The complex biologic investigation of thyphoid fever is dictated by the necessity of instituting a pathogenetic therapy, especially in the toxic and complex forms. Performing 178 fuctional-metabolic tests in 50 cases of typhoid fever (of which 10 severe and complicated forms), the authors established the prognostic value energy deficiency (approximately P), lactate, alkaline reserve and GPT. Azotemia is only characteristic in the forms with renal involvement, and the other transaminases may be positive even whe the liver is not enlarged. In one case of repeated digestive hemorrhage no evidence could be found of the mechanism of consumption coagulopathy.

Urethral obstruction induced in adult male cats caused clinical signs identical with those observed in naturally occurring disease. Central nervous system depression, anorexia, dehydration, vomiting, muscle weakness, and hypothermia occurred. Weight loss (due to water loss and catabolism), metabolic acidosis, mild hyponatremia, hyperkalemia, hypermagnesemia, hypocalcemia, hyperphosphatemia, hyperglycemia, azotemia, and hyperproteinemia were also observed. Serum amylase, alkaline phosphatase, and alanine aminotransferase activities were normal. Ten of 13 cats (group 1), with 72 hours' induced obstruction but not treated with parenteral fluids, died either before the obstruction was relieved or within 8 days afterward. Eight cats (group 2) with induced obstruction for 49 to 98 hours developed severe clinical and biochemical alterations. Treatment with a multiple-electrolyte solution, in addition to relief of urethral obstruction, resulted in favorable clinical and biochemical responses. These cats survived and were clinically healthy at 9 to 10 days after relief of obstruction. It was concluded that use of a multiple-electrolyte solution to correct acidosis, restore circulatory volume, and enhance renal excretion of potassium was effective supportive therapy after urethral obstruction was removed.

The systemic administration of interleukin-2 (IL-2) can lead to significant antitumor responses in some patients with metastatic cancer in whom standard therapy has failed. A limitation of this immunotherapy is the toxicity associated with IL-2 infusion. To assess toxicity, we determined aspartate aminotransferase (AST; EC 2.6.1.1), alanine aminotransferase (ALT; EC 2.6.1.2), gamma-glutamyltransferase (GGT; EC 2.3.2.2), lactate dehydrogenase (LD; EC 1.1.1.27), alkaline phosphatase (ALP; EC 3.1.3.1), creatine kinase (CK; EC 2.7.3.2), total bilirubin (TBI), direct bilirubin (DBI), creatinine, urea nitrogen, and C-reactive protein in serum from 21 patients before and during five consecutive days of IL-2 treatment. Ten patients were followed for an additional five days after the end of IL-2 therapy. The IL-2 infusion caused liver toxicity and prerenal azotemia, as evidenced by significant increases (P less than 0.05) of all analytes except CK by day 1. There was a progressive increase in the results (except CK) for these tests until IL-2 treatment was stopped. Seven tests related to liver function (AST, ALT, GGT, LD, ALP, DBI, and TBI) showed increases, but the test results indicated significant improvement and moved toward the baseline value five days after the end of IL-2 therapy. Concentrations of creatinine and urea nitrogen in serum were normal three days after the cessation of IL-2 therapy.

An open, randomized, controlled study including 57 patients with acute cerebral infarct was performed. All the patients, followed and controlled by the same examiner, received, in the first ten days, 24 mg/die i.v. of dexamethasone. 28 patients were also treated with mesoglycan (150 mg/die i.m. for five days and 144 mg/die per os for a further twenty-five days). The differences between the basal and final scores in the mesoglycan group and in the controls were not statistically significant as analysed by the Mann-Whitney U test. The mesoglycan influenced only slightly the laboratory values (PT, PTT, alkaline phosphatase, GOT, GPT, cholesterol and triglycerides, fibrinogen, blood glucose, azotemia and creatinine) performed before the beginning of the treatment, as their changes after thirty days of therapy were in the normal range. The mesoglycan was very well tolerated and no side-effects were observed during the treatment.

The medical records of 14 hyperthyroid cats with thyroid carcinoma were analyzed retrospectively regarding historical, physical, laboratory, and thyroid scintiscan findings, treatment, and treatment outcome. Breed predilection was not detected, and older castrated male cats were most commonly affected. The most common clinical signs detected by owners were weight loss, polydipsia, polyuria, polyphagia, hyperactivity, and anorexia. Physical examination findings included tachycardia, palpable cervical mass, hyperactivity, cardiac murmur, and abnormal coat. Common abnormal laboratory findings were high serum thyroxine and triiodo-thyronine concentrations and high serum alanine transaminase, alkaline phosphatase, and aspartate transaminase activities. Azotemia, hyperphosphatemia, and hyperglycemia were noticed less frequently. The most common thyroid scintiscan findings were multiple nodular areas of high radionuclide uptake in the cervical region, thoracic inlet, and cranial mediastinum. The most common morphologic diagnosis was mixed compact and follicular carcinoma, with follicular and papillary carcinomas being less common. Most cats responded well to treatment of the thyroid tumor, with rapid resolution of the historical and physical examination findings. The most common necropsy findings were local tumor invasion, regional lymph node metastases, cardiomyopathy, and interstitial nephritis.

