BACKGROUND AND OBJECTIVES: One of problems for the management of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) is the difficulty of determining the affected ear using Ewald's second law. The purpose of this study is to develop the new "Bow and Lean Test (BLT)" to determine easily the affected ear of HSC-BPPV and evaluate its efficiency. MATERIALS AND METHOD: We compared the efficiency between the classical method and BLT in 26 patients with HSC-BPPV. The classical method is based on Ewald??s second law comparing the intensity of nystagmus or symptoms in head roll test. BLT is based on the direction of both "bowing nystagmus" and "leaning nystagmus" at head's bowing and leaning state on sitting position. The affected ear is the same direction of bowing nystagmus in canalolithiasis and the same direction of leaning nystagmus in cupulolithiasis. RESULTS: In 26 patents (15 canalolithiasis, 11 cupulolithiasis), 3 (11.5%) patients did not show a prominent affected ear in the classical method, and 7 (26.9%) patients showed the different affected ear between two methods. All 10 patients were successfully treated with just one trial of barbecue rotation based on the affected ear in BLT. Three patients did not show any bowing or leaning nystagmus. The side with canal paresis in all 4 patients, who showed significant canal paresis in bithermal caloric tests, was equal to the affected ear based on BLT. CONCLUSION: "Bow and Lean Test" (also called "Choung's test") is a new method which can easily determine the affected ear of HC-BPPV.

Background: The incidence of inappropriate shocks remains high at 30% in patients with implantable cardioverter-defibrillators (ICDs). This retrospective study sought to examine the efficacy of strategic programming (ICD programming with a long detection interval and high-rate cutoff) in reducing electrical storm, inappropriate shocks, and unexpected hospital visits in patients with ICDs with/without cardiac resynchronization therapy with defibrillator (CRT-Ds). Methods: This was a single tertiary center retrospective study, evaluating the clinical outcomes, especially regarding inappropriate therapies in patients with ICDs or CRT-Ds. Enrolled patients underwent ICD or CRT-D implantations from January 2008 to May 2016. Clinical information was attained by a thorough chart review. Results: We analyzed 155 defibrillator patients from January 2008 to May 2016 (124 patients had ICDs and 31 had CRT-Ds). Since we adopted this strategic programming as a default programming from 2015 implanted ICDs and CRT-Ds, we divided the patients into two groups: devices implanted before 2015 (group A, n = 94) versus implanted after 2015 (group B, n = 61). During a median of 1289 days of follow-up, electrical storms occurred in three patients (eight events) in group B versus 11 (28 events) in group A (P = 0.18); appropriate therapies were delivered in 27 patients (56 events) in group A versus 7 (15 events) in group B (P = 0.72); inappropriate therapies were delivered in 15 patients (21 events) in group A versus 1 with 1 episode in group B (P = 0.03); and 5 unexpected hospitalizations occurred in four patients in group B versus 36 in 24 patients in group A (P = 0.02). Conclusion The clinical application of strategic programming reduced inappropriate shocks and unexpected hospitalizations in ICD and CRT-D patients.

BACKGROUND: Corticosteroids and intravenous immunoglobulin (IV-Ig) have been used asfirst line treatments for acute idiopathic thrombocytopenic purpura (AITP) in children. High dose dexamethasone (HD) has been reported to be effective for chronic refractory ITP and for the initial treatment of AITP in adults. There has been no report about HD as the initial treatment for childhood AITP. We assessed the effectiveness of HD for the initial treatment of childhood AITP, as compared to IV-Ig. METHODS: 25 Patients with newly diagnosed AITP were enrolled. We conducted a prospective, randomized study to compare the two treatment options. 11 patients were treated with IV-Ig and 14 patients were treated with HD. The platelet counts were assessed at 3, 5, 7, 14 and 21 days after the beginning of the treatment. The adverse effects were noted, and the patients were followed for more than 6 months. RESULTS: Both the IV-Ig and HD groups showed a rapid rise of the platelet counts and the platelet counts were maintained at 3, 5, 7, 14 and 21 days. The difference of platelet counts between the two groups was significant at day 5 (P<0.05). During the follow-up period, 5 patients had a recurrence: 2 in IV-Ig group and 3 in HD group. All 5 patients were re-treated with HD and they had a good response. One of the recurred patients in the IV-Ig group had chronic ITP. Some side effects were observed, but they were not severe enough to necessitate the discontinuation of treatment. CONCLUSION: We conclude that HD is as effective and safe as high dose IV-Ig for the initial treatment of childhood AITP. The choice between these treatment options can be made according to the cost-effectiveness and the therapy-related risks.

