Many of the aging Syrian hamsters maintained in our Division spontaneously develop atrial thrombosis accompanied by a consumption coagulopathy. The 50% mortality level is reached earlier by females (16 months) than by males (24 months). The incidence of thrombosis increases with age, beginning at 13.5 months in females and at 21.5 months in males, and the overall incidence (73%) is nearly the same for both sexes. Bilateral ventricular hypertrophy was found in thrombosed hearts. The hearts of most aged hamsters, whether thrombosed or not, had myxoid valvular thickenings and myocardial degeneration. Myodystrophic changes included hypertrophied nuclei, cytoplasmic vacuolation, fiber atrophy, and finally replacement fibrosis. Thrombosis probably resulted from local blood stasis secondary to cardiac failure. These hamsters may be an especially useful model for comparative study of the effects of aging and myocardial degeneration on spontaneous thrombosis.

Two thirds of the patients with peripheral arterial occlusive disease have to be treated conservatively, for only up to 30% can be revascularized by operative methods. Using the pharmacological differential treatment the grade of compensation and localization of the obliterative process has to be considered. Ignoring the usual basic therapy (elimination of heart failure and pathological bradycardia, systemic walking-exercise, anticoagulation etc.) intrafemoral long-term application of energetic phosphate (i.e. nucleotid-nucleosid-mixtures) leads to a positive result in nearly two thirds (n = 97 legs) with a degree of II to IV of Fontaine. Whereas the snakes' encyme Ancrod with the effect of defibrination was successful in almost 70% of the patients with arterial insufficiency (n = 45) including the degree II B (painless walking-distance under 100 meters). Energetic phosphates, applied to the arteria femoralis, are most successful in degree II with claudication intermittens. Ancrod should be used respectively for patients with pain during rest. These results are discussed with respect to compensation and localization of arterial occlusive disease, acute and chronic measurements of the hemodynamics by use of Doppler ultrasound and strain gauge plethysmography and with respect to variation of the concentration of the metabolic parameters lactate and pyruvate--the latter when defibrination was performed.

In eight dogs, acidosis was induced by the infusion of lactic acid into the superior mesenteric artery in a dose of 5.0 to 12.5 millimoles per kilogram during a 30 minute period. Four dogs out of five in which the lowest pH of arterial blood was lower than 7 developed a typical acute disseminated intravascular coagulation, accompanied by a sudden elevation of arterial and portal venous pressure. In these four dogs, refractory shock developed between 0.5 and five hours after lactic acid infusion. The other four without disseminated intravascular coagulation maintained a normal blood pressure and survived until sacrifice six hours after infusion. In two dogs, systemic infusion of 10 millimoles per kilogram was performed in the same interval as the former. Both died from cardiac failure without occurrence of disseminated intravascular coagulation before the infusion was completed. The dogs with disseminated intravascular coagulation revealed a marked deterioration of coagulative system and generalized thrombi in the intestine, liver, lung and kidney. Minimal changes in these parameters were observed in the dogs without disseminated intravascular coagulation. The results suggest that the infusion of lactic acid into the superior mesenteric artery is a convenient model for the production of disseminated intravascular coagulation and resultant shock.

A 14-year-old girl with acute promyelocytic leukemia (APL) developed cardiomyopathy following chemotherapy for remission induction and subsequent consolidation consisting of cumulative doses of 644 mg/m2 of daunorubicin and 31 mg/m2 of mitoxantrone. Six months after the first complete remission, when relapse of APL was recognized an allogeneic bone marrow transplantation (BMT) from her HLA-identical brother was performed. A preconditioning regimen, consisting of cytarabine (Ara-C, 2 g/m2/day x 3 days and 4 g/m2/day x 3 days), total body irradiation (TBI, 1200 cGy) and etoposide (VP-16, 50 mg/kg) caused moderate gastrointestinal symptoms and transient hemorrhagic cystitis, but did not worsen her cardiac function. Both continuous intravenous administration of heparin to control DIC and continuous low dose dopamine infusion to prevent cardiac failure achieved their purpose. The patient is leukemia-free and has no symptoms related to cardiomyopathy at the eight month after BMT. A preconditioning regimen (Ara-C, TBI and VP-16) appeared to be suitable for BMT to a patient with anthracycline-induced cardiomyopathy.

