[Surgical management of hereditary medullary carcinoma of the thyroid in patients with "RET" proto-oncogene mutation].

The authors report their results in 64 individuals belonging to 11 families with MEN 2 and familial medullary carcinoma of thyroid (CMT) syndromes. They show amplification and restriction techniques, type, site and incidence of genetic alteration in the observed cases; besides they illustrate the adopted surgical management related to the mutation. They stress the concept that genetic test allows to detect the population with altered gene before laboratory or clinical evidence, with the great advantage to indicate an early surgical approach. If it is shown a multi-organ disease, as in one patient with CMT associated with bilateral pheocromocytoma, the two diseases must be treated during the same operative time.

[Medullary carcinoma of thyroid gland].

The authors present the characteristic features of medullary carcinoma of thyroid (CMT) and underline the necessity to identify RET proto-oncogene that is the cause of hereditary transmission of CMT. Physiology of C cells and clinical syndromes are reported and the importance of a genetic screening in population at risk is emphasized; this test has shown to be reliable and easy to apply. They report their experience on techniques of amplification and restriction for RET proto-oncogene identification in relatives of patients with MEN or familial CMT syndromes. This study has allowed to recognize a population bearing the oncogene responsible of the disease and to achieve a correct prophylactic therapeutic management.

Carcinoma, Medullary↗

[Nuclear risk and thyroid neoplasms in infancy].

Thyroid carcinoma is a disease with low incidence in adult and rare in child. The authors give oncogenic risk factors of the disease and underline environment factors as iodine deficiency and radiation pollution that, as shown in certain world areas, has a strong effect in the epidemiology of this disease. Eventually radiation's are the most important oncogenic risk factors but and adequate iodine prophylactic program can be considered a valid shield to prevent this disease.

[Primary adenocarcinoma of the duodenum].

Adenocarcinoma of the duodenum represents a rare neoplasia characterized by an indefinite symptomatology, at least early, and deceitful, that, therefore, arrives at surgeon, almost always, in advanced stage. The Authors, taking from a clinical case, recently observed, as a starting point, review the literature, referring the etiopathogenetic hypothesis that explain the relative rarity of this neoplasia. They therefore report the diagnostic and therapeutic procedure to carry out in these patients.

[Gastric precancerous conditions].

The Authors examine the anatomopathological and clinical features of the main gastric precancerouses and explain the diagnostic therapeutic protocols used. The diagnostic and therapeutic strategy can not leave a strict interdisciplinary collaboration out of consideration between radiologist, endoscopist, anatomist, gastroenterologist and surgeon. They conclude, in fact, affirming that the mentioned collaboration represents the one possibility for improving the results at distance of this neoplasia.

Abdominal attack of hereditary angioedema associated with marked leucocytosis. A case report.

Hereditary angioedema (HAE) attacks are not usually associated with an increase of peripheral blood leucocytes. In a 25-year-old woman suffering from HAE a marked leucocytosis (31,000/mm3) with polynucleosis was observed during a severe attack of the disease. Awareness of the underlying disease, physical examination and the results of instrumental investigations allowed for appropriate treatment avoiding invasive procedures. A leucocytosis of the severity observed in our patient suggests that the abdominal attack of HAE can involve the peritoneum as well as the intestinal mucosa. Thus, in a patient with an attack of abdominal pain the presence of leucocytosis does not exclude the diagnosis of HAE.

Abdominal Pain↗

[Biliary peritonitis caused hy hydatid disease].

After specifying that rupture of a hydatid cyst in the peritoneal cavity is one of the most serious and rarest complications of hepatic hydatidosis, attention is paid to the peritoneal hydatid (o chole-hydatid). The aetiopathogenetic mechanisms and the anatomo-pathological features of this type of lesion are described in brief. Finally, the personally employed diagnostic protocol and therapeutic strategy in the face of this feared complication are reported.

Chylous Ascites↗

[Clinical remarks on acute volvulus of the cecum].

On the basis of a case of acute volvulus of the caecum, the rarity of the condition is stressed and its aetiopathogenetic and clinical aspects analysed, particular emphasis being laid on therapy.

Acute Disease↗

[Conservative surgical treatment of acute hemorrhagic necrotizing pancreatitis].

The Authors though in theirs' opinion medical treatment is the primary therapeutical approach to Acute Necrotizing Haemorrhagic Pancreatitis (A.N.H.P.), state that the surgical treatment is indicated as soon as the necrotizing haemorrhagic evolution of the disease is strongly suspected. It should be conservative in type acting on the evolution of the disease and saving the anatomic integrity of the pancreas. The surgical technique adopted is described which consists in removing cellular debris as well as highly toxic necrotic pancreatic apparatus and it is completed by the endo-retroperitoneal perfusion for a continuous washing of the peritoneal cavity. In conclusion, they report their personal experience with 16 patients affected with A.N.H.P.

[Use of tumor markers in monitoring thyroid carcinoma].

The authors report on their experience regarding the use of tumours markers for the pre-operative monitoring and subsequent follow-up of patients suffering from thyroid carcinoma. All patients were subjected to radio-immuno-assay for circulating thyroglobulin, a valuable indicator of residual and metastatic thyroid tissue. The patients suffering from medullary carcinoma of the thyroid and their immediate families were also monitored by periodic thyrocalcitonin assay. A further tumour marker assayed was CEA, levels of which are raised in the presence of thyroid neoplasms at an advanced or metastasizing stage. The authors conclude by presenting the results obtained and confirm the usefulness of these tumour markers in the study and follow-up of patients with thyroid carcinoma.

[Aminoglutethimide in the treatment of metastasizing breast carcinoma in old age].

After first analyzing the basic pathophysiological aspects and the mechanism of action of aminoglutethimide, the authors report on their experience with the use of this steroid biosynthesis inhibitor in a group of geriatric patients with advanced cancer of the breast. After illustrating the results of their study, the authors conclude by stressing that the use of this drug appears to improve the quality of life of the patients with a significant increase in rates of complete or partial remission of the neoplastic disease.

[Importance and limitations of the immunological monitoring of patients with malignant tumors].

The authors, after considering the incidence of neoplastic diseases is particularly high in subjects suffering from congenital or acquired immunologic lacks, assert the importance to perform an immunologic monitoring in the patients bearing malignant neoplasms, with the purpose to identify and calculate the direrent deficits of the sheltering organism. Then, they state the method adopted for the study of the cellulo-mediate immunity (in vivo and in vitro) and the humoral one. At last, on the basis of the results they obtained, the Authors, as a conclusion, affirm there is always in neoplastic patients a certain degree of depression of tumour immunity (especially if cellulo-mediate), and it can be put in relation to the evolutive stage of neoplasm.

[Colo-rectal precancerous conditions: anatomo-pathologic and clinical aspects].

The authors, after emphasizing the value presently ascribed to the conception of "epithelial displasia" as initial histologic and cytologic alteration, common to all groups of patients with high risk of development of colorectal cancer, review the mani precancer lesions of large intestine. As a conclusion, they affirm the main target one presently aims at for the screening in groups with high risk is to precociously identify the stage of transformation of epithelial displasia into carcinoma, so as to be able to set up a timely treatment.