PURPOSE: Early identification of iron deficiency in young children is essential to prevent damaging long-term consequences. It is often difficult for the pediatrician to know which indices should be used when diagnosing these conditions especially in hospitalized young children. This study investigated the clinical significances of reticulocyte hemoglobin content in young children with acute infection. METHODS: We studied 69 young children aged from 6 to 24 months admitted with acute infection in a single center. Venous blood was drawn to determine hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), hemoglobin content (CH), reticulocyte hemoglobin content (CHr), and red blood cell distribution width (RDW) using ADVIA 120 (Bayer Diagnostics, NY, USA). For evaluating iron status, iron, total iron binding capacity, ferritin and transferrin saturation (Tfsat) were determined. Iron deficiency was defined as Tfsat less than 20%, and iron deficiency anemia as Tfsat less than 20% and Hb level less than 11 g/dL. RESULTS: In all, 47 were iron deficient; 17 of these had iron deficiency anemia. CHr was the only significant predictor of iron deficiency (likelihood ratio test=71.25; odds ratio=0.67; P<0.05). Plasma ferritin level had no predictive value (P=0.519). Subjects with CHr less than 27.4 pg had lower Hb level, MCH, CH, Tfsat, and iron levels than those with CHr 27.4 pg or more (P<0.05 for all). CONCLUSION: CHr level was a sensitive screening tool and the strongest predictor of iron deficiency in hospitalized infants with acute infection; it was cost saving and avoiding additional sampling. However its reference range should be established.

Coronary artery aneurysm is a rare disorder. It is defined as abnormal dilatation of coronary artery with diameter exceeding 1.5 times the adjacent normal segments. The incidence of coronary aneurysm is 2.6% in Caucasians and 0.25% in Asians. Over half of the former were associated with atherosclerotic coronary artery disease. However, 70 percents of the latter were nonobstructive coronary artery aneurysms. Coronary artery fistula is a rare disorder. It has been identified in only 0.2% of routine cardiac angiographic studies conducted over a 10-year period. The clinical spectrums are various, asymtomatic, asymptomatic murmur, dyspnea on exertion, fatigue, and congestive heart failure. The right coronary artery (56%) and left coronary artery(36%) are mainly involved in the origin site of congenital coronary artery fistula. The draining site of fistula are right ventricle(39%), right atrium(33%), and pulmonary artery(20%) and so on. This 54 years-old woman had intermittent chest tightness and an abnormal mediastinal shadow on chest roentgenogram and chest C-T examination, which was diagnosed as a mediastinal mass such as teratoma. We performed the operation under left anterolateral thoracotomy for mass excision. However, we knew the mass had the pulsating arterial blood flow through a fine needle puncture of the mass and that it was attached to the left ventricle. We believed the excision of mass on beating heart would be very dangerous. Therefore, we closed the wound without excising the mass. After several days, we performed an echocardiography and coronary angiography, We knew it was cardiac tumor. Incidentally, the patient had a tortuous coronary fistula from the right coronary artery to pulmonary trunk. Using cardiopulmonary bypass with moderate systemic hypothermia, the mass was resected and the fistula was clipped with surgical clips. Pathology of the specimen was a giant coronary arterial aneurysm.

Background/Aims: To investigate an effect of ML204 (an inhibitor of transient receptor potential canonical 4 and 5 [TRPC4/5] channels) on interstitial cells of Cajal (ICCs) and therefore determine whether TRPC4/5 channels act on ICC-generated pacemaker activity. Methods: We enforced whole cell patch clamp analysis, measurements of the intracellular Ca2+ concentration, and reverse transcription polymerase chain reaction to determine the effect of ML204 (10 μM) or englerin A (a selective activator of TRPC4/5 channeles, 10 μM) and the existence of TRPC4/5 in mouse small intestinal ICC. Results: Treatment of ICCs with ML204 or englerin A caused the membrane potentials to depolarize. This depolarization effect of membrane potentials by ML204 in ICCs was observed to be concentration-dependent. After treating Ca 2+ - and Na + -free solutions or flufenamic acid (a non-selective cation channel blocker), the pacemaker potentials in the ICCs were abolished. A specific anoctamin 1 channel blocker did not have any effect on the pacemaker activity in ML204-untreated control cells; however, they blocked ML204-induced pacemaker activity in ICCs. Specific primers designed against TRPC4 and TRPC5 detected the presence of TRPC4/5 in small intestinal ICCs, and the application of ML204 increased raise the frequency of Ca2+ oscillations in ICCs, as assessed using Fluo-4 AM. Conclusion The results implied that ML204 could not inhibit the pacemaker activity but depolarized the membrane potential of ICCs by regulating intracellular Ca2+oscillations and anoctamin 1 channels.

PURPOSE: This study was conducted in order to evaluate the possibility of improving the comprehension and satisfaction of patients discharged after receiving discharge instructions using a tablet personal computer (tablet PC), compared with conventional discharge instructions. METHODS: A randomized, prospective, consecutive, exploratory study was conducted on patients with ureteral stones in an emergency department (ED). The patients' objective comprehension, satisfaction, and subjective comprehension regarding their discharge instructions were compared with regard to discharge instruction (traditional verbal method, N=53 versus tablet PC method, N=53). RESULTS: No statistically significant differences in age, gender, or level of education were observed between the two groups. The mean number of correct answers regarding ureteral stones on the questionnaire was 2.35+/-1.02 in the conventional group (CG) and 3.37+/-0.9 in the tablet PC group (TG) (p<0.05). The score for satisfaction was 7.75 in the CG and 8.03 in the TG (p>0.05). The subjective comprehension score was 7.42 in the CG and 7.8 in the TG (p>0.05). CONCLUSION: Objective comprehension of ureteral stones showed improvement in the group with discharge instructions provided by the tablet PC. However, satisfaction and subjective comprehension did not show improvement.
