[A retrospective study of a patient population with benign thyroid pathology undergoing a partial thyroidectomy intervention]. / Studio retrospettivo di una popolazione di pazienti affetti da patologia tiroidea benigna sottoposti ad intervento di tiroidectomia parziale.

1,196 consecutive cases were analyzed. The results show that familiarity is a major risk factor on goitre insurgence; minor risk factor is pregnancy. The most frequent thyroid disease in pregnancy is the lymphocytic chronic thyroiditis; if the women have familiarity for thyroid disease the probability to display a thyroid disease in pregnancy is most augmented. Thyroid scintigraphy shows its elevated sensitivity: only in someone thyroid adenomas a difference occurs between scintigraphic imaging and surgical-anatomical presentation. Antimicrosomal antibodies relief presents highest utility in autoimmune thyropathies.

[Follow-up of a population of patients who underwent partial thyroidectomy for benign thyroid pathology]. / Follow-up di una popolazione di pazienti sottoposti a tiroidectomia parziale per patologia tiroidea benigna.

Natural history of partial thyroidectomy for thyroid disease has been studied in a population of 1196 consecutive cases surgically treated from 1977 to 1982. Follow-up analysis on this population (from six to eleven years) was carried out for appearance of recurrence. Generally, the recurrence incidence was small (only 9.9% of total population) but high frequency was observed for Graves' disease (46%) and lymphocytic chronic thyroiditis (21%). The substitutive/suppressive therapy administration did not influence recurrence of disease. Our results suggest that suppressive therapy does not modify the natural course of non cancerous thyroid pathology residual to partial thyroidectomy.

[Neurohypophyseal diabetes insipidus. Anatomo-clinical correlations]. / Diabete insipido neuroipofisario. Correlazioni anatomo-cliniche.

Eighteen patients aged between 14 and 60 years suffering from diabetes insipidus were studied. Diabetes insipidus was diagnosed by means of Robertson's test. All patients underwent C.T. scanning and evaluation of PRL basally and after TRH (200 mcg e.v.). Twelve patients (66%) showed neurological lesions (secondary central diabetes insipidus). Six of these patients had hyperprolactinaemia. Our data suggest that most of central diabetes insipidus are associated with central system nervous (S.N.C.) damage. In same cases the presence of hyperprolactinaemia suggests a brain damage. Therefore neuroradiological study is very important in all cases of neurohypophyseal diabetes insipidus.

[Morphogenesis of the lung bud from albino Swiss mice embryos, in organ culture in the presence of anti-lung serum]. / Morfogenesi dell'abbozzo di polmone ETAS in presenza, in coltura organotipica, di siero antipolmone.

The study of morphological figures and morphometrical data observed in lung buds from ETAS, cultured in Agar and OPEP medium, with or without SCAPEP, at different concentrations, in order to detect its influence on the morphogenesis, has shown that: OPEP (5:0) supports gradual morphogenesis for a limited time; OPEP + SCAPEP (5:2) supports gradual morphogenesis for a prolonged time; OPEP+SCAPEP (5:5) supports fast and deep morphogenesis for a short time; OPEP+SCAPEP (5:7,5) causes early inhibition of morphogenesis and survival; SCAPEP (5:0) stops instantly morphogenesis and survival.

[Morphometric method for the calculation of photographic areas]. / Metodo morfometrico per rilievi di aree fotografiche.

The investigation shows that, superimposing a transparent size unit known squared Reticle on a photographic image while printing, it's possible to calculate the area of image (directly) counting the reticle's squares taken up from image, or (indirectly) calculating the difference between the whole number of squares in the photographic field delimited by the major axes of image and one of squares free from image.

[Practical method for morphometric reliefs]. / Metodo pratico per rilievi morfometrici.

This morphometric method consists in: - to photograph, during culture's period, with constant magnification, the organ rudiment explanted in vitro; - to place on the single images, in printing, a transparent squared reticle with size unit known; - to compute the size values of the considered image counting the number of reticle's squares comprised in the image.
