Thirteen out of 18 patients with fulminant hepatitis developed cerebral edema macroscopically confirmed at autopsy. Cerebral bleeding and herniation were also observed in 38 and 8% of edema cases, respectively. No significant difference was found in the clinical backgrounds (age, sex, laboratory data) of patients with and without cerebral edema. Respiratory distress (100% of edema cases, p less than 0.05), abnormal pupils (89%, p less than 0.10), convulsions (61%) and tachycardia unrelated to fever (60%) were more frequently observed in cerebral edema cases than in those without edema. The frequency of convulsions increased as hepatic encephalopathy progressed, and the frequency of respiratory distress and abnormal pupils in edema cases was significantly higher at the coma grade V of hepatic encephalopathy. Tachycardia was detected early, even at the mild grades of hepatic encephalopathy. These results suggest that symptoms due to cerebral edema such as convulsions, abnormal pupils and respiratory distress should be distinguished from those due to hepatic encephalopathy in fulminant hepatitis patients.

A red-tailed hawk (Buteo jamaicensis) with signs of respiratory distress and diarrhea was captured in the Manchac Wildlife Management Area, Louisiana (USA) and died the following day. At necropsy, the carcass was emaciated and there were splenomegaly, and fibrinous pericarditis, airsacculitis, and perihepatitis. Microscopically, there were fibrinous pericarditis and airsacculitis, myocardial necrosis, necrotizing hepatitis, splenic necrosis with reticuloendothelial cell hyperplasia, interstitial pneumonia and focal pancreatic necrosis. Intracytoplasmic chlamydial inclusion bodies were noticed in macrophages in the fibrinous exudate covering air sac and pericardium, and in spleen, liver, heart, lung, and pancreas. Schizonts compatible with a Sarcocystis sp.-like protozoon were present in the walls of air capillaries in the lung. A Chlamydia sp.-like organism was isolated in embryonating chicken eggs and cell culture and identified as C. psittaci with immunofluorescent staining.

A 3-year-old 4-kg neutered male domestic shorthair cat died within 5 days after onset of fever and respiratory distress. At necropsy, all tissues were icteric, and the liver had a diffuse reticular pattern. Histologically, hepatitis and encephalitis were associated with Toxoplasma gondii tachyzoites. Toxoplasma gondii female gamonts and oocysts were found in epithelial cells of intact villi and in epithelial cells desquamated into the lumen. Finding of acute hepatitis and T gondii oocysts in an adult cat without detectable immunodeficiency is unusual, because adult cats rarely have clinical signs of toxoplasmosis during the oocyst-shedding phase.

Subjects with a variety of enteropathies, hemolytic anemias, acute respiratory distress syndrome, hepatitis, Gaucher's disease as well as those on TPN and hemodialysis, often have low ("deficient") blood levels of vitamin E. A deficiency of vitamin E can be manifested by accelerated red blood cell destruction and neuromuscular deficit. Supplementation of these patients may be advisable. Neurological dysfunction has been observed in adults with prolonged vitamin E deficiency resulting from lipid malabsorption. Long-term treatment with high doses of vitamin E results in improvement. Administration of 800 IU/day of vitamin E to subjects with G6PD deficiency, sickle-cell anemia and beta-thalassemia has resulted in improvement of hematological parameters. Supplementation with 300 IU/day for 3-6 months has resulted in improved walking distances and improved blood flow in patients with intermittent claudication. In a limited number of controlled studies, 300-600 IU/day resulted in improvement in premenstrual syndrome, tardive dyskinesia and also arthritis. Epidemiological studies suggest that high levels of serum vitamin E are associated with lower risk of certain cancers, cardiovascular disease and infections. In some cases the high levels are difficult to obtain by diet alone. High levels of vitamin E are contraindicated in subjects who are receiving vitamin K antagonists as anticoagulant therapy. Except for this interaction with vitamin K, there are no specific side effects associated with high doses of vitamin E. Thus, there are various reasons for supplementations with vitamin E and, with the exception noted, the risk of such supplementation is very low.

