RESUMO
BACKGROUND: The optimal duration of intravenous antibiotic therapy in Staphylococcus aureus prosthetic bone and joint infection has not been established. The objective of this study was to compare the effect of early and late intravenous-to-oral antibiotic switch on treatment failure. PATIENTS AND METHODS: We retrospectively analyzed all adult cases of S. aureus prosthetic bone and joint or orthopedic metalware-associated infection between January 2008 and December 2015 in a French university hospital. The primary outcome was treatment failure defined as the recurrence of S. aureus prosthetic bone and joint or orthopedic metalware-associated infection at any time during or after the first line of medical and surgical treatment within 2 years of follow-up. A Cox model was created to assess risk factors for treatment failure. RESULTS: Among the 140 patients included, mean age was 60.4 years (SD 20.2), and 66% were male (n = 92). Most infections were due to methicillin-susceptible S. aureus (n = 113, 81%). The mean duration of intravenous antibiotic treatment was 4.1 days (SD 4.6). The majority of patients (119, 85%) had ≤5 days of intravenous therapy. Twelve patients (8.5%) experienced treatment failure. Methicillin-resistant S. aureus infections (HR 11.1; 95% CI 1.5-111.1; p = 0.02), obesity (BMI > 30 kg/m2) (HR 6.9; 95% CI1.4-34.4, p = 0.02) and non-conventional empiric antibiotic therapy (HR 7.1; 95% CI 1.8-25.2; p = 0.005) were significantly associated with treatment failure, whereas duration of intravenous antibiotic therapy (≤ 5 or > 5 days) was not. CONCLUSION: There was a low treatment failure rate in patients with S. aureus prosthetic bone and joint or orthopedic metalware-associated infection with early oral switch from intravenous to oral antibiotic therapy.

Few point prevalence surveys (PPS) have been conducted in Vietnam on Surgical Site Infections (SSI) or antimicrobial use in surgery. The objective of this study was to evaluate the PPSs of SSI before and after implementation of antibiotic stewardship programs (ASP) and infection control (IC) in a Vietnamese tertiary care hospital. ASP and IC practices were implemented in operating rooms and the orthopedic department, including antibiotic training, skin preparation, hand hygiene, gloves and sterile instruments, and SSIs risk factors. A PPS of SSIs and antimicrobial use was performed in January 2016 according to methods from the Centers for Disease Control and Prevention, before ASP and IC, and in December 2019. Information recorded included surgical data, antibiotic prophylaxis, microorganisms, and SSI risk factors. Skin preparation compliance assessed preoperative washing and antisepsis. SSI prevalence was 7.8% in 2016 versus 5.4% in 2019 (p = 0.7). The use of prophylactic antibiotics decreased from 2016 to 2019. A third-generation cephalosporin was prescribed more than 48 h after surgery for most patients. Skin preparation compliance increased from 54.4% to 70.5% between assessments. The decreased SSI, although non-statistically significant, warrants continuing this program. Vietnamese hospitals must provide comprehensive IC education to healthcare workers to address the prevention of SSI and establish IC policies.
RESUMO
BACKGROUND: Inhalation of hydrogen cyanide from smoke in structural fires is common, but cardiovascular function in these patients is poorly documented. OBJECTIVE: The objective was to study the cardiac complications of cyanide poisoning in patients who received early administration of a cyanide antidote, hydroxocobalamin (Cyanokit; Merck KGaA, Darmstadt, Germany [in the United States, marketed by Meridian Medical Technologies, Bristol, TN]). METHODS: The medical records of 161 fire survivors with suspected or confirmed cyanide poisoning were reviewed in an open, multicenter, retrospective review of cases from the Emergency Medical Assistance Unit (Service d'Aide Médical d'Urgence) in France. RESULTS: Cardiac arrest (61/161, 58 asystole, 3 ventricular fibrillation), cardiac rhythm disorders (57/161, 56 supraventricular tachycardia), repolarization disorders (12/161), and intracardiac conduction disorders (5/161) were observed. Of the total 161 patients studied, 26 displayed no cardiac disorder. All patients were given an initial dose of 5 g of hydroxocobalamin. Non-responders received a second dose of 5 g of hydroxocobalamin. Of the patients initially in cardiac arrest, 30 died at the scene, 24 died in hospital, and 5 survived without cardiovascular sequelae. Cardiac disorders improved with increasing doses of hydroxocobalamin, and higher doses of the antidote seem to be associated with a superior outcome in patients with initial cardiac arrest. CONCLUSIONS: Cardiac complications are common in cyanide poisoning in fire survivors.

For the last ten years, non-Aspergillus mold species have been increasingly involved in human invasive infections, probably as a consequence of more intense immunosuppression and prolonged patient survival, and of selective pressure since antifungal agents are currently used for prophylaxis or therapy. Scedosporium prolificans, one of these emerging fungi, has been isolated in a broad spectrum of clinical presentations in humans, including respiratory-tract colonization, superficial or locally invasive infections, and disseminated infections in immunocompromised patients. Here, we report the recent emergence of invasive infections due to S. prolificans in France, and describe four new cases diagnosed during the last six years. Only one disseminated scedosporiosis has been reported before this in France, in 1994. Three out of our four cases were breakthrough infections in immunocompromised patients receiving posaconazole or voriconazole therapy. The aims of the present review were thus to gain a better understanding of scedosporiosis epidemiology and clinical features, and to review recent advances in multimodal management of these infections, including surgery, recovery and/or enhancement of immunity, and antifungal combinations, especially voriconazole plus terbinafine.

OBJECTIVE: Candiduria is a common finding in the growing population of very old patients that has not been previously studied. The objective was to study candiduria in the population aged 85 and over, including an estimation of the incidence, factor of acquisition, and evaluation of treatment and mortality. METHODS: Retrospective monocentric study. Materials medical charts of patients aged of 85 and over who have candiduria diagnosed at Nimes University Hospital. RESULTS: The prevalence of candiduria in the hospitalized very old patients was 8.9%. More than half of strains isolated were C. albicans (59%). Mean age was 89.7 years old with 53 women and 20 men. Urinary catheter (55%) and prior antibiotic use (67%) were commonly found. Fifteen patients with candiduria were treated, consistently with fluconazole. Patients treated had higher Mini Mental Test score than the others. A high C-reactive protein level, Mac Cabe score or Charlson's score >7 were associated with 6 months mortality. CONCLUSION: Episodes of candiduria in oldest old were associated with frailty and vulnerability of the patient. The medical decision for antifungal treatment is usually difficult to make but it did not seem to influence mortality.
