[Allergy to insect venoms. Study of a population of apiculturists]. / Allergia al veleno di insetti. Studio di una popolazione di apicultori.

The results of a study conducted on a group of local beekeepers are presented. Total IgE and specific IgE for bee and wasp venom were assayed and these data correlated with anamnestic details obtained by means of a questionnaire.

[A case of lymph node aspergillosis]. / Su di un caso di aspergillosi linfonodale.

Lymph node aspergillosis in an otherwise healthy patient receiving neither antibiotic corticosteroid or immunodepressive drug treatment is an uncommon event. In addition the case reported revealed no deficiency in humoral or cellular immunity. The possibility that aspergillosis may occur in cases without identifiable immunodeficiency is therefore put forward.

[Alpha2-macroglobulin in diabetic disease and in its microangiopathic complications]. / L'alfa2-macroglobulina nella malattia diabetica e nelle sue complicanze microangiopatiche.

The role of alfa2-macroglobulin in diabetic microangiopathy pathogenesis is described. A study of the behaviour of this protein in a group of diabetic patients with and without microangiopathy and in a control group of healthy patients has been carried out. It has been found that the protein greatly increases in diabetic patients with microangiopathy. On the basis of these results, it is suggested that dosage of alfa2-macroglobulin can be a possible test for evaluating microangiopathic complications in diabetes.

[Splenic extramedullary hematopoiesis in myelofibrosis. Pathogenetic considerations apropos of a personally studied case]. / L'ematopoiesi extramidollare splenica in corso di mielofibrosi. Considerazioni patogenetiche a proposito di un caso di osservazione personale.

A case of myelofibrosis developing in a peripheral leukaemia-type situation after splenectomy is presented. An examination of the hypotheses on the pathogenesis of myeloid metaplasia during myelofibrosis lead to the proposition that it may be caused by the "seeding" of medullary precursors in the spleen.

[Acute plasma-cell leukemia. Report of a case]. / La leucemia plasmacellulare acuta. Comunicazione di un caso

A case of fatal, diffused plasmacytoma is presented. The picture also included leukaemia and is felt to be an example of plasma-cell leukaemia, as opposed to plasmacytoma in the light of the anatomical and clinical features of the onset and course: high and very pronounced plasma-cell leukocytosis, diffuse proliferation of the plasma cell series in the bone marrow, spleen and lymph nodes, infiltration of plasma cells in the parenchymal organs, extremely rapid progress with serious anaemia, haemorrhage, general organic involvement, high fever, and infection.
