Abstract
INTRODUCTION The phenomenon of population ageing is accompanied by increases in the number of elderly haemodialysis patients worldwide. The incidence of frailty is high in the haemodialysis population and is associated with poor clinical outcome. Although several interventions have been developed for use in general haemodialysis patients, the efficacy of such rehabilitation programmes in frail elderly patients on haemodialysis has not been elucidated. Here, we examined whether electrical muscle stimulation (EMS) would show beneficial effects in frail elderly patients on haemodialysis. METHODS AND ANALYSIS This is a randomised, two-period, controlled crossover trial, which will enrol 20 patients. Haemodialysis patients aged ≥65 years and defined as frail (ie, Short Physical Performance Battery score 4-9), will be randomly assigned to either group 1 (EMS intervention beginning in treatment period I, followed by reallocation as controls in treatment period II after a 5-week washout period) or group 2 (opposite schedule) in a 1:1 ratio. The two intervention periods will last 5 weeks each with an intervening washout period of 5 weeks. In the EMS intervention group, the treatment will be applied to the skeletal muscle of the entire lower extremity for 5 weeks, three times/week for 30-40 min during haemodialysis. The primary outcome of this study is the change in quadriceps isometric strength after the interventions. The secondary outcomes are the changes in physical function, physical activity, difficulty in activities of daily living, body composition, cognitive function, depressive symptoms, quality of life, blood test results and the clinical safety and feasibility of EMS therapy. ETHICS AND DISSEMINATION This study has been approved by the institutional review board/ethics committee of Kitasato University Allied Health Sciences. This study will be reported in peer reviewed publications and at conference presentations. TRIAL REGISTRATION NUMBER UMIN000032501.

Abstract
Frailty is significantly associated with bone loss in the general population. However, it is unclear whether this association also exists in patients undergoing hemodialysis who have chronic kidney disease-mineral and bone disorder (CKD-MBD). This study aimed to assess the association between frailty and bone loss in patients undergoing hemodialysis. This cross-sectional study included 214 (90 women, 124 men) Japanese outpatients undergoing maintenance hemodialysis three times per week, with a mean age of 67.1 years (women) and 66.8 years (men). Frailty was defined based on criteria set forth by the Cardiovascular Health Study (CHS)-19 (21.1%) women and 47 (37.9%) men were robust, 41 (45.6%) women and 43 (34.7%) men were pre-frail, and 30 (33.3%) women and 34 (27.4%) men were frail. For bone mass, quantitative ultrasound (QUS) parameters (speed of sound, broadband ultrasound attenuation, stiffness index) of the calcaneus were measured. The association between frailty and QUS parameters was determined separately for women and men using multivariate analysis of covariance (ANCOVA), with adjustments for clinical characteristics including age, body mass index, hemodialysis vintage, diabetes, current smoking, serum albumin, phosphate, corrected calcium, intact parathyroid hormone, and medication for CKD-MBD (vitamin D receptor activator, calcimimetics). ANCOVA revealed that all QUS parameters declined significantly with increasing levels of frailty in both sexes (P < 0.05). In conclusion, frailty (as defined by CHS criteria) should be considered a risk factor for bone loss in patients undergoing hemodialysis.

Abstract
BACKGROUND/AIMS Several clinical practice guidelines recommend regular assessment of physical activity and physical function as part of routine care in hemodialysis patients. However, there is no clear evidence to support these recommendations. We investigated whether the proportion of attendance at a regular program for management of physical activity and physical function can predict all-cause mortality and cardiovascular events in hemodialysis patients. METHODS This retrospective cohort study consisted of 266 hemodialysis patients participating in the management program at least once. Participants were tracked for 3 years after their first attendance at the management program to determine their attendance proportion. The main study outcomes included all-cause mortality and a composite of fatal and nonfatal cardiovascular events. RESULTS Median patient age was 64.5 (interquartile range, 56.8 - 72.0) years, 45% were women, and the median time on hemodialysis was 35.5 (interquartile range, 12.0 - 114.3) months at baseline. Sixty-five patients died over a median follow-up of 79 months. The incidence of cardiovascular events was 60 over a median follow-up of 68 months. Even after adjusting for any of the prognostic models, participants who attended ≤ 75% of sessions (n = 140) had higher risks of mortality (hazard ratio (HR), 1.79; 95% confidence interval (CI): 1.00 - 3.36; P = 0.049) and cardiovascular events (HR, 1.84; 95% CI: 1.07 - 3.48; P = 0.03) than those attending > 75% of sessions (n = 126). CONCLUSION Hemodialysis patients in whom physical activity and physical function could be assessed more regularly had better prognosis than those with only intermittent assessment.

