    The aims of this prospective clinical study were (1) to evaluate the clinical performance of Signum composite inlays over a 3-year period; (2) to investigate the clinical efficacy of composite inlays in premolars versus molars; and (3) to evaluate differences between 1- or 2-surface inlays and multisurface inlays. One hundred thirteen composite inlays were placed in 30 patients by a clinician. All the inlays were made by the same laboratory technician using only one composite material (Signum, Heraeus Kulzer). All the restorations were bonded with a 3-step bonding system and a composite luting cement. The restorations were assessed after placement by a clinician who had not been involved with the placement of the restorations, in accordance with the modified US Public Health Service criteria. Three of the 113 experimental restorations had to be replaced; the total failure rate was 2.6% after 3 years. At baseline, 88.5% to 100% of the inlay restorations were rated as excellent (Alpha). Statistically significant (P < .05) differences were observed during the study for surface roughness, anatomic form at the margin, marginal integrity, and inlay integrity. The comparison of the clinical outcome of inlays in premolars versus molars and with 1 or 2 surfaces versus multisurfaces showed no significant differences, except for the parameters anatomic form at the margin and marginal integrity. Composite inlays demonstrated a very high success rate (97.4%) after 3 years. Neither the size of the restorations nor the tooth type significantly affected the clinical outcome of the restorations.

    Objective: Tooth shade differentiation concerns the identification and classification of tooth shades. The objective of this project was to implement the Clinical Tooth Shade Differentiation Course in the preclinical stage of studies and to evaluate the students' perspective over a period of 3 years. Methodology: The course is planned for a duration of 10 weeks with two 45-minute sessions per semester week. The entire attendance time was 10:15 h. 2 lectures of 90 minutes each, 2 seminars of 60 min each and 2 teaching units with the phantom head and role playing took place. In addition to the various parameters of tooth shade, changes in tooth shade and the basics of dental esthetics, clinical procedures for manual and digital tooth shade determination were explained and practiced. 96% (69 of 72) of the students participated in the first evaluation in 2012/2013 (T1), and 68% of these were women. In the following year, 2013/2014 (T2), 92% (45 of 48 students) took part; 62% of these were women and 38% men. The 2014/2015 evaluation (T3) comprised 94% (45 of 48 students). Of these, 67% were women. Results: In the evaluation, the students gave the course a positive grade. The questions in "General/Organization" were given a mean (M) of 1.5 (SD=0.7) in T1 and T2 , and 1.2 (SD=0.3) in T3. The "Overall Assessment" yielded MT1=1.6 (SD=0.6), MT2=1.5 (SD=0.5) and MT3=1.1 (SD=0.3). In T1 and T2, the item "The instructor actively involved the students in the course" was given a mean of 2.1 (SD=0.9), and in T3 a mean of 1.2 (SD=0.5). Conclusions: The course presented here conceptually shows how practical dental skills can be taught in a theoretical and clinical context. Educational objectives from the role of a dental expert were taken from the national competence-based catalog of educational objectives for dentistry and can also be supplemented. The objectives can be transferred to other dental faculties. PMID:26958650

    Proficient laboratory service is the cornerstone of modern healthcare systems and has an impact on over 70% of medical decisions on admission, discharge, and medications. In recent years, there is an increasing awareness of the importance of errors in laboratory practice and their possible negative impact on patient outcomes. We retrospectively analyzed data spanning a period of 3 years on analytical errors observed in our laboratory. The data covered errors over the whole testing cycle including pre-, intra-, and post-analytical phases and discussed strategies pertinent to our settings to minimize their occurrence. We described the occurrence of pre-analytical, analytical and post-analytical errors observed at the Komfo Anokye Teaching Hospital clinical biochemistry laboratory during a 3-year period from January, 2010 to December, 2012. Data were analyzed with Graph Pad Prism 5(GraphPad Software Inc. CA USA). A total of 589,510 tests was performed on 188,503 outpatients and hospitalized patients. The overall error rate for the 3 years was 4.7% (27,520/58,950). Pre-analytical, analytical and post-analytical errors contributed 3.7% (2210/58,950), 0.1% (108/58,950), and 0.9% (512/58,950), respectively. The number of tests reduced significantly over the 3-year period, but this did not correspond with a reduction in the overall error rate (P = 0.90) along with the years. Analytical errors are embedded within our total process setup especially pre-analytical and post-analytical phases. Strategic measures including quality assessment programs for staff involved in pre-analytical processes should be intensified.

    Objective: To compare the performance and postoperative sensitivity of a posterior resin composite with that of bonded amalgam in 40 (n = 20) large sized cavities and to evaluate whether resin composite could be an alternative for bonded amalgam. Materials and Methods: This was a randomized clinical trial. Twenty patients in need of at least two posterior restorations were recruited. Authors randomly assigned one half of the restorations to receive bonded amalgam and the other half to composite restorations. Forty bonded amalgams (n = 20) and composites (n = 20) were evaluated for their performance on modified-US Public Health Service criteria and postoperative sensitivity using visual analogue scale (VAS) for 36-months. Results: Success rate of this study was 100%. First clinical alterations were rated as Bravo after 1 year in marginal discoloration, marginal adaptation, anatomical form, and surface roughness for both amalgam and composite. At the 3rd year, overall “Bravo” rated restorations were 12 for bonded amalgam and 13 for resin composites. There were no significant differences among the VAS scores of composites and bonded amalgams for all periods (P > 0.05) except for the comparisons at the 3rd year evaluation (P < 0.05). Conclusions: Within the limitation of this study, both resin composite and bonded amalgam were clinically acceptable. Postoperative sensitivity results tend to decrease more in composite restorations rather than amalgams. Therefore, it was concluded that posterior resin composite can be used even in large sized cavities. PMID:27011734

    This article describes a 3-year retrospective analysis of student clinical rotation evaluations using the Reporter-Interpreter-Manager-Educator (RIME) scoring format. The intent of the analysis was to assess scoring trends to determine whether students with high scores on the Physician Assistant National Certifying Exam (PANCE) also achieved high RIME scores on clinical rotations. The top and bottom quartiles of PANCE scores were identified for the University of Texas (UT) Southwestern Medical Center's physician assistant (PA) classes of 2010-2012 (n = 106). RIME scores for the top and bottom quartiles of students (n = 54) also were identified. RIME scores for the same cohort of students were analyzed using the top and bottom quartiles of students' PANCE scores. The Wilcoxon matched-pairs signed rank test revealed that students with top quartile PANCE scores received a higher aggregate RIME score of 557 compared with the lower quartile of PANCE performers' score of 520 (P < .03). Results for RIME scoring trends, PANCE scores, and end-of-rotation examination scores are presented. Students from the UT Southwestern Medical Center's PA classes of 2010-2012 obtained a Manager classification most often (52%), and students with higher PANCE scores also received higher RIME scores on clinical rotations.

    In this study, the clinical performance of a silorane-based resin composite (SC) vs a nano-hybrid resin composite (NHC) was evaluated in Class II cavities. From January 2012 to February 2013, a total of 29 patients (eight men, 21 women; mean age, 24 ± 5 years) received 29 pairs of restorations using both SC (Filtek Silorane, 3M ESPE) and NHC (Filtek Z550, 3M ESPE) materials. Patients were followed until February 2015. One operator performed all restorations using the corresponding adhesive resins according to the manufacturers' instructions. Two calibrated independent examiners evaluated the restorations at one week, six months, and then annually using the modified United States Public Health Service (USPHS) criteria for anatomic form, marginal adaptation, color match, surface roughness, marginal discoloration, secondary caries, and postoperative sensitivity. Changes in the USPHS parameters were analyzed with the McNemar test (α=0.05). The mean observation period was 31.2 months. Marginal adaptation was the only parameter that showed a significant difference and was worse for SC than NHC (p=0.012). At the final recall, 17 restorations from the SC group and five from the NHC group received a score of 1 (explorer catches). These scores were significantly different between baseline and final recall for SC (p<0.001) but not for NHC (p>0.05). Both NHC and SC performed similarly in Class II restorations up to three years except for marginal adaptation, for which the latter demonstrated significant deterioration at the final recall compared with baseline.

    The introduction of polymer-infiltrated ceramic network (PICN) materials may provide more options for dentists in restoring short clinical crowns and extensively damaged posterior teeth, but clinical data for their performance are lacking. The purpose of this clinical study was to compare the 3-year performance and survival rates of PICN material with those of conservative ceramic onlay restorations for endodontically treated posterior teeth using the CEREC AC chair-side system. A total of 101 onlay restorations of endodontically treated posterior teeth using the CEREC AC chair-side system were provided in 93 participants. The 101 teeth were divided into 2 groups: Vita Enamic group and Vitablocs Mark II group. Using the modified US Public Health Service quality evaluation system, 2 calibrated evaluators examined the performance of the onlay restorations over 3 years. The Kaplan-Meier method was adopted to analyze the survival rate of restorations (α=.05). The log rank test was used to compare the survival rates of the 2 groups. The Fisher exact test was performed to detect differences in the success rates for extensively damaged teeth and short clinical crown restorations between the 2 groups. The Silness and Löe gingival index was also recorded. The restoration survival rates in the 2 groups were 97.0% (Vita Enamic) and 90.7% (Vitablocs Mark II) (P>.05). Five failures were recorded (4.95%). These failures were caused by restoration debonding (60%), ceramic fractures (20%), and tooth fractures (20%). There were no significant differences between the success rates of restoring extensively damaged teeth and short clinical crowns between the 2 groups (P>.05). The periodontal condition of 25% of participants was improved 3 years after the onlay restorations. Onlay restorations of endodontically treated posterior teeth with Vita Enamic using the CEREC AC chair-side system are clinically promising prosthodontic alternatives, with a survival rate of 97.0% after 3

    To evaluate the 3-year clinical durability of the flowable bulk-fill resin composite SDR in Class I and Class II restorations. Thirty-eight pairs of Class I and 62 pairs of Class II restorations were placed in 44 male and 42 female patients (mean age 52.4 years). Each patient received at least two extended Class I or Class II restorations that were as similar as possible. In all cavities, a one-step self-etching adhesive (XenoV+) was applied. One of the cavities of each pair was randomly assigned to receive the flowable bulk-fill resin composite SDR in increments up to 4 mm as needed to fill the cavity 2 mm short of the occlusal cavosurface. The occlusal part was completed with an ormocer-based nanohybrid resin composite (Ceram X mono+). In the other cavity, only the resin composite CeramX mono+ was placed in 2 mm increments. The restorations were evaluated using slightly modified USPHS criteria at baseline and then annually for 3 years. Caries risk and bruxing habits of the participants were estimated. No post-operative sensitivity was reported. At the 3-year follow-up, 196 restorations - 74 Class I and 122 Class II - were evaluated. Seven restorations failed (3.6%), 4 SDR-CeramX mono+ and 3 CeramX mono+ only restorations, all of which were Class II. The main reason for failure was tooth fracture, followed by resin composite fracture. The annual failure rate (AFR) for all restorations (Class I and II) was 1.2% for the bulkfilled restorations and 1.0% for the resin composite-only restorations (p > 0.05). For the Class II restorations, the AFR was 2.2% and 1.6%, respectively. The 4-mm bulk-fill technique showed good clinical effectiveness during the 3-year follow-up.

    Zirconia abutments were introduced to restore esthetic regions and showed sufficient stability to support implant restorations. Nonetheless, to date the observation periods are shorter than those of titanium abutments. To assess the survival of implant crowns supported by computer aided design-computer aided manufacturing (CAD-CAM) abutments after 3 years. Fifty-six patients were selected for this prospective clinical study. Each patient received at least 1 titanium implant for a total of 89 fixtures. A two-stage surgical technique and no additional soft or hard tissue graft were used. The implants were randomly divided into 3 groups receiving different CAD-CAM abutments: titanium, titanium nitride, and zirconia. Zirconia or metal-ceramic crowns were used as final restorations. Cementation was the baseline and the restorations were checked after 6 months, 1, 2, and 3 years, assessing any mechanical complication. Statistical analyses were performed to evaluate the 3-year success rates. Five failures were reported in the zirconia group; all the failed restorations showed fractures of the abutment connection. Four failures occurred in posterior regions and one more occurred while screwing the abutment. Titanium and titanium nitride abutments had significantly higher 3-year success rates than zirconia abutments (p < .05). Atlantis titanium and titanium nitride abutments showed optimal clinical performances after 3 years. Conversely, Atlantis zirconia abutments should be avoided to restore posterior regions. © 2016 Wiley Periodicals, Inc.

    Despite representing an important component of current dental adhesives, HEMA has been said to negatively influence the long-term stability of adhesion to dentine and enamel. The aim of this randomised clinical trial was to evaluate the 3-year clinical performance of two one-step self-etch adhesives. Thirty patients had 175 non-carious cervical lesions restored with composite (Gradia Direct Anterior, GC) using either the HEMA-rich adhesive Clearfil Tri-S Bond (C3S; Kuraray) or the HEMA-free adhesive G-Bond (GB; GC). The restorations were evaluated by two examiners at baseline, 6, 12, 24 and 36 months regarding retention, caries recurrence, marginal integrity and discoloration and post-operative sensitivity. The data were statistically analysed with GEE and McNemar tests (p<0.05). The recall rate at 6 and 12 months was 100% and decreased to 96.7% at 24 and 36 months. At 3 years, the retention rate was 93.8% for C3S and 98.8% for GB (p=0.14). A pairwise comparison showed no significant differences between the two adhesives for all the parameters evaluated, irrespective of the recall (p>0.05). After 3 years, both adhesives presented an increase in the percentage of clinically acceptable marginal discoloration (C3S: 32.9% and GB: 26.8%) normally associated to clinically acceptable marginal defects (C3S: 35.8% and GB: 26.5%). Only 1 dentine margin of a GB restoration presented a severe marginal defect (1.2%) and 1 C3S restoration presented caries recurrence. The overall 3-year clinical success rate was 92.6% for C3S and 97.6% for GB (p=0.16). Both one-step self-etch adhesives presented an equally favourable clinical effectiveness at 3 years. HEMA is a monomer frequently present in dental adhesives in order to increase their wettability and hydrophilicity. However, this monomer negatively influences hydrolytic stability and durability of the adhesive interface complex. In this 3-year clinical trial no significant difference in bonding effectiveness was noticed between a

    This study aimed to assess the clinical performance of lithium disilicate restorations supported by natural teeth or implants. Eight hundred sixty lithium disilicate adhesive restorations, including crowns on natural teeth and implant abutments, veneers, and onlays, were made in 312 patients. Parafunctional patients were included, but subjects with uncontrolled periodontitis and gingival inflammation were excluded. Veneers up to 0.5 mm thick were luted with flowable composite resin or light curing cements, while dual-curing composite systems were used with veneers up to 0.8 mm thick. Onlays up to 2 mm in thickness were luted with flowable composite resins or dual-curing composite cements. Crowns up to 1 mm in thickness were cemented with self-adhesive or dual-curing resin cements. The observational period ranged from 12 to 72 months, with a mean follow-up of 3 years. The mechanical and esthetic outcomes of the restorations were evaluated according to the modified California Dental Association (CDA) criteria. Data were analyzed with descriptive statistics. Twenty-six mechanical complications were observed: 17 porcelain chippings, 5 fractures, and 4 losses of retention. Structural drawbacks occurred mainly in posterior segments, and monolithic restorations showed the lowest number of mechanical complications. The clinical ratings of the successful restorations, both monolithic and layered, were satisfactory according to the modified CDA criteria for color match, porcelain surface, and marginal integrity. The cumulative survival rates of lithium disilicate restorations ranged from 95.46% to 100%, while cumulative success rates ranged from 95.39% to 100%. All restorations recorded very high survival and success rates. The use of lithium disilicate restorations in fixed prosthodontics proved to be effective and reliable in the short- and medium-term.

    The aim of this study was to evaluate the change of marginal bone level radiographically around three different implant systems after 3 years in function. Fifty-four patients were included and randomly assigned to three treatment groups of rough-surface implants (TiUnite, n = 37), hybrid of smooth and rough-surface implants (Restore, n = 38) and rough surface with microthread implants (Hexplant, n = 45). Clinical and radiographic examinations were conducted at the time of implant loading (baseline), 1 and 3 years after loading. A three-level mixed-effect analysis of covariance (ancova) was used to test the significance of the mean marginal bone change of the three implant groups. A total 120 of 135 implants completed the study. None of the implants failed to integrate. Significant differences were noted in the marginal bone loss recorded for the three groups (P < 0.0001). At 3 years, the rough surface with microthread implants had a mean crestal bone loss of 0.59 +/- 0.30 mm; the rough-surface implants, 0.95 +/- 0.27 mm; and the hybrid surface implants, 1.05 +/- 0.34 mm. Within the limitations of this study, rough-surface implants with microthread at the coronal part might have a long-term positive effect in maintaining the marginal bone level against functional loading in comparison with implants without these two features.

    Background/objective Internal disk disruption (IDD), an early event of lumbar disk degeneration, is the most common cause of low back pain. Since increased intradiskal pressure (IDP) is associated with symptoms and progression of disk degeneration, unloading a painful disk with an interspinous process device (IPD) is a rational treatment option. The goal of this study was to evaluate the effectiveness of dynamic stabilization with an IPD in the treatment of symptomatic IDD of the lumbar spine. Patients and methods Patients with symptomatic IDD were treated with implantation of an IPD, the device for intervertebral assisted motion (DIAM). Diagnosis of IDD was based on typical MRI finding of posterior annular high-intensity zone and positive provocative test on discography. IDP was analyzed intraoperatively. Axial back and leg pain was evaluated with visual analog scale, functional status with Oswestry Disability Index, and final clinical outcomes with Odom criteria. Data from 34 patients followed up for at least 3 years were collected. Results DIAM implantation significantly reduced IDP (n=11, P<0.0001). All 34 patients reported symptom relief. Thirty-one patients (91%) remained symptom free until the last followups. Three patients (9%) experienced recurrence of pain, of which the causes were unrelated to the IDD or surgery. Disk status at the DIAM-implanted segments remained stable. Segmental flexion/extension mobility was preserved in 27 of 30 patients with preoperative mobility. No proximal or distal adjacent segment degeneration was observed. The final clinical outcomes were excellent/good in 31 and fair/poor in three patients. Conclusion For patients with symptomatic IDD, dynamic stabilization with DIAM provides pain relief and functional improvement. The implantation maintains disk status and prevents progression of disk degeneration, without compromising segmental flexion/extension mobility or causing adjacent segment degeneration.

    Background and Objectives Cigarette smoking is a risk significant factor in coronary artery disease (CAD) and vasospastic angina (VSA). However, it is largely unknown whether smoking adds to any long-term clinical risk in VSA patients. Subjects and Methods A total of 2797 patients without significant CAD underwent acetylcholine (Ach) provocation test between November 2004 and October 2010. Patients were divided into three groups, based on the presence of coronary artery spasm (CAS) and smoking habits (non-CAS group: n=1188, non-smoking CAS group: n=1214, smoking CAS group: n=395). All CAS patients were prescribed with anti-anginal medications for at least 6 months. The incidence of major clinical outcomes and recurrent angina of these groups were compared up to 3 years. Results There were considerable differences in the baseline clinical and angiographic characteristics among the three groups, but there was no difference in the endpoints among the three groups (including individual and composite hard endpoints) such as death, myocardial infarction, de novo percutaneous coronary intervention, cerebrovascular accident, and major adverse cardiac events. However, there was a higher incidence of recurrent angina in both the non-smoking CAS group and smoking CAS group, as compared to the non-CAS group. In multivariable adjusted Cox-proportional hazards regression analysis, smoking CAS group exhibited a higher incidence of recurrent angina compared with the non-CAS group (hazard ratio [HR]; 2.46, 95% confidence interval [CI]; 1.46-4.14, p=0.001) and non-smoking CAS group (HR; 1.76, 95% CI; 1.08-2.87, p=0.021). Conclusion Cigarette smoking CAS group exhibited higher incidence of recurrent angina during the 3-year clinical follow-up compared with both the non-CAS group and non-smoking CAS group. Quitting of smoking, paired with intensive medical therapy and close clinical follow-up, can help to prevent recurrent angina. PMID:27721853

    A clinical validation study was conducted to determine the performance of a new bioactive dental cement (Ceramir C&B, Doxa Dental AB) for permanent cementation. The cement is a new formulation class, which is a hybrid material comprised of calcium aluminate and glass-ionomer components. A total of 38 crowns and bridges were cemented in 17 patients; 31 of the abutment teeth were vital and seven were non-vital. Six restorations were bridges with a total of 14 abutment teeth (12 vital/ two non-vital). One fixed splint comprising two abutment teeth was also included. Preparation parameters were recorded, as well as cement characteristics such as working time, setting time, seating characteristics, and ease of cement removal. Baseline data were recorded for the handling of the cement, gingival inflammation, and pre-cementation sensitivity. Post-cementation parameters included post-cementation sensitivity, gingival tissue reaction, marginal integrity, and discoloration. All patients were seen for recall examinations at 30 days and 6 months. Fifteen of 17 subjects and 13 of 17 patients were also available for subsequent comprehensive 1- and 2-year recall examination, and 13 patients were available for a 3-year recall examination. Restorations available for the 3-year recall examination included 14 single-unit full-coverage crown restorations, four three-unit bridges comprising eight abutments, and one two-unit splint. Three-year recall data yielded no loss of retention, no secondary caries, no marginal discolorations, and no subjective sensitivity. All restorations rated excellent for marginal integrity. Average visual analogue scale (VAS) score for tooth sensitivity decreased from 7.63 mm at baseline to 0.44 mm at 6-month recall, 0.20 mm at 1-year recall, and 0.00 mm at 2- and 3-year recall. Average gingival index (GI) score for gingival inflammation decreased from 0.56 at baseline to 0.11 at 6-month recall, 0.16 at 1-year recall, 0.21 at 2-year recall, and 0.07 at 3

    Tipe 1 T-helper cells are of importance in development of multiple sclerosis (MS). Copaxone (TEVA, Israel) is one of the preventive drugs, which modifies T-helpers activity. Thirty-three patients with MS were treated by copaxone for 2 years and 13 patients--for 3 years. Clinical and immunological parameters were examined: amount of CD3+, CD4+, CD8+, CD16+, CD22+, CD95+, CD25+ lymphocytes, HLA-D+ cells, IgG, IgA, IgM and phagocytosis. During the treatment course, mean rate of relapses decreased from the pretreatment value from 1.26 +/- 0.11 to 0.59 +/- 0.11 in the first year and 0.28 +/- 0.07 in the second one. After 3 years no relapses were observed in 13 patients. Relapse rate was the highest in the first 3-6 months. But after 3 months there was an increase of CD22+ cells that persisted for all the period of the study. After a year of the treatment, a level of IgM, IgG, IgA and CD95+ cells has raised significantly, with decreasing of a number of CD4+ and CD8+ cells. The authors suggest that immunological shift is related to mechanism of copaxone action determining its positive effect i.e. reducing of frequency of MS relapses.

    Nontuberculous mycobacteria (NTM) are being increasingly isolated in clinical laboratories and present technical and therapeutic challenges. In the present study, we report our experience with the identification of NTM received from 12 Lisbon hospitals over a 3-year period using GenoType Mycobacterium (CM/AS) assays (HAIN Lifescience GmbH, Nehren, Germany). Together, the two kits identified 96.6% of all NTM isolates tested. Among the 18 NTM species identified, Mycobacterium avium complex was the most frequent, although it accounted for only 34% of all NTM. Introducing these methods for the rapid identification of NTM highlights the importance of NTM as potential pathogens and assisted the selection of adequate therapy.

    To avoid the necessity of a removable provisional prosthesis, and therefore preserve the patient's functional outcome, esthetics, and quality of life, a clinical protocol was developed to approach periodontally compromised patients presenting a full-arch irreversibly lost dentition: full-arch extraction and immediate replacement with a provisional acrylic resin implant-supported fixed partial denture (FPD). A total of 23 periodontally compromised patients (11 women, 12 men; 4 smokers, 4 controlled diabetics) were included in this study. Pretreatment casts were taken and vertical dimension of occlusion was determined. In most patients, 6 Straumann implants were distributed along the arch according to the surgical guide or bone availability, with the most distal ones in the maxilla slightly tilted so they could emerge more distally. A total of 168 implants (146 Straumann, 10 Nobel Biocare, 8 Biomet 3i, and 4 Lifecore) were placed (83 in the maxilla, 85 in the mandible). Of those in the maxilla, 74 were loaded immediately (implant stability quotient mentor [ISQm] > 70) and 9 placed with delayed loading (ISQm =/< 70). Of the 85 implants placed in the mandible, all were loaded immediately (ISQm > 70). If an FPD had not been fabricated already, impressions were taken during surgery to do so. The prosthesis was then adapted (cemented or screwed) to the 6 implants within the first 48 hours postsurgery. After 2 months, definitive impressions were taken, and a definitive porcelain-fused-to-metal implant-supported 12-element FPD was fabricated and cemented or screwed to all 6 implants. Of the 168 implants, 108 were immediate implants and 159 immediately loaded. Only 2 implants (1 in the mandible, 1 in the maxilla) did not osseointegrate. This yields a 3-year cumulative survival rate of 98.74% (98.65% in the maxilla, 98.82% in the mandible). From a total of 26 immediately loaded prostheses (12 in the maxilla, 14 in the mandible), 6 were cemented and 20 screw-retained. The 3

    The Wilmington Senior Center developed a 3-year multidisciplinary health and wellness initiative entitled The Time of Your Life to promote healthy aging for participants attending countywide senior centers. The purpose of this paper is to describe the development and implementation of the evaluation methodology and outcomes of this senior health and wellness project that consisted of 11 programs in total. Long-term programming can present several challenges in both implementation and evaluation, but assessing outcomes is critical to documenting program value and accountability. Participant-completed surveys and post-series focus groups were utilized as the evaluation tools. Our findings indicate that the program's objectives of increasing knowledge and motivating adoption or maintenance of a healthy lifestyle were met to varying degrees, while a third objective of assessing the usefulness of resources to inform health-related decisions was unable to be evaluated due to the cross-sectional nature of the data collection. Post-series focus groups indicated that topics of most interest to seniors were money management, medications and staying mentally and physically fit. The evaluations showed that long-term programming, while challenging, can be a successful and sustainable format for senior health education.

    An in vivo comparison was made of three different types of restorative resins: a conventional composite resin, a chemically cured microfilled resin, and a small-particle, glass-filled, visible light-cured composite resin. Twenty-eight sets of three restorations were placed 20 patients and examined using the Ryge rating system. All resins performed well and were not significantly different from one another at 1 year. After 3 years, all materials were considered satisfactory, but the conventional composite resins had significantly more surface roughness than did the other resins. Each of the resin materials also declined in color match after 3 years.

    The Objective Structured Clinical Examination (OSCE) appears to be an effective alternative for assessing not only medical knowledge, but also clinical skills, including effective communication and physical examination skills. The purpose of the current study was to implement an OSCE model in a geriatrics fellowship program and to compare the instrument with traditional essay examination. Seventy first- and second-year geriatric fellows were initially submitted to a traditional essay examination and scored from 0 to 10 by a faculty member. The same fellows subsequently underwent an OSCE with eight 10-minute stations covering a wide range of essential aspects of geriatric knowledge. Each OSCE station had an examiner responsible for its evaluation according to a predefined checklist. Checklist items were classified for analysis purposes as clinical knowledge items (CKI) and communication skills items (CSI); fellow responses were scored from 0 to 10.Although essay examinations took from 30 to 45 minutes to complete, 180-200 minutes were required to evaluate fellows using the proposed OSCE method. Fellows scored an average of 6.2 ± 1.2 on the traditional essay examination and 6.6 ± 1.0 on the OSCE (P < .001). Subanalyses of OSCE scores indicated that average performance on CKI was lower than the average on CSI (6.4 ± 1.1 vs. 8.4 ± 1.1; P < .001). Fellow performance on the essay examination was similar to their performance on CKI (P = .13). Second-year fellows performed better than first-year fellows on the essay examination (P < .001) and CKI (P = .05), but not on CSI (P = .25).The OSCE was successfully implemented as an educational strategy during a geriatrics fellowship program. Combining different testing modalities may provide the best assessment of competence for various domains of knowledge, skills, and behavior. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

    Children with epilepsy attending a condition-specific overnight camp were evaluated for behavioral changes over 3 consecutive years, using a modification of the Vineland Adaptive Behavioral Scale. Trained counselors completed pre- and postcamp assessments for each camper. Repeated-measures MANOVA was used to analyze effects of the camp experience for each year, with respect to gender and age. Repeated-measures ANOVA was conducted to evaluate long-term effects from year-to-year comparisons for return campers, following three successive camp experiences. A significant change in social interaction was observed over 3 years. Despite some decline at the start of camp in consecutive years, the overall trend for return campers suggests a positive cumulative impact of continued camp participation, with improvements in the domains of social interaction, responsibility, and communication. A condition-specific camp designed for children with epilepsy can improve adaptive behaviors and social interactions. Overall net gains appear to increase over time, suggesting additional benefits for return campers.

    We conducted a 3year intervention to increase awareness and adoption of eight more profitable nursery crop production practices that reduced certain traumatic and musculoskeletal injury hazards. We disseminated information to nursery managers across seven states using information channels they were known to rely on (e.g. trade publications, public events, university Extension, other managers). We evaluated rolling, independent, probability samples (n=1200) with mail questionnaires before the intervention and after each of 3 intervention years. We also evaluated samples (n=250) from a comparison group of New Zealand nursery managers. The intervention was associated with increased awareness of four of the eight practices among US managers after year 3 compared to their baseline: zippers (20 vs. 32%, p

    This study examines the treatment outcomes of 144, 6–11 year-old, clinically referred boys and girls diagnosed with Oppositional Defiant Disorder (ODD) or Conduct Disorder (CD) who were randomly assigned to a modular-based treatment protocol that was applied by research study clinicians either in the community (COMM) or a clinic office (CLINIC). To examine normative comparisons, a matched sample of 69 healthy control children was included. Multiple informants completed diagnostic interviews and self-reports at six assessment timepoints (pretreatment to 3-year follow-up) to evaluate changes in the child’s behavioral and emotional problems, psychopathic features, functional impairment, diagnostic status, and service involvement. Using HLM and logistic regression models, COMM and CLINIC showed significant and comparable improvements on all outcomes. By 3-year follow-up, 36% of COMM and 47% of CLINIC patients no longer met criteria for either ODD or CD, and 48% and 57% of the children in these two respective conditions had levels of parent-rated externalizing behavior problems in the normal range. We discuss the nature and implications of these novel findings regarding the role of treatment context or setting for the treatment and long-term outcome of behavior disorders. PMID:19221871

    Purpose. Nowadays, the advancements in direct metal laser sintering (DMLS) technology allow the fabrication of titanium dental implants. The aim of this study was to evaluate implant survival, complications, and peri-implant marginal bone loss of DMLS implants used to support bar-retained maxillary overdentures. Materials and Methods. Over a 2-year period, 120 implants were placed in the maxilla of 30 patients (18 males, 12 females) to support bar-retained maxillary overdentures (ODs). Each OD was supported by 4 implants splinted by a rigid cobalt-chrome bar. At each annual follow-up session, clinical and radiographic parameters were assessed. The outcome measures were implant failure, biological and prosthetic complications, and peri-implant marginal bone loss (distance between the implant shoulder and the first visible bone-to-implant contact, DIB). Results. The 3-year implant survival rate was 97.4% (implant-based) and 92.9% (patient-based). Three implants failed. The incidence of biological complication was 3.5% (implant-based) and 7.1% (patient-based). The incidence of prosthetic complication was 17.8% (patient-based). No detrimental effects on marginal bone level were evidenced. Conclusions. The use of 4 DMLS titanium implants to support bar-retained maxillary ODs seems to represent a safe and successful procedure. Long-term clinical studies on a larger sample of patients are needed to confirm these results.

    The aim of this study was to evaluate etiology, types of traumatic dental injuries, treatment and to determine the incidence of complications according to dental injuries in patients who referred to Yeditepe University, Faculty of Dentistry, Istanbul, Turkey. The study was based on the clinical data of the 161 traumatized teeth in 92 patients. WHO classification slightly modified by Andreasen & Andreasen for dental trauma was used. The causes and localization of trauma, traumatized teeth classification, treatment and complications were evaluated both primary and permanent teeth. The distribution of complications according to diagnosis and treatment of the injured teeth were evaluated. Of 35 (38%) girls and 56 (72%) boys with a mean age 7.6 +/- 3.5 (ranging 1-14.2) participated to study and the mean followed up was 1.72 +/- 1.28 years (ranging 0.10-3.8 years). From the 161 affected teeth, 69 (42.9%) were in primary teeth and 92 (57.1%) in permanent teeth. The highest frequency of trauma occurred in the 6-12 year age group. Overall boys significantly outnumbered girls by approximately 1:1.6. The most common type of injury in the primary and permanent teeth was seen as luxation (38%) and enamel fracture (20%) of the maxillary central incisors, respectively. Falls were the major sources of trauma both the primary (90%) and the permanent teeth (84%). In the primary dentition, the most common type of soft tissue injury is contusion (62.5%) and in the permanent dentition, it is laceration (49%). The most of the treatment choice was determined as examination only and extraction in primary teeth (58 and 24.6%, respectively) while it was applied as restoration and pulpectomy in permanent teeth (31.5 and 18.5%, respectively). Complications were recorded on 37 teeth (23%) with a most common type of necrosis (10.5%) and dental abscess (7.4%). Necrosis was more frequent in luxation whereas dental abscess were in crown fracture with pulpal involvement in both dentitions. The

    To evaluate the efficacy of a conservative treatment to prevent the progression of caries using an infiltrant on non-cavitated pit and fissures. This controlled clinical trial selected 23 volunteers with clinically and radiographically non-cavitated occlusal caries among patients presenting a "rather low" to "very high" caries risk. Eighty-six teeth were randomly divided into two experimental groups: teeth receiving a commercial pit-and-fissure sealant (Alpha Seal-DFL) and contralateral teeth receiving Icon infiltrant (DMG). Caries progression was monitored by clinical (laser fluorescence caries detection) and radiographic examination at 12-month intervals over a period of 3 years of monitored caries progression. Probing the sealing materials to detect areas of retention was also used to evaluate marginal integrity. Statistical analysis showed no difference in caries progression using laser fluorescence caries detection when both materials were compared, regardless of the evaluation times (p>0.05). No significance was observed when the marginal sealant integrity of both materials was compared, regardless of the evaluation time (p<0.05). Marginal integrity significantly reduced after 1 year for both materials (p<0.05), but remained stable after 2 and 3 years of evaluation, compared with 1-year results (p>0.05). SEM analysis exhibited a more homogeneous sealing for the infiltrant than obtained by the sealant. The infiltrant was effective to prevent the caries progression in non-cavitated pit-and-fissures after 3 years of clinical evaluation, comparable with the conventional sealant. The infiltrant also presented better results in terms of caries progression at the 3-year evaluation time using the radiographic analysis.

    We report a 3-year analysis (1986 to 1989) of the management of 63 home parenteral nutrition patients, 40 with short-bowel syndrome and 23 with chronic intestinal obstruction with or without intestinal resection. Intravenous fluid requirements varied from 0.9 to 6 L/day, and the content of glucose varied between 46 and 531 g/day, protein varied from .0 to 85 g/day, fat from .0 to 100 g/day, sodium from 37 to 695 mEq/day, potassium from 30 to 220 mEq/day, chloride from 60 to 760 mEq/day, and acetate from 0 to 200 mEq/day. Body weight was normalized and well maintained in the majority of patients, but using the strict definition of deficiency as the presence of one abnormal value during 3 years, more than half had abnormal plasma chloride, glucose, alkaline phosphatase, serum glutamic oxaloacetic transaminase, total protein, albumin, selenium, and iron concentrations, and more than a third had low calcium, magnesium, vitamin D, and vitamin C levels. Normochromic anemia was seen in 73% and high blood creatinine associated with low urine volumes in 42%. Most (78%) returned to relatively normal lifestyles, but employability was occasionally impaired by loss of third-party insurance coverage resulting from a therapy that may cost $100,000 per year. Overall mortality was low (5% per year), but 73% needed readmission to hospital, mainly for suspected catheter sepsis. The results indicate that home parenteral nutrition has allowed many patients to survive gut failure and return to work but problems with chronic fluid, electrolyte and micronutrient deficiencies, catheter sepsis, and insurance coverage often restrict optimal rehabilitation.

    This longitudinal randomized controlled clinical trial evaluated composite resin inlays for clinical acceptability in single- or multisurface preparations and provides a survey of the results up to 3 years. Twenty-one dental students placed 75 Artglass (Heraeus Kulzer) and 80 Charisma (Heraeus Kulzer) composite resin inlays in Class 1 and 2 preparations in posterior teeth (89 adults). Clinical evaluation was performed at baseline and up to 3 years by two other dentists using modified USPHS criteria. A total of 89.8% of Artglass and 84.1% of Charisma inlays were assessed as clinically excellent or acceptable with predominating Alfa scores. Up to the 3-year recall, five Artglass and 10 Charisma inlays failed mainly because of postoperative symptoms, bulk fracture, and loss of marginal integrity. No significant differences between composite resin materials could be detected at 3 years for all clinical criteria (P > .05). The comparison of restoration performance with time within both groups yielded a significant increase in marginal discoloration (P < .05) and deterioration of marginal and restoration integrity (P < .05) for both inlay systems. However, both changes were mainly effects of scoring shifts from Alfa to Bravo. No significant differences (P > .05) were recorded comparing premolars and molars. Small inlays showed significantly better outcome for some of the tested clinical parameters (P < .05). Clinical assessment of Artglass and Charisma composite resin inlays exhibited an annual failure rate of 3.4% and 5.3% that is within the range of published data. Indirect composite inlays are a competitive restorative procedure in stress-bearing preparations.

    Total joint arthroplasty (TJA) is one of the most successful operations. There is little in the literature regarding weight change following TJA, particularly in a young cohort. Retrospective analysis of 181 primary total hip arthroplasty (THA) and 185 primary total knee arthroplasty (TKA) patients was conducted. We reviewed preoperative and post-operative weights and post-operative body mass index at 3 and 6 months, 1 year, 2 and 3 years. We evaluated expected versus actual weight gain, and performed subgroup analyses of obese versus non-obese patients and active duty versus civilian patients. We used a minimal clinically meaningful weight change from baseline of ≥5%. One hundred and fifty-one (41.3%) patients were active duty military service members with the mean age of 53 ± 11.1 years. In TKA patients, statistically significant differences were found in mean weights at 3 months (-1.8%, P ≤ 0.0001) and 2 years (+1.9%, P = 0.0006). In THA patients, statistically significant weight gains were found at 6 months (+1.1%, P = 0.006). For obese TKA patients, significant weight changes were observed at 3 months (-2.5%, P ≤ 0.0001), and none in the obese THA group. There were no statistical or clinically meaningful weight changes in the non-obese TKA or THA groups. There was a clinically meaningful weight gain in active duty TKA patients at 3 years (5.18%, P = 0.17). Despite a theoretical ability to lose weight following TJA, patients maintain their preoperative weight following TJA. We found a clinically meaningful weight gain at 3 years post-operatively only in active duty TKA patients. Overall, however, we found no clinically significant weight changes following TJA at 3-year follow-up. Published 2016.

    SUMMARY Aim. In this preliminary study, the 3-year radiological outcomes of Osseospeed implant-supported fixed complete or partial prostheses made with two different laboratory protocols were compared. Methods. A convenience sample of 34 patients, who were either partially or completely edentulous in either jaw, were randomly assigned to two groups, of 17 patients each, using either a traditional laboratory protocol (control group) or the Cresco one (test group). The study’s objective was an assessment of marginal bone loss around implants, measured on intraoral radiographs at 3-year follow-up. Results. None of the implants inserted was lost during the study and radiological measurements of marginal bone level changes revealed that the mean marginal bone loss was respectively 0,73±0,33mm for test group and 0,88±1,13mm for control group. The differences between test and control groups were not statistically significant. Conclusion. This preliminary study did not demonstrate statistically significant differences in marginal bone loss around implant-prostheses prepared with the two different laboratory protocols, over the 3-year observational period.

    Situated and sociocultural perspectives on learning indicate that the design of complex tasks supported by educational technologies holds potential for dental education in moving novices towards closer approximation of the clinical outcomes of their expert mentors. A cross-faculty-, student-centred, web-based project in operative dentistry was established within the Universitas 21 (U21) network of higher education institutions to support university goals for internationalisation in clinical learning by enabling distributed interactions across sites and institutions. This paper aims to present evaluation of one dental faculty's project experience of curriculum redesign for deeper student learning. A mixed-method case study approach was utilised. Three cohorts of second-year students from a 5-year bachelor of dental surgery (BDS) programme were invited to participate in annual surveys and focus group interviews on project completion. Survey data were analysed for differences between years using multivariate logistical regression analysis. Thematic analysis of questionnaire open responses and interview transcripts was conducted. Multivariate logistic regression analysis noted significant differences across items over time indicating learning improvements, attainment of university aims and the positive influence of redesign. Students perceived the enquiry-based project as stimulating and motivating, and building confidence in operative techniques. Institutional goals for greater understanding of others and lifelong learning showed improvement over time.

    Evaluation of differences in the clinical performance and crestal bone levels between implants restored with single crowns with platform-matched or platform-switched abutments after 3 years. The study enrolled adult patients missing two or more adjacent teeth in the posterior mandible with natural teeth mesial to the implant site. Randomization followed open-flap implant insertion and the corresponding matching or switching healing abutments placed at surgery. Conventional loading was made with cemented crowns. Clinical follow-up took place annually after loading up to 3 years. Bone level changes were measured in standardized radiographs as the variation in crestal bone from one evaluation to the next. Sixty-three patients with a total of 135 implants (66 platform matching, 69 platform switching) were analysed. From surgery to 36 months, mean bone loss was 0.28 ± 0.56 mm for the platform-switching group and 0.68 ± 0.64 mm for the platform-matching group. A statistically significant difference was found between groups (p = 0.002) with an estimate of 0.39 mm (0.15-0.64, 95% CI) in favour of platform switching. After 3 years, platform-switching restorations showed a significant effect in the preservation of marginal bone levels compared to platform-matching restorations. © 2016 The Authors.

    This prospective clinical study evaluated the sealant retention rate and caries-preventive efficacy of two fissure sealing techniques over a 3-year period. Subjects (87) aged between 6.5 and 11.5 years were enrolled into two groups. In Group I (41 subjects), a resin-based fissure sealant (Fissurit FX, VOCO, Germany) was placed on all four sound permanent first molars (FPM-164 teeth) of each subject and in Group II (46 subjects) on 4 caries-free premolars (P1-2 182 teeth),using the following adhesives systems: Optibond FL (Kerr, USA), Optibond Solo plus (Kerr, USA), Prompt-L-Pop (3 M ESPE, USA) or the conventional acid-etch technique. Sealed teeth were evaluated at baseline, 6, 12, 18, 24 and 36-month intervals with regard to retention and new caries development. Sealant retention was scored as: (1) complete retention; (2) partial loss; (3) complete loss of sealant. Wilcoxon-signed rank test was used to analyse the data. The complete retention rate was: Optibond FL/sealant 80.01-82.92 %, Optibond Solo plus/sealant 73.78-74.27 %, Prompt-L-Pop/sealant 42.84-53.65 % versus acid-etch technique 62.86-71.44 % on FPM and P1-2 (p < 0.05). The fissure caries incidence rate was: Optibond FL/sealant 2.43-2.85 %, Optibond Solo plus/sealant 2.85-4.76 %, Prompt-L-Pop/sealant 24.40-34.28 % versus acid-etch technique 16.66-17.14 % (p < 0.05) on FPM and P1-2. A statistically significant difference in sealant retention rate was observed between FPM and P1-2, using the self-etching adhesive system Prompt-L-Pop and acid-etch technique. It may be concluded that the use of adhesive systems Optibond FL and Optibond Solo plus yielded better fissure sealing performance.

    Previously, we demonstrated that the urine proteome signature of patients with rheumatoid arthritis (RA) reflects inflammation-related cellular processes. Here, we measured interleukin (IL)-6, IL-8, and chemokine ligand 2 (CCL2) concentrations in the urine of RA patients and prospectively investigated their role in predicting RA activity and prognosis. One hundred seventy-three RA patients and 62 non-RA controls were recruited. Urinary IL-6, CCL2, and IL-8 levels were elevated in RA patients and correlated well with disease activity. Urinary IL-6 level at presentation was an independent risk factor of radiographic progression at 1 and 3 years. High urinary IL-6 level increased the risk ratio of radiographic progression by 2.9-fold, which was comparable to high serum CRP. Moreover, combination of urinary IL-6 and serum CRP measures synergistically increased the predictability of radiographic progression. In a subgroup with normal ESR, patients with the highest tertile of urinary IL-6 were at 6.4-fold greater risk of radiographic progression. Conclusively, high urinary IL-6 level at presentation is an independent risk factor for radiographic progression of RA, reflecting disease activity. Urinary IL-6 in combination with serum CRP may be a useful parameter for estimating RA prognosis. PMID:27731382

    Different means are available for self-performed oral hygiene. The aim of this study was to evaluate the clinical and microbiologic effects of a preventive homecare program including the combined use of a powered toothbrush and a triclosan/copolymer-containing dentifrice. A total of 160 adult subjects without signs of destructive periodontal disease were recruited for this 3-year randomized controlled trial. The subjects were assigned to a homecare program using an oscillating/rotating powered toothbrush and a triclosan/copolymer/fluoride-containing dentifrice (test) or a manual toothbrush and a standard fluoride-containing dentifrice (control). Supragingival polishing and reinforcement of homecare procedures were provided every 6 months. Plaque, bleeding on probing (BOP), and probing depth (PD) were scored at baseline and after 1, 2, and 3 years. Subgingival plaque samples were taken from the mesial aspect of each tooth at baseline and after 1, 2, and 3 years and were analyzed for their content of 40 bacterial species using checkerboard DNA-DNA hybridization. All data analyses were based on "intention-to-treat" with the subject as the statistical unit. Compared to baseline, no significant changes in clinical parameters were observed during the 3 years, except for a reduction in the mean PD at the 2- and 3-year follow-up examinations (P <0.05). No significant differences were found between the two groups with regard to plaque, BOP, or PD or in the mean counts of the 40 species at any time point. The study failed to prove additional benefits of the combined use of a powered toothbrush and a triclosan/copolymer-containing dentifrice in adult subjects without signs of destructive periodontal disease.

  2. Mixed hepatoblastoma and teratoma of the liver in a 3-year-old child: a unique combination and clinical challenge

    PubMed Central

    2009-01-01

    Primary liver tumors in children are rare with malignant hepatoblastoma being the most common neoplasm. In this report, we describe the diagnosis and clinical management of a large liver tumor in a 3-year-old child that displayed the features of both, conventional hepatoblastoma and malignant teratoma. Pathological assessment on a pre-operative bioptical specimen showed an immature teratoid tumor with no area of hepatoblastic differentiation present. Histological and immunhistological examination of the resected tumor specimen additionally showed tumor areas of very different differentiation pattern intermixed with each other, namely areas of hepatoblastoma-typical and neuroblastoma-like morphology as well as areas of rhadomyosarcomatous differentiation. After chemotherapy the tumor size increased and an extended right hemihepatectomy was performed. Post-operatively, the general condition of the child improved and adjuvant chemotherapy was started two weeks later. 36 months after initial diagnosis the patient is healthy, in good general condition, and without any sign of residual tumor disease. Overall, we describe the diagnosis and clinical management of a large liver tumor in a 3-year-old child that displayed the features of both, conventional hepatoblastoma and malignant teratoma and was designated as mixed hepatoblastoma and teratoma. Though mesenchymal tumor portions can occur within hepatoblastomas, most commonly osteoid or chondroid, our case is different as it presents a large spectrum of mesenchymal and epithelial differentiation pattern in most of the lesion.

    The promotion of household water treatment and handwashing with soap has led to large reductions in child diarrhoea in randomized efficacy trials. Currently, we know little about the health effectiveness of behaviour-based water and hygiene interventions after the conclusion of intervention activities. We present an extension of previously published design (propensity score matching) and analysis (targeted maximum likelihood estimation) methods to evaluate the behavioural and health impacts of a pre-existing but non-randomized intervention (a 3-year, combined household water treatment and handwashing campaign in rural Guatemala). Six months after the intervention, we conducted a cross-sectional cohort study in 30 villages (15 intervention and 15 control) that included 600 households, and 929 children <5 years of age. The study design created a sample of intervention and control villages that were comparable across more than 30 potentially confounding characteristics. The intervention led to modest gains in confirmed water treatment behaviour [risk difference = 0.05, 95% confidence interval (CI) 0.02-0.09]. We found, however, no difference between the intervention and control villages in self-reported handwashing behaviour, spot-check hygiene conditions, or the prevalence of child diarrhoea, clinical acute lower respiratory infections or child growth. To our knowledge this is the first post-intervention follow-up study of a combined household water treatment and handwashing behaviour change intervention, and the first post-intervention follow-up of either intervention type to include child health measurement. The lack of child health impacts is consistent with unsustained behaviour adoption. Our findings highlight the difficulty of implementing behaviour-based household water treatment and handwashing outside of intensive efficacy trials.

    In this retrospective study, the investigators examined blood cultures from patients that had been diagnosed with bacteremias over a 3-y period. The study was conduced at Kocatepe University Hospital (Middle Anatolia, Turkey). Blood samples that arrived at the university's microbiology laboratory between 2002 and 2005 were evaluated retrospectively. These samples were classified as contamination, false positivity, community-acquired bacteremia (CAB), or hospital-acquired bacteremia (HAB). Patient age and sex, foci of bacteremia, present comorbidities, predisposing factors, pathogens, and mortality rates were evaluated. A total of 1783 blood cultures that had been drawn from 1441 patients during this 3-y period were examined retrospectively. Of 354 positive isolates, 61 (17.2%) were CABs and 293 (82.8%) were HABs. In HABs, the most commonly isolated microorganisms were Staphylococcus aureus (37.5%), coagulase-negative staphylococci (29.7%), and Escherichia coli (10.2%); in CABs, the most commonly isolated microorganisms were S aureus (29.5%), Brucella spp (26.2%), and E coli (24.6%). Crude mortality rates were determined to be 15.2% for HABs and 12.7% for CABs. This study yielded data on the most common foci of bacteremia, microbiologic factors, and the epidemiology associated with HABs and CABs. It is hoped that these data will enhance empirical antibiotic therapeutic approaches, thereby preventing delays in treatment and decreasing mortality rates associated with bacteremias.

