Multifocal Epstein-Barr Virus-Negative Posttransplantation Lymphoproliferative Disorder Treated With Reduction of Immunosuppression.

Posttransplantation lymphoproliferative disorder (PTLD) is associated with significant mortality in kidney transplant recipients. PTLD cases associated with poor prognostic factors that are refractory to reduction of immunosuppression generally require chemotherapy and immunotherapy. We present a patient with PTLD who achieved complete remission after reduction of immunosuppression alone despite having a poor prognosis.

Estimation of 24-hour urine protein quantity by the morning-urine protein/creatinine ratio.

Background: Many reports have described a correlation between the morning-urine protein /creatinine ratio (morning urine P/Cr) and the quantity of 24-h urine protein (Up), as well as regression formulas for Up with morning-urine P/Cr. However, there is no universal regression formula that can be used at all facilities. It is still controversial whether a qualitative calculation is required at outpatient clinics.

Fetal ultrasonography to prevent irreversible neurological sequelae of neonatal neuroblastoma.

An intra-abdominal mass was observed by fetal ultrasonography at 32 weeks of gestation. The baby was diagnosed as having neuroblastoma at the time of delivery at 39 weeks and its lower extremities were completely paralyzed. The chemotherapy after birth was quite effective to reduce the mass volume but neurological sequelae failed to improve.
