喉癌的手术治疗已有一百余年历史,1860年即有报告全喉切除治疗喉梅毒,并在1873年开始用于治疗喉癌。全喉切除术治疗喉癌虽然效果良好,但术后不能经喉发声和用鼻呼吸,患者甚感痛苦,为此,有些患者拒绝手术治疗。近30年来,由于对喉的胚胎学、解剖学及喉癌扩散方式的深入研究,发现喉癌早期尚局限于喉的一个解剖区时,很少向其他解剖区扩展。随着喉癌防治知识普及临床确诊的早期病例增多,由于诊断技术与  相似文献

This is a new method for the determination of creatine kinase isoenzyme MB activity in serum. The method uses direct activity measurement of creatine kinase B subunit activity after blocking of CK-M subunit activity by inhibiting antibodies. The test takes no longer than 15 min. The method yields an intra-serial C.V. of 2.0-12.9%, and a C.V. from day to day of 5.5%. The detection limit is 3.4 U/l creatine kinase MB. In the 95 cases with proven myocardial infarction several types of creatine kinase MB activity kinetics could be determined. The percentage of creatine kinase MB of peak CK-total is 6-25%, with a mean of 11.1%. The amount of creatine kinase MB with respect to total CK activity after reinfarction is higher than the amount after initial infarction.  相似文献

Molecular characterization of virulence and antimicrobial resistance profiles were determined for Shigella species isolated from children with diarrhea in Fortaleza, Brazil. Fecal specimens were collected along with socioeconomic and clinical data from children with moderate to severe diarrhea requiring emergency care. Shigella spp. were isolated by standard microbiological techniques, and we developed 4 multiplex polymerase chain reaction assays to detect 16 virulence-related genes (VRGs). Antimicrobial susceptibility tests were performed using disk diffusion assays. S. flexneri and S. sonnei were the predominant serogroups. S. flexneri was associated with low monthly incomes; more severe disease; higher number of VRGs; and presence of pic, set, and sepA genes. The SepA gene was associated with more intense abdominal pain. S. flexneri was correlated with resistance to ampicillin and chloramphenicol, whereas S. sonnei was associated with resistance to azithromycin. Strains harboring higher numbers of VRGs were associated with resistance to more antimicrobials. We highlight the correlation between presence of S. flexneri and sepA, and increased virulence and suggest a link to socioeconomic change in northeastern Brazil. Additionally, antimicrobial resistance was associated with serogroup specificity in Shigella spp. and increased bacterial VRGs.  相似文献

Biofilm-related disease   总被引:2,自引:0,他引:2  
Introduction: Biofilm formation represents a protected mode of growth that renders bacterial cells less susceptible to antimicrobials and to killing by host immune effector mechanisms and so enables the pathogens to survive in hostile environments and also to disperse and colonize new niches. Biofilm disease includes device-related infections, chronic infections in the absence of a foreign body, and even malfunction of medical devices.

Areas covered: This review puts forward a new medical entity that represents a major public health issue, which we have named ‘biofilm-related disease’. We highlight the characteristics of biofilm disease including its pathogenesis, microbiological features, clinical presentation, and treatment challenges.

Expert commentary: The diversity of biofilm-associated infections is increasing over time and its impact may be underestimated. This peculiar form of development endows associated bacteria with a high tolerance to conventional antimicrobial agents. A small percentage of persister cells developing within the biofilm is known to be highly tolerant to antibiotics and has typically been involved in causing relapse of infections. Knowledge of the pivotal role played by biofilm-growing microorganisms in related infections will provide new treatment dynamics for this biofilm-related disease.  相似文献

Osteochondritis dissecans is a rare condition and often involves the medial femoral condyle. We are here reporting two uncommon localizations in children involving the lateral portion of the tibial plateau in one and the patella in the other. They were two fourteen-year-old boys with respectively 4 and 3 months history of a right knee pain and locking. No previous trauma had been noted. X-ray studies and MR images provided definitive diagnosis. However, in the tibial localization, osteochondritis was associated to a damaged lateral discoid menisci and in the patellar localization, the osteochondral fragment was detached in the joint. Regularization of the lateral menisci and removal of a loose body were respectively performed under arthroscopy in the two knees. Literature is reviewed with an emphasis particularly on pathogenesis of these rare localizations.  相似文献

Introduction: Peripheral T-cell lymphoma (PTCL) is a relatively rare, heterogeneous group of mature T-cell neoplasms generally associated with poor prognosis, partly because of refractoriness against conventional cytotoxic chemotherapies. To improve the outcome of patients with PTCL, the clinical development of several novel agents is currently under investigation.

