This article reports 2 cases of urinary retention in Alzheimer's disease with agitation treated by acupuncture. Based on patients' clinical symptoms, the etiology and pathogenesis were determined, and acupuncture was applied to Baihui (GV20), Sishencong (EX-HN1), Shenting (GV24), and bilateral Ciliao (BL32), Zhongliao (BL33), Fengchi (GB20), Taiyang (EX-HN5), etc. to regulate the mind and promote water metabolism. The positive and negative electrodes of the SDZ-Ⅴ type electroacupuncture device were attached to ipsilateral Ciliao (BL32), Zhongliao (BL33) respectively, with continuous wave, at the frequency of 15 Hz, and the current of 3 to 10 mA, depending on patients' tolerance. The needles were retained for 20 min. The treatment was delivered once every other day, 3 interventions a week and 12 interventions as 1 course. Both patients reported the micturition desire after 1 intervention with acupuncture and the catheter was removed on the same day. The urination was ameliorated without dysuresia after 1-2 courses of treatment, and the agitated behavior was alleviated. It can be the reference for the clinical treatment of urinary retention in patients with Alzheimer's disease with agitation.

Prostate cancer (CaP) is the most common cancer diagnosed among men in the United States and the fifth most common cancer among men in Korea. Unfortunately, the early stages of CaP may have no symptoms. Thus, early detection is very important and physicians managing voiding dysfunction must have awareness about CaP. The traditional tests used for early detection of CaP are the prostate-specific antigen (PSA) blood test and digital rectal examination. However, a high PSA level is not specific for CaP. Benign prostatic hyperplasia, prostatitis, urinary tract infection, and urinary retention can all cause a high PSA level. Thus, no test shows sufficient accuracy to truly be useful for screening men for CaP. A prostate biopsy is the only method that yields a definitive diagnosis of CaP; however, this test is invasive and uncomfortable. Recently, new biomarkers for CaP detection have been proposed to improve the accuracy of the PSA test. In this review, we summarize our knowledge of various new biomarkers, including PSA-associated biomarkers (the prostate health index and 4Kscore), molecular biomarkers (PCA3, TMPRSS2: ERG fusion gene, and various miRNAs), and proteomics-associated biomarkers, and the ways in which they may improve the detection rate of CaP. Accordingly, this review can raise awareness about CaP to physicians managing voiding dysfunction and be a good reference for them.

OBJECTIVETo investigate the clinical efficacy and safety of modified stapled transanal rectal resection (STARR) combined with perioperative pelvic floor biofeedback therapy (POPFBFT) in treating obstructed defecation syndrome (ODS).

METHODSThirty female ODS patients underwent modified STARR (resection and suture was performed in rectocele with one staple) combined with POPFBFT in Department of Colorectal and Anal Surgery, The First Hospital of Jilin university from October 2013 to March 2015. Before the modified STARR, patients received a course of POPFBFT (20 min/time, 2 times/d, 10 times as a course), and another 2 courses were carried out in clinic after discharge. Efficacy evaluation included general conditions of patients, morbidity of postoperative complication, overall subjective satisfaction (excellent: without any symptoms; good: 1 to 2 times of laxatives per month and without the need of any other auxiliary defecation; fairly good: more than 3 times of laxatives per month ; poor: with no improvement; excellent, good, fairly good are defined as effective), Longo ODS score (range 0 to 40 points, the higher the score, the more severe the symptoms), gastrointestinal quality of life index(GIQLI)(range 0 to 144 points, the lower the score, the more severe the symptoms), anorectal manometry and defecography examination. The follow-up lasted 12 months after operation (ended at April 2016).

RESULTSAverage age of 30 patients was 57(46 to 72) years and Longo ODS score of every patient was ≥9 before operation. The modified STARR was completed successfully in all the 30 patients with average operation time of 25 (18 to 34) min and average hospital stay of 6(4 to 9) d. Postoperative complications included pain(20%, 6/30), urinary retention (16.7%, 5/30), anorectal heaviness (6.7%, 2/30), and fecal urgency(26.7%, 8/30). Anaorectal heaviness and fecal urgency disappeared within 3 months. No severe complications, such as postoperative bleeding, infection, rectovaginal fistula, anastomotic dehiscence and anal incontinence were observed. The effective rate of overall subjective satisfaction was 93.3%(28/30) during the follow-up of 12 months. There was no significant difference in Longo ODS score between pre- POPFBFT and pre-operation (pre- POPFBFT: 32.95±3.22, pre-operation: 32.85±3.62, t=1.472, P=0.163). Compared with pre-POPFBFT, Longo ODS score at 1 week after operation decreased (t=4.306, P=0.000), moreover, score at 1 month after operation was lower than that at 1 week (13.05±7.49 vs. 15.00±7.17, t=7.322, P=0.000), while no significant differences were found among 1, 3, 6, 12 months after operation (F=2.111, P=0.107). Likewise, there was no significant difference in GIQLI score between pre-POPFBFT and pre-operation (pre-POPFBFT: 79.39±17.14, pre-operation: 76.65±17.56, t=1.735, P=0.096). Compared with the pre-POPFBFT, GIQLI score at 1 week after operation increased (t=4.714, P=0.000), moreover, GIQLI score at 1 month after operation was higher than that at 1 week (102.26±19.24 vs 91.31±21.35, t=5.628, P=0.000), while no significant differences were found among 1, 3, 6, 12 months after operation(F=1.211, P=0.313). In comparison with pre- POPFBFT, parameters of defecography examination at 12 months after operation showed obvious improvement: the rectocele decreased from (34.1±0.4) mm to (3.1±0.3) mm (t=6.847, P=0.000), anorectal angle during defecation increased from (123.8±6.7)degree to (134.7±8.5)degree, enlargement of anorectal angle during defecation increased from (29.1±3.5)degree to (37.1±5.3)degree, while no significant differences in descend of perineum, anorectal angles at rest as well as parameters of anorectal manometry were found (all P>0.05).

