ABO-incompatible solid organ transplantation (ABOi TPL) is a widely accepted treatment option for treating end-stage renal or liver diseases. Although the appropriate selection of the ABO blood group for transfusion is a key step for successful ABOi TPL, there are no evidence-based guidelines to cope with this issue. In this letter, we suggest appropriate blood selection criteria for ABOi TPL based on the basic principles of ABO incompatibility. For major mismatched ABOi TPL, red blood cells (RBCs) should be of the organ recipient’s ABO group, while platelets (PLTs) and plasma products should be of the donor’s ABO group. For the bidirectional mismatched cases, it is desirable to select recipient type RBCs and group AB PLTs and plasma products.

The unexpected antibody screening test is one of the most important pretransfusion tests. The tests are usually performed using commercial cells, which in Asia may not include clinically important antigens. To overcome this limitation, some laboratories use additional screening cells, including Di a or Mi a . However, these efforts are not supported by the Korean National Health Insurance system. The estimated total medical costs for using additional screening cells are less than the estimated total medical costs for the management of potential hemolytic transfusion reactions caused by missing clinically important antibodies. Hence, it is recommended that the Health Insurance system should be modified to take this into account and address the issue.

Acute peripheral vestibulopathy, of which the chief complaint is positional vertigo, comprises benign paroxysmal positional vertigo (BPPV), labyrinthitis, labyrinthine fistula, and cerebellopontine angle tumors. Since the typical presentation of labyrinthine fistulas may be sensorineural hearing loss, positional vertigo, or disequilibrium, it is often difficult to distinguish from BPPV or Meniere's disease. Herein we report a 61-year-old female patient with typical symptoms and signs attributable to geotropic type variant of the lateral semicircular canal BPPV on the left side, who eventually was confirmed as having a labyrinthine fistula from chronic otitis media with cholesteatoma on the left side. This is another case where, even in the presence of isolated vertigo showing typical findings of acute peripheral vestibulopathy, other otologic symptoms and signs must not be overlooked.

A 42 year-old male with a history of multidrug-resistant pulmonary tuberculosis suddenly developed massive hemoptysis. Embolization of a bronchial artery branch and the collateral systemic arteries did not resolve the recurrent bleeding. Spiral computerized tomography(spiral CT) of the chest showed contrast enhanced nodules within a large cavity at the left lower lobe in the arterial phase suggesting a Rasmussen aneurysm. A pulmonary angiogram showed abnormal vascular nodules at that site. Coils were deployed at both the proximal and distal vessels of this aneurysmal sac for embolization. Transcatheter arterial embolization is a safe and effective means of controlling bleeding from this pulmonary arterial pseudoaneurysm. Here we report a case of a Rasmussen aneurysm diagnosed by spiral CT, which was successfully treated by pulmonary arterial embolization with a coil.

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.

Familial pseudohyperkalemia (FP) is a dominantly inherited condition caused by variants in the gene ABCB6 resulting in red blood cell (RBC) membrane protein defects. FP is generally asymptomatic. However, FP RBCs have an increased permeability to monovalent cations when stored below 37°C. Transfusion of RBC components donated by FP individuals can induce hyperkalemia and may be causally related to transfusion-associated hyperkalemic cardiac arrest, particularly in neonates and infants. Therefore it is necessary to accurately evaluate the frequency of FP occurrence in the Korean population and assess whether FP RBCs have significantly higher supernatant potassium levels. Efforts should be made to recognize the effects of blood products collected from FP donors on blood transfusion recipients to reduce the risk of hyperkalemia, especially in fetuses, infants, and patients at risk of this condition.

ABO/RhD-mismatch transfusions are frequently encountered in clinical practice, so a systematic and thorough understanding of these events is necessary. In the case of ABO minor-incompatible transfusions, it is important to consider the possibility of hemolytic transfusion reactions because of the reaction between the ABO antibodies in the blood product and the patient’s red blood cells. For platelet products, the risk is approximately 1 in 9,000.In ABO major-incompatible transfusions, red blood cell products are contraindicated, but plasma or platelet products may be allowed in situations such as blood product shortages. In RhD major-incompatible transfusions, the use of Rh immunoglobulin to prevent alloimmunization may be considered depending on the patient’s clinical status and the availability of blood products. In the case of RhD major-incompatible red blood cell transfusions, however, such prevention is difficult to apply in Korea. ABO/RhD-mismatch transfusion may also affect the long-term outcomes of patients, in addition to immediate hemolytic transfusion reactions. Therefore, decisions must be made based on the patient’s clinical situation considering the benefits and potential risks.
