Combined Treatment of Uterine Arteriovenous Malformation Using a 16 Fr Miniresectoscope in an Office Setting Without Anesthesia: A Case Report.

Arteriovenous malformations (AVMs) are abnormal connections between arteries and veins that bypass the capillary system. Among AVMs, uterine ones are very rare, and it is not possible to have clear data on their incidence, as a good part of the patients remain clinically asymptomatic. Uterine AVMs consist of abnormal communications between branches of the uterine artery and the myometrial venous plexus.

Candidiasis in Pregnancy: Relevant Aspects of the Pathology for the Mother and the Fetus and Therapeutic Strategies.

Vulvovaginal candidiasis (VVC) is a common condition that can lead to significant discomfort, affecting approximately 70-75% of women at least once in their lives. During pregnancy, the prevalence of VVC is estimated to be around 20%, peaking at about 30% in the third trimester, with a number of specific risk factors predisposing to yeast infection being identified and needing elucidation. This review aims to provide updated knowledge on candidiasis during pregnancy, addressing risk factors and maternal and neonatal outcomes, as well as discussing optimal therapeutic strategies to safeguard mothers and newborns.

Clinical efficacy of the first two doses of anti-SARS-CoV-2 mRNA vaccines in solid cancer patients.

Introduction: Cancer patients are frail individuals, thus the prevention of SARS-CoV-2 infection is essential. To date, vaccination is the most effective tool to prevent COVID-19. In a previous study, we evaluated the immunogenicity of two doses of mRNA-based vaccines (BNT162b2 or mRNA-1273) in solid cancer patients.

Immunogenicity of two doses of BNT162b2 and mRNA-1273 vaccines for solid cancer patients on treatment with or without a previous SARS-CoV-2 infection.

Previous studies on the immunogenicity of SARS-CoV-2 mRNA vaccines showed a reduced seroconversion in cancer patients. The aim of our study is to evaluate the immunogenicity of two doses of mRNA vaccines in solid cancer patients with or without a previous exposure to the virus. This is a single-institution, prospective, nonrandomized study.

Screening for hemodialysis graft stenosis and short-term thrombosis risk: A comparison of the available tools.

Introduction: Guidelines recommend hemodialysis graft screening to identify and repair significant (>50%) stenosis at high risk of thrombosis, but there is insufficient evidence to prefer one or other screening tool due to the lack of studies comparing all available options.

Methods: Seeking an optimal screening approach, we compared the performance of all currently used tools (duplex ultrasound to detect significant stenosis (StD) and measure access blood flow (QaD), ultrasound dilution access blood flow (QaU), static venous intra-access pressure ratio (VAPR), dynamic arterial and venous pressures measurement, and monitoring) for diagnosing significant angiography-proven stenosis (StA) and predicting incipient thrombosis (occurring within 4 months) in 62 grafts. All thrombotic and symptomatic acute hypotension episodes were recorded during follow-up.

Pancreatectomy with venous resection for pT3 head adenocarcinoma: Perioperative outcomes, recurrence pattern and prognostic implications of histologically confirmed vascular infiltration.

Background: The outcomes of pancreatectomy with superior mesenteric vein (SMV) or portal vein (PV) resection have been mixed. This study investigated the morbidity and mortality profile after SMV-PV resection in comparison with standard pancreatectomy. Furthermore, we assessed whether tumors with histologically proven SMV-PV infiltration differ from other pT3 neoplasms in terms of recurrence pattern and survival.

Are strong opioids equally effective and safe in the treatment of chronic cancer pain? A multicenter randomized phase IV 'real life' trial on the variability of response to opioids.

Background: Guidelines tend to consider morphine and morphine-like opioids comparable and interchangeable in the treatment of chronic cancer pain, but individual responses can vary. This study compared the analgesic efficacy, changes of therapy and safety profile over time of four strong opioids given for cancer pain.

Patient And Methods: In this four-arm multicenter, randomized, comparative, of superiority, phase IV trial, oncological patients with moderate to severe pain requiring WHO step III opioids were randomly assigned to receive oral morphine or oxycodone or transdermal fentanyl or buprenorphine for 28 days.

Sustainable Sourcing of Global Agricultural Raw Materials: Assessing Gaps in Key Impact and Vulnerability Issues and Indicators.

Understanding how to source agricultural raw materials sustainably is challenging in today's globalized food system given the variety of issues to be considered and the multitude of suggested indicators for representing these issues. Furthermore, stakeholders in the global food system both impact these issues and are themselves vulnerable to these issues, an important duality that is often implied but not explicitly described. The attention given to these issues and conceptual frameworks varies greatly--depending largely on the stakeholder perspective--as does the set of indicators developed to measure them.

