Efficacy of vancomycin lock therapy for totally implantable venous access port-related infection due to coagulase-negative staphylococci in 100 patients with cancer. J Antimicrob Chemother 2023; 78:1253-1258.

Abstract
OBJECTIVES Data on the efficacy of vancomycin catheter lock therapy (VLT) for conservative treatment of totally implantable venous access port-related infections (TIVAP-RI) due to CoNS are scarce. The aim of this study was to evaluate the effectiveness of VLT in the treatment of TIVAP-RI due to CoNS in cancer patients. METHODS This prospective, observational, multicentre study included adults with cancer treated with VLT for a TIVAP-RI due to CoNS. The primary endpoint was the success of VLT, defined as no TIVAP removal nor TIVAP-RI recurrence within 3 months after initiation of VLT. The secondary endpoint was 3 month mortality. Risk factors for VLT failure were also analysed. RESULTS One hundred patients were included [men 53%, median age 63 years (IQR 53-72)]. Median duration of VLT was 12 days (IQR 9-14). Systemic antibiotic therapy was administered in 87 patients. VLT was successful in 44 patients. TIVAP could be reused after VLT in 51 patients. Recurrence of infection after completion of VLT occurred in 33 patients, among which TIVAP was removed in 27. Intermittent VLT (antibiotic solution left in place in the TIVAP lumen part of the time) was identified as a risk factor for TIVAP-RI recurrence. At 3 months, 26 deaths were reported; 1 (4%) was related to TIVAP-RI. CONCLUSIONS At 3 months, success of VLT for TIVAP-RI due to CoNS was low. However, removing TIVAP was avoided in nearly half the patients. Continuous locks should be preferred to intermittent locks. Identifying factors of success is essential to select patients who may benefit from VLT.

Home intravenous antibiotherapy and the proper use of elastomeric pumps: Systematic review of the literature and proposals for improved use. Infect Dis Now 2021; 51:39-49. [PMID: 33576336 DOI: 10.1016/j.medmal.2020.10.019] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 04/28/2020] [Accepted: 10/15/2020] [Indexed: 11/30/2022]
Abstract
Over several decades, the economic situation and consideration of patient quality of life have been responsible for increased outpatient treatment. It is in this context that outpatient antimicrobial treatment (OPAT) has rapidly developed. The availability of elastomeric infusion pumps has permitted prolonged or continuous antibiotic administration by dint of a mechanical device necessitating neither gravity nor a source of electricity. In numerous situations, its utilization optimizes administration of time-dependent antibiotics while freeing the patient from the constraints associated with infusion by gravity, volumetric pump or electrical syringe pump and, more often than not, limiting the number of nurse interventions to one or two a day. That much said, the installation of these pumps, which is not systematically justified, entails markedly increased OPAT costs and is liable to expose the patient to a risk of therapeutic failure or adverse effects due to the instability of the molecules utilized in a non-controlled environment, instability that necessitates close monitoring of their use. More precisely, a prescriber must take into consideration the stability parameters of each molecule (infusion duration, concentration following dilution, nature of the diluent and pump temperature). The objective of this work is to evaluate the different means of utilization of elastomeric infusion pumps in intravenous antibiotic administration outside of hospital. Following a review of the literature, we will present a tool for optimized antibiotic prescription, in a town setting by means of an infusion device.

Abstract
Pasteurella multocida , a zoonotic infectious pathogen, is a rare cause of mycotic aneurysms in human hosts. A 76-year-old man was admitted at our emergency unit for a superinfection of his right limb. The patient was initially treated for a knee arthritis. After a first-line antibiotherapy, the patient was referred to the vascular department for the management of a right acute limb ischemia. The work-up revealed a ruptured pseudoaneurysm of the popliteal artery. The ruptured artery was surgically explanted, and a femoropopliteal bypass was then performed. Pasteurella multocida was detected after bacterial analysis of the aneurysm. The postoperative course was uneventful. This case is the first reported case, to our knowledge, of a popliteal artery pseudoaneurysm due to Pasteurella multocida infection.

