Abstract
OBJECTIVES To compare the 2 long-term medical strategies in chronic rhinosinusitis without nasal polyps (CRSnNP) and to identify the role of gastroesophageal reflux disease (GERD) and Helicobacter pylori as factors of treatment failure. MATERIAL AND METHODS Fifty-seven patients with CRSnNP were randomized into 2 therapeutic groups. The first group was treated with 4 weeks of amoxicillin/clavulanate and a short course of oral steroids. The second group received 8 weeks of clarithromycin. Sinonasal Outcome Test-20 (SNOT-20) and Lund and Mackay scores were assessed at baseline and after treatment, and GERD Health-Related Quality of Life (GERD-HRQL) questionnaire was evaluated in all patients. Patients with a GERD-HRQL score >8 received esogastroscopy and H pylori detection. Patients were followed during a 10-year period for clinical course and GERD evolution. The 10-year evolution of patients was described in terms of recurrence, medical, and surgical treatments. RESULTS Thirty-seven patients completed the study; SNOT-20 and Lund and Mackay scores similarly improved in both groups. Amoxicillin/clavulanate group had significantly more adverse reactions than the clarithromycin group (P = .03). After the therapeutic course, 35% (amoxicillin/clavulanate) and 41% (clarithromycin) of patients needed functional endoscopic sinus surgery (FESS). During the long-term follow-up, 54% (amoxicillin/clavulanate) and 40% (clarithromycin) of patients had late CRSnNP recurrence; FESS was performed in less than 15% of cases of recurrence. Gastroesophageal reflux disease complaint's severity was associated with late recurrence of CRSnNP. CONCLUSION Amoxicillin/clavulanate and clarithromycin would be competitive treatments for CRSnNP. Gastroesophageal reflux disease seems to be a negative factor for treatment response and recurrence.

Abstract
BACKGROUND Postoperative infection after hand-assisted laparoscopic donor nephrectomy (HALDN) confers significant morbidity to a healthy patient group. Current UK guidelines cite a lack of evidence for routine antibiotic prophylaxis. This trial assessed if a single preoperative antibiotic dose could reduce post HALDN infections. METHODS Eligible donors were randomly and blindly allocated to preoperative single-dose intravenous co-amoxiclav or saline. The primary composite endpoint was clinical evidence of any postoperative infection at 30 days, including surgical site infection (SSI), urinary tract infection (UTI), and lower respiratory tract infection (LRTI). FINDINGS In all, 293 participants underwent HALDN (148 antibiotic arm and 145 placebo arm). Among them, 99% (291/293) completed follow-up. The total infection rate was 40.7% (59/145) in the placebo group and 23% (34 of 148) in the antibiotic group (P = 0.001). Superficial SSIs were 20.7% (30/145 patients) in the placebo group versus 10.1% (15/148 patients) in the antibiotic group (P = 0.012). LRTIs were 9% (13/145) in the placebo group and 3.4% (5/148) in the antibiotic group (P = 0.046). UTIs were 4.1% (6/145) in the placebo group and 3.4% (5/148) in the antibiotic group (P = 0.72).Antibiotic prophylaxis conferred a 17.7% (95% confidence interval 7.2%-28.1%), absolute risk reduction in developing postoperative infection, with 6 donors requiring treatment to prevent 1 infection. INTERPRETATION Single-dose preoperative antibiotic prophylaxis dramatically reduces post-HALDN infection rates, mainly impacting SSIs and LRTIs.

Abstract
STUDY OBJECTIVE Efforts to reduce unnecessary and unnecessarily long antibiotic treatment for community-acquired pneumonia have been attempted through use of procalcitonin and through guidelines based on serial clinical assessment. Our aim is to compare guideline-based clinical assessment- and procalcitonin algorithm-guided antibiotic use among patients with community-acquired pneumonia. METHODS We performed a pragmatic, randomized, multicenter trial from November 2012 to April 2015 at 12 French hospitals. We included emergency department (ED) patients older than 18 years with community-acquired pneumonia. Patients were randomly assigned to either the procalcitonin-guided or clinical assessment group. In accordance with past studies, we hypothesized that serial clinical assessment would be superior to procalcitonin-guided care. The primary outcome was antibiotic duration, and secondary outcomes included rates of antibiotic duration less than or equal to 5 days, and clinical success and combined serious adverse outcomes at 30 days in the intention-to-treat population. RESULTS Of 370 eligible patients, 285 (77%) were randomly assigned to either clinical assessment- (n=143) or procalcitonin-guided care (n=142). Median age was 67 years (range 18 to 93 years) and 40% of patients were deemed to have Pneumonia Severity Index class IV or V. Procalcitonin algorithm adherence was 76%. Antibiotic duration was not significantly different between clinical assessment- and procalcitonin-guided groups (median 9 versus 10 days, respectively). Clinical success rate was 92% in each group and serious adverse outcome rates were similar (15% versus 20%, respectively). CONCLUSION Guideline-based serial clinical assessment did not reduce antibiotic exposure compared with procalcitonin-guided care among ED patients with community-acquired pneumonia. The strategies were similar in terms of duration of antibiotic use and clinical outcomes.