    The aim of this paper is to publish results from the Department of Ophthalmology, Regional hospital Pardubice, Czech Republic, E.U., obtained at our workplace during the period 2003 to 2005 for the all-European study with the title: European Cataract Outcome Study. European Cataract Outcome Study is international all-European study monitoring availability of the cataract surgery in different parts of the Europe and it follows up the quality of the cataract surgeries in separately entered departments. Its goal is to incite the development of cataract surgery and extend new technologies of cataract surgery and use the findings for determining indication and timing of the surgery for the evaluation of the profit the patients have from cataract surgery. This study evaluates yearly the results of primary cataract surgery provided during one month of the year--October. The study has been proceeding since 1995; we have been participated in it since 2003 and cooperated up to the present day. In the first part of study, there are followed up the basic demographic data with pre-operative investigation and course of the cataract surgery, in the second part results of post-operative investigations during 6 months after the surgery. The patients in our department are in entire majority operated in local subconjunctival anesthesia by means of phacoemulsification with implanted foldable lenses, whose number rises along assessed years from 51% to almost 100% of cases. European tendency is out-patient cataract surgery; in our department, there're patients hospitalized in 60-62.9% of cases. During three years we have noted attendance of associated disorders in 28-45% of cases. The post-operative best-corrected visual acuity 0.5 and better up to 6 months after the surgery is in 86-90% of cases.The intended postoperative refraction was from -0.40 to -0.48 diopters (dpt), the final post-operative error from the planned refraction was 1.2 dpt. The average of induced astigmatism is 0

    The 'Community Action for Preventing HIV/AIDS Project' was implemented in four provinces in Cambodia (2001-04) to support a comprehensive set of HIV prevention efforts. Implementation was strictly monitored in terms of inputs, outputs and outcomes. We examine changes in these variables during the project period to assess the extent to which they were related to the project. Inputs and outputs were monitored regularly by supervision and quarterly project reports. Baseline and follow-up surveys were conducted on 10 target groups to measure changes in outcome indicators related to sexual risk behaviours, uses of HIV voluntary counselling and testing (VCT), self-reported sexually transmitted infections (STIs) and other indicators. The analyses use data from surveys and from project monitoring. Spending on HIV-related work at provincial level increased markedly, including investments in VCT, STI facilities and staff training. Yearly expenditure increased about 7-fold compared with years immediately preceding the project. VCT centres increased from 3 to 12, numbers of counsellors from 10 to 27, and numbers of client visits more than doubled. STI laboratory facilities increased from 0 to 6 with coverage of STI check-ups among sex workers increasing from 70% to 93% and a decline in men attending STI clinics. The survey results indicate significant changes in a number of major outcome indicators such as consistent condom use related to sex work (>80%), HIV testing and counselling after HIV tests, especially among police (42 to 72%, P < 0.001) and brothel-based sex workers (48 to 89%, P < 0.001). Self-reported STIs declined in most groups. Finally, the programmatic systems for planning, managing and monitoring implementation of activities at both central and provincial level, as well as technical guidelines, developed under the project have become the standard for the national programme. In conclusion, the project appears to have been comprehensive and a number of favourable

    The aim of this randomized clinical study was to compare the 3-year clinical outcome of metal-ceramic fixed dental prostheses (MC-FDPs) and zirconia all-ceramic fixed dental prostheses (AC-FDPs) replacing a posterior tooth. A sample of 34 patients with a missing posterior tooth were randomly chosen to receive either a MC-FDP (n = 17) or an AC-FDP (n = 17). The FDPs were evaluated at baseline and yearly until 3 years after cementation. They were assessed using the California Dental Association assessment system. Periodontal parameters were measured at the abutment teeth, and the contralateral teeth served as control. The statistical unit was the FDP/patient. The survival rates for MC-FDPs and AC-FDPs were 100%. The success rate was 76% and 71% for MC-FDPs and AC-FDPs, respectively. Three technical complications were observed in the MC-FDP group and five in the AC-FDP group, all chipping fractures of the ceramic veneer. Furthermore, one biologic complication in the MC-FDP group (an apical lesion) was observed. No framework fractures occurred. All patients had optimal oral hygiene and showed no bleeding on periodontal probing at any of the recalls. Only minor changes in the periodontal parameters were observed during the 3 years of observation. Three-unit posterior MC-FDPs and AC-FDPs showed similar high survival rates and acceptable success rates after 3 years of function, and ceramic veneer chipping fracture was the most frequent complication for both types of restorations.

    To present the 3-year experience of the early intervention in psychosis (EIP) service implementation of the 1st Psychiatric University Clinic in Athens. An overview of: (1) the purpose of our service, (2) the referral network, (3) the selection criteria, (4) the diagnostic procedures, (5) the therapeutic interventions and (6) the research activities. The service was established in 2012 and developed gradually aiming to provide information, early detection, treatment and support to people aged 15 to 40 years with psychotic manifestations, who are either at increased risk of developing psychosis (at-risk mental state [ARMS]) or with first episode psychosis (FEP). In order to assess individuals with ARMS, we used the comprehensive assessment of at-risk mental states interview and the Social and Occupational Functioning Assessment Scale The duration of untreated psychosis was estimated by using the Nottingham Onset Schedule. So far we have had 65 referrals, of which 26 were ARMS and 17 FEP. Based on the individual needs, they were offered psychotherapeutic and/or pharmacological treatment. After 3 years, the rate of transition to psychosis was 19.2% and the rate of psychosis relapse was 11.7%. The implementation of our service has had positive results, enabling young people with early psychosis to receive prompt and effective care. The rates of transition to psychosis are the first to be published from a Greek EIP service. Further development of our referral network and inter-hospital collaboration will allow us to address the needs of a wider part of the population. © 2016 John Wiley & Sons Australia, Ltd.

    Comparison of current and estimated premorbid IQ in schizophrenia suggests that there are subgroups with low IQ, deteriorated IQ (DIQ), or preserved IQ and that this is established by psychosis onset. There are no controlled studies examining the trajectory of these IQ subgroups longitudinally or their relationship with clinical and social outcomes. Of 129 individuals with first-episode schizophrenia or schizoaffective disorder, 25% showed stable low IQ, 31% showed stable IQ in the average/high range, and 44% demonstrated intellectual deterioration by 10 points or more. Patients in the low and deteriorated groups were equally impaired on tests of memory and executive function compared with the preserved average/high-IQ group and controls and showed more negative and disorganization symptoms than the preserved average/high-IQ group. Sixty patients and 27 controls were assessed again 1 and 3 years later. There was no evidence that those with IQ deterioration at baseline continued on a declining cognitive trajectory or that those with preserved average/high IQ experienced subsequent IQ decline. The low IQ group showed no change in IQ, whereas both the DIQ and the preserved IQ groups improved. However, the rate of improvement of these 2 subgroups was no greater than that of the healthy controls, suggesting that this reflected practice effects. Both the low and the deteriorated groups had longer index admissions, more core negative symptoms, and worse occupational outcomes at 3 years. These data suggest that following psychosis onset, IQ is stable and that it is IQ at psychosis onset rather than premorbid IQ predicts a more severe illness.

    Purpose: To provide the types, frequency and clinical information on common cranial nerve palsies seen at the Eye Clinic at the University of Port Harcourt Teaching Hospital. Materials and Methods: A chart review was performed of patients who presented with cranial nerve palsy at the Eye Clinic over a 3-year period (January 2009-December 2011). Data were collected on age, sex, type of cranial nerve palsy, a history of systemic disease such as diabetes mellitus (DM), hypertension and cerebrovascular disease. Exclusion criteria included medical charts with incomplete data. Data was analyzed using Epi-info Version 6.04D. Statistical significance was indicated by P < 0.05. Results: Twenty-four patients had cranial nerve palsies. There were 11 males and 13 females with a mean age of 34.50 ± 18.41 years. Four patients (26.6%) had exotropia while three patients (20%) had esotropia. Complete ophthalmoplegia was noted in two patients (13.3%). The 3rd and 6th cranial nerves were affected in seven patients each (29.2%) and five patients (20.8%) had 7th cranial nerve palsy. Approximately 38% of patients with cranial nerve palsies had systemic disorders (16.7% systemic hypertension; 12.5% DM). The relationship between cranial nerve palsy and systemic disorder was statistically significant (P < 0.01). Conclusion: This is the first study in the literature on ocular cranial nerve palsies in Southern Nigeria. Third and sixth cranial nerve palsies were the most common cases to present to the University of Port Harcourt Teaching Hospital Eye Clinic. There was a statistically significant association to systemic disorders such as hypertension and DM and majority of cases with 6th cranial nerve palsy. PMID:24791110

    The transition of patients from failing dentition to complete-arch implant rehabilitation often means that the patient is rendered edentulous and has to wear a removable complete denture for a time. Many patients find this objectionable. A staged treatment approach provides a fixed interim prosthesis for use throughout the rehabilitation process, allowing patient comfort and prosthodontic control. This clinical report describes a staged approach protocol with a new type of interim prosthesis. The prosthesis is supported by hopeless teeth and the soft tissues of the maxillary tuberosities and mandibular retromolar pads for the complete-arch implant rehabilitation of a patient with failing dentition. This protocol allows for a fixed interim prosthesis with combined tooth and mucosa or implant support during the entire rehabilitation process, thus avoiding the use of complete dentures. The implants and prostheses were functioning successfully after 3 years of clinical service. Copyright © 2014 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

    To compare the 3-year stability, survival, and tolerability of 2 osseointegrated implants for bone conduction hearing: a wide 4.5-mm-diameter moderately roughened implant with a rounded 6-mm abutment (test) and a 3.75-mm diameter as-machined implant with a conically shaped 5.5-mm abutment (control). In this randomized, prospective, controlled, multicenter clinical study, 77 adult patients were included. Test and control implants were randomly assigned in proportions of 2:1. The implants were loaded with the sound processor from 6 weeks postimplantation. Follow-up after surgery was conducted at 10 days; at 4, 6, 8, and 12 weeks; and at 6, 12, 24, and 36 months after surgery. At every visit, implant stability quotient (ISQ) values were recorded by means of resonance frequency analysis (RFA), and skin reactions were evaluated according to Holgers' classification. Statistically significantly higher mean ISQ values were recorded for the test implant compared with the control implant at each evaluation time point. Between 2 and 3 years after surgery, ISQ values decreased but remained above baseline values. Implant survival was high for both implants: 96.2% of the test implants and 100% of the control implants survived these 3 years. Statistically significantly improved soft tissue outcomes were observed in the test implant group. This extensive long-term clinical investigation demonstrated that the test implant is more stable in terms of ISQ-values and provides high tolerability for the soft tissue. The results show that implant loading at 6 weeks is safe.

    The aim of this study was to evaluate the 3-year success rates of wide-body implants with a regular- or wide-neck configuration and a sandblasted, large grit, acid-etched (SLA) surface. A total of 151 implants were consecutively placed in posterior sites of 116 partially edentulous patients in a referral clinic at the School of Dental Medicine, University of Bern. All implants were restored with cemented crowns or fixed partial dentures after a healing period of 6 to 8 weeks (for implants placed without simultaneous bone augmentation) or 10 to 14 weeks (for implants with simultaneous bone augmentation). All patients were recalled 36 months following implant placement for a clinical and radiographic examination. One implant failed to integrate during healing, and 11 implants were lost to follow-up and considered dropouts. The remaining 139 implants showed favorable clinical and radiographic findings and were considered successfully integrated at the 3-year examination. This resulted in a 3-year success rate of 99.3%. Radiographic evaluation of 134 implants indicated stability of the crestal bone levels: During the study period, the crestal bone level changed less than 0.5 mm for 129 implants. Successful tissue integration was achieved with wide-body implants with a regular or a wide-neck configuration and an SLA surface with high predictability. This successful tissue integration was well maintained for up to 3 years of follow-up.

    Because of the clinical difficulty in identifying the early stages of human immunodeficiency virus (HIV) infection, the histopathologist often has to consider the diagnosis of HIV in tissue samples from patients with no previous suspicion of HIV infection. The aim was to investigate the practicality and utility of routine HIV-1 p24 immunohistochemistry on tissue samples received at a London histopathology laboratory. Over a 3-year period, HIV-1 p24 was evaluated immunohistochemically on 123 cases. Of these, 37 (30%) showed positive expression of p24 in lesional follicular dendritic cells (FDCs). Of these 37 cases, 11 were not clinically suspected to be HIV+ and had no prior serological evidence of HIV infection. These cases represented lymph node biopsies, tonsillar and nasopharyngeal biopsies and a parotid excision. In addition to expression on FDCs, in 22 cases (60%), p24 also highlighted mononuclear cells and macrophages. p24 was also useful in confirming the presence of HIV in lymphoid tissue in non-lymphoid organs such as the lung, anus, salivary gland and brain. Immunonegativity occurred in occasional known HIV+ cases, probably related to treatment or tissue processing. This study confirms the usefulness of this technique in detecting unsuspected HIV infection in lymphoid and non-lymphoid organs on histopathological material and should be part of routine evaluation of lymph nodes and lymphoid tissue in other organs if morphological or clinical features suggest HIV infection.

    The long-term stability of posterior crossbite correction in the mixed dentition has not been sufficiently evaluated. Our aim was to compare long-term outcomes in patients with crossbite correction by using matched controls with normal occlusion. After 35 patients were treated for crossbite with a quad-helix or an expansion plate, we used randomized controlled trial methodology to follow them for 3 years posttreatment. All had fulfilled our pretreatment criteria: mixed dentition, unilateral posterior crossbite, no sucking habits, and no previous orthodontic treatment. Transverse relationships, maxillary and mandibular widths, overbite, overjet, arch lengths, and midlines were registered on the study models immediately before and after treatment and at the follow-up 3 years after treatment. The matched control group comprised 20 subjects with normal occlusion and was compared with the first and last registrations for the treated groups. At follow-up, changes in the treatment groups were equal and stable. The changes were comparable with the control group. All other changes were minor and had no clinical implications. The long-term effect of crossbite correction on midline deviation was unpredictable. If crossbite is successfully corrected by the quad-helix appliance or the expansion plate, similar long-term stability is achieved. However, in treated patients, mean maxillary widths never reached those of normal control subjects. Copyright © 2011 American Association of Orthodontists. Published by Mosby, Inc.

    Background Chronic obstructive pulmonary disease is a major inflammatory disease of the airways and an enormous therapeutic challenge. Within the spectrum of chronic obstructive pulmonary disease, pulmonary emphysema is characterized by the destruction of the alveolar walls with an increase in the air spaces distal to the terminal bronchioles but without significant pulmonary fibrosis. Therapeutic options are limited and palliative since they are unable to promote morphological and functional regeneration of the alveolar tissue. In this context, new therapeutic approaches, such as cell therapy with adult stem cells, are being evaluated. Objective This article aims to describe the follow-up of up to 3 years after the beginning of a phase I clinical trial and discuss the spirometry parameters achieved by patients with advanced pulmonary emphysema treated with bone marrow mononuclear cells. Methods Four patients with advanced pulmonary emphysema were submitted to autologous infusion of bone marrow mononuclear cells. Follow-ups were performed by spirometry up to 3 years after the procedure. Results The results showed that autologous cell therapy in patients having chronic obstructive pulmonary disease is a safe procedure and free of adverse effects. There was an improvement in laboratory parameters (spirometry) and a slowing down in the process of pathological degeneration. Also, patients reported improvements in the clinical condition and quality of life. Conclusions Despite being in the initial stage and in spite of the small sample, the results of the clinical protocol of cell therapy in advanced pulmonary emphysema as proposed in this study, open new therapeutic perspectives in chronic obstructive pulmonary disease. It is worth emphasizing that this study corresponds to the first study in the literature that reports a change in the natural history of pulmonary emphysema after the use of cell therapy with a pool of bone marrow mononuclear cells.

    The aim of this randomized, controlled, prospective clinical study was to compare guided tissue regeneration (GTR) to enamel matrix derivative (EMD) for the treatment of intrabony defects in patients with chronic advanced periodontitis. Forty (39 evaluable) 3-wall intrabony defects, each with a depth > or = 4 mm measured from the crest of the bony defect, were treated in 40 subjects with advanced chronic periodontitis. Regeneration of angular bone defects was induced using non-resorbable membranes (GTR group; n = 20) or EMD (EMD group; evaluable n = 19). Clinical parameters, including probing depth (PD), clinical attachment level (CAL), gingival recession, radiographic measurement of the defect depth, plaque index, and bleeding on probing, were measured at baseline and at 12 and 36 months following surgery. Twelve months after surgery, sites treated with GTR demonstrated a mean CAL gain of 2.5 +/- 1.2 mm and a mean reduction in PD of 3.5 +/- 1.2 mm compared to baseline. The corresponding outcomes at 36 months were 2.0 +/- 1.1 mm (CAL) and 3.2 +/- 1.1 mm (PD). Sites treated with EMD demonstrated a mean CAL gain of 2.9 +/- 1.4 mm and a mean reduction in PD of 3.5 +/- 1.4 mm at 12 months, with a mean CAL gain of 2.4 +/- 1.2 mm and a mean PD reduction of 3.1 +/- 1.4 mm at 36 months. The differences in PD reduction and CAL gain were statistically significant between the groups and for each time point compared to baseline. Attachment loss was seen in both groups between the 12- and 36-month observations. Measured radiographic bone fill was 57.0% +/- 21% at 12 months and 53.7% +/- 14.3% at 36 months in the GTR group compared to 50.5% +/- 19% at 12 months and 58.8% +/- 14.9% at 36 months in the EMD group. The treatment of intrabony defects in patients with chronic advanced periodontitis using GTR or EMD led to significantly improved clinical parameters. Tests of statistical significance demonstrated better results with EMD, although the absolute differences between

    Pneumococcal capsular polysaccharide vaccine is a mainstay for prevention of Streptococcus pneumoniae infection in adults. There is the possibility that this vaccine is less effective in patients undergoing immunosuppressive therapy. In the present study, we aimed to evaluate the immune response following 23-valent pneumococcal polysaccharide vaccination in pulmonary disease patients receiving steroids and immunosuppressive agents (immunosuppressive group). Antibody levels were measured over 3 years in the immunosuppressive group (median age: 68.5 years) and in aged-match pulmonary disease patients not being treated with immunosuppressive therapy (control group) using enzyme-linked immunosorbent assays. The geometric mean antibody levels were significantly increased after vaccination in both groups (p < 0.05) and remained above baseline for 3 years. The fold increases 1 month after vaccination were 9.4 (95% confidence interval [CI]: 5.7-15.6) and 8.8 (95% CI: 5.8-13.2) in the immunosuppressive and control groups, respectively (p = 0.813). There was no significant difference in the proportion of subjects with a ≥ two-fold increase of antibody level between the immunosuppressive and control groups at any point. These results suggest that immunization with the 23-valent pneumococcal polysaccharide vaccine was effective, even in patients undergoing immunosuppressive therapy and should be recommended for such patients.

    The aim of the present pilot study was to test whether or not posterior zirconia-ceramic fixed dental prostheses (FDPs) with pressed veneering ceramic exhibit less chipping than FDPs with layered veneering ceramics. Forty patients (13 female, 27 male; mean age 54 years (range 26.1-80.7 years) in need of one maxillary or mandibular three-unit FDP in the second premolar or molar region were recruited and treated at two separate centers at the University of Zurich according to the same study protocol. The frameworks were made out of zirconia using a CAD/CAM system (Cerec Sirona, Bensheim, Germany). The patients were randomly assigned to either the test group (zirconia frameworks veneered with pressed ceramic; IPS e.max ZirPress, Ivoclar Vivadent AG, Schaan, Liechtenstein; n=20) or the control group (layered veneering ceramic; IPS e.max Ceram, Ivoclar Vivadent AG, Schaan, Liechtenstein; n=20). All FDPs were adhesively cemented and evaluated at baseline (i.e., cementation), at 6 months and at 1 and 3 years of clinical service. The survival of the reconstruction was recorded. The technical outcome was assessed using modified United States Public Health Services (USPHS) criteria. The biologic parameters analyzed at abutment teeth and analogous non-restored teeth included probing pocket depth (PPD), plaque control record (PCR), bleeding on probing (BOP), and tooth vitality (CO2). Data was descriptively analyzed and survival was calculated using Kaplan-Meier statistics. 36 patients (25 female, 11 male; mean age 52.3 years) with 18 test and 18 control FDPs were examined after a mean follow-up of 36 months (95% CI: 32.6-39.1 months). Comparison of groups was done by Crosstabulation showing even distribution of the respective restored teeth amidst the groups. Survival rate was 100% for both test and control FDPs. Chipping of the veneering ceramic tended to occur more frequently in test (n=8; 40%) than in control (n=4; 20%) FDPs, albeit not significantly (p=0.3). No further

    Freeze-dried bone allograft is an interesting treatment alternative to autogenous bone grafts. This clinical report presents a 3-year follow-up of an atrophic maxilla treated with freeze-dried bone allograft. Ridge augmentation was conducted with freeze-dried tibial allografts. Eight implants were used to support a full-arch prosthesis. Three years later, clinical and radiographic follow-up showed bone surrounding the dental implants. Histologic sections showed the presence of biologically active bone. This clinical case supports the use of freeze-dried allograft as an alternative for the reconstruction of the atrophic maxilla.

Among 1505 K. pneumoniae, 7 were pAmpC producers. Molecular characterization revealed the spread of a ST37 strain producing DHA-1 within intensive care units and the diffusion of the same plasmid among unrelated strains.

    Real-world functional deficits are common and persistent in individuals with psychosis. Cognitive deficits have been shown to compromise functioning. We aimed to study the predictive values of premorbid, sociodemographic, and baseline clinical and neurocognitive factors on long-term functional outcome for individuals with first episode non-affective psychosis. We failed to demonstrate a significant relationship between cognitive deficits at baseline and functional disability at 3 year follow-up. Diagnosis of schizophrenia (OR=2.457, p=0.011), shorter education (OR=1.177, p=0.005) and poor premorbid social adjustment (OR=1.628, p=0.013) emerged as the strongest predictors for the 114 subjects (56%) that exhibited functional disability at 3-year follow-up. A considerable proportion of the variance in functioning (74% at 1 year and 77% at 3 year) remained unexplained by baseline variables. The set of variables that predicted functional outcome at medium- (1 year) and long-term (3 years) differed. In conclusion, the length of follow-up influenced the relationship between baseline variables and functional outcome. A substantial proportion of the variance in function was not explained by these variables and therefore the influence of other factors warrants further investigation. The data support the notion that premorbid social adjustment is an important aspect in functional outcome over the course of the illness. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    This randomized parallel-group clinical pilot study aimed to compare the clinical outcome of prefabricated rigid titanium to glass fiber endodontic posts when luted with self-adhesive universal resin cement. Ninety-eight patients in need of postendodontic restoration were assessed for eligibility. Ninety-one patients met the selection criteria and were randomized and allocated to 2 intervention groups. Forty-five participants were treated using a titanium post and 46 participants received a glass fiber post, each in combination with composite core buildups for postendodontic restoration. All posts had a diameter of 1.4 mm and a length of 13 mm and were cemented 8 mm within the root canal with self-adhesive universal resin cement. A circumferential ferrule of 2 mm was always provided. Surgical crown lengthening was necessary in 13 cases. Patients were observed in intervals of 3, 6, 12, 24, and 36 months after post placement. After 24 to 36 months (mean +/- SD: 27.9 +/- 5.6) of observation following post placement, 1 tooth was extracted because of changes of the prosthetic treatment plan. No failures were observed among the 88 patients with follow-up data. Both titanium and glass fiber reinforced composite posts result in successful treatment outcomes after 2 years. The material combination used seems to be appropriate in the short term for cementing endodontic posts, irrespective of the post material.

    The main aim of the study was to compare the clinical performance of the conventional high-powder/liquid ratio glass-ionomer cement (GIC) Fuji IX GP Extra (F IX), Fuji IX GP Extra with a low-viscosity nano-filled resin coating, G-Coat Plus (F IX+GCP), and a resin composite, Solare (S), as a comparison material. Moderate-depth occlusal cavities in the first permanent molars of 91 11-12-year-old children (1-4 restorations per child) were restored with either F IX (87 restorations), F IX+GCP (84 restorations) or S (83 restorations). Direct clinical assessment, photographic assessment and assessment of stone casts of the restorations were carried out at 6 months, 1 year, 2 years and 3 years. The colour match with the tooth of the GIC restorations improved over the 3 years of the study. Marginal staining and marginal adaptation were minimal for all restorations; three restorations exhibited secondary caries at 3 years. From the assessment of the casts, at 2 years, there was significantly less wear of the F IX GP Extra+GCP restorations than the F IX GP Extra restorations (P < 0.005). At 3 years, approximately 37 % of F IX GP Extra restorations showed wear slightly more than the adjacent enamel, compared to 28 % of F IX GP Extra+GCP restorations and 21 % of Solare restorations. Although this was not statistically significant, there was a trend that GCP can protect F IX GP Extra against wear. Although both Fuji IX GP Extra and Fuji IX GP Extra with G-Coat Plus showed acceptable clinical performance in occlusal cavities in children, the application of G-Coat Plus gave some protection against wear. The application of G-Coat Plus to Fuji IX GP Extra glass-ionomer cement may be beneficial in reducing wear in occlusal cavities.

    To study the risk factors, microbiological profile and clinical outcomes of infectious keratitis affecting paediatric patients. Retrospective case series. Review of case records of paediatric patients (0-16 years) diagnosed with infectious keratitis who presented to Aravind Eye Hospital, Madurai, India during January 2011 to December 2013. Demographic details, predisposing factors, microbiological investigations, clinical course and visual outcome were analysed. In this time period, 240 eyes of 234 children had a diagnosis of infectious keratitis. One hundred and twenty-five (53.4%) children had a history of trauma. Smears were obtained in 220 eyes, while culture was performed in 191 eyes. The culture results were positive in 142 (74.3%) eyes. Fungi was the most common infectious agent isolated in culture (54.2%) followed by bacteria (40.8%) and acanthamoeba (2.1%). Successful healing of the keratitis with appropriate medical therapy occurred in 223 (92.9%) eyes, while 17 (7.1%) eyes required therapeutic keratoplasty. Of the 151 patients with preliminary and final visual acuity, vision improved by 2 lines in 68 eyes (45%), stayed the same in 75 eyes (49.6%) and worsened in 8 eyes (5.3%). Contrary to previous reports, fungi are the most common aetiological organism in the causation of infectious keratitis in children in our study population. Fusarium was the most common fungal species isolated. These data are similar to the data obtained from adult patients with infectious keratitis in this region. While microbiological investigations are important to initiate appropriate antimicrobial therapy, the findings from our study need to be kept in mind, especially while initiating empirical therapy in this population.

    To evaluate marginal bone loss over 3 years around immediate microthreaded implants placed in the maxillary anterior/esthetic zone and immediately restored with single crowns. Seventy-one implants (with microthreads up to the platform--rough surface body and neck, internal connection and platform switching) were placed in fresh extraction sockets in the maxillary arches of 30 men and 23 women (mean age 37.85 ± 7.09 years, range 27-60). All subjects had at least 3 mm of soft tissue to allow the establishment of adequate biologic width and to reduce bone resorption. Each patient received a provisional restoration immediately after implant placement with slight occlusal contact. Mesial and distal bone height was evaluated using digital radiography on the day following implant placement (baseline) and after 1, 2, and 3 years. Primary stability was measured with resonance frequency analysis. No implants failed, resulting in a cumulative survival rate of 100% after 3 years. Marginal bone loss from implant collar to bone crest measured at baseline (peri-implant bone defect at the fresh extraction socket) and after 3 years was 0.86 mm ± 0.29 mm. Mesial and distal site crestal bone loss ranged from 3.42 mm ± 1.2 mm at baseline to 3.51 mm ± 1.5 mm after 3 years (P = 0.063) and from 3.38 mm ± 0.9 mm at baseline to 3.49 mm ± 0.9 mm after 3 years, respectively (P = 0.086). This prospective study found minimal marginal bone loss and a 100% implant survival rate over the 3-year follow-up for microthreaded immediate implants subjected to immediate non-occlusal loading. © 2014 John Wiley & Sons A/S.

    A comparison of the Q3 and Hybrid III 3-year-old crash test dummies is presented in this paper. The performance of the dummies were compared in sixty biofidelity tests, seventy-seven static out-of-position airbag tests and sixty-three calibration tests. Various time histories and other data pertaining to accelerations, deflections, forces and moments are compared. In addition, the ease of positioning, handling, and the durability of the dummies in various out-of-position test configurations was assessed. Both the Q3 and Hybrid III 3-year-old dummies were calibrated to their respective specifications. The Hybrid III 3-year-old met its calibration requirements, while the Q3 did not always meet its own calibration requirements. The calibration specifications of the Q3 dummy need to be re-examined and possibly refined. The biofidelity of the Q3 and Hybrid III 3-year-old dummies were evaluated in both frontal and lateral test modes. Each dummy was evaluated against its own and the other's specified requirements, when possible. In the frontal test mode, the Hybrid III 3-year-old acceptably met all of its requirements. The Q3 dummy did not meet all of its own frontal biofidelity requirements. Based on these results, the Hybrid III 3-year-old is more biofidelic for primarily frontal loading conditions. With respect to the lateral biofidelity specifications, neither the Hybrid III 3-year-old nor the Q3 dummy met the requirements for the thorax and pelvis tests performed. Both dummies met the head drop requirements. Neither dummy is recommended for lateral loading conditions. For lateral testing where only the head is impacted, the Hybrid III 3-year-old could be used. In general, the responses of both dummies were repeatable in both the frontal and lateral biofidelity tests performed. The Hybrid III 3-year-old and the Q3 dummies were evaluated in static out-of-position airbag tests with three different side airbag systems (two seat-mounted and one door-mounted system), and

    Factor XI (FXI)-deficient patients may develop excessive bleeding after trauma or surgery. Replacement therapy should be considered in high-risk situations, especially when FXI levels are below 20 IU dL(-1) . HEMOLEVEN is a human plasma-derived factor XI concentrate available in France since 1992, but there are few data regarding its use by physicians. This prospective study assessed the use, efficacy and safety of HEMOLEVEN in common clinical practice. HEMOLEVEN was evaluated in FXI-deficient patients in 13 French centres in a 3-year postmarketing study. Forty-four patients (30 females, 14 males) received 67 treatments. The median age was 37 years (8 months-91 years). Basal FXI levels were <1 to 51 IU dL(-1) (median: 5.5); 29 patients were severely FXI-deficient (<20 IU dL(-1) ). FXI was administered prophylactically before 43 surgical procedures, 10 invasive procedures, 8 vaginal deliveries, or as curative treatment for six bleeds. The efficacy was assessed as excellent/good in 63, moderate in two and undetermined in two treatments. Seven patients experienced seven adverse effects, including two rated as serious: one sudden massive pulmonary embolism with fatal outcome and one case of inhibitor to FXI. HEMOLEVEN is effective for bleeding prevention in FXI deficiency. However, considering the benefit/risk ratio observed in relation to dosage in this study; firstly, it should be used sparingly due to its potential prothrombotic effect; secondly, new prescription procedures should be defined to adapt the dosage, especially in patients with intrinsic and/or acquired risk factors for thrombosis. © 2015 John Wiley & Sons Ltd.

    The prevalence of osteoporosis in the Netherlands is 52 per 1,000 men and 166 per 1,000 women (age >55 years). Previous results of an osteoporosis screening program showed that 55%, 41%, and 37.1% had osteoporosis. This study aims to evaluate the incidence of osteoporosis after low-energy fractures and to describe the care program for osteoporosis screening. The second endpoint was to investigate the incidence of risk factors in the whole study population and a subgroup analysis from the three major groups with osteoporotic fractures. All female and male patients older than 50 years with a low-energy fracture were included for the osteoporosis screening program. Patients with a fracture of the vertebrae were also included if the age was less than 50 years. All patients underwent a bone mineral density measurement by means of dual-energy X-ray film absorptiometry. All obtained data were registered by a nurse specialist in osteoporosis, in a computerized database. The incidence of osteoporosis in patients with low-energy fractures is high, 46.4%. At the time of fracture presentation, there were 33.2% of the patients with a low body weight (<67 kg), almost all osteoporotic patients (96%) had a low-energy fracture occurred after their 50th year. In patients diagnosed with osteoporosis, the hip fracture is the most common fracture site (34%), followed by the humerus (20.1%). In conclusion, a screening program for osteoporosis is necessary and should be a tool in the armamentarium of every traumatology department.

    Background The short- and mid-term outcomes of the second-generation cobalt-chromium sirolimus-eluting stent (CoCr-SES) in real-world patients had been reported previously, but the long-term performance remained unclear. The objective of this analysis was to evaluate the long-term safety and efficacy of the second-generation CoCr-SES from the FOCUS registry. Methods The FOCUS registry (ClinicalTrials.gov Identifier: NCT00868829) enrolled all-comers eligible to receive Firebird-2 CoCr-SES. Follow-up was continued to 3 years to evaluate long-term safety and effectiveness of the second-generation CoCr-SES in real-world practice. Results of the extended-use group and standard-use group are compared to explore performance of CoCr-SES in more severe patients with more complex lesions. Results The rate of 3-year MACE was 7.37%, consisting of 84 cases (1.78%) of cardiac death, 166 cases (3.52%) of MI and 98 cases (2.08%) of TVR. ARC definite/probable stent thrombosis happened in 34 (0.72%) patients, only 3 new cases (<0.1%) of very late stent thrombosis was reported in the third year. Meanwhile, the difference of MACE (7.77% vs. 6.06%; P=0.058), TLF (4.71% vs. 3.49%; P=0.085) and ARC definite/probable stent thrombosis (0.83% vs. 0.37%; P=0.116) between extended-use group and standard-use group showed no significance. Conclusions The second-generation CoCr-SES was associated with continued low rates of 3-year MACE, TLF and stent thrombosis in a broad spectrum of patients. PMID:27499948

    In this controlled clinical trial, initial and long-term treatment outcomes of guided tissue regeneration (GTR) were investigated for a synthetic absorbable membrane (Atrisorb) in intrabony defects. Eighteen defects in 16 patients received GTR with Atrisorb (test), with the membrane applied by an indirect method, and 15 defects in 15 patients were treated with open flap debridement (control). Probing pocket depth (PPD), gingival recession (GR), clinical attachment level (CAL), and linear alveolar bone level (ABL) were recorded at baseline and at 1 and 3 years following the treatment procedures and were assessed as the therapeutic outcome parameters. Both groups demonstrated significant PPD reduction and CAL and ABL gain after 1 year. Among these parameters, alterations in PPD and CAL were statistically significantly greater in the test group than the control group 1 year postsurgery. No significant changes were noted in the parameters of the first year between and within the study groups after 3 years. The results suggest that GTR performed with Atrisorb membrane via an indirect application method may provide favorable clinical outcomes for intrabony defects, and these outcomes may be maintained at least as well as open flap debridement over an extended period.

    The clinical evaluation of patients with tinnitus differs based on whether the tinnitus is subjective or objective. Subjective tinnitus is usually associated with a hearing loss, and therefore, the clinical evaluation is focused on an otologic and audiologic evaluation with adjunct imaging/tests as necessary. Objective tinnitus is divided into perception of an abnormal somatosound or abnormal perception of a normal somatosound. The distinction between these categories is usually possible based on a history, physical examination, and audiogram, leading to directed imaging to identify the underlying abnormality.

    Autoantibodies in early rheumatoid arthritis (RA) have important diagnostic value. The association between the presence of autoantibodies against cyclic citrullinated peptide and the response to treatment is controversial. To prospectively evaluate a cohort of patients with early rheumatoid arthritis (<12 months of symptoms) in order to determine the association between serological markers (rheumatoid factor (RF), anti-citrullinated protein antibodies) such as anti-cyclic citrullinated peptide antibodies (anti-CCP) and citrullinated anti-vimentin (anti-Sa) with the occurrence of clinical remission, forty patients diagnosed with early RA at the time of diagnosis were evaluated and followed for 3 years, in use of standardized therapeutic treatment. Demographic and clinical data were recorded, disease activity score 28 (DAS 28), as well as serology tests (ELISA) for RF (IgM, IgG, and IgA), anti-CCP (CCP2, CCP3, and CCP3.1) and anti-Sa in the initial evaluation and at 3, 6, 12, 18, 24, and 36 months of follow-up. The outcome evaluated was the percentage of patients with clinical remission, which was defined by DAS 28 lower than 2.6. Comparisons were made through the Student t test, mixed-effects regression analysis, and analysis of variance (significance level of 5%). The mean age was 45 years, and a female predominance was observed (90%). At the time of diagnosis, RF was observed in 50% of cases (RF IgA-42%, RF IgG-30%, and RF IgM-50%), anti-CCP in 50% (no difference between CCP2, CCP3, and CCP3.1) and anti-Sa in 10%. After 3 years, no change in the RF prevalence and anti-CCP was observed, but the anti-Sa increased to 17.5% (P = 0.001). The percentage of patients in remission, low, moderate, and intense disease activity, according to the DAS 28, was of 0, 0, 7.5, and 92.5% (initial evaluation) and 22.5, 7.5, 32.5, and 37.5% (after 3 years). There were no associations of the presence of autoantibodies in baseline evaluation and in serial analysis with the percentage of

    We sought to compare the long-term safety of two devices with different antiproliferative properties: the Endeavor zotarolimus-eluting stent (E-ZES; Medtronic, Inc) and the Cypher sirolimus-eluting stent (C-SES; Cordis, Johnson & Johnson) in a broad group of patients and lesions. Between May 21, 2007 and Dec 22, 2008, we recruited 8791 patients from 36 recruiting countries to participate in this open-label, multicentre, randomised, superiority trial. Eligible patients were those aged 18 years or older undergoing elective, unplanned, or emergency procedures in native coronary arteries. Patients were randomly assigned to either receive E-ZES and C-SES (ratio 1:1). Randomisation was stratified per centre with varying block sizes of four, six, or eight patients, and concealed with a central telephone-based or web-based allocation service. The primary outcome was definite or probable stent thrombosis at 3 years and was analysed by intention to treat. Patients and investigators were aware of treatment assignment. This trial is registered with ClinicalTrials.gov, number NCT00476957. PROTECT randomised 8791 patients, of whom 8709 provided consent to participate and were eligible: 4357 were allocated to the E-ZES group and 4352 patients to the C-SES group. At 3 years, rates of definite or probable stent thrombosis did not differ between groups (1·4% for E-ZES [predicted: 1·5%] vs 1·8% [predicted: 2·5%] for C-SES; hazard ratio [HR] 0·81, 95% CI 0·58-1·14, p=0·22). Dual antiplatelet therapy was used in 8402 (96%) patients at discharge, 7456 (88%) at 1 year, 3041 (37%) at 2 years, and 2364 (30%) at 3 years. No evidence of superiority of E-ZES compared with C-SES in definite or probable stent thrombosis rates was noted at 3 years. Time analysis suggests a difference in definite or probable stent thrombosis between groups is emerging over time, and a longer follow-up is therefore needed given the clinical relevance of stent thrombosis.

    The transition of patients from failing dentition to complete arch implant rehabilitation often requires that the patient be rendered edentulous and has to wear a complete removable dental prosthesis for varying periods of time. This is objectionable to many patients. A staged treatment approach allows a fixed interim restoration, patient comfort, and prosthodontic control throughout the rehabilitation process. CAD/CAM-guided flapless implant surgery has the advantage of prosthetically driven implant placement and minimal postoperative sequelae. A patient with a failing dentition was treated with this combined protocol and was followed up for 3 years after loading. Implant and prosthesis survival rates were 100%, with no technical complications encountered up to the last recall. The purpose of this clinical report is to describe a combination of CAD/CAM-guided flapless surgery and a staged treatment approach, thereby giving the patient a tooth-supported or implant-supported fixed interim prosthesis during the entire rehabilitation process. The various surgical, laboratory, and prosthetic stages are illustrated for the complete arch prosthetic rehabilitation, and the 3-year follow-up outcome is reported.

    Diabetic burns patients may be at risk of worse clinical outcomes. This study aims to further investigate the impact of diabetes mellitus on clinical outcomes in burns patients in Singapore. A 3-year retrospective review was performed at the Singapore General Hospital Burns Centre (2011-2013). Pure inhalational burns were excluded. Diabetic (N=53) and non-diabetic (N=533) patients were compared, and the impact of diabetes on clinical outcomes, adjusting for confounders, was investigated using multivariate logistic regression. The diabetic group had a significantly higher incidence of wound infection and severe renal impairment, as well as a longer length of stay, higher number of operations and higher rate of unplanned readmission. ICU admission was significantly associated with hyperglycaemia (OR 5.44 [2.61-11.35], p<0.001) and a higher total body surface area of burn (OR per 1% TBSA 1.07 [1.05-1.09], p<0.001). Unplanned readmission was significantly associated with wound infection (OR 4.29 [1.70-10.83], p=0.002), and mortality associated with a higher TBSA (OR per 1% TBSA 1.1 [1.07-1.14], p<0.001). After adjusting for confounders, diabetes mellitus was not significantly associated with unplanned readmission or mortality. Diabetic burns patients have an increased risk of worse clinical outcomes, including wound infections, renal impairment and longer length of stay. Copyright © 2016 Elsevier Ltd and ISBI.

    To evaluate non-chemical strategies to control pasture-borne parasites in first-season grazing (FSG) cattle, a 3-year grazing trial was conducted during 2002-2004 on naturally infected pastures on a commercial beef cattle farm in Sweden. A uniform pasture was divided in 4 equal 2 ha paddocks onto each of which 10, 5-9 months old dairy breed steer calves were allocated at turn-out in May each year. Two strategies were evaluated: (1) turn-out onto pasture which had been grazed the previous year by second-season grazing (SSG) steers, followed by a move to aftermath in mid-July (RT) and (2) supplementation with concentrate and roughage for 4 weeks from turn-out (FD). Comparisons were made with an untreated (UT), and an anthelmintic treated control group (DO). Animal parasitology and performance were monitored monthly throughout the 20 weeks grazing period. Additional sampling occasions were performed on day 9 (for coccidia) and 10 weeks after turn-out (mid-July). Due to clinical parasitic gastro-enteritis (PGE), salvage treatments were performed on all animals in group FD approximately 7 weeks after turn-out in 2003 and of three animals in group UT 5 weeks after turn-out in 2004. In 2003, the geometric mean oocyst excretion 9 days after turn-out was approximately 150,000 opg of mainly Eimeria alabamensis in group FD, and in 2004 approximately 180,000 opg in group UT. Apart from the DO group, geometric mean faecal egg counts (FEC) were between 80 and 400 epg 4 weeks after turn-out. Mean serum pepsinogen concentrations (SPC) of approximately 3.6 U tyrosine were recorded in the FD and UT groups from late August 2002. In 2003 and 2004, mean concentrations in these groups were between 4.1 and 7.2 U tyrosine 8 weeks after turn-out. By the end of the three grazing seasons the average weight gain difference compared to the DO group was for FD -29, -38 and -5 kg and for RT -4, -21 and +14 kg, and compared to the UT group -18, +2 and +22 for FD and +7, +19 and +41 kg for group

Differences among male and female patients emerged in effectiveness and safety of therapeutics in some diseases. Especially in dyslipidemia, ischemic heart diseases and heart failure, trials in which women are better represented and guidelines that evaluate findings in women more detailed are needed. This article evaluates differences among men and women in some landmark trials that are used among main references in management guidelines.

    We report a 3-year-old Peruvian girl, born to non-consanguineous parents. At the age of 8 months, she had a severe pneumonia complicated with empyema that required thoracic drainage and mechanical ventilation. Although no microorganisms were isolated, the patient recovered with broad-spectrum antibiotics. Since that date, she has presented multiple episodes of pneumonia and recurrent episodes of bronchospasm. At 1 year 5 months of age, the patient began with recurrent episodes of oropharyngeal, vaginal, and skin candidiasis, which improved transiently after using oral azole drugs. At 2.5 years of age, she was admitted with lupus-like syndrome, including serositis, hemolytic anemia, thrombocytopenia, and positive antinuclear (1:80) and dsDNA (1:10) autoantibodies. Available immunologic testing was not contributory. Imaging studies revealed bilateral ethmoidal sinusitis and mild hepatomegaly. Bone marrow analysis did not showed evidence of leukemia or myelodysplasia, while renal biopsy concluded mild mesangial proliferation. Genetic studies revealed a pathogenic heterozygous signal transducer and activator of transcription 1 gain-of-function mutation (WT/P293L). The clinical status and lung function of the patient has worsened progressively. She has not achieved an optimal response to therapy, including high-dose intravenous immunoglobulin, GM-CSF, prophylactic antibiotics and antifungal drugs, so we plan to perform hematopoietic stem cell transplantation.

    To determine, in a 3-year clinical trial, whether tooth type and ferrule significantly affect the survival of pulpless teeth restored with fiber posts. A sample of 87 teeth in 87 patients (32 men and 55 women, age ranged from 23 to 78) were restored using Snowpost: 34 incisors, 12 canines, 25 premolars and 16 molars. The posts were cemented with RelyXUnicem and the core was made with a resin composite (Dentocore Automix). Every tooth was covered with a metal-ceramic or all ceramic crown. Two experimental groups, according to the presence or absence of ferrule, were defined: A) 45 teeth with ferrule (>2 mm height); and B) 42 teeth without ferrule (<2 mm height). Patients were reevaluated every 6 months. 14 of the total restorations failed (16.1%). The failure modes were caries (n=4), post fracture (n=4), root fracture (n=2), and marginal gap, post cement failure, crown cement failure, and periapical lesion (n= 1 respectively). In Group A the failure observed was 6.67% and in Group B it was 26.20%. The log-rank test showed statistically significant differences between both groups. According to the type of tooth, the incisors were the teeth with the highest failure rate (73.52%), but Chi-square test showed no statistically significant differences among the four tooth types, perhaps because of the low number of the sample.

    Meningeal tumors are extremely rare in children and are diagnostically as well as therapeutically challenging. Among the least common types of malignancies in childhood is malignant melanoma, counting for less than 1% of pediatric tumors. Due to the rarity and the wide spectrum of appearance, initial clinical features may be misleading. A 3-year-old boy was referred to our hospital with symptoms of hyperventilation, dyspnoea, tachycardia, respiratory alkalosis, inarticulate speech, and fatigue. Measurement of pH in cerebrospinal fluid (CSF) yielded central lactic acidosis despite alkalosis in peripheral blood. Diagnostic imaging procedures as well as histology and immunohistochemistry revealed the diagnosis of a malignant meningeal melanoma. We hypothesize that central lactate production of the tumor nests might have induced central acidification, thus inducing hyperventilation by stimulation of central chemoreceptors. This case is a model example of the key role of central pH as an inducer/suppressor of ventilation in humans and illustrates the critical importance of central pH for regulating both ventilation and acid-base homeostasis. Thus, pH of CSF should be measured whenever a malignant brain tumor is suspected.

    The occurrence of decompensation marks a crucial turning point in the course of cirrhosis. The purpose of this study was to assess the risk of mortality according to the clinical characteristics of first decompensation, considering also the impact of acute-on-chronic liver failure (AoCLF). We conducted a prospective nationwide inception cohort study in Italy. Decompensation was defined by the presence of ascites, either overt or detected by ultrasonography (UD), gastroesophageal variceal bleeding (GEVB), and hepatic encephalopathy (HE). AoCLF was defined according to the Asian Pacific Association for the Study of the Liver criteria. Multivariable Cox proportional hazards regression was used to analyze the risk of failure (death or orthotopic liver transplantation (OLT)). A total of 490 consecutive cirrhotic patients (314 males, mean age 60.9±12.6 years) fulfilled the study criteria. AoCLF was identified in 59 patients (12.0%). Among the remaining 431 patients, ascites were found in 330 patients (76.6%): in 257 (77.8%) as overt ascites and in 73 (22.2%) as UD ascites. GEVB was observed in 77 patients (17.9%) and HE in 30 patients (7.0%). After a median follow-up of 33 months, 24 patients underwent OLT and 125 died. The cumulative incidence of failure (death or OLT) after 1, 2, and 3 years was, respectively, 28, 53, and 62% in patients with AoCLF; 10, 18, and 25% in patients with UD ascites; 17, 31, and 41% in patients with overt ascites; and 8, 12, and 24% in patients with GEVB (P<0.0001). AoCLF is responsible for a relevant proportion of first decompensation in cirrhotic patients and is associated with the poorest outcome. Patients with UD ascites do not have a negligible mortality rate and require clinical monitoring similar to that of patients with overt ascites.

    The objective of the ASMA study was to describe the evolution of light to moderate asthma, newly or recently (12 Pounds months) diagnosed in private pneumology centers, and to search for the predictive factors. In 1995, 251 private pneumologists, throughout Metropolitan France, recruited 396 asthmatic children, 6 to 12 years old (64% boys). The 334 patients eligible for the study were examined every 4 months during 3 years (a mean of 6 controls were conducted out of the expected 9). The data were collected on standardized questionnaires completed by the physicians and notebooks filled-in by the patients the week before each control. This questionnaire comprised two asthma 'control' criteria: "control" of the clinical state, defined as asthma attacks < 1 per week AND nocturnal awakening < 1 per week AND absence of asthma symptoms between attacks on every control visit; "control" of the need for b2 mimetics on request, defined as the non-use throughout the week preceding the control visit. The global clinical state of the cohort rapidly improved once care was initiated: the proportion of children exhibiting at least one attack of asthma per week rapidly dropped to 43% on inclusion and to 13% on the first control visit (4 months), 10% on the second control visit, and then fluctuated at around 8% up until the last control visit. A similar evolution was noted regarding nocturnal asthma attacks. The proportion of patients with prescriptions for inhaled corticosteroids and long-lasting b2-mimetics increased over the three years of follow-up. Analysis of the factors related to the individual 'control' of the clinical state showed a negative effect in family histories of asthma (father) and the presence of smokers in the home, but above all a positive effect of compliance to treatment and particularly its understanding (OR = 2.5; p = 0.03) and respect of the doses (OR = 2.7; p < 0.01).

    To compare the efficacy of two different techniques for vertical bone regeneration at implant placement with particulated autogenous bone at 3 years after loading: resorbable collagen barriers supported by osteosynthesis plates and nonresorbable titanium-reinforced expanded polytetrafluoroethylene barriers. Twenty-two partially edentulous patients requiring vertical bone augmentation were randomly allocated to two treatment groups, each composed of 11 patients. Prosthetic and implant failures, complications, the amount of vertically regenerated bone, and peri-implant marginal bone levels were recorded by independent and blinded assessors. The implant site requiring the most vertical bone regeneration was selected in each patient for bone level assessment. The follow-up time ranged from provisional loading to 3 years after loading. Analysis of covariance and paired t tests were conducted to compare means at the .05 level of significance. No patient dropped out or was excluded at the 3-year follow-up. No prosthetic failures and no implant failures or complications occurred after loading. There was no statistically significant difference in bone loss between the two groups at either 1 year or 3 years. Both groups had gradually lost a statistically significant amount of peri-implant bone at 1 and 3 years (P < .05). After 3 years, patients treated with resorbable barriers had lost a mean of 0.55 mm of bone; patients who had received nonresorbable barriers showed a mean of 0.53 mm of bone loss. Up to 3 years after implant loading, no failures or complications occurred and peri-implant marginal bone loss was minimal. Vertically regenerated bone can be successfully maintained after functional loading.

    Ever wonder about the rain? Beyond the practicality of needing an umbrella, climate researchers have wondered about the science of rainfall for a long time. But it's only in the past few years that they've begun to roll back some of its secrets. One of their tools for doing so is a powerful satellite called the Tropical Rainfall Measuring Mission, or TRMM. Now, after three years of continual operation, project scientists have released dramatic new maps of rainfall patterns gathered across a wide band of the Earth. And with measurements from one of the satellite's advanced sensors, meteorologists are now able to calibrate ground-based rain monitoring systems with greater precision than ever before. A complete accounting of the world's total rainfall has long been a major goal of climate researchers. Rain acts as the atmosphere's fundamental engine for heat exchange; every time a raindrop falls, the atmosphere gets churned up and latent heat flows back into the total climate system. Considering that rainfall is the primary driving force of heat in the atmosphere, and that two thirds of all rain falls in the tropics, these measurements are significant for our understanding of overall climate. The above image shows a one month average of rainfall measurements taken by the TRMM's unique precipitation radar during January of 1998. Areas of low rainfall are colored light blue, while regions with heavy rainfal are colored orange and red. TRMM began collecting data in December of 1997, and continues today.

Among older men with low or low-normal testosterone levels, testosterone administration for 3 years vs placebo did not result in a significant difference in the rates of change in either common carotid artery intima-media thickness or coronary artery calcium nor did it improve overall sexual function or health-related quality of life. Because this trial was only powered to evaluate atherosclerosis progression, these findings should not be interpreted as establishing cardiovascular safety of testosterone use in older men. clinicaltrials.gov Identifier: NCT00287586.

    Microphysics of clouds with the Relaxed Arakawa-Schubert Scheme (McRAS) was upgraded for simulating the Aerosol Indirect Effects (AIE) for water clouds. The AIE comprises of i) Fountoukis and Nenes aerosol activation module for obtaining cloud condensation nuclei; ii) Seifert and Beheng algorithms for precipitation microphysics but with modified accretion constant for the coarse vertical-resolution typical of a global general circulation model (GCM); and iii) Khvorostyanov and Curry parameterization for computing the effective radius ( re) of cloud drops. The upgraded package, named McRAS-AC, was evaluated using the 3-year ARM-SGP Single Column Model (SCM) data. Invoking only the most dominant sulfate aerosols over the region, McRAS-AC simulated realistic annual mean and annual cycles of cloud water, cloud optical thicknesses, cloud drop number concentration, and re. The follow-on SCM-sensitivity simulations showed that accretion of cloud water is sensitive to i) the terminal velocity of hydrometeors produced by autoconversion and ii) cloud height increases due to in-cloud condensation heating. The impact of aerosol mass concentration on the resultant column cloud water, and bulk optical properties of clouds were assessed by using 1/8 to 8 times the average monthly aerosol mass concentration estimates of GOCART aerosol climatology. A log-linear relation between cloud-radiative forcing and aerosol-mass concentration emerged in the simulated data.

