Strong enhancement of extremely energetic proton production in central heavy ion collisions at intermediate energy.

The energetic proton emission has been investigated as a function of the reaction centrality for the system (58)Ni + (58)Ni at 30A MeV. Extremely energetic protons (E(NN)(p) > or = 130 MeV) were measured and their multiplicity is found to increase almost quadratically with the number of participant nucleons, thus indicating the onset of a mechanism beyond one- and two-body dynamics.

[Left atrial thrombosis in patients with antiphospholipid antibody syndrome and mesenchymal abnormal septum].

Antiphospholipid antibodies are a heterogeneous family of immunoglobulins that includes lupus anticoagulant and anticardiolipin antibodies. They are strongly associated with a clinical syndrome characterized by venous and arterial thrombosis and spontaneous fetal losses. This syndrome may be primary or else secondary to autoimmune or neoplastic diseases. The cardiovascular system is frequently involved with mitral or aortic insufficiency, juvenile myocardial infarction, and primitive pulmonary hypertension. However, the occurrence of intracardiac thrombi is rare. We describe a case of an intracardiac right atrial thrombus in a 19-year-old asymptomatic woman who was admitted in December 1998 to the Thrombosis Center owing to the finding, during routine work-up, of a prolonged activated partial thromboplastin time (71 s) and thrombocytopenia (71 x 1000/mm3), a positive antinuclear antibody test (1/320), positivity for lupus anticoagulant, and increased IgG (92 GPL-U/ml) and IgM (27 MPL-U/ml) anticardiolipin antibodies. Six months later, the patient presented with headache, edema and cyanosis of the face and jugular swelling. Transthoracic and transesophageal echocardiography revealed a right atrial mass which was clearly distinguishable from the tricuspid valve and extended to the superior vena cava. The patient was successfully submitted to surgical excision of the thrombus. Histology revealed that the mass was adherent to an abnormal septum consisting of mesenchymal tissue. Although the American Rheumatology Association criteria for the diagnosis of systemic lupus erythematosus were not fulfilled, the positivity of antinuclear antibody test is in favor of a lupus-like syndrome. The decision to opt for surgical excision of the thrombus was determined by the unclear nature of the atrial mass. It may be necessary that such patients be submitted to anticoagulant therapy for the rest of their lives or temporarily (6-12 months). This underscores the importance of the anatomical abnormality as a promoting factor. Transthoracic echocardiography (as well as transesophageal echocardiography in selected cases) must be considered as an essential component of the initial diagnostic work-up in patients presenting with antiphospholipid antibodies.

Fragment kinetic energies and modes of fragment formation

Kinetic energies of light fragments ( A</=10) from the decay of target spectators in 197Au+197Au collisions at 1000 MeV per nucleon have been measured with high-resolution telescopes at backward angles. Except for protons and apart from the observed evaporation components, the kinetic-energy spectra exhibit slope temperatures of about 17 MeV, independent of the particle species, but not corresponding to the thermal or chemical degrees of freedom at breakup. It is suggested that these slope temperatures may reflect the intrinsic Fermi motion and thus the bulk density of the spectator system at the instant of becoming unstable.

[Celiac disease (familial) associated with sarcoidosis. Clinical case and review of the literature].

The authors report a case of a 42 year-old patient, female, already suffering in 1990 from pulmonary sarcoidosis at 0 radiological stage, together with uveitis and relapsing erythema nodosum, with dyspepsia and weight loss which benefited from corticosteroidal therapy, repeatedly applied at the relapses of Erythema Nodosum. This therapy induced clinical recovery and marked weight gain. After 3 years (in 1993), the appearance of chronic diarrhoea, weight loss, oedemas of the lower limbs and altered laboratory findings which suggested malabsorbtive syndrome, made us verify with clinical-instrumental examinations (serum AGA IgA and IgG, Xilose test, perendoscopic jejunal biopsy) the diagnosis of fully clinically expressed adult coeliac disease. The screening of close relatives, showed that the patient's brother, HLA like (HLA A1-B8), was suffering from a less expressive coeliac disease. After a wide review of the literature, authors emphasize particular aspects of both diseases, reporting clinical manifestations, possible morbid linkage and prognostic factors. They underline epidemiological, pathogenetic and genetic/immunological similarity. bound to support a possible non-causal linkage of the diseases, even within the family. The authors think this linkage to be underestimated, because it is not often searched for on identified.
