We observed eight infants with hereditary fructose intolerance which had been diagnosed by the fructose tolerance test and an aldolase assay on biopsied liver. None of these had been diagnosed before their admission to our department. The most frequent symptoms were vomiting and failure to thrive. All the patients had hepatomegaly. Laboratory findings were indicative of disturbed hepatic function. Hypoglycemia was found in only 3 out of 8 patients. The course was lethal in 2 patients; the 6 survivors are doing well following a fructose-free diet. The importance of practising paediatricians having the detailed nutritional history of the patient and precise knowledge of infant food formulae is stressed. The danger of using fructose continuing solutions for infusion therapy is pointed out. We also report a case of F-1,6-diphosphatase deficiency.

Case reports are presented that link the use of oral contraceptives (OCs) to liver disease, particularly to the Budd-Chiari syndrome. This syndrome is caused by occlusion of hepatic veins and although a causative relation between OC use and this syndrome is not proven, these facts support an association: 1) the known increased incidence of venous thrombosis in women using OCs; 2) data from a review of 164 cases of the syndrome showed that in 1959 men and women suffered the syndrome about equally, but since 1975 after the introduction of OCs another study reported women contracting the disease twice as often as men; 3) the syndrome is associated with pregnancy; and 4) since the 1975 study, association with the pill was found in 16 reported cases. Clinically, the average age of these 16 women with OC-associated Budd-Chiari syndrome was 32 years. Length of time before onset of symptoms after beginning OC therapy varied from 2 weeks to 8 years (mean 23.8 months). In most cases, abdominal pain, nausea, vomiting, and abdominal distension were present. Hepatomegaly and ascites were described in most cases and splenomegaly in less than half. Liver function abnormalities were nonspecific. Prognosis is not good, and management techniques for the syndrome have been largely unsuccessful. Metabolic alterations of steroids as they pass through the liver may account for the syndromes associated with OC use. 3 major diseases or effects are linked with OCs: hepatic dysfunction, cholestatic jaundice, and benign hepatic tumors and peliosis hepatis; these, however, are benigh complications compared with the severity of contracting Budd-Chiari syndrome, and the clinician should respect a woman's decision not to use the pill in the face of such disease-inducing possibilities.

Recurrent episodes of hypoglycemia, prostration, vomiting, and hepatomegaly were observed in an infant fed a carnitine-free soy formula. The extremely low plasma and urinary carnitine concentrations, elevated plasma free fatty acids, disproportionately low plasma beta hydroxybutyrate, and elevated urinary dicarboxylic acids, in the presence of a fatty liver, suggested that carnitine deficiency was the basis for this child's metabolic disturbance. When the infant was fed an enriched carnitine diet, remarkable clinical, biochemical, and histologic improvement was observed. The possibility that carnitine may be an essential nutrient for some infants is raised by the findings in this patient.

A baby with congenital lactic acidosis is described. The blood levels of lactic acid and alanine as well as the excretion of these compounds in the urine were largely elevated. Clinically the illness presented with vomiting, poor feeding, areflexia, muscular hypotonia and hepatomegaly. The baby died at the age of three months. The pyruvate dehydrogenase complex in cultured fibroblasts showed an activity of 14% of normal values.

In a survey of 15,272 canine necropsies, natural infection with Mycobacterium tuberculosis was found to have been diagnosed in eight dogs (0.05%). Clinical findings were anorexia, loss of body weight, lethargy, vomiting, and leukocytosis; radiography revealed pleural and pericardial effusion, ascites, and hepatomegaly. Granulomatous lesions with acid-fast bacilli were consistently found. Mycobacterium tuberculosis was isolated from lesions in the lungs, liver, or lymph nodes of five dogs. All eight dogs had a history of contact with human patients with tuberculosis.

A retrospective chart review for the 1993 calendar year identified 187 children with cerebral malaria admitted to a large teaching hospital in central Ghana, West Africa. The most common clinical presentation was fever, sensorial depression and convulsions in young children experiencing their first episode of malaria. One-half had splenomegaly. Additional features, seen in decreasing frequency, were hepatomegaly, vomiting, abdominal pain and headache. Long term sequelae were identified in 9% and mortality in 6%. Risk factors for central nervous system disease were negative history for previous malaria (P < 0.005) and a high percentage of parasitemia (P < 0.001). Death or long term sequelae were associated with multiple seizures and prolonged sensorial depression. The incidence of malaria is currently increasing in Western Africa and young children are more likely than older children to develop severe disease.

The clinicopathological features of a previously unrecognised type of acute encephalopathy prevalent among Japanese children is described by reviewing the records of 13 consecutive patients treated and 28 previously reported cases. The hallmark of this encephalopathy, proposed to be a novel entity termed acute necrotising encephalopathy of childhood, is multiple, necrotic brain lesions showing a symmetric distribution. The encephalopathy was noted in previously healthy children after respiratory tract infections, with presenting symptoms of coma, convulsions, vomiting, hyperpyrexia, and hepatomegaly. Laboratory examinations disclosed liver dysfunction, uraemia, and hypoproteinaemia. The histological appearance of the liver was variable and non-specific. Cerebrospinal fluid contained an increased amount of protein. Computed tomography and MRI showed the presence of symmetrically distributed brain lesions of the thalamus, cerebral white matter, brainstem, and cerebellum. Necropsy examination confirmed extensive fresh necrosis of these regions with evidence of local breakdown of the blood-brain barrier. Based on the characteristic combination of clinical and pathological findings, acute necrotising encephalopathy of childhood can be distinguished from previously known encephalopathies, including Reye's syndrome.

