleep but our hostess suggested the sofa instead.  Amazing that I traveled that whole distance – and missed the main event 😦

This sleeping thing really impacts my life.  Between piano lessons, I take a nap.  I sleep as late as possible in the mornings and afternoons are pretty much taken up by naps.  I nod off at night during TV. One time I came home between church services and missed the third service because I fell asleep.

I only TiVo old tv shows that I can watch and fall asleep to since I already know the ending.

Since  mid-February, I have been doing physical therapy twice a week for 2 hours at a time for a knee injury (read more about that in Bees Knees).  I come home from that exhausted – and in more pain than I went.  I know it’s working and my knee is getting better, but it’s such a time and energy sapper.  Neither of which I can really spare.

Maybe now that I’m nearly 10  years out from my kidney cancer (May 9, 2006) I could theoretically go back on Growth Hormone again.  My surgeon says he “thinks” it’s ok.  I’m sort of afraid to ask my endo about it, though.  I want to feel better and get the benefits of the GH again but I don’t want any type of cancer again and I certainly can’t afford to lose another kidney.

I’ll probably just muddle through without it.  I always laugh when I see that commercial online for something called Serovital.  I saw it in Costco the other day and it mentions pituitary right on the package.  I wish I could take the people buying this, sit them down and tell them not to mess with their pituitary glands.  But I won’t.  I’ll take a nap instead because I’m feeling so old and weary today, and yesterday.

And tomorrow…
