The therapeutic effect of a cordless mini TENS on shoulder stiffness and painful diseases and patients' favorite intensity of stimulation were studied. Effect of this apparatus on peripheral circulation was also examind using a laser Doppler measuring instrument. The 114 cases with shoulder stiffness used the TENS only once (SS group), and the 53 cases continuasly (SC group). The 65 cases with painful diseases used the TENS only once (PS group) and the 53 cases continuasly (PC group). A great majority of the patients prefered stimulation with moderate frequency and high intensity. Effectiveness was seen in 76% of SS group and 87% of SC group, and in 75% of PS group and 91% of PC group. Peripheral circulation was significantly increased after the stimulation of the apparatus.

BACKGROUND/AIMS: In this study, we aimed to evaluate the predictive value of localized stenosis of the main pancreatic duct (MPD) for early detection of pancreatic cancer.METHODS: Among 689 patients who underwent endoscopic retrograde pancreatography from January 2008 to September 2018, 19 patients with MPD findings were enrolled. These patients showed findings for indicating suspicious pancreatic cancer at an early stage (FiCE); FiCE was defined as a single, localized stenosis in the MPD without a detectable mass (using any other imaging methods) and without other pancreatic diseases, such as definite chronic pancreatitis, intraductal papillary mucinous neoplasm, and autoimmune pancreatitis. Final diagnoses were established by examining resected specimens or through follow-up examinations after an interval of >5 years.RESULTS: Among 19 patients with FiCE, 11 underwent surgical resection and 8 were evaluated after a >5-year observation period. The final diagnosis of the MPD stenosis was judged to be pancreatic cancer in 9 patients (47%), including 3 with intraepithelial cancer, and to be a non-neoplastic change in 10. The sensitivity, specificity, and accuracy of preoperative pancreatic juice cytology were 75%, 100%, and 88%, respectively.CONCLUSIONS: The predictive value of FiCE for pancreatic cancer prevalence was 47%. Histological confirmation with pancreatic juice cytology is necessary before surgical resection.
