  1. Heel raises versus prefabricated orthoses in the treatment of posterior heel pain associated with calcaneal apophysitis (Sever's Disease): study protocol for a randomised controlled trial

    PubMed Central

    2010-01-01

    Background Posterior Heel pain can present in children of 8 to 14 years, associated with or clinically diagnosed as Sever's disease, or calcaneal apophysitis. Presently, there are no comparative randomised studies evaluating treatment options for posterior heel pain in children with the clinical diagnosis of calcaneal apophysitis or Sever's disease. This study seeks to compare the clinical efficacy of some currently employed treatment options for the relief of disability and pain associated with posterior heel pain in children. Method Design: Factorial 2 × 2 randomised controlled trial with monthly follow-up for 3 months. Participants: Children with clinically diagnosed posterior heel pain possibly associated with calcaneal apophysitis/Sever's disease (n = 124). Interventions: Treatment factor 1 will be two types of shoe orthoses: a heel raise or prefabricated orthoses. Both of these interventions are widely available, mutually exclusive treatment approaches that are relatively low in cost. Treatment factor 2 will be a footwear prescription/replacement intervention involving a shoe with a firm heel counter, dual density EVA midsole and rear foot control. The alternate condition in this factor is no footwear prescription/replacement, with the participant wearing their current footwear. Outcomes: Oxford Foot and Ankle Questionnaire and the Faces pain scale. Discussion This will be a randomised trial to compare the efficacy of various treatment options for posterior heel pain in children that may be associated with calcaneal apophysitis also known as Sever's disease.

    A 63-year-old woman initially presented with progressive left foot pain for 3 months, not responding to conservative management. MRI of the left foot showed a suspicious lesion in calcaneus. An open biopsy was consistent with metastatic lung adenocarcinoma. Tc-MDP total-body bone scintigraphy was ordered for possible other bony lesions, and only left calcaneus lesion was identified on bone scan. CT scan of the chest revealed a soft tissue mass in the superior aspect of the right lower lobe. Staging FDG PET/CT showed hypermetabolic right lung mass and left calcaneus lesion. She received chemotherapy and local radiation to the left calcaneus metastatic lesion. PMID:26562577

    The capacity of the calcaneal heel pad, with and without augmentation by a polymeric shock absorbing material (Sorbothane 0050), to attenuate heel strike impulses has been studied using five fresh human cadaveric lower leg specimens. The specimens, instrumented with an accelerometer, were suspended and impacted with a hammer; a steel rod was similarly suspended and impacted. The calcaneal heel pad attenuated the peak accelerations by 80%. Attenuations of up to 93% were achieved by the shock absorbing material when tested against the steel rod; however, when tested in series with the calcaneal heel pad, the reduction in peak acceleration due to the shock absorbing material dropped to 18%. Any evaluation of the effectiveness of shock absorbing shoe materials must take into account their mechanical interaction with the body. PMID:8419676

    A rare case of bilateral calcaneal stress fractures in a patient with Diamond-Blackfan anaemia is described. This has not been previously reported in the literature. A calcaneal stress fracture is an important differential diagnosis in a patient presenting with heel pain. Bilaterality of symptoms should not exclude this diagnosis and clinicians should be especially vigilant with predisposed patients. PMID:26004126

    Context: Heel pain, a relatively common problem in the athlete, can present a diagnostic and therapeutic dilemma. The purpose of this article is to review treatment techniques for common causes of heel pain in the athlete. Evidence Acquisition: Articles in the English literature through August 2008 were selected and reviewed in the context of the management of heel pain in the athlete. Clinical and surgical photographs are presented as an illustration of preferred techniques and pertinent pathologic findings. Results: Although nonoperative treatment remains the mainstay for most painful heel pathologies, a number of surgical interventions have shown encouraging results in carefully selected patients. Conclusions: The management of heel pain in the athlete requires diagnostic skill, appropriate imaging evaluation, and a careful, initially conservative approach to treatment. Surgical treatment can be successful in carefully selected patients. PMID:23015903

    Heel pain is a very common foot disease. Varieties of names such as plantar fasciitis, jogger's heel, tennis heal, policeman's heel are used to describe it. Mechanical factors are the most common etiology of heel pain. Common causes of hell pain includes: Plantar Fasciitis, Heel Spur, Sever's Disease, Heel bump, Achilles Tendinopathy, Heel neuritis, Heel bursitis. The diagnosis is mostly based on clinical examination. Normally, the location of the pain and the absence of associated symptoms indicating a systemic disease strongly suggest the diagnosis. Several therapies exist including rest, physical therapy, stretching, and change in footwear, arch supports, orthotics, night splints, anti-inflammatory agents, and surgery. Almost all patients respond to conservative nonsurgical therapy. Surgery is the last treatment option if all other treatments had failed. Rest, ice, massage, the use of correct exercise and complying with a doctor's advice all play important part in helping to recover from this hell pain condition, but getting good quality, suitable shoes with the appropriate amount of support for the whole foot is the most important.

    Heel pain is a common and frequently disabling clinical complaint that may be caused by a broad spectrum of osseous or soft-tissue disorders. These disorders are classified on the basis of anatomic origin and predominant location of heel pain to foster a better understanding of this complaint. The disorders include plantar fascial lesions (fasciitis, rupture, fibromatosis, xanthoma), tendinous lesions (tendinitis, tenosynovitis), osseous lesions (fractures, bone bruises, osteomyelitis, tumors), bursal lesions (retrocalcaneal bursitis, retroachilleal bursitis), tarsal tunnel syndrome, and heel plantar fat pad abnormalities. With its superior soft-tissue contrast resolution and multiplanar capability, magnetic resonance (MR) imaging can help determine the cause of heel pain and help assess the extent and severity of the disease in ambiguous or clinically equivocal cases. Careful analysis of MR imaging findings and correlation of these findings with patient history and findings at physical examination can suggest a specific diagnosis in most cases. The majority of patients with heel pain can be successfully treated conservatively, but in cases requiring surgery (eg, plantar fascia rupture in competitive athletes, deeply infiltrating plantar fibromatosis, masses causing tarsal tunnel syndrome), MR imaging is especially useful in planning surgical treatment by showing the exact location and extent of the lesion.

    Calcaneal fracture patterns vary widely, and many factors determine the type and timing of the treatment rendered. Severe calcaneus fractures involving joint damage, loss of heel height, and varus deformity of the tuberosity are ideally treated with open reduction and internal fixation to repair the joint surface and re-establish anatomic structure. This is not always possible owing to delayed presentation, soft tissue compromise, unrelated injuries, unstable medical condition, or lack of expertise by the treating physician. We present the case of a patient who had residual forefoot and rearfoot deformity despite undergoing delayed subtalar joint arthrodesis at an outside hospital 10 years before for a calcaneal fracture that was initially treated nonoperatively. At 4 years of follow-up after modified Dwyer calcaneal osteotomy with rotation and reinsertion of the autograft bone wedge and Cotton midfoot osteotomy, the postoperative gait was relatively normal, other than the expected lack of hindfoot mobility. The lateral column pain was resolved. The patient remained highly satisfied with the outcome at long-term follow-up of 48 months, with improved heel alignment, lack of a wide stance gait, a functional medial column, and a relatively normal gait. This case demonstrates the value of periarticular calcaneal osteotomies without the need to revise the subtalar joint arthrodesis for this challenging clinical situation. PMID:25217369

    In this study we aimed to determine the role of bone scintigraphy as an objective diagnostic method in patients with heel pain. 67 heels of 50 of 182 patients with defined features who attended the orthopedics outpatient clinic with heel pain over a 3-year period, were treated with combined methods such as nonsteroidal anti-inflammatory drugs (NSAID) and contrast baths, stretching exercises and changing of footwear habits. A one year follow-up was established. The criteria identified by Wolgin et al. were used in assessing the results of the treatment. Subcalcaneal spur was demonstrated by radiography in 44 of the 67 heels. There were two different imaging patterns observed on three phase bone scintigraphy. Type I imaging pattern: Focal increased activity in the heel region or normal activity on dynamic and the blood pool phases and focal increased activity at the inferior calcaneal surface in the late static phase. Type II imaging pattern: Diffuse increased activity along the plantar fascia in the dynamic and the blood pool phase, and focal increased activity at the inferior calcaneal surface in the late static phase. There were 34 (50.7%) type I and 18 (26.8%) type II imaging patterns on the scans. Type I and type II imaging patterns were described as osseous and fascial respectively. At the final examination, the results for pattern type I were good in 16 patients (66.7%), fair in 6 patients (25%) and poor in 2 patients (8.3%), whereas in pattern type II results were good in 12 patients (80%) and fair in 3 patients (20%). The recurrence frequency was 4.1% and 6.6%, respectively. Subcalcaneal spur was determined in 70.5% of the patients with osseous pathology and 55.5% of the patients with fascial pathology. Based on this result, it can be ascertained that calcaneal spurs develop during the pathological process causing heel pain. Other findings supporting this claim were the differences in symptom periods of the patients with type I and type II imaging patterns and scintigraphies were normaly in 10 of 44 heels indicating subcalcaneal spurs on radiographies. These findings suggested that metabolic changes contributing to subcalcaneal spur were complete. Three phase bone scintigraphy is an objective method which can be used to diagnose heel pain, especially when determining the etiological factors and prognosis. PMID:12416578

    The heel fat pad has a unique structure that is important for its shock-absorbing function. Loss of elasticity and changes in the thickness of the heel pad have been suggested as causes of heel pain. The present study of a population with heel pain shows the relationship between the thickness and elasticity of the heel fat pad and age, sex, obesity, duration of symptoms, subcalcaneal spurs, and noninvasive conservative treatment. Of 182 patients with heel pain who visited an outpatient clinic during a 3-year period, 50 (67 heels) fulfilling specific criteria were treated with a combination of nonsteroidal anti-inflammatory drugs, contrast baths, stretching exercises, and change of footwear habits. Patients were followed up for 1 year. Delayed healing, increased thickness, and decreased elasticity of the heel fat pad were found in patients who were older than 40 years, who had symptoms for longer than 12 months before treatment, and who had a large subcalcaneal spur. An increase in heel fat pad thickness with aging and increased body weight reduce the elasticity of the heel fat pad. In addition, subcalcaneal spurs diminish the elasticity of the heel fat pad and play a role in the formation of heel pain. PMID:14729991

    Sever's injury (apophysitis calcanei) is considered to be the dominant cause of heel pain among children between 8 and 15 years. Treating Sever's injury with insoles is often proposed as a part of a traditional mix of recommendations. Using a custom-molded rigid heel cup with a brim enclosing the heel pad resulted in effective pain relief without reducing the physical activity level in our previous two studies. The purpose of this study was to assess the effect of the heel cup on heel pad thickness and heel peak pressure (n=50). The difference in heel pad thickness and in heel peak pressure using a sports shoe without and with a heel cup was compared. With the heel cup the heel pad thickness improved significantly and the heel peak pressure was significantly reduced. These effects correlated with a significant reduction in pain when using the heel cup in a sports shoe, compared with using a sports shoe without the heel cup. A heel cup, providing an effective heel pad support in the sports shoe, improved the heel pad thickness and reduced heel peak pressure in Sever's injury with corresponding pain relief. PMID:21410537

    The majority of plantar heel pain is diagnosed as plantar fasciitis or heel spur syndrome. When history or physical findings are unusual or when routine treatment proves ineffective, one should consider an atypical cause of heel pain. Stress fractures of the calcaneus are a frequently unrecognized source of heel pain. In a normal populatıon, the possibility of calcaneal stress fractures must be borne in mind with patients who have bilateral heel pain. When a stress fracture is considered, clinicans have different imaging options. First of all, x-rays must be used to evaluate for any visible osseous pathology. If plain films are inconclusive, the clinician can proceed with a bone scan or Magnetic Resonance Imaging. In the literature, calcaneal stress fractures are mostly reported in soldiers or athletes, but our case is one of a 44-year-old housewife with bilateral heel pain treated as Achilles tendinitis and plantar faciitis for a long time. Her final diagnosis was bilateral calcaneal fracture by Magnetic Resonance Imaging. PMID:23208939

    In conclusion, horses with heel or navicular area pain vary, and no one treatment option is suitable for all horses. Each horse must be evaluated individually to determine which structure in the palmar aspect of the foot is injured, severity of disease, horse and hoof conformation, and horse use and level of performance expectation before a treatment plan can be developed. Overall, there are many treatment options to help these horses to perform their intended athletic event. PMID:14575167

    A 72-year-old woman was diagnosed with an avulsion fracture of the tuberosity of the calcaneus. The fracture was planned for elective fixation 12 days after the accident. The planned open reduction and internal fixation was not possible due to a decubital wound on the Achilles heel as a result of pressure on the skin of the fractured tuberosity. Closed reduction and internal fixation was performed, leading to an acceptable outcome. Avulsion fractures of the tuberosity of the calcaneus are rare injuries, and delay in treatment should be avoided as it may lead to preventable complications. PMID:26759395

    Background Plantar fasciitis (PF) is a soft tissue disorder considered to be one of the most common causes of inferior heel pain. The aim of this study was to investigate the effect of monophasic pulsed current (MPC) and MPC coupled with plantar fascia-specific stretching exercises (SE) on the treatment of PF. Material/Methods Forty-four participants (22 women and 22 men, with a mean age of 49 years) diagnosed with PF were randomly assigned to receive MPC (n=22) or MPC coupled with plantar fascia-specific SE (n=22). Prior to and after 4 weeks of treatment, participants underwent baseline evaluation; heel pain was evaluated using a visual analogue scale (VAS), heel tenderness threshold was quantified using a handheld pressure algometer (PA), and functional activities level was assessed using the Activities of Daily Living subscale of the Foot and Ankle Ability Measure (ADL/FAAM). Results Heel pain scores showed a significant reduction in both groups compared to baseline VAS scores (P<0.001). Heel tenderness improved significantly in both groups compared with baseline PA scores (P<0.001). Functional activity level improved significantly in both groups compared with baseline (ADL/FAAM) scores (P<0.001). However, no significant differences existed between the 2 treatment groups in all post-intervention outcome measures. Conclusions This trial showed that MPC is useful in treating inferior heel symptoms caused by PF. PMID:25791231

    2011-01-01

    Prompted by repeated pathology reports of fibromas at the origin of the plantar fascia after fasciectomy for chronic plantar heel pain, this study examined the incidence of proximal plantar fibroma. A retrospective study of 100 pathology specimens from 97 patients with the preoperative diagnosis of recalcitrant plantar fasciitis was performed. Patients ranged in age from 36 to 82, and included 31 males and 66 females. The specimens consisted of medial and central bands of the fascia obtained from transverse plantar fasciectomies. The fasciectomies were performed by 4 surgeons between July 1994 and March 2008. One quarter of the cases studied had a histological appearance of plantar fibroma. This new finding has not been reported in any literature in connection with recalcitrant heel pain. Histologic findings of the specimens were placed into 3 groups: neoplastic involvement (25%, 21 female and 6 male), inflammation without neoplastic involvement (21%, 13 female and 6 male), and other, which consisted of having no inflammatory or neoplastic response (54%, 32 female and 19 male). All of the patients ailed a 3- to 6-month conservative treatment regimen, which included anti-inflammatory medication, modification of activities, injection of corticosteroids, night splints, custom molded orthotics, and physical therapy. Only 3 patients underwent bilateral plantar fasciectomies. No patient required a revisional procedure. The authors conclude that 25% of recalcitrant heel pain is neoplastic in origin, and that patients presenting with these lesions require excision and not fasciotomy. PMID:21353998

    Background Plantar heel pain is a common disorder of the foot for which patients seek medical treatment. The purpose of this study is to explore the relationship between duration of symptoms in plantar fasciitis patients and demographic factors, the intensity and location of pain, extent of previous treatment and self reported pain and function. Methods The charts of patients presenting with plantar heel pain between June 2008 and October 2010 were reviewed retrospectively and 182 patients with a primary diagnosis of plantar fasciitis were identified. Patients with symptoms less than 6 months were identified as acute and patients with symptoms greater than or equal to six months were defined as having chronic symptoms. Comparisons based on duration of symptoms were performed for age, gender, BMI, comorbidities, pain location and intensity, and a functional score measured by the Foot and Ankle Ability Measure (FAAM). Results The two groups were similar in age, BMI, gender, and comorbidities. Pain severity, as measured by a VAS, was not statistically significant between the two groups (6.6 and 6.2). The acute and chronic groups of patients reported similar levels of function on both the activity of daily living (62 and 65) and sports (47 and 45) subscales of the FAAM. Patients in the chronic group were more likely to have seen more providers and tried more treatment options for this condition. Conclusion As plantar fasciitis symptoms extend beyond 6 months, patients do not experience increasing pain intensity or functional limitation. No specific risk factors have been identified to indicate a risk of developing chronic symptoms. PMID:22995253

    When the rear- and forefoot are constrained, calcaneal plantar flexion may occur, deforming the longitudinal arch. Previous research has reported calcaneal motion relative to the tibia or forefoot; these joint rotations may not accurately describe rotation of the calcaneus alone. This investigation: (1) characterized the calcaneus and leg segment and ankle joint rotations during stance in gait, and (2) described the range of calcaneal plantar flexion in different structural arch types. Men (n = 14) and women (n = 16) performed gait in a motion analysis laboratory. From heel strike to heel off, the leg rotated forward while the calcaneus plantar flexed. Before foot flat, calcaneal plantar flexion was greater than forward leg rotation, resulting in ankle plantar flexion. After foot flat, forward leg rotation was greater than calcaneal plantar flexion, resulting in ankle dorsiflexion. Structural arch type was classified using the longitudinal arch angle. The range of calcaneal plantar flexion from foot flat to heel off was small in low (-2° to -8°), moderate in high (-3° to -12°), and large in normal (-2° to -20°) structural arches. Calcaneal plantar flexion in gait during midstance may reflect functional arch characteristics, which vary depending on structural arch type. PMID:26398966

    The aim of this study was to compare the effectiveness of extracorporeal shock wave therapy (ESWT) and ultrasound therapy (US) for managing heel pain. Thirty-seven subjects received either: ESWT (once a week), US (three times a week), or CONTROL (no treatment) for 3 consecutive weeks and were followed-up for 3 more weeks. A visual analogue scale (VAS), the maximum tolerable duration for prolonged walking or standing, and the Mayo clinical scoring system (MCSS) were evaluated. Mixed models treating baseline measures as covariates were adopted for statistical analysis. By week 3, intensity of heel pain on palpation was reduced by 37% (VAS score from 7.5 to 4.6) in the ESWT group, 24% (from 5.3 to 4.2) in the US group, and increased by 3% (5.6-5.7) in the control group; this difference was significant after adjusting for baseline VAS scores ( p = 0.022). The improvements in the maximum tolerable duration of prolonged walking or standing was only significant in the ESWT group (157% increase, p = 0.043) but not the other two groups. Both active treatment groups maintained the treatment effect at the three-week follow-up. We conclude that ESWT is potentially more effective in reducing heel pain than ultrasound therapy but additional evidence is needed due to the various limitations of the study.

    Background Plantar heel pain is one of the most common musculoskeletal disorders of the foot and ankle. Treatment of the condition is usually conservative, however the effectiveness of many treatments frequently used in clinical practice, including stretching, has not been established. We performed a participant-blinded randomised trial to assess the effectiveness of calf muscle stretching, a commonly used short-term treatment for plantar heel pain. Methods Ninety-two participants with plantar heel pain were recruited from the general public between April and June 2005. Participants were randomly allocated to an intervention group that were prescribed calf muscle stretches and sham ultrasound (n = 46) or a control group who received sham ultrasound alone (n = 46). The intervention period was two weeks. No participants were lost to follow-up. Primary outcome measures were 'first-step' pain (measured on a 100 mm Visual Analogue Scale) and the Foot Health Status Questionnaire domains of foot pain, foot function and general foot health. Results Both treatment groups improved over the two week period of follow-up but there were no statistically significant differences in improvement between groups for any of the measured outcomes. For example, the mean improvement for 'first-step' pain (0100 mm) was -19.8 mm in the stretching group and -13.2 mm in the control group (adjusted mean difference between groups -7.9 mm; 95% CI -18.3 to 2.6). For foot function (0100 scale), the stretching group improved 16.2 points and the control group improved 8.3 points (adjusted mean difference between groups 7.3; 95% CI -0.1 to 14.8). Ten participants in the stretching group experienced an adverse event, however most events were mild to moderate and short-lived. Conclusion When used for the short-term treatment of plantar heel pain, a two-week stretching program provides no statistically significant benefit in 'first-step' pain, foot pain, foot function or general foot health compared to not stretching.

    Background There is considerable controversy regarding the effectiveness of extracorporeal shock wave therapy in the management of plantar heel pain. Our aim was to conduct a systematic review of randomised controlled trials to investigate the effectiveness of extracorporeal shock wave therapy and to produce a precise estimate of the likely benefits of this therapy. Methods We conducted a systematic review of all randomised controlled trials (RCTs) identified from the Cochrane Controlled trials register, MEDLINE, EMBASE and CINAHL from 1966 until September 2004. We included randomised trials which evaluated extracorporeal shock wave therapy used to treat plantar heel pain. Trials comparing extra corporeal shock wave therapy with placebo or different doses of extra corporeal shock wave therapy were considered for inclusion in the review. We independently applied the inclusion and exclusion criteria to each identified randomised controlled trial, extracted data and assessed the methodological quality of each trial. Results Six RCTs (n = 897) permitted a pooled estimate of effectiveness based on pain scores collected using 10 cm visual analogue scales for morning pain. The estimated weighted mean difference was 0.42 (95% confidence interval 0.02 to 0.83) representing less than 0.5 cm on a visual analogue scale. There was no evidence of heterogeneity and a fixed effects model was used. Conclusion A meta-analysis of data from six randomised-controlled trials that included a total of 897 patients was statistically significant in favour of extracorporeal shock wave therapy for the treatment of plantar heel pain but the effect size was very small. A sensitivity analysis including only high quality trials did not detect a statistically significant effect. PMID:15847689

    Objective To investigate efficacy of a contoured sandal being marketed for plantar heel pain with comparison to a flat flip-flop and contoured in-shoe insert/orthosis. Method 150 volunteers aged 50 (SD: 12) years with plantar heel pain (>4 weeks) were enrolled after responding to advertisements and eligibility determined by telephone and at first visit. Participants were randomly allocated to receive commercially available contoured sandals (n = 49), flat flip-flops (n = 50) or over the counter, pre-fabricated full-length foot orthotics (n = 51). Primary outcomes were a 15-point Global Rating of Change scale (GROC: 1 = a very great deal worse, 15 = a very great deal better), 13 to 15 representing an improvement and the 20-item Lower Extremity Function Scale (LEFS) on which participants rate 20 common weight bearing activities and activities of daily living on a 5-point scale (0 = extreme difficulty, 4 = no difficulty). Secondary outcomes were worst level of heel pain in the preceding week, and the foot and ankle ability measure. Outcomes were collected blind to allocation. Analyses were done on an intention to treat basis with 12 weeks being the primary outcome time of interest. Results The contoured sandal was 68% more likely to report improvement in terms of GROC compared to flat flip-flop. On the LEFS the contoured sandal was 61% more likely than flat flip-flop to report improvement. The secondary outcomes in the main reflected the primary outcomes, and there were no differences between contoured sandal and shoe insert. Conclusions and Relevance Physicians can have confidence in supporting a patient's decision to wear contoured sandals or in-shoe orthoses as one of the first and simple strategies to manage their heel pain.

    The present case illustrates a lipoma as an unusual cause of heel pain. A 64-year-old female ballroom dancer presented with 8 months of pain that was unresponsive to previous treatment of plantar fasciitis. Magnetic resonance imaging revealed a heel lipoma. Her pain was fully resolved after surgical excision. Soft tissue tumors should be included in the differential diagnosis of heel pain, especially when symptoms and treatment response do not follow the typical course of plantar fasciitis. PMID:25624040

    Excessive foot pronation has been associated with the occurrence of low back pain, possibly for generating changes in the lumbopelvic alignment. However, the influence of foot pronation (measured as calcaneal eversion) on pelvic alignment during standing has not been well established. Fourteen young healthy subjects participated in the study. A Motion Analysis System was used to obtain pelvic positions in sagittal and frontal planes and calcaneal position in the frontal plane. Volunteers were filmed in relaxed standing position during three trials, in three conditions: control; unilateral experimental with increased right calcaneal eversion and bilateral experimental with increased bilateral calcaneal eversion. Increased calcaneal eversion was obtained using wedges tilted 10 degrees medially, unilaterally and bilaterally. Repeated measures ANOVAs with Bonferroni corrections were used for statistical analysis. Unilateral and bilateral use of medially tilted wedges produced a significant increase of calcaneal eversion (Pcalcaneal eversion caused average pelvic anteversion of 1.57 degrees (P=0.003) and 1.41 degrees (P=0.021), respectively. Unilaterally increased everted position generated an average pelvic lateral tilt of 1.46 degrees (P<0.001). Excessive calcaneal eversion during standing changes pelvic alignment and should be considered, associated with other relevant factors, when assessing pelvic misalignments. PMID:17910932

  16. Proximally based sural adipose-cutaneous/scar flap in elimination of ulcerous scar soft-tissue defect over the achilles tendon and posterior heel region: a new approach.

    Scar ulcers that spread over the Achilles tendon and posterior heel disturb patients by causing pain, impeding hygiene, and creating difficulty in finding appropriate shoe wear. As this region undergoes pressure, effective reconstruction is based on the flap use. The most popular flaps currently used are distally based sural fasciocutaneous flap, calcaneal artery skin flap, and free flaps. These flaps, however, are insensate, can create soft-tissue excess, and cause donor site morbidity. Ulcerous soft-tissue defects over Achilles tendon and posterior heel after burns, frost, and trauma were studied and reconstructed in 16 patients, using proximally based sural adipose-cutaneous flap, the anatomy of which was studied on lower extremities of 27 cadavers. Ulcerous soft-tissue defect consists of two parts: ulcer and surrounding pathologic scars that should be excised in one block. Resulting soft-tissue defects with exposed tendon and calcaneal bone varied from 6 to 20 cm in length and 6 cm in width. For such wound resurfacing a flap was developed that was sensate, thin, large, and having steady blood circulation. The flap was harvested from the lower third of the leg and lateral foot, consisting of skin and subcutaneous fat layer (without fascia), including the sural nerve and lesser vein. The blood supply was ensured through peroneal and anterior tibial artery perforators, which formed a vascular net in the flap. In 14 of 16 cases excellent and stable functional and good cosmetic results with acceptable donor site morbidity were achieved. In two patients the distal flap loss took place because of arteriitis obliterans (one case) and because of the cross-cutting of the sural nerve and vessels during previous surgeries (another case). Proximally based sural adipose-cutaneous/scar flap is the only flap that satisfies all requirements for Achilles tendon and posterior heel region resurfacing. The author believes that this technique, based on this flap use, is anatomically justified, clinically profitable, and should be considered as the first choice operation. PMID:24043244

  18. Comparison of usual podiatric care and early physical therapy intervention for plantar heel pain: study protocol for a parallel-group randomized clinical trial

    PubMed Central

    2013-01-01

    Background A significant number of individuals suffer from plantar heel pain (PHP) and many go on to have chronic symptoms and continued disability. Persistence of symptoms adds to the economic burden of PHP and cost-effective solutions are needed. Currently, there is a wide variation in treatment, cost, and outcomes of care for PHP with limited information on the cost-effectiveness and comparisons of common treatment approaches. Two practice guidelines and recent evidence of effective physical therapy intervention are available to direct treatment but the timing and influence of physical therapy intervention in the multidisciplinary management of PHP is unclear. The purpose of this investigation is to compare the outcomes and costs associated with early physical therapy intervention (ePT) following initial presentation to podiatry versus usual podiatric care (uPOD) in individuals with PHP. Methods A parallel-group, block-randomized clinical trial will compare ePT and uPOD. Both groups will be seen initially by a podiatrist before allocation to a group that will receive physical therapy intervention consisting primarily of manual therapy, exercise, and modalities, or podiatric care consisting primarily of a stretching handout, medication, injections, and orthotics. Treatment in each group will be directed by practice guidelines and a procedural manual, yet the specific intervention for each participant will be selected by the treating provider. Between-group differences in the Foot and Ankle Ability Measure 6 months following the initial visit will be the primary outcome collected by an independent investigator. In addition, differences in the European Quality of Life – Five Dimensions, Numeric Pain Rating Scale, Global Rating of Change (GROC), health-related costs, and cost-effectiveness at 6 weeks, 6 months, and 1 year will be compared between groups. The association between successful outcomes based on GROC score and participant expectations of recovery generally, and specific to physical therapy and podiatry treatment, will also be analyzed. Discussion This study will be the first pragmatic trial to investigate the clinical outcomes and cost-effectiveness of ePT and uPOD in individuals with PHP. The results will serve to inform clinical practice decisions and management guidelines of multiple disciplines. Trial registration ClinicalTrials.gov: NCT01865734 PMID:24299257

    Chondroblastomas account for <2% of all bone tumors. The calcaneus is the fifth most common location of occurrence. Males in their second decade of life are most often affected, presenting with an insidious onset of localized pain, swelling, and tenderness. The finding of associated pathologic fracture has been rare. Imaging studies can aid in the formulation of the differential diagnosis and surgical plan. The definitive diagnosis requires histologic examination. Curettage and bone grafting is curative in >80% of cases. Local recurrence rates of ≤38% have been reported, most often because of inadequate resection, and have been associated with malignant conversion and metastasis. Adjuvant therapies can help minimize the incidence of local recurrence. Long-term follow-up examinations are recommended, given the protracted interval that can exist between recurrence and the potential for malignant conversion and metastasis. We present the case of a young, healthy, active male with a calcaneal chondroblastoma and associated pathologic fracture whose initial treatment consisted of curettage, hydrogen peroxide lavage, and allogeneic bone grafting. Recurrence developed at 15 months postoperatively and was treated with repeat curettage, high-speed burring, and reconstruction with steel Steinman pins and polymethylmethacrylate, resulting in no pain or recurrence at the 5-month follow-up point.

    Displaced tongue-type fractures of the calcaneus can lead to severe pain and disability if not treated appropriately. Failure to reduce articular displacement may require subtalar joint arthrodesis with subsequent loss of function. The subtalar joint is crucial for normal foot and ankle function. In selected cases, if the malunited joint is still in good condition, it is preserved by corrective osteotomy. A joint-preserving osteotomy with axial realignment is a treatment option for malunited tongue-type calcaneal fractures encountered early on, before the development of subtalar arthrosis in carefully selected patients.

    Purpose: To conduct a randomized trial of radiation therapy for painful heel spur, comparing a standard dose with a very low dose. Methods and Materials: Sixty-six patients were randomized to receive radiation therapy either with a total dose of 6.0 Gy applied in 6 fractions of 1.0 Gy twice weekly (standard dose) or with a total dose of 0.6 Gy applied in 6 fractions of 0.1 Gy twice weekly (low dose). In all patients lateral opposing 4- to 6-MV photon beams were used. The results were measured using a visual analogue scale, the Calcaneodynia score, and the SF12 health survey. The fundamental phase of the study ended after 3 months, and the follow-up was continued up to 1 year. Patients with insufficient pain relief after 3 months were offered reirradiation with the standard dosage at any time afterward. Results: Of 66 patients, 4 were excluded because of withdrawal of consent or screening failures. After 3 months the results in the standard arm were highly significantly superior compared with those in the low-dose arm (visual analogue scale, P=.001; Calcaneodynia score, P=.027; SF12, P=.045). The accrual of patients was stopped at this point. Further evaluation after 12 months' follow-up showed the following results: (1) highly significant fewer patients were reirradiated in the standard arm compared with the low-dose arm (P<.001); (2) the results of patients in the low-dose arm who were reirradiated were identical to those in the standard arm not reirradiated (reirradiation as a salvage therapy if the lower dose was ineffective); (3) patients experiencing a favorable result after 3 months showed this even after 12 months, and some results even improved further between 3 and 12 months. Conclusions: This study confirms the superior analgesic effect of radiation therapy with 6-Gy doses on painful heel spur even for a longer time period of at least 1 year.

    Recurrent ulcerations of the foot and ankle almost always present a challenge to lower extremity surgeons. Recalcitrant heel ulcerations with osteomyelitis are especially difficult to treat because of the lack of soft tissue coverage. The turnover flap is a simple, fast, and effective treatment method for lower extremity wounds. It is a de-epithelialized fasciocutaneous flap harvested from the adjacent area of the wound. We believe it is an underused technique for advanced wound closure in the lower extremity. It offers several advantages compared with traditional, more difficult to perform, flaps. We have seen an excellent result 18 months after using the turnover flap in a patient with recurrent posterior heel ulceration with calcaneal osteomyelitis. PMID:23910737

    [Purpose] This study researched the effects of different types of high heels on the muscles surrounding the cervical spine, the thoracic spine, and the lumbar spine by analyzing muscle activation of the paraspinal muscles during standing while wearing high heels. The high heels were all of the same height: 8 cm. [Subjects and Methods] The 28 subjects in this experiment were females in their 20s with a foot size of 225–230 mm and a normal gait pattern. To measure the muscle activation of the paraspinal muscles, EMG electrodes were attached on the paraspinal muscles around C6, T7, and L5. The muscle activation during standing while wearing 8-cm-high wedge heels, setback heels, and French heels was then measured. The measurements were performed 3 times each, and the mean value was used for analysis. [Results] The levels of muscle activation of the paraspinal muscles induced by standing on wedge heels, setback heels, and French heels in the cervical and lumbar areas were significantly higher than those induced by standing on bare feet. But there was no significant difference according to the heel types. [Conclusion] The height of the heels presented a greater variable than the width of the heels on the muscle activation of paraspinal muscles. Therefore, wearing high heels is not recommended for those who have pain or functional problems in the cervical and/or lumbar spine. PMID:25642040

    Two cats that developed bilateral calcaneal stress fractures are reported. One cat developed lameness associated with incomplete fractures at the base of both calcanei, both of which progressed to acute, complete fractures 2 months later. The second cat presented with acute complete calcaneal fracture, with evidence of remodelling of the contralateral calcaneus, which subsequently fractured two years later. The calcaneal fractures were successfully stabilised with lateral bone plates in each case. Stress fractures were suspected because of the bilateral nature, the simple and similar configuration, the consistent location of the fractures, the absence of other signs of trauma in both cases and the suspected insidious onset of the lameness. The feline calcaneus is susceptible to stress fracture, and cats presenting with calcaneal fractures without evidence of trauma should be evaluated for concurrent skeletal pathology. PMID:25929309

    As the largest tarsal bone and the most inferior bone in the body, the calcaneus is responsible for supporting the axial load from the weight of the body. It is most commonly fractured after a fall from a height in which axial loads exceed its support capacity. Calcaneal fractures account for 60% of all tarsal fractures. Conventional radiography is commonly used for initial evaluation of calcaneal injury but has the typical disadvantages of two-dimensional imaging. Modern assessment of calcaneal fractures relies heavily on multidetector computed tomography (CT), which allows better visualization and characterization of fracture lines and fragment displacement. Calcaneal fractures observed at CT have been divided into intra- and extraarticular fractures on the basis of subtalar joint involvement. The Sanders classification system for intraarticular fractures is the most commonly used system because it correlates with clinical outcomes and involves less interobserver variability. The classification of extraarticular fractures has been less controversial and makes use of anatomic landmarks on the calcaneus to divide the bone into anterior, middle, and posterior areas. Soft-tissue involvement is an important aspect of calcaneal fracture assessment because it has been linked with poor functional outcomes. Familiarity with the normal anatomy of the calcaneus, the classification of calcaneal fractures, and the various complications of these fractures is essential for treatment assessment, especially if surgical intervention is required.

  9. An evaluation of a silicone adhesive shaped heel dressing.

    PubMed

    Hampton, Sylvie

    Tissue breakdown is complex and involves many factors. Pressure ulcer development in the heels is subject to extrinsic factors such as pressure, shear, friction and moisture. The heels are the most common sites for friction and shear damage, which can lead to blistering, skin erosion and tissue breakdown (Grey et al, 2006). To address the issues of wounds that are painful on dressing removal and friable skin, Smith & Nephew has introduced a soft silicone adhesive dressing to its Allevyn dressing range. Silicone does not adhere to wounded areas and can be removed gently without trauma to the periwound area. This paper discusses the findings of a 20-patient multi-site evaluation examining the performance and acceptability of Allevyn Gentle Border Heel dressing in the management of heel wounds.

    Background Calcaneal quantitative ultrasound (QUS), which is used in the evaluation of osteoporosis, is believed to be intimately associated with the characteristics of the proximal femur. However, the specific associations of calcaneal QUS with characteristics of the hip sub-regions remain unclear. Design A cross-sectional assessment of 53 osteoporotic patients was performed for the skeletal status of the heel and hip. Methods We prospectively enrolled 53 female osteoporotic patients with femoral fractures. Calcaneal QUS, dual energy X-ray absorptiometry (DXA), and hip structural analysis (HSA) were performed for each patient. Femoral heads were obtained during the surgery, and principal compressive trabeculae (PCT) were extracted by a three-dimensional printing technique-assisted method. Pearson’s correlation between QUS measurement with DXA, HSA-derived parameters and Young’s modulus were calculated in order to evaluate the specific association of QUS with the parameters for the hip sub-regions, including the femoral neck, trochanteric and Ward’s areas, and the femoral shaft, respectively. Results Significant correlations were found between estimated BMD (Est.BMD) and BMD of different sub-regions of proximal femur. However, the correlation coefficient of trochanteric area (r = 0.356, p = 0.009) was higher than that of the neck area (r = 0.297, p = 0.031) and total proximal femur (r = 0.291, p = 0.034). Furthermore, the quantitative ultrasound index (QUI) was significantly correlated with the HSA-derived parameters of the trochanteric area (r value: 0.315–0.356, all p<0.05) as well as with the Young’s modulus of PCT from the femoral head (r = 0.589, p<0.001). Conclusion The calcaneal bone had an intimate association with the trochanteric cancellous bone. To a certain extent, the parameters of the calcaneal QUS can reflect the characteristics of the trochanteric area of the proximal hip, although not specifically reflective of those of the femoral neck or shaft.

    Advancements in surgical technique have resulted in the ability to reconstruct lower extremity injuries that would have previously been treated by amputation. Currently, a paucity of data is available specifically addressing limb amputation versus reconstruction for calcaneal fractures with severe soft tissue compromise. Reconstruction leaves the patient with their native limb; however, multiple surgeries, infections, chronic pain, and a poor functional outcome are very real possibilities. We present the case of a complex calcaneal fracture complicated by soft tissue injury and osteomyelitis that highlights the importance of shared decision-making between patient and surgeon when considering reconstruction versus amputation. This case exemplifies the need for open communication concerning the risks and benefits of treatment modalities while simultaneously considering the patient's expectations and desired outcomes.

    [Purpose] This study aimed to analyze the effect of heel pads in ankle-foot orthoses on dynamic motion aspects of gait in stroke patients from the viewpoint of energy conversion efficiency. [Subjects] Fourteen chronic stroke patients who were ambulatory and had lower extremity motor function categorized as Brunnstrom stage IV participated in the study. [Methods] A three-dimensional motion analysis system was used to assess the effect of heel pad intervention on dynamic motion gait parameters using a single-system A-B-A design. [Results] The results showed that a heel pad attached to the ankle-foot orthosis caused significant retention of the center-of-pressure at the heel during the heel rocker function and significant increase in the dorsiflexion moment and the height of the center of gravity. [Conclusion] The present study showed that a heel pad attached to the calcaneal region of an ankle-foot orthosis caused slight retention of the center-of-pressure at the heel during the heel rocker function along with center of gravity elevation in the stance phase and improved the energy conversion efficiency, especially on the non-paretic side.

    2015-01-01

    Many heel pathologies including plantar heel pain may result from micro tears/trauma in the subcutaneous tissues, in which internal tissue deformation/stresses within the heel pad play an important role. Previously, many finite element models have been proposed to evaluate stresses inside the heel pad, but the majority of these models only focus on static loading boundary conditions. This study explored a dynamics modelling approach to the heel pad subjected to realistic impact loads during running. In this model, the inertial property and action of the body are described by a lumped parameter model, while the heel/shoe interactions are modelled using a viscoelastic heel pad model with contact properties. The impact force pattern, dynamic heel pad deformation and stress states predicted by the model were compared with published experimental data. Further parametrical studies revealed the model responses, in terms of internal stresses in the skin and fatty tissue, change nonlinearly when body dynamics changes. A reduction in foot's touchdown velocity resulted in a less severe impact landing and stress relief inside the heel pad, for example peak von-Mises stress in fatty tissue, was reduced by 11.3%. Applications of the model may be extendable to perform iterative analyses to further understand the complex relationships between body dynamics and stress distributions in the soft tissue of heel pad during running. This may open new opportunities to study the mechanical aetiology of plantar heel pain in runners. PMID:24980181

    This paper describes the observation of rearward movement (RM) of the heel following heel strike occurring during normal gait. Thirty-one participants recruited as part of a larger study on slip kinematics walked the length of an 8-m runway at a speed of 1.5 m/s. Several floor surfaces, presented dry and with contaminant, were used for the purpose of eliciting a wide range of small slip distances. The normal force applied to a forceplate mounted in the runway was used to identify heel strike, as well as to calculate the utilized coefficient of friction during early stance phase. A motion analysis system tracked the displacement of two heel-mounted markers, and the data were used to derive kinematic variables related to the heel strike event. Results showed that RMs occurred in 18.1% of 494 trials, with a mean rearward displacement of 5.02 (+/-3.68) mm. When present, RMs occurred in close temporal proximity to heel strike, typically completing RM within 40 ms of the heel strike event. When divided into groups by age, older participants (>40 years) were more than twice as likely to have RMs as younger participants. When grouped by height or weight, differences in the proportion of trials with RMs were small. In trials where RMs were observed, forward slip distances were significantly less than for trials with no RMs, 2.17 (+/-3.87) mm vs. 12.58 (+/-10.71) mm, respectively. The time until the heel stopped moving during the post-heel strike period was not significantly different between RM and non-RM trials. Further investigation of this gait feature may improve understanding of normal gait patterns and may have implications for future slipmeter development. PMID:18280459

    Calcaneal fractures are injuries that occur generally as the result of high-energy mechanisms, and, as such, the presence of concurrent injuries should be suspected. The presence of peroneal tendon and superior retinacular injuries has been underreported. We sought to report the incidence of peroneal tendon pathologic features in our population of patients with calcaneal fractures, with emphasis on the method of identification. Furthermore, we sought to identify whether specific fracture patterns were more commonly associated with this pathologic finding. Of the 97 cases, 13 (13.4%) required repair of the superior peroneal retinaculum, 11 of which demonstrated the Sanders A fracture line. Our findings have demonstrated an incidence of pathologic features, in particular, with the presence of the Sanders A fracture line, that warrants attention to potentially help improve the outcome of these devastating injuries.

    PURPOSE: This study of the foot uses experimentally measured kinematic and kinetic data with a numerical model to evaluate in vivo calcaneal stresses during walking and running. METHODS: External ground reaction forces (GRF) and kinematic data were measured during walking and running using cineradiography and force plate measurements. A contact-coupled finite element model of the foot was developed to assess the forces acting on the calcaneus during gait. RESULTS: We found that the calculated force-time profiles of the joint contact, ligament, and Achilles tendon forces varied with the time-history curve of the moment about the ankle joint. The model predicted peak talocalcaneal and calcaneocuboid joint loads of 5.4 and 4.2 body weights (BW) during walking and 11.1 and 7.9 BW during running. The maximum predicted Achilles tendon forces were 3.9 and 7.7 BW for walking and running. CONCLUSIONS: Large magnitude forces and calcaneal stresses are generated late in the stance phase, with maximum loads occurring at approximately 70% of the stance phase during walking and at approximately 60% of the stance phase during running, for the gait velocities analyzed. The trajectories of the principal stresses, during both walking and running, corresponded to each other and qualitatively to the calcaneal trabecular architecture.

    Intraarticular calcaneal fracture treatments that result in malalignment often require reconstructive surgery. Seven cases are used to demonstrate the intricacies of reconstructive case management. Reestablishment of calcaneal height, length, orientation, and position relative to the other tarsals is necessary to reestablish appropriate foot function. Inherent or acquired gastrocnemius equinus should be treated with recession to reduce destructive forces on the reconstruction. PMID:26915782

    Computed tomography (CT) of 25 fractured calcanei was performed to investigate the potential of CT in evaluating the pattern and biomechanics of these fractures. The characteristic findings of typical fractures are presented, including the number and type of principal fragments, size and dislocation of the sustentacular fragment, and involvement of the anterior and posterior facets of the subtalar joint. In 17 cases, the calcaneus consisted of four or more fragments. Furthermore, in 17 cases the sustentacular fragment included all or part of the posterior facet joint. In 18 of the 25 cases, the sustentacular fragment was displaced. It is concluded that well performed CT is an invaluable adjunct in understanding the fracture mechanism and in detecting pain-provoking impingement between the fibular malleolus and the tuberosity fragment.

    Article whose content was exposed in the workshops of the GNEAUPP Congress, held in Seville in November2012, and which refers to ulcers by pressure on the heels as a location exposed to the analysis. A pressure ulcer is a lesion located in skin I underlying tissue usually over a bone prominence, as a result of the pressure, or pressure in combination with the shears. A number of contributing factors or confounding factors are also associated with ulcers by pressure; the importance of these factors still not been elucidated. The heels are next to the sacred area, parts of the body that most frequently presents ulcers by pressure, The importance of the predisposing factors for ulcers in the sacral area as humidity has been studied in recent years, but in heels, remains one of the most important locations in the extremities, which entails adverse outcomes such as amputation in persons with comorbid diseases like Diabetes Mellitus (DM). The incidence of ulcers on heels in patients with DM and without it, is approximately 19-32%. Everything and be a problem associated with elderly people and chronic pathologies, in acute patients are a problem that this underrated, but not devoid of controversy. In hospitals of treble in 2006, the NPUAP encrypted the incidence of UPPin heels in a 43%; in one systematic review conducted by Reddy et al. (2006) puts revealed that 60% of pressure ulcers is produced. The problem of the UPP in heels is present in all the areas of intervention and particularly in paediatric units intensive care, where the first localization it is the occipital area followed by the heels.

