Two dogs were examined because of anorexia, lethargy, muscle tremors, weakness, and seizures that were associated with an acute onset of hypocalcemia. Both dogs had histories of chronic hypercalcemia. Examination of the parathyroid glands revealed infarction of focal parathyroid adenomas, with atrophy of the remaining parathyroid glands. It was concluded that the acute onset of hypocalcemia was caused by infarction of functional parathyroid adenomas that were previously responsible for the cause of persistent hypercalcemia. Infarction of a parathyroid adenoma should be included in a list of differential diagnoses of acute hypocalcemia in the dog, especially if hypercalcemia has been diagnosed previously.

Myonecrosis is an unusual sequelae to carbon monoxide poisoning with only 16 cases having been reported in the English-language literature. At the University of Illinois Hospital, we encountered a 25-year-old fire academy student who presented to our Emergency Department with a carboxyhemoglobin level of 16% following a training exercise in a smoke-filled room. The patient was not wearing a self-contained breathing apparatus and his duration of exposure was 7-8 min, by which time he had blacked out for about 1 min. Upon arrival, the patient was lethargic, with a moderate inhalation burn. The patient was treated with hyperbaric oxygen at 2 1/2 ATA. Following 90 min of hyperbaric oxygen, slight flexor compartment weakness, along with tenderness of the proximal lower extremities was noted. CPK was elevated to 65,998 (100% mm) with urine dipstick being positive for blood and only occasional rbc's seen in the urine sediment. The patient did well with forced diuresis and alkalinization of the urine. No oliguria was noted and the CPK fell to 893 five days later. This is the only case in the English-language literature who developed myonecrosis from carbon monoxide, despite hyperbaric oxygen treatment. We believe that this case demonstrates that hyperbaric oxygen cannot prevent the development of myonecrosis induced by carbon monoxide.

In a consecutive series of 100 neck explorations for primary hyperparathyroidism, 42 patients were 60 years of age or older; in this group of elderly patients the surgical cure rate was 100%. These patients were reviewed retrospectively by means of a structure interview. Twenty-one patients had had preoperative neuromuscular symptoms that ranged from coma to subjective muscular weakness. These patients had significantly-higher preoperative serum calcium and parathyroid hormone levels than did 21 patients without neuromuscular symptoms (P = 0.003 and P = 0.046, respectively). Most of the neuromuscular symptoms improved in the postoperative period. In particular, 15 of 17 patients with muscle weakness reported a significant improvement, while 14 of 15 patients who suffered from fatigue and lethargy reported an improvement. An improvement also occurred in the level of day-to-day function in eight patients. While surgery for primary hyperparathyroidism generally is undertaken for a specific indication, such as severe hypercalcaemia or renal stones, it appears from this study that neuromuscular symptoms also may improve, particularly in elderly patients.

Two weeks after daily topical application of hexachlorophene, a 4-week-old female kitten developed cardiovascular collapse, corneal ulcers, trembling, lethargy, and weakness. The kitten was euthanatized. At necropsy, the tissues appeared macroscopically normal; however, microscopic examination of tissue specimens indicated status spongiosis, astrocytosis, and microgliosis of the cerebral and cerebellar white matter and corticospinal tracts. Neuronal cell bodies forming the affected white matter were intact, indicating that demyelination may have been the cause of the lesions. The neurologic lesions were considered compatible with those of hexachlorophene-induced toxicosis.

A 4-year-old Airedale Terrier that had developed estrogen-induced aplastic anemia had a complete recovery after supportive treatment and weekly administrations of nandrolone decanoate. The anemia was induced iatrogenically by administration of estradiol cypionate (2 mg, IM each time) at 48- to 72-hour intervals. Clinical signs included lethargy, anorexia, and weakness; hemoglobin was 6.8 g/dl, PCV was 21%, and WBC was 1,500/dl. Supportive treatment included blood transfusions and administration of antibiotics, corticosteroids, and vitamins. Hematologic values returned to normal by day 81, and the dog has remained healthy for one year after treatment.

