Background: Postoperative thyroid stimulating hormone (TSH) suppression therapy is recommended for patients with intermediate- and high-risk differentiated thyroid cancer to prevent the recurrence of thyroid cancer. With the recent increase in small thyroid cancer cases, the extent of resection during surgery has generally decreased. Therefore, questions have been raised about the efficacy and long-term side effects of TSH suppression therapy in patients who have undergone a lobectomy. Methods: This is a multicenter, prospective, randomized, controlled clinical trial in which 2,986 patients with papillary thyroid cancer are randomized into a high-TSH group (intervention) and a low-TSH group (control) after having undergone a lobectomy. The principle of treatment includes a TSH-lowering regimen aimed at TSH levels between 0.3 and 1.99 μIU/mL in the low-TSH group. The high-TSH group targets TSH levels between 2.0 and 7.99 μIU/mL. The dose of levothyroxine will be adjusted at each visit to maintain the target TSH level. The primary outcome is recurrence-free survival, as assessed by neck ultrasound every 6 to 12 months. Secondary endpoints include disease-free survival, overall survival, success rate in reaching the TSH target range, the proportion of patients with major cardiovascular diseases or bone metabolic disease, the quality of life, and medical costs. The follow-up period is 5 years. Conclusion The results of this trial will contribute to establishing the optimal indication for TSH suppression therapy in low-risk papillary thyroid cancer patients by evaluating the benefit and harm of lowering TSH levels in terms of recurrence, metabolic complications, costs, and quality of life.

BACKGROUND: The endoscopic transnasal approach is widely used for reconstructing the medial orbital wall by filling it with a silicone sheet or Merocel, but this technique has the disadvantage of retaining the packing for a long time. To overcome this drawback, a method of positioning an absorbable plate in the orbit has been introduced, but there is a risk of defect recurrence after the plate is absorbed. Here, the authors report the results of a novel surgical technique of placing a nonabsorbable titanium mesh with porous polyethylene into the orbit through the endoscopic transnasal approach. METHODS: Fourteen patients underwent surgery using the endoscopic transnasal approach. Preoperative computed tomography (CT) was used to calculate the size of the bone defect due to the fracture, and the titanium mesh was designed to be shorter than the anteroposterior length of the defect and longer than its height. The titanium mesh was inserted into the orbit under an endoscopic view. The authors then confirmed that the titanium mesh supported the orbital contents by pressing the eyeball and finished the operation. Immediately after surgery, CT results were evaluated. RESULTS: Postoperative CT scans confirmed that the titanium mesh was well-inserted and in the correct position. All patients were discharged without any complications. CONCLUSIONS: We obtained satisfactory results by inserting a titanium mesh with porous polyethylene into the orbit via the transnasal approach endoscopically.

OBJECTIVE: To evaluate the effect of hospital-based cardiac rehabilitation (CR) on quality of life (QOL) and physical ability in patients with myocardial infarction (MI). METHODS: Patients with MI who were referred to the Cardiac Health and Rehabilitation Center 2 weeks after percutaneous coronary intervention were divided into CR and non-CR groups. The CR group performed supervised exercises 3 times a week for 2 months. QOL assessment, using the 36-item Short-Form Health Survey (SF-36) and physical ability evaluation were performed at the beginning and end of CR. RESULTS: The CR group demonstrated statistically significant improvements in physical functioning (PF), physical role functioning (RP), bodily pain (BP), general health perceptions (GH), vitality (VT), social role functioning (SF), emotional role functioning (RE), mental health (MH), physical component summary (PCS), and mental component summary (MCS). The non-CR group showed improvement in RP. Secondary outcomes, including resting heart rate (RHR), maximal oxygen consumption (VO(2max)), metabolic equivalent of task (MET), maximal exercise time (ET(max)), stage 3 Borg rating of perceived exertion (3RPE), maximal Borg rating of perceived exertion (RPEmax), and stage 3 rate pressure product (3RPP), improved in the CR group. The non-CR group showed improvements in VO(2max), MET, ET(max), and 3RPE. There were significant differences in improvements in PF, RP, BP, VT, SF, MH, MCS, RHR, VO(2max), MET, ET(max), 3RPE, and 3RPP between the two groups. CONCLUSION: Male patients with MI demonstrated improvements in QOL and physical ability following hospital-based CR; the impact on the mental component was greater than that on the physical component.

