An evaluation of 605 endoscopic examination in a rural setting, Lacor Hospital in Northern Uganda
Full text linkIntroduction: The aim of this study was to evaluate the profile of esophagogastroduodenal
(EGDS) diseases diagnosed by upper endoscopy in a rural area of Uganda in a retro-protective
study of 605 patients.
Results: The mean age of patients with digestive symptoms was 39.7yrs (SD +/-16.11) and female
gender predominated by 60% compared to the male (P value 0.000). Peasant farmers were the
commonest group with GI symptoms requiring EGDS compared to the rest 72.1% v 27.9%.
Epigastric pain was the commonest indication (58%) for EGDS, followed by chest pain (11%),
abdominal pain (8.8%), dyspahgia (7.6%) and hematemesis (7.3%). The commonest endoscopy
finding was gastritis (47.9%) followed by esophagitis (14.4%), cancer esophagus (5.1%),
esophageal varicose (4%), PUD (2.3%), gastric cancer (1%). However 19.5% of patients had
normal EGDS. There was a significant correlation between the outpatient diagnosis and
endoscopy finding (P value 0.01, r = 0.144) and between endoscopy finding and histology findings
(P value 0.001, r = 0.236). H. pylori was positive in 53% of patients with gastritis.
Conclusion: Gastritis is the commonest lesion (47.9%) of which 53% have H pylori and Cance
Case report: biloma gastrostomy after failed sonogram-guided percutaneous aspiration, pigtail catheter insertion and surgical drainage
Full text linkBilomas are rare abnormal extrabiliary accumulation of bile. This can be either
intrahepatic or extrahepatic following traumatic or spontaneous rupture of the
biliary tree. The commonest causes of biloma are surgery, percutaneous
transhepatic cholangiography, percutaneous transhepatic biliary drainage,
transcatheter arterial embolization and abdominal trauma. We report here a 15
year old patient whom we followed for over 10 years. His chief complaints were
right hypochondriac pain, loss of appetite and vomiting. Initial clinical
presentation, sonographic as well as laboratory findings suggested a liver
abscess, which was drained, but the definitive diagnosis of biloma was
entertained after sonographically guided percutaneous aspirations and
percutaneous transhepatic cholangiography 7 years later. We also discuss the
role of imaging and surgical challenges encountered that culminated into
bilomo-gastrostomy. The patient is now enjoying a peaceful life
Barriers and factors affecting personal protective equipment usage in St. Mary’s Hospital Lacor in Northern Uganda
Full text linkBackground: To protect health workers (HCWs) from risky occupation exposure, CDC developed the universal precautions (Ups) including Personal Protective Equipment (PPEs). However compliance to it by HCWs has remained poor even in high-risk clinical situation. The objective of this study was to identify and describe the factors that influence a HCWs’ decision to wear PPEs and the barriers that exist in preventing their use
Methods: A cross-sectional survey was carried out in the St. Mary’s Hospital Lacor in all the wards to collected quantitative information as well as qualitative and observational data on PPE use
Results: Out of the total 59 respondents, 2% do not know the purpose of PPE, 23.7% do not know how to don and doff PPEs, 13.6% do not use PPE even when indicated and 10% are not using an appropriate PPE. The main barriers relates to poor fitting and weak domestic gloves, few of aprons, frequent stock out and inadequate PPE as well as lack of training in PPE
Conclusion: This study provides a baseline for measuring the effectiveness of interventions to improve compliance
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
