Sacroiliac (SI) joint dysfunction is a common source of chronic low-back pain. Recent evidences from different parts of the world suggest that cooled radiofrequency (RF) neuroablation of sacral nerves supplying SI joints has superior pain alleviating properties than available existing treatment options for SI joint dysfunctional pain. A 35-year-old male had intractable bilateral SI joint pain (numeric rating scale [NRS] - 9/10) with poor treatment response to intra-articular steroid therapy. Bilateral water cooled = RF was applied for neuroablation of nerves supplying both SI joints...

BACKGROUND: Refractory chronic migraine affects approximately 4% of the population worldwide and results in severe pain, lifestyle limitations, and decreased quality of life. Occipital nerve stimulation (ONS) refers to the electric stimulation of the distal branches of greater and lesser occipital nerves; the surgical technique has previously been described and has demonstrated efficacy in the treatment of a wide variety of headache disorders. OBJECTIVES: The aim of this study is to evaluate the long-term efficacy and tolerability of ONS for medically intractable chronic migraine...

Patients with lower extremity amputation (LEA) experience 65% more dermatologic issues than non-amputees, and skin problems are experienced by ≈75% of LEA patients who use prostheses. Continuously referring LEA patients to a dermatologist for every stump related skin condition may be impractical. Thus, physical rehabilitation professionals should be prepared to recognize and manage common non-emergent skin conditions in this population. The purpose of this study was to determine the quantity, quality, and strength of available evidence supporting treatment methods for prosthesis-related residual limb (RL) ulcers...

BACKGROUND: Management of chronic migraine (CM) or new daily persistent headache (NDPH) in those who require aggressive outpatient and inpatient treatment is challenging. Ketamine has been suggested as a new treatment for this intractable population. METHODS: This is a retrospective review of 77 patients who underwent administration of intravenous, subanesthetic ketamine for CM or NDPH. All patients had previously failed aggressive outpatient and inpatient treatments...

OBJECTIVE: Although surgery using a polyglycolic acid-collagen (PGA-c) tube is effective for peripheral nerve injury-induced chronic hand pain, it has not been applied to trigeminal nerve lesions because of the difficult approach. We used a PGA-c tube during surgery for trigeminal neuropathy and evaluated its prognosis based on the outcomes. DESIGN: Case report. SETTING AND PATIENTS: In the dental anesthesia division of a university hospital, 11 patients with severe dysesthesia underwent surgical repair of a damaged lingual nerve (LN) or inferior alveolar nerve (IAN)...

OBJECTIVE: Coccydynia is defined as pain in the coccygeal region. Among the many causes of coccydynia, the most common cause is trauma as a result of falling on the buttocks, repetitive microtrauma, or childbirth. Several methods are currently used for the treatment of coccydynia, including nonsteroidal anti-inflammatory drugs, intrarectal manipulation, epidural injections, ganglion impar blocks, and radiofrequency treatment (RFT). Wemm and Saberski used the transacrococcygeal methods to reduce tissue trauma...

OBJECTIVE: To use biomarkers to gain insight into and gauge the residual (post-treatment) level of inflammation in two groups of intensively treated patients with severe chronic pain. METHODS: Three study groups were analyzed, and included: (i) patients (n = 90) with chronic intractable pain (CIP), (ii) patients (n = 26) with chronic pain and MRI-documented arachnoiditis (ARC) and (iii) normal subjects without a diagnosis of chronic pain (n = 86). We determined and compared the serum concentrations of Alpha-1 Antitrypsin (A1AT), Myeloperoxidase (MPO) and soluble Tumor Necrosis Factor receptor type 2 (sTNFR2) in each of the patient populations studied...

Morphine is viewed as one of the classical treatments for intractable pain, but its role is limited by side effects, including analgesic tolerance. A few chemokines have been reported to be engaged in the mechanisms of morphine tolerance. However, the exact roles of CXCL11 in chronic morphine tolerance remain unknown. In this study, Walker 256 mammary gland carcinoma cells were inoculated into the tibia of rats to provoke cancer-induced bone pain (CIBP). Then morphine was intrathecally administered twice daily for 7 consecutive days to induce drug tolerance...

BACKGROUND: Phantom limb pain is a debilitating condition for which no effective treatment has been found. We hypothesised that re-engagement of central and peripheral circuitry involved in motor execution could reduce phantom limb pain via competitive plasticity and reversal of cortical reorganisation. METHODS: Patients with upper limb amputation and known chronic intractable phantom limb pain were recruited at three clinics in Sweden and one in Slovenia. Patients received 12 sessions of phantom motor execution using machine learning, augmented and virtual reality, and serious gaming...

