Two patients requiring total parenteral nutrition for 34 and 39 months, had plasma and urinary carnitine assays and plasma lipid assays performed before and during intravenous administration of 400 mg (2500 mumol) of L-carnitine for 7 days, followed by 40 mg (240 mumol) daily continuously. One patient had generalized lethargy and weakness which resolved within the first 5 days of carnitine administration. The plasma-free carnitine levels in this patient rose significantly. The other patient was asymptomatic and while there was no significant change in the plasma-free carnitine levels during carnitine administration, this patient remained in positive carnitine balance throughout the study. There were no significant changes in plasma lipid levels in either patient. In adult patients requiring long-term total parenteral nutrition who are otherwise normal, intravenous L-carnitine may be required to supplement the patients endogenous carnitine production.

Nine of 105 cats with hyperthyroidism treated with propylthiouracil developed a serious immune-mediated drug reaction during treatment. Adverse clinical signs, which developed after 19 to 37 days (mean, 24.8 days) of propylthiouracil administration, included lethargy, weakness, anorexia, and bleeding diathesis. Physical examination revealed pale mucous membranes, and petechial hemorrhages of the skin and oral cavity. Results of hematologic testing revealed severe anemia and thrombocytopenia. The direct antiglobulin (Coombs') test was positive in all 7 cats evaluated, whereas the serum antinuclear antibody titer was greater than or equal to 1:10 in 5 of the 8 cats tested. In 4 of the cats, treatment included appropriate supportive therapy and cessation of propylthiouracil; in these cats, anemia and thrombocytopenia resolved and Coombs' and antinuclear antibody tests became negative within 2 weeks.

We evaluated clinical features of five cases of Toxoplasma encephalitis (TE) occurring in recent Haitian entrants into the United States. None of the patients had any underlying malignancy or known immunosuppressive therapy. Histopathologic findings of TE at autopsy were confirmed by peroxidase-antiperoxidase method. Four patients had an antecedent episode of disseminated tuberculosis and all five were receiving antituberculous therapy when neurologic manifestations of lethargy, seizures, and motor weakness first developed. These symptoms progressed into coma and death within 15 days. Peripheral lymphocytopenia was noted in all patients; three were anergic. Parenchymal lesions were identified by CT brain scans and total proteins were elevated in spinal fluid in all cases. TE appears to be a manifestation of the acquired immune deficiency syndrome in Haitians; it should be suspected in those with a febrile illness and multiple focal lesions of the central nervous system.

Presented is the case of an elderly woman who developed severe hyponatremia while taking tricyclic antidepressants. She met the criteria for the syndrome of inappropriate antidiuretic hormone secretion induced by drugs. Her symptoms of lethargy, weakness, and gastrointestinal disturbances developed insidiously, allowing the hyponatremia to reach severe levels before a diagnosis was made. A variety of psychoactive drugs, most prominently tricyclic antidepressants, have been reported to produce hyponatremia idiosyncratically in elderly persons.

The most common cause of hypoadrenocorticism in dogs is idiopathic immune-mediated destruction of the adrenal cortex. Other causes include anterior pituitary insufficiency, pituitary or adrenal neoplasia, acute withdrawal of exogenous corticosteroids, and mitotane toxicity. Females are affected more often than males; only 1 feline case has been documented. Animals 2-5 years old are most commonly affected. Clinical signs include lethargy, weakness, weight loss, anorexia, vomiting, diarrhea and bradycardia. Hematologic and biochemical changes can include eosinophilia, lymphocytosis, anemia, hyperkalemia, hyponatremia and hypercalcemia. Diagnosis is by finding negligible resting levels of plasma cortisol and no response to ACTH administration, and a serum Na:K ratio of 20:1 or less. Treatment involves restoring fluid volume, correcting acidosis, and supplementing salt and glucocorticoids. Daily oral use of prednisone at 0.05 mg/kg can safely maintain most affected dogs. Some dogs only require glucocorticoids in stressful situations. Iatrogenic secondary adrenocortical insufficiency (iatrogenic Cushing's disease) may result from a single injection of long-acting glucocorticoids or from long-term use. Clinical signs are the same as for natural hyperadrenocorticism, but endogenous cortisol release is suppressed. Treatment is gradual withdrawal of the offending glucocorticoid and elimination of the cause that initially prompted glucocorticoid therapy.

A prospective study was carried out to determine the effectiveness and tolerance of ftorafur (2.25 g/m2 daily for 5 days, repeated every 4 weeks) in previously treated patients with advanced squamous cell cancers of the head and neck. Seventeen patients were entered in the study; 15 were evaluable for drug toxicity, and 14 were evaluable for response. Three patients had mild nausea, three had mild-to-moderate lethargy, two had nonspecific generalized weakness, and two had severe stomatitis. Of 15 patients three experienced leukopenia (causing death in one) and four had thrombocytopenia (life-threatening to one). Response to treatment included: progressive disease (nine patients), stable disease (four), and complete response (one with no previous radiotherapy or chemotherapy).

