    Full Text Available OBJECTIVE: Conduct a prospective randomized single-blind comparison of two nephrostomy catheter designs, evaluating specifically intraoperative placement and postoperative comfort. MATERIALS AND METHODS: The single-blind, prospective randomized trial was conducted with institutional review board approval. All patients undergoing percutaneous nephrolithotomy who gave informed consent were randomized to placement of either a Boston Scientific Flexima 8.3F pigtail nephrostomy tube #27-180 (PIG or a Boston Scientific 8.2F nephroureteral stent #410-126 (NUS. Randomization was concealed from the surgeon until time of placement. Subjective intraoperative placement characteristics were rated by the surgeon on a scale of 1 = excellent, 2 = fair, 3 = good and 4 = poor. The patient's postoperative pain intensity was evaluated with a Visual Analog Pain Score (0 = no pain to 10 = worst pain. RESULTS: Nine patients were randomized to each group. The PIG group was rated significantly better than the NUS group with regards to ease of placement (p = 0.007 and radiopacity of the tube (p = 0.007 by surgeon. Visual analog pain scores on postoperative day one, was significantly lower in the PIG group (mean = 2+/-2 than the NUS group (mean = 5+/-1 (p = 0.004. The mean amount of intra-venous morphine equivalent given in the PIG group (mean = 1+/4 Eq morphine was less on average compared to the NUS group (mean = 6+/13 Eq morphine, but the differences did not reach statistical significance (p = 0.06. CONCLUSIONS: Following percutaneous nephrolithotomy, use of a small pig-tail nephrostomy tube results in greater ease of placement and less postoperative pain than a nephroureteral catheter.

    Full Text Available Abstract Background When planning a randomized controlled trial (RCT, investigators must select randomization and allocation procedures based upon a variety of factors. While third party randomization is cited as being among the most desirable randomization processes, many third party randomization procedures are neither feasible nor cost-effective for small RCTs, including pilot RCTs. In this study we present our experience with a third party randomization and allocation procedure that utilizes current technology to achieve randomization in a rapid, reliable, and cost-effective manner. Methods This method was developed by the investigators for use in a small 48-participant parallel group RCT with four study arms. As a nested study, the reliability of this randomization procedure was prospectively evaluated in this cohort. The primary outcome of this nested study was the proportion of subjects for whom allocation information was obtained by the Research Assistant within 15 min of the initial participant randomization request. A secondary outcome was the average time for communicating participant group assignment back to the Research Assistant. Descriptive information regarding any failed attempts at participant randomization as well as costs attributable to use of this method were also recorded. Statistical analyses included the calculation of simple proportions and descriptive statistics. Results Forty-eight participants were successfully randomized and group allocation instruction was received for 46 (96% within 15 min of the Research Assistant placing the initial randomization request. Time elapsed in minutes until receipt of participant allocation instruction was Mean (SD 3.1 +/− 3.6; Median (IQR 2 (2,3; Range (1–20 for the entire cohort of 48. For the two participants for whom group allocation information was not received by the Research Assistant within the 15-min pass threshold, this information was obtained following a second

    Full Text Available Abstract Background We assessed the hemodynamic performance of various prostheses and the clinical outcomes after aortic valve replacement, in different age groups. Methods One-hundred-and-twenty patients with isolated aortic valve stenosis were included in this prospective randomized randomised trial and allocated in three age-groups to receive either pulmonary autograft (PA, n = 20 or mechanical prosthesis (MP, Edwards Mira n = 20 in group 1 (age 75. Clinical outcomes and hemodynamic performance were evaluated at discharge, six months and one year. Results In group 1, patients with PA had significantly lower mean gradients than the MP (2.6 vs. 10.9 mmHg, p = 0.0005 with comparable left ventricular mass regression (LVMR. Morbidity included 1 stroke in the PA population and 1 gastrointestinal bleeding in the MP subgroup. In group 2, mean gradients did not differ significantly between both populations (7.0 vs. 8.9 mmHg, p = 0.81. The rate of LVMR and EF were comparable at 12 months; each group with one mortality. Morbidity included 1 stroke and 1 gastrointestinal bleeding in the stentless and 3 bleeding complications in the MP group. In group 3, mean gradients did not differ significantly (7.8 vs 6.5 mmHg, p = 0.06. Postoperative EF and LVMR were comparable. There were 3 deaths in the stented group and no mortality in the stentless group. Morbidity included 1 endocarditis and 1 stroke in the stentless compared to 1 endocarditis, 1 stroke and one pulmonary embolism in the stented group. Conclusions Clinical outcomes justify valve replacement with either valve substitute in the respective age groups. The PA hemodynamically outperformed the MPs. Stentless valves however, did not demonstrate significantly superior hemodynamics or outcomes in comparison to stented bioprosthesis or MPs.

    Full Text Available Abstract Background Personal digital assistants (PDA offer putative advantages over paper for collecting research data. However, there are no data prospectively comparing PDA and paper in the emergency department. The aim of this study was to prospectively compare the performance of PDA and paper enrollment instruments with respect to time required and errors generated. Methods We randomized consecutive patients enrolled in an ongoing prospective study to having their data recorded either on a PDA or a paper data collection instrument. For each method, we recorded the total time required for enrollment, and the time required for manual transcription (paper onto a computer database. We compared data error rates by examining missing data, nonsensical data, and errors made during the transcription of paper forms. Statistical comparisons were performed by Kruskal-Wallis and Poisson regression analyses for time and errors, respectively. Results We enrolled 68 patients (37 PDA, 31 paper. Two of 31 paper forms were not available for analysis. Total data gathering times, inclusive of transcription, were significantly less for PDA (6:13 min per patient compared to paper (9:12 min per patient; p Conclusion Using a PDA-based data collection instrument for clinical research reduces the time required for data gathering and significantly improves data integrity.

    Full Text Available Objectives: The objective of the study was to evaluate the efficacy of local anesthetic infiltration, in decreasing the discomfort experienced by patients undergoing trans-rectal ultrasound (TRUS guided biopsy of prostate. Materials and methods: Between January 2002 and February 2003, we investigated consecutively, asymptomatic men, suspected of having prostatic cancer. About 39 patients were randomized to receive 10 ml of 2% Lidocaine periprostatic block + intrarectal Lidocaine gel (group 1 = 20, or intarectal Lidocaine gel only (group 2 = 19 during prostatic biopsy. Immediately following the TRUS-guided biopsy, patients were asked to grade the pain they experienced using the 11-point visual analogue score (VAS. Results: The mean pain score in the patients of group 1 were significantly lower than the patients of group 2 ( P < 0.001, suggesting that periprostatic block produced a significant reduction in the perceived pain. Conclusions: Local anesthetic infiltration by TRUS-guided injection of Lidocaine is effective for decreasing pain associated with prostatic biopsy.

    AIM: To evaluate the efficacy of 5 compared to 10 granulocyteaphaeresis sessions in patients with active steroid-dependent ulcerative colitis.METHODS: In this pilot, prospective, multicenter randomized trial, 20 patients with moderately active steroid-dependent ulcerative colitis were randomized to 5 or 10 granulocyteaphaeresis sessions. The primary objective was clinical remission at wk 17. Secondary measures included endoscopic remission and steroid consumption.RESULTS: Nine patients were randomized to 5 granulocyteaphaeresis sessions (group 1) and L1 patients to 10 granulocyteaphaeresis sessions (group 2). At wk 17, 37.5% of patients in group 1 and 45.45% of patients in group 2 were in clinical remission. Clinical remission was accompanied by endoscopic remission in all cases.Eighty-six percent of patients achieving remission were steroid-free at wk 17. Daily steroid requirements were significantly lower in group 2. Eighty-nine per cent of patients remained in remission during a one year follow-up. One serious adverse event, not related to the study therapy, was reported.CONCLUSION: Granulocyteaphaeresis is safe and effective for the treatment of steroid-dependent ulcerative colitis. In this population, increasing the number of aphaeresis sessions is not associated with higher remission rates, but affords a significant steroid-sparing effect.

    Full Text Available BACKGROUND: To assess the efficacy of rectal diclofenac suppository in patients undergoing elective laparoscopic cholecystectomy surgeries in management of postoperative pain, in reduction of intra operative opioid requirement and in prolongation of postoperative anal gesic initiation time. OBJECTIVES: This prospective randomized single blinded clinical trial evaluates the efficacy of rectal diclofenac suppository for the management of postoperative pain. MATERIALS AND METHODS: 100 patients undergoing elective laparosco pic cholecystectomy surgeries were randomized into two groups, Group 1 patients receiving 100mg diclofenac rectal suppository after induction of general anaesthesia, Group 2 patients does not receive any diclofenac rectal suppository. Intra operative hemod ynamic monitoring, post - operative VAS score and adverse reactions were recorded over period of 24 hrs. Intra operative opioid (fentanyl was repeated when heart rate and blood pressure variability of more than 20% from base line are noted. Post operatively if VAS score is more than 4 rescue analgesia with inj. Tramadol is given intramuscularly. RESULTS: Administration of single dose of rectal diclofenac had statistically significant reduction in VAS score post operatively compared to control group, reduced requirement of intra operative opioids (fentanyl. Post - operative rescue analgesia initiation time is prolonged in group 1 mean 9.56 hrs compared to group 2, mean 0.72 hrs (p - 0.000. CONCLUSION: Rectal Diclofenac used in laparoscopic cholecystectomy cases provide adequate, effective prolonged analgesia in the post - operative period with good safety profile

    Combined surface electromyography (sEMG) and visual analogue scale (VAS) pain assessment was performed on randomly assigned adults following tonsillectomy to research the effect of fibrin sealant (Group 1, n = 25), CO(2) laser (Group 2, n = 18) and electrocoagulation (Group 3, n = 40) on postsurgical pain. Timing and amplitude of sEMG activity of masseter, infrahyoid and submandibular muscles were measured during swallowing simultaneously with VAS assessment and compared to normative database. Postsurgical electric activity of masseter and infrahyoid was significantly higher in comparison with normative database. sEMG and VAS data showed that tonsillectomy ended with fibrin sealant caused less pain than laser or electrocoagulation techniques with no correlation between the VAS score and duration of swallows. Tonsillectomy affects muscle activity significantly by involving additional muscles (infrahyoid) in swallowing. Combined sEMG and VAS data indicated electrocautery as the most painful, laser as less painful, and fibrin sealant as the least painful technique.

    2015-08-01

    Full Text Available BACKGROUND: Utility of succinylcholine for rapid sequence induction is a common practice for more than last 50 years. The ED 95 dose of succinylcholine is 0.3mg/kg. Regularly 2 - 3 times ED 95 doses of non - depolarizing muscle relaxants are being used for tracheal intubation, but succinylcholine is being used traditionally in a dose of 1mg/kg which is more than 3.5 times ED 95. However, according to the available literature evidence doses as smal l as 0.4 mg /kg may also provide clinically acceptable intubating conditions with the possibility of earlier return of neuromuscular function which avoids critical hemoglobin desaturation in unanticipated difficult airway& CVCI situations. We did a study to evaluate the ease of tracheal intubation with low doses of succinylcholine in Indian population. AIM: To evaluate tracheal intubating conditions and serum potassium levels with different doses of succinylcholine. DESIGN: A prospective randomized double bli nd comparative study. METHODS: 80 patients belonging to ASA PS I&II were randomly divided into 4 groups A,B,C&D who received 0.5mg/kg,0.6mg/kg,0.7mg/kg& 1mg/kg of succinylcholine respectively. All the patients were pre - medicated with Tab. Alprazolam 0.25 mg PO previous night and fentanyl 1mcg/kg 5 min before induction, induced with sleep dose of thiopentone followed by administration of test drug. After 1 min , 3yrs experienced anesthesiologist attempted tracheal intubation& assessment of intubating conditions w ere done using Cooper& colleagues criteria. N - M effects were monitored preoperatively and up to 3 min after dug administration. Haemodynamic parameters& serum potassium were measured preoperatively , continued up to 5 min & 1 hour after drug administration res pectively. RESULTS: Clinical intubation cumulative scores in GROUP A were significantly different from other GROUPS ( B, C, D with ( p<0.05 on ANOVA. N - M monitoring has revealed significant twitch height depression in Group D

    Objectives: Statins by their anti-inflammatory and endothelial stabilizing effect can be beneficial in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH). The present study was done to evaluate the effect of rosuvastatin on pulmonary functions and quality of life (QOL) in patients with concomitant COPD and PH. Materials and Methods: It was a prospective, randomized, double-blind, placebo-controlled, study conducted in patients with COPD and PH. A total of sixty patients were assigned to receive either rosuvastatin 10 mg or placebo once a day in addition to their conventional treatment for 12 weeks. Routine blood investigations, pulmonary functions, echocardiogram, exercise capacity, and QOL using a questionnaire were assessed at the baseline and after 12 weeks. Results: In patients of rosuvastatin group, there was a statistically significant increase in peak expiratory flow rate (PEFR) (P = 0.04) but no significant change in other pulmonary functions: Forced vital capacity (FVC), forced expiratory volume at 1 s (FVC, FEV1, FEV1/FVC), and echocardiogram parameters. There was a significant increase in 6-min walk test (6-min walk distance) (P = 0.03) at the end of 12 weeks. On comparing with placebo, rosuvastatin showed a significant reduction (P = 0.045) in COPD exacerbations while adverse effects did not differ. Conclusion: Statins have a favorable effect on patients with COPD and PH regarding the improvement in PEFR, COPD exacerbations, and exercise capacity. Such effects can be beneficial in these patients and more so in patients with concomitant coronary artery disease or hyperlipidemia where long-term benefits of statins have been established.

    Background: Cataract surgery when performed under general anesthesia, especially without neuromuscular blocking agents, eccentric position of the eye has been reported. However, no evidence exists for the need and optimal dose of neuromuscular blocking agents for surgical reasons when the anesthetic management may be done without its need. We hypothesize that the minimal dose atracurium may accomplish the surgical requirement of cataract surgery in children. Materials and Methods: After ethical committee approval, this double-blind, prospective, randomized study was conducted in children scheduled for cataract surgery under general anesthesia. Anesthesia was induced in a standardized manner and using laryngeal mask airway. The patients were randomized into four groups of 55 patients each and atracurium was administered as per group allocation: Group 0: No atracurium was administered; Group 50: Received atracurium at 50% dose of ED95; Group 75: Received atracurium at 75% dose of ED95; Group 100: Received atracurium of 100% dose of ED95. Surgeon was asked to grade surgical condition just after the stab incision in the cornea. The primary outcome variable included the need of atracurium supplementation based on grading of surgical conditions by the operating surgeon who was blinded to the randomized group. Results: The need of atracurium due to unacceptable surgical conditions based on surgeon satisfaction score was statistically significant when compared among the groups being maximum in Group 0 (P < 0.001). Also, the surgeon satisfaction score was statistically significant among the groups (P < 0.0001) with the least satisfaction in Group 0. The laryngeal mask airway (LMA) insertion score was statistically significant in the four groups (P - 0.001). However, number of attempts for LMA placement was comparable among the four groups (P - 0.766). Conclusion: We conclude that a balanced anesthetic technique including atracurium provided better surgical condition for

    Prevention of surgical site infections and the reduction of wound-related complication rates have become increasingly emphasized by hospital task groups and government agencies given the degree of economic burden it places on the health care system. Platelet-rich plasma (PRP) contains growth factors and other biomolecules that promote endogenous microbicidal activity. We hypothesized that PRP would help prevent postoperative infection and delayed wound healing (DWH). We randomized patients having foot or ankle surgery to the treatment group receiving intraoperative PRP (applied to operative field) and platelet-poor plasma at closing (PPP, on the sutured skin) or the control group (no PRP/PPP). The incidence of deep surgical site infection and DWH (collectively called endpoints) was compared between groups (n = 250/group). PRP had a mean 5.3-fold platelet concentration compared to whole blood, with concentrated white blood cells. Mean age (±SD) of patients was 52 years (±15), 65% were women. Minor and major operative procedures were included. Patients were followed for 60 days. Seventy controls had PRP prepared for assay of growth factors. Procedure mix, ASA scores, mean operative times, and comorbidity mix were similar between groups. The primary result was no difference in number of endpoints between groups: 19 patients in the PRP group (7.6%) versus 18 controls (7.2%). Endpoints were deep surgical site infections in 2 PRP/PPP patients and 1 control, and DWH in 17 PRP/PPP patients and 17 controls. Analysis of PRP samples revealed a large variation in growth factor concentrations between patients. Intraoperative application of PRP/PPP did not reduce the incidence of postoperative infection or DWH. Growth factor profiles varied greatly between patients, suggesting that the potentially therapeutic treatment delivered was not consistent from patient-to-patient.

    Full Text Available OBJECTIVE: In this clinical trial, we aimed to compare three means of performing chronic hemodialysis in patients with contra-indication to systemic heparinization. METHODS: This open-label monocentric randomized « n-of-one » trial, conducted in a single tertiary care center, recruited chronic hemodialysis patients with a contra-indication to systemic heparinization for at least 3 consecutive sessions. All patients underwent hemodialysis with an AN69ST dialyzer, and were administered three alternative dialysis procedures in a random sequence: intermittent saline flushes, constant saline infusion, or pre-dialysis heparin coating of the membrane. The primary outcome was the need to interrupt the dialysis session because of clotting events due to either (i a complete coagulation of the circuit; (ii a partial coagulation of the circuit; (iii a>50% rise over baseline in the venous pressure. RESULTS: At the end of the inclusion period (May, 2007 to December, 2008, the number of patients to include (n=75 was not reached: only 46 patients were included and underwent randomization. The study was terminated, and statistical analysis took into account 224 hemodialysis sessions performed in 44 patients with analyzable data. Heparin adsorption was associated with a significant reduction of the need to interrupt the dialysis session because of clotting events: odds ratio 0.3 (CI 95% 0.2 to 0.6; p3 h dialysis sessions and for having complete blood restitution. There were no significant effects of the dialysis procedure on weight loss, online ionic dialysance, and adverse events. CONCLUSION: Heparin-coated AN69ST dialysis membrane is a safe and effective method to avoid or delay per-dialytic clotting events in patients with contra-indication to systemic anticoagulation. However, results are not generalizable safely to patients with active bleeding, since weak heparinemia, not assessed in this study, may occur. TRIAL REGISTRATION: ClinicalTrials.gov NCT

    Tooth extraction is one of the most commonly performed procedures in dentistry. It is usually a traumatic procedure often resulting in immediate destruction and loss of alveolar bone and surrounding soft tissues. Various instruments have been described to perform atraumatic extractions which can prevent damage to the paradental structures. Recently developed physics forceps is one of the instruments which is claimed to perform atraumatic extractions. The aim of the present study was to compare the efficacy of physics forceps with conventional forceps in terms of operating time, prevention of marginal bone loss & soft tissue loss, postoperative pain and postoperative complications following bilateral premolar extractions for orthodontic purpose. In this prospective split-mouth study, outcomes of the 2 groups (n = 42 premolars) requiring extraction of premolars for orthodontic treatment purpose using Physics forceps and Conventional forceps were compared. Clinical outcomes in form of time taken, loss of buccal soft tissue and buccal cortical plate based on extraction defect classification system, postoperative pain and other complication associated with extraction were recorded and compared. Statistically significant reduction in the operating time was noted in physics forceps group. Marginal bone loss and soft tissue loss was also significantly lesser in physics forceps group when compared to conventional forceps group. However, there was no statistically significant difference in severity of postoperative pain between both groups. The results of the present study suggest that physics forceps was more efficient in reducing operating time and prevention of marginal bone loss & soft tissue loss when compared to conventional forceps in orthodontically indicated premolar extractions.

    Background In clinical studies there is still a lot of controversy about the increased anterior and rotational stability between double-bundle (DB) and single-bundle (SB) anterior cruciate ligament (ACL) reconstruction. The aim of this study was to evaluate the clinical results of four-tunnel DB ACL reconstruction.Methods Sixty-four consecutive patients with ACL ruptures from May 2005 to May 2006 were randomly assigned into two groups: 32 cases for SB ACL reconstruction and 32 cases for DB ACL reconstruction. Clinical data, including KT 2000, Biodex test, Lysholm score, Tegner score and IKDC score, were prospectively collected until at least 10 months post-operative.Results The average values of KT 2000 were (1.47±1.17) mm and (1.68±1.14) mm for the SB and DB ACL reconstruction groups at 30° of knee flexion (P >0.05), and were (1.04±0.98) mm and (1.13±0.98) mm at 90° of knee flexion (P>0.05). There were also no significant differences in Lysholm score, Tegner score, IKDC score and Biodex test scores between the two groups (P>0.05). The operation time of DB ACL reconstruction was 20 minutes longer than the SB ACL reconstruction (P<0.05)Conclusion Double bundle ACL reconstructions have no obvious clinical advantages over single bundle ACL reconstructions.

    Refractory status epilepticus (RSE) is a life-threatening condition that requires immediate and aggressive treatment. Unfortunately, sometimes standard antiepileptic treatment is insufficient. Furthermore, alternative therapeutic options are limited by low evidence of efficacy. The primary objective of this study was to evaluate the effects of the novel drug candidate, NS1209 versus third-line standard treatment (phenytoin/valproate) for RSE. Having not reached the study end-points, the purpose of this paper is to discuss the challenges that are encountered in conducting a controlled study of RSE. This was a phase II, prospective, multicentre, single-blinded, randomized clinical trial and included patients to two separate protocols for convulsive and non-convulsive RSE (NS1209-006 and NS1209-007). In total, 28 patients were included and 14 patients were exposed to NS1209. At study conclusion, the study was insufficiently powered to detect any statistically significant difference between the two treatment groups. This was especially true for the convulsive RSE protocol. We conclude that high-quality studies in RSE are difficult to conduct owing to a number of ethical and practical problems associated with this critical illness. Challenges for further studies are discussed.

    The clinical safety and efficacy of a transmucosal oral spray (TMOS) formulation of meloxicam was evaluated for the control of pain and inflammation associated with osteoarthritis in dogs. A total of 280 client-owned dogs were enrolled at fourteen veterinary clinics: there were 187 dogs in the meloxicam TMOS group and 93 in the placebo control group. Dogs received placebo or treatment spray once daily for twenty-eight days. Improvement in signs of osteoarthritis was measured using client-specific outcome measures (CSOM) made at days 14 and 28 and veterinary assessments of lameness and pain on palpation made at day 28. A significantly higher number of dogs in the meloxicam TMOS group were treatment successes at 28 days (72.6%) compared with the placebo group (46.9%), based on CSOM scores. Total CSOM scores were significantly lower in the meloxicam TMOS-treated group compared with the placebo group at both 14 and 28 days. Differences between treatment groups were not observed in veterinary assessments. Gastrointestinal effects of meloxicam were observed in some animals. Meloxicam TMOS was found to be safe and effective in dogs for the control of pain and inflammation associated with osteoarthritis.

    This study focused on a clinically relevant healthcare problem in the military: acute soft tissue wounds, or blisters. The trial was a prospective, controlled, randomized two-arm study evaluating the efficacy of a bioelectric dressing, Procellera®, applied topically two to three times per week for 2 weeks to blisters developed in Ranger trainees during training at Fort Benning, Georgia. A total of 80 US Army Ranger recruits with blister wounds below the knee were randomly assigned to one of two treatment groups (n = 40/group). The primary goal was to assess the clinical efficacy (rate of healing) of administered Procellera in conjunction with the standard-of-care (SOC) treatment, moleskin and Tegaderm ®, on the healing rate of blisters compared with the SOC treatment alone. The secondary end points for efficacy were the quantities of wound fluid biomarkers and bacterial bioburden. The tertiary end point was assessment of pain in the treatment group compared with that of the control group during the 2-week study. The results showed no statistical difference between the SOC and SOC+Procellera groups in wound healing and pain. Wound fluid was reported for 24 participants (64.9%) in the SOC group and 21 participants (56.8%) in SOC+Procellera group at the baseline measurement (ρ = .475); however, the wounds were devoid of fluid on follow-up visits. The mild nature of the wounds in this study was apparent by the low pain scores at the beginning of the study, which disappeared by the follow-up visits. The average wound sizes were 2.2cm2 and 1.5cm2 for the SOC and SOC+Procellera groups, respectively. This trial protocol should be conducted on open softtissue wounds in severe heat. To our knowledge, this is the first clinical study conducted within the US Army Rangers training doctrine. 2017.

    To compare clinical performance of a transparent absorbent acrylic dressing (3M Tegaderm Absorbent Clear Acrylic Dressing ]TAAD[; 3M Company, St Paul, MN) and a hydrocolloid dressing (HD ]DuoDERM CGF, ConvaTec, ER Squibb & Sons, Princeton, NJ[) in the management of Stage II and shallow Stage III pressure ulcers. Prospective, open-label, randomized, comparative, multisite clinical evaluation. Patients were followed up for a maximum of 56 days or until their ulcer healed. At weekly intervals, investigators conducted wound assessments and dressing performance evaluations. Wound care clinics, home care, and long-term care. Thirty-five patients received the TAAD, and 37 received the HD. Dressing performance assessments, patient comfort, dressing wear time, and wound healing were measured. The majority of investigator assessments favored the TAAD. Considerations given included the ability to center dressings over the ulcer (P = .005), ability to assess the ulcer before (P < .001) and after (P < .001) absorption, barrier properties (P = .039), patient comfort during removal (P < .001), overall patient comfort (P = .048), conformability before (P = .026) and after (P = .001) absorption, ease of removal (P < .001), nonadherence to wound bed (P < .001), residue in the wound (P = .002), residue on periwound skin (P < .001), and odor after absorption (P = .016). Overall satisfaction favored the TAAD (P < .001), and a high value was placed on its transparent feature (P < .001). Mean (SD) wear time for the TAAD was 5.7 (2.55) days compared with 4.7 (2.29) days for the HD (P = .086). This 1-day difference in wear time was clinically noticeable by the investigators (P = .035). Wound closure for the 2 dressing groups was nearly identical (P = .9627). Performance results favored the TAAD over the HD as standard treatment for Stage II and shallow Stage III pressure ulcers.

    Full Text Available AIM AND OBJECTIVES: The present study aims to evaluate the clinical efficacy of clonidine as an adjuvant to General anaesthesia in elective faciomaxillary surgery. Faciomaxillary surgery is generally long duration surgery. Bleeding is expected to be more. As an anesthetist our main aim is to reduce the bleeding and make the patient more hemodynamically stable, so there is always a need to decrease heart rate(H.R., blood pressure (B.P. and prevent hemodynamic stress response to intubation, extubation and intraoperatively. MATERIAL AND METHODS: This prospective, randomized, double-blind controlled study was conducted on 60 male adults of ASA Grade I & II scheduled for elective faciomaxillary surgery under General anaesthesia. After taking consent from the institutional ethical committee patients were divided into 2 groups comprising 30 patients in each group. Group I received 2µg/kg of clonidine in 100ml normal saline 30 min before surgery and Group II received 100ml normal saline. H.R., non-invasive B.P (N.I.B.P., oxygen saturation in arterial blood (SpO2 were recorded as base line, after induction, after intubation, then at 15 min internal intraoperatively and finally after extubation. H. R. and B. P. were assessed after 30 min, 2hr and 6hr postoperatively. Any complication, side effect and adverse effect upto 24 hrs postoperatively were noted. RESULTS AND CONCLUSION: In Group I, compared to Group II, there was significant decrease in B.P. and H.R. during intubation, intraoperatively, extubation and post operatively and the concentration of isoflurane used was also reduced. Blood loss and incidence of shivering was less and also tube tolerance ability was better when tube was left in situ after surgery Clonidine, 2µg/kg IV in 100ml normal saline, 30min before is safe and effective in preventing the hemodynamic surgical stress response as well as intubation, extubation stress response.

    In this study we investigated and compared the predictive values of different airway assessments tests including thyromental height measurement test, which has been recently suggested, in difficult laryngoscopy (Cormack and Lehane [C-L] scores 3 and 4). In addition, we compared the effectiveness of methods and C-L scores, by IDS, in terms of predicting difficult intubation. Prospective, blinded study. Maltepe University. Four hundred fifty-one patients selected randomly who underwent general anesthesia. In this study we compared predictive value of thyromental height measurement test (TMH), which has been recently suggested, modified Mallampati test (MMT), upper lip bite test (ULBT), and thyromental distance measurement test (TMD) in difficult laryngoscopy. Final C-L scores were compared with intubation difficulty scale (IDS) in terms of predicting difficult intubation. Patient's American Society of Anesthesiology score, age and weight were recorded. TMH, TMD, MMT, ULBT, IDS and C-L scores were measured and determined. The optimal cut-off point for TMH for predicting difficult laryngoscopy was 43.5 mm and for TMD was 82.06 mm. Use of TMH <43.5 with MMT has the highest sensitivity for predicting difficult intubation (78.38) with 75.36% specificity and 97.50% negative predictive value. TMH showed sensitivity of 91.89% and specificity 52.17% at 50 mm cut-off value. In the comparison of the area under the receiver operating characteristic curve values, none of the tests came forth individually or in combination with MMT test. The present study demonstrates the practicality of TMH as a digitalized test however the clinical benefits of TMH in daily medical practice are drawn into question. The additional variable of race may have had some bearing on this and further studies, larger in patient sample size, may need to use different methodology concerning age-, sex-, and race-dependent variables in evaluating these tests.

    The broader purpose of this study was to examine the temporal effects of high-intensity exercise on learning, short-term and long-term retrospective memory and prospective memory. Among a sample of 88 young adult participants, 22 were randomized into one of four different groups: exercise before learning, control group, exercise during learning, and exercise after learning. The retrospective assessments (learning, short-term and long-term memory) were assessed using the Rey Auditory Verbal Learning Test. Long-term memory including a 20-min and 24-hr follow-up assessment. Prospective memory was assessed using a time-based procedure by having participants contact (via phone) the researchers at a follow-up time period. The exercise stimulus included a 15-min bout of progressive maximal exertion treadmill exercise. High-intensity exercise prior to memory encoding (vs. exercise during memory encoding or consolidation) was effective in enhancing long-term memory (for both 20-min and 24-h follow-up assessments). We did not observe a differential temporal effect of high-intensity exercise on short-term memory (immediate post-memory encoding), learning or prospective memory. The timing of high-intensity exercise may play an important role in facilitating long-term memory. © 2017 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    The primary objective of this study was to determine the association between the size of the void established by using two different implant configurations and the amount of buccal/palatal bone loss that occurred during 16 weeks of healing following their installation into extraction sockets. The clinical trial was designed as a prospective, randomized-controlled parallel-group multicenter study. Adults in need of one or more implants replacing teeth to be removed in the maxilla within the region 15-25 were recruited. Following tooth extraction, the site was randomly allocated to receive either a cylindrical (group A) or a tapered implant (group B). After implant installation, a series of measurements were made to determine the dimension of the ridge and the void between the implant and the extraction socket. These measurements were repeated at the re-entry procedure after 16 weeks. The study demonstrated that the removal of single teeth and the immediate placement of an implant resulted in marked alterations of the dimension of the buccal ridge (43% and 30%) and the horizontal (80-63%) as well as the vertical (69-65%) gap between the implant and the bone walls. Although the dimensional changes were not significantly different between the two-implant configurations, both the horizontal and the vertical gap changes were greater in group A than in group B. Implant placement into extraction sockets will result in significant bone reduction of the alveolar ridge.

    Postoperative sore throat (POST), although a minor complication, remains a source of postoperative morbidity. We compared the efficacy of dispersible aspirin gargle to benzydamine hydrochloride (a topical nonsteroidal anti inflammatory drug) gargles for prevention of POST. We enrolled 60 consecutive female patients, 16-60 yr of age, ASA physical status I or II, undergoing elective modified radical mastectomy under general anesthesia in this prospective, randomized, placebo-controlled, single-blind study. Patients were randomly divided into 3 groups of 20 subjects each: Group 1 (C) mineral water; Group 2 (AS) tab aspirin 350 mg; and Group 3 (BH) 15 mL of benzydamine hydrochloride (0.15%). All the medications were made into 30 mL of solution. Patients were asked to gargle this mixture for 30 s, 5 min before induction of anesthesia. Grading of POST was done at 0, 2, 4, and 24 h postoperatively on a 4-point scale (0-3). Aspirin gargles reduced the incidence of POST for 4 h whereas benzydamine hydrochloride gargles reduced POST for 24 h. POST was more severe in the control group at 0 and 2 h (P benzydamine hydrochloride gargles significantly reduced the incidence and severity of POST (P < 0.05).

    Hypoxia is a major factor in delayed wound healing. The aim of this prospective, randomized, clinical trial was to compare outcomes of treatment in persons with chronic diabetic foot ulcers (DFUs) randomly assigned to transdermal continuous oxygen therapy (TCOT) for 4 weeks as an adjunct to standard care (debridement, offloading, and moisture). Nine patients (age 58.6±7.1, range 38-73 years) received TCOT (treatment group) and eight patients (age 59.9±12.6, range 35-76 years) received standard care alone (control group). Most patients (12) were male, and all had a Wagner I or II foot ulcer for an average of 14 (control group) or 20 months (treatment group). Weekly wound measurements and wound tissue biopsies were obtained and wound fluid collected. Levels of pro-inflammatory cytokines and proteases in wound fluid samples were analyzed using Luminex-based multiplex assays. Tissue-resident macrophages were quantified by immunohistochemistry. At week 4, average wound size reduction was 87% (range 55.7% to 100%) in the treatment group compared to 46% (15% to 99%) in the control group (P <0.05). Changes in cytokine levels (IL-6, IL-8) and proteinases (MMP-1,-2,-9, TIMP-1) at weeks 2 to 4 in wound fluid correlated with clinical findings. CD68+ macrophage counts showed statistically significant reduction in response to TCOT compared to the control group (P <0.01). The results of this study show that TCOT may facilitate healing of DFUs by reversing the inflammatory process through reduction in pro-inflammatory cytokines and tissue-degrading proteases. Additional research to elucidate the effects of this treatment on complete healing and increase understanding about the role of wound fluid analysis is needed.

    The present study was performed to determine whether thyroidectomy patients undergoing general anesthesia provided with a laryngeal mask airway (LMA) have a lower risk of voice-related complications and laryngopharyngeal symptoms than those undergoing endotracheal intubation (ETI). In a prospective, double-blinded, randomized clinical trial, we studied 64 patients undergoing elective thyroid lobectomy between July 2013 and February 2014. Acoustic analyses were performed preoperatively and at 48 h and 2 weeks postoperatively. The voice handicap index (VHI), M.D. Anderson dysphagia index (MDADI), and laryngopharyngeal symptom score (LPS) were determined preoperatively and at 24 h, 48 h, 1 week, and 2 weeks post-thyroidectomy. In acoustic analysis, jitter, shimmer and noise-to-harmonic ratio showed significantly better results in the LMA group than the ETI group 48 h after surgery, but there was no difference at 2 weeks. The incidence of postoperative lower-pitched voice in the LMA group was also significantly lower than that in the ETI group. In the LMA group, the VHI, MDADI, and LPS were better compared to those in the ETI group at 24 h postoperatively, and improved to the preoperative state within 1 week. However, those in the ETI group remained poorer than the preoperative values 1 week after surgery. Use of the LMA in general anesthesia for thyroid surgery has advantages over the ETI in decreasing patients' subjective and objective voice symptoms, reducing the duration of symptoms, and relieving the laryngopharyngeal symptoms.

    Full Text Available The primary objective of this pilot clinical trial was to evaluate the effects of UP165 (derived from Zea mays L., commonly known as corn over time. The secondary objective was the comparison for outcomes versus S-adenosyl-methionine (SAM-e. Subjects with mild depression or anxiety were given the Beck Depression Inventory second edition (BDI-II, the Beck Anxiety Inventory (BAI, and the Schwartz Outcome Scale (SOS-10. Forty-two subjects (21–65 years old were randomized to eight-weeks of supplementation with UP165 or SAM-e with questionnaires being administered at randomization, week four and eight. Those receiving UP165 achieved significant reduction from baseline at weeks four and eight, respectively for the BDI-II, as well as a trend for reduction in BAI at week four and significance at week eight. There was a trend for improvement on the SOS at week four and significance at week eight. SAM-e demonstrated a trend for improvement on the BDI-II by week eight over the UP165 with no differences between the two for the BAI or the SOS. Overall, this study indicates that there may be benefit to UP165 for mood enhancement in those with mild depression or anxiety. Randomized placebo comparator trials appear warranted.

    This randomized, open-label study evaluated the additional benefits of the synbiotic Prodefen® in the clinical management of acute diarrhea of suspected viral origin in children between 6 months and 12 years of age. Study outcomes included the duration of diarrhea, the recovery from diarrhea, and the tolerability and acceptance of the treatment. The proportion of patients without diarrhea over the study period was greater in the synbiotic group than in the control group at all study time points, showing a statistically significant difference on the fifth day (95% vs 79%, p diarrhea (median and interquartile range) was reduced by 1 day in the synbiotic-treated patients (3 [2-5] vs 4 [3-5], p = 0.377). The tolerability of the treatment regimen, as evaluated by the parents, was significantly better in those receiving the synbiotic than in the control group. Overall, 96% of the parents of children receiving the synbiotic reported being satisfied to very satisfied with the treatment regimen. The results of this study indicate that the addition of the synbiotic Prodefen® is a well-tolerated and well-accepted approach that provides an additional benefit to the standard supportive therapy in the management of acute viral diarrhea in children.

    Melatonin has been suggested as a new natural pain killer in inflammatory pain and during surgical procedures. We designed this randomized double-blind controlled study to evaluate the analgesic efficacy and also optimal preemptive dose of melatonin in patients undergoing cesarean section under spinal anesthesia . One hundred twenty patients scheduled for cesarean section under spinal anesthesia were randomly allocated to one of three groups of 40 each to receive melatonin 3 milligram (mg) (group M3), melatonin 6 mg (group M6) or placebo (group P) sublingually 20 min before the spinal anesthesia. The time to first analgesic request, analgesic requirement in the first 24 h after surgery, hemodynamic variables, anxiety scores nd the incidence of adverse events were recorded. The duration of anesthesia and analgesia didn’t show significant differences between three groups. Total analgesic request during 24 h after surgery was different among the three groups (P = 0.035). The incidence of headache in group M6 was significantly higher than others (P<0.001). However, after adjusting headache between groups of the study, we were unable to show the significant difference in the total analgesic request during 24 h after surgery among the three groups (p = 0.058). Although premedication of patients with 3 mg sublingual melatonin prolonged time to first analgesic request after cesarean delivery compared to placebo group, the difference was not statistically significant. Meanwhile increasing dose of melatonin to 6 mg failed to enhance analgesia and also increase the incidence of headache in patients undergoing cesarean section under spinal anesthesia.

    Perioperative monitoring systems produce a large amount of uninterpreted data, use threshold alarms prone to artifacts, and rely on the clinician to continuously visually track changes in physiological data. To address these deficiencies, we developed an expert system that provides real-time clinical decisions for the identification of critical events. We evaluated the efficacy of the expert system for enhancing critical event detection in a simulated environment. We hypothesized that anesthesiologists would identify critical ventilatory events more rapidly and accurately with the expert system. We used a high-fidelity human patient simulator to simulate an operating room environment. Participants managed 4 scenarios (anesthetic vapor overdose, tension pneumothorax, anaphylaxis, and endotracheal tube cuff leak) in random order. In 2 of their 4 scenarios, participants were randomly assigned to the expert system, which provided trend-based alerts and potential differential diagnoses. Time to detection and time to treatment were measured. Workload questionnaires and structured debriefings were completed after each scenario, and a usability questionnaire at the conclusion of the session. Data were analyzed using a mixed-effects linear regression model; Fisher exact test was used for workload scores. Twenty anesthesiology trainees and 15 staff anesthesiologists with a combined median (range) of 36 (29-66) years of age and 6 (1-38) years of anesthesia experience participated. For the endotracheal tube cuff leak, the expert system caused mean reductions of 128 (99% confidence interval [CI], 54-202) seconds in time to detection and 140 (99% CI, 79-200) seconds in time to treatment. In the other 3 scenarios, a best-case decrease of 97 seconds (lower 99% CI) in time to diagnosis for anaphylaxis and a worst-case increase of 63 seconds (upper 99% CI) in time to treatment for anesthetic vapor overdose were found. Participants were highly satisfied with the expert system (median

    The initial results of a prospective evaluation of myopic keratomileusis are reported. The procedure was attempted on 42 eyes, with an average follow-up of 10 months. The average reductions of myopia were 7.05 D and 11.59 D when measured by keratometry and refraction, respectively. Regular astigmatism increased by 0.50 D on keratometry, but there was no change in the refractive cylinder. The majority of patients had some irregular astigmatism on corneoscopy. The average percent correction, based on refraction, was 94.1 +/- 24%, and the correlation coefficient was 0.43. Visual rehabilitation was rapid. No patient followed for 1 year or more had a decrease in the best-corrected acuity, and 63% of this group had an average improvement of 1.5 lines with as much as five lines. The final refraction may take up to 6 months to stabilize. Complications consisted of epithelium and debris in the interface and focal necrosis of Bowman's membrane. The technique is difficult but may have application in the visual rehabilitation of the high myope.

    Atopic dermatitis (AD) is a frequent, chronic inflammatory disease influenced by local, immunological, genetic and environmental factors. Important symptoms of AD are dry skin, intense pruritus and impaired epidermal barrier function. The therapeutic management of AD is difficult and needs individualized concepts. Moisturizing creams and emollients are useful and important treatment adjuncts for the daily skin care of patients with dry and inflamed skin, e.g. AD. Glycerol is known to increase stratum corneum (SC) hydration, improve epidermal barrier function and decrease clinical signs of inflammation. However, no controlled study on the efficacy of glycerol on barrier function and SC hydration in AD has been published. In the present study, a topical 20% glycerol preparation was compared with its vehicle in patients with AD. The aim of the present study was to evaluate the effect of a single emollient ingredient in AD within the full frame of a phase III drug study. 24 patients with AD were treated for 4 weeks twice daily with a glycerol-based emollient in a randomized, double-blind study. Transepidermal water loss, skin capacitance, erythema and skin surface pH were assessed with biophysical, non-invasive instruments. The SCORAD and a local severity score were evaluated. After a wash-out period of 2 weeks, these parameters were assessed in order to quantify the sustained effect of this treatment. SC hydration was significantly improved, and epidermal barrier function was restored under treatment with glycerol-containing cream compared to the glycerol-free placebo. No significant differences were detectable for erythema values, SCORAD and local severity between the glycerol-containing cream and placebo. However, an improvement over time was detectable in the assessed parameters in both groups indicating the importance of emollient treatment in AD. Glycerol-based emollients have a positive influence on the skin of patients with AD. They enhance the SC hydration

    To evaluate the effect of exercise programs on pregnant women with pregnancy-related low back and pelvic pain. Low back and pelvic pain during pregnancy is a major health problem due to its frequent occurrence and such pain can limit pregnant women in many of their daily activities. A randomized trial with a control group (n = 48) and an intervention group (n = 48). Trial registration number NCT02189356. Department of Obstetrics and Gynecology, between December 2011-May 2012, an Education and Research Hospital in Turkey. Based on the intention-to-treat principle, all pregnant women were analysed according to the group they were assigned to, regardless of whether they received the intervention or not. Participants in the intervention group received health counselling and exercised regarding low back and pelvic pain for four weeks. The pregnant women in the control group received usual care, comprised of routine clinical practice for pregnancy-related low back and pelvic pain. According to Mann-Whitney U test analysis results, there was a statistically significant difference between the control and intervention groups' Visual Analogue Scale during relaxation scores and Visual Analogue Scale during activity scores at the end of the study. According to Mann-Whitney U test analysis results, the change in the mean Oswestry Disability Index score for the intervention group and the difference in the mean scores between the two groups was statistically significant. A four-week exercise program including individualized health counselling to relieve low back and pelvic pain improved the functional status in pregnant women. © 2015 John Wiley & Sons Ltd.

    Full Text Available Objectives. Overactive bladder (OAB is a chronic disease, but comparative trials of anticholinergics, which are commonly used for treatment of OAB, have generally been performed for up to 12 weeks only. There is no comparative study of a long-term intervention. Methods. We conducted a 52-week prospective randomized comparative study to evaluate the efficacy and tolerability of two anticholinergics. Results. Forty-one Japanese patients with untreated OAB were randomly assigned to imidafenacin and solifenacin groups. There was no difference in OABSS and KHQ scores between the two groups, but the severity and incidence of adverse events caused by the anticholinergics showed increased differences between the groups with time. The severity of dry mouth and the incidence of constipation were significantly lower in the imidafenacin group (=0.0092 and =0.0013, resp.. Conclusions. This study is the first long-term trial to show differences in the properties of anticholinergics that were not detected in short-term studies. Since OAB is a chronic disease, we conclude that imidafenacin is preferable to solifenacin from a perspective of safety.

    High cost of imported pacemakers is a main obstacle for Chinese patients suffering from bradyarrhythmia, and a domestically developed pacemaker will help lower the burden. This study aimed to evaluate the safety and efficacy of Qinming8631 DR (Qinming Medical, Baoji, China), the first domestically developed dual-chamber pacemaker of China, compared with a commercially available pacemaker Talos DR (Biotronik, Berlin, Germany) in Chinese patients. A prospective randomized trial was conducted at 14 centers in China. Participants were randomized into trial (Qinming8631 DR) and control (Talos DR) groups. Parameters of the pacing systems were collected immediately after device implantation and during follow-ups. The effective pacing rate at 6-month follow-up was recorded as the primary end point. Electrical properties, magnet response, single- and double-pole polarity conversion, rate response function, and adverse events of the pacing system were analyzed. The Cochran-Mantel-Haenszel Chi-square test, paired t-test, and Wilcoxon signed-rank test were used for measuring primary qualitative outcomes and comparing normally and abnormally distributed measurement data. A total of 225 patients with a diagnosis of bradyarrhythmia and eligible for this study were randomly enrolled into the trial (n = 113) and control (n = 112) groups. They underwent successful pacemaker implantation with acceptable postoperative pacing threshold and sensitivity. Effective pacing rates of trial and control groups were comparable both in the full analysis set and the per protocol set (81.4% vs. 79.5%, P = 0.712 and 95.4% vs. 89.5%, P = 0.143, respectively). In both data sets, noninferiority of the trial group was above the predefined noninferiority limit(-9.5%). This study established the noninferiority of Qinming8631 DR to Talos DR. The safety and efficacy of Qinming8631 DR pacemaker were comparable to those of Talos DR in treating patients with cardiac bradyarrhythmia.

    Full Text Available BACKGROUND: Mature oocytes are prerequisite for achieving the process of in vitro fertilization. Human chorionic gonadotropin (hCG is the standard trigger used for stimulating ovulation but is associated with ovarian hyperstimulation syndrome (OHSS. Gonadotropin-releasing hormone agonist trigger achieves oocyte maturation and lowers the incidence of OHSS, but it has limitations of higher pregnancy loss rate and miscarriage rates. Coadministration of both hormones is found to improve the pregnancy rates and the number of mature oocytes retrieved. We aimed to assess if the dual trigger is better than the conventional hCG in triggering oocyte maturation. METHODOLOGY: The study included 76 female patients aged 24–43 years who were randomly divided into two groups with 38 patients in each arm. The study included patients with antimullerian hormone (AMH 4 ng/ml and AFC/ovary >12 to avoid OHSS risk with hCG trigger. RESULTS: The study showed statistically insignificant differences between dual group versus hCG group in terms of the number of oocytes retrieved (10.0 ± 5.6 vs. 8.7 ± 5.0; P = 0.2816, the number of mature oocytes recovered (8.4 ± 5.0 vs. 7.2 ± 4.0; P = 0.2588, fertilization rate (5.9 ± 4.2 vs. 5.6 ± 3.3; P = 0.7390, and the number of usable embryos on day 3 (4.0 ± 3.0 vs. 4.0 ± 2.4; P = 0.8991. CONCLUSION: The dual trigger is equivalent to hCG in triggering oocyte maturation.

    Full Text Available Background: Perioperative pain is prevalent and poorly treated. Apart from that it makes the recovery from surgery unpleasent, pain often remains as a residual side effect of surgery, even though the tissue healing is complete. An essential observation is that tissue injury and the resulting nociceptor barrage initiates a cascade of events that can indelibly alter pain perception. Preemptive analgesia is the concept of initiating analgesic therapy before the onset of the noxious stimulus so as to prevent the nociceptor barrage and its consequences. However, anticipated clinical potency of preemptive analgesia, though has firmly grounded in the neurobiology of pain, has not been yet realized. As data accumulates, it has become clear that clinical studies emulating those from the laboratory and designed around a relatively narrow definition of preemptive analgesia have been largely unsupportive of its use. Nevertheless, preemptive analgesic interventions that recognize the intensity, duration, and somatotopic extent of major surgery can help reduce perioperative pain and its longer-term sequelae. surgeons spend a lot of time treating the pain of lower abdominal surgery. Methods: A total number of 48 consecutive patients who were going to undergo elective lower abdominal surgery. Were randomly assigned in two groups of 24 each. In one group the patients received an injection of 0.5 % bupivacaine in the planned skin for incision just before lower abdominal surgery, and in the other group, they received an equal amount of 0.5% bupivacaine after the surgery had been done. Pain was objectified by a numerical visual pain score, in the 24 hours following the lower abdominal surgery. Results: There were no differences in postoperative pain scores on the visual analog scale (VAS: In groups 1and 2, VAS at hour 4 were 6.37±1.13 versus 6.29±1.19; At hour 8 were 5.54 ± 1.17 versus 5.37±1.09; and at hour 12 were 4.5 ± 1.31 versus 4.45 ± 1

    Purpose The purpose of this study was to compare outcomes of subjects with open-angle glaucoma (OAG) not controlled on one medication who underwent either implantation of two iStent inject® trabecular micro-bypass devices or received medical therapy consisting of a fixed combination of latanoprost/timolol. Patients and methods Of 192 subjects who qualified for the study and were enrolled, 94 were randomized to surgery with implantation of two iStent inject® devices in the treated eye and 98 to receive medical therapy. Results At the month 12 visit, 94.7% of eyes (89/94) in the stent group reported an unmedicated intraocular pressure (IOP) reduction of ≥20% versus baseline unmedicated IOP, and 91.8% of eyes (88/98) in the medical therapy group reported an IOP reduction ≥20% versus baseline unmedicated IOP. A 17.5% between-group treatment difference in favor of the iStent inject group was statistically significant (P=0.02) at the ≥50% level of IOP reduction. An IOP ≤18 mmHg was reported in 92.6% of eyes (87/94) in the iStent inject group and 89.8% of eyes (88/98) in the medical therapy group. Mean (standard deviation) IOP decreases from screening of 8.1 (2.6) mmHg and 7.3 (2.2) mmHg were reported in the iStent inject and medical therapy groups, respectively. A high safety profile was also noted in this study in both the iStent inject and medical therapy groups, as measured by stable best corrected visual acuity, cup-to-disc ratio, and adverse events. Conclusion These data show that the use of iStent inject is at least as effective as two medications, with the clinical benefit of reducing medication burden and assuring continuous treatment with full compliance to implant therapy as well as having a highly favorable safety profile.

    Liver graft dysfunction can deteriorate to complete organ failure and increases perioperative morbidity and mortality after liver transplantation. Therapeutic strategies reducing the rate of graft dysfunction are of current clinical relevance. One approach is the systemic application of prostaglandins, which were demonstrated to be beneficial in reducing ischemia-reperfusion injury. Preliminary data indicate a positive effect of prostacyclin analogue iloprost on allograft viability after liver transplantation. The objective of the study is to evaluate the impact of iloprost in a multi-center trial. A prospective, double-blinded, randomized, placebo-controlled multicenter study in a total of 365 liver transplant recipients was designed to assess the effect of intravenous iloprost after liver transplantation. Primary endpoint will be the primary graft dysfunction characterized as presentation of one or more of the following criteria: ALAT or ASAT level>2000 IU/ml within the first 7 postoperative days, bilirubine  ≥ 10 mg/dl on postoperative day 7; INR ≥ 1.6 on postoperative day 7 or initial non-function. Secondary endpoints are parameters of post-transplant morbidity, like rates of infections, biliary complications, need of clotting factors or renal replacement therapy and the graft and patient survival. A well-established treatment concept to avoid graft dysfunction after liver transplantation does not exist at the moment. If the data of this research project confirm prior findings, iloprost would improve the general outcome after liver transplantation. German Clinical Trials Register: DRKS00003514.

