Dilation of the ductus venosus by stent implantation increases placental blood perfusion in fetal sheep.
2006
The reduction of resistance to flow in the ductus venous (DV) and a decrease of blood supply to the liver serve for the survival of the fetus during hypoxia. The present study investigated the influence of the increased diameter of the DV on placental blood perfusion.In 15 ewes with twin pregnancies at gestational ages of 117 +/- 4 days, a stent (4 or 5 mm) was placed into the DV of 1 twin (DV(stent) group) under ultrasound guidance. Blood flow rates in the umbilical vein (UV) and DV of both fetuses were measured using Doppler ultrasound. Eight pairs of twin fetuses were included for the final analysis.The dilatation of the DV increased the blood flow volume rate passed through the DV from …
Anatomical basis for the interposition of a gastric pouch between the ileum and the anus after total proctocolectomy.
2003
After a total proctocolectomy, ileoanal continuity is achieved by an ileal pouch–anal anastomosis. This anastomosis is not possible when the ileum cannot reach the anus. To avoid definitive ileostomy in this circumstance, we devised a gastric pouch, taken from the left half of the vertical portion of the stomach, vascularized by the right gastroepiploic pedicle, then interposed it between the ileum and the anus. The aim of this anatomical study on seven cadavers was to estimate the capacity of this gastric pouch to reach the anus. The distance between the caudal edge of the pubic symphysis and the apex of the pouch was measured. It is accepted that an ileal pouch always reaches the anus wit…
Is a Vaginectomy Enough or is a Pelvic Exenteration Always Required for Surgical Treatment of Recurrent Cervical Cancer? A Propensity-Matched Study.
2021
Purpose: Reporting the perioperative and survival outcomes of vaginectomy with respect to a matched series of pelvic exenteration (PE) in women with isolated recurrent cervical cancer. Methods: The records of vaginal recurrent cervical cancer patients admitted at Fondazione Policlinico “Agostino Gemelli” IRCCS in Rome from January 2010 to June 2019 were retrospectively analyzed. A propensity-matched score analysis was performed by age, clinical stage, disease-free interval, and R0 resection. Postsurgical complications and survival rates were evaluated. Results: Fifteen women underwent vaginectomy, and 30 patients were submitted to PE. No statistical differences were observed between the two…
Correlation of preoperative imaging characteristics with donor outcomes and operative difficulty in laparoscopic donor nephrectomy
2019
This study aimed to understand the relationship of preoperative measurements and risk factors on operative time and outcomes of laparoscopic donor nephrectomy. Two hundred forty-two kidney donors between 2010 and 2017 were identified. Patients' demographic, anthropomorphic, and operative characteristics were abstracted from the electronic medical record. Glomerular filtration rates (GFR) were documented before surgery, within 24 hours, 6, 12, and 24 months after surgery. Standard radiological measures and kidney volumes, and subcutaneous and perinephric fat thicknesses were assessed by three radiologists. Data were analyzed using standard statistical measures. There was significant correlat…
Official Statement of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) on Electronic Cigarettes and IQOS®.
2019
The use of novel tobacco products, particularly the electronic cigarette (EC) and partial tobacco combustion devices (HnB systems: Heat not Burn), has increased exponentially, particularly among adolescents and young people. The health authorities and scientific societies have shown concern about issues surrounding safety and effectiveness (as a method of smoking cessation). A study of the available scientific evidence has concluded that the safety of the vapor or fumes inhaled by the users of these devices cannot be guaranteed. Contradictory results from various clinical trials and meta-analyses also mean that these devices cannot be recommended for their effectiveness in cessation, especi…
Multilevel diabetic foot revascularization in COVID 19 patient: Case report
2021
Abstract Introduction Coronavirus 2019 (COVID-19) has been associated with endothelial dysfunction. This hypercoagulable state coming from the endothelial injury pones COVID-19 patients to a higher risk for thrombosis. COVID 19 diabetic patients are more exposed to peripheral vascular disease progression. Multilevel peripheral arterial disease is the main cause of critical limb ischemia. Vascular interventions are required to increase distal blood flow and reduce the risk of amputation. Presentation of case We report a case of complex revascularization in a diabetic patient with aggressive right foot lesions evolution after COVID-19 infection. The patient presenting a Peripheral arterial is…
Endoscopic management of gastric outlet obstruction disease
2019
Gastric outlet obstruction (GOO) is a clinical syndrome characterized by a variety of symptoms. It may be caused by motor disorders and by benign or malignant mechanical disease. Endoscopic management of benign disease is mainly based on balloon dilation, augmented by the use of covered self-expanding metal stents (SEMS) in refractory disease. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is increasingly used as an alternative method, although more studies with longer follow up are needed before it can be considered as a recommended therapy. Surgery remains the last resort. Endoscopic management of malignant GOO is based on SEMS placement as an alternative to palliative surgery, b…
Assessment of clinical outcomes and histomorphometric findings in alveolar ridge augmentation procedures with allogeneic bone block grafts: A systema…
2020
Background This systematic literature review aimed to evaluate the efficacy of allogeneic bone blocks for ridge augmentation by assessing block survival rates and subsequent implant survival, including post-surgical complications and histomorphometric analysis. Material and Methods An electronic and manual search among references, was conducted up to April 2019 by two independent authors. Inclusion criteria were: human clinical trials in which the outcomes of allogeneic bone block grafts were evaluated by means of their survival rates and subsequent implant success rates. Results Seven articles fulfilled the inclusion criteria and were analyzed. A total of 323 allogeneic block grafts were m…
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…
Review of ultrasonic irrigation in endodontics: increasing action of irrigating solutions
2011
Introduction: Effective irrigant delivery and agitation are prerequisites for successful endodontic treatment. Ultrasonic irrigation can be performed with or without simultaneous ultrasonic instrumentation. Existing literature reveals that ultrasonic irrigation may have a very positive effect on chemical, biological and physical debridement of the root canal system as investigated in many in vitro studies. Objective: The purpose of this review article was to summarize and discuss the available information concerning ultrasonic irrigation in endodontics. Methods: This article presents an overview of ultrasonic irrigation methods and their debridement efficacy. In this paper the relevant lite…
