Low Serum Vitamin D Levels May Contribute to Gastric Dysmotility in de novo Parkinson's Disease.

Background And Objectives: Gastrointestinal dysfunction is a common non motor symptom in Parkinson's disease (PD). However, the potential association between vitamin D and gastroparesis in PD has not been previously investigated. The aim of this study was to compare vitamin D levels between drug-naive de novo PD patients with normal gastric emptying and those with delayed gastric emptying.

Role of PET or PET/CT in the post-therapy surveillance of uterine sarcoma.

Objective: To evaluate the clinical accuracy and clinical impact of positron emission tomography (PET) or positron emission tomography/computed tomography (PET/CT) in detecting and treating tumor recurrence in patients with treated uterine sarcoma.

Methods: Results of 36 patients who underwent PET or PET/CT in post-therapy surveillance of uterine sarcoma were retrospectively assessed. Histopathologic confirmation or clinical/radiological outcome at least 6 months after PET or PET/CT was standard of reference.

Comparison of the validity of magnetic resonance imaging and positron emission tomography/computed tomography in the preoperative evaluation of patients with uterine corpus cancer.

Objective: To compare positron emission tomography/computed tomography (PET/CT) with magnetic resonance imaging (MRI) in the preoperative detection of primary lesions and lymph node (LN) and distant metastases in patients with uterine corpus cancer.

Methods: The patient cohort consisted of 53 women with uterine corpus cancer who underwent preoperative workup, including both MRI and PET/CT scans, and underwent surgical staging, including pelvic and/or paraaortic LN dissection, between October 2004 and June 2007 at Asan Medical Center, Seoul, Korea. Pathologic data from surgical staging were compared with the preoperative MRI and PET/CT results.
