Neonatal jaundice, how many days can it completely subside?
Neonatal jaundice is one of the common symptoms in newborns, especially in early newborns. Neonatal jaundice can be a normal physiological phenomenon, but it can also be a manifestation of certain diseases. Generally, if it is physiological jaundice in full-term babies, it usually resolves within about ten days, and generally lasts no longer than two weeks. In premature babies, it tends to last longer, generally not exceeding four weeks. However, if the jaundice persists for a long time, progresses quickly, and is severe, it may be pathological jaundice. Pathological jaundice might be associated with other discomforts, and in such cases, it is necessary to identify possible pathological factors and treat them accordingly to gradually control and reduce the jaundice. Therefore, if the jaundice persists for a long time, it is advisable to go to the hospital for some relevant tests to determine its nature, and if it is pathological jaundice, timely intervention and treatment are recommended.
The difference between pigeon chest and funnel chest
Pigeon chest is a common thoracic deformity characterized by a protruding sternum, generally believed to be related to genetics, and most consider it caused by excessive growth of the ribs and costal cartilage. The deformity of the sternum is secondary to the deformity of the ribs. Funnel chest, on the other hand, refers to the inward concavity of the lower part of the sternum, along with the neighboring ribs and costal cartilages, forming a funnel-like appearance, a type of congenital thoracic deformity more common in males than females. The etiology of funnel chest is relatively complex; it might involve the gradual worsening of the sternum being pulled at various levels during growth and development. It could also be due to excessive growth of the ribs on both sides, pressing the sternum backward, leading to the formation of funnel chest. Some also consider it a sex-linked dominant hereditary disease. The thoracic deformity in pigeon chest primarily protrudes outward, whereas in funnel chest, it concaves inward, and the causes are also different.
How long to take aspirin for Kawasaki disease
The current pathogenesis of Kawasaki disease is not yet clear, but one of its main pathological changes is a systemic vasculitis. During an outbreak of Kawasaki disease, the blood viscosity increases primarily due to platelet aggregation. Typically, oral aspirin is administered to prevent this inflammation and to treat platelet aggregation. The dosage is generally reduced gradually once the fever subsides, with maintenance doses lasting about six to eight weeks. If coronary artery lesions are present, the duration of medication is extended until the coronary arteries return to normal before discontinuing the drug.
normal values of neonatal jaundice
Neonatal jaundice is the most common phenomenon in the neonatal period, generally divided into physiological jaundice and pathological jaundice. If the baby's values are within the normal range, it may be physiological jaundice, which does not require special intervention and will resolve on its own. Typically, normal physiological jaundice appears 2-3 days after birth, peaks around 4-5 days, begins to lessen about a week later, and resolves within two weeks, generally occurring in full-term infants born after 37 weeks. It's advisable for babies to have their jaundice monitored daily within the first two weeks, especially during the peak period, from 2-3 days to about a week or around ten days, when jaundice monitoring should be more frequent. Normally, it's best if the bilirubin levels in newborns do not exceed 6 mg/dL in the first 24 hours, 9 mg/dL within 24-48 hours, 12 mg/dL within 48-72 hours, and 15 mg/dL after 72 hours. These values are generally considered acceptable. Additionally, jaundice progression should not be too rapid; if bilirubin levels rise more than 5 mg/dL within 24 hours, it indicates too rapid an increase in jaundice. In such cases, it is also necessary to go to the hospital, where a neonatal doctor should assess the baby and decide if special treatment intervention is needed.
What should not be eaten with Kawasaki disease?
One of the main pathological changes in Kawasaki disease is systemic vasculitis. Clinically, common symptoms include fever, high fever, recurrent fever, conjunctival congestion, significant oral mucosal congestion, strawberry tongue, enlargement of neck lymph nodes, and peeling of the hands and feet. In cases of Kawasaki disease, oral mucosal congestion is a common complication, hence during the period of Kawasaki disease, it is advised not to consume irritating, spicy, or hot foods. These might exacerbate the child's discomfort, affect their nutrient absorption, and potentially worsen the condition. Therefore, during the illness, it is preferable to focus on bland, easy-to-digest foods.
Is Kawasaki disease contagious?
Kawasaki disease, also known as mucocutaneous lymph node syndrome, currently has unclear pathogenic mechanisms and the causes of the disease are not well defined. One of its main pathological changes is systemic vasculitis, including the coronary arteries. The disease occurs sporadically or in small epidemics, can happen in any season without clear seasonality, and is generally more common in infants and young children, with eighty percent under five years of age. Kawasaki disease is not a contagious disease, so it does not have significant contagiousness.
How long does vomiting last in children with sudden rash?
Roseola in infants is a common febrile rash disease in toddlers, generally caused by a viral infection. The primary clinical manifestations of roseola include high fever lasting 3-5 days. Typically, rash develops as the fever subsides or after the fever has resolved. Some children may also experience other symptoms, such as coughing, nasal congestion, runny nose, and sometimes vomiting or diarrhea. Roseola is generally a self-limiting disease; the rash and other symptoms usually disappear gradually after the fever resolves. However, if roseola is accompanied by other viral or bacterial infections, the duration of the illness or symptoms may be prolonged. Since each child is different, the duration of symptoms like vomiting in roseola varies from one child to another, and there is no specific timeframe.
Neonatal jaundice symptoms
Neonatal jaundice is most commonly seen in the skin and mucous membranes, and the sclera, or what we refer to as the eyes, presenting with a yellow discoloration of the white part. The most common symptom is yellowing of the skin. There may also be other symptoms such as crying and restlessness, fever, or rapid and irregular breathing. Some babies might sleep longer than usual, have difficulty feeding, or experience issues with bowel movements, such as a significant decrease in stool frequency or a reduction in urine output. These could be accompanying symptoms of neonatal jaundice. Each baby presents differently with jaundice; more accompanying symptoms often indicate a more severe condition. If the jaundice is limited to skin discoloration without other significant symptoms, it may indicate an early stage of the condition. Generally, if the jaundice is pronounced, it is considered pathological jaundice, and it is advisable to go to the hospital. A pediatric specialist can conduct relevant examinations and decide if immediate intervention and treatment are necessary.
Does neonatal jaundice cause fever?
Fever in newborns with simple jaundice is relatively rare. If a newborn has jaundice accompanied by fever, it is important to be vigilant for the possibility of sepsis. Since the symptoms of sepsis in newborns are atypical and non-specific, it is essential to take this seriously. It is recommended that parents promptly take the child to the hospital for examination. A blood culture should be performed to determine if sepsis is present. If the jaundice is excessively high, active phototherapy may be necessary to reduce the bilirubin levels.
Does Kawasaki disease cause coughing?
Kawasaki disease has an unclear pathogenesis, primarily manifesting as systemic vasculitis, frequently affecting the coronary arteries. Clinically, it is characterized by fever, typically a high fever lasting seven to fourteen days, and is unresponsive to antibiotic treatment. Other symptoms include conjunctival congestion, cracked lips, diffuse oral congestion, and strawberry tongue. In the acute phase, there might be hard edema and erythema development, with polymorphous erythema and scarlatiniform rash typically on the trunk. Additionally, unilateral or bilateral cervical lymphadenopathy with tenderness can occur. Generally, coughing is rare and may be due to other infections like upper respiratory infections in children with weaker immunity.
