In sheep, the diagnosis of foot lesions is routinely based on physical examination of the hoof. Correct diagnosis is important for the effective treatment, prevention and control of both infectious and non-infectious causes of lameness. Therefore, the aim of this study was to evaluate the level of inter-observer agreement for clinical examination of ovine foot lesions. Eight observers of varying experience, training and occupation performed foot examinations on a total of 1158 sheep from 38 farms across North England and Wales. On each farm, a group of two to four observers independently examined a sample of 24 to 30 sheep to diagnose the presence or absence of specific foot lesions including white line lesions (WL), contagious ovine digital dermatitis (CODD), footrot (FR), inter-digital dermatitis (ID) and toe granuloma (TG). The inter-observer agreement of foot lesion assessments was examined using Fleiss kappa (κ), and Cohen's κ examined the paired agreement between the test standard observer (TSO) and each observer. Scoring differences with the TSO were examined as the percentage of scoring errors and assessed for evidence of systematic scoring bias. With the exception of WL (maximum error rate 33.3%), few scoring differences with the TSO occurred (maximum error rate 3.3%). This suggests that observers can achieve good levels of reliability when diagnosing most of the commonly observed foot conditions associated with lameness in sheep., (Copyright © 2016 Elsevier Ltd.

Soft tissue sarcomas arising in the foot and ankle are often misdiagnosed, resulting in excision without adequate preoperative staging or surgical margins. The goal of the present study was to review a case series of soft tissue sarcomas of the foot and ankle with attention directed at unplanned excisions of sarcomas. An unplanned excision means that a patient either underwent an inadequate preoperative workup or the preoperative workup indicated a benign entity, resulting in surgical resection. We retrospectively analyzed the medical records of 10 patients with sarcomas of the foot and ankle treated at our institution. All soft tissue sarcomas were excised with the widest margin possible without any major bone or neurovascular resection to allow for preservation of the foot. All patients were followed up for a minimum of 8 months to assess pain, function, and complications. The patients were followed up for an average of 22.4 (range 8 to 44) months. Of the 10 patients, 6 had undergone preoperative magnetic resonance imaging without contrast and the sarcomas were read as benign or cystic masses. Two patients had undergone preoperative magnetic resonance imaging with contrast, and these scans were also misread. Despite having undergone previous unplanned surgery, none of these sarcomas had recurred after repeat resection with a wider margin at a mean follow-up of 22.4 (range 8 to 44) months. At the last follow-up point, 8 patients were alive without evidence of disease. Minor complications included lymph edema in 1, stress fracture in 1, and wound infection in 1 that resolved. Preoperative MRI with contrast is recommended before resecting any soft tissue masses of the foot and ankle. In the event of an unplanned excision of a soft tissue sarcoma, the patient should be referred to an orthopedic oncologist for definitive surgery to optimize the oncologic and functional results. In the present retrospective analysis, previous intervention did not seem to affect the prognosis, including local recurrence, distant metastasis, disease-free interval, and functional outcomes., (Copyright © 2016 American College of Foot and Ankle Surgeons.

Viral warts or verruca pedis (plantar warts) are common skin conditions seen in both children and adults. Human papilloma virus (HPV), a DNA virus, is responsible for plantar verrucae. It needs an epidermal abrasion and a transiently impaired immune system to inoculate a keratinocyte. These entities are a therapeutic conundrum for many practitioners. This article discusses HPV infiltration and its subtypes involved in plantar warts; the evaluation of patients with plantar warts; and subsequent treatment options, such as laser, Candida albicans immunotherapy, topical therapy such as phytotherapy, and surgical excision., (Copyright © 2016 Elsevier Inc.

