ABSTRACT Context Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas have been detected with increasing frequency as a result of the progression of diagnostic modalities. Recently, invasive ductal carcinoma of the pancreas concomitant with IPMNs has been the focus of attention. Case report We report the case of a 57-year-old man with multifocal ductal carcinomas of the pancreas concomitant with IPMNs detected by intraoperative cytology. During a follow-up for branch duct IPMNs, a stenotic lesion of the main duct in the pancreatic body was found by ERCP, and brush cytology of the stenosis revealed an adenocarcinoma. A distal pancreatectomy was proposed; however, intraoperative pancreatic juice cytology from the pancreatic head also revealed adenocarcinoma, and a total pancreatectomy was finally carried out. Pathological examination of the resected specimen showed multifocal ductal carcinomas and IPMNs in the distal pancreas, and invasive ductal carcinoma in the pancreatic head which had not been detected by preoperative imaging studies. Conclusions Surgeons should be aware of the possibility of multifocal carcinomas in patients with concomitant IPMNs. Intraoperative pancreatic juice cytology should always be performed in order to confirm the absence of carcinoma in the pancreas to be left in place after planned resection

Influence of primary and secondary prevention indications on anxiety about the implantable cardioverter-defibrillator

AbstractBackgroundImplantable cardioverter-defibrillators (ICDs) have been established for primary and secondary prevention of fatal arrhythmias. However, little is known about the influence of ICD indications on quality of life (QOL) and psychological disturbances. This study aimed to examine whether there were differences in QOL and psychological distress in patients that have an ICD for primary or secondary prevention of fatal arrhythmias.MethodsA multicenter survey of 179 consecutive outpatients (29.1% primary prevention) with ICD implantations completed the Short Form-8 (SF-8), Beck Depression Inventory (BDI), Impact of Event Scale-Revised (IES-R), State-Trait Anxiety Inventory (STAI), and Worries about ICD (WAICD).ResultsPatients with an ICD for primary prevention had a higher trait anxiety score and worries about ICD score than patients with an ICD for secondary prevention (41.7±12.4 vs. 34.7±12.3, p=0.001 and 39.6±18.0 vs. 30.0±18.9, p=0.002, respectively), even after adjusting for demographic and clinical characteristics. In multivariable analysis of variance, primary prevention ICD recipients reported a poorer QOL on the vitality subscale of the SF-8.ConclusionsIn our study population, which mostly consisted of New York Heart Association (NYHA) class I and II subjects, primary prevention ICD recipients were more prone to experience worries about their ICD, anxiety, and a poorer QOL compared to secondary prevention ICD recipients. In clinical practice, primary prevention ICD patients should be closely monitored. If warranted, they should be offered psychological intervention, as anxiety and low QOL were predictors of mortality

The effect of a prostaglandin E-1 derivative on the symptoms and quality of life of patients with lumbar spinal stenosis

Quality of life (QOL) is a concern for patients with lumbar spinal stenosis (LSS). In this study, QOL was examined using the 5-item EuroQol (EQ-5D). QOL and activities of daily living (ADL) were surveyed for 91 patients who visited 18 medical institutions in our prefecture and were diagnosed with LSS-associated intermittent claudication. A second survey was performed after a parts per thousand yen6 weeks for 79 of the subjects to evaluate therapy with limaprost (an oral prostaglandin E1 derivative) or etodolac (an NSAID). Symptoms, maximum walking time, QOL, ADL items, and relationships among these variables were investigated for all 91 patients. Leg pain, leg numbness, and low back pain while walking were surveyed by use of VAS scores (0-100). Leg pain, leg numbness, and low back pain while walking (VAS a parts per thousand yen25) were present in 83.5, 62.6, and 54.9 % of the patients in the first survey, and approximately half of the patients had a maximum walking time 30 min, showing that maximum walking time affected health-related QOL. Of the 79 patients who completed the second survey, 56 had taken limaprost and 23 (control group) had received etodolac. Limaprost improved possible walking time, reduced ADL interference, and significantly increased the EQ-5D utility score, whereas no significant changes occurred in the control group. Maximum walking time was prolonged by a parts per thousand yen10 min and the EQ-5D utility value was improved by a parts per thousand yen0.1 points in significantly more patients in the limaprost group than in the control group. According to the findings of this survey, at an average of 8 weeks after administration limaprost improved symptoms, QOL, and ADL in LSS patients whereas treatment with an NSAID reduced pain but did not have any other effects.ArticleJOURNAL OF ORTHOPAEDIC SCIENCE. 18(2):208-215 (2013)journal articl

Spectrofluorophotometric quantum counter dye for fluorescent samples under excitation of light 600-700 nm wavelength range was investigated. Five kinds of cyanine, three of methylene blue and three of phthalocyanine dyes respectively, were provided for examination. As the results of characteristic measurements, we found that methylene blue trihydrate has most superior characteristics for absorption-fluorescent spectra and for stabirity. Measuring the fluorescent spectra of fluorescent samples (cyanine dye) under various exciting light intensities, using the methylene blue trihydrate for spectrofluorophotometric quantum counter dye, the practical accuracy of this quantum counter dye was proofed. Adjustment of the compensator of spectrofluorophotometer enabled us to measure corrected fluorescent spectrum until wavelength by 830 nm. Consequently, relative fluorescent quantum yields for samples such as cyanine dyes has become obtainable till nearinfrared wavelength range

Wide wavelength range spectrofluorophotometer, exchangeable for short (300～600 nm) and for long (485～825 nm) wavelength compensating channels, has been designed on the base of Shimazu RF-502 spectrofluorophotometer, using Rhodamine B and Methylene blue as quantum counter dyes. Making of compensator suitable for this system. and spectral energy correction on fluorescent spectrometer and on photomultipliyer by standard tungsten lamp have been examined. Moreover to connect personal computer with this wide wavelength range spectrofluorophotometer an input preamplifier and programs for data treatment were designed, and consequently real time operation become enabled. 0n the results of above experiments the wide wavelength spectrofluorophotometric measurements with highly accuracy has becom expected, comparing fluorescent samples having long wavelength spectrum such as cyanine dyes with that of short wave characteristics having well known fluorescent quantum yield
