Duration of severe and moderate symptoms in pharyngitis by cause.

OBJECTIVE: This study aimed to assess the cause of acute pharyngitis and determine the duration of severe and moderate symptoms based on the aetiology. DESIGN: Prospective observational study. SITE: One urban health care centre. PARTICIPANTS: Patients aged 15 or older with acute pharyngitis were included. INTERVENTIONS: Bacterial identification was carried out in the microbiology lab using MALDI-TOF in two throat samples. Patients received a symptom diary to return after one week. MAIN MEASUREMENTS: Number of days with severe symptoms, scoring 5 or more in any of the symptoms included in the symptom diary, and moderate symptoms, scoring 3 or more. RESULTS: Among the 149 patients recruited, beta-haemolytic streptococcus group A (GABHS) was the most common aetiology. Symptoms and signs alone as well as the mean Centor score cannot distinguish between GABHS and other bacterial causes in patients with acute pharyngitis. However, there was a trend indicating that infections caused by Streptococcus dysgalactiae and Streptococcus agalactiae presented more severe symptoms, whereas infections attributed to the Streptococcus anginosus group, Fusobacterium spp., and those where oropharyngeal microbiota was isolated tended to have milder symptoms. S. dysgalactiae infections showed a trend towards longer severe and moderate symptom duration. CONCLUSION: GABHS was the most prevalent, but group C streptococcus caused more severe and prolonged symptoms.

Effects of virtual tour on perioperative pediatric anxiety.

BACKGROUND: There is a high incidence of perioperative anxiety in the pediatric population, with adverse side effects, such as emergency delirium and maladaptive postoperative behaviors. AIMS: The study's objective was to compare the level of preoperative anxiety in children after standard preparation plus a virtual tour of the operating room vs. standard preparation alone. PATIENTS/METHODS: This was a prospective single-center, randomized, controlled, blinded trial with parallel assignment, registered as NCT04043663. Eligible subjects were healthy children (ASA I-II) aged 4-12, scheduled for outpatient surgery. Five visits were conducted during the study, two at the hospital and three over the phone. Variables assessed were child's anxiety through the modified Yale Perioperative Anxiety Scale, demographic data, cooperation with induction through the Induction Compliance Checklist, preoperative parental anxiety through the State-Trait Anxiety Inventory and Anxiety Visual Analog Scale, the postoperative delirium degree through the Pediatric Anesthesia Emergence Delirium Scale, the presence of behavioral changes through the Post Hospitalization Behavior Questionnaire for Ambulatory Surgery, and the overall parental satisfaction. RESULTS: A total of 125 participants were included; 61 (48.8%) of them were randomized to the Virtual Tour Group (VT+) and 64 (51.2%) to the Non-virtual Tour Group (VT-). Yale Preoperative Anxiety Scale results in VT+ vs. VT- were mean 27.26 vs. 32.57, and median 23.4 (CI 95% 23.4-23.4) vs. 23.4 (CI 95% 23.4-33.4), (p = .0086). In the VT+ group, satisfaction was higher for questions one (p = .0213), three (p = <.0001), and four (p = .0130). Throughout the study, we observed a significant reduction in perioperative anxiety in the VT+ group, facilitating anesthetic induction in perfect (p = .018) and moderate compliance (p = .0428). The other variables did not show statistically significant differences. CONCLUSION: Our study confirms previous studies that found virtual tours for perioperative patients may reduce perioperative anxiety and improve satisfaction. We found no impact on longer-term outcomes.

Second primary cancers: a retrospective analysis of real world data using the enhanced medical research engine ConSoRe in a French comprehensive cancer center.