Background: Lameness represents the third most important health-related cause of economic loss in the dairy industry after fertility and mastitis. Although, dairy Mediterranean Buffaloes (MB) and dairy cows share similar breeding systems predisposing to similar herd problems, published studies exploring its relevance and role in these ruminants are still rare and incomplete. The aims of this study were to describe the clinical findings of foot disorders (FDs) in dairy MB and their influence on animal welfare, determined by assessment of locomotion score (LS), body condition score (BCS) and cleanliness score (CS)., Results: Of 1297 multiparous MB submitted to routine trimming procedures, 229 buffaloes showed at least one FD. The prevalence of buffaloes affected by FDs was 17.7 %, while motility and lameness indexes were 84.1 % (1091/1297) and 15.9 % (206/1297), respectively. Overgrowth was present in 17.0 % (220/1297), corkscrew claw in 15.8 % (205/1297), interdigital phlegmon in 0.9 % (12/1297), white line abscess in 0.8 % (11/1297), digital dermatitis in 0.1 % (1/1297) and interdigital hyperplasia in 0.1 % (1/1297). Simultaneous presence of FDs was recorded in 17.0 % of MB (221/1297): overgrowth and corkscrew claw occurred together in 15.8 % of cases (205/1297), overgrowth and interdigital phlegmon in 0.3 % (4/1297), overgrowth and white line abscess in 0.8 % (11/1297), digital dermatitis and interdigital hyperplasia in 0.1 % (1/1297). The presence of FDs was always associated with lameness (LS > 2), except from 23 MB with simultaneous overgrowth and interdigital phlegmon occurrence. The majority of MB within the under-conditioned group (95.5 %, 43/45) and all those with CS > 2 (122/122) had a locomotion score above the threshold of normality (LS > 2). Furthermore, foot diseases such as interdigital hyperplasia, white line abscess and digital dermatitis or interdigital hyperplasia seemed to occur more frequently associated with decreased BCS and increased CS scores., Conclusions: This study describes for the first time the involvement of white line disease, interdigital phlegmona, digital dermatitis and interdigital hyperplasia in foot disorders of dairy Mediterranean buffalo and shows their association with an impairment of animal welfare.

The objective of this study was to evaluate infrared thermography as a noninvasive screening tool for detection of pododermatitis during the developing and active stages of disease in three species of penguins: king penguin (Aptenodytes patagonicus) , macaroni penguin (Eudyptes chrysolophus), and rockhopper penguin (Eudyptes chrysocome). In total, 67 penguins were examined every 3 mo over a 15-mo period. At each exam, bumblefoot lesions were characterized and measured, and a timed series of thermal images were collected over a 4-min period. Three different methods were compared for analysis of thermograms. Feet with active lesions that compromise the surface of the foot were compared to feet with inactive lesions and no lesions. The hypothesis was that feet with active lesions would have warmer surface temperatures than the other conditions. Analysis of the data showed that although feet with active bumblefoot lesions are warmer than feet with inactive or no lesions, the variability seen in each individual penguin from one exam day to the next and the overlap seen between temperatures from each condition made thermal imaging an unreliable tool for detection of bumblefoot in the species studied.

The current report describes the temporary regression, due to intensive symptomatic treatment, of ulcerative skin lesions caused by squamous cell carcinoma in a white rhinoceros. A captive, 40-yr-old southern white rhinoceros (Ceratotherium simum simum) developed profound, ulcerative skin lesions on the pads of both hind feet. At the peak of the disease, at least one quarter of the pads was affected. A diagnosis of squamous cell carcinoma was made via biopsy. Treatment included anti-inflammatory drugs, antibiotics, and local care. The lesions regressed on both feet until they seemed clinically healed. It was presumed that long-term, anti-inflammatory treatment and local bandaging had induced the temporary regression of the lesions. Two years later, however, a small ulcerative lesion reappeared on one pad and post mortem examination confirmed that the carcinoma was also histologically present in the clinically intact tissue. No metastasis was found and computed tomography showed normal digital bones.

Background: Callus is one of the most common foot skin complaints experienced by people of all ages. These painful and unsightly lesions often result in disability. The 'gold standard' of treatment is scalpel debridement by a trained specialist; however, people also seek over-the-counter remedies. There is a lack of clinical evidence for the efficacy of such products, which makes selection by patients and practitioners difficult., Methods: This randomised, three-armed, parallel, comparative trial aimed to test the efficacy of two home treatments for plantar callus using novel, objective outcome measures (skin hydration using the capacitance method; elasticity using negative pressure application; and surface texture using imaging). Additional outcome measures were: size of callus, quality of life (Foot Health Status Questionnaire) and self-reported participant satisfaction and compliance. The results were compared to a podiatry treatment. Participants were randomly allocated to one of three groups: potassium hydroxide (KOH, 40 %); trichloroacetic acid (TCA); and podiatry treatment. Participants were followed for 3 weeks after their initial intervention appointment (days 7, 14 and 21). The primary outcomes were the change from baseline in callus hydration, elasticity, texture, and size at each of the three time points. The secondary outcomes where: change in quality of life 21 days after treatment; resolution of calluses via visual inspection; and participant compliance and perception., Results: Forty-six participants (61 ft) with plantar calluses were recruited. The podiatry treatment showed immediate and significant changes in all objective outcomes, associated foot pain and function (p <0.01). Lesser changes in skin quality and perceived pain and functional benefits occurred with TCA and KOH over 21 days., Conclusions: This is the first study where objective outcome measures have been used to measure changes in the nature of skin in response to callus treatments. We found significant differences in plantar callus in response to podiatry and two home treatments. The podiatry treatment showed immediate and significant changes in skin and associated foot pain and function. Lesser, but sometimes comparable, changes in skin and perceived pain and functional benefits occurred with TCA and KOH over 21 days., Trial Registration: ISRCTN14751843 : date of registration: 30 April 2015.

