Blood utilization review has recently been used to minimize inappropriate transfusion, reduce post transfusion infections and improve the quality of transfusion practices. Ajou University Hospital is a 906 bed tertiary care teaching institution. Since March, 1995, the concurrent review of blood transfusion requests using institutional blood transfusion criteria has been initiated. To evaluate the effectiveness of the transfusion review, the units of blood components transfused per patient(total number of units of blood components transfused/total number of patients discharged) and inappropriate transfusion ratio of blood components(total number of units of blood components inappropriately transfused/total number of units of blood components transfused) were compared during the concurrent review for 9 months and pre-concurrent review for 9 months, respectively. The possible savings of blood components realized by the review were also extrapolated. The results were as follows : 1. The unit transfused per patient for pre-review and during review were 0.675 (9,080/ 13,422) and 0.654(12,123/18,546) for packed RBC(PRBC); 0.417 (5,602/ 13,422) and 0.296 (5,444/18,546) for fresh frozen plasma(FFP); 0.372(5,007/13,422) and 0.424(7,868/18,546) for platelet con-centrates(PC), respectively. 2. The inappropriate transfusion ratio of blood components for pre-review and during review were 0.039 and 0.009 for PRBC; 0.321 and 0.064 for FFP; 0.143 and 0.008 for PC, respectively. These differences were statistically significant(p=0.000). 3. The PRBC and FFP anticipated to have been saved by this review was 519 units and 2,992 units annually, respectively. 4. However, 2,621 units of PC were used additionaly during this review due to increased number of oncology patients and better hemostatic therapy practiced during the same period. In conclusion, the concurrent review of transfusion requests was very effective tool to educate residents in clinical departments the transfusion medicine and improve utilization of blood and its components.

Background and Objectives: This study aimed to examine factors of poor outcome by analyzing
the outcomes of bilateral subthalamic deep brain stimulation in Parkinson’s disease after 3 years.
Methods: We assumed that patients who could not manage independent life in their best stimulationon/medication-on
condition after a defi ned period might not have been a good surgical candidate.
A poor outcome is defi ned as a failure to maintain functional independence at three years during a
stimulation-on/medication-on state. Results: A total of 84 patients underwent bilateral subthalamic deep
brain stimulation and all were followed up for 3 years. We excluded one patient who had intracranial
hemorrhage. Twenty-one patients of the 83 patients could not keep up independent life even during
their best condition for the following reasons: freezing in 15 patients, dementia in 5, depression in 3,
musculoskeletal problems in 7, and cancer in one patient.
Conclusions: Many patients could not keep up independent life during their best condition as early as
three years after deep brain stimulation. Musculoskeletal problems were one major cause of disabilities,
as were freezing and dementia. We emphasize that musculoskeletal problems need more attention in
the preoperative screening of deep brain stimulation candidates and during the follow up.

Endogenous nitric oxide (NO) has been known to regulate the salivary secretion and glandular blood flow. However, the distribution of nitric oxide synthase (NOS) responsible for NO synthesis has not been well studied in salivary glands. The present study was aimed to investigate the distribution of nitric oxide synthase isoforms (endothelial, neuronal, and inducible NOS). Immunohistochemistry, using monoclonal mouse anti-endothelial NOS, anti-neuronal NOS, and anti-inducible NOS, was performed in 3 major salivary glands (parotid, submandibular and sublingual gland) of the rat. Endothelial NOS (eNOS)-positive immunoreactivity was observed in arterial endothelium, striated duct, granular convoluted duct of the submandibular gland, intercalated duct, and mucous acinar cells of the sublingual gland. The eNOS-positive immunoreactivity was most prominent in the arterial endothelial layer and that of the striated and granular convoluted duct was well concentrated in columnar epithelial layer. In the intercalated duct and mucous acinus, eNOS-positive immunoreactivity was weakly detected. Neural NOS (nNOS)-positive immunoreactivity was observed in submandibular ganglion, autonomic postganglionic fiber, striated duct, granular convoluted duct, and intercalated duct. nNOS-positive immunoreactivity of the submandibular ganglion and autonomic postganglionic fiber was most prominent and that of the ductal system was well concentrated in the epithelial layer. eNOS-positive immunoreactivity was not detected either in excretory ducts or in serous acinar cells. Inducible NOS-positive immunoreactivity was not detected. There results reveal the presence of eNOS and nNOS in the salivary gland, which may be related with regulation of the glandular secretion and blood flow through synthesis and secretion of NO.

PURPOSE: To evaluate the safety and efficacy of repeat trabeculectomy with mitomycin C (MMC) in the management of previous failed trabeculectomy patients. METHODS: We retrospectively reviewed the medical records of 44 eyes of 41 glaucoma patients who had been followed up for at least 6 months after repeat trabeculectomy with MMC and analyzed the success rates according to clinical factors, cumulative success rates, risk factors for surgical failure and complications. Surgical success was defined as an intraocular pressure (IOP) of 21 mmHg or less regardless of glaucoma medications and loss of vision. RESULTS: Postoperative success was obtained in 34 (77.3%) out of 44 eyes after a mean follow-up period of 38.7 months. From Kaplan-Meier survival analysis, cumulative success rates after 6, 12, 24, and 36 months were 97.7%, 89.6%, 83.5%, and 80.1%, respectively. Success rates were significantly lower in eyes with preoperative IOP of 30 mmHg or more. Postoperative complications included transient hypotony in 7 eyes, choroidal detachment in 4, hyphema in 4, and cataract progression in 4. CONCLUSIONS: The success rates of repeat trabeculectomy may be lower than of primary trabeculectomy. However, considering the relatively high success rates and low complications of repeat trabeculectomy with MMC compared to the reported results of glaucoma drainage device implantation, repeat trabeculectomy with MMC is an effective and relatively safe surgical option as the secondary surgical procedure for previously failed trabeculectomy patients.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.
