RESUMO
PURPOSE: We identify which nonantibiotic strategies could reduce the risk of infectious complications following prostate biopsy. MATERIALS AND METHODS: We performed a literature search on MEDLINE®, Embase® and the Cochrane Database for randomized controlled trials (inception to May 2020) assessing nonantibiotic interventions in prostate biopsy. Primary outcome was pooled infectious complications (fever, sepsis and symptomatic urinary tract infection) and secondary outcome was hospitalization. Cochrane risk of bias tool and GRADE approach were used to assess the bias and the certainty of evidence. The study protocol was registered with PROSPERO (CRD42015026354). RESULTS: A total of 90 randomized controlled trials (16,941 participants) were included in the analysis, with 83 trials being categorized into one of 10 different interventions. Transperineal biopsy was associated with significantly reduced infectious complications as compared to transrectal biopsy (RR 0.55, 95% CI 0.33-0.92, p=0.02, I2=0%, 1,330 participants, 7 studies). Rectal preparation with povidone-iodine was also shown to reduce infectious complications (RR 0.50, 95% CI 0.38-0.65, p <0.000001, I2=27%, 1,686 participants, 8 studies) as well as hospitalization (RR 0.38, 95% CI 0.21-0.69, p=0.002, I2=0%, 620 participants, 4 studies). We found no difference in infectious complications/hospitalization for 6 other interventions, ie number of biopsy cores, periprostatic nerve block, number of injections for periprostatic nerve block, needle guide type, needle type and rectal preparation with enema. In 2 interventions (needle diameter, rectal preparation with chlorhexidine) meta-analysis was not possible. Finally, 7 studies had unique interventions. The certainty of evidence was rated as low/very low for all interventions. CONCLUSIONS: Transperineal biopsy significantly reduces infectious complications compared to transrectal biopsy and should therefore be preferred. If transrectal biopsy is performed, rectal preparation with povidone-iodine is highly recommended. The other investigated nonantibiotic strategies did not significantly influence infection and hospitalization after prostate biopsy.

BACKGROUND & AIMS: Sarcopenia is considered a risk factor of postoperative complications among patients undergoing abdominal surgery. However, few studies have demonstrated an effective strategy for reducing complications in sarcopenic patients. This study aimed to examine retrospectively the effect of preoperative immunonutrition on postoperative complications, especially infectious complications, in low skeletal muscle mass patients undergoing pancreaticoduodenectomy (PD). METHODS: This was a retrospective, consecutive cohort study conducted in our institution. Skeletal muscle mass was assessed using preoperative computed tomography images in 298 consecutive patients who underwent PD between May 2009 and May 2016. Cross-sectional areas at the third lumbar vertebrae normalized for stature (cm2/m2) were defined as the skeletal muscle mass index (SMI). Low SMI was defined as the lowest sex-specific quartile of SMI. Risk factors for postoperative infectious complications and the effect of preoperative immunonutrition on low SMI patients who underwent PD were evaluated. RESULTS: Results of multivariate analysis showed that the presence of low SMI and absence of preoperative immunonutrition were independent risk factors for postoperative infectious complications after PD (odds ratio [OR], 3.17 and 3.10, respectively; P < 0.001). In high SMI patients, the rate of postoperative infectious complications was significantly lower in those who received immunonutrition than in those who did not receive immunonutrition (31.9 vs. 46.1%, respectively; OR, 1.82; P = 0.045). Further, similar findings were exhibited in low SMI patients (26.3 vs. 83.6%, respectively; OR, 14.31; P < 0.001), even though OR was markedly higher in low vs. high SMI patients. CONCLUSION: There is a stronger association with reduced infectious complications in patients who have low SMI and receive immunonutrition (UMIN-CTR Identifier: UMIN000035775.).

