    Notes: In contrast to Porphyria cutanea tarda (PCT), which is characterized by constant hepatic involvement, the liver seems to be unaltered in Porphyria variegate (PV). However, the authors have found microscopic alterations in the liver of 2 patients with PV (mild inflammation and fibrosis of the portal tracts and the presence of iron deposits in one of the cases). Although these changes could be attributed to other causes, the hypothesis of possible liver involvement in PV is not excluded.

    Notes: Various criteria have been proposed for the identification of early neoplastic changes in the setting of both small hepatocellular carcinomas and macroregenerative nodules. In this study we have applied those criteria to cases of liver cirrhosis without tumour (group I) and hepatocellular-carcinoma-associated cirrhosis (group II) to assess their discriminatory value in these two situations. Group I included 50 liver biopsies with uncomplicated cirrhosis while group II encompassed 48 liver biopsies of cirrhotic nodules adjacent to hepatocellular carcinomas. The histological changes sought were large cell dysplasia, small cell dysplasia, cytoplasmic basophilia, small microacinar structures, peripheral distribution of nuclei, nuclear irregularities and thickened liver cell plates. These changes were also assessed in macroregenerative nodules (nine in group I and seven in group II). None of these changes was useful to discriminate between group I and group II cirrhotic nodules when assessed separately. On the other hand, cirrhotic nodules showing three or fewer changes were never associated with malignancy, whereas those exhibiting four or more alterations were often located in the vicinity of a tumour. Acinar structures, thickened cell trabeculae, peripheral distribution of nuclei and nuclear irregularities seem to be the most specific indicators of proximity to a hepatocellular carcinoma. Similar results were obtained for macroregenerative nodules. These results may be helpful as guidelines to the probability of having a hepatocellular carcinoma elsewhere in livers containing atypical cirrhotic nodules, and may also prove valuable in the selection of appropriate material for investigating early molecular events in hepatic carcinogenesis.

    Notes: Summary In the past few years a new syndrome of invasiveCandida infection, the so-called hepatosplenic or chronic systemic candidiasis (CSC), has been recognized with increasing frequency in neutropenic patients. From January 1985 to December 1990, ten of 305 acute leukemia (AL) patients treated at our institution were diagnosed as having CSC. In contrast, during the same period this type ofCandida infection was not observed in any patient with hematological diseases other than AL treated in our center, including 277 patients who underwent bone marrow transplantation. All patients with CSC had fever and hepatomegaly, and five complained of abdominal pain. Seven patients had neutrophilic leukocytosis and six an increased serum alkaline phosphatase activity. Abdominal computed tomography and ultrasound study showed typical lesions in eight and seven patients, respectively. In four patients a laparoscopy-guided needle liver biopsy displayed yellowish nodules on the liver surface, and the histologic study revealed large granulomas with yeasts and pseudohyphae. All patients were given amphotericin B (mean: 4.6 g, range: 1–12.5 g) and 5-fluorocytosine, and five received fluoconazole. No patient died as a direct consequence of CSC and in six the infection resolved. Finally, once controlled, the infectious complication did not preclude subsequent intensive antileukemic therapy, including bone marrow transplantation.

    Notes: Summary Among 217 patients who received an allogeneic (136 cases) or autologous (81 cases) bone marrow transplant, the diagnosis of hepatic veno-occlusive disease (VOD) was established in 38 according to Seattle clinical criteria. Thirty-two underwent a transjugular liver biopsy and measurement of the hepatic venous pressure gradient (HVPG). The study was completed in 30 patients with no serious complications. Hepatic VOD was histologically confirmed in 18 patients (60%); the remaining 12 were classified as non-VOD. An increased HVPG discriminated well between VOD and non-VOD cases. Thus, hemodynamic data can considerably reinforce the accuracy of histological diagnosis. The predictive value of two vs. three clinical data of the Seattle criteria was analyzed. Among the 19 cases fulfilling two clinical data VOD was confirmed in only eight (42%), whereas VOD was proved in ten of 11 cases (91%) (p=0.02) suspected on the basis of three clinical data. When reliability of the Baltimore clinical criteria was analyzed, the result was identical to that observed when three Seattle clinical data were present. The specificity of the latter classification was high (92%) while its sensitivity was relatively low (56%). In conclusion, clinical criteria are not reliable for either recognizing or excluding the diagnosis of VOD. Thus, a transjugular liver biopsy, associated with hemodynamic evaluation, is strongly recommended when VOD is clinically suspected.

