Gyeongsangbuk-do), mercury contents from shark meat distributed in this region have not been assessed yet. Thus, this study aims to identify the hazard by evaluating the mercury contents of the shark meat sold in the traditional market of Gyeongsangbuk-do.METHODS: The shark meat in the form of muscle meat was obtained from 15 traditional markets of Gyeongsangbuk-do in the summer and winter of 2013. Out of 105 samples in total, 49 were collected in the summer and 56 in the winter. The total mercury concentration was measured by the combustion-gold amalgamation method using an automatic mercury analyzer (Milestone DMA-80, Milestone).RESULTS: The average mercury concentration of shark meat was 2.29 ± 1.77 µg/g, ranging between 0.06–8.93 µg/g with a geometric mean of 1.44 µg/g, which is higher than those reported in many countries. The mercury concentration in 77 of 105 shark meat samples exceeded 1 µg/g. Mercury concentration ranged between 0.09–8.93 µg/g (geometric mean: 1.45) in the summer and 0.06–6.73 µg/g (geometric mean: 1.48) in the winter.CONCLUSIONS: Shark meat sold in the market contained a substantial amount of mercury. This suggests that it is difficult to reduce mercury intake by simply strengthening the standard level of mercury concentration in shark meat. Therefore, it is need to communication and awareness programs with consumers about hazardous effects of mercury inherent in shark meat.]]>

Endobiliary radiofrequency ablation (RFA) is a procedure performed widely to induce locoregional tumor control by the transfer of thermal energy to the lesion and subsequent tumor necrosis. A 72-year-old male with a prior history of acute calculous cholangitis and perforated cholecystitis was admitted to the Kyungpook National University Hospital complaining of fever and nausea. He had an indwelling percutaneous transhepatic gallbladder drainage (PTGBD) catheter from the previous episode of perforated cholecystitis. An abdominal CT scan showed marked dilation of both the intrahepatic and extrahepatic bile ducts. Common bile duct cancer was confirmed histologically after an endobiliary biopsy. A surgical resection was considered to be the initial treatment option. During open surgery, multiple metastatic nodules were present in the small bowel mesentery and anterior abdominal wall. Resection of the tumor was not feasible, so endobiliary RFA was performed prior to biliary stenting. Cholecystectomy was required for the removal of the PTGBD catheter, but the surgical procedure could not be performed due to a cystic ductal invasion of the tumor. Instead, chemical ablation of the gallbladder (GB) with pure ethanol was performed to breakdown the GB mucosa. Palliative treatment for a biliary obstruction was achieved successfully using these procedures. In addition, a PTGBD catheter was removed successfully without significant side effects. As a result, an improvement in the patient's quality of life was accomplished.

OBJECTIVE: The mismatch in the demand and supply of emergency medical resources has been a constant issue in Korean emergency departments (EDs). This study analyzed the characteristics and actual utilization of medical bed resources in these EDs. METHODS: The emergency department utilization (EDU) rate was calculated using the Emergency Medical Resource Information System (EMRIS) on the available beds in EDs from April 2014 to January 2015. The EDU rate was analyzed according to the season, day of the week, time of day, and ED type. Furthermore, the ratio between the maximum and minimum EDU rates was also compared between the regions. RESULTS: A total of 14,889,750 data points were included. The EDU rate was relatively high during winter and on Sundays, and was highest between 20:00 and 22:00. The ratio between the maximum and minimum EDU rates according to the time of day was highest in Gyeongbuk (5.4) and lowest in Daegu (1.4). Moreover, the EDU rate according to the ED type was highest in the regional emergency medical center (66.7%). CONCLUSION: Significant differences were observed in the EDU rates according to the season, day of the week, time of the day, region, and ED type. Therefore, EMRIS should allocate resources based on the data on both the hospital and regional characteristics.

In 2016 and 2017, there were earthquakes greater than 5.0 in magnitude on the Korean Peninsula, which has previously been considered an earthquake-free zone. Patients with chronic kidney disease are particularly vulnerable to earthquakes, as the term “renal disaster” suggests. In the event of a major earthquake, patients on hemodialysis face the risk of losing maintenance dialysis due to infrastructure disruption. In this review, we share the experience of an earthquake in Pohang that posed a serious risk to patients on hemodialysis. We review the disaster response system in Japan and propose a disaster preparedness plan with respect to hemodialysis. Korean nephrologists and staff in dialysis facilities should be trained in emergency response to mitigate risk from natural disasters. Dialysis staff should be familiar with the action plan for natural disaster events that disrupt hemodialysis, such as outages and water treatment system failures caused by earthquakes. Patients on hemodialysis also need to be educated about disaster preparedness. In the event of a disaster situation that results in dialysis failure, patients need to know what to do. At the local and national government level, long-term preparations should be made to handle renal disaster and patient safety logistics. Moreover, Korean nephrologists should also be prepared to manage cardiovascular disease and diabetes in disaster situations. Further evaluation and management of social and national disaster preparedness of hemodialysis units to earthquakes in Korea are needed.

