This study was conducted to evaluate the effectiveness of a combination of gemcitabine and nedaplatin therapy among patients with metastatic urothelial carcinoma previously treated with two lines of chemotherapy. Between February 2009 and August 2013, 30 patients were treated with gemcitabine and paclitaxel as a second-line chemotherapy. All had received a first-line chemotherapy consisting of methotrexate, vinblastine, doxorubicin and cisplatin. Ten patients who had measurable histologically proven advanced or metastatic urothelial carcinoma of the urinary bladder and upper urinary tract received gemcitabine $1,000mg/m^2$ on days 1, 8 and 15 and nedaplatin $70mg/m^2$ on day 2 as a third-line chemotherapy. Tumors were assessed by imaging every two cycles. The median number of treatment cycles was 3.5. One patient had partial response and three had stable disease. The disease-control rate was 40%, the median overall survival was 8.8 months and the median progression-free survival was 5.0 months. The median overall survival times for the first-line and second-line therapies were 29.1 and 13.9 months, respectively. Among disease-controlled patients (n=4), median overall survival was 14.2 months. Myelosuppression was the most common toxicity. There were no therapy-related deaths. Gemcitabine and nedaplatin chemotherapy is a favorable third-line chemotherapeutic option for patients with metastatic urothelial carcinoma. Given the safety and benefit profile seen in this study, further prospective trials are warranted given the implications of our results with regard to strategic chemotherapy for patients with advanced or metastatic urothelial carcinoma.

Purpose: This study was a predicative survey to provide home care clients with indwelling urinary catheters for furnishing basic educational material to their families by analyzing the family members' knowledge, educational needs and educational experience about indwelling catheter management. Method : The subjects consisted of 108 family members who cared for home care clients with indwelling catheters. Data were collected by home care nurses in nine hospitals in Pusan, who directly interviewed with them through questionnaires from Sep. 6th to 30th in 2004. The questionnaires for data collection were developed through pre-survey and reference review. The collected data was analyzed by using frequency, percentile, mean, variation, t-test, ANOVA on SPSS 10.1 package. Results : There were characters of home care clients with indwelling catheters: women(67.6%) were more than men; the average age of them was $69.60{\pm}14.99$ years old; neurogenic and cerebrovascular diseases(80.0%) were the most common disease group; 81.5% of them were totally dependent on others in terms of level of activity. Home care clients' families had these characters: women(76.9%) were more than men; the average age was $54.5{\pm}13.70$ years old; 46.3% of them were parents or sons or daughters in terms of relation with patient; tl1e average care period was $39.8{pm}34.20$ months. Level of knowledge about indwelling catheter management of the family members were 69.8% and its mean were $20.24{\pm}4.53$. Educational needs were 90.9% and its mean were $14.55{\pm}3.56$. Educational experience were 53.3% and its mean were $8.53{\pm}4.30$. 'Complications in using an indwelling catheter', 'Symptoms to call for a home care nurse' and 'Method to attach an indwelling catheter' were high ranked in both educational needs and educational experience. 'Anatomy of urinary tract', 'Functions of urinary tract' and 'Catheter placement' were low ranked in both educational needs and educational experience Level of knowledge about indwelling catheter management of the families showed a significant difference according to their age(F=5.35, p=0.01). Educational needs showed a significant difference according to care period(F=3.06, p=0.04). Conclusion: the family members' level of knowledge and educational experience about indwelling catheter management and their educational were not sufficient while their educational needs were high. In other words although the family members were acknowledged education needs, but the care for the patients with indwelling catheter weren't performed well because of their lack of related knowledge. Therefore systematic educational programs about indwelling catheter management for home care clients and their families should be made on the base of this study.

목적: 요로감염은 소아에서 흔한 세균 감염이며, Escherichia coli가 주요 원인균이다. 본 연구는 우리나라에서 소아 요로감염을 일으키는 E. coli의 계통 분류와 독성인자를 분석하고자 하였다. 방법: 2010년 10월부터 2013년 4월까지 요로감염으로 입원한 33명의 소아 환자로부터 검출된 E. coli균주를 대상으로 하였다. 중합효소연쇄반응을 통해 E. coli의 계통 분류 및 5가지 독성인자(fimH, sfa, papA, hylA, and cnf1)를 조사하였다. E. coli의 분자유전학적 특징을 환자의 임상적 진단과 동반된 방광요관 역류에 따라 분석하였다. 결과: 대부분의 요로병원성 E. coli 는 계통 분류에서 B2군(84.8%)에 속했으며, 나머지는 모두 D군(15.2%)에 해당되었다. 독성인자는 fimH (100%), sfa (100%), hylA (63.6%), cnfI (63.6%), 그리고 papA (36.4%)의 분포를 보였다. 임상 진단에 따른 계통 분류에서 급성 신우신염의 경우 B2군이 92.3%, D군이 7.7%를 나타냈으며, 방광염에서는 B2군에서 57.1%, D2군은 42.9%였다. 독성인자는 양 군에서 비슷하게 분포하였다. 급성 신우신염에서 방광요관 역류의 유무에 따른 계통 분류의 분포에는 차이가 없었으나, 독성인자의 경우 papA 유전자가 방광요관 역류가 동반되지 않은 군에서보다 방광요관 역류 군에서 적게 나타났다(43.8% vs. 20.0%, P=0.399). 결론: 본 연구는 국내 소아 요로감염의 원인 E. coli 균주의 분자유전학적 역학 자료를 제시하였으며, 이 결과는 향후 소아 요로감염의 발생 기전을 이해하는 데 기초가 될 것으로 생각된다.

