Background: Scrotal pain in the emergency department (ED) should be evaluated rapidly for sources that may cause irreversible testicular ischemia.

Objectives: This case report discusses a patient presenting with a large inguinal hernia causing testicle ischemia.

Case report: A 48-year-old man with a 1-year history of a large right-sided indirect inguinal hernia was transferred to the ED from the ultrasound laboratory after the patient experienced acute onset of severe right-sided testicular pain. The radiologist urgently called the attending emergency physician to notify him of ultrasound findings that showed compromised vascular flow to the right testicle. Urology and General Surgery were consulted immediately. The patient was placed in a supine position and reduction of the large hernia was attempted. After approximately 15 min of manual pressure, the herniated bowel was reduced back into the abdominal cavity and the patient experienced immediate relief of his symptoms.

Conclusions: Scrotal ultrasound was repeated, and vascular flow to his right testicle was found to be re-established. This case highlights a rare presentation of acute onset of testicular ischemia caused by vascular compression from a large indirect inguinal hernia in an adult male.

Background: A wandering spleen, defined as a spleen without peritoneal attachments, is a rare entity characterized by splenic hypermobility due to laxity or maldevelopment of the supporting splenic ligaments. Patients with a wandering spleen may be asymptomatic, or may present with a palpable mass in the abdomen, or with acute, chronic, or intermittent symptoms due to torsion of the wandering spleen. Because early clinical diagnosis is difficult, imaging modalities play an important role in the diagnosis. Treatment should be planned according to the vitality of the spleen.

Case report: A 22-year-old woman presented with an acute abdomen that was found to be due to a wandering spleen with 720° anti-clockwise torsion around the pedicle.

Conclusions: Splenectomy is advocated in the presence of torsion, splenic vein thrombosis, or splenic infarction. Conversely, when a viable wandering spleen is found at laparotomy, detorsion with splenopexy is preferred.

Background: The Centers for Disease Control (CDC) recommends universal human immunodeficiency virus (HIV) testing for patients aged 13-64 years in health care settings where the seroprevalence is>0.1%. Rapid HIV testing has several advantages; however, recent studies have raised concerns about false positives in populations with low seroprevalence.

Study objectives: To determine the seroprevalence of HIV in our Emergency Department (ED) population, understand patient preferences toward rapid testing in the ED, and evaluate the performance of a rapid oral HIV test.

Methods: A serosurvey offered oral rapid HIV 1/2 testing (OraQuick ADVANCE, Bethlehem, PA) to a convenience sample of 1348 ED patients beginning August 2008. Subjects declining participation were asked to complete an opt-out survey.

Results: 1000 patients were tested. Twelve had positive results (1.2%), including one who had newly diagnosed HIV infection; 988 patients tested negative. Of these, 335 (33.3%) had never been tested; 640 had prior history of a negative HIV test. No false-positive rapid HIV results were detected; 98.7% received the results of their preliminary HIV test, including 100% of those who tested positive. Most subjects who declined testing cited either a recent negative HIV test (160/348) or low perceived risk (65/348). A minority cited a concern regarding their privacy (11/348) or that the test might delay their treatment (7/348).

Conclusions: The seroprevalence estimate of 1.2% was above the rate recommended by the CDC for routine universal opt-out testing in our study population. The acceptance rate of rapid HIV testing and the percentage of patients receiving results approximated other recent reports.
