3.Microbial Risk Analysis of Cooked Foods Donated to Foodbank(I).
Korean Journal of Community Nutrition 2007;12(5):617-629
To ensure the microbiological safety of food items prepared after cooking process, this study was aimed to identify the hazards related with cooked foods donated to foodbanks through quantitative microbial analysis. Five foodbanks located in Incheon and Gyeonggi area among government-dominant foodbanks were surveyed from February to June, 2007. Manager, recipient, donator, type and quantity of donated food, and facility and equipment were examined for the general characteristics of foodbank. The time and temperature of food and environment were measured at steps from after-production to before-distribution, and the microbial analysis was performed mainly with indicator organism and major pathogens. The amount of cooked foods donated to each foodbank was about 20 to 30 servings and consisted of 80% of total donated foods. Only three foodbanks had separate offices for foodbank operation and four institutions had at least one temperature-controlled vehicle. The flow of donated foods was gone through the steps; production, meal service and holding at donator, collection by foodbank, transport (or holding after transport) and distribution to recipients. It took about 3.8 to 6.5 hours at room temperature from after-production to beforedistribution. Only aerobic plate counts (APC) and coliforms were found in microbial analysis. The APC after production were relatively high in 8.2 x 10(5), 7.4 x 10(5), 6.9 x 10(5) and 4.2 x 10(5) CFU/g while 2.8 x 10(6), 9.4 x 10(5), 1.0 x 10(6) and 5.4 x 10(5) CFU/g before distribution in mixed Pimpinella brachycarpa, mixed chard, mixed amaranth and mixed spinach, respectively. The levels of coliforms in mixed chard and mixed spinach were complied with the standards of the Ministry of Education and Human Resources Management. The level of APC in boiled pork was increased from < 1.0 x 10 CFU/g to 4.0 x 10(2) CFU/g. One of delivery vessels was shown 6.2 x 10(3)CFU/100 cm2 in APC, which was over the standards for environment. One of serving tables also showed the high level of 1.2 x 10(3) CFU/100 cm2 in APC and 6.6 x 10(2) CFU/100 cm2 in coliforms. These results suggest the sanitary management of holding at donator and the time-temperature control are key factors to ensure the safety of cooked foods donated to foodbank.

4.The Value of Urine Cytology and Flow Cytometry in Superficial Bladder Tumors.
Korean Journal of Urology 1994;35(3):224-229
Although urine cytology has been used as a useful diagnostic and followup procedure for bladder tumors, it has difficulties in diagnosing low grade and superficial bladder tumors. Recently, flow cytometric DNA analysis is developing an increasing role in the evaluation of patients with possible urothelial malignancy. We evaluated the value of urine cytology and flow cytometry in the diagnosis and the followup of 91 patients with superficial bladder carcinoma between January 1989 and December l992. Positive cytology was detected in 37.4 percent of 91 patients. Among the 74 patients who were examined by urine cytology and flow cytometry, the detection rate was 39.2 percent by cytology, 47.3 percent by flow cytometry and 60.8 percent when both modalities were used. In the 33 recurrences, the detection rate was 63.6 percent by cytology, 57.6 percent by flow cytometry and 75.8 percent by both modalities. The results of this study indicated that urine cytology and flow cytometry have relatively low sensitivity in the diagnosis of superficial bladder tumors, but have higher sensitivity in recurrent tumors. A combination of urine cytology and flow cytometry increased diagnostic accuracy. In conclusion, the combination of urine cytology and flow cytometry is a useful adjunct procedure for the diagnosis and followup of patients with superficial bladder tumors.

