RESUMO

BACKGROUND: Previous studies have observed an increased incidence of Cetuximab-induced hypersensitivity infusion reactions (CI-IRs) in the southeastern states of the USA. Tick's bites were suspected of generating cross-reactions between cetuximab and alpha-gal. This study aims was to describe the incidence and associated risk factors of CI-IRs, in the French areas chosen according to their Lyme disease incidence. PATIENTS AND METHODS: A retrospective chart review was conducted on patients that received cetuximab infusion from January 2010 to June 2019 in 4 French areas with different Lyme disease incidence rates. RESULTS: Of 1392 patients, 117 (8.4%) experienced a CI-IR, including 68 severe (grade 3 or 4) reactions (4.9%). This CI-IR incidence was significantly higher in the Lyme disease high-risk area than in the other areas (13.2% versus 7.1%, 8.1% and 6.4%; P = 0.016). Sex (P = 0.53), premedication (P = 0.91), primary cancer location (P = 0.46) and chemotherapy regimen type (P = 0.78) had no impact on CI-IR incidence in the overall population. In the head and neck squamous cell carcinoma (HNSCC) patient subgroup, CI-IRs were significantly more frequent in the high-risk area (16.4% versus 6.7%, 7.1% and 7.0%; P = 0.0015). CONCLUSION: This study suggests that patients treated in the French area with the highest incidence of Lyme disease are at a higher risk of CI-IRs.

RESUMO

INTRODUCTION: This pilot study evaluated the imaging performance of pretargeted immunological positron emission tomography (immuno-PET) using an anti-carcinoembryonic antigen (CEA) recombinant bispecific monoclonal antibody (BsMAb), TF2 and the [68Ga]Ga-labelled HSG peptide, IMP288, in patients with metastatic colorectal carcinoma (CRC). PATIENTS AND METHODS: Patients requiring diagnostic workup of CRC metastases or in case of elevated CEA for surveillance were prospectively studied. They had to present with elevated CEA serum titre or positive CEA tumour staining by immunohistochemistry of a previous biopsy or surgical specimen. All patients underwent endoscopic ultrasound (EUS), chest-abdominal-pelvic computed tomography (CT), abdominal magnetic resonance imaging (MRI) and positron emission tomography using [18F]fluorodeoxyglucose (FDG-PET). For immuno-PET, patients received intravenously 120 nmol of TF2 followed 30 h later by 150 MBq of [68Ga]Ga-labelled IMP288, both I.V. The gold standard was histology and imaging after 6-month follow-up. RESULTS: Eleven patients were included. No adverse effects were reported after BsMAb and peptide injections. In a per-patient analysis, immuno-PET was positive in 9/11 patients. On a per-lesion analysis, 12 of 14 lesions were positive with immuno-PET. Median SUVmax, MTV and TLG were 7.65 [3.98-13.94, SD 3.37], 8.63 cm3 [1.98-46.64; SD 14.83] and 37.90 cm3 [8.07-127.5; SD 43.47] respectively for immuno-PET lesions. Based on a per-lesion analysis, the sensitivity, specificity, positive-predictive value and negative-predictive value were, respectively, 82%, 25%, 82% and 25% for the combination of EUS/CT/MRI; 76%, 67%, 87% and 33% for FDG-PET; and 88%, 100%, 100% and 67% for immuno-PET. Immuno-PET had an impact on management in 2 patients. CONCLUSION: This pilot study showed that pretargeted immuno-PET using anti-CEA/anti-IMP288 BsMAb and a [68Ga]Ga-labelled hapten was safe and feasible, with promising diagnostic performance. TRIAL REGISTRATION: ClinicalTrials.gov NCT02587247 Registered 27 October 2015.