Abstract
Ephedra Herb is an important crude drug; it is used in various Traditional Japanese Medicine (Kampo) formulations. Its significant pharmacological effects have been believed to be attributed to ephedrine and pseudoephedrine, which sometimes induce adverse effects. On the other hand, it has been reported that some of these pharmacological effects are not dependent on ephedrine or pseudoephedrine. Ephedrine alkaloids-free Ephedra Herb extract has been newly developed. It has been reported to have analgesic, anti-influenza, and antimetastatic effects. This clinical trial was aimed at verifying the noninferiority of EFE's safety compared to that of Ephedra Herb extract (EHE) in humans. This was a single-institution, double-blinded, randomized, two-drug, two-stage, crossover comparative study. Twelve healthy male subjects were equally and randomly allocated into two groups: prior administration of EFE (EFE-P) and prior administration of EHE (EHE-P). In Stage 1, EFE and EHE were orally administered to the EFE-P and EHE-P groups, respectively, for six days. After a 4-week washout period, Stage 2 was initiated wherein the subjects were given a study drug different from Stage 1 study drug for six days. Eleven adverse events with a causal relationship to the study drugs (EHE: 8; EFE: 3) were noted; all events were mild in severity. With regard to the incidence of adverse events, EHE and EFE administration, respectively, accounted for 4 cases (out of 12 subjects, similarly below) and 1 case of increased pulse rate (p=0.32) and 3 cases and 1 case of insomnia (p=0.59). Further, there was one case of hot flashes (p=1.00) due to EFE administration and one case of dysuria (p=1.00) due to EHE administration. There were no significant differences in the incidences of adverse events between EHE administration and EFE administration. Therefore, we concluded that EFE is not inferior to EHE in terms of safety.

Abstract
The Bethesda system (TBS) has been used for cervical cytological diagnosis in Japan since 2008. Evaluation of specimen adequacy is the most important aspect of quality assurance and for precise diagnosis in TBS. A systematic review and meta‐analysis were carried out to assess the unsatisfactory specimen rate in the primary cervical cancer screening setting in Japan. Ovid Medline and Ichushi‐Web databases were searched from inception through to May 2017. Prospective and retrospective studies that reported the proportion of unsatisfactory specimens in healthy asymptomatic Japanese women in a cervical cancer screening program were eligible for inclusion; 17 studies were included in the meta‐analysis. The random‐effects model meta‐analysis calculated summary estimates of the unsatisfactory rate of 0.60% (95% confidence interval [CI], 0.18‐1.96%; I2 = 99%) for conventional cytology and 0.04% (95% CI, 0.00‐0.35%; I2 = 99%) for liquid‐based cytology (LBC). However, comparative results between conventional and liquid‐based cytology, based on four direct and nine comparative studies, showed no significant difference (summary odds ratio = 3.5 × 10−2 favoring LBC [95% CI, 6.9 × 10−4‐1.7]; I2 = 98%). In the subgroup analyses and meta‐regressions, use of non‐cotton devices for conventional cytology and use of a particular platform for LBC were associated with lower unsatisfactory rates. Meta‐regression also suggested chronological improvement in unsatisfactory rates for both tests. In Japanese cervical cancer screening programs, conventional cytology remains prevalent. Future research needs to focus on evaluating the impact of screening programs using LBC by comparing the accuracy, performance, and cost‐effectiveness with conventional cytology in the Japanese population.

