Objectives: Graves’ orbitopathy (GO) is an autoimmune condition linked with Graves’ disease (GD). This study focuses on the relationship between statin dose trajectories and the risk of developing GO among GD patients using the data from the National Health Insurance Service (NHIS). Methods: Utilizing the KmL (k-means for longitudinal data) clustering algorithm, we categorized patients with GD and hyperlipidemia into three distinct groups based on their two-year pre-diagnosis statin dosage. A Cox proportional hazards model with inverse probability weighting (IPW) was applied to evaluate the risk of GO across the identified clusters. Results: The findings suggest that patients within the ‘Moderate’ statin dosage cluster are at a statistically lower risk of developing GO compared to those who did not use statins (p =0.048). Conclusions: Moderate statin use significantly reduces the risk of GO in GD patients. These findings support the potential role of statins in GO prevention.

Fasciotomy wounds are a major contributor to prolonged hospital stay and can lead to amputation. Although it is generally recommended to close the fasciotomy wound as early as possible, it is usually challenging. Primary closure is more favorable because it commences more functional and esthetic results with less morbidity. But primary closure is difficult to achieve due to skin edema, retraction and necrosis. Topical negative pressure care (TNP) has been used in other areas of wound care, such as mediastinitis and burn wounds. TNP has recently gained popularity and has shown promising outcomes. Topical negative pressure systems are commercially available but very expensive. We designed a modified negative pressure system with wall-suction and applied it to a com- plicated fasciotomy wound. We herein report our experience with a review of related literatures.

This study was performed to identity of the workers' recognition about the environmental measurement of small and medium scale industry from September, 2001 to October, 2001 in lnchon area. The 277 workers in 38 companies were surveyed by checklist contented the recognition, experience, and confidence for work environment measurement and improvement. The definition and object for work environmental measurement were recognized 59.19% and 91.29 of workers, respectively. The 98.11% of workers insisted that the explanation meeting for the report of work environmental measurement should be performed. The 76.15% of workers thought the most hazardous agent in workplace are noise and dust. It is suggested that the result of work environmental measurement be provided to the workers for supplying information of the workplace and the regulation be revised to secure the right to know of workers.
Symptomatic Renal Artery Aneurysm Dealt with Aneurysmectomy and Patch Closure

Renal artery aneurysm (RAA) is a rare disease, and the precise incidence has not been very well known. It appears that with the increasing use of diagnostic ultrasound, computed tomography and arteriography, RAA are being identified more frequently than in the past. Rupture of RAA is associated with 10% mortality and the chance of nephrectomy is very high. Although, most of renal artery aneurysms are treated by endovascular technique, surgery is often necessary for aneurysms associated with bifurcation area or large braches. Here, we report a case of saccular renal artery aneurysm which was managed by open surgery.

A novel method for the reconstruction of 3D shape and texture from elemental images has been proposed. Using this method, we can estimate a full 3D polygonal model of objects with seamless triangulation. But in the triangulation process, all the objects are stitched. This generates phantom surfaces that bridge depth discontinuities between different objects. To solve this problem we need to connect points only within a single object. We adopt a segmentation process to this end. The entire process of the proposed method is as follows. First, the central pixel of each elemental image is computed to extract spatial position of objects by correspondence analysis. Second, the object points of central pixels from neighboring elemental images are projected onto a specific elemental image. Then, the center sub-image is segmented and each object is labeled. We used the normalized cut algorithm for segmentation of the center sub-image. To enhance the speed of segmentation we applied the watershed algorithm before the normalized cut. Using the segmentation results, the subdivision process is applied to pixels only within the same objects. The refined grid is filtered with median and Gaussian filters to improve reconstruction quality. Finally, each vertex is connected and an object-based triangular mesh is formed. We conducted experiments using real objects and verified our proposed method.

Purpose: Although cyclosporine (CsA) improves short-term renal graft outcomes, many paradigms reduce or withdraw this drug because of its nephrotoxicity. However, inadequate immunosuppression with azathioprine led to little success. We conducted a prospective study to define the prolonged effect of CsA reduction in stable renal transplant recipients with mycophenolate mofetil (MMF). Methods: Thirty-nine primary renal transplant recipients were divided into two cohorts, the AZA (N=13) and the MMF cohort (N=26). Both cohorts were allowed to reduce the CsA dose up to 50% of baseline within 3 to 4 months of conversion to AZA or MMF. Graft function, clinical parameters, and adverse events were monitored for up to 3 years. Results: Ccr gradually deteriorated in the AZA cohort, but was stable in the MMF cohort. There was no episode of acute rejection or graft loss observed in either cohort. Conclusion: The CsA dose can be reduced in combination with MMF treatment in stable renal transplant recipients after 2 years of transplantation, resulting in beneficial effects on Ccr, lipid profiles, and blood pressure.