RESUMO

Delayed defecation is common in patients on intensive care. We aimed to determine factors associated with time to defecation after admission to intensive care and in turn its association with length of stay and mortality. We studied 396 adults admitted to one of five intensive care units in whom at least 2 days' invasive ventilation was anticipated during an expected stay of at least 3 days. The median (IQR [range]) time to defecate by the 336 out of 396 (84%) patients who did so before intensive care discharge was 6 (4-8 [1-18]) days. Defecation was independently associated with five factors, hazard ratio (95%CI), higher values indicating more rapid defecation: alcoholism, 1.32 (1.05-1.66), p = 0.02; laxatives before admission, 2.35 (1.79-3.07), p < 0.001; non-invasive ventilation, 0.54 (0.36-0.82), p = 0.004; duration of ventilation, 0.78 (0.74-0.82), p < 0.001; laxatives after admission, 1.67 (1.23-2.26), p < 0.001; and enteral nutrition within 48 h of admission, 1.43 (1.07-1.90), p = 0.01. Delayed defecation was associated with prolonged intensive care stay but not mortality.

RESUMO

OBJECTIVE: The innate immune system plays a central role in osteoarthritis (OA). We identified 14-3-3ε as a novel mediator that guides chondrocytes toward an inflammatory phenotype. 14-3-3ε shares common characteristics with alarmins. These endogenous molecules, released into extracellular media, are increasingly incriminated in sustaining OA inflammation. Alarmins bind mainly to toll-like receptor 2 (TLR2) and TLR4 receptors and polarize macrophages in the synovium. We investigated the effects of 14-3-3ε in joint cells and tissues and its interactions with TLRs to define it as a new alarmin involved in OA. DESIGN: Chondrocyte, synoviocyte and macrophage cultures from murine or OA human samples were treated with 14-3-3ε. To inhibit TLR2/4 in chondrocytes, blocking antibodies were used. Moreover, chondrocytes and bone marrow macrophage (BMM) cultures from knockout (KO) TLRs mice were stimulated with 14-3-3ε. Gene expression and release of inflammatory mediators [interleukin 6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor alpha (TNFα)] were evaluated via reverse transcription quantitative polymerase chain reaction (RT-qPCR) and ELISA. RESULTS: In vitro, 14-3-3ε induced gene expression and release of IL6 and MCP1 in the treated cells. The inflammatory effects of 14-3-3ε were significantly reduced following TLRs inhibition or in TLRs KO chondrocytes and BMM. CONCLUSIONS: 14-3-3ε is able to induce an inflammatory phenotype in synoviocytes, macrophages and chondrocytes in addition to polarizing macrophages. These effects seem to involve TLR2 or TLR4 to trigger innate immunity. Our results designate 14-3-3ε as a novel alarmin in OA and as a new target either for therapeutic and/or prognostic purposes.

RESUMO

BACKGROUND: The aim of our study was to evaluate the diversity, or homogeneity, of recommendations made in multidisciplinary team meetings (MTM) concerning the management of facial skin cancers in France, and to analyze the determinants thereof. PATIENTS AND METHODS: We contacted a panel of dermatology and ENT multidisciplinary teams (MDT) and collected their recommendations made at meetings regarding 3 clinical cases: squamous cell carcinoma in a renal transplant patient with an incomplete excision margin (case 1), locally advanced basal cell carcinoma (case 2), and lentigo maligna (case 3). The responses were analyzed globally and then based on 2 subgroups defined by the presence or absence of a dermatologist in the MTM. The effect of the makeup of the MTM (based on the presence of a dermatologist, a plastic surgeon, an oncologist and an ENT specialist) was evaluated for the main therapeutic proposals. RESULTS: The opinions of the 45 MDMs that responded to the survey were mixed for the three cases as regards important elements such as the indication of surgical revision for case 1, the proposal of an alternative treatment to surgery for case 2, and monitoring arrangements for case 3. Certain proposals were associated with the presence of a dermatologist in the MTM, such as discussion of adaptation of immunosuppressive treatment and details of the surgical margins to be applied for case 1, as well as simple monitoring and details of monitoring arrangements in case 3. CONCLUSION: It is important to maintain dermatologists in MTMs on account of their expertise in all therapeutic areas concerning skin cancers.

