Optimal Window

Introduction: When a pneumothorax exists, free air should rise to the most nondependent region within the chest. Current ultrasound (US) examination methodologies may exclude visualization of these areas that may limit the sensitivity of the examination. This retrospective study uses computed tomography (CT) scans to precisely evaluate where free air within the thorax occurs and correlates this location with a presumably optimal US interrogation window. Methods: A total of 94 CT scans of patients with a pneumothorax in a single institution from December 2006 to January 2010 were examined. The borders and volumes of each pneumothorax were precisely measured by a radiologist. Logistic regression was used to determine the relationship between volume and location of intrapleural air at specified areas of the hemithorax. Sensitivities relating location of intrapleural air at a specific landmark and side of thorax were calculated. Results: All but 3 of the pneumothoraces extended to the sternum. In all, 83 patients demonstrated a pneumothorax between rib interspaces 3 and 6 (mean pneumothorax volume 300.4 mL, 95% confidence interval [CI] 217.4-383.3), and 11 patients did not (mean pneumothorax volume 4.5 mL, 95% CI 1.7-7.3; P < .0001). The cumulative sensitivity for the presence of intrapleural air at rib interspaces 3 to 6 along the sternal border was 88%. This was consistent regardless of the side of hemithorax (right 91% and left 86%). Conclusion: The CT scans demonstrate that intrapleural air most often collects along the mediastinum between ribs 3 and 6 on either side of the chest. Although no USs were performed in this retrospective study, one may infer that a parasternal approach along rib interspaces 3 to 6 is an easy and sensitive window to diagnose pneumothorax with US.

Abstract Introduction Retrograde transvenous obliteration (RTO) with the assistance of a balloon (BRTO) or a vascular plug (PARTO) is an established method for treating gastric varices (GVs) secondary to portal hypertension. Most of the available studies on RTO have used lipiodol along with sclerosing agents like ethanolamine oleate or sodium tetradecyl sulfate (STS). We evaluated the safety and efficacy of RTO for treating GVs using STS as a sclerosant without lipiodol. Materials and Methods Sixteen patients (nine men, age range 16–74 years) were included in this retrospective study. Twelve patients presented with acute bleeding, two with chronic bleeding, one with large varices without bleeding, and one with refractory hepatic encephalopathy (HE). BRTO was attempted in 14 patients and PARTO in 2 patients. The technical and clinical success and complications of RTO were studied. Results The RTO procedure was technically successful in 14 (14/16, 87.5%) patients, with 13 (13/14, 93%) obtaining clinical success. One patient died due to the early recurrence of bleeding. Three patients had minor intraprocedural complications. Conclusion Retrograde gastric variceal obliteration using STS is safe and technically feasible with high technical and clinical success and low complication rate.

Background Ventilator􀁖associated pneumonia (VAP) is anosocomial infection in patients who have received mechanicalventilation (MV), either by endotracheal intubation ortracheostomy, for more than 48 hours. YAP represents 80% ofall hospital􀁖acquired pneumonias. VAP incidence varies from5.1 %􀁖33.3%. The modified clinical pulmonary infection scoreis a criteria for diagnosing suspected YAP and typically includesradiographic evidence. YAP is associated with significantmorbidity and mortality.Objective To determine the relationship between chest x􀁖rayfindings and outcomes in children Mth suspected VAP.Methods This retrospective study was held in Dr. Kariadi Hospitalfrom January - December 2010. Data was collected from medicalrecords of pediatric ICU (PICU) patients with suspected VAP.Chest x􀁖ray findings and patient outcomes were recorded. X􀁖rayfindings were assessed by the on􀁖duty radiologist. Chi square testwas used for statistical analysis.Results Subjects were 30 children consisting of 14 males and 16females. Patient outcomes were 23 patients survived and 7 patientsdied. Chest x􀁖ray findings were categorized into the followinggroups and compared to patient survivability: diffuse infiltrates76.7% (OR􀁗0.694; P􀁗0.532; 95% CI 0.102 to 4.717), localhedinfiltrates 13.3% (OR􀁗4.200; P􀁗 0.225; 95% CI 0.470 t037.49),and no infiltrates 10% (OR􀁗 1.222; P􀁗 0.436; 95% CI 0.593 to0.926). None of the x􀁖ray findings had a significant correlationto patient outcomes.Conclusion There was no significant relationship between chestx􀁖ray findings and outcomes in children with suspected VAP.[Paediatr rndones. 2012;52:233-8].
