Thoracic hemangiomatosis is an extremely rare condition of the thorax of unknown origin: thin-walled capillary blood vessels infiltrate the lung parenchyma, blood vessels, interlobular septa, bronchiolar walls and pleura. The infiltration of pulmonary veins and venules induces secondary pulmonary veno-occlusive disease and pulmonary hypertension with a slowly progressive clinical course. This condition can be associated with vascular dementia and disseminated intravascular coagulation (DIC).

[Current approaches in the treatment of gastrinoma metastases].

In the last years the therapeutic behaviour with regard to gastrinomas, has deeply changed becoming more and more aggressive. Nowadays, almost all authors recommend, after a serious treatment of the hypersecretion with omeprazole, an explorative laparatomy in all patients affected by gastrinoma even without a preoperative tumor localization. The multiple endocrine syndrome (MEN I) and the metastatic disease are excluded from the above practice. A careful examination of the most recent data available today in literature accompanied with our experience, even if limited, shows that only the surgical treatment allows a better survival also in metastatic disease. The surgical treatment is surely recommended in gastrinoma with pancreatic and duodenal lynphonodal metastasis. For hepatic metastasis all types of hepatic resection, the "wedge resection" included, can be suggested. After the first positive experiences, the hepatic transplantation can find a place among the therapeutic means against this kind of tumors.

[Study of the influence of the time of administration on the antihypertensive effect and nitrendipine tolerance in mild to moderate essential hypertensive patients. Value of ambulatory recording of blood pressure on 24 hours].

Forty-one patients with mild to moderate hypertension were included in a multicentre trial. The objective was to assess the influence of the time at which nitrendipine (Nidrel 20 mg) is taken on its efficacy and tolerance. The drug was administered once daily either in the morning or in the evening during 2 consecutive periods of 28 days. Efficacy was assessed on an ambulatory recording of blood pressure over 24 hours. Globally, nitrendipine results in a statistically significant drop in blood pressure which is not influenced by the time of administration. Treatment response varies greatly according to the initial value of ambulatory diastolic blood pressure. There is a clear antihypertensive effect if ADBP is greater than or equal to 90 mmHg and no hypotensive effect if ADBP is less than 90 mmHg. The incidence of adverse effects did not vary according to the time the drug was taken. Biological tolerance was excellent. Nitrendipine, administered once daily alone appears to be an efficient antihypertensive agent, well tolerated both clinically and biologically. Its efficacy is maintained over a 24-hour period regardless of the time at which the drug is taken.

[Manometric findings after sclerotherapy for esophageal varices].

To study the effect of sclerotherapy of varices on esophageal function, the motility of the tubular esophagus and L5S was recorded in 12 cirrhotic patients. The following results were obtained: abnormal wave patterns in the lower esophagus were frequently present after sclerotherapy; no impact on L5I pressure and function was found; the motility changes induced by the treatment have a tendency to decrease as time goes by except for the amplitude of the wave whose decrease persist long.
