[Rapid diagnosis of bacteremia by genomic identification]. / Diagnostic rapide des bactériémies par identification génomique.

Our objective was to make a focus on the methods for rapid diagnosis of bacteremia by genomic identification. We also aimed to evaluate the interest of using them in the laboratory practice. The different methods currently available have been presented according to their technologic approach. It is also possible to classify these methods according to the data provided, only bacterial and/or resistance gene identification or also bacterial susceptibility to antibiotics. In case of mono-microbial blood cultures, the performances recorded with these methods are very good as compared to the subcultures on agar media. Nevertheless, they are better for identifications (>90%) than for susceptibility to antibiotics (>80%). Numerous studies demonstrated the positive impact of these methods for decreasing the time necessary to the prescription of an appropriate antimicrobial treatment. However, it is noteworthy that an appropriate organization of the laboratory and a strategy of antimicrobial stewardship in the hospital are necessary. Concurrently, the impact on the patient outcome has not been clearly demonstrated. Lastly, few medico-economic studies have been reported. However, as these methods have a substantial cost, their utilization strategy must be economically viable.

Single-dose fosfomycin could prevent infectious complications after retrograde intrarenal surgery: A prospective study.

BACKGROUND: In this study, we aimed to show the protective effect of a single-dose Fosfomycin from infective complications against the standard usage of cephalosporine before retrograde intrarenal surgery. MATERIAL: A total of 186 patients who underwent retrograde intrarenal surgery between 2020 and 2021, included the study. Patients were divided into two groups: group 1(n=49), patients who received an oral dose of 3g Fosfomycin tromethamine powder administered 4-6h before the operation; and group 2 (n=137): patients who received Cephalosporin 30min before surgery and an additional dose 6h after surgery. RESULTS: The median age and stone size were significantly higher in the cephalosporin group (P=0.006 and P=0.008, respectively). There was no statistically significant difference between the groups in terms of postoperative fever and postoperative UTI (P=0.408 and P=0.438). Additionally, no patient developed sepsis. and no adverse event was seen in either group. Preoperative urinary tract infection (UTI) and previous Extracorporeal Shock Wave lithotripsy (ESWL) were independent risk factors and increased postoperative infectious complications (O.R. 2.929 95% C.I. 0.723, P<0.001, and O.R. 2.860 95% C.I. 0.985, P=0.004, respectively). CONCLUSION: Infectious is still one of the important complications after RIRS, and preoperative UTI is an independent risk factors for infections. Fosfomycin monotherapy could be sufficient and is also effective in patients with preoperative culture positive.

Preoperative polymicrobial urine culture: An analysis of the risk of perioperative urinary tract infection.

PURPOSE: To report our management of preoperative polymicrobial urine culture and to determine its correlation with the risk of postoperative urinary tract infection (UTI). PATIENTS AND METHODS: We retrospectively identified all patients with preoperative polymicrobial urine culture in our center between January 2017 and October 2019. Preoperative urine cultures were collected 5 to 8 days before the surgery. No antibiotic prophylaxis was administered preoperatively in the absence of pyuria. Patients with pyuria (≥10 leukocytes/mm3) were treated preoperatively with Ceftriaxone. In case of beta-lactam allergy, the choice between other antibiotic therapies was left to the surgeon's discretion. A second urine culture was collected the day before surgery. The primary endpoint was the occurrence of UTI within 15 days following surgery. RESULTS: In all, 690 patients were included in the study. In line with our protocol, patients had Ceftriaxone, Fluoroquinolones, another antibiotic or no antibiotic prophylaxis in 492 cases (71.3%), 22 cases (3.2%), 31 cases (4.5%), and 145 cases (21%), respectively. The overall sterilization rate of 40.4% was similar between each treatment arm (P=0.54). Postoperative UTI occurred in 68 cases (10.5%). In multivariate analysis, a sterile urine culture the day before surgery was the only factor decreasing the risk of postoperative UTI (OR 0.39, 95%CI, 0.17-0.84; P=0.022). CONCLUSIONS: Our findings suggest that empirical antibiotic therapy for the treatment of preoperative polymicrobial urine culture is no longer adequate. Further evaluation of organisms isolated may provide the necessary antibiograms for initiation of susceptibility based antibiotic therapy that could decrease postoperative UTI rates.