    Full Text Available BACKGROUND : Ondansetron and granisetron are first generation 5 - hydroxytry - ptamine - 3 (5 - HT3 receptor antagonists widely used in the prophylaxis of postoperative nausea and vomiting (PONV. Orally Disintegrating Film (ODF formulations are novel and advanced oral drug delivery systems used in management of (PONV. We aimed to study the efficacy of ODF of Ondansetron in the prophylaxis of PONV and to compare it with intravenous Granisetron and placebo in patients undergoing Laparoscopic cholecystectomy . MATERIALS AND METHODS : In this prospective, randomized double - blind placebo - controlled study, 120 consented adult patients of ASA grade I and grade II, aged between 25 - 55 years of both genders, undergoing elective Laparoscopic cholecystectomy , w ere randomized into 3 groups of 40 patients each as Placebo, intravenous Granisetron 2mg and ODF of Ondansetron 8mg (ODF8 g roups. Study drugs were administered just before induction of Anaesthesia. Standardized anesthetic technique was used, and data was collected. Incidence of PONV was assessed and the number of patients suffering from nausea and vomiting at 0 - 6, 7 - 14, and overall 0 - 24 hours post - operatively was evaluated in all the groups and need for rescue anti - emetic noted. RESULTS : Data was analysed using one - way ANOVA test, Chi ‑ square test and Mann – Whitney test. The incidence and severity of nausea and vomiting at different time intervals in Group G and ODF Group was significantly lower when compared with Placebo Group ( p=0.000 . But there was no significant difference in between the ODF and in travenous groups. There was no significant difference in the incidence of side effects in between the three groups. CONCLUSION : orally disintegrating film of Ondansetron is a safe, simple and cost - effective, novel formulation , equally effective to intraven ous Granisetron in preventing PONV in patients undergoing laparoscopic cholecystectomy.

    Perineal reeducation of stress urinary incontinence is beneficial in 80% of cases. However, patients have to perform self-retraining exercises of the perineal muscles at home, in order to maintain the benefit of the physiotherapy. The aim of this study is to assess the benefit of GYNEFFIK(®), a perineal electro-stimulator, during this home-care phase. Women with stress urinary incontinence (UI) or with mixed UI (composed predominantly of stress UI) that responded to physiotherapy were included in this study in two parallel groups. The groups followed a self-reeducation program, with or without GYNEFFIK(®) electro-stimulation sessions. The comparison of the two groups was based on the rate of women for whom the benefit of the initial perineal reeducation was maintained (defined as non-worsening ICIQ and Ditrovie scales' score). According to the protocol, an interim analysis was performed on 95 patients (i.e. almost half of the expected sample size) who had had at least one evaluation under treatment, among which 44 patients had finished the study. The therapeutic benefit of the initial perineal reeducation was maintained in 87.8% of the GYNEFFIK(®) patient group, while it was maintained in 52.2% (P=0.0001) in the usual care group (i.e. who did not use electro-stimulation). Likewise, patient had a more favorable subjective impression when using GYNEFFIK(®) (83.7% versus 60.0% in the usual care group) as they felt that they improved during the study. In the GYNEFFIK(®) group, no increase in symptoms was reported, whereas almost one out of five patients in the usual care group felt that their condition had worsened. Copyright © 2014.

    Previous trials (Metoprolol CR/XL Randomised Intervention Trial in Congestive Heart Failure [MERIT-HF], Cardiac Insufficiency Bisoprolol Study [CIBIS] II) have demonstrated a mortality benefit of beta-adrenergic blockade in patients with mild to moderate heart failure. The recent Carvedilol Prospective Randomized Cumulative Survival (COPERNICUS) trial has extended these results to a more advanced patient population. This trial did not, however, include patients who could not reach compensation, patients with far advanced heart failure symptoms, or a significant number of black patients. Future studies of beta-blockade may focus on these patients or patients with asymptomatic left ventricular dysfunction.

    Three different techniques of anterior cruciate ligament (ACL) reconstruction--conventional (transtibial) single bundle (CSB), anatomic single bundle (ASB), and anatomic double bundle (ADB)--have been described. To determine if double-bundle reconstruction is needed to restore rotational stability or if anatomic placement of a single bundle can yield similar results. Randomized controlled trial; Level of evidence, 1. From December 2005 to December 2007, 320 patients were prospectively randomized into 3 groups: ADB, ASB, and CSB reconstruction. The average follow-up was 51.15 months (range, 39-63 months). At the final follow-up, 281 patients were available. In all groups, hamstring tendons were used with suspensory fixation on the femoral side and bioabsorbable interference screw fixation on the tibial side. The outcomes were evaluated by an independent blinded observer using the Lysholm score and subjective International Knee Documentation Committee (IKDC) form. The KT-1000 arthrometer was used to evaluate anteroposterior stability, and the pivot-shift test was used to determine rotational stability. Anatomic single-bundle reconstruction resulted in better anteroposterior and rotational stability than CSB reconstruction (average side-to-side difference for anterior tibial translation was 1.6 mm in the ASB group vs 2.0 mm in the CSB group; P = .002). Negative pivot shift was 66.7% vs 41.7% (P = .003). In other parameters, the differences between groups were not statistically significant. The results of the ADB group were also superior to the ASB group for anteroposterior and rotational stability (average side-to-side difference for anterior tibial translation was 1.2 mm in the ADB group vs 1.6 mm in the ASB group; P = .002). Negative pivot shift was 93.1% vs 66.7%, respectively (P ADB groups, respectively. The difference was significant only when we compared ADB and CSB (P = .025). Subjective IKDC scores were 90.2, 90.6, and 92.1 in the CSB, ASB, and ADB groups

    The e-learning education is a promising method, but there are few prospective randomized publications in oncology. The purpose of this study was to assess the level of retention of information in oncology from undergraduate students of physiotherapy. A prospective, controlled, randomized, crossover study, 72 undergraduate students of physiotherapy, from the second to fourth years, were randomized to perform a course of physiotherapy in oncology (PHO) using traditional classroom or e-learning. Students were offered the same content of the subject. The teacher in the traditional classroom model and the e-learning students used the Articulate® software. The course tackled the main issues related to PHO, and it was divided into six modules, 18 lessons, evaluated by 126 questions. A diagnosis evaluation was performed previous to the course and after every module. The sample consisted of 67 students, allocated in groups A (n = 35) and B (n = 32), and the distribution was homogeneous between the groups. Evaluating the correct answers, we observed a limited score in the pre-test (average grade 44.6 %), which has significant (p e-learning, a fact that encourages the use of e-learning in oncology.

A total of 96 children (aged 6 to 24 months) with temperature of more than 40 degrees C, no identifiable source of infection, and a leukocyte count greater than or equal to 15,000/microL and/or sedimentation rate greater than or equal to 30 were enrolled. The following tests were performed on all children: blood culture, chest roentgenogram, urinalysis, and urine culture. A lumbar puncture was performed if a child was 12 months or less. Patients were randomized to receive either no antibiotic therapy or Bicillin C-R, 50,000 U/kg intramuscularly, followed by penicillin V, 100 mg/kg/d, orally four times a day for three days. Patients were examined at 24 and 72 hours. Fifty patients were treated expectantly and 46 received no antimicrobial therapy. Ten of the 96 patients were bacteremic (nine had Streptococcus pneumoniae, one had Haemophilus influenzae). Four of the five children treated for bacteremia showed improvement at the first follow-up visit (afebrile and no obvious focus of infection). The five untreated patients showed no improvement; four patients developed focal infections (two had meningitis, two had otitis media) (P less than or equal to .05, Fisher exact test). No complications of expectant therapy were detected. Thus, expectant antibiotic therapy for children who have no obvious source of infection and who meet these criteria associated with occult bacteremia is warranted.

    After transposition into the urinary tract, intestinal segments continue to produce mucus. We determine the effectiveness of muco-regulatory drugs, including N-acetylcysteine, aspirin and ranitidine, in reducing mucus secretion and urine viscosity in patients with transposed segments. Our trial was a prospective randomized, double-blind placebo controlled crossover study involving 12 patients who underwent ileal conduit and 31 who underwent bladder reconstruction. Each treatment lasted 3 weeks with a 2-week washout. Pretreatment and posttreatment 24-hour urine samples were analyzed for mucin and viscosity after papain digestion, sodium dodecyl sulfate-polyacrylamide gel electrophoresis and periodic acid-Schiff assay. A disease specific questionnaire and SF-36 quality of life survey were completed. According to the questionnaire, mucus production did not decrease with time in 67% of patients. Mucin comprised 3% of the total nondialyzable material in urine (65 mg./24-hour for ileal conduit and 60 mg./24-hour for bladder reconstruction). Analysis of questionnaires and laboratory results failed to demonstrate any benefit of taking muco-regulatory agents compared with placebo. The use of N-acetylcysteine, aspirin and ranitidine did not result in a reduction in mucin production, urine viscosity or improvement in quality of life.

    Full Text Available BACKGROUND: Insomnia is underappreciated public health issue. In recent years, insomnia treatment has advanced beyond the routine use of benzodiazepines. AIMS: To compare the efficacy and safety of low dose Doxepin with Zopiclone in patients with primary insomnia. SETTINGS AND DESIGN: A double blind, randomized parallel group, prospective study of low dose Doxepin (n=20 and Zopiclone (n=15 in patients with primary insomnia. METHODS & MATERIAL: Patients fulfilling the selection criteria were enrolled. Enrolled patients were randomized to 2 groups- of low dose Doxepin(3mg and Zopiclone (3.75mg. Patients were provided with sleep diaries to record sleep parameters, change in alertness and mood, sleepiness scale score and other adverse events were recorded. STATISTICAL ANALYSIS: Student ‘t’ test. RESULTS: Both the groups show significant reduction the time of wakening after sleep onset, with improvement in both total sleep time & sleep efficiency. Both the drugs were well tolerated and percentage change in mood and alertness was comparable. CONCLUSION: Low dose Doxepin was found to be as effective and safe as Zopiclone in patients of primary insomnia

    Full Text Available Background and objectives: Acetylcholinesterase inhibitors may cause postoperative residual curarization when they are used for reversal of neuromuscular blockade. Sugammadex reverses neuromuscular blockade by chemical encapsulation and is not associated with the side effects that may occur with the use of anticholinesterase agents. Because of increased outpatient surgical procedures postoperative residual curarization and rapid postoperative recovery have a greater importance in the pediatric patient population. The aim of this study was to compare the efficacy of sugammadex and neostigmine on reversing neuromuscular blockade in pediatric patients undergoing outpatient surgical procedures. Methods: 80 patients, aged 2-12 years, scheduled for outpatient surgery were enrolled in this randomized prospective study. Neuromuscular blockade was achieved with 0.6 mgkg−1 rocuronium and monitorized with train-of-four. Group RN (n = 40 received 0.03 mgkg−1 neostigmine, Group RS (n = 40 received 2 mgkg−1 sugammadex for reversal of rocuronium. Extubation time (time from the reversal of neuromuscular blockade to extubation, train-of-four ratio during this time, time to reach train-of-four > 0.9, and probable complications were recorded. Results: There was no significant difference between the patients' characteristics. Extubation time and time to reach train-of-four > 0.9 were significantly higher in Group RN (p = 0.001, p = 0.002. Train-of-four at the time of neostigmine/sugammadex injection in Group RN were significantly higher than in the RS group (p = 0.020. Extubation train-of-four ratio was significantly lower in Group RN (p = 0.002. Conclusion: Sugammadex provides safer extubation with a shorter recovery time than neostigmine in pediatric patients undergoing outpatient surgical procedures.

    A prospective randomized controlled study was designed to evaluate differences in efficacy and complication rate between the two most commonly used sclerosing agents, sodium tetradecyl sulfate (STD) and polidocanol. Of 52 patients with esophageal variceal bleeding, 26 were randomized to receive sclerotherapy with 1.5% STD and 26 to receive 1% polidocanol at weekly intervals. Eradication of varices was achieved in 88% patients each of the STD and polidocanol group. There was no significant difference between patients injected with STD and polidocanol with regard to re-bleeding (27% vs. 15%) and mortality (11.5% in both). The use of STD, in contrast to polidocanol, was associated with a higher incidence of complications in terms of severe retrosternal pain (27% vs. 4%), deep ulceration (53% vs. 23%), dysphagia (88% vs. 46%), and stricture formation (27% vs. 8%). It was concluded that these two agents were similar in efficacy. However, polidocanol was superior due to a lower incidence of complications.

    Resting heart rate variability (HRV) is a measure of the modulation of autonomic nervous system (ANS) at rest. Increased HRV achieved by the exercise is good for the cardiovascular health. However, prospective studies with comparison of the effects of yogic exercises and those of other endurance exercises like walking, running, and swimming on resting HRV are conspicuous by their absence. Study was designed to assess and compare the effects of yogic training and swimming on resting HRV in normal healthy young volunteers. Study was conducted in Department of Physiology in a medical college. Study design was prospective randomized comparative trial. One hundred sedentary volunteers were randomly ascribed to either yoga or swimming group. Baseline recordings of digital electrocardiogram were done for all the subjects in cohorts of 10. After yoga training and swimming for 12 weeks, evaluation for resting HRV was done again. Percentage change for each parameter with yoga and swimming was compared using unpaired t-test for data with normal distribution and using Mann-Whitney U test for data without normal distribution. Most of the HRV parameters improved statistically significantly by both modalities of exercise. However, some of the HRV parameters showed statistically better improvement with yoga as compared to swimming. Practicing yoga seems to be the mode of exercise with better improvement in autonomic functions as suggested by resting HRV.

    Chronic obstructive pulmonary disease (COPD) is a common disease that leads to huge economic and social burden. Efficient and effective management of stable COPD is essential to improve quality of life and reduce medical expenditure. The Internet of Things (IoT), a recent breakthrough in communication technology, seems promising in improving health care delivery, but its potential strengths in COPD management remain poorly understood. We have developed a mobile phone-based IoT (mIoT) platform and initiated a randomized, multicenter, controlled trial entitled the 'MIOTIC study' to investigate the influence of mIoT among stable COPD patients. In the MIOTIC study, at least 600 patients with stable GOLD group C or D COPD and with a history of at least two moderate-to-severe exacerbations within the previous year will be randomly allocated to the control group, which receives routine follow-up, or the intervention group, which receives mIoT management. Endpoints of the study include (1) frequency and severity of acute exacerbation; (2) symptomatic evaluation; (3) pre- and post-bronchodilator forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) measurement; (4) exercise capacity; and (5) direct medical cost per year. Results from this study should provide direct evidence for the suitability of mIoT in stable COPD patient management.

    In spite of its widespread use after orthopaedic procedures, the literature evaluating the clinical efficacy of cryotherapy is controversial. The purpose of this prospective randomized trial was to compare two different temperatures for administering cryotherapy after total knee arthroplasty with regards to short-term postoperative outcomes. Sixty-four subjects were assigned either the 45 degrees F group or the 75 degrees F group. Subjects in the 45 degrees group were as likely to report a lower pain score at the time of follow-up compared to the 75 degrees group. Our results demonstrate no additional analgesic effect associated with the lower temperature of cryotherapy. Postoperative narcotic consumption, postoperative drainage, self-reported knee function, and range of motion were not affected by the different cryotherapy temperatures. No adverse effects were reported with the cryotherapy treatment.

    Full Text Available To evaluate the current evidence for effectiveness of acupuncture for posttraumatic stress disorder (PTSD in the form of a systematic review, a systematic literature search was conducted in 23 electronic databases. Grey literature was also searched. The key search terms were “acupuncture” and “PTSD.” No language restrictions were imposed. We included all randomized or prospective clinical trials that evaluated acupuncture and its variants against a waitlist, sham acupuncture, conventional therapy control for PTSD, or without control. Four randomized controlled trials (RCTs and 2 uncontrolled clinical trials (UCTs out of 136 articles in total were systematically reviewed. One high-quality RCT reported that acupuncture was superior to waitlist control and therapeutic effects of acupuncture and cognitive-behavioral therapy (CBT were similar based on the effect sizes. One RCT showed no statistical difference between acupuncture and selective serotonin reuptake inhibitors (SSRIs. One RCT reported a favorable effect of acupoint stimulation plus CBT against CBT alone. A meta-analysis of acupuncture plus moxibustion versus SSRI favored acupuncture plus moxibustion in three outcomes. This systematic review and meta-analysis suggest that the evidence of effectiveness of acupuncture for PTSD is encouraging but not cogent. Further qualified trials are needed to confirm whether acupuncture is effective for PTSD.

    Dual PPARα/γ can improve both metabolic effects and minimized the side effects caused by either PPARα or PPARγ agonist. The PRESS V study was aimed to evaluate the safety, tolerability, and efficacy of saroglitazar 2 mg and 4 mg capsules (Lipaglyn™; Zydus Code: ZYH1) as compared to high dose pioglitazone in patients with diabetic dyslipidemia. In this 26-week double-blind, parallel arm, phase 3 study patients with hypertriglyceridemia with type 2 diabetes mellitus (BMI > 23 kg/m(2); hypertriglyceridemia: TG > 200 to 400 mg/dL; glycosylated hemoglobin [HbA1c] >7 to 9%) were enrolled from 14 sites in India. After 2 weeks of lifestyle modification, 122 patients were randomized double-blind to 24-week treatment with the study drugs (saroglitazar 2 mg or 4 mg or pioglitazone 45 mg once daily) in a 1:1:1 ratio. The primary end point was change in plasma triglyceride level at week 24. The secondary end points were change in lipid profile and fasting plasma glucose at week 24. Patients who received study medication and had undergone at least 1 postbaseline efficacy evaluation were included in the efficacy analysis. All randomized patients who received at least a single dose were included for safety evaluation. The efficacy analysis included 109 patients (n = 37 in saroglitazar 2 mg; n = 39 in saroglitazar 4 mg; n = 33 in pioglitazone). Saroglitazar 2 mg and 4 mg significantly reduced (P pioglitazone -15.5% (absolute change ± SD: -33.3 ± 162.41 mg/dL) at week 24. Saroglitazar 4 mg treatment also demonstrated marked decrease in low-density lipoprotein (5%), very-low-density lipoprotein (45.5%), total cholesterol (7.7%), and apolipoprotein-B (10.9%). Saroglitazar treatment was generally safe and well tolerated. No serious adverse events were reported in saroglitazar treatment arm and no persistent change in laboratory parameters. Saroglitazar appeared to be an effective and safe therapeutic option for improving hypertriglyceridemia in patients with type 2 diabetes

    Background This randomized double blind placebo controlled dual site clinical trial compared a probiotic dietary supplement to placebo regarding effects on gastrointestinal symptoms in adults with post-prandial intestinal gas-related symptoms (abdominal pain, distention, flatulence) but no gastrointestinal (GI) diagnoses to explain the symptoms. Methods Sixty-one adults were enrolled (age 36.5 ± 12.6 years; height 165.1 ± 9.2 cm; weight 75.4 ± 17.3 kg) and randomized to either Digestive Advantage™ Gas Defense Formula - (GanedenBC30 Bacillus coagulans GBI-30, 6086): n = 30; or Placebo: n = 31. Study subjects were evaluated every two weeks over a four-week period using validated questionnaires and standard biochemical safety testing. Outcome criteria of interest included change from baseline in Gastrointestinal Symptom Rating Scale (GSRS) abdominal pain, abdominal distention, flatus, and the Severity of Dyspepsia Assessment (SODA) bloating and gas subscores over four weeks of product use. Results Measured against the placebo, subjects in the probiotic group achieved significant improvements in GSRS abdominal pain subscore (p = 0.046) and the GSRS total score (p = 0.048), with a strong trend for improvement on the GSRS abdominal distension subscore (p = 0.061). A strong placebo effect was evident which could explain the lack of statistical significant differences between the groups for many of the efficacy variables. Conclusion In conclusion, the Bacillus coagulans-based product was effective in improving the quality of life and reducing gastrointestinal symptoms in adults with post prandial intestinal gas-related symptoms and no GI diagnoses.

    Background: Epidemiological studies have linked adult height with breast cancer risk in women. However, the magnitude of the association, particularly by subtypes of breast cancer, has not been established. Furthermore, the mechanisms of the association remain unclear. Methods: We performed a meta-analysis to investigate associations between height and breast cancer risk using data from 159 prospective cohorts totaling 5216302 women, including 113178 events. In a consortium with individual-level data from 46325 case patients and 42482 control subjects, we conducted a Mendelian randomization analysis using a genetic score that comprised 168 height-associated variants as an instrument. This association was further evaluated in a second consortium using summary statistics data from 16003 case patients and 41335 control subjects. Results: The pooled relative risk of breast cancer was 1.17 (95% confidence interval [CI] = 1.15 to 1.19) per 10cm increase in height in the meta-analysis of prospective studies. In Mendelian randomization analysis, the odds ratio of breast cancer per 10cm increase in genetically predicted height was 1.22 (95% CI = 1.13 to 1.32) in the first consortium and 1.21 (95% CI = 1.05 to 1.39) in the second consortium. The association was found in both premenopausal and postmenopausal women but restricted to hormone receptor–positive breast cancer. Analyses of height-associated variants identified eight new loci associated with breast cancer risk after adjusting for multiple comparisons, including three loci at 1q21.2, DNAJC27, and CCDC91 at genome-wide significance level P < 5×10–8. Conclusions: Our study provides strong evidence that adult height is a risk factor for breast cancer in women and certain genetic factors and biological pathways affecting adult height have an important role in the etiology of breast cancer.

    Full Text Available CONTEXT AND OBJECTIVES: In major orthopedic surgery of the lower limbs, continuous spinal anesthesia (CSA and combined spinal epidural anesthesia (CSE are safe and reliable anesthesia methods. In this prospective randomized clinical study, the blockading properties and side effects of CSA were compared with single interspace CSE, among patients scheduled for major hip or knee surgery. DESIGN AND SETTING: Prospective clinical study conducted at the Institute for Regional Anesthesia, Hospital de Base, São José do Rio Preto. METHODS: 240 patients scheduled for hip arthroplasty, knee arthroplasty or femoral fracture treatment were randomly assigned to receive either CSA or CSE. Blockades were performed in the lateral position at the L3-L4 interspace. Puncture success, technical difficulties, paresthesia, highest level of sensory and motor blockade, need for complementary doses of local anesthetic, degree of technical difficulties, cardiocirculatory changes and postdural puncture headache (PDPH were recorded. At the end of the surgery, the catheter was removed and cerebrospinal fluid leakage was evaluated. RESULTS: Seven patients were excluded (three CSA and four CSE. There was significantly lower incidence of paresthesia in the CSE group. The resultant sensory blockade level was significantly higher with CSE. Complete motor blockade occurred in 110 CSA patients and in 109 CSE patients. Arterial hypotension was observed significantly more often in the CSE group. PDPH was observed in two patients of each group. CONCLUSION: Our results suggest that both CSA and CSE provided good surgical conditions with low incidence of complications. The sensory blockade level and hemodynamic changes were lower with CSA.

    Quantum random-number generators (QRNGs) can offer a means to generate information-theoretically provable random numbers, in principle. In practice, unfortunately, the quantum randomness is inevitably mixed with classical randomness due to classical noises. To distill this quantum randomness, one needs to quantify the randomness of the source and apply a randomness extractor. Here, we propose a generic framework for evaluating quantum randomness of real-life QRNGs by min-entropy, and apply it...

    Sedative effects of single and repeated doses of 50 mg and 150 mg tolperisone hydrochloride (Mydocalm), a centrally active muscle-relaxing agent, were evaluated in a placebo-controlled double-blind clinical trial. A total of 72 healthy young adults balanced by sex were randomized to receive 50 mg or 150 mg tolperisone hydrochloride or placebo t.i.d. for a period of 8 days. Control examinations were performed in the mornings of days 1 and 8 before intake of the morning dose and at 1.5, 4 and 6 hours postdose. The psychomotoric test battery used in this trial revealed no sedative effects of tolperisone hydrochloride in the given doses at any control examination. Subjective mood ratings quantified by the Welzel Colored Scales were not impaired either. The lack of differences in sedative potentials of tolperisone hydrochloride and placebo was confirmed by tests on differences and by tests on equivalence using 95% CI. The present study substantiates clinical experience and previous clinical trials demonstrating that tolperisone hydrochloride, though being a centrally active muscle relaxant, does not cause any sedation and does not impair reaction times.

    1995-01-01

    We performed a prospective, randomized study to evaluate the use of injected lidocaine as an anesthetic for closed reduction of acute anterior shoulder dislocations. Thirty consecutive patients who presented at the emergency department with acute anterior shoulder dislocations were randomly placed in one of two groups. One group received an intraarticular injection of 20 ml of 1% lidocaine and the other group, intravenous injections of morphine sulfate and midazolam. The groups were compared regarding time of reduction maneuver, difficulty of reduction, subjective pain, complications, and total time spent in the emergency department. The lidocaine provided adequate anesthesia and secondary relief of muscle spasm in 15 of 15 (100%) patients. When compared with the intravenous sedation group, the lidocaine group showed no statistically significant difference in time for reduction maneuver, difficulty of reduction, or subjective pain. The lidocaine group had no complications and had a statistically significant shorter emergency department visit when compared with the intravenous sedation group (mean, 78 minutes versus 186 minutes; P = 0.004). Lidocaine provides excellent anesthesia for patients with uncomplicated anterior shoulder dislocations and can be very beneficial when sedation is contraindicated. Lidocaine injections also proved to be cost effective in our institution, reducing total costs by as much as 62%.

    Full Text Available Objectives The aim of this randomized, controlled, prospective clinical study was to evaluate patients' intraoperative discomfort during root canal preparations in which either multi-file rotary (Mtwo or single-file reciprocating (Reciproc systems were used. Materials and Methods Fifty-five adult patients, aged between 25 and 69 years old, with irreversible pulpitis or pulp necrosis participated in this study. Either the mesiobuccal or the distobuccal canals for maxillary molars and either the mesiobuccal or the mesiolingual canals for mandibular molars were randomly chosen to be instrumented with Mtwo multi-file rotary or Reciproc single-file reciprocating systems. Immediately after each canal instrumentation under anesthesia, patient discomfort was assessed using a 1 - 10 visual analog scale (VAS, ranging from ‘least possible discomfort’ (1 to ‘greatest possible discomfort’ (10. The Wilcoxon signed-rank test was used to determine significant differences at p< 0.05. Results Little intraoperative discomfort was found in all cases. No statistically significant differences in intraoperative discomfort between the 2 systems were found (p = 0.660. Conclusions Root canal preparation with multi-file rotary or single-file reciprocating systems had similar and minimal effects on patients' intraoperative discomfort.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the effects of platelet-rich plasma (PRP infiltration in patients with lateral epicondylitis of the elbow, through analysis of the Disabilities of the Arm, Shoulder and Hand (DASH and Patient-Rated Tennis Elbow Evaluation (PRTEE questionnaires. METHODS: Sixty patients with lateral epicondylitis of the elbow were prospectively randomized and evaluated after receiving infiltration of three milliliters of PRP, or 0.5% neocaine, or dexamethasone. For the scoring process, the patients were asked to fill out the DASH and PRTEE questionnaires on three occasions: on the day of infiltration and 90 and 180 days afterwards. RESULTS: Around 81.7% of the patients who underwent the treatment presented some improvement of the symptoms. The statistical tests showed that there was evidence that the cure rate was unrelated to the substance applied (p = 0.62. There was also intersection between the confidence intervals of each group, thus demonstrating that the proportions of patients whose symptoms improved were similar in all the groups. CONCLUSION: At a significance level of 5%, there was no evidence that one treatment was more effective than another, when assessed using the DASH and PRTEE questionnaires.

    Few studies have evaluated granulocyte colony-stimulating factor (G-CSF) priming in elderly patients with intensively treated acute myeloid leukemia (AML), and no data are available for genetically defined AML subgroups. We provide long-term results (median follow-up 7.6 years) of a randomized trial in which 183 patients (median age 67 years) received G-CSF prior to (G-CSF priming) or after two cycles of induction chemotherapy. CR rates with G-CSF priming and G-CSF post-chemotherapy were comparable (57 vs. 67 %, p = 0.153), with overall survival (OS) probabilities of 14 vs. 17 % at 10 years. Induction mortality was significantly higher with G-CSF priming (23 vs. 10 %, p = 0.015), primarily in normal karyotype (NK) AML. In this subgroup, a trend for better relapse-free survival (RFS) was observed with G-CSF priming (44 vs. 22 % at 10 years, p = 0.074) but did not translate into an OS benefit. G-CSF priming had no impact on AML with FLT3-ITD and NPM mutations and did not improve outcome in patients with adverse cytogenetics. In a landmark analysis, late consolidation with autologous stem cell transplantation or a second consolidation cycle significantly improved RFS compared with one consolidation cycle (21.0 vs. 12.8 months, p = 0.046). Future studies on G-CSF priming should be restricted to NK AML and used only in post-remission therapy.

    2005-05-01

    Full Text Available Abstract Background Drains are usually left after thyroid surgery to prevent formation of hematoma and seroma in the thyroid bed. This is done to reduce complications and hospital stay. Objective evaluation of the amount collected in the thyroid bed by ultrasonography (USG can help in assessing the role of drains. Methods A randomized prospective control study was conducted on 94 patients undergoing 102 thyroid surgeries, over a period of fifteen months. Patients included in the study were randomly allocated to drain and non-drain group on the basis of computer generated random number table. The surgeon was informed of the group just before the closure of the wound Postoperatively USG neck was done on first and seventh postoperative day by the same ultrasonologist each time. Any swelling, change in voice, tetany and tingling sensation were also recorded. The data was analyzed using two-sample t-test for calculating unequal variance. Results Both groups were evenly balanced according to age, sex, and size of tumor, type of procedure performed and histopathological diagnosis. There was no significant difference in collection of thyroid bed assessed by USG on D1 & D7 in the two groups (p = 0.313 but the hospital stay was significantly reduced in the non-drain group (p = 0.007. One patient in the drain group required needle aspiration for collection in thyroid bed. No patient in either group required re-operation for bleeding or haematoma. Conclusion Routine drainage of thyroid bed following thyroid surgery may not be necessary. Not draining the wound results in lesser morbidity and decreased hospital stay.

    Reirradiation is a potentially useful option for many patients with recurrent cancer. The purpose of this study was to review all recently published randomized trials in order to identify methodological strengths and weaknesses, comment on the results, clinical implications and open questions, and give advice for the planning of future trials. Systematic review of trials published between 2000 and 2015 (databases searched were PubMed, Scopus and Web of Science). We reviewed 9 trials, most of which addressed reirradiation of head and neck tumours. The median number of patients was 69. Trial design, primary endpoint and statistical hypotheses varied widely. The results contribute mainly to decision making for reirradiation of nasopharynx cancer and bone metastases. The trials with relatively long median follow-up confirm that serious toxicity remains a concern after high cumulative total doses. Multi-institutional collaboration is encouraged to complete sufficiently large trials. Despite a paucity of large randomized studies, reirradiation has been adopted in different clinical scenarios by many institutions. Typically, the patients have been assessed by multidisciplinary tumour boards and advanced technologies are used to create highly conformal dose distributions. (orig.)

    To evaluate acupuncture as treatment for glaucoma. Prospective double-masked randomized crossover study. setting: Clinical practice. One eye per patient with primary open-angle glaucoma and stable intraocular pressure (IOP). Patients were randomized to receive 1 acupuncture series (12 sessions with either eye-related [eye-points] or non-eye-related [non-eye-points] acupoints) and then crossed over to receive the other series. IOP, blood pressure (BP), heart rate (HR), best-corrected visual acuity (BCVA), visual field (VF), optic disc and peripapillary retinal nerve fiber layer (RNFL) measurements, compliance, and adverse reactions. Probability to detect 3 mm Hg IOP difference between series was 90%. Twenty-two patients volunteered and 11 (50.0%) completed the study; 8 (36.4%) did not complete treatment owing to changes of health, moving away, lack of transportation, or family crisis; and 3(13.6%) were withdrawn owing to needle sensitivity or IOP elevation (8 mm Hg) in the contralateral eye. After an acupuncture session, mean IOP increased slightly with both eye-points (from 12.9 ± 1.8 mm Hg to 13.6 ± 2.0 mm Hg, P = .019) and non-eye-points (from 13.0 ± 1.5 mm Hg to 13.5 ± 1.7 mm Hg, P = .073) series. HR, diurnal IOP, and BCVA showed no statistically significant changes after 12 sessions of either series. Systolic and diastolic BP were reduced after 12 sessions of non-eye-points series (P = .040, P = .002, respectively). Optic disc, RNFL, and VF showed no statistically significant changes. Acupuncture has no overall effect on diurnal IOP or BCVA but may temporally increase the IOP immediately after a treatment session. BP is lowered by acupuncture with non-eye-points, but not with eye-points. Compliance and adverse event rates were low. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Acute amniotic fluid infection has emerged as a possible cause of many heretofore unexplained preterm births. Our purpose was to determine the effect of ampicillin in the prolongation of pregnancies receiving tocolysis for preterm labor. A blinded, placebo-controlled, randomized trial was conducted to study ampicillin in women hospitalized for preterm labor between 24 and 37 weeks' gestation. A total of 60 patients with intact membranes and without chorioamnionitis who were receiving magnesium sulfate were screened. Thirty women with preterm labor received ampicillin, and 30 received placebos. The primary end point was prolongation of gestation. There was no difference in age of delivery (37.6±9.7 days vs 36.08±3.9 days, P=0.085 and no difference in retardation of delivery (4.7±3.1 vs 4.1±2.1, P=0.39. The mean degree of preterm delivery were 0.62±1.93 and 1.8±3.3 weeks in ampicillin and placebo groups, respectively (not significant, P>0.1. Conclusions: Ampicillin had no effect on interval to delivery or duration of pregnancy in women treated for preterm labor. So rotine clinical use of ampicillin during tocolysis should not be recommended.

    To evaluate, in a prospective randomized pilot study, the effectiveness and safety of tamsulosin, administered in patients with distal ureteric stones and who have already undergone an unsuccessful first cycle of medical expulsive therapy (MET). We evaluated the effectiveness and safety of tamsulosin, administered as a further therapy, in patients previously unsuccessfully treated with combined expulsive 10-day therapy (tamsulosin + deflazacort) for distal ureteric stones. Ninety-one patients were enrolled and randomized into two groups, each receiving a different therapy for 10 days. Group A (46 patients) received a further cycle of tamsulosin (0.4 mg daily), and group B (45) did not. Age, gender, stone size, time to expulsion, number of acute episodes of colic during treatment and analgesic consumption were recorded. Patients who were not stone-free after the study period had ureteroscopy. The results were compared statistically using Student's t-, chi-square test and Fisher's exact test. The groups were comparable in age, gender and stone size (5.93 mm for group A and 6.03 mm for group B). The expulsion rate was significantly higher in group A (80%) than in group B (49%) (P < 0.01), whilst there were no differences between the groups in the number of colic episodes and analgesic use. There were no reported side-effects of medical therapy. A second cycle of 10 days of MET with tamsulosin in nonresponders to a 10-day first cycle of MET with tamsulosin and deflazacort is safe and effective, and therefore should be considered as an option in the management of uncomplicated distal ureteric stones.

    To prospectively evaluate the impact of increasing levels of social media engagement on page visits and web-link clicks for content published in the Journal of the American College of Radiology. A three-arm prospective trial was designed using a control group, a basic Twitter intervention group (using only the Journal's @JACRJournal Twitter account), and an enhanced Twitter intervention group (using the personal Twitter accounts of editorial board members and trainees). Overall, 428 articles published between June 2013 and July 2015 were randomly assigned to the three groups. Article-specific tweets for both intervention arms were sent between September 14, 2015, and October 28, 2015. Primary end points included article-specific weekly and monthly page visits on the journal's Elsevier website (Amsterdam, Netherlands). For the two intervention groups, additional end points included 7-day and 30-day Twitter link clicks. Weekly page visits for the enhanced Twitter arm (mean 18.2; 95% confidence interval [CI] 15.6-20.7) were significantly higher when compared with the weekly page visits for the control arm (mean 7.6; 95% CI 1.7-13.6). However, there was no demonstrable increase in weekly page visits (mean 9.4; 95% CI 7.4-11.5) for the basic Twitter arm compared with the control arm. No intervention effects over control, regardless of Twitter arm assignment, were demonstrated for monthly page visits. The enhanced Twitter intervention resulted in a statistically significant increase in both 7-day and 30-day Twitter link clicks compared with the basic Twitter intervention group. An organized social media strategy, with focused social media activity from editorial board members, increased engagement with content published in a peer-reviewed radiology journal.

    The objective of this prospective, randomized clinical trial was to test the hypothesis that there is no difference in the frequency of feeding problems and necrotizing enterocolitis between a group of premature infants who received early enteral feedings while low umbilical artery catheters (LUACs) were in place, and a late group who were not fed until 24 hours after removal of LUACs. Twenty-nine premature infants (born at 28.5 +/- 3.0 SD weeks of gestational age) who were in stable condition received early enteral feedings at a median of 2 days while a LUAC was in place; 31 infants (born at 28.6 +/- 2.7 SD weeks of gestational age) received late enteral feedings at a median of 5 days of age, 24 hours after the removal of the LUAC. Feeding complications and interventions and nutritional characteristics were recorded prospectively. There were no differences in the baseline perinatal characteristics of the two groups. The incidence of gastric residua and the incidence of abdominal distention were the same in both groups. The early feeding group had significantly fewer percutaneous central venous catheters, evaluations for sepsis, and episodes of receiving nothing by mouth while a gastric suction tube was in place. Infants in the early group received parenteral alimentation-lipid emulsion infusions for a median of 13 days versus 30 days for the late-fed group (p = 0.0028 by Wilcoxon test). There were two cases of necrotizing enterocolitis in the early group versus four cases in the late group. Premature infants in stable condition who receive enteral feedings while LUACs are in place do not have an increased incidence of feeding problems compared with infants who do not receive enteral feedings until 24 hours after removal of LUACs.

    Postsurgical pain in adults following tonsillectomy with fibrin sealant or electrocoagulation was assessed by surface electromyography (sEMG), a dysphagia severity rating scale (DSRS), and a visual analog scale (VAS) pain For group 1 (n = 40), hemostasis was achieved by fibrin sealant spraying to the tonsillar fossae. For group 2 (n = 40), hemostasis was achieved by bipolar or needle point electrocautery. The timing of single swallowing and continuous drinking and the mean electrical activity of the masseter, infrahyoid, and submental-submandibular muscles were compared with a normative database during 30 days and with DSRS and VAS scores. Electrical activity of the masseter and infrahyoid muscles was significantly higher in both groups in comparison with the normative database (p sEMG, DSRS, and VAS assessment showed that tonsillectomy ended with sealant causes less pain than electrocoagulation (p sEMG records, whereas the VAS pain score was less informative. The combined sEMG and pain score data indicate that the electrocautery hemostatic technique is more painful and traumatic than the sealant technique. Surface electromyography of swallowing is a simple, reliable evaluation method for postsurgical odynophagia complaints and might be used as an objective tool for pain assessment.

With gained experience and new materials, laparoscopic repair of incisional hernia is now applied. This study was aimed to compare the results of incisional hernia repair with the open surgery or laparoscopic approach at the only centre in the region for laparoscopic incisional hernia repair. A total of 55 cases of incisional hernia at the General Surgery Clinic of SDU between November 2012 and 2014 were underwent laparoscopic ventral hernia repair (L-VHR and conventional incisional hernia repair (C-VHR. From the L-VHR group 6 cases and from the C-VHR 9 cases were excluded from the study, as they did not meet the inclusion criteria or did not wish to participate in the study. The two techniques were compared in respect of operative time, length of hospital stay, postoperative pain scores, complications and recurrence. A total of 40 cases of incisional hernia repair were evaluated. The mean follow-up period was found as 12.75±4.19 months. No difference was determined between the characteristics of the patients due to age, body mass index, American Society of Anesthesiologists (ASA score, comorbidities, hernia size, and follow-up. In the laparoscopic repair group, the postoperative pain scores, complication rates and duration of hospital stay were found significantly superior to those of the open technique group. While there was no mortality seen and wound complications as a morbidity were 0 % in the L-VHR (n = 0 and 20 % in C-VHR group (n = 4. In the comparison of mean operative time, the duration of surgery was significantly shorter in the laparoscopic repair group (67.25±19.23 min compared to the open technique group (91.50±24.87 min (p=0.001. Laparoscopic repair was associated with less postoperative pain (4.35±1.03 vs 5.60±1.31, p=0.002, lesser postoperative complications (5% vs. 35%, p=0.044, and shorter

    Metronomic chemotherapy (MC) consists of the administration of a low dose of chemotherapy on a daily or weekly basis without a long break to achieve an antitumoral effect through an antiangiogenic effect or stimulation of the immune system. The potential effect of MC with continuous oral cyclophosphamide and methotrexate in patients with high-grade operable osteosarcomas (OSTs) of the extremities was investigated. Patients with high-grade OSTs who were 30 years old or younger were eligible for registration at diagnosis. Eligibility for randomization included 1) nonmetastatic disease and 2) complete resection of the primary tumor. The study design included a backbone of 10 weeks of preoperative therapy with methotrexate, adriamycin, and platinum (MAP). After surgery, patients were randomized between 2 arms to complete 31 weeks of MAP or receive 73 weeks of MC after MAP. The primary endpoint was event-free survival (EFS) from randomization. There were 422 nonmetastatic patients registered (May 2006 to July 2013) from 27 sites in 3 countries (Brazil, Argentina and Uruguay), and 296 were randomized to MAP plus MC (n = 139) or MAP alone (n = 157). At 5 years, the EFS cumulative proportions surviving in the MAP-MC group and the MAP-alone group were 61% (standard error [SE], 0.5%) and 64% (SE, 0.5%), respectively, and they were not statistically different (Wilcoxon [Gehan] statistic = 0.724; P =.395). The multivariate analysis showed that necrosis grades 1 and 2, tumor size, and amputation were associated with shorter EFS. According to the current follow-up, EFS with MAP plus MC is not statistically superior to EFS with MAP alone in patients with high-grade, resectable OSTs of the extremities.

    Background Laparoscopic total extraperitoneal (TEP) inguinal hernia repair is a well-known approach to inguinal hernia repair that is usually performed under general anesthesia (GA). To date, no reports compare the efficacy of spinal anesthesia (SA) with that of GA for laparoscopic hernia repairs. The purpose of this study was to compare the surgical outcome of TEP inguinal hernia repair performed when the patient was treated under SA with that performed under GA. Materials and methods Between July 2015 and July 2016, 50 patients were prospectively randomized to either the GA TEP group (Group I) or the SA TEP group (Group II). Propofol, fentanyl, rocuronium, sevoflurane, and tracheal intubation were used for GA. Hyperbaric bupivacaine (15 mg) and fentanyl (10 µg) were used for SA to achieve a sensorial level of T3. Intraoperative events related to SA, operative and anesthesia times, postoperative complications, and pain scores were recorded. Each patient was asked to evaluate the anesthetic technique by using a direct questionnaire filled in 3 months after the operation. Results All the procedures were completed by the allocated method of anesthesia as there were no conversions from SA to GA. Pain was significantly less for 1 h (Pinguinal hernia repair can be safely performed under SA, and SA was associated with less postoperative pain, better recovery, and better patient satisfaction than GA.

    Full Text Available Abstract Background An acute complication of thyroidectomy is fatal hematoma, which can produce an upper airway obstruction needing immediate intubation or tracheostomy. After neck surgery, we usually apply a pressure dressing with a non-woven, adhesive fabric to reduce bleeding and fluid collection at the operative bed. We conducted a prospective, randomized, controlled study to evaluate a pressure vs. a non-pressure dressing after thyroid surgery by monitoring blood and serum in the operative bed. Methods We studied 108 patients who underwent 116 thyroid surgeries at Srinagarind Hospital, Khon Kaen University, between December 2006 and September 2007. The patients were randomized to either the pressure dressing or non-pressure dressing group. Ultrasound of the neck was performed 24 ± 3 hours after surgery. The volume of fluid collection in the operative bed was calculated. All patients were observed for any post-operative respiratory distress, wound complications, tingling sensation or tetany. Results The distributions of age, sex, surgical indications and approaches were similar between the two groups. There was no statistically significant difference in the volume of fluid collection in the operative bed (p = 0.150 and the collected drained content (p = 0.798. The average time a drain was retained was 3 days. One patient in the pressure dressing group suffered cutaneous bruising while one patient in the non-pressure dressing group developed immediate hemorrhage after the skin sutures. Conclusion Pressure dressing after thyroidectomy does not have any significant impact on decreasing fluid collection at the operative bed. The use of pressure dressing after thyroidectomy may not therefore be justified. Trial Registration NCT00400465, ISRCTN52660978

    Full Text Available Background: Shivering is very uncomfortable and distressing for the patient, anaesthesiologist and the surgeon, especially when the patient is under regional anaesthesia. Aim and Objectives: The present study was designed to evaluate the efficacy of butorphanol and tramadol in the control of shivering under spinal anaesthesia and to compare their side effects. To compare the efficacy, potency, response time, hemodynamic alterations, and adverse effects of intravenously administered tramadol and butorphanol for relief of shivering occurring during spinal anaesthesia. Material and Methods: This randomized prospective study was conducted in 100 patients who developed shivering under spinal anaesthesia during various abdominal, orthopaedic, urological and gynaecological procedures. Patients with fever, acute infections, drug allergy and compromised cardiorespiratory functions were not included in the study. On shivering, patients were randomly allocated in two groups of 50 patients each who received intravenously 1mg of butorphanol or 50 mg of tramadol in a double blinded manner. Control of shivering, time taken for cessation, recurrence, hemodynamic changes, axillary temperatures and side effects were noted and compared for both the groups. Collected data were analysed using Chi square test and Student's unpaired t test. Results: All patients were relieved of shivering after butorphanol, 58% within 1 min, 82% within 3min and 100% within 5 min. Tramadol relieved shivering in 98% of patients, 32% within 1 min, 60% within 3 min, 98% within 5 mins (p<0.05. There was higher incidence of side effects like nausea and vomiting with tramadol (16% and 12% respectively as compared to butorphanol. Conclusion: Both the drugs, tramadol and butorphanol are effective to control shivering after spinal anaesthesia. Butorphanol is better as compared to tramadol in treating shivering under spinal anaesthesia because of its quicker onset of action, higher success rate

    To evaluate whether suction or water seal is superior in the management of chest tubes after pulmonary resection. A prospective, randomized, controlled trial. After an initial, brief period of suction, patients were randomized to water seal or - 20 cm H(2)O suction. University hospital. Sixty-eight patients who underwent wedge resection, segmentectomy, or lobectomy were included in the study. Those patients who underwent reoperative surgery or lung volume reduction surgery were excluded. There were 34 patients in each group. The two groups were evenly matched for age, sex, operation performed, severity of lung disease, and nutritional status. Fifteen patients in each group (44%) had an air leak at the completion of surgery. The duration of the air leak was shorter in the water seal group than in the suction group (mean +/- SEM, 1.50 +/- 0.32 days vs 3.27 +/- 0.80 days, respectively; p = 0.05). The mean times to removal of chest tubes were 3.33 +/- 0.35 days in the water seal group and 5.47 +/- 0.98 days in the suction group (p = 0.06). The length of stapled parenchyma was measured for each patient and averaged 24.9 cm for the water seal group and 18.5 cm for the suction group (p = 0.18). When corrected for the length of staple lines, the duration of air leaks and days with chest tube were dramatically lower in the water seal group (p = 0.02 and p = 0.02, respectively). Placing chest tubes on water seal after a brief period of suction after pulmonary resection shortens the duration of the air leak and likely decreases the time that the chest tubes remain in place. Adoption of this practice may result in lower morbidity and lower hospital costs.

    Wu-Ling-San (WLS) formula has been proved to prevent calcium oxalate nephrolithiasis both in vitro and in vivo. This is the first prospective, randomized and placebo-controlled clinical trial of WLS in calcium oxalate nephrolithiasis prevention. All patients who enrolled were asked to drink enough fluid to urinate at least 2 L daily during the study period. A 24-hour urine collection was performed to establish the baseline levels of multiple urinary parameters before taking the medicine. The patients were randomized and divided into two groups. The medication group took 2 gm WLS formula three times daily for 1 month. The control group took 2 gm placebo three times daily for 1 month. A 24-hour urine collection was performed to evaluate multiple urinary and serum parameters from all patients during the study period. A total of 39 patients were enrolled and 28 patients completed the study. Fourteen patients were allocated to WLS group and 14 patients to placebo group. After treatment, the mean urine output level increased to 2796.4 ± 525.7 ml/day (percentage of change, 13.9 %) in the WLS formula group. With placebo therapy, the mean decreased slightly to 2521.4 ± 762.7ml/day (percentage of change, -5.7 %). The percentage of change was significantly different between the two groups (independent t-test, P=0.02). No patient complained of side effects, such as fatigue, dizziness, musculoskeletal symptoms, or gastrointestinal disturbance. WLS formula is a promising adjunct to surgical and medical management of kidney stones. Active therapy with WLS formula has a positive effect on diuresis without leading to electrolyte imbalance.

    This randomized double blind study was conducted prospectively to determine whether coblation tonsillectomy fared better than the conventional dissection method in terms of postoperative pain, bleeding, and rapidity of healing in adult Indian patients undergoing tonsillectomy. Sixty adult patients undergoing tonsillectomy for benign indications were randomized to have one tonsil removed by subcapsular radiofrequency ablation method and the other by conventional dissection method. The operative time and blood loss was noted for each side. Patients were evaluated at 6, 12, 24, 48, 72 h and then on 7th and 20th postoperative day for postoperative pain (by visual analog scale), bleeding, and tonsillar fossa healing. Statistical comparison was done using appropriate tests. The two groups were demographically matched. It took longer to perform the coblation procedure (15 vs 11 min) (P > 0.05). The operative blood loss on the radiofrequency side was 11 ml, vs 34 ml on the conventional side (P = 0.009). 77% patients said that the coblation side was less painful for the overall 20-day recovery period. There were significant differences seen at 6, 12, 24, 48, and 72 h in terms of postoperative pain scores. Beyond that, the pain was consistently less on the coblation side, but the difference was not significant. There was no case of reactionary or secondary hemorrhage in either arm. The healing took longer on the radiofrequency side. Coblation tonsillectomy is an easy to learn technique with significantly reduced operative blood loss and postoperative pain. Longer operative times maybe further reduced with experience.

    The rate of prophylactic mastectomies (PM) is increasing. Patients generally report high levels of health related quality of life and satisfaction after the procedure, whereas body image perception and sexuality may be negatively affected. The aim of the study was to evaluate the interest in physical therapy as a means of improving body image and sexuality in women after PM. Patients undergoing PM at Karolinska University Hospital between 2006 and 2010 were eligible. The following patient-reported outcome measures were used at study baseline and 2 years postoperatively: the body image scale (BIS), the sexual activity questionnaire (SAQ), the short-form health survey (SF-36), the hospital anxiety and depression scale (HAD), and a study specific "pain/motion/sensation scale". Out of 125 patients invited to participate in this prospective randomized study, 43 (34%) consented and were randomized into the intervention (n = 24, 56%) or control (n = 19, 44%) groups. There were no statistically significant between-group differences found with respect to BIS, SAQ, SF-36, HAD, and "pain/motion/sensation". Two years postoperatively, more than half of the patients in both groups reported problems like feeling less attractive, less sexually attractive, their body feeling less whole, and being dissatisfied with their body. A majority marked a decreased sensation in breast area. The interest in a physiotherapy intervention was limited among women who had undergone PM. The intervention did not show any substantial effects. A large proportion of patients reported specific body image related and pain/motion/sensation problems postoperatively.

    Full Text Available BACKGROUND: This prospective randomized double blind study was conducted to evaluate the effect and safety of intrathecal dexmedetomidine added to isobaric ropivacaine. MATERIALS AND METHODS: 120 adult female patients, who underwent vaginal hysterectomies, were randomly allocated to receive intrathecally either 3 ml of 0.75% isobaric ropivacaine + 0.5 ml normal saline (Group R or 3 ml of 0.75% isobaric ropivacaine +5 μg dexmedetomidine in 0.5 ml of normal saline (Group D. Following intrathecal administration, duration of onset of sensory and motor blockade, maximum dermatomal level achieved, duration of analgesia, hemodynamic parameters and incidence of side effects were observed. RESULTS: Duration of onset of sensory block upto T10, T8 and the highest level of block achieved i. e. T6 were similar in both the groups. The mean time of sensory regression to S2 was 297.71±34.11 min in group D and 221.35±22.70 min in group R. Time to achieve Bromage score 0 was significantly slower with the addition of dexmedetomidine (229.37±28.74 min in group R vs. 258.55±30.46 min in group D. Duration of postoperative analgesia was significantly greater in group D (270.00±38.75 min as compared to group R (174.77±22.31 min. The maximum VAS score for pain was less in group D (4.42±0.69 as compared to group R (7.03±0.78. There were no significant difference in hemodynamic parameters and incidence of side effects in both the groups. CONCLUSION: The addition of dexmedetomidine to ropivacaine intrathecally produces significantly longer sensory and motor blockade along with better postoperative analgesia, and excellent hemodynamic stability without any significant side effects.

