The outcome of hematopoietic stem cell transplantation in Korean children with hemophagocytic lymphohistiocytosis.Pediatr Transplantation 2010: 14:735–740. © 2010 John Wiley & Sons A/S.</P><P>Abstract: </P><P>Chemoimmunotherapy-based treatments have improved the survival of patients with HLH, but outcomes of the patients are still unsatisfactory. We report here the outcome of Korean children with HLH who underwent HSCT, which was analyzed from the data of a nation-wide HLH registry. Retrospective nation-wide data recruitment for the pediatric HLH patients diagnosed between 1996 and 2008 was carried out by the Histiocytosis Working Party of the Korean Society of Hematology. Nineteen patients who received HSCT among the total of 148 enrolled children with HLH were analyzed for the transplant-related variables and events. The probability of five-yr survival after HSCT was 73.3% with a median follow-up of 57. Two months compared to 54.3% for the patients who were treated with chemoimmunotherapy only (p<I> </I>=<I> </I>0.05). The reasons for HSCT were active disease after eight wk of initial treatment (n = 9), relapsed disease (n = 5), and FHL (n = 5). Fourteen patients are currently alive without disease after HSCT, four patients died of treatment-related events (infection in two and graft failure in two) at early post-transplant period, and one patient died of relapse at one yr post transplantation. The survival of patients who were transplanted because of active disease after eight wk of initial treatment was worse compared to those patients who had inactive state at that time (60.6% vs. 100%, respectively, p<I> </I>=<I> </I>0.06). Of the four patients who received transplants using cord blood, three died of graft failure (n = 2) and relapse (n = 1). The five-yr probability of survival after HSCT according to the donor type was 85.7% for the MRDs (n = 6), 87.5% for the MUDs (n = 8), and 40% for the MMUDs (n = 5) (p<I> </I>=<I> </I>0.03). Other variables such as age, CNS involvement at the time of diagnosis, the etiology of HLH (familial or secondary), and the conditioning regimens had no influence on the five-yr OS of the HLH patients who underwent HSCT. HSCT improved the survival of the patients who had familial, relapsed, or severe and persistent SHLH in the Korean nation-wide HLH registry. Although numbers were small, these results are similar to other reports in the literature. The disease state after initial treatment, the stem cell source of the transplant, and the donor type were the important prognostic factors that affected the OS of the HLH patients who underwent HSCT.</P>

Waste supplied by Pilot-scale gasification system was necessary to mechanically processed to conform to the gasification reaction. In mechanical treatment facilities, MSW was ground to less than the size of 100~150 mm. In addition, eliminating the non-combustible material and water is able to minimize the energy loss in the gasification reaction. In this study, we Case study for mechanical pre-treatment of waste to be supplied to the gasification facility. By applying the characteristics of the obtained optimal waste Case study, was carried out Excel-based gasification modeling. Furthermore, we compared the production characteristics of the results experimentally obtained synthesis gas obtained in the gasification modeling. Production purpose of the synthesis gas is converted to renewable energy using gas engine or chemical process. To these conversion processes, such as hydrogen cyanide and ammonia are required for the removal of gaseous pollutants. The removal efficiency of a typical wet purification process that consists in this experiment facility was evaluated.

