The Association of Olfactory Impairment with Charcot Neuroarthropathy and Possible Links to Causation.

Background: Charcot neuroarthropathy (CN) is a devastating complication of some diseases affecting the peripheral nervous system. Initial subjective and objective presentation of the disease can be variable. Common among all presentations seems to be uncontrolled inflammation yielding dislocations and/or fractures.

Diagnostic Ultrasound of the Soleal Sling.

The soleal sling may be a site of tibial nerve entrapment. Objective diagnosis of this syndrome is difficult with current nerve conduction study techniques, magnetic resonance imaging, and neurosensory testing. Diagnostic ultrasound is ideally suited to visualize the tibial nerve statically and dynamically as it enters the soleal sling, thus making an objective diagnosis of soleal sling impingement much easier.

Nerve decompression after diabetic foot ulceration may protect against recurrence: a 3-year controlled, prospective analysis.

Background: Nerve entrapment, common in diabetes, is considered an associated phenomenon without large consequence in the development of diabetes complications such as ulceration, infection, amputation, and early mortality. This prospective analysis, with controls, of the ulcer recurrence rate after operative nerve decompression (ND) offers an objective perspective on the possibility of frequent occult nerve entrapment in the diabetic foot complication cascade.

Methods: A multicenter cohort of 42 patients with diabetic sensorimotor polyneuropathy, failed pharmacologic pain control, palpable pulses, and at least one positive Tinel's nerve percussion sign was treated with unilateral multiple lower-leg external neurolyses for the indication of pain.

Bioengineered human dermal tissue grafting of necrobiosis lipoidica diabeticorum ulcerations: a case series.

A retrospective case series of sequential patients with recurrent ulcerations associated with necrobiosis lipoidica diabeticorum (NLD) is presented. Standard wound care required 40 ± 7.21 weeks to attain complete epithelialization.

Low long-term risk of foot ulcer recurrence after nerve decompression in a diabetes neuropathy cohort.

Background: Use of nerve decompression in diabetic sensorimotor polyneuropathy is a controversial treatment characterized as being of unknown scientific effectiveness owing to lack of level I scientific studies.

Methods: Herein, long-term follow-up data have been assembled on 65 diabetic patients with 75 legs having previous neuropathic foot ulcer and subsequent operative decompression of the common peroneal and tibial nerve branches in the anatomical fibro-osseous tunnels.

Results: The cohort's previously reported low recurrence risk of less than 5% annually at a mean of 2.

Endoglucanases: insights into thermostability for biofuel applications.

Obtaining bioethanol from cellulosic biomass involves numerous steps, among which the enzymatic conversion of the polymer to individual sugar units has been a main focus of the biotechnology industry. Among the cellulases that break down the polymeric cellulose are endoglucanases that act synergistically for subsequent hydrolytic reactions. The endoglucanases that have garnered relatively more attention are those that can withstand high temperatures, i.

Thermostability in endoglucanases is fold-specific.

Background: Endoglucanases are usually considered to be synergistically involved in the initial stages of cellulose breakdown-an essential step in the bioprocessing of lignocellulosic plant materials into bioethanol. Despite their economic importance, we currently lack a basic understanding of how some endoglucanases can sustain their ability to function at elevated temperatures required for bioprocessing, while others cannot. In this study, we present a detailed comparative analysis of both thermophilic and mesophilic endoglucanases in order to gain insights into origins of thermostability.

Symmetry of sensory loss in developing diabetic sensory polyneuropathy.

The medical literature presents diabetic sensory polyneuropathy (DSPN) as an axonal length-dependent symmetric pathology producing a stocking-like pattern of anesthesia in the lower extremities. This has been based on anecdotal reports. Objective research has shown that damage may not occur in a purely length-dependent manner.

Characteristics of lower extremity pressure sensation impairment in developing diabetic sensory polyneuropathy.

The medical literature presents diabetic sensory polyneuropathy as a length-dependent process producing a stocking distribution of sensory loss in the lower extremities. If a purely length-dependent etiology for diabetic sensory polyneuropathy were true, then a validated comparison of sensory loss at any equidistant site about the forefoot will reveal findings consistent with the accepted stocking pattern of anesthesia. A single-blinded, age-matched, control/experimental study is made into the frequency of apparent purely length-dependent A-beta fiber pathology in developing diabetic sensory polyneuropathy.

The football: an intuitive dressing for offloading neuropathic plantar forefoot ulcerations.

A reproducible, affordable, efficacious and safe modality for offloading neuropathic plantar foot ulcerations was previously presented in a pilot study. A follow-up retrospective multicentre analysis of the football dressing is now presented. Wound healing rates are compared with published data on the total contact cast (TCC) and instant total contact cast (iTCC).

Surgical decompression in lower-extremity diabetic peripheral neuropathy.

Peripheral neuropathy can be a devastating complication of diabetes mellitus. This article describes surgical decompression as a means of restoring sensation and relieving painful neuropathy symptoms. A prospective study was performed involving patients diagnosed as having type 1 or type 2 diabetes with lower-extremity peripheral neuropathy.