A syndrome is described that affected 16 Indian and Inuit infants roughly 3 months old, most of whom were born in settlements in the Canadian Arctic. The infants presented with a clinical picture that included hepatitis, hemolytic anemia, rickets and respiratory distress, a combination that resembled a syndrome first described in malnourished infants at the turn of the century by von Jaksch and Luzet. The clinical course was self-limited, and all the infants survived without sequelae. The cause of the syndrome was not determined; no infectious agents were discovered. However, low levels of vitamins A, C, D and E were found in a few infants in whom assays were done. The implications of these findings and their relation to the possible cause of this "northern infant syndrome" are discussed.

During the past few years, there has been an apparent increase in serious infections due to group A streptococci (GAS) worldwide. We describe our experience with severe invasive GAS infections in Ontario, Canada, during the past 5 years (February 1987 through December 1991). A case was defined as the isolation of GAS from blood or normally sterile tissue in association with hypotension (systolic blood pressure, < 90 mm Hg). Fifty cases were identified in patients ranging in age from 4 to 100 years (median age, 47 years); 29 (58%) of the patients died. A primary focus of infection was identified in 38 cases (76%), with soft tissue being the site involved most frequently (68%). No focus of infection was found in 12 patients, and 36 patients (72%) were bacteremic. Complications included acute respiratory distress syndrome (21 of 50), acute renal failure (20 of 50), hypocalcemia (19 of 24), elevated creatinine kinase values (21 of 27), coagulation abnormalities (15 of 21), and hepatitis (15 of 24). Eleven cases (22%) were nosocomial; one of these was secondary to another nosocomial case. Thirty-three isolates were available for M and T typing and for determination of the presence of the genes for streptococcal pyrogenic exotoxin (SPE). The most frequent types were M1T1 (10) and M12/T12 (8). Twelve isolates possessed the speA gene, and 16 isolates had the speC gene. Only three isolates possessed both speA and speC. All isolates possessed the speB gene.

1.286 patients were diagnosed as DIC, among 123.231 patients who were admitted in the 285 departments of the university hospitals in Japan, in 1992. The incidence of DIC was high in acute promyelocytic leukemia, fulminant hepatitis, abruptio placentae, acute respiratory distress syndrome, and sepsis. In cases of DIC, bleeding tendency due to consumption coagulopathy is most important, but organ dysfunction due to circulatory disturbances by development of multiple thrombi is also noteworthy. As a whole, DIC may be divided in two types. The first type is cases of DIC with severe bleeding symptoms. However, except cerebral hemorrhage, organ dysfunction is rare in these cases. These cases may be called as "fibrinolysis-dominant DIC", because hemostatic thrombi as well as thrombi which cause organ dysfunction by circulatory disturbances are rapidly removed by abnormally enhanced fibrinolysis. The second type involves cases of DIC with severe organ dysfunction. Bleeding symptoms in these cases are usually not severe. These cases may be called as "coagulation-dominant DIC". The most typical causative disease of the fibrinolysis-dominant DIC is acute promyelocytic leukemia. The most typical causative disease of the coagulation-dominant DIC is sepsis. The presence of causative disease of DIC, elevation of FDP, and depletion of platelet count are most important to diagnose DIC. In the treatment of DIC, removal of cause of DIC, administration of heparin to protect further development of multiple thrombi, and replacement of platelets in cases of acute leukemia are most important.