Abstract
BACKGROUND Dental caries (tooth decay) is one of the most common chronic childhood diseases. Caries prevalence in most industrialised countries has declined among children over the past few decades. The probable reasons for the decline are the widespread use of fluoride toothpaste, followed by artificial water fluoridation, oral health education and a slight decrease in sugar consumption overall. However, in regions without water fluoridation, fluoride supplementation for pregnant women may be an effective way to increase fluoride intake during pregnancy. If fluoride supplements taken by pregnant women improve neonatal outcomes, pregnant women with no access to a fluoridated drinking water supply can obtain the benefits of systemic fluoridation. OBJECTIVES To evaluate the effects of women taking fluoride supplements (tablets, drops, lozenges or chewing gum) compared with no fluoride supplementation during pregnancy to prevent caries in the primary teeth of their children. SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 25 January 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 11) in the Cochrane Library (searched 25 January 2017); MEDLINE Ovid (1946 to 25 January 2017); Embase Ovid (1980 to 25 January 2017); LILACS BIREME Virtual Health Library (Latin American and Caribbean Health Science Information database; 1982 to 25 January 2017); and CINAHL EBSCO (Cumulative Index to Nursing and Allied Health Literature; 1937 to 25 January 2017). We searched the US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform for ongoing trials to 25 January 2017. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA Randomised controlled trials (RCTs) of fluoride supplements (tablets, drops, lozenges or chewing gum) administered to women during pregnancy with the aim of preventing caries in the primary teeth of their children. DATA COLLECTION AND ANALYSIS Two review authors independently screened the titles and abstracts (when available) of all reports identified through electronic searches. Two review authors independently extracted data and assessed risk of bias, as well as evaluating overall quality of the evidence utilising the GRADE approach. We could not conduct data synthesis as only one study was included in the analysis. MAIN RESULTS Only one RCT met the inclusion criteria for this review. This RCT showed no statistical difference on decayed or filled primary tooth surfaces (dfs) and the percentage of children with caries at 3 years (risk ratio (RR) 1.46, 95% confidence interval (CI) 0.75 to 2.85; participants = 938, very low quality of evidence) and 5 years old (RR 0.84, 95% CI 0.53 to 1.33; participants = 798, very low quality of evidence). The incidence of fluorosis at 5 years was similar between the group taking fluoride supplements (tablets) during the last 6 months of pregnancy and the placebo group. AUTHORS' CONCLUSIONS There is no evidence that fluoride supplements taken by women during pregnancy are effective in preventing dental caries in their offspring.

Abstract
BACKGROUND This study investigated whether pachinko play influences the outcome of stroke events, and identified the significant variables affecting outcomes. METHODS We reviewed the medical and imaging records of 2075 consecutive patients with stroke from January 2003 through June 2012. The remaining patients were divided into 2 groups, the pachinko players group (PP) and the non-pachinko players group (NPP). Background factors were recorded on admission. Multivariate logistic regression analysis was used to identify the factors significantly correlated with Glasgow Outcome Scale (GOS) score and risk of death at the time of discharge. RESULTS The PP group exhibited higher prevalence of hypertension and current smoking compared with the NPP group. However, no difference was found in outcomes between the PP and NPP groups. Multivariate analysis identified the dependent predictive variables for GOS as age (adjusted β = -.18, 95% confidence interval [CI]: -.22 to -.14, P <.001), Glasgow Coma Scale (GCS) score on admission (adjusted β = .64, 95% CI: .60 to .68, P <.001), and history of hypertension (adjusted β = -.06, 95% CI: -.10 to -.02, P = .007). Logistic regression analysis showed that age (odds ratio = 1.02, 95% CI: 1.01 to 1.04, P <.001) and GCS score on admission (odds ratio = .72, 95% CI: .69 to .75, P <.001) were significantly associated with death at the time of discharge. CONCLUSIONS Patients with stroke during playing pachinko have higher prevalence of hypertension and higher smoking rate, but pachinko play itself was not a critical factor determining the outcome of patients with stroke in our emergency center.

