BACKGROUND: Follicular thyroid carcinoma (FTC) is the second most common thyroid malignancy and its differential diagnosis includes follicular adenoma (FA) and adenomatous goiter (AG). Several ancillary markers have been suggested to aid in the diagnosis of FTC, but the successful use of these methods still needs to be validated. METHODS: In the present study, we verified the immunoexpression of HMGA2, CEACAM6, survivin, and SFN/14-3-3 delta in lesions including 41 AGs, 72 FAs, and 79 FTCs. We evaluated their diagnostic usefulness, combined with galectin 3, Hector Battifora mesothelial 1 (HBME1), cytokeratin 19, and cyclin D1, in diagnosing FTC. RESULTS: The expressions of HBME1 (65.8%) and HMGA2 (55.7%) were significantly higher in FTCs than in FAs and AGs (p<.001 and p=.005, respectively). HBME1 was the only marker that was more frequently expressed in FTCs than in FAs (p=.021) and it was more frequently expressed in follicular neoplasms than in AGs (p<.001). Among the novel markers, the combination of HMGA2 and HBME1 showed the highest sensitivity (72.2%) and specificity (76.1%) for diagnosing FTC. CEACAM6, survivin, and SFN/14-3-3 delta were barely expressed in most cases. CONCLUSIONS: Our present results show that only HMGA2 can be beneficial in differentiating FTC using the novel markers.

A case is reported of a man with malignant fibrous histiocytoma (MFH) in right thigh who developed streptococcal toxic shock syndrome (STSS) during postoperative radiotherapy. Before radiotherapy, a patient complained wax and wane lymphedema following wide excision of tumor mass which was confirmed as MFH. He took some nonsteroidal antiinflammatory drug (NSAID) for about one month. He suffered preexisting hepatitis C virus (HCV) infection, diabetes and well-controlled hypertension. The patient received conventional radiotherapy to right thigh with a total dose of 32.4 Gy at 1.8 Gy per day. At last radiotherapy fraction, cutaneous erythematous inflammation was suddenly developed at his affected thigh. At that time, he also complained of oliguria, fever and chills. The patient was consulted to internal medicine for adequate evaluation and management. The patient was diagnosed as suggested septic shock and admitted without delay. At admission, he showed hypotension, oliguria, constipation, abnormal renal and liver function. As a result of blood culture, Streptococcus pyogenes was detected. The patient was diagnosed to STSS. He was treated with adequate intravenous antibiotics and fluid support. STSS is one of oncologic emergencies and requires immediate medical intervention to prevent loss of life. In this patient, underlying HCV infection, postoperative lymphedema, prolonged NSAID medication, and radiotherapy may have been multiple precipitating factors of STSS.

PURPOSE: To report a patient with asteroid hyalosis, which induced reduction of the visual acuity after cataract surgery.CASE SUMMARY: A 79-year-old female with no ophthalmic history visited our clinic with decreased vision. Her best-corrected visual acuity in both eyes was 20/100 in the right eye and 20/60 in the left eye. She had senile cataract in both eyes, and asteroid hyalosis in the left eye. After cataract surgery, her visual acuity in the left eye decreased to finger count. There were no specific findings that could have caused the visual disturbance, except dense asteroid bodies on fundus examination. After removal of the asteroid bodies by vitrectomy, the best-corrected visual acuity of the left eye recovered to 20/20.CONCLUSIONS: In patients with asteroid hyalosis, it is possible that decreased vision may be affected by changes of asteroid body properties in the vitreous gel after cataract surgery. The vision should improve after vitreous surgery.

PURPOSE: The purpose of this pilot study was to investigate the effects of mechanical interventions for deep vein thrombosis (DVT) prophylaxis in surgical intensive care unit (SICU) patients. METHODS: The participants were assigned to the intermittent pneumatic compression (IPC) and graduated compression stocking (GCS) intervention. Patients who met the criteria were selected for comparison from our previous study. Data for 140 patients were included in the final analysis. RESULTS: The mean age was 57.5 (+/-15.7) and 61.4% were men. About forty-seven percent of the participants were 61 years or over. In the second duplex scan, 3, 2 and 1 critically ill patients developed deep vein thrombosis in the control, GCS, and IPC groups, respectively. Incidences of DVT were 6.0%, 5.0%, and 2.0% for the control, GCS, and IPC groups, respectively. This difference was not significant. Relative risks of no intervention were 3.0 and 1.2 compared with IPC and GCS application. There were no significantly different variables among the three groups before the intervention except for diagnosis on admission. CONCLUSION: Although it may difficult to conclude that mechanical prophylaxis effectively prevents DVT among SICU patients because there was no statistical significance in this study, but incidence rates among the three groups differed greatly. The findings reveal that further study should be conducted with larger samples and randomized controlled trial for SICU patients.