Areas covered: Since the first approval of pralatrexate (dihydrofolate reductase inhibitor) by the US Food and Drug Administration, belinostat, romidepsin (histone deacetylase inhibitors), and brentuximab vedotin (anti-CD30 antibody-drug conjugate) have been approved in the US, and many other countries. In addition, mogamulizumab (anti-CC chemokine receptor 4 antibody), chidamide (histone deacetylase inhibitor), and forodesine (purine nucleoside phosphorylase inhibitor) have been approved in Asian countries, including China, and Japan. In this review, we have summarized the available data regarding these approved agents and new agents currently under development for PTCL.

Expert opinion: Novel agents will be a promising therapeutic option in selected patients with relapsed/refractory PTCL and will change the daily clinical practice in the treatment of PTCL. However, these are not a curative option when used as a single agent. Further clinical developments are expected, comprising 1) combination therapies of new agents with cytotoxic chemotherapies; 2) ‘novel-novel’ combinations; 3) immune therapies, including chimeric antigen receptor T-cell therapy; and 4) predictive marker analysis.  相似文献

Zusammenfassung Hintergrund und Ziel:   Partizipative Entscheidungsfindung (Shared Decision-Making) gewinnt als Modell der Arzt-Patienten-Beziehung auch im deutschen Gesundheitssystem zunehmend an Bedeutung. Insbesondere im Bereich chronischer Erkrankungen erwartet man sich von diesem Konzept mittel- bis langfristige Verbesserungen der Behandlungsergebnisse. Bislang liegen der deutschen Versorgungsforschung jedoch kaum empirische Daten zum Stand und zu den Entwicklungstendenzen der partizipativen Entscheidungsfindung vor. Diese Studie liefert aktuelle Ergebnisse zu dieser Fragestellung aus einer deutschlandweiten Befragung von terminal niereninsuffizienten Patienten. Methodik:   Im Rahmen des Programms Qualität in der Nephrologie (QiN) wurden in einer schriftlichen, deutschlandweiten Erhebung 6 614 Patienten mit terminaler Niereninsuffizienz befragt. Der Fragebogen enthielt ein zuvor übersetztes und validiertes Instrument zur Erfassung der wahrgenommenen Einbeziehung in die Therapie (PICS). Ergebnisse:   82% der Befragten fühlen sich durch ihre Ärzte für eine Beteiligung an Entscheidungen motiviert. 81% der Patienten informieren sich aktiv bei ihren Ärzten über ihre Erkrankung und Behandlungsmöglichkeiten. 69% geben an, dass eine gemeinsame Entscheidungsfindung von Arzt und Patient stattgefunden hat. Das Lebensalter, die Dialysejahre und das Geschlecht stehen im Zusammenhang mit der wahrgenommenen Einbeziehung. Schlussfolgerung:   Dieser Aufsatz bietet eine valide Grundlage für die prospektive Erforschung der partizipativen Entscheidungsfindung in der Behandlung der terminalen Niereninsuffizienz. Die Ergebnisse der vorliegenden Studie deuten auf eine hohe Bereitschaft von Dialysepatienten hin, sich aktiv am Prozess der Entscheidungsfindung zu beteiligen. Spezifische Patientencharakteristika und die Präferenzen der Patienten sollten nicht nur bei der alltäglichen klinischen Interaktion mit den Patienten Berücksichtigung finden. Sie könnten darüber hinaus im Rahmen der Qualitätssicherung systematisch erfasst und als Verbesserungspotential genutzt werden.und ärztliche Leiter der teilnehmenden KfH-Nierenzentrenkooperierende Nierenzentren (4.

The aim of this study was to increase the understanding of caring from a transcultural perspective and to develop the first outline of a theory. The theoretical perspective includes Eriksson's theory of caritative caring. Texts on caring by the transcultural theorists, including Campinha-Bacote, Kim-Godwin, Leininger and Ray, are analysed using content analysis. The overall theme that resulted from this analysis was that caring is a complex whole. Three main categories of caring emerged: inner caring, outer caring and the goal of caring. Inner caring consists of caring is a relationship, and caring and culture are seen in different dimensions. Outer caring refers to caring affected by educational, administrative and social and other structures. The goal of caring consists of caring leading to change towards health and well-being. The main categories include categories and subcategories that are compared with Eriksson's theory of caritative caring.
A model for intercultural caring is generated abductively. Caring and culture appear in three dimensions: caring as ontology independent of context; caring as a phenomenon emphasised differently in different cultures; caring as nursing care activities is unique. Caring alleviates suffering and leads to health and well-being. This model describes caring from an intercultural perspective as a mutual but asymmetric relationship between the nurse and the patient, including the patient's family and community. The patient's cultural background and acculturation influence caring. The cultural background, cultural competence and organisation of the nurse also influence caring. Caring is seen as a complex whole. This study integrates Campinha-Bacote's, Kim-Godwin's, Leininger's and Ray's views of caring with Eriksson's caritative caring and presents caring from a transcultural perspective in a new way as a model for intercultural caring, which can benefit nursing care, education, research and administration.  相似文献