[Guidelines from the cancer (CC-AFU) and infection disease (CI-AFU) committees of the French Association of Urology for the management of adverse events and complications of BCG]. / Recommandations des Comités de cancérologie (CC-AFU) et d'infectiologie (CI-AFU) de l'Association française d'urologie pour la prise en charge effets indésirables et complications du BCG.

INTRODUCTION: Intravesical instillations of BCG are recommended for the treatment of high-risk non-muscle-invasive bladder cancer. However, their prolonged use remains limited by the associated potentially serious adverse effects or complications. The purpose of this article was to provide updated recommendations for the diagnosis and management of adverse events (AEs) or complications of intravesical BCG instillations. MATERIALS AND METHODS: Review of the literature in Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using the following MeSH keywords or a combination of these keywords: "bladder," "BCG," "complication," "toxicity," "adverse events," "prevention," and "treatment". RESULTS: AEs or complications of BCG included genitourinary and systemic symptoms. The most common complications (cystitis, moderate fever) should be treated symptomatically and may require adjustment to allow patients to have the most complete BCG treatment possible. Serious complications are rare but must be identified promptly because of the life-threatening nature of the disease. Their management is based on the combination of anti-tuberculosis treatments, anti-inflammatory drugs and the definitive discontinuation of BCG. CONCLUSION: The management of BCG AEs requires early identification, rational and effective treatment if necessary, and discussion of the continuation of treatment for each situation.

[Evaluation of French practices in 2019 regarding prevention and treatment of urinary tract infections related to ureteral stent]. / Évaluation des pratiques professionnelles françaises par questionnaire en 2019 concernant la prévention et le traitement des infections urinaires sur matériel endo-urétéral.

INTRODUCTION: Urological recommendations never focused on prevention and treatment of urinary tract infections related to endo-ureteral material. METHODS: We conducted an evaluation of French professional practices in May 2019 in the aim of highlighting the important heterogeneity of practices using a Survey Monkey inquiry. RESULTS: One-hundred-and-seventy-five urologists answered the inquiry, as to say 13% of French urologists. Questions regarding the management of pre-surgical polymicrobial urine sample, medical and surgical management of pyelonephritis on endo-ureteral material and regarding the need to diagnose and treat asymptomatic bacteriuria before endo-ureteral stent removal are the main points a majority of French urologists felt uncomfortable with. CONCLUSION: This study evaluated French practices in 2019. The diversity of the answers highlights the need for new recommendations on these subjects of daily practice. Future recommendations should allow their homogenization based on the existing evidence-based data.

[Immunohistochemical diagnosis of colonic spirochetosis with anti-treponema antibody in patients consulting for chronic diarrhea. Results of a prospective study conducted in 137 patients]. / Diagnostic immunohistochimique de la spirochétose colique avec l'anticorps anti-tréponème chez les patients consultant pour une diarrhée chronique. Résultats d'une étude prospective menée chez 137 patients.

AIM: To assess the incidence of colonic spirochetosis, diagnosed by immunohistochemical stain with anti-Treponema pallidum antibody, in a prospective study of colonic biopsies of patients presenting with chronic diarrhea. MATERIAL AND METHODS: From March 2017 to March 2018 the colonic biopsies of patients presenting with chronic diarrhea were stained with Hematoxylin Eosin and anti-Treponema pallidum antibody. The positive cases were also stained with Steiner stain. RESULTS: A total of 137 colonic biopsies were assessed and 3 cases were positive for immunohistochemical stain with anti-Treponema pallidum antibody (2% of the patients). One case was easy to diagnose with HE stain but the 2 other cases were not. The bacteria were stained with Steiner stain, but less easily seen than with the immunohistochemical stain. No patient was treated with antibiotics. DISCUSSION AND CONCLUSION: The colonic spirochetosis can be easily diagnosed by pathologists with immunohistochemical stain with anti-Treponema pallidum antibody. The bacteria are more easily diagnosed with immunohistochemical stain than with HE stain or Steiner stain. However, colonic spirochetosis is rarely diagnosed on colonic biopsies of patients presenting with chronic diarrhea (2% of the patients in our study). Due to the rarity of the entity, and the cost of immunohistochemical stain and the weak benefit for the patient (no patient in our study was treated with antibiotics for colonic spirochetosis) we cannot advise to perform systematic immunohistochemical stain with anti-Treponema pallidum antibody in all the colonic biopsies of patients presenting with chronic diarrhea.

