Adult-onset Still's disease is an uncommon rheumatological syndrome with a diversity of signs and symptoms. Pulmonary manifestations described are pleuritis and usually transient radiologic infiltrations. The patient presented in this case report had biopsy-proven lung fibrosis when adult-onset Still's disease was diagnosed. Three years after diagnosis, the patient developed clinical signs of the interstitial lung disorder. Radiological and histological progression was observed. Other causes of interstitial lung disorders were excluded. Clinicians should be aware that interstitial lung disease can be a complication of adult-onset Still's disease and can compromise the clinical status of the patient.
Nutritional assessment of elderly people is limited due to a lack of age-corrected standards. The objective of this study was to develop a new, more age-independent index for nutritional assessment by correcting the creatinine height index (CHI) for the age-induced changes in its variables. This might improve the differentiation between physiological reduction in muscle mass in elderly people and the changes induced by malnutrition. Seventy-four elderly and 100 young healthy volunteers were compared by anthropometric and biochemical-assessment variables. From the high correlation between total arm length and body length (r = 0.86; P less than 0.001) and the use of an alternative formula to calculate ideal body weight (IBW) from height and wrist circumference, a relatively age-independent estimate of IBW was determined. Creatinine arm index, as an adapted index of CHI, is proposed based on this age-independent IBW estimation and a specific creatinine coefficient for different age groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
