Thirteen years after kidney donation, a 70-year-old man was referred to a nephrologist because of proteinuria. The serum creatinine, albumin, and urinary protein levels were 2.39 mg/dL, 3.0 g/dL, and 6.72 g/gCr, respectively. ⋯ However, 11 months after the kidney biopsy, hemodialysis was required. The present case constitutes an important teaching point, as glomerular disease can occur in living donors and require careful and long-term medical checkup examinations.

Cardiomyopathy with an LMNA Genetic Variant Affecting Three Consecutive Generations: A Case Series.
We report the case of a family afflicted with cardiac laminopathy who showed atrial fibrillation (AF) and complete atrioventricular block across three generations. Implantable cardioverter defibrillators (ICDs) implantation, or cardiac resynchronization therapy (CRT) were delivered to the three patients (proband; 61 years old, proband's mother: 84 years old, and proband's daughter; 38 years old) to prevent sudden cardiac death or suppress heart failure progression. A novel frameshift mutation (LMNA Exon 9: c.1550dupA;p. N518Efs*34) was found in all three cases through genetic testing, and this mutation may potentially result in the relatively late appearance of a phenotype of left ventricular systolic dysfunction.

Objective Although magnetic resonance imaging (MRI) is the gold standard for evaluating abnormal myocardial fibrosis and extracellular volume (ECV) of the left ventricular myocardium (LVM), a similar evaluation has recently become possible using computed tomography (CT). In this study, we investigated the diagnostic accuracy of a new 256-row multidetector CT with a low tube-voltage single energy scan and deep-learning-image reconstruction (DLIR) in detecting abnormal late enhancement (LE) in LVM. Methods We evaluated the diagnostic performance of CT for detecting LE in LVM and compared the results with those of MRI as a reference. ⋯ These findings were extremely strongly correlated, with a correlation coefficient of 0.87 (p<0.0001). The effective radiation dose on late-phase scanning was 2.4±0.9 mSv. Conclusion The diagnostic performance of 256-row multislice CT with a low tube voltage and DLIR for detecting LE and measuring ECV in LVM is credible.