RESUMO

OBJECTIVE: To investigate the safety profile of percutaneous cryoablation of renal tumours < 7 cm, utilising data extracted from an international multicentre registry. MATERIALS AND METHODS: A retrospective review of all immediate and delayed complications from a multicentre database was performed and was categorised according to the Clavien-Dindo classification. Statistical analysis was performed for both overall complications (all Clavien-Dindo) and major complications (Clavien-Dindo 3 to 5). The following criteria were identified as potential predictive factors for complications: centre number, modality of image guidance, tumour size (≤ 4 cm vs. > 4 cm), number of tumours treated in the same session (1 vs. > 1) and tumour histology. RESULTS: A total of 713 renal tumours underwent ablation in 647 individual sessions. In 596 of the cases, one tumour was treated; in the remaining 51 cases, several tumours were treated per session. Mean lesion size was 2.8 cm. Fifty-four complications (Clavien-Dindo 1 to 5) occurred as a result of the 647 procedures, corresponding to an overall complication rate of 8.3%. The most frequent complication was bleeding (3.2%), with 9 cases (1.4%) requiring subsequent treatment. The rate of major complication was 3.4%. The only statistically significant prognostic factor for a major complication was a tumour size > 4 cm. CONCLUSION: Percutaneous renal cryoablation is associated with a low rate of complications. Tumours measuring more than 4 cm are associated with a higher risk of major complications. KEY POINTS: • Percutaneous kidney cryoablation has a low rate of complications. • Bleeding is the most frequent complication. • A tumour size superior to 4 cm is a predictive factor of major complication.

RESUMO

The objective of this cross-sectional survey was to assess the prevalence of psychoactive substance use (PSU) in people attending 11 French Sexual Transmitted Infection Centers, and to specify their profiles (PSU and link with risky sexual behaviors) using the ascending hierarchical clustering method. Among the 5220 individuals who completed the survey, 55.6% were men and the median age was 24 years [IQR: 20-31]. Among the participants, 2751 (52.7%) reported PSU at least once in their life. Ascending hierarchical clustering identified seven distinct profiles of participants based on their PSU. This study shows a high prevalence of PSU and alcohol consumption in this young population. Moreover, subgroup analysis allowed identifying groups of psychoactive substance users who presented specific risks or vulnerabilities and who should be priority targets for interventions, particularly sexual minority groups.

RESUMO

AIM: We explored the associations between childhood exposure to screens, including televisions, computers, game consoles, tablets and smartphones and primary language disorders. METHODS: This multi-centre case-control study comprised 167 children aged 3.5-6.5 years, who were born in 2010-2012 and diagnosed with primary language disorders, and 109 matched controls without language disorders. Questionnaires were completed by their parents who were recruited by 16 family doctors and 27 speech and language therapists in the Ille-et-Vilaine region of France. The data were analysed using a multivariate logistic regression model and presented as adjusted odds ratios (aOR) and 95% confidence intervals (95% CI). RESULTS: We found that cases (44.3%) and controls (22.0%) exposed to screens in the morning before nursery or primary school were three times more likely to develop primary language disorders (aOR 3.40, 95% CI 1.60-7.23). When this risk was combined with rarely or never discussing screen content with their parents (aOR 2.14, 95% CI 1.01-4.54) they were six times more likely to have language problems (aOR 5.86, 95% CI 1.44-23.95). CONCLUSION: Being exposed to screens in the morning before school, and rarely or never discussing screen content with parents, meant children were six times more likely to develop primary language disorders.

RESUMO

OBJECTIVE: Natural history of paediatric-onset ulcerative proctitis (UP) is poorly described. Our aim was to describe the phenotype and disease course of incident UP in a population-based study of paediatric-onset UC. PATIENTS AND METHODS: All patients with UC diagnosed <17 years from 1988 to 2004, and followed during >2 years have been extracted from a population-based registry. UC location was defined according to the Paris classification. Cumulative risks for use of immunosuppressants (IS), anti-tumour necrosis factor alpha (TNF-α) therapy, colonic extension and colectomy were described using Kaplan-Meier method. Risk factors for colonic extension were assessed using Cox proportional hazards models. RESULTS: 158 patients with paediatric-onset UC (91 females) with a median age at diagnosis of 14.5 years (Q1: 11.4-Q3: 16.1) have been identified and followed during a median of 11.4 years (8.2-15.8). Among them, 25% had UP (E1) at diagnosis and 49% of them presented a colonic extension at maximal follow-up. In these children, the cumulative risk for colonic extension was 10% at 1 year, 45% at 5 years and 52% at 10 years. No parameter at diagnosis was associated with colonic extension in the UP (E1 group). IS use was significantly lower in patients with UP than in those with E2, E3 or E4 location (p=0.049). For the UP cohort, the cumulative risk for colectomy was 3% at 1 year, 10% at 5 years, 13% at 10 years and 13% at 15 years. Risks for colonic extension, treatment with anti-TNF-α and colectomy did not differ between the E1 group and the E2-E3-E4 group. CONCLUSIONS: UP is frequent in paediatric-onset UC and should not be considered as a minor disease. Compared with more extensive UC locations, risks for colonic extension, anti-TNF-α therapy and colectomy were similar in UP, whereas the risk for use of IM was lower.

