BACKGROUND/AIMS: Transradial intervention (TRI) is becoming the preferred method over transfemoral intervention (TFI) because TRI is associated with lower incidence of major bleeding and vascular complications. However, there has been limited published data regarding the clinical outcomes of TRI versus TFI in Korean patients with ST-elevation myocardial infarction (STEMI). METHODS: A total of 689 consecutive STEMI patients who underwent primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) from January to December of 2009 at nine university hospitals were enrolled in this study. Mid-term angiographic and 12-month cumulative clinical outcomes of the TRI group (n = 220, 31.9%) were compared to those of the TFI group (n = 469, 28.1%). RESULTS: After propensity score matching, in-hospital complications and the 12-month major clinical outcomes during follow-up in the two groups were similar to each other. However, the incidence rates of repeat revascularization (6.4% vs. 0.5%, p = 0.003), target vessel revascularization (6.4% vs. 0.5%, p = 0.003), and major adverse cardiac events (MACE; 11.6% vs. 4.6%, p = 0.018) in the TFI group were higher than those in the TRI group during the 12-month of follow-up. CONCLUSIONS: In our study, TRI in STEMI patients undergoing primary PCI with DESs was associated with lower incidence of access site hematoma, 12-month repeat revascularization, and MACE compared to TFI. Therefore, TRI might play an important role in reducing bleeding complications while improving major clinical outcomes in STEMI patients undergoing primary PCI with DESs.

STUDY DESIGN: Literature review. OBJECTIVE: The aim of this article is to introduce the EOS imaging device, with a focus on spinal and pelvic alignment. SUMMARY OF LITERATURE REVIEW: The EOS imaging device can obtain images of spinal and pelvic alignment with almost no distortion, using a low radiation dose. MATERIALS AND METHODS: We searched for studies related to the use of EOS imaging device for spinal and pelvic alignment. RESULTS: The EOS is not only capable of simultaneously obtaining paired anteroposterior and lateral X-ray images with a low radiation dose, but also can reconstruct the image as if it was acquired in the patient's reference plane, limiting the distortion to the patient's thickness instead of the whole distance between the source and detector. The EOS device also has the advantage of accurately measuring the sagittal alignment of the spine and pelvis and the torsional deformity of the lower limbs, as the subject can be imaged while standing upright in a weight-bearing posture. CONCLUSIONS: EOS is a new diagnostic technique that can detect spinal and pelvic alignment and deformities of the lower limbs under weight-bearing conditions with a low radiation dose.

BACKGROUND: Rehabilitation of normal function and form is essential in cleft lip repair. In 2005, Dr. David M. Fisher introduced an innovative method, named “an anatomical subunit approximation technique” in unilateral cleft lip repair. According to this method, circumferential incision along the columella on cleft side of the medial flap is continued to the planned top of the Cupid's bow in straight manner, which runs parallel to the unaffected philtral ridge. Usually, small inlet incision is needed to lengthen the medial flap. On lateral flap, small triangle just above the cutaneous roll is used to prevent unesthetic shortening of upper lip. This allows better continuity of the Cupid’s bow and ideal distribution of tension. CASE PRESENTATION: As a modification to original method, orbicularis oris muscle overlapping suture is applied to make the elevated philtral ridge. Concomitant primary rhinoplasty also results in good esthetic outcome with symmetric nostrils and correction of alar web. As satisfactory results were obtained in three incomplete and one complete unilateral cleft lip patients, indicating Fisher’s method can be useful in cleft lip surgery with functional and esthetic outcome. CONCLUSIONS: Clinically applied Fisher's method in unilateral cleft lip patients proved the effectiveness in improving the esthetic results with good symmetry. This method also applied with primary rhinoplasty.

Human periodontal ligament stem cells (PDLSCs), a type of mesenchymal stem cell, are a promising source for dental regeneration and are identified in human periodontal ligaments from extracted third molars. Valproic acid (VPA) is a histone deacetylase inhibitor that has been used as a wide-spectrum antiepileptic drug and a medication for mood disorders. VPA has shown several effects on increasing the pluripotency of embryonic stem cells and controlling osteogenic differentiation, besides the prevention of seizures. However, its effect on proliferation and osteogenesis depends on the cell type and concentration. The aim of this study was to investigate the effects of cyclic and constant VPA treatment on PDLSCs. Proliferation and apoptosis of PDLSCs were determined with cyclic and constant VPA treatment. In cemento/ osteogenic differentiation, osteogenic markers decreased significantly after cyclic treatment with 0.5 mM VPA. In contrast, VPA enhanced osteogenic differentiation after constant treatment. With cyclic VPA treatment, p53 levels related to apoptotic pathway decreased to induce proliferation. These findings indicated that VPA has different roles in proliferation and differentiation of PDLSCs in vitro and in vivo via p53-related pathway.

