    This study followed 115 patients with diabetes--who between them had 140 feet with Charcot's arthropathy--over six to 114 months (median: 48). A total of 43 patients (37%) developed ulcers in 53 feet. Their treatment was multifactorial. An offloading regimen was adopted, with the use of crutches and therapeutic sandals with soft, individually moulded insoles, followed by adjusted or bespoke shoes. Recalcitrant ulcers were treated with surgery in 16 patients (37%). Antibiotics were needed by 21 patients (49%). The incidence of ulceration was 17% per year. The median time interval between the acute component of Charcot's arthropathy and ulcer development was 36 months (range: 0-120 months). In seven patients, the ulcer developed during the acute phase. In 12 patients the ulcers were localised to the rockerbottom deformity in the mid-foot region, but in 31 patients other regions were affected. Dynamic footprint analysis was used to help adjust the offloading shoe/insole on the rockerbottom deformity. Such ulcers took twice as long to heal as other ulcers. Surgical treatment comprised: major amputation (two patients), arthrodesis for unstable ankle (three patients), toe amputations (seven patients), resection of the rockerbottom deformity (one patient) and other revisions (three patients). One patient died with an unhealed ulcer. There is a four-fold risk of ulcers in diabetic Charcot deformity compared with the overall risk of foot ulcers in diabetic feet. Healing was achieved in 40 patients (93%). The surgical intervention rate of 37% in ulcer cases in Charcot feet was low compared with the literature.

    The purpose of this study is to develop a non-contrast magnetic resonance imaging (MRI) approach to evaluate skeletal muscle perfusion in the diabetic foot based on the concept of angiosomes of the foot. Five healthy volunteers and five participants with diabetes (HbA1c = 7.2 ± 1.8 %) without a history of peripheral artery disease were examined. The non-contrast perfusion measurements were performed during a toe flexion challenge. Absolute perfusion maps were created and two regions (medial and lateral) on the maps were segmented based on angiosomes. Regional difference in the perfusion of foot muscle was readily visualized in the MRI perfusion angiosomes during the challenge. In the participants with diabetes, the perfusion during toe flexion challenge was significantly lower than in healthy volunteers (P < 0.01). The average perfusion for the medial plantar region of the right foot was lower in subjects with diabetes (38 ± 9 ml/min/100 g) than in healthy subjects (93 ± 33 ml/min/100 g). Non-contrast MRI perfusion angiosome maps demonstrate the feasibility of determining regional perfusion in foot muscles during toe challenge and may facilitate evaluation of muscle perfusion in diabetic feet.

    Diabetic foot ulceration is a major complication for patients with diabetes mellitus. Approximately 15% to 25% of patients with Type I and Type II diabetes eventually develop feet ulcers. If not adequately treated, these ulcers may lead to foot infection, and ultimately to total (or partial) lower e

    To analyze Doppler sonographic findings of diabetic feet by estimating the quantitative blood flow volume and by analyzing waveform on Doppler. Doppler sonography was performed in thirty four patients (10 diabetic patients with foot ulceration, 14 diabetic patients without ulceration and 10 normal patients as the normal control group) to measure the flow volume of the arteries of the lower extremities (posterior and anterior tibial arteries, and distal femoral artery. Analysis of doppler waveforms was also done to evaluate the nature of the changed blood flow volume of diabetic patients, and the waveforms were classified into triphasic, biphasic-1, biphasic-2 and monophasic patterns. Flow volume of arteries in diabetic patients with foot ulceration was increased witha statistical significance when compared to that of diabetes patients without foot ulceration of that of normal control group (P<0.05). Analysis of Doppler waveform revealed that the frequency of biphasic-2 pattern was significantly higher in diabetic patients than in normal control group(p<0.05). Doppler sonography in diabetic feet showed increased flow volume and biphasic Doppler waveform, and these findings suggest neuropathy rather than ischemic changes in diabetic feet.

    Full Text Available Diabetic neuropathy is an important complication of the disease, responsible for ulceration and amputation of the foot. Prevention of these problems is difficult mainly because there is no method to correctly access sensibility on the skin of the foot. The introduction of the Pressure-Specified Sensory Device (PSSD TM in the last decade made possible the measurement of pressure thresholds sensed by the patient, such as touch, both static and in movement, on a continuous scale. This paper is the first in Brazil to report the use of this device to measure cutaneous sensibility in 3 areas of the foot: the hallux pulp, the calcaneus, and the dorsum, which are territories of the tibial and fibular nerves. METHOD: Non-diabetic patients were measured as controls, and 2 groups of diabetic patients - with and without ulcers - were compared. The PSSD TM was used to test the 3 areas described above. The following were evaluated: 1 PS (1-point static, 1 PD (1-point dynamic, 2 PS (2-points static, 2 PD (2-points dynamic. RESULTS: The diabetic group had poorer sensibility compared to controls and diabetics with ulcers had poorer sensibility when compared to diabetics without ulcers. The differences were statistically significant (P A neuropatia diabética é uma complicação importante do Diabetes melitus, responsável por ulcerações e amputações de membros inferiores.

    We investigated whether medial arterial calcification (MAC) impairs O2 supply to the exercising foot in diabetic patients with foot lesions. Transcutaneous O2 tension (tcPO2) was monitored at the dorsum of the foot before and after bicycle exercise in 11 diabetic patients with peripheral ischemic vascular disease (PIVD) with or without concomitant existence of MAC, 10 patients with MAC but without PIVD, 10 diabetic control subjects, and 6 nondiabetic control subjects. The mean preexercise tcPO2 level was comparable in these four groups. However, tcPO2 decreased significantly with exercise in feet with PIVD (mean +/- SE -17.9 +/- 2.7%, P less than 0.01, n = 11), regardless of presence or absence of vascular calcification. On the other hand, the value increased significantly with exercise in feet with MAC but without PIVD (21.2 +/- 3.5%, P less than 0.01, n = 10) and in those of diabetic control subjects (14.9 +/- 3.6%, P less than 0.01), respectively. The tcPO2 remained unchanged in the feet of nondiabetic control subjects (1.7 +/- 1.1%). The results suggest that MAC is not associated with reduced O2 supply to the exercising foot in diabetic patients.

    The foot complications of diabetes are severe, disabling, costly and common in the Northern Territory. An understanding of the pathogenesis, the disease spectrum and treatment efficacy, however, is poor. The patterns of disease are documented in the present study; factors associated with good and poor outcomes are identified; and improved management strategies are proposed. All patients presenting to the High Risk Foot Service at Royal Darwin Hospital between March 1997 and March 2000 were included in the present study, and details regarding the status of their feet, their demographics, their treatment and their outcomes were recorded prospectively. Logistic regression analysis was undertaken to determine associations between factors of interest and outcomes of healing and amputation. One hundred and twenty-six patients were recorded, 41% of whom had neuropathic ulcers and 63% of whom had severe disease at presentation. Two types of diabetic foot pathology were recognized that are not usually classified: acute injury without neuropathy (10%) and deep soft tissue infection alone (9%).Thirty-seven percent and 23% of patients required minor and major amputations, respectively. The total number of hospital bed-days was 5813. Total contact casting was associated with good healing rates in 16 patients. Major amputation was associated with ischaemia, severe disease at presentation and increasing age. Patterns of diabetic foot disease which are not commonly recognized are described in the present study; the severity and cost of the problem are documented; and some factors which lead to poor outcome, such as late presentation, are identified. Attention should be paid, through a multidisciplinary team, to timely referral from primary care, patient education, total contact casts and appropriate revascularization.

    The Ponseti method has been shown to be the most effective treatment for congenital clubfoot. The current challenge is to establish sustainable national clubfoot treatment programs that utilize the Ponseti method and integrate it within a nation's governmental health system. The Brazilian Ponseti Program (Programa Ponseti Brasil) has increased awareness of the utility of the Ponseti method and has trained >500 Brazilian orthopaedic surgeons in it. A group of 18 of those surgeons had been able to reproduce the Ponseti clubfoot treatment, and compiled their initial results through structured spreadsheet. The study compiled 1040 patients for a total of 1621 feet. The average follow-up time was 2.3 years with an average correction time of approximately 3 months. Patients required an average of 6.40 casts to achieve correction. This study demonstrates that good initial correction rates are reproducible after training; from 1040 patients only 1.4% required a posteromedial release. Level IV.

    Diabetic sensorimotor polyneuropathy is one of the greatest risk factors for foot ulceration. The current study investigated the measurement properties of the Pressure-Specified Sensory Device in comparison with traditional threshold screening instruments, in several categories of sensory loss. Knowledge of these values may help to identify diabetics at risk for ulceration more reliably. A partially cross-sectional cohort study was carried out in patients with diabetes. Traditional instruments classified each patient into groups representing severity of diabetic sensorimotor polyneuropathy. Demographic characteristics, laboratory measures, and Pressure-Specified Sensory Device measurements were compared between groups. The Bland-Altman method was used to characterize reliability of the Pressure-Specified Sensory Device, and construct validity was determined by comparison with Semmes-Weinstein monofilaments. One hundred fifty-five diabetic patients were measured. Fifteen patients had a diabetic ulcer in their medical history, seven patients were insensate to the 10-g monofilament and had diminished vibration sense (group 1), 34 patients had diminished vibration sense but no elevated cutaneous threshold (group 2), and 99 patients acted as controls (no elevated cutaneous threshold or diminished vibration sense, group 3). The Pressure-Specified Sensory Device distinguished these groups with one-point static cutaneous thresholds alone. Semmes-Weinstein monofilament and Pressure-Specified Sensory Device measurements were not interchangeable. Spatial discrimination (two-point static and two-point moving discrimination) by the Pressure-Specified Sensory Device was more reliable compared with one-point static discrimination. Semmes-Weinstein monofilament (force in grams and pressure in grams per square millimeter) correlations with Pressure-Specified Sensory Device measurements differed between groups. The Pressure-Specified Sensory Device is able to distinguish between

    PEP (Peer Education Programme) Talk: Diabetes, Healthy Feet and You is a peer-led self-management programme developed to address the problems of growing prevalence of diabetes and its complications, and limited health care dollars. An evaluation of the programme, how it might be situated within a public health perspective and potential bridges for its implementation in communities throughout Canada and worldwide, are presented. The programme consisted of workshops that were conducted by volunteer peer leaders and health care professionals in 12 communities in 10 Canadian provinces; the volunteers were supported through monthly mentoring teleconferences, on-line tips and discussion board conversations. A web portal was developed to be used by the team, volunteers and community participants. Workshop curriculum was developed based on diabetes footcare and self-management best practise guidelines. Community participants answered pre-and post-workshop statements that indicated that learning occurred, as indicated by an increase in the number of statements answered correctly. Participants' feedback about the workshops was positive. In telephone follow-up interviews, 97% of respondents reported having changed their foot self-management behaviours. The portal was commonly used according to website visits, but not as much as expected for registration of community participants. It is recommended that this programme be made widely available and tailored to the specific needs of the communities and that further evaluation be conducted.

    Verrucous skin lesions on the feet in diabetic neuropathy (VSLDN) develop in areas with sensory loss in diabetic patients. Although various types of chronic stimulation, such as pressure or friction, are considered an important factor in the development of such lesions, the precise pathogenesis of VSLDN remains obscure, and there is currently no established treatment for this disease. Here, we present a case of VSLDN on the dorsum of the right foot. However, because lymphedema was also observed at the same site, this lesion could also be diagnosed as elephantiasis nostras verrucosa arising in diabetic neuropathy. The lesion was successfully treated with a combination of elastic stocking and mixed killed bacterial suspension and hydrocortisone ointment, which suggested that VSLDN might have been exacerbated by the pre-existing lymphedema. Because various types of chronic stimulation can trigger VSLDN, treatment plans should be devised on a case-by-case basis. Therefore, it is important to investigate the presence of factors that can induce or exacerbate chronic inflammatory stimulation, such as lymphedema in our case, in each patient with VSLDN. © 2015 Japanese Dermatological Association.

    The aim of this preliminary study was to evaluate the predictive value of esophageal clearance scintigraphy (ECS) in the diagnosis of esophageal autonomic neuropathy in diabetic patients without any esophageal symptoms. A single swallon ECS was performed in 12 diabetic patients and 15 normal volunteers, and esophageal transit time (ETT) and esophageal (Es) T 1/2 values were calculated. ETT and Es 1/2 were found to be significantly prolonged in the diabetic group (p<0.01 and p<0.05, respectively). In this preliminary study, our results strongly suggest that ECS may be an important noninvasive diagnostic tool in the evaluation of diabetic patients with asymptomatic esophageal autonomic neuropathy.

    Foot conditions in patients with diabetes mellitus (DM) are major causes of morbidity and disability. Whole body vibration may promote blood circulation in the lower limbs, hence facilitating perfusion and promoting the supply of nutrients and oxygen to comprised tissues. Transcutaneous oxygen levels (TcPO2)>40mmHg in cases of diabetic foot syndrome are associated with a good prognosis in the resolution of ulcers. The objective of this study was to determine whether whole body vibration favors some parameters of interest related to complications associated with the diabetic foot syndrome. Fifty-four patients with DM were included in a 12-week exercise program based on whole body vibration. Glycemic control was determined on the basis of the patients' levels of glycated hemoglobin (HbA1c); sensitivity and TcPO2 levels of each foot were also recorded. Assessments were performed prior to initiating the whole body vibration program and at the end of it. No significant changes were observed in the patients' HbA1c (P=.442) levels or sensitivity (P=.07). A significant 7mmHg increase (Pdiabetic foot syndrome. Copyright © 2016 Elsevier España, S.L.U.

    Home glucose monitoring with the use of reflectance meters is an important adjunct in the care of pregnant women with insulin-dependent diabetes. The accuracy of reflectance meters for the assay of capillary glucose specimens has been well documented. The present preliminary study was undertaken to determine the utility of outpatient screening for gestational diabetes mellitus with the use of a reflectance meter (Accu-Chek, Boehringer Mannheim Co.). One hundred twenty-five patients in our high-risk practice had a standard 50 gm glucose load at 26 to 28 weeks' gestation. Capillary glucose values were measured on site with the Accu-Chek. Venous plasma glucose levels were measured by the central laboratory chemistry analyzer. While the laboratory (x) and meter (y) glucose determinations between the two sets of values were highly correlated (R = 0.89, p less than 0.001), there was a significant difference in their average values (x = 111.74, y = 136.35, p less than 0.0001). With the use of a receiver operator characteristic curve, a meter value of 160 mg/dl was determined as the optimal threshold for performing a 3-hour glucose tolerance test. The sensitivity and specificity with the use of a meter value of 160 mg/dl were 93% and 96%, respectively, for detecting an abnormal screening test in venous plasma (greater than or equal to 135 mg/dl). A total of 32 glucose tolerance tests were performed, with four patients included who had venous values less than 135 mg/dl. All eight patients with gestational diabetes mellitus were correctly identified. These data suggest that a glucose reflectance meter can be used for accurate outpatient screening of gestational diabetes mellitus. The potential advantages of capillary blood glucose screening include both cost and efficiency. Patients with abnormal screening values can be promptly identified and scheduled for a follow-up 3-hour glucose tolerance test.

    The aim of this article is to investigate the association of limited joint mobility and foot sole hardness in north Asian Indian type 2 diabetic patients. Limited joint mobility and hardness of the foot sole were measured for 39 subjects attending the AIIMS Endocrinology & Metabolism Clinic. The total subject divided into three groups: 13 control subjects (nondiabetic), 13 diabetic patients without neuropathy and 13 diabetic neuropathy patients. Neuropathy status was assessed using 10 gm Semen's Weinstein monofilament. Joint mobility parameters, such as ankle dorsiflexion/plantar flexion and metatarsophalangeal-1 dorsiflexion/plantar flexion, are measured using a goniometer. Foot sole hardness was measured using a durometer or shore meter. We found that diabetic patients with a neuropathic foot had significantly reduced joint mobility and increased foot sole hardness, placing them at risk for subsequent ulceration. Metatarsophalangeal-1 dorsiflexion/plantar flexion of both feet of diabetic patients had significant correlation (at p hardness in both feet of diabetic neuropathy subjects. Also linear regression analysis showed that duration of diabetes was significantly associated with the joint mobility parameters. In this study we conclude that joint mobility had reduced further if neuropathy and increased foot sole hardness coexisted owing to high plantar pressures. Hence, both limited joint mobility and increased foot sole hardness appears to be important determinants of foot sole ulceration in diabetic neuropathic subject.

    Full Text Available Medications in treatment and control of diabetes can be costly for pediatric patients and families. Therefore, individuals may seek complementary and alternative therapies, such as cinnamon, in addition to traditional treatments. The objective of this study was to determine acceptability of using cinnamon in treatment of diabetes in a pediatric population with diabetes. Seventy-six pediatric diabetes patients at a diabetes clinic participated in a one-time telephone interview using an 18-item, validated questionnaire. Descriptive statistics were utilized to determine cinnamon acceptability and preferences. The majority of the subjects were between 16-18 years (43%, n = 33, Caucasian (62%, n = 47, and female (67%, n = 51. More than three-fourths were overweight or at risk of being overweight (80%, n = 60. Seventy-six percent stated that they would be willing to try cinnamon for treatment of their diabetes, whereas 14.5% were undecided and 9.2% unwilling. Most (n = 56, 52.5% were willing to take the cinnamon supplement 1-2 times per day. The greatest concerns expressed by subjects were side effects, interaction with current medications, and physician’s willingness to approve and prescribe. This research suggests that in consultation with health professionals, diabetic youth are willing to try cinnamon supplementation in the treatment of diabetes.

    Biofeedback of heart rate variability (HRV) was applied to patients with diabetic polyneuropathy using a new mobile device allowing regularly scheduled self-measurements without the need of visits to a special autonomic laboratory. Prolonged generation of data over an eight-week period facilitated more precise investigation of cardiac autonomic function and assessment of positive and negative trends of HRV parameters over time. Statistical regression analyses revealed significant trends in 11 of 17 patients, while no significant differences were observed when comparing autonomic screening by short-term HRV and respiratory sinus arrhythmia at baseline and after the 8 weeks training period. Four patients showed positive trends of HRV parameters despite the expected progression of cardiac autonomic dysfunction over time. Patient compliance was above 50% in all but two patients. The results of this preliminary study indicate a good practicality of the handheld device and suggest a potential positive effect on cardiac autonomic neuropathy in patients with type 2 diabetes.

    We present our experience at the American University of Beirut Medical Center with two diabetic patients suffering from large necrotic and infected foot ulcers. Both patients were ambulatory at the time of presentation despite their extensive wounds and were believed to have a useful limb with adequate protective sensation worth saving. Below-knee amputation was prevented in both cases by successful soft-tissue coverage of the ulcers using microvascular composite-tissue transfer a few days after performing a preliminary arteriovenous fistula with a long vein graft loop. The flap vessels were anastomosed end-to-end to the arterial and venous limbs of the divided arteriovenous loop. This reconstructive technique of difficult diabetic wounds of the lower extremity, though in two stages, may be safer than one long procedure in a high-risk patient. It is technically easier than long interpositional vein grafts at the same time as free-flap transfer or microvascular anastomoses with small and diseased vessels. It definitely provides more chance of success as larger vessels are used to supply the flap. It permits distension of the vein graft at normotensive physiologic pressures and allows testing the arterial anastomosis as well as the venous flow before final flap transfer. Above all, it allows extreme freedom in performing tension-free anastomoses away from the infected wound.

  15. Does PGE₁ vasodilator prevent orthopaedic implant-related infection in diabetes? Preliminary results in a mouse model.

    Directory of Open Access Journals (Sweden)

    Arianna B Lovati

    Full Text Available BACKGROUND: Implant-related infections are characterized by bacterial colonization and biofilm formation on the prosthesis. Diabetes represents one of the risk factors that increase the chances of prosthetic infections because of related severe peripheral vascular disease. Vasodilatation can be a therapeutic option to overcome diabetic vascular damages and increase the local blood supply. In this study, the effect of a PGE₁ vasodilator on the incidence of surgical infections in diabetic mice was investigated. METHODOLOGY: A S. aureus implant-related infection was induced in femurs of diabetic mice, then differently treated with a third generation cephalosporin alone or associated with a PGE₁ vasodilator. Variations in mouse body weight were evaluated as index of animal welfare. The femurs were harvested after 28 days and underwent both qualitative and quantitative analysis as micro-CT, histological and microbiological analyses. RESULTS: The analysis performed in this study demonstrated the increased host response to implant-related infection in diabetic mice treated with the combination of a PGE₁ and antibiotic. In this group, restrained signs of infections were identified by micro-CT and histological analysis. On the other hand, the diabetic mice treated with the antibiotic alone showed a severe infection and inability to successfully respond to the standard antimicrobial treatment. CONCLUSIONS: The present study revealed interesting preliminary results in the use of a drug combination of antibiotic and vasodilator to prevent implant-related Staphylococcus aureus infections in a diabetic mouse model.

    of 2.5 hours/week over the course of 6 months. High DSM class attendance was reflected by the largest percentage of time spent in the classroom (48.6%). Self-efficacy, social support, and foot care showed significant improvement (P<.05). There were improvement trends in clinical outcomes that were clinically meaningful but did not reach statistical significance given the small sample size. Because relatively little is known about usability, acceptability, and efficacy of health interventions in VEs, this study constitutes an important, innovative first step in exploring the potential of VEs for facilitating DSM. The preliminary data suggest that VEs provide a feasible and useful platform for patients and educators that affects self-management and related mediators. Flexible access to both synchronous and asynchronous diabetes education, skill building activities, and support from a home computer remove barriers to attending clinic-based meetings. This program has potential for improving DSM in an easily disseminated alternative model.

    This report presents a preliminary study investigating the effects of large-volume liposuction on the parameters that determine type 2 diabetes. The study enrolled 31 patients with a body mass index (BMI) exceeding 30 kg/m(2) over a 1-year period. All the liposuction procedures were performed with the patient under local anesthesia using ketamine/valium sedation. Pre- and postoperative blood pressure, fasting glucose, glycosylated hemoglobin (HbA1C), weight, and BMI were evaluated for 16 of the 30 patients who returned for a follow-up visit 3 to 12 months postoperatively. The average aspirate was 8,455 ml without dermolipectomy and 5,795 ml with dermolipectomy. The data reveal a trend of improvement in blood sugar levels associated with weight loss that helps the patients. The average blood sugar level dropped 18% in our return patients, and the average weight loss was 9.2%. The average drop in BMI was 6.2%, and HbA1C showed a decrease of 2.3%. The patients with the best weight loss had the best reduction in blood sugar level and blood pressure. No transfers to the hospital and no thromboebolism occurred for any of the 31 patients. One dehiscence, two wound infections, and three seromas were reported. The authors hypothesize that large-volume liposuction in their series may have motivated some to diet, which could be explored in a larger series with control groups. Liposuction alone did not improve obesity but helped to motivate some of the patients to lose weight. These patients had the best results.

    2013-01-01

    Full Text Available Background: Burning feet syndrome (BFS has been described anecdotally in the literature for over 200 years. Described subjectively by patients as burning, prickling and unremitting with nocturnal exacerbations, the condition draws parallels with the burning dysaesthesia found in diabetic peripheral neuropathy, and appears to display a similar chronicity. Despite being a common symptom, especially among the elderly, its etiology in non-specific and often marked by a lack of objective clinical signs. Historically, burning feet syndrome has been recorded in situations of poor nutrition, including malnourished African populations in the early 20th century, South American plantation workers in the 1920s and during food shortages in the Spanish Civil War. Perhaps the best described and largest outbreak of burning feet occurred amongst prisoners of war (POWs of the Japanese during the 2nd World War in South East Asia and the Far East. In this review we summarise reports of the condition, in particular amongst Far East POWs (FEPOWs, using both the available literature as well as a unique and previously unknown contemporary study carried out in a POW camp. Materials and Methods: During his stay in the Tandjung Priok POW camp, Nowell Peach recorded 54 cases of burning feet seen over a 4 month period during captivity. This data was concealed from his captors and survived to return home with him. Results: 54 prisoners presented over a 4 month period with a mean age of 28 years and mean duration of symptoms of 12 weeks. Neurological signs were meticulously documented. All were on an inadequate diet, 20 (38% were on less than a full ration. Accompanying tropical infections were common including malaria (73%, dengue (45% and dysentery (41%. Discussions: The Peach survey confirmed the frequency of burning feet amongst FEPOWs and was unusual in that the neurological examination and conditions endured were documented in captivity. A paucity of physical signs was

  3. Preliminary analysis of immune activation in early onset type 2 diabetes

    Full Text Available Introduction. First Nations and other Aboriginal children are disproportionately affected by cardiometabolic diseases, including type 2 diabetes (T2D. In T2D, the disruption of insulin signalling can be driven by pro-inflammatory immunity. Pro-inflammatory responses can be fueled by toll-like receptors (TLR on immune cells such as peripheral blood mononuclear cells (PBMC, a white blood cell population. TLR4 can bind to lipids from bacteria and food sources activating PBMC to produce cytokines tumour necrosis factor (TNF-α and interleukin (IL-1β. These cytokines can interfere with insulin signalling. Here, we seek to understand how TLR4 activation may be involved in early onset T2D. We hypothesized that immune cells from youth with T2D (n=8 would be more reactive upon TLR4 stimulation relative to cells from age and body mass index (BMI-matched controls without T2D (n=8. Methods. Serum samples were assayed for adipokines (adiponectin and leptin, as well as cytokines. Freshly isolated PBMC were examined for immune reactivity upon culture with TLR4 ligands bacterial lipopolysaccharide (LPS, 2 and 0.2 ng/ml and the fatty acid palmitate (200 µM. Culture supernatants were evaluated for the amount of TNF-α and IL-1β produced by PBMC. Results. Youth with T2D displayed lower median serum adiponectin levels compared to controls (395 vs. 904 ng/ml, p<0.05. PBMC isolated from youth with and without T2D produced similar levels of TNF-α and IL-1β after exposure to the higher LPS concentration. However, at the low LPS dose the T2D cohort exhibited enhanced IL-1β synthesis relative to the control cohort. Additionally, exposure to palmitate resulted in greater IL-1β synthesis in PBMCs isolated from youth with T2D versus controls (p<0.05. These differences in cytokine production corresponded to greater monocyte activation in the T2D cohort. Conclusion. These preliminary results suggest that cellular immune responses are exaggerated in T2D, particularly

    No long-term data are available regarding the effects of emollients in treating severe foot skin xerosis in patients with diabetes. We evaluated the efficacy of 8 month urea, arginine and carnosine cream (UC) in comparison with a glycerin-based emollient cream (SEC) in type 2 patients with diabetes who had severe foot xerosis. We assessed the effect of UC and SEC on skin hydration in a randomized, assessor-blinded study in 50 patients treated with UC (N = 25) or SEC (N = 25) for 32 weeks with a twice daily application. Primary outcomes were a 9 point Xerosis Assessment Scale (XAS) score and a 4 point Overall Cutaneous Score (OCS), evaluated at baseline and after 4, 12 and 32 weeks. Skin hydration and desquamation were also objectively evaluated by means of a bio-impedance skin analysis device (Hydr8 * ) at baseline and at week 32. UC induced greater hydration than SEC (p = 0.001) with a 91% reduction at week 32 in XAS score vs. baseline. After 4 weeks, compared with the SEC treated group, the XAS score in the UC treated group was significantly lower. OCS was reduced by 27% from baseline to end of the study in the UC group, and increased by 8% in the SEC group (p = 0.02; between groups). At month 8, skin hydration and desquamation evaluated by the digital skin analysis system statistically improved in UC treated subjects in comparison with baseline and SEC group values. This study was not double-blind. In order to overcome this problem we performed an assessor-blinded evaluation of the primary endpoints and used an objective measurement tool for skin hydration and desquamation assessment. Using a urea, arginine and carnosine cream for 8 months increases skin hydration and improves skin dryness in type 2 diabetic patients in comparison with a glycerol-based emollient cream, with a greater efficacy observed as early as 4 weeks into treatment.

All patients followed in Pediatric Endocrinology and Metabolism Unit of Gaziantep University Faculty of Medicine and also control subjects had no hypertension, obesity, hyperlipidemia, anemia, and infection. Blood samples were collected during routine analysis, after overnight fasting. Serum melatonin levels were analyzed with ELISA. Results: There were no statistically significant differences related with age, sex, BMI distribution between diabetic group and control group. Mean diabetic duration was 2.89 ± 2.69 years. The variables were in the equation. Mean melatonin level in diabetic group was 6.75 ± 3.52 pg/ml and mean melatonin level in control group was 11.51 ± 4.74 pg/ml. Melatonin levels were significantly lower in diabetic group compared to controls (P < 0.01. Conclusions: Melatonin was associated with type 1 diabetes mellitus significantly. Because of the varied roles of melatonin in human metabolic rhythms, these results suggest a role of melatonin in maintaining normal rhythmicity. Melatonin may play role in preventing process of inflammation and oxidative stress.

    A population-based sample of Seventh-Day Adventists was studied to determine the relationship between vegetarian status, body mass index (BMI), obesity, diabetes mellitus (DM), and hypertension, in order to gain a better understanding of factors influencing chronic diseases in Barbados. A systematic sampling from a random start technique was used to select participants for the study. A standard questionnaire was used to collect data on demographic and lifestyle characteristics, to record anthropometrics and blood pressure measurements, and to ascertain the hypertension and diabetes status of participants. The sample population consisted of 407 Barbadian Seventh-Day Adventists (SDAs), who ranged in age from 25 to 74 years. One hundred fifty-three (37.6%) participants were male, and 254 (62.4%) were female, and 43.5% were vegetarians. The prevalence rates of diabetes and hypertension were lower among long-term vegetarians, compared to non-vegetarians, and long-term vegetarians were, on average, leaner than non-vegetarians within the same cohort. A significant association was observed between a vegetarian diet and obesity (vegetarian by definition P=.04, self-reported vegetarian P=.009) in this population. Other components of the study population lifestyle should be further analyzed to determine the roles they may plan in lessening the prevalence rates of obesity, diabetes, and hypertension.

    To determine lipid serum levels, lipoproteins and other markers related to nephropathy and peripheral arterial disease (PAD) in a type 2 diabetes population stratified according to their level of renal dysfunction. A cross-sectional study was conducted on 72 type 2 diabetic patients followed-up in outpatient clinics. Patients were divided into 4 groups according to their estimated glomerular filtration rate (eGFR, mL/min) and albumin/creatinine ratio (ACR, mg/g) (eGFR > 60 and ACR 60 and ACR > 30 [n = 12], eGFR30-60 [n = 23] and eGFR renal and hematology parameters were measured. Finally, a multivariate Wald stepwise logistic regression statistic analysis was performed to determine variables independently associated with the presence of renal dysfunction. The univariate statistical analysis showed that the higher renal dysfunction, the higher the prevalence of hypertension, smoking habit and triglycerides levels, and the lower hemoglobin levels (P renal dysfunction (eGFR < 60 mL/min.). The further inclusion of the presence of PAD in the statistical model did not modify those associations. The results confirm the relationship between triglycerides levels and diabetic nephropathy, independently of the presence of PAD. Copyright © 2013 Sociedad Española de Arteriosclerosis.

    In brief Active people often develop friction blisters on their feet. Although such blisters rarely create significant medical problems, they can be quite painful and can hinder athletic performance. People can decrease the chance of blister formation by wearing properly fitting shoes, doubling up on socks, and applying dressings or lubricants. If lesions do develop, conservative treatment will speed healing and lessen pain and disability.

