External beam radiotherapy(EBRT) is one of the principal curative treatments for patients with prostate cancer(PCa). Risk group classification is based on prostate-specific antigen(PSA) level, Gleason score, and T-stage. After risk group determination, the treatment volume and dose are defined and androgen deprivation therapy is prescribed, if appropriate. Traditionally, imaging has played only a minor role in T-staging due to the low diagnostic accuracy of conventional imaging strategies such as transrectal ultrasound, computed tomography, and morphologic magnetic resonance imaging(MRI). As a result, a notable percentage of tumours are understaged, leading to inappropriate and imprecise EBRT. The development of multiparametric MRI(mp MRI), an imaging technique that combines morphologic studies with functional diffusion-weighted sequences and dynamic contrastenhanced imaging, has revolutionized the diagnosis and management of PCa. As a result, mpM RI is now used in staging PCa prior to EBRT, with possible implications for both risk group classification and treatment decisionmaking for EBRT. mpM RI is also being used in salvageradiotherapy(SRT), the treatment of choice for patients who develop biochemical recurrence after radical prostatectomy. In the clinical context of biochemical relapse, it is essential to accurately determine the site of recurrence-pelvic(local, nodal, or bone) or distant-in order to select the optimal therapeutic management approach. Studies have demonstrated the value of mpM RI in detecting local recurrences-even in patients with low PSA levels(0.3-0.5 ng/m L)-and in diagnosing bone and nodal metastasis. The main objective of this review is to update the role of mpM RI prior to radical EBRT or SRT. We also consider future directions for the use and development of MRI in the field of radiation oncology.

Is it possible to stop nucleos(t)ide analogue treatment in chronic hepatitis B patients?

World Journal of Gastroenterology 2018年第17期24卷 1825-1838页

作者： elia Moreno-Cubero Robert T Sánchez del Arco Julia Pena-Asensio Eduardo Sanz de Villalobos Joaquín Míquel Juan Ramón Larrubia Translational Hepatology Unit Guadalajara University HospitalUniversity of AlcaláGuadalajara 19002Spain Internal Medicine Service Guadalajara University HospitalUniversity of AlcaláGuadalajara 19002Spain Department of Biology of Systems University of AlcaláAlcaláde Henares(Madrid)28805Spain Department of Medicine and Medical Specialties University of AlcaláAlcaláde Henares(Madrid)28805Spain

Chronic hepatitis B(CHB) remains a challenging global health problem, with nearly one million related deaths per year. Nucleos(t)ide analogue(NA) treatment suppresses viral replication but does not provide complete cure of the hepatitis B virus(HBV) infection. The accepted endpoint for therapy is the loss of hepatitis B surface antigen(HBs Ag), but this is hardly ever achieved. Therefore, indefinite treatment is usually required. Many different studies have evaluated NA therapy discontinuation after several years of NA treatment and before HBs Ag loss. The results have indicated that the majority of patients can remain off therapy, with some even reaching HBs Ag seroconversion. Fortunately, this strategy has proved to be safe, but it is essential to consider the risk of liver damage and other comorbidities and to ensure aclose follow-up of the candidates before considering this strategy. Unanswered questions remain, namely in which patients could this strategy be effective and what is the optimal time point at which to perform it. To solve this enigma, we should keep in mind that the outcome will ultimately depend on the equilibrium between HBV and the host's immune system. Viral parameters that have been described as good predictors of response in HBe Ag(+) cases, have proven useless in HBe Ag(-) ones. Since antiviral immunity plays an essential role in the control of HBV infection, we sought to review and explain potential immunological biomarkers to predict safe NA discontinuation in both groups.

Segmental arterial mediolysis, reparative phase: An analysis and case report showing conversion to fibromuscular dysplasia with renal infarction

引用

World Journal of Cardiovascular Diseases 2014年第2期4卷 50-60页

作者： Richard E. Slavin Julian del cerro Gonzalez Jose Manuel Machin Angel Robles Rita Maria Regojo Marie Luisa Diez Department of Internal Medicine La Paz University Hospital Madrid Spain Department of Internal Medicine University Hospital Guadalajara Spain Department of Pathology Legacy Emanuel Hospital Portland Oregon USA Department of Pathology University Hospital Guadalajara Spain Family Practice Physician Guadalajara Health Center Cervantes Branch Guadalajara Spain Interventional Radiologist University Hospital Guadalajara Spain

Segmental arterial mediolysis (SAM), an uncommon arteriopathy putatively caused by norepinephrine released by alpha-1 adrenergic agonists or some Beta-2 agonists capable of releasing norepinephrine from the peripheral sympathetic nervous system potentially can present ischemic and organ injury symptoms caused by sequelae created in its reparative phase in lieu of catastrophic hemorrhages announced in its injurious phase. The case documents this presentation—the patient presenting renal infarcts and ischemic lesions causing abdominal angina, hypertension and a nephrectomy event developing 10 years after prolonged ritodrine treatment for premature labor. This agent may have directly caused SAM or sensitized the patient to agonists causing SAM encountered at a latter date. A variety of lesions derived from injurious phase arterial injuries characterize reparative phase SAM. All were encountered in a hilar branch of the resected renal artery. These included side-by-side sequela aneurysms grossly forming a large fusiform aneurysm, granulation tissue filling adventitial medial tear spaces in which a dissecting hematomas developed, medial muscle loss centered to the outer media repaired with fibrous tissue, arterial stenosis created by reparative intimal plaques, and arterial thrombo-embolism. These lesions were mirrored in accompanying radiologic studies. The accompanying renal vein exhibited changes consistent with repair of the spastic venous angiopathy that often accompanies abdominal SAM. This angiopathy, putatively induced by Endothelin-1, suggested that this agent played a role in the genesis of the arterial lesions. Angiographic resolution of non-treated sequelae occurred in 5 months either spontaneously or due to treatment with bosentem. Conclusions: The histologic and angiographic changes demonstrate that the clinical onset of reparative SAM may be significantly delayed to produce ischemic lesions, renal infarction and in this case report, medial fibromuscular dy
