RESUMO
BACKGROUND: Histoplasmosis caused by Histoplasma capsulatum var. duboisii (Hcd) is a rare, but probably underestimated, endemic infection described in intertropical Africa. Therefore, the epidemiology of the infection remains unclear, and there is no consensus on therapeutic management. METHODS: Using a comprehensive search on different Internet databases, we collected case reports of Hcd infection published from 1993 to 2019. Epidemiological and clinical charts and therapeutic strategies were analyzed. RESULTS: We found 94 well-documented cases of Hcd infection, and 30.1% of the patients were under 18 years old. Symptoms occurred in some patients several decades after leaving the endemic area. Cutaneous/subcutaneous lesions, bone infections, and lymphadenopathies, both isolated and combined, were the most frequent presentations. The human immunodeficiency virus (HIV) coinfection rate was at 20.8%, with fever, lymphadenopathies, and an absence of bone infection being the differentiating elements from patients living without HIV. The rate of disseminated forms (60.6% in our review) significantly increased as compared to studies published before 1993, but without correlation with HIV infection. The global mortality rate was at 23.4% by the end of follow-up. The outcome was not correlated with the antifungal drug prescribed, nor with HIV serologic status, but was correlated with the initiation of an antifungal therapy. CONCLUSIONS: Hcd histoplasmosis is a severe fungal infection for which the precise mode of acquisition remains to be determined. There is a need for affordable and more specific diagnostic tools. Itraconazole and amphotericin B are the best therapeutic alternatives and should be available in all low-income countries of the endemic area.

To evaluate the in vitro susceptibility of Fusarium to isavuconazole, 75 clinical isolates were identified using matrix-assisted laser desorption ionization-time of flight mass spectrometry and then tested with a broth microdilution method (EUCAST) and the gradient concentration strip (GCS) technique. The activity of isavuconazole overall was shown to be limited, with an MIC50 of >16 µg/ml, without significant differences between the species complexes. The categorical agreement between GCS and EUCAST was 97.4% to 100%, making the GCS as a valuable alternative.

Reference methods used to assess the drug susceptibilities of Aspergillus fumigatus isolates consisted of EUCAST and CLSI standardized broth microdilution techniques. Considering the increasing rate and the potential impact on the clinical outcome of azole resistance in A. fumigatus, more suitable techniques for routine testing are needed. The gradient concentration strip (GCS) method has been favorably evaluated for yeast testing. The aim of this study was to compare the CGS test with EUCAST broth microdilution for amphotericin B (AMB), posaconazole (PCZ), itraconazole (ITZ), voriconazole (VRZ), and isavuconazole (ISA). A total of 121 Aspergillus section Fumigati strains were collected, including 24 A. fumigatus sensu stricto strains that were resistant to at least one azole drug. MICs were determined using GCS and EUCAST methods. Essential agreement between the 2 methods was considered when MICs fell within ±1 dilution or ±2 dilutions of the 2-fold dilution scale. Categorical agreement was defined as the percentage of strains classified in the same category (susceptible, intermediate, or resistant) with both methods. Essential agreements with ±1 dilution and ±2 dilutions were 96.7, 93.4, 90.0, 89.3, and 95% and 100, 99.2, 100, 97.5, and 100% for AMB, PCZ, ITZ, VRZ, and ISA, respectively. Categorical agreements were 94.3, 86.1, 89.3, and 88.5% for AMB, PCZ, ITZ, and VRZ, respectively. Detection of resistance was missed with the GCS for one strain (4.1%) for PCZ and for 2 strains (8.3%) for ISA. Determination of ITZ MICs using the GCS allowed the detection of 91.7% of azole-resistant strains. The GCS test appears to be a valuable method for screening azole-resistant A. fumigatus clinical isolates.

Urogenital schistosomiasis (UGS) remains common in sub-Saharan African migrants. The aim of the study was to describe UGS cases detected among patients attending primary healthcare consultations in free outpatient clinics in Paris. This retrospective cohort study included all cases of active UGS from 2004 to 2017. Cases were defined by the presence of Schistosoma haematobium typical ova at urine microscopy. Primary care physicians prescribed it on the basis of epidemiological or clinical criteria. Demographic, clinical, biological, and imaging data were retrieved. Active UGS was diagnosed in 105 cases. The sex ratio (F/M) was 3/102 with a median age of 25. Most cases came from West Africa and recently arrived in Europe (median delay, 1 year). Patients under 18 (23%) were more frequent after 2011. Compatible symptoms were reported in 63/104 patients (60%), hematuria being the most frequent (43/104). Urine dipstick detected micro-hematuria in 42/60 patients screened (70%). In 73 cases, urine microscopy was performed from either one, two, or three micturitions on separate days. The rate of positive urine microscopy increased from one (69.2%) to two micturitions (95.4%). All patients except three received praziquantel. Among those who underwent ultrasonography, 30/86 (35%) had abnormalities, 28/30 at the bladder. A step-by-step clinical assessment led to the detection of active UGS: questions on age, location in childhood and hematuria, physical examination, and urine dipstick. A prospective study in primary care is needed for protocol-based management of active UGS to be part of a socio-medical program for migrants.

