In order to investigate symptoms prevalence related to visual display terminal (VDT) syndrome, and to evaluate the variables affecting the development of the VDT syndrome, a questionnaire survey was conducted on 119 (92 men and 27 women) VDT operators who had been engaged in one plant design company in Seoul. The results were as follows : The average age of questionnaire respondents was 30. The average years of service were 4.3 years, and the working hours per day with VDT for half of them were more than 4 hours with the average being about 4.7 hours. The majority of subjects (71 persons) were working at computer aided design (CAD) or computer programming tasks. Subjective symptoms of VDT syndrome were divided into 4 groups with musculoskeletal, eye, skin, and industrial fatigue according to their major affected organ. 4 high incidence of complaints of eye discomfort was observed. In the 3 subgroups of industrial fatigue symptom, the highest average group score was accounted for by 'dullness and sleepiness', followed by 'difficulty in concentration', 'bodily projection of fatigue' in the order of sequence, suggesting the heavier mental stress of VDT work rather than physical burden. Relationship among these 4 groups of symptoms showed statistically significant correlations one another. This result suggests that VDT syndrome is a multi-organ disease composed of these 4 symptom groups which were commonly caused by the use of VDT. Multiple regression analysis were used to examine the relationship between risk factors and these symptom groups of VDT syndrome. As the result of analysis, the most important risk factor for VDT syndrome was the average daily VDT working hours. The longer was VDT working hours, the higher was symptom prevalence of VDT syndrome. In addition, daily total working hours including VDT working hours and shift of work also affected the health of VDT users. In order to protect workers from VDT syndrome, it is urgently required to implement standard management recommendations including restriction of VDT working hours and allowance of more sufficient resting time for VDT workers.

PURPOSE: To determine the MR imaging findings of spinal cord decompression sickness. MATERIALS AND METHODS: We retrospectively analysed the spinal MR images of eight patients (M : 6, F : 2) with decompression sickness affecting the cervical spine (n=1) or thoracic spine (n=7). The observed extent, location, continuity, signal intensity and contrast enhancement pattern of spinal cord lesions were analysed. RESULTS: The chief MR finding was continuous (n=2) or non-continuous (n=3) high signal intensity on T2-weighted images in the posterior paramedian spinal cord. In three cases, additional T2 signal abnormality in the ventral horn of the gray matter was observed. There was no signal intensity abnormality on T1- weighted images or abnormal enhancement on post-Gadolinium T1-weighted images. In one case, cord swelling in addition to T2 signal abnormality was observed. CONCLUSION: MR imaging is useful for evaluating spinal cord lesions in patients with decompression sickness.

The term'ectopic pregnancy'refers to a gestation in which the fertilized ovum impl-ants on any tissue other than the mucous membrane lining the uterine cavity. The number of patients per year with an ectopic pregnancy is increasing. So we revi- ewed clinical characteristics of 503 cases of ectopic pregnancies, who were admitted and treated at the department of obstetrics and gynecology of Yeungnam University from July, 1991 to December, 1995. The results were as follows; 1. The incidence of ectopic pregnancy was 1 in 30 deliveries. 2. The most common age group was 26~30 years of age(34.5%). 3. According to obstetrical history, nullipara was 35.7% and the cases who experienced artificial abortion was 50.9%. 4. In past history, 50.9% of total cases has artificial abortion and 10.1% experienced previous ectopic pregnancy, tubal sterilization was 8.0%. 5. For chief complaints, lower abdominal pain was observed in 359 patient(71.0%), am- enorrhea in 238 patients(47.3%), and vaginal spotting in 209 patients(42.1%). 6. In oder of incidence, the site of ectopic pregnancy was fallopian tube(91.5%), cervix (1.4%) and ovary(0.8%). In tubal pregnancy, the most frequent implantation site was am- pullar portion in 373 cases(74.2%) and ruptured tubal pregnancies were 306 cases(60.8%). 7. The interval between last menstrual period(LMP) and onset of symptoms was gene- rally 6~8 weeks(36.3%). 8. 65.4% of total cases were treated by salpingectomy, 14.1% by pelviscopic operati- on, and 5.8% by salpingo-oophorectomy.

Choanal atresia is a rare congenital anomaly involving unilateral or bilateral posterior nasal choanal obstruction. Multiple associated anomalies have been described. We describe the case of a 1-month-old boy with bilateral choanal atresia, misdiagnosed after CT as a midline meningocele because the floor of the midline anterior cranial fossa was not ossified and secretion had accumulated in the obstructed posterior nasal choana.

Endogenous nitric oxide(NO) plays an important role in the regulation of blood pressure. It has been known that the evoked NO-dependent dilator system may be impaired in various hypertensive models. The effects of NG-nitro-L-arginine(L-NNA), lipopolysaccharide(LPS) and tempol on mean arterial pressure(MAP) and the effects of L-NNA on isolated aorta tone were studied in order to elucidate potential alterations in resting vasodilator tone of NO in two-kidney, one clip(2K1C) hypertension. Plasma nitrite/nitrate levels were measured by colorimetric assay, and the expression of endothelial and inducible NO synthases(eNOS, iNOS) was determined by Western blot analysis. L-NNA caused an increase of MAP, while LPS produced a hypotensive effect in both 2K1C and control rats. The magnitude of the pressor or depressor response to L-NNA and LPS was comparable in the two groups. Tempol induced a sustained decrease in MAP in 2K1C rats, while it had no effects on MAP in control rats. Plasma concentrations of NO metabolites were significantly increased following the LPS-treatment in both 2K1C and control rats, while they were not affected by tempol-treatment. In endothelium-intact aortic rings precontracted with 25 mM KCl, L-NNA caused a dose-dependent contraction. The magnitude of the maximal contraction was attenuated in 2K1C rats as compared with control. An inhibition of contractile responses to L-NNA in the hypertensive group was also shown in rubbed rings, although the magnitude of contractions was markedly reduced. The vascular expression of both eNOS and iNOS was significantly decreased in 2K1C rats as compared with control. These results indicate that 2K1C hypertension is associated with a reduced basal vasodilator tone of NO and a decrease in the vascular expression of NOS isozymes.

Mixed field agglutination is an important, but rare phenomenon of ABO blood grouping. Contrary to adults, neonatal red blood cells are immature and they present a weak ABO expression, and sometimes this result in a mixed field agglutination pattern. We report here on a case of a neonate who presented with mixed field agglutination on the ABO blood grouping during serologic testing and the neonate had a normal ABO genotype.