PURPOSE: Novel influenza H1N1 A virus developed pandemic infection, and patients requiring hospitalization have rapidly increased because of severe clinical symptoms and signs. We describe the clinical features of hospitalized pediatric patients with novel influenza virus infection. METHODS: We reviewed the medical charts of 128 pediatric patients under the age of 16 who were hospitalized in Dongguk University Ilsan Hospital between September 2009 and February 2010. We compared the clinical features of the pneumonia and non-pneumonia groups of patients, and analyzed clinical difference according to M. pneumoniae coinfection and severity of pneumonia. RESULTS: The male to female sex ratio of the subjects was 2.2:1, and the average age was 6.2 years. Sixty-five patients (50.8%) had pneumonia and their average age was 6.7 years. Variables including duration of admission, total WBC counts, neutrophil percentage and CRP were significantly different between the 2 groups, however, the other variables were not. The number of patients diagnosed with severe pneumonia was 20 (30.8%). M. pneumoniae coinfection occurred in 24.6% of patients in the pneumonia group, however, it did not influence the severity of pneumonia. Underlying asthma was more significantly associated with severe pneumonia than with mild pneumonia. There was no death case. CONCLUSION: In this study, 2009 novel influenza infection was more prevalent in school-age boys. M. pneumoniae coinfection occurred frequently, however, it did not seem to influence disease severity. Patients with underlying asthma tend to develop severe pneumonia more frequently.

BACKGROUND: For effective postoperative antiemetic management in pediatric moyamoya disease patients receiving fentanyl based postoperative analgesia, a multimodal approach has been recommended. The uncertain efficacy of ondansetron for pediatric neurosurgical patients or the possible antiemetic effect of small dose of propofol motivated us to evaluate the preventive effect of a subhypnotic dose of propofol combined with dexamethasone on postoperative vomiting (POV), especially during immediate postoperative periods. METHODS: In a prospective observer-blind randomized controlled study, we compared dexamethasone 0.15 mg/kg alone (Group D) with dexamethasone combined with propofol of 0.5 mg/kg (Group DP) in 60 pediatric patients, aged 4-17 years, who underwent indirect bypass surgery and received fentanyl-based postoperative analgesia. Occurrence of vomiting and pain score (Wong-Baker facial score) and requirement of rescue analgesic and antiemetic were continually measured (0-2, 2-6, 6-12 and 12-24 postoperative hours). For statistical analysis, in addition to the Fisher's exact test, a generalized linear mixed model (GLMM) and the linear mixed model (LMM) for repeated measures were used for vomiting and pain scores, respectively. RESULTS: There was no statistical significance of POV incidence, requirement of rescue analgesic and pain score between the two groups at any measured intervals. The incidence of POV was 53.3% during 24 hours in both groups, and was especially 6.7% and 13.3% (P = 0.671) during 0-2 hr and 16.7% and 23.3% (P = 0.748) during 2-6 hr in group D and group DP, respectively. CONCLUSIONS: A small dose of propofol combined with dexamethasone appears ineffective to preventing POV in pediatric moyamoya patients receiving continuous fentanyl infusion.

PURPOSE: The study was done to define complementary and alternative medicine (CAM) use among primary brain tumor patients and factors influencing use. METHODS: The study was conducted with convenience sampling in 5 neuro-oncology centers in Seoul and Gyeonggi Province. Data were collected using a 25-item questionnaire developed by the researchers. RESULTS: Of 250 patients approached, 231 (92.4%) agreed to participate. Overall, 26.8% of the respondents used CAM and the average cost for CAM use was 300,000 KRW. More than 72% of CAM users did not disclose CAM use to their health care professionals. The most frequently used therapy was natural products including mushrooms. Logistic regression analysis revealed that an education level of university or higher (OR=2.92, 95% CI=1.56-5.44, p=.001), unemployment (OR=1.99, 95% CI=1.04-3.80, p=.037), and WHO grade III & IV tumors (OR=2.18, 95% CI=1.07-4.72, p=.048) were significant factors influencing CAM use. CONCLUSION: Three out of ten brain tumor patients spend substantial sum of money for CAM. In these situations, health care professionals should be aware of this phenomenon and provide adequate information and consultation to the patients.

BACKGROUND: Because of its efficacy and safety, polyethylene glycol (PEG) is generally used to prepare for colonoscopy. However, the side effects of PEG, including nausea, vomiting, abdominal discomfort, pain, and general weakness, tend to decrease patient compliance and satisfaction. The aim of this study is to investigate the efficacy and safety of PEG with 0.1 mg ramosetron on colonoscopy patients who had difficulty taking PEG due to side effects or large volume.METHODS: From January to August in 2012, 28 patients who visited Yeungnam University hospital for a colonoscopy were prospectively enrolled. All enrolled patients were previous history underwent colonoscopy using PEG only in our hospital. The efficacy and safety of ramosetron were assessed through the use of a questionnaire, and compared previous bowel preparation.RESULTS: Compared to previous examination, the patients using the ramosetron reported less nausea, vomiting, abdominal discomfort, and abdominal pain, as well as a higher degree of compliance and satisfaction of the patient. There were no side effects reported with the use of ramosetron. However, overall bowel preparation quality was not better than the previous examination.CONCLUSION: In case of the use of ramosetron in combination with PEG for bowel preparation, patients experienced a higher rate of compliance and tolerance. Looking forward, ramosetron may become an option of pretreatment for bowel preparation.