    People with major mental illness are over-represented in prison populations however there are few longitudinal studies of prison in-reach services leading to appropriate healthcare over extended periods. We aimed to examine measures of the clinical efficiency and effectiveness of a prison in-reach, court diversion and liaison service over a 3 year period. Secondly, we aimed to compare rates of identification of psychosis and diversion with rates previously reported for the same setting in the 6 years previously. We adopted a stress testing model for service evaluation. All new male remand committals to Ireland's main remand prison from 2012 to 2014 were screened in two stages. Demographic and clinical variables were recorded along with times to assessment and diversion. The DUNDRUM Toolkit was used to assess level of clinical urgency and level of security required. Binary logistic regression was used to assess factors relevant to diversion. All 6177 consecutive remands were screened of whom 1109 remand episodes (917 individuals) received a psychiatric assessment. 4.1 % (95 % CI 3.6-4.6) had active psychotic symptoms. Levels of self-harm were low. Median time to full assessment was 2 days and median time to admission was 15.0 days for local hospitals and 19.5 days for forensic admissions. Diversion to healthcare settings outside prison was achieved for 5.6 % (349/6177, 95 % CI 5.1-6.3) of all remand episodes and admissions for 2.3 % (95 % CI 1.9-2.7). Both were increased on the previous period reported. Mean DUNDRUM-1 and DUNDRUM-2 Triage Security Scores were appropriate to risk and need. We found that a two-stage screening and referral process followed by comprehensive assessment optimised identification of acute psychosis. The mapping approach described shows that it is possible for a relatively small team to sustainably achieve effective identification of major mental illness and diversion to healthcare in a risk-appropriate manner.

    The aim of this prospective, randomized, controlled multicenter study was to determine the 3-year efficacy and stability of the soft and hard tissues at implants with a different geometry that were placed in fresh extraction sockets. Implants with two different configurations, cylindrical (Group A) or conical/cylindrical (Group B) were installed, and healing abutments were attached. Sixteen weeks after implant placement, subjects returned for a re-entry procedure. Prosthetic restorations were delivered 22 weeks after implant placement. Each subject was placed in a 3-year follow-up program, including examinations at yearly visits including various soft tissue and bone level parameters. The percentage of sites that were considered inflamed during the follow-up period was stable and varied between 8.8% and 10.2%. The radiographic examinations documented improved bone levels at the final examination and the mean improvement from baseline (placement of permanent restoration; PR) amounted to 0.17 ± 0.67 mm. More than 70% (54 of 76) of the implants monitored in this study suffered no bone loss during the maintenance period. Moreover, there was an obvious "gain" of interproximal soft tissue volume and at the 3-year examination around 25% of all embrasure gaps were completely filled with "papillae". Both conical/cylindrical and cylindrical implants placed in fresh extraction sockets allowed proper soft and hard tissue healing to occur. At both types of implants, mucosal inflammation was infrequent, marginal bone levels were maintained, and soft tissue volume increased gradually after the placement of the permanent restoration. © 2013 John Wiley & Sons A/S.

    Sander, Rebecca; Trible, Karen A

    2008-01-01

    Two years ago, faculty and students at this rural university setting collaborated to implement a virtual clinical evaluation tool. In recognition of the frustrations involved in coordinating instructor and student input to a hard copy tool, a virtual clinical evaluation tool was created in the form of an Excel spreadsheet. Excel documents have the advantage of immediate retrieval and use by instructors or students, ease of narration by word processing, automatic mathematical computation of formative and summative scores, and data storage through computer archives. Using the online Blackboard course, students and instructors are able to collaboratively input a Likert score for each posted evaluation outcome and word process-related comments about students' clinical performance. An overview of the 2-year implementation of this virtual clinical evaluation tool, as well as the evaluation process, is discussed.

    Moxalactam was administered intravenously or intramuscularly or both in doses of 1 to 12 g/day to 45 patients with clinically significant infections (17 soft tissue or bone, 9 pleuropulmonary, 9 septicemic, 6 urinary tract, and 4 intraabdominal infections). Mean 0.5-h postinfusion levels were 105 micrograms/ml for a 4.0-g dose, 44.7 micrograms/ml for a 2.0-g dose, and 18 micrograms/ml for a 1.0-g dose. We identified 28 isolates of Enterobacteriaceae, 10 Pseudomonas aeruginosa isolates, 9 Staphylococcus aureus isolates, and 15 anaerobic bacterial isolates. A total of 15 patients were clinically cured, 8 patients improved, 13 patients improved initially but suffered subsequent relapses or superinfections, and 10 patients failed therapy. Toxicity was generally minimal (reversible eosinophilia, and mild liver function abnormalities, and elevated prothrombin time). The selection or emergence of resistant organisms in 17 patients during treatment (particularly Pseudomonas, enterococci, and Candida) was a disturbing feature of therapy. Our results were generally favorable, considering the complicated underlying medical problems of this group of patients. PMID:6213198

    1985-01-01

    A review of clinical studies of piperacillin shows that it is valuable for the treatment of respiratory infections due to Enterobacteriaceae, Pseudomonas sp, anaerobes, and mixed flora including anaerobes. Various studies of a total of 420 patients treated with piperacillin for lower respiratory tract infections found that 97% of the patients were cured or markedly improved. Piperacillin has also been found as effective as combination therapy (gentamicin or tobramycin plus carbenicillin or ticarcillin) in the treatment of serious infections, including pneumonia and several caused by gram-negative organisms and anaerobic organisms. A review of the literature on bacteriological responses to piperacillin shows that 126 of 153 (82%) of the susceptible strains could be eradicated. Streptococcus pneumoniae, beta-hemolytic streptococci, Haemophilus influenzae, Peptostreptococcus sp, Bacteroides sp, and Fusobacterium sp have been completely eradicated by treatment with piperacillin. Most of the published studies indicate that therapy with the drug is usually well tolerated.

  2. Clinical evaluation of stereopsis.

    PubMed

    Westheimer, Gerald

    2013-09-20

    Principles of the design and administration of clinical stereopsis tests are outlined. Once the presence of the distinct sense of the third dimension by binocular vision alone and without help from monocular cues has been established in a patient, the examination can proceed to the measurement of stereoscopic acuity. Best results are obtained with high-contrast, sharp, well-articulated and uncrowded elements from easily-recognized target sets, displayed with no time constraints. Polarization is the preferred method of right/left eye separation; time-sharing at a minimum of 60 Hz on computer displays with counterphase occluding goggles is a feasible procedure. Random-dot stereograms are problematic because not all observers can disentangle the coherent global disparity on a first view. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Cellulite is a common female cosmetic concern for which no single treatment option had been proven effective over the long term. A novel tissue stabilized-guided subsicion system (TS-GS system) has demonstrated significant reduction in the appearance of cellulite after treatment. The objective of this extended follow-up period was to assess the effectiveness of TS-GS out to 3 years after initial treatment. After completing an open-label, multicenter, pivotal study, 45 subjects were followed for an extended period of up to 3 years after receiving a single treatment using the TS-GS system. Treatment areas were photographed prior to the procedure and at multiple time points post-treatment throughout the 3 years. In this open-label study, subjects served as their own controls. Effectiveness was assessed based on blinded independent physician panel assessments of improvement from baseline using a cellulite severity scale. Subject aesthetic improvement and patient-reported satisfaction were also collected. The results of this trial supported Food and Drug Administration clearance of the device for the long-term reduction in the appearance of cellulite following TS-GS. These data further demonstrate the safety and efficacy of this treatment with no reduction in treatment benefits out to 3 years.

    Effective diagnosis of tuberculosis is of great importance for transmission control and treatment success. The purpose of this study is to evaluate microscopic examination results of Ehrlich-Ziehl Neelsen (EZN) and Auramine-Rhodamine staining methods and automated BACTEC MGIT 960™ system and Löwenstein-Jensen (L-J) culture results of various clinical samples in the light of recent data from the world and Turkey. Specimens that were sent from various clinics to Sureyyapasa Chest Diseases and Chest Surgery Training and Research Hospital Microbiology Laboratory from January 2012 to December 2015 were evaluated retrospectively. From a total of 62456 samples; 60923 (97.5%) were pulmonary and 1533 (2.5%) were non-pulmonary samples, especially pleura. 2853 (4.6%) Acid-resistant bacilli (ARB) positivity was detected and mycobacterial culture positivity was in total 12.2%. 7076 (93%) and 535 (7%) mycobacteria other than tuberculosis (MOTT) strains were isolated. In 356 specimens the cultures were negative in despite the positive ARB results. Considering mycobacterial culture as the gold standard; the sensitivity, specificity, positive and negative predictive values of ARB microscopy were 32.8%, 99.4%, 87.5% and 91.4%, respectively. The contamination rates in total were within acceptable limits being 2.7% for L-J and 3.8% for MGIT. Analysis of our data indicated that the sensitivity of microscopy is low and it should be evaluated together with the mycobacterial culture to rule out tuberculosis infection. With the use of fluorescent staining and also L-J and MGIT broth together for routine culture since 2013; ARB false negativity rate was observed to fall to 51.7% from 74.1% compared to the years. The follow-up of data such as the sensitivity of microscopy, culture positivity, false-positivity and false-negativity rates and contamination values is of great importance in terms of assessing compliance with laboratory quality standards and contributing to the surveillance

    Twenty-five cases of dermatophytoses caused by Microsporum canis were encountered during a 3-year period (January 2008-December 2010). Their diagnosis was based on detection of fungal elements by direct microscopy and identification of M. canis by fungal culture. There were 17 women and 8 men ; they ranged in age from 4 to 85 years (mean, 34.6). The affected site was the head (n=5), face (n=8), neck (n=5), arm (n=8), leg (n=5), and trunk (n=5) ; exposed sites were those most often affected. A lone eruption was seen in 13 and multiple eruptions in 12 patients. The disease type was tinea corporis in 21 patients, tinea capitis in 5, and a combination of tinea corporis and tinea capitis in one. The disease showed familial onset in 10 patients (5 pairs), including 2 sibling pairs, 2 mother-child pairs, and 1 grandmother-granddaughter pair. Twenty-four patients had a history of contact with animals, and animals kept at home may have served as the infection source (cats in 23 patients and a dog in one). Hairbrush culture of the pets was positive in 9 patients. The patients with a lone eruption were treated with topical antifungal agents, while those with multiple eruptions of tinea capitis and tinea corporis were treated with oral itraconazole or terbinafine hydrochloride for 2-14 weeks, combined with topical antifungal therapy. Although reports of dermatophytoses caused by M. canis have been decreasing, our experience indicates the necessity of considering possible transmission of this disease from pets such as cats.

    The incidence of mold infections in patients with hematologic malignancies continues to increase despite the widespread use of air filtration systems, suggesting the presence of other hospital sources for these molds. Water sources are known to harbor pathogenic molds. We examined samples from water, water surfaces, air, and other environment sources from a bone marrow transplantation unit with optimal air precautions. Molds (Aspergillus species, others) were recovered in 70% of 398 water samples, in 22% of 1311 swabs from plumbing structures and environmental surfaces, and in 83% of 274 indoor air samples. Microscopic examination of the water plumbing lines revealed hyphal forms compatible with molds. Four findings suggest that indoor airborne molds were aerosolized from the water: (1) higher mean airborne concentrations of molds in bathrooms (16.1 colony-forming units [CFU]/m(3)) than in patient rooms (7 CFU/m(3)) and hallways (8.6 CFU/m(3); P =.00005); (2) a strong type and rank correlation between molds isolated from hospital water and those recovered from indoor hospital; (3) lack of seasonal correlation between the airborne mold concentration in outdoor and indoor air; and (4) molecular relatedness between a clinical strain and a water-related strain (previously reported). Hospital water distribution systems may serve as a potential indoor reservoir of Aspergillus and other molds leading to aerosolization of fungal spores and potential exposure for patients.

    to describe the epidemiologic, clinical, and prognostic aspects of the emergency and non-emergency transfers of obstetric patients to Yalgado Ouédraogo University Hospital Center (UHC-YO) in Ouagadougou. this retrospective descriptive study looked at the outcomes of women transferred, on an emergency basis or not, to the obstetrics department of the UHC-YO. The study population comprised all women transferred to the department during 2010, 2011, and 2012. during the study period, there were 9,806 admissions for obstetric disorders: 43% were transfers. The patients' mean age was 26.11 years [(13-49]. Women transferred from health care facilities within the city of Ouagadougou accounted for 96% of the sample. The leading reason for these transfers - emergency or not - was preeclampsia and eclampsia (24.57%). We recorded a total of 161 maternal deaths, for a mortality rate of 3.9%. Approximately 26.55% of the newborns received immediate intensive care and were then transferred to the neonatology department. maternal and neonatal prognosis is always poor in cases transferred to UHC-YO, despite increased funding for emergency obstetric and neonatal care. Increased population awareness of the importance of prenatal consultation and adequate funding for health care facilities to provide equipment for emergency transfers and staff training in the management of obstetric and neonatal emergencies would probably improve these mortality and morbidity rates.

    Immediate implant function has become an accepted treatment modality for fixed restorations in totally edentulous mandibles, whereas experience from immediate function in the edentulous maxilla is limited. The purpose of this study was to report on the medium- and long-term outcomes of a protocol for immediate function of four implants (All-on-4, Nobel Biocare AB, Göteborg, Sweden) supporting a fixed prosthesis in the completely edentulous maxilla. This retrospective clinical study included 242 patients with 968 immediately loaded implants (Brånemark System TiUnite, Nobelspeedy, Nobel Biocare AB) supporting fixed complete-arch maxillary all-acrylic prostheses. A specially designed surgical guide was used to facilitate implant positioning and tilting of the posterior implants to achieve good bone anchorage and large interimplant distance for good prosthetic support. Follow-up examinations were performed at 6 months, 1 year, and thereafter every 6 months. Radiographic assessment of the marginal bone level was performed after 3 and 5 years in function. Survival was estimated at patient level and implant level using the Kaplan-Meier product limit estimation with 95% confidence intervals. Nineteen immediately loaded implants were lost in seventeen patients, giving a 5-year survival rate estimation of 93% and 98% at patient and implant level, respectively. The survival rate of the prosthesis was 100%. The marginal bone level was, on average, 1.52 mm (standard deviation [SD] 0.3 mm) and 1.95 mm (SD 0.4 mm) from the implant/abutment junction after 3 and 5 years, respectively. The high survival rates at patient and implant level indicates that the immediate-function concept for completely edentulous maxillae using the present protocol is viable in the medium- and long-term outcomes. © 2011 Wiley Periodicals, Inc.

    Circulating 25-hydroxyvitamin D (25OHD) levels <75 nmol/L are associated with a nonlinear increase in mortality risk. Such 25OHD levels are common in heart failure (HF). We therefore examined whether oral vitamin D supplementation reduces mortality in patients with advanced HF. Four hundred HF patients with 25OHD levels <75 nmol/L were randomized to receive 4000 IU vitamin D daily or matching placebo for 3 years. Primary endpoint was all-cause mortality. Key secondary outcome measures included hospitalization, resuscitation, mechanical circulatory support (MCS) implant, high urgent listing for heart transplantation, heart transplantation, and hypercalcaemia. Initial 25OHD levels were on average <40 nmol/L, remained around 40 nmol/L in patients assigned to placebo and plateaued around 100 nmol/L in patients assigned to vitamin D. Mortality was not different in patients receiving vitamin D (19.6%; n = 39) or placebo (17.9%; n = 36) with a hazard ratio (HR) of 1.09 [95% confidence interval (CI): 0.69-1.71; P = 0.726]. The need for MCS implant was however greater in patients assigned to vitamin D (15.4%, n = 28) vs. placebo [9.0%, n = 15; HR: 1.96 (95% CI: 1.04-3.66); P = 0.031]. Other secondary clinical endpoints were similar between groups. The incidence of hypercalcaemia was 6.2% (n = 10) and 3.1% (n = 5) in patients receiving vitamin D or placebo (P = 0.192). A daily vitamin D dose of 4000 IU did not reduce mortality in patients with advanced HF but was associated with a greater need for MCS implants. Data indicate caution regarding long-term supplementation with moderately high vitamin D doses. clinicaltrials.gov Idenitfier: NCT01326650.

    This controlled clinical trial aimed to compare the 3-year outcomes of glass fiber posts and composite cores with gold alloy-based posts and cores for the restoration of endodontically treated teeth. One hundred forty-four patients in need of 205 restorations on endodontically treated teeth were selected and followed for 7 to 37 months (mean: 21 ± 9 months). The teeth were primarily stratified based on the remaining tissue available to restore the tooth core with or without a post. Then, randomization allocated the teeth to either test group 1 (prefabricated glass fiber posts), test group 2 (custom-made glass fiber posts), or test group 3 (composite cores without posts). The control group consisted of gold alloy-based posts and cores. All posts/cores were covered with all-ceramic single crowns. Failures were either absolute, such as root fractures or irreparable fractures of the post/core, or relative, such as loss of post retention or reparable fractures of the core. Success and survival probability lifetime curves, corrected for clustering, were drawn for the entire data set. The recall rate at 3 years was 97.1%. Absolute failures consisted of two root fractures and one endodontic failure, while relative failures included three instances of retention loss of the post/core and one post fracture. Because of the low number of events, no statistical tests were performed. The success and survival probabilities over all groups together at 3 years amounted to 91.7% and 97.2%, respectively. After being followed for up to 3 years, both cast gold and composite post and core systems performed well clinically. Longer follow-up times are needed to detect possible significant differences.

    PubMed

    Morrow, Kathleen M; Hendrix, Craig

    2010-12-01

    The clinical evaluation of microbicide formulations presents variable and interacting challenges. Specific domains of acceptability, pharmacokinetics, and toxicity interact with each other to potentially inhibit or enhance a microbicide's efficacy. Each of these is further influenced by application and use parameters in the relative presence (or absence) of vaginal and/or seminal fluids, ultimately impacting effectiveness. Historically, acceptability of formulation and use parameters, and their concomitant behavioral influences, have been considered separately from pharmacokinetics and toxicity. While independent evaluation of these elements is necessary in some respects, we must acknowledge that this approach is not sufficient for the successful development of microbicides. Each needs to be considered in an integrated clinical evaluation strategy. This article presents the rationale for such an approach. This article forms part of a special supplement covering two presentations on clinical evaluation of microbicides from the symposium on "Recent Trends in Microbicide Formulations" held on 25 and 26 January 2010, Arlington, VA.

    The cultivation of Cry1Ab-expressing genetically modified MON810 (Bt maize) has led to public concern in Europe, regarding its impact on nontarget arthropods (NTAs). We have assessed the potential effects of DKC 6451 YG (MON810) maize on canopy NTAs in a farm-scale study performed in Central Spain during 3 years. The study focused on hemipteran herbivores (leafhoppers and planthoppers) and hymenopteran parasitic wasps (mymarids) collected by yellow sticky traps, which accounted for 72% of the total number of insects studied. The dynamics and abundance of these groups varied among years, but no significant differences were found between Bt and non-Bt maize, indicating that Bt maize had no negative effect on these taxa. Nonetheless, the Cry1Ab toxin was detected in 2 different arthropods collected from Bt maize foliage, the cicadellids Zyginidia scutellaris and Empoasca spp. A retrospective power analysis on the arthropod abundance data for our field trials has determined that Z. scutellaris and the family Mymaridae have high capacity to detect differences between the Bt maize and its isogenic counterpart. The use of these canopy NTAs as surrogates for assessing environmental impacts of Bt maize is discussed. © 2016 Institute of Zoology, Chinese Academy of Sciences.

    Sublingual immunotherapy and subcutaneous immunotherapy are effective in seasonal allergic rhinitis. Three years of continuous treatment with subcutaneous immunotherapy and sublingual immunotherapy has been shown to improve symptoms for at least 2 years following discontinuation of treatment. To assess whether 2 years of treatment with grass pollen sublingual immunotherapy, compared with placebo, provides improved nasal response to allergen challenge at 3-year follow-up. A randomized double-blind, placebo-controlled, 3-parallel-group study performed in a single academic center, Imperial College London, of adult patients with moderate to severe seasonal allergic rhinitis (interfering with usual daily activities or sleep). First enrollment was March 2011, last follow-up was February 2015. Thirty-six participants received 2 years of sublingual immunotherapy (daily tablets containing 15 µg of major allergen Phleum p 5 and monthly placebo injections), 36 received subcutaneous immunotherapy (monthly injections containing 20 µg of Phleum p 5 and daily placebo tablets) and 34 received matched double-placebo. Nasal allergen challenge was performed before treatment, at 1 and 2 years of treatment, and at 3 years (1 year after treatment discontinuation). Total nasal symptom scores (TNSS; range; 0 [best] to 12 [worst]) were recorded between 0 and 10 hours after challenge. The minimum clinically important difference for change in TNSS within an individual is 1.08. The primary outcome was TNSS comparing sublingual immunotherapy vs placebo at year 3. Subcutaneous immunotherapy was included as a positive control. The study was not powered to compare sublingual immunotherapy with subcutaneous immunotherapy. Among 106 randomized participants (mean age, 33.5 years; 34 women [32.1%]), 92 completed the study at 3 years. In the intent-to-treat population, mean TNSS score for the sublingual immunotherapy group was 6.36 (95% CI, 5.76 to 6.96) at pretreatment and 4.73 (95% CI, 3.97 to 5

    The use of contracts in grading clinical performance has provided faculty with a solution to two important problems. One has been how to ensure that students are graded consistently among the various faculty who are grading the same clinical component of a course. The second has been to increase the opportunity for individualized attention to student learning needs. We have been pleased to see all the faculty members increase their input and involvement in the continuing modifications of the contract. Although we have taken the major responsibility for the semi-annual revisions of the contract, other faculty members have been increasingly more explicit in their evaluations and suggestions as their experience with the contract has expanded. Their confidence in this method of clinical evaluation has increased with each semester of use. We plan to continue in the refinement of the instrument and will develop materials for the use of other faculty groups who are interested in developing similar contracts. We are also designing a survey to attempt to discover how widespread is the use of contract grading in clinical areas.

    Background The Uzbekistan 1996 Demographic Health Survey reported 60.4% of women of reproductive age (WRA) had low hemoglobin concentrations (<120 g/L), and anemia was an important public health problem. Fortification of wheat flour was identified as an appropriate intervention to address anemia due to the ubiquitous consumption of wheat flour. A National Flour Fortification Program (NFFP) was implemented in 2005. Methodology/Principal Findings After 3-years of the NFFP, a national survey using large country-lot quality assurance sampling was carried out to assess iron, folate, hemoglobin and inflammation status of WRA; the coverage and knowledge of the fortified first grade UzDonMakhsulot (UDM) flour/grey loaf program; and consumption habits of women to investigate the dietary factors associated with anemia. Estimated anemia prevalence was 34.4% (95% CI: 32.0, 36.7), iron depletion 47.5% (95% CI: 45.1, 49.9) and folate deficiency 28.8% (95% CI: 26.8, 30.8); the effect of inflammation was minimal (4% with CRP >5 mg/L). Severe anemia was more prevalent among folate deficient than iron depleted WRA. Presence of UDM first grade flour or the grey loaf was reported in 71.3% of households. Among WRA, 32.1% were aware of UDM fortification; only 3.7% mentioned the benefits of fortification and 12.5% understood causes of anemia. Consumption of heme iron-containing food (91%) and iron absorption enhancers (97%) was high, as was the consumption of iron absorption inhibitors (95%). Conclusions/Significance The NFFP coincided with a substantial decline in the prevalence of anemia. Folate deficiency was a stronger predictor of severe anemia than iron depletion. However, the prevalence of iron depletion was high, suggesting that women are not eating enough iron or iron absorption is inhibited. Fortified products were prevalent throughout Uzbekistan, though UDM flour must be adequately fortified and monitored in the future. Knowledge of fortification and anemia was low, suggesting

    Ibandronate, a nitrogen-containing bisphosphonate, is a bone resorption inhibitor widely used to prevent and treat osteoporosis. To optimize the design for a long-term clinical study of ibandronate, modeling and simulation (M&S) was performed based on the result of population pharmacodynamic analysis using the data of a short-term clinical study. A population pharmacodynamic model was constructed by the urinary C-terminal telopeptide of type I collagen (uCTx) and the lumbar spine bone mineral density (BMD) data obtained in clinical studies, including a phase II study of Japanese osteoporosis patients treated with ibandronate for 6 months. Changes in BMD over a period of 3 years were simulated from the population pharmacodynamic parameters of the patients in this phase II study. The relationship between uCTx and BMD was well described by this modeling. The functions of disease progression and supplemental treatment were incorporated into the model to simulate a long-term clinical study with high accuracy. A long-term clinical study with a 3-year treatment was conducted after this M&S. The percentage change from baseline in observed BMD values were found to be similar to the prospectively simulated values. This study showed that M&S could be a useful and powerful tool for designing and conducting long-term clinical studies when carried out in the following sequence: (1) conduct a short-term clinical study; (2) perform M&S; and (3) conduct the long-term clinical study. Application of this procedure to various other treatment agents will establish the usefulness of M&S for long-term clinical studies and bring further efficiencies to drug development.

    The aims are to define the regression rate in newly diagnosed type 2 diabetes after lifestyle intervention and pharmacological therapy based on a SMBG (self-monitoring of blood glucose) strategy in routine practice as compared to standard HbA1c-based treatment and to assess whether a supervised exercise program has additional effects. St Carlos study is a 3-year, prospective, randomized, clinic-based, interventional study with three parallel groups. Hundred and ninety-five patients were randomized to the SMBG intervention group [I group; n = 130; Ia: SMBG (n = 65) and Ib: SMBG + supervised exercise (n = 65)] and to the HbA1c control group (C group) (n = 65). The primary outcome was to estimate the regression rate of type 2 diabetes (HbA1c <6 % on metformin treatment). After 3 years of follow-up, diabetes regression was achieved by 56 patients, 6 (9.2 %) from the C group, 21 (32.3 %) from the Ia group and 29 (44.6 %) from the Ib group. RR (95 % CI) for diabetes regression in the intervention group (Ia + Ib) was 4.5 (2.1-9); p < 0.001 and remained after stratification by gender, age and BMI. This difference was associated with healthier changes in lifestyle and greater weight loss. RR for a weight loss >4 kg was 3.6 (1.8-7); p < 0.001. This study shows that the use of SMBG in an educational program effectively increases the regression rate in newly diagnosed type 2 diabetic patients after 3 years of follow-up. These data suggest that SMBG-based programs should be extended to primary care settings where diabetic patients are usually attended.

    Advances in cardiopulmonary bypass equipment have played a critical role in improving outcomes for cardiac surgery patients. Recent advancements include reduced priming volumes, biocompatible coatings and gaseous microemboli handling, as well as the incorporation of an arterial filter into the oxygenator.The purpose of this study was to conduct a comprehensive clinical evaluation of adult oxygenators on the market. Oxygenators assessed included the Sorin Synthesis(®) (n = 30), the Sorin Inspire 6F(®) (n = 10) and Inspire 8F(®) (n = 30), the Terumo FX15(®) (n = 13) and FX25(®) (n = 30), the Maquet Quadrox-i(®) (n = 30) and the Medtronic Fusion(®) (n = 30). Parameters assessed included functional prime volumes, gas exchange, pressure gradients and the effects on patient hematology.The Synthesis had the largest functional prime volume (1426 ml), the FX15 the lowest (956 ml). The Inspire 6F, 8F and Fusion had the greatest O2 transfer. The Sorin oxygenators required the lowest sweep gas flows to obtain a PaCO2 of 40 mmHg. The Sorin oxygenators had the largest pressure gradients. While no differences were observed for hemoglobin and platelet levels post cross-clamp removal, the Sorin Synthesis and Inspire 8F had the largest increases in white blood cell (WBC) counts (122% and 141% of baseline, respectively) and neutrophils (162% and 185% of baseline, respectively).The data demonstrate that no single product is superior in all aspects. The choice of ideal oxygenator depends on the aspect(s) of oxygenator performance the perfusion team believes most clinically acceptable based on available data. © The Author(s) 2015.

  7. The Novel Design of Zirconium Oxide-Based Screw-Retained Restorations, Maximizing Exposure of Zirconia to Soft Peri-implant Tissues: Clinical Report After 3 Years of Follow-up.

    PubMed

    Linkevicius, Tomas

    Current use of zirconium oxide (ZrO₂)-based screw-retained restorations does not guarantee maximum contact of soft peri-implant tissues with ZrO₂, because veneering porcelain usually covers the major subgingival part of the restoration. Ceramics preclude direct interaction between zirconia and soft tissue cells, thus reducing biocompatibility and benefit to the patient. The four case reports discussed in this article describe the new design modality of the ZrO₂ screw-retained restorations, in which zirconia is exposed to the tissues and no veneering porcelain is located below the gingival margin. The article also shows the impact of this treatment on soft peri-implant tissues after 3 years of follow-up. Soft tissue recession, vestibular contour, bleeding on probing, and probing depth were evaluated.

    Summary Objective To compare the population prevalence, inter-relationships, risk factor profiles and clinical characteristics of subsets of symptomatic hand osteoarthritis (OA) with a view to understanding their relative frequency and distinctiveness. Method 1076 community-dwelling adults with hand symptoms (60% women, mean age 64.7 years) were recruited and classified into pre-defined subsets using physical examination and standardised hand radiographs, scored with the Kellgren & Lawrence (K&L) and Verbruggen–Veys grading systems. Detailed information on selected risk factors was obtained from direct measurement (Body Mass Index (BMI)), self-complete questionnaires (excessive use of hands, previous hand injury) and medical record review (hypertension, dyslipidaemia, type 2 diabetes). Hand pain and disability were self-reported at baseline and 3-year follow-up using Australian/Canadian Osteoarthritis Hand Index (AUSCAN). Results Crude population prevalence estimates for symptomatic hand OA subsets in the adult population aged 50 years and over were: thumb base OA (22.4%), nodal interphalangeal joint (IPJ) OA (15.5%), generalised hand OA (10.4%), non-nodal IPJ OA (4.9%), erosive OA (1.0%). Apart from thumb base OA, there was considerable overlap between the subsets. Erosive OA appeared the most distinctive with the highest female: male ratio, and the most disability at baseline and 3-years. A higher frequency of obesity, hypertension, dyslipidaemia, and metabolic syndrome was observed in this subset. Conclusion Overlap in the occurrence of hand OA subsets poses conceptual and practical challenges to the pursuit of distinct phenotypes. Erosive OA may nevertheless provide particular insight into the role of metabolic and cardiovascular risk factors in the pathogenesis of OA. PMID:23954700

    Four human coronaviruses (HCoV-229E, HCoV-HKU1, HCoV-NL63, and HCoV-OC43) are associated with a range of respiratory outcomes, including bronchiolitis and pneumonia. Their epidemiologies and clinical characteristics are poorly described and are often reliant on case reports. To address these problems, we conducted a large-scale comprehensive screening for all four coronaviruses by analysis of 11,661 diagnostic respiratory samples collected in Edinburgh, United Kingdom, over 3 years between July 2006 and June 2009 using a novel four-way multiplex real-time reverse transcription-PCR (RT-PCR) assay. Coronaviruses were detected in 0.3 to 0.85% of samples in all age groups. Generally, coronaviruses displayed marked winter seasonality between the months of December and April and were not detected in summer months, which is comparable to the pattern seen with influenza viruses. HCoV-229E was the exception; detection was confined to the winter of 2008 and was sporadic in the following year. There were additional longer-term differences in detection frequencies between seasons, with HCoV-OC43 predominant in the first and third seasons and HCoV-HKU1 dominating in the second (see Results for definitions of seasons). A total of 11 to 41% of coronaviruses detected were in samples testing positive for other respiratory viruses, although clinical presentations of coronavirus monoinfections were comparable to those of viruses which have an established role in respiratory disease, such as respiratory syncytial virus, influenza virus, and parainfluenza viruses. The novel multiplex assay for real-time pan-coronavirus detection enhances respiratory virus diagnosis, overcomes potential diagnostic problems arising through seasonal variation in coronavirus frequency, and provides novel insights into the epidemiology and clinical implications of coronaviruses.

    No data exist on the effects of conditioning exercise at foal age on workload and subsequent clinical injury rate during their 2- and 3-year-old racing careers. To investigate the effects of subjecting TB foals to conditioning exercise prior to the start of race training on: the workload required to reach a level of fitness sufficient to compete; and the prevalence of orthopaedic injury during the first 2 seasons of their racing careers. Twenty 18-month-old TBs, 12 subjected to conditioning exercise at foal age (CONDEX) and 8 exercised spontaneously at pasture only (PASTEX) were trained and entered in competitive events. Workload was quantified using the cumulative workload index (the product of average velocity and distance at a specific gait) and the animals were monitored clinically and radiographically for signs of musculoskeletal disorders. Workload to reach the desired fitness level was similar for CONDEX and PASTEX. CONDEX performed more prerace training sessions as 2-year-olds (P<0.05). The incidence of orthopaedic injuries was low in both groups and there were no differences in the occurrence of orthopaedic ailments. PASTEX animals tended to show signs of musculoskeletal disorders earlier than CONDEX animals. This time difference was significant for metacarpophalangeal joint pain on flexion, reduced carpal flexion and hindlimb lameness (P<0.05). Subjecting TB foals to conditioning exercise early in life does not have adverse effects on racing careers at ages 2 and 3 years, and does not influence the workload needed to reach a fitness level that is sufficient for racing. The lack of negative effects and the indications of some positive effects of early conditioning exercise in the Thoroughbred encourage further large-scale comparative studies.

    The authors sought to compare the safety and efficacy of the biocompatible durable-polymer zotarolimus-eluting stent with the biodegradable-polymer biolimus-eluting stent in unselected coronary patients. Biodegradable-polymer biolimus-eluting stents are superior to first-generation durable-polymer drug-eluting stents in long-term randomized all-comer trials. Long-term data comparing them to second-generation durable-polymer drug-eluting stents are lacking. The study was a randomized, multicenter, all-comer, noninferiority trial in patients with chronic stable coronary artery disease or acute coronary syndromes and at least 1 coronary artery lesion requiring treatment with a drug-eluting stent. Endpoints included major adverse cardiac events (MACE), a composite of safety (cardiac death and myocardial infarction not clearly attributable to a non-target lesion) and efficacy (target lesion revascularization); the individual endpoints of MACE; all-cause mortality; any myocardial infarction; target vessel revascularization; and definite or probable stent thrombosis at 36 months. From March 2011 to August 2012, 2,999 patients were randomly assigned (1:1) to receive either the zotarolimus-eluting (1,502 patients) or the biolimus-eluting (1,497 patients) stent. At 3-year follow-up, MACE occurred in 128 (8.6%) patients assigned to the durable-polymer zotarolimus-eluting stent and in 144 (9.6%) assigned to the biodegradable-polymer biolimus-eluting stent (p = 0.36). Occurrence of cardiac death (2.7% vs. 3.4%), myocardial infarction not clearly attributable to a non-target lesion (2.7% vs. 2.5%), and target lesion revascularization (5.4% vs. 5.5%) did not differ significantly between the 2 groups. Definite very late stent thrombosis occurred in 6 (0.4%) patients assigned to the durable-polymer zotarolimus-eluting stent and in 10 (0.7%) assigned to the biodegradable-polymer biolimus-eluting stent (p = 0.33).

    Background To date, only influenza and RSV testing are recommended for respiratory viruses’ detection in paediatric units. In this study, we described, according to seasons, ages and clinical units, the results obtained in children (<15 years old) by multiplex-PCR (mPCR) tests allowing a quick and wide range detection of all respiratory viruses. These results were also compared with RSV specific detection. Methods All nasopharyngeal mPCR and RSV tests requested by clinicians in our French teaching hospitals group between 2011 and 2014 were retrospectively included. All repeated samples for the same children in the same month were discarded. Results Of the 381 mPCR tests (344 children) performed, 51.4% were positive. Positivity and viral co-infection rates were higher in the 6–36 months old strata (81% and 25%, p<0.0001 and p = 0.04, respectively). Viral distribution showed strong variations across ages. During specific influenza epidemic periods, only 1/39 (2.5%) mPCR tests were positive for influenza and 19/39 (48.7%) for other viruses. During specific RSV epidemic periods, only 8/46 (17.4%) mPCR tests were positive for RSV and 14/46 (30.4%) for other viruses. 477/1529 (31.2%) of RSV immunochromatography-tests were positive. Among the negatives immunochromatography-test also explored by mPCR, 28/62 (31%) were positive for other respiratory viruses. Conclusion This study provides a wide description of respiratory viruses’ distribution among children in hospital settings using mPCR over 3 years. It emphasizes the number of undiagnosed respiratory viruses according to the current diagnosis practice in France and gives a better picture of respiratory viruses identified in hospital settings by mPCR all over the year in France.

    When possible, living donor transplantation represents the best therapeutic strategy for patients suffering from chronic renal failure. Studying the donor allows a complete and thorough clinical, laboratory and instrumental assessment that guarantees good organ function whilst protecting the health of the donor. The main parameters considered within this framework are age, renal function, nephrological complications, comorbidities (diabetes, hypertension, obesity, etc.), malignancies, and infection. Moreover, particular attention is paid to the sociopsychological aspects of the donation, particularly related to the donor, the recipient, and the entire family situation.

    The objectives of this project were to evaluate patient satisfaction with the clinical video telehealth (CVT) pain management clinic, and to evaluate possible benefits of this clinic. Data collected included the distance from the patient's home to the main Department of Veterans Affairs (VA) medical center, the distance from the patient's home to the community based outpatient clinic (CBOC), travel distance saved for the patient, and travel pay status. Following CVT clinic appointments patients were asked to complete a written feedback assessment to evaluate patient satisfaction. All data were analyzed using descriptive statistics. Veterans saved 8,981 miles in travel distance, and the VA saved $2,317.51 due to averted travel reimbursement. There was a 90% satisfaction rate with the CVT pain management clinic services, and 90% of patients agreed that they would recommend telehealth to other veterans. Overall, patients are satisfied with the CVT pain management clinic. Furthermore, the substantial miles saved for the patients, as well as the cost savings for the VA, indicates that this service has tangible benefits. As this clinic continues to operate, it can be expected that miles saved for patients and cost savings for the VA will continue to grow.

    The aim of the study was to compare the clinical performance, quantitative and qualitative wear patterns of conventional hybrid (Tetric Ceram), micro-filled hybrid (Gradia Direct Posterior) and nano-hybrid (Tetric EvoCeram, TEC) posterior composite restorations in a 3-year randomised clinical trial. Sixteen Tetric Ceram, 17 TEC and 16 Gradia Direct Posterior restorations were placed in human molars and evaluated at baseline, 6, 12, 24 and 36 months of clinical service according to US Public Health Service criteria. The gypsum replicas at each recall were used for 3D laser scanning to quantify wear, and the epoxy resin replicas were observed under scanning electron microscope to study the qualitative wear patterns. After 3 years of clinical service, the three hybrid restorative materials performed clinically well in posterior cavities. Within the observation period, the nano-hybrid and micro-hybrid restorations evolved better in polishability with improved surface gloss retention than the conventional hybrid counterpart. The three hybrid composites showed enamel-like vertical wear and cavity-size dependant volume loss magnitude. Qualitatively, while the micro-filled and nano-hybrid composite restorations exhibited signs of fatigue similar to the conventional hybrid composite restorations at heavy occlusal contact area, their light occlusal contact areas showed less surface pitting after 3 years of clinical service.

  19. Clinical pathways: a tool to evaluate clinical learning.

    PubMed

    Bradshaw, M J

    1999-01-01

    Clinical pathways are a means by which an instructor can objectively and effectively evaluate student learning and progress toward clinical outcomes. An advantage to use of pathways in one-time experiences is that the pathway serves as a criterion-based frame of reference for both student and instructor, since the criteria are the same as for other clinical experiences in that course. The faculty member thus has an objective measure of student learning and performance, and the student always knows the measure on which she or he will be evaluated. Clinical pathways are limited to brief experiences and are not designed to show professional growth and progress in learning over time. A pathway could be designed, however, to appraise critical thinking and professional behaviors associated with spontaneous incidents, such as a problem patient. Nurse educators can use pathways as a creative means to address student responses in a variety of situations.

    The quality of all clinical decision-making, as well as power and precision in clinical research results, depends fundamentally on the quality of the measures used. Yet evaluations of the quality of clinical measures likely to be used either in clinic or research applications are difficult to execute or to critique because the criteria for judging such studies are so ill-defined. Here a set of guidelines is proposed, modeled on CONSORT guidelines for randomized clinical trials, first defining the terms often inconsistently used in the research literature and then identifying certain errors that seem to recur in evaluation studies.

    Clinical networks have been designed as a cross-organisational mechanism to plan and deliver health services. With recent concerns about the effectiveness of these structures, it is timely to consider an evidence-informed approach for how they can be developed and evaluated. To document an evaluation framework for clinical networks by drawing on the network evaluation literature and a 5-year study of clinical networks. We searched literature in three domains: network evaluation, factors that aid or inhibit network development, and on robust methods to measure network characteristics. This material was used to build a framework required for effective developmental evaluation. The framework's architecture identifies three stages of clinical network development; partner selection, network design and network management. Within each stage is evidence about factors that act as facilitators and barriers to network growth. These factors can be used to measure progress via appropriate methods and tools. The framework can provide for network growth and support informed decisions about progress. For the first time in one place a framework incorporating rigorous methods and tools can identify factors known to affect the development of clinical networks. The target user group is internal stakeholders who need to conduct developmental evaluation to inform key decisions along their network's developmental pathway.

    The Remote Primary Health Care Manuals (RPHCM) project team manages the development and publication of clinical protocols and procedures for primary care clinicians practicing in remote Australia. The Central Australian Rural Practitioners Association Standard Treatment Manual, the flagship manual of the RPHCM suite, has been evaluated for accessibility and acceptability in remote clinics three times in its 20-year history. These evaluations did not consider a theory-based framework or a programme theory, resulting in some limitations with the evaluation findings. With the RPHCM having an aim of enabling evidence-based practice in remote clinics and anecdotally reported to do so, testing this empirically for the full suite is vital for both stakeholders and future editions of the RPHCM. The project team utilized a realist evaluation framework to assess how, why and for what the RPHCM were being used by remote practitioners. A theory regarding the circumstances in which the manuals have and have not enabled evidence-based practice in the remote clinical context was tested. The project assessed this theory for all the manuals in the RPHCM suite, across government and aboriginal community-controlled clinics, in three regions of Australia. Implementing a realist evaluation framework to generate robust findings in this context has required innovation in the evaluation design and adaptation by researchers. This article captures the RPHCM team's experience in designing this evaluation. © 2015 John Wiley & Sons, Ltd.

    1993-05-01

    The purposes of this study were to describe how clinical managers evaluate the performance of clinical dietitians and to examine managers' opinions about performance appraisal. Managers from 55 acute-care hospitals in seven midwestern states responded to a telephone survey about their appraisal of the performance of clinical dietitians. Most of the clinical managers had developed criteria with written standards for evaluating performance. Respondents evaluated the dietitians once a year and relied primarily on chart audits, other work samples, and critical incidents to judge performance. Managers in 32 of the hospitals asked their subordinates to complete a self-appraisal, and almost all of the managers negotiated with the dietitians to identify goals for professional improvement. Respondents' reasons for conducting performance appraisals were indicative of a participative management style. During the interviews, many clinical managers requested help in improving their performance appraisal systems, which suggests a need for additional training in conducting performance appraisals. The findings indicate that most clinical managers were following recommended guidelines for conducting performance appraisals.

    Background This study evaluated the correlation and role of resilience and resilience factors in predicting suicidal ideation and attempts in veterans. Methods In this 3-year longitudinal study, one hundred and seventy-six Iraq and Afghanistan War veterans were evaluated for a number of clinical and demographic variables. Longitudinal follow-up was performed approximately 3 years. Results Resilience at the initial assessment predicted lower suicidality at follow-up, controlling for suicidality at the initial assessment, suggesting a protective effect for resilience. With respect to specific domains of resilience, secure relationships and positive acceptance of change significantly predicted lower suicidality. Conclusions These findings have important implications for clinical care and for guiding future research efforts to increase resilience among returning soldiers. PMID:23376871

    Today's sutures are the result of a 4000-year innovation process with regard to their materials and manufacturing techniques, yet little has been done to enhance the therapeutic value of the suture itself. In this review, we explore the historical development, regulatory database and clinical literature of sutures to gain a fuller picture of suture advances to date. First, we examine historical shifts in suture manufacturing companies and review suture regulatory databases to understand the forces driving suture development. Second, we gather the existing clinical evidence of suture efficacy from reviewing the clinical literature and the Food and Drug Administration database in order to identify to what extent sutures have been clinically evaluated and the key clinical areas that would benefit from improved suture materials. Finally, we apply tissue engineering and regenerative medicine design hypotheses to suture materials to identify routes by which bioactive sutures can be designed and passed through regulatory hurdles, to improve surgical outcomes. Our review of the clinical literature revealed that many of the sutures currently in use have been available for decades, yet have never been clinically evaluated. Since suture design and development is industry driven, incremental modifications have allowed for a steady outflow of products while maintaining a safe regulatory position and limiting costs. Until recently, there has been little academic interest in suture development, however the rise of regenerative medicine strategies is shifting the suture paradigm from an inert material, which mechanically approximates tissue, to a bioactive material, which also actively promotes cell-directed repair and a positive healing response. These materials hold significant therapeutic potential, but could be associated with an increased regulatory burden, cost, and clinical evaluation compared with current devices.

    Background Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of intensive care unit admission, which results in high hospital mortality. Targeted temperature management (TTM) was introduced several years ago and is considered to improve neurological and mortality outcomes. This management process was implemented in our hospital in 2012, which was expected to improve the standard of care in OHCA patients. Purpose We aimed to report the clinical and mortality outcomes after TTM was introduced to our hospital in 2012. Patients and methods An analysis of data from the Medical Intensive Care Unit-TTM registry between 2012 and 2015 was performed. After successful cardiopulmonary resuscitation, TTM was applied to all OHCA patients regardless of causes if there was no contraindication. The Cerebral Performance Category scale score and other clinical outcomes were recorded and analyzed. Results Out of 23 patients, 87% were male and the mean age was 54.5±18.1 years. The causes of OHCA from cardiac etiology comprised 52.2%. The most common initial cardiac rhythm was ventricular fibrillation (47.8%). The survival rate to hospital discharge was 47.8% (11/23), but neurological outcomes were in a persistent vegetative state (8/11, 72.7%). The group with poor neurological outcomes had a significantly higher Acute Physiologic Assessment and Chronic Health Evaluation II score than the group with good neurological outcomes (22.9±4.2 vs 16.0±3.6, P=0.01). In the multivariate analysis, initial shockable rhythm was associated with survival at hospital discharge (odds ratio 10.1, 95% confidence interval 1.1–94.3, P=0.04). Conclusion TTM in OHCA patients gave better mortality benefits compared to our previous records, despite poor neurological outcomes. Ventilator-associated pneumonia was the major complication of TTM. Therefore, TTM should be considered in OHCA patients, especially in shockable rhythms, after return of spontaneous circulation. PMID:27660500

    Ebola virus disease (EVD) was first described over 40 years ago, but no treatment has been approved for humans. The 2013-2016 EVD outbreak in West Africa has expedited the clinical evaluation of several candidate therapeutics that act through different mechanisms, but with mixed results. Nevertheless, these studies are important because the accumulation of clinical data and valuable experience in conducting efficacy trials under emergency circumstances will lead to better implementation of similar studies in the future. Here, we summarize the results of EVD clinical trials, focus on the discussion of factors that may have potentially impeded the effectiveness of existing candidate therapeutics, and highlight considerations that may help meet the challenges ahead in the quest to develop clinically approved drugs.

    Benign prostatic hyperplasia (BPH) is a very common condition, related to aging and causing symptoms, called lower urinary tract symptoms. On account of its huge prevalence, it is important for clinicians who are involved in the management of patients with BPH to be aware of the very strict recommendations for BPH evaluation. In this article, we describe the different steps and procedures doctors should follow to evaluate these patients; symptoms and signs of BPH are reviewed, as well as the clinical evaluation steps and examinations available. The basic evaluation of the patients with BPH should include, according to the recommendations of the most relevant international guidelines, lower urinary tract symptoms evaluation with appropriate symptom scores, digital rectal examination, voiding charts, prostate-specific antigen and creatinine measurement, urinalysis, and imaging of the urinary tract.

    Obesity is a complex disorder that requires a multidisciplinary treatment approach. This review evaluated 3-year outcomes of a very-low-energy diet (VLED)-based programme at a tertiary hospital multidisciplinary weight management clinic. Medical records of all patients who agreed to undertake the VLED programme and who did not undergo bariatric surgery during the 3-year follow-up period were examined. Baseline data collection included demographic and anthropometric characteristics, childhood onset of obesity and co-existing medical conditions. Weight was modelled using a linear mixed effects analysis. Logistic regression analyses were used to model the probability of continuing to attend the clinic and to identify pre-treatment factors associated with longer duration of attendance. Data from 1109 patients were included. A total of 231 patients (19.2%) were still attending the clinic 3 years after their initial appointment. Mean weight loss among patients who attended the clinic for 3 years was 6.4 kg (3.5%, 95% confidence interval [CI] 2.8, 4.2%). People who were prescribed pharmacotherapy maintained greater weight loss at 3 years (7.7% vs. 2.3% without pharmacotherapy, 95% CI for difference 3.9, 7.0%). People who had an onset of obesity in childhood, who had co-existing hypertension or coronary artery disease, and who did not currently smoke were more likely to continue to attend the clinic for up to 3 years. In summary, in an outpatient weight management clinic, patients who undertook a VLED-based programme and continued in follow-up achieved a clinically significant weight loss at 3 years, particularly if pharmacotherapy was used for weight loss maintenance.

    PGD represents an alternative within prenatal diagnosis services, which avoids terminating affected on-going pregnancies. In Greece, prevention programmes for haemoglobinopathies, including the option of prenatal diagnosis, are well established. Following optimization of a single-cell genotyping strategy (designed to be applicable for the majority of beta-thalassaemia major or sickle thalassaemia genotype interactions) along with close collaboration with an IVF unit, we integrated the option of PGD for at-risk couples with a problematic reproductive history. A total of 59 couples requesting PGD were counselled, of whom 41 initiated 63 PGD cycles. Following standard assisted reproduction treatment for oocyte retrieval, 20 cycles were cancelled (too few oocytes and/or poor quality embryos), but in 43 cycles single blastomeres were biopsied from 3 day embryos and genotyped (total 302). Diagnosis was achieved for 236 embryos, and 100 of 125 unaffected embryos were transferred. Sixteen pregnancies were established, although six were lost within the first trimester. Ten pregnancies underwent second trimester prenatal diagnosis, with nine pregnancies (13 babies: six singletons, two twins and one triplet) confirmed unaffected, although one singleton was a PGD misdiagnosis and terminated. The triplet pregnancy was selectively reduced to twins, and nine pregnancies went to term, with 12 healthy babies born. This report highlights advantages, limitations and approaches towards improvement when incorporating PGD within genetic services for a common recessive disease.

    The focus of this study was on the development and field-testing of a set of behaviorally anchored rating scales for evaluating the clinical performance of dietetic students. The scales emphasized the application of skills and knowledge. A variation of the Smith-Kendall technique was used to develop the scales. The 42 participants involved in instrument development included dietetic students, didactic and clinical instructors, and dietetic practitioners. The completed instrument contained 8 dimension statements and 70 behavioral anchors. The instrument was field-tested in 16 clinical rotations within 8 dietetic education programs. Evaluators not only rated student performance but also critiqued the format and content of the scales. The mid-to-upper portions of each scale were used most frequently, and little score variation within or across programs was noted. The scales were deemed appropriate for formative evaluation; however, some evaluators who had to grade students' performance expressed a desire for performance standards defined in terms of grades. Because the process used to develop the instrument facilitated the articulation of performance criteria, it is recommended as a practical approach to setting performance standards.

