    OBJECTIVES A prospective randomized multicentre trial was performed to analyse the efficacy of a vest (Posthorax support vest®) to prevent sternal wound infection after cardiac surgery, and to identify risk factors. METHODS From September 2007 to March 2010, 2539 patients undergoing cardiac surgery via median sternotomy were prospectively randomized into those who received a Posthorax® vest and those who did not. Patients were instructed to wear the vest postoperatively for 24 h a day for at least 6 weeks; the duration of follow-up was 90 days. Patients who did not use the vest within a period of 72 h postoperatively were regarded as study dropouts. Statistical calculations were based on an intention-to-treat (ITT) analysis. Further evaluations comprised all subgroups of patients. RESULTS Complete data were available for 2539 patients (age 67 ± 11years, 45% female). Of these, 1351 were randomized to receive a vest, while 1188 received no vest. No significant differences were observed between groups regarding age, gender, diabetes, body mass index, chronic obstructive pulmonary disease (COPD), renal failure, the logistic EuroSCORE and the indication for surgery. The frequency of deep wound complications (dWC: mediastinitis and sternal dehiscence) was significantly lower in vest (n = 14; 1.04%) vs non-vest (n = 27; 2.27%) patients (ITT, P < 0.01), but superficial complications did not differ between groups. Subanalysis of vest patients revealed that only 933 (Group A) wore the vest according to the protocol, while 202 (Group BR) refused to wear the vest (non-compliance) and 216 (Group BN) did not use the vest for other reasons. All dWC occurred in Groups BR (n = 7) and BN (n = 7), although these groups had the same preoperative risk profile as Group A. Postoperatively, Group BN had a prolonged intubation time, a longer stay in the intensive care unit, greater use of intra-aortic balloon pump, higher frequency of COPD and a larger percentage of patients who

    2014-01-01

    Background Oral presentations of clinical cases by medical students during medical rounds in hospital wards are a source of anxiety and little is known about how this anxiety can be alleviated. The objective of this study was to investigate whether video-based feedback of public oral presentations can reduce anxiety in 4th year medical students. Methods Multicentre randomized study conducted in six intensive care units (ICU) and emergency departments (ED) in France over a 9-month period in 2012. One hundred and forty two 4th year medical students were randomized to two groups: intervention and control. Students in the intervention group were recorded while making an oral presentation of a patient during morning ward rounds, followed by video-based feedback. Students in the control group conducted presented classical oral presentations without being filmed and with no formal feedback. Anxiety levels during a public oral presentation were assessed using the Spielberger State Anxiety Inventory (STAI-S). The primary outcome was the difference in STAI-S scores between groups at the beginning and at the end of a 3-month ICU or ED internship. Results Seventy four students were randomized to the ‘video-based feedback’ group and 68 were randomized to the control group. In both groups, STAI-S scores were significantly lower after 3 months of internship. However, the reduction in STAI-S scores was significantly greater in the “video-based feedback” group than in controls (-9.2 ± 9.3 vs. –4.6 ± 8.2, p = 0.024. Compared to the control group, significantly fewer students with high-level anxiety were observed in the “video-based feedback” group after 3 months of internship (68 vs. 28%, p <0.001). Conclusions Compared to “usual practice”, video-assisted oral feedback reduced anxiety and significantly decreased the proportion of students experiencing severe anxiety. PMID:24885005

    The aim of this multicentre, prospective, randomised, dose-ranging study was to compare the safety and efficacy of subcutaneous recombinant hirudin (HBW 023) against intravenous sodium heparin in acute lower limb deep venous thrombosis (DVT). Patients were randomized to treatment with either HBW 023 or heparin for 5 +/- 1 days. HBW 023 was given according to body-weight in three dose groups. Thromboembolic disease was assessed by phlebography and ventilation/perfusion (V/Q) scanning on Day 1 and Day 5 +/- 1. One hundred and fifty-five patients were enrolled, of these 121 were evaluable for efficacy analysis. Significantly fewer patients on HBW 023 developed new V/Q abnormalities during the treatment period, (p = 0.006). There was no difference between the groups in thrombus extension or regression, major bleeding complications or serious adverse events. There were significantly fewer findings of new V/Q mismatch after treatment with HBW 023, and anticoagulant control was superior in these patients. PMID:9184388

    Acute hepatitis B virus (aHBV) infection can lead to fulminant liver failure, which likely is prevented by early lamivudine therapy. Even nonfulminant but severe acute hepatitis B can lead to significant morbidity and impaired quality of life. Therefore, lamivudine was evaluated in patients with severe aHBV in a placebo-controlled trial. Patients with severe aHBV infection (ALT >10× ULN, bilirubin >85 μm, prothrombin time >50%) were prospectively treated with lamivudine 100 mg/day or with placebo within 8 days after the diagnosis. The primary end point was time to bilirubin <34.2 μm. Secondary end points were time to clear HBsAg and HBV-DNA, development of anti-HBs and normalization of ALT. Eighteen cases were randomized to lamivudine, 17 to placebo. 94% of patients were hospitalized. No individual progressed to hepatic failure; all but one patient achieved the primary end point. Due to smaller than expected patient numbers, all study end points did not become statistically significant between treatment arms. Median time end points [in days] were bilirubin <34.2 μm (26.5 vs 32), ALT normalization (35 vs 48) and HBsAg clearance (48 vs 67) referring to earlier recovery under lamivudine, in contrast to loss of HBV-DNA (62 vs 54) and development of anti-HBs (119 vs 109). In all but two patients (one in every group), HBsAg clearance was reached in the study. Adverse events occurred more frequently during lamivudine therapy, but did not reach statistical significance. Lamivudine may ameliorate severe aHBV infection, but limited patient numbers prevented definite conclusions. PMID:24329913

    Anterior cervical plate fixation is an approved surgical technique for cervical spine stabilization in the presence of anterior cervical instability. Rigid plate design with screws rigidly locked to the plate is widely used and is thought to provide a better fixation for the treated spinal segment than a dynamic design in which the screws may slide when the graft is settling. Recent biomechanical studies showed that dynamic anterior plates provide a better graft loading possibly leading to accelerated spinal fusion with a lower incidence of implant complications. This, however, was investigated in vitro and does not necessarily mean to be the case in vivo, as well. Thus, the two major aspects of this study were to compare the speed of bone fusion and the rate of implant complications using either rigid- or dynamic plates. The study design is prospective, randomized, controlled, and multi-centric, having been approved by respective ethic committees of all participating sites. One hundred and thirty-two patients were included in this study and randomly assigned to one of the two groups, both undergoing routine level-1- or level-2 anterior cervical discectomy with autograft fusion receiving either a dynamic plate with screws being locked in ap - position (ABC, Aesculap, Germany), or a rigid plate (CSLP, Synthes, Switzerland). Segmental mobility and implant complications were compared after 3- and 6 months, respectively. All measurements were performed by an independent radiologist. Mobility results after 6 months were available for 77 patients (43 ABC/34 CSLP). Mean segmental mobility for the ABC group was 1.7 mm at the time of discharge, 1.4 mm after 3 months, and 0.8 mm after 6 months. For the CSLP- group the measurements were 1.0, 1.8, and 1.7 mm, respectively. The differences of mean segmental mobility were statistically significant between both groups after 6 months (P = 0.02). Four patients of the CSLP-group demonstrated surgical hardware complications

    To evaluate whether, by using an arthropump (irrigation equipment with pressure sensor), pneumatic tourniquet use could interfere with the duration of surgery, recovery of movement and joint volume in patients who underwent knee videoarthroscopy for partial meniscectomy. Methods: 103 patients divided randomly into two groups regarding use or nonuse of a pneumatic tourniquet were evaluated in five different centers by seven different surgeons. The variables were evaluated during the surgery and seven days after the operation. Results: No statistically significant differences were found among any of the variables studied. Conclusion: There are no reasons that would either justify or discredit tourniquet use in this specific situation. PMID:27022588

    Background This multicentre, randomized clinical trial assessed the safety and effectiveness of the EVARREST™ Fibrin Sealant Patch (FP) in treating parenchymal bleeding following anatomic and non-anatomic liver resections. Methods One hundred and two patients were stratified according to the type of hepatic resection (anatomic/non-anatomic), and randomized (1:1) after identification of an appropriate bleeding site, to FP vs Standard of Care (SoC, manual compression ± topical haemostat). The primary endpoint was haemostasis at 4 min from bleeding site identification with no re-bleeding requiring re-treatment. Results The FP was superior in achieving haemostasis at 4 min (96%, 48/50) to SoC (46%, 24/52; p < 0.001). Stratification for resection type showed treatment differences for primary endpoint for anatomic (24/25 FP vs 13/23 SoC; p = 0.001) and non-anatomic liver resections (24/25FP vs 11/29 SoC; p < 0.001). Adverse events related to the study procedure were reported in 40/50 patients (80%) in the FP group and 43/52 patients (83%) in the SoC group. One (2%) adverse event (infected intra-abdominal fluid collection) was possibly related to study treatment. Conclusion This clinical trial confirms that the FP is safe and highly effective in controlling parenchymal bleeding following hepatectomy regardless of the type of resection.

    This study was a prospective, parallel-group, randomized, double-blind, vehicle-controlled, multi-centre clinical trial to compare the efficacy of topical sertaconazole 2% cream with vehicle in reducing chronic pruritus in subjects with atopic dermatitis, and to assess its safety and local tolerability. A total of 70 subjects applied either of the 2 treatments twice daily for a period of 4 weeks on affected, itchy skin areas. Treatment efficacy was evaluated primarily considering the item itch intensity on a 5-point verbal rating scale. Insomnia, state of atopic dermatitis (Scoring Atopic Dermatitis; SCORAD), quality of life and therapy benefit were also assessed. No significant difference between active treatment and vehicle was found at any of the time-points for any of the investigated parameters. Under the experimental conditions of the study, sertaconazole 2% cream did not exert anti-pruritic effects that were better than vehicle in subjects with atopic dermatitis who had chronic pruritus.

    Herpes simplex virus (HSV) is one of the most commonly identified infectious aetiologies of encephalitis in North America and Europe. The epidemiology of encephalitis beyond these regions, however, is poorly defined. During 2009-2012 we enrolled 313 patients in a multicentre prospective study of encephalitis in Peru, 45 (14·4%) of whom had confirmed HSV infection. Of 38 patients with known HSV type, 84% had HSV-1 and 16% had HSV-2. Patients with HSV infection were significantly more likely to present in the summer months (44·4% vs. 20·0%, P = 0·003) and have nausea (60·0% vs. 39·8%, P = 0·01) and rash (15·6% vs. 5·3%, P = 0·01) compared to patients without HSV infection. These findings highlight differences in the epidemiology and clinical presentation of HSV encephalitis outside of the Northern Hemisphere that warrant further investigation. Furthermore, there is an urgent need for improved HSV diagnostic capacity and availability of intravenous acyclovir in Peru. PMID:26733400

    Objectives To validate recent guidance changes by establishing the performance of cut-off values for embryo crown-rump length and mean gestational sac diameter to diagnose miscarriage with high levels of certainty. Secondary aims were to examine the influence of gestational age on interpretation of mean gestational sac diameter and crown-rump length values, determine the optimal intervals between scans and findings on repeat scans that definitively diagnose pregnancy failure.) Design Prospective multicentre observational trial. Setting Seven hospital based early pregnancy assessment units in the United Kingdom. Participants 2845 women with intrauterine pregnancies of unknown viability included if transvaginal ultrasonography showed an intrauterine pregnancy of uncertain viability. In three hospitals this was initially defined as an empty gestational sac <20 mm mean diameter with or without a visible yolk sac but no embryo, or an embryo with crown-rump length <6 mm with no heartbeat. Following amended guidance in December 2011 this definition changed to a gestational sac size <25 mm or embryo crown-rump length <7 mm. At one unit the definition was extended throughout to include a mean gestational sac diameter <30 mm or embryo crown-rump length <8 mm. Main outcome measures Mean gestational sac diameter, crown-rump length, and presence or absence of embryo heart activity at initial and repeat transvaginal ultrasonography around 7-14 days later. The final outcome was pregnancy viability at 11-14 weeks’ gestation. Results The following indicated a miscarriage at initial scan: mean gestational sac diameter ≥25 mm with an empty sac (364/364 specificity: 100%, 95% confidence interval 99.0% to 100%), embryo with crown-rump length ≥7 mm without visible embryo heart activity (110/110 specificity: 100%, 96.7% to 100%), mean gestational sac diameter ≥18 mm for gestational sacs without an embryo presenting after 70 days’ gestation (907/907 specificity: 100%, 99.6% to

    Background Cachexia, a >10% loss of body-weight, is one factor determining the poor prognosis of pancreatic cancer. Deficiency of L-Carnitine has been proposed to cause cancer cachexia. Findings We screened 152 and enrolled 72 patients suffering from advanced pancreatic cancer in a prospective, multi-centre, placebo-controlled, randomized and double-blinded trial to receive oral L-Carnitine (4 g) or placebo for 12 weeks. At entry patients reported a mean weight loss of 12 ± 2,5 (SEM) kg. During treatment body-mass-index increased by 3,4 ± 1,4% under L-Carnitine and decreased (−1,5 ± 1,4%) in controls (p < 0,05). Moreover, nutritional status (body cell mass, body fat) and quality-of-life parameters improved under L-Carnitine. There was a trend towards an increased overall survival in the L-Carnitine group (median 519 ± 50 d versus 399 ± 43 d, not significant) and towards a reduced hospital-stay (36 ± 4d versus 41 ± 9d,n.s.). Conclusion While these data are preliminary and need confirmation they indicate that patients with pancreatic cancer may have a clinically relevant benefit from the inexpensive and well tolerated oral supplementation of L-Carnitine.

    Although sofosbuvir has been approved for patients with genotypes 2/3 (G2/3), many parts of the world still consider pegylated Interferon alpha (P) and ribavirin (R) as standard of care for G2/3. Patients with rapid virological response (RVR) show response rates >80%. However, SVR (sustained virological response) in non-RVR patients is not satisfactory. Longer treatment duration may be required but evidence from prospective trials are lacking. A total of 1006 chronic HCV genotype 2/3 patients treated with P/R were recruited into a German HepNet multicenter screening registry. Of those, only 226 patients were still HCV RNA positive at week 4 (non-RVR). Non-RVR patients with ongoing response after 24 weeks P-2b/R qualified for OPTEX, a randomized trial investigating treatment extension of additional 24 weeks (total 48 weeks, Group A) or additional 12 weeks (total 36 weeks, group B) of 1.5 μg/kg P-2b and 800-1400 mg R. Due to the low number of patients without RVR, the number of 150 anticipated study patients was not met and only 99 non-RVR patients (n=50 Group A, n=49 Group B) could be enrolled into the OPTEX trial. Baseline factors did not differ between groups. Sixteen patients had G2 and 83 patients G3. Based on the ITT (intention-to-treat) analysis, 68% [55%; 81%] in Group A and 57% [43%; 71%] in Group B achieved SVR (p= 0.31). The primary endpoint of better SVR rates in Group A compared to a historical control group (SVR 70%) was not met. In conclusion, approximately 23% of G2/3 patients did not achieve RVR in a real world setting. However, subsequent recruitment in a treatment-extension study was difficult. Prolonged therapy beyond 24 weeks did not result in higher SVR compared to a historical control group. Trial Registration ClinicalTrials.gov NCT00803309 PMID:26057627

    A year long multicentre prospective study was carried out in the Valencia region of Spain, to determine the cause of community acquired pneumonia. The study was based on 510 of 833 patients with pneumonia. Of these, 462 were admitted to hospital, where 31 patients died. A cause was established in only 281 cases--208 of bacterial, 60 of viral, and 13 of mixed infection. The most common microorganisms were Streptococcus pneumoniae (14.5%), Legionella sp (14%), Influenza virus (8%), and Mycoplasma pneumoniae (4%). There was a higher incidence of Legionella sp than in other studies. PMID:1908605

    Many studies still indicate insufficient pain management after surgery, e.g., in patients after small- or medium-size operations. Yet it is still uncertain if postoperative pain based on patient-related outcomes can be improved by implementing guideline-related programmes in a multicentre approach. Adult patients in six hospitals in one German city were included in this prospective study. Data collection took place twice in each hospital, once before and once after implementation of concepts and in-house training. Pain and pain-related aspects were assessed one day after surgery and compared between the pre- and post-test group including subgroup analysis of certain surgical procedures by using Student’s t-tests, Mann-Whitney U tests and chi-square tests (alphatwo-tailed = 0.05). Overall, pain at rest and during movement was slightly lower after the intervention. Significant changes were observed after thoracic surgery, small joint surgery and other minor surgical procedures. The rather moderate decrease in pain likely relates to a reasonable pre-existing pain management and to detached improvements in certain patient subgroups. Interestingly, specific analyses revealed significantly lower post-test pain as compared to pre-test pain only in patients without pre-existing chronic pain. Side effects related to pain medication were significantly lower after intervention. Our data show, for the first time, benefits of a perioperative teaching programme in a multicentre approach. Pain ratings improved mainly in specific subgroups of patients, e.g., small surgical procedures and patients without preoperative pain. Thus, general improvement is possible but special attention should be paid to the group of patients with preoperative pain. PMID:26600464

    Objectives To compare 6 month and 12 month health status and functional outcomes between regional major trauma registries in Hong Kong and Victoria, Australia. Summary Background Data Multicentres from trauma registries in Hong Kong and the Victorian State Trauma Registry (VSTR). Methods Multicentre, prospective cohort study. Major trauma patients and aged ≥18 years were included. The main outcome measures were Extended Glasgow Outcome Scale (GOSE) functional outcome and risk-adjusted Short-Form 12 (SF-12) health status at 6 and 12 months after injury. Results 261 cases from Hong Kong and 1955 cases from VSTR were included. Adjusting for age, sex, ISS, comorbid status, injury mechanism and GCS group, the odds of a better functional outcome for Hong Kong patients relative to Victorian patients at six months was 0.88 (95% CI: 0.66, 1.17), and at 12 months was 0.83 (95% CI: 0.60, 1.12). Adjusting for age, gender, ISS, GCS, injury mechanism and comorbid status, Hong Kong patients demonstrated comparable mean PCS-12 scores at 6-months (adjusted mean difference: 1.2, 95% CI: −1.2, 3.6) and 12-months (adjusted mean difference: −0.4, 95% CI: −3.2, 2.4) compared to Victorian patients. Keeping age, gender, ISS, GCS, injury mechanism and comorbid status, there was no difference in the MCS-12 scores of Hong Kong patients compared to Victorian patients at 6-months (adjusted mean difference: 0.4, 95% CI: −2.1, 2.8) or 12-months (adjusted mean difference: 1.8, 95% CI: −0.8, 4.5). Conclusion The unadjusted analyses showed better outcomes for Victorian cases compared to Hong Kong but after adjusting for key confounders, there was no difference in 6-month or 12-month functional outcomes between the jurisdictions.

    The objective of this study was to evaluate the efficacy of treating chronic idiopathic urticaria (CIU) with levamisole in combination with levocetirizine. This was a multicentre, randomized, double-blind, controlled trial that included 132 patients with active CIU who were treated for 6 weeks with either levocetirizine alone (control group; n = 65) or levamisole plus levocetirizine (treatment group; n = 67). Response to therapy was evaluated by measuring the efficacy rate. After 2 weeks of treatment, there was no significant difference in the efficacy rate between the treatment and control groups (54.84% and 42.37%, respectively). After 6 weeks of treatment, a statistically significant difference in the efficacy rate was observed between the groups (76.27% and 54.39% for the treatment and control groups, respectively). This study demonstrated that a combination of levamisole plus levocetirizine is more effective than levocetirizine alone and potentially provides a new, promising approach to the treatment of CIU.

    2013-01-01

    Background Crisis resolution teams (CRTs) provide intensive alternative care to hospital admission for patients with mental health crises. The aims of this study were to describe the proportions and characteristics of patients admitted to in-patient wards from CRTs, to identify any differences in admission practices between CRTs, and to identify predictors of admissions from CRTs. Methods A naturalistic prospective multicentre design was used to study 680 consecutive patients under the care of eight CRTs in Norway over a 3-month period in 2005/2006. Socio-demographic and clinical data were collected on the patients, and on the organization and operation of the CRTs. Logistic regression analysis for hierarchical data was used to test potential predictors of admission at team and patient level. Results One hundred and forty-six patients (21.5%) were admitted to in-patient wards. There were significant differences in admission rates between the CRTs. The likelihood of being admitted to an in-patient ward was significantly lower for patients treated by CRTs that operated during extended opening hours than CRTs that operated during office hours only. Those most likely to be admitted were patients with psychotic symptoms, suicidal risk, and a prior history of admissions. Conclusions Extended opening hours may help CRTs to prevent more admissions for patients with moderately severe and relapsing mental illnesses. Patients with severe psychosis seem to be difficult to treat in the community by Norwegian CRTs even with extended opening hours. PMID:23594922

    Background. Haptic robots allow the exploitation of known motor learning mechanisms, representing a valuable option for motor treatment after stroke. The aim of this feasibility multicentre study was to test the clinical efficacy of a haptic prototype, for the recovery of hand function after stroke. Methods. A prospective pilot clinical trial was planned on 15 consecutive patients enrolled in 3 rehabilitation centre in Italy. All the framework features of the haptic robot (e.g., control loop, external communication, and graphic rendering for virtual reality) were implemented into a real-time MATLAB/Simulink environment, controlling a five-bar linkage able to provide forces up to 20 [N] at the end effector, used for finger and hand rehabilitation therapies. Clinical (i.e., Fugl-Meyer upper extremity scale; nine hold pegboard test) and kinematics (i.e., time; velocity; jerk metric; normalized jerk of standard movements) outcomes were assessed before and after treatment to detect changes in patients' motor performance. Reorganization of cortical activation was detected in one patient by fMRI. Results and Conclusions. All patients showed significant improvements in both clinical and kinematic outcomes. Additionally, fMRI results suggest that the proposed approach may promote a better cortical activation in the brain. PMID:24319496

    Background. Haptic robots allow the exploitation of known motor learning mechanisms, representing a valuable option for motor treatment after stroke. The aim of this feasibility multicentre study was to test the clinical efficacy of a haptic prototype, for the recovery of hand function after stroke. Methods. A prospective pilot clinical trial was planned on 15 consecutive patients enrolled in 3 rehabilitation centre in Italy. All the framework features of the haptic robot (e.g., control loop, external communication, and graphic rendering for virtual reality) were implemented into a real-time MATLAB/Simulink environment, controlling a five-bar linkage able to provide forces up to 20 [N] at the end effector, used for finger and hand rehabilitation therapies. Clinical (i.e., Fugl-Meyer upper extremity scale; nine hold pegboard test) and kinematics (i.e., time; velocity; jerk metric; normalized jerk of standard movements) outcomes were assessed before and after treatment to detect changes in patients' motor performance.

    Introduction Owing to increasing numbers of decompressive craniectomies in patients with malignant middle cerebral artery infarction, cranioplastic surgery becomes more relevant. However, the current literature mainly consists of retrospective single-centre (evidence class III) studies. This leads to a wide variability of technical approaches and clinical outcomes. To improve our knowledge about the key elements of cranioplasty, which may help optimising clinical treatment and long-term outcome, a prospective multicentre registry across Germany, Austria and Switzerland will be established. Methods All patients undergoing cranioplastic surgery in participating centres will be invited to join the registry. Technical methods, materials, medical history, adverse events and clinical outcome measures, including modified Rankin scale and EQ-5D, will be assessed at several time points. Patients will be accessible to inclusion either at initial decompressive surgery or when cranioplasty is planned. Scheduled monitoring will be carried out at time of inclusion and subsequently at time of discharge, if any readmission is necessary, and at follow-up presentation. Cosmetic results and patient satisfaction will also be assessed. Collected data will be managed and statistically analysed by an independent biometric institute. The primary endpoint will be mortality, need for operative revision and neurological status at 3 months following cranioplasty. Ethics and dissemination Ethics approval was obtained at all participating centres. The registry will provide reliable prospective evidence on surgical techniques, used materials, adverse events and functional outcome, to optimise patient treatment. We expect this study to give new insights in the treatment of skull defects and to provide a basis for future evidence-based therapy regarding cranioplastic surgery.

    2012-01-01

    Background Malaria continues to be amongst the most frequent infectious diseases imported to Europe. Whilst European treatment guidelines are based on data from studies carried out in endemic areas, there is a paucity of original prospective treatment data. The objective was to summarize data on treatments to harmonize and optimize treatment for uncomplicated malaria in Europe. Methods A prospective observational multicentre study was conducted, assessing tolerance and efficacy of treatment regimens for imported uncomplicated falciparum malaria in adults amongst European centres of tropical and travel medicine. Results Between December 2003 and 2009, 504 patients were included in 16 centres from five European countries. Eighteen treatment regimens were reported, the top three being atovaquone-proguanil, mefloquine, and artemether-lumefantrine. Treatments significantly differed with respect to the occurrence of treatment changes (p = 0.005) and adverse events (p = 0.001), parasite and fever clearance times (p < 0.001), and hospitalization rates (p = 0.0066) and durations (p = 0.001). Four recrudescences and two progressions to severe disease were observed. Compared to other regimens, quinine alone was associated with more frequent switches to second line treatment, more adverse events and longer inpatient stays. Parasite and fever clearance times were shortest with artemether-mefloquine combination treatment. Vomiting was the most frequent cause of treatment change, occurring in 5.5% of all patients but 9% of the atovaquone-proguanil group. Conclusions This study highlights the heterogeneity of standards of care within Europe. A consensus discussion at European level is desirable to foster a standardized management of imported falciparum malaria. PMID:22720832

    We aimed to describe the epidemiology of Rapid Response Team (RRT) activation in New Zealand public hospitals. We undertook a prospective multicentre observational study of RRT activations in 11 hospitals for consecutive 14-day periods during October-December 2014. A standardised case report form was used to collect data on patient demographics, RRT activation criteria and timing, vital signs on RRT arrival, team composition and intervention, treatment limitation and patient outcome at day 30. Three hundred and thirteen patients received 351 RRT calls during the study period. Patients were admitted under a medical specialty in 177 (56.5%) instances. Median duration from hospital admission to first RRT call was two days. Eighty-six percent of RRT calls were to inpatient wards. A total of 43.4% of RRT calls occurred between 0800 and 1700 hours (38% of the day) and 75.5% of RRT calls were activated by ward nurses. A median of three staff attended each call. Common triggers for RRT activation were increased Early Warning Score (56.2%) and staff concern (25.7%). During the RRT call, 2.8% of patients died; 19.8% died by day 30. New 'Not For Resuscitation' orders were written in 22.5% of RRT calls. By day 30, 56.2% of patients had been discharged home alive. In conclusion, RRTs in New Zealand are multidisciplinary, mostly nurse-activated and predominantly respond to deteriorating medical (rather than surgical) patients. Most patients remain on the ward. The RRT frequently implements treatment limitations. Given almost one in five patients die within 30 days, over half of whom die within 72 hours of RRT review, surviving the RRT call may provide false reassurance that the patient will subsequently do well.

  3. Outcome of physiotherapy after surgery for cervical disc disease: a prospective randomised multi-centre trial

    PubMed Central

    2014-01-01

    Background Many patients with cervical disc disease require leave from work, due to long-lasting, complex symptoms, including chronic pain and reduced levels of physical and psychological function. Surgery on a few segmental levels might be expected to resolve disc-specific pain and reduce neurological deficits, but not the non-specific neck pain and the frequent illness. No study has investigated whether post-surgery physiotherapy might improve the outcome of surgery. The main purpose of this study was to evaluate whether a well-structured rehabilitation programme might add benefit to the customary post-surgical treatment for cervical disc disease, with respect to function, disability, work capability, and cost effectiveness. Methods/Design This study was designed as a prospective, randomised, controlled, multi-centre study. An independent, blinded investigator will compare two alternatives of rehabilitation. We will include 200 patients of working age, with cervical disc disease confirmed by clinical findings and symptoms of cervical nerve root compression. After providing informed consent, study participants will be randomised to one of two alternative physiotherapy regimes; (A) customary treatment (information and advice on a specialist clinic); or (B) customary treatment plus active physiotherapy. Physiotherapy will follow a standardised, structured programme of neck-specific exercises combined with a behavioural approach. All patients will be evaluated both clinically and subjectively (with questionnaires) before surgery and at 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery. The main outcome variable will be neck-specific disability. Cost-effectiveness will also be calculated. Discussion We anticipate that the results of this study will provide evidence to support physiotherapeutic rehabilitation applied after surgery for cervical radiculopathy due to cervical disc disease.

    Painful diabetic neuropathy (PDN) is a peripheral neuropathic pain condition that is often difficult to relieve. Spinal cord stimulation (SCS) is a proven effective therapy for various types of mixed neuropathic conditions, yet effectiveness of SCS treatment for PDN is not well established. To our knowledge, ours is the first multicentre randomized controlled trial investigating the effectiveness of SCS in patients with PDN. Sixty patients with PDN in the lower extremities refractory to conventional medical therapy were enrolled and followed for 6 months. They were randomized 2:1 to best conventional medical practice with (SCS group) or without (control group) additional SCS therapy, and both groups were assessed at regular intervals. At each follow-up visit, the EuroQoL 5D, the short form McGill Pain Questionnaire (SF-MPQ) and a visual analogue scale (VAS, ranging 0-100) to measure pain intensity were recorded. The average VAS score for pain intensity was 73 in the SCS group and 67 in the control group at baseline. After 6 months of treatment, the average VAS score was significantly reduced to 31 in the SCS group (P<.001) and remained 67 (P=.97) in the control group. The SF-MPQ and EuroQoL 5D questionnaires also showed that patients in the SCS group, unlike those in the control group, experienced reduced pain and improved health and quality of life after 6 months of treatment. In patients with refractory painful diabetic neuropathy, spinal cord stimulation therapy significantly reduced pain and improved quality of life. PMID:25180016

    Objectives Although tonsillectomy is one of the most frequent and painful surgeries, the association between baseline and process parameters and postoperative pain are not fully understood. Methods A multicentre prospective cohort study using a web-based registry enrolled 1,527 women and 1,008 men aged 4 to 85 years from 52 German hospitals between 2006 and 2015. Maximal pain (MP) score the first day after surgery on a numeric rating scale (NRS) from 0 (no pain) to 10 (MP) was the main outcome parameter. Results The mean maximal pain score was 5.8±2.2 (median 6). Multivariable analysis revealed that female gender (Odds ratio [OR] = 1.33; 95% confidence interval [CI] = 1.12 to 1.56; p = 0.001), age <20 years (OR = 1.56; CI = 1.27 to 1.91; p<0.0001), no pain counselling (OR = 1.78; CI = 1.370 to 2.316; p<0.001), chronic pain (OR = 1.34; CI = 1.107 to 1.64; p = 0.004), and receiving opioids in recovery room (OR = 1.89; CI = 1.55 to 2.325; p<0.001) or on ward (OR = 1.79; CI = 1.42 to 2.27; p<0.001) were independently associated with higher experienced maximal postoperative pain (greater the median of 6). The effect of age on pain was not linear. Maximal pain increased in underage patients to a peak at the age of 18 to 20 years. From the age of ≥20 years on, maximal pain after tonsillectomy continuously decreased. Even after adjustment to all statistically important baseline and process parameters, there was substantial variability of maximal pain between hospitals with a heterogeneity variance of 0.31. Conclusion Many patients seem to receive insufficient or ineffective analgesia after tonsillectomy. Further research should address if populations at risk of higher postoperative pain such as females, younger patients or those with preexisting pain might profit from a special pain management protocol. Beyond classical demographical and process parameters the large variability between different hospitals is striking and indicates the existence of other unknown factors

    2010-01-01

    Introduction Febrile neutropenia (FN) is common in cancer patients receiving myelotoxic therapy. The procedures to treat FN are well established in oncology, but it is unclear whether management is adequate in the emergency department (ED). Methods This prospective, multicentre, observational study was carried out in 47 French EDs for 6 months. Patients were adults presenting at the ED with FN after myelotoxic treatment for cancer. Severity of infection was defined according to Bone criteria for severe sepsis and septic shock (SS/SSh) and risk was determined according to Multinational Association of Supportive Care in Cancer (MASCC) criteria. The end point was the implementation of guidelines. Management of patients with SS/SSh required: (i) adequate intravenous (IV) antimicrobial therapy for the first 90 min (broad-spectrum beta-lactam with or without an aminoglycoside); (ii) fluid challenge (500 mL); (iii) lactate measurement; (iv) at least one blood culture; and (v) hospitalization. Management of patients without SS/SSh required: (1) no initiation of granulocyte - cell stimulating factor (G-CSF); (2) adequate IV antimicrobial therapy (broad-spectrum beta-lactam) and hospitalization if the patient was high-risk according to MASCC criteria; (3) adequate oral antimicrobial therapy (quinolone or amoxicillin/clavulanate or cephalosporin) and hospital discharge if the patient was low-risk. Results 198 patients were enrolled; 89 patients had SS/SSh, of whom 19 received adequate antimicrobial therapy within 90 min and 42 received appropriate fluid challenge. Blood cultures were obtained from 87 and lactate concentration was measured in 29. Overall, only 6 (7%) patients with SS/SSh received adequate management. Among 108 patients without SS/SSh, 38 (35%) were high-risk and 70 (65%) low-risk. In the high-risk group, adequate antimicrobial therapy was given to 31 patients, G-CSF was initiated in 4 and 35 were hospitalized. In the low-risk group, 4 patients received

    Background Diabetic nephropathy (DN) is one of the major late complications of diabetes. Treatment aimed at slowing down the progression of DN is available but methods for early and definitive detection of DN progression are currently lacking. The ‘Proteomic prediction and Renin angiotensin aldosterone system Inhibition prevention Of early diabetic nephRopathy In TYpe 2 diabetic patients with normoalbuminuria trial’ (PRIORITY) aims to evaluate the early detection of DN in patients with type 2 diabetes (T2D) using a urinary proteome-based classifier (CKD273). Methods In this ancillary study of the recently initiated PRIORITY trial we aimed to validate for the first time the CKD273 classifier in a multicentre (9 different institutions providing samples from 165 T2D patients) prospective setting. In addition we also investigated the influence of sample containers, age and gender on the CKD273 classifier. Results We observed a high consistency of the CKD273 classification scores across the different centres with areas under the curves ranging from 0.95 to 1.00. The classifier was independent of age (range tested 16–89 years) and gender. Furthermore, the use of different urine storage containers did not affect the classification scores. Analysis of the distribution of the individual peptides of the classifier over the nine different centres showed that fragments of blood-derived and extracellular matrix proteins were the most consistently found. Conclusion We provide for the first time validation of this urinary proteome-based classifier in a multicentre prospective setting and show the suitability of the CKD273 classifier to be used in the PRIORITY trial.

    The U-SENS™ is a test method based on the human myeloid U937 cell line to assess the skin sensitisation potential of substances. To demonstrate its robustness, a multicentre validation study with four laboratories testing 24 coded substances has been conducted according to internationally agreed principles. The primary objective of the study was to enlarge the U-SENS™'s reproducibility database. Secondary objectives were to provide additional evidence on its transferability and its predictive capability. Reproducibility within laboratories was approximately 92%, while the reproducibility between laboratories was 87.5%. Predictivity for the 24 validation substances was high, with sensitivity, specificity and accuracy being on average at least 93.8%. Similar performances are obtained for 38 substances when combining the study results with those of an earlier multicentre study, as well as with an automated version of the U-SENS™. With reliability and relevance similar to comparable non-animal skin sensitisation test methods, which have achieved regulatory acceptance, it is concluded that the U-SENS™ is a well reproducible and predictive test method. This profiles the U-SENS™ as a valuable addition to the suite of non-animal testing methods for skin sensitisation with the potential to significantly contribute to the development of integrated testing strategies.

    Background Several randomized controlled trials have compared different suture materials and techniques for abdominal wall closure with respect to the incidence of incisional hernias after midline laparotomy and shown that it remains, irrespective of the methods used, considerably high, ranging from 9% to 20%. The development of improved suture materials which would reduce postoperative complications may help to lower its frequency. Design This is a historically controlled, single-arm, multi-centre, prospective trial to evaluate the safety of MonoMax® suture material for abdominal wall closure in 150 patients with primary elective midline incisions. INSECT patients who underwent abdominal closure using Monoplus® and PDS® will serve as historical control group. The incidences of wound infections and of burst abdomen are defined as composite primary endpoints. Secondary endpoints are the frequency of incisional hernias within one year after operation and safety. To ensure adequate comparability in surgical performance and recruitment, the 4 largest centres of the INSECT-Trial will participate. After hospital discharge, the investigators will examine the enrolled patients again at 30 days and at 12 ± 1 months after surgery. Conclusion This historically controlled, single-arm, multi-centre, prospective ISSAAC trial aims to assess whether the use of an ultra-long-lasting absorbable monofilament suture material is safe and efficient.