5.Microbiological Hazard Analysis of Cooked Foods Donated to Foodbank (II).
Journal of the Korean Dietetic Association 2007;13(4):389-406
This study was conducted to estimate the safety level of non-cooking and cooking processed foods to propose the sanitary management of foods donated to foodbanks. The time and temperature were measured and the microbial levels of aerobic plate counts (APC), coliforms, E. coli, Salmonella spp., S. aureus, B. cereus, and E. coli O157:H7 were analyzed on ten food items donated to seven foodbanks. The amount of cooked foods donated to each foodbank was about 10 to 40 servings. All foodbanks hired a supervisor and had at least one refrigerator/freezer and one temperature-controlled vehicle, but only four foodbanks had the separate offices to manage the foodbank operation. The flow of donated foods was gone through the steps; production, meal service and holding at donator, collection by foodbank, transport (or holding after transport) and distribution to recipients. After production, the levels of APC of both non-cooking and cooking processed foods were complied with the standards by Ministry of Education & Human Resources Development, and were not increased till distribution. Only the level of coliforms in dried squid & cucumber salad (1.5x10(3) CFU/g) was not met the standards. E. coli and other pathogens were not detected in all tested samples. The microbial levels of delivery vessels and work tables were satisfactory, but the APC levels of two of four tested serving tables (6.9x10(3) and 5.3x10(3) CFU/100cm2) and the coliforms level of one (1.1x10(3) CFU/100cm2) were over the standards. The air-borne microflora level in serving room was estimated as satisfactory. It took about 3.0 to 6.5 hours from after-production to distribution and the temperatures of donated foods were exposed mostly to temperature danger zone, which had a high potential of microbial growth. These results imply that a checklist to monitor time and temperature in each step should be provided and the employees involving foodbank operation should be properly educated to ensure the safety of donated foods.

We report a case of renoduodenal fistula resulting from papillary renal cell carcinoma. A 72-year-old woman presented with nausea, diarrhea and abdominal discomfort. Abdominal CT, UGI and sinography revealed fistula between the right renal mass and the duodenum. Radical nephrectomy and duodenal wedge resection was performed and a friable mass with a fistula between the lower pole mass of the right kidney and second portion of the duodenum was found. Histologic evaluation for renal mass showed papillary renal cell carcinoma. We describe this case and review the previously reports of renoduodenal fistulae.

The reconstruction of foot remains difficult problem with many surgical modalities because foot has unique structure, insufficient local soft tissue and poor vascularity. The medial plantar island flap is capable of providing sensate and structurally similar tissue with single operative procedure. We reconstructed 5 cases of soft tissue defects on the foot by using medial plantar island flap(3 cases proximally- based, 2 cases distally-based) in diabetics. Successful soft tissue coverage was achieved on medial malleolus, dorsal midfoot, tendo calcaneus, and forefoot. The size of flap ranged from 3.5 x 3.0 cm to 6.0 x 4.0 cm. Follow-up ranged from 8 months to 26 months. All flaps survived without serious complication. All patients had protective sensation in daily activities and were able to ambulate in normal footwear. This paper demonstrates that medial plantar island flap with proximally and distally-based pedicle should be considered as a useful technique for reconstruction of soft tissue defect from ankle to forefoot.

8.A Case of Hypertensive Crisis without a Surge in Adrenal Hormones after Radiofrequency Ablation as a Treatment for Primary Hepatocellular Carcinoma.
The Korean Journal of Gastroenterology 2017;70(4):198-201
Radiofrequency ablation (RFA) is a minimally invasive procedure that has been considered as a relatively safe treatment for patients with small hepatocellular carcinoma (HCC). However, RFA has been shown to be associated with complications including mechanical and thermal damage. A 74-year-old man with hepatitis C virus-associated HCC was admitted to our hospital. Abdominal computed tomography revealed two lobulated-HCC in segments 4 and 5. He had no medical history of hypertension and cardiac disease. During RFA, blood pressure was elevated to 200/140 mmHg. There was no evidence of pulmonary embolism, aortic dissection, or ischemic heart disease. Laboratory findings for catecholamine surge were all within normal limits. After continuous intravenous nitroglycerin and oral beta-blocker treatment, patient's blood pressure gradually decreased and back within the normal range. Hypertensive crisis after RFA treatment for HCC is rare. Most reported cases of hypertensive crisis during RFA were related to adrenal gland injury with a release of catecholamine. In our case, the site of HCC was not close to the adrenal gland, and there was no evidence of catecholamine surge. Herein, we report a very rare case of hypertensive crisis without a surge in adrenal hormones after RFA treatment for HCC.

BACKGROUND: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. METHODS: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. RESULTS: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 +/- 7.9 mm versus 7.3 +/- 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. CONCLUSIONS: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.