Abstract
BACKGROUND Platinum-based chemoradiotherapy for locally advanced head and neck cancer (LAHNC) induces a high rate of acute toxicity, including dysphagia and aspiration pneumonia. We hypothesised that prophylactic antibiotics can prevent pneumonia and hospitalisations and can be cost-effective. PATIENT AND METHODS In this multicentre randomised trial, patients with LAHNC treated with chemoradiotherapy received prophylactic amoxicillin/clavulanic acid from day 29 after the start of treatment until 14 days after completion of chemoradiotherapy or standard care without prophylaxis. The primary objective was to observe a reduction in pneumonias. Secondary objectives were to evaluate the hospitalisation rate, adverse events, costs and health-related quality of life. RESULTS One hundred six patients were included; of which, 95 were randomised: 48 patients were allocated to the standard group and 47 patients to the prophylaxis group. A pneumonia during chemoradiotherapy and follow-up until 3.5 months was observed in 22 (45.8%) of 48 patients in the standard group and in 22 (46.8%) of 47 patients in the prophylaxis group (p = 0.54). Hospitalisation rate was significantly higher in the standard group versus the prophylaxis group, 19 of 48 pts (39.6%) versus 9 of 47 pts (19.1%), respectively (p = 0.03). Significantly more episodes with fever of any grade were observed in the standard group (29.2% vs 10.2%, p = 0.028). A significant difference in costs was found, with an average reduction of €1425 per patient in favour of the prophylaxis group. CONCLUSION Although prophylactic antibiotics during chemoradiotherapy for patients with LAHNC did not reduce the incidence of pneumonias, it did reduce hospitalisation rates and episodes with fever significantly and consequently tended to be cost-effective.

Effect of Antimicrobial Treatment on the Resolution of Middle-Ear Effusion After Acute Otitis Media.
Ruohola, A, Laine, MK, Tähtinen, PA
Journal of the Pediatric Infectious Diseases Society. 2018;(1):64-70
Abstract
BACKGROUND Acute otitis media (AOM) induces middle-ear effusion (MEE), which affects hearing. The effect of antimicrobial treatment on the resolution of MEE is controversial, and the factors that affect resolution are unknown. METHODS We studied the effect of antimicrobial treatment on the time to the resolution of MEE as a secondary objective in our randomized double-blind placebo-controlled trial. Children aged 6 to 35 months with stringently diagnosed AOM were allocated to receive amoxicillin-clavulanate (161 patients) or placebo (158 patients) for 7 days and closely followed for 3 months. This study was registered at ClinicalTrials.gov (identifier NCT00299455). RESULTS The median times to resolution of MEE were 20 days (95% confidence interval [CI], 16-24 days) and 29 days (95% CI, 26-32 days) in the amoxicillin-clavulanate and placebo groups, respectively (P = .10). The resolution of MEE was confirmed in 138 (86%) of 161 and 132 (84%) of 158 patients in the amoxicillin-clavulanate and placebo groups, respectively (P = .59). In multivariable analysis, the resolution of MEE was prolonged most significantly by at least 1 recurrence of AOM during follow-up. MEE resolved in 65 (65%) of 100 patients with a recurrence of AOM during follow-up and in 205 (94%) of 219 of those without a recurrence (P < .001) (median times to resolution, 67 vs 15 days, respectively; P < .001). CONCLUSIONS Immediate antimicrobial treatment of AOM does not significantly affect the resolution of MEE in young children. Subsequent recurrences of AOM are a major reason for the persistence of MEE.

The British journal of nutrition. 2016;(1):94-103
Abstract
Broad-spectrum antibiotic use can disrupt the gastrointestinal microbiota resulting in diarrhoea. Probiotics may be beneficial in managing this type of diarrhoea. The aim of this 10-week randomised, double-blind, placebo-controlled, parallel study was to investigate the effect of Lactobacillus helveticus R0052 and Lactobacillus rhamnosus R0011 supplementation on antibiotic-associated diarrhoea in healthy adults. Subjects were randomised to receive 1 week of amoxicillin-clavulanic acid (875 mg/125 mg) once per day, plus a daily dose of 8×109 colony-forming units of a multi-strain probiotic (n 80) or placebo (n 80). The probiotic or placebo intervention was maintained for 1 week after completion of the antibiotic. Primary study outcomes of consistency and frequency of bowel movements were not significantly different between the probiotic and placebo groups. The secondary outcomes of diarrhoea-like defecations, Gastrointestinal Symptoms Rating Scale scores, safety parameters and adverse events were not significantly different between the probiotic intervention and the placebo. A post hoc analysis on the duration of diarrhoea-like defecations showed that probiotic intervention reduced the length of these events by 1 full day (probiotic, 2·70 (sem 0·36) d; placebo, 3·71 (sem 0·36) d; P=0·037; effect size=0·52). In conclusion, this study provides novel evidence that L. helveticus R0052 and L. rhamnosus R0011 supplementation significantly reduced the duration of diarrhoea-like defecations in healthy adults receiving antibiotics.

