We report 2 cases of pediatric DNTs which presented with intractable seizures and no other associated neurologic abnormalities. They showed typical appearance of DNTs on neuroimaging and histopathology. Most patients with DNT can be cured by surgical treatment with exellent outcome and do not need ratio- or chemotheraphy. This study indicates that it is quite important to consider DNTs as one of differential diagnoses in patients with intractable seizures especially when they present only with seizures without other neurologic symptoms.

PURPOSE: The purpose of this study was to measure energy expenditure (EE) the metabolic equivalents (METs) of 13 common physical activities by using a portable telemetry gas exchange system (K4b2) and to assess the accuracy of the accelerometer (Actigraph GT3X+) by gender in Korean adults. METHODS: A total of 109 adults (54 males, 55 females) with normal BMI (body mass index) participated in this study. EE and METs of 13 selected activities were simultaneously measured by the K4b2 portable indirect calorimeter and predicted by the GT3X+ Actigraph accelerometer. The accuracy of the accelerometer was assessed by comparing the predicted with the measured EE and METs. RESULTS: EE (kcal/kg/hr) and METs of treadmill walking (3.2 km/h, 4.8 km/h and 5.6 km/h) and running (6.4 km/h) were significantly higher in female than in male participants (p < 0.05). On the other hand, the accelerometer significantly underestimated the EE and METs for all activities except descending stairs, moderate walking, and fast walking in males as well as descending stairs in females. Low intensity activities had the highest rate of accurate classifications (88.3% in males and 91.3% females), whereas vigorous intensity activities had the lowest rate of accurate classifications (43.6% in males and 27.7% in females). Across all activities, the rate of accurate classification was significantly higher in males than in females (75.2% and 58.3% respectively, p < 0.01). Error between the accelerometer and K4b2 was smaller in males than in females, and EE and METs were more accurately estimated during treadmill activities than other activities in both males and females. CONCLUSION: The accelerometer underestimated EE and METs across various activities in Korean adults. In addition, there appears to be a gender difference in the rate of accurate accelerometer classification of activities according to intensity. Our results indicate the need to develop new accelerometer equations for this population, and gender differences should be considered.

PURPOSE: Cyanate, known as one of the uremic toxins and derived spontaneously from urea, has several effects on the biologic substances including erythropoietin, antioxidant and ceruloplasmin. To find out the protective materials from the hazardous effect of cyanate in osteoblast, we added twenty amino acids, albumin globulin and hemoglobin in the culture media containing osteoblastic cells with cyanate. METHODS: Osteoblastic ROS 17/2.8 cells, exposed to various concentrations of sodium cyanate, were used to analyze for the cytotoxicity. The cyanate-induced cytotoxicity was assessed by the methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay by measuring the absorbance of the reaction solution at 570 nm. Viability of the treated cells was expressed as A570 of sample/A570 of control. The degree of the carbamylation was measured using trinitrobenzenesulphonic acid. The degree of the carbamylation in amino acid was about 50% in average. RESULTS: The degree of the carbamylation in albumin was increased depending on the incubation time with cyanate and the concentration of the cyanate. The degree of the carbamylation in globulin and hemoglobin was nearly zero. Asp, Glu, Leu, Trp and Tyr among the twenty amino acids revealed the protective effect against the damage induced by cyanate. And only albumin among the three proteins revealed the protective effect. CONCLUSION: On the basis of these results, Asp, Glu, Leu, Trp, Tyr and albumin are useful tools for the protection against damages by cyanate carbamylation.

Using dilution plating method, 47 fungal isolates were obtained from a soil sample collected from Dokdo in the East Sea of Korea in 2013. In this study, two fungal isolates, EML-MFS30-1 and EML-DDSF4, were confirmed as undescribed species, Metarhizium guizhouense and Mortierella oligospora in Korea based on current classification system using multi loci including rDNA internal transcribed spacer, large subunit, small subunit, and beta-tubulin (BTUB) genes. Herein, detailed morphological descriptions on characters of the undescribed fungal species as well as their molecular phylogenetic status are provided with comparisons to related species.