Erythema multiforme major and disseminated intravascular coagulation developed in a dog 24 hours after exposure to a d-limonene-based insecticidal dip. Clinical signs included severe lethargy and weakness, ulceration of the oral mucosa, and erythematous serpiginous, annular, and arciform lesions on the head, trunk, and limbs. Clinicopathologic abnormalities included leukocytosis with neutrophilia, normocytic normochromic anemia, thrombocytopenia, prolongation of prothrombin and partial thromboplastin times, increased fibrin degradation products, hypoproteinemia, hyponatremia, hypochloremia, azotemia, high serum alanine aminotransferase and alkaline phosphatase activities, and high serum bilirubin concentration. Despite intensive supportive care, the dog developed severe intrathoracic and abdominal hemorrhage and died. Necropsy revealed severe diffuse epidermal necrosis and widespread hemorrhage within organs. Insecticidal dips containing d-limonene have the potential to induce various toxic effects, including, possibly, erythema multiforme major, and should be used cautiously.

This is the first confirmed report of exertional rhabdomyolysis in a non-human primate. The monkey was singly housed and presented with anorexia and reluctance to move. There was no external evidence of trauma. Clinicopathologic findings included mild azotemia, marked elevation in serum creatine phosphokinase (CPK), alanine aminotransferase, aspartate aminotransferase, and myoglobinuria. Two days post-incident, the peripheral skeletal muscle had marked multifocal myonecrosis and fibrillar disruption without an inflammatory reaction. Treatment included diuresis and pain relief, and urinary output was monitored. The monkey recovered over the next two weeks. The major significance of skeletal muscle damage is the potential of released myoglobin to cause acute renal failure in the presence of other co-factors such as hypovolemia, acidosis, or ischemia. CPK levels can be highly variable and are inconsistent with the degree of muscle damage; however, CPK is thought to be the most sensitive enzyme marker for muscle necrosis. Because of the potential life-threatening sequelae, exertional rhabdomyolysis should be included as a differential diagnosis when similar clinical and pathological signs are observed.

The prolonged use of CNI has been associated with nephrotoxicity. MMF is a new immunosuppressive agent. In the present study, the consequences of introducing MMF and reduction of CNI in liver-transplant children were analysed. The present study included eight pediatric liver-transplant patients who had transplantation at least 5 yr previously, had stable graft function and had renal dysfunction as a probable side-effect of CNI therapy. CNI was replaced with MMF in all patients and serum creatinine, uric acid concentration, azotemia and creatinine clearance before and 6 months after study entry were measured. The patients were monitored closely for side-effects of MMF as well as graft function. Six months after study entry serum creatinine, uric acid concentration, azotemia and creatinine clearance improved in all the patients at the last follow-up. The aspartate aminotransferase and alanine aminotransferase concentrations were stable during the study period and did not observe any serum bilirubin increased as well. No side-effects were reported in patients on MMF. Only one patient reported temporary pruritus and nausea. The results indicate that renal dysfunction significantly improved when MMF therapy is started and CNI reduced. Furthermore present data suggest that the risk of acute allograft rejection is very low when the CNI desired reduction is achieved in not too short time and absolutely when the MPA levels are strictly monitored.

We report a case of a 26-year-old White woman with a history of anorexia nervosa who developed severe liver damage and multiorgan dysfunction. At admission to our medical unit, her body mass index (BMI) was 10.8. Biochemical evaluation showed a marked increase in serum levels of aspartate aminotransferases (AST = 9,980 IU/L), alanine aminotransferase (ALT = 3,930 IU/L), amylase (1,002 IU/L), lipase (1,437 IU/L), creatine phosphokinase (CPK; 783 IU/L), and lactate dehydrogenase (LDH = 6,830 IU/L). Glomerular filtration rate was reduced (35 ml/min), reflecting dehydration and prerenal azotemia. No other cause of acute liver damage except malnutrition was evidenced. Hydration and nutritional support were the unique medical treatment. A rapid recovery occurred in few days and all laboratory data were normal at discharge after a 37-day hospitalization.

A 2-year-old, male, red-necked (Bennett's) wallaby (Macropus rufogriseus) from a zoological facility was presented for peracute onset of severe depression, unresponsiveness, ataxia, and loose feces. Serum biochemical abnormalities included azotemia, hypoalbuminemia, increased alanine aminotransferase activity, hyperbilirubinemia, hyperphosphatemia, and hyperkalemia, consistent with multi-organ system failure. Severe thrombocytopenia suggested possible disseminated intravascular coagulation. Peripheral blood smear examination revealed numerous ovoid, protozoal inclusions within monocytes and occasionally within neutrophils. Despite aggressive supportive therapy, the patent died within 5 hours of presentation. Gross necropsy and histopathologic findings included severe multifocal necrotizing lesions in multiple organs. Numerous intralesional protozoal organisms were observed and were identified as Toxoplasma gondii by immunohistochemistry. Macropods (wallabies and kangaroos) are known to be highly susceptible to toxoplasmosis, with high mortality rates; diagnosis most often is obtained at necropsy. Detection of protozoal organisms in peripheral blood leukocytes is reported rarely and has not been documented previously in a macropod. Parasitemia in this case was attributed to severe, disseminated disease. Careful examination of peripheral blood smears in macropods suspected of toxoplasmosis may be warranted.
