Comparison of a video versus paper questionnaire on functional limitation in lower limb osteoarthritis.

INTRODUCTION: The video Animated Activity Questionnaire (AAQ) was developed to assess the impact of lower limb osteoarthritis (OA) on daily functional activities. The objective of the study was to compare the video and the HOOS/KOOS paper questionnaires and to assess the effect of order of administration. MATERIAL AND METHODS: Patients recruited in the KHOALA cohort were randomized in two groups: AAQ questionnaire first (AAQ-first group) and HOOS (hip)/KOOS (knee) questionnaire first (H/KOOS-first group). Within group differences between AAQ and HOOS/KOOS scores were compared using a Student t-test. The Spearman correlation coefficient between AAQ score and HOOS/KOOS score was calculated in each group then compared, using Fisher z-transformation. RESULTS: Among 200 randomized patients, 188 (65.8 years, 66.0% women) completed the questionnaires: 99 in the AAQ-first group and 89 in the H/KOOS-first group. The AAQ score was 85.9 (SD: 13.7) in the AAQ-first versus 87.8 (SD: 13.1) in the H/KOOS-first group (p = 0.34). The H/KOOS score was 72.5 (SD: 21.2) in the AAQ-first versus 73.5 (SD: 18.4) in the H/KOOS-first group (p = 0.71). The Spearman correlation coefficient between AAQ and H/KOOS in the AAQ-first was 0.84[0.77-0.89] and 0.73[0.61-0.81] in H/KOOS-first group. These correlations differed between groups significantly (p = 0.02). CONCLUSION: This study found video AAQ and paper HOOS/KOOS questionnaire highly correlated, with a moderate but significant effect of order administration of video and paper questionnaires evidencing a stronger correlation when the videos were viewed first.

[Cutaneous metastases on the extremities]. / Métastases cutanées des extrémités.

BACKGROUND: Cutaneous metastases (CM) on the extremities are rare complication of cancer with poor prognosis. In general, lesions simulate an infection. Herein, we report two new cases with atypical presentation. PATIENTS AND METHODS: Case no 1: a 71-year-old man consulted for suspicion of left hand pyogenic granuloma present for 3 months. His history revealed two treated squamous-cell carcinomas (tongue and lung). On physical examination, he presented three budding and foul-smelling lesions on his left hand. Histopathology showed metastasis of squamous-cell carcinoma. Radiographic examination revealed spread of pulmonary nodules with suspicion of metastasis. Case no 2: a 68-year-old man was hospitalized for indurated edema of the right leg present for several months. Six months earlier, he had undergone surgery for left pulmonary adenocarcinoma without metastasis. Physical examination revealed an indurated edema on the right foot. Histopathology showed metastasis from adenocarcinoma. A scan revealed several osteolytic lesions in the right foot as well as lymphadenopathy. DISCUSSION: Herein, we report two original cases of CM of the extremities diagnosed as tumor progression. This is a rare complication of variable clinical presentation and impacts both cancer management and prognosis. It is important to consider the diagnosis when distal cutaneous lesions persist, particularly where there is a history of cancer.