Abstract
Introduction Previous reviews have indicated the effectiveness of exercise in people undergoing hemodialysis. However, these analyses did not take into account whether the subjects were elderly. We performed a systematic review of the effects of exercise training in elderly people undergoing hemodialysis and updated the evidence of exercise for people undergoing hemodialysis by adding recent research data. Methods We searched 8 electronic databases up to June 2016. Inclusion criteria were as follows: randomized controlled trial, English publication, subjects aged 18 and older undergoing hemodialysis, evaluation of physical function as an outcome of exercise intervention. We defined elderly as age 60 years and older. The main outcomes were exercise tolerance (peak/maximum oxygen consumption) and walking ability (6-minute walk distance). Secondary outcomes were lower extremity muscle strength and quality of life. Results After screening of 10,923 references, 30 comparisons were entered into the analysis. However, because we found only 1 study in which elderly subjects were treated, we could not perform a meta-analysis for these people. For the general population undergoing hemodialysis, supervised exercise training was shown to significantly increase peak/maximum oxygen consumption (standard mean difference, 0.62; 95% confidence interval 0.38-0.87; P < 0.001), 6-minute walk distance (standard mean difference, 0.58; 95% confidence interval 0.24-0.93; P < 0.001), lower extremity muscle strength (standard mean difference, 0.94; 95% confidence interval 0.67-1.21; P < 0.001), and quality of life (standard mean difference, 0.53; 95% confidence interval 0.52-0.82; P < 0.001). Discussion Our analysis on the effectiveness of exercise training in elderly people undergoing hemodialysis as compared with nonelderly people was somewhat inconclusive. Future studies should be carried out for elderly people to identify the most favorable exercise program for this population.

Abstract
Spin selective magnetic hysteresis (SSMH) curves, orbital selective magnetic hysteresis (OSMH) curves and magnetic quantum number selective SSMH curves are obtained for CoFeB/MgO multilayer films by combining magnetic Compton profile measurements and superconducting quantum interference device (SQUID) magnetometer measurements. Although the SQUID magnetometer measurements do not show perpendicular magnetic anisotropy (PMA) in the CoFeB/MgO multilayer film, PMA behavior is observed in the OSMH and SSMH curves for the |m| = 2 magnetic quantum number states. These facts indicate that magnetization switching behavior is dominated by the orbital magnetization of the |m| = 2 magnetic quantum number states.

Abstract
INTRODUCTION As the average age of haemodialysis patients rapidly increases around the world, the number of frail, elderly patients has increased. Frailty is well known to be an indicator of disability and a poor prognosis for haemodialysis patients. Exercise interventions have been safely and successfully implemented for middle-aged or younger patients undergoing haemodialysis. However, the benefits of exercise interventions on elderly patients undergoing haemodialysis remain controversial. The main objective of this study is to systematically review the effects of exercise training on the physical function, exercise capacity and quality of life of elderly patients undergoing haemodialysis, and to provide an update on the relevant evidence. METHODS AND ANALYSES Published randomised controlled trials (RCTs) that assessed the effectiveness of exercise training on haemodialysis patients with respect to physical function, exercise tolerance and quality of life will be included. Bibliographic databases include MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, CINAHL, Web of Science, PsycINFO and PEDro. The risk of bias of the included RCTs will be assessed using the Cochrane Collaboration's tool and TESTEX. The primary outcome will be physical function and exercise tolerance. This review protocol is reported according to the PRISMA-P 2015 checklist. Statistical analysis will be performed using review manager software (RevMan V.5.3, Cochrane Collaboration, Oxford, England). ETHICS AND DISSEMINATION Ethical approval is not required because this study does not include confidential personal data nor does it perform interventions on patients. This review is expected to inform readers on the effectiveness of exercise training in elderly patients undergoing haemodialysis. Findings will be presented at conferences and submitted to a peer-reviewed journal for publication. PROSPERO REGISTRATION NUMBER CRD42015020701.

