A 54 year old man, hospitalised for thoraco-abdominal pain resulting from a septicemia which gives positive hemocultures for streptococcus D Bovis, is diagnosed to have a splenic abscess which will require splenectomy. At the same time, an endocarditis develops and gets worse, with auriculo-ventricular blockade and, especially, major aortic insufficiency, which is the cause of death by a brutal and massive pulmonary oedema. In the progression of an endocarditis, the occurrence of a splenic abscess, primary localisation of the initial septicemia or the secondary of an arterial septic embolism, is a rare contingency compared to the frequency of splenomegaly or splenic infarction: less than 2 percent of the cases in the literature. This very atypical and exceptional case serves as a reminder, on the one hand, of the diagnostic inadequacy of echocardiography which cannot visualise vegetation in the course of progressive endocarditis, and, on the other, of the prognostic importance of auriculoventricular blockade in septal and aortic endocardial lesions.

A 35-yr-old man with moderate hypertriglyceridemia, associated with a positive family history for hyperlipidemia, developed chylomicronemia with abdominal pain, muscle pain, and splenomegaly while being treated with cimetidine for a duodenal ulcer. The chylomicronemia and the pain subsided after the drug was stopped. When the patient was rechallenged with the drug 6 mo later, the chylomicronemia reappeared after a treatment period of 6 days. Chylomicronemia and its complications should therefore be considered as a potential risk when cimetidine is prescribed to patients with known hyperlipidemia.

An 8-year-old boy developed anaphylaxis after receiving his maintenance dose of immunotherapy and proceeded to display the signs and symptoms of serum sickness. These consisted of fever, arthralgia, arthritis, urticaria followed by a hemorrhagic palpable rash, edema, lymphadenopathy, splenomegaly, abdominal pain, proteinuria, and neurologic manifestations consistent with vascular compromise of the posterior cerebral circulation. A skin biopsy specimen revealed perivascular infiltrates of lymphocytes and few polymorphonuclear neutrophils. The timing of events in this patient suggests that immunotherapy initiated a chain of events beginning with anaphylaxis and leading to serum sickness. It is hypothesized that the enhanced vascular permeability that accompanied the anaphylaxis allowed immune complexes that may have preexisted in the circulation to deposit in the blood vessels of the patient. These complexes may or may not have been related to the immunotherapy itself. Because antihistamines are known to prevent the induction of serum sickness, early and aggressive treatment of anaphylaxis during immunotherapy may prevent the occurrence of immune complex disease.

Investigations of schistosomiasis mansoni in 218 Yemeni agricultural workers in the San Joaquin Valley of California revealed a prevalence of 56%. In those infected, quantitative egg counts performed by the Kato thick smear method revealed that 57% had light infections (1-100 eggs/g), 27% moderate infections (101-400 eggs/g), and 16% heavy infections (greater than 400 eggs/g; mean--918 eggs/g). The Yemeni had been migrating to the USA for the past 20 years, a period in which the prevalence of schistosomiasis had remained constant in the Yemen. The prevalence of schistosomiasis in those who had been away from Yemen for less than 5 years was 59% with a mean egg output of 236 eggs/g, but in those away for more than 5 years (up to 20 years) it was 32% with a mean egg output of 75% eggs/g. This is in spite of the fact that 75% of the latter had returned to Yemen for short visits. Statistical analysis by the Fisher's exact probability test revealed a significantly lower egg output in those away from Yemen more than 5 years. On the basis of these findings the mean life span of the Yemen strain of Schistosoma mansoni in man was estimated to be between 5 and 10 years. The presence of disease was assessed in this population by traditional medical means without prior knowledge of the status of the infection in the individuals examined. Under these circumstances, there were no differences in symptoms such as weakness, diarrhea and abdominal pain among the uninfected proportion of the population, total infected group and a small subgroup of those most heavily infected. None of the patients had hepatomegaly and only two had splenomegaly--one lightly and the other heavily infected. Because of the toxicity of antischistosomal drugs and the lack of treatment facilities only the 22 most heavily infected (greater than 200 eggs/g) of the 122 individuals with schistosomiasis mansoni were treated with niridazole. In addition the two individuals with splenomegaly were treated with antimony dimercaptosuccinate. Side effects, though common, were not severe. Although follow-up in this migrant population was poor the nine patients examined 3 to 7 months after treatment showed a mean decrease in egg output of 97%.

