A 52-year-old woman presented with atypical chest pain. Coronary angiography demonstrated multiple microfistulae between left coronary artery and left ventricle (LV) cavity, extensive enough to produce an LV angiogram. This LV angiogram revealed apical hypertrophic cardiomyopathy (HCM) which was confirmed by echocardiography. Coronary steal phenomenon by coronary artery microfistulae and HCM might have a role for developing of angina in patient with apical HCM.

Herbal remedies and health foods are widely used, and their side effects have been reported. Glucosamine is a naturally occurring amino-monosaccharide and a safe health food; rarely, however, it can cause cholestatic and hepatocellular hepatitis. We describe a case of drug-induced autoimmune hepatitis after ingestion of glucosamine. A middle-aged woman who had no history of liver disease complained of jaundice after taking glucosamine. The diagnosis of drug-induced acute autoimmune hepatitis was made using the Roussel Uclaf Causality Assessment Method score based on the patient's history and laboratory data, and percutaneous liver biopsy. After supportive care and administering prednisolone and azathiprine, the patient showed rapid improvement in clinical symptoms and laboratory findings.

Superior mesenteric artery (SMA) syndrome is an uncommon disease that results from SMA compression of the third portion of the duodenum. Patients with SMA syndrome present with upper gastrointestinal symptoms, such as nausea, vomiting, and abdominal pain. The diagnosis is usually made from an upper barium study or computed tomography. Typically, SMA syndrome is caused by a decreased aortomesenteric angle of 6degrees to 25degrees. An underweight body mass index (BMI) is a risk factor for development of SMA syndrome. There are few reports of the role of linear endoscopic ultrasound (EUS) in the diagnosis of SMA syndrome. We report a case of SMA syndrome, with normal BMI, that was diagnosed with the aid of linear EUS. Although SMA syndrome is not typically within the scope of practice of endosonographers, it is useful to get familiar with the findings.

BACKGROUND/AIMS: While surgical resection remains the standard of care in the treatment of upper urinary tract malignancies, nephrectomy is a risk factor for the development of chronic kidney disease (CKD). The aim of this study was to determine whether histologic evaluation of non-neoplastic kidney could enable early identification of unrecognized kidney disease and could be of prognostic value in predicting postoperative renal outcomes. METHODS: We retrospectively analyzed 51 patients with upper urinary tract malignancies who received uninephrectomy or uninephroureterectomy. A thorough pathologic evaluation of non-neoplastic kidney including special stains, immunofluorescence, and electron microscopic studies was performed. The degree of parenchymal changes was graded from 0 to 15. RESULTS: Of 51 patients, only 13 showed normal kidney pathology. Fifteen patients showed glomerular abnormalities, 14 showed diabetic nephropathy, and 11 showed vascular nephropathy. There was one case each of reflux nephropathy and chronic pyelonephritis. The median histologic score was 5 points. Only 25.4% of patients had ≤ 3 points. Score more than 5 was observed in 47.1% of patients. Postoperative estimated glomerular filtration rate (eGFR) at 3 to 36 months were obtained from 90.2% of patients, and of those, 34.8% had de novo CKD. Since no one had CKD in partial nephrectomized patients, we determined risk factors for CKD in radical nephrectomized patients. Cox regression analysis revealed that postoperative AKI, preoperative eGFR, and histologic score of non-neoplastic kidney were the independent predictors for CKD. CONCLUSIONS: We conclude that routine pathologic evaluation of non-neoplastic kidney provides valuable diagnostic and prognostic information.

