A nineteen-month-old child presented with a febrile illness, skin rash, painful swelling of the joints, lymphadenopathy and hepatosplenomegaly. Pseudomonas was cultured from the blood during life and, subsequently, at autopsy. Autopsy revealed a generalized panarteritis involving the coronary, retroperitoneal and pulmonary arteries with thickening of arterial walls and narrowing of the lumina. Thrombi and foci of necrosis and infarcts were found in many organs. Numerous bacilli were present in fresh lesions, but not in the organizing lesions. Periodic acid-Schiff-positive deposits were found in occasional macrophages, in walls of affected vessels, in the marginal sinuses of lymph nodes and diffusely in epicardial and retroperitoneal adipose tissue. The findings suggest that some or even all cases of Kawasaki's disease and infantile polyarteritis nodosa may be caused by Pseudomonas sepsis. It is also suggested that the vasculitis and paucity of inflammatory reaction in many cases of Pseudomonas sepsis might be related to the fact that many strains of Pseudomonas produce high-molecular-weight levan (or another polysaccharide). This compound is known to inhibit the inflammatory reaction and to increase bacterial pathogenicity.

Chronic neutrophilic leukemia is a rare, infrequently recognized, myeloproliferative disorder. It usually manifests as a leukemoid reaction, with mostly mature granulocytes in the peripheral blood, with rare to occasional immature forms, and sometimes with normoblasts. The clinical manifestations also include hepatosplenomegaly, elevated leukocytic alkaline phosphatase, elevated serum vitamin B12 and serum vitamin B12 binder ("R" fraction), and elevated serum uric acid. Distinction from a leukemegaly, the absence of sepsis, usually normal erythrocytic sedimentation, and the absence of fever. Leukemoid reactions may be associated with elevated serum vitamin B12 and uric acid, but the levels are usually lower than those found in chronic neutrophilic leukemia. Many patients have gouty symptoms, especially after treatment with Busulfan, and many have an unexplained hemorrhagic tendency, making major operations a risk. The authors add two cases to the 11 previously described.

An unusual syndrome of hepatosplenomegaly and fever followed by rapid deterioration and death has been described in 38 children from 21 families. Pancytopenia, liver dysfunction, and bleeding developed prior to death from hemorrhage, sepsis, or lymphocytic meningitis. This report reviews the literature and adds a set of twins to the reported cases.

Two cases of infantile osteopetrosis are reported. Both were males aged four and eight months at presentation. They presented with osteosclerotic change of the bone, leukoerythroblastic anemia, optic atrophy, hepatosplenomegaly and frequent infection. The histology of the bone showed thickened bone trabeculae with little osteoclastic activity, although in one patient the number of osteoclasts increased, while in the other they did not. One received a bone marrow transplant (BMT) but died from disseminated cytomegaloviral infection, pulmonary hemorrhage and sepsis. The post-transplant marrow histology showed evidence of engraftment and osteoclastic activity. The other only received a course of prednisolone, which was of little help. His condition has followed a natural course with progressive visual impairment and marrow failure. Our cases suggest that infantile osteopetrosis should be taken into consideration in dealing with infants who present with early marrow failure and that patients of infantile osteopetrosis should receive BMT. BMTs appear to be the only cure. They should be given as early as possible to avoid major consequences and severe infection.

We studied 12 children who presented with a recently recognized syndrome. The salient features of this new syndrome were recurrent fever; hepatosplenomegaly; pancytopenia; blond, golden to silvery gray hair; hypopigmented skin, progressive white matter demyelination; and early death. Seven patients died, four with severe central nervous system (CNS) involvement, and three with bone marrow failure and sepsis. Cutaneous anergy to recall antigens was present in all patients. Other immunological abnormalities were poor antibody responses; deficient T-cell responses to phytohemagglutinin (PHA), concanavalin A (Con-A), and allogeneic lymphocytes; hyperresponsiveness of B lymphocytes to pokeweed mitogen; and variable phagocytic defects. Histopathologic examination of the hair and skin biopsies showed characteristic distribution of melanin with melanocytes present in normal numbers but with fewer short dendritic processes. Langerhans' cells were present in normal numbers in some patients and sparse in others. This syndrome seems to cluster into two tribes from two different geographical areas in the Arabian Peninsula. In the eight families studied, 12 other siblings and close relatives were found to be affected. The mode of inheritance in this syndrome is that of an autosomal recessive pattern. We propose the term "PAID syndrome" to identify patients with the above features.

We describe two unusual cases of Epstein-Barr virus infection that were complicated by the virus-associated hemophagocytic syndrome, predominantly involving the spleen. Both patients were young adult men who presented with fever, pancytopenia, and hepatosplenomegaly. Both had prompt symptomatic and hematologic improvement following splenectomy. Severe constitutional symptoms recurred in one patient 1 month after splenectomy, and he died of septicemia 2 months later. In both cases, there was prominent hemophagocytosis in the splenic red pulp. Some hemophagocytosis was also noted in the liver from the fatal case. Unexpectedly, no hemophagocytosis was detected in the bone marrow biopsy specimens or marrow aspirates obtained from these patients. The DNA hybridization studies detected Epstein-Barr virus genomes in spleen samples from both patients, and both patients had atypical patterns of serologic response to the virus, suggesting that a defective immune response may lead to an unrestrained viral proliferation. We conclude that there is an association between chronic active Epstein-Barr virus infection and the hemophagocytic syndrome, but that the tissue distribution of the hemophagocytosis may be variable.

