Background: Urinary incontinence after radical prostatectomy is one of the most feared problems. It can affect almost 40% of patients, with different degrees of severity according to each specific case. The aim of this work is to analyze our experience in ProACT (Adjustable Continence Therapy) implants, especially in case of failure of other techniques.
Methods: Between November 2007 and December 2010, 31 patients with post-radical prostatectomy incontinence underwent a ProACT implant. Eight patients had their device explanted (in local anesthesia): in two cases the device spontaneously broke, three of them migrated in the urethra (one patient received radiation therapy), another one was infected in the device site (one in BCG treatment for non-muscle invasive bladder cancer), two devices were wrongly placed. Seven of these patients had had their device replaced with success. Using pad score, incontinence was classified as mild, moderate and severe. Overall, the total amount of procedures, most of them fluoroscopic-guided in spinal anesthesia, were 38; the average duration of the surgery was 37.6 minutes. In one patient with impaired balloon volume due to monolateral device malfunction, we noticed good results in controlling incontinence; therefore, we successfully applied the same technique in other four cases with previous partial results.
Results: With a total amount of 28 implants, we had 17 (60.7%) complete responses, 6 (25%) partial and 4 (14.3%) failures. We had 4 post-radiotherapy implants: one was completely dry, two were in balloon adjustment, and one of them had a replacement due to urethral erosion of the first implant.
All patients with impaired balloon inflation were satisfied: one was completely dry and three had sensible improvement.
Conclusions: The ProACT is a minimally invasive surgical therapy for post-radical prostatectomy urinary incontinence. Early failure is frequent and is mainly due to rupture and migration of the device. In these cases the solution can be the replacement, even with impaired balloon inflation.

Background: ST-elevation myocardial infarction (STEMI) demands near-time reperfusion to reduce the risk of long-term heart failure. This study evaluates the proportion of impaired left ventricular ejection fraction (LVEF) following STEMI in the context of current healthcare settings at a tertiary care center equipped with the most advanced and up-to-date standards of care.
Methods: Patients experiencing STEMI as their first manifestation of coronary artery disease were analyzed, as these individuals had no prior experience with heart-related chest pain.

An adherent placenta is a life-threatening condition that impairs the mother's life owing to hemorrhagic shock and disseminated intravascular coagulation. Profound hemorrhage resulting from placental abruption is often managed using hysterectomy to preserve the mother's life, although the consequent loss of fertility can be devastating, particularly in younger women. Thus, strategies that facilitate fertility preservation while effectively controlling hemorrhage should be considered viable alternatives.

Superior vena cava (SVC) syndrome is a result of impaired blood flow from the SVC to the right atrium, leading to venous congestion in the head and neck. It can be caused by clotting disorders or compressive tumors of the head and neck but has become more prevalent in the setting of implantable devices such as pacemakers. As such, managing these patients can present challenges for physicians who have to account for SVC syndrome as well as their underlying condition requiring an implantable cardiac device.

Foley balloons have been used to secure emergency hemostasis for cardiac or vascular injuries since the 1960s. However, using a single large balloon may have drawbacks, such as insufficient hemostasis and blood flow impairment. We have encountered 3 major intraoperative laceration cases since 2011.

Robust preclinical models of asymmetric ventricular loading in late gestation reflecting conditions such as hypoplastic left heart syndrome are lacking. We characterized the morphometry and microvascular function of the hypoplastic left ventricle (LV) and remaining right ventricle (RV) in a sham-controlled late gestation fetal lamb model of impaired left ventricular inflow (ILVI). Singleton fetuses were instrumented at ∼120 days gestational age (dGA; term is ∼147 days) with vascular catheters, an aortic flow probe and a deflated left atrial balloon.