Abstract
INTRODUCTION Pseudochromhidrosis denotes the production of colourless sweat that acquires colour after coming into contact with exogenous factors such as dyes in clothing, chemicals or chromogenic microorganisms. PATIENTS AND METHODS A 9-year-old girl presented with progressive brown pigmentation predominantly on the nose, forehead, perioral region and cheeks. It was easily removable by rubbing with a moist compress, leaving normal-coloured skin as well as brown pigment on the compress. The same pigmentation recurred within 2h. The patient was not using cosmetics. Bacteriological culture of samples taken by rubbing the skin in affected areas on the face was positive for commensal bacteria of the skin (Actinomyces viscosus, Staphylococcus epidermidis, Cutibacterium acnes and Streptococcus sanguinis). Antibiotic therapy achieved total resolution of symptoms. CONCLUSION Bacteria constitute the most frequent aetiology of pseudochromhidrosis. Where such a cutaneous condition exists, even in the absence of positive bacteriological testing, antibiotic therapy would seem to be indicated as a therapeutic test. Biopsy does not appear to be essential as a first-line approach where a bacterial cause is suspected, but it may be proposed in the event of resistance to antibiotics.

18F-FDG PET/CT as a central tool in the shift from chronic Q fever to Coxiella burnetii persistent focalized infection: A consecutive case series. Medicine (Baltimore) 2016; 95:e4287.

Abstract
Because Q fever is mostly diagnosed serologically, localizing a persistent focus of Coxiella burnetii infection can be challenging. F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) could be an interesting tool in this context.We performed a retrospective study on patients diagnosed with C burnetii infection, who had undergone F-FDG PET/CT between 2009 and 2015. When positive F-FDG PET/CT results were obtained, we tried to determine if it changed the previous diagnosis by discovering or confirming a suspected focus of C burnetii infection.One hundred sixty-seven patients benefited from F-FDG PET/CT. The most frequent clinical subgroup before F-FDG PET/CT was patients with no identified focus of infection, despite high IgG1 serological titers (34%). For 59% (n = 99) of patients, a hypermetabolic focus was identified. For 62 patients (62.6%), the positive F-FDG PET/CT allowed the diagnosis to be changed. For 24 of them, (38.7%), a previously unsuspected focus of infection was discovered. Forty-two (42%) positive patients had more than 1 hypermetabolic focus. We observed 21 valvular foci, 34 vascular foci, and a high proportion of osteoarticular localizations (n = 21). We also observed lymphadenitis (n = 27), bone marrow hypermetabolism (n = 11), and 9 pulmonary localizations.We confirmed thatF-FDG PET/CT is a central tool in the diagnosis of C burnetii focalized persistent infection. We proposed new diagnostic scores for 2 main clinical entities identified using F-FDG PET/CT: osteoarticular persistent infections and lymphadenitis.

Preparing and administering injectable antibiotics: How to avoid playing God. Med Mal Infect 2016; 46:242-68.

Abstract
The emergence of bacterial resistance and the lack of new antibiotics in the pipeline represent a public health priority. Maximizing the quality of antibiotic prescriptions is therefore of major importance in terms of adequate preparation and administration modalities. Adequate preparation prevents the inactivation of antibiotics and is a prerequisite to maximizing their efficacy (taking into account the pharmacokinetic/pharmacodynamic relationship) and to minimizing their toxicity. Many antibiotic guidelines address the choice of drugs and treatment duration but none of them exclusively address preparation and administration modalities. These guidelines are based on the available literature and offer essential data for a proper antibiotic preparation and administration by physicians and nurses. They may lead to a better efficacy and to a reduced antibiotic resistance. Such guidelines also contribute to a proper use of drugs and improve the interaction between inpatient and outpatient care for a better overall management of patients.

