A 79-year-old female was admitted to our hospital because of a malignant pleural effusion following mastectomy 4 years ago. In the patient's history arterial hypertension and previous inferior myocardial infarction have been known. Two doses of 20 mg mitoxantrone were installed intrapleurally at an interval of 4 weeks. Six hours after the second mitoxantrone application and the patient had increasing dyspnea with consecutive left heart failure, pulmonary congestion, and a drop of blood pressure. The white-cell count was 14800/mm3. The levels of creatinine phosphokinase (CPK), lactate dehydrogenase (LDH) and serum aspartate aminotransferase (SGOT) were in the normal range. Transthoracic echocardiography showed concentric left ventricular hypertrophy and a markedly decreased fractional shortening, but no left ventricular dilatation. The electrocardiogram showed newly appeared down-sloping ST-segments and inverted T-waves. Clinical recovery was achieved after 6 days by application of oxygen, dobutamine and furosemide followed by angiotensin converting enzyme inhibition and digitalis. In the echocardiographic control examination 14 days later left ventricular function had normalized. The changes of electrocardiogram normalized 4 weeks later.

The indolizidine alkaloid swainsonine, a potent inhibitor of Golgi alpha-mannosidase II, has been shown to reduce tumor cell metastasis, enhance cellular immune responses, and reduce solid tumor growth in mice. In our previous Phase I study, swainsonine administered by 5-day continuous infusion inhibited L-phytohemagglutinin-reactive N-linked oligosaccharide expression on peripheral blood lymphocytes. Significant toxicities included edema and elevated serum aspartate aminotransferase (AST). One patient with head and neck cancer had objective (>50%) tumor remission. Two patients showed symptomatic improvement. The objectives of this Phase IB trial were to examine the pharmacokinetics, toxicities, and biochemical effects of bi-weekly oral swainsonine at escalating dose levels (50-600 microgram/kg) in 16 patients with advanced malignancies and 2 HIV-positive patients unsuitable for conventional therapy. Eastern Cooperative Oncology Group performance status was </=2. The maximum tolerated dose was defined as 300 microgram/kg/day due primarily to serum AST abnormalities and dyspnea. Other adverse events present in >20% of patients included increase in serum AST (all patients), fatigue (n = 9), anorexia (n = 6), dyspnea (n = 6), and abdominal pain (n = 4). Inhibition of Golgi alpha-mannosidase II occurred in a dose-dependent manner. Examination of immunological parameters revealed a transient decrease in CD25(+) peripheral blood lymphocytes and, in seven of eight patients, an increase in CD4(+):CD8(+) ratios at 2 weeks. Serum drug levels peaked 3-4 h following a single oral dose in most patients and were proportional to dose at levels >/=150 microgram/kg. We conclude that oral swainsonine is tolerated by chronic intermittent administration at doses up to 150 microgram/kg/day. Adverse events considered drug related were similar to those observed in the infusional study but with fatigue and neurological effects also noted. Investigations of alternative dosing schedules with low starting doses are suggested for further clinical testing.

Scrub typhus, a mite-transmitted zoonosis caused by Orientia tsutsugamushi, is a disease endemic to Taiwan. Serious complications in scrub typhus were more common in the past 4 years than reported previously. Between August 1993 and July 1997, 33 cases of scrub typhus were admitted at Tri-Service General Hospital. Symptoms and signs were: fever (100%), chills (39%), cough (24%), headache (21%), diarrhea (18%), dyspnea (18%), eschar (60%), adenopathy (33%), and rash (21%). Nineteen percent (6/32) had obvious leukopenia (WBC < 4000/ mm3), 34% (11/32) had leukocytosis(WBC > 10,000/mm3) and 44% (14/32) had thrombocytopenia (platelet count < 100,000/mm3). Elevation of aspartate aminotransferase (AST) and elevation of alanine aminotransferase (ALT) were 81% (26/32) and 75% (24/32), respectively. Serious complications included pneumonitis 36% (12/33), acute respiratory distress syndrome (ARDS) 15% (5/33), acute renal failure 9% (3/33), myocarditis 3% (1/33) and septic shock 3% (1/33). One patient died of ARDS due to delay in diagnosis. Other patients recovered after appropriate antibiotic and intensive supportive treatments. Emerging virulent strains of O. tsutsugamushi in Taiwan might be biologically plausible. Scrub typhus should be considered in a patient with fever, varying degree of respiratory distress, particularly if there is an eschar or a history of environmental exposure in endemic areas. Prompt diagnosis, timely antimicrobial therapy and intensive supportive care are important for ARDS and other life-threatening complications.

Records of final diagnoses based on necropsies performed on dogs and cats over a 4.5-year period at a university teaching hospital were examined for the diagnosis of acute or subacute myocardial necrosis. Clinical findings signaling the occurrence of myocardial necrosis were often not specific, due to simultaneously occurring disease processes. However, of 28 animals identified, dyspnea occurred frequently (17/28; 61%) and in some cases in the presence of minimal pulmonary pathology (2/3; 66%) or otherwise unexplained pulmonary edema (4/4; 100%). Elevations in serum aspartate aminotransferase (10/10; 100%) and creatine kinase (5/9; 55%) were also frequent. Disease processes associated with thrombus formation were present for each case in which a coronary artery thrombus occurred (5/28; 18%).

