abstract cisplatin was the first of the platinum drugs. second-generation platinum derivative was carboplatin that its efficacy in the treatment of many malignancies is equal to cisplatin, and its toxicity profile is more favorable. here we report on a 50-year-old woman with a history of cervix cancer who developed a severe hypersensitivity reaction (hsr) to carboplatin. she was admitted to the...

the cross efficiency evaluation is used to performance measurement of decision making units in data envelopment analysis concept. one of the most important shortcoming of this method is existing alternative optimal solution and therefore, the efficiency scores are not unique. we are going to summarize the pervious models proposed by researchers and suggest an alternative secondary goal approach...