[Bacillus cereus endocarditis and a probable cutaneous gateway]. / Endocardite à Bacillus cereus avec probable porte d'entrée cutanée.

BACKGROUND: Bacillus cereus is a ubiquitous telluric organism. B. cereus endocarditis is a rare condition seen mostly in prosthetic heart valves and among intravenous drug users. We report a new case of a patient without risk factors and with a good clinical outcome not requiring valve replacement. CASE REPORT: In October 2014, a 50-year-old woman was referred to the dermatology department of Lille University Hospital for lower-limb wounds developing 6 months earlier. She presented fever without clinical signs of infection, except for the lower-limbs wounds. Blood cultures revealed the presence of B. cereus. Transesophageal echocardiography was performed and revealed two foci of aortic valve vegetation with a diameter of 5mm. After bacterial sensitivity testing, rifampicin and levofloxacin treatment was given for six weeks, with complete remission. A skin graft was performed and good improvement was seen. DISCUSSION: Nineteen cases of B. cereus endocarditis have been described previously, only one of which was without risk factors. We described a case of complete remission after a 6-week course of antibiotics. Our case demonstrates that BC should not be considered as a blood culture contamination, and that treatment may be complex due to antibiotic resistance.

Validity of urine dipstick test to assess eradication of urinary tract infection in persons with spinal cord injury.

OBJECTIVES: To prospectively study the predictive value (PV) of urine nitrite (NIT) dipstick testing against urine cultures during antibiotic treatment for urinary tract infection (UTI), and other situations, in patients with spinal cord injury (SCI). METHODS: Inpatients with SCI on intermittent catheterisation (IC) or a Foley indwelling catheter (FC) were included. Urine specimens were collected in patients without symptoms (routine), with symptoms of UTI (suspicion), and on day 4 of a 5-day antibiotic treatment (ATB+3). RESULTS: A total of 157 urine samples were collected in 61 patients: 34 were on IC (95 samples) and 27 on FC (62 samples). The prevalence of asymptomatic bacteriuria in the urine cultures was 89% in routine (70 samples). At ATB+3, microbiological cure was found in 27/30 specimens (IC group) and 2/6 (FC group). In the routine condition, the specificity and positive PV of the NIT tests was 1.00 and sensitivity 0.63. The negative PV was low in both groups. In suspicion of UTI, the sensitivity was between 0.69 and 0.55, the positive PV was 1.00 and the negative PV 0.00 for both groups. At ATB+3, the negative PV and sensitivity was 1.00, specificity 0.85 and positive PV 0.43 in the IC group, and in the FC group, specificity was 1.00, negative PV 0.33 and sensitivity 0.00. CONCLUSION: In the SCI population on intermittent or indwelling catheters with high prevalence of bacteriuria, dipstick testing helped assess the eradication of germs during antibiotic treatment, but showed no value in the decision making process for UTI. LEVEL OF EVIDENCE: 3.

[Infections of implantable ports in haematology patients]. / Infections des chambres à cathéter implantables chez les patients atteints d'une hémopathie.

From 2010 to 2015, a study analysed the infections of implantable ports in haematology patients. Communication, collaboration and diligence were some of the main issues raised.

[Short antibiotic therapy in hospitalized pneumonia: A cohort study]. / Antibiothérapie courte au cours de la pneumonie : PNEUMOSHORT.

