The European multicenter cohort study on cyanoacrylate embolization of refluxing great saphenous veins
2014
ObjectiveCyanoacrylate (CA) embolization of refluxing great saphenous veins (GSVs) has been previously described. The outcomes from a multicenter study are still lacking.MethodsA prospective multicenter study was conducted in seven centers in four European countries to abolish GSV reflux by endovenous CA embolization. Neither tumescent anesthesia nor postinterventional compression stockings were used. Varicose tributaries remained untreated until at least 3 months after the index treatment. Clinical examination, quality of life assessment, and duplex ultrasound evaluation were performed at 2 days and after 1, 3, 6, and 12 months.ResultsIn 70 patients, of whom 68 (97.1%) were available for 1…
Prognostic value of balance performance for improvements of community ambulation among stroke patients: a cohort study
2022
Background Despite the positive impact of improving the level of community ambulation among stroke patients, little prognostic research has focused on this indicator. Aim To investigate the prognostic value of the side-by-side, semi-tandem, and tandem standing balance positions and the five-sit-stand (5STS) test for discriminating patients undergoing physical rehabilitation who improve level of functional ambulation and predicting transition time. Design A cohort study with assessments repeated monthly until discharge for classifying patients in a community ambulation class. Setting A neurological rehabilitation unit of a hospital in Spain. Population A consecutive sample of 109 stroke pati…
Effects of sclerosing agents on head and neck hemangiomas : a systematic review
2019
Background The aim of this study was to systematically review the literature for studies that investigated the effects of sclerosing agents on head and neck hemangiomas. Material and methods Clinical trials, cohort studies, and descriptive studies were considered eligible and selected in a two-phase process. Six main electronic databases, in addition to three grey literature databases, were searched. Risk of bias (RoB) was assessed using the "Meta-Analysis of Statistics Assessment and Review Instrument" checklist. From fifty-six considered eligible, five were finally included. Results One article were judged at low, one at moderate, and three at high RoB. The sclerosing agents investigated …
Retrospective clinical evaluation of root canal treatment with or without photodynamic therapy for necrotic teeth and teeth subjected to retreatment.
2021
PURPOSE To compare the effect of photodynamic therapy (PDT) as a procedure to complement root canal treatment (RCT), for both primary treatment and retreatment. METHODS This was a retrospective study based on analysis of clinical records. A total of 214 teeth that had undergone RCT on either a primary or retreatment basis, with or without complementary PDT, were evaluated. For 118 teeth that met the previously established inclusion criteria, the time until healing was evaluated. Complementarily, the need for application of calcium hydroxide (CaHy) between visits and the number of visits necessary for completing the treatment were assessed. Data were analyzed using the Mann-Whitney and χ2 te…
A multicenter cohort study to compare quality of life in breast cancer patients according to sentinel lymph node biopsy or axillary lymph node dissec…
2009
Background: This prospective multicenter study assessed and compared the impact of different surgical procedures on quality of life (QoL) in breast cancer patients. Patients and methods: The EORTC QLQ-C30 and the EORTC QLQ-BR-23 questionnaires were used to assess global health status (GHS), arm (BRAS) and breast (BRBS) symptom scales, before surgery, just after surgery and 6 and 12 months later. The Kruskal–Wallis test with the Bonferroni correction was used to compare scores. A mixed model analysis of variance for repeated measurements was then applied to assess the longitudinal effect of surgical modalities on QoL. Results: Before surgery, GHS (P = 0.7807) and BRAS (P = 0.7688) QoL scores…
Hemithyroidectomy versus total thyroidectomy in the intermediate-risk differentiated thyroid cancer: the Italian Societies of Endocrine Surgeons and …
2021
The surgical treatment of the intermediate-risk DTC (1–4 cm) remains still controversial. We analyzed the current practice in Italy regarding the surgical management of intermediate-risk unilateral DTC to evaluate risk factors for recurrence and to identify a group of patients to whom propose a total thyroidectomy (TT) vs. hemithyroidectomy (HT). Among 1896 patients operated for thyroid cancer between January 2017 and December 2019, we evaluated 564 (29.7%) patients with unilateral intermediate-risk DTC (1–4 cm) without contralateral nodular lesions on the preoperative exams, chronic autoimmune thyroiditis, familiarity or radiance exposure. Data were collected retrospectively from the clini…
Thrombolytic therapy for submassive pulmonary embolism.
2012
Approximately 10% of all patients with acute pulmonary embolism (PE) die within the first three months after diagnosis. However, PE is not universally life-threatening, but covers a wide spectrum of clinical severity and death risk. Thrombolytic treatment is indicated patients with acute massive PE who are at high risk for early death, i.e. those patients who present with arterial hypotension and shock. On the other hand, low molecular-weight heparin or fondaparinux is adequate treatment for most normotensive patients with PE. Recombinant tissue plasminogen activator, given as 100 mg infusion over 2 h, is the treatment of choice for patients with PE, although older regimens using urokinase …
An International, Multicenter Retrospective Observational Study to Assess Technical Success and Clinical Outcomes of Patients Treated with an Endovas…
2022
Introduction: Type III endoleaks post-endovascular aortic aneurysm repair (EVAR) warrant treatment because they increase pressure within the aneurysm sac leading to increased rupture risk. The treatment may be difficult with regular endovascular devices. Endovascular aneurysm sealing (EVAS) might provide a treatment option for type III endoleaks, especially if located near the flow divider. This study aims to analyze clinical outcomes of EVAS for type III endoleaks after EVAR. Methods: This is an international, retrospective, observational cohort study including data from 8 European institutions. Results: A total of 20 patients were identified of which 80% had a type IIIb endoleak and the r…
Importance of Residual Renal Function in Continuous Ambulatory Peritoneal Dialysis: Its Influence on Different Parameters of Renal Replacement Treatm…
1999
<i>Objective:</i> To study the influence of residual renal function (RRF) on different parameters of the renal substitutive treatment offered by peritoneal dialysis. <i>Methods:</i> We analyzed the impact of RRF on dialysis dose, nutrition parameters, anemia and phosphocalcic metabolism in 37 patients with end-stage renal disease (ESRD) treated by continuous ambulatory peritoneal dialysis (CAPD). Analytical controls were done every 6 months after an initial assessment at the end of the first month of treatment. Multiple lineal regression models were used as the statistical method to analyze the influence of RRF on different theoretically dependent factors. RRF was ca…
Similarly increased congenital anomaly rates after intrauterine insemination and IVF technologies: a retrospective cohort study
2012
International audience; BACKGROUND: While intrauterine insemination (IUI), a simple, inexpensive and non-invasive technique, is the most used assisted reproduction technology (ART) worldwide, the risk of major birth defects following IUI is paradoxically not well documented. METHODS: Retrospective cohort study performed in Burgundy, France, over a 9-year period which consisted of the cross analysis of two prospective databases, the Burgundy perinatal network database and the database of the assisted conception units in Burgundy. A total of 1348 ART singletons [in vitro fertilization technologies (IVFT): n= 903; IUI: n= 445] matched with 4044 infants conceived naturally, 552 ART twins (IVFT:…
