Skin involvement in hemopathies: specific cutaneous manifestations of acute nonlymphoid leukemias and non-Hodgkin lymphomas.

The course of a hemopathy may be characterized by the appearance of cutaneous lesions. In such cases a correct histological investigation is needed, especially when the lesions have an aspecific appearance. It is important, therefore, to recognize the cases characterized by cutaneous involvement of typical systemic disease cells. Lymphomas and leukemias are the hemopathies which more frequently present specific and nonspecific cutaneous manifestations (with an approximate incidence of 3-40 and 6-50%, respectively). In the period 1977-1983 we examined 337 patients affected with acute nonlymphoblastic leukemia and 243 patients affected with non-Hodgkin lymphoma, in order to verify the incidence of specific cutaneous manifestations.

Flunarizine, cerebral blood flow and reversion of experimental atherosclerosis in rabbit.

Flunarizine is a calcium entry blocker active in the treatment of peripheral vascular disease. The present study was performed to evaluate the effect of flunarizine on cerebral blood flow (CBF) and lipidic patterns in rabbits with dietary experimental atherosclerosis. Since it is well known that there is only a slight correlation between the severity of atheromatous lesions ascertained at necroscopy and the severity of clinical symptoms of cerebral vascular disease, the effect of the drug was assessed by measuring the CBF and compartmental distribution of blood flow in unanaesthetized rabbits by the intracarotid Xe-133 clearance method; blood pressure, plasma lipids and tissue fat infiltration were also checked. An atherogenic diet brings about significant impairment of CBF. Flunarizine is inactive in normal rabbits if chronically administered at the daily dose of 10 mg/kg p.o. In atherosclerotic rabbits chronic treatment with flunarizine induced a pronounced increase in cerebral haemodynamic parameters. Arterial pressure and blood pCO2 were not significantly modified. Lipidic patterns were not markedly improved by flunarizine treatment in comparison with values for atherosclerotic animals. These data demonstrate that flunarizine treatment counteracts the haemodynamic effects of cerebral atherosclerosis. The pronounced activity on the cerebral vessels is accompanied by a weak antilipaemic effect.

Effects of human calcitonin on pain in the treatment of Tietze's syndrome.

Tietze's syndrome consists of pain, tenderness, and swelling of the costosternal or sternoclavicular joints. The etiology is unknown, although microtrauma or rare infections have been though to be responsible for the lesion. Conventional therapy consists of anti-inflammatory drugs, sometimes combined with chemotherapeutic agents and antibiotics. Surgery is usually deemed necessary for cases that do not respond to conventional therapy. Experience with the use of human calcitonin in five patients suffering from severe Tietze's syndrome who did not respond to conventional therapy is reported. Symptoms improved within seven days, and all symptoms and signs had disappeared after one month of treatment. The beneficial effects of calcitonin are believed to result from the hormone's well-known analgesic and immunomodulating effects.

Neurilemmoma of the ciliary body: report of a case.

A case of ciliary body neurilemmoma is described. This neoplasm is extremely rare in the uveal tract and has been reported only once in the ciliary body. After extensive clinical studies of the rapidly growing tumour enucleation was performed. Subsequent histological examination showed typical features of highly vascular benign neurilemmoma. The main clinical and pathological features are reported and diagnostic problems are discussed.

[Chronic brucellosis: diagnostic problems and case presentations].

Chronic Brucellosis is an infection disease, which is still of great clinical interest whether due to the difficulties of diagnosis involved or to the peculiar course of the illness. For this reasons, we have considered several cases of Chronic Brucellosis observed over a period of 10 years, which have presented particular problems of diagnosis. Furthermore, we have underlined the importance in the diagnosis, of intradermal reaction and the hemoreaction to the anamelitina injection. We propose therefore, to consider their diagnostic specificity by analyzing the results obtained.

Abnormal splenic uptake of red cells in long-lasting iron deficiency anemia due to self-induced bleeding (factitious anemia).

The authors report on six cases of chronic iron deficiency anemia in which a diagnosis of factitious anemia was made. Erythrokinetic studies demonstrated iron deficiency and blood loss. Besides these features, two kinetic abnormalities are described: precocious splenic sequestration of red cells and excess hemolysis. This hemolytic syndrome seems to be correlated to the duration of anemia rather than to its severity.