INTRODUCTION: Pneumonia is one of the most common indications for antibiotic. Shortening the duration of antibiotic therapy should help reduce bacterial resistance. To date, three randomized control trials have shown non-inferiority of short courses of antibiotic therapy (3 days) compared with 7 days in non-severe pneumonia. The aim of this study was to assess this strategy in real life. METHOD: This retrospective observational cohort study included all patients with pneumonia hospitalized in an internal medical ward from 11/01/2022 to 05/31/2023. We implemented the strategy based on early discontinuation of antibiotic therapy in patients with pneumonia who were clinically stable after 3 days of ß-lactam treatment. RESULTS: Among 49 patients included, median age was 72, median antibiotic duration was 4 days (IQR 3-6), and cure rate at D30 was 88 %. At day 30, we observed one death (2 %), four new antibiotic therapy (9 %), and two new hospitalisation (5 %), among five immunosuppressed patients. Among immunosuppressed patients (n=17; 35 %), failure rate was three times higher in case of short antibiotic courses (3/8; 38 %) than long antibiotic courses (1/7; 14 %). CONCLUSION: Strategy based on early discontinuation of antibiotic therapy in immunocompetent patients with pneumonia who were clinically stable after 3 days of ß-lactam treatment is safe, and easy to implement in a medical ward.

[What's news in dermatological therapy?]. / Quoi de neuf en thérapeutique dermatologique?

Innovations in dermatological therapy remain rare. In 2013, increase in the knowledge of mechanism of action and place in the therapeutic strategies concern some recent drugs. For psoriasis treatment, efficacy and safety of anti IL-17 and anti JAK pathway has been demonstrated in randomized studies versus placebo. In other inflammatory diseases, the role of rituximab in auto immune bullous diseases and of omalizumab in chronic urticaria is better known. This year was published the first randomized trial using anti TNF in hidradenitis suppurativa with positive but limited effects. For infectious diseases, the role of prolonged antibiotherapy in the management of recurrent cellulitis is well documented and new antibiotics appears for the treatment of multi resistant bacteria in infection of skin and soft tissues. Finaly, analysis of quality criteria in dermatological trial showed great capability for increase in quality, a strong prerequiste for treating our patient with safety and efficacy.

[Constrictive pericarditis and disseminated nocardiosis]. / Péricardite constrictive et la nocardiose disséminée.

Human nocardiosis usually involves the respiratory tract or the skin but may disseminate to virtually any organ, it occurs in immunocompromised hosts as well as individuals with no apparent predisposition. Involvement of the pericardium is uncommon, having been reported infrequently in the past, but mandates a special management. This report describes the first case in Europe of a patient with chronic constrictive pericarditis from nocardia brasiliens, successfully treated with pericardiectomy and appropriate antibiotic therapy.

Use of antibiotics in pyogenic flexor tenosynovitis.

Pyogenic flexor tenosynovitis is a frequent and serious condition. However, there is no consensus on the use of antibiotics. The objective of our study was to describe the treatment of this condition and to identify the surgical and medical management parameters to propose an effective and consensual postoperative antibiotic therapy protocol. We retrospectively reviewed pyogenic flexor tenosynovitis of the thumb or fingers treated between 01/01/2013 and 01/01/2018 at a teaching hospital. Inclusion criteria were confirmation of the clinical diagnosis intraoperatively and a minimum post-antibiotic follow-up of 6 months. Comorbidities, type of surgery, antibiotic therapy parameters, and treatment outcome were assessed. One hundred and thirteen patients were included. Fifty-four percent had comorbidities. The most frequent germ was staphylococcus, all patients received postoperative antibiotic therapy. Intravenous or intravenous followed by oral administration did not provide any benefit compared to an exclusively oral treatment (p = 0.46). The duration of postoperative antibiotic therapy (less than 7 days, between 7 and 14 days or more than 14 days) did not lead to any difference in healing rate (p = 0.67). However, treating for less than 7 days versus 7-14 days seemed to be associated with a higher risk of failure, although not statistically significant. Oral postoperative antibiotic therapy with amoxicillin + clavulanic acid for 7-14 days appears to be effective, allowing for outpatient management.

[Survey on antibiotic prescription practices for palliative care terminally ill patients of 75 years old and more]. / Enquête de pratique sur les modalités de prescription des antibiotiques en phase terminale de soins palliatifs chez les patients de plus de 75 ans.

