Gout is clinically characterized by episodes of monoarthritis, which not only typically affects the peripheral joints but also occasionally affect the axial joint, such as the sacroiliac joint (SIJ), and often mimics spondyloarthritis (SpA). Two cases of gout mimicking SpA are presented in the current paper. One patient was a 32-year-old man with a history of asymmetrical oligoarthritis of ankle and metatarsophalangeal joints (MTPJ). He had left gluteal pain for 2 weeks. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed the bone erosion of the left SIJ...

REVIEW
Sanjay Prakash, Payal Patel
Hemicrania continua (HC) is an indomethacin-responsive primary headache disorder which is currently classified under the heading of trigeminal autonomic cephalalgias (TACs). It is a highly misdiagnosed and underreported primary headache. The pooled mean delay of diagnosis of HC is 8.0 ± 7.2 years. It is not rare. We noted more than 1000 cases in the literature. It represents 1.7% of total headache patients attending headache or neurology clinic. Just like other TACs, it is characterized by strictly unilateral pain in the trigeminal distribution, cranial autonomic features in the same area and agitation during exacerbations/attacks...

BACKGROUND: The role of thoracic paravertebral blockade (TPVB) in decreasing opioid requirements in breast cancer surgery is well documented, and there is mounting evidence that this may improve survival and reduce the rate of malignancy recurrence following cancer-related mastectomy. We compared the two techniques currently in use at our institution, the anatomic landmark-guided (ALG) multilevel versus an ultrasound-guided (USG) single injection, to determine an optimal technique. METHODS: We retrospectively reviewed records of patients who received TPVB from January 2013 to December 2014...

OBJECTIVE: Patients with chronic fatigue syndrome (CFS) complain of long-lasting fatigue and pain which are not relieved by rest and worsened by physical exertion. Previous research has implicated metaboreceptors of muscles to play an important role for chronic fatigue and pain. Therefore, we hypothesized that blocking impulse input from deep tissues with intramuscular lidocaine injections would improve not only the pain but also fatigue of CFS patients. METHODS: In a double-blind, placebo-controlled study, 58 CFS patients received 20 mL of 1% lidocaine (200 mg) or normal saline once into both trapezius and gluteal muscles...

BACKGROUND: Current Danish treatment algorithms for pharmacological treatment of neuropathic pain (NeP) are tricyclic antidepressants (TCA), gabapentin and pregabalin as first-line treatment for the most common NeP conditions. Many patients have insufficient pain relief on monotherapy, but combination therapy had not been included in guidelines until recently. Based on clinical empiricism and scientific evidence, a Delphi consensus process provided a consolidated guidance on pharmacological combination treatment of NeP...

BACKGROUND AND OBJECTIVE: Initial peripheral/central nerve injuries, such as chronic constriction injury (CCI)/spinal cord injury, are often compounded by secondary mechanisms, including inflammation and oxidative stress, which may lead to chronic neuropathic pain characterized by hyperalgesia or allodynia. On the other hand, exercise as a behavioral and non-pharmacological treatment has been shown to alleviate chronic neuropathic pain. Therefore, this study was conducted to examine whether or not exercise reduces neuropathic pain through modifying oxidative stress and inflammation in chronic constriction injury of the sciatic nerve...

BACKGROUND: The first description of epicrania fugax (EF) reported brief painful paroxysms that start in posterior regions of the scalp and move forward to reach the ipsilateral forehead, eye, or nose. A backward variation, wherein pain stems from frontal areas and radiates to the posterior scalp, has also been acknowledged. We report four patients with features reminiscent of EF and the coexistence of forward and backward pain paroxysms. METHODS: We considered all patients attending the headache outpatient office at two tertiary hospitals from March 2008 to March 2016...

BACKGROUND: Pain is one of the factors that decrease quality of life. Undergoing surgery is inevitably associated with the sensation of pain, which can affect a patient's level of acceptance of an illness. The aim of the study was to evaluate the level of acceptance of illness in patients undergoing surgical treatment with relation to the pain perceived by them during surgical treatment and to determine other factors that affect adaptation to illness among patients subjected to invasive treatment...

According to the dual process model of coping, assimilative or accommodative strategies can be applied to deal with aversive life situations. In people with chronic pain, the tenacious focus on achieving analgesia is often referred to as assimilative coping and associated with more disability and catastrophic thinking. In contrast, accommodative coping (accepting one's pain and setting new goals) appears to have beneficial effects. To assess how people with chronic pain use these different coping strategies, questionnaires measuring these concepts are needed...

OBJECT: Entrapment of the middle cluneal nerve (MCN) under the long posterior sacroiliac ligament (LPSL) is a possible, and underdiagnosed, cause of low-back and/or leg symptoms. To date, detailed anatomical studies of MCN entrapment are few. The purpose of this study was to ascertain, using cadavers, the relationship between the MCN and LPSL and to investigate MCN entrapment. METHODS: A total of 30 hemipelves from 20 cadaveric donors (15 female, 5 male) designated for education or research, were studied by gross anatomical dissection...

Caudal epidural injection (CEI) is one of the most common treatments for low-back pain with sciatica. CEI rarely leads to neurologic complications. We report a case of persistent cauda equina syndrome after CEI. A 44-year-old male patient with severe L4 and L5 spinal ste-nosis underwent CEI for low-back pain and sciatica. The CEI solution consisted of bupivacaine, hyaluronidase, triamcinolone acetonide, and normal saline. He experienced motor weakness and sensory loss in both lower extremities and neurogenic bladder for more than 1 year after the procedure...

PURPOSE: To develop a clinical score to discriminate patients with somatic symptom disorder (SSD) from those with medical disease (MD) for complaints of non-acute pain. METHODS: We retrospectively examined the clinical records of consecutive patients with pain for a duration of ≥1 month in our department from April 2003 to March 2015. We divided the subjects according to the diagnoses of definite SSD (as diagnosed and tracked by psychiatrists in our hospital), probable SSD (without evaluation by psychiatrists in our hospital), matched MD (randomly matched two patients by age, sex, and pain location for each definite SSD patient), unmatched MD, other mental disease, or functional somatic syndrome (FSS)...

Spinal cord injury (SCI) complicated by epidural anesthesia, though rare, can result in neuropathic pain. However, the treatment for this kind of life-altering injury remains a challenge. A 7-year-old girl was referred with dyskinesia and severe pain in her right lower extremity due to an accidental SCI following lumbar puncture. After treatment with analgesics such as gabapentin, mecobalamin, and dexamethasone/methylprednisolone for 1 week, the myodynamia had improved, but progressive pain persisted. After treatment with neurotropin, a gradual decrease in visual analog scale score from 7 to 0 was observed...

Chronic pain represents a common public health concern worldwide. It is a complex phenomenon, owing to the interaction of different factors, including biological, physiological, psychological, environmental, and social variables. Some groups, such as women and immigrants, are particularly vulnerable. However, little is known about how Chinese women in Italy live with and face chronic pain. The present study aimed at filling this knowledge gap by examining the burden of chronic pain in Chinese immigrants in Italy in terms of acculturation processes, perceived control over disease, social networks, and coping strategies...

Lower back pain (LBP) is a global public health issue and is associated with substantial financial costs and loss of quality of life. Over the years, different literature has provided different statistics regarding the causes of the back pain. The following statistic is the closest estimation regarding our patient population. The sacroiliac (SI) joint pain is responsible for LBP in 18%-30% of individuals with LBP. Quadrapolar™ radiofrequency ablation, which involves ablation of the nerves of the SI joint using heat, is a commonly used treatment for SI joint pain...

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...
