    Background: So far, the thresholds for the presence of leg oedema are not well standardized. The terms leg swelling and lymphoedema are often used as synonyms. Methods: In this prospective study, we analyzed various aspects of leg swellings: a) the subjectively perceived swelling, b) the clinically detected swelling and c) exact leg volume differences, measured by the Image 3D method. We included 164 study participants (31 control persons, 25 patients with chronic venous insufficiency (CVO, 74 patients with sentinel lymphonodectomy (SLNE), and 34 patients with complete inguinal lymph node dissection (CLND). Applying Receiver Operating Characteristic analysis, a volumetric threshold for the perceived leg swelling was established. Results: Of the persons included, 67 (41%) reported subjectively perceived leg swellings. The proportions in control persons, in patients with CVI, with SLNE and with CLND were 23%, 48%, 31 % and 74%, respectively. The percentages of clinically detectable swelling were 3 A), 13%, 15% and 50%, respectively. Applying a threshold of 6.5 % volume gain of the operated leg, the lymphoedema rates after SLNE and CLND were 7% and 35%, respectively. Among the patients with lymph node dissection, we built three groups. 1) patients without perceived swelling or clinical signs of swelling, 2) patients with perceived swelling but no clinical signs of swelling and 3) patients with perceived swelling as well as clinical signs of swelling. In these groups, the mean volume differences between the operated and the non-operated leg were 71 ml (0.9%), 150 ml (2.2 %) and 477 ml (5.9%), respectively (P<0.001). A threshold of 2.4% volume gain of the operated leg provided the best conformity with the perceived swelling. Conclusions: The perception of swelling can be caused by small amounts of liquid accumulation in the leg and may be present although clinical signs are still missing. Consequently, the highest swelling rates are recorded if a questionnaire is used. Significantly lower swelling rates are found by clinical examination. The lowest swelling rates are observed, if a volumetric threshold of 6.5% volume gain is applied

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Ophthalmology. 2005 Feb;112(2):208-18; discussion 219. Mitomycin C modulation of corneal wound healing after photorefractive keratectomy in highly myopic eyes. Gambato C, Ghirlando A, Moretto E, Busato F, Midena E. SourceRefractive Surgery Service and Antimetabolite Therapy Research Unit, Department of Ophthalmology, University of Padova, Padova, Italy. Abstract PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes. DESIGN: Prospective, double-masked, randomized clinical trial. PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia. METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months). MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH. RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively). CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK. Comment in Ophthalmology. 2006 Feb;113(2):357; author reply 357-8

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    Pulsatile subcutaneous versus bolus intramuscolar gonadotropin administration after pituitary suppression with a long-acting GnRH analogue: a controlled prospective study.

    The potential advantages of pulsatile s.c. administration instead of daily bolus i.m.administration of human urinary gonadotrophin preparations were tested after the administration of a long-acting gonadotrophin-releasing hormone (GnRH) analogue within a programme for in-vitro fertilization (IVF) and embryo transfer. First, the pharmacokinetic properties of human urinary gonadotrophins were analysed with immunological and biological methods, both during bolus i.m. injections and during pulsatile s.c. administration. Second, a prospective randomized controlled study was performed in 75 patients undergoing IVF/embryo transfer in whom the effects of pulsatile s.c. administration were compared with the effects of single daily bolus i.m. injections of the same gonadotrophin preparation. The results showed that neither method of gonadotrophin administration induced measurable changes in the serum concentration of luteinizing hormone (LH). Both oestradiol and andro-stenedione concentrations were slightly lower during pulsatile s.c. gonadotrophin administration, suggesting that this method of gonadotrophin administration results in less LH occupying the ovarian LH receptors. Pulsatile s.c. gonadotrophin administration resembles a continuous infusion of follicle-stimulating hormone (FSH). Significant fluctuations in the serum concentrations of FSH were observed during single daily bolus i.m. administration of human urinary gonadotrophins, but the pregnancy rate of IVF/embryo transfer per cycle after pulsatile s.c. administration was not significantly better than after the daily bolus i.m. injection of gonadotrophins (42.1 versus 37.2%). It is concluded that pulsatile s.c. administration of gonadotrophins instead of single daily injections does not improve the pregnancy rate in IVF/embryo transfe

    A Multi-Language Comparison of Influences on Author Verification using Character N-Grams

    No full text
    We create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc

    A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C

    No full text
    Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (&gt; 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.
