We carried out five common electroretinographies according to the recommendation by the International Society of Clinical Electrophysiology of Vision in the eyes of 40 non-diabetic brach retinal vein occulusion. The clear media, no previous history of photocoagulation and no evidence of neovascularization of the retina and/or iris were criteria for inclusion in this study. The data were compared with those of fellow eyes, expecting that this procedure may provide a new feature that could have some clinical significance. The reduction of the summed amplitude of oscillatory potentials, and the timing delay of the cone response b-wave and 30Hz flicker responses were of most frequent occurrence. hence, the reduction of the summed amplitude of oscillatory potentials and the timing delay of the cone response b-wave and 30Hz flicker responses may be valuable indicators. These abnormalities represent overall inner retinal dysfunction. The cone response b-wave timing was more frequently affected than that of the maximal combined response b-wave. This fact may reflect that an ischemic lesion is located in the vicinity of the posterior pole of the fundus.

This study was carried out to evaluate the relations among workers' general characteristics, work-related behaviors and health related behaviors in a steel industry with 1,134 workers in Pohang. The results were as follows; 1. The mean age of workers was 50 years old and working duration was 15 years and over. Most of them were married(94 5%) and had studied beyond high school (53.0%). They performed three shift work and most of them(63.0%) had experienced industrial accidents. The frequency of noise and dust exposure was defined by a minimum of 6 hours per day, and workers complained about noise exposure(62.9%) and dust(55.6%). There were current smokers(67.7%), current drinkers(74.3%) and current exercising workers(32.3%) in the industry. The number of cigarette consumption in current drinkers was significantly high (13.6 +/- 8.4 pieces/day) and the alcohol consumption in current smokers was significantly high(l04.5 +/- 113.5 g/wk). And the number of cigarette consumption of exercisers was significantly low and the alcohol consumption of exercisers was higher than non-exercisers. 3. The ratio of current smokers on frequent noise in exposed workers versus non-exposed workers was not significantly high but the current drinkers in frequent noise and dust exposed workers was significantly higher than non--exposed. 4. The normal levels of SGOT workers in non-smokers were significantly higher than in current smokers, and the abnormal levels of LFT(SGOT, SGPT, gamma-GTP workers in nondrinkers were significantly high. The normal levels of SBP and DBP workers in current smokers were not significantly high but were significantly high in non-drinkers. 5. The ratio of current smokers in workers unsatisfied with their job and working condition was higher than non-smokers, but the ratio of current drinkers in workers satisfied with their job and working condition were higher. 6. The significant factors for SGOT and gamma-GTP were age, the drinking amount and BMI. But the only significant factor for r-GTP was BMI. The significant factors for DBP were age, the alcohol consumption and BMI And the significant factors for SBP were age, BMI.

PURPOSE: This descriptive research study aims to investigate influential factors on human papillomavirus vaccines, among parents who have elementary school daughters. METHODS: This study was conducted with 210 parents whose children are elementary school girls, aged 9 to 12 years, in G Metropolitan City. Data were collected from August 17 to September 12, 2015 using structured questionnaires. A descriptive statistical analysis, a t-test, a χ2-test, a Fisher's exact test, and a logistic regression using SPSS/WIN 21.0. RESULTS: The influential factors on the human papillomavirus vaccination intention were confirmed to be three variables: cervical cancer knowledge, perceived sensitivity, and perceived barriers. CONCLUSION: An intervention program, both to increase the sensitivity of vaccination and to decrease barriers, should be developed so as to improve parents' health beliefs towards human papillomavirus vaccination.

BACKGROUND: It has been a standard practice in many institutions to combine light general anesthesia with epidural block for abdominal and pelvic surgery. We attempted to prove the effectiveness of prehydration and to find an suitable epidural local anesthetic dose in terms of hemodynamic stability for upper abdominal surgery. METHODS: For preliminary studies, 11 patients scheduled for elective upper abdominal surgery had received general anesthesia immediately after epidural anesthesia. After epidural injection of 10~16 mL of 2% plain lidocaine into the T9~10 intervertebral space, the changes in blood pressure were observed. Thirty-two patients scheduled for elective upper abdominal surgery were divided into two groups. In group A (study group), after prehydration with Hartmann solution (10 mL/kg), 5~7 mL of 2% plain lidocaine was injected into T8~9 or T9~10 intervertebral space and general anesthesia was then induced. Group B (control group) received general anesthesia only. RESULTS: There were no significant differences in hemodynamics between the epidural with general anesthesia and the control group except SVR (systemic vascular resistance). SVR in group A increased in contrast to the group B in which it remained unchanged. CONCLUSIONS: The combined epidural and general anesthesia, using prehydration and 0.5~1 mL/segment of 2% plain lidocaine at the T8~9 or T9~10 intervertebral space was safe without significant hemodynamic changes.

