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 report the outcomes of clinical analysis on the negative culture rate of normal ocular surface flora and the anterior chamber penetration after the preoperative prophylactic use of 0.3% tosufloxacin ophthalmic solution. METHODS: From July 2010 to June 2012, 38 eyes of 38 patients who were scheduled to receive intravitreal injection or cataract surgery were examined for bacterial culture positive rate using conjunctival scraping. The patients were treated with 0.3% tosufloxacin eyedrops preoperatively 5 times a day for 2 days before surgery. After the treatment, the bacterial culture negative rate based on conjunctival scraping was assessed to evaluate the drug efficacy. Of the 38 patients, 19 had cataract surgery. The concentration of tosufloxacin at anterior chamber was assessed in the 19 patients. Additionally, any side effects from the drug were monitored during the treatment. RESULTS: Among the 38 eyes, 21 eyes showed a bacterial culture positive rate before treatment. After the drug treatment, the bacterial culture negative rate was 57.1% (12/21). Coagulase-negative staphylococci were most frequently cultured in 15 (39%) of the 38 eyes before treatment and the negative rate of bacterial culture was 86.7% (13/15) after treatment. Average antibiotic residue concentrations in aqueous humor was 0.050 +/- 0.038 microg/mL. No side effects from the drug were reported during the experimental period. CONCLUSIONS: Although the 0.3% tosufloxacin eyedrops were not effective in all bacterial strains and showed relatively low penetration rate into the anterior chamber, they were effective in some gram positive organisms, particularly in coagulase-negative staphylococci of normal ocular surface flora.

PURPOSE: Although most surgeons generally administer prophylactic antibiotics for more than three days, the optimal duration of antimicrobial prophylaxis in elective gastric surgery is still open to debate. The aim of this study was to determine if the duration of prophylactic antibiotic use can affect the recovery of patients after elective gastric surgery. MATERIALS AND METHODS: A total of 93 patients with gastric cancer were enrolled in this study, between January 2007 and December 2007. Patients were excluded if they had an infection at the time of surgery or they underwent an emergency operation. The first antibiotics were commonly given from just prior to the operation. The patients were divided into three groups according to the operation periods: those who received antibiotics only on the day of operation (arm A), those who received antibiotics for up to 3 days (arm B), and those who received antibiotics for more than 5 days postoperatively (arm C). The antibiotic that was used was second generation cephalosporin. RESULTS: The rate of surgical site infection was 12.9% (n=4) in arm A, 16.1% (n=5) in arm B and 19.4% (n=6) in arm C, respectively (P=0.788). No relationship was observed between the duration of prophylaxis and the rate of fever or the neutrophil counts during postoperative 7 days (P=0.119, P=0.855). CONCLUSION: The prophylactic effect of antibiotics on recovery, with the antibiotics being received only on the day of the operation, is as effective as receiving antibiotics for a longer duration after gastric cancer surgery.

The incidence of transient bacteremia following esophageal variceal sclerotherapy (EVS) was evaluated in 29 patients. These 29 patients underwent a total of 83 sclerotherapy sessions.Prior to EVS, all instruments were sterilized. Blood cultures were drawn pre-EVS and post-EVS.All pre-EVS and post-EVS blood cultures were negative. In conclusion, it was found bacteremia following sclerotherapy is not easily developed, if a vigorous approach of using well cleaned equipment is used. Unless there is a cardiac prothesis or valvular heart disease, antibiotic prophylaxis is not warranted.

Vertebroplasty and kyphoplasty are well-known, useful techniques for the treatment of painful vertebral compression fractures. Although the risk associated with these procedures is low, serious complications can occur. Of these complications, infection is even rarer, however, when it does occur, it is difficult to manage and can become life-threatening. We describe here a case of infectious spondylitis with epidural inflammation that occurred after performing kyphoplasty in a patient who had a thoracic vertebra compression fracture. We reviewed other case and literatures. Extreme asepsis of the operating theater, screening and treatment for systemic infection prior to the procedure, as well as the use of appropriate antibiotic prophylaxis are strongly recommended when conducting kyphoplasty to prevent infection.

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.

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."

The jejunum is the longest part of the small intestine and its lumen is mainly involved in the absorption of the nutrients. The present study was conducted to evaluate the effects of metronidazole, ceftriaxoine sodium and their combination on the stenotic index of the end to end jujunal anastomotic site. To accomplish this, 20 healthy stray dogs were subjected to end to end jejunal ansastmosis. Dogs in Group A (control) underwent jejunal anstomosis with no antibiotic prophylaxis, while those in Group B received surgery and metronidazole alone at 50 mg/kg, those in Group C received ceftriaxone sodium intravenously at 30 mg/kg body weight prior to surgery and dogs in Group D were given metronidazole in combination with ceftriaxone sodium at 50 mg/kg and 30 mg/kg, respectively, 2 h before surgical intervention. No significant difference (p > 0.05) in the stenotic index was observed at 14 days after jejunal anastomosis. These findings indicate that prophylactic administration of metronidazole and ceftriaxone sodium alone or in combination had no significant effect on the stenotic index of the jejunum.