    A dynamic study study on secretion of HGH in diabetic girls under the combined stimulus of L-dopa and L-arginina is performed. Serum levels for Zinc and copper are measured. Results show that as HGH increase, copper levels decrease. Correlation (r = 0.81, p = 0.05) points to an inverse dependence of both parameters. Concomitantly, the values obtained for zinc and copper are correlated (r = 0.82, p = 0.03). During stimulation, all patients showed an increase in glycemia and a significant correlation between both parameters was found (r = 0.76, p = 0.05).

    Objective:To investigate the influence of stigliptin and metformin treatment on glucose fluctuation and serum inflammatory factors in preliminary diagnosed Type 2 diabetes mellitus. Methods: From January 2014 to December 2015, 168 cases of patients with newly diagnosed Type 2 diabetes mellitus were recruited and divided randomly into observation group and control group. The observation group was given sitgliptin (Januvia, 100 mg per d), while the control group was given metformin (Glucophage tablet, initial dose 0.5 g bid, twice per d), and the dosage of drugs was adjusted every 2 weeks according to glucose level. If the glucose level still wasn’t controlled to reach the normal standard by maximum dosage of drugs, 0.5 g bid of acarbose (Glucobay) was applied for the treatment 3 times one day till the glucose level reached the normal standard and the observation was kept for 6 months. The HbA1c, BMI, fluctuation indexes, and serum inflammatory factors of two groups were compared. Results: After the treatment of control group and observation group, the differences of PPGE (t=8.425,P=0.012), MAGE (t=7.348,P=0.014) and MODD (t=9.327,P=0.010) between two groups were significant (P<0.05). The differences of IL-6 (t=6.337,P=0.010) and TNF-α(t=6.521,P=0.011) level of observation group and control group after treatment were statistical significant (P<0.05).Conclusions:The sitgliptin could not only achieve glycemic control goal as metformin, but also induce glucose fluctuation and inhibit serum inflammation better.

    Full Text Available BACKGROUND: Walking and cardiovascular mortality are inversely associated in type 2 diabetes, but few studies have objectively measured associations of walking with individual cardiovascular risk factors. Such information would be useful for "dosing" daily steps in clinical practice. This study aimed to quantify decrements in blood pressure and glycated hemoglobin (A1C per 1,000 daily step increments. METHODOLOGY/PRINCIPAL FINDINGS: Two hundred and one subjects with type 2 diabetes underwent assessments of step counts (pedometer-measured, blood pressure, A1C and anthropometric parameters. Due to missing data, the final analysis was conducted on 83 women and 102 men, with a mean age of 60 years. Associations of daily steps with blood pressure and A1C were evaluated using sex-specific multivariate linear regression models (adjusted for age, ethnicity, and BMI. Potential sex differences were confirmed in a combined model (women and men with interaction terms. Mean values for daily steps, blood pressure, A1C and BMI were 5,357 steps/day; 137/80 mm Hg; 7.7% and 30.4 kg/m(2 respectively. A 1,000 daily step increment among women was associated with a -2.6 (95% CI: -4.1 to -1.1 mm Hg change in systolic and a -1.4 (95% CI: -2.2 to -0.6 mm Hg change in diastolic blood pressure. Among men, corresponding changes were -0.7 (95% CI: -2.1 to 0.7 and -0.6 (95% CI: -1.4 to 0.3 mm Hg, respectively. Sex differences were confirmed in combined models. Step counts and A1C did not demonstrate clinically important associations. CONCLUSIONS/SIGNIFICANCE: A 1,000 steps/day increment is associated with important blood pressure decrements among women with type 2 diabetes but the data were inconclusive among men. Targeted "dose increments" of 1,000 steps/day in women may lead to measurable blood pressure reductions. This information may be of potential use in the titration or "dosing" of daily steps. No associations were found between step count increments and A1C.

    To review the imaging findings, age and gender distribution of chondroblastoma of the hands and feet. Twenty-five cases of pathologically proven chondroblastoma of the hands and feet were reviewed. Available imaging modalities included radiographs (n=24), CT (n=3), MRI (n=5), and radionuclide bone scintigraphy (n=1). The following imaging features for each case were tabulated: location, presence of sclerotic margin, calcification, expansion, presence of fluid/fluid levels on cross-sectional imaging and surrounding edema on MRI. The images were evaluated for skeletal maturity using closure of the physeal plate in the region as a standard. The average age at time of diagnosis was 23 years (range 7-57 years). Eighty-four percent (n=21) of the patients were skeletally mature. Males (20 of 25) outnumbered females by a ratio of 5:1. The bones of the foot accounted for 22 cases: calcaneus (n=8), talus (n=8), metatarsals (n=3), and the cuboid (n=3). The bones of the hand accounted for three cases: phalanx (n=1), triquetrum (n=1), and a metacarpal (n=1). Radiographically all lesions were osteolytic with identifiable calcification in 54% (13 of 24). Fluid/fluid levels were seen in four of five cases on MRI. Edema on MR images was seen in 40% (2 of 5). The size of the lesions ranged from 2 to 41 cm{sup 2}. Chondroblastomas of the hands and feet share many of the radiographic characteristics seen in the long bones, but manifest in skeletally mature patients with a higher male to female ratio than in long bone chondroblastoma. Talar and calcaneal lesions were encountered only in males. Chondroblastoma of the wrist and hand appears to be exceptionally rare. (orig.)

    Full Text Available Abstract Background Aldosterone levels are elevated in a rat model of type 2 diabetes mellitus, the Zucker Diabetic fatty rat (ZDF. Moreover blood pressure in ZDF rats is salt-sensitive. The aim of this study was to examine the effect of the aldosterone antagonist eplerenone on structural and mechanical properties of resistance arteries of ZDF-rats on normal and high-salt diet. Methods After the development of diabetes, ZDF animals were fed either a normal salt diet (0.28% or a high-salt diet (5.5% starting at an age of 15 weeks. ZDF rats on high-salt diet were randomly assigned to eplerenone (100 mg/kg per day, in food (ZDF+S+E, hydralazine (25 mg/kg per day (ZDF+S+H, or no treatment (ZDF+S. Rats on normal salt-diet were assigned to eplerenone (ZDF+E or no treatment (ZDF. Normoglycemic Zucker lean rats were also divided into two groups receiving normal (ZL or high-salt diet (ZL+S serving as controls. Systolic blood pressure was measured by tail cuff method. The experiment was terminated at an age of 25 weeks. Mesenteric resistance arteries were studied on a pressurized myograph. Specifically, vascular hypertrophy (media-to-lumen ratio and vascular stiffness (strain and stress were analyzed. After pressurized fixation histological analysis of collagen and elastin content was performed. Results Blood pressure was significantly higher in salt-loaded ZDF compared to ZDF. Eplerenone and hydralazine prevented this rise similarily, however, significance niveau was missed. Media-to-lumen ratio of mesenteric resistance arteries was significantly increased in ZDF+S when compared to ZDF and ZL. Both, eplerenone and hydralazine prevented salt-induced vascular hypertrophy. The strain curve of arteries of salt-loaded ZDF rats was significantly lower when compared to ZL and when compared to ZDF+S+E, but was not different compared to ZDF+S+H. Eplerenone, but not hydralazine shifted the strain-stress curve to the right indicating a vascular wall composition

    Full Text Available Type 1 diabetes mellitus is characterized by the destruction of pancreatic islet beta cells, which leads to insulin insufficiency, hyperglycemia, and reduced metabolic glucose level. Insulin replacement is the current standard therapy for type 1 diabetes mellitus but has several limitations. Pancreatic islet transplantation can result in the production of exogenous insulin, but its use is limited by immune-rejection and donor availability. Recent studies have shown that mesenchymal stem cells (MSCs can transdifferentiate into insulin-producing cells (IPCs, which could be utilized for diabetes mellitus treatment. Previously published reports have demonstrated that MSC or IPC transplantation could produce significant improvement in mouse models of diabetes mellitus. This study was aimed at determining the effects of two different methods of MSC transplantation on the efficacy of diabetes mellitus treatment in mouse models. The MSCs were isolated from umbilical cord blood and were proliferated following a previously published procedure. Diabetes mellitus was induced in mice by streptozotocin (STZ injection. Thirty days after transplantation, the weight of the mice treated by intra-venous infusion and intra-pancreatic injection was found to be 22% and 14% higher than that of the un-treated mice. The blood glucose concentrations in both intra-venous infusion and intra-pancreatic injection groups decreased and remained more stable than those in the control group. Moreover, insulin was detected in the serum of the treated mice, and the pancreas also showed gradual recovery. Based on the results of this preliminary investigation, intra-venous infusion seems more suitable than intra-pancreatic injection for MSC transplantation for diabetes mellitus treatment.

    Full Text Available Abstract Background The successful Greater Green Triangle Diabetes Prevention Program (GGT DPP, a small implementation trial, has been scaled-up to the Victorian state-wide ‘Life!’ programme with over 10,000 individuals enrolled. The Melbourne Diabetes Prevention Study (MDPS is an evaluation of the translation from the GGT DPP to the Life! programme. We report results from the preliminary phase (pMDPS of this evaluation. Methods The pMDPS is a randomised controlled trial with 92 individuals aged 50 to 75 at high risk of developing type 2 diabetes randomised to Life! or usual care. Intervention consisted of six structured 90-minute group sessions: five fortnightly sessions and the final session at 8 months. Participants underwent anthropometric and laboratory tests at baseline and 12 months, and provided self-reported psychosocial, dietary, and physical activity measures. Intervention group participants additionally underwent these tests at 3 months. Paired t tests were used to analyse within-group changes over time. Chi-square tests were used to analyse differences between groups in goals met at 12 months. Differences between groups for changes over time were tested with generalised estimating equations and analysis of covariance. Results Intervention participants significantly improved at 12 months in mean body mass index (−0.98 kg/m2, standard error (SE = 0.26, weight (−2.65 kg, SE = 0.72, waist circumference (−7.45 cm, SE = 1.15, and systolic blood pressure (−3.18 mmHg, SE = 1.26, increased high-density lipoprotein-cholesterol (0.07 mmol/l, SE = 0.03, reduced energy from total (−2.00%, SE = 0.78 and saturated fat (−1.54%, SE = 0.41, and increased fibre intake (1.98 g/1,000 kcal energy, SE = 0.47.

    Pancreatologists have often divided research of the pancreas based upon the origin of the function or disease, namely the endocrine or exocrine pancreas. In fact, as a result, many of our meetings and conferences have followed separate paths. Interestingly, among patients with chronic pancreatitis and pancreatic cancer, both disorders of the exocrine pancreas, diabetes is common. However, the clinical features of the diabetes associated with these two differ. Peripheral insulin resistance and hyperinsulinemia are the predominant diabetic traits in pancreatic cancer, while reduced islet cell mass and impaired insulin secretion are observed more often in chronic pancreatitis. The causal relationship between diabetes and pancreatic cancer remains an intriguing but unanswered question. Since diabetes often precedes pancreatic cancer, it is regarded as a potential risk factor for malignancy. On the other hand, there remains the possibility that pancreatic cancer secretes diabetogenic factors. Regardless of how the science ultimately illuminates this issue, there is increasing interest in utilizing screening for diabetes to aid early detection of pancreatic tumor lesions. Therefore, in this issue of Pancreatology and the Web, we explore the topic of diabetes to keep us alert to this very important association, even if we study diseases of the exocrine pancreas.

    The paper summarizes the research on cold protection of feet. There exist several conflicting requirements for the choice of the best suited footwear for cold exposure. These conflicts are related to various environmental factors, protection needs and user comfort issues. In order to reduce such conflicts and simplify the choice of proper footwear the paper suggests dividing the cold into specific ranges that are related to properties and state of water and its possibility to penetrate into, evaporate from or condensate in footwear. The thermo-physiological background and reactions in foot are briefly explained, and main problems and risks related to cold injuries, mechanical injuries and slipping discussed. Footwear thermal insulation is the most important factor for protection against cold. The issues related to measuring the insulation and the practical use of measured values are described, but also the effect of socks, and footwear size. Other means for reducing heat losses, such as PCM and electrical heating are touched. The most important variable that affects footwear thermal insulation and foot comfort is moisture in footwear. In combination with motion they may reduce insulation and thus protection against cold by 45%. The paper includes recommendations for better foot comfort in cold.

    The cause of death for raptors poisoned at illegal carbofuran-Iaced predator baits is often not confirmed because the carcass matrices that are conventionally analyzed are not available due to decomposition and scavenging. However, many such carcasses retain intact feet that may have come into contact with carbofuran. Eastern screech owls (Otus asio) were exposed to carbofuran via simulated predator baits. Detection of carbofuran from owl feet weathered for 28 days demonstrated the temporal reliability of using feet during a forensic investigation. Raptor carcasses previously not submitted for residue analysis because of a lack of the conventional matrices may now be salvaged for their feet.

    My career award was for imaging the upper mantle beneath North America. The research proposed was timely because of Earthscope and novel because of the proposed simultaneous inversion of different types of seismic data as well as the inclusion of mineral physics data on the effects of volatiles on seismic properties of the mantle. This research has been challenging and fun and is still on-going. The educational component of my career award consists of feet-on and eyes-open learning of seismology through an educational kiosk and field trips to actual seismic stations. The kiosk and field station have both been growing over the years, as has the audience. I started with the field station in-doors, so it doubled as the kiosk along with a palmtop terminal. Groups of minority elementary school children would look at the mysterious hardware of the "field" station and then jump up and down so they could awe at the peaks in the graph on the palmtop screen that they created. This has evolved into a three-screen kiosk, of which one screen is a touch screen along with a demonstration seismometer. The field station is now in a goat shed near the epicenter of an actual 2010 earthquake inIllinois, which is soon to be replaced by a TA station of Earthscope. The audience has grown to entire grades of middle-school children and activities have evolved from jumping to team-experimentation and the derivation of amplitude-distance relationships following a collaborative curriculum. Addressing the questions in the session description: 1) Education is more fun and effective when one can work in a team with an enthusiastic educator. 2) My education activities are strongly related to my field of expertise but very loosely related to the research carried out with the career award. It appears that not the research outcomes are of interest to students, but instead the simplification and accessibility of the process of research that is of interest. 3) The education component of the career

    Full Text Available Abstract Backgorund Mixed hyperlipidemia is common in patients with diabetes. Statins, the choice drugs, are effective at reducing lipoproteins that contain apolipoprotein B100, but they fail to exert good control over intestinal lipoproteins, which have an atherogenic potential. We describe the effect of prescription omega 3 fatty acids on the intestinal lipoproteins in patients with type 2 diabetes who were already receiving fluvastatin 80 mg per day. Methods Patients with type 2 diabetes and mixed hyperlipidemia were recruited. Fasting lipid profile was taken when patients were treated with diet, diet plus 80 mg of fluvastatin and diet plus fluvastatin 80 mg and 4 g of prescription omega 3 fatty acids. The intestinal lipoproteins were quantified by the fasting concentration of apolipoprotein B48 using a commercial ELISA. Results The addition of 4 g of prescription omega 3 was followed by significant reductions in the levels of triglycerides, VLDL triglycerides and the triglyceride/HDL cholesterol ratio, and an increase in HDL cholesterol (P Conclusion Our preliminary findings therefore suggest an additional benefit on postprandial atherogenic particles when omega 3 fatty acids are added to standard treatment with fluvastatin.

    Diabetes is considered a group of diseases with chronic hyperglycemia caused by various organ disorders, failure or damage as a common feature. Hyperglycemia exerts toxic effect on endothelium, promotes oxidative stress, inhibits bioavailability of nitrogen monoxide (NO) and leads to formation of advanced glycation end products. Moreover, hyperglycemia induces production of reactive oxygen specimens (ROS) through several distinct mechanisms, such as: glucose autoxydation activation of polyol (sorbitol-aldose reductase) pathway, non-enzymatic glycation and neutrophil granulocyte's stimulation. These changes lead to uncontrolled oxidation and peroxidation of lipids, nucleic acids, certain enzymes and most of all--oxidative protein damage (OPD) in many tissues. The aim of this study was to evaluate influence of exposure to tobacco smoke on lipid peroxidation and liver function in experimentally induced diabetes. The research showed that the protein level in blood serum did not change neither in case of induced diabetes nor after tobacco smoke exposure. However a statistically significant increase of lipid peroxidation was observed in rats with pharmacologically induced diabetes. In animals exposed to tobacco smoke only lipid peroxidation increasing trend was demonstrated, while in animals with induced diabetes and exposed to tobacco smoke a statistically significant decrease of lipid peroxidation was noticed. In the adopted experimental model basically no alterations of hepatic aminotranspherases were observed, with exception of AIAT in the group of diabetic animals compared to rats in the control group. Results of the study do not explicitly explain the influence of tobacco smoking in experimentally induced diabetes on lipid peroxidation and liver functions.

    Background: Plantar pressure serves as a key factor for predicting ulceration in the feet of diabetes patients.We designed this study to analyze plantar pressure changes and correlating risk factors in Chinese patients with type 2 diabetes.Methods: We recruited 65 patients with type 2 diabetes.They were invited to participate in the second wave 2 years later.The patients completed identical examinations at the baseline point and 2 years later.We obtained maximum force, maximum pressure, impulse, pressure-time integral, and loading rate values from 10 foot regions.We collected data on six history-based variables, six anthropometric variables, and four metabolic variables of the patients.Results: Over the course of the study, significant plantar pressure increases in some forefoot portions were identified (P < 0.05), especially in the second to forth metatarsal heads.Decreases in heel impulse and pressure-time integral levels were also found (P < 0.05).Plantar pressure parameters increased with body mass index (BMI) levels.Hemoglobin A1 c (HbA1 c) changes were positively correlated with maximum force (β =0.364, P =0.001) and maximum pressure (β =0.366, P =0.002) changes in the first metatarsal head.Cholesterol changes were positively correlated with impulse changes in the lateral portion of the heel (β =0.179, P =0.072) and pressure-time integral changes in the second metatarsal head (β =0.236, P =0.020).Ankle-brachial index (ABI) changes were positively correlated with maximum force changes in the first metatarsal head (β =0.137, P =0.048).Neuropathy symptom score (NSS) and common peroneal nerve sensory nerve conduction velocity (SCV) changes were positively correlated with some plantar pressure changes.In addition, plantar pressure changes had a correlation with the appearance of infections, blisters (β =0.244, P =0.014), and calluses over the course of the study.Conclusions: We should pay attention to the BMI, HbA1c, cholesterol, ABI, SCV, and NSS

  13. Effect of Oral Alpha Lipoic Acid in Preventing the Genesis of Canine Diabetic Cataract: A Preliminary Study

    Directory of Open Access Journals (Sweden)

    David L. Williams

    2017-03-01

    Full Text Available Blinding cataract is a significant effect of canine diabetes with 75% of animals affected two years after diagnosis. Lens opacification occurs primarily through the generation of sorbitol, a sugar alcohol, through the action of aldose reductase (AR. The osmotic effect of sorbitol draws water into the lens, causing opacification. Inhibition of AR should thus prevent the generation of cataracts. A topical AR inhibitor has been shown to have this effect, as has the commercially available neutraceutical OcuGLO, containing the AR inhibitor alpha lipoic acid (ALA together with other plant-based antioxidants. Here a comparison is made between the number of diabetic dogs developing cataracts when given oral ALA alone and those given a mix containing ascorbic acid and tocopherol. Animals given ALA developed significantly fewer lens opacities than those given conventional antioxidants. Cataracts which formed occurred at a significantly greater duration after the commencement of treatment than those on the antioxidant mix. Although this is a small study conducted over a short period, the significant benefit of ALA in diabetic dogs is a reason to evaluate these effects in larger trials. As AR is involved in diabetic retinopathy and neuropathy, this enzyme inhibitor may be worthy of evaluation in preventing these conditions in human diabetics also.

    Full Text Available Chicken feet are products with great commercial importance for the eastern markets. Although Brazil is a large exporter of these products to those markets, little information is available on the sanitary quality of these products. The objective of this study was to evaluate the microbiological quality of frozen chicken feet for human consumption. This study was developed in a slaughterhouse under Federal Inspection, located in the state of Rio Grande do Sul. A total of 98 samples of frozen chicken feet were analyzed, between January and December 2011, for the detection of Salmonella spp., total count of mesophilic bacteria, total coliforms, fecal coliforms, Escherichia coli, Staphylococcus coagulase positive and Clostridium perfringens. About 99% of the results were within the microbiological standards established by the Chinese (world´s largest importer and Brazilian legislation for raw chicken meat. Thus, we conclude that the samples of frozen chicken feet showed satisfactory microbiological quality and no risk to consumer health.

    Cardiovascular mortality is associated with vascular calcification (VC) in hemodialysis (HD) patients. The present study was designed to find factors related with medial artery calcification on the plain radiography of feet by comparing C-reactive protein (CRP), plasminogen activator inhibitor type 1 (PAI-1) and lipid profile including oxidized low density lipoprotein (ox-LDL) and to elucidate associations among these factors in HD patients. Forty-eight HD patients were recruited for this study. VC in the feet was detected in 18 patients (37.5%) among total patients and 12 patients (85.7%) among diabetic patients. Diabetes, cardiovascular disease (CVD), pulse pressure, ox-LDL/LDL were higher and high density lipoprotein (HDL) was lower in patients with VC than in patients without VC. Negative associations were found between HDL and CRP, PAI-1. PAI-1 had positive association with ox-LDL/LDL. History of CVD was the only determinant of vascular calcification on the plain radiography of feet. Ox-LDL/LDL, HDL, CRP, and PAI-1 were closely related with one another in HD patients. History of CVD is the most important factor associated with the presence of VC and low HDL and relatively high oxidized LDL/LDL ratio may affect VC formation on the plain radiography in the feet of HD patients.

    Fibromatosis is benign fibrous tissue condition intermediate between benign fibroma and metastasizing fibrosarcoma. The lesion tends to infiltrate and recur when removed, but do not metastasize. The lesion may be single or multiple, and the likelihood of recurrence after surgical removal varies with location of the lesion and age. A 40-year-old female presented with multiple raised lesions over both feet since 4 years, they were multiple well-defined firm nodules coalescing to form lobulated plaques distributed in a symmetrical pattern over the dorsum of both feet. Histopathology of skin showed epidermis with hyperkeratosis, acanthosis, mild parakeratosis, and prominent granular layer. Superficial dermis was unremarkable and deep dermis showed thick bundles of irregular collagen and fibroblastic proliferation, suggestive of fibromatosis. This case is being reported for its unusual presentation of fibromatosis over the dorsum of both feet. PMID:25821730

    Background Xerosis is a common skin disorder frequently observed in diabetic patients. An effective hydration of foot skin in diabetics is a relevant preventive strategy in order to maintain a healthy foot. Urea is considered an effective hydrating and emollient topical product. The aim of the present study was to evaluate the efficacy of topical urea 5% with arginine and carnosine (Ureadin Rx Db, ISDIN Spain) (UC) in comparison with glycerol-based emollient topical product (Dexeryl, Pierre Fabre) (EC), in Type 2 diabetic patients. Methods We assessed the effect of UC on skin hydration in a randomized, evaluator-blinded comparative study in 40 type II diabetic patients, aged 40–75 years, treated with UC or the comparator for 28 days with a twice-daily application. The principal outcomes were the Dryness Area Severity Index (DASI) Score and the Visual Analogue Score (VAS) for skin dryness evaluated at baseline and at the end of study period by an investigator unaware of treatment allocation. Results UC induced significantly greater hydration than EC with an 89% reduction in DASI score (from 1.6 to 0.2; p emollient product. (Dutch Trials Register trial number 3328). PMID:23009311

    Full Text Available In the past decades, researchers have deeply studied pathological and nonpathological gait to understand the human ankle function during walking. These efforts resulted in the development of new lower limb prosthetic devices aiming at raising the 3C-level (control, comfort, and cosmetics of amputees. Thanks to the technological advances in engineering and mechatronics, challenges in the field of prosthetics have become an important source of interest for roboticists. Currently, most of the bionic feet are still on a research level but show promising results and a preview of tomorrow's commercial prosthetic devices. In this paper, the authors present the current state-of-the-art and the latest advances in propulsive bionic feet with its actuation principles. The context of this review study is outlined followed by a brief description of the basics in human biomechanics and criteria for new prosthetic designs. A new categorization based on the actuation principle of propulsive ankle-foot prostheses is proposed. Based on simulations, the general principles and benefits of each actuation method are explained. The corresponding latest advances in propulsive bionic feet are presented together with their main characteristics and scientific outcomes. The authors also propose to the reader a comparison analysis of the presented devices with a discussion of the general tendencies in new prosthetic feet.

    To estimate the prevalence of flexible flat feet in the provincial population of 4- to 13-year-old schoolchildren and the incidence of treatments considered unnecessary. Province of Málaga, Spain. We examined and graded by severity a sample of 1181 pupils taken from a total population of 198 858 primary schoolchildren (CI: 95%; margin of error: 5%). The sample group was separated into three 2-year age groups: 4 and 5 years, 8 and 9 years, and 12 and 13 years. The plantar footprint was classified according to Denis1 into three grades of flat feet: grade 1 in which support of the lateral edge of the foot is half that of the metatarsal support; grade 2 in which the support of the central zone and forefoot are equal; and grade 3 in which the support in the central zone of the foot is greater than the width of the metatarsal support. The statistical analysis for the evaluation of the differences between the groups was performed with Student's t and chi2 tests as appropriate. The prevalence of flat feet was 2.7%. Of the 1181 children sampled, 168 children (14.2%) were receiving orthopedic treatment, but only 2.7% had diagnostic criteria of flat feet. When we inspected the sample, we found that a number of children were being treated for flat feet with boots and arch supports. Most of them did not have a flat plantar footprint according to the criteria that we used for this work. Furthermore, in the group of children that we diagnosed as having flat feet, only 28.1% were being treated. We found no significant differences between the number of children receiving orthopedic treatments and the presence or absence of a flat plantar footprint. Children who were overweight in the 4- and 5-year-old group showed an increased prevalence for flat feet as diagnosed by us. The data suggest that an excessive number of orthopedic treatments had been prescribed in the province. When extrapolated to the 1997 population of schoolchildren within the age groups studied the figures

    A 45-year-old Afro-Caribbean woman attended the emergency department with worsening dysphagia, abdominal distension, abdominal pain, shortness of breath and generalised weakness. She enjoyed preparing and eating cows-feet stew and preferred to cook the meat with the hair and skin intact. On admission she had a severe microcytic anaemia and was malnourished. Abdominal x-ray and CT revealed a large gastric bezoar. At gastrotomy a foul-smelling 2.42 kg mass of hair, leathery skin and altered food were evacuated from the lesser curvature of the stomach. She had undergone the same procedure 8 years earlier to remove a similar trichobezoar. Following psychiatric review it was deemed that the patient had no underlying psychiatric condition and had full insight into why her trichobezoar had re-occurred. She made a good postoperative recovery and stopped eating cows-feet stew.

To date, this association has been investigated in single-stage ultraendurance races, but not in multistage ultraendurance races. In this case study, we investigated a potential association between fluid intake and feet swelling in a multistage ultraendurance race such as a Deca Iron ultratriathlon with ten Ironman triathlons within 10 consecutive days. A 49-year-old well-experienced ultratriathlete competed in autumn 2013 in the Deca Iron ultratriathlon held in Lonata del Garda, Italy, and finished the race as winner within 129:33 hours:minutes. Changes in body mass (including body fat and lean body mass, foot volume, total body water, and laboratory measurements were assessed. Food and fluid intake during rest and competing were recorded, and energy and fluid turnovers were estimated. During the ten stages, the volume of the feet increased, percentage body fat decreased, creatinine and urea levels increased, hematocrit and hemoglobin values decreased, and plasma [Na+] remained unchanged. The increase in foot volume was significantly and positively related to fluid intake during the stages. The poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. This case report shows that the volume of the foot increased during the ten stages, and the increase in volume was significantly and positively related to fluid intake during the stages. Furthermore, the poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. The continuous feet swelling during the race was

    Collagen constituting the extracellular matrix has been widely used as biocompatible material for human use. In this study, we have selected duck's feet for extracting collagen. A simple method not utilizing harsh chemical had been employed to extract collagen from duck's feet. We fabricated duck's feet collagen/silk hybrid scaffold for the purpose of modifying the degradation rate of duck's feet collagen. This study suggests that extracted collagen from duck's feet is biocompatible and resembles collagen extracted from porcine which is commercially used. Duck's feet collagen is also economically feasible and it could therefore be a good candidate as a tissue engineering material. Further, addition of silk to fabricate a duck's feet collagen/silk hybrid scaffold could enhance the biostability of duck's feet collagen scaffold. Duck's feet collagen/silk scaffold increased the cell viability compared to silk alone. Animal studies also showed that duck's feet collagen/silk scaffold was more biocompatible than silk alone and more biostable than duck's feet or porcine collagen alone. Additionally, the results revealed that duck's feet collagen/silk hybrid scaffold had high porosity, cell infiltration and proliferation. We suggest that duck's feet collagen/silk hybrid scaffold could be used as a dermal substitution for full thickness skin defects.

    In insects, cleaning (grooming) of tarsal attachment devices is essential for maintaining their adhesive ability, necessary for walking on a complex terrain of plant surfaces. How insects obtain information on the degree of contamination of their feet has remained, until recently, unclear. We carried out friction force measurements on walking beetles Gastrophysa viridula (Coleoptera, Chrysomelidae) and counted grooming occurrence on stiff polymer substrata with different degrees of nanoroughness (root mean square: 28-288 nm). Since nanoscopically, rough surfaces strongly reduced friction and adhesion without contaminating feet, we were able to demonstrate, for the first time to our knowledge, that friction force between tarsal attachment pads and the substrate provides an insect with information on the degree of contamination of its attachment structures. We have shown that foot grooming occurrence correlates not only with the degree of contamination but also with the decrease of friction force. This result indicates that insects obtain information about the degree of contamination, not statically but rather dynamically and, presumably, use mechanoreceptors monitoring either tensile/compressive forces in the cuticle or tensile forces between leg segments.

    A proposed apparatus would apply controlled cyclic forces to both feet for the purpose of preventing the loss of bone density in a human subject whose bones are not subjected daily to the mechanical loads of normal activity in normal Earth gravitation. The apparatus was conceived for use by astronauts on long missions in outer space; it could also be used by bedridden patients on Earth, including patients too weak to generate the necessary forces by their own efforts. The apparatus (see figure) would be a modified version of a bicycle-like exercise machine, called the cycle ergometer with vibration isolation system (CEVIS), now aboard the International Space Station. Attached to each CEVIS pedal would be a computer-controlled stress/ vibration exciter connected to the heel portion of a special-purpose pedal. The user would wear custom shoes that would amount to standard bicycle shoes equipped with cleats for secure attachment of the balls of the feet to the special- purpose pedals. If possible, prior to use of the apparatus, the human subject would wear a portable network of recording accelerometers, while walking, jogging, and running. The information thus gathered would be fed to the computer, wherein it would be used to make the exciters apply forces and vibrations closely approximating the forces and vibrations experienced by that individual during normal exercise. It is anticipated that like the forces applied to bones during natural exercise, these artificial forces would stimulate the production of osteoblasts (bone-forming cells), as needed to prevent or retard loss of bone mass. In addition to helping to prevent deterioration of bones, the apparatus could be used in treating a person already suffering from osteoporosis. For this purpose, the magnitude of the applied forces could be reduced, if necessary, to a level at which weak hip and leg bones would still be stimulated to produce osteoblasts without exposing them to the full stresses of walking and

    Full Text Available In this paper, we aim to realize compliant biped walking on uneven terrain with point feet. A control system is designed for a 5-link planar biped walker. According to the role that each leg plays, the control system is decomposed into two parts: the swing leg control and the support leg control. The trajectory of the swing foot is generated in realtime to regulate the walking speed. By considering the reaction torque of the swing leg’s hip joint as disturbance, a sliding model controller is implemented at the support leg’s hip joint to control the torso’s posture angle. In order to make sure the landing foot does not rebound after impact, the vertical contact force control is set as the internal loop of the hip’s height control. In simulation, the control system is tested on a virtual 5-link planar biped walker in Matlab. Finally, stable biped walking is realized on uneven terrain with roughness up to 2cm.

