Pregnancy is known to aggravate pre-existing chronic painful conditions. Trigeminal neuralgia (TN), albeit a disease of elderly may afflict pregnant females which can further complicate its management. Teratogenic effects of the commonly used drugs on the developing fetus limit pharmacological treatment. Moreover safety of commonly performed interventional therapies is marred by their inherent fetomaternal effects and more importantly the risk of radiation effects on fetus due to the use of fluoroscopy. This rare coexistence of TN in pregnancy is never reported before...

Temporomandibular disorder (TMD) is a very wide term which includes a variety of clinical issues related to the masticatory muscles, the temporomandibular joint (TMJ), and their associated structures (1) . For TMD patients the main concern is pain, and it is the most common reason for medical consultation; but pain makes also a great challenge for clinicians (2) . In fact, dysfunction of the central nervous system when processing nociceptive input has been stated as a factor involved in the onset and maintenance of pain in patients with chronic TMD (3) This article is protected by copyright...

INTRODUCTION: Superior hypogastric plexus block (SHGPB) is technically difficult and accurate procedure is required to avoid potential complications. We attempted to determine the reference angles for fluoroscopy-assisted SHGPB and to establish a predictor that can guide to select optimal approach between classic posterior approach and transdiscal approach. METHODS: Abdomino-pelvic CT scans from 268 patients diagnosed with pelvic malignancies were examined. The oblique and axial angles needed for the fluoroscope were measured both for posterior and transdiscal approaches by simulating the needle trajectory on CT imaging...

BACKGROUND AND OBJECTIVES: Intrathecal targeted drug delivery systems historically required a physician's office visits for dose adjustment to manage fluctuating pain. A wireless device now enables patients to supplement their basal intrathecal infusion with a programmed on-demand bolus dose. We sought to quantify the change in oral breakthrough opioid need associated with the use of an intrathecal bolus in comparison to those treated with the basal infusion alone. METHODS: Demographic, dosage, bolus usage and longevity data were extracted from the historical medical record of 69 patients (18/51 bolus/non-bolus) followed continuously at our center...

BACKGROUND: Efficacy of pain assessment is the basis for effective therapy. Clinically, assessing pain is by subjective scale, but these methods have some shortcomings. Therefore, studies have been conducted on assessment of pain using physiological signals. Photoplethysmography (PPG) signal provides much information about the cardiovascular system. PPG- derived parameters (PPG parameters) reflect nociceptive stimulation, and obtain an approximation of the R-R interval from PPG period...

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: Parent interactions with their child can influence the child's pain and distress during painful procedures. Reliable and valid interaction analysis systems (IASs) are valuable tools for capturing these interactions. The extent to which IASs are used in observational research of parent-child interactions is unknown in pediatric populations. OBJECTIVES: To identify and evaluate studies that focus on assessing psychometric properties of initial iterations/publications of observational coding systems of parent-child interactions during painful procedures...

OBJECTIVES: Central sensitization (CS) implies increased sensitivity of the nervous system, resulting in increased pain sensitivity as well as widespread pain. Recently, the Central Sensitization Inventory (CSI) was developed to assess symptoms of CS and central sensitivity syndromes. The aim of this study was to examine the convergent validity of the CSI by comparing the outcome to psychosocial factors and clinical features of CS. METHODS: In a cross-sectional explorative study, patients with chronic pain completed multiple questionnaires, including the CSI, pain catastrophizing scale, SCL-90 for psychological distress, duration of pain, intensity of pain, widespread pain, and lateralization of pain...

BACKGROUND: Pressure algometry is a commonly employed technique in the assessment of both regional and widespread musculoskeletal pain. Despite its acceptance amongst clinicians and scientists, the relationship between rate of pressure application (RoA) and pain pressure threshold (PPT) remains poorly understood. We set out to test the hypothesis that a strong, positive, linear relationship exists between the RoA and the PPT within the infraspinatus of young healthy subjects. METHODS: Thirty-three (n=33) participants were randomly recruited from the local university community...

Sleep problems are common in people with low back pain (LBP), however the mechanisms on how sleep influences pain are complex. To date there is a lack of prospective research on the timings and the development of sleep problems in those who have LBP, such information would be useful to identify individuals at risk of poor outcome. Aims are to investigate the predictive role of sleep problems on self-report recovery and pain intensity using logistic regression reporting Odds Ratios (OR). An observational cohort of 761 chronic LBP patients recruited from a pain management clinic participated, and completed data at baseline, and at 6 month follow-up (n = 682)...

BACKGROUND AND AIM: The Pain Sensitivity Questionnaire (PSQ), a self-reported scale, has been used to assess the pain sensitivity level in a Caucasian population. However, a validated Mandarin Chinese version of the PSQ is not available. This study was aimed to translate the PSQ into Mandarin Chinese (PSQ-C) and validate it to measure pain sensitivity among Chinese people. METHODS: The English version of the PSQ has been translated into Mandarin Chinese (PSQ-C), according to the standard steps of cross-cultural adaptation of self-reported scales...

BACKGROUND: There is a growing interest in the role of disturbed body perception in people with persistent pain problems such as chronic low back pain (CLBP). A questionnaire, the Fremantle Back Awareness Questionnaire (FreBAQ), was recently developed as a simple and quick way of assessing disturbed perceptual awareness of the back in people with CLBP and appears to have acceptable psychometric properties. The aim of the present study was to develop a Japanese version of the FreBAQ (FreBAQ-J) and evaluate its psychometric properties in a sample of Japanese people with low back pain (LBP)...

Limb amputation is sometimes being performed in long-standing complex regional pain syndrome (CRPS), although little evidence is available guiding management decisions, including how CRPS recurrence should be managed. This report details the management of a young soldier with CRPS recurrence 2 years after midtibial amputation for CRPS. Conventional spinal cord stimulation did not achieve paraesthetic coverage, or pain relief in the stump, whereas L4 dorsal root ganglion stimulation achieved both coverage and initially modest pain relief, and over time, substantial pain relief...
