One of the complication during or after subclavian vein cannulation is intravascular catheter or wire embolization. Although some studies have reported safety of retaining foreign body embolization, and even death. The intravascular foreign body can be removed surgically or non-surgically. With improvement in instrument technology and technique, percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. Commonly used methods to remove intravascular foreign bodies are loop snare and basket technique. Sometimes biopy forcep can be used. We have experienced 2 cases of non-surgical removal of intravascular foreign bodies. One of the foreign bodies was 7cm wire fragment in right atrium(RA), the other was a 50cm guide wire. We used the standard loop snare technique for removal of 7cm wire fragment in RA and stone removal basket and 3.0mm ACS PTCA balloon to remove the 50cm short guide wire.

PURPOSE: This study was conducted to provide background information on nursing interventions to further enhance the quality of nursing practice and related professions, based on those performed for stroke patients. METHODS: The analysis was performed in light of 84 researches papers on nursing intervention published between 1990 and 2010, and based on NIC(Nursing Interventions Classification) and NOC(Nursing Outcomes Classification). RESULTS: 1. The quasi-experimental design was used as the most primary form of research design across 69 papers that constitute 82% of the total. 2. The number of nursing intervention methods identified throughout 84 research papers was 144. Based on the NIC that 90(62.5%) of those interventions fell into the physiological basic domain while 53(36.8%) belonged to the behavioral domain. 2) Interventions on activity and exercise management, physical comfort promotion, patient education conducted by class level of NIC were 40(27.78%), 34(23.61%), and 31(21.53%) respectively. 3) Outcomes of mobility, psychological well-being, energy maintenance, health & life quality measured by class of NOC among 317 dependent variables 79(24.92%), 64(20.19%), and 63(19.87%) respectively. CONCLUSION: Most interventions were classified as belonging to few particular domain types, which triggers needs for the development and application of multidisciplinary intervention methods through a more collective approach.

Double aortic arch is the most common type of symptomatic vascular ring. In most patients, the symptoms are manifested at birth or in early infancy. Double aortic arch usually has more severe symptoms than other types of complete vascular rings. We experienced one case of complete duplicated double aortic arch with left descending aorta and left patent ductus arteriosus. A one-day-old female neonate was transferred to our hospital because of mild dyspnea and stridor. She showed intractable CO2 retention and respiratory difficulty with time in spite of ventilator therapy. She died of respiratory failure 23 hours after birth. On autopsy, we found that the diameter of the vascular ring was 0.7cm in maximum extent. It was ovoid and contained trachea and esophagus. The trachea was flattened due to allowing 0.1x0.2cm. The compression level of the trachea was approximately 1cm from the tracheal bifurcation.

To evaluate a new reliable sclerosant of the gallbladder, we attempted gallbladder ablation with 10% phenol, and the results compared with those from using 95% ethanol which had been used previousy as gallbladder sclerosing agent in laboratory animals in other reports. After laparotomy, ligation of the cystic dusts with silk and cannulation of gallbladder with 18 gauge angiocatheter were done. Then, transcatheter administration of two different scleroing agents was performed in 8 rabbits respectively and normal saline in four rabbits as a control. Additionally, preliminary washing with each agent were implemented to prevent the dilutional effect of residual bile and bleeding. All animals survived without complication. Eight animals were used for each agent, four each being sacrified two weeks and six weeks after adminstration of sclerosing agents respectively. In our results, 10% phenol was more effective than 95% ethanol in denuding the gallbladder epithelium and promoting fibrosis of gallbladder wall, And it was relatively safe in regard to the dilutional effect of residual fluid and bleeding during procedure. Toxic effects on the liver evaluated by examination of histologic specimen were non-specific except for edematous swelling on some cases, which had also been observed on others including control group. 10% phenol can be considered to be a promosing sclerosant for gallbladder ablation, but further study of its toxicity is needed before its application on human gallbladder.

Atypical chronic myeloid leukemia (aCML), BCR-ABL1-negative is a rare myeloid neoplasm, especially in pediatric patients. The mutations identified in aCML have overlapped with those of other myeloid neoplasms. In recent studies, ruxolitinib, a Janus kinase (JAK) inhibitor, was found efficient in some patients of aCML with CSF3R mutation. Here, we report a pediatric case of aCML with CSF3Rmutation who did not respond to ruxoritinib, but was successfully rescued with hematopoietic stem cell transplantation (SCT). A stuporous 13-year-old boy was transferred with leukocytosis.Computed tomography showed an acute lobar intracranial hemorrhage in the left frontal lobe. The bone marrow aspirate demonstrated significant granulocytic proliferations with predominant dysplasia. Hydroxyurea and imatinib were initially administered to reduce leukocytosis. After BCR-ABL1 was found to be negative, imatinib was discontinued. After the identification of CSF3R mutation by customized targeted DNA sequencing (NGeneBio, Seoul, South Korea), ruxolitinib was added. He seemed to have hematologic and clinical responses on 2 months of ruxolitinib treatment, but the blast counts in the bone marrow increased. He underwent a full-matched unrelated peripheral blood SCT successfully 3 months after his diagnosis and has currently been disease-free 8 months since the transplantation. In conclusion, ruxolitinib for aCML with CSF3R mutation might not always induce a significant response but could be used as bridge to hematopoietic SCT.

