위염전은 위의 비정상적인 회전으로 생기는데 급성증에서는 진단이 늦어질 경우 치명적일 수도 있으나, 만성증의 경우는 비특이적 위장관 중상을 나타내며, 치료되지 않을 경우 수년 동안 증상이 지속될 수도 있다. 최근 저자들은 소화불량, 식후 상복부 동통을 주소로 내원한 환자에서 만성위염전 2 례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Gastric volvulus is an abnormal rotation of the stomach. Gastric volvulus may present as an emergency or as a chronic condition. Acute volvulus si potentially lethal if unrecognized, while a chronic volvulus may cause symptoms for years if not treated. Gastric volvulus may be more common than previously estimated. Approximately 700 cases have thus far been documented. In patients with vague upper abdominal pain, bloating, vomiting, early satiety and weight loss, chronic gastric volvulus are reported and the related literature reviewed. The clinical presentation, diagnosis, and treatment are treatment are discussed. Features of acute and chronic volvulus are compared.

N/A The common complaints of the acute hepatitis patients studied involved upper gastrointestinal symptoms resembling those of dysmotility. The aim of this study was to evaluate the changes in the electrogastrographic findings and gastric fullness before and after feeding rice soup to patients with acute hepatitis. Methods: The study was performed on 30 patients with acute hepatitis and 41 in a normal control group. Abdominal surface electrogastrography was applied for 30 minutes under a fasting state and 30 minutes after feeding. Results: Patients with acute hepatitis showed a higher level of gastric fullness in both the fasting and postprandial state in comparison to the control group. Significant differences were found in a percentage of postprandial 3 cpm and fasting, and fed tachygastria between the two groups. The percentage of 3 cpm slow wave (unclear) increased by the same amount as the control group after eating. There was no significant difference between the two groups in the power ratio. Conclusion: Upper gastrointestinal symptoms of acute hepatitis did not appear to be related to the change in gastric myoeletrical activity. Other factors including neurological, endocrinological, and emotional should be evaluated.(Korean Jour nal of Gastr ointestinal Motility 2002;8:153-159)

Gastroesophageal reflux disorder (GERD) has been known as a spectrum of disease. Approaching GERD as a spectrum of disease suggests that patients may progress overtime to develop mucosal injury and possible GERD complications. Additionally, erosive esophagitis eventually may develop Barrett`s mucosa and possibly progress to adenocarcinoma. We report a case of Barrett`s esophagus caused by erosive reflux esophagitis in the patient with hiatal hernia. A 55 year-old man who has been diagnosed as reflux erosive esophagitis seven years ago suffered from heartburn and regurgitation symptom. This case may show the natural course of GERD by means of follow-up endoscopy during seven years. (Kor J Neurogastroenterol Motil 2006;12:87-92)

Early detection of colon cancer is more important than the actual treatment of colon cancer. Therefore, screening test for high risk patients in a timely fashion is a main factor in early detection of colon cancer. Stool occult test and stool DNA test, barium enema, CT colonography, colonoscopy are used for screening test of colon cancer. The most effective and sensitive test is colonoscopy; it can detect and remove the premalignant lesion of colon cancer and prevent colon cancer. Although colonoscopy is the best way to early detect colon cancer, the technique to detect and remove the premalignant lesion of colon cancer is essential for early detection of colon cancer. In conclusion, the techniques not only to detect but also remove of premalignant lesion are essentially required for colonoscopist. (Korean J Med 79:104-112, 2010)

PURPOSE. The aim of this study is to evaluate the appropriate impression technique by analyzing the superimposition of 3D digital model for evaluating accuracy of conventional impression technique and digital impression. MATERIALS AND METHODS. Twenty-four patients who had no periodontitis or temporomandibular joint disease were selected for analysis. As a reference model, digital impressions with a digital impression system were performed. As a test models, for conventional impression dual-arch and full-arch, impression techniques utilizing addition type polyvinylsiloxane for fabrication of cast were applied. 3D laser scanner is used for scanning the cast. Each 3 pairs for 25 STL datasets were imported into the inspection software. The threedimensional differences were illustrated in a color-coded map. For three-dimensional quantitative analysis, 4 specified contact locations(buccal and lingual cusps of second premolar and molar) were established. For twodimensional quantitative analysis, the sectioning from buccal cusp to lingual cusp of second premolar and molar were acquired depending on the tooth axis. RESULTS. In color-coded map, the biggest difference between intraoral scanning and dual-arch impression was seen (P<.05). In three-dimensional analysis, the biggest difference was seen between intraoral scanning and dual-arch impression and the smallest difference was seen between dual-arch and full-arch impression. CONCLUSION. The two- and three-dimensional deviations between intraoral scanner and dual-arch impression was bigger than full-arch and dual-arch impression (P<.05). The second premolar showed significantly bigger three-dimensional deviations than the second molar in the three-dimensional deviations (P>.05).

Background/Aims: We investigated the prevalence, associated factors, and comorbidities of high-risk obstructive sleep apnea (OSA) as determined by the STOP-BANG questionnaire in a Korean adult population. Methods: Data were obtained from 7,650 adults (aged ≥ 40 years) who participated in the Korea National Health and Nutrition Examination Survey (2019−2020). Multiple logistic regression analyses were used to evaluate the association of socioeconomic status, lifestyle related factors, and comorbidities with high-risk OSA (STOP-BANG score, 5−8). Results: The prevalence of high-risk OSA according to the STOP-BANG questionnaire was 12.0 %. Older age, male, current smoking, heavy alcohol consumption, and more comorbidities were associated with higher STOP-BANG scores. In multivariable adjusted analysis, diabetes mellitus (DM) (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.25 to 1.97), hypertension (OR, 4.81; 95% CI, 3.88 to 5.97), and obesity (OR, 2.02; 95% CI, 1.60 to 2.56) were associated with high risk of OSA, and when hypertension, DM, and obesity were combined, the risk increased synergistically (OR, 3.88; 95% CI, 2.94 to 5.11). Conclusions: According to the STOP-BANG questionnaire, the high risk of OSA was more common in males, and was associated with chronic metabolic disease, particularly in those with DM, hypertension, and obesity combined. Active OSA screening, prevention, and management may be beneficial to improving health outcomes related to OSA in these populations.

이 논문에서는 효율적인 2D 방식의 심전도 신호 압축 방법을 제안한다. 1D 심전도 신호는 2D 신호로 변환된 후 주기와 복잡도를 바탕으로 정렬되고 상호간의 상관 관계를 적용한다. 그 다음 불연속이 발생하는 지점을 기준으로 각 구간을 분할하고 주기의 평균으로 정규화 한 후 보통의 영상 신호를 압축하는 방식과 유사한 방식으로 정렬된 2D 신호를 압축한다. 압축 방식으로는 JPEG 2000이 사용되었으며 실험 데이터는 심전도 압축에서 표준화되어 사용되는 MIT-BIH arrhythmia database를 사용하였다. 제안된 방법은 기존의 2D 심전도 압축 방식과 비교하여 보다 개선된 성능을 보여 준다. In this paper, we propose an effective compression method for electrocardiogram (ECG) signals. 1-D ECG signals are reconstructed to 2-D ECG data by period and complexity sorting schemes with image compression techniques to increase inter and intra-beat correlation. The proposed method added block division and mean-period normalization techniques on top of conventional 2-D data ECG compression methods. JPEG 2000 is chosen for compression of 2-D ECG data. Standard MIT-BIH arrhythmia database is used for evaluation and experiment. The results show that the proposed method outperforms compared to the most recent literature especially in case of high compression rate.
