hy do people with stone man syndrome have different toes
Fibrodysplasia ossificans progressiva (FOP), an extremely rare connective tissue disease, has not only attracted widespread medical attention, but also raised countless questions due to its unique clinical manifestations. According to medical research, the disease is characterized by abnormal ossification of fibrous connective tissues such as muscles, tendons and ligaments, which causes the originally flexible limbs to gradually become stiff, eventually causing the patient's entire body to become almost completely "petrified". However, why the toes of people with stone man syndrome are different has become a focus of research.
Abnormal formation of toes
People with stone man syndrome are often born with malformed toes, especially the big toe, which may be missing joints or have a noticeable lump over the small joint.
Studies have shown that these abnormal toes are caused by mutations in the ACVR1 gene. The mutation alters the body's repair mechanism, causing normal muscle and connective tissue to generate bone tissue. As these patients enter their growth phase, most will have their first onset before the age of ten, and as the disease progresses, bone growth usually progresses from the upper part of the body to the lower part.
In people with FOP, abnormalities in the toes may be one of the earliest signs of the disease. This abnormal formation not only causes differences in appearance, but also gradually begins to affect the patient's walking and movement abilities. In fact, the big toe of these patients gradually becomes inflexible and cannot even be placed flat on the ground normally.
Changes in the course of the disease
According to current observations, bone formation in FOP patients begins in the neck, then spreads to the shoulders, arms and chest, and finally to the feet. Inflamed or tender areas of the ankles and feet are often the most susceptible to growths. During the aggressive bone formation process, the joints in this area often lose their ability to move. This not only makes daily life difficult for patients, but may also affect their ability to speak and eat.
Medical diagnosis and difficulties
Due to its rarity, FOP is often misdiagnosed as cancer or other conditions, which can lead doctors to order a biopsy, which can exacerbate the bone-building process.
Radiologic tests, such as X-rays, are key in diagnosing FOP. Accurately reporting the patient's family history and the abnormal appearance of the big toe to the physician can aid in early diagnosis and appropriate medical intervention. However, due to the lack of knowledge about the disease in the medical community, diagnosis is often delayed for many patients, further prolonging the progression of the disease.
The Quest for Treatment
Currently, there is no cure for FOP and the main treatment options include symptomatic treatments to reduce inflammation and control pain. In particular, anti-inflammatory drugs are often used to reduce inflammation during flare-ups to relieve pain in patients. However, surgery should never be performed to remove excess bone, as this often leads to more bone formation problems. Instead, new treatments like Sohonos (palovarotene) offer a glimmer of hope and a new hope for treatment.
Future Research Directions
Today, some progress has been made in the research on stone man disease, especially in gene therapy and targeted treatment. Researchers are working to develop treatments that target the mutated ACVR1 gene, which could potentially change the quality of life and life expectancy of people with FOP.
While reviewing history, we may need to think about: When faced with such a rare and difficult-to-treat disease, how should society provide support and care so that patients and their families are no longer alone?
