The evolutionary pattern of the different parameters studied in our patients with FBSS does not differ according to their treatment by spinal stimulation, with conventional or high frequency, in one year follow-up.

The optimal therapy for vulvar pain syndrome remains elusive, with low percentages of therapeutic success, using either local or systemic pharmacological approaches. Surgery involving invasive and often irreversible therapeutic procedures has resulted in success for certain subtypes of vulvodynia. We present a multidisciplinary approach whereby pain treatment units may provide an intermediate level of care between standard medical and surgical treatments.

On the basics of our own experience and on the analysis of the reports published in the literature, fractioned subcutaneous injections of botulinum toxin may be useful for the treatment of various chronic localized pain conditions including chronic post-thoracotomy pain.

On the basis of the analysis of the reports published in the literature, it would seem that fractioned peripheral subcutaneous and perineural injections of botulinum toxin type A may be useful for the treatment of various chronic pain conditions with neuropathic component.

Ketamine has been shown to be effective in the treatment of neuropathic pain. We present a case of severe complex regional pain syndrome type 1 that was treated with oral ketamine. The response and tolerability of this preparation suggest that further study is warranted.