    The aim of this work was to compare the efficacy of two different dose fractionation schedules for radiotherapy of patients with calcaneodynia. Between February 2006 and April 2010, 457 consecutive evaluable patients were recruited for this prospective randomized trial. All patients received radiotherapy using the orthovoltage technique. One radiotherapy series consisted of 6 single fractions/3 weeks. In case of insufficient remission of pain after 6 weeks a second radiation series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before, immediately after, and 6 weeks after radiotherapy using a visual analogue scale (VAS) and a comprehensive pain score (CPS). The overall response rate for all patients was 87 % directly after and 88 % 6 weeks after radiotherapy. The mean VAS values before, immediately after, and 6 weeks after treatment for the 0.5 and 1.0 Gy groups were 65.5 {+-} 22.1 and 64.0 {+-} 20.5 (p = 0.188), 34.8 {+-} 24.7 and 39.0 {+-} 26.3 (p = 0.122), and 25.1 {+-} 26.8 and 28.9 {+-} 26.8 (p = 0.156), respectively. The mean CPS before, immediately after, and 6 weeks after treatment was 10.1 {+-} 2.7 and 10.0 {+-} 3.0 (p = 0.783), 5.6 {+-} 3.7 and 6.0 {+-} 3.9 (p = 0.336), 4.0 {+-} 4.1 and 4.3 {+-} 3.6 (p = 0.257), respectively. No statistically significant differences between the two single dose trial arms for early (p = 0.216) and delayed response (p = 0.080) were found. Radiotherapy is an effective treatment option for the management of calcaneodynia. For radiation protection reasons, the dose for a radiotherapy series is recommended not to exceed 3-6 Gy. (orig.)

    To evaluate the possible effects of Tribulus terrestris herbal medicine in the erectile dysfunction treatment and to quantify its potential impact on serum testosterone levels. Prospective, randomized, double-blind and placebo-controlled study including thirty healthy men selected from 100 patients who presented themselves spontaneously complaining of erectile dysfunction, ≥ 40 years of age, nonsmokers, not undergoing treatment for prostate cancer or erectile dysfunction, no dyslipidemia, no phosphodiesterase inhibitor use, no hormonal manipulation and, if present hypertension and/or diabetes mellitus should be controlled. International Index of Erectile Function (IIEF-5) and serum testosterone were obtained before randomization and after 30 days of study. Patients were randomized into two groups of fifteen subjects each. The study group received 800 mg of Tribulus terrestris, divided into two doses per day for thirty days and the control group received placebo administered in the same way. The groups were statistically equivalent in all aspects evaluated. The mean (SD) age was 60 (9.4) and 62.9 (7.9), P = .36 for intervention and placebo groups, respectively. Before treatment, the intervention group showed mean IIEF-5 of 13.2 (5-21) and mean total testosterone 417.1 ng/dl (270.7-548.4 ng/dl); the placebo group showed mean IIEF-5 of 11.6 (6-21) and mean total testosterone 442.7 ng/dl (301-609.1 ng/dl). After treatment, the intervention group showed mean IIEF-5 of 15.3 (5-21) and mean total testosterone 409.3 ng/dl (216.9-760.8 ng/dl); the placebo group showed mean IIEF-5 of 13.7 (6-21) and mean total testosterone 466.3 ng/dl (264.3-934.3 ng/dl). The time factor caused statistically significant changes in both groups for IIEF-5 only (P = .0004), however, there was no difference between the two groups (P = .7914). At the dose and interval studied, Tribulus terrestris was not more effective than placebo on improving symptoms of erectile dysfunction or serum total

Methodology: It was an open label, randomized, comparative, parallel group and multi-center clinical study. Total 47 subjects were randomly assigned to Group-A (AHPL/AYTOP/0113 cream and 42 subjects were randomly assigned to Group-B (Framycetin sulphate cream. All the subjects were advised to apply study drug, thrice daily for 21 days or up to complete wound healing (whichever was earlier. All the subjects were called for follow up on days 2, 4, 7, 10, 14, 17 and 21 or up to the day of complete wound healing. Data describing quantitative measures are expressed as mean ± SD. Comparison of variables representing categorical data was performed using Chi-square test. Results: Group-A subjects took significantly less (P < 0.05 i.e., (mean 7.77 days than (mean 9.87 days of Group-B subjects for wound healing. At the end of the study, statistically significant better (P < 0.05 results were observed in Group-A than Group-B in mean wound surface area, wound healing parameters and pain associated with wound. Excellent overall efficacy and tolerability was observed in subjects of both the groups. No adverse event or adverse drug reaction was noted in any subject of both the groups. Conclusion: AHPL/AYTOP/0113 cream proved to be superior to Framycetin sulphate cream in healing of acute wounds.

    Radioactive seed localization (RSL) has emerged as an alternative to wire localization (WL) in patients with nonpalpable breast cancer. Few studies have prospectively evaluated patient satisfaction and outcomes with RSL. We report the results of a randomized trial comparing RSL to WL in our community hospital. We prospectively enrolled 135 patients with nonpalpable breast cancer between 2011 and 2014. Patients were randomized to RSL or WL. Patients rated the pain and the convenience of the localization on a 5-point Likert scale. Characteristics and outcomes were compared between groups. Of 135 patients enrolled, 10 were excluded (benign pathology, palpable cancer, mastectomy, and previous ipsilateral cancer) resulting in 125 patients. Seventy patients (56%) were randomized to RSL and 55 (44%) to WL. Fewer patients in the RSL group reported moderate to severe pain during the localization procedure compared to the WL group (12% versus 26%, respectively, p = 0.058). The overall convenience of the procedure was rated as very good to excellent in 85% of RSL patients compared to 44% of WL patients (p patient satisfaction with RSL provides another incentive for surgeons to strongly consider RSL as an alternative to WL.

This study was designed to assess the outcome of navigated TKA in comparison with conventional implantation with the focus on rotational component position and clinical mid-term results. Methods In a prospectively randomized single-blinded approach, 90 patients with primary gonarthrosis were assigned to three different groups. Thirty patients each were assigned to NexGen LPS without and with navigation (groups 1 and 2, and 30 patients to navigation with the Stryker Scorpio PS (group 3. The navigation system used was the imageless Stryker KneeTrac, version 1.0. Clinical outcome was assessed by a blinded observer applying the Knee Society Score (KSS and a visual analogue scale (VAS for pain. CT scans and radiographs were conducted prior to and 12 weeks after index surgery. Results Seventy-nine patients were available for clinical evaluation at 3 ± 0.4 years follow-up. Four implants had to be revised for early loosening or infection (4.4%. Four patients had died and three patients were not able to follow the invitation for clinical assessment. Functional results in the KSS were significantly lower after navigated TKA. Operation time and incisions with navigation were significantly longer. Significantly less radiological outliers with navigation were found for coronal alignment of the femur, only. Conclusion In this series, no beneficial effect for navigation in TKA could be shown assessing clinical data, as functional results in the presented series seemed to be lower after first generation navigated TKA. The clinical mid- to long-term value of navigation remains to be evaluated in larger patient series or meta-analyses at longer follow-up. Trial registration number DRKS 00000430

    To compare the anesthetic efficacy of 1.8 mL of 2% lidocaine with 1:200,000 epinephrine, 4% articaine with 1:100,000 epinephrine, and 0.5% bupivacaine with 1:200,000 epinephrine on producing inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis. A total of 91 adult patients who were actively experiencing mandibular molar pain were involved in this study. The patients were randomly divided into three groups on the basis of the anesthetic solution used. The first group received IANB with 1.8 mL of 2% lidocaine with 1:200,000 epinephrine, the second group received IANB with 4% articaine with 1:100,000 epinephrine, and the third group received IANB with 0.5% bupivacaine with 1:200,000 epinephrine. After 15 minutes of IANB, conventional endodontic access preparation was started. The pain during the treatment was noted on a Heft-Parker visual analog scale (HP VAS). The primary outcome measure was anesthetic success, and anesthesia was considered successful if the patient reported no pain or weak/mild pain (HP VAS score 2% lidocaine, 4% articaine, and 0.5% bupivacaine were 23%, 33%, and 17%, respectively. The differences were statistically insignificant (P > .05). The 2% lidocaine solution used for IANB had similar success rates when compared with 4% articaine and 0.5% bupivacaine.

    Background and purpose: The goal of the present study was to evaluate the efficacy of two different dose-fractionation schedules for radiotherapy (RT) of patients with painful elbow syndrome. Patients and methods: Between February 2006 and February 2010, 199 consecutive evaluable patients were recruited for this prospective randomized trial. All patients received RT in orthovoltage technique. One RT course consisted of 6 single fractions/3 weeks. In case of insufficient remission of pain after 6 weeks a second radiation series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before, right after, and 6 weeks after RT by a visual analogue scale (VAS) and a comprehensive pain score (CPS). Results: The overall response rate for all patients was 80% direct after and 91% 6 weeks after RT. The mean VAS values before, after and 6 weeks after treatment for the 0.5 and 1.0 Gy groups were 59.6 {+-} 20.2 and 55.7 {+-} 18.0 (p = 0.463), 32.1 {+-} 24.5 and 34.4 {+-} 22.5 (p = 0.256), and 27.0 {+-} 27.7 and 23.5 {+-} 21.6 (p = 0.818). The mean CPS before, after, and 6 weeks after treatment was 8.7 {+-} 2.9 and 8.1 {+-} 3.1 (p = 0.207), 4.5 {+-} 3.2 and 5.0 {+-} 3.4 (p = 0.507), 3.9 {+-} 3.6 and 2.8 {+-} 2.8 (p = 0.186), respectively. No statistically significant differences between the two single dose trial arms for early (p = 0.103) and delayed response (p = 0.246) were found. Conclusion: RT is an effective treatment option for the management of benign painful elbow syndrome. For radiation protection reasons the dose for a RT series is recommended not to exceed 3.0 Gy.

    Full Text Available Abstract Background Total knee arthroplasty (TKA is often associated with a severe local inflammatory reaction which, unless controlled, leads to persistent pain up to one year after surgery. Standard and accelerated rehabilitation protocols are currently being implemented after TKA, but no consensus exists regarding the long-term effects. Biophysical stimulation with pulsed electromagnetic fields (PEMFs has been demonstrated to exert an anti-inflammatory effect, to promote early functional recovery and to maintain a positive long-term effect in patients undergoing joint arthroscopy. The aim of this study was to evaluate whether PEMFs can be used to limit the pain and enhance patient recovery after TKA. Methods A prospective, randomized, controlled study in 30 patients undergoing TKA was conducted. Patients were randomized into experimental PEMFs or a control group. Patients in the experimental group were instructed to use I-ONE stimulator 4hours/day for 60days. Postoperatively, all patients received the same rehabilitation program. Treatment outcome was assessed using the Knee Society Score, SF-36 Health-Survey and VAS. Patients were evaluated pre-operatively and one, two, six and 12 months after TKA. Joint swelling and Non Steroidal Anti Inflammatory Drug (NSAID consumption were recorded. Comparisons between the two groups were carried out using a two-tail heteroschedastic Student’s t-test. Analysis of variance for each individual subject during the study was performed using ANOVA for multiple comparisons, applied on each group, and a Dunnet post hoc test. A p value  Results Pre-operatively, no differences were observed between groups in terms of age, sex, weight, height, Knee-Score, VAS, SF-36 and joint swelling, with the exception of the Functional Score. The Knee-Score, SF-36 and VAS demonstrated significantly positive outcomes in the I-ONE stimulated group compared with the controls at follow-ups. In the I-ONE group, NSAID use was

    There is no consensus on the treatment of chronic low back pain of disc origin in the medical literature. The few prospective, randomized, controlled studies evaluating the effectiveness of caudal epidural steroid injections (CESI) have obtained contradictory results. The aim of this study is to evaluate the efficacy of CEI in reducing pain and improving the associated disability. This is a prospective, randomized, case-control study of a group of 46 patients with chronic low back disc pain. Patients were randomly allocated into 2 groups to either receive fluoroscopy guided CESI (CESI-group), or oral non-steroidal anti-inflammatory drugs (NSAID-group). All patients were clinically evaluated at 4, 12, and 24 weeks, and according to the indications of the Spanish Society for Study of Diseases of the Spine (GEER). Lumbar pain, measured by the visual analog scale (VAS) and the Oswestry Low Back Pain Disability Questionnaire (ODQ), did not improve significantly during follow-up in any of the two study groups (P>.05). Younger patients, women, patients with shorter duration of symptoms, low physical job demand, without leg pain, and sport-active, included in CESI-group showed a trend towards better results, but none reached statistical significance (P>.05). The present study has not demonstrated the superiority of CESI over NSAIDs in treating chronic low back pain of disc origin. While CESI could show some improvement in patients with degenerative lumbar disc disease, we consider it should be used with caution, informing patients about realistic expectations on the success of treatment.

    Quantum random-number generators (QRNGs) can offer a means to generate information-theoretically provable random numbers, in principle. In practice, unfortunately, the quantum randomness is inevitably mixed with classical randomness due to classical noises. To distill this quantum randomness, one needs to quantify the randomness of the source and apply a randomness extractor. Here, we propose a generic framework for evaluating quantum randomness of real-life QRNGs by min-entropy, and apply it to two different existing quantum random-number systems in the literature. Moreover, we provide a guideline of QRNG data postprocessing for which we implement two information-theoretically provable randomness extractors: Toeplitz-hashing extractor and Trevisan's extractor.

    One of the most important considerations in the care of thoracic surgery patients is the control of pain, which leads to increased morbidity and relevant mortality. Between February and May 2009, 60 patients undergoing full muscle-sparing posterior minithoracotomy were prospectively randomized into two groups, according to the thoracotomy closure techniques. In the first group (group A), two holes were drilled into the sixth rib using a hand perforator, and sutures were passed through the holes in the sixth rib and were circled from the upper edge of the fifth rib, thereby compressing the intercostal nerve underneath the fifth rib. In the second group (group B), the intercostal muscle underneath the fifth rib was partially dissected along with the intercostal nerve, corresponding to the holes on the sixth rib. Two 1/0 polyglactin (Vicyrl) sutures were passed through the holes in the sixth rib and above the intercostal nerve. There were 30 patients in each group. The visual analog score, observer verbal ranking scale (OVRS) scores for pain, and Ramsay sedation scores were used to follow-up on postoperative analgesia and sedation. The von Frey hair test was used to evaluate hyperalgesia of the patients. The patients in group B had lower visual analog scores at rest and during coughing. The patients in group B had lower OVRS scores than group A patients. The groups were not statistically different in terms of the Ramsay sedation scores and von Frey hair tests. Thoracotomy closure by a technique that avoids intercostal nerve compression significantly decreases post-thoracotomy pain. Copyright © 2010 European Association for Cardio-Thoracic Surgery.

    To compare differences in subjective glare and spherical aberration between five foldable intraocular lenses (IOLs) made of different materials and to different designs. This prospective study comprised 175 cataract patients who underwent phacoemulsification and were randomized to receive one of five types of foldable IOL (AcrySof MA30BA, Alcon; Sensar AR40, AMO; AcrySof SA30AL, Alcon; Sensar AR40e, AMO, and Tecnis Z9000, Pharmacia & Upjohn). All patients received a questionnaire investigating the incidence of subjective photic phenomena. Two months postoperatively, we collected data regarding subjective glare and evaluated pupil size, visual acuity and wavefront aberration of the cornea and eye. With regard to difficulty in performing ordinary activities under different light conditions and light and dark adaptation, the difference between the groups was not significant (p > 0.05, chi-squared test). With respect to difficulty in driving at night, the MA30BA group had a significant higher incidence of photic phenomena than the SA30AL, AR40e and Z9000 groups (p < 0.05, chi-squared test). Wavefront measurements revealed a significant difference between the Z9000, AR40e and SA30AL groups, which showed the lowest values, and the MA30BA group, which showed the highest value (p < 0.05, anova with Tamhane posthoc test). New generation IOLs such as the Pharmacia Z9000, AMO AR40e and AcrySof SA30AL have a lower incidence of glare and spherical aberrations; however, their impact on future IOL design should be conditioned by further data, especially regarding posterior capsule opacification.

    Full Text Available Background: Postoperative morbidity and inhospital length of stay are considered major determinants of total health care expenditure associated with thoracic operations. The aim of this study was to prospectively evaluate the role of video-assisted thoracic surgery (VATS compared to mini-muscle-sparing thoracotomy in facilitating early recovery and hospital discharge after pulmonary sublobar wedge resections. Patients and Methods: A total number of 120 patients undergoing elective pulmonary sublobar wedge resection were randomly assigned to VATS (n = 60 or mini-muscle-sparing thoracotomy (n = 60. The primary endpoint was time to hospital discharge. Postoperative complications, cardiopulmonary morbidity and 30-day mortality served as secondary endpoints. Results: Patients' baseline demographic and clinical data did not differ among study arms as well as the number of pulmonary segments resected and the morphology of the nodular lesions. Total hospital stay was significantly shorter in patients assigned to the thoracoscopic technique as opposed to those who were operated using the mini-muscle-sparing thoracotomy approach (4 ± 0.6 versus 4.4 ± 0.6 days respectively, P = 0.006. Multivariate analysis revealed that VATS approach was inversely associated with longer inhospital stay whereas the number of resected segments was positively associated with an increased duration of hospitalization. Patients in the VATS group were less likely to develop atelectasis (≥1 lobe compared to those who underwent thoracotomy (0% versus 6.7% respectively, P = 0.042. Kaplan-Meier analysis revealed similar 30-day mortality rates in both study arms (Log-rank P = 0.560. Conclusion: VATS was associated with shorter duration of hospitalization positively affecting the patients' quality of life and satisfaction. Significant suppression of the total cost of recovery after thoracoscopic pulmonary resections is expected.

    We report on a prospective randomized study of coralline hydroxyapatite (CH) used as backfill for iliac-crest donor sites. Autogenous iliac-crest bone graft is routinely harvested for spinal fusion. Donor-site morbidity is underappreciated; the presumption is that donor sites regenerate. In this study, we assessed the biological viability of the backfill CH (Pro OsteonTM Implant 500 Hydroxyapatite Bone Void Filler; Interpore, Irvine, Calif) and compared donor-site morbidity after harvest. Twelve patients (11 men, 1 woman) were enrolled: 5 in the backfill group and 7 in the no-backfill group. As part of routine evaluations done preoperatively and 6 weeks, 3 months, 6 months, and 1 year postoperatively, plain radiographs and computed tomography (CT) scans were used to assess bone ingrowth, and technetium bone scans were used to assess biological activity. Postoperative pain analysis was also done. Ten patients (9 men, 1 woman) completed the study. Of the 4 completers in the backfill group, 3 (75%) showed bony ingrowth on plain radiographs and CT scans at 1 year; the fourth patient showed bony ingrowth only on plain radiographs. All 4 patients showed biological activity on bone scans and reported mild pain to no pain. Of the 6 completers in the no-backfill group, 1 (17%) showed bony ingrowth on plain radiographs and CT scans. No patient showed biological activity on bone scans at 1 year. CH aids in iliac-crest healing after bone-graft harvesting by acting as a biological osteoconductive matrix. Postoperative pain at the bone-graft site is potentially reduced. More studies of larger numbers of patients are needed to assess the true long-term benefits of this material in a clinical setting.

    Patients with insomnia may present with mild and often unrecognized obstructive sleep apnea (OSA). To evaluate both subjective and objective outcomes of patients with complaints of insomnia and mild OSA who receive surgical treatment for OSA versus behavioral treatment with cognitive behavioral therapy for insomnia (CBT-I). Prospective study with crossover design of 30 patients with complaints of insomnia and mild OSA. Thirty subjects, matched for age and gender, were randomized with stratification to receive either CBT-I or surgical treatment of OSA as primary treatment. Patients were reassessed after completing the initial intervention and reassigned if agreeable to the alternative treatment option and assessed again on completion of both treatment arms. Outcome measures included clinical impression, Epworth Sleepiness Scale (ESS) score, Fatigue Severity Scale (FSS) score, and polysomnography (PSG) results. Surgery resulted in greater improvements in total sleep time (TST), slow wave sleep and REM sleep duration, respiratory disturbance index, apnea-hypopnea index, minimum oxygen saturation, FSS, and ESS. CBT-I also improved TST and resulted in shorter sleep latency. Surgical intervention for the management of patients with complaints of insomnia and mild OSA demonstrated greater improvement in both subjective and objective outcome measures. Initial treatment of underlying OSA in patients with insomnia was more successful in improving insomnia than CBT-I alone. However CBT-I as initial treatment improved TST compared to baseline; following surgical intervention, it had the additional benefit of further increasing TST and helped to control sleep onset difficulties that may be related to conditioning due to unrecognized symptoms of mild OSA.

    We have evaluated the use of a synthetic porous ceramic (Triosite) as a substitute for bone graft in posterior spinal fusion for idiopathic scoliosis. In a prospective, randomised study 341 patients at five hospitals in the UK and France were randomly allocated either to autograft from the iliac crest or rib segments (171) or to receive Triosite blocks (170). All patients were assessed after operation and at 3, 6, 12 and 18 months. The two groups were similar with regard to all demographic and baseline variables, but the 184 treated in France (54%) had Cotrel-Dubouset instrumentation and the 157 treated in the UK usually had Harrington-Luque implants. In the Triosite group the average Cobb angle of the upper curve was 56 degrees, corrected to 24 degrees (57%). At 18 months, the average was 26 degrees (3% loss). In the autograft group the average preoperative upper curve of 53 degrees was corrected to 21 degrees (60%). At 18 months the mean curve was 25 degrees (8% loss). Pain levels after operation were similar in the two groups, being mild in most cases. In the Triosite group only three patients had problems of wound healing, but in the autograft group, 14 patients had delayed healing, infection or haematoma in the spinal wound. In addition, 15 autograft patients had pain at the donor site at three months. Seven had infections, two had haematoma and four had delayed healing. The haematological and serum biochemistry results showed no abnormal trends and no significant differences between the groups. There were no adverse events related to the graft material and no evidence of allergenicity. Our results suggest that Triosite synthetic porous ceramic is a safe and effective substitute for autograft in these patients. Histological findings on biopsy indicate that Triosite provides a favourable scaffolding for the formation of new bone and is gradually incorporated into the fusion mass.

To date, no reports compare the efficacy of spinal anesthesia (SA with that of GA for laparoscopic hernia repairs. The purpose of this study was to compare the surgical outcome of TEP inguinal hernia repair performed when the patient was treated under SA with that performed under GA. Materials and methods: Between July 2015 and July 2016, 50 patients were prospectively randomized to either the GA TEP group (Group I or the SA TEP group (Group II. Propofol, fentanyl, rocuronium, sevoflurane, and tracheal intubation were used for GA. Hyperbaric bupivacaine (15 mg and fentanyl (10 µg were used for SA to achieve a sensorial level of T3. Intraoperative events related to SA, operative and anesthesia times, postoperative complications, and pain scores were recorded. Each patient was asked to evaluate the anesthetic technique by using a direct questionnaire filled in 3 months after the operation. Results: All the procedures were completed by the allocated method of anesthesia as there were no conversions from SA to GA. Pain was significantly less for 1 h (P<0.0001 and 4 h (P=0.002 after the procedure for the SA and GA groups, respectively. There was no difference between the two groups regarding complications, hospital stay, recovery, or surgery time. Generally, patients were more satisfied with SA than GA (P<0.020. Conclusion: TEP inguinal hernia repair can be safely performed under SA, and SA was associated with less postoperative pain, better recovery, and better

    The purpose of this study was to compare the structural outcomes of a single-row rotator cuff repair and double-row suture bridge fixation after arthroscopic repair of a full-thickness supraspinatus rotator cuff tear. We evaluated with diagnostic ultrasound a consecutive series of ninety shoulders in ninety patients with full-thickness supraspinatus tears at an average of 10 months (range, 6-12) after operation. A single surgeon at a single hospital performed the repairs. Inclusion criteria were full-thickness supraspinatus tears less than 25 mm in their anterior to posterior dimension. Exclusion criteria were prior operations on the shoulder, partial thickness tears, subscapularis tears, infraspinatus tears, combined supraspinatus and infraspinatus repairs and irreparable supraspinatus tears. Forty-three shoulders were repaired with single-row technique and 47 shoulders with double-row suture bridge technique. Postoperative rehabilitation was identical for both groups. Ultrasound criteria for healed repair included visualization of a tendon with normal thickness and length, and a negative compression test. Eighty-three patients were available for ultrasound examination (40 single-row and 43 suture-bridge). Thirty of 40 patients (75%) with single-row repair demonstrated a healed rotator cuff repair compared to 40/43 (93%) patients with suture-bridge repair (P = .024). Arthroscopic double-row suture bridge repair (transosseous equivalent) of an isolated supraspinatus rotator cuff tear resulted in a significantly higher tendon healing rate (as determined by ultrasound examination) when compared to arthroscopic single-row repair.

    Introduction Spastic cerebral palsy (CP) is the most common form of CP. Diazepam and Baclofen are the most commonly used oral drugs to manage spasticity. Study was designed to evaluate and compare their effects and safety in CP children. Aim Study was aimed to assess and compare outcome of oral Diazepam and Baclofen in spastic cerebral palsy children in terms of extent of reduction of spasticity and side effects profile. Materials and Methods Randomized prospective follow-up study was done for one year after giving Diazepam and Baclofen in weekly incremental doses upto recommended maximum dose to 60 children for three months. Two primary outcome measures were spasticity reduction and adverse effect profile. Spasticity reduction was measured by Modified Ashworth’s Scale (MAS) and Range of Motion improvement (ROM). Results After random allocation, there was no baseline difference between groups. Mean MAS score improved from 1.96±0.4 at baseline to 1.63±0.40 and 1.41± 0.36 at 1 month and 3 months for Diazepam and from 1.84±0.64 to 1.57±0.59 and 1.31± 0.48 respectively for Baclofen. Within the group reduction was significant with p-value = 0.0001. Intergroup comparison showed no statistically significant difference with p-value of 0.48 and 0.22 at 1 and 3 months. Baseline ROM showed significant improvement at 1 and 3 months with p value of 0.004 and 0.001 for Diazepam and 0.01 and 0.000 for Baclofen respectively with no statistically significant difference among two groups. Drowsiness was most common observed side effect in both the groups. Conclusion Patients showed significant improvement in spasticity as measured by Mean MAS score and range of motion in Diazepam as well as Baclofen group. Both drugs were found safe for use in children. Study couldn’t establish any difference between the two drugs. However studies with bigger sample size and longer follow- up assessing functional improvement in patients will be required in near future. PMID:27504360

    Full Text Available Background: The aim of this study was to determine the efficacy of two methods of colon preparation for colon cleansing in a randomized controlled trial. Methods: In this prospective randomized investigator-blinded trial, consecutive outpatients indicated for elective colonoscopy were randomized into two groups. Patients in Senna group took 24 tablets of 11 mg Senna in two divided doses 24 hour before colonoscopy. In Poly Ethylene Glycol (PEG group they solved 4 sachets in 4 liters of water the day before the procedure and were asked to drink 250 ml every 15 minutes. The overall quality of colon cleansing was evaluated using the Aronchick scoring scale. Difficulty of the procedure, patients′ tolerance and compliance and adverse events were also evaluated. Results: 322 patients were enrolled in the study. There was no significant difference in the quality of colon cleansing, patients′ tolerance, compliance and the difficulty of the procedure between two groups (p > 0.05. The incidence of adverse effects was similar between two groups except for abdominal pain that was more severe in Senna group (p < 0.05 and nausea and vomiting that was more common in PEG group (p < 0.05 Conclusions: In conclusion we deduce that Senna has the same efficacy and patient′s acceptance as Polyethylene glycol-electrolyte solution (PEG-ES and it could be prescribed as an alternative method for bowel preparation.

    Randomized clinical prospective study to evaluate the application of MTA and IRM as retrograde sealers in surgical endodontics. One hundred single-rooted teeth were surgically treated. After randomization, MTA or IRM was used as a retrosealer. Radiographs were taken 1 week, 3 months, and 1 year postoperatively. Assessment was performed by 2 independent assessors 1 year after surgery. Both treatment groups were homogeneous in their composition, and clinical features and radiographic findings were classified according to Rud's classification. Complete healing was observed in 64% of the MTA-treated teeth vs 50% of the IRM-treated teeth. Incomplete healing was seen in 28% (MTA) vs 36% (IRM), and unsatisfactory in 6% (MTA) vs 14% (IRM). Only 1 failure was seen (MTA). No statistically significant differences were found between the 2 retrofilling materials. As root-end filling materials in this clinical prospective randomized design on single rooted teeth, MTA and IRM had the same clinical effectiveness.

    Background Video-assisted thoracic surgery (VATS) has been shown to effectively reduce postoperative pain, enhance mobilization of the patients, shorten in-hospital length of stay, and minimize postoperative morbidity rates. The aim of this prospective study is to evaluate neuroendocrine and respiratory parameters as stress markers in cancer patients who underwent lung wedge resections, using both mini muscle-sparing thoracotomy and VATS approach. Methods The patients were randomly allocated into two groups: Group A (n=30) involved patients who were operated on using the VATS approach, while in group B (n=30), the mini muscle-sparing thoracotomy approach was used. Neuroendocrine and biological variables assessed included blood glucose levels, C-reactive protein (CRP) levels, cortisol, epinephrine, and adrenocorticotropic hormone (ACTH) levels. Arterial oxygen (PaO2) and carbon dioxide (PaCO2) partial pressure were also evaluated. All parameters were measured at the following time points: 24 hours preoperatively (T1), 4 hours (T2), 24 hours (T3), 48 hours (T4), and 72 hours (T5), after the procedure. Results PaO2 levels were significantly higher 4 and 24 hours postoperatively in group A vs group B, respectively (T2: 94.3 vs 77.9 mmHg, P=0.015, T3: 96.4 vs 88.7 mmHg, P=0.034). Blood glucose (T2: 148 vs 163 mg/dL, P=0.045, T3: 133 vs 159 mg/dL, P=0.009) and CRP values (T2: 1.6 vs 2.5 mg/dL, P=0.024, T3: 1.5 vs 2.1 mg/dL, P=0.044) were found increased in both groups 4 and 24 hours after the procedure. However, their levels were significantly lower in the VATS group of patients. ACTH and cortisol values were elevated immediately after the operation and became normal after 48 hours in both groups, without significant difference. Postoperative epinephrine levels measured in group A vs group B, respectively, (T2: 78.9 vs 115.6 ng/L, P=0.007, T3: 83.4 vs 122.5 ng/L, P=0.012, T4: 67.4 vs 102.6 ng/L, P=0.021). The levels were significantly higher in group B. Conclusion This

    To prospectively evaluate the safety of postoperative fondaparinux in comparison with low molecular weight heparin in patients undergoing uro-oncological surgery. The present study was a prospective, single-blind, non-inferiority randomized trial. A total of 359 patients undergoing surgery for urological malignancy were enrolled from January 2011 to December 2012. A total of 298 of these patients (fondaparinux group, 152; low molecular weight heparin group, 146) were evaluable for the intention-to-treat-analysis. Patients were randomly assigned to low-dose unfractionated heparin, 5000 units twice daily until postoperative day 1 plus either fondaparinux 2.5 mg once daily or low molecular weight heparin 2000 units twice daily until postoperative day 5. The primary end-point was postoperative bleeding as by independent review, and the study was powered to show the non-inferiority of fondaparinux versus low molecular weight heparin. The other adverse events were evaluated. D-dimer and soluble fibrin monomer complex levels were measured perioperatively. Bleeding occurred in 21 patients (12 in the fondaparinux group and 9 in low molecular weight heparin group, respectively). No significant differences were detected in the incidence of postoperative bleeding and the other adverse events between the two groups. The D-dimer was elevated on postoperative day 1 in one patient (16.6 μg/mL). In another patient, the soluble fibrin monomer complex was elevated (109 μg/mL). Fondaparinux is non-inferior to low molecular weight heparin with respect to risk of bleeding. The favorable safety profile of fondparinux supports its prophylactic use as an alternative to low molecular weight heparin after surgery for urological malignancy. © 2016 The Japanese Urological Association.

    We hypothesized that Benzocaine (Hurricaine) would work as quickly and effectively as viscous Lidocaine in this preparation. This was a prospective randomized, single-blinded comparison between Benzocaine and Lidocaine as the topical anesthetic in a gastrointestinal (GI) cocktail. Patients 18 years or older were approached for participation when a GI cocktail was ordered by the Emergency Physician. Patients were randomized to equivalent doses of either Benzocaine or viscous Lidocaine in addition to 30 cc of Maalox and 10 cc of Donnatal. Assessment using a visual analog pain scale occurred at time intervals of 0, 5, 15, and 30 min. Eighty-two patients were enrolled (44 to Benzocaine, 38 to viscous Lidocaine), with each group having a statistically significant improvement in pain (p Benzocaine and viscous Lidocaine groups in terms of the relief of symptoms at each of the assessment times. There were no adverse outcomes in either group.

  2. Prospect evaluation as a function of numeracy and probability denominator.

    2015-05-01

    This study examines how numeracy and probability denominator (a direct-ratio probability, a relative frequency with denominator 100, a relative frequency with denominator 10,000) affect the evaluation of prospects in an expected-value based pricing task. We expected that numeracy would affect the results due to differences in the linearity of number perception and the susceptibility to denominator neglect with different probability formats. An analysis with functional measurement verified that participants integrated value and probability into an expected value. However, a significant interaction between numeracy and probability format and subsequent analyses of the parameters of cumulative prospect theory showed that the manipulation of probability denominator changed participants' psychophysical response to probability and value. Standard methods in decision research may thus confound people's genuine risk attitude with their numerical capacities and the probability format used. Copyright © 2015 Elsevier B.V.

    Full Text Available Objectives: To evaluate, by means of a prospective randomized study, the efficacy of cinacalcet in the forms of nephrolithiasis associated with primary hyperparathyroidism in both the hypercalcemic and normocalcemic variant. Materials and Methods: Ten patients suffering from active nephrolithiasis associated with primary hyperparathyroidism (4 hypercalcemics and 6 normocalcemics, equally divided between males and females, were randomly but not blindly addressed to treatment with potassium citrate and allopurinol, or to the same therapeutic regimen in combination with cinacalcet. The dosage of cinacalcet was optimized for each patient in order to obtain a reduction of parathyroid hormone (PTH within normal limits while enabling the maintenance of adequate calcemic values. All study participants were given the same diet based on a reduction in sodium intake, oxalate-rich foods and animal protein with standardized intake of calcium and an increase in hydration. After a follow up period of 10 months , cinacalcet was associated to standard therapy and diet in patients who were not taken it, conversely cinacalcet was withdrawn in the remaining patients who remained on standard therapeutic regimen and diet. Follow up was continued for a second period of observation of the same duration of the first. Results: At the end of the period of treatment with cinacalcet, for both variants of hyperparathyroidism, a statistically significant reduction in the overall number and in the diameter of renal stones was found. Conclusions: This prospective randomized study shows the effectiveness of cinacalcet used in combination with a diet with normalized calcium intake, in reducing the number and size of urinary stones in hypercalemic and normocalcemic forms of primary hyperparathyroidism.

    The aim of this study is to examine, by a prospective randomized controlled trial, the influence of liberal (LIB) vs restricted (RES) perioperative fluid administration on morbidity following pancreatectomy. Randomized controlled trials in patients undergoing major intra-abdominal surgery have challenged the historical use of LIB fluid administration, suggesting that a more restricted regimen may be associated with fewer postoperative complications. Patients scheduled to undergo pancreatic resection were consented for randomization to a LIB (n = 164) or RES (n = 166) perioperative fluid regimen. Sample size was designed with 80% power to decrease Grade 3 complications from 35% to 21%. Between July 2009 and July 2015, we randomized 330 patients undergoing pancreaticoduodenectomy (PD, n = 218), central (n = 16), or distal pancreatectomy (DP, n = 96). Patients were equally distributed for all demographic and intraoperative characteristics. Intraoperatively, LIB patients received crystalloid 12 mL/kg/h and RES patients 6 mL/kg/h. Cumulative crystalloid given (median, range, mL) days 0 to 3 was LIB: 12,252 (6600 to 21,365), RES 7808 (2700 to 16,274) P LIB and 27% of RES patients (P = 0.6). Median length of stay was 7 and 5 days for PD and DP, respectively, in both arms. In a high volume institution, major perioperative complications from pancreatic resection were not significantly influenced by fluid regimens that differed approximately 1.6-fold.

    Full Text Available CONTEXT AND OBJECTIVE: Sepsis and septic shock are very common conditions among critically ill patients that lead to multiple organ dysfunction syndrome (MODS and death. Our purpose was to investigate the efficacy of early administration of dexamethasone for patients with septic shock, with the aim of halting the progression towards MODS and death. DESIGN AND SETTING: Prospective, randomized, double-blind, single-center study, developed in a surgical intensive care unit at Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo. METHODS: The study involved 29 patients with septic shock. All eligible patients were prospectively randomized to receive either a dose of 0.2 mg/kg of dexamethasone (group D or placebo (group P, given three times at intervals of 36 hours. The patients were monitored over a seven-day period by means of the sequential organ failure assessment score. RESULTS: Patients treated with dexamethasone did not require vasopressor therapy for as much time over the seven-day period as did the placebo group (p = 0.043. Seven-day mortality was 67% in group P (10 out of 15 and 21% in group D (3 out of 14 (relative risk = 0.31, 95% confidence interval 0.11 to 0.88. Dexamethasone enhanced the effects of vasopressor drugs. CONCLUSIONS: Early treatment with dexamethasone reduced the seven-day mortality among septic shock patients and showed a trend towards reduction of 28-day mortality.

    Dental anxiety is usually seen in the pediatric patients. specially in the case of minor oral surgical procedures and exodontia, cooperation of the patients and their families with the dentist will lead to superior treatment outcomes. Pain control is important in dentistry. The aim of this randomized prospective clinical study is to compare the local anaesthetic and haemodynamic effects of 2% lidocaine (Group 1) and 3% mepivacaine (Group 2) in sedated pediatric patients undergoing primary tooth extraction. 60 pediatric patients undergoing sedation for elective primary tooth extraction was prospectively included in the study in a randomized fashion. Inclusion and exclusion criteria were assigned. Patients were given premedication via oral route. Local anesthesia was achieved before extraction(s). There were no significant differences between the groups in patient demographics, number of teeth extracted, duration of the operation and time from the end of the procedure to discharge (p ≥ 0.05). FLACC pain scale scores were not statistically significant between the groups, except at 20 minutes post-operatively when the score is significantly lower in Group 2 (p=0.029). Prevention of pain during dental procedures can nurture the relationship of the patient and dentist. Tooth extraction under sedation in pediatric patients could be safe with both local anesthetics.

    A stochastic joint inverse algorithm to analyze diverse geophysical and hydrologic data for a geothermal prospect is developed. The purpose is to improve prospect evaluation by finding an ensemble of hydrothermal flow models that are most consistent with multiple types of data sets. The staged approach combines Bayesian inference within a Markov Chain Monte Carlo (MCMC) global search algorithm. The method is highly flexible and capable of accommodating multiple and diverse datasets as a means to maximize the utility of all available data to understand system behavior. An initial application is made at a geothermal prospect located near Superstition Mountain in the western Salton Trough in California. Readily available data include three thermal gradient exploration boreholes, borehole resistivity logs, magnetotelluric and gravity geophysical surveys, surface heat flux measurements, and other nearby hydrologic and geologic information. Initial estimates of uncertainty in structural or parametric characteristics of the prospect are used to drive large numbers of simulations of hydrothermal fluid flow and related geophysical processes using random realizations of the conceptual geothermal system. Uncertainty in the results is represented within a ranked subset of model realizations that best match all available data within a specified norm or tolerance. Statistical (posterior) characteristics of these solutions reflect reductions in the perceived (prior) uncertainties. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LLNL-ABS-641792.

    Given that the rationale for empirical antifungal therapy in neutropenic children is limited and based on adult patient data, we performed a prospective, randomized, controlled trial that evaluated 110 neutropenic children with persistent fever. Those at high risk for invasive fungal infections (IFI) received caspofungin (Arm C) or liposomal amphotericinB (Arm B); those with a lower risk were randomized to receive Arm B, C, or no antifungal treatment (Arm A). Complete response to empirical antifungal therapy was achieved in 90/104 patients (86·5%): 48/56 at high risk (85·7%) [88·0% in Arm B; 83·9% in Arm C (P = 0·72)], and 42/48 at low risk (87·5%) [87·5% in control Arm A, 80·0% Arm B, 94·1% Arm C; (P = 0·41)]. None of the variables tested by multiple logistic regression analysis showed a significant effect on the probability to achieve complete response. IFI was diagnosed in nine patients (8·2%, 95% confidence interval, 3·8-15·0). This randomized controlled study showed that empirical antifungal therapy was of no advantage in terms of survival without fever and IFI in patients aged <18 years and defined with low risk of IFI. Higher risk patients, including those with relapsed cancer, appear to be the target for empirical antifungal therapy during protracted febrile neutropenia.

    For gastric cancer patients, surgical resection with en-bloc lymphadenectomy is the cornerstone of curative treatment. Open gastrectomy has long been the preferred surgical approach worldwide. However, this procedure is associated with considerable morbidity. Several meta-analyses have shown an advantage in short-term outcomes of laparoscopic gastrectomy compared to open procedures, with similar oncologic outcomes. However, it remains unclear whether the results of these Asian studies can be extrapolated to the Western population. In this trial from the Netherlands, patients with resectable gastric cancer will be randomized to laparoscopic or open gastrectomy. The study is a non-blinded, multicenter, prospectively randomized controlled superiority trial. Patients (≥18 years) with histologically proven, surgically resectable (cT1-4a, N0-3b, M0) gastric adenocarcinoma and European Clinical Oncology Group performance status 0, 1 or 2 are eligible to participate in the study after obtaining informed consent. Patients (n = 210) will be included in one of the ten participating Dutch centers and are randomized to either laparoscopic or open gastrectomy. The primary outcome is postoperative hospital stay (days). Secondary outcome parameters include postoperative morbidity and mortality, oncologic outcomes, readmissions, quality of life and cost-effectiveness. In this randomized controlled trial laparoscopic and open gastrectomy are compared in patients with resectable gastric cancer. It is expected that laparoscopic gastrectomy will result in a faster recovery of the patient and a shorter hospital stay. Secondly, it is expected that laparoscopic gastrectomy will be associated with a lower postoperative morbidity, less readmissions, higher cost-effectiveness, better postoperative quality of life, but with similar mortality and oncologic outcomes, compared to open gastrectomy. The study started on 1 December 2014. Inclusion and follow-up will take 3 and 5

    Modern computed tomography (CT) uses detector arrays consisting of large numbers of photodiodes with scintil- lator crystals. The number of pixels in the array can play an important role in system performance. Considerable research has been performed on signal detection in flat backgrounds under various conditions, but little has been done with complex, random backgrounds in CT; our work investigates in particular the effect of the number of detector elements on signal detection by a channelized Hotelling observer in a complex background. For this project, a simulated three-dimensional phantom is generated with its attenuation equal to that of water. The phantom contains a smaller central section with random variations to simulate random anatomical structures. Cone-beam projections of the phantom are acquired at different angles and used to calculate the covariance matrix of the raw projection data. Laguerre-Gauss channels are used to reduce the dimensionality of each 2D projection and hence the size of the covariance matrix, but the covariance is still a function of two projection angles. A strong cross-channel correlation is observed as a function of the difference between the angles. A signal with known location and size is used, and the performance of the observer is calculated from the channel outputs at multiple projection angles. A contrast-detail diagram is computed for different variables such as signal size, number of incident x-ray photons, pixel size, etc. At a fixed observer signal-to-noise ratio (SNR), the contrast required to detect a signal increases dramatically as the signal size decreases.

    We conducted a prospective randomized trial to assess hemoglobin (Hb) response to recombinant human erythropoietin (rhEPO) therapy after hematopoietic cell transplantation (HCT). Patients (N = 131) were randomized (1:1) between no treatment (control arm) or erythropoietin at 500 U/kg per week (EPO arm). Patients were also stratified into 3 cohorts: patients undergoing myeloablative HCT with rhEPO to start on day (D)28, patients given nonmyeloablative HCT (NMHCT) with rhEPO to start on D28, and patients also given NMHCT but with rhEPO to start on D0. The proportion of complete correctors (ie, Hb ≥13 g/dL) before D126 posttransplant was 8.1% in the control arm (median not reached) and 63.1% in the EPO arm (median, 90 days) (P < .001). Hb levels were higher and transfusion requirements decreased (P < .001) in the EPO arm, but not during the first month in the nonmyeloablative cohort starting rhEPO on D0. There was no difference in rates of thromboembolic events or other complications between the 2 arms. This is the first randomized trial to demonstrate that rhEPO therapy hastens erythroid recovery and decreases transfusion requirements when started one month after allogeneic HCT. There was no benefit to start rhEPO earlier after NMHCT.

    To determine if the pregnancy rates (PRs) in infertile women could be improved with fallopian sperm perfusion in comparison with IUI. Randomized prospective analysis. Academically affiliated infertility center. Consecutive patients undergoing controlled ovarian hyperstimulation (COH). After hCG administration, patients were randomized to either IUI or fallopian sperm perfusion. Pregnancy rates with the two treatment modalities. Of 240 COH cycles, those randomized to IUI included 44 clomiphene citrate (CC) (group I) and 76 gonadotropin (group III) cycles. Patients receiving fallopian sperm perfusion included 44 cycles of CC (group II) and 76 cycles of gonadotropin (group IV) treatment. The overall PRs per cycle (10.8% versus 10.8%) were similar for IUI and fallopian sperm perfusion, respectively. The PRs were also similar when compared for ovulation induction with CC (6.8% versus 9.1%) and gonadotropins (13.2% versus 11.8%). We conclude that fallopian sperm perfusion offers no advantage over IUI. Because the process of fallopian sperm perfusion is more time consuming and more costly (because of increased media usage), fallopian sperm perfusion does not seem indicated as a routine infertility therapy and should not replace IUI.

    Topical therapies are the first line of treatment for patients with stable plaque psoriasis (SPP) affecting a limited body surface area. Very few trials comparing newer agents, such as 0.005% topical calcipotriol, with conventional modes of therapy, such as coal tar ointment, have been reported. A prospective, right-left randomized, investigator-blinded study with a 12-week treatment period and an 8-week follow-up period was performed. It was found that 0.005% calcipotriol ointment produced a faster initial response and had better cosmetic acceptability in patients, although after a long period of treatment, i.e. 12 weeks, 5% coal tar ointment had comparable efficacy. There was no statistically significant difference in the relapse rates between the two modalities.

    STUDY DESIGN: A prospective randomized clinical study. OBJECTIVE: To compare 2 surgical methods in the treatment of cervical radiculopathy caused by hard or soft disc herniation; namely, simple discectomy versus discectomy with an additional interbody fusion with a Ray titanium cage. SUMMARY...... by fusion with a Ray titanium cage (40 patients) or to discectomy alone (46 patients). Clinical and radiologic follow-up was performed 3, 12, and 24 months after surgery. RESULTS: There was no statistically significant difference between the 2 groups concerning self-reported satisfaction or severity of pain...... in the neck and arm. Two years after the operation, 86.1% of the patients treated with cage stated a good outcome versus 76.7% in the discectomy group (P = 0.44). The rate of fusion was 83.3% in the cage group versus 81.0% in the discectomy group (P = 0.30). Furthermore, after 2 years, also the rates of new...

    Ninety infants and children were prospectively randomized to receive cefepime (n = 43) or cefotaxime (n = 47) for therapy of bacterial meningitis. The two treatment groups were comparable in terms of age, duration of illness before enrollment, history of seizures, clinical status on admission, and etiology. Six (7%) patients died--two treated with cefepime and four treated with cefotaxime. Clinical response, cerebrospinal fluid sterilization, development of complications, antibiotic toxicity, and hospital stay were similar for the two treatment regimens. Concentrations of cefepime in cerebrospinal fluid varied from 55 to 95 times greater than the maximal MIC required by the causative pathogens. Audiologic and/or neurologic sequelae were found in 16% of the cefepime-treated patients and 15% of the cefotaxime-treated patients examined 2 to 6 months after discharge. We conclude that cefepime is safe and therapeutically equivalent to cefotaxime for management of bacterial meningitis in infants and children.

    In a number of studies, centrifugal blood pumps--in comparison with roller pumps--have been shown to attenuate trauma to blood components. Nevertheless, the impact of these results on the postoperative course needs to be discussed controversially. In a prospective randomized study, 240 consecutive adult patients underwent elective myocardial revascularization with cardiopulmonary bypass employing five different pumps (Roller, Avecor, Sarns, Rotaflow, Bio-Medicus). We analyzed clinical course, blood loss, damage of blood components, and impairment of the hemostatic system. The study population was homogenous with respect to age, gender, myocardial function, and operative data. No differences were found with respect to time of ventilation, duration of intensive care stay, hospitalization, and laboratory data. The choice of arterial pump during standard extracorporeal bypass for elective coronary artery bypass grafting is no matter of concern.

  1. Conservative treatment, plate fixation, or prosthesis for proximal humeral fracture. A prospective randomized study

    Full Text Available Abstract Background Proximal humerus fracture is the third most common fracture type after hip and distal radius fracture in elderly patients. A comprehensive study by Palvanen et al. demonstrated an increase in the annual fracture rate of 13.7% per year over the past 33 years. Should this trend continue, the fracture rate would triple over the next three decades. The increasing incidence of low-energy fractures raises questions about the optimal treatment in terms of functional outcome, pain, and rehabilitation time, as well as the economical impact. Despite the high incidence and costs of proximal humerus fractures, there is currently no valid scientific evidence for the best treatment method. Several publications, including a Cochrane review outline the need for high-quality, well-designed randomized controlled trials. Methods/Design The study is a prospective, randomized, national multi-center trial. The hypothesis of the trial is that surgical treatment of displaced proximal humerus fractures achieves better functional outcome, pain relief, and patient satisfaction compared to conservative treatment. The trial is designed to compare conservative and surgical treatment of proximal humerus fractures in patients 60 years and older. The trial includes two strata. Stratum I compares surgical treatment with locking plates to conservative treatment for two-part fractures. Stratum II compares multi-fragmented fractures, including three- and four-part fractures. The aim of Stratum II is to compare conservative treatment, surgical treatment with the Philos locking plate, and hemiarthroplasty with an Epoca prosthesis. The primary outcome measure will be the Disabilities of the Arm, Shoulder and Hand (DASH score and the secondary outcome measures will be the EuroQol-5D (EQ-5D value, OSS, Constant-Murley Score, VAS, and 15D. Recruiting time will be 3 years. The results will be analyzed after the 2-year follow-up period. Discussion This publication

    The authors report the preliminary results of a prospective comparison of IPOM (group A) and "open tension free" (group B) hernioplasty in 50 patients having a mono or bilateral primitive hernia. In group A (26 patients) hernia repair was performed using "Gore-Tex DualMesh Plus biomaterial with holes Corduroy" and in group B (24 patients) using the patch and plug technique with Marlex prosthesis. No intraoperative complications occurred and, in group A, no conversion was necessary. Four minor complications were obser-ved in group A (10.8%): 3 seromas and 1 transient paresthesia; 5 in group B (16%): 4 hematomas and 1 wound infection (p=n.s.). In group A only 2 patients (7.6%) needed analgesics after the first 24 hours and 12 patients (50%) in group B (p<0.001). Mean resumption of normal activity was 8 days in group A and 17 days in group B (p<0.001). At a 12-month-follow-up, no recurrence was reported in both groups. The results of this prospective randomized study show that IPOM may be not only a feasible and effective procedure in the treatment of recurrent and bilateral hernia or when hernia repair is performed during other laparoscopic procedures, but also in particular cases of primitive hernia such as in very active young males or heavy duty workers. However it is necessary to definitely ascertain the true incidence of recurrence in non limited series and in longer follow-up and the preliminary results of this study encourage the authors to complete the randomized study.

    Full Text Available OBJECTIVE: The antiseptic effect of gastric irrigation before endoscopic submucosal dissection (ESD has not yet been reported. The aim of the randomized prospective study is to evaluate the antiseptic effects of gastric irrigation of saline solution before ESD by evaluating bacterial count. METHODS: This prospective randomized controlled trial included 50 patients diagnosed with early gastric cancer who were randomly divided into 2 groups (25 patients in each group by using the opaque envelope method: the clean group (irrigation with 2 L saline solution before ESD and the regular group (no irrigation. The gastric juice was collected and cultured before ESD. The entire stomach was irrigated using a water jet attached to an endoscope. After ESD with resection and removal of the tumor specimen, a postoperative culture of the gastric juice was obtained using the same method as the preoperative culture. RESULTS: The mean log bacterial count of the post-gastric irrigation gastric juice was 5.08±0.75 in the regular group and 1.86±0.86 in the clean group. The difference in the bacterial counts was significant between the groups (P = 0.0004. The difference in the white blood cells (WBC count on POD 1 was significant (P = 0.044. WBC count on POD 2 did not significantly differ between the groups (P = 0.3. The difference in the body temperature (BT on POD 1 was significant (P = 0.017, On POD 2 the BT was not significant between the groups (P = 0.5. On POD 1, 88% of the patients in the regular group and 16% of the patients in the clean group had mild to moderate spontaneous pain (P = 0.0026. On POD 2 the proportion with mild to moderate spontaneous pain was 36% and 24% in the regular group and the clean group, respectively (P = 0.1. CONCLUSION: Pre-ESD gastric irrigation with saline solution is effective and feasible for suppressing infection during the ESD procedure with favorable clinical outcomes. TRIAL REGISTRATION

    Full Text Available Purpose To evaluate the postoperative analgesic efficacy of penile block, caudal block and intravenous paracetamol administration following circumcision. Materials and Methods In this prospective randomized study a total of 159 patients underwent circumcision under general anesthesia at urology clinic of Ufuk University Faculty of Medicine and Sorgun State Hospital between May 2012 and September 2012. The patients were randomized to three groups to receive penile block (Group 1, caudal block (Group 2 and intravenous paracetamol administration (group 3. Pain measurement of the patients was done via CHEOPS scoring system at 30,60,120 and 180 minutes postoperatively and compared. Statistical tests were performed with a conventional statistics program and statistical significance was set at a p value of < 0.05. Results The mean age of the patients was 5.7 years. Patients in group 1 had significantly lower pain score at 30 minutes compared to other two groups. At 60 minutes groups 1 and 2 had significantly lower score compared to group 3. At 120 and 180 minutes no difference between the groups was observed. No significant major complications were observed in all 3 groups. Conclusion Penile block and caudal block provide similar pain scores and painless postoperative periods after circumcision under general anesthesia. Intravenous paracetamol is insufficient at the early postoperative period. The three procedures were shown to be safe for analgesia following circumcision.

