Special anesthetic considerations were required for children with acute or chronic liver disease. We experienced a case of dental treatment to control infection under general anesthesia in the 2-year-old girl with liver failure. She was also scheduled for liver tansplantation. Her preanesthetic results of liver function test, electrolytes, and coagulation panel were unstable and out of normal ranges. Uneventful anesthetic induction using isoflurane and atracurium and nasotracheal intubation were carried out. General anesthesia was maintained with isoflurane for 2 hours. Oozing from multiple extraction sites was sustained, so the transfusion of platelet concentration 1 units, fresh frozen plasma 1 unit, and packed red blood cell 1 unit was done. She was recovered without complication but was transferred to pediatric intensive care unit for wound care with her endotracheal tube kept. She was transferred to a ward without noticeable complications next day. So we report this successful case of anesthetic management for dental treatment in a child with liver failure.

Purpose: This study was to measure and identify the differences of perceived confidence in practice of core basic nursing skills performed by new graduate nurses in Korea. Methods: The tool used in this study was a questionnaire for measuring the confidence in 20 items of core basic nursing skills which was structured based on Korean Accreditation Board of Nursing Education tool. 231 new graduate nurses participated in this study. The reliability of this questionnaire had Cronbach's ${\alpha}$ .918. Results: Subjects who experienced simulation education and standard patient education were 86.6% and 35.9%, respectively. Item enema intervention, tracheostomy care, and blood transfusion showed low practice confidence level. These items showed significant differences on whether the subjects experienced simulation and clinical practicum or not. Conclusion: Developing and managing clinical education program under deep cooperation between practicum agency and clinical instructor are needed. Simulation practicum will complement insufficient core basic nursing skills between newly graduated nurses before they allocate at the clinical department.

Purpose: The study aimed to evaluate the changes of body temperature and to identify the factors related to changes during surgery in burned patients. Methods: A retrospective study was conducted by reviewing the medical records of 439 adult burned patients who had a surgery under general anesthesia at the Burn Center of a university hospital. Results: After surgery, body temperature of the burned patients declined from $36.6^{\circ}C$ to $35.2^{\circ}C$; 52.2% were hypothermia. There were significant differences in the changes of body temperature according to the participants' characteristics including American society of anesthesiologists physical status, type of burn injury, total burn surface area, range of exposure, operation time, anesthesia time, amount of fluid, blood transfusion, use of tourniquet, and the method of warming therapy. Factors that influence the temperature changes were total burn surface area (${\beta}=0.26$), operation time (${\beta}=0.25$), amount of fluid (0.20), and warming therapy including 'Room temperature setting + Heated circuit + Hot line'(${\beta}=0.09$) and 'Room temperature setting+one of others'(${\beta}=0.08$). Conclusion: Burned patients experienced a decrease of their body temperature during surgery despite of warming therapy. A nursing protocol is needed to provide an appropriate warming therapy based on their characteristics in burned patients.

Necrotizing enterocolitis (NEC) is one of the most critical morbidities in preterm infants. The incidence of NEC is 7% in very-low-birthweight infants, and its mortality is 15 to 30%. Infants who survive NEC have various complications, such as nosocomial infection, malnutrition, growth failure, bronchopulmonary dysplasia, retinopathy of prematurity, and neurodevelopmental delays. The most important etiology in the pathogenesis of NEC is structural and immunological intestinal immaturity. In preterm infants with immature gastrointestinal tracts, development of NEC may be associated with a variety of factors, such as colonization with pathogenic bacteria, secondary ischemia, genetic polymorphisms conferring NEC susceptibility, anemia with red blood cell transfusion, and sensitization to cow milk proteins. To date, a variety of preventive strategies has been accepted or attempted in clinical practice with regard to the pathogenesis of NEC. These strategies include the use of breast feeding, various feeding strategies, probiotics, prebiotics, glutamine and arginine, and lactoferrin. There is substantial evidence for the efficacy of breast feeding and the use of probiotics in infants with birth weights above 1,000 g, and these strategies are commonly used in clinical practice. Other preventive strategies, however, require further research to establish their effect on NEC.

