BACKGROUND: This study researched the relationship between shift work and one of its relevant health problems, functional gastrointestinal disorders. The study targeted nurses working at a university hospital, and compared the differences in gastrointestinal disorders of shift workers and non-shift workers and identified causes that significantly influence these symptoms. METHODS: In August 2013, a self-report survey was conducted on nurses working at a university hospital. Among those sent out, 1,201 responded and 851 were used for the final analysis. RESULTS: It was shown that the frequency of gastrointestinal disorders in shift workers was 1.881 times higher than that of non-shift workers. Factors that influenced gastrointestinal disorders included age, marital status, work duration, type of employment, job satisfaction, and perceived health status. Gastrointestinal disorders were seen more often with older age, being married, longer duration of employment, non-regular worker, low job satisfaction, bad perceived health status, and shift works. CONCLUSIONS: To prevent gastrointestinal disorders in nurses who work shifts, a health checkup system should be in place for clinical nurses who are of older age and have longer employment records. To decrease the causes of gastrointestinal disorders, campaigns suggesting regular diet and quitting alcohol use should be held consistently. Also, a category related to gastrointestinal disorders should be added to the employee health checkup for nurses with long work experience.

PURPOSE: This study is performed to help manage the metabolic syndrome in work place by identifying the effect on metabolic syndrome with subjects of Korean adult workers. METHODS: Using part of data of "The Fourth Korean National Health and Nutrition Examination survey 2nd year (2008)" which center for disease control is investigating. The general characteristics include age, educational level, occupation and marital status as factors affecting the metabolic syndrome of workers in this study. RESULTS: Work-related factors are the working environment in which they are working while they are pressed for time due to work status and overload. If the work status of worker is unpaid family member, the risk is increased by more than twice compared to paid workers. The risk for metabolic syndrome in work environment to work while fighting the clock is decreased compared to the work environment without time pressure. CONCLUSION: In order to manage the metabolic syndrome of workers, health promotion program to change management of both working condition and working environment can contribute to prevent the metabolic syndrome and ultimately prevent the cerebrocardiovascular diseases.

PURPOSE: To investigate the usefulness of the serum Creatine kinase(CK), especially brain typical creatine kinase(CK-BB) as an indicator of brain damage extent, mortality and long term nurologic sequelae, the study was done. METHODS: CK and CK isoenzyme activites were measured at 6-10 hours after birth in 160 asphyxiated newborn infants who admitted in Eulji General Hospital from August 1990 to July 1994. Infants were followed up for 1 years after birth to evaluate survival and neurologic outcome. RESULTS: 1) There was low correlation between CK-BB and 5 minute Apgar score(r=0.245, p=0.0026). 2) There was intermediate correlation between CK-BB and Lactic dehydrogenase (LDH)(r=0.470, p<0.0001). 3) Infants who died within 24 hours after birth had significantly higher CK-BB activity(144.9+/-98.5U/L) than survivors(82.2+/-159U/L), (p=0.0160). Infants who died within 72 hours after birth had significantly higher CK-BB activity(130.2+/-108.4U/L) than survivors(80.5+/-161.1U/L), (p=0.0209) 4) Infants who died within 24 hours after birth had significantly higher CK-BB%(23.4+/-17.4%) than survivors(9.6+/-11.9%), (p=0.0042). Infants who died within 72 hours after birth had significantly higher CK-BB%(20.0+/-15.4%) than survivors(9.3+/-11.8%), (p= 0.0027). Infants who died within 28 days after birth had significantly higher CK-BB% (12.7+/-13.4%) than survivors(9.7+/-12.3%), (p=0.0500). 5) In the cases of neonatal seizure in 24-48 hours after birth, CK-BB was higher than in the cases of no seizure or seizure in 48 hours after birth. 6) CK-BB was well correlated to the grade of hypoxic ischemic encephalopathy. 7) CK-BB, CK-BB% and 5 minute Apgar score showed similar positive and negative predictive values for survival rate, abnormal findings of imaging studies and neurologic outcomes. CONCLUSIONS: CK-BB is a good predictive value for the death within 24 and 72 hours after birth and the neonatal seizure in 24-48 hours after birth. CK-BB% is a good predictive value of the death within 24, 72 hours and 28 days after birth. CK-BB, CK-BB% and 5 minute Apgar score showed similar predictivity for neurologic outcomes during 1 years after birth.

