Prognostic factors associated with disability in a cohort of neuromyelitis optica spectrum disorder and MOG-associated disease from a nationwide Portuguese registry.

Introduction: Neuromyelitis optica spectrum disorders (NMOSD) and MOG-associated disease (MOGAD) are an increasingly recognized group of demyelinating disorders of the central nervous system. Previous studies suggest that prognosis is predicted by older age at onset, number of relapses, the severity of the first attack and autoantibody status.

Objective: To study prognostic factors associated with disability progression and additional relapses in the 3-year follow-up of a national NMOSD/MOGAD cohort.

Underwater Endoscopic Mucosal Resection Vs Conventional Endoscopic Mucosal Resection for Superficial Nonampullary Duodenal Epithelial Tumors in the Western Setting.

Background & Aims: Conventional endoscopic mucosal resection (C-EMR) is established as the primary treatment modality for superficial nonampullary duodenal epithelial tumors (SNADETs), but recently underwater endoscopic mucosal resection (U-EMR) has emerged as a potential alternative. The majority of previous studies focused on Asian populations and small lesions (≤20 mm). We aimed to compare the efficacy and outcomes of U-EMR vs C-EMR for SNADETs in a Western setting.

The use of two or more courses of low-dose systemic dexamethasone to extubate ventilator-dependent preterm neonates may be associated with a higher prevalence of cerebral palsy at two years of corrected age.

Background: Our objective was to determine whether the use of two or more courses of low-dose systemic dexamethasone for extubation of ventilator-dependent preterm infants after the first week of life, as proposed in the DART study, is associated with greater neurodevelopmental harm at two years of corrected age, compared to a single course.

Methods: Retrospective review at seven level III neonatal intensive care units. Preterm infants who underwent only one course of systemic dexamethasone for extubation were grouped into DART-1; those who underwent two or more courses were grouped into DART-2.

Endovascular therapy for posterior cerebral artery occlusion: systematic review with meta-analysis.

Endovascular therapy (EVT) is a highly effective stroke treatment, but trials validating this intervention did not include patients with posterior cerebral artery (PCA) occlusion. The aim of this systematic review with meta-analysis was to assess the efficacy and safety of EVT for acute PCA occlusion. PubMed, Scopus, ISI, and CENTRAL were searched for studies assessing EVT in adult patients with PCA occlusion.

Twelve-year trends in unprotected left main coronary artery occlusion: insights from a real-world multicentre study.

Aims: Acute myocardial infarction (AMI) resulting from unprotected left main coronary artery (LMCA) occlusion and subtotal occlusion is a life-threatening condition. Although AMI management has improved in the past two decades, there is limited information on recent trends in patient characteristics, management, and outcomes for acute unprotected LMCA-related AMI. This study aims to assess such trends over a 12 year period.

Management of infusion-related reactions in cancer therapy: strategies and challenges.

Several anticancer therapies have the potential to cause infusion-related reactions (IRRs) in the form of adverse events that typically occur within minutes to hours after drug infusion. IRRs can range in severity from mild to severe anaphylaxis-like reactions. Careful monitoring at infusion initiation, prompt recognition, and appropriate clinical assessment of the IRR and its severity, followed by immediate management, are required to ensure patient safety and optimal outcomes.

Treatment Of Post-Operative Chylothorax: The Role Of Intranodal Lymphangiography And Thoracic Duct Disruption.

Thoracic duct embolization has been increasingly adopted as a first-line therapy of chylothorax and this procedure includes lipiodol lymphangiography, thoracic duct access and embolization. Lymphangiography itself has a therapeutic role, with volume-dependent success rates of 37%-97% and even a reported 100% success rate in outputs of < 500 mL/day. We present a clinical case of a 48-years-old man diagnosed with esophageal squamous cell carcinoma, who underwent esophagectomy and presented with post-operative high-output (> 1L/day) chylothorax; thoracic duct embolization was proposed.

Treatment of Greater Trochanteric Pain Syndrome With Ultrasound-Guided Bipolar Pulsed Radiofrequency of the Trochanteric Branches of the Femoral Nerve: A Case Series of Nine Patients.

Background: Greater trochanteric pain syndrome (GTPS) is a prevalent cause of lateral hip pain that often leads to significant functional limitations. Conservative treatment options include physical therapy, pharmacological treatment, and more invasive techniques such as corticosteroid injections. However, despite the high success rates reported with corticosteroid injections, a significant number of patients have their symptoms persist or recur.

Case Description: A 69-year-old female with history of JAK2 positive essential thrombocythemia (ET) was referred to internal medicine consultation due to elevated liver enzymes.

Tibiotalocalcaneal and Tibiotalar Arthrodesis for Severe Cavovarus Deformity: Tips and Tricks.

Cavovarus foot is a complex 3-dimensional deformity. Clinical history, physical examination, and comorbidity assessment are essential for preoperative evaluation. In severe cases, ankle or tibiotalocalcaneal arthrodesis can provide symptomatic relief and result in a plantigrade foot.

Challenges in Perioperative Cerebral Oximetry Monitoring: A Case of Clofazimine-Induced Skin Pigmentation Interference.

Perioperative stroke is a potentially devastating complication in patients undergoing noncardiac surgery. The most consistent risk factor associated with the condition is a history of a prior stroke. Cerebral oximetry is a simple, non-invasive, and continuous monitoring device that uses near-infrared spectroscopy (NIRS) to monitor cerebral oxygenation.

Microwave ablation of solitary T1N0M0 papillary thyroid carcinoma: A case report.

Background: The gold standard treatment for papillary thyroid carcinoma is total thyroidectomy and indications for microwave thermal ablation for primary thyroid cancers have not yet been clearly established However, some patients refuse surgery and others have no indication for it, for example patients under palliative care as in this case, or cannot undergo surgery, based on their comorbidities. These indications are described in the most recent Korean, North American and European guidelines. Laser ablation, radiofrequency ablation, and microwave ablation are similarly safe and effective, so the choice should be based on the specific competences and resources of the pertaining centers.
