Bowled over by cricket: impact of tape-ball injuries on the eyes
Abstract PURPOSE:
The aim of this study was to describe the type and severity of tape-ball cricket-related eye injuries seen at a tertiary care hospital. DESIGN:
A descriptive case series. METHODS:
This study included all cases of tape-ball cricket-related eye injuries presenting to the Section of Ophthalmology, Aga Khan University Hospital, Karachi, from January 2014 to January 2015. RESULTS:
A total of 20 patients with tape-ball cricket-related eye injuries were treated during this period. The right eye was involved in most (14/20) of the cases. The commonest presenting symptoms included reduced/blurred vision, ocular pain, redness, and floaters. Sixty percent (12/20) of the affected eyes had a best corrected visual acuity of less than 20/200 at presentation, with the retina being the most commonly involved ocular structure. All patients reported that they were not wearing protective eyewear at the time of trauma. Despite standard management, half of the eyes had severe or total vision loss at the last follow-up (minimum, 3 months), mainly due to retinal damage. CONCLUSIONS:
Our study calls for the compulsory use of protective eyewear by cricket players and for countrywide surveillance data on the true burden of this unnoticed preventable cause of unilateral eye injuries and associated vision loss
To tackle symptoms of computer vision syndrome in era of COVID-19
With the emergence of a novel coronavirus, there has been an increase in the use of electronic gadgets such as laptops, tablets, and mobile phones. There has been an emphasis on social distancing and work from home. Therefore, people are switched to online mode, whether it is office work or education. Both adults and children are getting dependent on electronic devices, which has led to increased symptoms of computer vision syndrome (CVS). Here, we address the symptoms that can occur with enhanced use of digital media and how that could be tackled
A 10-year review of indications for penetrating keratoplasty in a tertiary care setting in Karachi Pakistan
Abstract
The retrospective study was conducted to determine the indications and outomes of penetrating keratoplasty(PKP) in a tertiary caresetting in Pakistan. All eyes that had undergone PKP between January 2005 and December 2014 at the Aga Khan University Hospital, Karachi, were included.Data were collected on the indications of PKP, graft survival (graft clarity at final follow-up), andbest corrected visual acuity (BCVA).Kaplan-Meier\\u27s method was usedto analyse graft survival.Out of 437 eyes, 383(87%) were for visual purpose. Trauma-related corneal scarring 113(26.2%) was the leading cause of PKP, followed by keratoconus 74(17.1%), redo graft 56(13%), infection-related corneal opacity 46(10.6%), corneal dystrophy 44(10.2%) and bullous keratopathy 36(8.3%). The probability of graft survival at 30 months was 90% for keratoconusversus 75% for the non-keratoconus grafts. Most of the PKPs in this case series were due to preventable causes. Our long-term PKP results were favourable, with a graft survival ratecomparable to those of other centres
4.60 EVOLUTION OF CHILD AND ADOLESCENT PSYCHIATRY: A BIBLIOMETRIC ANALYSIS OF THE TOP SEVEN JOURNALS OF CHILD AND ADOLESCENT PSYCHIATRY
Child psychiatry: A scientometric analysis 1980-2016.
Background: The field of child and adolescent psychiatry lags behind adult psychiatry significantly. In recent years, it has witnessed a significant increase in the publication of journals and articles. This study provides a detailed bibliometric analysis of articles published from 1980 to 2016, in the top seven journals of child and adolescent psychiatry. Methods: Using the Web of Science core collection, we selected 9,719 research papers published in seven psychiatric journals from 1980 to 2016. We utilized the Web of Science Analytics tool and Network Analysis Interface for Literature Studies (NAILS) Project scripts to delineate the general trends of publication in these journals. Then, co-citation analysis and hierarchical cluster analysis was performed using CiteSpace to map important papers, landmark theories and foci of research in child and adolescent psychiatry. Results: The field of child and adolescent psychiatry has experienced an increasing trend in research, which was reflected in the results of this study. Hierarchical cluster analysis revealed that the research foci in psychiatry were primarily studies related to the design of psychometric instruments, checklists, taxonomy, attention deficit hyperactivity disorder (ADHD), depression, PTSD, social phobia, and psychopharmacology. Moreover, several landmark studies, including the validation of a child behavior checklist, Ainsworth's empirical evidence of Bowlby's attachment theory, and adult outcomes of childhood dysregulation were published. This study also reports rapid expansion and innovation in research areas in the field of child and adolescent psychiatry from 1980-2016. Conclusions: Rapid expansion and innovation in research areas in the field of child and adolescent psychiatry has been observed, from 1980 to 2016
Bibliometrics of the 100 most-cited articles on refugee populations
Background: Bibliometrics is a form of quantitative analysis that employs peer-reviewed research, journal articles and citation counts to examine the content of current literature on a particular topic. The authors aim to identify the major academic disciplines that dominate the landscape of published materials and research endeavors on the topic of refugees. Methods: : Using the Web of Science, a database of most-cited articles was created by a team with expertise in bibliometrics. Results: : Citations ranged between 1,493 and 105; averaging 203 citations per article. The publications spanned the years from 1973 to 2010. The year 2004 had the highest number of publications. All articles were published by 45 journals. In total, 294 investigators authored these articles. Psychiatry, psychology and public health constituted the top three fields of affiliation, with the most investigated feature being the mental health of refugees. Single investigators authored a quarter of all articles. Conclusion: This bibliometric evaluation allowed a multi-dimensional outlook on the conditions of refugee populations across the globe, through collation of relevant peer-reviewed research journal articles. This specialized form of assessment has resulted in a multi-disciplinary compendium of publications on the subject
Saving Energy in the Transportation Sector: An Analysis of Modified Bitumen Application Based on Marshall Test
Energy consumption and material production are two major factors associated with the road construction industry. Worldwide, millions of tons of hot mix asphalt production consume a huge amount of fuel as an energy source in terms of quantity and cost to achieve the standard temperature of up to 170 °C during the mixing process. Modification of bitumen can not only reduce its usage but also the consumption of energy (fuel) during the asphalt mix production process at low temperatures. This study provides a method to save energy by proposing the addition of bitumen modifier in the road construction sector. Furthermore, to make it compatible with the field conditions for road construction, stability analysis is executed on the prepared samples by partially replacing the bitumen with polyurethane foam (PUF) and plastic waste (PW) (at 10%, 20%, 30%, 40%, and 50%). Experimental results demonstrate a reasonable saving in the amount of energy (33%) and material (40% bitumen) used and showed that similar strength of developed asphalt mix can be achieved using PUF. An extensive calculation concludes that these savings could make a huge difference in construction economics of mega road infrastructure projects, especially during an energy crisis