We reported 3 fatal cases of primary Epstein-Barr virus (EBV) infection resembling histiocytic medullary reticulosis (HMR) in young children in Taiwan, where an HMR-like illness has been previously found to be prevalent. The disease ran a fulminant course, manifesting as fever, anemia, jaundice, skin rash, pulmonary infiltration, and/or hepatosplenomegaly lasting for only 1-3 weeks. Laboratory tests revealed no hemolytic anemia and Coombs test was negative. Sepsis or HMR was the main clinical differential. At autopsy, the spleen, liver, lymph node, lung, and bone marrow showed infiltration of atypical "histiocytes" or blasts, lymphocytes, and mature histiocytes with hemophagocytosis. Immunophenotype and gene rearrangement studies of the lymphoid tissues revealed that these atypical "histiocytes" were actually polyclonal B immunoblasts in one case and transformed T lymphocytes in the remaining 2 cases, representing two different types of virus-host interaction. Southern blot and in situ hybridization studies on frozen lymphoid tissues demonstrated the presence of EBV DNA in all 3 patients; the study for cytomegalovirus was negative. The young age of these patients, closely correlated with the prevalent age of primary EBV infection in the general populations in Taiwan, strongly suggest that these childhood cases of previously diagnosed HMR-like disease may actually represent a lethal form of primary EBV infection or fatal infectious mononucleosis.

From 1982 to 1985, four cases of primary myelofibrosis were diagnosed in our department. Three were boys and one was a girl. Their ages ranged from 7 months to 15 years. The diagnosis was made based on anemia, leukoerythroblastic change and presence of giant platelets in the peripheral blood, and a bone marrow biopsy showing myelofibrosis. Most of them had anemia, fever, and hepatosplenomegaly on admission. The anemia was severe and refractory to repeated transfusions and steroid therapy in 3 out of the 4 cases. Splenectomy was performed in 1 case, but without satisfactory results. The clinical course and blood pictures in one case resembled leukemia of megakaryocyte lineage (M7), but results of marker studies of the blast cells ruled out the possibility of M7. Three of them underwent leukemic transformation within 2 years and died soon after. The other one died of sepsis 2 weeks after diagnosis. Myelofibrosis in childhood occurs rarely, however, when it does, it always runs a rapid and fatal course.

A guideline for early diagnosis of metabolic disorders affecting central nervous system during neonatal and early infancy was presented. Clinical manifestations associated with inborn errors of metabolism in the neonatal period are poor feeding, vomiting, diarrhea, abnormalities in muscle tonus, dyspnea, convulsion, coma and so on, and these are not specific to each disorder. However, such symptoms or signs as described below have often intimate relation to metabolic disorders: (1) previous children died of undetermined causes during early infancy; (2) complication of sepsis; (3) onset in the early neonatal period; (4) developmental and growth retardation. When newborns and infants have these symptoms or signs, we should start simple screening studies immediately for metabolic disorders, including CBC, hepatic function tests, blood glucose, lactate, pyruvate, ketone bodies, ammonia, blood gas analysis, urinalysis (including non-glucose reducing substance tests and FeCl3 reaction) and so on. As for CBC, we have to make our own effort to find spherocytosis and vacuoles in lymphocytes. Family history, especially the mother's personal history, is indispensable. During physical examinations, we must pay attention to facial appearance, skin color, macroglossia, hair abnormalities, peculiar odor of the urine and hepatosplenomegaly. When abnormality is found in these clinical signs or simple laboratory examinations, we should not hesitate to start dietary treatment even if special examinations for differential diagnosis are on the way.

A 52-year-old Japanese man manifested various clinical signs and symptoms such as vomiting, high fever, dyspnea, cough, sweating, palpitation, eosinophilic leukocytosis and hepatosplenomegaly. These histamine-related clinical manifestations showed a dramatic response to steroid therapy. After 10 months of hospitalization, he suddenly succumbed to candidal septicemia at the end of the third cycle of steroid therapy. Autopsy revealed neoplastic proliferation of immature basophils in various internal organs without involvement of the skin. The neoplastic cells, positive immunohistochemically for leukocyte common antigen, possessed lobulated nuclei and weakly metachromatic cytoplasmic granules, predominantly of the basophil type, which exhibited weak naphthol ASD-chloroacetate esterase activity. Mast cell-type granules were also observed ultrastructurally. The neoplastic infiltration was associated with fibrosis in the liver, spleen and bone marrow and with extramedullary hematopoiesis in the liver, spleen, lymph nodes and perihypophyseal tissue. The bone marrow showed uneven and multifocal involvement. Despite the lack of leukemic manifestations and the results of chromosomal analysis, the most suitable diagnosis was aleukemic basophilic leukemia within the category of chronic myeloproliferative disorder. Kinship of this neoplasia to systemic mastocytosis is discussed.
