RESUMO
The use of lead shotgun ammunition for hunting has been banned in a few jurisdictions and habitats, principally to protect wild birds from poisoning by ingestion of spent lead shot. The EU and UK REACH processes have recently considered bans on lead ammunition throughout the European Union and United Kingdom, including assessments of possible health benefits from reduced human dietary exposure to lead from game meat. Comparisons of the mean lead concentrations in meat from gamebirds killed using lead and nonlead shotgun ammunition have not been published. We compared lead concentrations in meat from wild-shot pheasants from which lead shotgun pellets were recovered (n = 27) with those from which iron pellets were recovered (n = 20), having removed all pellets from the meat before analysis. The mean concentration of lead in meat from pheasants killed using lead shot was 2.10 mg/kg w.w., which is >20 times the European Union's maximum permitted level for the lead concentration in meat from domesticated animals. For pheasants killed using iron shot the mean was 0.07 mg/kg w.w., which is below the maximum permitted level.

Oncocytic neoplasms are most rarely found in the adrenal gland. They are usually benign and non-functioning. We present a case of a testosterone-secreting oncocytic adrenocortical carcinoma in a 19-year-old female who presented with acne, hirsutism and irregular menses. Clinical investigations revealed an elevated testosterone and DHEA-S and a 4×5 cm left adrenal mass. The tumour was successfully excised. The histology showed the tumour to be comprised of oncocytic cells with granular, eosinophilic cytoplasm, features consistent with an oncocytic carcinoma. This is the first case presented of a testosterone-secreting oncocytic adrenocortical carcinoma.