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous $H_2$ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

A new method to calculate the transmittable prevalence of an epidemic disease is proposed based on a back-calculation formula. We calculated the probabilities of reactivation and of parasitemia as well as transmittable prevalence (the number of persons with parasitemia in the incubation period) of malaria in South Korea using incidence of 12 years(2001-2012). For this computation, a new probability function of transmittable condition is obtained. The probability of reactivation is estimated by the least squares method for the back-calculated longterm incubation period. The probability of parasitemia is calculated by a convolution of the survival function of the short-term incubation function and the probability of reactivation. Transmittable prevalence is computed by a convolution of the infected numbers and the probabilities of transmission. Confidence intervals are calculated using the parametric bootstrap method. The method proposed is applicable to other epidemic diseases in other countries where incidence and a long incubation period are available. We found the estimated transmittable prevalence in South Korea was concentrated in the summer with 276 cases on a peak at the $31^{st}$ week and with about a 60% reduction in the peak from the naive prevalence. The statistics of transmittable prevalence can be used for malaria prevention programs and to select blood transfusion donors.

A 7-year-old, intact male Pomeranian(weighing 2.2 kg), was presented with clinical signs of prolonged anorexia, polydypsia/polyuria, severe azotemia, proteinuria and heart murmur. Diagnostic studies found chronic kidney disease, severe hypertension and hypertrophic cardiomyopathy. The dog was treated with 2-day peritoneal dialysis, blood transfusion, anti-hypertensive therapy with amlodipine and conservative therapies direct to chronic renal failure. This is a rare case of hypertensive cardiomyopathy complicated with chronic kidney disease in dogs.

The management of Patent Ductus Arteriosus[PDA] with heart failure and cardiac cachexia in premature infants have been a disturbing and controversial problem in the field of pediatric cardiovascular surgery.We analysed our experiences to determine the rationale of surgical closure of PDA in infants . During a period of 7 years from January 1986 to December 1992, 12 infants under 2 months of age underwent operations for "hemodynamically significant" PDA which had caused severe heart failure.There were 6 male and 6 female patients. Their mean gestational age was 33.8 weeks and their mean body weight was 1990 g. ranged from 710 g. to 2900 g. Mean age at operation was 28.5days. Seven patients had history of Indomethacin trial. All patients were operated with double ligation technique under general anesthesia.There was no mortality and blood transfusion was not necessary in any patient during the operation.In all cases, we could confirm the complete closure of PDA after operation by follow-up echocardiography.Two patients died during their hospital stay and 1 patient died at 6 months after operation. The causes of death were sepsis with congestive heart failure, necrotizing entero colitis and pneumonia respectively.We can not detect any operation related complication which resulted in permanent sequelae as well as delayed complications related to nerve damage. These results indicate that surgical ligation of PDA in infants with severe heart failure is relatively safe and effective.effective.

Purpose: Tc-99m MDP bone scan was performed to evaluate a generalized bone pain in a 24-year-old male chronic myelogenous leukemia patient who received bone marrow transplantation at 7 months ago. The patient had received large amounts of blood transfusion for managing symptoms related to anemia. Bone scan revealed substantial splenic tracer uptake. Magnetic resonance image and laboratory evidence of hemochromatosis suggests that the presence of large quantities of iron in the spleen of this patient may have been responsible for the splenic uptake of the bone scanning agent. The authors report a case of splenic hemochromatosis incidentally found on Tc-99m MDP bone scan.

A 62-year-old female patient had goiter for twenty years. She visited out-patient clinic with a hoarse voice and intermittent breathing difficulties. About protruding 15cm sized mass located the anterior neck and right vocal cord paralysis was observed. Preoperative CT scan was strongly suspected of thyroid gland cancer and cervical lymph node metastasis. Therefore, fine needle aspiration test was performed and surgical treatment was planned with the histopathologic results (papillary thyroid carcinoma). Surgery was performed with total thyroidectomy, bilateral cervical lymph node dissection, and right selective nodal lymph node dissection (level II-V). During operation right thyroid seemed to be adherent to surrounding tissue and the blood vessels were extremely engorged. There was hypotensive crisis because of intraoperative excessive bleeding. However it was managed by repetitive transfusion. The operation was completed without abnormalities. She underwent 4 times of bleeding control operation due to postoperative bleeding. After complications were improved, we are currently undergoing out-patient follow up without morbidity.