    Full Text Available Background/Aim. Accessory bones are most commonly found on the feet and they represent an anatomic variant. They occur when there is a failure in the formation of a unique bone from separated centre of ossification. The aim of this study was to establish their frequency and medical significance. Methods. Anteroposterior and lateral foot radiography was performed in 270 patients aged of 20-80 years with a history of trauma (180 and rheumatology disease (90. The presence and distribution of accessory bones was analysed in relation to the total number of patients and their gender. The results are expressed in numeric values and in terms of percentage. Results. Accessory bones were identified in 62 (22.96% patients: 29 (10.74% of them were found in female patients and 33 (12.22% in males. The most common accessory bones were as follows: os tibiale externum 50%, os peroneum 29.03%, ostrigonum 11.29%, os vaselianum 9.68%. Conclusion. Accessory bones found in 23% of patients with trauma and some of rheumatological diseases. Their significance is demonstrated in the differential diagnosis among degenerative diseases, avulsion fractures, muscle and tendon trauma and other types of injuries which can cause painful affection of the foot, as well as in forensic practice.

  20. A Cochrane review of the evidence for non-surgical interventions for flexible pediatric flat feet.

    2011-03-01

    The pediatric flat foot is a frequent presentation in clinical practice, a common concern to parents and continues to be debated within professional ranks. As an entity, it is confused by varied classifications, the notion of well-intended prevention and unsubstantiated, if common, treatment. The available prevalence estimates are all limited by variable sampling, assessment measures and age groups and hence result in disparate findings (0.6-77.9%). Consistently, flat foot has been found to normally reduce with age. The normal findings of flat foot versus children's age estimates that approximately 45% of preschool children, and 15% of older children (average age 10 years) have flat feet. Few flexible flat feet have been found to be symptomatic. Joint hypermobility and increased weight or obesity may increase flat foot prevalence, independently of age. Most attempts at classification of flat foot morphology include the arch, heel position and foot flexibility. Usual assessment methods are footprint measures, X-rays and visual (scaled) observations. There is no standardized framework from which to evaluate the pediatric flat foot. The pediatric flat foot is often unnecessarily treated, being ill-defined and of uncertain prognosis. Contemporary management of the pediatric flat foot is directed algorithmically within this review, according to pain, age, flexibility; considering gender, weight, and joint hypermobility. When foot orthoses are indicated, inexpensive generic appliances will usually suffice. Customised foot orthoses should be reserved for children with foot pain and arthritis, for unusual morphology, or unresponsive cases. Surgery is rarely indicated for pediatric flat foot (unless rigid) and only at the failure of thorough conservative management. The assessment of the pediatric flatfoot needs to be considered with reference to the epidemiological findings, where there is consensus that pediatric flexible flat foot reduces with age and that most children

    We present a descriptive, retrospective study of initial symptoms, comorbidity, and alcohol withdrawal in 73 alcoholic patients with subsequent Korsakoff syndrome. In 25/73 (35%) of the patients the classic triad of Wernicke's encephalopathy with ocular symptoms, ataxia and confusion, was found. In at least 6/35 (17%) of the initial deliria (95% confidence interval: 10-25%) we observed no other underlying causes, thus excluding other somatic causes, medication, (recent) alcohol withdrawal, or intoxication. We suggest that these deliria may have been representing Wernicke's encephalopathy. A high frequency (15%) of diabetics may reflect a contributing factor of diabetes mellitus in the evolution of the Wernicke-Korsakoff syndrome.

    Full Text Available Beta Glucan food supplements have been reported to be of benefit in diabetes and hyperlipidemia. We report a pilot study of the effects of Nichi Glucan, 1, 3-1, 6 Beta Glucan food supplement, in lowering the blood glucose and lipid levels in three patients with noninsulin-dependent diabetes mellitus (NIDDM from India. These patients had increased blood glucose and lipid levels inspite of routine antidiabetic and lipid level lowering medications. Each of the participants took 1.5 g of Nichi Glucan per day with food for two months along with their routine medications. The relevant parameters to assess glycemic status and lipid levels were calculated at the baseline and at the end of two months. After two months of continuous consumption, in one patient, the HbA1c decreased from 9.1% to 7.8%, and the glycemic target of HbA1c <6.5% laid down by the International Diabetes Federation was reached in two patients. Lipid levels also decreased significantly. Based on our findings, Nichi Glucan food supplement can be considered along with routine medications in patients with Type II diabetes with hyperlipidemia. Further studies are needed to validate the results.

    Objective. To assess the efficacy and acceptability of a group medical nutritional therapy (MNT) intervention, using motivational interviewing (MI). Research Design & Method. African American (AA) women with type 2 diabetes (T2D) participated in five, certified diabetes educator/dietitian-facilitated intervention sessions targeting carbohydrate, fat, and fruit/vegetable intake and management. Motivation-based activities centered on exploration of dietary ambivalence and the relationships between diet and personal strengths. Repeated pre- and post-intervention, psychosocial, dietary self-care, and clinical outcomes were collected and analyzed using generalized least squares regression. An acceptability assessment was administered after intervention. Results. Participants (n = 24) were mostly of middle age (mean age 50.8 ± 6.3) with an average BMI of 39 ± 6.5. Compared to a gradual pre-intervention loss of HbA1c control and confidence in choosing restaurant foods, a significant post-intervention improvement in HbA1c (P = 0.03) and a near significant (P = 0.06) increase in confidence in choosing restaurant foods were observed with both returning to pre-intervention levels. 100% reported that they would recommend the study to other AA women with type 2 diabetes. Conclusion. The results support the potential efficacy of a group MNT/MI intervention in improving glycemic control and dietary self-care-related confidence in overweight/obese AA women with type 2 diabetes.

    Full Text Available The molecular mechanism formation of secondary epiretinal membranes (ERMs after proliferative diabetic retinopathy (PDR or primary idiopathic ERMs is still poorly understood. Therefore, the present study focused on the assessment of IGF1, IGF1R, and IGFBP3 mRNA levels in ERMs and PBMCs from patients with PDR. The examined group comprised 6 patients with secondary ERMs after PDR and the control group consisted of 11 patients with idiopathic ERMs. Quantification of IGF1, IGF1R, and IGFBP3 mRNAs was performed by real-time QRT-PCR technique. In ERMs, IGF1 and IGF1R mRNA levels were significantly higher in patients with diabetes compared to control subjects. In PBMCs, there were no statistically significant differences of IGF1, IGF1R, and IGFBP3 expression between diabetic and nondiabetic patients. In conclusion, our study indicated IGF1 and IGF1R differential expression in ERMs, but not in PBMCs, of diabetic and nondiabetic patients, suggesting that these factors can be involved in the pathogenesis or progression of proliferative vitreoretinal disorders. This trial is registered with NCT00841334.

    The purpose of this study was to investigate 1) the effect of feet distance on static postural balance and 2) the location of natural feet distance and its possible role in the relationship of feet distance and postural balance. Static balance tests were performed on a force platform for 100 s with six different feet distances (0, 5, 10, 15, 20, 25 cm). Measures of postural balance included mean amplitude of horizontal ground reaction force (GRF) as well as the mean distance and velocity of the center of pressure (COP). All measures were discomposed into anterioposterior and mediolateral directions. ANOVA and post-hoc comparison were performed for all measures with feet distance as an independent factor. Also measured was the feet distance at the natural stance preferred by each subject. All measures significantly varied with feet distance (ppostural control) in an inverted pendulum model with the horizontal GRF ignored. On the other hand, horizontal GRF is the direct cause of horizontal acceleration of a center of mass. The present result on horizontal GRF shows that the effort of postural control is minimized around the feet distance of natural standing and implies why the natural stance is preferred.

    Purpose The purpose of this study is to develop and pilot an innovative behavioral intervention in adolescents with type 1 diabetes mellitus (T1DM) incorporating structured care of a pet to improve glycemic control. Methods Twenty-eight adolescents with A1C > 8.5% (69 mmol/mol) were randomly assigned to either the intervention group (care of a Betta splendens pet fish) or the control group (usual care). Adolescents in the intervention group were given instructions to associate daily and weekly fish care duties with diabetes self-management tasks including blood glucose testing and parent-adolescent communication. Results After 3 months the participants in the intervention group exhibited a statistically significant decrease in A1C levels (−0.5%) compared to their peers in the control group who had an increase in A1C levels (0.8%)(p = 0.04). The younger adolescents (ages 10–13) demonstrated a greater response to the intervention which was statistically significant (−1.5% vs. 0.6%, p = 0.04) compared with the older adolescents (ages 14–17). Conclusions Structured care of a pet fish can improve glycemic control in adolescents with T1DM, likely by providing cues to perform diabetes self-management behaviors. PMID:25614529

    Full Text Available Foot binding has a long and influential history in China. Little is known about biomechanical changes in gait caused by bound foot. The purpose of this study was to investigate the differences in lower limb kinematics between old women with bound feet and normal feet during walking. Six old women subjects (three with bound feet and three controls with normal feet volunteered to participate in this study. Video data were recorded with a high speed video camera and analysed in the SIMI motion analysis software. Compared to normal controls, bound feet subjects had faster gait cadence with shorter stride length as well as smaller ankle and knee range of motion (ROM. During preswing phase, ankle remained to be dorsiflexion for bound foot subjects. The data from bound foot group also demonstrated that toe vertical displacement increased continuously during whole swing phase without a minimum toe clearance (MTC. The findings indicate that older women with bound feet exhibit significant differences in gait pattern compared to those with normal feet, which is characterised by disappeared propulsion/push-off and reduced mobility of lower limb segments.

    Full Text Available Two feet motion is estimated for gait analysis. An inertial sensor is attached on each shoe and an inertial navigation algorithm is used to estimate the movement of both feet. To correct inter-shoe position error, a camera is installed on the right shoe and infrared LEDs are installed on the left shoe. The proposed system gives key gait analysis parameters such as step length, stride length, foot angle and walking speed. Also it gives three dimensional trajectories of two feet for gait analysis.

    Full Text Available CONTEXT AND OBJECTIVE: Physiotherapy can contribute towards recovering or preventing physical and sensory alterations in diabetic neuropathy patients. Our objective was to create and apply a protocol for functional assessment of diabetic neuropathy patients' lower limbs, to guide future physiotherapy. DESIGN AND SETTING: Clinical study at the University Hospital and teaching/research center of Universidade de São Paulo. METHODS: An intentional sample of diabetic neuropathy patients was utilized. The protocol was divided into: (1 preliminary investigation with identification of relevant clinical diabetes and neuropathy characteristics; (2 thermal, tactile and proprioceptive sensitivity tests on the feet; (3 evaluations of muscle function, range of motion, lower limb function, foot anthropometry. RESULTS: The patients' mean age was 57 years, and they had had the diagnosis for 13 years on average. Distal numbness and tingling/prickling were present in 62% and 67%, respectively. There were tactile sensitivity alterations above the heel in 50%, with thermal sensitivity in 40% to 60%. The worst muscle function test responses were at the triceps surae and foot intrinsic muscles. Longitudinal plantar arches were lowered in 50%. Decreased thermal and tactile sensitivity of the heels was found. There was a general reduction in range of motion. CONCLUSIONS: The results provided detailed characterization of the patients. This protocol may be easily applied in healthcare services, since it requires little equipment, at low cost, and it is well understood by patients.

    Heart rate variability (HRV) and haemorheology adaptations to 12 wk of varied-dose treadmill walking were investigated in women aged 65-74 yr with type 2 diabetes. Subjects were randomly allocated into two groups where exercise frequency and session duration were manipulated (Group 1: 2 × 60 min·wk(-1) or Group 2: 4 × 30 min·wk(-1)), but intensity and accumulated weekly duration of exercise were consistent between groups (100% gas-exchange threshold; 120 min·wk(-1)). Twelve weeks of exercise training significantly improved peak oxygen uptake, time to exhaustion, and gas-exchange threshold (p exercise group. Exercise training did not significantly change glycaemic control or body mass. Red blood cell (RBC) aggregation and RBC deformability significantly decreased (p exercise-only intervention and that exercise training improved RBC aggregation without a concomitant improvement in glycaemic control. The accumulated weekly exercise duration may be the most important training component for the prescription of exercise in older women with type 2 diabetes.

    Full Text Available Caudal epidural anesthesia in children is not performed in pure form, but only in combination with superficial general anesthesia. Therefore, a search for reliable evaluation criteria of the caudal epidural block onset in children remains actual. Aim. To evaluate effectiveness of caudal epidural anesthesia efficacy by measurement of feet skin temperature in children. Methods and results. We investigated feet skin temperature before the caudal blockade by bupivacaine and after 15–20 minutes in 30 children. The control group included 20 children who underwent total intravenous anesthesia. The study showed that feet skin temperature after caudal blockade significantly increased from 30,1±0,15°C to 33,0±0,1°C (10% and in the control group it did not change significantly. Conclusion. Thus, feet skin thermometry may be considered to be a reliable non-invasive method for assessing the onset of the caudal block.

    The complex functions of feet require a specific composition, which is progressively achieved by developmental processes. This development should take place without being affected by footwear. The aim of this study is to evaluate differences between static and dynamic foot morphology in developing feet. Feet of 2554 participants (6-16 years) were recorded using a new scanner system (DynaScan4D). Each foot was recorded in static half and full weight-bearing and during walking. Several foot measures corresponding to those used in last construction were calculated. The differences were identified by one-way ANOVA and paired Student's t-test. Static and dynamic values of each foot measure must be considered to improve the fit of footwear. In particular, footwear must account for the increase of forefoot width and the decrease of midfoot girth. Furthermore, the toe box should have a more rounded shape. The findings are important for the construction of footwear for developing feet.

    Common warts (verruca vulgaris) are the most commonly seen benign cutaneous tumors. However, warts in the hands and feet regions often respond poorly to treatment, some are resistant to more than 6 months of treatment with currently available modalities, including cryotherapy, being defined as refractory warts. We investigated the usefulness of long-pulsed neodymium:yttrium-aluminum-garnet (LP-Nd:YAG) treatment for refractory warts. The clinical trial was conducted on 20 subjects (11 male, nine female) with a total of 34 lesions (periungual/subungual areas, plantar areas, fingers and/or toes). All the subjects suffered from refractory warts despite conventional treatments for more than 6 months. The patients were administrated up to six sessions of treatment, at intervals of 4 weeks between sessions, with an LP-Nd:YAG at a spot size of 5 mm, pulse duration of 15 msec and fluence of 150-185 J/cm(2) . Evaluation of the treatment results at 24 weeks after the initial treatment showed complete clearance of the refractory warts in 56% of the patients. Histological evaluation showed separation of the dermis and epidermis at the basement membrane with coagulated necrosis of the wart tissue in the lower epidermis, as well as coagulation and destruction of the blood vessels in the papillary dermis following the laser irradiation. No scarring, post-hyperpigmentary changes or serious adverse events were documented. Our preliminary results show that LP-Nd:YAG treatments are safe and effective for refractory warts of hands and feet, causing minimal discomfort, and is a viable treatment alternative. © 2014 Japanese Dermatological Association.

    Incubation in most avian species involves transferring heat from parent to egg through a highly vascularized brood patch. Some birds, however, do not develop a brood patch. Unusual among birds, these species hold their eggs under the webs of their feet, but the role of the feet in heat transfer is uncertain. Often the webs are positioned between the feathered abdomen and the egg during incubation, suggesting that either the abdomen, the feet, or both could transfer heat to the egg. We studied heat transfer from foot webs to eggs during incubation in Nazca boobies by spatially separating the feet from the abdomen using an oversized egg. We found that feet transfer heat to eggs independently of any heat that may be transferred from the abdomen. In addition, we found that incubating boobies had significantly greater vascularization in their foot webs, measured as a percentage of web area covered by vessels, than nonincubating boobies. We also found that males, whether incubating or nonincubating, had significantly less web vascularization than females. We concluded that vascularized Nazca booby feet function in the same way during incubation that vascularized brood patches do, acting as surrogate brood patches.

    The electronic personal health record (PHR) is a promising technology for improving the quality of chronic disease management. Until now, evaluations of such systems have provided only little insight into why a particular outcome occurred. The aim of this study is to gain insight into the navigation process (what functionalities are used, and in what sequence) of e-Vita, a PHR for patients with type 2 diabetes mellitus (T2DM), to increase the efficiency of the system and improve the long-term adherence. Log data of the first visits in the first 6 weeks after the release of a renewed version of e-Vita were analyzed to identify the usage patterns that emerge when users explore a new application. After receiving the invitation, 28% of all registered users visited e-Vita. In total, 70 unique usage patterns could be identified. When users visited the education service first, 93% of all users ended their session. Most users visited either 1 or 5 or more services during their first session, but the distribution of the routes was diffuse. In conclusion, log file analyses can provide valuable prompts for improving the system design of a PHR. In this way, the match between the system and its users and the long-term adherence has the potential to increase.

    Diabetic foot is one of the major complications experienced by diabetic patients. An early identification and appropriate treatment of diabetic foot problems can prevent devastating consequences such as limb amputation. Several studies have demonstrated that temperature variations in the plantar region can be related to diabetic foot problems. Infrared thermography has been successfully used to detect complication related to diabetic foot, mainly because it is presented as a rapid, non-contact and non-invasive technique to visualize the temperature distribution of the feet. In this review, an overview of studies that relate foot temperature with diabetic foot problems through infrared thermography is presented. Through this research, it can be appreciated the potential of infrared thermography and the benefits that this technique present in this application. This paper also presents the different methods for thermogram analysis and the advantages and disadvantages of each one, being the asymmetric analysis the method most used so far.

    Sensory testing in people affected by Hansen's disease is usually performed on palms and soles only. In Israel, both palmar/plantar and dorsal aspects of limbs are routinely tested. The aim of this study was to describe the magnitude of dorsal sensory impairment (SI) in limbs and compare the frequency of SI on palms and soles with that on the dorsum of hands and feet. In a cross-sectional study, limbs of 140 patients registered at The Israel Hansen's Disease Centre during the years 1999-2003 were tested for their sensory status. Both palmar/plantar and dorsal aspects were tested using Semmes-Weinstein monofilaments. SI was defined as not feeling stimuli applied with the 2 g monofilament. SI was detected on the dorsum in 43% of sites on hands and only in 27% on palms. 64% of sites on dorsum of feet had SI compared to 53% on the soles. SI was detected in up to 18% in hands with no palmar SI, and in 6% of feet with no plantar SI. Furthermore, SI on palms and soles was found to be accompanied by dorsal SI in all hands and in 97% of feet. SI on dorsum of limbs occurs more frequently than SI on palms and soles. Therefore sensory testing should also consider inclusion of the dorsal aspect of hands and feet.

  16. Radiological residua of healed diabetic arthropathies

    Energy Technology Data Exchange (ETDEWEB)

    Reinhardt, K.

    1981-12-01

    Diabetic arthropathy is a relatively rare manifestation of neuropathic disease, occurring in fewer than 5% of cases. Abnormalities of this type are confined largely to the small joints of the feet, although the larger joints of the lower limbs and the spine occasionally are affected. Some lesions, particularly in the feet, repair spontaneously, leaving radiological residua sufficiently characteristic to prompt suspicion of an unrecognised diabetic state. These include deformity of the head of the second metatarsal (akin to a Freiberg lesion), shortening of the great toe, painless deforming arthrosis of the knee, and ankylosis of interphalangeal joints. In the presence of these signs the patient should be interrogated concerning diabetes and blood sugar estimates, with provocation if necessary, obtained. Should such a diagnosis be sustained, appropriate protective measures may be undertaken to avoid a relapse of the arthropathy.

    The alcohol drinking at the young age is a risk factor of alcohol addiction later in life, and is connected with school problems, binge drinking, tobacco addiction, illegal drug use, violence, crime commitment, and risky sexual behaviors. Alcohol drinking in the last 12 months is declared by 78% Polish children. The aim of the study was to evaluate the frequency of admissions due to alcohol intoxication to the Department of Pediatrics, Pediatric Endocrinology and Diabetes, Pediatric Center of Silesia and the identification of the risk factors of the acute alcohol intoxication among Polish children and adolescents. Ten-year retrospective study includes investigation of patients medical records from the Department of Pediatrics. Among 8048 patients hospitalized in the Department of Pediatrics between the years 2000-2010, 220 (2.7%) cases of acute alcohol poisoning occurred The detailed data analysis from 139 patients [66 (47.5%) girls, 73 (52,5%) boys] was done. In the years 2006-2010 the number of girls admitted to the department increased in comparison to boys. The largest group of patients was at age between 14 and 16 years [61 (44%) children]. The blood alcohol concentration at the moment of admission to the hospital was 0.1 to 4.0 per thousand. In most cases (92.8%) the alcohol intoxication was intentional. Five percent of them were suicide attempts. In the youngest group of children alcohol abuse was unintentional. 23 (16.5%) of patients initially needed admission to the intensive care unit. In 30 (21.6%) patient the family was incomplete and five times more often father was absent. The alcohol addiction occurs in 18 (13.0%) fathers and 10 (7.2%) mothers of our patients. It is concluded that over the last decade the number of girls admitted due to alcohol abuse increased. Children at school grade between 7-9 are intoxicated most often. One six of intoxicated patents needed hospitalization at intensive care unit.

    Full Text Available Ruminants live in various parts of land. Similar cloven hooves assist ruminants in adapting to different ground environment during locomotion. This paper analyzes the general terrain adaptability of the feet of ruminants using kinematics of the equivalent mechanism model based on screw theory. Cloven hooves could adjust attitude by changing relative positions between two digits in swing phase. This function helps to choose better landing orientation. “Grasping” or “holding” a rock or other object on the ground passively provides extra adhesion force in stance phase. Ruminants could adjust the position of the metacarpophalangeal joint or metatarsophalangeal joint (MTP or MCP with no relative motion between the tip of feet and the ground, which ensures the adhesion and dexterity in stance phase. These functions are derived from an example from chamois’ feet and several assumptions, which are believed to demonstrate the foundation of adaptation of ruminants and ensure a stable and continuous movement.

    Aims. This study aimed to assess whether the electrochemical skin conductance (ESC) could be used to screen for diabetic cardiac autonomic neuropathy (DCAN) in a Chinese population with diabetes. Methods. We recruited 75 patients with type 2 diabetes mellitus (T2DM) and 45 controls without diabetes. DCAN was diagnosed by the cardiovascular autonomic reflex tests (CARTs) as gold standard. In all subjects ESCs of hands and feet were also detected by SUDOSCAN™ as a new screening method. The efficacy was assessed by receiver operating characteristic (ROC) curve analysis. Results. The ESCs of both hands and feet were significantly lower in T2DM patients with DCAN than those without DCAN (67.33 ± 15.37 versus 78.03 ± 13.73, P = 0.002, and 57.77 ± 20.99 versus 75.03 ± 11.41, P diabetes before further diagnosis with CARTs.

    The nanometer size of the tiny hair is the key to the secret of strong stickiness of gecko's feet, by which the hair can achieve the maximum adhesion strength that is insensitive to the interfacial flaws with substrate surface. But the question why the hairs have not been smaller is not answered yet. In this study, we derived a geometric parameter of the surface structures considering lateral interaction among hairs, which gives a critical size below which these hairs will bunch together and cause failure of the adhesion, suggesting a lower limit of the dimension of hairs on gecko's feet.

  3. A novel aromatic oil compound inhibits microbial overgrowth on feet: a case study

    Full Text Available Abstract Background Athlete's Foot (Tinea pedis is a form of ringworm associated with highly contagious yeast-fungi colonies, although they look like bacteria. Foot bacteria overgrowth produces a harmless pungent odor, however, uncontrolled proliferation of yeast-fungi produces small vesicles, fissures, scaling, and maceration with eroded areas between the toes and the plantar surface of the foot, resulting in intense itching, blisters, and cracking. Painful microbial foot infection may prevent athletic participation. Keeping the feet clean and dry with the toenails trimmed reduces the incidence of skin disease of the feet. Wearing sandals in locker and shower rooms prevents intimate contact with the infecting organisms and alleviates most foot-sensitive infections. Enclosing feet in socks and shoes generates a moisture-rich environment that stimulates overgrowth of pungent both aerobic bacteria and infectious yeast-fungi. Suppression of microbial growth may be accomplished by exposing the feet to air to enhance evaporation to reduce moistures' growth-stimulating effect and is often neglected. There is an association between yeast-fungi overgrowths and disabling foot infections. Potent agents virtually exterminate some microbial growth, but the inevitable presence of infection under the nails predicts future infection. Topical antibiotics present a potent approach with the ideal agent being one that removes moisture producing antibacterial-antifungal activity. Severe infection may require costly prescription drugs, salves, and repeated treatment. Methods A 63-y female volunteered to enclose feet in shoes and socks for 48 hours. Aerobic bacteria and yeast-fungi counts were determined by swab sample incubation technique (1 after 48-hours feet enclosure, (2 after washing feet, and (3 after 8-hours socks-shoes exposure to a aromatic oil powder-compound consisting of arrowroot, baking soda, basil oil, tea tree oil, sage oil, and clove oil.

    We applied aluminum hinged shoes (AHSs) to the club foot-associated contracted feet of 11 Thoroughbred yearlings to examine the effects of the shoes on the shape of the hoof and third phalanx (P III). After 3 months of AHS use, the size of the affected hooves increased significantly, reaching the approximate size of the healthy contralateral hooves with respect to the maximum lateral width of the foot, the mean ratio of the bearing border width to the coronary band width, and the mean ratio of the solar surface width to the articular surface width. These results suggest that the AHSs corrected the contracted feet in these yearling horses.

    To compare visual and anatomical outcomes between intravitreous bevacizumab (BVB, Avastin) and triamcinolone (TA, Triesence) when administered at the time of cataract surgery in patients with diabetic macular oedema (DME). Prospective, single-masked, randomized clinical trial at The Royal Victorian Eye and Ear Hospital, Melbourne. Patients with clinically significant cataract and either centre-involving DME or DME treated within the previous 24 months. Participants were randomized 1:1 to receive intravitreous BVB 1.25 mg or TA 4 mg during cataract surgery, and at subsequent review if required over 6 months. Change in central macular thickness (CMT) and best corrected visual acuity at 6 months. Forty-one patients (mean age 66.4 years, 73.2% male) were recruited. Visual acuity and CMT were similar between groups at baseline (P > 0.2).After six months, both groups gained vision (mean +21.4 letters in TA group P < 0.0001, +12.5 letters in BVB, P = 0.002), with no significant difference between groups (P = 0.085). In addition, 60.9% of eyes receiving TA achieved a VA of ≥6/12 compared to 73.3% in the BVB group (P = 0.501). However, only TA was associated with a sustained reduction in CMT (-43.8-µm reduction TA vs. +37.3-µm increase BVB, P = 0.006 over 6 months). Following surgery, additional injections were required in 70.6% of participants in the BVB group, compared to 16.7% in the TA group (P < 0.0001). Three patients in the TA group experienced a rise of IOP over 21 mmHg (12.5%) during the 6-month follow-up; BVB had no cases (P = 0.130). There were no cases of endophthalmitis in either group. When administered at the time of cataract surgery in patients with DME, at 6 months both TA and BVB improve visual acuity; however, only TA results in a sustained reduction in CMT. Further follow-up will determine whether this translates into better long-term visual outcomes in the TA group. © 2016 Royal Australian and New

  7. Foot Placement Modification for a Biped Humanoid Robot with Narrow Feet

    Directory of Open Access Journals (Sweden)

    Kenji Hashimoto

    2014-01-01

    Full Text Available This paper describes a walking stabilization control for a biped humanoid robot with narrow feet. Most humanoid robots have larger feet than human beings to maintain their stability during walking. If robot’s feet are as narrow as humans, it is difficult to realize a stable walk by using conventional stabilization controls. The proposed control modifies a foot placement according to the robot's attitude angle. If a robot tends to fall down, a foot angle is modified about the roll axis so that a swing foot contacts the ground horizontally. And a foot-landing point is also changed laterally to inhibit the robot from falling to the outside. To reduce a foot-landing impact, a virtual compliance control is applied to the vertical axis and the roll and pitch axes of the foot. Verification of the proposed method is conducted through experiments with a biped humanoid robot WABIAN-2R. WABIAN-2R realized a knee-bended walking with 30 mm breadth feet. Moreover, WABIAN-2R mounted on a human-like foot mechanism mimicking a human's foot arch structure realized a stable walking with the knee-stretched, heel-contact, and toe-off motion.

    To investigate effect of feet orientation on the evaluation of the postural stability in patients with unilateral vestibular hypofunction (UVH) by timed standing tests and static posturography (SPG). Methods 65 subjects with UVH and 92 healthy subjects regarded as control group took the posrural stability tests in four different stances including (1) standard Romberg test, (2) feet-apart stance test, (3) tandem and (4) unilateral standing tests. In each stance, the postural stability was measured in both eyes open (EO) and eyes closed(EC) conditions. The average time that subjects kept balance before falling in each test conditions was recorded by stopwatch as the timed result. In addition, the sway velocity (SV) of center of foot pressure in the upright stance during standard Romberg test and feet apart stance, regarded as postural stability, was also recorded as SPG. Results (1) The balance-maintain-ing time of the UVH group in tandem and unilateral standing with EO and EC was decreased (P 0.05). Conclusions The results suggest that the tandem and unilateral stance tests may provide additional information about the upright stance to the SPG measurement in patients with UVH. The effect of feet orientation on SPG measurements should be considered.

  18. Dynamic Characteristics of Prosthetic Feet: A Comparison Between Modal Parameters of Walking, Running and Sprinting Foot

    Science.gov (United States)

    Noroozi, S.; Rahman, A. G. A.; Dupac, M.; Vinney, J. E.

    Current methods of evaluating the performance of Energy Storing and Returning (ESR) prosthesis are subjective and rely on VO2 consumption. Current prosthetic feet are designed for specific applications and the majority are designed for walking and moderate running. These mechanical feet have fixed mechanical and dynamic characteristics. They have to be selected to meet the requirement of the task and any use outside the domain of the task can result in extreme/severe lack of gait symmetry and loss of energy. Poor gait symmetry results is excess consumption of energy, back pain or fatigue. To investigate if a multipurpose foot can be designed to passively adapt to the walking or running condition one must first understand the different dynamics that are involved and are required from the task specific foot. Static tests have shown these feet to have non-linear stiffness, making the prediction of their dynamic response difficult. The most reliable method to test for dynamic characteristics is drop and modal testing. A method approach has been developed as part of this research to test and compare the dynamic characteristics of three different types of foot (natural frequency, mode shapes and damping). This is needed to explore the differences in the responses of these feet that allow one to be used for walking, one to be used for running and one to be used for sprinting with ease.

