A three-year-old boy has coarse facial features, upper respiratory congestion, profound mental retardation, hepatosplenomegaly, increased height and head circumference, cataracts, a gibbus deformity, radiographic changes of dysostosis multiplex, and vacuolized peripheral lymphocytes. These findings are the most commonly reported clinical features in the previously described patients with mannosidosis. Our patient has a severe deficiency, and his parents have intermediate levels, of the acidic component of alpha-mannosidase in their cultured fibroblasts.

The case history of a 9 months old infant with hepatosplenomegaly, pancytopnaenia and disturbances of clotting and cellular immune reactivity is reported. The spleen was removed and showed striking erythrophagocytosis by proliferating histiocytes, typical of "familial erythrophagocytic reticulosis" (Farquhar). A graft-versus-host reaction is discussed as a possible underlying cause. The favourable clinical course and full recovery point to an interrelation with primary hypersplenism.

Autoradiographic and liquid scintillation counting studies were made during the early graft-versus-host-reaction in mice. At the height of GVHR on the 10th day after transplantation, hepatosplenomegaly correlated with the radioactive disintegrations (DPM). This coincided with a high proliferation rate of the blasts that appeared in the spleen, and of the portal infiltrations and Kupffer cells in the liver. Convenient control groups were used to show that these changes are a specific reaction in GVHR.

Radiographically detectable complications in 35 children after bone marrow transplant are reviewed. These complications are most frequently due to infection, chemoradiotherapeutic toxicity, and graft versus host disease (a transplant rejection phenomenon peculiar to bone marrow transplant patients). The pulmonary complications within the first 2 months are secondary to a form of interstitial lung disease. Interstitial lung disease has a strong correlation with graft versus host disease. Extrapulmonary visceral complications include hepatosplenomegaly, nephromegaly, and hemorrhagic cystitis. These are due to graft versus host disease, radiation, and chemotherapeutic toxicities, respectively. Sinusitis, cerebral atrophy, and intracerebral hematomas are less frequent complications. Osteoporosis due to steroids is the single most important osseous complication.

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.

Of 18 boys in Duncan kindred, 6 died of a lymphoproliferative disease. They exhibited a subtle, progressive combined variable immunodeficiency disease characterised by benign or malignant proliferation of lymphocytes, histiocytosis, and alterations in concentrations of serum-immunoglobulins. Infectious mononucleosis occurred during or preceding terminal events in at least 3 of the cousins. Fever, pharyngitis, lymphadenomegaly, hepatosplenomegaly, atypical lymphocytosis, and a spectrum ranging from agammaglobulinaemia to polyclonal hyper-gammaglobulinaemia occurred. At necropsy, the thymus gland and thymic-dependent areas in the lymph-nodes and spleen were depleted of lymphocytes. Diffuse infiltrates composed of lymphocytes, plasma cells, and histiocytes, some containing erythrocytes, invaded the haematopoietic organs, viscera, and central nervous system. In addition, 2 half-brothers had lymphomas of the ileum and central nervous system. Approximately half the boys, including the half-brothers, were affected, and girls were spared, implying sex-linked recessive inheritance. Various lymphohistiocytoses resemble Duncan's disease, but it is distinctive from them in the mode of inheritance or by histiological characteristics. This study suggests that the Epstein-Barr virus or other viruses triggered the fatal proliferation of lymphocytes and that progressive attrition of T-cell functions allowed uncontrolled lymphoproliferation.

An immature neonate surviving for 45 minutes showed a generalized hydrops and hepatosplenomegaly unassociated with blood incompatibility. A marked activation of extramedullary haematopoiesis was observed not only in its liver and spleen, but also in the interstitium of the lungs, pancreas, kidneys, and adrenal glands. In addition, extensive necrosis of the brain and diffuse nonsuppurative myositis and myocarditis were found. All the changes were due to congenital toxoplasmosis, which has been confrimed by the findings of occasional pseudocysts within the placenta, by the result of the parasitologic examination of the brain of the autopsied infant and by serological examination of the mother post partum.

A diagnosis of Niemann-Pick disease type A was made in a 6-month-old boy on the grounds of progressive psychomotor retardation, hepatosplenomegaly, typical foam cells in the bone marrow and a deficiency of sphingomyelinase in a liver biopsy. Typical ultrastructural changes in lysosomes were found in hepatocytes and in Schwann cells. In spite of the absence of gross morphological changes in the axons and in the myelin sheath of the peripheral nerve biopsy, the nerve conduction velocity in the patient was greatly reduced. The ultrastructural aspect of the lysosomal inclusion suggested the storage of a phospholipid. Biochemical analysis of the liver biopsy demonstrated an increased content of total phospholipid of which sphingomyelin made up for more than 60%. The significance of these data are discussed.

Histiocytic medullary reticulosis (HMR) is a rare, progressive, fatal reticuleondothelial proliferative disorder. It was diagnosed in a 10-year-old boy who had pityriasis lichenoides et varioliformis acuta of Mucha-Haberman which was controlled by dapsone for 2 years. One month after cessation of dapsone therapy, cutaneous tumors associated with fever, lymphadenopathy, and hepatosplenomegaly developed. Tissue biopsy specimens of skin, liver, spleen, lymph nodes, and a bone marrow aspirate demonstrated histiocytic erythrophagocytosis and atypical histiocytosis compatible with HMR. A rapidly progressing, fatal course followed despite intensive chemotherapy.

Circulating antibodies against certain nuclear acidic protein antigens have been shown to have diagnostic and prognostic importance in connective tissue disease. We describe a new precipitin system found in the sera of patients with systemic lupus erythematosus. The antigen, called MA, was prepared from calf thymus nuclei, and was shown to be distinct from other nuclear acidic protein antigens by physicochemical and immunologic techniques. MA antibodies were detected in the serum of 12 of 66 lupus patients and in none of 554 sera from normal controls or patients with other rheumatic diseases. Lupus patients having MA antibodies had more severe disease than did lupus patients with Sm or native DNA antibodies, manifested by recalcitrant skin rashes and a significantly greater incidence of hypocomplementemia, serious renal disease, hypertension, hepatosplenomegaly, lymphadenopathy, and neurological disease (P values range from 0.025 to 0.005). The presence of circulating MA antigen was demonstrated in three lupus patients immediately before a flare of nephritis. These data suggest that MA is a nuclear acidic protein antigen that may identify a subset of lupus patients with very severe disease. The presence of the antigen in the circulation before clinical flares suggests a possible biologic role for the MA system in an immune complex nephritis.