BACKGROUND: Transurethral resection of the prostate (TUR-P) is one of the most frequent routine procedures in urology. Because of the semisterile environment, postoperative infections, including sepsis, are a common complication, with Escherichia coli, Klebsiella spp., Proteus mirabilis or Enterococcus faecalis as frequently isolated pathogens. Facklamia hominis is a gram-positive, facultatively anaerobic, alpha-hemolytic, catalase-negative coccus that was first described in 1997. To date, only a few cases of infectious complications have been described. We report the first case of postoperative bacteremia due to Facklamia hominis after TUR-P. CASE PRESENTATION: An 82-year-old man developed fever only a few hours after elective TUR-P because of benign prostate syndrome. After cultivation of blood cultures, antibiotic therapy with ceftriaxone was intravenously administered and changed to oral cotrimoxazole before discharge of the afebrile patient. One anaerobic blood culture revealed Facklamia hominis. Under antibiotic therapy, the patient remained afebrile and showed no signs of infections during follow-up. CONCLUSIONS: Fever and bacteremia are frequent complications after TUR-P. This study is the first report of Facklamia hominis in a postoperative blood culture after TUR-P. To date, there are only a few reports of patients with infectious complications and isolation of Facklamia hominis in various patient samples. Because Facklamia hominis resembles viridans streptococci on blood agar analysis, this pathogen may often be misidentified. In this case identification of Facklamia hominis was possible with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. It has been postulated that Facklamia hominis might be a facultative pathogen and that its incidence will increase in the future.

BACKGROUND: Sepsis is a severe complication following transrectal ultrasound-guided prostate biopsy (TRUSPBx). Ciprofloxacin is commonly used for prophylaxis; however, there is an increasing incidence of resistant enteric organisms worldwide. OBJECTIVE: To investigate the effect of a targeted prophylactic antimicrobial regimen based on rectal swab cultures in reducing the rate of sepsis. DESIGN, SETTING, AND PARTICIPANTS: A total of 1012 patients were included. Group A (609 patients) received an empirical prophylactic antimicrobial regimen of gentamicin, metronidazole, and ciprofloxacin. Targeted antimicrobial prophylaxis was introduced due to significant ciprofloxacin and gentamicin resistance in patients admitted with sepsis following TRUSPBx. The remaining 403 patients (Group B) had rectal swab cultures performed prior to biopsy. Patients with organisms resistant to ciprofloxacin or gentamicin received a targeted prophylaxis regimen of fosfomycin, amikacin, and metronidazole. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We retrospectively collected and analysed data on sepsis and bacteraemia for all patients as well as data on rectal swab culture, recent foreign travel, and recent antibiotic use for patients in Group B. RESULTS AND LIMITATIONS: In group A, 12 (2.0%) patients developed sepsis following TRUSPBx, while in group B, 9 (2.2%) patients developed sepsis despite targeted prophylaxis (p=0.82). Patients with ciprofloxacin-resistant rectal flora had a significantly higher rate of sepsis (9.1% vs 1.1%; p=0.003). There was a reduction in patients admitted with bacteraemia and severe sepsis between group A (1.2%) and group B (0.3%) which did not reach statistical significance (p=0.16). In group B, 55 of 403 (13.6%) patients had ciprofloxacin-resistant rectal flora, while 66 (16.4%) had organisms resistant to both ciprofloxacin and gentamicin. A recent foreign travel history was associated with an increased incidence of ciprofloxacin-resistant rectal flora (23.6% vs 10.8%; p=0.007). The main limitations of our study include its retrospective nature and potential under-reporting of less severe infectious complications. CONCLUSIONS: Rectal swab cultures identify patients with ciprofloxacin-resistant rectal flora who have an eight-fold risk of sepsis. Targeted antimicrobial prophylaxis may not be beneficial in reducing the sepsis rate when compared with augmented empirical prophylaxis. In an era of increasing antimicrobial resistance, transperineal prostate biopsies should be considered to reduce the risk of infective complications. PATIENT SUMMARY: Performing rectal swab culture prior to transrectal prostate biopsy can help identify patients at risk of developing sepsis despite targeted prophylactic antibiotics.

