Health assessment of phosgene: approaches for derivation of reference concentration.

This paper describes the derivation of the chronic reference concentration (RfC) for human inhalation of phosgene that was recently added to the Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) data base (U.S. EPA, 2005.

Rare case of recurrent angiokeratoma of Fordyce on penile shaft.

Angiokeratomas are benign cutaneous vascular lesions characterized by dilated thin-walled blood vessels lying in the upper part of the dermis, mostly associated with an epidermal reaction such as acanthosis and/or hyperkeratosis. Angiokeratomas of Fordyce are predominantly located on the scrotum and are only rarely found on the penis and then usually on the glans penis. We report a rare case of angiokeratoma of Fordyce located on the shaft of the penis and associated with two recurrences after appropriate surgical excision.

Early recurrence of primary focal segmental glomerulosclerosis in an older cadaveric renal allograft recipient resistant to plasmapheresis.

We report an unusual case of recurrent primary focal segmental glomerulosclerosis in an apparent low-risk cadaveric renal allograft recipient only 2 days after transplantation, who did not respond to repeated courses of plasmapheresis.

Can the outcome of older donor kidneys in transplantation be predicted? An analysis of existing scoring systems.

The use of older cadaveric donors in kidney transplantation is increasing. The transplant outcome of the single older kidney is generally inferior prompting some to recommend dual kidney transplantation. The ability to predict the outcome of the solitary marginal kidney becomes clinically important.
