Pancreatic metastasis from papillary thyroid cancer (PTC) is extremely rare; only 18 cases have been reported in the literature. However, several reviews have highlighted similar characteristics between metastatic and primary pancreatic tumors. The patient was a 51-year-old male with a history of total thyroidectomy, modified radical neck dissection, and radioactive iodine ablation for PTC in 2014. Nodules suspected of metastasis were found in both lungs on chest computed tomography (CT). However, after 6 months, a follow-up chest CT showed no increase in size; thus, a follow-up observation was planned. Six years after his initial diagnosis, abdominal CT and pancreas magnetic resonance imaging revealed a 4.7 cm cystic mass with a 2.5 cm enhancing mural nodule in the pancreas tail. We diagnosed the pancreatic lesion as either metastatic cancer or primary pancreas cancer. The patient underwent distal pancreato-splenectomy. After surgery, the pathological report revealed that the mass was metastatic PTC. Pancreatic metastasis from PTC indicates an advanced tumor stage and poor prognosis. However, pancreatectomy can increase the survival rate when the lesion is completely resectable. Therefore, surgical resection should be considered as a treatment for pancreatic metastasis from PTC.

OBJECTIVE: We designed a nationwide study with limited exclusion criteria to investigate the prevalence of metabolic syndrome (MetS) in Korea and its relationship with antipsychotic medications. METHODS: This multicenter, cross-sectional, and observational study included patients diagnosed with schizophrenia or schizoaffective disorder. Sixteen hospitals enrolled 845 patients aged 18 to 65 years prescribed any antipsychotic medication between August 2011 and August 2013. MetS was diagnosed using the criteria of the modified Adult Treatment Panel III of the National Cholesterol Education Program with the Korean abdominal obesity definition (waist circumference ≥85 cm in women, ≥90 cm in men). RESULTS: The prevalence of MetS in all patients was 36.5% and was significantly higher in men than women (men, 40.8%; women, 32.2%) and was significantly correlated with age [odds ratio (OR) 1.02] and duration of illness (OR 1.03). The prevalence of MetS across antipsychotic drugs in the major monotherapy group was as follows: 18.8% for quetiapine, 22.0% for aripiprazole, 33.3% for both amisulpride and paliperidone, 34.0% for olanzapine, 35% for risperidone, 39.4% for haloperidol, and 44.7% for clozapine. CONCLUSION: The prevalence of MetS is very high in patients with schizophrenia or schizoaffective disorder. Screening and monitoring of MetS is also strongly recommended.

PURPOSE: This study was performed in order to determine the changes over time in preventable and potentially preventable traumatic death rates, and to assess the factors that affected the deaths of trauma patients which occurred in Korean pre-hospital and hospital settings. METHODS: All trauma deaths occurring either in the emergency department (ED) or after admission at twenty Korean hospitals between August 2009 and July 2010 were retrospectively analyzed. The deaths were initially reviewed by a team of multidisciplinary specialists and classified into non-preventable, potentially preventable, and preventable deaths. Only preventable and potentially preventable deaths were the subject of our analysis. Structured data extraction included patient demographics, vital signs, injury severity, probability of survival, preventability of mortality, reported errors in the evaluation and management of the patient, and classification of error types (system, judgment, knowledge). RESULTS: During the study period, 446 trauma victims died in the ED or within 7 days after admission. The mean age was 52 years, 74.1% were men and the mean time from injury to death was 35.6 hours. The most common cause of death was head injury (44.7%) followed by hemorrhage (30.8%) and multi-organ failure (8.0%). The rates of preventable/potentially preventable deaths were 35.2% overall and 29.8% when limited to patients surviving to admission. Of all death classifications, 31.2% were potentially preventable and 4.0% were preventable. Errors leading to preventable death occurred in the emergency department (51.2%), pre-hospital setting (30.3%) and during inter-hospital transfer (60.8%). Most errors were related to clinical management (48.4%) and structural problems in the emergency medical system (36.5%). CONCLUSION: The preventable death rates for Korean trauma victims were higher than those found in other developed countries, possibly due to poorly established emergency medical systems for trauma victims in pre-hospital and hospital settings. A system wide approach based on the emergency medical system and well-developed in-hospital trauma teams should be adopted in order to improve the quality of care of trauma victims in Korea.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality throughout the world and is the only major disease that is continuing to increase in both prevalence and mortality. The second Korean National Health and Nutrition Survey revealed that the prevalence of COPD in Korean subjects aged > or =45 years was 17.2% in 2001. Further surveys on the prevalence of COPD were not available until 2007. Here, we report the prevalence of spirometrically detected COPD in Korea, using data from the fourth Korean National Health and Nutrition Survey (KNHANES IV) which was conducted in 2007~2009. METHODS: Based on the Korean Statistical Office census that used nationwide stratified random sampling, 10,523 subjects aged > or =40 years underwent spirometry. Place of residence, levels of education, income, and smoking status, as well as other results from a COPD survey questionnaire were also assessed. RESULTS: The prevalence of COPD (defined as forced expiratory volume in 1 sec/forced vital capacity <0.7 in subjects aged > or =40 years) was 12.9% (men, 18.7%; women, 7.5%). In total, 96.5% of patients with COPD had mild-to-moderate disease; only 2.5% had been diagnosed by physicians, and only 1.7% had been treated. The independent risk factors for COPD were smoking, advanced age, and male gender. CONCLUSION: The prevalence of COPD was 12.9% in the KNHANES IV data. Most patients with COPD were undiagnosed and untreated. Based on these results, a strategy for early COPD intervention is warranted in high risk subjects.