Infections commonly occur terminally ill oldest patients in palliative care and questioned about antimicrobial use. The aim of this study was to describe practitioners' habits. METHOD: ancillary study on antibiotic modalities according to the setting of care from a national practices survey based on self administered questionnaire sent by e-mail in 2017. RESULTS: 220 practitioners/327 used antibiotic, 136 worked in hospital department (52 geriatricians), 20 nursing home and 64 general practitioners (GP). GP declared less palliative care patients (6/year). The antibiotic goal was symptomatic relief for 181 (82.3%) without statistically significant difference between groups. GP (25%) were the group that most collected patient opinion for antibiotic prescription. Nursing home (23%) and GP (18%) reported more urinary tract symptoms than others (11.7%) (P=0.003). Geriatricians (59.6%) declared significantly less urinary analysis than GP (90%) (P=0.0009). 212 doctor (96.4%) faced side effect (SI): more allergic reaction and less administration difficulties than the other groups. The stop decision was collegially took (156, 70,9%) significantly more in hospital (121, 89%) than in community (25, 39.1%) (P<0.001). Patient wishes were noted by 30 (46.96%) only GP. CONCLUSION: Even if practice and number of patients follow up differ from each place of care, doctors' intention in antibiotic use respect palliative care goal to relieve discomfort. It is hard to diagnose infection and complementary exam are scarce. A repeated individualized evaluation with patient, his surrounding and his medical referent participation, is mandatory to give a constant adapted level of care in every place of care.

Profile of Antimicrobial Use in the Pediatric Population of a University Hospital Centre, 2015/16 to 2018/19.

BACKGROUND: Antimicrobial stewardship is a standard practice in health facilities to reduce both the misuse of antimicrobials and the risk of resistance. OBJECTIVE: To determine the profile of antimicrobial use in the pediatric population of a university hospital centre from 2015/16 to 2018/19. METHODS: In this retrospective, descriptive, cross-sectional study, the pharmacy information system was used to determine the number of days of therapy (DOTs) and the defined daily dose (DDD) per 1000 patient-days (PDs) for each antimicrobial and for specified care units in each year of the study period. For each measure, the ratio of 2018/19 to 2015/16 values was also calculated (and expressed as a proportion); where the value of this proportion was ≤ 0.8 or ≥ 1.2 (indicating a substantial change over the study period), an explanatory rating was assigned by consensus. RESULTS: Over the study period, 94 antimicrobial agents were available at the study hospital: 70 antibiotics (including antiparasitics and antituberculosis drugs), 14 antivirals, and 10 antifungals. The total number of DOTs per 1000 PDs declined from 904 in 2015/16 to 867 in 2018/19. The 5 most commonly used antimicrobials over the years, expressed as minimum/maximum DOTs per 1000 PDs, were piperacillin-tazobactam (78/105), trimethoprim-sulfamethoxazole (74/84), ampicillin (51/69), vancomycin (53/68), and cefotaxime (55/58). In the same period, the care units with the most antimicrobial use (expressed as minimum/maximum DOTs per 1000 PDs) were hematology-oncology (2529/2723), pediatrics (1006/1408), and pediatric intensive care (1328/1717). CONCLUSIONS: This study showed generally stable consumption of antimicrobials from 2015/16 to 2018/19 in a Canadian mother-and-child university hospital centre. Although consumption was also stable within drug groups (antibiotics, antivirals, and antifungals), there were important changes over time for some individual drugs. Several factors may explain these variations, including disruptions in supply, changes in practice, and changes in the prevalence of infections. Surveillance of antimicrobial use is an essential component of an antimicrobial stewardship program.

