Four groups of 6 pigs each were given 5 x 10(5) to 3 x 10(6) sporocysts of a Georgia isolate of Sarcocystis suicanis. Only the 6 pigs given 3 x 10(6) sporocysts became acutely ill at postinoculation days (PID) 12 to 15, and 3 of the 6 diet at PIG 14 or 15. Clinical signs included purpura of the skin of the ear, snout, and buttocks and dyspnea, muscle tremors, and severe locomotor difficulties. Clinical abnormalities were accompanied by laboratory findings of pyrexia, severe anemia, leukopenia, thrombocytopenia, megathrombocytosis, prolonged prothrombin time and activated partial thromboplastin time, and hypofibrinogenemia. Seemingly, excessive intravascular coagulation may be involved in the pathogenesis of this disease in swine. Pigs given 5 x 10(5) to 1 x 10(6) sporocysts did not exhibit clinical signs; however, leukopenia and thrombocytopenia were demonstrated in the pigs at all dosage levels. Growth rates were impaired in surviving pigs. Second-generation schizonts containing merozoites were found in vascular endothelium of pigs dying on PID 14 or 15. Nonsuppurative myocarditis and hepatitis were present. Numerous developing cysts were in the musculature of pigs enthanatized on PIG 35 to 52. Cyst dissolution and resorption occurred concomitantly, indicating that swine may be able to clear the infection.

Ulcerative hemorrhagic enteritis of swans induced by Sphaeridiotrema globulus is enzootic at Lake Musconetcong in northern New Jersey. It accounted for a calculated 250 deaths of wild mute swans (Cygnus olor) between 1970 and 1980. The swans died primarily in the winter and early spring. Sites of infection included the jejunum and ileum. Trematodes singly or in groups ulcerated the intestines. Severe hemorrhage from damaged submucosal capillaries provided a blood meal for the parasites and probably precipitated the anemia observed. The intensity of fatal infections ranged from 20 to 870 parasites. A mononuclear periportal hepatitis and secondary nodules in the spleen were commonly observed. Affected swans exhibited muscular weakness and appeared to have died from hypovolemic shock or some complication associated with it.

More than 0.5 million refugees from Southeast Asia have immigrated to the United States. We undertook a prospective evaluation of 709 refugees within two months of their resettlement in San Diego. The sample included 164 Vietnamese, 356 Cambodians, 139 Laotians, and 50 Hmong. The prevalence of abnormalities was high: intestinal parasites, 61%; positive tuberculin test (PPD) results 55%; anemia, 37%; hepatitis B antigenemia, 14%; and abnormal VDRL test results, 12%. Except for hepatitis, significant differences were noted among the Vietnamese, Cambodian, Laotian, and Hmong subjects on each of these health status indicators. The refugee population should not be considered a homogeneous group of Indochinese, particularly by those responsible for their health care.

A 45-year-old woman who had undergone bilateral nephrectomy and splenectomy and who had been under haemodialysis since 1966 developed non-A non-B cytolytic hepatitis in October, 1978. Her haematocrit and haemoglobin levels had been stable at 39% and 6 g/dl respectively for more than one year when, two months after the onset of hepatitis, spontaneous improvement of anaemia was observed. This persisted side-by-side with hepatic cytolysis until march, 1980. At that time, the total red cell volume was 24% above normal, the haematocrit was 41% and the haemoglobin level 13 g/dl. It was than that serum erythropoietin was measured and found to be 82 mU/ml (normal values : 5-10 mU/ml). During the following months hepatic cytolysis and polycythaemia gradually subsided, and the serum erythropoietin level decreased. This case suggests that extrarenal erythropoietin can be secreted by the liver in anephric adults with uraemia, that hepatocytes undergoing regeneration after cytolysis in adults may have the same capability or erythropoietin secretion as in foetuses, and that in some haemodialyzed patients bone marrow responses to erythropoietin remains unaltered.

Loggerhead sea turtles (Caretta caretta) from the Atlantic seaboard (Florida to Massachusetts) were examined at the Marine Pathology Laboratory, University of Rhode Island, from March through December, 1980. Three genera of blood flukes (spirorchids) were found in 14 (33%) of the 43 turtles. Gross signs in heavily infected animals included cachexia, anemia and enteritis. Histopathological lesions were similar to those present in homeotherms with schistosomiasis. Granulomatous gastritis, enteritis, hepatitis, pneumonitis, and nephritis were present. Acute and chronic vasculitis accompanied metastasis of eggs. Infected animals had severe hepatic hemosiderosis, indicative of the anemia observed grossly. Evidence is presented that spirorchidiasis is prevelent in sub-adult loggerhead sea turtles, is responsible for extensive lesions and may be responsible for significant debilitation and mortality.