    Notes: Abstract  In order to determine the frequency and characteristics of patients with liver abnormalities as the presenting manifestation of Hodgkin's disease (HD), 421 consecutive HD patients were studied. Six patients in the series (1.4%) presented with liver abnormalities that led to of a liver biopsy and the subsequent diagnosis of HD. All had fever prior to HD diagnosis, four frank jaundice, and one hepatic failure. No patient had pruritus. Moderate hepatomegaly was present in four patients. Cholestasis was observed in all cases; in most patients a moderate increase in the transaminase activity was also seen. Two patients had a mild rise in the serum LDH, four had leukopenia, and one eosinophilia. At liver histologic study, Reed-Sternberg cells were demonstrated in four patients; in the remaining two, the presence of atypical histiocytes, lymphocytes, and eosinophils was highly suggestive of HD, the latter diagnosis being confirmed by subsequent study of bone marrow and/or retroperitoneal lymphadenopathies. In three of the six patients, HD was not demonstrated in sites other than the liver. Three patients older than 60 years died shortly after HD diagnosis. By contrast, three patients younger than 40 years showed a dramatic response to chemotherapy: two of them had a further relapse, and one is considered cured after 14 years of continuous remission. Liver disease constitutes an infrequent form of HD presentation which must be included in the differential diagnosis of any patient with fever of unknown origin.

    Notes: Abstract The prevalence of hepatitis B markers was determined in a representative sample of the general population of Catalonia (Spain). HBsAg was found in 0.5% of children (less than 15 years of age) and in 1.7% of adults (more than 15 years of age), and anti HBs in 1.6% and 18%, respecitvely. Age-specific prevalence for both markers showed a low risk for hepatitis B before puberty, and a progressive rise since adolescence, suggesting that perinatal transmission and horizontal transmission in children are relatively uncommon in Spain. Prevalence of hepatitis B markers was significantly higher among subjects with low education level, residing in an urban area and born outside Catalonia, but in the stratified analysis, a statistical significant difference was only maintained in the prevalence of HBV markers between those who live in urban and rural areas, and between those who were born outside Catalonia and in Catalonia. These data may be used as a basis for a strategy of hepatitis B prevention in Spain which include universal vaccination of adolescents, passive-active immunization of newborns to HBsAg positive mothers and vaccination of susceptible adults subjects from high-risk groups.

    Notes: Abstract 3 patients with hepatic cirrhosis and ascites underwent increased diuresis on six occasions, closely related to episodes of gastrointestinal bleeding. In each instance the increased urine volume was preceded by a sharp increase in blood urea nitrogen, presumably due to absorption of nitrogenous compounds from the gastrointestinal tract, suggesting a mechanism of osmotic diuresis. In each case there was a significant increase in serum sodium and osmolality, related to the greater-water-than-sodium diuresis induced by urea, which was promptly reversed by the administration of water or isotonic solution. Clinically this syndrome may be defined as the association of hypernatremia and hyperosmolality due to osmotic diuresis from urea appearing in a cirrhotic patient with ascites and gastrointestinal bleeding.

    Notes: Abstract Thirty seven strains of the Aspergillus flavus group isolated from animal mixed feeds have been screened for their ability to produce aflatoxins in yeast extract and sucrose (YES), aflatoxin producing ability (APA), and coconut agar medium (CAM) media. The concentration and detection of the aflatoxins by different methods is compared. Five known aflatoxin-positive and one aflatoxin-negative strains have been used as controls. Only 5 out of the 37 strains (13.5%) were aflatoxin-producers in YES medium. Of these five strains and the five known aflatoxin-positive strains, only three showed blue fluorescence in APA medium and four in CAM medium. Generally, the aflatoxin concentration in CAM medium was higher than in YES and APA media. Using the ‘agar-plug method’ and by direct spotting of the YES broth on TLC plates, some aflatoxin-producing strains were not detected.