The authors applied anterior sagittal transrectal apporach (ASTRA) for the repair of urethrovaginal fistula which developed after total repair of persistent cloaca. The patient had been diagnosed to have persistent cloaca, double uterus and double vagina, and received PSARP, excision of right-side uterus and vagina, and left vaginal switch operation at 22 months old. After operation, the patient admitted several times due to frequent urinary tract infection and ectopic stone formation in bladder and neovagina. Urethro-neovaginal fistula was confirmed by cystoscopy and corrected with ASTRA. Postoperative voiding cystourethrogram showed no fistula tract. ASTRA showed improved surgical field, minimized ureterocystic damage, and preserved perirectal nerve due to limited incision of rectum.

Inferior mesenteric plexus block(IMPB) is a nerve block for lower abdominal pain originating from GI tract of distal transverse colon to sigmoid colon and other polvic organ where the inferior mesenteric plexus contains visceral afferent fibers of that organ. We performed IMPB on two patients with lower abdominal pain. Case I: 61 year old female diagnosed with cancer of stomach and uterine cervix and carcinomatosis, experienced complete relief from pain for a period of 7 months after IMPB. Case II: male, 28 years old, who had contracted cancer of the descending colon with obstructive jaundice and pancreatitis had complained of pain in the whole of the abdominal area. IMPB was performed for lower abdominal pain. Seven days after, a celiac plexus block was also performed for upper abdominal pain. The patient complained of recurring pain in the left & upper lower abdomen 30 days after the IMPB. The intensity of the pain was visual analogue scale 4 and it was managed by continuous epidural block. Conclusion: It is our recommendation that IMPB is a reliable method for treatment of lower abdominal pain originating from malignant condition of GI tract from distal transverse colon to sigmoid colon and urinary bladder.

The resistant strains due to the extended-spectrum $\beta$-lactamase (ESBL) were susceptible to cefatrizine combined with clavulanic acid. The purpose of this study was to evaluate the in vitro and in vivo antibacterial activities of cefatrizine/clavulanic acid (CTRZ/CV) combination at a ratio of 2 : 1 in comparison with cefaclor (CCLO), cefuroxime (CRXM), cefuroxime axetil (CRXMA) and amoxicillin/clavulanic acid (AMXCCV). CTRZ/CV showed good activity against laboratory strains of gram-positive and gram-negative bacteria and exhibited excellent antibacterial activity against $\beta$-lactamase-producing strains. The bactericidal activity of CTRZ/CV was superior to that of CCLO and CRXM, and almost equal to that of AMXCCV against the $\beta$-lactamase-producing strains. The in vitro results were substantiated. by in vivo mouse experimental infection studies with $\beta$-lactamase-producing and non-producing strains. In mixed experimental infection due to $\beta$-lactamase-producing and non-producing strains, the therapeutic efficacy of CTRZ/CV was superior to that of CTRZ, CCLO, CRXMA and AMXCCV. In respiratory tract infection in mice due to Klebsiella pneumoniae EB4O, CTRZ/CV was more erective than CCLO, CRXMA and AMXCCV and also more efficacious than CCLO, CRXMA and AMXCCV in urinary tract infection in mice due to Escherichia coli EB13. These results indicate that CTRZ/CV is a useful drug for the treatment of infection caused by $\beta$-1actamase-producing strains including ESBL-producing strains.