PURPOSE: There is limited data on the use of perampanel in children under 12 years of age. We evaluated the efficacy and tolerability of adjunctive perampanel treatment in children under 12 years of age with refractory epilepsy. METHODS: This retrospective observational study was performed in Kyungpook National University Hospital from July 2016 to March 2018. A responder was defined as a patient with ≥50% reduction in monthly seizure frequency compared with the baseline. Adverse events and discontinuation data were obtained to evaluate tolerability. RESULTS: Twenty-two patients (8 males, 14 females) aged 3.1–11.4 years (mean, 8.0±2.5 years) were included in this study. After an average of 9.2 months (range, 0.5–19 months) of follow-up, 15 patients (68%) showed a reduction in seizure frequency, including 5 patients (23%) with seizure freedom. The age at epilepsy onset was significantly lower (P=0.048), and the duration of epilepsy was significantly longer (P=0.019) in responders than in nonresponders. Nine patients (41%) experienced adverse events, including somnolence (23%), respiratory depression (9%), violence (4.5%), and seizure aggravation (4.5%). The most serious adverse event was respiratory depression, which required mechanical ventilation in 2 patients (9%). Eight patients (36%) discontinued perampanel due to lack of efficacy or adverse events. Three out of 4 patients (75%) who discontinued perampanel due to adverse events had an underlying medical condition. CONCLUSION: Perampanel offers a treatment option for refractory epilepsy in children. Adjunctive treatment with perampanel requires special consideration in those with underlying medical conditions to prevent serious adverse events.

Adipsic hypernatremia is a rare disease where patients do not feel thirst even in the increased serum osmotic pressure and results in electrolyte imbalance, severely increased osmotic pressure and neurologic symptoms like nausea, vomiting, and seizures. We report a 12-year-old male patient who had underwent a trans-sphenoidal surgery for craniopharyngioma newly diagnosed with adipsic hypernatremia after having growth hormone replacement for growth hormone deficiency. The patient visited emergency room complaining of generalized weakness, tremor in both legs, and poor oral intake including water after starting growth hormone replacement therapy. Laboratory test revealed serum sodium 168 mmol/L and serum osmolality 329 mOsm/kg, despite the patient didn't feel any thirst at all. We treated him with scheduled water intake of 2.5 L a day with intranasal vasopressin. He admitted to Soonchunhyang University Gumi Hospital and Soonchunhyang University Seoul Hospital for 4 times during the following 8 months and serum sodium level and osmolality was controlled by scheduled water intake combined with intranasal vasopressin treatment. It is still unclear whether growth hormone replacement worked as a trigger of hypernatremia.

PURPOSE: To evaluate the effect of periodontal and prosthodontic therapy on glycated hemoglobin A(HbA1c) level in patients with diabetes. MATERIALS AND METHODS: This is a retrospective study of 70 patients suffering from diabetes who visited the Kyungpook National University Hospital between January 2016 and May 2018. Patients underwent medical evaluation for their routine check-up, which includes laboratory test for HbA1c levels. Among the 70 patients, 35 patients also visited Kyungpook National University Dental Hospital during the same period to receive periodontal and prosthodontic therapy, while the other 35 patients did not receive such therapy. The HbA1c levels were compared before and after periodontal and prosthodontic therapy. Comparisons between groups and within groups were performed using independent t-test. RESULTS: The HbA1c levels in the group who have received periodontal and prosthodontic therapy decreased from 7.2 to 6.7 (P=.001). The HbA1c levels in the control group decreased from 7.2 to 7.1 (P=.580). The difference in changes between the two patient groups was statistically significant (P=.011). CONCLUSION: Periodontal and prosthodontic therapy can be effective on glycemic control in patients with diabetes.