    Measurement instruments to assess user satisfaction with Clinical Information Systems (CIS) and with the implementation of CIS are needed as part of multi-faceted evaluation of CIS. Seven years of experience in developing measurement instruments to assess staff satisfaction with CIS preceded the development effort that created the Clinical Information System Evaluation Scale (CISIES). The scale was developed using precursors of the CISIES and it was guided by an expert panel. Following its construction the 37-item measurement instrument was piloted as part of the assessment of a Critical Care Clinical Information System implementation at a medical center in Florida, USA. Results indicated satisfaction with the implementation, although not strong, at the time of administration. The results of the CISIES administration were used by informaticians at the research site to plan and execute an intervention to improve satisfaction with the implementation. Re-administration of the CISIES at the site to evaluate the success of this intervention is planned. The CISIES was found to be a useful instrument, easy to administer, acceptable to respondents, easy to score and understandable by non-researcher at the study site. Early indications are that it will be useful in the formative and summative evaluation of CIS implementations.

    Masticatory performance is determined not only through the speed of mastication, or by the quantity of food ingested; it also depends on the structures and functional integration of the stomatognathic system (SS). This study investigated differences in the SS and orofacial motricity between obese and normal--weight women. A total of 18 obese women, with an average age of 28 ± 7.3 years and an average body mass index (BMI) of 37.4 ± 5.1 Kg/m2, and 18 normal--weight women, with an average age of 26 ± 7.6 years and an average BMI of 20.7 ± 1.8 kg/m2, took part in the study. During the speech therapy evaluation, chewing, the number of chewing strokes, and swallowing were observed. The posture, mobility and tonus of lips and tongue, morphology, mobility and tonus of cheeks were designated as normal or altered. The electrical activity of the anterior temporalis, the masticatory muscle was evaluated for both groups using surface electromyography (EMG), which was expressed in microvolts (pV) and registered as Root Mean Squares. Significant differences were found between the two groups in clinical evaluation. In surface EMG, the obese group showed asymmetry of electrical activity of the anterior temporalis. This study suggests that speech therapist investigation of the SS should be combined with interdisciplinary obesity management.

    2015-11-01

    Clinical guidelines are documents to help professionals and patients select the best diagnostic or therapeutic option. Elaborating guidelines requires an efficient literature search and a critical evaluation of the articles found to select the most appropriate ones. After that, the recommendations are formulated and then must be externally evaluated before they can be disseminated. Even when the guidelines are very thorough and rigorous, it is important to know whether they fulfill all the methodological requisites before applying them. With this aim, various scales have been developed to critically appraise guidelines. Of these, the AGREE II instrument is currently the most widely used. This article explains the main steps in elaborating clinical guidelines and the main aspects that should be analyzed to know whether the guidelines are well written.

    The acquisition of competences (the set of knowledge, skills and attitudes required to perform a job to a professional level) is considered a fundamental part of medical training. Dermatology competences should include, in addition to effective clinical interviewing and detailed descriptions of skin lesions, appropriate management (diagnosis, differentiation, and treatment) of common skin disorders and tumors. Such competences can only be acquired during hospital clerkships. As a way of certifying these competences, we propose evaluating the different components as follows: knowledge, via clinical examinations or critical incident discussions; communication and certain instrumental skills, via structured workplace observation and scoring using a set of indicators; and attitudes, via joint evaluation by staff familiar with the student.

    The purpose of this study was to evaluate the clinical performance of surface-retained adhesive composite fixed partial dentures reinforced by an ultra-high molecular weight polyethylene (UHMWP) fiber (Ribbond THM). Twenty-three surface-retained fiber reinforced composite (FRC) fixed partial dentures (FPD) were placed by two operators in 23 patients, each with a single missing tooth. The restorations included prefabricated composite resin pontics, and no preparations were done on the lingual surfaces of the abutment teeth. The patients were recalled for examinations every year for up to 3 years. Restorations were evaluated directly using the modified Ryge criteria. The minimum observation period was 1 year and the maximum observation period was 3 years. At baseline, 23 restorations were graded as Alpha for all parameters. At one year and two years (n = 21), three Bravos for wear resistance and surface texture/gingival inflammation and two Bravos for color match were observed. Twenty-one of 23 restorations were retained at the end of two years (91.3%) and 78.3% were retained after a maximum of 3 years. The results of this clinical study suggestthat UHMWP FRC FPDs are quite acceptable at least forthree years. However, further clinical investigations are still needed for improved long-term clinical performance.

    The aim of the present study was to evaluate the prevalence of malocclusion traits and sucking habits among 3-year-old children. A sample of 457 3-year-old children (234 girls and 223 boys) was obtained from three Public Dental Health clinics in Orebro County Council, Sweden. Data from clinical examination and a questionnaire were used to determine malocclusion traits, sucking habits, snoring and breathing pattern including nocturnal breathing disturbances. The results showed that 70% had one or more malocclusion traits at 3 years of age. The most common malocclusion traits were anterior open bite (50%), Class II occlusion (26%), increased overjet (23%) and posterior crossbite (19%). The prevalence of sucking habit was 66% and dummy sucking was dominating and in connection with more malocclusion traits than finger/thumb sucking. A significant association was found between the sucking habits and the most prevalent malocclusions, anterior open bite, Class II occlusion, increased overjet and posterior crossbite. In conclusion, the prevalence of malocclusion traits in 3-year-old children was high. Sucking habits was highly prevalent and dummy sucking resulted in more malocclusion traits than finger/thumb sucking did.

    The manufacturing variability of frequent replacement toric soft lenses is such that some resulting variation in clinical performance can be expected. The purpose of this study was to evaluate the effect of manufacturing variability on the clinical performance of three frequent replacement toric soft contact lenses. This was a three-part study in which 12 to 14 subjects were enrolled for each part. In each part, subjects were preadapted to the lens type 1 month prior to the assessment visits. Subjects wore a total of 12 test lenses in one eye and, in each case, the clinical performance was compared with a control lens of the same type worn in the other eye that was removed between assessments but not replaced. The study lenses were Acuvue Toric (Vistakon), Focus Toric (Ciba Vision) and FreshLook Toric (Wesley lessen). Two lens types (Focus Toric and FreshLook Toric) showed significantly greater variability with the test lenses compared with the nonreplaced control lenses with several variables: lens fit, visual acuity, and subjective vision quality. One lens (Focus Toric) also showed greater variability of orientation position, and another (Acuvue Toric) showed greater variability in subjective vision quality. The study demonstrated variability in aspects of clinical performance, which appear to be linked to variability of manufacturing output. With toric soft lenses used on a frequent replacement basis, better reproducibility is needed if consistent clinical performance is to be maintained.

Sixty-six patients were included in the study (29 with epididymitis, 8 with testicular torsion and 12 with torsion of the appendix testis, 4 with scrotal abscesses, 5 with scrotal swelling, and 1 with inflamed epididymal cyst). The duration of symptoms ranged from 6 h to 4 days with a peak on the second day. Urine cultures and viral testes were negative in all patients. Color Doppler ultrasound was diagnostic for epididymitis in 28 patients (96.6%). Systemic intravenous antibiotics were given in all 29 patients with epididymitis. No patient showed signs of testicular atrophy in the follow-up. The increasing incidence of epididymitis should question the policy of routine exploration of the acute scrotum in children. The history and physical examination cannot reliably identify those boys who can be managed conservatively. Color Doppler ultrasound is a useful adjunct in the evaluation of the acute scrotum when physical findings are equivocal but it can also be misleading.

    A random retrospective review of the Teen Obstetrical Parenting Perinatal Services (TOPPS) clinic medical records for 1985 to 1989 was completed on 120 adolescent mothers (30 charts for each year). The purpose of this study was to evaluate maternal and infant outcomes related to the goals of the TOPPS clinic located at University Hospital on the UAMS campus in Little Rock, Arkansas. The clinic was cofounded by Lee Lee Doyle, Ph.D., who is now professor of obstetrics/gynecology at UAMS, and Betty Rouse, R.N., M.N.Sc., who is a clinical associate professor at UAMS, College of Nursing. The outcomes measured were nutritional status as measured by maternal weight gain, infant birth weight, gestational age and Apgar scores. Referrals to appropriate agencies during pregnancy were also reviewed. Analysis of the data revealed that 31% of clients received documented nutritional counseling, 60.2% of the babies were healthy (88% term and 87% appropriate for gestational age), and documented referrals (i.e. WIC, AFDC, Medicaid, etc.) were made in 32% of the cases. Conclusions were that both mothers and infants had positive outcomes. Documentation of referrals needs to be improved or rationale stated for non-referral.

    An adolescent with a chronic condition must prepare for transition from the pediatric to the adult health care system. Ideally, transition is a purposeful and coordinated process between the two systems. We sought to evaluate a pediatric rheumatology transition clinic from the perspective of the young adults who attended the clinic. Young adults who attended the IWK Health Centre Pediatric Rheumatology Transition Clinic in Halifax, Nova Scotia, Canada were asked to complete a mail questionnaire. In this clinic an adult rheumatologist joins the pediatric team for the patient's visit. Subjects rated satisfaction with the clinic and how completely a number of items were addressed (e.g. knowledge about disease, self-management, adolescent issues) on a 10 cm visual analog scale (higher scores reflecting more favourable assessment). Compliance with follow-up post-transfer to adult care was assessed by self-report and a chart review. Data were summarized descriptively. The response rate was 34% (51/151). The mean age of respondents was 22 years with the majority diagnosed with juvenile idiopathic arthritis. Most patients were transferred to adult care between the ages of 17 and 20 years. The mean overall satisfaction score with the transition clinic was 7.3 ± 2.6. There was significant variability regarding how well individual transition-related items were perceived to have been addressed, with an overall mean of 6.1 ± 3.2. Items which received a majority of scores of > 7 included learning about side effects of medications, learning to live with their disease, confidence in disease management, and control of disease at transfer. Items rated as <5 by a third of respondents included addressing teen issues (smoking, alcohol, sexual health) and learning about new developments related to their condition. 74% of patients reported regular appointments with adult rheumatology. Most young adults reported overall satisfaction with the transition clinic, however their

    Picture archiving and communication systems (PACS) are now clinically available in limited radiologic applications. The benefits, acceptability, and reliablity of these systems have thus far been mainly speculative and anecdotal. This paper discusses the evaluation of a PACS module implemented in the pediatric radiology section of a 700-bed teaching hospital. The PACS manages all pediatric inpatient images including conventional x-rays and contrast studies (obtained with a computed radiography system), magnetic resonance images, and relevant ultrasound images. A six-monitor workstation is available for image review.

    Vocal fold paralysis is regarded as a sign of other pathologic findings until investigation has proven that there is no lesion to explain the paralysis. We have outlined a cost-effective and time- and labor-efficient method for the clinical evaluation of vocal fold paralysis, including a focused history; vocal capability assessment to find deficits in the function of palate,pharynx, and larynx: and, finally, an intense examination under topical anesthesia to demonstrate these deficits. In essence, it is the endoscopic version of a radiographic study from the skull base through the aortic arch. This method is streamlined as compared with prior protocols for evaluation of vocal fold paralysis, because it directs the necessary further workup according to the likely site of the lesion as indicated by the extended physical examination and can be conducted entirely in the physician's office. Radiographic workup should include CT of the skull base through the upper mediastinum if solely a recurrent nerve paralysis is present; it should include MRI of the skull base if high vagal signs and symptoms are present. If MRI is negative, CT may also be needed for complete evaluation. Neurologic signs that are not all ipsilateral require MRI of the brain and consultation with a neurologist. Esophageal obstruction combined with vocal fold paralysis mandates evaluation via esophagoscopy or an esophagram.

    BACKGROUND The purpose of this study was to evaluate the characteristics, management, and outcomes of disc battery ingestion in children. METHODS We reviewed the medical records of children admitted to Mofid Children's Hospital due to disc battery ingestion from January 2006 to January 2010. Clear history, clinical symptoms and results of imaging studies revealed diagnosis of disc battery ingestion in suspected patients. The clinical data reviewed included age, gender, clinical manifestation, radiologic findings, location of disc battery, duration of ingestion, endoscopic results and surgical treatment. RESULTS We found 22 cases (11 males and 11 females) of disc battery ingestion with a mean age of 4.3 years (range: 9 months to 12 years). Common symptoms were vomiting, cough, dysphagia, and dyspnea. The mean duration of ingestion was 2.7 days (4 hours to 1.5 months). A total of 19 patients had histories of disc battery ingestion, but three cases referred with the above symptoms, and the batteries were accidentally found by x-ray. Only three cases had batteries impacted in the esophagus. Twelve batteries were removed endoscopically, 6 batteries spontaneously passed through the gastrointestinal (GI) tract within 5 to 7 days, and 4 patients underwent surgery due to complications: 3 due to tracheo-esophageal fistula (TEF) and 1 due to intestinal perforation. There was no mortality in our study. CONCLUSION Most cases of disc battery ingestion run uneventful courses, but some may be complicated. If the battery lodges in the esophagus, emergency endoscopic management is necessary. However, once in the stomach, it will usually pass through the GI tract.

    The purpose of the study was to evaluate the clinical behavior of ceramic class-II inlays (Dicor) in the first 2 years after placement. As a reference, a similar number of dental amalgam restorations were followed up during the same period. Twenty-five inlays and 25 dental amalgams were placed on premolars and first molars of 20 and 19 patients (15-19 years old), respectively. The inlay preparations were made in accordance with the manufacturer's recommendations, and the inlays were produced by a licensed Dicor laboratory. The inlays were luted, using a glass ionomer cement. The dental amalgam preparations were made using standard class-II preparation techniques and filled with ANA 2000. The inlays were evaluated after 6, 12, and 24 months, and the dental amalgam restorations after 24 months, using the criteria suggested by Ryge. In addition, the 24-month examination included proximal recording of dental plaque and gingivitis. With the exception of two inlays that fractured during the observation period, all ceramic inlays showed excellent ratings for anatomic form, marginal discoloration, and marginal caries at all examinations. Two inlays showed minor marginal defects but were classified within the range of acceptance with no need for replacement. The two fractured inlays were replacements of earlier fractured dental amalgams. The clinical behavior of the dental amalgam restorations was in most respects similar to that of the ceramic inlays. Unlike the inlays, however, no dental amalgams fractured during the observation period.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background The cost of genomic information has fallen steeply but the path to clinical translation of risk estimates for common variants found in genome wide association studies remains unclear. Since the speed and cost of sequencing complete genomes is rapidly declining, more comprehensive means of analyzing these data in concert with rare variants for genetic risk assessment and individualisation of therapy are required. Here, we present the first integrated analysis of a complete human genome in a clinical context. Methods An individual with a family history of vascular disease and early sudden death was evaluated. Clinical assessment included risk prediction for coronary artery disease, screening for causes of sudden cardiac death, and genetic counselling. Genetic analysis included the development of novel methods for the integration of whole genome sequence data including 2.6 million single nucleotide polymorphisms and 752 copy number variations. The algorithm focused on predicting genetic risk of genes associated with known Mendelian disease, recognised drug responses, and pathogenicity for novel variants. In addition, since integration of risk ratios derived from case control studies is challenging, we estimated posterior probabilities from age and sex appropriate prior probability and likelihood ratios derived for each genotype. In addition, we developed a visualisation approach to account for gene-environment interactions and conditionally dependent risks. Findings We found increased genetic risk for myocardial infarction, type II diabetes and certain cancers. Rare variants in LPA are consistent with the family history of coronary artery disease. Pharmacogenomic analysis suggested a positive response to lipid lowering therapy, likely clopidogrel resistance, and a low initial dosing requirement for warfarin. Many variants of uncertain significance were reported. Interpretation Although challenges remain, our results suggest that whole genome sequencing can

    In the revised Danish medical specialist training increased focus has been placed on competences which are hard to evaluate such as communication skills. Mini-CEX seems promising as an evaluation tool. Our aim was to test: 1) whether mini-CEX was useable in the evaluation of communicative and cooperative skills and 2) whether mini-CEX would provide reproducible data. Twenty-one residents were evaluated by mini-CEX by trained observers. Seventeen residents had at least two observations within a short period of time and these data were used to estimate the mini-CEX reproducibility. In addition to the residents, the nurses who assisted them in the outpatient clinic answered a questionnaire regarding the mini-CEX satisfaction. Observations had a median duration of 20 minutes (10-60 minutes) and the overall median duration of feedback was 15 minutes (5-60 minutes). Time used for feedback was halved from the first to the following feedback sessions. No significant clinical differences were observed between the scorings performed by the residents themselves and the observers, or the nurses of the outpatient clinic and the observers. In general, the residents were satisfied with the mini-CEX evaluations. The mini-CEX is a promising tool for the evaluation of communicative and cooperative skills.

    The Algerian Current (AC) is unstable and generates mesoscale meanders and eddies. Only anticyclonic eddies can develop and reach diameters over 200 km with vertical extents down to the bottom (˜3000 m). Algerian Eddies (AEs) first propagate eastward along the Algerian slope at few kilometers per day. In the vicinity of the Channel of Sardinia, a few AEs detach from the Algerian slope and propagate along the Sardinian one. It was hypothesized that AEs then followed a counter-clockwise circuit in the eastern part of the basin. Maximum recorded lifetimes were known to exceed 9 months. Within the framework of the 1-year Eddies and Leddies Interdisciplinary Study off Algeria (ELISA) experiment (1997-1998), we exhaustively tracked two AEs, using mainly an ˜3-year time series of NOAA/AVHRR satellite images. We show that AEs lifetimes can near 3 years, exceeding 33 months at least. We also confirm the long-lived AEs preferential circuit in the eastern part of the Algerian Basin, and specify that it may include several loops (at least three).

    A double-masked, individually randomized Phase 3 clinical trial to assess the efficacy, safety and immunogenicity of the pentavalent rotavirus vaccine (PRV), RotaTeq™, was conducted in rural Matlab, Bangladesh (NCT00362648). A total of 1136 infants were enrolled and randomized to receive either vaccine or placebo in a 1:1 ratio administered with the standard EPI vaccines at a mean age of approximately 8, 12, and 16 weeks. Weight was collected at four time points (study vaccine doses 1, 2, and 3, and a close-out visit in March 2009 at 15-26 months of age), and birth weight was retrospectively collected from information contained on the mother's health card when available. Approximately one year following trial completion a separate study was conducted to collect anthropometry measurements, including weight and height. These measurements were linked with Phase 3 trial data and a post hoc analysis was conducted to assess the effects of rotavirus vaccination on malnutrition among enrolled children who could be located when they were between 27 and 38 months old. Among the 1033 (91%) children located, and measured, for this analysis height-for-age and weight-for-height Z scores were calculated and compared between vaccine and placebo recipients at the anthropometry follow-up 1-year post-trial, and weight-for-age Z scores were calculated at four trial time points in addition to the anthropometry follow-up. The data indicated that there was no effect of rotavirus vaccination on malnutrition in this population at any of the measured time points. PRV, estimated to have about 43% efficacy against severe rotavirus gastroenteritis in this population, may not reduce the overall burden of diarrheal illness sufficiently among all vaccinees to appreciably measure impact on growth compared with non-vaccinees. Regardless of the impact on malnutrition indicators, rotavirus vaccines are an important intervention for reducing morbidity and mortality in children in developing

    To evaluate the use of a single Astra Tech implant to support a two-unit cantilever fixed dental prosthesis. Twenty-nine subjects with an edentulous space (at least equivalent to two bicuspid units) in the premolar/molar segments of the maxilla or mandible with opposing natural teeth or a fixed/removable prosthesis were treated. They were provided with either a 4 or 5.0 mm diameter fixture MT OsseoSpeed. Prostheses were constructed using a cast-to abutment as a one-piece unit with porcelain fused to precious metal to allow direct screw retention. Subjects expressed a high satisfaction with treatment, including appearance and function. The most important complication was abutment screw loosening. It occurred as a single episode in four subjects and in another six subjects the loosening was recurrent. Bone levels were stable and there were no significant differences in radiographic bone height between cantilever and non-cantilever sides of the implant at any time point. Single implants can be successfully used to support two-unit cantilever FDPs in the premolar region. A common factor could not be identified in relation to abutment screw loosening. © 2011 John Wiley & Sons A/S.

    Terconazole is the first of a new class of antifungal agents, the triazoles. The results of numerous European studies have demonstrated the efficacy and safety of this agent in both cream and suppository form in the treatment of vulvovaginal candidiasis. Recently, results of short- and long-term analyses in the United States confirmed the efficacy and safety of 0.4% terconazole cream and 80-mg terconazole suppositories. In short-term evaluations (eight to ten days after therapy), 0.4% terconazole cream was as effective as 2.0% miconazole nitrate cream and significantly superior microbiologically in one study. The clinical cure rates with terconazole cream ranged from 87.3% to 95.5% and the microbiologic cure rates, from 76.9% to 91.1%. Thirty- to 35-day microbiologic relapse rates with terconazole cream ranged from 10.4% to 22.2%. In the short-term evaluations of vaginal suppositories the cure rates of 80-mg terconazole suppositories for three days were comparable to those of 100-mg miconazole nitrate suppositories for seven days. The clinical cure rates with 80-mg terconazole suppositories ranged from 90.0% to 92.2% and the microbiologic cure rates, from 80.4% to 85.0%. The 30- to 35-day microbiologic relapse rates of the 80-mg terconazole suppositories ranged from 20.0% to 28.1%. Terconazole cream and suppositories demonstrated an excellent safety profile in all the studies; no life-threatening side effects occurred with any of the regimens. The frequency of common side effects was similar with terconazole and miconazole nitrate formulations.

    Objective: To describe the history and physical examination of the athlete's shoulder. Background: The complex, highly mobile shoulder joint is very susceptible to athletic injury. A comprehensive history and physical examination lay the groundwork for accurate decision making about the nature of the injury and the appropriate treatment plan. Description: In taking the history,inquire about the patient's lifestyle (dominant hand, occupation, sports, activity level) and then focus on the specific complaint. Ask about the location, quality, and nature of the pain and activities that provoke the pain. If stiffness is a factor, a review of systems and the patient's past medical history are important. Discuss any previously undertaken interventions and their effects. The physical examination consists of inspection, range of motion, palpation, manual muscle testing, and provocative tests. Clinical Advantages: Once the clinical evaluation has been completed, the nature of the injury will, in most cases, be apparent. If necessary, appropriate diagnostic tests are ordered, and then a treatment plan tailored to the athlete and the injury is instituted. ImagesFigure 1.Figure 2.Figure 3.Figure 4.Figure 5.Figure 6.

    Objective: The research sought to evaluate whether providing personalized information services by libraries can improve satisfaction with information services for specific types of patients. Methods: Adult breast cancer (BrCa) clinic patients and mothers of inpatient neonatal intensive care unit (NICU) patients were randomized to receive routine information services (control) or an IRx intervention. Results: The BrCa trial randomized 211 patients and the NICU trial, 88 mothers. The BrCa trial showed no statistically significant differences in satisfaction ratings between the treatment and control groups. The IRx group in the NICU trial reported higher satisfaction than the control group regarding information received about diagnosis, treatments, respiratory tradeoffs, and medication tradeoffs. BrCa patients posed questions to librarians more frequently than did NICU mothers, and a higher percentage reported using the website. Questions asked of the librarians by BrCa patients were predominantly clinical and focused on the areas of treatment and side effects. Conclusions: Study results provide some evidence to support further efforts to both implement information prescription projects in selected settings and to conduct additional research on the costs and benefits of services.

    The objective of this study was to describe the outcomes of an infant oral health programme 3 years after implementation, a programme focused on health education for parents and caries prevention methods for children in a baby clinic. A retrospective cohort study was carried out. The setting was the Infant Oral Health Programme developed at the baby clinic of the State Department of Health, Goiânia-GO, Brazil. The sample comprised 100 children who entered the programme from birth to 12 months and were followed for 2 to 3 years. Variables investigated were caries experience, caries risk, and children's behaviour in the dental clinic. The number of children with caries experience was 1 at the initial visit and 8 after the follow-up. There was a dramatic decrease in the number of children in the high risk group, from 51% at the initial visit to only 1% after 2 to 3 years. Children's behaviour in the dental clinic was according to their psychological development. It was concluded that the Infant Oral Health Programme in Goiânia showed positive outcomes after 3 years of establishment. Further investigations should evaluate the cost-benefit, as well as the effectiveness of the procedures used in the programme.

  3. Diagnosis and clinical evaluation of iron overload.

    PubMed

    Kaltwasser, J P; Werner, E

    1989-04-01

    Diagnostic evaluation of the various forms of iron overload requires information about the total amount and distribution of iron stores. Direct information on the quantity of storage iron can be obtained only by its mobilization in response to repeated phlebotomy or after dilution of a labelled iron test dose in the total body iron pool. Both approaches are cumbersome and time-consuming and are suitable only for research purposes. Detailed information on the amount and distribution of tissue iron in iron overload can be obtained from biopsy specimens of the major iron storage organs such as the liver and bone marrow. However, the invasive nature of these procedures limits their clinical usefulness. Indirect measures, such as serum iron concentration, TIBC saturation, serum ferritin, chelate-induced urinary iron excretion or intestinal iron absorption, and ferrokinetic measurements may provide useful information on the amount of total body iron reserve. However, they all have important limitations in their diagnostic use for evaluating iron overload. The most suitable indirect storage iron index among these methods is the ferritin assay, which has a well established place in the diagnosis of iron overload and monitoring of the effect of therapy. Recent developments in physical methods such as CT, SQUID and NMR have significantly improved the applicability of these techniques for non-invasive measurement of liver iron. It is expected that quantitative measurement of hepatic iron stores will soon be integrated into the diagnostic procedures available by imaging techniques such as CT and NMR. In combination with screening parameters such as serum ferritin and TIBC saturation these new but expensive diagnostic tools may simplify and shorten the diagnostic process and may also be useful for monitoring the treatment of iron overload by phlebotomy or chelating drugs.

    OBJECTIVE An artificial pancreas (AP) that automatically regulates blood glucose would greatly improve the lives of individuals with diabetes. Such a device would prevent hypo- and hyperglycemia along with associated long- and short-term complications as well as ease some of the day-to-day burden of frequent blood glucose measurements and insulin administration. RESEARCH DESIGN AND METHODS We conducted a pilot clinical trial evaluating an individualized, fully automated AP using commercial devices. Two trials (n = 22, nsubjects = 17) were conducted using a multiparametric formulation of model predictive control and an insulin-on-board algorithm such that the control algorithm, or “brain,” can be embedded on a chip as part of a future mobile device. The protocol evaluated the control algorithm for three main challenges: 1) normalizing glycemia from various initial glucose levels, 2) maintaining euglycemia, and 3) overcoming an unannounced meal of 30 ± 5 g carbohydrates. RESULTS Initial glucose values ranged from 84–251 mg/dL. Blood glucose was kept in the near-normal range (80–180 mg/dL) for an average of 70% of the trial time. The low and high blood glucose indices were 0.34 and 5.1, respectively. CONCLUSIONS These encouraging short-term results reveal the ability of a control algorithm tailored to an individual’s glucose characteristics to successfully regulate glycemia, even when faced with unannounced meals or initial hyperglycemia. To our knowledge, this represents the first truly fully automated multiparametric model predictive control algorithm with insulin-on-board that does not rely on user intervention to regulate blood glucose in individuals with type 1 diabetes.

    Clinical information models are formal specifications for representing the structure and semantics of the clinical content within electronic health record systems. This research aims to define, test, and validate evaluation metrics for software tools designed to support the processes associated with the definition, management, and implementation of these models. The proposed framework builds on previous research that focused on obtaining agreement on the essential requirements in this area. A set of 50 conformance criteria were defined based on the 20 functional requirements agreed by that consensus and applied to evaluate the currently available tools. Of the 11 initiative developing tools for clinical information modeling identified, 9 were evaluated according to their performance on the evaluation metrics. Results show that functionalities related to management of data types, specifications, metadata, and terminology or ontology bindings have a good level of adoption. Improvements can be made in other areas focused on information modeling and associated processes. Other criteria related to displaying semantic relationships between concepts and communication with terminology servers had low levels of adoption. The proposed evaluation metrics were successfully tested and validated against a representative sample of existing tools. The results identify the need to improve tool support for information modeling and software development processes, especially in those areas related to governance, clinician involvement, and optimizing the technical validation of testing processes. This research confirmed the potential of these evaluation metrics to support decision makers in identifying the most appropriate tool for their organization.

    The change in the concepts of cavity preparation and the development of reliable adhesive materials lead to the development of alternative methods of caries removal. Chemo-mechanical caries removal (CMCR) involves the chemical softening of carious dentin, followed by its removal with gentle excavation. The present study was conducted to evaluate clinically the efficiency of caries removal using a new chemo-mechanical agent (Papacarie) compared to the conventional drilling method including the need for local anesthesia, the need for drill, duration of the treatment and the pain reaction. This study was split mouth design. The study was performed on thirty seven bilateral open carious lesions. They were divided into two equal groups according to method of caries removal. In Group I, caries was removed using the Papacarie system and in Group II, caries was removed with the conventional drill. The results showed that the Papacarie was as efficient as the drill in caries removal from open carious lesions with no significant difference in the operating time. The new CMCR agent also reduced significantly the need for local anesthesia and the use of drill. In addition, Papacarie was also more comfortable than the traditional rotatory instruments. It was concluded that Papacarie could be an effective caries removal method to treat children, particularly those who present with early childhood caries or management problems.

    One hundred ninety-two subjects completed a clinical trial to determine the effects of seven dentifrice formulations on calculus inhibition. The double-blind study involved a ten-day control phase and a ten-day experimental phase. For the control phase, subjects were evaluated for calculus present, received a prophylaxis and had pre-weighed mylar strips attached to the lingual surfaces of the mandibular incisors to harvest mineral deposits. Subjects were then assigned the placebo dentifrice for unsupervised twice-daily use and were required to report once a day for a supervised mouthrinse using a 1:3 dilution of the dentrifice. The experimental phase was identical except that subjects were allocated the experimental dentifices using a stratified random assignment based on age, gender and the initial presence of calculus. Simple linear regression analyses of the dry and ash log weights obtained from the strips were performed. The results showed no statistically significant differences among the test products; however, two formulations containing zinc citrate showed some calculus inhibition-potential suggesting that further research and development of such products may be warranted.

    Oxypertine, a new anxiolytic drug related to the indolylazine compounds, was evaluated in a group of 30 patients, the majority with severe anxiety (acute or chronic) : in some cases depression was associated. The study was performed in the Psychiatric Department at the Centro Femenil de Rehabilitación Social, in Mexico City. A special feature of this study was that patients were confined for a legal process and consequently with restricted liberty. All were females between 19 to 44 years old, with an average age of 32.05 years. The methodology applied in this case was a modified double blind randomized procedure, using different color capsules with placebo or the active drug (yellow oxypertine and blue placebo). Patients received a 10 mg capsule every 12 hours (20 mg daily). The clinical measurement of anxiety was performed using the Visual Anxiety Scale (Murphy), evaluating each of its 11 parameters. The intensity was qualified from 0 to 3; at the end of each consultation a global assessment was made. Most of the patients were interviewed in five occasions during the treatment period. For each of the nine patients receiving during 4 weeks only oxypertine capsules (group I), the scores of the parameters of the scale were added, observing the following results: in seven excellent respond, fair in one and one abandoned the study since the beginning. In eight of the patients who received placebo (group II) also for a 4 weeks period, results were evaluated as follows: five excellent one good and two poor. It can be observed that both groups gave a similar final score at the end of the study, meaning that no significant benefits were obtained between the active drug and the placebo, in spite that anxiety decreased in most of them. In group III, seven cases initiated with placebo and after 2 weeks the capsule had to be changed to oxypertine due to stablization or increase in the anxiety. Results were excellent in three, good in two, poor in one and another case

    The aim of the study was to compare the clinical performance, quantitative and qualitative wear patterns of conventional hybrid (Tetric Ceram), micro-filled hybrid (Gradia Direct Posterior) and nano-hybrid (Tetric EvoCeram, TEC) posterior composite restorations in a 3-year randomised clinical trial. Sixteen Tetric Ceram, 17 TEC and 16 Gradia Direct Posterior restorations were placed in human molars and evaluated at baseline, 6, 12, 24 and 36 months of clinical service according to US Public Health Service criteria. The gypsum replicas at each recall were used for 3D laser scanning to quantify wear, and the epoxy resin replicas were observed under scanning electron microscope to study the qualitative wear patterns. After 3 years of clinical service, the three hybrid restorative materials performed clinically well in posterior cavities. Within the observation period, the nano-hybrid and micro-hybrid restorations evolved better in polishability with improved surface gloss retention than the conventional hybrid counterpart. The three hybrid composites showed enamel-like vertical wear and cavity-size dependant volume loss magnitude. Qualitatively, while the micro-filled and nano-hybrid composite restorations exhibited signs of fatigue similar to the conventional hybrid composite restorations at heavy occlusal contact area, their light occlusal contact areas showed less surface pitting after 3 years of clinical service.

    Current clinical evaluation of literature quality has various ways. Most of them lay special emphasis on the evaluation of the design quality, but the evaluation of the implementation process quality is not perfect. Especially data management is not fully emphasized during the enforcement of clinical trials. Data from clinical research were bases for evaluating clinical findings. Although strict specifications and requirements for data management might be strictly written clearly in research protocols, they were not embodied in current clinical research evidence evaluation system. Data management is an important part of implementing the whole clinical trial process, which is a comprehensive reflection of data collecting, logging, sorting, and managing. Its objective is to obtain high quality research data for statistical analysis, thereby coming to a true and reliable conclusion. In order to overall evaluating clinical design and implement, we suggest that present quality evaluation indicators of clinical trails should be completed, and add data management quality evaluation during the whole implement process. Data management plans, standards and requirements for data checking, and management regulations for disobeying data and exception data should be added in quality evaluation indicators for clinical research evidence. The effect of data management quality on clinical research evidence evaluation should be emphasized.

    A 3-year-old patient was referred to the oral and maxillofacial department with a fracture of the orbital floor. Due to the lack of clinical symptoms, a conservative approach was chosen. After 3 weeks, an enophthalmos developed. The orbital floor reconstruction was successfully performed through a transconjunctival approach. This case highlights the rarity of pure blowout fractures in young children. The specific presentation and diagnostics of orbital floor fractures in children and the related surgical planning and intervention are discussed. PMID:24436749

    MR urography (MRU) is an image diagnostic method which provides us with the image of urinary retention under non-invasive procedures. This time, MRU was conducted in the patients who were suspected to have urinary passage disorder, and its clinical usefulness was compared with that of drip infusion pyelography (DIP) or retrograde pyelography (RP). The study was conducted in 65 patients who were suspected to have obstructive uropathy based on the ultrasonographic findings. MRU was conducted by means of fast SE method to obtain heavy T2-weighted image. The urogram was reconstructed by means of MIP (maximum intensity projection) method. As imaging examinations, MRU, DIP and RP were conducted respectively in 65, 47 and 27 patients. Evaluation of clinical usefulness of MRU and its indications were conducted with respect to (1) the degree of urinary retention which is identifiable by MRU by (2) comparing performance of MRU and that of other image diagnostic methods based on the scores given to MRU and other methods according to the following scale: Urinary tract is not identifiable 0 point Urinary tract is slightly identifiable 1 point The obstructive region is almost clearly identifiable 2 points The lesion causative for obstruction is identifiable 3 points. 1) Mild urinary retention for which overall image of urinary tract was barely identifiable by DIP was identifiable by MRU. 2) In the comparison between DIP and MRU, 24 patients whose urinary tracts were totally unidentifiable by DIP was given was 2.4 points in the average for the identifiability of urinary retention by MRU. Conversely, only poor images were attainable by MRU in the patients whose urinary flow was clearly seen in DIP. The patients whose urinary flow was clearly seen in RP was give 1.9 points in the average for the identifiability of urinary retention by MRU, indicating that relatively poor images were attainable by MRU in those patients.

    Reflective journaling is a strategy used often in clinical education to gain insight into students' clinical thinking; however, studies indicate that students may benefit from guided reflections. Numerous tools have been used to structure student reflection with varying results. This article describes the outcomes from using the Guide for Reflection based on Tanner's Clinical Judgment Model. The Lasater Clinical Judgment Rubric, created from the Model, is used to evaluate development of clinical judgment and provides language to communicate about clinical thinking with students. Senior immersion course competencies, also developed with language from Tanner's Clinical Judgment Model,offer a comprehensive package that fosters students' clinical judgment development, faculty-student communication about clinical judgment, and evaluation of students' clinical thinking.

    Objective This study compares the results of an objective structured clinical examination (OSCE) between 2 groups of students before an internship and after 6 months of clinical practice in an internship. Methods Seventy-two students participated, with 36 students in each cohort. The OSCEs were performed in the simulation laboratory before the participants' clinical practice internship and after 6 months of the internship. Students were tested in 9 stations for clinical skills and knowledge. The same procedures were repeated for both cohorts. The t test was used for unpaired parametric samples and Fisher's exact test was used for comparison of proportions. Results There was no difference in the mean final score between the 2 groups (p = .34 for test 1; p = .08 for test 2). The performance of the students in group 1 was not significantly different when performed before and after 6 months of clinical practice, but in group 2 there was a significant decrease in the average score after 6 months of clinical practice. Conclusions There was no difference in the cumulative average score for the 2 groups before and after 6 months of clinical practice in the internship. There were differences within the cohorts, however, with a significant decrease in the average score in group 2. Issues pertaining to test standardization and student motivation for test 2 may have influenced the scores. PMID:25588200

    This prospective 3-year follow-up clinical study evaluated the survival and success rates of 3DP/AM titanium dental implants to support single implant-supported restorations. After 3 years of loading, clinical, radiographic, and prosthetic parameters were assessed; the implant survival and the implant-crown success were evaluated. Eighty-two patients (44 males, 38 females; age range 26–67 years) were enrolled in the present study. A total of 110 3DP/AM titanium dental implants (65 maxilla, 45 mandible) were installed: 75 in healed alveolar ridges and 35 in postextraction sockets. The prosthetic restorations included 110 single crowns (SCs). After 3 years of loading, six implants failed, for an overall implant survival rate of 94.5%; among the 104 surviving implant-supported restorations, 6 showed complications and were therefore considered unsuccessful, for an implant-crown success of 94.3%. The mean distance between the implant shoulder and the first visible bone-implant contact was 0.75 mm (±0.32) and 0.89 (±0.45) after 1 and 3 years of loading, respectively. 3DP/AM titanium dental implants seem to represent a successful clinical option for the rehabilitation of single-tooth gaps in both jaws, at least until 3-year period. Further, long-term clinical studies are needed to confirm the present results. PMID:27313616

    In the past century, significant advances have been made in understanding the clinical features of acoustic neuromas. Furthermore, rapid technological advances have led to the development of sensitive, rapid, and relatively noninvasive diagnostic modalities, which has allowed for earlier discovery of acoustic neuromas and has reduced the average tumor size at time of diagnosis. The ultimate result has been improved clinical outcomes after surgery and radiotherapy.

    2015-01-01

    Parkinson's disease harbours many different tremors that differ in distribution, frequency, and context in which they occur. A good clinical tremor assessment is important for weighing up possible differential diagnoses of Parkinson's disease, but also to measure the severity of the tremor as a basis for further tailored treatment. This can be challenging, because Parkinson's tremor amplitude is typically very variable and context-dependent. Here, we outline how we investigate Parkinson's tremor in the clinic. We describe a simple set of clinical tasks that can be used to constrain tremor variability (cognitive and motor co-activation, several specific limb postures). This may help to adequately characterize the tremor(s) occurring in a patient with Parkinson's disease.

    Bariatric surgery is increasingly considered for the treatment of adolescents with severe obesity, but few prospective adolescent-specific studies examining the efficacy and safety of weight-loss surgery are available to support clinical decision making. We prospectively enrolled 242 adolescents undergoing weight-loss surgery at five U.S. centers. Patients undergoing Roux-en-Y gastric bypass (161 participants) or sleeve gastrectomy (67) were included in the analysis. Changes in body weight, coexisting conditions, cardiometabolic risk factors, and weight-related quality of life and postoperative complications were evaluated through 3 years after the procedure. The mean (±SD) baseline age of the participants was 17±1.6 years, and the mean body-mass index (the weight in kilograms divided by the square of the height in meters) was 53; 75% of the participants were female, and 72% were white. At 3 years after the procedure, the mean weight had decreased by 27% (95% confidence interval [CI], 25 to 29) in the total cohort, by 28% (95% CI, 25 to 30) among participants who underwent gastric bypass, and by 26% (95% CI, 22 to 30) among those who underwent sleeve gastrectomy. By 3 years after the procedure, remission of type 2 diabetes occurred in 95% (95% CI, 85 to 100) of participants who had had the condition at baseline, remission of abnormal kidney function occurred in 86% (95% CI, 72 to 100), remission of prediabetes in 76% (95% CI, 56 to 97), remission of elevated blood pressure in 74% (95% CI, 64 to 84), and remission of dyslipidemia in 66% (95% CI, 57 to 74). Weight-related quality of life also improved significantly. However, at 3 years after the bariatric procedure, hypoferritinemia was found in 57% (95% CI, 50 to 65) of the participants, and 13% (95% CI, 9 to 18) of the participants had undergone one or more additional intraabdominal procedures.

    Long-term practice-based clinical evaluations of various contemporary ceramic crown restorations from multiple practitioners are limited. The aims of this study were to evaluate the clinical performance of ceramic single crowns and to identify factors that influence their clinical performance. Ceramic single crowns that had been placed at the Mayo Clinic and in function since 2005 were identified and included in the study. The restorations were examined clinically, radiographically, and with photographs. Modified United States Public Health Services criteria were used for the clinical evaluation. The ceramic systems evaluated were bilayer and monolayer. Fifty-nine patients (41 women, 18 men) with 226 single teeth and implants restored with single ceramic crowns were identified. The mean duration from insertion date to study examination date was 6.1 years. Thirteen restorations (6%) were replaced at a mean 3.3 years after insertion date (range, 0.1-6.1 years). Estimated replacement-free survival rates (95% confidence interval [CI]; number of teeth/implants still at risk) at 5 years after insertion date were 95.1% (95% CI, 92.2-98.1; 153) and at 10 years were 92.8% (95% CI, 89.1-96.8; 8). The most common reason for replacement was fracture to the core of posterior layered ceramic crowns. The most commonly used luting agent was resin-modified ionomer cement. Most restorations exhibited clinically acceptable marginal integrity, shade, no caries recurrence, and no periapical pathology. The clinical performance of ceramic single crowns at 5 and 10 years supports their application in all areas of the mouth. With the majority of fractures to the core occurring early in the lifetime of layered ceramic posterior crowns, consideration of other monolithic ceramic systems for posterior crowns is advised.

    Purpose: To compare long-term efficacy of cryoplasty therapy versus conventional angioplasty in the treatment of peripheral arterial atherosclerotic stenosis on the basis of our 3-year clinical experience. Materials and Methods: From January 2006 to December 2008, a total of 155 patients with 192 lesions of the femoropopliteal sector were randomized to receive either cryoplasty or conventional balloon angioplasty. The primary study end point was lesion target patency. Follow-up with clinical evaluation of patient's symptoms, ankle-brachial index, and Doppler ultrasound was scheduled at 1, 6, 9, 12, 24, and 36 months. Results: For the cryoplasty group (n = 86), technical immediate success was achieved in 74.4% of lesions. Rate of significant dissection was 13.5% and rate of stent placement of 22%. In the long term, target lesion patency rate at 6 months was 59.4%, with rates of 55.9, 52.6, and 49.1% at 1, 2, and 3 years, respectively. For the conventional angioplasty group (n = 69), the immediate technical success rate was 83.7%. Rate of significant dissection was 19%, and rate of stent placement was 72.9%. Patency rates at 6 months and at 1, 2, and 3 years were 71.5, 61.2, 60, and 56%, respectively. Conclusion: Compared with conventional angioplasty, cryoplasty showed good immediate success rates with lower stent placement rates. During the 3-year follow-up, patency rates tended to equalize between the two modalities.

    An accurate system of identifying and classifying suspected measles cases is critical for the measles surveillance system in the United States. To examine the performance of the clinical case definition in predicting laboratory confirmation of suspected cases of measles, we reviewed 4 studies conducted between 1981 and 1994. A clinical case definition was examined that included a generalized maculopapular rash, fever (>or=38.3 degrees C, if measured), and either a cough, coryza, or conjunctivitis. Serological confirmation of measles was done either by hemagglutination inhibition assay, complement fixation assay, or enzyme immunoassays. The positive predictive value of the clinical case definition decreased from 74% to 1% as incidence decreased from 171 cases/100000 population to 1.3 cases/100000 population. Sensitivity was high, and for the larger studies with the most precise estimates, sensitivity was 76%-88%. The low positive predictive value of the clinical case definition in settings of low incidence demonstrates that serological confirmation is essential to ensure an accurate diagnosis of measles when measles is rare.

    Lack of scientific and confirmed researches and expert knowledge about evaluation systems for clinical governance development in Iran have made studies on different evaluation systems for clinical governance development a necessity. These studies must provide applied strategies to design criteria of implementing clinical governance for hospital's accreditation. This is a descriptive and comparative study on development of clinical governance models all over the world. Data have been gathered by reviewing related articles. Models have been studied in comprehensive review method. The evaluated models of clinical governance development were Australian, NHS, SPOCK and OPTIGOV. The final aspects extracted from these models were Responsiveness, Policies and Strategies, Organizational Structure, Allocating Resources, Education and Occupational Development, Performance Evaluation, External Evaluation, Patient Oriented Approach, Risk Management, Personnel's Participation, Information Technology, Human Resources, Research and Development, Evidence Based Medicine, Clinical Audit, Health Technology Assessment and Quality. These results are applicable for completing the present criteria which evaluating clinical governance application and provide practical framework to evaluate country's hospital on the basis of clinical governance elements.

    By means of repeated, well-supported measurements of clinical dynamic indicators from the Historical, Clinical and Future - 30 (HKT-30) it is possible to monitor behavioural changes on the basis of risks and needs. The addition of extra score parameters allows us to distinguish client-specific risks and needs. In treatment evaluation it is important to visualise changes in these indicators of treatment evaluation because they are the key to the clinical decision-making process that determines further treatment and rehabilitation. To investigate whether HKT-30 indicators can be used to measure and visualise behavioral changes for the purpose of treatment evaluation. A case study is used to illustrate how clinicians at the Forensic Psychiatric Clinic (FPK), De Woenselse Poort, ascertain risks, needs and changes and clarify these factors for the purpose of treatment evaluation and clinical decision-making. Routine treatment evaluation aided by visualised clinical HKT-30 indicators give the treatment team and the client a clearer picture of the behavioral changes for which the forensic treatment was prescribed. This evaluation provides significant starting-points for clinical decision making. Routine treatment evaluation along with a suitably adjusted HKT-30 make behavioural changes visible, render clinical decisions more transparent and provide valuable starting-points for a dialogue with the client about his treatment.

    Background: Tramadol is a synthetic analgesic. Seizures have been reported in patients receiving this drug. In this study we evaluated the correlation between tramadol consumption and seizure occurrence. Methods: Twenty-eight subjects with a history of tramadol consumption and seizure were studied. Electroencephalograms (EEG) were performed in the first 24 hours and again one week later. Subjects were followed up for a mean of 18 months after the initial attack. Results: In the 28 subjects, 26 (92.8%) were males and 2 (7.2%) were females. The mean age of the subjects was 28.4 years. Thirteen patients had abused more than 400 mg/day of tramadol. Sixteen subjects concomitantly used other drugs. The seizures occurred within the first 24 hours of tramadol intake in 25 of the subjects. The first EEG was abnormal in 12 cases, but the second EEG was abnormal in only one case. Neuroimaging of only one subject displayed patchy white matter lesions. Conclusion: In conclusion, the neurotoxicity of tramadol commonly manifests as generalized tonic clonic seizures most frequently within 24 hours after tramadol intake and was more common in subjects concomitantly consuming alcohol, illicit drugs, anti-psychotics, or anti-depressants.

    Posaconazole, a broad-spectrum triazole antifungal agent, is approved for the prevention of invasive aspergillosis and candidiasis in addition to the treatment of oropharyngeal candidiasis. There is evidence of efficacy in the treatment and prevention of rarer, more difficult-to-treat fungal infections. Posaconazole oral suspension solution has shown limitations with respect to fasting state absorption, elevated gastrointestinal pH and increased motility. The newly approved delayed-release oral tablet and intravenous solution formulations provide an attractive treatment option by reducing interpatient variability and providing flexibility in critically ill patients. On the basis of clinical experience and further clinical studies, posaconazole was found to be a valuable pharmaceutical agent for the treatment of life-threatening fungal infections. This review will examine the development history of posaconazole and highlight the most recent advances.

    1992-01-01

    The author looks at the question of psychic change from the viewpoint of difficulties involved in this change, starting with a short historical overview. He discusses 'the difficult patient as a specialist in resisting change' and describes the clinical characteristics of such patients over and above their psychopathological diagnoses. Some specific clinical cases are described to clarify the theoretical ideas. The author then covers the nature of changes best studied within the field of transference and countertransference. Finally, he examines change as a process of change and suggests that qualitative differences exist between psychic functions relating to 'traumas' in narcissistic constraints. These differences are apparent in psychic content. The connexions between interpretation, insight, anxiety and change are described. The nature of the negative therapeutic reaction is discussed. The notion of an underlying deficiency in the development of genuine egoistic resources required to bring about psychic change is examined.

    The anesthesia preoperative evaluation has been developed in recent years in a centralized clinic, that can be visited by the majority of patients, in order to evaluate and obtain patient's consent for anesthesia. In the current article, the organization and structure of such a central anesthesia preoperative evaluation clinic in the Department of Anesthesia, Intensive Care and Pain Medicine at the University Hospital of Muenster, is described. Besides the central preoperative evaluation clinic, 3 clinics are localized in separate buildings and preoperative visits have to be completed in special scenarios on the wards, too. A pharmaceutical evaluation for patient's medication and the patient blood management have been integrated into the anesthesia preoperative evaluation clinic. Processes are explained and current numbers of patients are mentioned. © Georg Thieme Verlag Stuttgart · New York.

    Few studies have investigated the outcomes and process of psychodynamic psychotherapies with children. Among the limited number of studies, some only paid attention to play and verbal production, as they are fundamental aspects in assessing the psychotherapy process. This paper focuses on an empirical investigation of a 3-year, once-a-week psychodynamic psychotherapy carried out with a 3-year-old girl. A process-outcome design was implemented to evaluate play and verbal discourse in in the initial, middle, and final parts of 30 psychotherapy sessions. Repeated measurements of standardized play categories (the Play Category System and the Affect in Play Scale—Preschool version) and verbal discourse (Verbal Production) were analyzed. To increase the clinical validity of the study, data from the assessment phase and vignettes from the sessions were reported to deepen the patient’s picture during the unfolding therapy process. Parent reports before and after the therapy were also included. Empirically measured changes in play and verbal production were fundamental in evaluating the young patient’s psychotherapy process. Verbal production and discourse ability progressively increased and took the place of play, which instead became more symbolic. Developmental issues as well as psychotherapy’s influence on the patient’s change, were discussed in relation to the role of play in enhancing the development of verbal dialog and the expression of the child’s emotions, needs, and desires.

    The aim was to test the null-hypothesis that there is no difference in the cumulative survival rate of retained composite resin (CR) sealants and a high-viscosity glass-ionomer Atraumatic Restorative Treatment (ART) sealant in first permanent molars calculated according to the traditional and the modified retention assessment criteria over a period of 3 years. This cluster-randomized controlled clinical trial consisted of 123 schoolchildren, 6-7-years-old. At baseline, high-caries risk pits and fissures of fully erupted first permanent molars were treated with CR and ART sealants. Evaluations were performed after 0.5, 1, 2 and 3 years. Retention was scored for free-smooth surface and for each of three sections into which the occlusal surface had been divided. The modified criterion differed from the traditional in that it determined an occlusal sealant to be a failure when at least one section contained no visible sealant material. Data were analysed according to the PHREG model with frailty correction, Wald-test, ANOVA and t-test, using the Jackknife procedure. The cumulative survival rates for retained CR and ART sealants in free-smooth and occlusal surfaces for both criteria were not statistically significantly different over the 3 years. A higher percentage of retained CR sealants on occlusal surfaces was observed at longer evaluations. Cumulative survival rates were statistically significantly lower for the modified criterion in comparison to the traditional. The modified retention assessment criterion should be used in future sealant-retention studies.