BACKGROUND: Second primary cancers (SPC) account for 18% of all cancers. We used the enhanced medical/health data mining tool ConSoRe to search aggregated data, analyze electronic patient records (EPR), and better characterize patients with SPC. METHODS: This retrospective cohort study used ConSoRe to identify EPRs from patients with SPC referred to the regional cancer center Leon Bérard from 1993 to 2017, and examined characteristics of patients with SPC, frequencies of first primary cancer (FPC) localization in the global population of patients with SPC, and time to SPC. Data set was extracted on January 1, 2018. RESULTS: Among 296,530 EPRs, we identified 157,187 patients with FPC, including 13,002 (8%) patients with SPC. Between 2000 and 2010, the rate of SPC was 34%, and 52% of SPC were identified in the last years (2010-2017). In men, main cancers were head and neck cancer, lymphoma, and prostate carcinoma accounting for 15.6%, 12.8%, and 10.5% of FPC, while the three most common SPC were head and neck cancer (13.2%), lung cancer (11.8%) and lymphoma (9.2%). In women, breast cancers, lymphoma, and skin cancers accounted for 48.8%, 8%, and 5.1% of first cancers, and for 31.1%, 7% and 6% of SPC. CONCLUSION: The data mining tool ConSoRe contributes to access to real world data, and to better characterize patients with SPC. Expanding such approach to any comprehensive center will allow a global overview of the follow-up of patients with cancer, and help to improve long-term management and adapt surveillance.

Cost-effectiveness of an exercise and nutritional intervention versus usual nutritional care during adjuvant treatment for localized breast cancer: the PASAPAS randomized controlled trial.

We undertook a cost-effectiveness analysis (CEA) to compare an exercise and nutritional program with the usual nutritional care concomitant to adjuvant chemotherapy in localized breast cancer patients. The CEA was designed as part of the interventional, controlled, randomized, single-center, open-label PASAPAS study. Breast cancer patients receiving first-line adjuvant chemotherapy at a French Comprehensive Cancer Center were randomized 2:1 to a 6-month exercise program of supervised indoor and outdoor group sessions in addition to usual nutritional care (exercise arm) or a usual nutritional care group receiving dietary and physical activity counseling (control arm). Costs were assessed from the French national insurance perspective (in Euros, 2012). Incremental cost-effectiveness ratios (ICERs) were calculated for four criteria: body mass index, waist circumference, body fat percentage, and estimated aerobic capacity. Uncertainty around the ICERs was captured by a probabilistic analysis using a non-parametric bootstrap method. The analysis was based on 60 patients enrolled between 2011 and 2013. Average intervention costs per participant were €412 in the exercise arm (n = 41) and €117 (n = 19) in the control arm. Total mean costs were €17,344 (standard deviation 9,928) and €20,615 (standard deviation 14,904), respectively, did not differ significantly (p = 0.51). The 6-month exercise program was deemed to be cost-effective compared with usual care for the estimated aerobic capacity. Multicenter randomized studies with long-term costs and outcomes should be done to provide additional evidence. Clinical trial: The PASAPAS study is registered under ClinicalTrials.gov. Trial registration ID: NCT01331772.

Contribution of Candida biomarkers and DNA detection for the diagnosis of invasive candidiasis in ICU patients with severe abdominal conditions.

BACKGROUND: To assess the performance of Candida albicans germ tube antibody (CAGTA), (1 → 3)-ß-D-glucan (BDG), mannan antigen (mannan-Ag), anti-mannan antibodies (mannan-Ab), and Candida DNA for diagnosing invasive candidiasis (IC) in ICU patients with severe abdominal conditions (SAC). METHODS: A prospective study of 233 non-neutropenic patients with SAC on ICU admission and expected stay ≥ 7 days. CAGTA (cutoff positivity ≥ 1/160), BDG (≥80, 100 and 200 pg/mL), mannan-Ag (≥60 pg/mL), mannan-Ab (≥10 UA/mL) were measured twice a week, and Candida DNA only in patients treated with systemic antifungals. IC diagnosis required positivities of two biomarkers in a single sample or positivities of any biomarker in two consecutive samples. Patients were classified as neither colonized nor infected (n = 48), Candida spp. colonization (n = 154) (low-grade, n = 130; high-grade, n = 24), and IC (n = 31) (intra-abdominal candidiasis, n = 20; candidemia, n = 11). RESULTS: The combination of CAGTA and BDG positivities in a single sample or at least one of the two biomarkers positive in two consecutive samples showed 90.3 % (95 % CI 74.2-98.0) sensitivity, 42.1 % (95 % CI 35.2-98.8) specificity, and 96.6 % (95 % CI 90.5-98.8) negative predictive value. BDG positivities in two consecutive samples had 76.7 % (95 % CI 57.7-90.1) sensitivity and 57.2 % (95 % CI 49.9-64.3) specificity. Mannan-Ag, mannan-Ab, and Candida DNA individually or combined showed a low discriminating capacity. CONCLUSIONS: Positive Candida albicans germ tube antibody and (1 → 3)-ß-D-glucan in a single blood sample or (1 → 3)-ß-D-glucan positivity in two consecutive blood samples allowed discriminating invasive candidiasis from Candida spp. colonization in critically ill patients with severe abdominal conditions. These findings may be helpful to tailor empirical antifungal therapy in this patient population.