Ischemic hepatitis, a relatively infrequent disorder occurring in 0.16% to 0.50% of patients admitted to medical intensive care units, often follows episodes of hypotension or acute heart failure. Investigating the clinical characteristics of patients with ischemic hepatitis may add to our understanding of the pathogenesis and significance of this syndrome. We therefore conducted a retrospective analysis of 34 patients to examine the possible contribution of the various baseline characteristics to the severity of the hepatic damage. In all patients liver disease was unexpected and in some, liver dysfunction dominated the clinical picture. All patients had high serum glutamic pyruvic transaminase (SGPT) and lactic dehydrogenase (LDH) levels (mean +/- SE, 2073 +/- 255 international units and 6085 +/- 748 international units, respectively). The mean SGPT/LDH ratio was 0.34. Most patients had coagulopathy with a prolonged prothrombin time (mean +/- SE, 5.86 +/- 1.37 international normalized ratio [INR]). The most common diagnosis on admission was respiratory distress secondary to various causes. Before the development of the hepatic dysfunction, respiratory failure and hypoxemia were observed in 68% of the patients, whereas hypotension was observed in only 38%. More than 90% of the patients had three or more associated comorbid conditions. The most frequent of these were left heart failure (88.2%), right heart failure (67.6%), chronic obstructive lung disease (58.8%), and chronic renal failure (55.9%). During the acute episode, more than 90% of the patients had transient deterioration of their renal functions. Hypoglycemia was noted in 11 patients (32.4%), and the glucose level was inversely correlated with the SGPT level (r = -0.43, p = 0.01). Stepwise multiple regression analysis showed that left heart failure, systolic blood pressure lower than 90 mm Hg, and female gender, together, accounted for 34% of the variance of the peak SGPT levels (p = 0.002). Fourteen (41.2%) patients died during the 3-month follow-up period, but none from the hepatic injury. None of the clinical or laboratory parameters measured predicted mortality. Clearly, ischemic hepatitis is associated with a high risk of death. The characteristic patients are those with multiple underlying systemic diseases and conditions, especially those with left heart failure. Liver function test results and levels of liver enzymes should be monitored in these patients, particularly when they are admitted for respiratory deterioration and episodes of hypotension.

The prevalence of hypomagnesemia was studied in neonates and children. The specimens were selected randomly from those submitted to the clinical chemical laboratory for blood test. A serum magnesium concentration less than 0.74 mmol/L was considered hypomagnesemic. A total serum magnesium determinations of 910 patients showed that 188 (21.7% prevalence rate) patients contained low serum magnesium levels. Frequently encountered hypomagnesemia was found among neonates with clinical conditions as diarrhea 41 (21.8%), premature births 24 (12.8%), neonatal hepatitis 20 (10.6%) and respiratory distress syndrome 5 (2.7%). In children the clinical conditions most frequently encountered with low serum magnesium were seizure 30 (16%), renal disease 26 (13.8%), metabolic acidosis 18 (9.6%), ideopathic apnea 14 (7.4%) and tachycardia 10 (5.3%). The statistical analysis of low serum magnesium values of patients in various clinical groups showed a significant difference (p < 0.0001) upon using homogeneity of variances but this was insignificant with the application of Kruskal-Wallis 1-Way ANOVA since Chi-square = 12.5748.

We report a case of leptospiral infection in a 63-year-old man who acquired the infection while swimming in canals and streams in Hawaii. The patient's course was atypical in that he was anicteric and had no evidence of meningitis when he presented with fever, rapidly progressive and severe rhabdomyolysis, thrombocytopenia, acute renal failure, and respiratory distress syndrome. Although he recovered after a protracted illness, he required major life support, including mechanical ventilation and hemodialysis. Initial antimicrobial therapy was designed to cover major bacterial and atypical pathogens, including leptospires. An in-depth work-up for causes of this catastrophic illness confirmed acute leptospirosis. Although rare, leptospirosis is a potentially lethal infection classically associated with hepatitis, azotemia, and meningitis. Most patients experience self-limited illness, with fever, myalgias, and malaise followed by an immune-mediated aseptic meningitis. A small proportion develop shock and multiple organ dysfunction. Whereas myalgias are ubiquitous in leptospiral infection, and most patients show mildly elevated muscle enzymes, life-threatening rhabdomyolysis is rare. This atypical case is reported to urge clinicians to consider leptospirosis in the evaluation of a patient with cryptogenic sepsis who develops multiple organ dysfunction associated with rhabdomyolysis. Appropriate antimicrobial therapy, with penicillin or doxycycline, can be life-saving.
