Podiatric conditions observed in Special Olympics athletes: Contrasting data from a USA versus an international population

OBJECTIVES

Persons with intellectual disabilities frequently have podiatric conditions. Findings from the 2018 United States Summer games (USA) venues are compared to those from athletes screened at the 2019 Special Olympics World Summer Games in Abu Dhabi, United Arab Emirates (UAE).

METHODS

Data from Fit Feet screenings from 2445 United Arab Emirates (UAE) participants were compared to 1244 US participants.

RESULTS

A sampling of results that reflect significant differences in findings between the USA cohort and Abu Dhabi cohort include ankle joint range of motion, excessive abduction, hallux abducto valgus and pes planus. The overall shoe to foot mismatch was found to be 52.2%. A professional referral was recommended 27.7% of the time in the USA data and 28.5% in the Abu Dhabi data. An urgent referral was requested 5.1% of the time for the USA data and 3.7% of the time in the Abu Dhabi data.

CONCLUSION

Special Olympics athletes experience a greater prevalence of identifiable podiatric conditions as compared to the general population. Several of the conditions investigated in this study differed significantly between the international Special Olympics cohort and the USA cohort. Assessment of the feet of Special Olympics athletes can help to better appreciate the podiatric conditions in a population of individuals with intellectual disabilities. The variance identified between populations of Special Olympics athletes may be a reflection on the lack of standardization of conditions that are assessed for as well as the disparate characteristics of the clinical volunteers. Future Fit Feet events may wish to consider significant improvements in objectivity and standardization as it pertains to the conditions that are evaluated for in the Fit Feet exam.

An abattoir study of the prevalence of foot lesions and claw measurements in water buffalo in Egypt

BACKGROUND

Lameness has been associated with compromised animal welfare and reduced productivity in dairy cattle herds worldwide. However, little is known about the prevalence of claw lesions in the dairy buffalo population in Egypt. Furthermore, the optimum measurements for claw trimming in buffalo are unknown. A cross-sectional cadaver study was conducted where 135 pair buffalo hind feet were collected from 4 slaughterhouses and examined for the presence of claw lesions. The proportion and associated 95% confidence interval (CI) of each type of lesion were calculated. A separate set of healthy claws (n = 26) underwent ultrasonography (US) and computed tomography (CT). The agreement between US and CT measurements was assessed using Passing-Bablok regression and intraclass correlation coefficient. The CT measurements were used to calculate trimming recommendations.

RESULTS

At least one lesion was identified in 242 claws (89.6%, 95% CI = 85.4-93.0). In healthy claws, poor to moderate agreement was identified between US and CT measurements which could be due a sample size of the study. The average ± standard deviation (SD) minimum recommended external wall length of the lateral and medial claws in heifers was 7.1 ± 0.36 cm and 7.5 ± 0.35 cm, respectively. The average ± SD minimum recommended external wall length in buffaloes over five years of age was 8.2 ± 0.27 cm and 8.4 ± 0.39 cm for the lateral and medial claws, respectively.

CONCLUSIONS

The study found a high prevalence of claw lesions in buffalo in Egypt, the clinical significance of which requires further elucidation. Recommended measurements will help guide claw trimming in buffalo to minimise lesions.

Predictive factors for foot pain in the adult population

BACKGROUND

Foot pain has been associated to factors like: fat, body mass index, age increased, female gender and the presence of pathologies. Although evidence is limited. The purpose is to determine the predictive factors for foot pain in the adult population.

METHODS

From January to December 2021, 457 patients were > 18 years, gave signed informed consent to take part to this cross sectional study. All completed demographic data and various questionnaires related to pain: Foot Function Index, EuroQoL-5D and Visual Analogue Scale (foot pain). Anthropometric measurements were obtained using McPoil platform and foot posture was assessed by the Foot Posture Index (FPI). To determine whether a volume change is a predictive factor for foot pain, a parameter was established: the volumetric index for footwear (VIF). Factors linked to the presence of pain, including the considered VIF variables, were analyzed through multivariable logistic regression.

RESULTS

Among the study population, 40.7% were male and 59.3% female. The mean age of 39.06 years and a body mass index of 25.58 Kg/cm2. The logistic regression model had a classification capability of 72.4%, a sensitivity of 72.3% and a specificity of 73%, in which, the predictors considered were the variables found to have a significant association with FFI-pain > 45 points,, showed that younger women, with a higher BMI, higher values of right FPI (pronation), poorer overall perceived health and with problems in walking were more likely to experience foot pain.

