The osteopoikilosis is commonly known as harmatoma in which metaphyseal and epiphyseal area of long bones and the bone of pelvis, hands, feet and et al, contain islands of dense cortical bone with normal Harversian system without any symptoms. The radiologic findings of the osteopoikilosis is multitude of oval or well-circumscribed areas of increased density, 2 to 10 mm in size, in symmetrical distribution and normal uptake in bone scan. Buschke-Ollendorff syndrome, which is transmitted by autosomal dominant, is characterized by the association of osteopoikilosis and connective tissue nevi which are popular and symmetrically distributed lesions on chest, back, buttock, thigh or arm. Authors report three Buschke-Ollendorff syndrome, studied by CT scan, MRI, bone scan and bone and skin biopsy, among five patients associated with osteopoikilosis found by simple radiologic study from ten members in one family with their pedigree.

Purpose: To report a satisfactory clinical outcome of hemorrhagic retinal macrocyst with retinal detachment after pars plana vitrectomy and silicone oil injection. Case summary: A 33-year-old man visited our clinic with a 1-week history of visual disturbance in his left eye. His ocular and medical history were unremarkable, and best-corrected visual acuity (BCVA) in the left eye was 20/40. Fundoscopic examination of the left eye showed a hemorrhagic retinal macrocyst that was well-demarcated, semi-transparent, dome-shaped, and larger than 8 disc diameters at the superonasal location, with macular-off retinal detachment. B-scan ultrasonography also confirmed the presence of an intra-retinal cystic lesion with internal mobile echogenic signals representing blood. The patient underwent 23-gauge pars plana vitrectomy, barrier laser photocoagulation around the retinal tear and boundary of the cyst, and silicone oil injection, without any other additional procedures for the hemorrhagic retinal macrocyst. After the surgery, the patient stayed in the face down position for two weeks. Three months postoperatively, a completely collapsed hemorrhagic retinal macrocyst with successful retinal reattachment was observed. Six months later, the BCVA in the left eye had improved to 20/30. One year later, even after silicon oil removal, the collapsed hemorrhagic retinal macrocyst and reattached retina remained stable. Conclusions A hemorrhagic retinal macrocyst with retinal detachment was successfully treated with pars plana vitrectomy and silicone oil tamponade.

BACKGROUND/OBJECTIVES: The diversity of meal provision places has increased in recent years and sodium intake can vary depending on where meals are eaten, particularly in large cities. In this study, an analysis of the recent trends in sodium intake was performed and a comparison of sodium intake level according to meal provision place among citizens of Seoul was performed. SUBJECTS/METHODS: Data from a 24-h recall dietary intake survey from the 2010–2019 Korea National Health and Nutrition Examination Survey (KNHANES) were used in order to determine the trends in sodium intake among citizens of Seoul, aged 3–74 years old. (n = 11,811). The trend of daily sodium intake was presented in absolute amount and proportion compared to the chronic disease risk reduction intake (CDRR) for each selected characteristic. A comparison of sodium intake level according to meal provision place by sex and age groups as a total amount per meal (mg), density per meal (mg/1,000 kcal), and proportion of the daily sodium intake was performed using the 2016–2019 KNHANES. RESULTS: Sodium intake levels showed a downward trend from 2010–2019. The highest level of sodium intake was observed for subjects aged 30–49, and the level for males aged 30–49 was 202.8% higher than the CDRR. Results of the analysis of sodium intake per meal according to meal provision place showed that the highest sodium intake was in the order of restaurant meal (RM) > institutional foodservice (IF) > home meal (HM) > convenience food (CF). A higher sodium density (mg/1,000 kcal) was observed for IF compared with RM in most adults. Adults aged over 50 years old consumed more than half of the daily sodium in HM. CONCLUSION Significant variation in the level of sodium intake was observed according to sex and age groups, therefore, different approaches and nutrition policies based on meal provision place are needed.

Purpose: Preoperative tumor size is associated with clinical stage, treatment plan and even survival rate of patient. We investigated the accuracy of tumor size estimation between magnetic resonance imaging (MRI) and ultrasonography (US) findings, comparing these with pathologic tumor size in the diagnosis of early breast carcinoma. Methods: Between 2011 and 2016, 136 patients with early breast cancer were analyzed and their tumor size on US and MRI findings were compared with their pathologic tumor size retrospectively. The background parenchymal enhancement of MRI was categorized as minimal, mild, moderate, and extreme. The patients who underwent neoadjuvant chemotherapy, had positive resection margins, underwent excisional biopsy for cancer diagnosis, and had non-mass lesions on MRI scans, were excluded. Results: In all, 83.1% of the cases showed concordance between MRI findings and pathologic tumor size within 0.5cm. MRI overestimated the findings by 10.3% and underestimated them by 6.6%; 78.7% showed concordance between US findings and pathologic tumor size within 0.5cm. US overestimated the findings by 5.9% and underestimated them by 15.4%. The tumor size on MRI (r=0.87) showed a stronger correlation to the pathologic tumor size than that on US (r=0.64) in early breast cancer patients. US had a tendency to underestimate the tumor size. The degree of breast parenchyma did not affect the accuracy of the measurement of preoperative tumor size. Conclusion MRI is relatively more accurate than US for assessing preoperative tumor size in breast cancer patients. US tends to underestimate tumor size.

