[Current diagnosis of venous diseases of the lower limbs].

The haemodynamic of venous circulation of lower limbs seems to be not yet fully understood and different methods are available to study clinical patterns of venous insufficiency, deep venous incompetence or venous occlusion. Simple and common methods as venography, venous doppler and plethysmography are frequently used but other method as impedance plethysmography, ambulatory venous pressure, photoplethysmography, isotopes and thermography can be used for research or clinical investigation. The techniques and the indications of these tests are reviewed and critically analyzed to evaluate the best approach to the patients with venous pathology.

[Metabolism of somatotropin in severe liver diseases. Influence of the therapeutic administration of a liver extract].

Metabolic Clearance Rate (MCR) and half life of 125I Human Growth Hormone (HGH) have been studied in hepatopathic patients. A clear reduction of MCR and a prolongation of HGH half life have been found in all patients examined. After a 30 day therapy with crude liver extract (F.U. VIII ed.) both MCR and HGH half life have shown a tendency towards normalization. These findings are in agreement with the marked improvement of the clinical state of the patients and with the normalization of the laboratory indexes.

Poly-hormonal evaluationof pulsatile adenohypophysis incretory activity during sleep in normal, experimental and pathologic conditions.

Secretory patterns of some anterior pituitary hormones were recorded during sleep, and related to EEG-phases. The same observations were carried out in conditions in which the normal sleep course was intentionall (i.e., repeated arousals, administration of tryptophan) or pathologically (i.e. chronic schizophrenia) modified. Plasma gonadotropins (lh, fsh), growth hormone and ACTH were assayed. In basal conditions, the well-known peak of HGH, which corresponds to the delta phase of sleep, was confirmed. This peak is strictly linked to the number and duration of stage 4 sleep, and follows it in its experimental and/or pathological disturbances. The secretion of ACTH, on the other hand, seems to be completely independent from the morphology of sleep. The secretion of this hormone is typically phasic; along with this phasic secretion, a background secretion is detectable, which increases steadily during the sleep span, with maximal values in the early morning hours. Gonadotropin secretion is pulsatile, episodic and completely independent from the sleep phases, in basal as well as in experimental and pathologic conditions.

[Biliary ileus. Case report and therapeutic considerations].

The authors, after having described, a case of biliary ileus, analyse the principal pathogenetic aspects of the disease, and underline the diagnostic and therapeutic difficulties. They believe that the simple enterolithotomy represents, initially, the best therapy, in particular with patients in poor clinical conditions.

[Klippel-Trenaunay syndrome: clinical and surgical aspects].

The Klippel-Trenaunay syndrome is a rare syndrome of uncertain etiology. The characteristic elements are flat angiomatosis, hypertrophy of soft tissue and bone tissue and alterations of the venous system, with the exclusion of hemodynamically significant arteriovenous fistulae. The authors report a clinical case and review the international literature. Treatment is conservative in the majority of cases; surgery is reserved for patients with disabling morphological and functional alterations.