CONCLUSION

Predictive factors for foot pain in the adult population include gender, age, Body Mass Index, FPI on the right foot, perceived health and mobility. Clinical implication, the presented measure aids physicians in assessing their patients´ foot pain likelihood.

Routine hoof-trimming data provides insight into the occurrence of claw lesions in Holstein herds in the central region of South Africa

Claw lesions in dairy cows contribute significantly to lameness, causing distress and discomfort for affected cows and raising welfare concerns. Despite increased awareness, lameness incidence continues to rise. Defining and recording claw traits are particularly problematic. In South Africa (SA), claw data is limited to paper-based records kept by private hoof trimmers. This research analysed claw-trimming data from five dairy farms over 6 years to examine the occurrence and recording of claw lesions in SA Holstein cattle. Lesion identification followed the Claw Lesion Identification in Dairy Cattle brochure. Among the recorded lesions, digital dermatitis (DD) had the highest prevalence (64.02%), followed by sole ulcers (SU; 8.59%), white line disease (WLD; 6.27%), and sole haemorrhage (SH; 4.28%), and most lesions occurred in the rear feet. Chi-square tests and correspondence analysis (CA) were employed to explore the relationships between lesions, feet, and housing. Results indicated that the prevalence of SU and SH showed high similarity for foot and lesion association, and that these were more highly associated with the rear feet. Additionally, the prevalence of DD and interdigital phlegmon were strongly associated, and closely associated with SU, and all these lesions were associated with both dirt lot and free-stall housing systems. CA further confirmed a close association between WLD and SH, and the prevalence of these lesions in the combination housing system. Results of this study highlight the complexity of lesion data and that specific associations between lesions could lead to simplifying the recording thereof. Consolidating the most informative claw lesions into categories will aid in the practical prevention, management, and treatment of lameness on-farm.

Investigating the effect of prophylactic claw trimming on the interval between calving and first observed elevated locomotion score in pasture-based dairy cows

AIMS

To evaluate, in a pasture-based dairy herd, the response to a three-time point hoof trimming regime on lameness incidence and time from calving to observation of an elevated locomotion score (LS).

METHODS

This study was conducted on a 940-cow spring-calving herd in New Zealand's North Island between May 2018 and May 2019. Cows (n = 250) were randomly allocated to the hoof trimming group, with the remainder assigned to the non-trim cohort. One trained professional hoof trimmer used the five-step Dutch method to trim the hind feet of the trimming group. Throughout the subsequent production season, the whole herd was locomotion-scored fortnightly using the 4-point (0-3) Dairy NZ lameness score. Kaplan-Meier survival curves were used to assess the univariable effect of trimming on the interval between calving and first LS of ≥ 2 and first LS ≥ 1. A multivariable Cox proportional hazards regression was used to further evaluate the effect of trimming on time to elevated LS.

RESULTS

Mean lameness (LS ≥ 2) prevalence was 2.6%, with 30% of cows having ≥ 4 observations during the study period when at least one LS was ≥ 2. For LS ≥ 1, mean prevalence was 40%, with 98.6% of cows having ≥ 4 observations during the study period when at least one LS was ≥ 1 during lactation. Hoof trimming had no apparent effect on the incidence of clinical lameness (LS ≥ 2) (trimmed vs. non-trimmed: 33.2% vs. 28.8%, respectively), but for LS ≥ 1, there was a small decrease in the incidence of LS ≥ 1 (trimmed vs. non-trimmed: 96.9% vs. 99.3%, respectively). The hazard of a cow having a first observed LS ≥ 2 in the control group was 0.87 (95% CI = 0.66-1.14) times that of the trimmed group; however, the hazard of a cow having a first LS ≥ 1 was 1.60 (95% CI = 1.37-1.88) times higher in the control than in the trimmed group.

CONCLUSION AND CLINICAL RELEVANCE

On this farm, prophylactic hoof trimming had no clinically relevant impact on the incidence of clinical lameness and was not associated with clinically beneficial reductions in time to first observed LS ≥ 2. This may be because claw horn imbalance was not pronounced on this farm, with 53% of cows needing no trim on either hind limb on the first trimming occasion. Further research on the response to prophylactic trimming in pasture-based dairy cattle is required.

