Will pediatric allergic eczema be contagious?
Childhood allergic eczema is not a contagious disease, so it is not transmissible. Eczema is a common skin allergic disease during infancy and early childhood, characterized by rashes and skin itching. The rash mostly appears on the neck, the perineum, and other areas, often recurring. The onset in some children is related to family genetics. When children develop eczema, they can apply calamine lotion topically or take antihistamine medication orally under the guidance of a doctor to relieve symptoms of skin itching. In terms of diet, it is advisable to avoid allergenic foods such as fish, shrimp, eggs, and seafood.
What to do about nasal congestion in children after a cold?
After a child catches a cold and exhibits symptoms of nasal congestion, antihistamine medication can be taken orally under the guidance of a doctor to relieve nasal congestion. Local use of nasal drops or saline solution, or the use of nasal spray locally can also relieve symptoms of nasal congestion. When a child has a cold causing nasal congestion, it is mostly because the nasal mucosa becomes congested and swollen after the cold, leading to the symptoms of nasal congestion. Some children may develop symptoms of allergic rhinitis after a cold. In addition to nasal congestion, most children may also experience symptoms such as a runny nose and sneezing.
Why can't you cry with an umbilical hernia?
In children with umbilical hernia, crying can easily lead to an increase in intra-abdominal pressure. As the intra-abdominal pressure increases, gas in the intestines and mesentery can easily protrude through the unclosed umbilical ring, thereby exacerbating the symptoms of the umbilical hernia. In severe cases, this could lead to serious complications such as incarceration of the hernia. Therefore, in addition to not crying, children with an umbilical hernia should also avoid constipation, coughing, and vigorous activities that could increase intra-abdominal pressure, in order to prevent worsening of the hernia symptoms. In daily life, their diet should be light and easy to digest.
The umbilical hernia in the baby healed, but occurred again after two months. What should I do?
The baby's umbilical hernia had healed for two months but reappeared, indicating that the umbilical ring has not closed and the hernia has not completely healed. Therefore, in daily life, it is important to minimize the child's crying, tantrums, and vigorous exercise, and avoid getting cold or sick as much as possible to prevent severe coughing. Attention should be paid to the intake of foods rich in vitamins and cellulose, such as fresh vegetables and fruits. Drink plenty of water, maintain smooth bowel movements, and follow a light diet. Avoid eating cold and spicy foods.
Can an umbilical hernia often be pressed with hands?
Umbilical hernias can often be pressed with the hand, but it is important to be careful with the technique and strength used to avoid damaging the contents of the hernia or the local skin, which could lead to a secondary bacterial infection. Umbilical hernia is one of the common diseases during the newborn and infant periods. After the umbilical cord falls off, if the closure of the umbilical ring is incomplete or the tissues around the navel are not sturdy, factors such as frequent crying or constipation can increase intra-abdominal pressure. This can lead to the protrusion of abdominal contents, particularly the small intestine along with the peritoneum and abdominal wall skin, gradually pushing outward at the umbilicus, forming an umbilical hernia.
Does precocious puberty require growth hormone treatment?
For children with precocious puberty, a small number require combined treatment with growth hormones. For instance, if a child's height growth rate is less than 4cm, it is necessary to add growth hormones to promote growth and development. The second scenario involves using a bone age test; if the height is less than 151cm, growth hormones can also be used in combination for treatment. In the third scenario, if the child's bone age at the time of consultation has already exceeded 11.5 years, has significantly increased, or even if menstruation has started and their height has been clearly affected, it is generally advised to use growth hormones in combination with treatment.
What to eat for lactose intolerance as supplementary food?
Children with lactose intolerance should avoid adding foods containing lactose when introducing solid foods. Additionally, you can make some food at home for the baby, such as cooking thin porridge, boiling noodles for the baby, mixing a lumpy soup, etc. You can also give the baby small amounts of fruits and vegetables, but they need to be cut into small pieces or juiced before feeding. The main treatment for lactose intolerance is dietary therapy, which involves avoiding foods containing lactose to effectively control and alleviate the symptoms of lactose intolerance in babies, such as milkshakes, cheese, and other dairy products which should not be fed to the baby.
The precocious puberty stimulation test is used to check for what?
The precocious puberty stimulation test, also known as the luteinizing hormone-releasing hormone stimulation test. The method of examination involves administering an intravenous injection of gonadotropin-releasing hormone, followed by taking blood samples before the injection, and at 30, 60, 90, and 120 minutes after the injection. Serum levels of luteinizing hormone and follicle-stimulating hormone are measured to assess their peak values. This can diagnose whether the gonadal axis has been activated and is a reliable method for diagnosing precocious puberty.
What symptoms will appear in the pituitary gland with precocious puberty?
Children with precocious puberty should undergo a pituitary gland examination, which may reveal symptoms in two aspects: 1. Imaging examination such as pituitary MRI, which might uncover tumors in the pituitary gland that could lead to precocious puberty. 2. Hormone level tests, mainly involving the secretion of hormones controlled by the hypothalamic-pituitary-gonadal axis. For example, the secretion of gonadotropin-releasing hormone, luteinizing hormone, and follicle-stimulating hormone can cause precocious puberty. Precocious puberty is a relatively common endocrine disorder in children. Generally, it can be diagnosed in girls before the age of eight and in boys before the age of nine if secondary sexual characteristics appear.
Can children have glaucoma?
Children can develop glaucoma. Congenital glaucoma typically presents within the first year of life and is more common in boys. The disease onset before the age of two to three years leads to increased eye pressure, which results in the enlargement of the eyeball. This manifests as photophobia, tearing, and eyelid spasms. Once diagnosed, early surgical treatment is recommended. For children under three years old, the preferred surgical procedures are trabeculectomy or goniotomy. As children are in a developmental stage and have poorer overall tolerance, anti-glaucoma medications are only suitable for short-term bridging treatment.
