A case of the syndrome of sea-blue histiocyte is presented in a 53-year-old Japanese woman, which is the first recorded case in Japan. The patient had
hepatosplenomegaly
, bleeding manifestations, mild thrombocytopenia, fatty metamorphosis and cirrhosis of the liver, as well as abnormal serum lipid profiles. Her parents were consanguineous and her maternal grandmother with
hepatomegaly
died of hepatic failure. Histologically, peculiar histiocytes containing numerous, intracytoplasmic sea-blue stained granules on May-Giemsa stain were demonstrated in biopsy materials of the bone marrow, lymph node and liver. The sea-blue granules in these histiocytes proved to have histochemical staining characteristics of lipogenic ceroid-like pigment. Ultrastructurally, these granules showed membrane-bound, pleomorphic inclusions of heterogeneous nature, including electron-dense amorphous or variegatedly osmiophilic, frequently laminated materials. Enzyme cytochemically, localization of acid phosphatase activity was demonstrated in and around the intracytoplasmic inclusions. With regard to the pathogenesis of the sea-blue histiocytes in this case, it may be suggested that the existence of the abnormality in lipid metabolism plays an important role in intralysosomal ceroidogenesis in these histiocytes.

Specific IgM and IgG antibody to a polysaccharide present in the epithelial cells of the gut of adult schistosomes was measured in four groups of infected patients: I) patients with documented acute schistosomiasis; II) Americans exposed to schistosomiasis within the preceding 0--4 years; III) chronically and heavily infected patients, mostly from Puerto Rico, without
hepatomegaly
or
hepatosplenomegaly
; and IV) heavily infected Brazilian children with hepatic or hepatosplenic schistosomiasis. Specific IgM and IgG titers were both highest in the acute Group I patients and lowest in the chronically infected Groups III and IV. Total IgG and IgM levels were compared to specific antibody titers. Immunoglobulin levels tended to follow specific antibody titers except in the chronically infected Groups III and IV in which total IgG rose to high levels. The decrease in specific antigen titers over the course of time occurred despite continued antigenic stimulation and suggests a modulation of the humoral response. The mechanism remains obscure.

Seventy children with
hepatomegaly
, between the ages of 3 months and 13 years, were investigated including a liver biopsy in 60, to study the general pattern of liver disease in children. Thirty percent had acute viral hapatitis, 20 percent cirrhosis, 17.6 percent pulmonary tuberculosis, 18 percent hereditary diseases and 14 percent miscellaneous diseases involving the liver. None of the cases met the criteria for Indian childhood cirrhosis. It was concluded that in Karachi pulmonary tuberculosis was a common case of
hepatosplenomegaly
in children and that the aetiology of cirrhosis was probably multifactorial.

In schistosomiasis mansoni, the pathogenesis of hepatosplenic disease has been shown to be due primarily to immune mechanisms. The present study was designed to examine the relationship between the development of schistosomal
hepatosplenomegaly
in Egyptian school children and the HLA antigens. Two groups of schistosome-infected children with similar fecal egg counts were examined: one group (23 children) had no clinically demonstrable
hepatosplenomegaly
whereas all the children (28) in the second group suffered from liver enlargement. Furthermore, 13 of the 28 individuals in the latter group had splenomegaly as well. Our results show that
hepatosplenomegaly
was related to the presence of two HLA antigens: HLA AI and B5. The average relative risk of developing
hepatomegaly
is 29 for HLA AI and 18.9 for 55.6. Furthermore, the severity of
hepatomegaly
was correlated with the presence of these two HLA antigens. These findings represent a step toward elucidating the factors controlling the pathogenic mechanisms in human schistosomiasis mansoni.