We reviewed the clinical and laboratory findings for 19 cases of hantavirus pulmonary syndrome (HPS) identified either serologically or by immunohistochemical testing of archival tissue at our tertiary care center. Fever (95%), cough (89%), and dyspnea (89%) were the most common presenting symptoms. The most prevalent presenting signs were respiratory abnormalities (95%) and tachycardia (84%). Common laboratory findings included thrombocytopenia (95%) and leukocytosis (79%). Elevated aspartate aminotransferase and lactate dehydrogenase levels were found in all patients tested. Intubation was required in 58% of the patients, and inotropic support was required in 53%. Our study confirms that serological responses appear early during clinical illness, making the enzyme immunoassay a useful tool for the diagnosis of acute HPS. The mortality (26%) and severity of disease that we observed among patients with HPS appear to be less than those reported elsewhere.

Susceptibility of sheep to oral administration of Citrullus colocynthis fruits, Nerium oleander leaves or their mixture is described in 12 sheep assigned as untreated controls, C. colocynthis-treated at 0.25g/kg/day, N. oleander-treated at 0.25g/kg and plant mixture-treated at 0.25g of C. colocynthis/kg plus 0.25g of N. oleander/kg. The daily use of 0.25g of C. colocynthis/kg for 42 days was not fatal to sheep and caused slight diarrhoea, catarrhal enteritis, centrilobular hepatocellular fatty change and degeneration of the renal tubular cells. Single oral doses of 0.25g of N. oleander/kg were lethal to sheep within 18-24h and caused uneasiness, grinding of the teeth, dyspnoea, anorexia, frequent urination, ruminal bloat, ataxia and recumbency before death. The main lesions were widespread congestion and haemorrhage, pulmonary cyanosis and emphysema and severe hepatonephropathy. Rapid death was also observed in sheep receiving single doses of the mixture of the two plants. Effects were correlated with changes in the activities of serum lactic dehydrogenase (LDH) and aspartate transaminase (AST) and concentrations of cholesterol, bilirubin, total protein, albumin, globulin and urea and haematological parameters.

We present the first reported study of Ruta graveolens toxicity in 7-8-month-old Nubian goats. Oral administration of 5 g/kg bw per day of R. graveolens leaves caused tremor, dyspnoea, frequent urination, incoordination of movement, ataxia and recumbency, with death after 1-7 days. In goats receiving oral doses of 1 g/kg bw per day of the leaves, the course of toxicity was prolonged and the animals had pallor of the visible mucous membranes and loss in condition; one died on day 17, the others being slaughtered on days 41 and 46. The clinical effects were correlated with pathological changes in various organs, alterations in serum aspartate transaminase, creatine kinase, total protein, cholesterol, urea and other serum constituents, haematological values and the concentrations in the tissues of copper, iron, zinc, manganese, calcium and phosphorus.

An adult female Greek tortoise (Testudo graeca) presented with dyspnea, lethargy, and anorexia. Severe unilateral pulmonary candidiasis was diagnosed and confirmed by histologic and microbiologic evaluations. Initial treatment with ketoconazole resulted in plasma elevations of aspartate aminotransferase, lactate dehydrogenase, and bile acids consistent with imidazole-induced hepatotoxicity. Plasma chemistry abnormalities resolved upon withdrawal of the drug. Temporary osteotomy permitted access to the diseased lung and facilitated intrapulmonary catheterization. Intrapulmonary amphotericin B therapy at 0.1 mg/kg s.i.d. for 34 days proved to be both safe and effective in this case.

Over a period of 10 days, 17 dogs became weak and developed neurological deficits of different degrees of severity. About 12 hours before these clinical signs appeared they had all eaten a particular brand of commercial dog food from a recently opened bag. They were all quadriparetic and hyporeflexic, and some of them also showed additional systemic or neurological signs, including dyspnoea, a high body temperature, tongue laxity, hyperaesthesia and anisochoria. Serum biochemical abnormalities included high activities of creatine kinase, lactate dehydrogenase and aspartate aminotransferase. Analysis of the suspect food revealed high concentrations of the ionophore lasalocid. Fifteen of the dogs were given supportive treatment at home and two were hospitalised. Five of the dogs died, but the others improved gradually and had fully recovered by one to four days after the appearance of the clinical signs.

To investigate clinical course and outcome of dengue with acute respiratory failure (ARF), and to identify related risk factors for acquiring ARF in dengue, we retrospectively studied 11 dengue patients with ARF. From June to December 2002, a total of 606 adult patients were diagnosed as having dengue. Eleven (1.8%) of 606 dengue patients had complications of ARF. The main causes of ARF were sepsis (n = 6, 54.5%) and upper gastrointestinal (UGI) bleeding (n = 3, 27.3%). The mortality rate was 72.7% (n = 8). Additionally, univariate analysis showed that age, dyspnea, cough, prothrombin time, activated partial thromboplastin time, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, albumin, renal insufficiency, acute renal failure, acute hepatic failure, UGI bleeding, and combination bacterial infection were significantly predictive variables associated with dengue patients with ARF.
