PURPOSE: A suprapubic approach to the suburethral polypropylene (SPARC) procedure was reported as a new technique for urethral support in the treatment of stress urinary incontinence in women. The safety and efficacy of the SPARC procedure were evaluated in women with stress urinary incontinence. MATERIALS AND METHODS: 50 women (mean age 48.6) with stress urinary incontinence underwent the SPARC procedure under general anesthesia between October 2002 and May 2004. The preoperative evaluations included: the patients history, a physical examination, urinalysis, an urodynamic test and incontinence staging for the Stamey grade. 2 and 5 women had previously experienced failed anti-incontinence surgery and pelvic surgery, respectively. The mean follow-up period was 8.01 months, with all patients assessed for the procedural outcome, subjective satisfaction and complications. RESULTS: The mean follow-up period, hospital stay and operation time were 8.01 months (3-15), 3.7 days (2-6) and 23 minutes (18-45), respectively. The success rate was 94%. There were no significant perioperative and postoperative complications. 3 patients (6%) had bladder perforation during the operation that necessitated an indwelling Foley catheter (mean period 7.3 days). 3 patients (6%) each had postoperative cystitis and immediate voiding difficulty that necessitated an indwelling Foley catheter (mean period 3.0 days) and bladder training, but without cutting or releasing of the tapes. 7 patients (14%) had postoperative de novo urge symptoms. CONCLUSIONS: The SPARC procedure is a simple, safe and effective treatment for female stress urinary incontinence in terms of the short operation time and hospital day, and low complication and relatively high success rates. However, a longer follow-up will be necessary to determine its long term effect and efficacy.

PURPOSE: Percutaneous aspiration with sclerotherapy is widely used as a treatment for simple symptomatic renal cysts because percutaneous aspiration with sclerotherapy is minimally invasive and cost-effective. Sclerotherapy is usually performed in combination with aspiration due to the high recurrence rate, 30-70%, for the simple aspiration. We conducted an analysis of percutaneous aspiration with repeated sclerotherapy, and we report the results of sclerotherapy after percutaneous aspiration of simple renal cysts and we also review the results of the other previous studies. MATERIALS AND METHODS: Between January 2001 and April 2004, the results of percutaneous aspiration with repeated sclerotherapy in 39 cases of simple renal cysts were evaluated. We evaluated the operation time, the hospital stay, the success rate, the complication rate and the follow-up period. All patients were available for follow-up over a period of 3 months by conducting ultrasound exams and computed tomography (CT) scans. RESULTS: Complete collapse, partial collapse and recurrence of the renal cysts occurred in 24/39 (61.5%), 13/39 (33.3%), and 2/39 (5.1%) cases, respectively. The mean operative time was 50.3 minutes and the mean hospital stay was 4.5 days. The cost of two sessions of sclerotherapy was about 240,000 won and that of three sessions of sclerotherapy was about 300,000 won. The size of the cyst was not related to the rate of collapse. Any complication related to percutaneous aspiration with repeated sclerotherapy were not noted. CONCLUSIONS: With regard for the success rate and cost-effectiveness, percutaneous aspiration with repeated sclerotherapy is considered a primary treatment for simple symptomatic renal cysts.

BACKGROUND: Blood supply circumstances in Korea have changed in recent decades because of blood supplier diversification and restructuring of hospital blood donation centers. The purpose of this study is to understand the current status of hospital blood donation centers and their satisfaction levels with the Korean Red Cross Blood Center (KRCBC) and compare with the previous results for sustainable development of the blood supply system. METHODS: During one month in November 2014, we conducted a questionnaire survey through e-mail in 64 hospital blood donation centers which are approved by government. The response rate was 97% (62/64 hospitals). Responses from 62 hospitals were analyzed. RESULTS: The number of hospital blood donation centers were reduced by half from 129 in 2004 to 64 in 2014. There was no blood donation center in hospitals less than 400 beds, except 2 hospitals; 23 hospital (37.1%) blood banks collected no blood components. More than 80% of hospitals were satisfied with the KRCBC service such as donor record lookup and nucleic acid amplification Test (NAT) results lookup. Hospitals with more than 1,000 beds replied that they would not take account of transferring the collection services to KRCBC because of the directed and autologous donation and unexpected emergency blood transfusion. CONCLUSION: The government should be the subject of national blood policy and establish a committee or agency for its comprehensive and consistent execution through close cooperation with the KRCBC and hospitals.

