Background
The measures used for the diagnosis of biomechanical pathologic disorders are variable. The aim of this study was to determine the concordance between the Clarke angle and the Chippaux-Smirak and Staheli indices in evaluation of the footprints of kidney transplant patients.
Methods
An observational prevalence study was performed in kidney transplant patients in the University Hospital Complex A Coruña from 1981 through 2014. After obtaining patient informed consent and ethics committee approval, sociodemographic (age and sex) and anthropometric (body mass index) variables and comorbidity (Charlson Comorbidity Index score) were assessed for each patient, and a podiatric medical examination was performed of the footprint through a pedigree (Chippaux-Smirak index, Staheli index, and Clarke angle). A descriptive analysis of all of the variables was performed; for agreement, the kappa index and the Bland-Altman method were used.
Results
We found a predominance of male sex (65.6%) and a high level of overweight (43.3%) in the sample. The highest concordance between the indices studied is presented by the Chippaux-Smirak index, with a kappa index of 0.86 for the left foot and 0.76 for the right foot.
Conclusions
High agreement was attained among observers in measurements of the footprints of kidney transplant patients.
Background
Podiatric medical abnormalities are highly prevalent, yet few random population studies exist that determine the presence of pathologic abnormalities in the feet, despite their importance. The aim of this study was to determine the prevalence of podiatric medical abnormalities in a random sample population 40 years or older.
Methods
An observational study was conducted of a random sample population (n = 1,002) located in A Coruña, Spain. Anthropometric variables, comorbidity (Charlson score), quality of life (36-item Short-Form Health Survey), and podiatric medical examination findings were studied. A descriptive analysis and multivariate logistic regression were performed.
Results
The most common diseases were claw toes (69.7%), hallux valgus (38%), and hallux extensus (15.8%), which increased with age and female sex. The most frequent metatarsal formula was index minus (40.9%), followed by index plus minus (35.0%). The most frequent digital formula was Egyptian foot (57.1%), followed by Greek foot (31.4%). In this study, although the presence of podiatric medical abnormalities reduced the probability of enjoying a better quality of life, it did not do so significantly. After taking into account age, sex, comorbidity, body mass index (BMI), and the presence of podiatric medical abnormalities, the variables with an independent effect that modified the physical component of quality of life were sex (female), comorbidity, and BMI.
Conclusions
There was a high prevalence of podiatric medical abnormalities, which increased with age and female sex. Comorbidity, BMI, and sex modified quality of life independently of podiatric medical abnormalities.
