PURPOSING: The Central Sensitization Inventory (CSI) is a new patient-reported instrument, which measures symptoms related to Central Sensitivity Syndromes and Central Sensitization. The aim of this study was to translate the CSI into Spanish, and then to perform a psychometric validation, including a factor analysis to reveal the underlying structure. METHODS: In this two-stage psychometric study participated 395 subjects with various chronic pain conditions and that were recruited from two Primary Care Centres...

The central sensitization syndrome (CSS) encompasses disorders with overlapping symptoms in a structural pathology spectrum ranging from persistent nociception [e.g., osteoarthritis (OA)] to an absence of tissue injuries such as the one presented in fibromyalgia (FM) and myofascial pain syndrome (MPS). First, we hypothesized that these syndromes present differences in their cortical excitability parameters assessed by transcranial magnetic stimulation (TMS), namely motor evoked potential (MEP), cortical silent period (CSP), short intracortical inhibition (SICI) and short intracortical facilitation (SICF)...

AIMS: Mechanisms underlying pain perception and afferent hypersensitivity, such as central sensitization, may impact overactive bladder (OAB) symptoms. However, little is known about associations between OAB symptom severity, pain experience, and presence of comorbid chronic pain syndromes. This study examined relationships between OAB symptoms, somatic symptoms, and specific chronic pain conditions in which central sensitization is believed to play a primary role, in a community-based sample of adult women with OAB...

Globally, 8 of the top 12 disabling conditions are related either to chronic pain or to the psychological conditions strongly associated with persistent pain. In this narrative review, we explore the demographic and psychosocial associations with chronic pain exclusively from low- and middle-income countries (LMICs) and compare them with current global data. One hundred nineteen publications in 28 LMICs were identified for review; associations with depression, anxiety, posttraumatic stress, insomnia, disability, gender, age, rural/urban location, education level, income, and additional sites of pain were analyzed for each type of chronic pain without clear etiology...

Fibromyalgia syndrome (FMS) is a clinical disorder predominant in females with unknown etiology and medically unexplained symptoms (MUS), similar to other afflictions, including irritable bowel syndrome (IBS), chronic fatigue syndrome (CFS), post-traumatic stress disorder (PTSD), Gulf War illness (GFI), and others. External environmental stimuli drive behavior and impact physiologic homeostasis (internal environment) via autonomic functioning. These environments directly impact the individual affective state (mind), which feeds back to regulate physiology (body)...

OBJECTIVES: The aim of this study was to create and validate severity levels for the central sensitization inventory (CSI), a valid and reliable patient-reported outcome instrument designed to identify patients whose presenting symptoms may be related to a central sensitivity syndrome (CSS; eg, fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome), with a proposed common etiology of central sensitization (CS). METHODS: Based on CSI score means and standard deviations from previously published subject samples, the following CSI severity levels were established: subclinical = 0 to 29; mild = 30 to 39; moderate = 40 to 49; severe = 50 to 59; and extreme = 60 to 100...

UNLABELLED: The most common cause of chronic oro-facial pain is a group of disorders collectively termed temporomandibular disorders (TMDs). Chronic painful TMD is thought to be a 'central sensitivity syndrome' related to hypersensitivity of the nervous system, but the cause is unknown. A similar understanding is proposed for other unexplained conditions, including chronic fatigue syndrome (CFS). Exploring the comorbidity of the two conditions is a valuable first step in identifying potential common aetiological mechanisms or treatment targets...

CONCLUSIONS: The feelings of dizziness and unsteadiness of the patients with fibromyalgia supposed specifically amplified by the hypersensitivity mechanism of CSS (central sensitivity syndrome) of them. The severity of subjective pain and physical distress according to the questionnaires were not correlated with the objective body sway on the stabilometer. OBJECTIVES: Fibromyalgia manifests primarily as chronic pain of the entire body, but is also often associated with a variety of physical symptoms including dizziness and unsteadiness...

Women who carry fragile X mental retardation 1 (FMR1)gene premutation expansions frequently report neurological or endocrine symptoms and prior studies have predominantly focused on questionnaire report of medical issues. Premutation carrier (PMC) women (n = 33) and non-carrier controls (n = 13) were recruited and evaluated by a neurologist, neuropsychologist, and endocrinologist. Blood and skin biopsies were collected for molecular measures. Scales for movement disorders, neuropathy, cognitive function, psychiatric symptoms, sleep, and quality of life were completed...

Central sensitization (CS), simply defined as an amplified response of the central nervous system to peripheral input, is a concept of great importance in clinical medicine. It has helped to explain aspects of the pathophysiology of common diseases, e.g. fibromyalgia syndrome (FMS), irritable bowel syndrome, vulvodynia, headaches, chronic pelvic pain and other overlapping conditions (collectively called central sensitivity syndromes, or CSS). It also applies to pain of complex regional pain syndrome, osteoarthritis (OA), rheumatoid arthritis (RA) and post-operative pain...

