To evaluate the risk and factors associated with seizure recurrence in children with epilepsy while receiving the adequate anticonvulsant treament, we studied 58 patients with newly diagnosed epilepsy who were followed prospectively for a median of 26 months (range 7 to 54). The results were as follows: 1) Forty-four of the 58 patients (75.9%) had recurrence of seizure. 2) The rate of recurrence according to type of seizure was observed to be 22 patients (68.8%) in generalized tonic-clonic seizure, 6 patients (85.7%) in simple partial seizure, 5 patients (83.3%) in complex partial seizure, 3 patients (100%) in mixed seizure, 2 patients (100%) in absence, 3 patients (100%) in infantile spasm, 1 patient (100%) in atonic seizure, 2 patients (50%) in secondary generalized seizure. There was no significant difference in the risk of recurrence observed among these seizure types. 3) The risk of recurrence varied according to the history of seizure, seizure recurrence was observed in 100% of the cases with history of neonatal seizure, 72.7% of the cases with febrile convulsion, and 73.3% of the cases with non-specific history. No significant difference was observed among these past history of seizure. 4) The rate of seizure recurrence according to electroencephalographic abnormalities did not differ significantly. Seizure recurrence was noted in 13 of the 18 patients with mildly disordered tracings (72.2%), 15 of the 20 patients with moderate abnormality (75.0%), and 12 of the 16 patients with severe abnormality (75.0%). 5) Recurrence rate according to cause of seizure was more significantly frequent in those with symptomatic epilepsy than in those with idiopathic type (100% vs 70.2%, p<0.05). 6) The frequency percentage of seizure recurrence by age groups of below 1 year, 1 to 3 years, 4 to 6 years, and above 6 years at onset of seizure were 100, 66.7, 57.1, and 72.7, respectively. The rate of seizure recurrence was significantly highest in patients aged below 1 year at onset of seizure. 7) There was significant difference in seizure recurrence between those with and without abnormalities as shown by neurologic examination (100% vs 70.8%, p<0.05). 8) There was no consistent difference in valproic acid serum levels between those who had a recurrence and those who did not. The patients receiving phenobarbital had significantly high serum levels of the phenobarbital in recurrent groups than those who had no recurrence. In conclusion, factors associated with an increased risk of seizure recurrence were early age at onset of epilepsy, symptomatic epilepsy, and neurologic abnormalities. We found no associations between risks of recurrence and types of epilepsy, or electroencephalographic abnormalities.

BACKGROUND: Dense breast reduced the sensitivity of mammography in breast cancer screening and known as an independent risk factor of breast cancer. The relationship between breast density and age, body mass index has studied. However, there are few studies on the relationship between breast density and lifestyle related disease. In this study, we investigated the relationship between mammographic breast density and lifestyle related disease. METHODS: Retrospective cross sectional research was carried out from people who visited a single health screening center in Busan from January 2015 to December 2015. We investigated age, past history of the subjects and measured their height, weight, blood pressure and waist circumference. The biochemical test was carried out using their blood. All patients underwent mammography. The breast density on mammography determined by the basis of American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) breast composition and 996 people was recruited. RESULTS: In the distribution of breast density, 16.3% of women (n=160) had dense breast. Age (under 49), body mass index (BMI) (underweight) were positively correlated with the BI-RADS composition category 3, 4 but the number of lifestyle related disease were negatively correlated (age ρ=0.17, BMI ρ=0.39, the number of lifestyle related disease ρ=-0.21). The odds ratio (OR) of dense breast increased with decreasing lifestyle related disease severity (OR=3.06, 95% confidence interval: 1.13-8.22, P=0.027). CONCLUSIONS: This study showed that the number of lifestyle related disease was negatively correlated with mammographic density. The OR of dense breast increased with decreasing lifestyle related disease severity. Therefore, primary physicians should consider negative correlation between breast density and lifestyle related disease in breast cancer screening.