Treatment of an aneurysm of the celiac artery arising from a celiomesenteric trunk. Report of a case.

Introduction: Visceral artery aneurysms (VAA) are rare, frequently present as a life-threatening emergency and are often fatal. The celiacomesenteric trunk (CMT), a common origin of the celiac trunk (CT) and the superior mesenteric artery (SMA) from abdominal aorta, is quite rare. Aneurysms that involve this celiomesenteric anomaly are even rarer and in the last 32 years have been reported in only 20 cases in the literature.

Do oxidized polyunsaturated Fatty acids affect endoplasmic reticulum stress-induced apoptosis in human carotid plaques?

Macrophage apoptosis is involved in atherosclerotic plaque development. The aim of this study was to evaluate the interrelationship between macrophage apoptosis and the endoplasmic reticulum (ER) stress in the tissue around the necrotic core (TANC) and in the periphery (P) of the same carotid plaques derived from patients undergoing carotid endarterectomy. Apoptosis was significantly higher in TANC than in P (p<0.

Should current criteria for detecting and repairing arteriovenous fistula stenosis be reconsidered? Interim analysis of a randomized controlled trial.

Background: The vascular access guidelines recommend that arteriovenous fistulas (AVFs) with access dysfunction and an access blood flow (Qa) <300-500 mL/min be referred for stenosis imaging and treatment. Significant (>50%) stenosis, however, may be detected in a well-functioning AVF with a Qa > 500 mL/min, too, but whether it is worth correcting or not remains to be seen.

Methods: In October 2006, we began an open randomized controlled trial enrolling patients with an AVF with subclinical stenosis and Qa > 500 mL/min, to see how elective stenosis repair [treatment group (TX)] influenced access failure (thrombosis or impending thrombosis requiring access revision), or loss and the related cost compared with stenosis correction according to the guidelines, i.

Expansion of necrotic core and shedding of Mertk receptor in human carotid plaques: a role for oxidized polyunsaturated fatty acids?

Aims: Expansion of necrotic core (NC), a major feature responsible for plaque disruption, is likely the consequence of accelerated macrophage apoptosis coupled with defective phagocytic clearance (efferocytosis). The cleavage of the extracellular domain of Mer tyrosine kinase (Mertk) by metallopeptidase domain17 (Adam17) has been shown to produce a soluble Mertk protein (sMer), which can inhibit efferocytosis. Herein, we analysed the expression and localization of Mertk and Adam17 in the tissue around the necrotic core (TANC) and in the periphery (P) of human carotid plaques.

In search of an optimal bedside screening program for arteriovenous fistula stenosis.

Background And Objectives: Guidelines recommend systematically screening for stenosis using various methods, but no studies so far have compared all of the options. A prospective blinded study was performed to compare the performance of several bedside tests performed during dialysis in diagnosing angiographically proven >50% fistula stenosis.

Design, Setting, Participants, & Measurements: In an unselected population of 119 hemodialysis patients with mature fistulas, physical examination (PE) was conducted; dynamic and derived static venous pressure (VAPR), blood pump flow/arterial pressure (Qb/AP) ratio, recirculation (R), and access blood flow (Qa) were measured; and angiography was performed.

Bedside screening for fistula stenosis should be tailored to the site of the arteriovenous anastomosis.

Background And Objectives: Given different sites of stenosis and access blood flow rates (Qa), the criteria for diagnosing fistula stenosis might vary according to anastomotic site. To test this, we analyzed the database of a prospective blinded study seeking an optimal bedside screening program for fistula stenosis.

Design, Setting, Participants, & Measurements: Several methods used during dialysis (physical examination [PE], dynamic and derived static venous pressure [VAPR], dialysis blood pump flow/arterial pressure ratio, and Qa measurement) to diagnose angiographically-proven >50% stenosis were assessed in an unselected population of hemodialysis patients with mature fistulae (43 at the wrist [distal fistulae], 76 at mid-forearm or the elbow [proximal fistulae]).

The role of splenectomy in myelofibrosis with myeloid metaplasia.

Aim: In this paper we retrospectively analyzed prospectively-collected data on our myelofibrosis with myeloid metaplasia (MMM) patients who underwent splenectomy. The aim was to ascertain the hematological response and any resolution of symptoms existing prior to splenectomy; redefining timing and role of splenectomy in the treatment of MMM.

Methods: This prospective study considered 31 patients with MMM who underwent splenectomy for transfusion-dependent anemia, thrombocytopenia, abdominal swelling and pain.

Adding access blood flow surveillance to clinical monitoring reduces thrombosis rates and costs, and improves fistula patency in the short term: a controlled cohort study.

Background: Access blood flow (Qa) measurement is the recommended method for fistula (AVF) surveillance for stenosis, but whether it may be beneficial and cost-effective is controversial.