    The calcaneus is the most frequently fractured tarsal bone. Compartment syndrome (CS) complicates fractures and other injuries and is most commonly described in association with the lower leg. The long-term sequelae of CS of the foot can include toe clawing, permanent loss of function, persistent pain, muscle atrophy, contracture, painful warts, weakness, and sensory disturbances. The incidence and clinical significance of untreated CS after calcaneal fractures were questioned. All compliant patients treated by us for a calcaneus fracture underwent a physical examination and medical interview: 47 (49 fractures) were included in the final cohort (36 males, 11 females, mean age 49 ± 14.5 years, mean follow-up 23 ± 16 months). Missed CS sequelae were diagnosed by the presence of claw toes and plantar sensory deficits. The functional outcome and pain at rest and during activity were scored. Five patients (10%) had missed CS, and their functional score was significantly lower than for those without CS (52 ± 21.5 versus 77.4 ± 22 for no CS, p < .05). All missed CS cases were diagnosed in patients with a Sanders type 3 or 4 fracture. Intra-articular fracture was a significant factor associated with developing CS sequelae (p = .045). Untreated CS can cause muscle and nerve injury and contribute to a poor functional outcome. Because CS is more likely to develop after highly comminuted intra-articular fractures, these patients warrant close monitoring for CS development. Early detection and treatment might result in fewer late disabling sequelae of this injury. PMID:23321291

    The objective was to report on a rare case of chondrosarcoma of the bones of the foot, and specifically the calcaneus. The patient was a 30-year-old woman with a complaint of painless nodulation on the lateral face of the calcaneus, which she had had for around eight years, which then started to present significant pain. Radiography showed a tumor with imprecise limits, compromising the calcaneus, talus and lateral malleolus. The lesion had a destructive, aggressive and osteolytic appearance, with invasion of the surrounding soft tissues and the presence of points of calcification. Amputation was performed in the middle third of the right lower leg, with a histological diagnosis of chondrosarcoma. The case evolved with local recurrence of the tumor formation and subsequent amputation in the middle third of the right thigh. One year after the second amputation, the patient evolved with metastasis from the chondrosarcoma in soft tissues throughout the body and in the lungs, and she died one year and ten months after the diagnosis was made. Chondrosarcomas that involve the calcaneus are rare in young adults, with few reports in the literature. For this reason, the present report becomes important in that it shows that even though this is a rare condition, it is present in our environment. Early investigation is essential, especially by means of imaging examinations, with the aim of diminishing the chances of malignant transformation and consequent complications, so as to avoid death.

    Research has found that the appearance of women's apparel helps increase their attractiveness as rated by men and that men care more about physical features in potential opposite-sex mates. However, the effect of sartorial appearance has received little interest from scientists. In a series of studies, the length of women's shoe heels was examined. A woman confederate wearing black shoes with 0, 5, or 9 cm heels asked men for help in various circumstances. In Study 1, she asked men to respond to a short survey on gender equality. In Study 2, the confederate asked men and women to participate in a survey on local food habit consumption. In Study 3, men and women in the street were observed while walking in back of the female confederate who dropped a glove apparently unaware of her loss. It was found that men's helping behavior increased as soon as heel length increased. However, heel length had no effect on women's helping behavior. It was also found that men spontaneously approached women more quickly when they wore high-heeled shoes (Study 4). Change in gait, foot-size judgment, and misattribution of sexiness and sexual intent were used as possible explanations. PMID:25408499

    Plantar fasciitis is a common injury to the plantar aponeurosis, manifesting as pain surrounding its proximal insertion at the medial calcaneal tubercle. Pain is typically worse in the morning when getting out of bed, and may subside after the tissue is sufficiently warmed up. For running-based athletes and individuals who spend prolonged periods of time on their feet at work, plantar fasciitis may become recalcitrant to conservative treatments such as ice, rest, and anti-inflammatory medication. Exercise-based therapies have received only limited attention in the literature for this common problem, yet they are becoming increasingly validated for pain relief and positive tissue remodeling at other sites of similar soft-tissue overuse injury. This study reports on pain outcomes in individuals experiencing chronic plantar fasciitis while wearing a shoe with an ultraflexible midsole (Nike Free 5.0) (FREE) versus a conventional training (CON) shoe in a 12-week multielement exercise regimen, and after a 6-month follow-up. Adults with >or= 6-month history of painful heel pain were recruited and randomly assigned to wear 1 of the 2 shoes. All subjects completed the same exercise protocol. A visual analogue scale item tracked peak pain in the preceding 24 hours taken at baseline, 6- and 12-week points, and at the 6-month follow-up. Twenty-one subjects completed the program (9 FREE; 12 CON). Both groups reported significant improvements in pain by the 6-month follow-up, and the FREE group reported an overall reduced level of pain throughout the study as a result of lower mean pain scores at the midpoint and post-test compared with the CON group. The exercise regimen employed in this study appears to reduce pain associated with chronic plantar fasciitis, and in doing so, the Nike 5.0 shoe may result in reductions in pain earlier than conventional running shoes.

    Heel pain is a frequent disabling symptom. Clinical diagnosis is often difficult with a large range of possible diagnoses. Lesions of the plantar fascia form an important group. We present a review describing the common lesions of the plantar fascia, including plantar fasciitis, plantar fascia rupture, plantar fibromatosis, and plantar xanthoma, and illustrate them with appropriate magnetic resonance imaging (MRI) and ultrasound imaging. We also address foreign-body reactions, enthesopathy, and diabetic fascial disease. PMID:19664484

    [Purpose] The purpose of this study was to investigate the effects of different height of high heels on muscle activation of the paraspinalis cervicis and erector spinae in healthy young women. [Subjects and Methods] Thirteen healthy women were recruited in this study. To examine the effects of different heights of heels on muscle activation, the paraspinalis cervicis (cervical spine) and erector spinae (lumbar spine) were measured at the time of heel strike and toe off during gait on three different conditions (barefoot, 4 cm high heels, and 10 cm high heels). There are no previous trials or reports that have evaluated this approach in patients with chronic neck pain. [Results] A significant increase in muscle activation of the paraspinalis cervicis and erector spinae at heel strike and toe off (except that of the paraspinalis cervicis at toe off in healthy subjects) was observed in the under 10 cm high heel condition as, compared to that with barefoot condition, in all the subjects. [Conclusion] The height of the high heels affects to the activation demand of the paraspinalis cervicis and erector spinae in patients with neck pain. PMID:27134392

    Objective: To examine the effects of oral sucrose on procedural pain, and on biochemical markers of adenosine triphosphate utilization and oxidative stress in preterm neonates with mild to moderate respiratory distress. Study design: Preterm neonates with a clinically required heel lance that met study criteria (n = 49) were randomized into three groups: (1) control (n = 24), (2) heel lance treated with placebo and non-nutritive sucking (n = 15) and (3) heel lance treated with sucrose and non-nutritive sucking (n = 10). Plasma markers of adenosine triphosphate degradation (hypoxanthine, xanthine and uric acid) and oxidative stress (allantoin) were measured before and after the heel lance. Pain was measured using the Premature Infant Pain Profile. Data were analyzed using repeated measures analysis of variance, chi-square and one-way analysis of variance. Results: We found that in preterm neonates who were intubated and/or were receiving ⩾30% FiO2, a single dose of oral sucrose given before a heel lance significantly increased markers of adenosine triphosphate use. Conclusion: We found that oral sucrose enhanced adenosine triphosphate use in neonates who were intubated and/or were receiving ⩾30% FiO2. Although oral sucrose decreased pain scores, our data suggest that it also increased energy use as evidenced by increased plasma markers of adenosine triphosphate utilization. These effects of sucrose, specifically the fructose component, on adenosine triphosphate metabolism warrant further investigation. PMID:26770807

    Forefoot pain is common in high-heeled shoe wearers due to the high pressure caused by the center of body mass moving forward and the increased arch height with heel elevation. Sufficient arch support could reduce the high pressure over forefoot. However, too much arch support could lead to abnormal foot alignment and pain over midfoot. Little information is reported on the relationship among plantar arch height, shank curve design and plantar pressure. This study aimed at quantifying the plantar arch height changes at different heel heights and investigating the effect of shank curve on plantar pressure distribution. The plantar arch height increased to (7.6±1.3)mm at heel height of 75 mm. The Chinese standard suggests the depth of last should be 8.5mm for heel height of 75 mm. When a shank curve with higher depth of last (11 mm) was used, the peak pressure over forefoot further decreased in midstance phase, which might ease the forefoot problems, while the peak pressure over midfoot increased but not exceeded the discomfort pressure thresholds. To achieve a more ideal pressure distribution in high-heeled shoes, a higher than expected depth of last would be suggested that would not cause discomfort over midfoot.

    The purpose of the present study was to compare the clinical and radiographic results between 2 procedures, lateral opening wedge calcaneal osteotomy (LCL) and medial calcaneal sliding-opening wedge cuboid-closing wedge cuneiform osteotomy (3C) in patients with planovalgus foot deformity. A total of 38 patients who underwent either LCL (18 patients, 28 feet) or 3C (20 patients, 32 feet) were included in the present study. The etiology of the planovalgus foot deformity was idiopathic in 16 feet and cerebral palsy in 44 feet. The 2 procedures used in the present study were indicated in symptomatic (pain or callus) children in whom conservative treatment, such as shoe modifications or orthotics, had been applied for more than 1 year but had failed. The patients were evaluated preoperatively, postoperatively, and at the last follow-up visit, both clinically and radiologically, and the interval to union and postoperative courses were compared between the 2 groups. In the LCL group, 19 of the 28 feet (68%) showed a satisfactory outcome and 9 (32%) an unsatisfactory outcome. In the 3C group, 28 of the 32 feet (88%) showed a satisfactory outcome and 4 (12%) an unsatisfactory outcome. The clinical results were not significantly different between the 2 groups, with mild to moderate pes planovalgus deformity. However, the clinical results were better in the 3C group with severe pes planovalgus deformity than in the LCL group with severe pes planovalgus deformity. All 4 radiographic parameters were improved at the last follow-up visit in both groups. In particular, the talar-first metatarsal angle and the calcaneal pitch angle on the weightbearing lateral radiographs were significantly improved in the 3C group with mild to moderate planovalgus foot deformity. All 4 parameters were significantly improved in the 3C group with severe planovalgus foot deformity. No significant differences were observed between the 2 groups in terms of the interval to union and postoperative care. No case of postoperative deep infection or nonunion was encountered in either group. 3C is a more effective procedure than LCL for the correction of pes planovalgus deformity in children, especially severe pes planovalgus deformities.

    Heels are at increased risk of injury due to the posterior prominence and lack of padding over the calcaneus. Pressure injuries, once established, are extremely costly, both in terms of the detrimental effect on psychosocial wellbeing and threat to life, as well as financially due to length of hospital stay and resources used to heal the wounds. A new and inexpensive silicone heel pad has been designed to simplify the necessary decisions and to address the problems associated with pressure injuries to the heels. This article will describe an observational evaluation of the product. KerraPro Heel pads were evaluated in two separate cohorts of 17 participants over a 4-week period with the primary aim to evaluate the efficacy of the product in preventing and alleviating pressure injuries on the heels. All participants had been reported as 'at risk' or 'at high risk' of pressure injury to the heels and had a history of developing such lesions. The KerraPro heel pads were compared with the participant's standard protocol. The outcome of the evaluation demonstrated the effectiveness of the KerraPro Heel pads in the prevention and treatment of heel pressure injuries. PMID:24225600

    Invasive stimulation of the motor (precentral) cortex using surgically implanted epidural electrodes is indicated for the treatment of neuropathic pain that is refractory to medical treatment. Controlled trials have demonstrated the efficacy of epidural motor cortex stimulation (MCS), but MCS outcome remains variable and validated criteria for selecting good candidates for implantation are lacking. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive approach that could be used as a preoperative tool to predict MCS outcome and also could serve as a therapeutic procedure in itself to treat pain disorders. This requires repeated rTMS sessions and a maintenance protocol. Other studies have also demonstrated the efficacy of transcranial direct current stimulation (tDCS) in relieving chronic pain syndromes. The most studied target is the precentral cortex, but other targets, such as the prefrontal and parietal cortices, could be of interest. The analgesic effects of cortical stimulation relate to the activation of various circuits modulating neural activities in remote structures, such as the thalamus, limbic cortex, insula, or descending inhibitory controls. In addition to the treatment of refractory neuropathic pain by epidural MCS, new developments of this type of strategy are ongoing, for other types of pain syndrome and stimulation techniques.

    Background To compare the effectiveness of intraoperative three-dimensional (3D) image and conventional two-dimensional (2D) fluoroscopic images, which are used in the treatment of acute calcaneal fractures. Methods We retrospectively analyzed 40 patients who suffered calcaneal fracture and underwent surgery at Inje University Busan Paik Hospital. The patients were divided into two groups. Only 2D fluoroscopy was used to evaluate 20 patients of group 1. On the other hand, 3D fluoroscopy was performed on the remaining 20 patients of group 2; 3D fluoroscopy was performed on these patients after they were extensively evaluated by 2D fluoroscopy during surgery. We reviewed the radiographic and clinical outcomes of these patients, whose average follow-up period was 42.6 months. Results In group 2, 3D fluoroscopy detected four cases (20%) of articular incongruence and screw misplacement. All these complicated cases were corrected during surgery. At the final follow-up session, the mean American Orthopedic Foot and Ankle Society (AOFAS) hind foot score was 78.3 (range, 65 to 95) in group 1 and 82.3 (range, 68 to 95) in group 2. Conclusions Intraoperative 3D imaging of calcaneal fractures is considered to be useful in evaluating the congruence of joints and the placement of implants. PMID:26640632

    Talo-calcaneal coalitions may be intra-articular or extra-articular in position and may be classified as fibrous, cartilaginous or osseous in morphology. Fibrous coalitions, particularly extra-articular talo-calcaneal coalitions, may have cross-sectional imaging findings that resemble normal anatomic variants, particularly the medial talo-calcaneal ligament and to a lesser extent the presence of an accessory articular facet between the posterior margin of the sustentaculum and postero-medial process of the talus. Typically, in the adult fibrous coalition, there will be some osseous deformity at the entheses, allowing differentiation from a medial talo-calcaneal ligament. The anatomy of the subtalar joint and its ligamentous supports, normal anatomic variations and their corresponding imaging appearance are reviewed in the first part of this article. In the second part, the various forms of talo-calcaneal coalition and their imaging appearance are reviewed. PMID:19096839

    Objectives To conduct the first systematic review from an epidemiological perspective regarding the association between high-heeled shoe wear and hallux valgus, musculoskeletal pain, osteoarthritis (OA) and both first-party and second-party injury in human participants without prior musculoskeletal conditions. Setting A systematic review of international peer-reviewed scientific literature across seven major languages. Data sources Searches were conducted on seven major bibliographic databases in July 2015 to initially identify all scholarly articles on high-heeled shoes. Supplementary manual searches were conducted. Titles, abstracts and full-text articles were sequentially screened to identify all articles assessing epidemiological evidence regarding the association between high-heeled shoe wear and hallux valgus, musculoskeletal pain, OA and both first-party and second-party injury in human participants without prior musculoskeletal conditions. Standardised data extraction and quality assessment (Threats to Validity tool) were conducted. Primary and secondary outcome measures Musculoskeletal pain or OA as assessed by clinical diagnosis or clinical assessment tool. First-party or second-party injury. Results 644 unique records were identified, 56 full-text articles were screened and 18 studies included in the review. Four studies assessed the relationship with hallux valgus and three found a significant association. Two studies assessed the association with OA and neither found a significant association. Five studies assessed the association with musculoskeletal pain and three found a significant association. Eight studies assessed first-party injury and seven found evidence of a significant injury toll associated with high-heeled shoes. One study provided data on second-party injury and the injury toll was low. Conclusions High-heeled shoes were shown to be associated with hallux valgus, musculoskeletal pain and first-party injury. No conclusive evidence regarding OA and second-party injury was found. Societal and clinical relevance of these findings is discussed. Concern is expressed about the expectation to wear high-heeled shoes in some work and social situations and access by children. PMID:26769789

    Specialized acrobatic leaping has been recognized as a key adaptive trait tied to the origin and subsequent radiation of euprimates based on its observed frequency in extant primates and inferred frequency in extinct early euprimates. Hypothesized skeletal correlates include elongated tarsal elements, which would be expected to aid leaping by allowing for increased rates and durations of propulsive acceleration at takeoff. Alternatively, authors of a recent study argued that pronounced distal calcaneal elongation of euprimates (compared to other mammalian taxa) was related primarily to specialized pedal grasping. Testing for correlations between calcaneal elongation and leaping versus grasping is complicated by body size differences and associated allometric affects. We re-assess allometric constraints on, and the functional significance of, calcaneal elongation using phylogenetic comparative methods, and present an evolutionary hypothesis for the evolution of calcaneal elongation in primates using a Bayesian approach to ancestral state reconstruction (ASR). Results show that among all primates, logged ratios of distal calcaneal length to total calcaneal length are inversely correlated with logged body mass proxies derived from the area of the calcaneal facet for the cuboid. Results from phylogenetic ANOVA on residuals from this allometric line suggest that deviations are explained by degree of leaping specialization in prosimians, but not anthropoids. Results from ASR suggest that non-allometric increases in calcaneal elongation began in the primate stem lineage and continued independently in haplorhines and strepsirrhines. Anthropoid and lorisid lineages show stasis and decreasing elongation, respectively. Initial increases in calcaneal elongation in primate evolution may be related to either development of hallucal-grasping or a combination of grasping and more specialized leaping behaviors. As has been previously suggested, subsequent increases in calcaneal elongation are likely adaptations for more effective acrobatic leaping, highlighting the importance of this behavior in early euprimate evolution.

    High heels are a major source of chronic lower limb pain. Yet, more than one third of all women compromise health for looks and wear high heels on a daily basis. Changing from flat footwear to high heels induces chronic muscle shortening associated with discomfort, fatigue, reduced shock absorption, and increased injury risk. However, the long-term effects of high-heeled footwear on the musculoskeletal kinematics of the lower extremities remain poorly understood. Here we create a multiscale computational model for chronic muscle adaptation to characterize the acute and chronic effects of global muscle shortening on local sarcomere lengths. We perform a case study of a healthy female subject and show that raising the heel by 13 cm shortens the gastrocnemius muscle by 5% while the Achilles tendon remains virtually unaffected. Our computational simulation indicates that muscle shortening displays significant regional variations with extreme values of 22% in the central gastrocnemius. Our model suggests that the muscle gradually adjusts to its new functional length by a chronic loss of sarcomeres in series. Sarcomere loss varies significantly across the muscle with an average loss of 9%, virtually no loss at the proximal and distal ends, and a maximum loss of 39% in the central region. These changes reposition the remaining sarcomeres back into their optimal operating regime. Computational modeling of chronic muscle shortening provides a valuable tool to shape our understanding of the underlying mechanisms of muscle adaptation. Our study could open new avenues in orthopedic surgery and enhance treatment for patients with muscle contracture caused by other conditions than high heel wear such as paralysis, muscular atrophy, and muscular dystrophy.

    The most effective way to treat calcaneal malunions is avoidance. With any articular fracture, progressive arthrosis and dysfunction are common. By restoring the anatomy initially through reduction, late reconstructive options become less complicated. Numerous studies have shown that restoration of the anatomic alignment either through percutaneous or open techniques is effective. In patients with no or minimal articular degeneration, extrarticular joint-sparing procedures can be performed. This represents a small select group who may benefit from simple osteotomy procedures with associated soft tissue reconstruction, if needed. PMID:26915784

    As part of the tank calibration process, the instrument heel is that part of the tank that cannot be measured by the liquid level instrumentation. if the tank being calibrated is not a bottom drain tank, some volume of fluid will be present in the bottom of the tank after draining as much as possible. The amount of fluid remaining in the tank at the start of each run can be estimated by measuring a concentration change of an added spiking material. With the great improvement of liquid level measuring instruments, the total error associated with the instrument heel determination can be greatly affected by the laboratory method used to measure the concentration difference. At the Savannah River Site, the laboratory method used has historically been Direct Current Plasma Emission Spectroscopy, which yielded very marginal results at best. In the most recent tank calibrations, the laboratory method was changed to Absorption Spectrophotometry, which reduces the total error on the instrument heel measurement by a factor of 2.5 times. This paper describes the method used to determine tank instrument heels and the improvements made to this process.

    Calcaneal osteomyelitis presents a complicated situation. The specific anatomy of the os calcis and its surrounding soft tissues plays an important role in the planning and realization of the procedures needed in order to eradicate the osteomyelitic focus. The calcaneus represents a spongious bone; a fact that supports the developement of an osteomyelitis. It is the strongest bone of the foot and is highly important for the biomechanical features of physiological walking. The surrounding soft tissues are thin and contain various important anatomical structures. These might be damaged during the treatment of the osteomyelitis. In addition the vascularization of the os calcis is delicate and may be compromized during the surgical osteomyelitis treatment. Calcaneus osteomyelitis may be classified based on the routes of infection into exogenous and endogenous forms. Additionally from the clinical point of view acute and chronic forms may be distinguished from an early and a late infection. Exogenous calcaneal osteomyelitis mostly is the result of an infection with S. aureus. The treatment is equal to the therapy in other locations and based on: Eradication of the bone infection Sanitation of the soft tissue infection Reconstruction of bone and soft tissue Especially the preservation and restoration of the soft tissue is important. Thus plastic surgical procedures play an essential role. The main object of treatment is the preservation of a biomechanical functioning foot. This may be impossible due to the local situation. Calcanectomy or even below knee amputation may be needed in those cases. PMID:26504695

    Objective : To assess intra- and interobserver reproducibility of Sanders Classification System of calcaneal fractures among experienced and less experienced observers. Methods : Forty-six CT scans of intra-articular calcaneal fractures were reviewed. Four observers, two with ten years of experience in foot and ankle surgery and two third-year residents in Orthopedics and Traumatology classified the fractures on two separate occasions three weeks apart from each other. The intra and inter-observer reliability was analyzed using the Kappa index. Results : There was good intraobserver reliability for the two experienced observers and one less experienced observer (Kappa values 0.640, 0.632 and 0.629, respectively). The interobserver reliability was fair between the experienced observers (Kappa = 0.289) and moderate among the less experienced observers (Kappa = 0.527). Conclusions : The Sanders Classification System showed good intraobserver reliability, but interobserver reproducibility below the ideal level, both among experienced and less experienced observers.

    Objective: Verify the variables of plantar pressure distribution of patients submitted to surgical procedure for calcaneal fracture, and correlate them with two different surgical approaches. Method: The authors studied 15 patients between 20 and 53 years of age (average 40.06 yrs.) who had intra-joint calcaneal fractures, submitted to surgical treatment by means of two different approaches: the lateral and the sinus tarsi. The authors checked the plantar pressure distribution by correlating these variables with the two different surgical approaches. The plantar pressure distribution was assessed using the Pedar System (Novel, Gmbh, Munich, Germany), by checking the maximum peak of the hindfoot and forefoot pressure on the affected and the normal sides. Results: the mean maximum pressure of the hindfoot plantigram in both approaches showed no statistical difference (t=0.11; p=0.91), as well as the mean maximum pressure of the forefoot plantigram (t=-0,48; p=0,64). Conclusion: The authors have concluded that there were no significant statistical differences between the average maximum peak of the hindfoot and forefoot pressure on the affected side as compared to the normal side, and these variables have showed no differences when compared to the surgical approach used.

    Calcaneal fractures are one of the most difficult fractures to surgically manage and often require a steep learning curve to achieve consistent results. They usually occur in young individuals with labor intensive occupations and are associated with major complications. Conservative treatment of intraarticular calcaneal fractures with displacement often results in significant deformity, bone loss, and posttraumatic arthrosis. Optimally, an open approach is required in most cases to achieve anatomic reduction and successful long-term outcomes. PMID:20691371

  10. Calcaneal robusticity in Plio-Pleistocene hominins: implications for locomotor diversity and phylogeny.

    PubMed

    Prang, Thomas C

    2015-03-01

    A key pedal adaptation to bipedality is a relatively large, weight-bearing calcaneus. The earliest evidence for a human-like, robust calcaneus is at 3.2 Ma in Australopithecus afarensis (A.L. 333-8, A.L. 333-55, A.L. 333-37) from Hadar, Ethiopia. Australopithecus sediba at 1.98 Ma from Malapa, South Africa displays a unique combination of primitive australopith features and more derived Homo-like features, but surprisingly is characterized by a gracile, chimpanzee-like calcaneus. The differences in calcaneal morphology suggest that these taxa differed in the frequency of arboreality and in the manner of foot function during terrestrial bipedal locomotion. This study examines calcaneal morphology in extant hominids (i.e., great apes and humans; N = 95) and fossil hominins (N = 5) to better understand the evolutionary development of calcaneal robusticity in early hominins. In particular, this study focuses on two additional fossil hominin calcanei that have not figured prominently in previous discussions of calcaneal robusticity: StW 352 and Omo 33-74-896. A measure of calcaneal robusticity was quantified as the ratio of calcaneal tuber cross-sectional area to calcaneal tuber length, which significantly differs between humans and non-humans using a sequential Bonferroni alpha adjustment for multiple comparisons. Additional multivariate analyses using Mosimann shape variables show that StW 352 and Omo 33-74-896 are more similar to Au. sediba in calcaneal tuber morphology than to Au. afarensis, suggesting that the latter taxon is better adapted for terrestrial bipedalism than at least some later species of Australopithecus. This finding implies the possibility of several complex evolutionary scenarios involving either multiple reversals in postcranial morphology in Australopithecus or the independent acquisition of adaptations to terrestrial bipedalism in Au. afarensis and Homo.

    To discuss and evaluate the method and effect of using calcaneal anatomic plate in treatment of intra-articular fractures of the calcaneus with assistant of arthroscope, 86 intra-articular fractures of the calcaneus in 78 patients were reduced by open reduction, and rigid fixation was made with calcaneal anatomic plate under assistant of arthroscope. The average follow-up duration was 18 months (range 12-30 months). The effect of treatment was evaluated according to AOFAS and X-ray before and after operation. The results showed that 86 patients have obtained satisfactory reduction according to X-ray, and there was significant difference before and after operation (P < 0. 01), the total excellent and fine rate was 91.86%. Treating intra-articular fractures of the calcaneus with calcaneal anatomic plate under arthroscope may provide more chance to achieve anatomical reconstruction, which can lead to satisfied recovery of function and few complication.

    Objective To evaluate the effect of custom molded foot orthoses on children with growing pains of the lower extremities. Methods Children with growing pains were recruited during a clinic visit. None had any bony deformities, inflammatory joint disease or depression. Resting calcaneal stance position (RCSP) and calcaneal pitch angle were measured, and individual custom molded rigid foot orthoses were prescribed using the inverted orthotic technique to control for foot overpronation using the RCSP angle. Pain sites, degree and frequency of pain, and balance ability were evaluated using Balance Master computerized posturography prior to foot orthosis fitting, and 1 and 3 months later. Results Twenty children completed the study. Seventeen (75%) had overpronated feet. Significant improvements were noted after 1 and 3 months in pain degree and frequency, and after 3 months in balancing ability. Conclusion The use of custom molded foot orthoses is a good method for treating children with multiple musculoskeletal pains in the leg. PMID:25932426

    At the Savannah River Site in Aiken, South Carolina, there are approximately 40 million gallons of legacy High Level Waste stored in large capacity sub-surface tanks. Twelve of these tanks are single-containment, non-conforming tanks with leaks. These tanks were built in the 1950s. Some of these tanks contain sludge heels and are being considered for near-term removal efforts and vitrification. Currently, only mechanical methods (i.e., pumps) are used to remove the sludge waste with varying degrees of success. To provide for additional levels of removal, chemically-aided techniques are being considered. The objective of the was to collect and evaluate information available on chemical-based methods for removing residual solids from the Site's waste tanks. As part of this study, the team was requested to develop recommendations for chemical treatments to remove residual heels (primarily sludge). Ideally, one agent alone would be efficient at dissolving all residual tank heels and yet satisfy all safety and process concerns. No such chemical cleaning agent was found. The cleaning agents identified from the literature, included oxalic acid, a mixture of oxalic acid and citric acid, a combination of oxalic acid with hydrogen peroxide, nitric acid, formic acid, and organics. A criteria matrix for evaluating the various cleaning agents was developed. The results of the evaluation conclusively support oxalic acid as the cleaning agent of choice for the immediate future. Oxalic acid scored nearly double the next closest cleaning agent. Nitric acid, formic acid, and oxalic acid with hydrogen peroxide were all closely grouped for the next best choice. The mixture of oxalic acid and citric acid rated poorly. Organics rated even more poorly due to large uncertainties in performance and downstream impacts.

    Wearing high heels (HH) places the calf muscle-tendon unit (MTU) in a shortened position. As muscles and tendons are highly malleable tissues, chronic use of HH might induce structural and functional changes in the calf MTU. To test this hypothesis, 11 women regularly wearing HH and a control group of 9 women were recruited. Gastrocnemius medialis (GM) fascicle length, pennation angle and physiological cross-sectional area (PCSA), the Achilles' tendon (AT) length, cross-sectional area (CSA) and mechanical properties, and the plantarflexion torque-angle and torque-velocity relationships were assessed in both groups. Shorter GM fascicle lengths were observed in the HH group (49.6+/-5.7 mm vs 56.0+/-7.7 mm), resulting in greater tendon-to-fascicle length ratios. Also, because of greater AT CSA, AT stiffness was higher in the HH group (136.2+/-26.5 N mm(-1) vs 111.3+/-20.2 N mm(-1)). However, no differences in the GM PCSA to AT CSA ratio, torque-angle and torque-velocity relationships were found. We conclude that long-term use of high-heeled shoes induces shortening of the GM muscle fascicles and increases AT stiffness, reducing the ankle's active range of motion. Functionally, these two phenomena seem to counteract each other since no significant differences in static or dynamic torques were observed. PMID:20639419

    Reconstruction of weight-bearing surfaces at the foot and ankle is controversial. Free tissue transfer and local fasciocutaneous perforator flaps are preferred for plantar reconstruction, but high rates of flap breakdown and ulceration have caused unsatisfactory functional outcomes. We present a modified "sural fasciomyocutaneous perforator flap" and its functional outcome. Between January 2007 and September 2010, 19 patients were treated for soft-tissue defects in the weight-bearing area with sural fasciomyocutaneous perforator flaps. The gastrocnemius, preserved in the base of the flap, was applied as padding under the calcaneus. In follow-up from 9 to 25 months (mean 13.8 months), each patient's pain score, defect size, ulcer formation, protective sensation recovery, and normal footwear were analyzed. The majority of the flaps survived with satisfactory aesthetic and functional results. One case of partial flap loss and one case of delayed ulceration were noted. With partial weight bearing at 4 weeks, satisfactory gait recovery was obtained at 5 to 8 months (in conjunction with protective sensation recovery). Sural fasciomyocutaneous perforator flap is a reliable modality in heel construction, showing advantages of low ulceration rate, durability, and good protective sensation recovery compared with conventional free tissue transfer and local fasciocutaneous perforator flap.

    In a joint effort, the Savannah River Laboratory (SRL), Savannah River Plant (SRP), and the Rocky Flats Plant (RFP) have developed two processes to recover plutonium from electrorefining anode heel residues. Aqueous dissolution of anode heel metal was demonstrated at SRL on a laboratory scale and on a larger pilot scale using either sulfamic acid or nitric acid-hydrazine-fluoride solutions. This direct anode heel metal dissolution requires the use of a geometrically favorable dissolver. The second process developed involves first diluting the plutonium in the anode heel residues by alloying with aluminum. The alloyed anode heel plutonium can then be dissolved using a nitric acid-fluoride-mercury(II) solution in large non-geometrically favorable equipment where nuclear safety is ensured by concentration control.

    Management of intra-articular calcaneal fractures during the past years has ranged from the nihilistic approach of no active treatment to open reduction and internal fixation or even to early subtalar arthrodesis. Operative treatment presents the surgeon with many challenges. Good results require atraumatic exposure, anatomic reduction, rigid fixation and early mobilization. We describe the use of a temporary external fixator as an intraoperative aid in the open reduction and internal fixation of intra-articular calcaneal fractures. We propose this operative strategy as an option for the treatment of calcaneal fractures. The controlled distractive force provides numerous benefits. These include improved exposure of the subtalar joint, correction of angulation and maintenance of temporary stability prior to definitive fixation. We have found this technique applicable and easily reproducible. PMID:24563983

    The purpose of this study was to measure the tensile properties of fresh human calcaneal (Achilles) tendons. Twenty fresh cadaveric (age range = 57-93 years) bone-Achilles tendon complexes were harvested within 24 hr postmortem. The calcaneus together with 15 cm of the Achilles tendon extending proximally from the insertion on the calcaneus was clamped and biomechanically tested. Each tendon was firmly fixed in clamps in an MTS Systems Corporation MTS testing machine and tension was applied at a displacement rate of 8 cm per minute until the tendon failed. The tensile force and tensile strain (as measured using an extensometer) were recorded and plotted using onboard software. The narrow age range of our donors prevented any meaningful correlation between age and tensile properties; however, the results showed that: 1) the average ultimate tensile strength (UTS) of the human Achilles tendon was 1189 N (range = 360-1,965), 2) there was a correlation between left and right legs for UTS, 3) there was a correlation between left and right legs in regard to cross sectional area, and 4) there was no correlation between UTS and cross-sectional area.

    Quantitative ultrasound (QUS) is a peripheral bone densitometry technique that is rapidly gaining in popularity for the assessment of skeletal status. This study was carried out to examine the effect of anthropometric, dietary, physical activity, and other lifestyle factors on QUS parameters in healthy Greek males of various ages, including children (n=192), adults (n=106), and elderly (n=86) subjects. Calcaneal QUS measurements were performed with the Sahara device (Hologic), which measures broadband ultrasound attenuation (BUA) and speed of sound (SOS) through the os calcis. A composite parameter, the quantitative ultrasound index (QUI), and an estimate of heel bone mineral density (eBMD) were also derived. BUA correlated positively with height, weight, and body mass index, as well as waist and hip circumferences (P<0.001), but this was not the case for SOS. QUI and eBMD were inconsistently related with anthropometric characteristics. Overweight and obese males had significantly higher BUA than normal-weight subjects (P<0.05), but similar SOS, QUI, and eBMD; this held true for all age groups. Boys participating in organized physical activities had significantly higher SOS, QUI, and eBMD than those who did not (P<0.05), although BUA was similar in the two groups; no differences according to organized physical activity were detected in adults and the elderly. On the other hand, adult men devoting at least some time to non-organized physical activities had significantly higher QUS values than their non-exercising peers (P<0.05); no such effects, however, were seen in children and the elderly. Adult men with calcium intakes above 800 mg/day had significantly higher SOS, QUI, and eBMD than those consuming less calcium (P<0.05), and also tended towards higher BUA (P=0.079); no such differences were observed among children and elderly men. The effects of physical activity and calcium intake on heel QUS persisted even after controlling for body size. Overall, body weight was the sole significant positive determinant of BUA (beta=0.373; t=6.589; P<0.001), explaining approximately 14% of the total variance, while age was the sole significant negative determinant of SOS (beta=-0.198; t=-3.321; P=0.001), albeit explaining only less than 4% of the total variance. In conclusion, body size, dietary calcium intake, and physical activity patterns seem to inconsistently and age-dependently influence heel QUS among healthy Greek males in a parameter-specific manner.

    Calcaneal quantitative ultrasound (QUS) is attractive as a prescreening tool for osteoporosis, alternative to dual-energy X-ray absorptiometry. We investigated the literature of the usability of calcaneal QUS. We found large heterogeneity between studies and uncertainty about cutoff, device, and measured variable. Despite osteoporosis-related fractures being a major health issue, osteoporosis remains underdiagnosed. Dual-energy X-ray absorptiometry (DXA) of the hip or spine is currently the preferred method for diagnosis of osteoporosis, but the method is limited by low accessibility. QUS is a method for assessing bone alternative to DXA. The aim of this systematic review was to explore the usability of QUS as a prescreen stratification tool for assessment of osteoporosis. Studies that evaluated calcaneal QUS with DXA of the hip or spine as the gold standard was included. We extracted data from included studies to calculate number of DXAs saved and misclassification rates at cutoffs equal to high sensitivity and/or specificity. The number of DXAs saved and percentage of persons misclassified were measures of usability. We included 31 studies. Studies were heterogeneous regarding study characteristics. Analyses showed a wide spectrum of percentage of DXAs saved (2.7-68.8%) and misclassification rates (0-12.4%) depending on prescreen strategy and study characteristics, device, measured variable, and cutoff. Calcaneal QUS is potentially useful as a prescreen tool for assessment of osteoporosis. However, there is no consensus of device, variable, and cutoff. Overall, there is no sufficient evidence to recommend a specific cutoff for calcaneal QUS that provides a certainty level high enough to rule in or out osteoporosis. Calcaneal QUS in a prescreen or stratification algorithm must be based on device-specific cutoffs that are validated in the populations for which they are intended to be used. PMID:25634771

    The combination of dorsal dislocation of the navicular from the talus and a comminuted fracture of the calcaneus (transcalcaneal talonavicular dislocation) is an unusual and severe injury. It occurs due to a forced plantarflexion of the talar head through the anterior portion of the calcaneum and is usually associated with a potential for skin and neurovascular compromise. Few cases have been reported in the literature. This article reports an unusual case of an open transcalcaneal talonavicular dislocation associated with the presence of a calcaneal comminuted calcaneal fracture. PMID:21944406

    We report the case of a 12-year-old boy with a calcaneal fracture due to a simple supination trauma. As magnetic resonance imaging (MRI) showed a non-displaced extra-articular fracture no surgical treatment was necessary. A conservative therapy using calcaneal fracture orthosis with full weight bearing was carried out. Using this procedure allowed a comfortable means of movement without the need for a plaster cast immobilization or forearm crutches accompanied by a rapid return of the child to the normal daily routine.

    Soft tissue defects of heel region are difficult to repair. The flaps taken from the nonweightbearing area of the sole produce good results. However, these flaps are limited in width and cannot always cover the large defects after excision of malignant tumors. The authors experienced two cases of plantar heel reconstruction with free gracilis musculocutaneous flap after wide excision of malignant skin tumors, and successfully covered the defects. The patients have been free of ulcer for 3 and 1.8 years respectively, after flap transfer. Free gracilis musculocutaneous flap should be added to the techniques for plantar heel reconstruction after wide excision of malignant skin tumors. PMID:8081335

    Objectives: To examine the transfer of abductor digiti minimi (ADM) muscle flaps as a method for preventing wound healing complications in cases of closed calcaneal fractures treated with open reduction and internal fixation (ORIF). Method: Design: Retrospective review. Patients: Twenty-six cases of acute closed calcaneal fracture in patients at risk for serious wound complications or with serious fractures. Intervention: During the ORIF surgery, an ADM muscle flap was removed and used to cover the plate, filling the gap between the plate and skin. Main Outcome Measures: Wound healing rates, postoperative complications, and time to heal. Results: All wounds healed uneventfully, except for one case of minor superficial epithelial necrosis during the early postoperative period, which was treated conservatively. All patients regained ambulatory status with regular foot apparel. At last follow-up, the patients presented no clinical, laboratory, or radiological signs of complications. Conclusions: This ADM muscle flap transfer technique appeared to successfully prevent wound healing complications among patients undergoing ORIF for closed calcaneal fractures. This method offers a promising treatment option for calcaneal fractures in patients at high risk for serious wound complications, and future studies with greater numbers of cases are needed to further investigate its clinical application.

    Subtalar joint middle facet coalitions commonly present in children who have a painful, rigid, pes planovalgus foot type. The middle facet coalition allows rearfoot forces to be distributed medially through the coalition, and this can result in arthritis or lateral tarsal wedging. The senior author has used a wedged bone graft distraction subtalar joint arthrodesis to correct calcaneal valgus and restore the talar height in these patients. The tight, press-fit nature of the tricortical iliac crest allograft provides stability and can negate the need for internal fixation. We retrospectively reviewed 9 pediatric subtalar joint distraction arthrodesis procedures performed on 8 patients during a 6-year period. All patients began weightbearing at 6 weeks after surgery. All patients had osseous union, and no complications developed that required a second surgery. The clinical outcomes, assessed at a mean of 25.5 (range, 6.3 to 75.8) months postoperatively, were satisfactory. The mean American Orthopaedic Foot and Ankle Society score was 90.1 (range, 79 to 94), on a 94-point scale. The wedged distraction arthrodesis technique has not been previously described for correction of pediatric patients with lateral tarsal wedging, but it is an effective option and yields successful outcomes.

    To compare the effect of open reduction internal fixation and conservative treatment combined with open reduction internal fixation for subjects with calcaneal fractures, 130 patients with calcaneal fractures were divided into observation group and control group. Observation group were treated with open reduction internal fixation and conservative treatment, control group treated as open reduction internal fixation. The healing related indicators, daily life activities ability score of observation group after treatment 6 months were significantly higher than that of the control group, there was no significant difference for the healing rate of excellent and good rate, the daily life activities ability score after one and three year between two groups. Open reduction internal fixation combined with conservative treatment in treatment of calcaneal fractures can clear anatomic structure and have fast function recovery. Thus, it should be as the preferred method for the treatment of calcaneal fractures. PMID:25550973

  13. Effects of high heeled shoes wearing experience and heel height on human standing balance and functional mobility.

    PubMed

    2016-02-01

    This study aimed to examine the effects of high heeled shoes (HHS) wearing experience and heel height on human standing balance and functional mobility. Thirty young and healthy females (ten experienced and twenty inexperienced HHS wearers) participated in a series of balance tests when they wore shoes of four different heel heights: 1 cm (flat), 4 cm (low), 7 cm (medium) and 10 cm (high). Experimental results show that regardless of the wearing experience, the heel elevation induces more effort from lower limb muscles (particularly calf muscles) and results in worse functional mobility starting at 7 cm heel height. While the heel height increased to 10 cm, the standing balance also becomes worse. Experienced HHS wearers do not show significantly better overall performance on standing balance and functional mobility than inexperienced controls, even though they have better directional control (76.8% vs. 74.4%) and larger maximum excursion (93.3% vs. 89.7%). To maintain standing balance, experienced wearers exert less effort on tibialis anterior, vastus lateralis and erector spinae muscles at the cost of more intensive effort from gastrocnemius medialis muscle.

    Comminuted, intra-articular calcaneal fractures can cause severe lower extremity impairment and have devastating effects on a patient's well being. Diabetes is a multisystem process that may cause neuropathy and loss of protective sensation further complicating the prognosis. Not all calcaneal fractures are created equal and when considering the patient's overall presentation and extent of injury, the combined approach of internal and external fixation for fracture reduction may be beneficial for restoration of anatomic alignment and function.

  15. The nonlinear finite element analysis and plantar pressure measurement for various shoe soles in heel region.

    PubMed

    Shiang, T Y

    1997-10-01

    The most influential factor contributing to foot and shoe comfort is underfoot cushioning. The shock absorbing ability of footwear in the heel area is of particular importance in reducing the impact load during athletic activities and in therapeutic footwear prescribed for heel pain. Furthermore, foot care for foot problem patients is an important part of treatment and educational programs. Therefore, a well-designed sport shoe which can provide comfort and protection is essential. In order to design a functional shoe, biomechanics and other new technologies should be considered, and the design process should be examined in the biomechanics laboratory over and over. The design process requires too much time and effort since the entire experimental and test work can only be done after the prototype is manufactured. Therefore, this study tried to introduce the Finite Element Method (FEM) into the shoe design process by building a three-dimensional FE model with various shoe soles and loading conditions. The material properties of shoe materials were tested using an Instron Testing Machine. An in-shoe pressure insole was used to measure the plantar pressure in different ambulation conditions with various shoe constructions. The subject for this study was a healthy young male without any foot problem. The average plantar pressures obtained from approximately 50 steps in the heel region for each of the various conditions were collected. The results showed that the mean peak plantar pressure of the running situation was significantly higher than that of the walking situation as predicted, and that the insole could provide better cushioning compared to the other shoe constructions. The stress strain relationship for shoe materials was approximated better by a second-order nonlinear curve according to the Instron test. The results of the finite element method suggested that only the second-order nonlinear stress strain curve could correctly describe the shoe material, which also confirmed a potential valuable role for FEM in designing functional shoes.

    Objective: In the surgery of calcaneal fracture, whether the sustentaculum tali screw should always be placed is widely controversial. The aim of this study was to explore the necessity and function of the sustentaculum tali screw placement for the treatment of Sanders type II calcaneal fracture. Methods: The finite element analysis was used in this study. After the establishment of the finite element model of Sanders type II calcaneal fracture, the two internal fixation simulations were designed. In one model, the AO calcaneal plate was simulated on the lateral side of the calcanues with 7 screws being fixated at different position of the plate. In the other model, the calcaneus was fixated with the same AO calcaneal plate together with an additional screw being infiltrated into the sustentaculum tali. The two models were simulated under the same loading and the displacement of the fracture line and the stress distribution in the two models were calculated respectively. Results: The maximum principal stress focused on the cortical bone of sustentaculum tali in both the models under the same loading. The displacement of the fracture line, the maximum principal stress of calcaneus and internal fixation system in the model with sustentaculum screw fixation were smaller than that in the model without sustentaculum screw fixation. The stress in the model with sustentaculum screw fixation was more dispersed. Conclusions: The placement of sustentaculum tali screw is essential for fixation of type II calcaneal fracture to achieve the biomechanical stability. PMID:25225534

    Offloading heel ulcers is a challenging task because strategies deemed to be most optimal from a medical perspective may be unacceptable to patients. Observed adverse dressing events and problems with offloading devices led to a pilot study and subsequent change in practice at the authors' Foot and Leg Ulcer Clinic. Starting in 2004, patients requiring offloading received a nonremovable padded heel dressing (PHD) that was changed twice a week by the visiting nurse. A retrospective quality improvement review was conducted to compare outcomes, nursing visits, and nursing visit costs for 40 consecutive patients with heel ulcers treated at this clinic with a nonremovable PHD (n = 20) or without a PHD (n = 20) between January 20, 2001 and December 31, 2006. Patient demographic data, relevant comorbidities, wound depth, weeks of care, adverse events, and treatment-related narrative comments were abstracted from patient records. Relevant comorbidities were similar in both groups. The PHD group was younger (average age of 74.6 [range 35-91] years) compared to PHD nonuse group (average age 79.5 [range 25-95] years; P less than 0.04). The PHD group required fewer total weeks of care compared to the nonuse group (368 versus 527 weeks, respectively; P less than 0.001), and average duration of clinic treatment in the PHD group was 18.40 (range 5-51) weeks versus 40.54 (range 6-88) weeks in the nonuse group. The PHD group had fewer total nursing visits (736 versus 1,581, P less than 0.001); the average number of nursing visits for the PHD was 36.80 (range 10-102) compared to 121.61 (range 18-264) for the nonuse group. Nursing visit costs were lower for PHD users ($114,080 versus $245,055, P less than 0.001), and the cost-efficiency ratio was less than one third (1:3.3) of PHD nonuse for the average heel ulcer. All 20 patients in the PHD use group had wound closure compared with the PHD nonuse group, in which 13 out of 20 wounds closed, 3 amputations were performed, and 4 patients were lost to review (P less than 0.000). No adverse events were reported in the records of the PHD use group; the PHD nonuse group reported periwound maceration, skin stripping, pressure injury, and sensitivity. Patient and nurse feedback identified pain relief, improved mobility, easy technique, low cost, and reduced workload as benefits of PHD. The results of this quality improvement review warrant a prospective clinical study to examine the efficacy, effectiveness, and cost-effectiveness of PHD for the care of patients with heel ulcers.

