Long survival of patients with metastatic clear cell renal cell carcinoma. Results of real life study of 344 patients.

The treatment landscape in metastatic renal cell carcinoma has changed fundamentally over the last decade by the development of antiangiogenic agents, mammalian target of rapamycin inhibitors and immunotherapy. Outside of the context of a clinical trial, the treatments are used sequentially. We describe results under real-life conditions of a sequential treatment strategy, before the era of immunotherapy. All patients were treated according to their prognostic score (either Memorial Sloan Kettering Cancer Center or International Metastatic Renal Cell Carcinoma Database Consortium) for advanced renal cell carcinoma. A treatment strategy involving 1 to 4 lines was determined including a rechallenge criterion for the repeat use of a treatment class. Three hundred forty-four patients were included over 3 years. Overall survival was 57 months in patients with good or intermediate prognosis and 19 months in patients with poor prognosis. In the former group, the proportions of patients treated with 2 to 4 treatment lines were 70%, 38% and 16%, respectively. The best objective response rates for lines 1 to 4 were 46%, 36%, 16% and 17%, respectively. Grade III/IV toxicity did not appear to be cumulative. The recommended strategy was followed in 68% of patients. A large proportion of patients with good or intermediate prognosis who progress after two lines of treatment still have a performance status good enough to receive a systemic treatment, which justifies such a strategy. Overall survival of patients with good and intermediate prognosis was long, suggesting a benefit from the applied approach. These results might be used as selection criterion for the treatment of patients in the era of immune checkpoint inhibitors.

Severe alcohol hand rub overdose inducing coma, watch after H1N1 pandemic.

BACKGROUND: Alcoholic hand rubs (AHRs) have been proven effective in preventing nosocomial infections, and healthcare authorities include AHRs use among quality-of-care criteria. Since the onset of the influenza A (H1N1) pandemic, AHRs have gained considerable popularity among the general public. METHODS: We report a case of intentional AHRs self-poisoning inducing rapid coma with hyperlactatemia, and a full recovery. The relevant literature was reviewed. To our knowledge, this is the third reported case of intentional AHRs poisoning. 3 patients presented with a picture of acute alcohol intoxication, of variable severity depending on the amount ingested and speed of ingestion. RESULTS: The blood alcohol level was 414 mg/dl and tests for other drugs were performed 30 min after admission. The blood lactate level increased briefly to 4.8 mmol/l, without renal or hepatic function disturbances. She regained consciousness after 6 h then achieved a full recovery allowing extubation and readmission to the psychiatric ward after 24 h. She reported gulping down the entire contents of the Aniosgel bottle. CONCLUSION: Whereas overdrinking in social settings (wine and liquor) leads to a gradual increase in blood alcohol levels, AHRs poisoning is usually characterized by a sudden massive alcohol load. The unusual nature of the alcohol source may lead to diagnostic wanderings. AHRs are currently available in bottles that facilitate the ingestion of large amounts. Unit-dose packaging or dispensing might decrease the risk of AHRs poisoning.

Surgical site infection after surgery to repair femoral neck fracture: a French multicenter retrospective study.

OBJECTIVE: Femoral neck fracture is the most frequent orthopedic emergency among elderly persons. Despite a high prevalence of methicillin-resistant Staphylococcus aureus (MRSA) carriage in this population, no multicenter study of antibiotic prophylaxis practices and the rate and microbiological characteristics of surgical site infection (SSI) has been performed in France. DESIGN: Retrospective, multicenter cohort study. SETTING: Twenty-two university and community hospitals in France. PATIENTS: Each center provided data on 25 consecutive patients who underwent surgery for femoral neck fracture during the first quarter of 2005. Demographic, clinical, and follow-up characteristics were recorded, and most patients had a follow-up office visit or were involved in a telephone survey 1 year after surgery. RESULTS: These 22 centers provided data on 541 patients, 396 (73%) of whom were followed up 1 year after surgery. Of 504 (93%) patients for whom antibiotic prophylaxis was recorded, 433 (86%) received a cephalosporin. Twenty-two patients had an SSI, for a rate of 5.6% (95% confidence interval, 3.7-8.0). SSI was reported for 15 (6.9%) of patients who had a prosthesis placed and for 7 (3.9%) who underwent osteosynthesis (P=.27). SSI was diagnosed a median of 30 days after surgery (interquartile range, 21-41 days); 7 (32%) of these SSIs were superficial infections, and 15 (68%) were deep or organ-space infections. MRSA caused 7 SSIs (32%), Pseudomonas aeruginosa caused 5 (23%), other staphylococci caused 4 (18%), and other bacteria caused 2 (9%); the etiologic pathogen was unknown in 4 cases (18%). Reoperation was performed for 14 patients with deep or organ-space SSI, including 6 of 7 patients with MRSA SSI. The mortality rate 1 year after surgery was 20% overall but 50% among patients with SSI. In univariate analysis, only the National Nosocomial Infections Surveillance System risk index score was significantly associated with SSI (P=.006). CONCLUSIONS: SSI after surgery for femoral neck fracture is severe, and MRSA is the most frequently encountered etiologic pathogen. A large, multicenter prospective trial is necessary to determine whether the use of antibiotic prophylaxis effective against MRSA would decrease the SSI rate in this population.

Comparison of routine prophylaxis with vancomycin or cefazolin for femoral neck fracture surgery: microbiological and clinical outcomes.