Clinical and Diagnostic Characteristics of Calcaneal Apophysitis: A Systematic Review and Thematic Analysis

BACKGROUND

Calcaneal apophysitis is an overuse injury in pediatric patients that causes heel pain and reduction in function. The aim of this study is to explore this condition and offer medical insight into its presentation and symptomatology, along with current treatment options.

METHODS

We explored PubMed/Medline for studies involving calcaneal apophysitis in pediatric patients. The search included all articles published from database inception until June 1, 2021. We only included articles published in English. Clinical information and demographics extracted from the reported studies were analyzed and assessed.

RESULTS

Only 28 studies met our criteria, with a total of 1,362 cases. Of the cases reported, 973 affected boys (71.4%). Presentation was bilateral in 589 cases (43.2%) and unilateral in 433 cases (31.8%). Radiographic imaging was used for the diagnosis of 358 cases (26.3%). All reported treatment modalities were conservative, and these included physical therapy and rest, kinesiotherapy and taping, and orthotic devices. A total of 733 cases (53.7%) reported improved outcomes,32 cases (2.3%) reported no improvement, and the remainder of cases did not report prognostic outcomes (44%).

CONCLUSIONS

Calcaneal apophysitis is an overuse disease commonly found in the pediatric population. Educating parents and coaches with regard to its symptomatology, etiology, and treatment is essential to diagnose the condition earlier and provide better outcomes.

The prevalence of foot health problems in people living with a rheumatic condition: a cross-sectional observational epidemiological study

This study aimed to determine the prevalence of foot health problems in people living with any rheumatic condition and explore potential associations with exposure variables. A cross-sectional observational epidemiological design was applied. The participants were recruited from one regional patient association in southwest Finland. The data were collected in January-February 2019 and included the Self-reported Foot Health Assessment Instrument (S-FHAI) and demographic questions. In total, 495 responses were obtained. Overall, participants had many foot problems. The point prevalence of self-reported foot problems was 99 per 100 people living with a rheumatic condition. The most prevalent problems were foot pain (73%), dry soles (68%), thickened toenails (58%) and cold feet (57%). Lower educational attainment, increased amount of daily standing and accessing medical or nursing care for foot problems were associated with poorer foot health. The results reveal a high frequency of foot pain among people with rheumatic conditions. The study highlighted the importance of person-centred care and the biological focus that underpins and impacts foot health (what we understand, what we do, and our health-seeking behaviour). Interventions to promote biopsychosocial approaches to personalised foot care could advance people's readiness, knowledge and skill to care for their own feet.

Lesions found at foot trimming of dairy goats: Baseline data for comparing lesions and locomotion scoring

Data on the foot lesions of housed dairy goats, especially those that are not lame, is sparse. In this study, visits were made to four farms for whole herd locomotion scoring after milking and to observe routine foot trimming. During trimming, the amount of trimming required for each hoof was recorded, alongside the presence of lesions. The process was repeated at the next routine foot trim on three of the four farms (on Farm 1 whole herd locomotion scoring after milking was not feasible). Across both visits, 3445 locomotion scores were recorded, alongside 3850 trimming and lesion records. There were large differences between farms and visits in the proportion of lame goats (6.7 to 25.5%) and in the proportion of goats which needed a substantial trim of all four feet (15.1-33.1%). Hoof lesions were observed in 65.5% of trimmed goats. We defined lesions by their site and presence of separation and/or granuloma, with white line separation being the most commonly recorded lesion (41.5% of goats). On all visits on the three farms which were locomotion scored, the number of goats recorded as lame was lower than the number observed with white line lesions, but the relative proportion ranged from 17% to 95.4%. Separations were much more common than granulomas, as granulomas were usually accompanied by separation. Toe lesions were much more likely to be associated with granulomas than white line lesions, with 91.5% of toe separations having granulomas but only 10.6% of white line separations. This study provides useful baseline data for comparing lesions and locomotion scoring between goat herds but also identifies areas where we need more data and more consensus.