A fungal isolate EML-NCP01 was recovered from agricultural soil in Ulleung Island, Korea. Phylogenetic analysis of internal transcribed spacer and beta-tubulin genes identified the isolate as the Penicillium species P. raphiae. Morphologically, the EML-NCP01 isolate was identical to the previous description of P. raphiae. The species presented here has not been reported in Korea.

PURPOSE: Use of a home mechanical ventilator can shorten the hospitalization duration of children with chronic respiratory failure requiring long-term use of a mechanical ventilator. In this study, the researchers analyzed patients who had used a home mechanical ventilator. METHODS: From January 2009 to July 2014, we retrospectively investigated 15 patients under 18 years of age, from 2 hospitals, and their use of home mechanical ventilators. RESULTS: The median age of the patients was 55 months. Ten children were male, and 5 were female. As for the type of mechanical ventilators, 10 used a pressure type, 3 used a volume type, and 2 used a volume-mask type. Analysis of underlying diseases revealed that 10 children had neuromuscular disease, 3 had pulmonary disease, and 2 suffered from hypoxic ischemic encephalopathy. The number of patients who were discharged from the hospital with a home mechanical ventilator was 13. One child died of sepsis irrespective of the mechanical ventilator. Six patients had health insurance. But 9 did not. The group with insurance had the possibility of being discharged earlier than the group without. On readmission, the length of hospitalization was also reduced in patients who had used a home mechanical ventilator. CONCLUSION: Use of a mechanical ventilator at home is helpful in patients who need long-term use of a mechanical ventilator due to neuromuscular disease, chronic pulmonary diseases, and accidents because complications are rare and insurance coverage is feasible.

A 60-year-old female presented with a slowly growing, painful mass in the superolateral portion of the rightt high. Physical examination, roentgenography, bone scan and magnetic resonance imaging revealed a soft tissue masswith mineralization which did not involve bone or joint. A triangular-shaped, mineralized lesion was found in the superior side of the greater trochanter on simple radiograph and on magnetic resonance imaging. It had not been detected clinically, and was asymptomatic. The masses were removed en bloc and diagnosed as extra articular osteochondroma. Eight months postoperatively, pain had almost been relieved.

When the cervical cancer is diagnosed in early stage during pregnancy, the treatment can be postponed for fetal viability. This case presents a patient diagnosed as cervical cancer stage Ib1 during her pregnancy. The patient had 2 cycles of neoadjuvant chemotherapy (Paclitaxel-cisplatin) formerly and cesarean section was done at 33rd weeks of intrauterine pregnancy, then radical abdominal hysterectomy with bilateral pelvic lymph node dissection and paraaortic lymph node biopsy was immediately performed right after the delivery. For the baby born, there was neither complication nor congenital anomaly but mild bilateral ventriculomegaly seen on brain CT taken on 3 days after birth. This case offers a better chance for both mother and fetus while conserving fetal viability and managing the early cervical cancer during pregnancy through close follow up.

OBJECTIVE: To discover the risk factor of postpartum depression and whether this is different from the induced factor of prepartum depression and to clarify what is the recovery factor from prepartum depression. METHODS: In the first test stage, 310 pregnant women were examined and with their postpartum follow-up survey, materials from 85 people in total were retrieved. In order to predict the postpartum depression and find out the recovery factor from prepartum depression, longitudinal study was carried out. For the statistical analysis hierarchical regression analysis and MANOVA were used. RESULTS: Postpartum depression (Beck Depression Inventory; BDI score of 16 or greater) was prevalent amongst 22.4% of pregnant women and prepartum depression was experienced by 10.5% in pregnant women. There were no significant on psychological variable factor of prepartum and postpartum depression. Only preatum depression redicted 33% for postaprtum depression. In the case of depressed during pregnancy but not depressed after pregnancy, recovery factor is related to increase in self-esteem, husband support and improvement in marital satisfaction. Postpartum depression showed twice higher depression ration than prepartum depression and it was serious in terms of degree of depression. CONCLUSION: Postpartum depression is related with lack of husband support that is recovery factor from prepartum depression. Also, unstable attachment is vulnerable to depression but even people with unstable attachment can be recovered from depression with better marriage relationship. Even people without unstable attachment if husband support is reduced then it is suggested that can be subject to vulnerability in depression.