  18. Heel reconstruction with free instep flap: a case report

    PubMed Central

    2014-01-01

    Introduction Reconstruction of weight-bearing heel defects remains a challenge because of the unique characteristics of the plantar skin. Though numerous surgical reconstructive options have been reported, the instep flap represents an ideal option and seems to be more acceptable to patients than others. However, when the heel defect expands to the instep area, the ipsilateral instep is not available for flap elevation. A free instep flap harvested from the contralateral foot can be a good solution, but this method has been scarcely reported. Case presentation A 41-year-old Asian man presented to our institution with a soft-tissue lesion in the weight-bearing heel and instep area. His heel was reconstructed with a free instep flap from the other foot, end-to-side anastomosis of its medial plantar artery to the recipient posterior tibial artery and end-to-side coaptation of the cutaneous sensory fascicles of the flap to the medial plantar nerve. Conclusion The flap survived successfully, and no ulceration occurred in the flap. At the last follow-up appointment at 30 months post-surgery, a very good functional and aesthetic outcome was verified, indicating that the suggested approach may prove to be the treatment of choice in selected cases of weight-bearing heel reconstruction.

[Subjects and Methods] A single-subject design was used, 15 healthy women wearing revised high-heeled shoes and general high-heeled shoes in a random order. The foot pressure ratio and static balance scores during standing were measured using a SpaceBalance 3D system. [Results] Forefoot and rearfoot pressures were significantly different between the 2 types of high-heeled shoes. Under the 3 conditions tested, the static balance score was higher for the revised high-heeled shoes than for the general high-heeled shoes, but this difference was not statistically significant. [Conclusion] Revised high-heeled shoes are preferable to general high-heeled shoes, as they result in normalization of normalized foot pressure and a positive effect on static balance. PMID:25995572

    Osteomyelitis is a bone infection caused by bacteria or other germs. Gram-positive cocci are the most common etiological organisms of calcaneal osteomyelitis; whereas, non-tuberculous mycobacteria (NTM) are rarely documented. We reported a case of NTM calcaneal osteomyelitis in a 51-year-old female patient. She had been previously treated in many local clinics with multiple local steroid injection over 50 times and extracorporeal shock-wave therapy over 20 times with the impression of plantar fasciitis for 3 years prior. Diagnostic workup revealed a calcaneal osteomyelitis and polymerase chain reaction assay on bone aspirate specimens confirmed the diagnosis of non-tuberculous mycobacterial osteomyelitis. The patient had a partial calcanectomy with antitubercular therapy. Six months after surgery, a follow-up magnetic resonance imaging showed localized chronic osteomyelitis with abscess formation. We continued anti-tubercular therapy without operation. At 18-month follow-up after surgery and comprehensive rehabilitation therapy, she was ambulating normally and able to carry out her daily activities without any discomfort. PMID:26949685

    Objective To demonstrate the bifurcation pattern of the tibial nerve and its branches. Methods Eleven legs of seven fresh cadavers were dissected. The reference line for the bifurcation point of tibial nerve branches was an imaginary horizontal line passing the tip of the medial malleolus. The distances between the reference line and the bifurcation points were measured. The bifurcation branching patterns were categorized as type I, the pattern in which the medial calcaneal nerve (MCN) branched most proximally; type II, the pattern in which the three branches occurred at the same point; and type III, in which MCN branched most distally. Results There were seven cases (64%) of type I, three cases (27%) of type III, and one case (9%) of type II. The median MCN branching point was 0.2 cm (range, -1 to 3 cm). The median bifurcation points of the lateral plantar nerves and inferior calcaneal nerves was -0.6 cm (range, -1.5 to 1 cm) and -2.5 cm (range, -3.5 to -1 cm), respectively. Conclusion MCN originated from the tibial nerve in most cases, and plantar nerves were bifurcated below the medial malleolus. In all cases, inferior calcaneal nerves originated from the lateral plantar nerve. These anatomical findings could be useful for performing procedures, such as nerve block or electrophysiologic studies. PMID:25750872

    The accurate assessment of skeletal maturity is essential in the management of orthopaedic conditions in the growing child. In order to identify the time of peak height velocity (PHV) in adolescents, two systems for assessing skeletal maturity have been described recently; the calcaneal apophyseal ossification method and the Sanders hand scores. The purpose of this study was to compare these methods in assessing skeletal maturity relative to PHV. We studied the radiographs of a historical group of 94 healthy children (49 females and 45 males), who had been followed longitudinally between the ages of three and 18 years with serial radiographs and physical examination. Radiographs of the foot and hand were undertaken in these children at least annually between the ages of ten and 15 years. We reviewed 738 radiographs of the foot and 694 radiographs of the hand. PHV was calculated from measurements of height taken at the time of the radiographs. Prior to PHV we observed four of six stages of calcaneal apophyseal ossification and two of eight Sanders stages. Calcaneal stage 3 and Sanders stage 2 was seen to occur about 0.9 years before PHV, while calcaneal stage 4 and Sanders stage 3 occurred approximately 0.5 years after PHV. The stages of the calcaneal and Sanders systems can be used in combination, offering better assessment of skeletal maturity with respect to PHV than either system alone. PMID:26637689

    Placement of a screw from the lateral wall of the calcaneus into the constant sustentaculum tali fragment can be difficult when surgically repairing a calcaneal fracture. This screw serves to compress the fracture fragments and support the posterior facet. This difficulty results from the small landing zone of the sustentaculum tali with its nearby vulnerable soft tissue structures. We present an anatomic study of 10 cadavers to determine a starting point and angle of screw advancement when placing a constant fragment screw. PMID:25441853

    Surgical correction of hindfoot varus is frequently performed with a lateral displacement calcaneal osteotomy. It has rarely been associated with iatrogenic tarsal tunnel syndrome in patients with pre-existing neurological disease. We report the first case of acute postoperative tarsal tunnel syndrome in a neurologically intact patient with post-traumatic hindfoot varus. Early diagnosis and emergent operative release afforded an excellent clinical outcome. Imaging studies can help outrule a compressive hematoma and assess for possible nerve transection; however it is paramount that a high index of suspicion is utilized with judicious operative intervention to minimize long-term sequelae.

    Abstract Intravascular myopericytoma (IVMP), regarded as a variant of myopericytoma, is a rare tumor. Very few cases have been described, none in the foot. The first case of IVMP located in the heel of the foot is described in this article. A literature review is reported of all cases of IVMP published in the English literature. A 48-year-old man possessed an IVMP on the heel of the right foot. The physical examination and histopathological and ultrasound studies are described. The literature review yielded 5 cases of IVMP, 2 of which were in the thigh and 1 each in the oral mucosa, the periorbital region, and the leg. The possibility that these lesions may be malignant suggests that the histopathological study of vascular tumors should include immunohistochemical tests. PMID:25789958

    A system and method for providing nearly instantaneous power in a fuel cell vehicle. The method includes monitoring the brake pedal angle and the accelerator pedal angle of the vehicle, and if the vehicle driver is pressing both the brake pedal and the accelerator pedal at the same time and the vehicle is in a drive gear, activating a heel and toe mode. When the heel and toe mode is activated, the speed of a cathode compressor is increased to a predetermined speed set-point, which is higher than the normal compressor speed for the pedal position. Thus, when the vehicle brake is removed, the compressor speed is high enough to provide enough air to the cathode, so that the stack can generate nearly immediate power.

    Knee osteoarthritis (OA), a leading cause of disability, is more prevalent in women than men. Wearing high heeled shoes has been implicated as a potential contributing factor for the higher lifetime risk of osteoarthritis in women. This study tests the hypotheses that changes to knee kinematics and kinetics observed during high heeled walking increase in magnitude with increasing heel height and are accentuated by a 20% increase in weight. Fourteen healthy females were tested using marker-based gait analysis in combinations of footwear (flat athletic shoe, 3.8 cm and 8.3 cm heeled shoes) and weight (with and without 20% bodyweight vest). At preferred walking speed, knee flexion angle at heel-strike and midstance increased with increasing heel height and weight. Maximum knee extension moment during loading response decreased with added weight; maximum knee extension moment during terminal stance decreased with heel height; maximum adduction moments increased with heel height. Many of the changes observed with increasing heel height and weight were similar to those seen with aging and OA progression. This suggests that high heel use, especially in combination with additional weight, may contribute to increased OA risk in women. PMID:25532875

    Coverage of soft tissue defects of the heel has been a challenge to reconstructive surgeons in the past. The medial plantar artery flap has facilitated heel coverage since its development in the 1980s. This was a prospective study in 2 centers assessing the complications and durability of this flap primarily in patients with sensory impairment. All patients but 1 had chronic plantar ulceration due to sensory loss, and 5 patients also had developed squamous cell carcinoma. Fifty-one flaps were carried out in 48 patients. One flap underwent necrosis, and delayed healing was seen in 4 cases. Total flap survival was 98%. Minor revision of the flap or its pedicle was required in 3 cases. With a mean follow-up of 14 months, there were recurrences of ulceration in 7 feet (14%). The relevant literature is reviewed. The medial plantar artery flap is a reliable flap for heel coverage in both our centers and others. It is durable and long lasting even in insensate. PMID:17122553

    The shock absorbing characteristics of the heel pad in vivo were examined in two groups of active elderly individuals whose ages ranged between 60 and 67 years (n = 10) and between 71 and 86 years (n = 10). For comparative purposes, young adults (n = 10) aged between 17 and 30 years were also examined. A free-fall impact testing device which consisted of an instrumented shaft (mass 5 kg), accelerometer and position detection transducer was used to obtain deceleration and deformation of the heel during impact. The data were obtained from impact velocities of 0.57 m.s-1 (slow) and 0.94 m.s-1 (fast). Peak values of the deceleration and deformation, as well as the time to these peaks from onset of impact, and energy absorption were evaluated. At the slow impact velocity, no age effect was found for the parameters examined except for the energy absorption. At the fast impact velocity, there was higher peak deceleration and smaller deformation for the elderly than for the younger adults. The energy absorbed was less for the elderly than for the younger adults. It was concluded that the capacity for shock absorbency of the heel pad declines with age. PMID:8803499

    The paper presents a theory of fixation failure and loosening in cemented total hip prostheses and proceeds to investigate this using an experimentally validated finite element model and two prosthesis types, namely the Charnley and the C-Stem. The study investigates the effects of retroversion torque occurring at heel-strike in combination with a loss of proximal cement/bone support and distal implant/cement support with a good distal cement/bone interface. A 3D finite element model was validated by comparison of femoral surface strains with those measured in an in vitro experimental simulation using an implanted Sawbone femur loaded in the heel-strike position and including a simplified representation of muscle forces. Results showed that the heel-strike position applies a high retroversion torque to the femoral stem that when combined with proximal debonding of the cement/bone interface and distal debonding of the implant/cement interface increases the strain transfer to the cement that may ultimately lead to the breakdown of the cement mantle leading on to osteolysis and loosening of the prostheses. Experimental fatigue testing of the implanted Charnley stem in a Sawbone femur produced cracks within the cement mantle that were located in positions of maximum stress supporting the finite element analysis results and theory of failure.

    The objective was to report on a rare case of chondrosarcoma of the bones of the foot, and specifically the calcaneus. The patient was a 30-year-old woman with a complaint of painless nodulation on the lateral face of the calcaneus, which she had had for around eight years, which then started to present significant pain. Radiography showed a tumor with imprecise limits, compromising the calcaneus, talus and lateral malleolus. The lesion had a destructive, aggressive and osteolytic appearance, with invasion of the surrounding soft tissues and the presence of points of calcification. Amputation was performed in the middle third of the right lower leg, with a histological diagnosis of chondrosarcoma. The case evolved with local recurrence of the tumor formation and subsequent amputation in the middle third of the right thigh. One year after the second amputation, the patient evolved with metastasis from the chondrosarcoma in soft tissues throughout the body and in the lungs, and she died one year and ten months after the diagnosis was made. Chondrosarcomas that involve the calcaneus are rare in young adults, with few reports in the literature. For this reason, the present report becomes important in that it shows that even though this is a rare condition, it is present in our environment. Early investigation is essential, especially by means of imaging examinations, with the aim of diminishing the chances of malignant transformation and consequent complications, so as to avoid death.

    OBJECTIVES: Evaluate physiological and behavioral parameters to verify if newborns feel pain when submitted to gastric suctioning. METHODS: 50 healthy newborns over 33 weeks gestational age, weighing more than 1999g, were submitted to gastric suctioning, randomly selected, and divided into two groups: Friction/Lancing and Lancing/Friction. The newborns were assessed through the Neonatal Infant Pain Scale (NIPS) (0-7, pain>3) by two independent observers in three different moments: one minute before, during, and one minute after gastric suctioning, heel lancing and foot friction, with simultaneous monitoring of heart rate, respiratory frequency, and hemoglobin oxygen saturation. RESULTS: The respiratory frequency only decreased during gastric suctioning (P=0.004). The heart rate was lower during gastric suctioning (P<0.0001), during the heel lacing procedure in the Friction/Lancing group (P=0.01), and during friction in the Friction/Lancing group (P=0.022). The hemoglobin oxygen saturation suffered no alterations during the three procedures. The results obtained through NIPS revealed that both groups felt pain during gastric suctioning and heel lancing, and did not feel pain during friction (P<0.0001). CONCLUSION: During the gastric suctioning procedure, newborns responded as if it were a painful stimulus. Physiological alterations were neither specific nor sensitive to pain assessment in newborn infants. PMID:14647841

    The aim of this study is to determine whether surgery offers protection against early subtalar arthrodesis in displaced intraarticular calcaneal fractures. Systematic review and meta-analysis: searches of electronic databases 1980 to August 2014, checking of reference lists, hand searching of journals, and contact with experts. Randomized controlled trials (RCTs) in which surgical treatment was compared with nonsurgical treatment of displaced intra-articular calcaneal fractures from 1980 to 2014. The modified Jadad scale was used for trial quality and effective data were pooled for meta-analysis. Study results related to early subtalar arthrodesis were extracted and risk assessment was combined with surgical treatment and nonsurgical treatment. The primary analysis included 4 studies and 966 participants. The estimated overall risk ratio was 4.40 (95% confidence interval 2.67-7.39), indicating the incidence of early subtalar arthrodesis in nonsurgical group is 4.4 times the surgical group. The results showed that surgical treatment was superior to nonsurgical treatment in protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures (Z = 5.600, P < 0.001).Surgery offers protection against early subtalar arthrodesis in displaced intra-articular calcaneal fractures.

    Objective To ascertain whether the number of screws or pins placed in the calcaneus might increase the risk of injury when three different techniques for treating calcaneal fractures. Method 126 radiographs of patients who suffered displaced calcaneal fractures were retrospectively analyzed. Three surgical techniques were analyzed on an interobserver basis: 31 radiographs of patients treated using plates that were not specific for the calcaneus, 48 using specific plates and 47 using an external fixator. The risk of injury to the anatomical structures in relation to each Kirschner wire or screw was determined using a graded system in accordance with the Licht classification. The total risk of injury to the anatomical structures through placement of more than one wire/screw was quantified using the additive law of probabilities for the product, for independent events. Results All of the models presented high explanatory power for the risk evaluated, since the coefficient of determination values (R2) were greater than 98.6 for all the models. Therefore, the set of variables studied explained more than 98.6% of the variations in the risks of injury to arteries, veins or nerves and can be classified as excellent models for prevention of injuries. Conclusion The risk of injury to arteries, veins or nerves is not defined by the total number of pins/screws. The region and the number of pins/screws in each region define and determine the best distribution of the risk. PMID:27069891

    One of the reasons that high heels may contribute to the formation of halux valgus is that the wearers pronate during propulsion. This pilot study was performed to determine whether relocation of the heel under the counter of a fashion high-heeled pump could change the degree of pronation of the foot during the gait cycle. The authors report that more foot stability was experienced by the subjects when the center of the heel was offset between 2 and 4 mm medial to the center of the heel counter. This study is designed to promote further research into whether the shoe industry should change the design parameters of high-heeled fashion shoes in order to improve foot function. PMID:1875295

    Background Calcaneus has the most fracture prevalence among tarsal bones. About 3/4 of calcaneal fractures are intra-articular fractures with displacement. The majority of calcaneal fractures occur in 21 - 35 year old young men, and that are mostly active people, these fractures cause complete disability for 15 months. Moreover, inappropriate treatment leads to lots of social and economical damages. Objectives In this study we compared the incidence and the severity of peroneal tenosynovitis as a complication of non-operative and operative treatment of intra-articular calcaneal fractures. In this study, some other complications of this fracture were also analyzed and the prevalence of the complication was higher in non-operated patients. Patients and Methods A total of 140 patients with intra-articular calcaneal fracture were analyzed prospectively. These patients were divided into 2 groups: operated group and non-operated group. Results In non-operated group (56 patients), 22 patients were complicated by peroneal tenosynovitis. In operated group (84 patients), 8 patients had the same complication. Statistical analysis revealed that the prevalence, and the severity of this complication in the mentioned groups had a meaningful difference. The results in operated group were much better than the non-operated one. Conclusions Although some of the orthopedic surgeons are not interested to manage these fractures surgically and most of them treat these cases conservatively (casting, etc.), in most displaced intra-articular calcaneal fractures, surgical treatment is the method of choice. Moreover, in non-surgical treatment the prevalence of these complications among the patients is more and as a result, inevitable social, occupational and familial damages occur. PMID:24693362

    In spite of ill-effects of high heel shoes, they are widely used for women. Hence, it is essential to understand the load transfer biomechanics in order to design better fit and comfortable shoes. In this study, both experimental measurement and finite element analysis were used to evaluate the biomechanical effects of heel height on foot load transfer. A controlled experiment was conducted using custom-designed platforms. Under different weight-bearing conditions, peak plantar pressure, contact area and center of pressure were analyzed. A three-dimensional finite element foot model was used to simulate the high-heel support and to predict the internal stress distributions and deformations for different heel heights. Results from both experiment and model indicated that heel elevations had significant effects on all variables. When heel elevation increased, the center of pressure shifted from the midfoot region to the forefoot region, the contact area was reduced by 26% from 0 to 10.2 cm heel and the internal stress of foot bones increased. Prediction results also showed that the strain and total tension force of plantar fascia was minimum at 5.1 cm heel condition. This study helps to better understand the biomechanical behavior of foot, and to provide better suggestions for design parameters of high heeled shoes.

    Neonates in the neonatal intensive care unit experience painful procedures. Over the last 10 years, investigators have examined several pharmacologic and nonpharmacolgic treatment strategies to decrease or eliminate the pain associated with mechanical ventilation, endotrachial intubation, insertion of percutaneous or central venous lines, heel stick, and venipuncture. These procedures and others are addressed as well as the reported severity of pain associated with these procedures. Progress has been made in the past decade to establish evidence-based treatments that will help the clinician more effectively relieve neonatal stress and pain when performing many routine procedures.

    Given the high rates of wound complications with a standard lateral extensile incision, small dual incision techniques might result in less soft tissue destruction. The goal of the present study was to compare the biomechanical performance between a single locking plate and a dual locking plating system for an intra-articular calcaneal fracture model. A Sanders IIB type joint depression calcaneal fracture was created in 10 paired, fresh-frozen, cadaveric calcanei (age 47 ± 12, range 35 to 78 years). The calcanei of each pair were randomly assigned for fixation using either a lateral locking reconstruction plate or lateral and medial locking reconstruction plates. The specimens were axially loaded in cyclic fashion for 1000 cycles, followed by load to failure. The relative fragment movement was monitored optically in both the sagittal and the coronal planes. The amount of overall construct displacement increased with cycling, although no difference was found between the plating techniques. For fragment movement during cycling, the lateral joint fragment migrated anteroinferiorly along the fracture line relative to the tuberosity fragment for dual plated specimens by a small, but statistically significant, amount. This same translation was smaller for lateral plated specimens but was not found to be significant. During load to failure testing, no statistically significant differences were found for construct stiffness. A tendency was seen toward more interfragmentary motion in the sagittal plane (lateral joint fragment movement relative to the fracture line), with less movement overall in the coronal plane (anterior fragment translation and twist) for dual plating, although the difference from the lateral plate was not statistically significant. The present study demonstrated that for this calcaneal fracture model, the dual plating technique experienced a small amount of fragment translation during cycling that was significantly different statistically from that with lateral plating but was not clinically relevant. During the load to failure, the dual plating technique was comparable to the lateral plate. Thus, dual plating could be a viable biomechanical option for fracture reduction if avoidance of a large extensile lateral approach associated with lateral plating is warranted. PMID:25960057

    To determine the factors in daily physical activity that influence the mineral density of the calcaneus, we recorded walking steps and the type and duration of exercise in 43 healthy 26-to 51-yr-old men. Areal (g/sq cm) calcaneal bone mineral density (CBMD) was measured by single energy x-ray densitometry. Subjects walked a mean (+/- SD) of 7902(+/-2534) steps per day or approximately 3.9(+/-1.2) miles daily. Eight subjects reported no exercise activities. The remaining 35 subjects spent 143(2-772) (median and range) min/wk exercising. Twenty-eight men engaged in exercise activities that generate single leg peak vertical ground reaction forces (GRF(sub z)) of 2 or more body weights (high loaders, HL), and 15 reported exercise or daily activities that typically generate GRF(sub z) less than 1.5 body weights (low loaders, LL). CBMD was 12% higher in HL than LL (0.668 +/- 0.074 g/sq cm vs 0.597 +/- 0.062 g/sq cm, P less than 0.004). In the HL group, CBMD correlated to reported minutes of high load exercise (r = 0.41, P less than 0.03). CBMD was not related to the number of daily walking steps (N = 43, r = 0.03, NS). The results of this study support the concept that the dominant factor in daily physical activity relating to bone mineral density is the participation in site specific high loading activities, i.e., for the calcaneus, high calcaneal loads.

    Computational fluid dynamics methods were used to recommend a slurry pump operational strategy for sludge heel removal in Tank 8. Flow patterns calculated by the model were used to evaluate the performance of various combinations of operating pumps and their orientation. The models focused on removal of the sludge heel located at the east side of Tank 8 using the four existing slurry pumps. The models and calculations were based on prototypic tank geometry and expected normal operating conditions as defined by Waste Removal Closure (WRC) Engineering. The calculated results demonstrated that for pump speeds higher than 1800 rpm and at a 130 inch liquid level, a recommended orientation of the slurry pumps could be provided, based on a minimum sludge suspension velocity of 2.27 ft per sec. Further results showed that the time to reach a steady-state flow pattern was affected by both the tank level and the pump speed. Sensitivity studies showed that for a given pump speed, a higher tank level and a lower pump nozzle elevation would result in better performance in suspending and removing the sludge. The results also showed that the presence of flow obstructions were advantageous for certain pump orientations.

    The setting for this quality improvement initiative designed to reduce the prevalence of facility-acquired heel pressure ulcers was a regional, acute-care, 490-bed facility in Ontario, Canada, responsible for dialysis, vascular, and orthopedic surgery. An interdisciplinary skin and wound care team designed an evidence-based quality improvement initiative based on a systematic literature review and standardization of heel offloading methods. The prevalence of heel pressure ulcers was measured at baseline (immediately prior to implementation of initiative) and at 1 and 4 years following implementation. The prevalence of facility-acquired heel pressure ulcers was 5.8% when measured before project implementation. It was 4.2% at 1 year following implementation and 1.6% when measured at the end of the 4-year initiative. Outcomes demonstrate that the initiative resulted in a continuous and sustained reduction in facility-acquired heel pressure ulcer incidence over a 4-year period. PMID:26473635

    Wearing high heel shoes has been associated with an increased potential for slips and falls. The association between wearing high heels and the increased potential for slipping suggests that the friction demand while wearing high heels may be greater when compared to wearing low heel shoes. The purpose of this study was to determine if heel height affects utilized friction (uCOF) during walking. A secondary purpose of this study was to compare kinematics at the ankle, knee, and hip that may explain uCOF differences among shoes with varied heel heights. Fifteen healthy women (mean age 24.5±2.5yrs) participated. Subjects walked at self-selected velocity under 3 different shoe conditions that varied in heel height (low: 1.27cm, medium: 6.35cm, and high: 9.53cm). Ground reaction forces (GRFs) were recorded using a force platform (1560Hz). Kinematic data were obtained using an 8 camera motion analysis system (120Hz). Utilized friction was calculated as the ratio of resultant shear force to vertical force. One-way repeated measures ANOVAs were performed to test for differences in peak uCOF, GRFs at peak uCOF and lower extremity joint angles at peak uCOF. On average, peak uCOF was found to increase with heel height. The increased uCOF observed in high heel shoes was related to an increase in the resultant shear force and decrease in the vertical force. Our results signify the need for proper public education and increased footwear industry awareness of how high heel shoes affect slip risk. PMID:21536444

    Intra-articular fractures of calcaneum are known to be difficult to manage and lead to multiple complications including subtalar arthritis and malunion. However, non-union of calcaneum is rarely encountered. Only a total of six studies reporting on 12 patients could be found on reviewing the available literature (English language only). One such case of non-union of calcaneal fracture and its successful management is being reported in this case report. In addition, extremely limited literature available on calcaneal non-union is also briefly reviewed. Role of subtalar arthrodesis with internal fixation of fracture and bone grafting for successful management of this rare complication is highlighted along with the possibility of under-reporting of this relatively unknown complication.

    Purpose This study was designed to evaluate the mid-term results and efficacy of subtalar distraction double bone-block arthrodesis for calcaneal malunion. Materials and Methods From January 2004 to June 2007, we operated on 6 patients (10 cases). There were 5 males (9 cases) and 1 female (1 case), four of which presented with bilateral calcaneal malunion. Seven cases were operated on initially. The period between initial injury and arthrodesis was 23 months, and the average follow up period was 58 months. In operation, we applied an extensile lateral approach and arthrodesis was performed through a tricortical double bone-block and cannulated screws. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT were examined to assess union and various parameters. Results The mean age of the patients was 41 years. All cases achieved radiologic union at the final follow-up. The mean AOFAS Ankle-Hindfoot scale (maximum of 94 points) increased from 43.3 points preoperatively to 85.4 points at the final follow-up. The radiologic analysis of the pre- and postoperative standing lateral radiographs showed improvements of 5.6 mm in talo-calcaneal height, 1.8° in talocalcaneal angle, 5.1° in talar declination angle and 5.3° in talo-first metatarsal angle. Conclusion Subtalar distraction two bone-block arthrodesis provides overall good results not only in the short term but also the mid-term with significant improvement in clinical and radiologic outcomes. This procedure warrants consideration for managing calcaneal malunion with loss of height and subtalar arthritis. PMID:24954341

    This study investigates differences and associations between urinary mineral concentrations and calcaneal bone measures assessed by quantitative ultrasonography (QUS) in 4322 children (3.1-11.9 years, 50.6% boys) from seven European countries. Urinary mineral concentrations and calcaneal QUS parameters differed significantly across countries. Clustering revealed a lower stiffness index (SI) in children with low and medium urinary mineral concentrations, and a higher SI in children with high urinary mineral concentrations. Urinary sodium (uNa) was positively correlated with urinary calcium (uCa), and was positively associated with broadband ultrasound attenuation and SI after adjustment for age, sex and fat-free mass. Urinary potassium (uK) was negatively correlated with uCa but positively associated with speed of sound after adjustment. No association was found between uCa and QUS parameters after adjustment, but when additionally adjusting for uNa, uCa was negatively associated with SI. Our findings suggest that urinary mineral concentrations are associated with calcaneal QUS parameters and may therefore implicate bone properties. These findings should be confirmed in longitudinal studies that include the food intake and repeated measurement of urinary mineral concentrations to better estimate usual intake and minimize bias.

    This study investigates differences and associations between urinary mineral concentrations and calcaneal bone measures assessed by quantitative ultrasonography (QUS) in 4322 children (3.1–11.9 years, 50.6% boys) from seven European countries. Urinary mineral concentrations and calcaneal QUS parameters differed significantly across countries. Clustering revealed a lower stiffness index (SI) in children with low and medium urinary mineral concentrations, and a higher SI in children with high urinary mineral concentrations. Urinary sodium (uNa) was positively correlated with urinary calcium (uCa), and was positively associated with broadband ultrasound attenuation and SI after adjustment for age, sex and fat-free mass. Urinary potassium (uK) was negatively correlated with uCa but positively associated with speed of sound after adjustment. No association was found between uCa and QUS parameters after adjustment, but when additionally adjusting for uNa, uCa was negatively associated with SI. Our findings suggest that urinary mineral concentrations are associated with calcaneal QUS parameters and may therefore implicate bone properties. These findings should be confirmed in longitudinal studies that include the food intake and repeated measurement of urinary mineral concentrations to better estimate usual intake and minimize bias.

    [Purpose] This study aimed to provide a predictable evaluation method for the progression of scoliosis in adolescents based on quick and reliable measurements using the naked eye, such as the calcaneal valgus angle of the foot, which can be performed at public facilities such as schools. [Subjects and Methods] Idiopathic scoliosis patients with a Cobb’s angle of 10° or more (96 females, 22 males) were included in this study. To identify relationships between factors, Pearson’s product-moment correlation coefficient was computed. The degree of scoliosis was set as a dependent variable to predict thoracic and lumbar scoliosis using ankle angle and physique factors. Height, weight, and left and right calcaneal valgus angles were set as independent variables; thereafter, multiple regression analysis was performed. This study extracted variables at a significance level (α) of 0.05 by applying a stepwise method, and calculated a regression equation. [Results] Negative correlation (R=−0.266) was shown between lumbar lordosis and asymmetrical lumbar rotation angles. A correlation (R=0.281) was also demonstrated between left calcaneal valgus angles and asymmetrical thoracic rotation angles. [Conclusion] Prediction of scoliosis progress was revealed to be possible through ocular inspection of the calcaneus and Adams forward bending test and the use of a scoliometer. PMID:26834376

    Empty UF{sub 6} cylinders containing heel material were found to emit radiation levels in excess of 200 mr/hr, the maximum amount stated in ORO-651. The radiation levels were as high as 335 mr/hr for thick wall (48X and 48Y) cylinders and 1050 mr/hr for thin wall (48G and 48H) cylinders. The high readings were found only on the bottom of the cylinders. These radiation levels exceeded the maximum levels established in DOT 49 CFR, Part 173.441 for shipment of cylinders. Holding periods of four weeks for thick-wall cylinders and ten weeks for thin-wall cylinders were established to allow the radiation levels to decay prior to shipment.

    Prior research revealed activation differences between the medial (MG) and lateral (LG) gastrocnemius when performing heel raise exercise with neutral (N), internally-rotated (IR) and externally-rotated (ER) foot positions. Studying underlying biomechanics may help explain activation differences. The purpose was to compare ankle (AN), knee (KN), and hip (HI) contributions (initial joint angles) to attaining each initial foot position, ankle flexion-extension range of motion, ankle mechanical energy expenditure, repetition time, and percent cycle concentric-eccentric transition between N, IR, and ER foot positions. Twenty healthy subjects (11 male, 9 female) with resistance training experience performed twelve repetitions of free-weight (135% body mass) heel raise exercise using N, IR and ER foot positions in a counterbalanced order. Forefeet were elevated .05m onto separate forceplates. Electromagnetic sensors secured along dominant lower limb recorded kinematic data. Dependent variables were averaged across five selected repetitions. No significant differences existed for repetition time (P=.209), percent cycle concentric-eccentric transition (P=.668), ankle mechanical energy expenditure (P=.590), and ankle flexion-extension range of motion (P=.129) between foot positions. Post hoc comparison of a significant joint by foot position interaction (P<.001) demonstrated IR>N>ER for the initial HI and KN angles, whereas for AN, ER>IR and N. Between joints: AN

    Objective—To compare by cross sectional study the quantitative heel ultrasound (QUS) variables broadband ultrasound attenuation (BUA) and velocity of sound (VOS) in male powerlifters and controls. Methods—Twenty four powerlifters and 21 sedentary male controls were recruited to the study. All the powerlifters were members of the British Drug Free Powerlifting Association and actively competing at the time of the study. A questionnaire was completed by all those entered into the study. This included a history of smoking and an estimation of daily intake of alcohol and calcium. For the powerlifters, the number of years spent training and time spent training each week was also recorded. The QUS variables of all powerlifters and controls were measured using a Cubaclinical II (McCue) ultrasound scanner. Results—The powerlifters had been training for a mean (SEM) of 10.6 (1.6) years and they trained for 6.5 (0.4) hours a week. The powerlifters were non-significantly older and had a significantly higher body mass index (BMI) than the controls. Calcium intake and consumption of alcohol and tobacco were similar in the two groups. The mean BUA in the powerlifters was a significant 9.5% (95% confidence interval 0.7 to 18.3%) higher than the controls (105 v 96 dB/MHZ) and 15.6% (95% confidence interval 6.8 to 24.4%) higher after adjustment using analysis of covariance for age, BMI, and alcohol and tobacco consumption (108 v 93 dB/MHZ). The mean VOS was similar in the two groups, but after adjustment it was significantly higher in the powerlifters (1671 v 1651 m/s, p<0.01). Conclusions—The study shows the ability of heel ultrasound to discriminate between QUS variables in powerlifters and controls. The results indicate that the QUS variables BUA and VOS are significantly higher for powerlifters than for controls. PMID:11477028

    2013-01-01

    [Purpose] This study aimed to determine the most appropriate height for shoe heels by measuring the displacement of the COP (center of pressure) and changes in the distribution of foot pressure after walking in flat (0.5 cm), middle-heeled (4 cm), and high-heeled (9 cm) shoes for 1 hour. [Methods] A single-subject design was used, with 15 healthy women wearing shoes with heels of each height in a random order. The foot pressure and displacement of COP before and after walking in an ordinary environment for 1 hour were measured using an FDM-S (zebris Medical GmbH, Germany). [Results] The distribution of foot pressure did not change significantly after walking in middle-heeled (4 cm) shoes but did change significantly after walking in either flat (0.5 cm) or high-heeled (9 cm) shoes. Similarly, the COP was not significantly displaced after walking in middle-heeled (4 cm) shoes but was significantly displaced after walking in either flat (0.5 cm) or high-heeled (9 cm) shoes. [Conclusion] Both flat and high-heeled shoes had adverse effects on the body. Middle-heeled (4 cm) shoes are preferable to both flat (0.5 cm) and high-heeled (9 cm) shoes for the health and comfort of the feet. PMID:24259782

    Studying the impact of high-heeled shoes on kinetic changes and perceived discomfort provides a basis to advance the design and minimize the adverse effects on the human musculoskeletal system. Previous studies demonstrated the effects of inserts on kinetics and perceived comfort in flat or running shoes. No study attempted to investigate the effectiveness of inserts in high heel shoes. The purpose of this study was to determine whether increasing heel height and the use of shoe inserts change foot pressure distribution, impact force, and perceived comfort during walking. Ten healthy females volunteered for the study. The heel heights were 1.0cm (flat), 5.1cm (low), and 7.6cm (high). The heel height effects were examined across five shoe-insert conditions of shoe only; heel cup, arch support, metatarsal pad, and total contact insert (TCI). The results indicated that increasing heel height increases impact force (p<0.01), medial forefoot pressure (p<0.01), and perceived discomfort (p<0.01) during walking. A heel cup insert for high-heeled shoes effectively reduced the heel pressure and impact force (p<0.01), an arch support insert reduced the medial forefoot pressure, and both improved footwear comfort (p<0.01). In particular, a TCI reduced heel pressure by 25% and medial forefoot pressure by 24%, attenuate the impact force by 33.2%, and offered higher perceived comfort when compared to the non-insert condition.

    Objective To evaluate the effect of custom-molded foot orthoses on foot pain and balance in children with symptomatic flexible flat foot 1 month and 3 months after fitting foot orthosis. Method A total of 24 children over 6 years old with flexible flat feet and foot pain for at least 6 months were recruited for this study. Their resting calcaneal stance position and calcaneal pitch angle were measured. Individual custom-molded rigid foot orthoses were prescribed using inverted orthotic technique to control foot overpronation. Pain questionnaire was used to obtain pain sites, degree, and frequency. Balancing ability was determined using computerized posturography. These evaluations were performed prior to custom-molded foot orthoses, 1 month, and 3 months after fitting foot orthoses. Result Of 24 children with symptomatic flexible flat feet recruited for this study, 20 completed the study. Significant (p<0.001) improvements in pain degree and frequency were noted after 1 and 3 months of custom-molded foot orthoses. In addition, significant (p<0.05) improvement in balancing ability was found after 3 months of custom-molded foot orthoses. Conclusion Short-term use of custom-molded foot orthoses significantly improved foot pain and balancing ability in children with symptomatic flexible flat foot. PMID:26798604

    Quantification of plantar tissue behavior of the heel pad is essential in developing computational models for predictive analysis of preventive treatment options such as footwear for patients with diabetes. Simulation based studies in the past have generally adopted heel pad properties from the literature, in return using heel-specific geometry with material properties of a different heel. In exceptional cases, patient-specific material characterization was performed with simplified two-dimensional models, without further evaluation of a heel-specific response under different loading conditions. The aim of this study was to conduct an inverse finite element analysis of the heel in order to calculate heel-specific material properties in situ. Multidimensional experimental data available from a previous cadaver study by Erdemir et al. ("An Elaborate Data Set Characterizing the Mechanical Response of the Foot," ASME J. Biomech. Eng., 131(9), pp. 094502) was used for model development, optimization, and evaluation of material properties. A specimen-specific three-dimensional finite element representation was developed. Heel pad material properties were determined using inverse finite element analysis by fitting the model behavior to the experimental data. Compression dominant loading, applied using a spherical indenter, was used for optimization of the material properties. The optimized material properties were evaluated through simulations representative of a combined loading scenario (compression and anterior-posterior shear) with a spherical indenter and also of a compression dominant loading applied using an elevated platform. Optimized heel pad material coefficients were 0.001084 MPa (μ), 9.780 (α) (with an effective Poisson's ratio (ν) of 0.475), for a first-order nearly incompressible Ogden material model. The model predicted structural response of the heel pad was in good agreement for both the optimization (<1.05% maximum tool force, 0.9% maximum tool displacement) and validation cases (6.5% maximum tool force, 15% maximum tool displacement). The inverse analysis successfully predicted the material properties for the given specimen-specific heel pad using the experimental data for the specimen. The modeling framework and results can be used for accurate predictions of the three-dimensional interaction of the heel pad with its surroundings. PMID:22482682

    Along with Vietnam's development, various hydraulic constructions including concrete gravity dams have been being built. In some of these dams, the fractures occurred at the heel of the dams are even in small and media dams. There are various reasons cause the factures at dam heel but the main reason is the stress states at dam heel are not determined correctly while designing dam. In this paper, several factors affecting stress solution at concrete gravity dam heel such as element mesh size, crack joints of upstream foundation, execution process are investigated by using finite element model of Banve concrete gravity dam. This work is very significant when the more high concrete gravity dams will be constructed in Vietnam year after year.

    Aerodynamics of sails in weakly sheared wind has been studied based on vortex mechanics. Assumptions of small disturbance simplify the basic equations, which show that the effective application of the rudder and coupled heeling and yawing motions give directional stability to sailing craft close to wind. Analysis has also revealed how heel-yaw motion and sheared wind affect the optimization of the thrust with constraints. The result has been compared with the present author's previous work that disregards the heel and the wind shear. While the optimum circulation is independent of the wind shear and the heel-yaw motion, the optimum geometry of sails is little affected by the wind shear. Closed-form solutions are given to represent the optimum design.

    Chronic pressure ulcers (PrUs), ulcers that fail to progress through the expected phases of wound healing in a timely fashion, are not only a concern for the patients afflicted with them, but are also a significant burden for the long-term-care facilities in which patients reside. The heel is the second most common location for PrUs. Morbidity and mortality rates for heel PrUs, particularly in the diabetic population, are alarming. Therefore, a consistently effective, cost-conscious, and user-friendly topical treatment for heel ulcers would be welcomed by patients and clinicians. This article describes a marked and rapid improvement in wound granulation in 3 older adult patients following weekly treatment for 8 weeks of chronic (≥1-year duration) heel ulcers with an easy-to-use, cost-effective, topical, formulated collagen gel.

    Background The use of insoles may enhance postural stability and prevent falls. The aim of this study was to design a new insole and to explore the effectiveness of the insole on the standing balance of the healthy elderly. Methods The study was conducted at a community hospital. Patients older than 65 years at an outpatient clinic without abnormal gait patterns, lower limb deformities, or foot pain were enrolled. The participants were assigned to good- and poor-stability groups on the basis of the stability index (SI), using the Biodex® Balance System. A heel cup with an arch support insole was provided. Participants wore the insole for 8 weeks for a minimum of 4 hours/day. A static balance test for SI was performed at the initial meeting and 8 weeks after the assigned insoles were worn for each participant. Results Five participants (10.0%) of 50 total did not finish the study. There were 25 patients in the good-stability group and 20 in the poor-stability group. The SI, before and after intervention, was significantly different for all 45 participants (3.244±0.688 versus 3.064±0.671; P<0.001). The differences in SI before and after the intervention both in the good-stability group (2.764±0.546 versus 2.592±0.538) and the poor-stability group (3.845±0.188 versus 3.655±0.128) were statistically significant (P<0.001). No statistically significant difference on changes of SI were seen between the two groups. Conclusion The results suggest a heel cup with arch support insole is effective in enhancing the standing balance of the elderly. This may be of benefit in preventing falls. PMID:24600215

    The region in tendons that surrounds bone extremities adapts to compression forces, developing a fibrocartilaginous structure. During maturation, changes occur in the amount and organization of macromolecules of the extracellular matrix of tendons, changing the tissue morphology. To study the effect of maturation on tendons, Pedrês chickens were sacrificed at 1, 5, and 8 months old and had the calcaneal tendon (CT) divided into proximal region, submitted to tension/compression forces (p), and distal region submitted to tension force (d). Morphological analysis of the p region showed the presence of fibrocartilage in all ages. In the central part of the fibrocartilage, near a diminishment of the metachromasy, there was also a development of a probable fat pad that increased with the maturation. The activity of MMP-2 and MMP-9 was higher at 5 and 8 months old, in both regions, compared with 1-month-old animals. In SDS-PAGE analysis, components with electrophoretic migration similar to decorin and fibromodulin increased with maturation, particularly in the d region. The Western blotting confirmed the increased amount of fibromodulin with maturation. In conclusion, our results show that process of maturation leads to the appearance of a probable fat pad in the center of the fibrocartilage of CT, with a reduced amount of glycosaminoglycans and an increased activity of MMPs.

    We present a retrospective study investigating the results of the subjective assessment of displaced intra-articular calcaneal fractures in a selected cohort of 42 patients treated operatively, with a follow-up duration of at least 3 years. The adjusted American Orthopaedic Foot and Ankle Society questionnaire, Foot Function Index, and visual analog scale were used to quantify the subjective evaluations. Our hypothesis was that good subjective results could be predicted and obtained in patients with specific characteristics if anatomic reduction of the fracture was achieved. The results of the study confirmed our hypothesis. A number of specific subgroup analyses were undertaken. The study confirmed that Böhler angle restoration and the quality of reduction of the subtalar joint facet are important prognostic factors related to the outcome. In contrast, gender and Sanders type had less influence at the intermediate-term follow-up results. The main weaknesses of the present study included its retrospective nature, the lack of a control group managed nonoperatively for comparison, and the small sample size. Moreover, the operating surgeon performed the radiographic measurement and categorized the quality of the surgical reconstruction. PMID:22153661

    Sedentary lifestyle contributes to osteoporosis and fragility fracture risks among modern humans, but whether such risks are prevalent in physically active preindustrial societies with lower life expectancies is unclear. Osteoporosis should be readily observable in preindustrial societies if it was regularly experienced over human history. In this study of 142 older adult Tsimane forager-horticulturalists (mean age ± SD, 62.1 ± 8.6 years; range, 50 to 85 years; 51% female) we used calcaneal quantitative ultrasonography (qUS) to assess bone status, document prevalence of adults with reduced bone status, and identify factors (demographic, anthropometric, immunological, kinesthetic) associated with reduced bone status. Men (23%) are as likely as women (25%) to have reduced bone status, although age-related decline in qUS parameters is attenuated for men. Adiposity and fat-free mass positively co-vary with qUS parameters for women but not men. Leukocyte count is inversely associated with qUS parameters controlling for potential confounders; leukocyte count is positively correlated within adults over time, and adults with persistently low counts have higher adjusted qUS parameters (6% to 8%) than adults with a high count. Reduced bone status characteristic of osteoporosis is common among active Tsimane with minimal exposure to osteoporosis risk factors found in industrialized societies, but with energetic constraints and high pathogen burden. © 2015 American Society for Bone and Mineral Research.