The objective of this cross-sectional study was to compare the prevalence of selected clinical signs in laminitis cases and non-laminitic but lame controls to evaluate their capability to discriminate laminitis from other causes of lameness. Participating veterinary practitioners completed a checklist of laminitis-associated clinical signs identified by literature review. Cases were defined as horses/ponies with veterinary-diagnosed, clinically apparent laminitis; controls were horses/ponies with any lameness other than laminitis. Associations were tested by logistic regression with adjusted odds ratios (ORs) and 95% confidence intervals, with veterinary practice as an a priori fixed effect. Multivariable analysis using graphical classification tree-based statistical models linked laminitis prevalence with specific combinations of clinical signs. Data were collected for 588 cases and 201 controls. Five clinical signs had a difference in prevalence of greater than +50 per cent: 'reluctance to walk' (OR 4.4), 'short, stilted gait at walk' (OR 9.4), 'difficulty turning' (OR 16.9), 'shifting weight' (OR 17.7) and 'increased digital pulse' (OR 13.2) (all P<0.001). 'Bilateral forelimb lameness' was the best discriminator; 92 per cent of animals with this clinical sign had laminitis (OR 40.5, P<0.001). If, in addition, horses/ponies had an 'increased digital pulse', 99 per cent were identified as laminitis. 'Presence of a flat/convex sole' also significantly enhanced clinical diagnosis discrimination (OR 15.5, P<0.001). This is the first epidemiological laminitis study to use decision-tree analysis, providing the first evidence base for evaluating clinical signs to differentially diagnose laminitis from other causes of lameness. Improved evaluation of the clinical signs displayed by laminitic animals examined by first-opinion practitioners will lead to equine welfare improvements., (British Veterinary Association.)

Objective: To determine, first, if fat mass index (FMI) or fat-free mass index (FFMI) and serum adipokines tumor necrosis factor (TNF) and interleukin-6 (IL-6) are associated with prevalent (stage 2) foot pain, and, second, if they are predictive of future (stage 3) foot pain., Methods: A subset of participants ages ≥50 years (n = 1,462) from the North West Adelaide Health Study were used for this study. Participants from this community cohort were asked in stage 2 (2004-2006) and stage 3 (2008-2010) if they had foot pain, aching, or stiffness. In stage 2, serum adipokines and anthropometry were measured, while body composition was analyzed with dual x-ray absorptiometry. These variables, along with comorbidities and social history, were used in logistic regression analyses to determine if FMI, FFMI, and serum adipokines were associated with foot pain., Results: Prevalent foot pain was present in 20.2% of participants, and future foot pain in 36.4%. Following multivariate modeling, the odds of having pain at stage 2 increased by 8% for each FMI unit (odds ratio [OR] 1.08, 95% confidence interval [95% CI] 1.04-1.12), while the odds of having pain at stage 3 increased by 6% for each FMI unit at stage 2 (OR 1.06, 95% CI 1.02-1.11). TNF level, IL-6 level, and FFMI were not associated with pain., Conclusion: Increased FMI, but not body mass index, FFMI, or TNF or IL-6 level, was associated with both prevalent and future foot pain. These results suggest that body fat may be more important than body weight with respect to foot pain. The role played by other adipokines requires further investigation., (© 2016, American College of Rheumatology.)

Charcot neuropathy is a painless, progressive, degeneration most notably of the ankle or midfoot joints, seen in patients with diabetes and neuropathy. This article will describe the etiology, diagnosis, and treatment of this potentially debilitating joint disease and provide implications for home care clinicians.

We present the case of a patient with a glomus tumor that was atypical because of its large size and histologic characteristics. It was located in the dorsal-distal zone of the fifth ray of the left foot and was associated with a neuroma under the fifth metatarsal head. Although the pain (of a neurologic type) was attributed to the neuroma, the unknown nature and evolution of the dorsal lesion (glomus tumor) made surgical treatment necessary. Surgery, together with compensating treatment of the functional alterations of the patient's feet (pronation of the subastragalar joint, supination of the forefoot, and fifth metatarsal overload syndrome), resolved the case.