To analyze the occurrence of resistant bacterial infection in patients undergoing cardiac surgery hospitalized in the surgical specialty hospital, in Erbil city, Iraq. A prospective study was done on a total of 138 patients operated and hospitalized in an intensive care unit and surgical wards. Bacterial isolates identification was done according to cultural characteristics, microscopic examination, some biochemical tests, analytic Profile Index 20E& API Staph, confirmed with VITEK® 2 compact system (BioMérieux). Antimicrobial susceptibility for disc diffusion tested to 17 antimicrobial agents. Resistance isolates were confirmed phenotypically for carbapenemase by Rapidec Carba NP Test (bioMe´rieux SA, Marcy-l'E´toile, France) for ESBLs producers by ESBL screening test VITEK 2 system. Molecularly blaIMP blaTEM, blaKPC, AmpC and blaCTX-M were detected by PCR. In 134 patients, 28.3% of patients got infected post-operatively. The most frequent source of isolation was from ICU patients (75%). Isolated bacteria included gram-positive 29 (54.7%) and gram-negative bacteria 24 (45.3%). Most frequently: Staphylococcus aureus (24.4%), each of pseudomonas aeroginosa, Klebsiella pneumonia (15.1%), Streptococcus spp. (11.3%), Escherichia coli (9.4%). Whereas included Coagulase Negative Staphylococci species (CoNS) (13.2%) and Enterococci species (5.7) Statistical analysis showed significantly higher sensitive isolates as compared with resistance isolates. Resistance to Carbapenems calss was 18.9% and Cephalosporins class 41.5% of isolates. The antimicrobial resistance pattern indicated that MDR bacterial isolates (81.1%) were widespread. Of the 34 phenotypically ESBL positive isolates, the ESBL genes (AmpC, blaCTX-M, and blaTEM) were amplified in 7(20.6), 6(17.6) and 6(17.6) isolates respectively. Out of 8 K. pneumonia (37.5%) harboring both blaAmpC and bla-CTX-M genes, while 6(75%) carries blaTEM. The blaCTX-M gene was found in only 1 (12.5%) out of 8 isolates of P. aeruginosa. While blaAmpC genotyping revealed that 1(7.7%) out of 13 Staph. aureus isolates were harboring it. Finally, 3(60%) out of 5 E. coli isolates harboring both AmpC and bla-CTX-M genes. Cardiac surgery patients wound show increasingly emerging strains of ESBL-producing gram-negative bacteria K. pneumonia, P. aeruginosa and E. coli especially patients prolonged in the intensive care unit.

There have been no case reports of thoracic subcutaneous abscess after surgery for Mycobacterium abscessus complex associated empyema. We herein report a case of Mycobacterium abscessus subsp. abscessus (M. abscessus subsp. abscessus) induced subcutaneous abscesses following surgical treatment for concurrent M. abscessus subsp. abscessus -associated empyema and pneumothorax. A 75-year-old woman had M. abscessus subsp. abscessus -associated empyema and pneumothorax. She underwent surgical treatment of decortication and fistulectomy and suffered from M. abscessus subsp. abscessus -associated subcutaneous abscesses after thoracentesis/drainage. A multidisciplinary approach combined with surgical care, thermal therapy, and multidrug chemotherapy contributed to a successful result. An early multidisciplinary approach is believed to be important in cases of M. abscessus subsp. abscessus -associated empyema and subcutaneous abscess.

PURPOSE: In postoperative peritonitis, Gram stain examination (GSE) of peritoneal fluid has been proposed as a guide for the prescription of glycopeptides and antifungal therapy in empirical antibiotherapy. No data support this approach for Gram-positive cocci. We aimed to evaluate the performance of GSE in predicting the results of the culture of peritoneal fluid. METHODS: In this retrospective single-center study, concordance between GSE and culture of peritoneal fluid was assessed for different types of microorganisms. Factors associated with concordance of the two tests were evaluated in the subpopulation of Gram-positive cocci peritonitis. RESULTS: Among the 152 episodes, the GSE was negative in 57 cases. The negative predictive value and the positive predictive value were 41% and 87% for Gram-positive cocci (GPC), 31% and 86% for Gram-negative bacilli, and 78% and 94% for fungi. GSE is not a reliable guide for the choice of empirical antibiotherapy and cannot reliably rule out the presence of GPC at culture. If we aim to achieve a high rate of adequacy, the systematic use of glycopeptide in the empirical antibiotherapy may be considered. CONCLUSION: GSE shows poor performance to predict the results of culture of peritoneal fluid in postoperative peritonitis. Avoiding covering resistant GPC cannot be based on the result of GSE.

