What are the clinical features of beta thalassemia?

In people with beta thalassemia, low levels of hemoglobin lead to a lack of oxygen in many parts of the body. Affected individuals also have a shortage of red blood cells (anemia ), which can cause pale skin, weakness, fatigue, and more serious complications.

Why does thalassemia cause facial bone deformity?

Thalassemia can make your bone marrow expand, which causes your bones to widen. This can result in abnormal bone structure, especially in your face and skull. Bone marrow expansion also makes bones thin and brittle, increasing the chance of broken bones.

Why does thalassemia cause chipmunk facies?

Chronic iron deposition due to multiple transfusions can result in bronze skin. Extramedullary expansion of hematopoiesis results in deformed facial and other skeletal bones and an appearance known as chipmunk face.

What causes bossing of the head and face in patients with thalassemia?

It is most common in people with sickle cell beta thalassemia. People with sickle cell beta thalassemia have 1 copy of the sickle hemoglobin gene and 1 copy of a mutated hemoglobin gene that lowers hemoglobin production. Skull bossing happens when bone marrow in the skull expands.

What clinical characteristics might a person with beta thalassemia intermedia exhibit?

You may notice some “bony changes” in the face; the forehead or the cheek bones may appear to protrude, or he or she may appear to have “buck teeth”. These changes are due to the bone marrow working extra hard to make red blood cells.

What does a CBC look like with thalassemia?

A complete blood count (CBC), which includes measures of hemoglobin and the quantity (and size) of red blood cells. People with thalassemias have fewer healthy red blood cells and less hemoglobin than normal; those with alpha or beta thalassemia trait may have smaller-than-normal red blood cells.

Is beta thalassemia painful?

Two-thirds of the patients reported repeated pain episodes each month, and 20 percent reported daily pain. The prevalence and severity of pain correlated with age of the patient. As patients age, pain becomes a more prominent problem in their lives. Most patients have back pain.

What is the difference between alpha thalassemia and beta thalassemia?

The thalassemias are a group of inherited hematologic disorders caused by defects in the synthesis of one or more of the hemoglobin chains. Alpha thalassemia is caused by reduced or absent synthesis of alpha globin chains, and beta thalassemia is caused by reduced or absent synthesis of beta globin chains.

What is chipmunk face?

Names like “chipmunk cheeks” or “baby face” have been coined to describe the full cheek appearance associated with excess buccal fat. Full, rounded cheeks can be reduced (and sucked in) and cheek bones better defined with buccal fat removal.

What causes a protruding forehead?

They can be hormonal disorders, genetic or inherited syndromes, or others. A common cause of frontal bossing is acromegaly, which is a hormonal disorder caused when the pituitary gland releases too much growth hormone. This excess leads to the bones of the face, skull, jaw, hands, and feet being enlarged.

What does a prominent brow bone mean?

Large or prominent brow bones are a direct result of the development of the underlying frontal sinus air cavity. Thus they are not just very thick bones and this plays a major factor in what type of brow bone reduction surgery may be most beneficial.

Is beta thalassemia rare?

Beta thalassemia is relatively rare in the United States, but is one of the most common autosomal recessive disorders in the world. The incidence of symptomatic cases is estimated to be approximately 1 in 100,000 individuals in the general population.

Can thalassemia get Covid vaccine?

As thalassemia is considered to be a severe underlying medical condition, both adults and children with thalassemia were excluded from the COVID-19 vaccine clinical trials.

Why can’t thalassemia take iron?

People with thalassaemia may be advised to avoid iron supplements because they are at risk of iron overload. Carriers of the thalassaemia gene may be asymptomatic but pregnancy can precipitate anaemia and there is a chance that this may be inappropriately treated with iron replacement.

Which type of thalassemia is worse?

Different people will have different symptoms, based on which type of the disorder is inherited. Beta thalassemia major: This is the most severe type of this disorder. Children born with this type will have symptoms early in life that include: Pale skin.

What is pillow face?

“Pillow face” is a direct play on the puffy, unattractive result of using too much facial filler or transferred fat. Another term often used to describe this overfilled look is “chipmunky.”

Why does pillow face happen?

Pillow face is generally the result of poor technique and over-injection. Injecting more filler does not maximize results, it diminishes them. An experienced injector will possess an excellent sense of visual balance.

Why is my child’s forehead so big?

The large, bulging forehead is a sign of the body protecting itself — the child’s skull is compensating for the premature fusion and allowing normal brain growth to continue. The long, narrow skull that results from sagittal synostosis is known as scaphocephaly, sometimes referred to as a “boat shape.”