BACKGROUND: Recurrent somatic SET-binding protein 1 (SETBP1) and splicing pathway gene mutations have recently been found in atypical chronic myeloid leukemia and other hematologic malignancies. These mutations have been comprehensively analyzed in adult AML, but not in childhood AML. We investigated possible alteration of the SETBP1, splicing factor 3B subunit 1 (SF3B1), U2 small nuclear RNA auxiliary factor 1 (U2AF1), and serine/arginine-rich splicing factor 2 (SRSF2) genes in childhood AML. METHODS: Cytogenetic and molecular analyses were performed to reveal chromosomal and genetic alterations. Sequence alterations in the SETBP1, SF3B1, U2AF1, and SRSF2 genes were examined by using direct sequencing in a cohort of 53 childhood AML patients. RESULTS: Childhood AML patients did not harbor any recurrent SETBP1 gene mutations, although our study did identify a synonymous mutation in one patient. None of the previously reported aberrations in the mutational hotspot of SF3B1, U2AF1, and SRSF2 were identified in any of the 53 patients. CONCLUSIONS: Alterations of the SETBP1 gene or SF3B1, U2AF1, and SRSF2 genes are not common genetic events in childhood AML, implying that the mutations are unlikely to exert a driver effect in myeloid leukemogenesis during childhood.

OBJECTIVE: To determine the efficacy of aquatic treadmill training (ATT) as a new modality for stroke rehabilitation, by assessing changes in gait symmetry, balance function, and subjective balance confidence for the paretic and non-paretic leg in stroke patients. METHODS: Twenty-one subacute stroke patients participated in 15 intervention sessions of aquatic treadmill training. The Comfortable 10-Meter Walk Test (CWT), spatiotemporal gait parameters, Berg Balance Scale (BBS), and Activities-specific Balance Confidence scale (ABC) were assessed pre- and post-interventions. RESULTS: From pre- to post-intervention, statistically significant improvements were observed in the CWT (0.471±0.21 to 0.558±0.23, p<0.001), BBS (39.66±8.63 to 43.80±5.21, p<0.001), and ABC (38.39±13.46 to 46.93±12.32, p<0.001). The step-length symmetry (1.017±0.25 to 0.990±0.19, p=0.720) and overall temporal symmetry (1.404±0.36 to 1.314±0.34, p=0.218) showed improvement without statistical significance. CONCLUSION: ATT improves the functional aspects of gait, including CWT, BBS and ABC, and spatiotemporal gait symmetry, though without statistical significance. Further studies are required to examine and compare the potential benefits of ATT as a new modality for stroke therapy, with other modalities.

The present study was aimed to investigate the effects of MB12662, a synthetic dunnione compound, on cisplatin-induced vomiting reflexes and intestinal, renal, immune system, and hematopoietic toxicities in ferrets and mice, respectively. Male ICR mice were orally administered MB12662 (5, 10, 25 or 50 mg/kg) for 10 days, during which intraperitoneally challenged with cisplatin (3.5 mg/kg) from day 4 to 7, and sacrificed on day 10 for the pathological examination. Male ferrets were orally administered MB12662 (25, 50 or 100 mg/kg) for 7 days, subcutaneously challenged with cisplatin (5 mg/kg), and monitored for vomiting reflexes and survival of the animals. Four-day injection of cisplatin (3.5 mg/kg) to mice caused body weight loss and degeneration and atrophy of intestinal villi, reducing villi/crypt ratio to a half level of control animals. Cisplatin also induced renal and hepatic toxicities, and depletion of splenocytes and bone marrow progenitor cells. The systemic toxicities including decreased villi/crypt ratio, immune system atrophy, splenocyte depletion, and decreased cellularity in bone marrow were improved by MB12662. Cisplatin (5 mg/kg) induced retching and emetic responses of ferrets, which were remarkably attenuated by MB12662 in a dose-dependent manner. All the ferrets pretreated with MB12662 survived the challenge of cisplatin, in comparison with 40% mortality in vehicle-treated animals, and blood parameters of nephrotoxicity and hepatotoxicity were markedly recovered. It is expected that MB12662 could be a candidate for the body protection against burden, including emesis, of chemotherapeutic agents.

Hemolytic uremic syndrome (HUS) is the most common cause of acute renal failure in children younger than 4 years and is characterized by microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia. HUS associated with diarrheal prodrome is usually caused by Shiga toxin-producing Escherichia coli O157:H7 or by Shigella dysenteriae, which generally has a better outcome. However, atypical cases show a tendency to relapse with a poorer prognosis. HUS has been reported to be associated with acute lymphoblastic leukemia (ALL) in children. The characteristics and the mechanisms underlying this condition are largely unknown. In this study, we describe the case of an 11-year-old boy in whom the diagnosis of ALL was preceded by the diagnosis of atypical HUS. Thus, patients with atypical HUS should be diagnosed for the possibility of developing ALL.

Spinal en plaque meningioma is rarely found in the spinal canal, although lateral sphenoid wing meningioma displays a propensity for growth en plaque. We encountered a case of completely circumferential spinal en plaque meningioma, which is an even rarer condition. Herein, we report the CT & MRI findings along with a review of the related literature.
