Background: Many suicidal and depressed patients are seen in emergency departments (EDs), whereas outpatient visits for depression remain high. Study objective: The primary objective of the study is to determine a relationship between the incidence of suicidal and depressed patients presenting to EDs and the incidence of depressed patients presenting to outpatient clinics. The secondary objective is to analyze trends among suicidal patients. Methods: The National Hospital Ambulatory Medical Care Survey and the National Ambulatory Medical Care Survey were screened to provide a sampling of ED and outpatient visits, respectively. Suicidal and depressed patients presenting to EDs were compared with depressed patients presenting to outpatient clinics. Subgroup analyses included age, sex, race/ethnicity, method of payment, regional variation, and urban verses rural distribution.

Early identification and treatment of neuroblastoma, the most common malignant solid tumor in infants, (Atkinson et al. AJR Am J Roentgenol. 1986;146:113-117; Nuchtern. Semin Pediatr Surg. 2006;15:10-16; Lanzkowsky. Manual of Pediatric Hematology and Oncology. 4th ed. Burlington, MA: Elsevier Academic Press; 2005:530-547) can improve prognosis of this illness. Benign emesis as an initial presentation of infantile neuroblastoma is rare (Isaacs. Fetal Pediatr Pathol. 2007;26:177-184). We report a case of a 17-day-old healthy male who presented to the emergency department with persistent, nonprojectile emesis after feedings. A diagnosis of nonresectable stage IV thoracoabdominal neuroblastoma with invasion to the spine was made. We concluded that oncological processes, such as neuroblastoma, should be included in the differential diagnosis of persistent emesis in the neonatal period. Emergency physicians may have the opportunity to detect neuroblastoma earlier by contemplating a broader differential diagnosis of a vomiting infant and initiating the appropriate workup in the emergency department.