    Prospective, randomized, pilot clinical study was conducted to evaluate the beneficial effects of inositol hexaphosphate (IP6) + Inositol in breast cancer patients treated with adjuvant therapy. Patients with invasive ductal breast cancer where polychemotherapy was indicated were monitored in the period from 2005-2007. Fourteen patients in the same stage of ductal invasive breast cancer were involved in the study, divided in two randomized groups. One group was subjected to take IP6 + Inositol while the other group was taking placebo. In both groups of patients the same laboratory parameters were monitored. When the treatment was finished, all patients have filled questionnaires QLQ C30 and QLQ-BR23 to determine the quality of life. Patients receiving chemotherapy, along with IP6 + Inositol did not have cytopenia, drop in leukocyte and platelet counts. Red blood cell counts and tumor markers were unaltered in both groups. However, patients who took IP6 + Inositol had significantly better quality of life (p = 0.05) and functional status (p = 0.0003) and were able to perform their daily activities. IP6 + Inositol as an adjunctive therapy is valuable help in ameliorating the side effects and preserving quality of life among the patients treated with chemotherapy.

    A double blind, prospective and randomized study was carried out in forty patients with clinical diagnosis of vernal conjunctivitis and eosinophilia in conjunctival scrapings. They were divided in two randomized groups of 20 patients each. One of the groups received levocabastine ophthalmic solution and the other saline solution drops. The mean age of the study group was 9.1 years old with a vernal conjunctivitis history of 44 months. The control group mean age was 10.1 years old and a history of vernal conjunctivitis of 48 months prior the enter of the study. One group received levocabastine 0.5 mgrs/ml while the other balanced saline solution, one drop every 12 hours per seven days. The patients evaluated their symptoms through a visual analogic scale (every day). Data collected was analyzed, for the first, third and seventh day, through U-Mann Whitney statistical analysis. Epiphora and photophobia showed a significant improvement. Itching, edema and foreign body sensation showed improvement in the levocabastine group but without statistical significance. Hyperthermia remained the same in both groups studied.

    Full Text Available Maize (Zea mays L. is the second important commodity after rice in Indonesia. As of  2015, more than 3 million tons of maize grain still need to be imported. It is caused by productivity of maize which remains low due to the lowness proportion of hybrid maize seed. In addition to a single cross, threeway cross seed is still necessary as alternatives for farmers rather than open pollinated cultivar ones. The purpose of this study was to evaluate grain yield of 11 prospective genotypes utilizing BISI 18 and Sukmaraga as control cultivars. Randomized block design (RBD with three replications was adopted. The study was carried out in the dry season 2015. The result of this study showed that at 95% confidence level (a=0.05, prospective genotype SSUSX48274 performed significantly better than BISI 18 and Sukmaraga, while others yielded significantly better than Sukmaraga, but equal to BISI 18. All new prospective genotypes could be included in the  multilocation trial in order to release superior varieties.

    From 2002 to 2011, there were more than 17,000 shootings in Philadelphia. "Turning Point," Temple University Hospital's inpatient violence intervention program, takes advantage of the teachable moment that occurs after violent injury. In addition to receiving traditional social work services, Turning Point patients watch their trauma bay resuscitation video and a movie about violence, meet with a gunshot wound survivor and an outpatient case manager, and also undergo psychiatric assessment. The purpose of this study was to determine the efficacy of Turning Point in changing attitudes toward guns and violence among victims of penetrating trauma. This prospective randomized study was conducted from January 2012 to January 2014. Patients who sustained a gunshot or stab wound were randomized to standard of care, which involved traditional social work services only, or Turning Point. The Attitudes Toward Guns and Violence Questionnaire was administered to assess attitude change. Analysis was performed with repeated-measures analysis of variance. A p violence. Turning Point is effective in changing attitudes toward guns and violence among victims of penetrating trauma. Longer follow-up is necessary to determine if this program can truly be a turning point in patients' lives. Therapeutic/care management study, level II.

    Tonsillectomy with or without adenoidectomy still is one of the most commonly performed surgical procedures in the world, mostly in the pediatric population. to study the impact of amoxicillin for 7 days in post-adenotonsillectomy recovery, comparing results with a control group. prospective, randomized, controlled study with 120 patients. the patients were randomized according to surgery time to receive 7 days of amoxicillin associated with pain killers, or analgesic alone. During the first week of postoperative, we assessed the level of pain, oral intake acceptance, nausea and vomits, fever and return to daily activities. It was only in the fourth post-operative day that the group receiving antibiotic agents showed a statistically significant difference as far as pain is concerned. There was no difference between the two groups for other data analyzed. considering the results from our study and reviewing the literature on the use of antibiotic agents, we agree that there is no improvement in patient recovery after adenotonsillectomy with the use of amoxicillin for 7 days in the postoperative.

    The objectives of this prospective randomized trial were to assess the impact of Peyton's four-step approach on the acquisition of complex psychomotor skills and to examine the influence of gender on learning outcomes. We randomly assigned 95 third to fifth year medical students to an intervention group which received instructions according to Peyton (PG) or a control group, which received conventional teaching (CG). Both groups attended four sessions on the principles of manual therapy and specific manipulative and diagnostic techniques for the spine. We assessed differences in theoretical knowledge (multiple choice (MC) exam) and practical skills (Objective Structured Practical Examination (OSPE)) with respect to type of intervention and gender. Participants took a second OSPE 6 months after completion of the course. There were no differences between groups with respect to the MC exam. Students in the PG group scored significantly higher in the OSPE. Gender had no additional impact. Results of the second OSPE showed a significant decline in competency regardless of gender and type of intervention. Peyton's approach is superior to standard instruction for teaching complex spinal manipulation skills regardless of gender. Skills retention was equally low for both techniques.

    Full Text Available Background. The use of a suction drain in thyroid surgery is common practice in order to avoid hematomas or seromas. The aim of this study was to determine the efficacy of routine drainage after thyroid surgery. Methods. In this prospective randomized trial, 400 patients who underwent either a total thyroidectomy or lobectomy for thyroid disorders were randomly allocated to either the nondrainage (group 1 or the drainage (group 2 group. The volume of fluid collection in the operative bed, postoperative pain, complications, and length of hospital stay were then recorded. Results. Both groups were homogeneous according to age, gender, thyroid volume, type of procedure performed, and histopathological diagnosis. After assessment by USG, no significant difference was found between the groups in the fluid collection of the thyroid bed (, but the length of hospital stay was significantly reduced in group 1 (. Conclusions. In our experience, the use of drain for thyroid surgery is not a routine procedure. However, it should be used in the presence of extensive dead space, particularly when there is retrosternal or intrathoracic extension, or when the patient is on anticoagulant treatment. This trial was registered with clinical Trials.gov NCT01771523.

    Acute alcohol withdrawal syndrome (AAWS) is encountered in patients presenting acutely to the Emergency Department (ED) and often requires pharmacologic management. We investigated whether a single dose of intravenous (i.v.) phenobarbital combined with a standardized lorazepam-based alcohol withdrawal protocol decreases intensive care unit (ICU) admission in ED patients with acute alcohol withdrawal. This was a prospective, randomized, double-blind, placebo-controlled study. Patients were randomized to receive either a single dose of i.v. phenobarbital (10 mg/kg in 100 mL normal saline) or placebo (100 mL normal saline). All patients were placed on the institutional symptom-guided lorazepam-based alcohol withdrawal protocol. The primary outcome was initial level of hospital admission (ICU vs. telemetry vs. floor ward). There were 198 patients enrolled in the study, and 102 met inclusion criteria for analysis. Fifty-one patients received phenobarbital and 51 received placebo. Baseline characteristics and severity were similar in both groups. Patients that received phenobarbital had fewer ICU admissions (8% vs. 25%, 95% confidence interval 4-32). There were no differences in adverse events. A single dose of i.v. phenobarbital combined with a symptom-guided lorazepam-based alcohol withdrawal protocol resulted in decreased ICU admission and did not cause increased adverse outcomes.

    A randomized, prospective study was designed to compare a continuous with an interrupted technique for closing an abdominal incision. Five hundred seventy-one patients were randomized between the closure methods and stratified as to type of wound: clean, clean-contaminated, or contaminated. In mid-line incisions, the dehiscence rate was 2.0% (5/244) for the continuous group versus 0.9% (2/229) for the interrupted group. The difference was not statistically significant. Ventral hernias formed in 2.0% (4/201) of the continuous group vs. 0.5% (1/184) of the interrupted group. The type of wound had no influence on the results. In oblique incisions, 0% (0/39) of wounds closed continuously dehised while 2% (1/50) of incisions closed interruptedly dehised. No ventral hernias formed. Further analysis of the data indicated that dehiscence was more likely related to improper surgical technique than to the method of closure. An abdominal incision could be closed with a continuous suture in approximately half the time required for placing interrupted sutures (20 vs. 40 minutes). A continuous closure is preferred because it is more expedient and because it has the same incidence of wound disruption compared with an interrupted closure. PMID:6297417

    2006-01-01

    Background: Prior study has shown that right paracolic adhesions are found in 90% of patients with chronic pelvic pain and less frequently in pain-free patients. We set out to determine whether paracolic adhesiolysis will reduce site-specific pain. Methods: This was a prospective, randomized trial of right paracolic adhesiolysis at the time of diagnostic and operative laparoscopy for chronic pelvic pain. Twenty-five patients with a diagnosis of chronic pelvic pain were randomized to either undergo or withhold lysis of right paracolic adhesions at the time of operative laparoscopy. Results: Right paracolic adhesions were found in 100% of our patients. For all subjects, there was a significant reduction of right and left lower quadrant pain (P<0.001) following the operative laparoscopy. Those who underwent right paracolic adhesiolysis had significantly greater right pelvic pain reduction than those who did not (P=0.014). There was no difference in the reduction of left or mid pelvic pain between the treatment and control groups. Conclusions: Right paracolic adhesiolysis reduces short-term site-specific tenderness in patients with chronic pelvic pain. Patients who would benefit from diagnostic or operative laparoscopy are likely to benefit further from paracolic adhesiolysis. PMID:17575754

    To compare bipolar with standard monopolar transurethral resection of the prostate (TURP). A prospectively randomized study was conducted between January 2010 and September 2011. Primary end points studied were efficacy (maximum flow rate [Qmax], International Prostate Symptom Score) and safety (adverse events, decline in postoperative serum sodium [Na+] and haemoglobin [Hb] levels). Secondary end points were operation time and duration of irrigation, catheterization, and hospitalization. Sixty consecutive patients were randomized and completed the study, with 29 patients in the monopolar TURP group and 31 in the TURIS group. At baseline, the two groups were comparable in age, prostate volume, mean prostate-specific antigen value, International Prostate Symptom Score, and they had at least 12 months of follow-up. Declines in the mean postoperative serum Na+ for bipolar and monopolar TURP groups were 1.2 and 8.7 mmol/L, respectively. However, there was no statistical difference in the decline in postoperative Hb between the two groups. The mean catheterization time was 26.6 and 52 hours in the bipolar and standard groups, respectively. This difference was statistically significant as was the difference in the time to hospital discharge. The IPSS and Qmax improvements were comparable between the two groups at 12 months of follow-up. No clinically relevant differences in short-term efficacy are existed between the two techniques, but bipolar TURP is preferable due to a more favorable safety profile and shorter catheterization duration.

    Improved laparoscopic experience and techniques have made laparoscopic cholecystectomy (LC) feasible options in cirrhotic patients. This study was designed to compare the risk and benefits of open cholecystectomy (OC) versus LC in compensated cirrhosis. A randomized prospective study, in the period from October 2002 till December 2006, where 110 cirrhotic patients with symptomatic gallstone were randomly divided into OC group (55 patients) and LC group (55 patients). There was no operative mortality. In LC group 4 (7.33%) patients were converted to OC. Mean surgical time was significantly longer in OC group than LC group (96.13+17.35 min versus 76.13+15.12) P<0.05, associated with significantly higher intraoperative bleeding in OC group (P<0.01), necessitating blood transfusions to 7 (12.72%) patients in OC group. The time to resume diet was 18.36+8.18 h in LC group which is significantly earlier than in OC group 47.84+14.6h P<0.005. Hospital stay was significantly longer in OC group than LC group (6+1.74 days versus 1.87+1.11 days) P<0.01 with low postoperative morbidity. LC in cirrhotics is still complicated and highly difficult which associates with significant morbidity compared with that of patients without cirrhosis. However, it offers lower morbidity, shorter operative time; early resume dieting with less need for blood transfusion and reducing hospital stay than OC.

    Full Text Available Background: The aim of this study was to prospectively compare single-dose intravenous antibiotic prophylaxis vs. no prophylaxis before minor cystoscopic procedures, including punch biopsy and transurethral resection (TUR of small bladder tumors. Materials and Methods: A total of 200 patients with a mean age of 47.3 years old (range: 19-84 years old with initial negative urine cultures were recruited. All patients underwent a diagnostic cystoscopy. Patients were then randomized into 2 groups: o0 ne group that did not receive antibiotics (100 patients and the other group that received antibiotic treatment (100 patients with a single intravenous dose of cefoperazone. All patients had urine analysis and urine cultures on the second day after the operation. Additionally, clinical parameters including fever and dysuria were recorded. In 15% of the patients, incidental additional interventions such as punch biopsy or TUR of a small bladder tumor that were similarly distributed in both groups were performed. Results: In 1 patient from the antibiotic group and 2 patients from the no prophylaxis group, the urine cultures after cystoscopy were positive. No statistically significant difference was observed between these groups based on the microbiological and clinical parameters. Conclusion: The current study provides evidence that no antibiotic prophylaxis is required before diagnostic cystoscopy in patients without bacteriuria. But, the absolute risk of infection was small, suggesting that a much larger study is required.

    The efficacy of irrigating the peritoneal cavity during appendectomy for perforated appendicitis has been debated extensively. To date, prospective comparative data are lacking. Therefore, we conducted a prospective, randomized trial comparing peritoneal irrigation to suction alone during laparoscopic appendectomy in children. Children younger than 18 years with perforated appendicitis were randomized to peritoneal irrigation with a minimum of 500 mL normal saline, or suction only during laparoscopic appendectomy. Perforation was defined as a hole in the appendix or fecalith in the abdomen. The primary outcome variable was postoperative abscess. Using a power of 0.8 and alpha of 0.05, a sample size of 220 patients was calculated. A battery-powered laparoscopic suction/irrigator was used in all cases. Pre- and postoperative management was controlled. Data were analyzed on an intention-to-treat basis. A total of 220 patients were enrolled between December 2008 and July 2011. There were no differences in patient characteristics at presentation. There was no difference in abscess rate, which was 19.1% with suction only and 18.3% with irrigation (P = 1.0). Duration of hospitalization was 5.5 ± 3.0 with suction only and 5.4 ± 2.7 days with group (P = 0.93). Mean hospital charges was $48.1K in both groups (P = 0.97). Mean operative time was 38.7 ± 14.9 minutes with suction only and 42.8 ± 16.7 minutes with irrigation (P = 0.056). Irrigation was felt to be necessary in one case (0.9%) randomized to suction only. In the patients who developed an abscess, there was no difference in duration of hospitalization, days of intravenous antibiotics, duration of home health care, or abscess-related charges. There is no advantage to irrigation of the peritoneal cavity over suction alone during laparoscopic appendectomy for perforated appendicitis. The study was registered with clinicaltrials.gov at the inception of enrollment (NCT00981136).

    We propose a new cryptographic scheme based on the Lorenz chaos attractor and 32 bit bent Boolean function. We evaluated the keystream generated by the scheme with batteries of the NIST statistical tests. We also applied a number of statistical analysis techniques, such as calculating histograms, correlations between two adjacent pixels, information entropy, and differential resistance, all refer to images encrypted by the proposed system. The results of the analysis show that the new cryptographic scheme ensures a secure way for sending digital data with potential applications in real-time image encryption.

The explanation of peptic ulcer etiology has changed significantly in the past decade after the clarification of the significance of Helicobacter pylori infection.Aim. To evaluate the effectiveness of Helicobacter pylori eradication in patients with hemorrhaging peptic ulcer and patients with peptic ulcer without complications.Study ethics. The study was approved in 1998 by the Medical Ethics Committee of the Republic of Slovenia (No. 90/09/98.Type of study. Prospective, controlled and randomized study, carried out between 1998–2000.Patients and methods. The study included 80 patients (50 male and 30 female, av.age 57.5 years, SD ± 17.1, range 22– 80 in which endoscopy confirmed hemorrhage from peptic ulcer of stomach or duodenum and Helicobacter pylori infection. In all cases endoscopic hemostasis was performed: injection sclerotherapy with diluted adrenalin 1:10,000 and 1% polidocanol or argon plasma coagulation. The control group was made up of 80 patients (50 male and 30 female, av.age 56.8 years, SD ± 16.8, range 19–80 with peptic ulcer of stomach or duodenum and Helicobacter pylori infection. Infection was confirmed by a rapid urease test and histologic investigation of the gastric mucosa. In all cases the recommended drug combinations were used in the treatment of the infection: a proton pump inhibitor, omeprazol (4 weeks, and combination of antibiotics, claritromycin and metronidazole or with regard to the antibiogram (1 week. The therapeutic success was ascertained endoscopically four weeks after inclusion in the study. Infection eradication was confirmed by the rapid urease test and histologic investigation of the gastric mucosa.Results. Four weeks after inclusion in the study the success of infection eradication was 92.5% in the study group, in the control group it was 91.3% (p > 0.05.

    The aim of this study was to compare the audiologic outcomes of the patients who underwent endoscopy on one ear and microscopic tympanoplasty on the other, and to investigate the operative time, graft success, postoperative pain and health status. This prospective randomized controlled study was carried out in Ege University ENT Department between February 2015 and September 2016. The patients who had bilateral chronic otitis media, normal middle ear mucosa and a hearing loss difference of 10 dB or less between the two ears randomly underwent microscopic tympanoplasty in one ear and endoscopic tympanoplasty in the contralateral ear, with 6-month intervals. 13 patients were included in the study with a mean age of 36.17 ± 3.61 years (range 17-53 years, 7 female, 6 male). The improvement in air-bone gap for groups 1 (endoscopic) and 2 (microscopic) was 9.48 ± 5.23 and 9.89 ± 2.79 dB, respectively. The duration of the surgery in group 1 was significantly lower than that in group 2 (p microscopic surgery. In addition, endoscopic surgery offers comparable improvement in air-bone gap and similar graft success. The endoscopic approach has comparable audiological and morphological graft outcomes with the microscopic one. The endoscopic approach yielded better health and pain status for the same patients. Level of evidence This is an individual randomized controlled trial. The level of evidence is 1b.

    Autologous blood transfusion from the placenta to the neonate at birth has been proven beneficial. Transfusion can be accomplished by either delayed cord clamping or cord stripping. Both are equally effective in previous randomized trials. We hypothesized that combining these 2 techniques would further improve outcomes in preterm neonates. This was a prospective randomized trial for singleton deliveries with estimated gestational ages between 22 and 31 6/7 weeks. The control protocol required a 30-second delayed cord clamping, whereas the test protocol instructed a concurrent cord stripping during the delay. The primary outcome was initial fetal hematocrit. We also examined secondary outcomes of neonatal mortality, length of time on the ventilator, days to discharge, peak bilirubin, number of phototherapy days, and neonatal complication rates. Of the 67 patients analyzed, 32 were randomized to the control arm and 35 were randomized to the test arm. The gestational ages and fetal weights were similar between the arms. Mean hematocrit of the control arm was 47.75%, and the mean hematocrit for the test arm was 47.71% (P = .98). These results were stratified by gestational age, revealing the infants less than 28 weeks had an average hematocrit of 41.2% in the control arm and 44.7% in the test arm (P = .12). In the infants with gestational ages of 28 weeks or longer, the control arm had an average hematocrit of 52.9%, which was higher than the test arm, which averaged 49.5% (P = .04). The control arm received an average of 1.53 blood transfusions, whereas the test arm received 0.97 (P = .33). The control arm had 3 neonatal deaths, and the test arm had none (P = .10). The average number of days until discharge was 71.2 for the control arm and 67.8 for the test arm (P = .66). The average number of days on the ventilator was 4.86 for the control arm and 3.06 for the test arm (P = .34). Adding cord stripping to the delayed cord clamp does not result in an increased

    OBJECTIVES To evaluate, in a pilot prospective randomized trial, the safety, effectiveness and radiological recurrence of retroperitoneal renal cyst decortication compared with retroperitoneal decortication with wadding using perirenal pedicled fat tissue. PATIENTS AND METHODS From March 2004 to December 2007, 40 patients with simple renal cysts were enrolled and randomized; 22 (group A) had a simple retroperitoneal decortication (SRD) and 18 (group B) a decortication with wadding of the cyst using perirenal fat tissue (RDCW). The following variables were recorded: age, gender, side, size on ultrasonography/computed tomography (CT), location, operative duration, blood loss, complications, pathology, presence or absence of flank pain, hypertension, urinary tract compression or urinary infection. The primary endpoint of this trial was to evaluate and compare the efficacy of both treatments. Secondary endpoints were safety and pain, hypertension and the resolution of urinary tract obstruction. RESULTS In all, 40 cysts were treated; there were no bilateral cysts. The mean (sd) size on CT was 11.9 (1.84) cm in group A and 12.8 (1.25) cm in group B (P = 0.1). All the procedures were completed laparoscopically and no conversion was necessary. There were no intraoperative complications. The mean (range) hospital stay was 3.4 (3-6) days. There was no statistically significant difference between the groups for all variables assessed. There was a radiological recurrence in three patients (14%) in group A, but none in group B (all successful). CONCLUSION To be completely successful, with maximum safety and to prevent recurrences in the treatment of renal cysts, RCDW is recommended when a retroperitoneal approach is chosen, especially if the cyst is located anteriorly. When symptom relief is considered, RCDW duplicates the results obtained with SRD.

    Patients surgically treated for infection after extremity fractures are typically discharged with a 6- to 12-week antibiotic regimen. Intravenous (IV) antibiotics are associated with significant cost and potential complications of deep vein thrombosis, line clotting, and sepsis. Many of the pathogens that cause musculoskeletal infection have both oral (PO) and IV antibiotic options with adequate bioavailability and antibacterial effect, yet IV antibiotics remain the standard of care absent evidence that PO options are clinically as efficacious. The POvIV study is a prospective, multicenter, randomized trial to compare PO with IV antibiotic therapy in patients with postoperative wound infections after extremity fractures. Patients between the ages of 18 and 84 who have a culture-positive surgical site infection after internal fixation for fracture repair or arthrodesis are approached for this study, and if they provide consent, are randomly assigned to receive either PO or IV antibiotics. Antibiotic selection is based on culture and sensitivity results. Randomization determines the route of administration. Patients are followed for 1 year after study enrollment. This study will be the largest prospective randomized trial to evaluate the safety and effectiveness of PO antibiotic use for treatment of postoperative wound infections. Results will inform clinician decisions on antibiotic delivery in patients with postoperative wound infections.

    Full Text Available The aim of this study was to evaluate the new version of Iranian EFL junior high school textbook (Prospect1 from the teachers’ perspectives. The participants included90experienced English teachers (42 females and 48 males randomly selected from different junior high schools in different districts of Gilan province, Iran. The evaluation of the textbook was conducted quantitatively through a 5-point Likert scale with seven criteria including subject and content, activities, skills, physical layout, practical consideration, language and general criteria. However, it was accompanied by some open-ended questions that solicited teachers' views about each criterion and the book in general. The descriptive statistics including standard deviation, mean, percentage and frequency were used in the data analysis.The findings revealed that teachers have positive perceptions toward this book.They had a positive view about the prospect1 because of its content and topic relevancy to learners' needs, including real life situations, enjoying challenging subject, having communicative pair and group works and attending to four skills equally. However, they intensified some problems in their open ended questions such as insufficiency of teaching time that is 1.5 hour during a week, not focusing on explicit presentation of some words and grammatical points and not paying attention to some sub-skill strategies. These findings can be helpful for curriculum designers and textbook writers to design some valuable textbooks for other levels and to consider correspondence between time of teaching and volume of the book.

    Friction foot blisters are a common injury occurring in up to 39% of marathoners, the most common injury in adventure racing, and represent more than 70% of medical visits in multi-stage ultramarathons. The goal of the study was to determine whether paper tape could prevent foot blisters in ultramarathon runners. This prospective randomized trial was undertaken during RacingThePlanet 155-mile (250-km), 7-day self-supported ultramarathons in China, Australia, Egypt, Chile, and Nepal in 2010 and 2011. Paper tape was applied prerace to one randomly selected foot, with the untreated foot acting as the own control. The study end point was development of a hot spot or blister on any location of either foot. One hundred thirty-six participants were enrolled with 90 (66%) having completed data for analysis. There were 36% women, with a mean age of 40 ± 9.4 years (range, 25-40 years) and pack weight of 11 ± 1.8 kg (range, 8-16 kg). All participants developed blisters, with 89% occurring by day 2 and 59% located on the toes. No protective effect was observed by the intervention (47 versus 35; 52% versus 39%; P = .22), with fewer blisters occurring around the tape on the experimental foot than under the tape (23 vs 31; 25.6% versus 34.4%), yet 84% of study participants when queried would choose paper tape for blister prevention in the future. Although paper tape was not found to be significantly protective against blisters, the intervention was well tolerated with high user satisfaction. Copyright © 2014 Wilderness Medical Society.

    We assessed the short-term effects of hypertonic fluid versus isotonic fluid administration in patients with septic shock. This was a double-blind, prospective randomized controlled trial in a 15-bed intensive care unit. Twenty-four patients with septic shock were randomized to receive 250 mL 7.2% NaCl/6% hydroxyethyl starch (HT group) or 500 mL 6% hydroxyethyl starch (IT group). Hemodynamic measurements included mean arterial blood pressure (MAP), central venous pressure, stroke volume index, stroke volume variation, intrathoracic blood volume index, gastric tonometry, and sublingual microcirculatory flow as assessed by sidestream dark field imaging. Systolic tissue Doppler imaging velocities of the medial mitral annulus were measured using echocardiography to assess left ventricular contractility. Log transformation of the ratio MAP divided by the norepinephrine infusion rate (log MAP/NE) quantified the combined effect on both parameters. Compared with the IT group, hypertonic solution treatment resulted in an improvement in log MAP/NE (P = 0.008), as well as an increase in systolic tissue Doppler imaging velocities (P = 0.03) and stroke volume index (P = 0.017). No differences between the groups were found for preload parameters (central venous pressure, stroke volume variation, intrathoracic blood volume index) or for afterload parameters (systemic vascular resistance index, MAP). Hypertonic solution treatment decreased the need for ongoing fluid resuscitation (P = 0.046). No differences between groups were observed regarding tonometry or the sublingual microvascular variables. In patients with septic shock, hypertonic fluid administration did not promote gastrointestinal mucosal perfusion or sublingual microcirculatory blood flow in comparison to isotonic fluid. Independent of changes in preload or afterload, hypertonic fluid administration improved the cardiac contractility and vascular tone compared with isotonic fluid. The need for ongoing fluid

    Surgical site infection is a common complication following cardiac surgery. Triclosan-coated sutures have been shown to reduce the rate of infections in various surgical wounds, including wounds after vein harvesting in coronary artery bypass grafting patients. Our purpose was to compare the rate of infections in sternotomy wounds closed with triclosan-coated or conventional sutures. A total of 357 patients that underwent coronary artery bypass grafting were included in a prospective randomized double-blind single-center study. The patients were randomized to closure of the sternal wound with either triclosan-coated sutures (Vicryl Plus and Monocryl Plus, Ethicon, Inc., Somerville, NJ, USA) (n = 179) or identical sutures without triclosan (n = 178). Patients were followed up after 30 days (clinical visit) and 60 days (telephone interview). The primary endpoint was the prevalence of sternal wound infection according to the Centers for Disease Control and Prevention (CDC) criteria. The demographics in both groups were comparable, including age, gender, body mass index, and rate of diabetes and smoking. Sternal wound infection was diagnosed in 43 patients; 23 (12.8%) sutured with triclosan-coated sutures compared to 20 (11.2%) sutured without triclosan (p = 0.640). Most infections were superficial (n = 36, 10.1%), while 7 (2.0%) were deep sternal wound infections. There were 16 positive cultures in the triclosan group and 17 in the non-coated suture group (p = 0.842). The most commonly identified main pathogens were Staphylococcus aureus (45.4%) and coagulase-negative staphylococci (36.4%). Skin closure with triclosan-coated sutures did not reduce the rate of sternal wound infection after coronary artery bypass grafting. (clinicaltrials.gov: NCT01212315).

    Rupture of the Achilles tendon is a common injury during working years. Aggressive rehabilitation may provide better outcomes, but also a greater chance of re-rupture. To determine if aggressive rehabilitation has better clinical outcomes for Achilles tendon function, Triceps surae function, one-leg heel rise capacity and lower complication rate during twelve weeks after percutaneous Achilles tendon repair compared to conventional rehabilitation. Randomized controlled trial. Thirty-nine patients were prospectively randomized. The aggressive group (n=20, 41.4 ± 8.3 years) received rehabilitation from the first day after surgery. The conventional group (n=19, 41.7 ± 10.7 years) rested for 28 days, before rehabilitation started. The statistical parameters were the Achilles tendon rupture score (ATRS), verbal pain scale, time to return to work, pain medication consumption, Achilles tendon strength, dorsiflexion range of motion (RoM), injured-leg calf circumference, calf circumference difference, one-leg heel rise repetition and difference, re-rupture rate, strength deficit rate, and other complication rates. Mixed-ANOVA and Bonferroni's post hoc test were performed for multiple comparisons. Student's t-test was performed for parameters measured on the 12th week. The aggressive group with respect to the conventional group had a higher ATRS; lower verbal pain score; lower pain medication consumption; early return to work; higher Achilles tendon strength; higher one-leg heel rise repetitions; and lower one-leg heel rise difference. The re-rupture rate was 5% and 5%, the strength deficit rate was 42% and 5%, and other complications rate was 11% and 15% in the conventional and aggressive group, respectively. Patients with Dresden repair and aggressive rehabilitation have better clinical outcomes, Achilles tendon function and one-leg heel rise capacity without increasing the postoperative complications rate after 12 weeks compared to rehabilitation with immobilization and

    Full Text Available Abstract Background The large clinical trials proved that Basal-Bolus (BB insulin therapy was effective in the prevention of diabetic complications and their progression. However, BB therapy needs multiple insulin injections per a day. In this regard, a biphasic insulin analogue needs only twice-daily injections, and is able to correct postprandial hyperglycemia. Therefore it may achieve the blood glucose control as same as that of BB therapy and prevent the diabetic complications including macroangiopathy. Methods In PROBE (Prospective, Randomized, Open, Blinded-Endpoint design, forty-two type 2 diabetic patients (male: 73.8%, median(inter quartile range age: 64.5(56.8~71.0years with secondary failure of sulfonylurea (SU were randomly assigned to BB therapy with a thrice-daily insulin aspart and once-daily basal insulin (BB group or to conventional therapy with a twice-daily biphasic insulin analogue (30 Mix group, and were followed up for 6 months to compare changes in HbA1c, daily glycemic profile, intima-media thickness (IMT of carotid artery, adiponectin levels, amounts of insulin used, and QOL between the two groups. Results After 6 months, HbA1c was significantly reduced in both groups compared to baseline (30 Mix; 9.3(8.1~11.3 → 7.4(6.9~8.7%, p Conclusion Both BB and 30 mix group produced comparable reductions in HbA1c in type 2 diabetic patients with secondary failure. There was no significant change in IMT as an indicator of early atherosclerotic changes between the two groups. The basal-bolus insulin therapy may not be necessarily needed if the type 2 diabetic patients have become secondary failure. Trial registration Current Controlled Trials number, NCT00348231

    Background Cilostazol is a newly developed antiplatelet drug that has been widely applied for clinical use. Its antiplatelet action appears to be mainly related to inhibition of intracellular phosphodiesterase activity. Recently,cilostazol has been used for antiplatelet therapy after coronary bare metal stent implantation for thrombosis and restenosis prevention. This prospective randomized and double blind trial was designed to investigate the safety and efficacy of cilostazol for the prevention of late restenosis and acute or subacute stent thrombosis.Methods One hundred and twenty patients who underwent elective stent were randomly assigned to treatment group with cilostazol 200 mg/d (n = 60), clopidogrel 75 mg/d and aspirin 100 mg/d or to control group with clopidogrel treatment 75 mg/d (n = 60) and aspirin 100 mg/d. Follow-up coronary angiography was performed 6-9 months later.Results Nine months major adverse cardio-cerebral event (MACCE) were lower in treatment groups (P<0.05).The quantitative coronary angiography (QCA) at 6 months follow-up showed that minimum lumen diameter(MLD) was higher in treatment group than that of control group [(2.14±0.52)mm vs (1.82 ±0.36)mm, P<0.05].Late lumen loss (LL) [(0.82 ± 0.42)mm vs (1.31 ± 0.58)mm; P<0.01 ], restenosis rate (RR) (14% vs 32%; P<0.05)and target lesion revascularizaion (TLR) rate (5% vs 17%; P<0.05) were lower in treatment group than in control group.Conclusion Cilostazol therapy is an effective regimen for prevention not only stent thrombosis but also RR and TLR through reducing MLD without the risk of increasing bleeding.

    Induction therapy with alemtuzumab followed by lower maintenance immunosuppression (IS) has been associated with reduced morbidity and mortality in abdominal and heart transplantation (TX). In the current study, alemtuzumab, in combination with reduced levels of maintenance IS, was compared to thymoglobulin in combination with standard IS. Sixty consecutive patients who underwent lung transplantation (LUTX) at a single center were prospectively randomized in two groups: group A received alemtuzumab in conjunction with reduced doses of tacrolimus, steroids and mycophenolate mofetil. Group B received thymoglobulin in association with standard dose IS. Patient and graft survival, freedom from acute cellular rejection (ACR), lymphocytic bronchiolitis, bronchiolitis obliterans syndrome, kidney function, infectious complications and posttransplant lymphoproliferative disorder were analyzed. Alemtuzumab induction therapy resulted in complete the absence of ACR episodes ≥ A2 within the first year post-TX. The difference to thymoglobulin was significant (alemtuzumab 0 vs. ATG 0.33; p = 0.019). All other factors studied did not show any differences between the two groups. Alemtuzumab induction therapy after LUTX in combination with reduced maintenance IS significantly reduces higher-grade rejection rates. This novel therapeutic agent had no impact on survival, infections rates, kidney function and incidence of malignancies.

    Full Text Available Abstract Background Breast cancer risk education enables women make informed decisions regarding their options for screening and risk reduction. We aimed to determine whether patient education regarding breast cancer risk using a bar graph, with or without a frequency format diagram, improved the accuracy of risk perception. Methods We conducted a prospective, randomized trial among women at increased risk for breast cancer. The main outcome measurement was patients' estimation of their breast cancer risk before and after education with a bar graph (BG group or bar graph plus a frequency format diagram (BG+FF group, which was assessed by previsit and postvisit questionnaires. Results Of 150 women in the study, 74 were assigned to the BG group and 76 to the BG+FF group. Overall, 72% of women overestimated their risk of breast cancer. The improvement in accuracy of risk perception from the previsit to the postvisit questionnaire (BG group, 19% to 61%; BG+FF group, 13% to 67% was not significantly different between the 2 groups (P = .10. Among women who inaccurately perceived very high risk (≥ 50% risk, inaccurate risk perception decreased significantly in the BG+FF group (22% to 3% compared with the BG group (28% to 19% (P = .004. Conclusion Breast cancer risk communication using a bar graph plus a frequency format diagram can improve the short-term accuracy of risk perception among women perceiving inaccurately high risk.

    The aim of this study was to compare the reduction of spinal cord compression after surgical treatment of dogs with acute thoracolumbar intervertebral disc (IVD) extrusion achieved using hemilaminectomy versus mini-hemilaminectomy techniques. This was a prospective randomized study with client-owned dogs presented with acute IVD extrusion that were allocated to surgical treatment using hemilaminectomy (n = 15) or mini-hemilaminectomy (n = 15) techniques. Plain and intravenous-contrast computed tomography was performed pre- and postoperatively. The preoperative minimal cross-sectional dimension of the spinal cord (MDSCpre) and the postoperative minimal cross-sectional dimension of the spinal cord (MDSCpost) were measured at the level of greatest compression. The minimal diameter of the uncompressed spinal cord was measured in a similar way both pre- (MDUSCpre) and postoperatively (MDUSCpost). Dogs in the mini-hemilaminectomy group had significantly greater reduction of compression (RC) (p < 0.01) after surgery compared to dogs in the hemilaminectomy group. The mean RC in the hemilaminectomy group was 34.6% and in the mini-hemilaminectomy group 62.6%. Our results showed a significantly greater reduction of spinal cord compression for mini-hemilaminectomy compared to hemilaminectomy. Additionally, mini-hemilaminectomy could be a preferred method due to its minimal invasiveness and easier access to lateral fenestration. PMID:28386545

    Pregnancy is characterized by a series of maternal hormonal and metabolic changes which can affect thyroid function and the course of thyroid dysfunction in different ways. Moreover, hypothyroidism is also associated with obstetric complications and morbidity to the fetus. The aim of the present study was to evaluate the influence of hypothyroidism during the course of pregnancy and the necessity of adjusting the dose of levothyroxine. We prospectively followed 16 patients with previous diagnosis of hypothyroidism. In ten patients (62.5%) it was necessary to raise the dose of levothyroxine, with a median increase of 20.7%. One pregnancy was complicated by premature amniorrhexis and two by pre-eclampsia. The screening for congenital hypothyroidism was negative in all newborns. We conclude that it is very important to offer screening to high-risk patients who wish to become pregnant. Dose adjustment based on serum levels of thyroid-stimulating hormone (TSH) is essential. In patients in whom TSH is not measured during the first weeks of pregnancy, a good approach could be to increase the dose of replacement therapy by 20-25% to avoid hypothyroidism.

    From 1974 to 1980, 69 patients with ith diffuse malignant mesothelioma were prospectively evaluated. The initial site of involvement was the pleura in 57 patients and the peritoneum in 12. Previous asbestos exposure was found in 53 patients (77%), with a shorter period of latency for peritoneal (mean, 28 years) than for ith pleural mesothelioma (mean, 35 years) than for pleural mesothelioma (mean, 35 years). Other associated exposure or diseases included talc, mica, familial Mediterranean fever, and diffuse lymphocytic lymphoma (one patient each). Thrombocytosis was common, as were thromboembolic episodes. Survival was significantly better for patients with an epithelial subtype, with pleural versus peritoneal mesothelioma, and for those under 65 years of age. Surgery was never curative, but its extent was correlated with survival and earlier diagnosis. Results of chemotherapy with doxorubicin and 5-azacytidine yielded a somewhat better survival rate than a combined program with doxorubicin and radiotherapy. Survival after chemotherapy was correlated with performance status, response to chemotherapy, and extent of previous surgery.

    Q-switched nanosecond lasers demonstrated their efficacy in treating most types of tattoos, but complete disappearance is not always achieved even after performing numerous laser sessions. Picosecond lasers are supposed to be more efficient in clearing tattoos than nanosecond lasers, but prospective comparative data remain limited. To compare on different types of tattoos the efficacy of a nanosecond laser with two types of picosecond lasers. We conducted a prospective randomized study performed from December 2014 to June 2016 on adult patients with all types of tattoos. The tattoos were divided into two halves of equal size. After randomization, half of the tattoo was treated with a picosecond laser and the other half with a nanosecond laser. The evaluation was performed on standardized pictures performed before treatment and 2 months after the last session, by two physicians, not involved in the treatment, blinded on the type of treatments received. The main end point was a clearance above 75% of the tattoos. A total of 49 patients were included. Professional tattoos represented 85.7%, permanent make-up 8.2% and non-professional tattoo 6.1%. The majority were black or blue and 10.2% were polychromatic. No patient was lost during follow-up. A reduction of 75% or more of the colour intensity was obtained for 33% of the tattoos treated with the picosecond lasers compared to 14% with the nanosecond laser (P = 0.008). An improvement superior to 75% was obtained in 34% monochromic black or blue tattoos with the picosecond lasers compared to 9% for the nanosecond laser. Only one of the five polychromic tattoos achieved more than 75% of improvement with the two types of laser. Our results show a statistically significant superiority of the picosecond lasers compared to the nanosecond laser for tattoo clearance. However, they do not show better efficacy for polychromic tattoos and the difference in terms of side-effects was also minimal with a tendency of picosecond

    Introduction: The acromio-clavicular (AC) joint is very susceptible to degenerative processes that result in pain and functional impairment. One common modality of treatment has been local infiltration of the joint space. Although this procedure has produced notable positive results, needle misplacement occurs frequently. The aim of this investigation is to evaluate the effects of an intra articular infiltration by comparing precise needle placement into the joint space using high-resolution-ultrasound with the conventional palpation technique. Methods: This prospective and randomized pilot study analysed 20 patients who were assigned either to the 'ultrasound' or the 'palpation' group. Clinical examinations were performed before treatment and at 1 h, 1 week and 3 weeks after a single infiltration of local anaesthetic and corticoid carried out by one specialist. Results: In both groups significant improvement in pain and function was obtained up to one-week post injection. Function remained significantly improved until the last follow-up and did not differ between the two groups. The agent was administered in all patients into the joint space in the ultrasound group. Conclusion: Ultrasound guided infiltration of the AC joint is an easily achieved procedure without any complications. However, clinical follow-up did not differ between free-hand and ultrasound-guided AC joint space infiltration.

    To evaluate whether continuous hemihepatic inflow occlusion (HHO) during hepatectomy can be safer than and be as effective as intermittent total hepatic inflow occlusion (THO) in reducing blood loss. Eighty patients undergoing liver resections were included in a prospective randomized study comparing the intra- and postoperative course under THO (n=40) or HHO (n=40). THO was performed with periods of 20 minutes of occlusion and 5 minutes of releasing, while HHO was performed with continuous occlusion. The surface area of liver transection, amount of blood loss, measurements of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and postoperative evolution were recorded. The two groups were similar at entry in terms of preoperative liver function and in the proportion of patients experiencing major hepatectomy. The total ischemic time of the two groups was similar (p=0.37), but the operative time in the THO group was longer than in the HHO group (p=0.02). No significant difference was found between the HHO and THO group in blood loss during liver parenchyma transection (p=0.14), the elevations of ALT and AST on the first postoperative day (ALT: p=0.12; AST: p=0.66) and postoperative morbidity (p=0.35). On the basis of our findings, if it is feasible, continuous HHO is recommended for complex liver resection.

    Background Osteoarthritis (OA) is the most common joint disease and leading cause of disability. Intra-articular (IA) administration of hyaluronic acid (HA) or corticosteroids (CS) have been previously studied, though using insufficient number of patients or short follow-up periods. Objective We evaluate HA and CS in patients with knee OA in terms of clinical efficacy over 12 months. Methods We used a prospective, randomized study with parallel groups. Randomized patients received IA injections of HA or betamethasone (BM). The primary outcomes were improvement in pain using Visual Analog Scale and function in the Western Ontario and McMaster University Osteoarthritis Index (Likert scale). Follow-up visits were scheduled at 3 months, 6 months, 9 months, and 12 months. Results A total of 200 patients were included. Pain was significantly reduced in both groups at the first follow-ups. At 12 months, the mean pain reduction in the HA group was 33.6% (95% CI: 31.1–36.1) compared to 8.2% (95% CI: 5.2–11.1) in BM (P<0.0001). Function improvement was higher in HA through every visit, and mean improvement at 12 months was 47.5% (95% CI: 45.6–49.3) in HA patients vs 13.2% (95% CI: 11.4–14.9) in the BM group (P<0.0001). All patients from both groups achieved the Minimal Clinically Important Improvement (MCII) for both pain and function up to 6 months. At 9 months and 12 months, the MCII figures were higher in HA group with ≥80% compared to ≤10% in BM group (P<0.0001). Adverse reactions were rare and related to the administration procedure. Conclusion Both treatments effectively controlled OA symptoms. BM showed higher short-term effectiveness, while HA showed better long-term effectiveness, maintaining clinical efficacy in a large number of patients 1 year after administration.

    Summary Background Vertebral compression fractures (VCFs) treated non-operatively can diminish function and quality of life, and lead to chronic health effects. The short-term safety and effectiveness of vertebroplasty for symptomatic VCFs are well-documented, but long-term follow-up is needed. Purpose The aim of this paper was to analyse a multicenter international experience of 200 compression fractures treated with percutaneous vertebroplasty (VP) and compare the results of this procedure with the result of 200 patients treated conservatively. To estimate cost-effectiveness of VP compared to conservative care in terms of: pain reduction, quality of life, complications, secondary fractures and mortality. Materials and methods 400 patients have been enrolled in a prospective randomized controlled study with painful VCFs with bone edema on MR imaging, local back pain for 6 weeks or less, osteoporosis and aged 55 years or older; after obtaining informed consent patients are included and randomized for VP or conservative care. Before treatment and at follow-up with regular intervals during 1-year period were administered to patients standard questionnaires addressing: clinical symptoms, pain medication, Visual Analogue Scale (VAS) score for pain, Oswestry Disability Index (ODI) score to evaluate functional activity. Results 200 patients treated with PV compared with 200 patients treated conservatively had significantly better VAS and used less analgesics 1 day after treatment. Twenty-four hours after VP, there was a reduction in pain scores and an improvement in physical functions, whereas remain unchanged in the patients treated conservatively. Conclusions Pain relief and improvement of mobility and function after PV is immediate and significantly better in the short term compared with non-surgical care treatment. PMID:28228788

    Full Text Available Abstract Background The scaphoid bone is the most commonly fractured of the carpal bones. In the Netherlands 90% of all carpal fractures is a fracture of the scaphoid bone. The scaphoid has an essential role in functionality of the wrist, acting as a pivot. Complications in healing can result in poor functional outcome. The scaphoid fracture is a troublesome fracture and failure of treatment can result in avascular necrosis (up to 40%, non-union (5-21% and early osteo-arthritis (up to 32% which may seriously impair wrist function. Impaired consolidation of scaphoid fractures results in longer immobilization and more days lost at work with significant psychosocial and financial consequences. Initially Pulsed Electromagnetic Fields was used in the treatment of tibial pseudoarthrosis and non-union. More recently there is evidence that physical forces can also be used in the treatment of fresh fractures, showing accelerated healing by 30% and 71% reduction in nonunion within 12 weeks after initiation of therapy. Until now no double blind randomized, placebo controlled trial has been conducted to investigate the effect of this treatment on the healing of fresh fractures of the scaphoid. Methods/Design This is a multi center, prospective, double blind, placebo controlled, randomized trial. Study population consists of all patients with unilateral acute scaphoid fracture. Pregnant women, patients having a life supporting implanted electronic device, patients with additional fractures of wrist, carpal or metacarpal bones and pre-existing impairment in wrist function are excluded. The scaphoid fracture is diagnosed by a combination of physical and radiographic examination (CT-scanning. Proven scaphoid fractures are treated with cast immobilization and a small Pulsed Electromagnetic Fields bone growth stimulating device placed on the cast.

    Among the multiple modalities of treatments available in managing chronic spinal pain, including surgery and multiple interventional techniques, epidural injections by various routes, such as interlaminar epidural injections, caudal epidural injections, transforaminal epidural injections, and percutaneous adhesiolysis are common. Even though the complications of fluoroscopically directed epidural injections are fewer than blind epidural injections, and have better effectiveness, multiple complications have been reported in scattered case reports, with only minor complications in randomized or non-randomized studies and systematic reviews. Thus, prospective studies with large patient series are essential to determine the types and incidences of complications. A prospective, non-randomized study of patients undergoing interventional techniques from May 2008 to December 2009. A private interventional pain management practice, a specialty referral center in the United States. To assess the complication rate of fluoroscopically directed epidural injections. This study was carried out over a period of 20 months and included over 10,000 procedures: 39% caudal epidurals, 23% cervical interlaminar epidurals, 14% lumbar interlaminar epidurals, 13% lumbar transforaminal epidurals, 8% percutaneous adhesiolysis, and 3% thoracic interlaminar epidural procedures. All of the interventions were performed under fluoroscopic guidance in an ambulatory surgery center by one of 3 physicians. The complications encountered during the procedure and postoperatively were prospectively evaluated. Measurable outcomes employed were intravascular entry of the needle, profuse bleeding, local hematoma, bruising, dural puncture and headache, nerve root or spinal cord irritation with resultant injury, infectious complications, vasovagal reactions, and facial flushing. Intravascular entry was higher for adhesiolysis (11.6%) and lumbar transforaminal (7.9%) procedures compared to other epidurals which

    Full Text Available INTRODUCTION Studies completed in the last decade of the 20th century showed benefits of carotid endarterectomy in the prevention of stroke in patients with a high-grade stenosis of the internal carotid artery. OBJECTIVE The aim of this prospective, randomized study was the comparison of early and long-term results between the conventional and eversion carotid endarterectomy, and literature review. METHOD By the method of random choice, 103 patients were operated on using the eversion carotid endarterectomy and 98 patients using the conventional technique. Operative treatment was carried out under general anaesthesia. Following the clammping of the carotid artery, retrograde blood pressure was determined by a direct puncture of the internal carotid artery above the stenotic lesions. In patients with retrograde pressure below 20 mm Hg intraluminal shunting was routinely performed. Early results were estimated (during the first seven postoperative days based on mortality, central neurological complications (stroke, TIA and cranial or cervical nerve lesions. Long-term results were estimated (after at least two years based on long-term survival rate, central neurological complications (stroke, TIA and the incidence of haemodynamically significant restenosis of the carotid artery treated by endarterectomy. RESULTS The average time of clamming of the internal carotid artery in the eversion carotid anderectomy group was 5.36 minutes shorter than in the group treated by the conventional technique. Student's t-test showed a statistically highly significant difference in the time needed for clamming of the internal carotid artery between the two groups. The average duration of eversion endarterectomy (82 minutes was most often 19 minutes shorter than the duration of the conventional endarterectomy (101 minutes. Student's t-test showed a statistically highly significant difference in the average length of surgeries. The distal intimal fixation was more

    The objective of this study was to compare the air leak duration of two regulated chest tube modes following pulmonary lobectomy. This is a prospective randomized trial on 100 consecutive pulmonary lobectomies (2010-11) performed for lung cancer. A single 24-French chest tube was connected to an electronic system capable of maintaining the pleural pressure within preset values (regulated suction mode) or within a physiological range (regulated seal mode). Patients were randomized to two groups: Group 1, regulated individualized suction (range: -11 to -20 cmH2O, according to lobectomy type); Group 2, regulated seal (-2 cmH2O). The main endpoint was the duration of air leak (h) calculated from the end of the operation to a value consistently below 20 ml/min. Patients with prolonged air leak (>168 h) were connected to a portable device before discharge. Their air leak duration was considered as 192 h. The sample size was calculated to detect 1-day difference in air leak duration with a statistical power of 80%. The two groups were well matched for several baseline and surgical characteristics. No crossovers occurred between groups. The average air leak duration (Group 1: 28 vs Group 2: 22.2, P = 0.6), and the number of patients with prolonged air leak (Group 1: 5 vs Group 2: 4, P = 0.7) and with other complications (Group 1: 6 patients vs Group 2: 7 patients, P = 0.9) were similar between the groups. Sixteen patients of Group 1 and 21 of Group 2 had an air leak present immediately after extubation. Among them, patients of Group 2 (regulated seal) had an air leak lasting 34.5 h less than those of Group 1 (regulated suction) (52.9 vs 87.4, P = 0.07). Regulated seal is as effective and safe as regulated suction in managing chest tubes following lobectomy. This information demonstrates with objective data the non-superiority of regulated suction vs regulated seal and may assist in future investigations on regulated pleural pressure.