Acute clinical malaria caused by Plasmodium inui was diagnosed in an adult female cynomolgus monkey (Macaca fascicularis) 4 years after importation into the United States. Stress and immunosuppression associated with experimentation completed 2 weeks earlier may have contributed to the development of severe clinical disease. Clinical findings included severe regenerative anemia, hepatosplenomegaly, weakness, lethargy, weight loss, and anorexia. The infection was treated and successfully eliminated with chloroquine hydrochloride administered intramuscularly at a dose of 5 mg/kg base given at 0, 6, 24, 48, and 72 hours. Treatment also included a blood transfusion and intensive supportive care.

Primary amebic meningoencephalitis and granulomatous amebic encephalitis are well recognized clinicopathological entities caused by free-living amebas. Associated arteritis and "mycotic aneurysms" with infiltration of intracranial arteries by lymphocytes, amebic trophozoites and cysts have not been previously reported. A 26-month-old girl had a 3-week history of encephalitis, characterized, initially, by vomiting and low-grade fever. Subsequently, she developed ataxia, generalized weakness, lethargy, and esotropia. The first CSF showed 490 RBC/microliters, 705 WBC/microliters with 90% mononuclears. Her pupils reacted briskly to light. Moderate nuchal rigidity, nystagmus, fixed downward gaze, anisocoria, bilateral 6th nerve palsy, left arm monoparesis and left Babinski were present. CAT scan revealed slight symmetrical dilatation of anterior horns of lateral ventricles and an area of abnormal enhancement above the 3rd ventricle. She died 14 days after admission, 5 weeks after onset of symptoms. The brain showed focal necrotizing encephalopathy, involving thalami, cerebellum, brain stem, and cervical and upper thoracic spinal cord. Numerous free-living amebic trophozoites and cysts were present within a chronic granulomatous encephalitis. There were trombosis of basilar, posterior cerebral, and vertebral arteries with profuse chronic panarteritis, fibrinoid necrosis, and mycotic aneurysms.

Chronic depletion of body chloride developed in a group of infants ingesting a diet consisting almost exclusively of chloride deficient Neo-Mull-Soy. Ten of the 12 infants were on this diet three to five months before loss of appetite, failure to thrive, muscle weakness, and lethargy led to a diagnostic evaluation. The outstanding laboratory features were severe hypokalemic metabolic alkalosis, low urinary chloride concentrations (< 10 mEq/liter), and erythrocyturia. There was marked decrease in weight for age in all 12 infants. Head circumference for age had decreased in five of six and length for age in five of ten infants for whom earlier measurements were available. The biochemical abnormalities reverted to normal following dietary supplementation with either sodium or potassium chloride. Appetite, affect, and muscle strength improved, and weight gain resumed. Head circumference for age has moved toward the percentile level present prior to starting Neo-Mull-Soy in all instances. With one exception, length measurements show a similar pattern. The erythrocyturia has decreased or vanished. Chloride deficiency led to contraction of the extracellular volume and the substitution of poorly reabsorbable anions for readily reabsorbable chloride. These alterations caused development of the negative hydrogen ion and potassium balances which led to the hypokalemic metabolic alkalosis.

More than 1200 patients who received pindolol for the treatment of hypertension, angina pectoris, and various arrhythmias in studies conducted in the United States were included in the New Drug Application submitted to the FDA. Nearly 1000 of these patients received pindolol as monotherapy. The side effects reported were generally transient and of mild or moderate severity. The most frequently reported side effects seen after pindolol administration, compared to those seen after placebo, were in decreasing order of incidence: headache, dizziness, insomnia, muscle pain, fatigue, weakness, nervousness, joint pain, edema, nausea, and muscle cramps. Other side effects that occurred more frequently with pindolol than with placebo but at a rather low incidence induced weight gain, bizarre dreams, visual disturbances, lethargy, and diarrhea. Nasal congestion, throat discomfort, nocturia, impotence, pruritus, anxiety, hypotension, bradycardia, and heart failure occurred only rarely. Of the 323 patients who received pindolol alone for the treatment of mild to moderate hypertension, only 20 (6.2%) were withdrawn from the study because of side effects. Overall, 3.4% of the patients treated with pindolol were withdrawn because of side effects, most of which involved the central nervous system, that is, insomnia, anxiety, dizziness, and headache. However, a few patients manifested some edema and weight gain while receiving pindolol alone. Review of the side effects data did not reveal a tendency for the incidence of side effects to be dose related. One placebo-controlled, double-blind study designed to evaluate the fixed dosages of 15, 30, and 60 mg in the treatment of mild to moderate hypertension suggested that only the incidences of insomnia and nervousness increased with increasing doses. However, these side effects were generally transient and of mild or moderate severity. The evidence indicates that pindolol has an acceptable safety profile and that any side effects that appear are generally well tolerated and disappear with continued treatment.