Influence of chronic illnesses and underlying risk conditions on the incidence of pneumococcal pneumonia in older adults.

OBJECTIVE: To investigate hospitalizations from pneumococcal pneumonia in older adults with specific underlying chronic conditions, evaluating the influence of these conditions in developing pneumonia. METHODS: Population-based cohort study involving 27,204 individuals ≥ 60 years old in Southern Catalonia, Spain. All cases of hospitalization from pneumococcal pneumonia (bacteremic and nonbacteremic) were collected since 01/12/2008 until 30/11/2011. Cox regression was used to calculate hazards ratio (HR) and estimate the association between baseline conditions and the risk of developing pneumococcal pneumonia. RESULTS: Maximum incidences (per 1000 person-years) appeared among patients with history of prior pneumonia (14.6), nursing home residents (12.8), persons with immunodeficiency/asplenia (7.7) and patients with chronic pulmonary disease (7.6). In multivariable analysis, age (HR: 1.05), nursing home residence (HR: 4.59), history of prior pneumonia (HR: 3.58), stroke (HR: 2.50), chronic heart disease (HR: 1.53), chronic pulmonary disease (HR: 4.09), diabetes mellitus (HR: 1.66), smoking (HR: 1.69) and immunosuppressive medication (HR: 1.87) appeared significantly associated with an increased risk of pneumococcal pneumonia. CONCLUSION: Our data support that nursing home residence, chronic pulmonary disease and immunocompromising conditions are the underlying conditions most strongly associated with an increasing risk of pneumococcal pneumonia in older adults. This data underline the need for better prevention strategies among these persons.

HEDEN Pain Scale: A Shortened Behavioral Scale for Assessment of Prolonged Cancer or Postsurgical Pain in Children Aged 2 to 6 Years.

Few observational scales are available for assessing chronic or recurrent pain in children with cancer because overt behavioral signs of chronic pain dissipate as time passes, making them difficult to detect reliably. The Douleur Enfant Gustave Roussy (DEGR) scale developed by Gauvain-Piquard to monitor prolonged pain in children with cancer aged 2-6 years is currently the only validated tool available for this purpose, but is time consuming and difficult to use in daily clinical practice. To shorten composite measurement scales, we developed the Hétero Evaluation Douleur Enfant (HEDEN) scale from the DEGR scale. We present here the process and validation of this scale. Expert consensus was used for the elaboration of HEDEN: 5/10 DEGR items were chosen with three rating levels. Concurrent validity was tested in a first cohort with correlation analysis between HEDEN and DEGR. The HEDEN scale was then validated in a second cohort. In the first step, the study (59 children) showed acceptable correlation between DEGR and HEDEN (r = 0.5), with good reliability (α = 0.61), and interrater agreement (r = 0.62). Subsequent validation in 48 children showed a significant correlation between DEGR and HEDEN (r = 0.6). Reliability was good (α = 0.75), with excellent interrater agreement [r = 0.67 (95% CI: 0.48-0.79)]. On average, the evaluation took 23 minutes (SD = 10.4) for DEGR versus 4.42 minutes (SD = 5.9) for HEDEN. This study shows a good correlation between HEDEN and DEGR scales. HEDEN allows accurate assessment of prolonged pain in young children with cancer.

Academic difficulties and occupational outcomes of adult survivors of childhood leukemia who have undergone allogeneic hematopoietic stem cell transplantation and fractionated total body irradiation conditioning.