This report describes four infants with hepatic hemangioendotheliomas and cardiac failure who had extensive portal venous and systemic collateral arterial supply complicating hepatic arterial embolization. One patient with diffuse hepatic hemangioendothelioma and extensive portal vein supply but minimal systemic collateral arteries showed no improvement after technically successful hepatic artery embolization and died with disseminated intravascular coagulation and sepsis. A second infant with extensive portal vein and collateral supply died without undergoing embolization. Two patients had portal vein-hepatic vein fistulas as well as an extensive systemic arterial supply. Both infants tolerated staged hepatic and collateral artery embolization, although one patient died of congestive heart failure, probably related to pulmonary hemangiomas. The authors conclude that angiographic study of the potential collateral vessels and portal venous circulation should be performed before embolization. Patients with shunting from the portal vein to the hepatic vein and minimal systemic arterial collateral circulation should not undergo hepatic artery embolization.

A 54-year-old man received insertion of an acupuncture needle into the region extending from the posterior neck to the back on two occasions for the treatment of shoulder stiffness. Two weeks after the second acupuncture, he developed fever, dysarthria and mictionary disturbance, finally reaching the condition of tetraplegia. He was immediately admitted to an emergency room in our hospital, and was diagnosed as sepsis with DIC, ARDS, heart failure, renal failure, liver failure, and myelitis. After one month, he recovered with transverse myelopathy as a residual deficit. Neurological findings showed transverse myelopathy below the level of Th2 at that time. Cervical CT revealed an irregular low density at the periphery of the cervical vertebra from the C2 to C4 level. Cervical MRI revealed an irregular swelling of his spinal cord from the C2 to C7 level. We explained the mechanism of transverse myelopathy in this case as follows. After the acupuncture, he suffered a focal infection of the region of needle insertion, and then the infection expanded to the cervical vertebra, thus causing osteomyelitis, sepsis, and finally cervical myelitis. Direct injury of the spinal cord and nerve roots as a complication of acupuncture was previously reported, but indirect injury of the spinal cord due to myelitis had not been reported except our present case. Careful attentions should be paid to the complications of acupuncture.

We report a neonate who presented within hours of birth with severe congenital cardiac failure, thrombocytopenia, and consumption coagulopathy, caused by a massive hemangioma of the left arm. Initial treatment with glucocorticoids, platelet and clotting factor replacements, and cardiovascular support failed to control these hemangioma effects and amputation was avoided only when axillary artery ligation and an intermittent pneumatic compression device, manufactured in this hospital, achieved control of this lesion and hastened its subsequent resolution. The treatment of such lesions is reviewed, emphasizing individualized treatment protocols, and stressing that such lesions and their effects, cannot be regarded as variants of a single disease entity when planning management.

ARDS occurs in patients with no underlying pulmonary diseases, induced by stresses, such as lung injury, acute pancreatitis or infections. It is an acute respiratory disorder which manifests as acute dyspnea, hypoxemia and lowered pulmonary compliance. Greene et al, used balloon pulmonary angiogram (BOPA) as diagnostic tool to morphologically observe the pulmonary disorder. To study the dynamic pulmonary circulation and morphology of the peripheral pulmonary artery of ARDS, we performed this method for acute cardiac failure and ARDS patients. Pulmonary hemodynamic changes in ARDS revealed mild pulmonary hypertension and increased PVR, while C.I. and PCWP remained within a normal range. The findings of BOPA in ARDS showed that the frequency of PAFD correlated with the the presence of an elevated PVR and DIC, and pulmonary vasoconstriction was detected by measurement of PA diameter (B/A2).

We describe a 7-years boy by with a meningococcal sepsis due to Neisseria Meningitidis, with very serious evolution of cutaneous necrosis, initial D.I.C. and heart failure. The clinical picture do not improve with antibiotic therapy (CAF-penicillin), but the association ceftriaxone + tobramycin results in rapid improvement. The cutaneous necrosis, especially evident on gluteus, arms and legs, were treated locally with AgNO3 and penicillin-solution. After 4 weeks of treatment, also this cutaneous involvement improved and now the boy is healthy, without residual signs neither systemic nor cutaneous.

Fetal acardia is a rare abnormality of multiple pregnancies, which is lethal for the affected fetus and can cause death in 50% of normal co-twins. Antenatal recognition with early ultrasound is essential to institute a prospective management to improve the outcome. Our communication outline the difficulties which may be encountered in ultrasound diagnosis. In particular the problem of distinguishing a fetal heart from large pulsating mediastinal vessels, which can be present in these fetuses, and the difficulty of diagnosing death in an acardiac fetus. Our report confirms that the co-twin remains at increased risk of sudden death, even without ultrasound evidence of cardiac failure or biochemical compromise. The finding in this fetus of intravascular fibrin deposits suggests the possibility of acute disseminated intravascular coagulation, not previously reported in association with an acardiac twin.
