This study was performed to examine if the effects of collagen supplementation from pork skin could improve the sex steroid hormone, serum lipid and skin crack in Korean middle-aged women. Middle-aged women (40-55 years) who were not diagnosed with any type of disease were included in this study and thirty subjects were randomly assigned to a control group (n = 15) or a collagen supplemented group (n = 15). The collagen supplemented group ingested collagen flour 2 g, 3 times a day for 12 weeks. We measured serum collagen, estrogen, estradiol, estriol, progesterone, total cholesterol, triglyceride, HDL-cholesterol and LDL-cholesterol concentration. The collagen supplementation group had significantly increased serum collagen (p < 0.05) compared with the control group. In addition, skin crack was improved. But, there were no differences for sex steroid hormone and lipid profile in control and collagen supplemented groups. The result of the present study demonstrated that supplementation of 6 g collagen per day for 12 weeks can give beneficial effects on skin crack reduction and serum collagen concentration.

Purpose: The objective of this study was to analyze the effects of non-pharmacological interventions on cancer patients with sleep disorder. Methods: A total of 4,246 studies published between 2000 and 2018 were identified by searching NDSL, RISS, Koreamed, PubMed, EMBASE, Cochrane Library, and CINAHL. Seventeen of these studies were selected for inclusion in the meta-analysis.Data were analyzed using the Comprehensive Meta-Analysis (CMA) Ver. 3.4.1 program, and the effect sizes were shown using Hedges’ g score. Results: Intervention studies included 8 studies on exercise, 4 studies on cognitive-behavioral therapy, 2 studies on music, and 1 study each on aromatherapy, massage, and mindfulness-based stress reduction. The overall controlled effect size was .78 (95% Confidence Interval=.40, 1.16, Z=4.02, p<.001), using a random effects model. Conclusion Through this study, it was found that the effects of exercise (walking), aromatherapy, massage, and music intervention were all statistically significant. As such, the findings of this study provide evidence supporting the incorporation of various non-pharmacological interventions into nursing practice to improve sleep quality in patients with sleep disorder.

PURPOSE: The purpose of this study was to identify relationships between quality of sleep, symptom cluster, depression, environmental disorder, and quality of life among hospitalized cancer patients. METHODS: The subjects were 114 patients who underwent chemotherapy for colon cancer, gastric cancer, gynecologic cancer and breast cancer. They were recruited from the cancer center of a university hospital. Data were collected from August 4th to 30th, 2011. The questionnaires included the Korean sleep scale A (quality of sleep), MDASI-K (symptom cluster), the environmental sleep disturbing scale, Zung's depression scale, and the Korean version of EORTC QLQ-C30. The collected data was analyzed by t-test, ANOVA, multiple regression analysis using the SPSS 19.0 program. RESULTS: Functional QOL was negatively associated with symptom QOL (r=-.798, p<.001). Symptom cluster, depression, & spouse (46.3%) were the most powerful predictors for functional QOL (46.3%) and symptom QOL (53.4%). CONCLUSION: It is evident that oncology nurses need to evaluate two dimensions of quality of life for cancer patients, for example, functional and symptom QOL. We recommend nurses develop specific protocols for relieving physical symptoms and alleviating depression, and furthermore test the effectiveness of them.

Exercise testing with Thallium imaging is widely used for the noninvasive evaluation of patients suspected of having coronary artery disease. However, many patients referred for stress testing connot exercise adequately for either physical or psychological reasons, and as a result may have nondiagnostic or suboptimal test results. Intravenous dipyridamole in conjunction with Thallium imaging is as effective alternative method without exercise. But, myocardial imaging using the standard scintillation camera technique(planner view) is hampered by superposition of proximal & distal cardial walls and by the segmental nature of myocardial ischemia. For this reason, Single Photon Emission Computed Tomography(SPECT) reslut in high specificity & sensitivity rates for the detection of coronar artery disease compared with conventional technique. So we performed dipyridamole Th-201 myocardial scintigraphy on 25 subjects who have suspicious angina or myocardial infarction instead of exercise Th-201 myocardial scintigraphy, and compared SPECT view with conventional plannar view. The results obtained are as follows : 1) T1-201 scintigraphic findings in 17 patients with suspicious angina were as follows ; redistribution defect was seen in 4 cases in plannar view and 13 cases in SPECT view. 2) T1-201 scintigraphic findings in 8 patients with myocardial infarction were as follows ; in planner view, perfusion defect was seen in all cases and 1 cases of them, redistribution defect was accompained, and in SPECT view, perfusion defect was seen in all cases and 6 cases of them, redistribution defect was accompained. 3) During dipyridamole infusion, the mean systolic & diatolic pressure decreased from 133+/-22.7/86+/-13.5 to 121+/-23.9/78+/-13.1mmHg and the heart rate increased from 68+/-12.4 to 84+/-12.4beats/min. 4) Adverse effects of dipyridamole were noted in 14(56%) of the subjects, but in 12 of these, the symptoms were mild in severity and subsided spontanously. To summarize, Dipyridamole-201 myocardial imaging is a useful and test for coronary artery disease, and the new tomographic technique, SPECT view, is more useful than the conventional plannar view.

