RESUMEN
We describe a case of lead poisoning in a worker after hand and forearm trauma with fracture of radius and multiple fractures of metacarpal bones and hand phalanges and tissue infiltration of lead oxide (PbO) paste. Orthopedic surgery was immediately performed. After 20 days the patient had abdominal colic pain episodes and severe stipsis and blood lead level (BLL) was 60 mcg/mL with urinary lead level (ULL) of 238 mcg/24 h. After mobilization test with calcium disodium edetate were observed a high increase of BLL (180 mcg/dL) and UBL (17,000 mcg/24h). An initial anemia was observed and became severe (Hb 7.6 g/dL). A NMR exam and echography showed forearm subcutaneous lead paste infiltration and the patient underwent to a second surgical debridement with local low temperature (5 degrees C) irrigation of saline and CaNa2EDTA made the removal of the hardened lead paste. The day after, oral succimer (DMSA) chelation treatment was started with recovery of lead poison.

This multicenter study tested the actuation of a new model of pharmacovigilance, focused on three pharmacological wide-used categories (non-steroidal anti-inflammatory drugs, NSAID, oral anticoagulants, and antihypertensive drugs). Besides the traditional way of pharmacovigilance, an active investigation was performed, using a phone-structured interview. Patients discharged from the participating hospitals were included into the study, if their prescribed therapy included some of the above drugs and after informed consent. Three hundred subjects were interviewed, 100 for each pharmacological category. For a period of six months after patient's discharge from the hospital, a traditional pharmacovigilance survey was carried out. About 30 days after discharge from the hospital, patients were interviewed by the medical staff and data recorded. NSAID group stratification evidenced a significant percentage of severe haemorrhage among the patients who were using acetylsalicylic acid (ASA) as antiaggregant (6.8%) compared to the patients who were using non-ASA NSAID, at therapeutic dosage (1.8%). From this data, it seems that the active pharmacovigilance model was able to better highlight a real problem for the NSAID category, in particular it evidenced a pharmacological subclass (ASA) more prone to cause ADR than expected from literature data related to whole pharmacological class. Given the required economical effort, this pharmacovigilance method could take place as a selected tool when pharmacovigilance signals from the international databases become consistent or for new wide-used drugs, to screen potentially dangerous pharmacological subclasses, normally "hidden" because of a "camouflage" among ADRs of the entire pharmacological class.

A case of suspected high dose atropine poisoning is described. In a veterinarian good healthy young man the appearance of light coma with psychomotor agitation and the contemporary presence of evident symptoms of muscarinic peripheral block, suggesting an anticholinergic syndrome, an atropine-like intoxication in absence of toxicological analysis. The safely clinical course of the poisoning during observation in intensive care unit permitted the discharge of the patient without sequelae and without treatment with physostigmine as antidote.