    Katia López-Revuelta

    2015-07-01

    Full Text Available Diabetic nephropathy without diabetes (DNND, previously known as idiopathic nodular glomerulosclerosis, is an uncommon entity and thus rarely suspected; diagnosis is histological once diabetes is discarded. In this study we describe two new cases of DNND and review the literature. We analyzed all the individualized data of previous publications except one series of attached data. DNND appears to be favored by recognized cardiovascular risk factors. However, in contrast with diabetes, apparently no factor alone has been demonstrated to be sufficient to develop DNND. Other factors not considered as genetic and environmental factors could play a role or interact. The most plausible hypothesis for the occurrence of DNND would be a special form of atherosclerotic or metabolic glomerulopathy than can occur with or without diabetes. The clinical spectrum of cardiovascular risk factors and histological findings support this theory, with hypertension as one of the characteristic clinical features.

    2015-09-01

    Full Text Available Background: A flexible flatfoot is considered to be a variation of a normal foot. Any deviation from the anatomical plantigrade foot is a deformed foot. Some of the deformities of the foot are: Flat Foot. The normal concavity due to the medial longitudinal arch is absent. High Arch Foot - A normal foot has a medial longitudinal arch which is higher. Materials and Methods: A total population of 625, in age ranging from 5 year to 9 years in Kanchipuram district was chosen. Each individual was made to sit and the foot was brought in contact with the Foot Impression gaining Kit on white sheets in standing posture. Results: The flat feet and high arch feet evaluation was obtained by means of foot prints and the plantar arch index was established. The mean values of plantar arch index within the age group were stable and ranges from 0.72 to 0.73. With plantar arch indices greater than 1.15 was regarded as flatfeet and less than 0.10 was regarded as High arch feet. Discussion: In normal feet with presence of an arch, the stress will be distributed in an even manner so that the person will not experience any kind of pain. Under an abnormal condition that occurs due to lack of stretching of muscles, bones and tendons, there will be absence of arch among these people. In this condition, all the weight will be concentrated in smaller area on the feet and generates a lot more pain than normal. This condition might occur in both children and adults. In some people both feet will be flat and in some only one foot will be flat. Conclusion: Flat foot is highly prevalent in the ages between 5-9. The average values for plantar arch indices are stable and ranges from 0.72 to 0.73 in our sample regarded as Normal foot. Plantar arch index > 1.15 is regarded as Flat foot. Plantar arch index < 0.10 is regarded as High arch foot.

    2012-10-01

    Passive dynamic walking has been developed as a possible explanation for the efficiency of the human gait. This paper presents a passive dynamic walking model with segmented feet, which makes the bipedal walking gait more close to natural human-like gait. The proposed model extends the simplest walking model with the addition of flat feet and torsional spring based compliance on ankle joints and toe joints, to achieve stable walking on a slope driven by gravity. The push-off phase includes foot rotations around the toe joint and around the toe tip, which shows a great resemblance to human normal walking. This paper investigates the effects of the segmented foot structure on bipedal walking in simulations. The model achieves satisfactory walking results on even or uneven slopes.

    2013-05-01

    Full Text Available Abstract If humanoid robots are to be used in society, they should be able to maintain their balance. Knowing where to step is crucially important. In this paper we contribute an algorithm that can compute the foot step location such that bipedal balance is maintained for planar bipeds with point feet and an arbitrary number of non-massless links on a horizontal and flat ground. The algorithm is called the foot placement indicator (FPI and it extends the foot placement estimator (FPE. The FPE uses an inverted pendulum model to capture the dynamics of a humanoid robot, whereas the FPI deals with multi-body models with distributed masses. This paper analyses equilibrium sets and the stability of planar bipeds with point feet. The algorithm uses conservation of energy throughout the step, taking into account the instantaneous impact dynamics at foot strike. A simulation case study on a five-link planar biped shows the effectiveness of the FPI.

    This study scientifically measures the dynamic gait characteristics and energy consumption of 16 male below-knee amputees, eight vascular and eight traumatic, while wearing solid ankle cushion heel (SACH), single axis and multiple axis prosthetic feet via six-camera motion analysis, metabolic measurement cart and heavy-duty treadmill. Subjective results are additionally determined via questionnaire after testing. Motion analysis showed statistically significant differences at Pmultiple axis foot in the velocity, cadence, stride length and single limb stance. Significant differences were found in energy consumption between the traumatic and vascular groups, and significant changes in walking under different speeds and different inclines. Results provide quantitative and qualitative information about the dynamic performance of the various feet, which can be helpful in prescribing the optimal prosthetic foot for individual amputees.

    Most current biped robots are equipped with two feet arranged in the right and left which inspired by the human body system. Different from the existing configurations, a novel biped robot with inner and outer feet based on a spatial six-bar 4R2C(R and C denote revolute and cylindric joints, respectively) mechanism is proposed. It can move along a line or a curve by three walking modes that are dwell adjustment mode, limit position adjustment mode and any position adjustment mode. Kinematic, gait planning and stability analyses are performed respectively, and a prototype is developed. Lastly, a potential application is considered and two manipulating modes(sphere and cylinder manipulating modes) are carried out. This interesting mechanism feathering its single closed-chain structure and unique work performance is expected to motivate the configuration creation of biped robots.

    To examine the relationship between obesity, genu valgum, and flat feet in children, and find practical implications for therapeutic interventions. A total of 1364 children aged 3-7 years took part in the research. Their body mass index was calculated and their weight status described. Participants' knee alignment was assessed by measuring the intermalleolar distance in the standing position with the knees in contact. The height of the longitudinal arch of each foot was measured using Clarke's angle. The prevalence of overweight and obesity increased with age. Reduction of intermalleolar distance and increased longitudinal arch of the foot, characteristic of typical growth and development, were observed. Genu valgum was more common in children who were overweight. Significant correlations among body mass index, intermalleolar distance, and Clarke's angle (P genu valgum and flat feet.

    During dynamic walking of biped robots, the underactuated rotating degree of freedom (DOF) emerges between the support foot and the ground, which makes the biped model hybrid and dimension-variant. This paper addresses the asymptotic orbit stability for dimension-variant hybrid systems (DVHS). Based on the generalized Poincare map, the stability criterion for DVHS is also presented, and the result is then used to study dynamic walking for a five-link planar biped robot with feet. Time-invariant gait planning and nonlinear control strategy for dynamic walking with flat feet is also introduced. Simulation results indicate that an asymptotically stable limit cycle of dynamic walking is achieved by the proposed method.

    Full Text Available This paper presents a detailed dynamic modeling of realistic four-legged robot. The direct and inverse kinematic analysis for each leg has been considered in order to develop an overall kinematic model of the robot, when it follows a straight path. This study also aims to estimate optimal feet force distributions of the said robot, which is necessary for its real-time control. Three different approaches namely, minimization of norm of feet forces (approach 1, minimization of norm of joint torques (approach 2 and minimization of norm of joint power (approach 3 have been developed. Simulation result shows that approach 3 is more energy efficient foot force formulation than other two approaches. Lagrange-Euler formulation has been utilized to determine the joint torques. The developed dynamic models have been examined through computer simulation of continuous gait of the four-legged robot.

    The risk of falls from height on a construction site increases under conditions which degrade workers' postural control. At elevation, workers depend heavily on sensory information from their feet to maintain balance. The study tested two hypotheses: "sensory enhancement"--sub-sensory (undetectable) random mechanical vibrations at the plantar surface of the feet can improve worker's balance at elevation; and "sensory suppression"--supra-sensory (detectable) random mechanical vibrations can have a degrading effect on balance in the same experimental settings. Six young (age 20-35) and six aging (age 45-60) construction workers were tested while standing in standard and semi-tandem postures on instrumented gel insoles. The insoles applied sub- or supra-sensory levels of random mechanical vibrations to the feet. The tests were conducted in a surround-screen virtual reality system, which simulated a narrow plank at elevation on a construction site. Upper body kinematics was assessed with a motion-measurement system. Postural stability effects were evaluated by conventional and statistical mechanics sway measures, as well as trunk angular displacement parameters. Analysis of variance did not confirm the "sensory enhancement" hypothesis, but provided evidence for the "sensory suppression" hypothesis. The supra-sensory vibration had a destabilizing effect, which was considerably stronger in the semi-tandem posture and affected most of the sway variables. Sensory suppression associated with elevated vibration levels on a construction site may increase the danger of losing balance. Construction workers at elevation, e.g., on a beam or narrow plank might be at increased risk of fall if they can detect vibrations under their feet. To reduce the possibility of losing balance, mechanical vibration to supporting structures used as walking/working surfaces should be minimized when performing construction tasks at elevation.

    Daily quality assurance procedures are an essential part of radiotherapy medical physics. Devices such as the Sun Nuclear, DQA3 are effective tools for analysis of daily dosimetry including flatness, symmetry, energy, field size and central axis radiation dose measurement. The DQA3 can be used on the treatment couch of the linear accelerator or on a dedicated table/bed for superficial and orthovoltage x-ray machines. This device is levelled using its dedicated feet. This work has shown that depending on the quantity of backscatter material behind the DQA3 device, the position of the levelling feet can affect the measured central axis dose by up to 1.8 % (250 kVp and 6 MV) and that the introduction of more backscatter material behind the DQA3 can lead to up to 7.2 % (6 MV) variations in measured central axis dose. In conditions where no backscatter material is present, dose measurements can vary up to 1 %. As such this work has highlighted the need to keep the material behind the DQA3 device constant as well as maintaining the accuracy of the feet position on the device to effectively measure the most accurate daily constancy achievable. Results have also shown that variations in symmetry and energy calculations of up to 1 % can occur if the device is not levelled appropriately. As such, we recommend the position of the levelling feet on the device be as close as possible to the device so that a constant distance is kept between the DQA3 and the treatment couch and thus minimal levelling variations also occur. We would also recommend having no extra backscattering material behind the DQA3 device during use to minimise any variations which might occur from these backscattering effects.

    Full Text Available Background: The dorsal aspect of the hallux is often cited as the anatomic location of choice for vibration testing in the feet of diabetic patients. To validate this preference, vibration tests were performed and compared at the hallux and 5th metatarsal head in diabetic patients with established neuropathy. Methods: Twenty-eight neuropathic, diabetic patients and 17 non-neuropathic, non-diabetic patients underwent timed vibration testing (TVT with a novel 128 Hz electronic tuning fork (ETF at the hallux and 5th metatarsal head. Results: TVT values in the feet of diabetic patients were found to be reduced at both locations compared to controls. Unexpectedly, these values were significantly lower at the hallux (P < 0.001 compared to the 5th metatarsal head. Conclusion: This study confirms the hallux as the most appropriate location for vibration testing and implies relative sensory sparing at the 5th metatarsal head, a finding not previously reported in diabetic patients.

    Peripersonal space (PPS) is the space surrounding us within which we interact with objects. PPS may be modulated by actions (e.g. when using tools) or sense of ownership (e.g. over a rubber hand). Indeed, intense and/or prolonged use of a tool may induce a sense of ownership over it. Conversely, inducing ownership over a rubber hand may activate brain regions involved in motor control. However, the extent to which PPS is modulated by action-dependent or ownership-dependent mechanisms remains unclear. Here, we explored the PPS around the feet and the sense of ownership over lower limbs in people with Paraplegia following Complete spinal cord Lesions (PCL) and in healthy subjects. PCL people can move their upper body but have lost all sensory-motor functions in their lower body (e.g. lower limbs). We tested whether PPS alterations reflect the topographical representations of various body parts. We found that the PPS around the feet was impaired in PCL who however had a normal representation of the PPS around the hands. Significantly, passive mobilization of paraplegic limbs restored the PPS around the feet suggesting that activating action representations in PCL brings about short-term changes of PPS that may thus be more plastic than previously believed.

    The Achilles tendon has been shown to be comprised of segmental components of tendon arising from the tricpes surae muscle group. Motion of the foot joints in low and high arched feet may induce a change in behaviour of the triceps surae muscle group due to altered strain on the tendon. Surface electromyogram of the medial and lateral gastrocnemius and the soleus muscle from 12 subjects (with 6 low arched and 6 high arched feet) (1:1) was recorded whilst walking at a self selected speed along a 10m walkway. The results showed a high variability in muscle activity between groups with patterns emerging within groups. Soleus was more active in 50% of the low arch feet at forefoot loading and there was a crescendo of activity towards heel lift in 58% of all subjects. This observed variability between groups and foot types emphasises the need for further work on individual anatomical variation and foot function to help in the understanding and management of Achilles tendon pathologies and triceps surae dysfunction.

    The Cold Pressor Test (CPT) is a frequently employed laboratory stress protocol. However, with many experimental designs the application in its classic form (immersion of the dominant hand into ice-water) is problematic as unilateral stimulation may need to be avoided and/or hands are required for further measurements. Here, we describe a simple modification of the classic CPT in which both feet are immersed into ice-water and compare the evoked neuroendocrine stress response to the classic CPT in a within-subjects design. Twenty-four healthy participants were exposed to each of both CPT versions on two subsequent days in randomized order. Heart rate, blood pressure, salivary alpha-amylase and cortisol were measured at baseline and during or after CPT exposition, respectively, along with subjective ratings of pain and stress. The bilateral feet CPT induced marked increases in all measured stress parameters. Moreover, with the exception of blood pressure, autonomic and endocrine responses were enhanced compared to the classic CPT. The bilateral feet CPT thus is a valid and simple modification and may be useful when the application of the classic CPT is unfeasible or a stronger neuroendocrine stress response is of interest.

  2. Evidence for rotational motions in the feet of a quiescent solar prominence

    We present observational evidence of apparent plasma rotational motions in the feet of a solar prominence. Our study is based on spectroscopic observations taken in the He I 1083.0 nm multiplet with the Tenerife Infrared Polarimeter attached to the German Vacuum Tower Telescope. We recorded a time sequence of spectra with 34 s cadence placing the slit of the spectrograph almost parallel to the solar limb and crossing two feet of an intermediate size, quiescent hedgerow prominence. The data show opposite Doppler shifts, +/- 6 km/s, at the edges of the prominence feet. We argue that these shifts may be interpreted as prominence plasma rotating counterclockwise around the vertical axis to the solar surface as viewed from above. The evolution of the prominence seen in EUV images taken with the Solar Dynamic Observatory provided us clues to interpret the results as swirling motions. Moreover, time-distance images taken far from the central wavelength show plasma structures moving parallel to the solar limb with ve...

    Percutaneous local ablation of osteoid osteoma has largely replaced surgery, except in the small bones of the hands and feet. The objective of this study was to describe the technical specificities and results of computed tomography (CT)-guided percutaneous laser photocoagulation in 15 patients with osteoid osteomas of the hands and feet. We retrospectively examined the medical charts of the 15 patients who were treated with CT-guided percutaneous laser photocoagulation therapy at our institution between 1994 and 2004. The 15 patients had a mean age of 24.33 years. None of them had received any prior surgical or percutaneous treatment for the osteoid osteoma. The follow-up period was 24 to 96 months (mean, 49.93). The pain resolved completely within 1 week. Fourteen patients remained symptom-free throughout the follow-up period; the remaining patient experienced a recurrence of pain after 24 months, underwent a second laser photocoagulation procedure, and was symptom-free at last follow-up 45 months later. No adverse events related to the procedure or to the location of the tumor in the hand or the foot were recorded. CT-guided percutaneous laser photocoagulation is an alternative to surgery for the treatment of osteoid osteomas of the hands and feet. (orig.)

    Pes planovalgus (flatfoot) is a common deformity among children with cerebral palsy. The Milwaukee Foot Model (MFM), a multi-segmental kinematic foot model, which uses radiography to align the underlying bony anatomy with reflective surface markers, was used to evaluate 20 pediatric participants (30feet) with planovalgus secondary to cerebral palsy prior to surgery. Three-dimensional kinematics of the tibia, hindfoot, forefoot, and hallux segments are reported and compared to an age-matched control set of typically-developing children. Most results were consistent with known characteristics of the deformity and showed decreased plantar flexion of the forefoot relative to hindfoot, increased forefoot abduction, and decreased ranges of motion during push-off in the planovalgus group. Interestingly, while forefoot characteristics were uniformly distributed in a common direction in the transverse plane, there was marked variability of forefoot and hindfoot coronal plane and hindfoot transverse plane positioning. The key finding of these data was the radiographic indexing of the MFM was able to show flat feet in cerebral palsy do not always demonstrate more hindfoot eversion than the typically-developing hindfoot. The coronal plane kinematics of the hindfoot show cases planovalgus feet with the hindfoot in inversion, eversion, and neutral. Along with other metrics, the MFM can be a valuable tool for monitoring kinematic deformity, facilitating clinical decision making, and providing a quantitative analysis of surgical effects on the planovalgus foot.

    No data are available for normative values of cutaneous threshold and spatial discrimination in the feet. We developed clinically applicable reference values in relation to the nerve distributions of the feet. We determined foot sensation in 196 healthy individuals. Cutaneous threshold (1-point static discrimination, S1PD) was tested with monofilaments (0.008 to 300 gram) and spatial discrimination (2-point static [S2PD] and moving [M2PD] discrimination) on five locations per foot. There was a significant age-dependent increase in S1PD, S2PD, and M2PD values (P < 0.05). No significant differences were found between both feet. S1PD values differed up to 0.8 g between genders. There were no significant differences between genders for S2PD and M2PD measurements. M2PD values were generally lower than S2PD values. This study provides age-related normative values for foot sensation to help clinicians assess sensory deficits in relation to aging and identify patients with underlying nerve problems.

    Diabetic peripheral neuropathy (DPN) refers to the nerve damage that can occur in diabetes patients. It most often affects the extremities, such as the feet, and can lead to peripheral vascular disease, deformity, infection, ulceration, and even amputation. The key to managing diabetic foot is prevention and early detection. Unfortunately, current existing diagnostic techniques are mostly based on patient sensations and exhibit significant inter- and intra-observer differences. We have developed a computer aided diagnostic (CAD) system for diabetic peripheral neuropathy. The thermal response of the feet of diabetic patients following cold stimulus is captured using an infrared camera. The plantar foot in the images from a thermal video are segmented and registered for tracking points or specific regions. The temperature recovery of each point on the plantar foot is extracted using our bio-thermal model and analyzed. The regions that exhibit abnormal ability to recover are automatically identified to aid the physicians to recognize problematic areas. The key to our CAD system is the segmentation of infrared video. The main challenges for segmenting infrared video compared to normal digital video are (1) as the foot warms up, it also warms up the surrounding, creating an ever changing contrast; and (2) there may be significant motion during imaging. To overcome this, a hybrid segmentation algorithm was developed based on a number of techniques such as continuous max-flow, model based segmentation, shape preservation, convex hull, and temperature normalization. Verifications of the automatic segmentation and registration using manual segmentation and markers show good agreement.

    Diabetic foot complications result from two broad pathologies-neuropathic and neuro-ischaemic feet. It is important for diabetic patients to have at least a yearly review of foot ulcer risk factors, and they should have a corresponding risk classification agreed based on this assessment. Diabetic foot ulcer assessment should include a wound classification tool, which can give an indication of wounds at greater risk of non-healing or amputation. The treatment of diabetic foot ulcers should be part of a comprehensive care plan that should also include treatment of infection, frequent debridement (if deemed appropriate by a skilled specialist clinician), biomechanical offloading, blood glucose control and treatment of comorbidities. Clinicians should base dressing selection on the wound's location, size and depth, amount of exudate, presence of infection or necrosis and the condition of the surrounding tissue.

    Foot size proportionate to stature is smaller in women than in men, and small feet apparently contribute to perceived physical attractiveness of females. This exploratory study investigated the sex difference in relative foot length and interrelations among foot length, physique, and foot preference ratings in samples from Austria and Canada, each comprised of 75 men and 75 women. The findings included the following lines of evidence: the sex difference in relative foot length replicated in both data sets; the magnitude of this sex effect was large. Relative foot length was smaller in young, nulliparous, and slim women. Pointed-toe and high-heel shoes were more likely worn by smaller, lighter, and slimmer women. Men reported liking women's feet in general more than vice versa. A vast majority of both men and women favored small feet in women, but large feet in men. One's own foot size appeared to correspond to evaluations of attractiveness; particularly, women with small feet preferred small feet in women in general. The preference for small feet in women was convergent across different methods of evaluating attractiveness. Directions for investigations in this emerging field of research on physical attractiveness are discussed.

    The diabetic foot is characterised by painless footulceration and/or arthropathy; it is a typical complicationof painless diabetic neuropathy. Neuropathy depletesthe foot skin of intraepidermal nerve fibre endings of theafferent A-delta and C-fibres, which are mostly nociceptorsand excitable by noxious stimuli only. However, someof them are cold or warm receptors whose functionsin diabetic neuropathy have frequently been reported.Hence, it is well established by quantitative sensory testingthat thermal detection thresholds at the foot skin increaseduring the course of painless diabetic neuropathy. Painperception (nociception), by contrast, has rarely beenstudied. Recent pilot studies of pinprick pain at plantardigital skinfolds showed that the perception thresholdwas always above the upper limit of measurement of 512mN (equivalent to 51.2 g) at the diabetic foot. However,deep pressure pain perception threshold at musculus abductor hallucis was beyond 1400 kPa (equivalent to 14 kg; limit of measurement) only in every fifth case. These discrepancies of pain perception between forefoot and hindfoot, and between skin and muscle, demand further study. Measuring nociception at the feet in diabetes opens promising clinical perspectives. A critical nociception threshold may be quantified (probably corresponding to a critical number of intraepidermal nerve fibre endings), beyond which the individual risk of a diabetic foot rises appreciably. Staging of diabetic neuropathy according to nociception thresholds at the feet is highly desirable as guidance to an individualised injury prevention strategy.

    Full Text Available In contrast to western countries, foot complaints are rare in Africa. This is remarkable, as many African adults walk many hours each day, often barefoot or with worn-out shoes. The reason why Africans can withstand such loading without developing foot complaints might be related to the way the foot is loaded. Therefore, static foot geometry and dynamic plantar pressure distribution of 77 adults from Malawi were compared to 77 adults from the Netherlands. None of the subjects had a history of foot complaints. The plantar pressure pattern as well as the Arch Index (AI and the trajectory of the center of pressure during the stance phase were calculated and compared between both groups. Standardized pictures were taken from the feet to assess the height of the Medial Longitudinal Arch (MLA. We found that Malawian adults: (1 loaded the midfoot for a longer and the forefoot for a shorter period during roll off, (2 had significantly lower plantar pressures under the heel and a part of the forefoot, and (3 had a larger AI and a lower MLA compared to the Dutch. These findings demonstrate that differences in static foot geometry, foot loading, and roll off technique exist between the two groups. The advantage of the foot loading pattern as shown by the Malawian group is that the plantar pressure is distributed more equally over the foot. This might prevent foot complaints.

    The uniquely designed limbs of the African elephant, Loxodonta africana, support the weight of the largest terrestrial animal. Besides other morphological peculiarities, the feet are equipped with large subcutaneous cushions which play an important role in distributing forces during weight bearing and in storing or absorbing mechanical forces. Although the cushions have been discussed in the literature and captive elephants, in particular, are frequently affected by foot disorders, precise morphological data are sparse. The cushions in the feet of African elephants were examined by means of standard anatomical and histological techniques, computed tomography (CT) and magnetic resonance imaging (MRI). In both the forelimb and the hindlimb a 6th ray, the prepollex or prehallux, is present. These cartilaginous rods support the metacarpal or metatarsal compartment of the cushions. None of the rays touches the ground directly. The cushions consist of sheets or strands of fibrous connective tissue forming larger metacarpal/metatarsal and digital compartments and smaller chambers which were filled with adipose tissue. The compartments are situated between tarsal, metatarsal, metacarpal bones, proximal phalanges or other structures of the locomotor apparatus covering the bones palmarly/plantarly and the thick sole skin. Within the cushions, collagen, reticulin and elastic fibres are found. In the main parts, vascular supply is good and numerous nerves course within the entire cushion. Vater-Pacinian corpuscles are embedded within the collagenous tissue of the cushions and within the dermis. Meissner corpuscles are found in the dermal papillae of the foot skin. The micromorphology of elephant feet cushions resembles that of digital cushions in cattle or of the foot pads in humans but not that of digital cushions in horses. Besides their important mechanical properties, foot cushions in elephants seem to be very sensitive structures.

    Full Text Available Foot problems are a major cause of morbidity and mortality in elephants, but are underreported due to difficulties in diagnosis, particularly of conditions affecting the bones and internal structures. Here we evaluate post-mortem computer tomographic (CT scans of 52 feet from 21 elephants (seven African Loxodonta africana and 14 Asian Elephas maximus, describing both pathology and variant anatomy (including the appearance of phalangeal and sesamoid bones that could be mistaken for disease. We found all the elephants in our study to have pathology of some type in at least one foot. The most common pathological changes observed were bone remodelling, enthesopathy, osseous cyst-like lesions, and osteoarthritis, with soft tissue mineralisation, osteitis, infectious osteoarthriti, subluxation, fracture and enostoses observed less frequently. Most feet had multiple categories of pathological change (81% with two or more diagnoses, versus 10% with a single diagnosis, and 9% without significant pathology. Much of the pathological change was focused over the middle/lateral digits, which bear most weight and experience high peak pressures during walking. We found remodelling and osteoarthritis to be correlated with increasing age, more enthesopathy in Asian elephants, and more cyst-like lesions in females. We also observed multipartite, missing and misshapen phalanges as common and apparently incidental findings. The proximal (paired sesamoids can appear fused or absent, and the predigits (radial/tibial sesamoids can be variably ossified, though are significantly more ossified in Asian elephants. Our study reinforces the need for regular examination and radiography of elephant feet to monitor for pathology and as a tool for improving welfare.

    BACKGROUND: Myths prevailing about diabetes in the society have become a major hurdle for its proper treatment and control. AIM: To find out about various myths related to diabetes and its treatment in the population. MATERIALS AND METHODS: A cross sectional study was carried out in a teaching hospital of Delhi in 2008. 124 diabetic patients attending the regular diabetic clinic, 78 people who accompanied these patients and 214 non-diabetic people were included in the study. A pre-tested interview schedule with 48 questions was used to get information about sociodemographic characteristics and myths about diabetes. Data was analyzed by Epi info software version 3.2. RESULTS: The most common myth in the population (22%) was that eating more sugar causes diabetes. Others were: diabetes can only occur in old age, soaking feet in water can help control blood sugar, diabetes is a result of past sins and is cured by spiritual treatment. Myths were significantly more common in females, non-diabetics, less educated group. There was a slightly higher prevalence of myths in Muslim population. 12.1% of diabetics were taking herbal medicines. 15.9% of the diabetics and 26% of non diabetics were unaware that complications could occur if diabetes was uncontrolled. 18.5% of diabetics and 30.1% of non-diabetics were unaware about role of diet and lifestyle measures in control of diabetes. CONCLUSIONS: The prevalence of myths about diabetes is high in North Indian population which could be associated with poor early health seeking behavior and poor compliance with treatment.

    Full Text Available The aim of this study was to determine the possible relationship between loss of thenormal medial longitudinal arch measured by the height of the navicular bone in a static situationand variables related to plantar pressure distribution measured in a dynamic situation. Elevenmen (21 ± 3 years, 74 ± 10 kg and 175 ± 4 cm participated in the study. The Novel Emed-ATSystem was used for the acquisition of plantar pressure distribution data (peak pressure, meanpressure, contact area, and relative load at a sampling rate of 50 Hz. The navicular drop testproposed by Brody (1982 was used to assess the height of the navicular bone for classificationof the subjects. The results were compared by the Mann-Whitney U test, with the level of significanceset at p ≤ 0.05. Differences were observed between the two groups in the mid-foot regionfor all variables studied, with the observation of higher mean values in subjects with flat feet.There were also significant differences in contact area, relative load, peak pressure, and meanpressure between groups. The present study demonstrates the importance of paying attentionto subjects with flat feet because changes in plantar pressure distribution are associated withdiscomfort and injuries.

    Objectives Lengthening osteotomies of the calcaneus in children are in general grafted with bone from the iliac crest. Artificial bone grafts have been introduced, however, their structural and clinical durability has not been documented. Radiostereometric analysis (RSA) is a very accurate and precise method for measurements of rigid body movements including the evaluation of joint implant and fracture stability, however, RSA has not previously been used in clinical studies of calcaneal osteotomies. We assessed the precision of RSA as a measurement tool in a lateral calcaneal lengthening osteotomy (LCLO). Methods LCLO was performed in six fixed adult cadaver feet. Tantalum markers were inserted on each side of the osteotomy and in the cuboideum. Lengthening was done with a plexiglas wedge. A total of 24 radiological double examinations were obtained. Two feet were excluded due to loose and poorly dispersed markers. Precision was assessed as systematic bias and 95% repeatability limits. Results Systematic bias was generally below 0.10 mm for translations. Precision of migration measurements was below 0.2 mm for translations in the osteotomy. Conclusion RSA is a precise tool for the evaluation of stability in LCLO. Cite this article: Bone Joint Res 2015;4:78–83. PMID:25957380

    Full Text Available Introduction Foot orthosis is used as protective treatment in people with flatfoot. This study aimed at assessing the effects of Foot orthosis on energy consumption in 20 runners with flat feet.Methods: In this study a treadmill and a Quark b2 were used to measure oxygen consumption. For each patient, a pair of foot orthosis with the appropriate size was prepared. The maximum running Heart rate, vo2 max and vo2 of the subjects were measured and calculated with and without foot orthoses. The data were compared through paired T-test.Results: In this study, after using the foot orthoses, the mean VO2 (ML/M, theVO2 max (ML/M for each Kg of body weight and the maximum heart rate respectively reduced from 4504.6 to 4488.3, from 63.6 to 63.4 and from 168.7 to 168.0, all of which indicating a significant observed reduction (P<0.05.Conclusion: Foot support devices (orthoses result in realignment of lower extremity joints in patients with flat feet, thus length- tension relationship of muscles improve. This prevents muscle fatigue in long- distance running. Finally, when suitable foot orthoses was applied energy consumption during running decreased.

    Marine organisms secrete adhesives for substrate attachment that to be effective require functional assembly underwater and displacement of water, ions, and weakly bound polyions that are ubiquitous in seawater. Therefore, understanding the characteristics of these protein/carbohydrate-based marine adhesives is imperative to decipher marine adhesion and also, to accelerate the development of new biomimetic underwater adhesives and anti-fouling agents. The present study, aims at mapping the proteome of the sea urchin Paracentrotus lividus adhesive organs using a combination of complementary protein separation techniques (1-D-nanoLC and 2-DE), databases and search algorithms. This strategy resulted in the identification of 328 non-redundant proteins, constituting the first comprehensive list of sea urchin tube feet proteins. Given the known importance of phosphorylation and glycosylation in marine adhesion, the 2DE proteome was re-analyzed with specific fluorescent stains for these two PTMs, resulting in the identification of 69 non-redundant proteins. The obtained results demonstrate that tube feet are unique mechano-sensory adhesive organs and highlight putative adhesive proteins, that although requiring further confirmation, constitute a step forward in the quest to decipher sea urchins temporary adhesion.

    Birds display remarkable diversity in the distribution and morphology of scales and feathers on their feet, yet the genetic and developmental mechanisms governing this diversity remain unknown. Domestic pigeons have striking variation in foot feathering within a single species, providing a tractable model to investigate the molecular basis of skin appendage differences. We found that feathered feet in pigeons result from a partial transformation from hindlimb to forelimb identity mediated by cis-regulatory changes in the genes encoding the hindlimb-specific transcription factor Pitx1 and forelimb-specific transcription factor Tbx5. We also found that ectopic expression of Tbx5 is associated with foot feathers in chickens, suggesting similar molecular pathways underlie phenotypic convergence between these two species. These results show how changes in expression of regional patterning genes can generate localized changes in organ fate and morphology, and provide viable molecular mechanisms for diversity in hindlimb scale and feather distribution.

