The authors evaluated the role of transcranial Doppler ultrasonography (US) in patients with sickle cell disease (SCD) and cerebrovascular disease. ⋯ Transcranial Doppler US scanning has great potential as an inexpensive, easily performed screening procedure for cerebrovascular disease in patients with SCD.

To reduce the risk of accidental needle-stick injury during fine-needle aspiration biopsy, a syringe to be used in such procedures was modified. In five cases, a small hole, punctured in the barrel of a syringe above the level to which the plunger is routinely retracted, allowed the syringe to fill with air. The specimen was expressed onto a slide without the necessity of removing and reattaching the needle. This modification reduces the need to handle contaminated needles.