Plantar warts can be distinguished from calluses using the squeeze maneuver, a quick and easy method to diagnose plantar warts. This technique negates the need for an expensive diagnostic tool.

Reasons for Performing Study: There are few studies on the correlations between radiographic measurements of the foot and abnormalities of specific structures found with magnetic resonance imaging (MRI)., Objectives: To document the relationship between radiographic measurements of the equine foot and the presence of lesions in the foot on MRI. We hypothesised that different radiographic measurements would be associated with specific lesions detected by MRI., Study Design: Retrospective analysis of radiographs and MRI studies., Methods: Seventy-four feet from 52 lame horses were included. Twenty parameters were measured on radiographs, whereas the signal intensity, homogeneity and size of each structure in the foot were evaluated on magnetic resonance images. The data were analysed using simple linear correlation analysis and classification and regression trees (CARTs)., Results: Linear correlations were found between the navicular bone compacta thickness and injuries of the deep digital flexor tendon, collateral sesamoidean ligament, navicular spongiosa and navicular bone proximal border. Long-toed horses had a high incidence of lesions involving the spongiosa and proximal border of the navicular bone. Elongation of the navicular bone was associated with proximal and distal border injuries. A reduced palmar angle and increased angle between the middle and distal phalanx were observed in horses with alterations of collateral ligaments of the distal interphalangeal joint and navicular bone spongiosa, respectively. For each structure under investigation, CARTs predicting the presence of MRI pathology based on radiographic measurements had excellent performance, with >80% correct classification of cases, when using one of 3 data sources., Conclusions: This study demonstrated a relationship between radiographic measurements of the foot and the presence of lesions detected on MRI, while CARTs illustrated that different radiographic measurements were associated with different MRI lesions., (© 2015 EVJ Ltd.)

The use of inserts and orthopedic shoe adjustment represents an essential component of the conservative therapy of degenerative diseases and deformities of the musculoskeletal system. Inserts can have supportive, bedding and corrective effects and are used in particular for complaints of the feet and ankles. The combination of diverse materials allows a high level of cushioning and supporting features and corresponding longevity to be accomplished. The production is carried out on an individual basis and if necessary computer-assisted in order to achieve an optimal fit. For severe and rigid deformities the formation of pressure ulcers can be prevented by orthopedic shoe adjustment and by the use of orthopedic tailor-made shoes.

Cutaneous larva migrans syndrome is a subcutaneous dermatitis caused by hookworms' larvae, originating from animals in parasitic impasse in humans. Transcutaneous infestation is favored by contact with contaminated soil. We report the case of a 15-month-old child, native of Guinea - Bissau, suffering from cutaneous larva migrans syndrome on a malformed foot. This malformation in the form of a syndactyly, associated with a tumefaction of the foot cause a delay in the standing position. Besides, the fact that the child never wears shoes because of the sick foot is another factor contributing to the patient's infestation by the larvae of the nematode.

Unlabelled: Tumors of the foot and ankle are rarely encountered in the general patient population. Even among studies of tumor patients, foot and ankle neoplasms are uncommon. Given the weight-bearing demands of the foot and its relatively small area, even small masses are likely to be symptomatic and/or palpable to both patient and physician. Only 3% of osseous neoplasms are found in this region, while 8% of benign soft tissue tumors and 5% of malignant soft tissue tumors are localized to the foot and ankle. Despite the rarity of presentation, it is important for orthopaedic surgeons to be familiar with the diagnostic criteria and therapeutic options for these patients, as each tumor varies in its presentation, level of aggressiveness, and natural history of the disease. With appropriate diagnostic tests and treatment, patients can anticipate a reasonable chance of survival and preservation of function. In this review article, the authors survey the current literature regarding the presentation, diagnostic workup, and treatment for the most common benign and malignant tumors of the foot and ankle., Levels of Evidence: Level IV: Literature Review., (© 2015 The Author(s).)