BACKGROUND: In hypertensive patients, the left ventricular hypertrophy(LVH) is very important as an independent risk factor along with developing complications. The present study was attempted to assess whether LVE assessed by echocardiography is related to diurnal variations of blood pressure in patiens with essential hypertension. METHOD: After 24hr ambulatory blood pressure monitoring, echocardiographic parameters were investigated in 30 healthy normotensive subjects and 17 patients with diurnal variation of blood pressure and 19 patients without diurnal variation respectively. RESULTS: Left ventricular mass index was higher in essential hypertensive patients than normotensive subjects. In patients without nocturnal fall in systolic blood pressure, left ventricular mass tended to be higher than in patients with a nocturnal fall without statistic significance. In the hypertensive patients with nocturnal fall, there was a correlationship between LVMI and changes in systolic blood pressure, but no correlation between left ventricular mass index and changes in diastolic blood pressure. In the hypertensive patients without nocturnal fall, changes of both systolic and diastolic pressure did not affect LVMI. CONCLUSION: It is suggested strongly that left ventricular hypertrophy may occur highly in the hypertensive patients without nocturnal(diurnal) variation in blood pressure and may be associated with changes in diastolic and systolic blood pressure. But in hypertensive patient with nocurnal fall, left ventricular hypertrophy may be associated with changes in systolic blood pressure.

Thyrotoxic periodic paralysis (TPP) is associated with hypokalemia and occurs sporadically and usually in young adult males. We report ten cases with TPP ; all were males, mean onset age was 32.4 years old. The duration of attack. Varied from 10 to 18 hours. The distribution of paralysis was confined to limb muscles; more severe in proximal limbs and lower extremities. Potassium levels during acute attack correlated with the severity of paralysis and ECG changes, but not with the severity of decrease in TSH level. In all cases, administration of potassium salts was successful in treatment of acute attack. A patient had further attack in spite of euthyroid state under the treatment of thyrotoxicosis for one year. Another patient was free from paralytic attacks by chronic administration of the potassium salt and acetazolamide without treatment of thyrotoxicosis.

Background:
Due to the importance of the cold chain related to vaccine transportation, it is necessary to establish a blood cold chain operation strategy by checking the status of blood transportation from blood donation to transfusion.
Methods:
The blood transportation system and blood storage facilities were checked by inspecting the Korean Red Cross (KRC) Blood Centers and its affiliated supplier and Hanmaeum Blood Center. The status of the cold chain was evaluated through an interview with the quality control manager or blood supply team leader. For the hospital, the status was investigated from the perspective of the 30-min rule. A questionnaire survey was conducted for medical technicians and nurses working at the hospital.
Results:
Data on temperature during transport of blood components were computerized, and all standards were met. A nationwide network that could supply blood from the blood supply center to the hospitals within 2 hours was established. The frequency of temperature monitoring in the blood transport box and constant temperature check in the transport box during long-distance transport were evaluated.
Conclusion
This study confirmed that blood storage and transportation in Korea complied with the cold chain standards of high-income countries or higher. The evaluation of the cold chain is a constantly evolving process requiring continuous attention. When standards for storage and transportation of blood products are established, strict regulations and examinations will be required.

Heterotopic pregnancy, simultaneous intrauterine and extrauterine gestations, is a relatively rare condition with an estimated incidence of 1 in 30,000 pregnancies. The incidence of heterotopic pregnancies have increased in recent years because of rising incidence of pelvic inflammatory disease, pelvic surgery, expanding use of assisted reproductive technology. Common sites of extrauterine gestation are salpinx, cornus and cervix of uterus, ovary, and abdomen in order of incidence. Early detection of heterotopic pregnancy is very difficult and is often more difficult in the case of abdominal pregnancy. However, to avoid high maternal morbidity, mortality, and loss of pregnancy, one should always take this into consideration and should conduct careful and thorough gynecologic evaluations. We have experienced a case of abdominal pregnancy following termination of intrauterine pregnancy in a 23-year-old unmarried woman and report it with brief review of literatures.

BACKGROUND: Korean Blood Safety Commission has implemented external proficiency testing (PT) for blood grouping test (BGT) to help improve the quality of blood centers since 2011. We analyzed the results of 2014 PT for BGT to help in planning the future PT for BGT and to improve the quality of blood centers. METHODS: Whole blood survey samples including three panels for ABO grouping and three panels for D typing were sent to 69 institutes. Evaluation criteria for BGT were as follows: 'Good' for answers matched with intended results, 'Acceptable' for correct answers other than that of 'Good', 'Unacceptable' for answers other than those of 'Good+acceptable' as correct answers; and 'Not graded' for answers in case of different answers in the two standard laboratories. RESULTS: All of the answer rates of 'Good' for D typing were 100%. However, the answer rates of 'Good' for cell typing, serum typing and interpretation for 14-ABO-2 samples with discrepant result between cell typing and serum typing were 39.1%, 29%, and 47.8%, respectively. Those of 'Unacceptable' for cell typing and interpretation for 14-ABO-2 samples were 2.8% and 1.4%. CONCLUSION: Because the answer rates of ABO grouping for samples with discrepant result between cell typing and serum typing were not high, education for this case is needed. Diversity of materials for PT would be necessary for more accurate evaluation of the performance of BGT in blood centers.