This study was conducted to provide basic data on physiological and hematological characteristics, and organ weights of beagle dogs. A total of 237 beagle dogs were used to determine differences in physiological and hematological parameters, and organ weights depending on sex and age. The respiratory rate of both sexes tended to increase as they grew older and the female heart rate was slightly higher than that of males. Male and female body weights increased rapidly to 33 weeks old followed by a gradual increase to 41-weeks-old. The relative weight of the brain was negatively correlated with body weight, whereas the weight of reproductive organs was positively correlated with body weight. The platelet count of female dogs was slightly higher than that of males. The red blood cell, hemoglobin, and hematocrit of both sexes increased non-significantly with age. In the leukocyte differential count, the neutrophils, and eosinophils of both sexes tended to increase as they grew older, whereas basophils, lymphocytes, and monocytes decreased. In the serum biochemical profiles, alkaline phosphatase was slightly higher in males than females, while the total cholesterol of female dogs at 9-months-old was higher than that of males at the same age. Other biochemical components, including alanine aminotransferase, blood urea nitrogen, creatinine, triglyceride, and total protein increased non-significantly with age in both sexes. To conclude, we observe no significant physiological or hematological differences with sex or age, although decreasing and increasing trends were detected with some parameters. These data provide valuable reference indices of the normal physiological and hematological characteristics of beagle dogs, which should prove useful in toxicological and pharmacological studies.

The presence of pneumocephalus associated with insertion, maintenance, and removal of intravenous catheters is a rare radiographic finding, but may be clinically relevant. Various pathways have been proposed to explain the development of pneumocephalus, but none are well understood. We present a patient with hemicranial pneumocephalus secondary to removal of a central venous catheter as determined by computed tomography, and we propose a possible mechanism of the pneumocephalus.

Colonic atresia (CA) is the rare cause of intestinal obstruction, and diagnosis of CA is difficult. But only few research has been performed, so little information has been available. The purposes of this study was to analyze the clinical findings of CA so that help physicians make decision properly. Children with CA who were treated at the division of pediatric surgery at Asan Medical Center in the period from January 1989 to December 2011 were evaluated retrospectively. A total of 6 children were treated with CA. These accounted for 2.7% of all gastrointestinal atresias managed in Asan Medical Center. Only one child was premature and low birth weight, the others were fullterm neonates and showed normal birth weight. Vomiting and abdominal distension were common symptoms and simple X-ray and barium study were used for diagnose of CA. But only 66.7% of the babies were diagnosed as CA pre-operatively. And 2 children out of 6 underwent re-operation due to missed CA at the time of the first operation. In aspect of types of atresia, the type IIIa were two, type IV were two, type I was one case, and one child showed rectal stenosis due to rectal web. Various operations were done according to individual findings and associated diseases. The 50% (n=3) of children underwent the primary anastomosis and the others (n=3) underwent colostomy first and staged operation later for missed CA or associated disease. All of them were recovered any significant complications. Therefore, the prognosis of CA is satisfactory if diagnosis and surgical management could be made properly. But because of the low incidence of CA, delay of diagnosis and treatment may occur. To prevent delay of diagnosis, we suggest prompt evaluation of doubtful infant and careful inspection of distal patency of bowel including whole colon and rectum when operating patients with intestinal atresia at any level.