    Full Text Available Background. Mobile health and digital medicine technologies are becoming increasingly used by individuals with common, chronic diseases to monitor their health. Numerous devices, sensors, and apps are available to patients and consumers–some of which have been shown to lead to improved health management and health outcomes. However, no randomized controlled trials have been conducted which examine health care costs, and most have failed to provide study participants with a truly comprehensive monitoring system. Methods. We conducted a prospective randomized controlled trial of adults who had submitted a 2012 health insurance claim associated with hypertension, diabetes, and/or cardiac arrhythmia. The intervention involved receipt of one or more mobile devices that corresponded to their condition(s (hypertension: Withings Blood Pressure Monitor; diabetes: Sanofi iBGStar Blood Glucose Meter; arrhythmia: AliveCor Mobile ECG and an iPhone with linked tracking applications for a period of 6 months; the control group received a standard disease management program. Moreover, intervention study participants received access to an online health management system which provided participants detailed device tracking information over the course of the study. This was a monitoring system designed by leveraging collaborations with device manufacturers, a connected health leader, health care provider, and employee wellness program–making it both unique and inclusive. We hypothesized that health resource utilization with respect to health insurance claims may be influenced by the monitoring intervention. We also examined health-self management. Results & Conclusions. There was little evidence of differences in health care costs or utilization as a result of the intervention. Furthermore, we found evidence that the control and intervention groups were equivalent with respect to most health care utilization outcomes. This result suggests there are not large

    In oral and maxillofacial outpatient surgery, sedation techniques are an important component in patient management for a wide variety of surgical procedures. Fentanyl and midazolam are commonly used sedatives with different mechanisms of action and specific analgesic or amnestic properties. This study examined whether the order of their administration would affect a patient's pain perception or procedural vital signs. After institutional review board approval and written informed consent, a prospective, randomized, parallel-group clinical trial was conducted in patients who planned to undergo removal of at least 2 third molars under intravenous moderate sedation. Patients were randomly assigned to 1 of 2 groups. The fentanyl-first group received fentanyl and then midazolam; the midazolam-first group received midazolam and then fentanyl. Recollection of the intraoperative pain score was assessed 24 hours after surgery using the Wong-Baker FACES pain scale. The Mann-Whitney U test was used to assess for the presence of a statistically significant difference between the 2 groups. Statistically significant differences in procedural vital sign fluctuations were examined using the t test. Patients' satisfaction with the procedure was assessed and intergroup comparisons were made. Sixty-six patients were enrolled, 1 of whom did not complete the study. Recollected procedural pain scores at 24 hours after surgery were not statistically different between groups. Median scores on the Wong-Baker FACES pain scale for the 2 groups were 2.0 (interquartile range, 3.1) for the fentanyl-first group and 1.5 (interquartile range, 2.5) for the midazolam-first group (P = .333). There was no statistical difference in the change in vital signs from baseline to 2 surgical end points in the 2 groups. In addition, patient satisfaction with the procedure did not statistically differ between the 2 groups. In this study, selective sequencing of midazolam or fentanyl during an intravenous

    With the continuing improvements in implants for distal humerus fractures, it is expected that newer types of plates, which are anatomically precontoured, thinner and less irritating to soft tissue, would have comparable outcomes when used in a clinical study. The purpose of this study was to compare the clinical and radiographic outcomes in patients with distal humerus fractures who were treated with orthogonal and parallel plating methods using precontoured distal humerus plates. Sixty-seven patients with a mean age of 55.4 years (range 22-90 years) were included in this prospective study. The subjects were randomly assigned to receive 1 of 2 treatments: orthogonal or parallel plating. The following results were assessed: operating time, time to fracture union, presence of a step or gap at the articular margin, varus-valgus angulation, functional recovery, and complications. No intergroup differences were observed based on radiological and clinical results between the groups. In our practice, no significant differences were found between the orthogonal and parallel plating methods in terms of clinical outcomes, mean operation time, union time, or complication rates. There were no cases of fracture nonunion in either group; heterotrophic ossification was found 3 patients in orthogonal plating group and 2 patients in parallel plating group. In our practice, no significant differences were found between the orthogonal and parallel plating methods in terms of clinical outcomes or complication rates. However, orthogonal plating method may be preferred in cases of coronal shear fractures, where posterior to anterior fixation may provide additional stability to the intraarticular fractures. Additionally, parallel plating method may be the preferred technique used for fractures that occur at the most distal end of the humerus.

    Multimodal pain management has had a significant effect on improving total joint arthroplasty recovery and patient satisfaction. There is literature supporting that intravenous (IV) acetaminophen reduces postoperative pain and narcotic use in the total joint population. However, there are no studies comparing the effectiveness of IV vs oral (PO) acetaminophen as part of a standard multimodal perioperative pain regimen. One hundred twenty patients undergoing hip and knee arthroplasty surgeries performed by one joint arthroplasty surgeon were prospectively randomized into 2 groups. Group 1 (63 patients) received IV and group 2 (57 patients) received PO acetaminophen in addition to a standard multimodal perioperative pain regimen. Each group received 1 gram of acetaminophen preoperatively and then every 6 hours for 24 hours. Total narcotic use and visual analog scale (VAS) scores were collected every 4 hours postoperatively. The 24-hour average hydromorphone equivalents given were not different between groups (3.71 vs 3.48) at 24 hours (P = .76), or at any of the individual 4-hour intervals. The 24-hour average visual analog scale scores in group 1 (IV) was 3.00 and in group 2 (PO) was 3.40 (P = .06). None of the 4-hour intervals were significantly different except the first interval (0-4 hour postoperatively), which favored the IV group (P = .03). The use of IV acetaminophen may have a role when given intraoperatively to reduce the immediate pain after surgery. Following that, it does not provide a significant benefit in reducing pain or narcotic use when compared with the much less expensive PO form. Copyright © 2016 Elsevier Inc. All rights reserved.

    To investigate the effects of music on anxiety and perception of pain during office hysteroscopy. Prospective randomized trial (Canadian Task Force classification I). Major university medical center. Three hundred fifty-six patients were enrolled between July 2012 and January 2013. Hysteroscopy was performed in a dedicated ambulatory room, using vaginoscopy and without any type of anesthesia. A Bettocchi hysteroscope 5 mm in diameter was used. All procedures were performed by the same surgeon, a gynecologist with special interest in hysteroscopy. Data collected included age, body mass index, number of vaginal deliveries, educational achievement level, and history of endometrial surgery (curettage and/or hysteroscopy). For each patient, vital parameters such as blood pressure, heart rate, and respiratory rate were recorded 15 minutes before the procedure and during hysteroscopy after traversing the cervix. Wait time before surgery and the duration of the procedure were also recorded. A completed Italian version of the state anxiety questionnaire (State-Trait Anxiety Inventory) and a visual analog scale (VAS) were administered to each patient before and after the procedure. The t test and Mann-Whitney U test was used when appropriate to compare the 2 groups. Statistical significance was accepted at p = .05. During surgery, systolic blood pressure and heart rate were significantly lower in the music group compared with the no music group. Women in the music group experienced significantly lower anxiety after hysteroscopy and less pain during the procedure, and a significant decrease in both anxiety and pain scores after hysteroscopy. Postoperative State-Trait Anxiety Inventory form Y1 and VAS scores were significantly lower in the music group. Music can be useful as a complementary method to control anxiety and reduce perception of pain. The patient is more relaxed and experiences less discomfort. Copyright © 2014.

    Purpose Management of empyema has been debated in the literature for decades. Although both primary video-assisted thoracoscopic surgery (VATS) and tube thoracostomy with pleural instillation of fibrinolytics have been shown to result in early resolution when compared to tube thoracostomy alone, there is a lack of comparative data between these modes of management. Therefore, we conducted a prospective, randomized trial comparing VATS to fibrinolytic therapy in children with empyema. Methods After Institutional Review Board approval, children defined as having empyema by either loculation on imaging or more than 10,000 white blood cells/μL were treated with VATS or fibrinolysis. Based on our retrospective data using length of postoperative hospitalization as the primary end point, a sample size of 36 patients was calculated for an α of .5 and a power of 0.8. Fibrinolysis consisted of inserting a 12F chest tube followed by infusion of 4 mg tissue plasminogen activator mixed with 40 mL of normal saline at the time of tube placement followed by 2 subsequent doses 24 hours apart. Results At diagnosis, there were no differences between groups in age, weight, degree of oxygen support, white blood cell count, or days of symptoms. The outcome data showed no difference in days of hospitalization after intervention, days of oxygen requirement, days until afebrile, or analgesic requirements. Video-assisted thoracoscopic surgery was associated with significantly higher charges. Three patients (16.6%) in the fibrinolysis group subsequently required VATS for definitive therapy. Two patients in the VATS group required ventilator support after therapy, one of whom required temporary dialysis. No patient in the fibrinolysis group clinically worsened after initiation of therapy. Conclusions There are no therapeutic or recovery advantages between VATS and fibrinolysis for the treatment of empyema; however, VATS resulted in significantly greater charges. Fibrinolysis may pose less

    Full Text Available Abstract Background ERCP practically requires moderate to deep sedation controlled by a combination of benzodiazepine and opiod. Propofol as a sole agent may cause oversedation. A combination (cocktail of infused propofol, meperidine, and midazolam can reduce the dosage of propofol and we hypothesized that it might decrease the risk of oversedation. We prospectively compare the efficacy, recovery time, patient satisfactory, and side effects between cocktail and conventional sedations in patients undergoing ERCP. Methods ERCP patients were randomized into 2 groups; the cocktail group (n = 103 and the controls (n = 102. For induction, a combination of 25 mg of meperidine and 2.5 mg of midazolam were administered in both groups. In the cocktail group, a bolus dose of propofol 1 mg/kg was administered and continuously infused. In the controls, 25 mg of meperidine or 2.5 mg/kg of midazolam were titrated to maintain the level of sedation. Results In the cocktail group, the average administration rate of propofol was 6.2 mg/kg/hr. In the control group; average weight base dosage of meperidine and midazolam were 1.03 mg/kg and 0.12 mg/kg, respectively. Recovery times and patients’ satisfaction scores in the cocktail and control groups were 9.67 minutes and 12.89 minutes (P = 0.045, 93.1and 87.6 (P P Conclusions Cocktail sedation containing propofol provides faster recovery time and better patients’ satisfaction for patients undergoing ERCP. However, mild degree of desaturation may still develop. Trial registration ClinicalTrials.gov, NCT01540084

    Laparoscopic appendectomy is probably the technique of choice in acute appendicitis. Single port laparoscopic surgery (SILS) has been proposed as an alternative technique. The objective of this study is to compare the safety and efficacy of SILS against conventional laparoscopic appendectomy (LA). From January 2011 to September 2012, 120 patients with acute appendicitis were prospectively randomized; 60 for SILS and 60 for LA. Patients between 15 to 65 years were selected, with onset of symptoms less than 48h. We compared BMI, surgery time, start of oral intake, hospital stay, postoperative pain, pathology and costs. The median age, BMI, sex and time of onset of symptoms to diagnosis were similar. There were no statistically significant differences in the operative time, start of oral intake or hospital stay. There was a significant difference in postoperative pain being higher in SILS (4±1.3) than in LA (3.3±0.5) with a P=.004. Flemonous appendicitis predominated in both groups in a similar percentage. A total of 3 cases with intra-abdominal abscess (SILS 2, LA 1) required readmission and resolved spontaneously with intravenous antibiotic treatment. One case of SILS required assistance by a 5mm trocar in the RLC for drainage placement. The cost was higher in SILS due the single port device. SILS appendectomy is safe, effective and has similar results to LA in selected patients, and although the cost is greater, the long term results will determine the future of this technique.

    To evaluate the efficacy and safety of auto-crosslinked hyaluronic acid (HA) gel for preventing intrauterine adhesion (IUA) after hysteroscopic adhesiolysis. A prospective, randomized, double blinded and controlled clinical trial (level I) was performed. According to American Fertility Society (AFS) scoring system, 120 patients (treatment group: 60 cases, control group: 60 cases) with moderate to severe IUA were enrolled. Upon completion of adhesiolysis, a Foley balloon catheter was first introduced into the uterine cavity and then 3 ml of auto-crosslinked HA gel for patients in the treatment group; patients in the control group, however, only received Foley balloon catheter. Second-look hysteroscopic examination was performed to all patients at 3 months postoperatively for evaluation of IUA. Primary endpoint was the reduction rate of IUA at 3 months after surgery. The secondary endpoints include total AFS score, score of each individual AFS category. At 3 months after surgery, auto-crosslinked HA gel resulted in significantly higher effective rate for reduction of adhesion, the effective rate were 76% (42/55) and 48% (27/56) respectively (P = 0.000 9); the total AFS score of treatment group was 2.1 ± 1.1, and significantly lower than that of control group (3.7 ± 2.5, P = 0.000 8). Application of auto-crosslinked HA gel after surgery significantly enhanced the improvement for each individual patient with regard to their adhesive type and menstrual pattern (P = 0.037 8, P = 0.000 4). The treatment group had significantly lower proportion of patients with moderate to severe adhesive stages than that of control group [13% (7/55) versus 38% (21/56), P = 0.000 6]. No adverse events and complications were observed. Auto-crosslinked HA gel coule be able to reduce IUA, decrease adhesion severity, and improve menopause postoperatively. This absorbable auto-crosslinked HA gel is proposed as a barrier for preventing IUA after intrauterine procedures.

    Hernia is one of the most widely studied processes, and the search for excellence has become the final aim. However, many controversies remain to be resolved. The objective of the present study was to analyze postoperative pain and costs using two techniques of primary inguinal hernia repair. We performed a prospective, randomized study of 54 patients who underwent surgical repair of inguinal hernia through either the Lichtenstein or the Shouldice technique between June 2001 and May 2002. The following variables were analyzed: age, location and type of hernia, evaluation of tolerance to local anesthesia, surgical technique, operating time, pain at days 1, 3 and 5 after surgery, analgesic consumption, days until driving could be resumed, days off work, and occupation. The patient groups were similar, with no significant differences in age, location or type of hernia. For Lichtenstein hernioplasty, operating time was lower (p < 0.01); pain evaluation showed no significant differences on days 1 and 3 after surgery but was higher on day 5 (p = 0.064). No significant differences were found in analgesic consumption, time before driving could be resumed, or days off work. Freelance patients returned to work earlier, independently of the surgical technique performed. The cost of the Lichtenstein technique was 235 euros compared with 180 euros for the Shouldice technique and this difference was statistically significant (p < 0.05). In the hands of expert surgeons, the Shouldice technique is the procedure of choice in the repair of primary hernias. The results are just as satisfactory as those obtained with Lichtenstein hernioplasty and hospital costs are lower.

    We compared the short-term efficacy of rigid versus soft lateral wedge arch support (LWAS) insoles for patients with knee osteoarthritis (OA), as assessed using the International Classification of Functioning, Disability and Health (ICF) system, through a prospective, double-blind, randomized controlled trial.Participants who fulfilled the combined radiographic and clinical criteria for knee OA, as defined by the American College of Rheumatology, were randomly prescribed 1 pair of rigid or soft LWAS insoles. Body functions and structures were evaluated according to Kellgren-Lawrence scores, the Foot Posture Index, Hospital Anxiety and Depression Scale scores, the pain-pressure threshold, postural stability, dynamic balance, and fall risk; activities and participation were assessed according to 10-m fast speed walking, stair climbing and chair rising times, and Chronic Pain Grade questionnaire responses; and knee OA-related health status was evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS). Hospital Anxiety and Depression Scale scores, the pain-pressure threshold, physical activity, balance, Chronic Pain Grade questionnaire responses, and the KOOS were recorded before treatment and at 1-, 2-, and 3-month follow-ups.We enrolled 90 participants, 70 women and 20 men, with mean ages of 60.6 ± 10.8 and 63.1 ± 10.8 years in the rigid and soft LWAS insole groups, respectively. Repeated-measures analysis of covariance revealed significant time × group effect improvements in pain (P = 0.008 for the KOOS), stair ascent time (P = 0.003), daily living function (P = 0.003 for the KOOS), sports and recreation function (P = 0.012 for the KOOS), and quality of life (P = 0.021 for the KOOS) in the soft LWAS insole group.Patients with knee OA who used soft LWAS insoles for a short term showed more significant improvement than did those who used rigid LWAS insoles in pain, physical activity, daily living function, sports and recreation function

    A potential accumulation of hydrocarbon that describes significant and conceivable drilling target is related to prospect. Possibility of success estimation, assuming discovery of hydrocarbons and the potential recoverable quantities range under a commercial development program are the basis of Prospect evaluation activities. The objective was to find the new shallow prospects in reservoir sandstone of I -Formation in Malay basin. The prospects in the study area are mostly consisting of faulted structures and stratigraphic channels. The methodology follows seismic interpretation and mapping, attribute analysis, evaluation of nearby well data i.e., based on well - log correlation. The petrophysical parameters analogue to nearby wells was used as an input parameter for volumetric assessment. Based on analysis of presence and effectiveness, the prospect has a complete petroleum system. Two wells have been proposed to be drilled near the major fault and stratigraphic channel in I-35 reservoir that is O-1 and O-2 prospects respectively. The probability of geological success of prospect O-1 is at 35% while for O-2 is 24%. Finally, for hydrocarbon in place volumes were calculated which concluded the best estimate volume for oil in O-1 prospect is 4.99 MMSTB and O-2 prospect is 28.70 MMSTB while for gas is 29.27 BSCF and 25.59 BSCF respectively.

    BACKGROUND Nonnutritive sweeteners, such as aspartame, sucralose and stevioside, are widely consumed, yet their long-term health impact is uncertain. We synthesized evidence from prospective studies to determine whether routine consumption of non-nutritive sweeteners was associated with long-term adverse cardiometabolic effects. METHODS We searched MEDLINE, Embase and Cochrane Library (inception to January 2016) for randomized controlled trials (RCTs) that evaluated interventions for nonnutritive sweeteners and prospective cohort studies that reported on consumption of non-nutritive sweeteners among adults and adolescents. The primary outcome was body mass index (BMI). Secondary outcomes included weight, obesity and other cardiometabolic end points. RESULTS From 11 774 citations, we included 7 trials (1003 participants; median follow-up 6 mo) and 30 cohort studies (405 907 participants; median follow-up 10 yr). In the included RCTs, nonnutritive sweeteners had no significant effect on BMI (mean difference −0.37 kg/m2; 95% confidence interval [CI] −1.10 to 0.36; I2 9%; 242 participants). In the included cohort studies, consumption of nonnutritive sweeteners was associated with a modest increase in BMI (mean correlation 0.05, 95% CI 0.03 to 0.06; I2 0%; 21 256 participants). Data from RCTs showed no consistent effects of nonnutritive sweeteners on other measures of body composition and reported no further secondary outcomes. In the cohort studies, consumption of nonnutritive sweeteners was associated with increases in weight and waist circumference, and higher incidence of obesity, hypertension, metabolic syndrome, type 2 diabetes and cardiovascular events. Publication bias was indicated for studies with diabetes as an outcome. INTERPRETATION Evidence from RCTs does not clearly support the intended benefits of nonnutritive sweeteners for weight management, and observational data suggest that routine intake of nonnutritive sweeteners may be associated with

    AIM: Postoperative gastrointestinal-tract motility is normally delayed. Early feeding after colorectal surgery has beenreposed recently, but late feeding is common. Gastrografin not only enhances bowel peristalsis, but also decreases bowel-wall edema. Whether contrast medium allows early oral feeding and reduces the duration of hospitalization requires clarification.METHODS: Fifty patients underwent elective colorectal surgery in a regional medical center. Patients were prospectively randomized into a Gastrografin group or control group (n = 25 each). Patients in the Gastrografin group began their feeding schedule with 100 mL of 5% dextrose water with 100 mL of Gastrografin on postoperative d 3 and were advanced to a full liquid diet when the contrast reached the colon in 4 h. Patients in the control group began their feeding schedule with 200 mL of 5% dextrosewater on postoperative d 3 and were advanced to a full liquid diet after the passage of flatus and stool. Nasogastric tubes were inserted for persistent postoperative vomiting. Fullness, nausea, vomiting, complications, time of anesthesia, time of operation, time of mobilization, time of oral feeding, and duration of hospital stay were recorded and analyzed with Student's t-test.RESULTS: In the Gastrografin group, one patient hadaspiration pneumonia and one patient had anastomotic leakage resulting in sepsis and eventual death. This mortality was excluded from the subsequent statistical analysis. In the control group, two patients had wound infections. There was no significant difference between the two groups at the time of anesthesia, time of operation, or time of mobilization. There were significant differences between the two groups in the time of oral feeding (3.3±0.3 d in the Gastrografin group vs4.8±0.4 d in the control group; P = odds ratio--, 95%CI [-0.5 to +0.7 d]) and in the length of hospital stay (7.6±1.1 d in the Gastrografingroup vs10.2±1.3 d in the control group; P = odds ratio--, 95% CI

Methods: This prospective, non-randomized intervention study was carried out at the department of general internal medicine at a tertiary university hospital. Two hundred medical inpatients living in the community and aged over 60 years were included. Ninety-nine patients received interventions and 101 received standard care. Control/intervention allocation was determined by geographic selection. Interventions consisted of a comprehensive medication review, improved discharge planning, post-discharge telephone follow-up, and liaison with the patient's general practitioner. The main outcome measures recorded were readmissions and hospital nights 12 months after discharge. Separate analyses were made for 12-month survivors and from an intention-to-treat perspective. Comparative analyses were made between groups as well as within groups over time. Results: After 12 months, survivors in the control group had 125 readmissions in total, compared with 58 in the intervention group (Mann–Whitney U test, P = 0.02. For hospital nights, the numbers were 1,228 and 492, respectively (P = 0.009. Yearly admissions had increased from the previous year in the control group from 77 to 125 (Wilcoxon signed-rank test, P = 0.002 and decreased from 75 to 58 in the intervention group (P = 0.25. From the intention-to-treat perspective, the same general pattern was observed but was not significant (1,827 versus 1,008 hospital nights, Mann–Whitney test, P = 0.054.

    We evaluated whether cardiac autonomic changes could be associated with different extent of sympathetic nerve resection in the management of essential palmar hyperhidrosis. Sixty patients with essential palmar hyperhidrosis were randomly allocated to undergo excision of T3 ganglia (sympathicectomy group; n = 30) or to interruption of sympathetic chain at the T2 to T3 level with ganglion sparing (sympathicotomy group; n = 30). Time and frequency domains were measured with a 24-Holter monitor during daytime, nighttime, and 24-hour periods at different interval points (7 days before operation; 24 hours; and 1, 3, and 6 months later), and the differences were statistically compared. Clinical outcomes were also evaluated. Twenty-eight of 30 patients of the sympathectomy and 29 of 30 patients of the sympathicotomy group completed the study. In both groups, we observed a significant increase (p 50 ms; high frequency; and a significant decrease (p sympathectomy group than in the sympathicotomy group. Clinical outcomes were similar between the two groups. Endoscopic thoracic sympathectomy caused a shift of sympathovagal balance toward parasympathetic tone that seems to be associated with the extent of denervation.

    Backround Sugammadex is a reversal agent with well known advantages but it’s effects on haemostasis and bleeding have been a topic of interest. Septoplasty is a common surgical procedure with postoperative respiratory complications and bleeding. The aim of this study is to investigate the effects of sugammadex on postoperative coagulation parameters and bleeding after septoplasty procedure. Material/Methods In this randomized controlled study, fifty patients were grouped into two groups; neostigmine (Group N) vs. sugammadex (Group S). For the evaluation of PT, aPTT and INR, blood samples were taken for at the postoperative 120th minutes and alteration of these values with respect to preoperative values were documented. Postoperative bleeding was measured by evaluating the amount of blood absorbed on the nasal tip dressing during 3 hours postoperatively. Results Postoperative bleeding amount was significantly higher in the Group S compared to Group N (p=0.013). No significant difference was observed between two groups according to coagulation parameters (PT; p=0.953, aPTT; p=0.734, INR; p=0.612). Conclusions Sugammadex was associated with higher amount of postoperative bleeding than neostigmine in septoplasty patients. In surgical procedures having high risk of bleeding the safety of sugammadex need to be verified. PMID:26271275

    Previous literature has shown that propofol has ideal anesthetic properties for patients undergoing colonoscopy, a common procedure at outpatient surgery centers. However, there is a paucity of information regarding patient satisfaction with propofol. The aim of this study was to evaluate patient satisfaction with propofol compared with nonpropofol (fentanyl/midazolam) anesthesia for outpatient colonoscopies. Safety and complications were secondary end points. This study was a double-blind, randomized, parallel-group controlled clinical trial (NCT 02937506). This study was conducted at a single ambulatory surgery center at an urban teaching community health system. Patients were scheduled for outpatient colonoscopy. Those with high-risk cardiac or pulmonary disease were excluded. Anesthesia personnel administered either fentanyl/midazolam (n = 300) or propofol (n = 300) for sedation during outpatient colonoscopy. A single, highly experienced endoscopist performed all colonoscopies. The primary outcomes measured were patient satisfaction (5-point Likert scale) and procedure complications. Data were collected on the day of endoscopy by the nursing staff of the postanesthesia care unit. A subinvestigator blinded to the randomization called patients 24 to 72 hours after discharge to obtain data on postprocedure problems and status of resumption of normal activities. Analysis was intention-to-treat. Fewer patients who received propofol remembered being awake during the procedure (2% vs 17% for fentanyl, p propofol (p propofol group (2.7% vs 11.7%, p propofol over a combination of fentanyl/midazolam as their anesthetic for outpatient colonoscopies. From a patient and provider perspective, propofol appears to be superior to fentanyl/midazolam for outpatient colonoscopy. See Video Abstract at http://links.lww.com/DCR/A445.

    Full Text Available Abstract Background Effective teaching requires an understanding of both what (content knowledge and how (process knowledge to teach. While previous studies involving medical students have compared preceptors with greater or lesser content knowledge, it is unclear whether process expertise can compensate for deficient content expertise. Therefore, the objective of our study was to compare the effect of preceptors with process expertise to those with content expertise on medical students' learning outcomes in a structured small group environment. Methods One hundred and fifty-one first year medical students were randomized to 11 groups for the small group component of the Cardiovascular-Respiratory course at the University of Calgary. Each group was then block randomized to one of three streams for the entire course: tutoring exclusively by physicians with content expertise (n = 5, tutoring exclusively by physicians with process expertise (n = 3, and tutoring by content experts for 11 sessions and process experts for 10 sessions (n = 3. After each of the 21 small group sessions, students evaluated their preceptors' teaching with a standardized instrument. Students' knowledge acquisition was assessed by an end-of-course multiple choice (EOC-MCQ examination. Results Students rated the process experts significantly higher on each of the instrument's 15 items, including the overall rating. Students' mean score (±SD on the EOC-MCQ exam was 76.1% (8.1 for groups taught by content experts, 78.2% (7.8 for the combination group and 79.5% (9.2 for process expert groups (p = 0.11. By linear regression student performance was higher if they had been taught by process experts (regression coefficient 2.7 [0.1, 5.4], p Conclusions When preceptors are physicians, content expertise is not a prerequisite to teach first year medical students within a structured small group environment; preceptors with process expertise result in at least equivalent, if not

    Rubber band ligation is a common office procedure for hemorrhoids. Triple rubber band ligation in a single session has been shown to be a safe and economical way of treating hemorrhoids. However, postligation discomfort after triple rubber band ligation is not uncommon. The aim of this study was to evaluate the effectiveness of local anesthetic injection to the banded hemorrhoidal tissue in reducing postligation discomfort. Patients attending an outpatient clinic for symptomatic hemorrhoids suitable for triple rubber band ligation were randomly assigned to two groups. In the treatment group rubber band ligation was performed at three columns of hemorrhoids, and 1 to 2 ml of 2 percent lignocaine was injected into the banded hemorrhoidal tissue. In the control group triple rubber band ligation was performed in a similar manner, but local anesthetic was not given. Patients were followed up by telephone at the second week and in the clinic after six weeks. From April to August 1996, 101 patients entered the trial and were treated with triple rubber band ligation. Sixty-two patients were randomly assigned to the local anesthetic injection group and 39 to the control group. Overall good to excellent results occurred in 89 percent of patients, and there was no difference between the two groups. Postligation pain occurred in 26 and 20 percent of patients in the treatment and control groups, respectively (P > 0.05). Postligation tenesmus occurred in 32 and 41 percent of patients in the treatment and control groups, respectively (P > 0.05). No patients suffered from septic complications or bleeding that required transfusion. Triple rubber band ligation in a single session is a safe, economical, and effective way of treating symptomatic hemorrhoids. Postligation pain and tenesmus occurred in 24 and 37 percent, respectively. Discomfort was usually tolerable. Local anesthetic injection to the banded hemorrhoidal tissue did not help to reduce postligation discomfort.

In a pediatric ward, botulinum toxin injection is a painful procedure and a stressful experience for the child. We undertook a study of the effect of the presence of a hospital clown on children treated with botulinum toxin in an outpatient setting.Methods: In total, 60 children, the majority of whom had spastic cerebral palsy, were subjected to a total of 121 botulinum toxin treatment sessions. Thirty-two children were being treated for the first time. During a 2-year period, we enrolled 121 treatment sessions prospectively, and the children were randomized to either the presence of a female clown during treatment or to no presence of a clown. The duration of the child's crying during the procedure was used as an indicator of the effect of the presence of a clown.Results: The effect of the clown was significantly related to patient gender. Girls were found to have a significantly shorter period of crying when the clown was present. For children younger than 8 years, the effect on boys was negative. Children treated for the first time did not appear to benefit from the presence of the clown, and showed no difference in effect between genders.Conclusion: No effect of the clown was documented for children being treated for the first time. At repeat treatments, we saw a positive effect of the female clown in relation to girls, and a negative effect on boys younger than 8 years of age.Keywords: clown, injections, pain, botulinum toxin

    Full Text Available Purpose: To compare the efficiency of surgical procedures using three phaco tip designs in torsional phacoemulsification using the bevel-down technique. Methods: In this prospective, comparative, masked study, patients were randomly assigned to have torsional coaxial microincision cataract surgery using the mini-flared 45-degree Kelman tip, reversed mini-flared 30-degree Kelman tip, or Sidewinder 30-degree Kelman tip. Clinical measurements included preoperative and 3-month postoperative corrected distance visual acuity (CDVA, endothelial cell counts (ECC, and preoperative and 1-day postoperative central corneal thickness (CCT. Intraoperative measurements included phaco time, torsional time, aspiration time, case time, cumulative dissipated energy (CDE, and balanced salt solution volume (BSS. Results: The study evaluated 150 eyes of 150 patients. Intraoperatively, there was no statistically significant difference in cumulative dissipated energy, case time, torsional time, and aspiration time between the three tip configurations. However, less phaco time was used with the mini-flared 45-degree Kelman tip (p=0.02 than that with the Sidewinder 30-degree Kelman tip or reversed mini-flared 30-degree Kelman tip. The mini-flared 45-degree Kelman tip and the reversed mini-flared 30-degree Kelman tip required significantly less balanced salt solution volume than that required by the Sidewinder 30-degree Kelman tip (p=0.009. There was no statistically significant difference in corrected distance visual acuity and endothelial cell counts between tips 3 months postoperatively (p>0.05. Conclusion: All three tips were effective with no intraoperative complications. When using torsional phacoemulsification through microincisions and the prefracture technique with the bevel-down technique, the mini-flared 45-degree Kelman tip required a lower mean phaco time than the reversed mini-flared 30-degree Kelman tip and the Sidewinder 30-degree Kelman tip.

    To compare the efficiency of surgical procedures using three phaco tip designs in torsional phacoemulsification using the bevel-down technique. In this prospective, comparative, masked study, patients were randomly assigned to have torsional coaxial microincision cataract surgery using the mini-flared 45-degree Kelman tip, reversed mini-flared 30-degree Kelman tip, or Sidewinder 30-degree Kelman tip. Clinical measurements included preoperative and 3-month postoperative corrected distance visual acuity (CDVA), endothelial cell counts (ECC), and preoperative and 1-day postoperative central corneal thickness (CCT). Intraoperative measurements included phaco time, torsional time, aspiration time, case time, cumulative dissipated energy (CDE), and balanced salt solution volume (BSS). The study evaluated 150 eyes of 150 patients. Intraoperatively, there was no statistically significant difference in cumulative dissipated energy, case time, torsional time, and aspiration time between the three tip configurations. However, less phaco time was used with the mini-flared 45-degree Kelman tip (p=0.02) than that with the Sidewinder 30-degree Kelman tip or reversed mini-flared 30-degree Kelman tip. The mini-flared 45-degree Kelman tip and the reversed mini-flared 30-degree Kelman tip required significantly less balanced salt solution volume than that required by the Sidewinder 30-degree Kelman tip (p=0.009). There was no statistically significant difference in corrected distance visual acuity and endothelial cell counts between tips 3 months postoperatively (p>0.05). All three tips were effective with no intraoperative complications. When using torsional phacoemulsification through microincisions and the prefracture technique with the bevel-down technique, the mini-flared 45-degree Kelman tip required a lower mean phaco time than the reversed mini-flared 30-degree Kelman tip and the Sidewinder 30-degree Kelman tip.

    Full Text Available Background: A randomized, prospective clinical, radiographical, and histological study was conducted to evaluate healing after alveolar ridge preservation technique using two different graft materials, namely, a novel autogenous graft material i. e., autogenous tooth graft (ATG and beta-tricalcium phosphate (β-TCP alloplast. Materials and Methods: Fifteen patients undergoing extraction of at least three teeth were selected. Atraumatic extractions were performed. Of the three extraction sockets, one was grafted with ATG, other with β-TCP, and the third was left ungrafted. Cone-beam computed tomography scans were taken immediately after grafting and 4 months postoperatively to check the changes in alveolar crest height and width at all the sites. Three patients in whom implant placement was done after complete healing; bone samples were harvested using a 3 mm diameter trephine during osteotomy preparation from both the ridge preserved sites and studied histologically. Results: There was a statistically significant difference when the changes in width and height of alveolar crest were compared within all the three groups (P < 0.05. Among three sites, ATG-grafted sites showed the most superior results with a minimal reduction in alveolar crest height and width. Histological analysis also showed the same trend with more new bone formation at ATG-grafted sites as compared to β-TCP-grafted sites. Conclusion: Postextraction, ridge preservation leads to more predictable maintenance of alveolar ridge height and width. ATG as compared to β-TCP provided superior results. Based on this, we conclude that ATG material can serve as a better alternative to conventional bone graft materials.

    Hyperbaric oxygen therapy (HBOT) appears to enhance wound healing, increase bactericidal activity, and act synergistically with a number of antibiotics. The aim of this study was to evaluate the efficacy of HBOT as an adjunctive therapy in patients with hidradenitis suppurativa (HS) treated with a combination of systemic rifampicin and clindamycin. The study was a prospective, single-center, single-dose, open-label, randomized controlled clinical study of HBOT in patients with moderate to severe HS. Efficacy was measured by modified Sartorius score (SS), HS Severity Index (HSSI), Dermatology Life Quality Index (DLQI), and a visual analog scale (VAS) before treatment and after the completion of 4 and 10 weeks of treatment. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were also measured. Forty-three patients were enrolled in the study. More patients in the HBOT than in the control group showed a decrease of ≥50% from baseline parameters at week 10 for SS (100%), HSSI (100%), DLQI (95.5%), VAS (100%), ESR (100%), and CRP (72.7%). Clinically and statistically significant improvements from baseline were observed at 4 and 10 weeks in HSSI (P = 0.009 at both), SS (P = 0.021 at both), and DLQI (P = 0.044 at week 4, P = 0.009 at week 10). Adjunctive HBOT was considered to be effective in significantly improving antibiotic treatment of HS. The treatment was well tolerated, and no unexpected safety issues were identified.

    Due to a growing numbers of lateral fragility fractures of the femur and their high social costs the need to work out an effective strategy in order to find a better solution for these patients is warranted. From January 2010 to July 2011, we carried out a prospective randomized clinical study comparing the results of patients with femoral lateral fractures treated by nail and cephalic hydroxyapatite coated screws (study group including 27 patients) compared to the patients with the same fractures treated with nail and head standard screws (control group including 27 patients). We defined the two parts of the femoral neck as ROI 1 (under the head screw) and ROI 2 (above the femoral screw) on the AP view. The bone density of the two areas was calculated using DEXA at T0 (1st day post-surgery), at T1 (40th day post-surgery), at T2 (3 months later), at T3 (1 year later). The clinical-radiography evaluations were based on the Harris Hip Score (HHS), ADL test and x-ray views of the hip. As far as the bone mineral density average of ROI 1 and ROI 2 is concerned, we found a significant statistical increase at T1 and T3 in the study group, while it was not significant in the control group. We could account for this data through the higher mechanical stability of hydroxyapatite coated screws than standard screws. In fact, this material was responsible for improved implant osteointegration. Thanks to a 1 year follow-up we were able to demonstrate the implant utility associated with augmentation and the importance of densitometry exams such as easily repeatable and low cost diagnostics to prevent the onset of complications linked to screw loosening.

    Purpose To evaluate the effect of posture and repetition of filling cystometry on urodynamic parameters. Materials and Methods Seventy-one men with benign prostatic hyperplasia participated in a urodynamic study between September 2015 and August 2016 and were randomly assigned to a supine to supine (group SS, n=16), erect to erect (group EE, n=16), supine to erect (group SE, n=19) or erect to supine (group ES, n=20) group. The patients underwent filling cystometry twice. We evaluated the effect of posture and the effect of repetition on filling cystometric parameters. We also evaluated the correlation between overactive bladder (OAB) and detrusor overactivity (DO) and between maximum voided volume (MVV) and maximum cystometric capacity (MCC) for each posture and filling cystometry time. Results There was a decrease in bladder sensation and occurrence of DO, and an increase in bladder compliance and MCC in the supine posture group compared to that in the erect posture group. A more significant decrease in bladder sensation and occurrence of DO as well as an increase in MCC was seen during the second filling cystometry than the first one. The supine posture during first filling cystometry showed a better correlation between OAB and DO and between MVV and MCC than erect posture. Conclusions There were clear effects of posture and filling cystometry repetition on urodynamic parameters. The supine posture and repeated filling cystometry caused the bladder to be less sensitive and less overactive. The supine posture showed a better correlation to OAB symptoms than erect posture during first filling cystometry. PMID:28097266

    Music is commonly played in operating theaters. Some surgeons believe music reduces stress and operative time, while others think music is a distraction and should be avoided. There is limited published evidence evaluating the effects of music on surgical performance. The goal of this study is to evaluate the effect of music on simple wound closure. Plastic surgery residents were asked to perform layered closures on pigs' feet with and without their preferred music playing. Simple randomization was used to assign residents to the music playing first or music playing second group. The time to complete the repair was measured and repairs were graded by blinded faculty. Results were analyzed to determine significant differences in time to complete the task and quality of repair. Participants were retested in a second session with music played in the opposite order to evaluate consistency. Listening to preferred music decreased repair time by 8% for all plastic surgery residents (p = 0.009). Subgroup analysis demonstrated even more significant improvement in speed for senior residents (PGY 4-6), resulting in a 10% decrease in repair time (p = 0.006). The quality of repair was also better in the music group, at 3.3 versus 3.1 (p = 0.047). Retesting revealed results remained significant whether music was played first or second. Playing preferred music made plastic surgery residents faster in completing wound closure with a 10% improvement in senior residents. Music also improved quality of repair as judged by blinded faculty. Our study showed that music improves efficiency of wound closure, which may translate to healthcare cost savings. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    Full Text Available BACKGROUND Recurrent malignant pleural effusion and spontaneous pneumothorax can be treated by a procedure called pleurodesis by which the pleural space is obliterated. This can be done by surgical means using mechanical force or by introducing any one of the recommended agents into the pleural space via tube thoracostomy or during thoracoscopy. Examples of agents used are talc as powder or as slurry, tetracycline derivatives, antineoplastic agents (Bleomycin, mitoxantrone, quinacrine, silver nitrate, Corynebacterium parvum and iodopovidone. The aim of the present study was to evaluate the safety and efficacy of iodopovidone as a sclerosing agent in the treatment of recurrent pleural effusion and spontaneous pneumothorax. This was a randomized prospective interventional study comparing iodopovidone with oxytetracycline as the latter is now sparingly available for clinical use. MATERIAL AND METHODS Study was conducted in 44 patients above 12 years of age, admitted in the Dept. of Pulmonary Medicine, Goa Medical College. Patients with a diagnosis of spontaneous pneumothorax or recurrent malignant pleural effusion were randomly allocated to either iodopovidone or oxytetracycline group and pleurodesis was done as per British Thoracic Society Guidelines (BTS. 1 RESULTS Among 44 patients 23 were secondary spontaneous pneumothorax, 9 were primary spontaneous pneumothorax and 12 were malignant pleural effusion; 2 patients did not report for follow-up visits and the remaining 42 patients were followed up for 6 months. The success rate of oxytetracycline and iodopovidone pleurodesis is 81% and 95.2% respectively. All the patients had chest pain of varying severity during the procedure in either groups; 8 patients in oxytetracycline group and 6 patients in iodopovidone group had fever after the procedure; 2 patients in iodopovidone group developed hypotension after the procedure and there was no mortality in either group attributable to the procedure

    Background and purpose: To compare the efficacy of two different dose-fractionation schedules for radiotherapy of patients with benign painful shoulder syndrome. Patients and methods: Between February 2006 and February 2010, 312 consecutive evaluable patients were recruited for this prospective randomized trial. All patients received radiotherapy with an orthovoltage technique. One radiotherapy course consisted of 6 single fractions in 3 weeks. In case of insufficient remission of pain after 6 weeks, a second radiation series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. The endpoint was pain reduction. Pain was measured before, right after, and 6 weeks after radiotherapy using a visual analogue scale (VAS) and a comprehensive pain score (CPS). Results: The overall response rate for all patients was 83% directly after and 85% 6 weeks after radiotherapy. The mean VAS values before, directly after, and 6 weeks after treatment for the 0.5 and 1.0 Gy groups were 56.8 {+-} 23.7 and 53.2 {+-} 21.8 (p = 0.158), 38.2 {+-} 26.1 and 34.0 {+-} 24.5 (p = 0.189), and 33.0 {+-} 27.2 and 23.7 {+-} 22.7 (p = 0.044), respectively. The mean CPS before, directly after, and 6 weeks after treatment was 9.7 {+-} 3.0 and 9.5 {+-} 2.7 (p = 0.309), 6.1 {+-} 3.6 and 5.4 {+-} 3.6 (p = 0.096), 5.3 {+-} 3.7 and 4.1 {+-} 3.7 (p = 0.052), respectively. Despite a slight advantage in the VAS analysis for the 1.0 Gy group for delayed response, the CPS analysis revealed no statistically significant differences between the two single-dose trial arms for early (p = 0.652) and delayed response quality (p = 0.380). Conclusion: Radiotherapy is an effective treatment option for the management of benign painful shoulder syndrome. Concerning radiation protection, the dose for a radiotherapy series is recommended not to exceed 3-6 Gy. (orig.)

    Background Tradition treatment of sepsis and new therapies, including high dose corticosteroids and non-steroidal anti-inflammatory drugs, have proven unsuccessful in improving survival. This study aimed to evaluate the potential efficacy of immunomodulating therapy using Ulinastatin (UTI) plus Thymosin α1 (Tα1) for improving organ function and reducing mortality in patients with severe sepsis.Methods A prospective study was carried out with randomized and controlled clinical analysis of 114 patients conforming to the enrollment standard. All patients had severe sepsis and received standard supportive care and antimicrobial therapy. Fifty-nine patients were also administered UTI plus Tα1 (defined as Group A), 55 patients were given a placebo (defined as Group B). Clinical parameters were determined by evaluation with the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ), multiple organ failure (MOF) and the Glasgow Coma Scores (GCS) on entry and after therapy on the 3rd, 8th, and 28th day. By flow cytometery and ELISA lymphocyte subsets and cytokines were analyzed. Survival analysis was determined by the Kaplan-Meier method at 28, 60, and 90 days. Results Based on comparison of the two groups, patients in Group A exhibited a better performance in organ failure scores which was noticeable soon after initiation of treatment. Patients in Group A also demonstrated a better resolution of pre-existing organ failures during the observation period. After initiation of treatment, significant improvements in the CD4+/CD8+ ratio, a quicker balance between proinflammatory mediators such as tumor necrosis factor a, interleukin 6 and anti-inflammatory cytokines including interleukin 4 and interleukin 10 were found. This was followed by cumulative survival increases of 17.3% at 28 days, 28.9% at 60 days, and 31.4% at 90 days in Group A. The reduction in mortality was accompanied by a considerably shorter stay in the ICU and a shorter length of supportive

    To evaluate the effect of listening to music on pain, anxiety, and success of procedure during office-based percutaneous nephrostomy tube placement (PNTP). One hundred consecutive patients (age >18 years) with hydronephrosis were prospectively enrolled in this study. All patients were prospectively randomized to undergo office-based PNTP with (Group I, n = 50) or without music (Group II, n = 50). Anxiety levels were evaluated with State Trait Anxiety Inventory. A visual analog scale was used to evaluate pain levels, patient's satisfaction, and willingness to undergo the procedure. We also compared success rates of procedures. The mean age, duration of procedure, and gender distribution were statistically similar between the two groups. The mean postprocedural heart rates and systolic blood pressures in Group I patients were significantly lower than Group II patients (p = 0.01 and p = 0.028, respectively), whereas preprocedural pulse rate and systolic blood pressure were similar. The mean anxiety level and mean pain score of Group I were significantly lower than those of Group II (p = 0.008 and p music during office-based PNTP decreases anxiety or pain and increases success rate of procedure. As an alternative to sedation or general anesthesia, music is easily accessible without side effect and cost.

    In this study, we compared the clinical efficacy of JOINS (SKI306X, SK Chemicals) with placebo on cartilage protection using magnetic resonance imaging (MRI). Sixty-nine patients were randomized to the JOINS group (200 mg, three times daily for 1 year; n=33) or the placebo group (n=36). Changes in cartilage volume and thickness were measured using MRI. Changes in the delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) index, subchondral bone marrow abnormality scores, and clinical scores including knee pain visual analog scale (VAS) score and Korean Western Ontario and McMaster Universities Osteoarthritis Index (K-WOMAC) were also evaluated. Changes in cartilage thickness and volume and subarticular bone marrow abnormality scores were not different between groups. Changes in the dGEMRIC index in the lateral tibial plateau were greater in the JOINS group than in the placebo group (19.64±114.33 msec vs. -57.77±123.30 msec; p=0.011). Significantly greater changes in VAS were observed in the JOINS group than in the placebo group (-26.00±12.25 vs. -12.47±21.54; p=0.002) and K-WOMAC (-15.42 ± 7.73 vs. -8.15±13.71; p=0.003). Compared with placebo, JOINS had superior clinical efficacy in regard to cartilage protection.

    Full Text Available OBJECTIVE: This trial has the objective to investigate the incidence of mechanical ankle instability after the conservative treatment of first episode, severe ankle ligamentar lesions. This common lesion affects young, professional and physical active patients, causing important personal and economic consequences. There are difficulties related to adequate diagnosis and treatment for these lesions. METHOD: 186 patients with severe ankle ligament lesions were included in this trial. They were randomized in two treatment options. In group A patients were treated using ankle long orthoosis, weight bearing allowed as confortable, pain care, ice, elevation with restricted joint mobilization for three weeks. After that they were maintained in short, functional orthosis (air cast, starting the reabilitation program. In group B patients were immobilized using a functional orthosis (air cast, following the same other sequences that patients in group A. RESULTS: We did not find significant differences in relation to the residual mechanical ankle instability between both groups. We did not find differences in the intensity of pain, but the functional evaluation using AOFAS score system showed better results in the functional treatment group. CONCLUSION: The functional treatment (Group B had better AOFAS score and few days off their professional activities, comparing with patients treated with rigid orthosis (Group A, without increased chance in developing ankle mechanical instability.

    Full Text Available We have established a novel method named transumbilical two-port laparoscopic varicocele ligation (TTLVL for varicocele, which is still needed to evaluate. In this study, 90 patients with left idiopathic symptomatic varicoceles of grades II-III according to the Dubin grading system were randomly assigned to TTLVL (n = 45 and conventional laparoscopic varicocele ligation (CLVL (n = 45. The demographic, intraoperative, postoperative, and follow-up data were recorded and compared between the two groups. All the procedures in the two groups were completed successfully with no intraoperative complications and no conversions to open surgery. No significant difference was found in the operative time, resuming ambulation, bowel recovery, postoperative hospital stay, and postoperative resolution of scrotal pain between the two groups (P > 0.05. However, the postoperative mean visual analog pain scale scores for TTLVL group were all less at 24 h, 48 h, 72 h, and 7 days postoperatively compared to CLVL (P = 0.001, 0.010, 0.006, and 0.027, respectively. The mean patient scar assessment questionnaire score in postoperative month 3 was 29.7 for TTLVL group compared with 32.1 for CLVL group (P < 0.001. There was no testicular atrophy observed in both groups during the follow-up period. The study shows that TTLVL is a safe, feasible, and effective minimally invasive surgical alternative to CLVL for the treatment of varicocele. Compared with CLVL, TTLVL may decrease postoperative pain and improve the cosmetic outcomes.

    Magnetic resonance imaging has been recognized for years as the safest and most precise imaging method, particularly for children. The accuracy of MRI depends on avoidance of patient movement during the study. This may be difficult for children and may require anesthesia. We evaluated an introductory instruction program as an assistive tool in performing MRI without anesthesia. In one institution, 121 children were randomized to undergo full interactive pre-MRI instruction (n=64), which included an instructional booklet, movie and simulator practice, or partial instruction (n=57), comprised of the booklet only. All researchers and health care professionals involved, except for the one who instructed the families, were masked to the group allocation. Parents' anxiety, according to the Spielberger state anxiety inventory, was measured. Median age was 7.4 years (range: 5 years-16 years). Anesthesia was required for fewer children who received full compared to partial instruction: 17 (27%) vs. 27 (47%), P≤0.02. The median anxiety level prior to instruction was higher than the median level after instruction, for both the partial and full instruction groups. Instruction including simulator practice was associated with a decreased need for anesthesia among children undergoing MRI scans. (orig.)

    We have established a novel method named transumbilical two-port laparoscopic varicocele ligation (TTLVL) for varicocele, which is still needed to evaluate. In this study, 90 patients with left idiopathic symptomatic varicoceles of grades II–III according to the Dubin grading system were randomly assigned to TTLVL (n = 45) and conventional laparoscopic varicocele ligation (CLVL) (n = 45). The demographic, intraoperative, postoperative, and follow-up data were recorded and compared between the two groups. All the procedures in the two groups were completed successfully with no intraoperative complications and no conversions to open surgery. No significant difference was found in the operative time, resuming ambulation, bowel recovery, postoperative hospital stay, and postoperative resolution of scrotal pain between the two groups (P > 0.05). However, the postoperative mean visual analog pain scale scores for TTLVL group were all less at 24 h, 48 h, 72 h, and 7 days postoperatively compared to CLVL (P = 0.001, 0.010, 0.006, and 0.027, respectively). The mean patient scar assessment questionnaire score in postoperative month 3 was 29.7 for TTLVL group compared with 32.1 for CLVL group (P < 0.001). There was no testicular atrophy observed in both groups during the follow-up period. The study shows that TTLVL is a safe, feasible, and effective minimally invasive surgical alternative to CLVL for the treatment of varicocele. Compared with CLVL, TTLVL may decrease postoperative pain and improve the cosmetic outcomes. PMID:26732104

    The purpose of our study was to determine the safety and tolerability of early oral hydration (EOH) compared with delayed oral hydration (DOH) after general anesthesia. One thousand anesthesiology (ASA) I to III adult patients undergoing non-gastrointestinal surgery with general anesthesia were randomized assigned into two groups: DOH (n=500, patients were given water 4 h after general anesthesia), EOH (n=500, patients were given 0.5 ml/kg water once recovered from general anesthesia.) in the postanesthesia care unit (PACU). Patients were evaluated for nausea, vomiting, drink desire, thirsty scale, oropharyngeal discomfort scale, and satisfaction scale. Statistical analysis was performed with Student’s t and Chi-Square tests. Complete data were available for 983 patients (EOH=488, DOH=495). Twenty minutes after receiving water the incidence of vomiting in EOH group was very low. And there was no significant difference between the two groups at the same time point (p > 0.05). Compared with DOH group, after receiving water there was a significant decrease of patients’ thirsty scales (p < 0.0001) and oropharyngeal discomfort scales (p < 0.0001) in EOH group. Significantly more patients’ satisfaction were reported in EOH group (p < 0.001). No serious adverse effects were reported during the study period. For patients undergoing non-gastrointestinal surgery, early oral hydration after recovery from general anesthesia was safe, with lower thirsty scale and oropharyngeal discomfort scales, and higher satisfaction.

