Spinal Cord Stimulation in Chronic Low Back Pain Syndrome: Mechanisms of Modulation, Technical Features and Clinical Application.

Chronic low-back pain (CLBP) is a common disease with several negative consequences on the quality of life, work and activity ability and increased costs to the health-care system. When pharmacological, psychological, physical and occupational therapies or surgery fail to reduce CLBP, patients may be a candidate for Spinal Cord Stimulation (SCS). SCS consists of the transcutaneous or surgical implantation of different types of electrodes in the epidural space; electrodes are then connected to an Implanted Pulse Generator (IPG) that generates stimulating currents.

Percutaneous intradiscal injection of radiopaque gelified ethanol: short- and long-term functional outcome and complication rate in a consecutive series of patients with lumbar disc herniation.

Lumbar disc herniation (LDH) is a common cause of low back pain (LBP) and/or radicular pain (RP). Over the years, different therapies have been proposed to treat symptomatic LDH, including different minimally invasive techniques and open surgical methods. Recently, percutaneous intradiscal injection of radiopaque gelified ethanol (RGE) DiscoGel has emerged as an effective therapeutic option in patients with LDH.

Suspected Pulmonary Embolism after Oxygen-Ozone Therapy for Low Back Pain.

Oxygen-ozone therapy is used to treat degenerative pathology of the spine when surgery is not needed (e.g., removal of a herniated disk).

Occipital Nerve Stimulation for Refractory Pain after Occipitocervical Fusion.

Occipital nerve stimulation (ONS) is electric stimulation of the distal branches of the greater occipital nerve by cylindrical or paddle leads implanted in subcutaneous occipital tissue. This surgical option has emerged as a promising treatment for different types of disabling medical refractory headache and recently also for residual occipital and nuchal pain after previous occipitocervical fusion. The mechanisms of action have not yet been clearly explained: electrical stimulation of the occipital nerve has both peripheral and central effects on the nervous system, which may modulate nociception.

Occipitocervical Fusion.

Occipitocervical fusion is a surgical technique in continuous evolution due to the innovation of devices, operative and instrumentation techniques. The aetiologies responsible for occipitocervical instability are trauma, neoplastic disease, metabolic disease or congenital disease. A variety of stabilization techniques are currently available depending on the type of patient and surgeon's experience.

Administration of palmitoylethanolamide in combination with topiramate in the preventive treatment of nummular headache.

Nummular headache has been recently described as a primary disorder characterized by head pain exclusively felt in a small rounded area typically 2-6 cm in diameter, not attributed to another disorder. Both size and shape of the painful area remain constant since the onset of symptoms. A 57-year-old woman presented with a history of focal episodic pain in a circumscribed area on the right parietal region.
