[Incidence and onset of arterial hypertension and diabetic retinopathy in a population of subjects with diabetes mellitus]. / Considerazioni sulla incidenza e l'insorgenza dell'ipertensione arteriosa e retinopatia diabetica in una popolazione di soggetti affetti da diabete mellito.

The authors noticed a 50% increase in the incidence of arterial hypertension in diabetic subjects compared with non diabetic ones. Females are more affected in both types of diabetes mellitus and during the first ten years after onset of NIDDM. Diabetic retinopathy is more frequent in IDDM. In hypertensive diabetic females retinopathy is twice as frequent as in non-hypertensive female patients.

[Incidence and type of dyslipidemia in a diabetic population]. / Indagine sull'incidenza ed il tipo della dislipidemia in una popolazione diabetica.

The incidence of dyslipidemia in the diabetic patients tested was found to be twofold compared to the non diabetic population. The percentage was found to be higher in Fredrikson class IIb, unchanged in class IIa and diminished in class IVF.

[Autoimmune hypophysitis. Review of the literature and a case report]. / L'ipofisite autoimmune. Rassegna della letteratura e descrizione di un caso.

Lymphoid hypophysitis is a rare disease (fewer than 30 cases) which is associated with lymphocytic infiltration of the pituitary gland with complete or partial hypopituitarism, pituitary mass, and occurrence exclusively in women, often during pregnancy or in the postpartum period. The majority of the women had autoimmune endocrine and not endocrine disorders and in some cases antipituitary antibodies were present. For these reasons an autoimmune cause has been suggested. We report a patient in menopause with chronic thyroiditis and anti nuclear, anti smooth muscle and anti mitochondrial autoantibodies who developed a panhypopituitarism with an empty sella. This case is the third observation of a possible autoimmune atrophy of the pituitary.

[Influence of temperature and humidity on the reproductive efficiency of Ixodes ricinus (Linnaeus, 1758) and Hyalomma marginatum Koch, 1844 (Ixodoidea, Ixodidae)]. / Influenza della temperatura e dell'umidita' sull'efficienza riproduttiva di Ixodes ricinus (Linnaeus, 1758) e Hyalomma marginatum Koch, 1844 (Ixodoidea, Ixodidae).

Laboratory studies have been carried out on two species of ticks, I. ricinus and H. marginatum, showing different seasonal activity and different geographical distribution in nature. The purpose of the present study has been to investigate the effect of different combinations of temperature and humidity on the oviposition of I. ricinus and H. marginatum. An index of reproduction efficiency (no. eggs/wt female), established to relate the capacity of the females to produce eggs to their body weight, has been calculated; for I. ricinus 5 temperatures (18-20-25-27 and 30 degrees C) have been studied (Fig. 1), for H. marginatum 3 (25-30 and 32 degrees C) (Fig. 2) and for both species 2 R.H. (75-95%). An optimal range of temperature, within which the value of such an index doesn't change, has been demonstrated for both species by statistical testing (Table 1). A critical weight value as the minimum engorged female weight required for egg deposition has been identified with the weight of first female which has laid eggs. This weight, different in each species, is influenced by temperature and humidity.
