No full textPurpose: Thyroid malignancies can be treated by surgery followed by ablation of the remnant tissue with I-131. As iodide removal from the body occurs by renal extraction, in patients suffering from end-stage renal disease it is necessary to properly evaluate both timing and method of the extracorporeal treatment.
Methods: We present two patients on regular hemodialysis, admitted in isolation to the Nuclear Medicine Department and treated with I-131 for thyroid carcinoma diagnosed during the check-up for transplantation. Both patients underwent two hemodialysis sessions with a portable machine for CRRT (continuous renal replacement therapy), 24 and 48 hours after the administration of 50 mCi of I-131. The nursing staff were monitored with a dosimeter. Radioactivity of the patients, dialysate and urines were measured during hemodialysis.
Results: The greater reduction was obtained with the first dialysis, but in both patients a further, though shorter, hemodialysis at 48 hours was necessary for reaching a patient's radioactivity compatible with discharge. Radioactivity measured in the dialysate demonstrated the almost total removal of radioiodine by dialysis alone. In both patients, follow-up exams revealed a complete ablation of thyroid tissue, without signs of local recurrence. The dose of radioactivity of the dialysis staff was below allowable limits.
Conclusions: We conclude that a successful reduction of radioactivity, without dispersing its therapeutic efficacy, can be obtained with daily hemodialysis with a CRRT machine in patients in isolation treated with I-131. A therapeutic model is proposed
Diagnostic value of clinical examination of vascular access for haemosislysis vs ultrasound or fistulography.
No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Epidural steroids as a pharmacological approach
No full textCervicogenic headache is a relatively common pain syndrome related to functional and/or degenerative alterations of the cervical spine tract. Administration of steroid represents aw effective therapy for this headache, due to the anti-inflammatory effects combined with its direct analgesic effects on the C fibers. The epidural injection of steroids, while requesting skilled personnel for its execution, gh,es short term (2-month) pain relief with few risks or side effects. Moreover, epidural steroids allow reduction of analgesic drug consumption
Microsurgery and preventive haemostasis for autogenous radial-cephalic direct wrist access in adult patients with radial artery internal diameter below 1.6 mm
No full textBackground. Autogenous radial-cephalic direct wrist arteriovenous fistula (RCF), the gold standard for chronic dialysis, suffers from an elevated early failure rate (up to 20-50% with a pooled rate of 15.3%). Guidelines indicate that a small radial artery internal diameter ( 65 years was 64%, hypertension 96%, diabetes 32.1%, obesity (BMI > 30) 35%, vascular disease 46%. The mean distal radial artery and cephalic vein internal diameters, measured with ultrasound examination, were 1.3 mm and 1.9 mm, respectively. Seventy-five percent of the patients were not yet on dialysis treatment; 19% of whom had a previous failed vascular access created elsewhere without microsurgery. The remaining 25% patients were on dialysis treatment with a temporary femoral catheter. Results. All interventions ended with a patent anastomosis; no thrombosis occurred within the initial 24 h. The early failure rate was 14% (4 out of 28 patients). The causes of early failure were thrombosis > 1 week after surgery in one patient, lack of maturation (patent but unfunctional fistula) due to juxta-anastomotic vein stenosis in two patients and mid-vein stenosis in one patient. Treatment for all patients was proximalization of the anastomosis at the distal/mid forearm. Primary patency and secondary patency at 1 year were 68 +/- 10% and 96 +/- 5%, respectively. Conclusions. From our findings, we have shown that it is possible to create RCF in adult patients with a radial artery internal diameter of < 1.6 mm with an acceptable risk of early failure rate using microsurgery along with preventive haemostasis
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