Biofilm in endoscopes is a major problem that can result in failure of disinfection. We studied the survival of K. pneumoniae in a biofilm formed on endoscope tubes subjected to combined chemical and physical stresses. We monitored bacterial survival in the biofilm after the action of 1% and 2% GTA either immediately or after 15 days of desiccation and described the ability of surviving bacteria to recolonize endoscope tubing in a dynamic model. There were surviving bacteria after 5-min exposure to 2% and 1% GTA. The percentage of survivors after 2% and 1% GTA was greater when the GTA treatment was performed after 15 days of prior desiccation of the biofilm. The survivors were able to recolonize and reform biofilm on abiotic surfaces probably because of the survival of persisters in a viable but non-culturable state in the biofilm. Our findings emphasize that the current guidelines on endoscope reprocessing should be strictly followed but that once constituted the biofilm in endoscope tubing will be very difficult to eradicate with present practices.

OBJECTIVE: To analyze the content of two official French-speaking websites that are used to inform the general public about recommended vaccines in France and Quebec. STUDY DESIGN: Qualitative content analysis. METHODS: All pages that inform and educate parents regarding childhood vaccination were downloaded and analyzed according to evidence-informed risk communication metrics. RESULTS: A total of 32 webpages, 14 videos, and two infographics were included in the analysis. The following were the most frequent risk communication approaches: 'debunking common misconceptions about vaccination' or 'answering common questions about vaccines.' Harm and benefit information focused primarily on the risks of vaccine-preventable diseases and the risks of adverse events after immunization. Most materials used qualitative terminology to describe the risk (e.g., vaccines are among the safest tools, adverse events are rare). Very few materials provided numeric likelihood of harms and benefits. When numeric information was stated, they were only presenting the risks of the diseases or number of cases in an outbreak. The approaches used to debunk misconceptions generally focused on the myth itself rather than the correct information. Few materials used visual aids (e.g., graphics, pictures, icons arrays, etc.) to convey important information. CONCLUSIONS: It is often assumed that misinformation and rumors about vaccination found online is a leading cause of the increase in vaccine hesitancy. Existing communication materials could be improved to better align with best practices in risk communication. Given the availability of confusing and conflicting vaccine narratives, it is crucial that authoritative communication materials aim to build trust and support informed choices about vaccination.

INTRODUCTION: Sarcopenia evaluated from the measurement of skeletal muscle index (SMI) has been evaluated as a predictive factor of morbidity and mortality after surgery. The objective of this study was to evaluate whether it was predictive of morbidity and mortality in patients managed by cystectomy or tri-modality therapy (TMT), combining radiotherapy and chemotherapy after endoscopic resection of the tumour, for localized muscle-invasive bladder cancer. MATERIALS AND METHODS: In all, 146 consecutive patients from 2 university hospital centres treated by cystectomy between January 2012 and April 2017 or TMT between October 2008 and October 2014 were included. The SMI was measured on axial computed-tomography at the level of the transverse process of L3, before treatment. Sarcopenia was assessed in two ways: either by SMI without muscle mass adjustment or according to the definition by Martin and al. based on gender and patient BMI, then called "adjusted sarcopenia". The primary endpoint was overall survival (OS) for sarcopenia. The secondary endpoints were OS, progression-free survival (PFS) and survival without re-admission (SRH) for the total population and for each treatment group. Survival analyses were performed using the Cox model. The association between sarcopenia and complications has been investigated by the Chi2 test. RESULTS: The characteristics of sarcopenic (n=67) and non-sarcopenic (n=79) patients were comparable except for 2 criteria: older patients in the sarcopenic group and a higher proportion of neo-adjuvant chemotherapy in non-sarcopenic patients. Sarcopenia was not significantly associated with any type of survival. Sarcopenia was not associated with the proportion or severity of complications. CONCLUSION: Unlike unadjusted SMI, sarcopenia was not associated with survival or complications. LEVEL OF EVIDENCE: 3.