    Objective To assess the risks and benefits associated with caesarean delivery compared with vaginal delivery. Design Prospective cohort study within the 2005 WHO global survey on maternal and perinatal health. Setting 410 health facilities in 24 areas in eight randomly selected Latin American countries; 123 were randomly selected and 120 participated and provided data Participants 106 546 deliveries reported during the three month study period, with data available for 97 095 (91% coverage). Main outcome measures Maternal, fetal, and neonatal morbidity and mortality associated with intrapartum or elective caesarean delivery, adjusted for clinical, demographic, pregnancy, and institutional characteristics. Results Women undergoing caesarean delivery had an increased risk of severe maternal morbidity compared with women undergoing vaginal delivery (odds ratio 2.0 (95% confidence interval 1.6 to 2.5) for intrapartum caesarean and 2.3 (1.7 to 3.1) for elective caesarean). The risk of antibiotic treatment after delivery for women having either type of caesarean was five times that of women having vaginal deliveries. With cephalic presentation, there was a trend towards a reduced odds ratio for fetal death with elective caesarean, after adjustment for possible confounding variables and gestational age (0.7, 0.4 to 1.0). With breech presentation, caesarean delivery had a large protective effect for fetal death. With cephalic presentation, however, independent of possible confounding variables and gestational age, intrapartum and elective caesarean increased the risk for a stay of seven or more days in neonatal intensive care (2.1 (1.8 to 2.6) and 1.9 (1.6 to 2.3), respectively) and the risk of neonatal mortality up to hospital discharge (1.7 (1.3 to 2.2) and 1.9 (1.5 to 2.6), respectively), which remained higher even after exclusion of all caesarean deliveries for fetal distress. Such increased risk was not seen for breech presentation. Lack of labour was a risk factor

  11. The optimized acupuncture treatment for neck pain caused by cervical spondylosis: a study protocol of a multicentre randomized controlled trial

    PubMed Central

    2012-01-01

    Background Neck pain is one of the chief symptoms of cervical spondylosis (CS). Acupuncture is a well-accepted and widely used complementary therapy for the management of neck pain caused by CS. In this paper, we present a randomized controlled trial protocol evaluating the use of acupuncture for CS neck pain, comparing the effects of the optimized acupuncture therapy in real practice compared with sham and shallow acupuncture. Methods/Design This trial uses a multicentre, parallel-group, randomized, sham acupuncture and shallow acupuncture, controlled single-blind design. Nine hospitals are involved as trial centres. 945 patients who meet inclusion criteria are randomly assigned to receive optimized acupuncture therapy, sham acupuncture or shallow acupuncture by a computerized central randomization system. The interventions past for 4 weeks with eight to ten treatments in total. The group allocations and interventions are concealed to patients and statisticians. The Northwick Park Neck Pain Questionnaire (NPQ) is used as the primary outcome measure, and the McGill Pain Questionnaire (MPQ) and The Short Form (36) Health Survey (SF-36) are applied as secondary outcome measures. The evaluation is performed at baseline, at the end of the intervention, and at the end of the first month and the third month during follow-up. The statistical analyses will include baseline data comparison and repeated measures of analysis of variance (ANOVA) for primary and secondary outcomes of group and time differences. Adverse events (AEs) will be reported if they occur. Discussion This trial is a multicentre randomized control trial (RCT) on the efficacy of acupuncture for CS neck pain and has a large sample size and central randomization in China. It will strictly follow the CONSORT statement and STRICTA extension guideline to report high-quality study results. By setting the control groups as sham and shallow acupuncture, this study attempts to reveal the effects of real acupuncture

    Following favourable results from a previous study, a large, multicentre, prospective, case-control study was performed to further assess the incidence of bleeding complications after dental extraction in patients taking oral anticoagulant therapy (OAT). Four hundred fifty-one patients being treated with warfarin who required dental extraction were compared with a control group of 449 non-anticoagulated subjects undergoing the same procedure. In the warfarin-treated group, the oral anticoagulant regimen was maintained unchanged, such that the patients had an International Normalised Ratio ranging between 1.8 and 4, and local haemostatic measures (i.e. fibrin sponges, silk sutures and gauzes saturated with tranexamic acid) were adopted. All the procedures were performed in an outpatient setting. Seven bleeding complications occurred in the OAT group and four in the control group; the difference in the number of bleeding events between the two groups was not statistically significant (OR=1.754; 95% CI 0.510 - 6.034; p=0.3727). No post-operative late bleeds requiring hospitalisation and/or blood transfusions were recorded, and the adjunctive local haemostatic measures were adequate to stop the bleeding. The results of our protocol applied in this large, multicenter study show that dental extractions can be performed easily and safely in anticoagulated outpatients without any modification of the ongoing anticoagulant therapy, thus minimising costs and reducing discomfort for patients.

    Objective A clinical diagnosis of bile acid malabsorption (BAM) can be confirmed using SeHCAT (tauroselcholic (75selenium) acid), a radiolabelled synthetic bile acid. However, while BAM can be the cause of chronic diarrhoea, it is often overlooked as a potential diagnosis. Therefore, we investigated the use of SeHCAT for diagnosis of BAM in UK hospitals. Design A multicentre survey was conducted capturing centre and patient-level information detailing patient care-pathways, clinical history, SeHCAT results, treatment with bile acid sequestrants (BAS), and follow-up in clinics. Eligible data from 38 centres and 1036 patients were entered into a validated management system. Results SeHCAT protocol varied between centres, with no standardised patient positioning, and differing referral systems. Surveyed patients had a mean age of 50 years and predominantly women (65%). The mean SeHCAT retention score for all patients was 19% (95% CI 17.8% to 20.3%). However, this differed with suspected BAM type: type 1: 9% (95% CI 6.3% to 11.4%), type 2: 21% (95% CI 19.2% to 23.0%) and type 3: 22% (95% CI 19.6% to 24.2%). Centre-defined ‘abnormal’ and ‘borderline’ results represented over 50% of the survey population. BAS treatment was prescribed to only 73% of patients with abnormal results. Conclusions The study identified a lack of consistent cut-off/threshold values, with differing centre criteria for defining an ‘abnormal’ SeHCAT result. BAS prescription was not related in a simple way to the SeHCAT result, nor to the centre-defined result, highlighting a lack of clear patient care-pathways. There is a clear need for a future diagnostic accuracy study and a better understanding of optimal management pathways. PMID:27252882

    Introduction Answering the demands of an increasingly young and active patient population, recent developments in total hip arthroplasty (THA) have shifted towards minimising tissue damage. The Collum Femoris Preserving (CFP) stem was developed to preserve the trochanteric region of the femur, which potentially preserves the insertion of the gluteus musculature. This might accelerate early postoperative rehabilitation and improve functional outcome. Currently the functional results of the CFP stem have not been compared with conventional straight stems in a randomised controlled trial (RCT). The primary purpose of this trial is to compare the functional result of CFP stem THA with conventional uncemented straight stem THA, measured by the Dutch Hip disability and Osteoarthritis Outcome Score (HOOS) at 3-month follow-up. Methods A prospective blinded multicentre RCT will be performed. We aim to recruit 150 patients. The patients will be randomly allocated to a THA with a straight or a curved stem. All patients, research assistants, clinical assessors and investigators will be blinded for the type of prosthesis for 5 years. Clinical assessments and roentgenograms will be taken preoperative, at 6 weeks after surgery, at 1, 2, 3, 4 and 5 years after surgery. Patient reported outcome measures (PROMs) will be obtained at the same follow-up moments. In addition, the PROMs will also be sent to the patients at 3 and 6 months after surgery. The HOOS at 3-month follow-up will be our primary outcome. Ethics and dissemination This trial will be performed in accordance with the Declaration of Helsinki. A local ethics committee has approved this trial. Written informed consent will be obtained from all participating patients. All serious adverse events will be reported to the ethics committee. Results Results will be submitted for publication to an orthopaedics related journal. Trial registration number NTR1560. PMID:27009147

    Objective The Lebanese Multiple Sclerosis (LeMS) study aims to assess the influence of pregnancy and delivery on the clinical course of multiple sclerosis (MS) in Lebanese women. Setting This prospective multicentre study took place in three MS referral university medical centres in Lebanon. Participants Included were 29 women over 18 years who had been diagnosed with MS according to the McDonald criteria, and became pregnant between 1995 and 2015. Participating women should have stopped treatment 3 months before conception and become pregnant after the onset of MS. Women were followed up from 1 year preconceptionally and for 4 years postpartum. Main outcome measures The annualised relapse rates per participant during each 3-month period during pregnancy and each year postpartum were compared with the relapse rate during the year before pregnancy using the paired two-tailed t test. p Values <0.05 were considered statistically significant for all analyses (95% CI). Results 64 full-term pregnancies were recorded. All pregnancies (100%) resulted in live births, with no complications or other diseases. In comparison with the prepregnancy year, in which the mean relapse rate±SE was 0.17±0.07, there was a significant reduction in the relapse rate during pregnancy and in the first year postpartum (p=0.02), but an increase in the rate in the second year postpartum (0.21±0.08). Thereafter, from the third year postpartum through the following fourth year, the annualised relapse rate fell slightly but did not differ from the annualised relapse rate recorded in the prepregnancy year (0.17±0.07). Conclusions Pregnancy in Lebanese women with MS does not seem to increase the risk of complications. No relapses were observed during pregnancy and in the first year postpartum; however, relapses rebounded in the second year postpartum, and over the long term, returned to the levels that preceded pregnancy.

    Inverse associations of coffee and/or tea in relation to hepatocellular carcinoma (HCC) risk have been consistently identified in studies conducted mostly in Asia where consumption patterns of such beverages differ from Europe. In the European Prospective Investigation into Cancer and nutrition (EPIC), we identified 201 HCC cases among 486,799 men/women, after a median follow-up of 11 years. We calculated adjusted hazard ratios (HRs) for HCC incidence in relation to quintiles/categories of coffee/tea intakes. We found that increased coffee and tea intakes were consistently associated with lower HCC risk. The inverse associations were substantial, monotonic and statistically significant. Coffee consumers in the highest compared to the lowest quintile had lower HCC risk by 72% [HR: 0.28; 95% confidence intervals (CIs): 0.16-0.50, p-trend < 0.001]. The corresponding association of tea with HCC risk was 0.41 (95% CI: 0.22-0.78, p-trend = 0.003). There was no compelling evidence of heterogeneity of these associations across strata of important HCC risk factors, including hepatitis B or hepatitis C status (available in a nested case-control study). The inverse, monotonic associations of coffee intake with HCC were apparent for caffeinated (p-trend = 0.009), but not decaffeinated (p-trend = 0.45) coffee for which, however, data were available for a fraction of subjects. Results from this multicentre, European cohort study strengthen the existing evidence regarding the inverse association between coffee/tea and HCC risk. Given the apparent lack of heterogeneity of these associations by HCC risk factors and that coffee/tea are universal exposures, our results could have important implications for high HCC risk subjects.

    Mycophenolate mofetil (MMF) with prednisolone has been associated with high remission rates when used as induction treatment for lupus nephritis. This prospective, multicentre, cohort study investigates the efficacy and safety of this regimen over 24 weeks in 213 Chinese patients with active lupus nephritis (Classes III, IV, V or combination). Baseline activity index (AI) was 6.91+/-3.33 and chronicity index (CI) was 1.9+/-1.2. The remission rate was 82.6% at 24 weeks (complete remission, 34.3%; partial remission, 48.4%). There were significant (P<0.01) improvements in kidney function shown by reductions in proteinuria, serum albumin, serum creatinine and creatinine clearance, as well as in systemic lupus erythematosus disease activity index (SLEDAI) scores. Independent risk factors influencing remission were pathological classification (including Class V and III or Class V and IV nephritis) and elevated serum creatinine at baseline (OR 2.967, 95% CI: 1.479-6.332, P=0.001 and OR 1.007, 95% CI: 1.002-1.011, P=0.001, respectively). Patients with concomitant membranous features on biopsy had a lower remission rate than those with Class III and IV nephritis (66.7% vs 87.3%, P=0.002). Renal biopsy was repeated in 25 patients following treatment. There was a transition to less severe pathological morphologies in majority of subjects. Infections were monitored throughout treatment: eight patients (3.8%) experienced bacterial infections, whereas herpes zoster occurred in seven patients. Nine patients (4.2%) suffered from gastrointestinal upset, which resolved without discontinuation of MMF. One patient became leucopenic, whereas another died from active disease unrelated to kidney symptoms. MMF combined with prednisolone is an effective and well-tolerated induction treatment for patients with active lupus nephritis and for controlling SLE systemic activity. PMID:18625634

    Introduction. Febuxostat, a novel xanthine oxidase inhibitor for the treatment of symptomatic hyperuricemia, showed superiority over allopurinol in the reduction of serum uric acid levels in pivotal studies. Whether this holds true the FORTE (febuxostat in the oral urate lowering treatment: effectiveness and safety) study was conducted to evaluate treatment with febuxostat under daily practice conditions. Materials/Methods. The multicentre, open-label, and prospective observational study was conducted in 1,690 German medical practices from 9/2010 to 5/2011. Safety and efficacy data were assessed at baseline and week 4. Results. Data from 5,592 gout patients (72.6% male, mean age 63.7 years) were collected. Under urate lowering treatment with febuxostat mean serum uric acid levels decreased significantly from 8.9 ± 1.9 mg/dL (534.0 ± 114.6 μmol/L) at baseline to 6.2 ± 2.5 mg/dL (372.0 ± 150.0 μmol/L) at week 4. 67% which reached the mean uric acid target (6.1 ± 1.0 mg/dL [366.0 ± 59.4 μmol/L]). Only 43.1% of patients received concomitant flare prophylaxis. A total of 178 adverse events (mostly gout flares) were reported in 152 patients (2.6%). Conclusion. Febuxostat lowers serum uric acid levels effectively in routine clinical practice. Overall, treatment with febuxostat in both available dosages (80 mg/120 mg) was safe and well tolerated.

  20. Azithromycin for Indigenous children with bronchiectasis: study protocol for a multi-centre randomized controlled trial

    PubMed Central

    2012-01-01

    Background The prevalence of chronic suppurative lung disease (CSLD) and bronchiectasis unrelated to cystic fibrosis (CF) among Indigenous children in Australia, New Zealand and Alaska is very high. Antibiotics are a major component of treatment and are used both on a short or long-term basis. One aim of long-term or maintenance antibiotics is to reduce the frequency of acute pulmonary exacerbations and symptoms. However, there are few studies investigating the efficacy of long-term antibiotic use for CSLD and non-CF bronchiectasis among children. This study tests the hypothesis that azithromycin administered once a week as maintenance antibiotic treatment will reduce the rate of pulmonary exacerbations in Indigenous children with bronchiectasis. Methods/design We are conducting a multicentre, randomised, double-blind, placebo controlled clinical trial in Australia and New Zealand. Inclusion criteria are: Aboriginal, Torres Strait Islander, Maori or Pacific Island children aged 1 to 8 years, diagnosed with bronchiectasis (or probable bronchiectasis) with no underlying disease identified (such as CF or primary immunodeficiency), and having had at least one episode of pulmonary exacerbation in the last 12 months. After informed consent, children are randomised to receive either azithromycin (30 mg/kg once a week) or placebo (once a week) for 12–24 months from study entry. Primary outcomes are the rate of pulmonary exacerbations and time to pulmonary exacerbation determined by review of patient medical records. Secondary outcomes include length and severity of pulmonary exacerbation episodes, changes in growth, school loss, respiratory symptoms, forced expiratory volume in 1-second (FEV1; for children ≥6 years), and sputum characteristics. Safety endpoints include serious adverse events. Antibiotic resistance in respiratory bacterial pathogens colonising the nasopharynx is monitored.

    Background and Aims Healthcare professionals are required to conduct quality control of endoscopy procedures, and yet there is no standardised method for assessing quality. The topic of the present study was to validate the applicability of the procedure in daily practice, giving physicians the ability to define areas for continuous quality improvement. Methods In ten endoscopy units in France, 200 patients per centre undergoing colonoscopy were enrolled in the study. An evaluation was carried out based on a prospectively developed checklist of 10 quality-control indicators including five dependent upon and five independent of the colonoscopy procedure. Results Of the 2000 procedures, 30% were done at general hospitals, 20% at university hospitals, and 50% in private practices. The colonoscopies were carried out for a valid indication for 95.9% (range 92.5–100). Colon preparation was insufficient in 3.7% (range 1–10.5). Colonoscopies were successful in 95.3% (range 81–99). Adenoma detection rate was 0.31 (range 0.17–0.45) in successful colonoscopies. Conclusion This tool for evaluating the quality of colonoscopy procedures in healthcare units is based on standard endoscopy and patient criteria. It is an easy and feasible procedure giving the ability to detect suboptimal practice and differences between endoscopy-units. It will enable individual units to assess the quality of their colonoscopy techniques. PMID:22509267

    Background and Objectives LDL apheresis is used to treat patients with familial hypercholesterolaemia, and low-volume plasmapheresis for plasma donation may similarly lower cholesterol levels in some donors. This study was designed to assess the effect of plasmapheresis on total, LDL and HDL cholesterol levels in a plasma donor population. Materials and Methods This was a prospective, unblinded longitudinal cohort study in which a blood sample was obtained for analysis before each donation. Data from 663 donors were analysed using a multivariable repeated measures regression model with a general estimating equations approach with changes in cholesterol as the primary outcome measure. Results The model predicted a significant decrease in total and LDL cholesterol for both genders and all baseline cholesterol levels (P < 0·01). The greatest total cholesterol decreases (women, −46·8 mg/dL; men, −32·2 mg/dL) were associated with high baseline levels and 2–4 days between donations. Small but statistically significant increases (P ≤ 0·01) in HDL cholesterol were predicted for donors with low baseline levels. Conclusions These results suggest that, in donors with elevated baseline cholesterol levels, total and LDL cholesterol levels may decrease during routine voluntary plasmapheresis. PMID:23517282

    Objective This study aimed to evaluate the surgical treatment of acute pancreatitis in Italy and to assess compliance with international guidelines. Methods A series of 1173 patients in 56 hospitals were prospectively enrolled and their data analysed. Results Twenty-nine patients with severe pancreatitis underwent surgical intervention. Necrosectomy was performed in 26 patients, associated with postoperative lavage in 70% of cases. A feeding jejunostomy was added in 37% of cases. Mortality was 21%. Of the patients with mild pancreatitis, 714 patients with a biliary aetiology were evaluated. Prophylactic treatment of relapses was carried out in 212 patients (36%) by cholecystectomy and in 161 using a laparoscopic approach. Preoperative endoscopic retrograde cholangiopancreatography was associated with cholecystectomy in 83 patients (39%). Forty-seven patients (22%) were treated at a second admission, with a median delay of 31 days from the onset of pancreatitis. Eighteen patients with severe pancreatitis underwent cholecystectomy 37.9 days after the first admission. There were no deaths. Discussion The results indicate poor compliance with published guidelines. In severe pancreatitis, early surgical intervention is frequently performed and enteral feeding is seldom used. Only a small number of patients with mild biliary pancreatitis undergo definitive treatment (i.e. cholecystectomy) within 4 weeks of the onset of pancreatitis. PMID:20961367

    Background: Disturbance of the sleep–wake cycle is a characteristic of delirium. In addition, changes in melatonin rhythm influence the circadian rhythm and are associated with delirium. We compared the effect of melatonin and placebo on the incidence and duration of delirium. Methods: We performed this multicentre, double-blind, randomized controlled trial between November 2008 and May 2012 in 1 academic and 2 nonacademic hospitals. Patients aged 65 years or older who were scheduled for acute hip surgery were eligible for inclusion. Patients received melatonin 3 mg or placebo in the evening for 5 consecutive days, starting within 24 hours after admission. The primary outcome was incidence of delirium within 8 days of admission. We also monitored the duration of delirium. Results: A total of 452 patients were randomly assigned to the 2 study groups. We subsequently excluded 74 patients for whom the primary end point could not be measured or who had delirium before the second day of the study. After these postrandomization exclusions, data for 378 patients were included in the main analysis. The overall mean age was 84 years, 238 (63.0%) of the patients lived at home before admission, and 210 (55.6%) had cognitive impairment. We observed no effect of melatonin on the incidence of delirium: 55/186 (29.6%) in the melatonin group v. 49/192 (25.5%) in the placebo group; difference 4.1 (95% confidence interval −0.05 to 13.1) percentage points. There were no between-group differences in mortality or in cognitive or functional outcomes at 3-month follow-up. Interpretation: In this older population with hip fracture, treatment with melatonin did not reduce the incidence of delirium.

    Objective. The aim of this study was to determine whether biologic-free remission of RA is possible with discontinuation of abatacept. Methods. Japanese RA patients in 28-joint DAS with CRP (DAS28-CRP) remission (<2.3) after >2 years of abatacept treatment in a phase II study and its long-term extension entered this 52 week, multicentre, non-blinded, prospective, observational study. At enrolment, the patients were offered the option to continue abatacept or not. The primary endpoint was the proportion of patients who remained biologic-free at 52 weeks after discontinuation. Clinical, functional and structural outcomes were compared between those who continued and those who discontinued abatacept. Results. Of 51 patients enrolled, 34 discontinued and 17 continued abatacept treatment. After 52 weeks, 22 of the 34 patients (64.7%) remained biologic-free. Compared with the continuation group, the discontinuation group had a similar remission rate (41.2% vs 64.7%, P = 0.144) although they had a significantly higher mean DAS28-CRP score at week 52 (2.9 vs 2.0, P = 0.012). The two groups were also similar with regard to mean HAQ Disability Index (HAQ-DI) score (0.6 for both, P = 0.920), mean change in total Sharp score (ΔTSS; 0.80 vs 0.32, P = 0.374) and proportion of patients in radiographic remission (ΔTSS ≤ 0.5) at the endpoint (64.3% vs 70.6%, P = 0.752). Those attaining DAS28-CRP < 2.3 or < 2.7 without abatacept at the endpoint had significantly lower HAQ-DI score and/or CRP at enrolment. Non-serious adverse events occurred in three patients who continued or resumed abatacept. Conclusion. Biologic-free remission of RA is possible in some patients after attaining clinical remission with abatacept. Lower baseline HAQ-DI or CRP may predict maintenance of remission or low disease activity after discontinuation of abatacept.

    OBJECTIVE: A randomized controlled trial was conducted to determine whether 7 days of intravenous eflornithine (100 mg/kg every 6 h) was as effective as the standard 14-day regimen in the treatment of late-stage Trypanosoma brucei gambiense trypanosomiasis. METHODS: A total of 321 patients (274 new cases, 47 relapsing cases) were randomized at four participating centres in Congo, Côte d'Ivoire, the Democratic Republic of the Congo, and Uganda to one of these treatment regimens and followed up for 2 years. RESULTS: Six patients died during treatment, one of whom was on the 7-day regimen, whereas the other five had been on the 14-day regimen (P = 0.2). The response to eflornithine differed markedly between Uganda and other countries. Among new cases in Uganda, the 2-year probability of cure was 73% on the 14-day course compared with 62% on the 7-day regimen (hazard ratio (HR) for treatment failure, 7-day versus 14-day regimen: 1.45, 95% CI: 0.7, 3.1, P = 0.3). Among new cases in Côte d'Ivoire, Congo, and the Democratic Republic of the Congo combined, the 2-year probability of cure was 97% on the 14-day course compared with 86.5% on the 7-day regimen (HR for treatment failure, 7-day vs 14-day: 6.72, 95% confidence interval (CI): 1.5, 31.0, P = 0.003). Among relapsing cases in all four countries, the 2-year probability of cure was 94% with 7 days and 100% with 14 days of treatment. Factors associated with a higher risk of treatment failure were: a positive lymph node aspirate (HR 4.1; 95% CI: 1.8-9.4), a cerebrospinal fluid (CSF) white cell count > or = 100/mm3 (HR 3.5; 95% CI: 1.1-10.9), being treated in Uganda (HR 2.9; 95% CI: 1.4-5.9), and CSF trypanosomes (HR 1.9; 95% CI: 0.9-4.1). Being stuporous on admission was associated with a lower risk of treatment failure (HR 0.18; 95% CI: 0.02-1.4) as was increasing age (HR 0.977; 95% CI: 0.95-1.0, for each additional year of age). DISCUSSION: The 7-day course of eflornithine is an effective treatment of relapsing cases

    Objective Elective minilaparotomy abdominal aortic aneurysm (AAA) repair is associated with a significant number of complications involving respiratory, cardiovascular, gastrointestinal, and central nervous systems, with mortality ranging up to 5%. In our study, we tested the hypothesis that intra- and postoperative intravenous restrictive fluid regimen reduces postoperative morbidity and mortality, and improves the outcome of minilaparotomy AAA repair. Methods From March 2009 to July 2013, 60 patients operated due to AAA were included in a prospective randomized controlled trial (RCT). About the administration of fluid during the operation and in the early postoperative period, all the patients were randomized into two groups: the group of standard fluid administration (S-group, 30 patients) and the group of reduced fluid administration (R-group, 30 patients). The verification of the treatment success was measured by the length of intensive care unit (ICU) stay, duration of hospitalization after the procedure, as well as the number and type of postoperative complications and mortality. This prospective RCT was registered in a publicly accessible database ClinicalTrials.gov with unique Identifier ID: NTC01939652. Results Total fluid administration and administration of blood products were significantly lower in R-group as compared with S-group (2,445.5 mL vs. 3308.7 mL, p = 0.004). Though the number of nonlethal complications was significantly lower in R-group (2 vs. 9 patients, p = 0.042), the difference in lethal complications remained nonsignificant (0 vs. 1 patient, p = ns). The average ICU stay (1.2 vs. 1.97 days, p = 0.003) and duration of postoperative hospital stay (4.33 vs. 6.20 days, p = 0.035 for R-group and S-group, respectively) were found to be significantly shorter in R-group. Conclusion Intra- and postoperative restrictive intravenous fluid regimen in patients undergoing minilaparotomy AAA repair significantly reduces

    Hyaloglide is a hyaluronan-based gel based on a novel auto-crosslinked technology designed to reduce postsurgical adhesions. Its efficacy was assessed in a multicentred randomized controlled trial comparing the results of flexor tenolysis in zone 2 following failed flexor tendon repairs. In the control group a standard release was performed. In the treated group, Hyaloglide was applied into the flexor sheath and around the site of tenolysis. Forty-five patients, 19 controls and 26 treated with Hyaloglide, were enrolled in 13 centres. All the patients were evaluated at 30, 60, 90 and 180 days after surgery by testing Total Active Motion, Quick-DASH questionnaire and number of working days lost after surgery. Patients in the Hyaloglide group had a statistically better recovery of finger motion at all time intervals and returned earlier to work and daily activities. The use of Hyaloglide did not appear to increase the complication rate. PMID:19710086

    Objective: To evaluate the efficacy of suprascapular nerve block in combination with infusion of anesthetic into the subacromial space, compared with interscalene block. Methods: Forty-five patients with small or medium-sized isolated supraspinatus tendon lesions who underwent arthroscopic repair were prospectively and comparatively evaluated through random assignation to three groups of 15, each with a different combination of anesthetic methods. The efficacy of postoperative analgesia was measured using the visual analogue scale for pain and the analgesic, anti-inflammatory and opioid drug consumption. Inhalation anesthetic consumption during surgery was also compared between the groups. Results: The statistical analysis did not find any statistically significant differences among the groups regarding anesthetic consumption during surgery or postoperative analgesic efficacy during the first 48 hours. Conclusion: Suprascapular nerve block with infusion of anesthetic into the subacromial space is an excellent alternative to interscalene block, particularly in hospitals in which an electrical nerve stimulating device is unavailable.

    Background. Icodextrin is a glucose polymer derived by hydrolysis of cornstarch. The different biocompatibility profile of icodextrin-containing peritoneal dialysis (PD) solutions may have a positive influence on peritoneal host defence. Furthermore, cases of sterile peritonitis potentially associated with icodextrin have been reported. Methods. The primary objective of this multicentre, longitudinal, observational, non-interventional, prospective cohort study, which included 722 PD patients, was to evaluate the incidence of overall peritonitis in patients treated with icodextrin-containing PD solutions (Extraneal™) used during one long-dwell exchange/day compared with those treated with non-icodextrin-containing PD solutions. The secondary objective was to determine if culture-negative peritonitis rates differed between patients treated with icodextrin from two independent manufacturers. All peritonitis episodes were assessed by a Steering Committee in a blind manner. Results. There was no significant difference between icodextrin-treated and control patients in the adjusted overall, culture-positive or culture-negative peritonitis rates. When stratified by the icodextrin supplier, there was no significant difference in the adjusted rate of culture-negative peritonitis episodes between groups. Conclusion. Subjects receiving icodextrin as part of their PD regimen experienced neither a higher rate of culture-negative peritonitis nor a lower rate of infectious peritonitis compared with non-icodextrin users. There was no significant influence of the icodextrin raw material supplier on peritonitis rates. PMID:18556747

    The purpose of this prospective multicentric observational study was to confirm the safety and clinical performance of a craniocaudal expandable implant used in combination with high viscosity PMMA bone cement for the treatment of vertebral compression fractures. Thirty-nine VCFs in 32 patients were treated using the SpineJack minimally invasive surgery protocol. Outcome was determined by using the Visual Analogue Scale for measuring pain, the Oswestry Disability Index for scoring functional capacity, and the self-reporting European Quality of Life scores for the quality of life. Safety was evaluated by reporting all adverse events. The occurrence of cement leakages was assessed by either radiographs or CT scan or both. Statistically significant improvements were found regarding pain, function, and quality of life. The global pain score reduction at 1 year was 80.9% compared to the preoperative situation and the result of the Oswestry Disability Index showed a decrease from 65.0% at baseline to 10.5% at 12 months postoperatively. The cement leakage rate was 30.8%. No device- or surgery-related complications were found. This observational study demonstrates promising and persistent results consisting of immediate and sustained pain relief and durable clinical improvement after the procedure and throughout the 1-year follow-up period.

    This prospective, consecutive, multicentre observational registry aimed to confirm the safety and clinical performance of the SpineJack system for the treatment of vertebral compression fractures (VCF) of traumatic origin. We enrolled 103 patients (median age: 61.6 years) with 108 VCF due to trauma, or traumatic VCF with associated osteoporosis. Primary outcome was back pain intensity (VAS). Secondary outcomes were Oswestry Disability Index (ODI), EuroQol-VAS, and analgesic consumption. 48 hours after surgery, a median relative decrease in pain intensity of 81.5% was observed associated with a significant reduction in analgesic intake. Improvements in disability (91.3% decrease in ODI score) and in quality of life (increase 21.1% of EQ-VAS score) were obtained 3 months after surgery. All results were maintained at 12 months. A reduction in the kyphotic angulation was observed postoperatively (−5.4 ± 6.3°; p < 0.001), remained at 12 months (−4.4 ± 6.0°, p = 0.002). No adverse events were implant-related and none required device removal. Three patients (2.9%) experienced procedure-related complications. The overall adjacent fracture rate up to 1 year after surgery was 2.9%. The SpineJack procedure is an effective, low-risk procedure for patients with traumatic VCF allowing a fast and sustained improvement in quality of life over 1 year after surgery. PMID:26844224

    Fever is a common symptom in children and one of the major concerns of parents of younger and preschool-age children. To compare the efficacy and safety of ketoprofen with that of paracetamol (acetaminophen) and ibuprofen in the treatment of febrile conditions in children. Two prospective, randomized, double-blind, double-dummy, repeated-dose, multicentre, phase III studies with two parallel groups in each study were conducted in primary-care outpatient clinics. Children aged 6 months to 6 years presenting with a febrile condition and an oral body temperature of > or =38.8 degrees C or rectal temperature of > or =39 degrees C were eligible for inclusion. Patients were randomized to receive either ketoprofen syrup 0.5 mg/kg, ibuprofen suspension 5 mg/kg or paracetamol suspension 15 mg/kg every 6 hours by the oral route. The primary outcome measure was the change in temperature at 3 hours (H3), compared with baseline (H0). All three treatments provided similar mean maximum decreases of 1.4-1.5 degrees C in body temperature at H3 compared with H0. Use of ketoprofen was not associated with any increased risk of adverse events compared with the two reference compounds. Ketoprofen 0.5 mg/kg appeared to be equivalent to the standard antipyretic doses of the reference products ibuprofen 5 mg/kg and paracetamol 15 mg/kg. Ketoprofen at the 0.5 mg/kg dose should be an effective and safe option for symptomatic management of fever in children. PMID:20380479

    Introduction Cholecystectomy is one of the most common general surgical operations performed. Despite level one evidence supporting the role of cholecystectomy in the management of specific gallbladder diseases, practice varies between surgeons and hospitals. It is unknown whether these variations account for the differences in surgical outcomes seen in population-level retrospective data sets. This study aims to investigate surgical outcomes following acute, elective and delayed cholecystectomies in a multicentre, contemporary, prospective, population-based cohort. Methods and analysis UK and Irish hospitals performing cholecystectomies will be recruited utilising trainee-led research collaboratives. Two months of consecutive, adult patient data will be included. The primary outcome measure of all-cause 30-day readmission rate will be used in this study. Thirty-day complication rates, bile leak rate, common bile duct injury, conversion to open surgery, duration of surgery and length of stay will be measured as secondary outcomes. Prospective data on over 8000 procedures is anticipated. Individual hospitals will be surveyed to determine local policies and service provision. Variations in outcomes will be investigated using regression modelling to adjust for confounders. Ethics and dissemination Research ethics approval is not required for this study and has been confirmed by the online National Research Ethics Service (NRES) decision tool. This novel study will investigate how hospital-level surgical provision can affect patient outcomes, using a cross-sectional methodology. The results are essential to inform commissioning groups and implement changes within the National Health Service (NHS). Dissemination of the study protocol is primarily through the trainee-led research collaboratives and the Association of Upper Gastrointestinal Surgeons (AUGIS). Individual centres will have access to their own results and the collective results of the study will be published

    Inhibition of the mechanistic target of rapamycin (mTOR) pathway has clinical activity in lymphoma. The mTOR inhibitor sirolimus has been used in the prevention and treatment of graft-versus-host disease (GVHD) after allogeneic haematopoietic stem cell transplantation (HSCT). A retrospective study suggested that patients with lymphoma undergoing reduced intensity conditioning (RIC) HSCT who received sirolimus as part of their GVHD prophylaxis regimen had a lower rate of relapse. We therefore performed a multicentre randomized trial comparing tacrolimus, sirolimus and methotrexate to standard regimens in adult patients undergoing RIC HSCT for lymphoma in order to assess the possible benefit of sirolimus on HSCT outcome. 139 patients were randomized. There was no difference overall in 2-year overall survival, progression-free survival, relapse, non-relapse mortality or chronic GVHD. However, the sirolimus-containing arm had a significantly lower incidence of grade II-IV acute GVHD (9% vs. 25%, P = 0·015), which was more marked for unrelated donor grafts. In conclusion, the addition of sirolimus for GVHD prophylaxis in RIC HSCT is associated with no increased overall toxicity and a lower risk of acute GVHD, although it does not improve survival; this regimen is an acceptable option for GVHD prevention in RIC HSCT. This trial is registered at clinicaltrials.gov (NCT00928018). PMID:26729448

    Background: Total knee arthroplasty can be considered as a reliable surgical procedure with a good long-term clinical result. However, implant failure due to particle induced aseptic loosening as well as the aspect of hypersensitivity to metal ions still remains an emerging issue. Methods: The purpose of this prospective international multi-centre study was to evaluate the clinical and radiological outcomes and the reliability of the unconstrained Multigen Plus Total Knee System with a new BIOLOX® delta ceramic femoral component. Cemented total knee arthroplasty was performed on 108 patients (110 knees) at seven hospitals in three countries. Clinical and radiological evaluations were performed preoperatively, and after 3, 12 and 24 months postoperatively using the HSS-, WOMAC-, SF-36-score and standardised X-rays. Results: The mean preoperative HSS-Score amounted to 55.5 ± 11.5 points and improved significantly in all postoperative evaluations (85.7 ± 11.7 points at 24 months). Furthermore, improvements in WOMAC- and SF-36-score were evaluated as significant at all points of evaluation. Radiolucent lines around the femoral ceramic component at 24 months were found in four cases. Progression of radiolucent lines was not seen and no implant loosening was observed. During the 24 month follow-up eight patients underwent subsequent surgery due to reasons unrelated to the implant material. Conclusions: The observed clinical and radiological results are encouraging for a long-term survival of the ceramic femoral component. Therefore, ceramic implants could be a promising solution not only for patients with allergies against metallic implant materials, but also for the osteoarthritic knee joint. Long-term follow-up is necessary to draw conclusions regarding the superiority of the ceramic knee implants concerning in vivo wear and long-term survivorship. PMID:22582104

    Introduction Preoperative functional capacity is considered an important risk factor for cardiovascular and other complications of major non-cardiac surgery. Nonetheless, the usual approach for estimating preoperative functional capacity, namely doctors’ subjective assessment, may not accurately predict postoperative morbidity or mortality. 3 possible alternatives are cardiopulmonary exercise testing; the Duke Activity Status Index, a standardised questionnaire for estimating functional capacity; and the serum concentration of N-terminal pro-B-type natriuretic peptide (NT pro-BNP), a biomarker for heart failure and cardiac ischaemia. Methods and analysis The Measurement of Exercise Tolerance before Surgery (METS) Study is a multicentre prospective cohort study of patients undergoing major elective non-cardiac surgery at 25 participating study sites in Australia, Canada, New Zealand and the UK. We aim to recruit 1723 participants. Prior to surgery, participants undergo symptom-limited cardiopulmonary exercise testing on a cycle ergometer, complete the Duke Activity Status Index questionnaire, undergo blood sampling to measure serum NT pro-BNP concentration and have their functional capacity subjectively assessed by their responsible doctors. Participants are followed for 1 year after surgery to assess vital status, postoperative complications and general health utilities. The primary outcome is all-cause death or non-fatal myocardial infarction within 30 days after surgery, and the secondary outcome is all-cause death within 1 year after surgery. Both receiver-operating-characteristic curve methods and risk reclassification table methods will be used to compare the prognostic accuracy of preoperative subjective assessment, peak oxygen consumption during cardiopulmonary exercise testing, Duke Activity Status Index scores and serum NT pro-BNP concentration. Ethics and dissemination The METS Study has received research ethics board approval at all sites

    We characterized antibiotic resistance and virulence of uropathogenic Escherichia coli (UPEC) strains isolated from urinary tract infections (UTIs) in patients hospitalized in urology departments. A prospective multicentre study was initiated from March 2009 and lasted until February 2010 in French urology units. All patients with asymptomatic bacteriuria (ABU), acute cystitis, acute pyelonephritis or acute prostatitis in whom UPEC was detected were included. Antimicrobial resistance and virulence factors were compared among the different groups. To identify independent associations between virulence markers and the risk of UTI, we used a multivariate logistic regression. We included 210 patients (mean age: 65.8 years; 106 female). Episode of UTI was community acquired in 72.4 %. ABU was diagnosed in 67 cases (31.9 %), cystitis in 52 cases (24.7 %), pyelonephritis in 35 cases (16.7 %) and prostatitis in 56 cases (26.7 %). ABU was more frequent in patients with a urinary catheter (76.1 vs 23.9 %, P<0.001). The resistance rate was 7.6 and 24.8 % for cefotaxime and ciprofloxacin, respectively. UPEC isolated from infections belonged more frequently to phylotypes B2 and D (P =0.07). The papG allele II and papA, papC, papE, kpsMTII and iutA genes were significantly more frequent in infecting strains (P<0.05). In multivariate analysis, strains susceptible to ciprofloxacin were significantly associated with papG allele II (P=0.007), kpsMTK1 (P<0.001) and hlyA (P<0.001) compared with the ciprofloxacin-resistant strains. To the best of our knowledge, this is the first study evaluating the antibiotic resistance and virulence features of UPEC isolated from patients hospitalized in urology departments. High resistance rates were observed, notably for ciprofloxacin, highlighting the importance of a reinforced surveillance in this setting. PMID:26953145

    Background This was a prospective study of radiofrequency segmental thermal ablation (RFA) for the treatment of incompetent varicose great saphenous veins (GSVs). The present report describes long-term follow-up at 5 years. Methods The 5-year follow-up of this multicentre European study included assessment of the Venous Clinical Severity Score (VCSS), and GSV occlusion and reflux on duplex imaging. Results A total of 225 patients had 295 GSVs treated by RFA, achieving an initial vein occlusion rate of 100 per cent. With 80·0 per cent compliance, Kaplan–Meier analyses showed a GSV occlusion rate of 91·9 per cent and a reflux-free rate of 94·9 per cent at 5 years. Among the 15 GSVs noted with reflux during follow-up, only three showed full recanalization of the GSV at 1 week, 6 months and 3 years. Of the 12 legs with partial recanalization, reflux originated at the saphenofemoral junction in ten, with a mean length of the patent segment of 5·8 (range 3·2–10) cm; only six patients were symptomatic. Mean(s.d.) VCSS scores improved from 3·9(2·1) at baseline to 0·6(1·2), 0·9(1·3) and 1·3(1·7) at 1, 3 and 5 years. Conclusion At 5 years RFA proved to be an efficient endovenous treatment for incompetent GSVs in terms of sustained clinical and anatomical success for the vast majority of treated patients.