The indications and management of blood transfusion in the haemoglobinopathies have been reviewed. The sickle cell diseases that require transfusion support are sickle cell anaemia, sickle haemoglobin-C and -D diseases and sickle beta-thalassaemia. Homozygous beta-thalassaemia (Cooley's anaemia) is the major problem among the thalassaemias. The pathophysiology of the sickle cell disorders is largely based on the secondary effects of increased blood viscosity, whereas in the thalassaemias the defect is ineffective haematopoiesis. In the former the major problems occur as manifestations of vaso-occlusive crises with disseminated bone and abdominal pain, priapism, stroke and leg ulcers. Bone infarction and aseptic necrosis occur but the widespread bone changes, underdevelopment and haemochromatosis that complicate the thalassaemia are not prominent. Transfusion therapy in the sickle cell diseases is mainly episodic and is guided by the frequency of crises and the severity of vaso-occlusive complications. Partial exchange transfusion and the maintenance of haemoglobin A concentrations at 40 to 50 per cent is frequently indicated. In the thalassaemias, maintenance of haemoglobin levels is essential for normal growth and development. The problem of haemochromatosis is very serious. With hypertransfusion regimens the haemoglobin and haemotocrit are maintained above 12-13 g/dl and 35 per cent. The resulting benefit appears to be reduced blood volume, less iron turnover, and less intestinal iron absorption. The splenomegaly in these disorders is frequently associated with hypersplenism requiring well-timed splenectomy. Chronic and intensive chelation is necessary to prevent the ravages of iron overload. The availability of automated equipment for in vivo and ex vivo blood cell separation has brought new possibilities for improving the management of these haemoglobinopathies. It is feasible, but not as yet practical, to offer transfusions of neocytes (red cells with a mean age of 30 days) which have a 50 per cent longer survival than routine red cell preparations (mean age of 60 days). Neocytes can be prepared ex vivo from fresh routine blood donations using blood cell separator devices. The result is reduced transfusion requirements. A more recent suggestion for using the new technology is to remove the patient's oldest and most abnormal corpuscles on the basis of buoyant density and replacing them with neocytes . Thus the short-lived abnormal red cells would be removed before they could unload their iron. With automation it is possible to perform these procedures on an outpatient basis.

Nineteen patients with fungal splenic abscesses included 16 with leukemia, one drug user, one patient with Cushing's syndrome, and one without predisposing causes. Fifteen had persistent fever; six had esophageal or mucocutaneous candidiasis. Abdominal pain occurred in seven patients, splenomegaly occurred in six, and left abdominal mass occurred in one. Three chest x-ray films showed left pleural effusions; two had elevated left hemidiaphragms, two had left-sided infiltrates, and one was normal. Sixteen of 17 technetium Tc 99m sulfur colloid scans were abnormal, as were 15 gallium citrate Ga 67 scans. Two computed tomographic studies revealed splenic defects. Candida was the cause in 15 cases, Aspergillus was the cause in three cases, and Blastomyces dermatitidis was the cause in one case. Sixteen patients underwent splenectomy, 12 receiving postoperative antifungal therapy. Fifteen survived regardless of underlying disease or hepatic microabscesses.

A new case of C-II anapolipoproteinemia (complete apolipoprotein C-II deficiency) as the cause of severe hypertriglyceridemia with chylomicronemia (type I lipoprotein phenotype) is described. The patient was a five-year-old boy living in Connecticut. He had splenomegaly, episodic abdominal pain, and bloody stools. Absence of apolipoprotein C-II (and its isoforms C-II1 and C-II2) was documented by a sensitive and specific radioimmunoassay, analytical isoelectric focusing, and in vitro lipolytic assay. Decreased levels of high- and low-density lipoprotein cholesterol and apolipoproteins A-I and A-II and increased levels of plasma triglycerides and apolipoprotein E were found. Post-heparin extra-hepatic lipoprotein lipase activity was within normal range. Incorporation of exogenous purified human apolipoprotein C-II to an incubation mixture of purified lipoprotein lipase and the patient's triglyceride-rich lipoproteins resulted in a dramatic increase in the catabolic rate of the defective triglyceride-rich lipoproteins. The absence of the isoforms of apolipoprotein C-II in this patient indicates that a common gene exists for the C-II isoproteins, which appear to be necessary for normal triglyceride transport in humans. A literature review of 23 reported cases indicates that xanthomas and hepatosplenomegaly are less common in C-II anapolipoproteinemia than in lipoprotein lipase deficiency, the other major etiologic cause of genetic chylomicronemia.

Eighty-four cases of schistosomiasis mekongi among Cambodian refugees in holding centres in Thailand received praziquantel at 30 mg/kg body-weight orally twice in one day. Those treated were admitted to hospital in order to observe side effects for 24 hours. Assessment of the efficacy of praziquantel was based on cure rates. Side effects observed consisted primarily of abdominal pain, anorexia, nausea, emesis and headache. These were generally mild and transient. Physical signs revealed mild hepatomegaly and splenomegaly. The cure rate obtained one month after treatment was 97.5% and by 2 to 12 months after treatment reached 100%.

The clinical, laboratory, and scintigraphic findings in four cases of human fascioliasis are described. Acute onset of fever, abdominal pain, and weight loss in a person who has ingested watercress constitutes the clinical syndrome often seen. Eosinophilia and alteration in liver function tests, particularly alkaline phosphatase are frequent. Tc-99m sulfur colloid images showed hepatomegaly in four patients, focal defects in two, splenomegaly in three, and increased splenic uptake in two. Gallium citrate (Ga 67) images show increased uptake in the focal lesions in two of two. Sonographic imaging showed focal lucent abnormality in one of three. Liver biopsy findings were nonspecific. The differential diagnosis from other invasive parasitic diseases is discussed. A possible role of hepatic imaging in the evaluation of fascioliasis is suggested.

The spleen was assessed in 10 patients with sickle cell disease studied with computed tomography (CT) for abdominal pain and/or unexplained fever. Patients with homozygous sickle cell anemia were found to have small, densely calcified spleens with occasional low-density infarcts. Five of six had hepatomegaly, and there was one case each of hepatic abscess, infarcts, and hemochromatosis. All patients with heterozygous sickle cell disease were found to have splenomegaly, with a variety of findings including acute hemorrhage, acute and chronic infarcts, rupture, and possible sequestration. It was concluded that CT is useful for evaluating the status of the spleen and liver in symptomatic patients with sickle cell disease.
