Pediatric around Elbow Fracture

This study assessed the current concepts of pediatric elbow fractures. PubMed and Embase databases were searched for publications in English on elbow fractures. Papers believed to yield significant findings to this area were included in this review. The supracondyle of humerus, lateral condyle of the humerus, proximal radius, and proximal ulna fractures were included. Sixteen papers and textbooks were selected. Pediatric elbow fractures should be evaluated for combined injuries. Treatment should be done accurately for each fracture for the further growth of children.

Aggravation of Hepatopulmonary Syndrome after Sildenafil Treatment in a Patient with Coexisting Portopulmonary Hypertension

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPHTN) are complications of portal hypertension and cirrhosis. Their pathophysiological mechanisms clearly differ. HPS is characterized by a defect in arterial oxygenation induced by pulmonary vascular dilatation. In contrast, PPHTN is predominantly due to excessive pulmonary vasoconstriction and vascular remodeling, but is rarely associated with hypoxia. We report a case of a patient who had both HPS and PPHTN at the time of presentation. HPS was aggravated after sildenafil administration for the treatment of PPHTN. We demonstrated increased amount of intrapulmonay shunt after sildenafil challenge by using agitated saline contrast transthoracic echocardiography.

Trans-Radial versus Trans-Femoral Intervention for the Treatment of Coronary Bifurcations: Results from Coronary Bifurcation Stenting Registry

Trans-radial (TR) approach is increasingly recognized as an alternative to the routine use of trans-femoral (TF) approach. However, there are limited data comparing the outcomes of these two approaches for the treatment of coronary bifurcation lesions. We evaluated outcomes of TR and TF percutaneous coronary interventions (PCI) in this complex lesion. Procedural outcomes and clinical events were compared in 1,668 patients who underwent PCI for non-left main bifurcation lesions, according to the vascular approach, either TR (n = 503) or TF (n = 1,165). The primary outcome was major adverse cardiac events (MACE), including cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR) in all patients and in 424 propensity-score matched pairs of patients. There were no significant differences between TR and TF approaches for procedural success in the main vessel (99.6% vs 98.6%, P = 0.08) and side branches (62.6% vs 66.7%, P = 0.11). Over a mean follow-up of 22 months, cardiac death or MI (1.8% vs 2.2%, P = 0.45), TLR (4.0% vs 5.2%, P = 0.22), and MACE (5.2% vs 7.0%, P = 0.11) did not significantly differ between TR and TF groups, respectively. These results were consistent after propensity score-matched analysis. In conclusion, TR PCI is a feasible alternative approach to conventional TF approaches for bifurcation PCI (clinicaltrials.gov number: NCT00851526).

A Case of Purulent Pericarditis Complicated by Klebsiella pneumoniae Sepsis - A Case Report - / 대한구급학회지

Although the incidence of purulent pericarditis has decreased significantly in the modern antibiotic era, purulent pericarditis remains a life-threatening disease. Therefore, a high index of clinical suspicion should be maintained to diagnose this life-threatening illness at an early stage. We report an extraordinary case of purulent pericarditis, caused by Klebsiella pneumoniae bacteremia, which developed during the recovery of septic shock with urinary tract infection. Despite of early diagnosis and pericardial drainage, in addition to adequate antibiotics, the patient subsequently developed multiple organ failure leading to death. The case highlights that purulent pericarditis is a rare yet possible disorder complicated from septic shock with bacteremia in the antibiotic era. Therefore, purulent pericarditis should always be considered as a possible complication, especially in patients with K. pneumoniae bacteremia and progressive cardiomegaly.

Electromagnetic Interference of Wireless Local Area Network on Electrocardiogram Monitoring System: A Case Report

Electromagnetic interference (EMI) can affect various medical devices. Herein, we report the case of EMI from wireless local area network (WLAN) on an electrocardiogram (ECG) monitoring system. A patient who had a prior myocardial infarction participated in the cardiac rehabilitation program in the sports medicine center of our hospital under the wireless ECG monitoring system. After WLAN was installed, wireless ECG monitoring system failed to show a proper ECG signal. ECG signal was distorted when WLAN was turned on, but it was normalized after turning off the WLAN.

A Case of Crescentic Glomerulonephritis Superimposed on Membranous Glomerulopathy / 대한신장학회지

Membranous glomerulopathy (MGN) is a common cause of nephrotic syndrome in adults. Renal failure gradually develops in patients with MGN and crescentic glomerulonephritis (CGN) superimposed on MGN is a rare cause of acute renal failure. In most cases patients showed nephrotic syndrome with acute renal failure. We report a 33-year-old woman with azotemia but with no other symptoms such as nephrotic syndrome she had been diagnosed to have MGN 15 months before. There seemed to be no other cause of azotemia. Renal biopsy was performed and revealed CGN on existing MGN. She was treated with immunosuppression treatment and azotemia was improved. When unexplained azotemia develops in patients with MGN, we should promptly investigate superimposed conditions including CGN. In CGN superimposed on MN, a potentially reversible condition with appropriate immunosuppression therapy should be considered.