Background: Feet are often the first site of joint involvement in rheumatoid arthritis (RA) and get progressively worse if unmanaged, leading to permanent disability and negatively impacting patients' quality of life. Podiatrists are specialists in the assessment, diagnosis and management of foot and ankle problems, however, RA outpatients often rely on referral from rheumatology clinicians to gain access to musculoskeletal podiatry services on the UK National Health Service (NHS). Therefore, the aim of this evaluation was to identify the foot health needs of rheumatoid arthritis patients and if they are being met by rheumatology clinicians., Methods: A mixed methods approach was used: collecting qualitative data from patients and quantitative data from clinicians. Two focus groups were conducted with nine RA patients from a tertiary rheumatology outpatient clinic in the UK and the data were thematically analysed to inform a clinician survey. Thirteen rheumatology clinicians, from the same centre, completed the online survey. Resultant data were analysed to produce descriptive statistics., Results: Patient focus group data generated four main themes: (1) need for foot health information, (2) feet ignored during routine consultations, (3) frequency of foot examination and (4) access to podiatry. Survey data highlighted that (i) 69-85 % of clinicians provided patients with foot health information sometimes, (ii) feet were examined in 47 % of routine consultations, (iii) 54 % of clinicians did not examine feet routinely because they are not included in the disease activity score with 28 joints (DAS-28), (iv) 31 % of clinicians referred patients to podiatry upon RA diagnosis, (v) 0 % of clinicians referred patients to podiatry for periodic review, (vi) 54 % of clinicians believed patients will self-report foot problems and (vii) 62 % of clinicians felt competent in foot examination., Conclusions: RA patients' foot health needs were not being fully met by rheumatology clinicians. Patients want foot health information and easy access to podiatry services. Rheumatology outpatient consultations need to have a wider focus than the DAS-28 and incorporate foot examination as standard. Clinicians need to ensure they have sufficient training and follow current national foot health guidance to provide optimal foot health care and outcomes for their RA patients.

A 73-year-old woman presented at the Surgery department with a swelling at the base of the toe nail of her left hallux, 20 years after partial wedge resection because of onychocryptosis. We removed the swelling surgically. Histological examination of the tissue revealed a traumatic epithelial cyst.

Objective: The aim of this study was to assess the validity of the Integrated Management of Childhood Illness (IMCI) algorithm to detect edematous type of malnutrition in Egyptian infants and children ranging in age from 2 months to 5 years., Materials and Methods: This study was carried out by surveying 23 082 children aged between 2 months and 5 years visiting the pediatric outpatient clinic, Ain Shams University Hospital, over a period of 6 months. Thirty-eight patients with edema of both feet on their primary visit were enrolled in the study. Every child was assessed using the IMCI algorithm 'assess and classify' by the same physician, together with a systematic clinical evaluation with all relevant investigations., Results: Twenty-two patients (57.9%) were proven to have nutritional etiology. 'Weight for age' sign had a sensitivity of 95.5%, a specificity of 56%, and a diagnostic accuracy of 78.95% in the identification of nutritional edema among all cases of bipedal edema. Combinations of IMCI symptoms 'pallor, visible severe wasting, fever, diarrhea', and 'weight for age' increased the sensitivity to 100%, but with a low specificity of 38% and a diagnostic accuracy of 73.68%., Conclusion and Recommendations: Bipedal edema and low weight for age as part of the IMCI algorithm can identify edema because of nutritional etiology with 100% sensitivity, but with 37% specificity. Revisions need to be made to the IMCI guidelines published in 2010 by the Egyptian Ministry of Health in the light of the new WHO guidelines of 2014.

Background: Morton's neuroma is a common cause of inter-metatarsal foot pain. Surgical excision is generally indicated when non-operative measures have been unsuccessful; various surgical techniques have been described in the literature for excision, with no consensus on the overall ideal surgical approach., Aim: To assess patient outcomes and complications following plantar surgical approach to neurectomy in a consecutive series of patients., Method: An analysis of consecutive patients undergoing excision of Morton's neuroma using a plantar approach by a single surgeon over a 12 month period. Pre- and post-operative AOFAS and VAS scores were completed during outpatient visits., Results: 20 patients were included in the study, with pre-operative confirmation of a soft tissue mass on ultrasound scan. All patients demonstrated improvement in their post-operative functional scores; 2 patients (10%) did not have full resolution of their symptoms post-operatively. Mean AOFAS scores improved from 39 to 80 post-operatively and VAS from 40 to 92. No patients had wound complications or scar pain., Conclusion: Neurectomy performed via a plantar approach provides good exposure, adequate soft tissue healing, with rapid resolution of pain and return to normal activities post-operatively., (Copyright © 2015 Elsevier Ltd.