Abstract
OBJECTIVE Unexpected post-extraction bleeding is often experienced in clinical practice. Therefore, determining the risk of post-extraction bleeding in patients receiving anticoagulant therapy prior to surgery is beneficial. This study aimed to verify whether the HAS-BLED score was useful in predicting post-extraction bleeding in patients taking warfarin. DESIGN Retrospective cohort study. SETTING Department of Oral and Maxillofacial Surgery, Tokyo Women's Medical University. PARTICIPANTS Participants included 258 sequential cases (462 teeth) who had undergone tooth extraction between 1 January 2010 and 31 December 2012 while continuing warfarin therapy. MAIN OUTCOME MEASURE Post-extraction risk factors for bleeding. The following data were collected as the predicting variables for multivariate logistic analysis: the HAS-BLED score, extraction site, tooth type, stability of teeth, extraction procedure, prothrombin time-international normalised ratio value, platelet count and the use of concomitant antiplatelet agents. RESULTS Post-extraction bleeding was noted in 21 (8.1%) of the 258 cases. Haemostasis was achieved with localised haemostatic procedures in all the cases of post-extraction bleeding. The HAS-BLED score was found to be insufficient in predicting post-extraction bleeding (area under the curve=0.548, p=0.867, multivariate analysis). The risk of post-extraction bleeding was approximately three times greater in patients taking concomitant oral antiplatelet agents (risk ratio=2.881, p=0.035, multivariate analysis). CONCLUSIONS The HAS-BLED score alone could not predict post-extraction bleeding. The concomitant use of oral antiplatelet agents was a risk factor for post-extraction bleeding. No episodes of post-extraction bleeding required more than local measures for haemostasis. However, because this was a retrospective study conducted at a single institution, large-scale prospective cohort studies, which include cases of outpatient tooth extraction, will be necessary in the future.

Abstract
BACKGROUND Peritoneal lavage cytology cancer-positive (CY1) is a critical prognostic factor and is taken as representing stage IV in gastric cancer. There is no consensus treatment strategy for CY1-gastric cancer, and the detailed clinicopathological features remain obscure. PATIENTS AND METHODS Among 790 gastric cancer patients between 2005 and 2009, 52 cases of CY1 were identified (6.6%). A multivariate prognostic model was applied to the univariate prognostic factors to identify independent prognostic factors and factors associated with long-term survival in CY1-gastric cancer. RESULTS (1) Five-year overall survival (OS) was 17.6% in CY1-gastric cancer as compared with 93.9% in CYX and 77.7% in CY0 (77.7%), where tumors with pT2 or beyond were included in 11% of CYX, 73% of CY0, and 98% of CY1 cases. (2) On univariate analysis, factors associated with a negative prognosis were the presence of peritoneal dissemination (p = 0.029) and high preoperative serum albumin (p = 0.011) in CY1-gastric cancer. The multivariate Cox proportional hazards and logistic regression model using propensity score identified preoperative albumin as a critical independent prognostic indicator. (3) Long-term survivors were identified and, were often characterized by long-term postoperative adjuvant treatment. CONCLUSION Reduced preoperative serum albumin and absence of peritoneal dissemination may be predictive factors for long-term survival in patients with advanced gastric cancer with positive cytology test. Long-term postoperative adjuvant therapy might improve survival of patients with CY1.

Abstract
OBJECTIVE The study group for sick house syndrome (SHS) in Japan has proposed the classifications, definition and diagnostic criteria for chemical-associated SHS. We compared the physicians' diagnoses to the diagnoses based on the patients' interview sheets including diagnostic criteria only. METHODS We examined 287 patients with complaints of SHS-like symptoms. We also checked determinations of chemical substances in the patients' homes. RESULTS A total of 76.0% of the patients were diagnosed as having SHS. Physicians diagnosed 87.6% of those patients as having chemical-associated SHS based on SHS classifications, definition and diagnostic criteria. Based on the patients' interview sheets, 50.3% of the patients who were diagnosed as chemical-associated SHS corresponded to the diagnostic criteria. The 51 of those chemical-associated SHS patients had answered that the chemical substance levels in their homes had been checked, and 20 of those patients answered that at least one of the chemical substance levels was above that set in the guideline by the Japanese Ministry of Health, Labour and Welfare. CONCLUSIONS Physicians should use all of the classifications, definition and diagnostic criteria. Even if the chemical levels in the home are under the guideline levels, the diagnosis of chemical-associated SHS should not be excluded.

