The use of focused abdominal sonography for trauma (FAST), which detects free fluid in the abdomen and pelvis, for the assessment of blunt abdominal trauma is gaining acceptance worldwide and has been described extensively in the general medical literature. The precise application of this technique in pediatric patients, however, has yet to be established. The aim of this study was to assess the utility of FAST in pediatric trauma patients by comparing the results of this technique with those of CT and explorative laparotomy (ELAP). ⋯ FAST is an effective tool in screening pediatric trauma patients for blunt abdominal trauma.

Chronic secondary mesenteroaxial gastric volvulus associated with hypertrophic pyloric stenosis has rarely been mentioned in the general medical literature. We report the case of a 2-month-old boy whose clinical symptoms, which included distension of the stomach and projectile vomiting, suggested the diagnosis of hypertrophic pyloric stenosis but who was later diagnosed with chronic secondary mesenteroaxial gastric volvulus. Sonographic examination revealed findings consistent with a rotated stomach, and subsequent plain chest radiography demonstrated a left diaphragmatic eventration. ⋯ Surgery was performed, and the boy recovered well. A follow-up sonographic examination performed 3 months post-operatively revealed no abnormalities. This case demonstrates that primary or secondary gastric volvulus, although rare in children, should be considered in the differential diagnosis of pediatric patients with a history of vomiting.

Case Reports
Partial preoperative reduction of inguinal hernia through compression with an ultrasound transducer.
Sonography and CT are effective tools in early diagnosis of asymptomatic inguinal hernia. Sonography can be used not only for the diagnosis of hernia but also for its treatment. Real-time sonographically guided hernia reduction may avoid tissue damage that can arise from misguided compression. We report a unique case in which an incarcerated omental hernia in a 50-year-old woman was diagnosed and subsequently reduced via compression with an ultrasound transducer.

The objective of this study was to investigate whether the retrobulbar hemodynamics in the ophthalmic (OA), posterior ciliary (PCA), central retinal (CRA), and vertebral (VA) arteries are affected in migraineurs without aura. ⋯ The retrobulbar circulation and flow hemodynamics in the left VA may be altered in both headache and headache-free periods in migraineurs without aura. The differences found between migraineurs and control subjects may implicate autonomic dysfunction in migraineurs.

Case Reports
Pseudoaneurysm of the dorsalis pedis artery: color Doppler sonographic and angiographic findings.
Pseudoaneurysm of the dorsalis pedis artery is an uncommon condition that is usually caused by a traumatic injury or an iatrogenic intervention. The patient usually complains of an enlarging painless, pulsatile mass. A tentative diagnosis may be made by palpation of the pulsatile mass and detection of an associated systolic bruit. ⋯ The patient was treated with ligation of the artery and resection of the pseudoaneurysm. He recovered well after surgery and remained free of symptoms 3 months postoperatively. We believe that color Doppler sonography should be the procedure of choice for use in diagnosing pseudoaneurysms; arteriography can then be used to evaluate the alternative blood supply before surgery is undertaken.
