Pharmacologic therapy is still the primary management for epilpsy; however, surgical treatment is a reasonable therapeutic option for patients suffering from medically intractable seizures, especially temporal lobe epilepsy having a documented unilateral epileptogenic area. Thirty nine patients with pharmaco-resistant complex partial seizures underwent anterior temporal lobectomy and hippocampectomy in 38 cases and frontal cortisectomy in one case. On pathological examination, hippocampal sclerosis was a predominent pathologic finding and was identified in 18 cases. Other non-neoplastic lesions consisted of 5 cases of vascular lesions(2 cavernous angiomas, 2 arteriovenous malformations and 1 angiomatosis), 3 cases of fibrous nodule, 2 cases of cicatrical changes of cerebral cortex, and 1 case of parasitic infection. Neoplasms including two cases of oligodendroglioma and one case of anaplastic astrocytoma were also noted. In seven cases, there was no detectable lesion on gross and microscopic examination. On post-operative follow-up, seizures were completely terminated in most cases(31 cases, 79%). The rest of the patients also displayed marked alleviation of symptoms. The seizures tended to recur more aften among the patients with neoplasm or no pathologically detectable lesion. In order to detect any minute pathological lesion, thorough gross and microcsopic examinations are considered to be essential.

Neuropeptide Y (NPY) was a 36-amino acid peptide that biochemical structure to be resemble the pancreatic polypeptide in mammalian and it was first isolated from porcine brain by Tatemoto et al. (1982). It is now known to neurotransmitter or neuromodulator as well as it has important effects to sexual precocity, regulation of feeding behavior and function of pituitary gland in avians. The distribution and morphological study of NPY-immunoreactive neurons (NPY-IR) is studied in many experimental animal but in developing chick brain have been not studied. The present study provided the distribution and morphological study of NPY-IR in developing chick brain. The developing brain of Korean native chicks embryos at E8, E10, E12, E14, E16, E18, and E20 days of incubation were used. Experimental animals were perfused with 4% paraformaldehyde through the left ventricle and aorta. The brains were removed and transferred 30% sucrose, and then cut on a cryostat into 60 mm-thick. The tissue immunostained with free-floating and avidin-biotin complex (ABC) method. The results obtained in this study are that followings. The numerous of NPY-IR first observed at E8 days in the telencephalon of neostriatum, ectostriatum, archistriatum intermedium pars ventralis, nucleus taeniae and paleostriatum agumentatum, at E12 days in telencephalon of hippocampus, at E14 days in telencephalon of hyperstriatum. In the telencephalon, NPY-IR distributed predominantly in neostriatum and ectostriatum. shape of neuron's that E8 days of incubation were oval shape neurons and increased days of chicks was sphere, oval and many multigonal shapes. Their processes were also omnidirectional. The process of neuron's that E8 days of incubation was observed a few and weak immunity and increased days of chicks was numerous and strong immunity. According to increasing the days the morphology of NPY-IR showed the tendency to increase their sizes and numbers. We suggest that the regional differences in the distribution of NPY-containing neuron types may reflect adaptations of local neuronal circuits for specialized functions.

Congenital long QT syndrome (LQTS) is an inherited disease characterized by prolonged QT intervals and polymorphic ventricular tachycardia. The clinical manifestations vary from sudden cardiac death by ventricular arrhythmia to asymptom throughout life. In 1957, Jervell and Lange-Nielsen reported a syndrome of congen-ital sensory deafness associated with a prolonged QT interval in four children. The affected children had multiple syncopal episodes, and three died suddenly. The mode of inheritance is autosomal recessive. Affected persons are susceptible to recurrent syncope, and they have a high incidence of sudden death and short life expectancy. We report a case and review the literature on long QT syndrome diagnosed in a 30-year-old female with a history of convulsion and loss of consciousness during delivery.

Esophageal reflux of gastric contents causes esophageal mucosal damage and inflammation. Recent studies show that oxygen-derived free radicals mediate mucosal damage in reflux esophagitis (RE). Chlorogenic acid (CGA), an ester of caffeic acid and quinic acid, is one of the most abundant polyphenols in the human diet and possesses anti-inflammatory, antibacterial and anti-oxidant activities. In this context, we investigated the effects of CGA against experimental RE in rats. RE was produced by ligating the transitional region between the forestomach and the glandular portion and covering the duodenum near the pylorus ring with a small piece of catheter. CGA (10, 30 and 100 mg/kg) and omeprazole (positive control, 10 mg/kg) were administered orally 48 h after the RE operation for 12 days. CGA reduced the severity of esophageal lesions, and this beneficial effect was confirmed by histopathological observations. CGA reduced esophageal lipid peroxidation and increased the reduced glutathione/oxidized glutathione ratio. CGA attenuated increases in the serum level of tumor necrosis factor-alpha, and expressions of inducible nitric oxide synthase and cyclooxygenase-2 protein. CGA alleviates RE-induced mucosal injury, and this protection is associated with reduced oxidative stress and the anti-inflammatory properties of CGA.

