ABSTRACT
OBJECTIVE: The aim of this study was to describe the clinical characteristics of acute hemorrhagic rectal ulcer (AHRU) and to elucidate its predictive factors. METHODS: The medical records of patients with AHRU were retrospectively reviewed. Their baseline clinical characteristics were compared with those of patients with non-AHRU lower gastrointestinal bleeding to identify predictive factors for AHRU. RESULTS: Among the 118 patients who underwent emergency endoscopy due to acute massive hematochezia from 2013 to 2015, 25 (21.2%) were diagnosed as having AHRU. Of them, 22 (88.0%) were successfully managed endoscopically and 3 (12.0%) underwent surgery. Six (24.0%) patients developed rebleeding within 1-9 days after the initial bleeding, which was controlled by a repeat endoscopy. Five (20.0%) died during follow-up. A multivariate-adjusted logistic regression analysis revealed that a lower serum albumin level, worse Eastern Cooperative Oncology Group (ECOG) performance status and history of constipation were significant factors for predicting AHRU. Hypoalbuminemia (<30 g/L) had a sensitivity, specificity and positive and negative predictive values of 84.0%, 78.5%, 51.2% and 94.8% for predicting AHRU, respectively. CONCLUSIONS: Approximately 20% of patients with massive hematochezia had AHRU. Most patients with AHRU can be managed endoscopically. Low serum albumin level, poor ECOG performance status and prior constipation could be used in distinguishing patients with and without AHRU, facilitating the selection of optimal bowel preparation method for massive hematochezia.

Myxoma of the aortic valve is an exceedingly uncommon condition. In this article, we report the case of a 72-year-old man with myxoma arising from the aortic valve. We extirpated the mass and repaired the aortic valve with the patient under cardiopulmonary bypass. The postoperative course was uneventful. Histological examination confirmed that the mass was a myxoma.
ABSTRACT
A coronary aneurysm (CA) can occur in sirolimus-eluting stent (SES)-implanted coronary lesions. Although several possible mechanisms have been suggested, the precise pathogenesis of a CA in SES-implanted lesions is still unknown. We report a patient with Churg-Strauss syndrome who underwent successful percutaneous coronary intervention with SES and then experienced a CA in an SES-implanted coronary lesion. We describe the CA characteristics through the use of coronary angiography, coronary 64-multidetector computed tomography, and intravascular ultrasound and discuss the etiological factors for the CA in this patient.
ABSTRACT
Splenic infarction is most commonly caused by cardiovascular thromboembolism; however, splenic infarction can also occur in hematologic diseases, including sickle cell disease, hereditary spherocytosis, chronic myeloproliferative disease, leukemia, and lymphoma. Although 10% of splenic infarction is caused by hematologic diseases, it seldom accompanies autoimmune hemolytic anemia (AIHA). We report a case of a 47-year-old woman with iron deficiency anemia who presented with pain in the left upper abdominal quadrant, and was diagnosed with AIHA and splenic infarction. Protein C activity and antigen decreased to 44.0% (60-140%) and 42.0% (65-140%), respectively. Laboratory testing confirmed no clinical cause for protein C deficiency, such as disseminated intravascular coagulation, sepsis, hepatic dysfunction, or acute respiratory distress syndrome. Protein C deficiency with splenic infarction has been reported in patients with viral infection, hereditary spherocytosis, and leukemia. This is a rare case of splenic infarction and transient protein C deficiency in a patient with AIHA.
ABSTRACT
A 55-year-old man with massive pulmonary thromboembolism underwent thrombolysis, pulmonary artery embolectomy and tricuspid annuloplasty. Nine months later, a mobile echogenic intra-cardiac mass was found in the tricuspid valve. Because the patient had undergone annuloplasty, thrombosis was suspected as the most likely diagnosis and thrombolytic therapy was instituted. However, the size of the cardiac mass did not change and after surgical excision the mass was found to be a myxoma. Cardiac valvular tumors are uncommon and when they occur they are usually slow growing fibroelastomas. In this case, the rapid growing cardiac myxoma on the tricuspid valve was found after the occurrence of pulmonary thromboembolism. To our knowledge, this is first reported case of tricuspid valve myxoma in Korea.