    Abstract Objective: To compare three potential sources of controlled clinical terminology (READ codes version 3.1, SNOMED International, and Unified Medical Language System (UMLS) version 1.6) relative to attributes of completeness, clinical taxonomy, administrative mapping, term definitions and clarity (duplicate coding rate). Methods: The authors assembled 1929 source concept records from a variety of clinical information taken from four medical centers across the United States. The source data included medical as well as ample nursing terminology. The source records were coded in each scheme by an investigator and checked by the coding scheme owner. The codings were then scored by an independent panel of clinicians for acceptability. Codes were checked for definitions provided with the scheme. Codes for a random sample of source records were analyzed by an investigator for “parent” and “child” codes within the scheme. Parent and child pairs were scored by an independent panel of medical informatics specialists for clinical acceptability. Administrative and billing code mapping from the published scheme were reviewed for all coded records and analyzed by independent reviewers for accuracy. The investigator for each scheme exhaustively searched a sample of coded records for duplications. Results: SNOMED was judged to be significantly more complete in coding the source material than the other schemes (SNOMED* 70%; READ 57%; UMLS 50%; *p <.00001). SNOMED also had a richer clinical taxonomy judged by the number of acceptable first-degree relatives per coded concept (SNOMED* 4.56; UMLS 3.17; READ 2.14, *p <.005). Only the UMLS provided any definitions; these were found for 49% of records which had a coding assignment. READ and UMLS had better administrative mappings (composite score: READ* 40.6%; UMLS* 36.1%; SNOMED 20.7%, *p <. 00001), and SNOMED had substantially more duplications of coding assignments (duplication rate: READ 0%; UMLS 4.2%; SNOMED* 13.9%, *p

    The recognition that inflammatory events in the airways play a key role in the pathogenesis of asthma has led to a relentless search for pharmacological agents which modify these processes. Nedocromil sodium (Tilade) represents one such agent. Nedocromil sodium, when inhaled by patients with asthma (0.05-0.50% nebulized, 0.5-4.0 mg m.d.i.), has been shown to inhibit immediate bronchoconstriction provoked by challenges with allergen (10 studies), exercise (five studies), isocapnic hyperventilation, fog and sulphur dioxide (one study each) and adenosine (two studies). With these challenges, inhibition of bronchoconstriction exhibited dose-dependency up to 4 mg, with nedocromil sodium being up to four times more potent than sodium cromoglycate. When inhaled prior to allergen provocation, nedocromil sodium inhibited the late asthmatic reaction; when taken regularly during the pollen season, it attenuated the allergen-induced increase in non-specific bronchial responsiveness. The efficacy of nedocromil sodium (4 mg q.i.d.) in the treatment of clinical asthma was initially shown in four open studies and subsequently confirmed in nine double-blind, placebo-controlled 4-12 week studies on patients with seasonal and perennial asthma. Further clinical trials (eight studies) identified some difficulty in replacing inhaled corticosteroids with nedocromil sodium, especially if the corticosteroids were reduced rapidly (four studies). However, two studies have shown that nedocromil sodium produced further improvement in asthma symptoms when used in addition to bronchodilators and inhaled corticosteroids. Treatment with nedocromil sodium (4 mg q.i.d.) for up to 52 weeks demonstrated a progressive reduction in bronchodilator usage throughout the whole treatment period. During clinical assessment, nedocromil sodium was well tolerated, side-effects being unpleasant taste, nausea and headache. In most cases the adverse reactions were mild and transient, although in approximately 3% of

    Scleroderma featuring rare connective tissue disease that manifests as skin sclerosis and variable systemic involvement. Two categories of scleroderma are known: systemic sclerosis, characterized by cutaneous sclerosis and visceral involvement and localized scleroderma or morphea which classically presents benign evolution and self-limited, confined to the skin and/or underlying tissue. Recent studies show that the localized form may possibly course with involvement of internal organs and variable morbidity. This study aimed to determine the demographic characteristics, the prevalence of systemic manifestations and laboratory findings, as well as the association with autoimmune diseases, and the evolution of neurological findings, both clinical as brain MRI in patients with scleroderma of the face and its relation with the activity skin. Patients with localized scleroderma with facial involvement were evaluated and underwent neurological examination, magnetic resonance imaging and ophthalmology evaluation. After 3years, the patients were subjected again to MRI. We studied 12 patients with localized scleroderma of the face. Of this total, headache being the most frequent complaint found in 66.7% of patients, 33.3% had neurological changes possibly associated with scleroderma. As for ophthalmologic evaluation, 25% of patients showed abnormalities. The most frequent parenchymal finding was the presence of lesions with hyperintense or hypointense signal in 75% of patients, followed by ventricular asymmetry at 16.7%. Of the patients who had neurological deficits, 75% also had a change to MRI. In all patients, imaging findings after 3years were unchanged. During this interval of 3years, 25% of patients showed signs of activity of scleroderma. Patients with localized scleroderma of the face have a high prevalence of neurological and ophthalmological changes. Based on these findings, we suggest that all cases of localized scleroderma of the face should be thoroughly

    Little is known about the clinical performance of ceramic cantilever fixed dental prostheses on natural teeth. The purpose of this randomized controlled pilot study was to evaluate the clinical performance of ceramic and metal ceramic cantilever fixed dental prostheses (CFDPs) after 3 years of service. Twenty-one participants were randomly allocated to 2 treatment groups. Participants in the ceramic (ZC) group (n=11) each received 1 CFDP made of yttria-stabilized, tetragonal zirconia polycrystal; the others (n=10) were fitted with a metal ceramic (MC) CFDP. All CFDPs were retained by 2 complete crown abutments and replaced 1 tooth. The clinical target variables were survival, incidence of complications, probing pocket depth (PPD), probing attachment level (PAL), plaque index (PI), gingival index (GI), and esthetic performance as rated by the participants. The United States Public Health Service (USPHS) criteria were used to evaluate chipping, retention, color, marginal integrity, and secondary caries. Descriptive statistics and nonparametric analyses were applied to the target variables in the 2 groups. The esthetic performance of the CFDPs was also visualized by using a pyramid comparison. The overall survival of the CFDPs was 100% in both groups. During the 3-year study, 6 clinically relevant complications requiring aftercare were observed among 5 participants (4 in the ZC group and 2 in the MC group). Changes in the PI, GI, PPD, and PAL of the abutment teeth were similar for both groups (P>.05). The participants regarded the esthetic performance of ZC-CFDPs and MC-CFDPs as satisfactory. Within the 3-year observation period, the clinical performance of MC-FDPs and ZC-FDPs was acceptable. More extensive research with larger sample sizes is encouraged, however, to confirm the evaluation of the survival of Y-TZP hand-veneered cantilever FPDs.

    Terconazole is a new topical antifungal agent that differs structurally and functionally from the imidazoles. European clinical trials were conducted to determine (1) the lowest effective dose for a given treatment period, (2) which formulation should be tested further, and (3) how terconazole compares with other topical antifungal agents in terms of safety and efficacy. The results of dose-response studies demonstrated that 80- and 240-mg suppositories and 0.4% cream were the most effective formulations. Data from multicenter studies of pregnant and nonpregnant women in Belgium and Luxembourg indicate that the efficacy of terconazole cream is superior to that of miconazole nitrate cream and clotrimazole cream. Terconazole cream is also more effective than clotrimazole cream in terms of lower relapse rates.

    We have examined two types of liquid crystal thermometers (LCT) designed for clinical use: one designed to measure skin surface temperature (LCTS) and the other had its calibration shifted by 1.9 degrees C to read a "core" temperature (LCTC). In laboratory tests with LCT on a glass beaker, there were highly significant correlations between temperatures measured by thermocouples, LCTS (r = 0.99) and LCTC (r = 0.99). In five patients undergoing cooling and warming during cardiopulmonary bypass with an LCT on their forehead, next to a thermocouple, the smallest correlation coefficient was 0.92. In 7.3% of observations in patients, the LCT scale was blurred, but readable. The graph relating LCT temperature and forehead thermocouple temperature showed hysteresis between the cooling and warming phases. An additional laboratory experiment suggested that LCT might be affected by draughts; they should therefore be protected from draught in use.

    The clinical evaluation, even today, remains a central point in the diagnosis, prognostic definition and treatment prescription regarding scoliosis. The clinical evaluation of a scoliotic patient has been established for a long time, but it has not been standardized. The aim of the present work is to report the most common clinical measures for the assessment of scoliosis, explain the usefulness of each clinical measurement, and report the repeatability and limits in order to help the physician in making appropriate clinical choices. The height of the hump, the angle of trunk rotation, the sagittal and frontal profiles, and the Trunk Aesthetic Clinical Evaluation (TRACE) have been fully described, and their reliability and repeatability have been assessed. The measures analyzed showed good reliability and repeatability on the intra-operator basis. The inter-operator repeatability is usually not that good. The main measures of the clinical assessment of scoliotic patients have been tested, and their reliability has been evaluated. The knowledge of measurement error, as well as intra- and inter-operator reliability, are essential for the clinical evaluation and treatment of scoliosis. This is an unavoidable basis for decision making in the assessment and the treatment of scoliosis.

    The most thorough and clinically relevant approach to hypnotic drug evaluation is one that balances the strengths and weaknesses of clinical trials and sleep laboratory evaluations. Advantages of clinical trials include the ability to evaluate large numbers of subjects and specific target groups and to thoroughly assess and quantify a drug's side effects, whereas sleep laboratory studies are very limited in all of these areas. Sleep laboratory studies however provide a rigorous, precise, and comprehensive profile of a drug's activity since there is more control over experimental variables and measurements are objective as well as continuous throughout the night. These benefits offset the shortcomings of clinical trials, which include a lack of objective measurements, less control over experimental variables, failure to evaluate a drug's effectiveness with continued use, and inattention to drug interaction and withdrawal effect. Several basic principles derived from sleep laboratory findings have been incorporated into both the clinical trials and sleep laboratory evaluations recommended in the new FDA Guidelines for the Clinical Evaluation of Hypnotic Drugs. These principles include provision for adequate baseline and withdrawal periods, use of multiple consecutive drug nights to assess a drug's effectiveness with continued use, and inclusion of an adequate washout period when a cross-over design is used. The guidelines do not emphasize either clinical trials or sleep laboratory studies at the expense of each other, but rather stress their complementary utilization.

    The aim of this investigation was to evaluate the efficacy and convenience of decayed dentine removal with N-monochloro-DL-2 aminobutyrate (CARIDEX) in all classes of cavities. Fifty-seven patients, each with two teeth having similarly sized carious cavities, participated in this study. One cavity in each patient was treated with the chemomechanical CARIDEX technique and the other cavity was treated with conventional mechanical drilling. The cavities were restored with either amalgam, composite or glass ionomer restorative materials. The time taken for access and caries removal was noted and the efficacy of caries removal with each technique was evaluated. The chemomechanical caries removal technique was effective in removing 90-100% of decayed dentine in 98% of the cavities treated. Multiple regression adjusted access and caries removal time to account for volume of caries removed. This adjusted time was operator dependent, and ranged from 4 to 10 minutes longer for CARIDEX than for the conventional technique. Ninety-three per cent of patients preferred the chemomechanical method of caries removal over the conventional technique (highly significant P less than 0.001). Even though the chemomechanical removal of caries is slower than the conventional technique, the efficacy of CARIDEX and its high patient acceptance provides a viable alternative method for dentinal caries removal in all classes of cavities.

    A 3-year-old male presented with progressive pruritic red-orange plaques across most of his body with erythema, desquamation, and fissuring of the hands and feet. He was diagnosed with classic juvenile (type III) pityriasis rubra pilaris (PRP) and treated with oral isotretinoin for 6 months. His skin findings resolved quickly during the treatment period, with residual postinflammatory hypopigmentation resolving within a year. PRP is rare in pediatric patients and standard recommended treatment algorithms for this population are not currently available. Diagnostic and treatment guidelines for PRP are based almost exclusively on case reports or case series, most of which focus on adult patients. The presentation, evaluation, and management of PRP are discussed. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

    Auditory neuropathy is a condition in which there is a change in the neuronal transmission of the auditory stimuli. Our objective was to describe the patients' series within the clinical spectrum of auditory neuropathy. We designed a transversal, retrospective study, with a description of a consecutive case series. Auditory neuropathy was defined by the presence of acoustic otoemissions plus absent/abnormal auditory brainstem responses with cochlear microphonism. 34 patients with bilateral hearing loss, 23 males and 11 females, were included in the study. Eighty percent of the cases had congenital onset of hearing loss. Acoustic otoemissions were absent in 67% of them. Cochlear microfonism was present in 79% of all cases. Prenatal, perinatal or ambiental factors were present in 35.2% of the cases. Medical literature shows great variability in findings related to auditory neuropathy, both in its etiology and epidemiological data. Auditory neuropathy presents a broad spectrum of changes that may result from mild to severe changes in the functioning of the auditory pathway, and in our sample we observed that 80% of Auditory neuropathy have congenital onset of hearing loss and/or with cochlear microphonism identified. 91% of patients experience significant hearing impairment and 53% suffer from severe or profound deafness.

    A report on a small clinical trial with a plastic intrauterine contraceptive device (Lippes loop) among South Indian women is presented. A total of 450 women were fitted with the IUDs and were observed from July 1966 to June 1967, with a total exposure of 1411 woman-months. Women aged 20-30 years comprised 73.3% of the cases. Two-thirds of the cases belonged to the 3-6 parity group. The complication rate was 21.1%. The commonest side effect was vaginal bleeding in 13.3% of the cases. The spontaneous expulsion rate was 5.5%, and the removal rate was 5.3%. The commonest reason for removal was vaginal bleeding. The pregnancy rate was 2.55 per 100 woman-years of exposure. A total of 52 women (11.5%) were found unsuitable for the device. Most of the insertions were performed within the first week of the menstrual period. It was concluded that the acceptance of the method was satisfactory.

    The clinical effectiveness of a new flossing device, the Floss Plus easy flosser, in reducing interproximal plaque and interproximal gingival inflammation was compared to the effectiveness of hand-held floss. The first phase studied 36 dental students, while the second studied 26 adult patients undergoing supportive periodontal treatment. In both phases, the subjects were divided into two groups. One group used the flossing device, while the second group used hand-held floss. The Gingival Index and Plaque Index were taken at baseline, 1 week, and 6 weeks. All groups experienced a significant decrease in the amount of interproximal inflammation and plaque, regardless of which flossing method was used. There was no statistically significant difference between the two flossing methods in the reduction of interproximal inflammation or plaque. These results indicated that the Floss Plus easy flosser is as effective as hand-held floss in reducing interproximal plaque and gingivitis. The use of this aid may benefit those patients who lack the dexterity for hand-held floss or who find flossing cumbersome.

    Vertigo is one of the usual menopausal symptoms. We have often examined some women under the complaint of vertigo related with the menopause. We diagnosed each disease based on neuro-otological examinations and investigated the characteristics of menopausal-associated vertigo. We studied 413 women aged 40-59 years old who complained of vertigo. There were 73 women with menopause symptoms (14 women introduced from the gynecologist in our medical center, 18 women had undergone treatment at another female clinic, and 41 women visited an otorhinolaryngologist first) compared with 340 women without menopause symptoms. In the menopause group, 41 (56.2%) cases were diagnosed as having benign paroxysmal positional vertigo (BPPV), 13 (17.8%) cases had Meniere's disease, sudden deafness with vertigo accounted 2 cases, one was an acoustic tumor, and so on. The percentage of patients with BPPV was almost same ratio between the menopause group (56.2%) and the non-menopause group (52.9%). The percentage of patients with Meniere's disease was higher markedly in the menopausal group (17.8%). than the non-menopause group (9.7%). Menopausal symptoms are caused not only by hot flashes related to a lack of estrogen but also by psychological factors. The onset of Meniere's disease can also be influenced by psychological factors. As for the diagnosis of Meniere's disease, we supposed the reason for the higher percentage in the menopausal group was its relationship with psychological factors. We could diagnose and treat some menopausal women with vertigo. We believe that joint consultation with a gynecologist and otorhinolaryngologist would be necessary to ensure an optimum quality of life for such patients.

    During the five years running from December 1993 to January 1998, 112 patients who had come to our University Clinic suffering from headache were examined. From this group 71 complaining of tinnitus during headache were recruited for the study: 19 patients suffered from migraine without aura, 8 migraine with aura, 15 tension headache, 21 mixed headache, 3 basic migraine and 5 cluster headache. The purpose of this work was to determine the incidence and to identify the frequency of the various types of tinnitus in the study sample. Once cardiovascular and metabolic pathologies, previous cranial or cervical traumas, barotrauma, chronic on-the-job noise exposure, cervical arthritis, ATM malocclusion, use of drugs that damage the hearing apparatus, morbose processes of the external and middle ear, otosclerosis, jugular tympanum paraganglioma, Meniere's disease, acoustic neurinoma were all ruled out, the patients underwent the following battery of instrumental tests: tonal audiometry, impedance measurement, vestibular examination, electronystagmography, ABR, simplified tinnitometry. Only those patients with normal hearing underwent the tinnitometry and, therefore, the type of tinnitus was established only for this group of 53 patients. Tinnitometry showed that 37% of these subjects had tinnitus at the higher frequency tones, 11% at the middle frequencies, 29% complained of tinnitus at the lower frequencies while 23% complained that the bothersome buzzing was a compound noise. In addition, the subjective intensity of the tinnitus was analyzed. The authors devised a tinnitus irritation scale covering a range from 0 (not irritating) to 10 (intolerable). The tinnitus was bilateral in 66% of the cases while it was limited to only one ear in the remaining 34%. In 15% of the cases tinnitus was present even when there was no headache. In the literature, the etiopathogenesis of tinnitus associated with migraine headache has been attributed to vascular and neuropeptide mechanisms

    Sparse data are available concerning the survival rate of porcelain inlays or onlays to inform the dentist and address the expectations of patients. A total of 25 posterior porcelain inlays were inserted by two dentists at a private Danish clinic; the time elapsed since cementation was 20 to 57 months (average 40.4 months). Tooth preparations for MOD porcelain inlays were completed for 13 premolars and 12 molars but most did not include cuspal coverage. All inlays were constructed at the same commercial dental laboratory and according to the manufacturer's recommendations; they were etched and treated with silane before they were cemented. The cementation included etching of cavosurface enamel and treatment of the dentin with a dentinal bonding system. A thin layer of composite resin luting agent was applied to the tooth preparation before the porcelain inlays were cemented. The first 10 porcelain inlays were cemented with a light-curing composite resin cement and the remaining 11 with a dual-curing composite resin cement. Twelve of the 25 porcelain inlays failed and were replaced during the observation period. Ten failures were due to a fracture of the inlay, one was caused by secondary caries, and the final failure was attributed to a marginal gap between the inlay and proximal tooth surface. Porcelain inlays cemented with light-curing composite resin exhibited more failures (p = 0.05) than those cemented with dual-curing composite resin. In addition, more failures (p = 0.07) were recorded among inlays inserted in molars than among those in premolars.

    Introduction The child who chronically breathes through the mouth may develop a weakness of the respiratory muscles. Researchers and clinical are seeking for methods of instrumental evaluation to gather complementary data to clinical evaluations. With this in mind, it is important to evaluate breathing muscles in the child with Mouth Breathing. Objective To develop a review to investigate studies that used evaluation methods of respiratory muscle strength in mouth breathers. Data Synthesis  The authors were unanimous in relation to manovacuometry method as a way to evaluate respiratory pressures in Mouth Breathing children. Two of them performed with an analog manovacuometer and the other one, digital. The studies were not evaluated with regard to the method efficacy neither the used instruments. Conclusion There are few studies evaluating respiratory muscle strength in Mouth Breathing people through manovacuometry and the low methodological rigor of the analyzed studies hindered a reliable result to support or refuse the use of this technique.

    Encouraged by the increased purchasing power of general practitioners (GPs), specialist-run clinics in general practice and community health care settings (known as specialist outreach clinics) have increased rapidly across England. The activities of local commissioning schemes within primary care groups are likely to accelerate this trend. To evaluate the costs, processes, and benefits of specialists' outreach clinics held in GPs' surgeries, compared with hospital outpatient clinics. A case-referent (comparative) study comparing the characteristics of outreach clinics (cases) with matched outpatient control clinics. Thirty-eight outreach clinics, compared with 38 matched outpatient clinics as controls, covering 14 hospital trust areas across England. Self-administered questionnaires were given to patients in both clinic settings. These covered processes, satisfaction, personal costs, and health status, with postal follow-up at six months to assess health outcomes. Self-administered questionnaires were also given to the specialists and GPs whose clinics were included in the study (individual patient clinical sheet and an attitude questionnaire), practice managers, and trust accountants (process and costs questionnaire). Evaluation of the costs, processes, and benefits of specialist outreach clinics versus hospital outpatient clinics was carried out by comparing questionnaire responses. In comparison with outpatients, outreach clinic patients spent less time on the waiting lists for appointments to see the specialist, they had shorter waiting times in clinics, fewer follow-up appointments, and were more likely to be completely discharged after the sampled attendance. Outreach patients were more satisfied than outpatients with the range of clinic process items asked about. Most doctors felt that the outreach clinic was 'worthwhile'. While patients' personal costs were lower in outreach than in outpatients clinics, NHS costs were more expensive per patient in outreach

    2011-01-01

    Objective To implement and assess the effectiveness of an activity to teach pharmacy students to critically evaluate clinical literature using instructional scaffolding and a Clinical Trial Evaluation Rubric. Design The literature evaluation activity centered on a single clinical research article and involved individual, small group, and large group instruction, with carefully structured, evidence-based scaffolds and support materials centered around 3 educational themes: (1) the reader's awareness of text organization, (2) contextual/background information and vocabulary, and (3) questioning, prompting, and self-monitoring (metacognition). Assessment Students initially read the article, scored it using the rubric, and wrote an evaluation. Students then worked individually using a worksheet to identify and define 4 to 5 vocabulary/concept knowledge gaps. They then worked in small groups and as a class to further improve their skills. Finally, they assessed the same article using the rubric and writing a second evaluation. Students’ rubric scores for the article decreased significantly from a mean pre-activity score of 76.7% to a post-activity score of 61.7%, indicating that their skills in identifying weaknesses in the article's study design had improved. Conclusion Use of instructional scaffolding in the form of vocabulary supports and the Clinical Trial Evaluation Rubric improved students’ ability to critically evaluate a clinical study compared to lecture-based coursework alone.

  18. Clinical evaluation of the overweight patient.

    PubMed

    Bray, G A; Ryan, D H

    Evaluation of an overweight patient is the first step in any therapeutic program. The syndromes of obesity can be classified in several ways. The first is an anatomic classification based on the size, number, and distribution of fat cells and fat tissue. The second is an etiologic classification based on identification of specific diseases and settings that produce obesity. Hypothalamic injury and endocrine disease such as Cushing's disease and the polycystic ovary syndrome are three identifiable causes of obesity. In this medicated society drugs are always candidates to produce weight gain. The most common causes, however, are stopping smoking, overconsumption of high-fat foods, a decrease in the level of activity, and aging. The natural history of obesity provides a useful framework in which to view both preventive and therapeutic strategies. Some individuals will never become overweight, but of those who do, about one-third will do so during the first two decades, and the remaining two-thirds will become overweight after age 20. A number of epidemiological and metabolic factors can serve as a guide to those individuals who are at high risk. Having overweight parents tops the list, but multiple births, cessation of smoking, and a sedentary lifestyle are additional factors. Therapeutic decisions should be based on risk-benefit decisions. The risk can be assessed from the body mass index, the distribution of fat in upper or lower body obesity, the rate of weight gain, and the degree of physical inactivity. After assessing risk, the therapeutic choices can be selected from the age category of the patient. With any therapeutic activity, involvement of the patient in a realistic approach to the treatment process is essential.

    The present work aims to evaluate the mobility of the polyethylene bearing in 25 patients implanted with a mobile-bearing PCL-retaining TKR (Interax ISA, Striker Howmedica) under in vivo, weight-bearing conditions over 3 years' follow-up. We compared the bearing motion in response to specific tests in two consecutive follow-ups with Roentgen Stereophotogrammetric Analysis (RSA). Results showed that polyethylene continued to displace on the tibial baseplate over time: longitudinal rotations and medio-lateral translations tended to increase at the second follow-up (mean increases 0.7+/-2.5 degrees and 0.34+/-1.08 mm, respectively), while sagittal translations did not show any relevant change. Longitudinal rotations and AP translations were preserved when present at both follow-ups. Nevertheless, no statistical evidence of repeatable pattern of motion was found, since bearings frequently reversed their pattern of motion between the two follow-ups. The unconstrained polyethylene mobility resulted in an unrepeatable, erratic pattern of bearing motion intra-patient and over time. The changes in knee motion were found not to affect the clinical results over the first 3 years of follow-up. As in a fixed-bearing design, mobile-bearing design was not able to reproduce normal knee kinematics.

    The idea of the preoperative anesthesia clinic as a means of examining and treating the patient so that he will arrive in the operating theater as strong and healthy as possible is well established in practice and literature.However, problems in clinic design and execution often result in high patient waiting times, decreased patient and staff satisfaction, decreased patient capacity, and high clinic costs. Although the details of clinic design, outcomes, and satisfaction have been extensively evaluated at civilian hospitals, we have not found corresponding literature addressing these issues specifically within military preoperative evaluation clinics. We find that changing to an appointment-based (versus walk-in) system and eliminating data collection step redundancies will likely result in lower wait times, higher satisfaction, lower per patient costs, and a more streamlined and resource-efficient structure.

    One hundred twenty-five lower limbs with varicose veins were studied clinically, essentially by palpation. Two specialists in venous pathology scored the severity of the varicose veins from 0 to 20. Comparison between the different clinical parameters and the scores of the specialists showed that two systems of clinical quantification gave good results and were easy to use. One system is the maximum diameter of the largest varicose vein; the other system is the sum of maximum diameters over 7 sections (3 for thigh, 3 for leg, 1 for foot). This latter system gives a more precise evaluation of the clinical severity of the varicose veins.

    Clinical librarian services have been in existence for over 40 years. Although three systematic reviews have examined clinical librarian roles they continue to pose a challenge to rigorous evaluation. Difficulties can be articulated around their Population, Intervention, Comparator and Outcome (PICO) characteristics as well as within a wider evaluation framework. This feature suggests that developments within health research aimed at evaluating complex interventions may hold the key to assessing the contribution of such a variety of service models. © 2010 The authors.

    Our purpose was to implement and evaluate an orientation program for residents, focusing on outpatient clinical skills. Eleven of 12 residents participated in a clinical skills orientation program immediately preceding the academic year. The skill stations included evaluation of abnormal uterine bleeding, intrauterine device insertion, basic infertility evaluation, endometrial and vulvar biopsies, pelvic organ prolapse quantification examination, hysterosalpingography and office hysteroscopy, ultrasound scanning, labor and delivery triage, and clinic administrative responsibilities. Before test, after test, and anonymous resident evaluations were used to evaluate the program. First-year residents demonstrated a statistically significant increase in posttest scores compared to pretest scores (42.5% vs 71.3%, P=.003). Only first-year resident posttest scores for the labor and delivery triage and basic infertility evaluation stations demonstrated statistically significant increases over pretest scores (14.3% vs 46.4%, P=.009; and 41.7% vs 83.3%, P=.049, respectively). Sixty-four percent of the residents rated the program as "very helpful." Most residents felt that the program was well organized and that the facilities were conducive to learning; all of the participants recommended an annual clinical orientation program. A clinical skills orientation program was well received and strongly desired by residents. First-year residents appeared to benefit the most from this orientation.

    The aim of this study was to investigate the 3-year morbidity of coronectomy of the lower third molar and to monitor the behaviour and migration pattern of the retained roots postoperatively. A total of 92 patients (111 teeth) who had undergone a coronectomy between October 2005 and July 2009 were investigated. Patients were followed up at 3 months and 1, 2, and 3 years for clinical evaluation and dental computed tomography imaging of the coronectomy sites. In total, 10 cases (9%) required tooth root extraction within the 3 years after coronectomy. In seven of them, the distal pocket of the lower second molars remained connected to the roots within the first year. Of the cases in whom a pocket did not remain at an early stage, none showed peri-apical lesions on transmission images of the retained roots in the apical area, which usually result from necrosis of the pulp. Root migration increased in the first 2 years after coronectomy but stabilized between the second and third years. In addition, a significant difference was noted in root migration between patients of different ages and sex. Retained roots after coronectomy in the lower third molars led to no complications in terms of infection or the development of pathologies within the first 3 years postoperatively.

    Introduction Vital pulp therapy is a major contributor in the preservation of primary dentition after caries affliction. Introduction of mineral trioxide aggregate (MTA) has revolutionized such treatment. Aim The aim of our study was to evaluate and correlate the effects of MTA clinically and radiographically on pulpotomized primary molars till their exfoliation or extraction followed by histological evaluation. Study design This is an observational study. Materials and methods A total of 25 teeth were selected from 5- to 8-year-old children requiring pulp therapy on the basis of inclusion and exclusion criterion. The teeth were treated by conventional pulpotomy technique under aseptic conditions using MTA and were immediately restored with stainless steel crown. The teeth were assessed postoperatively till 36 months. The exfoliated or extracted teeth were examined histologically. Results The pulpotomized teeth were vital with no adverse clinical findings during the observation period. After 3 months, one tooth showed internal resorption, but the same was not observed after 12 months. Pulp canal obliteration was seen in three cases. At the end of the study, five teeth were exfoliated and one tooth was extracted for maintaining arch symmetry. The histological examination of extracted tooth revealed the presence of healthy pulp and the area of true calcification. Remaining exfoliated teeth presented dentin bridge formation. Statistics Frequencies and percentages were used for descriptive statistics. Fisher’s exact tests were used to see the difference between clinical and radiological findings. The probability value was fixed at 5% level of significance. Conclusion The response of pulp in primary teeth to MTA was favorable in all cases from clinical and radiographic perspective, and histological evaluation confirmed the observation.

    Patients scheduled for surgery at the Omaha VA Medical Center were evaluated preoperatively via telemedicine. Following the examination, patients filled out a 15 item, 5 point Likert scale questionnaire regarding their opinion of preoperative evaluation in a VTC format. Evaluations were performed under the direction of nationally recognized guidelines and recommendations of experts in the field of perioperative medicine and were overseen by a staff anesthesiologist from the Omaha VA Medical Center. No significant difficulties were encountered by the patient or the evaluator regarding the quality of the audio/visual capabilities of the VTC link and its ability to facilitate preoperative evaluation. 87.5% of patients felt that virtual evaluation would save them travel time; 87.5% felt virtual evaluation could save them money; 7.3% felt uncomfortable using the VTC link; 12.2% felt the virtual evaluation took longer than expected; 70.7% preferred to be evaluated via VTC link; 21.9% were undecided; 9.7% felt they would rather be evaluated face-to-face with 26.8% undecided; 85.0% felt that teleconsultation was as good as being seen at the Omaha surgical evaluation unit; 7.5% were undecided. Our study has shown that effective preoperative evaluation can be performed using a virtual preoperative evaluation clinic; patients are receptive to the VTC format and, in the majority of cases, prefer it to face-to-face evaluation.

    Necessity of imaging for symptom-free conscious patients presented to emergency department (ED) following traumatic thoracolumbar spine injuries has been a matter of debate. The present study was aimed to evaluate the diagnostic value of clinical findings in prediction of traumatic thoracolumbar injuries compared tocomputed tomography (CT) scan. The present diagnostic value study was carried out using non-random convenience sampling during the time between October 2013 and March 2014. All trauma patients > 15 years old underwent thoracolumbar CT scan were included. Correlation between clinical and CT findings was measured using SPSS 21.0 and screening performance characteristics of clinical findings in prediction of thoracolumbar fracture were calculated. 169 patients with mean age of 37.8 ± 17.3 years (rage: 15-86) were evaluated (69.8% male). All fracture patients had at least 1 positive finding in history and physical examination. The fracture was confirmed in only 24.6% of the patients with positive findings in history or physical examination. In 37.5% of patients the location of fracture, matched the area of positive physical examinations. Sensitivity, specificity, PPV, NPV, PLR, and NLR of clinical findings in comparison to thoracolumbar CT scan were 100 (95% CI: 89 - 100), 1.5 (95% CI: 0.2-6), 24.5 (95% CI: 18.3-31.9), 100 (95% CI: 19.7-100), 32.5 (95% CI: 24.6-43.03), and infinite, respectively. The results of the present study, show the excellent screening performance characteristics of clinical findings in prediction of traumatic thoracolumbar fracture (100% sensitivity). It could be concluded that in conscious patients with stable hemodynamic, who have no distracting pain and are not intoxicated, probability of thoracolumbar fracture is very low and near to zero in case of no positive clinical finding.

    In the present report, the 3-year outcomes of 23 consecutive patients treated with a modular stem fixed-bearing total ankle replacement are described. Pain, functional impairment, and disability were assessed annually using a visual analog scale. Complications and additional procedures also were recorded. Compared with preoperative pain (8.4 ± 1.4), functional impairment (8.7 ± 2.3), and disability (3.0 ± 2.5), there were statistically significant postoperative improvements at 1 year (pain, 2.6 ± 1.6; functional impairment, 3.1 ± 2.1; disability, 0.9 ± 1.2), 2 years (pain, 1.5 ± 1.3; functional impairment, 1.9 ± 1.4; disability, 0.6 ± 1.4), and 3 years (pain, 1.3 ± 1.3; functional impairment, 1.9 ± 1.9; disability, 0.4 ± 0.9; p ≤ .001). Pain, function, and disability significantly improved postoperatively from 1 to 2 years (p ≤ .008) and from 1 to 3 years (p ≤ .008). The reductions in pain, functional impairment, and disability were maintained from 2 to 3 years (p ≥ .08). Nine complications (39.1%) were encountered: 1 deep infection, 2 pulmonary embolisms, 3 wounds, 1 ectopic bone formation, 1 stiff joint, and 1 talar subsidence. In the 3-year follow-up period, 3 patients (13.0%) required additional procedures after the immediate postoperative phase. Our results have demonstrated that modular stem fixed-bearing prostheses can be implanted in a predictable and consistent fashion with resultant improvements in pain, function, and disability. Future studies evaluating the clinical outcomes after modular stem fixed-bearing total ankle replacement are warranted.

  12. [Clinical evaluation of thrombo-embolic venous disease].

    PubMed

    Chagnon, Isabelle

    2003-01-01

    Clinical manifestations of venous thromboembolism are often subtle or misleading. Yet it is a potentially fatal condition. Although the symptoms and signs at presentation have a poor sensitivity and specificity when considered singly, the physician can accurately assess a clinical probability based on the history, the risk factors, the physical examination and some simple laboratory exams. This essential step allows us to identify a low risk group of patients which will benefit of a non invasive diagnostic strategy. More recently explicit prediction rules were proposed to offset the lack of standardization of this clinical assessment. These new didactic tools can simplify clinical evaluation. Nevertheless, their comparison to implicit evaluation reveals that they should be complemented by the physician's judgement.

    Clinical pathways are comprehensive systematized patient care plans for specific procedures. The clinical pathway for laparoscopic cholecystectomy was implemented in our department in March 2002. The aim of this study is to evaluate the clinical pathway for this procedure 1 year after implementation. A study was conducted on all the patients included in the clinical pathway since its implementation. The assessment criteria include degree of compliance, indicators of clinical care effectiveness, financial impact, and survey-based indicators of satisfaction. The results are compared to a series of patients undergoing surgery the year prior to implementation of the clinical pathway. As our hospital has a system of cost management, we analyzed the mean cost per procedure before and after clinical pathway implementation. Evaluation was made of a series of 160 consecutive patients who underwent surgery during the period 1 year prior to development of the clinical pathway and met the accepted inclusion criteria. The mean length of hospital stay was 3.27 days, and the mean cost per procedure before pathway implementation was 2149 (+/-768) euros. One year after implementation of the pathway, 140 patients were included (i.e., an inclusion rate of 100%). The mean length of hospital stay of the patients included in the clinical pathway was 2.2 days. The degree of compliance with stays was 66.7 per cent. The most frequent reasons for noncompliance were staff-dependent, followed by patient-dependent causes (oral intolerance, pain, etc.). The mean cost in the series of patients included in the clinical pathway was 1845 (+/-618) euros. Laparoscopic cholecystectomy is an ideal procedure for commencing the systemization of clinical pathways. Results show that it has significantly reduced the length of hospital stay and mean cost per procedure with no increased morbidity and with a high degree of patient satisfaction.

    A previous study provided information regarding the quality of in-clinic veterinary biochemistry testing. However, no similar studies for in-clinic veterinary hematology testing have been conducted. The objective of this study was to assess the quality of hematology testing in veterinary in-clinic laboratories using results obtained from testing 3 levels of canine EDTA blood samples. Clinicians prepared blood samples to achieve measurand concentrations within, below, and above their RIs and evaluated the samples in triplicate using their in-clinic analyzers. Quality was assessed by comparison of calculated total error with quality requirements, determination of sigma metrics, use of a quality goal index, and agreement between in-clinic and reference laboratory instruments. Suitability for statistical quality control was determined using adaptations from the computerized program, EZRules3. Evaluation of 10 veterinary in-clinic hematology analyzers showed that these instruments often fail to meet quality requirements. At least 60% of analyzers reasonably determined RBC, WBC, HCT, and HGB, when assessed by most quality goal criteria; platelets were less reliably measured, with 80% deemed suitable for low platelet counts, but only 30% for high platelet counts, and automated differential leukocyte counts were generally considered unsuitable for clinical use with fewer than 40% of analyzers meeting the least stringent quality goal requirements. Fewer than 50% of analyzers were able to meet requirements for statistical quality control for any measurand. These findings reflect the current status of in-clinic hematology analyzer performance and provide a basis for future evaluations of the quality of veterinary laboratory testing. © 2016 American Society for Veterinary Clinical Pathology.

    The Clinical Immersion Model is an innovative baccalaureate nursing curriculum that has demonstrated successful outcomes over the past 10 years. For those intending to adopt the model, individual components in isolation may prove ineffective. This article describes three core components of the curriculum that form the foundation of preparation for the senior-year clinical immersion. Detailed student-centered outcomes evaluation of these critical components is shared. Results of a mixed-methods evaluation, including surveys and focus groups, are presented. Implications of this curricular evaluation and future directions are explored.

    2013-01-01

    The mini-clinical evaluation exercise (mini-CEX) is a sort of test in which the assessor's evaluation is based on a short observation of the resident in a clinical situation. A mini-CEX is not an examination but a useful educational instrument to monitor and to foster the resident's development. The central concepts of a good mini-CEX are 'short' (limited both in content and duration) and 'often' (the more frequent the better). It is important the assessor should provide feedback as soon as possible after the evaluation; this feedback should be constructive and task-oriented and be presented to the resident in a credible manner. Multiple observations by different assessors will ensure that the overall picture of the resident's progress is more reliable. Because the particular value of the mini-CEX lies mainly in the repetition involved, we would like to replace the 'E' for 'evaluation' with the 'G' for 'guidance'.

    OBJECT Acute cervical spine injuries have been extensively studied in high-level contact sports. However, the relation between the appearance of degenerative cervical spine disease and the exposure to repeated trauma in such sports as rugby is still unclear. Using clinical and MRI evaluation, we aimed to determine if former professional rugby players had more serious degenerative cervical spine symptoms than the general population. METHODS Two groups, one composed of 101 former rugby players (all men, mean age 40.3 years, range 35-47 years, SD 2.3 years) and the other of 85 male volunteers serving as a control group (mean age 41.6 years, range 35-49 years, SD 4.5 years) were studied. The former rugby players were evaluated on average 5.8 years after retirement (range 1-16 years, SD 3.5 years). The groups were matched in terms of sex, age, job, current sports training, and smoking habits. Each participant received a complete neurological evaluation. Clinical symptoms were evaluated using the Japanese Orthopaedic Association (JOA) questionnaire, and chronic neck pain was specifically evaluated using a visual analog scale (VAS) and the Neck Disability Index (NDI). Overall, 25 MRI studies were performed in each group. MRI studies, including dynamic sequences, focused on degenerative lesions (Matsumoto score and canal diameter) and on muscular and medullary morphological analysis. RESULTS Significantly more former rugby players than controls complained of chronic neck pain (51 [50.50%] of 101 vs 27 [31.76%] of 85, p = 0.01). Rugby players also had significant reductions of neck mobility. Nevertheless, in those complaining of pain, there was no statistically significant difference between groups with respect to VAS and NDI scores (p = 0.57). On MRI, former rugby players had a narrower vertebral canal (on average 0.88 ± 0.167 cm vs 0.99 ± 0.130 cm, p = 0.007) and more foraminal stenosis (p = 0.01). No significant difference in the Matsumoto score was found between the 2

    To evaluate yearly cost of glaucoma medications at a university-affiliated teaching hospital with its own health maintenance organization from 1998 through 2000. We retrieved data from the Scott and White prescription claims file for 1,484 patients concerning Health Plan glaucoma-medication prescriptions for the years 1998 through 2000. Patient inclusion criteria were as follows: 1) use of a single or fixed-combination topical glaucoma medication during all four quarters of at least one full-year, 2) treatment of both eyes, 3) participation in the Health Plan prescription program, and 4) prescriptions filled at pharmacies participating in the Health Plan prescription program. Over this 3-year period, the most costly medication per patient per year was dorzolamide hydrochloride-timolol maleate (Cosopt; Merck, West Point, PA [$470]), followed by betaxolol hydrochloride (Betoptic-S; Alcon, Fort Worth, TX [$370]), latanoprost (Xalatan; Pharmacia and Upjohn, Kalamazoo, MI [$352]), dorzolamide hydrochloride (Trusopt; Merck, West Point, PA [$288]), brimonidine tartrate (Alphagan; Allergan Pharmaceuticals, Irvine, CA [$273]), brinzolamide (Azopt; Alcon, Fort Worth, TX [$243]), timolol maleate 0.5% in a gel-forming solution (Timoptic-XE 0.5%; Merck, West Point, PA [$190]), carteolol hydrochloride (Ocupress; Otsuka Pharmaceutical, Rockville, MD [$183]), generic levobunolol hydrochloride 0.5% ($138), metipranolol (Optipranolol; Bausch and Lomb Pharmaceuticals, Tampa, FL [$135]), and generic timolol maleate 0.5% ($133). Differences in yearly cost exist among topical glaucoma medications.

    Clinical performance evaluations are major components of medical school clerkship grades. But are they sufficiently objective? This study aimed to determine whether student and evaluator gender is associated with assessment of overall clinical performance. This was a retrospective analysis of 4,272 core clerkship clinical performance evaluations by 829 evaluators of 155 third-year students, within the Alpert Medical School grading database for the 2013-2014 academic year. Overall clinical performance, assessed on a three-point scale (meets expectations, above expectations, exceptional), was extracted from each evaluation, as well as evaluator gender, age, training level, department, student gender and age, and length of observation time. Hierarchical ordinal regression modeling was conducted to account for clustering of evaluations. Female students were more likely to receive a better grade than males (adjusted odds ratio [AOR] 1.30, 95% confidence interval [CI] 1.13-1.50), and female evaluators awarded lower grades than males (AOR 0.72, 95% CI 0.55-0.93), adjusting for department, observation time, and student and evaluator age. The interaction between student and evaluator gender was significant (P = .03), with female evaluators assigning higher grades to female students, while male evaluators' grading did not differ by student gender. Students who spent a short time with evaluators were also more likely to get a lower grade. A one-year examination of all third-year clerkship clinical performance evaluations at a single institution revealed that male and female evaluators rated male and female students differently, even when accounting for other measured variables.

    To describe the clinical and radiological features of children with inverted supernumerary teeth. Thirty eight patients with inverted supernumerary teeth (ST) were enrolled in this descriptive and restrospective study. Data from patient records including age, gender, status of dentition, number of ST, number of ST in inverted position, coexistence of ST in inverted and normal direction of eruption, location, orientation, morphology, clinical complications, management and radiography were assessed during 3-years period. Thirty eight patients with a mean age of 9.10 ± 1.97 years (range:6-13) and a strong male preponderance of 3.7:1 (male:30, female:8) had a total of 69 ST, of which 41 were in inverted position. Thirty five patients had one (92.1%) inverted tooth, whereas 3 patients had two inverted teeth per case (7.9%). All cases were located in the maxilla. Midline was the most frequent site for the single inverted supernumerary tooth in 18 (47.4%) patients, followed equally by the right and left premaxillary region in 10 patients each (26.3%). Regarding morphology, 30 patients had conical (78.9%) and 8 (21.1%) had incisiform ST. No tuberculate shaped ST was detected. There was no statistically significant difference between number of inverted teeth and delayed tooth eruption, diastema, local malocclusion, palatinal swelling (p>0.05). There was no statistically significant difference between complications and age (p>0.05). Surgical removal at the time of diagnosis with subsequent follow-up during completion of permanent dentition was the treatment approach in all cases. Thorough clinical examination followed by a comprehensive radiographic screening is the crucial determinant of an accurate diagnosis of an impacted ST. Early diagnosis and timely management are key factors to prevent or minimize the complications, which may influence function and esthetics of the teeth and even psychological condition of the growing child.

    Evaluation of clinical ethics support services (CESS) has attracted considerable interest in recent decades. However, few evaluation studies are explicit about normative presuppositions which underlie the goals and the research design of CESS evaluation. In this paper, we provide an account of normative premises of different approaches to CESS evaluation and argue that normativity should be a focus of considerations when designing and conducting evaluation research of CESS. In a first step, we present three different approaches to CESS evaluation from published literature. Next to a brief sketch of the well-established approaches of 'descriptive evaluation' and 'evaluation of outcomes', we will give a more detailed description of a third approach to evaluation-'reconstructing quality norms of CESS'-which is explicit about the normative presuppositions of its research (design). In the subsequent section, we will analyse the normative premises of each of the three approaches to CESS evaluation. We will conclude with a brief argument for more sensitivity towards the normativity of CESS and its evaluation research.

    In Machado-Joseph disease, poor posture, dystonia and peripheral neuropathy are extremely predisposing to oropharyngeal dysphagia, which is more commonly associated with muscular dystrophy. To evaluate the clinical characteristics of oropharyngeal dysphagia in Machado-Joseph disease patients. Forty individuals participated in this study, including 20 with no clinical complaints and 20 dysphagic patients with Machado-Joseph disease of clinical type 1, who were all similar in terms of gender distribution, average age, and cognitive function. The medical history of each patient was reviewed and each subject underwent a clinical evaluation of deglutition. At the end, the profile of dysphagia in patients with Machado-Joseph disease was classified according to the Severity Scale of Dysphagia, as described by O'Neil and collaborators. Comparison between dysphagic patients and controls did not reveal many significant differences with respect to the clinical evaluation of the oral phase of deglutition, since afflicted patients only demonstrated deficits related to the protrusion, retraction and tonus of the tongue. However, several significant differences were observed with respect to the pharyngeal phase. Dysphagic patients presented pharyngeal stasis during deglutition of liquids and solids, accompanied by coughing and/or choking as well as penetration and/or aspiration; these signs were absent in the controls. Oropharyngeal dysphagia is part of the Machado-Joseph disease since the first neurological manifestations. There is greater involvement of the pharyngeal phase, in relation to oral phase of the deglutition. The dysphagia of these patients is classified between mild and moderate.

    The purpose of this study was to examine the accuracy and reliability of a wide range of clinical thermometry instruments and technologies. In a historical sense, the purpose of this study was to determine if the improvements in speed, ease of use, and safety realized in the last 100 years have been offset by a loss of accuracy and/or reliability. In view of current events, the purpose was to determine if the new generation of electronic, digital clinical thermometers could be used to replace the traditional glass/mercury thermometers. Nine clinical thermometers representing electronic, digital oral, and predictive oral; electronic, digital infrared tympanic; and liquid crystal urinary technologies were evaluated. Accuracy was determined by comparing the temperatures obtained from these test instruments with those of the reference, glass/mercury oral thermometer. Reliability was determined by test-retest evaluation. All of the thermometers evaluated were significantly less accurate when compared with the reference thermometer in this study. All of the test instruments significantly underestimated higher temperatures and overestimated lower temperatures. This study indicated that the improvements in safety, speed, and ease of use of the newer clinical thermometers have been offset by a loss in accuracy and reliability. It also indicated that the current generation of electronic, digital clinical thermometers, in general, may not be sufficiently accurate or reliable to replace the traditional glass/mercury thermometers.

    2016-12-01

    We propose a methodological framework for evaluating clinical cognitive activities in complex real-world environments that provides a guiding framework for characterizing the patterns of activities. This approach, which we refer to as a process-based approach, is particularly relevant to cognitive informatics (CI) research-an interdisciplinary domain utilizing cognitive approaches in the study of computing systems and applications-as it provides new ways for understanding human information processing, interactions, and behaviors. Using this approach involves the identification of a process of interest (e.g., a clinical workflow), and the contributing sequences of activities in that process (e.g., medication ordering). A variety of analytical approaches can then be used to characterize the inherent dependencies and relations within the contributing activities within the considered process. Using examples drawn from our own research and the extant research literature, we describe the theoretical foundations of the process-based approach, relevant practical and pragmatic considerations for using such an approach, and a generic framework for applying this approach for evaluation studies in clinical settings. We also discuss the potential for this approach in future evaluations of interactive clinical systems, given the need for new approaches for evaluation, and significant opportunities for automated, unobtrusive data collection.

  9. A General Framework for the Evaluation of Clinical Trial Quality

    PubMed Central

    Berger, Vance W.; Alperson, Sunny Y.

    2009-01-01

    Flawed evaluation of clinical trial quality allows flawed trials to thrive (get funded, obtain IRB approval, get published, serve as the basis of regulatory approval, and set policy). A reasonable evaluation of clinical trial quality must recognize that any one of a large number of potential biases could by itself completely invalidate the trial results. In addition, clever new ways to distort trial results toward a favored outcome may be devised at any time. Finally, the vested financial and other interests of those conducting the experiments and publishing the reports must cast suspicion on any inadequately reported aspect of clinical trial quality. Putting these ideas together, we see that an adequate evaluation of clinical quality would need to enumerate all known biases, update this list periodically, score the trial with regard to each potential bias on a scale of 0% to 100%, offer partial credit for only that which can be substantiated, and then multiply (not add) the component scores to obtain an overall score between 0% and 100%. We will demonstrate that current evaluations fall well short of these ideals. PMID:19463104

    The objectives of this review were to summarize and evaluate studies that measured the economic impact of clinical pharmacy services published between 2001 and 2005 (inclusive) and to provide guidance on methodologic considerations to individuals performing such research in the future. A systematic literature search using the MEDLINE and International Pharmaceutical Abstracts databases was conducted to identify published economic evaluations of clinical pharmacy services. Studies were screened and then randomly assigned to reviewers, who reassessed inclusion and exclusion criteria and abstracted prespecified data from each study. Among the many characteristics examined in each study were study design and type of economic evaluation, setting and type of clinical pharmacy service, study quality, and results. Ninety-three articles were included in the final analysis. These studies were published in 43 different journals, most of which (68 [73.1%]) were pharmacy-based. Most studies were performed in hospitals (40 [43.0%]), ambulatory care clinics or physician's offices (20 [21.5%]), or community pharmacies (16 [17.2%]). The most common types of clinical pharmacy services evaluated were general pharmacotherapeutic monitoring services (32 [34.4%]), target drug programs (27 [29%]), and disease state-management services (21 [22.6%]). Full economic evaluations were performed in just less than half (45 [48.4%]) of the studies, and a positive economic benefit associated with clinical pharmacy services was noted in 31 (69%) of the 45 studies. Among 15 studies reporting data necessary to determine a benefit:cost ratio, the pooled median value was 4.81:1-meaning that for every $1 invested in clinical pharmacy services, $4.81 was achieved in reduced costs or other economic benefits. The quality of studies varied widely, with less than one half considered to be good to fair (40 [43.0%]); however, the proportion of studies using appropriate study designs increased compared with

    Neurogastroenterology and motility disorders of the gastrointestinal (GI) tract encompass a broad spectrum of diseases involving the GI tract and central nervous system. They have varied pathophysiology, clinical presentation and management, and make up a substantial proportion of outpatient clinic visits. Typically, patients experience persistent symptoms referable to the GI tract despite normal endoscopic and radiologic findings. An appropriate evaluation is thus important in the patient’s care. Advances in technology and understanding of the disease pathophysiology have provided better insight into the physiological basis of disease and a more rational approach to patient management. While technological advances serve to explain patients’ persistent symptoms, they should be balanced against the costs of diagnostic tests. This review highlights the GI investigative modalities employed to evaluate patients with persistent GI symptoms in the absence of a structural lesion, with particular emphasis on investigative modalities available locally and the clinical impact of such tools.

