PURPOSE: We carried out this study to determine if there is any difference in the occurrence rate of the epileptiform discharge between awake EEG and sleep EEG and if there are any factors influencing on the occurrence rate of EEG. METHODS: This study included 178 epileptic children who had visited neurology clinic of the department of pediatrics, Pusan National University Hospital from July 2005 to July 2006. The medical and EEG records of these children who had had both awake EEG and sleep EEG were reviewed. We analysed the occurrence rate of the epileptiform discharge between awake EEG and sleep EEG. We investigated the related clinical factors which included sex, seizure types, underlying causes, age at first seizure, antiepileptic drug (AED) medication, age at recording, and background activity. RESULTS: Among 178 epileptic children, 91 patients (51.1%) showed epileptiform discharge in awake or sleep states, 10 patients (11.0%) abnormal only in awake, 40 patients (44.0%) abnormal only in sleep, 41 patients (45.0%) abnormal in both awake EEG and sleep EEG. The occurrence rate of sleep EEG was 81 of 178 patients (45.5%) which was more than that of the awake EEG (28.7%) (P<0.001). The occurrence rate of sleep EEG is more than that of the awake EEG regardless of sex and underlying causes. But there is no significant difference from awake EEG and sleep EEG in finding the epileptiform discharge in the patient with generalized seizure, younger than 5 years old at first seizure, younger than 10 years old at recording, no antiepileptic medication, and abnormal background activity. CONCLUSION: The sleep EEG is thought to be more helpful in the diagnosis of childhood epilepsy.

Fibromatous tumors of the ovary are considered to originate from specialized ovarianstromal cells and account for approximately 4% of all ovarian neoplasms. Most ovarianfibromatous tumors are benign, but infrequently there are histologically malignant appearances.Malignant fibromatous tumor can be categorized into two separate types of tumorsrelating to prognosis, cellular fibroma and fibrosarcoma. The cellular fibroma has one tothree mitotic counts per 10 high power fields(HPF). Unless an adhesion or rupture appearson this tumor, recurrence should not happen after operation. Furthermore, where themitotic count per 10 HPF is over four, it is classified as a very bad fibrosarcoma case interms of prognosis.We have met a case of large ovarian fibrosarcoma with has ten mitotic counts per10 HPF. We hereby report this case with the brief review of literatures.

PURPOSE: Papillary thyroid carcinoma (PTC) is the most common malignant tumor of the thyroid and BRAFV600E mutation is the most frequent genetic alteration in PTC. BRAFV600E mutation has been demonstrated as a prognostic biomarker for prediction of poor clinicopathological outcomes, such as increased incidence of extrathyroidal extension, lymph node metastasis, and advanced stage. However, there is conflicting literature regarding the association of BRAFV600E mutation and aggressive clinicopathological features. In this study, we investigated the prevalence of BRAFV600E mutation in PTC and determined the association of BRAF mutation with indicators of poor prognosis for PTC. METHODS: We reviewed 1009 patients with PTC, who underwent thyroid surgery at Kyungpook National University Hospital between January 2013 and March 2014. BRAFV600E mutation analysis was performed using real-time polymerase chain reaction based amplification of DNA extracted from paraffin-embedded tumor specimens. RESULTS: BRAFV600E mutation was detected in 863 (85.5%) patients. In univariate analysis, histologic subtype, extrathyroidal extension, and advanced stage showed significant association with BRAFV600E mutation. In addition, concurrent Hashimoto's thyroiditis showed an association with low prevalence of BRAFV600E mutation. However, no statistically significant association was observed for age, gender, multifocal or bilateral tumor, and lymph node metastasis. Multivariate analysis showed an independent association of extrathyroidal extension with BRAFV600E mutation. CONCLUSION: In this study, extrathyroidal extension of PTC is an independent prognostic factor associated with BRAFV600E mutation status. However, conduct of further large scale studies with long term follow up is required before the BRAF mutation can be conclusively recommended as a prognostic biomarker.

PURPOSE: The aims of this study were to investigate whether parathyroid score can predict hypocalcemia after total thyroidectomy with central lymph node dissection (CLND) and to determine clinical value of parathyroid score for treatment of hypocalcemia. METHODS: A prospective review of 209 patients who underwent total thyroidectomy with CLND for papillary thyroid cancer from January to December 2012 was conducted. Parathyroid score was designed based on the number and color of parathyroid preservation (Save and intact color of a parathyroid was 2; Save but mild discoloration was 1.5; Not identification was 1.2; Autotransplantation was 1.0; Sacrifice was -1). RESULTS: The mean numbers of parathyroid glands were as follows: save & intact color was 2.0; save & mild discoloration was 0.8; not identification was 0.8; autotransplantation was 0.4. The average parathyroid score was 6.54+/-0.69 (range 3.4~8.0). The average PTH was 16.3 at the 1st POD. Transient and permanent hypocalcemia were 33.4% (70/209) and 0.9% (2/209), respectively. Parathyroid score was 6.78+/-0.54 in patients without transient hypocalcemia, 5.93+/-0.67 with hypocalcemia, parathyroid score was significantly lower in transient hypocalcemia, abnormal PTH at the 1st POD (P<0.001, P<0.001). CONCLUSION: Parathyroid score may predict patients at risk of developing transient hypocalcemia after total thyroidectomy with CLND.

Adrenocortical carcinoma (ACC) is a rare malignancy with poor prognosis, and it can be classified as either a functional or nonfunctional tumor. Affected patients usually present with abdominal pain or with symptoms related to the mass effect or hormonal activity of the tumor. Several cases of spontaneously ruptured nonfunctional adrenocortical carcinoma have been reported, but no case of a spontaneous rupture of functioning adrenocortical carcinoma has been described. We report a functioning adrenocortical carcinoma that spontaneously ruptured during a work-up.

