ReviewAntiepileptic drugs in treatment of pain caused by diabetic neuropathy.
Pain is frequent in diabetic neuropathy and is very hard to manage. Antiepileptic drugs have been used in treating pain for several decades. Their effectiveness has been described in different types of neuropathic pain, but when used as analgesics in painful diabetic neuropathy it still remains controversial. ⋯ A combined 2.33 relative risk (95% confidence interval [CI] 1.88-2.88) was obtained; this result indicated that the antiepileptic drugs studied were effective for controlling pain in diabetic neuropathy. The corresponding necessary number to treat (NNT) values were established for evaluating which antiepileptic drug was most effective as an analgesic, according to our interests; pregabalin was shown to be the antiepileptic drug having the lowest NNT (NNT=3.24 and 95% CI 2.12-6.81) for achieving greater than 50% analgesia in patients suffering from painful diabetic neuropathy. Antiepileptic drugs are frequently used in the specific case of diabetic neuropathy; the combined result of this meta-analysis has demonstrated their analgesic benefit.

ReviewDiscrepant perceptions about end-of-life communication: a systematic review.
Little research has compared the perceptions of health professionals (HPs), patients, and caregivers about the communication of prognostic information. The objectives of this literature review were to determine 1) patient and caregiver perceptions of levels of information received about prognosis and end-of-life (EoL) issues regarding a life-limiting illness; 2) patient perceptions of and factors related to their understanding and awareness of prognosis; 3) HPs' perceptions of patients' wishes about disclosure of prognosis and factors related to their decision whether to disclose; and 4) concordance between HPs and patients/caregivers regarding the information given by HPs about prognostic and EoL issues. Relevant studies meeting the inclusion criteria were identified by searching computerized databases (MEDLINE, EMBASE, CINAHL, PsychINFO, Cochrane Register of Controlled Trials [Central]) up to November 2004. ⋯ Patients' understanding and awareness of information received conflicted with the HPs' perceptions of patients' understanding and awareness of the information that had been given. HPs tended to underestimate patients' need for information and overestimate patients' understanding and awareness of their prognosis and EoL issues. HPs need to repeatedly check patients' understanding and preferences for information.