The Budd-Chiari syndrome caused by occlusion of the major hepatic veins, often of unknown etiology, is typically characterized by massive ascites,
hepatomegaly
and abdominal pain due to intense congestion of the liver. The outcome has almost always been fatal. This report describes an evaluation of side-to-side portacaval shunt in dogs with experimental Budd-Chiari syndrome and in six patients with hepatic vein thrombosis. In the animal studies, side-to-side portacaval shunt was very effective in relieving massive ascites,
hepatomegaly
, hepatic congestion and portal hypertension produced by ligation of the hepatic veins. Only one of 24 dogs with side-to-side anastomosis reformed ascites, 67% of the animals survived until the study was concluded after one year, and liver biopsies showed reversal of the severe pathologic abnormalities. In contrast, all 20 control dogs subjected to a sham laparotomy, and all 20 dogs that underwent end-to-side portacaval shunt reformed massive ascites and died within six months with continued hepatic congestion and necrosis. All six patients with the Budd-Chiari syndrome due to hepatic vein occlusion had massive ascites (4.4-15.9 l),
hepatomegaly
, abdominal pain and disturbed liver function. In all six, angiography demonstrated occlusion of the hepatic veins with a patent inferior vena cava (IVC) and a normal IVC pressure, and liver biopsy showed intense centrilobular congestion and necrosis. The most valuable diagnostic study was angiography of the IVC and hepatic veins with pressure measurements. Side-to-side portacaval shunt was performed from four to 14 weeks after the onset of symptoms, and produced dramatic and sustained relief of ascites in five of the six patients during follow-up periods of from eight months to seven years. Liver function returned to normal,
hepatosplenomegaly
disappeared, none of the survivors developed portal-systemic encephalopathy, and follow-up liver biopsies showed disappearance of congestion and necrosis, but mild to moderate fibrosis. One patient died following an emergency IVC thrombectomy and portacaval shunt, which was undertaken when, during the course of his workup, his condition deteriorated suddenly because the thrombotic process extended from the hepatic veins into the IVC. The everpresent risk of this complication, and the dangers associated with delaying operation were emphasized by this case. It is concluded that side-to-side portacaval shunt, which decompresses the liver by converting the portal vein into an outflow tract, provides effective treatment of the Budd-Chiari syndrome when the occlusive process is confined to the hepatic veins.

Brucellosis has always been an unusual disease in children and, concomitant with the control of the disease in domestic animals, reports have become sparse. The pediatrician, therefore, may not be aware of the protean clinical manifestations of childhood brucellosis. In 1973, nine cases occurred during a three-month period in El Paso, Texas. All cases were marked by spiking fevers and lethargy of four days to four weeks in duration. Tender
hepatomegaly
or splenomegaly was striking in seven patients. Other characteristics included epistaxis, arthralgia, myalgia, and weight loss. Leukopenia and leukemoid reaction were found in five patients. All of the patients tested had elevated liver enzymes. Febrile agglutinins were invaluable in screening for an early clue to diagnosis. When Brucella abortus antigen agglutinated serum from patients with a positive screen in dilutions greater than 1:320, a presumptive diagnosis of brucellosis was made. Brucella was isolated from the blood or bone marrow in seven patients and the time of incubation proved crucial for successful recovery. Bacterial blood cultures are usually discarded at ten days of age, as were cultures from the only two patients from whom the organism was not recovered. All of the cultures incubated for 12 to 15 days grew B. melitensis, an unusual causative species in the United States. However, several patients admitted eating cheese from the State of Chihuahua, Mexico, made from unpasteurized goat's milk, the presumed source of the infection. Within one to three days, all patients responded dramatically to antibiotics; tetracycline was given orally for 21 days and streptomycin intramuscularly for 14 days. Pediatricians caring for patients in areas where consumption of unpasteurized milk products is likely would do well to consider brucellosis in a child with obscure fever or toxic
hepatosplenomegaly
.