    Introduction A study has been developed to assess the use and effectiveness of budesonide MMX for mild-to-moderate active ulcerative colitis (UC) in routine clinical practice. Methods and analysis A prospective, multicentre, observational, cohort study of 300 patients prescribed budesonide MMX for the treatment of mild-to-moderate active UC will be conducted in Europe, Israel and Canada. Patients will be treated with budesonide MMX9 mg daily for induction of remission for ≤8 weeks. Data on effectiveness, including patient-reported outcomes, tolerability and use will be recorded at the end of treatment and at ≥2 weeks after. The primary outcome (improvement ≥3 point in the clinical subscores of the UC Disease Activity Index score at the end of treatment) will be compared in: patients who receive budesonide MMX added to mesalazine >2 weeks after increased/optimised mesalazine dose for the treatment of flare (late add-on); patients who receive budesonide MMX added to mesalazine ≤2 weeks since mesalazine increased/optimised for the treatment of flare, or without mesalazine dose modification (early add-on); and patients who receive budesonide MMX as monotherapy for the treatment of flare (mono). Propensity scoring will be used to minimise bias and confounding inherent in observational studies. Ethics and dissemination First ethical approval: Ethikkommission der Ärztekammer Hamburg (12/22/2015). The results will be published in full. Discussion Completion of primary data collection is expected in December 2017. Our results will provide further evidence on the effectiveness of budesonide MMX to support clinicians in their daily practice and inform therapeutic guidelines.

    PubMed Central

    2010-01-01

    Background Acute pharyngitis is one of the most frequent consultations to the general practitioner and in most of the cases an antibiotic is prescribed in primary care in Spain. Bacterial etiology, mainly by group A beta-hemolytic streptococcus (GABHS), accounts for 10-20% of all these infections in adults. The purpose of this study is to assess the impact of rapid antigen detection testing (RADT) to identify GABHS in acute pharyngitis on the utilization of antibiotics in primary care. Methods/design Multicentric randomized controlled trial in which antibiotic prescription between two groups of patients with acute pharyngitis will be compared. The trial will include two arms, a control and an intervention group in which RADT will be performed. The primary outcome measure will be the proportion of inappropriate antibiotic prescription in each group. Two hundred seventy-six patients are required to detect a reduction in antibiotic prescription from 85% in the control group to 75% in the intervention group with a power of 90% and a level of significance of 5%. Secondary outcome measures will be specific antibiotic treatment, antibiotic resistance rates, secondary effects, days without working, medical visits during the first month and patient satisfaction. Discussion The implementation of RADT would allow a more rational use of antibiotics and would prevent adverse effects of antibiotics, emergence of antibiotic resistance and the growth of inefficient health expenses.

    Aim. To compare the efficacy and safety of armodafinil, the R-enantiomer of modafinil, with modafinil in patients of shift work sleep disorder (SWSD). Material and Methods. This was a 12-week, randomized, comparative, double-blind, multicentric, parallel-group study in 211 patients of SWSD, receiving armodafinil (150 mg) or modafinil (200 mg) one hour prior to the night shift. Outcome Measures. Efficacy was assessed by change in stanford sleepiness score (SSS) by at least 2 grades (responder) and global assessment for efficacy. Safety was assessed by incidence of adverse events, change in laboratory parameters, ECG, and global assessment of tolerability. Results. Both modafinil and armodafinil significantly improved sleepiness mean grades as compared to baseline (P < .0001). Responder rates with armodafinil (72.12%) and modafinil (74.29%) were comparable (P = .76). Adverse event incidences were comparable. Conclusion. Armodafinil was found to be safe and effective in the treatment of SWSD in Indian patients. The study did not demonstrate any difference in efficacy and safety of armodafinil 150 mg and modafinil 200 mg. PMID:21766023

    Summary Background Even though progress has been made, the detection of melanoma still poses a challenge. In light of this situation, the Nevisense electrical impedance spectroscopy (EIS) system (SciBase AB, Stockholm, Sweden) was designed and shown to have the potential to be used as an adjunct diagnostic tool for melanoma detection. Objectives To assess the effectiveness and safety of the Nevisense system in the distinction of benign lesions of the skin from melanoma with electrical impedance spectroscopy. Methods This multicentre, prospective, and blinded clinical study was conducted at five American and 17 European investigational sites. All eligible skin lesions in the study were examined with the EIS-based Nevisense system, photographed, removed by excisional biopsy and subjected to histopathological evaluation. A postprocedure clinical follow-up was conducted at 7 ± 3 days from the initial measurement. A total of 1951 patients with 2416 lesions were enrolled into the study; 1943 lesions were eligible and evaluable for the primary efficacy end point, including 265 melanomas – 112 in situ and 153 invasive melanomas with a median Breslow thickness of 0·57 mm [48 basal cell carcinomas (BCCs) and seven squamous cell carcinomas (SCCs)]. Results The observed sensitivity of Nevisense was 96·6% (256 of 265 melanomas) with an exact one-sided 95% lower confidence bound estimated at 94·2% and an observed specificity of 34·4%, and an exact two-sided 95% confidence bound estimated at 32·0–36·9%. The positive and negative predictive values of Nevisense were 21·1% and 98·2%, respectively. The observed sensitivity for nonmelanoma skin cancer was 100% (55 of 48 BCCs and seven SCCs) with an exact two-sided 95% confidence bound estimated at 93·5–100·0%. Conclusions Nevisense is an accurate and safe device to support clinicians in the detection of cutaneous melanoma. What's already known about this topic?

    Continuous interscalene brachial plexus block has been shown to be the most effective analgesic technique following shoulder surgery; however, its use is uncommon due to logistical and safety concerns related to ambulatory administration. We prospectively studied 1505 consecutive patients undergoing shoulder surgery who received continuous interscalene analgesia at home. Catheter removal was by the patient between postoperative days two and five. There were no major complications although 27% of patients reported mild dyspnoea, 13% hoarseness and 7% dysphagia. Twelve percent sought medical advice and 2% reported technical issues with the pump or tubing. Complications and technical issues were associated with patient age; weight; use of ultrasound or concomitant nerve stimulation as the endpoint for final needle tip position; local anaesthetic placement via the catheter or needle; whether a catheter-related intervention for pain relief was required in the recovery area; and the type of ambulatory pump. We conclude that this study supports the safety of this underused analgesic technique. PMID:26849172

    Genital herpes simplex virus (HSV) infection, a sexually transmitted disease (STD), is the commonest cause of ulcerative genital infections among the young and adult population. The significant association of genital ulceration and transmission of human immunodeficiency virus (HIV) has been shown in many studies. To explore the potential efficacy of topical treatment of genital herpes with penciclovir cream, a randomized, double-blind, multicentre, acyclovir-controlled Phase II clinical trial of penciclovir 1% cream 5 times daily up to 7 days for suppression of genital herpes was conducted in China. A total of 205 patients aged 20-59 years (mean age 36.0+/-8.8 years for acyclovir and 34.8+/-8.4 years for penciclovir) with a clinical diagnosis of genital herpes were randomly allocated to one of the 2 parallel treatment groups and used for analysis. Clinical assessment were made before treatment and followed up at every visit during the study. Our results show that there was an encouraging improvement simultaneously in the 2 groups although no significant differences in clinical efficacy with respect to clinical cure rate, and times to healing, resolution of all symptoms, absence of blisters, cessation of new blisters, crusting, and loss of crust between penciclovir and acyclovir groups in terms of primary, non-primary and total patients were found. However a significantly shorter time to crusting was found in primary penciclovir group when compared with primary acyclovir group. Adverse experience was generally infrequent and mild, and was comparable in the 2 treatment groups. Based on these preliminary clinical findings, further evaluation of penciclovir 3% cream for topical treatment of genital herpes is planned. PMID:10997497

    Background: Conventional topical tretinoin formulation is often associated with local adverse events. Nanogel formulation of tretinoin has good physical stability and enables good penetration of tretinoin into the pilo-sebaceous glands. Aim: The present study was conducted to assess the efficacy and safety of a nanogel formulation of tretinoin as compared to its conventional gel formulation in the treatment of acne vulgaris of the face. Materials and Methods: This randomized, active controlled, multicentric, phase IV clinical trial evaluated the treatment of patients with acne vulgaris of the face by the two gel formulations locally applied once daily at night for 12 wk. Acne lesion counts (inflammatory, non-inflammatory & total) and severity grading were carried out on the monthly scheduled visits along with the tolerability assessments. Results: A total of 207 patients were randomized in the study. Reductions in the total (72.9% vs. 65.0%; p = 0.03) and inflammatory (78.1% vs. 66.9%; p = 0.02) acne lesions were reported to be significantly greater with the nanogel formulation as compared to the conventional gel formulation. Local adverse events were significantly less (p = 0.04) in the nanogel group (13.3%) as compared to the conventional gel group (24.7%). Dryness was the most common adverse event reported in both the treatment groups while peeling of skin, burning sensation and photosensitivity were reported in patients using the conventional gel only. Conclusion: In the treatment of acne vulgaris of the face, tretinoin nanogel formulation appears to be more effective and better tolerated than the conventional gel formulation. PMID:25738069

    Fifty-five patients with psoriatic arthritis were treated with a low dose of cyclosporin A (CyA) (mean dose 2.7 mg/kg per day) for a period of 6 months to investigate the efficacy of CyA on disease parameters. Significant improvement in the joint complaints and inflammation parameters was observed including a decrease in the number of painful (-46%) and swollen (-45%) joints, tenderness (Ritchie Index: -50%) and degree of swelling (-46%), patient's assessment of pain (-35%), the duration of morning joint stiffness (-37%), as well as a decrease in C-reactive protein (-52%). A 50% reduction of joint complaints required a total of 24 weeks, whereas a 50% reduction of skin involvement was achieved after 5-6 weeks of treatment. Four patients left the study due to adverse events: creatinine level increase in two patients, hypertension in one patient and gastroenteritis in the fourth patient. Joint scintigraphy in 18 patients indicated an improvement or stable condition in 61% of cases after a mean follow-up of approximately 8 months. The results of this prospective study show that low-dose CyA effectively improves not only skin lesions, but also joint complaints in psoriatic arthritis. PMID:8977676

    Increasing antibiotic resistance makes choosing antibiotics for suspected Gram-negative infection challenging. This study set out to identify key determinants of mortality among patients with Gram-negative bacteraemia, focusing particularly on the importance of appropriate empiric antibiotic treatment. We conducted a prospective observational study of 679 unselected adults with Gram-negative bacteraemia at ten acute english hospitals between October 2013 and March 2014. Appropriate empiric antibiotic treatment was defined as intravenous treatment on the day of blood culture collection with an antibiotic to which the cultured organism was sensitive in vitro. Mortality analyses were adjusted for patient demographics, co-morbidities and illness severity. The majority of bacteraemias were community-onset (70%); most were caused by Escherichia coli (65%), Klebsiella spp. (15%) or Pseudomonas spp. (7%). Main foci of infection were urinary tract (51%), abdomen/biliary tract (20%) and lower respiratory tract (14%). The main antibiotics used were co-amoxiclav (32%) and piperacillin-tazobactam (30%) with 34% receiving combination therapy (predominantly aminoglycosides). Empiric treatment was inappropriate in 34%. All-cause mortality was 8% at 7 days and 15% at 30 days. Independent predictors of mortality (p <0.05) included older age, greater burden of co-morbid disease, severity of illness at presentation and inflammatory response. Inappropriate empiric antibiotic therapy was not associated with mortality at either time-point (adjusted OR 0.82; 95% CI 0.35-1.94 and adjusted OR 0.92; 95% CI 0.50-1.66, respectively). Although our study does not exclude an impact of empiric antibiotic choice on survival in Gram-negative bacteraemia, outcome is determined primarily by patient and disease factors. PMID:26577143

    Introduction Tuberculosis disease (TB) remains an important global health threat. An evidence-based response, tailored to local disease epidemiology in high-burden countries, is key to controlling the global TB epidemic. Reliable surrogate biomarkers that predict key active disease and latent TB infection outcomes are vital to advancing clinical research necessary to ‘End TB’. Well executed longitudinal studies strengthening local research capacity for addressing TB research priorities and advancing biomarker discovery are urgently needed. Methods and analysis The Cohort for Tuberculosis Research by the Indo-US Medical Partnership (CTRIUMPH) study conducted in Byramjee Jeejeebhoy Government Medical College (BJGMC), Pune and National Institute for Research in Tuberculosis (NIRT), Chennai, India, will establish and maintain three prospective cohorts: (1) an Active TB Cohort comprising 800 adults with pulmonary TB, 200 adults with extrapulmonary TB and 200 children with TB; (2) a Household Contact Cohort of 3200 adults and children at risk of developing active disease; and (3) a Control Cohort consisting of 300 adults and 200 children with no known exposure to TB. Relevant clinical, sociodemographic and psychosocial data will be collected and a strategic specimen repository established at multiple time points over 24 months of follow-up to measure host and microbial factors associated with (1) TB treatment outcomes; (2) progression from infection to active TB disease; and (3) Mycobacterium tuberculosis transmission among Indian adults and children. We anticipate CTRIUMPH to serve as a research platform necessary to characterise some relevant aspects of the TB epidemic in India, generate evidence to inform local and global TB control strategies and support novel TB biomarker discovery. Ethics and dissemination This study is approved by the Institutional Review Boards of NIRT, BJGMC and Johns Hopkins University, USA. Study results will be disseminated through peer

    2014-01-01

    Background Most of Multiple Sclerosis (MS) patients undergo disease modifying drug (DMD) therapy at childbearing age. The objective of this prospective, collaborative study, was to assess outcomes of pregnancies fathered by MS patients undergoing DMD. Methods Structured interviews on pregnancies fathered by MS patients gathered in the Italian Pregnancy Dataset were collected; pregnancies were divided according to father exposure or unexposure to DMD at time of procreation. Treatment were compared with multivariable logistic and linear models. Results Seventy-eight pregnancies fathered by MS patients were tracked. Forty-five patients were taking DMD at time of conception (39 beta-interferons, 6 glatiramer acetate), while 33 pregnancies were unexposed to DMD. Seventy-five pregnancies ended in live-births, 44 in the exposed and 31 in the unexposed group. No significant differences between the two groups were found in the risk of spontaneous abortion or malformations (p > 0.454), mean gestational age (p = 0.513), frequency of cesarean delivery (p = 0.644), birth weight (p = 0.821) and birth length (p = 0.649). In comparison with data of the Italian general population, the proportion of spontaneous abortion and caesarean delivery in exposed pregnancies fell within the estimates, while the proportion of pre-term delivery in the exposed group was higher than expected. Conclusions Our data indicate no association between paternal DMD exposure at time of conception and risk of spontaneous abortion, adverse fetal outcomes and congenital malformations. Further studies clarifying the role of DMD fathers intake prior and during pregnancy are desirable, to supply guidelines for clinical practice. PMID:24884599

    Background The use of artemisinin derivative-based combination therapy (ACT) such as artesunate plus amodiaquine is currently recommended for the treatment of uncomplicated Plasmodium falciparum malaria. Fixed-dose combinations are more adapted to patients than regimens involving multiple tablets and improve treatment compliance. A fixed-dose combination of artesunate + amodiaquine (ASAQ) was recently developed. To assess the efficacy and safety of this new combination and to define its optimum dosage regimen (once or twice daily) in the treatment of uncomplicated P. falciparum malaria, a multicentre clinical study was conducted. Methods A multicentre, randomized, controlled, investigator-blinded, parallel-group study was conducted in five African centers in Cameroon, Madagascar, Mali and Senegal from March to December 2006. Efficacy and safety of ASAQ were assessed compared to those of artemether + lumefantrine (AL). The WHO protocol with a 28-day follow-up for assessing the drug therapeutic efficacy was used. Patients suffering from uncomplicated P. falciparum malaria were randomized to receive ASAQ orally once daily (ASAQ1), ASAQ twice daily (ASAQ2) or AL twice daily (AL) for three days. The primary outcome was PCR-corrected parasitological cure rate and clinical response. Results Of 941 patients initially randomized and stratified into two age groups (<5 years, and ≥5 years), 936 (99.5%) were retained for the intent to treat (ITT) analysis, and 859 (91.3%) patients for the per protocol (PP) analysis. Among ITT population, up to D28, PCR-corrected adequate parasitological and clinical response rates were 95.2% in the ASAQ1 group, 94.9% in the ASAQ2 group and 95.5% in the AL group. Moreover, the cure rate evaluated among PP population was ≥98.5% in both ASAQ therapeutic arms. Therapeutic response rates did not display any significant differences between age groups or between one geographical site and another. Altogether, this demonstrates the non

    Background To describe the causes of graft loss, patient death and survival figures in kidney transplant patients in Spain based on the recipient's age. Methods The results at 5 years of post-transplant cardiovascular disease (CVD) patients, taken from a database on CVD, were prospectively analysed, i.e. a total of 2600 transplanted patients during 2000–2002 in 14 Spanish renal transplant units, most of them receiving their organ from cadaver donors. Patients were grouped according to the recipient's age: Group A: <40 years, Group B: 40–60 years and Group C: >60 years. The most frequent immunosuppressive regimen included tacrolimus, mycophenolate mofetil and steroids. Results Patients were distributed as follows: 25.85% in Group A (>40 years), 50.9% in Group B (40–60 years) and 23.19% in Group C (>60). The 5-year survival for the different age groups was 97.4, 90.8 and 77.7%, respectively. Death-censored graft survival was 88, 84.2 and 79.1%, respectively, and non death-censored graft survival was 82.1, 80.3 and 64.7%, respectively. Across all age groups, CVD and infections were the most frequent cause of death. The main causes of graft loss were chronic allograft dysfunction in patients <40 years old and death with functioning graft in the two remaining groups. In the multivariate analysis for graft survival, only elevated creatinine levels and proteinuria >1 g at 6 months post-transplantation were statistically significant in the three age groups. The patient survival multivariate analysis did not achieve a statistically significant common factor in the three age groups. Conclusions Five-year results show an excellent recipient survival and graft survival, especially in the youngest age group. Death with functioning graft is the leading cause of graft loss in patients >40 years. Early improvement of renal function and proteinuria together with strict control of cardiovascular risk factors are mandatory. PMID:23258810

    Background. The ANSWER study aims to identify risk factors leading to increased cardiovascular morbidity and mortality in a Spanish incident haemodialysis population. This paper summarizes the baseline characteristics of this population. Methods. A prospective, observational, one-cohort study, including all consecutive incident haemodialysis patients from 147 Spanish nephrology services, was conducted. Patients were enrolled between October 2003 and September 2004. Sociodemographic, clinical, laboratory and health care characteristics were collected. Results. Baseline characteristics are described for 2341 incident haemodialysis patients [mean (SD) age 65.2 (14.5) years, 63% males]. The main cause of renal failure was diabetic nephropathy (26%). The majority of patients (57%) had a Karnofsky score of 80–100 and 27% were followed up by a nephrologist for ≤6 months. In total, 86% of the patients had hypertension, 43% had dyslipidaemia and 44% had a history of cardiovascular disease. Initial vascular access was obtained via a temporary catheter in 30% of patients, via a permanent catheter in 16% and via an arteriovenous fistula in 54%. Albumin levels were <3.5 g/dl in 43% of patients. Immediately prior to the onset of haemodialysis, the mean (SD) glomerular filtration rate (GFR) was 7.6 (2.8) ml/min/1.73 m2, and only 6.7% of the patients were within the K/DOQI guidelines for all four bone mineral markers. In addition, a high proportion of patients had anaemia markers outside the EBPG guidelines (haemoglobin <11 g/dl, 59%, ferritin <100 or >500 ng/ml, 41% and saturated transferrin <20 or >40%, 50%) despite previous treatment with erythropoiesis-stimulating agents in 41% of cases. Conclusions. There is excessive use of temporary catheters and a high prevalence of uraemia-related cardiovascular risk factors among incident haemodialysis patients in Spain.

    Background Observational studies have reported higher mortality for patients admitted on weekends. It is not known whether this “weekend effect” is modified by clinical staffing levels on weekends. We aimed to test the hypotheses that rounds by stroke specialist physicians 7 d per week and the ratio of registered nurses to beds on weekends are associated with mortality after stroke. Methods and Findings We conducted a prospective cohort study of 103 stroke units (SUs) in England. Data of 56,666 patients with stroke admitted between 1 June 2011 and 1 December 2012 were extracted from a national register of stroke care in England. SU characteristics and staffing levels were derived from cross-sectional survey. Cox proportional hazards models were used to estimate hazard ratios (HRs) of 30-d post-admission mortality, adjusting for case mix, organisational, staffing, and care quality variables. After adjusting for confounders, there was no significant difference in mortality risk for patients admitted to a stroke service with stroke specialist physician rounds fewer than 7 d per week (adjusted HR [aHR] 1.04, 95% CI 0.91–1.18) compared to patients admitted to a service with rounds 7 d per week. There was a dose–response relationship between weekend nurse/bed ratios and mortality risk, with the highest risk of death observed in stroke services with the lowest nurse/bed ratios. In multivariable analysis, patients admitted on a weekend to a SU with 1.5 nurses/ten beds had an estimated adjusted 30-d mortality risk of 15.2% (aHR 1.18, 95% CI 1.07–1.29) compared to 11.2% for patients admitted to a unit with 3.0 nurses/ten beds (aHR 0.85, 95% CI 0.77–0.93), equivalent to one excess death per 25 admissions. The main limitation is the risk of confounding from unmeasured characteristics of stroke services. Conclusions Mortality outcomes after stroke are associated with the intensity of weekend staffing by registered nurses but not 7-d/wk ward rounds by stroke

    One hundred and fifty-three cats undergoing surgery in seven veterinary practices in Great Britain were studied. They were randomly allocated to receive either 10-20 microg/kg buprenorphine or 0.4 mg/kg butorphanol with acepromazine before anaesthesia with propofol, Saffan or thiopentone and isoflurane or halothane. Routine monitoring was undertaken. Pain and sedation were assessed blind using a four point (0-3) simple descriptive scale (SDS) at 1, 2, 4, 8 and 24h. Pain and sedation data were compared using non-parametric statistical tests and continuous data using t tests or analysis of variance (ANOVA). Anaesthesia and surgery were uneventful, and cardiorespiratory data were within normal limits. After surgery, overall, more cats had pain score 0 after buprenorphine and more had pain score 3 after butorphanol (P=0.0465). At individual time points, more cats had lower pain scores after buprenorphine at 2 (P=0.040) and 24 (P=0.036)h. At 24h 83% after buprenorphine and 63% after butorphanol had pain score 0 (P<0.04). Buprenorphine provided better and longer lasting postoperative analgesia than butorphanol. PMID:19836984

    2012-01-01

    Background Social support has been suggested to positively influence cognition and mortality in old age. However, this suggestion has been questioned due to inconsistent operationalisations of social support among studies and the small number of longitudinal studies available. This study aims to investigate the influence of perceived social support, understood as the emotional component of social support, on cognition and mortality in old age as part of a prospective longitudinal multicentre study in Germany. Methods A national subsample of 2,367 primary care patients was assessed twice over an observation period of 18 months regarding the influence of social support on cognitive function and mortality. Perceived social support was assessed using the 14-item version of the FSozU, which is a standardised and validated questionnaire of social support. Cognition was tested by the neuropsychological test battery of the Structured Interview for the Diagnosis of Dementia (SIDAM). The influence of perceived support on cognitive change was analysed by multivariate ANCOVA; mortality was analysed by multivariate logistic and cox regression. Results Sample cognitive change (N = 1,869): Mean age was 82.4 years (SD 3.3) at the beginning of the observation period, 65.9% were female, mean cognition was 49 (SD 4.4) in the SIDAM. Over the observation period cognitive function declined in 47.2% by a mean of 3.4 points. Sample mortality (N = 2,367): Mean age was 82.5 years (SD 3.4), 65.7% were female and 185 patients died during the observation period. Perceived social support showed no longitudinal association with cognitive change (F = 2.235; p = 0.135) and mortality (p = 0.332; CI 0.829-1.743). Conclusions Perceived social support did not influence cognition and mortality over an 18 months observation period. However, previous studies using different operationalisations of social support and longer observation periods indicate that such an influence may exist. This influence is

    Objective This study was designed to explore the efficacy and safety of saroglitazar 4 mg on hypertriglyceridemia in patients with HIV associated lipodystrophy. Methods During this 12-week prospective, multi-centric, open-label, single arm exploratory study, 50 patients were enrolled to receive saroglitazar 4 mg orally once daily in the morning before breakfast. The primary efficacy endpoint was the percent change in triglyceride (TG) levels from baseline to Week 6 and Week 12. The secondary efficacy endpoints were assessment of low-density-lipoprotein (LDL), very-low-density-lipoprotein (VLDL), high-density-lipoprotein (HDL), non-HDL cholesterol, total cholesterol, apo-lipoprotein (Apo) A1, Apo B, and C-peptide and fasting insulin for HOMA beta and HOMA IR. Safety assessment was performed during the study. Results Saroglitazar 4 mg significantly decreased the serum TG levels from baseline at Week 6 (percent change: -40.98; 95% CI: -50.82, -31.15) and Week 12 (percent change -45.11; 95% CI: -52.37, -37.86). Reduction in VLDL cholesterol (percent change: -46.33; 95% CI: -52.89, -39.76) and total cholesterol (percent change: 7.37; 95% CI: 1.96, 12.78) was observed at week 12 from baseline. Saroglitazar increased HDL cholesterol (percent change: 34.56, 95% CI: 22.22, 46.90), Apo A1 (percent change: 33.16; 95% CI: 18.69, 47.63) and Apo B (percent change: 10.55, 95% CI: 2.86, 18.25) levels at week 12 from baseline. Saroglitazar treatment led to increase in the C-peptide (percent change: 59.42, 95% CI: 48.78, 70.06), fasting insulin levels (percent change: 47.10; 95% CI: 38.63, 55.57), HOMA of beta cell function for C-peptide (percent change: 71.67; 95% CI: 39.09, 104.26) and HOMA of insulin resistance for C-peptide (percent change: 58.29, 95% CI: 46.74, 69.83) at week 12 from baseline. Saroglitazar treatment was safe and well tolerated in this study. Conclusion Overall, the observed changes in lipid profile after 12 weeks of saroglitazar treatment were in the direction

    Objective To provide a brief overview of the Needs and Provision Complexity Scale (NPCS) and report its first application to describe the level of ‘met’ and ‘unmet’ health/social care needs, and to estimate their costs in community-based patients with complex neurological disability. Design A multicentre prospective cohort analysis. Setting Consecutive discharges to the community from the nine tertiary specialist inpatient neurorehabilitation units in London over 12 months (2010/2011). Participants Patients responding at follow-up (n=211). Mean age 50.2(SD14) years, males:females 127/84. Diagnosis 157(74%) brain injury, 27(13%) spinal cord injury/peripheral neuropathy; 27(13%) other. Primary outcome measure The NPCS is a brief, pragmatic, directly costable instrument for measuring both an individual's needs for rehabilitation and support (NPCS-Needs) and the levels of service provided (NPCS-Gets) within a given period. Methods The ‘NPCS-Needs’ was completed by the treating clinical team at discharge. Patients and/or their carers self-reported ‘NPCS-Gets’ after 6 months by a postal/online questionnaire supported by a follow-up telephone interview. Results Needs for medical/nursing care and accommodation were generally well met. Significant shortfalls in provision were identified in the subscales of Rehabilitation (paired t test: t −9.7, p<0.001, effect size (ES)=−0.85), Social support (t −5.8, p<0.001, ES=−0.48) and Equipment (t −5.6, p<0.001, ES=−0.44). Item-level analysis demonstrated that the frequency of Personal care received exceeded predicted needs (Wilcoxon z=−3.3, p<0.001). In 80% of cases, this care was provided/paid for by families. Translated into mean costs/patient/year, the estimated underspends on Rehabilitation (−£2320) and Social support (−£1790) were exceeded >3.5-fold by excess costs of Personal care (£10 313) and Accommodation (£4296). Conclusions The results identify underprovision of community

    PubMed Central

    2014-01-01

    Background Chronic kidney disease (CKD) is common and increasing in prevalence. Cardiovascular disease (CVD) is a major cause of morbidity and death in CKD, though of a different phenotype to the general CVD population. Few therapies have proved effective in modifying the increased CVD risk or rate of renal decline in CKD. There are accumulating data that aldosterone receptor antagonists (ARA) may offer cardio-protection and delay renal impairment in patients with the CV phenotype in CKD. The use of ARA in CKD has therefore been increasingly advocated. However, no large study of ARA with renal or CVD outcomes is underway. Methods The study is a prospective randomised open blinded endpoint (PROBE) trial set in primary care where patients will mainly be identified by their GPs or from existing CKD lists. They will be invited if they have been formally diagnosed with CKD stage 3b or there is evidence of stage 3b CKD from blood results (eGFR 30–44 mL/min/1.73 m2) and fulfil the other inclusion/exclusion criteria. Patients will be randomised to either spironolactone 25 mg once daily in addition to routine care or routine care alone and followed-up for 36 months. Discussion BARACK D is a PROBE trial to determine the effect of ARA on mortality and cardiovascular outcomes (onset or progression of CVD) in patients with stage 3b CKD.

    Background A ready-to-use betamethasone valerate 0.1% (BMV) dressing was found to be superior to placebo dressing and a reference 0.1% BMV cream in the treatment of patients with chronic plaque psoriasis (CPP). Methods This multicentre, prospective, randomized, investigator-blinded, controlled, non-inferiority trial compared the efficacy and safety of the BMV dressing to the calcipotriol–betamethasone dipropionate (CBD) ointment during a 4-week treatment of patients with mild to moderate CPP. The primary efficacy endpoint was the 4-item psoriasis total severity score (TSS-4) at week 4, and the associated non-inferiority margin was 1 point. Secondary outcome measures included the psoriasis global assessment (PGA) score and patients’ quality of life (QoL). Safety was assessed through adverse events (AE) reporting in each treatment group. Results Of 325 screened patients, 324 were randomized to BMV (N = 165) or CBD (N = 159), and were considered evaluable for the safety and intention-to-treat (ITT) efficacy analyses. Per protocol (PP) populations included 133 and 131 patients in the BMV and CBD groups respectively. The mean adjusted TSS-4 significantly decreased through the study from baseline in both groups. The PP (primary) analysis of week 4 data revealed a −0.288 (95% CI: −0.610 to 0.034) not significant between-group difference in adjusted means, demonstrating non-inferiority of BMV to CBD. Non-inferiority was also demonstrated in the ITT analysis. The PGA and other secondary outcomes were significantly improved from baseline in both groups at week 4. The QoL score was slightly better in the CBD group at week 4, but no difference was observed at follow-up. No safety or tolerability concerns were observed in either group.

    Machine learning methods that have been used in data-driven predictive modeling of mineral prospectivity (e.g., artificial neural networks) invariably require large number of training prospect/locations and are unable to handle missing values in certain evidential data. The Random Forests (RF) algorithm, which is a machine learning method, has recently been applied to data-driven predictive mapping of mineral prospectivity, and so it is instructive to further study its efficacy in this particular field. This case study, carried out using data from Abra (Philippines), examines (a) if RF modeling can be used for data-driven modeling of mineral prospectivity in areas with a few (i.e., <20) mineral occurrences and (b) if RF modeling can handle evidential data with missing values. We found that RF modeling outperforms weights-of-evidence (WofE) modeling of porphyry-Cu prospectivity in the Abra area, where 12 porphyry-Cu prospects are known to exist. Moreover, just like WofE modeling, RF modeling allows analysis of the spatial associations of known prospects with individual layers of evidential data. Furthermore, RF modeling can handle missing values in evidential data through an RF-based imputation technique whereas in WofE modeling values are simply represented by zero weights. Therefore, the RF algorithm is potentially more useful than existing methods that are currently used for data-driven predictive mapping of mineral prospectivity. In particular, it is not a purely black-box method like artificial neural networks in the context of data-driven predictive modeling of mineral prospectivity. However, further testing of the method in other areas with a few mineral occurrences is needed to fully investigate its usefulness in data-driven predictive modeling of mineral prospectivity.

    Background The fixed dose antimalarial combination of dihydroartemisinin-piperaquine (DP) is a promising new artemisinin-based combination therapy (ACT). We present an individual patient data analysis of efficacy and tolerability in acute uncomplicated falciparum malaria, from seven published randomized clinical trials conducted in Africa and South East Asia using a predefined in-vivo protocol. Comparator drugs were mefloquine-artesunate (MAS3) in Thailand, Myanmar, Laos and Cambodia; artemether-lumefantrine in Uganda; and amodiaquine+sulfadoxine-pyrimethamine and artesunate+amodiaquine in Rwanda. Methods and Findings In total 3,547 patients were enrolled: 1,814 patients (32% children under five years) received DP and 1,733 received a comparator antimalarial at 12 different sites and were followed for 28–63 days. There was no significant heterogeneity between trials. DP was well tolerated with 1.7% early vomiting. There were less adverse events with DP in children and adults compared to MAS3 except for diarrhea; ORs (95%CI) 2.74 (2.13 to 3.51) and 3.11 (2.31 to 4.18), respectively. DP treatment resulted in a rapid clearance of fever and parasitaemia. The PCR genotype corrected efficacy at Day 28 of DP assessed by survival analysis was 98.7% (95%CI 97.6–99.8). DP was superior to the comparator drugs in protecting against both P.falciparum recurrence and recrudescence (P = 0.001, weighted by site). There was no difference between DP and MAS3 in treating P. vivax co-infections and in suppressing the first relapse (median interval to P. vivax recurrence: 6 weeks). Children under 5 y were at higher risk of recurrence for both infections. The proportion of patients developing gametocytaemia (P = 0.002, weighted by site) and the subsequent gametocyte carriage rates were higher with DP (11/1000 person gametocyte week, PGW) than MAS3 (6/1000 PGW, P = 0.001, weighted by site). Conclusions DP proved a safe, well tolerated, and highly effective treatment of P

    Tigecycline (TGC) has demonstrated clinical efficacy and safety, in comparison with imipenem/cilastatin in phase 3 clinical trials, for complicated intra-abdominal infection (cIAI). The present study comprised a multicentre, open-label, randomized study of TGC vs. ceftriaxone plus metronidazole (CTX/MET) for the treatment of patients with cIAI. Eligible subjects were randomized (1:1) to receive either an initial dose of TGC (100 mg) followed by 50 mg every 12 h or CTX (2 g once daily) plus MET (1-2 g daily), for 4-14 days. The primary endpoint was the clinical response in the clinically evaluable (CE) population at the test of cure (TOC) assessment. Of 473 randomized subjects, 376 were CE. Among these, clinical cure rates were 70.4% (133/189) with TGC vs. 74.3% (139/187) with CTX/MET (95% CI -13.1 to 5.1; p 0.009 for non-inferiority). Clinical cure rates for subjects with Acute Physiological and Chronic Health Evaluation II scores > or =10 were 56.8% (21/37) with TGC vs. 58.3% (21/36) with CTX/MET. The microbiologic response was similar between the two treatment arms, with microbiological eradication at TOC achieved in 68.1% (94/138) of TGC-treated subjects and 71.5% (98/137) of CTX/MET-treated subjects. (The most frequently reported adverse events (AEs) for both treatment arms were nausea (TGC, 38.6% vs CTX/MET, 27.7%) and vomiting (TGC, 23.3% vs CTX/MET, 17.7%). Overall discontinuation rates as a result of an AE were 8.9% and 4.8% in TGC- and comparator-treated subjects, respectively. The results obtained in the present study demonstrate that TGC monotherapy is non-inferior to a combination regimen of CTX/MET with respect to treating subjects with cIAI. PMID:20670293

  5. Optimization of ventilator setting by flow and pressure waveforms analysis during noninvasive ventilation for acute exacerbations of COPD: a multicentric randomized controlled trial

    2011-01-01

    Introduction The analysis of flow and pressure waveforms generated by ventilators can be useful in the optimization of patient-ventilator interactions, notably in chronic obstructive pulmonary disease (COPD) patients. To date, however, a real clinical benefit of this approach has not been proven. Methods The aim of the present randomized, multi-centric, controlled study was to compare optimized ventilation, driven by the analysis of flow and pressure waveforms, to standard ventilation (same physician, same initial ventilator setting, same time spent at the bedside while the ventilator screen was obscured with numerical data always available). The primary aim was the rate of pH normalization at two hours, while secondary aims were changes in PaCO2, respiratory rate and the patient's tolerance to ventilation (all parameters evaluated at baseline, 30, 120, 360 minutes and 24 hours after the beginning of ventilation). Seventy patients (35 for each group) with acute exacerbation of COPD were enrolled. Results Optimized ventilation led to a more rapid normalization of pH at two hours (51 vs. 26% of patients), to a significant improvement of the patient's tolerance to ventilation at two hours, and to a higher decrease of PaCO2 at two and six hours. Optimized ventilation induced physicians to use higher levels of external positive end-expiratory pressure, more sensitive inspiratory triggers and a faster speed of pressurization. Conclusions The analysis of the waveforms generated by ventilators has a significant positive effect on physiological and patient-centered outcomes during acute exacerbation of COPD. The acquisition of specific skills in this field should be encouraged. Trial registration ClinicalTrials.gov NCT01291303. PMID:22115190

    Aims The aim of this study was to evaluate the haemodynamic effects of serelaxin (30 µg/kg/day 20-h infusion and 4-h post-infusion period) in patients with acute heart failure (AHF). Methods and results This double-blind, multicentre study randomized 71 AHF patients with pulmonary capillary wedge pressure (PCWP) ≥18 mmHg, systolic blood pressure (BP) ≥115 mmHg, and estimated glomerular filtration rate ≥30 mL/min/1.73 m2 to serelaxin (n = 34) or placebo (n = 37) within 48 h of hospitalization. Co-primary endpoints were peak change from baseline in PCWP and cardiac index (CI) during the first 8 h of infusion. Among 63 patients eligible for haemodynamic analysis (serelaxin, n = 32; placebo, n = 31), those treated with serelaxin had a significantly higher decrease in peak PCWP during the first 8 h of infusion (difference vs. placebo: −2.44 mmHg, P = 0.004). Serelaxin showed no significant effect on the peak change in CI vs. placebo. Among secondary haemodynamic endpoints, a highly significant reduction in pulmonary artery pressure (PAP) was observed throughout the serelaxin infusion (largest difference in mean PAP vs. placebo: −5.17 mmHg at 4 h, P < 0.0001). Right atrial pressure, systemic/pulmonary vascular resistance, and systolic/diastolic BP decreased from baseline with serelaxin vs. placebo and treatment differences reached statistical significance at some time points. Serelaxin administration improved renal function and decreased N-terminal pro-brain natriuretic peptide levels vs. placebo. Treatment with serelaxin was well tolerated with no apparent safety concerns. Conclusion The haemodynamic effects of serelaxin observed in the present study provide plausible mechanistic support for improvement in signs and symptoms of congestion observed with this agent in AHF patients.

