Rhabdomyolysis may be secondary to trauma, excessive muscle activity, hereditary muscle enzyme defects and other medical causes. Primary hyperaldosteronism is characterised by hypertension, hypokalemia, suppressed plasma renin activity, and increased aldosterone excretion. Rhabdomyolysis is not common in primary hyperaldosteronism. ⋯ We also carried out a search of the literature to identify all cases of rhabdomyolysis as the first-recognized expression of a primary hyperaldosteronism. Sixteen cases met the criteria for inclusion. When rhabdomyolysis occurs in a patient with hypokalemia and metabolic alkalosis, primary hyperaldosteronism has to be suspected: if confirmed, an aldosterone-producing adenoma is the most probable cause.

Review Practice Guideline
[Clinical guideline for the diagnosis and treatment of subclinical thyroid dysfunction in pregnancy. Working Group on Subclinical Thyroid Dysfunction of the Spanish Endocrinology Society].
Subclinical thyroid disease is a biochemical diagnosis and is common during pregnancy. Because of the physiological hormonal changes that take place during pregnancy and the absence of normal ranges for thyroid hormones during this period, subclinical thyroid disease is difficult to interpret during pregnancy. ⋯ In contrast, subclinical hypothyroidism seems to improve with thyroxine treatment. Iodine supplements during pregnancy and lactation, even in iodine-sufficient areas, are also indicated.

Endogenous Cushing's syndrome is a very rare entity, with an incidence of 2-4 cases per million inhabitants per year. Cases caused by ectopic ACTH secretion are under-diagnosed. Cushing's disease is the most frequent cause of endogenous Cushing's syndrome, which is 5 or 6 times more frequent than adrenal Cushing's syndrome, with an incidence of between 1.2 and 2.4 cases per million inhabitants per year. ⋯ Both familial and sporadic forms exist: the familial form, or Carney complex, and ACTH-independent bilateral macronodular hyperplasia, in which the size of the adrenal glands is considerably enlarged. The signs and symptoms of Cushing's syndrome are a direct result of long-term exposure to excessive glucocorticoids. Most signs and symptoms are highly prevalent in the general population (hypertension, central obesity, diabetes mellitus or carbohydrate intolerance, osteoporosis, and characteristic phenotypical alterations).
