Background and Objective: Antibiotic prophylaxis is used to prevent bacterial infections and rebleeding in cirrhosis patients with upper gastrointestinal bleeding (UGIB). However, the effects of various antibiotics on patients with UGIB are still being considered. This study aims to evaluate the effect of antibiotic prophylaxis on cirrhosis patients with UGIB. Methods: The studies were searched through databases of PubMed, ScienceDirect, Wiley Online Library, and CENTRAL from 2013 to 2023. We used Revman 5.4 to perform a meta-analysis. I2 statistics measured the heterogeneity test. The odds ratio (OR) and 95% confidence interval (CI) were used to assess the effect of antibiotic prophylaxis. Results: Twelve studies involving 14,825 cirrhosis patients were included in this study. Based on the meta-analysis, antibiotic prophylaxis significantly lowered the bacterial infection rate (OR: 0.29, 95%CI: 0.10 to 0.84, P = 0.02), and the incidence of serious adverse events (SAE) (OR: 0.50, 95%CI: 0.28 to 0.88, P = 0.02) in cirrhosis patients with UGIB. Conclusions Administration of antibiotics demonstrated a significant reduction in bacterial infection rates and SAEs. Broad-spectrum non-absorbable antibiotics can be used in cirrhosis patients with UGIB. The appropriate use of antibiotics is important to prevent resistance.

PURPOSE: To evaluate practice patterns for pediatric hydronephrosis of Korean urologists practicing at secondary or university hospitals. MATERIALS AND METHODS: The subjects were asked to complete questionnaires sent by postal mail or e-mail that explored practicing diagnostic and therapeutic strategies in the management of pediatric hydronephrosis and ureteropelvic junction obstruction. The questionnaires of those responding were analyzed according to whether the respondent practiced at a secondary or university hospital, how long they had been urologists, and whether they specialized in pediatric urology or other specific field of urology. RESULTS: Of the 354 questionnaires sent, 97 were returned (response rate 27.4%). Voiding cystourethrography was not routinely recommended by 95.7% of respondents, and diuretic renal scanning was considered necessary for postnatal evaluation of prenatal hydronephrosis by 78.5%. In addition, 72.2% of these doctors did not routinely recommend antibiotic prophylaxis. Follow-up ultrasonography was recommended at 3 to 6 months (61.1%), and follow-up diuretic renal scanning was recommended at 3 to 6 months (38.6%) or 6 to 12 months (32.7%). The reported length of time it took to deem an operation as a success was 3 to 6 months (49.5% and 60.7%) and within 3 months (34.1% and 19.1%) by ultrasonography and diuretic renal scanning, respectively. CONCLUSIONS: This survey documented a certain degree of variability among Korean urologists concerning standard practices of the assessment, follow-up, and treatment for pediatric hydronephrosis. Results from this survey might contribute useful data for establishing proper guidelines for the management of pediatric hydronephrosis.

OBJECTIVE: The risk of complications is high for patients with a large cranial defect and hydrocephalus, undergoing cranioplasty and ventriculoperitoneal (VP) shunt operation. The purpose of this study is to examine retrospectively such cases with complications and contrive an operative technique to reduce complications. METHODS: Nineteen patients underwent cranioplasty and VP shunt operation due to large cranial defects and hydrocephalus. These patients were divided into two groups: Group A with 10 patients who underwent staged-operations, and Group B with 9 patients who underwent one-stage operation. Their complications in each group were retrospectively reviewed. Another five patients underwent a one-stage operation with temporary occlusion of the distal shunt catheter to improve on the technique and were categorized as Group C. Complications in these groups were compared and analyzed. RESULTS: The results of the data analysis revealed that complications related to anesthesia (40%) and those related to antibiotic prophylaxis (30%) were high in Group A, while non-infectious delayed complications (45%) and perioperative complications such as intracranial hematoma (33%) were high in Group B. However, for patients in Group C, it showed less complication with the operative technique devised by these authors, as opposed to two previous procedures. CONCLUSION: In patients with hydrocephalus and a large cranial defect, complications arising from existing one-stage operation or staged-operations can be reduced by implementing the technique of "one-stage operation with temporary occlusion of the distal shunt catheter."