    Background This multicentre international randomized trial compared the impact of gadoxetic acid-enhanced magnetic resonance imaging (MRI), MRI with extracellular contrast medium (ECCM-MRI) and contrast-enhanced computed tomography (CE-CT) as a first-line imaging method in patients with suspected colorectal cancer liver metastases (CRCLM). Methods Between October 2008 and September 2010, patients with suspected CRCLM were randomized to one of the three imaging modalities. The primary endpoint was the proportion of patients for whom further imaging after initial imaging was required for a confident diagnosis. Secondary variables included confidence in the therapeutic decision, intraoperative deviations from the initial imaging-based surgical plan as a result of additional operative findings, and diagnostic efficacy of the imaging modalities versus intraoperative and pathological extent of the disease. Results A total of 360 patients were enrolled. Efficacy was analysed in 342 patients (118, 112 and 112 with gadoxetic acid-enhanced MRI, ECCM-MRI and CE-CT respectively as the initial imaging procedure). Further imaging was required in 0 of 118, 19 (17·0 per cent) of 112 and 44 (39·3 per cent) of 112 patients respectively (P < 0·001). Diagnostic confidence was high or very high in 98·3 per cent of patients for gadoxetic acid-enhanced MRI, 85·7 per cent for ECCM-MRI and 65·2 per cent for CE-CT. Surgical plans were changed during surgery in 28, 32 and 47 per cent of patients in the respective groups. Conclusion The diagnostic performance of gadoxetic acid-enhanced MRI was better than that of CE-CT and ECCM-MRI as the initial imaging modality. No further imaging was needed in the gadoxetic acid-enhanced MRI group and comparison of diagnostic efficacy parameters demonstrated the diagnostic superiority of gadoxetic acid-enhanced MRI.

    Background Intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) is recommended by WHO to prevent malaria in African pregnant women. The spread of SP parasite resistance has raised concerns regarding long-term use for IPT. Mefloquine (MQ) is the most promising of available alternatives to SP based on safety profile, long half-life, and high efficacy in Africa. We evaluated the safety and efficacy of MQ for IPTp compared to those of SP in HIV-negative women. Methods and Findings A total of 4,749 pregnant women were enrolled in an open-label randomized clinical trial conducted in Benin, Gabon, Mozambique, and Tanzania comparing two-dose MQ or SP for IPTp and MQ tolerability of two different regimens. The study arms were: (1) SP, (2) single dose MQ (15 mg/kg), and (3) split-dose MQ in the context of long lasting insecticide treated nets. There was no difference on low birth weight prevalence (primary study outcome) between groups (360/2,778 [13.0%]) for MQ group and 177/1,398 (12.7%) for SP group; risk ratio [RR], 1.02 (95% CI 0.86–1.22; p = 0.80 in the ITT analysis). Women receiving MQ had reduced risks of parasitemia (63/1,372 [4.6%] in the SP group and 88/2,737 [3.2%] in the MQ group; RR, 0.70 [95% CI 0.51–0.96]; p = 0.03) and anemia at delivery (609/1,380 [44.1%] in the SP group and 1,110/2743 [40.5%] in the MQ group; RR, 0.92 [95% CI 0.85–0.99]; p = 0.03), and reduced incidence of clinical malaria (96/551.8 malaria episodes person/year [PYAR] in the SP group and 130/1,103.2 episodes PYAR in the MQ group; RR, 0.67 [95% CI 0.52–0.88]; p = 0.004) and all-cause outpatient attendances during pregnancy (850/557.8 outpatients visits PYAR in the SP group and 1,480/1,110.1 visits PYAR in the MQ group; RR, 0.86 [0.78–0.95]; p = 0.003). There were no differences in the prevalence of placental infection and adverse pregnancy outcomes between groups. Tolerability was poorer in the two MQ groups compared to SP

    Advanced therapies such as bioengineered skin substitutes (BSS) and dehydrated human amnion/chorion membrane (dHACM) have been shown to promote healing of chronic diabetic ulcers. An interim analysis of data from 60 patients enrolled in a prospective, randomised, controlled, parallel group, multi-centre clinical trial showed that dHACM (EpiFix®, MiMedx Group Inc., Marietta, GA) is superior to standard wound care (SWC) and BSS (Apligraf®, Organogenesis, Inc., Canton, MA) in achieving complete wound closure within 4-6 weeks. Rates and time to closure at a longer time interval and factors influencing outcomes remained unassessed; therefore, the study was continued in order to achieve at least 100 patients. With the larger cohort, we compare clinical outcomes at 12 weeks in 100 patients with chronic lower extremity diabetic ulcers treated with weekly applications of Apligraf (n = 33), EpiFix (n = 32) or SWC (n = 35) with collagen-alginate dressing as controls. A Cox regression was performed to analyse the time to heal within 12 weeks, adjusting for all significant covariates. A Kaplan-Meier analysis was conducted to compare time-to-heal within 12 weeks for the three treatment groups. Clinical characteristics were well matched across study groups. The proportion of wounds achieving complete closure within the 12-week study period were 73% (24/33), 97% (31/32), and 51% (18/35) for Apligraf, EpiFix and SWC, respectively (adjusted P = 0·00019). Subjects treated with EpiFix had a very significant higher probability of their wounds healing [hazard ratio (HR: 5·66; adjusted P: 1·3 x 10(-7) ] compared to SWC alone. No difference in probability of healing was observed for the Apligraf and SWC groups. Patients treated with Apligraf were less likely to heal than those treated with EpiFix [HR: 0·30; 95% confidence interval (CI): 0·17-0·54; unadjusted P: 5·8 x 10(-5) ]. Increased wound size and presence of hypertension were significant factors that influenced healing. Mean

    STUDY QUESTION Will the use of levonorgestrel (LNG) 1.5 mg taken at each day of coitus by women who have relatively infrequent sex be an efficacious, safe and acceptable contraceptive method? SUMMARY ANSWER Typical use of LNG 1.5 mg taken pericoitally, before or within 24 h of sexual intercourse, provides contraceptive efficacy of up to 11.0 pregnancies per 100 women-years (W-Y) in the primary evaluable population and 7.1 pregnancies per 100 W-Y in the evaluable population. WHAT IS KNOWN ALREADY LNG 1.5 mg is an effective emergency contraception following unprotected intercourse. Some users take it repeatedly, as their means of regular contraception. STUDY DESIGN, SIZE, DURATION This was a prospective, open-label, single-arm, multicentre Phase III trial study with women who have infrequent coitus (on up to 6 days a month). Each woman had a follow-up visit at 2.5, 4.5 and 6.5 months after admission or until pregnancy occurs if sooner, or she decided to interrupt participation. The study was conducted between 10 January 2012 and 15 November 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 330 healthy fertile women aged 18–45 years at risk of pregnancy who reported sexual intercourse on up to 6 days a month, were recruited from four university centres located in Bangkok, Thailand; Campinas, Brazil; Singapore and Szeged, Hungary to use LNG 1.5 mg pericoitally (24 h before or after coitus) as their primary method of contraception. The participants were instructed to take one tablet every day she had sex, without taking more than one tablet in any 24-h period, and to maintain a paper diary for recording date and time for every coital act and ingestion of the study tablet, use of other contraceptive methods and vaginal bleeding patterns. Anaemia was assessed by haemoglobin evaluation. Pregnancy tests were performed monthly and pregnancies occurring during product use were assessed by ultrasound. At the 2.5-month and final visit at 6.5 months, acceptability

    Aims The current challenge in atrial fibrillation (AF) treatment is to develop effective, efficient, and safe ablation strategies. This randomized controlled trial assesses the medium-term efficacy of duty-cycled radiofrequency ablation via the circular pulmonary vein ablation catheter (PVAC) vs. conventional electro-anatomically guided wide-area circumferential ablation (WACA). Methods and results One hundred and eighty-eight patients (mean age 62 ± 12 years, 116 M : 72 F) with paroxysmal AF were prospectively randomized to PVAC or WACA strategies and sequentially followed for 12 months. The primary endpoint was freedom from symptomatic or documented >30 s AF off medications for 7 days at 12 months post-procedure. One hundred and eighty-three patients completed 12 m follow-up. Ninety-four patients underwent PVAC PV isolation with 372 of 376 pulmonary veins (PVs) successfully isolated and all PVs isolated in 92 WACA patients. Three WACA and no PVAC patients developed tamponade. Fifty-six percent of WACA and 60% of PVAC patients were free of AF at 12 months post-procedure (P = ns) with a significant attrition rate from 77 to 78%, respectively, at 6 months. The mean procedure (140 ± 43 vs. 167 ± 42 min, P<0.0001), fluoroscopy (35 ± 16 vs. 42 ± 20 min, P<0.05) times were significantly shorter for PVAC than for WACA. Two patients developed strokes within 72 h of the procedure in the PVAC group, one possibly related directly to PVAC ablation in a high-risk patient and none in the WACA group (P = ns). Two of the 47 patients in the PVAC group who underwent repeat ablation had sub-clinical mild PV stenoses of 25–50% and 1 WACA patient developed delayed severe PV stenosis requiring venoplasty. Conclusion The pulmonary vein ablation catheter is equivalent in efficacy to WACA with reduced procedural and fluoroscopy times. However, there is a risk of thrombo-embolic and pulmonary stenosis complications which needs to be addressed and prospectively monitored. Clinical

    Background. Although diosmectite has demonstrated efficacy in the treatment of acute watery diarrhoea in children, its efficacy in adults still needs to be assessed. The objective of this study was therefore to assess the efficacy of diosmectite on the time to recovery in adults with acute diarrhoea. Methods. A total of 346 adults with at least three watery stools per day over a period of less than 48 hours were prospectively randomized to diosmectite (6 g tid) or placebo during four days. The primary endpoint was time to diarrhoea recovery. Results. In the intention-to-treat population, median time to recovery was 53.8 hours (range [3.7–167.3]) with diosmectite (n = 166) versus 69.0 hours [2.2–165.2] with placebo, (n = 163; P = .029), which corresponds to a difference of 15.2 hours. Diosmectite was well tolerated. Conclusion. Diosmectite at 6 g tid was well tolerated and reduced the time to recovery of acute watery diarrhoea episode in a clinically relevant manner.

    Background: Shankha bhasma is widely used in the treatment of gastroesophageal reflux disease (GERD) patients. Aim: To compare the efficacy of two purification methods of shankha bhasma in relieving GERD symptoms. In method A, purification was done with lemon juice and method B with sour gruel. Materials and Methods: Patients with heartburn since at least four days/week but who did undergo endoscopy to assess esophageal mucosa could participate. In this single-phase, single-center, prospective, randomized control trial, the patients were randomized to receive either shankha bhasma purified by method A or by method B. The primary efficacy variable was the proportion of patients with resolution of heartburn at week 4 and week 8. Design: Single-phase, single-center, prospective, randomized control trial in a hospital setting. Results: Of the total 70 patients who received samples A and B in a randomized double-blind manner, 65% of the patients showed resolution of symptoms in sample A and 28% in sample B at the end of four weeks, whereas, 71% of the patients showed resolution of symptoms in sample A and 31% in sample B at the end of eight weeks; P value was statistically significant for resolution of symptoms (P <0.005). Conclusion: Purification of shankha bhasma by lemon juice method is better than sour gruel method in terms of clinical outcome in GERD patients and is hence recommended. PMID:23633854

    Introduction Current surgical and ablative treatment options for prostate cancer have a relatively high incidence of side effects, which may diminish the quality of life. The side effects are a consequence of procedure-related damage of the blood vessels, bowel, urethra or neurovascular bundle. Ablation with irreversible electroporation (IRE) has shown to be effective in destroying tumour cells and harbours the advantage of sparing surrounding tissue and vital structures. The aim of the study is to evaluate the safety and efficacy and to acquire data on patient experience of minimally invasive, transperineally image-guided IRE for the focal ablation of prostate cancer. Methods and analysis In this multicentre pilot study, 16 patients with prostate cancer who are scheduled for a radical prostatectomy will undergo an IRE procedure, approximately 30 days prior to the radical prostatectomy. Data as adverse events, side effects, functional outcomes, pain and quality of life will be collected and patients will be controlled at 1 and 2 weeks post-IRE, 1 day preprostatectomy and postprostatectomy. Prior to the IRE procedure and the radical prostatectomy, all patients will undergo a multiparametric MRI and contrast-enhanced ultrasound of the prostate. The efficacy of ablation will be determined by whole mount histopathological examination, which will be correlated with the imaging of the ablation zone. Ethics and dissemination The protocol is approved by the ethics committee at the coordinating centre (Academic Medical Center (AMC) Amsterdam) and by the local Institutional Review Board at the participating centres. Data will be presented at international conferences and published in peer-reviewed journals. Conclusions This pilot study will determine the safety and efficacy of IRE in the prostate. It will show the radiological and histopathological effects of IRE ablations and it will provide data to construct an accurate treatment planning tool for IRE in prostate

    2007-01-01

    We have developed a two-step procedure for preparing the skin before peripheral venous catheter (PVC) insertions. This procedure involves two successive swabbings with wipes soaked in alcoholic antiseptic. We investigated whether this two-step procedure was as effective and safe as the standard four-step procedure – washing with detergent, rinsing, drying, applying antiseptic – by carrying out a multicentre randomised equivalence study comparing the frequency of precursor signs of infection at the site of insertion for the two skin preparation procedures. The study was carried out over an eight-month period, and 248 PVC insertion sites were evaluated. The two-step procedure was used for 130 subjects and the standard procedure for 118. Taking into account all the confounding factors predisposing patients to the complications studied, the characteristics of the two groups of patients were found to be similar, with no significant differences noted. The incidence of precursor signs of infection was 11 % 24 hours after PVC insertion (27/248), 25 % at 48 hours (50/203) and at 29 % at 72 hours (34/119). Eleven patients had complications necessitating the withdrawal of the PVC: sensitivity of the insertion site, with redness and/or slight swelling and/or a palpable venous cord. No major complications were observed in this study. The frequency of local complications associated with PVCs reported in this study, whether simple or severe, was not affected by the skin preparation procedure used for PVC insertion (two-step or four-step procedure).

    Using methods of community-based participatory research, a prospective randomized controlled trial of a violence prevention program based on Latino cultural values was implemented with elementary school children in a Mexican American community. Community members participated in intervention program selection, implementation, and data collection. High-risk students who participated in the program had greater nonviolent self-efficacy and demonstrated greater endorsement of program values than did high-risk students in the control group. This collaborative partnership was able to combine community-based participatory research with a rigorous study design and provide sustained benefit to community partners. PMID:20531101

    Abstract Objective: Retrograde intrarenal surgery (RIRS) involves a minimally invasive stone surgery, lending itself potential to combined spinal-epidural anesthesia (CSEA), although it is performed preferably under general anesthesia (GA). This prospective randomized study was undertaken to evaluate the feasibility and efficacy of CSEA for patients undergoing RIRS. Patients and Methods: Seventy consecutive patients who were scheduled for RIRS were randomized to receive CSEA (n=35) or GA (n=35). Operative time, stone clearance rate, visual analog scale (VAS) of pain, complication rate, anesthetic cost, and hospital stay were compared between the two groups. Results: A total of 65 patients randomized to CSEA (31) or GA (34) completed the study. In the CSEA group, each procedure was completed and there was no anesthetic conversion. Although based on the prospective randomized method, the GA group still had a little larger stone size (p=0.059) and more multiple caliceal stones (p=0.037). Overall, there were no statistically significant differences in operative time (p=0.088), stone fragmentation time (p=0.074), postoperative VAS pain score at 6 and 24 hours (p=0.156, 0.146), incidence of complications (p=0.870), stone-free rate (p=0.804), and hospital stays (p=0.907) between the two groups. The patients in the GA group experienced a higher mean hemoglobin drop (6.5±3.2 vs 8.6±2.7 g/L, p=0.012). In addition, the anesthetic cost was much cheaper in the CSEA group (183.8±31.4 vs 391.9±59.1 dollars, p<0.001). Conclusion: RIRS with CSEA can be completed with no anesthetic conversions and with the same efficacy and safety compared with GA. When considering economical aspects, CSEA appears to be a preferable alternative to GA for the patient whose general health status permits it. PMID:25358059

    The aim of the present prospective randomized controlled trial is to compare the effectiveness of intravenous and oral antibiotic prophylaxis for cost and surgical site infection in elective laparoscopic cholecystectomy. Three hundred twenty patients were split into two groups as to include 160 patients in each, and they were evaluated in a prospective and randomized fashion. While one group was subjected to 1 g cefazolin via intravenous route during anesthesia induction, other group received 1 g cephalexin monohydrate via oral route 1 h prior to the operation. Demographic findings and operation results of the patients were compared by analyses. Our 320 patients (278 females and 42 males) received elective cholecystectomy and were followed up for a period of 6-26 months. Each group had 160 patients. Both groups were similar with regard to demographic characteristics and inclusion criteria. Among all, only five (1.5 %) cases demonstrated postoperative surgical site infection. Surgical site infection at postoperative period was determined in three (1.8 %) cases of intravenous prophylaxis group and two (1.2 %) cases of oral prophylaxis group. There was no statistically significant difference between the groups in terms of surgical site infection. Oral antibiotic prophylaxis can be used in elective laparoscopic cholecystectomy prophylaxis due to its cost-effective, reliable nature, and low surgical site infection rate. PMID:26730079

    Context: 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. Aims: Study was designed to assess and compare the effects of yogic training and swimming on resting HRV in normal healthy young volunteers. Settings and Design: Study was conducted in Department of Physiology in a medical college. Study design was prospective randomized comparative trial. Subjects and Methods: 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. Statistical Analysis Used: 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. Results: 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. Conclusion: Practicing yoga seems to be the mode of exercise with better improvement in autonomic functions as suggested by resting HRV. PMID:26170587

    Background We describe the organization of a prospective, randomized, multicenter trial comparing the effectiveness of open popliteal artery aneurysm repair (OPAR) and endovascular popliteal artery aneurysm repair (EPAR) of asymptomatic popliteal artery aneurysms (PAAs) as an example for how to use the Vascular Quality Initiative (VQI) framework. Given that many centers participate in the VQI, this model can be used to perform multicenters’ prospective trials on very modest budget. Methods VQI prospectively collects data on many vascular procedures. These data include many important perioperative, intraoperative, and postoperative details regarding both patients and their procedures. We describe a study where minimal changes to the collected data by participating centers can provide level-1 evidence regarding a significant clinical question. Data will be collected using modified VQI forms within the existing VQI data reporting structure. We plan to enroll 148 patients with asymptomatic PAAs into the open and endovascular surgery cohorts. Patients from participating VQI centers will be randomized 1:1 to either OPAR or EPAR and will be followed for an average of 2.5 years. Our primary hypothesis is that major adverse limb event–free survival is lower in the EPAR cohort and that EPAR is associated with more secondary interventions, improved quality of life, and decreased length of stay. The budget for this trial is fixed at $10,000/year for the course of the study, and the trial is judged to be feasible because of the functionality of the VQI platform. Conclusions Using the existing VQI infrastructure, Open versus Endovascular Repair of Popliteal Artery Aneurysm will provide level 1 data for PAA treatment on a modest budget. The proposed trial has an adequately powered comparative design that will use objective performance goals to describe limb-related morbidity and procedural reintervention rates. PMID:25311746

    Objectives Despite increased use of integrative medicine in cancer therapy, little data exist on its efficacy. This prospective, randomized, pilot trial sought to evaluate the feasibility of combined modality integrative medicine (CM-IM) in women with ovarian cancer (OvCA) and evaluate its effects on quality of life (QoL), chemotherapy toxicity and immunologic profiles. Methods Women with newly diagnosed OvCA requiring chemotherapy were offered enrollment. Those randomized to the experimental arm received hypnosis, therapeutic massage and healing touch with each cycle of chemotherapy. The control arm received chemotherapy without CM-IM. All patients completed QoL questionnaires prior to cycles 1, 3 and 6, and 6-months after chemotherapy. Immunologic profiles were measured. Statistical analysis was based on intent-to-treat. Student’s t-test and Fischer’s exact-test were used to determine differences. Results Forty-three women enrolled. All women randomized to CM-IM were successfully treated. There were no statistical differences between the groups in age, stage, grade, histologic cell type, CA125 levels, or surgical cytoreductive status. There was no difference in overall QoL measurements. Re-hospitalization rates, treatment delays, anti-emetic use, and infection rates were similar. Immunologic profiles revealed no difference between arms for WBC or salivary IgA levels. Women receiving CM-IM had consistently higher levels of CD4, CD8 and NK cells, although this did not reach statistical significance. Conclusions Prospective clinical evaluation of integrative medicine for women with gynecologic malignancy is feasible. This first, pilot study of CM-IM in gynecologic oncology demonstrated no improvement in QoL or chemotherapy toxicity. Integrative medicine-associated improvements in immunologic profiles warrant further investigation. PMID:21864886

    OBJECTIVE: The purpose of this randomized, prospective clinical trial was to determine whether hypothermia during resuscitation is protective or harmful to critically injured trauma patients. SUMMARY BACKGROUND DATA: Hypothermia has both protective and harmful clinical effects. Retrospective studies show higher mortality in patients with hypothermia; however, hypothermia is more common in more severely injured patients, which makes it difficult to determine whether hypothermia contributes to mortality independently of injury severity. There are no randomized, prospective treatment studies to assess hypothermia's impact as an independent variable. METHODS: Fifty-seven hypothermic (T < or = 34.5 C), critically injured patients requiring a pulmonary artery catheter were randomized to a rapid rewarming protocol using continuous arteriovenous rewarming (CAVR) or to a standard rewarming (SR) control group. The primary outcome of interest was first 24-hour blood product and fluid resuscitation requirements. Other comparative analyses included coagulation assays, hemodynamic and oxygen transport measurements, length of stay, and mortality. RESULTS: The two groups were well matched for demographic and injury severity characteristics. CAVR rewarmed significantly faster than did SR (p < 0.01), producing two groups with different amounts of hypothermia exposure. The patients who underwent CAVR required less fluid during resuscitation to the same hemodynamic goals (24,702 mL vs. 32,540 mL, p = 0.05) and were significantly more likely to rewarm (p = 0.002). Only 2 (7%) of 29 patients who underwent CAVR failed to warm to 36 C and both died, whereas 12 (43%) of 28 patients who underwent SR failed to reach 36 C, and all 12 died. Patients who underwent CAVR had significantly less early mortality (p = 0.047). CONCLUSION: Hypothermia increases fluid requirements and independently increases acute mortality after major trauma.

    Clostridium difficile infection (CDI) is the major cause of infective diarrhoea in healthcare environments. As part of the European, multicentre, prospective, biannual, point-prevalence study of Clostridium difficile infection in hospitalised patients with diarrhoea (EUCLID), the largest C. difficile epidemiological study of its type, PCR ribotype distribution of C. difficile isolates in Europe was investigated. PCR ribotyping was performed on 1,196 C. difficile isolates from diarrhoeal samples sent to the European coordinating laboratory in 2012-13 and 2013 (from two sampling days) by 482 participating hospitals from 19 European countries. A total of 125 ribotypes were identified, of which ribotypes 027 (19%, n =222), 001/072 (11%, n = 134) and 014/020 (10%, n = 119) were the most prevalent. Distinct regional patterns of ribotype distribution were noted. Of 596 isolates from patients with toxin-positive stools (CDI cases), ribotype 027 accounted for 22% (32/144) of infections in cases aged from 18 to less than 65 years, but the prevalence decreased in those aged ≥ 65 years (14% (59/412)) and further decreased in those aged ≥ 81 years (9% (18/195)). The prevalence of ribotype 027 and 176, but not other epidemic strains, was inversely proportional to overall ribotype diversity (R(2) = 0.717). This study highlights an increased diversity of C. difficile ribotypes across Europe compared with previous studies, with considerable intercountry variation in ribotype distribution. Continuous surveillance programmes are necessary to monitor the changing epidemiology of C. difficile. PMID:27470194

    OBJECTIVE: To assess the recently proposed preliminary criteria for the classification of Sjögren's syndrome (SS) in a multicentre European study of a new series of clinically defined cases. METHODS: The criteria included six items: I = ocular symptoms; II = oral symptoms; III = evidence of keratoconjunctivitis sicca; IV = focal sialoadenitis by minor salivary gland biopsy; V = instrumental evidence of salivary gland involvement; VI = presence of autoantibodies. Each centre was asked to provide five patients with primary SS, five with secondary SS, five with connective tissue diseases (CTD) but without SS, and five controls (patients with ocular or oral features that may simulate SS). The preliminary six item classification criteria set was applied to both the SS patients and the non-SS controls, and the performance of the criteria in terms of sensitivity and specificity was tested. RESULTS: The criteria set was tested on a total of 278 cases (157 SS patients and 121 non-SS controls) collected from 16 centres in 10 countries. At least four of the six items in the criteria set (limiting item VI to the presence of Ro(SS-A) or La(SS-B) antibodies) were present in 79 of 81 patients initially classified as having primary SS (sensitivity 97.5%), but in only seven of 121 non-SS controls (specificity 94.2%). When the presence of item I or II plus any two of items III-V of the criteria set was considered as indicative of secondary SS, 97.3% (71 of 73) of the patients initially defined as having this disorder and 91.8% (45 of 49) of the control patients with CTD without SS were correctly classified. CONCLUSION: This prospective study confirmed the high validity and reliability of the classification criteria for SS recently proposed by the European Community Study Group. PMID:8712861

    BACKGROUND: Osmotic release oral system (OROS®) hydromorphone is a potent, long-acting opioid analgesic, effective and safe for controlling cancer pain in patients who have received other strong opioids. To date, few studies have examined the efficacy of hydromorphone for pain relief in opioid-naive cancer patients. OBJECTIVES: A prospective, open-label, multicentre trial was conducted to determine the efficacy and tolerability of OROS hydromorphone as a single and front-line opioid therapy for patients experiencing moderate to severe cancer pain. METHODS: OROS hydromorphone was administered to patients who had not previously received strong, long-acting opioids. The baseline evaluation (visit 1) was followed by two evaluations (visits 2 and 3) performed two and 14 weeks later, respectively. The starting dose of OROS hydromorphone was 4 mg/day and was increased every two days when pain control was insufficient. Immediate-release hydromorphone was the only accepted alternative strong opioid for relief of breakthrough pain. The efficacy, safety and tolerability of OROS hydromorphone, including the effects on quality of life, and patients’ and investigators’ global impressions on pain relief were evaluated. The primary end point was pain intensity difference (PID) at visit 2 relative to visit 1 (expressed as %PID). RESULTS: A total of 107 patients were enrolled in the present study. An improvement in pain intensity of >50% (≥50% PID) was observed in 51.0% of the full analysis set and 58.6% of the per-protocol set. The mean pain score, measured using a numerical rating scale, was significantly reduced after two weeks of treatment, and most adverse events were manageable. Quality of life also improved, and >70% of patients and investigators were satisfied with the treatment. CONCLUSIONS: OROS hydromorphone provided effective pain relief and improved quality of life in opioid-naive cancer patients. As a single and front-line treatment, OROS hydromorphone delivered

    Despite the need for effective and safe thromboprophylactic drugs for patients with renal impairment, clinical trial data on anticoagulant agents are limited in this population. The study aim was to assess in the real-world setting the use of the once-daily 1.5 mg reduced dosage regimen of fondaparinux available for this context. In this prospective cohort study, patients with a creatinine clearance (CrCl) of 20-50 ml/minute, undergoing total hip (THR) or knee (TKR) replacement or hip fracture surgery (HFS) received fondaparinux thromboprophylaxis. Main clinical outcomes were bleeding (major/clinically relevant non-major), symptomatic venous thromboembolism (VTE) and death. Overall, 442 patients (353 women; median age: 82 years; 39.4% in ASA class ≥3; mean ± SD CrCl: 39.0 ± 8.0 ml/minute; 78% with additional risk factors for bleeding), undergoing THR (43.7%), TKR (27.6%), or HFS (28.7%) received fondaparinux 1.5 mg for a mean ± SD duration of 16.0 ± 12.5 days. At postoperative day 10, the rates (95% confidence interval) of major bleeding, clinically relevant bleeding and symptomatic VTE were 4.5% (2.8-6.9), 0.5% (0.1-1.6) and 0.5% (0.05-1.62), respectively; no fatal bleeding, bleeding into a critical organ, pulmonary embolism or proximal deep-vein thrombosis occurred. Corresponding rates at one month were 5.2%, 0.7% and 0.7%. One-month mortality was 2.3% (0.9-3.6). This large clinical prospective study provides for the first time, under conditions reflecting "real-world" routine clinical practice, data on the bleeding and VTE risks of thromboprophylaxis with fondaparinux 1.5 mg after major orthopaedic surgery in renally impaired patients. It shows that these patients constitute a very elderly and fragile population. PMID:22476471

    Netilmicin or tobramycin was administered to 197 patients in a prospective randomized double-blind trial. Of these patients, 140 recipients of nine or more doses of netilmicin or tobramycin could be evaluated for nephrotoxicity. Fifty-five patients were able to cooperate in the administration of serial audiograms. Nephrotoxicity of similar severity developed in 7 of 73 (9.6%) recipients of tobramycin and in 7 of 67 (10.4%) recipients of netilmicin (P greater than 0.05). Mild or slight auditory toxicity developed in 5 of 28 (17.8%) recipients of tobramycin and in 2 of 27 (7.4%) recipients of netilmicin (P greater than 0.05). PMID:6393868

    Objective. To determine the impact of a single, 3-day intervention on empathy levels as measured by the validated Jefferson Scale of Empathy-Health Profession Students version (JSE-HPS). Methods. Forty second-year student pharmacists were recruited to participate in a non-blinded prospective study. Subjects were randomized to an intervention group (n=20) or control group (n=20) and completed the JSE-HPS at baseline, 7 days postintervention, and 90 days postintervention. The intervention group consisted of a 3-day simulation, each day including a designated activity with loss of dominant hand usage, vision, and speech. Results. The 3-day simulation increased empathy levels in the intervention group compared to the control group 7 days postintervention (p=0.035). However, there were no effects on empathy levels 90 days postintervention (p=0.38). Conclusion. Empathy scores increased but were not sustained in the long-term with a 3-day empathy intervention.

    In a monocenter prospective randomized double-blind clinical trial the efficacy of homeopathic treatment was investigated on children with adenoid vegetations justifying an operation. Patients were treated with either homeopathic remedies such as Nux vomica D200, Okoubaka D3, Tuberculinum D200, Barium jodatum D4 and Barium jodatum D6 or with placebo. The duration of the study for each patient was 3 months. Examination of the ears using a microscope, rhinoscopy, stomatoscopy and pharyngoscopy, as well as tympanometry and audiometry were performed after 4, 8 and 12 weeks. Out of a total of 97 children studied between the ages of 4 to 10 years 82 could be analyzed. At the end of the study no operation was required in 70.7% of the placebo-treated children and in 78.1% of the children treated with homeopathic preparations. These results show no statistical significance. PMID:9378668

    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. PMID:7785999

    We report the results of a random, prospective study of electrical clipping versus routine razor shaving in the removal of hair immediately before operation. Two hundred patients having elective inguinal herniorrhaphy according to strict protocol were included in this study. Unsatisfactory skin preparation, as evidenced by gross cuts made in the skin during hair removal, was noted in 7% of those shaved and 4% of those clipped. Two subcutaneous wound infections occurred in the shaved group (2%) and one in the clipped group (1%). This study indicates that preoperative clipping of hair with electric barber's clippers immediately before operation is a safe, well tolerated procedure that does not increase the risk of postoperative wound infection.

    In most cases traveler's diarrhea is a self-limiting disease not requiring professional assistance. As data on self-treatment are very limited, a prospective randomized trial was performed in 620 German tourists spending a two week-holiday in Turkey. 31.6% of these travelers developed diarrhea and 186 were assigned to two treatment groups, receiving either medical coal or a combination of tannalbuminate and ethacridinlactate (TA/EL). In the TA/EL group stool frequencies significantly earlier returned to normal and complaints of moderate to severe abdominal pain were recorded less frequently (50 vs. 82.2%) than in patients receiving charcoal preparations. Both medications were well tolerated and TA/EL appeared more efficient for self medication of uncomplicated traveler's diarrhea. PMID:1287425

    Sixty patients with gynecologic cancer entered a prospective, randomized study of immediate postoperative feeding. Thirty-three women in the study group received an elemental diet (Vivonex HN) delivered through a needle catheter jejunostomy. Twenty-seven patients in the control group were given standard 5% dextrose and electrolyte solutions. Patients in both groups were stratified according to nutritional status as determined by anthropometric evaluation and levels of serum albumin, total protein, and transferrin. These parameters also were measured at intervals throughout the study. Only one catheter-related complication occurred. Patients in the study group received significantly more calories (p = 0.01) and were better able to maintain serum levels of transferrin (p = 0.05) than those in the control group. An elemental diet administered through the needle catheter jejunostomy effectively maintains postoperative nutrition and is associated with few complications. PMID:3132853

    The aim of this study was to compare the efficacy of two embryo transfer catheters: Wallace and Rocket Embryon in an IVF programme of a tertiary referral university centre. A total of 308 patients undergoing embryo transfer were prospectively randomized to either a transfer with the Wallace catheter or a transfer with the Rocket catheter. The main outcome measure in this study was the clinical pregnancy rate, and secondary outcome measures included implantation rate, visibility of the catheter under ultrasound, number of retained embryos post transfer, and whether change of catheter was required. In addition, patient discomfort during the procedure was recorded. Pregnancy and implantation rates were similar when Wallace or Rocket catheters were used. However, for the Rocket catheter, the tip was more often clearly seen on ultrasound and it had a lower rate of retained embryos in the catheter after transfer (P < 0.05). Experience with different transfer catheters is recommended for difficult cases. PMID:18854110

    Purpose. The present prospective randomized adjuvant trial was carried out to compare the toxicity, feasibility and efficacy of augmented chemotherapy added to hyperfractionated accelerated radiotherapy after wide or marginal resection of grade 2 and grade 3 soft tissue sarcoma (STS). Patients and methods. Fifty-nine patients underwent primary surgery by wide or marginal excision and were subsequently randomized to receive radiotherapy alone or under the addition of six courses of ifosfamide (1500 mg/m2 , days 1–4), dacarbazine (DTIC) (200 mg/m2 , days 1–4) and doxorubicin (25 mg/m2 , days 1–2) administered in 14-day-intervals supported by granulocyte-colony stimulating factor (30 × 106 IU/day, s.c.) on days 5–13. According to the randomization protocol, 28 patients received radiotherapy only, whereas 31 patients were treated with additional chemotherapy. Results. The relative ifosfamide–doxorubicin–DTIC (IFADIC) dose intensity achieved was 93%. After a mean observation period of 41±19.7 months (range, 8.1–84 months), 16 patients (57%) in the control group versus 24 patients (77%) in the chemotherapy group were free of disease (p>0.05).Within the control group, tumor relapses occurred in 12 patients (43%;six patients with distant metastases, two with local relapse, four with both) versus seven patients (23%; five patients with distant metastases, one with local recurrence, one with both) from the chemotherapy group. Relapse-free survival (RFS) (p=0.1), time to local failure (TLF) (p=0.09), time to distant failure (TDF) (p=0.17) as well as overall survival (OS) (p=0.4) did not differ significantly between the two treatment groups. Treatment-related toxicity was generally mild in both treatment arms. Conclusion. We conclude that the safety profile of intensified IFADIC added to radiotherapy was manageable and tolerable in the current setting. Inclusion of intensified IFADIC was not translated into a significant benefit concerning OS, RFS, TLF and

    This was a double-blind, randomized, placebo-corrected, outpatient, multi-centre (five sites) clinical study, in which a total of 168 Caucasian early-postmenopausal women volunteers (age>49 years) participated after fulfilling the criteria: follicle stimulating hormone (FSH) >30 IU/ml and estrogen (E2) <40 pg/ml levels at admission. They were randomly allocated to Placebo and Pre-Gelatinized Organic Maca (Maca-GO) treatment, according to different monthly treatment sequences scheduled for each site. Two 500 mg vegetable hard gel capsules with Maca-GO or Placebo powder were self-administered twice daily with meals (total 2 g/day) during three (Trial I; n=102) or four (Trial II; n=66) months study periods. At the baseline and follow- up monthly intervals, blood levels of FSH, E2, progesterone (PRG) and lutinizing hormone (LH), as well as serum cholesterol (CHOL), triglycerides (TRG), high- and low density lipoproteins (HDL and LDL) were measured. Menopausal symptoms were assessed according to Greene’s Score (GMS) and Kupperman’s Index (KMI). Data were analyzed using multivariate technique on blocs of monthly results in one model and Maca versus Placebo contrast in another model. A total of 124 women concluded the study. Maca-GO significantly stimulated production of E2 (P<0.001) with a simultaneous suppression (P<0.05) of blood FSH, increase (P<0.05) in HDL. Maca-GO significantly reduced both frequency and severity of individual menopausal symptoms (hot flushes and night sweating in particular) resulting in significant (P<0.001) alleviation of KMI (from 22 to 10), thus, offering an attractive non-hormonal addition to the choices available to early-postmenopausal women in the form of a natural plant alternative to Hormone Replacement Therapy (HRT) – hence, reducing dependence on hormone therapy programs.