    Functional integration is an inherent characteristic for multiscale structures of biological materials. In this contribution, we first investigate the liquid-solid adhesive forces between water droplets and superhydrophobic gecko feet using a high-sensitivity micro-electromechanical balance system. It was found, in addition to the well-known solid-solid adhesion, the gecko foot, with a multiscale structure, possesses both superhydrophobic functionality and a high adhesive force towards water. The origin of the high adhesive forces of gecko feet to water could be attributed to the high density nanopillars that contact the water. Inspired by this, polyimide films with gecko-like multiscale structures were constructed by using anodic aluminum oxide templates, exhibiting superhydrophobicity and a strong adhesive force towards water. The static water contact angle is larger than 150° and the adhesive force to water is about 66 μN. The resultant gecko-inspired polyimide film can be used as a ``mechanical hand'' to snatch micro-liter liquids. We expect this work will provide the inspiration to reveal the mechanism of the high-adhesive superhydrophobic of geckos and extend the practical applications of polyimide materials.

    Foot problems are extremely common in elephants and radiography is the only imaging method available but the radiographic anatomy has not been described in detail. The aims of this study were to develop a radiographic protocol for elephant feet using digital radiography, and to describe the normal radiographic anatomy of the Asian elephant front and hind foot. A total of fifteen cadaver foot specimens from captive Asian elephants were radiographed using a range of projections and exposures to determine the best radiographic technique. This was subsequently tested in live elephants in a free-contact setting. The normal radiographic anatomy of the Asian elephant front and hind foot was described with the use of three-dimensional models based on CT reconstructions. The projection angles that were found to be most useful were 65-70° for the front limb and 55-60° in the hind limb. The beam was centred 10-15 cm proximal to the cuticle in the front and 10-15 cm dorsal to the plantar edge of the sole in the hind foot depending on the size of the foot. The protocol developed can be used for larger-scale diagnostic investigations of captive elephant foot disorders, while the normal radiographic anatomy described can improve the diagnostic reliability of elephant feet radiography.

    Tissue engineered biomaterials have biodegradable and biocompatible properties. In this study, we have fabricated sponges using duck's feet derived collagen (DC) and gellan gum (GG), and further studied its inflammatory responses. The as-prepared duck's feet DC/GG sponges showed the possibility of application as a tissue engineering material through in vitro and in vivo experiments. The physical and chemical properties of sponges were characterized by compression strength, porosity, and scanning electron microscopy, etc. In vitro cell viability were investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assay. An inflammatory response was studied after seeding RAW264.7 cells on as-fabricated sponges using reverse transcriptase-polymerase chain reaction. In vivo studies were carried out by implanting in subcutaneous nude mouse followed by extraction, histological staining. Collectively, superior results were showed by DC/GG sponges than GG sponge in terms of physical property and cell proliferation and thus can be considered as a potential candidate for future tissue engineering applications.

    The Fernald Site, a Department of Energy (DOE) uranium metal production facility that ceased production in 1989, is now being remediated by the DOE under terms of a Consent Agreement with the United States Environmental Protection Agency (USEPA) and a Consent Decree with the State of Ohio. It is estimated that the cleanup will generate 104,000,000 cubic feet of low-level radioactive waste including construction debris, pit sludge, radium residue and a huge volume of uranium contaminated soil. The waste handling strategy for this huge volume of waste includes minimizing remedial waste generation, recycling material when economically feasible, free-releasing clean material and volume reduction. It is anticipated that large scale radium residue vitrification and sludge drying equipment/facilities will be constructed onsite for waste treatment prior to off-site disposal. Fernald waste disposition will include both onsite disposal (if approved under CERCLA) and off-site disposal at both commercial and DOE waste disposal facilities. The waste disposition strategy selected reflects a diverse variety of technical, political, regulatory and economic factors.

    Although knee motions have been observed at loss of balance, the ankle and hip strategies have remained the focus of past research. The present study aimed to investigate whether knee motions contribute to feet-in-place balance recovery. This was achieved by experimentally monitoring knee motions during recovery from forward falling, and by simulating balance recovery movements with and without knee joint as the main focus of the study. Twelve participants initially held a straight body configuration and were released from different forward leaning positions. Considerable knee motions were observed especially at greater leaning angles. Simulations were performed using 3-segment (feet, shanks+thighs, and head+arms+trunk) and 4-segment (with separate shanks and thighs segments) planar models. Movements were driven by joint torque generators depending on joint angle, angular velocity, and activation level. Optimal joint motions moved the mass center projection to be within the base of support without excessive joint motion. The 3-segment model (without knee motions) generated greater backward linear momentum and had better balance performance, which confirmed the advantage of having only ankle/hip strategies. Knee motions were accompanied with less body angular momentum and a lower body posture, which could be beneficial for posture control and reducing falling impact, respectively.

    Full Text Available Aimed at solving the misplaced body trajectory problem caused by the rolling of semi-round rigid feet when a robot is walking, a legged kinematic trajectory correction methodology based on the Least Squares Support Vector Machine (LS-SVM is proposed. The concept of ideal foothold is put forward for the three-dimensional kinematic model modification of a robot leg, and the deviation value between the ideal foothold and real foothold is analyzed. The forward/inverse kinematic solutions between the ideal foothold and joint angular vectors are formulated and the problem of direct/inverse kinematic nonlinear mapping is solved by using the LS-SVM. Compared with the previous approximation method, this correction methodology has better accuracy and faster calculation speed with regards to inverse kinematics solutions. Experiments on a leg platform and a hexapod walking robot are conducted with multi-sensors for the analysis of foot tip trajectory, base joint vibration, contact force impact, direction deviation, and power consumption, respectively. The comparative analysis shows that the trajectory correction methodology can effectively correct the joint trajectory, thus eliminating the contact force influence of semi-round rigid feet, significantly improving the locomotion of the walking robot and reducing the total power consumption of the system.

The purpose of the present study was (i to investigate the association between fluid intake and a potential development of peripheral oedemas leading to an increase of the feet volume in 100-km ultra-marathoners and (ii to evaluate a possible association between the changes in plasma sodium concentration ([Na+] and changes in feet volume. Methods In seventy-six 100-km ultra-marathoners, body mass, plasma [Na+], haematocrit and urine specific gravity were determined pre- and post-race. Fluid intake and the changes of volume of the feet were measured where the changes of volume of the feet were estimated using plethysmography. Results Body mass decreased by 1.8 kg (2.4% (p +] increased by 1.2% (p p = 0.0005. The volume of the feet remained unchanged (p > 0.05. Plasma volume and urine specific gravity increased (p r = 0.54, p +] (r = -0.28, p = 0.0142. Running speed was negatively related to both fluid intake (r = -0.33, p = 0.0036 and the change in feet volume (r = -0.23, p = 0.0236. The change in the volume of the feet was negatively related to the change in plasma [Na+] (r = -0.26, p = 0.0227. The change in body mass was negatively related to both post-race plasma [Na+] (r = -0.28, p = 0.0129 and running speed (r = -0.34, p = 0.0028. Conclusions An increase in feet volume after a 100-km ultra-marathon was due to an increased fluid intake.

    Currently there are over 740,000 patients with diabetes mellitus in the Netherlands, and this number will increase further in the coming years. Approximately 90% of patients has type 2 diabetes, a metabolic disorder that is often associated with obesity, hypertension and increased cholesterol levels. Treatment of diabetes mellitus is essential to reduce the risk of severe complications with irreversible organ damage in the long-term. Gingivitis and periodontitis are more common in patients with diabetes mellitus and are now also considered as complications of diabetes. Collaboration among healthcare professionals is important for effective diabetes care.

    The manifestations of systemic lupus erythematosus (SLE) vary between individuals, from the severe and life-threatening renal and central nervous system involvement, to the involvement of skin, musculoskeletal and vascular system, and the complications of infection influencing the quality of life. However, as specific manifestations affecting the lower limb are perceived as receiving little focus, the purpose of this narrative literature review is to identify the specific factors associated with SLE that may have implications for lower limb and foot morbidity. A structured search of databases was conducted. The inclusion was restricted to publications in the English language, those that specifically investigate the feet as affected with SLE. No restriction on year of publication was imposed to reduce publication bias and to capture as many publication in relation to feet. Eleven papers fulfilled the inclusion criteria. There were seven additional papers that made observations related to the articular or vascular complications of the feet. This narrative review provides some information on how SLE affects the lower limb and foot in relation to the musculoskeletal and vascular systems. However, there is a lack of literature that specifically focuses on all the manifestations of SLE and the complications associated with its management. There are indications that SLE affects lower limb and foot morbidity but the scale of these problems is unclear and this is partly because of the absence of research and the lack of a 'gold standard' framework for the assessment of the lower limb and foot. In addition to clinical foot health assessment, ultrasonography may be a useful alternative to plain film radiography or magnetic resonance imaging (MRI) in capturing the extent of articular and extra-articular manifestations. Further, the Ankle Brachial Pressure Index (ABPI) may be useful in identifying those with atherosclerosis and ischaemia. There are indications that SLE affects

    Solar prominences are clouds of cool plasma levitating above the solar surface and insulated from the million-degree corona by magnetic fields. They form in regions of complex magnetic topology, characterized by non-potential fields, which can evolve abruptly, disintegrating the prominence and ejecting magnetized material into the heliosphere. However, their physics is not yet fully understood because mapping such complex magnetic configurations and their evolution is extremely challenging, and must often be guessed by proxy from photometric observations. Using state-of-the-art spectro-polarimetric data, we reconstruct the structure of the magnetic field in a prominence. We find that prominence feet harbor helical magnetic fields connecting the prominence to the solar surface below.

    Peri-mortem limb amputations are rarely reported in the paleopathological literature. The cases reported here concern severing of both hands and feet observed in three adult male skeletons, exhumed from the medieval Portuguese necropolis of Rossio do Marquês de Pombal, Estremoz, Portugal. The fact that they were found in the same site, in graves placed side by side, that all are young males, and that the three skeletons show similar perimortem injuries, make this a unique case meriting detailed analysis. Considering the lesions' location and pattern, as well as historical data, we hypothesize that this is a case of amputation as a consequence of judicial punishment. Estremoz was an important city in sustaining the Royal power at a regional scale during the medieval period. Copyright © 2017 Elsevier Inc. All rights reserved.

    Objective To study the preliminary pathogenesis of dawn phenomenon in patients with type 2 diabetes mellitus. Methods Two-hundred and sixty-four patients with type 2 diabetes had performed continuous glucose monitoring since Jan 2012 to July 2014. They were divided into two groups: patients without dawn phenomenon and patients with dawn phenomenon. Biochemical indicators including liver and kidney function, blood lipids, HbA1C , fructosamine(FMN), adrenocorticotropic hormone and cortisol were detected in the two groups. Oral glucose tolerance test, insulin releasing test and glucagon releasing test were performed. The differences in biochemical indicators, glucose level and α-cell and β-cell function after fasting and glucose-load were compared. The correlation and regression analysis were performed between dawn phenomenon and other indicators. Results The level of adrenocorticotropic hormone, cortisol, HbA1C , FMN, the increment of fasting glucose and nocturnal nadir glucose (BG1 ), the glucose increment before and after breakfast(BG2 ), 24-hour mean glucose, duration above high limit, and HOMA-IR were significantly higher in patients with dawn phenomenon compared to those in patients without dawn phenomenon[(6. 6 ± 2. 4) vs(4. 8 ± 1. 9) pmol/ L, (523. 8 ± 84. 2) vs (448. 2 ± 76. 9) nmol/ L, (8. 1 ± 2. 0)% vs (7. 5 ± 1. 8)% ,(0. 32 ± 0. 09) vs(0. 29 ± 0. 08) mmol/ L, (26. 2 ± 5. 8) vs (18. 0 ± 4. 9) mg/ dl, (39. 6 ± 8. 3) vs (28. 8 ± 7. 4) mg/ dl,(188. 5 ± 36. 2) vs(164. 5 ± 31. 2) mg/ dl, 29 : 31(41% ) vs 20 : 10(28% ), 4. 18 ± 0. 94 vs 3. 82 ± 0. 82](all P<0. 05).

    Full Text Available Abstract Background Footwear characteristics have been implicated in fatigue and foot pain. The recommended time for changing running shoes is every 500 miles. The aim of our study was to assess and compare plantar peak pressures and pressure time integrals in new and old running shoes. Findings This was a prospective study involving 11 healthy female volunteers with no previous foot and ankle problems. New running shoes were provided to the participants. Plantar pressures were measured using the Novel Pedar system while walking with new and participants' personal old running shoes. Plantar pressures were measured in nine areas of the feet. Demographic data, age of old running shoes, Body Mass Index (BMI, peak pressures and pressure-time integral were acquired. The right and left feet were selected at random and assessed separately. Statistical analysis was done using the paired t test to compare measurements between old and new running shoes. The mean peak pressures were higher in new running shoes (330.5 ± 79.6 kiloPascals kPa when compared to used old running shoes (304 ± 58.1 kPa (p = 0.01. The pressure-time integral was significantly higher in the new running shoes (110 ± 28.3 kPa s compared to used old running shoes (100.7 ± 24.0 kPa s (p = 0.01. Conclusion Plantar pressure measurements in general were higher in new running shoes. This could be due to the lack of flexibility in new running shoes. The risk of injury to the foot and ankle would appear to be higher if running shoes are changed frequently. We recommend breaking into new running shoes slowly using them for mild physical activity.

    Adhesive pads should reduce the action of the local muscle contraction on the skin leading to a decrease in the depth of existing wrinkles and the formation of new dynamic wrinkles. This study aims at assessing the antiwrinkles action of adhesive pads during time, and the temporary improvement of facial skin appearance by reducing the vision of linear wrinkles and improving skin elasticity. Thirty-nine subjects participated to a placebo-controlled study. In the short-term test, the measurements were taken 15, 30, and 60 minutes following 30 minutes application of the product; in the long-term test, the measurements were taken after wearing pads every night for 4 weeks. The roughness parameter of the skin surface was calculated by using a profilometry software 3D MEX(®) . In the short- and long-term tests, analyzing the average of the elastomeric measurements, no significant change was observed in any of the parameters analyzed after 15, 30, and 60 minutes. The adhesive pad decreased significantly all roughness skin parameters 15 minutes after short-term application and until 60 minutes after long-term application. These changes did not occur in the contralateral untreated zone. The use of topical adhesive pads improves wrinkles in the crow's feet area in the first hour after use. However, patient self-evaluation indicated that the use of topical adhesive pads for 3 weeks may offer subjective improvement in crow's feet zone over a 2 hour period. Topical adhesive pads are safe to use and tolerable for most users. © 2017 Wiley Periodicals, Inc.

    Full Text Available Objectives : The aim was to assess of the morphology, intensity, and activity of changes in the first ultrasonographic (US examination of hands and feet in patients with early arthritis (lasting up to 12 months who were ultimately diagnosed with rheumatoid arthritis (RA. An attempt was made to demonstrate a correlation between the intensity of lesions in US and selected laboratory parameters. Material and methods : Ultrasonographic examination was performed using a LOGIC GE 500 device on a group of 60 patients with arthritis (46 women, 14 men aged 18–80, previously untreated. In total, 3120 hand and feet joints were examined. The assessment focused on the presence of joint effusion, synovial proliferation and power Doppler signals (assessed on a semi-quantitative scale. Each patient underwent laboratory tests, necessary for making a diagnosis. In order to analyze the correlations between changes in US and laboratory parameters, erythrocyte sedimentation rate (ESR, reactive protein test (CRP, rheumatoid factor (RF, and anti-citrullinated protein antibodies (ACPAs were used. Results : In the study group, the average duration of arthritis symptoms until the first US examination was 5.6 months. Among the 3120 examined hand and foot joints, deviations from the norm appeared in 1093 joints, synovial hypertrophy was found in 471 joints (grade 1 synovial hypertrophy was reported most frequently, while presence of signal in Power Doppler was revealed in 261 joints (grade 1 was observed most frequently. A statistically significant correlation was found between the intensity of changes in Power Doppler and CRP concentration. Conclusions : In patients with increased concentrations of CRP, we may expect arthritis of higher intensity, therefore, in order to prevent the progression of destructive changes, it is necessary to quickly implement effective disease-modifying antirheumatic treatment. The conducted research showed that the activity of joint

    The energy storing and releasing behaviour of 2 energy storing feet (ESF) and 2 conventional prosthetic feet (CF) were compared (ESF: Otto Bock Dynamic Pro and Hanger Quantum; CF: Otto Bock Multi Axial and Otto Bock Lager). Ten trans-tibial amputees were selected. The study was designed as a double-blind, randomised trial. For gait analysis a VICON motion analysis system was used with 2 AMTI force platforms. A special measuring device was used for measuring energy storage and release of the foot during a simulated step. The impulses of the anteroposterior component of the ground force showed small, statistically non-significant differences (deceleration phase: 22.7-23.4 Ns; acceleration phase: 17.0-18.4 Ns). The power storage and release phases as well as the net results also showed small differences (maximum difference in net result is 0.03 J kg-1). It was estimated that these differences lead to a maximum saving of 3% of metabolic energy during walking. It was considered unlikely that the subjects would notice this difference. It was concluded that during walking differences in mechanical energy expenditure of this magnitude are probably not of clinical relevance. Ankle power, as an indicator for energy storage and release gave different results to the energy storage and release as measured with the special test device, especially during landing response. In the biomechanical model (based on inverse dynamics) used in the gait analysis the deformation of the material is not taken into consideration and hence this method of gait analysis is probably not suitable for calculation of shock absorption.

    Diabetes mellitus is a common condition and diabetics are prone to develop a spectrum of neuropathic complications ranging from symmetric and diffuse to asymmetric and focal neuropathies that may be associated with significant morbidity. Diabetic sensorimotor polyneuropathy is the most common of these complications, occurring in patients with type 1 and 2 diabetes mellitus, as well as in those with prediabetes and glucose intolerance. In this review, the authors discuss the wide variety of neuropathies that can present in the context of diabetes, including the clinical manifestations, diagnostic features, and approach to management.

    The aim of this study was to investigate the role of foot morphology, related with respect to diabetes and peripheral neuropathy in altering foot kinematics and plantar pressure during gait. Healthy and diabetic subjects with or without neuropathy with different foot types were analyzed. Three dimensional multisegment foot kinematics and plantar pressures were assessed on 120 feet: 40 feet (24 cavus, 20 with valgus heel and 11 with hallux valgus) in the control group, 80 feet in the diabetic (25 cavus 13 with valgus heel and 13 with hallux valgus) and the neuropathic groups (28 cavus, 24 with valgus heel and 18 with hallux valgus). Subjects were classified according to their foot morphology allowing further comparisons among the subgroups with the same foot morphology. When comparing neuropathic subjects with cavus foot, valgus heel with controls with the same foot morphology, important differences were noticed: increased dorsiflexion and peak plantar pressure on the forefoot (Pfoot morphology in altering both kinematics and plantar pressure in diabetic subjects, diabetes appeared to further contribute in altering foot biomechanics. Surprisingly, all the diabetic subjects with normal foot arch or with valgus hallux were no more likely to display significant differences in biomechanics parameters than controls. This data could be considered a valuable support for future research on diabetic foot function, and in planning preventive interventions.

    Most people with diabetes suffer some deterioration of the feet. Diabetic foot syndrome causes ulceration in about 15% of cases and such deterioration leads to amputation in about 2.5% of diabetic patients, diminishing their quality of life and generating extraordinary costs for patients and public health systems. Currently, there is no objective method for the detection of diabetic foot syndrome in its early stages. We propose terahertz imaging as a method for the evaluation of such deterioration. This screening method could aid the prevention and medical treatment of this condition in the future. PMID:28165050

In the present study, we investigated the accuracy of this system for the diagnosis of diabetes mellitus in Chinese. Methods We performed the EZSCAN test in diabetic and non-diabetic subjects. EZSCAN measures electrochemical conductance (EC at forehead, hands and feet, and derives a diabetes index with a value ranging from 0 to 100. Diabetes mellitus was defined as a plasma glucose concentration of at least 7 mmol/l at fasting or 11.1 mmol/l at 2 hours after glucose load, or as the use of antidiabetic drugs. Results The 195 study participants (51% men, mean age 52 years included 75 diabetic patients (use of antidiabetic drugs 81% and 120 non-diabetic subjects. EC (micro Siemens, μSi was significantly (P P = 0.39. When a diabetes index of 40 (suggested by the manufacturer was used as the threshold, the sensitivity and specificity for the diagnosis of diabetes mellitus was 85% and 64%, respectively.

    Elastic-plastic, large-deflection nonlinear stress analyses are performed for the external hat-shaped stringers (or stiffeners) on the intertank portion of the Space Shuttle s external tank. These stringers are subjected to assembly strains when the stringers are initially installed on an intertank panel. Four different stringer-feet configurations including the baseline flat-feet, the heels-up, the diving-board, and the toes-up configurations are considered. The assembly procedure is analytically simulated for each of these stringer configurations. The location, size, and amplitude of the strain field associated with the stringer assembly are sensitive to the assumed geometry and assembly procedure. The von Mises stress distributions from these simulations indicate that localized plasticity will develop around the first eight fasteners for each stringer-feet configuration examined. However, only the toes-up configuration resulted in high assembly hoop strains.

  7. The effect that energy storage and return feet have on the propulsion of the body: a pilot study.

    2014-09-01

    A variety of energy storage and return prosthetic feet are currently available for use within lower limb prostheses. Designs claim to provide a beneficial energy return during push-off, but the extent to which this occurs remains disputed. Techniques currently used to measure energy storage, dissipation and return within the structure of the prosthetic foot are debatable, with limited evidence to support substantial elastic energy storage and return from existing designs. The aim of this study was to evaluate the performance of energy storage and return foot designs through considering the ankle power during push-off and the effect on body centre of mass propulsion. To achieve this aim, the gait patterns of six trans-tibial prosthetic users wearing different designs of energy storage and return feet were analysed while ascending a ramp. Three examples of energy storage and return feet (suitable for moderate activity) were selected and randomly evaluated: the Blatchford's Epirus, Össur Assure and College Park Tribute feet. The power at the anatomical and mechanical ankle joints was integrated to evaluate the work done over the gait cycle. The direction of the inertial force, and therefore propulsion of the body centre of mass, was used to indicate the effect of the energy return by the energy storage and return feet. Results indicate that although energy storage and return feet may provide energy return, the work done around the prosthetic ankle indicates net power absorption. Therefore, the prosthetic limb is unable to contribute to the body centre of mass propulsion to the same extent as the biological limb.

  8. Classification of forefoot plantar pressure distribution in persons with diabetes: a novel perspective for the mechanical management of diabetic foot?

    Directory of Open Access Journals (Sweden)

    Kevin Deschamps

    Full Text Available BACKGROUND: The aim of this study was to identify groups of subjects with similar patterns of forefoot loading and verify if specific groups of patients with diabetes could be isolated from non-diabetics. METHODOLOGY/PRINCIPAL FINDINGS: Ninety-seven patients with diabetes and 33 control participants between 45 and 70 years were prospectively recruited in two Belgian Diabetic Foot Clinics. Barefoot plantar pressure measurements were recorded and subsequently analysed using a semi-automatic total mapping technique. Kmeans cluster analysis was applied on relative regional impulses of six forefoot segments in order to pursue a classification for the control group separately, the diabetic group separately and both groups together. Cluster analysis led to identification of three distinct groups when considering only the control group. For the diabetic group, and the computation considering both groups together, four distinct groups were isolated. Compared to the cluster analysis of the control group an additional forefoot loading pattern was identified. This group comprised diabetic feet only. The relevance of the reported clusters was supported by ANOVA statistics indicating significant differences between different regions of interest and different clusters. CONCLUSION/S SIGNIFICANCE: There seems to emerge a new era in diabetic foot medicine which embraces the classification of diabetic patients according to their biomechanical profile. Classification of the plantar pressure distribution has the potential to provide a means to determine mechanical interventions for the prevention and/or treatment of the diabetic foot.

    Background Berberine is an isoquinoline alkaloid widely used to improve the glucidic and lipidic profiles of patients with hypercholesterolemia, metabolic syndrome, and type 2 diabetes. The limitation of berberine seems to be its poor oral bioavailability, which is affected by the presence, in enterocytes, of P-glycoprotein – an active adenosine triphosphate (ATP)-consuming efflux protein that extrudes berberine into the intestinal lumen, thus limiting its absorption. According to some authors, silymarin, derived from Silybum marianum, could be considered a P-glycoprotein antagonist. Aim The study aimed to evaluate the role played by a possible P-glycoprotein antagonist (silymarin), when added to a product containing Berberis aristata extract, in terms of benefits to patients with type 2 diabetes. Methods The study enrolled 69 patients with type 2 diabetes in suboptimal glycemic control who were treated with diet, hypoglycemic drugs, and in cases of concomitant alterations of the lipid profile, hypolipidemic agents. The patients received an add-on therapy consisting of either a standardized extract of Berberis aristata (titrated in 85% berberine) corresponding to 1,000 mg/day of berberine, or Berberol®, a fixed combination containing the same standardized extract of Berberis aristata plus a standardized extract of Silybum marianum (titrated as >60% in silymarin), for a total intake of 1,000 mg/day of berberine and 210 mg/day of silymarin. Results Both treatments similarly improved fasting glucose, total cholesterol, low-density lipoprotein (LDL) cholesterol, triglyceride, and liver enzyme levels, whereas glycosylated hemoglobin (HbA1c) values were reduced to a greater extent by the fixed combination. Conclusion The association of berberine and silymarin demonstrated to be more effective than berberine alone in reducing HbA1c, when administered at the same dose and in the form of standardized extracts in type 2 diabetic patients.

    Diabetic neuropathy is most common chronic complication of diabetes mellitus. It is responsible for substantial morbidity, increased mortality and impaired quality of life. Patogenesis of diabetic neuropathy is complex. Chronic hyperglycemia is a major factor induces nerve fibers injury. High level of glucose stimulate the polyol pathway causing osmotic stress and enhance reactive oxygen species generation, as well as it play an important role in diabetic angiopathy development. Distal symmetric polineuropathy is most common type of diabetic neuropathy. Many patient may develop combinations of neuropathies concerning somatic and autonomic system.

    Indian Navy divers carried out no-decompression dives at altitudes of 7000 to 14,200 ft (2134-4328 m) in the Nilgiris and Himalayas from May to July 1988. Seventy-eight dives on air and 22 dives on oxygen were carried out at various altitudes. The final dives were at Lake Pangong Tso (4328 m) in Ladakh, Himalayas, to a maximum of 140 feet of sea water (fsw) [42.6 meters of sea water (msw)] equivalent ocean depth in minimum water temperature of 2 degrees C. Oxygen diving at 14,200 ft (4328 m) was not successful. Aspects considered were altitude adaptation, diminished air pressure diving, hypothermia, and remote area survival. Depths at altitude were converted to depths at sea level and were applied to the Royal Navy air tables. Altitude-related manifestations, hypoxia, hypothermia, suspected oxygen toxicity, and equipment failure were observed. It is concluded that stress is due to effects of altitude and cold on man and equipment, as well as changes in diving procedures when diving at high altitudes. Equivalent air depths when applied to Royal Navy tables could be considered a safe method for diving at altitudes.

  14. System overview and walking dynamics of a passive dynamic walking robot with flat feet

    Full Text Available The concept of “passive dynamic walking robot” refers to the robot that can walk down a shallow slope stably without any actuation and control which shows a limit cycle during walking. By adding actuation at some joints, the passive dynamic walking robot can walk stably on level ground and exhibit more versatile gaits than fully passive robot, namely, the “limit cycle walker.” In this article, we present the mechanical structures and control system design for a passive dynamic walking robot with series elastic actuators at hip joint and ankle joints. We built a walking model that consisted of an upper body, knee joints, and flat feet and derived its walking dynamics that involve double stance phases in a walking cycle based on virtual power principle. The instant just before impact was chosen as the start of one step to reduce the number of independent state variables. A numerical simulation was implemented by using MATLAB, in which the proposed passive dynamic walking model could walk stably down a shallow slope, which proves that the derived walking dynamics are correct. A physical passive robot prototype was built finally, and the experiment results show that by only simple control scheme the passive dynamic robot could walk stably on level ground.

    [Purpose] This study investigated the relationship between toe grip strength and foot posture in children. [Subjects and Methods] A total of 619 children participated in this study. The foot posture of the participants was measured using a foot printer and toe grip strength was measured using a toe grip dynamometer. Children were classified into 3 groups; flatfoot, normal, and high arch, according to Staheli’s arch index. The differences in demographic data and toe grip strength among each foot posture group were analyzed by analysis of variance. Additionally, toe grip strength differences were analyzed by analysis of covariance, adjusted to body mass index, age, and gender. [Results] The number of participants classified as flatfoot, normal, and high arch were 110 (17.8%), 468 (75.6%), and 41 (6.6%), respectively. The toe grip strength of flatfoot children was significantly lower than in normal children, as shown by both analysis of variance and analysis of covariance. [Conclusion] A significant difference was detected in toe grip strength between the low arch and normal foot groups. Therefore, it is suggested that training to increase toe grip strength during childhood may prevent the formation of flat feet or help in the development of arch. PMID:26696732

    Full Text Available Postcolonial writers like Salman Rushdie often write back to the “empire” by appropriating myth and allegory. In The Ground beneath Her Feet, Rushdie rewrites the mythological story of Orpheus and Eurydice, using katabasis (the trope of the descent into Hell to comment both on the situation of the postcolonial writer from a personal perspective and to attempt a redefinition of postcolonial migrant identity-formation. Hell has a symbolic function, pointing both to the external context of globalization and migration (which results in the characters’ disorientation and to an interior space which can be interpreted either as a source of unrepressed energies and creativity (in a Romantic vein or as the space of the abject (in the manner of Julia Kristeva. The article sets out to investigate the complex ways in which the Orphic myth and katabasis are employed to shed light on the psychology of the creative artist and on the reconfiguration of identity that becomes the task of the postcolonial migrant subject. The journey into the underworld functions simultaneously as an allegory of artistic creation and identity reconstruction.

    2011-03-01

    Inappropriate behavior during common handling procedures with horses is often subject to aversive treatment. The present study replicated and extended previous findings using differential reinforcement to shape appropriate equine handling behavior. In Study 1, a multiple baseline across subjects design was used with four horses to determine first the effects of shaping target-touch responses and then successive approximations of full truck loading under continuous and intermittent schedules of reinforcement. Full loading responses were shaped and maintained in all four horses and occurrences of inappropriate behaviors reduced to zero. Generalization of the loading response was also observed to both a novel trainer and trailer. In Study 2, a changing criterion design was used to increase the duration of feet handling with one horse. The horse's responding reached the terminal duration criterion of 1min and showed consistent generalization and one-week maintenance. Overall, the results of both studies support the use of applied equine training systems based on positive reinforcement for increasing appropriate behavior during common handling procedures. 2011 Elsevier B.V.

    Foot pathology is a common and important health concern in captive rhinoceroses worldwide, but osteopathologies are rarely diagnosed, partly because of a lack of radiographic protocols. Here, we aimed to develop the first radiographic protocol for rhinoceros feet and describe the radiographic anatomy of the white rhinoceros (Ceratotherium simum) hind foot (pes). Computed tomographic images were obtained of nine cadaver pedes from seven different white rhinoceroses and assessed for pathology. A single foot deemed free of pathology was radiographed using a range of different projections and exposures to determine the best protocol. 3D models were produced from the CT images and were displayed with the real radiographs to describe the normal radiographic anatomy of the white rhinoceros pes. An optimal radiographic projection was determined for each bone in the rhinoceros pes focusing on highlighting areas where pathology has been previously described. The projections deemed to be most useful were D60Pr-PlDiO (digit III), D45Pr45M-PlDiLO (digit II), and D40Pr35L-PlDiLO (digit IV). The primary beam was centered 5-7 cm proximal to the cuticle on the digit of interest. Articular surfaces, ridges, grooves, tubercles, processes and fossae were identified. The radiographic protocol we have developed along with the normal radiographic anatomy we have described will allow for more accessible and effective diagnosis of white rhinoceros foot osteopathologies.