We studied academic and employment outcomes in 59 subjects who underwent allogeneic hematopoietic stem cell transplantation (a-HSCT) with fractionated total body irradiation (fTBI) for childhood leukemia, comparing them with, first, the general French population and, second, findings in 19 who underwent a-HSCT with chemotherapy conditioning. We observed an average academic delay of 0.98 years among the 59 subjects by Year 10 of secondary school (French class Troisième), which was higher than the 0.34-year delay in the normal population (P < .001) but not significantly higher than the delay of 0.68 years in our cohort of 19 subjects who underwent a-HSCT with chemotherapy. The delay was dependent on age at leukemia diagnosis, but not at fTBI. This delay increased to 1.32 years by the final year of secondary school (Year 13, Terminale) for our 59 subjects versus 0.51 years in the normal population (P = .0002), but did not differ significantly from the 1.08-year delay observed in our cohort of 19 subjects. The number of students who received their secondary school diploma (Baccalaureate) was similar to the expected rate in the general French population for girls (observed/expected = 1.02) but significantly decreased for boys (O/E = 0.48; CI: 95%[0.3-0.7]). Compared with 13.8% of the general population, 15.3% of the cancer survivors received no diploma (P = NS). Reported job distribution did not differ significantly between our cohort of childhood cancer survivors and the general population except that more female survivors were employed in intermediate-level professional positions. Academic difficulties after fTBI are common and their early identification will facilitate educational and professional achievement.

Clinical and Microbiological Impact of Implementing a Decision Support Algorithm through Microbiologic Rapid Diagnosis in Critically Ill Patients: An Epidemiological Retrospective Pre-/Post-Intervention Study.

BACKGROUND: Data on the benefits of rapid microbiological testing on antimicrobial consumption (AC) and antimicrobial resistance patterns (ARPs) are scarce. We evaluated the impact of a protocol based on rapid techniques on AC and ARP in intensive care (ICU) patients. METHODS: A retrospective pre- (2018) and post-intervention (2019-2021) study was conducted in ICU patients. A rapid diagnostic algorithm was applied starting in 2019 in patients with a lower respiratory tract infection. The incidence of nosocomial infections, ARPs, and AC as DDDs (defined daily doses) were monitored. RESULTS: A total of 3635 patients were included: 987 in the pre-intervention group and 2648 in the post-intervention group. The median age was 60 years, the sample was 64% male, and the average APACHE II and SOFA scores were 19 points and 3 points. The overall ICU mortality was 17.2% without any differences between the groups. An increase in the number of infections was observed in the post-intervention group (44.5% vs. 17.9%, p < 0.01), especially due to an increase in the incidence of ventilator-associated pneumonia (44.6% vs. 25%, p < 0.001). AC decreased from 128.7 DDD in 2018 to 66.0 DDD in 2021 (rate ratio = 0.51). An increase in Pseudomonas aeruginosa susceptibility of 23% for Piperacillin/tazobactam and 31% for Meropenem was observed. CONCLUSION: The implementation of an algorithm based on rapid microbiological diagnostic techniques allowed for a significant reduction in AC and ARPs without affecting the prognosis of critically ill patients.

Survival of bronchopulmonary cancers according to radon exposure.

Introduction: Residential exposure is estimated to be responsible for nearly 10% of lung cancers in 2015 in France, making it the second leading cause, after tobacco. The Auvergne-Rhône-Alpes region, in the southwest of France, is particularly affected by this exposure as 30% of the population lives in areas with medium or high radon potential. This study aimed to investigate the impact of radon exposure on the survival of lung cancer patients. Methods: In this single-center study, patients with a histologically confirmed diagnosis of lung cancer, and newly managed, were prospectively included between 2014 and 2020. Univariate and multivariate survival analyses were carried out using a non-proportional risk survival model to consider variations in risk over time. Results: A total of 1,477 patients were included in the analysis. In the multivariate analysis and after adjustment for covariates, radon exposure was not statistically associated with survival of bronchopulmonary cancers (HR = 0.82 [0.54-1.23], HR = 0.92 [0.72-1.18], HR = 0.95 [0.76-1.19] at 1, 3, and 5 years, respectively, for patients residing in category 2 municipalities; HR = 0.87 [0.66-1.16], HR = 0.92 [0.76-1.10], and HR = 0.89 [0.75-1.06] at 1, 3, and 5 years, respectively, for patients residing in category 3 municipalities). Discussion: Although radon exposure is known to increase the risk of lung cancer, in the present study, no significant association was found between radon exposure and survival of bronchopulmonary cancers.