    Patients who undergo endoscopic biopsy suffer anxiety until results are confirmed. This study assesses the effects of written educational material on the anxiety level of patients following endoscopic biopsy. This study was a randomized controlled study trial with 83 patients divided into the following three groups: a biopsy group given written educational material prepared by our institution following the biopsy (intervention group, n=28), a biopsy group without written material (biopsy only group, n=25), and a control group without biopsy (control group, n=30). The anxiety level of each patient was evaluated three times using Spielberger's State-Trait Anxiety Inventory (STAI): for baseline at the first visit to our institution, at the day of endoscopy, one day later, and one week after the procedure. We compared baseline characteristics, STAI scores at each visit, and differences in STAI scores among the three groups. No difference was found in STAI score among groups at baseline and before and after the endoscopic procedure. However, the STAI-state score of the intervention group was slightly lower than biopsy only group one day post-procedure (40.3 ± 7.7 vs. 43.9 ± 7.1, p=0.135). The STAI-state score significantly decreased from pre- to post-procedure only in the intervention group (-2.75 ± 6.1 vs. 0.92 ± 4.0, pmaterial for patients having biopsy might lessen their anxiety level.

    Postpartum hemorrhage is the single largest and leading cause of maternal morbidity and mortality not only in developing countries but also in developed countries. The present study is an attempt to evaluate the scope of using prophylactic intramuscular carboprost tromethamine 125 μg in comparison with intramuscular oxytocin 10 units for the active management of third stage of labor. Two hundred pregnant women at term with spontaneous onset of labor were included in the study and were randomly divided into 2 groups of 100 women each. Group A and group B were given injection oxytocin 10 units and injection carboprost tromethamine 125 μg intramuscularly, respectively, at the time of delivery of anterior shoulder. The main outcome measures with respect to third stage of labor were: duration, blood loss by volume, difference in hemoglobin, need for additional oxytocics and side effects. Subjects who received carboprost tromethamine 125 μg showed a significant reduction in duration of third stage of labor (p oxytocin 10 units. Likelihood of occurrence of postpartum hemorrhage was reduced without significant side effects except for diarrhea. Additional need for other uterotonics after carboprost was significantly less compared to oxytocin. Intramuscular carboprost 125 μg is a better cost-effective alternative as compared to 10 units intramuscular oxytocin in active management of third stage of labor.

    There is some controversy about the value of sentinel lymph node excision (SLNE) in patients with head and neck malignancies. The gold standard for detection and targeted extirpation of the SLN is lymphoscintigraphy with {sup 99m}Tc-nanocolloid. The purpose of this prospective randomized study was to analyse the feasibility and clinical benefit of a hybrid tracer comprising the near-infrared (NIR) fluorescent indocyanine green (ICG) and {sup 99m}Tc-nanocolloid (ICG-{sup 99m}Tc-nanocolloid) in direct comparison with standard {sup 99m}Tc-nanocolloid for guiding SLNE in patients with head and neck cutaneous malignancies. We analysed the data from 40 clinically lymph node-negative patients with melanoma, high-risk cutaneous squamous cell carcinoma, Merkel cell carcinoma or sweat gland carcinoma who underwent SLNE with ICG-{sup 99m}Tc-nanocolloid (cohort A) or with the standard {sup 99m}Tc-nanocolloid (cohort B). Overall SLNs were identified preoperatively in all 20 patients (100 %) in cohort A and in 18 of 20 patients (90 %) in cohort B. The SLN basin was detected preoperatively in 18 patients (90 %) in cohort A and also in 18 patients (90 %) in cohort B. SLNs were identified intraoperatively in all 20 patients (100 %) in cohort A and in 19 patients (95 %) in cohort B (p = 0.487). Metastatic SLNs were detected in 9 patients (22.5 %), 3 (15.0 %) in cohort A and 6 (30.0 %) in cohort B (p = 0.228). The hybrid tracer ICG-{sup 99m}Tc-nanocolloid is an innovative imaging tracer, reliably and readily providing additional information for the detection and excision of SLN in the head and neck region. Therefore, SLNE with combined radioactive and NIR fluorescence guidance is an attractive option for improving the SLN detection rate in patients with cutaneous head and neck malignancies. (orig.)

    Purpose: To determine outcomes of accelerated partial-breast irradiation (APBI) with MammoSite in the treatment of ductal carcinoma in situ (DCIS) after breast-conserving surgery. Methods and Materials: We conducted a prospective, multicenter trial between 2003 and 2009. Inclusion criteria included age >18 years, core needle biopsy diagnosis of DCIS, and no prior breast cancer history. Patients underwent breast-conserving surgery plus MammoSite placement. Radiation was given twice daily for 5 days for a total of 34 Gy. Patients were evaluated for development of toxicities, cosmetic outcome, and ipsilateral breast tumor recurrence (IBTR). Results: A total of 41 patients (42 breasts) completed treatment in the study, with a median follow up of 5.3 years. Overall, 28 patients (68.3%) experienced an adverse event. Skin changes and pain were the most common adverse events. Cosmetic outcome at 6 months was judged excellent/good by 100% of physicians and by 96.8% of patients. At 12 months, 86.7% of physicians and 92.3% of patients rated the cosmetic outcome as excellent/good. Overall, 4 patients (9.8%) developed an IBTR (all DCIS), with a 5-year actuarial rate of 11.3%. All IBTRs were outside the treatment field. Among patients with IBTRs, the mean time to recurrence was 3.2 years. Conclusions: Accelerated partial-breast irradiation using MammoSite seems to provide a safe and cosmetically acceptable outcome; however, the 9.8% IBTR rate with median follow-up of 5.3 years is concerning. Prospective randomized trials are necessary before routine use of APBI for DCIS can be recommended.

    Objective To compare the effectiveness of shared decision making with usual care in choice of admission for observation and further cardiac testing or for referral for outpatient evaluation in patients with possible acute coronary syndrome. Design Multicenter pragmatic parallel randomized controlled trial. Setting Six emergency departments in the United States. Participants 898 adults (aged >17 years) with a primary complaint of chest pain who were being considered for admission to an observation unit for cardiac testing (451 were allocated to the decision aid and 447 to usual care), and 361 emergency clinicians (emergency physicians, nurse practitioners, and physician assistants) caring for patients with chest pain. Interventions Patients were randomly assigned (1:1) by an electronic, web based system to shared decision making facilitated by a decision aid or to usual care. The primary outcome, selected by patient and caregiver advisers, was patient knowledge of their risk for acute coronary syndrome and options for care; secondary outcomes were involvement in the decision to be admitted, proportion of patients admitted for cardiac testing, and the 30 day rate of major adverse cardiac events. Results Compared with the usual care arm, patients in the decision aid arm had greater knowledge of their risk for acute coronary syndrome and options for care (questions correct: decision aid, 4.2 v usual care, 3.6; mean difference 0.66, 95% confidence interval 0.46 to 0.86), were more involved in the decision (observing patient involvement scores: decision aid, 18.3 v usual care, 7.9; 10.3, 9.1 to 11.5), and less frequently decided with their clinician to be admitted for cardiac testing (decision aid, 37% v usual care, 52%; absolute difference 15%; P<0.001). There were no major adverse cardiac events due to the intervention. Conclusions Use of a decision aid in patients at low risk for acute coronary syndrome increased patient knowledge about their risk, increased

    A randomized double-blind prospective study of pulsed electromagnetic fields for lumbar interbody fusions was performed on 195 subjects. There were 98 subjects in the active group and 97 subjects in the placebo group. A brace containing equipment to induce an electromagnetic field was applied to patients undergoing interbody fusion in the active group, and a sham brace was used in the control group. In the active group there was a 92% success rate, while the control group had a 65% success rate (P greater than 0.005). The effectiveness of bone graft stimulation with the device is thus established.

    Full Text Available Multiaxial fatigue is a very important physical phenomenon to take into account in several mechanical components; its study is of utmost importance to avoid unexpected failure of equipment, vehicles or structures. Among several fatigue characterization tools, a correct definition of a damage parameter and a load cycle counting method under multiaxial loading conditions show to be crucial to estimate multiaxial fatigue life. In this paper, the SSF equivalent stress and the virtual cycle counting method are presented and discussed, regarding their physical foundations and their capability to characterize multiaxial fatigue damage under complex loading blocks. Moreover, it is presented their applicability to evaluate random fatigue damage.

    AIM: To compare the effectiveness, patient acceptability, and physical tolerability of two oral lavage solutions prior to colonoscopy in a Taiwanese population. METHODS: Eighty consecutive patients were randomized to receive either standard 4 L of polyethylene glycol (PEG) or 90 mL of sodium phosphate (NaP) in a split regimen of two 45 mL doses separated by 12 h, prior to colonoscopic evaluation. The primary endpoint was the percent of subjects who had completed the preparation. Secondary endpoints included colonic cleansing evaluated with an overall assessment and segmental evaluation, the tolerance and acceptability assessed by a selfadministered structured questionnaire, and a safety profile such as any unexpected adverse events, electrolyte tests, physical exams, vital signs, and body weights. RESULTS: A significantly higher completion rate was found in the NaP group compared to the PEG group(84.2% vs 27.5%, P<0.001). The amount of fluid suctioned was significantly less in patients taking NaP vs PEG (50.13±54.8 cc vs 121.13±115.4 cc, P<0.001),even after controlling for completion of the oral solution(P = 0.031). The two groups showed a comparable overall assessment of bowel preparation with a rate of "good" or "excellent" in 78.9% of patients in the NaPgroup and 82.5% in PEG group (P = 0.778). Patients taking NaP tended to have significantly better colonic segmental cleansing relative to stool amount observedin the descending (94.7% vs 70%, P = 0.007) andtransverse (94.6% vs 74.4%, P = 0.025) colon. Slightly more patients graded the taste of NaP as "good" or "very good" compared to the PEG patients (32.5% vs 12.5%;P = 0.059). Patients' willingness to take the same preparation in the future was 68.4% in the NaP compared to 75% in the PEG group (P = 0.617). There was a significant increase in serum sodium and a significant decrease in phosphate and chloride levels in NaP group on the day following the colonoscopy without any clinical sequelae.

    An open, prospective, randomized study was performed to investigate the effect of norfloxacin prophylaxis on stricture formation and operative outcome after transurethral resection of the prostate. After resection, the 359 patients studied were randomly divided into 2 groups: 1) those given norfloxacin as prophylaxis for 15 days following removal of the catheter (norfloxacin group) and 2) those given no antimicrobial prophylaxis during the same period (control group). Of the patients 94 were excluded. At followup 6 to 12 months postoperatively, the number of strictures in the anterior urethra was 2 of 135 in the norfloxacin group and 22 of 130 in the control group (p norfloxacin group, fewer patients in that group were dissatisfied with the operative outcome. The results suggest that norfloxacin provides effective prophylaxis against stricture formation after transurethral resection of the prostate.

    We performed a randomized, prospective study to assess the effectiveness of postoperative cold therapy in patients who had anterior cruciate ligament reconstructions. Drain output, length of hospital stay, range of motion, and use of pain medication were all assessed. Patients were randomized into one of four groups after surgery. Group 1 patients had a cooling pad applied to the knee postoperatively and set at a temperature of 40 degrees to 50 degrees F, Group 2 had the cooling pad set at 70 degrees to 80 degrees F, Group 3 received ice packs, and Group 4 received no cold therapy of any kind. The skin temperatures in Groups 1 and 3 were significantly lower than the skin temperatures in Groups 2 and 4 (P cold therapy were seen in any group. Thus, both ice packs and cooling pads significantly decreased knee temperature, but we found no objective benefits in the early postoperative course due to this decrease in temperature.

    This study compared the efficacy and patient acceptability of two methods of bowel preparation for flexible sigmoidoscopy. Patients attending for outpatient flexible sigmoidoscopy were prospectively randomized to receive one Fleet ready-to-use enema or 2 x 4 g glycerin suppositories, 2 h preprocedure. Patient and endoscopist questionnaires were used to compare the outcomes. From November 2000 to August 2001, 203 (male = 95; female = 108) patients were randomized. Patient data available for 163 patients (enema = 93; suppository = 70) revealed: ease of use (enema = 52; suppository = 25; P suppository = 3; P suppository = 44; P suppository = 24; P = 0.016, Fisher's exact). Endoscopist data available for 151 patients (enema = 76; suppository = 75) revealed: average depth of insertion (enema = 53.6 +/- 11.6 cm; suppository 46.3 +/- 13.7 cm; P suppository = 34 (45.3%); P suppositories.

    An anal fissure (AF) is a tear in the epithelial lining of the anal canal. This is a very common condition, but the choice of treatment is unclear. The use of anal dilators is effective, economic, and safe. The aim of the study was to compare the efficacy of two conservative treatments, the use of anal dilators or a finger for anal dilatation, in reducing anal pressure and resolving anal fissures. Fifty patients with a clinical diagnosis of AF were randomly assigned to one of the treatments, self-massage of the anal sphincter (group A, 25 patients) or passive dilatation using dilators (group B, 25 patients). All patients were evaluated at baseline, at the end of treatment, and after 12 weeks and 6 months. Pain was measured using a visual analog scale. After the treatment, 60% of patients treated with dilators and 80% of patients treated with anal self-massage using a finger showed disappearance of their anal fissures. A comparison between signs and symptoms reported by the patients in the two groups showed a statistically significant reduction in anal pain (group A, P=0.0001; group B, P=0.0001) and bleeding after defecation (group A, P=0.001, group B, P=0.001). At 6 months after treatment, a significantly greater reduction in anal pain was observed in Group A compared to Group B (P=0.02). The use of anal self-massage with a finger appears to induce a better resolution of acute anal fissure than do anal dilators, and in a shorter time.

    To evaluate and compare the clinical retention of a resin-based fissure sealant placed with an intermediate layer of etch-and-rinse (ER) or self-etch (SE) adhesives. Two hundred twenty-eight sealants were placed in 57 children with previously unsealed, caries-free permanent first molars, employing a split-mouth design. The teeth were randomized into four groups (n = 57 teeth/groups) according to the adhesive system placed under the tested sealant (Delton FS+; Dentsply). Group 1 (control): no bonding agent (conventional acid-etch sealant); group 2: prior enamel etch + ER adhesive (XP Bond; Dentsply); group 3: SE adhesive (Clearfil SE Bond; Kuraray) without prior etching; and group 4: prior enamel etch + SE adhesive (Clearfil SE Bond). Clinical assessments were performed according to modified USPHS criteria at 1, 3, 6, 12, 18, and 24 months. The data were analyzed statistically using Fisher's Exact test, the Kaplan-Meier analysis, and the Log-rank test. At 24 months, sealants bonded with XP Bond and Clearfil SE Bond with prior enamel etching showed similar retention rates (p > 0.05), and these rates were significantly better than the rates of the conventional sealant and Clearfil-SE groups (p  0.05). The cumulative survival rates on palatal/buccal surfaces showed similar outcomes as with occlusal surfaces: XP Bond (94%), Clearfil SE Bond + acid-etch (94%), conventional sealant (52%), and Clearfil SE Bond only (37%). Application of the tested ER adhesive and the SE adhesive with enamel etching significantly improved the clinical retention of Delton-FS over the 24-month period. The use of a resin-based fissure sealant placed with ER or SE adhesive with prior acid-etching yielded better retention than the conventional sealant over the 24-month period.

    2012-09-01

    Full Text Available The objective of this study was to compare different random regression models, defined from different classes of heterogeneity of variance combined with different Legendre polynomial orders for the estimate of (covariance of quails. The data came from 28,076 observations of 4,507 female meat quails of the LF1 lineage. Quail body weights were determined at birth and 1, 14, 21, 28, 35 and 42 days of age. Six different classes of residual variance were fitted to Legendre polynomial functions (orders ranging from 2 to 6 to determine which model had the best fit to describe the (covariance structures as a function of time. According to the evaluated criteria (AIC, BIC and LRT, the model with six classes of residual variances and of sixth-order Legendre polynomial was the best fit. The estimated additive genetic variance increased from birth to 28 days of age, and dropped slightly from 35 to 42 days. The heritability estimates decreased along the growth curve and changed from 0.51 (1 day to 0.16 (42 days. Animal genetic and permanent environmental correlation estimates between weights and age classes were always high and positive, except for birth weight. The sixth order Legendre polynomial, along with the residual variance divided into six classes was the best fit for the growth rate curve of meat quails; therefore, they should be considered for breeding evaluation processes by random regression models.

    Background Observational studies examining associations between adult height and risk of colorectal, prostate, and lung cancers have generated mixed results. We conducted meta-analyses using data from prospective cohort studies and further carried out Mendelian randomization analyses, using height-associated genetic variants identified in a genome-wide association study (GWAS), to evaluate the association of adult height with these cancers. Methods and Findings A systematic review of prospective studies was conducted using the PubMed, Embase, and Web of Science databases. Using meta-analyses, results obtained from 62 studies were summarized for the association of a 10-cm increase in height with cancer risk. Mendelian randomization analyses were conducted using summary statistics obtained for 423 genetic variants identified from a recent GWAS of adult height and from a cancer genetics consortium study of multiple cancers that included 47,800 cases and 81,353 controls. For a 10-cm increase in height, the summary relative risks derived from the meta-analyses of prospective studies were 1.12 (95% CI 1.10, 1.15), 1.07 (95% CI 1.05, 1.10), and 1.06 (95% CI 1.02, 1.11) for colorectal, prostate, and lung cancers, respectively. Mendelian randomization analyses showed increased risks of colorectal (odds ratio [OR] = 1.58, 95% CI 1.14, 2.18) and lung cancer (OR = 1.10, 95% CI 1.00, 1.22) associated with each 10-cm increase in genetically predicted height. No association was observed for prostate cancer (OR = 1.03, 95% CI 0.92, 1.15). Our meta-analysis was limited to published studies. The sample size for the Mendelian randomization analysis of colorectal cancer was relatively small, thus affecting the precision of the point estimate. Conclusions Our study provides evidence for a potential causal association of adult height with the risk of colorectal and lung cancers and suggests that certain genetic factors and biological pathways affecting adult height may also affect the

    To compare the outcome of tension-band wiring (TBW) with the cable pin system (CPS) for transverse fractures of the patella. Randomized prospective study. Academic Level I trauma center. From February 2008 to December 2011, 73 consecutive patients with transverse fractures of the patella were prospectively enrolled in this study. The patients were randomly divided into 2 groups: one group was treated using the CPS, and the other group was treated using the modified TBW. The clinical outcome assessment included analyses of the radiographic images, the modified Hospital for Special Surgery scoring system, and complications. The follow-up time ranged from 12 to 29 months. All fractures healed, with a union rate of 100%. The fracture healing time was significantly shorter in the CPS group (8.51 ± 2.59 weeks, n = 34) compared with the TBW group (11.79 ± 3.04 weeks, n = 39). Postoperative complications in the CPS and TBW groups were observed in 1 and 9 patients, respectively, a difference that was statistically significant. The mean Hospital for Special Surgery score for the CPS group (90.53 ± 5.19 points) was significantly higher than that for the TBW group (81.36 ± 12.71 points). The CPS is a viable option for transverse fractures of the patella and is associated with a shorter healing time, fewer complications, and better function than TBW. Therapeutic Level I.

    Full Text Available Background: Hysteroscopy is the gold standard procedure for uterine cavity exploration. However, hysteroscopy is only recommended by the WHO when clinical or complementary exams (ultrasound, HSG suggest intrauterine abnormality or after in vitro fertilization failure. Nevertheless, many specialists feel that hysteroscopy is a more accurate tool. The aim of this prospective study is to assess the value of diagnostic hysteroscopy in a primary workup of infertility by describing hysteroscopy findings in a population of 324 infertile patients during 18 months (December 2010 - May 2012. Methods: We analysed prospectively 324 infertile patients in gynaecology OT setting. Diagnostic video-assisted hysteroscopy was performed using a flexible hysteroscope. Hysteroscopy was performed with a standard sequence, inspecting the endocervical canal, uterine cavity, endometrium, and tubal ostia and findings recorded. Results: Hysteroscopy was normal in 65.12% of patients. Cervico-isthmic abnormalities were present in 6.48% of patients with cervical stenosis being the major abnormality. Uterine cavity was normal in 86% of patients. Observed abnormalities were septate uterus in 10 cases, intrauterine synechiae in 16 cases, sub mucus myoma in 2 cases, deformed cavity in 10 cases and endometrial polyp in 2 cases. Ostial fibrosis was observed in 29 patients. Endometrial abnormalities (fibrosis, inflammation were observed in 30 patients. Seven patients turned out to be of genital tuberculosis with endometrial biopsy. No significance was found regarding the total number of intrauterine pathologies when comparing the groups of primary versus secondary infertility. Conclusions: Rates of abnormal findings in infertile patient who underwent diagnostic hysteroscopy was 34.88% in our study. Our data are an additional argument to suggest hysteroscopy as part of investigation in infertile woman. Routine diagnostic hysteroscopy should be part of an infertility workup in primary

    The effect of using gamma irradiation to sterilize bone-patellar tendon-bone (BPTB) allograft on the clinical outcomes of anterior cruciate ligament (ACL) reconstruction with irradiated allograft remains controversial. Our study was aimed to analyze the clinical outcomes of arthroscopic ACL reconstruction with irradiated BPTB allograft compared with non-irradiated allograft and autograft. All BPTB allografts were obtained from a single tissue bank and the irradiated allografts were sterilized with 2.5 Mrad of irradiation prior to distribution. A total of 102 patients undergoing arthroscopic ACL reconstruction were prospectively randomized consecutively into three groups. The same surgical technique was used in all operations done by the same senior surgeon. Before surgery and at the average of 31 months follow-up (range 24-47 months) patients were evaluated by the same observer according to objective and subjective clinical evaluations. Of these patients, 99 (autograft 33, non-irradiated allograft 34, irradiated allograft 32) were available for full evaluation. When compared the irradiated allograft group to non-irradiated allograft group or autograft group at 31 months follow-up by the Lachman test, ADT, pivot shift test and KT-2000 arthrometer testing, statistically significant differences were found. Most importantly, 87.8% of patients in the Auto group, 85.3% in the Non-Ir-Auto group and just only 31.3% in the Ir-Allo group had a side-to-side difference of less than 3 mm according to KT-2000. The failure rate of the ACL reconstruction with irradiated allograft (34.4%) was higher than that with autograft (6.1%) and non-irradiated allograft (8.8%). The anterior and rotational stability decreased significantly in the irradiated allograft group. According to the overall IKDC, functional, subjective evaluations and activity level testing, no statistically significant differences were found between the three groups. However, there was a trend that the functional and

    Umezawa, Yasushi; Mori, Hiroyuki

    A new method is proposed for credit risk evaluation in a power market. The credit risk evaluation is to measure the bankruptcy risk of the company. The power system liberalization results in new environment that puts emphasis on the profit maximization and the risk minimization. There is a high probability that the electricity transaction causes a risk between companies. So, power market players are concerned with the risk minimization. As a management strategy, a risk index is requested to evaluate the worth of the business partner. This paper proposes a new method for evaluating the credit risk with Random Forest (RF) that makes ensemble learning for the decision tree. RF is one of efficient data mining technique in clustering data and extracting relationship between input and output data. In addition, the method of generating pseudo-measurements is proposed to improve the performance of RF. The proposed method is successfully applied to real financial data of energy utilities in the power market. A comparison is made between the proposed and the conventional methods.

    Full Text Available Summative evaluation is evaluation done after software design and production is complete in order to establish its performance and properties. A prototypical case would be the tables produced in the consumer magazine Which? comparing a considerable range of properties of alternative available products (for example, washing machines that they have measured in their own trials. Thus summative evaluation is not only done after production; it is typically about comparative measurements done to assist decisions concerning purchase.

    Continuing education of health professionals is important for delivery of quality health care. Surgical nurses are often required to understand surgical procedures. Nurses need to be aware of the expected outcomes and recognize potential complications of such procedures during their daily work. Traditional educational methods, such as conferences and tutorials or informal education at the bedside, have many drawbacks for delivery of this information in a universal, standardized, and timely manner. The rapid uptake of portable media devices makes portable video media (PVM) a potential alternative to current educational methods. To compare PVM to standard verbal communication (SVC) for surgical information delivery and educational training for nurses and evaluate its impact on knowledge acquisition and participant satisfaction. Prospective, multicenter, randomized controlled crossover trial. Two hospitals: Gosford District Hospital and Wyong Hospital. Seventy-two nursing staff (36 at each site). Information delivery via PVM--7-minute video compared to information delivered via SVC. Knowledge acquisition was measured by a 32-point questionnaire, and satisfaction with the method of education delivery was measured using the validated Client Satisfaction Questionnaire (CSQ-8). Knowledge acquisition was higher via PVM compared to SVC 25.9 (95% confidence interval [CI] 25.2-26.6) versus 24.3 (95% CI 23.5-25.1), p = .004. Participant satisfaction was higher with PVM 29.5 (95% CI 28.3-30.7) versus 26.5 (95% CI 25.1-27.9), p = .003. Following information delivery via SVC, participants had a 6% increase in knowledge scores, 24.3 (95% CI 23.5-25.1) versus 25.7 (95% CI 24.9-26.5) p = .001, and a 13% increase in satisfaction scores, 26.5 (95% CI 25.1-27.9) versus 29.9 (95% CI 28.8-31.0) p information delivery via PVM. PVM provides a novel method for providing education to nurses that improves knowledge retention and satisfaction with the educational process. © 2016 Sigma Theta

    During a two-year period, eighty-nine patients who were scheduled to have a total knee arthroplasty for the treatment of degenerative osteoarthrosis were randomly assigned to one of two groups: resurfacing of the patella or retention of the patella. All patients received the same posterior cruciate-sparing prosthesis, and all operations were performed by, or under the direct supervision of, one of us. Three patients died in the early postoperative period. The remaining eighty-six patients (118 knees; fifty-eight that had had resurfacing of the patella and sixty that had not) formed the study group. They were followed for a mean of thirty months (range, twenty-four to forty-four months). Evaluation was performed with use of the clinical scoring system of The Knee Society, a patient-satisfaction questionnaire, specific questions regarding patellofemoral symptoms and function, and radiographs. All clinical evaluations were performed by the same research nurse, without the involvement of a physician, in a blinded manner (neither the nurse nor the patient had knowledge of whether the patella had been resurfaced). Preoperatively, the mean Knee Society score, on a scale ranging from 0 to 200 points, was 89.7 points (range, 33 to 132 points); postoperatively, this score improved to a mean of 172.7 points (range, 98 to 200 points). With the numbers available for study, we could detect no significant difference between the knees that had had patellar resurfacing and those that had not with regard to the over-all score (p = 0.63), the subscore for pain (p = 0.56), or the subscore for function (p = 0.77). We also could detect no difference between the treatment groups, with the numbers available, with regard to patient satisfaction or the responses to questions involving the function of the patellofemoral joint, including the ability to exit from an automobile, to rise from a chair, and to climb stairs. Thirty-two patients had bilateral total knee replacement with resurfacing

    Free-flap failure is usually caused by venous or arterial thrombosis. In many cases, lack of experience and surgical delay also contribute to flap loss. The authors prospectively analyzed the outcome of 57 free flaps over a 28-month period (January, 1999 to April, 2001). The setting was a university hospital tertiary referral center. Anastomotic technique, ischemia time, choice of anticoagulant, and the grade of surgeon were recorded. The type of flap, medications, and co-morbidities, including preoperative radiotherapy, were also documented. Ten flaps were re-explored (17 percent). There were four cases of complete flap failure (6.7 percent) and five cases of partial failure (8.5 percent). In patients who received perioperative systemic heparin or dextran, there was no evidence of flap failure (p = .08). The mean ischemia time was similar in flaps that failed (95 +\\/- 29 min) and in those that survived (92 +\\/- 34 min). Also, the number of anastomoses performed by trainees in flaps that failed (22 percent), was similar to the number in flaps that survived (28 percent). Nine patients received preoperative radiotherapy, and there was complete flap survival in each case. This study reveals that closely supervised anastomoses performed by trainees may have a similar outcome to those performed by more senior surgeons. There was no adverse effect from radiotherapy or increased ischemia time on flap survival.

    Objective: To evaluate the clinical efficacy of Qianlie'an(前列安,QLA) suppository via anal route administration in treating chronic prostatitis syndrome. Methods: A randomized open-labelled prospective controlled trial was carried out. The total of 120 patients with chronic prostatitis syndrome were randomly divided into 2 groups: 60 patients in the treated group who were treated with QLA suppository combined with ofloxacin, and the other 60 patients in the control group who were given ofloxacin alone. The efficacy was evaluated by WBC count in the expressed prostatic secretion (EPS) and the Chronic Prostatitis Symptom Index (CPSI) made by the National Institute of Health (NIH). The clinical effects were also observed in a 4-week follow-up. Results: All but six cases completed the trial and the follow-up.It showed that in the treated group recovery rate was 17. 2%, markedly effective rate 34. 5%, effective rate 32.8%, total markedly effective rate 51.7%, and total effective rate 84. 5%, all of which were superior to those in the control group (total markedly effective rate 32.1% and total effective rate 66.1%, respectively), P<0.01. Conclusion: Administration of QLA suppository via anal route combined with oral antibiotics is an effective therapy for chronic prostatitis syndrome. It can relieve the symptoms of chronic prostatitis syndrome markedly and rapidly. It is a new choice for treatment of the disease.

    Full Text Available OBJECTIVE: To investigate the variations in blood glucose levels, hemodynamic effects and patient anxiety scores during tooth extraction in patients with type 2 diabetes mellitus T2DM and coronary disease under local anesthesia with 2% lidocaine with or without epinephrine. STUDY DESIGN: This is a prospective randomized study of 70 patients with T2DM with coronary disease who underwent oral surgery. The study was double blind with respect to the glycemia measurements. Blood glucose levels were continuously monitored for 24 hours using the MiniMed Continuous Glucose Monitoring System. Patients were randomized into two groups: 35 patients received 5.4 mL of 2% lidocaine, and 35 patients received 5.4 mL of 2% lidocaine with 1:100,000 epinephrine. Hemodynamic parameters (blood pressure and heart rate and anxiety levels were also evaluated. RESULTS: There was no difference in blood glucose levels between the groups at each time point evaluated. Surprisingly, both groups demonstrated a significant decrease in blood glucose levels over time. The groups showed no significant differences in hemodynamic and anxiety status parameters. CONCLUSION: The administration of 5.4 mL of 2% lidocaine with epinephrine neither caused hyperglycemia nor had any significant impact on hemodynamic or anxiety parameters. However, lower blood glucose levels were observed. This is the first report using continuous blood glucose monitoring to show the benefits and lack of side effects of local anesthesia with epinephrine in patients with type 2 diabetes mellitus and coronary disease.

    This prospective randomized controlled study evaluated the clinical and radiographic outcome of endodontic microsurgery when using iRoot BP Plus Root Repair Material (BP-RRM; Innovative BioCeramix Inc, Vancouver, BC, Canada) or mineral trioxide aggregate (MTA) as the retrograde filling material and analyzed the relationship between some potential prognostic factors and the outcome of the surgery. By using strict inclusion and exclusion criteria, 240 teeth were successfully enrolled and randomly and equally allocated to either the MTA or BP-RRM treatment group. A standardized surgical procedure was performed by a single operator. The patients were followed up at 1 week, 3 months, 6 months, and 12 months; follow-up included clinical and radiographic examination. Clinical and radiographic evaluations acquired at the 12-month follow-up were taken as the primary outcome. For the identification of prognostic factors, the dichotomous outcome (success vs failure) was taken as the dependent variable. A total of 158 teeth were analyzed at the 12-month follow-up, including 87 teeth in the MTA group and 71 teeth in the BP-RRM group. The success rate in the MTA and BP-RRM groups was 93.1% (81/87 teeth) and 94.4% (67/71 teeth), respectively (P > .05).

    Full Text Available Background: Wear debris of polyethylene has become a restraining factor of the durability for total hip arthroplasty (THA. Ceramic on ceramic (COC has better wear resistance while the squeaking sound and prosthesis fracture are of concern. It is still a controversy that bearing couples are better for THA. Methods: We performed a systematic review of all English articles identified from PubMed (1966-, Embase (1980- and the Cochrane Library. Clinical outcomes, complications, revision rates, and radiographic outcomes of COC-THA and ceramic on polyethylene (COP-THA were compared and evaluated. Results: Eight prospective randomized trials enrolling a total of 1508 patients and 1702 THA surgeries were identified. Our results demonstrated the prosthesis fracture and the squeaking sound is significantly higher in COC group and higher wear rate of the COP. Hip function, loosening rate, dislocation rate, revision rate, and the osteolysis rate were comparable between two groups. According to Grading of Recommendations Assessment, Development and Evaluation system assessment, the strength of evidence was high for prosthesis fracture, dislocation, osteolysis, and moderate for radiolucent line or loosening, hip noise, and revision. Conclusions: Up to now, there is insufficient evidence to identify any clinical advantage of COC compared with COP. Longer follow-up of larger randomized trial is needed to clarify the outcomes.

    Full Text Available The objective of this study was to examine the effects of estrogen-based hormone therapy (HT on regional cerebral metabolism in postmenopausal women (mean age = 58, SD = 5 at risk for development of dementia. The prospective clinical trial design included pre- and post-intervention neuroimaging of women randomized to continue (HT+ or discontinue (HT- therapy following an average of 10 years of use. The primary outcome measure was change in brain metabolism during the subsequent two years, as assessed with fluorodeoxyglucose-18 positron emission tomography (FDG-PET. Longitudinal FDG-PET data were available for 45 study completers. Results showed that women randomized to continue HT experienced relative preservation of frontal and parietal cortical metabolism, compared with women randomized to discontinue HT. Women who discontinued 17-β estradiol (17βE-based HT, as well as women who continued conjugated equine estrogen (CEE-based HT, exhibited significant decline in metabolism of the precuneus/posterior cingulate cortical (PCC area. Significant decline in PCC metabolism was additionally seen in women taking concurrent progestins (with either 17βE or CEE. Together, these findings suggest that among postmenopausal subjects at risk for developing dementia, regional cerebral cortical metabolism is relatively preserved for at least two years in women randomized to continue HT, compared with women randomized to discontinue HT. In addition, continuing unopposed 17βE therapy is associated specifically with preservation of metabolism in PCC, known to undergo the most significant decline in the earliest stages of Alzheimer's disease.ClinicalTrials.gov NCT00097058.

    Hysterectomy is often part of pelvic organ prolapse repair. However, this may offer no benefit when compared to uterine preservation. We aimed to prospectively evaluate a minimally invasive bilateral sacrospinous hysteropexy using polypropylene mesh. We hypothesized that anatomic success and patient satisfaction can be achieved with this technique. Women with uterovaginal prolapse desiring surgery who had completed childbearing were enrolled. Preoperative assessment included standardized prolapse examination and validated symptom and pain scale questionnaires. Women with prior pelvic organ prolapse repair or any contraindication to uterine preservation were excluded. Data including demographic, operative and postoperative information was collected on patients for 1 year following surgery. Continuous variables are summarized as means (standard deviation) and categorical variables are summarized as frequencies and percentages. A mixed-effects model was used to evaluate the changes in questionnaire scores and outcomes at 6 months and 12 months after surgery with random effects accounting for the center effect with adjustment for age. The study group comprised 99 women from three female pelvic medicine and reconstructive surgery (urogynecology) centers. The average age of the participants was 67.0 years (11.32 years), BMI 26.04 kg/m(2) (3.56 kg/m(2)), and the majority were multiparous (98.9%) and menopausal (90.9%). Overall success at 12 months, as measured by composite outcome was 97.7% (with the Ba point as the anatomic landmark) and 96.6% (with the C point as the anatomic landmark). The overall exposure rate was 6.52% and reoperation rate was 7.53%. All subjective questionnaire scores and anatomic outcomes had improved at 12 months. Sacrospinous hysteropexy using a minimally invasive polypropylene mesh kit is an effective and safe technique for addressing uterovaginal prolapse as an alternative to hysterectomy at the time of pelvic reconstructive surgery.

This complication has a negative impact on the success of the technique. In spite of this, there are no clear guidelines concerning how to take care of the exit site. The objective of this study was to assess the efficacy of polyhexanide in preventing exit-site infection over a 12-month period. We designed a single-center, prospective, open-labeled, randomized controlled clinical trial with parallel groups. Requirements for participation in the study included implantation of the peritoneal catheter at least six weeks before entering the study and no infectious complications requiring either hospital admission or antibiotic treatment for at least three months before entering into the study. Patients were randomized to be daily cured as follows: Group A: traditional care with saline serum and povidone-iodine; and Group B: polyhexanide solution. Exit sites were evaluated at baseline and every four to six weeks or if any event occurred, according to the Twardowski criteria. Of the 60 included patients, 46 completed the 12-month follow-up period. Six underwent transplantation, five died and three were transferred to hemodialysis (HD). The treatment was well tolerated, with no side effects nor abandonments due to such effects. Throughout the study period, six patients (20%) undergoing traditional care and only two (6,7%) receiving polyhexanide developed an exit-site infection (p = 0.032). There were a total number of 12 infections; nine occurred in patients following the traditional approach and only three in patients treated with polyhexanide (p = 0.037). The germs responsible for the infections were: S. aureus (six cases), Corynebacterium jeikeium (two cases) and P. aeruginosa (one case) in the saline serum and povidone-iodine group and P. aeruginosa (three cases) in the

Due to the fact that IL-1beta (produced by macrophages is preoperatively indifferent in various gastrointestinal cancer types our major outcome criterion was the perioperative (overall level of IL-1beta in peritoneal fluid. Results Cytokine values were significantly lower after TRD lavage for IL-1beta, IL-6, and IL-10. Perioperative complications did not differ. The median follow-up was 50.0 months. The overall mortality rate (28 vs. 25, p = 0.36, the cancer-related death rate (17 vs. 19, p = .2, the local recurrence rate (7 vs. 12, p = .16, the distant metastasis rate (13 vs. 18, p = 0.2 as well as the time to relapse were not statistically significant different. Conclusion Reduced cytokine levels might explain a short term antitumorigenic intraperitoneal effect of TRD. But, this study analyzed different types of cancer.

    Full Text Available Abstract Background Several minimally invasive saphenous vein harvesting techniques have been developed to reduce morbidities associated with coronary artery bypass grafting. This prospective, randomized study was designed to compare two commonly used minimally invasive saphenous vein harvesting techniques, the SaphLITE Retractor System (Teleflex Medical and the Clearglide Endoscopic Vessel Harvesting System (Ethicon CardioVations, Inc.. Methods Between January 2003 and March 2004, a total of 200 patients scheduled for primary, nonemergent coronary artery bypass grafting, with or without concomitant procedures were randomized into two groups: SaphLITE (n = 100 and Clearglide (n = 100. Pre-, intra- and postoperative data was collected and subjected to statistical analysis. Randomization provided homogenous groups with respect to preoperative risk factors. Results Harvest location for the SaphLITE group was thigh (n = 40, lower leg (n = 5 and both lower leg and thigh (n = 55. The location of harvest for the Clearglide group was thigh (n = 3, lower leg (n = 16 and both lower leg and thigh (n = 81. The mean incision length was 3.6 cm (range, 2–6 in the SaphLITE group versus 2.1 cm (range, 1–4 in the Clearglide group (p Conclusion The saphenous vein can be safely harvested utilizing the SaphLITE and Clearglide systems. While the Clearglide system allows for fewer incisions (number and length and less harvest time, these benefits may be outweighed by the increased cost of the Clearglide system compared to the SaphLITE retractor.

    Adherence to prescribed antihypertensive agents is critical because control of elevated blood pressure is the single most important way to prevent stroke and other end organ damage. Unfortunately, nonadherence remains a significant problem. Previous interventions designed to improve adherence have demonstrated only small benefits of strategies that target single facets such as understanding medication directions. The intervention described here is informed by prospective memory theory and performance of older adults in laboratory-based paradigms and uses a comprehensive, multifaceted approach to improve adherence. It incorporates multiple strategies designed to support key components of prospective remembering involved in taking medication. The intervention is delivered by nurses in the home with an education control group for comparison. Differences between groups in overall adherence following the intervention and 6 months later will be tested. Systolic and diastolic blood pressure levels also will be examined between groups and as it relates to adherence. Intra-individual regression is planned to examine change in adherence over time and its predictors. Finally, we will examine the association between executive function/working memory and adherence, predicting that adherence will be related to executive/working memory in the control group but not in the intervention group.

    Full Text Available OBJECTIVE: This prospective randomized clinical study was conducted to evaluate the safety and tolerability of early oral feeding after colorectal operations. METHODS: A total of 199 patients underwent colorectal surgery and were randomly assigned to early feeding (n = 99 or a regular diet (n = 100. Patients’ characteristics, diagnoses, surgical procedures, comorbidity, bowel movements, defecation, nasogastric tube reinsertion, time of tolerance of solid diet, complications, and length of hospitalization were assessed. RESULTS: The two groups were similar in terms of gender, age, diagnosis, surgical procedures, and comorbidity. In the early feeding group, 85.9% of patients tolerated the early feeding schedule. Bowel movements (1.7±0.89 vs. 3.27±1.3, defecation (3.4±0.77 vs. 4.38±1.18 and time of tolerance of solid diet (2.48±0.85 vs. 4.77±1.81 were significantly earlier in the early feeding group. There was no change between the groups in terms of nasogastric tube reinsertion, overall complication or anastomotic leakage. Hospitalization (5.55±2.35 vs. 9.0±6.5 was shorter in the early feeding group. CONCLUSIONS: The present study indicated that early oral feeding after elective colorectal surgery was not only well tolerated by patients but also affected the postoperative outcomes positively. Early postoperative feeding is safe and leads to the early recovery of gastrointestinal functions.

    AIM: To determine whether absorbable sutures or non-absorbable sutures are better in preventing surgical site infection (SSI), in this paper we discuss the results of a randomized clinical trial which examined the type of sutures used during hepatectomy. METHODS: All hepatic resections performed from January 2007 to November 2008 at the Department of Surgery at Iizuka Hospital in Japan were included in this study. There were 125 patients randomly assigned to an absorbable sutures (Vicryl) group or non-absorbable sutures (Silk) group. RESULTS: SSI was observed in 13.6% (17/125) patients participating in this study, 11.3% in the Vicryl group and 15.8% in the Silk group. Incisional SSI including superficial and deep SSI, was observed in 8% of the Vicryl group and 9.5% of the Silk group. Organ/ space SSI was observed in 3.2% of the Vicryl group and 6.0% of the Silk group. There were no significant differences, but among the patients with SSI, the period for recovery was significantly shorter for the Vicryl group compared to the Silk group. CONCLUSION: The incidence of SSI in patients receiving absorbable sutures and silk sutures is not significantly different in this randomized controlled study; however, the period for recovery in patients with SSI was significantly shorter for absorbable sutures.

    Full Text Available OBJECTIVE: To compare the functional results of carpectomy and four-corner fusion surgical procedures for treating osteoarthrosis following carpal trauma. METHODS: In this prospective randomized study, 20 patients underwent proximal row carpectomy or four-corner fusion to treat wrist arthritis and their functional results were compared. The midcarpal joint was free of lesions in all patients. RESULTS: Both proximal row carpectomy and four-corner fusion reduced the pain. All patients had a decreased range of motion after surgery. The differences between groups were not statistically significant. CONCLUSIONS: Functional results of the two procedures were similar as both reduced pain in patients with scapholunate advanced collapse/scaphoid non-union advanced collapse (SLAC/SNAC wrist without degenerative changes in the midcarpal joint.

    There is controversy over the need for electrocauterization of the patella in non-resurfacing total knee arthroplasty (TKA). We investigated whether this procedure is beneficial through a prospective randomized controlled trial. Fifty patients who underwent electrocautery were compared with 50 patients who did not undergo this procedure. We determined cartilage status, preoperative and postoperative American Knee Society (AKS) score, the Western Ontario and McMaster Universities score (WOMAC) and the Patellofemoral (PF) scores for a minimum of 5 years. The two groups did not differ significantly in demographics, intraoperative cartilage status, or preoperative or postoperative outcomes. No complications were detected in either group. We found no benefits of electrocautery of the patella in patellar non-resurfacing TKA up to 5 years. Copyright © 2015 Elsevier Inc. All rights reserved.

    A prospective randomized study was performed comparing the efficacy of controlled cold therapy (CCT) with the efficacy of ice therapy in the postoperative treatment of 72 patients with carpal tunnel syndrome. Immediately after surgery, patients applied either a temperature-controlled cooling blanket (CCT) or a standard ice pack over their surgical dressings. Pain was assessed by visual analog scale and swelling by wrist circumference preoperatively, immediately after surgery, and on postoperative day 3. Patients kept log books of daily treatment times. Narcotic use (of Vicodin ES) was determined by pill count at day 3 and by daily log book recordings. Patients who used CCT showed significantly greater reduction in pain, edema (wrist circumference), and narcotic use at postoperative day 3 than did those using ice therapy. This study indicates that after carpal tunnel surgery, the use of CCT, compared with traditional ice therapy, provides patients with greater comfort and lessens the need for narcotics.

    Full Text Available Abstract Background Prospective investigations of complete decongestive lymphatic physiotherapy (CDPT, including manual lymphatic drainage (MLD, have validated the efficacy of these interventions for the initial reduction of edema and long-term maintenance of limb volume in lymphedema. However, CDPT demands substantial time and effort from patients to maintain these benefits; the treatments are not always well-accepted, and patients may suffer from a deterioration in quality-of-life or a time-dependent loss of initial treatment benefits. A new device designed for home use by the patient, the Flexitouch™, has been developed to mechanically simulate MLD. We have undertaken a prospective, randomized, crossover study of the efficacy of the Flexitouch™, when compared to massage, in the self-administered maintenance therapy of lymphedema. Methods A prospective, randomized, crossover study of maintenance therapy was performed in 10 patients with unilateral breast cancer-associated lymphedema of the arm. Each observation phase included self-administered treatment with the Flexitouch™ or massage, 1 hour daily for 14 days, respectively, followed by crossover to the alternate treatment phase. Each treatment phase was preceded by a 1 week treatment washout, with use of garment only. The sequence of treatment was randomly assigned. The potential impact of treatment modality on quality of life was assessed with serial administration of the SF-36. Results Statistical analysis disclosed that the order of treatment had no outcome influence, permitting 10 comparisons within each treatment group. Post-treatment arm volume reduced significantly after the Flexitouch™, but not after self-administered massage. The patients' mean weight decreased significantly with Flexitouch™ use, but not with massage. The Flexitouch™ device was apparently well-tolerated and accepted by patients. Serial SF-36 administration showed no deterioration in physical or

    Background: Replacement of caloric sweeteners with lower- or no-calorie alternatives may facilitate weight loss or weight maintenance by helping to reduce energy intake; however, past research examining low-calorie sweeteners (LCSs) and body weight has produced mixed results. Objective: The objective was to systematically review and quantitatively evaluate randomized controlled trials (RCTs) and prospective cohort studies, separately, that examined the relation between LCSs and body weight and composition. Design: A systematic literature search identified 15 RCTs and 9 prospective cohort studies that examined LCSs from foods or beverages or LCSs consumed as tabletop sweeteners. Meta-analyses generated weighted mean differences in body weight and composition values between the LCS and control groups among RCTs and weighted mean correlations for LCS intake and these parameters among prospective cohort studies. Results: In RCTs, LCSs modestly but significantly reduced all outcomes examined, including body weight (−0.80 kg; 95% CI: −1.17, −0.43), body mass index [BMI (in kg/m2): −0.24; 95% CI: −0.41, −0.07], fat mass (−1.10 kg; 95% CI: −1.77, −0.44), and waist circumference (−0.83 cm; 95% CI: −1.29, −0.37). Among prospective cohort studies, LCS intake was not associated with body weight or fat mass, but was significantly associated with slightly higher BMI (0.03; 95% CI: 0.01, 0.06). Conclusions: The current meta-analysis provides a rigorous evaluation of the scientific evidence on LCSs and body weight and composition. Findings from observational studies showed no association between LCS intake and body weight or fat mass and a small positive association with BMI; however, data from RCTs, which provide the highest quality of evidence for examining the potentially causal effects of LCS intake, indicate that substituting LCS options for their regular-calorie versions results in a modest weight loss and may be a useful dietary tool to improve

    Full Text Available The purpose of this study is to evaluate educational computer aided teaching materials (CATM which designed by skilled prospective class teachers towards 4 and 5th grade science level according to the principles of an educational software and teaching methods and techniques. Therefore, materials were firstly scored with an educational software assessment scale and findings were presented in the tables after calculated by Microsoft Excel. Secondly, prospective teachers’ using level of teaching methods and techniques, and measurement and assessment methods and techniques were revealed from their CATM's interface. The sample of the study was consisted 29 prospective class teachers. As a result of the study, although prospective teachers designed successive materials, it is understood that they have paid more attention to visual design properties and functionality such as linking between pages, colored backgrounds, interactive buttons, interactive guidance and assistance properties, and multi-media properties excluding principles of editing content criteria. They tried to present science subject by concept mapping, brainstorming, case study and demonstration as teaching methods/techniques with assessment techniques such as multiple-choice test, matching, concept map as assessment respectively. In general, the findings of the study showed that designing and developing CATM allowed prospective teachers to increase their educational technology competencies, self-esteem and confidence. In conclusion, it is revealed that prospective teachers are in need of experiences and environment about how to integrate pedagogy and technology knowledge.

    In patients with paroxysmal atrial fibrillation (pAF), pulmonary vein isolation (PVI) has become an accepted treatment option with single procedure success rates of 60-80%. A repeat ablation is performed in ∼30% of patients because of arrhythmia recurrence. The strategy for this repeat procedure is not defined. Patients with pAF recurrence after PVI were prospectively randomized and underwent a second ablation procedure with either PVI of all reconnected veins or PVI with an additional left atrial anterior line. Follow-up in our arrhythmia clinic was every 3 months up to 12 months including 7 day Holter monitoring. A total of 77 patients (mean age 63 ± 9 years, 69% males) were included in the analysis. A repeat PVI was performed in 41 patients, PVI + anterior line in 36 patients. After a follow-up of 12 months, 26 of 41 (63%) patients after repeat PVI and 18 of 36 (50%) patients with PVI + anterior line were in stable sinus rhythm off antiarrhythmic medication (P = 0.26). In most patients (12 of 15 patients with PVI and 14 of 18 patients with PVI + anterior line) with an arrhythmia recurrence after the second procedure, the recurring arrhythmia was paroxysmal AF. In 2 of 15 patients of the PVI group and in 4 of 18 patients of the PVI + anterior line group atypical flutter was the reoccurring arrhythmia (P = NS). In this prospective randomized trial, patients with a recurrence of paroxysmal AF had no better outcome after repeat PVI + one left atrial line compared with patients with repeat PVI only.

    Extracorporeal shock wave therapy improves erectile function in patients with Peyronie's disease. However, erectile dysfunction still persists in many cases. We aimed to investigate the effects of extracorporeal shock wave therapy plus tadalafil 5 mg once daily in the management of patients with Peyronie's disease and erectile dysfunction not previously treated. One hundred patients were enrolled in a prospective, randomized, controlled study. Patients were randomly allocated to receive either extracorporeal shock wave therapy alone for 4 weeks (n = 50) or extracorporeal shock wave therapy plus tadalafil 5 mg once daily for 4 weeks (n = 50). Main outcome measures were: erectile function (evaluated through the shortened version of the International Index of Erectile Function), pain during erection (evaluated through a Visual Analog Scale), plaque size, penile curvature and quality of life (evaluated through an internal questionnaire). Follow-up evaluations were performed after 12 and 24 weeks. In both groups, at 12 weeks follow-up, mean Visual Analog Scale score, mean International Index of Erectile Function score and mean quality of life score ameliorated significantly while mean plaque size and mean curvature degree were unchanged. Intergroup analysis revealed a significantly higher mean International Index of Erectile Function score and quality of life score in patients receiving the combination. After 24 weeks, intergroup analysis revealed a significantly higher mean International Index of Erectile Function score and mean quality of life score in patients that received extracorporeal shock wave therapy plus tadalafil. In conclusion extracorporeal shock wave therapy plus tadalafil 5 mg once daily may represent a valid conservative strategy for the management of patients with Peyronie's disease and erectile dysfunction.

    Full Text Available Abstract Background Whether epidural analgesia for labor prolongs the active-first and second labor stages and increases the risk of vacuum-assisted delivery is a controversial topic. Our study was conducted to answer the question: does lumbar epidural analgesia with lidocaine affect the progress of labor in our obstetric population? Method 395 healthy, nulliparous women, at term, presented in spontaneous labor with a singleton vertex presentation. These patients were randomized to receive analgesia either, epidural with bolus doses of 1% lidocaine or intravenous, with meperidine 25 to 50 mg when their cervix was dilated to 4 centimeters. The duration of the active-first and second stages of labor and the neonatal apgar scores were recorded, in each patient. The total number of vacuum-assisted and cesarean deliveries were also measured. Results 197 women were randomized to the epidural group. 198 women were randomized to the single-dose intravenous meperidine group. There was no statistical difference in rates of vacuum-assisted delivery rate. Cesarean deliveries, as a consequence of fetal bradycardia or dystocia, did not differ significantly between the groups. Differences in the duration of the active-first and the second stages of labor were not statistically significant. The number of newborns with 1-min and 5-min Apgar scores less than 7, did not differ significantly between both analgesia groups. Conclusion Epidural analgesia with 1% lidocaine does not prolong the active-first and second stages of labor and does not increase vacuum-assisted or cesarean delivery rate.