    Based on a study of 14 patients younger than 16 years, we found that lumps on the plantar aspect of the anteromedial portion of the heel pad can safely be observed. Many remained small and asymptomatic, some disappeared, and two that required repeated excision biopsy did not subsequently recur. The six patients who were subjected to excision biopsy were found to have plantar fibromatosis. This very precise heel site is a characteristic situation for plantar fibromatosis in childhood.

    The study was taken up to investigate the effects of heel heights on lumbar kinematics and the risk of Low Back Disorder (LBD) in females. Nineteen female university students (24.5 3.36 yrs) volunteered in the study. Lumbar kinematics was measured by using Industrial Lumbar Motion Monitor (iLMM). The volunteers were asked to walk for a distance of 50 meters in 3 different given conditions i.e bare foot (Heel 0), with flat heels (Heel 1) and with high heels (Heel 2). Heights of Heel 1 and Heel 2 were 1.5 0.84 cm and 5.5 1.70 cm respectively. The Lumbar kinematic parameters studied were- Average Twisting Velocity (ATV), Maximum Sagital Flexion (MSF) and Maximum Lateral Velocity (MLV). It was observed that all the above mentioned Lumbar kinematics - ATV, MSF and MLV increases with increase of heel heights, which in turn increases the risk of LBD. As a result of increase in Lumbar kinematic values with increase in heel heights, LBD risk has also increased. Mean and SD of the LBD risk with Heel 0, Heel 1 and Heel 2 were 16.79 6.04%, 19.00 7.38% and 22.11 6.98% respectively. Lower stature with high heels showed higher risk of LBD than the higher stature with high heels. PMID:22317099

  16. Sludge Heel Removal Analysis for Slurry Pumps of Tank 11

    Computational fluid dynamics methods were used to develop and recommend a slurry pump operational strategy for sludge heel removal in Tank 11. Flow patterns calculated by the model were used to evaluate the performance of various combinations of operating pumps and their orientation. The models focused on removal of the sludge heel located at the edge of Tank 11 using the four existing slurry pumps. The models and calculations were based on prototypic tank geometry and expected normal operating conditions as defined by Tank Closure Project (TCP) Engineering. Computational fluid dynamics models of Tank 11 with different operating conditions were developed using the FLUENT(tm) code. The modeling results were used to assess the efficiency of sludge suspension and removal operations in the 75-ft tank. The models employed a three-dimensional approach, a two-equation turbulence model, and an approximate representation of flow obstructions. The calculated local velocity was used as a measure of sludge removal and mixing capability. For the simulations, a series of the modeling calculations was performed with indexed pump orientations until an efficient flow pattern near the potential location of the sludge mound was established for sludge removal. The calculated results demonstrated that the existing slurry pumps running at 1600 rpm could remove the sludge mound from the tank with a 103 in. liquid level, based on a minimum sludge suspension velocity of 2.27 ft/sec. In this case, the only exception is the region within about 2 ft. from the tank wall. Further results showed that the capabilities of sludge removal were affected by the indexed pump orientation, the number of operating pumps, and the pump speed. A recommended operational strategy for an efficient flow pattern was developed to remove the sludge mound assuming that local fluid velocity can be used as a measure of sludge suspension and removal. Sensitivity results showed that for a given pump speed, a higher tank level and a lower pump nozzle elevation would result in better performance in suspending and removing the sludge. The results also showed that the presence of flow obstructions such as valve housing structure were advantageous for certain pump orientations.

  17. Thinking while walking: experienced high-heel walkers flexibly adjust their gait.

    Theories of motor-skill acquisition postulate that attentional demands of motor execution decrease with practice. Hence, motor experts should experience less attentional resource conflict when performing a motor task in their domain of expertise concurrently with a demanding cognitive task. We assessed cognitive and motor performance in high-heel experts and novices who were performing a working memory task while walking in gym shoes or high heels on a treadmill. Surprisingly, neither group showed lower working memory performance when walking than when sitting, irrespective of shoe type. However, high-heel experts adapted walking regularity more flexibly to shoe type and cognitive load than novices, by reducing the variability of time spent in the single-support phase of the gait cycle in high heels when cognitively challenged. We conclude that high-heel expertise is associated with more flexible adjustments of movement patterns. Future research should investigate whether a more demanding walking task (e.g., wearing high heels on uneven surfaces and during gait perturbations) results in expertise-related differences in the simultaneous execution of a cognitive task.

    The aim of the present study was to assess the effect of the use of high-heeled shoes on static balance in young adult women. Fifty-three women between 18 and 30 years of age and accustomed to wearing high-heeled shoes participated in the study. None of the participants had any orthopedic or neurologic alterations. Static balance was assessed using a force plate. Oscillations from the center of pressure in the mediolateral and anteroposterior directions were measured both when barefoot and when wearing high-heeled shoes [7 centimeters (cm) in height and 1cm in diameter] under the conditions of eyes open and eyes closed. Two-way analysis of variance was employed for the statistical analysis, with the level of significance set at 5% (p<.05). The results revealed statistically significant differences between tests when barefoot and when wearing high-heeled shoes as well as with eyes open and eyes closed (p<.01). With the use of high-heeled shoes, there was a significant increase in mediolateral oscillation with eyes closed (p<.01). The present study demonstrates that the use of seven-cm high heels altered static balance in the healthy young women analyzed, increasing the oscillation of the center of pressure, regardless of visual restriction.

    Theories of motor-skill acquisition postulate that attentional demands of motor execution decrease with practice. Hence, motor experts should experience less attentional resource conflict when performing a motor task in their domain of expertise concurrently with a demanding cognitive task. We assessed cognitive and motor performance in high-heel experts and novices who were performing a working memory task while walking in gym shoes or high heels on a treadmill. Surprisingly, neither group showed lower working memory performance when walking than when sitting, irrespective of shoe type. However, high-heel experts adapted walking regularity more flexibly to shoe type and cognitive load than novices, by reducing the variability of time spent in the single-support phase of the gait cycle in high heels when cognitively challenged. We conclude that high-heel expertise is associated with more flexible adjustments of movement patterns. Future research should investigate whether a more demanding walking task (e.g., wearing high heels on uneven surfaces and during gait perturbations) results in expertise-related differences in the simultaneous execution of a cognitive task.

    The networks of blood and lymphatic vessels and of the extracellular matrix and their cellular and structural components, that are collectively termed the tumor microenvironment, are frequently co-opted and shaped by cancer cells to survive, invade, and form distant metastasis. With an enviable capacity to adapt to continually changing environments, cancer represents the epitome of functional chaos, a stark contrast to the hierarchical and organized differentiation processes that dictate the development and life of biological organisms. The consequences of changing landscapes such as hypoxia and acidic extracellular pH in and around tumors create a cascade of changes in multiple pathways and networks that become apparent only several years later as recurrence and metastasis. These molecular and phenotypic changes, several of which are mediated by COX-2, approach the complexities of a Gordian Knot. We review evidence from our studies and from literature suggesting that cyclooxygenase-2 (COX-2) biology presents a nodal point in cancer biology and an Achilles heel of COX-2-dependent tumors.

    The present randomized controlled trial was undertaken to evaluate the effect of tranexamic acid (TXA) on reducing postoperative blood loss in calcaneal fractures. A total of 90 patients with a unilateral closed calcaneal fracture were randomized to the TXA (n = 45) and control (n = 45) groups. The corresponding groups received 15 mg/kg body weight of TXA or placebo (0.9% sodium chloride solution) intravenously before the skin incision was made. Open reduction and internal fixation was performed for all patients and selective bone grafting was performed. The patients were examined 3 months after surgery. The intraoperative and postoperative blood loss, blood test results, and wound complications were compared between the 2 groups. The complications of TXA were also investigated. No statistically significant differences were found in the baseline characteristics between the TXA and control groups. Also, no significant difference was noted in the intraoperative blood loss between the 2 groups. However, in the TXA group, the postoperative blood loss during the first 24 hours was significantly lower than that in the control group (110.0 ± 160.0 mL versus 320.0 ± 360.0 mL; p < .001). The incidence of wound complications was also reduced compared with that in the control group (7.3% versus 23.8%; p = .036). No significant difference was found in the incidence of thromboembolic events or adverse drug reactions between the 2 groups. We concluded that preoperative single-dose TXA can effectively reduce postoperative blood loss and wound complications in patients with calcaneal fractures and that no significant side effects developed compared with the control group.

  4. Foetal pain?

    PubMed

    Derbyshire, Stuart W G

    2010-10-01

    The majority of commentary on foetal pain has looked at the maturation of neural pathways to decide a lower age limit for foetal pain. This approach is sensible because there must be a minimal necessary neural development that makes pain possible. Very broadly, it is generally agreed that the minimal necessary neural pathways for pain are in place by 24 weeks gestation. Arguments remain, however, as to the possibility of foetal pain before or after 24 weeks. Some argue that the foetus can feel pain earlier than 24 weeks because pain can be supported by subcortical structures. Others argue that the foetus cannot feel pain at any stage because it is maintained in a state of sedation in the womb and lacks further neural and conceptual development necessary for pain. Much of this argument rests on the definition of terms such as 'wakefulness' and 'pain'. If a behavioural and neural reaction to a noxious stimulus is considered sufficient for pain, then pain is possible from 24 weeks and probably much earlier. If a conceptual subjectivity is considered necessary for pain, however, then pain is not possible at any gestational age. Regardless of how pain is defined, it is clear that pain for conceptual beings is qualitatively different than pain for non-conceptual beings. It is therefore a mistake to draw an equivalence between foetal pain and pain in the older infant or adult. PMID:20356798

  5. Heel effect adaptive flat field correction of digital x-ray detectors

    2013-08-15

    Purpose: Anode heel effect renders large-scale background nonuniformities in digital radiographs. Conventional offset/gain calibration is performed at mono source-to-image distance (SID), and disregards the SID-dependent characteristic of heel effect. It results in a residual nonuniform background in the corrected radiographs when the SID settings for calibration and correction differ. In this work, the authors develop a robust and efficient computational method for digital x-ray detector gain correction adapted to SID-variant heel effect, without resorting to physical filters, phantoms, complicated heel effect models, or multiple-SID calibration and interpolation.Methods: The authors present the Duo-SID projection correction method. In our approach, conventional offset/gain calibrations are performed only twice, at the minimum and maximum SIDs of the system in typical clinical use. A fast iterative separation algorithm is devised to extract the detector gain and basis heel patterns from the min/max SID calibrations. The resultant detector gain is independent of SID, while the basis heel patterns are parameterized by the min- and max-SID. The heel pattern at any SID is obtained from the min-SID basis heel pattern via projection imaging principles. The system gain desired at a specific acquisition SID is then constructed using the projected heel pattern and detector gain map.Results: The method was evaluated for flat field and anatomical phantom image corrections. It demonstrated promising improvements over interpolation and conventional gain calibration/correction methods, lowering their correction errors by approximately 70% and 80%, respectively. The separation algorithm was able to extract the detector gain and heel patterns with less than 2% error, and the Duo-SID corrected images showed perceptually appealing uniform background across the detector.Conclusions: The Duo-SID correction method has substantially improved on conventional offset/gain corrections for digital x-ray imaging in an SID-variant environment. The technique is relatively simple, and can be easily incorporated into multiple-point gain calibration/correction techniques. It offers a potentially valuable tool for preprocessing digital x-ray images to boost image quality of mammography, chest and cardiac radiography, as well as automated computer aided diagnostic radiology.

    Clothing styles that conceal skin from ultraviolet sun radiation contribute to vitamin D deficiency, especially in veiled female minorities in high latitudes. This is the first research into possible effects of ethnic dress on the os calcis and the first study outside North Africa and the Middle East to investigate whether discernible differences in bone quality exist between veiled and unveiled women. The limited previous research into clothing habits and bone health has been inconclusive. One hundred eight women aged 18--45yr living in the United Kingdom (around 51° north) were analyzed. Forty-three consistently covered arms, hair, and neck when outdoors, whereas 65 consistently had arms, hair, neck, and possibly legs exposed. The quantitative ultrasound scanning (QUS) measurements at the calcaneus were speed of sound (SOS) and broadband ultrasound attenuation (BUA), which were translated into a single clinical value, stiffness index (SI). Dietary intake of vitamin D and calcium was estimated using a validated food frequency questionnaire, and several other risk factors were assessed. There was no significant difference in SI between veiled and unveiled participants (101.30±1.71 vs 99.98±1.86; p=0.721); SOS and BUA were also not significantly different. However, smoking and long-term use of steroid medication were significant predictors of calcaneal bone quality, confirming existing research. Our analysis suggests that clothing style alone does not lead to appreciable differences in the quality of the os calcis in young women in the United Kingdom as assessed by QUS. PMID:22178237

  15. Ultrasound parameters of calcaneal bone density in girls with anorexia nervosa.

    Osteoporosis is common in patients with anorexia nervosa (AN), but ultrasound has so far been scarcely used to detect it We measured calcaneal broadband ultrasound attenuation (BUA) and velocity of sound (VOS) in 26 AN girls (mean age 15.1+/- 1.5 years) using a Cuba Clinical device (McCue Ultrasonics, UK). Basic anthropometric (body weight, height and body mass index--BMI) and clinical data (mean duration of AN, number of absent cycles, weight loss) were collected. All of the girls reported that they did at least one hour's vigorous exercise a day. BUA was significantly lower (p<0.004) and VOS significantly higher (p<0.0001) in comparison with reference data. Body weight and BMI at the time of the measurements were significantly lower than the reference data (p<0.0001). There were no correlations between body weight or height and BUA or VOS, but there was a slight correlation between BUA and BMI (r=0.4, p<0.05) and a slight inverse correlation between VOS, body weight and BMI (r=-0.48 and r=-0.43, p<0.01). VOS slightly correlated with weight loss (r=0.4, p<0.05), significantly with the weekly number of exercise hours (r=0.48, p<0.01). The duration of AN, the number of missed cycles and the percentage of weight loss did not correlate with BUA, and neither the duration of AN nor the number of missed cycles correlated with VOS. The low BUA value could be attributed to poor nutrition, and substantial physical activity may lead to the increase in VOS. In conclusion, girls with AN have low BUA and high VOS values, neither of which correlate with the duration of AN or the number of missed cycles. PMID:11808818

    Background: Soft tissue defects of the lateral malleolus (LM) and Achilles tendon pose difficult reconstructive problems due to the bony prominence and limited local tissue available. The objectives were to study the anatomical landmarks of the lateral calcaneal artery (LCA) and patency of LCA in atherosclerotic patients. Methods: Part I: Thirty-four cadaveric feet were dissected to identify the LCA. The distance between the LCA and the most prominent point of the LM was measured horizontally (LCAa-LM), obliquely (LCAb-LM), and vertically (LCAc-LM). Part II: Thirty-two patients were divided in 2 groups as nonatherosclerotic and atherosclerotic groups. The LCA was assessed by both Doppler ultrasonography and computed tomographic angiography (CTA). Part III: Clinical applications were demonstrated. Results: Part I: Mean distances of LCAa-LM, LCAb-LM, and LCAc-LM were 24.76, 33.68, and 35.03 mm, respectively. The LCA originated 94.12% from the peroneal artery. Part II: Doppler ultrasonography detected the LCA at 90.62% and 87.50% in nonatherosclerotic and atherosclerotic groups, respectively, whereas 100.00% and 93.75%, respectively, were detected by CTA. No statistically significant difference was found in the patency of the LCA between nonatherosclerotic and atherosclerotic patients. Part III: Clinical applications were performed in atherosclerotic patients. Conclusions: The LM is a reliable point to identify the LCA, and the LCA flap can be raised safely in atherosclerotic patients. Preoperative CTA should be performed in severely atherosclerotic patients or cases of major lower extremity vascular injuries. PMID:26495230

  17. Anode heel affect in thoracic radiology: a visual grading analysis

    2006-03-01

    For decades, the antero-posterior (AP) projection of the thoracic spine has represented a substantial challenge. Patient thickness varies substantially along the cranio-caudal axis resulting in images that are too dark for the upper vertebrae and too light, or with excessive quantum mottle, towards the 9th to 12th thoracic vertebra. The anode heel affect is a well known phenomenon, however there is a paucity of reports demonstrating its exploitation in clinical departments for optimising images. The current work, using an adult, tissue-equivalent anthropomorphic phantom, explores if appropriate positioning ofthe anode can improve image quality for thoracic spine radiology. At each of 5 kVps (70, 81, 90, 102, 109) thirty AP thoracic spine images were produced, 15 with the anode end of the tube towards the cranial part of the phantom and 15 with the anode end of the tube facing caudally. Visual grading analysis of the resultant images demonstrated significant improvements in overall image quality and visualisation of specific anatomical features for the cranially facing anode compared with the alternative position, which were most pronounced for the 1st to 4th and 9th to 12th vertebrae. These improvements were evident at 70, 81 and 90 kVp, but not for the higher beam energies. The results demonstrate that correct positioning of the X-ray tube can improve image quality for thoracic radiology at specific tube potentials. Further work is ongoing to investigate whether this easy to implement and cost-free technique can be employed for other examinations.

    The aim of the present study was to compare the outcomes of patients with a displaced calcaneal fracture treated by open reduction and internal fixation (ORIF), percutaneous treatment, or nonoperative methods. A retrospective cohort study was conducted at a level I trauma center of patients with a displaced intra-articular calcaneal fracture treated from January 1, 2002 to December 31, 2011. The patient-reported outcome measures included the Foot Function Index, American Orthopaedic Foot and Ankle Society hindfoot scale, Short Form-36, the EQ-5D from the EuroQol Group, and a 10-point visual analog scale. Clinical data were collected from 169 patients, and questionnaires were obtained from 78 patients (18 nonoperatively, 27 ORIF, and 33 percutaneously). The late intervention rate was significantly greater in the percutaneous group (n = 18; 30%) than in the ORIF group (n = 6; 12%) or the nonoperative group (n = 8; 13%; p = .030). Significantly more disability was reported in the nonoperative group (median Foot Function Index score, 40 points) than in the ORIF group (median, 16 points; p = .010) or in the percutaneous group (median, 21 points; p = .034). In conclusion, the operatively treated patients (ORIF and percutaneous treatment) reported better functional outcome scores (Foot Function Index and American Orthopaedic Foot and Ankle Society hindfoot scale) than did the nonoperatively treated patients.

  19. The influence of a yacht's heeling stability on optimum sail design

    1997-01-01

    This paper presents fundamental results concerning the optimum design of yacht sails and masts. The aerodynamics of a high aspect ratio sail in uniform flow is analysed using lifting line theory to maximise thrust for a given sail area. The novel feature of this work is that thrust is optimised subject to the constraint that the aerodynamic heeling moment generated by the sail is balanced by the righting moment due to hull buoyancy (and the weight of the keel). Initially, the heel angle is therefore unknown, and determined as part of the solution process. Under the assumption of small heel angle, the problem reduces to minimising a quadratic form in the Fourier coefficients for the circulation distribution along the mast, and a simple analytic solution can be derived. It is found that if the mast is too high, the upper section is unused, and as a consequence there is a theoretically ideal mast height for a yacht of given heeling stability. Under the constraints of given sail area and heeling equilibrium it is found that no advantage is to be gained by allowing reverse circulation near the top of the mast. Various implications for yacht performance are discussed.

    Formation of tritium heels in LANA (LaNi{sub 5-x}Al{sub x}) 0.30 (x=0.30) and 0.75 tritides was quantified; size of the heel is dependent on storage and processing conditions. Absorption-desorption cycling of the tritide beds mitigates formation of the tritium heel and can reduce its size. The higher pressure material LANA 0.30 showed slower heel formation than LANA 0.75; this allows more tritium to be removed at the maximum processing temperature. In plant application, LANA 0.30 beds are used as compressors; except during compressor operation, their aging will be very slow. Tritium heel removal by D exchange was demonstrated. Absorption-desorption cycling during an exchange cycle does not improve the exchange efficiency. Residual tritium can be removed to very low levels. For a tritide bed scheduled for removal from the process, a final tritium level can be estimated based on the number of D exchange cycles. 13 refs, 8 figs, 6 tabs.

    Introduction Calcaneal fractures have posed a challenge to orthopaedic surgeon for many years. The major problem is to reconstruct the fracture and improve healing of the fracture and also the surrounding tissues. Anatomic restoration of the three-dimensional anatomy of the calcaneum is the goal of surgical management of calcaneal fractures. Over the years, various techniques have been developed to accomplish this goal. Aim To determine the functional outcome in displaced tongue-type calcaneal fracture treated by percutaneous screw fixation. Materials and Methods A prospective study was conducted from October 2012 and September 2014. A total of 23 patients with intra-articular ‘tongue type’ calcaneal fractures were included in the study. Complete clinical and radiological evaluation was done. The surgical procedure encompassed closed reduction and fixation with two criss-cross 6.5 mm cannulated cancellous across the fracture site under fluoroscopic guidance. Postoperatively, on day three ankle and toe mobilization was begun. Non-weight bearing crutch mobilization was begun on postoperative day three. Reviews were done at 6 weeks, 12 weeks and 24 weeks postoperatively. At 6 weeks partial weight bearing mobilization was started. Full weight bearing was begun at 12 weeks. The patient was finally reviewed at 24 weeks and assessment of ankle function was done as per the Maryland foot scoring system. Radiographs were compared and preoperative and postoperative Gissane’s and Bohler’s angles were also compared. The results were analysed as per descriptive statistics (frequency, percentage). The complications noted were documented. Results Of the 23 patients under the study, three had excellent results with mean score of 90, 17 had good results with mean score of 82.94 and three had fair results with mean score of 74. Only one patient had subtalar arthritis as a complication. No other complications were seen. Conclusion Percutaneous screw fixation of tongue type calcaneal fractures is a very effective surgical technique. PMID:27042539

    The foot is among the sites most often affected in spondyloarthropathies, whose diagnostic criteria include heel pain and sausage-like swelling of the toes. Few studies have systematically analyzed foot manifestations in reactive arthritides. We retrospectively reviewed 143 patients fulfilling Amor's criteria. One hundred five patients (73%) exhibited inflammatory involvement of one (n = 47) or both feet. In 8 cases no other articular sites were affected. Heel pain was reported by 36% of patients (52/143), within the first six months in half the cases. Both heels were painful in 26 patients. Heel pain was plantar in 36 cases, posterior in 7 cases, and bipolar in 4 cases. Roentgenographic calcaneal changes were found in 54 cases overall but in only 31 of the patients with heel pain. Sixteen patients had asymptomatic calcaneitis. Seventeen patients had involvement of the transverse tarsal joint, usually with no other affected joints. Involvement of the subtalar joint was rare (6 cases). Metatarsophalangeal manifestations were found in 44% of patients (64/143) and were symmetrical in 17 cases; 17 patients had changes of the great toe suggestive of gout. Interphalangeal arthritis was seen in 22% (32/143) of cases; in half these cases the first two rays were affected and sausage-like digital swelling was seen in 28 patients (20%). Permanent roentgenological damage was uncommon. PMID:8167638

    Background The reconstruction of ankle and heel defects remains a significant problem for plastic surgeons. The following options exist for reconstructing such defects: local random flaps, reverse flow island flaps, and free flaps. However, each of these methods has certain drawbacks. Peroneal artery perforators have many advantages; in particular, they are predictable and reliable for ankle and heel reconstructions. In this study, we report our clinical experience with peroneal artery perforator-based pedicled flaps in ankle and heel reconstructions. Methods From July 2005 to October 2012, 12 patients underwent the reconstruction of soft tissue defects in the ankle and heel using a peroneal artery perforator-based pedicled flap. These 12 cases were classified according to the anatomical area involved. The cause of the wound, comorbidities, flap size, operative results, and complications were analyzed through retrospective chart review. Results The mean age of the patients was 52.4 years. The size of the flaps ranged from 5×4 to 20×8 cm2. The defects were classified into two groups based on whether they occurred in the Achilles tendon (n=9) or heel pad (n=3). In all 12 patients, complete flap survival was achieved without significant complications; however, two patients experienced minor wound dehiscence. Nevertheless, these wounds healed in response to subsequent debridement and conservative management. No patient had any functional deficits of the lower extremities. Conclusions Peroneal artery perforator-based pedicled flaps were found to be a useful option for the reconstruction of soft tissue defects of the ankle and heel. PMID:26430635

    Selective serotonin reuptake inhibitors (SSRIs) and benzodiazepines are frequently used to treat maternal depression during pregnancy, however the effect of increased serotonin (5HT) and gamma-amino-butyric acid (GABA) agonists in the fetal human brain remains unknown. 5HT and GABA are active during fetal neurologic growth and play early roles in pain modulation, therefore, if prolonged prenatal exposure alters neurodevelopment this may become evident in altered neonatal pain responses. To examine biologic and behavioral effects of prenatal exposure, neonatal responses to acute pain (phenylketonuria heel lance) in infants with prolonged prenatal exposure were examined. Facial action (Neonatal Facial Coding System) and cardiac autonomic reactivity derived from the relationship between respiratory activity and short term variations of heart rate (HRV) were compared between 22 infants with SSRI exposure (SE) [fluoxetine (n = 7), paroxetine (n = 11), sertraline (n = 4)]; 16 infants exposed to SSRIs and clonazepam (SE+) [paroxetine (n = 14), fluoxetine (n = 2)]; and 23 nonexposed infants during baseline, lance, and recovery periods of a heel lance. Length of maternal SSRI use did not vary significantly between exposure groups-[mean (range)] SE:SE+ 183 (31-281):141 (54-282) d (p > 0.05). Infants exposed to SE and SE+ displayed significantly less facial activity to heel lance than control infants. Mean HR increased with lance, but was significantly lower in SE infants during recovery. Using measures of HRV and the transfer relationship between heart rate and respiration, SSRI infants had a greater return of parasympathetic cardiac modulation in the recovery period, whereas a sustained sympathetic response continued in the control group. Prolonged prenatal SSRI exposure appears to be associated with reduced behavioral pain responses and increased parasympathetic cardiac modulation in recovery following an acute neonatal noxious event. Possible 5HT-mediated pain inhibition, pharmacologic factors and the developmental course remain to be studied. PMID:11919328

    High-heeled shoes are associated with instability and a high risk of fall, fracture, and ankle sprain. This study investigated the effects of heel base size (HBS) on walking stability under different walking speeds and slope angles. The trajectory of the center of pressure (COP), maximal peak pressure, pressure time integral, contact area, and perceived stability were analyzed. The results revealed that a small HBS increased the COP deviations, shifting the COP more medially at the beginning of the gait cycle. The slope angle mainly affected the COP in the anteroposterior direction. An increased slope angle shifted the COP posterior and caused greater pressure and a larger contact area in the midfoot and rearfoot regions, which can provide more support. Subjective measures on perceived stability were consistent with objective measures. The results suggested that high-heeled shoes with a small HBS did not provide stable plantar support, particularly on a small slope angle. The changes in the COP and pressure pattern caused by a small HBS might increase joint torque and muscle activity and induce lower limb problems. PMID:25910862

    A feature of healthy gait is a clearly defined heel strike upon initial contact of the foot with the ground. However, a common consequence of ageing is deterioration of the heel first nature of gait towards a shuffling gait (flat foot at contact). Physiotherapy can be effective in correcting this but is costly and labour intensive. Gait rehabilitation could be accelerated with home exercise, guided by a biofeedback device that distinguishes between heel first and shuffling gait. This paper describes an algorithm that distinguishes between heel-to-toe gait and shuffling gait on the basis of angular velocity of the foot, using an inertial measurement unit. Measurements were made of normal and abnormal gait and used to develop an algorithm that distinguishes between good and bad steps. Results demonstrate very good algorithm performance, with a classification accuracy at the accuracy-optimal threshold of 92.7% when compared with physiotherapist labels. The sensitivity and specificity at this threshold are 84.4% and 97.5% respectively. These performance metrics suggest that this algorithm is usable in a biofeedback device. PMID:25570776

    The Minimally Invasive Reduction and Osteosynthesis System(®) (MIROS) is a percutaneous angle stable device for the treatment of fractures. The aim of the present study was to evaluate the clinical and radiographic results of an early minimally invasive osteosynthesis with the MIROS device. A total of 40 consecutive patients were treated for an intra-articular fracture of the calcaneus. We evaluated the clinical and radiographic outcomes after treatment of intra-articular calcaneal fractures with the MIROS hardware. Soft tissue damage was noted. The patients completed the American Orthopaedic Foot and Ankle Society survey at 12 and 24 months and underwent radiologic evaluations. A statistically significant association between the American Orthopaedic Foot and Ankle Society score and type of soft tissue lesion. A Sanders type II, III, and IV fracture was found in 15, 20, and 15 of 50 fractures, respectively. Postoperatively, restoration of the posterior facet was reached in 13 of 15, 18 of 20, and 11 of 15 with a type II, III, and IV fracture, respectively. The American Orthopaedic Foot and Ankle Society scale mean score was 85 at the final follow-up visit. No significant association was found between the score and the preoperative variables (p > .09), although patients with bilateral fractures had a significantly lower score. The MIROS device for early treatment of intra-articular calcaneus fractures resulted in excellent clinic and radiologic results. The standardized technique we have reported, with the elastic wires acting as a girder for the fractured and displace subtalar joint and the collapsed lateral calcaneal wall, has permitted early weightbearing with positive stimuli for the bone healing. The drainage effect of the percutaneous wires likely prevented compartment syndrome when applied within the first hours after the trauma. PMID:25441275

  2. Investigating the Effects of Knee Flexion during the Eccentric Heel-Drop Exercise

    This study aimed to characterise the biomechanics of the widely practiced eccentric heel-drop exercises used in the management of Achilles tendinosis. Specifically, the aim was to quantify changes in lower limb kinematics, muscle lengths and Achilles tendon force, when performing the exercise with a flexed knee instead of an extended knee. A musculoskeletal modelling approach was used to quantify any differences between these versions of the eccentric heel drop exercises used to treat Achilles tendinosis. 19 healthy volunteers provided a group from which optical motion, forceplate and plantar pressure data were recorded while performing both the extended and flexed knee eccentric heel-drop exercises over a wooden step when barefoot or wearing running shoes. This data was used as inputs into a scaled musculoskeletal model of the lower limb. Range of ankle motion was unaffected by knee flexion. However, knee flexion was found to significantly affect lower limb kinematics, inter-segmental loads and triceps muscle lengths. Peak Achilles load was not influenced despite significantly reduced peak ankle plantarflexion moments (p < 0.001). The combination of reduced triceps lengths and greater ankle dorsiflexion, coupled with reduced ankle plantarflexion moments were used to provide a basis for previously unexplained observations regarding the effect of knee flexion on the relative loading of the triceps muscles during the eccentric heel drop exercises. This finding questions the role of the flexed knee heel drop exercise when specifically treating Achilles tendinosis. Key points A more dorsiflexed ankle and a flexing knee are characteristics of performing the flexed knee heel-drop eccentric exercise. Peak ankle plantarflexion moments were reduced with knee flexion, but did not reduce peak Achilles tendon force. Kinematic changes at the knee and ankle affected the triceps muscle length and resulted in a reduction in the amount of Achilles tendon work performed. A version of the heel-drop exercise which reduces the muscle length change will also reduce the amount of tendon stretch, reducing the clinical efficacy of the exercise. PMID:25983597

    Rocker sole shoes are commonly prescribed to diabetic patients with insensate feet. Recent passage of the therapeutic shoe bill has drawn an increased focus to prescription rehabilitative footwear. The purpose of this work is to investigate the dynamics of lower extremity joints (hip, knee and ankle) with the application of a negative heel rocker sole shoe under controlled lab conditions. Forty normal adults volunteered for gait evaluations using controlled baseline and prescription negative heel rocker sole shoes. Three-dimensional motion analysis techniques were used to acquire kinematic and kinetic data using a six-camera Vicon 370 motion system and two AMTI force plates. No significant change in walking speed or stride length was seen with the negative heel rocker shoe, although cadence was increased. The most significant kinematic changes with the application of the negative heel shoe occurred at the ankle in the sagittal plane with increased plantarflexion at terminal stance. Significant hip and knee changes were also noted with increased mid-stance hip extension and knee flexion. The most significant kinetic effects were seen in the transverse plane followed by changes in the sagittal and coronal planes. Changes in power were mostly noted in the sagittal plane. Other statistically significant changes in gait kinematics and kinetics were observed, although the magnitudes and durations were limited and as a result were not considered clinically significant. The study results indicated the negative heel rocker shoe significantly altered proximal joint metrics (hip and knee). The most significant distal joint alterations were seen in sagittal plane ankle kinetics. These kinematic and kinetic changes, along with previously studied effects of pressure relief at the metatarsal heads, should aid medical professionals in prescribing prophylactic footwear.

    Conservative treatments such as in-shoe orthotic heel wedges to treat musculoskeletal injuries are not new. However, weak evidence supporting their use in the management of Achilles tendonitis suggests the mechanism by which these heel wedges works remains poorly understood. It was the aim of this study to test the underlying hypothesis that heel wedges can reduce Achilles tendon load. A musculoskeletal modeling approach was used to quantify changes in lower limb mechanics when walking due to the introduction of 12-mm orthotic heel wedges. Nineteen healthy volunteers walked on an inclinable walkway while optical motion, force plate, and plantar pressure data were recorded. Walking with heel wedges increased ankle dorsiflexion moments and reduced plantar flexion moments; this resulted in increased peak ankle dorsiflexor muscle forces during early stance and reduced tibialis posterior and toe flexor muscle forces during late stance. Heel wedges did not reduce overall Achilles tendon force during any walking condition, but did redistribute load from the medial to lateral triceps surae during inclined walking. These results add to the body of clinical evidence confirming that heel wedges do not reduce Achilles tendon load and our findings provide an explanation as to why this may be the case.

    [Purpose] Revised high-heeled shoes were developed to minimize foot deformities by reducing excessive load on the forefoot during walking or standing in adult females, who frequently wear standard high-heeled shoes. Specifically, this study aimed to investigate the effects of revised high-heeled shoes on foot pressure distribution and center of pressure distance during standing in adult females. [Subjects and Methods] Twelve healthy adult females were recruited to participate in this study. Foot pressures were obtained under 3 conditions: barefoot, in revised high-heeled shoes, and in standard 7-cm high-heeled shoes. Foot pressure was measured using the Tekscan HR mat scan system. One-way repeated analysis of variance was used to compare the foot pressure distribution and center of pressure distance under these 3 conditions. [Results] The center of pressure distance between the two lower limbs and the fore-rear distribution of foot pressure were significantly different for the 3 conditions. [Conclusion] Our findings support the premise that wearing revised high-heeled shoes seems to provide enhanced physiologic standing posture compared to wearing standard high-heeled shoes.

    The aim of our prospective study was to investigate the clinical results and advantages of a minimally invasive sinus tarsi approach with cannulated screw fixation combined with vacuum-assisted closure for the treatment of severe open calcaneal fractures with medial wounds. A total of 31 patients (32 feet) with open calcaneal fractures who were admitted to our hospital from January 2008 to May 2013 were selected for the study and randomly divided into 2 groups: the cannulated screw group (n = 16 patients, 16 feet) and the plate group (n = 15 patients, 16 feet). The Böhler and Gissane angles were compared before and after surgery. The clinical results were evaluated using according to the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale and the rate of infection. The follow-up duration for all patients ranged from 10 to 36 (mean 24) months. No statistically significant differences were found in the radiologic indicators, incidence of early postoperative complications, or American Orthopaedic Foot and Ankle Society ankle-hindfoot scores (p > .05) between the 2 groups. However, a statistically significant difference was seen in the duration of hospitalization (p < .05) between the 2 groups. A minimally invasive sinus tarsi approach with cannulated screw fixation combined with vacuum-assisted closure is an effective method for the treatment of severe open calcaneal fractures with medial wounds. It provides good reduction and requires fewer days of hospitalization. PMID:26372552

    Pain can be defined by several ways, but is usually describes as an unpleasant sensorial or emotional experience related to real or potential tissue damage, or described in terms of such damage. The cancer patient may experience pain related to the cancer itself, its treatment or not related at all with the oncologic disease. It has an extreme importance to the patient, as it is interpreted as a worsening of the prognosis or near death. Therefore it is extremely important a correct approach and treatment of cancer pain. Pain can be treated by pharmacologic, non-pharmacologic means and by more invasive procedures. The options for pharmacologic treatment are various, since nonopioid, opioid analgesics and co-analgesics. The authors present a review of the pharmacological treatment of cancer pain and alert to the importance of the recognition of pain as an illness and the possibility to be relieved. PMID:18183334

  10. Autoantibody pain.

    PubMed

    Goebel, Andreas

    2016-06-01

    As autoantibodies bind to target tissues, Fc-region dependent inflammation can induce pain via mediators exciting nociceptors. But recently another possibility has emerged, where autoantibody binding to nociceptors can directly cause pain, without inflammation. This is thought to occur as a result of Fab-region mediated modification of nerve transduction, transmission, or neuropeptide release. In three conditions, complex regional pain syndrome, anti-voltage gated potassium channel complex autoimmunity, and chronic fatigue syndrome, all associated with no or only little inflammation, initial laboratory-, and clinical trial-results have suggested a potential role for autoantibody-mediated mechanisms. More research assessing the pathogenic roles of autoantibodies in these and other chronic pain conditions is required. The concept of autoantibody-mediated pain offers hope for the development of novel therapies for currently intractable pains. PMID:26883460

  11. Neuropathic Pain

    PubMed Central

    Costigan, Michael; Scholz, Joachim; Woolf, Clifford J.

    2009-01-01

    Neuropathic pain is triggered by lesions to the somatosensory nervous system that alter its structure and function so that pain occurs spontaneously and responses to noxious and innocuous stimuli are pathologically amplified. The pain is an expression of maladaptive plasticity within the nociceptive system, a series of changes that constitute a neural disease state. Multiple alterations distributed widely across the nervous system contribute to complex pain phenotypes. These alterations include ectopic generation of action potentials, facilitation and disinhibition of synaptic transmission, loss of synaptic connectivity and formation of new synaptic circuits, and neuroimmune interactions. Although neural lesions are necessary, they are not sufficient to generate neuropathic pain; genetic polymorphisms, gender, and age all influence the risk of developing persistent pain. Treatment needs to move from merely suppressing symptoms to a disease-modifying strategy aimed at both preventing maladaptive plasticity and reducing intrinsic risk. PMID:19400724

  12. EM-31 RETRIEVAL KNOWLEDGE CENTER MEETING REPORT: MOBILIZE AND DISLODGE TANK WASTE HEELS

    Fellinger, A.

    2010-02-16

    The Retrieval Knowledge Center sponsored a meeting in June 2009 to review challenges and gaps to retrieval of tank waste heels. The facilitated meeting was held at the Savannah River Research Campus with personnel broadly representing tank waste retrieval knowledge at Hanford, Savannah River, Idaho, and Oak Ridge. This document captures the results of this meeting. In summary, it was agreed that the challenges to retrieval of tank waste heels fell into two broad categories: (1) mechanical heel waste retrieval methodologies and equipment and (2) understanding and manipulating the heel waste (physical, radiological, and chemical characteristics) to support retrieval options and subsequent processing. Recent successes and lessons from deployments of the Sand and Salt Mantis vehicles as well as retrieval of C-Area tanks at Hanford were reviewed. Suggestions to address existing retrieval approaches that utilize a limited set of tools and techniques are included in this report. The meeting found that there had been very little effort to improve or integrate the multiple proven or new techniques and tools available into a menu of available methods for rapid insertion into baselines. It is recommended that focused developmental efforts continue in the two areas underway (low-level mixing evaluation and pumping slurries with large solid materials) and that projects to demonstrate new/improved tools be launched to outfit tank farm operators with the needed tools to complete tank heel retrievals effectively and efficiently. This document describes the results of a meeting held on June 3, 2009 at the Savannah River Site in South Carolina to identify technology gaps and potential technology solutions to retrieving high-level waste (HLW) heels from waste tanks within the complex of sites run by the U. S. Department of Energy (DOE). The meeting brought together personnel with extensive tank waste retrieval knowledge from DOE's four major waste sites - Hanford, Savannah River, Idaho, and Oak Ridge. The meeting was arranged by the Retrieval Knowledge Center (RKC), which is a technology development project sponsored by the Office of Technology Innovation & Development - formerly the Office of Engineering and Technology - within the DOE Office of Environmental Management (EM).

    [Purpose] The purpose of this study was to determine the effects of wearing high heels while driving on lower extremity muscle activation. [Subjects] The subjects of this experimental study were 14 healthy women in their 20s who normally wear shoes with high heels. [Methods] The subjects were asked to place their shoes on an accelerator pedal with the heel touching the floor and then asked to press the pedal with as much pressure as possible for 3 seconds before removing their feet from the pedal. A total of 3 measurements were taken for each heel height (flat, 5 cm, 7 cm), and the heel height was randomly selected. [Results] The levels of muscle activity, indicated as the percentage of reference voluntary contraction, for gastrocnemius muscle in the flat, 5 cm, and 7 cm shoes were 180.8±61.8%, 285.4±122.3%, and 366.2±193.7%, respectively, and there were significant differences between groups. Those for the soleus muscle were 477.3±209.2%, 718.8±380.5%, and 882.4±509.9%, and there were significant differences between groups. [Conclusion] To summarize the results of this study, it was found that female drivers require greater lower extremity muscle activation when wearing high heels than when wearing low heels. Furthermore, instability and muscle fatigue of the ankle joint, which results from wearing high heels on a daily basis, could also occur while driving. PMID:25435684

    Study Design Controlled laboratory study. Background Orthotic heel lifts are thought to lower tension in the Achilles tendon, but evidence for this effect is equivocal. Objective To investigate the effect of a 12-mm, in-shoe orthotic heel lift on Achilles tendon loading during shod walking using transmission-mode ultrasonography. Methods The propagation speed of ultrasound, which is governed by the elastic modulus and density of tendon and proportional to the tensile load to which it is exposed, was measured in the right Achilles tendon of 12 recreationally active men during shod treadmill walking at matched speeds (3.4 ± 0.7 km/h), with and without addition of a heel lift. Vertical ground reaction force and spatiotemporal gait parameters were simultaneously recorded. Data were acquired at 100 Hz during 10 seconds of steady-state walking. Statistical comparisons were made using paired t tests (α = .05). Results Ultrasound transmission speed in the Achilles tendon was characterized by 2 maxima (P1, P2) and minima (M1, M2) during walking. Addition of a heel lift to footwear resulted in a 2% increase and 2% decrease in the first vertical ground reaction force peak and the local minimum, respectively (P<.05). Ultrasonic velocity in the Achilles tendon (P1, P2, M2) was significantly lower with the addition of an orthotic heel lift (P<.05). Conclusion Peak ultrasound transmission speed in the Achilles tendon was lower with the addition of a 12-mm orthotic heel lift, indicating that the heel lift reduced tensile load in the Achilles tendon, thereby counteracting the effect of footwear observed in previous studies. These findings support the addition of orthotic heel lifts to footwear in the rehabilitation of Achilles tendon disorders where management aims to lower tension within the tendon.

    Marjolin's ulcer is defined as a malignant, ulcerating neoplasm occurring in cicatricial tissues. The cancer is usually a well-differentiated squamous cell carcinoma. Wide resection is complicated with a recurrence rate of 20% to 50% and a metastasis rate of 54%. Therefore, we chose amputation as the modality of treatment for heel Marjolin's ulcers in Urmia and presented their results in this study.During the last 10 years in Urmia, nineteen cases of heel Marjolin's ulcers has been detected. About 47% were due to childhood burn. Malignancy was mainly squamous cell carcinoma. The mean latent period of malignant transformation was 11 years. All cases were treated with amputation, without any recurrence or metastasis in an average four-year follow-up period.The squamous cell carcinoma of Marjolin's ulcer has the worst prognosis in comparison with other squamous cell carcinomas and it requires an aggressive treatment.

    1996-01-01

    In previous studies on the mechanical properties of the human heel pad (Bennett & Ker, 1990; Aerts et al. 1995) the fat pad and part of the calcaneus was removed from amputated test specimens. The present study tested whether this procedure influences the mechanical behaviour of the sample. Intact amputated feet were therefore mounted on steel rods driven through the calcaneus and placed in a mechanical test situation (pendulum or servohydraulic material tester). The mechanical properties of the pad were determined for a series of experiments in which the pad was gradually freed from the foot in the way done by Bennett & Ker (1990) and Aerts et al. (1995). The results showed no observable differences in the mechanics of the pad by isolating it from the rest of the foot. Thus, in relation to human locomotion, the load-deformation relation of heel pads as described by Aerts et al. (1995) is the most appropriate to date. PMID:8621341

    1990-08-01

    The acceleration in the sagittal plane of the prosthetic tube at heel strike in normal walking was measured in five healthy amputees with their definitive below-knee prosthesis, every subject using six different prosthetic feet, wearing sport shoes as well as leather shoes. The experiments were carried out in the rehabilitation centre "Het Roessingh", Enschede, The Netherlands. Maximum accelerations were extracted from the acceleration-time-signal. Mean acceleration maxima of all subjects were calculated for each foot-shoe combination to eliminate the individual influence of the subjects. In the axial direction the maximal accelerations demonstrate a clear difference among the prosthetic feet and the shoes, while in dorsoventral (tangential) direction the inter-individual variation in the acceleration extremes dominates the difference between the types of footwear. In comparison with non-amputees the magnitude of the maximal axial acceleration at heel strike does not differ significantly. PMID:2235301

    The aim of this study was to investigate how the height and material of in-shoe heel lifts affect plantar pressure and center of pressure (COP) trajectory in the medial-lateral direction during walking. Seventeen healthy young male adults were asked to walk along an 8m walkway while wearing a high-cut flat shoe and 5 different heel lifts. Peak pressure (PP), pressure-time integral (PTI) and contact area (CA) were measured by Pedar insole system for three foot regions: forefoot, midfoot and heel. Range and velocity of medial-lateral (ML) COP during forefoot contact phase (FFCP) and foot flat phase (FFP) were collected using Footscan pressure plate. Forefoot pressure and ML-COP parameters increased as the heel was elevated. Statistically significant attenuation of heel peak plantar pressure was provided by all heel lifts except for the hard lift. Post hoc tests suggest that material had a greater influence on the range and velocity of ML-COP during FFCP than heel height, while during FFP, heel height seemed to affect these parameters more. The findings from this study suggest that thick heel lifts should be used with caution, and that a heel lift made of materials with good support and elastic properties might be more appropriate to improve footwear comfort and medial-lateral motion control.

