P Karlsson, S Haroutounian, M Polydefkis, J R Nyengaard, T S Jensen
Aims The introduction of skin biopsies to examine small nerve fiber morphology together with functional measures such as quantitative sensory testing (QST) has led to an improvement in diagnosing patients with small fiber neuropathy (SFN). Quantification of intraepidermal nerve fiber density (IENFD) is an important measure in SFN. However, the relationship between structure and function is not straightforward and the morphological and functional fiber characteristics are still unclear. This study aimed to combine structural and functional measurements to improve the diagnosis of distal symmetric polyneuropathy and small fiber involvement...

An interaction between cutaneous nerves and mast cells may contribute to pain in complex regional pain syndrome (CRPS). To explore this, we investigated the density of dermal nerve fibres, and the density and proximity of mast cells to nerve fibres, in skin biopsies obtained from the affected and unaffected limbs of 57 patients with CRPS and 28 site-matched healthy controls. The percentage of the dermis stained by the pan-neuronal marker protein gene-product 9.5 was lower in the affected limb of patients than in controls (0...

Pain occurs with optic neuropathies associated with inflammatory central nervous system diseases (MS and NMO), idiopathic intracranial hypertension and spontaneous hypotension, giant cell arteritis, immunomediated systemic diseases, compressive lesions, or infective disorders. Pain can precede the onset of visual loss in acute optic neuritis, it can be irradiated to the orbital region in giant cell arteritis and parasellar compressive optic neuropathies, or it may be located to the back of the eye with posterior scleritis...

Cubital tunnel syndrome (CuTS) is the second most common compressive neuropathy in the upper extremity. There are considerable diagnostic and therapeutic challenges associated with treating patients after a failed primary procedure for CuTS. Distinguishing cases of recurrence versus persistence and identifying concomitant pathology can guide treatment. Conditions that mimic CuTS must be carefully ruled out and coexisting dysfunction of the medial antebrachial cutaneous nerve needs to be addressed. Results of revision procedures are not as reliable as primary procedures for CuTS; however, improvements in pain and paresthesias are noted in approximately 75% of patients...

It is estimated that the total annual financial cost for pain management in the U.S. exceeds 100 billion dollars. However, when indirect costs are included, such as functional disability and reduction in working hours, the cost can reach more than 300 billion dollars. In chronic pain patients, the role of pharmacogenetics is determined by genetic effects on various pain types, as well as the genetic effect on drug safety and efficacy. In this review article, we discuss genetic polymorphisms present in different types of chronic pain, such as fibromyalgia, low back pain, migraine, painful peripheral diabetic neuropathy and trigeminal neuralgia...

Background: Metformin may lead to B12 deficiency and neuropathy. There are no published data on the prevalence of Metformin-related B12 deficiency and neuropathy in the Arabian Gulf. Aims: Determine whether Metformin intake is associated with B12 deficiency and whether B12 deficiency is associated with diabetic peripheral neuropathy (DPN) and painful diabetic neuropathy. Methods: Patients with type 2 diabetes mellitus (T2DM) ( n  = 362) attending outpatient clinics at HMC underwent assessment of B12 levels, the DN4 questionnaire, and vibration perception threshold (VPT)...

Neuropathic pain (NP), defined as pain initiated or caused by a primary lesion or dysfunction in the nervous system, is a debilitating chronic pain condition often resulting from cancer treatment. Among cancer patients, neuropathy during cancer treatment is a predisposing event for NP. To identify genetic variants influencing the development of NP, we conducted a genome-wide association study in 1,043 patients with squamous cell carcinoma of the head and neck, based on 714,494 tagging single-nucleotide polymorphisms (SNPs) (130 cases, 913 controls)...

Type 2 diabetes is one of the leading pathologies that increases the risk of improper wound healing. Obesity has become a major risk factor for this disease that is now considered to be the 4th highest cause of preventable blindness according to the World Health Organization. The cornea is the most densely innervated structure in the human body and senses even the slightest injury. In diabetes, decreased corneal sensitivity secondary to diabetic peripheral neuropathy can lead to increased corneal abrasion, ulceration, and even blindness...

BACKGROUND: Gluten neuropathy (GN) is defined as an otherwise idiopathic peripheral neuropathy in the presence of serological evidence of gluten sensitivity (positive native gliadin antibodies and/or transglutaminase or endomysium antibodies). We aimed to compare the quality of life (QoL) of GN patients with that of control subjects and to investigate the effects of a gluten-free diet (GFD) on the QoL. METHODS: All consecutive patients with GN attending a specialist neuropathy clinic were invited to participate...

A 33-year-old woman with history of HIV presented with 4 months of gradually progressing right hip pain and was found to have avascular necrosis (AVN) of both femoral heads. She had no other risk factors for AVN including sickle cell disease, systemic lupus erythematosus, prolonged steroid used or trauma. She initially failed conservative management and ultimately had bilateral hip core decompressions. After decompression therapy, the left femoral head collapsed and patient underwent a left total hip arthroplasty...

This is a case report on a 77-year-old diabetic patient with peripheral neuropathy and paresthesias in his feet, for which he was treated with pregabalin. During the therapy, his eosinophil level was high (60.3%). Pregabalin was stopped, and after one month his differential eosinophil had dropped dramatically, to 7.3%. Based on the Naranjo Adverse Drug Reaction scale, it is probable that the eosinophilia was induced by pregabalin, as the Naranjo probability score was calculated to be 8. BACKGROUND: Pregabalin, a structural derivative of the inhibitory neurotransmitter gamma amino butyric acid, has antiepileptic, analgesic, and anxiolytic properties; therefore, it is used for painful diabetic neuropathy, postherpetic neuralgia, fibromyalgia, and neuropathic pain associated with spinal-cord injury and as adjunctive therapy in refractory partial seizures...

The mechanisms responsible for painful and insensate diabetic neuropathy are not completely understood. Here, we have investigated sensory neuropathy in the Ins2 +/Akita mouse, a hereditary model of diabetes. Akita mice become diabetic soon after weaning, and we show that this is accompanied by an impaired mechanical and thermal nociception and a significant loss of intraepidermal nerve fibers. Electrophysiological investigations of skin-nerve preparations identified a reduced rate of action potential discharge in Ins2 +/Akita mechanonociceptors compared to wildtype littermates, whereas the function of low threshold A-fibers was essentially intact...

BACKGROUND: Chronic pain is a major public health problem resulting in physical and emotional pain for individuals and families, loss of productivity, and an annual cost of billions of dollars. The lack of objective measures available to aid in diagnosis and evaluation of therapies for chronic pain continues to be a challenge for the clinician. OBJECTIVES: Functional magnetic resonance imaging (fMRI) is an imaging technique that can establish regional areas of interest and examine synchronous neuronal activity in functionally related but anatomically distinct regions of the brain, known as functional connectivity...
