The case of a white-heroin addict who developed disseminated candidiasis following coinfection byCandida glabrata andCandida albicans is reported. Genomic random amplified polymorphic DNA typing suggested that theCandida glabrata blood isolates originated in the oral cavity of the patient. This case strengthens the evidence thatCandida species other thanCandida albicans can be involved in the pathogenesis of disseminated candidiasis in heroin addicts. 相似文献

To evaluate the impact of an influenza vaccination (IV) coverage (IVC) in a vaccination campaign of an Emergency Department (EDVC) and its impact on ED time interval quality indicators. We conducted a 4 year observational study, with an intervention during the 4th year. IVC was calculated during pre-and early-epidemic periods. During the final period, a 12 weeks EDVC was implemented. Physicians and nurses were trained and sensitized in the importance of vaccination, and their role in the prevention of severe forms of influenza was reinforced. The vaccine was proposed by physicians and nurses, and delivered by them. Repeated measures ANOVA is a validated method for related not independent groups (https://statistics.laerd.com/statistical-guides/repeated-measures-anova-statistical-guide.php). Overall, IVC was 987/3191 (30.9%) with an increasing trend from 28.8 to 33.2%. In the fourth period, out of 868 patients identified with IV indication, 288 had already been vaccinated (IVC?33.2%). After excluding patients presenting criteria of exclusion, IV was proposed to 475 patients: 317 (66.7%) accepted. The vaccination rate after patient’s acceptance was 89.6% (288/317). At the end of the EDVC, influenza vaccination coverage was 572 (284?+?288)/868 (65.9%). The delay between arrival at the ED and seeing the triage nurse and physician as well as the overall ED length of stay were not modified during the study period and before and during EDVC. EDVC effectively doubled the influenza vaccination coverage, without modifying ED time interval quality indicators. 相似文献

Endocrine disorders seen in antiphospholipid syndrome are rare. To date, these disorders have generally involved Addison's disease. Recently reports have appeared of a few cases of primary or secondary hypopituitarism associated with primary antiphospholipid syndrome. We report the case of a young female patient who presented neuroendocrine symptoms during the postpartum period associated with an antiphospholipid syndrome. Hormone assessment showed complete anterior hypopituitarism and antiphospholipid antibodies were positive. We discuss the clinical, biological and radiological features observed in our patient and compare results with cases reported in the literature. This case illustrates the importance of screening for antiphospholipid syndrome in the etiological work-up of hypopituitarism associated with a history of recurrent thrombosis. 相似文献

The discovery of the interesting intrinsic properties of graphene, a two‐dimensional nanomaterial, has boosted further research and development for various types of applications from electronics to biomedicine. During the last decade, graphene and several graphene‐derived materials, such as graphene oxide, carbon nanotubes, activated charcoal composite, fluorinated graphenes and three‐dimensional graphene foams, have been extensively explored as components of biosensors or theranostics, or to remotely control cell–substrate interfaces, because of their remarkable electro‐conductivity. To date, despite the intensive progress in human stem cell research, only a few attempts to use carbon nanotechnology in the stem cell field have been reported. Interestingly, most of the recent in vitro studies indicate that graphene‐based nanomaterials (i.e. mainly graphene, graphene oxide and carbon nanotubes) promote stem cell adhesion, growth, expansion and differentiation. Although cell viability in vitro is not affected, their potential nanocytoxicity (i.e. nanocompatibility and consequences of uncontrolled nanobiodegradability) in a clinical setting using humans remains unknown. Therefore, rigorous internationally standardized clinical studies in humans that would aim to assess their nanotoxicology are requested. In this paper we report and discuss the recent and pertinent findings about graphene and derivatives as valuable nanomaterials for stem cell research (i.e. culture, maintenance and differentiation) and tissue engineering, as well as for regenerative, translational and personalized medicine (e.g. bone reconstruction, neural regeneration). Also, from scarce nanotoxicological data, we also highlight the importance of functionalizing graphene‐based nanomaterials to minimize the cytotoxic effects, as well as other critical safety parameters that remain important to take into consideration when developing nanobionanomaterials.

