Glomerulonephritis Case Studies A 7-year-old boy was brought to his pediatrician because he had developed hematuria, which required hospitalization. Approximately 6 weeks before his admission, he had a severe sore throat but received no treatment for it. Subsequently, he did well except for complaints of mild lethargy and decreased appetite. Approximately 3 weeks before admission, he had a temperature of 101° F daily for 7 days. He complained of minimal bilateral back pain. Physical examination revealed a well-developed young boy with moderate bilateral costovertebral angle (CVA) tendemess. The remainder of the physical examination results were negative. His blood pressure was 140/100 mm Hg in both arms and legs. Studies