BACKGROUND: Acute postoperative peritonitis resulting from previous abdominal surgery is still a severe and potentially fatal disease, which is associated with high morbidity and mortality. The aim of the present study was to evaluate patients' outcome after postoperative peritonitis and identify the most effective empiric antibiotic regimes. METHODS: 422 patients with acute postoperative peritonitis as a result to earlier abdominal operation (e.g. anastomotic leakage) were analyzed retrospectively focusing on the origin of the peritonitis, microbial flora and resistance patterns. Furthermore, mortality was estimated according to sensitivity results of the tested antibiotics. RESULTS: In 50% of the patients, anastomotic leakage was located in the colon. The predominantly cultured microorganisms were Escherichia coli and Enterobacteriaceae. The combination of meropenem and vancomycin was effective in 96% of these microbes. The frequently used combinations of piperacillin/sulbactam and cefotaxime/metronidazole were effective in only 67% and 43%, respectively. CONCLUSIONS: We were able to show that the currently used antibiotic regimes with piperacillin/sulbactam and cefotaxime/metronidazole are ineffective in a relevant number of patients with anastomotic leakage. Only meropenem or meropenem/vancomycin cover most of the microbes predominant in postoperative peritonitis.

Solid organ transplantation (SOT) is the best treatment option for end-stage organ disease. Newer immunosuppressive agents have reduced the incidence of graft rejection but have increased the risk of infection, particularly due to the reactivation of latent infections due to opportunistic agents such as Mycobacterium tuberculosis. Active tuberculosis (TB) after SOT is a significant cause of morbidity and mortality. Most cases of posttransplant TB are secondary to reactivation of latent tuberculosis infection (LTBI) due to the effects of long-term immunosuppressive therapy. Risk minimization strategies have been developed to diagnose LTBI and initiate treatment prior to transplantation. Isoniazid with vitamin B6 supplementation is the treatment of choice. However, liver transplantation (LT) candidates and recipients have an increased risk of isoniazid-induced liver toxicity, leading to lower treatment completion rates than in other SOT populations. Fluoroquinolones (FQs) exhibit good in vitro antimycobacterial activity and a lower risk of drug-induced liver injury than isoniazid. In the present review, we highlight the disease burden posed by posttransplant TB and summarize the emerging clinical evidence supporting the use of FQs for the treatment of LTBI in LT recipients and candidates.

OBJECTIVE: To evaluate the incidence, clinical presentation and factors associated with the development of urinary sepsis after performing ureterorenoscopy. MATERIAL AND METHODS: Retrospective study of patients undergoing ureterorenoscopy for the treatment of lithiasis between July 2015 and October 2017. Patients who developed urinary sepsis during the 30 days following the intervention were identified. Personal, clinical, surgical and microbiological backgrounds were collected. Statistical analysis was performed with the Chi squared test (or Fisher's exact test), Student's t (or U Mann-Whitney) or logistic regression as appropriate. RESULTS: 246 ureterorenoscopies were performed, 184 (74.8%) on ureteral stones and 62 (25.2%) on kidney stones, with a mean age of 52 (44.5-59.5) years. After procedure, 18 (7.3%) patients developed urinary sepsis, 10 of them (55.5%) occurred in the first 24h. The urine culture showed enterobacteria (61.1%) and enterococci (38.9%). The antibiogram showed greater sensitivity to nitrofurantoins (100%) and quinolones (72%). The statistical analysis showed that female sex, the clinical debut of urolithiasis as urinary sepsis, having received antibiotic or having required urinary diversion by a double J during debut, positive presurgical uroculture and the persistence of residual lithiasis after surgery were significantly associated (P<.05) with the development of urinary sepsis after ureterorenoscopy. CONCLUSION: Urinary sepsis is a complication that appears after performing ureterorenoscopy, especially in female patients with a history of urinary sepsis, antibiotic therapy, double J, previous positive urine culture or residual lithiasis after the procedure.