    According to most published guidelines of cardiopulmonary resuscitation chest compression is performed on the lower half of the sternum by compressing the sternum with the heel of one hand and the other hand on top of the first. In all guidelines and during CPR training great importance is attributed to exact localisation of the so-called compression point. In a laboratory investigation we assessed the force distribution across the heel of the hand and defined the total breadth in contact with the sternum. In order to find out whether there is any difference in the force pattern with the right or the left hand in direct contact with the sternum we determined the resultant maximal force of that part of the heel of the hand exerting the maximal force. A total of 12 anaesthetists performed simulated chest compressions onto a flat surface covered with an integrated force sensor mat. The distance between the most ulnar part and the most radial part of the hand was determined to be 9.2 cm. Similar mean total forces were measured (right hand in contact: 644 N; left hand in contact: 621 N). In all except one anaesthetist the hypothenar part of the heel exerted a significantly higher force compared to the thenar part, independent of whether the right hand or the left hand was in contact. The distance between points of maximal force when the right hand or when the left hand in contact was 2.2 cm corresponding to the breadth of one and a half fingers. To reduce the potential risk of sternal fractures by chest compressions applied too far in a cephalad direction, we recommend use of the right hand in contact if the rescuer kneels at the right side of the patient and vice versa.

  3. Influence of shoes and heel strike on the loading of the hip joint.

    1995-07-01

    The forces and moments acting at the hip joint influence the long-term stability of the fixation of endoprostheses and the course of coxarthrosis. These loads may depend on the kind of footwear and the walking or running style. These factors were investigated in a patient with instrumented hip implants. He wore different sports shoes, normal leather shoes, hiking boots and clogs and walked barefoot with soft, normal and hard heel strikes. The loads were lowest while walking and jogging without shoes. All shoes increased the joint force and the bending moment at the implant slightly but the torsional moment rose by up to 50%. No relation was found between the different type of shoes and the load increase, only shoes with very hard soles were clearly disadvantageous. Soft heels, soles or insoles did not offer advantages. Gait stability seems to play the most important role in increasing the joint loading and should be the criterion for the choice of footwear. Smooth gait patterns with soft heel strikes are the only means to reduce joint loading during slow jogging. PMID:7657680

    The spinal pain, and expecially the low back pain (LBP), represents the second cause for a medical consultation in primary care setting and a leading cause of disability worldwide [1]. LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc collapse and mechanical failure, with no significant modification of external disc shape, with or without endplates changes. IDD is described as a separate clinical entity in respect to disc herniation, segmental instability and degenerative disc desease (DDD). The radicular pain has as most frequent causes a disc herniation and a canal stenosis. Both discogenic and radicular pain also have either a mechanical and an inflammatory genesis. For to be richly innervated, facet joints can be a direct source of pain, while for their degenerative changes cause compression of nerve roots in lateral recesses and in the neural foramina. Degenerative instability is a common and often misdiagnosed cause of axial and radicular pain, being also a frequent indication for surgery. Acute pain tends to extinguish along with its cause, but the setting of complex processes of peripheral and central sensitization may influence its evolution in chronic pain, much more difficult to treat. The clinical assessment of pain source can be a challenge because of the complex anatomy and function of the spine; the advanced imaging methods are often not sufficient for a definitive diagnosis because similar findings could be present in either asymptomatic and symptomatic subjects: a clinical correlation is always mandatory and the therapy cannot rely uniquely upon any imaging abnormalities. Purpose of this review is to address the current concepts on the pathophysiology of discogenic, radicular, facet and dysfunctional pain, focusing on the role of the imaging in the diagnostic setting, to potentially address a correct approach also to minimally invasive interventional techniques. Special attention will be done to the discogenic pain, actually considered as the most frequent cause of chronic low back pain. PMID:25824642

    We defined a spiritual pain as feelings of failure and regret at end-of-life, followed by hopelessness and worthlessness in patient's own life. In Japanese, spiritual pain should be assessed in patient's dignity, psycho-social factor, and prognostic stage, not only in religious context. And patient's spirituality should be supported with providing pain and symptom relief based on human relationships. "Sterbebegleitung" is a German proverb, introduced by Alfons Deeken, and seemed to be a suggestive word for such hope-recovering relationships. PMID:21950035

    The aim of this cross-sectional study was to define the normative data for stiffness index in a large sample of Turkish population and to clarify sex differences as well as age-related changes. A total of 10,435 subjects (aged 18-89 yr) were screened with calcaneal ultrasound and were requested to complete a detailed questionnaire listing all important risk factors, diseases, and treatments affecting bone metabolism. To be included in the study, subjects had to be free of any disease and any medical treatment known to affect bone metabolism. A total of 8,156 subjects (1,389 males and 6,767 females) were included in the study. Normative data was expressed using two statistical models including mean and 95th percentile, and regression analysis. The mean value of stiffness index in females peaked in the third decade, whereas in males it peaked in the age group of 18-29 yr. The stiffness index of females decreased by 24.26%. The total age-related decrease was 17.8% for stiffness index in the males. Stiffness index in males was a function of age (negatively) and body mass index (positively). Stiffness index in females was a function of age (negatively) and weight (positively). The results of this study could be useful as a guide for comparing the data of individual studies and may serve as reference normative data for the Turkish population. PMID:16785084

    The purpose of this paper is to evaluate the prospects of using bulk waste characteristics to determine the most appropriate heel retrieval technology. If the properties of hard to remove heels can be determined before bulk retrieval, then a heel retrieval technology can be selected before bulk retrieval is complete. This would save substantially on sampling costs and would allow the deployment of the heel retrieval technology immediately after bulk retrieval. The latter would also accelerate the heel removal schedule. A number of C-farm retrievals have been fully or partially completed at the time of this writing. Thus, there is already substantial information on the success of different technologies and the composition of the heels. There is also substantial information on the waste types in each tank based on historical records. Therefore, this study will correlate the performance of technologies used so far and compare them to the known waste types in the tanks. This will be used to estimate the performance of future C Farm heel retrievals. An initial decision tree is developed and employed on tanks C-101, C-102, and C 111. An assumption of this study is that no additional characterization information would be available, before or after retrieval. Note that collecting additional information would substantially increase the probability of success. Deploying some in-situ testing technologies, such as a water lance or an in-situ Raman probe, might substantially increase the probability of successfully selecting the process conditions without having to take samples from the tanks for laboratory analysis.

  19. Relationship between hamstring activation rate and heel contact velocity: Factors influencing age-related slip-induced falls

    2010-01-01

    The purpose of this research was to determine whether a decreased hamstring activation rate among the elderly is responsible for a higher horizontal heel contact velocity and increased likelihood of slip-induced falls compared to their younger counterparts. Twenty-eight subjects from two age groups (14 young and 14 old) walked across a linear walking track with embedded force platforms while wearing a fall arresting harness attached to an overhead arresting rig for safety. In order to obtain realistic unexpected slip-induced fall data, a soapy vinyl floor surface was hidden from the subjects and unexpectedly introduced. Synchronized kinematics, kinetic and electromyography (EMG) analyses during the heel contact phase of the gait cycle while walking over slippery and non-slippery floor surfaces were examined in the study. Normalized EMG data were examined in terms of hamstring activation rate and evaluated with heel contact velocity and friction demand characteristic (as measured by peak required coefficient of friction (RCOF)) on the dry vinyl floor surface. Furthermore, slip parameters (i.e. slip distances and slipping velocity) were assessed on the soapy vinyl floor surface. The results indicated that younger adults’ hamstring activation rate was higher than older adults, whereas younger adults’ heel contact velocity was not different from older adults. These results suggested that heel contact velocity in younger adults was sufficiently reduced before the heel contact phase of the gait cycle. This could be due to the outcome of higher hamstring activation rate in younger adults in comparison to older adults. However, lower friction demand (peak RCOF), shorter slip distances, slower peak sliding heel velocity and more falls among older adults suggested that the slip initiation characteristics were not the only factors contributing to slip-induced falls among the elderly.

    NEW OPIOID ANALGESICS: Progress in pain reliet has recently been achieved with the introduction of new opioid analgesics such as tramadol and the pediatric preparation of codeine phosphate as well as powerful long-release opioids which can be administered per os, or percutaneously for transdermal fentanyl. CO-ANALGESICS: Other drugs, mainly antidepressants and anti-convulsants, can be usefully combined with analgesics. New serotonin uptake inhibitors and anticonvulsants (gabapentin and lamotrigin) have the advantage of better tolerance. None of these drugs has marketing approval in France for their pain relieving effects. The same is true for clonidine and neostigmine which, after spinal infusion, potentialize opioids and for ketamine which can relieve neuropathy pain by dissociative anesthesia. NEW ANTI-MIGRAINE DRUGS: New drugs have been developed for specific types of pain such as migraine. The new "triptans" are tolerated better than sumatriptan and is reimbursed by the national social security. REFRACTORY NEUROPATHY PAIN: Indications for electrical stimulation techniques conducted in a neurosurgery unit have been identified. Stimulators may be implanted in spinal or supra-spinal localizations. REGULATORY ASPECTS: New legislation has reorganized health care for pain relief in France. The new texts take into consideration personnel training, the health care network and progress in therapeutics. PMID:9893699

    How perception of pain emerges from neural activity is largely unknown. Identifying a neural 'pain signature' and deriving a way to predict perceived pain from brain activity would have enormous basic and clinical implications. Researchers are increasingly turning to functional brain imaging, often applying machine-learning algorithms to infer that pain perception occurred. Yet, such sophisticated analyses are fraught with interpretive difficulties. Here, we highlight some common and troublesome problems in the literature, and suggest methods to ensure researchers draw accurate conclusions from their results. Since functional brain imaging is increasingly finding practical applications with real-world consequences, it is critical to interpret brain scans accurately, because decisions based on neural data will only be as good as the science behind them.

    To study the expression level of a panel of pro/anti-apoptotic factors and inflammation-related receptors in chondral fragments from patients undergoing surgical treatment for intra-articular calcaneal fractures, cartilage fragments were retrieved from calcaneal fractures of 20 patients subjected to surgical treatment. Primary cultures were performed using chondral fragments from fractured and control patients. Chondrocyte cultures from each patient of the fractured and control groups were subjected to immunofluorescence staining and quantitatively analyzed under confocal microscopy. Proteins extracted from the cultured chondrocytes taken from the fractured and control groups were processed for Western blot experiments and densitometric analysis. The percentage of apoptotic cells was determined using the cleaved PARP-1 antibody. The proportion of labelled cells was 35% for fractured specimens, compared with 7% for control samples. Quantification of caspase-3 active and Bcl-2 proteins in chondrocyte cultures showed a significant increase of the apoptotic process in fractured specimens compared with control ones. Fractured chondrocytes were positively stained for ChemR23 with statistically significant differences with respect to control samples. Densitometric evaluation of the immunoreactive bands confirmed these observations. Human articular chondrocytes obtained from patients with intra-articular calcaneal fractures express higher levels of pivotal pro-apoptotic factors, and of the chemo-attractive receptor ChemR23, compared with control cultures. On the basis of these observations, the authors hypothesize that consistent prolonged chondrocyte death, associated with the persistence of high levels of pro-inflammatory factors, could enhance the deterioration of cartilage tissue with consequent development of post-traumatic arthritis following intra-articular bone fracture.

    The damping mechanisms that are operational in the heel pad during the impact phase of locomotion have the important function to protect the musculo-skeletal system from injuries. How this is achieved is still not fully understood, as is for instance illustrated by the 'heel pad paradox', the observation that in vivo and in vitro experiments yielded widely different results. This paradox could so far only partially be explained. In the light of this paradox, and a previous study by our group, we conjectured that the venous plexus might contribute as a hydraulic shock absorber to the damping properties of the heel pad. To investigate this hypothesis in vivo, heel pads of 11 volunteers were subjected to pendulum impact tests, using velocities of 0.2, 0.4, and 0.6 m/s, and three physiologically different, consecutive conditions: (i) a relatively empty venous plexus, (ii) a congested venous plexus, and (iii) a decongested venous plexus. At congestion, the maximum impact force decreased slightly but significantly by 2.6% at 0.2 m/s and 1.8% at 0.4 m/s. This effect was no longer found at 0.6 m/s. Although these effects are rather small, they confirm the fundamental hypothesis that the venous plexus contributes to the damping properties of the heel pad during walking. It is likely that some underestimation of the effect has occurred. PMID:16214490

  4. Bohler’s angle’s role in assessing the injury severity and functional outcome of internal fixation for displaced intra-articular calcaneal fractures: a retrospective study

    Background Controversy exits over the role of Böhler’s angle in assessing the injury severity of displaced intra-articular calcaneal fractures and predicting the functional outcome following internal fixation. This study aims to investigate whether a correlation exists between Böhler’s angle and the injury severity of displaced calcaneal fractures, and between surgical improvement of Böhler’s angle and functional outcome. Methods Patients treated operatively for unilateral closed displaced intra-articular calcaneal fractures from January 1, 2004 to March 31, 2008 were identified. The Böhler’s angles of both calcaneus were measured, and the measurement of the uninjured foot was used as its normal control. The difference in the value of Böhler’s angle measured preoperatively or postoperatively between the angle of the injured foot and that of the contralateral calcaneus were calculated, respectively. The change in Böhler’s angle by ratio was calculated by dividing the difference value of Böhler’s angle between bilateral calcaneus by its normal control. The injury severity was assessed according to Sanders classification. The functional outcomes were assessed using American Orthopaedic Foot & Ankle Society hindfoot scores. Results 274 patients were included into the study with a mean follow-up duration of 71 months. According to Sanders classification, the fracture pattern included 105 type II, 121 type III and 48 type IV fractures. According to American Orthopaedic Foot & Ankle Society hindfoot scoring system, the excellent, good, fair and poor results were achieved in 104, 132, 27, and 11 patients, respectively. The preoperative Böhler’s angle, difference value of Böhler’s angle between bilateral calcaneus, and change in Böhler’s angle by ratio each has a significant correlation with Sanders classification (rs=−0.178, P=0.003; rs=−0.174, P=0.004; rs=−0.172, P=0.005, respectively), however, is not correlated with functional outcome individually. The three postoperative measurements were all found to have a significant correlation with American Orthopaedic Foot & Ankle Society hindfoot scores (rs=0.223, P<0.001; rs=0.224, P<0.001; rs=0.220, P<0.001, respectively). However, these correlations were all weak to low. Conclusions There was a significant correlation between preoperative Böhler’s angle and the injury severity of displaced intra-articular calcaneal fractures, but only postoperative Böhler’s angle parameters were found to have a significant correlation with the functional recovery.

    Background: low bone mineral density measured by dual-energy x-ray absorptiometry is associated with increased mortality. The relationship between other skeletal phenotypes and mortality is unclear. The aim of this study was to determine the relationship between quantitative heel ultrasound parameters and mortality in a cohort of European men. Methods: men aged 40–79 years were recruited for participation in a prospective study of male ageing: the European Male Ageing Study (EMAS). At baseline, subjects attended for quantitative ultrasound (QUS) of the heel (Hologic—SAHARA) and completed questionnaires on lifestyle factors and co-morbidities. Height and weight were measured. After a median of 4.3 years, subjects were invited to attend a follow-up assessment, and reasons for non-participation, including death, were recorded. The relationship between QUS parameters (broadband ultrasound attenuation [BUA] and speed of sound [SOS]) and mortality was assessed using Cox proportional hazards model. Results: from a total of 3,244 men (mean age 59.8, standard deviation [SD] 10.8 years), 185 (5.7%) died during the follow-up period. After adjusting for age, centre, body mass index, physical activity, current smoking, number of co-morbidities and general health, each SD decrease in BUA was associated with a 20% higher risk of mortality (hazard ratio [HR] per SD = 1.2; 95% confidence interval [CI] = 1.0–1.4). Compared with those in higher quintiles (2nd–5th), those in the lowest quintile of BUA and SOS had a greater mortality risk (BUA: HR = 1.6; 95% CI = 1.1–2.3 and SOS: HR = 1.6; 95% CI = 1.2–2.2). Conclusion: lower heel ultrasound parameters are associated with increased mortality in European men. PMID:26162912

  7. SLUDGE HEEL REMOVAL BY ALUMINUM DISSOLUTION AT SAVANNAH RIVER SITE 12390

    2012-01-12

    High Level Waste (HLW) at the Savannah River Site (SRS) is currently stored in aging underground storage tanks. This waste is a complex mixture of insoluble solids, referred to as sludge, and soluble salts. Continued long-term storage of these radioactive wastes poses an environmental risk. Operations are underway to remove and disposition the waste, clean the tanks and fill with grout for permanent closure. Heel removal is the intermediate phase of the waste retrieval and tank cleaning process at SRS, which is intended to reduce the volume of waste prior to treatment with oxalic acid. The goal of heel removal is to reduce the residual amount of radioactive sludge wastes to less than 37,900 liters (10,000 gallons) of wet solids. Reducing the quantity of residual waste solids in the tank prior to acid cleaning reduces the amount of acid required and reduces the amount of excess acid that could impact ongoing waste management processes. Mechanical heel removal campaigns in Tank 12 have relied solely on the use of mixing pumps that have not been effective at reducing the volume of remaining solids. The remaining waste in Tank 12 is known to have a high aluminum concentration. Aluminum dissolution by caustic leaching was identified as a treatment step to reduce the volume of remaining solids and prepare the tank for acid cleaning. Dissolution was performed in Tank 12 over a two month period in July and August, 2011. Sample results indicated that 16,440 kg of aluminum oxide (boehmite) had been dissolved representing 60% of the starting inventory. The evolution resulted in reducing the sludge solids volume by 22,300 liters (5900 gallons), preparing the tank for chemical cleaning with oxalic acid.

    Despite published guidelines and educational programs on the assessment and treatment of cancer-related pain, in any stage of oncological disease, unrelieved pain continues to be a substantial worldwide public health concern either in patients with solid and haematological malignancies. The proper and regular self-reporting assessment of pain is the first step for an effective and individualized treatment. Opioids are the mainstay of analgesic therapy and can be associated with non-opioids drugs such as paracetamol or non-steroidal anti-inflammatory drugs and to adjuvant drugs (for neuropathic pain and symptom control). The role and the utility of weak opioids (i.e. codeine, dihydrocodeine, tramadol) are a controversy point. Morphine has been placed by World Health Organization on its Essential Drug List. In the comparative study with other strong opioids (hydromorphone, oxycodone), there is no evidence to show superiority or inferiority with morphine as the first choice opioid. Oral methadone is a useful and safe alternative to morphine. Methadone presents the potential to control pain difficult to manage with other opioids. although the oral route of opioid administration is considered the one of choice, intravenous, subcutaneous, rectal, transdermal, sublingual, intranasal, and spinal routes must be used in particular situation. Transdermal opioids such as fentanyl and buprenorphine are best reserved for patients whose opioid requirements are stable. Switching from one opioid to another can improve analgesia and tolerability. PMID:22987980

    Chronic visceral pain is an unresolved neurobiological, medical and socioeconomic challenge. Up to 20% of the adult population suffer from chronic visceral pain and abdominal complaints constitute a prevalent symptom also in children and adolescents. Existing treatment approaches are often unsuccessful and patients typically suffer from multiple somatic and psychological symptoms. This complex situation requires integrative treatment approaches. This review summarizes current basic and clinical research on acute and chronic visceral pain with a focus on research groups in Germany. Despite significant clinical and scientific advances, a number of questions remain open calling for more funding to support research to elucidate the complex pathophysiology of chronic visceral pain and to develop and test new treatment approaches. Research support should focus on interdisciplinary concepts and methodology using expertise from multiple disciplines. The field would also benefit from a broader integration of visceral pain into teaching curricula in medicine and psychology and should aim to motivate young clinicians and scientists to strive for a career within this important and highly fascinating area.

    The purpose of this report is to describe a case in which a heel ulcer with atypical features, i.e., large size and rapid progression, led to diagnosis of squamous cell carcinoma. Patient management was based on specialist advice obtained by "tele-dermatology" based on pictures and comments transmitted over the Internet. However, due to the risk of spreading and impossibility of providing other medical treatment (radiotherapy-chemotherapy), the lower limb was amputated at the top of the thigh. PMID:21585103

    Eight samples of heel solids from tank 241-C-109 were delivered to the 222-S Laboratory for characterization and dissolution testing. After being drained thoroughly, one-half to two-thirds of the solids were off-white to tan solids that, visually, were fairly evenly graded in size from coarse silt (30-60 μm) to medium pebbles (8-16 mm). The remaining solids were mostly strongly cemented aggregates ranging from coarse pebbles (16-32 mm) to fine cobbles (6-15 cm) in size. Solid phase characterization and chemical analysis indicated that the air-dry heel solids contained ≈58 wt% gibbsite [Al(OH){sub 3}] and ≈37 wt% natrophosphate [Na{sub 7}F(PO{sub 4}){sub 2}�19H{sub 2}O]. The strongly cemented aggregates were mostly fine-grained gibbsite cemented with additional gibbsite. Dissolution testing was performed on two test samples. One set of tests was performed on large pieces of aggregate solids removed from the heel solids samples. The other set of dissolution tests was performed on a composite sample prepared from well-drained, air-dry heel solids that were crushed to pass a �-in. sieve. The bulk density of the composite sample was 2.04 g/mL. The dissolution tests included water dissolution followed by caustic dissolution testing. In each step of the three-step water dissolution tests, a volume of water approximately equal to 3 times the initial volume of the test solids was added. In each step, the test samples were gently but thoroughly mixed for approximately 2 days at an average ambient temperature of 25 �C. The caustic dissolution tests began with the addition of sufficient 49.6 wt% NaOH to the water dissolution residues to provide ≈3.1 moles of OH for each mole of Al estimated to have been present in the starting composite sample and ≈2.6 moles of OH for each mole of Al potentially present in the starting aggregate sample. Metathesis of gibbsite to sodium aluminate was then allowed to proceed over 10 days of gentle mixing of the test samples at temperatures ranging from 26-30 �C. The metathesized sodium aluminate was then dissolved by addition of volumes of water approximately equal to 1.3 times the volumes of caustic added to the test slurries. Aluminate dissolution was allowed to proceed for 2 days at ambient temperatures of ≈29 �C. Overall, the sequential water and caustic dissolution tests dissolved and removed 80.0 wt% of the tank 241-C-109 crushed heel solids composite test sample. The 20 wt% of solids remaining after the dissolution tests were 85-88 wt% gibbsite. If the density of the residual solids was approximately equal to that of gibbsite, they represented ≈17 vol% of the initial crushed solids composite test sample. In the water dissolution tests, addition of a volume of water ≈6.9 times the initial volume of the crushed solids composite was sufficient to dissolve and recover essentially all of the natrophosphate present. The ratio of the weight of water required to dissolve the natrophosphate solids to the estimated weight of natrophosphate present was 8.51. The Environmental Simulation Program (OLI Systems, Inc., Morris Plains, New Jersey) predicts that an 8.36 w/w ratio would be required to dissolve the estimated weight of natrophosphate present in the absence of other components of the heel solids. Only minor amounts of Al-bearing solids were removed from the composite solids in the water dissolution tests. The caustic metathesis/aluminate dissolution test sequence, executed at temperatures ranging from 27-30 �C, dissolved and recovered ≈69 wt% of the gibbsite estimated to have been present in the initial crushed heel solids composite. This level of gibbsite recovery is consistent with that measured in previous scoping tests on the dissolution of gibbsite in strong caustic solutions. Overall, the sequential water and caustic dissolution tests dissolved and removed 80.3 wt% of the tank 241-C-109 aggregate solids test sample. The residual solids were 92-95 wt% gibbsite. Only a minor portion (≈4.5 wt%) of the aggregate solids was dissolved and recovered in the water dissolution test. Other than some smoothing caused by continuous mixing, the aggregates were essentially unaffected by the water dissolution tests. During the caustic metathesis/aluminate dissolution test sequence, ≈81 wt% of the gibbsite estimated to have been present in the aggregate solids was dissolved and recovered. The pieces of aggregate were significantly reduced in size but persisted as distinct pieces of solids. The increased level of gibbsite recovery, as compared to that for the crushed heel solids composite, suggests that the way the gibbsite solids and caustic solution are mixed is a key determinant of the overall efficiency of gibbsite dissolution and recovery. The liquids recovered after the caustic dissolution tests on the crushed solids composite and the aggregate solids were observed for 170 days. No precipitation of gibbsite was observed. The distribution of particle sizes in the residual solids recovered following the dissolution tests on the crushed heel solids composite was characterized. Wet sieving indicated that 21.4 wt% of the residual solids were >710 μm in size, and laser light scattering indicated that the median equivalent spherical diameter in the <710-μm solids was 35 μm. The settling behavior of the residual solids following the large-scale dissolution tests was also studied. When dispersed at a concentration of ≈1 vol% in water, ≈24 wt% of the residual solids settled at a rate >0.43 in./s; ≈68 wt% settled at rates between 0.02 and 0.43 in./s; and ≈7 wt% settled slower than 0.02 in./s.

  12. Results of Characterization and Retrieval Testing on Tank 241-C-110 Heel Solids

    Nine samples of heel solids from tank 241-C-110 were delivered to the 222-S Laboratory for characterization and dissolution testing. After being drained thoroughly, the sample solids were primarily white to light-brown with minor dark-colored inclusions. The maximum dimension of the majority of the solids was <2 mm; however, numerous pieces of aggregate, microcrystalline, and crystalline solids with maximum dimensions ranging from 5-70 mm were observed. In general, the larger pieces of aggregate solids were strongly cemented. Natrophosphate [Na{sub 7}F(PO{sub 4}){sub 2}�19H{sub 2}O] was the dominant solid phase identified in the heel solids. Results of chemical analyses suggested that 85-87 wt% of the heel solids were the fluoridephosphate double salt. The average bulk density measured for the heel solids was 1.689 g/mL; the reference density of natrophosphate is 1.71 g/mL. Dissolution tests on composite samples indicate that 94 to 97 wt% of the tank 241-C-110 heel solids can be retrieved by dissolution in water. Dissolution and recovery of the soluble components in 1 kg (0.59 L) of the heel solids required the addition of ≈9.5 kg (9.5 L) of water at 15 �C and ≈4.4 kg (4.45 L) of water at 45 �C. Calculations performed using the Environmental Simulation Program indicate that dissolution of the ≈0.86 kg of natrophosphate in each kilogram of the tank 241-C-110 heel solids would require ≈9.45 kg of water at 15 �C and ≈4.25 kg of water at 45 �C. The slightly larger quantities of water determined to be required to retrieve the soluble components in 1 kg of the heel solids are consistent with that required for the dissolution of solids composed mainly of natrophosphate with a major portion of the balance consisting of highly soluble sodium salts. At least 98% of the structural water, soluble phosphate, sodium, fluoride, nitrate, carbonate, nitrite, sulfate, oxalate, and chloride in the test composites was dissolved and recovered in the dissolution tests. Most of the {sup 99}Tc and {sup 137}Cs present in the initial heel solids composites was removed in the water dissolution tests. The estimated activities/weights of {sup 129}I, {sup 234}U, {sup 235}U, {sup 236}U, and {sup 238}U in the dry residual solids were <25% of the weights/activities in the initial composite solids. Gibbsite and nordstrandite [both Al(OH){sub 3}] were the major solid phases identified in the solids remaining after completion of the dissolution tests. Chemical analysis indicated that the residual solids may have contained up to 62 wt% Al(OH){sub 3}. Significant quantities of unidentified phosphate-, iron-, bismuth-, silicon-, and strontium- bearing species were also present in the residual solids. The reference density of gibbsite (and nordstrandite) is 2.42 g/mL. The measured density of the residual solids, 2.65 g/mL, would be a reasonable value for solids containing gibbsite as the major component with minor quantities of other, higher density solids. Sieve analysis indicated that 22.2 wt% of the residual solids were discrete particles >710 μm in size, and 77.8 wt% were particulates <710 μm in size. Light-scattering measurements suggested that nearly all of the <710-μm particulates with diameters >12 μm were weakly bound aggregates of particles with diameters <2 μm. The <710-μm residual solids settled very slowly when dispersed in reagent water. The physical appearance of a suspension containing ≈0.4 vol% of the solids in pure water changed very little over a period of 46.5 hours. It should be noted that the distribution of particle sizes in the residual solids and the observed settling behavior were both strongly influenced by the procedures followed in the dissolution tests.

    The calcaneus is the most common tarsal affected by unicameral bone cysts (UBCs); however, the treatment of calcaneal UBCs remains controversial. The purpose of the present systematic review was to evaluate the treatment modalities for calcaneal UBCs. A systematic review was performed using clinical studies of calcaneal UBCs with a minimum of 1 year of follow-up and level I to IV evidence. Ten studies with 171 patients (181 cysts) were selected. Heel pain and radiographic cyst consolidation were the primary outcomes. A series of Z tests were used to compare the outcomes in the nonoperative and operative groups, cannulated screw and bone augmentation groups, and autografting and allografting groups. All patients treated with open curettage and bone augmentation had significant improvements in heel pain (p < .001). Only 1.1% ± 1.0% of the cysts treated conservatively had healed on radiographs compared with 93.0% ± 13.0% of the cysts after surgery (p < .001). A greater percentage of patients treated with bone augmentation had preoperative heel pain and resolution of that pain than did patients treated with cannulated screws (p < .001). Autografting had a significantly greater percentage of radiographic cyst consolidation than did allografting (97.4% ± 11.1% versus 85.1% ± 15.8%, p < .001, Z = 3.5). Objective outcomes data on calcaneal UBCs are relatively sparse. The results of the present review suggest that open curettage with autograft bone augmentation is the most effective procedure. We would encourage future comparative clinical studies to elucidate differences in UBC treatment modalities. PMID:25638776

  14. The X-ray attenuation characteristics and density of human calcaneal marrow do not change significantly during adulthood

    Changes in the material characteristics of bone marrow with aging can be a significant source of error in measurements of bone density when using X-ray and ultrasound imaging modalities. In the context of computed tomography, dual-energy computed techniques have been used to correct for changes in marrow composition. However, dual-energy quantitative computed tomography (DE-QCT) protocols, while increasing the accuracy of the measurement, reduce the precision and increase the radiation dose to the patient in comparison to single-energy quantitative computed tomography (SE-QCT) protocols. If the attenuation properties of the marrow for a particular bone can be shown to be relatively constant with age, it should be possible to use single-energy techniques without experiencing errors caused by unknown marrow composition. Marrow was extracted by centrifugation from 10 mm thick frontal sections of 34 adult cadaver calcanei (28 males, 6 females, ages 17-65 years). The density and energy-dependent linear X-ray attenuation coefficient of each marrow sample were determined. For purposes of comparing our results, we then computed an effective CT number at two GE CT/i scan voltages (80 and 120 kVp) for each specimen. The coefficients of variation for the density, CT number at 80 kVp and CT number at 120 kVp were each less than 1%, and the parameters did not change significantly with age (p > 0.2, r2 < 0.02, power > 0.8 where the minimum acceptable r2 = 0.216). We could demonstrate no significant gender-associated differences in these relationships. These data suggest that calcaneal bone marrow X-ray attenuation properties and marrow density are essentially constant from the third through sixth decades of life.

    Squamous cell carcinoma (SCC) is the second most common skin cancer; however, it is relatively rare on the foot. Wide excision of SCC is the recommended surgical treatment. The extent of the excision may involve resection of muscles and bone in cases of deep lesions. The functional and anatomic properties and lack of sufficient locally available tissues make the reconstruction of post-oncosurgical defects of the foot a challenging process. Heel reconstruction poses the biggest challenge due to the unique weight-bearing requirements. We present a case of a Marjolin's ulcer on the heel in a 62-year-old woman complicating a chronic non-healing wound. The heel defect was reconstructed with a free latissimus dorsi myocutaneous flap with delayed secondary closure. The outcome was successful both functionally and cosmetically. No further procedures were needed. PMID:27161144

  16. In-shoe plantar pressure measurements for patients with knee osteoarthritis: Reliability and effects of lateral heel wedges.

    Although plantar pressure measurement systems are being used increasingly during gait analyses to investigate foot orthotics, there is limited information describing test-retest reliability of such measurements. Objectives of this study were to (1) examine the test-retest reliability of lateral heel pressure (LHP) and centre of pressure (COP) during walking with and without lateral heel wedges, and (2) evaluate the effects of 4° and 8° lateral heel wedges on the magnitude of LHP, the pathway of the COP and the peak external knee adduction moment (KAM) in subjects with and without knee osteoarthritis (OA). Twenty-six subjects, 12 patients with knee OA and 14 healthy subjects, were evaluated during three lateral heel wedge conditions (control, 4° and 8°) with standardized footwear. Three-dimensional analyses of gait with optical motion capture, floor-mounted force plate and in-shoe plantar pressure were completed on two occasions. Intraclass correlation coefficients (ICC(2, 1)) for LHP were excellent (0.79-0.83) while ICCs for COP in the medial-lateral and anterior-posterior directions were more variable (0.66-0.86). Reliability was slightly diminished when using heel wedges. Standard errors of measurement suggested considerable day-to-day variability in an individual's measures. Lateral heel wedges significantly (p<0.001) increased LHP, shifted COP anteriorly and laterally, and decreased the KAM. No significant differences were observed between subjects with and without OA. Although the day-to-day variability appears too large to confidently evaluate changes in individual patients, and decreases in reliability with increases in wedge size indicate caution, these results suggest in-shoe measurement of LHP and COP are appropriate for use in studies evaluating biomechanical effects of foot orthoses for knee OA.

    2008-01-16

    Chemical Sludge Removal (CSR) is the final waste removal activity planned for some of the oldest nuclear waste tanks located at the Savannah River Site (SRS) in Aiken, SC. In 2008, CSR will be used to empty two of these waste tanks in preparation for final closure. The two waste tanks chosen to undergo this process have previously leaked small amounts of nuclear waste from the primary tank into an underground secondary containment pan. CSR involves adding aqueous oxalic acid to the waste tank in order to dissolve the remaining sludge heel. The resultant acidic waste solution is then pumped to another waste tank where it will be neutralized and then stored awaiting further processing. The waste tanks to be cleaned have a storage capacity of 2.84E+06 liters (750,000 gallons) and a target sludge heel volume of 1.89E+04 liters (5,000 gallons) or less for the initiation of CSR. The purpose of this paper is to describe the CSR process and to discuss the most significant technical issues associated with the development of CSR.

    2010-01-01

    Localized, bilateral, painless, nonpruritic and symmetric papuloid lesions in the posteromedial part of the foot are the clinical features of benign plantar nodules of the heel in children. They are probably congenital; they are asymptomatic and benign. We present 18 children with posteromedial nodules of the heel, 15 bilateral. Mean age was 45.31+/-53.49 months. The reason for the consultation was the lump itself in 10 of the cases. Thirteen were asymptomatic and five presented transient tenderness to pressure. Radiographs were nonspecific in all cases. Sonography showed an accumulation of tissue similar to subcutaneous cell tissue, compatible with fat. MRI was performed in one case, showing an accumulation of fatty tissue similar to subcutaneous cell tissue. Follow-up time was 5.44+/-3.78 years (range 2-16 years). At the end of follow-up, all the patients are asymptomatic with normal functional outcome and with the lump persisting in all but one. In conclusion, a sonographic study is sufficient to diagnose this type of mass, without the need for biopsy and/or surgical exeresis to distinguish fatty tissue from another type of consistency. Subsequent studies should aim at showing piezogenic, hamartomatous or congenital fat herniation aetiology of these typical lumps, probably normal variant of normality. PMID:19741551

    [Purpose] We aimed to evaluate the difference in the muscle activity between the double-leg heel raise (DHR) and treadmill walking. [Subjects] Thirty healthy males aged 21.5 ± 1.6 years (body mass 63.6 ± 9.3 kg, height 171.0 ± 4.5 cm) participated in the study. [Methods] Electromyograms were simultaneously recorded from both heads of the gastrocnemius and the soleus of the right side during the DHR and treadmill walking. The DHR conditions were maximum plantar flexion (MPF), 3/4 MPF, 2/4 MPF, and 1/4 MPF, and the walking speeds were 20, 40, 60, 80, and 100 m/min. [Results] The muscle activity during the DHR and walking significantly increased with increments in the height of the heel raise and walking speed, respectively. Comparison of the muscle activity at MPF with that at each walking speed revealed that the muscle activity in the soleus and gastrocnemius medial head during walking exceeded that during the DHR in less than 3.3% of cases. [Conclusion] The DHR test is useful for evaluating the ankle plantar flexor activity necessary for walking. PMID:26157255

    Bone loss has been shown to be associated with chronic liver disease (CLD) caused by ethanol consumption or viral infection, and trabecular bone is affected more than cortical bone. We therefore used calcaneal ultrasound to compare the bone status of 54 males and 20 females with CLD in northern Nigeria with 88 age- and gender-matched healthy controls. Serum levels of bone-specific alkaline phosphatase (BSAP) and the N-terminal telopeptide of type-1 collagen (NTx) were also measured to estimate relative rates of bone synthesis and turnover, respectively. The mean stiffness index (SI) of the males with CLD and the male controls were not different; however, the mean SI of the female subjects with CLD was lower than for the female controls (101 vs. 86, p=0.003). The levels of NTx and BSAP were markedly elevated in the males, but not in the females, with CLD. Liver function tests did not correlate with ultrasound parameters or biochemical markers of bone metabolism. These results show that Nigerian women, but not males, with CLD have decreased bone density as assessed by calcaneal ultrasound; however, the high rate of bone turnover in Nigerian males with CLD indicates that they are at risk for bone loss.

  11. Control of the motion of the body's center of mass in relation to the center of pressure during high-heeled gait.

    High-heeled shoes are associated with instability and falling, leading to injuries such as fracture and ankle sprain. Knowledge of the motion of the body's center of mass (COM) with respect to the center of pressure (COP) during high-heeled gait may offer insights into the balance control strategies and provide a basis for approaches that minimize the risk of falling and associated adverse effects. The study aimed to investigate the influence of the base and height of the heels on the COM motion in terms of COM-COP inclination angles (IA) and the rate of change of IA (RCIA). Fifteen females who regularly wear high heels walked barefoot and with narrow-heeled shoes with three heel heights (3.9cm, 6.3cm and 7.3cm) while kinematic and ground reaction force data were measured and used to calculate the COM and COP, as well as the temporal-distance parameters. The reduced base of the heels was found to be the primary factor for the reduced normalized walking speed and the reduced frontal IA throughout the gait cycle. This was achieved mainly through the control of the RCIA during double-leg stance (DLS). The heel heights affected mainly the peak RCIA during DLS, which were not big enough to affect the IA. These results suggest young adults adopt a conservative strategy for balance control during narrow-heeled gait. The results will serve as baseline data for future evaluation of patients and/or older adults during narrow-heeled gait with the aim of reducing the risk of falling. PMID:23337731

    Beer, D; Bettschart, V

    2001-01-01

    The doctor on duty conducting home visits is frequently asked to care for patients with non-traumatic severe abdominal pain. For this reason, visiting doctors should be able to recognize tell-tale alarm signs, evaluate ailments that call for surgical referral to--particularly those that require emergency surgery--and, if necessary, perform simple paraclinical exams at the patient's bedside. In the case of intense abdominal pain requiring a rapid and effective "analgesia", the doctor should be able to administer an opiate, without of the surgical unit impairing the judgement. When hospitalisation or referral for surgery is not necessary, a re-evaluation at 12 to 36 hours later should be offered. PMID:11234707

  13. Neck pain

    PubMed Central

    2008-01-01

    Introduction Non-specific neck pain has a postural or mechanical basis and affects about two thirds of people at some stage, especially in middle age. Acute neck pain resolves within days or weeks, but may become chronic in about 10% of people. Whiplash injuries follow sudden acceleration–deceleration of the neck, such as in road traffic or sporting accidents. Up to 40% of people continue to report symptoms 15 years after the accident, although this varies between countries. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for people with non-specific neck pain without severe neurological deficit? What are the effects of treatments for acute whiplash injury? What are the effects of treatments for chronic whiplash injury? What are the effects of treatments for neck pain with radiculopathy? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 91 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of the evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, biofeedback, drug treatments (analgesics, antidepressants, epidural steroid injections, muscle relaxants, non-steroidal anti-inflammatory drugs [NSAIDs]), early mobilisation, early return to normal activity, exercise, heat or cold, manipulation (alone or plus exercise), mobilisation, multimodal treatment, patient education, percutaneous radiofrequency neurotomy, physical treatments, postural techniques (yoga, pilates, Alexander technique), pulsed electromagnetic field (PEMF) treatment, soft collars and special pillows, spray and stretch, surgery, traction, and transcutaneous electrical nerve stimulation (TENS).

    1993-04-01

    Seven patients who had surgery for malignant skin tumors of the heel were followed up for several years. The reconstructive procedure performed was repair of the large skin defect after excision of a tumor, by using a flexor digitorum brevis muscle flap and an overlying free graft. Although this procedure is a good method without any serious complications, no long-term follow-up data supporting this opinion have been reported. In this study, plantar flexion of the toes and flattening of the plantar arch appeared 3 months after surgery and developed for 1 year, and the patients complained of easy fatigability in walking and difficulty in going up stairs. These sequelae were probably due to sacrifice of the flexor digitorum brevis muscle. We feel that this procedure should be replaced by another procedure that does not sacrifice any muscle, for example, that using a medial plantar flap. PMID:8512293

    Distant metastases from laryngeal carcinoma are frequently seen in the lung, bone and liver, while skin metastases are rarely observed. In these cases presented as case reports in the literature, the supradiaphragmatic region is usually involved. Skin metastasis in lower extremity has only been reported in a few cases. While being an indicator of poor prognosis, skin metastasis is also considered as a messenger of distant organ metastasis. Survival is very short after development of skin metastasis. In our case, nodular skin metastasis was found both in the superior-lateral margin of the left patella and in the right heel. This is the first case reported in the literature on laryngeal carcinoma metastasizing to these localizations. PMID:20361886

  16. Preventing healthcare-associated transmission of the Middle East Respiratory Syndrome (MERS): Our Achilles heel.

    2016-01-01

    Middle East Respiratory Syndrome (MERS) coronavirus is the most recent among the Coronaviridae family to jump species and infect humans. Major healthcare associated MERS outbreaks have occurred in the Middle East and Korea that affected both patients and healthcare workers. These outbreaks were characterized by intra and inter-hospital spread and were exacerbated specifically by overcrowding, delayed diagnosis and appropriate use of personal protective equipment. Recent experience with this virus emphasizes the importance of compliance with infection control practices and with other interventions addressing patient triage, placement and flow within and between healthcare facilities. Our Achilles heel remains compliance with the best infection prevention practices and their harmonization with patient flow. Both infection prevention compliance and maintenance of patient flow are critical in preventing healthcare-associated transmission of many of these emerging infectious diseases, including MERS.

    Pain is a unique somatosensory perception that can dramatically affect our ability to function. It is also a necessary perception, without which we would do irreparable damage to ourselves. In this article, the authors assess the impact of pain on function of the hand. Pain can be categorized into acute pain, chronic pain, and neuropathic pain. Hand function and objective measurements of hand function are analyzed as well as the impact of different types of pain on each of these areas. PMID:26611383

    Aims/Introduction Although male diabetic patients have an increased risk of fracture, there is little information about this in the literature. The association between heel bone stiffness and the lifestyle of male patients with diabetes was evaluated. Materials and Methods The study included 108 participants with type 2 diabetes mellitus patients and 168 age-adjusted, healthy male volunteers. None of the participants had a history of osteoporosis or other severe diseases. Heel bone stiffness was examined by quantitative ultrasound, and each participant completed a health interview survey questionnaire. Bone stiffness was taken as an indicator of bone strength. Stepwise regression analysis was used to investigate associations between bone stiffness and lifestyle-related factors, such as sunlight exposure, intake of milk or small fish, regular exercise, cigarette smoking, consumption of alcohol, and number of remaining teeth. Results Bone stiffness showed a significant negative association with cigarette smoking [standardized coefficient (SC) = −0.297, F-value (F) = 10.059] and age (SC = −0.207, F = 7.565) in diabetic patients. Bone stiffness showed a significant negative association with age (SC = −0.371, F = 12.076) and height (SC = −0.193, F = 7.898), as well as a significant positive association with sunlight exposure (SC = 0.182, F = 9.589) and intake of small fish (SC = 0.170, F = 7.393) in controls. Conclusions These findings suggest that cigarette smoking and age are negatively associated with bone stiffness in Okinawan male patients with type 2 diabetes mellitus. PMID:25802722

  20. Central Neuropathic Pain Syndromes.

    2016-03-01

    Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury. This review focuses on unique clinical features that help distinguish central neuropathic pain. The most common clinical central pain syndromes-central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain-are reviewed in detail. Recent progress in understanding of the pathogenesis of central neuropathic pain is reviewed, and pharmacological, surgical, and neuromodulatory treatments of this notoriously difficult to treat pain syndrome are discussed.