Arteiovenous malformation of the uterus is an extremely rare and becomes one of the causes of severe uterine bleeding. Because uterine bleeding can be aggravated with diagnostic dilatation and curettage, an accurate diagnosis should be achieved before the intervention. This malformation may be congenital or acquired. In the past, the diagnosis is usually made retrospectively after hysterectomy, however, recently it may be made before management by ultrasound, doppler ultrasound, pelvic angiography, magnetic resonance imaging, etc.. We have experienced one case of arteriovenous malformation of the uterus, which is presented with a brief review of the literatures.

A reduced retroversion angle of humeral head may predispose to recurrent anterior shoulder dislocation and may also be a factor in persistent instability after soft tissue procedures. Rotation osteotomy of proximal humerus is one of many surgical modalities proposed for recurrent anterior shoulder dislocation. To support such an operation, fundamental knowledge of shoulder anatomy is essential. The semi-axial view by Soderlund have been regarded as simple and reliable method for measuring humeral head retroversion angle. The purpose of this study was to evaluate validity of the semi-axial view and to assess reference values for humeral head retroversion angle in Korean. Humeral head retroversion angle was determined from 80 healthy subjects, 48 men and 32 women. Radiographs which shown less than 10degrees between humeral shaft axis and epicondylar axis were defined as acceptable radiographs by Soderlund. Acceptable radiographs were selected and two orthopedic surgeons measured retroversion angle, separately. Acceptable radiographs were obtained in only 70 shoulders (43.8%). The mean angle was 35.2+/-8.24degrees for dominant hand and 32+/-6.27degrees for nondominant in Korean. The mean angle was 35.3+/- 7.78degrees for right side and 31.9+/-6.8degrees for left. The interobserver difference was 2.9degrees. The semi-axial view by Soderlund was not reproducible solely. But if correct arm position is considered, the method presented is easy to use daily.

OBJECTIVE: To compare motor evoked potential stimulated by round coil with that stimulated by butterfly coil. METHOD: Thirty control subjects were studied using magnetic stimulation by round coil and butterfly coil. Stimulation sites were cortex, cervical spine and lumbar spine. Recording electrodes were located on biceps brachii, abductor digiti minimi and tibialis anterior muscles. RESULTS: There were no significant differences between latencies of motor evoked potentials using round coil and those using butterfly coil in all tested muscles. In all muscles, amplitudes were significantly higher in stimulation with round coil than with butterfly coil. Above results were shown in both cortical and spinal motor evoked potentials. There were significant correlations between latencies of motor evoked potentials, heights, and arm lengths. CONCLUSION: We can record motor evoked potentials more easily with round coil than butterfly coil.

BACKGROUND/AIMS: The prognosis of primary hepatocellular carcinoma is extremely poor because of its large size, portal vein thrpombosis, extrahepatic metastasis and underlying liver cirrhosis. The aim, of this study is to evaluate the usefulness of ultrasound screening test for early detection of hepatocellular carcinoma in high-ridk populations. METHODS: We analysed 119 patients who were diagnosed with hepatocellular carcinoma by ultrasonography screening test in Yonsei University Severance Hospital from the period of January 1990 to December 1996. RESULT: The mean follow-up duration to the diagnosis of hepatocellular carcinoma was 30 months (range 3-75). The number of patients with single lesion was 89(75%). The mean diameter of the tumor was 3.0 cm (range 1-10) , 82 patients (70%) had masses measured less than 3cm in diameter. The Number of patients with elevated serum alphafetoprotein level above 400ng/ml was 29(25%). The median survival was 28 months in screening group, significant compared with 7 months in control group (p<0.001). CONCLUSIONS: Ultrasound follow-up in high-ridk group of hepatocellular carcinoma mede it possible to detect small tumors in a high percentage of cases. This may lead to an increase in the number of potentially curable tumors and hence an increase in the overall survival rate. So ultrasound screening test is important in the high-ridk group of hepatocellular carcinoma.

BACKGROUND: Despite the enormous amount of basic research on neuropathic pain, there is the lack of an objective diagnostic test for complex regional pain syndrome (CRPS). The aim of this study was to evaluate the usefulness of cold stress thermography in the diagnosis of CRPS. METHODS: The study involved 12 patients with CRPS type 1, according to the IASP criteria, who were compared with 15 normal healthy volunteers. All subjects underwent thermographic examination under baseline conditions at 21degrees C. A cold stress test (CST; 10degrees C water for 1 minute) was then applied to both hands below the wrists, immediate, and after 10 and 20 minutes. RESULTS: The temperature asymmetry between the patients with CRPS and the volunteers showed significant discrimination at the baseline and after a 20 minute recovery period from the CST. Among the study subjects having temperature asymmetry of both hands of less than 1degrees C (8 out of 12 CRPS patients and 14 out of 15 volunteer), 7 (87.5%) of the 8 CRPS patients and 3 (21%) of the 14 volunteers showed a temperature difference of more than 1degrees C after the 20 minute recovery period. The actual temperature values during the four periods did not discriminate between the patients with CRPS and the volunteers. CONCLUSIONS: Thermography, under the CST, could be a more objective test for the diagnosis of CRPS. A temperature asymmetry greater than 1degrees C during the 20 minute recovery period following CST provides strong diagnostic information about CRPS, with both high sensitivity and specificity.