From October 2015 to August 2018, tapeworm proglottids were obtained from 10 patients who were residents of Daegu and Gyeongbuk provinces and had a history of raw beef consumption. Most of them had no overseas travel experience. The gravid proglottids obtained from the 10 cases had 15–20 lateral uterine branches. A part of internal transcribed spacer 1 (ITS1) DNA of the 10 cases, amplified by polymerase chain reaction (PCR) and digested with AleI restriction enzyme, produced the same band pattern of Taenia saginata, which differentiated from T. asiatica and T. solium. Sequences of ITS1 and cytochrome c oxidase subunit 1 (cox1) showed higher homology to T. saginata than to T. asiatica and T. solium. Collectively, these 10 cases were identified as T. saginata human infections. As taeniasis is one of the important parasitic diseases in humans, it is necessary to maintain hygienic conditions during livestock farming to avoid public health concerns.

The infection status of Clinostomum complanatum metacercariae (CcMc) was broadly surveyed in fishes from water systems of Nakdong-gang (River) in the Republic of Korea (Korea) for 5 years. All 4,468 fishes collected were individually examined by the artificial digestion methods. No CcMc were detected in fishes from Naeseongcheon in Yecheon-gun, Gigyecheon in Gyeongju-si, Gyeongsangbuk-do, and Hamancheon in Haman-gun, Gyeongsangnam-do. In fishes from Wicheon in Gunwi-gun, Gyeongsangbuk-do, CcMc were detected in 180 (15.4%) out of 1,168 fishes and their intensity was 5.8 per fish infected. The prevalences with CcMc in positive fish species from 3 other surveyed areas, i.e., Banbyeoncheon in Yeongyang-gun, Nakdong-gang in Sangju-si and Hoecheon in Goryeong-gun, in Gyeongsangbuk-do were 19.3%, 33.3%, and 19.0% and their intensities were 1.5, 17.6, and 2.6 per fish infected respectively. In fishes from Yangcheon in Sancheong-gun, Gyeongsangnam-do, CcMc were detected in 811 (45.6%) out of 1,779 fishes examined and their intensity was 9.8 per fish infected. The prevalence was most high in Squalidus spp. (97.7%) and followed by acheilognathinid fish (66.8%), Pungtungia herzi (52.0%), rasborinid fish (39.6%) and Hemibarbus spp. (25.9%) from Yangcheon. The intensity was also most high in Squalidus spp. (27.0). The endemicity with CcMc was very low in fishes from water systems of Nakdong-gang in the east coast of Korea. Conclusively, it is confirmed that various fish species act as the second intermediate hosts of C. complanatum, and the endemicities of CcMc are more or less different by the fish species and group from Yangcheon, in Sancheong-gun, Gyeongsangnam-do, Korea.

BACKGROUND: The role of allogeneic hematopoietic cell transplantation (allo-HCT) compared with consolidation chemotherapy alone in intermediate-risk acute myeloid leukemia (AML) patients with wild-type nucleophosmin/negative or a low level of Fms related tyrosine kinase 3 internal tandem duplication (NPM1(wt)/FLT3-ITD(neg/low)) has not yet been elucidated. METHODS: In this study, we retrospectively investigated 88 patients newly diagnosed with AML who received intensive induction chemotherapy at Kyungpook National University Hospital from March 2015 to July 2017. The selection criteria included the presence of results on genetic abnormalities including NPM1 and FLT3-ITD. RESULTS: According to the European LeukemiaNet (ELN) risk classification, 25 patients (28%) were categorized as favorable, 44 (50%) as intermediate, and 19 (22%) as adverse risk. Among the intermediate-risk patients, 40 were identified as NPM1 wt/FLT3-ITDneg/low. Among the patients with NPM1(wt)/FLT3-ITD(neg/low), complete remission (CR) was achieved in 26 patients out of 40 (65%). One-year overall survival (OS) rate was 100% in the favorable-risk group and 87.9% in the NPM1(wt)/FLT3-ITD(neg/low) group (P=0.233). Among the intermediate-risk NPM1(wt)/FLT3-ITD(neg/low) patients, there was no survival benefit with allo-HCT (N=19) compared to consolidation chemotherapy (N=21; P=0.372). In the multivariate analysis, the ELN risk group [hazard ratio (HR), 6.36; P=0.019] and the achievement of CR (HR, 2.95; P=0.017) were both identified as factors affecting OS of patients with newly diagnosed AML. CONCLUSION: Among the AML patients, intermediate-risk NPM1(wt)/FLT3-ITD(neg/low) patients and favorable-risk patients showed similar OS rates. Our results suggested that allo-HCT might have limited clinical benefit for the intermediate-risk NPM1(wt)/FLT3-ITD(neg/low) patients. Well controlled studies are needed to confirm the current results.