OBJECTIVE: To analyze the hospitals related rehabilitation, which were designated for industrial accident compensation insurance, focusing faculties and facilities by administrative district. METHOD: Total 1,031 hospitals having more than 30 beds were included. We investigated the numbers of hospital beds, medical departments, medical doctors, nurses, physical therapists, and occupational therapists of each hospital with official document of industrial accident compensation insurance. And we classified and analyzed all data by administrative district. RESULTS: The average of each objects were estimated as following orders: total number of hospital beds (131.5); medical departments (5.8); medical doctors (11.2); nurses (33.8); physical therapists (4.2); occupational therapists (0.9). The percentage of hospitals with department of rehabilitation medicine was 28.4% in total, 26.7% in hospital and 35.3% in general hospital. Mean numbers of hospital beds, medical departments, medical doctors, nurses and physical therapists did not showed disparity among the administrative districts. However, the percentages of hospitals with department of rehabilitation medicine and of hospitals with occupational therapists showed disparity among the administrative districts. The regional distribution of hospitals with department of rehabilitation medicine showed similar distribution, as that of occupational therapists. CONCLUSION: These results demonstrate faculties and facilities of hospitals under the industrial accident compensation insurance which are related with rehabilitation treatment. We believe that these results would be helpful for constructing certification system of rehabilitation hospital and for further research about rehabilitation treatment associated with industrial accident compensation insurance.

Rare side effects of bromocriptine, such as, trigermial neuralgia, have been reported in patients with pituitary adenoma but no such case has been reported in post-stroke patients. This case reports on a stroke patient who developed trigeminal neuralgia after bromocriptine therapy. A 48-year-old man, diagnosed with left middle cerebral artery territory infarction and transcortical motor aphasia, was prescribed with 2.5 mg of bromocriptine. After two days, he complained of pain in the right trigeminal nerve distribution. Brain MRI, facial EMG, blink reflex, revealed no abnormalities. His pain showed no relief to various pharmacological agents. However, pain disappeared with discontinuation of bromocriptine and recurred again with readministration. In addition, pain intensity correlated with increase of bromocriptine dosage. Based on these findings, we concluded that patient' trigerminal neuralgia was related to bromocriptine administration. An antidote, which consisted of a dopamine antagonist was prescribed together with bromocriptine and the patient subsequently showed relief of pain and improvement of aphasia.

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the effect of pulmonary valve replacement (PVR) on exercise capacity and determine cardiopulmonary exercise (CPEX) parameters associated with improvement in right ventricle (RV) function. SUBJECTS AND METHODS: We retrospectively analyzed CPEX and magnetic resonance imaging parameters in a total of 245 patients who underwent PVR from January 1998 to October 2015. In addition, we analyzed the characteristics of the patients who showed improved exercise capacity after PVR. RESULTS: Twenty-eight patients met the inclusion criteria for the study. CPEX parameters after PVR showed no significant changes in all patients. However, baseline predicted peak oxygen uptake (VO2(peak)) (%) value was significantly lower in patients with significant improvement in exercise capacity after PVR, as compared to patients who showed decreased exercise capacity after PVR (60.83±10.28 vs. 75.81±13.83) (p=0.003). In addition, patients with improved exercise capacity showed a positive correlation between the change of right ventricular ejection fraction (RVEF) (%) and the change of anaerobic threshold (r=0.733, p=0.007); whereas, patients with decreased exercise capacity showed a negative correlation between the change of RVEF (%) and the change of predicted VO2(peak) (%) (r=−0.575, p=0.020). CONCLUSION: The importance of predicted VO2(peak) (%) in evaluating exercise capacity differentiated from other CPEX variables. The change of anaerobic threshold and predicted VO2(peak) (%) might be a useful predictor of the change in RV function after PVR.

To determine the distinction of primary ovarian carcinoma from metastatic ovariancarcinoma, the author studied total 40 cases of malignant tumors(13 primary ovarian carcinomas:7 serous, 4 mucinous, and 2 endometrioid, 7 metastatic ovarian adenocarcinomas,10 gastric adenocarcinomas and 10 colonic adenocarcinomas) using primary antibody to CEA,CK7, CK20 and CK18. The results were summerised as follows: The expression of CK7was demonstrated in all(7) serous and 3 out of 4 mucinous adenocarcinoma, and 1 out of10 each gastric and colonic adenocarcinoma. The CK20 positivity was seen in 4 out of 10cases of colonic adenocarcinoma and 3 out of 7 cases of metastatic adenocarcinoma. Allprimary ovarian carcinoma and gastric adenocarcinoma were negative for CK20 except forfocal positivity in only 1 ovarian mucinous adenocarcinoma. All types of serous andendometrioid adenocarcinoma were negative for CEA. But, the vast majority of mucinousadenocarcinoma, metastatic adenocarcinoma, gastric and colonic adenocarcinoma were positivefor CEA. The CK18 may not be helpful to differentiate the primay or metastatic carcinomabecause all cases examined were positive for CK18 except for 1 ovarian mucinous carcinoma.Immunostainning for CK7 may be helpful on differential diagnosis of primary andmetastatic ovarian carcinoma, especially mucinous adenocarcinoma and metastatic gastric andcolonic adenocarcinoma. The CK20 may be a useful marker for differential diagosis inprimary and metastatic ovarian carcinomas. The CEA may be of value on differential diagnosisof mucinous and nonmucinous(serous and endomerioid) ovarian carcinomas, and metastaticcolonic adenocarcinoma and endometrioid carcinoma.In conclusion, immunohistochemical study for CEA, CK7, and CK20 may be helpful indifferential diagnosis between primary and metastatic ovarian carcinoma.
