Revolutionizing palliative care: Electrocautery-enhanced lumen-apposing metal stents in endoscopic-ultrasound-guided biliary drainage for malignant obstructions.

Patients with malignant biliary obstruction, following endoscopic retrograde cholangiopancreatography (ERCP) failure could be referred for endoscopic-ultrasound-guided biliary drainage through electrocautery-enhanced (ECE) lumen-apposing metal stent (LAMS) placement. However, the efficacy and safety of ECE-LAMS in this scenario have remained debatable due to minimal scientific evidence. The current confirmed 91.0% clinical success, 96.7% technical success, 7.3% reintervention rate, and 17.5% adverse events, following the treatment of malignant biliary obstruction with ECE-LAMS delivery. Finally, ECE-LAMS proved to be a generalizable strategy for managing biliary obstruction for patients who were excluded from ERCP.

Spontaneous Subdiaphragmatic Hemorrhage From an Aneurysm of Inferior Phrenic Artery.

Inferior phrenic artery (IPA) aneurysms are the rarest type of visceral aneurysms. It usually occurs secondary to trauma, surgery, or as a complication of pancreatitis. In addition, it can be a manifestation of underlying systemic pathology such as vasculitis, collagen vascular disorders, sepsis, or segmental arterial mediolysis. It can be associated with hypertension in 43% of cases. The presentation of IPA aneurysm is nonspecific with abdominal pain, melena, hematochezia, and anemia. The ruptured and actively bleeding aneurysm can lead to hemorrhagic shock, and immediate management is required with angiography and endovascular embolization with coil or gel foam or stent etc. Inaccessible locations are reached with surgical intervention, but it is associated with high morbidity and mortality. We here report a rare case of spontaneously ruptured IPA pseudoaneurysm extending from the posterior mediastinum to the subdiaphragmatic area and managed with coil and gel foam embolization.

Bevacizumab-Induced Nephropathy Presenting as Crescentic Glomerulopathy.

Bevacizumab-induced nephropathy is a common adverse event observed in patients who receive chemotherapy. These patients usually present with hypertension and nephrotic range proteinuria. Thrombotic microangiopathy is the characteristic histologic pattern of bevacizumab-induced nephropathy. However, a few cases reported IgA vasculitis with nephritis as an unusual pattern. In this case report, we describe a patient diagnosed with bevacizumab-induced nephropathy with a distinctive histologic pattern demonstrating focal proliferative crescentic glomerulonephritis with polyclonal immune complex deposition.

Multicentric Reticulohistiocytosis Presenting As Acute Pericarditis With Moderate-Sized Pericardial Effusion: A Case Report and Review of Multicentric Reticulohistiocytosis Treatment.

Multicentric reticulohistiocytosis (MRH) is a rare, class IIb non-Langerhans cell histiocytosis associated with skin and joint involvement. It is more prevalent (80%) in Caucasian females in their fifth to sixth decade of life. Patients usually demonstrate symptoms and signs of symmetric polyarthritis and papulonodular cutaneous lesions. In addition to skin and joints, multiple organs can be involved, such as the lung (pleural effusion, interstitial fibrosis, hilar lymphadenopathy), heart (pericardial effusion, myocarditis), gastrointestinal system, and urogenital system (genital tract and kidney). Pericardial involvement is a rare manifestation, and around three cases have been reported in the literature so far. Our case report is a valuable contribution to the literature, which aids clinicians in contemplating MRH as one of the differentials among patients presenting with pericardial effusion. We described the characteristics of MRH along with its differentiating features from other autoimmune conditions and management.