Comparison of claw horn disruption lesions in four dairy herds using two different trimming techniques: A case study

Claw disorders are a major problem for health, welfare, and economy in dairy production. This retrospective observational study investigated the association between cow-level prevalence of claw horn disruptive lesions and two different trimming methods - the traditional Danish Method (DAM) and the White Line Atlas Method (WLAM). Trimming records from four herds in Denmark over a 4-year period were analysed. Within each herd, claw trimming was performed with the WLAM for the first 2 years, and the DAM for the next 2 years. The data comprised 3316 claw trimmings of 1027 cows with the WLAM and 3898 claw trimmings of 1080 cows with the DAM. The association between claw trimming method and claw lesions was determined using binominal logistic analysis. There were significant differences between trimming methods for sole haemorrhage (odds ratio = 0.44), sole ulcer (odds ratio = 0.42), and white line separation (odds ratio = 0.64), with a lower prevalence during the period of trimming with the WLAM. No significant difference between trimming methods could be found in the occurrence of white line abscess or double sole. The lower prevalence of claw horn disruption lesions found in this study when cows were trimmed with WLAM justifies and necessitates further experimental studies of claw trimming methods to validate these findings.

Social determinants of diabetes-related foot disease among older adults in New South Wales, Australia: evidence from a population-based study

BACKGROUND

Diabetes-related foot is the largest burden to the health sector compared to other diabetes-related complications in Australia, including New South Wales (NSW). Understanding of social determinants of diabetes-related foot disease has not been definitive in Australian studies. This study aimed to investigate the social determinants of diabetes-related foot disease in NSW.

METHODOLOGY

The first wave of the 45 and Up Study survey data was linked with NSW Admitted Patient Data Collection, Emergency Department Data Collection, and Pharmaceutical Benefits Scheme data resulting in 28,210 individuals with diabetes aged 45 years and older in NSW, Australia. Three outcome variables were used: diabetes-related foot disease (DFD), diabetic foot ulcer (DFU), and diabetic foot infection (DFI). They were classified as binary, and survey logistic regression was used to determine the association between each outcome measure and associated factors after adjusting for sampling weights.

RESULTS

The prevalence of DFD, DFU and DFI were 10.8%, 5.4% and 5.2%, respectively, among people with diabetes. Multivariate analyses revealed that the common factors associated with DFD, DFU and DFI were older age (75 years or more), male, single status, background in English speaking countries, and coming from lower-income households (less than AUD 20,000 per year). Furthermore, common lifestyle and health factors associated with DFD, DFU, and DFI were low physical activity (< 150 min of moderate-to-vigorous physical activity per week), history of diabetes for over 15 years, and having cardiovascular disease.

CONCLUSION

Our study showed that about 1 in 10 adults with diabetes aged 45 years and older in NSW reported DFD. Interventions, including the provision of related health services aimed at reducing all forms of DFD in NSW, are recommended to target older individuals with a long history of diabetes, and coming from lower-income households.

Are mosque carpets' reservoirs for fungi causing superficial foot mycosis? A cross-sectional study in Riyadh, Saudi Arabia

The possibility of superficial foot mycoses to spread through contaminated mosque carpets between worshipers imposes a great health burden and is never addressed in Riyadh, SA. We aimed to assess the prevalence of fungal infections, especially human dermatophytosis acquired from mosque carpets, in five different regions of Riyadh, Saudi Arabia and establish a means of contamination control. A cross-sectional study of 100 mosques in Riyadh, Saudi Arabia, was conducted, using a multistage random cluster sampling technique. The study included mosques that had an ablution area and regularly hosted five prayers a day. Sterile swabs were used for sampling, and the samples were transported to the laboratory for culture and analysis using a micro-scan system. A total of 199 (65%) samples contained several fungal species. Rhodotorula (74%), Cladosporium (47%), Bipolaris (46.6%), other yeasts (43.7%), Alternaria (40%), dematiaceous molds (34%), Curvularia (32.4%), and Candida (31%) were the most frequently isolated species. Species belonging to several other genera were also detected. This study revealed a relatively high prevalence of fungal organisms in mosque carpets in Riyadh, suggesting the need for implementing new strategies and laws to increase the level of hygiene awareness among worshipers and mosque caretakers to limit the spread of foot fungal infections.

Sex Correlation to the Prevalence of Pedal Neuromas in Various Interspaces: A Retrospective Study

BACKGROUND

Morton's neuromas are abnormalities of the common digital nerve branch located between the lesser metatarsal heads. Historically, interdigital (Morton's) neuromas have been characterized as being most common in the third interspace and in females. The principal investigator observed Morton's neuromas commonly in the second and third interspaces in both sexes. To our knowledge, no literature exists to evaluate Morton's neuroma location with a focus on each sex independently. The present study evaluates Morton's neuroma interspace location and whether there is a variation by sex.

