With the passive hemagglutination method the authors proved antibodies against milkprotein fractions in three of nine patients with hypochrome anemia aged 7, 12 and 17 months. In these children the X-ray examination showed an intestinal allergy, presumably the reason for occult intestinal bleeding which inturn caused hypochrome anemia. After milk was eliminated from the diet iron therapy restored a normal haemoglobin content. Iron therapy alone only improved the anemia, since continuing intestinal bleeding prevented fullrecovery.

Angiodysplasias of the colon are rare causes of intestinal bleeding. Diagnosis is by angiography or colonoscopy. In 6 patients with severe anemia in whom conventional methods had failed to reveal the source of bleeding, colonoscopy demonstrated angiodysplasias in the cecum or ascending colon. They were treated endoscopically. In a follow-up period of 3 months to 4 years only 1 patient has sometimes suffered occult fecal blood loss, but is adequately treated by oral iron therapy. No patient has had a severe recurrence of bleeding, nor was colonic resection necessary. It is concluded that endoscopic therapy of angiodysplasias is a valuable alternative to surgery with low risk and high efficiency.

Malignant tumors of the small bowel are rare but carry a grave prognosis. Thirty-seven cases from the Tumor Registries of Brooke Army Medical Center. Fort Sam Houston, Texas, and Fitzsimons Army Medical Center, Denver, Colorado, were retrospectively studied. Twenty-nine males and eight females ranging from five to 86 years were included in the combined series. Thirteen carcinoid tumors, eight adenocarcinomas, seven lymphosarcomas, five leiomyosarcomas, two reticulum cell sarcomas, one liposarcoma, and one mesenchymal cell sarcoma were found. Symptoms included intermittent crampy abdominal pain, intestinal obstruction, intestinal bleeding with anemia, and weight loss. The diagnosis was made on the basis of the clinical picture in addition to physical findings and pertinent x-ray contrast studies. The overall survival rate was 25%. The treatment of choice is surgical extirpation of the tumor whenever possible followed by appropriate adjunctive modalities.

A longitudinal survey of urban Polynesian infants in the first year of life provided data on gastro-intestinal bleeding and haemoglobin estimations. The results show that urban Polynesian infants are significantly more anaemic than their European counterparts, and that cow's milk-induced gastro-intestinal bleeding may be a significant cause of this anaemia.

A 42 year woman presented with malignant hypertension, anuria and hemolytic anemia with schistocytosis. The diagnosis of thrombotic microangiopathy was confirmed by early renal biopsy. Purely symptomatic treatment (peritoneal dialysis and hypotensive drugs) was supplemented by administration of heparin and Dipyridamole. Gastro-intestinal bleeding prevented early thrombolytic therapy. Microangiopathic anemia rapidly disappeared but anuria persisted. Three months later a second renal biopsy showed persistence of active lesions and absence of irreversible parenchymal damage. Streptokinase treatment was then instituted and followed by a rapid return of urinary output. Hemodialysis was stopped and renal function continued to improve over the following months. Two years later the patient remains well despite persistence of hypertension difficult to control. Creatinine clearance is stable at 20 ml/min. This observation suggests that late thrombolytic therapy may be effective in patients with thrombotic microangiopathy when histological findings do not indicate extensive irreversible lesions.

Angiodysplasia of the gastrointestinal tract is a disorder consisting of ectasia of submucosal and mucosal vessels, which causes acute and chronic bleeding. We describe the case of a 58-year-old man with a history of recurrent lower intestinal bleeding and severe anemia. Endoscopy and X-ray examination of the gastrointestinal tract failed to show the source of bleeding. Selective angiography of the superior and inferior mesenteric arteries revealed a vascular ectasia. The patient underwent ileo-cecal resection with remarkable improvement after surgery.

A 26-year-old male patient with pachydermoperiostosis is reported. He had severe anemia with myelofibrosis. Treatment with iron, prednisolone, oxymethorone and 1 alpha (OH)D3 were not satisfactory. But steroid pulse therapy with parenteral iron improved his anemia and pancytopenia, but was not sufficient to relieve the bone marrow fibrosis or splenomegaly. The mechanism of anemia which was considered to be multifactorial including gastro-intestinal bleeding associated with peptic ulcer or erosion and bone marrow failure due to myelofibrosis, is discussed.

Aortic stenosis is found in 15 to 25% of patients with gastrointestinal angiodysplasia. The usual treatment for haemorrhagic angiodysplasia associated with aortic stenosis is the same as for other types of gastrointestinal angiodysplasias: segmental intestinal resection, electrocoagulation and laser photocoagulation. The authors report the case of a 73 year old woman with a long history of gastro-intestinal bleeding and chronic anaemia requiring a number of hospital admissions for blood transfusions. The cause of this bleeding remained obscure for many years, as it was initially thought to be due to portal hypertension complicating cyrrhosis and a surgical porto-caval shunt was performed. Later, angiodysplasia of the colon was recognised and a segmental colonic resection was performed. These two surgical procedures had no effect on the chronic bleeding and finally the patient was referred for a gram negative endocarditis complicating aortic stenosis, previously considered to be non-surgical. After controlling the infection, the patient was sent for surgery of the aortic valve disease with mitral regurgitation in view of progressive degradation of left ventricular function. A double valve replacement with bioprostheses was undertaken with no complication. Finally, three years now after valve replacement, no further bleeding has occurred and control colonoscopy is normal. In the light of this case and a review of the literature of about 30 similar cases, the physiopathology and management of these patients is discussed with respect to the choice of valve prosthesis and the attitude to anticoagulant therapy. These observations suggest that in the presence of valvular heart disease at a surgical stage associated to an angiodysplasia, it is preferable to propose valve surgery to start with. Gastro-intestinal surgery is only indicated if haemorrhage persists after a period of observation.

Episodes of intestinal bleeding likely to endanger vital functions require detailed etiological and topographical examination before surgical intervention. Forty-two cases of serious haemorrhage of the lower digestive system in adults were studied retrospectively. The origin of the bleeding was localized preoperatively in 37 cases (88%). Four exploratory laparotomies were carried out after etiological examination including at least digestive arteriography. Hence it was always possible to localize the source of bleeding. We found it convenient to establish the order of the complementary pretherapeutic tests by taking into account two symptoms, acute active bleeding (AAB) and haemorrhage with acute anemia (HAA).

In order to determine the main clinical and laboratory manifestations associated with the infestation by an uncinaria during the first year of life, 42 children were studied from a group hospitalized between the years 1980 and 1985 in whom the main diagnosis at their time of leave from the hospital was parasitosis. Over 31 patients (74%) showed some degree of malnutrition, and severe in 24 of them (57% of the total). Clinical manifestations were mainly related to anemia (paleness, lack of air) and active intestinal bleeding (enterorrhagia, melena). Among the laboratory findings, 80% of the patients were shown to have anemia and in 24% of them, their hemoglobin levels were less than 5 g/dL, in more than half the anemia was normocytic normochromic. Also included are particularities concerning uncinariasis in the breast-feeding infant and some differences with the infection in the adult.
