The Year of the Zebra

What is this initiative?

2023 is the 40th anniversary of the Orphan Drug Act which gave hope to the hundreds of millions of people around the world who are directly affected by rare disorders (also known as “zebras,” because they are less common than horses). Elsevier Health is launching an ambitious initiative called “The Year of the Zebra” to educate millions of current and future healthcare professionals, caregivers, researchers, patients, family members, and the general public about these zebras. We are inviting an exclusive group of organizations and individuals to “adopt” one or more zebras by contributing to the development and distribution of highly engaging and impactful educational content about those rare disorders that will collectively reach millions of people around the world. 

Rare Disease Day

Tuesday, February 28th is Rare Disease Day, when the world comes together to show support for the 400+ million people inflicted by 7,000+ rare diseases globally and those who care for them! It is also the day that Osmosis from Elsevier launches our global Year of the Zebraeducation initiative to drive more awareness of and support for rare diseases in the healthcare community. 

The first Rare Disease Day was celebrated on February 29th, 2008 - the rarest day given that it only occurs every Leap Year. Since then, Rare Disease Day has been celebrated on the last day of February. This year it falls on Tuesday, February 28th.

Importantly, that first Rare Disease Day back in 2008 marked the 25th anniversary of the Orphan Drug Act, which revolutionized the way treatments and cures are developed for rare diseases. Today, fifteen years later, the Year of the Zebra is a renewed commitment to achieving an inclusive healthcare system, to educating as many people as possible, and to leveraging Osmosis’ far-reaching network of followers and subscribers to ultimately drive research, action, and improve patient outcomes.

Moving forward, each week, we will continue to feature one new video highlighting a rare disease or “zebra”. That video will also be featured on the new Elsevier Rare Diseases Healthcare Hub, a global hub, available to all, that will feature the very latest research affecting patients and featuring the latest research, developments, and education materials for the rare disease community. The Year of the Zebra initiative will also see the launch of Elsevier’s new journal dedicated to the topic – Rare. Open Research in Rare Diseases.

Please help us spread the word about this worthy and important initiative in the year ahead.

Introducing Rare: Open Access Journal

Rare is a new Gold Open Access journal that publishes international research on direct clinical and psychosocial care, diagnosis, pharmacology, public policies or ethics. Rare includes rigorously peer-reviewed articles on research that improves the well-being and quality of life of patients with rare diseases - as well as undiagnosed, unsolved disorders - and their families.

Through Rare, researchers, healthcare professionals, policy makers, and the rare disease community have a multidisciplinary open access scientific journal that covers all aspects of living with these disorders.

Editor in Chief: Prof. Dr. Wendy van Zelst-Stams, Radboud University Medical Centre in Nijmegen, The Netherlands

The Zebra of the Week is: Syringomyelia

The smooth flow of a river along its path allows everything around it to act as intended; whole ecosystems can flourish on its banks along either side. If, for instance, a massive rockslide were to block the flow of water, it would pool behind the obstacle and cause damage to any structure that happens to be in its expanding path. This is similar to what happens when syringomyelia, today’s zebra, is caused by the brain abnormality called the Chiari malformation.

The cerebrospinal fluid flows in the spinal canal and all around the central nervous system. Syringomyelia is a rare condition characterized by a fluid-filled cavity or cyst known as a syrinx that forms within the spinal cord. This syrinx can expand over time compressing or destroying the surrounding nerve tissue, leading to symptoms such as pain, burning, tingling, or numbness in the affected areas especially the upper limbs and torso. Muscle weakness and wasting may progressively occur, leading to paralysis in severe cases. Particularly in children, who are in a growth phase, skeletal abnormalities such as scoliosis may arise.

The symptoms are usually most prominent between the ages of 20 and 40 years. Diagnosis is usually clear on magnetic resonance imaging (MRI).

To learn more about the mechanisms and treatment of syringomyelia, watch the dedicated Osmosis video on YouTube and Osmosis.org

Meet Dr. Miguel

As our Year of the Zebra focus on rare diseases continues, we’re putting several neurological conditions in the spotlight on the above Raise the Line Podcast Episode. Their symptoms include neck pain, vertigo, swallowing issues, memory trouble and many more: idiopathic syringomyelia; idiopathic scoliosis; and the Arnold-Chiari Syndrome type 1 caused variously by cavities in the spinal cord and brain herniation.

Fortunately, our guide is one of the world’s leading experts in this area, Dr. Miguel Bautista Royo-Salvador, Director of the Institut Chiari & Siringomielia & Escoliosis de Barcelona, and President of the Chiari and Scoliosis and Siringomielia Foundation.  In his fifty-plus years of focus on these conditions, Dr. Royo-Salvador has alternated between research activity and clinical practice in which he applies a treatment method he developed called the Filum System.  Inventing this new approach was sparked by a patient who experienced very little improvement from what was the standard surgical treatment at the time. “I have come to the conclusion that an abnormally intense caudal traction of the entire central nervous system is the cause of the descent of the cerebellar herniation in Chiari Syndrome type 1, as well as of scoliosis and syringomyelia and others. To speak figuratively, it's like a pull from below on the whole central nervous system,” he explains to host Michael Carrese.

After 2,100 procedures with a subjective improvement rate of 95%, Dr. Royo-Salvador and the Institute are working to broaden awareness of this minimally invasive approach.  Tune-in for an educational journey into these rare conditions and a proven technique to relieve patient suffering.