    2004-11-01

    To supplement the American Board of Orthodontics (ABO) objective grading system (OGS) for posttreatment dental casts and panoramic radiographs, a comprehensive clinical assessment (CCA) method was developed to assess facial form, dental esthetics, vertical dimension, arch form, periodontium preservation, root resorption, and treatment efficiency. The sum of the CCA and the ABO OGS scores was defined as the clinical outcome. To determine a 3-year baseline for treatment outcomes in a graduate orthodontic program, the posttreatment records of 521 consecutive patients were evaluated. The mean ABO OGS score for the entire sample was 34.4 points: 32.4, 33.1, and 37.8 points for 1998, 1999, and 2000, respectively. The mean CCA score for the entire sample was 4.67 points: 2.96, 5.13, and 6.15 points for 1998, 1999, and 2000, respectively. Corresponding ABO OGS and CCA scores showed a progressive decrease in the quality of finished cases that was associated with a treatment time increase from 28.9 to 39.3 months. Overall, longer active treatment times resulted in a diminished clinical outcome, primarily due to "patient burn-out." Scoring of all finished cases is an effective means for determining clinical outcomes. However, the data suggest that, in initiating a clinical grading program, it is important to establish a multiyear baseline. Patients who are progressing well in treatment tend to be finished by the time the current class graduates, and the problem patients are transferred. Because long treatment times are associated with diminished clinical outcomes, it is often in the best interest of the uncooperative patient to terminate treatment rather than extend active mechanics in an attempt to achieve a better result.

    Functional Capacity Evaluations (FCE's) are used within the occupational rehabilitation arena with the aim of assessing an individual's functional abilities in relation to work tasks. Therapists use a variety of different FCE's, both standardized and non standardized. This study aimed to investigate therapists' views on the clinical utility of FCE's in general and to identify if these differed between professional groups. A cross sectional study design was used. Health professionals who conduct FCE's and who worked for WorkCover accredited rehabilitation providers in NSW were surveyed. Surveys were returned from 79 participants working for 65 different rehabilitation providers. Of those who replied, 82\\% (n=63) were occupational therapists, 13% (n=10) physiotherapists and 5% (n=5) exercise physiologists. The mean years of professional experience was 10.9 years and the mean years of FCE experience was 5.3 years. Data were analyzed using STATA [v8.0] and the clinical utility of FCE's was considered relating to: usefulness & relevance; adaptability and flexibility; therapist perceived requirements and issues in practice. No differences were found related to the clinical utility of FCE's between professional groups or years of professional experience. The results suggest consistency and similarities in how FCE's are currently used in practice across NSW (Australia). Limitations of this study and areas for further research are suggested.

    Abstract The National Center for Advancing Translational Sciences (NCATS), a part of the National Institutes of Health, currently funds the Clinical and Translational Science Awards (CTSAs), a national consortium of 61 medical research institutions in 30 states and the District of Columbia. The program seeks to transform the way biomedical research is conducted, speed the translation of laboratory discoveries into treatments for patients, engage communities in clinical research efforts, and train a new generation of clinical and translational researchers. An endeavor as ambitious and complex as the CTSA program requires high‐quality evaluations in order to show that the program is well implemented, efficiently managed, and demonstrably effective. In this paper, the Evaluation Key Function Committee of the CTSA Consortium presents an overall framework for evaluating the CTSA program and offers policies to guide the evaluation work. The guidelines set forth are designed to serve as a tool for education within the CTSA community by illuminating key issues and practices that should be considered during evaluation planning, implementation, and utilization. Additionally, these guidelines can provide a basis for ongoing discussions about how the principles articulated in this paper can most effectively be translated into operational reality.

    Evaluation of the headache patient in the outpatient clinic and emergency department (ED) has different focuses and goals. The focus of this paper is to review the evaluation of patients in both settings with mention of evaluation in the pediatric and pregnant patient population.  The patient's history should drive the practitioner's decision and evaluation choices. We review recommendations made by the American Board of Internal Medicine and American Headache Society through the Choosing Wisely Campaign, which has an emphasis on choosing the right imaging modality for the clinical situation and elimination/prevention of medication overuse headache, as well as the US Headache Consortium guidelines for migraine headache. We will also review focusing on ED evaluation of the pediatric patient and pregnant patient presenting with headache. At the end of the review we hope to have provided you with a framework to think about the headache patient and what is the appropriate test in the given clinical setting in order to ensure that the patient gets the right diagnosis and is set on a path to the appropriate management plan. © 2015 American Headache Society.

    Traveller's diarrhea is the most common tourist's disease in the tropics. Therefore epidemiological data for the evaluation of factors influencing the attack rates and the severity of the disease are being required. This paper deals with the data of 1058 Austrian tourists travelling to warm climate countries. 47.3% of all travellers suffered from an episode of traveller's diarrhea during their stay. However, it could be evaluated that besides the destination seasonal influences were very important. Factors like individual hygiene and accommodation did not influence the attack rates. Age and environmental conditions, however, did partially influence the frequency of diarrhea. Furthermore, additional symptoms were interpreted and it could be seen that suspected heterogenicity of etiology leads to a similar pattern of clinical symptoms. Clinical evaluation proves that traveller's diarrhea is commonly not severe, but due to the incidence and duration of the disease it is a major health problem in modern tourism.

    Background: There is a low incidence of posterior instability which is present in only 2% to 10% of all unstable shoulders. The posterior instable shoulder includes different manifestations like fixed dislocation, recurrent subluxation or dislocation. Methods: Research and online content related to posterior instability is reviewed. Natural history, clinical evaluation and imaging are described. Results: An awareness of the disorder, together with a thoughtful evaluation, beginning with the clinical history, usually leads to proper diagnosis. An appropriate physical exam, taking in account hyperlaxity and specific tests for posterior instability should be done. Conclusion: Posterior shoulder instability is an uncommon condition and is challenging to diagnose. There is not a single injury that is responsible for all cases of recurrent shoulder dislocation or subluxation, and the presence of soft tissue lesions or bone alterations should be evaluated, with the use of adequate simple radiology and multiplanar imaging.

    Purpose The purpose of this paper is to present lessons learnt through the development of an evaluation framework for a clinical redesign programme - the aim of which was to improve the patient journey through improved discharge practices within an Australian public hospital. Design/methodology/approach The development of the evaluation framework involved three stages - namely, the analysis of secondary data relating to the discharge planning pathway; the analysis of primary data including field-notes and interview transcripts on hospital processes; and the triangulation of these data sets to devise the framework. The evaluation framework ensured that resource use, process management, patient satisfaction, and staff well-being and productivity were each connected with measures, targets, and the aim of clinical redesign programme. Findings The application of business process management and a balanced scorecard enabled a different way of framing the evaluation, ensuring measurable outcomes were connected to inputs and outputs. Lessons learnt include: first, the importance of mixed-methods research to devise the framework and evaluate the redesigned processes; second, the need for appropriate tools and resources to adequately capture change across the different domains of the redesign programme; and third, the value of developing and applying an evaluative framework progressively. Research limitations/implications The evaluation framework is limited by its retrospective application to a clinical process redesign programme. Originality/value This research supports benchmarking with national and international practices in relation to best practice healthcare redesign processes. Additionally, it provides a theoretical contribution on evaluating health services improvement and redesign initiatives.

    Lamivudine, telbivudine, and entecavir are the first-line drugs covered by the Taiwan National Health Insurance as 3-year treatments for patients with chronic hepatitis B virus (HBV), but the optimal treatment duration of each remains unclear. We aimed to detect HBV treatment-cessation durability, and compare the predictors in patients with and without clinical relapse. In this retrospective cohort study, 210 patients with chronic HBV who tested hepatitis B e-antigen positive or hepatitis B e-antigen negative were treated for 3 years with a nucleos(t)ide analogue. Of these, 102 patients continued therapy after 3 years, while 88 patients stopped treatment and were followed for 1 year due to financial difficulties. Efficacy was assessed in terms of alanine aminotransferase (ALT) level normalization, HBV DNA clearance, virus breakthrough, clinical relapse, and liver decompensation. The durability predictors were evaluated by host factors, HBV DNA, and drug differences. Eighty patients (14 on lamivudine, 19 on telbivudine, and 47 on entecavir) were recruited. There was no difference in clinical-relapse rate among lamivudine, telbivudine, and entecavir (35.7% vs. 36.8% vs. 31.9%, respectively; p = 0.916), and liver decompensated hepatitis was absent. In baseline clinical characteristics, there were no differences between the clinical-relapse and nonrelapse groups in age, sex, cirrhosis, prior treatment, HBV DNA, pretreatment ALT, or hepatitis B e-antigen (HBeAg). The mean 3(rd) year serum ALT level differed significantly between clinical-relapse and nonrelapse patients (37.5 U/L vs. 27.7 U/L, respectively; p = 0.044). The 3-year nucleos(t)ide analogue off-treatment in patients with chronic HBV delivered according to the Taiwan National Health Insurance guidelines had an overall 33.8% 1-year clinical-relapse rate without any decompensated hepatitis flare-ups.

    Studies have consistently evidenced the positive clinical, economic, and humanistic benefits of pharmacist-directed patient care in a variety of settings. Given the vast differences in clinical outcomes associated with evaluated clinical pharmacy services (CPS), more detail as to the nature of the CPS is needed to better understand observed differences in economic outcomes. With the growing trend of outpatient pharmacy services, these economic evaluations serve as viable decision-making tools in choosing the most effective and cost-effective pharmacy programs. We previously conducted three systematic reviews to evaluate the economic impact of CPS from 1988 to 2005. In this systematic review, our objectives were to describe and evaluate the quality of economic evaluations of CPS published between 2006 and 2010, with the goal of informing administrators and practitioners as to their cost-effectiveness. We searched the scientific literature by using the Medline, International Pharmaceutical Abstracts, Embase, and Cumulative Index to Nursing and Allied Health Literature databases to identify studies describing CPS published from 2006 to 2010. Studies meeting our inclusion criteria (original research articles that evaluated CPS and described economic and clinical outcomes) were reviewed by two investigators. Methodology used, economic evaluation type, CPS setting and type, and clinical and economic outcome results were extracted. Results were informally compared with previous systematic reviews. Of 3587 potential studies identified, 25 met inclusion criteria. Common CPS settings were hospital (36%), community (32%), and clinic or hospital-based ambulatory practices (28%). CPS types were disease state management (48%), general pharmacotherapeutic monitoring (24%), target drug programs (8%), and patient education (4%). Two studies (8%) listed CPS as medication therapy management. Costs were evaluated in 24 studies (96%) and sufficiently described in 13 (52%). Clinical or

    This randomized controlled trial compared the survival of glass fibre and cast metal dental posts used to restore endodontically treated teeth with no remaining coronal wall. Fifty-four participants (45 women) and 72 teeth were evaluated during a follow-up period of up to 3 years. Teeth were randomly allocated to the glass-fibre and cast-metal post groups. All teeth were restored with single metal-ceramic crowns. Survival probabilities were analyzed using Kaplan-Meier statistics (p≤0.05). The 3-year recall rate was 92.3% and the survival rates of glass fibre and cast metal posts were similar (97.1% and 91.9%, respectively; p=0.682). Four failures were observed: two glass fibre posts in a premolar and anterior tooth debonded, one glass fibre post in a premolar debonded in association with root fracture, and one root fracture occurred in a molar with a cast metal post. Glass fibre and cast metal posts showed similar clinical performance in teeth with no remaining coronal wall after 3 years. Posts are used to restore most endodontically treated teeth with no remaining coronal wall. This randomized controlled trial, one of few to compare glass fibre and cast metal posts in such teeth, showed that post type did not significantly influence the survival of restorations. These results can help dentists respond to the important question of how best to rehabilitate endodontically treated teeth with no remaining coronal wall. Copyright © 2014 Elsevier Ltd.

    The objective of this 3-year prospective study was to evaluate a new titanium dental implant system and to identify any mechanical concerns or deficiencies in its design. One periodontist placed 78 single-tooth implants in 59 subjects. One restorative dentist using one dental laboratory fabricated all of the crowns. Each patient then was seen eight times by the authors for clinical, radiographic, and laboratory testing. One of the 78 implants failed to integrate and was removed. There were no structural failures per se, although six of the cemented crowns and six of the restorative posts and cores (abutments) became loose. On a few occasions, the emergence profile was esthetically or functionally unsatisfactory. The manufacturer introduced changes in design and created an adjustable torque wrench, a torque-adjusting beam scale, and die replicas of the abutment posts in response to the identified concerns. The clinical trial helped in the development of an implant system that is user friendly, cost effective, and able to withstand parafunctional forces in the absence of antirotational features.

    The objective of this prospective study was to determine the impact of early literacy anticipatory guidance (AG) with provision of books on language development in 3-year-olds in an early literacy program at a University-affiliated inner-city pediatric clinic. The Peabody Picture Vocabulary Test (PPVT-III) and the Expressive One Word Picture Vocabulary Test (EOWPVT-R) were administered to 33-39-month-old children exposed to an early literacy program, which included AG and provision of an age-appropriate book at each well-child visit starting at 2 months old. Children with developmental delays were excluded. Parental surveys on literacy and demographic data were obtained. Univariate and multivariate analyses were performed. Sixty-four children were evaluated; 88% African American, 89% Medicaid recipients. Fifty-eight percent of families reported family-centered literacy orientation. The PPVT-III scores directly correlated with the number of AG visits with book given x number of books purchased (r2 = 0.025, p = 0.0006). Higher scores in EOWPVT-R were predicted by race and the number of visits with books given x number of books purchased (r2 = 0.182, p = 0.0009). All families reported reading together, half reporting positive family-centered literacy. Given the same number of books purchased for each child, the outcome scores were higher the greater the number of clinic visits wherein AG included early literacy and provision of books.

    In response to increasing scientific evidence which indicates that ultraviolet radiation (UVR) is a potential threat to ocular health, Acuvue contact lenses (Vistakon, Johnson & Johnson Vision Products Inc., Jacksonville, Florida) have been developed which incorporate an ultraviolet (UV) blocker within the lens polymer. Data are presented for the first clinical evaluation of Acuvue lenses with UV blocking characteristics. A double-masked, multicenter, prospective clinical trial involving 94 subjects was conducted. The study followed a randomized, parallel group design and consisted of 3 months of daily wear with two-weekly lens replacement. Two thirds of the subjects (61) wore the test lenses (Acuvue with UV blocker) and the remaining subjects (33) wore conventional Acuvue lenses (without UV blocker). Biomicroscopic evaluations indicated that the performance of the test and control lenses was clinically similar. No clinically relevant differences between the test and control lenses were noted in the subjective assessments of vision, comfort, or handling. In addition, no differences were shown for surface deposition, lens durability, visual acuity, and subjective symptoms. The study findings indicate that the addition of a UV blocker to Acuvue contact lenses has been achieved without affecting daily wear clinical performance. Because there is increasing evidence to suggest that the ocular tissues may be damaged by UVR, it is prudent for eye care practitioners to prescribe contact lenses that offer the benefits of both regular replacement and UV protection.

    Use of clinical simulation in the design and evaluation of eHealth systems and applications has increased during the last decade. This paper describes a methodological approach for using clinical simulations in the design and evaluation of clinical information systems. The method is based on experiences from more than 20 clinical simulation studies conducted at the ITX-lab in the Capital Region of Denmark during the last 5 years. A ten-step approach to conducting simulations is presented in this paper. To illustrate the approach, a clinical simulation study concerning implementation of Digital Clinical Practice Guidelines in a prototype planning and coordination module is presented. In the case study potential benefits were assessed in a full-scale simulation test including 18 health care professionals. The results showed that health care professionals can benefit from such a module. Unintended consequences concerning terminology and changes in the division of responsibility amongst healthcare professionals were also identified, and questions were raised concerning future workflow across sector borders. Furthermore unexpected new possible benefits concerning improved communication, content of information in discharge letters and quality management emerged during the testing. In addition new potential groups of users were identified. The case study is used to demonstrate the potential of using the clinical simulation approach described in the paper.

    A clinical tympanic thermometer was evaluated. In vitro it was found to be accurate over the temperature range 28 degrees C to 40 degrees C. Clinical assessment was made during the cooling and rewarming phases of patients undergoing surgery with the aid of cardiopulmonary bypass and compared with the results obtained with an Ellab thermocouple thermometer. It was also used in patients in the intensive care unit in whom core temperature was being measured using the thermistor incorporated in a pulmonary artery catheter. The infrared thermometer was found to be accurate, rapidly responding and easy to use.

    Background: This systematic review evaluated the effectiveness of distraction for reducing infant distress during vaccinations in young children aged 0 to 3 years. Design/Methods: Database searches identified relevant randomized and quasi-randomized controlled trials. Three separate clinical questions related to variants of the psychological strategy of distraction (directed video; directed toy; nondirected toy) were pursued. Distress was identified as the critical outcome to assess the benefits of distraction and extracted from relevant trials. Distress was analyzed by phase of procedure (distress preprocedure; distress acute; distress recovery; idiosyncratic phases based on some or all of the 3 aforementioned phases). Results: Ten studies were included in the review. Significant results are presented herein. For directed video distraction, moderate quality evidence suggested that distress was lowered in the treatment group standardized mean difference (SMD −0.68 lower [95% confidence interval (CI), −1.04 to −0.32]) for the acute+recovery phase as well as the preprocedure phase (SMD −0.49 lower [95% CI, −7.6 to −0.22]). For directed toy distraction, the analysis of low-quality evidence for a combined preprocedure+acute+recovery phase of distress (analysis n=81), suggested that distress was lowered in the treatment group (SMD −0.47 lower [95% CI, −0.91 to −0.02]). An effect for nondirected toy distraction was also seen, analyzing very–low-quality evidence, for the acute distress phase (n=290; SMD −0.93 lower [95% CI, −1.86 to 0.00]). Conclusion: Generally low-quality to very–low-quality evidence suggests that there may be an effect of directed (toy and video) and nondirected toy distraction for children aged 0 to 3 years, for certain phases of the vaccination.

    A pulpotomy is the therapy for management of pulp exposures due to caries in symptom-free primary molars. The aim was to longitudinally compare the relative effectiveness of the Er:YAG laser, calcium hydroxide and ferric sulphate techniques with dilute formocresol in retaining symptom-free molars. Two hundred primary molars in 107 healthy children were included and randomly allocated to one technique. The treated teeth were blindly reevaluated after 6, 12, 18, 24 and 36 months. Descriptive data analysis and logistic regression analysis accounting for multiple observations per patient by generalised estimating equation were used. Additionally, various influences including tooth type, upper and lower jaws, type of anaesthesia, operator and the final restoration on treatment success were evaluated (Wald chi-square test). After 36 months, the following total (considering clinical and clinically symptom-free radiographic failures) and clinical success rates were determined (in percent): Formocresol 72 (92), laser 73 (89), calcium hydroxide 46 (75), ferric sulphate 76 (97). No significant differences were detected between formocresol and any other technique after 36 months. However, the odds ratio of failure appeared to be three times higher for calcium hydroxide than for formocresol. No significant differences in total success rates were seen regarding the aforementioned influencing clinical parameters. The correct diagnosis of the pulpal status, bleeding control and the specific technique are highly important for long-term success of pulpotomies in primary molars. According to the presented long-term data, pulpotomies using ferric sulphate revealed the best treatment outcome among the used techniques, while calcium hydroxide resulted in the lowest success rates after 3 years. Therefore, we can recommend ferric sulphate for easy and successful treatment of primary molars with caries-exposed pulps.

    Foot posture involves the integration of sensory information from the periphery of the body. This information generates precise changes through fine adjustments that compensate for the continuous, spontaneous sway of the body in the standing position. Orthopedic insoles are one of the therapeutic resources indicated for assisting in this process. Evaluation of these podal influences, by clinical examination and/or the assistance of baropodometry becomes crucial. Thus, the aim of the present study was determine the combination of the components of orthopedic insoles using two different evaluation methods. Forty healthy female volunteers between 18 and 30 years participated in the study. The volunteers were submitted to two different evaluations: clinical analysis and baropodometry. During the exams, different insole components were tested. The statistical analysis of the two evaluations revealed differences regarding the normalization of posture following the application of the insole components and in the determination of the combination of these components. The findings suggest that the clinical analysis is a fast and accurate method for determining the immediate benefits of the postural insole components and is therefore the more indicated method for the evaluation of foot posture, but does not present a concrete foundation to differentiate it with respect to baropodometric evaluation in the assessment and diagnosis of foot posture, however, a greater difficulty was encountered in achieving posture normalization when using information obtained through baropodometry.

    Three to 12 evaluations of clinical performance using the mini-clinical evaluation exercise (Mini-CEX) (n = 124) or direct observation of procedural skills (DOPS) (n = 21) were performed on 27 trainees working in an NHS neurology department. The communications/ counselling skills subdomain was scored in 64 evaluations. For Mini-CEX the focus was on gathering data (22%), diagnosis (31%), management (34%) and counselling (7%) (focus not recorded in 6%). For DOPS, lumbar puncture was the most common evaluated procedure (57%). Mini-CEX evaluations lasted 23.8 minutes (10.6) (mean, sd) and DOPS 25.9 minutes (12.6). Mini-CEX scores for overall competence and communication skills were mean 5.99 (sd 0.95, range 4-8) and 5.98 (sd 1.21, range 3-9) and for DOPS 5.71 (sd 0.90, range 4-8) both on scales of 1 to 9. Overall trainee competence and communication scores increased with year of training (p < 0.001, p < 0.004 univariate analysis). Assessors undertook up to three or four assessments in a session. Assessors and trainees considered that the observation and feedback had been 'very' or 'quite' useful in providing a relevant element of assessment. These assessments were feasible and useful in a neurology department and provided some evidence for increasing performance with trainee seniority. More assessor time (approximately one hour) than trainee time (24-26 min) was needed for each assessment undertaken.

    Objective Clinicians’ attention is a precious resource, which in the current healthcare practice is consumed by the cognitive demands arising from complex patient conditions, information overload, time pressure, and the need to aggregate and synthesize information from disparate sources. The ability to organize information in ways that facilitate the generation of effective diagnostic solutions is a distinguishing characteristic of expert physicians, suggesting that automated systems that organize clinical information in a similar manner may augment physicians’ decision-making capabilities. In this paper, we describe the design and evaluation of a theoretically driven cognitive support system (CSS) that assists psychiatrists in their interpretation of clinical cases. The system highlights, and provides the means to navigate to, text that is organized in accordance with a set of diagnostically and therapeutically meaningful higher-level concepts. Methods and Materials To evaluate the interface, 16 psychiatry residents interpreted two clinical case scenarios, with and without the CSS. Think-aloud protocols captured during their interpretation of the cases were transcribed and analyzed qualitatively. In addition, the frequency and relative position of content related to key higher-level concepts in a verbal summary of the case were evaluated. In addition the transcripts from both groups were compared to an expert derived reference standard using latent semantic analysis (LSA). Results Qualitative analysis showed that users of the system better attended to specific clinically important aspects of both cases when these were highlighted by the system, and revealed ways in which the system mediates hypotheses generation and evaluation. Analysis of the summary data showed differences in emphasis with and without the system. The LSA analysis suggested users of the system were more “expert-like” in their emphasis, and that cognitive support was more effective in the

    Summary Filoviruses are the etiological agents of two human illnesses: Ebola virus disease and Marburg virus disease. Until 2013, medical countermeasure development against these afflictions was limited to only a few research institutes worldwide as both infections were considered exotic due to very low case numbers. Together with the high case-fatality rate of both diseases, evaluation of any candidate countermeasure in properly controlled clinical trials seemed impossible. However, in 2013, Ebola virus was identified as the etiological agent of a large disease outbreak in Western Africa including almost 30,000 infections and more than 11,000 deaths, including case exportations to Europe and North America. These large case numbers resulted in medical countermeasure development against Ebola virus disease becoming a global public-health priority. This review summarizes the status quo of candidate vaccines against Ebola virus disease, with a focus on those that are currently under evaluation in clinical trials. PMID:27160784

    The goal in the setup of the clinical evaluation of the PACSystem in the University Hospital Utrecht (UUH) is to realize such a presentation of images, coupled to other patient information, that radiologists and applicants can make diagnoses more flexible, faster and more fruitful. Moreover we try to get insight in the way a PACSystem can solve the problems regarding the contempory way of working with respects to diagnoses and image information; i. e. problems related to archiving and loaning of pictures, which may lead to loss and long searching times, problems with respect to room for archive, the high costs of photographic material and the impossibility of post processing on film. For the evaluation studies the following points are of importance. a. the storage of digitized image information on magnetic disc and optical disc (DOR). Direct digital input is coming from e. g. CT. While conventional films are digitised with a scanner/digitizer (MARSCAN). The image information can be seen on several monitors at the same time (multi access), i.e via MARVIEW in the digital reading room and a viewing station on the clinical ward. b. A coupling between the Hospital Information System (BAZIS) and PACS will be realized. c. The MARVIEW station offers several forms of image manipulation. In principle there is chosen for a complete PACS situation, that is to say that all information and procedures relating to the patients of a specific ward are manipulated up in the PACSystem. This specific ward is a clinical internal department and has fifteen beds. The data of this ward are compared to two comparable wards before and after installation of the PACSystem. Crucial is that in this situation we deal with a real operating clinical ward. To evaluate the effects of the introduction of such a PACSystem on diagnoses and organisation, a number of sub-projects are carried out in joint venture between the University Hospital Utrecht, BAZIS and PHILIPS.

    Technology design is a complex task, and acceptability is enhanced when usability is central to its design. Evaluating usability is a challenge for purchasers and developers of technology. We have developed a framework for testing the usability of clinical monitoring technology through literature review and experience designing clinical monitors. The framework can help designers meet key international usability norms. The framework includes these direct testing methods: thinking aloud, question asking, co-discovery, performance and psychophysiological measurement. Indirect testing methods include: questionnaires and interviews, observation and ethnographic studies, and self-reporting logs. Inspection, a third usability testing method, is also included. The use of these methods is described and practical examples of how they would be used in the development of an innovative monitor are given throughout. This framework is built on a range of methods to ensure harmony between users and new clinical monitoring technology, and have been selected to be practical to use.

    Group sequential stopping rules are often used as guidelines in the monitoring of clinical trials in order to address the ethical and efficiency issues inherent in human testing of a new treatment or preventive agent for disease. Such stopping rules have been proposed based on a variety of different criteria, both scientific (e.g. estimates of treatment effect) and statistical (e.g. frequentist type I error, Bayesian posterior probabilities, stochastic curtailment). It is easily shown, however, that a stopping rule based on one of these criteria induces a stopping rule on all other criteria. Thus, the basis used to initially define a stopping rule is relatively unimportant so long as the operating characteristics of the stopping rule are fully investigated. In this paper we describe how the frequentist operating characteristics of a particular stopping rule might be evaluated to ensure that the selected clinical trial design satisfies the constraints imposed by the many different disciplines represented by the clinical trial collaborators.

    Chewable tablets containing low dosage flouride content were prepared using two varities of celluloses and their in vitro parameters were evaluated. An eighteen month clinical trial revealed that both these formulations were effective in controlling the caries. However, ethyl cellulose is proved to be superior to methylcellulose as a controlled release matrix material in controlling caries. Thus this study recommends ethylcellulose matrix tablets containing low flouride content is an efficacious and cost effective drug device in controlling dental caries.

  10. An evaluation of the role of the clinical education facilitator.

    2006-02-01

    The objective of the study was to identify whether clinical education facilitators made a difference to the learning experiences of nurses in a large teaching hospital. Strategies for enabling continuous professional development are well established in health care organizations as key components of approaches to lifelong learning. The benefits of continuous professional development include the maintenance of high standards of care, the improvement and development of services, ensuring the competency of all nursing staff and guaranteeing the accountability of nurses for their actions. The role of clinical education facilitator is relatively new and little evaluation of this role has been undertaken. This study highlights important issues to be considered in developing a 'learning culture' in a hospital organization, through the adoption of such roles as clinical education facilitators. Whilst the roles have had an important function in the active coordination of learning activities in the hospital, there is little evidence of the role directly impacting on the learning culture of clinical settings. Learning mechanisms have been identified. The results of this evaluation can be subjected to further testing through ongoing evaluation of the outcomes arising from the learning mechanisms in place. Given the emphasis on work-based learning and continuing professional development in health care, then this ongoing evaluation can yield important information about future directions for nurse education. The study highlights the importance of supported learning in the workplace. However, more importantly, it identifies the need for a culture of professional practice to be developed in order to sustain learning in practice. Classroom-based learning alone, cannot create a culture of development in nursing and there is thus a need for models of work-based learning to be integrated into practice environments.

    Composite resins are still outperformed by amalgams in the clinical practice with secondary caries and fractures being their most common failures. A material that suffers less polymerization shrinkage might improve the clinical performance of composite resins. To evaluate the clinical performance of a low-shrink silorane-based composite resin (Filtek LS Low Shrink Posterior Restorative, 3M ESPE, St. Paul, MN, USA) in comparison with a methacrylate-based composite resin (Tetric EvoCeram, Ivoclar Vivadent, Schaan, Principality of Liechtenstein) over time. Candidates in need of Class II composite resin restorations participated in this randomized controlled clinical trial. Those were 25 female and six male subjects with average age of 44.3 ± 12.7 years. Participants received 82 restorations, being 54 in premolars and 28 in molars. Procedures, which included the restoration of primary caries lesions or replacement of failing restorations, were done using modified preparations with no bevels or additional retention. Restorations were placed using Filtek LS (and dedicated self-etch adhesive) or Tetric EvoCeram (with AdheSE, Ivoclar Vivadent), following manufacturers' instructions. Incremental placement technique was applied and the restorations were immediately finished. Follow-up evaluations occurred at six, 12, 24, and 36 months and were done using the Fédération Dentaire Internationale criteria. Statistical analysis was performed using generalized estimating equations. The recall rate at 36 months was 89%. All interaction terms were not significant. Filtek LS performs as well as Tetric EvoCeram performs in the clinical setting at 36 months. The silorane-based composite resin Filtek LS and the conventional methacrylate-based composite resin Tetric EvoCeram performed similarly well in posterior restorations over at least 36 months of clinical service. © 2013 Wiley Periodicals, Inc.

    The results of kidney transplantation have improved significantly in the last decade with patient and graft survival rates that range from 92% to 95%. We analyzed the clinical results in the last 100 consecutive patients with a follow-up of 6-42 months at our institution. We also made a general evaluation of the patients before surgery as candidates for transplantation and divided them into 3 groups (good, moderate, and poor). We had 8 living donors and 92 cadaveric kidney transplantation cases. Principal cause of donor death was cerebrovascular disease accounting for 64%. Mean age of recipients was 55.1 ± 12.9 years with a total of 65 males. Currently there are 96 functioning allografts. During this 3-year period, 2 patients suffered graft loss and 2 patients died with a functioning allograft. We studied whether there were statistically significant differences in renal function (Modification of Diet in Renal Disease Study Equation [MDRD]) at 12 months and at last visit with respect to the evaluation of recipient as candidate for renal transplantation. Our observations suggest great improvement of early results of renal transplantation in recent years, including complex cases. In this 3-year period we had a patient survival rate of 98% and a graft survival rate of 96% of cases. Further dedicated prospective studies that aim to evaluate or to propose possible recipient-related predictors for kidney transplantation outcomes in different populations are needed.

    1996-01-01

    For patients with neurological damage of the central nervous system, such as that due to cerebrovascular accident (CVA), standing balance training is a critical therapeutic procedure to be undertaken before walking and self-care training. The identification and characterization of neurological disorder in postural steadiness will enhance our understanding of the postural control system, and help to identify patients at risk of falls in the CVA population. This paper discusses the design and clinical evaluation of a new biofeedback training device for static (postural steadiness) performance of the standing balance system. The device includes a height adjustable standing table, an instrumented force sensing platform, an on-line weight bearing audio/visual biofeedback system, a postural correction mirror, and a belt suspension system for the upper extremities. A quantitative evaluation protocol of bilateral asymmetries in weight distribution and postural sway to characterize standing balance with the force sensing platform is discussed. Finally, the clinical evaluation results of sixty patients with hemiplegia from acute stroke for a period of four weeks are discussed. With this economic standing training device, the static standing steadiness can be trained effectively through weight bearing biofeedback and a postural correction mirror in the clinical and home caring environments.

    Background In prior work laboratory-based measures of hip motor function and ankle proprioceptive precision were critical to maintaining unipedal stance and fall/fall-related injury risk. However, the optimal clinical evaluation techniques for predicting these measures are unknown. Objective To evaluate the diagnostic accuracy of common clinical maneuvers in predicting laboratory-based measures of frontal plane hip rate of torque development (HipRTD) and ankle proprioceptive thresholds (AnkPRO) associated with increased fall risk. Design Prospective, observational study. Setting Biomechanical research laboratory. Participants Forty-one older subjects (age 69.1 ± 8.3 years), 25 with varying degrees of diabetic distal symmetric polyneuropathy and 16 without. Assessments Clinical hip strength was evaluated by manual muscle testing (MMT) and lateral plank time (LPT), defined as the number seconds the laterally lying subject could lift hips from the support surface. Foot/ankle evaluation included Achilles reflex, and vibratory, proprioceptive, monofilament, and pinprick sensations at the great toe. Main Outcome Measures HipRTD, abduction and adduction, using a custom whole-body dynamometer. AnkPRO determined with subjects standing using a foot cradle system and a staircase series of 100 frontal plane rotational stimuli. Results Pearson correlation coefficients (r) and receiver operator characteristic (ROC) curves revealed that LPT correlated more strongly with HipRTD (r/p = .61/<.001 and .67/<.001, for abductor/adductor, respectively) than did hip abductor MMT (r/p = .31/.044). Subjects with greater vibratory and proprioceptive sensation, and intact Achilles reflexes, monofilament, and pin sensation had more precise AnkPRO. LPT of < 12 seconds yielded a sensitivity/specificity of 91%/80% for identifying HipRTD < .25 (body size in Newton-meters), and vibratory perception of < 8 seconds yielded a sensitivity/specificity of 94%/80% for the identification of AnkPRO > 1

    There is a growing consensus favouring the development, advancement, and implementation of a competency-based approach for psychology training and supervision. There is wide recognition that skills, attitude-values, and relationship competencies are as critical to a psychologist's competence as are knowledge capabilities, and that these key competencies are best measured during placements, leaving the clinical supervisor in an unparalleled position of advantage to provide formative and summative evaluations on the supervisee's progression towards competence. Paradoxically, a compelling body of literature from across disciplines indicates that supervisor ratings of broad domains of competence are systematically compromised by biases, including leniency error and halo effect. The current paper highlights key issues affecting summative competency evaluations by supervisors: what competencies should be evaluated, who should conduct the evaluation, how (tools) and when evaluations should be conducted, and process variables that affect evaluation. The article concludes by providing research recommendations to underpin and promote future progress and by offering practice recommendations to facilitate a more credible and meaningful evaluation of competence and competencies.

    The aim of the study was to evaluate the anatomical and functional outcomes of modified laparoscopic sacrocolpopexy (MLSC) for the treatment of advanced pelvic organ prolapse (POP). From May 2009 to September 2012, a consecutive prospective observational study of 30 participants was conducted to evaluate MLSC as a treatment for symptomatic advanced POP at Peking Union Medical College Hospital. The Pelvic Organ Prolapse Quantification (POP-Q) classification was used to determine the POP stage. Validated tools were used to evaluate symptoms (Pelvic Floor Distress Inventory, PFDI-20) and sexual function (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, PISQ-12). Measurements were recorded preoperatively and then at 3 months and yearly after surgery. We compared the follow-up results with the preoperative data. All participants completed a 3-year clinical follow-up routine. The anatomical results at 3 months showed significant improvements (P < 0.05) compared with the preoperative results based on the POP-Q measurements. This improvement remained significant after 3 years (P < 0.05). The anatomical cure rate was 100% and 96.7% at 3 months and 3 years after surgery, respectively. Pelvic floor function remained significantly improved after surgery compared with preceding surgery (P < 0.05) according to the following measures: PFDI-20 (106.2 vs 36.0), Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6, 47.9 vs 13.7), Colorectal-Anal Distress Inventory-8 (CRADI-8, 29.2 vs 9.2), and Urinary Distress Inventory-6 (UDI-6, 29.2 vs 13.2). The participants maintained a high level of sexual function (PISQ-12: 29.0 vs 35.1, P < 0.05). One case of mesh exposure (3.3%) and two cases of de novo dyspareunia (8.7%) were observed. MLSC seems to be a safe and effective procedure that achieves good long-term anatomical and functional results.

    Pityriasis rosea (PR) is a common, acute, self-limiting inflammatory skin disease. It can easily be recognized with its typical clinical presentation. However, unusual clinic presentations can cause difficulty in diagnosis. Up to now, not many atypical forms are reported. To determine the clinical characteristics of patients with atypical pityriasis rosea. A total of 27 cases, diagnosed as atypical PR by clinical and/or histopathological examination and applied to the outpatient clinic of dermatology department between the years 2007 and 2015 were analyzed retrospectively. The ages of patients ranged from 2 to 59 years. Of these patients, 15 (55.6%) were male and 12 (44.4%) were female. The male-to-female ratio was 5-4. Five patients had papular, four patients had purpuric, three patients had vesicular, two patients had follicular, one patient had erythema multiforme-like and one patient had eczematous drug-induced atypical form of pityriasis rosea. There were 12 cases of localized, two cases of segmental pityriasis rosea. Four of the localized forms also had atypical morphology. Histopathological evaluation was required for diagnosis in 12 (44.4%) patients. PR can appear in many different uncommon forms. Localization and skin rush can be misleading and diagnosis can be compelling.

    Background: Clinical attachment level is the most frequently used and acceptable parameter in monitoring periodontal status in diseased individual and denotes patterns of periodontal destruction. Awareness of root morphology and the condition of the periodontal tissues is essential for reliable periodontal pocket probing and for effective debridement of root surfaces. Clinically, it is challenging to observe exact nature of complex periodontal attachment loss. The aim of the present study was to evaluate patterns of periodontal destruction based on vertical and horizontal attachment loss. Materials and Methods: A total of 200 extracted teeth were obtained from chronic periodontitis patients. Prior to extraction, clinical measurements were recorded and after extraction, the teeth were stained with crystal violet. Root length, vertical and horizontal attachment loss were measured using digital caliper. Results: There was a significant difference between clinical attachment level and vertical attachment loss for both maxillary and mandibular teeth. Mean vertical attachment loss varied between 5.17 mm and 9.17 mm. Interproximal surfaces exhibited statistically significant vertical attachment loss in both maxillary and mandibular dentition. Results indicated that vertical attachment loss was more severe with teeth belonging to the anterior sextant whereas the horizontal attachment loss was more pronounced with posterior teeth. Conclusion: Both vertical and horizontal attachment loss were observed in all periodontally involved teeth. There was a difference in clinical measurements and actual periodontal status denoted by postextraction staining. These findings have an impact on determining the prognosis and appropriate treatment plan for patients. PMID:27143828

The permanent first molars (PFMs) of 50 children, 7-13 years of age (mean age: 8.9 +/- 1.3 years), were sealed with a split-mouth design. Fissure sealants applied to the PFMs according to the manufacturer's recommendations by one pediatric dentist. Clinical evaluation of the sealants was carried out to record retention, marginal integrity and presence of caries at 6, 12, 18 and 24 months after placement by the other pediatric dentist. Kaplan-Meier survival analysis and Cox's regression models were used to estimate the probability of two sealants success. Alpha and Bravo retention rates at the end of follow-up were 13% and 80% for Fuji VII and 3% and 83% for AS, respectively. For retention and marginal integrity between fissure sealants was found similar survival rates (p > 0.05). After 24 months, presence of caries was 16% for Fuji VII and 32% for AS (p < 0.05). Fuji VII and AS exhibited similar retention and marginal integrity during 24 months. However Fuji VII was showed better results than AS for caries preventive effect. Consequently, Fuji VII sealants may be a better choice for preventing occlusal caries.

    This study evaluated the incidence of diabetic retinopathy (DR) over a 3-year period in a French population that was followed by OPHDIAT®, and assessed the clinical and biological risk factors associated with incident retinopathy. The studied patients were screened for DR during hospitalization for their annual diabetes check-up in the endocrinology department by two examinations three years apart. DR screening used the OPHDIAT® telemedical network, and the examination included clinical and biological data. A total of 254 patients were studied. At the 3-year follow-up, the incidence was 14.0%, (CI: 9.5-18.4%). Longer duration of diabetes and the presence of micro- or macroalbuminuria were significantly associated with incident retinopathy (P<0.05). Other potential risk factors were not statistically significantly related to DR progression, and only treatment with insulin showed a trend towards significance (P<0.20). This study provides the first French data on the incidence of DR, which was estimated after a 3-year follow-up at 14.0%. Longer duration of time from the onset of diabetes and higher baseline albuminuria were the only statistically significant risk factors found for the incidence of DR after our 3-year study. Nevertheless, microalbuminuria should be more widely used in ophthalmological practice in the assessment of DR, as is already the case for both blood pressure and HbA(1c).

    Cardiac patients may undergo a range of diagnostic examinations including angiography, echocardiography, nuclear medicine, x-ray, ECG and blood pressure measurement. Cine angiograms are reviewed at cardiac case conferences. Other data types are not typically exhibited due to the incompatibility of display devices. The aim of this study was to evaluate a workstation developed for multimodality reporting in cardiac case conferencing. A PC based system was developed as part of an EU project AMIE enabling all patient data to be viewed and manipulated on a large screen display using a high resolution video projector. The digital data was acquired using a variety of methods compatible with the systems involved. A technical evaluation of the projected imagery was performed by the grading of phantom test objects. A limited clinical evaluation was also performed whereby a panel of 10 consultant radiologists and cardiologists reported on angiography and x-ray images from 50 patients. Several months later the original data sets were reported and the result compared. Results of the clinical and technical evaluations indicate that the systems is satisfactory for the primary diagnosis of all data types with the exception of x-ray. The projected x-ray imagery is satisfactory for reference and teaching purposes.

    The purpose of this study was to evaluate the clinical success of and parental satisfaction with anterior pediatric zirconia crowns. A retrospective analysis of maxillary anterior pediatric zirconia crowns was performed. Crowns were evaluated for retention, gingival health, color match, contour, marginal integrity, and opposing tooth wear. Parental satisfaction regarding the esthetics of the crowns and parental perception of the impact of treatment on the child's appearance and oral health were evaluated by questionnaire. Fifty-seven crowns were evaluated in 18 children. Eight teeth were lost to exfoliation, three were extracted due to pathology, and two crowns debonded, leaving 44 available for examination. The average crown age at time of examination was 20.8 months. Sixteen crowns (36 percent) displayed gingival inflammation and color mismatch. No recurrent caries or opposing tooth wear was noted. Parents reported high satisfaction with the color, size, and shape of the crowns. The majority of parents reported that crowns improved the appearance and oral health of their child (78 percent and 83 percent, respectively). Eight-nine percent of parents reported that they would highly recommend these crowns. Zirconia crowns are clinically acceptable restorations in the primary maxillary anterior dentition. Parental satisfaction with zirconia crowns is high.

    Background Decreased scapulothoracic motion has been associated with various pathologies of the shoulder. Reliable and simple assessment methods of scapular mobility are, however lacking. The aim of this study was to evaluate the interrater reliability of four clinical tests to assess scapulothoracic motion in patients with a slightly restricted shoulder flexion. Methods A total of nineteen patients with a symptomatic slight restriction of shoulder flexion and twenty asymptomatic subjects were evaluated. The investigation consisted of four palpatory tests to assess scapulothoracic motion. A two-level rating scale (positive, negative) was utilised. Interrater reliability was evaluated using kappa coefficients. Results We found substantial to almost perfect (Kappa = 0.63-0.4) interrater reliability for the four tests. Conclusion Our study demonstrates that the four mobility tests of the shoulder are a reliable and simple instrument to assess patients with a slightly restricted shoulder flexion. Future studies should be conducted to evaluate the validity of these tests and to establish their clinical usefulness. PMID:24192253

    To evaluate long-term efficacy and safety of collagenase clostridium histolyticum (CCH) after the third year of a 5-year nontreatment follow-up study, Collagenase Option for Reduction of Dupuytren Long-Term Evaluation of Safety Study. This study enrolled Dupuytren contracture patients from 5 previous clinical studies. Beginning 2 years after their first CCH injection, we re-evaluated patients annually for joint contracture and safety. Recurrence in a previously successfully treated joint (success = 0° to 5° contracture after CCH administration) was defined as 20° or greater worsening in contracture in the presence of a palpable cord or medical/surgical intervention to correct new or worsening contracture. We assessed partially corrected joints (joints reduced 20° or more from baseline contracture but not to 0° to 5°) for nondurable response, also defined as 20° or greater worsening of contracture or medical/surgical intervention. Of 1,080 CCH-treated joints (648 metacarpophalangeal [MCP]; 432 proximal interphalangeal [PIP]; n = 643 patients), 623 (451 MCP, 172 PIP) had achieved 0° to 5° contracture in the original study. Of these joints, 35% (217 of 623) recurred (MCP 27%; PIP 56%). Of these recurrences, an intervention was performed in 7%. Of the 1,080 CCH-treated joints, 301 were partially corrected in the original study. Of these, 50% (150 of 301; MCP: 38% [57 of 152]; PIP: 62% [93 of 149]) had nondurable response. We identified no new long-term or serious adverse events attributed to CCH during follow-up. Anti-clostridial type I collagenase and/or anti-clostridial type II collagenase antibodies were reported for 96% or more of patients who received 2 or more CCH injections and 82% who received 1 injection. The recurrence rate, which is comparable to other standard treatments, and the absence of long-term adverse events 3 years after initial treatment indicate that CCH is an effective and safe treatment for Dupuytren contracture.

    Psychiatric Clinical Knowledge Enhancement System (PSYCKES) is an innovative information system that presents patient medication history in tabular and graphical form. The system is designed to support therapeutic decision making. In this paper, we present a multifaceted cognitive evaluation of this system. The evaluation includes a cognitive walkthrough which is a task-analytic method for usability evaluation. We also conducted cognitive studies of two trainee and two attending psychiatrists using the system. One of the attending subjects is presented as a case study. An objective of this research is to characterize the way PSYCKES mediates reasoning. The study found that clinicians were able to use the system effectively to extract and coordinate information and draw appropriate inferences. The expert clinicians were better able to construct a coherent patient representation. The study also documented a few usability problems pertaining to the temporal integration of patient data. PSYCKES is a multifaceted tool that can significantly enhance therapeutic decision making.

    To evaluate the clinical and radiological results and the impact on quality of life of the reverse shoulder arthroplasty. Retrospective case series evaluating 13 patients undergoing reverse shoulder arthroplasty with at least two years of clinical follow-up. Clinical evaluation was performed before and after surgery with the ASES and VAS scales and hand-mouth, hand-neck, and hand-head functional tests. Quality of life was measured with the SF-12 questionnaire. The rate of complications and radiographic postoperative findings were recorded. The patients improved from 23.1 ± 15 to 82.7 ± 15 according to ASES scale (p < 0.001). The physical component of the SF-12 increased from 31.7 ± 6.9 to 47.1 ± 8.6 (p < 0.001), while the emotional increased from 48 ± 12.3 to 55.5 ± 7.5 (p = 0.061). The pain reduced from 7.9 to 1 according to the VAS (p = 0.002). The performance on the hand-mouth, hand-neck, and hand-head functional tests showed significant improvement (p = 0.039, p < 0.001 and p < 0.001, respectively). Complications occurred in 15% of patients and notching, in 31%. Reverse shoulder arthroplasty led to a significant clinical improvement according to the ASES and VAS scales. The quality of life has improved according to the physical aspect of the SF-12, and showed a trend of improvement in the emotional aspect. The complication rate was 15%, and notching occurred in 31%.

    Mesiodens is a common clinical finding among children and has a higher prevalence in Asian populations. The timing of the removal of mesiodens remains controversial. Clinical studies comparing early versus late removal are lacking. The aim of this retrospective study was to evaluate the frequency of clinical complications regarding the timing of childhood mesiodens removal and to explore the factors associated with complications following mesiodens removal. In total, 384 Taiwanese children diagnosed with unerupted mesiodens who had attended the Pediatric Dentistry Department, Taipei Veteran General Hospital, Taipei, Taiwan from 2005 to 2012 were identified as potential participants. Among these patients, 105 children had received surgical odontectomy of the mesiodens under general anesthesia and had complete longitudinal clinical and radiographic follow-up records, including computed tomography (CT) evaluations; these patients were enrolled. The influence of age, the developmental stage of the adjacent permanent teeth, and the location of the mesiodens were explored regarding complications that were noted at the time of surgery, injury to the adjacent permanent teeth during surgical intervention, and the need for orthodontic treatment after surgery. The 105 children enrolled had 145 mesiodens. Removal of the mesiodens before the child was 5 years of age or 1/3 root-completed was associated with fewer complications at the time of surgery and a reduced need for orthodontic treatment after surgery. However, no significant difference was noted between the different groups in terms of surgical injury to the adjacent permanent teeth. The early removal of an unerupted mesiodens before the age of 5 years would seem to reduce complications and the need for orthodontic treatment. With the help of general anesthesia and evaluation by CT imaging, concerns regarding the child's cooperation and the possibility of damage to adjacent permanent teeth during early surgical

    For decades, resin composites have been used with increasing frequency as posterior restorative materials, because of the demand for aesthetic restoration. This study evaluated the six-year clinical performance of Filtek P60 (3M ESPE) packable composite restorations in combination with a one-bottle etch and rinse adhesive, Single Bond (3M ESPE), in Class II restorations. A total of 47 restorations were placed in the Class II cavity preparations (27 premolars and 20 molars) of 33 patients (22 female/11 male; mean age 34) by the same operator. The restorations were evaluated by two examiners at baseline and 1, 2, 3 and 6 years according to the method developed by Ryge, which also is known as the United States Public Health Service (USPHS) criteria. The following characteristics were observed: marginal adaptation, anatomical form, surface texture, marginal discoloration, surface staining, post-operative sensitivity and secondary caries. The Chi-square and Wilcoxon signed rank test with Bonferroni adjustment were used for statistical analysis (p = 0.05). All the restorations received Alpha scores at baseline assessment, except for one restoration, which showed post-operative sensitivity. At the three-year recall examination, two patients, with a total of three restorations, were not included. From baseline to three years, only two of the 44 restorations changed from Alpha to Bravo, for numerous reasons. At the six-year recall, 44 restorations were available for examination. The majority of restorations exhibited Alpha or Bravo scores for the evaluated criteria. No significant differences were found for any of the clinical criteria (p > 0.05). Only two restorations needed to be repaired due to caries that began independently from the restorations. Three or four restorations showed slight surface staining and marginal discoloration. The clinical performance of the posterior composite restorations that were evaluated was acceptable after six years of service.

    This paper summarizes data collected as part of a project designed to identify and assess the technical and organizational problems associated with the implementation and evaluation of a Computerized Clinical Information System (CCIS), Micromedex, in three U.S. Department of Veterans Affairs Medical Centers (VAMCs). The study began in 1987 as a national effort to implement decision support technologies in the Veterans Administration Decentralized Hospital Computer Program (DHCP). The specific objectives of this project were to (1) examine one particular decision support technology, (2) identify the technical and organizational barriers to the implementation of a CCIS in the VA host environment, (3) assess the possible benefits of this system to VA clinicians in terms of therapeutic decision making, and (4) develop new methods for identifying the clinical utility of a computer program designed to provide clinicians with a new information tool. The project was conducted intermittently over a three-year period at three VA medical centers chosen as implementation and evaluation test sites for Micromedex. Findings from the Kansas City Medical Center in Missouri are presented to illustrate some of the technical problems associated with the implementation of a commercial database program in the DHCP host environment, the organizational factors influencing clinical use of the system, and the methods used to evaluate its use. Data from 4581 provider encounters with the CCIS are summarized. Usage statistics are presented to illustrate the methodological possibilities for assessing the "benefits and burdens" of a computerized information system by using an automated collection of user demographics and program audit trails that allow evaluators to monitor user interactions with different segments of the database.

