Pinar Nalcacioglu, Golge Acaroglu
Nonspecific orbital inflammation is an idiopathic chronic tumor-like inflammation process that usually affects the orbital tissues of both eyes. Isolated optic nerve involvement by an idiopathic inflammatory process is a rare finding. Here, we report a patient with unilateral sudden onset severe orbital pain and headache with visual loss to no light perception that could only be attributed to perineuritis. Radiological findings enabled making the correct diagnosis. Various relevant diagnoses are also discussed...

Buerger's disease is characterized by recurring progressive inflammation and occlusions in small and medium arteries and veins of the limbs. Its cause is unknown, but it is most common in young men with a history of tobacco use. It is responsible for ischemic ulcers and extreme pain in the hands and feet. In many cases, notably in patients with the most severe presentations, there is no possibility of improving the condition with surgery (limb revascularisation), and therefore, alternative therapies (e.g. sympathectomy) is used...

The inflammatory process plays a central role in the development and progression of numerous pathological situations, such as inflammatory bowel disease (IBD), autoimmune and neurodegenerative diseases, metabolic syndrome, and cardiovascular disorders. IBDs involve inflammation of the gastrointestinal area and mainly comprise Crohn's disease (CD) and ulcerative colitis (UC). Both pathological situations usually involve recurring or bloody diarrhea, pain, fatigue and weight loss. There is at present no pharmacological cure for CD or UC...

Carthamin yellow (CY), which is a flavonoid compound isolated from safflower, has various pharmacological effects including promoting blood circulation to remove blood stasis and alleviating pain. CY is a herb used in Chinese traditional medicines. Intervertebral disc degeneration (IDD) is a common spinal disorder and degeneration of nucleus pulposus (NP) cells and inflammation are significant parts of the pathological cascade. The curative effect of CY on NP cells in association with degeneration and inflammation remains to be elucidated...

BACKGROUND: Necrotizing myositis is a rare but life-threatening soft-tissue infection characterized by rapidly spreading inflammation and subsequent necrosis of the affected tissue. The myositis is often caused by toxin-producing, virulent bacteria such as group A β-hemolytic streptococcus and associated with severe systemic toxicity. It is rapidly fatal unless diagnosed promptly and treated aggressively. However, necrotizing myositis is often initially misdiagnosed as a more benign soft-tissue infection as such fulminant, invasive muscle infections are rare with no more than 30 cases reported over the last century...

OBJECTIVES: Pain catastrophizing is conceptualized as a negative cognitive-affective response to anticipated or actual pain and has been associated with important pain-related outcomes. The objective of this prospective study of established rheumatoid arthritis (RA) patients was to explore how pain catastrophizing was related to patient-reported outcomes (PROs), composite scores and assessments of inflammatory activity. METHODS: RA patients starting bDMARD were examined at baseline and after 1, 2, 3, 6 and 12 months with PROs (joint pain/patient's global VAS, MHAQ, RAID score), clinical and laboratory assessments (tender/swollen joint count, assessor's global VAS, ESR/CRP), ultrasound (US) (grey scale/power Doppler of 36 joints and 4 tendons) and pain catastrophizing...

Oxylipins are a group of fatty acid metabolites generated via oxygenation of polyunsaturated fatty acids and are involved in processes such as inflammation, immunity, pain, vascular tone and coagulation. As a result, oxylipins are implicated in many conditions characterized by these processes including cardiovascular disease and aging. The best characterized oxylipins in relation to cardiovascular disease are derived from the ω-6 fatty acid arachidonic acid. These oxylipins generally increase inflammation, hypertension and platelet aggregation, although not universally...

Cytokines are small secreted proteins released by different types of cells with specific effects on cellular signaling and communication via binding to their receptors on the cell surface. IL-10 is known to be a pleiotropic and potent anti-inflammatory and immunosuppressive cytokine that is produced by both innate and adaptive immunity cells including dendritic cells, macrophages, mast cells, natural killer cells, eosinophils, neutrophils, B cells, CD8(+) T cells, and TH1, TH2, and TH17 and regulatory T cells...

The dietary constituent, resveratrol, was recently identified as a transient receptor potential ankyrin 1 (TRPA1) antagonist, voltage-dependent sodium ion (Na(+) ) channel, and cyclooxygenase-2 (COX-2) inhibitor. The aim of the present study was to investigate whether pretreatment with resveratrol attenuates acute inflammation-induced sensitization of nociceptive processing in rat spinal trigeminal nucleus caudalis (SpVc) and upper cervical (C1) dorsal horn neurons, via c-fos immunoreactivity. Mustard oil (MO), a TRPA1 channel agonist, was injected into the whisker pads of rats to induce inflammation...

The exact pathophysiology of interstitial cystitis/painful bladder syndrome is unknown; however, autoimmunity is a valid theory. We developed an autoimmune chronic cystitis model by administration of the medium dose of immunogenic peptide T2. Sixty female C57BL/6 mice were divided into six groups. The control group was not treated with any reagent. CFA group was injected with CFA + normal saline, homogenate group with bladder homogenate + CFA, low-dose group with low dose of T2 peptide + CFA, medium dose group with the medium dose of T2 peptide + CFA, and high-dose group with the high dose of T2 peptide + CFA...

PURPOSE: To evaluate if herpes zoster virus (HZV) reactivation may be considered in the aetiology of cervical radiculopathy. METHODS: The study group was composed of 110 patients (52 M-58F;mean age ± SD:46.5 ± 6.12; range:40-73) with a clinical diagnosis of cervical radiculopathy. Patients with signs of chronic damage on neurophysiological studies were submitted to an X-ray and to an MRI of the cervical spine in order to clarify the cause of the cervical radiculopathy and were investigated for a possible reactivation of HZV; HZV reactivation was considered as "recent" or "antique" if it occurs within or after 24 months from the onset of symptoms, respectively...

Hydrogen sulfide (H2S), a well-established member of the gasotransmitter family, is involved in a variety of physiological functions, including pro-nociceptive action in the sensory system. Although several reports have shown that H2S activates sensory neurons, the molecular targets of H2S action in trigeminal (TG) nociception, implicated in migraine, remains controversial. In this study, using suction electrode recordings, we investigate the effect of the H2S donor, sodium hydrosulfide (NaHS), on nociceptive firing in rat meningeal TG nerve fibers...

Inflammatory and fibrotic events that drive chronic pancreatitis (CP) are likely orchestrated via signaling of soluble cytokines and chemokines systemically and within the pancreas. However, a comprehensive summary of the expression of such factors during CP has not been reported to date. This information is important given continued interest in targeting cytokines that influence CP pathogenesis. Reported data on the expression change of soluble immunomodulatory factors in human CP patients were identified via a literature search using a single search term...
