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.

A study on objective personality characteristics of 41 central serous chorioretinopathy patients was performed to investigate the etiologic relationship of psychological behaviors about the central serous chorioretinopathy. Fourty-one healthy subjects were used as a control group. Authors used the Minnesota Multiphasic Personality Inventory (MMPI) which consisted of 4 validity scales and 10 clinical scales. Three neurotic scales of hypochondriasis, depression and hysteria in the atients group were significantly higher than in the normal control group even though the mean scores on each clinical scale were within normal ranges in both groups.

To obtain the basic data of prognosis of acute carbon monoxide (CO) intoxication, one hundred and sixteen cases of CO intoxication defined by carboxyhemoglobin (COHb) and admitted via emergency room of Yeungnam University Hospital from Oct. '85 to April' 89 have been clinically analyzed and evaluated, including delayed postanoxic encephalopathy (DPE) and the following results were obtained. 1. The ratio of male to female was 1:1.5 and mental state was drowsy mostly (26.2% of 116 cases) 2. The more disturbed the mental state, the more decreased was the arterial pH and PaCO₂, which may be the result of metabolic acidosis. 3. The early laboratory findings in patients of CO intoxication were as follows: leukocytosis-65.5%, increase of hematocrit-23.3%, hyperglycemia-19.8%, increase of GPT-19.8% increase of creatinine-0.9% and glucosuria-12.1%. 4. The early findings of EKG were abnormal in 35.3%: change of rhythm-25.0%, abnormal ST segment 15.5% (change of rhythm and abnormal ST segment-5.2%) but the conduction disorder was not present. 5. The abnormal EEG above mild degree was 93.1%, of which moderate was most frequent (80.2%). 6. The incidence of DPE was 7.8% among all admitted CO patients. DPE cases had long duration of exposure time (8 hours), severe leukocytosis (20,000) and an abnormal EEG (MA).

Nerve conduction studies help delineate the extent and distribution of the neural lesion. The nerve conduction was studied on upper (median, ulnar and radial nerves) and lower (personal, posterior tibial and sural nerves) extremities in 83 healthy subjects 23 to 66 years of age, and normal values were established (Table 1). The mean motor terminal latency (TL): median, 3.6 (±0.6) milliseconds; ulnar, 2.9 (±0.5) milliseconds; radial nerve, 2.3 (±0.4) milliseconds. Mean motor nerve conduction velocity (MNCV) along distal and proximal segments: median, 61.2 (±9.1) (W-E) and 57.8 (±13.2) (E-Ax) meters per second; ulnar, 63.7 (±9.1) (W-E) and 50.6 (±10.0) meters per second. Mean sensory nerve conduction velocity (SNCV): median, 34.7 (±6.7) (F-W), 63.7 (±7.1) (W-E) and 62.8 (±12.3) (E-Ax) meters per second; ulnar, 38.0 (±6.7) (F-W), 63.4 (±7.5) (W-E) and 57.0 (±10.1) (E-Ax) meters per second; radial, 45.3 (±6.8) (F-W) and 64.2 (±11.0) (W-E) meters per second; sural nerve, 43.4 (±6.1) meters per second. The amplitudes of action potential and H-reflex were also standardized. Mean H latency was 28.4 (±3.2) milliseconds. And, the fundamental principles, several factors altering the rate of nerve conduction and clinical application of nerve stimulation techniques were reviewed.

BACKGROUND: It is well known that systemic blood pressure oscillates with low(0.04~0.1Hz), mid(0.1~0.15Hz), and high(respiratory) frequency range. But there has been no study about oscillation of pulmonary artery pressure(PAP). METHOD: We measured PAP for 5 minutes in 32 patients of ventricular septal defect and stored them to computer files. Power spectral density curve was obtained. Low, mid, respiratory frequency power were measured by integrating the area within each frequency range below the power density curve. RESULT: The incidence of significant low frequency power(more than 5% of total power) were higher in patients of high PAP and hign Rp/Rs than those of low PAP and Rp/Rs(p<0.01 and p<0.005 respectively). The low frequency power positively correlates with PAP and Rp/Rs(r=0.62, p<0.0005 and r=0.61, p=0.0005 respectively). CONCLUSION: It can be said conclusively that as PAP and pulmonary vascular resistance elevates, the PAP tends to definitively oscillate in low frequency range.