Abstract
OBJECTIVE To compare the efficacy of assisted reproductive technology (ART) in women infected with human immunodeficiency virus type 1 (HIV-1) versus HIV-negative controls. DESIGN Retrospective case-control study. SETTING University hospital ART unit. PATIENT(S) Eighty-two women infected with HIV-1 and 82 women as seronegative controls. INTERVENTION(S) Ovarian stimulation, oocytes retrieval, standard in vitro fertilization (IVF) or intracytoplasmic sperm injection, embryo transfer. MAIN OUTCOME MEASURE(S) Clinical pregnancies and live-birth rates. RESULT(S) After oocyte retrieval, all women infected with HIV-1 infected were matched 1:1 to HIV-negative controls according to the following criteria: date of ART attempt, age, parity, main cause of infertility, ART technique, and rank of attempt. Only the first IVF cycle during the study period was considered for each couple. We found no statistically significant differences between the two groups for ovarian stimulation data, fertilization rate, or average number of embryos transferred. The clinical pregnancy rate per transfer was statistically significantly lower for the cases compared with the controls (12% vs. 32%), as were the implantation rate (10% vs. 21%) and the live-birth rate (7% vs. 19%). CONCLUSION(S) In one of the largest studies to pair six factors that influence the results of ART, HIV infection in women was associated with poorer outcomes after ART. These results suggest that women with controlled HIV-1-infection should be counseled not to delay ART in cases of self-insemination failure or other causes of infertility. Fertility preservation by vitrification of oocytes in women whose pregnancy should be delayed may be an important future consideration.

Abstract
INTRODUCTION Bare-metal stents are used to treat arterial stenotic lesions. Morbidity and mortality are less important compared with other techniques. Drug-eluting balloons are often used to treat stent stenosis. We reported the case of a bare-metal stent infection after drug-eluting balloon and a review on the subject. MATERIAL AND METHOD Two weeks after percutaneous transluminal angioplasty with paclitaxel-eluting balloon and a bare-metal stent, our patient presented an infection of the stent. Diagnosis was based on the clinical presentation, positron emission tomography findings and isolation of Propionibacterium granulosum in repeated blood cultures. Adapted antibiotic therapy was given for three months with removal of the surgical bare-stent. Antibiotic therapy was interrupted after a second positron emission tomography. A literature search (PubMed and Cochrane) was performed on the subject. RESULTS We found 49 cases of peripheral bare-metal stent infection including our patient. This is a rare but serious complication with a high morbidity (25% amputation rate) and mortality (30%). It seems to be underestimated. Treatment is based on surgical ablation of the bare-metal stent and intravenous antibiotics. The role of the paclitaxel-eluting balloon is not clearly established but some authors believe that it can produce a local immunosuppression. CONCLUSION We report the first case of bare-metal stent infection after paclitaxel-eluting balloon. This complication is rare and difficult to diagnose. Manifestations are often limited to skin signs. Functional and vital prognosis is poor.

Abstract
OBJECTIVE The emergence of extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae has resulted in the increase of carbapenem prescriptions. The objective of our study was to determine the appropriateness of carbapenem prescriptions from initiation to reassessment of treatment, between 2009 and 2011. PATIENTS AND METHOD A questionnaire drafted by infectious diseases specialists (IDS) and microbiologists was used to collect clinical and microbiological data concerning carbapenem prescriptions in 2009 and 2011. An IDS then compared the results to assess carbapenem prescription compliance with our hospital's local recommendations. RESULTS Seventy-one prescriptions were included in 2009 and 32 in 2011. The carbapenem treatment had been most frequently probabilistic to treat nosocomial infections. The microbiological data revealed that the number of multidrug-resistant (MDR) infections had increased between 2009 and 2011, especially infections involving ESBL-producing Enterobacteriaceae. At treatment reassessment, in 2009 and 2011, 15 (21%) and 12 (38%) carbapenem prescriptions were appropriate and continued. Overall, when comparing the 2 periods, prescriptions complied with local guidelines from initiation to reassessment of treatment without any statistically significant difference (68% in 2009 and 75% in 2011). CONCLUSION Our study results showed that MDR infections had increased and especially infections due to ESBL-producing Enterobacteriaceae; this was consistent with epidemiological data. We also proved that most carbapenem prescriptions were compliant with recommendations. The increased mobile IDS interventions in medical and surgical departments helped reach this rate of compliance. Carbapenem stewardship may be promoted even in a difficult epidemiological context, especially with IDS interventions for the duration of treatment or at treatment reassessment.

