Histoplasmosis capsulati in Italy: autochthonous or imported?

Reports of a few apparently autochthonous cases of human histoplasmosis and results of epidemiological research suggested the autochthonous presence of the disease in Italy. Identifying two new histologically documented cases of Italian patients, who had never been abroad, and, the positive results of a histoplasmin reactivity survey carried out in the Province of Cremona, Italy confirmed this possibility.

[Validity of the AgNOR count in cervical pathology].

Nucleolar organizer regions (NORs) were counted on ten cases each of normal ectocervix, CIN 1, 2 and 3 to verify the possibility of a differentiation between the various grades of CIN and between them and condylomata. Counts were performed on the full thickness of the tissue, layer by layer (stratified counts). A significant difference (p < 0.05) was found between the means of normal tissue toward condylomata and CIN 2 and 3 and between CIN 1 and CIN 2 and 3. There was no significance (p < 0.05) between normal tissue and CIN 1, between CIN 2 and 3 and between condylomata and CIN 2 and 3. The range of variations on the counts was associated with overlapping between the various cases. Our data showed also a progressive rise in mean NOR values from normal tissue to CIN 3. The stratified counts showed in all the groups a rise from basal to parabasal cells. Counts on parabasal and intermediate layers distinguished two groups of cases. In one there was either the same number of dots or a further rise from one layer to the next, while in the other a definite decrease was seen. The former pattern may be related to a potential for malignant evolution of the lesion. NORs should be counted in all cases of CIN and condylomata to treat more aggressively those lesions which present the pattern of a progressive rise of NORs from basal to intermediate cells.

[Bone marrow cryptococcosis as the first manifestation of AIDS].

Bone marrow cryptococcosis as initial sign of AIDS. The Authors describe a case of bone marrow cryptococcosis in a patient, female aged 27, in which a toluene-induced aplastic anemia was suspected. The mycosis was at first extracerebral and represented the initial manifestation of unexpected AIDS. The Authors discute the symptomatology and the clinical findings leading to the diagnosis and remark the main point of bone marrow evaluation as aid in diagnosing the infective pathology.
