Renovascular hypertension in children.

Renal arteriography remains the only study to identify and define correctly both location and extent of renal artery stenosis. Because other studies do not adequately identify all children who have renal artery disease, it is reasonable to perform renal arteriography in those children with severe hypertension who do not have another readily identifiable cause for their hypertension. On the other hand, in children with less profound elevation of blood pressure in whom there is no other definable cause, it is possible to defer renal angiography.

Psychogenic intractable sneezing in children.

Four preadolescent children had paroxysms of intractable sneezing. After days of hospitalization and numerous local and systemic drug treatments had failed, a psychogenic cause of their problem was entertained. This uncommon form of conversion reaction most often occurs between the ages of 9 and 15 years, and prognosis is good if the appropriate interventions are undertaken.
