Metabolic Associations with Skin Tags
No full textBackground: Skin tags are small, soft, pedunculated, often pigmented lesions, usually occurring on the eyelids, neck and axillae. There have been a few reports in the literature that the presence of skin tag is associated with different components of the metabolic syndrome.
Objective: To evaluate the relationship between components of metabolic syndrome (atherogenic lipid, glucose level, hypertension, and waist circumference) and other metabolic associations with skin tag
Metabolic Associations with Skin Tags
No full textBackground: Skin tags are small, soft, pedunculated, often pigmented lesions, usually occurring on the eyelids, neck and axillae. There have been a few reports in the literature that the presence of skin tag is associated with different components of the metabolic syndrome.Objective: To evaluate the relationship between components of metabolic syndrome (atherogenic lipid, glucose level, hypertension, and waist circumference) and other metabolic associations with skin tags.Patients and Methods: A total of 51 patients with skin tags aged 16 to 64 years, 13 males (31.37%), 38 females (68.63%) with a mean age of (38.6 ± 12.1 SD); and 50 healthy controls aged 19 to 60 years, 13 males (30%) and 37 females (70%) with a mean age of (37.9 ± 9.4 SD) were examined in dermatology outpatient clinic of Kufa Medical School Teaching Hospital, Najaf, Iraq. Body Mass Index (BMI),waist circumference (WC),blood pressure (BP), fasting blood sugar (FBS), serum lipids including triglyceride, total cholesterol, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), liver enzymes (AST, ALT), alkaline phosphatase and serum uric acid were measured for both study groups. The study was approved by Ethics Committee of Kufa Medical School in Iraq.Results: There was no significant statistical difference in fasting blood sugar, serum uric acid, liver function tests, triglyceride, high density lipoprotein and very low density lipoprotein between the study groups. Patients group has showed significantly higher levels of total cholesterol and LDL, when compared with the healthy controls group (P < 0.01). Also patients group showed significantly higher values of BMI, blood pressure (BP), and Waist circumference (WC) compared with the healthy controls group (p = 0.0001), ( p = 0.001) and (P < 0.01) respectively. It has been found that 37 (72.5%) of the patients and 13 (26%) of the controls meet at least three of the criteria of metabolic syndrome.Conclusion: Total cholesterol and LDL serum levels should be checked in patients with skin tags. On the other hand, glucose, serum levels may not be as important as what is being considered in recent time.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Treatment of Molluscum Contagiosum by Potassium Hydroxide Solution 20% with and Without Pricking and By Pricking Alone: A Comparative Study with Review of Literature
No full textBackground: Molluscum Contagiosum is a common viral skin infection, caused by poxvirus, commonly affects young children. Although there is no specific treatment for this infection, many therapeutic modalities has been used with different success rates.Objectives: To evaluate the effectiveness of topical 20% KOH, 20% KOH with pricking and pricking alone as comparative treatments for molluscum contagiosum.Patients and methods: This study was conducted in the Dermatology Clinic of Kufa Medical School Teaching Hospital in Iraq, from August 2011 to January 2013. Ninety patients with Molluscum Contagiosum were recruited. Diagnosis of Molluscum Contagiosum was confirmed on clinical bases.Patients with prior treatment for the last month and patients who had inflamed lesions were excluded. Full history and physical examination were done for all Patients. The patients were divided into three groups: Group 1included 30 patients treated with topical KOH 20% applied by wooden stick daily at bed time. Group 2 included 30 patients treated by pricking the lesions by 27 G needle wet in 20% KOH weekly. Group 3 included 30 patients treated by pricking alone once weekly.Treatment sessions were continued until complete cure or maximum of four sessions was achieved. The patients were followed up for two months period from the last session.Results: Out of the ninety patients, 57 completed the study. There were thirty one (54.3%) males and 26 (45.6%) females with male to female ratio 1.19-. Their ages ranged from 1.5-62 years (mean and standard deviation of 19.4±16.7). The most common age group affected was below 12 years, 29 (50.8%) patients. The most commonly affected body sites were the face and neck, 49 (85.9%) patients. After 4 sessions, the response rate was as follows:- Group 1, 17 (94.4%): patients were cured completely and relapse was not recorded; p-value was highly significant (=0.0019).- Group 2, 20 (86.4%) patients were completely cured and relapse was not recorded; p-value was highly significant (< 0.001).- Group 3, 12 (75%) patients were completely cured and relapse was not recorded; p-value was highly significant (=0.0014).Conclusion: Pricking Molluscum Contagiosum by 27G needle alone, pricking with 20% KOH and topically applied 20% KOH all achieved comparable success rates that were all statistically significant. All three methods represented tolerable and highly effective modes of therapy.</p
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