Abstract
The factors conferring the increased malignancy on lung adenocarcinoma with micropapillary component (AC-MPC) remain to be elucidated. On proteomics based on 2-dimensional gel electrophoresis, 19 proteins differentially expressed by more than 1.5-fold between AC-MPC and conventional adenocarcinoma (CAC); in particular, vimentin, one of the proteins, was 3.5-fold up-regulated in AC-MPC. Subsequent semi-quantitative investigation by immunohistochemistry with large cohorts comprised 101 AC-MPC and 119 CAC, respectively, of different stages revealed that vimentin was expressed in MPC of 95 (94.1%) AC-MPC and the expression scores were higher than those of well- and moderately differentiated CAC, as well as the background non-MPC of the AC-MPC (P < 0.0001), but not significantly different from those of poorly differentiated CAC (P = 0.561). Even within the AC-MPC entity, higher vimentin expression was correlated with more frequent vascular invasion and more advanced node metastasis (P < 0.02), and multivariate analysis showed that high vimentin expression and worse node statuses were independent indicators of adverse prognosis (P < 0.048). In conclusion, vimentin expression is prevalent and markedly up-regulated in MPC, which might reflect the biological essence of poorer differentiation or dedifferentiation of MPC, and this might have a role in the acquisition and increase of invasiveness and consequent more malignant nature of MPC.

Abstract
Systemic abrogation of TGF-β signaling results in tumor reduction through cytotoxic T lymphocytes activity in a mouse model. The administration of polysaccharide-Kureha (PSK) into tumor-bearing mice also showed tumor regression with reduced TGF-β. However, there have been no studies regarding the PSK administration to cancer patients and the association with plasma TGF-β. PSK (3 g/day) was administered as a neoadjuvant therapy for 2 weeks before surgery. In total, 31 advanced gastric cancer (AGC) patients were randomly assigned to group A (no neoadjuvant PSK; n=14) or B (neoadjuvant PSK therapy; n=17). Plasma TGF-β was measured pre- and postoperatively. The allocation factors were clinical stage (cStage) and gender. Plasma TGF-β ranged from 1.85-43.5 ng/ml (average, 9.50 ng/ml) in AGC, and 12 patients (38.7%) had a high value, >7.0 ng/ml. These patients were largely composed of poorly-differentiated adenocarcinoma with pathological stage III/IV. All the six elevated cases in group B showed a significant reduction of plasma TGF-β (from 21.6 to 4.5 ng/ml, on average), whereas this was not exhibited in group A. The cases within the normal limits of TGF-β remained unchanged irrespective of PSK treatment. Analysis of variance showed a statistically significant reduction in the difference of plasma TGF-β between groups A and B (P=0.019). PSK reduced the plasma TGF-β in AGC patients when the levels were initially high. The clinical advantage of PSK may, however, be restricted to specific histological types of AGC. Perioperative suppression of TGF-β by PSK may antagonize cancer immune evasion and improve patient prognosis in cases of AGC.

Identification of EGFR expression status association with metastatic lymph node density (ND) by expression microarray analysis of advanced gastric cancer. Cancer Med 2014; 4:90-100.

Abstract
Metastatic lymph node density (ND) has been reproducibly proven to be a prognostic factor in gastric cancer. The molecular mechanisms that underlie this aggressiveness are underexplored. Here, we aimed to identify molecules associated with this unique phenotype. Tumor specimens from patients with stage III gastric cancer with high or low ND (n = 4 for both) were compared at the mRNA level using Affymetrix microarray (harboring 54,675 genes). The expression data were prioritized, and genes that correlated with ND were selected. Ultimately, the EGFR was validated as such a candidate molecule in patients with primary advanced gastric cancer who underwent standard treatment (n = 167). Expression data of the microarray were prioritized based on gene expression ratio and frequency of gene expression. The first priority genes to be selected were genes that are known to be amplified in cancer, which included NKX2.1, CHST9, CTNND2, SLC25A27, FGFR2, EGFR, and PTGER1. Of these genes, the EGFR gene was of particular interest. EGFR expression in primary gastric cancer was examined using immunohistochemistry (IHC). The Student's t-test elucidated a significant difference in EGFR expression between IHC 2+/3+ and IHC 1+ according to ND (P = 0.0035). The Chi-square test also indicated a significant difference between high and low levels of EGFR immunohistochemical staining (IHC2+/3+ and IHC1+, respectively) and ND status (P = 0.0023). According to the least squares method, as ND increased, the risk that EGFR staining levels changed from IHC 1+ to IHC 2+ also increased. In this study, we determined that high EGFR expression may underlie the aggressive mechanism of advanced gastric cancer with high ND.

