The purpose of this study was to evaluate the microbiological quality, and to assure the safety of the food production process in the university foodservice facilities in accordance with the Hazard Analysis Critical Control Point(HACCP) concepts. The kitchen layout and time-temperature relationship, miciobiological quality(total plate count, coliform) were assessed to identify the critical point during each of the production phases. The results were as follows: 1) The kitchen layout had to be improved because contamination area was not separated from non-contamination area, and work table was in contact with washing sink. 2) Some employee did not follow personal hygiene standards(hand washing), and did not wear proper working uniforms(hair restraints). 3) The production time of tuna salad was 120 min, and environment temperature was 20.1~26.0℃. Improper receiving temperature, inproper holding practices(without cover at room temperature) were observed. 4) In the purchasing phase of the raw materials, the microbiological quality of green pepper was not at acceptable level based on the TPC(2.3×10^6CFU/g)and coliform(>14,000 MPN/g). During washing phase TPC was decreased about 3 log cycle. After cutting and holding phase the level of TPC and coliform were increased rapidly. At serving phase the microbiological quality of tuna salad were not at acceptable level(TPC 3.3×10^6 CFU/g, coliform 11,000 MPN/g) according to the standard set(TPC <10^5 CFU/g, coliform <100 MPN/g) by Sorberg et al. 5) For tuna salad, critical control points were purchasing and receiving of fresh vegetables, washing, cutting, holding, mixing and serving phase.

Osteochondroma is one of the most common benign bone tumors. It is easy for dermatologists to misdiagnose osteochondroma on the fingers or toes as other cutaneous tumors including pilomatricoma, epidermal cyst, and glomus tumor. We report a case of a 42-year-old woman presenting with a palpable mass on the left thumb. Skin biopsy was performed in the other hospital a year ago and she heard the result as a viral wart. In our hospital, the tumor was checked by X-ray, which showed a calcified nodule on the distal phalanx. Bizarre parosteal osteochondromatosis proliferation was suspected on MRI but bony connection between a bony spur and the distal phalanx was obscure. We additionally performed a computed tomography, which revealed a 5mm-sized bony spur connected with cortical bone. Specimen after orthopedic surgery showed fibrous tissue and cartilage cap composed of hyaline cartilage. Based on these findings, we concluded her tumor is an osteochondroma masquerading as viral wart.

Vascular thrombosis in the venous or arterial system is quite common in systemic lupus erythematosus(SLE), especially in patients who have active disease with vasculitis and antiphospholipid antibodies(aPL). These thrombotic events usually developed on deep veins of the lower extremities and very rarely occur on the upper extremities. The upper extremity deep vein thrombosis(UEDVT) is a relatively rare disease, constituting about 2% of all cases of deep venous thrombosis, and usually occurs axially and subclavian vein. Here, we report an unusual case of brachial and basilica vein thrombosis in a 34-yr-old woman with SLE after taking oral contraceptives for 3months before the onset of upper-extremity deep vein thrombosis(UEDVT). Venous Doppler ultrasonography and CT images showed thrombosis and thrombophlebeitis of the brachial and basilica vein of the left arm. Thrombophilia work-up including IgM and IgG anticardiolipin antibodies, lupus anticoagulant were negative. Protein C, Protein S, and antithrombin 3 levels were within normal range. The patient was started anticoagulation therapy and oral contraceptives were discontinued. After that, she was asymptomatic and she had been treated with aspirin 100mg/day.

Background/Aims: In patients with ESRD who are undergoing hemodialysis, the various clinical and laboratory values are known to be changed by season, although they vary by study. This study aimed to investigate the relationship between the seasonal variations and each biochemical parameters in hemodialysis. Methods: From December 2007 to November 2010,22 patients with ESRD were included in this study. Clinical and laboratory test was performed monthly. The results were analyzed every three months. Then correlation between seasonal variations and relevant factors was analyzed. Results: Seasonal variations were observed in systolic and diastolic blood pressure, total protein, albumin, glucose, creatinine, total CO2 and potassium. Interdialytic variations in hemoglobin, total protein, alb니min,glucose, and potassium and increased body weight were found to have significant influence on the sodium. In both diabetic and non-diabetic groups, significant variations were observed only in sodium and glucose. In heart fail니re and normal groups, no significant variation was observed. Conclusions: Clinical and laboratory values in patients undergoing hemodialysis has seasonal variations. Awareness of these variations will allow seasonal adjustment of nutrition education for hemodialysis patients, prediction of changes in electrolytes and relevant factors, and improvement of the quality of life and clinical prognosis.