  20. A prospective study of Japas′ osteotomy in paralytic pes cavus deformity in adolescent feet

    Full Text Available Background: Pes cavus is a progressive and ugly deformity of the foot. Although initially the deformity is painless, with time, painful callosities develop under metatarsal heads and arthritis supervenes later in feet. Mild deformities can be treated with corrective shoes, or foot exercises. However, in others, operative treatment is imperative. Soft tissue operations are largely unsatisfactory and temporary. Bony operations give permanent correction. We present our series of 18 patients of pes cavus in the adolescent age group, treated by Japas′ V-osteotomy of the tarsus. Materials and Methods: 18 patients of paralytic pes cavus deformity were treated by Japas osteotomy, between March 1995 and 2005, at our institute. The age of the patients ranged from 8.6 to 15 years (mean 11.3; 10 were boys and 8 girls. All cases had unilateral involvement, and all, but one, were post-polio cases. Result: The mean follow-up is 5.4 years. Of the 18 patients, 14 had excellent or good corrections; 4 had poor correction/complications. However, those patients could be salvaged by triple arthordesis or Dwyer′s calcaneal osteotomy. Conclusion: Japas′ osteotomy is a satisfactory option for correction of pes cavus deformity in adolescents. In patients who have rigid hind foot equinus or varus, however, the results are compromised.

  1. Effects of surface characteristics on the plantar shape of feet and subjects' perceived sensations.

    Orthotics and other types of shoe inserts are primarily designed to reduce injury and improve comfort. The interaction between the plantar surface of the foot and the load-bearing surface contributes to foot and surface deformations and hence to perceived comfort, discomfort or pain. The plantar shapes of 16 participants' feet were captured when standing on three support surfaces that had different cushioning properties in the mid-foot region. Foot shape deformations were quantified using 3D laser scans. A questionnaire was used to evaluate the participant's perceptions of perceived shape and perceived feeling. The results showed that the structure in the mid-foot could change shape, independent of the rear-foot and forefoot regions. Participants were capable of identifying the shape changes with distinct preferences towards certain shapes. The cushioning properties of the mid-foot materials also have a direct influence on perceived feelings. This research has strong implications for the design and material selection of orthotics, insoles and footwear.

  2. The underlying structure of skin wrinkles: a hyperspectral approach to crows feet

    Skin wrinkles are visually perceived by consumers but they are also known to possess an underlying structure not apparent at the surface of the skin. This underlying structure can be brought out by polarized hyperspectral imaging. Wrinkle patterns of eye crow's feet are used as example to show a deeper existing pattern and their characterization versus age on a group of volunteers. The skin inhomogeneity changes within each layer of the skin and can be observed in the shorter wavelength region of the spectrum, about 450nm to 500nm which are well suited to image skin surface inhomogeneities within the central and deep epidermis. Imaging in the 550nm range can serve as a larger scale topology reference because of its deeper penetration into the upper dermis. This serves to bring out the underlying wrinkle pattern as imprinted by collagen anisotropies around deep folds but unapparent to the eye yet. The approach has potential applications in evaluating the internal skin patterns non visible to the eye by mapping their spectral dispersion. This method has thus potentials to evaluate the extent of subsurface structures such as acne and other scars and thereby the efficacy of treatments.

  3. Design and Stability Analysis of a 3D Rimless Wheel with Flat Feet and Ankle Springs

    A two-dimensional rimless wheel provides a simple model of bipedal walking. The motion of the rimless wheel is stable, and this particular property has clarified the fundamental role of a swing leg in planar bipedal walking that addresses the problem of falling forward. In this paper, a three-dimensional rimless wheel is investigated as a simple model of three-dimensional bipedal walking. The 3D rimless wheel model is useful in understanding the essential dynamics of 3D bipedal locomotion. The model consists of two rimless wheels connected by a link at the center of the wheels, and flat feet connected to the spokes with springs. The first numerical stability studies indicated that the motion of the 3D rimless wheel could be unstable; however, numerical simulations and experimental results showed that for a given slope and physical parameters, including the spring constant at the ankles, a stable motion is obtained. This indicates the usefulness of ankle springs in providing stable bipedal locomotion in three-dimensions.

    ABSTRACT Aquatic and terrestrial animals have different swimming performances and mechanical efficiencies based on their different swimming methods. To explore propulsion in swimming frogs, this study calculated mechanical efficiencies based on data describing aquatic and terrestrial webbed-foot shapes and swimming patterns. First, a simplified frog model and dynamic equation were established, and hydrodynamic forces on the foot were computed according to computational fluid dynamic calculations. Then, a two-link mechanism was used to stand in for the diverse and complicated hind legs found in different frog species, in order to simplify the input work calculation. Joint torques were derived based on the virtual work principle to compute the efficiency of foot propulsion. Finally, two feet and swimming patterns were combined to compute propulsive efficiency. The aquatic frog demonstrated a propulsive efficiency (43.11%) between those of drag-based and lift-based propulsions, while the terrestrial frog efficiency (29.58%) fell within the range of drag-based propulsion. The results illustrate the main factor of swimming patterns for swimming performance and efficiency. PMID:28302669

  5. Treatment of sandal burns of the feet in children in a moist environment.

    Burns to children's feet are often due to scalds, from hot tap water, as an infant's skin is thinner and hence more susceptible to a full-thickness injury. In Central Asia, and particularly in Uzbekistan, many episodes of burns take place at homes because of using sandal heaters. In the case of sandal burns of the foot, it usually is not only skin that is injured but also underlying tissues: subcutaneous fat, fasciae, muscles and even bones. Many controlled studies have confirmed that wounds heal more readily in a moist, physiological environment. After performing the toilet of burn wounds of the foot, we applied Dermazin cream on the affected areas and then the foot was placed onto a polyethylene packet of large size and fixed by a bandage. Measurement of wound water evaporation was performed every day post-burn. Surgery was usually performed 15-17 days after burn by applying a perforated skin graft or a 0.2-0.3-mm-thick non-perforated skin graft. The procedures helped to improve the general condition of patients, shortened their stay in hospital and also reduced expenses and lessened joint deformities and contracture deformities.

    Conclusions: Diabetic foot has varied presentation. The prevalence of diabetes mellitus and its surgical complications can be attributed to poor patient knowledge, education and awareness of the disease. Patient education for care of feet such as pairing of nails, wearing proper footwear and prompt reporting to doctor in case of early lesions is essential.

The limitation of berberine seems to be its poor oral bioavailability, which is affected by the presence, in enterocytes, of P-glycoprotein – an active adenosine triphosphate (ATP-consuming efflux protein that extrudes berberine into the intestinal lumen, thus limiting its absorption. According to some authors, silymarin, derived from Silybum marianum, could be considered a P-glycoprotein antagonist. Aim: The study aimed to evaluate the role played by a possible P-glycoprotein antagonist (silymarin, when added to a product containing Berberis aristata extract, in terms of benefits to patients with type 2 diabetes. Methods: The study enrolled 69 patients with type 2 diabetes in suboptimal glycemic control who were treated with diet, hypoglycemic drugs, and in cases of concomitant alterations of the lipid profile, hypolipidemic agents. The patients received an add-on therapy consisting of either a standardized extract of Berberis aristata (titrated in 85% berberine corresponding to 1,000 mg/day of berberine, or Berberol®, a fixed combination containing the same standardized extract of Berberis aristata plus a standardized extract of Silybum marianum (titrated as .60% in silymarin, for a total intake of 1,000 mg/day of berberine and 210 mg/day of silymarin.

    Of all the detrimental effects of spinal cord injury (SCI), one of the most devastating is the disruption of the ability to perform functional movement. Very little is known on the recovery of hindlimb joint kinematics after clinically-relevant contusive thoracic lesion in experimental animal models. A new functional assessment instrument, the dynamic feet distance (DFD) was used to describe the distance between the two feet throughout the gait cycle in normal and affected rodents. The purpose of this investigation was the evaluation and characterization of the DFD during treadmill locomotion in normal and T9 contusion injured rats, using three-dimensional (3D) instrumented gait analysis. Despite that normal and injured rats showed a similar pattern in the fifth metatarsal head joints distance excursion, we found a significantly wider distance between the feet during the entire gait cycle following spinal injury. This is the first study to quantify the distance between the two feet, throughout the gait cycle, and the biomechanical adjustments made between limbs in laboratory rodents after nervous system injury.

The purpose of the present study was (i) to investigate the association between fluid intake and a potential development of peripheral oedemas leading to an increase of the feet volume in 100-km ultra-marathoners and (ii) to evaluate a possible association between the changes in plasma sodium concentration ([Na+]) and changes in feet volume. Methods In seventy-six 100-km ultra-marathoners, body mass, plasma [Na+], haematocrit and urine specific gravity were determined pre- and post-race. Fluid intake and the changes of volume of the feet were measured where the changes of volume of the feet were estimated using plethysmography. Results Body mass decreased by 1.8 kg (2.4%) (p 0.05). Plasma volume and urine specific gravity increased (p marathon was due to an increased fluid intake. PMID:22472466

  6. A High Percentage of Beef Bull Pictures in Semen Catalogues Have Feet and Lower Legs that Are Not Visible

    Full Text Available A total of 1379 beef bull pictures were surveyed to determine visibility of feet and legs from four American semen company websites. Five different breeds were represented: Angus, Red Angus, Hereford (polled and horned, Simmental, and Charolais. In addition to visibility, data on other variables were collected to establish frequencies and correlations. These included breed, color, material that obscured visibility, such as grass, picture taken at livestock show or outside, semen company, photographer, video, and age of bull. A foot and leg visibility score was given to each bull picture. Only 19.4% of the pictures had fully visible feet and legs. Both the hooves and dewclaws were hidden on 32.5% of the pictures. Correlation between bull’s birthdate and the first four visibility scores was statistically significant (P < 0.0001. As age increased the feet and legs were more likely to be visible in the bull’s picture. This may possibly be due to greater availability of both photo editing software and digital photography. One positive finding was that 6% of the bulls had a video of the bull walking which completely showed his feet and legs.

    1984-01-01

    The healing of digital and transmetatarsal forefoot amputations was compared with the systolic digital and ankle blood pressure, both measured with a strain-gauge, and with the skin perfusion pressure on the forefoot measured with the isotope washout technique. In 85 out of 134 legs (63 per cent)...... 20-29 mm Hg: 13 out of 22; SDBP greater than or equal to 30 mm Hg: 51 out of 65. Ankle pressures and skin perfusion pressures were less useful. Invasive infection was present in 40 out of 102 diabetic legs and, next to ischaemia, was the major determinant of the healing results....

  11. Lucy's flat feet: the relationship between the ankle and rearfoot arching in early hominins.

    Directory of Open Access Journals (Sweden)

    Jeremy M DeSilva

    Full Text Available BACKGROUND: In the Plio-Pleistocene, the hominin foot evolved from a grasping appendage to a stiff, propulsive lever. Central to this transition was the development of the longitudinal arch, a structure that helps store elastic energy and stiffen the foot during bipedal locomotion. Direct evidence for arch evolution, however, has been somewhat elusive given the failure of soft-tissue to fossilize. Paleoanthropologists have relied on footprints and bony correlates of arch development, though little consensus has emerged as to when the arch evolved. METHODOLOGY/PRINCIPAL FINDINGS: Here, we present evidence from radiographs of modern humans (n = 261 that the set of the distal tibia in the sagittal plane, henceforth referred to as the tibial arch angle, is related to rearfoot arching. Non-human primates have a posteriorly directed tibial arch angle, while most humans have an anteriorly directed tibial arch angle. Those humans with a posteriorly directed tibial arch angle (8% have significantly lower talocalcaneal and talar declination angles, both measures of an asymptomatic flatfoot. Application of these results to the hominin fossil record reveals that a well developed rearfoot arch had evolved in Australopithecus afarensis. However, as in humans today, Australopithecus populations exhibited individual variation in foot morphology and arch development, and "Lucy" (A.L. 288-1, a 3.18 Myr-old female Australopithecus, likely possessed asymptomatic flat feet. Additional distal tibiae from the Plio-Pleistocene show variation in tibial arch angles, including two early Homo tibiae that also have slightly posteriorly directed tibial arch angles. CONCLUSIONS/SIGNIFICANCE: This study finds that the rearfoot arch was present in the genus Australopithecus. However, the female Australopithecus afarensis "Lucy" has an ankle morphology consistent with non-pathological flat-footedness. This study suggests that, as in humans today, there was variation in arch

    Vigilance is affected by induced and spontaneous skin temperature fluctuations. Whereas sleep deprivation strongly affects vigilance, no previous study examined in detail its effect on human skin temperature fluctuations and their association with vigilance. In a repeated-measures constant routine design, skin temperatures were assessed continuously from 14 locations while performance was assessed using a reaction time task, including eyes-open video monitoring, performed five times a day for 2 days, after a normal sleep or sleep deprivation night. Participants were seated in a dimly lit, temperature-controlled laboratory. Eight healthy young adults (five males, age 22.0 ± 1.8 yr (mean ± standard deviation)). One night of sleep deprivation. Mixed-effect regression models were used to evaluate the effect of sleep deprivation on skin temperature gradients of the upper (ear-mastoid), middle (hand-arm), and lower (foot-leg) body, and on the association between fluctuations in performance and in temperature gradients. Sleep deprivation induced a marked dissociation of thermoregulatory skin temperature gradients, indicative of attenuated heat loss from the hands co-occurring with enhanced heat loss from the feet. Sleep deprivation moreover attenuated the association between fluctuations in performance and temperature gradients; the association was best preserved for the upper body gradient. Sleep deprivation disrupts coordination of fluctuations in thermoregulatory skin temperature gradients. The dissociation of middle and lower body temperature gradients may therefore be evaluated as a marker for sleep debt, and the upper body gradient as a possible aid in vigilance assessment when sleep debt is unknown. Importantly, our findings suggest that sleep deprivation affects the coordination between skin blood flow fluctuations and the baroreceptor-mediated cardiovascular regulation that prevents venous pooling of blood in the lower limbs when there is the orthostatic

    Providing appropriate prosthetic feet to those with limb loss is a complex and subjective process influenced by professional judgment and payer guidelines. This study used a small load cell (Europa™) at the base of the socket to measure the sagittal moments during walking with three objective categories of prosthetic feet in eleven individuals with transtibial limb loss with MFCL K2, K3 and K4 functional levels. Forefoot stiffness and hysteresis characteristics defined the three foot categories: Stiff, Intermediate, and Compliant. Prosthetic feet were randomly assigned and blinded from participants and investigators. After laboratory testing, participants completed one week community wear tests followed by a modified prosthetics evaluation questionnaire to determine if a specific category of prosthetic feet was preferred. The Compliant category of prosthetic feet was preferred by the participants (P=0.025) over the Stiff and Intermediate prosthetic feet, and the Compliant and Intermediate feet had 15% lower maximum sagittal moments during walking in the laboratory (P=0.0011) compared to the Stiff feet. The activity level of the participants did not change significantly with any of the wear tests in the community, suggesting that each foot was evaluated over a similar number of steps, but did not inherently increase activity. This is the first randomized double blind study in which prosthetic users have expressed a preference for a specific biomechanical characteristic of prosthetic feet: those with lower peak sagittal moments were preferred, and specifically preferred on slopes, stairs, uneven terrain, and during turns and maneuvering during real world use.

    We investigated whether self-reported racial discrimination was associated with continuous glucose levels and variability in individuals with diabetes, and whether diabetes distress mediated these associations. Seventy-four Black and White women with type 2 diabetes completed the Experience of Discrimination scale, a measure of lifetime racial discrimination, and the Problem Areas in Diabetes, a measure of diabetes distress. Participants wore a continuous glucose monitor for 24 h after 8 h of fasting, a standard meal, and a 4-h run in period. Higher discrimination predicted higher continuous mean glucose and higher standard deviation of glucose. For both mean and standard deviation of glucose, a race × discrimination interaction indicated a stronger relationship between discrimination and glucose for Whites than for Blacks. Diabetes distress mediated the discrimination-mean glucose relationship. Whites who report discrimination may be uniquely sensitive to distress. These preliminary findings suggest that racial discrimination adversely affects glucose control in women with diabetes, and does so indirectly through diabetes distress. Diabetes distress may be an important therapeutic target to reduce the ill effects of racial discrimination in persons with diabetes.

    2007-01-01

    Diabetic foot problems are common throughout the world, and result in major medical, social and economic consequences for the patients, their families, and society. Foot ulcers are likely to be of neuropathic origin and, therefore, are eminently preventable. Individuals with the greatest risk of ulceration can easily be identified by careful clinical examination of their feet: education and frequent follow-up is indicated for these patients. When infection complicates a foot ulcer, the combination can be limb-threatening, or life-threatening. Infection is defined clinically, but wound cultures assist in identification of causative pathogens. Tissue specimens are strongly preferred to wound swabs for wound cultures. Antimicrobial therapy should be guided by culture results, and although such therapy may cure the infection, it does not heal the wound. Alleviation of the mechanical load on ulcers (offloading) should always be a part of treatment. Plantar neuropathic ulcers typically heal in 6 weeks with nonremovable casts, because pressure at the ulcer site is mitigated and compliance is enforced. The success of other approaches to offloading similarly depends on the patient's adherence to the strategy used for pressure relief.

  20. Potential mechanisms of neuropathic pain in diabetes.

    Science.gov (United States)

    Calcutt, Nigel A

    2002-01-01

    Abnormal sensations and pain are features of approximately 10% of all cases of diabvetic neuropathy and can cause marked diminution in the quality of life for these patients. The quality and distribution of pain are variable, although descriptions of burning pain in the hands and feet are commonly reported. Like other neuropathic pain states, painful diabetic neuropathy has an unknown pathogenesis and, in many cases, is not alleviated by nonsteriodal anti-inflammatory drugs or opiates. In the last decase, a number of behavioral and physiologic studies have revealed indices of sensory dysfunction in animal models of diabetes. These include hyperalgesia to mechanical and noxious chemical stimuli and allodynia to light touch. Animal models of painful diabetic neuropathy have been used to investigate the therapeutic potential of a range of experimental agents and also to explore potential etiologic mechanisms. There is relatively little evidence to suggest that the peripheral sensory nerves of diabetic rodents exhibit spontaneous activity or increased responsiveness to peripheral stimuli. Indeed, the weight of eveidence suggests that sensory input to the spinal cord is decreased rather than increased in diabetic rodents. Aberrant spinal or supraspinal modulation of sensory processing may therefore be involved in generating allodynia and hyperalgesia in these models. Studies have supported a role for spinally mediated hyeralgesia in diabetic rats that may reflect either a response to diminished peripheral input or a consequence of hyperglycemia on local or descending modulatory systems. Elucidating the affects of diabetes on spinal sensory processing may assist development of novel therapeutic strategies for preventing and alleviating painful diabetic neuropathy.

  1. Diabetic nephropathy

    2009-09-01

    Full Text Available Abstract Diabetic nephropathy is the leading cause of chronic renal disease and a major cause of cardiovascular mortality. Diabetic nephropathy has been categorized into stages: microalbuminuria and macroalbuminuria. The cut-off values of micro- and macroalbuminuria are arbitrary and their values have been questioned. Subjects in the upper-normal range of albuminuria seem to be at high risk of progression to micro- or macroalbuminuria and they also had a higher blood pressure than normoalbuminuric subjects in the lower normoalbuminuria range. Diabetic nephropathy screening is made by measuring albumin in spot urine. If abnormal, it should be confirmed in two out three samples collected in a three to six-months interval. Additionally, it is recommended that glomerular filtration rate be routinely estimated for appropriate screening of nephropathy, because some patients present a decreased glomerular filtration rate when urine albumin values are in the normal range. The two main risk factors for diabetic nephropathy are hyperglycemia and arterial hypertension, but the genetic susceptibility in both type 1 and type 2 diabetes is of great importance. Other risk factors are smoking, dyslipidemia, proteinuria, glomerular hyperfiltration and dietary factors. Nephropathy is pathologically characterized in individuals with type 1 diabetes by thickening of glomerular and tubular basal membranes, with progressive mesangial expansion (diffuse or nodular leading to progressive reduction of glomerular filtration surface. Concurrent interstitial morphological alterations and hyalinization of afferent and efferent glomerular arterioles also occur. Podocytes abnormalities also appear to be involved in the glomerulosclerosis process. In patients with type 2 diabetes, renal lesions are heterogeneous and more complex than in individuals with type 1 diabetes. Treatment of diabetic nephropathy is based on a multiple risk factor approach, and the goal is retarding the

    Podoconiosis (mossy foot) is a neglected non-filarial elephantiasis considered to be caused by predisposition to cumulative contact of uncovered feet to irritative red clay soil of volcanic origins in the tropical regions. Data from structured observational studies on occurrence of Podoconiosis and related factors are not available in Kenya. To establish the occurrence and aspects associated with Podoconiosis, a cross-sectional survey was implemented in an area located within 30 km from the foot of volcanic Mount Longonot in the Great Rift Valley in Kenya. Five villages and 385 households were selected using multistage and systematic random sampling procedures respectively during the survey. Podoconiosis was determined by triangulating (1) the clinical diagnosis, (2) molecular assaying of sputum samples to rule out Wuchereria bancrofti microfilaria and (3) determining the concentration of six elements and properties in the soil known to be associated with Podoconiosis. A structured questionnaire was used to identify possible risk factors. Univariable and multivariable Poisson regression analyses were carried out to determine factors associated with Podoconiosis. Thirteen participants were clinically positive for Podoconiosis giving an overall prevalence of 3.4%. The prevalence ranged between 0% and 18.8% across the five villages. Molecular assay for W. bancrofti test turned negative in the 13 samples. The following factors were positively associated with the Podoconiosis prevalence (Pwearing shoes, (vi) soil pH, and (vii) village. Unexpectedly, the concentration of soil minerals previously thought to be associated with Podoconiosis was found to be negatively associated with the Podoconiosis prevalence (Pwearing shoes and village turned out significant (P≤0.05). By modeling the different soil mineral concentrations and pH while adjusting for the variable frequency of wearing shoes, only iron concentration was significant and in the negative dimension (P≤0

    Early identification of diabetic foot complications and their precursors is essential in preventing their devastating consequences, such as foot infection and amputation. Frequent, automatic risk assessment by an intelligent telemedicine system might be feasible and cost effective. Infrared thermography is a promising modality for such a system. The temperature differences between corresponding areas on contralateral feet are the clinically significant parameters. This asymmetric analysis is hindered by (1) foot segmentation errors, especially when the foot temperature and the ambient temperature are comparable, and by (2) different shapes and sizes between contralateral feet due to deformities or minor amputations. To circumvent the first problem, we used a color image and a thermal image acquired synchronously. Foot regions, detected in the color image, were rigidly registered to the thermal image. This resulted in 97.8%±1.1% sensitivity and 98.4%±0.5% specificity over 76 high-risk diabetic patients with manual annotation as a reference. Nonrigid landmark-based registration with B-splines solved the second problem. Corresponding points in the two feet could be found regardless of the shapes and sizes of the feet. With that, the temperature difference of the left and right feet could be obtained.

    Pancreatitis, panniculitis, and polyarthritis (PPP) syndrome is extremely rare and presents as a triad of the three diseases. The patient usually presents with mild or absent abdominal symptoms. Here, we report on a case of a 66-year-old male who presented with pain and swelling in both legs and mild abdominal pain. He was diagnosed with acute pancreatitis by pancreatic enzyme analysis and abdominal computed tomography (CT) and with skin lesions of panniculitis through a biopsy. Magnetic resonance imaging (MRI) revealed multifocal intraosseous fat necrosis and arthritis involving both the feet and the knees. Therefore, we report a case of PPP syndrome with intraosseous fat necrosis involving both the feet and the knees. (orig.)

    Methods are described for generating 3D time-resolved contrast-enhanced MR angiograms of the hands and feet. Given targeted spatial resolution and frame times, it is shown that acceleration of about one order of magnitude or more is necessary. This is obtained by a combination of 2D Sensitivity Encoding (SENSE) and homodyne (HD) acceleration methods. Image update times from 3.4 to 6.8 sec are provided in conjunction with view sharing. Modular receiver coil arrays are described which can be designed to the targeted vascular region. Images representative of the technique are generated in the vasculature of the hands and feet in volunteers and in patient studies. PMID:21698702

  7. Diabetic foot ulcers: practical treatment recommendations.

    Edmonds, Michael

    2006-01-01

    neuroischaemic foot ulcers may need vascular intervention (vascular control). In stage 4, microbiological control is crucial and severe infections need intravenous antibacterial therapy, and urgent assessment of the need for surgical drainage and debridement. Without urgent treatment, severe infections will progress to necrosis. In stage 5, necrosis can be divided into wet and dry necrosis. Wet necrosis in neuropathic feet requires intravenous antibacterials and surgical debridement, and wet necrosis in neuroischaemic feet also needs vascular reconstruction. Aggressive management of diabetic foot ulceration will reduce the number of feet proceeding to infection and necrosis, and thus reduce the number of major amputations in diabetic patients.

    Contrary to stance-phase dorsiflexion of conventional prosthetic feet, the microprocessor-controlled Proprio foot permits swing-phase dorsiflexion on stairs. The purpose of this study was to compare Symmetry in External Work (SEW) between a microprocessor-controlled foot and conventional prosthetic feet in two groups with unilateral transtibial amputation (Medicare Functional Classification Levels K-Level-2 and K-Level-3) during stair ascent and descent. Ten subjects were evaluated while wearing three conventional prosthetic feet- solid ankle cushion heel (SACH), stationary attachment flexible endoskeleton (SAFE), and Talux-and the Proprio foot using a study socket and were given a 10- to 14-day accommodation period with each foot. Ground reaction forces were collected using F-scan sensors during stair ascent and descent. The SEW between the intact and amputated limbs was calculated for each foot. During stair ascent, the Proprio foot resulted in a higher interlimb symmetry than conventional prosthetic feet, with significant differences between the Pro prio and SACH/SAFE feet. The swing-phase dorsiflexion appeared to promote greater interlimb symmetry because it facilitated forward motion of the body, resulting in a heel-to-toe center of pressure trajectory. During stair descent, all feet had low symmetry without significant differences between feet. The movement strategy used when descending stairs, which is to roll over the edge of a step, had a greater influence on symmetry than the dorsiflexion features of prosthetic feet.

    During the past several decades, the number of both business and tourist travels has greatly increased. Among them are persons suffering from chronic diseases, including diabetics for whom travels pose the additional health-hazard. Irrespective of better education, self-control and constantly improving quality of specialistic equipment available, diabetics still are the group of patients requiring particular attention. In the case of travelling diabetics, problems may occur concerning the transport and storage of insulin, as well as control of glycaemia, all caused by irregularity of meals, variable diet, physical activity, stress, kinetosis (sea voyages), and the change of time zones. The travel may as well evoke ailments caused by the change of climate and concomitant diseases such as traveller's diarrhoea, malaria, etc. Apart from avoiding glycaemia fluctuations, important for retaining health of diabetics is the prevention of other diseases and carrying the necessary drugs.

    2014-01-01

    Diabetes insipidus is an uncommon disorder of water-electrolyte balance characterized by the excretion of abnormally large volumes of diluted urine (polyuria) and increased fluid intake (polydipsia). The disease may result from the insufficient production of vasopressin, its increased degradation, an impaired response of kidneys to vasopressin, or may be secondary to excessive water intake. Patients with severe and uncompensated symptoms may develop marked dehydration, neurologic symptoms and encephalopathy, and therefore diabetes insipidus can be a life-threatening condition if not properly diagnosed and managed. Patients with diabetes insipidus require treatment with desmopressin or drugs increasing sensitivity of the distal nephron to vasopressin, but this treatment may be confusing because of the disorder's variable pathophysiology and side-effects of pharmacotherapy. This review summarizes the current knowledge on different aspects of the pathophysiology, classification, clinical presentation, diagnosis, and management of diabetes insipidus. The reader is also provided with some practical recommendations on dealing with patients suffering from this disease.

    According to the verdict of the Supreme Court in 2005, an employer may dismiss an employee if their conduct (including dress) exposes the employer to losses or threatens his interests. The aim of the study was a holistic assessment of the pleiotropic effects of high-heeled pointed shoes on the health condition of women's feet, wearing them at work, in accordance with the existing rules of the "business dress code". A holistic multidisciplinary analysis was performed. It takes into account: 1) women employees of banks and other large corporations (82 persons); 2) 2D FEM computer model developed by the authors of foot deformed by pointed high-heeled shoes; 3) web site found after entering the code "business dress code". Over 60% of women in the office wore high-heeled shoes. The following has been found among people walking to work in high heels: 1) reduction in the quality of life in about 70% of cases, through periodic occurrence of pain and reduction of functional capacity of the feet; 2) increase in the pressure on the plantar side of the forefoot at least twice; 3) the continued effects the forces deforming the forefoot. 1. An evolutionary change of "dress code" shoes is necessary in order to lead to a reduction in non-physiological overload of feet and the consequence of their disability. 2. These changes are particularly urgent in patients with so-called "sensitive foot".

    Excessive weight and obesity are ranked among lifestyle diseases. In the case of weight gain, the effectiveness of therapy based on diet and physical activity depends considerably on patients themselves, but despite this the number of those who successfully manage to lose weight is still not satisfactory. Preventing or treating excessive weight gain in the intellectually disabled is extremely difficult since they have a higher risk for developing obesity. The below presented study assessed the effect of the degree of intellectual disability on nutritional status in adolescents with Down syndrome. It also focused on some correlations between the degree of disability and a selected constituent of the body posture, i.e. flat feet. A total of 54 males and 26 females with mild and moderate Down syndrome, aged 18.68 ± 1.73, residents of Special Needs Education Centre in Tarnów, Poland, participated in the study, in which body weight and height, BMI, fat tissue percentage and the longitudinal arch of the foot were measured. A total of 17.5% of individuals with mild and 50% of individuals with moderate ID were found overweight or obese. Weight gain more often occurred in females. It seemed that flat feet were affected to a greater extent by the participants' nutritional status than their degree of disability. The study found no unambiguous effect of the degree of disability on the nutritional status and flat feet in individuals with Down syndrome.

    Introduction: The purpose of this study was to assess the flap reconstructed hind feet of patients with MRI who were traumatized by land-mine. Materials and methods: T1 and T2 weighted images were obtained in 7 patients, 12 months later the reconstruction of their hind feet by myocutaneous flaps after land-mine trauma. Results: In all patients T2 signal intensities of the myocutaneous flaps were slightly high compared to normal undisturbed muscle. Slight vascular engorgement was noted in the vicinity of the flaps in all cases. There were ankle joint ankylose (n = 1), tarsal coalition (n = 3), sklerosis within the calcaneus (n = 1), bone cortex irregularities (n = 3), absence of calcaneus (n = 4), deformity in talus and bone marrow edema (n = 1), navicular edema (n = 2), remodeling in the superior aspect of talus neck (n = 2), absence of talus (n = 2), talocalcaneal ankylose (n = 1), small collection in the superior aspect of flap (n = 1), drenage canules (n = 1). Conclusion: In reconstructed hind feet by myocutaneus flaps done for land-mine traumas, MRI presents useful information by displaying detailed anatomy of the flaps, bones, joints, soft tissues and associated complications.

