In this single centre study, the clinical pharmacists identified and intervened on a high number of severe medication errors. This suggests that emergency services will benefit from pharmacist-provided drug therapy services.

Introduction Nelarabine is a purine analogue approved for the treatment of patients with T-cell lymphoblastic lymphoma and T-cell acute lymphoblastic leukaemia (T-ALL) that have relapsed or are refractory to two previous chemotherapy regimens. Adverse reactions to nelarabine include neurological toxicity, the pathophysiological mechanisms of which are unknown, although the administration of intrathecal therapy at therapeutic doses given concomitantly with high-dose systemic chemotherapy that crosses the blood–brain barrier may potentiate neurotoxicity. Case report We report a case of a 29-year-old woman with a diagnosis of relapsed T-ALL who developed severe myelopathy and polyneuropathy of toxic origin that led to paraplegia, upper-limb paresis, and dysautonomia after the first cycle of nelarabine. Management and outcome Rehabilitation and pharmacological treatments were initiated early, but no evidence of a significant clinical change was obtained. Discussion Neurotoxicity is a dose-dependent side effect of nelarabine. It is therefore important to consider previously administered neurotoxic drugs before using nelarabine and to monitor patients closely so as to be able to act promptly in case of toxicity. In accordance with the data obtained and based on the Naranjo algorithm, the adverse reaction could be considered possible.

Everolimus is an immunosuppressant agent used in organ transplantation and, more recently, in cancer therapy. It has demonstrated beneficial effects in breast cancer, renal cancer, and neuroendocrine tumours. However, the treatment is not without side effects, some of which are still little known. We report the case of a 56 year-old man with a diagnosis of neuroendocrine tumour who developed a complex regional pain syndrome (CRPS) secondary to treatment with everolimus. CRPS has been linked to treatments with everolimus in renal and breast cancer patients as well as in renal transplant patients. To our knowledge, this is the first case of CRPS in a neuroendocrine tumour patient on everolimus treatment.

ObjectivesTo describe a clinical pharmacist’s (CP) activity in an emergency department (ED) regarding medication reconciliation and optimisation of pharmacotherapy of patients at hospital admission.MethodsA 1-year prospective observational study was conducted to analyse the activity of a CP in the ED of a 350-bed hospital in Spain. The CP reviewed home medications and medical prescriptions of patients to perform medication reconciliation if required and intervene if medication errors were detected.ResultsThe CP reviewed medications and medical orders of 1048 patients. 816 patients had home medication: 440 patients (53.9%) were correctly reconciled by the physician; 136 (16.7%) were reconciled by the physician with unintentional discrepancies; and 240 (29.4%) by the CP, with a higher percentage in patients admitted to surgical departments (χ2:38.698; P<0.001). Following pharmaceutical validation, 434 pharmaceutical interventions were performed.ConclusionsThe presence of a CP in an ED could increase the detection of reconciliation errors and help resolve medication errors.