The quinolones are broad-spectrum antibiotics and enhanced antimicrobial activity has extended the use of the quinolones beyond the traditional indications for quinolone antibiotics in the treatment of urinary tract infections. The quinolones are effective in a wider variety of infectious diseases, including skin and respiratory infections. Because of their excellent safety and tolerability, they have become popular alternatives to penicillin and cephalosporin derivatives in the treatment of various infections. A retrospective study was performed to evaluate efficacy and safety of IV quinolones for inpatient use. Total 117 patients who administerd quinolones for longer than 3 continuous days at community hospital from October 1st, 2008 to December 31st, 2008 were reviewed. The criterias for drug evaluation were included the validation of indication, outcome, dosage and side effects. In the results, ciprofloxacin 13 (total 93), levofloxacin 3 (total 59) and moxifloxacin 2 (total 19) cases were not met the criterias based on the culture results. Major indications were pneumonia (ciprofloxacin 16.3%, levofloxacin 67.8%, moxifloxacin 84.2%), urinary tract infection (ciprofloxacin 44.1%), skin infection (ciprofloxacin 7.5%, levofloxacin 20.3%, moxifloxacin 10.5%), intra-abdominal infection (ciprofloxacin 10.8%, moxifloxacin 5.3%), etc.. In the results of quinolone monotherapy, the frequencies were each ciprofloxacin 74.2%, levofloxacin 50.8% and moxifloxacin 47.4%. In the results of dosage validation, the validities were each ciprofloxacin 54.8%, levofloxacin 94.9% and moxifloxacin 100.0%. In the results of duration validation, the validities were each ciprofloxacin 59.1%, levofloxacin 78.0% and moxifloxacin 89.5%. Adverse drug reactions were reported for total 49 cases and those were gastrointestinal tract effects including nausea, vomiting, diarrhea and central nervous system effects including headache, dizziness. In summary, the quinolones appropriately used for hospitalized patients based on this study. A focused approach emphasizing "correct use of quinolones" may reduce development of antimicrobial resistance and maximize class efficacy. Consequently, correct use of antibiotics will contribute to decrease medical expenses for person and community.

The pharmacokinetics of DWP20364 (1-cyclopropyl -5-amino-6,8-difluoro-7-(2,7-diazabiclo [3,3,0] oct-4-ene-7-yl)-1,4-dihydro-4-oxoquinoline-3-carboxylic acid), a novel fluoroquinolone containing C7-bicyc-talc structure, were compared with those of ciprofloxacin (CPFX) after single intravenous (i.v.) and oral (p.o.) administration to rats using microbiological assay (bioassay). After i.v. administration to rats, the plasma concentrations of the two drugs declined biexponentially. The terminal half-lives (t$_{1}$2$\beta$/) of DWP20364 were 110$\pm$ 13.2 min and 117$\pm$3.09 min after i.v. and p.o. administration, respectively, and they were significantly higher than those of CPFX (45.5$\pm$9.52 min and 48.3$\pm$ 12.1 min, respectively). Similar results were also obtained from plasma concentrations and area under the plasma concentration-time curves. The total body clearance of DWP20364, 7.82$\pm$0.37 ml/min/kg was significantly slower than that of CPFX, 27.3 $\pm$ 11.1 m1/ min/kg. Above data suggested that the antimicrobial activity of DWP20364 could be longer than that of CPFX. The urinary recovery after i.v. and p.o. administration of DWP20364 was significantly lower than those of CPFX suggesting that the effect of DWP20364 on urinary tract infection could be lower than that of CPFX. The serum protein binding values of DWP20364 at 2$\mu$g/ml were apparently 91.5~93.1% in rats and human. DWP20364 was distributed by the order of liver, lung, kidney, sf)leon, heart, muscle and brain collected at 30 min after orally administered.

요석증은 비뇨기과에서 흔히 관찰되는 질환으로서 30∼50대에 많이 발생하고, 남자가 여자보다 발생빈도가 높고, 좌측보다는 우측이 많으며, 문화가 발달한 나라에서는 상부요로 결석이 많으나 후진국에서는 하부요로 결석이 많다. 결석성분은 수산칼슘, 인산칼슘, 인산마그네슘암모늄, 요산, 시스틴 결석과 그들의 혼합결석으로 분류된다. 병태 생리학에 따르면, 결석의 발생원인은 요중의 무기질 농도가 과포화 상태가 되면 결정체핵이 생성된다는 과포화/결정체설, 기질관여설, 억제물질의 결핍설, 에피택시설 등이 있고, 상피소체기능항진중, 과칼슘뇨증, 과요산뇨증, 과수산뇨증, 시스틴뇨증 외에도 원위세뇨관 산증, 과비타민 D증, 소화기계 질환이 통계적으로 유의성 있게 관여된다는 것이다. 본 연구에서는 미란성 위염 환자 K43에서 화학분석법, 적외선 흡수 분석법, image analysis법을 사용하여 재발성 상부요로 결석성분을 분석한 결과 제2 수산칼슘과 인산칼슘의 혼합결석으로 확인되었고, 혈액화학 검사와 요 검사 등 임상검사 성적은 정상치를 유지하고 있었다. 따라서 K43의 재발성 요로결석은 보고된 생성원인이나 인자들에 대한 통계수치와는 연관성이 없었으며 미란성 위염으로부터 영향을 받았다는 증거도 없었다.