Abstract
It was demonstrated that combination antiretroviral therapy (cART) reduces the HIV-1 viral load (VL) in the blood and the seminal compartment. Some studies have reported that the seminal HIV-1 VL is undetectable in individuals with an undetectable blood plasma viral load (bpVL) under cART. However, some recent studies have demonstrated that seminal HIV-1 RNA may still be detected, and potentially infectious, even in the case of an undetectable bpVL. The aim of this retrospective study was to determine the detection rate of a seminal VL and whether shedding could be intermittent over a very short time. From January 2006 to December 2011, 88 HIV-1 infected men, enrolled in an Assisted Reproduction program, provided 306 semen samples, corresponding to 177 frozen sperm samples (two samples delivered at a one-hour interval (n = 129) or one sample (n = 48)). All enrolled men were under cART, with an undetectable bpVL for more than 6 months. HIV-1 RNA was quantified in seminal plasma using a Roche COBAS Ampliprep COBAS TaqMan HIV-1 test. Seminal HIV-1 RNA was detected in 23 samples (7.5%) from 17 patients (19.3%). This detection rate was stable over years. With regards to the freezing of two samples delivered at a one-hour interval, the proportion of discordance between the first and second samples was 9.3% (12/129). Our results confirm the intermittent shedding of HIV-1 in semen. While this finding has been shown by studies examining longer time intervals, to our knowledge, this has never been demonstrated over such a short time interval.

Abstract
OBJECTIVE We retrospectively studied daptomycin use during 2010 at the Bichat-Claude-Bernard teaching-hospital (Paris) to observe the evolution of daptomycin prescriptions. PATIENTS AND METHODS Twenty-one patients were included and several parameters were documented: site of infection, bacterial species involved, reason for daptomycin use, dose and clinical outcome. RESULTS Ninety-five percent of daptomycin prescritions were off-label and most did not comply with local guidelines. Fifteen of the 21 patients were cured (71%), including 9 patients of the 12 with off-label and off-local recommendation prescriptions (75%). Osteitis and Enterococcus spp endocarditis were the new indications. Daptomycin was increasingly used at higher doses: 52% of our patients were given doses above 6mg/kg. Staphylococcus spp. was the most frequent pathogen responsible for infection is our patients, followed by Enterococcus spp. CONCLUSION Daptomycin use is likely to evolve because of its effectiveness in the treatment of osteitis, left-sided and Enterococcus spp. infective endocarditis. It is generally used at higher doses, which are well tolerated. However, therapeutic monitoring needs to be developed. The antibiotic commission of our hospital gave new recommendations for daptomycin use in 2011.

Abstract
BACKGROUND Whether pregnancy has an impact on the evolution of CD4 cell counts in women treated with highly potent antiretrovirals before conception remains largely unknown. METHODS Among patients enrolled in the ANRS CO8 (APROCO/COPILOTE) cohort, we selected all women aged between 18 and 50 years at initiation of combination antiretroviral therapy (cART). Slopes of CD4 cell counts during follow-up were estimated using mixed longitudinal models with time-dependent indicators for pregnancy and delivery. RESULTS Of the 260 selected HIV-infected women, a pregnancy occurred in 39 women in a median follow-up time of 66 months. Women who became pregnant had higher CD4 cell count at baseline but this difference progressively lessened during follow-up because they had a slower increase than women who did not become pregnant. The estimated slope of CD4 cell count decreased significantly from +2.3 cells/muL/month before pregnancy and in women who did not become pregnant to -0.04 cells/microL/month after delivery (P=0.0003). CONCLUSION A significant increase in CD4 cell count may be preferable before pregnancy in women treated with cART, in order to overcome the evolution observed after pregnancy.