    Adhesive small bowel obstruction (ASBO) is an important cause of hospital admission, is associated with significant morbidity and mortality, and therefore is a substantial burden for healthcare systems worldwide. Icodextrin 4% solution (Adept, Shire Pharmaceuticals, UK) is a high-molecular-weight a-1,4 glucose polymer approved in Europe for use as intraoperative lavage and postoperative instillation to reduce the occurrence of post-surgery intra-abdominal adhesions. The present clinical study aimed to evaluate the safety and effectiveness of icodextrin 4% in decreasing the incidence, extent, and severity of adhesions in patients after abdominal surgery for ASBO. The study was a single-center prospective, randomized investigation. The study is designed and conducted in compliance with the principles of Good Clinical Practice regulations. Safety and efficacy of icodextrin 4% in the study group are compared to no anti-adhesion treatment in a parallel control group with blinded evaluation of primary endpoints. Primary endpoints are the evaluation of the therapeutic role of icodextrin 4% in reducing ASBO recurrence incidence and the need of laparotomies for ASBO recurrence, as well as adhesion formation (with evaluation of their incidence, extent, and severity). A sum of 181 patients with ASBO and surgical indication to laparotomy were enrolled and randomized in two groups. Patients were submitted to adhesiolysis with bowel resection if required with or without anastomosis. The first group received traditional treatment (control group), whereas the second group was treated with the addition of icodextrin 4% solution before the abdominal closure. Ninety-one patients were randomized to have icodextrin 4% solution administered intraperitoneally, and 90 patients were randomized to have the traditional treatment. The two study groups were homogeneous regarding their baseline characteristics. The ASBO recurrence rate was 2.19% (2/91) in the icodextrin groups vs 11.11% (10

The aim of this study was to compare the early clinical results of TKA performed with patient-specific CT-based instrumentation and conventional technique. A prospective, randomized controlled trial on 112 patients was performed between January 2011 and December 2011. A group of 112 patients who met the inclusion and exclusion criteria were enrolled in this study and randomly assigned to an experimental or control group. The experimental group comprised 52 patients who received the Signature CT-based implant positioning system, and the control group consisted of 60 patients with conventional instrumentation. Clinical outcomes were evaluated with the KSS scale, WOMAC scale, and VAS scales to assess knee pain severity and patient satisfaction with the surgery. Specified in-hospital data were recorded. Patients were followed up for 12 months. At one year after surgery, there were no statistically significant differences between groups with respect to clinical outcomes and in-hospital data, including operative time, blood loss, hospital length of stay, intraoperative observations, and postoperative complications. Further high-quality investigations of various patient-specific systems and longer follow-up may be helpful in assessing their utility for TKA.

    Full Text Available Background/Aims. One of the causes of uncontrolled secondary hyperparathyroidism (sHPT is patient’s poor drug adherence. We evaluated the clinical benefits of an integrated care approach on the control of sHPT by cinacalcet. Methods. Prospective, randomized, controlled, multicenter, open-label study. Fifty hemodialysis patients on a stable dose of cinacalcet were randomized to an integrated care approach (IC or usual care approach (UC. In the IC group, cinacalcet adherence was monitored using an electronic system. Results were discussed with the patients in motivational interviews, and drug prescription adapted accordingly. In the UC group, drug adherence was monitored, but results were not available. Results. At six months, 84% of patients in the IC group achieved recommended iPTH targets versus 55% in the UC group (. The mean cinacalcet taking adherence improved by 10.8% in the IC group and declined by 5.3% in the UC group (. Concomitantly, the mean dose of cinacalcet was reduced by 7.2 mg/day in the IC group and increased by 6.4 mg/day in the UC group (. Conclusions. The use of a drug adherence monitoring program in the management of sHPT in hemodialysis patients receiving cinacalcet improves drug adherence and iPTH control and allows a reduction in the dose of cinacalcet.

    There is no sufficient data to conclude the benefit of assisted hatching (AH) for advanced age patients. However, AH is routinely performed for advanced age patients undergoing in vitro fertilization (IVF) in China based on some retrospective evidence. It is important to assess the benefit of AH procedure for advanced age patients, especially by analyzing the data from China. This is a prospective randomized controlled trial to evaluate the effect of laser AH in the advanced age patients undergoing IVF. A total of 256 patients conformed to the inclusion criteria, and 78 were excluded by exclusion criteria. A total of 178 patients were eligible and randomized to 2 groups (82 AH group and 96 control group). Laser AH (zona thinning) was performed in the AH group. There were no statistical significance in basic clinical parameters between the 2 groups. No difference was found in implantation rate (AH vs control, 32.45% vs 39.29%) and clinical pregnancy rate (AH vs control, 48.78% vs 59.38%). Our data did not find any benefit of laser AH in improving implantation or pregnancy rates in advanced age women. Due to the potential risk and increasing financial burden, AH should not be routinely performed in first fresh IVF embryo transfer cycle for advanced age women.

    The purpose of this prospective, randomized, double-blind crossover study was to evaluate the anesthetic efficacy of 2% lidocaine with 1:100,000 and 1:50,000 epinephrine and 3% mepivacaine in maxillary lateral incisors and first molars. Sixty subjects randomly received, in a double-blind manner, maxillary lateral incisor and first molar infiltrations of 1.8 mL of 2% lidocaine with 1:100,000 epinephrine, 2% lidocaine with 1:50,000 epinephrine, and 3% mepivacaine at three separate appointments spaced at least 1 week apart. The teeth were pulp tested in 3-minute cycles for a total of 60 minutes. Anesthetic success and the onset of pulpal anesthesia were not significantly different between 2% lidocaine with either 1:100,000 or 1:50,000 epinephrine and 3% mepivacaine for the lateral incisor and first molar. Increasing the epinephrine concentration from 1:100,000 to 1:50,000 in a 2% lidocaine formulation significantly decreased pulpal anesthesia of short duration for the lateral incisor but not the first molar. For both the lateral incisor and first molar, 3% mepivacaine significantly increased pulpal anesthesia of short duration compared with 2% lidocaine with either 1:100,000 or 1:50,000 epinephrine.

    To examine the effect of patient-selected music intervention during daily weaning trials for patients on prolonged mechanical ventilation. Using a crossover repeated measures design, patients were randomized to music vs no music on the first intervention day. Provision of music was alternated for 6 days, resulting in 3 music and 3 no music days. During weaning trials on music days, data were obtained for 30min prior to music listening and continued for 60min while patients listened to selected music (total 90min). On no music days, data were collected for 90min. Outcome measures were heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2), blood pressure (BP), dyspnea and anxiety assessed with a visual analog scale (VAS-D, VAS-A) and weaning duration (meanh per day on music and non-music days). Of 31 patients randomized, 23 completed the 6-day intervention. When comparisons were made between the 3 music and 3 no music days, there were significant decreases in RR and VAS-D and a significant increase in daily weaning duration on music days (pmusic days (pmusic during daily weaning trials is a simple, low-cost, potentially beneficial intervention for patients on prolonged mechanical ventilation.

    The patient's position during an axillary thoracotomy can cause postoperative pain and decrease mobility of the ipsilateral shoulder. In this study, we assessed whether the implementation of a standardized analgesia program using transcutaneous electrical nerve stimulation (TENS) decreases local pain and improves ipsilateral shoulder mobility. Randomized, single-blind, single-center clinical trial of 50 patients who had undergone anatomical lung resection via axillary muscle-sparing thoracotomy. Patients were treated with TENS devices for 30 minutes every 8 hours, beginning on postoperative day 1. Pain and mobility of the affected limb were recorded at the same time on postoperative days 1 through 3. A visual analogue scale was used for pain assessment and shoulder mobility was assessed with a goniometer. Results were compared using a non-parametric test. Twenty-five patients were randomized to each group. Mean age of the control group was 62.7±9.3 years and 63.4±10.2 years in the experimental group. Shoulder mobility parameters were similar in both groups on all postoperative days. However, pain during flexion significantly decreased on day 2 (P=.03) and day 3 (P=.04) in the experimental group. The use of TENS decreases pain from shoulder flexion in patients undergoing axillary thoracotomy for pulmonary resection. Copyright © 2014 SEPAR. Published by Elsevier Espana. All rights reserved.

    Perioperative fluid restriction might be beneficial in specific clinical settings. In this prospective, randomized and blinded study, we assessed whether peristaltic pneumatic compression of the legs can support restrictive fluid management strategies by reducing intraoperative fluid demand and improving hemodynamic stability. Seventy patients scheduled for minor surgery were randomly assigned to receive either intraoperative peristaltic pneumatic compression or placebo compression. Both groups received fluid therapy according to a goal-directed protocol with a crystalloid base rate of 2 ml · kg⁻¹ · h⁻¹ and bolus infusions of 250 ml crystalloids triggered by hypotension, tachycardia, or high Pleth Variability Index. Patients treated with peristaltic pneumatic compression received less intravenous fluid: median (interquartile range) 286 (499) versus 921 (900) ml (P pneumatic peristaltic compression group (P pneumatic peristaltic compression, the median cumulative time of hypotension was shorter (0 [12.5] vs. 22.6 [22.8] min; P = 0.002), fewer hypotensive events were recorded (39 vs. 137; P = 0.001), and median lowest individual systolic pressure was higher (92 [8] vs. 85 [16] mmHg; P = 0.002). This study demonstrates that peristaltic pneumatic compression of the legs significantly improves hemodynamic stability and reduces fluid demand during minor surgery.

    AIM: To determine the efficacy of perioperative parecoxib injection on postoperative pain relief after laparoscopic cholecystectomy.METHODS: A prospective, double-blind, randomized,placebo-controlled study was conducted on 70 patients who underwent elective laparoscopic cholecystectomy under general anesthesia at Siriraj Hospital, Bangkok,from January 2006 to December 2007. Patients were randomized to receive either 20 mg parecoxib infusion 30 min before induction of anesthesia and at 12 h after the first dose (treatment group), or normal saline infusion, in the same schedule, as a placebo (control group). The degree of the postoperative pain was assessed every 3 h in the first 24 h after surgery, and then every 12 h the following day, using a visual analog scale. The consumption of analgesics was also recorded.RESULTS: There were 40 patients in the treatment group, and 30 patients in the control group. The pain scores at each time point, and analgesic consumption did not differ between the two groups. However,there were fewer patients in the treatment group than placebo group who required opioid infusion within the first 24 h (60% vs 37%, P = 0.053).

    Full Text Available Abstract Background Epidural analgesia with bupivacain, epinephrine and fentanyl provides excellent pain control after lumbar fusion surgery, but pruritus and motor block are frequent side effects. Theoretically epidural ropivacain combined with oral oxycodone could decrease the incidence of these side effects. The two regimens were compared in a prospective randomized trial. Patients and methods 150 patients (87 women treated with posterior instrumented lumbar fusion were included. The mean age was 51 +/- 11 years. 76 were randomized to bupivacain, epinephrine and fentanyl (group B and 74 to ropivacain and oxycodone (group R. Pruritus, motor block and pain were measured 6 hours after surgery, thereafter 6 times per day for 5 days. Any pain breakthrough episode was registered whenever it occurred. Results The epidural treatment could be performed in 143 patients (72 in group B and 71 in group R. Disturbing pruritus occurred in 53 patients in group B compared to 12 in group R (p Conclusions Pruritus could be reduced with a combination of epidural ropivacain and oral oxycodone, at the price of a slightly higher pain level. Ropivacaine was not found to be superior to bupivacaine with regard to motor blocks.

    The aim of this prospective randomized single blind study was to determine the depth of thermal damage to tonsillar tissue due to coblation, and to compare it with thermal damage to tonsillar tissue following conventional tonsillectomy; to correlate the depth of thermal damage to tonsillar tissue with the parameters of postoperative morbidity, to compare intraoperative blood loss, postoperative pain severity, time to resuming normal physical activity, and incidence of postoperative bleeding between two groups of tonsillectomized children aged up to 16 years. 72 children aged 3-16 years scheduled for tonsillectomy randomly assigned into two groups submitted either to conventional tonsillectomy with bipolar diathermy coagulation or to coblation tonsillectomy, with a 14-day follow up. Statistically significant differences were observed in the depth of thermal damage to tonsillar tissue (p < 0.001), intraoperative blood loss (p < 0.004), in postoperative pain severity (p < 0.05) and in time to resuming normal physical activity between the two groups (p < 0.001). There was no case of reactionary or secondary bleeding in either group. In this paper for the first time we have correlated postoperative morbidity and thermal tissue damage: less thermal damage is associated with less postoperative morbidity.

    2007-07-01

    Full Text Available Abstract Background: Lower respiratory tract infections like acute bronchitis, exacerbated chronic obstructive pulmonary disease and community-acquired pneumonia are often unnecessarily treated with antibiotics, mainly because of physicians' difficulties to distinguish viral from bacterial cause and to estimate disease-severity. The goal of this trial is to compare medical outcomes, use of antibiotics and hospital resources in a strategy based on enforced evidence-based guidelines versus procalcitonin guided antibiotic therapy in patients with lower respiratory tract infections. Methods and design: We describe a prospective randomized controlled non-inferiority trial with an open intervention. We aim to randomize over a fixed recruitment period of 18 months a minimal number of 1002 patients from 6 hospitals in Switzerland. Patients must be >18 years of age with a lower respiratory tract infections Discussion: Use of and prolonged exposure to antibiotics in lower respiratory tract infections is high. The proposed trial investigates whether procalcitonin-guidance may safely reduce antibiotic consumption along with reductions in hospitalization costs and antibiotic resistance. It will additionally generate insights for improved prognostic assessment of patients with lower respiratory tract infections. Trial registration: ISRCTN95122877

    Background: Radiofrequency (RF) is a minimally invasive target-selective technique that has been used with success for many years in the treatment of different pathologies, such as low back pain, trigeminal neuralgia, and others. Aim: The aim of this study is to compare different mode of RF - continuous RF (CRF) versus pulsed RF (PRF) along with steroid in the management of low back pain of discogenic origin. Setting and Design: Prospective, randomized, double-blind trial. Materials and Methods: Forty patients with chronic discogenic low back pain were randomized to receive CRF plus intradiscal triamcinolone 40 mg (Group 1) or to receive PRF plus intradiscal triamcinolone 40 mg (Group 2). Outcome measured includes immediate as well as long-term pain relief using visual analog scale, the Oswestry Disability Index and straight leg raising test. Statistical Analysis: The continuous variables were compared by one-way analysis of variance test. Discrete variables were compared by Fisher's exact test/Chi-square test/Student's t-test, whichever appropriate. The value of P PRF was insignificant. Conclusion: CRF with steroid seems to be better for treatment of chronic discogenic low back pain than PRF with steroid. PMID:27746559

    To determine the need for pre-treatment stenting in patients undergoing extracorporeal shockwave lithotripsy (ESWL) for ureteral stones sized 4-10 mm. A prospective randomized study was conducted between September 2009 and March 2011. Included 156 patients randomized in stented and non-stented groups and underwent a maximum of 3 ESWL sessions. Radiographic follow-up was used to assess the stone fragmentation and clearance. Results were compared in terms of stone-free rates, post-treatment morbidity and complications. Overall efficacy was 76.9%. Stone-free rates were statistically significantly lower (P = 0.026) in the stented group (68.6%) compared to the non-stented ones (83.7%). Furthermore, stenting was significantly correlated with post-treatment lower urinary tract symptoms (P ≤ 0.001), need for more ESWL sessions (P = 0.019) and possibility for operation due to ESWL failure (P = 0.026). A multivariate analysis was conducted to identify the parameters which may predict complete stone removal after ESWL. Stone size (P = 0.026), stone location (P = 0.011) and stenting (P = 0.007) were the most significant factors. ESWL is an efficient and safe treatment for 4- to 10-mm ureteral stones. Pre-treatment stenting is limiting stone-free rates and is significantly influencing post-ESWL morbidity and quality of life in a negative manner, while it contributes minimally to the prophylaxis of complications.

    To determine the efficacy and safety of high-power holmium: yttrium aluminum-garnet (Ho:YAG) laser lithotripsy for multitract modified minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of patients with large staghorn renal calculi. A randomized, prospective study was conducted. Two-hundred seventy-three consecutive patients (291 renal units) with large staghorn renal calculi were randomized to undergo multitract MPCNL with 30-W low-power or 70-W high-power Ho:YAG laser lithotripsy. Both groups were compared in terms of perioperative findings and postoperative outcomes, including procedure time, stone-free rate, length of hospital stay, transfusion rates, renal function recovery, and other complications. The average patient age was 49.2 years (range 22-73) and mean stone size was 5.54±0.7 cm. The 2 groups had some comparable perioperative findings and outcome, including tracts required per operated renal unit (n), blood loss, postoperative fever, postoperative hospital stay, stone-free rate, and improvement of operated renal function. The operation time in the high-power group was significantly shorter than that in the low-power group (129.20±17.2 vs 105.18±14.2, Ppower Ho:YAG laser lithotripsy can greatly decrease the operative time without increasing the intraoperative complications or delaying postoperative renal function recovery when compared with low-power Ho:YAG laser lithotripsy.

    2016-09-01

    Many randomized controlled trials (RCTs) of neuropsychiatric conditions involve cognitive outcome measures; however, validity of cognitive data relies on adequate effort during testing, and such screening is seldom performed. Given well-established rates of 10 to 30% poor effort in clinical settings, this is not a trivial concern. This preliminary study evaluated effort during cognitive testing in an RCT of omega-3 supplementation to reduce suicidality in a high-risk psychiatric population. An interim analysis of sustained attentions measures from the Connors Performance Test (CPT-2) at baseline for the first 60 participants was conducted. Previously validated cut points to detect insufficient effort on the CPT-2 were applied. At baseline, 12% (7) were identified as giving poor effort. Follow-up analyses indicated less psychiatric distress and suicidality among those who gave poor effort. Results suggest comparable likelihood of a poor effort on cognitive testing in clinical and RCT participation. Reduced psychiatric distress in the poor effort group raises concern regarding interpretation of other measures. The importance of screening cognitive data for effort in RCTs is highlighted. Future studies will examine effort at follow-up visits, and explore relationships to attrition, adherence, and response to treatment. Copyright © 2016 John Wiley & Sons, Ltd.

    The paper describes the agent-based model usage to evaluate the dynamics and the perspectives of alternative energy adopting in the Eastern regions of Russia. It includes a brief review of the agent-based models that can be used for estimation of alternatives in the process of transition to “green” economics. The authors show that active usage of solar energy in Russia is possible at the rural household level, when the climate conditions are appropriate. Adoption of solar energy sources decreases the energy production based on the conventional sources and improves the quality of environment in the regions. A complex regional multi-agent model is considered in this paper. The model consists of several private models and uses GIS technologies. These private models are a demographic and migration model of the region and a diffusion of the innovations model. In these models, agents are humans who live within the boundaries of the agents-municipalities, and agents as well are large-scale producers of electricity that pollutes the environment. Such a structure allows us to determine the changes in the demand for electricity generated by traditional sources. A simulation software will assist to identify the opportunities for implementation of alternative energy sources in the Eastern regions of Russia.

    Background Conventional pharmacotherapies and psychotherapies for major depression are associated with limited adherence to care and relatively low remission rates. Yoga may offer an alternative treatment option, but rigorous studies are few. This randomized controlled trial with blinded outcome assessors examined an 8-week hatha yoga intervention as mono-therapy for mild-to-moderate major depression. Methods Investigators recruited 38 adults in San Francisco meeting criteria for major depression of mild-to-moderate severity, per structured psychiatric interview and scores of 14–28 on Beck Depression Inventory-II (BDI). At screening, individuals engaged in psychotherapy, antidepressant pharmacotherapy, herbal or nutraceutical mood therapies, or mind-body practices were excluded. Participants were 68% female, with mean age 43.4 years (SD = 14.8, range = 22–72), and mean BDI score 22.4 (SD = 4.5). Twenty participants were randomized to 90-minute hatha yoga practice groups twice weekly for 8 weeks. Eighteen participants were randomized to 90-minute attention control education groups twice weekly for 8 weeks. Certified yoga instructors delivered both interventions at a university clinic. Primary outcome was depression severity, measured by BDI scores every 2 weeks from baseline to 8 weeks. Secondary outcomes were self-efficacy and self-esteem, measured by scores on the General Self-Efficacy Scale (GSES) and Rosenberg Self-Esteem Scale (RSES) at baseline and at 8 weeks. Results In intent-to-treat analysis, yoga participants exhibited significantly greater 8-week decline in BDI scores than controls (p-value = 0.034). In sub-analyses of participants completing final 8-week measures, yoga participants were more likely to achieve remission, defined per final BDI score ≤ 9 (p-value = 0.018). Effect size of yoga in reducing BDI scores was large, per Cohen’s d = -0.96 [95%CI, -1.81 to -0.12]. Intervention groups did not differ significantly in 8-week change scores for

    We sought to investigate whether application of topical tetracycline has a limiting effect on seroma formation in patients undergoing hernia repair using a polypropylene mesh. This study was conducted in 96 patients undergoing an elective groin hernia repair. Patients were randomized and divided into 2 groups. After the graft was placed, and before external oblique muscle aponeurosis was closed, 5 mL tetracycline was administered on the graft in the tetracycline group (tetra group, n = 50), and 5 mL isotonic saline was administered in the control group (n = 46) without putting in a drain. Seroma checks via surface ultrasonography were done. Seroma amounts measured on the first day were significantly higher in the tetra group (P = 0.04). There were no significant differences regarding seroma measurements on the seventh day or in the first and second months. Topical tetracycline application has no limiting effect on seroma formation after a groin hernia operation.

    To compare the efficacy, tolerance, and safety of manual manipulation at day 7 to day 1 following collagenase Clostridium histolyticum (CCH) injection for Dupuytren contracture. Eligible patients were randomized to manipulation at day 1 versus day 7 following CCH injection. Preinjection, premanipulation, postmanipulation, and 30-day follow-up metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint contractures were measured. Pain scores were recorded at each time point. Data were stratified per cohort based on primary joint treated (MCP vs PIP). Means were compared using paired and unpaired t-tests. Forty-three patients with 46 digits were eligible and were randomized to 1-day (22 digits) and 7-day (24 digits) manipulation. For MCP joints, there were no significant differences in flexion contractures between 1- and 7-day cohorts for initial (47° vs 46°), postmanipulation (0° vs 2°), or 30-day follow-up (1° vs 2°) measurements. Premanipulation, the residual contracture was significantly lower in the 7-day group (23° vs 40°). For PIP joints, there were no significant differences between 1- and 7-day cohorts for initial (63° vs 62°), premanipulation (56° vs 52°), postmanipulation (13° vs 15°), or 30-day (14° vs 16°) measurements. There were no significant differences in pain or skin tears between the 2 groups. No flexor tendon ruptures were observed. The effectiveness of CCH in achieving correction of Dupuytren contractures was preserved when manipulation was performed on day 7, with no differences in correction, pain, or skin tears. These data suggest that manipulation can be scheduled at the convenience of the patient and surgeon within the first 7 days after injection. Therapeutic I.

    Full Text Available Background and Design: The definition of emergent diseases includes potentially risky diseases that need urgent medical intervention. Diagnostic and therapeutic processes are managed mostly at ourpatient setting in dermatology. Therefore, it is unclear that which diseases are real emergencies and which patients apply urgently. There are a few studies assessing this topic. Our aim was to evaluate patients referred to our clinic urgently, and to review the concept of ‘‘real dermatologic emergency’’ by comparing dermatologic emergency patients and outpatients. Material and Method: A total of 800 patients (400 urgent patients, 400 outpatients were included. Demographic features, complaints, disease duration and severity, whether the disease occurs for the first time were questionned, application time and diagnosis were recorded. The opinions of patients and physicians were inquired about why they thought that the disease was emergent. Results: Most common skin diseases were acute urticaria-angioedema, contact dermatitis, and insect bite in emergency patients; acne vulgaris, verruca and tinea pedis in outpatients. Itching was more common in emergency patients. Emergency patients' complaints were more severe than those of outpatients. Patients who experience disease first time applied to emergency service more than others. Emergency patients had a shorter disease duration than outpatients. Patients and physicians revealed different reasons and criteria about the urgency of the diseases. 93.5% of patients and 49% of physicians thought that existing disease was emergent. Conclusion: Our data reveal that the concept of dermatologic emergency is unsettled. It changes according to socio-cultural, personal features and to the present health system. Determination of the main criteria of the definition of “dermatologic urgent”, and training of dermatologists, emergency centers’physicians and also of patients in this regard seem to be a necessity

    Introduction: Pneumothorax (PTX) occurs commonly in trauma patients and is confirmed by examination and radiography. Thoracic ultrasound (VIS) has been suggested as an alternative method for rapidly diagnosing PTX when X-ray is unavailable as in rural, military, or space flight settings; however, its accuracy and specificity are not known. Methods: We evaluated the accuracy of thoracic U/S detection of PTX compared to radiography in stable, emergency patients with a high suspicion of PTX at a Level-l trauma center over a 6-month period. Following University and NASA Institutional Review Board approval, informed consent was obtained from patients with penetrating or blunt chest trauma, or with a history consistent with PTX. Whenever possible, the presence or absence of the " lung sliding" sign or the "comet tail" artifact were determined by U/S in both hemithoraces by residents instructed in thoracic U/S before standard radiologic verification of PTX. Results were recorded on data sheets for comparison to standard radiography. Results: Thoracic VIS had a 94% sensitivity; two PTX could not be reliably diagnosed due to subcutaneous air; the true negative rate was 100%. In one patient, the VIS exam was positive while X ray did not confirm PTX; a follow-up film 1 hour later demonstrated a small PTX. The average time for bilateral thoracic VIS examination was 2 to 3 minutes. Conclusions: Thoracic ultrasound reliably diagnoses pneumothorax. Presence of the "lung sliding" sign conclusively excludes pneumothorax. Expansion of the FAST examination to include the thorax should be investigated.

    Purpose the purpose of this study was to evaluate whether treating partial-thickness articular-sided tears of the upper subscapularis (SSC) tendon with a dedicated suture anchor would result in an internal rotation strength improvement compared with simple shaving of the SSC tendon and footprint. Methods twenty-six patients with a limited SSC tendon tear (equal or inferior to the most superior centimeter) in association with a posterosuperior cuff lesion were prospectively randomized to two treatments: repair with a dedicated suture anchor versus shaving of the tendon and footprint. The patients also underwent long head of the biceps (LHB) treatment and posterosuperior cuff tear repair. In each patient the following parameters were measured both preoperatively and at a minimum follow-up of 2.5 years: strength in internal rotation in the bear-hug testing position (using a digital tensiometer), DASH score and Constant scores. MRI assessment of tendon healing was performed at the final follow-up. Results twenty of the 26 patients (76%) were reviewed after a mean follow-up time of 42 months: 11 patients had undergone SSC tendon repair and nine simple shaving. At final follow-up no significant differences were found between the repaired and shaving group in strength in internal rotation (9.5 ± 3.8 kg versus 10.3±5.4 kg; p=0.7). The DASH score and Constant score also failed to show significant differences between the two groups. Furthermore, no significant difference in SSC tendon healing rate was observed on MRI evaluation. Conclusions partial-thickness articular-sided tear of the upper SSC tendon in association with a posterosuperior rotator cuff repair and LHB treatment, when limited to the superior centimeter of the SSC tendon, shows a comparable performance in terms of strength in internal rotation either after simple shaving or a tendon-to-bone repair. Level of evidence Level II, prospective comparative study. PMID:26889466

    Previously reported results of a prospective, randomized placebo-controlled study showed that the pollen extract (Cernilton) significantly improved total symptoms, pain, and quality of life in patients with inflammatory prostatitis/chronic pelvic pain syndrome (CP/CPPS) without severe side effects. A phytotherapeutic agent, Eviprostat, is reportedly effective in a rat model of nonbacterial prostatitis. The aim of the present study was to compare the efficacy and safety of Eviprostat to that of the pollen extract in the management of CP/CPPS. The patients with category III CP/CPPS were randomized to receive either oral capsules of Eviprostat (two capsules, q 8 h) or the pollen extract (two capsules, q 8 h) for 8 weeks. The primary endpoint of the study was symptomatic improvement in the NIH Chronic Prostatitis Symptom Index (NIH-CPSI). Participants were evaluated using the NIH-CPSI and the International Prostate Symptom Score (IPSS) at baseline and after 4 and 8 weeks. In the intention-to-treat analysis, 100 men were randomly allocated to Eviprostat (n = 50) or the pollen extract (n = 50). Response (defined as a decrease in the NIH-CPSI total score by at least 25 %) in the Eviprostat group and the pollen extract group was 88.2 and 78.1 %, respectively. There was no significant difference in the total, pain, urinary, and quality of life (QOL) scores of the NIH-CPSI between the two groups at 8 weeks. This was also the case with the total, voiding, and storage symptoms of the IPSS. There were no severe adverse events observed in any patients in this study. Both the pollen extract and Eviprostat significantly reduced the symptoms of category III CP/CPPS without any adverse events. Eviprostat may have an identical effect on category III CP/CPPS compared the pollen extract. The study was registered with the University Hospital Medical Information Network Clinical Trials Registry in Japan (UMIN000019618); registration date: 3 November 2015.

    Sedation with propofol alone during gastroscopy has many side effects. Etomidate has advantages in terms of circulation and respiration compared to propofol. We hypothesized that etomidate plus propofol during gastroscopy would be more safe and effective than propofol alone. Four hundred (n = 400) patients were randomly divided into a propofol group (P group) and a etomidate plus propofol group (EP group). The P group was given the first dose of 1 % propofol 1 mg/kg before gastroscopy, and the EP group was given 1 % propofol 0.5 mg/kg plus etomidate 0.1 mg/kg. Repeated doses of 10-20 mg propofol or 5-10 mg propofol plus 1-2 mg etomidate were administered to maintain an adequate level of sedation. The sedation depth was maintained by bispectral index value of 40-60. The EP group had a lower incidence of systolic hypotension (13.0 vs. 32.5 %; P propofol had few effects on respiration and circulation in patients undergoing gastroscopy and was more safe and effective than propofol alone.

    Full Text Available INTRODUCTION: Combining minimal invasive surgical and lesser invasive anesthesia technique reduces morbidity and mortality. The aim of the study is to compare spinal anesthesia with the gold standard general anesthesia for elective laparoscopic cholecystectomy. MATERIALS & METHODS: 60 healthy patients were randomized under spinal anesthesia (n=30 & General Anesthesia (n=30 . Hyperbaric 3ml bupivacaine plus 25mcg fenta nyl was administered for spinal group and conventional general anesthesia for GA group. Intraoperative parameters and post - operative pain and recovery were noted. Under spinal group any intraoperative discomfort were taken care by reassurance , drugs or con verted to GA. Questionnaire forms were provided for patients and surgeons to comment about the operation. RESULTS: None of the patients had significant hemodynamic and respiratory disturbance except for transient hypotension and bradycardia. Operative time was comparable. 6patients under spinal anesthesia had right shoulder pain , 2 patients were converted to GA and 4 patients were managed by injection midazolam and infiltration of lignocaine over the diaphragm. There was significant post - operative pain reli ef in spinal group. All the patients were comfortable and surgeons satisfied. CONCLUSION: Spinal anesthesia is adequate and safe for laparoscopic cholecystectomy in otherwise healthy patients and offers better postoperative pain control than general anesth esia without limiting recovery , but require cooperative patient , skilled surgeon , a gentle surgical technique and an enthusiastic anesthesiologist

    Male circumcision is the most frequently performed procedure by urologists. Safety and efficacy of the circumcision procedure requires continual improvement. In the present study, we investigated the safety and efficacy of a new male circumcision technique involving the use of a circular stapler. In total, 879 consecutive adult male patients were randomly divided into 2 groups: 441 underwent stapler circumcision, and 438 underwent conventional circumcision. The operative time, pain score, blood loss volume, healing time, treatment costs, and postoperative complications were compared between the two groups. The operative time and blood loss volume were significantly lower in the stapler group than in the conventional group (6.8 ± 3.1 vs 24.2 ± 3.2 min and 1.8 ± 1.8 vs 9.4 ± 1.5 mL, respectively; Pcircumcision required removal of residual staple nails. Overall, the present study has shown that stapler circumcision is a time-efficient and safe male circumcision technique, although it requires further improvement.

    Objectives The epilepsy treatment gap is largest in resource-poor countries. We evaluated the efficacy of a 1-day health education program in a rural area of Kenya. The primary outcome was adherence to antiepileptic drugs (AEDs) as measured by drug levels in the blood, and the secondary outcomes were seizure frequency and Kilifi Epilepsy Beliefs and Attitudes Scores (KEBAS). Methods Seven hundred thirty-eight people with epilepsy (PWE) and their designated supporter were randomized to either the intervention (education) or nonintervention group. Data were collected at baseline and 1 year after the education intervention was administered to the intervention group. There were 581 PWE assessed at both time points. At the end of the study, 105 PWE from the intervention group and 86 from the nonintervention group gave blood samples, which were assayed for the most commonly used AEDs (phenobarbital, phenytoin, and carbamazepine). The proportions of PWE with detectable AED levels were determined using a standard blood assay method. The laboratory technicians conducting the assays were blinded to the randomization. Secondary outcomes were evaluated using questionnaires administered by trained field staff. Modified Poisson regression was used to investigate the factors associated with improved adherence (transition from nonoptimal AED level in blood at baseline to optimal levels at follow-up), reduced seizures, and improved KEBAS, which was done as a post hoc analysis. This trial is registered in ISRCTN register under ISRCTN35680481. Results There was no significant difference in adherence to AEDs based on detectable drug levels (odds ratio [OR] 1.46, 95% confidence interval [95% CI] 0.74–2.90, p = 0.28) or by self-reports (OR 1.00, 95% CI 0.71–1.40, p = 1.00) between the intervention and nonintervention group. The intervention group had significantly fewer beliefs about traditional causes of epilepsy, cultural treatment, and negative stereotypes than the

    To prospectively assess the efficiency of a standardized diagnostic approach, compared to an open strategy, for the etiologic diagnosis of uveitis. Noninferiority, prospective, multicenter, clustered randomized controlled trial. Consecutive patients with uveitis, who visited 1 of the participating departments of ophthalmology, were included. In the standardized group, all patients had a minimal evaluation regardless of the type of uveitis (complete blood count, erythrocyte sedimentation rate, C-reactive protein, tuberculin skin test, syphilis serology, and chest radiograph) followed by more complex investigations according to ophthalmologic findings. In the open group, the ophthalmologist could order any type of investigation. Main outcome was the percentage of etiologic diagnoses at 6 months. Nine hundred and three patients with uveitis were included from January 2010 to May 2013 and the per-protocol population comprised 676 patients (open 373; standardized 303). Mean age at diagnosis was 46 years. Anatomic distribution of uveitis was as follows: anterior (60.8% and 72.3%, P = .0017), intermediate (11.7% and 12.3%, P = .8028), posterior (17.8% and 8.2%, P = .0004), and panuveitis (15.3% and 15.2%, P = .9596). An etiologic diagnosis was established in 54.4% of cases in the open group and 49.5% in the standardized group (P = .2029). The difference between both strategies (standardized minus open) was -4.9% (95% CI [-12.5%; 2.6%]). There were more investigations in the open group than in the standardized group (5371 vs 3759, P uveitis, although its noninferiority cannot be proved. Copyright © 2017 Elsevier Inc.

    We previously reported on the safety and efficacy of bipolar hemostatic forceps for treating nonvariceal upper gastrointestinal (UGI) bleeding. However, no prospective or randomized studies have evaluated the efficacy of bipolar hemostatic forceps. The aim of this study was to evaluate the hemostatic efficacy of using bipolar hemostatic forceps compared with the hemostatic efficacy of the commonly used method of endoscopic hemoclipping for treating nonvariceal UGI bleeding. A total of 50 patients who required endoscopic hemostasis for UGI bleeding were divided into two groups: those who underwent endoscopic hemostasis using bipolar hemostatic forceps (Group I) and those who underwent endoscopic hemostasis by endoscopic hemoclipping (Group II). We compared the two groups in terms of hemostasis success rate and time required to achieve hemostasis and stop recurrent bleeding. All (100 %) of 27 patients in Group I and 18 (78.2 %) of 23 patients in Group II were successfully treated using bipolar hemostatic forceps or by endoscopic hemoclipping alone, respectively, indicating a significantly higher success rate for Group I than for Group II (p bleeding. Bipolar hemostatic forceps was more effective than endoscopic hemoclipping for treating nonvariceal UGI bleeding.

    This study aimed to compare the effect of nimesulide and ketoprofen on inflammatory parameters related to the surgical removal of third molars. A split-mouth, prospective, randomized, double-blind study was conducted in patients undergoing removal of four third molars. Eighteen eligible patients were allocated to one of two groups to receive treatment two times a day with either ketoprofen 100 mg or nimesulide 100 mg for a period of 3 days. The rescue medication intake (number) and pain intensity were evaluated at 6, 12, 24, and 48 h, and at 7 days postoperatively. Swelling and maximum mouth opening were evaluated at 24 h, 72 h, and 7 days postoperatively. The peak pain score occurred at 6h after surgery in the nimesulide group and at 12h in the ketoprofen group. There was no statistically significant difference between the groups, although pain relief was observed after 48 h in the nimesulide group and after 7 days in the ketoprofen group. For each group, there was a statically significant difference in pain scores among the studied periods (PKetoprofen and nimesulide were effective at controlling pain, swelling, and trismus after the surgical removal of third molars.

    Aim of this work is to find out whether the symptoms attributable to adenoid hypertrophy in adolescents may be treated with intranasal mometasone furoate (MF) application. To learn if adenoid hypertrophy in adolescents may decrease in size with intranasal MF. A prospective, double blind, randomized, cross-over study was conducted in 28 subjects (12-18 years) with adenoidal hypertrophy. Subjects used intranasal MF or placebo for a duration of 6 weeks with a wash out period of 3 weeks. Subjective symptoms and adenoid size were evaluated. At the initiation of the study, there was no significant difference between the mean symptom scores for any of the sinonasal symptoms between the two treatment groups. There was significant improvement in total subjective symptoms (nasal blockage, rhinorrhea, cough, snoring and disruption of quality of life scores) with MF compared with placebo. Analysis of the symptoms separately showed a significant positive effect of MF on all symptoms except for rhinorrhea. Nasal endoscopic evaluation failed to demonstrate any difference in the reduction of the adenoid size between the two groups. MF has significant advantage over placebo for the symptoms attributable to adenoid hypertrophy in adolescents.

    Purpose: Periprostatic nerve block (PNB) is the most common anesthesia technique used before prostate biopsy. However, needle punctures for anesthetic infiltration may be painful and cause higher infectious complications. We assessed whether addition of rectal lidocaine gel would improve its efficacy. We also investigated the efficacy and safety of tramadol, a codeine derivative, as a noninvasive method. Materials and Methods: A total of 300 patients who underwent prostate biopsies were randomized into 4 groups of controls, PNB, perianal/intrarectal lidocaine gel plus PNB and tramadol. Pain was assessed with a numeric analog scale. Results: Each group consisted of 75 patients, and there was a statistically significant difference among pain scores (p = 0.001). Mean pain scores were 4.63 for controls, 2.57 for PNB, 2.03 for infiltration plus gel group and 3.11 for tramadol. Pain and discomfort were least in PNB plus gel arm. The difference of pain score between PNB alone and tramadol group did not reach statistical significance. Infectious complications were higher in the combination group, whereas there were no complications with tramadol. Conclusions: Any form of analgesia/anesthesia was superior to none. The combination of PNB plus gel provided significantly better analgesia compared to PNB alone or tramadol. If this can be duplicated in other trials, the combination may be accepted as the new gold standard of anesthesia for prostate biopsy. The efficacy of tramadol was similar to that of PNB, and was free of complications. Therefore, tramadol may have a role before prostate biopsy, which needs to be explored. (author)

    Purpose To determine whether shortening the infusion duration of high-dose methotrexate (HDMTX; 1 g/m2) affects the in vivo accumulation of active methotrexate polyglutamates (MTXPG1-7) in leukemia cells and whether this differs among major acute lymphoblastic leukemia (ALL) subtypes. Methods From June 2000 through October 2007, 356 children with ALL were randomly assigned to receive initial single-agent treatment with HDMTX (1 g/m2) as either a 24-hour infusion or a 4-hour infusion at two pediatric hospitals in the United States. The primary outcome measures were the accumulation of MTXPG1-7 in leukemia cells and the antileukemic effects (eg, inhibition of de novo purine synthesis in bone marrow ALL cells, and decrease in circulating ALL cells). Results The 24-hour infusion resulted in significantly higher amounts of MTXPG1-7 in bone marrow leukemia cells (median: 1,695 v 1,150 pmol/109 cells, P = .0059), and better antileukemic effects. The 24-hour infusion had the greatest effect on MTXPG1-7 accumulation in hyperdiploid ALL (median: 3,919 v 2,417 pmol/109 cells, P = .0038); T-cell ALL exhibited smaller differences in MTXPG1-7 but greater antileukemic effects with the longer infusion (median decrease in leukemia cells: 88.4% v 51.8%, P = .0075). In contrast, infusion duration had no significant impact on MTXPG1-7 accumulation or antileukemic effects in ALL with the t(12;21)/(ETV6-RUNX1) chromosomal translocation. Conclusion Shortening the infusion time of HDMTX reduces accumulation of active methotrexate in leukemia cells and decreases antileukemic effects, with differing consequences among major ALL subtypes.

    Full Text Available : OBJECTIVE: Controlled hypotension is commonly used to achieve a bloodless operative field which is needed for successful FESS. This study was carried out to assess the hypotensive effect of dexmedetomidine (DEX during FESS. METHODS: Fifty ASA grades I and II patients of either sex aged 20–50 years undergoing FESS were randomly divided into two groups of 25 each. Group D received 10–15 min prior to induction of anesthesia 1 μg/kg IV bolus DEX diluted in 10 ml of normal saline over 10 min. Immediately thereafter an infusion of 0.4 μg/kg/hr of DEX commenced. Group C received placebo bolus and infusion of saline at a rate similar to DEX in Group D. Standard anesthetic technique was used. The surgical field was assessed using Average Category Scale and average blood loss was calculated. Hemodynamic variables (MAP and HR; emergence time and total recovery from anesthesia (Aldrete score ≥9 were recorded. RESULT: Group D reached the desired MAP (55-65 mmHg. In group D patients the average MAP was 55.9±5.3 mm of Hg, where as in group C it was 86.2±11.4 mm of Hg. Patients in group D had a better surgical field, and the duration of surgery was significantly reduced(78.34±16.7mins in group D vs 103.2±113.1 mins in group C The mean awakening time was significantly reduced in patients of Group D (9.1±2.7 mins in group D vs12.8±2.2 mins in group C when compared to patients of Group C. CONCLUSION: This study demonstrated that dexmedetomidine is a safe agent for controlled hypotension and is effective in providing ideal surgical field during FESS.

    The aim of the study was to compare the outcomes of regenerative endodontic treatment (RET) and apexification on immature permanent teeth with pulp necrosis and apical periodontitis. A total of 118 patients (118 teeth) were recruited and randomly assigned to either RET or apexification treatment. Each treatment group was divided into 2 subgroups according to the etiology: dens evaginatus or trauma. Clinical symptoms and complications were recorded, and cone-beam computed tomographic imaging with a limited field of view was used to measure the change of root length, root thickness, and apical foramen size at the 12-month follow-up. The t test/rank sum test and Fisher exact test were applied to compare the change of root morphology between RET and apexification. One hundred three of 118 cases were completed at the 12-month follow-up. The survival rate was 100% for both treatment groups. All cases were asymptomatic with apical healing. The RET group showed a significant increase in root length and root thickness compared with the apexification group (P < .05). In the RET group, the cases caused by dens evaginatus achieved increased root length and root thickness compared with those caused by trauma (P < .05). RET and apexification achieved a comparable outcome in regard to the resolution of symptoms and apical healing. RET showed a better outcome than apexification regarding increased root thickness and root length. The etiology had an impact on the outcome of RET. Dens evaginatus cases showed better prognoses than trauma cases after RET. Copyright © 2017 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    Full Text Available Background: Traditionally, conservative treatment of thoracolumbar (TL burst fractures without neurologic deficit has encompassed the application of an extension brace. However, their effectiveness on maintaining the alignment, preventing posttraumatic deformities, and improving back pain, disability and quality of life is doubtful. Objective: The objective was to identify and summarize the evidence from randomized controlled trials (RCTs to determine whether bracing patients who suffer TL fractures adds benefices to the conservative manage without bracing. Materials and Methods: Seven databases were searched for relevant RCTs that compared the clinical and radiological outcomes of orthosis versus no-orthosis for TL burst fractures managed conservatively. Primary outcomes were: (1 Loss of kyphotic angle; (2 failure of conservative management requiring subsequent surgery; and (3 disability and pain outcomes. Secondary outcomes were defined by health-related quality of life and in-hospital stay. Results: Based on predefined inclusion criteria, only two eligible high-quality RCTs with a total of 119 patients were included. No significant difference was identified between the two groups regarding loss of kyphotic angle, pain outcome, or in-hospital stay. The pooled data showed higher scores in physical and mental domains of the Short-Form Health Survey 36 in the group treated without orthosis. Conclusion and Recommendation: The current evidence suggests that orthosis could not be necessary when TL burst fractures without neurologic deficit are treated conservatively. However, due to limitations related with number and size of the included studies, more RCTs with high quality are desirable for making recommendations with more certainty.

    To assess the optimal surgical approach and costs for patients hospitalized with septic bursitis. From May 1, 2011, through December 24, 2014, hospitalized patients with septic bursitis at University of Geneva Hospitals were randomized (1:1) to receive 1- vs 2-stage bursectomy. All the patients received postsurgical oral antibiotic drug therapy for 7 days. Of 164 enrolled patients, 130 had bursitis of the elbow and 34 of the patella. The surgical approach used was 1-stage in 79 patients and 2-stage in 85. Overall, there were 22 treatment failures: 8 of 79 patients (10%) in the 1-stage arm and 14 of 85 (16%) in the 2-stage arm (Pearson χ(2) test; P=.23). Recurrent infection was caused by the same pathogen in 7 patients (4%) and by a different pathogen in 5 (3%). Outcomes were better in the 1- vs 2-stage arm for wound dehiscence for elbow bursitis (1 of 66 vs 9 of 64; Fisher exact test P=.03), median length of hospital stay (4.5 vs 6.0 days), nurses' workload (605 vs 1055 points), and total costs (Sw₣6881 vs Sw₣11,178; all Pbursitis requiring hospital admission, bursectomy with primary closure, together with antibiotic drug therapy for 7 days, was safe, effective, and resource saving. Using a 2-stage approach may be associated with a higher rate of wound dehiscence for olecranon bursitis than the 1-stage approach. Clinicaltrials.gov Identifier: NCT01406652.

    Central line catheter insertion is a complex procedure with a high cognitive load for novices. Providing a prepackaged all-inclusive kit is a simple measure that may reduce the cognitive load. We assessed whether the use of prepackaged all-inclusive central line insertion kits reduces procedural mistakes during central line catheter insertion by novices. Thirty final year medical students and recently qualified physicians were randomized into two equal groups. One group used a prepackaged all-inclusive kit and the other used a standard kit containing only the central vein catheter and all other separately packaged components provided in a materials cart. The procedure was videotaped and analyzed by two blinded raters using a checklist. Both groups performed central line catheter insertion on a manikin, assisted by nursing students. The prepackaged kit group outperformed the standard kit group in four of the five quality indicators: procedure duration (26:26 ± 3:50 min vs. 31:27 ± 5:57 min, p = .01); major technical mistakes (3.1 ± 1.4 vs. 4.8 ± 2.6, p = .03); minor technical mistakes (5.2 ± 1.7 vs. 8.0 ± 3.2, p = .01); and correct steps (83 ± 5% vs. 75 ± 11%, p = .02). The difference for breaches of aseptic technique (1.2 ± 0.8 vs. 3.0 ± 3.6, p = .06) was not statistically significant. Prepackaged all-inclusive kits for novices improved the procedure quality and saved staff time resources in a controlled simulation environment. Future studies are needed to address whether central line kits also improve patient safety in hospital settings.

    The aim of this study was to determine if local injection of bupivacaine after hemorrhoidal banding causes a decrease in pain and in the incidence of associated symptoms. After hemorrhoidal banding, patients were randomly assigned to receive a local injection of bupivacaine with 1:200,000 epinephrine, an injection of normal saline, or no injection, just superior to each band. Pain was graded by the patient and by the study nurse within 30 minutes, and any associated symptoms were recorded. At intervals 6, 24, and 48 hours postbanding, the patient recorded pain, limitation of activities, and analgesic requirements. Associated symptoms while at home were recorded. Of 115 patients studied, 42 received bupivacaine injection, 42 received normal saline injection, and 31 received no injection. In patients receiving bupivacaine compared with no injection, within 30 minutes postbanding there was a significant reduction in pain graded by the patient (P = 0.000002) and by the nurse (P = 0.000005) and a significant reduction in incidence of nausea (P = 0.01) and shaking (P = 0.008). However, in the bupivacaine group compared with the other two groups, at the intervals of 6, 24, and 48 hours postbanding there was no sustained reduction in the severity of pain and no reduction in analgesic requirements or limitation of normal activities. In the week after banding, there was no difference between groups in symptoms of nausea, shaking, lightheadedness, urinary retention, or bleeding. Bupivacaine injection may be useful for reducing pain and associated symptoms long enough to tolerate a trip home from the outpatient department but does not show a sustained effect.

    A number of recent studies have been devoted to the uncertainty estimation of reactor calculation parameters by the GRS (Generation Random Sampled) method. This method is based on direct sampling input data resulting in formation of random sets of input parameters which are used for multiple calculations. Once these calculations are performed, statistical processing of the calculation results is carried out to determine the mean value and the variance of each calculation parameter of interest. In our study this method is used to estimate the uncertainty of calculation parameters (keff, power density, dose rate) of a prospective sodium-cooled fast reactor. Neutron transport calculations were performed by the nodal diffusion code TRIGEX and Monte Carlo code MMK.

Study Design: In this randomized controlled trial, 15 patients undergoing extraction of at least four teeth were selected. In each patient after atraumatic extractions, one socket was grafted with WTA, second with DA, third with FDBA, and fourth was left ungrafted (control site. All the sites were covered with chorion membrane. To estimate three-dimensional alveolar crest changes, cone beam computed tomography scans were taken immediately after grafting and 4 months postoperatively. Bone biopsies using 3 mm trephine bur were obtained from four patients at the time of implant placement and evaluated histologically. Results: Clinically uneventful healing was observed at all sites. Compared to other sites, WTA and DA consistently showed superior results demonstrating least reduction in alveolar crest height and width which was statistically significant (P < 0.05. Between WTA and DA sites, there was no statistically significant difference. Histological analysis also confirmed more new bone formation at WTA and DA sites. Conclusions: Rather than disposing extracted human teeth as a biomedical waste (common practice, they can be collected from suitable systemically healthy donors. With the help of tissue bank, they can be processed into an allograft, serving as an

    The study was aimed to the evaluation of efficacy and safety of cefixime and amoxicillin/clavulanate in the treatment of asymptomatic bacteriuria in pregnant women. A prospective, multicenter, randomized study that included 112 pregnant women with asymptomatic bacteriuria was performed. 58 women were randomized in group 1 (cefixime [suprax solutab] 400 mg 1 time a day, 7 days), 54 women were included in group 2 (amoxicillin/clavulanate [amoksiklav] 625 mg 3 times a day, 7 days). The average age of the patients in group 1 was 25.2 +/- 6.6; in group 2--26.6 +/- 5.8 years. Physical examination, evaluation of complaints, collection of data on adverse reactions, and bacteriological analysis of urine were performed after enrollment in the study at visit 2 (day 10 +/- 1) and 3 (day 35 +/- 2). Comparable effectiveness of cefixime and amoxicillin/clavulanate in the treatment of asymptomatic bacteriuria in pregnant women was found. Eradication of the pathogen and sustained bacteriological response were observed in 94.8 and 92.7% of women treated with cefixime, and in 98.2 and 92.5% of women treated with amoxicillin/clavulanate, respectively (P > 0.05). At the same time, the use of amoxicillin/clavulanate compared with cefixime significantly higher was followed by the development of adverse reactions (13% and 1.7; respectively; P = 0.02). Seven-day courses of cefixime at a dose 400 mg 1 time a day and amoxicillin/clavulanate at a dose of 625 mg 3 times a day are high-effective treatment regimens for asymptomatic bacteriuria in pregnant women in Russia. The use of amoxicillin/clavulanate is significantly more often accompanied by the development of adverse reactions compared with cefixime.

