The efficacy of preemptive ketamine and ropivacaine in pediatric patients: a placebo controlled, double-blind.

Objective: We have evaluated and compared the preemptive efficacy of intravenous ketamine with placebo and caudal ropivacaine in pediatric patients going under elective hernia repair.

Methods: 60 ASAI-II pediatric patients ages between 1-12. The patients were divided into 3 groups randomly.

Comparison of pulsed radiofrequency with conventional radiofrequency in the treatment of idiopathic trigeminal neuralgia.

The aim of this prospective, randomized, double-blinded study was to evaluate the effect of pulsed radiofrequency (PRF) in comparison with conventional radiofrequency (CRF) in the treatment of idiopathic trigeminal neuralgia. A total of 40 patients with idiopathic trigeminal neuralgia were included. The 20 patients in each group were randomly assigned to one of the two treatment groups.

Evaluation of antinociceptive and anti-inflammatory effects of venlafaxine in the rat.

The aim of this study was to test antinociceptive properties of venlafaxine in rats with carrageenan-induced pain and inflammation. Pain was provoked with carrageenan (1%) injection into the plantar surface of the rat paw-pad. The effect of venlafaxine on carrageenan-induced mechanical hypersensitivity, mechanical stimulation response (the von Frey monofilament test) as well as the size of carrageenan-induced paw edema were tested at 2 to 24 hours following the toxin injection into the rat paw-pad.

[Percutaneous lumber nucleoplasty].

Low-back pain is one of the most common causes for seeking professional medical assistance and the most frequent cause of absence from work. It is not rare that the intervertebral discs are the etiological factor. Degenerated discs with internal disruptions may cause axial back pain whereas protrusion or herniation of a disc may result in radicular pain.

[Sacral nerve stimulation in fecal incontinence; efficacy and safety].

Fecal incontinence is common due to various reasons. Conservative therapy of fecal incontinence may sometimes be effective in improving function, but usually many patients require surgery. Sacral nerve stimulation is another treatment modality which gained interest, and appears to be an alternative method that is successful with low morbidity.