    2010-01-01

    Introduction We aimed to assess the incidence and hospitalization rate of hip and "minor" fragility fractures in the Italian population. Methods We carried out a 3-year survey at 10 major Italian emergency departments to evaluate the hospitalization rate of hip, forearm, humeral, ankle, and vertebral fragility fractures in people 45 years or older between 2004 and 2006, both men and women. These data were compared with those recorded in the national hospitalizations database (SDO) to assess the overall incidence of fragility fractures occurring at hip and other sites, including also those events not resulting in hospital admissions. Results We observed 29,017 fractures across 3 years, with hospitalization rates of 93.0% for hip fractures, 36.3% for humeral fractures, 31.3% for ankle fractures, 22.6% for forearm/wrist fractures, and 27.6% for clinical vertebral fractures. According to the analyses performed with the Italian hospitalization database in year 2006, we estimated an annual incidence of 87,000 hip, 48,000 humeral, 36,000 ankle, 85,000 wrist, and 155,000 vertebral fragility fractures in people aged 45 years or older (thus resulting in almost 410,000 new fractures per year). Clinical vertebral fractures were recorded in 47,000 events per year. Conclusions The burden of fragility fractures in the Italian population is very high and calls for effective preventive strategies. PMID:21190571

    Clinical trials are fundamental to the advancement of medicine but constantly face recruitment difficulties. Various clinical trial search engines have been designed to help health consumers identify trials for which they may be eligible. Unfortunately, knowledge of the usefulness and usability of their designs remains scarce. In this study, we used mixed methods, including time-motion analysis, think-aloud protocol, and survey, to evaluate five popular clinical trial search engines with 11 users. Differences in user preferences and time spent on each system were observed and correlated with user characteristics. In general, searching for applicable trials using these systems is a cognitively demanding task. Our results show that user perceptions of these systems are multifactorial. The survey indicated eTACTS being the generally preferred system, but this finding did not persist among all mixed methods. This study confirms the value of mixed-methods for a comprehensive system evaluation. Future system designers must be aware that different users groups expect different functionalities.

    Current guides recommend to evaluate the patients with low back pain complaints with initial clinical assessment and history, and to utilize radiological or other imaging technics, in case of possible diagnosis. The aim of this study was to compare the findings of radiological and clinical assessment, and validate the reliability of spondylolisthesis diagnosed with clinical assessment. This study is conducted on 100 patients with, and 30 patients without (control group) radiological diagnosis of spondylolisthesis, who had applied to Department of Physical Therapy and Rehabilitation, Haydarpasa Numune Hospital with low back pain complaints in one and a half year. Clinic assessment was consisted of 20 parameters including examinations of motor system such as, sign of slipping observed on palpation and inspection, extension of trunk and increase in lumbar lordosis. Antero-posterior, lateral, oblique and lateral flexion/extension radiographies were used for radiological assessment. Slipping degree and lumbar lordosis angle were measured. Women/men patients ratio was 91/9 in spondylolisthesis group and 22/8 in control group. Age of 69% of patients were 50 and over. In both groups, sciatalgia was observed in more than half of the patients, and no significant difference was detected in localization (p > 0.05). In clinical assessment, weak and drooping abdominal wall, paravertebral muscle hypertrophy, increase in lumbar lordosis, sign of slipping observed on palpation and inspection, hamstring muscle spasm, pain during lateral trunk flexion-extension tasks and during double leg raising task were found to be positively correlated with radiological assesment (p < 0.05). In our study, a systematic clinical assessment was proved to be useful in determination of possible spondylolisthesis cases. Radiological assessments are required in order to make the diagnosis clear and to determine the grade and prognosis of spondylolisthesis. Advanced imaging techniques like MRI and CT

    Interventions aimed at improving chronic care typically consist of multiple interconnected parts, all of which are essential to the effect of the intervention. Limited attention has been paid to the use of routine clinical and administrative data in the evolution of these complex interventions. The purpose of this study is to examine the feasibility of routinely collected data when evaluating complex interventions and to demonstrate how a theory-based, realist approach to evaluation may increase the feasibility of routine data. We present a case study of evaluating a complex intervention, namely, the chronic care model (CCM), in Finnish primary health care. Issues typically faced when evaluating the effects of a complex intervention on health outcomes and resource use are identified by using routine data in a natural setting, and we apply context-mechanism-outcome (CMO) approach from the realist evaluation paradigm to improve the feasibility of using routine data in evaluating complex interventions. From an experimentalist approach that dominates the medical literature, routine data collected from a single centre offered a poor starting point for evaluating complex interventions. However, the CMO approach offered tools for identifying indicators needed to evaluate complex interventions. Applying the CMO approach can aid in a typical evaluation setting encountered by primary care managers: one in which the intervention is complex, the primary data source is routinely collected clinical and administrative data from a single centre, and in which randomization of patients into two research arms is too resource consuming to arrange. © 2014 John Wiley & Sons, Ltd.

    2014-01-01

    Social, behavioral, and cultural factors are clearly linked to health and disease outcomes. The medical social history is a critical evaluation of these factors performed by healthcare providers with patients in both inpatient and outpatient care settings. Physicians learn the topics covered in the social history through education and practice, but the topics discussed and documented in real-world clinical narrative have not been described at scale. This study applies large-scale automated topic modeling techniques to discover common topics discussed in social histories, to compare those topics to the medical textbook representation of those histories, and to compare topics between clinical settings to illustrate differences of clinical context on narrative content. Language modeling techniques are used to consider the extent to which inpatient and outpatient social histories share in their language use. Our findings highlight the fact that clinical context and setting are distinguishing factors for social history documentation, as the language of the hospital wards is not the same as that of the ambulatory clinic. Moreover, providers receive little feedback on the quality of their documentation beyond that needed for billing processes. The findings in this study demonstrate a number of topics described in textbooks - schooling, religion, alternative health practices, stressors, for example - do not appear in social histories in either clinical setting.

    This article is a report of the development and psychometric testing of the Swedish version of the Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale. To achieve quality assurance, collaboration between the healthcare and nursing systems is a pre-requisite. Therefore, it is important to develop a tool that can measure the quality of clinical education. The Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale is a previously validated instrument, currently used in several universities across Europe. The instrument has been suggested for use as part of quality assessment and evaluation of nursing education. The scale was translated into Swedish from the English version. Data were collected between March 2008 and May 2009 among nursing students from three university colleges, with 324 students completing the questionnaire. Exploratory factor analysis was performed on the 34-item scale to determine construct validity and Cronbach's alpha was used to measure the internal consistency. The five sub-dimensions identified in the original scale were replicated in the exploratory factor analysis. The five factors had explanation percentages of 60.2%, which is deemed sufficient. Cronbach's alpha coefficient for the total scale was 0.95, and varied between 0.96 and 0.75 within the five sub-dimensions. The Swedish version of Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale has satisfactory psychometric properties and could be a useful quality instrument in nursing education. However, further investigation is required to develop and evaluate the questionnaire.

    With antimicrobial resistance increasing worldwide, there is a great need to use automated antimicrobial decision support systems (ADSSs) to lower antimicrobial resistance rates by promoting appropriate antimicrobial use. However, they are infrequently used mostly because of their poor interoperability with different health information technologies. Ontologies can augment portable ADSSs by providing an explicit knowledge representation for biomedical entities and their relationships, helping to standardize and integrate heterogeneous data resources. We developed a bacterial clinical infectious diseases ontology (BCIDO) using Protégé-OWL. BCIDO defines a controlled terminology for clinical infectious diseases along with domain knowledge commonly used in hospital settings for clinical infectious disease treatment decision-making. BCIDO has 599 classes and 2355 object properties. Terms were imported from or mapped to Systematized Nomenclature of Medicine, Unified Medical Language System, RxNorm and National Center for Bitechnology Information Organismal Classification where possible. Domain expert evaluation using the “laddering” technique, ontology visualization, and clinical notes and scenarios, confirmed the correctness and potential usefulness of BCIDO. PMID:24551353

BCIDO has 599 classes and 2355 object properties. Terms were imported from or mapped to Systematized Nomenclature of Medicine, Unified Medical Language System, RxNorm and National Center for Bitechnology Information Organismal Classification where possible. Domain expert evaluation using the "laddering" technique, ontology visualization, and clinical notes and scenarios, confirmed the correctness and potential usefulness of BCIDO.

    Services for Rheumatoid Arthritis (RA) have evolved with the development of independently led outreach Rheumatology Practitioner (RP) clinics in Primary Care (PC). Their clinical and cost effectiveness, compared with Secondary Care (SC) services, has not been assessed. The RECIPROCATE study aims to evaluate their clinical and cost effectiveness. This part of the study aimed to explore health professionals' opinions of rheumatology outreach service. Using a qualitative design, semi-structured interviews were conducted with GPs, practice nurses, hospital doctors and RPs, from one hospital and seven PC practices in Norfolk, to elicit their opinions of the service. The interviews were analysed using thematic analysis. All participants agreed the service was supportive and valuable providing high quality personalised care, disease management, social, and educational support. Advantages identified included convenience, continuity of care and proximity of services to home. RPs helped bridge the communication gap between PC and SC. Some participants suggested having a doctor alongside RPs. The service was considered to be cost effective for patients but there was uncertainty about cost effectiveness for service providers. Few disadvantages were identified the most recurring being the lack of other onsite services when needed. It was noted that more services could be provided by RPs such as prescribing and joint injections as well as playing a more active role in knowledge transfer to PC. Professionals involved in the care of RA patients recognised the valuable role of the RP outreach clinics. This service can be further developed in rheumatology and the example can be replicated for other chronic conditions.

  4. Criteria for clinical translucency evaluation of direct esthetic restorative materials

    PubMed Central

    2016-01-01

    The purpose of this review was to suggest practical criteria for the clinical translucency evaluation of direct esthetic restorative materials, and to review the translucency with these criteria. For the evaluation of reported translucency values, measuring instrument and method, specimen thickness, background color, and illumination should be scrutinized. Translucency parameter (TP) of 15 to 19 could be regarded as the translucency of 1 mm thick human enamel. Visual perceptibility threshold for translucency difference in contrast ratio (ΔCR) of 0.07 could be transformed into ΔTP value of 2. Translucency differences between direct and indirect resin composites were perceivable (ΔTP > 2). Universal and corresponding flowable resin composites did not show perceivable translucency differences in most products. Translucency differed significantly by the product within each shade group, and by the shade group within each product. Translucency of human enamel and perceptibility threshold for translucency difference may be used as criteria for the clinical evaluation of translucency of esthetic restorative materials.

    Background: Peripheral nerve injuries with substance loss are challenges to surgeons because direct suture repair may result in malfunction due to nerve suture tension. Autologous nerve grafts are alternatives for treating those lesions; however, harvesting grafts adds morbidity at donor sites. Synthetic substitutes are options to bridge the gaps in these situations. The caprolactone neurotubes are used to assist nerve regeneration, but the literature lacks studies that evaluate their results. Methods: This research was designed to clinically evaluate patients undergoing repair of peripheral nerves with that conduit. We described results of 12 case series consisting of operations with Neurolac®. All nerves severed were sensory and had small gaps (ie, less than 25 mm). Subjective and objective clinical evaluations were performed and registered. Results: Physical examination by monofilament testing and 2-point discrimination showed results rated as good or excellent. However, the patients had complaints regarding sensory changes. Conclusions: Synthetic bioabsorbable guides for nerve repair are promising. The caprolactone conduits were demonstrated to be a safe option treatment and with a simple technique. Although in our study there were some operative complications, they were in line with previous descriptions in the literature. This case series added information about the treatment prognosis, but a higher evidence level study is necessary for decision making.

    2014-01-01

    We evaluated the potential use of RxNorm to provide standardized representations of generic drug name and route of administration to facilitate management of drug lists for clinical decision support (CDS) rules. We found a clear representation of generic drug name but not route of administration. We identified several issues related to data quality, including erroneous or missing defined relationships, and the use of different concept hierarchies to represent the same drug. More importantly, we found extensive semantic precoordination of orthogonal concepts related to route and dose form, which would complicate the use of RxNorm for drug-based CDS. This study demonstrated that while RxNorm is a valuable resource for the standardization of medications used in clinical practice, additional work is required to enhance the terminology so that it can support expanded use cases, such as managing drug lists for CDS.

Results The results demonstrated that novices and experts share a common neural network in addition to nonoverlapping neural resources. However, experts manifested greater neural processing efficiency in regions such as the prefrontal cortex during nonanalytical reasoning. Conclusions These findings reveal a multinetwork system that supports the dual-process mode of expert clinical reasoning during medical evaluation. PMID:25798328

    The observation and 3D quantification of arbitrary scenes using optical imaging systems is challenging, but increasingly necessary in many fields. This paper provides a technical basis for the application of plenoptic cameras in medical and medical robotics applications, and rigorously evaluates camera integration and performance in the clinical setting. It discusses plenoptic camera calibration and setup, assesses plenoptic imaging in a clinically relevant context, and in the context of other quantitative imaging technologies. We report the methods used for camera calibration, precision and accuracy results in an ideal and simulated surgical setting. Afterwards, we report performance during a surgical task. Test results showed the average precision of the plenoptic camera to be 0.90mm, increasing to 1.37mm for tissue across the calibrated FOV. The ideal accuracy was 1.14mm. The camera showed submillimeter error during a simulated surgical task.

    Severe alveolar bony resorption in the edentulous posterior maxilla and pneumatization of the maxillary sinus wall make traditional implant placement impossible in the posterior maxilla. To reconstruct the severely resorbed maxilla for dental implant placement, 1 successful technique is to elevate the maxillary sinus floor using demineralized bone matrix (DBM) grafts. The purpose of this study was to evaluate a histologic and histomorphometric evaluation of DBM grafts in the human maxilla. Nine months after grafting, at the time of dental implantation, biopsy samples were taken from the grafted areas of 8 patients and were analyzed histologically. All the sinus lifts were successful in the clinical study conducted after implantation. Resorption of the graft materials and new bone formation were observed, and there was direct deposition of bone on the surface of the graft particles. The results of this study indicate that limited maxillary sinus lift with DBM graft material is a clinically reliable preimplant procedure.

    This study evaluated the clinical performance of 39 light and heat polymerized fixed partial bridges made with a substructure of preimpregnated, unidirectional fiber-reinforced composite, or FRC, veneered with a hybrid particu late composite. The authors evaluated 22 extracoronal, full-coverage retainer prostheses and 17 intracoronal, partial-coverage retainer prostheses placed over a 37-month period. All substructures initially were fabricated with a low-volume FRC. The authors reevaluated this design after early failures occurred, leading to a substructure with a higher volume of FRC. All prostheses were assessed for surface integrity, anatomical contour, marginal integrity and structural integrity at several intervals. The data show that survival was associated primarily with substructure design volume. When patients with severe parafunctional habits were excluded, the survival rate was 95 percent for prostheses made with a high-volume substructure (survival range, 2.77 to 4.30 years; mean +/- standard deviation survival, 3.75 +/- 0.4 years). Retainer configuration did not have a statistically significant influence on clinical survival. For all surviving prostheses, the authors observed few changes in any clinical parameters from baseline to 48 months. A loss of surface luster was observed in the majority of cases. Repairable surface defects were detected on two prostheses at 24 months. Scanning electron microscopic analyses indicated no exposed fibers on the occlusal surface and minimal wear. This study shows that a unidirectional, preimpregnated FRC can be used successfully to make bridges of variable retainer designs that last up to four or more years when a high-volume substructure is used. Short-span polymer prostheses made with particulate composite and unidirectional glass FRC can be used in certain clinical situations in which a metal substructure is not desired.

    To validate baseline caries risk classifications according to the Cariogram model with the actual caries development over a 3-year period in a group of young adults living in Sweden. The study group consisted of 1,295 19-year-old patients that completed a comprehensive clinical baseline examination, including radiographs and salivary tests. An individual caries risk profile was computed and the patient was placed in one of five risk categories. After 3 years, 982 patients (75.8%) were re-examined and caries increment for each patient was calculated. The outcome was expressed as sensitivity, specificity and predictive values and compared with a risk assessment scheme used in Public Dental Service. The drop-outs displayed more risk factors and a significantly higher caries burden at baseline compared with those that remained in the project (p < 0.05). There was a strong association between the Cariogram risk categories and the 3-year caries increment on cavity level but the predictive values were modest. The high or very high caries risk categories yielded high specificities (>90%) but poor sensitivities. The low risk groups displayed higher sensitivities on expense of impaired specificities. No combinations proved clinically useful values according to Yuoden's index. Within the limitations of the present study, the computer-based Cariogram did not perform better than a caries risk assessment scheme based on past caries experience and caries progression, over a 3-year period in young adults.

    This three arm study was designed to make CRC screening with FOBTs more accessible, understandable and actionable for patients cared for in predominantly rural Federally Qualified Health Centers. Patients in an enhanced version of usual care received an annual CRC recommendation and FOBT kit; those in the education arm additionally received brief literacy and culturally appropriate education and those in the nurse arm received the education by a nurse manager who followed up by telephone. Baseline FOBT rates in this population were 3 %. We evaluated if FOBT rates could be sustained over 3 years. A three-arm, quasi-experimental evaluation was conducted among eight clinics in Louisiana. Screening efforts included: (1) enhanced usual care, (2) literacy-informed education of patients, and (3) education plus nurse support. Overall, 961 average-risk patients, ages 50-85, eligible for routine CRC screenings were recruited. The primary outcome was completing three annual FOBT tests. Of 961 patients enrolled, 381 (39.6 %) participants did not complete a single FOBT, 60.4 % completed at least one FOBT of which 318 (33.1 %) completed only one, 162 (16.9 %) completed two and 100 (10.4 %) completed three FOBTs over the 3-year period (the primary study outcome). The primary outcome, return of three FOBT kits over the 3-year period, was achieved by 4.7 % in enhanced care, 11.4 % in education and 13.6 % in the nurse arm (p = 0.005). Overall 3-year FOBT screening rates were not sustained with any of the three interventions, despite reports of promising interim results at years 1 and 2. New strategies for sustaining FOBT screening over several years must be developed.

  16. Electronic Clinical Safety Reporting System: A Benefits Evaluation

    PubMed Central

    Background Eastern Health, a large health care organization in Newfoundland and Labrador (NL), started a staged implementation of an electronic occurrence reporting system (used interchangeably with “clinical safety reporting system”) in 2008, completing Phase One in 2009. The electronic clinical safety reporting system (CSRS) was designed to replace a paper-based system. The CSRS involves reporting on occurrences such as falls, safety/security issues, medication errors, treatment and procedural mishaps, medical equipment malfunctions, and close calls. The electronic system was purchased from a vendor in the United Kingdom that had implemented the system in the United Kingdom and other places, such as British Columbia. The main objective of the new system was to improve the reporting process with the goal of improving clinical safety. The project was funded jointly by Eastern Health and Canada Health Infoway. Objective The objectives of the evaluation were to: (1) assess the CSRS on achieving its stated objectives (particularly, the benefits realized and lessons learned), and (2) identify contributions, if any, that can be made to the emerging field of electronic clinical safety reporting. Methods The evaluation involved mixed methods, including extensive stakeholder participation, pre/post comparative study design, and triangulation of data where possible. The data were collected from several sources, such as project documentation, occurrence reporting records, stakeholder workshops, surveys, focus groups, and key informant interviews. Results The findings provided evidence that frontline staff and managers support the CSRS, identifying both benefits and areas for improvement. Many benefits were realized, such as increases in the number of occurrences reported, in occurrences reported within 48 hours, in occurrences reported by staff other than registered nurses, in close calls reported, and improved timelines for notification. There was also user satisfaction

    The goal of this investigation was to evaluate the efficacy of dental implants with a surface that was sandblasted with large grit and acid etched in a human model. Seven patients volunteered to allow the biopsy of a small implant in exchange for complete dental rehabilitation at no cost. All biopsy sites received soft and hard tissue reconstruction, and this report provides observation of successful bone-to-implant contact and successful prosthesis construction for the patient. The patients enthusiastically reported improved quality of life as a result of participation in this study. The surgeons’ confidence in this implant was reflected by the clinical and histologic result of the study.

    2015-01-01

    Balance disorders are common issues for aging populations due to the effects of normal aging on peripheral vestibular structures. These changes affect the results of vestibular function evaluations and make the interpretation of these results more difficult. The objective of this article is to review the current state of knowledge of clinically relevant vestibular measures. We will first focus on otolith function assessment methods cervical-VEMP (cVEMP) and ocular-VEMP (oVEMP), then the caloric and video-head impulse test (vHIT) methods for semicircular canals assessment. cVEMP and oVEMP are useful methods, though research on the effects of age for some parameters are still inconclusive. vHIT results are largely independent of age as compared to caloric stimulation and should therefore be preferred for the evaluation of the semicircular canals function.

    Purpose. To evaluate the clinical applicability of a telemonitoring system: telemetric system for collection and distant surveillance of medical information (TEMEO). Methods. We evaluated 60 patients, applying simultaneously standard Holter ECG and telemonitoring. Two different comparisons were performed: (1) TEMEO ECG with standard 12-lead ECG; (2) TEMEO Holter with standard ECG Holter. Results. We found a very high coincidence rate (99.3%) between TEMEO derived ECGs and standard ECGs. Intraclass correlation coefficient analysis revealed high and significant correlation coefficients regarding average, maximal, and minimal heart rate, % of time in tachycardia, single supraventricular ectopic beats (SVEB), and single and couplets of ventricular ectopic beats (VEB) between Holter ECG and TEMEO derived parameters. Couplets of SVEB were recorded as different by the two monitoring systems, however, with a borderline statistical significance. Conclusions. TEMEO derived ECGs have a very high coincidence rate with standard ECGs. TEMEO patient monitoring provides results that are similar to those derived from a standard Holter ECG. PMID:23097720

    The number of university students requesting services based on the Americans with Disabilities Act for learning disabilities and ADHD-related difficulties has increased, although there are limited reports in the literature describing these evaluations. The current study describes a sample of 140 individuals (59% women) who presented for psycho-educational evaluation at the university psychology clinic. The students were individually administered self-report, cognitive, academic, and attention measures as indicated, and diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Difficulties with mathematics, attention, and reading concerns were the most frequent presenting complaints. 46 students met criteria for one or more learning disorders and 20 students met criteria for a diagnosis of ADHD. Test scores are summarized and findings compared with the literature.

    Although the structure of executive function (EF) during adulthood is characterized by both unity and diversity, recent evidence suggests that preschool EF may be best described by a single factor. The latent structure of EF was examined in 228 3-year-olds using confirmatory factor analysis. Children completed a battery of executive tasks that differed in format and response requirements and in putative working memory and inhibitory control demands. Tasks appeared to be age appropriate, with adequate sensitivity across the range of performance and without floor or ceiling effects. Tests of the relative fit of several alternative models supported a single latent EF construct. Measurement invariance testing revealed less proficient EF in children at higher sociodemographic risk relative to those at lower risk and no differences between boys and girls. At 3years of age, when EF skills are emerging, EF appears to be a unitary, more domain-general process.

    The reported study explored the implications of informal computer-mediated social support for the well-being of individuals coping with illness over the course of 3 years. A panel study was conducted in which respondents--bloggers writing about their experiences living with a health condition--reported on their perceptions of social support and well-being during 2010 and again during 2013. Among respondents who completed both questionnaires (n = 49), increases in support availability from family and friends were related to improvements in bloggers' health self-efficacy as well as improvements in bloggers' loneliness, particularly among those who also experienced increased support availability from blog readers. Increased blog reader support availability was associated with improvements in bloggers' health-related uncertainty. Among respondents who completed the initial questionnaire (N = 121), a survival analysis showed that neither support available from family and friends nor support from blog readers predicted continued health blogging over the 3-year period.

    The construction and evaluation of a simple drawing test for assessment of arm-hand function in children of 1--3 years of age are described. A thick crayon (1.2 x 10 cm) and a piece of white paper (20 x 30 cm) are the only equipment needed. The need, when assessing fine motor development, of a test for evaluation of arm-hand function and the advantages of the test described are discussed. It is concluded that the method is of diagnostic value in children with CNS and neuromuscular disorders and is a useful tool for clinical studies and for routine developmental examination.

    American College of Chest Physicians (CHEST) clinical practice guidelines on the evaluation of pulmonary nodules may have low adoption among clinicians in Asian countries. Unique patient characteristics of Asian patients affect the diagnostic evaluation of pulmonary nodules. The objective of these clinical practice guidelines was to adapt those of CHEST to provide consensus-based recommendations relevant to practitioners in Asia. A modified ADAPTE process was used by a multidisciplinary group of pulmonologists and thoracic surgeons in Asia. An initial panel meeting analyzed all CHEST recommendations to achieve consensus on recommendations and identify areas that required further investigation before consensus could be achieved. Revised recommendations were circulated to panel members for iterative review and redrafting to develop the final guidelines. Evaluation of pulmonary nodules in Asia broadly follows those of the CHEST guidelines with important caveats. Practitioners should be aware of the risk of lung cancer caused by high levels of indoor and outdoor air pollution, as well as the high incidence of adenocarcinoma in female nonsmokers. Furthermore, the high prevalence of granulomatous disease and other infectious causes of pulmonary nodules need to be considered. Therefore, diagnostic risk calculators developed in non-Asian patients may not be applicable. Overall, longer surveillance of nodules than those recommended by CHEST should be considered. TB in Asia favors lesser reliance on PET scanning and greater use of nonsurgical biopsy over surgical diagnosis or surveillance. Practitioners in Asia are encouraged to use these adapted consensus guidelines to facilitate consistent evaluation of pulmonary nodules. Copyright © 2016 American College of Chest Physicians.

    Performance validity tests (PVTs) are not widely used beyond medico-legal contexts in the UK. A UK survey suggests clinicians have reservations about their accuracy in clinical settings. This study sought to explore the validity of PVTs in an acute adult neuropsychology setting and to establish a potential "false positive" (FP) base rate. Failures on the Medical Symptom Validity Test (MSVT) in a consecutive clinical series of 405 patients were evaluated systematically and allocated to groups depending on clinical context. All failures were checked against the test's "dementia profile". Of the 405 participants, 329 passed the MSVT (81.2%), while 76 participants (18.8%) failed based on standard criteria. A 5.2% rate of potentially 'unexplained' failures was found. Other reasons for failure were classified as: presumed malingered neurocognitive dysfunction (4.6%), dementia/significant cognitive impairment (3.7%), technical/visual problems (1.8%), and "unexplained failure" with contributory factors (2.4%). These results suggest test specificity between 0.95 and 0.90. Most of the clinically significantly impaired patients matched the dementia profile (86.7%). Our results support the sensitivity, but not the specificity, of the dementia profile. However, approximately 1 in 20 patients failed the MSVT despite an otherwise unremarkable neuropsychological presentation; moreover, mood and pain may affect MSVT performance. Clinical implications for interpreting test scores are discussed.

Many researchers identified essential mainstream performance indicators needed to improve the CED's performance. These studies revealed mainstream performance indicators that use the database of a CED to evaluate its performance. In this work, we believe that those indicators are insufficient for hospitals. Additional important indicators should be included to improve the evaluation accuracy. Therefore, we added new indicators: technical/maintenance indicators, economic indicators, intrinsic criticality indicators, basic hospital indicators, equipment acquisition, and safety indicators. Data is collected from 10 hospitals that cover different types of healthcare organizations. We developed a software tool that analyses collected data to provide a score for each CED under evaluation. Our results indicate that there is an average gap of 67% between the CEDs' performance and the ideal target. The reasons for the noncompliance are discussed in order to improve performance of CEDs under evaluation.

    Students are a popular source of data to evaluate the performance of clinical teachers. Instruments to obtain student evaluations must have proven validity. One aspect of validity that often remains underexposed is the possibility of effects of between-student differences and teacher and student characteristics not directly related to teaching performance. The authors examined the occurrence of such effects, using multilevel analysis to analyse data from the Maastricht clinical teaching questionnaire (MCTQ), a validated evaluation instrument, in a veterinary curriculum. The 15-item MCTQ covers five domains. The authors used multilevel analysis to divide the variance in the domain scores in components related to, respectively, teachers and students. They estimated subsequent models to explore how the MCTQ scores are dependent on teacher and student characteristics. Significant amounts of variance in student ratings were due to between-teacher differences, particularly for learning climate, modelling and coaching. The effects of teacher and student characteristics were mostly non-significant or small. Large portions of variance in MCTQ scores were due to differences between teachers, while the contribution of student and teacher characteristics was negligible. The results support the validity of student ratings obtained with the MCTQ for evaluating teacher performance.

    Purpose: Focal radiosurgery is a common treatment modality for trigeminal neuralgia (TN), a neuropathic facial pain condition. Assessment of treatment effectiveness is primarily clinical, given the paucity of investigational tools to assess trigeminal nerve changes. The efficiency of radiosurgery is related to its highly precise targeting. We assessed clinically the targeting accuracy of radiosurgery with Gamma knife. We hypothesized that trigeminal tractography provides more information than 2D-MR imaging, allowing detection of unique, focal changes in the target area after radiosurgery. Methods: Sixteen TN patients (2 females, 4 male, average age 65.3 years) treated with Gamma Knife radiosurgery, 40 Gy/50% isodose line underwent 1.5Tesla MR trigeminal nerve . Target accuracy was assessed from deviation of the coordinates of the target compared with the center of enhancement on post MRI. Radiation dose delivered at the borders of contrast enhancement was evaluated Results: The median deviation of the coordinates between the intended target and the center of contrast enhancement was within 1mm. The radiation doses fitting within the borders of the contrast enhancement the target ranged from 37.5 to 40 Gy. Trigeminal tractography accurately detected the radiosurgical target. Radiosurgery resulted in 47% drop in FA values at the target with no significant change in FA outside the target, suggesting that radiosurgery primarily affects myelin. Tractography was more sensitive, since FA changes were detected regardless of trigeminal nerve enhancement Conclusion: The median deviation found in clinical assessment of gamma knife treatment for TN Is low and compatible with its high rate of efficiency. DTI parameters accurately detect the effects of focal radiosurgery on the trigeminal nerve, serving as an in vivo imaging tool to study TN. This study is a proof of principle for further assessment of DTI parameters to understand the pathophysiology of TN and treatment effects.

    The development and expanded use of endosseous dental implants over the last two decades have been remarkably rapid. It is, therefore, imperative that the dental profession closely monitor the performance of root-form implants used in a variety of applications. The Dental Implant Clinical Research Group (DICRG) was established in 1990 by the Department of Veterans Affairs as a forum for conducting prospective, multidisciplinary, multicentered studies in the field of implant dentistry. The DICRG comprised 30 VA medical centers and 2 dental schools at the time of this study. This paper reports on the survival of hydroxyapatite (HA)-coated grooved implants used to replace single missing teeth in anterior maxillae at 3 years post-implant placement. During a 4-year accrual period, a total of 247 single-tooth implant restorations were placed in anterior maxillae. This paper focuses on the survival of 222 implants (149 patients) for which 3-year data were recorded for the period from placement. Survival was examined with respect to patient demographics and health status, implant location, surgical variables, and 2-week post-placement use of chlorhexidine digluconate (0.12%) rinses. Implant stability was recorded using a hand-held probe. Periodontal-type measures were recorded and evaluated, and all complications related to osseointegration were noted. Failure was defined as removal of the implant for any reason. Establishment and maintenance of osseointegration at 3 years post-placement was 97.3%. During this 3 year period, 6 implants were removed due to either failure to osseointegrate or loss of osseointegration. Implant length correlated positively with 3-year survival (P = 0.003, exact test). The use of preoperative antibiotics was nearly significant to implant survival (P = 0.051. Pearson chi-square). Mean stability values (PTVs) increased incrementally from -4.5 at uncovering to +1.1 at 36 months, indicating a decrease in stability of the bone

    Butantan Institute is a public Brazilian biomedical research-manufacturer center affiliated to the São Paulo State Secretary of Health. Currently, Butantan is one of the main public producers of vaccines, antivenoms, and antitoxins in Latin America. The partnership between Butantan and the National Institutes of Health (NIH) of the United Sates has been one of the longest and most successful partnerships in the development and manufacturing of new vaccines. Recently, Butantan Institute has developed and manufactured a lyophilized tetravalent live attenuated dengue vaccine with the four dengue viruses attenuated and licensed from the Laboratory of Infectious Diseases at The National Institutes of Allergy and Infectious Diseases (LID/NIAID/NIH). The objective of this paper is to describe the clinical evaluation strategies of a live attenuated tetravalent dengue vaccine (Butantan-DV) developed and manufactured by Butantan Institute. These clinical strategies will be used to evaluate the Butantan-DV Phase III trial to support the Butantan-DV licensure for protection against any symptomatic dengue caused by any serotype in people aged 2 to 59 years.

    This study was designed to describe the characteristics and clinical outcome of patients diagnosed with plantar vein thrombosis. Patients presenting with sudden pain and/or swelling of the foot were evaluated by duplex scanning of the affected leg. All the main foot veins were imaged with high resolution multi-linear array transducers. The location and extent of thrombosis was recorded in detail. All patients were scheduled for clinical and ultrasound follow-up within a week from the diagnosis and at various intervals thereafter. Acute thrombosis was found in the plantar veins in 11 patients of whom 7 were females. Pain was presented in all patients, swelling in 8 and the left foot was involved in 7. From the risk factors evaluated, the most common were recent surgery 4, use of contraceptive pills 3, followed by malignancy, airplane travel, HIV-AIDS infection, and past history of DVT in one each. Plantar veins were exclusively affected in 8, with lower segment of the posterior tibial veins in 2 and the great saphenous vein in 1. In the follow up, there was evidence of thrombosis extension in 3 patients. At six months partial recanalization was found in 9 and complete in 2. Pain and swelling of the foot can be caused by plantar vein thrombosis. Complete or partial recanalization occurs in these patients by 6 months. Thrombi in the plantar veins can progress more proximally with the possibility of postthrombotic events.

    For mobile technology to be accepted at point of care in healthcare environments there is a need to demonstrate benefits whilst ameliorating the risks and challenges. To provide a standardised approach to evaluation of mobile technology a simulation protocol was developed to provide guidance for its use in healthcare environments. Simulated conditions provide the opportunity to assess intended and unintended consequences and identify potential workarounds when using technology. The protocol can also be used to demonstrate the importance of the development of digital professionalism by end-users prior to students entering the clinical practice setting. The mobile technology protocol was adapted from a health information systems protocol developed and used at the ITX Lab, Denmark for use in other simulation laboratories. Use case scenarios were developed to enable evaluation of mobile technology for mobile learning of nurses, nurse supervisors, students and patients. The scenarios can be used in a range of simulated environments including hospital bedside, outpatient clinic or community settings. A case study exemplar of a nurse and patient is included to demonstrate how the mobile technology protocol can be applied.

    Summary Increasingly attention is shifting towards delivering essential packages of care, often based on clinical practice guidelines, as a means to improve maternal, child and newborn survival in low-income settings. Cost effectiveness analysis (CEA), allied to the evaluation of less complex intervention, has become an increasingly important tool for priority setting. Arguably such analyses should be extended to inform decisions around the deployment of more complex interventions. In the discussion, we illustrate some of the challenges facing the extension of CEA to this area. We suggest that there are both practical and methodological challenges to overcome when conducting economic evaluation for packages of care interventions that incorporate clinical guidelines. Some might be overcome by developing specific guidance on approaches, for example clarity in identifying relevant costs. Some require consensus on methods. The greatest challenge, however, lies in how to incorporate, as measures of effectiveness, process measures of service quality. Questions on which measures to use, how multiple measures might be combined, how improvements in one area might be compared with those in another and what value is associated with improvement in health worker practices are yet to be answered.

    The radiology department of Jackson Memorial Hospital processes 255,000 clinical examinations each year -- 65,000 of which are portable x rays. Film transportation and loss are major obstacles to the smooth operation of this department. To assist in the solution of these problems we have designed and begun the piecemeal installation of a clinical PACS. This system is based on a platform of IBM RISC/6000 computers and software developed by Genesys Corporation. The initial installation involved the digitization of the portable x rays from three ICUs. The images (in the form of a matrix of 2048 X 1648 pixels) are then entered into the network and can be viewed simultaneously in the radiology department and in the ICU. The second phase of installation, involving the images from two CT scanners and two MRI scanners is currently underway. We have evaluated the system from several standpoints. The first is user acceptance. The users are the radiologists who must make the diagnosis at the workstation and the referring physicians who need the diagnosis quickly but also require the image. The radiologists must be comfortable with their diagnosis based on the images presented at the two viewer workstation. This is compared to the use of a multiviewer which presents many radiographs simultaneously. The second parameter for evaluation involves the impact on patient care in terms of the time elapsed between the taking of the radiograph and the presentation to the physician of the image and the diagnosis.

    Paper-based surveys are an effective means of evaluating the quality of a clinical service. As part of ongoing quality improvement initiatives within our Genetics Program, new patients were invited to participate in a paper-based survey. Issues related to the quality of counseling based on educational/informational aspects (e.g. whether testing was explained fully, testing options, the meaning of normal/abnormal testing), competency, respect and nondirectiveness of counseling in addition to clinical environment/setting were evaluated. Data related to demographics, discipline seen within the program and whether the patient was seen by a physician or genetic counselor were also captured. Five hundred questionnaires were distributed. One hundred and forty-seven questionnaires were returned, with a response rate of 29.4 %. The majority of patients seen were prenatal (pregnant) patients and comprised a heterogeneous group including those seen for advanced maternal age and abnormal maternal serum screening. Overall, 98.6 % of respondents felt their appointment in genetics was a positive experience. Issues related to confidentiality, pros and cons of testing, meaning of an abnormal test result and time allotted for decision making were significantly different in some disciplines between genetic counselor and geneticist. However, when controlling for referral indication, these differences lost significance with the exception of issues relating to confidentiality and perceived time allotted to organize thoughts and questions. This survey provided valuable information to allow for improvement in the quality of the provision of service.

    An undetermined number of patients with temporomandibular joint (TMJ) symptoms have been treated with intra-articular disc implants composed of Teflon ethylene/propylene or Teflon polytetrafluoroethylene and aluminum oxide (Proplast-Teflon; Vitek, Houston, TX). These implants have shown the potential to fragment in situ resulting in nonbiodegradable particles that stimulate a giant cell reaction and lead to degeneration of local structures, pain, and limitation of mandibular opening. We examined the possible relationship between TMJ implants and persistent pain, responses to sensory stimuli, quality of life, and systemic immune dysfunction. This case series (32 patients) were referred from university-based orofacial pain centers and private practices from across the United States. Laboratory and clinical assessments evaluated orofacial pain symptoms, neurologic function, clinical signs and symptoms of rheumatologic disease, physical function, systemic measures of immune function, and behavioral measures. We found that TMJ implant patients appeared to have altered sensitivity to sensory stimuli, a higher number of tender points with a diagnosis of fibromyalgia, increased self-report of chemical sensitivity, higher psychologic distress and significantly lower functional ability. Systemic illness or autoimmune disease was not evident in this series of TMJ implant patients. Significant problems were noted on clinical assessment of TMJ implant patients. This is a US government work. There are no restrictions on its use.

    Bladder Exstrophy and Epispadias Complex (BEEC) is associated with an increased risk of impaired mental health, quality of life, and psychosocial functioning. Therefore, screening patients to help identify and evaluate potential psychosocial difficulty is arguably an important consideration for BEEC Services. To screen paediatric BEEC patients for a range of general psychosocial difficulties in a multi-disciplinary out-patient clinic setting. This cross-sectional evaluation was conducted between April 2012 and July 2013. Families attending BEEC multi-disciplinary out-patient clinics were asked to complete a range of standardised psychosocial questionnaires, including the Paediatric Quality of Life Inventory (PedsQL 4.0 Generic Core and Family Impact Module), the Strengths and Difficulties Questionnaire (SDQ), the Paediatric Index of Emotional Distress (PI-ED), and the Hospital Anxiety and Depression Scale (HADS). 108 children attended clinic of which 80 (74.1%) patients and their parents/carers completed some or all of the questionnaires. The mean patient age was 8.41 years (SD = 4.46, range = 1-18 years). There were more boys (N = 50, 62.5%) and the majority had a diagnosis of classic bladder exstrophy (N = 51, 63.8%), followed by primary epispadias (N = 22, 27.5%) and cloacal exstrophy (N = 7, 8.7%). Mean total scores fell within the average/normal range on all questionnaires used (See table below). However, variation around these means was high. Age, gender and diagnosis were found to significantly influence certain questionnaire responses with older-age groups, males, and those with classic bladder exstrophy particularly at risk across some domains. The children/adolescents self-reported better health related quality of life (HRQoL) scores than published results for a range of paediatric chronic health conditions. Differences between parent and child responses on both the PedsQL and SDQ favoured a more positive response on the child self-report questionnaire

    To evaluate the effects of a 3-year home exercise program on pulmonary function and exercise tolerance in mildly to moderately impaired patients with cystic fibrosis (CF) and to assess whether regular aerobic exercise is a realistic treatment option. Seventy-two patients with CF (7-19 years) were randomly assigned to an exercise group (a minimum of 20 minutes of aerobic exercise, at a heart rate of approximately 150 beats/min, 3 times weekly) or a control group (usual physical activity participation). Pulmonary function, exercise tolerance, clinical status, hospitalizations, and compliance with therapy were monitored during scheduled visits to the hospital's CF clinic. Sixty-five patients were included in the analyses. The control group demonstrated a greater annual decline in percent of predicted forced vital capacity compared with the exercise group (mean slope +/- SD, -2.42 +/- 4.15 vs -0.25 +/- 2.81; P =.02), with a similar trend for forced expiratory volume in 1 second (-3.47 +/- 4.93 vs -1.46 +/- 3. 55; P =.07). Patients remained compliant with the exercise program over the study period. An improved sense of well-being was reported with exercise. Pulmonary function declined more slowly in the exercise group than in the control group, suggesting a benefit for patients with CF participating in regular aerobic exercise. Consistent compliance with the home exercise program and a self-reported positive attitude toward exercise provide further evidence of the feasibility and value of including an aerobic exercise program in the conventional treatment regimen of patients with CF.

    Clinical pathways (CP) are comprehensive systematized patient care plans for specific procedures. The CP for morbid obesity was implemented in our department in September 2005. The aim of this study is to evaluate the clinical pathway for this procedure 1 year after implementation. A study was conducted on all the patients included in the CP since its implementation. The assessment criteria include degree of compliance, indicators of clinical care effectiveness, financial impact, and survey-based indicators of satisfaction. The results are compared to a series of patients undergoing surgery the year before the implementation of the CP. We analyzed the mean cost per procedure before and after CP implementation. Evaluation was made of a series of 49 consecutive patients who underwent surgery over the period of 1 year before the development of the CP and met the accepted inclusion criteria. The mean length of hospital stay was 7.95 days, and the mean cost per procedure before pathway implementation was 5,270.37 (+/-2,251.19) euros. One year after the implementation of the pathway, 70 patients were included. The mean length of hospital stay of the patients included in the CP was 5.1 days. The degree of compliance with stays was 71.4%. The most frequent reason for noncompliance was patient-dependent causes. The mean cost in the series of patients included in the CP was 4,532 (+/-1,753) euros. The CP for morbid obesity reduced both variability in professional care patterns and hospital costs; justifying the work involved in its development and implementation.

    The purpose of this study is to evaluate the clinical usefulness of modulated arc (mARC) treatment techniques. The mARC treatment plans for non-small-cell lung cancer (NSCLC) patients were made in order to verify the clinical usefulness of mARC. A pre-study was conducted to find the best plan condition for mARC treatment, and the usefulness of the mARC treatment plan was evaluated by comparing it with other Arc treatment plans such as tomotherapy and RapidArc plans. In the case of mARC, the optimal condition for the mARC plan was determined by comparing the dosimetric performance of the mARC plans developed by using various parameters, which included the photon energy (6 MV, 10 MV), the optimization point angle (6°- 10°intervals), and the total number of segments (36 - 59 segments). The best dosimetric performance of mARC was observed at a 10 MV photon energy, a point angle 6 degrees, and 59 segments. The treatment plans for the three different techniques were compared by using the following parameters: the conformity index (CI), homogeneity index (HI), the target coverage, the dose to the OARs, the number of monitor units (MU), the beam on time, and the normal tissue complication probability (NTCP). As a result, the three different treatment techniques showed similar target coverages. The mARC plan had the lowest V20 (volume of lung receiving > 20 Gy) and MU per fraction compared with both the RapidArc and the tomotherapy plans. The mARC plan reduced the beam on time as well. Therefore, the results of this study provide satisfactory evidence that the mARC technique can be considered as a useful clinical technique for radiation treatment.

    2012-01-01

    Background Services for Rheumatoid Arthritis (RA) have evolved with the development of independently led outreach Rheumatology Practitioner (RP) clinics in Primary Care (PC). Their clinical and cost effectiveness, compared with Secondary Care (SC) services, has not been assessed. The RECIPROCATE study aims to evaluate their clinical and cost effectiveness. This part of the study aimed to explore health professionals’ opinions of rheumatology outreach service. Methods Using a qualitative design, semi-structured interviews were conducted with GPs, practice nurses, hospital doctors and RPs, from one hospital and seven PC practices in Norfolk, to elicit their opinions of the service. The interviews were analysed using thematic analysis. Results All participants agreed the service was supportive and valuable providing high quality personalised care, disease management, social, and educational support. Advantages identified included convenience, continuity of care and proximity of services to home. RPs helped bridge the communication gap between PC and SC. Some participants suggested having a doctor alongside RPs. The service was considered to be cost effective for patients but there was uncertainty about cost effectiveness for service providers. Few disadvantages were identified the most recurring being the lack of other onsite services when needed. It was noted that more services could be provided by RPs such as prescribing and joint injections as well as playing a more active role in knowledge transfer to PC. Conclusions Professionals involved in the care of RA patients recognised the valuable role of the RP outreach clinics. This service can be further developed in rheumatology and the example can be replicated for other chronic conditions. PMID:22607063

    Restricted and repetitive behaviours (RRB) represent a common problem throughout the autistic spectrum. They comprise a wide range of behavioural manifestations that persist over time and resist therapeutics. Furthermore, degrees of heterogeneity have been reported in the clinical expression of autistic syndrome, particularly in the restricted and repetitive aspects. Advances are needed in the understanding of this complex and heterogeneous clinical dimension of autism to improve efficacy of therapeutics. Most clinical studies have subdivided RRB into "lower-level" sensory-motor behaviours and "higher-level" behaviours, which are more complex and characteristic features of autism. However, none of these studies have taken into account all the forms of RRB. To date, there is no specific and thorough tool to evaluate this dimension of autism. From the analysis of the literature, we proposed a list of 43 behaviours covering the full range of repetitive, restricted and stereotyped activities observed in autism. The aim of the present study was to test the relevance of these 43 RRB in a family context. The participants were 14 children with an autism spectrum disorder, aged from six to 16 years. Circumscribed interests were the most commonly reported RRB, and motor stereotypies, aggressive and body-focused behaviours were the least expressed behaviours. Multivariate statistical analysis identified three groups of children with different behavioural profiles and three clusters of RRB, i.e. repetitive motor behaviours, repetitive sensory-vocal behaviours and restricted ideational behaviours. Although these preliminary results need to be validated in a wider population, the list of 43 RRB allowed us to describe accurately this symptomatology of autism and to confirm the heterogeneity of this dimension of autistic disorders. The identification of clinical subgroups, possibly underlain by different psychopathological or physiopathological factors would help research and

    To implement and evaluate a series of interactive clinically applied anatomy tutorials for final year dental undergraduate students. A 6-week voluntary virtual program of tutorials for final year dental undergraduates, with pre- and post-tutorial testing, was evaluated using a priority sequence model (QualQuan). A purposive sample (n = 15) was taken of the year group (n = 69) and the initial qualitative phase in depth interviews were carried out until data saturation (n = 13). The emergent recurrent themes from the qualitative data were then phrased into a variety of non-leading questions. These questions were issued in the form of an anonymous electronic questionnaire to the whole student body. There was a good uptake of the tutorials with 84% of the students accessing at least one tutorial before sitting their final examinations. A response rate of 70% was achieved for the quantitative evaluative questionnaire phase of the study. Overall perceptions of the course were favourable although a number of modifications were suggested. These included a more concise presentation of the mainstream tutorial text with hyper links to more detailed content. Students also indicated a desire for more line diagrams. These changes, it was suggested, would help with the on-line readability of the tutorials. The primary focus for the students' learning appeared to be provided by the pre- and post-tutorial tests even though explicit learning outcomes were provided for each tutorial. This study demonstrates that a well-designed virtual course can help to vertically integrate, and make clinically relevant, one of the basic sciences underpinning dental surgery. It has shown that formative assessment acts as a powerful tool to focus student attention and direct student learning. This leads to the conclusion that formative assessments have to be designed with as much care and attention as summative assessments.

    The aims of the study were to determine the prevalence of variations in the recorded outcomes of clinical evaluations by 2 different physicians during a single patient visit and to comment on observations of physician practices regarding history taking and physical examination. Structured interviews were conducted with both junior and supervising physicians after they had evaluated patients in a pediatric emergency department who presented with complaints of fever (temperature, >100.4°F) in infants younger than 3 months, fever (temperature, >102.2°F) in infants aged 3 to 12 months, headache in patients older than 5 years, abdominal pain in patients older than 5 years, and head injury in patients younger than 18 years. Data were analyzed with descriptive statistics. Most of the data reported by both junior and supervising physicians showed response disagreement. The questions on fever (temperature, >102.2°F) in infants aged 3 to 12 months showed 29% (10/34) disagreement on fever duration and 45% (5/11) on fever height. Questions on abdominal pain in children older than 5 years showed 24% (24/100) disagreement on reporting right lower quadrant pain and 10% (11/106) on right lower quadrant tenderness on examination; however, the discrepancy rates were 56% (56/100) when considering less than complete agreement on all painful sites and 53% (56/106) on all tender sites. Supervising physicians questioned and examined patients presenting with abdominal pain more often than those presenting with other complaints. There are significant variations in the recorded outcome of clinical evaluations by 2 different physicians during a single patient visit. Supervising physicians are more cautious to question and examine patients presenting with abdominal pain compared with other chief complaints.

    Noninvasive objective evaluation of nasal airflow is one of the important clinical aspects. The developed polyvinylidene fluoride (PVDF) sensor enables measurement of airflow through each side of the nose using its piezoelectric property. This study was designed to evaluate the diagnostic capability of the PVDF sensor in assessing the deviated nasal septum (DNS). PVDF nasal sensor uses its piezoelectric property to measure the peak-to-peak amplitude (Vp-p) of nasal airflow in both of the nostrils: right nostril (RN) and left nostril (LN), separately and simultaneously. We have compared the results of PVDF nasal sensor, visual analog scale (VAS), and clinician scale for 34 DNS patients and 28 healthy controls. Additionally, the results were further analyzed by receiver operating characteristic curve and correlation between PVDF nasal sensor and VAS in detecting DNS. We found a significant difference in the peak-to-peak amplitude values of the test group and the control group. The correlation between the PVDF nasal sensor measurements and VAS (RN and LN combined) for test group was statistically significant (−0.807; p < 0.001). Sensitivity and specificity of the PVDF nasal sensor measurements in the detection of DNS (RN and LN combined) was 85.3 and 74.4%, respectively, with optimum cutoff value ≤0.34 Vp-p. The developed PVDF nasal sensor is noninvasive and requires less patient efforts. The sensitivity and specificity of the PVDF nasal sensor are reliable. According to our findings, we propose that the said PVDF nasal sensor can be used as a new diagnostic tool to evaluate the DNS in routine clinical practice. PMID:24498519

    We previously conducted a multicenter study enrolling 101 dialysis patients with hyperphosphatemia in which lanthanum carbonate (LC) was administered for 2 years. In this study, the administration has been continued for an additional year, and we have evaluated the long-term (a total of 3 years) effects of LC. The average serum phosphorus (P) level was 6.05 mg/dL at the start and decreased to 5.84 mg/dL after 3 years, but no significant differences were observed at both points. The average serum corrected calcium (Ca) level significantly reduced after 3 years (P < 0.001). As results of evaluating the achievement rates with the management target values of serum P, Ca and intact parathyroid hormone (PTH) stated in the Japanese guideline, the achievement rates increased after 3 years. From these results, LC is considered to be a useful P binder that can be used for long-term treatment of hyperphosphatemia, without causing a Ca load.

