Angiographic findings were analysed in 22 cases of coronary occlusive disease which were selected from 50 cases of coronary arteriographies done in Department of Radiology, Seoul National Un iversity Hospital from September, 1981 to August, 1984. There were 16 cases of single vessel disease, in which 12 were LAD involvement and 4 were RCA involvement, 2 cases of two vessel and 4 cases of three vessel disease. Site, degree and extent of stenotic involvement in those occlusive coronary diseases were anal ysed with review of literature for selective coronaryarteriography. Since coronary arteriography is the final and accurate examination for the evaluation of occlusive coronary arterial disease, it is expected to be widely used for the diagnosis of occlusive coronary arterial disease which is rapidly increasing recently in this country.

Variations of spinal nerue compositions, which giue rise to the variable motor and sensory component, occured at the terminal branches of brachial plexus. This study performed to investigate the spinal nerve compositions of the main terminal branches of the brachial plexus in 32 sides of Korean adults. The main terminal branches contained the musculocutaneous, median, ulnar, radial and axillary nerves. The obtained results were as follows. The spinal nerve compositions of musculocutaneous nerve appeared as two types. The most frequent type was composed of C5, C6 and C7 at 75.0%. The mean diameter of C5 and C6 was 1.68+/-0.21 mm and 1.66+/-0.40 mm, respectively. The median nerve appeared as two types. The most frequent type was composed of C6, C7, C8, T1 components at 87.5%. The mean diameter of C7 was the thickest at 2.64+/-0.48 mm and C5 was most thin at 0.28+/-0.04 mm. The ulnar nerve appeared as four types. The most frequent type was comprised with C7, C8 and T1 at 75.0%. In the mean diameter, C8 was the thickest with 2.64+/-0.57mm and T1 was most thin with 0.06+/-0.56 mm. The radial nerve appeared as four types. The most frequent type was comprised from C5 to T1 at 43.7%. In the mean diameter, C7 was the thickest at 2.70+/-0.52 mm. The axillary nerve appeared as two types. The frequentest type was comprised with C5, C6 and C7 at 56.2%. In the mean diameter, C6 was the thickest at 1.73+/-0.56 mm. From the obtained results, spinal nerve compositions of the main terminal branches of the brachial plexus were more variable than the description of the anatomic textbook.

This study aimed to investigate the frequency of dental visits after coronavirus disease 2019 (COVID-19) in children and adolescents in comparison to that of adults. The data on the number of dental visits on the basis of different classification and treatment codes for all the age groups were provided by the Health Insurance Review and Assessment Service from January 2017 to December 2020. To reduce the impact of the population change, dental visits per 1000 people was used. After the start of the pandemic, dental visits per 1000 people decreased in all age groups when analyzed for the diseases of pulp and periapical tissues classification code and dental visits per 1000 people decreased over 5 years age groups when analyzed for the pulp treatment code. Regarding the restorative treatment code, visits in the 0 - 19 years age group decreased after the pandemic. Based on the comparison of the number of confirmed COVID-19 cases to that of monthly dental visits by treatment codes, the change rate of pulp and restorative treatments gradually decreased after the waves of the pandemic in February and August 2020 in Korea. Furthermore, dental visits per 1000 people for gingivitis and periodontal disease classification code increased after the pandemic in all age groups. The rate of decrease in dental visits per 1000 people for restorative treatments in children and adolescents was higher than that in adults. The rate of decrease in the number of dental visits for multi-visit pulp treatments showed a rapid decrease as compared to that of 1-visit pulp treatments after the pandemic. This study identified changes in the number of dental visits of children and adolescents after COVID-19 transmission in comparison to that observed in adults.

Objectives: The importance of public healthcare has been further emphasized by the arrival of the era of super-aged societies. This study investigates the landscape among oral health professionals, focusing on the concept development of the public oral health care (POHC) and essential oral health care (EOHC). Methods: A questionnaire survey of oral health professionals was conducted at six associations or societies who have an interest in POHC from December 21 to December 29, 2022. Chi-squared and logistic regression analyses were adopted to identify significant differences between the responses according to general characteristics. Significant differences were considered at a P-value of 0.05. Results: A total of 100 oral health professionals (48 dentists and 52 dental hygienists) participated in this study. The results revealed that there is a need for improvement of the POHC and the establishment of concepts related to the POHC and EOHC. The agreement rate was 90%, 85%, and 86% for the responsible organization, the target object and field, and the concept in the definition of the POHC, respectively. In the case of the construction of the EOHC, the agreement rate was 91% for “Quality of life,” and 85% for “Life and safety.” Among the community oral health programs as the POHC programs, “Oral health education program” showed the highest agreement rate. In healthcare institutions that are capable of providing the POHC services, “Oral health center in the public health center” had the highest agreement rate. Conclusions The POHC would be reasonable to define to ensure universal access to oral healthcare services for all citizens. In the case of EOHC, further research is needed to establish terminology and specific concepts in the future. This study could contribute valuable insights to the field of the POHC in an era of super-aged societies. As further research, more oral health professionals need to participate in the POHC-related policy and health care system.