RESUMO

Inflammatory bowel disease and periodontitis are both described as a disproportionate mucosal inflammatory response to a microbial environment in susceptible patients. Moreover, these two conditions share major environmental and lifestyle-related risk factors. Despite this intriguing pathogenic parallel, large-scale studies and basic research have only recently considered periodontal outcomes as relevant data. There are mounting and consistent arguments, from recent epidemiologic studies and animal models, that these two conditions might be related. This article is a comprehensive and critical up-to-date review of the current evidence and future prospects in understanding the biologic and epidemiologic relationships between periodontal status and inflammatory bowel disease.

RESUMO

BACKGROUND: The number of dermatologists in Brittany is currently decreasing (-4.5% from 2010 to 2014) while waiting times for medical appointments are increasing. Our objective was to evaluate the practice activities of dermatologists and to establish a 5-year demographic projection. METHODS: We conducted a cross-sectional survey in Brittany (France) from November 2014 to January 2015. We also interviewed dermatology residents (incoming years: 2010 to 2015), and collected information about their hometown and their career plans in 5years. RESULTS: Response rates were 98% for dermatologists and 100% for residents. Waiting times for appointments increased from 2010 to 2015 (P<0.01). Eighty-seven percent of dermatologists under 50 were women vs. 62% of dermatologists aged 50 and over (P<0.01). The proportion of dermatologists working fewer than 7 half-days per week was higher in women (33% vs. 13%, P=0.02). The number of retirements foreseen in 5years was 33 (52%) among the 63 dermatologists aged 55 and over. Among the 26 residents, 58% were planning to practice in Brittany and 42% were considering part-time work. We estimate that the number of newly graduated dermatologists exercising in Brittany in 5years will be 25. CONCLUSION: Our results suggest that the number of dermatologists will continue to decrease by 6% between 2015 and 2020.

RESUMO

INTRODUCTION: In June 2012, the government of Canada severely restricted the scope of the Interim Federal Health Program that had hitherto provided coverage for the health care needs of refugee claimants. The Quebec government decided to supplement coverage via the provincial health program. Despite this, we hypothesized that refugee claimant children in Montreal would continue to experience significant difficulties in accessing basic health care. OBJECTIVES: (1) Report the narrative experiences of refugee claimant families who were denied health care services in Montreal following June 2012, (2) describe the predominant barriers to accessing health care services and understanding their impact using thematic analysis and (3) derive concrete recommendations for child health care providers to improve access to care for refugee claimant children. METHODS: Eleven parents recruited from two sites in Montreal participated in semi-structured interviews designed to elicit a narrative account of their experiences seeking health care. Interviews were recorded, transcribed, coded using NVivo software and subjected to thematic analysis. RESULTS: Thematic analysis of the data revealed five themes concerning barriers to health care access: lack of continuous health coverage, health care administrators/providers' lack of understanding of Interim Federal Health Program coverage, refusal of services or fees charged, refugee claimants' lack of understanding about health care rights and services and language barriers, and four themes concerning the impact of denial of care episodes: potential for adverse health outcomes, psychological distress, financial burden and social stigma. CONCLUSION: We propose eight action points for advocacy by Canadian paediatricians to improve access to health care for refugee claimant children in their communities and institutions.