PURPOSE: We investigated the relationship of vesicoureteral reflux (VUR) and renal scarring in children who were treated surgically due to failure of initial medical management. MATERIALS AND METHODS: Thirty two children (51 renal units), 15 boys and 17 girls, aged 1-8 (median 3.2) years, with VUR were analyzed retrospectively. All children were initially treated with antibiotic prophylaxis for median 15.2 months (10-19 months). In 51 renal units, reflux grade at presentation was grade II in 8, III in 14, IV in 25 and V in 4. Renal scars were evaluated with dimercaptosuccinic acid (DMSA) scan and classified into three grades. We analyzed the incidence and severity of renal scar according to various clinical characteristics and discussed the optimal treatment in vesicoureteral reflux with respect to the development of renal scar. RESULTS: DMSA scan revealed that 69% (35/51) of the renal units had renal scars. Scarring at presentation was grade I in 10, II in 20 and III in 5 renal units. The incidence of renal scar was 86% at ages less than 2 years, 72% at ages 2 to 5 and 27% at ages greater than 5, of which the difference was statistically significant. And the incidence of renal scar according to the reflux grade was 38% in II, 50% in III, 84% in IV and 100% in V, of which the differnce was also statistically significant. However, the sex and laterality did not affect the incidence of renal scar in this study. With respect to the scar grade, the grade of refux was the only statistically significant determining factor. Especially, grade IV reflux resulted in much more severe scarring than grade III reflux. Comparing the result of DMSA scan at presentation with that just before operation in 13 children (18 renal units), only two renal units with grade IV reflux showed increase in renal scar. CONCLUSIONS: The most important factor to affect the development and severity of renal scar was the reflux grade. Considering relatively higher incidence of renal scar and more severe scarring in grade IV reflux than grade III reflux, early surgical management may be a possible option in the treatment of children with grade IV reflux.

PURPOSE: This study compared the frequency of postoperative infections in patients for a closed mandibular fracture with that without the ostoperative antibiotic prophylaxis. Patients and Methods: 48 patients without any specific medical history were divided into two groups depending on whether or not antibiotics had been applied after the surgery. The 24 patients in group 1 received only a second-generation cephalosporin (Cefotetan(R)) ntravenously from admission to immediate after the surgery. Likewise, 24 patients in group 2 received 1.0g of Cefotetan(R) twice daily longer than the third day after surgery. The mean (SD) duration of antibiotics administration after surgery was 6.9 (+/-3.56). The patients were evaluated after surgery for any postoperative infections according to the criteria: purulent drainage from a wound, spontaneous wound dehiscence accompanied by swelling, pain, and fever around the wound. RESULTS: Postoperative infections were encountered in 2 out of 24 patients in group 1, who received antibiotic medication until shortly after surgery, and in 3 out of the 24 patients in group 2, in whom the medication was continued even after the surgery. There was no sig nificant difference in the incidence of postoperative infections between the two groups. CONCLUSION: From this study, postoperative use of antibiotics seems to be unnecessary with view of the little significance of the factors that could affect the wound infection.

Endoscopic treatment is a minimally invasive treatment for managing patients with vesicoureteral reflux (VUR). Although several bulking agents have been used for endoscopic treatment, dextranomer/hyaluronic acid is the only bulking agent currently approved by the U.S. Food and Drug Administration for treating VUR. Endoscopic treatment of VUR has gained great popularity owing to several obvious benefits, including short operative time, short hospital stay, minimal invasiveness, high efficacy, low complication rate, and reduced cost. Initially, the success rates of endoscopic treatment have been lower than that of open antireflux surgery. However, because injection techniques have been developed, a recent study showed higher success rates of endoscopic treatment than open surgery in the treatment of patients with intermediate- and high-grade VUR. Despite the controversy surrounding its effectiveness, endoscopic treatment is considered a valuable treatment option and viable alternative to long-term antibiotic prophylaxis.
