IntroductionAnisakidosis, human infection with nematodes of the family Anisakidae, is caused most commonly by Anisakis simplex. Acquired by the consumption of raw or undercooked marine fish or squid, anisakidosis occurs where such dietary customs are practiced, including Japan, the coastal regions of Europe and the United States. Rupture of the spleen is a relatively common complication of trauma and many systemic disorders affecting the reticuloendothelial system, including infections and neoplasias. A rare subtype of rupture occurring spontaneously and arising from a normal spleen has been recognized as a distinct clinicopathologic entity. Herein we discuss the case of a woman who presented to our institution with appendicitis secondary to Anisakis and spontaneous spleen rupture.Case presentationWe report the case of a 53-year-old Caucasian woman who presented with hemorrhagic shock and abdominal pain and was subsequently found to have spontaneous spleen rupture and appendicitis secondary to Anisakis simplex. She underwent open surgical resection of the splenic rupture and the appendicitis without any significant postoperative complications. Histopathologic examination revealed appendicitis secondary to Anisakis simplex and splenic rupture of undetermined etiology.ConclusionsTo the best of our knowledge, this report is the first of a woman with the diagnosis of spontaneous spleen rupture and appendicitis secondary to Anisakis simplex. Digestive anisakiasis may present as an acute abdomen. Emergency physicians should know and consider this diagnosis in patients with ileitis or colitis, especially if an antecedent of raw or undercooked fish ingestion is present. Spontaneous rupture of the spleen is an extremely rare event. Increased awareness of this condition will enhance early diagnosis and effective treatment. Further research is required to identify the possible risk factors associated with spontaneous rupture of the spleen.

resuMenFundamento. Estudiar el número de pacientes diagnosticados de ictus en el servicio de urgencias hospitalario de un hospital de primer nivel y la proporción de estos pacientes que finalmente eran pseudoictus, así como describir y analizar las variables que pueden ayudar en el diagnóstico diferencial en los servicios de urgencias hospitalarios.Método. Estudio prospectivo de 9 meses. Se incluyeron todos los pacientes valorados en el servicio de Urgencias e ingresados con el diagnóstico de ictus. Se analizaron diversas variables clínicas que incluían la historia previa, la historia del evento actual, el examen físico general y neurológico y la clasificación del NIHSS y de la Oxforshire Community Stroke. El diagnóstico final se realizó por un panel de expertos con acceso a las características clínicas, estudios de imagen y otras pruebas. El análisis univariante y multivariado determinó las características que ayudan a distinguir los ictus de los pseudoictus.resultados. Se registraron 144 casos de ictus; la muestra final la conformó 140 pacientes. El diagnóstico final fue de ictus en 103 de 140 (73,6%) y de pseudoictus en el resto. Once variables predecían el diagnóstico en pacientes que se presentaban con sospecha de ictus: la edad superior a 70 años (p=0,012), una clasificación del NIHSS > 5, lograr una clasificación clínica (p=0,019) capaz de determinar el comienzo exacto (p=0,000), hallazgos vasculares anormales (p=0,014), desviación de la mirada (p=0.042), pérdida de la visión (p=0,052) y reflejo plantar extensor (p=0,025) favorecían el diagnóstico de ictus, mientras que las crisis comiciales (p=0,029), los síntomas neurológicos no congruentes con el territorio vascular (p=0,022) y los hallazgos anormales en otros sistemas (p=0,14) favorecían el diagnostico de pseudoictus.conclusión. Los pseudoictus constituyeron un tercio de los pacientes ingresados desde el servicio de Urgencias como ictus siendo la etiología muy variada. Lograr una historia clínica adecuada y un examen físico preciso es de gran importancia y puede ayudar a facultativos menos experimentados.Palabras claves. Pseudoictus. Ictus. Diagnóstico. abstract background. To study the number of patients diagnosed with a stroke in the emergency service of a first level hospital and the proportion of these patients who were finally stroke mimics, as well as to describe and analyze the variables that can help in differential diagnosis in hospital emergency services.

While elderly patients account for only 10-12% of all trauma victims, they consume 25% of trauma-related health care resources, with higher rates of mortality and complication. Presently described is the case of an elderly patient who presented to the emergency department (ED) following mild thoracic trauma, with previous history of gastric pull-up surgery. The patient had consulted another facility 48 hours earlier and was prescribed analgesia and x-ray follow-up for a mechanical fall and pain in the lower rib cage. At arrival, the patient complained of increasing dyspnea and pain at the right hemithorax. X-ray showed right hemithorax effusion, and contrast computed tomography (CT) demonstrated a large amount of contrast filling the pleural space and a relatively small point of gastric pull-up rupture in the stomach. The patient was referred to the cardiothoracic unit, but was unresponsive upon arrival and died. The aim of the present report was to raise the index of clinical suspicion of traumatic rupture of the gastric pull-up following traumatic chest injury, and to affirm that contrast CT should be the gold standard for diagnosis.