In the Horn of Africa, there is a high prevalence of tuberculosis that is reported to be partly driven by multidrug-resistant (MDR) Mycobacterium tuberculosis strictu sensu strains. We conducted a prospective study to investigate M. tuberculosis complex species causing tuberculosis in Djibouti, and their in vitro susceptibility to standard anti-tuberculous antibiotics in addition to clofazimine, minocycline, chloramphenicol and sulfadiazine. Among the 118 mycobacteria isolates from 118 successive patients with suspected pulmonary tuberculosis, 111 strains of M. tuberculosis, five Mycobacterium canettii, one ‘Mycobacterium simulans’ and one Mycobacterium kansasii were identified. Drug-susceptibility tests performed on the first 78 isolates yielded nine MDR M. tuberculosis isolates. All isolates were fully susceptible to clofazimine, minocycline and chloramphenicol, and 75 of 78 isolates were susceptible to sulfadiazine. In the Horn of Africa, patients with confirmed pulmonary tuberculosis caused by an in vitro susceptible strain may benefit from anti-leprosy drugs, sulfamides and phenicol antibiotics. 相似文献

This report is an overview of enterovirus (EV) detection in Tunisian polio-suspected paralytic cases (acute flaccid paralysis (AFP) cases), healthy contacts and patients with primary immunodeficiencies (PID) during an 11-year period. A total of 2735 clinical samples were analyzed for EV isolation and type identification, according to the recommended protocols of the World Health Organization. Three poliovirus (PV) serotypes and 28 different nonpolio enteroviruses (NPEVs) were detected. The NPEV detection rate was 4.3%, 2.8% and 12.4% in AFP cases, healthy contacts and PID patients, respectively. The predominant species was EV-B, and the circulation of viruses from species EV-A was noted since 2011. All PVs detected were of Sabin origin. The PV detection rate was higher in PID patients compared to AFP cases and contacts (6.8%, 1.5% and 1.3% respectively). PV2 was not detected since 2015. Using nucleotide sequencing of the entire VP1 region, 61 strains were characterized as Sabin-like. Among them, six strains of types 1 and 3 PV were identified as pre-vaccine-derived polioviruses (VDPVs). Five type 2 PV, four strains belonging to type 1 PV and two strains belonging to type 3 PV, were classified as iVDPVs. The data presented provide a comprehensive picture of EVs circulating in Tunisia over an 11-year period, reveal changes in their epidemiology as compared to previous studies and highlight the need to set up a warning system to avoid unnoticed PVs. 相似文献

BackgroundChondrocalcinosis is a metabolic arthropathy rarely affecting the anterior chest wall (ACW).Aim of the workTo report here a case of a polyarticular chondrocalcinosis with an uncommon localization in the sternoclavicular joints (SCJs), revealed by computed tomography (CT).Case reportA 76-year old female presented to the Rheumatology outpatient clinic Kassab orthopedics institute with low back pain. The history goes back to 4 months prior to her presentation when she developed mechanical back pain that progressively worsened during the last month, becoming inflammatory with prolonged morning stiffness. She had no history of fever or weight loss and no symptoms in the cervical spine, shoulders, chest wall, hips or knees. Physical examination revealed limited range of motion of hips, cervical and lumbar spine and bilateral swelling of SCJs without tenderness on pressure or mobilization. Biochemical investigations showed normal levels of inflammatory markers, phosphorus and calcium. Conventional radiographs showed multiple areas of calcification in the intra-vertebral discs, joint space narrowing of sacroiliac (SI) and coxofemoral joints. Chest wall radiograph appeared normal. ACW and pelvic CT were done to further delineate the cause. It showed intra-cartilaginous bilateral calcifications of SCJs, sacroilliac, intervertebral discs, coxofemoral joints and pubic symphysis. The final diagnosis was polyarticular chondrocalcinosis. The patient received analgesics, non-steroidal anti-inflammatory drugs and had functional rehabilitation sessions. Conclusion: This case points to the rare localization of chondrocalcinosis in the SCJ and should be considered especially in an elderly female. Early recognition is necessary in order to initiate an appropriate and prompt treatment. 相似文献
