This can be kind of common in kids, so let's not jump to conclusions and assume something is necessarily wrong. In kids, these murmurs are often innocent, meaning there’s no real issue with ... | During a well-child examination of a 4-year-old girl, the most likely type of heart murmur that would suggest a benign condition is a Still's murmur. This type of murmur is common in young children, typically presenting between the ages of 2 and 6. It is characterized by a musical or vibratory quality and is usually he... |

They are looking pale, have a fever, and their spleen is swollen. This is worrisome because it could be a sign of several different things. Pallor makes me think of anemia. Fever? Well, that could mean an infection, which isn’t uncommon with a history of heart issu... | In the scenario you've described, the most unnecessary investigation to directly arrive at a diagnosis would be liver function tests. Given the child's presentation of pallor, fever, and splenomegaly, the more pressing concerns are likely related to anemia, infection, or hematological issues, connected with their rheum... |
