PURPOSE: Classically air in the portal vein has been detected on plain radiography, but computed tomography and ultrasonography have been shown to be more sensitive. We report a case of air in the PV in a 10-day-old infant with pneumatosis intestinalis with its ultrasonographic and Doppler findings. MATERIAL AND METHODS: The patient was a 10-day-old infant born by cesarean section at 41 weeks. Simple abdomen film revealed branching pattern of radiolucent air shadows within the contour of liver, gas distention of bowel loops and thickenod bowel walls with lincar intraluminal air shadows in abdomcn, suggesting neerotizing enterocolitis. So we performed Doppler ultrasonography. RESULTS: Ultrasonography showed branching pattern of hyperechogenic dots along the lumen of left portal vein. The color Doppler study revcaled an aliasing duo to increased velocity and whirling pattern of blood flow, and the Duplex Doppler spectral display showed sharp, vertical bidirectional spikes by air in portal vein. CONCLUSION: Air in the portal voin can be easily diagnosed by the followign signs:hyperechogenic dots in the portal vein on ultrasonography and vertical, sharp bidirectional spikes superimposod on the usual Doppler tracing of the portal vein on Duplex ultrasonography.

The obstructive sleep apnea syndrome can occur due to various etiologies in children. In otherwise healthy children, adenotonsillar hypertrophy is the leading cause of childhood obstuctive sleep apnea. Obstructive sleep apnea caused by adenotonsillar hypertrophy can lead to a variety of symptoms and sequelae such as behavioral disturbance, enuresis, failure to thrive, developmental delay, cor pulmonale, and hypertension. So if obstructive sleep apnea is clinically suspected, proper treatment should be administered to the patient after diagnostic examinations. More than 80% improvement is seen in symptoms of obstructive sleep apnea caused by adenotonsillar hypertrophy in children after tonsillectomy and adenoidectomy. However, when it is impossible to treat the patient using surgical methods or residual symptoms remained after tonsillectomy and adenoidectomy, additional treatments such as weight control, sleep position change, and continuous positive airway pressure (CPAP), should be considered. This paper reports a case using weight control and Auto-PAP to control mild sleep apnea and snoring, which in long-term follow-up were not resolved after tonsillectomy and adenoidectomy for severe obstructive sleep apnea.

PURPOSE: We investigated the clinical characteristics of ocular trauma in the military for prevention and treatment application. METHODS: We retrospectively surveyed epidemiologic characteristics by investigating the medical records of 790 patients who were hospitalized in the Armed Forces Capital Hospital from January 1, 2001 to December 31, 2010 and investigated the prognostic factors that influenced visual outcome. RESULTS: Among the 790 patients with ocular trauma, 22.9% of the patients had an open injury and 77.1% had a closed injury. The most common cause of injury was sports-related ocular trauma (39%) and fatigue duty-related trauma (23.4%). The following 8 risk factors were considered poor prognostic factors: open injury, involved posterior segment, operation, initial visual acuity of 0.1 or less, corneal laceration, hyphema, RD, and intraocular foreign body. There was a significant correlation between the probability of poor visual outcome and the number of risk factors (correlation coefficient = -0.468, p < 0.0001). CONCLUSIONS: In the present study, the cause, characteristics and prognostic factor of military personnel's ocular injury were determined. The results can be useful in the prevention and management of ocular injury in the military.