Schistosoma mansoni was introduced in the Richard Toll area (Senegal) around 1988, probably due to man-made ecological changes in the Senegal river basin. Since 1991, we investigate the community of Ndombo, close to Richard Toll. Four random population samples of approximately 400 subjects are surveyed, starting at 8 months intervals. Each cohort is examined parasitologically (Kato-Katz), clinically, serologically (circulating antigen and antibody profiles); treated with praziquantel 40 mg/kg; and followed up 6-12 weeks, 1 and 2 years after treatment. Water contact patterns and snail densities are longitudinally surveyed. In the first cohort, prevalence of infection was 91%, with 41% excreting over 1000 eggs per gram (epg); the mean egg count was 646 epg, individual counts up to 24,000 epg. Prevalences remained almost 100%, but egg counts declined strongly in adults, in spite of continued exposure and the supposed lack of acquired immunity. Antigen detection in serum and urine confirmed that the egg counts genuinely reflect variations of worm burdens. Serum circulating anodic antigen (CAA) provided intriguing epidemiological information on worm burdens, while circulating cathodic antigen (CCA) showed promise for non-invasive diagnosis and screening. So far, similar epidemiological results were found in subsequent cohorts, although some variations were observed, possibly due to seasonal transmission fluctuations. IgE levels increased with age, while IgG4 peaked in the age-group 10-19 years. IgE and IgG4-levels against adult worm antigen (AWA) and soluble egg antigen (SEA) increased between cohort 1 and cohort 3 in almost all age-groups. In all 3 cohorts examined so far a strong correlation between IgG4 and pre-treatment egg-load was observed. Further follow-up and analysis, and comparison with chronically infected populations will provide insight in the development of acquired immunity. Abdominal discomfort was reported by 61% and diarrhoea by 33% of the subjects in the first cohort; mild hepatomegaly was found in 16%, splenomegaly in 0.5%. There was no correlation between frequency of symptoms and egg counts. This low morbidity, in spite of intense infections, was confirmed by ultrasound, and may be due to the recent nature of the focus. In the first cohort, 82% of treated subjects still excreted eggs 12 weeks after treatment, though egg counts declined strongly. Antigen detection confirmed these results. Parasitological negativation rates in subsequent cohorts, followed up sooner after treatment, improved but remained remarkably low. The low drug efficacy may be due to very rapid reinfection (though further reinfection after one year was limited), and/or to the lack of immunity in the population. Reduced susceptibility of the local schistosome strain can not be excluded, however. Praziquantel treatment provoked impressive but transient side effects (colics, vomiting, urticaria, oedema), the frequency of which correlated with intensity of infection.

The aim of this work was to offer a description of the clinical manifestations developed by patients under 1 year who had dengue virus infection and dengue hemorrhagic fever during the epidemic which broke out in 1981, and to determine if the passive transfer of maternal dengue antibodies to the fetuses influenced the occurrence of a severe development of the disease, through a retrospective study. In 20 cases, type 2 dengue virus infection was confirmed. Eight patients showed the clinical manifestations of dengue hemorrhagic fever of dengue shock syndrome (DHF/DSS), and the other 12 had the typical dengue virus infection. The former were of the white racial phenotype, aged under 6 months. There was a predominance of type 1 dengue antibodies in the mothers of children with DHF/DSS. Fever, rash, vomiting and diarrheas (not frequent) appeared in the two clinical manifestations of the infection; blood leukocytes were predominantly lymphocytic; and erythrocyte sedimentation was always normal. Patients with DHF/DSS presented with some bleeding (87.5%); cyanosis and ascites (37.5%); and shock (25%), as well as hepatomegaly. All these infants with DHF/DSS had thrombocytopenia and most of them showed hemoconcentration. No deaths occurred.

Late onset of symptoms in a 12 1/2-year-old male with ornithine transcarbamylase (OTC) deficiency were associated with unusual histological features in the liver. The patient presented with an acute onset of hyperammonemia and altered mental status after a 2-day prodrome of vomiting and lethargy. Physical examination showed a combative and disoriented male with icteric sclerae but with no fever or hepatomegaly. The plasma ammonia level was 282 microM. Enzyme assays of liver tissue obtained by percutaneous needle biopsy showed OTC activity of approximately 3% of normal; carbamyl phosphate synthetase was normal. Histopathological findings included severe microvesicular centrilobular steatosis. Hepatic architecture and reticulin framework were well preserved. Many hepatocyte nuclei were filled with glycogen. Electron microscopy showed mitochondria that were rounded and expanded with cristae at the edge of the mitochondrial membrane. In contrast to other reports, only slight variations in size and shape were seen. Megamitochondria and intramatrical paracrystalline inclusions were not identified. The cytoplasm contained scattered fat globules, peroxisomes, and dilated smooth endoplasmic reticulum. The prominent mitochondrial abnormalities commonly found in OTC deficiency were notably absent.