One hundred and twenty-five children with chronic liver disease were seen in Pune in 13 months. Fifty-nine of them, aged 8-39 months, had Indian childhood cirrhosis histologically diagnosed. Their characteristics included an insidious onset of symptoms, a geographical clustering of cases in rural areas north-east of Pune, a high rate of parental consanguinity and affected siblings, and a very high hepatic copper concentration (790-6654 micrograms/g dry weight). Only 8 survived for 6 months, adverse prognostic features being jaundice, ascites, enlargement of the gall bladder, and severe anaemia at presentation. Clinical differentiation from other liver disorders in the same age group was clear in advanced cases but unreliable in earlier cases. Four asymptomatic siblings with hepatomegaly had a benign course. The need for non-invasive methods to diagnose early cases in the community is demonstrated. The other major diagnostic categories were: unresolved hepatitis (12); chronic active hepatitis (7); cryptogenic cirrhosis (6); neonatal hepatitis and biliary atresia (8).

General principles for application of red blood cells depend on the amount of blood loss, on the oxygen-transport capacity, on the function of the transfused red cells and on the risks of blood transfusion. As a rule of thumb in acute blood loss red cells are wanted if the haemoglobin falls below 10 g/dl or the haematocrit below 30% and are urgently necessary if the haemoglobin falls below 8 g/dl and the haematocrit below 25%. In chronic normovolemic anaemia the indication for red cells is completely different. In the praeoperative state erythrocytes are given below 9 to 10 g/dl haemoglobin. Advantages and disadvantages of the different red cell preparations are discussed as follows: Whole blood is only indicated as fresh blood. Fresh blood stored not longer than 12 hours is only indicated in massive blood transfusion and in acute blood loss due to not yet cleared up haemorrhagic diatheses. A partial deplasmatized blood can be safely given instead of whle blood. Packed red cells not washed show a smaller volume risk and decrease the frequency of non-haemocytic transfusion reactons. The saline washed red cell concentrate does not reduce the frequency of alloimmunisation against tissue antigens, a decrease of the risk of hepatitis-B is questionable. The indication for washed red cells are to be found in febrile transfusion reactions due to leukocyte and platelet antibodies and in the transfusion preparation of dialysis patients. Leucocyte poor red cell concentrates can be prepared practically on by mechanically taking away the buffy coat. The frequency of alloimmunisation can be lowered down to 4% by this red cell preparation. The most expensive way of deep freezing red cells has its own indications. A decrease of hepatitis-B risk is present, hepatitis-B on the other hand cannot be safely avoided by using deeply frozen and thawed red cells.

Maternal mortality was examined in a semi-urban Nigerian community over a 10-year period. Maternal mortality was defined as death occurring as the direct result of childbearing and measured per 1000 births. Abortions at below 20 weeks gestation were excluded. From 1966 to 1975, there were 90 maternal deaths out of 13,182, a rate of 6.8/1000. The hospital records of the Baptist Medical Center, located in the western part of Nigeria, were carefully reviewed and cross-checked with obstetric statistical records. Only 13 of the deaths occurred in hospitalized patients. 78 (80%) were due to direct obstetric causes; 12% were from nonobstetric causes. Anemia due to blood loss was the leading casue of death, accounting for 30, or 33%, of the deaths. Anemia, with or without congestive heart failure accounted for 7 deaths. Infection was responsible for 5 deaths. Ruptured uterus, preeclampsia, and eclampsia occurred in equal percentages, 10-11%. Indirect obstetric deaths, such as sudden death, accounted for 10 deaths. 50% of these were anesthetic deaths; the remainder were due to pulmonary embolism. Sickle cell intrapartum crisis was the cause of 1 death. Associated causes included featured pneumonia, nephritis, hepatitis, meningitis, enteritis, and cerebrovascular accident. Parity ranged from 0-11. 25 babies were salvaged in this series. Prevention continues to be the cornerstone in improving maternal mortality figures in developing countries. The Baptist Medical Center's model for providing maternal care is described briefly and is identified as responsible for the encouraging decline in the maternal mortality rate.

This study was designed to investigate the usefulness of serum ferritin determinations for the diagnosis of cervical squamous cell carcinoma. The origin of ferritin in the circulation of these patients was also studied by an in vitro incubation system. Ferritin levels were determined by a radioimmunoassay kit (SPAC kit, Daiichi Radioisotope Lab.). Pretreatment serum ferritin levels were significantly higher (p less than 0.05) in patients with cervical squamous cell carcinoma, ovarian carcinoma, hepatitis and anemia than in normal women. All cases with endometrian cancer showed normal ferritin levels. Among patients with cervical squamous cell carcinoma, stage IV and recurrence groups showed higher ferritin levels than other stages. In vitro incubation studies revealed that squamous cell carcinoma could release significantly larger amount of ferritin than normal squamous epithelium. In addition, circulating and tissue ferritin of squamous cell carcinoma had the same immunological behavior in a ferritin radioimmunoassay, and also showed the identical localization on isoelectrofocusing gels. These results indicated that (1) circulating ferritin in patients with squamous cell carcinoma would, at least in part, be derived from the tumor tissue, and (2) serum ferritin determinations would be useful for the management of patients with cervical squamous cell carcinoma.

A patient with leukemic reticuloendotheliosis had splenomegaly, neutropenia, and a severe underproduction anemia. During a three-year period, the hematocrit was never in the normal range, and periodic transfusions were required. However, after an episode of hepatitis that was positive for B surface antigen, the spleen became smaller, the number of neutrophils increased, the transfusion requirement disappeared, and the hematocrit rose to normal. Several mechanisms for this observation are proposed.