We analysed the 49 probands of autosomal dominant polycystic kidney disease (ADPKD) in Korea to elucidate clinical and genetic characteristics. 1) Family history of renal disease or ADPKD was taken from 44% of probands; hypertension 88%, cerebrovascular attack 64%, end stage renal disease 16%. 2) From the family screening with renal ultrasonography, we have confirmed dominant trait in 24 families. We found 2 families which have suspicious new mutations. 3) We performed linkage analysis of 15 families. The PKD-1 to non PKD-1 ratio was 13 : 2. 4) The male to femal ratio was 17 : 32 and age at diagnosis was 41 (24-65)years (mean (range)) in male, 45 (26-68) years in female. 5) The factors leading to the diagnosis of ADPKD were flank pain (23%), incidental finding (17%), palpable abdominal mass (11%), headache (9%) and gross hematuria (9%) 3) Hypertension (80%), azotemia (43%), flank pain (42%), renal calcification (42%), gross hematuria (33%) and cyst hemorrhage (25%) were renal complications. There were 2 renal cell carcinoma cases. 4)Liver cyst (82%) was the most common extrarenal manifestations. There were colonic diverticulosis (13%), cerebral artery aneurysm (7%), adrenal cyst (4%) and pancreatic cyst (2%). Results of our study revealed the clinical and genetic characteristics of ADPKD in Korea. We found only 44% of family history of renal disease, variable initial manifestations, variable renal and extrarenal complications. And we also found the similar percentage of PKD-2 (13%) to that (5-15%) of western countries, but it is necessary to study with more patients and families.

Journal of the Korean Association of Pediatric Surgeons 2014;20(2):33-37
PURPOSE: The purpose of this study was to compare the diagnostic accuracy of the non-invasive diagnostic methods and rectal suction biopsy for the detection of Hirschsprung disease (HD). METHODS: We reviewed diagnostic methods and results retrospectively in patients who underwent anorectal manometry, barium enema and rectal suction biopsy for the diagnosis of HD at Asan Medical Center from January 2000 to December 2012. RESULTS: There were 97 patients (59 neonates and 38 infants) in the study period. The overall accuracy of anorectal manometry for the diagnosis of HD was 71.1% and its sensitivity was 51.4% (48.1% in neonate and 62.5% in infant, respectively) and its overall specificity was 82.3% (81.3% in neonate and 83.3% in infant, respectively). The Overall accuracy of barium enema was 66.0% (72.8% in neonate and 55.3% in infant, respectively) and specificity of barium enema was 53.2% (56.3% in neonate and 50.0% in infant, respectively). These results were lower than those of anorectal manometry. The overall sensitivity of barium enema was 88.6% (92.6% in neonate and 75.0% in infant, respectively) and it was higher than the sensitivity of anorectal manometry. Histological studies confirmed HD in 35 patients, in one of whom the suction biopsy showed negative finding. CONCLUSION: Accuracy of non-invasive methods for diagnosis of HD in our study is lower than those in previous study, so we need to improve the quality of diagnostic tools in our hospital. We conclude that the rectal suction biopsy is the most accurate test for diagnosing HD, so the biopsy to confirm the diagnosis of the HD is very important.

BACKGROUND: The bispectral index (BIS) has been used as a monitor measuring hypnotic level of anesthesia or sedation. Recently EEG-entropy (M-Entropy(TM), S/5(TM) Entropy Module) has been provided and started to use domestically. This study was designed to compare the measured values between EEG-entropy and BIS monitor on general anesthesia and sedation. METHODS: Thirty patients undergoing total hysterectomy were anesthetized with propofol target controlled infusion (TCI), fentanyl, rocuronium and BIS, RE (response entropy), SE (state entropy), and hemodynamic variables were measured at the effect site concentration of 1.5-10.0 microgram/ml (P15-P100). On the other hand, fifteen patients undergoing breast biopsy were sedated with propfol TCI and BIS, RE and SE were measured at 0.9-2.3 microgram/ml (P09-P23). RESULTS: During general anesthesia, SE values were significantly lower than BIS or RE at baseline. But RE alone at P15, RE and SE at P20 were significantly higher than BIS. During sedation, SE values were significantly lower than BIS or RE at baseline-P09 and significantly lower than RE alone at P10-P15, and RE were significantly higher than BIS at P13-P20. After P21, RE and SE values fell abruptly and approached to BIS. CONCLUSIONS: EEG-entropy reflected hypnotic level well equal to BIS during general anesthesia. However, EEG-entropy did less reflected the hypnotic level than BIS during sedation.