    Objective: The HepatAssist liver support system is an extracorporeal porcine hepatocyte-based bioartificial liver (BAL). The safety and efficacy of the BAL were evaluated in a prospective, randomized, controlled, multicenter trial in patients with severe acute liver failure. Summary Background Data: In experimental animals with acute liver failure, we demonstrated beneficial effects of the BAL. Similarly, Phase I trials of the BAL in acute liver failure patients yielded promising results. Methods: A total of 171 patients (86 control and 85 BAL) were enrolled. Patients with fulminant/subfulminant hepatic failure and primary nonfunction following liver transplantation were included. Data were analyzed with and without accounting for the following confounding factors: liver transplantation, time to transplant, disease etiology, disease severity, and treatment site. Results: For the entire patient population, survival at 30 days was 71% for BAL versus 62% for control (P = 0.26). After exclusion of primary nonfunction patients, survival was 73% for BAL versus 59% for control (n = 147; P = 0.12). When survival was analyzed accounting for confounding factors, in the entire patient population, there was no difference between the 2 groups (risk ratio = 0.67; P = 0.13). However, survival in fulminant/subfulminant hepatic failure patients was significantly higher in the BAL compared with the control group (risk ratio = 0.56; P = 0.048). Conclusions: This is the first prospective, randomized, controlled trial of an extracorporeal liver support system, demonstrating safety and improved survival in patients with fulminant/subfulminant hepatic failure.

    Background and Objectives: To compare laparoscopic transperitoneal versus retroperitoneoscopic pyeloplasty for primary ureteropelvic junction obstruction in a prospective randomized manner and assess overall results with long-term follow-up. Methods: In this prospective study, from 2008 to 2012, 112 cases of primary ureteropelvic junction obstruction were randomized in a 1:1 ratio into 2 groups. Group I included patients who underwent transperitoneal laparoscopic pyeloplasty, and group II consisted of patients who underwent retroperitoneoscopic laparoscopic pyeloplasty. Demographic and clinical characteristics and postoperative and operative data were collected and analyzed. The statistical analysis was performed with the Fisher exact test, χ2 test, and Mann-Whitney U test for independent groups, and P < .05 was considered statistically significant. Results: The total operative time and intracorporeal suturing time were significantly higher in group II than in group I (P < .001). The visual analog scale score for pain on postoperative day 1 and the requirement for tramadol were significantly higher in group I than in group II (P = .004). The hospital stay and the rate of temporary ileus were significantly greater (P < .036 and P < .02, respectively) in group I than in group II. The success rate of transperitoneal laparoscopic pyeloplasty versus retroperitoneoscopic laparoscopic pyeloplasty was 96.4% versus 96.6% with a mean follow-up period of 30.75 ± 4.85 months versus 30.99 ± 5.59 months (P < .88). Conclusion: Transperitoneal laparoscopic pyeloplasty is associated with significantly greater postoperative pain, a higher tramadol dose, a higher rate of ileus, and a longer hospital stay in comparison with retroperitoneoscopic laparoscopic pyeloplasty. Although the operative time for retroperitoneoscopic laparoscopic pyeloplasty is significantly longer, the success rate remains the same for both procedures. PMID:25392671

  19. Aprotinin and classic wound drainage are unnecessary in total hip replacement a prospective randomized trial

    PubMed Central

    2011-01-01

    Background Classic wound drainage is still common in hip replacement but its benefit is doubtful. The role of systemic administration of proteinase inhibitors like aprotinin to avoid perioperative blood loss is still unclear. Patients and Methods In a prospective randomized trial, the perioperative blood loss in alloplastic hip replacement under the influence of proteinase inhibitor (aprotinin, Trasylol®) using wound drainage as well as compression treatment alone were compared. 80 patients were prospectively randomized in 4 arms. Patients received either aprotinin or placebo during surgery as well as drainage or targeted external wound compression. Results Observing the "drug therapy" aprotinin had no effect on the intraor postoperative blood loss (p > 0.05), a trend to lower postoperative hemoglobin decline was found, but without significance. thrombosis occurred in neither the aprotinin nor in the placebo group. Two patients had a severe allergic drug reaction and were excluded from the study. Under "non drug therapy" with compression therapy and wound drainage a significant difference in blood loss was found (p < 0.001). The blood loss was higher under the wound drainage. There was no influence on the infection rate. Yet we could observe increased bruising under the sole external compression treatment. Conclusion The administration of aprotinin did not achieve the desired reduction of perioperative blood loss. Hence, costs and two severe allergic drug reactions in our study represent arguments against its use in regular treatment. Furthermore, it seems that wound drainage is neglectable in hip replacement and can be substituted by a sole compression treatment. PMID:21345766

  20. The Belgian Diabetes in Pregnancy Study (BEDIP-N), a multi-centric prospective cohort study on screening for diabetes in pregnancy and gestational diabetes: methodology and design

    PubMed Central

    2014-01-01

    Background The International Association of Diabetes and Pregnancy Study Groups (IADPSG) recommends universal screening with a 75 g oral glucose tolerance test (OGTT) using stricter criteria for gestational diabetes (GDM). This may lead to important increases in the prevalence of GDM and associated costs, whereas the gain in health is unclear. The goal of ‘The Belgian Diabetes in Pregnancy Study’ (BEDIP-N) is to evaluate the best screening strategy for pregestational diabetes in early pregnancy and GDM in an ethnically diverse western European population. The IADPSG screening strategy will be followed, but in addition risk questionnaires and a 50 g glucose challenge test (GCT) will be performed, in order to define the most practical and most cost effective screening strategy in this population. Methods BEDIP-N is a prospective observational cohort study in 6 centers in Belgium. The aim is to enroll 2563 pregnant women in the first trimester with a singleton pregnancy, aged 18–45 years, without known diabetes and without history of bariatric surgery. Women are universally screened for overt diabetes and GDM in the first trimester with a fasting plasma glucose and for GDM between 24–28 weeks using the 50 g GCT and independently of the result of the GCT, all women will receive a 75 g OGTT using the IADPSG criteria. Diabetes and GDM will be treated according to a standardized routine care protocol. Women with GDM, will be reevaluated three months postpartum with a 75 g OGTT. At each visit blood samples are collected, anthropometric measurements are obtained and self-administered questionnaires are completed. Recruitment began in April 2014. Discussion This is the first large, prospective cohort study rigorously assessing the prevalence of diabetes in early pregnancy and comparing the impact of different screening strategies with the IADPSG criteria on the detection of GDM later in pregnancy.

    Background: Robust markers that predict prognosis and detect early treatment response in malignant pleural mesothelioma (MPM) would enhance patient care. Methods: Consecutive patients with MPM who were considered fit for first-line chemotherapy were prospectively recruited. Patients of similar performance status opting for best supportive care were included as a comparator group. Baseline and interval CT, PET-CT and serum markers (mesothelin, fibulin-3 and neutrophil–lymphocyte ratio (NLR)) were obtained, and patients followed up for a minimum 12 months. Findings: Seventy-three patients were recruited (58 chemotherapy/15 comparator arm). Baseline TGV (total glycolytic volume on PET-CT) was an independent predictor of worse overall survival (OS) (P=0.001). Change in interval TGV(baseline/after two cycles of chemotherapy) did not predict OS or chemotherapy response on CT. Baseline NLR<4 was an independent predictor of better OS (median survival 453 (IQR 272–576) days vs NLR⩾4, 257 (IQR 147–490), P=0.002). Although baseline serum mesothelin did not predict OS, a falling level at 8 weeks significantly predicted longer time to progression (TTP) (P<0.001). Interpretation: Neutrophil–lymphocyte ratio and baseline TGV predict prognosis in malignant pleural mesothelioma (MPM), but PET-CT is unhelpful in monitoring chemotherapy response. Serum mesothelin is a useful early treatment response marker when measured serially during chemotherapy and may have a role in evaluating patients' treatment response. PMID:25756396

    Background In India alone, more than one million people die yearly due to trauma. Identification of patients at risk of early mortality is crucial to guide clinical management and explain prognosis. Prediction models can support clinical judgement, but existing models have methodological limitations. The aim of this study was to derive a vital sign based prediction model for early mortality among adult trauma patients admitted to three public university hospitals in urban India. Methods We conducted a prospective cohort study of adult trauma patients admitted to three urban university hospitals in India between October 2013 and January 2014. The outcome measure was mortality within 24 hours. We used logistic regression with restricted cubic splines to derive our model. We assessed model performance in terms of discrimination, calibration, and optimism. Results A total of 1629 patients were included. Median age was 35, 80% were males. Mortality between admission and 24 hours was 6%. Our final model included systolic blood pressure, heart rate, and Glasgow coma scale. Our model displayed good discrimination, with an area under the receiver operating characteristics curve (AUROCC) of 0.85. Predicted mortality corresponded well with observed mortality, indicating good calibration. Conclusion This study showed that routinely recorded systolic blood pressure, heart rate, and Glasgow coma scale predicted early hospital mortality in trauma patients admitted to three public university hospitals in urban India. Our model needs to be externally validated before it can be applied in the clinical setting. PMID:25180494

    The aim of this single-center, prospective, randomized, parallel-group study was to compare Dienogest and Danazol as endometrial preparation in patients who have to undergo hysteroscopic surgery for submucous myomas. We enrolled 80 consecutive eligible patients, in reproductive age, affected by submucous myomas. Pre- and posttreatment characterization of endometrium was performed by hysteroscopic visual observation and histologic confirmation. The enrolled patients were randomly assigned to two groups: 40 were treated with 2 mg of Dienogest/die, 40 with 100 mg of Danazol/die, both orally for 5 weeks, starting on day 1 of menstruation. Posttreatment comparison of endometrial patterns showed a significant more marked effect of Dienogest, respect to Danazol, in atrophying endometrium ("normotrophic non-responders" versus "hypotrophic"-"atrophic", p = 0.028). Intraoperative data showed no significant difference between the two groups for cervical dilatation time (p = 0.326), while in the Dienogest group, we found a significant reduction of operative time (p = 0.001), infusion volume (p = 0.001), and severity of bleeding (p = 0.042). Moreover, Dienogest caused less side effects (p = 0.008). According to our data analysis, Dienogest, respect to Danazol, is more effective for the preparation of the endometrium in patients who have to undergo hysteroscopic surgery for submucous myomas, and causes less side effects.

    Objective To investigate the teaching of cognitive skills within a technical skills course, we carried out a blinded, randomized prospective study. Methods Twenty-one junior residents (postgraduate years 1– 3) from a single program at a surgical-skills training centre were randomized to 2 surgical skills courses teaching total knee arthroplasty. One course taught only technical skill and had more repetitions of the task (5 or 6). The other focused more on developing cognitive skills and had fewer task repetitions (3 or 4). All were tested with the Objective Structured Assessment of Technical Skill (OSATS) both before and after the course, as well as a pre- and postcourse error-detection exam and a postcourse exam with multiple-choice questions (MCQs) to test their cognitive skills. Results Both groups' technical skills as assessed by OSATS were equivalent, both pre- and postcourse. Taking their courses improved the technical skills of both groups (OSATS, p < 0.01) over their pre-course scores. Both groups demonstrated equivalent levels of knowledge on the MCQ exam, but the cognitive group scored better on the error-detection test (p = 0.02). Conclusions Cognitive skills training enhances the ability to correctly execute a surgical skill. Furthermore, specific training and practice are required to develop procedural knowledge into appropriate cognitive skills. Surgeons need to be trained to judge the correctness of their actions.

    Renal failure is a frequent complication of multiple myeloma (MM) that strongly affects patient survival. Although a variety of renal diseases may be observed in MM, myeloma cast nephropathy (MCN), a tubulo-interstitial disorder related to precipitation of a monoclonal light chain (LC) within tubular distal lumens, is the main cause of severe and persistent renal failure. To date, the respective frequency and initial evolution of renal disorders associated with monoclonal LC in MM remain poorly defined. Treatment of MCN relies on urgent symptomatic measures and rapid introduction of chemotherapy to reduce the production of monoclonal LC. The introduction of novel chemotherapy regimens based on the association of bortezomib with dexamethasone is likely to have improved the prognosis of MM patients with renal failure. In addition, the combination of novel agents with efficient removal of circulating LC through high cut-off hemodialysis membrane may further increase renal response rate. However, the impact on patient and renal outcomes of these potential therapeutic advances has not been evaluated in prospective studies. The randomized trials EuLITE in the UK and Germany and MYRE in France should help to answer these issues. MYRE is a randomized controlled phase III trial (NCT01208818) that aims to better define the epidemiology and typology of inaugural renal failure in MM and to optimize therapy of MCN patients with and without dialysis-dependent renal failure.

    A prospective randomized trial of 157 patients with malignant astrocytomas (Grade III or IV) was carried out at a single institution. The minimization technique ensured balanced distribution of prognostic factors between the treatment groups. All received oral lomustine (CCNU, 80 mg/m/sup 2/) six weekly and hydroxyurea (HU, 3.5 gm/m/sup 2/ over 5 days) three weekly, for one year or until recurrence, with doses adjusted for myelosuppression. Patients were randomized to daily (5000 rad in 25 fractions (fr) in 5 weeks) or Q3h (every 3 hours) Cobalt 60 irradiation (3600-4000 rad in 36-40 fr of 100 rad each, given 4 fr per day at 3-hour intervals over two weeks). Steroid therapy (up to 16 mg day dexamethasone) was permitted. Complications were moderate and equivalent in the two groups. No significant survival or toxicity differences were seen between the two groups. Age, initial performance status, and extent of surgical resection were found to be significant (P<0.01) prognostic factors for survival. Median survival of the whole group was 48 weeks with a minimum follow-up of one year. There was no advantage to large radiation fields. The hyperfractionation and daily regimes had similar efficacy and toxicity. Hyperfractionation with chemotherapy offers a useful alternative approach in the management of this disease.

    Rifaximin has been reported to be effective for the treatment of hepatic encephalopathy (HE) in Europe. However, it is unknown whether Rifaximin is effective for the treatment of HE in Koreans, therefore we conducted a open-label prospective randomized study to evaluate the efficacy of rifaximin versus lactulose in Korean patients. Fifty-four patients with liver cirrhosis and hepatic encephalopathy were enrolled. Thirty-two patients were randomized to receive rifaximin and 22 to receive lactulose both over a 7-day periods. Before and at the end of treatment, gradation of blood ammonia, flapping tremor, mental status, number connection test (NCT) were performed and estimation of HE indexes determined. Both rifaximin and lactulose were effective in the majority of patients (84.4% and 95.4%, respectively, p=0.315). Blood NH3, flapping tremor, mental status, and NCT was significantly improved by rifaximin and lactulose, and the posttreatment levels of these measures were similar for the rifaximin and lactulose-treated groups, as was the HE index (rifaximin group (10.0→4.2, p=0.000); lactulose group (11.3→5.0, p=0.000)). One patient treated with rifaximin complained of abdominal pain, which was easily controlled. There was no episode of renal function impairment in either treatment group. Rifaximin proved to be as safe and as effective as lactulose for the treatment of Korean patients with hepatic encephalopathy. PMID:15988813

    Background and study aims: In this study, we aim to determine the safety and feasibility of an alcohol-free approach to pancreatic cyst ablation using a chemotherapeutic ablation cocktail. Patients and methods: In this prospective, randomized, double-blinded pilot study, 10 patients with known mucinous type pancreatic cysts underwent endoscopic ultrasound (EUS)-guided fine needle aspiration and then lavage with either 80 % ethanol or normal saline. Both groups were then treated with a cocktail of paclitaxel and gemcitabine. Primary outcomes were reduction in cyst volume and rates of complications. Results: At 6 months, patients randomized to the alcohol arm had an 89 % average volume reduction, with a 91 % reduction noted in the alcohol-free arm. Complete ablation was achieved in 67 % of patients in the alcohol-free arm at both 6 and 12 months, whereas the alcohol group recorded complete ablation rates of 50 % and 75 % at 6 and 12 months, respectively. One patient in the alcohol arm developed acute pancreatitis (20 %) with no adverse events in the alcohol-free arm. Conclusions: This study revealed similar ablation rates between the alcohol ablation group and the alcohol-free arm and demonstrates the safety and feasibility of an alcohol-free ablation protocol. This pilot study suggests that alcohol may not be required for effective cyst ablation. PMID:27227122

    Objective: To compare the results from treating tropical pyomyositis through percutaneous drainage of abscesses versus open surgical drainage of abscesses, by means of a randomized prospective study. Methods: Twenty-five patients with tropical pyomyositis (Chiedozi grade II) were included in this study. They were randomized into two groups: group A (n = 13), treated with antibiotics and open drainage of the abscesses; and group B (n = 12), treated with antibiotics and percutaneous drainage of the abscesses. Results: The mean age was 35.3 years (± 19.2) in group A and 30.1 years (± 9) in group B (p = 0.41). There were eight female patients (61.5%) and five male patients (38.5%) in group A; in group B, three were female (25%) and nine were male (75%) (p = 0.11). Staphylococcus aureus was the microorganism most frequently found (72%). The mean hospital stay in group A was 12.7 days (± 2.3), and in group B, 10.6 days (± 1.6) (p = 0.01). The mean duration of antibiotic use in group A was 12.2 days (± 2.3), and in group B, 10.1 days (± 1.5) (p = 0.02). Conclusion: Percutaneous drainage of the abscesses, in association with antibiotic therapy, is an efficient treatment method for tropical pyomyositis grade II, with shorter antibiotic use and hospital stay for patients.

    The aim of the current study was to investigate the efficacy of greater occipital nerve (GON) block and bilateral superficial cervical plexuses (BSCP) blocks in alleviating postoperative occipital headache and posterior neck pain after thyroidectomy. This randomized prospective study consisted of 75 women undergoing total thyroidectomy. Patients were randomized into three groups: Group I (n = 25): patients receiving GON, Group II (n = 25): patients receiving bilateral (BSCP) blocks, and Group III (n = 25): patients receiving no block. Assessment of occipital headache, posterior neck, and incision site pains was made at 12 hours and 24 hours after extubation by Visual Analogue Scale (VAS). In comparison to Group III significantly fewer patients in Groups I and II experienced occipital headache at 12 (p = 0.006) and 24 hours (p = 0.005) and also posterior neck pain at 24 hours (p = 0.003). Mean VAS scores at 12 and 24 hours for occipital headache (p = 0.003 and p = 0.041) and posterior neck pain (p = 0.015 and p = 0.008) were significantly lower in Group I. The differences between Groups II and III were not significant except for the occipital headache at 12 hours. The efficacy of GON block is superior to BSCP blocks in alleviating postthyroidectomy occipital headache and posterior cervical pain. PMID:27034886

  11. A prospective, randomized, double-blind trial of the use of fibrin sealant for face lifts.

    Fibrin sealant imitates the final phase of the blood coagulation process. Fibrinogen is converted into fibrin on a tissue surface by the action of thrombin, which is then cross-linked by factor XIIIa, creating a mechanically stable fibrin network. This fibrin network is thought to reduce the amount of postoperative bleeding by sealing capillary vessels and allowing raw operative surfaces to adhere. The authors conducted a prospective, double-blind, randomized, controlled trial on the use of fibrin sealant in 20 consecutive patients undergoing bilateral face lifts by the same surgeon. Each patient was randomized for the use of fibrin sealant on either the right or the left side with the contralateral side acting as the control. Total drainage was recorded on each side for 24 hours before drains were removed. The age range of the patients in the trial (all of whom were women) was 44 to 70 years (mean, 55). The side treated with fibrin glue had a median drainage of 10 ml and the control side 30 ml. The Wilcoxon signed rank test shows a significant difference in drainage between sides (p = 0.002). The reduction in postoperative drainage could also reduce pain and bruising, increasing patient satisfaction with this procedure. The need for drains may also be obviated. PMID:11743409

    For the past two decades, the vast majority of vascular-access devices used in I.V. catheterization have been made of Teflon material. More recent developments in material science have produced the Vialon biomaterial currently used in the Insyte I.V. catheter. This prospective, randomized study compared the length of venous dwell time and rate of I.V.-related complications of Teflon peripheral I.V. catheters and Vialon peripheral I.V. catheters. The study population included only the most difficult peripheral I.V. access patients. Conditions of insertion, monitoring, and care were carefully controlled by the investigators. An alternate assignment scheme was used for randomization of eligible patients. Of 247 catheters evaluated over a six-week period in a 550-bed community tertiary care hospital, 191 were evaluable; of these, equivalent numbers were made of Vialon and Teflon. This investigation found that the incidence of phlebitis in the group receiving Vialon I.V. catheters was 36 percent lower than that of the group receiving Teflon I.V. catheters. PMID:2677289

    Objectives This study aims to assess the safety and efficacy of a biodegradable polymer-coated Rapamycin-Eluting Stent (Excel) used in conjunction with six-month dual antiplatelet therapy in daily practice. Background The polymeric material of cardiac stents has been reported to adversely affect the safety profile of the drug-eluting stents and is also suspected to cause serious long-term complications. It has been proposed that the biodegradable polymer coatings may reduce such late-stage adverse effects. Methods This is a prospective, multi-center registry of 654 patients from across 9 cardiology centers in India, who were enrolled and exclusively treated with Excel stents between February 2008 and May 2010. The recommended antiplatelet regimen included clopidogrel and aspirin for 6 months period, followed by lifelong aspirin therapy. Results The study population included 46.94% diabetics, 24.31% smokers, 48.93% hypertensives and 14.98% hyperlipidemics. The cumulative rates of major adverse cardiac events were 0.153% at discharge and 1.38% at 12 months. The mean percentage of stenosis was 88.24 ± 9.17% No events occurred between 6 and 12 months. Conclusions This multi-center registry study on “real world, all comers” has, thus, showed that EXCEL™ stent which is PLA-coated biodegradable Rapamycin-Eluting Stent exhibited high efficacy and safety profile in treatment of patients undergoing PCI as evidenced by significantly lower rates of MACE and no case of stent thrombosis. There was no event even after DAPT was discontinued after 6 months. PMID:25634407

    Purpose To establish a new clinical staging standard for nasopharyngeal carcinoma (NPC), based on intensity-modulated radiotherapy (IMRT), through a prospective multicenter clinical trial. Experiment Design 492 NPC patients were selected from six hospitals in the Guangxi Zhuang Autonomous Region, China from January 2006 to December 2009. Kaplan-Meier method was adopted to calculate survival rates. Log-rank test was used to compare survival differences. Results According to the seventh edition of the UICC/AJCC staging system, the differences between T1, T2 and T3 are not statistically significant, suggesting that T1, T2 and T3 could be combined as new T1. There were significant differences between all N stages except those of N3a and N3b, suggesting that N3a and N3b could be combined as new N3. Additionally, the overall survival (OS) curves of stages I, II, III and IVa were not significantly different. Therefore, we propose a new clinical NPC staging standard based on magnetic resonance imaging (MRI) and IMRT as T stage (including T1 and T2), N stage (including N0, N1, N2 and N3) and clinical staging includes I (T1N0M0), II (T1N1-2M0, T2N0M0), III (T2N1-2M0), IVa (TxN3M0) and IVb (TxNxM1). Recommended staging system performs better in risk difference and distribution balance. Furthermore, the differences in the 5-year curves of local relapse-free survival (LRFS), distant metastasis-free survival (DMFS), and OS were all statistically more significant than the seventh edition of the UICC/AJCC staging system. Conclusions Proposed staging system is more adaptable to IMRT and predicts the prognosis of NPC patients more accurately. PMID:26918446

    Background: Fertility is a priority for many young women with breast cancer. Women need to be informed about interventions to retain fertility before chemotherapy so as to make good quality decisions. This study aimed to prospectively evaluate the efficacy of a fertility-related decision aid (DA). Methods: A total of 120 newly diagnosed early-stage breast cancer patients from 19 Australian oncology clinics, aged 18–40 years and desired future fertility, were assessed on decisional conflict, knowledge, decision regret, and satisfaction about fertility-related treatment decisions. These were measured at baseline, 1 and 12 months, and were examined using linear mixed effects models. Results: Compared with usual care, women who received the DA had reduced decisional conflict (β=−1.51; 95%CI: −2.54 to 0.48; P=0.004) and improved knowledge (β=0.09; 95%CI: 0.01–0.16; P=0.02), after adjusting for education, desire for children and baseline uncertainty. The DA was associated with reduced decisional regret at 1 year (β=−3.73; 95%CI: −7.12 to −0.35; P=0.031), after adjusting for education. Women who received the DA were more satisfied with the information received on the impact of cancer treatment on fertility (P<0.001), fertility options (P=0.005), and rated it more helpful (P=0.002), than those who received standard care. Conclusion: These findings support widespread use of this DA shortly after diagnosis (before chemotherapy) among younger breast cancer patients who have not completed their families. PMID:22415294

    Background: Pressor response is a part of stress response caused by reflex sympathetic discharge due to direct laryngoscopy and tracheal intubation resulting in tachycardia, hypertension and arrhythmias. Both clonidine, and gabapentin administered orally can effectively blunt this detrimental hemodynamic response. Aim: To study the effect of oral clonidine to blunt the pressor response to direct laryngoscopy and to compare it with oral gabapentin. To observe for postoperative sedation and side effects if any. Settings and Design: Sixty patients of American Society of Anaesthesiologist Grade I and II scheduled for surgery under general anesthesia were considered in this prospective randomized double-blind study. They were randomly allocated into two groups of 30 each using computerized randomization. Materials and Methods: Group A was given oral clonidine 5 μg/kg and Group B was given oral gabapentin 800 mg. Both the drugs were given 90 min prior to surgery. Heart rate (HR) and blood pressure were monitored at baseline, 0, 1, 3, 5, 10, 15, and 30th min of laryngoscopy. Sedation was monitored by Ramsay Sedation Scale score and side effects were noted. Results: HR decreased in both groups at 0 and 1 min, increased at 3rd min and gradually decreased by 30th min. Statistically, significant difference was found between two groups at 1, 3, 5, 10, and 15th min (P < 0.05). Though there was no significant difference in systolic blood pressure, diastolic blood pressure and mean arterial pressure between the two groups, there was no rise in these parameters. Gabapentin produced more sedation than clonidine postoperatively, and few side effects were noted. Conclusion: Both oral clonidine and gabapentin are effective in obtunding pressor response to direct laryngoscopy, clonidine being better in terms of controlling HR. Gabapentin produces more postoperative sedation than clonidine. PMID:26957684

    Background: In this study, we aimed to investigate the effectiveness of silver nitrate (SN) versus tetracycline in pleurodesis among patients with malignant pleural effusion (MPE). Methods: In this prospective randomized clinical trial, patients with unilateral MPE candidate for pleurodesis were enrolled. The patients randomly allocated in two groups for receiving 20 mL 0.5% SN or 2.5 g tetracycline diluted in 30 cc normal saline and 0.1% lidocaine, through the chest tube. Patients were followed-up immediately (during 24 h) and 1-month after the procedure for evaluating recurrence of the pleural effusion using chest radiograph. They were clinically evaluated for chest pain and/or dyspnea and fever using a questionnaire that completed by the surgeon. The results were compared with two groups. Results: During this trial, 50 patients with MPE candidate for pleurodesis were selected and randomized into two interventional groups (25 patients in each group). Immediate and late recurrence of pleural effusion after pleurodesis were similar in two groups (P > 0.05). All patients in tetracycline group had fever and chest pain, but in SN group fever and chest pain were reported in 3 (12%) and 12 (48%) of patients, respectively (P < 0.05). Conclusion: SN is at least as effective as tetracycline for MPE treatment. In addition, its side effects were lower than tetracycline. Other advantages of SN are its low cost, availability, and safety. For more accurate results, it is recommended to design further trials with larger sample size and with lower doses of both SN and tetracycline. PMID:26605217

    OBJECTIVE: Surgeons have postulated on numerous occasions that cancer resection may participate in the dissemination of a malignancy. This randomized trial sought to determine whether a large volume of chemotherapy solution used perioperatively to flood the peritoneal cavity could eliminate microscopic residual disease and thereby improve survival of patients with gastric cancer. SUMMARY BACKGROUND DATA: Surgical treatment failures in patients with gastric cancer are confined to the abdomen in most patients. Resection site and peritoneal surface spread, along with liver metastases, are the most common areas of recurrence. Survival and quality of life of patients with gastric cancer would be improved if disease progression at these anatomic sites was reduced. METHODS: In a prospective randomized trial of 248 patients, intraperitoneal mitomycin C on day 1 and intraperitoneal 5-fluorouracil on days 2 through 5 were administered after gastric cancer resection. Patients who were thought to have stage II or stage III disease were randomized after resection to surgery alone versus surgery plus early postoperative intraperitoneal chemotherapy. After final pathologic examinations, there were 39 patients with stage I, 50 with stage II 95 with stage III, and 64 with resected stage IV cancer. RESULTS: The 5-year survival of the surgery-only group was 29.3%, and the surgery-plus-intraperitoneal chemotherapy group was 38.7% (p = 0.219). In a subset analysis, the patients with stage I, stage II, and stage IV disease showed no statistically significant difference in survival. The 5-year survival rate of patients with stage III disease who underwent surgery only was 18.4% versus a survival rate of 49.1% for patients who underwent surgery plus intraperitoneal chemotherapy (p = 0.011). CONCLUSIONS: In a subset analysis, patients with stage III gastric cancer have shown a statistically significant improvement in survival when treated with perioperative intraperitoneal chemotherapy

    Study question What are the diagnostic yield and accuracy of early computed tomography (CT) angiography followed by magnetic resonance imaging/angiography (MRI/MRA) and digital subtraction angiography (DSA) in patients with non-traumatic intracerebral haemorrhage? Methods This prospective diagnostic study enrolled 298 adults (18-70 years) treated in 22 hospitals in the Netherlands over six years. CT angiography was performed within seven days of haemorrhage. If the result was negative, MRI/MRA was performed four to eight weeks later. DSA was performed when the CT angiography or MRI/MRA results were inconclusive or negative. The main outcome was a macrovascular cause, including arteriovenous malformation, aneurysm, dural arteriovenous fistula, and cavernoma. Three blinded neuroradiologists independently evaluated the images for macrovascular causes of haemorrhage. The reference standard was the best available evidence from all findings during one year’s follow-up. Study answer and limitations A macrovascular cause was identified in 69 patients (23%). 291 patients (98%) underwent CT angiography; 214 with a negative result underwent additional MRI/MRA and 97 with a negative result for both CT angiography and MRI/MRA underwent DSA. Early CT angiography detected 51 macrovascular causes (yield 17%, 95% confidence interval 13% to 22%). CT angiography with MRI/MRA identified two additional macrovascular causes (18%, 14% to 23%) and these modalities combined with DSA another 15 (23%, 18% to 28%). This last extensive strategy failed to detect a cavernoma, which was identified on MRI during follow-up (reference strategy). The positive predictive value of CT angiography was 72% (60% to 82%), of additional MRI/MRA was 35% (14% to 62%), and of additional DSA was 100% (75% to 100%). None of the patients experienced complications with CT angiography or MRI/MRA; 0.6% of patients who underwent DSA experienced permanent sequelae. Not all patients with negative CT angiography and

    Purpose: The prognosis for children with central nervous system primitive neuroectodermal tumor (CNS-PNET) or pinealoblastoma is still unsatisfactory. Here we report the results of patients between 4 and 21 years of age with nonmetastatic CNS-PNET or pinealoblastoma diagnosed from January 2001 to December 2005 and treated in the prospective GPOH-trial P-HIT 2000-AB4. Methods and Materials: After surgery, children received hyperfractionated radiation therapy (36 Gy to the craniospinal axis, 68 Gy to the tumor region, and 72 Gy to any residual tumor, fractionated at 2 × 1 Gy per day 5 days per week) accompanied by weekly intravenous administration of vincristine and followed by 8 cycles of maintenance chemotherapy (lomustine, cisplatin, and vincristine). Results: Twenty-six patients (15 with CNS-PNET; 11 with pinealoblastoma) were included. Median age at diagnosis was 11.5 years old (range, 4.0-20.7 years). Gross total tumor resection was achieved in 6 and partial resection in 16 patients (indistinct, 4 patients). Median follow-up of the 15 surviving patients was 7.0 years (range, 5.2-10.0 years). The combined response rate to postoperative therapy was 17 of 20 (85%). Eleven of 26 patients (42%; 7 of 15 with CNS-PNET; 4 of 11 with pinealoblastoma) showed tumor progression or relapse at a median time of 1.3 years (range, 0.5-1.9 years). Five-year progression-free and overall survival rates (±standard error [SE]) were each 58% (±10%) for the entire cohort: CNS-PNET was 53% (±13); pinealoblastoma was 64% (±15%; P=.524 and P=.627, respectively). Conclusions: Postoperative hyperfractionated radiation therapy with local dose escalation followed by maintenance chemotherapy was feasible without major acute toxicity. Survival rates are comparable to those of a few other recent studies but superior to those of most other series, including the previous trial, HIT 1991.

