To study the overt toxicosis of intraperitoneally (IP)-administered single doses of cholecalciferol (D3), groups of male CF-1 mice (N = 12) were given graded doses of D3 in corn oil and observed for 21 days. There was a 2- to 4-day onset of signs, including ocular squinting, reluctance to move, lethargy, weakness, anorexia, hunched posture, rough haircoat, and dehydration. This was followed by tremors, coma, and death (large doses) or gradual recovery. Deaths occurred 3 days (larger doses) to 21 days after D3 injection. The linear regression of mortality probits on log10 dose was Y = 7.332X-10.653. The median lethal dose (LD50) of D3 and 95% confidence limits were 135.4 mg/kg (112.2-157.4 mg/kg). To screen potential antidotes against acute D3 toxicosis, groups of mice (N = 12) were given subcutaneous (SC) injections of various substances beginning 2 days after IP injection of a large dose of D3 (300 mg/kg). Substances were given once or twice daily in constant volumes of saline solution (66.8 ml/kg) for 7 days. Two control groups were given D3 but no treatment. They both had 91.7% mortality; their mean (+/- SD) survival time (MST: censored to 21 days observation) was 6.8 +/- 4.7 days and 10.3 +/- 7.0 days. Mortality and MST were not affected significantly (P greater than 0.05) by once-daily injection of saline solution, saline containing dexamethasone (DEX), or saline containing the following substances with or without DEX: ascorbate; citrate; dimercaptosuccinic acid; oxytetracycline; ZnSO4; or MgCl2.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-six, ten-week-old mink were infected by force feeding by pipette 2 ml of a tissue suspension containing a Wisconsin strain of mink enteritis virus. Four days later, diarrhea and partial or complete loss of appetite developed simultaneously in all of the animals. Squinting and occasional vomiting were also observed. By the sixth day after inoculation, all of the mink were anorectic and weak. Anorexia persisted for 48 to 96 hours. Diarrhea and vomiting continued until the eighth to ninth day after exposure. For the first two days after the appearance of diarrhea, the feces contained large quantities of mucus and intestinal casts were seen frequently in the droppings. Thereafter, the feces consisted mostly of yellowish green, watery fluid and contained no casts. Some of the animals died on the eighth day after infection. Those which survived were severely dehydrated and debilitated, but resumed eating and achieved complete clinical recovery within the next five to six days.Leukopenia, i.e., total leukocyte count of less than 5,000 cells per mm(3) of blood, was found in seven of nine mink examined during the height of the disease. Leukopenic animals were deficient in both lymphocytes and neutrophils.

A 10-year-old boy with unilateral ophthalmoplegia, ptosis, and proptosis underwent diagnostic examination. Symptoms of headache, nausea, dyspnea, fatigue, weakness, and loss of appetite began 14 days after the onset of ocular manifestations and 7 days before he was examined. Complete blood count showed an increased white blood cell count with 64% blast cells, anemia, and thrombocytopenia. The patient was transferred to a pediatric hematology unit, where he underwent bone marrow aspiration biopsy. Bilateral ocular inflammatory findings and left-sided mild proptosis became evident. He was diagnosed as having B-cell non-Hodgkin lymphoma infiltrating the bilateral cavernous and sphenoid sinuses.

An 11-year-old spayed female domestic shorthair cat was evaluated for anorexia, lethargy and weight loss of 6 days' duration. Bilateral mydriasis, absent menace response, slow-to-absent pupillary light reflexes, bilateral retinal detachment, intermittent horizontal nystagmus, intermittent ventral strabismus and systemic hypertension were present. Biochemical analysis revealed severe hyponatremia, severe hypochloremia and mild hypokalemia. Multifocal central nervous system disease was suspected based on optic, trigeminal sensory (ophthalmic branch), vestibulocochlear and possible oculomotor nerve dysfunction. Thoracic radiographs showed mild cardiomegaly without evidence of congestive heart failure. Ultrasound revealed mild pleural and peritoneal effusion. A cause of the severe hyponatremia was not identified, and it persisted despite fluid therapy. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) was suspected as the cause of hyponatremia. Humane euthanasia was elected owing to continued clinical decline. Serum hyposmolality, urine hyperosmolality, natriuresis and lack of confirmed renal, thyroid and pulmonary disease aided in the presumed diagnosis of SIADH. Post-mortem histopathology of the brain revealed degeneration of the hypothalamus and optic tracts, along with a prominent fluid-filled craniopharyngeal duct (putative Rathke's cleft cyst) separating the pars distalis and the pars intermedius. The hypothalamic degeneration, possibly secondary to a Rathke's cleft cyst, was hypothesized to be the cause of presumptive SIADH in the patient. Although rare in occurrence, Rathke's cleft cyst should be included as a differential diagnosis in dogs and cats with signs of pituitary dysfunction.