METHODS

In this retrospective study, 582 deidentified magnetic resonance imaging reports with a diagnosis code for Morton's neuroma were evaluated for patients scanned from January 2, 2015, through April 19, 2016. Incomplete records and those with radiologist findings inconsistent with Morton's neuroma were eliminated. For the remaining 379 patients, data were collected on sex, laterality, history of trauma, plantar plate tear, age, and interspace location. Special focus was given to second and third interspace Morton's neuromas. Data were evaluated using the Pearson χ2 and independent-samples Mann-Whitney U tests, with P < .05 indicating statistical significance.

RESULTS

No statistically significant distribution between sex and second and third interspace Morton's neuromas was noted. Right vs left foot, age, and history of trauma did not vary statistically significantly between sexes. There was a statistically significant difference between the presence of plantar plate tears between sexes. Male patients with Morton's neuromas were found to have a higher rate of plantar plate tears (P = .01).

CONCLUSIONS

This study found that there were no statistically significant differences between sexes and Morton's neuromas location, laterality, or age.

Foot health among the Roma population of southern Spain according to the foot health status questionnaire

BACKGROUND

Foot health of the Roma population is a challenge for the health professionals where this minority is significant, as is the case in Spain. At present, little is known about foot health of the Roma population and their knowledge would promote the training of these professionals at the community level. Foot pain is common and a reason for consulting podiatry services. The purpose of this study was to determine foot health among the Roma population according to the Foot Health Status Questionnaire.

METHOD

An observational, cross-sectional and quantitative study conducted at the Roma population living in Spain in 2018. Self-reported data and the Foot Health Status Questionnaire were recorded. Examining the general health and foot health (foot pain, foot function, footwear and general health) and general (general health, social capacity, physical activity and vigour). This questionnaire is recommended as a valid and reliable patient-reported outcome. The obtained scores were compared.

RESULTS

A sample made up of 624 men and women from the Roma population took part in this study. 45% were Roma men and 55% Roma women. In the first section of the FHSQ, a lower score of values was recorded in the footwear domain (62.5) and in the general foot health domain (60). Gypsy women obtained lower scores in all the domains. In the second section, lower scores were obtained in the vigour (56) domain and in the general health (60) domain. A large effect size (r-Rosenthal) was found by gender in the footwear domain (0.334) and in the vigour domain (0.195). Roma women showed higher values in cardiac disorders, serious illnesses, doctor visits and foot problems. 67.8% reported that they had never been assisted by a podiatrist.

CONCLUSIONS

The studied Roma population has foot health problems, and these are more pronounced among women. They show lower values in the footwear and vigour domains. More professional training is required for health workers in this field to avoid cultural diversity stereotypes.

Risk factors for claw disorders in intensively finished Charolais beef cattle

This cross-sectional study aimed at performing a risk factor analysis of on-farm housing and management factors associated with infectious and non-infectious claw disorders of intensively finished Charolais young bulls and heifers. Claws' health condition of a total of 1305 animals belonging to 88 batches finished in farms located in the Eastern Po Valley (Italy) was assessed at slaughterhouse. Batch prevalence of feet affected by sole hemorrhage (SH) and white line abscess (WLA) was calculated and foot condition was summarized by infectious lesion (ILS) and non-infectious lesion (NILS) scores according to diseases' etiology. Batch prevalence of feet with SH, WLA, and assigned to the worst score classes were the outcomes in the risk factor analysis. Information about rearing facilities and health management of the tested batches were gathered in each origin farm along with a dietary sample used for chemical and physical analyses. Five categorized factors and 30 continuous covariates were considered as independent predictors and a cluster analysis of the continuous covariates was performed to select the most representative ones. Percentage of feet/batch affected by SH was on average 57.0 ± 32.5 % (SD) and by WLA was 9.94 ± 12.7 %. Percentage of feet/batch with the worst ILS and NILS was 29.6 ± 32.8 % and 12.5 ± 14.1 %, respectively. Charolais bulls showed a higher risk of SH and WLA than heifers and an increasing dietary NDF content acted as preventive factor. Concrete slats increased the risk of SH. Animals slaughtered in winter had the highest risk of WLA and the increasing level of dietary water-soluble carbohydrates (WSC) was a further risk factor. The risk for the worst NILS was lowest in spring and in presence of ventilation systems. It increased for bulls and in those batches fed diets with higher WSC content. Batches for which the farmer reported a higher prevalence of urgently slaughtered animals during finishing showed a higher risk of WLA and infectious claw diseases. The risk for infectious claw diseases was reduced in animals slaughtered in summer, housed on deep litter and fed diet with increased NDF content. It increased in farms where diet formulation was not under the nutritionist control. As general outcomes of the study, benefits for the claw health of finishing Charolaise may come from the use of the deep litter and ventilation systems, the involvement of a nutritionist in diet formulation, and the provision of diets with reduced WSC and increased NDF contents.

