Pancreatic abscess was diagnosed by exploratory celiotomy in 6 dogs. The most common clinical signs included acute onset of lethargy (n = 5), anorexia (n = 6), vomiting (n = 5), and diarrhea (n = 2). Physical examination revealed pain response to abdominal palpation (n = 5), depression (n = 5), icterus (n = 3), fever (n = 3), and cranial abdominal mass (n = 2). Consistent preoperative clinicopathologic abnormalities included leukocytosis with left shift, observance of toxic neutrophils on the blood smear, hyperlipasemia, hyperamylasemia, hyperbilirubinemia, and increased serum alkaline phosphatase activity. In 5 of 6 dogs, abdominal radiography revealed increased soft tissue density in the cranial portion of the abdomen. Ultrasonography performed on 4 dogs confirmed pancreatic mass. In all dogs, exploratory celiotomy revealed a cavitary pancreatic mass that contained sterile, mucopurulent material. Histopathologic diagnoses included acute necrotizing or chronic-active pancreatitis and steatitis. Two dogs were euthanatized at the time of diagnosis, and the remaining 4 were treated by use of pancreatic debridement(s), open abdominal drainage, and intensive administration of fluids and antibiotics. One dog was euthanatized 4 days after surgery, because of progressive pancreatic abscessation. Three dogs recovered and were discharged.

Diarrhea, intestinal blood loss, anemia, and lethargy were predominant clinical findings in 12 dogs with disseminated histoplasmosis. Young dogs were affected most commonly, with 6 dogs being 1 to 3 years old. A diagnosis of disseminated histoplasmosis was established on the basis of histologic or cytologic detection of Histoplasma organisms in intestinal or rectal mucosa in 7 dogs, in circulating leukocytes in 5 dogs, in bone marrow in 3 dogs, and in multiple tissues at necropsy in 1 dog (4 dogs had Histoplasma organisms detected in greater than 1 site). Anemia was detected in 10 dogs (PCV less than 20% in 3 dogs), and the anemia was inadequately regenerative or nonregenerative in 7. Hypoalbuminemia was detected in 9 dogs, and serum albumin concentrations were low (less than 1.0 g/dl) in 4 of the 9 dogs. Of 5 dogs treated with ketoconazole, 2 were in remission for greater than or equal to 1 year. Corticosteroid therapy may have exacerbated the disease in 4 dogs. Histoplasma infection of multiple organs was detected in 5 necropsied dogs.

Overall, acyclovir is a remarkably safe drug considering its potent antiviral effect. The most frequent reactions with short-term use of oral acyclovir are nausea and vomiting and with 6 months' use headache, diarrhea, nausea, and vomiting. These symptoms are also seen frequently with placebos. The most frequent adverse reaction to intravenous use has been inflammation and phlebitis at the injection site. The two most important serious adverse effects are (1) encephalopathic changes with abnormal electroencephalograms and lethargy, tremors, confusion, and seizures and (2) renal precipitation of the drug because of a rapid bolus of drug administered parenterally. Safety of acyclovir for use during pregnancy and in neonates and young children has not been established.

A retrospective chart review was conducted at two regional poison centers to determine the clinical outcome of boric acid ingestions and to assess the relationship between serum boric acid levels and clinical presentation. A total of 784 cases were studied; all but 2 were acute ingestions. No patients developed severe manifestations of toxicity, and 88.3% were entirely asymptomatic. The most common symptoms were vomiting, abdominal pain, and diarrhea. Lethargy, headache, lightheadedness, and atypical rash were seen less frequently. Boric acid levels were obtained in 51 patients and ranged from 0 to 340 micrograms/mL. Blood levels were 70 micrograms/mL or more in 7 patients; 4 remained asymptomatic, whereas the other 3 had nausea or vomiting. Dialysis was performed in 4 of these 7 patients, only 1 of whom had symptoms (vomiting). On the basis of data from 9 patients, the mean half-life of boric acid was determined to be 13.4 hours (range, 4.0 to 27.8). Hemodialysis in 3 patients significantly shortened the half-life compared with pre- and postdialysis half-lives. Our results suggest that acute boric acid ingestions produce minimal or no toxicity and that aggressive treatment is not necessary in most patients.

The case of a 3-week-old male infant is described. After receiving an iatrogenic overdose of metoclopramide (1.0 mg/kg every six hours) throughout a 36-hour period for the treatment of suspected gastroesophageal reflux, he became cyanotic, lethargic, and irritable, he fed poorly, and he had diarrhea and respiratory distress. Methemoglobinemia (20.5%) and reduced oxyhemoglobin saturation (79%) were identified. The patient had an excellent clinical response following a single IV dose of methylene blue. Subsequently, methemoglobin reductase activity was normal and there was no measurable hemoglobin M. The diagnosis of methemoglobinemia should be considered in any infant receiving large doses of metoclopramide who has clinical findings of cyanosis, ashen color, or a history of lethargy and/or motor restlessness.

The National Cancer Institute of Canada (NCIC) Clinical Trials Group has carried out a phase II study of acivicin given as a 72-hour continuous infusion in previously untreated patients with measurable metastatic colorectal carcinoma. Toxicity in 24 patients was mild to moderate and consisted primarily of GI symptoms such as nausea, vomiting, diarrhea or CNS changes including drowsiness, lethargy, dizziness. No responses were seen in 23 evaluable patients. We did not find acivicin given as described to be effective in colorectal carcinoma.