Background: Extraskeletal myxoid chondrosarcoma is a rare tumor with an indolent course, high propensity for local recurrence, metastases, and propensity for the proximal extremities of middle-aged males., Case Report: We present the case of a 44-year-old man with an extraskeletal myxoid chondrosarcoma in the plantar fascia of the medial arch initially thought to be a plantar fibroma. Magnetic resonance imaging of the lesion demonstrated a lobulated subcutaneous mass plantar to the tarsal bones and inseparable from the fascia. Microscopic examination revealed a lobulated lesion composed of cords and nests of round to spindled malignant cells in a blue-gray myxoid matrix surrounded by fibrous septae. The malignant cells displayed variable positivity for S-100., Conclusion: Plantar extraskeletal myxoid chondrosarcoma is a rare occurrence. It should always be considered in the differential diagnosis of masses arising in the plantar fascia of the foot., (Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

Background: The ideal treatment for juvenile osteochondritis dissecans of the talus (ODT) is still unclear. To determine predictors of failure of conservative treatment, children admitted for ODT were retrospectively analyzed., Methods: Patient files were analyzed to search for children treated for an ODT between 2000 and 2011. X-rays and MRI at baseline were evaluated for grading of lesions and the patient history was obtained. Final follow-up evaluation was performed via questionnaire and complementary telephone interview. Outcome was measured using the AOFAS and the Olerud/Molander scores. Conservative treatment consisted of out of sports and modification of activity under full weight-bearing. In case of persisting pain, full load removal on crutches was initiated. For further analysis, two groups were formed: (1) successful conservative treatment; (2) converted to surgical therapy. A logistic regression was used to determine potential predictors of conservative treatment failure., Results: Seventy-seven lesions in 67 children with a mean age of 11.4 years (range 4-15 years) at the time of diagnosis were identified. Every patient received conservative treatment as a first-line treatment after diagnosis of ODT except for one single patient with a grade IV lesion at time of diagnosis who received operative treatment directly after diagnosis. Sixty-one percent of the lesions failed conservative treatment. A higher age as well as a grade III lesion at time of diagnosis was predictive for failure of the conservative treatment (p = 0.03 and p = 0.02, respectively). Regarding the functional outcome, a higher grade lesion in general was predictive for an inferior outcome as measured by clinical score., Conclusion: Grade III ODT especially in older children leads significantly more often to treatment failure when treated non-surgically. No other predictors for treatment failure could be identified., Level of Evidence: Level III (retrospective comparative study).

Background: Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare syndrome consisting of acute symmetrical tenosynovitis of the hands and wrists associated with pain and marked pitting edema of the dorsum of the hands or the feet. Persistent rheumatoid factor seronegativity and elevated acute phase reactants are the rule, while radiographic findings are characterized by the absence of bony erosions. The syndrome has occasionally been associated with a wide range of diseases including solid and hematological malignancies, polymyalgia rheumatica, and other inflammatory rheumatic diseases., Methods: Two patients with skin eruption on hands and feet associated with arthromyalgias have been investigated to confirm diagnosis of RS3PE and to detect comorbidities. A revision of all the possible medical conditions correlated to RS3PE has been performed., Results: We report two cases of RS3PE associated with Parvovirus B19 infection/reactivation. There are very few reports on the association between RS3PE and infectious agents, and in only one case the syndrome has been correlated to parvovirus infection., Conclusions: We want to underline the importance for patients with RS3PE to be seen by dermatologists who should become familiar with this syndrome and remark that Parvovirus B19 infection may be a potential cause of RS3PE., (© 2015 The International Society of Dermatology.)

Symptoms: A patient presented suffering from neural pain in the medial foot for a period of over 20 years., Diagnosis: Diagnostic showed a widely spread soft-tissue tumor consisting of confluent glomuvenous malformations that was responsible for the immense pain syndrome.The solitary or multiform-appearing knots are not compressible and manifest as the characteristic syndromes of regional pain, sensitivity to coldness, or local pressure pain. Alternatively, the patient could also be completely symptom-free., Treatment: Because of the dimension of the tumor and the degree of suffering, a radical resection with simultaneous microsurgical reconstruction was carried out. Twelve weeks postoperatively, healing of the flap stabilized, the foot is fully weight-bearing, and the patient is pain-free.

Plantar pain is a common problem endured by most adults at some point in their life that may result in considerable disability. Plantar fibromatosis is a locally invasive neoplasm, with the development of fibrous nodules on the plantar aspect of the feet, which can remain asymptomatic for years. (18)F-Fluorodeoxyglucose ((18)F-FDG) PET/CT has been more prevalent as the imaging modality of choice for cancer patients, but the imaged field of view is often from the base of the skull to the upper thighs. Therefore, the feet are typically not included in the field. However, true whole-body imaging from the top of the skull to the bottom of the feet is performed at some institutions and can provide clinically useful findings. One such finding is the presence of (18)F-FDG-avid plantar nodules. This review is intended to help clinicians become aware of these potential false-positive nodules that can affect a patient's staging and management.