The nervous system as well as the immune system use common signaling molecules for intra- and inter-system communications. Specifically, both entities produce a similar array of peptide and non-peptide transmitters that act on a common set of receptors present in the two systems. One important set of such signaling molecules are cytokines. The wide distribution of cytokine receptors throughout the body, including the immune and the nervous system allows direct communication between these two entities. In addition to cytokines the nervous system and immune system also communicate with each other using shared ligands such as neurotransmitters and neuroendocrine hormones, and their respective receptors...

Fibromyalgia syndrome (FM), the most common central sensitivity syndrome (CSS) affecting over 5% of the population, is a disorder of chronic widespread pain accompanied by numerous other symptoms that causes significant functional impairment. The core FM symptom domains can be recalled using the FIBRO mnemonic and include Fatigue and Fog (cognitive dysfunction), Insomnia (difficulties with all aspects of sleep including initiation, maintenance and restorative), Blues (depression and anxiety), Rigidity (stiffness in muscles and joints) and Ow! (widespread pain and tenderness)...

Central sensitivity syndromes (CSS) share features of similar multiple symptoms, virtually unknown mechanisms and lack of effective treatments. The CSS nomenclature was chosen over alternatives because it focused on a putative physiological mechanism of central sensitization common to disorders such as fibromyalgia, irritable bowel syndrome, vulvodynia and temporomandibular disorder. Increasing evidence from multiple biological systems suggests a further development. In this new model central sensitization is part of a ensemble that includes also the symptoms of widespread pain, fatigue, unrefreshing sleep and dyscognition...

Central sensitivity syndromes (CSSs) represent a heterogeneous group of disorders (e.g., fibromyalgia [FM], irritable bowel syndrome [IBS], chronic headache, temporomandibular disorders [TMDs], pelvic pain syndromes) that share many common symptoms, with persistent pain being the most prominent feature. Although the etiology and pathophysiology of CSSs are currently incompletely understood, central sensitization has emerged as one of the significant mechanisms. Given that there are currently no known cures for CSSs, people living with these disorders must learn to cope with and manage their symptoms throughout their lives...

In both primary care and consultative practices, patients presenting with fibromyalgia (FM) often have other medically unexplained somatic symptoms and are ultimately diagnosed as having central sensitization (CS). Central sensitization encompasses many disorders where the central nervous system amplifies sensory input across many organ systems and results in myriad symptoms. A pragmatic approach to evaluate FM and related symptoms, including a focused review of medical records, interviewing techniques, and observations, is offered here, giving valuable tools for identifying and addressing the most relevant symptoms...

In 1964, Miyoshi reported a series of patients with diverse symptoms after receiving treatment with silicone or paraffin fillers. Miyoshi named this condition 'human adjuvant disease'. Since then, the literature has been flooded with case reports and case series of granulomatous and systemic autoimmune disorders related to vaccines, infection or other adjuvants such as silicone and other biomaterials. A new term -autoimmune/inflammatory syndrome induced by adjuvants--has recently been coined for a process that includes several clinical features previously described by Miyoshi plus other clinical and laboratory parameters related to exposure to diverse external stimuli...

BACKGROUND AND OBJECTIVES: Central sensitivity syndrome (CSS) encompasses disorders with overlapping symptoms in a spectrum of structural pathology from persistent somatic nociception (eg, osteoarthritis) to absence of tissue injury such as in fibromyalgia, chronic tension-type headache, and myofascial pain syndrome. Likewise, the spectrum of the neuroplasticity mediators associated with CSS might present a pattern of clinical utility. METHODS: We studied the brain-derived neurotrophic factor (BDNF), tumor necrosis factor-α (TNF-α), and interleukins 6 (IL-6) and IL-10 in female patients with CSS absent of structural pathology (chronic tension-type headache [n=30], myofascial pain syndrome [n=29], fibromyalgia [n=22]); with CSS due to persistent somatic/visceral nociception (osteoarthritis [n=27] and endometriosis [n=32]); and in pain-free controls (n=37)...

Chronic pelvic pain (CPP) is a common condition that has a major impact on the quality of life of both men and women. Male CPP is usually attributable to well-defined urogenital conditions (most frequently infectious/non infectious prostatic diseases) or musculoskeletal or bowel diseases, whereas the features of female CPP are much more complex and are of particular clinical and epidemiological importance. It is a multifactorial syndrome that can be due to diseases of the urogenital, gastrointestinal, or musculoskeletal systems, or to neurological or neuropsychiatric disorders...

Pain is the hallmark symptom of fibromyalgia (FM) and other related syndromes, but quite different from that of other rheumatic diseases, which depends on the degree of damage or inflammation in peripheral tissues. Sufferers are often defined as patients with chronic pain without an underlying mechanistic cause, and these syndromes and their symptoms are most appropriately described as "central pain", "neuropathic pain", "nonnociceptive pain" or "central sensitivity syndromes". The pain is particular, regional or widespread, and mainly relates to the musculoskeletal system; hyperalgesia or allodynia are typical...
