BACKGROUND: The effective management of pain in chronic pancreatitis (CP) remains a therapeutic challenge. Analgesic drugs, such as opioids, and the underlying pathology can impair gut function. The autonomic nervous system influences hormone secretion and gut motility. In healthy volunteers, electrical (using noninvasive transcutaneous vagal nerve stimulation [t-VNS]) and physiological (using deep slow breathing [DSB]) modulation of parasympathetic tone results in pain attenuation and enhanced gut motility...

PURPOSE OF REVIEW: To provide an update on nonsurgical and nonpharmacologic strategies for the management of chronic pelvic pain (CPP). RECENT FINDINGS: Effective treatment of patients with CPP requires a multifaceted approach, with thoughtful consideration of surgical, pharmacologic, and nonpharmacologic strategies. Evidence for physical therapy and trigger point injections for treatment of myofascial components of CPP is increasing. Neuromodulation techniques, such as percutaneous tibial nerve stimulation and transcutaneous electrical stimulation, have limited but favorable preliminary data in patients with CPP...

Objective To review the clinical entity of primary burning mouth syndrome (BMS), its pathophysiological mechanisms, accurate new diagnostic methods and evidence-based treatment options, and to describe novel lines for future research regarding aetiology, pathophysiology, and new therapeutic strategies. Description Primary BMS is a chronic neuropathic intraoral pain condition that despite typical symptoms lacks clear clinical signs of neuropathic involvement. With advanced diagnostic methods, such as quantitative sensory testing of small somatosensory and taste afferents, neurophysiological recordings of the trigeminal system, and peripheral nerve blocks, most BMS patients can be classified into the peripheral or central type of neuropathic pain...

BACKGROUND: Headache is one of the most common conditions troubling nearly 45% of the world's population. Migraine headache itself, being more common among women, affects 7-18% of people. As much as 20-30% of the population report accompanying aura and neurological symptoms. In many cases, migraine headache can be effectively treated with suitably selected pharmacotherapies which include drugs used in symptomatic treatment. Frequent occurrence of the condition is treated with prophylaxis, which often fails...

Chronic or neuropathic trigeminal facial pain can be challenging to treat. Neurosurgical procedures should be applied when conservative treatment fails. Neuromodulation techniques for chronic facial pain include deep brain stimulation and motor cortex stimulation, which are complex to perform. Subcutaneous nerve field stimulation is certified for chronic back pain and is the least invasive form of neuromodulation. We applied this technique to treat chronic and neuropathic trigeminal pain as an individual therapy concept...

INTRODUCTION: Chronic low back pain affects millions of people worldwide and can arise through a variety of clinical origins. In the case of Failed Back Surgery Syndrome (FBSS), previous surgical procedures can contribute to low back pain that is often unresponsive to intervention. Although spinal cord stimulation can be an effective treatment modality, it does not provide sufficient pain relief for some intractable cases. Recently, alternative neuromodulation options have been developed, including dorsal root ganglion (DRG) stimulation...

BACKGROUND: Recent evidence suggests that chronic low back pain is associated with plastic changes in the brain that can be modified by neuromodulation strategies. This study investigated the efficacy of transcranial direct current stimulation (tDCS) combined simultaneously with peripheral electrical stimulation (PES) for pain relief, disability and global perception in patients with chronic low back pain (CLBP). METHODS: Ninety-two patients with CLBP were randomized to receive 12 sessions on nonconsecutive days of anodal tDCS (primary motor cortex, M1), 100 Hz sensory PES (lumbar spine), tDCS + PES or sham tDCS + PES...

Neuromodulatory techniques have replaced the earlier performed neurolesional procedures to treat chronic pain syndromes with only a few exceptions. Nevertheless these procedures are invasive with respective risks and complications and therefore conservative physical, psychological pharmacological as well as interventional treatments should be performed first. Because this therapy is costly, the indication has to be proven carefully with a strict patient selection and also the long-term results have to be considered...

OBJECTIVE: The experience with deep brain stimulation (DBS) for pain is largely based on uncontrolled studies targeting the somatosensory pathways, with mixed results. We hypothesized that targeting limbic neural pathways would modulate the affective sphere of pain and alleviate suffering. METHODS: We conducted a prospective, double-blinded, randomized, placebo-controlled, crossover study of DBS targeting the ventral striatum/anterior limb of the internal capsule (VS/ALIC) in 10 patients with poststroke pain syndrome...

Excision of all endometriotic lesions is the method of choice in the treatment of severe endometriosis resistant to medical therapy. The infiltrating nature of the disease as well as extensive surgery may, however, cause chronic pain that cannot be relieved by either surgery or hormonal treatment. As a pilot treatment, we tested the effect of sacral neuromodulation (SNM) for four endometriosis patients suffering chronic pelvic pain and pelvic organ dysfunction after radical surgical treatment. Three out of four patients reported improvement in their symptoms during the neuromodulation testing period and a permanent pulse generator was installed...

Neuropathic pain is a common cause of disability and health care utilization. While judicious pharmacotherapy and management of comorbid psychological distress can provide for improved quality of life, some patients with treatment-refractory disease require more invasive therapies. Spinal cord stimulation can provide for improvement in pain and decrease in medication utilization, with level 1 evidence supporting its use across various pain etiologies including persistent postoperative neuropathic pain, complex regional pain syndrome, chronic inoperable limb ischemia, treatment refractory angina, and painful diabetic neuropathy...

Patients with functional GI disorders (FGIDs) are commonplace in the gastroenterologist's practice. A number of these patients may be refractory to peripherally acting agents, yet respond to central neuromodulators. There are benefits and potential adverse effects to using TCAs, SSRIs, SNRIs, atypical antipsychotics, and miscellaneous central neuromodulators in these patients. These agents can benefit mood, pain, diarrhea, constipation, nausea, sleep, and depression. The mechanisms by which they work, the differences between classes and individual agents, and the various adverse effects are outlined...