BACKGROUND: This study was undertaken to determine current practice for preoperative anxiety reduction in Korean children. METHODS: An email survey of all members (n = 158) of the Korean Society of Pediatric Anesthesiologists was conducted from November 2014 to January 2015 to assess current practice, preferences, and general opinions regarding pharmacological and non-pharmacological interventions performed to alleviate preoperative anxiety in children prior to general anesthesia. RESULTS: Forty-one anesthesiologists completed the survey; a response rate of 26%. Only 4.9% of respondents undertook anxiety reduction according to a written hospital policy, and 95.1% did not. Most respondents (70.7%) performed anxiolytic intervention guided by informally standardized hospital protocol. In clinical practice, 90% of respondents used pharmacological and/or non-pharmacological intervention to alleviate anxiety in children. Nearly half of the respondents (53.7%) used premedication to reduce anxiety, and midazolam was most frequently used. Parental presence during induction of anesthesia was considered the most effective non-pharmacological intervention (60.4%), and was allowed by 78% of respondents, and watching a video was considered the second most effective intervention (27.1%). CONCLUSIONS: Korean pediatric anesthesiologists use both pharmacological and non-pharmacological interventions to alleviate preoperative anxiety, and these interventions are generally guided by an informally standardized hospital protocol. Anesthesiologists requiring effective anxiety reduction prefer pharmacological intervention and most commonly use intravenous midazolam, whereas those that want safe anxiety reduction prefer non-pharmacological intervention and most frequently use parental presence during induction of anesthesia.

PURPOSE: To investigate prognostic factors influencing on local recurrence, distant metastasis and event-free survival of liposarcomas. MATERIALS AND METHODS: Fifty-two patients managed for liposarcomas since 1993 were analyzed respectively in the view of prognostic influence of patient age, tumor size, location, histologic type, histologic grade, resection type, surgical margin, chemotherapy and radiation therapy on local recurrence, distant metastasis and event-free survival. The mean follow up period was 39 months. The univariate and multivariate regression analysis were performed for statistical evaluation. RESULTS: The local recurrences occurred in 11 patients (21.2%) and distant metastasis in 4 patients (8%), Event-free survival rate at 4 year follow up was 67%. In univariate analysis, histologic grade, surgical margin, chemotherapy and radiation therapy were significant prognostic factors on local recurrence (p<0.05). However, histologic grade lost its significance in muitivariate analysis. Trunk location revealed higher rate of distant metastasis than extremity location. In univariate analysis on event-free survival. histologic grade and chemotherapy were significant factors (p<0.05). No factor remained significant in multivariate analysis. CONCLUSION: Considering selection bias, positive surgical margin was negative prognostic factor on local recurrence. Liposarcomas arisen in trunk revealed higher rate of distant metastasis. There was no independent prognostic factor on event-free survival of patients with liposarcomas.

BACKGROUND: Our aim was to make a comparative analysis of radiological and clinical outcomes of using either one or two interlocking distal screws on a Polarus intramedullary nail for the internal fixation of humeral shaft fractures. METHODS: From January 2008 to March 2014, we enrolled 26 patients with humeral shaft fractures who were operated on using intramedullary nails. The patients were divided into 2 groups according to how many interlocking distal screws were used to lock the Polarus nail: in group 1, a single interlocking distal screw was used in 12 patients; and in group 2, double interlocking distal screws, in 14 patients. We compared the degree of recovery of the displaced fracture fragments between the two groups. To compare the nonunion and shoulder function, we assessed each patient's modified American Shoulder and Elbow Surgerns (ASES) score. RESULTS: We found that 10 of 12 fractures achieved union in group 1, and 13 of 14 fractures, in group 2. We did not find a meaningful difference in the time to bone union between the two groups. The percentage of recovery of displaced fracture fragments until union was 66.9% for group 1 and 59.41% for group 2. At the final follow-up, we found that the scores for shoulder joint modified ASES was 78.7 for group 1 and 80.7 for group 2. CONCLUSIONS: Our results show that if locked appropriately, even a single screw on a Polarus nail can provide satisfactory radiological union and improved clinical outcome after intramedullary nailing of humeral shaft fractures.
