Current status of emergency treatment of chemical eye burns in workplaces

Chemical eye burns present an avoidable, but frequent, occupational injury with potentially detrimental consequences for the quality of life and occupational rehabilitation of the injured. A periodical review of guidelines is required to assure the optimal emergency management. We reviewed the literature with emphasis on current German guidelines, primarily MEDLINE. If the crucial first-line measure, the injury prevention has failed and an eye burn has been sustained, the immediate and copious rinsing of the eye is the pivotal emergency treatment modality. Whereas the immediacy and sufficiency of the emergency rinsing are largely unanimous, there is an ongoing debate about the benefits and risks of specific rinsing solutions, and regular updates on guidelines and recommendations for the emergency treatment are warranted. The easiest and readily available rinsing solution is tap water, which fulfils the crucial criteria conveniently in most industrialized countries: purity, sterility, and neutral pH. Other rinsing solutions are proposing higher osmolality to stabilize the physiological pH, because of their superior buffering capacity. However, there is no compelling evidence for a substantial benefit, and some reports suggest that there could be unwanted side effects. In combination with the substantially increased expenditure and a more complex handling procedure, currently a general recommendation of any other solution than tap water is not warranted.

LETTER TO THE EDITOR: COVID-19 QUARANTINE IN OLDER PEOPLE: THE NEED TO THINK ABOUT SARCOPENIA-RELATED PHENOTYPES

The coronavirus disease 2019 (COVID-19) has rapidly become the World Health Organization’s leading priority and is imposing a wide range of public concerns (1). COVID-19 outbreak was recently declared a global pandemic that is substantially associated with hospitalization and mortality (2). Worldwide, quarantine and social distancing have been the first line measure to prevent the highly contagious virus from spreading further (3). Older age is the most important risk factor for COVID-19-related complications, with case-fatality rate ranging from 15 to 20% in octogenarians. Therefore, social distancing (and when possible isolation) has been specially emphasized in the older adults. While attempts to suppress human to human transmission are clearly warranted, prolonged home stay is expected to have adverse effects on other features of the individuals` health. For example, an abrupt reduction in physical activity patterns and increase in sedentary behaviors may lead to disuse-induced physical decline, which can be hazardous for older people who already present reduced functional reserve (4.

Non Markovian Queuing System with Restricted Admissibility Method

This article take a glance at a cluster area single server channel Queuing system, where the server gives two sorts of vacations viz., beginning one a short vacation and the long vacation is permitted as a second vacation. Long vacation is given in two stages. First stage is compulsory and if in case of need, the server goes for a optional second stage of long vacation. In addition, the concept of restricted admissibility of customers to the system is applied during the time of optional second stage of long vacation. For the above outlined covering issue, the beneficial variable method and probability approach are utilized to determine the Probability generating capacity of the line measure and the normal length of the line. In like way the other execution degrees of the model are settled utilizing Little's law. At last, the model is guarded by procedures for numerical redirection and the model is top notch by the graphical examination.
