Catecholamine-induced cardiomyopathy associated with neuroblastoma is rarely reported. We report a case of catecholamine-induced cardiomyopathy associated with neuroblastoma in a 33-month-old female that was treated with extracorporeal membrane oxygenation (ECMO). She was tentatively diagnosed with acute myocarditis and presented with hypertension. Because of rapid patient deterioration despite pharmacological treatments, ECMO was applied. ECMO can be helpful in cases of catecholamine-induced cardiomyopathy associated with neuroblastoma.

In children and young adults, secondary epiretinal membranes after ocular trauma, pars planitis, ocular toxocariasis, and Coat's disease are common and spontaneous separation occurs in a relatively higher rate with improvement in visual acuity than elderly patients. In a 31-year-old man with pars planitis, diffuse epiretinal membrane in the macula became thinner during systemic and topical steroid therapy. Two years after treatment, the preretinal membrane spontaneously separated from the macula to the inferior temporal arcade, and visual acuity improved from 0.15 to 1.0. The authors reviewed the available literatures regarding the possible mechanisms for the spontaneous separation ofepiretinal membrane.

OBJECTIVE: The purpose of this study is to investigate the incidence of new compression and to analyze factors that influence the fractures in adjacent levels after percutaneous vertebroplasty (PVP). METHODS: This retrospective study examined 206 patients who had undergone PVP for single level osteoporotic or osteopenic compression fractures during the last seven years in our department. After PVP, the patients were observed for at least over one year, and 29 patients showed new additional compression fractures in adjacent levels. One hundred seventy seven patients who did not show additional compression fractures were analyzed as the control group. Statistical comparisons were performed between the groups, in terms of age, gender, bone mineral density, whether bisphosphonate (BPP) was treated, preoperative kyphosis, preoperative wedge angle, change in wedge angle, amount of bone cement, existence of intradiscal bone cement leakage, and initial fracture levels. RESULTS: The statistically significant factors that influence new compression fractures in adjacent levels after PVP were as follows: being female, initial thoracolumbar junction fracture, preoperative large kyphotic, preoperative large wedge angle, change in wedge angle, administration of BPP in osteopenia group, and intradiscal cement leakage. CONCLUSION: This study identified many factors that influence newly developed compression fractures in adjacent levels after PVP. Interestingly, the administration of BPP in osteopenia group had positive influence on new fractures in this study. Therefore, we recommend early administration of BPP to patients with osteopenia.

Bacterial endophthalmitis is a very difficult ophthalmic disease to treat because of the consistently poor results with conventional therapy. lntravitreal injection of antibiotics is increasingly gaining the acceptance as a method of producing high vitreal concentrations that may be useful in the treatment of bacterial endophthalmitis. The author performed this experiment to determine the clerance rare of intravitreal gentamicin in the rabbit eyes. We observed the clearance of gentamicin in phakic and aphakic rabbit eyes into which 20 micro gram/0.1 ml of gentamicin was injected. In phakic eyes, about 52% of gentamicin was cleared at 24 hours after injection. In aphakic eyes with intact posterior capsule, 64% of gentamicin was cleared at 24 hours after injection. In aphakic eyes with incised posterior capsule, the clearance rate at 24 hours after injection was about 70%. Intravitreal gentamicin was cleared more rapidly from the aphakic eyes than from that of phakic eyes.

We experienced a case of thoracic aortic aneurysm combined with coronary artery disease. A 68-year-old man complained of anginal pain in the left anterior chest and nonspecific pain in the posterior chest. The aneurysm was extending from left subclavian artery to the diaphragm and sign of impending rupture was noted in the chest CT. Coronary angiograms revealed significant obstruction of left circumflex coronary artery(>95%) and left anterior descending artery(>50%). Exposure was obtained through the left posterolateral thoracotomy incision in the 4th intercostal space and then partial femoro-femoral cardio- pulmonary bypass was established. After aortic cross clamping, the aneurysmal sac was opened and repaired with interposition of 26 mm Hemashield graft. Under the beating heart with femoro-femoral cardiopulmonary bypass, aorto-left circumflex coronary bypass with autogenous saphenous vein used as conduit was performed. Postoperatively multiple cerebral infarction ensued due to intraoperative hypovolemic shock and hypoxic brain damage during cardiopulmonary bypass. Currently, the patient's mental status is drowsy and in an improving state.

Subclavian artery occlusion after blunt trauma is an extremely rare injury. This has been attributed to its wellprotected location deep in the scalene triangle, bounded by the first rib and clavicle. A case of post-traumatic occlusion of the subclavian artery with clavicle fracture was reported by Sodhi et al in 2006 and in Korea was reported by Han et al in 2001. We believe that is the first report of post-traumatic occlusion of the subclavian artery without clavicle and first rib fracture in Korea.

Oseltamivir has been used as a worldwide preparation for treatment of influenza A and B including H1N1. Gastrointestinal discomforts as like nausea, vomiting are commonly reported but acute hemorrhagic colitis is a very rare adverse effect. We report a case of a 17-year-old male who showed abdominal pain, diarrhea and hematochezia after the second administration of oseltamivir. Computed tomography revealed continuous, circumferential and edematous wall thickening involving ascending to descending colon with pericolic infiltration. Colonoscopic examination revealed diffuse mucosal edema, congestion and friability, suggesting hemorrhagic colitis. Histopathological examination showed ischemia and focal loss of the crypts. It also showed hyalinization and minimal inflammatory cell infiltration in the lamina propria, consistent with acute to subacute ischemic colitis. This report is the first case of oseltamivir-related ischemic colitis proved by both endoscopic examination and pathologic findings in the patient who had no risk factor of ischemic colitis in Korea.

From May 1, 1993 to May 31 1995, the authers studied retrospectively 211 patients who underwent cardiovascular operation with cardiopulmonary bypass (CPB). Because we were interested in new development of ARF (prevalence, mortality rate, and main risk factors), we performed a multivariate statistical analysis about data of patients with preoperative serum creatinine values of less than 1.5 mg/dL. Normal renal function before operation (serum creatinine level less than 1.5 mg/dL) was registered in 198 (74%) patients. Of these, 27 (14%) patients showed postoperative renal complication, including 20 (10%) patients classified as renal dysfunction (serum creatinine level between 1.5 and 2.5 mg/dL) and 7 (4%) patients as acute renal failure (serum creatinine level higher than 2.5 mg/dL). The mortality rate was 5.8% in normal patients, 5% in patients with renal dysfunction, and 43% when acute renal failure developed (p=0.036). Indeed, the renal impairment proved to be an independent predictor of mortality (odd ratio 2.52~11.25), along with cardiovascular (odd ratio 4.20) and respiratory (odd ratio 2.18) complications. Multivariate analysis identified the following variables as independent risk factors for postoperative renal impairment : advanced age (odd ratio 1), need for emergency operation (odd ratio 3.78), low-output syndrome (odd ratio 3.66), respiratory complication (odd ratio 1.30), need for deep hypothermic circulatory arrest (odd ratio 1.4). The 13 patients (7%) with preoperative renal failure showed a significantly higher morbidity and mortality rate than those without renal complications before operation. We concluded that the likelihood of severe renal complications is resonably low in the patients undergoing cardiac operation without preexisting renal dysfunction, but associated mortality remains high. A prominant role of hemodynamic factor in the development of postoperative acute renal failure must be recognized during preoperative, intraoperative, and postoperative periods.