  1. Descending pain modulation and chronification of pain

    2015-01-01

    Purpose of review Chronic pain is an important public health problem that negatively impacts quality of life of affected individuals and exacts an enormous socio-economic cost. Currently available therapeutics provide inadequate management of pain in many patients. Acute pain states generally resolve in most patients. However, for reasons that are poorly understood, in some individuals, acute pain can transform to a chronic state. Our understanding of the risk factors that underlie the development of chronic pain is limited. Recent studies have suggested an important contribution of dysfunction in descending pain modulatory circuits to pain ‘chronification’. Human studies provide insights into possible endogenous and exogenous factors that may promote the conversion of pain into a chronic condition. Recent findings Descending pain modulatory systems have been studied and characterized in animal models. Human brain imaging techniques, deep brain stimulation and the mechanisms of action of drugs that are effective in the treatment of pain confirm the clinical relevance of top-down pain modulatory circuits. Growing evidence supports the concept that chronic pain is associated with a dysregulation in descending pain modulation. Disruption of the balance of descending modulatory circuits to favour facilitation may promote and maintain chronic pain. Recent findings suggest that diminished descending inhibition is likely to be an important element in determining whether pain may become chronic. This view is consistent with the clinical success of drugs that enhance spinal noradrenergic activity, such as serotonin/norepinephrine reuptake inhibitors (SNRIs), in the treatment of chronic pain states. Consistent with this concept, a robust descending inhibitory system may be normally engaged to protect against the development of chronic pain. Imaging studies show that higher cortical and subcortical centres that govern emotional, motivational and cognitive processes communicate directly with descending pain modulatory circuits providing a mechanistic basis to explain how exogenous factors can influence the expression of chronic pain in a susceptible individual. Summary Preclinical studies coupled with clinical pharmacologic and neuroimaging investigations have advanced our understanding of brain circuits that modulate pain. Descending pain facilitatory and inhibitory circuits arising ultimately in the brainstem provide mechanisms that can be engaged to promote or protect against pain ‘chronification’. These systems interact with higher centres, thus providing a means through which exogenous factors can influence the risk of pain chronification. A greater understanding of the role of descending pain modulation can lead to novel therapeutic directions aimed at normalizing aberrant processes that can lead to chronic pain. PMID:24752199

    La rupture du tendon calcanéen est une des lésions les plus fréquentes en pathologie du sport, les deux options thérapeutiques classiques sont le traitement orthopédique et la chirurgie à ciel ouvert. Dans le but de minimiser ces complications, des techniques mini-invasives de ténorraphie percutanée ont été proposées dont les résultats sont encourageants. Il s'agit d'une étude rétrospective d'une série de cas de rupture sous cutanée du tendon d'Achille s’étalant de Avril 2005 au Juin 2012 concernant 67 patients; 11 femmes et 56 hommes avec un âge moyen de 41 ans. La cause principale était un accident de sport dans 45 cas. Le diagnostic était évident à l'examen chez tous les patients. Dans deux cas il s'agissait d'une rerupture survenant à 1 et 5 ans d'un traitement orthopédique. Dans un cas il s'agissait d'une rerupture survenant après une ténorraphie percutanée. Dans deux cas il s'agissait d'une rupture sur tendinopathie chronique. Tous les patients avaient bénéficié d'une radio de la cheville qui avait montré une horizontalisation du calcanéum chez 5 patients et surtout elle n'avait pas montré de fracture associée, alors que 15 patients avaient bénéficié d'une échographie qui a confirmé le diagnostic. Tous les patients avaient été opérés dans un délai de moins de 48 heures Une ténorraphie percutanée a été pratiqué chez tous les patients. Le recul moyen est de 43 mois, trois patients ont été perdus de vue Nous avons noté une reprise des activités professionnelle effective en moyen 90 jours après l'intervention et celle des activités sportive à 6 mois en moyenne L’état cutané local a été jugée bon dans 63 cas. Par ailleurs les complications ont été marquées par un seul cas d'infection ayant nécessité une reprise chirurgical a été noté mise à plat, trois cas de rerupture repris par suture à ciel ouvert, un cas d'algodystrophie et un cas de tendinopathie Il n'y a eu aucune complication thromboembolique ni neurologique. Il n'existe pas de réel consensus concernant la prise en charge des ruptures du tendon calcanéen. Ainsi, La ténorraphie percutanée du tendon calcanéen est une méthode simple rapide et efficace, elle allie les avantages de la chirurgie à ciel ouvert en termes de pourcentage de rerupture et les avantages du traitement fonctionnel en rapport avec un faible risque infectieux.

    Disorders of the joint at the base of the hallux are common in active patients. Great-toe sprains (turf toe) can range from mild to severe with associated fractures. Hallux rigidus, a painful flexion deformity, is often seen in athletes who stress the joint repetitively. Heredity may predispose athletes to hallux valgus (bunion) but improper footwear, injury, and hyperpronation can also be implicated. Weight-bearing activities, climbing stairs, or wearing high-heeled shoes will aggravate sesamoiditis. Stress fractures, osteochondral defects, and gout are other causes of toe pain. X-rays are essential for accurate diagnosis. Nonoperative measures can reduce pain, but surgery is an option for recalcitrant cases. PMID:20086649

    It is estimated that 23 million Germans suffer from chronic pain. A recent survey has revealed that 30 % of chronic pain patients are dissatisfied with their pain management. Furthermore, five million Germans suffer from neuropathic pain, 20 % of whom are inadequately treated. Pain is also a symptom of many dermatologic diseases, which is mostly somatic and may be classified as mild in the majority of cases. Nevertheless, research on the quality of life (QoL) has increasingly shown a marked impairment of QoL by moderate pain such as in psoriatic arthritis. -Severe pain is associated with herpes zoster (shingles), leg ulcers, and pyoderma gangrenosum. This article addresses the basics of pain classification and, in a short excerpt, pain transduction/transmission and modulation. The use of standardized diagnostic -scales is recommended for the purpose of recording and monitoring pain intensity, which allows for the optimization of therapy and consistent interdisciplinary -communication. Any dermatology residency program includes the acquisition of knowledge and skills in pain management. This review therefore aims to present fundamental therapeutic concepts based on the expanded WHO analgesic ladder, and describes a step-wise therapeutic approach and combination therapies. The article focuses on the pain management of the above-mentioned severely painful, conservatively treated dermatoses. Besides well-established therapeutic agents and current -therapeutic standards, it discusses specific options based on guidelines (where available). Current knowledge on peri- and postoperative pain management is briefly outlined. This article addresses: ▸ The fundamentals of the classification and neurophysiology of pain; ▸ Standards for pain documentation in children and adults; ▸ General standards for pharmaceutical pain management; ▸ Current specific treatment options for postherpetic neuralgia, leg ulcers, and -pyoderma gangrenosum in conjunction with the expanded WHO analgesic -ladder.

    Regular assessment for the presence of pain and response to pain management strategies should be high priority in cancer patients. Pain is a multidimensional experience in cancer patients. Pain management will be most effective when treatments are individualized after exploring the various physical and non-physical components of pain, and the patient and family are educated and involved in decision making. This article discusses the various issues that are pertinent to the assessment of pain in cancer patients. PMID:22585314

  14. The potential influence of the heel counter on internal stress during static standing: a combined finite element and positional MRI investigation.

    2007-01-01

    Confinement of the heel due to the counter of the shoe is believed to influence heel pad biomechanics. Using a two-dimensional finite element model of the heel pad and shoe during a simulation of static standing, the aim of this study was to quantify the potential effect of confinement on internal heel pad stress. Non-weightbearing MRI and weightbearing MRI with plantar pressure and ground reaction force data were recorded for a single subject. The non-weightbearing MRI was used to create two FE models of the heel pad, using either homogeneous or composite material properties. The composite model included a distinction in material properties between fat pad and skin. Vertical and medial-lateral forces, as measured on the subject's heel, were applied to the models and vertical compressive strains for both models were comparable with those observed by weightbearing MRI. However, only for the composite model was the predicted plantar pressure distribution comparable with measured data. The composite model was therefore used in further analyses. In this composite model, the internal stresses were located mainly in the skin and were predominantly tensile in nature, whereas the stress state in the fat pad approached hydrostatic conditions. A representation of a running shoe, including an insole, midsole and heel counter was then added to the composite heel pad to form the shod model. In order to investigate the counter effect, the load was applied to the shod model with and without the heel counter. The effect of the counter on peak stress was to elevate compression (0-50%), reduce tension (22-34%) and reduce shear (22-28%) in the skin. In addition, the counter reduced both compressive (20-40%) and shear (58-80%) stress in the fat pad and tension in the fat pad remained negligible. Taken together the results indicate that a well-fitted counter works in sympathy with the internal structure of the heel pad and could be an effective reducer of heel pad stress. However, further research needs to be undertaken to assess the long-term effects on the soft-tissues, practicalities of achieving good fit and behavior under dynamic events. PMID:17362970

    Orofacial pain refers to pain associated with the soft and hard tissues of the head, face, and neck. It is a common experience in the population that has profound sociologic effects and impact on quality of life. New scientific evidence is constantly providing insight into the cause and pathophysiology of orofacial pain including temporomandibular disorders, cranial neuralgias, persistent idiopathic facial pains, headache, and dental pain. An evidence-based approach to the management of orofacial pain is imperative for the general clinician. This article reviews the basics of pain epidemiology and neurophysiology and sets the stage for in-depth discussions of various painful conditions of the head and neck. PMID:23809298

    The Savannah River Site (SRS) will remove sludge as part of waste tank closure operations. Typically the bulk sludge is removed by mixing it with supernate to produce a slurry, and transporting the slurry to a downstream tank for processing. Experience shows that a residual heel may remain in the tank that cannot be removed by this conventional technique. In the past, SRS used oxalic acid solutions to disperse or dissolve the sludge heel to complete the waste removal. To better understand the actual conditions of oxalic acid cleaning of waste from carbon steel tanks, the authors developed and conducted an experimental program to determine its effectiveness in dissolving sludge, the hydrogen generation rate, the generation rate of other gases, the carbon steel corrosion rate, the impact of mixing on chemical cleaning, the impact of temperature, and the types of precipitates formed during the neutralization process. The test samples included actual SRS sludge and simulated SRS sludge. The authors performed the simulated waste tests at 25, 50, and 75 C by adding 8 wt % oxalic acid to the sludge over seven days. They conducted the actual waste tests at 50 and 75 C by adding 8 wt % oxalic acid to the sludge as a single batch. Following the testing, SRS conducted chemical cleaning with oxalic acid in two waste tanks. In Tank 5F, the oxalic acid (8 wt %) addition occurred over seven days, followed by inhibited water to ensure the tank contained enough liquid to operate the mixer pumps. The tank temperature during oxalic acid addition and dissolution was approximately 45 C. The authors analyzed samples from the chemical cleaning process and compared it with test data. The conclusions from the work are: (1) Oxalic acid addition proved effective in dissolving sludge heels in the simulant demonstration, the actual waste demonstration, and in SRS Tank 5F. (2) The oxalic acid dissolved {approx} 100% of the uranium, {approx} 100% of the iron, and {approx} 40% of the manganese during a single contact in the simulant demonstration. (The iron dissolution may be high due to corrosion of carbon steel coupons.) (3) The oxalic acid dissolved {approx} 80% of the uranium, {approx} 70% of the iron, {approx} 50% of the manganese, and {approx} 90% of the aluminum in the actual waste demonstration for a single contact. (4) The oxalic acid dissolved {approx} 100% of the uranium, {approx} 15% of the iron, {approx} 40% of the manganese, and {approx} 80% of the aluminum in Tank 5F during the first contact cycle. Except for the iron, these results agree well with the demonstrations. The data suggest that a much larger fraction of the iron in the sludge dissolved, but it re-precipitated with the oxalate added to Tank 5F. (5) The demonstrations produced large volumes (i.e., 2-14 gallons of gas/gallon of oxalic acid) of gas (primarily carbon dioxide) by the reaction of oxalic acid with sludge and carbon steel. (6) The reaction of oxalic acid with carbon steel produced hydrogen in the simulant and actual waste demonstrations. The volume produced varied from 0.00002-0.00100 ft{sup 3} hydrogen/ft{sup 2} carbon steel. The hydrogen production proved higher in unmixed tanks than in mixed tanks.

  17. Relationship between self-reported high-heeled shoe use and bone mineral density using quantitative ultrasound at a community health fair.

    This is the first known study to examine the relationship between high-heel use and bone mineral density (BMD). Because women are disproportionately affected by osteoporosis, it is important to identify possible modifiable behaviors of women that may adversely affect bone health. Many studies have shown changes in body mechanics when wearing high-heeled shoes in comparison to normal gait. Because the composition of bone changes according to mechanical load and muscle activity, this study investigates whether wearing high heels may alter BMD. Two hundred and twenty-one participants at a community health fair in Lansing, Michigan, were surveyed on high-heel use and bone health risk (gender, thin/small frame, fair skin, family history of fracture, smoking history, walking, dairy consumption, and early menopause or oopherectomy at <45 years old). Quantitative ultrasound (QUS) of the heel by Hologic's Sahara Sonometer was used to measure BMD. The mean age was 45.2 (SD 13.7) years, and the majority of participants were female (208, 94 %). A significant difference between mean BMD and high-heel use was not found. Independent correlations existed between fair skinned/sunburn easily and BMD, r(212) = -0.14, p = 0.038, as well as history of smoking and BMD, r(212) = -0.14, p = 0.042. Bone health risk score was strongly correlated with heel use binary variable "yes/no," r(210) = 0.21, p = 0.003. Our study suggests that wearing high-heeled shoes does not lead to appreciable differences in BMD among community health fair participants as assessed by QUS. PMID:22983265

    Because of the increased popularity of running, interest has focussed on ways of reducing injurious skeletal shocks. This paper examines heel and toe strike running styles and the effect of shock attenuating materials in reducing foot/floor contact forces and skeletal shocks. Using a force plate and an accelerometer, 18volunteers (10 men, 8 women) were studied and the following observations made. Firstly, toe striking reduced the skeletal transients and the rate of rise of foot loading. Secondly, the three materials studied (PPT, Viscolas and Cleron) all reduced the rate of foot loading in heel strike, but only one (PPT) affected the skeletal transient peak height during toe strike. No other significant results were obtained. PMID:23915893

    1986-01-01

    The cyclic impacts induced by heel strike when walking were studied using both a high-resonance-frequency force plate and a low-mass skin-mounted accelerometer. The data were computer analyzed. The results showed that during normal human walking, the locomotor system is subjected to repetitive impact loads at heel strike, lasting about 5 ms and consisting of frequency spectra up to and above 100 Hz. The natural shock-absorbing structures in the musculoskeletal system have viscoelastic time-dependent mechanical behavior, which is relatively ineffective in withstanding sudden impulsive loads. Degenerative joint diseases may thus be seen as a late clinical result of fatigue failure of the natural shock absorbers, submitted to deleterious impacts over a period of time. PMID:3964043

    Based on the psychoanalytic reading of Homer’s Iliad whose principal theme is “Achilles’ rage” (the semi-mortal hero invulnerable in all of his body except for his heel, hence “Achilles’ heel” has come to mean a person’s principal weakness), we aimed to assess whether “narcissistic rage” has an impact on several psychosocial variables in patients with severe physical illness across time. In 878 patients with cancer, rheumatological diseases, multiple sclerosis, inflammatory bowel disease, and glaucoma, we assessed psychological distress (SCL-90 and GHQ-28), quality of life (WHOQOL-BREF), interpersonal difficulties (IIP-40), hostility (HDHQ), and defense styles (DSQ). Narcissistic rage comprised DSQ “omnipotence” and HDHQ “extraverted hostility”. Hierarchical multiple regressions analyses were performed. We showed that, in patients with disease duration less than one year, narcissistic rage had a minor impact on psychosocial variables studied, indicating that the rage was rather part of a “normal” mourning process. On the contrary, in patients with longer disease duration, increased rates of narcissistic rage had a great impact on all outcome variables, and the opposite was true for patients with low rates of narcissistic rage, indicating that narcissistic rage constitutes actually an “Achilles’ Heel” for patients with long-term physical illness. These findings may have important clinical implications. PMID:19936167

  3. Dendritic cells as Achilles' heel and Trojan horse during varicella zoster virus infection.

    PubMed

    Schönrich, Günther; Raftery, Martin J

    2015-01-01

    Varicella zoster virus (VZV), a human alphaherpesvirus, causes varicella and subsequently establishes latency within sensory nerve ganglia. Later in life VZV can reactivate to cause herpes zoster. A reduced frequency of VZV-specific T cells is strongly associated with herpes zoster illustrating that these immune cells are central to control latency. Dendritic cells (DCs) are required for the generation of VZV-specific T cells. However, DCs can also be infected in vitro and in vivo allowing VZV to evade the antiviral immune response. Thus, DCs represent the immune systems' Achilles heel. Uniquely among the human herpesviruses, VZV infects both DCs and T cells, and exploits both as Trojan horses. During primary infection VZV-infected DCs traffic to the draining lymph nodes and tonsils, where the virus is transferred to T cells. VZV-infected T cells subsequently spread infection throughout the body to give the typical varicella skin rash. The delicate interplay between VZV and DCs and its consequences for viral immune evasion and viral dissemination will be discussed in this article. PMID:26005438

    2009-12-18

    Preliminary studies in the EM-21 Alternative Chemical Cleaning Program have focused on understanding the dissolution of Hematite (a primary sludge heel phase) in oxalic acid, with a focus on minimizing oxalic acid usage. Literature reviews, thermodynamic modeling, and experimental results have all confirmed that pH control, preferably using a supplemental proton source, is critical to oxalate minimization. With pH control, iron concentrations as high as 0.103 M have been obtained in 0.11 M oxalic acid. This is consistent with the formation of a 1:1 (iron:oxalate) complex. The solubility of Hematite in oxalic acid has been confirmed to increase by a factor of 3 when the final solution pH decreases from 5 to below 1. This is consistent with literature predictions of a shift in speciation from a 1:3 to 1:1 as the pH is lowered. Above a solution pH of 6, little Hematite dissolves. These results emphasize the importance of pH control in optimizing Hematite dissolution in oxalic acid.

    Mixtures of oxalic acid with nitric acid have been shown to be superior to oxalic acid alone for the dissolution of iron-rich High Level Waste sludge heels. Optimized conditions resulting in minimal oxalate usage and stoichiometric iron dissolution (based on added oxalate ion) have been determined for hematite (a primary sludge iron phase) in oxalic/nitric acid mixtures. The acid mixtures performed better than expected based on the solubility of hematite in the individual acids through a synergistic effect in which the preferred 1:1 Fe:oxalate complex is formed. This allows for the minimization of oxalate additions to the waste stream. Carbon steel corrosion rates were measured in oxalic/nitric acid mixtures to evaluate the impacts of chemical cleaning with these solutions on waste tank integrity. Manageable corrosion rates were observed in the concentration ranges of interest for an acid contact timescale of 1 month. Kinetics tests involving hematite and gibbsite (a primary sludge aluminum phase) have confirmed that {ge}90% solids dissolution occurs within 3 weeks. Based on these results, the chemical cleaning conditions recommended to promote minimal oxalate usage and manageable corrosion include: 0.5 wt. % oxalic acid/0.175 M nitric acid mixture, 50 C, 2-3 week contact time with agitation.

    This qualitative research aimed to study the meaning, the characteristics, and the dimensions of pain from a Thai point of view. It was conducted under the research project on the development of the quality of pain management for people in the hospital. The subjects were 62 patients, experiencing pain and receiving treatment in 4 hospitals in northeast Thailand. Data were analyzed through content analysis. The findings included: 1) concept from experience of pain, perceived pain as suffering physically and psychologically, 2) different characteristics between acute and chronic pain, 3) four levels of pain intensity: mild, moderate, high and severe, 4) pain effects on four dimensions: physical, psychological, behavioral and societal (family-social-economy), 5) two factors related to pain: alleviating factor and predisposing factor, and 6) pain management relies on beliefs, culture and religion i.e. good deeds in Buddhism affected six dimensions: physical, psychological, social, spiritual, treatment seeking and asking health personnel for help. The results of the present study revealed the influence of culture beliefs on the meaning of pain, pain characteristics, and the effects of pain as well as pain management in terms of cultural contexts. The findings may be implemented for the development of pain assessment and the model development of pain management more appropriately according to cultural contexts. PMID:24386747

    STUDY DESIGN Experimental laboratory study using a cross-sectional design. OBJECTIVES To compare foot kinematics, using 3-dimensional tracking methods, during a bilateral heel rise between participants with posterior tibial tendon dysfunction (PTTD) and participants with a normal medial longitudinal arch (MLA). BACKGROUND The bilateral heel rise test is commonly used to assess patients with PTTD; however, information about foot kinematics during the test is lacking. METHODS Forty-five individuals volunteered to participate, including 30 patients diagnosed with unilateral stage II PTTD (mean ± SD age, 59.8 ± 11.1 years; body mass index, 29.9 ± 4.8 kg/m2) and 15 controls (mean ± SD age, 56.5 ± 7.7 years; body mass index, 30.6 ± 3.6 kg/m2). Foot kinematic data were collected during a bilateral heel rise task from the calcaneus (hindfoot), first metatarsal, and hallux, using an Optotrak motion analysis system and Motion Monitor software. A 2-way mixed-effects analysis of variance model, with normalized heel height as a covariate, was used to test for significant differences between the normal MLA and PTTD groups. RESULTS The patients in the PTTD group exhibited significantly greater ankle plantar flexion (mean difference between groups, 7.3°; 95% confidence interval [CI]: 5.1° to 9.5°), greater first metatarsal dorsiflexion (mean difference between groups, 9.0°; 95% CI: 3.7° to 14.4°), and less hallux dorsiflexion (mean difference, 6.7°; 95% CI: 1.7° to 11.8°) compared to controls. At peak heel rise, hindfoot inversion was similar (P = .130) between the PTTD and control groups. CONCLUSION Except for hindfoot eversion/inversion, the differences in foot kinematics in participants with stage II PTTD, when compared to the control group, mainly occur as an offset, not an alteration in shape, of the kinematic patterns.

    Hispanic adults experience significant pain, but little is known about their pain during hospitalization. The purpose of this research was to describe Hispanic inpatients' pain intensity and compare their pain intensity with that of non-Hispanic patients. A post hoc descriptive design was used to examine 1,466 Hispanic inpatients' medical records (63.2% English speakers) and 12,977 non-Hispanic inpatients' medical records from one hospital for 2012. Mean documented pain intensity was mild for both Hispanic and non-Hispanic inpatients. Pain intensity was greater for English-speaking Hispanic patients than Spanish speakers. The odds of being documented with moderate or greater pain intensity decreased 30% for Spanish-speaking patients. Greater pain intensity documented for English-speaking Hispanic inpatients suggests underreporting of pain intensity by Spanish-speaking patients. Practitioners should use interpreter services when assessing and treating pain with patients who speak languages different from the practitioners' language(s). PMID:24958761

    Purpose: Radiation therapy is well established in the treatment of painful plantar fasciitis or heel spur. A retrospective analysis was conducted to investigate the effect of field definition on treatment outcome and to determine the impact of factors potentially involved. Methods and Materials: A review of treatment data of 250 patients (285 heels) with a mean follow-up time of 11 months showed that complete symptom remission occurred in 38%, partial remission in 32%, and no change in 19% (11% were lost to follow-up). Variables such as radiologic evidence of plantar spurs, their length, radiation dose, field size, age, sex, and onset of pain before administration of radiation therapy were investigated in univariate and multivariate regression analyses. Results: Treatment response depended upon age >53 years, length of heel spur ≤6.5 mm (or no radiologic evidence of a heel spur), and onset of pain <12 months before radiation therapy. Patients with these clinical prerequisites stood a 93% chance of clinical response. Without these prerequisites, only 49% showed any impact. No influence of field size on treatment outcome became evident. Conclusion: Patients with short plantar heel spurs benefit from radiation therapy equally well as patients without any radiologic evidence. Moreover, smaller field sizes have the same positive effect as commonly used large field definitions covering the entire calcaneal bone. This leads to a recommendation of a considerable reduction of field size in future clinical practice.

    This study measured tissue properties of different anatomies of heels in amputated lower limbs of diabetic patients before and after hyaluronic acid (HA) or normal saline (NS) injections. Seven amputated lower limbs from six diabetic patients constituted the experimental group and one amputated lower limb from a diabetic patient served as the control. The limbs were placed in a fixation platform. A 5-12 MHz linear-array ultrasound transducer controlled by a stepping motor was used to load and unload tested heels. The loading-unloading velocity was 6 mm/s and the maximum loading stress was 178 kPa. Loading-unloading tests were performed before and after 1 mL HA injections into heels in the experimental group. The control limb underwent the same test before and after 1 mL NS injection. The unloaded thickness and Young's modulus of the macrochambers, microchambers and heel pads were determined before and after the interventions. The unloaded thickness of the macrochambers and the heel pad increased significantly (p = 0.012) after HA injection. The Young's modulus of the macrochambers decreased nonsignificantly after HA injections. Similar thickness and tissue stiffness changes were observed in the control limb. The baseline heel-pad energy dissipation ratio (EDR(hp)) was 81.3 1.3% and decreased significantly (p = 0.012) to 73.1 1.7% after HA injections. The EDR(hp) in the control increased after NS injection. Histologic examinations revealed localized HA accumulation in the macrochambers with an extension into the adjacent fibrous septa. Injection of HA can increase tissue thickness and enhance heel-pad tissue resilience. PMID:22502884

    Purpose Genome-wide association studies (GWAS) have identified 6q25, which incorporates the oestrogen receptor α gene (ESR1), as a quantitative trait locus for areal bone mineral density (BMDa) of the hip and lumbar spine. The aim of this study was to determine the influence of this locus on other bone health outcomes; calcaneal ultrasound (QUS) parameters, radial peripheral quantitative computed tomography (pQCT) parameters and markers of bone turnover in a population sample of European men. Methods Eight single nucleotide polymorphisms (SNP) in the 6q25 locus were genotyped in men aged 40–79 years from 7 European countries, participating in the European Male Ageing Study (EMAS). The associations between SNPs and measured bone parameters were tested under an additive genetic model adjusting for centre using linear regression. Results 2468 men, mean (SD) aged 59.9 (11.1) years had QUS measurements performed and bone turnover marker levels measured. A subset of 628 men had DXA and pQCT measurements. Multiple independent SNPs showed significant associations with BMD using all three measurement techniques. Most notably, rs1999805 was associated with a 0.10 SD (95%CI 0.05, 0.16; p = 0.0001) lower estimated BMD at the calcaneus, a 0.14 SD (95%CI 0.05, 0.24; p = 0.004) lower total hip BMDa, a 0.12 SD (95%CI 0.02, 0.23; p = 0.026) lower lumbar spine BMDa and a 0.18 SD (95%CI 0.06, 0.29; p = 0.003) lower trabecular BMD at the distal radius for each copy of the minor allele. There was no association with serum levels of bone turnover markers and a single SNP which was associated with cortical density was also associated with cortical BMC and thickness. Conclusions Our data replicate previous associations found between SNPs in the 6q25 locus and BMDa at the hip and extend these data to include associations with calcaneal ultrasound parameters and radial volumetric BMD.

    Pain problems, especially posttraumatic headache, are very common following head trauma. Pain may be the most significant problem, more disabling than any brain or other injuries, and interfering with aspects of cognition or other function. However, posttraumatic headache and most other chronic posttraumatic pain problems remain poorly understood. This article reviews fundamental issues that should be considered in understanding the nature of chronic pain including the distinction between acute and chronic pain; neurobiological distinctions between the lateral and medial pain system; nociceptive versus neuropathic or other central pain; sensitization effects; the widely accepted view of chronic pain as a multidimensional subjective experience involving sensory, motivational-affective and cognitive-behavioral components; the problem of mind-body dualism; the role of psychosocial factors in the onset, maintenance, exacerbation or severity of pain; plus issues of response bias and malingering.

    In this article I clarify the concepts of 'pain', 'suffering', 'pains of body', 'pains of soul'. I explore the relevance of an ethic to the clinical setting which gives patients a strong prima facie right to freedom from unnecessary and unwanted pain and which places upon medical professionals two concomitant moral obligations to patients. First, there is the duty not to inflict pain and suffering beyond what is necessary for effective diagnosis, treatment and research. Next, there is the duty to do all that can be done to relieve all the pain and suffering which can be alleviated. I develop in some detail that individuality of pain sensitivity must be taken into account in fulfilling these obligations. I explore the issue of the relevance of informed consent and the right to refuse treatment to the matter of pain relief. And I raise the question of what conditions, if any, should override the right to refuse treatment where pain relief is of paramount concern. PMID:6710192

    This series of papers aims to provide the dental and medical teams with an update in pain, both acute and chronic orofacial conditions, relevant to dentistry and medicine. Pain is the most common symptom for patients presenting to their dentist, and is increasingly commonly presenting to doctors as well, in general practice and A & E departments. Most of the dental team take for granted their knowledge and ability to manage acute dental pain. However, the education and preparation in managing patients with chronic pain conditions remains poor in many medical and dental schools. Conversely, medics are better educated and exposed to chronic pain during their undergraduate education, however, with regards to orofacial pain education, exposure is diminishing due to decreased exposure to dentistry, ENT, otolaryngology, OMFS and oral surgery. Thus many clinical teams remain disadvantaged when diagnosing and managing orofacial pain. Clinical Relevance: Significant advances that have been made in understanding the pain mechanisms are not to be overlooked and have a huge impact on how we manage patients in pain. PMID:26058224

  15. On Heels and Toes: How Ants Climb with Adhesive Pads and Tarsal Friction Hair Arrays.

    PubMed

    Endlein, Thomas; Federle, Walter

    2015-01-01

    Ants are able to climb effortlessly on vertical and inverted smooth surfaces. When climbing, their feet touch the substrate not only with their pretarsal adhesive pads but also with dense arrays of fine hairs on the ventral side of the 3rd and 4th tarsal segments. To understand what role these different attachment structures play during locomotion, we analysed leg kinematics and recorded single-leg ground reaction forces in Weaver ants (Oecophylla smaragdina) climbing vertically on a smooth glass substrate. We found that the ants engaged different attachment structures depending on whether their feet were above or below their Centre of Mass (CoM). Legs above the CoM pulled and engaged the arolia ('toes'), whereas legs below the CoM pushed with the 3rd and 4th tarsomeres ('heels') in surface contact. Legs above the CoM carried a significantly larger proportion of the body weight than legs below the CoM. Force measurements on individual ant tarsi showed that friction increased with normal load as a result of the bending and increasing side contact of the tarsal hairs. On a rough sandpaper substrate, the tarsal hairs generated higher friction forces in the pushing than in the pulling direction, whereas the reverse effect was found on the smooth substrate. When the tarsal hairs were pushed, buckling was observed for forces exceeding the shear forces found in climbing ants. Adhesion forces were small but not negligible, and higher on the smooth substrate. Our results indicate that the dense tarsal hair arrays produce friction forces when pressed against the substrate, and help the ants to push outwards during horizontal and vertical walking.

    We review the evidence of botulinum toxins in the treatment of pain. Main indications of botulinum toxin treatment, dystonia and spasticity, involve pain. Increasing evidence suggests direct analgesic effects of botulinum. Botulinum inhibits release of pain mediators (substance P, CGRP, excitatory amino acids, ATP, noradrenaline). Clinical trials have consistently shown analgesic effect of botulinum toxin in post-stroke shoulder pain, bladder dysfunction, chronic migraine, neuropathic pain, bruxism and lateral epicondylitis. Other pain conditions have been studied with yet uncertain results. It seems that the number of patients who would benefit from botulinum toxin treatment will increase considerably in the future.

    It is now recognized that from the newborn period onwards, children are capable of experiencing pain. This includes the premature infant. The challenge for healthcare providers is to incorporate methods of pain assessment and treatment into their daily practices. The child's understanding of pain closely follows the cognitive and behavioral model developed by Jean Piaget. Based on these developmental stages, pain assessment measures have been developed. Pharmacologic advances have accompanied this improved understanding of infant, child, and adolescent psychology. While acute pain accounts for the majority of children's experiences, recurrent/chronic pain states do occur (e.g. sickle cell related and neuropathic) and can be effectively treated. PMID:9037997

    The purpose of our investigation was to prospectively review and compare the early outcomes of Sanders II and III closed displaced intra-articular calcaneal fractures (DIACFs) in a group of patients treated by open reduction and internal fixation with plate and screws using the extended lateral approach or the sinus tarsi approach (STA). Thirty-eight patients with DIACFs were prospectively enrolled and operatively treated using either the extended lateral approach or the STA. Patients underwent a careful clinical and radiographic examination and were evaluated according to the American Orthopaedic Foot and Ankle Society score, visual analog scale, and the Foot Function Index. The results from our study showed similar clinical and radiographic outcomes between the 2 groups. In our series, Sanders II and III DIACFs were sufficiently exposed using the STA to achieve anatomic reduction and stable fixation. The STA group had a lower incidence of wound complications (p ≥ .05), the surgical procedure was faster, and the waiting time to surgery was shorter (p ≤ .05). Despite the limited number of patients and the short follow-up period, our results suggest that the STA is a useful method for the treatment of DIACFs, with a low incidence of complications and results comparable to those for patients treated using the extended lateral approach.

    Flatfoot (pes planus) is one of the most important physical examination items for military new recruits in Taiwan. Currently, the diagnosis of flatfoot is mainly based on radiographic examination of the calcaneal-fifth metatarsal (CA–MT5) angle, also known as the arch angle. However, manual measurement of the arch angle is time-consuming and often inconsistent between different examiners. In this study, seventy male military new recruits were studied. Lateral radiographic images of their right and left feet were obtained, and mutual information (MI) registration was used to automatically calculate the arch angle. Images of two critical bones, the calcaneus and the fifth metatarsal bone, were isolated from the lateral radiographs to form reference images, and were then compared with template images to calculate the arch angle. The result of this computer-calculated arch angle was compared with manual measurement results from two radiologists, which showed that our automatic arch angle measurement method had a high consistency. In addition, this method had a high accuracy of 97% and 96% as compared with the measurements of radiologists A and B, respectively. The findings indicated that our MI registration measurement method cannot only accurately measure the CA–MT5 angle, but also saves time and reduces human error. This method can increase the consistency of arch angle measurement and has potential clinical application for the diagnosis of flatfoot. PMID:26126115

Although pharmacological pain management offers a significant relief in several pain-related diseases, many patients turn to its supplementation with complementary and alternative medicine. Botanicals used in pain therapy can contribute to restoring the quality of life to a patient and may effect and enhance conventional pain management. Herbal analgesic use in several pain-related diseases such as rheumatologic diseases, back pain, cancer, diabetic peripheral neuropathy and migraine will be discussed. In addition, this review describes botanicals with known analgesic activity for which randomized, placebo-controlled, double-blind trials assessing their efficacy in different pain-related diseases have been published and which have been recently evaluated in many systematic reviews with well-described methodology.

    Patients with blood-related cancers (BRC) suffer from a substantial symptom burden, including several pain syndromes sustained by different causes and pathogenetic mechanisms. So, with regard to pain, a multifaceted clinical scenario may be observed in this setting. Indeed, pain may be correlated to disease itself, to disease-associated complications, to iatrogenic causes or may be due to unrelated clinical conditions. A close diagnostic procedure for the assessment of the underlying causes of the pain and of its pathogenetic mechanisms may direct the treatment approach which should be based on a multidisciplinary management and requires the integration of etiology-targeted interventions and painkilling drugs. The World Health Organization's three-step analgesic ladder for cancer pain relief can provide adequate pain control using oral drugs in most patients with BRC on pain, although more complex interventions may be necessary for many difficult-to-treat pain syndromes which are not infrequently encountered in this setting.

    Cancer and its treatment exert a heavy psychological and physical toll. Of the myriad symptoms which result, pain is common, encountered in between 30% and 60% of cancer survivors. Pain in cancer survivors is a major and growing problem, impeding the recovery and rehabilitation of patients who have beaten cancer and negatively impacting on cancer patients’ quality of life, work prospects and mental health. Persistent pain in cancer survivors remains challenging to treat successfully. Pain can arise both due to the underlying disease and the various treatments the patient has been subjected to. Chemotherapy causes painful chemotherapy-induced peripheral neuropathy (CIPN), radiotherapy can produce late effect radiation toxicity and surgery may lead to the development of persistent post-surgical pain syndromes. This review explores a selection of the common causes of persistent pain in cancer survivors, detailing our current understanding of the pathophysiology and outlining both the clinical manifestations of individual pain states and the treatment options available.

    With the growing number of eldery patients in industrialized nations the incidence of geriatric, i.e. osteoporotic fractures is steadily on the rise. It is of great importance to understand the characteristics of hip fractures and to provide diagnostic tests for the assessment of an individual's fracture-risk that allow to take preventive action and give therapeutic advice. At present, bone-mineral-density (BMD) obtained from DXA (dual-energy x-ray-absorptiometry) is the clinical standard of reference for diagnosis and follow-up of osteoporosis. Since availability of DXA - other than that of clinical X-ray imaging - is usually restricted to specialized medical centers it is worth trying to implement alternative methods to estimate an individual's BMD. Radiographs of the peripheral skeleton, e.g. the ankle, range among the most ordered diagnostic procedures in surgery for exclusion or confirmation of fracture. It would be highly beneficial if - as a by-product of conventional imaging - one could obtain a quantitative parameter that is closely correlated with femoral BMD in addition to the original diagnostic information, e.g. fracture status at the peripheral site. Previous studies could demonstrate a correlation between calcaneal BMD and osteoporosis. The objective of our study was to test the hypothesis that topological analysis of calcaneal bone texture depicted by a lateral x-ray projection of the ankle allows to estimate femoral BMD. Our analysis on 34 post-menopausal patients indicate that texture properties based on graylevel topology in calcaneal x-ray-films are closely correlated with BMD at the hip and may qualify as a substitute indicator of femoral fracture risk.

  18. Pain and pain control in children.

    Focused research on pain and pain control in children has developed primarily in the last 10 years and even now is woefully inadequate in relation to the magnitude of the problem. The available research, inferences from the adult literature, and anecdotal information all indicate the elusive nature of pain. Pain is not solely a fixed neurophysiologic response to a noxious stimulus but a product of the interaction of many variables such as age, cognitive set, personality, ethnic background, and emotional state. These factors exert a tremendous influence on the suffering which surrounds the pain message. Technology exists at present to eliminate or substantially reduce pain in almost all cases. There remains, however, a tendency, which is even more pronounced with respect to children, to underestimate or ignore pain. In an overall approach to pain in children, the following points should be considered: A high index of suspicion is necessary to determine if children are experiencing pain since they may have difficulty verbalizing their discomfort. In infants, physiologic variables should be considered (increased heart rate, palmar sweating, increased respiratory rate), and in preschoolers, time should be taken to ascertain that the child actually understands the word "pain" if it is used in questioning them. Some method of continuous monitoring, such as a visual analogue scan, should be considered as part of the treatment plan. Adequate analgesia should be provided. The appropriate dose should be administered at the appropriate pharmacokinetic time. Too little medication may cause obsessive attention to medication-related issues. Too much medication may cause sedation and lack of mental clarity, which is often anxiety-producing for both the parents and the child. The usefulness of p.r.n. medication has been seriously questioned and a time-contingent as opposed to pain-contingent strategy should be applied. Fears of addiction are generally unwarranted. Adjunctive medication may increase the value of offered narcotics and counteract some of their side effects. Although this monograph has focused more attention on pharmacologic than on nonpharmacologic approaches to pain, this is merely a reflection of available data and not necessarily of relative importance. The importance of distraction from pain by nursing, medical, or child life personnel using play techniques cannot be overestimated. Every attempt should be made to relax the child by using creative strategies. Preparation of the child for procedures is often helpful as some of the fear of the unknown is eliminated.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:2861066

    During sluicing operations of tank 241-C-110, a significant amount of solids were unable to be retrieved. These solids (often referred to as the tank 'heel') were sampled in 2010 and chemically and mineralogically analyzed in the 222-S Laboratory. Additionally, dissolution tests were performed to identify the amount of undissolvable material after using multiple water contacts. This report covers the solid phase characterization of six samples from these tests using scanning electron microscopy, polarized light microscopy, and X-ray diffraction. The chemical analyses, particle size distribution analysis, and dissolution test results are reported separately. Two of the samples were from composites created from as-received material - Composite A and Composite B. The main phase in these samples was sodium-fluoride-phosphate hydrate (natrophosphate) - in the X-ray diffraction spectra, this phase was the only phase identifiable. Polarized light microscopy showed the presence of minor amounts of gibbsite and other phases. These phases were identified by scanning electron microscopy - energy dispersive X-ray spectroscopy as sodium aluminosilicates, sodium diuranate, and sodium strontium phosphate hydrate (nastrophite) crystals. The natrophosphate crystals in the scanning electron microscopy analysis showed a variety of erosive and dissolution features from perfectly shaped octahedral to well-rounded appearance. Two samples were from water-washed Composites A and B, with no change in mineralogy compared to the as-received samples. This is not surprising, since the water wash had only a short period of water contact with the material as opposed to the water dissolution tests. The last two samples were residual solids from the water dissolution tests. These tests included multiple additions of water at 15 C and 45 C. The samples were sieved to separate a coarser fraction of > 710 {mu}m and a finer fraction of < 710 {mu}m. These two fractions were analyzed separately. The coarser fraction contained mostly gibbsite with minor amounts of sodium aluminosilicates (cancrinite) and bismuth aluminum-rich phases. The finer fraction was mostly composed of gibbsite, the sodium alumino silicate phase, cancrinite, and a poorly crystalline to non-crystalline phase containing varying amounts of iron, bismuth, aluminum, and phosphorus.

    SUMMARY Considerable evidence demonstrates substantial ethnic disparities in the prevalence, treatment, progression and outcomes of pain-related conditions. Elucidating the mechanisms underlying these group differences is of crucial importance in reducing and eliminating disparities in the pain experience. Over recent years, accumulating evidence has identified a variety of processes, from neurophysiological factors to structural elements of the healthcare system, that may contribute to shaping individual differences in pain. For example, the experience of pain differentially activates stress-related physiological responses across various ethnic groups, members of different ethnic groups appear to use differing coping strategies in managing pain complaints, providers’ treatment decisions vary as a function of patient ethnicity and pharmacies in predominantly minority neighborhoods are far less likely to stock potent analgesics. These diverse factors, and others may all play a role in facilitating elevated levels of pain-related suffering among individuals from ethnic minority backgrounds. Here, we present a brief, nonexhaustive review of the recent literature and potential physiological and sociocultural mechanisms underlying these ethnic group disparities in pain outcomes.

    Few studies address chronic disease risk for Southeast Asians in the United States. In 1999, the authors conducted a cross-sectional study of bone mineral density (BMD) estimated from ultrasonic calcaneal measurements in women born in Southeast Asia who then lived in Chicago, Illinois. The study addressed three questions: Do Southeast-Asian women have relatively low BMD? What factors before and after immigration are associated with BMD? Are factors that reflect the childhood/adolescent environment equally associated with BMD for postmenopausal and premenopausal women? An interviewer-administered bilingual questionnaire collected immigration, reproductive, and lifestyle data from 213 women (aged 20--80 years) born in Vietnam, Cambodia, or Laos. The authors found that the estimated mean BMD of postmenopausal Southeast-Asian women was lower than the reference values for White women. Four summary indicators of childhood/adolescent environment were predictive of higher BMD: more years of education, earlier age at menarche, lower height, and coastal birth; these indicators were more strongly associated with BMD for premenopausal (multiple-partial R(2) = 0.21) than postmenopausal (R(2) = 0.06) women. Young-adult exposures (e.g., early first pregnancy and age at immigration) and proximal lifestyle factors (e.g., smoking, physical inactivity, vegetarian diet, and betel nut use) were also assessed as potential predictors of BMD.

    Deafferentation, like as in limb amputation, brachial plexus avulsion injury and spinal cord injury, is usually followed by neuropathic pain. Neuropathic pain is a debilitating condition and it impairs the quality of life profoundly. Based on recent advances in the cognitive neuroscience, we explain intimate relationships among neuropathic pain, reorganization of primary sensory and motor cortices and the sensorimotor integration of the deafferentated limb. From the standpoint of the sensorimotor integration theory for emerging phantom limb pain, we further discuss the analgesic mechanism of neurorehabilitation techniques such as mirror visual feedback treatment and its related neurorobotics advancement for neuropathic pain.

    Quantitative ultrasound (QUS) of the heel and tibia have recently been approved in the United States for diagnostic evaluation of low bone mass. The goal of this study was to use human cadaveric specimens to compare correlations among: a) strength of the proximal femur; b) bone mineral density of the femur, tibia, and heel; and c) QUS of the tibia and heel. We obtained 26 proximal femurs and intact lower limbs from 16 female and 10 male cadavers, with a mean age of 81+/-12 years. Bone mineral density (BMD, g/cm2) of the proximal femur and tibia were assessed using dual-energy x-ray absorptiometry, and BMD (g/cm) of the heel was measured using single-energy x-ray absorptiometry. Ultrasound velocity at the mid-tibia was determined using a contact, gel-coupled ultrasound device. Broadband ultrasound attenuation (BUA) and speed of sound (SOS) of the heel were determined using a transmission ultrasound device with water-based coupling. The femurs were tested to failure in a configuration designed to simulate a fall to the side with impact to the greater trochanter. As in previous studies, the strength of the proximal femur was very strongly correlated with femoral BMD and heel BMD (r2 = 0.78-0.92, p < .0001 for all). BUA and SOS of the heel were also strongly correlated to femoral strength (r2 = 0.70 and 0.67, respectively, p < 0.0001 for both), whereas tibia SOS was only weakly correlated (r2 = 0.19, p = 0.03). The average coefficient of variation for triplicate tibial SOS measurements was 0.50%. This study indicates that, although tibial SOS measurements are precise, they are not strongly correlated with femoral BMD or strength. In contrast, heel QUS measurements are strongly correlated with the strength of the proximal femur. These findings imply that tibial SOS may be of limited use for assessing hip fracture risk. Prospective fracture risk data are needed to define further the clinical utility of tibia ultrasound measurements. PMID:10423021

    Background Postural control during rapid movements may be impaired due to musculoskeletal pain. The purpose of this study was to investigate the effect of experimental knee-related muscle pain on the center of pressure (CoP) displacement in a reaction time task condition. Methods Nine healthy males performed two reaction time tasks (dominant side shoulder flexion and bilateral heel lift) before, during, and after experimental pain induced in the dominant side vastus medialis or the tibialis anterior muscles by hypertonic saline injections. The CoP displacement was extracted from the ipsilateral and contralateral side by two force plates and the net CoP displacement was calculated. Results Compared with non-painful sessions, tibialis anterior muscle pain during the peak and peak-to-peak displacement for the CoP during anticipatory postural adjustments (APAs) of the shoulder task reduced the peak-to-peak displacement of the net CoP in the medial-lateral direction (P<0.05). Tibialis anterior and vastus medialis muscle pain during shoulder flexion task reduced the anterior-posterior peak-to-peak displacement in the ipsilateral side (P<0.05). Conclusions The central nervous system in healthy individuals was sufficiently robust in maintaining the APA characteristics during pain, although the displacement of net and ipsilateral CoP in the medial-lateral and anterior-posterior directions during unilateral fast shoulder movement was altered.