    Patients with cerebral palsy, syndromes, myopathies, and other forms of neurological impairment can develop planovalgus foot deformity of variable degrees of severity. Several techniques have already been described to resolve the deformity with variable results. Talonavicular arthrodesis is a well-known technique in adult patients, but to our knowledge, it has not been described in children with neurological impairment. We performed a retrospective chart and radiographic review of 18 neurological patients (10 boys, 8 girls) with a mean age of 11.3 ± 2.6 years (range, 7 to 19 y) who underwent talonavicular arthrodesis for flat foot deformity between 1998 and 2009, at our center. Of a total of 29 feet, talonavicular arthrodesis was judged satisfactory in 28 feet, whereas 1 had unsatisfactory results according to the Yoo clinical outcome scoring scale. Subjective observations reported that 3 feet from 2 patients were painful preoperatively and none after last follow-up. Functionally, 2 of 13 patients were able to stop using braces after surgery. The significant improvement achieved postoperatively in radiographic measurement angles was maintained at last follow-up without any loss of angle correction. Talonavicular arthrodesis seems to achieve a reliable hind foot fixation in flat foot in patients with neurological impairment. Case series.

    Full Text Available The use of the computers and other technical devices has increased. The aim of our work was to study the possible relation between self-reported foot symptoms and use of computers and cell phones using a questionnaire. The study was carried out as a cross-sectional study by posting a questionnaire to 15,000 working-age Finns. A total of 6121 responded, and 7.1% of respondents reported that they very often experienced pain, numbness, and aches in the feet. They also often experienced other symptoms: 52.3% had symptoms in the neck, 53.5% in had problems in the hip and lower back, and 14.6% often had sleeping disorders/disturbances. Only 11.2% of the respondents thought that their symptoms were connected to the use of desktop computers. We found that persons with symptoms in the feet quite often, or more often, had additional physical and mental symptoms. In future studies, it is important to take into account that the persons with symptoms in the feet may very often have other symptoms, and the use of computers can influence these symptoms.

    Painful diabetic neuropathy is a common complication of diabetes and can severely limit patients' daily functions. The aim of this pilot study was to evaluate the safety and effect of using a polyherbal formulation in reducing the symptoms of diabetic neuropathic pain in comparison with placebo among patients with type 2 diabetes. A total of 50 (M:F = 33:17) consecutive type 2 diabetes patients with painful diabetic neuropathy were enrolled in this study. All these patients had either two or more symptoms of diabetic neuropathy such as pain, burning and pricking sensations and numbness in their feet. They were randomly assigned to two groups: group 1 (n = 26) patients were treated with polyherbal formulation cream and group 2 (n = 24) patients were administered placebo. The patients were followed up for six months. Changes in the symptoms of painful diabetic neuropathy of each patient were recorded at baseline, third and sixth month using the Diabetic Neuropathic Score. The mean age of the patients, duration of diabetes and glycated haemoglobin (HbA 1c ) were similar in both groups at baseline. During follow up visits, there was a decrease in the HbA 1c levels in the study and control groups. The symptoms of painful diabetic neuropathy were also similar in both groups at baseline. A significant decrease in symptoms of neuropathic pain was observed among the group of patients treated with polyherbal formulation cream (76.9 per cent) compared to the placebo-treated group (12.5 per cent) (Pcream was found to be effective as well as safe to treat painful diabetic neuropathy. However, its long term use needs to be evaluated for any further effectiveness and side effects.

  4. Foot dimensions of elderly people with and without diabetes mellitus - a data basis for shoe design.

    Science.gov (United States)

    Chantelau, E; Gede, A

    2002-01-01

    Injuries from footwear are common in elderly people, particularly in those with diabetes mellitus and polyneuropathy. A common cause is a mismatch between foot and shoe. To assess the length and the breadth of the feet by an automatic measuring device in 568 patients with diabetic polyneuropathy and in 100 nondiabetic control subjects of the same mean age of 64 years. While the foot length in all cases matched well with the size of the normal footwear available on the market, more than two thirds of the feet were considerably broader than the normal footwear available. The foot breadth correlated variably with the foot length. Tables of foot dimensions for men and women are provided over the complete range of shoe sizes. This anthropometric data set on feet, which is the first conducted in elderly people, proves that most feet of elderly people with or without diabetic neuropathy do not fit ordinary casual footwear. Therefore, the construction of shoes according to the anthropometric data of elderly people is required in order to prevent foot injuries in this particular population. Copyright 2002 S.

    Full Text Available Background: This preliminary publication describes acute temperature effects after manual Khalifa therapy. Aims : The goal of this study was to describe temperature distribution and the effects on surface temperature of the knees and feet in patients with completely ruptured anterior cruciate ligament before and immediately after the manual therapy. Materials and Methods: Ten male patients were investigated with thermal imaging. An infrared camera operating at a wavelength range of 7.5-13 μm was used. Temperature was analyzed at three locations on both knees and in addition on both feet. Results: The study revealed that baseline temperature of the injured knee differed from that of the untreated control knee. After the therapy on the injured knee, the surface temperature was significantly increased on both knees (injured and control. There were no significant changes in the temperature of the feet. Conclusions: Further studies using continuous thermal image recording may help to explain the details concerning the temperature distribution.

    Full Text Available Our aim of this study was to compare the accuracy of three different modalities for testing sensory neuropathy in diabetic patients with and without diabetic foot problems. The three devices used included the pin-prick testing using the Neurotip® (PPT, the Semmes–Weinstein 5.07/10 g monofilament testing (SWMT, and the rapid-current perception threshold (R-CPT measurements using the Neurometer® testing. Our study population consisted of 54 patients (108 feet with diabetic foot problems treated at the National University Hospital in Singapore by our multi-disciplinary diabetic foot care team. Our results showed no difference in sensory neuropathy detected by PPT and 5.07/10 g SWMT in both the pathological and normal foot. In the pathological foot, there was significant increase in sensory neuropathy detected by the Neurometer® device at both the big toe and ankle sites as compared to PPT and 5.07/10 g SWMT. In the normal foot, there was a significant increase in sensory neuropathy detected by the Neurometer® device at the big toe site only as compared to PPT and 5.07/10 g SWMT. Finally, the Neurometer® measurements detected a statistically higher proportion of feet with sensory neuropathy as compared to detection by the PPT or 5.07/10 g SWMT.

  10. Diabetic dyslipidemia.

    Science.gov (United States)

    Wu, Liya; Parhofer, Klaus G

    2014-12-01

    Diabetic dyslipidemia is characterized by elevated fasting and postprandial triglycerides, low HDL-cholesterol, elevated LDL-cholesterol and the predominance of small dense LDL particles. These lipid changes represent the major link between diabetes and the increased cardiovascular risk of diabetic patients. The underlying pathophysiology is only partially understood. Alterations of insulin sensitive pathways, increased concentrations of free fatty acids and low grade inflammation all play a role and result in an overproduction and decreased catabolism of triglyceride rich lipoproteins of intestinal and hepatic origin. The observed changes in HDL and LDL are mostly sequence to this. Lifestyle modification and glucose control may improve the lipid profile but statin therapy mediates the biggest benefit with respect to cardiovascular risk reduction. Therefore most diabetic patients should receive statin therapy. The role of other lipid lowering drugs, such as ezetimibe, fibrates, omega-3 fatty acids, niacin and bile acid sequestrants is less well defined as they are characterized by largely negative outcome trials. This review examines the pathophysiology of diabetic dyslipidemia and its relationship to cardiovascular diseases. Management approaches will also be discussed.

  11. Subclinical Diabetes

    Directory of Open Access Journals (Sweden)

    LUÍS M.T.R. LIMA

    Full Text Available ABSTRACT Type 2 diabetes mellitus (T2DM is increasing in prevalence worldwide, and those non-diagnosed or misdiagnosed comprise a significant group compared to those diagnosed. Accumulated scientific evidence indicate that the current diagnostic markers (fasting glycemia, 2h glycemia after an oral glucose load and HbA1c are indeed late diagnostic criteria when considering the incidence of diabetes-related complications and comorbidities, which are also at high risk in some groups among normoglycemic individuals. Additionally, the earlier identification of future risk of diabetes is desirable since it would allow better adherence to preventive actions such as lifestyle intervention, ultimately avoiding complications and minimizing the economic impact/burden on health care expenses. Insulin resistance and hyperhormonemia (insulin, amylin, glucagon are non-disputable hallmarks of T2DM, which already takes place among these normoglycemic, otherwise health subjects, characterizing a state of subclinical diabetes. Insulin resistance and hyperinsulinemia can be computed from fasting plasma insulin as an independent variable in normoglycemia. An overview of the current diagnostic criteria, disease onset, complications, comorbidities and perspectives on lifestyle interventions are presented. A proposal for early detection of subclinical diabetes from routine evaluation of fasting plasma insulin, which is affordable and robust and thus applicable for the general population, is further suggested.

  12. Comparison between microprocessor-controlled ankle/foot and conventional prosthetic feet during stair negotiation in people with unilateral transtibial amputation

    2013-10-01

    Full Text Available Contrary to stance-phase dorsiflexion of conventional prosthetic feet, the microprocessor-controlled Proprio foot permits swing-phase dorsiflexion on stairs. The purpose of this study was to compare Symmetry in External Work (SEW between a microprocessor-controlled foot and conventional prosthetic feet in two groups with unilateral transtibial amputation (Medicare Functional Classification Levels K-Level-2 and K-Level-3 during stair ascent and descent. Ten subjects were evaluated while wearing three conventional prosthetic feet—solid ankle cushion heel (SACH, stationary attachment flexible endoskeleton (SAFE, and Talux-and the Proprio foot using a study socket and were given a 10- to 14-day accommodation period with each foot. Ground reaction forces were collected using F-scan sensors during stair ascent and descent. The SEW between the intact and amputated limbs was calculated for each foot. During stair ascent, the Proprio foot resulted in a higher interlimb symmetry than conventional prosthetic feet, with significant differences between the Proprio and SACH/SAFE feet. The swing-phase dorsiflexion appeared to promote greater interlimb symmetry because it facilitated forward motion of the body, resulting in a heel-to-toe center of pressure trajectory. During stair descent, all feet had low symmetry without significant differences between feet. The movement strategy used when descending stairs, which is to roll over the edge of a step, had a greater influence on symmetry than the dorsiflexion features of prosthetic fee

    Objectives: (1) To investigate the association between diabetes and marrow changes in the cuboid; and (2) to evaluate the influence of age, gender, body mass index (BMI) and use of insulin in the occurrence of marrow changes in the cuboid. Research design and methods: MR and X-ray foot examinations of 237 patients [94 males, 143 females; mean age, 47.1 years (range 16–93 years)], five of whom underwent bilateral examinations, were reviewed. MR and radiographic studies were analyzed for the presence of marrow edema and fractures in the cuboid. Findings were correlated with demographic data (age, gender) and clinical information (BMI and use of insulin). Results: Two hundred and forty two feet – 69 diabetic and 173 non-diabetic – were retrospectively evaluated. There was a higher prevalence of marrow edema and fractures in the diabetic cuboid (n = 31, 45%) compared to non-diabetic cuboid (n = 25, 14%, p = 0.02). A fracture line was seen in fourteen (20%) diabetic cuboid bones compared to 4 (2%) in non-diabetic cuboid bones (p < 0.0001). Eleven (79%) cases of cuboid fractures in the diabetic population were radiographically occult. Multivariate data analysis revealed an adjusted odds ratio of 4.416 (95% CI; 2.307, 8.454) for the relationship between marrow changes (edema and fractures) in the cuboid and diabetes. For each year of age, the odds of changes in the cuboid increased by 2.2% (95% CI; 1.001, 1.044). Conclusion: Despite not bearing weight, the cuboid bone is more vulnerable to marrow edema and fractures in diabetic patients compared to non-diabetic patients. Age seems to be an influential factor.

    The intravenous glucose tolerance test, IVGTT, has been used to evaluate patients in whom abnormalities in carbohydrate metabolism and diabetes mellitus are suspected. IVGTT, if analyzed using 'minimal models', or discrete-time methods, provides information on the sensitivity of glucose disappearance to insulin and on pancreatic sensitivity to glucose, information that cannot be obtained from direct analysis of the dynamic response alone. In a preliminary study, data obtained by intravenously injecting 18-FDG in four subjects was analyzed using a discrete-time model. The experimental details, the results and their implications will be discussed. (orig.)

    Full Text Available This paper describes the importance of diabetic retinopathy in the loss of visual function. We exposed the most important risk factors, such as diabetes duration, poor metabolic control, pregnancy, puberty, hypertension, poor control of blood lipids, renal disease, and sleep apnea syndrome. We describe the pathogenesis of the disease, small retinal vessel microangiopathies which produce extravasation, edema and ischemia phenomena. We put special emphasis on the vascular endothelial growth factor (VEGF and its pathogenic importance. They are also described the main clinical symptoms as microaneurysms, intraretinal hemorrhages, hard and soft exudates, intraretinal microvascular abnormalities (IRMA, venous disorders, formation of new vessels and diabetic macular edema (the latter being the most common cause of vision loss. Finally we describe the latest diagnostic techniques and eye treatment, with special emphasis on obesity surgery importance as more important preventive factor to eliminate the predisposing and precipitating disease symptoms.

    Full Text Available Introduction: Body posture is an individual motion habit. It is variable and depends on the gender, age, structure of the body but also on mental and physical state. Although it is difficult to formulate a universal definition of correct body posture, the opinion that its elementary feature is symmetry is beyond any doubt. Such symmetry is related to the position of particular anatomical points and effects of static and dynamic forces. Aim of the research: To assess the relations between the pelvis position in the frontal plane, the static load on the lower limbs and architecture of the feet. The following features were analysed in a group of young, healthy and particularly physically active women and men: the frequency of asymmetry related to pelvis position, the load on the lower limbs related to body weight and foot architecture. Material and methods: The study group consisted of 100 students of physical education. To assess the position of the pelvis a palpable-visual method was used. Clarke’s method was applied to characterize the foot architecture determined by the position of standing with one leg on the CQ Elektronik podoscope. The static load on the lower limbs was assessed using the stabilographic platform EMILDUE from Technomex. Results : Collected data and observations show frequent asymmetric changes of pelvis position in the frontal plane and incorrect balance of the body in the standing position. The change of static load on the lower limbs influences the longitudinal architecture of the feet and this influence is statistically significant. Increased asymmetry of the pelvis in the frontal plane is related to profound disorder of body balance. Conclusions : Asymmetric position of the pelvis is associated with asymmetric arching of the feet and asymmetric body weight distribution. Full symmetric position of the pelvis is rare even among young people who are physically active.

    Increasing atmospheric carbon dioxide (CO2) has resulted in a change in seawater chemistry and lowering of pH, referred to as ocean acidification. Understanding how different organisms and processes respond to ocean acidification is vital to predict how marine ecosystems will be altered under future scenarios of continued environmental change. Regenerative processes involving biomineralization in marine calcifiers such as sea urchins are predicted to be especially vulnerable. In this study, the effect of ocean acidification on regeneration of external appendages (spines and tube feet) was investigated in the sea urchin Lytechinus variegatus exposed to ambient (546 µatm), intermediate (1027 µatm) and high (1841 µatm) partial pressure of CO2 (pCO2) for eight weeks. The rate of regeneration was maintained in spines and tube feet throughout two periods of amputation and regrowth under conditions of elevated pCO2. Increased expression of several biomineralization-related genes indicated molecular compensatory mechanisms; however, the structural integrity of both regenerating and homeostatic spines was compromised in high pCO2 conditions. Indicators of physiological fitness (righting response, growth rate, coelomocyte concentration and composition) were not affected by increasing pCO2, but compromised spine integrity is likely to have negative consequences for defence capabilities and therefore survival of these ecologically and economically important organisms.

    [Purpose] This study was conducted to determine the difference in foot pressures between flat and normal feet at different gait speeds on an ascending slope. [Subjects] This study enrolled 30 adults with normal (n=15) and flat feet (n=15), with ages from 21 to 30 years old, who had no history of neurological disorders or gait problems. A treadmill was used for the analysis of kinematic features during gait, using a slope of 10%, and gait velocities of slow, normal, and fast. [Methods] A foot pressure analyzer was used to measure changes in foot pressure. [Results] Compared to the normal subjects, the foot pressure of the flatfoot subjects showed a significant increase in the 2–3rd metatarsal region with increasing gait speed, whereas there were significant decreases in the 1st toe and 1st metatarsal regions with increasing gait speed. [Conclusion] The body weight of adults with flatfoot was concentrated on the 2–3rd metatarsal region during the stance phase and increased with walking speed on the ascending slope due to weakening of function of the medial longitudinal arch.

    Full Text Available Introduction  Diabetes is a globally major public health problem. Its evolution is insidious and silent before the appearance of serious complications as a consequence in terms of morbidity than of mortality.  Complications in the feet are among the most frequent and feared. This study helps identify factors associated with diabetic foot in diabetic patients in the province of Tetouan in public and private sector.Methods This is a case-control study in which 136 diabetic patients monitored in the public and private sector in the province of Tetouan were chosen. 68 patients had diabetic foot and 68 were diabetic patients without this complication. Data were collected from patients’ records and supplemented by interviews. The factors compared between the two groups were socio-demographic, biological and related to diabetes and lifestyle. These risk factors were determined by bivariate and multivariate analyses.Results Statistically significant associations were found between diabetic foot and several factors including: the irregular monitoring of patients: ORadjusted = 7.7 [1.9-23], the rate of glycated hemoglobin: ORadjusted = 1.7 [1.2-2.3], diabetes duration: ORadjusted = 1.2 [1.03-1.26], and physical activity ORadjusted = 1.1 [0.02-0.9]. However, no association was found between diabetic foot and the level of education or occupation.Conclusion To prevent the development of diabetic foot, more attention should be given to diabetic patients whose diabetes duration is long, patient monitoring should be regular and diabetes control should be optimal. In addition, physical activity is recommended for diabetic patients as part of promoting healthy lifestyles

    While lifestyle interventions involving exercise and a healthy diet in high-risk adults have been found to reduce progression to type 2 diabetes by >50%, little attention has been given to the potential benefits of such strategies in women with a history of gestational diabetes mellitus (GDM). We conducted a literature search of PubMed for English language studies of randomized controlled trials of lifestyle interventions among women with a history of GDM. In total, nine studies were identified which fulfilled the eligibility criteria. The majority of randomized trials of lifestyle interventions in women with GDM have been limited to pilot or feasibility studies. However, preliminary findings suggest that such interventions can improve diabetes risk factors in women with a history of GDM. Larger, well-designed controlled randomized trials are needed to assess the effects of lifestyle interventions on preventing subsequent progression to type 2 diabetes among women with GDM.

    Full Text Available We examined the application of outcome measures to determine changes in function caused by standardized functional prosthetic gait training and the use of four different prosthetic feet in people with unilateral transtibial limb loss. Two self-report measures (Prosthetic Evaluation Questionnaire-Mobility Scale [PEQ-13] and Locomotor Capabilities Index [LCI], and three performance-based measures (Amputee Mobility Predictor with a prosthesis [AMPPRO], 6-minute walk test [6MWT] and step activity monitor [SAM] were used. Ten people with unilateral transtibial limb loss, five with peripheral vascular disease (PVD and five without PVD, completed testing. Subjects were tested at baseline and after receiving training with their existing prosthesis and with the study socket and four prosthetic feet, i.e., SACH (solid ankle cushion heel, SAFE (stationary attachment flexible endoskeletal, Talux, and Proprio feet, over 8 to 10 weeks. Training was administered between testing sessions. No differences were detected by the PEQ-13, LCI, 6MWT, or SAM following training and after fitting with test feet. The AMPPRO demonstrated differences following training with the existing prosthesis in the PVD group and between selected feet from baseline testing (p feet.

    The aim of this study is to estimate the prevalence of spine and feet deformities among children who are regularly involved in basketball trainings, as well as finding differences in the prevalence of those deformities between children of different gender and age. The study included a total of 64 children, of which 43 were boys and 21 were girls, ages 10-12. All subjects have been regularly participating in basketball trainings for at least one year. Postural disorder is defined as an irregularity in posture of the spine and feet, and it is assessed by visual methods from the front, side and rear side of the body. The prevalence of spinal deformities in our group was 53.13%. The boys had a significantly higher prevalence than girls, 65.1% compared to 28.57% (p=0.006). There was no significant difference in prevalence of spine deformities between children of different ages. The prevalence of feet deformities was 64.06%. There was a statistically significant difference between the sexes, where boys had a significantly greater prevalence of the feet deformities than girls, 83.7% compared to 23.81% (p=0.001). Flat feet were the most common in 10 year old children (85.71%). In conclusion, it can be said that despite regular participation in basketball training, subjects in this study have high prevalence of deformities; especially boys who stand out with the high prevalence of flat feet.

    A preliminary report from our unit previously suggested that diabetic patients on continuous cyclic peritoneal dialysis (CCPD) have higher ultrafiltration (UF) with icodextrin than non-diabetic patients. To confirm this observation, we did a retrospective analysis of our patients (17 diabetic and 23 non-diabetic) who were on stable CCPD prescription using a long-day dwell with icodextrin. We collected daily UF data from these patients' records for 30 days. The two groups showed no significant difference with respect to age, gender, hemoglobin, serum albumin, peritoneal dialysis and icodextrin vintage, peritoneal membrane characteristics, CCPD prescription, and peritoneal and residual renal clearance. The overnight net UF achieved with the cycler with standard glucose dialysate was similar in the two groups (850+/-379 in diabetic vs 713+/-484 ml/day in non-diabetic, P=0.34). However, UF with icodextrin during the day dwell (14.8+/-0.8 h) was significantly higher in diabetics than non-diabetics (348+/-198 vs 137+/-311 ml/day, P=0.02). Our results show that icodextrin produces significantly higher UF in long-day dwell in diabetic ESRD patients on CCPD than in non-diabetic patients. The reason for this difference is not clear.

    Patients with diabetes mellitus often suffer from diabetic foot syndrome, a condition leading to foot ulceration or even amputation of lower extremity. Peripheral neuropathy combined with repetitive trauma to the foot and peripheral vascular disease are the main etiological factors in the development of foot ulcers. Other major contributive factors include the effects of callus, increased plantar pressures, and local infections. Patient education concerning their disease has a central role in the prevention of foot ulcers. Ordinary preventive measures taken by the patient include regular self-inspections, appropriate daily hygiene of the feet, appropriate footwear to reduce plantar pressures, and medical pedicure performed by a pedicurist experienced in diabetic foot patients. The importance of callus in diabetic patients has been shown in several studies by high predictability of subsequent ulcer development in patients with plantar calluses. For removing callus, urea based preparations are considered to be the treatment of choice. In case of local bacterial and fungal diabetic foot infections, systemic antibiotic and systemic antimycotic therapy is indicated, respectively. Wound dressings of various types are the mainstay in the treatment of chronic foot ulcers with avoidance of occlusive dressings in infected ulcers. Since the vast majority of ulcers and amputations can be prevented in diabetic patients, proper diagnosis and multidisciplinary approach are essential.

    Oxidative stress is suggested to have an important role in the development of complications in diabetes. Because ozone therapy can activate the antioxidant system, influencing the level of glycemia and some markers of endothelial cell damage, the aim of this study was to investigate the therapeutic efficacy of ozone in the treatment of patients with type 2 diabetes and diabetic feet and to compare ozone with antibiotic therapy. A randomized controlled clinical trial was performed with 101 patients divided into two groups: one (n = 52) treated with ozone (local and rectal insufflation of the gas) and the other (n = 49) treated with topical and systemic antibiotics. The efficacy of the treatments was evaluated by comparing the glycemic index, the area and perimeter of the lesions and biochemical markers of oxidative stress and endothelial damage in both groups after 20 days of treatment. Ozone treatment improved glycemic control, prevented oxidative stress, normalized levels of organic peroxides, and activated superoxide dismutase. The pharmacodynamic effect of ozone in the treatment of patients with neuroinfectious diabetic foot can be ascribed to the possibility of it being a superoxide scavenger. Superoxide is considered a link between the four metabolic routes associated with diabetes pathology and its complications. Furthermore, the healing of the lesions improved, resulting in fewer amputations than in control group. There were no side effects. These results show that medical ozone treatment could be an alternative therapy in the treatment of diabetes and its complications.

    Thalassemia is a group of disorders characterized by deficient production of the β-globin sub unit of hemoglobin. The mandatory blood transfusions in patients with thalassemia to maintain adequate erythrocyte levels, leads to iron overload. The prevalence of diabetes in patients with thalassemia varies from 6 to 14%. We here by present a known case of thalassemia major in an 18 year old boy. He was diagnosed with thalassemia before the age of one year and is on regular blood transfusion every two weeks since then. The repeated blood transfusion is one of the common causes for haemochromatosis. Iron overload initially leads to glucose abnormalities such as insulin resistance and hyperinsulinemia, which is followed by impaired secretion of insulin. Diagnosed as a case of bronze diabetes, this patient is on insulin therapy for the last two years. Currently the patient is on iron chelation therapy at Kasturba Medical College Hospital, Mangalore, Karnataka, India.

    A 31-year-old woman with advanced diabetes mellitus with secondary autonomic and peripheral neuropathy was admitted for treatment of major depression. Previous therapy with desipramine resulted in exacerbation of the patient's orthostatic hypotension. After admission to the psychiatric facility she was initially stabilized medically and treated with psychotherapy. Subsequent treatment with low-dose fluoxetine 5 mg resulted in a decrease of the patient's diabetic neuropathy pain. Further increases in the fluoxetine dosage resulted in improvement of her depression and increased pain relief. Therapy with fluoxetine did not result in exacerbation of the orthostatic hypotension. This preliminary case report indicates that fluoxetine may be an alternative to the tricyclic antidepressants and trazodone in the treatment of diabetic peripheral neuropathy.

    2013-01-01

    Flat arches in children usually become proper arches and high arches as the child progresses through adolescence and into adulthood. Only if the deformity persists or presents in adolescence or adulthood is it considered abnormal. We sought to determine the incidence of flatfoot in schoolchildren and to make an anthropometric comparison between flat and normal feet with respect to age and sex in the Hausa ethnic group of Nigeria. Two hundred 9- to 14-year-old students (100 boys and 100 girls) were studied. Navicular height, medial malleolar height, lateral malleolar height, foot length, and transverse arch length were measured with a ruler, marker, and measuring tape. Statistical analysis was conducted using analysis of variance and independent-samples t tests (P ethnic group, with the incidence decreasing with age. Girls had a higher incidence of flatfoot than boys, and it was also influenced by age.

    2012-02-01

    Full Text Available Introduction: Foot infections are one of the major complications of diabetes mellitus and a significant risk factor for lower extremity amputation. Providing effective antimicrobial therapy is an important component in treating these infections. This study assesses the microbial isolates of patients with diabetic foot infections and their antibiotic susceptibility pattern. Materials and Methods: A retrospective study of 75 patients with diabetic foot infections admitted to RIPAS hospital between June 2008 and June 2010 was undertaken. Bacteriological specimens were obtained and processed using standard hospital procedure for microbiological culture and sensitivity testing. Results: Overall, 40 (54% patients had subcutaneous infections, 22 (29% had infected superficial ulcers, seven (9% had infected deep ulcers involving muscle tissues and six (8% had osteomyelitis. A total of 98 pathogens were isolated. Forty percent of the patients had polymicrobial infection, 39 (52% had single organism and 6(8% had no growth. Gram-negative bacteria (67% were more commonly isolated than gram-positive bacteria (30%. The three most frequently found gram-negative organisms were Pseudomonas aeruginosa (19.4%, Klebsiella pneumoniae (15.3%, and Acinetobacter spp. (10.2% and gram-positive organisms were Staphylococcus aureus (10.2%, Streptococcus pyogenes (7.1% and Methicillin resistant Staphylococcus aureus [MRSA] (7.1%. Vancomycin was found to be the most effective against gram-positive bacteria while amikacin was the most effective against gram-negative bacteria based on antibiotic testing. Conclusion: In 40% of diabetic feet infection was polymicrobial. Staphylococcus aureus and Pseudomonas aeruginosa were the most common gram-positive and gram-negative organisms respectively. This study helps us to choose the empirical antibiotics for cases of diabetic foot infections.

  14. Minute synovial sarcomas of the hands and feet: a clinicopathologic study of 21 tumors less than 1 cm.

    Synovial sarcoma, one of the most common types of soft tissue sarcomas, usually presents in the proximal or middle portions of the extremities, often as a large mass with an aggressive clinical behavior. Gland-forming biphasic and spindle cell fibrous monophasic tumors are the most common subtypes. In this study, we evaluated 21 minute synovial sarcomas, hands and feet. These tumors occurred in 14 females and 7 males with a median age of 29 years (range, 8-60 years). Clinically, all tumors were thought to be benign processes such as a ganglion cyst or glomus tumor, and on microscopic examination, they were also often initially misinterpreted as benign lesions such as nerve sheath or (myo) fibroblastic tumors. Histologically, 7 tumors were biphasic and 14 were monophasic spindle cell variants. Microscopic calcifications were present in 8 cases and were prominent in 3 tumors. All monophasic tumors tested had elements positive for EMA, and all but one had reactivity for a keratin cocktail. S-100 protein-positive neuroma-like neural proliferations were commonly present in the monophasic but not in biphasic tumors. SYT-SSX fusion transcripts were demonstrated in 5 cases studied by polymerase chain reaction assay. All tumors were enucleated, followed by local reexcision of the site, and often combined with postoperative radiation. Three patients had amputation of the involved digit or metatarsal. Four patients had local recurrences, 2 of which were successfully treated; 2 of these patients were lost to follow-up. Despite some variation in treatment, all 12 patients with complete follow-up were alive and well, 2 to 32.2 years after surgery (median, 14.7 years), including 2 patients who received neither amputation nor postoperative radiation. Minute synovial sarcomas of hands and feet are clinically favorable tumors if completely excised; there is some evidence to suggest that they may be managed more conservatively than larger tumors. These tumors should be recognized as

  15. The influence of foot orthoses on foot mobility magnitude and arch height index in adults with flexible flat feet.

    Flexible flat foot is described as a reduction in the height of the medial longitudinal arch and may occur from abnormal foot pronation. A foot orthosis is thought to modify and control excessive pronation and improve arch height. To compare the immediate effect of three types of orthoses on foot mobility and the arch height index in subjects with flexible flat feet. A quasi-experimental study. The dorsal arch height, midfoot width, foot mobility and arch height index were assessed in 20 participants with flexible flat feet (mean age = 23.2 ± 3 years) for three different foot orthosis conditions: soft, semi-rigid and rigid University of California Biomechanics Laboratory (UCBL). Maximum midfoot width at 90% with arch mobility in the coronal plane was shown in the semi-rigid orthosis condition. The semi-rigid orthosis resulted in the highest mean foot mobility in 90% of weight bearing, and the rigid orthosis (UCBL) had the lowest mean foot mobility. The soft orthosis resulted in foot mobility between that of the rigid and the semi-rigid orthosis. UCBL orthosis showed the highest arch height index, and the semi-rigid orthosis showed the lowest mean arch height index. Due to its rigid structure and long medial-lateral walls, the UCBL orthosis appears to limit foot mobility. Therefore, it is necessary to make an orthosis that facilitates foot mobility in the normal range of the foot arch. Future studies should address the dynamic mobility of the foot with using various types of foot orthoses. Although there are many studies focussed on flat foot and the use of foot orthoses, the mechanism of action is still unclear. This study explored foot mobility and the influence of foot orthoses and showed that a more rigid foot orthosis should be selected based on foot mobility. © The International Society for Prosthetics and Orthotics 2014.