BACKGROUND: This study compared the bronchodilator efficacy and safety of tiotropium inhalation capsules (18microgram once daily) with a ipratropium metered dose inhaler (2 puffs of 20microgram q.i.d.) in patients with chronic obstructive pulmonary disease (COPD). METHOD: After the initial screening assessment and a two-week run-in period, patients received either tiotropium 18microgram once daily or ipratropium 40microgram four times daily over a period of 4 weeks in a double blind, double dummy, parallel group study. The outcome measures were the lung function, the daily records of the peak expiratory flow rate (PEFR), the patients' questionnaire, and the use of concomitant salbutamol. The forced expiratory volume in one second (FEV1) and the forced vital capacity (FVC) were measured 5 minutes before inhalation, and 0.5, 1, 2 and 3 hours after inhaling the study drug on days 0, 14 and 28. RESULT: In 16 centers, 134 patients with a mean (SD) age of 66 (7) years and a predicted FEV1 of 42 (12)% were analyzed. The trough FEV1 response was significantly higher in the tiotropium group than in the ipratropium group after a four-week treatment period. The weekly mean morning PEFR of the tiotropium group was consistently higher than that of the ipratropium group during the 4-week treatment period with differences ranging from 12.52 to 13.88 l/min, which were statistically significant. Tiotropium was well tolerated by the COPD patients during the 4-week treatment period and had a similar safety profile to ipratropium. CONCLUSION: This study shows that tiotropium administrated once daily has a superior bronchodilator effect with a similar safety profile in treating COPD patients compared with ipratropium, inhaled four times daily.

Because the Korean nose has a flat dorsum and depressed tip, tip projection procedure has frequently been performed as an ancillary procedure of dorsal augmentation. Although various materials have been used for tip plasty, an ideal technique has not yet been described. The authors performed classic augmentation rhinoplasty using a silicone implant to correct flat dorsum. Alloderm(R)(Life Cell Corporation, the Woodlands, Texas), acellular human dermis, was used for soft and smooth projection of the nasal tip. From January of 2000 to August of 2003, 20 patients underwent this procedure in Department of Plastic and Reconstructive Surgery. The patients were followed up for 2 to 26 months. Postoperative course was uneventful. Although partial graft resorption was noted in 3 patients, long-term follow-up showed good results. Alloderm(R) usage for tip plasty allows natural contour of the nasal tip, decreases donor site morbidity, and obviates time consuming procedures for graft harvesting. In conclusion, Alloderm(R) graft could be an appropriate alternative in tip projection procedure.

