We present a case study of a 5-year-old patient, who presented with left-sided torticollis. Due to persistence of problems, a CT and an MRI were made showing a single osteolytic lesion centred on right occipital condyle. After an open biopsy, histology confirmed it to be Langerhans cell histiocytosis (LCH). Torticollis or restricted range of motion is a presenting feature in 76% of children with LCH with cervical involvement. There remains much debate on the best treatment strategy. The clinical and radiological outcomes of the case study presented on this article support the treatment of LCH with chemotherapy in cases with solitary involvement of the occipital condyle.
Patient satisfaction has gained relevance in clinical practice, and knowing the variables with the greatest predictive power in this assessment is vital. The primary objective of this study was to evaluate the relationship between postoperative satisfaction of patients undergoing total knee arthroplasty (TKA) and acquired functioning and to determine differences between sexes. This retrospective observational study included 183 patients undergoing TKA between 2018–2021. Functioning variables were pain, range of motion, gait distance, and WOMAC domains. There were significant differences in gait distance, pain, and WOMAC between the pre- and postoperative periods. Women had worse scores in final evaluation moments, although satisfaction was similar between the sexes. Satisfaction and the difference and the rate of change in WOMAC were significantly correlated. In the classification and regression tree analysis, the variable that most differentiated satisfaction in women was the WOMAC variation; in men, it was the pain variation rate.
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.
