A moderate malignant hyperthermia developed in a Labrador Retriever anaesthetized with isoflurane for a femoral shaft fracture repair. Signs of malignant hyperthermia included progressive increases in PETCO2 and rectal temperature up to 39.8 degrees C, tachycardia, cyanosis, and elevated serum levels of potassium, inorganic phosphorus, AST, CK and alkaline phosphatase. Treatment initiated in the early recovery period consisted of hyperventilation with 100% oxygen, stomach lavage with iced water, body surface cooling, and intravenous administration of cold isotonic saline solution. Cooling was continued until the rectal temperature had dropped to 37.3 degrees C. After treatment the dog recovered uneventfully. Clinical signs, pathophysiology, therapy, prevention of malignant hyperthermia and its association with other disorders are discussed.

Nine- to ten-week-old, male castrated, specific pathogen-free derived pigs, weighing 34 to 42 kg, were exposed to a T-2 toxin aerosol (390 micrograms/liter, 1.5 microM mass median aerodynamic diameter) for a time period which allowed an amount equivalent to 8 mg/kg to be nebulized (six pigs). Control animals (five pigs) were exposed to an equivalent amount of the nebulized vehicle. Pigs were immunized subcutaneously with sheep red blood cells on Days 0 and 21. Whole blood and serum samples were taken periodically for clinical pathologic and immunologic studies. Pigs were closely observed, and daily rectal temperatures and weekly weights were measured. The T-2-treated pigs vomited and exhibited cyanosis, anorexia, lethargy, lateral recumbency, slightly elevated rectal temperature, and depressed body weight gain. The lymphocyte count decreased while the neutrophil count increased. The concentrations of total serum protein and hemoglobin declined. There was a marked increase in serum alkaline phosphatase activity on Day 1, followed by a marked and persistent decrease. Mitogen-induced (Con A, PHA, and PWM) blastogenic responses of peripheral blood mononuclear cells and hemagglutination titers to SRBC were also transiently decreased. Thus, inhalation exposure of pigs to a sublethal dose of T-2 toxin caused clinical signs of toxicity and adverse effects on clinical pathologic parameters and immune responses; however, most of these effects were short-lived. The changes described in our study resemble those reported in pigs given T-2 toxin by intravascular injection.

1. Endosulfan insecticide is a polychlorinated compound used for controlling a variety of insects; it is practically water-insoluble, but readily adheres to clay particles and persists in soil and water for several years. Its mode of action involves repetitive nerve-discharges positively correlated to increase in temperature. This compound is extremely toxic to most fish and can cause massive mortalities. In fish, it causes marked changes in Na and K concentrations, decrease in blood Ca(2+) and Mg levels and inhibits Na, K and Mg-dependent ATPase (in brain). 2. Bioaccumulation of endosulfan is reported for marine animals; however, freshwater animals (e.g., crayfish) accumulate it to some extent, but they lose the compound rapidly during depuration. Endosulfan is generally less toxic to aquatic invertebrates than fish. However, it causes decreases in adenylate energy charge, oxygen consumption, hemolymph amino acids, succinate dehydrogenase, heart-beat (mussel) and altered osmoregulation. 3. Generally, mammals are less susceptible to endosulfan's toxicity than aquatic animals. The majority of studies conducted on laboratory mammals can be summarized. (a) Neurotoxicity: male rats are more sensitive than females to endosulfan, which decreases brain and plasma acetylcholinesterase activity. Endosulfan I (a metabolite) causes a significant change in norepinephrine, 5-HT and GABA. (b) Renal toxicity: inhibition of MFOs activity was noticed in rats; other effects included changes in proximal convoluted tubules and necrosis of the tubular epithelium. (c) Hepatotoxicity: chemically-induced aminopyrine N-demethylase and aniline hydrolase were found in rat liver, and reduction in the glycogen level occurred. (d) Hematologic toxicity: endosulfan exposure resulted in a significant decrease in the level occurred. (d) Hematologic toxicity: endosulfan exposure resulted in a significant decrease in the erythrocyte glutathione reductase, hemoglobin amount, RBC number and mean corpuscular volume. 4. Respiratory toxicity: involved dyspnea, acute emphysema, cyanosis and hemorrhages in teh interalveolar portions of rat's lungs. 5. Biochemical: in rats, endosulfan caused increased glucose-6-phosphate dehydrogenase activity, blood glucose level, phospholipid contents of the microsomal and surfactant system, and profoundly induced the activity of alcohol dehydrogenase and cytosolic glutathione S-transferases. It also decreased significantly Na+, K+ and Mg(2+) ATPases, plasma calcium level and alkaline phosphatase in the intestinal epithelium. 6. Immunologic toxicity: rat serum antibody titer to tetanus toxin, IgG, IgM and gammaglobulins were significantly reduced. 7. Reproductive toxicity: degenerative changes in the seminiferous epithelium, induction of the rate-limiting enzyme in testosterone production (3beta-hydroxysteroid transferase and 17 beta-hydroxysteroid transferase), histological changes in reproductive organs, testicular atrophy and the occurrence of ovarian cysts were noticed in rat. Reduction in the weight of secondary sex organ was also observed.(ABSTRACT TRUNCATED AT 400 WORDS)

Five weeks after a four-day visit to Malta, a 39-year old white male German national developed septic temperatures of up to 40 degrees C, progressive jaundice and a pronounced hepatosplenomegaly. The initial examination showed a very sick, somnolent patient with jaundice, cyanosis, tachypnea and a markedly enlarged liver on both physical examination and sonography. The laboratory evaluation revealed a moderate leukocytosis, markedly accelerated ESR, poor liver function with strongly elevated gamma-GT and alkaline phosphatase levels. Primary antibiotic therapy consisted of doxycycline. Ultrasound examination of the liver four days after admission revealed multiple hypodense abscesses. On the sixth day after admission, gram-negative rods were first isolated from blood cultures; antibiotic therapy was switched to ofloxacin (2 x 400 mg/day) and amoxycillin (3 x 2 g/day) after sensitivity testing. As a result of treatment with this combination of antibiotics, the patient was free of fever 10 days after hospitalization; on the same day yersinia enterocolitica was isolated from the first blood cultures taken on admission. The diagnosis of non-enteric forms of yersinia infection can prove very difficult, especially if the serology is not clear cut and there are no immunological complications. A presentation including intermittent fever, moderate leukocytosis, strongly accelerated ESR and multiple hypodense abscesses in the liver should lead one to consider a non-enteric type of yersinia infection. Hepatic abscesses usually occur in patients who have an iron overload.

Hypophosphatasia is a rare inborn disease of metabolism. This paper reviewed its pathogenesis, forms, clinical manifestations, differential diagnosis,treatment and prognosis. Here a case of neonatal hypophosphatasia is reported. This baby was female (30 minutes old). Prenatal ultrasound showed disproportionate biparietal diameter and long bones of limbs in the baby. After birth, she presented with obvious craniomalacia, respiratory distress and cyanosis. Serum alkaline phosphatase level was significantly reduced. Both X-ray and autopsy showed extremely insufficient skeletal mineralization. Four days later she died of respiratory failure.