PURPOSE: Adverse health effects of smoking could be made worse by worker's tobacco use, and combining tobacco use with occupational hazards could enhance the likelihood of occupational disease and injury. This study was aimed to develop a workplace smoking cessation program based on self-determination theory (SDT) and then to examine the effectiveness of the program. METHODS: A quasi-experimental design with nonequivalent control group pretesteposttest design was used. An intervention group (n = 30) received a smoking cessation program using individual counseling and tailored text messaging based on SDT during 12 weeks. Participants in the control group (n = 30) received a smoking cessation leaflet and telephonic follow-up for 3 times. RESULTS: At 6 and 12 weeks, there were significant differences between the two groups on autonomous regulation, perceived competence, nicotine dependence, tobacco abstinence rate, and exhaled carbon monoxide concentration. At 12 weeks, the abstinence rate in the intervention group was 96.7%, whereas that in the control group was 12.9%. CONCLUSION: SDT-based workplace smoking cessation program using individual counseling and tailored text messaging is effective in encouraging autonomous regulation and competence for workers.

Essential thrombocytosis (ET) is a clonal myeloproliferative disorder, characterized predominantly by a markedly elevated platelet count without known cause. We report a case of essential thrombocytosis, the only clinical manifestation of which consisted of neurologic symptoms, including headache, dysarthria, right hemiparesis with a relatively benign and slowly progressive clinical course. Neuroradiologic examination (Brain CT and MRI) disclosed a multiple infarction in the both basal ganglia and left parietal region. These findings are discussed in relation to the possible pathogenetic mechanisms of the vascular occlusion due to abnormal platelet function in ET.

Status epilepticus is commonly defined as a condition characterized by an epileptic seizure that is so frequently repeated or so prolonged as to produce a fixed and enduring epileptic condition. Common etiologies are brain tumor, CNS infection, vascular insults, trauma, withdrawal of antiepileptic drug, and metabolic disturbance such as hypoglycemia, hypocalcemia, hyponatremia and hyperosmolarity caused by hyperglycemia, hypernatremia, and uremic encephalopathy etc. Although some cases of epilepsia partialis continua in the patient with nonketotic hyperglycemia were reported in the previous literature, we could hardly find the report that generalized convulsive status epilepticus was the initial symptom of nonketotic hypergycemia. We recently experienced three eases of nonketotic hyperglycemia who manifested generalized convulsive status epilepticus as a initial clinical feature. Two cases were completely controlled within a few hours after the correction of hyperglycemia and intravenous dilantinization. Another case was needed an additional phenobarbital administration to control the status epilepticus. In all cases, afterthen no further seizure occurred under the normal serum glucose level without use of antiepileptics.

BACKGROUND: The purpose of this study was to ascertain the prevalence of vitamin D deficiency and risk factors associated with mortality in patients > or =50-year-of-age with hip fractures. METHODS: A total of 489 patients > or =50-year-of-age who sustained a hip fracture from January 2010 to October 2014 were followed-up for a minimum of 1 year. Clinical and radiological outcomes were evaluated including prevalence of vitamin D deficiency. Crude mortality rates were calculated, and the effects of different risk factors on mortality were assessed. RESULTS: Vitamin D deficiency was present in 76.5% of cases (n=237). The prevalence of vitamin D insufficiency was 12.3%, and only 11.2% of patients had normal vitamin D levels. Accumulated mortality was 11% (54 patients) at 1 year. A univariate analysis showed that vitamin D deficiency (P=0.012), age (P<0.001), BMI (P<0.001), type of management (P<0.001), American Society of Anesthesiologists (ASA) score (P=0.009), pre-fracture ambulatory status (P<0.001), and osteoporosis (P<0.001) were associated with mortality. A multivariate analysis performed using a Cox proportional hazards model demonstrated that ASA score (P=0.001) and pre-fracture ambulatory status (P=0.011) were independently associated with mortality after hip fracture. CONCLUSIONS: We did not find a relationship between serum 25-hydroxy-vitamin D levels and mortality after hip fracture, although we observed a high prevalence of vitamin D deficiency and a significant association with mortality in the univariate analysis.
