Two pet rabbits were presented with an acute decrease in appetite and activity. Rabbit 1 showed severe hypothermia, bradycardia, arrhythmias, a heart murmur, dyspnea, occlusion of the nares with secretions, icterus, dehydration, and gaseous gastrointestinal dilation. The urine was dark yellow. Rabbit 2 was overweight, apathetic, and dehydrated; this animal presented with a heart murmur, gastric dilation, and intermittent nystagmus with dorsal strabismus in the right eye. Blood gas, electrolyte, hematology, plasma clinical biochemistry analysis, coagulation profile, plasma protein electrophoresis, urinalysis, and radiographic examinations were performed. The main shared findings were moderate thrombocytopenia, markedly decreased aspartate aminotransferase and alanine aminotransferase activities and fibrinogen concentrations, prolonged prothrombin and activated partial thromboplastin times, profoundly increased alkaline phosphatase and gamma-glutamyl transferase (GGT) activities, and high bile acid and bilirubin concentrations. Rabbit 1 also had respiratory acidosis, marked hypoglycemia, hyperphosphatemia, and a profoundly increased creatine kinase activity. Gastric dilation was observed on both radiographic exams. A low urinary pH of 5-6, marked bilirubinuria and proteinuria, and high urinary GGT levels were present in both patients. Marked icterus developed before death, which occurred within 22 and 30 hours post admission in rabbits 1 and 2, respectively. The necropsy of rabbit 1 showed a markedly accentuated hepatic lobular pattern, pulmonary hemorrhages, pericardial effusion with adhesions, peritoneal petechiae, and icteric and hemorrhagic abdominal fat. Histopathologic findings included hemorrhagic diathesis, severe centroacinar and midzonal hepatocellular necrosis, severe necrosuppurative bronchopneumonia, and moderate cardiomyocyte necrosis. A liver PCR assay was positive for Rabbit Hemorrhagic Disease Virus (RHDV) 2 (RHDV2) and negative for classic RHDV. This is the first description of the gross clinicopathologic abnormalities associated with naturally occurring RHDV2 infection in pet rabbits.

Quantum dots (QDs) are engineered nanoparticles (NPs) of semiconductor structure that possess unique optical and electronic properties and are widely used in biomedical applications; however, their risks are not entirely understood. This study investigated the tissue distribution and toxic effects of cadmium telluride quantum dots (CdTe-QDs) in male BALB/c mice for up to 1 week after single-dose intravenous injections. CdTe-QDs were detected in the blood, lung, heart, liver, spleen, kidney, testis and brain. Most CdTe-QDs accumulated in the liver, followed by the spleen and kidney. At high doses, exposure to CdTe-QDs resulted in mild dehydration, lethargy, ruffled fur, hunched posture, and body weight loss. Histological analysis of the tissues, upon highest dose exposures, revealed hepatic hemorrhage and necrotic areas in the spleen. The sera of mice treated with high doses of CdTe-QDs showed significant increases in alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin levels, as well as a reduction in albumin. CdTe-QD exposure also led to a reduced number of platelets and elevated total white blood cell counts, including monocytes and neutrophils, serum amyloid A, and several pro-inflammatory cytokines. These results demonstrated that the liver is the main target of CdTe-QDs and that exposure to CdTe-QDs leads to hepatic and splenic injury, as well as systemic effects, in mice. By contrast, cadmium chloride (CdCl2), at an equivalent concentration of cadmium, appeared to have a different pharmacokinetic pattern from that of CdTe-QDs, having minimal effects on the aforementioned parameters, suggesting that cadmium alone cannot fully explain the toxicity of CdTe-QDs.

A 54-year-old woman prepares dinner around 8:00 pm that includes mushrooms that she picked from her yard. The next morning, around 8:00 am, the woman (patient), her daughter, and son-in-law all develop abdominal cramps, violent vomiting, and diarrhea. They present to the emergency department and are admitted for dehydration and intractable vomiting with a presumed diagnosis of food poisoning. Twenty-four hours later, they appear well with stable vital signs and improved symptoms. Four hours later, 36 hours post-ingestion, the patient becomes lethargic. A venous blood gas reveals pH, 7.1; PCO2, 16 mmHg; and her AST was 3140 units/L with an ALT of 4260 units/L and an INR of 3.7.