    Background A major challenge in the control of human African trypanosomiasis (HAT) is lack of reliable diagnostic tests that are rapid and easy to use in remote areas where the disease occurs. In Trypanosoma brucei gambiense HAT, the Card Agglutination Test for Trypanosomiasis (CATT) has been the reference screening test since 1978, usually on whole blood, but also in a 1/8 dilution (CATT 1/8) to enhance specificity. However, the CATT is not available in a single format, requires a cold chain for storage, and uses equipment that requires electricity. A solution to these challenges has been provided by rapid diagnostic tests (RDT), which have recently become available. A prototype immunochromatographic test, the SD BIOLINE HAT, based on two native trypanosomal antigens (VSG LiTat 1.3 and VSG LiTat 1.5) has been developed. We carried out a non-inferiority study comparing this prototype to the CATT 1/8 in field settings. Methodology/Principal Findings The prototype SD BIOLINE HAT, the CATT Whole Blood and CATT 1/8 were systematically applied on fresh blood samples obtained from 14,818 subjects, who were prospectively enrolled through active and passive screening in clinical studies in three endemic countries of central Africa: Angola, the Democratic Republic of the Congo and the Central African Republic. One hundred and forty nine HAT cases were confirmed by parasitology. The sensitivity and specificity of the prototype SD BIOLINE HAT was 89.26% (95% confidence interval (CI) = 83.27–93.28) and 94.58% (95% CI = 94.20–94.94) respectively. The sensitivity and specificity of the CATT on whole blood were 93.96% (95% CI = 88.92–96.79) and 95.91% (95% CI = 95.58–96.22), and of the CATT 1/8 were 89.26% (95% CI = 83.27–93.28) and 98.88% (95% CI = 98.70–99.04) respectively. Conclusion/Significance After further optimization, the prototype SD BIOLINE HAT could become an alternative to current screening methods in primary healthcare settings in remote, resource

    Background. Empirical therapy with antisecretory agents like PPIs and H2RAs has long been the traditional approach in the initial management of uninvestigated dyspepsia. Aim. The objective of the study was to examine relief of dyspepsia with lafutidine, a second-generation H2-RA, and rabeprazole and to compare their efficacy. Methods. This was a randomized, open, comparative trial in adult uninvestigated dyspeptic patients, who had at least moderate severity of symptoms, defined as a score of ≥4 on a 7-point global overall symptom (GOS) scale, and were randomized to receive once daily either lafutidine 10 mg or rabeprazole 20 mg for 4 weeks. Results. A total of 236 patients were enrolled, out of which 194 patients were included in the analysis. At the end of week 4, a significant difference was observed for symptom relief (lafutidine 89.90% versus rabeprazole 65.26%, P < .01) and symptom resolution (lafutidine 70.71% versus rabeprazole 25.26%, P < .01). Both the drugs were well tolerated. Conclusion. Both lafutidine and rabeprazole provide symptom relief in patients with heartburn-dominant uninvestigated dyspepsia. The present study confirms the appropriateness of lafutidine as an empiric treatment and superior efficacy for primary care practice patients with dyspepsia. PMID:21687618

  3. Web-based screening and brief intervention for poly-drug use among teenagers: study protocol of a multicentre two-arm randomized controlled trial

    PubMed Central

    2012-01-01

    Background Mid to late adolescence is characterised by a vulnerability to problematic substance use since the consumption of alcohol and illicit drugs is frequently initiated and increased in this life period. While the detrimental long- and short-term effects of problematic consumption patterns in adolescence pose a major public health concern, current prevention programs targeting alcohol- and other substance-using adolescents are scarce. The study described in this protocol will test the effectiveness of a web-based brief intervention aimed at reducing problematic alcohol use and promoting abstinence from illegal drugs in adolescents with risky substance use aged 16 to 18 years old in four EU-countries. Methods/design To determine the effectiveness of our web-BI, we apply a two-arm randomized controlled trial (RCT) study design, with baseline assessment at study entry and a three month follow-up assessment. Adolescents aged 16 to 18 years from Belgium, the Czech Republic, Germany, and Sweden will be randomly assigned to either the fully electronically delivered brief intervention group (N = 400) or an assessment only control group (N = 400) depending on their screening for risky substance use (using the CRAFFT). Recruitment, informed consent, randomization, intervention and follow-up will be implemented online. Primary outcomes are reductions in frequency and quantity of use of alcohol and drugs other than alcohol over a 30 day period, as well as consumption per typical occasion. Secondary outcomes concern changes in substance use related cognitions including the constructs of the Theory of Planned Behaviour, implementation intentions, and stages of change. Moreover the study addresses a number of moderator variables, including age of first use, general psychopathology and quality of parent–child relationship. Discussion The trial is expected to contribute to the growing literature on theory- and web-based brief interventions for adolescents. We will

    Purpose This study aimed to compare the safety and efficacy of tamsulosin and tadalafil as medical expulsive therapy for distal ureteral stones. Materials and Methods This prospective randomized study was conducted at the Department of Urology of Bir Hospital over a period of 12 months in patients with distal ureteral stones sized 5 to 10 mm. Patients were randomly divided into 2 groups: group A received tamsulosin 0.4 mg and group B received tadalafil 10 mg at bedtime for 2 weeks. Stone expulsion rate, number of ureteric colic episodes and pain score, analgesic requirements, and adverse drug effects were noted in both groups. Statistical analyses were performed by using Student t-test and chi-square test. Results Altogether 85 patients, 41 in group A and 44 in group B, were enrolled in the study. The patients' average age was 31.72±12.63 years, and the male-to-female ratio was 1.5:1. Demographic profiles, stone size, and baseline investigations were comparable between the 2 groups. The stone expulsion rate was significantly higher in the tadalafil group than in the tamsulosin group (84.1% vs. 61.0%, p=0.017). Although the occurrence of side effects was higher with tadalafil, this difference was not significant (p=0.099). There were no serious adverse effects. Conclusions Tadalafil has a significantly higher stone expulsion rate than tamsulosin when used as a medical expulsive therapy for distal ureteral stones sized 5–10 mm. Both drugs are safe, effective, and well tolerated with minor side effects. PMID:27617317

    Noninvasive positive pressure ventilation has been found to be efficacious in the setting of acute respiratory failure, specifically in chronic obstructive pulmonary disease exacerbations. Its use in congestive heart failure (CHF) is less well established. Additionally, it has been reported that there is an increase in acute myocardial infarction (AMI) rate with the use of bilevel positive pressure ventilation (BiPAP) in CHF patients. This study examined whether BiPAP decreases the intubation rate or improves cardiopulmonary parameters in severe CHF patients compared to high flow O(2) by mask (MASK), and whether there is an increase in AMI rate with the use of BiPAP. A prospective, randomized clinical trial at a county hospital teaching Emergency Department was conducted by enrolling 38 patients who were in severe CHF. Patients were randomized to receive either BiPAP or MASK in addition to adjunct therapy. Age and gender were not different between the groups. Heart rate, systolic blood pressure, diastolic blood pressure, respiratory rate, and pulse oximetry all showed no significant difference in change over time between groups, but there was a significant change over time within groups. Arterial pH, pCO(2), and pO(2) also showed no significant difference in change over time between groups, but there was a significant change over time within groups. The intubation rate for BiPAP was 23.8% (5) vs. MASK at 41.2% (7). The AMI rate was 19% (4) in the BiPAP group and 29.4% (5) in the MASK group. No true differences were detected between groups for increased oxygenation or a reduction in intubation rate. An increase in AMI rate with BiPAP was not found in this study as previously reported. This study provides support for a larger clinical trial assessing the safety and efficacy of BiPAP in acute CHF. PMID:11728761

    Purpose To compare surgical efficiency and multiple early clinical outcome variables in eyes undergoing phacoemulsification using either transversal or torsional ultrasound systems. Setting Assil Eye Institute, Beverly Hills, CA, USA. Design Prospective, randomized, clinician-masked, contralaterally controlled single-center evaluation. Patients and methods Patients seeking cataract removal in both eyes with implantation of multifocal intraocular lenses were randomly assigned to one of two treatment rooms for phacoemulsification with either a transverse ultrasound system or torsional handpiece system. The contralateral eye was treated at a later date with the alternate device. A total of 54 eyes of 27 patients having similar degrees of cataract, astigmatism, and visual potential were included. All operative data were collected for analysis, and patients were followed for 3 months after surgery. Results Similar visual acuity was reported at all postoperative visits between the two groups. Mean phacoemulsification time and total power required were both significantly lower with the transverse system than with the torsional technique (P<0.05 for both). Similarly, mean total balanced salt solution used was significantly less with the transverse system vs torsional (P<0.05). Postoperative safety demonstrated significantly lower endothelial cell loss at 1 day and 1 month (P<0.05) with transverse vs torsional. Macular swelling was less at 1 week, 1 month, and 3 months with transverse vs torsional, although the difference did not achieve significance (P=0.1) at any single time point. Clinically detectable corneal edema was reported less frequently at all postoperative time points with the transverse system. Conclusion The transverse ultrasound system was found to be possibly associated with less balanced salt-solution use, less phacoemulsification time, and less power required than the torsional phaco system. Postoperative data suggested that improved phaco efficiency may

The current study aimed to evaluate whether increasing the level of dissolved oxygen by Hyperbaric Oxygen Therapy (HBOT) could activate neuroplasticity in patients with chronic neurologic deficiencies due to stroke. Methods and Findings A prospective, randomized, controlled trial including 74 patients (15 were excluded). All participants suffered a stroke 6–36 months prior to inclusion and had at least one motor dysfunction. After inclusion, patients were randomly assigned to "treated" or "cross" groups. Brain activity was assessed by SPECT imaging; neurologic functions were evaluated by NIHSS, ADL, and life quality. Patients in the treated group were evaluated twice: at baseline and after 40 HBOT sessions. Patients in the cross group were evaluated three times: at baseline, after a 2-month control period of no treatment, and after subsequent 2-months of 40 HBOT sessions. HBOT protocol: Two months of 40 sessions (5 days/week), 90 minutes each, 100% oxygen at 2 ATA. We found that the neurological functions and life quality of all patients in both groups were significantly improved following the HBOT sessions while no improvement was found during the control period of the patients in the cross group. Results of SPECT imaging were well correlated with clinical improvement. Elevated brain activity was detected mostly in regions of live cells (as confirmed by CT) with low activity (based on SPECT) – regions of noticeable discrepancy between anatomy and physiology. Conclusions The results indicate that HBOT can lead to significant neurological improvements in post stroke patients even at chronic late stages. The observed clinical improvements imply that neuroplasticity can still be activated long after damage onset in regions where there is a brain SPECT/CT (anatomy/physiology) mismatch.

    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

    The oncogenic effects of radiation are well-established. Osteosarcomas and fibrosarcomas are the two most common histologic types of secondary sarcoma. In this article a case of postradiation osteosarcoma is presented in which four discrete foci of sarcomatous transformation have occurred in the tibia and fibula after irradiation for a rhabdomyosarcoma of the calf 8 years earlier. A review of the literature reveals no similar case. Although synchronous, multifocal osteosarcoma without prior radiation has been described, this case differs in clinical, radiographic, and pathologic features; it best fits the description of postradiation multicentric osteosarcoma.

    This randomized, double-blind, placebo-controlled study evaluated whether lamivudine given during late pregnancy can reduce hepatitis B virus (HBV) perinatal transmission in highly viraemic mothers. Mothers were randomized to either lamivudine 100 mg or placebo from week 32 of gestation to week 4 postpartum. At birth, infants received recombinant HBV vaccine with or without HBIg and were followed until week 52. One hundred and fifty mothers, with a gestational age of 26-30 weeks and serum HBV DNA >1000 MEq/mL (bDNA assay), were treated. A total of 141 infants received immunoprophylaxis at birth. In lamivudine-treated mothers, 56 infants received vaccine + HBIg (lamivudine + vaccine + HBIg) and 26 infants received vaccine (lamivudine + vaccine). In placebo-treated mothers, 59 infants received vaccine + HBIg (placebo + vaccine + HBIg). At week 52, in the primary analyses where missing data was counted as failures, infants in the lamivudine + vaccine + HBIg group had a significant decrease in incidence of HBsAg seropositivity (10/56, 18%vs 23/59, 39%; P = 0.014) and in detectable HBV DNA (11/56, 20%vs 27/59, 46%; P = 0.003) compared to infants in the placebo + vaccine + HBIg group. Sensitivity analyses to evaluate the impact of missing data at week 52 resulting from a high dropout rate (13% in the lamivudine + vaccine + HBIg group and 31% in the placebo + vaccine + HBIg group) remained consistent with the primary analysis in that lower transmission rates were still observed in the infants of lamivudine-treated mothers, but the differences were not statistically significant. No safety concerns were noted in the lamivudine-treated mothers or their infants. Results of this study suggest that lamivudine reduced HBV transmission from highly viraemic mothers to their infants who received passive/active immunization. PMID:19175878

  11. Pre-Study protocol MagPEP: a multicentre randomized controlled trial of magnesium sulphate in the prevention of post-ERCP pancreatitis

    PubMed Central

    2013-01-01

    Background Acute pancreatitis is the most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). In spite of continuing research, no pharmacologic agent capable of effectively reducing the incidence of ERCP-induced pancreatitis has found its way into clinical practise. A number of experimental studies suggest that intrapancreatic calcium concentrations play an important role in the initiation of intracellular protease activation, an initiating step in the course of acute pancreatitis. Magnesium can act as a calcium-antagonist and counteracts effects in calcium signalling. It can thereby attenuate the intracellular activation of proteolytic digestive enzymes in the pancreas and reduces the severity of experimental pancreatitis when administered either intravenously or as a food supplement. Methods We designed a randomized, double-blind, placebo-controlled phase III study to test whether the administration of intravenous magnesium sulphate before and after ERCP reduces the incidence and the severity of post-ERCP pancreatitis. A total of 502 adult patients with a medical indication for ERCP are to be randomized to receive either 4930 mg magnesium sulphate (= 20 mmol magnesium) or placebo 60 min before and 6 hours after ERCP. The incidence of clinical post-ERCP pancreatitis, hyperlipasemia, pain levels, use of analgetics and length of hospital stay will be evaluated. Conclusions If magnesium sulphate is found to be effective in preventing post-ERCP pancreatitis, this inexpensive agent with limited adverse effects could be used as a routine pharmacological prophylaxis.

    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. PMID:26962506

    Purpose We aimed to investigate the cardiopulmonary effects of pressurized cement insertion in elderly patients undergoing cemented hip hemiarthroplasty. Materials and Methods We conducted a randomized prospective study on elderly patients undergoing cemented hip hemiarthroplasty. Patients were divided into pressurized and non-pressurized groups based on the pressure application during cement insertion. We measured mean arterial blood pressure (MAP), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), arterial blood gases and serotonin concentration in blood. These variables were measured before bone cement insertion, and 3 and 5 minute after insertion. They were also measured immediately and 15 minutes after reduction. Results In cemented hip hemiarthroplasty, there were no significant change in MAP (P=0.92), SBP (P=0.85), DBP (P=0.98), HR (P=0.97) and serotonin concentration over time. There were no statistically significant difference between the two groups in MAP, SBP, DBP, HR, PO2, PaCO2, SaO2 and serotonin concentration, though three minutes after cement insertion, both groups showed decreases in SBP, DBP and MBP. Conclusion The pressurization method in cemented hip hemiarthroplasty was not found to be related with development of bone cement syndromes in elderly patients.

    We have undertaken a prospective, randomized comparison of the superficially similar techniques of interpleural and paravertebral (extrapleural) analgesia in 53 patients undergoing posterolateral thoracotomy. Local anaesthetic placed anterior to the superior costotransverse ligament and posterior to the parietal pleura produces a paravertebral block and instilled between the parietal and visceral pleurae produces an interpleural block. Patients received preoperative and postoperative continuous bupivacaine paravertebral blocks in group 1 and interpleural blocks in group 2. Premedication comprised diclofenac and morphine, and after operation all patients had regular diclofenac and patient-controlled morphine (PCM). Analgesia was assessed by visual analogue pain scores (VAS), PCM requirements, ratio of preoperative to postoperative spirometric values (PFT), rates of postoperative respiratory morbidity (PORM) and hospital stay, all recorded by blinded observers. Eight patients were withdrawn and data from 45 patients were analysed. Patient characteristics, surgery, VAS scores and PCM use were similar in both groups. PFT were significantly better (P = 0.03-0.0001) in group 1, and PORM was lower and hospital stay approximately 1 day less in this group. Five patients in group 2 became temporarily confused, probably because of bupivacaine toxicity (P = 0.02). We conclude that bupivacaine deposited paravertebrally produced greater preservation of lung function and fewer side effects than bupivacaine administered interpleurally. PMID:7488477

    This trial prospectively compares two methods of percutaneous tracheostomy, both routinely used in ICU: the Ciaglia progressive dilational tracheostomy and the Griggs forceps dilational tracheostomy. One hundred patients were randomized using a single-blinded envelope method to receive progressive or forceps percutaneous tracheostomy performed at the bedside. Operative time, the occurrence of hypoxaemia or hypercapnia and complications were recorded. The progressive technique took longer than the forceps technique (median 7 (range 2-26) vs. 4 (1-16) minutes, P = 0.0005). Hypercapnia occurred in both groups but was more marked with the progressive technique (56 (16) vs. 49 (13) mmHg, P = 0.0082). Minor complications (minor bleeding, transient hypoxaemia, damage to posterior tracheal wall without emphysema) were also more frequent with the progressive technique (31 vs. 9 complications, P < 0.0001). Six major complications occurred with the progressive technique, none with the forceps technique (P = 0.0085): tension pneumothorax, posterior tracheal wall injury with subcutaneous emphysema, loss of airway with hypoxaemia, loss of stoma with impossible re-catheterization, and two conversions to another technique. In conclusion, progressive dilational tracheostomy took longer, caused more hypercapnia and more minor and major difficulties than forceps dilational tracheostomy. PMID:16494150

    In a prospective, randomized study, laparoscopic (n = 20) and Lichtenstein (n = 18) inguinal hernia repairs were compared in relation to operative time, operative costs, hospital stay, postoperative pain, return to work, patient satisfaction, complications, and total costs. All the operations were performed with the patient under general anesthesia. The median operative times in the laparoscopic and Lichtenstein groups were 71.5 (range, 43-140) and 45 (16-83) min, respectively (p < 0.001). Postoperative pain and use of analgesics was less in the laparoscopic group. The median time to return to work was 14 (8-26) days in the laparoscopic group and 19 (5-40) days in the Lichtenstein group. More complications occurred in the Lichtenstein group. The median of the operative costs, in U.S. dollars, was $1,395 and $878, respectively, and the median total costs (including community expenses resulting from lost workdays) were $4,796 in the laparoscopic and $5,320 in the Lichtenstein groups.

    Context: Polycystic ovary syndrome (PCOS) is characterized by ovarian dysfunction and hyperandrogenism; it is also associated with increased cardiovascular risks such as adverse lipid profile and endothelial dysfunction. Metformin and, more recently, statins have been shown to improve endocrine and metabolic aspects of PCOS. Objective: The aim of the study was to compare effects of simvastatin and metformin on PCOS. Design: In a prospective trial, women with PCOS (n = 136) were randomized to simvastatin (S), metformin (M), or simvastatin plus metformin (SM) groups. Evaluations were performed at baseline and after 3 months. Setting: The study was conducted at an academic medical center. Primary Outcome: The change of serum total testosterone was measured. Results: The study was completed by 113 subjects. Total testosterone decreased significantly and comparably in all groups: by 17.1, 13.6, and 15.1%, respectively, in the S, M, and SM groups. Significant decreases were also observed in all groups with respect to body mass index, C-reactive protein, and soluble vascular cell adhesion molecule-1. DHEAS declined significantly only in the S group. None of the treatments were associated with significant changes in LH or FSH. Total cholesterol and low-density lipoprotein cholesterol significantly declined only in S and SM groups. Conclusions: Simvastatin treatment was superior to metformin alone, whereas a combination of simvastatin and metformin was not significantly superior to simvastatin alone. PMID:19890022

    Thirty patients with breast cancer were prospectively randomized into case and control groups receiving 40 mg famotidine preoperatively for 10-14 days and routine premedication, respectively. Surgical specimens were evaluated objectively for tumor infiltrating lymphocytes in the center and in the periphery of the tumor along with evaluation of metastatic lymph nodes for reactive changes. Ten famotidine-treated cases (67%) showed significant lymphocytic infiltration in the center compared to 4 controls (27%) (p = 0.03). Eleven cases (77%) had significant lymphocytic infiltration in the periphery (p = 0.03) compared to 5 controls (33%). Considering both sites, lymphocytic response was significant in 9 (60%) cases as opposed to only 3 (20%) controls (p = 0.03). This response did not correlate with the stage, grade of tumor or menopausal status of patients in either group. Seventy-eight percent (78%) of the cases showed significant reactive changes in the metastatic lymph nodes as compared to 22% in controls (p < 0.01). This study suggests that famotidine enhances tumor infiltrating lymphocytes in breast cancer and might have potential as an immunomodulator. A larger confirmatory study is suggested. PMID:12234028

    A prospective randomized comparative study was conducted to compare open reduction and internal fixation of displaced fractures (>2mm) via intraoral approach with application of a single monocortical miniplate according to Champy's ideal line of osteosynthesis (group A) versus an extraoral approach with application of an inferior border plate with at least two holes (bicortical screws) on either side of the fracture line (group B). Clinical and radiographic assessment was done preoperatively, immediately postoperative, and at 1, 4, and 12 weeks of follow-up. Parametric and non-parametric data were evaluated by independent samples t-test and χ(2) analysis, respectively; P<0.05 was considered statistically significant. There was no significant difference between the two groups with regard to complication rates, although functional outcomes including pain (visual analogue scale score) at the 1-week follow-up and inter-incisal mouth opening at the 12-week follow-up were found to be better in group B. On radiographic assessment, the inferior border was better aligned in group B than in group A, with no superior border distraction in group B. The duration of surgery was shorter in group B, and this was considered to be the easier approach for fixation of the device as assessed by the surgeons. PMID:24636170

    A prospective, randomized, double-blind clinical study was performed to determined the efficacy of short-term (24 hr) perioperative antibiotics in preventing septic complications after emergency appendectomy for nonperforated appendicitis. The patients were stratified into three clinical arms: Group I (placebo, n = 45), Group II (cefamandole, n = 46) and Group III (cefamandole plus carbenicillin, n = 45). The three groups of patients were similar in regard to age, sex, duration of operation and pathologic classification of the appendix. The overall incidence of infection in the study was 5.1%. The infection rates in Groups II (2.2%) and III (0%) were significantly lower than Group I (placebo) (13.3%), (p less than 0.05). No difference was observed between cefamandole alone and cefamandole plus carbenicillin. Average postoperative hospital days per patient for each group was: Group I - 3.8 days; Group II - 2.9 days; Group III - 3.1 days. Cost analysis of hospitalization including cost of prophylactic antibiotics revealed a $247.99 per patient saving for Group II versus Group I and $95.53 for Group III versus Group I. Systemic prophylactic antibiotics can successfully reduce septic complications after appendectomy for nonperforated appendicitis, and a single drug (cefamandole) directed at the facultative pathogens is as effective as double drug therapy, which includes specific anaerobic coverage.

    Objective: This study had the objective of prospectively comparing transverse fixation (Cross-Pin™) with extracortical fixation (EZLoc™) for the femur, in surgical reconstruction of the anterior cruciate ligament, from a clinical, biomechanical and functional point of view. Methods: Between April 2007 and November 2009, 50 patients with acute or chronic anterior cruciate ligament injuries underwent arthroscopic reconstruction using the homologous flexor tendons (gracilis and semitendinosus). Randomization of the femoral fixation method was done by means of a draw at the time of the procedure. Patients were excluded if they presented multiple ligament lesions, fractures, previous surgery, autoimmune disease and impairment of the contralateral knee. The Lysholm scale, SF36 quality-of-life questionnaire and KT1000™ arthrometer were used. Results: After a mean follow-up of 18.1 months, there were no statistically significant differences between the groups regarding the Lysholm scale and KT1000™ measurements. However, the SF36 questionnaire showed a statistical difference such that transverse fixation was superior regarding pain and vitality. Conclusion: Both techniques were shown to be efficient for transfemoral fixation, but with almost no statistically significant difference between them. We believe that new studies will be necessary for better understanding of these differences. PMID:27042646

    Purpose To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.

    Background: For patients receiving external beam radiation therapy (EBRT) after radical prostatectomy as adjuvant treatment or patients receiving EBRT as definitive treatment, partial irradiation of the urinary bladder is common. Many of such patients experience some degree of radiation-induced cystitis during or after EBRT. There is currently no efficient treatment for preventing radiation cystitis. Objective: The aim of this study was to evaluate the effectiveness of one of the safe mucilaginous herbs (Malva) in preventing radiation-induced dysuria in patients who are undergoing EBRT for prostate cancer. Methods: From April 2013 to August 2014, 68 patients were randomized into two groups using four block randomization, 34 to the drug (Malva) group and 34 to the placebo group. Of the 68 patients who began the study, 60 completed it. They were instructed to use the medication, i.e., Malva or the placebo, three times a day for six weeks. They were followed by a physician every two weeks for eight weeks, and urinary function was assessed in each visit by asking questions based on the Visual Prostate Symptom Score (VPSS) and a dysuria severity score. The changes in the VPSS and dysuria severity score between baseline and each follow-up visit were compared between the two groups in the study using repeated measures analysis of variance (ANOVA) and t-tests. Results: The median age of the 68 patients was 66. Twenty-one of 27 patients in the control group (77.7%) suffered from dysuria, while dysuria was detected in 23 of 33 patients (69.6%) who received Malva (odds ratio=2.70 for dysuria). After two weeks, four weeks, and six weeks of treatment with Malva, dysuria due to EBRT was milder in the treatment group than in the control group, and the differences were statistically significant (p = 0.005, p = 0.004, p = 0.001, respectively). Conclusion: To the best of our knowledge, our study is the first study to assess the protective effect of a mucilaginous herb (Malva

    Non-small cell lung cancer (NSCLC) is associated with IL-2-dependent cell-mediated immunodeficiency. As IL-2 is the main lymphocyte growth factor, a phase III randomized multicenter trial was conducted to evaluate the impact of subcutaneous low-dose IL-2 added to standard chemotherapy (CT) on overall survival (OS) in advanced NSCLC patients. Patients (n=241) with histologically confirmed stage IIIb or IV non-operable NSCLC underwent stratified randomization on the basis of center, ECOG PS, stage of disease and percentage of weight loss. Patients received gemcitabine (1000 mg/m2) on days 1 and 8 + cisplatin (100 mg/m2) on day 2 every 21 days for a maximum of 6 cycles [chemotherapy (CT) arm]. In the CT+IL-2 arm, patients also received low-dose subcutaneous IL-2 3,000,000 IU/die on days 3-5, 9-11, 15-17. The study had 90% power to detect a 20% absolute increase in 1-year OS with 118 patients/arm. An overall response (OR) rate of 12.8% (14% in the CT+IL-2 arm and 11.4% in CT arm) was observed. Stable disease was 70 and 66.7%, and progressive disease 16 and 21.8% in the CT+IL-2 and CT arms, respectively. No differences in response were found in any subgroup analysis. At a median follow-up of 32 months, 1-year OS was 45% for the CT+IL-2 arm vs. 51% for the CT arm (p=0.456 log-rank). Median progression-free survival was 6.6 months in the CT+IL-2 arm vs. 6.9 months in the CT arm (p=0.573, log-rank). A higher number of grade 4 toxicities were reported with CT+IL-2. The most common grade ≥3 adverse events were gastrointestinal toxicity (mainly nausea and diarrhea) and myelosuppression. No relevant differences in clinical outcome were observed from the addition of IL-2 to CT. Future studies investigating the role of T-regulators in chemoimmunotherapeutic regimens could be performed.

    Objective To evaluate the efficacy and safety of an investigational fibrin sealant (FS) in a randomized prospective, partially blinded, controlled, multicenter trial. Summary Background Data Upper extremity vascular access surgery using polytetrafluorethylene (PTFE) graft placement for dialysis was chosen as a reproducible, clinically relevant model for evaluating the usefulness of FS. The FS consisted of pooled human fibrinogen (60 mg/mL) and thrombin (500 NIH U/mL). Time to hemostasis was measured, and adverse events were monitored. Methods Consenting adult patients (n = 48) undergoing placement of a standard PTFE graft were randomized in a 2:1:1 ratio to the treatment group using FS (ZLB Bioplasma AG, Bern, Switzerland), oxidized regenerated cellulose (Surgicel, Johnson & Johnson, New Brunswick, NJ), or pressure. Patients received heparin (3,000 IU IVP) before placement of vascular clamps. If the treatment was FS, clamps were left in place for 120 seconds after the application of study material to permit polymerization. If treatment was Surgicel, clamps were left in place until the agent had been applied according to manufacturer’s instructions. If the treatment was pressure, clamps were released as soon as the investigator was ready to apply compression. Immediately after release of the last clamp, the arterial and venous suture lines were evaluated for bleeding. The time to hemostasis at both the venous and arterial sites was recorded. Results Significant (P ≤ .005) reduction in time to hemostasis was achieved in the FS group. Thirteen (54.2%) patients randomized to FS experienced immediate hemostasis at both suture lines following clamp removal compared to no patients using Surgicel or pressure. Only one patient (7.1%) in the Surgicel group and no patients in the pressure group experienced hemostasis at 120 seconds from clamp removal, compared to 13 (54.2%) patients for FS. Adverse events were comparable in all groups. There were no seroconversions

    Standardized aqueous mistletoe extracts have been applied to cancer patients for several decades as complementary medicine. A multicentric, randomized, open, prospective clinical trial was conducted in three oncological centers in the People's Republic of China in Bejing, Shenyang and Tianjin. Following the guidelines of "Good Clinical Practice" (GCP) this study was performed to get information on efficacy safety and side-effects of the standardized mistletoe extract (sME). Two hundred and thirty-three patients with breast (n=68), ovarian (n=71) and non-small cell lung cancer (NSCLC; n=94) were enrolled into this study. Two hundred and twenty-four patients fulfilled the requirements for final analysis (n=115 treated with sME HELIXOR A; n=109 comprising the control group being treated with the approved immunomodulating phytopharmacon Lentinan). All patients were provided with standard tumor-destructive treatment schedules and complementarily treated with sME or Lentinan during chemotherapy according to treatment protocol. Biometrically, the patients of the control and sME treatment group were comparable regarding distribution, clinical classification (WHO) and treatment protocols. Analysis was performed according to the "Intention to treat principle". Quality of life (QoL) was significantly (p<0.05) improved for patients who were complementarily treated with sME, as determined by the questionnaires FLIC (Functional Living Index-Cancer), TCM (Traditional Chinese Medicine Index) and the KPI (Karnofsky Performance Index) in comparison to the control group. Additionally, the occurrence of adverse events (AEs) was less frequent in the sME than in the control group (total number of AEs 52 versus 90 and number of serious AEs 5 versus 10 in study and control group, most of them due to chemotherapy). Only one serious AE was allocated to complementary treatment in each group (1 angioedema in sME group). All other side-effects of the sME (7 harmless local inflammatory

    In a double blind study, patients with operable carcinoma of the colon and the upper rectum, who have undergone a macroscopically complete resection of their tumor, were randomized to receive either (i) polyadenylic-polyuridylic acid (AU), one i.v. injection of 60 mg (in 50 ml of solution) once a week for 6 weeks, or (ii) a placebo (P) one i.v. injection of 50 ml of a saline solution with the same schedule. From January 1983 to December 1986, 288 patients were enrolled: 145 in AU group and 143 in P group. The main clinical and pathological characteristics were equally distributed throughout the two groups. There was a significant difference (P < 0.02) in the overall survival (OS) between the two groups, in favor of the P group. The 5-year OS rate was 68% (SD = 4%) in the AU group versus 81% (SD = 3%) in the P group. Thus, AU as a single adjuvant, appears to be ineffective and therefore has no indication in the treatment of colorectal carcinoma. PMID:1478293

    Surgical resection offers the best chance for cure for early stage non-small-cell lung cancer (NSCLC, stage I, II, IIIA), but the 5-year survival rates are only moderate, with systemic relapse being the major cause of death. Pre-operative (neo-adjuvant) chemotherapy has shown promise in small trials restricted to stage IIIA patients. We believe similar trials are now appropriate in all stages of operable lung cancer. A feasibility study was performed in 22 patients with early stage (IB, II, IIIA) resectable NSCLC; randomized to either three cycles of chemotherapy [mitomycin-C 8 mg m−2, vinblastine 6 mg m−2 and cisplatin 50 mg m−2 (MVP)] followed by surgery (n = 11), or to surgery alone. Of 40 eligible patients, 22 agreed to participate (feasibility 55%) and all complied with the full treatment schedule. All symptomatic patients achieved either complete (50%) or partial (50%) relief of tumour-related symptoms with pre-operative chemotherapy. Fifty-five per cent achieved objective tumour response, and a further 27% minor tumour shrinkage; none had progressive disease. Partial pathological response was seen in 50%. No severe (WHO grade III–IV) toxicities occurred. No significant deterioration in quality of life was detected during chemotherapy. Pre-operative MVP chemotherapy is feasible in early stage NSCLC, and this study has now been initiated as a UK-wide Medical Research Council phase III trial. © 1999 Cancer Research Campaign PMID:10188899

    A six-month, multicenter, randomized, open-label study was undertaken to determine whether renal function is improved using reduced-exposure cyclosporine (CsA) versus standard-exposure CsA in 199 de novo heart transplant patients receiving everolimus and steroids ± induction therapy. Mean C2 levels were at the low end of the target range in standard-exposure patients (n = 100) and exceeded target range in reduced-exposure patients (n = 99) throughout the study. Mean serum creatinine at Month 6 (the primary endpoint) was 141.0 ± 53.1 μmol/L in standard-exposure patients versus 130.1 ± 53.7 μmol/L in reduced-exposure patients (P = 0.093). The incidence of biopsy-proven acute rejection ≥3A at Month 6 was 21.0% (21/100) in the standard-exposure group and 16.2% (16/99) in the reduced-exposure group (n.s.). Adverse events and infections were similar between treatment groups. Thus, everolimus with reduced-exposure CsA resulted in comparable efficacy compared to standard-exposure CsA. No renal function benefits were demonstrated; that is possibly related to poor adherence to reduced CsA exposure. PMID:22295178

    Objectives: This phase IIIB study compared the efficacy and safety of febuxostat and allopurinol in gout patients with or without tophi who were HLA-B*5801 negative. Method: Eligible patients were randomized to a febuxostat group (80 mg QD) or an allopurinol group (300 mg QD). Following an initial 2-week washout period, over the next 12 weeks we made five measurements of serum urate levels along with assessments of adverse events (AEs). Results: Forty-three out of 152 screened subjects (28.3%) were ineligible either because of the presence of the HLA-B*5801 allele or for various other reasons. The febuxostat group (n = 54) and the allopurinol group (n = 55) had no significant differences in demographic or baseline characteristics. From week 2 to week 12, the febuxostat group had a significantly lower serum urate level than the allopurinol group (p ≤ 0.001 for all comparisons) and significantly more patients with serum urate levels less than 6.0 mg/dL. The serum urate levels of the febuxostat group declined by more than 40% from week 2 to week 12 and this decrease was greater than that in the allopurinol group (~30%). The two groups were similar in terms of AEs. Conclusions: Febuxostat was more effective than allopurinol in reducing the serum urate levels of Han Chinese patients with gout or tophaceous gout who were HLA-B*5801 negative, without causing any serious skin reactions. Febuxostat should be considered for treatment of Han Chinese patients with gout who are HLA-B*5801 negative. PMID:26771445

    We studied hematological indexes (RBC, HB, HT, MCV), serum iron and serum ferritin values in 1784 randomly selected subjects aged 65 and over (725 males and 1059 females) divided into five age groups (65-69, 70-74, 75-79, 80-84, > or = 85 years). The subjects were classified as anemic and normochromic according to the criteria for a "geriatric" level of anemia (HB < or = 12 g/dL in both sexes) as well as "W.H.O." levels for anemia (HB < 13 g/dL in males and < 12 g/dL in females). Macrocytosis (MCV > 100 fl) and low serum ferritin level (< or = 12 ng/dL) were classified according to MCV and serum ferritin values. Mean HB values in males were 14.85 +/- 1.33; 14.82 +/- 1.40; 14.77 +/- 1.43; 14.59 +/- 1.47 and 13.83 +/- 1.13 in the five age groups (65-69, 70-74, 75-79, 80-84 and > or = 85 years) respectively; in females, they were 13.77 +/- 1.15; 13.75 +/- 1.27; 13.44 +/- 1.39; 13.44 +/- 1.52 and 13.34 +/- 1.61, respectively. There was a low frequency of anemia in the entire sample: 2.9% in males and 9.9% in females according to the "geriatric" level, and 9.4% in males and 8.8% in females according to the "W.H.O." level. There was a higher prevalence of macrocytosis in males (6.3%) than in females (3.3%). We conclude that red cell parameters tend to decrease in aging, and further investigations are needed that exclude persons with existing chronic conditions, and incorporate data on nutritional status.

    Objectives: The biceps tendon is recognized as a significant source of pain in the shoulder for many patients. Operative techniques for tenodesis of the biceps tendon vary widely. No studies have been conducted directly comparing arthroscopic proximal vs. open subpectoral biceps tenodesis using a prospective study. We aim to compare the functional outcomes, pain relief, and complications of proximal vs. subpectoral biceps tenodesis. Methods: A prospective randomized study of 129 consecutive patients requiring biceps tenodesis for treatment of biceps tendon tears, biceps instability or superior labral tears was performed. Clinical outcome measures used to conduct the study included active range of motion, VAS pain score, ASES score and SANE scores. Complications and revisions were also documented. Results: Mean follow-up was 13.2 months (12-24 months) with 50 subpectoral tenodesis and 46 proximal tenodesis patients reaching minimum follow-up of 12 months. In the subpectoral group, the VAS improved from 5.7 to 2.0 (p < 0.001), ASES score improved from 49.8 to 77.7 (p< 0.001), and SANE scores improved from 42.1% to 77.7% (p<0.001). In the arthroscopic proximal tenodesis group, the VAS pain score improved from 5.9 to 1.8 (p<0.001), ASES score improved from 52.0 to 82.5 (p<0.001), and SANE scores improved from 42.8% to 78.6% (p<0.001). The revision rate for the subpectoral group was 4% (2/50 patients). The revision rate for the arthroscopic proximal tenodesis group was 8.6% (4/46). Twelve patients had persistent tenderness over the bicipital groove: 7 following proximal tenodesis and 5 following subpectoral tenodesis. No significant difference was found between methods in any outcome measures evaluated. Conclusion: This study found no difference in the functional outcomes or pain relief between proximal vs subpectoral biceps tenodesis. However, revision rates and occurrence of post-operative persistent bicipital groove pain for arthroscopic proximal tenodesis with

    INTRODUCTION: The routine use of a nasogastric tube after elective colorectal surgery is no longer mandatory. More recently, early feeding after laparoscopic colectomy has been shown to be safe and well tolerated. Therefore, the aim of our study was to prospectively assess the safety and tolerability of early oral feeding after elective "open" abdominal colorectal operations. MATERIALS AND METHODS: All patients who underwent elective laparotomy with either colon or small bowel resection between November 1992 and April 1994 were prospectively randomized to one of the following two groups: group 1: early oral feeding--all patients received a clear liquid diet on the first postoperative day followed by a regular diet as tolerated; group 2: regular feeding--all patients were treated in the "traditional" way, with feeding only after the resolution of their postoperative ileus. The nasogastric tube was removed from all patients in both groups immediately after surgery. The patients were monitored for vomiting, bowel movements, nasogastric tube reinsertion, time of regular diet consumption, complications, and length of hospitalization. The nasogastric tube was reinserted if two or more episodes of vomiting of more than 100 mL occurred in the absence of bowel movement. Ileus was considered resolved after a bowel movement in the absence of abdominal distention or vomiting. RESULTS: One hundred sixty-one consecutive patients were studied, 80 patients in group 1 (34 males and 46 females, mean age 51 years [range 16-82 years]), and 81 patients in group 2 (43 males and 38 females, mean age 56 years [range 20-90 years]). Sixty-three patients (79%) in the early feeding group tolerated the early feeding schedule and were advanced to regular diet within the next 24 to 48 hours. There were no significant differences between the early and regular feeding groups in the rate of vomiting (21% vs. 14%), nasogastric tube reinsertion (11% vs. 10%), length of ileus (3.8 +/- 0.1 days vs. 4

  14. The INCH-Trial: a multicentre randomized controlled trial comparing the efficacy of conventional open surgery and laparoscopic surgery for incisional hernia repair

    2013-01-01

    Background Annually approximately 100.000 patients undergo a laparotomy in the Netherlands. About 15,000 of these patients will develop an incisional hernia. Both open and laparoscopic surgical repair have been proven to be safe. However, the most effective treatment of incisional hernias remains unclear. This study, the ‘INCH-trial’, comparing cost-effectiveness of open and laparoscopic incisional hernia repair, is therefore needed. Methods/Design A randomized multi-center clinical trial comparing cost-effectiveness of open and laparoscopic repair of incisional hernias. Patients with a symptomatic incisional hernia, eligible for laparoscopic and open incisional hernia repair. Only surgeons, experienced in both open and laparoscopic incisional hernia repair, will participate in the INCH trial. During incisional hernia repair, a mesh is placed under or on top of the fascia, with a minimal overlap of 5 cm. Primary endpoint is length of hospital stay after an incisional hernia repair. Secondary endpoints are time to full recovery within three months after index surgery, post-operative complications, recurrences, mortality and quality of life. Our hypothesis is that laparoscopic incisional hernia repair comes with a significant shorter hospital stay compared to open incisional hernia repair. A difference of two days is considered significant. One-hunderd-and-thirty-five patients are enrolled in each treatment arm. The economic evaluation will be performed from a societal perspective. Primary outcomes are costs per patient related to time-to-recovery and quality of life. The main goal of the trial is to establish whether laparoscopic incisional hernia repair is superior to conventional open incisional hernia repair in terms of cost-effectiveness. This is measured through length of hospital stay and quality of life. Secondary endpoints are re-operation rate due to post-operative complications or recurrences, mortality and quality of life. Discussion The difference

  15. I-ONE therapy in patients undergoing total knee arthroplasty: a prospective, randomized and controlled study

    PubMed Central

    2012-01-01

    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 < 0.05 was considered statistically significant. 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

    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 short-term increases

    Background Multiple studies have been conducted that demonstrate the superiority of patch angioplasty over primary closure for carotid endarterectomy (CEA). Patch angioplasty with poly-tetrafluorethylene patches (ACUSEAL) have shown results comparable to patch angioplasty with saphenous vein and polyester patches. This is a prospective randomized study to compare the clinical outcomes of CEA using ACUSEAL versus bovine pericardium patching (Vascu-Guard). Methods Two hundred patients were randomized (1:1) to either ACUSEAL or Vascu-Guard patching. Demographic data/clinical characteristics were collected. Intraoperative hemostasis times and the frequency of reexploration for neck hematoma were recorded. All patients received immediate and 1-month postoperative duplex ultrasound studies, which were repeated at 6-month intervals. A Kaplan–Meier analysis was used to estimate the risk of restenosis and the stroke-free survival rates. Results The demographics were similar in both groups, except for a higher incidence of current smokers in the ACUSEAL group and more patients with congestive heart failure in the Vascu-Guard group (P = 0.02 and 0.03, respectively). The mean operative internal carotid artery diameter and the mean arteriotomy length were similar in both groups. The mean hemostasis time was 4.90 min for ACUSEAL patching vs. 3.09 min for Vascu-Guard (P = 0.027); however, the mean operative times were similar for both groups (ACUSEAL 2.09 hr vs. Vascu-Guard 2.16 hr, P = 0.669). The incidence of reexploration for neck hematoma was higher in the Vascu-Guard group; 6.12% vs. 1.03% (P = 0.1183). The incidence of perioperative ipsilateral neurologic events was 3.09% for ACUSEAL patching vs. 1.02% for Vascu-Guard patching (P = 0.368). The mean follow-up period was 15 months. The respective freedom from ≥70% carotid restenosis at 1, 2, and 3 years were 100%, 100%, and 100% for ACUSEAL patching vs. 100%, 98%, and 98% for Vascu-Guard patching (P = 0.2478). The

    Alveolar air leaks, often resulting from lung tissue traumatization during dissection of fissures, still remain a challenging problem in lung surgery. Several tools and techniques have been used to reduce air leakage, but none was judged ideal. This prospective, randomized trial was designed to evaluate the feasibility, safety, and effectiveness of completion of fissures during pulmonary lobectomy by using a laser system. A standard stapler technique was used for comparison; the primary goal was to reach at least a comparable result. Forty-four patients were enrolled, 22 were treated with standard technique by using staplers (S) and 22 underwent laser (L) dissection. Randomization to one of the two groups was intraoperative after evaluating the presence of incomplete fissure (grade 3-4 following Craig's classification). A Thulium laser 2010 nm (Cyber TM, Quanta System, Italy) was used at power of 40 W. Outcome primary measures were the evaluation and duration of intra- and postoperative air leaks, the rate of complications, and the hospital stay. Air leaks (2.1 ± 4.2 vs 3.6 ± 7.2 days; p = 0.98) and chest tube duration (6.4 ± 4.2 vs 7.5 ± 6.3 days, p = 0.44) were lower in L compared with S group even if these were not statistically significant. Complications (36.4 vs 77.3 %; p = 0.006), hospital stay (6.9 ± 3.8 vs 9.9 ± 6.9 days; p = 0.03), hospitalization costs (5,650 vs 8,147 euros; p = 0.01), and procedure costs (77 % of difference; p < 0.0001) were significantly lower for L group, while operative time was longer (197 ± 34 vs 158 ± 41 min; p = 0.004). The use of laser dissection to prevent postoperative air leaks is effective and comparable with stapler technique. Aero-haemostatic laser properties (by sealing of small blood vessels and checking air leaks) allow a safe application during pulmonary lobectomy in interlobar fissure completion avoiding stapler use.

