This report describes the clinical and pathological findings in a case of acute zinc poisoning in a young dog. The puppy suffered four days of progressively more severe vomiting and diarrhoea. Jaundice and pale mucous membranes, severe haematemesis and haemoglobinuria were other findings. Despite intensive therapy, the dog died a few hours after hospitalisation. Postmortem examination revealed a metallic foreign body in the stomach, catarrhal gastritis, hepatomegaly and enlarged, dark kidneys. Histology showed hepatic centrilobular vacuolar degeneration, haemoglobinuric nephrosis with early tubular necrosis, haemosiderosis and extramedullary haematopoiesis, as well as neuronal damage. The foreign body was mainly composed of zinc. Plasma zinc values were markedly raised (34.5 microg/ml; normal range 0.8 to 1.0 microg/ml). Pathophysiological mechanisms of zinc poisoning are discussed.

Envenomation by a spotted black snake (Pseudechis guttatus), following multiple bites on the buccal mucosa of a captive maned wolf (Chrysocyon brachyurus), caused the animal's collapse, hemolysis, rhabdomyolysis, local tissue necrosis, hepatic and renal failure, and subsequent death. The wolf died despite intensive supportive care including antivenom administration, fluid support, and a blood transfusion. Gross necropsy findings included myocardial and intestinal hemorrhage, pulmonary congestion, hepatomegaly, and splenomegaly. Microscopic examination of formalin-fixed tissues demonstrated pulmonary and abdominal visceral hemorrhage, acute nephrosis with casts, multifocal hepatic necrosis, and splenic congestion.

A 38-year-old male was admitted with fever, progressive jaundice, cervical lymphadenopathy, hepatomegaly and acute oliguric renal failure. Epstein-Barr virus (EBV) infection was diagnosed by detection of EBV-DNA in plasma and confirmed by EBV seroconversion. Kidney biopsy revealed acute tubular necrosis and abundant casts, consisting of bilirubin pigment. With conservative treatment, the patient fully recovered from cholemic nephrosis, an uncommon condition, not described after EBV infection before.

A wide spectrum of genetic causes may lead to nonimmune hydrops fetalis (NIHF), and a thorough phenotypic and genetic evaluation are essential to determine the underlying etiology, optimally manage these pregnancies, and inform discussions about anticipated prognosis. In this review, we outline the known genetic etiologies of NIHF by fetal organ system affected, and provide a systematic approach to the evaluation of NIHF. Some of the underlying genetic disorders are associated with characteristic phenotypic features that may be seen on prenatal ultrasound, such as hepatomegaly with lysosomal storage disorders, hyperechoic kidneys with congenital nephrosis, or pulmonary valve stenosis with RASopathies. However, this is not always the case, and the approach to evaluation must include prenatal ultrasound findings as well as genetic testing and many other factors. Genetic testing that has been utilized for NIHF ranges from standard chromosomal microarray or karyotype to gene panels and broad approaches such as whole exome sequencing. Family and obstetric history, as well as pathology examination, can yield additional clues that are helpful in establishing a diagnosis. A systematic approach to evaluation can guide a more targeted approach to genetic evaluation, diagnosis, and management of NIHF.