It is well known that troponin T (below TnT) is present in the myocardial cells and released during myocardial damage, so it`s very specific enzyme to myocardium. Availability of cardiac specific TnT in assessing perioperatively myocardial damage was evaluated from 34 open heart surgery patients. They consisted of 11 ischemic heart, 13 acquired valvular heart and 10 congenital heart cases. Patients were divided into two groups, group A (patients with myocardial damage) and group B (patients without myocardial damage), according to the symptom of chest pain suspecting angina and the ECG findings of ST segment and T wave changes which show myocardial ischemia and injury. Serum TnT levels were measured by enzyme immunoassay method preoperatively, immediately postoperatively, postoperative day 1, day 2, day 3, and day 7. We observed and analyzed the changes of serum TnT levels in two groups and compared the serum TnT levels with CK-MB levels measured at the same time. In group A, serum TnT levels showed 1.37+/-0.26microgram/L, 3.16+/-0.66microgram/L, 2.39+/-0.74microgram/L, 2.49+/-0.76microgram/L, and 1.23+/-0.60microgram/L, immediate postoperatively, postoperatively day1, day2, day3, and day7, respectively. It was observed there were significant differences compared with those of group B (0.38+/-0.04microgram/L, 0.34+/-0.05microgram/L, 0.25+/-0.03microgram/L, 0.24+/-0.04microgram/L, and 0.11+/-0.03microgram/L) during identical periods (p<0.01). Serum CK-MB level in group A significantly elevated to 145.04+/-35.08 IU/L on the postoperative day 1 compared to group B (31.28+/-5.87 IU/L, p<0.05), However, it stiffly decreased from day 2 and returned to preoperative level at day 3. When serum TnT level more than 1.0microgram/L is thought to reflect myocardial damage, serum TnT had 100% of sensitivity and 87% of specificity in diagnosing the postoperative myocardial damage (p<0.01). I conclusion, serum TnT levels increased significantly at very early stage of myocardial damage and persisted much longer period than CK-MB. This suggests that serum TnT has more advantage and availability in assessing the perioperatively myocardial damage than any other tests.

A clinical evaluation was performed on 11 cases of the cardiac rupture by blunt chest trauma at the department of thoracic and cardiovascular surgery, Yeungnam University Hospital during the period from July, 1993 to May, 1995. The results were as follows ; The sex distribution was 8 mem and one women, and mean age was 41 years old. The causes of accident was traffic accident in most cases. And then one case was cultivator accident and another one was fall down. The average times from trauma to admission was 139 minutes and the patients that transferred via other hospitals have relatively long average times to 227 minutes. The average times from admission to operation was 117 minutes and we consumed 25 minutes for the preoperative preparation. The sites of injury were 7 cases in the right heart and 3 cases in the left heart. There were symptoms and signs of the cardiac tamponade (dyspnea, chest pain, nausea/vomitus, neck vein distention & hypovolemic shock) at admission and in most of them typical symptoms and signs of a tamponade appeared. Surgical approach was performed with median sternotomy in 10 cases. Subxiphoid pericardial window was created in one case. Another case which was very difficult in surgical procedure was operated under cardiopulmonary bypass and the result was good.

PURPOSE: To evaluate the effect of gadoxetic acid on the measurement of the stiffness value of MR elastography (MRE) used to evaluate hepatic fibrosis (HF). MATERIALS AND METHODS: MRE was obtained in 32 patients with clinically suspected chronic liver disease, both before and after injection of gadoxetic acid. Two independent reviewers measured the stiffness values of the liver parenchyma on elastograms. The mean liver stiffness values were compared in the pre- and post-contrast MREs using the paired t-test. Intra-rater and inter-rater correlation was assessed using the intraclass correlation coefficient (ICC). The accuracy, sensitivity, and specificity of both pre- and post-contrast MREs was evaluated for the diagnosis of significant HF (> or = F2) using cut off value of 3.1 kPa. RESULTS: There were no significant differences in the stiffness values of the liver parenchyma on pre- and post-contrast MREs (p = 0.15 and 0.38 for each reader, respectively). Regarding intra-rater correlation, excellent agreement was noted on rater 1(ICC = 0.998) and rater 2 (ICC = 0.996). Excellent correlation regarding the measured stiffness values was noted on both pre- and post-contrast MREs (ICC = 0.988 for pre-contrast, ICC = 0.993 for post-contrast). The accuracy, sensitivity, and specificity of the pre- and post-contrast MREs for differentiating significant HF (> or = F2) from < or = F1 were same as 71%, 60%, and 100%, respectively. CONCLUSION: As there was no significant difference in the stiffness measurements seen on MREs before and after administration of gadoxetic acids, it is therefore acceptable to perform MRE after contrast injection in order to evaluate HF.