    Our understanding of the immediate effects of exercise on Achilles free tendon transverse morphology is limited to single site measurements acquired at rest using 2D ultrasound. The purpose of this study was to provide a detailed 3D description of changes in Achilles free tendon morphology immediately following a single clinical bout of exercise. Freehand 3D ultrasound was used to measure Achilles free tendon length, and regional cross-sectional area (CSA), medio-lateral (ML) diameter and antero-posterior (AP) diameter in healthy young adults (N=14) at rest and during isometric muscle contraction, immediately before and after 3×15 eccentric heel drops. Post-exercise reductions in transverse strain were limited to CSA and AP diameter in the mid-proximal region of the Achilles free tendon during muscle contraction. The change in CSA strain during muscle contraction was significantly correlated to the change in longitudinal strain (r=-0.72) and the change in AP diameter strain (r=0.64). Overall findings suggest the Achilles free tendon experiences a complex change in 3D morphology following eccentric heel drop exercise that manifests under contractile but not rest conditions, is most pronounced in the mid-proximal tendon and is primarily driven by changes in AP diameter strain and not ML diameter strain.

    Footwear has been implicated as a factor in falls, which is a major issue affecting the health of older adults. This study investigated the effect of footwear with dorsal fixation, slippers and bare feet on minimum foot clearance, heel slippage and spatiotemporal variables of gait in community dwelling older women. Thirty women participated (mean age (SD) 69.1 (5.1) years) in a gait assessment using the GaitRITE and Vicon 612 motion analysis system. Conditions included footwear with dorsal fixation, slippers or bare feet. Footwear with dorsal fixation resulted in improved minimum foot clearance compared to the slippers and bare feet conditions and less heel slippage than slippers and an increase in double support. These features lend weight to the argument that older women should be supported to make footwear choices with optimal fitting features including dorsal fixation. Recommendations of particular styles and features of footwear may assist during falls prevention education to reduce the incidence of foot trips and falls. PMID:27004631

  8. [Pathophysiology of abdominal pain].

    PubMed

    Curatolo, Michele

    2011-08-01

    Abdominal pain can be induced by stimulation of visceral nociceptors. Activation of nociceptors usually requires previous sensitization by pathological events, such as inflammation, ischemia or acidosis. Although abdominal pain can obviously be caused by pathology of a visceral structure, clinicians frequently observe that such a pathology explains only part of the pain complaints. Occasionally, there is lack of objective signs of visceral lesions. There is clear evidence that pain states are associated with profound changes of the central processing of the sensory input. The main consequences of such alterations for patients are twofold: 1) a central sensitization, i.e. an increased excitability of the central nervous system; 2) an alteration of the endogenous pain modulation, which under normal conditions inhibits the processing of nociceptive signals in the central nervous system. Both phenomena lead to a spread of pain to other body regions and an amplification of the pain perception. The interactions between visceral pathology and alterations of the central pain processes represent an at least partial explanation for the discrepancy between objective signs of peripheral lesions and severity of the symptoms. Today, both central hypersensitivity and alteration in endogenous pain modulation can be measured in clinical practice. This information can be used to provide the patients with an explanatory model for their pain. Furthermore, first data suggest that alterations in central pain processing may represent negative prognostic factors. A better understanding of the individual pathophysiology may allow in the future the development of individual therapeutic strategies. PMID:21796591

    Chronic postoperative pain is common. Nerve injury and inflammation promote chronic pain, the risk of which is influenced by patient factors, including psychological characteristics. Interventional trials to prevent chronic postoperative pain have been underpowered with inadequate patient follow-up. Ketamine may reduce chronic postoperative pain, although the optimum treatment duration and dose for different operations have yet to be identified. The evidence for gabapentin and pregabalin is encouraging but weak; further work is needed before these drugs can be recommended for the prevention of chronic pain. Regional techniques reduce the rates of chronic pain after thoracotomy and breast cancer surgery. Nerve-sparing surgical techniques may be of benefit, although nerve injury is not necessary or sufficient for chronic pain to develop. PMID:26620149

    Pain in infancy and childhood is extremely common. Sources of pain include illness, injury, and medical and dental procedures. Over the past two decades, tremendous progress has been made in the assessment, prevention and treatment of pain. It is important for the paediatric health care provider to be aware of the implications and consequences of pain in childhood. A multitude of interventions are available to reduce or alleviate pain in children of all ages, including neonates. These include behavioural and psychological methods, as well as a host of pharmacological preparations, which are safe and effective when used as indicated. Many complementary and alternative treatments appear to be promising in treating and relieving pain, although further research is required. The present article reviews the most common sources of pain in childhood and infancy, as well as current treatment strategies and options. PMID:19030348

    Labour is an emotional experience and involves both physiological and psychological mechanisms. The pain of labour is severe but despite this its memory diminishes with time. Labour pain has two components: visceral pain which occurs during the early first stage and the second stage of childbirth, and somatic pain which occurs during the late first stage and the second stage. The pain of labour in the first stage is mediated by T10 to L1 spinal segments, whereas that in the second stage is carried by T12 to L1, and S2 to S4 spinal segments. Pain relief in labour is complex and often challenging without regional analgesia. Effective management of labour pain plays a relatively minor role in a woman's satisfaction with childbirth.

    The objective of this longitudinal study, conducted in a neonatal intensive care unit, was to characterize the response to pain of high-risk very low birth weight infants (<1,500 g) from 23 to 38 weeks post-menstrual age (PMA) by measuring heart rate variability (HRV). Heart period data were recorded before, during, and after a heel lanced or wrist venipunctured blood draw for routine clinical evaluation. Pain response to the blood draw procedure and age-related changes of HRV in low-frequency and high-frequency bands were modeled with linear mixed-effects models. HRV in both bands decreased during pain, followed by a recovery to near-baseline levels. Venipuncture and mechanical ventilation were factors that attenuated the HRV response to pain. HRV at the baseline increased with post-menstrual age but the growth rate of high-frequency power was reduced in mechanically ventilated infants. There was some evidence that low-frequency HRV response to pain improved with advancing PMA. PMID:19739134

    Objective The objective of this study was to investigate the existence of an equine pain face and to describe this in detail. Study design Semi-randomized, controlled, crossover trial. Animals Six adult horses. Methods Pain was induced with two noxious stimuli, a tourniquet on the antebrachium and topical application of capsaicin. All horses participated in two control trials and received both noxious stimuli twice, once with and once without an observer present. During all sessions their pain state was scored. The horses were filmed and the close-up video recordings of the faces were analysed for alterations in behaviour and facial expressions. Still images from the trials were evaluated for the presence of each of the specific pain face features identified from the video analysis. Results Both noxious challenges were effective in producing a pain response resulting in significantly increased pain scores. Alterations in facial expressions were observed in all horses during all noxious stimulations. The number of pain face features present on the still images from the noxious challenges were significantly higher than for the control trial (p = 0.0001). Facial expressions representative for control and pain trials were condensed into explanatory illustrations. During pain sessions with an observer present, the horses increased their contact-seeking behavior. Conclusions and clinical relevance An equine pain face comprising ‘low’ and/or ‘asymmetrical’ ears, an angled appearance of the eyes, a withdrawn and/or tense stare, mediolaterally dilated nostrils and tension of the lips, chin and certain facial muscles can be recognized in horses during induced acute pain. This description of an equine pain face may be useful for improving tools for pain recognition in horses with mild to moderate pain. PMID:25082060

The subjects were 13 sufferers of musculoskeletal pain and 17 non-sufferers. Pain diary and pain chart systems were used for the measurement of menstrual pain-related factors and musculoskeletal pain. Data were analyzed using repeated ANOVA. The results show that there are significant differences between the two groups in pain level, activity, and mood during menstruation periods (P< 0.05).

    Foreman, Robert D; Garrett, Kennon M; Blair, Robert W

    2015-04-01

    Angina pectoris is cardiac pain that typically is manifested as referred pain to the chest and upper left arm. Atypical pain to describe localization of the perception, generally experienced more by women, is referred to the back, neck, and/or jaw. This article summarizes the neurophysiological and pharmacological mechanisms for referred cardiac pain. Spinal cardiac afferent fibers mediate typical anginal pain via pathways from the spinal cord to the thalamus and ultimately cerebral cortex. Spinal neurotransmission involves substance P, glutamate, and transient receptor potential vanilloid-1 (TRPV1) receptors; release of neurokinins such as nuclear factor kappa b (NF-kb) in the spinal cord can modulate neurotransmission. Vagal cardiac afferent fibers likely mediate atypical anginal pain and contribute to cardiac ischemia without accompanying pain via relays through the nucleus of the solitary tract and the C1-C2 spinal segments. The psychological state of an individual can modulate cardiac nociception via pathways involving the amygdala. Descending pathways originating from nucleus raphe magnus and the pons also can modulate cardiac nociception. Sensory input from other visceral organs can mimic cardiac pain due to convergence of this input with cardiac input onto spinothalamic tract neurons. Reduction of converging nociceptive input from the gallbladder and gastrointestinal tract can diminish cardiac pain. Much work remains to be performed to discern the interactions among complex neural pathways that ultimately produce or do not produce the sensations associated with cardiac pain. PMID:25880519

    Phantom pain is pain caused by elimination or interruption of sensory nerve impulses by destroying or injuring the sensory nerve fibers after amputation or deafferentation. The reported incidence of phantom limb pain after trauma, injury or peripheral vascular diseases is 60% to 80%. Over half the patients with phantom pain have stump pain as well. Phantom pain can also occur in other parts of the body; it has been described after mastectomies and enucleation of the eye. Most patients with phantom pain have intermittent pain, with intervals that range from 1 day to several weeks. Even intervals of over a year have been reported. The pain often presents itself in the form of attacks that vary in duration from a few seconds to minutes or hours. In most cases, the pain is experienced distally in the missing limb, in places with the most extensive innervation density and cortical representation. Although there are still many questions as to the underlying mechanisms, peripheral as well as central neuronal mechanisms seem to be involved. Conservative therapy consists of drug treatment with amitriptyline, tramadol, carbamazepine, ketamine, or morphine. Based on the available evidence some effect may be expected from drug treatment. When conservative treatment fails, pulsed radiofrequency treatment of the stump neuroma or of the spinal ganglion (DRG) or spinal cord stimulation could be considered (evidence score 0). These treatments should only be applied in a study design. PMID:21447079

    Effective pain management is a desirable standard of care for preterm and term newborns and may potentially improve their clinical and neurodevelopmental outcomes. Neonatal pain should be assessed routinely using context-specific, validated and objective pain methods, despite the limitations of currently available tools. Reducing invasive procedures, and using pharmacological, behavioral or environmental measures can be used to manage neonatal pain. Non-pharmacologic approaches include kangaroo care, facilitated tucking, non-nutritive sucking, sucrose and other sweeteners, massage and acupuncture therapy. They are used for procedures causing acute, transient, or mild pain, or as adjunctive therapy for moderate or severe pain. Local and topical anesthetics can reduce the acute pain caused by skin-breaking or mucosa-injuring procedures. Opioids form the mainstay for treatment of severe pain; morphine and fentanyl are the most commonly used drugs, although other opioids are also available. Non-opioid drugs include various sedatives and anesthetic agents, mostly used as adjunctive therapy in ventilated neonates. Acetaminophen, ibuprofen and other drugs are used for neonates, although their efficacy and safety remains unproven. Approaches for implementing an effective pain management program in the Neonatal ICU are summarized, together with practical protocols for procedural, postoperative, and mechanical ventilation-associated neonatal pain and stress.

    Pain and other nonmotor symptoms in PD are increasingly recognized as a major cause of reduced health-related quality of life. Pain in PD may be categorized into a number of different subtypes, including musculoskeletal, dystonic, radicular neuropathic, and central pain. The onset of pain can vary in relation to motor symptoms, and may precede the appearance of motor symptoms by several years, or occur after the diagnosis of PD has been made. Pain in PD is frequently under-recognized and is often inadequately treated. Levodopa-related dystonia may respond to manipulation of dopaminergic medication. Dopaminergic therapy may also improve musculoskeletal pain related to rigidity and akinesia, as well as akathisia in PD. Botulinum toxin injections can be effective for treatment of painful focal dystonia. Pain and dysesthesia have been reported to improve with DBS, in some cases. Increased understanding of basal ganglia pathways has provided further insights into the pathogenesis of pain in PD, but the exact mechanism of pain processing and modulation remains unclear.

    Pain is a common problem in cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain that interferes with functioning. The prevalence is much higher in certain subpopulations, such as breast cancer survivors. All cancer treatment modalities have the potential to cause pain. Currently, the approach to managing pain in cancer survivors is similar to that for chronic cancer-related pain, pharmacotherapy being the principal treatment modality. Although it may be appropriate to continue strong opioids in survivors with moderate to severe pain, most pain problems in cancer survivors will not require them. Moreover, because more than 40% of cancer survivors now live longer than 10 years, there is growing concern about the long-term adverse effects of opioids and the risks of misuse, abuse, and overdose in the nonpatient population. As with chronic nonmalignant pain, multimodal interventions that incorporate nonpharmacologic therapies should be part of the treatment strategy for pain in cancer survivors, prescribed with the aim of restoring functionality, not just providing comfort. For patients with complex pain issues, multidisciplinary programs should be used, if available. New or worsening pain in a cancer survivor must be evaluated to determine whether the cause is recurrent disease or a second malignancy. This article focuses on patients with a history of cancer who are beyond the acute diagnosis and treatment phase and on common treatment-related pain etiologies. The benefits and harms of the various pharmacologic and nonpharmacologic options for pain management in this setting are reviewed. PMID:24799477

    Pain is a common problem in cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain that interferes with functioning. The prevalence is much higher in certain subpopulations, such as breast cancer survivors. All cancer treatment modalities have the potential to cause pain. Currently, the approach to managing pain in cancer survivors is similar to that for chronic cancer-related pain, pharmacotherapy being the principal treatment modality. Although it may be appropriate to continue strong opioids in survivors with moderate to severe pain, most pain problems in cancer survivors will not require them. Moreover, because more than 40% of cancer survivors now live longer than 10 years, there is growing concern about the long-term adverse effects of opioids and the risks of misuse, abuse, and overdose in the nonpatient population. As with chronic nonmalignant pain, multimodal interventions that incorporate nonpharmacologic therapies should be part of the treatment strategy for pain in cancer survivors, prescribed with the aim of restoring functionality, not just providing comfort. For patients with complex pain issues, multidisciplinary programs should be used, if available. New or worsening pain in a cancer survivor must be evaluated to determine whether the cause is recurrent disease or a second malignancy. This article focuses on patients with a history of cancer who are beyond the acute diagnosis and treatment phase and on common treatment-related pain etiologies. The benefits and harms of the various pharmacologic and nonpharmacologic options for pain management in this setting are reviewed. PMID:24799477

  2. Neurological diseases and pain

    PubMed Central

    2012-01-01

    Chronic pain is a frequent component of many neurological disorders, affecting 20–40% of patients for many primary neurological diseases. These diseases result from a wide range of pathophysiologies including traumatic injury to the central nervous system, neurodegeneration and neuroinflammation, and exploring the aetiology of pain in these disorders is an opportunity to achieve new insight into pain processing. Whether pain originates in the central or peripheral nervous system, it frequently becomes centralized through maladaptive responses within the central nervous system that can profoundly alter brain systems and thereby behaviour (e.g. depression). Chronic pain should thus be considered a brain disease in which alterations in neural networks affect multiple aspects of brain function, structure and chemistry. The study and treatment of this disease is greatly complicated by the lack of objective measures for either the symptoms or the underlying mechanisms of chronic pain. In pain associated with neurological disease, it is sometimes difficult to obtain even a subjective evaluation of pain, as is the case for patients in a vegetative state or end-stage Alzheimer's disease. It is critical that neurologists become more involved in chronic pain treatment and research (already significant in the fields of migraine and peripheral neuropathies). To achieve this goal, greater efforts are needed to enhance training for neurologists in pain treatment and promote greater interest in the field. This review describes examples of pain in different neurological diseases including primary neurological pain conditions, discusses the therapeutic potential of brain-targeted therapies and highlights the need for objective measures of pain.

    The aim of this experimental study was to investigate the effects of low-intensity light-emitting diode (LED) phototherapy on the inflammatory process in the calcaneal tendon of ovariectomized rats (OVX) through the involvement of the inflammatory mediators interleukin (IL)-6, IL-10, and tumor necrosis factor-alpha (TNF-α). Thirty-five female Wistar rats were divided into 4 groups: 3 groups of OVX rats totaling 30 rats (untreated OVX rats [OVX injury group], treated OVX rats [OVX LED group], and control OVX rats; subgroups existed based on the sampling times, which were 3, 7, and 14 days) and 1 group of non-OVX rats (not OVX; n = 5). Tendon injury was induced by trauma using a 208-g mass placed at 20 cm from the right tendon of each animal with energy of 0.70 J. The animals were treated 12 h after tendonitis with LED therapy and every 48 h thereafter until euthanasia (at 3, 7, or 14 days). The tendons were dissected and stored in liquid nitrogen at -196 °C, thawed only at the time of immunoenzymatic testing (ELISA). Groups treated with LED showed a decrease in the number of pro-inflammatory cells, IL-6, and TNF-α (p <0.05), and an increase in IL-10 (p < 0.05) when compared to the not OVX group (p < 0.05). It was concluded that low-intensity LED treatment using the parameters and wavelength of 945 nm in the time periods studied reduced the release of IL-6 and TNF-α and increased the release of IL-10, thereby improving the inflammatory response in OVX rats.

    A viscoelastic model of the K-BKZ (Kaye, Technical Report 134, College of Aeronautics, Cranfield 1962; Bernstein et al., Trans Soc Rheol 7: 391-410, 1963) type is developed for isotropic biological tissues and applied to the fat pad of the human heel. To facilitate this pursuit, a class of elastic solids is introduced through a novel strain-energy function whose elements possess strong ellipticity, and therefore lead to stable material models. This elastic potential - via the K-BKZ hypothesis - also produces the tensorial structure of the viscoelastic model. Candidate sets of functions are proposed for the elastic and viscoelastic material functions present in the model, including two functions whose origins lie in the fractional calculus. The Akaike information criterion is used to perform multi-model inference, enabling an objective selection to be made as to the best material function from within a candidate set. PMID:16575573

  5. Amphibian pain and analgesia.

    Analgesics are often not provided to amphibians because the presence and severity of pain may not be recognized in these animals. In addition, there is little information on the mechanism of action of analgesic agents in amphibians. However, amphibians possess appropriate neurologic components for transmitting pain from peripheral receptors to the central nervous system and antinociceptive mechanisms to modulate pain. They are capable of displaying behavioral and physiologic modification of pain systems in response to analgesic pharmacologic agents. Therefore, pain perception in amphibians is likely analogous to that in mammals and invasive, potentially painful procedures should be accompanied by appropriate analgesia and anesthesia. Although specific doses have not been established in clinical trials, basic research into the mechanisms and regulation of endogenous opioid systems demonstrates the potential clinical benefit for the use of opioids in these animals. Other analgesics such as alpha2-agonists, ketamine, and tricaine methanesulfonate have also demonstrated analgesic potential. PMID:10367638

    To determine frequency of neuromusculoskeletal etiology of chest pain is performed. By means of a retrospective analysis and on the basis of the history of the patients' disease, data were collected after chest pain had been medically worked out. The causes to chest pain were in 82% of cardial etiology, in 9% of neuromusculoskeletal etiology, in 6% of gastrointestinal etiology and 3% others. All the patients suffering from neuromusculoskeletal causes to chest pain were, besides anti-rheumatic therapy, also treated by certain form of cardiac therapy. The task of a doctor is to accurately recognize serious disorders as possible causes to chest pain. However, the doctor must not make wrong diagnosis of potentially dangerous conditions thus causing unwanted psychological and economical consequences. In order to realize this, adequate diagnostic possibilities are necessary besides the knowledge about all possible causes to chest pain. PMID:15067819

    Pain is a complex problem, for both those who are enduring it and those trying to relieve it. Most people in the developed world have access to adequate treatment and management of pain, the availability of trained and educated doctors and nurses, feasible opioid prescribing policies, as well as ready access to appropriate medication. Often, this is not the case in developing countries such as Thailand. This paper is based on recent experience in the southeast of Thailand providing pain relief for persons with HIV and AIDS in Rayong Province at the Camillian Social Centre. The severity and frequency of pain endured by this group of individuals presented a daily challenge. Problems encountered in providing pain relief for these patients and some potential solutions are described. There is a lack of literature on pain relief in Thailand. PMID:15022951

    The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    As a standard of care for preterm/term newborns effective pain management may improve their clinical and neurodevelopmental outcomes. Neonatal pain is assessed using context-specific, validated, and objective pain methods, despite the limitations of currently available tools. Therapeutic approaches reducing invasive procedures and using pharmacologic, behavioral, or environmental measures are used to manage neonatal pain. Nonpharmacologic approaches like kangaroo care, facilitated tucking, non-nutritive sucking, sucrose, and others can be used for procedural pain or adjunctive therapy. Local/topical anesthetics, opioids, NSAIDs/acetaminophen and other sedative/anesthetic agents can be incorporated into NICU protocols for managing moderate/severe pain or distress in all newborns.

    Background. Currently, free flaps and pedicled flaps are the first treatment choices for large heel ulcer reconstruction. However, flap reconstruction of heel ulcerations cannot be performed in all diabetics especially with concurrent severe peripheral vascular disease because of higher flap failure rate. In recent years, the use of acellular dermal matrix (ADM) has emerged as an alternative treatment option for extremity ulcers. Methods. We present 13 diabetic patients with a large heel ulceration exposing the calcaneus, who were not eligible for flap surgery due to the presence of only one patent artery of trifurcation. These cases were treated with the vacuum assisted sandwich dermal matrix (VASDEM) method. Results. None of the patients required amputation. Skin grafting was successful in ten patients. Although partial losses were observed in three patients, they were healed spontaneously without surgical interventions. During the follow-up period none of the patients developed ulceration on the treatment area. All patients maintained their preoperative ambulatory ability. Conclusion. VASDEM is a novel method offering opportunity for treatment before proceeding to amputation in diabetic heel ulceration exposing the calcaneus which is not suitable for flap surgery. It also has the potential to close wounds of all sizes independent of the vessel status and wound size in selected diabetic patients. PMID:26516626

    The medial crural fasciocutaneous flap is a reliable cutaneous flap that can be used for soft tissue reconstruction in the extremities. The purpose of this article is to evaluate the application and clinical significance of this surgical technique in the reconstruction of heel soft tissue defects. Twenty-one cases of heel soft tissue defect between March 2005 and March 2012 were included in this study. Wound sizes varied from 5.0 × 5.5 to 7.5 × 10.0 cm. All cases were managed with a reverse medial crural fasciocutaneous flap. Patient demographics and case information were analyzed and are reported. The sizes of the reverse medial crural fasciocutaneous flap varied from 6.5 × 10.0 to 9.0 × 15.0 cm; the average size was 7.7 × 13.8 cm. Out of the 21 consecutive cases, 20 flaps survived intact and one flap underwent partial necrosis. Follow-up observations were conducted for 6-36 months. The cosmetic results were satisfactory, without apparent bulkiness; the weight-bearing outcomes were satisfactory. The donor site can be closed primarily or by skin graft. Reverse medial crural fasciocutaneous flap transfer is appropriate for the reconstruction of heel soft tissue defects. The method is safe and can cover large heel defects. PMID:25448373

    In this paper, we propose an advanced pedestrian dead-reckoning (PDR) algorithm that considers the heel-strike and toe-off phases. Generally, PDR systems that use a foot-mounted inertial measurement unit are based on an inertial navigation system with an extended Kalman filter (EKF). To reduce the influence of the bias and white noises in the gyroscope and accelerometer signals, a zero-velocity update is often adopted at the stance phase. However, transient and large acceleration, which cannot be measured by the accelerometer used in pedestrian navigation, occur momentarily in the heel-strike phase. The velocity information from integration of the acceleration is not reliable because the acceleration is not measured in the heel-strike phase. Therefore, the designed EKF does not correctly reflect the actual environment, because conventional algorithms do not take the non-measurable acceleration into consideration. In order to reflect the actual environment, we propose a PDR system that considers the non-measurable acceleration from the heel-strike impact. To improve the PDR system’s performance, the proposed algorithm uses a new velocity measurement obtained using the constraint between the surface and the foot during the toe-off phase. The experimental results show improved filter performance after comparison of the proposed algorithm and a conventional algorithm.

  13. Painful Peripheral Neuropathies

    2006-01-01

    Peripheral neuropathies are a heterogeneous group of diseases affecting peripheral nerves. The causes are multiple: hereditary, metabolic, infectious, inflammatory, toxic, traumatic. The temporal profile includes acute, subacute and chronic conditions. The majority of peripheral neuropathies cause mainly muscle weakness and sensory loss, positive sensory symptoms and sometimes pain. When pain is present, however, it is usually extremely intense and among the most disabling symptoms for the patients. In addition, the neurological origin of the pain is often missed and patients receive inadequate or delayed specific treatment. Independently of the disease causing the peripheral nerve injury, pain originating from axonal pathology or ganglionopathy privileges neuropathies affecting smaller fibres, a clinical observation that points towards abnormal activity within nociceptive afferents as a main generator of pain. Natural activation of blood vessels or perineurial nociceptive network by pathology also causes intense pain. Pain of this kind, i.e. nerve trunk pain, is among the heralding symptoms of inflammatory or ischemic mononeuropathy and for its intensity represents itself a medical emergency. Neuropathic pain quality rekindles the psychophysical experience of peripheral nerves intraneural microstimulation i.e. a combination of large and small fibres sensation temporally distorted compared to physiological perception evoked by natural stimuli. Pins and needles, burning, cramping mixed with numbness, and tingling are the wording most used by patients. Nociceptive pain instead is most often described as aching, deep and dull. Good command of peripheral nerve anatomy and pathophysiology allows timely recognition of the different pain components and targeted treatment, selected according to intensity, type and temporal profile of the pain.

    2015-01-01

    Low-back pain is one of the most common painful conditions experienced by humans throughout their life. Some occupational risk factors (namely, heavy manual material handling) may also contribute to the development of low-back pain: due to the high prevalence of both low-back pain and manual material handling in the adult working population, it has been estimated that low-back pain is probably the most common occupational disorder worldwide. Lifetime prevalence of low-back pain has been reported to be as high as 84%, depending on the case definition used, and no age group is spared, even children. Although low-back pain is not a lethal condition, it was estimated at the third rank among all diseases by disability-adjusted life-years in 2010 in the USA, after ischemic heart disease and chronic obstructive pulmonary disease, and at the first rank by years lived with disability. It also ranked high (13th) globally for the same year, in disability-adjusted life-years. Low-back pain is currently classified as nonspecific/specific as to putative cause and as acute (lasting less than 6 weeks), subacute (6-12 weeks), or chronic (more than 12 weeks) according to duration of symptoms. The distinction between nonspecific/specific and acute/subacute/chronic low-back pain is useful not only for epidemiologic studies, but also (mainly) for choosing the appropriate strategy for the diagnosis and treatment of the disorder. Workplace risk factors for low-back pain include manual lifting and whole-body vibration exposure. This chapter will provide an overview of modern concepts of low-back pain (in general) and will then outline some distinctive features of work-related low-back pain. PMID:26563799

    The experience of pain is related not only to tissue damage and physical illness, but also to mental phenomena including depression, anxiety and somatization. Somatization is common among chronic pain patients and presents special problems in management and treatment. Somatoform patients are often given inappropriate diagnoses, treated for non-existent depressive disorders, and exposed to multiple, superfluous investigations. Psychological models of chronic pain and somatization are presented, and treatment issues including psychotherapy and the use of antidepressants are discussed. PMID:11683662

  17. Computer Modeling Studies to Assess Whether a Prophylactic Dressing Reduces the Risk for Deep Tissue Injury in the Heels of Supine Patients with Diabetes.

    Heels are susceptible to pressure ulcer (PU) development. Some evidence suggests dressings may provide mechanical cushioning, reduce friction with support, and lower localized internal tissue loading, which together may minimize the risk for heel ulcers (HUs). To examine the effect of dressing application on pressure ulcer prevention, 20 computer simulations were performed. Volumetric exposure of soft tissues to effective and shear strains and stresses, with and without a multilayered foam dressing, were assessed, with the extent of tissue exposure considered as measures of the theoretical risk for PUs. The simulations, conducted using the finite element method, provided the mechanical strain and stress magnitudes and distributions in the weight-bearing tissues of the heel, which were visualized and analyzed post-hoc for comparing diabetic to healthy tissue loads with/without prophylactic dressings and at different foot (plantar flexion) postures. The volumetric exposure of the soft tissues of the heel to elevated strains and stresses was considerably reduced by the presence of the dressing, whether diabetic or nondiabetic tissue conditions existed, and for the entire range of the simulated plantar flexion positions. Further, greater plantar flexion, which occurs with elevation of the head of the bed, reduced the volumetric exposure of subcutaneous fat to increased effective strains and stresses, again, particularly when the dressing was on. Specifically, peak (maximum of raw data) effective strains in the soft tissues of the heel decreased by 14.8% and 13.5% with the use of the dressing for healthy persons and persons with diabetes, respectively. Additionally, volumetric exposures of the soft tissues to large effective strains, defined as exposures to >50% strain, decreased substantially, by at least a factor of 2, with the angle of plantar flexion and with respect to a neutral foot posture. Volumetric exposures to midrange (less than 50%) strains were more mildly affected by the foot posture (ie, less than 10% difference was noted across plantar flexion angles). The differences in tissue exposures to strains and stresses between the dressing and nondressing models suggest this dressing provides an important biomechanical protective effect, specifically when diabetic tissue conditions exist. In addition, the data suggest alleviating shear by repositioning the heels after elevating the head of the bed may be critical in order to limit the increase in tissue stress and subsequent PU risk. Randomized, controlled clinical studies to examine the efficacy of dressings for the prevention of heel PUs are warranted. PMID:27065218

    Pain disorders present highly challenging therapeutic problems, owing in part to complex co-morbidities associated with pain disorders, notably including psychiatric disorders characterized by depressed mood or anxiety. Many treatments are employed to treat pain-disorder patients, and most are unsatisfactory. Virtually all analgesic medicines in long-term use provide only partial efficacy and present substantial risks of adverse effects, loss of benefit over time, or dependency and risk of abuse. Commonly employed drugs with analgesic properties include non-opioids (mainly nonsteroidal anti-inflammatory agents [NSAIDs] or acetaminophen), many natural or synthetic opioids (including opiates and phenylpiperidines), some antidepressants (especially those with noradrenergic activity), a few anticonvulsants, skeletal muscle relaxants or topical remedies, and a growing variety of experimental treatments. The major overlap between pain and psychiatric disorders, as well as the currently unsatisfactory state of treatments available for chronic pain syndromes, encourage a comprehensive approach to assessment and clinical management of patients with chronic pain. Many current treatment programs for pain disorder patients offer narrowly specialized and incomplete treatment options. Ideally however, such care should be provided by multi-disciplinary teams with expertise in neurology, general medicine, pain management, physical medicine and rehabilitation, as well as psychiatry. Psychiatrists as well as pain specialists can serve an essential role in leading comprehensive assessment and general management of such complex and challenging patients who are typically only partially responsive to available treatments.

    Chronic pain associated with traumatic spinal cord injury (SCI) can be quite challenging to the physiatrist. This highly prevalent condition within the SCI population requires an appropriate evaluative approach including a thorough history, a targeted physical examination, and appropriate use of diagnostic testing. The International Spinal Cord Injury Pain Classification allows for a reasonable categorization of the various pain syndromes and may assist in selecting a reasoned treatment strategy. A multitude of management approaches exist including nonpharmacologic, pharmacologic, and interventional approaches.

    Neuropathic pain (NP) arises from injuries or diseases affecting the somatosensory component of the nervous system at any level of the peripheral or central nervous system. NP is diagnosed based on common neurologic signs and symptoms. NP is best treated with a combination of multiple therapeutic approaches, and treatments include conservative, complementary, medical, interventional, and surgical treatment modalities. Goals of treatment are the same as in pain management and include improvement in pain control and in coping skills as well as restoration of functional status. Most patients with NP benefit most from an individualized, multimodal approach that emphasizes both pain and function. PMID:26614725

    Neuropathic pain is the most common type of pain in neuropathy. In painful polyneuropathies the pain usually has a "glove and stocking" distribution. The pain may be predominantly spontaneous, e.g., with a burning, pricking, or shooting character or characterized by evoked pain such as mechanical or cold allodynia. In the clinical setting, the prevention of painful neuropathies and treatment of underlying neuropathy remains inadequate and thus symptomatic treatment of the pain and related disability needs to be offered. Most randomized, double-blind, placebo-controlled trials (RCTs) published in painful neuropathy have been conducted in patients with diabetes and to what extent a treatment which is found effective in painful diabetic polyneuropathy can be expected to relieve other conditions like chemotherapy- or HIV-induced neuropathy is unknown. Tricyclic antidepressants (TCAs), gabapentin, pregabalin, and serotonin noradrenaline reuptake inhibitors (SNRIs) are first drug choices. In patients with localized neuropathic pain, a topical lidocaine patch may also be considered. Second-line treatments are tramadol and other opioids. New types of treatment include botulinum toxin type A (BTX-A), high-dose capsaicin patches, and cannabinoids. Other types of anticonvulsant drugs such as lamotrigine, oxcarbazepine, and lacosamide have a more questionable efficacy in painful polyneuropathy but may have an effect in a subgroup of patients. Combination therapy may be considered in patients with insufficient effect from one drug. Treatment is usually a trial-and-error process and has to be individualized to the single patient, taking into account all comorbidities such as possible concomitant depression, anxiety, diseases, and drug interactions. Side-effects to antidepressants include dry mouth, nausea, constipation, orthostatic hypotension, and sedation. ECG should always be obtained prior to treatment with TCAs, which also should not be used in patients with cardiac incompensation and epilepsy. The most common side-effects of gabapentin and pregabalin are CNS-related side-effects with dizziness and somnolence. Peripheral edema, weight gain, nausea, vertigo, asthenia, dry mouth, and ataxia may also occur. Topical treatments are better tolerated due to lack of systemic side-effects but there is still limited evidence for the long-term efficacy of these drugs. With available drugs, the average pain reduction is about 20-30%, and only 20-35% of the patients will achieve at least 50% pain reduction, which stresses the need of a multidisciplinary approach to pain treatment.

    The acquisition of a high adult peak bone mass (PBM) is considered an important determinant of osteoporotic risk later in life. Genetic and environmental factors determine optimal PBM acquisition in early adulthood. The aim of this study was to test the association of vitamin D receptor (VDR) gene polymorphisms and dietary calcium intake with the bone mass of young adults. The study population comprised a total of 305 individuals (mean age 20.41; SD 2.36) whose bone mass was assessed through heel ultrasound [quantitative ultrasound measurements (QUS)] measurements (BUA, dB/MHz). The FokI G/A, rs9729 G/T, and TaqI G/A polymorphisms were selected as genetic markers of VDR. A significant difference in BUA values was observed according to gender (females 82.96; SD 15.89 vs. males 97.72; SD 16.50; p < 0.00001). The mean dietary calcium intake of the study group (827.84 mg/day; SD 347.04) was lower than the dietary reference intake for young adults (1000 mg/day) and had no association with BUA. None of the three VDR polymorphisms tested showed an association with BUA. Similarly, the analysis of VDR 3' haplotypes, estimated using rs9729 and Taq1 as tag SNPs, did not reveal any significant association with QUS traits. Our results confirm the existence of different heel QUS for women and men, as well as a tendency towards low calcium consumption by young adults, and they also suggest that the VDR gene does not play a major role in the genetic determination of QUS parameter in early adulthood.

An explanation of the etiology and clinical diagnosis in relation to the differential diagnosis, treatment techniques, and patient outcomes are described. The 24-year-old female tri-athlete reported pain at Gerdy’s tubercle and lateral femoral condyle areas occurring within 2 miles of a run. VAS score was 6/10 for the running activity and the lower extremity functional scale (LEFS) score was 93% (74/80). Over the previous 2 years, the ITB symptoms had failed to resolve with extensive conservative treatment at the knee. On weight bearing, the patient demonstrated pain free limitation of active midtarsal pronation more than supination, which correlated with a decrease in passive internal rotation of the cuboid. Symptoms resolved after one cuboid whip manipulation and the patient was able to run pain free. Post-manipulation treatment consisted of two more sessions, which included motor retraining for weight bearing active midtarsal pronation and supination. LEFS was 100% (80/80) and VAS 0/10 with running greater than 10 miles. While causality cannot be inferred from a single case, this report may foster further investigation regarding the differential diagnosis and treatment of a hypomobile cuboid. PMID:24421625

    Chronic pain in incarcerated women is understudied and poorly described. Study objectives were to describe pain characteristics, correlates, and predictors in a convenience sample of incarcerated women with chronic pain. A survey packet that included the Brief Pain Inventory Short Form (BPI-SF) and the Pain Catastrophizing Scale (PCS) was distributed to all inmates at a state prison for women. Those who self-identified as having chronic pain ≥4 on a 0–10 numeric rating scale were invited to complete the survey. Demographics and medical and psychiatric diagnoses were abstracted by chart review. Participants (N=159) rated their current and average pain intensity as severe. Pain catastrophizing was found to predict average pain intensity and level of pain-related interference in functioning. Pain catastrophizing is treatable with behavioral intervention in the general population. Findings suggest that pain catastrophizing may be an important target for research and treatment in incarcerated women with chronic pain. PMID:22643606

    Introduction Comprehensive pain management services are primarily located in urban areas, limiting specialist consultation opportunities for community healthcare providers. A community of practice (CoP) for pain management could create opportunities for consultation by establishing professional relationships between community healthcare providers and pain management specialists. A CoP is a group of people with a common concern, set of problems, or a passion for something they do. Members of a CoP for pain management increase their knowledge of evidence-based pain management strategies in a way that is meaningful and relevant. In this article, we provide evidence that TelePain, an interdisciplinary, case-based pain management teleconference consultation program through the University of Washington, qualifies as a CoP and present preliminary evidence of TelePain's effectiveness as a CoP for pain management. Methods Specific behaviors and conversations gathered through participant observation during TelePain sessions were analyzed based on the 14 indicators Wegner developed to evaluate the presence of a CoP. To demonstrate preliminary effectiveness of TelePain as a CoP for pain management, descriptive statistics were used to summarize TelePain evaluation forms. Results TelePain is an example of a successful CoP for pain management as demonstrated by the presence of Wegner's 14 indicators. Additionally, evaluation forms showed that TelePain enhanced community healthcare providers' knowledge of pain management strategies and that continued participation in TelePain lead to community healthcare providers' increased confidence in their ability to provide pain management. Conclusion TelePain, a CoP for pain management, facilitates multidisciplinary collaboration and allows members to develop interdisciplinary care plans for complex pain patients through case study discussions. Evidence-based pain management strategies gained through CoP membership could be disseminated to other healthcare providers in members' clinics, which has the potential of improving the care of chronic pain patients.

    PubMed

    Adams, Michael A

    2004-12-01

    This paper offers a mechanistic account of back pain which attempts to incorporate all of the most important recent advances in spinal research. Anatomical and pain-provocation studies show that severe and chronic back pain most often originates in the lumbar intervertebral discs, the apophyseal joints, and the sacroiliac joints. Psychosocial factors influence many aspects of back pain behaviour but they are not important determinants of who will experience back pain in the first place. Back pain is closely (but not invariably) associated with structural pathology such as intervertebral disc prolapse and endplate fractures, although age-related biochemical changes such as those revealed by a 'dark disc' on MRI have little clinical relevance. All features of structural pathology (including disc prolapse) can be re-created in cadaveric specimens by severe or repetitive mechanical loading, with a combination of bending and compression being particularly harmful to the spine. Structural disruption alters the mechanical environment of disc cells in a manner that leads to cell-mediated degenerative changes, and animal experiments confirm that surgical disruption of a disc is followed by widespread disc degeneration. Some people are more vulnerable to spinal degeneration than others, largely because of their genetic inheritance. Age-related biochemical changes and loading history can also affect tissue vulnerability. Finally the concept of 'functional pathology' is introduced, according to which, back pain can arise because postural habits generate painful stress concentrations within innervated tissues, even though the stresses are not high enough to cause physical disruption.

    Nociceptive and neuropathic pain (NP) are common consequences following spinal cord injury (SCI), with large impact on sleep, mood, work, and quality of life. NP affects 40% to 50% of individuals with SCI and is sometimes considered the major problem following SCI. Current treatment recommendations for SCI-NP primarily focus on pharmacological strategies suggesting the use of anticonvulsant and antidepressant drugs, followed by tramadol and opioid medications. Unfortunately, these are only partly successful in relieving pain. Qualitative studies report that individuals with SCI-related long-lasting pain seek alternatives to medication due to the limited efficacy, unwanted side effects, and perceived risk of dependency. They spend time and money searching for additional treatments. Many have learned coping strategies on their own, including various forms of warmth, relaxation, massage, stretching, distraction, and physical activity. Studies indicate that many individuals with SCI are dissatisfied with their pain management and with the information given to them about their pain, and they want to know more about causes and strategies to manage pain. They express a desire to improve communication with their physicians and learn about reliable alternative sources for obtaining information about their pain and pain management. The discrepancy between treatment algorithms and patient expectations is significant. Clinicians will benefit from hearing the patient´s voice. PMID:23459087

    Pseudoachondroplasia (PSACH) is a well-described autosomal dominant short limb dwarfing condition caused by mutations in the cartilage oligomeric matrix protein gene (COMP). The most debilitating complication of the disorder is joint pain starting in childhood, the extent and severity of which is poorly defined. The aim of this study was to fully assess the pain and identify additional clinical complications affecting those with PSACH. An online survey was distributed to individuals with PSACH. Of the 77 surveys analyzed, 83% reported chronic pain starting as early as the newborn period. Pain was most frequently reported in weight bearing joints including the knees, hips, and back, and significantly interfered with their overall quality of life. For pain relief, patients with PSACH used a wide variety of treatments. However, patients reported only a 60% resolution of pain with their current treatments. An increase in other comorbidities was not found, specifically osteoporosis was not increased. This study documents for the first time that pain is the most common presenting symptom in PSACH and is often overlooked until short stature becomes obvious. The recognition of chronic pain as one of the earliest manifestations of PSACH is important to allow for prompt diagnosis. PMID:26177939

    Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p < 0.05). There were no between group differences in heat pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

    The musculoskeletal structures of the thoracic wall and the neck are a relatively common source of chest pain. Pain arising from these structures is often mistaken for angina pectoris, pleurisy or other serious disorders. In this article the clinical features, pathogenesis and management of the various musculoskeletal chest wall disorders are discussed. The more common causes are costochondritis, traumatic muscle pain, trauma to the chest wall, “fibrositis” syndrome, referred pain, psychogenic regional pain syndrome, and arthritis involving articulations of the sternum, ribs and thoracic spine. Careful analysis of the history, physical findings and results of investigation is essential for precise diagnosis and effective treatment. ImagesFig. 3Fig. 4Fig. 5 PMID:4027804

    Jaeger, Bernadette

    2013-01-01

    Myofascial trigger point pain is an extremely prevalent cause of persistent pain disorders in all parts of the body, not just the head, neck, and face. Features include deep aching pain in any structure, referred from focally tender points in taut bands of skeletal muscle (the trigger points). Diagnosis depends on accurate palpation with 2-4 kg/cm2 of pressure for 10 to 20 seconds over the suspected trigger point to allow the referred pain pattern to develop. In the head and neck region, cervical muscle trigger points (key trigger points) often incite and perpetuate trigger points (satellite trigger points) and referred pain from masticatory muscles. Management requires identification and control of as many perpetuating factors as possible (posture, body mechanics, psychological stress or depression, poor sleep or nutrition). Trigger point therapies such as spray and stretch or trigger point injections are best used as adjunctive therapy. PMID:24864393

  6. An archaeology of pain

    Pain is a discursive construct of science and medicine. Through the discourses of biopower and technoscience pain is used to construct and maintain the social body. Biopower and technoscience are discursive practices that are enveloped within the disciplines of Western society. Specifically, the disciplines of education, science, and medicine use biopower and technoscience to normalize the body and construct binaries which create the abnormal. The cyborg is a discursive practice used to implode the binaries of the disciplines which maintain the social body. Through the implosion of binaries, the binary of mind/body is no longer plausible in the explanation of pain. Neuropathic chronic pain and phantom limb pain become cyborg discourses which operate to deconstruct the pedagogies of science and medicine.