BACKGROUND: Osteomyelitis was determined in two patients following radiofrequency turbinoplasty. This is a rare complication of the procedure, and we have found no other case reports concerning osteomyelitis as a specific complication of radiofrequency turbinoplasty. CASE PRESENTATION: Two patients underwent radiofrequency turbinoplasty. Postoperatively they presented with clinical features such as a faecal smell in the nose, crusting and local necrosis of the inferior turbinates, which led to the clinical and histological diagnosis of osteomyelitis. The infections were polymicrobial, as verified by bacterial growth in the nasal biopsies. They were treated with surgical debridement, local and systemic antibiotics and nasal saline irrigation. INTERPRETATION: The patients underwent surgery that involved the use of more insertion channels than recommended by the distributor of the surgical equipment, and local anaesthesia included adrenaline. These two factors may well have caused or increased the likelihood of developing osteomyelitis. One patient has an open nose giving rise to no concern after treatment; the other patient has developed empty nose syndrome on the right side. We report these cases in order to raise and aid awareness regarding this possible complication of radiofrequency turbinoplasty.

OBJECTIVES: To investigate whether switching ciprofloxacin to fosfomycin in the case of fluoroquinolone-resistant rectal bacteria influences the incidence of infectious complications after transrectal prostate biopsy. METHODS: From December 2015 until December 2017, patients undergoing prostate biopsy were randomly assigned to a control group or an intervention group in a prospective, open-label fashion at three different centers. The presence of fluoroquinolone-resistant organisms was detected by rectal swabs. Patients in the control group received ciprofloxacin. Patients in the intervention group received fosfomycin instead of ciprofloxacin in the case of fluoroquinolone-resistant bacteria on rectal swab culture. The primary end-point was the difference in occurrence of major (febrile) and minor (afebrile) infections between both groups. RESULTS: A total of 102 patients were randomized to the control group, and 102 patients to the intervention group. In the control group, nine complications occurred, of which five were major febrile complications. In the intervention group, six complications occurred, of which four were major febrile complications. The total number of complications (major and minor) did not differ between both groups (P = 0.59). A subgroup analysis of patients with fluoroquinolone-resistant bacteria on rectal swab showed five complications in the control group and one complication in the intervention group (P = 0.09). CONCLUSIONS: This represents the first prospective randomized study using rectal cultures for targeted antibiotic prophylaxis. Study findings show promising results for use of fosfomycin in patients with fluoroquinolone resistance.

There have been various cases of salmonella osteomyelitis reported in sickle cell anemia. We present a case of emphysematous osteomyelitis caused by Salmonella typhi in a 29-year-old beta thalassemia major patient. Diagnosis of emphysematous osteomyelitis was confirmed by computed tomography and magnetic resonance imaging, and culture of pus drained during surgical debridement confirmed the causative microorganism, Salmonella typhi. Antimicrobials were given according to microbiological sensitivity for a period of 8 weeks. Our patient also received hyperbaric oxygen therapy. At the end of therapy, he was afebrile and laboratory parameters normalized with a residual joint deformity which developed within 3 months.

