Coexistencia de hiperparatiroidismo primario y carcinoma diferenciado del tiroides en tres casos clínicos / Coexistence of a primary hyperparathyroidism and a differentiated thyroid carcinoma: report of three cases

In 15 percent of patients with primary hyperparathyroidism subjected to parathyroid surgery, a coexistent differentiated thyroid carcinoma is found. We report three female patients aged 57, 53 and 57 years with a primary hyperparathyroidism and ultrasonographic thyroid nodules. During parathyroid surgery, a thyroidectomy was performed, confirming the presence of a differentiated thyroid carcinoma. Two patients had a microcarcinoma measuring 1 and 2 mm diameter and other had a follicular thyroid carcinoma, and parathyroid carcinom whose association with primary hyperparathyoidism is even more uncommon.

Hemibalismo invalidante transitorio como debut de diabetes mellitus / Transient hemiballism as the presenting symptom of diabetes mellitus: report of one case

Hemiballism is an uncommon neurological disorder characterized by uncontrollable movements of one lateral half of the body. We report a 56 years old male with a history of three weeks of polydipsia, polyuria and weight loss that, three days before consultation, started with hemiballism. A CAT scan without contrast showed a higher density in the lenticular nucleus and calcifications in caudate and lenticular nuclei. Diabetes was treated with regular insulin and hemiballism was controlled with neruoleptics. Ten days after admission a new CAT scan shows a partial regression of the lenticular lesion. After two months of follow up, the patient is asymptomatic.
