BACKGROUND |
This is an updated version of the original Cochrane review published in Issue 3, 2005 of The Cochrane Library. For many years antidepressant drugs have been used to manage neuropathic pain, and are often the first choice treatment. It is not clear, however, which antidepressant is more effective, what role the newer an... |
OBJECTIVES |
To determine the analgesic effectiveness and safety of antidepressant drugs in neuropathic pain. |
SEARCH STRATEGY |
Randomised controlled trials (RCTs) of antidepressants in neuropathic pain were identified in MEDLINE (1966 to Oct 2005); EMBASE (1980 to Oct 2005); the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, Issue 3, 2005; and the Cochrane Pain, Palliative and Supportive Care Trials Register ... |
SELECTION CRITERIA |
RCTs reporting the analgesic effects of antidepressant drugs in adult patients, with subjective assessment of pain of neuropathic origin. Studies that included patients with chronic headache and migraine were excluded. |
DATA COLLECTION AND ANALYSIS |
Two review authors agreed the included studies, extracted data, and assessed methodological quality independently. Sixty one trials of 20 antidepressants were considered eligible (3293 participants) for inclusion. Relative Risk (RR) and Number-Needed-to-Treat (NNTs) were calculated from dichotomous data for effectivene... |
MAIN RESULTS |
Sixty one RCTs were included in total. Tricyclic antidepressants (TCAs) are effective and have an NNT of 3.6 (95% CI 3 to 4.5) RR 2.1 (95% CI 1.8 to 2.5) for the achievement of at least moderate pain relief. There is limited evidence for the effectiveness of the newer SSRIs but no studies of SNRIs were found. Venlafaxi... |
AUTHORS' CONCLUSIONS |
This update has provided additional confirmation on the effectiveness of antidepressants for neuropathic pain and has provided new information on another antidepressant - venlafaxine. There is still limited evidence for the role of SSRIs. Whether antidepressants prevent the development of neuropathic pain (pre-emptive ... |

OBJECTIVE |
Although obesity is related with cardiovascular disease, the exact mechanism of the relationship is not fully understood. We aim to examine the relationship between plasma viscosity and obesity as a cardiovascular disease risk factor in obese and non-obese groups. |
METHODS |
We recruited 75 obese subjects (mean age: 40.2+/-8.4 years, Body Mass Index: 33.61+/-2.57 kg/m(2)) who were admitted to the Clinic of Endocrinology and Metabolism of Cerrahpasa Medical Faculty. As a non-obese group (n=70, mean age: 41.78+/-9.7 years, Body Mass Index: 21.84+/-3.42 kg/m(2)) healthy subjects from medical ... |
RESULTS |
Plasma viscosity, total cholesterol and LDL-cholesterol levels and atherogenic index were significantly increased in obese group compared to non-obese group for each p<0.001. We found no significant difference in plasma fibrinogen, insulin, albumin and HDL-cholesterol levels between obese and non-obese groups. Plasma v... |
CONCLUSION |
Plasma viscosity, an early atherosclerotic risk factor, might be helpful in the assessment of cardiovascular risk in obese subjects along with classical cardiovascular risk factors such as plasma cholesterol and atherogenic index.Lepidoptera are Relevant Bioindicators of Passive Regeneration in Tropical Dry Forests |