OBJECTIVE: To assess the impact of antibiotic prophylaxis on the emergence of vancomycin-resistant strains of Enterococcus faecium, Enterococcus faecalis, and Staphylococcus aureus and the incidence of surgical site infection (SSI) after vancomycin or cefazolin prophylaxis for femoral neck fracture surgery. DESIGN: Prospective cohort study. SETTING: A hospital with a high prevalence of methicillin-resistant S. aureus (MRSA) carriage. PATIENTS: All patients admitted with a femoral neck fracture from March 1, 2004 through February 28, 2005 were prospectively identified and screened for MRSA and vancomycin-resistant (VRE) carriage at admission and at day 7. Deep incisional and organ/space SSIs were also recorded. RESULTS: Of 263 patients included in the study, 152 (58%) received cefazolin and 106 (40%) received vancomycin. At admission, the prevalence of MRSA carriage was 6.8%; it was 12% among patients with risk factors and 2.2% among patients with no risk factors (P=.002). At day 7 after surgery, there were 6 patients (2%) who had hospital-acquired MRSA, corresponding to 0.7% in the cefazolin group and 5% in the vancomycin group (P=.04); none of the MRSA isolates were resistant to glycopeptides. The rate of VRE carriage at admission was 0.4%. Three patients (1%) had acquired carriage of VRE (1 had E. faecium and 2 had E. faecalis); all 3 were in the cefazolin group (2% of patients) and none in the vancomycin group (P=.27). Eight SSIs (3%) occurred, 4% in the cefazolin group and 2% in the vancomycin group (P=.47). CONCLUSIONS: This preliminary study demonstrates that cefazolin and vancomycin prophylaxis have similar impacts on the emergence of glycopeptide-resistant pathogens. Neither MRSA infection nor increased rates of SSI with other bacteria were observed in the vancomycin group, suggesting that a larger multicenter study should be initiated.

The Plasmair Decontamination System Is Protective Against Invasive Aspergillosis in Neutropenic Patients.

OBJECTIVE Invasive aspergillosis (IA) is a rare but severe infection caused by Aspergillus spp. that often develops in immunocompromised patients. Lethality remains high in this population. Therefore, preventive strategies are of key importance. The impact of a mobile air decontamination system (Plasmair, AirInSpace, Montigny-le-Bretonneux, France) on the incidence of IA in neutropenic patients was evaluated in this study. DESIGN Retrospective cohort study METHODS Patients with chemotherapy-induced neutropenia lasting 7 days or more were included over a 2-year period. Cases of IA were confirmed using the revised European Organization for Research and Treatment of Cancer (EORTC) criteria. We took advantage of a partial installation of Plasmair systems in the hematology intensive care unit during this period to compare patients treated in Plasmair-equipped versus non-equipped rooms. Patients were assigned to Plasmair-equipped or non-equipped rooms depending only on bed availability. Differences in IA incidence in both groups were compared using Fisher's exact test, and a multivariate analysis was performed to take into account potential confounding factors. RESULTS Data from 156 evaluable patients were available. Both groups were homogenous in terms of age, gender, hematological diagnosis, duration of neutropenia, and prophylaxis. A total of 11 cases of probable IA were diagnosed: 10 in patients in non-equipped rooms and only 1 patient in a Plasmair-equipped room. The odds of developing IA were much lower for patients hospitalized in Plasmair-equipped rooms than for patients in non-equipped rooms (P=.02; odds ratio [OR] =0.11; 95% confidence interval [CI], 0.00-0.84). CONCLUSION In this study, Plasmair demonstrated a major impact in reducing the incidence of IA in neutropenic patients with hematologic malignancies. Infect Control Hosp Epidemiol 2016;37:845-851.

Should electronic faucets be used in intensive care and hematology units?

OBJECTIVE: To compare bacterial contamination associated with electronic faucets and manual faucets in wards admitting patients highly susceptible to infection. DESIGN: Water samples from electronic faucets and manual faucets were taken according to the French recommendations on water surveillance in healthcare settings. SETTING: Hematology and intensive care units (ICUs) of a 900-bed university hospital and a 500-bed general hospital. MEASUREMENTS AND RESULTS: Overall 227 water samples were collected, 92 from electronic faucets and 135 from manual faucets. Thirty-six (39%) of the water samples from electronic faucets and 2 (1%) from manual faucets yielded pathogenic bacteria. In hematology wards 17 (30%) samples from electronic faucets and 2 (2%) from manual faucets were contaminated. In ICUs 19 (53%) samples from electronic faucets and none of 48 from manual faucets were contaminated. All samples were contaminated with various strains of Pseudomonas aeruginosa (8 to >100 CFU/100 ml). Despite hyperchlorination the electronic faucets remained contaminated. Replacing the contaminated electronic faucets by manual faucets led to a complete and sustained elimination of bacterial contamination. Contamination was not associated with a particular brand of electronic faucets. CONCLUSIONS: Our findings demonstrate that electronic faucets are significantly more frequently contaminated than manual faucets and could be a major reservoir for P. aeruginosa. Wards admitting patients highly susceptible to infection and using electronic faucets should be aware of this potential threat. Moreover, units already equipped with these devices, should check water quality periodically.

Prevalence of methicillin-resistant Staphylococcus aureus nasal carriage among patients with femoral neck fractures: implication for antibiotic prophylaxis.

Fifteen (8.4%) of 179 patients admitted with femoral neck fractures carried MRSA. Among 96 patients admitted from their homes, only 2 (2%) were carriers, whereas 13 (15.6%) of 83 patients from nursing or residential homes or long-term-care facilities were colonized (P = .001). Routine prophylaxis with vancomycin is recommended in the latter group.