Case-control study of risk factors for pasture-and endocrinopathy-associated laminitis in North American horses

OBJECTIVE To investigate risk factors for the development of pasture- and endocrinopathy-associated laminitis (PEAL) in horses and ponies in North America. DESIGN Case-control study. ANIMALS 199 horses with incident cases of PEAL and 351 horses from 2 control populations (healthy horses [n = 198] and horses with lameness not caused by laminitis [153]) that were evaluated in North America between January 2012 and December 2015 by veterinarian members of the American Association of Equine Practitioners. PROCEDURES North American members of the American Association of Equine Practitioners were contacted to participate in the study, and participating veterinarians provided historical data on incident cases of PEAL, each matched with a healthy control and a lameness control. Conditional logistic regression analysis was used to compare data on PEAL-affected horses with data on horses from each set of controls. RESULTS Horses with an obese body condition (ie, body condition score ≥ 7), generalized or regional adiposity (alone or in combination), preexisting endocrinopathy, or recent (within 30 days) glucocorticoid administration had increased odds of developing PEAL, compared with horses that did not have these findings. CONCLUSIONS AND CLINICAL RELEVANCE The present study identified several risk factors for PEAL that may assist not only in managing and preventing this form of laminitis, but also in guiding future research into its pathogenesis.

Involvement of foot in patients with spondyloarthritis: Prevalence and clinical features

BACKGROUND

The purpose of this study was to evaluate the foot involvement in a group of patients with spondyloarthritis in regard to symptoms, type and frequency of deformities, location and radiological changes.

METHODS

We conducted a cross sectional study including 60 patients with spondyloarthritis over a period of six months. Anamnesis, clinical examination, podoscopic examination, biological tests and X-rays of feet were done for each patient.

RESULTS

Foot involvement was found in 31 patients (52%). It was symptomatic in 35% of cases and inaugural in 42% of cases. The most frequent site was the hindfoot (22 patients/31). Radiological findings were: erosion (17%), reconstruction (33%), erosion and reconstruction (50%). Forefoot involvement was found in 18/31 patients. Forefoot deformities were found in 9 patients. Two patients had sausage toe and feet skin abnormalities were observed in 12 patients. At podoscopic examination, 23 patients had abnormal footprints. Foot involvement was more frequent in peripheral spondyloarthritis (p=0.008). Patients with foot involvement had an advanced age of disease onset (p=0.05), a shorter disease duration (p=0.038) and more comorbidities (p=0.039). Foot involvement was correlated with C Reactive protein (p=0.043).

CONCLUSION

In our study, foot involvement and foot symptoms were seen frequently in spondyloarthritis and it is associated with late onset of the disease and with higher inflammation in blood tests.

Plantar Warts: Epidemiology, Pathophysiology, and Clinical Management

Verrucae plantaris (plantar warts) are common cutaneous lesions of the plantar aspect of the foot that are caused by the human papillomavirus (HPV). Ubiquitous in our environment, asymptomatic infection with HPV occurs frequently, with most infections controlled or cleared by cellular and humoral immune responses. However, certain populations have been observed to manifest plantar warts at higher rates compared with the general population, placing them at increased risk for wart-induced pain and complications. Plantar warts shed HPV, which can then infect other sites in the plantar region or spread to other people. Although controlling risk factors is useful in preventing infection, the pervasive nature of HPV makes these preventive measures frequently impractical. This literature review outlines the current knowledge regarding the relationship between plantar wart pathophysiology, HPV transmission, and epidemiologic characteristics. Given the high propensity for treatment resistance of plantar warts and no established, practical, and reliable method of prevention, HPV prophylaxis for populations that demonstrate high rates of plantar warts may be of benefit in controlling the spread of lesions.

Factors associated with prevalent and incident foot pain: data from the Tasmanian Older Adult Cohort Study

OBJECTIVES

To describe factors associated with prevalent and incident foot pain in a population-based cohort of older adults (n = 1092).

STUDY DESIGN

Longitudinal observational study.

MAIN OUTCOME MEASURES

Prevalent foot pain, incident foot pain after 5 years.