Abstract
Purpose To compare the efficacy, predictability, safety, and induced higher-order aberrations (HOAs) between wavefront-guided and non-wavefront-guided photorefractive keratectomy (PRK). Methods The Cochrane Central Register of Controlled Trials, PubMED, and EMBASE were searched for randomized controlled trials. Trials meeting the selection criteria were quality appraised, and data was extracted by 2 independent authors. Measures of association were pooled quantitatively using meta-analytical methods. Comparisons between wavefront-guided and non-wavefront-guided ablations were made as pooled odds ratios (ORs) or weighted mean differences. The pooled ORs and 95% confidence intervals (CIs) were computed for efficacy, safety, and predictability. The weighted mean differences and 95% CIs were used to compare induced HOAs. Results The study covered five trials involving 298 eyes. After wavefront-guided PRK, the pooled OR of achieving an uncorrected distance visual acuity of 20/20 (efficacy) was 1.18 (95% CI, 0.53–2.60; p = 0.69), the pooled OR of achieving a result within ±0.50 diopter of the intended target (predictability) was 0.86 (95% CI, 0.40–1.84; p = 0.70). No study reported a loss of 2 or more lines of Snellen acuity (safety) with either modality. In eyes with wavefront-guided PRK, the postoperative trefoil aberrations (mean difference −0.02; 95% CI, −0.03 to −0.00; p = 0.03) were significantly lower. There were no significant differences between the two groups in the postoperative total HOAs (mean difference −0.04; 95% CI, −0.23 to 0.14; p = 0.63), spherical (mean difference 0.00; 95% CI, −0.08 to 0.09; p = 0.93), and coma (mean difference −0.06; 95% CI, −0.14 to 0.03; p = 0.20) aberrations. Conclusions According to the meta-analysis, wavefront-guided PRK offered no advantage in efficacy, predictability, or safety measures over non-wavefront-guided PRK, although it may have induced fewer trefoil aberrations.

Abstract
BACKGROUND Trigeminal nerve block is widely used for trigeminal neuralgia (TN), though with much painful procedure and potential serious complications. The pain of TN occurs most frequently in the second and the third divisions of the trigeminal nerve, which are distributed in intraoral mucous membrane as well as face skin. Here, we examined the response to intraoral application of 8% lidocaine (LDC) in patients with oral TN pain in a double-blind, placebo (PBO)-controlled crossover study. METHODS Twenty-four outpatients with oral TN pain were randomized to receive intraoral application of either 8% LDC or saline PBO to the painful area. Following 7-days period, patients were crossed over to receive the alternative treatment. The pain was assessed with a numerical rating scale (NRS) before and 15 minutes after treatment. Patients used a descriptive scale to grade pain outcome and were asked to note any recurrence and the latency for recurrence after therapy. RESULTS Intraoral LDC, but not PBO, significantly decreased the NRS from 5 (4, 8) (median [25, 75 percentiles]) to 1 (0, 4) (P = 0.001). Of the 24 patients, 19 described marked or moderate relief of pain after LDC but only three described the same after PBO application. The effect of LDC and PBO persisted for 2.8 (0.3, 3.0) and 0 (0, 0) hours, respectively. CONCLUSIONS Intraoral application of 8% LDC produced prompt analgesia without serious side effects in patients with TN who presented with severe intraoral pain.
