AI Article Synopsis
- Forty-seven out of 150 long weaners (15 months old) died from acute renal disease after being introduced to a maize field crowded with Amaranthus species.
- Symptoms included sudden neurological issues like ataxia, swelling, and fluid accumulation in the abdomen and around the kidneys.
- Necropsy revealed severe kidney damage and bleeding, and while similar cases have been noted in other livestock in the Americas due to Amaranthus, South Africa has mainly linked these plants to nitrate and oxalate poisoning.
Article Abstract
Forty seven of 150, 15-month-old long weaners died of an acute renal disease syndrome following introduction into an old maize field with a heavy stand of Amaranthus spp. The clinical syndrome was characterised by sudden onset neurological disease with ataxia and recumbency. Subcutaneous oedema, ascites and perirenal oedema with urine odour were the major gross necropsy findings. Renal histopathology revealed marked coagulative renal tubular necrosis of the proximal and distal straight tubules with intertubular haemorrhage. Acute renal failure and perirenal oedema has been described in cattle, pigs, horses and sheep associated with the ingestion of A. hybridus L. and A. retroflexus L. This perirenal oedema syndrome has been widely reported in the Americas, while in South Africa intoxication with the amaranths has only previously been associated with nitrate and possibly oxalate poisoning in cattle.

Introduction: The aim of this study was to describe the clinical features and treatment responses of Rosai-Dorfman disease (RDD) and Erdheim-Chester disease (ECD) with kidney involvement.
Methods: We retrospectively analyzed patients with RDD and ECD with kidney involvement from 2005 to 2023, evaluating kidney function changes, as well as computed tomography (CT), and metabolic responses.
Results: The study included 4 patients with RDD and 44 with ECD, with median ages of 58 and 51 years, respectively.

Article Synopsis
- - Natural oak toxicity occurs when ruminants like cattle consume parts of oak trees, leading to severe health issues due to the breakdown of plant tannins by gut microbes and enzymes.
- - Symptoms of acute oak toxicity resemble those of renal disease, specifically acute tubular injury, which can be fatal.
- - A study of three beef calves in Colorado revealed significant kidney damage and unique microscopic features of oak-induced toxicity, highlighting previously undocumented effects on renal tissues and blood vessels.

Erdheim-Chester disease (ECD) is a rare tumor of histiocytic origin, characterized by foamy or lipid-laden histiocytes mixed or surrounded by fibrosis that infiltrate multiple organs. Misdiagnosis is common due to the diversity of clinical presentations. The present study reported a case of ECD with the involvements of bone, cardiac, aorta and retroperitoneum.

We characterized bovine viral diarrhea virus (BVDV)-related abortions in cattle and identified the species and subgenotypes in the state of Santa Catarina, southern Brazil. Our RT-PCR assay was positive for BVDV in 5 fetuses from different farms; however, 3 of the 5 fetuses were also PCR-positive for . In the 5 BVDV-positive fetuses, gross lesions included fetal mummification (1), hepatomegaly (1), subcutaneous edema (1), and perirenal edema (1).