This study aimed to investigate the effects of various mixtures of the chicken skin and wheat fiber on the properties of chicken nuggets. Two skin and fiber mixtures (SFM) were prepared using the following formulations; SFM-1: chicken skin (50%), wheat fiber (20%), and ice (30%); and SFM-2: chicken skin (30%), wheat fiber (20%), and ice (50%). Chicken nugget samples were prepared by adding the following amounts of either SFM-1 or SFM-2: 0%, 2.5%, 5%, 7.5%, and 10%. The water content for samples formulated with SFM-1 or SFM-2 was higher than in the control (p<0.05), and increased with increasing the concentrations of SFM-1 and SFM-2. The addition of SFM-1 and SFM-2 had no significant effect on the pH of the samples. The lightness value of uncooked chicken nuggets was higher than that of cooked chicken nuggets for all the samples tested. Chicken nuggets formulated with SFM-1 and SFM-2 displayed higher cooking yields than the control sample. The hardness of the control sample was also lower than the samples containing SFM-1 and SFM-2. The sensory evaluation showed no significant differences between the control and the samples containing SFM. Therefore, the incorporation of a chicken skin and wheat fiber mixture improved the quality of chicken nuggets.

Objective : The purpose of this study was to evaluate the efficacy of implant removal of percutaneous short segment fixation after vertebral fracture consolidation in terms of motion preservation. Methods : Between May 2007 and January 2011, 44 patients underwent percutaneous short segment screw fixation due to a thoracolumbar burst fracture. Sixteen of these patients, who underwent implant removal 12 months after screw fixation, were enrolled in this study. Motor power was intact in all patients, despite significant vertebral height loss and canal compromise. The patients were divided into two groups by degree of osteoporosis : Group A (n=8), the non-osteoporotic group, and Group B (n=8), the osteoporotic group. Imaging and clinical findings including vertebral height loss, kyphotic angle, range of motion (ROM), and complications were analyzed. Results : Significant pain relief was achieved in both groups at final follow-up versus preoperative values. In terms of vertebral height loss, both groups showed significant improvement at 12 months after screw fixation and restored vertebral height was maintained to final follow-up in spite of some correction loss. ROM (measured using Cobb's method) in flexion and extension in Group A was $10.5^{\circ}$ ($19.5/9.0^{\circ}$) at last follow-up, and in Group B was $10.2^{\circ}$ ($18.8/8.6^{\circ}$) at last follow-up. Both groups showed marked improvement in ROM as compared with the screw fixation state, which was considered motionless. Conclusion : Removal of percutaneous implants after vertebral fracture consolidation can be an effective treatment to preserve motion regardless of osteoporosis for thoracolumbar burst fractures.

Background: Skin types are various, therefore it is hard to find out them at a glance. To understand them effectively, analysis based on questionnaire could be helpful. Objectives: The purpose of this study is to identify the accuracy and effectiveness of Baumann skin type questionnaire (BSTQ) as compared with an interview with dermatologic specialist. In addition, we aim to find out the difference of skin type proportions according to age and invent a modified BSTQ. Methods: Two-hundred-two women who visited the dermatologic clinic of Kangbuk Samsung hospital, aged 19-64, were enrolled as subjects. They performed both BSTQ and an interview with dermatologic specialist. Modified BSTQ was invented by removing similar and racial questions and adjusting grading scores. Results: The agreement between skin type proportions analyzed by BSTQ and an interview is not reasonable (リ =0.428, 95% CI: 0.363-0.493). There is a weak correlation between the proportion of dryness and age (r=0.208, p<0.01). However, other skin type proportions (sensitivity, pigmentation, and wrinkle) are not significantly correlated with age. Modified BSTQ showed substantial agreement with BSTQ in skin type proportions (リ=0.691, 95% CI: 0.641-0.740). Conclusion: We identified the skin types of Korean women of various ages by BSTQ and an interview. Furthermore, the modified BSTQ might be helpful to recognize skin types concisely.