Methods: We conducted a 5-year controlled cohort study to evaluate whether adding Qa surveillance to unsystematic clinical monitoring (combined with elective stenosis repair) reduces thrombosis and access loss rates, and costs in mature AVFs. We prospectively collected data in 159 haemodialysis patients with mature AVFs, 97 followed by unsystematic clinical monitoring (Control) and 62 by adding Qa surveillance to monitoring (Flow).

Endovascular versus surgical preemptive repair of forearm arteriovenous fistula juxta-anastomotic stenosis: analysis of data collected prospectively from 1999 to 2004.

Surgery is the traditional treatment for juxta-anastomotic stenoses in forearm arteriovenous fistulas (AVF), but percutaneous transluminal angioplasty (PTA) is a suitable alternative. No prospective comparative trials between the two have been reported to date, however. A retrospective analysis of prospectively, concurrently collected data was performed to compare the outcome and cost of surgery and PTA in the preemptive repair of juxta-anastomotic stenosis in lower forearm AVF.

Outcomes of surgical revision of stenosed and thrombosed forearm arteriovenous fistulae for haemodialysis.

Background: Surgery is an established treatment for stenosed and thrombosed forearm arteriovenous fistulae (AVFs), but the literature on its outcome is limited. We report our experience of the surgical repair of stenosis in patent and thrombosed forearm AVFs and evaluate the outcome of two procedures, proximal neo-anastomosis (NEO) vs replacement of the stenosed segment with a polytetrafluoroethylene graft interposition (GI).

Methods: Sixty-four stenosed forearm AVFs underwent surgery, 32 pre-emptively and 32 post-thrombosis.

[Internal carotid artery aneurisms: two cases].

Introduction: Aneurysms of the extracranial portion of the internal carotid artery (ICA) are rare (accounting for only 0.1-2% of all surgical procedures affecting the ICA, 0.4-1% of all arterial aneurysms, and 4% of all aneurysms involving peripheral arteries), but they are nonetheless clinically significant because of the high related risk of cerebral thromboembolism.

[Laparoscopic treatment of liver hydatid cyst: personal technique].

Treatment of liver hydatid cyst is still controversial. Besides medical treatment, interventional radiologic techniques and traditional surgery, recently the laparoscopic approach has been proposed. Laparoscopic treatment of liver hydatid cyst, however, has not been well defined so far and seems to be associated with a recurrence rate from 0 to 9%, in a 3-49 months follow-up.

[Treatment of celiac trunk aneurysms: personal experience and review of the literature].

Introduction: Celiac trunk aneurysms represent 4% of all splanchnic artery aneurysms. These lesions are thus extremely rare but yet have a significant clinical importance. Mortality, mainly related to site characteristics, is a significant risk (14%) in the event of rupture.

Laparoscopic splenectomy reduces the need for platelet transfusion in patients with idiopathic thrombocytopenic purpura.

Objectives: Laparoscopic splenectomy has been increasingly used in patients with idiopathic thrombocytopenic purpura. Because it is associated with minimal abdominal trauma, platelet consumption could be reduced with the laparoscopic approach. The aim of this study was to analyze intraoperative bleeding and the need for apheresis platelets, comparing laparoscopic with open splenectomy.

Diagnosis of pelvic endometriosis with use of macroscopic versus histologic findings.

Objective: To obtain histologic confirmation of lesions suspected of endometriosis at laparoscopy.

Design: Prospective clinical study.

Setting: Patients in an academic hospital.

Managing anomalous splenic artery aneurysm: a review of the literature and report of two cases.

The splenic artery originates from the superior mesenteric artery in approximately 1% of cases, which may explain the extreme rarity of aneurysms involving this anomalous branch, with only five cases reported in the international literature to date. We report our experience of managing two patients with aneurysms involving splenic arteries arising from the superior mesenteric artery, one treated surgically and the other percutaneously. From a diagnostic point of view, the first approach is ultrasound, while computed tomographic (CT) scan and angiography enable a better definition of the lesion and of the anatomical anomaly; CT angiography is currently the method of choice for the preoperative workup.

Can blood flow surveillance and pre-emptive repair of subclinical stenosis prolong the useful life of arteriovenous fistulae? A randomized controlled study.

Background: Stenosis is the main cause of arteriovenous fistula (AVF) failure. It is unclear, however, if surveillance for stenosis enhances AVF function and longevity and if there is an ideal time for intervention.

Methods: In a 5-year randomized, controlled, open trial we compared blood flow surveillance and pre-emptive repair of subclinical stenoses (one or both of angioplasty and open surgery) with standard monitoring and intervention based upon clinical criteria alone to determine if the former prolonged the longevity of mature forearm AVFs.