Mucopolysaccharidoses (MPS) are inherited disorders of lysosomal enzymes. We have examined the sites of accumulation of intravenously injected 99mTc-sulfur colloid in order to assess the regional distribution of phagocytic function in ten patients with MPS: three with Type VI (Maroteaux-Lamy). Increased lung uptake was observed in 22 of 40 studies (55%) on the five patients with MPZ Type II but in none of the 38 studies on patients with other MPS types. All MPS patients had diffuse recticuloendothelial (RE) marrow hypoplasia, despite normal or nearly normal hematocrits and hemoglobin levels, suggestion dissociation of the phagocytic and erythropoietic elements of the marrow. The eight patients with MPZ Types I and II all had
hepatomegaly
and increased splenic uptake. Seven of these patients with MPS Types III and VI did not have
hepatosplenomegaly
. These studies indicate that the lysosoma enzymic defect of MPS results in widespread abnormalities of the distribution of phagocytic function in the liver, spleen, bone marrow, and probably the lung as well.

Twenty-six cases of histologically proven malignant histiocytosis are presented. Patient ages ranged from 20 months to 82 years, and a 10:3 male preponderance was seen. Clinical presentation is similar to that of malignant lymphoma and leukemia; histologic differentiation is required. The frequency of intrathoracic involvement at the time of presentation is similar to that of non-Hodgkin's lymphoma. Retroperitoneal lymph node invasion was readily seen on five of the eight lymphograms performed.
Hepatosplenomegaly
was a common finding, and three of the patients had evidence of bone involvement during the course of their illness. While there are no radiographic findings specific to malignant histiocytosis, the presence of
hepatomegaly
should suggest this possibility. The establishment of the correct diagnosis is important to guide choices in chemotherapy.

Physicians examined the records of 47 adults with visceral leishmaniasis (VL) and HIV-1 infection who were patients at 3 urban teaching hospitals in the Andalucia region in southern Spain between January 1986 and November 1991. They wanted to identify the clinical, biological, and epidemiological features of VL in HIV-1 positive patients. 96% of the cases were diagnosed with both infections during the last 2 years of the study period and 79% between January and November 1991. All the patients had risk factors for HIV infection (65.9% IV drug use, 21.3% sexual contact, and 12.8% blood transfusion). 70% exhibited the classic symptoms of VL (fever,
enlarged liver
and spleen, and depressed counts of blood cells). Most patients were already very immunocompromised when VL was diagnosed. 87% had a total lymphocyte count of less than 1000 x 1 million/1 and a CD4 lymphocyte count of less than 200 x 1 million/1. In fact, 66% had full blown AIDS prior to diagnosis of VL. VL was the first severe infection in 10 cases. 68% also suffered from opportunistic infections, especially candidiasis, extrapulmonary tuberculosis, and Pneumocystis carinii pneumonia. Microscopic examination of Leishmania amastiogotes in tissue samples led to a diagnosis in 94% of cases, isolation of motile amastigotes in culture of bone marrow aspirate in 2%, and microscopic and culture in 4%. Just 46% completed a full course of treatment (pentavalent antimony, allopurinol, and/or pentamidine). Only 38% had a microbiological response. Immunofluorescence detected sizeable titers (1:40) of antileishmanial antibodies in just 31% of cases. 17% experienced clear clinical improvement. Physicians in endemic areas should consider VL in every HIV-1 infected patient with fever,
hepatosplenomegaly
, or hematological abnormalities to avoid underdiagnosis of leishmaniasis.

The children of 50 women positive for antibody to human immunodeficiency virus type 1 (HIV-1) and 42 children of antibody-negative mothers were examined for lymphadenopathy and
hepatosplenomegaly
at 3-month intervals during the 1st year of life. Lymphadenopathy was found to be significantly more frequent at 6 months (p less than 0.01), 9 months (p less than 0.001) and 12 months (p less than 0.01) in children who were subsequently shown to be infected with HIV-1.
Hepatomegaly
was seen more frequently (p less than 0.05) in the 1st year in HIV-1-infected children than in uninfected children. Splenomegaly was not more frequent in HIV-1-infected children in this area which is holoendemic for falciparum malaria.