Clinical effectiveness of pneumococcal vaccination against acute myocardial infarction and stroke in people over 60 years: the CAPAMIS study, one-year follow-up.

BACKGROUND: Conflicting results have been recently reported evaluating the relationship between pneumococcal vaccination and the risk of thrombotic vascular events. This study assessed the clinical effectiveness of the 23-valent polysaccharide pneumococcal vaccine (PPV23) against acute myocardial infarction and ischaemic stroke in older adults. METHODS: Population-based prospective cohort study conducted from December 1, 2008 until November 30, 2009, including all individuals ≥ 60 years-old assigned to nine Primary Care Centres in Tarragona, Spain (N = 27,204 individuals). Primary outcomes were hospitalisation for acute myocardial infarction and/or ischaemic stroke. All cases were validated by checking clinical records. The association between pneumococcal vaccination and the risk of each outcome was evaluated by Multivariable Cox proportional-hazard models (adjusted by age, sex, influenza vaccine status, presence of comorbidities and cardiovascular risk factors). RESULTS: Cohort members were followed for a total of 26,444 person-years, of which 34% were for vaccinated subjects. Overall incidence rates (per 1000 person-years) were 4.9 for myocardial infarction and 4.6 for ischaemic stroke. In the multivariable analysis, vaccination was associated with a marginally significant 35% lower risk of stroke (hazard ratio [HR]: 0.65; 95% confidence interval [CI]: 0.42-0.99; p = 0.046). We found no evidence for an association between pneumococcal vaccination and reduced risk of myocardial infarction (HR: 0.83; 95% CI: 0.56-1.22; p = 0.347). CONCLUSIONS: Our data supports a benefit of PPV23 against ischaemic stroke among the general population over 60 years, suggesting a possible protective role of pneumococcal vaccination against some acute thrombotic events.

Development and validation of a delirium risk prediction preoperative model for cardiac surgery patients (DELIPRECAS): An observational multicentre study.

STUDY OBJECTIVE: To develop and validate a delirium risk prediction preoperative model for patients undergoing cardiac surgery. DESIGN: Observational prospective multicentre study. SETTING: Six intensive care units in Spain. PATIENTS: 689 patients undergoing cardiac surgery consecutively, aged ≥18 years. MEASUREMENTS: The primary outcome measure was the development of delirium, diagnosed using the Confusion Assessment Method in Intensive Care Units (CAM-ICU), during the stay in the intensive care unit after cardiac surgery. MAIN RESULTS: The model was developed with 345 consecutive patients undergoing cardiac surgery at six hospitals and validated with another 344 patients from the same hospitals. The prediction model contained four preoperative risk factors: age over 65 years, Mini-Mental State Examination (MMSE) score of 25-26 points (possible impairment of cognitive function) or < 25 (impairment of cognitive function), insomnia needing medical treatment and low physical activity (walk less than 30 min a day). The model had an area under the receiver operating characteristics curve of 0.825 (95% confidence interval: 0.76-0.89). The validation resulted in an area under the curve of 0.79 (0.73-0.85) and the pooled area under the receiver operating characteristics curve (n = 689) was 0.81 (0.76-0.85). We stratified patients in groups of low (0%-20%), moderate (> 20%-40%), high (> 40%-60%) and very high (> 60%) risk of developing delirium, with a positive and negative predictive value for the very high risk group of 70.97% and 85.56%, respectively. CONCLUSION: The DELIPRECAS model (DELIrium PREvention CArdiac Surgery), consisting of four well-defined clinical risk factors, can predict in the preoperative period the risk of developing postoperative delirium in patients undergoing cardiac surgery. An automatic version of the risk calculator is available.

Systematic Screening for Occupational Exposures in Lung Cancer Patients: A Prospective French Cohort.

