Pleural effusion, secondary to a metastasis from a malignant hepatoblastoma, was diagnosed in a 3-year-old Appaloosa gelding. Severe hemorrhagic transudate in both pleural cavities resulted in acute onset of labored breathing, tachypnea, tachycardia, and jugular vein pulsation. Results of ultrasonography and radiography of the ventral lung field and cranial portion of the abdomen initially were nondiagnostic, as were results of cytologic examination of peritoneal fluid and tracheal wash specimens. Moderately high serum gamma-glutamyl transferase and alkaline phosphatase activities, despite normal hepatocyte-specific enzyme (sorbital dehydrogenase) activity, were indicative of biliary stasis without hepatocyte destruction. The horse was euthanatized. Necropsy revealed a 47-kg hepatoblastoma, with metastases in the lungs and intestines.

A patient who developed chronic salicylism associated with salicylate therapy for treatment of juvenile rheumatoid arthritis is described, and the clinical presentation and treatment of chronic salicylism are reviewed. A 5 1/2-year-old boy was receiving aspirin 150/mg/kg/day for treatment of juvenile rheumatoid arthritis. While on salicylate therapy, the patient developed tachypnea and became increasingly hyperthermic, lethargic, and disoriented. The patient developed a maculopapular rash, weakness, and a decreased level of consciousness during the 11 days before admission to the hospital. Physical examination and laboratory determinations revealed that the patient had hypoprothrombinemia, hypoglycemia, and severe hepatic encephalopathy secondary to long-term salicylate toxicity. The patient was treated for hypoglycemia, electrolyte imbalances, thrombocytopenia, and anemia and was discharged after 24 days. Diagnosing chronic salicylism with hepatic dysfunction was difficult because the symptoms are similar to those of stage I to stage II Reye's syndrome. Liver enzymes, including aspartate aminotransferase (also called SGOT), alanine aminotransferase (also called SGPT), alkaline phosphatase, and lactate dehydrogenase, may be elevated in juvenile arthritis patients with hepatic dysfunction. Liver dysfunction usually improves when salicylate therapy is discontinued. Supportive therapy should always be used in symptomatic patients. Children on long-term, high-dose salicylate therapy should be monitored closely, and baseline liver function tests should be performed. The clinical effectiveness of administering sodium bicarbonate in attempts to alkalinize urine and increase salicylate elimination is controversial. In patients with juvenile rheumatoid arthritis who develop chronic salicylism, careful analysis of the patient's medication history, laboratory values, and clinical presentation are necessary to rule out Reye's syndrome.

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.

BACKGROUND: The pattern of liver function tests (LFTs) in community-acquired pneumonia has not been investigated in detail. Although abnormal tests are thought to be more frequent in patients with atypical pneumonia, the prognostic value of LFTs have not been clearly established. METHODS: We assessed 96 consecutive patients admitted to one hospital with a chest infection over a period of 6 weeks. The infection was classified as bronchitis or lobar pneumonia on clinical and radiological criteria. The site and severity of the infection were assessed and correlated with LFTs and standard British Thoracic Society prognostic criteria. Mortality and length of stay in survivors were used as major outcome measures. RESULTS: There were 17 deaths (18%) overall and patients with abnormal LFTs were significantly more likely to die than those with normal tests (25% vs. 5%; p=0.026). Length of stay was significantly longer in survivors with abnormal liver function than in those with normal tests (9.7 vs. 5.8 days; p=0.006). A low albumin was the most useful predictor of poor outcome and carried a relative risk of dying of 1.8, comparable to the predictive value of tachypnoea. ALT was increased threefold in those succumbing to their disease, but alkaline phosphatase levels were not predictive of outcome and an increase in gamma GT appeared to be protective. CONCLUSIONS: Abnormal LFTs are common in community-acquired pneumonia and are of prognostic value. Patients with a low albumin or raised ALT are significantly more likely to die from their disease or to stay in hospital for a prolonged period. However, other LFTs are of less value in predicting prognosis.

A 10-year-old, female spayed mixed-breed or cross-bred dog was referred to the Small Animal Teaching Hospital of the University of Liverpool due to tachypnea, dyspnea, and pleural effusion not responding to diuretics and antibiotics. The chest was drained and cytology of the pleural fluid was consistent with a modified transudate with presence of atypical cells initially attributed to mesothelial hyperplasia and dysplasia. Computed tomography detected, in addition to the bilateral pleural effusion, diffuse pleural thickening, multiple pleural and pulmonary nodules, and a mineralized and lytic mass in the left scapula. Imaging findings were suggestive of a primary bone tumor with intrathoracic metastasis. Cytology of the left scapular and pleural masses revealed a malignant neoplasm highly suggestive of osteosarcoma. The diagnosis was confirmed by demonstration of a positive cytochemical reaction for alkaline phosphatase on prestained cytology slides. This finding prompted review of the initial interpretation of the pleural effusion cytology. The presence of neoplastic osteoblasts in the thoracic fluid was identified by a combination of cytochemistry, cell pellet immunohistochemistry, and transmission electron microscopy findings. In this report, a multidisciplinary integrated diagnostic approach was used to diagnose and confirm a neoplastic pleural effusion due to osteosarcoma metastasis in a dog.