AIM: Overtreatment is an actual problem in low risk localized prostate cancer (PC) management. Active surveillance (AS) is a solution to limit this problem, but eligibility criteria remained discussed. The aim was to assess possibilities of widening selection criteria for patient in AS, studying curative treatment free survival (CTFS) according to restricted or expanded eligibility criteria. METHODS: We retrospectively studied patients beginning AS between 2008 and 2014, for Gleason 6 localized PC, PSA<15ng/ml,Assuntos

RESUMO
OBJECTIVE: The aim of the Cancerology Committee of the French Association of urology (CCAFU) is to propose an update of the guidelines in the management of hormone-sensitive metastatic prostate cancer. METHODS: A systematic review (Medline) of the literature from 2018 to 2020 was conducted by the CCAFU Findings. Several patterns can be defined at this stage depending on prognostic, metastatic volume, and whether metastases are synchronous or metachronous. Androgenic deprivation therapy (ADT) remains the mainstay of treatment at the metastatic stage. Docetaxel in combination with ADT improves overall survival in synchronous metastatic prostate cancer. In this situation, the combination of ADT with abiraterone is also a standard of care regardless of tumor volume. Recent data have led to the recommendation that ADT should be used in conjunction with a new generation hormone therapy (Apalutamide or Enzalutamide) in metastatic synchronous or metachronous patients, regardless of tumour volume. Local treatment of prostate cancer with radiotherapy improves survival in synchronous oligometastatic patients. Metastases-directed therapy is being evaluated. CONCLUSION: This update of the French recommendations should help improve the management of patients with prostate cancer.

OBJECTIVE: - The purpose of the guidelines national committee ccAFU was to propose updated french guidelines for prostate cancer. METHODS: - A Medline search was achieved between 2018 and 2020, as regards diagnosis, options of treatment and follow-up of prostate cancer (PCA), and to evaluate the different references specifying their levels of evidence. RESULTS: - The guidelines outline the genetics, epidemiology and diagnosis of prostate cancer, as well as the concepts of screening and early detection. MRI, the gold standard imaging test for localized cancer, is indicated before prostate biopsies are performed. The therapeutic methods are detailed and indicated according to the clinical situation. Active surveillance is a reference therapeutic option for low-risk tumours with a low evolutionary risk. Early salvage radiotherapy is indicated in case of biological recurrence after radical prostatectomy. Androgen deprivation therapy (ADT) remains the backbone therapy in the metastatic stage. Docetaxel in combination with ADT improves overall first-line survival in synchronous metastatic prostate cancer. In this situation, the combination of ADT with abiraterone is also a standard of care regardless of tumor volume. Recent data indicate that ADT should be indicated with a new generation of hormone therapy (Apalutamide or Enzalutamide) in metastatic synchronous or metachronous patients, regardless of tumour volume. Local treatment of prostate cancer with radiotherapy improves survival in synchronous oligometastatic patients. Targeted treatment of metastases is being evaluated. In patients with castration-resistant prostate cancer (CRPC), new therapies that have emerged in recent years help to better control tumor progression and improve survival. CONCLUSION: - These updated french guidelines will contribute to increase the level of urological care for the diagnosis and treatment for prostate cancer.

Multimodal regimens consist en more than one treatment to treat localized prostate cancer. They are now proposed routinely for high-risk diseases. Different approaches could be defined: In conclusion, multimodal regimens increase the risk of side effects compared to surgery or radiotherapy alone. Indications of these approaches muste be discussed with the patients after a careful evaluation of the benefit/risk ratio.

Aspergillus section Terrei is a species complex currently comprised of 14 cryptic species whose prevalence in clinical samples as well as antifungal susceptibility are poorly known. The aims of this study were to investigate A. Terrei clinical isolates at the species level and to perform antifungal susceptibility analyses by reference and commercial methods. Eighty-two clinical A. Terrei isolates were collected from 8 French university hospitals. Molecular identification was performed by sequencing parts of beta-tubulin and calmodulin genes. MICs or minimum effective concentrations (MECs) were determined for 8 antifungal drugs using both EUCAST broth microdilution (BMD) methods and concentration gradient strips (CGS). Among the 79 A. Terrei isolates, A. terreus stricto sensu (n = 61), A. citrinoterreus (n = 13), A. hortai (n = 3), and A. alabamensis (n = 2) were identified. All strains had MICs of ≥1 mg/liter for amphotericin B, except for two isolates (both A. hortai) that had MICs of 0.25 mg/liter. Four A. terreus isolates were resistant to at least one azole drug, including one with pan-azole resistance, yet no mutation in the CYP51A gene was found. All strains had low MECs for the three echinocandins. The essential agreements (EAs) between BMD and CGS were >90%, except for those of amphotericin B (79.7%) and itraconazole (73.4%). Isolates belonging to the A section Terrei identified in clinical samples show wider species diversity beyond the known A. terreus sensu stricto Azole resistance inside the section Terrei is uncommon and is not related to CYP51A mutations here. Finally, CGS is an interesting alternative for routine antifungal susceptibility testing.