CONTEXTE: La gestion des antimicrobiens est une pratique courante dans les centres hospitaliers afin de réduire l'utilisation inappropriée des antimicrobiens et le risque de résistance. OBJECTIF: Décrire l'évolution de l'utilisation des antimicrobiens dans un centre hospitalier universitaire de 2015­16 à 2018­19. MÉTHODES: Dans cette étude rétrospective, descriptive et transversale, les dossiers pharmacologiques ont servi à déterminer le nombre de jours de traitement (NJT) et la dose définie journalière (DDD) par 1000 jours-présence (JP) pour chaque antimicrobien et pour chaque unité de soins par année de l'étude. Pour chaque mesure, on a également comparé le ratio de 2018­19 à celui de 2015­16, qui est exprimé en proportion; lorsque la valeur de cette proportion était ≤ 0,8 ou ≥ 1,2, ce qui indiquait un changement important durant la période de l'étude, une note explicative a été attribuée par consensus. RÉSULTATS: Durant la période à l'étude, 94 antimicrobiens ont été disponibles dans notre centre : 70 antibiotiques (dont les antiparasitaires et les antituberculeux), 14 antiviraux et 10 antifongiques. Le nombre total de NJT par 1000 JP a diminué de 904 en 2015­16 à 867 en 2018­19. Les cinq antimicrobiens utilisés le plus fréquemment et présentés en minimum / maximum de NJT par 1000 JP étaient les suivants : piperacilline-tazobactam (78/105), trimethoprim-sulfamethoxazole (74/84), ampicilline (51/69), vancomycine (53/68) et cefotaxime (55/58). Pendant la même période, les unités de soins qui faisaient la plus grande utilisation d'antimirobiens (exprimée en minimum / maximum de NJT par 1000 JP) étaient hématologie-oncologie (2529/2723), pédiatrie (1006/1408) et soins intensifs pédiatriques (1328/1717). CONCLUSIONS: Cette étude démontre une consommation stable d'antimicrobiens entre 2015­16 et 2018­19 dans un centre hospitalier universitaire mère-enfant canadien. Malgré le fait que la consommation entre les groupes d'antimicrobiens (antibiotiques, antiviraux, antifongiques) était stable, on a constaté d'importantes variations concernant certains médicaments individuels. Plusieurs facteurs peuvent expliquer cette variation, notamment des ruptures d'approvisionnement, des changements de pratique et des changements dans la prévalence d'infections. La surveillance de la consommation des antimicrobiens est une partie essentielle de tout programme d'antibiogouvernance.

[Survey on the use of antibiotics in exotic pets among Swiss veterinarians]. / Umfrage bei Schweizer Tierärzte/-innen über den Einsatz von Antibiotika bei exotischen Heimtieren.

INTRODUCTION: Monitoring programs and guidelines on the use of antibiotics and antibiotic resistance in human and veterinary medicine have been developed worldwide to promote the prudent use of antibiotics in recent years. However, such information on the use of antibiotics in exotic pets is absent. This fact must be taken into account, since the number of exotic pet patients is constantly increasing and the administration of antibiotics is particular challenging due to the diversity of species and the differences in physiology. The present study reports the results of a survey of frequently used antibiotics and the criteria of antibiotic usage in exotic pets (rabbits, rodents, birds and reptiles) among Swiss veterinarians. These data should form the basis for the development of antibiotic usage guidelines in exotic pets. A total of 61 veterinarians returned the questionnaire. The most important decision-making criteria for antibiotic treatment and antibiotic selection were clinical symptoms (55/59, 93% for antibiotic treatment and 40/59, 68% for antibiotic selection), experience (41/59, 69% and 36/59, 61%, respectively) and textbooks (39/59, 66% and 40/59, 68%). The most important decision-making criteria for dosage and duration of therapy were textbooks (59/59, 100%) and experience (31/59, 53%). The use of a microbial culture was used as a decision criterion for both antibiotic treatment and antibiotic selection by 39% of the participants, sensitivity testing was chosen as a decision criterion by 37% for antibiotic treatment and by 46% for antibiotic selection. Fluoroquinolones were used most frequently, 46/56 (82% of the participants) for rabbits, 49/57 (86%) for rodents, 36/37 (97%) for reptiles and 38/46 (83%) for birds. The vast majority of veterinarians (57/58, 98%) would consult a guide for the use of antibiotics. The frequent use of critical antibiotics in exotic pets underscores the need for a guide to the prudent use of antibiotics. The positive influence of such guidelines has already been proven in dogs and cats.