Gnotobiotic pigs inoculated with an Escherichia coli O157:H7 strain isolated from a human with hemorrhagic colitis developed anorexia, lethargy, and watery diarrhea. Bacteria diffusely colonized the cecum and colon surfaces and the crypt epithelium. At bacterial attachment sites, microvilli were effaced, and epithelial cells were irregularly shaped, rounded, or detached. Submucosa, lamina propria, and mesentery were markedly edematous and contained many inflammatory cells.

Despite the widespread use of non-steroidal anti-inflammatory drugs (NSAIDs), the current number of reported cases of poisoning is small. However, with the introduction of 'over-the-counter' preparations of NSAIDs in some countries (e.g. ibuprofen in the UK and USA) an increased incidence of acute poisoning from this group of drugs can be expected. Conventionally, NSAIDs are divided into the following groups based on their chemical structure: arylpropionic acids, indole and indene acetic acids, heteroarylacetic acids, fenamates, phenylacetic acids, pyrazolones and oxicams. Unless NSAIDs are ingested in substantial overdose, acute poisoning with these agents does not usually result in significant morbidity or mortality. In most cases the clinical features are mild and confined to the gastrointestinal and central nervous systems, though acute renal failure, hepatic dysfunction, respiratory depression, coma, convulsions, cardiovascular collapse and cardiac arrest may complicate severe poisoning. Arylpropionic acid derivatives were thought initially to have a low order of toxicity in overdose but, in addition to anticipated gastrointestinal symptoms, headache, tinnitus, hyperventilation, sinus tachycardia, hypoprothrombinaemia, haematuria, proteinuria and acute renal failure have been described. In addition, drowsiness, coma, nystagmus, diplopia, hypothermia, hypotension, respiratory depression and cardiac arrest have been reported in severe cases of poisoning. Oxyphenbutazone and phenylbutazone are considerably more toxic in overdose. Complications of severe poisoning include coma, convulsions, hepatic dysfunction, acute renal failure, sodium and water retention, haematuria, cardiovascular collapse, respiratory alkalosis, metabolic acidosis, hypoprothrombinaemia and thrombocytopenia. In contrast, indomethacin appears to be much less toxic. In addition to gastrointestinal symptoms, indomethacin taken in overdose induces headache, tinnitus, dizziness, lethargy, drowsiness, confusion, disorientation and restlessness. Only 1 case of acute sulindac poisoning has been reported in the literature. A 16-year-old boy was admitted with hypokalaemia (2.2 mmol/L), transient granulocytosis and 'scanty' haematemesis after ingesting 12 g sulindac. No case of acute tolmetin poisoning have been reported. The fenamates (flufenamic acid, meclofenamic acid, mefenamic acid, tolfenamic acid) are, with the exception of mefenamic acid, not as widely prescribed as other groups of NSAIDs. In overdose, mefenamic acid may result in nausea, vomiting, diarrhoea, muscle twitching, convulsions and coma.(ABSTRACT TRUNCATED AT 400 WORDS)

An acutely lethal LCMV disease model has been established in the Syrian golden hamster (Mesocricetus auratus) in which lethality and disease are dependent upon both the inbred hamster strain and the LCMV strain. Young adult inbred, male and female, hamsters were tested for lethal-disease susceptibility by lymphocytic choriomeningitis virus (LCMV) strains, WE or Armstrong (ARM). With WE inocula, PD4 and MHA inbred hamsters were highly susceptible to a wasting disease. LVG and LHC inbred hamsters were intermediate in susceptibility; some of these animals died of wasting illness, and others exhibited minimal disease and survived. CB and LSH hamsters were highly resistant to any disease by WE. Mean survival times of susceptible hamsters given lethal WE inocula approximated 2.5 weeks and were not dependent on virus dose. By 1.5 weeks after WE inoculation wasting disease signs were notable and consisted of lethargy, progressive body weight loss, and diarrhea. The LCMV strain, ARM, was avirulent for all hamster strains, causing neither death nor disease. Hamsters surviving WE or ARM inoculation appeared healthy, produced LCMV antibody, and acquired resistance to further lethal WE challenge. Despite hamster-lethality differences. WE and ARM appeared comparably immunogenic for all hamster strains, based on host antibody titers. A number of other differences between the LCMV strains were, however, noted which could be relevant to virus virulence and lethality for hamster hosts. These included guinea pig lethality, temperature sensitivity, and plaque morphology.

Clinical salmon poisoning disease (SPD), and survival of Neorickettsia helminthoeca and metacercariae of Nanophyetus salmincola in fish were evaluated experimentally in 12-wk-old coyotes (Canis latrans) to determine the potential of SPD for biological control of coyotes. Coyotes readily ate fish that contained metacercariae and rickettsiae. They developed diarrhea, anorexia and lethargy within 7 days after feeding. Infected coyotes lost 58% of their body weight when compared to uninfected controls. They died or became moribund and were euthanatized within 17 days after feeding. Rickettsiae were present in the macrophages of lymph nodes of all affected coyotes. Clinical disease occurred in coyotes fed fresh fish, but not in coyotes fed fish stored at 4 C for greater than or equal to 30 days or at -20 C for 14 days. Metacercariae in fish were viable after 60 days at 4 C. These trematodes developed in coyotes, but clinical SPD did not occur. This indicated survival of metacercariae, but not rickettsiae. Metacercariae were not viable after 14 days at -20 C.
