What formula should a child with diarrhea eat?
When a child experiences diarrhea, it indicates that there is an abnormality in their gastrointestinal function, and their ability to absorb nutrients is significantly weakened. If the child is fed ordinary formula, it might overburden their stomach and intestines, making digestion difficult and possibly exacerbating the diarrhea symptoms. Therefore, when a child has diarrhea, it is advisable to choose foods or formulas that are easy to digest. During periods of diarrhea, it is generally recommended for children to consume a special formula designed for infants with diarrhea. This formula is easier to absorb and helps in the digestion and absorption of nutrients, making it suitable for children with diarrhea.
Rickets symptoms
Rickets, also known as nutritional vitamin D deficiency rickets, is a chronic nutritional disease in children caused by inadequate vitamin D in their bodies, leading to disorders in calcium and phosphorus metabolism and characterized by changes in the growth plates. Its manifestation varies with different ages. In infants under six months, especially those under three months, symptoms often include increased nervous excitability, such as being easily irritable, restless, sweating, and shaking their heads due to scalp irritation. As the condition progresses in children under six months, the primary changes are seen in the skull; the edges of the anterior fontanelle are softer, and the skull is thinner. After six months, the softening of the skull disappears, but there can be ping-pong ball-like changes around the skull, leading to a box-shaped head from seven to eight months. Gradually, beading changes form, most notably around the 7th to 10th ribs. Around the age of one, children can develop a pigeon chest deformity, and in severe cases of rickets, a horizontal depression forms at the lower edge of the thoracic cage, known as the costal groove or Harrison's groove. Due to bone softening and muscle and joint laxity, when the child begins to stand and walk, the legs may become bow-legged or X-shaped, and in severe cases, can develop into 'K'-shaped leg deformities. Once the child starts to sit and stand, general ligament laxity can cause spinal deformities. Severe hypophosphatemia leads to muscle carbohydrate metabolism disorder, resulting in overall muscle laxity, decreased muscle tone, and subsequently reduced muscle strength.
Initial symptoms of hand, foot, and mouth disease
Hand, foot, and mouth disease is a contagious disease caused by viral infection, which is common in infants and toddlers, especially those under the age of three. The main symptoms include fever, accompanied by maculopapular rashes or vesicles on the hands, feet, mouth, and buttocks. Some initial symptoms are similar to having a cough, runny nose, headache, mouth pain, or sore throat. Sometimes there may be drooling; consequently, babies might drink less milk, and there can be nausea and vomiting. Additionally, some children may experience nausea and diarrhea along with other gastrointestinal symptoms. Another major sign is the presence of vesicles in the hands, feet, and mouth, or maculopapular rashes on the buttocks.
How to treat pectus carinatum?
Pectus carinatum, commonly known as pigeon chest, is a typical chest deformity characterized by a protruding sternum. There are various causes for pigeon chest, such as rickets due to vitamin D deficiency, and some hereditary metabolic diseases may also lead to bone development malformations like pigeon chest. If pigeon chest is caused by rickets, it is necessary to supplement adequate vitamin D, engage in appropriate outdoor activities, and receive sufficient exposure to ultraviolet light. Additionally, mild cases of pigeon chest can be treated with pediatric rehabilitation using active or passive methods for correction. In severe cases of chest deformity, surgical correction may be required. Generally, there are no effective solutions for hereditary diseases, and treatment mainly focuses on managing the symptoms accordingly. Therefore, if a child is suspected of having pigeon chest, it is advised to consult a specialist at a hospital to assess the child's condition and provide corresponding treatment.
Is Kawasaki disease serious?
Kawasaki disease is an etiologically unclear disease with a not well-understood pathogenesis. The principal pathological change involves inflammatory changes in the systemic blood vessels, which can affect the coronary arteries and lead to coronary artery aneurysms and dilation. Kawasaki disease is self-limiting, and most cases resolve well, with recurrences seen in 1-2% of cases. For patients without coronary artery lesions, comprehensive examinations are required 1 month, 3 months, 6 months, and 1-2 years after discharge, including physical examinations, electrocardiograms, and echocardiograms, mainly to assess the heart's condition. If not effectively treated, 15-20% may develop coronary artery aneurysms; such cases need semi-annual or annual medical check-ups. Coronary artery aneurysms often self-resolve within two years post-diagnosis, typically leaving functional abnormalities such as thickening of the vessel wall and reduced elasticity. Major artery aneurysms often do not disappear completely and can lead to thrombosis or narrowing of the vessel lumen. Kawasaki disease is one of the common causes of acquired heart disease in children; therefore, if Kawasaki disease is accompanied by severe coronary damage, it may heal well but could lead to heart disease. If it is not a severe case of Kawasaki disease, timely treatment can still result in a good recovery.