INTRODUCTION: Pour promouvoir une utilisation prudente des antibiotiques, des programmes de surveillance et des lignes directrices sur l'utilisation des antibiotiques et la résistance aux antibiotiques en médecine humaine et vétérinaire ont été élaborés dans le monde entier ces dernières années. Cependant, il n'existe actuellement aucune information de ce type en ce qui concerne les nouveaux animaux de compagnie ainsi que des informations exhaustives sur l'utilisation d'antibiotiques dans la pratique vétérinaire. Ce fait doit être pris en compte, d'autant plus que le nombre d'nouveaux animaux de compagnie est en constante augmentation dans la patientèle et que l'administration d'antibiotiques est un défi particulier en raison de la diversité des espèces et des différences de physiologie. Dans la présente étude, une enquête a été menée pour avoir un aperçu des antibiotiques fréquemment utilisés et de leurs critères d'utilisation chez les nouveaux animaux de compagnie (lapins, rongeurs, oiseaux et reptiles) auprès de vétérinaires suisses. Ces données sont destinées à servir de base à l'élaboration d'un guide sur les antibiotiques pour les animaux exotiques. Au total 61 vétérinaires ont répondu au questionnaire. Les critères de décision les plus importants pour le traitement antibiotique et la sélection d'un antibiotique étaient les symptômes (55/59, 93% pour le traitement antibiotique et 40/59, 68% pour la sélection de l'antibiotique), l'expérience (41/59, 69% et 36/59, 61%, respectivement) et la littérature spécialisée (39/59, 66% et 40/59, 68%). Les critères de décision les plus importants pour e dosage et la durée du traitement étaient la littérature spécialisée (59/59, 100%) et l'expérience (31/59, 53%). L'utilisation d'une culture bactériologique a été donnée par 39% des participants comme critère de décision à la fois pour le traitement antibiotique et le choix de l'antibiotique et un antibiogramme a été choisi par 37% comme critère de décision pour le traitement antibiotique et 46% pour le choix de l'antibiotique. Il a été constaté que les fluoroquinolones sont utilisées le plus fréquemment, chez 46/56 (82% des participants) pour les lapins, 49/57 (86%) pour les rongeurs, 36/37 (97%) pour les reptiles et 38/46 (83%) pour les oiseaux. La grande majorité des vétérinaires (57/58, 98%) a déclaré qu'ils consulteraient un guide pour l'utilisation des antibiotiques. L'utilisation fréquente d'antibiotiques critiques chez les nouveaux animaux de compagnie souligne la nécessité d'un guide sur l'utilisation prudente des antibiotiques. L'influence positive de ces recommandations a déjà été prouvée pour les chiens et les chats.

[Antibiotic strategy in pleural empyema in children: Consensus by the DELPHI method]. / Stratégie antibiotique dans les pleurésies en pédiatrie : consensus par méthode DELPHI.

INTRODUCTION: The evolution of the microbial epidemiology of pleuropulmonary infections complicating community-acquired pneumonia has resulted in a change in empirical or targeted antibiotic therapy in children in the post Prevenar 13 era. The three main pathogens involved in pleural empyema in children are Streptococcus pneumoniae, Staphylococcus aureus and group A Streptococcus. METHODS: A questionnaire according to the DELPHI method was sent to experts in the field (paediatric pulmonologists and infectious disease specialists) in France with the purpose of reaching a consensus on the conservative antibiotic treatment of pleural empyema in children. Two rounds were completed as part of this DELPHI process. RESULTS: Our work has shown that in the absence of clinical signs of severity, the prescription of an intravenous monotherapy is consensual but there is no agreement on the choice of drug to use. A consensus was also reached on treatment adjustment based on the results of blood cultures, the non-systematic use of a combination therapy, the need for continued oral therapy and the lack of impact of pleural drainage on infection control. On the other hand, after the second round of DELPHI, there was no consensus on the duration of intravenous antibiotic therapy and on the treatment of severe pleural empyema, especially when caused by Staphylococci. CONCLUSIONS: The result of this work highlights the needed for new French recommendations based on the evolution of microbial epidemiology in the post PCV13 era.

Assessing the benefit of the 72-hour antibiotic therapy reassessment documentation.

