Bilateral external iliac artery pseudoaneurysms causing urinary obstruction and acute renal failure.

Background: We report an exceedingly rare case of bilateral external iliac artery pseudoaneurysms causing urinary obstruction and acute renal failure.

Case Presentation: A young man presented with acute severe bilateral testicular pain radiating to the back. Clinical and radiological workup showed bilateral external iliac artery pseudoaneurysms, which caused bilateral ureterohydronephrosis due to urinary obstruction with subsequent renal failure.

Initial experience with Duplex scan combined with contrast-enhanced ultrasound for follow-up of endovascular abdominal aortic aneurysm repair.

Background: Microbubble contrast enhanced ultrasound (CEUS) is an accurate diagnostic method for follow-up after endovascular abdominal aortic aneurysm repair (EVAR) that has been well-established in international studies. However, there are no Brazilian studies that focus on this follow-up method.

Objectives: The objective of this study was to report initial experience with CEUS at a tertiary hospital, comparing the findings of CEUS with those of conventional Doppler ultrasound (DUS), with the aim of determining whether addition of contrast to the standard ultrasonographic control protocol resulted in different findings.

Pseudoaneurysm and arteriovenous fistula of the deep femoral artery after complete rupture of the vastus medialis muscle: endovascular treatment.

Due to its anatomical characteristics, the deep femoral artery is protected from most vascular injuries. We report a case of a soccer player with pseudoaneurysm of a perforating branch of the deep femoral artery, associated with an arteriovenous fistula and secondary to complete rupture of the vastus medialis muscle. Magnetic resonance imaging showed muscle damage associated with a pseudoaneurysm and angiotomography confirmed the presence of a pseudoaneurysm associated with a deep arteriovenous fistula of a branch of the deep femoral artery.

Cohort study on 20 years' experience of bilateral video-assisted thoracic sympathectomy (VATS) for treatment of hyperhidrosis in 2431 patients.

Background: Primary hyperhidrosis is a condition characterized by excessive sweating, inconsistent with the needs for thermoregulation.

Objective: To assess the effectiveness and the change in the quality of life of patients undergoing bilateral VATS (video-assisted thoracoscopic sympathectomy) for treatment of hyperhidrosis, in a large case series.

Design And Setting: Cohort study conducted in a tertiary hospital specializing in hyperhidrosis located in São Paulo, Brazil.

Use of carbon dioxide for therapeutic decision-making in endoleaks: a case report.

Endovascular aneurysm repair is currently the most frequently treatment modality for infrarenal aortic aneurysms. Endoleaks are the most common cause of reintervention after endovascular aneurysm repair. It is often unclear which type of endoleak is the correct diagnose, making the treatment decision difficult.

Current treatment options for craniofacial hyperhidrosis.

Hyperhidrosis (HH) is characterized by sweating exceeding the amount necessary to meet the thermal regulation and physiological needs of the body. Approximately 9.41% of individuals with HH have craniofacial hyperhidrosis (FH).

Endovascular Therapy Provides Similar Results of Bypass Graft Surgery in the Treatment of Infrainguinal Multilevel Arterial Disease in Patients with Chronic Limb-Threatening Ischemia in All GLASS Stages.

Background: Extensive infrainguinal arterial disease still pose a challenge for technical and clinical success of percutaneous angioplasty. The purpose of this study was to compare the results of concomitant femoropopliteal and infrapopliteal percutaneous angioplasty/stenting (PTA/S) with distal bypass graft surgery (BGS) in patients with chronic limb-threatening ischemia (CLTI).

Method: In a single-center retrospective investigation between 2011 and 2017, 668 revascularization procedures for CLTI were reviewed.

Long-term results of the treatment of primary hyperhidrosis with oxybutynin: follow-up of 1,658 cases.

Background: Hyperhidrosis (HH) is characterized by exaggerated sweating in a specific region due to hyperfunction of the sweat glands. In the late 2000s, we started treating patients with an anticholinergic, oxybutynin, that was not being used until then.

Objectives: To present, after 12 years of utilizing this medication in our service, the substantial experience obtained with the use of oxybutynin as an initial treatment of HH in a large series of 1,658 patients.

Comparative analysis of the results of videothoracoscopic sympathectomy in the treatment of hyperhidrosis in adolescent patients.

Objective: Several factors that could influence the efficacy and satisfaction of patients after bilateral thoracic sympathectomy (VATS) in the treatment of hyperhidrosis (HH) have been studied, but no studies in the literature have specifically analyzed the effectiveness of treatment and variations in the quality of life of adolescents patients compared to those of adult patients (18-40 years).

Methods: We retrospectively analyzed 2431 hyperhidrosis patients who underwent bilateral VATS and divided the patients into the following groups: adolescents (472 patients) and adult group (1760 patients). Variables included quality of life prior to surgery, improvement in quality of life after surgery, clinical improvement in sweating, presence of severe compensatory hyperhidrosis and general satisfaction at one month after surgery.

Analysis of the Results of Videotoracoscopic Sympathectomy in the Treatment of Hyperhidrosis in Patients 40 Years or Older.

Background: Several factors that could influence the efficacy and satisfaction of patients after bilateral thoracic sympathectomy (video-assisted thoracoscopic sympathectomy [VATS]) in the treatment of hyperhidrosis (HH) have been studied, but no studies in the literature have specifically analyzed the effectiveness of treatment and variations in the quality of life of patients aged 40 years or older compared with those of young adult patients (19-40 years).

Methods: We retrospectively analyzed 2,431 HH patients who underwent bilateral VATS and divided the patients into the following groups: a group younger than 40 years old (1,760 patients) and a group 40 years and older (142 patients). Variables included quality of life before surgery, improvement in quality of life after surgery, clinical improvement in sweating, the presence of severe compensatory hyperhidrosis (CH), and general satisfaction at 1 month after surgery.

Intranasal Administration of Type V Collagen Reduces Lung Carcinogenesis through Increasing Endothelial and Epithelial Apoptosis in a Urethane-Induced Lung Tumor Model.

Type V collagen (Col V) is a "minor" component of normal lung extracellular matrix, which is subjected to decreased and abnormal synthesis in human lung infiltrating adenocarcinoma. We previously reported that a direct link between low amounts of Col V and decreased cell apoptosis may favor cancer cell growth in the mouse lung after chemical carcinogenesis. Moreover, this collagen species was able to trigger DNA fragmentation and impair survival of neoplastic cells.