CONCLUSIONModified STARR combined with POPFBFT is safe and effective for ODS patients.

PURPOSE: Cardiopulmonary resuscitation (CPR) training can improve performance during simulated cardiac arrest; however, retention of skills after training remains uncertain. Recently, hands-only CPR has been shown to be as effective as conventional CPR. The purpose of this study was to compare the retention rate of CPR skills in laypersons between the two hands-only and conventional CPR training methods. METHODS: Participants were randomly assigned to one of the two training groups: The hands-only CPR group with 80 minutes of training or the conventional CPR group with 180 minutes of training. The CPR skills for each participant were evaluated at the end of the training session and at 3 months thereafter, using the Resusci Anne® manikin with a skillreporting software. RESULTS: A total of 252 participants completed the training sessions; of which, 125 participants were in the hands-only CPR group and 127 in the conventional CPR group. After 3 months, 118 participants were randomly selected to complete a post-training test. The hands-only CPR group showed a significant decrease in the average compression rate (p=0.015), average compression depth (p=0.031), and proportion of adequate compression depth (p=0.011). Contrastingly, there were no differences with respect to the retention of skills in the conventional CPR group after 3 months. CONCLUSION: The conventional CPR training appears to be more effective with respect to retention of chest compression skills compared with hands-only CPR training; however, the retention of artificial ventilation skills after conventional CPR training remains poor.

PURPOSE: Urinary catheterization is a common technique in clinical practice. There is, however, no consensus on management prior to removal of the indwelling catheter for short-term patients. This systematic review examined the necessity of clamping before removal of an indwelling urinary catheter in short-term patients. METHODS: A systematic literature review was conducted using eight databases and predetermined keywords-guided searches. Some 2,515 studies were evaluated. Ten studies that met the inclusion criteria were selected. RESULTS: The quality of the studies was assessed using the Jadad scoring system. Only 40.0% of studies were rated as high quality. This review found that catheter clamping prior to removal was not necessary for the short-term patient. When made a comparison with the unclamping group, there was no significant difference in recatheterization risk, risk of urine retention, patients' subjective perceptions and rate of urinary tract infection. CONCLUSIONS: This review indicated that bladder training by clamping prior to removal of urinary catheters is not necessary in short-term catheter patients. In addition, clamping carries the risk of complications such as prolonging urinary catheter retention and urinary tract injury. Further investigation requires higher quality methodologies and more diverse study designs.

PURPOSE: To assess the retention of glass fiber post cemented with self-adhesive resin cement into optimum and over-prepared root canals following obturation in the presence of either eugenol (EB) or calcium hydroxide (CB)-based sealers. MATERIALS AND METHODS: Roots of extracted premolars were endodontically-treated in 5 groups (n = 10). Roots of Group 1 (control) were left with no obturation and then optimally prepared to receive endodontic dowels. Other root canals were obturated with gutta-percha in the presence of either eugenol-based (Groups 2 and 4) or calcium hydroxide-based (Groups 3 and 5) sealer. Dowel spaces were prepared with optimal diameter in Groups 2 and 3, one size larger in Groups 4 and 5. Standardized fiber posts were luted to the prepared spaces using self-adhesive resin cement and itsretention was then tested on an universal testing machine. Both one-way ANOVA and Tukey's HSD comparisons (alpha=0.05) were used to identifythe significance of inter-group retention differences. Scanning electron microscopy (SEM) of both optimally and over-prepared dowel spaces was also considered to figure the nature of their interior out. RESULTS: The post retention was significantly higher to the non-obturated, optimally-prepared dowel spaces of Group 1 compared to the obturated, optimally-prepared ones of Groups 2 and 3. For each dowel space diameter, root canals obturated using CB of Groups 3 and 5 showed significantly higher dowel retention compared to those obturated using EB of Groups 2 and 4. Post retention to the over-prepared dowel spaces of Groups 4 and 5 was significantly higher than that recorded for the optimally-prepared ones of Groups 1-3. SEM images revealed traces of endodontic sealer and gutta-percha on the walls of the optimally-prepared dowel spaces. CONCLUSION: Despite the adverse effect of endodontic sealers on the retention of fiber posts, the over-preparation of dowel spaces helps to improve the retention.