Some biological effects of Red Liriope platyphylla (RLP) on various chronic diseases including Alzheimer's disease, diabetes and obesity were suggested after a report of the production from Liriope platyphylla (L. platyphylla, LP) roots using a steaming process. To examine the beneficial effects of ethanol extracts RLP (EEtRLP) on the vascular dysfunction of hypertension, alterations in key factors related to vascular regulation and antioxidant conditions were investigated in spontaneously hypertensive rats (SHR) after EEtRLP treatment for 2 weeks. High levels of 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity were detected in 500 or 1,000 mg/mL EEtRLP. Although no significant improvement of systolic blood pressure or aortic wall thickness were observed in the EEtRLP treated group, the expression level of angiotensin converting enzyme (ACE) and ACE2 increased significantly after EEtRLP treatment. Moreover, the concentration of aldosterone and K ion in serum rapidly recovered in the EEtRLP treated group relative to the vehicle treated group. Furthermore, the endothelial nitric oxide synthase (eNOS) expression and superoxide dismutase (SOD) activity were significantly increased in the EEtRLP treated group relative to the vehicle treated group, while the level of malondialdehyde (MDA) and NOx in the serum of the same group were recovered to the level of Wistar Kyoto (WKY) rats. Overall, the results presented herein provide novel evidence that EEtRLP treatment may improve vascular dysfunction in the aorta of the SHR through up regulation of the antioxidant state and down regulation of aldosterone and K ion concentration. These results also suggest that EEtRLP may be a potential candidate for treatment of various chronic diseases showing vascular dysfunction.

BACKGROUND: Cognitive intervention (CI) is a nonpharmacological approach used to compensate for cognitive impairment. It is categorized into cognitive training, cognitive stimulation and cognitive rehabilitation. Several studies showed that CI could induce cognitive enhancement and reduction of risk for future cognitive decline in patients with brain injury. We investigated effects of CI on cognitive functions and brain glucose metabolism based on serial cognitive assessments and [18F]-Fluorodexoxyglucose positron emission tomography (FDG-PET) in a patient with carbon monoxide (CO) intoxication. METHODS: A 40-year-old man presented with memory impairment and abnormal behaviors such as apathy, indifference, and perseveration 2-month after CO intoxication. Brain magnetic resonance image (MRI) demonstrated high signal changes in the bilateral basal ganglia, hippocampus and the subcortical white matter on T2 weighted images. FDG-PET also showed glucose hypometabolism in the bilateral hippocampus, basal ganglia, and the subcortical white matter. A detailed neuropsychological evaluation revealed multiple cognitive impairments in memory, language and frontal functions. He received twice a week sessions of 60-minute group-based cognitive intervention for 12 weeks. Several neuropsychological examinations and FDG-PETs were conducted at baseline and after CI. RESULTS: After CI, he showed improvements in memory and frontal functions compared with baseline performances. These cognitive improvements persisted by the 7-month follow-up. The extent of glucose hypometabolism was decreased 1-month after CI, however increased 8-month after CI. CONCLUSIONS: This case study suggested that CI could enhance cognitive functions and improve glucose metabolism in a patient with CO intoxication. Also, the effects of CI on cognitive functions seem to be last at least 7-month after training.

OBJECTIVES: The aim of this retrospective study was whether serum Tg predicts malignancy in follicular or Hurthle-cell neoplasms on fine needle aspiration. METHODS: A chart review of 111 patients (90 females, 21 males; mean age 46.8 +/- 11.9 years) with follicular or Hurthle-cell neoplasms on fine needle aspiration, who were surgically treated between Sep. 2001 and Sep. 2011, was performed. Predictive factors for malignancy were identified by the chi-squared test and multivariate logistic regression. RESULTS: There were no differences between 41 malignant and 70 benign lesions in serum Tg or any of the normalized indexes. Receiver-operator characteristic analysis revealed no cut-off value. Lesions with serum Tg levels greater than 500 g/L had no significant difference. And also there were no independent predictors of malignancy by multivariate logistic regression. CONCLUSIONS: In this study, the author found that serum Tg has poor accuracy for predicting malignancy in follicular or Hurthle cell neoplasms on fine needle aspiration.