Occupational lung cancers are under-reported and under-compensated worldwide. We assessed systematic screening for occupational exposure to carcinogens combining a self-administered questionnaire and an occupational consultation to improve the detection of occupational lung cancers and their compensation. Social deprivation and the costs of this investigation were estimated. Patients with lung cancer received a self-administered questionnaire to collect their job history, potential exposure to carcinogens and deprivation. A physician assessed the questionnaire and recommended an occupational consultation if necessary. During the consultation, a physician assessed if the lung cancer was work-related and, if it was, delivered a medical certificate to claim for compensation. Over 18 months, 440 patients received the self-administered questionnaire: 234 returned a completed questionnaire and a consultation was required for 120 patients. Compensation was judged possible for 41 patients. Among the 35 medical certificates delivered, 19 patients received compensation. Nearly half the patients (46%) were assessed as socially deprived and these patients took significantly longer to return the questionnaire compared with those who were not deprived. The mean cost of the process was €62.65 per patient. Our results showed a systematic self-administered questionnaire can be used to identify patients potentially exposed to carcinogens and to improve compensation.

[Treatment planning visit in oncology: factors predictive of satisfaction with the meeting with the physician and benefits of a second interview with a nurse]. / Annonce du projet thérapeutique en cancérologie. Facteurs influençant la réussite de l'entretien patient-médecin et intérêt d'un deuxième entretien non médical.

OBJECTIVE: Effective patient-physician communication is essential in life-threatening diseases. This is why a specific process, the so-called "diagnosis disclosure visit", is included in the management protocol for cancer patients. The distress engendered by the news may, however, hinder the information process. METHODS: We analyzed the emotional aspects of the consultation before informed consent to clinical trials in 140 patients with advanced cancer, to assess whether emotions interfered with information quality and to evaluate the potential benefit of a second interview with a nurse. Principal component analysis of responses to a self-completed questionnaire determined the satisfaction scores of interviews. Factors predictive of satisfaction were tested with a logistic regression model. RESULTS: Although most patients rated themselves as fully informed, 37% required additional information. Two variables were significantly correlated with success of the interview: a low depression score on the HADS scale (included in the questionnaire) and a feeling of inability to ask all questions. A second interview with the nurse increased patient satisfaction with the information from 63% to 95% on average. CONCLUSION: Cancer patients need information and do not always feel they have received it after speaking to the oncologist. They cannot always express their concerns, or may fear the answers to questions they therefore avoid asking. Depressed patients appear to find it more difficult to understand the information provided.

Molecular Characterization of Fluoroquinolone-Resistant Haemophilus parainfluenzae Clinical Isolates in Spain.

OBJECTIVE: The objective was to characterize a group of clinical isolates of fluoroquinolone-resistant Haemophilus parainfluenzae collected in Northern Spain (March-December 2014). METHODS: Twelve clinical isolates of H. parainfluenzae were studied by performing antimicrobial susceptibility testing and PCR amplification and nucleotide sequencing of the QRDR (quinolone resistance-determining region) of gyrA, parC, gyrB, and parE genes. Screening for plasmid-mediated quinolone resistance (PMQR) was also studied. Pulsed-field gel electrophoresis (PFGE) was used for molecular typing. RESULTS: Antimicrobial susceptibility testing showed that all the isolates were resistant to the fluoroquinolones tested (ciprofloxacin, levofloxacin, norfloxacin, and moxifloxacin). Analysis of the QRDR demonstrated that all the isolates presented mutations in gyrA and parC. A Glu88Lys substitution in ParC is reported for the first time in H. parainfluenzae. No PMQR gene was detected. PFGE results showed that isolates were not clonally related. CONCLUSION: Multiple H. parainfluenzae fluoroquinolone-resistant isolates grouped in the same area in a short period of time showed diverse substitutions in QRDR of gyrA/parC and were not clonally related, indicating individual emergence. In addition, we described the first report of Glu88Lys substitution in ParC.

Antimicrobial susceptibility, virulence potential and sequence types associated with Arcobacter strains recovered from human faeces.