Abstract
Objectifs Afin d'analyser les différences possibles d'évaluation entre les équipes opérationnelles épidémiologiques et cliniciennes dans la gestion d'une maladie épidémique émergente, et d'en tirer un enseignement pour la gestion de crises ultérieures, les caractéristiques des patients suspects de syndrome respiratoire aigu sévère (SRAS) hospitalisés dans un service parisien ont été décrites. Patients et méthodes Les 90 patients hospitalisés du 16 mars au 30 avril 2003 furent inclus dans cette étude prospective. Les données échangées avec les institutions sanitaires locales permirent à la fois une classification de cas officielle (« possibles », « probables », « exclus ») et une classification locale basée sur une adaptation de celle-ci, incluant une catégorie supplémentaire dans la graduation du risque, intermédiaire entre « possible » et « exclu » (« douteux »). Résultats L'évaluation initiale différait dans 39 % des cas (n = 35), sur des arguments épidémiologiques (n = 24) ou clinicobiologiques (n = 11). L'évaluation finale divergeait dans 54 % des cas (n = 47). Tous les patients furent officiellement considérés comme des cas « exclus » de SRAS, alors que 47 demeuraient des cas « possibles » ou « douteux » selon les cliniciens. Conclusion Une différence de perception existait dans environ 40 % des cas, sans impact en termes de diffusion épidémique ou d'exposition nosocomiale, puisqu'aucun cas probable de SRAS n'a été retenu parmi ces patients ou leur entourage. De la confrontation de ces perceptions différentes, mais complémentaires, peuvent émerger des enseignements enrichissant la gestion interdisciplinaire d'épidémies ultérieures.

Abstract
Diverses infections émergentes sont rapportées depuis la mise en place d'une surveillance épidémiologique accrue. Ces infections peuvent compromettre le bon déroulement d'une grossesse, en mettant en jeu le pronostic vital maternel ou le développement de l'enfant lors d'une transmission verticale. À travers une revue récente de la littérature, nous rapportons les conséquences de ces virus émergents les plus cités (H5N1, Coronavirus du SRAS, Chikungunya, virus du Nil occidental) et discutons la prise en charge périnatale.

Abstract
OBJECTIVE To describe the implementation and initial results of a specific educational and counseling intervention to examine and improve adherence to antiretroviral therapy (ARV) in HIV-infected patients. METHOD Four patient profiles were defined: 1) discontinuation and 2) failure: patients with virological failure (defined as two consecutive viral loads>200 copies/mL) at ARV discontinuation or under treatment, both seen after the fact; 3) preparation: naive patients seen before starting treatment, and 4) reinforcement: patients in treatment seen for counseling to prevent virological failure. A clinical psychologist, nurse and hospital pharmacist jointly conducted the session. Data collected include standardized information about the characteristics of HIV infection and ARV regimens, and demographic, behavioral, social and cultural indicators. CD4 cell counts and HIV viral loads were recorded at D0, M1, M3, M9 and M12. The effectiveness of the adherence intervention was defined separately for each patient profile based on some combination of taking or restarting an ARV regimen, virological response, and M12 follow-up. RESULTS The study included 139 patients between November 1998 and April 2000. The intervention was defined as effective in 50% and 40% of the discontinuation (n=26) and failure (n=61) patients respectively, 84% of those with preparation profile (n=37) and 93% (14/15) of reinforcement patients. Only undetectable HIV viral load at M3 was significantly associated with the effectiveness of the adherence intervention for all 4 profiles. The preventive interventions (preparation and reinforcement) were less effective in patients from outside Europe (p=0.013). CONCLUSION The adherence intervention was more effective in preventing virological failure than in restoring ARV effectiveness among patients who had already experienced virological failure. It should therefore be proposed primarily before starting ARV, to prevent failure in treatment-naive patients, especially those from outside Europe.