PURPOSE: The purpose of this study was to analyze the radiologic findings of primary epiploic appendagitis, with particular attention to the correlation of ultrasonographic, clinical, CT, MR and surgical findings. MATERIALS AND METHODS: Among 14 patients with primary epiploic appendagitis who presented with the rapid onset of a very localized pain and tenderness, we performed ultrasonography in all, CT in eight, and MRI in four of these eight. Surgery was performed in two patients. Follow-up examinations were performed using US, CT and MRI (n=2), US and CT (n=2), US alone (n=2), and with regard to clinical features (n=12). RESULTS: US performed in 14 patients revealed the presence in all of small, well-defined, ovoid, noncompressible hyperechoic (n=12) or isoechoic (n=2) solid masses attached to the colonic wall, without bowel wall change and without communication with bowel lumen. CT performed in 8 patients showed varying hyperattenuating fatty lesions in the same location in the abdomen, without other inflammatory process. MRI findings of four patients were helpful for further evaluation of internal architecture. CONCLUSION: In primary epiploic appendagitis, US findings were sufficiently characteristic to allow accurate diagnosis and valuable for the differential diagnosis of other acute conditions of the abdomen.

PURPOSE: Omega-3 fatty acid is known for immunonutrition in that it has anti-inflammatory properties and improves the patients' immune function. The objective of this study was to determine the effects of a fish oil-based lipid emulsion for adult patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). METHODS: This was a retrospective study of 90 adult allogeneic HSCT patients from July 2011 to June 2015. The patients were divided into two groups according to the lipid type provided; fish oil group (FO group, n=55) and non-fish oil group (NFO group, n=35). The demographics, parenteral nutrition and lipid emulsion duration, length of hospital stay (LOS), weight change, 30 day mortality, survival period, incidence of acute graft-versus-host disease (aGVHD), neutropenic fever, sepsis, and re-hospitalization were collected from the electronic medical records. RESULTS: The patients' characteristics including age, sex, body mass index, and underlying disease were similar in the two groups. The incidence of aGVHD and infectious complications, mortality, LOS, re-hospitalization were also similar. The FO group showed weight gains, whereas the NFO group showed weight loss (FO vs. NFO=0.34% vs. -1.08%, P=0.245). CONCLUSION: The clinical outcomes were similar in the two groups but there was a tendency for gain weight in the FO group. A large, well designed study, and a dosing study will also be needed to determine the optimal dose range for HSCT patients.

BACKGROUND: To identify the prevalence and risk factors of poststroke depression(PSD) in patients admitted to department of rehabilitation medicine after stroke, to compare functional recovery of depressed patients and that of non-depressed patients, and to recognize the most useful depression scale that can predict functional recovery. METHOD: Of the hospitalized stroke patients in the department of Rehabilitation Medicine, 24 patients who were communicable were included in this study. To evaluate PSD, Beck depression inventory(BDI) and Korean form of Geriatric depression scale(KGDS) were used as self-rating scales. Hamilton depression scale(HAM-D) was used as an objective scale. Functional Independence measure(FIM) was measured at admission and discharge to evaluate functional recovery. RESULTS: In the 24 subjects, 17 patients(70.8%) and 9 patients(37.5%) were depressive by BDI and HAM-D. Of the 19 elderly patients, 16(84.2%) were depressive by KGDS. Factors such as age, level of education, religion, etiology or location of stroke were not significantly associated with PSD. And FIMscores were not significantly different in the depressed patients and non-depressed patients. The correlation coefficients of BDI, KGDS, HAM-D and FIMgain or efficiency were not statistically significant. CONCLUSION: The prevalence of PSDwas high in our study, but no association was found between PSD and functional recovery.

Background: Preoperative concerns of patients undergoing total hip arthroplasty (THA) and their complaints during the initial postoperative period are not well investigated. We evaluated preoperative concerns of patients and patient-perceived problems during the operation and initial 5 days after the operation. Methods: One hundred and thirty-two patients, who underwent primary THA at a tertiary referral hospital, were surveyed using a questionnaire and a face-to-face interview 1 day before the operation, operation day, and postoperative days 1, 2, 3, and 4. The severity of pain was assessed daily using a visual analog scale. Results: The most common preoperative concern was the severity of pain after the surgery (65.2%), followed by the need of transfusion (34.8%) and postoperative rehabilitation (32.6%). Among 29 patients who could recall the experience during the operation, 12 (41.4%) suffered from shoulder pain on the contralateral side, and 6 (20.7%) answered that hammering sound had been annoying. After returning to the ward, 29 patients (22.0%) suffered from nausea, 8 (6.1%) complained of back pain, and 7 (5.3%) had ipsilateral knee pain. On postoperative day 1, 7 patients (5.3%) had persistent back pain, 8 (6.1%) had headache, and 5 (3.8%) suffered from nausea. On postoperative day 2, nine patients (6.8%) complained of radiating pain due to aggravation of preexisting spinal stenosis, 7 (5.3%) complained of weakness of the hip flexor due to periarticular injection of ropivacaine during the operation, and 5 (3.8%) had dressing-related skin problem at the wound. On postoperative days 3 and 4, patients had no problem other than hip pain. The mean pain score was the highest (3.1 ± 1.0) on postoperative day 1. Conclusions The results of this study might provide information needed to solve problems and improve satisfaction of patients undergoing THA.