    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

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 short-term increases or

    Background This randomized prospective clinical trial compared the hepatic venous outflow drainage and renal function after conventional with venovenous bypass (n = 15) or piggyback (n = 17) liver transplantation. Methods Free hepatic vein pressure (FHVP) and central venous pressure (CVP) measurements were performed after graft reperfusion. Postoperative serum creatinine (Cr) was measured daily on the first week and on the 14th, 21st and 28th postoperative days (PO). The prevalence of acute renal failure (ARF) up to the 28th PO was analyzed by RIFLE-AKIN criteria. A Generalized Estimating Equation (GEE) approach was used for comparison of longitudinal measurements of renal function. Results FHVP-CVP gradient > 3 mm Hg was observed in 26.7% (4/15) of the patients in the conventional group and in 17.6% (3/17) in the piggyback group (p = 0.68). Median FHVP-CVP gradient was 2 mm Hg (0–8 mmHg) vs. 3 mm Hg (0–7 mm Hg) in conventional and piggyback groups, respectively (p = 0.73). There is no statistically significant difference between the conventional (1/15) and the piggyback (2/17) groups regarding massive ascites development (p = 1.00). GEE estimated marginal mean for Cr was significantly higher in conventional than in piggyback group (2.14 ± 0.26 vs. 1.47 ± 0.15 mg/dL; p = 0.02). The conventional method presented a higher prevalence of severe ARF during the first 28 PO days (OR = 3.207; 95% CI, 1.010 to 10.179; p = 0.048). Conclusion Patients submitted to liver transplantation using conventional or piggyback methods present similar results regarding venous outflow drainage of the graft. Conventional with venovenous bypass technique significantly increases the harm of postoperative renal dysfunction.

    Introduction We conducted a prospective randomized trial to evaluate the merits of two established postoperative pain management strategies: thoracic epidural (EPI) versus patient-controlled analgesia (PCA) with intravenous narcotics after minimally invasive repair of pectus excavatum. Pain scores favored the EPI group for the first two postoperative days only. Critics of the trial suggest that if the epidural failure rate was not so high, results may have favored the EPI group. Therefore, we performed a subset analysis of the EPI group to evaluate the impact of these failures. Methods Patients for whom epidural catheter could not be placed or whose catheters were removed early owing to dysfunction were compared with those with well-functioning catheters. Those with well-functioning catheters were also compared with the PCA group. A two-tailed independent Student t-test and a two-tailed Fisher exact test were used where appropriate. Results Of 55 patients in the EPI group, 12 patients (21.8%) had failed placement or required early removal. Comparing those with failed placements with the rest of the group, there was no difference in daily visual analogue scale pain scores or measures of hospital course. Likewise, comparing those with well-functioning catheters only to those in the PCA group, the results of the trial are replicated in terms of pain scores, hospital course, and length of stay. Conclusion In patients with failed epidural therapy, there is no significant difference in postoperative hospital course. Comparing those with well-functioning catheters to those in the PCA group, trial results are replicated-that is, no significant difference in length of stay, time to regular diet, or time to transition to oral medications. Therefore, failure rate in the EPI group did not influence the results of the trial. PMID:25643246

    Background Isolation of the pulmonary veins (PVs) for the treatment of atrial fibrillation (AF) is often supplemented with linear lesions within the left atrium (LA). However, there are conflicting data on the effects of creating a roof line (RL) joining the superior PVs in paroxysmal atrial fibrillation (PAF). Methods and Results A cohort of 120 patients with drug‐refractory PAF referred for ablation were prospectively randomized into 2 strategies: (1) PV isolation in combination with RL ablation (LA roof ablation [LARA]‐1: 59 patients) or (2) PV isolation (LARA‐2: 61 patients). Follow‐up was performed at 1, 3, and 6 months after the procedure and every 6 months thereafter. After a 3‐month blanking period, recurrence was defined as the ocurrence of any atrial tachyarrhythmia lasting ≥30 seconds. PV isolation was achieved in 89% and complete RL block in 81%. RF duration, fluoroscopy, and procedural times were slightly, but not significantly, longer in the LARA‐1 group. After 15±10 months, there was no difference in the arrhythmia‐free survival after a single AF ablation procedure (LARA‐1: 59% vs. LARA‐2: 56% at 12 months; log rank P=0.77). The achievement of complete RL block did not influence the results. The incidence of LA macroreentrant tachycardias was 5.1% in the LARA‐1 group (n=3) versus 8.2% in the LARA‐2 (n=5) (P=ns). Univariate analysis only identified AF duration as a covariate associated with arrhythmia recurrence (hazard ratio, 1.01 [95% confidence interval, 1.002 to 1.012]; P<0.01). Conclusion The linear block at the LA roof is not associated with an improved clinical outcome compared with PV isolation alone. Clinical Trial Registration URL: ClinicalTrials.gov.

    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. PMID:9460945

    This prospective study of comparing transperineal prostate biopsy (TPBx) with transrectal prostate biopsy (TRBx) was aimed to provide evidence for clinicians to select the appropriate biopsy approach under different conditions. TPBx (n = 173) and TRBx (n = 166) were performed randomly for 339 patients who were suspicious of prostate cancer (PCa). The cancer detection rate (CDR), complication rate, visual analogue scale (VAS) score, most painful procedure, number of repeated biopsy and additional anesthesia, and operating time (starting from lying down on the operating table to getting up) were recorded. The results showed that TPBx and TRBx were equivalent in CDR (35.3% vs. 31.9%) and minor complication rate (44.9% vs. 41.0%) (both P > 0.05). The major complication rate was lower in TPBx than in TRBx (0.6% vs. 4.3%, P < 0.05). TPBx was more time-consuming (17.51 ± 3.33 min vs. 14.73 ± 3.25 min) and painful (VAS score: 4.0 vs. 2.0); and it had higher rates of repeated biopsy (3.2% vs. 1.1%) and additional anesthesia (15.0% vs. 1.2%) (all P < 0.05). In summary, both TPBx and TRBx are effective to detect PCa. The major complication rate for TRBx is higher, whereas TPBx procedure is more complex and painful. PMID:26526558

    Benefits of immediate postinjury nutritional support remain ill defined. Seventy-five consecutive patients undergoing emergent celiotomy with an abdominal trauma index (A.T.I.) greater than 15 were randomized prospectively to a control group (no supplemental nutrition during first 5 days) or enteral-fed group. The enteral patients had a needle catheter jejunostomy (N.C.J.) placed at laparotomy with the constant infusion of an elemental diet (Vivonex HN) begun at 18 hours and advanced to 3,000 ml/day (3,000 kcal, 20 gm N2) within 72 hours. Control and enteral-fed groups were comparable with respect to demographic features, trauma mechanism, shock, colon injury, splenectomy, A.T.I., and initial nutritional assessment. Twenty (63%) of the enteral patients were maintained on the elemental diet greater than 5 days; four (12%) needed total parenteral nutrition (T.P.N.). Nine (29%) of the control patients required T.P.N. Nitrogen balance was markedly improved (p less than 0.001) in the enteral-fed group. Although visceral protein markers and overall complication rate were not significantly different, septic morbidity was greater (p less than 0.025) in the control group (abdominal infection in seven and pneumonia in two) compared to the enteral-fed patients (abdominal abscess in three). Analysis of patients with A.T.I. 15-40 disclosed sepsis in seven (26%) of the control versus one (4%) of the enteral-fed group (p less than 0.01). Our clinical experience demonstrates the feasibility of immediate postoperative enteral feeding via N.C.J. after major abdominal trauma, and suggests this early nutrition reduces septic complications in critically injured patients.

    The best surgical technique for pilonidal sinus disease (PSD) is still disputed. The objective of this prospective randomized study is to compare the short and long-term results of modified Limberg flap and Karydakis flap surgeries that have been widely used in recent years. Ninety one patients were included in the study. The patients were divided into two groups: modified Limberg flap (MLF; n = 46) and Karydakis flap (KF; n = 45). Preoperative findings of the patients, their surgical findings, and short and long-term postoperative findings were recorded and statistically compared. While no significant difference was discovered between the groups in terms of postoperative analgesic need, hospital stay, postoperative infection rate, drain stay time, painless sitting time, painless toilet-sitting time, and painless walking time, return to work or school time was shorter in the MLF group compared with the KF group (20.61 ± 7.89 days, 23.29 ± 6.42, respectively; P < 0.05). Cosmetically, the visual analog scale (VAS) of the KF group was significantly higher than that of the MLF group (VAS score 7.12 ± 1.28, 5.45 ± 1.77, respectively; P < 0.05). Considering recurrence rates, no statistically significant difference was found between the groups. Our study found out that short and long-term results of the MLF and KF procedures are similar. We believe both methods can be safely used in surgical PSD treatment given that in the MLF procedure, shorter return-to-work time is achieved, while the procedure provides better cosmetic results.

    To investigate clinical, biomechanic and histomorphometric effects of zoledronic acid on osteoporotic rats’ tibiae after bilateral ooforectomy. Methods: 40 female Wistar (Rattus novergicus albinus) rats were prospectively studied. On the 60th day of life, the animals were randomized into two groups according to the surgical procedure: bilateral ooforectomy (O) (n=20) and sham surgery (“sham”) (P) (n=20). After 30 days, the animals were divided into four groups, according to the administration of zoledronic acid (ZA) 0.1mg/kg or distilled water (DW): OZA (n=10), ODW (n=10), PZA (n=10) and PDW (n=10). After 12 months, the animals were sacrificed, and had their tibiae assessed. In the clinical study, animals’ weight was considered; in the biomechanical study, compressive assays were applied and, in the histomorphometric analysis, the bone trabecular area was determined. Results: “O” groups showed a significantly greater weight gain than “P” groups (p=0.005). Groups OZA and PZA showed an insignificant weight gain when compared to ODW (p=0.47) and PDW (p=0.68). The groups receiving zoledronic acid and distilled water were able to bear maximum load, similar (p=0.2), at the moment of fracture. In the groups receiving zoledronic acid, an insignificant increase of the bone trabecular area was found when compared to the groups receiving distilled water (p=0.21). There was a positive correlation between trabecular area and maximum load (p=0.04; r=0.95). Conclusion: Zoledronic acid did not significantly influence animals’ weight. The results showed an insignificant increase both of the tibial shaft bone resistance and the bone trabecular area. PMID:26998455

    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. PMID:27279390

    The GOLFIG-2 phase III trial was designed to compare the immunobiological activity and antitumor efficacy of GOLFIG chemoimmunotherapy regimen with standard FOLFOX-4 chemotherapy in frontline treatment of metastatic colorectal cancer (mCRC) patients. This trial was conceived on the basis of previous evidence of antitumor and immunomodulating activity of the GOLFIG regimen in mCRC. GOLFIG-2 is a multicentric open/label phase III trial (EUDRACT: 2005-003458-81). Chemo-naive mCRC patients were randomized in a 1:1 ratio to receive biweekly standard FOLFOX-4 or GOLFIG [gemcitabine (1000 mg/m(2), day 1); oxaliplatin (85 mg/m(2), day 2); levofolinate (100 mg/m(2), days 1-2), 5-fluorouracil (5-FU) (400 mg/m(2) in bolus followed by 24 h infusion at 800 mg/m(2),days 1-2), sc. GM-CSF (100 μg, days 3-7); sc. aldesleukin (0·5 MIU bi-daily, days 8-14 and 17-30)] treatments. The study underwent early termination because of poor recruitment in the control arm. After a median follow-up of 43.83 months, GOLFIG regimen showed superiority over FOLFOX in terms of progression-free survival [median 9·23 (95% confidence interval (CI), 6·9-11.5) vs. median 5.70 (95% CI, 3.38-8.02) months; hazard ratio (HR): 0.52 (95% CI, 0.35-0.77), P=0·002] and response rate [66.1% (95% CI, 0.41-0.73) vs. 37·0% (95% CI, 0.28-0.59), P=0.002], with a trend to longer survival [median 21.63 (95% CI, 18.09-25.18) vs. 14.57 mo (95% CI, 9.07-20.07); HR: 0·79 (95% CI, 0.52-1.21); P=0.28]. Patients in the experimental arm showed higher incidence of non-neutropenic fever (18.5%), autoimmunity signs (18.5%), an increase in the number of monocytes, eosinophils, CD4(+) T lymphocytes, natural killer cells, and a decrease in immunoregulatory (CD3(+)CD4(+)CD25(+)FoxP3(+)) T cells. Taken together, these findings provide proof-of-principle that GOLFIG chemoimmunotherapy may represent a novel reliable option for first-line treatment of mCRC. PMID:24316553

    OBJECTIVE: The study was conducted to determine whether the performance of an extended lymphadenectomy and retroperitoneal soft-tissue clearance in association with a pancreatoduodenal resection improves the long-term survival of patients with a potentially curable adenocarcinoma of the head of the pancreas. SUMMARY BACKGROUND DATA: The usefulness of performing an extended lymphadenectomy and retroperitoneal soft-tissue clearance in conjunction with a pancreatoduodenal resection in the treatment of ductal adenocarcinoma of the head of the pancreas is still unknown. Published studies suggest a benefit for the procedure in terms of better long-term survival rates; however, these studies were retrospective or did not prospectively evaluate large series of patients. MATERIALS AND METHODS: Eighty-one patients undergoing a pancreatoduodenal resection for a potentially curable ductal adenocarcinoma of the head of the pancreas were randomized to a standard (n = 40) or extended (n = 41) lymphadenectomy and retroperitoneal soft-tissue clearance in a prospective, multicentric study. The standard lymphadenectomy included removal of the anterior and posterior pancreatoduodenal, pyloric, and biliary duct, superior and inferior pancreatic head, and body lymph node stations. In addition to the above, the extended lymphadenectomy included removal of lymph nodes from the hepatic hilum and along the aorta from the diaphragmatic hiatus to the inferior mesenteric artery and laterally to both renal hila, with circumferential clearance of the origin of the celiac trunk and superior mesenteric artery. Patients did not receive any postoperative adjuvant therapy. RESULTS: Demographic (age, gender) and histopathologic (tumor size, stage, differentiation, oncologic clearance) characteristics were similar in the two patient groups. Performance of the extended lymphadenectomy added time to the procedure, although the difference did not reach statistical significance (397 +/- 50 minutes vs. 372

    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).

    OBJECT The object of this study was to compare the clinical, functional, and aesthetic results of 2 surgical techniques, pterional (PT) and minipterional (MPT) craniotomies, for microsurgical clipping of anterior circulation aneurysms. METHODS Fifty-eight patients with ruptured and unruptured anterior circulation aneurysms were enrolled into a prospective randomized study. The first group included 28 patients who underwent the MPT technique, and the second group comprised 30 patients who underwent the classic PT craniotomy. To evaluate the aesthetic effects, patients were asked to grade on a rule from 0 to 100 the best and the worst aesthetic result. Photographs were also taken, assessed by 2 independent observers, and classified as showing excellent, good, regular, or poor aesthetic results. Furthermore, quantitative radiological assessment (percentage reduction in thickness and volumetric analysis) of the temporal muscle, subcutaneous tissue, and skin was performed. Functional outcomes were compared using the modified Rankin Scale (mRS). Frontal facial palsy, postoperative hemorrhage, cerebrospinal fistula, hydrocephalus, and mortality were also analyzed. RESULTS Demographic and preoperative characteristics were similar in both groups. Satisfaction in terms of aesthetic result was observed in 19 patients (79%) in the MPT group and 13 (52%) in the PT group (p = 0.07). The mean score on the aesthetic rule was 27 in the MPT group and 45.8 in the PT group (p = 0.03). Two independent observers analyzed the patient photos, and the kappa coefficient for the aesthetic results was 0.73. According to these observers, excellent and good results were seen in 21 patients (87%) in the MPT and 12 (48%) in the PT groups. The degree of temporal muscle, subcutaneous tissue, and skin atrophy was 14.9% in the MPT group and 24.3% in the PT group (p = 0.01). Measurements of the temporal muscle revealed 12.7% atrophy in the MPT group and 22% atrophy in the PT group (p = 0.005). The

    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.

    Studies suggest that total hip arthroplasty (THA) performed through direct anterior (DA) approach has better functional outcomes than other surgical approaches. The immediate to very early outcomes of DA THA are not known. A prospective, randomized study examined the very early outcome of THA performed through DA versus direct lateral approach. The functional outcomes on day 1, day 2, week 6, week 12, 6 months, and 1 year were measured. Patients receiving DA THA had significantly higher functional scores during the early period following surgery. The difference in functional scores leveled out at 6 months. PMID:27241374

    In this prospective randomized clinical trial, two long-term contraceptive implants were studied with respect to hemostasis and liver function in 86 healthy young women. The two implants used were Implanon, containing the progestagen etonogestrel (the biologically active metabolite of desogestrel) and Norplant, the implant containing the progestagen levonorgestrel. The results of the trial showed that both implants had similar small effects on the hemostatic system that are not suggestive of a tendency towards thrombosis. The effect on liver function was characterized by increases in total bilirubin and gamma-glutamyl transferase and decreases in alanine aminotransferase and aspartate aminotransferase. PMID:9773263

    This prospective randomized study aims to compare the outcome between an alumina ceramic-on-ceramic (CC) articulation with a ceramic on ultra-high-molecular-weight polyethylene articulation (CP). Fifty-six hips in 55 patients with mean age 42.2 (range, 19-56) each received uncemented components, a 28-mm alumina head with randomization of acetabular liner. Mean St Michael's outcome score for each group with up to 10 years follow-up (median, 8 years; range, 1-10) was 22.8 and 22.9, respectively (P = .819). Wear was identified in all but 1 CP replacement, but only 12 of the 23 CC. Mean wear in the CP group was 0.11 mm/y and 0.02 mm/yr in the CC group (P < .001). Other than significantly greater wear in the polyethylene group, there was no significant difference in midterm outcome between the 2 groups. PMID:19195824

    The Prospective and Retrospective Memory Questionnaire (PRMQ) has been shown to have acceptable reliability and factorial, predictive, and concurrent validity. However, the PRMQ has never been administered to a probability sample survey representative of all ages in adulthood, nor have previous studies controlled for factors that are known to influence metamemory, such as affective status. Here, the PRMQ was applied in a survey adopting a probabilistic three-stage cluster sample representative of the population of Sao Paulo, Brazil, according to gender, age (20-80 years), and economic status (n=1042). After excluding participants who had conditions that impair memory (depression, anxiety, used psychotropics, and/or had neurological/psychiatric disorders), in the remaining 664 individuals we (a) used confirmatory factor analyses to test competing models of the latent structure of the PRMQ, and (b) studied effects of gender, age, schooling, and economic status on prospective and retrospective memory complaints. The model with the best fit confirmed the same tripartite structure (general memory factor and two orthogonal prospective and retrospective memory factors) previously reported. Women complained more of general memory slips, especially those in the first 5 years after menopause, and there were more complaints of prospective than retrospective memory, except in participants with lower family income.

    Aim Prospective randomized study on transperitoneal laparoscopic ureterolithotomy (TPLU) versus open ureterolithotomy (OU) for treatment of large impacted ureteric stones (≥ 1.5 cm) and assessment of overall results. Material & Methods In a prospective study between 2010 to 2012, 30 patients underwent TPLU and 30 OU based on 1:1 randomization. The operation was indicated primarily in 44 cases or after failed shock-wave lithotripsy/ureteroscopy in 16 cases. Two groups were compared for operative time, success rate, visual pain score, analgesic requirement, hospital stay, and postoperative complications. Statistical analysis was performed with SPSS® version 16.0 using Fisher exact or Mann-Whitney U tests with p < 0.05 considered statistically significant. Results The difference in visual pain score (6.2 in TPLU group vs 3.1 in OU group on day 1; 4.8 vs. 2.4 on day 2) and tramadol requirements (184.32 mg in TPLU group vs. 150.87 mg in OU group on day 1; 97.34 mg vs. 65.56 mg on day 2) were statistically significant and more in OU. Hospital stay and convalescence were significantly lower in the TPLU. However, stone removal in one attempt was similar in both the groups. Conclusion Although successful stone removal rates are equal in both groups, TPLU is associated significantly with less postoperative pain, less analgesic requirement, shorter hospital stay and short convalescence in comparison to OU.

    Background: The primary aim of this prospective study was to investigate the effects of laser epilation on patient satisfaction and recurrence in patients who underwent pilonidal sinus surgery. Method: Sixty patients scheduled for pilonidal sinus surgery in our clinic between 2011 and 2012 were enrolled in this prospective randomized controlled study. Patients were divided in two groups of 30 patients each. Only the Karydakis flap reconstruction technique was performed in the first group. Two sessions of laser epilation were applied in the second group in addition to Karydakis flap reconstruction. The patients in the second group underwent laser epilation 2 weeks before and 3 weeks after the surgery for a total of 2 times in a private office. Results: There were no statistically significant differences between the groups in terms of age, gender, smoking usage, ASA Score, duration of patient’s complaints, BMI and hospital stay. There were no statistically significant differences between the groups in terms of surgical site infection, wound separation, abscess formation at the any time postoperatively. There were statistically significant differences between the two groups in the first week post operation considering the VAS pain score (P<0.03) and VAS satisfaction score (P<0.01). While there were statistically significant differences between the two groups in the first month post operation considering the VAS pain score (P<0.0001), there were no statistically significant differences between the groups in terms of VAS satisfaction score in the first and three month postoperatively. In the telephone interviews done 1 year after the surgery, recurrence were detected in 4% of first group and in 20% of second group. Recurrence rates were significantly higher in the second group (P=0.045). Conclusion: Our results show that laser epilation does not reduce the relapse rates in pilonidal sinus surgery, as expected.

    The randomized prospective double-blinded clinical trial (RCT) is accepted as Level I evidence and is highly regarded. However, RCTs that gained FDA approval of drugs such as Vioxx, Fen-Phen, and oral and intravenous bisphosphonates have proven to generate misleading results and have not adequately identified serious adverse reactions. The development, research, and clinical marketing of the oral and intravenous bisphosphonates can serve as a representative example for the deteriorated value of many of today's RCTs. The expected high value of RCTs is jeopardized by: (1) sponsorship that incorporates bias; (2) randomization that can select out an expected improved result or eliminate higher-risk individuals; (3) experimental design that can avoid recognition of serious adverse reactions; (4) blinding that can easily become unblinded by the color, shape, odor, or administration requirements of a drug; (5) definitions that can define an observation as something other than what it actually represents, or fail to define it as an adverse reaction; (6) labeling of retrospective data as a prospective trial by using adjudicators prospectively to look at retrospective data; (7) change of the length of study to avoid the longer-term adverse reaction from accumulation of drug or treatment effects; (8) ghost writing, as when drug company physicians or a hired corporation either edit or write the entire protocol and/or manuscript for publication. Such corruption of the well-intended properly conducted RCT should be viewed with a sense of outrage by practitioners and requires a restructuring of the levels of evidence accepted today.

  2. Use of drug therapy in the management of symptomatic ureteric stones in hospitalized adults (SUSPEND), a multicentre, placebo-controlled, randomized trial of a calcium-channel blocker (nifedipine) and an α-blocker (tamsulosin): study protocol for a randomized controlled trial

    PubMed Central

    2014-01-01

    Background Urinary stone disease is common, with an estimated prevalence among the general population of 2% to 3%. Ureteric stones can cause severe pain and have a significant impact on quality of life, accounting for over 15,000 hospital admissions in England annually. Uncomplicated cases of smaller stones in the lower ureter are traditionally treated expectantly. Those who fail standard care or develop complications undergo active treatment, such as extracorporeal shock wave lithotripsy or ureteroscopy with stone retrieval. Such interventions are expensive, require urological expertise and carry a risk of complications. Growing understanding of ureteric function and pathophysiology has led to the hypothesis that drugs causing relaxation of ureteric smooth muscle, such as the selective α-blocker tamsulosin and the calcium-channel blocker nifedipine, can enhance the spontaneous passage of ureteric stones. The use of drugs in augmenting stone passage, reducing the morbidity and costs associated with ureteric stone disease, is promising. However, the majority of clinical trials conducted to date have been small, poor to moderate quality and lacking in comprehensive economic evaluation. This trial aims to determine the clinical and cost-effectiveness of tamsulosin and nifedipine in the management of symptomatic urinary stones. Methods/design The SUSPEND (Spontaneous Urinary Stone Passage ENabled by Drugs) trial is a multicentre, double-blind, randomized controlled trial evaluating two medical expulsive therapy strategies (nifedipine or tamsulosin) versus placebo. Patients aged 18 to 65 with a ureteric stone confirmed by non-contrast computed tomography of the kidney, ureter and bladder will be randomized to receive nifedipine, tamsulosin or placebo (400 participants per arm) for a maximum of 28 days. The primary clinical outcome is spontaneous passage of ureteric stones at 4 weeks (defined as no further intervention required to facilitate stone passage). The

    Objectives Radical cystectomy (RC) is associated with significant blood loss and transfusion requirement. We performed a prospective, randomized trial to compare blood loss, operative time, and cost using 2 different and commonly employed approaches to tissue ligation and division during RC: mechanical (stapler device) and electrosurgical (heat-sealing device). Methods and materials Eighty patients undergoing RC for urothelial bladder carcinoma were randomized to use of either an Endo GIA Stapler or Impact LigaSure device for tissue ligation and division. Primary outcomes were blood loss, operative time, and device costs. Data were analyzed with Wilcoxon rank sum test and Welch 2-sample t test. Results There were no significant demographic or preoperative differences between the cohorts. Mean estimated blood loss was similar between the electrosurgical (687 ml) and stapler (708 ml) arms (P = 0.850). There were no significant differences between cohorts when comparing operative times or transfusion requirement. There was a significant increase in the mean number of adjunctive suture ligatures used in the stapling device arm (3.0 vs. 1.5, P = 0.047). Total device costs were significantly lower with the LigaSure compared with the GIA Stapler ($625.00 vs. $1490.10, P < 0.001). There were no complications attributable to either device. Conclusions This prospective, randomized study demonstrates no significant difference in blood loss, transfusion requirement, or safety between mechanical vs. electrosurgical control of the vascular pedicles. The LigaSure device, however, is significantly less costly than the GIA Stapler and required fewer additional measures for hemostasis. PMID:24054870

    Few prospective, randomized studies have assessed benefits of laparoendoscopic single site donor nephrectomy (LESS-DN) over laparoscopic donor nephrectomy (LDN). Our center initiated such a trial in January 2011, following subjects randomized to LESS-DN vs. LDN from surgery through 5 years post-donation. Subjects complete recovery/satisfaction questionnaires at 2, 6, and 12 months post-donation; transplant recipient outcomes are also recorded. 100 subjects (49 LESS-DN, 51 LDN) underwent surgery; donor demographics were similar between groups, and included a predominance of female, living unrelated donors, mean age of 47 years who underwent left donor nephrectomy. Operative parameters (overall time, time to extraction, warm ischemia time, blood loss) were similar between groups. Conversion to hand-assist laparoscopy was required in 3 LESS-DN (6.1%) vs. 2 LDN (3.9%; P=0.67). Questionnaires revealed 97.2% of LESS-DN vs. 79.5% of LDN (P=0.03) were 100% recovered by two months after donation. No significant difference was seen in satisfaction scores between the groups. Recipient outcomes were similar between groups. Our randomized trial comparing LESS donor nephrectomy to LDN confirms that LESS-DN offers a safe alternative to conventional LDN in terms of intra- and post-operative complications. LDN and LESS-DN offer similar recovery and satisfaction after donation. PMID:24934732

    Comfort warming systems aim to produce a comfortable local environment over which the individual patient has control. We studied a patient-adjustable comfort warming system using the Bair PAWS (Patient Adjustable Warming System) (Arizant Healthcare, Inc, Eden Prairie, MN), specifically to study comfort warming rather than therapeutic warming. One-hundred thirty patients were enrolled in this prospective randomized clinical trial, with 58 patients randomized to the patient warming gown, and 72 randomized to the warm blanket group. Groups were similar for gender, age, height, weight, surgical time, body surface area, and body mass index. The patient-adjustable warming system group had perceived greater control and satisfaction at 30 minutes after treatment was initiated compared with the warmed blanket control group. However, there were no differences in satisfaction levels with thermal comfort among those patients contacted one day postoperatively. Additional research is needed to improve external validity of study findings. Further refinement of a nursing definition of thermal comfort should be explored. PMID:20359643

    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 they relate 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.

    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. PMID:11511016

    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. PMID:26100474

    Non-hemolytic transfusion reactions (NHTR) occur in up to 30% of patients receiving platelet transfusions. Premedication with acetaminophen and diphenhydramine is a common strategy to prevent NHTR, but its efficacy has not been studied. In this prospective trial, transfusions in patients receiving pre-storage leukocyte-reduced single-donor apheresis platelets (SDP) were randomized to premedication with either acetaminophen 650 mg PO and diphenhydramine 25 mg IV, or placebo. Fifty-one patients received 98 transfusions. Thirteen patients had 15 NHTR: 15.4% (8/52) in the treatment arm and 15.2% (7/46) in the placebo arm. Premedication prior to transfusion of pre-storage leukocyte reduced SDP does not significantly lower the incidence of NHTR as compared to placebo. PMID:12111764

    Is there a difference in surgery time and complication rate when Doppler ultrasound (US) is used for the preoperative mapping of perforators in comparison with computer tomography angiography (CTA)? Women who were candidates for breast reconstruction using the deep inferior epigastric perforator (DIEP) free flap were enrolled in a prospective randomized study. The operating time was 249 ± 62 min (mean ± SD) in the CTA group (n = 32) and 255 min ± 75 in the US group (n = 31)--hence a difference of 6 min on average. No flaps were lost. Sixteen complications occurred in 15 patients: seven in the CTA group and nine in the US group. Complications were remedied without delay and all patients came through with a favorable reconstruction. Preoperative mapping of perforators with US is satisfactory enough provided the microsurgery team has proper experience in breast reconstruction with the DIEP flap. PMID:25824193

    A prospective, randomized, and double-blind study was conducted with 864 patients operated on for appendicitis. In early cases, including normal and acute appendicitis, one dose of antibiotic was given. The rate of postappendectomy septic complications in patients who received cefotaxime, cefoperazone, or moxalactam was very low (about 3%), and there was no statistical difference between the drugs. For late cases, including gangrenous and perforated appendicitis, the antibiotics were continued for 5 days. Moxalactam decreased significantly the septic complications in these patients when compared with the other two drugs. It is safe, free from serious toxic side effects, and more convenient and easier to administer than combination antibiotic therapy. The main disadvantage of moxalactam is its high cost, but this has to be balanced against the savings in nursing time, the cost of monitoring renal function and serum level when aminoglycosides are used, and the reduced usage and manipulation of infusion sets.

    The risk-stratified osteoporosis strategy evaluation study (ROSE) is a randomized prospective population-based study investigating the effectiveness of a two-step screening program for osteoporosis in women. This paper reports the study design and baseline characteristics of the study population. 35,000 women aged 65-80 years were selected at random from the population in the Region of Southern Denmark and-before inclusion-randomized to either a screening group or a control group. As first step, a self-administered questionnaire regarding risk factors for osteoporosis based on FRAX(®) was issued to both groups. As second step, subjects in the screening group with a 10-year probability of major osteoporotic fractures ≥15% were offered a DXA scan. Patients diagnosed with osteoporosis from the DXA scan were advised to see their GP and discuss pharmaceutical treatment according to Danish National guidelines. The primary outcome is incident clinical fractures as evaluated through annual follow-up using the Danish National Patient Registry. The secondary outcomes are cost-effectiveness, participation rate, and patient preferences. 20,904 (60%) women participated and included in the baseline analyses (10,411 in screening and 10,949 in control group). The mean age was 71 years. As expected by randomization, the screening and control groups had similar baseline characteristics. Screening for osteoporosis is at present not evidence based according to the WHO screening criteria. The ROSE study is expected to provide knowledge of the effectiveness of a screening strategy that may be implemented in health care systems to prevent fractures. PMID:25578146

    Outpatient cardiac catheterization is frequently performed, but the optimal recovery time after sheath removal has not been defined. Left heart catheterization was performed via the femoral artery utilizing 6 French catheters on 323 outpatients. One hundred thirty-five patients were randomized to ambulate at a mean of 2.5 hr (group 1) after puncture site compression, whereas 188 patients were randomized to ambulate at a mean of 4.1 hr (group 2). Telephone follow-up occurred within 48 hr. A small hematoma (< 5 cm) occurred in 2 (1.6%) patients in group 1 and in 4 (2.4%) patients in group 2. These results indicate that it is safe to ambulate patients 2.5 hr following 6 French diagnostic heart catheterization. PMID:9286529

    To compare the retroperitoneoscopic ureterolithotomy (RPLU) versus open mini-incision ureterolithotomy (MIOU) for large and impacted proximal or mid-ureteric stones in prospective randomized manner and to assess the outcome results. In a prospective randomized study between January 2009 and December 2012, 35 RPLU and 35 MIOU were included in the study. The indications for ureterolithotomy were as primary treatment of large and impacted stones more than 1.5 cm in the proximal and mid-ureter and as salvage treatment of failed ureteroscopy (URS)/extracorporeal shock wave lithotripsy (SWL). The two groups were compared for visual pain score on the first and second postoperative day, analgesic requirement, stone removal in one attempt, operative time, blood loss, postoperative complications, hospital stays and the period of convalescence. The difference in the visual pain score and the tramadol requirement was significantly higher in MIOU group. The hospital stay (RPLU 2.86 ± 0.43, MIOU 5.71 ± 0.67, P ≤ 0.001) and period of convalescence (RPLU 12.29 ± 4.06, MIOU 24.11 ± 5.55, P ≤ 0.001) were also significantly higher in MIOU group. The complications were 11.4 % (P ≤ 0.02) in RPLU versus 17.4 % in MIOU group. However, the stone removal in one attempt was similar in both groups. In condition of failed URS/SWL, unavailability of the full endoscopic armamentarium and limitation of costs, RPLU and MIOU both are safe and effective treatment options for large impacted upper- and mid-ureteric stones and RPLU has better tolerability, lesser hospital time and equal stone clearance rate.

