Résumé
Methods@#In this study, we prospectively examined 70 LSS patients with intermittent claudication symptoms at a multicenter outpatient clinic. A walking test was administered at baseline and week 4 to assess patients’ walking distance and lower limb pain and numbness. Immediately after the walking test, patients were asked to use the Visual Analog Scale (VAS) to rate their pain and numbness in the front, back, outside, inside, and hip of the lower legs. The reproducibility of the walking test was evaluated using Cohen’s κ analysis and intraclass correlation coefficients (ICCs). Meanwhile, the Swiss Spinal Stenosis (SSS) Questionnaire was used to evaluate the severity of the stenosis. @*Results@#The walking distance ICC at baseline and at week 4 remained unchanged at 0.7, with acceptable interobserver reliabilities for lower limb pain and numbness in both legs. The average VAS score for lower leg pain was 23.2±25.2 mm at baseline and 27.4±28.8 mm at week 4, while the corresponding average VAS score for numbness was 23.4±26.7 mm at baseline and 24.8±25.2 mm at week 4. The ICC score was 0.7 for leg pain and 0.7 for numbness. The mean SSS was 30.2±5.5 at baseline and 29.2±5.2 at week 4, and there was no significant difference in the severity. @*Conclusions@#The walking test for LSS has acceptable reproducibility.
Résumé
Background/Objective: Extramammary Paget’s Disease (EMPD) seems to be more common in Caucasians than Chinese. We report the clinical manifestations, management, and prognostic characteristics in 17 Chinese patients. Methods: Medical records and biopsies of 17 patients who had been treated at a large university hospital in China between March 2005 and January 2012 were reviewed. Results: Of the 17 patients, 14 were men. They had lesions on the scrotum and the penis. Of the three women, two had vulvar and one had inguinal lesions. All patients underwent Mohs micrographic surgery (MMS). Three men had metastasis to the inguinal lymph nodes and underwent an extensive local excision with inguinal lymphadenectomy. Eight patients who had positive excision margins received additional radiation therapy. The mean follow-up duration was 54 months (4-85 months). One patient had two recurrences. Three had metastasis to the inguinal lymph node. One had metastasis to the bone and concomitant prostate cancer. Two patients died of the disease. Conclusion: A striking difference in presentation of EMPD in Chinese compared with Caucasians is the male predominance and location on the penis and scrotum. Mohs micrographic surgery followed by radiotherapy is an effective treatment. Long-term follow-up suggests that the disease has a good prognosis when it does not metastasise.