    The aim of this prospective single-blind randomized controlled study was to evaluate the therapeutic efficacy of high dose intravenous vitamin C (HDVC) added to systemic steroid in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). Between August 2010 and August 2011, 72 ISSNHL patients who participated in this study were randomly allocated to two groups: 36 to a control group, members of which were given systemic steroid treatment for 15 days, and 36 to a HDVC group, members of which were given HDVC (200 mg/kg/day) for 10 days in addition to steroid therapy followed by oral vitamin C (2,000 mg) for 30 days after discharge. Finally, we analyzed each group: 35 as a control group and 32 as a HDVC group. Auditory evaluations were performed by pure tone audiometry (PTA) before and ~1 month after treatment using Siegel's criteria. HDVC group showed significantly greater complete and partial recovery improvement (p = 0.035). In addition, the complete recovery rate in the HDVC group was more than twice that of the control group (p = 0.031). In the HDVC group, PTA improved from 67.6 ± 19.8 dB HL before treatment to 37.1 ± 28.8 dB HL at 1 month after treatment, whereas in the control group, PTA improved from 70.3 ± 12.4 to 47.6 ± 25.2 dB HL, which represented a significant intergroup difference (p = 0.030). In conclusion, HDVC may enhance hearing recovery in ISSNHL patients, which suggests that HDVC reduces levels of reactive oxygen metabolites produced by inner ear ischemia or inflammation, and that HDVC could be considered for the treatment of ISSNHL.

Aim: To compare the effects of intranasal and transdermal 17β-estradiol combined with vaginal progesterone on vasomotor symptoms and vaginal cytology. Settings and Design: A 12-week, prospective, randomized comparative study was conducted between July 2005 and September 2006. Materials and Methods: Eighty postmenopausal women aged between 42-57 years, who had scores of ≥1.7 on the menopause rating scale-I (MRS-I items "1-6", were randomly assigned to receive intranasal (300 µg/day, n =40 or transdermal (50 µg/day, n =40 17β-estradiol continuously. All patients also received a vaginal progesterone gel twice weekly. Vasomotor symptoms were evaluated at weeks 0, 4, 8 and 12. Vaginal maturation index (VMI was evaluated at weeks 0 and 12 of the study. Statistical Analyses: The Mann-Whitney U and the Wilcoxon tests were used. P < 0.05 was regarded as significant. Results: Thirty-two women in the intranasal and 29 women in the transdermal group completed the study. The total score of the MRS, the sum-scores of Factor 1 "HOT FLUSHES" and Factor 2 "PSYCHE" significantly decreased in both groups at week 4. Factor 3 "ATROPHY" scores significantly decreased only in the transdermal group at week 12. The VMI showed no changes within and between the two groups at the end of the study. Conclusion: Intranasal and transdermal 17β-estradiol combined with vaginal progesterone gel as a continuous HRT caused a similar decrease in vasomotor symptoms but did not have any significant effect on VMI after 12 weeks of treatment in this study population.

    Full Text Available Fabrizio Cantini, Laura Niccoli, Emanuele Cassarà, Olga Kaloudi, Carlotta NanniniDivision of Rheumatology, Misericordia e Dolce Hospital, Prato, ItalyBackground: The aim of this study was to evaluate the proportion of patients with ankylosing spondylitis maintaining clinical remission after reduction of their subcutaneous etanercept dose to 50 mg every other week compared with that in patients receiving etanercept 50 mg weekly.Methods: In the first phase of this randomized, prospective, follow-up study, all biologic-naïve patients identified between January 2005 and December 2009 as satisfying the modified New York clinical criteria for ankylosing spondylitis treated with etanercept 50 mg weekly were evaluated for disease remission in January 2010. In the second phase, patients meeting the criteria for remission were randomized to receive subcutaneous etanercept as either 50 mg weekly or 50 mg every other week. The randomization allocation was 1:1. Remission was defined as Bath Ankylosing Spondylitis Disease Activity Index < 4, no extra-axial manifestations of peripheral arthritis, dactylitis, tenosynovitis, or iridocyclitis, and normal acute-phase reactants. The patients were assessed at baseline, at weeks 4 and 12, and every 12 weeks thereafter. The last visit constituted the end of the follow-up.Results: During the first phase, 78 patients with ankylosing spondylitis (57 males and 21 females, median age 38 years, median disease duration 12 years were recruited. In January 2010, after a mean follow-up of 25 ± 11 months, 43 (55.1% patients achieving clinical remission were randomized to one of the two treatment arms. Twenty-two patients received etanercept 50 mg every other week (group 1 and 21 received etanercept 50 mg weekly (group 2. At the end of follow-up, 19 of 22 (86.3% subjects in group 1 and 19 of 21 (90.4% in group 2 were still in remission, with no significant difference between the two groups.

    Full Text Available Background: Acute radiation dermatitis is a very common side effect of radiation therapy for many cancers, including breast cancer. Despite the high prevalence of acute radiation dermatitis as well as wet desquamation, only a few trials studying the prophylaxis of this complication using topical treatment have been conducted. In spite of these studies, some controversy still exists about regarding treatments for acute radiation dermatitis, as does some concern about their long-term complications. For this reason, we conducted a clinical trial for a new treatment with the same effectiveness as corticosteroids, but fewer complications. Methods: This trial included 60 patients with pathologic diagnoses of breast cancer for whom radiotherapy had been planned. Patients were 30-73 years old. Patients with radical mastectomy received 5000 cGy over five weeks, and those with conservative surgery received 6000 cGy over six weeks divided in 200 cGy fractions. Patients were divided randomly into two groups: one group received a moderately-potent glucocorticoid steroid, 0.1% betamethasone ointment (30, and the other received the new treatment, 0.1% calendula ointment (30. All patients applied their respective drugs twice daily within the tangential field from the first day of radiation treatment until one month after treatment was completed. Starting one week after radiation therapy commenced, patients were monitored weekly for symptoms of dermatitis and the degree of severity as well as possible adverse drug effects, in addition to such monitoring on the days of their appointments. Four weeks after termination of therapy, patients were again examined, at which time they completed a questionnaire about dermatologic complications. Results: The mean time to develop dermatitis was 3.7 weeks for the betamethasone group and 3.87 weeks for the calendula group. Maximal dermatitis intensity during treatment in the betamethasone group was: 0, 6.7%; I, 73.3%; II, 16

    Single procedure success rates of pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (PAF) are still unsatisfactory. In patients with persistent atrial fibrillation (AF), ablation of complex fractionated atrial electrograms (CFAEs) after PVI results in improved outcomes. We aimed to investigate if PAF-patients with intraprocedurally sustained AF after PVI might benefit from additional CFAE ablation. A total of 1134 consecutive patients underwent a first catheter ablation procedure of PAF between June 2008 and December 2012. In most patients, AF was either not inducible or terminated during PVI. In 68 patients (6%), AF sustained after successful PVI. These patients were randomized to either cardioversion (PVI-alone group; n = 33) or additional CFAE ablation (PVI+CFAE group; n = 35) and followed up every 1-3 months and serial Holter recordings were also obtained. The primary end point was the recurrence of AF/atrial tachycardia (AT) after a blanking period of 3 months. Procedure duration (127 ± 6 minutes vs 174 ± 10 minutes), radiofrequency application time (44 ± 3 minutes vs 74 ± 5 minutes), and fluoroscopy time (26 ± 2 minutes vs 41 ± 3 minutes) were longer in the PVI+CFAE group (all P PVI+CFAE group, ablation terminated AF. There was no significant group difference with respect to freedom from AF/AT (22 of 33 [67%] vs 22 of 35 [63%]; P = .66). Subsequently, 10 of 11 patients in the PVI-alone group (91%) and 11 of 13 patients in PVI+CFAE group (85%) underwent repeat ablation (P = 1.00). Overall, 29 of 33 [88%] vs 30 of 35 [86%] patients (P = 1.00) were free from AF/AT after 1.4 ± 0.1 vs 1.4 ± 0.2 (P = .87) procedures. Patients with sustained AF after PVI in a PAF cohort are rare. Regarding AF/AT recurrence, these patients did not benefit from further CFAE ablation compared to PVI alone, but are exposed to longer procedure duration, fluoroscopy time, and radiofrequency application time.

  20. Discrete least squares polynomial approximation with random evaluations - application to PDEs with Random parameters

    Nobile, Fabio

    2015-01-07

    We consider a general problem F(u, y) = 0 where u is the unknown solution, possibly Hilbert space valued, and y a set of uncertain parameters. We specifically address the situation in which the parameterto-solution map u(y) is smooth, however y could be very high (or even infinite) dimensional. In particular, we are interested in cases in which F is a differential operator, u a Hilbert space valued function and y a distributed, space and/or time varying, random field. We aim at reconstructing the parameter-to-solution map u(y) from random noise-free or noisy observations in random points by discrete least squares on polynomial spaces. The noise-free case is relevant whenever the technique is used to construct metamodels, based on polynomial expansions, for the output of computer experiments. In the case of PDEs with random parameters, the metamodel is then used to approximate statistics of the output quantity. We discuss the stability of discrete least squares on random points show convergence estimates both in expectation and probability. We also present possible strategies to select, either a-priori or by adaptive algorithms, sequences of approximating polynomial spaces that allow to reduce, and in some cases break, the curse of dimensionality

    To reduce unnecessary biopsies (Bx) in an opportunistic screening programme of prostate cancer. We perform a prospective evaluation of PCA3 as a second line biomarker in an opportunistic screening for prostate cancer (PCa). From September-2010 until September-2012, 2,366 men, aged 40-74 years and with >10 years life expectancy, were initially screened with PSA/digital rectal examination (DRE). Men with previous Bx or with recent urine infections were excluded. Men with abnormal DRE and/or PSA >3 ng/ml were submitted for PCA3. All men with PCA3 ≥ 35 underwent an initial biopsy (IBx) -12cores-. Men with PCA3 .5 ng/ml at 4-6 months or PSAv > .75 ng/ml/year. With median follow-up (FU) of 10.1 months, PCA3 was performed in 321/2366 men (13.57%), 289 at first visit and 32 during FU. All 110 PCA3+ men (34.3%) were biopsied and PCa was identified in 43 men in IBx (39.1%). In the randomized arm, 110 were observed and 101 underwent biopsy, finding 12 PCa (11.9%), showing a statistically significant reduction of PCa detection rate in this cohort (P<.001). Global PCa detection rates were 40.9% and 9.5% for the PCA3+ and PCA3- branches, respectively (P<.001). Area under the curve for PSA and PCA3 were .601 and .74, respectively. This is an ongoing prospective study limited by its short follow-up period and still limited enrolment. PCA3 as a second line biomarker within an opportunistic dual screening protocol, can potentially avoid 65.7% and 50.1% biopsies at first round and at median FU of 10.1 months, respectively, just missing around 3.2% of high grade PCa.

    To compare the quality of vision with aspheric and spherical intraocular lenses (IOLs) in pseudophakic patients. This prospective, comparative, randomized study included 250 eyes of 125 patients with bilateral cataracts. Patients were randomly assigned to receive either IOLs with a spherical biconvex optic (Acrysof SN6OAT [Alcon] or Sensar AR40e [Advanced Medical Optics, AMO]) or IOLs with an aspheric optic (Acrysof IQ SN6OWF [Alcon], Tecnis Z9000 [AMO], or Sofport L161AO [Bausch & Lomb]). Ophthalmologic examination including best spectacle-corrected visual acuity, pupil size, ocular dominance investigation, contrast sensitivity under mesopic and photopic conditions, and wavefront analysis was performed 2 months postoperatively. Aspheric IOLs showed better contrast sensitivity compared to spherical IOLs at spatial frequencies of 6, 12, and 18 cycles per degree (cpd) under photopic conditions and at all spatial frequencies under mesopic conditions. There was no significant difference among the three aspheric IOLs at all spatial frequencies under either photopic or mesopic conditions. Mean total spherical aberration was statistically lower in dominant eyes with aspheric IOLs (0.05 +/- 0.06, 0.11 +/- 0.1, and 0.19 +/- 0.08 pm for the Tecnis Z9000, Acrysof IQ SN6OWF, and Sofport L161AO, respectively) compared with eyes with spherical IOLs (0.62 +/- 0.24 and 0.46 +/- 0.19 microm for the Acrysof SN6OAT and Sensar AR40e, respectively) for a 5-mm pupil diameter. The aspheric IOLs had less wavefront aberrations and performed better under both photopic and mesopic contrast sensitivity compared to the spherical IOLs. These findings confirm it is possible to improve the optical performance of IOLs by modifying the surfaces.

    Shivering, a common intraoperative problem under spinal anesthesia increases the oxygen consumption considerably and is uncomfortable and distressing to the patient, anesthesiologist as well as surgeon. The present study was designed to explore the effectiveness of tramadol, clonidine and dexmedetomidine in the treatment of post spinal anesthesia shivering and to look for their adverse effects. This prospective, randomized, double blinded control study was done on 90 patients who developed shivering under spinal anesthesia. They were randomly allocated into three groups with Group T receiving tramadol 1mg.kg(-1), Group C getting clonidine 1mcg.kg(-1) and Group D patients receiving dexmedetomidine 0.5mcg.kg(-1). The time taken to control shivering, recurrence rate, hemodynamic variables, sedation score and adverse effects were observed. Dexmedetomidine was faster in the control of shivering in 5.7±0.79minutes (min) whereas tramadol took 6.76±0.93min and clonidine was slower with 9.43±0.93min. The recurrence rate was much lower in the dexmedetomidine group with 3.3% than for clonidine (10%) and tramadol (23.3%) group. The sedation achieved with dexmedetomidine was better than clonidine and tramadol. The tramadol group had more cases of vomiting (four) and dexmedetomidine group had six cases of hypotension and two cases of bradycardia. Two of the clonidine patients encountered bradycardia and hypotension. Dexmedetomidine is better than tramadol and clonidine in the control of shivering because of its faster onset and less recurrence rate. Though complications are encountered in the dexmedetomidine group, they are treatable. Copyright © 2016 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

    Full Text Available ABSTRACT Objectives: To compare the response to tiocolchicine and verapamil injection in the plaque of patients with Peyronie's disease. Materials and Methods: Prospective, single-blind, randomized study, selecting patients who have presented Peyronie's disease for less than 18 months. Thiocolchicine 4mg or verapamil 5mg were given in 7 injections (once a week. Patients who had received any treatment for Peyronie's disease in the past three months were excluded. The parameters used were the International Index of Erectile Function (IIEF-5 score, analysis of the curvature on pharmaco-induced erections and size of the plaque by ultrasonography. Results: Twenty-five patients were randomized, 13 received thiocolchicine and 12 were treated with verapamil. Both groups were statistically similar. The mean curvature was 46.7° and 36.2° before and after thiocolchicine, respectively (p=0.019 and 50.4° and 42.08° before and after verapamil, respectively (p=0.012. The curvature improved in 69% of patients treated with thiocolchicine and in 66% of those who received verapamil. Regarding sexual function, there was an increase in the IIEF-5 from 16.69 to 20.85 (p=0.23 in the thiocolchicine group. In the verapamil group the IIEF-5 score dropped from 17.50 to 16.25 (p=0.58. In the thiocolchicine group, the plaque was reduced in 61% of patients. In the verapamil group, 8% presented decreased plaque size. No adverse event was associated to thiocolchicine. Conclusion: The use of thiocolchicine in Peyronie's disease demonstrated improvement on penile curvature and reduction in plaque size. Thiocolchicine presented similar results to verapamil in curvature assessment. No significant side effects were observed with the use of tiocolchicine.

    During total knee arthroplasty (TKA), surgical exposure requires mobilization technique of the patella. With this trial, we intended to investigate the effect of patella eversion on clinical outcome measures in simultaneous bilateral TKA. We prospectively enrolled 44 patients (88 knees) from April 2008 to June 20l4.One knee was operated with patella eversion (group A) and the other with patella lateral retraction (group B) randomly. Follow-up results, including the operation time, complications, and the time of achieving straight leg raise (SLR) and 90° knee flexion, were recorded. The data of range of motion (ROM) and Visual Analogue Scale score were collected separately at 7 days, 3 months, 6 months, and 1 year postoperatively. The time of achieving SLR was 2.7 ± 0.8 days in group A and 2.1 ± 0.7 DAYS in group B, which were significantly different (P = .032). Significant difference was found on active and passive ROM during the follow-up times between groups A and B, except the passive ROM at 6 months postoperatively. No significant difference was found on operation time, complications, patella baja or tilt, time of achieving 90°knee flexion, and Visual Analogue Scale score during the follow-up times. Patellar eversion was adverse to the early knee function recovery after TKA; it would delay the time of achieving SLR and decrease the passive and active ROM. In addition, more carefully and scientifically designed randomized controlled trials are still required to further prove the claim. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Aims and Objectives: To assess the effect of Comprehensive Yogic Breathing Program on glycemic control, quality of life, and cardiac autonomic functions in diabetes. Material and Methods: This is a prospective randomized controlled intervention trial. Cardiac autonomic functions were assessed in 120 diabetics. Patients were randomized into two groups, one group receiving standard therapy for diabetes (n = 56 and the other group receiving standard therapy for diabetes and comprehensive yogic breathing program (n = 64. Standard therapy included advice on diet, walk, and oral antidiabetic drugs. Comprehensive yogic breathing program was an interactive session in which Sudarshan kriya yoga, a rhythmic cyclical breathing, preceded by Pranayam was taught under guidance of a certified teacher. Change in fasting, post prandial blood sugars, glycated hemoglobin, and quality of life were assessed. Cardiac autonomic function tests were done before and six months after intervention. Results: There was significant improvement in psychological (P = 0.006 and social domains (P = 0.04 and total quality of life (P = 0.02 in the group practicing comprehensive yogic breathing program as compared to the group following standard therapy alone. In the group following breathing program, the improvement in sympathetic cardiac autonomic functions was statistically significant (P = 0.01, while the change in the standard group was not significant (P = 0.17. When both parasympathetic and sympathetic cardiac autonomic functions were considered, there was a trend toward improvement in patients following comprehensive yogic breathing program (P = 0.07. In the standard therapy group, no change in cardiac autonomic functions was noted (P = 0.76. The parameters of glycemic control were comparable in both groups. Conclusion: There was significant improvement in quality of life and cardiac autonomic functions in the diabetes patients practicing comprehensive yogic breathing

    To investigate whether positioning the body in a lateral decubitus position will facilitate nasogastric tube insertion in unconscious patients. Inserting a nasogastric tube into unconscious patients can be challenging because these patients cannot cooperate with the operator. The piriform sinus and arytenoid cartilage are the most commonly reported impaction sites. However, we found that the first impaction site was the backward displaced tongue when inserting a nasogastric tube in unconscious patients who often exhibited glossoptosis. Performing an intubation in the lateral decubitus position could make this procedure easy. This prospective, double-blind, parallel, randomized controlled trial was conducted in Hengshui City, Hebei Province, China. 110 cases of unconscious patients were enrolled. The patients were randomly assigned to a conventional group (group C) or a lateral decubitus position group (group L). In group C, the nasogastric tube was inserted while the patients were in a supine position using the conventional technique, and in group L, the tube was inserted in a lateral decubitus position or further tilting the body to a prone decubitus position 20-30 degrees. We discussed reasonable intubation methods in unconscious patients by comparing the success rate on first insertion, the overall success rate, the intubation time and the complication rates between the two groups. Group L had a higher success rate on first insertion and overall success rate than group C (Ppassage. Nasogastric tube insertions in the lateral decubitus position are recommended in unconscious patients because of the higher success rate, reduced intubation time and lower complication rate.

    Absolute grading system of homeopathic repertories poses substantial threat to reliability; however, it may be resolved by evaluating rubrics prospectively using likelihood ratio (LR). The authors evaluated few "physical general" rubrics from Kent's repertory-"chilly," "hot," "ambithermal," "preference for hot/cold food," "desire/aversion for fish/egg/meat/sour/pungent/salt/sweet/bitter"-prospectively in West Bengal, India, for 1.5 years using the Outcome Related to Impact on Daily Living scale. Per symptom/rubric, LRs rubric with corresponding medicines was suggested to be introduced, new entries of medicines were recommended, and some seemed to maintain their ascribed importance. The authors refrained from converting LRs into typefaces prematurely; still they propose introducing LR to repertories for a structural update, changing its use, and enabling homeopaths to make more reliable predictions.

    To evaluate the change in respiratory function and functional capacity according to the type of preoperative fasting. Randomized prospective clinical trial, with 92 female patients undergoing cholecystectomy by laparotomy with conventional or 2 hours shortened fasting. The variables measured were the peak expiratory flow, forced expiratory volume in the first second, forced vital capacity, dominant handgrip strength, and non-dominant handgrip strength. Evaluations were performed 2 hours before induction of anesthesia and 24 hours after the operation. The two groups were similar in preoperative evaluations regarding demographic and clinical characteristics, as well as for all variables. However, postoperatively the group with shortened fasting had higher values than the group with conventional fasting for lung function tests peak expiratory flow (128.7±62.5 versus 115.7±59.9; p=0.040), forced expiratory volume in the first second (1.5±0.6 versus 1.2±0.5; p=0.040), forced vital capacity (2.3±1.1 versus 1.8±0.9; p=0.021), and for muscle function tests dominant handgrip strength (24.9±6.8 versus 18.4±7.7; p=0.001) and non-dominant handgrip strength (22.9±6.3 versus 17.0±7.8; p=0.0002). In the intragroup evaluation, there was a decrease in preoperative compared with postoperative values, except for dominant handgrip strength (25.2±6.7 versus 24.9±6.8; p=0.692), in the shortened fasting group. Abbreviation of preoperative fasting time with ingestion of maltodextrin solution is beneficial to pulmonary function and preserves dominant handgrip strength.

    Full Text Available Abstract Background We previously demonstrated improved sweating after enzyme replacement therapy (ERT in Fabry disease using the thermo-regularity sweat and quantitative sudomotor axon reflex tests. Skin-impedance, a measure skin-moisture (sweating, has been used in the clinical evaluation of burns and pressure ulcers using the portable dynamic dermal impedance monitor (DDIM system. Methods We compared skin impedance measurements in hemizygous patients with Fabry disease (22 post 3-years of bi-weekly ERT and 5 ERT naive and 22 healthy controls. Force compensated skin-moisture values were used for statistical analysis. Outcome measures included 1 moisture reading of the 100th repetitive reading, 2 rate of change, 3 average of 60–110th reading and 4 overall average of all readings. Results All outcome measures showed a significant difference in skin-moisture between Fabry patients and control subjects (p Conclusion The instrument portability, ease of its use, a relatively short time required for the assessment, and the fact that DDIM system was able to detect the difference in skin-moisture renders the instrument a useful clinical tool.

    Full Text Available To determine whether the complementary approach of visceral manipulative osteopathic treatment accelerates complete meconium excretion and improves feeding tolerance in very low birth weight infants.This study was a prospective, randomized, controlled trial in premature infants with a birth weight <1500 g and a gestational age <32 weeks who received a visceral osteopathic treatment 3 times during their first week of life or no treatment.Passage of the last meconium occurred after a median of 7.5 days (95% confidence interval: 6-9 days, n = 21 in the intervention group and after 6 days (95% confidence interval: 5-9 days, n = 20, in the control group (p = 0.11. However, osteopathic treatment was associated with a 8 day longer time to full enteral feedings (p = 0.02, and a 34 day longer hospital stay (Median = 66 vs. 100 days i.e.; p=0.14. Osteopathic treatment was tolerated well and no adverse events were observed.Visceral osteopathic treatment of the abdomen did not accelerate meconium excretion in VLBW (very low birth weight-infants. However infants in the osteopathic group had a longer time to full enteral feedings and a longer hospital stay, which could represent adverse effects. Based on our trial results, we cannot recommend visceral osteopathic techniques in VLBW-infants.Clinical trials.gov: NCT02140710.

    Acute diarrhea remains a public health concern in armed forces deployed in tropical areas where access to water and soap is limited. This study aims to assess the effectiveness of alcohol-based hand rubs (ABHR) on incidence of diarrhea in poor hygiene conditions. A prospective randomized trial was conducted between November 2014 and January 2015 among French military troops deployed in Africa to compare a group of soldiers receiving usual hand hygiene recommendations (control group), to a group of soldiers who received ABHR in addition to usual hand hygiene recommendations (intervention group). Data on diarrhea and hygiene behaviors were collected using self-questionnaires. The incidence rate of diarrhea episodes in groups was compared. Participation rate was 59% (236/400). The proportion of individuals who used ABHR was 97% in the intervention group and 62% in the control group. The overall incidence rate of diarrheal episodes was observed to be in the region of 60 per 100 persons-month without any significant difference between groups after adjustment on confounding factors (p = 0.93). Handwashing with soap was used on average 4 times a day in the control group and twice a day in the intervention group (p = 0.93). It was the only significant protective factor for diarrhea (p soap and good quality water should be a priority on the field. Copyright © 2016. Published by Elsevier Ltd.

    Full Text Available A prospective randomized study was conducted in order to compare augmentation technique versus nonaugmentation technique, followed by early functional postoperative treatment, for operative repair of Achilles tendon ruptures. Twenty-four consecutive patients were assigned to two groups. Group I included 12 patients treated with Lindholm augmentation technique, whereas group II included 12 patients treated with modified Kessler end-to-end repair. Thereafter, these patients had postoperative management with a below-knee-cast for three weeks. The physioteraphy was initiated immediately after the cast was removed. Full weight bearing was allowed after five weeks postoperatively in the both groups. Two patients had reruptures in group II, whereas group I had prolonged operative time significantly. The patients with reruptures underwent reoperations and at the most final follow-up, it was observed that they could not resume to sporting activities. The other objective and subjective results were similar between two groups. Because of quite high rerupture rate in the group of patients treated with nonaugmentation technique, we favor functional postoperative treatment with early ankle movement in the patients treated with augmentation technique for the management of acute rupture of the Achilles tendon

    Medical procedures in outpatient settings have limited options of managing pain and anxiety pharmacologically. We therefore assessed whether this can be achieved by adjunct self-hypnotic relaxation in a common and particularly anxiety provoking procedure. Two hundred and thirty-six women referred for large core needle breast biopsy to an urban tertiary university-affiliated medical center were prospectively randomized to receive standard care (n=76), structured empathic attention (n=82), or self-hypnotic relaxation (n=78) during their procedures. Patients' self-ratings at 1 min-intervals of pain and anxiety on 0-10 verbal analog scales with 0=no pain/anxiety at all, 10=worst pain/anxiety possible, were compared in an ordinal logistic regression model. Women's anxiety increased significantly in the standard group (logit slope=0.18, pempathy group (slope=-0.04, p=0.45), and decreased significantly in the hypnosis group (slope=-0.27, pempathy=0.37, hypnosis=0.34; all pempathy than standard care (p=0.024 and p=0.018, respectively). Room time and cost were not significantly different in an univariate ANOVA despite hypnosis and empathy requiring an additional professional: 46 min/161 dollars for standard care, 43 min/163 dollars for empathy, and 39 min/152 dollars for hypnosis. We conclude that, while both structured empathy and hypnosis decrease procedural pain and anxiety, hypnosis provides more powerful anxiety relief without undue cost and thus appears attractive for outpatient pain management.

    The authors assessed the potential benefit of postoperative radiation therapy for rectal cancer in a two-arm, prospective multicenter trial. One hundred seventy-two patients who had undergone surgical resection for rectal adenocarcinoma were randomly assigned to either treatment consisting of external irradiation to a dose of 5000 cGy in 5 weeks or a control group (no adjuvant therapy). It was assumed that the number of cells remaining after radical surgery would be low and that the dose of 5000 cGy would be adequate in eradicating the majority of those cells. The number of local recurrences was lower in the treated group of patients, but the difference was not statistically significant. It was assumed that if a significant reduction in the number of local recurrences could be obtained, improved (disease-free) survival would result. No influence on disease-free or overall survival could be detected. These results were in agreement with those reported in Europe and the US, and it was concluded that postoperative radiation therapy alone cannot be justified as a routine procedure in the primary management of resectable rectal cancer.

    AIM: To compare ecabet sodium and cimetidine in relieving symptoms of functional dyspepsia.METHODS: We performed a multi-center, prospective,randomized, double-blinded controlled trial to compare the clinical efficacy of ecabet sodium and cimetidine in patients with functional dyspepsia. Two-hundred and seventy-two patients with dyspeptic symptoms fulfilling the Rome-Ⅱ criteria were enrolled from 7 centers. In the study group (115 patients), 1.5 g ecabet sodium was given twice a day. In the control group (121 patients),400 mg cimetidine was given twice a day. Symptoms and parameters of quality of life were analyzed at baseline, 3,14, and 28 d after initiating the treatment.RESULTS: Two-hundred and thirty-six patients completed the clinical trial. After 4 wk of treatment,the rates of improvement in patients with dyspeptic symptoms were not different between two groups (77.4% in the ecabet group and 79.3% in the cimetidine group, respectively, P > 0.05). Likewise, the rates of symptomatic improvement were not different at 3 d and 14 d. The parameters of quality of life did not change significantly during the study period in both groups.There was no clinically significant adverse event in both groups.CONCLUSION: In patients with functional dyspepsia,ecabet sodium has similar clinical efficacy with cimetidine.

    The unique challenges inherent to microneurosurgery demand that we stay on the forefront of new surgical technologies. Many believe the next major technological advance in neurosurgery will be the widespread application of image-guided robotics in the operating room. We evaluated a novel technology for image-guided robotic auto-navigation of the operating microscope in a prospectively enrolled cohort of patients. Twenty patients were prospectively enrolled for analysis. Data were collected on the extent of resection, operative time, estimated blood loss, time taken to set up the new software, and complications encountered. Software accuracy, reliability, and usefulness in the case were subjectively evaluated. The most commonly  treated pathologies were cavernous malformation (n = 5), arteriovenous malformation (n = 4), and meningioma (n = 4). The time to set up the new software interface before the start of the operation was microscope has a great potential to advance the field of neurosurgery. This study is the first prospective evaluation of such a technology in a patient cohort. The results suggest that the newest robotic auto-positioning technology has the potential to improve the neurosurgeon's efficiency and efficacy, thereby positively impacting patient safety and surgical outcomes, especially in cases involving deep-seated lesions.

    Background Hypertension is often complicated by increased arterial stiffness and is an independent predictor of adverse cardiovascular (CV) outcome. Beta blockers and angiotensin receptor blockers (ARBs) are commonly used antihypertensive agents. The effect of beta blockers and ARBs on arterial stiffness has not been compared adequately. The aim of the present study is to compare the effect of telmisartan with metoprolol on arterial stiffness in hypertensive patients in prospective open label randomized parallel group intervention study. Methods 100 patients of hypertension, not on any antihypertensive agents, were enrolled after obtaining informed consent. Baseline recording of data related to demographics, CV risk factors, anthropometry and BP were made. Arterial stiffness was measured noninvasively by recording pulse wave velocity (PWV) using periscope (Genesis medical system). Left ventricular (LV) mass was measured using 2D guided M-mode echocardiography. Blood sugar, renal function, lipids and uric acid estimations were done in fasting state. Patients were randomized to receive metoprolol and telmisartan using stratified randomization technique. Dose of the study drugs were titrated to achieve target BP of <140/90 mmHg. Data related to PWV, BP, anthropometry and blood biochemistry was repeated after 6 months of treatment with study drugs. Results Telmisartan resulted in significantly greater reduction in arterial stiffness index (ASI) in left and right lower limb arterial bed (39.9 ± 11.7 vs. 46.8 ± 17.0 m/s, p < 0.02) and (36.4 ± 9.6 vs. 44.86 ± 15.1 m/s, p < 0.002) respectively and systolic blood pressure (SBP) (−4.9 mmHg with 95% C.I. of −8.0–1.7 mmHg, p < 0.003) compared to metoprolol. Reduction in diastolic blood pressure (DBP) in telmisartan and metoprolol groups was not different statistically (−1.0 mmHg with 95% C.I. of −3.3–1.2 mmHg, p < 0.3). The change in LV mass was not significantly different between the

    The effects on children of parental presence in the postanesthesia care unit (PACU) have not been extensively studied. The few published studies are retrospective, nonrandomized, or lack adequate controls. They suggest that parental presence in the PACU decreases crying and negative behavior change postoperatively. We performed this prospective, randomized, controlled study to determine whether the presence of a parent affected crying behaviors in the PACU and behavior change 2 weeks postoperatively. Randomly selected patients, aged 2.0 to 8 years 11 months, ASA physical status I or II, and scheduled for elective outpatient surgery with an anticipated PACU stay of >10 minutes were randomly assigned to the parent present group (n = 150) or parent absent group (n = 150) in the PACU. All parents underwent the same preparation program. Reunification occurred once children's eyes had opened for the parent present group. In the PACU, crying was scored each minute after eye opening using a 5-point scale. Negative behavior change 2 weeks after discharge was determined using the Post Hospitalization Behavior Questionnaire. Because the anesthesia technique to be used was not determined a priori, data on the technique used were collected to ensure that groups were similar. Multiple and logistic regression techniques were used to determine predictors of crying in the PACU and behavior change 2 weeks postoperatively. Parental presence in the PACU made no difference in crying in the PACU. Negative behavior change 2 weeks postoperatively occurred more frequently in the parent absent group than the parent present group (45.8% vs 29.3%; P = 0.007). Multiple regression identified the following significant factors as predictive of larger proportion of time spent crying in the PACU (R(2) = 0.256, F[5, 273] = 15.66, P < 0.001): age <5 years (P < 0.001) and higher Children's Hospital of Eastern Ontario Pain Scale score at 15 minutes after arrival in day surgery (P < 0.001).

    The aims of this service evaluation were to explore the effectiveness of a psychotherapeutic treatment for patients with epilepsy based on the acceptance and commitment therapy (ACT) approach and to assess whether this treatment is likely to be cost-effective. We conducted an uncontrolled prospective study of consecutive patients with refractory epilepsy referred for outpatient psychological treatment to a single psychotherapist because of emotional difficulties related to their seizure disorder. Participants were referred by consultant neurologists, neuropsychologists, or epilepsy nurses, completed a set of validated self-report questionnaires (Short Form - 12 version 2, Generalized Anxiety Disorder - 7, Neurological Disorders Depression Inventory for Epilepsy, Work and Social Adjustment Scale, and Rosenberg Self-Esteem Scale), and reported their seizure frequency at referral, the end of therapy, and six months posttherapy. Patients received a maximum of 20 sessions of one-to-one psychological treatment supported by a workbook. Cost-effectiveness was estimated based on the calculation of quality-adjusted life year (QALY) gains associated with the intervention. Sixty patients completed the prepsychotherapy and postpsychotherapy questionnaires, among whom 41 also provided six-month follow-up data. Patients received six to 20 sessions of psychotherapy (mean=11.5, S.D.=9.6). Psychotherapy was associated with significant medium to large positive effects on depression, anxiety, quality of life, self-esteem, and work and social adjustment (pstherapy. The mean cost of the psychotherapy was £445.6, and, assuming that benefits were maintained for at least six months after the end of therapy, the cost per QALY was estimated to be £11,140 (€14,119, $18,016; the cost per QALY would be half this amount if the benefits lasted one year). The findings of this pilot study indicate that the described psychotherapeutic intervention may be a cost-effective treatment for patients

  7. Evaluating Random Forests for Survival Analysis Using Prediction Error Curves

    Directory of Open Access Journals (Sweden)

    Ulla B. Mogensen

    2012-09-01

    Full Text Available Prediction error curves are increasingly used to assess and compare predictions in survival analysis. This article surveys the R package pec which provides a set of functions for efficient computation of prediction error curves. The software implements inverse probability of censoring weights to deal with right censored data and several variants of cross-validation to deal with the apparent error problem. In principle, all kinds of prediction models can be assessed, and the package readily supports most traditional regression modeling strategies, like Cox regression or additive hazard regression, as well as state of the art machine learning methods such as random forests, a nonparametric method which provides promising alternatives to traditional strategies in low and high-dimensional settings. We show how the functionality of pec can be extended to yet unsupported prediction models. As an example, we implement support for random forest prediction models based on the R packages randomSurvivalForest and party. Using data of the Copenhagen Stroke Study we use pec to compare random forests to a Cox regression model derived from stepwise variable selection.

    This paper presents the rationale and methods for a randomized controlled evaluation of web-based training in motivational interviewing, goal setting, and behavioral task assignment. Web-based training may be a practical and cost-effective way to address the need for large-scale mental health training in evidence-based practice; however, there is a dearth of well-controlled outcome studies of these approaches. For the current trial, 168 mental health providers treating post-traumatic stress disorder (PTSD) were assigned to web-based training plus supervision, web-based training, or training-as-usual (control). A novel standardized patient (SP) assessment was developed and implemented for objective measurement of changes in clinical skills, while on-line self-report measures were used for assessing changes in knowledge, perceived self-efficacy, and practice related to cognitive behavioral therapy (CBT) techniques. Eligible participants were all actively involved in mental health treatment of veterans with PTSD. Study methodology illustrates ways of developing training content, recruiting participants, and assessing knowledge, perceived self-efficacy, and competency-based outcomes, and demonstrates the feasibility of conducting prospective studies of training efficacy or effectiveness in large healthcare systems.

    2004-04-21

    We sought to evaluate the influence of pretreatment systolic blood pressure (SBP) on the efficacy and safety of carvedilol in patients with chronic heart failure (CHF). Although beta-blockers reduce the risk of death in CHF, there is little reported experience with these drugs in patients with a low pretreatment SBP, who may respond poorly to beta-blockade. We studied 2,289 patients with severe CHF who participated in the Carvedilol Prospective Randomized Cumulative Survival (COPERNICUS) trial. Compared with placebo, carvedilol improved the clinical status and reduced the risk of death and the combined risk of death or hospitalization for any reason, for a cardiovascular reason, or for worsening heart failure (p 0.10). However, because patients with the lowest SBP were at highest risk of an event, they experienced the greatest absolute benefit from treatment with carvedilol. The lower the pretreatment SBP, the more likely that patients would report an adverse event, be intolerant of high doses of the study drug, or require permanent withdrawal of treatment (p < 0.001 for all). However, these risks were primarily related to the severity of the underlying illness and not to treatment with carvedilol. The current study provides little support for concerns about using beta-blockers (particularly those with vasodilatory actions) in patients with severe CHF who have a low SBP. Pretreatment blood pressure can identify patients who have the greatest need for risk reduction with carvedilol.

    To evaluate the effect of listening to music on pain, anxiety, or stress during a urodynamic study (UDS). A total of 74 female and 74 male patients who underwent UDS between March 2013 and October 2013 were prospectively randomized. The patients were divided into 2 groups according to gender (female, n = 74 vs male, n = 74) and into 2 subgroups according to whether they listened to music or not. Music group subjects played their preferred music during UDS. Before and after UDS, all subjects completed the State-Trait Anxiety Inventory (STAI) form and their degree of pain, anxiety, and satisfaction during examination were assessed by the visual analog scale (VAS, 0-10). Basic vital signs were also checked before and after the procedure. In the analysis of anxiety, pain, and stress scores, the mean shame, discomfort, and satisfaction scores (VAS) were significantly higher in female patients, whereas the mean score of willingness to retry the procedure was higher in male patients whether listening to music or not (P music group and the no-music group in either gender. In our study, music during UDS did not reduce anxiety, pain, and stress in either gender. In the analysis focusing on gender difference, female patients showed statistically higher levels of pain, anxiety, and stress scores than male patients whether listening to music or not.

    The aim of this study was to evaluate the effect of dehydroepiandrosterone (DHEA) supplementation on in vitro fertilization (IVF) data and outcomes among poor-responder patients. A randomized, prospective, controlled study was conducted. All patients received the long-protocol IVF. Those in the study group received 75 mg of DHEA once a day before starting the next IVF cycle and during treatment. Thirty-three women with significantly diminished ovarian reserves were enrolled, 17 in the DHEA group and 16 in the control group. The 33 patients underwent 51 IVF cycles. The DHEA group demonstrated a non-significant improvement in estradiol levels on day of hCG (P = 0.09) and improved embryo quality during treatment (P = 0.04) between first and second cycles. Patients in the DHEA group also had a significantly higher live birth rate compared with controls (23.1% versus 4.0%; P = 0.05), respectively. Six of seven deliveries were among patients with secondary infertility (P = 0.006). Dehydroepiandrosterone supplementation can have a beneficial effect on ovarian reserves for poor-responder patients on IVF treatment. Clinicaltrials.gov: NCT01145144.

    The aim of this prospective randomized control trial was to analyse the efficacy of a new trans-septal alar base cinch suture in controlling alar width in patients undergoing maxillary intrusion and setback by comparing it with the traditional cinch suture. Statistical evaluation was carried out in 62 of 76 patients. Group I (31 patients) received the traditional alar base cinch suture, and group II (31 patients) received the alar base cinch suture with an anchoring bite taken through the nasal septum 10mm behind its anterior edge. In both groups the accurate identification of alar fibroareolar tissue was facilitated by an 18 gauge green needle passed extra orally. Alar base width was measured before and 6 months after surgery using Vernier callipers. Preoperative alar base width for group I was 29.76 mm (1.901SD) and for group II 29.79 mm (3.141SD); the postoperative values were 32.42 mm (1.858SD) and 29.94 mm (2.568SD), respectively. Mean alar base widening was 2.661 mm (0.800SD) in group I and 0.145 mm (2.050) in group II. The difference in alar widening was statistically significant (palar cinch suture offers better control of alar base architecture in maxillary intrusion and setback.

    Placebo controlled double-blinded, prospectively randomized clinical trial with 17 patients (11 verum, 5 placebo) for evaluation of cellulite treatment with Acoustic Wave Therapy, (AWT(®)) was performed. The patients were treated once a week for 7 weeks, a total of 8 treatments with the D-ACTOR(®) 200 by Storz Medical AG. Data were collected at baseline, before 8th treatment, at 1 month (follow-up 1) and at 3 months (follow-up 2) after the last treatment with a patients' questionnaire, weight control, measurement of circumference and standardized photography. Treatment progress was further documented using a specially designed 3D imaging system (SkinSCAN(3D), 3D-Shape GmbH) providing an objective measure of cellulite (primary efficacy criteria). Patient's questionnaire in the verum group revealed an improvement in number and depth of dimples, skin firmness and texture, in shape and in reduction of circumference. The overall result (of skin waviness, Sq and Sz, surface and volume of depressions and elevations, Vvv and Vmp) at two follow-up visits indicates a more than medium sized superiority (MW = 0.6706) and is statistically significant (pWei-Lachin = 0.0106). The placebo group revealed no statistical significance. No side effects were seen. This indicates the efficacy and safety of AWT(®) for patients with cellulite.

    Full Text Available Abstract Background Multilevel spinal fusion surgery has typically been associated with significant blood loss. To limit both the need for transfusions and co-morbidities associated with blood loss, the use of anti-fibrinolytic agents has been proposed. While there is some literature comparing the effectiveness of tranexamic acid (TXA to epsilon aminocaproic acid (EACA in cardiac procedures, there is currently no literature directly comparing TXA to EACA in orthopedic surgery. Methods/Design Here we propose a prospective, randomized, double-blinded control study evaluating the effects of TXA, EACA, and placebo for treatment of adolescent idiopathic scoliosis (AIS, neuromuscular scoliosis (NMS, and adult deformity (AD via corrective spinal surgery. Efficacy will be determined by intraoperative and postoperative blood loss. Other clinical outcomes that will be compared include transfusion rates, preoperative and postoperative hemodynamic values, and length of hospital stay after the procedure. Discussion The primary goal of the study is to determine perioperative blood loss as a measure of the efficacy of TXA, EACA, and placebo. Based on current literature and the mechanism by which the medications act, we hypothesize that TXA will be more effective at reducing blood loss than EACA or placebo and result in improved patient outcomes.

    The study evaluated eradication of methicillin-resistant Staphylococcus aureus (MRSA) from pressure ulcers comparing swabs containing polyhexanide with a cellulose dressing + polyhexanide. After receiving approval from the ethics committee and informed consent, patients from the centers were recruited. Prospective randomized study. Thirty patients (n = 15/n = 15), not responding to wound disinfection after a washout period of 2 weeks, were included in the intention-to-treat analysis. This study was performed on hospital patients. Patients had pressure ulcers containing MRSA. For the control group, cleansing was performed with polyhexanide swabs (20 minutes), after which a foam dressing was applied. The study group received a polyhexanide-containing cellulose dressing. For bacterial analysis, semiquantitative swab cultures (Robert Koch Institute recommendations) were taken on days 0, 7, and 14 and during 3 consecutive days. The groups were comparable at baseline. At day 7, in the control group, 6 of 15 (40%) MRSA eradication. For the study group, there were 13 of 15 (86.67%) who showed MRSA eradication. At day 14, in the control group, there were 10 of 15 (66.67%) who had MRSA eradication, compared with the study group, where 15 of 15 (100%; P polyhexanide was shown to be successful in both groups, showing superior results for the study group.

    Hemodynamic response to airway stimuli is a common phenomenon and its management is important to reduce the systemic repercussions. The objective of this study is to compare the efficacy of intravenous magnesium sulfate versus lidocaine on this reflex hemodynamics after laryngoscopy and tracheal intubation. This single-center, prospective, double-blind, randomized study evaluated 56 patients ASA 1 or 2, aged 18-65 years, scheduled for elective surgeries under general anesthesia with intubation. The patients were allocated into two groups: Group F received 30mg·kg(-1) of magnesium sulphate and Group L, 2mg·kg(-1) of lidocaine, continuous infusion, immediately before the anesthetic induction. Blood pressure (BP), heart rate (HR), and bispectral index (BIS) were measured in both groups at six different times related to administration of the study drugs. In both groups there was an increase in HR and BP after laryngoscopy and intubation, compared to baseline. Group M showed statistically significant increase in the values of systolic and diastolic blood pressure after intubation, which was clinically unimportant. There was no difference in the BIS values between groups. Among patients receiving magnesium sulfate, three (12%) had high blood pressure versus only one among those receiving lidocaine (4%), with no statistical difference. Magnesium sulfate and lidocaine have good efficacy and safety for hemodynamic management in laryngoscopy and intubation. Copyright © 2016 Sociedade Brasileira de Anestesiologia.

    This study compared the efficacy of topical captopril with topical diltiazem in the treatment of chronic anal fissure (CAF). Fifty patients aged between 15 and 75 years with CAF were included in a prospective randomized, double-blind clinical trial. They were randomly allocated to either captopril (0.5%) cream or diltiazem (2%) cream in a dose of 2 cm of cream on the perianal skin every 12 h for 8 weeks. The intensity of pain upon defaecation was evaluated every 10 days using a visual analogue scale. Bleeding on defaecation, pruritus and the presence of perianal irritation were also recorded before and during the trial. The average pain scores were lower in the diltiazem group on the 20th and 30th days. From day 40 to the end of the trial the average pain scores of the two groups did not differ significantly. There were no significant differences in bleeding or perianal irritation between the groups, but the incidence of pruritus was considerably higher in the captopril group, and at the end of the trial 45.8% of the patients in this group still suffered from pruritus. Topical captopril and diltiazem were found to be equally effective in the management of pain, bleeding and perianal irritation due to CAF, but due to the high incidence of pruritus observed with topical captopril this medication is not recommended for the treatment of CAF.

    Wide-area transepithelial sampling (WATS) with computer-assisted 3-dimensional analysis is a sampling technique that combines abrasive brushing of the Barrett's esophagus (BE) mucosa followed by neural network analysis to highlight abnormal-appearing cells. We performed a randomized trial of referral BE patients undergoing surveillance at 16 medical centers. Subjects received either biopsy followed by WATS, or vice versa. The primary outcome was rate of detection of HGD/EAC using WATS in conjunction with biopsy compared with biopsy alone using standard histopathologic criteria. Secondary aims included evaluating neoplasia detection rates (1) based on the procedure order (WATS vs biopsy first) (2) of each procedure separately, and (3) the additional time required for WATS. One hundred sixty patients (mean age 63.4 years, 76% male; 95% white) completed the trial. The median circumferential and maximal BE extents were 1.0 (IQR: 0.0-5.0) cm and 4.0 (IQR, 2.0-8.0) cm, respectively. The diagnostic yield for biopsy alone was as follows: HGD/EAC, 7 (4.4%); low-grade dysplasia (LGD), 28 (17.5%); non-dysplastic BE (NDBE), 106 (66.25%); and no BE, 19 (11.9%). The addition of WATS to biopsy yielded an additional 23 cases of HGD/EAC (absolute increase, 14.4%; 95% CI, 7.5%-21.2%). Among these 23 patients, 11 were classified by biopsy as NDBE, and 12 as LGD/IND; 14 received biopsy and 9 WATS first (p=NS) and the majority (n=21; 91.7%) had a prior dysplasia history. WATS added average of 4.5 minutes to the procedure. Results of this multicenter, prospective, randomized trial demonstrate that the use of WATS in a referral BE population increases the detection of HGD/EAC.

    Recently, studies have reported that extracorporeal shock wave therapy (ESWT) is a safe, noninvasive, alternative treatment for spasticity. However, the effect of ESWT on spasticity cannot be determined, because most studies to date have enrolled small patient numbers and have lacked placebo-controlled groups and/or long-term follow-up. In addition, whether varying the number of ESWT sessions would affect the duration of the therapeutic effect has not been investigated in a single study. Hence, we performed a prospective, randomized, single blind, placebo-controlled study to investigate the long-term effect of radial ESWT (rESWT) in patients with poststroke spasticity and surveyed the outcome of functional activity.Sixty patients were randomized into 3 groups. Group A patients received 1 session of rESWT per week for 3 consecutive weeks; group B patients received a single session of rESWT; group C patients received one session of sham rESWT per week for 3 consecutive weeks. The primary outcome was Modified Ashworth Scale of hand and wrist, whereas the secondary outcomes were Fugl-Meyer Assessment of hand function and wrist control. Evaluations were performed before the first rESWT treatment and immediately 1, 4, 8, 12, and 16 weeks after the last session of rESWT.Compared to the control group, the significant reduction in spasticity of hand and wrist lasted at least 16 and 8 weeks in group A and B, respectively. Three sessions of rESWT had a longer-lasting effect than one session. Furthermore, the reduction in spasticity after 3 sessions of rESWT may be beneficial for hand function and wrist control and the effect was maintained for 16 and 12 weeks, respectively.rESWT may be valuable in decreasing spasticity of the hand and wrist with accompanying enhancement of wrist control and hand function in chronic stroke patients.

    To evaluate the efficacy and safety of moxifloxacin versus ofloxacin plus metronidazole in patients with uncomplicated pelvic inflammatory disease (uPID; defined as PID symptoms and signs, but no complications such as septicemia, perihepatitis, and tubo-ovarian abscess) in Turkey. This was a multicenter, prospective, randomized, parallel-group study conducted between June 2010 and March 2013 in four hospitals in Turkey. Women received a 14-day course of either oral moxifloxacin at 400mg once daily (n = 560) or oral ofloxacin at 400mg twice daily plus oral metronidazole at 500 mg twice daily (n = 543). A total of 1156 women were randomized to the study. Total compliance was achieved in 1103 patients. For the primary measure of efficacy (clinical cure), moxifloxacin showed no difference compared with ofloxacin plus metronidazole (445/560 [79.5%] vs. 449/543 [82.7%]; p = 0.172). Bacteriological cure rates were high and comparable between treatment arms (99/119 [83.2%] vs. 93/110 [84.5%]; p = 0.781). Drug-related adverse events occurred less frequently with moxifloxacin than with ofloxacin plus metronidazole (210/560 [37.5%] vs. 252/543 [46.4%]; p = 0.003). Furthermore, moxifloxacin treatment was lower in cost and achieved higher patient compliance compared with ofloxacin plus metronidazole (31.4 Euros vs. 23.4 Euros and 7/578 (1.2%) vs. 22/578 (3.8%), respectively; p = 0.005). In patients with uPID, once-daily moxifloxacin monotherapy was clinically and microbiologically as efficacious as twice-daily ofloxacin plus metronidazole therapy and was associated with fewer drug-related adverse events, lower patient non-compliance, and a lower treatment cost.

    To describe the clinical efficacy of the treatment of Sjögren's syndrome dry eye using 0.03% tacrolimus eye drop. Prospective double-blind randomized study. Institutional outpatient clinic. Forty-eight eyes of twenty-four patients with dry eye related to Sjögren syndrome were enrolled in this study. The patients were randomized in 2 groups: tacrolimus (n=14) and vehicle (n=10) group. The tacrolimus group received a vial containing tacrolimus 0.03% (almond oil as vehicle) and the other group received the almond oil vehicle. All patients were instructed to use the eye drops every 12h in the lower conjunctival sac. Schirmer I test, break-up-time (BUT), corneal fluorescein and Rose Bengal staining scores were evaluated in all patients one day before the treatment (baseline), 7, 14, 28 and 90 days after treatment with the eye drops. The average fluorescein and Rose Bengal scores improved statistically after 7 days of treatment and even more after 90 days. The average Schirmer I and BUT values were unchanged after 7, 14 and 21 days but did show an improvement relative to baseline after 28 days of treatment. Schirmer I, BUT, fluorescein and Rose Bengal did not show any statistical significance in the vehicle group. Topical 0.03% tacrolimus eye drop improved tear stability and ocular surface status in cases of inflammatory or SS-related dry eye. ClinicalTrials.gov Identifier: NCT01850979.
