Three cases of ocular syphilis and the resurgence of the disease in Queensland.

The past few years has seen a resurgence of syphilis. It is predominantly associated within men who have sex with men and also within heterosexual Indigenous Australians. Possessing the ability to mimic a variety of ocular diseases, it typically manifests as uveitis, although it can affect any structure within the eye.

Low- and standard-dose corticotropin and insulin hypoglycemia testing in the assessment of hypothalamic-pituitary-adrenal function after pituitary surgery.

The optimal means of assessing the integrity of the hypothalamic-pituitary-adrenal (HPA) axis after pituitary surgery remains controversial. We compared low-dose (1 micro g iv) and standard-dose (250 micro g im) corticotropin tests performed 1 and 4-6 wk after pituitary surgery with an insulin hypoglycemia test performed at 4-6 wk. Forty-one patients (21 male and 20 female; median age, 52 yr; range, 23-73 yr) who had undergone pituitary surgery were studied (Cushing's disease excluded).
