We report a 64 year-old male, living in a rural area, with a history of a thyroid nodule subjected to a fine needle aspiration 18 years ago. He consulted this time for a goiter associated to dyspnoea and dysphagia. A chest X-ray and a neck CAT scan showed a calcified nodule in the superior mediastinum of thyroidal origin, that displaced airways and blood vessels and a small thyroid nodule of uncertain origin. ⋯ The patient was operated, performing a subtotal thyroidectomy A calcified nodule measuring 8 x 6 x 6 cm and another nodule measuring 10 mm were found during the surgical exploration. The pathological examination of the surgical piece disclosed a calcified hydatic cyst and a focal nodular hyperplasia. The patient remains asymptomatic seven months after surgery.

Case Reports[McKittrick- Wheelock syndrome: report of one case].
Villous colorectal adenomas are common tumors that normally provoke scarce symptomatology. We report a 59 year-old female that was admitted with severe dehydration due to severe diarrhea lasting 10 days and vomiting in the last 48 hours. ⋯ In this patient, the fluid and electrolyte hypersecretion of the rectal villous adenoma provoked a depletion syndrome with serious hydroelectrolytic alterations, acute renal failure and hypovolemic shock. This syndrome was first described by McKittrick and Wheelock in 1954.

[Management of bleeding esophageal varices in public and private institutions in Chile].
The better treatment modalities for bleeding esophageal varices have improved the prognosis of cirrhosis. ⋯ Public health institutions have poor access to adequate diagnostic and treatment methods for esophageal bleeding. The primary and secondary prophylaxis of esophageal varices must be improved in both types of institutions.

[Prostacyclin production in internal mammary ano radial arteries and saphenous veins of diabetic and non diabetic subjects].
Myocardial revascularization surgery has used several vessels as coronary grafts including internal mammary and radial arteries which have a better prognosis than saphenous vein. Their long-term patency has been associated with the release of endothelium vasodilator and anti-aggregating products such as prostacyclin. Diabetes induces endothelial dysfunction and a high number of diabetics require revascularization. ⋯ The radial artery appears as the best replacement vessel for coronary surgery in diabetics. Its favorable biochemical profile and potential lower long-term occlusion rate may be relevant for a better prognosis of myocardial revascularization in these patients.