OBJECTIVES: To assess the documentation of the 72-hour antibiotic therapy reassessment in medical records. METHODS: One-day prevalence evaluation of curative antibiotic therapies≥72hours. The documentation of the reassessment was defined according to three criteria: (1) "clear" documentation (clinical or microbiological comment associated with a comment on the need to adjust the antibiotic therapy or on the lack of need); (2) "tacit" documentation (only based on a clinical or microbiological comment); (3) no documentation. RESULTS: We assessed 114 antibiotic therapies in 26 hospital departments. A clear reassessment at 72hours was observed in only 45 (39%) records and 31 (27%) records had no reassessment. The planned duration of treatment was written in 63 (55%) records. At 72hours, among the 71 antibiotic therapies with a microbiological documentation, 69 (97%) were active and 44 (62%) had a narrow spectrum. Among the 48 antibiotic therapies with a broad spectrum on day 1, only 21 (44%) benefited from a de-escalation at 72hours. A clearly recorded reassessment at 72hours was associated with de-escalation (P=0.025) and the prescription of a planned duration of treatment was associated with antibiotic therapy compliance with local or national guidelines (P=0.018). CONCLUSION: Although reassessment was observed in 73% of records, it was correctly recorded at 72hours in only 39% of cases. The documentation of the reassessment and the prescription of a planned duration were associated with a better quality of antibiotic prescription (de-escalation, compliance with guidelines) and are relevant indicators for monitoring the proper use of antibiotics.

[Orbital cellulitis in children: Report of 60 cases]. / Les cellulites orbitaires chez l'enfant : à propos de 60 cas.

The goal of this study was to describe the epidemiological, etiological, clinical and therapeutic features and clinical course of orbital cellulitis in children, and to assess the risk factors for retroseptal involvement. METHODS: This was a retrospective study including 60 children (67 eyes) diagnosed with orbital cellulitis. Two groups were defined according to the clinical form: pre- or retroseptal. RESULTS: We studied 29 cases (34 eyes) of preseptal cellulitis and 31 cases (33 eyes) of retroseptal cellulitis. The mean age was 4 years. The male: female ratio was 1.3. The prescription of anti-inflammatory drugs and antibiotics prior to hospitalization was noted in respectively four and 10 patients. Eyelid edema was the principal sign (100% of cases); exophthalmia was noted in 19 eyes, ptosis in 27 eyes and chemosis in 10 eyes. Oculomotor disorders were present in 4 eyes. The mean C-reactive protein level was 53.15±27mg/l in preseptal cellulitis and 92.09±21mg/l in the retro-septal cases. Orbital computed tomography was performed in 31 patients and MRI in 5 patients. The pathway of entry of the orbital infection was primarily from the sinuses (23 cases). All of our patients had received broad spectrum intravenous antibiotic therapy. Three children had a cavernous sinus thrombosis and had been treated with anticoagulant therapy. Surgical drainage was performed in five patients. The course was favorable and without sequelae for all the patients. Two independent risk factors for retroseptal involvement were identified: the prescription of anti-inflammatory drugs prior to hospitalization, and sinus involvement. CONCLUSION: Orbital cellulitis in children is a serious infection and requires close collaboration between the ophthalmologist, otolaryngologist, and pediatrician in order to be diagnosed and treated early so as to improve the prognosis for vision and life.

This review of the treatment of uncomplicated pelvic inflammatory disease (PID) focuses on the susceptibility profile of the main microbiological causes as well as on the advantages and inconvenients of relevant antibiotics. As bacterial resistance is expanding in the community, the rules of adequate antibiotic prescribing are integrated in the treatment proposals. While the pathogenic role of anaerobic bacteria in uncomplicated PID remains discussed, the choice to provide anaerobes coverage is proposed. Thus, the antibiotic treatment has to cover Chamydia trachomatis, Neisseria gonorrhoeae, anaerobes as well as Streptococcus spp, gram negative bacteria and the ermerging Mycoplasma genitalium. On the basis of published trials and good practice antibiotic usage, the ceftriaxone-doxycycline-metronidazole combination has been selected as the first line regimen. Fluoroquinolones (moxifloxacin alone, or levofloxacin or ofloxacin combined with metronidazole) are proposed as alternatives because of their ecological impact and their side effects leading to restricted usage. When fluoroquinolone are used, ceftriaxone should be added in case of possible sexually transmitted infection. When detected, M. genitalium should be treated by moxifloxacin. Moreover, this review highlights the need to better describe the microbiological epidemiology of uncomplicated PID in France or Europe.