Abstract
INTRODUCTION Tuberculosis can be responsible for myocardial damage, the frequency of which is probably underestimated because of the difficulty in its diagnosis. We studied the contribution of cardiac magnetic resonance imaging (MRI) in three patients. OBSERVATIONS Three patients were treated for disseminated tuberculosis. They had moderate cardiac abnormalities (tachycardia, dyspnoea on effort). The electrocardiogram was normal in 2 patients and the echocardiography showed localized hyperkinesias. Cardiac MRI revealed intra-myocardial nodular gadolinium enhancement and hyperkinesias. The clinical outcome in the 3 patients was favourable following anti-tuberculosis therapy; one patient was also administered corticosteroids. DISCUSSION Cardiac MRI is a non-invasive examination that brought important arguments for the diagnosis of tubercular myocarditis in the 3 patients.

Abstract
Immune reconstitution inflammatory syndrome (IRIS) occurred in 16 of 37 antiretroviral-naive patients who were treated subsequently for tuberculosis and human immunodeficiency virus (HIV) type 1 infection. IRIS was related to increases in the CD4 cell percentage and in the ratio of CD4 cells to CD8 cells after 1 month of antiretroviral therapy and to dissemination of tuberculosis. These results have implications for the diagnosis of IRIS and the understanding of its pathogenesis.

Abstract
Efavirenz has now become commonly used to treat HIV infection. Neuropsychiatric disorders have been reported in patients treated with efavirenz. Several factors often make it hard to determine the cause of these disorders: HIV infected patients take many different drugs, they may suffer from various organ diseases, and may also be heavily affected by problems in their everyday life. The French experts group working on neuropsychiatric side effects of efavirenz has undertaken a review of these disorders with the aim to identify: (1) semiology, (2) epidemiology in the global population, in HIV infected patients, and in patients treated with efavirenz. The expert group suggests recommendations to manage these disorders.

Abstract
To reduce the number of daily pills for improving adherence to antiretrovirals, 17 protease inhibitor-treated patients receiving toxoplasmic encephalitis (TE) standard maintenance therapy were instead given cotrimoxazole 960 mg twice daily. After a median follow-up of 31 months, one relapsed after three months, TE relapse incidence = 2.1 cases per 100 patient-years (95% confidence interval, 0.05-11.3). This strategy could be useful for patients awaiting immune reconstitution which allows the interruption of TE maintenance therapy.

Abstract
Whereas valacyclovir is widely used and is recommended by some authors in moderately immunocompromised HIV-infected patients, its use has not been validated by clinical studies. We report a case of herpes zoster in an HIV-infected patient for whom neurologic complication was not avoided despite valacyclovir therapy. Clinical outcome was favorable after intravenous acyclovir. This case suggests careful monitoring of valacyclovir in HIV-infected patients is necessary.

Abstract
To describe the rate of response to an antibiotic-lock technique (ALT) in the treatment of venous access port (VAP)--related bacteremia and to analyze the role of the reservoir in the persistence of infection, we reported the data from 12 human immunodeficiency virus--infected and 8 oncologic patients with VAP-related bacteremia. The ALT consisted of intracatheter delivery of antibiotics and was associated with a systemic antibiotic infusion. We monitored clinical manifestations and performed qualitative and quantitative blood cultures during and at the end of the treatment. Four patients had catheters removed before antibiotic treatment. Of the 16 patients who were treated with the ALT, 5 (31%) were cured, as determined by negative cultures of blood and of samples from the catheter; 2 (12.5%) were cured but had recurrent infection with another microorganism; and 9 (56%) had persistent positive cultures of blood and of samples from the tip, reservoir, or both of the VAP. Limited efficacy of the ALT might be explained by the presence of deposits of fibrin that include clusters of bacteria inside the reservoir of the port.

Abstract
BACKGROUND Restoration of immunocompetence in HIV-infected patients after antiretroviral treatment can have unexpected effects. CASE REPORTS An unusual course of treated tuberculosis was observed in four HIV-infected patients soon after initiation of antiretroviral therapy. These patients developed fever and enlarged necrotic adenopathies despite an efficacious antituberculous therapy. They were in the initial stage of their antituberculous therapy that had been initiated a mean 12 days prior to initiation of antiretroviral therapy. The antiretroviral therapy led to an undetectable HIV load within 2 months. DISCUSSION These unusual features, which also occurred with an increase in CD4 cell counts, could be related to the immunological restoration and to the reappearance of delayed type hypersensitivity. The onset of antiretroviral therapy could thus be delayed by several weeks in HIV-infected patients treated for active tuberculosis and who have never received antiretroviral therapy.