    This study assesses the failure rate of soft-tissue versus hardware fixation of biceps tenodesis by ultrasound to determine if the expense of a hardware tenodesis technique is warranted. Seventy-two patients that underwent arthroscopic biceps tenodesis over a 3-year period were evaluated using postoperative ultrasonography and clinical examination. The tenodesis technique employed was either a soft-tissue technique with sutures or an interference screw technique using hardware based on surgeon preference. Patient age was 57.9 years on average with ultrasound and clinical examination done at an average of 9.3 months postoperatively. Thirty-one patients had a hardware technique and 41 a soft-tissue technique. Overall, 67.7% of biceps tenodesis done with hardware were intact, compared with 75.6% for the soft-tissue technique by ultrasound (P = .46). Clinical evaluation indicated that 80.7% of hardware techniques and 78% of soft-tissue techniques were intact. Average material cost to the hospital for the hardware technique was $514.32, compared with $32.05 for the soft-tissue technique. Biceps tenodesis success, as determined by clinical deformity and ultrasound, was not improved using hardware as compared to soft-tissue techniques. Soft-tissue techniques are equally efficacious and more cost effective than hardware techniques.

    Early-life antibiotic exposure, whether through prenatal or childhood antibiotic use, may contribute to increased child body mass. Associations of prenatal and childhood antibiotic use with body mass index z-score (BMIz) were evaluated at age 3 years. Electronic health records were utilized from 8,793 mothers and singleton children delivered at Geisinger Clinic in Pennsylvania between 2006 and 2012. Antibiotic orders were ascertained for mothers during pregnancy and for children through their age-3 BMI measurement. Linear mixed-effects regression models evaluated associations of prenatal and childhood antibiotic use with child BMIz. Prenatal antibiotic orders were not associated with child BMIz. Children in the three largest categories of lifetime antibiotic orders had higher BMIz compared with children with no orders; associations persisted when controlling for prenatal antibiotics (β [95% confidence interval]) (4-5 child orders: 0.090 [0.011 to 0.170]; 6 to 8: 0.113 [0.029 to 0.197]; ≥9: 0.175 [0.088 to 0.263]; trend P value <0.001). Two or more first-year orders were also associated with BMIz (1: 0.021 [-0.038 to 0.081]; 2: 0.088 [0.017 to 0.160]; ≥3: 0.104 [0.038 to 0.170]; trend P value < 0.001). Associations of early-life and lifetime childhood antibiotic use with increased child BMI highlight antibiotic exposure as a modifiable factor for reducing population-level excess weight. © 2017 The Obesity Society.

    Many fillers have been used to augment lips. Agarose gel is a new and absorbable filler indicated for the correction of soft tissues and lip. This article reviews the results of 68 cases that have undergone lip augmentation with this new filler in the last 3 years. A total of 68 patients received agarose gel for treatment for lip augmentation in a 3-year period from 2005 to 2008. Each of the patients signed an informed consent form. The patients were between 35 and 70 years of age. Three patients were male, and 65 were female. A volume of 0.5-1.0 mL of agarose gel was sufficient for each lip. A bigger volume may result in a dense mass and pain. All patients were successfully treated with injections of agarose gel. Clinical improvement was noted immediately, and only mild bruising was recorded. All of the the patients returned to the clinic 10 days after treatment for follow-up, and all felt that an excellent cosmetic result was obtained. The patients were told to return after an additional month for follow-up and possible reinjection. The results lasted approximately 5 months with a gradual decline to baseline. The agarose gel was very well tolerated with only a few mild adverse reactions that resolved spontaneously. During 3 years of clinical use, agarose gel proved to be a reliable and predictable treatment for lip augmentation.

    The monitoring of ionic dialysance in hemodialysis allows early detection of arterio-venous fistula stenosis. One limitation to the practical use of ionic dialysance is that the analysis is very time consuming on a majority of normal cases.The purpose of the study is to evaluate the utility of an expert system reproducing a human analysis and allowing continuous monitoring of the ionic dialysance by helping the physician to focus his or her expertise on the abnormal cases.The method is based on a Bayesian model that analyzes the blood flow rate, the ionic dialysance, and the venous and arterial pressures measured on the extra corporeal circuit.The clinical evaluation was performed on 90 dialysis patients at the hospital dialysis center of Saint Brieux in France with a history of at least four consecutive months of validated recording. The retrospective automated analysis was evaluated in comparison to vascular access problems identified from invasive investigation or treatment. The sensitivity of the automated analysis is 92% with a specificity of 75%.As a conclusion we suggest that this expert system could be used in a continuous vascular access monitoring procedure consisting in a weekly review of the patient population at the dialysis center. The patients with the highest risk score need a further investigation of their historical data and their medical history in order to decide whether or not to perform an invasive intervention.

    The purpose of this study was to evaluate an Objective Structured Clinical Examination (OSCE) designed to examine all six competencies and provide meaningful results to improve resident performance. A prospective, observational study. The OSCE consists of 1 hour for examination of a simulated patient, documentation, and feedback, with 30 minutes for an evidence-based medicine (EBM) test. Eight otolaryngology residents participated. Digital recordings and written documentation were evaluated on all competencies except practice-based learning. An EBM test was scored to assess practice-based learning. Overall, senior residents scored better. Seniors scored better on performing a focused history, whereas juniors scored better for thoroughness. Seniors coded better than juniors, although seniors tended to undercode and juniors tended to overcode. Two cases of "insurance fraud" were also discovered. The "Six Pack" successfully evaluated all competencies while providing valuable information. A clinical practicum was added to improve history and physical examination skills. The discussion of coding and a billing seminar also resulted. Residents believed the OSCE was valuable. Faculty members were impressed with the useful information obtained.

    This article reviews current evidence for autism spectrum disorder (ASD) interventions for children aged <3 years, based on peer-reviewed articles published up to December 2013. Several groups have adapted treatments initially designed for older, preschool-aged children with ASD, integrating best practice in behavioral teaching methods into a developmental framework based on current scientific understanding of how infants and toddlers learn. The central role of parents has been emphasized, and interventions are designed to incorporate learning opportunities into everyday activities, capitalize on "teachable moments," and facilitate the generalization of skills beyond the familiar home setting. Our review identified several comprehensive and targeted treatment models with evidence of clear benefits. Although some trials were limited to 8- to 12-week outcome data, enhanced outcomes associated with some interventions were evaluated over periods as long as 2 years. Based on this review, recommendations are proposed for clinical practice and future research.

    There is lack of knowledge about the clinical performance of computer-aided design/computer-aided manufacturing (CAD/CAM) titanium-ceramic-fixed partial dentures (FPDs). The purpose of this study was to evaluate CAD/CAM titanium-ceramic FPDs after 3 years in function. Thirty-one FPDs were fabricated for 23 patients. The Ti frameworks were completely fabricated using CAD/CAM technology, and the low-fusing porcelain was veneered. After confirming there were no mechanical or biological complications, the FPDs were cemented using zinc phosphate cement. The patients were recalled at 12, 24, and 36 months after cementation to examine for the presence of any mechanical complications, such as fractures of the veneering porcelain or the supportive framework, or biological complications, including caries, gingivitis, or periodontitis. The periodontal condition was measured using probing depth (PD), bleeding on probing (BOP), and plaque index (PI). Success and survival rates were estimated using the Kaplan-Meier analysis. There were four cohesive and three adhesive porcelain fractures, but no framework fractured. The Kaplan-Meier cumulative success rate of the CAD/CAM titanium-ceramic crown with regard to mechanical complications was 76.4%, and the cumulative survival rate was 96.8% after 3 years of use. One patient developed caries, but the condition was not associated with marginal discrepancy. No other biological complications were reported. The periodontal parameters demonstrated a tendency that slightly increased up to 24 months and was maintained by 36 months. At the end of the follow-up, PD was 2.86 mm, percentile of surface with BOP was 23.5, and PI was 0.45. The CAD/CAM titanium-ceramic FPDs survived in the mouths of patients without major complications for 3 years, although the risk of porcelain fracture appeared to be relatively high. © 2010 by The American College of Prosthodontists.

    Until 1960, 179 cases of infection with Nocardia asteroides had been described in the world literature. Seventeen cases in children were reported by 1963. The organism is a common saprophyte in nature with probably a world-wide distribution. Infection can be primary but is more common in patients with underlying malignancy, auto-immune disease or preceding tuberculosis. Sulphonamides, particularly sulphadiazine, are the drugs of choice in treatment; the value of antibiotics is less clearly established. The indications for surgical treatment have not yet been defined. We record a further case of primary pulmonary nocardiosis in a 3-year-old child. Images PMID:6035802

    The admissions interview still remains the most common approach used to describe candidates' noncognitive attributes for medical school. In this prospective study, we have investigated the predictive validity of a semi-structured interview for admissions to medical school based on medical judgment vignettes: (1) ethical decision-making (moral), (2) relationships with patients and their families (altruistic), and (3) roles and responsibilities in professional relationships (dutiful). A group of 26 medical students from the Class of 2007 participated in the interview process and provided their subsequent performance results from clerkship 3 years later. Inter-rater reliability of the scored interviews was high (kappa = 0.96). Our results provided evidence for both convergent and divergent predictive validity. Medical judgment vignettes scores correlated significantly with seven mandatory clerkship rotation in-training evaluation reports (r = 0.39, p < 0.05; to r = 0.55, p < 0.01). This semi-structured interview based on clearly defined and scored medical judgment vignettes that focus on the assessment of medical students' noncognitive attributes is promising for student's selection into medical school. The high reliability and evidence of predictive validity of clinical performance over a 3-year period suggests a workable approach to the assessment of 'compelling personal characteristics' beyond merely cognitive variables.

    The main aim of this study is to validate the Acuros XB dose calculation algorithm for a Varian Clinac iX linac in our clinics, and subsequently compare it with the wildely used AAA algorithm. The source models for both Acuros XB and AAA were configured by importing the same measured beam data into Eclipse treatment planning system. Both algorithms were validated by comparing calculated dose with measured dose on a homogeneous water phantom for field sizes ranging from 6 cm × 6 cm to 40 cm × 40 cm. Central axis and off-axis points with different depths were chosen for the comparison. In addition, the accuracy of Acuros was evaluated for wedge fields with wedge angles from 15 to 60°. Similarly, variable field sizes for an inhomogeneous phantom were chosen to validate the Acuros algorithm. In addition, doses calculated by Acuros and AAA at the center of lung equivalent tissue from three different VMAT plans were compared to the ion chamber measured doses in QUASAR phantom, and the calculated dose distributions by the two algorithms and their differences on patients were compared. Computation time on VMAT plans was also evaluated for Acuros and AAA. Differences between dose-to-water (calculated by AAA and Acuros XB) and dose-to-medium (calculated by Acuros XB) on patient plans were compared and evaluated. For open 6 MV photon beams on the homogeneous water phantom, both Acuros XB and AAA calculations were within 1% of measurements. For 23 MV photon beams, the calculated doses were within 1.5% of measured doses for Acuros XB and 2% for AAA. Testing on the inhomogeneous phantom demonstrated that AAA overestimated doses by up to 8.96% at a point close to lung/solid water interface, while Acuros XB reduced that to 1.64%. The test on QUASAR phantom showed that Acuros achieved better agreement in lung equivalent tissue while AAA underestimated dose for all VMAT plans by up to 2.7%. Acuros XB computation time was about three times faster than AAA for VMAT plans, and

    The purpose of this study was to evaluate a modified test of equivalence for conducting normative comparisons when distribution shapes are non-normal and variances are unequal. A Monte Carlo study was used to compare the empirical Type I error rates and power of the proposed Schuirmann-Yuen test of equivalence, which utilizes trimmed means, with that of the previously recommended Schuirmann and Schuirmann-Welch tests of equivalence when the assumptions of normality and variance homogeneity are satisfied, as well as when they are not satisfied. The empirical Type I error rates of the Schuirmann-Yuen were much closer to the nominal α level than those of the Schuirmann or Schuirmann-Welch tests, and the power of the Schuirmann-Yuen was substantially greater than that of the Schuirmann or Schuirmann-Welch tests when distributions were skewed or outliers were present. The Schuirmann-Yuen test is recommended for assessing clinical significance with normative comparisons.

    Patients with chronic kidney disease (CKD) exhibit an increased cancer risk compared to a healthy control population. To be able to estimate the cancer risk of the patients and to assess the impact of interventional therapies thereon, it is of particular interest to measure the patients' burden of genomic damage. Chromosomal abnormalities, reduced DNA repair, and DNA lesions were found indeed in cells of patients with CKD. Biomarkers for DNA damage measurable in easily accessible cells like peripheral blood lymphocytes are chromosomal aberrations, structural DNA lesions, and oxidatively modified DNA bases. In this review the most common methods quantifying the three parameters mentioned above, the cytokinesis-block micronucleus assay, the comet assay, and the quantification of 8-oxo-7,8-dihydro-2′-deoxyguanosine, are evaluated concerning the feasibility of the analysis and regarding the marker's potential to predict clinical outcomes.

    This study aimed to clinically evaluate the disinfection efficacy of chlorine dioxide (ClO2) for used dental instruments. An imprint culture technique demonstrated that ultrasonic cleaning of intraorally applied dental mirrors in 0.02% ClO2 for 10 minutes resulted in compete removal of microorganisms for 10 subjects. Hepatitis C virus (HCV) RNA was detected by real-time polymerase chain reaction on periodontal curettes after subgingival scaling in four HCV-infected patients and was completely removed by the same treatment procedure. Therefore, the combination of ultrasonic cleaning with ClO2 may provide an alternative to toxic disinfectants, such as glutaraldehyde and sodium hypochlorite, for disinfecting dental instruments.

    The prevalence of neurodegenerative diseases such as Parkinson disease (PD) will increase substantially, due to the aging of the population and improved treatments leading to better disease-related outcomes. Dementia is the most common nonmotor symptom in PD, and most patients with PD will have cognitive dysfunction and cognitive decline in the course of their disease. The development of cognitive dysfunction in PD greatly limits the ability to participate in activities of daily living and can be a tipping point for nursing home placement or major caregiver stress. Understanding the different causes of dementia and how to reduce the incidence and impact of secondary cognitive dysfunction in PD are necessary skills for primary care physicians and neurologists. In this review, we discuss the clinical epidemiology of dementia in PD with an emphasis on preventable cognitive dysfunction, present tools for outpatient evaluation of cognitive dysfunction, and describe current pharmacological treatments for dementia in PD. © The Author(s) 2016.

    Patients with contact dermatitis require both preventive and therapeutic interventions to minimize their burden of disease. The ideal product would support resolution of inflamed skin without the use of glucocorticoids while protecting undamaged skin against further contact with irritants and antigens. COR806.805 (Tetrix Cream) is a novel barrier cream formulated for use on both lesional and nonlesional skin. Three clinical trials were conducted to evaluate the safety of this new product by studying sensitization, cumulative irritation, and effect on healing; a combined total of 265 participants completed the studies (210, 45, and 10, respectively), with no serious adverse events considered to be related to the product. Six mild adverse events were considered related or potentially related. As tested, COR806.805 is neither sensitizing nor irritating when applied to intact or lesional skin. Testing indicates that COR806.805 does not inhibit healing of allergic contact dermatitis lesions.

    The efficacy and safety of the broad-spectrum, topically applied antifungal agent clotrimazole were evaluated in two double-blind, multicentric trials. Ten investigators reported on a total of 1,361 cases in which a 1% solution or a 1% cream formulation was compared with its respective vehicle. Clotrimazole was therapeutically effective, as confirmed by mycological cure (negative microscopy and culture) and clinical improvement, in tinea pedis, tinea cruris, tinea corporis, pityriasis versicolor, and cutaneous candidasis. Furthermore, species identification established the efficacy of clotrimazole against Trichophyton rubrum, T mentagrophytes, Epidermophyton floccosum, Microsporum canis, Malassezia furfur (Pityrosporum orbiculare), and Candida albicans. Safety was demonstrated by the low incidence of possibly drug-related adverse experiences, namely, 19 (2.7%) of 699 patients who were treated with clotrimazole, of whom four (0.6%) discontinued treatment.

    To evaluate the clinical outcome of periapical endodontic surgery for teeth that can't be treated by nonsurgical endodontic methods. Sixty-two affected teeth were chosen for surgical endodontic treatment, of which 31 teeth underwent periapical curettage and the others were treated by root-end resection, retrograde preparation and filling. A radiography was taken immediately after surgery and was compared with those taken at 12 and 24 months. The results of two groups were analyzed using the chi2 test. The success rate for retrograde filling was higher (85% after 12 months, 88% after 24 months) compared with that of periapical curettage (52% after 12 months, 45% after 24 months). The difference in success rate between the two groups was statistically significant. Ultrasonic root-end preparation and retrograde filling is a good choice of treatment when the teeth can't be treated appropriately by nonsurgical treatment.

    Chronic Musculoskeletal Pain (MSP) in children can be due to non-inflammatory conditions, such as the benign joint hypermobility syndrome (BJHS) or idiopathic MSP (IMSP). Aim of the study was to evaluate type and persistence of MSP in a cohort of schoolchildren with MSP followed for 3 years, in order to identify the main risk factors. Healthy schoolchildren, aged 8-13 years, underwent a general and rheumatologic examination, focusing on presence of chronic MSP, defined as continuous or recurrent pain lasting more than 3 months and heavily interfering with daily life activities, presence of generalized joint hypermobility, the body mass index and the pubertal stage. All symptomatic subjects were re-evaluated 3 years later with the same methods. Seventy of the 88 symptomatic subjects of the initial cohort of 289 were re-evaluated 3 years later. Of these, 38 (54.3 %) still presented MSP, including 19 with BJHS and 19 with IMSP. Main symptoms were lower limbs arthralgia and myalgia. MSP persisted more in females than in males (p = 0.038) and in pubertal rather than pre-pubertal subjects (p = 0.022); these subjects recovered significantly more both from BJHS (p = 0.004) and IMSP (p = 0.016). Gender did not influence the distribution of MSP according to pubertal stage. Female gender, BJHS and pubertal stage are important risk factors for persistence of MSP. Further studies are needed to evaluate the natural history of MSP towards adulthood and the role of the pubertal age.

    Chronic urticaria (CU) is a skin disorder defined as daily or almost daily exhibition of pruritic and transient wheals that last for 6 weeks. CU is divided into two subtypes: chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU). To evaluate the clinical features, possible causes, associated findings, and laboratory results of different subtypes of CU in children according to a new classification. In this study, we evaluated the clinical features, laboratory investigations, and provocation tests of children with different subtypes of CU according to a new classification. Two hundred and twenty-two children (59.9% girls) were enrolled in the study. Of the study patients, 59.9% and 40.1% were diagnosed as having CSU and CIndU, respectively. Antithyroid antibody levels were positive in 7.1% of the patients with CSU, 32.8% of the children had positive 14C-urea breath test results, and 6.5% of the patients had positive stool examination results for parasites. Autologous serum skin test results were positive in 53.5% of the patients with CSU. Of the patients with CIndU, 77.5% had symptomatic dermographism, 16.8% had cold urticaria, 2.2% had cholinergic urticaria, 2.2% had solar urticaria, and 1.1% had aquagenic urticaria. Children with CSU represent the majority of patients with CU, and more than a half of these patients might have autoimmune urticaria. Symptomatic dermographism was the most common type of CIndU.

    OBJECTIVE The long-term effectiveness of endovascular treatment of large and giant wide-neck aneurysms using traditional endovascular techniques has been disappointing, with high recanalization and re-treatment rates. Flow diversion with the Pipeline Embolization Device (PED) has been recently used as a stand-alone therapy for complex aneurysms, showing significant improvement in effectiveness while demonstrating a similar safety profile to stent-supported coil treatment. However, relatively little is known about its long-term safety and effectiveness. Here the authors report on the 3-year safety and effectiveness of flow diversion with the PED in a prospective cohort of patients with large and giant internal carotid artery aneurysms enrolled in the Pipeline for Uncoilable or Failed Aneurysms (PUFS) trial. METHODS The PUFS trial is a prospective study of 107 patients with 109 aneurysms treated with the PED. Primary effectiveness and safety end points were demonstrated based on independently monitored 180-day clinical and angiographic data. Patients were enrolled in a long-term follow-up protocol including 1-, 3-, and 5-year clinical and imaging follow-up. In this paper, the authors report the midstudy (3-year) effectiveness and safety data. RESULTS At 3 years posttreatment, 74 subjects with 76 aneurysms underwent catheter angiography as required per protocol. Overall, complete angiographic aneurysm occlusion was observed in 71 of these 76 aneurysms (93.4% cure rate). Five aneurysms were re-treated, using either coils or additional PEDs, for failure to occlude, and 3 of these 5 were cured by the 3-year follow-up. Angiographic cure with one or two treatments of Pipeline embolization alone was therefore achieved in 92.1%. No recanalization of a previously completely occluded aneurysm was noted on the 3-year angiograms. There were 3 (2.6%) delayed device- or aneurysm-related serious adverse events, none of which led to permanent neurological sequelae. No major or minor

    Osteogenesis Imperfecta (OI) is a genetic disease, in which the main clinical features are increased bone fragility, pathological fractures, blue sclera, dentinogenesis imperfecta and conductive or mixed hearing loss. Clinical variability is wide. Although there is no curative treatment, there are several therapeutic tools capable of improving the course of the condition and patient quality of life. Sixty-five children seen in a Paediatric Hospital during six months in 2007 were evaluated. Thirty-five were type I OI, and thirty were types III-IV. Median age was 7.8 years (range 1.9-19.2); mean length of follow up was 4.7 years. The majority of children attended regular school for their corresponding age. Mean height was -1.4 sDS and -5.64 sDS in types I and III-IV respectively. Nineteen percent of patients were overweight and 11% were obese. Mean age at first orthopaedic surgery inserting telescopic rods was 6.5 years. Scoliosis was present in 44.6% of patients and was directly related to severity. Bleck's motor scale showed that 93% of patients with mild forms and 29% of severe forms had a sustainable walking ability. A wheelchair was used by 25% of patients. Family inheritance was confirmed in 65% of cases. Integral care using a multidisciplinary approach is required due to the complexity and clinical variability of the condition.

    To measure tooth whitening effects delivered immediately after brushing with silica-based toothpastes containing either blue covarine or a combination of blue covarine and FD&C Blue No. 1 in vitro and in vivo. Salivary pellicle coated human extracted teeth were brushed with either a slurry of a toothpaste containing blue covarine (BC) or a formulation containing a matched level of blue covarine and FD&C Blue No.1 (BC+D). The colour of the specimens were measured in vitro using a colorimeter, before and after brushing and changes in CIELAB and tooth Whiteness Index (WIO) values calculated. In a double-blind cross-over clinical study, subjects brushed with BC toothpaste, a toothpaste containing increased levels of blue covarine (BC+) or BC+D toothpaste and tooth colour changes were measured with a digital image analysis system. The in vitro study demonstrated that BC+D gave a significantly (p=0.002) greater change in WIO value than BC. Clinical results showed that BC, BC+ and BC+D gave a significant increase in WIO (p<0.0001) from baseline. The WIO change was significantly greater when brushing with BC+D toothpaste than with either toothpaste BC (p<0.0001) or BC+ (p<0.05). Toothpastes containing blue covarine or a combination of blue covarine and FD&C Blue No. 1 gave a statistically significant improvement in tooth whiteness immediately after brushing in both in vitro and clinical studies. In addition, the toothpaste containing both blue covarine and FD&C Blue No. 1 gave statistically significant greater tooth whitening from baseline than the blue covarine containing toothpastes. The silica-based toothpastes containing blue covarine or a combination of blue covarine and FD&C Blue No. 1 evaluated in the current study gave significant tooth whitening benefits immediately after one brush.

    Initial symptoms of Rocky Mountain spotted fever (RMSF), a tick-borne illness caused by Rickettsia rickettsii, are nonspecific and include headache, gastrointestinal disturbances, malaise, and myalgias, followed by fever and rash. The classic triad of fever, rash, and history of tick exposure is uncommon at presentation. Clinical manifestations of RMSF range from virtually asymptomatic to severe. Because of the potentially fatal outcome of RMSF, presumptive clinical diagnosis and empiric antimicrobial therapy can be critical. We present the case of a 3-year-old girl from New York State who presented with fever and rash.

    We examined the clinical course and the prognosis of patients with anti-NMDAR encephalitis. We retrospectively evaluated the patients who has distinctive clinical features as anti-NMDAR encephalitis based on their medical records. There were two male and four female patients with anti-NMDAR encephalitis. They were aged between 13 and 16 years. One of the six, 14 years female patient was negative for anti-NMDAR antibody. All four female patients with anti-NMDAR encephalitis had an ovarian tumor. Neurocognitive dysfunction and epilepsy remained in one female patient with right temporal lobe lesion and one male patient with celebellar abnormalities had mild mental impairment. In three patients including two patients who were examined abdominal MRI for the first time after recovery from the encephalitis, overian tumors became apparent during follow-up. In one of other patients, overian tumors had a tendency to increase in size after recovery. Sequellae were seen in two cases that have abnormalities in brain MRI. As to ovarian tumor, it was considered to be necessary to checkup pelvic MRI for at least four years after the onset of encephalitis.

    Diabetic polyneuropathy (DPN) is a major cause of neuropathic pain and a frequent target condition in analgesic treatment trials. Differences in the clinical symptoms and signs associated with DPN suggest distinct pathophysiological mechanisms underlying nerve damage and dysfunction that are likely to have therapeutic relevance. The aim of this study was to develop a tool for the bedside assessment of painful neuropathies such as DPN that captures the diversity of phenotypes. Sixty-one patients with type 2 diabetes and painful neuropathy, 19 patients with painless DPN, 25 patients with type 2 diabetes but no clinical evidence of neuropathy, and 20 healthy control subjects completed a structured interview (47 items) and a standardized physical examination (39 items). After analyzing critical features of pain and painless symptoms and examining the outcome of physical tests of sensory function, we determined principal components of the phenotypic variance among patients. Increased sensitivity to mechanical or thermal stimuli and, to a lesser extent, the sensory quality of pain or paresthesia were the most discriminating elements of DPN phenotypes. Correlation patterns of symptoms and signs indicated the involvement of functionally distinct nerve fiber populations. We combined interview questions and physical tests identifying these differences in a shortened assessment protocol that we named Standardized Evaluation of Pain and Somatosensory Function (StEPS). The protocol StEPS generates a phenotypic profile of patients with neuropathy. Separate intensity ratings for spontaneous painful symptoms and pain evoked by standard stimuli support a detailed documentation of neuropathic pain and its response to analgesic treatment.

    The rapid development and clinical use of digital mammography in the past decade has made possible the development of digital breast tomosynthesis (DBT), which can overcome the limitation of conventional mammography and improve the specificity of mammography with improved marginal visibility of lesion and early breast cancer detection, especially for women with dense breast. The purpose of this study is to characterize the physical properties of DBT system and to optimize the exposure condition using effective modulation transfer function (eMTF), effective noise power spectrum (eNPS), and effective detective quantum efficiency (eDQE). The first generation KERI prototype digital tomosyntesis system for breast imaging using CMOS flat panel detector was used in this study. It was found that the spatial frequency dependent metrics depend on both the inherent properties of the detector and imaging geometry including breast thickness. For thicker breast, eDQE decreases as scatter fraction increases at fixed tube voltage. Moreover, eMTF shows no significant difference as changing tube voltage while eDQE at 27 kVp is relatively degraded. Consequently, the quantitative evaluation of the DBT system with different exposure condition and breast thickness should be fully considered before building the system and application in clinical hospital.

    Forty-two pediatric patients were treated with ceftazidime ( CAZ ) in the doses ranging from 45.6 to 120 mg/kg/day for 2 to 10 days, and the clinical efficacy and side effects were evaluated. Among the 37 children with bacterial infections including pneumonia, bronchitis, tonsillitis, croup, cervical lymphadenitis, abdominal abscess and urinary tract infections, the results were excellent in 22, good in 12, fair in 2, and poor in 1 patient with pneumonia. Out of the 42 patients, 5 cases showed eosinophilia, but no clinical sign such as rash, fever or diarrhea, attributable to CAZ was observed during the study. The serum concentrations of CAZ in 4 patients ranged from 60.8 to 71.0 micrograms/ml (mean 66.1 micrograms/ml) at 30 minutes and from 0.5 to 1.2 micrograms/ml (mean 0.8 micrograms/ml) at 8 hours after 20 mg/kg intravenous bolus injection of the antibiotic. The mean serum half-life was 1.42 hours (85 minutes). Patients with impairment of renal function were excluded from this study.

    This randomized controlled clinical trial was conducted to determine the effectiveness and safety of a new whitening dentifrice. One hundred eighty-two qualifying subjects were randomly assigned to either a whitening dentifrice group (Arm & Hammer Truly Radiant Toothpaste), a negative control dentifrice group (Colgate Cavity Protection Toothpaste), or a positive control dentifrice group (Crest 3-D White Radiant Mint Toothpaste) and were instructed to brush twice daily with their assigned dentifrice for six weeks. Extrinsic tooth stain was assessed using a Modified Lobene Stain Index (MLSI) and tooth shade was assessed using the VITA Classic Shade Guide at baseline and after five days and two, four, and six weeks of dentifrice use. Safety was monitored by clinical examinations and panelist assessment at each evaluation period. The Arm & Hammer Truly Radiant group showed a statistically significant improvement from baseline in mean composite MLSI and VITA shade at each examination period (p < 0.0001). Significant improvements on day 5 progressively increased with increasing duration of product use. By week 6, there was a 45.4% reduction in stain and a 2.08 improvement in tooth shade. The between-group comparison revealed that Truly Radiant toothpaste was significantly more effective than both the negative and positive control dentifrices for these parameters (p < 0.0001) at each exam time. This study showed that the new dentifrice formulation is safe and effective on stain removal and tooth whitening.

    The Konelab 20XT (Thermo Electron Oy, Finland) is a clinical chemistry analyzer for colorimetric, immunoturbidimetric and ion-selective electrode measurements. The aim of our work was to evaluate the analytical performances of the Konelab 20XT according to the European Clinical Chemistry Laboratory Standards Guidelines. A total of 30 analytes including substrates, enzymes, electrolytes and specific proteins were tested. Investigation results showed low imprecision (within-run coefficient of variation was below 3.5% and between-day coefficient of variation was less than 2.5% for most analytes at all three levels studied) and acceptable accuracy of the analyzer. No significant sample- or reagent-related carry-over was found. It was demonstrated that the analytical system operates within the claimed linearity ranges. The results compared well with those obtained by instruments routinely used in our laboratory (Olympus AU2700, Behring Nephelometer II). In general, the data on interference by hemoglobin, hyperbilirubinemia and turbidity are in accordance with known facts. However, slight hemolysis was found to interfere with the alkaline phosphatase (ALP) assay and mild lipemia affected the glucose assay. The Konelab 20XT is an easy-to-use analyzer that is suitable for routine and emergency analyses in small laboratories.

    Antemortem studies pertaining to the manatee cardiovascular and cardiopulmonary systems are limited despite reports of cardiac disease in postmortem specimens. The objective of this project was to develop a technique for echocardiography in the Florida manatee (Trichechus manatus latirostris). Because of their unique anatomy, a ventral approach was employed by use of an echocardiography table designed specifically for this study. Fourteen clinically healthy, free-ranging and captive Florida manatees underwent echocardiography between the fall of 2011 and winter of 2012. Eight females and six males of various age categories were included in the study. Clear visualization of all valves and chambers was accomplished, and length and width measurements of the left atrium, peak aortic flow velocity, and ejection fraction percentage were calculated in most animals. Abnormalities observed during the study included atrioventricular regurgitation and severe right-atrial enlargement. Based on the results of this study, echocardiography in the Florida manatee is possible, which has both clinical and research implications in larger epidemiologic studies evaluating diseases of the cardiopulmonary and cardiovascular systems.

    Smith-Magenis syndrome (SMS) is a complex congenital anomaly characterized by craniofacial anomalies, neurological and behavioral disorders. SMS is caused by a deletion in region 17p11.2, which includes the RAI1 gene (90% of cases), or by point mutation in the RAI1 gene (10% of cases). Laboratory diagnosis is through cytogenetic analysis by GTG banding and molecular cytogenetic analysis by FISH. We carried out an active search for patients in Associations of Parents and Friends of Exceptional Children (APAE) of São Paulo and genetic centers in Brazil. Forty-eight patients were screened for mental retardation, craniofacial abnormalities and stereotyped behavior with a diagnosis of SMS. In seven of them, chromosome banding at high resolution demonstrated chromosome 17p11.2 deletions, confirmed by FISH. We also made a meta-analysis of 165 cases reported between 1982 and 2010 to compare with the clinical data of our sample. We demonstrated differences between the frequencies of clinical signs among the cases reported and seven Brazilian cases of this study, such as dental anomalies, strabismus, ear infections, deep hoarse voice, hearing loss, and cardiac defects. Although the gold standard for diagnosis of SMS is FISH, we found that the GTG banding technique developed to evaluate chromosome 17 can be used for the SMS diagnosis in areas where the FISH technique is not available.

    The ability to integrate theory with practice is integral to a student's success. A common reason for attrition from a nurse anesthesia program is clinical issues. To document clinical competence, students are evaluated using various tools. For use of a clinical evaluation tool as possible evidence for a student's dismissal, an important psychometric property to ensure is instrument validity. Clinical evaluation instruments of nurse anesthesia programs are not standardized among programs, which suggests a lack of instrument validity. The lack of established validity of the instruments used to evaluate students' clinical progress brings into question their ability to detect a student who is truly in jeopardy of attrition. Given this possibility, clinical instrument validity warrants research to be fair to students and improve attrition rates based on valid data. This ex post facto study evaluated a 17-item clinical instrument tool to demonstrate the need for validity of clinical evaluation tools. It also compared clinical scores with scores on the National Certification Examination.

    Road traffic accidents are known to have significant consequences for mental state and quality of life in the ensuing year that are largely unrelated to the nature of the injuries. Little is known of longer-term outcome in a representative population. Questionnaires covering mental state and social adjustment were sent to 770 subjects who had previously participated in a prospective study of consecutive attenders at an emergency department following a road traffic accident and who had completed questionnaires at baseline, 3 months and 1 year. Outcomes were not predicted by measures related to injury type or severity but were predicted by baseline and later non-injury variables. Replies were received from 507 (66%) subjects. Although 76% of injuries were medically minor bruises and lacerations, 132 (26%) reported symptoms of psychiatric disorder and 104 (21 %) moderate or severe pain at 3 years. There was little evidence of improvement in prevalence between 1 and 3 years, with continuing physical symptoms, psychiatric disorder and reported consequences for everyday life. There was a significant reduction in the number of cases of post-traumatic stress disorder (PTSD) despite there being 21 late onset cases. Psychiatric outcomes and pain were unrelated to the severity of injury and were largely predicted by post-accident variables. Road traffic accidents have much greater consequences than would be expected from the largely minor nature of the physical injuries. There is a need for changes in medical care and in socio-legal procedures.

    Purpose To determine the clinical and biologic effects of bevacizumab, an anti–vascular endothelial growth factor (VEGF) monoclonal antibody, in unresectable hepatocellular carcinoma (HCC). Patients and Methods Adults with organ-confined HCC, Eastern Cooperative Oncology Group performance status of 0 to 2, and compensated liver disease were eligible. Patients received bevacizumab 5 mg/kg (n = 12) or 10 mg/kg (n = 34) every 2 weeks until disease progression or treatment-limiting toxicity. The primary objective was to determine whether bevacizumab improved the 6-month progression-free survival (PFS) rate from 40% to 60%. Secondary end points included determining the effects of bevacizumab on arterial enhancement and on plasma cytokine levels and the capacity of patients’ plasma to support angiogenesis via an in vitro assay. Results The study included 46 patients, of whom six had objective responses (13%; 95% CI, 3% to 23%), and 65% were progression free at 6 months. Median PFS time was 6.9 months (95% CI, 6.5 to 9.1 months); overall survival rate was 53% at 1 year, 28% at 2 years, and 23% at 3 years. Grade 3 to 4 adverse events included hypertension (15%) and thrombosis (6%, including 4% with arterial thrombosis). Grade 3 or higher hemorrhage occurred in 11% of patients, including one fatal variceal bleed. Bevacizumab was associated with significant reductions in tumor enhancement by dynamic contrast-enhanced magnetic resonance imaging and reductions in circulating VEGF-A and stromal-derived factor-1 levels. Functional angiogenic activity was associated with VEGF-A levels in patient plasma. Conclusion We observed significant clinical and biologic activity for bevacizumab in nonmetastatic HCC and achieved the primary study end point. Serious bleeding complications occurred in 11% of patients. Further evaluation is warranted in carefully selected patients. PMID:18565886

    Around the year 2000, zirconia was introduced in dentistry. It is a material with great strength and attractive aesthetic properties, such as translucency and colour. Recent advances in digital dentistry are aimed at veneering the supporting structure ofzirconia with a layer of glass ceramics by means of an automated process. With the Primero process, a transparent outer layer of glass ceramic is applied directly onto the zirconia core, milled in the green stage and sintered. Because the restorations produced in this way have a two-layer structure like natural teeth, they obtain an aesthetic look similar to natural dental elements. The aim ofthis prospective study was to evaluate fit, marginal adaptation, contact with antagonists and neighbouring dental elements, aesthetics and colour. Clinical performance of Primero restorations were evaluated over a period of6 months and the results were compared with a previous study of CAD/CAM copings which were produced with the same method, but were veneered by hand in the traditional way.

    This clinical study evaluated the behavior of inlay fixed partial dentures (IFPD) with conventional and modified framework designs over a period of 12 to 48 months. Forty-one glass fiber-reinforced composite IFPDs were made to replace one missing maxillary or mandibular tooth. The frameworks were made only with parallel fibers in 19 restorations (group 1) and built with parallel and woven fibers modifying the design of the pontic element in 22 IFPDs (group 2) according to the manufacturer's instructions. All restorations were evaluated by color match, marginal discoloration, secondary caries, surface texture, marginal adaptation, fracture, and postoperative sensitivity. Three partial adhesive-cohesive veneering composite fractures occurred in the pontic element in group 1 after 3, 4, and 8 months, respectively. One cohesive fracture occurred in an abutment in group 2 after 46 months. Group 1 showed a 16% fracture failure rate; group 2 showed a 5% failure rate. However, no statistical difference was detected between the groups. IFPDs received the highest score at the following rates: color match 71%, marginal discoloration 96%, secondary caries 99%, surface texture 88%, marginal adaptation 98%, fracture 90%, and postoperative sensitivity 100%. Statistical analysis indicated significant deterioration of color match from baseline to last recall. There were nonsignificantly fewer fractures of the veneering composite with the modified design of the framework than with the conventional design. Repair of the fractured veneer of IFPDs may lengthen the lifespan of the restorations, but it is advisable only for slight damage.

    Respiratory rate has been shown to be an important predictor of cardiac arrest, respiratory adverse events and intensive care unit admission and has been designated a vital sign. However it is often inadequately monitored in hospitals. We test the hypothesis that RespiraSense, a piezoelectric-based novel respiratory rate (RR) monitor which measures the differential motion of the chest and abdomen during respiratory effort, is not inferior to commonly used methods of respiratory rate measurement. Respiratory rate was compared between the developed RespiraSense device and both electrocardiogram and direct observation by nursing staff. Data was collected from 48 patients admitted to the post-anaesthesia care unit in a tertiary level hospital. The primary outcome measure was difference in average RR calculated over a 15 min interval between (1) RespiraSense and ECG and (2) RespiraSense and nurses' evaluation. The secondary outcome measure was the correlation between the respiratory rates measured using these three methods. The 95 % confidence interval for the difference in average RR between RespiraSense and ECG was calculated to be [-3.9, 3.1]. The 95 % confidence interval for the difference in average RR between RespiraSense and nurses' evaluation was [-5.5, 4.3]. We demonstrate a clinically relevant agreement between RR monitored by the RespiraSense device with both ECG-derived and manually observed RR in 48 post-surgical patients in a PACU environment.

    Compared with the recent rapid advances in the diagnosis of tuberculosis, advances in the treatment of tuberculosis have been quite slow. For example, as long as six months are required for initial treatment, even with addition of pyrazinamide in the first two months to isoniazid, rifampicin, and streptomycin or ethambutol. Moreover, it is not always easy to treat patients who cannot receive standard agents including isoniazid and rifampicin due to adverse effects of these drugs or drug resistance. For these reasons, the development of new agents with potent antituberculosis activities and fewer adverse effects is urgently desired. However, at present, few new antituberculosis agents are being developed, and new quinolones are considered the most promising new antituberculosis agents due to their lack of cross-resistance to previously existing antituberculosis agents, their excellent in vitro and in vivo antituberculous activities, and good pharmacokinetics. We therefore reviewed experimental studies and clinical reports useful for evaluation of potential clinical use of new quinolones as antituberculosis drugs. Our conclusions are summarized below: 1) Of nine new quinolones on the market, ofloxacin, ciprofloxacin, aparfloxacin and levofloxacin have excellent in vitro and in vivo antituberculous activities without cross-resistance to previously existing antituberculosis agents. 2) Ofloxacin appears to be useful clinically for intractable multidrug-resistant tuberculosis. The incidence and severity of adverse effects of ofloxacin were very low on longterm administration. 3) Ofloxacin resistance emerged from two to four months after initiation of administration of ofloxacin, and ofloxacin exhibited cross-resistance to other new quinolones. 4) The usefulness of new quinolones for initial treatment of tuberculosis is unclear. 5) New quinolones should be used to treat patients with drug-resistant tuberculosis and those patients for whom adverse effects have limited the

    The development of new high strength ceramic abutments can enhance the overall aesthetic outcome of an implant-supported prosthesis. This study was to compare the clinical application of alumina and zirconia ceramic implant abutments in the anterior region. Twenty-three consecutive patients requiring single-tooth implants in the anterior region were randomized to receive either an alumina ceramic abutment (CeraAdapt) or a zirconia ceramic abutment. All-ceramic (IPS-Empress 2) crowns were then fabricated and cemented over the abutments with composite cement. Peri-implant mucosal health and bone levels were evaluated by the gingival index and radiographs at 2-week and 1-year follow-up. Aesthetic outcomes as well as technical problems with the restorations were evaluated during the observation period from 12 to 48 months after functional loading. A total of 17 alumina ceramic abutments and 18 zirconia ceramic abutments were evaluated. No patients dropped out during the study period. Eighteen out of the 23 patients maintained good function throughout the study. The median observation period was 21 months. Ceramic crown loosening was found in two restorations at 1-week and 2-years respectively after insertion. One ceramic crown fractured at 1 week after insertion. At 1-year follow-up, mean marginal bone loss around implants was 1.2 +/- 0.5 mm and the peri-implant mucosa in relation to abutment or crown was healthy with a mean gingival score of 0.6 +/- 0.2. All patients were satisfied with the final aesthetic outcome. However, two alumina abutments fractured after two years of loading. In conclusion, both ceramic abutments have shown a favourable biological response and aesthetic outcome; however, zirconia abutments with their superior mechanical properties might be better for supporting single-tooth implant restorations in the aesthetic zone.

    SUMMARY Objective The aim of this prospective pilot clinical case series report was to evaluate, through a clinical and radiographic analysis, the peri-implant bone resorption of the tantalum dental implants (TMT) (Zimmer TMT, Parsippany, NJ, USA) one year after prosthetic rehabilitation. Methods Twenty tantalum dental implants were placed in both maxillas and mandibles of 20 patients. Patients were asked to attend a radiographic and clinical follow-up and their previous clinical records and X-rays were assessed. Bone levels were calculated by digitally measuring the distance from the implant shoulder to the first bone-to-implant on periapical radiographs taken at surgery and after 6 and 12 months of functioning. The Pearson correlation analysis was performed to assess it there was a correlation between the measurement of the marginal bone loss (MBL). The Anova Test with a post-hoc analysis using Bonferroni’s test was used to compare the three group (0, 6 months and 12 months). Results The mean total MBL for the group 0 months was 0.84 mm (SD 0.21), 6 months was 0.87 mm (SD 0.22) and for 12 months was 0.89 mm (SD 0.23). The values of the Pearson’s coefficients showed that the data measurement were positively correlated. The Anova test showed a statistically significant difference between the groups. Conclusion The statistically significant difference in marginal bone loss can be considered physiological. Within the limits of this study it can be concluded that TMT implants have an excellent bone crest’s stability, however, to have most accurate information, will be necessary extend the sample.

    Electronic clinical tracking systems are used in many educational institutions of higher learning to document advanced practice registered nursing students' clinical experiences. Students' clinical experiences are constructed according to the National Organization of Nurse Practitioner Faculties core competencies. These competencies form a basis for evaluation of advanced practice registered nursing programs. However, no previous studies have evaluated the use of electronic clinical tracking systems to validate students' clinical experiences in meeting national core competencies. Medatrax, an electronic clinical tracking system, is evaluated using a formative program evaluation approach to determine if students' clinical documentations meet Family/Across the Lifespan Nurse Practitioner Competencies in a midsouthern family nurse practitioner program. This formative program evaluation supports the use of an electronic clinical tracking system in facilitating accreditation and program outcome goals. The significance of this study is that it provides novel evidence to support the use of an electronic clinical tracking system to assist a midsouthern school of nursing in meeting national core competencies.

    The oral ingestion of elemental mercury is unlikely to cause systemic toxicity, as it is poorly absorbed through the gastrointestinal system. However, abnormal gastrointestinal function or anatomy may allow elemental mercury into the bloodstream and the peritoneal space. Systemic effects of massive oral intake of mercury have rarely been reported. In this paper, we are presenting the highest single oral intake of elemental mercury by a child aged 3 years. A Libyan boy aged 3 years ingested approximately 750 grams of elemental mercury and was still asymptomatic. The patient had no existing disease or abnormal gastrointestinal function or anatomy. The physical examination was normal. His serum mercury level was 91 µg/L (normal: <5 µg/L), and he showed no clinical manifestations. Exposure to mercury in children through different circumstances remains a likely occurrence.

    Two studies examined the influence of similarity on 3-year-old children's initial liking of their peers. Children were presented with pairs of childlike puppets who were either similar or dissimilar to them on a specified dimension and then were asked to choose one of the puppets to play with as a measure of liking. Children selected the puppet whose food preferences or physical appearance matched their own. Unpacking the physical appearance finding revealed that the stable similarity of hair color may influence liking more strongly than the transient similarity of shirt color. A second study showed that children also prefer to play with a peer who shares their toy preferences, yet importantly, show no bias toward a peer who is similar on an arbitrary dimension. The findings provide insight into the earliest development of peer relations in young children. Copyright (c) 2009 Elsevier Inc. All rights reserved.

    Two studies investigated the influence of external rewards and social praise in young children's fairness-related behavior. The motivation of ninety-six 3-year-olds' to equalize unfair resource allocations was measured in three scenarios (collaboration, windfall, and dictator game) following three different treatments (material reward, verbal praise, and neutral response). In all scenarios, children's willingness to engage in costly sharing was negatively influenced when they had received a reward for equal sharing during treatment than when they had received praise or no reward. The negative effect of material rewards was not due to subjects responding in kind to their partner's termination of rewards. These results provide new evidence for the intrinsic motivation of prosociality-in this case, costly sharing behavior-in preschool children.

    Radio observations of gamma-ray burst (GRB) afterglows are essential for our understanding of the physics of relativistic blast waves, as they enable us to follow the evolution of GRB explosions much longer than the afterglows in any other wave band. We have performed a 3-year monitoring campaign of GRB 030329 with the Westerbork Synthesis Radio Telescopes and the Giant Metrewave Radio Telescope. Our observations, combined with observations at other wavelengths, have allowed us to determine the GRB blast wave physical parameters, such as the total burst energy and the ambient medium density, as well as to investigate the jet nature of the relativistic outflow. Further, by modelling the late-time radio light curve of GRB 030329, we predict that the Low-Frequency Array (30-240 MHz) will be able to observe afterglows of similar GRBs, and constrain the physics of the blast wave during its non-relativistic phase.

    The International Space Station (ISS) Environmental Control and Life Support System (ECLSS) is designed to be maintainable. During the 3 years since the ISS US Lab became operational, there have been numerous ECLSS Orbital Replacement Units (ORUs) launched and returned to Maintain the ECLSS operation in the US segments. The maintenance logistics have provided tools for maintenance, replaced limited life ORUs and failed ORUs, upgraded ECLSS hardware to improve reliability and placed critical spares onboard prior to need. In most cases, the removed ORUs have been returned for either failure analysis and repair or refurbishment. This paper describes the ECLSS manifesting history and maintenance events and quantifies the numbers of ECLSS items, weights, and volumes.

    Based on its 20 years experience in manufacturing semiconductor devices, Atmel Nantes has chosen to apply QML concept to move from Product Qualification to Technology Qualification. Defense Supply Center Colombus granted Atmel Nantes QML Q & V (class Q = military quality level , class V = space quality level), in December 1999. A demonstration phase is on-going with draft ESA/SCC 25400 and 2549000 basic specifications for the definition of a European QML. Atmel is a candidate as an integrated microcircuits manufacturer. After 3 years producing QML devices, some optimisations of screening tests have been implemented. This appears to be a valid solution for reducing both cost and cycle time with no impact on product reliability.

    Patients with sequelae from multiple trauma commonly display cognitive disturbances, specifically in the areas of attention and memory. This study was designed to assess cognitive functioning 3 years after severe multiple trauma and to investigate how cognitive performance is related to head injury severity and psychological distress respectively. Sixty-eight multiple trauma patients were tested with a screening battery consisting of six neuropsychological tasks 3 years after injury. A measure of psychological distress (20-item General Health Questionnaire, or GHQ-20) was also administered. Patients who neither showed signs of reduced consciousness on admission to the hospital nor reported significant psychological distress at follow-up tended to have normal test performance. In five of the six tasks, cognitive impairment was related to the severity of the traumatic brain injury as measured by the Glasgow Coma Scale (GCS). In both attention span tasks, patients designated as cases by the GHQ had significantly lower scores than noncase patients. These bivariate relationships were upheld in multiple regression analyses, in which age, sex, and GCS and GHQ scores were entered as independent variables. When patients with severe head injuries were excluded from the analyses, GCS scores still contributed to the variance in tests of verbal attention span and delayed recall, but performance on attentional tasks was more strongly related to psychological distress than to GCS scores. Cognitive deficits in multiple trauma patients were related both to the severity of the traumatic brain injury and to the degree of psychological distress. The strength of the association between brain injury as indicated by GCS scores and cognitive performance differed between different tasks. Neuropsychological testing may assist in differentiating primary organic from secondary psychogenic impairments.

    To explore change in activity levels post-stroke. We measured activity levels using the activPAL™ in hospital and at 1, 2 and 3 years' post-stroke onset. Of the 74 participants (mean age 76 (SD 11), 39 men), 61 were assessed in hospital: 94% of time was spent in sitting/lying, 4% standing and 2% walking. Activity levels improved over time (complete cases n = 15); time spent sitting/lying decreased (p = 0.001); time spent standing, walking and number of steps increased (p = 0.001, p = 0.028 and p = 0.03, respectively). At year 3, 18% of time was spent in standing and 9% walking. Time spent upright correlated significantly with Barthel (r = 0.69 on admission, r = 0.68 on discharge, both p < 0.01) and functional ambulation category scores (r = 0.55 on admission, 0.63 on discharge, both p < 0.05); correlations remained significant at all assessment points. Depression (in hospital), left hemisphere infarction (Years 1-2), visual neglect (Year 2), poor mobility and balance (Years 1-3) correlated with poorer activity levels. People with stroke were inactive for the majority of time. Time spent upright improved significantly by 1 year post-stroke; improvements slowed down thereafter. Poor activity levels correlated with physical and psychological measures. Larger studies are indicated to identify predictors of activity levels. Implications for Rehabilitation Activity levels (measured using activPAL™ activity monitor), increased significantly by 1 year post-stroke but improvements slowed down at 2 and 3 years. People with stroke were inactive for the majority of their day in hospital and in the community. Poor activity levels correlated with physical and psychological measures. Larger studies are indicated to identify the most important predictors of activity levels.

    This case report describes an esthetic treatment to improve the shape and alignment of the anterior teeth, reestablishing smile harmony, using feldspathic porcelain veneers. Results of clinical follow up after 36 months are also presented. The advantages, disadvantages and limitations of the technique are detailed with reference to the relevant literature. This suggests that the success of treatment depends on adequate conditions of bonding between the veneers and the tooth complex, which involves parameters such as the strength and durability of the bond interface. Therefore, the clinical success of feldspathic porcelain veneers depends on the accurate selection of cases and correct execution of clinical and laboratory procedures. The rehabilitation involved from first right premolar to the left with feldspathic porcelain veneers made on refractory dies. After the 3-year follow up, excellent clinical results and patient satisfaction were achieved.
