Purpose: The purpose of this study is to analyze the clinical results of patients with basicervical fractureundergoing cephalomedullary nailing (CMN) with an additional cannulated screw fixation compared to only performing CMN. We hypothesized that a difference may exist in the clinical outcomes if an ad-ditional screw is fixed with CMN compared to only performing CMN in basicervical fracture. Materials and Methods: A total of 28 consecutive patients who underwent CMN for basicervical fracture were included. In 9 cases, only CMN was conducted, and in 19 cases, an additional cannulated screw fixation was performed with CMN. Bone union, sliding distance, reduction status, and fixation failure were evaluated by postoperative radiography, and ambulatory ability was evaluated by functional results. These findings were compared between a group of CMN and a group of CMN with an additional cannulated screw. Results: There were 4 males and 24 females with a mean age of 84 years (range, 69–100 years). No significant difference was found in postoperative reduction, tip-apex distance, bone union, and walking function recovery after surgery between the two groups, but in the sliding distance of the lag screw, the CMN group demonstrated more sliding (6.2 mm [range, 2.5–13.4 mm] vs 3.5 mm [range, 0.1– 9.2 mm]; p=0.045). Among the two groups, only one case of fixation failure at the postoperative four months was observed in the CMN group (p=0.321), and hemiarthroplasty with nail construct removal was performed. Conclusion CMN with additional cannulated screw fixation is a safe and reliable surgical option in basicervical fracture. It provided favorable clinical outcomes and may be a good alternative for treating basicervical fracture.

Growth hormone (GH) and thyroid stimulating hormone (TSH)-secreting pituitary adenomas are very rare and they account for only 0.5% for all pituitary adenomas. These adenomas are usually treated with surgery, but this surgery is not easy because the tumor is usually huge and invasive. We reported here on a case of a GH-TSH-secreting adenoma in a 23-year-old male patient who was initially treated with octreotide LAR. He presented with symptoms of headache, palpitation and a visual defect that he had for the 3 months. He had hypertrophy of the frontal bone and enlargement of both the hands and feet. The visual field test showed bitemporal hemianopsia. The laboratory examinations showed high serum levels of free T4, TSH and free alpha-subunit. Additionally, the serum levels of GH and insulin-like growth factor-I (IGF-I) were increased. GH was not suppressed below 1microg/L by an oral 75g glucose loading test, and TSH was not stimulated by thyrotropin-releasing hormone (TRH). Because sellar MRI showed invasive macroadenoma encasing the vessels, we initially tried octreotide LAR for treatment. A year later, the IGF-I and thyroid function tests were normalized and the size of the tumor was reduced with cystic change. The symptoms of palpitation and headache were improved without a change of the visual field defect.

BACKGROUND: Chemerin is a novel adipokine that is associated with inflammation and adipogenesis. However, it remains unclear whether chemerin is involved in patients with cardiovascular disease. We investigated whether the serum chemerin levels of Korean patients with coronary artery disease correlated with specific cardiometabolic parameters. METHODS: In total, 131 patients, all of whom had coronary artery stenosis exceeding 50%, participated in this study. Their serum chemerin levels and cardiometabolic parameters were measured. The serum chemerin levels of two groups of patients were compared; those with one stenotic vessel (n=68) and those with multiple stenotic vessels, including left main coronary artery disease (n=63). RESULTS: Serum chemerin levels correlated positively with the degree of coronary artery stenosis and fasting glucose, triglyceride, total cholesterol, low density lipoprotein cholesterol, and high sensitive C-reactive protein levels. The group with multiple stenotic vessels, including left main disease, had higher chemerin levels than the group with one stenotic vessel (t=-2.129, P=0.035). Multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease (odds ratio, 1.018; confidence interval, 0.997 to 1.040; P=0.091). CONCLUSION: Serum chemerin levels have a significant correlation with several cardiometabolic risk factors and the degree of coronary artery stenosis in Korean patients with coronary artery disease. However, multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease. Additional investigations are necessary to fully elucidate the role of chemerin in cardiovascular disease.

BACKGROUND: The highly developed endoplasmic reticulum (ER) structure in pancreatic beta cells is heavily involved in insulin biosynthesis. Thus, any perturbation in ER function inevitably impacts insulin biosynthesis. Recent studies showed that the expression of tribbles-related protein 3 (TRB3), a mammalian homolog of Drosophilia tribbles, in various cell types is induced by ER stress. Here, we examined whether ER stress induces TRB3 expression in INS-1 cells and found that TRB3 mediates ER stress-induced suppression of insulin gene expression. METHODS: The effects of tunicamycin and thapsigargin on insulin and TRB3 expression in INS-1 cells were measured by Northern and Western blot analysis, respectively. The effects of adenovirus-mediated overexpression of TRB3 on insulin, PDX-1 and MafA gene expression in INS-1 cells were measured by Northern blot analysis. The effect of TRB3 on insulin promoter was measured by transient transfection study with constructs of human insulin promoter. RESULTS: The treatment of INS-1 cells with tunicamycin and thapsigargin decreased insulin mRNA expression, but increased TRB3 protein expression. Adenovirus-mediated overexpression of TRB3 decreased insulin gene expression in a dose-dependent manner. A transient transfection study showed that TRB3 inhibited insulin promoter activity, suggesting that TRB3 inhibited insulin gene expression at transcriptional level. Adenovirus-mediated overexpression of TRB3 also decreased PDX-1 mRNA expression, but did not influence MafA mRNA expression. CONCLUSIONS: This study showed that ER stress induced TRB3 expression, but decreased both insulin and PDX-1 gene expression in INS-1 cells. Our data suggest that TRB3 plays an important role in ER stress-induced beta cell dysfunction.