T-2 toxin at 0 or 15 mg/kg in 0.75 ml dimethyl sulfoxide was topically applied to 11- to 12-week-old specific-pathogen-free derived crossbred female pigs. Animals were killed on Days 1, 3, 7, or 14 after treatment. Clinical signs and morphologic changes in the skin and internal organs, as well as the residual concentrations of T-2 toxin and its metabolites in plasma, bile, urine, skin, and subcutaneous tissue, were examined. The T-2-treated pigs had signs of lethargy, anorexia, posterior weakness or paresis, and persistent fever. The skin at the site of application was red and swollen initially and progressively became dark red and then purple. By Day 7, at the margin of the exposed area, clefts had formed and were covered by serosanguinous exudate. By Day 14, the affected skin was focally separated from the underlying tissue and covered by a thick scab. The initial skin lesions were characterized as a spongiotic dermatitis and were located mainly in the dermal papillae and stratum germinativum of the epidermis. These lesions progressed to a locally extensive necrotizing dermatitis between Days 3 and 7 that was still evident at Day 14. Healing began on Day 7 and was more prominent on Day 14. Morphologic changes in the internal organs were minimal. They consisted of necrosis of single cells in the follicles of lymphoid tissues and in the exocrine pancreas.(ABSTRACT TRUNCATED AT 250 WORDS)

T-2 toxin at 0 (6 pigs) or 15 mg/kg (8 pigs) in 0.75 ml of dimethyl sulfoxide was topically applied to 9- to 10-week-old, male castrated, specific-pathogen-free derived pigs which were immunized subcutaneously with sheep red blood cells (SRBC) on Days 0 and 21. Whole blood and serum samples were taken periodically for clinical pathologic and immunologic evaluations. The pigs were observed daily and weighed weekly; their rectal temperatures were measured periodically. The T-2-treated pigs displayed anorexia, lethargy, posterior weakness and paresis, persistent high fever, and reduced body weight gain. Prominent neutrophilia, decreased serum glucose, albumin, and alkaline phosphatase activity, and increased serum globulin were seen in the T-2-treated group. The responses of enriched peripheral blood mononuclear cells to mitogens concanavalin A, phytohemagglutinin, and pokeweed mitogen of the T-2-treated group were significantly lower than those of the control group both at early (3 to 5 days) and late (20 to 28 days) postdosing intervals. No significant effects were noted in the hemagglutination titer to SRBC. Thus, in addition to the severe local dermal injury reported previously, topical exposure of swine to a sublethal dose of T-2 toxin, 15 mg/kg, can cause significant systemic effects on parameters such as body weight gain, rectal temperature, hematology, serum biochemistry, and cellular immune response.

A 7-year-old adult male ferret had progressive hair loss that was bilaterally symmetric. Also clinically evident were severe dehydration, polydipsia, muffled heart sounds, weak femoral pulses, hepatomegaly, lethargy, weakness, temporal muscular atrophy, dyspnea, and weakness. The blood profile of the ferret indicated profound leukopenia, eosinopenia, and high phosphorus, BUN, creatinine, and potassium concentrations, as well as high aspartate transaminase activity; the albumin concentration was low. The serum cortisol concentration was 8.1 micrograms/dl. Necropsy and histologic findings confirmed a diagnosis of hyperadrenocorticism, complicated by dilatative cardiomyopathy, chronic active hepatitis, and renal disease.

Two siblings with hyperornithinemia, hyperammonemia, and homocitrullinuria are reported. The clinical picture included protein intolerance, mental retardation, seizures, and stuporous episodes. One patient had cerebellar ataxia, myoclonus, convulsive seizure, and muscular weakness in both legs. Isolated liver mitochondria in the patient revealed that ornithine transport and citrulline synthesis were decreased, but urea cycle enzymes and ornithine aminotransferase were normal. Ornithine metabolism was decreased in cultured skin fibroblasts.