Induction of general anesthesia with direct laryngoscopy and tracheal intubation is accompanied by undesirable transient hemodynamic responses such as hypertension, tachycardia and arrhythmia. Many aproaches to attenuate these responses were made and opioid injection is one of effective methods. This study was done to examine blunting effect of low dose fentanyl, which was injected intravenously 5 minutes before tracheal intubation, on the adverse hemodynamic changes following direct larygoscopy and tracheal intubation. Ninety patients, ASA physical status Ⅰ, scheduled for elective surgery, were selected randomly. These were divided into three groups ; control group (n=30), group F2 (fentanyl 2 ㎍/㎏, n=30) and group F5 (fentanyl 5 ㎍/㎏, n=30). Fentanyl were injected 3 minuted before induction with thiopental sodium (3-5 mg/kg) and succinylcholine (1 mg/kg) i.v.. Laryngoscopy and endotracheal intubation were performed 5 minutes after fentanyl injection. After the completion of intubation, 50% nitrous oxide in oxygen and 2.0 vol% enflurane were inhaled. Blood pressure and heart rate were measured before intubation and 1 minute after intubation. After fentanyl injection, frequency of hypoxemia(arterial hemoglobin-oxygen saturation<90%) and apnea were measured and also dysrhythmia development after intubation were measured. Systolic, diastolic and mean arterial blood pressure were blunted in F2 and F5 group. And diastolic blood pressure showed significant difference between F2 and F5 group. Heart rate was not blunted in F2 group but in F5 group significantly. There was one of apnea and loss of consciousness in F5 group and no arrhythmia in both F2 and F5 groups. Hypoxemia was developed 33% in F2 group and 57% in F5 group. In summary, injection of fentanyl more than 5 ㎍/㎏ is needed to attenuate heart rate increase. And increase of blood pressure in F5 group was more blunted than in F2 group, but it was not significant statistically except diastolic blood pressure.

Suppressor of MEK null (SMEK)/protein phosphatase 4 catalytic subunit (PP4C) is a key regulator of hepatic gluconeogenesis.

<P>Fasting promotes hepatic gluconeogenesis to maintain glucose homeostasis. The cAMP-response element binding protein (CREB)-regulated transcriptional coactivator 2 (CRTC2) is responsible for transcriptional activation of gluconeogenic genes and is critical for conveying the opposing hormonal signals of glucagon and insulin in the liver. Here, we show that suppressor of MEK null 1 (SMEK1) and SMEK2 [protein phosphatase 4 (PP4) regulatory subunits 3a and 3b, respectively] are directly involved in the regulation of hepatic glucose metabolism in mice. Expression of hepatic SMEK1/2 is up-regulated during fasting or in mouse models of insulin-resistant conditions in a Peroxisome Proliferator-Activated Receptor-gamma Coactivator 1관 (PGC-1관)-dependent manner. Overexpression of SMEK promotes elevations in plasma glucose with increased hepatic gluconeogenic gene expression, whereas depletion of the SMEK proteins reduces hyperglycemia and enhances CRTC2 phosphorylation; the effect is blunted by S171A CRTC2, which is refractory to salt-inducible kinase (SIK)-dependent inhibition. Taken together, we would propose that mammalian SMEK/PP4C proteins are involved in the regulation of hepatic glucose metabolism through dephosphorylation of CRTC2.</P>

We propose an idea to verify personal identification. including security verification of identification(ID) cards so that they cannot easily be reproduced. The encrypted image is made by a fully phase image encryption technique that uses the double random-phase encoding. This encrypted image can be decrypted only when the corresponding phase codes are used for decryption. Therefore the information of the random-phase mask plays a key role when the encrypted image is decrypted. The encrypted image can be optically recovered and automatically verified for personal identification by the 4-f optical correlation system. A personal identification number is discriminated and recognized by the MMACE filter. and then authenticity of the card is verified by the optical wavelet matched filter(0WMF). Computer simulation results are presented.

Seizure with Subdural Hemorrhage in an Infant with Unrecognized Hemophilia A: Case Report of Mimicking Febrile Convulsion

( Yoon Zi Kim ),( Hoi Soo Yoon ),( Eun Hye Lee ) 경희대학교 경희의료원 2021 慶熙醫學 Vol.36 No.1

Seizure is the most common neurologic emergency in children, especially higher occurrence among infants and toddlers. Because the potential etiology of seizure in children is various, an accurate diagnosis is challenging. Even more, seizure which is associated with post-traumatic brain injuries is not common. We present one patient with hemophilia A, who presented with prolonged focal seizure and subdural hemorrhage. This patient had no family history of hemophilia but showed prolonged active partial thromboplastin time and severely low level of factor VIII (1%). This case highlights the management of prolonged focal seizure and the importance of performing neuroimaging and identifying underlying disease among children with seizure.