RESUMO

Cytomegalovirus (CMV) is the leading cause of congenital infection and non-genetic sensorineural hearing loss in children. There are no recent data on the incidence of CMV infection during pregnancy in Canada. This present study was undertaken to determine the seroprevalence of CMV IgG antibodies and the rate of seroconversion in a cohort of pregnant women in the province of Québec, Canada. We used serum samples and questionnaire data collected as part of the 3D Pregnancy and Birth Cohort Study (2010-2013) conducted in Québec, Canada. CMV IgG antibodies were determined in serum samples collected at the first and third trimesters. Associations between independent variables and seroprevalence were assessed using logistic regression, and associations with seroconversions, by Poisson regression. Of 1938 pregnant women tested, 40·4% were seropositive for CMV at baseline. Previous CMV infection was associated with: working as a daycare educator, lower education, lower income, having had children, first language other than French or English, and being born outside Canada or the United States. Of the 1122 initially seronegative women, 24 (2·1%) seroconverted between their first and third trimesters. The seroconversion rate was 1·4 [95% confidence interval (CI) 0·9-2·1]/10 000 person-days at risk or 3·9 (95% CI 2·5-5·9)/100 pregnancies (assuming a 280-day gestation). The high proportion of pregnant women susceptible to CMV infection (nearly 60%) and the subsequent rate of seroconversion are of concern.

RESUMO

During summer 2016, all the conditions for local mosquito-borne transmission of Zika virus (ZIKV) are met in mainland France: a competent vector, Aedes albopictus, a large number of travellers returning from ZIKV-affected areas, and an immunologically naive population. From 1 January to 15 July 2016, 625 persons with evidence of recent ZIKV infection were reported in mainland France. We describe the surveillance system in place and control measures implemented to reduce the risk of infection.

RESUMO

PURPOSE: To evaluate the therapeutic impact of (18)F-fluorocholine (FCH) PET/CT in biochemical recurrent prostate cancer (PC) and to investigate the value of quantitative FCH PET/CT parameters in predicting progression-free survival (PFS). METHODS: This retrospective study included 172 consecutive patients with PC who underwent FCH PET/CT for biochemical recurrence. Mean rising PSA was 10.7 ± 35.0 ng/ml. Patients with positive FCH PET were classified into three groups: those with uptake only in the prostatic bed, those with locoregional disease, and those with distant metastases. Referring physicians were asked to indicate the hypothetical therapeutic strategy with and without the FCH PET/CT results. Clinical variables and PET parameters including SUVmax, SUVpeak, SUVmean, total lesion choline kinase activity (TLCKA) and standardized added metabolic activity (SAM) were recorded and a multivariate analysis was performed to determine the factors independently predicting PFS. RESULTS: In 137 of the 172 patients, the FCH PET/CT scan was positive, and of these, 29.9 % (41/137) had prostatic recurrence, 42.3 % (58/137) had pelvic lymph node recurrence with or without prostatic recurrence, and 27.7 % (38/137) had distant metastases. The FCH PET/CT result led to a change in treatment plan in 43.6 % (75/172) of the 172 patients. Treatment was changed in 49.6 % (68/137) of those with a positive FCH PET/CT scan and in 20 % (7/35) of those with a negative FCH PET/CT scan. After a median follow-up of 29.3 months (95 % CI 18.9 - 45.9 months), according to multivariate analysis age <70 years, SAM ≥23 and SUVmean ≥3 were parameters independently predicting PFS. A nomogram constructed using the three parameters showed 49 months of PFS in patients with the best scores (0 or 1) and only 11 months in patients with a poor score (score 3). CONCLUSION: This study indicates that a positive FCH PET result in PC patients with biochemical recurrence predicts a shorter PFS and confirms the major impact of the FCH PET result on the management of biochemical recurrent PC.

RESUMO

A central element was first described in focal nodular hyperplasia (FNH) as a so-called "central scar," and is normally associated with this entity. However, many other liver masses may present with a central element. Depending on its appearance, and the lesion itself, central elements can be essential, helpful, or confusing for diagnosis. Indeed, nodules that develop on liver vascular disorders, fibrolamellar hepatocellular carcinoma, large hemangioma, peripheral cholangiocarcinoma, or epithelioid hemangioenthelioma often present with a central element, thus increasing the level of diagnostic confidence when present. On the other hand, central elements are rare or atypical in liver metastases, hepatocellular adenoma, or hepatocellular carcinoma. In this setting, the presence of a central element can lead to a misdiagnosis. The description and details of the imaging features of these different central elements, especially on MRI, as well as a thorough evaluation of the entire lesion, can improve the diagnostic performance in these cases.