BACKGROUND: Nicotine dependence and its severity are often determined by individuals’ psychosocial factors.This study purposed to analyze how Korean workers’ job stress is related with their nicotine dependence according to demographic and occupational characteristics in order to reduce smoking related to job stress and to establish objective indicators to be used in developing adequate smoking cessation strategies. METHODS: The subjects of this study were 4,639 workers who replied to the questionnaire survey. In addition, 1,948 current smokers were separated from non-smokers and ex-smokers, and the relationship between job stress and nicotine dependence was analyzed with the current smoker group. Nicotine dependence was tested using Fagerström’s Test of Nicotine Dependence, and stress was measured using a questionnaire on subjective stress felt by workers in their daily life and the short form of the Korean Occupational Stress Scale. RESULTS: The smoking rate was 54.1 % among men and 2.5 % among women. Nicotine dependence was significantly different according to interpersonal conflict, organization system and lack of reward (p < 0.05). As multivariate logistic analysis, job control, occupational climate and total stress score were statistical significant (p < 0.05). CONCLUSIONS: Job stress was found to be related with smoking status and nicotine dependence. Based on this result, it is suggested to enhance workers’ welfare for health promotion in workplace by improving their working environment in order to reduce job stress and consequently to decrease the smoking rate.

OBJECTIVE: Longstanding hypertension lead to left ventricular diastolic dysfunction with a development of a left atrial enlargement (LAE) which may result in vulnerability to atrial fibrillation (AF). Paroxysmal AF is usually unrevealed in the acute period of ischemic stroke, but is crucial for anticoagulation to prevent recurrent stroke. This study was aimed to investigate the frequency of LAE and the predictors of paroxysmal AF during the hospitalization of acute ischemic stroke. METHODS: A total 1,643 consecutive patients with acute ischemic stroke were registered in between January 2005 and December 2014. The subjects who had AF before index stroke or at admission were excluded. The clinical and echocardiographic findings of all patients were reviewed. Paroxysmal AF were detected on electrocardiography of Holter monitoring during hospitalization. LAE were defined as LA diameter larger than 44 mm in echocardiography. We compared the frequency of LAE between the patients with or without AF. Logistic regression analysis were performed to determine the echocardiographic parameters for prediction of paroxysmal AF. RESULTS: The mean age was 67.3 and the male was 55.6%. AF were detected in 123 (11.4%) of LAE(-) group but were detected in 102 (49.0%) in LAE(+) group. In logistic regression analysis, LAE significantly predicted for newly detected AF during hospitalization after adjusting covariates (odds ratio, 5.698; 95% confidence interval, 3.799-8.546; P<0.001). CONCLUSION: LAE was an independent predictor for AF during hospitalization in patients with acute ischemic stroke. Prolonged electrocardiography monitoring should be meticulously indicated for acute ischemic stroke with LAE to detect paroxysmal AF.

BACKGROUND: Plate fixation is the most commonly used technique for the treatment of shaft fractures of both forearm bones (SFBFBs). However, all fractures are difficult to treat with plate fixation because of soft tissue injuries, fracture patterns, or the patient's condition. The purpose of this study is to compare the functional results of plate fixation only and combined plate and intramedullary (IM) nail fixation in SFBFBs. METHODS: Fifty-nine cases of SFBFBs that were surgically treated from June 2007 to July 2012 were retrospectively reviewed. In this study, 47 cases that were followed up for more than 12 months were included. All SFBFBs were divided into two groups according to the methods used for internal fixation: plate fixation only (group A) and combined plate and IM nail fixation (group B). The fixation methods were determined intraoperatively. Plate fixation was considered as the first option in all cases, but combined plate and IM nail fixation was selected as the second option if it was difficult to be fixed with plate only. Groups A and B comprised of 31 and 16 cases, respectively. The functional results were evaluated by the Grace and Eversmann rating system and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS: In groups A and B, a radiologic union was achieved in 30/31 and 14/16 cases and average union time was 11.1 and 17.8 weeks, respectively. According to the Grace and Eversmann rating system, group A had excellent results in 15 cases, good in 14, acceptable in one, and unacceptable in one. Group B had excellent results in three cases, good in nine, acceptable in two, and unacceptable in two. The average DASH score was 7.1 points (range, 0 to 19.2 points) in group A and 15.1 points (range, 0 to 29.6 points) in group B. Three cases of nonunion with unacceptable results achieved a bony union by additional procedures and the functional results of these cases improved to good or excellent. CONCLUSIONS: The functional results and the average union time were superior in group A than in group B. However, we think that combined fixation is a useful method for SFBFBs that cannot be treated with plate fixation only.

Drug-induced liver injury (DILI) is an increasingly common cause of acute hepatitis. We examined clinical features and types of liver injury of 65 affected patients who underwent liver biopsy according DILI etiology. The major causes of DILI were the use of herbal medications (43.2%), prescribed medications (21.6%), and traditional therapeutic preparations and dietary supplements (35%). DILI from herbal medications, traditional therapeutic preparations, and dietary supplements was associated with higher elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels than was DILI from prescription medications. The types of liver injury based on the R ratio were hepatocellular (67.7%), mixed (10.8%), and cholestatic (21.5%). Herbal medications and traditional therapeutic preparations were more commonly associated with hepatocellular liver injury than were prescription medications (P = 0.002). Herbal medications and traditional therapeutic preparations induce more hepatocellular DILI and increased elevations in AST and ALT than prescribed medications.

A 49-year-old woman visited our hospital with dysphagia and chest pain. In another hospital, she was diagnosed as reflux esophagitis. Although she had taken proton pump inhibitor and prokinetics drugs for a long time, she was not relieved of any symptoms. On the basis of high resolution manometry and endoscopic ultrasonography findings, Jackhammer esophagus was diagnosed. In this patient, peroral endoscopic myotomy (POEM) was performed for long myotomy of thickened circular muscle. During the procedure, there were no significant complications and she was discharged uneventfully. Symptoms were completely improved during three months after POEM. Here, we report on a case of Jackhammer esophagus treated by POEM.
