MEDICAL CODING IN CALICUT

 G93.7

 (REYE'S SYNDROME)

                                       Reye's (Reye) syndrome is a rare but serious condition that causes swelling in the liver and brain. Reye's syndrome most often affects children and teenagers recovering from a viral infection. Aspirin has been linked with Reye's syndrome, so use caution when giving aspirin to children or teenagers for fever or pain. Though aspirin is approved for use in children older than age 3, children and teenagers recovering from chickenpox or flu-like symptoms should never take aspirin. Reye's syndrome usually occurs in children who have had a recent viral infection, such as chickenpox or the flu. Taking aspirin to treat such an infection greatly increases the risk of Reye's. Both chickenpox and the flu can cause headaches. That's why it's important to not use aspirin to treat a child's headache.

    

SYMPTOMS

                      In Reye's syndrome, a child's blood sugar level typically drops while the levels of ammonia and acidity in his or her blood rise. At the same time, the liver may swell and develop fatty deposits. Swelling may also occur in the brain, which can cause seizures, convulsions or loss of consciousness.

                               The signs and symptoms of Reye's syndrome typically appear about three to five days after the onset of a viral infection, such as the flu (influenza) or chickenpox, or an upper respiratory infection, such as a cold.

•        Irritable, aggressive or irrational behavior

• Confusion, disorientation or hallucinations
• Weakness or paralysis in the arms and legs
• Seizures
• Excessive lethargy
• Decreased level of consciousness

Clinical Information

• A form of encephalopathy with fatty infiltration of the liver, characterized by brain edema and vomiting that may rapidly progress to seizures; coma; and death. It is caused by a generalized loss of mitochondrial function leading to disturbances in fatty acid and carnitine metabolism.
• A rare disease that damages the brain and liver and causes death if not treated. It occurs most often in children younger than 15 years who have had a fever-causing virus, such as chickenpox or flu. Taking aspirin during a viral illness may increase the risk of reye syndrome.
• An acute and potentially fatal metabolic disorder characterized by cerebral edema, fatty liver and hypoglycemia. It occurs primarily in children and has been associated with the use of aspirin for the treatment of viral infections. However, it can also occur in the absence of aspirin use.
• Rare, acute, sometimes fatal disease of childhood, most often occurring as a sequel of varicella or a viral upper respiratory infection of childhood; marked by recurrent vomiting and elevated serum transaminase levels with distinctive changes in the liver and other viscera; an encephalopathic phase with acute brain swelling disturbances of consciousness and seizures may follow.
• Reye syndrome is a rare illness that can affect the blood, liver and brain of someone who recently had a viral infection. It always follows another illness. Although it mostly affects children and teens, anyone can get it. It can develop quickly and without warning. It is most common during flu season. Symptoms include

• nausea and vomiting
• listlessness
• personality change - such as irritability, combativeness or confusion
• delirium
• convulsions
• loss of consciousness

if these symptoms occur soon after a viral illness, seek medical attention immediately. Reye syndrome can lead to a coma and brain death, so quick diagnosis and treatment are critical. Treatment focuses on preventing brain damage. There is no cure.the cause of reye syndrome is unknown. However, studies have shown that taking aspirin increases the risk of getting it. Because of that, health care professionals now recommend other pain relievers for young patients.