    Postoperative pain is a very important issue for several patients. Indifferent of the surgery type or method, pain management is very necessary. The relief from suffering leads to early mobilization, less hospital stay, reduced hospital costs, and increased patient satisfaction. An individual approach should be applied for pain control, rather than a fix dose or drugs. Additionally, medical, psychological, and physical condition, age, level of fear or anxiety, surgical procedure, personal preference, and response to agents given should be taken into account. The major goal in the management of postoperative pain is minimizing the dose of medications to lessen side effects while still providing adequate analgesia. Again a multidisciplinary team approach should be pursued planning and formulating a plan for pain relief, particularly in complicated patients, such as those who have medical comorbidities. These patients might appear increase for analgesia-related complications or side effects. PMID:25774311

    Stress fractures are frequently underdiagnosed and undertreated despite being common in sports. Early diagnosis is crucial; therefore, a high index of clinical suspicion is required. Complementary examinations are essential for diagnosis and follow-up. The authors report a clinical case of a young adult triathlon athlete referring mechanical pain in the rear left foot, with 2 weeks' progression. An earlier increase in daily training intensity was recorded. Complementary examinations confirmed a calcaneal fatigue fracture. Immobilization and no weight bearing were introduced for an initial period of 4 weeks, and the rehabilitation process was started. Progressive weight bearing was introduced between fourth and eighth weeks. Sports activity started at the 12th week. Boundaries to sports activity were eliminated by the 24th week, without pain or functional limitation. Repetitive overload to the heel and intense axial weight bearing in association to repetitive concentric/eccentric gastrocnemius contraction are related to calcaneal stress fracture, the second most common stress fracture in the foot. Calcaneal stress fractures can be adequately treated with activity modification, without casting or surgical intervention. When in the presence of bilateral stress fractures, metabolic and nutritional issues must be considered. The case report highlights the importance of sports medicine examination for detecting intrinsic and extrinsic fatigue fracture risk factors. PMID:26945212

    Pain relief is a management problem for many patients, their families, and the medical professionals caring for them. Although everyone experiences pain to some degree, responses to it vary from one person to another. Recognizing and specifying someone else’s pain is clinically a well know challenge. Research on the biology and neurobiology of pain has given us a relationship between spirituality and pain. There is growing recognition that persistent pain is a complex and multidimensional experience stemming from the interrelations among biological, psychological, social, and spiritual factors. Patients with pain use a number of cognitive and behavioral strategies to cope with their pain, including religious/spiritual factors, such as prayers, and seeking spiritual support to manage their pain. This article provides an overview of the complex phenomenon of pain, with a focus on spiritual and religious issues in pain management. PMID:26973914

    Summary Plantar fasciitis can be a chronic and debilitating condition affecting athletes of all levels. The aim of this study is to compare treatment outcomes for the treatment of chronic plantar fasciitis in athletes, comparing focused extra corporeal sound wave therapy (ESWT) and the surgical endoscopic plantar fasciotomy (EPF). A total of 37 eligible patients were enrolled in the study between May 2006 and December 2008 at a single institution. Patients were either enrolled in the surgical group, or to the ESWT group which included a placebo controlled, randomized group (P-ESWT). Pre and post Visual Analog Scores (VAS) and Roles and Maudlsey (RM) scores were recorded and compared between the three groups. The patient’s return to activity (RTA) was also documented. The results showed statistical improvement within the EPF and ESWT groups with both VAS & RM scores, with EPF being significantly better than both ESWT and P-ESWT in terms of treatment outcomes. Patients enrolled in the ESWT were able though to continue with their exercise regimen, while the EPF group was able to return to their athletic activity in an average of 2.8 months. In conclusion, EPF and ESWT are both effective forms of treatment for chronic plantar fasciitis; EPF being superior in outcomes yet ESWT treatment could be preferable since the athlete can remain active during treatment.

  14. Pain Catastrophising Affects Cortical Responses to Viewing Pain in Others

    PubMed Central

    Fallon, Nicholas

    2015-01-01

    Pain catastrophising is an exaggerated cognitive attitude implemented during pain or when thinking about pain. Catastrophising was previously associated with increased pain severity, emotional distress and disability in chronic pain patients, and is also a contributing factor in the development of neuropathic pain. To investigate the neural basis of how pain catastrophising affects pain observed in others, we acquired EEG data in groups of participants with high (High-Cat) or low (Low-Cat) pain catastrophising scores during viewing of pain scenes and graphically matched pictures not depicting imminent pain. The High-Cat group attributed greater pain to both pain and non-pain pictures. Source dipole analysis of event-related potentials during picture viewing revealed activations in the left (PHGL) and right (PHGR) paraphippocampal gyri, rostral anterior (rACC) and posterior cingulate (PCC) cortices. The late source activity (600–1100 ms) in PHGL and PCC was augmented in High-Cat, relative to Low-Cat, participants. Conversely, greater source activity was observed in the Low-Cat group during the mid-latency window (280–450 ms) in the rACC and PCC. Low-Cat subjects demonstrated a significantly stronger correlation between source activity in PCC and pain and arousal ratings in the long latency window, relative to high pain catastrophisers. Results suggest augmented activation of limbic cortex and higher order pain processing cortical regions during the late processing period in high pain catastrophisers viewing both types of pictures. This pattern of cortical activations is consistent with the distorted and magnified cognitive appraisal of pain threats in high pain catastrophisers. In contrast, high pain catastrophising individuals exhibit a diminished response during the mid-latency period when attentional and top-down resources are ascribed to observed pain. PMID:26186545

    Pain management in the elderly has increasingly become problematic in the USA as the aged population grows. The proportion of the population over 65 continues to climb and may eclipse 20 % in the next decade. In order to effectively diagnosis and treat these patients, a proper history and physical exam remain essential; pain assessment scales such as the Verbal Descriptor Scales (VDS), the Numerical Rating Scales (NRS), and the Visual Analogue Scales (VAS) often but not always prove beneficial. The conditions most frequently afflicting this population include osteoarthritis, diabetic neuropathy, post-herpetic neuralgia, and lower back pain which include spondylosis and radiculopathies. While the normal aging process does not necessarily guarantee symptoms of chronic pain, elderly individuals are far more likely to develop these painful conditions than their younger counterparts. There are many effective treatment modalities available as potential therapeutic interventions for elderly patients, including but not limited to analgesics such as NSAIDs and opioids, as well as multiple interventional pain techniques. This review will discuss chronic pain in the elderly population, including epidemiology, diagnostic tools, the multitude of co-morbidities, and common treatment modalities currently available to physicians.

    Low back pain is a leading cause of disability. It occurs in similar proportions in all cultures, interferes with quality of life and work performance, and is the most common reason for medical consultations. Few cases of back pain are due to specific causes; most cases are non-specific. Acute back pain is the most common presentation and is usually self-limiting, lasting less than three months regardless of treatment. Chronic back pain is a more difficult problem, which often has strong psychological overlay: work dissatisfaction, boredom, and a generous compensation system contribute to it. Among the diagnoses offered for chronic pain is fibromyalgia, an urban condition (the diagnosis is not made in rural settings) that does not differ materially from other instances of widespread chronic pain. Although disc protrusions detected on X-ray are often blamed, they rarely are responsible for the pain, and surgery is seldom successful at alleviating it. No single treatment is superior to others; patients prefer manipulative therapy, but studies have not demonstrated that it has any superiority over others. A WHO Advisory Panel has defined common outcome measures to be used to judge the efficacy of treatments for studies. PMID:14710509

    Quantitative ultrasound of the heel captures heel bone properties that independently predict fracture risk and, with bone mineral density (BMD) assessed by X-ray (DXA), may be convenient alternatives for evaluating osteoporosis and fracture risk. We performed a meta-analysis of genome-wide association (GWA) studies to assess the genetic determinants of heel broadband ultrasound attenuation (BUA; n = 14 260), velocity of sound (VOS; n = 15 514) and BMD (n = 4566) in 13 discovery cohorts. Independent replication involved seven cohorts with GWA data (in silico n = 11 452) and new genotyping in 15 cohorts (de novo n = 24 902). In combined random effects, meta-analysis of the discovery and replication cohorts, nine single nucleotide polymorphisms (SNPs) had genome-wide significant (P < 5 × 10(-8)) associations with heel bone properties. Alongside SNPs within or near previously identified osteoporosis susceptibility genes including ESR1 (6q25.1: rs4869739, rs3020331, rs2982552), SPTBN1 (2p16.2: rs11898505), RSPO3 (6q22.33: rs7741021), WNT16 (7q31.31: rs2908007), DKK1 (10q21.1: rs7902708) and GPATCH1 (19q13.11: rs10416265), we identified a new locus on chromosome 11q14.2 (rs597319 close to TMEM135, a gene recently linked to osteoblastogenesis and longevity) significantly associated with both BUA and VOS (P < 8.23 × 10(-14)). In meta-analyses involving 25 cohorts with up to 14 985 fracture cases, six of 10 SNPs associated with heel bone properties at P < 5 × 10(-6) also had the expected direction of association with any fracture (P < 0.05), including three SNPs with P < 0.005: 6q22.33 (rs7741021), 7q31.31 (rs2908007) and 10q21.1 (rs7902708). In conclusion, this GWA study reveals the effect of several genes common to central DXA-derived BMD and heel ultrasound/DXA measures and points to a new genetic locus with potential implications for better understanding of osteoporosis pathophysiology.

    Accurate recognition and quantification of pain in horses is imperative for adequate pain management. The past decade has seen a much needed surge in formal development of systematic pain assessment tools for the objective monitoring of pain in equine patients. This narrative review describes parameters that can be used to detect pain in horses, provides an overview of the various pain scales developed (visual analogue scales, simple descriptive scales, numerical rating scales, time budget analysis, composite pain scales and grimace scales), and highlights their strengths and weaknesses for potential clinical implementation. The available literature on the use of each pain assessment tool in specific equine pain states (laminitis, lameness, acute synovitis, post-castration, acute colic and post-abdominal surgery) is discussed, including any problems with sensitivity, reliability or scale validation as well as translation of results to other clinical pain states. The review considers future development and further refinement of currently available equine pain scoring systems. PMID:26831169

    Patients who have lateral hip pain historically have been diagnosed with trochanteric bursitis and treated with nonsteroidal anti-inflammatory medications, corticosteroid injections, and physical therapy. Although this strategy is effective for most patients, a substantial number of patients continue to have pain and functional limitations. Over the past decade, our understanding of disorders occurring in the peritrochanteric space has increased dramatically. Greater trochanteric pain syndrome encompasses trochanteric bursitis, external coxa saltans (ie, snapping hip), and abductor tendinopathy. A thorough understanding of the anatomy, examination findings, and imaging characteristics aids the clinician in treating these patients. Open and endoscopic treatment options are available for use when nonsurgical treatment is unsuccessful. PMID:26990713

    Nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of depression, and heightened illness concern determine a substantial percentage of the disability associated with puzzling hand and arm pains. Ergonomic modifications can help to control symptoms, but optimal health may require collaborative management incorporating psychosocial and psychological elements of illness. PMID:25207288

    Modern cancer therapies have significantly increased patient survival rates in both human and veterinary medicine. Since cancer patients live longer they now face new challenges resulting from severe, chronic tumor-induced pain. Unrelieved cancer pain significantly decreases the quality of life of such patients; thus the goal of pain management is to not only to alleviate pain, but also to maintain the patient's physiological and psychological well-being. The major impediment for developing new treatments for cancer pain has been our limited knowledge of the basic mechanisms that drive cancer pain and the lack of adequate animal cancer pain models to study the molecular, biochemical and neurobiological pathways that generate and maintain cancer pain. However this situation has recently changed with the recent development of several novel animal models of cancer pain. This review will focus on describing these animal models, many of them in rodents, and reviewing some of the recent information gained from the use of these models to investigate the basic mechanims that underlie the development and maintenance of cancer pain. Animal models of cancer pain can be divided into the following five categories: bone cancer pain models, non-bone cancer pain models, cancer invasion pain models, cancer chemotherapeutic-induced peripheral neuropathy models, and spontaneous occurring cancer pain models. These models will be important not only for enhancing our knowledge of how cancer pain is generated, but more importantly for the development of novel therapeutic regimes to treat cancer pain in both domestic animals and humans.

  5. Postamputation pain: studies on mechanisms.

    PubMed

    2012-10-01

    Amputation is followed by both painful and non-painful phantom phenomena in a large number of amputees. Non-painful phantom sensations rarely pose any clinical problem, but 60-80% of all amputees also experience painful sensations (i.e. phantom pain) located to the missing limb. The severity of phantom pain usually decreases with time, but severe pain persists in 5-10% of patients. Pain in the residual limb (i.e. stump pain) is another consequence of amputation. Both stump and phantom pain can be very difficult to treat. Treatment guidelines used for other neuropathic pain conditions are probably the best approximation, especially for the treatment of stump pain. The aim of the present doctoral thesis was to explore some of the mechanisms underlying pain after amputation. Ten studies were carried out (I-X). My PhD thesis from 1998 dealt with pain before the amputation and showed that preamputation pain increases the risk of phantom pain after amputation (I). A perioperative epidural blockade, however, did not reduce the incidence of pain or abnormal sensory phenomena after amputation (II, III). The importance of sensitization before amputation for the subsequent development of pain is supported by study IV, in which pressure pain thresholds obtained at the limb before amputation were inversely related to stump and phantom pain after 1 week. Afferent input from the periphery is likely to contribute to postamputation pain as sodium channels were upregulated in human neuromas (VI), although neuroma removal did not always alleviate phantom pain (V). Sensitization of neurons in the spinal cord also seems to be involved in pain after amputation as phantom pain was reduced by ketamine, an NMDA-receptor antagonist. Another NMDA-receptor antagonist, memantine, and gabapentin, a drug working by binding to the δ2α-subunit of voltage-gated calcium channels, had no effect on phantom pain (VII-IX). Supraspinal factors are also important for pain after amputation as catastrophizing was associated with phantom pain (X). In conclusion, the present doctoral thesis confirmed and expanded the findings by others that several mechanisms are involved in the development and maintenance of phantom pain. A better understanding of the underlying mechanisms will hopefully lead to improved treatment of pain after amputation in the future. PMID:23158899

    2007-01-01

    Neuropathic pain refers to pain that originates from pathology of the nervous system. Diabetes, infection (herpes zoster),nerve compression, nerve trauma, “channelopathies,” and autoimmune disease are examples of diseases that maycause neuropathic pain. The development ofbothanimal models and newer pharmacological strategies has led to an explosion of interest in the underlying mechanisms. Neuropathic pain reflects both peripheral and central sensitization mechanisms. Abnormal signals arise not only from injured axons but also from the intact nociceptors that share the innervation territory of the injured nerve. This review focuses on how both human studies and animal models are helping to elucidate the mechanisms underlying these surprisingly common disorders. The rapid gain in knowledge about abnormal signaling promises breakthroughs in the treatment of these often debilitating disorders. PMID:17015228

    Greater trochanteric pain is one of the common complaints in orthopedics. Frequent diagnoses include myofascial pain, trochanteric bursitis, tendinosis and rupture of the gluteus medius and minimus tendon, and external snapping hip. Furthermore, nerve entrapment like the piriformis syndrome must be considered in the differential diagnosis. This article summarizes essential diagnostic and therapeutic steps in greater trochanteric pain syndrome. Careful clinical evaluation, complemented with specific imaging studies and diagnostic infiltrations allows determination of the underlying pathology in most cases. Thereafter, specific nonsurgical treatment is indicated, with success rates of more than 90 %. Resistant cases and tendon ruptures may require surgical intervention, which can provide significant pain relief and functional improvement in most cases. PMID:24414233

    Newborns are often subjected to invasive and painful medical procedures. This happens even more frequently when they require hospitalization. The aim of this paper was to evaluate pain in healthy newborns and in newborns with Down syndrome (DS). We performed a prospective cohort study in the neonatal service of the San Cecilio University Hospital in Granada (Spain) from January 2008 to September 2013. The universe of our study comprised a study group of 20 newborns with DS and a control group of 20 newborns without DS. All of the infants were hospitalized, and thus had to undergo painful medical procedures. The variables studied were basal recovery time (as reflected in crying and the normalization of biological constants), number of punctures, oxygen saturation, heartbeat, blood pressure, response to skin-to-skin contact, and gestational age. The evaluation was performed during blood extraction, vein canalization, and heel puncture. The significant differences in the basal recovery time between the two groups of newborns indicated that those with DS were slower to express pain, and when they did, their response was not as clearly defined as that of babies without DS. The oxygen saturation in babies with DS after the puncture was found to be significantly lower than that of the control group (p < .001). The results of this study revealed that babies with DS were not as quick to perceive pain after a puncture. However, when pain was finally perceived, it persisted for a longer time. This situation should be taken into account in the design of pharmacologic and nonpharmacologic therapies. PMID:25439126

    Low back pain is one of the most common and costly afflictions of our Society. The majority of adults will have at least one episode of acute low back pain that will likely resolve regardless of treatment. Lumbar spine radiographs are overused and there is little scientific support for many of the therapeutic interventions advocated. Even for those patients with symptomatic herniated disc, only a small fraction will ultimately require surgical intervention. PMID:2930949

  1. Low back pain (acute)

    PubMed Central

    2011-01-01

    Introduction Low back pain affects about 70% of people in resource-rich countries at some point in their lives. Acute low back pain can be self-limiting; however, 1 year after an initial episode, as many as 33% of people still have moderate-intensity pain and 15% have severe pain. Acute low back pain has a high recurrence rate; 75% of those with a first episode have a recurrence. Although acute episodes may resolve completely, they may increase in severity and duration over time. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of oral drug treatments for acute low back pain? What are the effects of local injections for acute low back pain? What are the effects of non-drug treatments for acute low back pain? We searched: Medline, Embase, The Cochrane Library, and other important databases up to December 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 49 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, advice to stay active, analgesics (paracetamol, opioids), back exercises, back schools, bed rest, behavioural therapy, electromyographic biofeedback, epidural corticosteroid injections, lumbar supports, massage, multidisciplinary treatment programmes, muscle relaxants, non-steroidal anti-inflammatory drugs (NSAIDs), spinal manipulation, temperature treatments (short-wave diathermy, ultrasound, ice, heat), traction, and transcutaneous electrical nerve stimulation (TENS).

    Groin pain is a common and often frustrating problem in athletes who engage in sports involving kicking, rapid accelerations and decelerations, and sudden direction changes. The most common problems are adductor strain, osteitis pubis, and sports hernia. Other causes must be considered, including nerve pain, stress fractures, and intrinsic hip pathology. There is significant overlap and multiple problems frequently coexist. Accurate diagnosis leads to directed treatment, with rehabilitation focused on functional closed-chain strengthening and core stability. PMID:17067496

    The under-treatment of postoperative pain has been recognised to delay patient recovery and discharge from hospital. Despite recognition of the importance of effective pain control, up to 70% of patients still complain of moderate to severe pain postoperatively. The mechanistic approach to pain management, based on current understanding of the peripheral and central mechanisms involved in nociceptive transmission, provides newer options for clinicians to manage pain effectively. In this article we review the rationale for a multimodal approach with combinations of analgesics from different classes and different sites of analgesic administration. The pharmacological options of commonly used analgesics, such as opioids, NSAIDs, paracetamol, tramadol and other non-opioid analgesics, and their combinations is discussed. These analgesics have been shown to provide effective pain relief and their combinations demonstrate a reduction in opioid consumption. The basis for using non-opioid analgesic adjuvants is to reduce opioid consumption and consequently alleviate opioid-related adverse effects. We review the evidence on the opioid-sparing effect of ketamine, clonidine, gabapentin and other novel analgesics in perioperative pain management. Most available data support the addition of these adjuvants to routine analgesic techniques to reduce the need for opioids and improve quality of analgesia by their synergistic effect. Local anaesthetic infiltration, epidural and other regional techniques are also used successfully to enhance perioperative analgesia after a variety of surgical procedures. The use of continuous perineural techniques that offer prolonged analgesia with local anaesthetic infusion has been extended to the care of patients beyond hospital discharge. The use of nonpharmacological options such as acupuncture, relaxation, music therapy, hypnosis and transcutaneous nerve stimulation as adjuvants to conventional analgesia should be considered and incorporated to achieve an effective and successful perioperative pain management regimen.

    Most lumbar disk herniations improve over time with or without medical treatment. Disk herniations and annular tears may not be symptomatic and are shown to exist in patients without any symptoms. In some patients, chronic low back pain may result from the syndrome of internal disk disruption. Treatment of chronic pain of diskal cause can be challenging and have varying results in terms of success. The diagnosis, cause, and treatment options are reviewed in this article. PMID:24787335

    2016-05-01

    Nociception is the process of transmission of painful signals by nociceptors in the primary afferent nerve fibers, which specifically respond to noxious stimuli. These noxious stimuli are detected by nociceptors and converted into electrical signals, which are then transmitted to the spinal cord, thalamus, and the cerebral cortex, where pain is finally sensed. Transient receptor potential (TRP) ion channels have emerged as a family of evolutionarily conserved ligand-gated ion channels that function as molecular detectors of physical stimuli. Several member of this family, at least six channels from three TRP family subtypes (TRPV1-4, TRPM8, and TRPA1), are expressed in nociceptors, where they act as transducers for signals from thermal, chemical, and mechanical stimuli and play crucial roles in the generation and development of pathological pain perception. This review focuses on the increasing evidence of TRP channel involvement and contribution in nociceptive pain and the pain hypersensitivity associated with peripheral inflammation or neuropathy, and on the renewed interest in targeting TRP channels for pain relief.

  6. Myofascial Head Pain.

    Muscle nociception is mainly characterized by local tenderness and referred pain. The neurophysiological basis of muscle pain supports a role of sensitization mechanisms. From a clinical viewpoint, muscle pain is represented by the presence of myofascial trigger points (TrPs). Evidence suggests that TrPs are able to start a peripheral nociceptive mechanism and hence contributing to changes in the central nervous system. Several studies demonstrated that the referred pain elicited by TrPs reproduces the headache pattern in patients with tension-type headache (TTH), migraine, cervicogenic headache and, in some individuals, with cluster headache. In fact, sensitization of nociceptive pain pathways in the central nervous system due to prolonged nociceptive stimuli from TrPs seems to be responsible for the conversion of episodic to chronic TTH. In other headaches, TrPs may be able to stimulate the trigeminal nucleus caudalis and hence triggering a migraine or cluster headache attack. Proper treatment directed towards TrP inactivation has documented positive effects in individuals with these headaches; however, longitudinal studies are needed to further determine the role of TrPs in head pain.

  7. Mechanisms of Myofascial Pain

    Myofascial pain syndrome is an important health problem. It affects a majority of the general population, impairs mobility, causes pain, and reduces the overall sense of well-being. Underlying this syndrome is the existence of painful taut bands of muscle that contain discrete, hypersensitive foci called myofascial trigger points. In spite of the significant impact on public health, a clear mechanistic understanding of the disorder does not exist. This is likely due to the complex nature of the disorder which involves the integration of cellular signaling, excitation-contraction coupling, neuromuscular inputs, local circulation, and energy metabolism. The difficulties are further exacerbated by the lack of an animal model for myofascial pain to test mechanistic hypothesis. In this review, current theories for myofascial pain are presented and their relative strengths and weaknesses are discussed. Based on new findings linking mechanoactivation of reactive oxygen species signaling to destabilized calcium signaling, we put forth a novel mechanistic hypothesis for the initiation and maintenance of myofascial trigger points. It is hoped that this lays a new foundation for understanding myofascial pain syndrome and how current therapies work, and gives key insights that will lead to the improvement of therapies for its treatment.

    This study examines retrospectively the cause, clinical features, natural history and results of treatment of intractable pain associated with breast cancer in 210 patients. The three chief types of pain were that due to skeletal metastases or brachial plexus neuropathy and pain of psychogenic origin. Onset at the time of cancer diagnosis characterized the psychogenic pain, whereas pain from metastases first occurred after a median latency of 3.7 years. Treatment was custom-tailored to the specific patient and pain problem, with several factors taken into account. The onset of intractable pain due to metastatic disease indicated a short survival (median, 9 months). PMID:6277445

  9. Tradeoffs between impact loading rate, vertical impulse and effective mass for walkers and heel strike runners wearing footwear of varying stiffness.

    Humans experience repetitive impact forces beneath the heel during walking and heel strike running that cause impact peaks characterized by high rates and magnitudes of loading. Impact peaks are caused by the exchange of momentum between the ground and a portion of the body that comes to a full stop (the effective mass) during the period of the impact peak. A number of factors can influence this exchange of momentum, including footwear stiffness. This study presents and tests an impulse-momentum model of impact mechanics which predicts that effective mass and vertical impulse is greater in walkers and heel strike runners wearing less stiff footwear. The model also predicts a tradeoff between impact loading rate and effective mass, and between impact loading rate and vertical impulse among individuals wearing footwear of varying stiffness. We tested this model using 19 human subjects walking and running in minimal footwear and in two experimental footpads. Subjects walked and ran on an instrumented treadmill and 3D kinematic data were collected. As predicted, both vertical impulse (walking: F(2,54)=52.0, p=2.6E-13; running: F(2,54)=25.2, p=1.8E-8) and effective mass (walking: F(2,54)=12.1, p=4.6E-5; running: F(2,54)=15.5, p=4.7E-6) increase in less stiff footwear. In addition, there is a significant inverse relationship between impact loading rate and vertical impulse (walking: r=-0.88, p<0.0001; running: r=-0.78, p<0.0001) and between impact loading rate and effective mass (walking: r=-0.88, p<0.0001; running: r=-0.82, p<0.0001). The tradeoff relationships documented here raise questions about how and in what ways the stiffness of footwear heels influence injury risk during human walking and running. PMID:25814181

    Persistent or chronic pain is tightly associated with various environmental changes and linked to abnormal gene expression within cells processing nociceptive signaling. Epigenetic regulation governs gene expression in response to environmental cues. Recent animal model and clinical studies indicate that epigenetic regulation plays an important role in the development/maintenance of persistent pain and, possibly the transition of acute pain to chronic pain, thus shedding light in a direction for development of new therapeutics for persistent pain.

    Even though painful experiences are employed within social rituals across the world, little is known about the social effects of pain. We examined the possibility that painful experiences can promote cooperation within social groups. In Experiments 1 and 2, we induced pain by asking some participants to insert their hands in ice water and to perform leg squats. In Experiment 3, we induced pain by asking some participants to eat a hot chili pepper. Participants performed these tasks in small groups. We found evidence for a causal link: Sharing painful experiences with other people, compared with a no-pain control treatment, promoted trusting interpersonal relationships by increasing perceived bonding among strangers (Experiment 1) and increased cooperation in an economic game (Experiments 2 and 3). Our findings shed light on the social effects of pain, demonstrating that shared pain may be an important trigger for group formation. PMID:25193943

    Poorly controlled cancer pain is a significant public health problem throughout the world. There are many barriers that lead to undertreatment of cancer pain. One important barrier is inadequate measurement and assessment of pain. To address this problem, the Pain Research Group of the WHO Collaborating Centre for Symptom Evaluation in Cancer Care has developed the Brief Pain Inventory (BPI), a pain assessment tool for use with cancer patients. The BPI measures both the intensity of pain (sensory dimension) and interference of pain in the patient's life (reactive dimension). It also queries the patient about pain relief, pain quality, and patient perception of the cause of pain. This paper describes the development of the Brief Pain Inventory and the various applications to which the BPI is suited. The BPI is a powerful tool and, having demonstrated both reliability and validity across cultures and languages, is being adopted in many countries for clinical pain assessment, epidemiological studies, and in studies of the effectiveness of pain treatment.

    Proteomics may have enabled the root cause of a major human-blinding condition, age-related cataract, to be established. Cataract appears to result from the spontaneous decomposition of long-lived macromolecules in the human lens, and recent proteomic analysis has enabled both the particular crystallins, and the specific sites of amino acid modification within each polypeptide, to be identified. Analysis of proteins from cataract lenses has demonstrated that there are key sites on some structural proteins that show a consistently greater degree of deterioration than age-matched normal lenses. Proteomic analysis, using MS, revealed that the most abundant posttranslational modification of aged lens proteins is racemization. This is somewhat ironic, since structural isomers can be viewed as the "Achilles heel" of MS and there are typically few, if any, differences in the MS/MS spectra of tryptic peptides containing one d-amino acid. It is proposed that once a certain level of spontaneous PTM at key sites occurs, that protein-protein interactions are disrupted, and binding of complexes to cell membranes takes place that impairs cell-to-cell communication. These findings may apply more widely to age-related human diseases, in particular where the deterioration of long-lived proteins is a crucial component in the etiology. PMID:24458544

    Mechanical loading of the Achilles tendon during isolated eccentric contractions could induce immediate and region-dependent changes in mechanical properties. Three-dimensional ultrasound was used to examine the immediate effect of isolated eccentric exercise on the mechanical properties of the distal (free tendon) and proximal (gastrocnemii) regions of the Achilles tendon. Participants (n = 14) underwent two testing sessions in which tendon measurements were made at rest and during a 30% and 70% isometric plantar flexion contractions immediately before and after either: (a) 3 × 15 eccentric heel drops or (b) 10-min rest. There was a significant time-by-session interaction for free tendon length and strain for all loading conditions (P < 0.05). Pairwise comparisons revealed a significant increase in free tendon length and strain at all contraction intensities after eccentric exercise (P < 0.05). There was no significant time-by-session interaction for the gastrocnemii (medial or lateral) aponeurosis or tendon for any of the measured parameters. Immediate changes in Achilles tendon mechanical properties were specific to the free tendon and consistent with changes due to mechanical creep. These findings suggest that the mechanical properties of the free tendon may be more vulnerable to change with exercise compared with the gastrocnemii aponeurosis or tendon. PMID:25919320

    This study aimed to assess the effect of lateral heel studs on foot-ground interaction in the horse by quantifying foot slip during stance whilst cantering on a grass surface. It was hypothesised that using studs would decrease foot slip distance on the ground conditions tested. Nine horses were ridden with and without a stud placed laterally in the shoe of each of the 4 feet. High speed video-analysis was used to track hoof markers and to provide data quantifying foot slip distance, slip duration and stance duration. Using studs resulted in a significant decrease in foot slip distance in all four limbs (all P values<0.004). The magnitude of the difference in slip distance with and without studs was greatest in the trailing limbs. The results supported the hypothesis that using studs will decrease foot slip distance in horses cantering on a grass surface, and additionally, highlights that stud efficacy may vary between limbs. The decrease in slip distance with studs demonstrated increased traction and a more stable foot-ground interaction, although this may cause a concomitant increase in the required energy dissipation, either within the limb or via surface deformation. The effect of repetitive usage of studs in the aetiology of musculoskeletal conditions should therefore be investigated further. PMID:21752677

    Revision tarsal tunnel surgery was performed on 44 patients (two bilaterally). The surgical procedure included a neurolysis of the tibial nerve in the tarsal tunnel, the medial plantar, lateral plantar, and calcaneal nerves in their respective tunnels, excision of the intertunnel septum, and neuroma resection as indicated. A painful tarsal tunnel scar or painful heel was treated, respectively, by resection of the distal saphenous nerve or a calcaneal nerve branch. Postoperative, immediate ambulation was permitted. Outcomes were assessed with a numerical grading scale that included neurosensory measurements. Outcomes were also assessed by patient satisfaction and their own estimate of residual pain and/or numbness. Mean follow-up time was 2.2 years. Outcomes in terms of patient satisfaction were 54% excellent, 24% good, 13% fair, and 9% poor results. The mean preoperative numerical score was 6.0 and the mean postoperative score was 2.7. There was a significant improvement seen, based on the median difference between scores (P<0.001). Prognostic indicators of poor results in our patient group were coexisting lumbosacral disc disease and/or neuropathy. An approach related to resecting painful cutaneous nerves and neurolysis of all tibial nerve branches at the ankle offers hope for relief of pain and recovery of sensation for the majority of patients with failed previous tarsal tunnel surgery.

    Abstract Patients frequently suffer from lumbosacral plexus disorder. When conducting a neurological examination, it is essential to assess the extent of muscle paresis, sensory disorder distribution, pain occurrence, and blocked spine. An electromyography (EMG) can confirm axonal lesions and their severity and extent, root affliction (including dorsal branches), and disorders of motor and sensory fiber conduction. Imaging examination, particularly gadolinium magnetic resonance imaging (MRI) examination, ensues. Cerebrospinal fluid examination is of diagnostic importance with radiculopathy, neuroinfections, and for evidence of immunoglobulin synthesis. Differential diagnostics of lumbosacral plexopathy (LSP) include metabolic, oncological, inflammatory, ischemic, and autoimmune disorders. In the presented case study, a 64-year-old man developed an acute onset of painful LSP with a specific EMG finding, MRI showing evidence of plexus affliction but not in the proximal part of the roots. Painful plexopathy presented itself with severe muscle paresis in the femoral nerve and the obturator nerve innervation areas, and gradual remission occurred after 3 months. Autoimmune origin of painful LSP is presumed. We describe a rare case of patient with painful lumbar plexopathy, with EMG findings of axonal type, we suppose of autoimmune etiology. PMID:25929915

    As the biological alarm of impending or actual tissue damage, pain is essential for our survival. However, when it is initiated and/or sustained by dysfunctional elements in the nociceptive system, it is itself a disease known as neuropathic pain. While the critical nociceptive system provides a number of protective functions, it is unique in its central role of monitoring, preserving and restoring the optical tear film in the face of evaporative attrition without which our vision would be non-functional. Meeting this existential need resulted in the evolution of the highly complex, powerful and sensitive dry eye alarm system integrated in the peripheral and central trigeminal sensory network. The clinical consequences of corneal damage to these nociceptive pathways are determined by the type and location of its pathological elements and can range from the spectrum known as dry eye disease to the centalised oculofacial neuropathic pain syndrome characterised by a striking disparity between the high intensity of symptoms and paucity of external signs. These changes parallel those observed in somatic neuropathic pain. When seen through the neuroscience lens, diseases responsible for inadequately explained chronic eye pain (including those described as dry eye) can take on new meanings that may clarify long-standing enigmas and point to new approaches for developing preventive, symptomatic and disease-modifying interventions for these currently refractory disorders.

    The aim of this study was to evaluate the effectiveness of oral sucrose in decreasing pain during minor procedures in infants of 1-6 months corrected age. A blinded randomized controlled trial with infants aged 4-26 weeks who underwent venipuncture, heel lance or intravenous cannulation were stratified by corrected age into > 4-12 weeks and > 12-26 weeks. They received 2 mL of either 25% sucrose or sterile water orally 2 minutes before the painful procedure. Nonnutritional sucking and parental comfort, provided in adherence to hospital guidelines, were recorded. Pain behavior was recorded using a validated 10 point scale at baseline, during and following the procedure. Data collectors were blinded to the intervention. A total of 21 and 20 infants received sucrose and water, respectively, in the > 4-12-week age group, and 21 and 22, respectively, in the > 12-26-week age group. No statistical differences were found in pain scores between treatment and control groups at any data collection points in either age group. Infants aged > 4-12 weeks who did nonnutritional sucking showed statistically significantly lower median pain scores at 1, 2, and 3 minutes after the procedure than those who did not suck. Infants aged > 4-26 weeks exhibited pain behavior scores that indicated moderate to large pain during painful procedures; however, there was insufficient evidence to show that 2 mL 25% sucrose had a statistically significant effect in decreasing pain. Infants should be offered nonnutritional sucking in compliance with the Baby Friendly Health Initiative during painful procedures. PMID:24315282

    The present study examined the association between positive traits, pain catastrophizing, and pain perceptions. We hypothesized that pain catastrophizing would mediate the relationship between positive traits and pain. First, participants (n = 114) completed the Trait Hope Scale, the Life Orientation Test- Revised, and the Pain Catastrophizing Scale. Participants then completed the experimental pain stimulus, a cold pressor task, by submerging their hand in a circulating water bath (0º Celsius) for as long as tolerable. Immediately following the task, participants completed the Short-Form McGill Pain Questionnaire (MPQ-SF). Pearson correlation found associations between hope and pain catastrophizing (r = −.41, p < .01) and MPQ-SF scores (r = −.20, p < .05). Optimism was significantly associated with pain catastrophizing (r = −.44, p < .01) and MPQ-SF scores (r = −.19, p < .05). Bootstrapping, a non-parametric resampling procedure, tested for mediation and supported our hypothesis that pain catastrophizing mediated the relationship between positive traits and MPQ-SF pain report. To our knowledge, this investigation is the first to establish that the protective link between positive traits and experimental pain operates through lower pain catastrophizing. PMID:22199416

    Background Chronic pain after surgery occurs in 10-40% of individuals, including 5-20% of women after cesarean delivery in previous reports. Pain and depression 2 months after childbirth are independently associated with more severe acute post-delivery pain. Here we examine other predictors of pain at 2 months and determine the incidence of pain at 6 and 12 months after childbirth. Methods Following Institutional Review Board approval, 1228 women were interviewed within 36 hr of delivery. Of these, 937 (76%) were successfully contacted by telephone at 2 months, and, if they had pain, at 6 and 12 months after delivery. The primary outcome measure was presence of pain which began at the time of delivery. We also generated a model of severity of acute post-delivery pain and 2 month pain and depression. Results Pain which began at the time of delivery was remarkably rare 6 and 12 months later (1.8% and 0.3% [upper 95% confidence limit, 1.2%], respectively). Past history of pain and degree of tissue damage at delivery accounted for 7.0% and 16.7%, respectively of one aspect in the variability in acute post-delivery pain. Neither of these factors was associated with incidence of pain 2 months later. Conclusions Using a definition of new onset pain from delivery, we show a remarkably low incidence of pain 1 year after childbirth, including those with surgical delivery. Additionally, degree of tissue trauma and history of chronic pain, risk factors for pain 2 months after other surgery, were unimportant to pain 2 months after cesarean or vaginal delivery.

The syndrome is characterized by severe intermittent or persistent flank pain, either unilateral or bilateral, associated with gross or microscopic hematuria. LPHS is a diagnosis of exclusion as there still is not a consensus of validated diagnostic criteria, though several criteria have been proposed. The wide differential diagnosis would suggest a meticulous yet specific diagnostic work-up depending on the individual clinical features and natural history. Several mechanisms regarding the pathophysiology of LPHS have been proposed but without pinpointing the actual causative etiology, the treatment remains symptomatic. Treatment modalities for LPHS are diverse including simple analgesia, opioid analgesic and kidney autotransplantation. This review article summarizes the current understanding regarding the pathophysiology of LPHS along with the steps required for proper diagnosis and a discussion of the different therapeutic approaches for LPHS.

    Morris (1991) divides pain into two categories--physical and mental; he calls it the "Myth of Two Pains." He rationalizes that it is difficult to separate the pain of mind and body and that they are interdependent, e.g. one mind and body. However, this paper will limit itself to the history, philosophy, and psychology of physical pain (both acute and chronic) from ancient days to the twentieth century. It will not discuss mental or psychosomatic pain; nor will it include the anatomical, biochemical, pharmacological, and physiological aspects of modern methods of chronic pain control, e.g. psychotherapy, psychoanalysis, biofeedback, etc. PMID:11813376

    Complex regional pain syndrome (CRPS) previously known as reflex sympathetic dystrophy is a chronic neurological disorder involving the limbs characterized by disabling pain, swelling, vasomotor instability, sudomotor abnormality, and impairment of motor function. CRPS is not uncommon after hand surgery and may complicate post-operative care. There is no specific diagnostic test for CRPS and the diagnosis is based on history, clinical examination, and supportive laboratory findings. Recent modifications to diagnostic criteria have enabled clinicians to diagnose this disease more consistently. This review gives a synopsis of CRPS and discusses the diagnosis, pathophysiology, and treatment options based on the limited evidence in the literature. PMID:22022040

    Abstract Objective To describe the characteristics of patients with chronic noncancer pain (CNCP) prescribed opioids by community physicians and referred to a tertiary pain clinic. Design Cross-sectional, descriptive study. Setting A tertiary care, hospital-based pain clinic in Toronto, Ont. Participants A total of 455 consecutive patients newly referred to the pain clinic by community physicians. Main outcome measures Data on demographic characteristics, pain ratings, and medication intake were obtained using standardized collection forms and retrospective chart review. Patients were classified by diagnosis: group 1 patients had biomedical disorders only, group 2 patients had biomedical disorders and psychological factors, and group 3 patients had psychological factors only. Patients were also categorized based on opioid use: no opioid use (NOU); low opioid use (LOU), with a daily morphine-equivalent dosage (MED) of 200 mg or less; or high opioid use (HOU), with a daily MED of more than 200 mg. Results In the general study population, 63% of patients were taking opioids, with 1 in 5 exceeding an MED of 200 mg daily. In group 1, 59% of patients used opioids and 10% had HOU; 66% of patients in groups 2 and 3 were taking opioids, with 21% and 26% classified as having HOU. The mean (SD) daily MED for groups 2 and 3 HOU patients combined was significantly higher than that of group 1 HOU patients: 575.7 (472.9) mg/d versus 284.9 (74.6) mg/d, respectively. Men were twice as likely as women to have HOU; Canadian-born patients were 3 times as likely as foreign-born patients to have HOU. Psychoactive drugs were coprescribed in 61% of LOU patients and 76% of HOU patients. Greater opioid use was associated with group 2 and 3 diagnoses, male sex, Canadian-born origin, and high pain scores. Conclusion Our results indicate that male, Canadian-born CNCP patients presenting with psychological morbidity or comorbidity and reporting higher pain severity ratings were more likely to receive opioids. Additionally, many CNCP patients referred to our tertiary care pain clinic were receiving opioids in excess of a 200-mg/d MED. More studies are needed to determine which factors lead to high-dose opioid prescribing in a subset of this CNCP population. PMID:21402957

Treatment for NCCP has markedly evolved in the past decade and is presently focused on gastroesophageal reflux disease (GERD) and visceral hypersensitivity. Aggressive treatment with proton pump inhibitors has become the standard of care for GERD-related NCCP. Pain modulators such as tricyclics, trazodone, and selective serotonin reuptake inhibitors are considered the mainstay of therapy for non-GERD-related NCCP Other therapeutic modalities such as botulinum toxin injections and hypnotherapy have demonstrated promise in small clinical trials.

    In patients with active cancer, the management of chronic pain is an essential element in a comprehensive strategy for palliative care. This strategy emphasises multidimensional assessment and the coordinated use of treatments that together mitigate suffering and provide support to the patient and family. This review describes this framework, an approach to pain assessment, and widely accepted techniques to optimise the safety and effectiveness of opioid drugs and other treatments. The advances of recent decades suggest a future that includes increased evidence-based targeting of specific analgesic interventions within an individualised plan of care that is appropriate throughout the course of illness.

    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation. PMID:27133242

    Musculoskeletal complaints account for about 20% to 30% of all primary care office visits; of these visits, discomfort in the knee, shoulder, and back are the most prevalent musculoskeletal symptoms. Having pain or dysfunction in the front part of the knee is a common presentation and reason for a patient to see a health care provider. There are a number of pathophysiological etiologies to anterior knee pain. This article describes some of the common and less common causes, and includes sections on diagnosis and treatment for each condition as well as key points. PMID:24994047

  13. [Pain and Christianity. A symbol for overcoming pain?].

    Pain and Christianity appear to belong together: Christ's pain stands at the centre of God's healing; his pain leads to the salvation of mankind. We can learn from Jesus' example how to bear suffering and pain. In early Christian times, the belief that Jesus Christ suffered pain on the cross was usually not accepted. In line with the "apathy axiom", freedom from emotion was something to strive for at that time. Only after the acceptance of Christianity as the state religion of the Roman Empire in 380 AD did the pain of Christ again stand in the centre of the Christian doctrine of salvation. The memory of the fact that Jesus himself had to undergo the worst pain can still help people to overcome their pain and comfort them. PMID:17674055

  14. Reward and motivation in pain and pain relief

    Pain is fundamentally unpleasant, a feature that protects the organism by promoting motivation and learning. Relief of aversive states, including pain, is rewarding. The aversiveness of pain, as well as the reward from relief of pain, is encoded by brain reward/motivational mesocorticolimbic circuitry. In this Review, we describe current knowledge of the impact of acute and chronic pain on reward/motivation circuits gained from preclinical models and from human neuroimaging. We highlight emerging clinical evidence suggesting that anatomical and functional changes in these circuits contribute to the transition from acute to chronic pain. We propose that assessing activity in these conserved circuits can offer new outcome measures for preclinical evaluation of analgesic efficacy to improve translation and speed drug discovery. We further suggest that targeting reward/motivation circuits may provide a path for normalizing the consequences of chronic pain to the brain, surpassing symptomatic management to promote recovery from chronic pain.

    Objective: This study aimed at developing an experimental paradigm to assess vicarious pain experiences. We further explored the putative moderating role of observer's characteristics such as hypervigilance for pain and dispositional empathy. Methods: Two experiments are reported using a similar procedure. Undergraduate students were selected based upon whether they reported vicarious pain in daily life, and categorized into a pain responder group or a comparison group. Participants were presented a series of videos showing hands being pricked whilst receiving occasionally pricking (electrocutaneous) stimuli themselves. In congruent trials, pricking and visual stimuli were applied to the same spatial location. In incongruent trials, pricking and visual stimuli were in the opposite spatial location. Participants were required to report on which location they felt a pricking sensation. Of primary interest was the effect of viewing another in pain upon vicarious pain errors, i.e., the number of trials in which an illusionary sensation was reported. Furthermore, we explored the effect of individual differences in hypervigilance to pain, dispositional empathy and the rubber hand illusion (RHI) upon vicarious pain errors. Results: Results of both experiments indicated that the number of vicarious pain errors was overall low. In line with expectations, the number of vicarious pain errors was higher in the pain responder group than in the comparison group. Self-reported hypervigilance for pain lowered the probability of reporting vicarious pain errors in the pain responder group, but dispositional empathy and the RHI did not. Conclusion: Our paradigm allows measuring vicarious pain experiences in students. However, the prevalence of vicarious experiences of pain is low, and only a small percentage of participants display the phenomenon. It remains however unknown which variables affect its occurrence.

    Objective?To examine associations between parental history of pain and catastrophizing and their adolescents pain, somatic symptoms, catastrophizing, and disability.?Methods?Participants included 178 youths aged 1114 years recruited through public schools. Adolescents completed measures assessing pain characteristics, somatic symptoms, and pain catastrophizing. Parents reported on their own pain, and catastrophizing about their adolescents pain.?Results?About one quarter of the adolescents and two thirds of parents reported having pain. Parent pain was associated with adolescent pain, somatic symptoms, and pain catastrophizing. Parent catastrophizing was a significant predictor of adolescent somatic symptoms and pain-related disability, beyond the contribution of parent pain. Adolescent catastrophizing mediated the association between parent catastrophizing and adolescent pain-related disability.?Conclusions?Parent history of pain and pain-related cognitions may contribute to adolescent risk for chronic pain.

  18. Understanding the cancer pain experience.

    Cancer pain management is a major element of successful cancer survivorship. Regardless of where someone is along the cancer experience, from a newly diagnosed patient to long-term survivor, pain is a potential treatment-related effect that can have a significant impact on a survivor's life. Quality pain management for cancer survivors is complicated by the fact that cancer-related pain can be due to the tumor, surgery, radiation, and/or chemotherapy. Additionally, the pain experience is related to many psychosocial/spiritual factors. Despite almost 40 years of attention devoted to improving cancer pain management, many cancer survivors are less than optimally treated, often owing to survivor and healthcare provider knowledge barriers. This article reviews some of the latest research related to cancer pain management treatment options, measurement/assessment, and interventions. Progress has been made in understanding new aspects of the pain experience, but more work is yet to be done. PMID:24925442
