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.

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.

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.

Objectives: Cognitive impairment is a fundamental symptom of schizophrenia, an often-overlooked aspect of the disorder that has gained recent attention due to its direct relation with functional outcomes and implications for medical and social costs. This study aims to investigate gender differences in cognitive function among patients with schizophrenia using Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV). Methods: Data were collected from inpatients and outpatients treated at Presbyterian Medical Center between January 1, 2019, and December 31, 2023. Patients diagnosed with schizophrenia underwent evaluation with the K-WAIS-IV. Multivariate analysis of variance was utilized to assess cognitive differences between men and women participants, while correlation analysis was performed to explore associations between cognitive performance and clinical data. Results: Among 101 candidates, 26 male and 26 female patients were selected for analysis of their K-WAIS-IV scores and clinical data. The results revealed no statistically significant differences in cognitive function between male and female patients concerning Full-Scale Intelligence Quotient (FSIQ) and the four index scores: Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI), Working Memory Index (WMI), and Processing Speed Index (PSI). A trend indicating preserved verbal intelligence relative to performance intelligence was observed. Additionally, the VCI exhibited a positive correlation with age, while both FSIQ and PSI demonstrated positive correlations with years of education. Conclusion The findings of this investigation suggest that there are no significant differences in cognitive function between male and female patients with schizophrenia via K-WAIS-IV. Given the heterogeneity of the sample and potential limitations of the neurocognitive assessments employed, further research utilizing more targeted methodologies and sensitive measures is warranted.

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.

BACKGROUND: Normalized cerebral blood volume (nCBV) can be measured using manual or semiautomatic segmentation method. However, the difference in diagnostic performance on brain tumor differentiation between differently measured nCBV has not been evaluated. PURPOSE: To compare the diagnostic performance of manually obtained nCBV to that of semiautomatically obtained nCBV on glioblastoma (GBM) and primary central nervous system lymphoma (PCNSL) differentiation. MATERIALS AND METHODS: Histopathologically confirmed forty GBM and eleven PCNSL patients underwent 3T MR imaging with dynamic susceptibility contrast-enhanced perfusion MR imaging before any treatment or biopsy. Based on the contrast-enhanced T1-weighted imaging, the mean nCBV (mCBV) was measured using the manual method (manual mCBV), random regions of interest (ROIs) placement by the observer, or the semiautomatic segmentation method (semiautomatic mCBV). The volume of enhancing portion of the tumor was also measured during semiautomatic segmentation process. T-test, ROC curve analysis, Fisher's exact test and multivariate regression analysis were performed to compare the value and evaluate the diagnostic performance of each parameter. RESULTS: GBM showed a higher enhancing volume (P = 0.0307), a higher manual mCBV (P = 0.018) and a higher semiautomatic mCBV (P = 0.0111) than that of the PCNSL. Semiautomatic mCBV had the highest value (0.815) for the area under the curve (AUC), however, the AUCs of the three parameters were not significantly different from each other. The semiautomatic mCBV was the best independent predictor for the GBM and PCNSL differential diagnosis according to the stepwise multiple regression analysis. CONCLUSION: We found that the semiautomatic mCBV could be a better predictor than the manual mCBV for the GBM and PCNSL differentiation. We believe that the semiautomatic segmentation method can contribute to the advancement of perfusion based brain tumor evaluation.