    Smith, Howard S; Argoff, Charles E

    2011-03-26

    Neuropathic pain continues to be a difficult and challenging clinical issue to deal with effectively. Painful diabetic polyneuropathy is a complex pain condition that occurs with reasonable frequency in the population and it may be extremely difficult for clinicians to provide patients with effective analgesia. Chronic neuropathic pain may occur in approximately one of every four diabetic patients. The pain may be described as burning or a deep-seated ache with sporadic paroxysms of lancinating painful exacerbations. The pain is often constant, moderate to severe in intensity, usually primarily involves the feet and generally tends to worsen at night. Treatment may be multimodal but largely involves pharmacological approaches. Pharmacological therapeutic options include antidepressants (tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors), α2δ ligands and topical (5%) lidocaine patch. Other agents may be different antiepileptic drugs (carbamazepine, lamotrigine, topiramate), topical capsaicin, tramadol and other opioids. Progress continues with respect to understanding various mechanisms that may contribute to painful diabetic neuropathy. Agents that may hold some promise include neurotrophic factors, growth factors, immunomodulators, gene therapy and poly (adenosine diphosphate-ribose) polymerase inhibitors. It is hoped that in the future clinicians will be able to assess patient pathophysiology, which may help them to match optimal therapeutic agents to target individual patient aberrant mechanisms.

  17. The Helios Prototype aircraft at approximately 10,000 feet flying above cloud cover northwest of Kau

    2001-01-01

    As a follow-on to the Centurion (and earlier Pathfinder and Pathfinder-Plus) aircraft, the solar-powered Helios Prototype is the latest and largest example of a slow-flying ultralight flying wing designed for long-duration, high-altitude Earth science or telecommunications relay missions in the stratosphere. Developed by AeroVironment, Inc., of Monrovia, California, under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project, the unique craft is intended to demonstrate two key missions: the ability to reach and sustain horizontal flight at 100,000 feet altitude on a single-day flight in 2001, and to maintain flight above 50,000 feet altitude for at least four days in 2003, with the aid of a regenerative fuel cell-based energy storage system now in development. Both of these missions will be powered by electricity derived from non-polluting solar energy. The Helios Prototype is an enlarged version of the Centurion flying wing, which flew a series of test flights at NASA's Dryden Flight Research Center in late 1998. The craft has a wingspan of 247 feet, 41 feet greater than the Centurion, 2 1/2 times that of its solar-powered Pathfinder flying wing, and longer than the wingspans of either the Boeing 747 jetliner or Lockheed C-5 transport aircraft. The remotely piloted, electrically powered Helios Prototype went aloft on its maiden low-altitude checkout flight Sept. 8, 1999, over Rogers Dry Lake adjacent to NASA's Dryden Flight Research Center in the Southern California desert. The initial flight series was flown on battery power as a risk-reduction measure. In all, six flights were flown in the Helios Protoype's initial development series. In upgrading the Centurion to the Helios Prototype configuration, AeroVironment added a sixth wing section and a fifth landing gear pod, among other improvements. The additional wingspan increased the area available for installation of solar cells and improved aerodynamic efficiency, allowing the Helios

    2017-05-01

    The precision medicine approach of tailoring treatment to the individual characteristics of each patient or subgroup has been a great success in monogenic diabetes subtypes, MODY and neonatal diabetes. This review examines what has led to the success of a precision medicine approach in monogenic diabetes (precision diabetes) and outlines possible implications for type 2 diabetes. For monogenic diabetes, the molecular genetics can define discrete aetiological subtypes that have profound implications on diabetes treatment and can predict future development of associated clinical features, allowing early preventative or supportive treatment. In contrast, type 2 diabetes has overlapping polygenic susceptibility and underlying aetiologies, making it difficult to define discrete clinical subtypes with a dramatic implication for treatment. The implementation of precision medicine in neonatal diabetes was simple and rapid as it was based on single clinical criteria (diagnosed precision diabetes approach in type 2 diabetes will require simple, quick, easily accessible stratification that is based on a combination of routine clinical data, rather than relying on newer technologies. Analysing existing clinical data from routine clinical practice and trials may provide early success for precision medicine in type 2 diabetes.

  4. [The diabetic foot--state of the art from the orthopedic point of view].

    Science.gov (United States)

    Schaefer, D

    1999-07-08

    A 15-30% rate of amputation of diabetic feet suggests that efforts have to be directed towards improvement of preventive measure including instruction of patients and relatives concerning foot wear. So called foot rules have been established. If surgery is indicated, an angiological and neurological assessment should be performed preoperatively. An ulcer should undergo debridement, plantar pressure release with a full contact cast and antibiotic therapy, if infected. The goal of treatment of Charcot's disease is prevention of deformity. Usually orthoses are sufficient, in irreducible deformities an arthrodesis should be considered. There is no doubt that the interdisciplinary approach improves the treatment of the diabetic foot.

    This cross-sectional observational study is to reveal what kind of gait feature is relevant to elevated segment and its plantar pressure for prevention of diabetic foot ulcers. In 57 diabetic patients, the relationship between elevated plantar pressure and gait features was analyzed. To conduct this investigation, a simultaneous measurement system of plantar pressure and gait features was constructed. Plantar pressure distribution was measured by F-scan with customized footwear, and gait features were mainly measured using wireless motion sensors attached to the sacrum and feet. Several gait features of small rolling during the mid-stance phase were relevant to the elevated plantar pressure.

    Bullosis diabeticorum is considered a rare skin manifestation of diabetes mellitus. Tense blisters appear rapidly, mostly on the feet, the cause of which is unclear, with multiple pathophysiologies hypothesised. This is a retrospective review of 4 diabetic patients who presented over six months with diabetic bullae; the condition may therefore not be as rare as commonly believed. All the patients had early surgical debridement followed by topical negative pressure wound dressings. A multidisciplinary team that included vascular surgeons, diabetologists, diabetic foot care team, wound care team, physiotherapists and occupational therapists managed the patients and none of them required amputations. We propose an alternative way of managing these patients with early surgical debridement followed by topical negative pressure wound dressing.

    Full Text Available Abstract: According to TURDEP-II study, the prevalence of diabetes has reached 13.7% in Turkey. Diabetes mellitus is rapidly increasing, and diabetic patients are likely to undergo surgical procedures more than non-diabetic patients. Observational and prospective studies have demonstrated that hyperglycemia correlates with increased morbidity and mortality associated with surgery. Stress hormones such as epinephrine, norepinephrine, cortisol, glucagon, and growth hormone are mostly augmented, and insulin resistance develops during surgery. All diabetic patients undergoing surgery should have comprehensive preoperative evaluation due to the risk of both hypoglycemia and hyperglycemia during surgical procedures. In this article we aimed to review the diabetes treatment protocols for preoperative and postoperative assessment of adult diabetic patients undergoing surgery.

    Full Text Available The purpose of this study was to identify the knowledge, attitudes and practices for the prevention of diabetic foot in patients with diabetes mellitus type 2. This study was based on a cross-sectional survey conducted in two Family Health Units, in the city of Picos - PI, Brazil, with 85 diabetics of both sexes, by means of a semi-structured Knowledge, Attitude and Practice questionnaire. There was a predominance of females in the study (62.4%. On the topic of foot care, 49.4% had no knowledge on hygiene or what to observe in their feet. In relation to nail care, 56.5% were unaware of the correct way to cut nails. Regarding attitudes, 80% were willing to engage in self-care. In terms of practice, results showed that activities such as washing, drying, moisturizing and massaging were not executed together. It is therefore necessary to develop educational strategies to create awareness, both for diabetics and health professionals, on the effective prevention of diabetic foot.

    Diabetic dyschromatopsia is frequent and is a true complication of diabetes mellitus. Causative factors other than retinopathy have been suggested, but they remain unclear. We have explored the color vision of 100 diabetics aged 16 to 65 (88 insulin-dependent, 12 non-insulin dependent) with Lanthony's D15 desatured panel. Degenerative complications were looked for, especially by fundoscopy and electrophysiological exploration of peripheral nerves using specific scoring. 73% of the diabetics had dyschromatopsia. Dyschromatopsia was significatively more frequent when retinopathy was present (26 out of 30 diabetics with retinopathy versus 47/70 without). We explain the absence of a strict parallelism between dyschromatopsia and retinopathy by the intervention of other factors. Whereas the equilibration of the diabetes was not different between the groups with or without dyschromatopsia, patient age, microalbuminuria, blood pressure and alcohol intake were higher in patients with dyschromatopsia. The greater prevalence of peripheral neuropathy in patients with dyschromatopsia, confirmed by electrophysiology, and independently from the existence of retinopathy, is an indicator of the existence of neuronal disease, whose level remains to be determined. Our results are the indispensible preliminary step to a study of the respective importance of these pathogenic factors.

    The preliminary breakdown phase of a negative cloud-to-ground lightning flash was observed in detail. Observations were made with a Photron SA1.1 high-speed video camera operating at 9,000 frames per second, fast optical sensors, a flat-plate electric field antenna covering the SLF to MF band, and VHF and UHF radio receivers with bandwidths of 20 MHz. Bright stepwise extensions of a negative leader were observed at an altitude of 8 km during the first few milliseconds of the flash, and were coincident with bipolar electric field pulses called 'characteristic pulses'. The 2-D step lengths of the preliminary processes were in excess of 100 meters, with some 2-D step lengths in excess of 200 meters. Smaller and shorter unipolar electric field pulses were superposed onto the bipolar electric field pulses, and were coincident with VHF and UHF radio pulses. After a few milliseconds, the emerging negative stepped leader system showed a marked decrease in luminosity, step length, and propagation velocity. Details of these events will be discussed, including the possibility that the preliminary breakdown phase consists not of a single developing lightning leader system, but of multiple smaller lightning leader systems that eventually join together into a single system.

    Full Text Available To achieve high walking stability for a passive dynamic walking robot is not easy. In this article, we aim to investigate whether the walking performance for a passive dynamic walking robot can be improved by just simply changing the swing ankle angle before impact. To validate this idea, a passive bipedal walking model with two straight legs, two flat feet, a hip joint, and two ankle joints was built in this study. The walking dynamics that contains double stance phase was derived. By numerical simulation of the walking in MATLAB, we found that the walking performance can be adjusted effectively by only simply changing the swing ankle angle before impact. A bigger swing ankle angle in a reasonable range will lead to a higher walking stability and a lower initial walking speed of the next step. A bigger swing ankle angle before impact leads to a bigger amount of energy lost during impact for the quasi-passive dynamic walking robot which will influence the walking stability of the next step.

  8. Experimental Investigation of Two Low-Drag Supercavitating Hydrofoils at Speeds up to 200 Feet per Second

    Christopher, Kenneth W.; Johnson, Virgil E., Jr.

    1960-01-01

    An experimental investigation has been made in the Langley highspeed hydrodynamics facility to determine the force and moment characteristics of two hydrofoils (one having an aspect ratio of 1 and the other having an aspect ratio of 3) designed to have improved lift-drag ratios when operating under either supercavitating or ventilated conditions. Measurements were made of lift, drag, and pitching moment over a range of angles of attack from 40 to 200 for depths of submersion varying from 0 to approximately 1 chord. The range of speed for the investigation was from 110 to 200 feet per second. When the upper surface of the hydrofoils was completely unwetted, the experimental values of lift and drag forces were in good agreement with the theoretical values obtained from the zero-cavitation-number theory. The theoretical values for minimum angle of attack for operation with the upper surface of the hydrofoil unwetted define the lower limits of angle of attack for which the experimental values of lift coefficient are either in agreement with or slightly greater than those predicted by theory.

  9. Comparison of bacterial DNA profiles of footwear insoles and soles of feet for the forensic discrimination of footwear owners.

    It is crucial to identify the owner of unattended footwear left at a crime scene. However, retrieving enough DNA for DNA profiling from the owner's foot skin (plantar skin) cells from inside the footwear is often unsuccessful. This is sometimes because footwear that is used on a daily basis contains an abundance of bacteria that degrade DNA. Further, numerous other factors related to the inside of the shoe, such as high humidity and temperature, can encourage bacterial growth inside the footwear and enhance DNA degradation. This project sought to determine if bacteria from inside footwear could be used for footwear trace evidence. The plantar skins and insoles of shoes of volunteers were swabbed for bacteria, and their bacterial community profiles were compared using bacterial 16S rRNA terminal restriction fragment length polymorphism analysis. Sufficient bacteria were recovered from both footwear insoles and the plantar skins of the volunteers. The profiling identified that each volunteer's plantar skins harbored unique bacterial communities, as did the individuals' footwear insoles. In most cases, a significant similarity in the bacterial community was identified for the matched foot/insole swabs from each volunteer, as compared with those profiles from different volunteers. These observations indicate the probability to discriminate the owner of footwear by comparing the microbial DNA fingerprint from inside footwear with that of the skin from the soles of the feet of the suspected owner. This novel strategy will offer auxiliary forensic footwear evidence for human DNA identification, although further investigations into this technique are required.

    To quantify the density of primary epidermal laminae (PELs) around the solar circumference and evaluate the relationship between regional PEL density and hoof capsule morphology in horses. Forefeet from nine 3-year-old Quarter Horse cadavers. Data pertaining to gross features of hoof morphology and PEL variables, including number, density, and distribution patterns around the perimeter of the hoof wall and number of bar PELs, were collected. Tissues of the laminar junction were examined histologically. No significant differences were found between left and right forefeet with respect to gross hoof morphologic measurements. Mean +/- SD number of PELs, including those at the bars of the hoof, was 551 +/- 30. Primary epidermal laminar density in the toe was significantly higher, compared with that in the quarter and heel regions, and was higher on the lateral aspect of the foot, compared with the medial aspect. Feet were significantly wider on the lateral aspect of the foot, compared with the medial aspect, as measured across the widest point of the solar surface. Histologic examination revealed atypical laminar morphology at the toe. Variations were detected in PEL density and morphology around the solar circumference of hooves from 3-year-old racing Quarter Horses. A better understanding of relationships between laminar density, laminar morphology, and gross morphology of the hoof capsule in different populations of horses may aid practitioners in diagnosis and treatment of disease involving the hoof wall in horses.

    The care of combatants with lesions caused by frostbite during the battle of Teruel, which was fought in extreme weather conditions and in temperatures as low as twenty degrees below zero, was the period of greatest medical activity and the highest rates of occupation in the military hospitals of Navarre during the civil war of 1936-1939. From November 1937 to March 1938, 375 cases of frostbite were registered in the provincial establishments, amongst which there was a predominance of cases of dry gangrene partially affecting the lower extremity, which was popularly known as "Teruel feet". Some of the medical staff, conscious of the exceptional nature of the casuistry, registered statistics, clinical cases and personal impressions of the evolution of the lesions and the effectiveness of the treatments. In treating this affectation they employed medicines, surgical techniques and novel therapeutic procedures that were not widely used in the medical milieu of the time. However, the limited duration of the problem, the inconclusive results of the treatments and the differing opinions on their effectiveness -questions that are considered in this article- restricted the subsequent medical repercussion of the experiences of frostbite developed during the wartime period in Teruel.

Most studies, however, compared experts with nonexperts; hence it is, specifically for sports, unclear whether the neuroplastic adaptations reported are sport-specific or sport-general. Here we aimed at investigating sport-specific adaptations in professional handball players and ballet dancers by focusing on the primary motor and somatosensory grey matter (GM representation of hands and feet using voxel-based morphometry as well as on fractional anisotropy (FA of the corticospinal tract by means of diffusion tensor imaging-based fibre tractography.

Compared to handball players, ballet dancers showed decreased FA in both fibres connecting the foot and hand areas, but they showed lower FA in fibres connecting the foot compared to their hand areas, whereas handball players showed lower FA in fibres connecting the hand compared to their foot areas. Our results suggest that structural adaptations are sport-specific and are manifested in brain regions associated with the neural processing of sport-specific skills. We believe this enriches the plasticity research in general and extends our knowledge of sport expertise in particular.

    Flapping, gliding, running, crawling and swimming have all been studied extensively in the past and have served as a source of inspiration for engineering designs. In the current project, we explore a mode of locomotion that straddles ground and air: jumping. The subject of our study is among the most proficient of long-jumpers in Nature: the spider cricket of the family Rhaphidophoridae, which can jump more than 60 times its body length. Despite jumping this immense distance, these crickets usually land on their feet, indicating an ability to control their posture during ``flight.'' We employ high-speed videogrammetry, to examine the jumps and to track the crickets' posture and appendage orientation throughout their jumps. Simple aerodynamic models are developed to predict the aerodynamic forces and moment on the crickets during `flight`. The analysis shows that these wingless insects employ carefully controlled and coordinated positioning of the limbs during flight so as to increase jump distance and to stabilize body posture during flight. The principles distilled from this study could serve as an inspiration for small jumping robots that can traverse complex terrains.

    Diabetes is the most common cause of non-traumatic lower limb amputations and cardiovascular diseases. However, only a negligible percentage of the patients and subjects knew that the feet are affected in diabetes and diabetes affects the heart. Hence, a cross-sectional study was carried out to evaluate the knowledge of diabetes mellitus among the public of different age group, gender, ethnicity, and education level. A sample of 400 participants was randomly selected and data was collected using a structured questionnaire under non-contrived setting. The results showed that there is a statistically significant difference in knowledge on diabetes mellitus among different age groups and different ethnic origin but there is no significant difference in the knowledge among different gender and education level. Out of 400 respondents, 284 respondents (71%) knew that diabetes mellitus is actually a condition characterized by raised blood sugar. Age and education level of respondents were found to be the predominant predictive factors on diabetes knowledge, whereas the gender of respondents did not affect the findings of this study. An improved and well-structured educational programme that tackles the areas of weaknesses should be recommended to increase the level of knowledge on diabetes among Malaysians.

  20. Diabetic foot--what can we learn from leprosy? Legacy of Dr Paul W. Brand.

    2012-02-01

    Leprosy and diabetes, though two very different conditions, may both result in severe loss of sensation in the feet, which are then a great risk of painless injury and ulceration. Seminal observations made by the late Dr Paul W. Brand, a surgeon working with leprosy patients in South India in the mid-20th century, resulted in the subsequent development of treatments to manage insensitive foot ulcers that are today entirely applicable to patients with diabetes. As a consequence of his research, the recognition of the relationship between insensitivity, repetitive pressures and skin breakdown has helped our understanding of the aetiopathogenesis of neuropathic foot lesions in diabetes: the development of the total contact cast and other casting devices to treat such lesions forms the basis of management of diabetic foot lesions with off-loading devices that are widely used in the 21st century in diabetic foot clinics around the world. Moreover, observations by Brand that the foot 'heats up before it breaks down' resulted in more recent research showing that self-skin temperature monitoring might help reduce the incidence of recurrent neuropathic foot ulcers in diabetes. In summary, Brand's understanding of 'the gift of pain' that, when lost, results in the late complications of diabetic neuropathy has guided the prevention, diagnosis and management of diabetic foot problems in the 21st century.

    Full Text Available Background: The burden of diabetes and its foot complications is increasing in India. Prevention of these complications through foot care education should be explored. The objective of our study was to assess the risk factors of poor diabetic foot care and to find the effectiveness of health education in improving foot care practice among diabetes patients. Materials and Methods: A structured pre-tested questionnaire was administered to the outpatients of a rural health center with type 2 diabetes. Awareness regarding diabetes, care of diabetes and foot care practice ware assessed and scored. Individual and group health education focusing on foot care was performed. Foot care practice was reassessed after 2 weeks of education. Results: Only 54% were aware that diabetes could lead to reduced foot sensation and foot ulcers. Nearly 53% and 41% of the patients had good diabetes awareness and good diabetes care respectively. Only 22% of the patients had their feet examined by a health worker or doctor. The patients with poor, satisfactory and good practice scores were 44.7%, 35.9% and 19.4% respectively. Low education status, old age and low awareness regarding diabetes were the risk factors for poor practice of foot care. Average score for practice of foot care improved from 5.90 ± 1.82 to 8.0 ± 1.30 after 2 weeks of health education. Practice related to toe space examination, foot inspection and foot wear inspection improved maximally. Conclusion: Foot care education for diabetics in a primary care setting improves their foot care practice and is likely to be effective in reducing the burden of diabetic foot ulcer.

    Diabetes is one of the most challenging chronic health conditions in the current era. Diabetes-related foot problems need proper patient education, and social media could a play role to disseminate proper information. A systematic search was performed on Facebook groups using the key words "diabetes foot care", "diabetes foot", "diabetes foot management" and "podiatric care". The search resulted in 57 groups and detailed activity information was collected from those groups. Usefulness of each relevant post was determined. Regression analysis was performed to explore the factors associated with the level of usefulness of diabetes foot care-related Facebook groups. Our search resulted in a total of 16 eligible diabetes foot care-related Facebook groups with a total of 103 eligible posts. The average number of group members for the selected groups were 265.75 with an interquartile range of 3.5-107.75. Of the total 103 timeline posts, 45.6% posts were categorized as useful, while the remaining posts were not useful. Top mentioned diabetes foot care practice was "Checking feet daily". Multivariable logistic regression analysis showed that the level of usefulness of diabetes foot care-related Facebook groups were significantly associated with the type of posts and no association was found with presence of "likes" and presence of comment. Facebook being a widely used social networking system, patient welfare organizations, doctors, nurses and podiatrists could use this platform to provide support to educating diabetes patients and their caregivers by disseminating useful and authentic knowledge and information related to diabetes foot care.

    The aim of the study was to discuss the effect of intensive nursing education on the prevention of diabetic foot ulceration among patients at high risk for diabetic foot. One hundred eighty-five diabetes patients at high risk for foot diseases were enrolled in this study and provided with intensive nursing education, including individualized education about diabetes mellitus and diabetic foot diseases, instruction in podiatric care (the right way of washing the foot, the care of foot skin, appropriate choice of shoes and socks, intense examinations and records of feet by patients themselves every day, and the assistant management of calluses). Study subjects were followed up for 2 years. Once the foot ulceration developed, the inducing factors of foot ulceration were inquired about, the ulcers were evaluated, and the incidence of foot ulceration was analyzed before and after the intensive nursing education according to self-paired data. Results showed there were highly statistically significant improvements in the intensive treatment group compared with the control group in plasma glucose, blood pressure, and high-density lipoprotein cholesterol levels. More important is that intensive nursing education helps to prevent diabetic foot ulceration and to decrease the rate of amputation among patients at high risk for diabetic foot.

    Quality improvement depends on data collection and audit of clinical services to inform clinical improvements. Various steps in the care of the diabetic foot can be used to audit a service but need defined audit standards. A diabetes foot service should have risk stratification system in place that should compare to the population-based figures of 76% having low-risk feet, 17% moderate risk and 7% being at high risk of ulceration. Resources can then be directed towards those with high-risk feet. Prevalence of foot ulceration needs to be audited. Community-based studies give an audit standard of around 2%, with 2 to 9% having had an ulcer at some stage in the past. Amputation rates should be easier to measure, and the best results are reported to be around 1.5-3 per 1000 people with diabetes. This is a useful benchmark figure, and the rate has been shown to decrease by approximately a third over the last 15 years in some centres. Ulceration rates and ulcer healing rates are the ultimate outcome audit measure as they are always undesirable, whilst occasionally for defined individuals, an amputation can be a good outcome. In addition to clinical outcomes, processes of care can be audited such as provision of clinical services, time from new ulcer to be seen by health care professional, inpatient foot care or use of antibiotics. Measurement of clinical services can be a challenge in the diabetic foot, but it is essential if clinical services and patient outcomes are to be improved.

    BACKGROUND: The combination of diabetes and hypertension increases the chances of progressive renal disorder and, ultimately, renal failure. Roughly 40% of all diabetics, whether insulin-dependent or not, develop diabetic nephropathy. Diabetic nephropathy is the single most important cause of end......-stage renal disease in the Western world and accounts for more than a quarter of all end-stage renal diseases. Diabetic nephropathy is a major cause of increased morbidity and mortality in diabetic patients. Increased arterial blood pressure is an early and common phenomenon in incipient and overt diabetic...... nephropathy. The relationship between arterial blood pressure and diabetic nephropathy is a complex one, with diabetic nephropathy increasing blood pressure and blood pressure accelerating the course of nephropathy. OVERVIEW: Calcium antagonists antagonize preglomerular vasoconstriction. Additional putative...

    The prosthetic foot plays an important role in propelling, breaking, balancing and supporting body loads while the amputee ambulates on different grounds. It is therefore important to quantify the effect of the prosthetic foot mechanism on biomechanical parameters, in order to prevent pressure ulcers and deep tissue injury. Our aim was to monitor the internal stresses in the residuum of transtibial amputation (TTA) prosthetic-users ambulating on different terrains, which the amputees encounter during their daily activities, i.e. paved floor, grass, ascending and descending stairs and slope. We specifically aimed to compare between the internal stresses in the TTA residuum of amputees ambulating with a novel hydraulic prosthetic foot compared to conventional energy storage and return (ESR) prosthetic feet. Monitoring of internal stresses was accomplished using a portable subject-specific real-time internal stress monitor. We found significant decrease (phydraulic foot, compared to walking with ESR feet. The loading rate calculated while ambulating with the hydraulic foot was at least three times lower than the loading rate calculated while ambulating with the ESR foot. Although the average decrease in internal stresses was ≈ 2-fold larger when replacing single-toe ESR feet with the hydraulic foot than when replacing split-toed ESR feet with the hydraulic foot, the differences were statistically insignificant. Our findings suggest that using a hydraulic prosthetic foot may protect the distal tibial end of the TTA residuum from high stresses, therefore preventing pressure-related injury and pain.

    Diabetic foot neuropathy (DFN) is one of the most important complications of diabetes mellitus; its early diagnosis and intervention can prevent foot ulcers and the need for amputation. Thermometry, measuring the temperature of the feet, is a promising emerging modality for diabetic foot ulcer prevention. However, patient compliance with at-home monitoring is concerning. Delivering messages to remind patients to perform thermometry and foot care might be helpful to guarantee regular foot monitoring. This trial was designed to compare the incidence of diabetic foot ulcers (DFUs) between participants who receive thermometry alone and those who receive thermometry as well as mHealth (SMS and voice messaging) over a year-long study period. This is an evaluator-blinded, randomized, 12-month trial. Individuals with a diagnosis of type 2 diabetes mellitus, aged between 18-80 years, having a present dorsalis pedis pulse in both feet, are in risk group 2 or 3 using the diabetic foot risk classification system (as specified by the International Working Group on the Diabetic Foot), have an operating cell phone or a caregiver with an operating cell phone, and have the ability to provide informed consent will be eligible to participate in the study. Recruitment will be performed in diabetes outpatient clinics at two Ministry of Health tertiary hospitals in Lima, Peru. participants in both groups will receive education about foot care at the beginning of the study and they will be provided with a thermometry device (TempStat™). TempStat™ is a tool that captures a thermal image of the feet, which, depending on the temperature of the feet, shows different colors. In this study, if a participant notes a single yellow image or variance between one foot and the contralateral foot, they will be prompted to notify a nurse to evaluate their activity within the previous 2 weeks and make appropriate recommendations. In addition to thermometry, participants in the intervention arm

    Diabetes mellitus is the commonest cause of an autonomic neuropathy in the developed world. Diabetic autonomic neuropathy causes a constellation of symptoms and signs affecting cardiovascular, urogenital, gastrointestinal, pupillomotor, thermoregulatory, and sudomotor systems. Several discrete syndromes associated with diabetes cause autonomic dysfunction. The most prevalent of these are: generalized diabetic autonomic neuropathy, autonomic neuropathy associated with the prediabetic state, treatment-induced painful and autonomic neuropathy, and transient hypoglycemia-associated autonomic neuropathy. These autonomic manifestations of diabetes are responsible for the most troublesome and disabling features of diabetic peripheral neuropathy and result in a significant proportion of the mortality and morbidity associated with the disease.

    Recent modeling analysis suggests that numerous birds may be at risk of acute poisoning in insecticide-treated fields. Although the majority of avian field studies on pesticides have focused on treated seed, granule, insect or vegetation (oral exposure) ingestion, dermal exposure is an important exposure route when birds come into contact with deposited pesticides on foliage and other surfaces. Some nearctic-neotropical migratory songbirds are likely exposed to pesticides on their non-breeding habitats and include treated crops, plantations or farmlands. In the present study, we developed a method for four environmentally-relevant organophosphate (OP) pesticides (fenthion, fenamiphos, chlorpyrifos and diazinon) in the feet of migratory songbirds (i.e. Common yellowthroat, Gray catbird, Indigo bunting, America redstart, Northern waterthrush, Northern parula, and an additional 12 species of warblers). A total of 190 specimens of the 18 species of songbirds were sampled from available window-killed birds (spring of 2007 and 2011) in downtown Toronto, Canada. The species that were available most likely over-wintered in Mexican/Central American crops such as citrus, coffee and cacao. The feet of the dead birds were sampled and where OP foot exposure likely occurred during over-wintering foraging on pesticide-treated crops. Chlorpyrifos was the only measurable OP (pg mg feet weight(-1)) and in the 2011-collected feet of Black throated blue warbler (0.5), Tennessee warbler (1.0), Northern parula (1.2), Northern waterthrush (0.6), Common yellowthroat (1.0) and the Blue winged warbler (0.9). Dermal contact with OP pesticides during over-wintering in agricultural areas resulted in low levels of chlorpyrifos and long time retention on the feet of a subset of songbirds.

    As more and more prosthetic feet become commercially available, the selection of the appropriate device is a more difficult task for clinical team members. To date, ranking prosthetic feet based on biomechanical parameters has been done using the spring efficiency. The current analytical technique for calculating spring efficiency has two flaws: first, prosthetic feet with a bendable flexible keel are analyzed the same way as those with an articulated ankle and a rigid foot, and second, there is no accounting for the energy losses in the viscoelastic cosmetic material surrounding the keel. This paper develops a rigorous technique to calculate the net energy stored or dissipated and then recovered during the stance phase of gait. Five adults with transtibial amputation were tested with three different prosthetic feet: SACH, Seattle, and Golden-Ankle. The subjects walked at self-selected cadence and stepped on a force plate while two-dimensional segmental kinematic and kinetic data were collected. The results showed that the Golden-Ankle stored or dissipated and then recovered significantly more energy than either the SACH or Seattle. The time to reach foot flat was also significantly reduced for the Golden-Ankle in comparison to both the others. Because the cosmetic material of the SACH foot can store or dissipate and then recover as much energy as the Seattle foot, the SACH foot should be considered an energy-storing foot. Finally, the net efficiency alone can not discriminate adequately among different types of prosthetic feet; therefore, one should consider the time to reach foot flat and the amount of energy recovered as additional objective criteria (weight, maintenance, and cosmesis) for selection of a prosthetic foot device.

    Ruiz Volcano, Colombia (4.88°N, 75.32°W). All times are local (= GMT -5 hours).An explosive eruption on November 13, 1985, melted ice and snow in the summit area, generating lahars that flowed tens of kilometers down flank river valleys, killing more than 20,000 people. This is history's fourth largest single-eruption death toll, behind only Tambora in 1815 (92,000), Krakatau in 1883 (36,000), and Mount Pelée in May 1902 (28,000). The following briefly summarizes the very preliminary and inevitably conflicting information that had been received by press time.
