[Double cardiac fibroma in a newborn infant].

The authors describe the autopsy finding of two fibromas within the left ventricular wall of a five-day-old newborn. Histochemistry and immunohistochemistry showed the lesion as a purely fibroblastic proliferation, with intense elastic fibers formation and secondary morphological alteration and biological damage of the pre-existing muscular fibers. The authors, on the basis of the phases of the cardiac metamers development and of myocardial tissue differentiation, exclude any relationship with disembryogenetic factors, and hence the hamartomatous origin of the lesion, despite their onset in the first months of intrauterine growth.

[Ventricular hypoplasia in congenital heart diseases].

Twenty-seven cases of autopsy showing hypoplasia of one of the ventricular cavities, prevalently the left, were selected from a series of 103 congenital cardiopathies (1979-1990). In 9 cases ventricular hypoplasia formed part of complex malformative syndromes with a well-known physiognomy: a further 18 cases showed a complete (9 cases) or incomplete (9 cases) hypoplastic heart syndrome. Subjects were prevalently female and the presence of other malformations indicating a genetic dysfunction was less evident than in other cardiopathies. The different pathogenetic hypotheses are discussed in the light of macro- and microscopic morphological factors, of which the most plausible is that involving an anomalous position or orientation of the musculo-membranous folds which give rise to the septation system of the various metamers of the cardiac tube.

[Evaluation at midterm of the clinico-instrumental efficacy and tolerance of picotamide in patients with obliterative arteriopathy of the lower limbs].

After a 4-week wash-out period, picotamide was administered to 25 patients affected by chronic arteriopathy of the lower limbs (scale 2 according to Fontaine) at a dose of 900 mg/die for 90 days, and then at a dose of 600 mg/die for a further 90 days, in order to assess its efficacy according to the following parameters: duration of gait, residual pressure index (RPI) resting the ankles, hematochemicals, electrocardiogram. At the end of the study a statistically significant increase was observed in the duration of gait and RPI at the ankles and, of the hematochemical parameters, in an increase in fibrogenic degradation products. Adverse reactions were only observed in 3 patients and regressed spontaneously. In conclusion, picotamide was found to be efficacious in patients affected by chronic obliterating arteriopathy of the lower limbs with the possibility of reducing the dose after 3 months of therapy.

Normalization of bronchial exocrine pathology after endobronchial treatment with ambroxol.

A clinical study was performed on nine adult in-patients suffering from chronic intercrisis bronchopneumopathy, to evaluate whether a local endobronchial treatment with ambroxol could be effective in stabilizing the secretory activity of bronchial glands modified by phlogistic injury. The patients underwent bronchoscopic examination and deep biopsy, before and after treatment with local medication of ambroxol every other day for 30 days. In addition to morphometric measurements, detailed histochemical examinations were performed on the secretion of mucous acinic and glandular excretory ducts. The trial proved that the treatment with ambroxol stimulates serous acini, restoring normal production of sulphomucins and also of mucous acini, increasing the metabolic activities of acid glycoproteins and proportionally curtailing the excessive synthesis of glycoproteins. Ambroxol can therefore be considered a mucoregulating drug.

Survival rate after resection for bronchial carcinoma.

Among factors influencing long-term survival of patients how had undergone resection for carcinoma of the lung, the most important seems to be the extent of the cancer at the time of resection, determined by histopathological studies of the resected specimen.
