Transient diabetes insipidus and hypopituitarism after pituitary apoplexy: a rare association with pericardial effusion and painless thyroiditis

Pituitary apoplexy in a 38-year-old male patient with acromegaly who presented with pericardial effusion, anterior pituitary dysfunction, and diabetes insipidus is described. With corticosteroid therapy, there was good initial recovery of pituitary function and regression of pericardial effusion. On withdrawal of corticosteroids, he developed painless thyroiditis, with transient thyrotoxicosis. Subsequently, the pituitary function tests remained normal for a year, but later he gradually developed hypogonadotropic hypogonadism, hypocortisolism, growth hormone deficiency, and progressive pituitary atrophy, resulting in empty sella syndrome.

Emphysematous pyelonephritis responding to medical therapy

We describe two type 2 diabetic patients with unilateral emphysematous pyelonephritis who responded to medical treatment alone. Escherichia coli was isolated in both patients. The presence of gas was confirmed early by ultrasound and CT scan of abdomen. Following treatment, good functional recovery was demonstrable in the affected kidneys by isotope renogram. We stress the need for early diagnosis of this condition and aggressive treatment with broad spectrum antibiotics.