Imatinib mesylate is a targeted therapy that acts by inhibiting tyrosine kinase of the bcr-abl fusion oncoprotein, which is specific to chronic myeloid leukemia (CML), and the c-transmembrane receptor, which is specific to gastrointestinal stromal tumors. Interstitial pneumonitis is a rare adverse event of imatinib therapy. It is clinically difficult to distinguish from infectious pneumonia, which can frequently occur due to the underlying disease. The standard treatment for imatinib-induced pneumonitis is to discontinue the medication and optionally administer corticosteroids. However, there are a few cases of successful retrial with imatinib. We describe a case of successful rechallenge of imatinib in a patient with imatinib-induced interstitial pneumonitis and CML without a recurrence of the underlying disease after 3 months of follow-up.

Idiopathic chronic ulcerative enteritis (ICUE) is a rare disease with a mortality rate exceeding 75%, which manifests as an ulceration of the small bowel in the absence of a recognizable cause. It is diagnosed by biopsy. A 31-year-old man who had a 10-year history of recurrent episodes of abdominal pain was admitted with a 10-day occurrence of abdominal pain and fever. Upper endoscopy showed multiple active ulcers from duodenal second to distal portion. Colonoscopy revealed diffuse ulcerations at the terminal ileum. Colonic findings were normal. The patient was treated with intravenous antibiotics, systemic steroids, and total parenteral nutrition in the intensive care unit. Ten days after admission, the patient fell into shock due to massive hematochezia and underwent an emergency surgical resection, which revealed Meckel's diverticulum. Bleeding was uncontrolled and the following day surgical resection and intraoperative endoscopy of the highly involved jejunum revealed severe ulcerative bleeding. Microscopic examination revealed ulcerations with pseudopolyps and granulation tissue and no evidence of vasculitis, suggestive of ICUE.

BACKGROUND: Rapidly progressive glomerulonephritis (RPGN) is microscopically characterized by formation of crescents in more than 50% of glomeruli observed. The patients usually move on rapidly to renal failure and the prognosis is not favorable. But there was only a few study because of the rarity in incidence. METHODS: We reviewed and analyzed the records of 15 patients diagnosed as crescentic glomerulonephritis (CrGN) by renal biopsy from March 1990 to December 2003. RESULTS: Fifteen out of 1055 biopsy cases were CrGN including 6 (40%) of pauci-immune glomerulonephritis (PIGN) and 9 (60%) of immune complex glomerulonephritis (ICGN). Underlying diseases of PIGN were: unknown 2, Wegener's granulomatosis 2, focal segmental glomerulosclerosis 1, and rectal cancer 1. For ICGN were: IgA nephropathy 3, lupus nephritis class IV 3, Henoch-Schonlein purpura 2, and HBV-associtated membranoproliferative glomerulonephritis type I. The incidence of major manifestation in PIGN vs. ICGN was respectively: hypertension 50% vs. 22.2%, nephrotic syndrome 50% vs. 88.9%, percents of crescents 73.9% vs. 57.3%. The levels of BUN (mg/dL) and serum creatinine (mg/dL) were higher in PIGN as 76.8 +/- 14.3 and 6.6 +/- 1.2 vs. 26.9 +/- 8.9 and 1.6 +/- 0.3 in ICGN. With methylprednisolone pulse, 5 out of 7 patients showed some improvement in their renal function. A case of Wegener's granulomatosis taken oral prednisolone and another case of lupus nephritis given cyclophosphamide pulse also had relatively favorable course. At the end of follow-up, the more crescents they had the higher creatinine level (r=0.711, p<0.01). CONCLUSION: RPGN manifested nephrotic syndrome commonly and many of them progressed to the chronic kidney disease or even developed end stage renal disease. But appropriate immunosuppre- ssive treatment could help to preserve renal function. When considering the proportion of crescentic glomeruli, it was related to the worse prognosis. It is necessary to make an effort to diagnose early and treat vigorously.
