Imperative and Elective Indications for Nephron-Sparing Surgery for Renal Tumors: Long-Term Oncological Follow-Up
2010
INTRODUCTION: Nephron-sparing surgery (NSS) is mandatory for patients with renal tumors in both kidneys or in a solitary kidney in order to preserve renal function (imperative indication). NSS has also become the gold standard (elective indication) for small unilateral renal tumors (< 4 cm) with a normal contralateral kidney. We report the oncological long-term follow-up of NSS of our own series and discuss the results of the current literature. PATIENTS AND METHODS: From 1979 until 2006, a total of 851 patients was treated at our institu-tion by NSS. The mean tumor diameter was 3 cm (0.5-11 cm) for elective cases and 4.2 cm (1.2-11 cm) for imperative cases. The median follow-up for electiv…
Rare Cancers Europe (RCE) methodological recommendations for clinical studies in rare cancers: A European consensus position paper
2015
While they account for one-fifth of new cancer cases, rare cancers are difficult to study. A higher than average degree of uncertainty should be accommodated for clinical as well as for population-based decision making. Rules of rational decision making in conditions of uncertainty should be rigorously followed and would need widely informative clinical trials. In principle, any piece of new evidence would need to be exploited in rare cancers. Methodologies to explicitly weigh and combine all the available evidence should be refined, and the Bayesian logic can be instrumental to this end. Likewise, Bayesian-design trials may help optimize the low number of patients liable to be enrolled in …
Positioning of the cross-stitch on the modified Kessler core tendon suture
2018
[EN] Cryopreserved human tendons were sutured with different variations of a modified Kessler-type grasping suture in a series of different designs in order to assess the influence of the distance between the cross-stitch on the core suture (5 and 10 mm from the cut tendon edge) on the peripheral suture. An original mathematical model was employed to explain the mechanical behavior (strength, deformation, and distribution of load) of the different suture designs. The effect of the peripheral epitendinous suture, combined with the distance of the core suture, was evaluated. The variation of core suture distance had no relevant consequences on the overall resilience of the design. However, in…
Alpha-adrenergic drugs in retrograde ejaculation.
1974
6 men with complete or partial loss of ejaculation as a result of retroperitoneal lymphadenectomy (performed because of testicular tumor) were treated with an intravenous injection of 60 mg synephrine. Synephrine stimulates adrenergic alpha-receptors. Only 1 man with sustained retrograde ejaculation improved following treatment showing antegrade ejaculation. This temporary restoration of fertility was thought to be due to an increase in bladder neck tone and prevention of backflow of semen into the bladder as a result of stimulation of adrenergic alpha-receptors.
Vulnerabilità posizionale e intersezionale. I minori migranti soli come caso paradigmatico
2020
A partire dalla definizione teorica della vulnerabilità come posizione, il contributo prende in considerazione come paradigmatica le condizione che si producono per i minori migranti soli lungo il viaggio come durante la permanenza in Italia. Particolare attenzione viene dedicata alle procedure della richiesta di asilo come ambito di vittimizzazione secondaria, e all'ineffettività dei principi posti a tutela dei minori alla luce del nuovo corso della politica italiana.
AISF position paper on liver transplantation and pregnancy: Women in Hepatology Group, Italian Association for the Study of the Liver (AISF)
2016
After the first successful pregnancy in a liver transplant recipient in 1978, much evidence has accumulated on the course, outcomes and management strategies of pregnancy following liver transplantation. Generally, liver transplantation restores sexual function and fertility as early as a few months after transplant. Considering that one third of all liver transplant recipients are women, that approximately one-third of them are of reproductive age (18-49 years), and that 15% of female liver transplant recipients are paediatric patients who have a >70% probability of reaching reproductive age, the issue of pregnancy after liver transplantation is rather relevant, and obstetricians, paedi…
Patient safety in dentistry : dental care risk management plan
2010
Objectives: Although the safety of patients has been one of the inherent concerns of dental practice, but because the proposals made in the field of dentistry are few and improperly structured, this paper constitutes an attempt to present a proposal titled "Plan for Dental Health Care Risk Management," promoted by the General Council of Dentists of Spain, including a description of the proposed work methodology. Design: The "risk management plan" proposed in this paper is based on applying the basic concepts dealt with in patient safety to the field of dentistry, due to the fact that the available bibliography contains no specific "health care risk management plan" for dentistry specificall…
Dépistage du cancer du sein : en route vers le futur
2016
Breast cancer remains a potentially lethal disease, which requires aggressive treatments and is associated with long-term consequences. Its prognosis is linked to both tumor biology and burden at diagnosis. Although treatments have allowed important improvements in prognosis over the past 20 years, breast cancer screening remains necessary. Mammographic screening allows earlier stage diagnoses and a decrease of breast cancer specific mortality. However, breast cancer screening modalities should be revised with the objective to address demonstrated limitations of mammographic screening (limited benefit, imperfect sensitivity and specificity, overdiagnoses, radiation-induced morbidity). Furth…
Investigating the Performance of Enhanced Permeable Groins in Series
2020
The enhanced permeable groin is a novel eco-friendly and cost-effective technique for bank protection and restoration of meander bends. The behavior of bed deformations due to the distance between the structures has to be studied to design enhanced permeable groins in series properly. In this study, scour morphologies around enhanced permeable groins in series, characterized by four different distances and located in a 180°
Comparative Study of the Initial Experience in Performing Robotic and Laparoscopic Right Hepatectomy with Technical Description of the Robotic Techni…
2017
<b><i>Background:</i></b> Despite potential benefits of robotic liver surgery, it is still considered a “development in progress” technique. <b><i>Methods:</i></b> The outcomes of 14 patients undergoing robotic right hepatectomy were analyzed and compared with the results of 20 laparoscopic right hepatectomies consecutively performed by the same young surgeon. <b><i>Results:</i></b> The overall mean operative time was less in robotic arm (425 ± 139 vs. 565.18 ± 183.73, <i>p</i> = 0.022) and the estimated blood loss was similar (335.15 ± 139.8 vs. 423.95 ± 205.15, <i>p</i> = 0.17); no blood transf…