BACKGROUND: Although effective antifungal agents for the treatment of candidemia have recently been introduced, the mortality rate attributed to candidemia remains high (19~49%). OBJECTIVE: This study aimed at evaluating the risk factors for mortality in patients with candidemia and at assessing the usefulness of a Candida Score in these patients. METHODS: A cohort of patients with positive blood cultures for Candida species was retrospectively analyzed at Soonchunhyang University Hospital, a 750-bed teaching hospital, from May 2003 to February 2012. The Candida Score was calculated by assigning 1 point to any of total parenteral nutrition (TPN), surgery, or multifocal Candida species colonization, and 2 points to severe sepsis. RESULTS: Sixty patients (68.3% men; mean age (standard deviation [SD]), 61.8 [18.9] years) with blood cultures positive for Candida species were identified. Most patients had been admitted to an intensive care unit (48 [80%]), were receiving broad-spectrum antibiotics (37 [61.7%]), had TPN (29 [48.3%]), had diabetes mellitus (23 [38.3%]), and were receiving hemodialysis (10 [16.7%]). The mean (SD) Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 19.60 (8.8). Twenty-three patients (38.3%) had a Candida Score >2.5. The Candida species causing infection included C. albicans (41 [68.3%]), C. tropicalis (7 [11.7%]), C. parapsilosis (4 [6.7%]), C. krusei (3 [5%]), C. glabrata (3 [5%]), C. guilliermondii (1 [1.7%]), and C. catenulata (1 [1.7%]). Only 32 patients (53.3%) received adequate antifungal treatment. The candidemia-related mortality rate was 61.7% (n = 37 patients). Multivariate logistic regression analysis demonstrated that a high APACHE II score (adjusted odds ratio [aOR], 1.2; 95% confidence interval [95% CI], 1.0~1.3; p = 0.01), presence of a malignancy (aOR, 14.8; 95% CI, 2.5~88.0; p = 0.003), and treatment with an antifungal agent (aOR, 0.2; 95% CI, 0.0~1.0; p = 0.048) were associated with disease-related mortality. CONCLUSION: The risk factors for mortality in patients with candidemia are a high APACHE II scores and presence of a malignancy. However, the sensitivity of the Candida Score was not high (38.3%). New methods to rapidly identify candidemia and avoid delays in treatment with appropriate antifungal therapy are needed.

Microvascular thrombosis is an uncommon pathological finding in deceased donor kidneys. It is associated with disseminated intravascular coagulation (DIC) after brain injury in the donor. Although DIC in deceased kidney donors is known to have no association with graft outcome, microvascular thrombosis with DIC in a donor can cause renal graft impairment. For this reason, some transplantation centers do not accept these kidneys. A 39-year-old female donor had a subarachnoid hemorrhage. After a short period of cardiopulmonary resuscitation, we applied extracorporeal membrane oxygenation to maintain hemodynamic stability. The laboratory data were consistent with DIC. The recipient was a 38-year-old male patient who had been undergoing hemodialysis for 7 years because of end-stage renal disease of unknown cause. Zero-time graft biopsy revealed multiple intraluminal fibrin thrombi without peritubular capillaritis. Delayed graft function occurred after transplantation, and hemodialysis was started. Graft renal biopsy was performed on the third day after transplantation. The percentage of intraglomerular fibrin thrombi had decreased, and no significant peritubular capillaritis or C4d staining was observed. The function of the transplanted kidney started to recover, and hemodialysis was discontinued on the 10th day after surgery without specific treatment. Follow-up biopsy performed 20 days after the transplantation revealed normal kidney with completely resolved fibrin thrombi. We report herein a case of microvascular thrombosis in renal allograft from a DIC donor.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder that leads to mucocutaneous telangiectasias, epistaxis, and gastrointestinal bleeding. Depending on the severity and manifestation of the disease, various therapeutic modalities have been used, from local bleeding control to surgery or concomitant drug therapy. Several articles under review have presented guidelines for treatment of HHT with bevacizumab as a direct anti-angiogenesis strategy. Still, neither the exact optimal dose nor the minimum effective dose of intravenous bevacizumab in patients with severe HHT has been reported. A 55-year-old man presented with long-standing epistaxis, recent melena, dizziness, and a three-generation family history of chronic epistaxis, anemia, and regular blood transfusions. Treatment with argon plasma coagulation (APC) for the gastrointestinal bleeding failed to raise hemoglobin levels, we considered using the bevacizumab. We report a patient with severe HHT, who was treated with low-dose bevacizumab (2 mg/kg) and improved substantially.