METHODS

Potential correlates included demographic factors, anthropometry, leg strength, metabolic factors, steps per day (using pedometer), pain at 6 other sites, and psychological wellbeing. Data were analysed using log binomial models.

RESULTS

Participants were aged 50-80 years (mean 63 years), 49% male, mean body mass index (BMI) 27.8 ± 4.7 at baseline. The prevalence of foot pain at baseline was 38% and the incidence of new pain over 5 years was 20%. BMI, pain at other sites (neck, hands, knees, pain at three or more sites), and poorer psychological wellbeing were independently associated with baseline foot pain. Baseline BMI and pain in the neck, hands, and knees were independently associated with incident foot pain; but change in weight or BMI, total number of painful joints and psychological wellbeing were not. Self-reported diabetes and cigarette smoking were not associated with prevalent or incident foot pain.

CONCLUSIONS

This study demonstrates that greater body weight and joint pain at multiple sites were consistently associated with prevalent foot pain and predict incident foot pain. Addressing excess body mass and taking a global approach to the treatment of pain may reduce the prevalence and incidence of foot pain in older adults.

Evaluation of podiatric disorders in a sample of children with intellectual disabilities: an analytical cross-sectional study

BACKGROUND

Intellectual disabilities (IDs) usually derive from neurodevelopmental disabilities. They limit intellectual functioning and cause adaptive behaviors and orthopedic problems. These disabilities have harmful effects on health, everyday practical skills and social functioning, and they diminish quality of life. The goal of our research was to perform podiatric evaluations on schoolchildren with and without ID and ascertain their records of foot disorders.

DESIGN AND SETTING

Analytical cross-sectional study conducted at a podiatric clinic in the city of Piedras Blancas, province of Asturias, Spain.

METHODS

An analytical cross-sectional study on 82 schoolchildren affected by ID, compared with 117 healthy schoolchildren, was conducted at a podiatric clinic. Demographic data, clinical characteristics and measurements relating to podiatric examinations were recorded among the participants who completed all phases of the tool that was used in the study process.

RESULTS

Almost 90% of the schoolchildren with and without ID presented foot disorders relating to smaller toes, nail disorders, flat feet or lower-limb alterations.

CONCLUSIONS

The participants showed elevated prevalence of foot disorders. Podiatric evaluations are a significant means for preventing the appearance of medical conditions and/or foot problems, and they also improve general health.

Incidence of lameness and association of cause and severity of lameness on the outcome for cattle on six commercial beef feedlots

OBJECTIVE To describe the incidence of specific causes of lameness and the associations of cause and severity of lameness on the outcome for cattle on commercial feedlots. DESIGN Dynamic population longitudinal study. ANIMALS Cattle on 6 commercial feedlots in Kansas and Nebraska during a 12-month period (mean daily population, 243,602 cattle; range, 223,544 to 252,825 cattle). PROCEDURES Feedlot personnel were trained to use a standardized diagnostic algorithm and locomotion score (LMS) system to identify and classify cattle by cause and severity of lameness. Information regarding lameness cause, severity, and treatments was recorded for individual cattle. Cattle were monitored until they left the feedlot (ie, outcome; shipped with pen mates [shipped], culled prematurely because of lameness [realized], or euthanized or died [died]). Incidence rates for various causes of lameness, LMSs, and outcomes were calculated. The respective associations of cause of lameness and LMS with outcome were evaluated. RESULTS Lameness was identified in 2,532 cattle, resulting in an overall lameness incidence rate of 1.04 cases/100 animal-years. Realized and mortality rates were 0.096 cattle/100 animal-years and 0.397 deaths/100 animal-years, respectively. Injury to the proximal portion of a limb was the most frequently identified cause of lameness followed by undefined lameness, septic joint or deep digital sepsis, and interdigital phlegmon (foot rot). As the LMS (lameness severity) at lameness detection increased, the percentage of cattle that died but not the percentage of cattle that were realized increased. CONCLUSIONS AND CLINICAL RELEVANCE Results provided clinically useful prognostic guidelines for management of lame feedlot cattle.

