OBJECTIVES: Chronic pain is one of the most common experiences of humans and a typical psychophysiological disorder. The aim of this study was to measure the psychophysiological responses in chronic pain patients using a biofeedback system, and to compare them with the results from normal healthy subjects. METHODS: Forty two patients with chronic pain (17 males and 25 females, average age 44.67+/-11.10 years) and 42 normal healthy controls (17 males and 25 females, average age 45.17+/-10.46 years) participated in this study. Electromyography (EMG), skin conductance (SC), and skin temperature (ST) were recorded using biofeedback system during the 3 phases (baseline, stress, and recovery) of stress reactivity test, and average values of them were calculated. Difference of values between two groups in each corresponding phase was analyzed with independent t-test, and change of values across phases of stress reactivity test was analyzed with paired t-test (all two-tailed, p<0.05). RESULTS: Compared to normal controls, chronic pain patients had higher value of EMG (baseline : 8.10+/-5.97 micronV vs 4.72+/-1.52 micronV, t=-3.56, p<0.01 ; stress : 11.25+/-6.89 micronV vs 8.49+/-4.78 micronV, t=-2.13, p<0.05 ; recovery : 7.12+/-3.77 micronV vs 4.78+/-1.59 micronV, t= -3.70, p<0.01) and SC (baseline : 1.06+/-1.0 micronS vs 0.42+/-0.29 micronS, t=-4.0. p<0.01 ; stress : 1.87+/-2.05 micronS vs 1.03+/-0.86 micronS, t=-2.47, p<0.05 ; recovery : 1.74+/-1.77 micronS vs 0.64+/-0.59 micronS, t=-3.8, p<0.01) in all the 3 phases. But, skin temperature comparison did not reveal significant differences in all the 3 phases between two groups. CONCLUSION: Psychophysiological responses of chronic pain patients in stress reactivity test were different from those of normal healthy controls. These results suggest that sympathetic nervous system is more activated in chronic pain patients.

4.Combined Effects of Individual Background, Work Shift and Job Stress on the Prevalence of Sleep Problems in Hospital Employers.
Journal of the Korean Academy of Family Medicine 2003;24(3):232-244
BACGROUND: The accuracy and efficiency of a job performed by hospital employee can be linked directly with patients' health and life. It is considered that their irregular work and stress are relatively high as compared with other workplaces. In this article we tried to look into how job stress, working environment and factors of life-style influence sleep problems in hospital employees. METHODS: This research was conducted among 248 workers of a hospital in Busan on April, 2002. Sleep problems were categorized into insomnia, sleep deprivation, daytime sleepiness and snoring on the basis of the factor analysis of 11-item questions. The job stress was proposed by Karasek, etc., and measured by 14-item modified questions. The statistical analysis was conducted using Chi-square test and multiple logistic regression analysis. RESULTS: Statistically insomnia, sleep deprivation and daytime sleepiness showed a significant increase in women (OR:2.1/2.69/3.16) and shift workers (OR:4.67/3.28/1.98) and snoring showed a significant increase in obesity (OR:5.0) and smokers (OR:2.34). CONCLUSION: This research showed that many hospital employees perceive sleep disorders as critical. Especially, work shift seemed to be an important risk factor for sleep disorders.

5.Clinical Rewiew of Stomach Cancer in Young Patients.
Journal of the Korean Surgical Society 1998;54(1):56-61
Several studies have demonstrated the poor prognosis for young patients with gastric cancer. However few reports exist about the dependence of the survival rate on curative resection and cancer stage. Hospital records of 107 young gastric cancer patients who underwent operations from 1980 to 1996 were reviewed, and the results were compared with those from 3176 cases involving whole age gastric cancer patients. There were no significant differences in operation method, tumor invasion, and tumor stage between both age groups. In whole age patients, males were predominant; however in young patients, females were predominant (p=0.005). In young patients, the tumors more frequently occurred in the upper 1/3 than in whole age patients(p<0.0001). A comparison of histologic types showed that poorly differentiated histologic types, such as signet ring cells and diffuse types, according to Lauren's classification, were more frequently observed in young patients (p<0.0001). The 5- year overall survival rate revealed a difference, but with borderline significance, between the young and the whole age patients (39.4% vs 48.6%, p=0.0505). However, patients who had undergone a curative resection showed no statistically significant difference(56.9% vs 63.9%; p=0.264). And patients with noncurative resection showed a statistically significant difference(0% vs 11.7%, p=0.034). The survival rate according to TNM stage revealed a statistically significant difference at stages I b and III b (Stage I b - 100% vs 84.5%, p=0.047; Stage III b - 8.8%, vs 28.0%, p=0.049). In conclusion, young patients with stomach cancer who underwent a curative resection showed a similar survival rate to that of whole age patients, and the largest survival rate was for cancer in a relatively early stage. Hence curative resection and early diagnosis are mandatory in young patients with stomach cancer.

The incidence of conjoined twins is so rare that few anesthesiologists have an opportunity of managing them. Especially in Korea, there are only a few reports describing the anesthetic management for surgical separation of newborn conjoined twins. We experienced the successful anesthetic management for surgical separation of thoraco-xiphopagus conjoined twins without any particular problems. After applying the noninvasive monitors (ECG, pulse oximeter), one of the twins (twinA) with congenital heart disease was administered with intravenous ketamine for induction of anesthesia and intubated without neuromuscular blocker. Anesthesia was maintained with N2O-O2 and hand ventilation using Mapleson D breathing circuit. After maintaining airway of the twinA, the twinB was intubated and maintained with the same manner. Eighteen days after the separation procedure, the twinA with congenital heart disease died and the other one, twinB has been alive with normal growth and development.

Purpose:
Pelvic floor injury diagnosis using 3-dimensional (3D) pelvic floor ultrasound or magnetic resonance imaging is unfeasible in many clinics. We assessed the efficacy of a novel diagnostic parameter, the anal canal coronal-sagittal (CS) ratio, for pelvic floor injury on 2D transanal ultrasound.
Methods:
This retrospective study analyzed the data of 126 female patients who underwent 3D pelvic floor ultrasound (including 2D transanal ultrasound) at a pelvic floor center between August and December 2020. The anal canal CS ratio on 2D transanal ultrasound and pelvic floor avulsion injury measurements were recorded for all patients.
Results:
A cutoff anal canal CS ratio of 1.15 was obtained using receiver operating characteristic analysis (sensitivity, 0.820; specificity, 0.763; and area under the curve, 0.838). Patients were categorized into the anal canal CS ratio ≥1.15 and the anal canal CS ratio <1.15 groups. Bilateral pelvic floor avulsion was more common in the anal canal CS ratio ≥1.15 group (n=35, 56.5%), and the incidence of pelvic floor avulsion was significantly different between the 2 groups (P=0.001). Existing parameters of pelvic floor injury, including minimal levator hiatus (P=0.001), levator plate descent angle (P=0.001), and levator ani deficiency score (P=0.001), were statistically different between the 2 groups.
Conclusion
The anal canal CS ratio was an efficient novel parameter that indirectly detected pelvic floor injury in 2D transanal ultrasound. It is a potential alternative indicator for pelvic floor injury on the widely popular 2D transanal ultrasound.
