[Conservative treatment of chyle fistula of the neck following a reintervention of cervical bilateral lymphectomy for medullary carcinoma of the thyroid. Case report].

Chyle fistula is an uncommon serious complication of neck surgery, occurring in 1-3% of radical neck dissections. An untreated chyle leak is a potentially dangerous condition that may rarely lead to hypovolemia, hyponatremia, hypochloremia, hypoproteinemia and lymphopenia. Anatomic variants of the terminal portion of the thoracic duct and suction drainage in the neck wound play a primary role in causing this kind of lesion.

[Diagnosis, surgical treatment and follow-up of the hyalizing trabecular adenoma of the thyroid].

In the last twenty years, we submitted 853 patients to thyroid surgery. We found only in ten patients a hyalinizing trabecular adenoma at the (histological control), as a confirmation of the rarity of this tumour. The authors report a retrospective analysis of this cases to document the clinical features and the evolution through a long-term follow-up that has showed no recurrent disease.

[Correlations between splenectomy and allergic symptoms. Preliminary results of a study concerning IL-4 and IgE serum level].

The Authors, studying the condition of immunodepression observed in patients who underwent splenectomy for traumatic lesion, noticed that a significant part of them complained of allergic symptoms. These seemed to appear only in subjects whose Th2 lymphocytes functionality was preserved--as witnessed by normal or increased IL-4 serum level--showing an increased level of IgE too, thus confirming the role of Th2 lymphocytes in stimulating IgE synthesis. On the contrary splenectomized patients with functional harm of the Th2 lymphocytes--proved by low IL-4 serum level--did not show increase of haematic IgE level nor allergic manifestations.

[Chronic abdominal pain and peritoneal mesothelioma: case report].

Chronic abdominal pain syndrome is becoming increasingly important. The main symptom is persistent abdominal pain, which may vary intensely and be associated with constipation and episodes of vomiting, evolving towards sub- or total occlusion of the bowel. A 65-year old man presented with malignant peritoneal mesothelioma, with environmental asbestos exposure and chronic abdominal pain for more than one year.