BACKGROUND: Hydatidiform mole (H-mole) is characterized by the neoplastic proliferation of trophoblasts. Only 1~10% of patients with partial H-mole will develop a trophoblastic tumor, but 18~29% of those with complete H-mole will develop a persistent trophoblastic tumor. Therefore, the early diagnosis and monitoring after operation of an H-mole disease are very important. Recently, the pregnancy associated plasma protein-A (PAPP-A) was proved to have a similar role as that of IGF binding protein-4 (IGFBP-4) protease, which has shown an increasing function in fetal growth and development by degradation of IGFBP-4 and an increase in IGF in the serum during pregnancy. Our hypothesis is "the H-mole, which shows placental hyperplasia will also have an IGFBP-4 protease activity, which may be used as in the early diagnosis and monitoring of H-mole disease". METHODS: Serum samples from 6 non-pregnant, 18 pregnant (5 in the 1st trimester, 10 in the 2nd, and 3 in the 3rd), 12 postpartum women and 3 H-mole patients(2 with complete H-mole and 1with partial H-mole) were collected and measured for the -HCG, IGF and PAPP-A levels and IGFBP-4 protease activities by a IGF-II ligand blot analysis and electrophoresis method. The IGFBP-4 protease activity of the serum during normal pregnancy was compared with that of H-mole disease. RESULTS: The results from the in vitro protease assays using recombinant IGFBP-4 determined that IGFBP-4 proteolysis was significantly increased during the first (56%) and second trimesters (90%), but reached a plateau by the third trimester (94%). In H-mole disease diagnosed 11 weeks after conception, the IGFBP-4 proteolytic activity was 97%, which was nearly the same as at terminal pregnancy. This activity gradually decreased to 75% at 1 week, 58.7% at 2 and 33% at 3 weeks after the operation. The -HCG was also decreased from 490,400 to 123,822.7, 1,352.3, and 128.5 mIU/mL at 1, 2 and 3 weeks after the operation, respectively. The PAPP-A level also gradually decreased from 34.87 to 25.5, 12.0 and 2.7 g/mL 1, 2 and 3 weeks after the operation, respectively. However, the IGF decreased from 238.3 to 172.9 ng/mL 1 week after the operation, but increased to 251.4 and 295 ng/mL at 2 and 3 weeks after the operation, respectively. CONCLUSION: These results demonstrated that the IGFBP-4 protease activity was significantly increased during pregnancy, and was extremely elevated durimg the early stages of H-mole disease, but gradually decreased after removal of molar tissue. Therefore, measuring the IGFBP-4 protease activity may play an important role in the early diagnosis and monitoring of H-mole disease

BACKGROUND: Many studies about unilateral cerebellar infarctions (UCI) have been reported to delineate the clinical findings and stroke mechanisms but have not been studied extensively in acute bilateral cerebellar infarctions (BCI). In order to evaluate the neurological features and mechanisms of BCI, we compared those between BCI and UCI. METHODS: Using diffusion-weighted imaging, we divided 103 patients with acute cerebellar infarctions into two groups: BCI and UCI. Clinical features, outcome and their mechanisms were compared between the groups. RESULTS: Among the 103 patients, 45 patients (44%) had BCI and the remaining 58 patients had UCI. The PICA territory was the most frequently involved site in both groups, and 15 patients were non-territorial infarctions. Clinical symptoms and signs were not different between the groups, however, most patients with decreased mentality had BCI (86%) and also had concomitant lesions outside the cerebellum (72%). Patients with BCI showed poorer prognosis than UCI (modified Rankin score, 1.41 and 2.87 respectively). Other factors included the presence of concomitant lesiona outside the cerebellum, however, mass effect did not affect their prognosis. The main cause of BCI was large artery disease (57%), whereas about half of the patients with UCI (51%) had no demonstrable cause of stroke. CONCLUSIONS: Owing to its poorer outcome and its higher frequency of demonstrable causes of stroke, more intensive work-up, such as vascular study, may be warranted in the patients with acute BCI.

BACKGROUND: It is well known that a lacunar infarction has characteristic clinical features and a relatively good prognosis. However, the significance of lesions in the parent artery of patients with lacunar syndrome as regard to the prognosis remains unsettled. METHODS: Using the data of consecutive patients with their first ischemic stroke and were followed longer than 1 year, were divided the patients by their clinical features and the results of the work-up was as follows; (1) mismatching [MM] group; lacunar syndrome and the presence of parent arterial lesion, (2) large artery artherosclerosis [LAD]; non-lacunar syndrome and the presence of parent arterial lesion, (3) no determined etiology [NE]; non-lacunar syndrome without parent arterial lesion, and (4) small artery disease [SAD]; lacunar syndrome without parent arterial lesion. Patients with a potential source of embolism were excluded from this study. The prognosis and recurrence rate of patients with the MM group were compared with those of other groups. RESULTS: A total of 176 patients were included; 56 LAD, 62 SAD, 22 MM and 36 NE groups. An unstable hospital course was more frequently found in LAD than in the other groups. The recurrence rate of the MM group (23%) was significantly higher than that of SAD (2%), but was similar to that of patients with non-lacunar syndrome (LAD 16%, NE 28%). CONCLUSIONS: Among patients with lacunar syndrome, the prognosis of those with parent arterial lesions was different from those without lesions. Therefore, a systematic work up of the stroke mechanism may be important in patients with lacunar syndrome.
