ABSTRACT
INTRODUCTION: Non-motor fluctuations (NMF) in Parkinson's disease (PD) remain poorly recognized but have a high impact on patients' quality of life. The lack of assessment tools limits our understanding of NMF, compromising appropriate management. Our objective was to validate a hetero-questionnaire for NMF in PD patients at different stages of the disease: without treatment, without motor fluctuations, with motor fluctuations. METHODS: We included patients in 15 centers in France. Our questionnaire, NMF-Park, resulted from previous studies, allowing us to identify the more pertinent NMF for evaluation. Patients reported the presence (yes or no) of 22 selected NMF, and their link with dopaminergic medications. The assessment was repeated at one and two years to study the progression of NMF. We performed a metrological validation of our questionnaire. RESULTS: We included 255 patients (42 without treatment, 88 without motor fluctuations and 125 with motor fluctuations). After metrological validation, three dimensions of NMF were found: dysautonomic; cognitive; psychiatric. The sensory/pain dimension described in the literature was not statistically confirmed by our study. DISCUSSION: Our questionnaire was validated according to clinimetric standards, for different stages of PD. It was clinically coherent with three homogeneous dimensions. It highlighted a link between fatigue, visual accommodation disorder, and cognitive fluctuations; and the integration of sensory/pain fluctuations as part of dysautonomic fluctuations. It focused exclusively on NMF, which is interesting considering the described differences between non-motor and motor fluctuations. CONCLUSION: Our study validated a hetero-questionnaire of diagnosis for NMF for different stages of PD.

A prosthesis was designed to protect the intestinal loop from external beam radiation therapy when post-operative radiation is indicated. It is a silicone inflatable balloon, which, when implanted displaces the intestinal loops out of the pelvic irradiation field. The prosthesis can be deflated between each course of irradiation, without surgery. The device has been used in 8 patients: 6 patients with recurrent pelvic tumor (2 rectal cancers, 1 anal cancer, 1 cancer of the endometrium, 1 cervical carcinoma, 1 ovarian carcinoma), 2 patients with primary tumor (1 malignant paraganglioma, 1 cervical carcinoma). Radiotherapy was administered by means of high power appliances. After radiotherapy, the prosthesis was deflated, then removed through a 3 cm incision under local or peridural anesthesia. The tolerance of the small intestine to the radiation therapy has been satisfactory in each case with no bowel injury due to radiation. Therefore, this simple device might be useful to prevent bowel injury during postoperative radiation in the treatment of abdominal and retroperitoneal tumor masses.