BACKGROUND: Cough suppression is a well-known side effect of all opioid analgesics, but we experienced cough response after small dose of intravenous fentanyl. The goal of this study was to demonstrate the tussive effect of intravenous fentanyl. Method: 311 patients (ASA class 1, 2) were assigned randomly into three groups. Patient in group 1 recieved fentanyl 1 microgram/kg, patients in group 2 were given fentanyl 2 microgram/kg, and patients in group 3 recieved fentanyl 2 microgram/kg 2 min after lidocaine 1 mg/kg. We observed for 1 min after fentanyl injection to detect a cough response. RESULTS: Tussive response of fentanyl is produced by low dose (1~2 microgram/kg) fentanyl IV, and decreased by lidocaine pretreatment. This response is decreased with aging. All event is not related bronchospasm and anticholinergic premedication. CONCLUSION: We concluded that fentanyl causes tussive response and this response is inhibited by lidocaine and decreased with aging.

Effect of diltiazem hydrochloride on cardiac performance with particular reference to the antianginal action was studied in 17 patients with ischemic heart disease, including 12 cases of effort angina, by means of clinical and mechanocardiographic evaluations. All patients were kept on the same medications from at least 2 weeks prior to diltiazem administration until the end of the study, and were prescribed no other antianginal drugs except for liberal use of sublingual nitroglycerin. Diltiazem was given 90mg a day in three divided doses for two weeks. Clinical and mechanocardiographic evaluations, including calculations of pressure rate product(PRP), triple product(TP) and tension time index(TTI), were made before and at a weekly interval after diltiazem administration. After the medication, heart rate, blood pressure and the pre-ejection period(PEP) with its ratio to the ejection time tended to decrease, and the decreases in heart rate and the PEP at the end of two weeks were significant. The PRP, TP and TTI were also significantly decreased at the end of the second week, and the decrease in the TTI was significant even a week after the medication. An antianginal effect, which appeared within few days, was excellent to good in over 90 percent of the cases. These facts suggest that diltiazem hydrochloride has no negative inotropic action and its antianginal effecti in its early stage of the drug administration is primarily due to coronary vasodilation and, as the drug is continued, is contributed to possibly by the decrease in the myocardial oxygen consumption as well.

Nerve injury associated with cardiac surgery and anesthesia is a well-recognized complication with a predilection for the upper half of the body. We report four cases of common peroneal nerve palsy following cardiac surgery that were not subject to external compression to fibular head. The diagnosis of nerve palsy was delayed because of a complicated postoperative course and intensive care, which prevented our determining the causes. The mechanisms of nerve injury are reviewed. We postulate that the etiology is multifactorial, including, old age, subnormal body habitus, prolonged knee flexion and rotation, coexisting disease, postoperative cardiovascular complications, and cardiopulmonary bypass.

PURPOSE: Diabetic children should be classified into type 1 or 2 for adequate diabetic control. However, there is a shortage of information of the appropriate criteria in Korea. This study is desinged to discover the clinical types and characteristics of diabetes mellitus(DM) in Korean children. METHODS: We studied the clinical characteristics and laboratory findings of 177 diabetic children. Classification was based on the serum C-peptide levels, presence of ketoacidosis, autoantibodies, and insulin dependence. RESULTS: Among 177 diabetic children, 147(83.1%) were classified as type 1 and 21(11.9%) as type 2, and 12(57.1%) children in type 2 were obese. All patients with age of onset before 9 were type 1. In cases of type 1, initial serum C-peptide levels were < 0.6(50%), 0.6-1.0(44%) and > 1.0ng/mL (6%). All patients with initial serum C-peptide level above 1.5ng/mL were type 2. Four patients initially diagnosed as type 2 DM changed to type 1 during follow-up, and 2 patients of type 1 DM changed to type 2. Only 55.4% of type 1 DM patients had insulin autoantibody, islet cell cytoplasmic antibody or anti-glutamic acid decarboxylase antibodies. CONCLUSION: Most diabetic children in Korea were classified as type 1. Our results suggest that insulin requiring lean patients with positive autoantibody should be classified as type 1 even if their serum C-peptide levels are within normal range, and the clinical types could be changed during follow-up in a small proportion of diabetic children.
