AI Article Synopsis
- A calcified amorphous tumor (CAT) is a non-cancerous growth in the heart, often linked to mitral annular calcification (MAC), especially in patients with end-stage renal disease (ESRD).
- A case is presented of a 43-year-old man with normal kidney function who was unexpectedly found to have a CAT during an echocardiogram, revealing a mass near the calcified mitral annulus.
- The diagnosis was confirmed through surgery and pathology, raising questions about the causes and treatment of CAT, particularly since it's rarely seen in patients without kidney issues.
Article Abstract
A calcified amorphous tumor (CAT) of the heart is a non-neoplastic mass, characterized by nodules of calcium on a background of amorphous fibrinous material. Mitral annular calcification (MAC) is one of the conditions most frequently associated with CAT. Most MAC-related CAT cases are reported in end-stage renal disease (ESRD) patients. This report is a description of a patient with normal renal function who was incidentally diagnosed with a CAT arising from MAC. An asymptomatic 43-year-old man with normal renal function underwent echocardiography. The echocardiography results revealed a highly mobile hyperechoic mass attached to the atrial side of the mitral annulus superimposed on a heavily calcified mitral annulus. Cardiac surgery and histopathological evaluation confirmed a diagnosis of MAC-related CAT. While MAC-related CAT is usually associated with ESRD patients, the precise etiology and management strategy of this benign tumor remain unclear. The rare incidence of this tumor in patients with normal renal function highlights the importance of further research of the pathology of this uncommon condition.

Introduction: Lupus nephritis (LN) is one of the most frequent and serious organic manifestations of systemic lupus erythematosus (SLE). Autophagy, a new form of programmed cell death, has been implicated in a variety of renal diseases, but the relationship between autophagy and LN remains unelucidated.
Methods: We analyzed differentially expressed genes (DEGs) in kidney tissues from 14 LN patients and 7 normal controls using the GSE112943 dataset.
Assessment of the interobserver and the intraobserver reproducibility for the detection of renal cortical defects in adults and children using [99mTc]Tc-MAG3.

Background: One can assess cortical defects on the early images of [99mTc]Tc-MAG3 renography. We aimed to assess interobserver and intraobserver reproducibility for detecting renal cortical defects using [99mTc]Tc-MAG3 for adults and children; identify causes for poor inter- and intraobserver reproducibility and to assess the effect of the kidney to background ratio (KTBR) on reproducibility.
Methods: One hundred adult and 200 pediatric renograms were included.

Introduction: Electrical injuries (EIs) represent a significant clinical challenge due to their complex pathophysiology and variable presentation, ranging from minor burns to severe internal organ damage. Despite their prevalence in both; domestic and occupational settings, there remains a rareness of systematic guidelines and comprehensive literature to aid clinicians in effectively managing these injuries. Understanding these factors is crucial for developing protocols that can mitigate the risk of delayed complications, such as cardiac arrhythmias, in patients who initially appear stable.

Because acute kidney injuries (AKI) are one of the critical health problems worldwide, studies on the risk factors, mechanisms, and treatment strategies seem necessary. Glycerol (GLY), known to induce cell necrosis via myoglobin accumulation in renal tubules, is widely used as an AKI model. This study aimed to evaluate the protective effects of gallic acid (GA) against GLY-induced AKI.

A supernumerary kidney is a rare birth defect where an extra kidney is present. This extra kidney has its own separate outer covering, blood supply, and collection system. Normally, percutaneous nephrolithotomy (PCNL) is the treatment of choice for large kidney stones, but its ideal use for supernumerary kidneys is unknown.
