The mole can transform itself in melanoma. The transformation is caused in some's opinion by congenital cells, in some's opinion by external elements (metabolic, physical, caustic, etc.). The authors lean to external causes metabolic, physical caustic) and they consider useful the chirurgical and radiant treatment.

Massive, active bleeding of the oesophageal varices in cirrhotics requires immediate, comprehensive and continuing appraisal of determining risk parameters (liver function and morphology, hyperdynamic syndrome, renal function, dynamic angiography of the splanchnic circulation). When survival is linked with stopping the haemorrhage, indications must not be looked at restrictively and operation has to be fast. Minor surgical measures aimed at temporary control of the haemorrhage are not satisfactory. Side-to-side portacaval anastomosis is effective in terms of reducing portal pressure and controlling the haemorrhage. Mesenterico-caval shunt with H-dacron graft interposition is sufficient dynamically and has less effect on porto-hepatic flow. Long-term results with this technique requires further study.

Now therapeutic different possibilities of goitre pathology seem well defined, in front of limit of suppressive therapeutic range in initial stages, prevalently diffuse, that interest young people and arise in jodic want lands; it's possible that medic theraphy ends can't be obtained because of not responders patient, or even for possibilities of controindications. Local presence of suspicious nodules and the need of goitre volumetric reduction for aesthetical and compressory ends, with the possibility in course of time of functional changes are sure reasons to surgery. Certainly main problems exist about surgery definition of multinodular disease with bilobar involvement where there is comparing between total and subtotal thyroid exeresis. Now by literature analysis and our School experience we think that surgery choice, considered before operation, must find absolute assurance after preoperative morphotopographic careful exploration of thyroid. We think that total thyroidectomy must be done when it's certain a total gland involvement, reserving subtotal thyroidectomy in the other cases; always employing a careful surgery technique, keeping operative field interely bloodless to identify important structures and dissection plan narrowly close by capsule.