RESUMO

In October 2014, an outbreak of 12 autochthonous chikungunya cases, 11 confirmed and 1 probable, was detected in a district of Montpellier, a town in the south of France colonised by the vector Aedes albopictus since 2010. A case returning from Cameroon living in the affected district was identified as the primary case. The epidemiological investigations and the repeated vector control treatments performed in the area and around places frequented by cases helped to contain the outbreak. In 2014, the chikungunya and dengue surveillance system in mainland France was challenged by numerous imported cases due to the chikungunya epidemic ongoing in the Caribbean Islands. This first significant outbreak of chikungunya in Europe since the 2007 Italian epidemic, however, was due to an East Central South African (ECSA) strain, imported by a traveller returning from West Africa. Important lessons were learned from this episode, which reminds us that the threat of a chikungunya epidemic in southern Europe is real.

RESUMO

This study of comments posted on major French print and TV media websites during the H1N1 epidemic illustrates the relationship between the traditional media and social media in responding to an emerging disease. A disturbing "geography of blame" was observed suggesting the metamorphosis of the folk-devil phenomenon to the Internet. We discovered a subterranean discourse about the putative origins and "objectives" of the H1N1 virus, which was absent from the discussions in mainstream television channels and large-circulation print media. These online rumours attributed hidden motives to governments, pharmaceutical companies, and figures of Otherness that were scapegoated in the social history of previous European epidemics, notably Freemasons and Jews.

RESUMO

BACKGROUND: In a context of resurgent syphilis in France since 2000, we conducted a retrospective study in two different centres in Montpellier, France: the dermatology department of a public hospital and an anonymous and free centre for provision of information, diagnosis and treatment of venereal diseases (CDAG-CIDDIST). PATIENTS AND METHODS: All patients with syphilis seen from January 2002 to December 2011 were included with the collaboration of the National Health Institute (InVS) and the Bacteriology Department of the public hospital. Epidemiology, clinical presentation, serological data, and treatment and monitoring data for up to 2 years were recorded. RESULTS: One hundred and seventy-five cases of syphilis were diagnosed: 154 at the CDAG and 21 at the dermatology unit. Ninety-six percent of cases concerned men with a median age of 36 years. Eighty-two percent of these cases involved men having sex with men (MSM). Forty-nine percent of cases were diagnosed in the secondary stage, 22% in the primary stage and 28% in the latent stage. The treatment administered in the majority of cases (73%) was benzathine-penicillin G. The numbers of patients showing incomplete follow-up were equal at both centres, with 31 patients (17.7%) failing to attend the follow-up visit. A decrease of at least 2 dilutions in VDRL score occurred in the year following treatment for 93 of 103 patients (90%). Patients managed at the dermatology department were older than their counterparts managed at the CDAG and exhibited more frequent cutaneous eruptions (58% vs. 3%, P<0.0001) but were less frequently bisexual. However, no significant differences were seen concerning sex and associated infections (hepatitis, gonococcal infection, HPV or herpes). DISCUSSION: Syphilis is on the rise, especially in the MSM population. The epidemiological characteristics of our cohort were consistent with those of other Western European countries. Although the reasons for consultation differed between CDAG/CIDDIST and the dermatology department, the two centres are complementary. Benzathine-penicillin G was the most commonly used treatment, in accordance with the recommendations. Measures must be introduced to improve patient monitoring without compromising anonymity.

RESUMO

SUMMARY A diphtheria outbreak occurred from February to November 2011 in the village of Kimba and its surrounding settlements, in Borno State, northeastern Nigeria. We conducted a retrospective outbreak investigation in Kimba village and the surrounding settlements to better describe the extent and clinical characteristics of this outbreak. Ninety-eight cases met the criteria of the case definition of diphtheria, 63 (64.3%) of whom were children aged <10 years; 98% of cases had never been immunized against diphtheria. None of the 98 cases received diphtheria antitoxin, penicillin, or erythromycin during their illness. The overall case-fatality ratio was 21.4%, and was highest in children aged 0-4 years (42.9%). Low rates of immunization, delayed clinical recognition of diphtheria and absence of treatment with antitoxin and appropriate antibiotics contributed to this epidemic and its severity.