Soya bean meal increases litter moisture and foot pad dermatitis in maize and wheat based diets for turkeys but maize and non-soya diets lower body weight

1. A 2 × 2 factorial experiment was conducted to compare the effects of wheat or maize based diets differing in dietary electrolyte balance (DEB) on litter moisture and foot pad dermatitis (FPD) at 4, 8 and 12 weeks of age in heavy-medium turkeys. A second objective was to investigate the effects on foot pad dermatitis of the interaction between dietary composition and artificially increasing litter moisture by adding water to the litter. 2. High DEB diets contained soya as the main protein source whereas low DEB diets did not contain soya bean meal. Diets were formulated to be iso-caloric and iso-nitrogenous in each of 3 successive 4-week phases following recommended dietary compositions. DEB concentrations were 330, 290 and 250 mEq/kg in high DEB diets and 230, 200 and 180 mEq/kg in low DEB diets. 3. Litter moisture and mean FPD score were higher in turkeys fed on high DEB diets compared with low DEB diets whereas there was no difference between maize and wheat. 4. Food intake was similar and body weight was lower after litter moisture was artificially raised in the wet compared with the dry litter treatment and there was no interaction with dietary composition. 5. Mean body weight and feed intake were higher in turkeys fed on wheat compared with maize and in high DEB compared with low DEB diets at 12 weeks of age. 6. Lowering dietary DEB for turkeys may improve litter moisture and lower the prevalence of FPD in commercial turkey flocks.

Foot health and quality of life among university students: cross-sectional study

BACKGROUND

Foot problems are believed to reduce quality of life and are increasingly present. Even among young adults of university age, untreated foot problems can lead to postural and mobility problems. Accordingly, our aim here was to determine the relationship between foot health and quality of life and general health among male and female university students.

DESIGN AND SETTING

Observational cross-sectional quantitative study conducted at the Podiatric Medicine and Surgery Clinic of the University of Coruña, Ferrol, Spain.

METHODS

A sample of 112 participants of median age 22 years came to a health center, where self-reported data were registered, including professional activity, and scores obtained through the Foot Health Status Questionnaire (FHSQ) were compared.

RESULTS

In Section One of the FHSQ, the university students recorded lower scores of 66.66 in the footwear domain and 60 in the general foot health domain and higher scores of 84.37 in the foot pain domain and 93.75 in the foot function domain. In Section Two, they obtained lower scores of 60 in the overall health domain and 62.50 in the vigor domain and higher scores of 100 in the physical activity and 87.50 in the social capacity domain. Differences between males and females were evaluated using the Wilcoxon rank-sum test, which showing statistical significance (P < 0.05) regarding the dimensions of footwear and general foot health.

CONCLUSIONS

These university students' quality of life relating to foot health was poor. This appears to be associated with the university period, regardless of gender.

Foot Problems in Older Adults Associations with Incident Falls, Frailty Syndrome, and Sensor-Derived Gait, Balance, and Physical Activity Measures

BACKGROUND

Research on foot problems and frailty is sparse and could advance using wearable sensor-based measures of gait, balance, and physical activity (PA). This study examined the effect of foot problems on the likelihood of falls, frailty syndrome, motor performance, and PA in community-dwelling older adults.

METHODS

Arizona Frailty Cohort Study participants (community-dwelling adults aged ≥65 years without baseline cognitive deficit, severe movement disorders, or recent stroke) underwent Fried frailty and foot assessment. Gait, balance (bipedal eyes open and eyes closed), and spontaneous PA over 48 hours were measured using validated wearable sensor technologies.

RESULTS

Of 117 participants, 41 (35%) were nonfrail, 56 (48%) prefrail, and 20 (17%) frail. Prevalence of foot problems (pain, peripheral neuropathy, or deformity) increased significantly as frailty category worsened (any problem: 63% in nonfrail, 80% in prefrail [odds ratio (OR) = 2.0], and 95% in frail [OR = 8.3]; P = .03 for trend) due to associations between foot problems and both weakness and exhaustion. Foot problems were associated with fear of falling but not with fall history or incident falls over 6 months. Foot pain and peripheral neuropathy were associated with lower gait speed and stride length; increased double support time; increased mediolateral sway of center of mass during walking, age adjusted; decreased eyes open sway of center of mass and ankle during quiet standing, age adjusted; and lower percentage walking, percentage standing, and total steps per day.

CONCLUSIONS

Foot problems were associated with frailty level and decreased motor performance and PA. Wearable technology is a practical way to screen for deterioration in gait, balance, and PA that may be associated with foot problems. Routine assessment and management of foot problems could promote earlier intervention to retain motor performance and manage fear of falling in older adults, which may ultimately improve healthy aging and reduce risk of frailty.