Cryptococcal antigen (CryAg) testing in serum and CSF is a clue diagnostic tool for cryptococcosis. In this study, we reviewed the performances of the CryAg detection (Premier EIA, Meridian) routinely performed in broncho-alveolar lavage fluid (BALF) during a 7-year period (2007-2013). CryAg was detected in 12 cases among 4650 BALF analyzed, while positive culture from BALF was detected in nine cases. We found sensitivity, specificity, positive and negative predictive values at 0.44-0.80 (according to the radio-clinical form), 0.99, 0.36, and 0.99, respectively. These results do not support the routine use of the test in BALF.

OBJECTIVE: To describe malaria during pregnancy outside endemic areas. MATERIALS AND METHODS: We retrospectively reviewed all cases of imported malaria during pregnancy, diagnosed over a 11-year period in a French hospital. RESULTS AND CONCLUSION: We recovered 18 cases, all from sub-Saharan countries. The infection could appear distantly from arrival in France (up to 36 months), was asymptomatic in 3 cases, with anemia being the most common marker of infection (n = 14). The adverse consequences for the fetus (n = 3) or the newborn (n = 4) were frequent. Physicians should be aware of these atypical presentations in order to anticipate the diagnosis and improve the maternal and fetal prognosis.

BACKGROUND: Primary cutaneous B-cell lymphomas represent approximately 25% of primary cutaneous lymphomas. Follicular centre cell lymphomas (PCFCL) and marginal zone lymphomas (PCMZL) are the two histological subtypes that present an indolent evolution. Radiotherapy is one of the recommended treatment options with few series reported. OBJECTIVE: This study aimed to evaluate radiotherapy outcomes in term of overall survival (OS) and disease-free survival (DFS) for patients suffering from a PCMZL or PCFCL, to search for predictive factors of recurrence, and to evaluate chronic and aesthetics adverse events and patient's satisfaction. METHODS: Patients treated with contact low energy radiotherapy for a PMZCL or PCFCL from April 2009 to June 2017 in Saint Louis hospital were retrospectively analysed. Total dose ranged from 18 to 30 Gy. Objective response (OR) rates, DFS and OS as patterns of recurrence according to radiation fields were analysed. Univariate analysis of DFS has been performed according to clinical and biological parameters. Acute toxicity, long-term adverse events and satisfaction were collected via individualized questionnaires. RESULTS: Forty-six patients were included. Median follow-up was 43.5 months. OR was achieved for 100% of cases. Recurrence occurred in 39% of cases. Median DFS was 44 months. Three-year DFS and 5-year DFS were 56% and 51%, respectively. OS at 3 and 5 year was 100%. Only sex was significantly associated with DFS. Acute AEs occurred in 48% of cases without grade 3 and 4. 55% reported some moderate aesthetic sequelae for long-term AEs. 97% were satisfied with treatment. CONCLUSION: This study confirms the good risk-benefit of radiotherapy for the treatment of primary cutaneous indolent B-cell lymphomas due to the high response rate and a long DFS. No significant factor for recurrence was identified, except female sex. Long-term aesthetic evaluation was good or excellent for most of the patients.