PURPOSE: The purpose of this study was to investigate the effect of resin cements and primer on the retentive force of zirconia copings bonded to zirconia abutments with insufficient retention. MATERIALS AND METHODS: Zirconia blocks (Lava, 3M ESPE, St. Paul, MN, USA) were obtained and forty sets of zirconia abutments and copings were fabricated using CAD/CAM technology. They were grouped into 4 categories as follows, depending on the types of resin cements used, and whether the primer is applied or not:Panavia F2.0 (P), Panavia F2.0 using Primer (PRIME Plus, Bisco Inc, Schaumburg, IL, USA) (PZ), Superbond C&B (S), and Superbond C&B using Primer (SZ). For each of the groups, the cementation was conducted. The specimens were kept in sterilized water (37degrees C) for 24 hours. Retentive forces were tested and measured, and a statistical analysis was carried out. The nature of failure was recorded. RESULTS: The means and standard deviations of retentive force in Newton for each group were 265.15 +/- 35.04 N (P), 318.21 +/- 22.24 N (PZ), 445.13 +/- 78.54 N (S) and 508.21 +/- 79.48 N (SZ). Superbond C&B groups (S & SZ) showed significantly higher retentive force than Panavia F2.0 groups (P & PZ). In Panavia F2.0 groups, the use of primer was found to contribute to the increase of retentive force. On the other hand, in Superbond C&B groups, the use of primer did not influence the retention forces. Adhesive failure was observed in all groups. CONCLUSION: This study suggests that cementation of the zirconia abutments and zirconia copings with Superbond C&B have a higher retentive force than Panavia F2.0. When using Panavia F2.0, the use of primer increases the retentive force.

The purpose of this review is to examine the performance of attachments used in implant-supported overdenture (IOD) in both clinical and in vitro settings and report the compiled findings, comparisons, and trends in the research literature. Articles published in PubMed on IOD attachment systems and performance were reviewed. Non-original articles were excluded. For each article included, the type of study, number of implants, number of attachment systems, and study outcome were recorded. Of the 283 articles found, 158 met the inclusion criteria. Ninety-four articles were clinical studies and 64 articles were in vitro studies. Studies on retention were the most common for in vitro studies, and four or more attachment systems were compared in most articles with significant differences in outcome. A clinical outcome of one attachment system was most common for clinical studies, while most studies had neutral outcomes overall. Ball attachment was the most commonly tested IOD attachment system. The trend in the literature showed that there is a large discrepancy between the study designs and outcomes between the clinical and the in vitro studies for IOD. Further clinical studies that can validate in vitro research should be encouraged to address this discrepancy between the two areas.

BACKGROUND/AIMS: Lack of simple and repeatable tests hampers gastric emptying studies in rats. The aim of this study was to adapt the 14C-octanoate solid gastric emptying breath test for application in rats, and to validate it against radioscintigraphic method. METHODS: After ingestion of a meal containing 3 mCi 99mTc and 2 microCi 14C-octanoate, 23 male Wistar rats were placed on a gamma camera in a airflow container. Scintigraphic images were taken at regular intervals. The amount of 14CO2 in a regularly replaced hyamine hydroxide solution, capturing CO2 in the outflow air, was counted using liquid scintillation spectrometry. 99mTc gastric retention curves and 14CO2-excretion curves were fitted to their respective data. Three rats underwent the same procedures after administration of atropine. RESULTS: Overall Tr10% (time at which 10% of the original amount of 99mTc remained in the stomach) was 355 +/- 64 minutes; Te90% (time at which 90% of total amount of 14CO2 was excreted) was 325 +/- 106 minutes. Their correlation coefficient was 0.71, R-square 0.50 and P < 0.005. Tr1/2 (50% of original amount of 99mTc remained) was 124 +/- 28 minutes; Te1/2 (50% of total amount of 14CO2 excreted) 114 +/- 32 minutes. Their correlation coefficient was 0.83 with R-square of 0.69 and P < 0.00005. In 12 immobilized animals correlation was even better: correlation coefficient 0.84; R-square 0.71 and P < 0.001 (Tr10% was 388 +/- 117 minutes; Te90% 532 +/- 219 minutes; Tr1/2 of 165 +/- 54 minutes; Te1/2 of 175 +/- 67 minutes). Atropine significantly lengthened all emptying times: 904 +/- 307 and 1461 +/- 684 minutes for Tr10% and Te90%, respectively; and 432 +/- 117 minutes for Tr1/2 and 473 +/- 190 minutes for Te1/2. CONCLUSIONS: We adapted and validated the 14C-octanoate gastric emptying breath test for application in rats.
