Can phenylketonuria cause convulsions?
Phenylketonuria can cause seizures. It is a common amino acid metabolic disorder, an autosomal recessive genetic disease caused by mutations in the phenylalanine hydroxylase gene. This leads to reduced or lost enzyme activity, causing the accumulation of phenylalanine and its metabolic products in the body, which leads to the disease. The incidence rate in China is about 1/16,500, with certain racial and regional differences. Clinically, it is characterized by delayed growth and intellectual development, seizures, hyperreflexia, eczema, etc.
Whooping cough occurs in children of what age?
Pertussis is an acute respiratory infectious disease caused by Bordetella pertussis infection, mainly characterized by paroxysmal spasmodic coughing, crowing inspiratory stridor, and the coughing often occurs at night. Pertussis can occur in both adults and children, but is more common in children. Children under the age of five are the most susceptible, especially infants who have not been vaccinated against pertussis. Children are generally vaccinated with the primary prophylaxis at the age of three to five months, receive a booster at 18-24 months, and another booster at the age of six. If pertussis occurs in adults, the condition is milder and the course of the disease is shorter.
Will there still be a lump on the belly button after umbilical hernia surgery?
Umbilical hernia refers to a bulge formed by the contents of the abdominal cavity protruding through a weak spot in the navel area, commonly seen in infants and young children. Most umbilical hernias can heal on their own within the first year as the umbilical fascial ring gradually contracts. Therefore, unless there is incarceration of the hernia, it is possible to observe and use non-surgical treatment before the age of two. When the child reaches two years of age and the diameter of the hernia exceeds 1.5 centimeters, surgical treatment is recommended. After the surgical treatment of the umbilical hernia, the bulge on the belly button will disappear. The surgery involves making a small incision at the lower edge of the navel, freeing the hernial sac, repositioning the herniated contents, and after excising part of the hernial sac at the hernial ring, suturing is performed.
Rickets are more commonly seen at a few months old.
Rickets often presents with square skull in babies older than 8 to 9 months. A normal baby’s skull is round and without angles. The square skull seen in rickets is due to a calcium deficiency in the bones, leading to poor development of cartilage and inability for bone deposition and calcification. This results in a large amount of osteoid deposition under the periosteum of the frontal, parietal, and occipital bones, thus forming angular shapes and a squared skull. Besides square skull, rickets can also manifest as various other skeletal abnormalities at different ages, including "ping pong ball" skull, funnel chest, pigeon chest, bracelet sign, rosary sign, X-shaped legs, and O-shaped legs.
Can a cold in children cause encephalitis?
Colds in children can potentially lead to encephalitis, and are generally referred to as upper respiratory tract infections in children. The pathogens can be bacteria, viruses, etc., typically manifesting as fever, runny nose, sneezing, coughing, sore throat, and more. Sometimes, gastroenteric colds can also manifest as nausea, vomiting, abdominal pain, diarrhea, etc. Because children have relatively lower immunity, if the infecting pathogen is highly toxic and aggressive, it can potentially cross the blood-brain barrier and enter the brain tissue, causing encephalitis. When encephalitis occurs in children, symptoms such as fever, seizures, and coma can appear, and neurological signs may be observed upon examination.
What to do if a child catches a cold and loses appetite?
When children catch a cold, bacteria or viruses may invade the gastrointestinal tract, affecting its function and causing a loss of appetite. Therefore, when children show symptoms of a cold, in addition to fever, runny nose, and cough, they may also experience poor appetite, abdominal pain, bloating, and even vomiting and diarrhea. When a child has a loss of appetite due to a cold, in addition to treating the symptoms with cold medicine, we can also provide a light diet, encourage more water intake, and give easily digestible, vitamin-rich foods. Additionally, administering Chinese herbal medicine to strengthen the spleen and stomach can be beneficial.
The types of infantile eczema can be divided into several categories.
Infant eczema can be divided into three types based on skin lesions. 1. Seborrheic type, commonly seen in infants aged one to three months, often on the forehead, cheeks, and between the eyebrows. The skin appears reddened and covered with yellow, greasy scales, with possibly thicker yellow serous crusts at the top. 2. Exudative type, often found in chubby infants aged three to six months, typically presenting symmetrically with small, millet-grain-sized red papules on the cheeks, accompanied by small vesicles and erythema. There can be patchy erosion with exudate, and thick yellow serous crusts. If not treated promptly, it can easily lead to secondary infections. 3. Dry type, more common in children aged six months to one year, characterized by papules, redness, hard bran-like scales, and crusts without exudation, also known as dry eczema.
Can mugwort be used for infant eczema?
Mugwort has the effects of removing cold, warming the meridians, and regulating qi. It has certain antiviral and bactericidal effects and can have a certain therapeutic effect on treating eczema. Mugwort treatment for eczema can take two methods: medicinal baths and oral administration. Generally, children use medicinal baths for treatment, but mugwort cannot completely cure eczema; it can only help alleviate the condition. Therefore, it is important for children to maintain a light diet, avoid contact with allergens, and it is best to go to the hospital for detailed and scientific diagnosis and treatment.
Phenylketonuria will be fine when grown up, right?
Phenylketonuria is an autosomal recessive genetic disorder, a congenital amino acid metabolism disorder caused by mutations in the phenylalanine hydroxylase gene. This mutation leads to decreased enzyme activity, causing phenylalanine and its metabolic products to accumulate in the body, thereby causing the disease. If diagnosed and treated early, a child's intelligence can remain normal, and abnormalities in the electroencephalogram can be restored. If uncontrolled, typical symptoms will appear as the child grows, including delayed growth and development, primarily manifested as delayed intellectual development, as well as seizures, light brown hair, and other symptoms.
Early symptoms and manifestations of umbilical hernia
Umbilical hernia is a common umbilical disease, characterized by the hernial sac protruding through the umbilical ring. This condition has a higher incidence rate in infants. As infants grow older, most cases can be resolved, but a few children may require surgical intervention. Early signs of umbilical hernia include a soft bulge and protrusion at the navel. The protrusion at the umbilical area may increase when the infant cries, coughs, defecates, or struggles due to increased abdominal pressure, and it can decrease or disappear when the infant is calm and asleep. However, if the child experiences severe abdominal pain or vomiting, this could be an indication of incarcerated umbilical hernia, and it is crucial to seek medical attention immediately.