OBJECTIVE: The purpose of the guidelines national committee ccAFU was to propose updated French guidelines for prostate cancer. METHODS: A Medline search was achieved between 2016 and 2018, as regards diagnosis, options of treatment and follow-up of prostate cancer, and to evaluate the different references specifying their levels of evidence. RESULTS: Epidemiology, classification, staging systems, diagnostic evaluation of prostate cancer are reported. Disease management options are detailed. Recommandations are reported according to the different clinical situations. Active surveillance is a major option in low risk PCa. Radical prostatectomy remains a standard of care of localized PCa. The three-dimensional conformal radiotherapy is the technical standard. A dose of≥76Gy is recommended. Moderate hypofractionation provides short-term biochemical control comparable to conventional fractionation. In case of intermediate risk PCa, radiotherapy can be combined with short-term androgen deprivation therapy (ADT). In case of high-risk disease, long-term ADT remains the standard of care. ADT is the backbone therapy of metastatic disease. In men with metastases at first presentation, upfront chemotherapy combined with ADT should be considered as a standard. In this situation, the combination of ADT and abiraterone acetate also becomes a new standard. In case of metastatic castration-resistant PCa (mCRPC), new hormonal treatments and chemotherapy provide a better control of tumor progression and increase survival. CONCLUSION: These updated French guidelines will contribute to increase the level of urological care for the diagnosis and treatment for prostate cancer.
RESUMO
BACKGROUND: Outcome of intermediate risk rectal cancer may be improved by the addition of oxaliplatin during 5-fluoruracil concomitant neoadjuvant chemoradiotherapy. The purpose of this study is to analyze the main clinical results of the ACCORD12 trial (NCT00227747) in rectal cancer after 5 years of follow-up. PATIENTS AND METHODS: Inclusion criteria were as follows: rectal adenocarcinoma accessible to digital examination staged T3-T4 Nx M0 (or T2 Nx distal anterior rectum). Two neoadjuvant chemoradiotherapy regimens were randomized: CAP45 (RT 45 Gy + capecitabine) and CAPOX50 (RT 50 Gy + capecitabine and oxaliplatin). Main end point was sterilization of the operative specimen. Acute and late toxicities were prospectively analyzed with dedicated questionnaires. RESULTS: Between November 2005 and July 2008, 598 patients were included in the trial. After a median follow-up of 60.2 months, there was no difference between treatment arms in multivariate analysis either for disease-free survival or overall survival (OS) [P = 0.9, hazard ratio (HR)=1.02; 95% confidence interval (CI), 0.76-1.36 and P = 0.3, HR = 0.87; 95% CI, 0.66-1.15, respectively]. There was also no difference of local control in univariate analysis (P = 0.7, HR = 0.92; 95% CI, 0.51-1.66). Late toxicities were acceptable with 1.6% G3 anal incontinence, and <1% G3 diarrhea, G3 rectal bleeding, G3 stenosis, G3-4 pain, G3 urinary incontinence, G3 urinary retention and G3 skeletal toxicity. There was a slight increase of erectile dysfunction over time with a 63% rate of erectile dysfunction at 5 years. There was no significant statistical difference for these toxicities between treatment arms. CONCLUSIONS: The CAPOX50 regimen did not improve local control, disease-free survival and overall survival in the ACCORD12 trial. Late toxicities did not differ between treatment arms.

Until now, there has been no consensus on the best method for the detection of anti-Aspergillus antibodies, a key diagnostic tool for chronic aspergilloses. To better appreciate the usage of and confidence in these techniques, the Société Française de Mycologie Médicale (French Society for Medical Mycology; SFMM) performed a two-step survey of French experts. First, we administered an initial survey to French labs performing Aspergillus serology to depict usage of the different techniques available for Aspergillus serology. Second, an opinion poll was conducted of 40 experts via an online questionnaire. Each item was rated from 1 to 9 according to the level of agreement. The initial survey revealed that enzyme-linked immunosorbent assay (ELISA) (81%) and immunoelectrophoresis (IEP) (67%) were the most commonly used techniques for screening and confirmation, respectively. The distinction between screening and confirmation techniques was confirmed by the experts (median = 7) with a 44.2% variation coefficient. Only ELISA for screening and IEP and Western blot (WB) for confirmation were clearly considered valuable methods (median ≥8 with variation coefficients less than 30%). The use of a confirmation technique was recommended in the case of a positive result in a compatible clinical context (cystic fibrosis, for example) or during the patient's follow-up. In the case of discordant results between the screening and confirmation techniques, the experts recommended greater confidence in the results obtained with the confirmation technique. All experts emphasized the need to standardize Aspergillus serology techniques and to better define the place of each of them in the diagnosis of aspergillosis.

BACKGROUND: The prevalence of the Histoplasma capsulatum var. capsulatum (Hcc) histoplasmosis may be underestimated West Africa, both because the diagnosis is not mentioned in the early stages of the disease and due to limited biological resources available. CASE REPORT: We report a case of disseminated histoplasmosis due to Hcc in a Senegalese HIV patient. The diagnosis was suspected following the demonstration of small encapsulated yeasts within neutrophils on a thin blood smear. It was further confirmed using a specific real-time PCR applied on a DNA specimen extracted from the thin blood smear. CONCLUSION: To the best of our knowledge, this is the first case of Hcc infection diagnosed in Senegal. Blood smear may be a valuable screening tool in the case of bloodstream dissemination and can be used for further molecular approaches to confirm the diagnosis.