symptoms of pneumonia in children
Pneumonia in small children commonly occurs in infants and toddlers under two years old, often starting abruptly. It usually begins with symptoms of an upper respiratory infection several days before onset. The main clinical symptoms are as follows: First, there is fever, which can be irregular, remittent, or persistent; in newborns or severely malnourished children, the body temperature may not rise or may be below normal. Second, there is coughing, which is generally frequent; initially, it is a dry, irritating cough, but during the peak of the illness, the cough may subside, returning with phlegm during the recovery period. Third, shortness of breath arises, typically after fever and coughing; sometimes it is accompanied by general symptoms such as listlessness, reduced appetite, restlessness, mild diarrhea, or vomiting.
How does neonatal jaundice resolve quickly?
Neonatal jaundice is one of the common symptoms during the newborn period. It can be divided into physiological and pathological jaundice. Physiological jaundice typically appears in full-term infants two to three days after birth and peaks around the fourth to fifth day. It usually subsides around ten days and generally doesn't last more than two weeks. Physiological neonatal jaundice typically doesn't require intervention. If it is pathological jaundice, where the jaundice progresses quickly and is severe, it is important to consider whether hospital treatment is necessary. The quickest and most effective treatment for severe jaundice is phototherapy with blue light to reduce the bilirubin levels. Additionally, if there are pathological causes, such as infection or hemolysis, treatment should target these underlying causes. Even though phototherapy can reduce bilirubin levels, jaundice may rebound if the underlying issues are not promptly controlled. Therefore, treatment of pathological jaundice should focus on addressing the causes and symptomatic phototherapy.
Symptoms of sudden rash in infants
The symptoms of baby rash, a common febrile exanthematous disease in infants and toddlers, usually occur in children under three years old. The peak incidence is between six and seven months after birth. Typically, the child suddenly has a high fever without an obvious cause. The general body temperature is around 39 to 40 degrees Celsius. Besides a loss of appetite, the child generally remains in good spirits, though some may present with a mild fever, not exceeding 38 degrees Celsius. After three to five days of fever, the temperature suddenly drops, generally returning to normal within twenty-four hours. Once the fever subsides or as the temperature begins to decrease, a rash typically appears on the skin, usually rose-red maculopapular or macular rashes. A few children may show mild irritability, swollen lymph nodes, or symptoms of diarrhea and vomiting.
Does neonatal jaundice recede from the forehead first?
Neonatal jaundice is one of the most common phenomena in newborns, with about 80% of full-term infants visibly exhibiting jaundice. Typically, the development of jaundice begins in the facial area and gradually extends to the trunk and limbs. Its reduction follows the reverse pattern, generally receding from the limbs to the trunk and then slowly to the facial area. Usually, if the face no longer appears yellow, the jaundice has essentially subsided.
The function of the pneumonia vaccine
Pneumonia vaccines are generally aimed at preventing infections caused by Streptococcus pneumoniae. There are two common types of vaccines: the 23-valent polysaccharide vaccine, which is suitable for high-risk populations over two years old, and the 7-valent or 13-valent conjugate vaccines, which are mainly used for vaccinating infants under two years of age. Streptococcus pneumoniae is the most common and widespread bacterium causing pneumonia, and pneumonia caused by this bacterium is also the most prevalent worldwide. It is also the most significant pathogen in community-acquired pneumonia in children and a major cause of otitis media, meningitis, and bacteremia in children. The pneumonia vaccines mainly target common serotypes of Streptococcus pneumoniae, such as the 7-valent or 13-valent, designed to prevent infections from seven or thirteen serotypes, respectively, while the 23-valent vaccine aims to prevent infections from 23 serotypes. These pneumonia vaccines play a significant protective role in preventing infections caused by Streptococcus pneumoniae, however, they cannot prevent all cases of pneumonia.