BACKGROUND AND AIMS: The objective of this paper is to compare the effectiveness of com-mon bile duct stone extraction by conditions and methods. METHODS: Endoscopic sphinc-terotomies with stone extraction were practiced in 71 patients with common bile duct stones by basket extraction, balloon extraction and mechanical lithotripsy. RESULTS: 1) In 71 patients with CBD stone, sex distribution showed predominence in females (56.3%) and most of the cases were over 60 years old. 2) After sphincterotomy, the overall success rate of the stone extraction was 87.3% (with balloon and basket or mechanical lithotrispy). The removal methods of the stone extractions were varied, but the most commonly used method was basket extraction (50.7%). 3) The complications of sphicterotomy were noted in 10 cases and in 8 cases minor bleeding was stopped with a hypertonic saline epinephrine injection. 4) After the stone extraction, counts and levels of leukocyte, aspartate transami-nase, alanine transaminase, alkaline phosphatase and total bilirubin were significantly improved (p <0.05). 5) Removal methods according to stone size did not show a signifi-cant difference, but the mean size of the stones was different. According to the several methods, the mean diameter of stones were different. The stone size was 1.1 cm in the case of spontaneous removal, 1.4 cm in balloon or basket removal, 1.9 cm in mechanical lithotripsy and 2.0 cm in surgical removal. CONCLUSIONS: Endoscopic stone extraction was effective and safe method with low rate of complications. However there were some significant difficulties in removing large or impacted stones, therefore EHL, ESWL or operation should be considered.

Sunitinib is a tyrosine-kinase inhibitor used to treat metastatic renal cell carcinoma and imatinib-resistant gastrointestinal stromal tumors. Hypothyroidism is a common side effect of sunitinib therapy. Nevertheless, overt thyrotoxicosis induced by destructive thyroiditis after sunitinib treatment is very rare. Here, we report a patient with overt thyrotoxicosis related to sunitinib therapy.

BACKGROUND/AIMS: Fabry disease is an X-linked recessive and progressive disease caused by alpha-galactosidase A (alpha-GaL A) deficiency. We sought to assess the prevalence of unrecognized Fabry disease in dialysis-dependent patients and the efficacy of serum globotriaosylceramide (GL3) screening. METHODS: A total of 480 patients of 1,230 patients among 17 clinics were enrolled. Serum GL3 levels were measured by tandem mass spectrometry. Additionally, we studied the association between increased GL3 levels and cardiovascular disease, cerebrovascular disease, or left ventricular hypertrophy. RESULTS: Twenty-nine patients had elevated serum GL3 levels. The alpha-GaL A activity was determined for the 26 patients with high GL3 levels. The mean alpha-GaL A activity was 64.6 nmol/hr/mg (reference range, 45 to 85), and no patient was identified with decreased alpha-GaL A activity. Among the group with high GL3 levels, 15 women had a alpha-GaL A genetics analysis. No point mutations were discovered among the women with high GL3 levels. No correlation was observed between serum GL3 levels and alpha-GaL A activity; the Pearson correlation coefficient was 0.01352 (p = 0.9478). No significant correlation was observed between increased GL3 levels and the frequency of cardiovascular disease or cerebrovascular disease. CONCLUSIONS: Fabry disease is very rare disease in patients with end-stage renal disease. Serum GL3 measurements as a screening method for Fabry disease showed a high false-positive rate. Thus, serum GL3 levels determined by tandem mass spectrometry may not be useful as a screening method for Fabry disease in patients with end stage renal disease.

PURPOSE: To assess the usefulness of diffusion-weighted MR imaging in patients with intracranial tumors. MATERIALS AND METHODS: Using the single-shot spin echo EPI technique on a 1.5T unit and two gradient steps(b values of 0, 900 s/mm2), diffusion-weighted MR images (DW-MRI) of 76 patients with various intracranial tumors including high-grade glioma (n=20), meningioma (n=15), metastasis(n=14), lymphoma (n=6), low-grade glioma (n=5), schwannoma (n=4), cerebellar hemangioblastoma (n=3), - and others- were obtained. The signal intensity of each tumor was visually assessed as one of four grades, and this and apparent diffusion coefficient(ADC) were analyzed in the solid and cystic portions of tumors, normal gray matter, white matter and CSF. RESULTS: Lymphomas, metastases, meningiomas, and high- and low-grade gliomas showed low ADC values in increasing order. Tumors showing high signal intensity on DW-MRI had low ADC values. Visual assessment whowed that solid portions of high-grade gliomas were significantly more hyperintense than those of low-grade gliomas. There was, however, no significant difference in ADCs between high- and low-grade gliomas. Lymphoma a and metastases showed significantly higher signal intensities on DW-MRI and lower ADCs than did high-grade gliomas. There were significant differences in signal intensities, as seen on DW-MRI, and in ADCs, between metastatic adenocarcinomas and non-adenocarcinomas. Schwannomas and cerebellar heman-gioblastomas showed low signal intensities and high ADC values. CONCLUSION: DW-MRI appears to provide an additional means of examining intracranial tumors, not available with conventional MRI, and may thus be helpful in the grading of gliomas and the differential diagnosis of some intracranial tumors.
