An 11-month-old boy had an episode of generalized convulsions followed by a right peripheral facial palsy, which resolved gradually within 3 weeks. Three months later he had another similar episode of convulsions followed by a left peripheral facial palsy. On both occasions it was found that he had polycythaemia. A careful physical examination discovered that the child had severe hypertension. Extensive laboratory investigations did not reveal a cause for his hypertension. Haematologic investigations showed that the polycythaemia was due to a contracted plasma volume as a result of the hypertension. The peripheral facial palsy most probably was due to a blood clot in the facial canal, below the origin of the nerve to m. stapedius, as audiograms were normal and lacrimation preserved. Control of the hypertension resulted in resolution of the facial palsy within 4 weeks and normal haematocrit readings within 6 weeks. It should be stressed that every patient with peripheral facial palsy should be examined for hypertension.

Post-transplant (Tx) hypertension (H) is extremely cormnon amng pediatric renal transplant recipients, occurring in 83% of ur first 86 patients. In order to study H free of known conomitant causes, we studied those 16 of the 86 consecutive Tx in horn there had never been any rejection episode nor any recurrent isease. Follow-up period was 1-5 years. Patients (P) ranged in ge from 3 to 24 years (median 16). All 16 P were hypertensive n the first post-operative week.Nine P, all with various nephritides, had H pre-Tx, leading to re-Tx nephrectomies (Nx) in 5. Post-Tx, all 9 were hypertensivt uring the first 6 months (2mild H. 7moderate H). By one
