Contributions toward the study of changes in the microvascular-tissual system in diabetes mellitus (Observations on 50 biopsies of the finger-tip).

Fifty biopsies of finger-tips, from diabetic patients were examined. We wish to emphasize, of damage in the blocking devices and in the preglomic arterioles as opposed to the limited modifications produced in the small dermic and hypodermic arteries. The glomera are almost constantly affected in their various components: in particular, the fusion of the glomic capsule with the intra- and extraglomic connective should be noted, as well as the presence of accumulated P.A.S. positive material among the mioepithelioid cells in the intermediate segment. The capillaries are frequently affected by hyperplasia of the intimal endothelium, sometimes with subocclusive phenomena, while the basal membrane is thickened and P.A.S. positive more often in extraglomic than in intraglomic capillaries.

Correlations between capillary microscopy and electrocardiographic results in the diabetic.

Ninety-nine diabetics were simultaneously given a capillaroscopic examination of periungual walls and an electrocardiogram evaluated according to the Minnesota Code. From these tests the following data were recorded: a. the number of knobs revealed by capillaroscopy is inferior, in a statistically significant manner, in groups having "major abnormalities"; b. capillaroscopic abnormalities did not seem to be definitely correlated to age, but rather to the length of time diabetes mellitus was present; in particular, these abnormalities were quite evident in subjects diagnosed as diabetics for the first time. This procedure is therefore extremely useful for the early diagnosis of diabetic microangiopathy; c. electrocardiographic abnormalities are correlated to patient's age, whereas are not related to the period of the illness. Although the small sampling obliges us to maintain certain reservations, such abnormalities were more frequent in subjects taking antidiabetic drugs orally.

[Case of crural ulcer during polycythemia vera].

A case of polycythaemia vera, in which a crural ulcer appeared numerous years after the onset of the disease, is reported. The absence of important angioneurological lesions and the signs at cutaneous lesion level of capillary dilatation, suggest that crural ulcer is a complication of polycythaemia. Aetiopathogenetic aspects are also discussed.

Kindler syndrome: report of a case with ultrastructural study and review of the literature.

Kindler syndrome is characterized by a generalized, progressive poikiloderma with cutaneous atrophy, congenital acral skin blistering, and photosensitivity. Since the first description, approximately 70 cases have been reported worldwide, but ultrastructural studies were performed in only five patients. In none of these patients were biopsies done at birth. In our patient ultrastructural studies were performed both of the blister at birth and of the poikilodermatous and atrophic skin at 6 years of age. Some ultrastructural features in the context of a bullous disease of the newborn that resembles epidermolysis bullosa, should alert investigators to the possibility of Kindler syndrome even in absence of the typical clinical signs.

[Dunbar syndrome: apropos of a case (review of the literature)].

The authors report a case of the uncommon and still discussed "coeliac artery compression syndrome". On the basis of the literature's review and of their own observation they conclude that Dunbar's Syndrome is a real clinical entity. The section of the arcuate ligament and the subadventitial removal of the pericoeliac tissue, or, whenever indicated, an aorto-coeliac by-pass, seems to be the "gold standard" in the surgical treatment.

Lyme arthritis presenting as adult onset Still's disease.

Lyme disease and adult onset Still's disease share several clinical characteristics such as fever, lymphosplenomegaly, skin involvement, and arthritis. Borrelia burgdorferi has been recognized as the cause of Lyme disease and an infectious agent has been suspected, at least as triggering factor, in adult onset Still's disease. This work is concerned with a patient affected by atypical Lyme disease originally diagnosed as adult onset Still's disease. B. burgdorferi infection must be suspected in cases of arthritis suggestive of adult onset Still's disease.