PURPOSE: The genus Arcobacter includes bacteria that are considered emergent pathogens because they can produce infections in humans and animals. The most common symptoms are bloody and non-bloody persistent diarrhea but cases with abdominal cramps without diarrhea or asymptomatic cases have also been described as well as cases with bacteremia. The objective was to characterize Arcobacter clinical strains isolated from the faeces of patients from three Spanish hospitals. METHODOLOGY: We have characterized 28 clinical strains (27 of A. butzleri and one of A. cryaerophilus) isolated from faeces, analysing their epidemiological relationship using the multilocus sequence typing (MLST) approach and screening them for their antibiotic susceptibility and for the presence of virulence genes.Results/Key findings. Typing results showed that only one of the 28 identified sequence types (i.e. ST 2) was already present in the MLST database. The other 27 STs constituted new records because they included new alleles for five of the seven genes or new combinations of known alleles of the seven genes. All strains were positive for the ciaB virulence gene and sensitive to tetracycline. However, 7.4 % of the A. butzleri and A. cryaerophilus strains showed resistance to ciprofloxacin. CONCLUSION: The fact that epidemiological unrelated strains show the same ST indicates that other techniques with higher resolution should be developed to effectively recognize the infection source. Resistance to ciprofloxacin, one of the antibiotics recommended for the treatment of Arcobacter intestinal infections, demonstrated in 10.7 % of the strains, indicates the importance of selecting the most appropriate effective treatment.

[Clinical characteristics and outcome of infective endocarditis in individuals of the general population managed at a teaching hospital without cardiac surgery facilities. Study of 120 cases]. / Características clínicas y evolución de la endocarditis infecciosa en una población general no seleccionada, atendida en un hospital docente que no dispone de cirugía cardiaca. Estudio de 120 casos.

INTRODUCTION AND OBJECTIVES: To assess the clinical characteristics and management of infective endocarditis at a teaching hospital without cardiac surgery facilities. METHODS: Descriptive case-control study looking at trends. Risk factors, the occurrence of complications, the rate of referral for cardiac surgery, and the mortality rate were assessed. RESULTS: The study included 120 patients referred between 1990 and 2004, with a mean age of 50.8 (17.8) years (67.6% men). Disease incidence did not change throughout the study. Some 55% of infective endocarditis cases were from the ordinary general population, 25% were intravenous drug users, and 20% were of nosocomial origin. The number in the last category had increased over time. The most commonly isolated microorganism was Staphylococcus aureus. Around 83% of patients presented with a severe complication, with cardiac failure and septic metastasis being the most common. The in-hospital mortality rate was 19.2%. Acute renal failure (odds ratio 6.7, 95% confidence interval, 1.9-24) and perivalvular abscess (odds ratio 9.2, 95% confidence interval, 1.6-54) were independent predictors of death. The introduction in 2002 of a multidisciplinary infective endocarditis team, which included a consultant cardiac surgeon, was associated with a significant increase in referrals for surgery, from 14.5% to 34.5% (P=.03), though in-hospital mortality was not significantly altered, decreasing from 20.9% to 13.8% (P=.4). CONCLUSIONS: The occurrence of acute renal failure and perivalvular abscess worsen the prognosis of infective endocarditis. The introduction of a multidisciplinary infective endocarditis team altered management of the disease and increased referrals for cardiac surgery.

Conformal radiotherapy, reduced boost volume, hyperfractionated radiotherapy, and online quality control in standard-risk medulloblastoma without chemotherapy: results of the French M-SFOP 98 protocol.

PURPOSE: Between December 1998 and October 2001, patients <19 years old were treated for standard-risk medulloblastoma according to the Medulloblastome-Société Française d'Oncologie Pédiatrique 1998 (M-SFOP 98) protocol. Patients received hyperfractionated radiotherapy (36 Gy in 36 fractions) to the craniospinal axis, a boost with conformal therapy restricted to the tumor bed (to a total dose of 68 Gy in 68 fractions), and no chemotherapy. Records of craniospinal irradiation were reviewed before treatment start. RESULTS: A total of 48 patients were considered assessable. With a median follow-up of 45.7 months, the overall survival and progression-free survival rate at 3 years was 89% and 81%, respectively. Fourteen major deviations were detected and eight were corrected. No relapses occurred in the frontal region and none occurred in the posterior fossa outside the boost volume. Nine patients were available for volume calculation without reduction of the volume irradiated. We observed a reduction in the subtentorial volume irradiated to >60 Gy, but a slight increase in the volume irradiated to 40 Gy. No decrease in intelligence was observed in the 22 children tested during the first 2 years. CONCLUSION: This hyperfractionated radiotherapy protocol with a reduced boost volume and without chemotherapy was not associated with early relapses in children. Moreover, intellectual function seemed to be preserved. These results are promising.
