RESUMEN

OBJECTIVE: Nelson syndrome (NS) is a rare clinical disorder that can occur after total bilateral adrenalectomy (TBA), performed as a treatment for Cushing disease. NS is defined as the accelerated growth of an adrenocorticotropic hormone-producing pituitary adenoma. Our objective is to describe a case of NS and discuss it based on existing knowledge of this syndrome. METHODS: We describe the case of a woman diagnosed with NS at our facility in the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran and review published cases of NS. RESULTS: The patient, a 35-year-old woman with Cushing disease, had been diagnosed in 2006 at the endocrinology department in the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran. In 2007, a laparoscopic TBA was performed, and 2 years later, she presented with hyperpigmentation and adrenocorticotropic hormone levels of up to 11 846 pg/mL. NS was suspected, and as magnetic resonance imaging showed macroadenoma, transsphenoidal surgery was performed. The patient remained asymptomatic until 2012, when she presented with a right hemicranial headache, photophobia, and phonophobia. A fresh magnetic resonance imaging was performed, which documented tumor growth. She was referred to the Instituto Nacional de Neurologia y Neurocirugia, where she underwent surgery. CONCLUSION: NS develops as a complication of TBA, which is used as a treatment of Cushing disease. The main treatment is surgery and radiotherapy.

RESUMEN

Abstract Objective: The objective of this study was to describe the case of a 19-year-old male presenting with bradycardia and hypotension after a honeybee sting making a review of the literature and pathophysiology of the cardiovascular and electrocardiogram (EKG) changes after a bee sting. Methods: The patient's airway was inspected and secured. Electrocardiogram with an idioventricular rhythm at 41' bpm. Oxygen was administered, an intravenous access was established, and the transcutaneous pacemaker leads were placed on the chest of the patient, then published guidelines management was induced. Results: The EKG showed idioventricular rhythm at a rate of 41 beats/min that resolved to a normal sinus rhythm after treatment. Conclusions: A full and prompt cardiovascular evaluation should be performed in all patients presenting to the emergency department after a bee sting, and published guidelines regarding the management of bradycardia and anaphylaxis should be followed to achieve successful outcomes.

Resumen Objetivo: Describir el caso de un paciente masculino de 19 años que presenta bradicardia e hipotensión después de una picadura de abeja haciendo una revisión de la literatura y fisiopatología de los cambios cardiovasculares y electrocardiográficos después de una picadura de abeja. Métodos: Se inspeccionó y aseguró la vía aérea del paciente. Un rastreo de ECG realizado al ingreso reveló ritmo idioventricular a una ritmo de 41 latidos por minuto. Se administró oxígeno, se estableció un acceso IV y se colocaron los cables del marcapasos transcutáneo en el tórax del paciente, luego se indujo el manejo de las guías publicadas. Resultados: El electrocardiograma mostró un ritmo idioventricular a una frecuencia de 41 latidos por minuto que se resolvió a un ritmo sinusal normal después del tratamiento. Conclusiones: Se debe realizar una evaluación cardiovascular completa y rápida en todos los pacientes que se presentan al departamento de emergencias después de una picadura de abeja, y se deben seguir las pautas publicadas sobre el manejo de la bradicardia y la anafilaxia para lograr resultados exitosos.
