El Síndrome de Takotsubo es una disfunción ventricular aguda reversible en ausencia de obstrucción coronaria. Una mujer de 85 años de edad con antecedentes de reemplazo valvular aórtico transcatéter, ingresó por dos semanas de dolor severo por una cadera desplazada por osteosíntesis fallida. Mientras se programaba para cirugía, se documentó hiponatremia severa secundaria a secreción inapropiada de hormona antidiurética. Súbitamente desarrolló edema agudo pulmonar. El ecocardiograma confirmó una válvula protésica funcional y aquinesia medial y apical de las paredes del ventrículo izquierdo. Recibió tratamiento con ventilación mecánica no invasiva, restricción de líquidos y diuréticos. La hiponatremia y la cardiomiopatía resolvieron. Takotsubo syndrome is a form of acute reversible left ventricular dysfunction in the absence of coronary obstruction. An 85-year-old lady with a medical history of transcatheter aortic valve replacement was readmitted complaining of 2 weeks of severe pain by a displaced hip and failed osteosynthesis. While she was scheduled for hip surgery, severe hyponatremia secondary to inappropriate antidiuretic hormone secretion was documented, and sudden-onset pulmonary edema ensued. Echocardiography confirmed normally functioning aortic prosthetic valve and classical features of Takotsubo. She was treated with non-invasive mechanical ventilation, water restriction, and diuretics. Hyponatremia and the cardiomyopathy resolved and the patient recovered completely.

Introduction: Endocrine paraneoplastic syndromes (ePNS) are caused by malignant cells that induce hormonal alterations unrelated to the tissue of origin of the neoplasm. The aim of this manuscript is to review the pathophysiology, diagnosis, and treatment of endocrine paraneoplastic syndromes (ePNS).
Areas Covered: We searched the PubMed/Medline, Embase, and Scielo databases, including 96 articles.

Background: NK-1 receptor antagonists (NK-1RAs) are proven to be successful in preventing chemotherapy-induced nausea and vomiting (CINV). The safety profile of NK-1RAs has not been systematically analyzed in the real world. This pharmacovigilance study investigated the differences in adverse events (AEs) between NK-1RAs.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a frequent cause of hyponatremia that presents substantial management challenges in clinical settings. Despite a range of treatment options, including fluid restriction, demeclocycline, and vasopressin antagonists, urea remains underutilized, particularly in North America, despite its well-documented efficacy, safety, and cost-effectiveness. Urea corrects hyponatremia by promoting osmotic diuresis without causing significant fluid shifts, making it an ideal treatment for both acute and chronic SIADH.

We reported the diagnostic and therapeutic process of a young male patient with systemic lupus erythematosus (SLE) who presented with severe hyponatremia as the main manifestation upon admission, and analyzed and discussed the case. The patient was a 19-year-old young male with a subacute course of disease, fever ≥38.3 ℃ that could not be explained by other causes, acute and subacute cutaneous lupus erythematosus, oral ulcers, arthritis, leukopenia (< 4×10/L), low C3+low C4, and positive anti-double-stranded DNA (anti-dsDNA).

Introduction: Olfactory neuroblastoma (ONB) is a rare malignant tumor originating from the olfactory neuroepithelium, typically within the sinonasal cavity. Cases of ONB originating outside of the olfactory cleft area are extremely rare and are referred to as "ectopic" (eONB), in contrast to "orthotopic" tumors (oONB). ONB has been associated with paraneoplastic syndromes (PNSs), including the syndrome of inappropriate antidiuretic hormone secretion (SIADH).
