RESUMO
AIM:To evaluate the relationship between dry eye disease(DED)and physical and mental health in teachers, and to explore its mechanism and propose intervention measures.METHODS:Cross-sectional study. A total of 183 teachers from three primary and secondary schools in the urban area of Linyi City, Shandong Province were enrolled in the study. DED symptoms were quantified using the ocular surface disease index(OSDI)questionnaire. A compact version of the depression, anxiety, and stress scale(DASS-21)was used to evaluate psychological state. The relationship between potential influencing factors and DED was evaluated by independent sample t-test of quantitative variables and χ2test of classified variables. Logistic regression analysis was used for multivariate analysis to determine the influencing factors of DED. Pearson correlation coefficient was used to analyze the correlation between OSDI score and depression, anxiety and stress.RESULTS: There were 183 teachers, including 44 males(24.0%)and 139 females(76.0%), aged from 22 to 57 years, with an average age of(34.2±8.6)years. The prevalence of DED was 60.0%(109/183; 95%CI 52.4%-66.7%). The prevalence of depression was 26.2%(48/183; 95%CI 19.8%-32.7%); anxiety prevalence was 39.3%(72/183; 95%CI 32.2%-46.5%); and stress prevalence was 23.0%(42/183; 95%CI 16.8%-29.1%). The univariate analysis showed that increased age, increased working years, increased visual display terminal(VDT)application time, longer written working hours, reduced sleep hours, less alcohol consumption, and high scores of depression, anxiety and stress were all factors affecting DED(all P<0.05). Using depression scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours, sleep time, alcohol consumption and depression score were the influencing factors of DED(all P<0.05); Using anxiety scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours and stress scores were the influencing factors of DED(all P<0.05); Using stress scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours and stress scores were the influencing factors of DED(all P<0.05). OSDI scores were positively correlated with depression, anxiety, and stress scores in the DED group(P<0.05)and across all participants(P<0.05). In the severe DED group, OSDI scores were positively related to depression, anxiety, and stress scores(P<0.05).CONCLUSION: The prevalence of DED is high among the teachers. Alcohol consumption, reduced sleep, longer working years, longer VDT usage and longer written working hours are the influencing factors of DED. In severe DED group, DED is highly correlated with depression, anxiety, and stress. We should pay attention to teachers' DED and related physical and mental health problems, and actively prevent and make early diagnosis and treatment.
RESUMO
Objective@#To investigate the early diagnosis and treatment for burn complicated with severe paroxysmal sympathetic hyperactivity (PSH).@*Methods@#Medical records of patients with burn complicated with severe PSH, admitted to our department from April 2016 to March 2019 and meeting the inclusion criteria were analyzed retrospectively. There were 4 males and 1 female, aged 17 months to 39 years, with an average of (21±16) years. During occurrence of PSH, the vital signs of patients were routinely monitored and oxygen were given. Other treatment included central venous catheterization and infusion of electrolyte solution, infusion of plasma according to patients′ condition, use of opioid analgesics and benzodiazepine sedatives, physical cooling and drug cooling, and establishment or maintenance of artificial airway and use of ventilator. Heart rate was controlled below 120 beats per minute in adults and 140 beats per minute in children with comprehensive treatment dominated by analgesia and sedation. Besides, single or multiple vasoactive agents, even in large doses were used to maintain normal blood pressure of patients. The occurrence characteristics, time, and treatment outcome of PSH were analyzed.@*Results@#PSH happened rapidly, with a sharp increase in several minutes to dozens of minutes. Five patients were with symptoms such as high body temperature, shortness of breath, very fast heart rate, normal or elevated systolic blood pressure, hyperhidrosis, and dystonia at the onset. The symptoms occurred simultaneously or successively. According to the Clinical Feature Scale, the above-mentioned 6 indexes achieved the highest score of 3 points except of systolic blood pressure. Four patients showed dilated pupils and impaired consciousness. Among the patients, PSH occurred in the acute exudation stage in 3 patients, in the fluid reabsorption stage in 1 patient, and in the late repair stage in 1 patient. PSH of patients lasted for 3 hours to 12 days. The symptoms of 4 patients were effectively controlled, and 1 patient died of deterioration. No PSH occurred in the cured patients during follow-up of 3 to 14 months.@*Conclusions@#Burn complicated with PSH can occur at any time before wound repair and in patients with different injury conditions. The causes of PSH include sudden burn, persistent pain, fright and fear, strange environment, low blood volume, and other adverse stimuli, and PSH is more likely to occur in children with underdeveloped brain function. Intravenous infusion of analgesics sedatives, physical therapy and medication to lower body temperature, stabilizing blood pressure and respiration are effective measures to treat PSH. PSH should be distinguished from the common complications of burns, such as sepsis, cerebral edema, hyperpyretic convulsion, transfusion response, stress disorder, etc.