Abstract
From March to July 1996, 61 patients with CD4<50/mm(3)began a therapy with protease inhibitors. Increase and maintenance of CD4>100/mm(3) was observed in 39/61 patients with a protective effect for occurrence of AIDS or death. This immunological response was correlated with the duration of the virological response. However, 38% of patients with long-term immunological response never had a undetectable viral load.

Abstract
OBJECTIVE To determine the specific characteristics of Streptococcus bovis infective endocarditis (IE) by reviewing our own experience of S. bovis IE. METHODS Twenty episodes of definite S. bovis IE were reviewed in 20 patients hospitalized from 1980 to 1996. RESULTS The mean age was 62 +/- 14 years, and 14 (70%) patients had no known predisposing cardiac condition. The principal antimicrobials used were penicillin G (N = 10) and amoxycillin (N = 8). Surgery was required in four (20%) patients. Neurologic complications occurred in eight (40%) patients, after initiation of therapy in six (75%) (mean time: 14 days). An unfavorable outcome was observed in four of 20 patients and tended to be more frequent in patients who had had neurologic complications (P = 0.10). Colonic tumors were present in 11 of 16 (69%) patients. CONCLUSIONS Advanced age, occurrence of IE on presumably normal valves, high rate of neurologic complications, associated gastrointestinal diseases and low mortality rate during initial follow-up are characteristic features of S. bovis IE observed in this study.

Abstract
FAILURES OF ANTIBIOTIC TREATMENT: The number of failures after treatment of acute middle ear infections with the 2 main antibiotics prescribed (amoxicillin and the combination amoxicillin-clavulanic acid) is on the rise. These failures appear to be related to increased resistance of the 2 principal pathogens, pneumococci and Hemophilus influenzae. A NEW FORMULATION: In order to reduce the rate of failure, it has been necessary to both increase the dose of penicillin to overcome the reduced susceptibility of pneumococci to penicillin and to prescribe a beta-lactam because of the frequent isolation of beta-lactamase producing Hemophilus influenzae. A new formulation has been developed where the amoxicillin-clavulanic acid dose is 14 to 1. This allows a daily dose of 80 mg/kg for amoxicillin and 6.4 mg/kg for clavulanic acid. In one open multicentric study including 51 pediatric patients aged 3 to 48 months with acute middle ear infections, it was demonstrated that this new formulation can be very effective in eradicating the causal agents of acute middle ear infections, including pneumococci and penicillin-resistant Hemophilus. RECOMMENDATIONS FOR GOOD EFFICACY: Amoxicillin must always be prescribed, either alone or in combination with clavulanic acid, at the dose of 45 to 50 mg/kg b.i.d. the amoxicillin-clavulanic acid combination should be preferred for children under 2 years due to the risk of beta-lactamase producing Hemophilus.

Abstract
The accumulation of infected clots under the silicone septum of the reservoir of venous access ports (VAPs) has been reported. We analyzed the relationship between these deposits and the occurrence of VAP-related bloodstream infections (VAP-BSIs) by (1) evaluating the accuracy of paired quantitative blood cultures for diagnosing VAP-BSI before the removal of the device and (2) assessing the accuracy of cultures of the tip and septum (i.e., the internal lumen of the VAP) for diagnosing VAP-BSI after removal of the device. Over a 16-month period, all VAPs removed were prospectively investigated. Before VAP removal, paired quantitative blood cultures were 77% sensitive and 100% specific and had a positive predictive value of 100% and a negative predictive value of 98% for diagnosing VAP-BSI. After VAP removal, tip culture was only 46% sensitive, whereas septum culture was 93.3% sensitive for confirming the diagnosis of VAP-BSI. Thus infected deposits that accumulate under the VAP septum are the source of VAP-BSI.
