| Acute focal bacterial nephritis(AFBN) is an unusual form of localized renal infection, which has various imaging findings and should be distinguished from abscess or other renal masses. Clinical symptoms are similar to other urinary tract infections but the diagnosis needs a CT or sonographic confirmation. Treatment, which is nonoperative, consists of intensive antibiotic therapy. We report three cases of AFBN... |
| Individuals with Down syndrome have a high incidence of hematologic diseases such as transient myeloproliferative disorder(TMD) & acute leukemia. Because it is difficult to distinguish TMD from acute myeloblastic leukemia, the diagnosis in neonate, who have Down syndrome, should be made with extreme caution. TMD usually undergoes spontaneous remission within a few months, but acute leukemia can develope after remission... |