Foot pathologies can negatively influence foot function, consequently impairing gait during daily activity, and severely impacting an individual's quality of life. These pathologies are often painful and correspond with high or abnormal plantar pressure, which can result in asymmetry in the pressure distribution between the two feet. There is currently no general consensus on the presence of asymmetry in able-bodied gait, and plantar pressure analysis during gait is in dire need of a standardized method to quantify asymmetry. This paper investigates the use of plantar pressure asymmetry for pathological gait diagnosis. The results of this study involving plantar pressure analysis in fifty one participants (31 healthy and 20 with foot pathologies) support the presence of plantar pressure asymmetry in normal gait. A higher level of asymmetry was detected at the majority of the regions in the feet of the pathological population, including statistically significant differences in the plantar pressure asymmetry in two regions of the foot, metatarsophalangeal joint 3 (MPJ3) and the lateral heel. Quantification of plantar pressure asymmetry may prove to be useful for the identification and diagnosis of various foot pathologies.

Charcot neuropathic osteoarthropathy (CN) is a progressive disease affecting the bones, joints and soft tissue of the foot and ankle, most commonly associated with diabetic neuropathy. Patients with diabetes complicated by CN have especially high morbidity, frequency of hospitalisation, and therefore, significant utilisation of expensive medical resources. The diagnosis of early CN can be challenging and is based on clinical presentation supported by various imaging modalities. Imaging is important for the detection of early CN and is useful in monitoring progression and complications of the disease. The later stages of CN are potentially devastating for individuals and present an increasing socioeconomic challenge for health systems. The astute radiologist, particularly in the context of a multidisciplinary team, plays a critical role in diagnosis of the primary disease and its complications. This review article aims to outline the key features of CN, emphasising current clinical and radiologic concepts as an aid for the practising radiologist., (© 2015 The Royal Australian and New Zealand College of Radiologists.)

Objectives: To compare ultrasound (US) and magnetic resonance imaging (MRI) in the diagnosis of Morton's neuroma., Methods: Studies that assessed the diagnostic accuracy of US and MRI for Morton's neuroma were retrieved from major medical libraries independently by two reviewers up to 1 April 2014. Predefined inclusion and exclusion criteria were adopted., Results: 277 studies were initially found, and the meta-analysis was conducted on 14 studies. US sensitivity was studied in five studies, MRI sensitivity in three studies, and bothin six studies. All studies used surgery as the reference standard. A high sensitivity (SE) of diagnostic testing was observed for both US (SE (95 % CI) = 0.91 (0.83-0.96)) and MRI (SE (95 % CI) = 0.90 (0.82-0.96)) with no significant differences between the two modalities in diagnosis (Q test p = 0.88). For MRI, specificity of test was 1.00 with a pooled estimation of 1.00 (0.73-1.00), while the pooled specificity was 0.854 (95 % CI: 0.41-1.00) for US. No differences were observed between US and MRI in study design (p = 0.76)., Conclusion: This meta-analysis shows that the SE of US (0.91) is equal to (p = 0.88) that of MRI (0.90) for identification of Morton's neuroma., Key Points: • For Morton's neuroma, US sensitivity is equal to MRI. • US is as accurate as MRI in diagnosing Morton's neuroma. • US may be the most cost-effective imaging method for Morton's neuroma.

Epithelioid sarcoma-like hemangioendothelioma (ES-H) is a rare, indolent vascular neoplasm with characteristics similar to epithelioid sarcoma. It typically affects young males who present with skin and subcutaneous lesions in the extremities. Bone lesions, occurring in approximately 20% of patients, are often multifocal, seen in conjunction with soft tissue lesions, and usually found in bones of the lower extremities. This report details the case of a 20-year-old male who presented with a 1-year history of painful skin lesions on his left lower extremity. Staging studies revealed bone lesions in the cuboid and calcaneus. Bone and soft tissue pathology was consistent with ES-H. The soft tissue lesions were treated with wide excision and the bony lesions with radiofrequency ablation (RFA). The patient had no evidence of recurrence at the 2-year follow-up. Treatment of ES-H typically consists of wide excision of all soft tissue lesions and possible adjuvant radiation therapy. Management of bony lesions has included marginal excision, wide excision, amputation, chemotherapy, observation, or a combination of these modalities. ES-H has the potential for distant metastases. There is no consensus regarding the appropriate treatment of multifocal epithelioid sarcoma-like hemangioendothelioma involving bone. A potential treatment strategy of wide excision of soft tissue lesions and RFA of bone lesions is proposed.