Khirurgiia. 2016;(6):68-76
Abstract
AIM: To assess an incidence rate of surgical site infections (SSI) after open appendectomy and effectiveness of combined preventive measures (CPM). MATERIAL AND METHODS This study was performed at three surgical departments of Smolensk hospitals. A total of 150 consecutive patients (50 at each department) hospitalized since January 2012 were included into the retrospective observation (period I). In order to perform prospective evaluation of CPM, a total of 66 consecutive patients (randomized 1:1) hospitalized since December 2012 (period II) were followed up at each of the departments. Antibiotic prophylaxis (AP) with IV amoxicillin/clavulanate (1.2 g) was planned for all patients from period II. The study group (group 1) included patients with surgical wound closure with triclosan-coated polyglactin 910 and additionally with a skin 2-octylcyanoacrylate-based adhesive. The control group (group 2) included patients with surgical wound closure with non-triclosan-coated polyglactin 910. Each patient from the period II was assigned to an "Individual SSI Prevention Package" (IPP), which included an antibiotic, sutures, skin adhesive (only in a package for CPM) and label "AP" for patients' medical records. Patients' medical records were reviewed by one expert. Exclusion criteria were: age <14 years; transition to midline laparotomy; drainage of the abdominal cavity through the surgical wound; simultaneous interventions; secondary appendicitis; refusal to use of sutures from the IPP. In order to determine signs of SSI presence/absence within 30 days after surgery, attempts to contact with patients by phone were made. The data obtained was recorded into case report forms and then entered into the study database. RESULTS A total of 322 patients were included into the final analysis (mean age: 34.8±17.1 years). The mean length of hospital stay was 8.2±2.5 days. The mean duration of hospital stay with or without SSI was 7.9±1.8 and 14.2±4.0 days, respectively (p<0.001). The AP during the periods I and II was performed in 56.1% (83/148) and 97.7% (170/174) of patients, respectively (p<0.00001). Cephalosporins I-IV were the most frequently used antibiotics during the period I (85.6%). During the period II, amoxicillin/clavulanate from IPP was used in 98.2% of patients. Percentage of IV antibiotic administration in different time periods was 57.3% and 98.2%, respectively (p<0.0001); frequency of the first administration before skin incision was 53.6% and 97.1%, respectively (p<0.0001). The telephone contact with patient was successful in 74.8% (both periods), 56.8% (period I) and 90.2% (period II) of cases, respectively. SSI was recorded only once per patient with the following priority: SSI was documented in the patient's medical record; patient developed SSI that was not documented (in the expert's opinion) in the patient's medical record; SSI signs were determined during the telephone contact or reported by the patient. The incidence of SSI in both study periods, period I and period II was 14.9%, 15.5% and 14.4%, respectively (p>0.05 for all comparisons). In the patient subgroup with successful telephone contact, the incidence of SSI in both study periods, period I and period II was 17.4%, 21.4% and 15.3%, respectively; the incidence of SSI in group 1 and group 2 of the period II was 12.0% and 18.9%, respectively (p>0.05 for all comparisons). CONCLUSION SSI after an open appendectomy remains an important problem. In order to determine a true incidence of SSI, it is necessary to improve the national nosocomial infection surveillance system. The CMP used in the study have showed a trend to significant SSI risk reduction and may be recommended to maximize patient protection. Further large studies are needed to confirm effectiveness of the proposed CMP.

Prophylactic antibiotic therapy for fractures of the maxillary sinus.
Schmidt, RS, Dodson, KM, Goldman, RA
Ear, nose, & throat journal. 2015;(4-5):170-7
Abstract
We conducted a study to examine the incidence of acute sinusitis following maxillary sinus fractures, as well as the impact of antibiotics in the postinjury period. Fifty patients who presented to our institution with a fracture of the maxillary sinus were prospectively randomized to receive either a nasal saline spray and a 3-day course of antibiotics (either amoxicillin/clavulanate or levofloxacin) or nasal saline alone; there were 25 patients in each group. After a minimum of 3 days, all patients were assessed for acute sinusitis. Follow-up data were available on 17 patients (a total of 21 fractured sinuses) in the antibiotic group (68%) and 14 patients (17 fractured sinuses) in the control group (56%). The groups were balanced in terms of demographics, location of fractures, mechanism of fracture, and time to follow-up. After 3 days, 95.23% of the fractured sinuses in the antibiotic group and 88.23% of the fractured sinuses in the control group exhibited signs or symptoms consistent with or suggestive of acute sinusitis. Very few sinuses in either group showed no evidence of sinusitis: only 1 in the antibiotic group (4.76%) and 2 in the control group (11.76%); this difference was not significant (p = 0.5768). We conclude that while the clinical rate of acute sinusitis after maxillary sinus fractures is high, a 3-day course of antibiotics is not effective in preventing its symptoms in the postinjury period.
