Podiatry is the science dealing with the diagnostics and treatment of the foot and ankle and associated tissues and structures by all appropriate methods and also with the local manifestation of the overall processes in this area. Diabetic foot disease is defined as infection, ulceration or destruction of tissues of the foot associated with neuropathy and/or peripheral artery disease in the lower extremity of people with diabetes according to the latest edition of the International Consensus. Successful treatment and prevention of diabetic foot syndrome depends on a holistic approach, in which it is seen as part of the multiple organ involvement...

Clinical observations suggests that Type II Diabetes patients are more susceptible to skin changes which may be associated with reduced coefficient of friction at the fingertips. Reduced coefficient of friction may explain recent reports of fine motor dysfunction in diabetic patients. Coefficient of friction was evaluated using slip force evaluation in a cross-sectional cohort of diabetic patients and age- and sex-matched healthy controls. Covariates of tactile sensation, disease duration, glycated hemoglobin, and clinical diagnosis of peripheral neuropathy were also assessed...

In older studies, a chronic distal symmetric sensory neuropathy was reported as a relatively common manifestation of late Lyme disease in the United States. However, the original papers describing this entity had notable inconsistencies and certain inexplicable findings, such as reports that this condition developed in patients despite prior antibiotic treatment known to be highly effective for other manifestations of Lyme disease. More recent literature suggests that this entity is seen rarely, if at all. A chronic distal symmetric sensory neuropathy as a manifestation of late Lyme disease in North America should be regarded as controversial and in need of rigorous validation studies before acceptance as a documented clinical entity...

Charcot-Marie-Tooth disease type 2A (CMT2A), the most common axonal form of hereditary sensory motor neuropathy, is caused by mutations of mitofusin-2 (MFN2). Mitofusin-2 is a GTPase required for fusion of mitochondrial outer membranes, repair of damaged mitochondria, efficient mitochondrial energetics, regulation of mitochondrial-endoplasmic reticulum calcium coupling and axonal transport of mitochondria. We knocked T105M MFN2 preceded by a loxP-flanked STOP sequence into the mouse Rosa26 locus to permit cell type-specific expression of this pathogenic allele...

Entrapment neuropathies of the fibular nerve and its branches are often underdiagnosed due to the lack of reliable diagnosis using clinical examination and electrophysiologic evaluation. Most fibular nerve compressions may be classified into 2 broad categories: (a) mechanical causes, which occur at fibrous or fibro-osseous tunnels, and (b) dynamic causes related to nerve injury during specific limb positioning. Foot drop resulting from weakness of the dorsiflexor muscles of the foot is a relatively uncommon presentation and closely related to L5 neuropathy caused by a disc herniation...

Erika Mora, Ellen M Lavoie Smith, Clare Donohoe, Daniel L Hertz
Vincristine is a chemotherapeutic agent that is a component of many combination regimens for a variety of malignancies, including several common pediatric tumors. Vincristine treatment is limited by a progressive sensorimotor peripheral neuropathy. Vincristine-induced peripheral neuropathy (VIPN) is particularly challenging to detect and monitor in pediatric patients, in whom the side effect can diminish long term quality of life. This review summarizes the current state of knowledge regarding VIPN, focusing on its description, assessment, prediction, prevention, and treatment...

Neuropathic pain is triggered by the lesions to peripheral nerves which alter their structure and function. Neuroprotective approaches that limit the pathological changes and improve the behavioral outcome have been well explained in different experimental models of neuropathy but translation of such strategies to clinics has been disappointing. Experimental evidences revealed the role of free radicals, especially peroxynitrite after the nerve injury. They provoke oxidative DNA damage and consequent over-activation of the poly(ADP-ribose) polymerase (PARP) upregulates pro-inflammatory pathways, causing bioenergetic crisis and neuronal death...

Here it is shown that paclitaxel induced neuropathy is associated with the development of spontaneous activity (SA) and hyperexcitability in DRG neurons that is paralleled by increased expression of low-voltage-activated calcium channels (T-type; Cav3.2). The percentage of DRG neurons showing SA and the overall mean rate of SA were significantly higher at day 7 of paclitaxel treatment than in rats receiving vehicle. Cav3.2 expression was increased in L4-6 DRG and spinal cord segments in paclitaxel-treated rats, localized to small calcitonin gene-related peptide expressing and isolectin B4 expressing DRG neurons and to glial fibrillary acidic protein-positive spinal cord cells...
