Prognostic factors and the value of radiographic osteoarthritis for persistent complaints after referral for ankle radiography.

Background: Ankle symptoms are a common reason to consult the general practitioner and often persist for years. In a population referred for ankle radiography, the prevalence of radiographic osteoarthritis (OA) is substantial, but its additional predictive value for persistent symptoms is unknown. Therefore, we examined the prognosis of symptoms 2-3 years after referral for ankle radiography, assessed clinical prognostic factors, and the additional predictive value of radiographic OA for persistent ankle complaints.

Is radiographic osteoarthritis associated with pain and disability of the ankle?

Objective: Ankle osteoarthritis (OA) is relatively understudied. It often affects younger people compared to OA in other joints. Evidence on the association between radiographic OA and ankle symptoms remains contradicting.

Prevalence of radiographic ankle osteoarthritis in different subgroups of patients referred for ankle radiography.

Background: Ankle osteoarthritis(OA) has detrimental effects on physical health and has a relatively early disease onset compared to OA in other joints. However, the prevalence of radiographic ankle OA in different subgroups of patients referred for ankle radiography remains unknown. Therefore, we aimed to determine the prevalence of radiographic talocrural, subtalar and talonavicular OA(Kellgren-Lawrence scale ≥2) in a population referred for ankle radiography.

Passive respiratory mechanics measured during natural sleep in healthy term neonates and infants up to 8 weeks of life.

The single occlusion technique (SOT) is a simple and noninvasive technique for measurement of passive respiratory mechanics in infants. Reference values based on measurements of a large population of healthy infants performed outside specialized research laboratories are lacking. The aim of this study was to present reference values for passive respiratory mechanics based on a large population of healthy term neonates and infants measured during natural sleep in routine care.