Background: Wounds are commonly encountered in the clinical practice. Microbacterial colonization and infection negatively affect wound outcomes. With increasing emergence of antibiotic-resistant strains, it is essential to determine local patterns of wound microbiological profile and antibiotic susceptibility to guide rational empirical antibiotic use. Materials and Methods: Consecutive patients who presented to the plastic surgery unit were recruited to the study over a 6-month period. Wound swab cultures were performed at presentation using standard protocols and media. The wound swab was performed by the Levine technique and data were analyzed using a statistical software package. Results: Eighty-five microbial isolates were obtained from the eighty patients (55 males and 25 females) recruited. Gram-positive isolates were 35 (41.2%) and Gram-negative were 50 (58.8%). There was equal distribution of acute and chronic wounds. Pseudomonas aeruginosa was the most common isolate at 30.6%, followed by Staphylococcus aureus (27.1%), Escherichia coli (9.4%), Streptococcus species (8.2%), and Morganella morganii (7.1%). The isolates demonstrated resistance to amoxicillin-clavulanate, ampicillin, cloxacillin, cefuroxime, ceftazidime; low-to-moderate sensitivity to erythromycin, gentamicin, streptomycin, tetracycline, ciprofloxacin, and ofloxacin; and a moderate sensitivity to ceftriaxone and a high sensitivity to imipenem. There was significant difference in antibiotic resistance patterns between Gram-positive isolates from acute and chronic wound infections but not for acute and chronic wound Gram-negative isolates. Conclusion: Most of the microbial isolates, particularly the Gram-negative isolates demonstrated low sensitivity to commonly used antibiotics and moderate-to-high sensitivity to less commonly used newer antibiotics.
RésuméContexte: Les plaies sont généralement rencontrés dans la pratique clinique. La colonisation et l'infection Microbacterial négatif sur blessure Les résultats. Avec l'augmentation de l'émergence de souches résistantes aux antibiotiques, il est essentiel de déterminer les tendances locales de plaie profil microbiologique Sensibilité aux antibiotiques et de guider l'utilisation d'antibiotiques empiriques rationnelle. Matériel et méthodes: Patients consécutifs qui ont présenté à la Unité de chirurgie en plastique ont été recrutés pour l'étude sur une période de 6 mois. Écouvillon blessure cultures ont été effectuées à la présentation en utilisant des protocoles standard et des médias. L'écouvillonnage de la plaie a été effectuée par la technique de Levine et les données ont été analysées à l'aide d'un logiciel statistique. Résultats: Quatre-vingt-cinq isolats microbiens ont été obtenues à partir de 80 patients (55 hommes et 25 femmes) recrutés. Les isolats Gram-positives ont été 35 (41,2%) et Gram-négatives sont 50 (58,8%). Il y a égalité de répartition des blessures aiguës et chroniques. Pseudomonas aeruginosa est le plus fréquent d'isoler à 30,6%, suivi de Staphylococcus aureus (27,1%), Escherichia coli (9,4%), streptocoques (8,2%), et de Morganella morganii (7,1%). Les isolats présentaient une résistance à l'amoxicilline-clavulanate, ampicilline, cloxacillin, céfuroxime, ceftazidime, faible à modérée de la sensibilité à l'érythromycine, la gentamicine, la streptomycine, la tétracycline, la ciprofloxacine, l'ofloxacine et; et une sensibilité modérée à la ceftriaxone et une forte sensibilité à l'imipénème. Il y avait une différence dans les profils d'antibiorésistance entre les isolats de Gram-positives des infections de plaies aiguës et chroniques mais pas pour les plaies aiguës et chroniques des isolats de bactéries Gram-négatives. Conclusion: La plupart des isolats microbiens, en particulier les bactéries Gram-négatives isolats présentaient une faible sensibilité aux antibiotiques couramment utilisés et l'effet d'une grande sensibilité aux antibiotiques plus récents moins fréquemment utilisés.

INTRODUCTION: Healthcare associated infections (HAI) are the most frequent complication of hospitalized patients. The aim of this study was to describe the clinical and epidemiological characteristics of critically ill post-surgical patients with a diagnosis of healthcare associated infections, after a pattern of sedoanalgesia of at least 4 days. METHODS: All patients over 18 years of age with a unit admission of more than 4 days were consecutively selected. The study population was the one affected by surgical pathology where sedation was based as analgesic the opioid remifentanil for at least 96 hours in continuous perfusion. Patients who died during admission to the unit and those with combined analgesia (peripheral or neuroaxial blocks) were excluded. Data analysis was performed using the statistical package Stata version 7.0. RESULTS: The patients admitted to the Post-Surgical Critical Care Unit (PCU) during study were 1789 and the population eligible was comprised of 102 patients. 56.86% of patients suffered IACS. The most frequent IACS was pneumonia associated with mechanical ventilation (30.96 per 1000 days of mechanical ventilation), Pseudomonas aeruginosa being the most frequently isolated germ. The germs with the greatest involvement in multiple drug resistance (MDROs) were enterobacteria, mainly Klebsiella pneumoniae resistant to extended-spectrum beta-lactamases (ESBL). CONCLUSIONS: Pneumonia associated with mechanical ventilation is the most prevalent HAI and Pseudomonas aeruginosa is the main etiological agent. The groups of antibiotics most frequently used were cephalosporin and aminoglycosides. It is necessary to implement the prevention strategies of the different HAI, since most of them are avoidable.