The aim of the present study was to assess the diagnostic accuracy of 7 clinical tests for Morton's neuroma (MN) compared with ultrasonography (US). Forty patients (54 feet) were diagnosed with MN using predetermined clinical criteria. These patients were subsequently referred for US, which was performed by a single, experienced musculoskeletal radiologist. The clinical test results were compared against the US findings. MN was confirmed on US at the site of clinical diagnosis in 53 feet (98%). The operational characteristics of the clinical tests performed were as follows: thumb index finger squeeze (96% sensitivity, 96% accuracy), Mulder's click (61% sensitivity, 62% accuracy), foot squeeze (41% sensitivity, 41% accuracy), plantar percussion (37% sensitivity, 36% accuracy), dorsal percussion (33% sensitivity, 26% accuracy), and light touch and pin prick (26% sensitivity, 25% accuracy). No correlation was found between the size of MN on US and the positive clinical tests, except for Mulder's click. The size of MN was significantly larger in patients with a positive Mulder's click (10.9 versus 8.5 mm, p = .016). The clinical assessment was comparable to US in diagnosing MN. The thumb index finger squeeze test was the most sensitive screening test for the clinical diagnosis of MN., (Copyright © 2015 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

We describe how the combination of imaging and histologic findings was essential in establishing a preoperative diagnosis of an extremely rare malignant granular cell tumor (GrCT) occurring in the lower extremity of a 17-year-old man. Magnetic resonance imaging demonstrated a large infiltrative tumor of heterogeneous intermediate signal intensity on both T1- and T2-weighted sequences. Subsequent computed tomography (CT) and fluorodeoxyglucose positron emission tomography CT scans of the patient revealed distant nodal and skeletal metastases., (Copyright © 2015 Elsevier Inc.

Introduction: The Charcot foot (CF) consists of a progressive deterioration of the bones and joints, most common in diabetic patients with advanced neuropathy. The great problem is that can be confused with other processes, delaying the diagnosis and specific treatment. The aim is to analyze the cases of CF diagnosed in our hospital and especially to highlight the role of the general surgeon., Material and Methods: Retrospective study of all registered cases diagnosed of CF between the diabetic population of our Department of Health. A review of the literature was performed., Results: From 2008 to 2012, there 7 cases of CF were diagnosed (prevalence 1:710). Two of the patients were diagnosed erroneously of cellulitis. The average time of delay in the diagnosis was 10 weeks (minimum 1, maximum 24). The initial treatment was immobilization of the extremity. Once the edema was eliminated, an offload orthesis was placed according to Sanders's anatomical classification. Evolution was favorable in 5 patients, 1 patient needed amputation, and other one died of acute cardiac pathology., Conclusions: The CF is a more frequent pathology than we believe. The general surgeon is the fundamental prop in the diagnosis and initial treatment. Before the presence of inflammation and edema of the foot in a patient with diabetes and severe neuropathy, once cellulitis, osteomyelitis, and TVP are ruled out, Charcot neuroarthropathy should be considered., (Copyright © 2013 AEC.

Background: Foot pain is highly prevalent in older people and in many cases is associated with inappropriate footwear. This study evaluated the effectiveness of off-the-shelf, extra-depth footwear in reducing foot pain., Methods: Community-dwelling older people with disabling foot pain (72 men and 48 women aged 65 to 96 years; mean age 82 [SD 8]) were randomly allocated to an intervention group (n = 59) or control group (n = 61). The intervention group was provided with off-the-shelf, extra-depth footwear. Participants in the control group received their footwear at the completion of the study. Both groups continued to receive usual podiatry care for the study period. The primary outcome measure was the Foot Health Status Questionnaire (FHSQ), measured at baseline and 16 weeks., Results: There was a significant improvement in the FHSQ pain domain (ANCOVA-adjusted mean difference 11.5 points, 95% confidence interval 4.2 to 18.8, p = .002) and FHSQ function domain (10.0 points, 0.9 to 19.1, p = .032) in the intervention group compared to the control group. The intervention group also developed fewer keratotic lesions (mean difference -1.4, -2.5 to -0.2, p = .021), were less likely to report the use of co-interventions (relative risk [RR] 0.74, 0.56 to 0.98, p = .026) and were more likely to report that their foot pain had moderately or markedly improved during the study (RR = 7.93, 2.51 to 25.00, p < .001; number needed to treat = 3, 2 to 5)., Conclusions: Off-the-shelf, extra-depth footwear significantly reduces foot pain, improves foot function and is associated with the development of fewer keratotic lesions in older people., (© The Author 2014.