Drug studies in animal models have implicated pannexin1 (Panx1) in various types of pain, including trigeminal hypersensitivity, neuropathic pain and migraine. However, the tested drugs have limited specificity and efficacy so that direct evidence for Panx1 contribution to pain has been lacking. We here show that tactile hypersensitivity is markedly attenuated by deletion of Panx1 in a mouse model of chronic orofacial pain; in this model, trigeminal ganglion Panx1 expression and function are markedly enhanced...

Hirschsprung's disease (HD) is an intestinal malformation caused by the innate absence of ganglion cells in the neural plexus of the colorectal wall, and is most common in male infants. It is rare in adult, and is usually left-sided. Herein we reported based on the CARE guidelines a case of a 47-year-old adult female suffering from "right-sided" HD complicated by refractory hypertension and cough. The patient with a history of cesarean section and with digestive unfitness (abdominal pain, distention, and constipation) only since 20 years old had recurrence of HD after initial surgery due to the incomplete removal of the HD-affected bowel based on a diagnosis of "chronic ileus", leading to the relapse of the digestive symptoms and the emergence of some intractable circulatory and respiratory complications which could be hardly controlled by conservative treatment...

IMPORTANCE: Chronic, intractable neuropathic pain is a common and debilitating consequence of neuromyelitis optica spectrum disorder (NMOSD) myelitis, with no satisfactory treatment; few studies have yet to explore its aetiology. OBJECTIVE: To establish if myelitis-associated chronic pain in NMOSD is related to the craniocaudal location of spinal cord lesions. METHOD: (1) Retrospective cohort of 76 aquaporin 4-antibody (AQP4-Ab)-positive patients from Oxford and Liverpool's national NMOSD clinics, assessing current pain and craniocaudal location of cord lesion contemporary to pain onset...

BACKGROUND: Subcutaneous peripheral nerve stimulation (PNS) has emerged as a useful tool in the treatment of intractable headaches. However, complications such as skin erosion, infection and lead migration have adversely affected clinical outcome, and occasionally led to treatment cessation. OBJECTIVES: Here we report the results of peripheral nerve stimulator implantation performed on 24 patients with various chronic headaches at our center over a period of 9 years...

Myelin basic protein (MBP) is an auto-antigen able to induce intractable pain from innocuous mechanical stimulation (mechanical allodynia). The mechanisms provoking this algesic MBP activity remain obscure. Our present study demonstrates that membrane type 1 matrix metalloproteinase (MT1-MMP/MMP-14) releases the algesic MBP peptides from the damaged myelin, which then reciprocally enhance the expression of MT1-MMP in nerve to sustain a state of allodynia. Specifically, MT1-MMP expression and activity in rat sciatic nerve gradually increased starting at day 3 after chronic constriction injury (CCI)...

BACKGROUND: Vertebral compression fractures are a common result of osteoporosis and osteopenia secondary to steroid use and chemotherapy treatment. Balloon kyphoplasty is a treatment option with good to excellent results well described in adults. Although a few recent studies have been published regarding the use of kyphoplasty in children, no formal indication exists for the pediatric population. The purpose of this study is to describe the outcomes of 3 chronically ill children with intractable pain from vertebral compression fractures, managed with kyphoplasty...

A 79-year-old female presented with incapacitating chronic neck pain. The patient's pain which was greatest on the left side persisted for 18 months and was described as stabbing in nature (10/10 intensity). In addition to her neck pain, the patient described having frequent headaches. After six weeks of physical therapy and undergoing a rhizotomy procedure, she showed no prolonged improvement. An epidural steroid injection provided only temporary pain relief and was followed by a successful posterior fusion using the Harms technique with iliac crest autogenous bone grafting and placement of polyaxial screws in the C1 lateral masses and C2 pedicles...

: An 85-year-old man developed chronic postoperative endophthalmitis after complicated cataract surgery. Visual acuity in the affected eye was hand movements. Slitlamp biomicroscopy showed a hypopyon, superonasal iris nodule, and marked vitritis. An anterior chamber washout, iris biopsy, and intravitreal amphotericin injection were performed. Panfungal polymerase chain reaction of anterior chamber and vitreous samples were positive for Penicillium citrinum. The iris biopsy showed hyphae on Grocott staining...