OBJECTIVES: We aimed to study whether ciprofloxacin prophylaxis reduces infectious complications in patients undergoing autologous haematopoietic cell transplantation (AHCT). METHODS: This is a quasi-experimental, retrospective, before-after study. We compared the incidence of bacterial-related complications among 356 patients with multiple myeloma (MM) (n = 202) and lymphoma (n = 154) who underwent AHCT with (n = 177) or without (n = 179) ciprofloxacin prophylaxis between 03/2007 and 10/2012 and between 10/2012 and 07/2016, respectively, at a single centre. RESULTS: Febrile neutropaenia, bacteraemia, and pneumonia were significantly more common among patients who underwent AHCT during the second study period and did not receive antibacterial prophylaxis compared with patients who underwent AHCT during the first study period and received antibacterial prophylaxis (89.9% (161/179) vs. 83.1% (147/177), difference 6.9%, 95% CI 0-14.1%, P = 0.002; 15.1% (27/179) vs. 4.5% (8/177), difference 10.6%, 95% CI 4.4-16.9%, p < 0.0001; 12.3% (22/179) vs. 6.2% (11/177), difference 6.1%, 95% CI 0-12.3%, p = 0.04, respectively). The number-needed-to-treat to prevent one episode of bacteraemia, pneumonia, and febrile neutropaenia was 8.6, 8.5, and 13.7, respectively. Patients with ciprofloxacin prophylaxis had higher rates of ciprofloxacin-resistant bacteraemia (62.5% (5/8) vs. 18.5% (5/27), difference 44%, 95% CI 7-70%, p = 0.01). In multivariate analysis, ciprofloxacin prophylaxis significantly decreased the odds of bacteraemia (OR 0.19, 95% CI 0.07-0.52; p < 0.0001) and pneumonia (OR 0.37, 95% CI 0.16-0.85, p = 0.02). CONCLUSION: According to our single-centre experience, patients with MM and lymphoma undergoing AHCT may benefit from antibacterial prophylaxis with ciprofloxacin.

BACKGROUND: Intracranial infections, especially multidrug-resistant (MDR) bacterial meningitis, are one of the most severe complications after craniotomy and may greatly impact patient outcomes. CASE PRESENTATION: We report a case of severe MDR Klebsiella pneumonia meningitis after craniotomy that was treated with three different dosages of tigecycline (Pfizer, New York, NY, U.S.A.)via a combined intravenous (IV) and intracerebroventricular (ICV) administration. Here, we discuss the pharmacokinetics (PK) of a combined IV and ICV tigecycline administration for a patient with an intracranial infection after craniotomy. CONCLUSION: In the present case, three different dosages of tigecycline were administered: 49 mg IV plus 1 mg ICV q12 h, 45 mg IV plus 5 mg ICV q12 h, 40 mg IV plus 10 mg ICV q12 h. The combined IV and ICV administration might improve CSF tigecycline concentrations, and in this case, the methods of administration were safe and effective.

INTRODUCTION: To investigate the use of a high-arginine immunonutrient supplement prior to radical cystectomy for bladder cancer. MATERIALS AND METHODS: We recruited 40 patients to consume a total of four high-arginine immunonutrient shakes per day for 5 days prior to radical cystectomy. The primary outcome measures were safety, tolerability and adherence to the supplementation regimen. Ninety-day postoperative outcomes were also compared between supplemented patients and a cohort of 104 prospectively identified non-supplemented radical cystectomy patients. Multivariable logistic regression models were used to compare overall complications, infectious complications, and readmission rates between groups. RESULTS: There were no serious adverse events during supplementation. Four patients (10%) stopped supplementation due to nausea (n = 2) and bloating (n = 2). Thirty-three patients (83%) consumed all prescribed shakes. Immunonutrient supplementation was not significantly associated with overall complications (adjusted odds ratio [OR] 1.08; 95% confidence interval [CI] 0.50-2.33), infectious complications (OR 1.23; 95% CI 0.49-3.07), or readmissions (OR 1.48; 95% CI 0.62-3.51) on multivariable analyses. CONCLUSIONS: Preoperative supplementation with a high-arginine immunonutrient shake was safe and well tolerated prior to radical cystectomy. Contrary to prior reports, immunonutrient supplementation was not associated with lower postoperative infectious complications in this cohort, perhaps owing to the 5 day supplementation period. Further study is needed to identify the optimal immunonutrient supplement regimen for radical cystectomy patients.
