PURPOSE: To evaluate the clinical features of the patients with episcleritis and scleritis. METHODS: Retrospective chart review was performed for above patients that had been followed from 1986. 8. 8 to 2001. 6. 4. RESULTS: The number of patients with episcleritis was 17 (49%) and that of scleritis was 18 (51%). Ocular complication occurred in 59% of patients with episcleritis and 72% of patients with scleritis. Keratitis was the most common ocular complication. No patient with episcleritis had a decrease in visual acuity, whereas 33% of patients with scleritis did. Systemic diseases were found in 69% of episcleritis whereas 77% of patients with scleritis associated with systemic diseases. Rheumatoid arthritis was the most common one in both groups of patients. CONCLUSIONS: Ocular complications, systemic diseases, and decrease in visual acuity are associated more of commonly with scleritis than episcleritis. When scleritis is suspected, careful examinations for associated ocular complications should be performed and be followed with history taking and evaluation for associated systemic disease.

Acute aortic dissection is the most common catastrophic illness of the aorta. Left untreated, about 75% of patients with dissections involving the ascending aorta die within 2 weeks of an acute episode, but survival may be significantly improved by the timely institution of diagnostic modalities and appropriate medical and surgical therapy. But, approximately 10-20% of patients with acute aortic dissection present with a clinical picture of acute myocardial infarction. This sometimes can not only delay the diagnosis and adequate treatment of acute aortic dissection but also inappropriately treat with thrombolytic agents and anticoagulants which result in rapid deterioration of clinical condition of patient. We report a case of acute aortic dissection with dynamic ST changes in electrocardiogram which resulted in delay of accurate diagnosis and adequate treatment of acute aortic dissection.

In the last 30 years, technical improvements have directly contributed to expanding sonographic breast imaging applications into the most important adjunctive imaging modality for breast evaluation. Most of these advances have related to improvements in sonographic gray-scale image resolution and contrast, but some applications such as color Doppler imaging, elastography, optical imaging, or three-dimensional ultrasounds have resulted in sonographic information that is uniquely different from grayscale imaging. The current spectrum of new breast sonographic techniques not only offers information uniquely different from gray-scale imaging but also involves hardware advances that affect the method of image production. In this article, we discuss the current trends in breast ultrasonography focusing on the advances to further improve accuracy for breast lesion diagnosis.

Platelet transfusion refractoriness (PTR), in which platelet counts do not increase after transfusion, occurs in many patients receiving platelet transfusions. PTR is a clinical condition that can harm patients. The causes of PTR can be divided into two types: immune and non-immune. Most cases of PTR are non-immune. Among immune causes, the most common is human leukocyte antigen (HLA) class I molecules. PTR caused by anti-HLA antibodies is usually managed by transfusing HLA-matched platelets. Therefore, it is important, especially for hemato-oncologists who frequently perform transfusion, to accurately diagnose whether the cause of platelet transfusion failure is alloimmune or non-immunological when determining the treatment direction for the patient. In this review, we discuss the definitions, causes, countermeasures, and prevention methods of PTR.

The Rh blood group system has C, D, E, c, and e as the main antigens, but ce(f) has been reported as a compound antigen. Anti-f(ce) is an unexpected antibody (Ab) against the ce(f) compound antigen. This paper reports a case with anti-f(ce) and anti-M Abs in a patient with liver cirrhosis. A 47-year-old male patient was repeatedly admitted to hospital due to recurrent hepatic encephalopathy. He showed disorientation and was admitted. A packed red blood cells (pRBCs) transfusion was required, and Ab identification test identified anti-f(ce) and anti-M Abs. Anti-f(ce) Ab can cause fetal neonatal hemolytic disease and a clinically serious hemolytic transfusion reaction (HTR), and anti-M Ab can cause a HTR when it reacts at 37℃. RBCs with Rh haplotype of CDe and negative for M antigen were transfused to the patient. There was no HTR. The possibility of an anti-f(ce) Ab was not considered when an unexpected Ab screening/identification test was performed. It was simply reported as an ‘unknown alloantibody’. Therefore, laboratory physicians should consider Abs to the Rh compound antigen when Abs to Rh antigens are identified, and efforts should be made to identify them to gain basic knowledge about Abs against Rh compound antigens.

Background: According to the revision of the Blood Management Act in 2020, medical institutions that meet certain conditions are obliged to install a transfusion management division in Korea. Therefore, this study assessed the management status of the transfusion management division at major medical institutions. Methods: From August 7th to August 18th, 2021, a survey questionnaire was given to laboratory physicians of 10 major medical institutions in Korea, and the installation and operation of the transfusion management division were surveyed. Results: The medical institutions that participated in this survey completed a transfusion management division in the first half of the year. Doctors, nurses, and medical technologists were assigned as medical personnel, and all laboratory physicians were leading the work as the head of the transfusion management division. Regarding the tasks performed at the transfusion management division, all medical institutions conducted a transfusion appropriateness assessment, education related to transfusion, and adverse transfusion reactions. Most medical institutions had difficulties because there was an insufficient basis to calculate the workforce and budget in installing and operating the transfusion management division. Conclusion There are rarely reference materials for the practice and operation of the transfusion management division, which has no precedent in Korea, so it is often difficult for medical institutions to prepare it. This study will be a reference for medical institutions that need to install a transfusion management division in the future.Efforts should be made to legislate transfusion management fees focused on the academic community.

PURPOSE: To investigate factors influencing the evaluation of background parenchymal enhancement (BPE) at follow-up breast magnetic resonance imaging (MRI) after adjuvant endocrine therapy. MATERIALS AND METHODS: One hundred twelve women with breast cancer and MRI of the contralateral unaffected breast before and after endocrine therapy were identified. Two readers in consensus performed blinded side-by-side comparison of BPE (minimal, mild, moderate, and marked) before and after therapy with categorical scales. Age, body mass index, menopausal status, treatment regimen (selective estrogen receptor modulator or aromatase inhibitor), chemotherapy, follow-up duration, BPE at baseline MRI, MRI field strength before and after therapy, and recurrence were analyzed for their influences on decreased BPE. RESULTS: Younger age, premenopausal status, treatment with selective estrogen receptor modulator, MRI field strength, and moderate or marked baseline BPE were significantly associated with decreased BPE. In multivariate analysis, MRI field strength and baseline BPE showed a significant association. CONCLUSION: MRI field strength and baseline BPE before and after therapy were associated with decreased BPE at post-therapy, follow-up MRI.

Sonography is an attractive supplement to mammography in breast cancer screening because it is relatively inexpensive, requires no contrast-medium injection, is well tolerated by patients, and is widely available for equipment as compared with MRI. Sonography has been especially valuable for women with mammographically dense breast because it has consistently been able to detect a substantial number of cancers at an early stage. Despite these findings, breast sonography has known limitations as a screening tool; operator-dependence, the shortage of skilled operators, the inability to detect microcalcifications, and substantially higher false-positive rates than mammography. Further study of screening sonography is still ongoing and is expected to help establish the role of screening sonography.