    Aim The aim of this study was to establish safety and efficacy of a new sirolimus-eluting stent with bioresorbable polymer, Ultimaster (BP-SES). Sirolimus-eluting stent with bioresorbable polymer was compared with everolimus-eluting, permanent polymer, Xience stent (PP-EES) in the frame of a CENTURY II clinical trial designed to make global clinical data compliant with regulatory requirements in Europe and Japan. Methods and results The CENTURY II is a prospective, multicentre, randomized (1 : 1), single blind, controlled, non-inferiority clinical trial conducted at 58 study sites in Japan, Europe, and Korea. A total of 1123 patients requiring a percutaneous coronary intervention (PCI) procedure, with implantation of drug-eluting stent (DES), were enrolled [total population (TP)]. Randomization of patients was stratified for the subset of patients matching requirements for DES in Japan (Cohort JR, n = 722). Baseline patient demographic and angiographic characteristics were similar in both study arms, with minimal differences between the TP and Cohort JR. The primary endpoint, freedom from target lesion failure (TLF) at 9 months—TLF [composite of cardiac death, target-vessel-related myocardial infarction (MI) and target lesion revascularization]—was 95.6% with BP-SES and 95.1% with PP-EES (Pnon-inferiority<0.0001). Composite of cardiac death and MI rate was 2.9 and 3.8% (P = 0.40) and target vessel revascularization was 4.5% with BP-SES and 4.2% with PP-EES (P = 0.77). The stent thrombosis rate was 0.9% in both arms. In Cohort JR, freedom from TLF was 95.9 and 94.6% (Pnon-inferiority < 0.0005) with BP-SES and PP-EES, respectively. Conclusion The new bioresorbable polymer sirolimus-eluting stent showed safety and efficacy profiles similar to durable polymer everolimus-eluting stent at 9-month follow-up.

    Background: Ultrasound-guided transversus abdominis plane (TAP) block has been used for intra- and post-operative analgesia during abdominal operations and for ureteric shock wave lithotripsy (SWL) as well. Aim: This study aimed at comparing ultrasound-guided unilateral versus bilateral TAP blocks as analgesic techniques for unilateral ureteric SWL. Settings and Design: Prospective randomized comparative study. Patients and Methods: Sixty patients scheduled for unilateral ureteric SWL were randomly allocated into two groups: Group (U) received unilateral TAP block in the form of 25 ml of bupivacaine 0.25% (i.e., 62.5 mg), and Group (B) received bilateral TAP blocks in the form of 25 ml of bupivacaine 0.25% (i.e., 62.5 mg) on each side. Statistical Analysis: This was performed using SPSS program version 19 ((IBM Corp., Armonk, NY, USA) and EP 16 program. Results: The mean values of intra- and post-procedural visual analog scale at different time intervals were around (30), which was statistically insignificant between groups (P > 0.05). There were no significant differences between groups regarding cardiopulmonary stability, postanesthesia care unit time, the total amount of rescue fentanyl and patient satisfaction scores (P > 0.05). There were no significant side effects in both groups. Conclusion: Ultrasound-guided unilateral TAP block is as safe and effective analgesic technique as bilateral TAP blocks during unilateral ureteric SWL. It can be used as the sole analgesic technique during ureteric SWL. PMID:27453645

    Azithromycin, an azalide subclass macrolide antibiotic, is an effective, well-tolerated and safe therapeutic option for treatment of papillomatosis in humans. This study reports the clinical and histopathological results from a prospective, randomized, double-blinded, placebo-controlled trial of 17 dogs of various breeds with diagnosis of oral (n = 12) and cutaneous papillomatosis (n = 5) treated with azithromycin. Papillomas appeared as whitish, verrucous, hyperkeratotic papules 1-2.7 mm in size. The cases were randomly assigned to azithromycin (n = 10) and placebo treatment groups (n = 7). Both owners and investigators were blinded to the allocation to the groups. Azithromycin (10 mg/kg) was administered per os every 24 h for 10 days. Clinical evaluations were done by the same investigator throughout the trial. Azithromycin treatment significantly decreased clinical scores (P < 0.001), whereas there was no change seen in the placebo group. In the azithromycin treatment group, skin lesions disappeared in 10-15 days. One case in the placebo had spontaneous regression of its papillomas by day 41, but lesions were still evident at day 50 in the remaining six cases. There was no recurrence of papillomatosis in the azithromycin treated dogs (follow up 8 months). No adverse effects were seen in either group. In conclusion, azithromycin appears to be a safe and effective treatment for canine papillomatosis. PMID:18494759

    Background: postoperative nausea and vomiting (PONV) frequently hampers implementation of ambulatory surgery in spite of so many antiemetic drugs and regimens. Aims: the study was carried out to compare the efficacy of Ramosetron and Ondansetron in preventing PONV after ambulatory surgery. Setting and Design: it was a prospective, double blinded, and randomized controlled study. Methods: 124 adult patients of either sex, aged 25-55, of ASA physical status I and II, scheduled for day care surgery, were randomly allocated into Group A [(n=62) receiving (IV) Ondansetron (4 mg)] and Group B [(n=62) receiving IV Ramosetron (0.3 mg)] prior to the induction of general anesthesia in a double-blind manner. Episodes of PONV were noted at 0.5, 1, 2, 4 h, 6, 12, and 18 h postoperatively. Statistical Analysis and Results: statistically significant difference between Groups A and B (P <0.05) was found showing that Ramosetron was superior to Ondansetron as antiemetic both regarding frequency and severity. Conclusion: it was evident that preoperative prophylactic administration of single dose IV Ramosetron (0.3 mg) has better efficacy than single dose IV Ondansetron (4 mg) in reducing the episodes of PONV over 18 h postoperatively in patients undergoing day-care surgery under general anesthesia.

    The duration of antimicrobial prophylaxis in gastric cancer surgery is not yet established. This prospective randomized study was performed to confirm the noninferiority of single-dose versus multiple-dose antimicrobial prophylaxis in terms of the incidence of surgical-site infection in gastric cancer surgery. Three hundred twenty-five patients undergoing elective resection for gastric cancer were randomized to receive only single-dose cefazolin (1 g) during surgery (single-dose group) or an additional 5 doses every 12 hours postoperatively (multiple-dose group). The overall incidence of surgical-site infections was 9.1% in the single-dose group and 6.2% in the multiple-dose group [difference (95% confidence interval): −2.9% (−5.9%–0.0%)]. Multivariate logistic regression analysis identified blood loss, being overweight, and advanced age as significant independent risk factors for surgical-site infection. Single-dose antimicrobial prophylaxis seemed to be acceptable, and choosing multiple-dose prophylaxis may have little impact on the prevention of surgical-site infections in elective gastric cancer surgery.

    Objective We aimed to compare the effect of general and spinal anesthesia on maternal blood loss in elective cesarean section (CS). Material and Methods This was a prospective randomized study and included 418 healthy pregnant women with a term uncomplicated singleton pregnancy between 37 and 41 weeks of gestation. The study participants were randomly divided into two groups: the general anesthesia group and spinal anesthesia group. CSs were all performed using the same surgical technique, and within the groups, the same anesthetic procedures were used (either general or spinal). The primary outcome for this study was operative blood loss. Hemoglobin and hematocrit concentrations were compared between the two groups. Results The preoperative hemoglobin and hematocrit levels were similar in the both groups (p=0.08 and p=0.239, respectively). Significantly lower operative blood loss was achieved using spinal anesthesia versus general anesthesia during elective CS. The differences between preoperative and postoperative blood values for both the study groups were statistically significant (p<0.001). Conclusion This study demonstrates that spinal anesthesia is associated with a lower risk of operative blood loss than general anesthesia in low risk patients undergoing elective CS. PMID:26401109

    Background 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 and methods 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. Results 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. Conclusion 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. PMID:20152024

    Background and Aims: Various drugs are used for providing favorable intubation conditions during awake fiberoptic intubation (AFOI). However, most of them cause respiratory depression and airway obstruction leading to hypoxemia. The aim of this study was to compare intubation conditions, and incidence of desaturation between dexmedetomidine and fentanyl group during AFOI. Material and Methods: This randomized double-blind prospective study was conducted on a total of 60 patients scheduled for elective laparotomies who were randomly allocated into two groups: Group A received dexmedetomidine 1 mcg/kg and Group B received fentanyl 2 mcg/kg over 10 min. Patients in both groups received glycopyrrolate 0.2 mg intravenous, nebulization with 2% lidocaine 4 ml over 20 min and 10% lidocaine spray before undergoing AFOI. Adequacy of intubation condition was evaluated by cough score and post-intubation score. Incidence of desaturation, hemodynamic changes and sedation using Ramsay sedation scale (RSS) were noted and compared between two groups. Results: Cough Score (1-4), post-intubation Score (1-3) and RSS (1-6) were significantly favorable (P < 0.0001) along with minimum hemodynamic responses to intubation (P < 0.05) and less oxygen desaturation (P < 0.0001) in Group A than Group B. Conclusion: Dexmedetomidine is more effective than fentanyl in producing better intubation conditions, sedation along with hemodynamic stability and less desaturation during AFOI. PMID:25948903

    During nasal endoscopy it is essential to have proper visualization of structures with minimal discomfort to patient and surgeon. For this it is essential that the nose is well prepared before the procedure. The main objective of the study is to compare and evaluate the efficacy of cotton pledget packing versus topical sprays in preparation of nose for nasal endoscopy. The method includes prospective randomized blinded study on 100 patients. Patients were randomly divided in two groups. In first group the nose was packed with 4% lignocaine with xylometazoline nasal drops and in the other group it was prepared with 10% lignocaine topical spray and xylometazoline nose drops. Following the procedure, patient and the surgeon were asked a pre-formed questionnaire to know their experience during endoscopy. It was observed the packing group required more preparatory time as compared to the spray group. The group which was packed had less discomfort, less pain while endoscopy. The visualization of structures was significantly better in the packed group. Eight patients in the packed group did have some mucosal bleed during the process of packing which was not seen in the spray group. Both methods of preparation have merits and demerits but in terms of discomfort, pain during procedure and visualization of structure, packing of nasal cavity with 4% lignocaine and xylometazoline drops is better than spraying of nose with 10% lignocaine and xylometazoline drops.

    Background Central venous pressure (CVP) is used as a marker of cardiac preload to control intraoperative blood loss in open hepatectomies, while its reliability in laparoscopy is less certain. The aim of this randomized prospective trial was to evaluate the outcome of laparoscopic resections performed with stroke volume variation (SVV) or CVP monitoring. Methods All candidates for laparoscopic liver resection were assigned randomly to SVV or to CVP groups. Outcome was evaluated included conversion rate, cause of conversion, intraoperative blood loss, need for transfusions, length of surgery and postoperative results. Results Ninety consecutive patients were enrolled: both SVV and CVP groups included 45 patients each and were comparable in terms of patient and disease characteristics. A reduced rate of conversion was recorded in the SVV compared to the CVP group (6.7% and 17.8% respectively, p = 0.02). Blood loss was lower in the SVV group (150 mL), compared to the CVP group (300 mL, p = 0.04). Morbidity, mortality, length of stay and functional recovery were comparable. On multivariate analysis, lesion location, extent of hepatectomy and type of cardiac preload monitoring were associated significantly to risk of conversion. Conclusion SVV monitoring in laparoscopic liver surgery improves intraoperative outcome, thus enhancing the benefits of the minimally-invasive approach and fast-track protocols. PMID:26902132

    University of Wisconsin solution has become the most commonly used vascular perfusate during multiorgan donation world-wide. In the UK however, hyperosmolar citrate remains in common use. The purpose of this prospective randomized study was to compare the effect of systemic perfusion with UW or HOC on subsequent islet yield and purification for pancreata with short cold ischemic times. Seven pancreata were randomized to each group, with the donor age, pancreas weight, and period of cold ischemia being similar in both. Perfusion with UW was shown to inhibit collagenase digestion, and a higher concentration of this enzyme was needed to achieve comparable numbers of islets with good separation of exocrine and islet tissue after a similar period of digestion. There were no differences in the number, size, purity, or viability of islets between the two groups. In conclusion, UW solution offers no benefits over HOC for pancreata with short cold ischemic times, and because of its expense and need to use greater amounts of collagenase enzyme, we continue to use HOC.

    2016-01-01

    Transforaminal Epidural steroid injections (TFESI) have been widely adopted to alleviate and control radicular pain in accord with current guidelines. However, sometimes repeated steroid injections have adverse effects, and thus, this prospective randomized trial was undertaken to compare the effectivenesses of pulsed radiofrequency (PRF) administered to a targeted dorsal root ganglion (DRG) and TFESI for the treatment of radicular pain due to disc herniation. Subjects were recruited when first proved unsuccessful (defined as a score of > 4 on a visual analogue scale (VAS; 0-10 mm) and of > 30% according to the Oswestry Disability Index (ODI) or the Neck Disability Index (NDI)). Forty-four patients that met the inclusion criteria were enrolled. The 38 subjects were randomly assigned to receive either PRF (PRF group; n = 19) or additional TFESI (TFESI group; n = 19) and were then followed for 2, 4, 8, and 12 weeks. To evaluate pain intensity were assessed by VAS. ODI and NDI were applied to evaluate functional disability. Mean VAS scores for cervical and lumbar radicular pain were significantly lower 12 weeks after treatment in both study groups. NDI and ODI scores also declined after treatment. However, no statistically significant difference was observed between the PRF and TFESI groups in terms of VAS, ODI, or NDI scores at any time during follow-up. PRF administered to a DRG might be as effective as TFESI in terms of attenuating radicular pain caused by disc herniation, and its use would avoid the adverse effects of steroid. PMID:27478346

    A prospective randomized trial was performed to detect technical and clinical differences of 7F compared to 8F guiding catheters (GC) used in elective coronary angioplasty (PTCA). One hundred and fifteen patients undergoing elective PTCA with standard balloon dilatation catheters were randomized to 7F (55 pts) or 8F (58 pts) guiding catheters. The endpoints were primarily coronary artery and peripheral vascular complications; and secondarily, technical details and quantitative and qualitative angiographic quality. There was no difference between 7F or 8F GC for development of coronary or peripheral vascular complications. With 7F GC there was less blood loss (Hct, 3.5 +/- 3.4% vs. 6.5 +/- 9.6%, P = .033), and less contrast medium (160 +/- 88 mL vs. 200 +/- 119 mL, P = .049) used. Angiographic quality was similar, although visualization of lesions in the left anterior descending coronary artery in the left anterior oblique projection was improved with the 8F GC. There is no advantage of 7F GC for the prevention of coronary or peripheral vascular complications, although there was less blood loss and contrast medium used with the 7F systems. PMID:7874712

    Because of biochemical and tissue culture evidence casting doubt on the physiologic relevance of reported synergy afforded by sequential administration of methotrexate (MTX) followed by 5-fluorouracil (5-FU), a randomized controlled clinical trial was conducted in 108 patients with advanced cancer, including 70 with squamous cell carcinoma (SCC) of the head and neck, nine with SCC of other primary sites, 24 with colorectal, and five with gastric adenocarcinomas. Patients were randomized to receive weekly therapy consisting of MTX followed one hour later by 5-FU, or 5-FU followed one hour later by MTX. There was a trend to higher tumor response rates in patients treated with MTX before 5-FU (45% v 33% overall; 65% v 39% in patients with previously untreated head and neck cancer), but these differences were not significant, either by chi-square test or by multivariate stepwise logistic regression. The trend in survival favoring the reverse sequence of 5-FU before MTX was not significant in univariate analyses. Stepwise multivariate Cox model analysis showed that Eastern Cooperative Oncology Group performance status at study entry was the major prognostic factor for survival (P less than 0.001), but among the 70 patients with head and neck cancer, the sequence of drug administration was the only other significant prognostic factor for survival, and favored the sequence of 5-FU followed by MTX (P less than 0.025).

    We want to compare the efficacy and safety of vaginal versus sublingual misoprostol for cervical ripening and induction of labor. This randomized clinical trial was performed on 140 women with medical or obstetric indications for labor induction. The patients were randomly divided into two groups: vaginal and sublingual administration of misoprostol. In first group, 25 µg misoprostol was placed in the posterior fornix of the vagina and second group received 25 µg misoprostol sublingually, every 6 hours for 24 h. Maternal and neonatal outcomes were analyzed. There was no significant difference in the demographic characteristics between two groups. The main indication for cesarean section in both groups was fetal distress, followed by absence of active labor progress. Evaluation of cesarean indication was not significantly different in two groups; including fetal distress, absence of active labor, uterine over activity and failure to progress. The maternal complication in sublingual group included residual placenta (2%), tachysystole (2%), vomiting (12%), atoni (3.3%) and abdominal pain (5.5%), although there was no significant difference between two groups. Sublingual misoprostol is as effective as vaginal misoprostol for induction of labor at term. However, sublingual misoprostol has the advantage of easy administration and may be more suitable than vaginal misoprostol. PMID:24734084

    Excellent results with small stents in coronary arteries have led endovascular therapists to their use in infrapopliteal vessels. However, to date no level I evidence exists to recommend primary stenting over infrapopliteal angioplasty alone. The aim of this randomized single-center trial was to compare their 1-year outcome. A total of 38 limbs in 35 patients with critical limb ischemia were randomized to angioplasty (22 pts) or primary stenting (16 pts). Target lesions were infrapopliteal occluded (36) or stenotic (20) lesions ranging from <2 to >15 cm in length. The mean age was 72 years. At 12 months, there was no statistical difference in survival (angioplasty, 69.3%; primary stenting, 74.7%), in limb salvage (angioplasty, 90%; primary stenting, 91.7%), or in primary and secondary patency (angioplasty, 66 and 79.5%; primary stenting, 56 and 64%) between the groups Renal insufficiency was the only significant negative predicting factor for limb salvage in both groups. In conclusion, the 1-year results for both groups were broadly similar. Stenting has its place in infrapopliteal angioplasty if the procedure is jeopardized by a dissection or recoil, but our results do not support primary stenting in all cases.

    Resorbable subcuticular staples are a new way to close surgical wounds and have not been reported in the orthopedic literature. This randomized, controlled study compared a resorbable subcuticular staple system with stainless steel wound stapling in patients undergoing unilateral primary total hip arthroplasty (THA). Institutional Review Board approval and patient consent was obtained for all patients. Sixty patients (30 each group) were randomized to receive either resorbable subcuticular staples or stainless steel staples after primary THA. Incision length, number of staples used, and any staple insertion problems were recorded. Subjective reports of pain levels or incision complaints were solicited, and wound photographs were obtained on days 1 and 14 and 6 weeks postoperatively. The presence of wound drainage, erythema, wound separation, or echymosis was recorded at each visit, as well as all postoperative complications. The average incision length in the resorbable group was 13.2 cm and required 16 staples for closure, compared to 15 cm and 20 staples for the metal staple group. No infections occurred in either group, although the incidence of erythema and wound drainage at 2 weeks was higher for patients in the stainless steel group. One patient with metal staples had a postoperative hematoma requiring secondary irrigation and debridement. Patient satisfaction was higher with the resorbable staples. A resorbable subcuticular staple system can provide comparable wound closure to stainless steel staples following THA and may do so with less local discomfort, wound drainage, or erythematous reaction.

    Background Patients with symptomatic stenosis of intradural arteries are at high risk for subsequent stroke. Since the SAMMPRIS trial, stenting is no longer recommended as primary treatment; however, the results of this trial, its inclusion criteria and its center selection received significant criticism and did not appear to reflect our experience regarding natural history nor treatment complications rate. As intracranial atherosclerosis (ICAS) is the most common cause for stroke in Asian countries, we are hereby proposing a refined prospective, randomized, multicenter study in an Asian population with strictly defined patient and participating center inclusion criteria. Methods The China Angioplasty and Stenting for Symptomatic Intracranial Severe Stenosis (CASSISS) trial is an ongoing, government-funded, prospective, multicenter, randomized trial. It recruits patients with recent TIA or stroke caused by 70%–99% stenosis of a major intracranial artery. Patients with previous stroke related to perforator ischemia will not be included. Only high-volume centers with a proven track record will enroll patients as determined by a lead-in phase. Patients will be randomized (1:1) to best medical therapy alone or medical therapy plus stenting. Primary endpoints are any stroke or death within 30 days after enrollment or after any revascularization procedure of the qualifying lesion during follow-up, or stroke in the territory of the symptomatic intracranial artery beyond 30 days. The CASSISS trial will be conducted in eight sites in China with core imaging lab review at a North American site and aims to have a sample size of 380 participants (stenting, 190; medical therapy, 190). Recruitment is expected to be finished by December 2016. Patients will be followed for at least three years. The trial is scheduled to complete in 2019. Conclusion In the proposed trial, certain shortcomings of SAMMPRIS including patient and participating center selection will be addressed. The

    Background: In China, no multicenter double-blinded prospective randomized controlled study on labor induction has been conducted till now. This study is to evaluate the efficacy and safety of intravaginal accurate 25-μg misoprostol tablets for cervical ripening and labor induction in term pregnancy in nulliparous women. Methods: This was a double-blinded, prospective randomized controlled study including nulliparous women from 6 university hospitals across China. Subjects were randomized into misoprostol or placebo group with the sample size ratio set to 7:2. Intravaginal 25-μg misoprostol or placebo was applied at an interval of 4 h (repeated up to 3 times) for labor induction. Primary outcome measures were the incidence of cumulative Bishop score increases ≥3 within 12 h or vaginal delivery within 24 h. Safety assessments included the incidences of maternal morbidity and adverse fetal/neonatal outcomes. Results: A total of 173 women for misoprostol group and 49 women for placebo were analyzed. The incidence of cumulative Bishop score increases ≥3 within 12 h or vaginal delivery within 24 h was higher in the misoprostol group than in the placebo (64.2% vs. 22.5%, relative risk [RR]: 2.9, 95% confidence interval [CI]: 1.4–6.0). The incidence of onset of labor within 24 h was significantly higher in the misoprostol group than in the placebo group (48.0% vs. 18.4%, RR: 2.6, 95% CI: 1.2–5.7); and the induction-onset of labor interval was significantly shorter in the misoprostol group (P = 0.0003). However, there were no significant differences in the median process time of vaginal labor (6.4 vs. 6.8 h; P = 0.695), incidence (39.3% vs. 49.0%, RR: 0.8, 95% CI: 0.4–1.5) and indications (P = 0.683) of cesarean section deliveries, and frequencies of maternal, fetal/neonatal adverse events between the groups. Conclusion: Intravaginal misoprostol 25 μg every 4 h is efficacious and safe in labor induction and cervical ripening. PMID:26481739

    Objectives To investigate sleep quality, anxiety/depression and quality-of-life in patients with xerostomia. Materials and methods This prospective, observational, cross-sectional study was conducted among a group of xerostomia patients (n = 30) compared with 30 matched control subjects. The following evaluation scales were used to assess the psychological profile of each patient: the Hospital Anxiety and Depression Scale, the Oral Health Impact Profile-14 (OHIP-14), the Xerostomia Inventory, the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS). Results The PSQI obtained 5.3 3 ± 1.78 for patients with xerostomia compared with 4.26 ± 1.01 for control subjects (p = 0.006); ESS obtained 5.7 ± 2.1 for test patients vs 4.4 0 ± 1 for control subjects (p = 0.010). Statistical regression analysis showed that xerostomia was significantly associated with depression (p = 0.027). Conclusions Patients with xerostomia exhibited significant decreases in sleep quality compared with control subjects. PMID:26473793

    Objective: To compare outcomes of vaginal and abdominal hysterectomy procedures in women with benign gynaecological diseases. Methods: This was a prospective study of outcomes of consecutive patients who underwent total vaginal hysterectomy (VH) or abdominal hysterectomy (AH) for benign gynaecological diseases. Patient characteristics before, during, and after the operations were reviewed. Patients were followed up for three months to evaluate postoperative complications. Results: This study included a total of 313 patients. 143 patients underwent AH and 170 patients underwent VH. Baseline characteristics were similar between the two groups. There were no intraoperative complications in either group. Operation time, intraoperative blood loss, first postoperative flatus time, time to out-of-bed activity, mean maximum postoperative body temperature, and duration of fever were all significantly shorter and less severe in the VH group compared with the AH group. In addition, vaginal length in the VH group was significantly shorter than in the AH group. Conclusions: Vaginal hysterectomy has advantages over AH in the treatment of benign gynaecological diseases, providing greater efficacy and safety with minimal invasiveness. PMID:25097536

    Three recent studies demonstrated the positive effect of extracorporeal shock wave therapy (ESWT) for treating carpal tunnel syndrome (CTS). However, none have entirely proved the effects of ESWT on CTS because all studies had a small sample size and lacked a placebo-controlled design. Moreover, radial ESWT (rESWT) has not been used to treat CTS. We conducted a prospective randomized, controlled, double-blinded study to assess the effect of rESWT for treating CTS. Thirty-four enrolled patients (40 wrists) were randomized into intervention and control groups (20 wrists in each). Participants in the intervention group underwent three sessions of rESWT with nightly splinting, whereas those in the control group underwent sham rESWT with nightly splinting. The primary outcome was visual analog scale (VAS), whereas the secondary outcomes included the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ), cross-sectional area (CSA) of the median nerve, sensory nerve conduction velocity of the median nerve, and finger pinch strength. Evaluations were performed before treatment and at 1, 4, 8, and 12 weeks after the third rESWT session. A significantly greater improvement in the VAS, BCTQ scores, and CSA of the median nerve was noted in the intervention group throughout the study as compared to the control group (except for BCTQ severity at week 12 and CSA at weeks 1 and 4) (p < 0.05). This is the first study to assess rESWT in a randomized placebo-controlled trial and demonstrate that rESWT is a safe and effective method for relieving pain and disability in patients with CTS. © 2015 Orthopaedic Research Society.

    Background & Aims Hepatorenal syndrome (HRS) type 1 is a progressive functional renal failure in subjects with advanced liver disease. The aim of this study was to evaluate the efficacy and safety of terlipressin, a systemic arterial vasoconstrictor, for cirrhosis type 1 HRS. Methods A prospective, randomized, double-blind, placebo-controlled clinical trial of terlipressin was performed. Subjects with type 1 HRS were randomized to terlipressin (1 mg intravenously every 6 hours) or placebo plus albumin in both groups. The dose was doubled on day 4 if the serum creatinine (SCr) level did not decrease by 30% of baseline. Treatment was continued to day 14 unless treatment success, death, dialysis, or transplantation occurred. Treatment success was defined by a decrease in SCr level to ≤1.5 mg/dL for at least 48 hours by day 14 without dialysis, death, or relapse of HRS type 1. Results Fifty-six subjects were randomized to each arm. Treatment success with terlipressin was double that with placebo (25% vs 12.5%, P = .093). SCr level improved from baseline to day 14 on terlipressin (−0.7 mg/dL) as compared with placebo (0 mg/dL), P < .009. Terlipressin was superior to placebo for HRS reversal (34% vs 13%, P= .008), defined by decrease in SCr level ≤1.5 mg/dL. Overall and transplantation-free survival was similar between study groups; HRS reversal significantly improved survival at day 180. One nonfatal myocardial infarction occurred with terlipressin, but the total adverse event rate was similar to placebo. Conclusions Terlipressin is an effective treatment to improve renal function in HRS type 1. PMID:18471513

    Background Recent evidence suggests that STN-DBS may have a disease-modifying effect in early PD. A randomized, prospective study is underway to determine whether STN-DBS in early PD is safe and tolerable. Objectives / Methods Fifteen of thirty early PD patients were randomized to receive STN-DBS implants in an IRB-approved protocol. Operative technique, location of DBS leads, and perioperative adverse events are reported. Active contact used for stimulation in these patients were compared with 47 advanced PD patients undergoing an identical procedure by the same surgeon. Results Fourteen of the 15 patients did not sustain any long-term (> 3 months) complications from the surgery. One subject suffered a stroke resulting in mild cognitive changes and slight right arm and face weakness. The average optimal contact used in symptomatic treatment of early PD patients was: anterior −1.1±1.7mm, lateral 10.7±1.7mm, superior −3.3±2.5mm (AC-PC coordinates). This location is statistically no different (0.77mm, p> 0.05) than the optimal contact used in treatment of 47 advanced PD patients. Conclusions The perioperative adverse events in this trial of subjects with early stage PD are comparable to that reported for STN-DBS in advanced PD. The active contact position used in early PD is not significantly different from that used in late stage disease. This is the first report of the operative experience from a randomized, surgical-versus-best-medical-therapy trial for the early treatment of Parkinson’s disease. PMID:21890575

    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

    Context: The classic posterior approach to superior hypogastric plexus block (SHPB) is sometimes hindered by the iliac crest or a prominent transverse process of L5. The computed tomography (CT) – guided anterior approach might overcome these difficulties. Aims: This prospective, comparative, randomized study was aimed to compare the CT guided anterior approach versus the classic posterior approach. Settings and Design: Controlled randomized study. Materials and Methods: A total of 30 patients with chronic pelvic cancer pain were randomized into either classic or CT groups where classic posterior approach or CT guided anterior approach were done, respectively. Visual analog score, daily analgesic morphine consumed and patient satisfaction were assessed just before the procedure, then, after 24 h, 1 week and monthly for 2 months after the procedure. Duration of the procedure was also recorded. Adverse effects associated with the procedure were closely observed and recorded. Statistical Analysis Used: Student's t-test was used for comparison between groups. Results: Visual analog scale and morphine consumption decreased significantly in both groups at the measured times after the block compared with the baseline in the same group with no significant difference between both groups. The procedure was carried out in significantly shorter duration in the CT group than that in the classic group. The mean patient satisfaction scale increased significantly in both groups at the measured times after the block compared with the baseline in the same group. The patients in the CT groups were significantly more satisfied than those in classic group from day one after the procedure until the end of the study. Conclusions: The CT guided approach for SHPB is easier, faster, safer and more effective, with less side-effects than the classic approach. PMID:25191191

    Twenty out of 40 patients with onyalai admitted to Rundu State Hospital, Kavango, SWA/Namibia, were randomized to receive a vincristine sulphate bolus of 1.5 mg/m2 or an equivalent volume of normal saline intravenously on days 8 and 15 when haemorrhage or a platelet count of less than 50 X 10(9)/l persisted for more than 1 week after admission. All patients were observed in hospital for at least 21 days. Five out of 10 patients who received vincristine achieved a platelet count in excess of 100 X 10(9)/l on day 21 and only 2 out of 10 patients who received placebo achieved a similar rise in the platelet count. Two patients, neither of whom was treated with vincristine, died of cerebral haemorrhage. PMID:3738655

    Summary Background L-carnitine was proposed as a potential treatment for patients diagnosed with an autism spectrum disorder to improve mitochondrial dysfunction, but no prior randomized controlled trials have been conducted. Material/Methods Thirty subjects diagnosed with an ASD were randomly assigned to receive a standardized regimen (50 mg L-carnitine/kg bodyweight/day) of liquid L-carnitine (n=19) or placebo (n=11) for 3-months. Measures included changes in professionally completed Childhood Autism Rating Scale (CARS), hand muscle testing, and modified clinical global impression (CGI) forms; parent completed Autism Treatment Evaluation Checklist (ATEC), treatment adherence measurement (TAM), frequency and intensity of side effect rating (FISER)/global rating of side effect burden (GRSEB)/patient report of incidence of side effects (PRISE) forms; and lab testing. Results Significant improvements were observed in CARS (−2.03, 95% CI=−3.7 to −0.31), CGI (−0.69, 95% CI=−1.1 to −0.06), and ATEC scores. Significant correlations between changes in serum free-carnitine levels and positive clinical changes were observed for hand muscle strength (R2=0.23, P=0.046), cognitive scores (R2=0.27, P=0.019), and CARS scores (R2=0.20, P=0.047). Study subjects were protocol-compliant (average adherence was >85%) and generally well-tolerated the L-carnitine therapy given. Conclusions L-carnitine therapy (50 mg/kilogram-bodyweight/day) administered for 3-months significantly improved several clinical measurements of ASD severity, but subsequent studies are recommended.

    Wound closure using topical negative pressure (TNP) has been reported to be effective, but equipment costs can be prohibitive in resource-challenged countries. Because nonhealing wounds are exceedingly common in developing countries such as India, the ability to optimize wound care with limited resources is very important. To investigate the feasibility and efficacy of providing TNP in an Indian medical referral center, a randomized controlled trial comparing a locally constructed TNP device (treatment) to wet-to-dry gauze dressings (control) was conducted. Eligible study participants (N = 48) were recruited from the inpatient wards. Wound etiologies included diabetic foot ulcers (15), pressure ulcers (11), cellulitis/fasciitis (11), and "other" (11). Following enrollment, wound size was assessed using computer-aided measurements of digital photographs and block-randomized to the study arms using a concealed allocation table. Wounds in both treatment groups were débrided before dressing application and patients were followed until wound closure or being lost to follow-up for an average of 26.3 days (+/- 18.5) in the control and 33.1 days (+/- 37.3) in the treatment group. No statistically significant differences in time to closure between the two treatment groups were observed except in a subset analysis of pressure ulcers (mean 10 +/- 7.11 days for treatment and 27 +/- 10.6 days in control group, P = 0.05). Direct costs to close a pressure ulcer also were lower in the TNP than in the control group. A review of the literature suggests the outcomes obtained using a locally constructed TNP device are similar to those obtained using commercially available devices. As a result of this study, a dedicated tissue viability team has been established to identify wounds suitable for TNP, oversee treatment, monitor the need for surgical débridement, and employ wound healing principles and technology appropriately. These results suggest that inexpensive materials can be

    This pilot trial was designed to assess the safety and efficacy of SRL in liver transplant recipients with renal dysfunction. Forty patients with renal dysfunction (24-hr CrCl 40-80 mL/min) were randomized to be withdrawn from the calcineurin inhibitor (CNI) and receive sirolimus (SRL) or to continue CNI (control arm). Improvement in 24-hour CrCl was seen in the SRL arm at 3 months (75 mL/min SRL vs. 56 mL/min control, P=0.012), whereas at 12 months there was a trend toward improvement in the SRL arm (72 mL/min SRL vs. 58 mL/min control, P=0.09). Two patients, one in each arm, developed steroid-sensitive rejection. Side effects of SRL were limited and included hyperlipidemia requiring treatment (15%), pruritus (5%), and mouth sores (25%). In this trial, SRL-based immunosuppression was a safe alternative to CNI. Although early improvements were observed, withdrawing CNI and replacing it with SRL did not result in a statistically significant improvement in renal function at 12 months of follow-up.

    Objectives: To compare the clinical anesthetic efficacy of 0.5% bupivacaine and 4% articaine (both with 1:200.000 adrenaline) for anterior maxillary infiltration in healthy volunteers. Material and methods: A triple-blind split-mouth randomized clinical trial was carried out in 20 volunteers. A supraperiosteal buccal injection of 0.9 ml of either solution at the apex of the lateral incisor was done in 2 appointments separated 2 weeks apart. The following outcome variables were measured: latency time, anesthetic efficacy (dental pulp, keratinized gingiva, alveolar mucosa and upper lip mucosa and tissue) and the duration of anesthetic effect. Hemodynamic parameters were monitored during the procedure. Results: Latency time recorded was similar for both anesthetic solutions (p>0.05). No statistically significant differences were found in terms of anesthetic efficacy for dental pulp, keratinized gingiva or alveolar mucosa. Articaine had a significant higher proportion of successful anesthesia at 10 minutes after infiltration in lip mucosa and lip skin (p=0.039). The duration of anesthesia was 336 minutes for bupivacaine and 167 minutes for articaine. (p<0.001). No significant hemodynamic alterations were noted during the procedure. Conclusions: Articaine and bupivacaine exhibited similar anesthetic efficacy for maxillary infiltrations. The duration of anesthesia was longer with the bupivacaine solution, but lip anesthesia was better with articaine. Key words:Articaine, bupivacaine, maxillary, infiltrative anesthesia, long-acting anesthetics. PMID:22143708

    One hundred fourteen men with uncomplicated urethritis were randomized to receive 1 week of therapy with either doxycycline (100 mg twice daily) or ofloxacin (300 mg twice daily). Of the 109 men completing the post-treatment visit, 56 received ofloxacin and 52 (93%) were clinically cured. Forty four (83%) of the 53 men treated with doxycycline were cured. All 30 patients with gonorrhea (including three with penicillinase-producing Neisseria gonorrhoeae [PPNG] isolates) who were treated with ofloxacin became culture-negative, as compared with 32 of 34 patients receiving doxycycline. In contrast, three of 18 patients with Chlamydia trachomatis were microbiologic failures after ofloxacin therapy, while all ten treated with doxycycline were cured. Adverse effects of both treatment regimens were generally mild, and compliance was excellent except for one patient receiving doxycycline. These results show that ofloxacin, in a dosage of 300 mg taken orally twice daily for seven days, is an effective treatment for uncomplicated urethritis in men but may not reliably cure chlamydial infections.

    Background. Our study aimed to compare HTEA and intravenous patient-controlled analgesia (PCA) in patients undergoing coronary bypass graft surgery (CABG), based on haemodynamic parameters and myocardial functions. Materials and Methods. The study included 34 patients that were scheduled for elective CABG, who were randomly divided into 2 groups. Anesthesia was induced and maintained with total intravenous anesthesia in both groups while intravenous PCA with morphine was administered in Group 1 and infusion of levobupivacaine was administered from the beginning of the anesthesia in Group 2 by thoracic epidural catheter. Blood samples were obtained presurgically, at 6 and 24 hours after surgery for troponin I, creatinine kinase-MB (CK-MB), total antioxidant capacity, and malondialdehyde. Postoperative pain was evaluated every 4 hours until 24 hours via VAS. Results. There were significant differences in troponin I or CK-MB values between the groups at postsurgery 6 h and 24 h. Heart rate and mean arterial pressure in Group 1 were significantly higher than in Group 2 at all measurements. Cardiac index in Group 2 was significantly higher than in Group 1 at all measurements. Conclusion. Patients that underwent CABG and received HTEA had better myocardial function and perioperative haemodynamic parameters than those who did not receive HTEA. PMID:25918718

    We evaluated the effects of Biafine and Lipiderm ointments in preventing radiation dermatitis. The study population included 74 patients after conservative surgery for early breast carcinoma who were referred for adjuvant external beam irradiation. Patients were randomized to receive Biafine or Lipiderm or no treatment. Both study preparations were applied twice daily, starting 10 days before onset of radiotherapy and continuing until 10 days after its completion. The skin treatment was upgraded, if clinically necessary, to steroids (grade 3), antibiotics (grade 4), or pause in therapy (grade 5). Success of treatment was evaluated according to the maximal level of skin treatment, the number of gaps in radiation therapy, the impression of the patients and the subjective skin reaction, and scores of the study nurse and radiotherapist. The three groups were comparable for all clinical features, except for a lower mean age of the Biafine group. Comparative analysis of the results showed no advantage for either preparation compared to the control arm other than maximal treatment level required for a skin reaction (mean 1.7 and 1.6 vs. 2.2), which did not reach statistical significance (p=0.145). Nevertheless, 86% of the patients in both the Biafine and Lipiderm arms expressed satisfaction with the respective ointments. In conclusion, neither Biafine nor Lipiderm seems to have a radioprotective effect. PMID:11182045
