Quick radiological diagnosis is often needed in order to allow the clinicians to make a diagnosis. The purpose of this study was to measure examination time for radiology procedures before and after physical integration of a radiology unit in the ED. We retrospectively acquired data from the radiology information system and compared time from referral to end of radiological examination before and after physical integration of the radiology unit in the ED for 19,897 X-ray and 6,940 CT examinations. After integration examination time for X-ray examinations was reduced by 5 to 14 minutes (p<0.001). For CT head and chest examination time was reduced by 7 to 15 minutes (p<0.003) while examination time for CT abdomen was prolonged by 4 minutes (p=0.78).

Background: Asthma is a heterogeneous disease characterized by cough, wheeze and shortness of breath that vary in intensity and time with variable expiratory airflow limitation, associated with chronic airway inflammation. Aim of the study was to assess the usefulness of Peak Expiratory Flow Rate [PEFR] and oxygen saturation in determining severity of acute asthma, to measure objective change in PEFR and oxygen saturation following bronchodilator therapy and the role of chest X-rays in acute asthma.Methods: A prospective study of 50 children above 5 years with acute asthma who presented to the emergency department in a tertiary care hospital were included. PEFR and oxygen saturation before and after bronchodilator therapy was measured. Indication for chest X-rays, its clinical correlation and change in standard treatment of acute asthma based on X-ray reports was noted.Results: The mean PEFR and PEFR % of expected was lower in severe asthma when compared to moderate asthma and was statistically significant (p<0.001). The % of expected PEFR before salbutamol therapy was 48.78±14.36, which improved significantly to 67.13±14.22 after treatment (p<0.001). Oxygen saturation before and after salbutamol therapy was 94.96 ± 4.11 and 96.96±2.87 respectively with the change being significant (p value <0.001). Chest X-rays were performed in 12 (24%) children as per standard guidelines, of which 1(9%) was abnormal showing right basal consolidation. Chest X-ray correlated with clinical findings in 1 child and the findings on chest X-ray altered the ongoing treatment by addition of antibiotic.Conclusions: PEFR and oxygen saturation is useful in the emergency department to objectively assess the severity of acute asthma and the response to initial bronchodilator therapy. Chest X-rays are not routinely indicated in the standard treatment of acute asthma.

Set Up

Freeze-etching electron microscopy is currently one of the best methods for studying molecular organization of biological materials. Its application, however, is still limited by our imprecise knowledge about the perturbations of the original organization which may occur during quenching and fracturing of the samples and during the replication of fractured surfaces. Although it is well known that the preservation of the molecular organization of biological materials is critically dependent on the rate of freezing of the samples, little information is presently available concerning the nature and the extent of freezing-rate dependent perturbations of the original organizations. In order to obtain this information, we have developed a method based on the comparison of x-ray diffraction patterns of samples before and after freezing, prior to fracturing and replication.Our experimental set-up is shown in Fig. 1. The sample to be quenched is placed on its holder which is then mounted on a small metal holder (O) fixed on a glass capillary (p), whose position is controlled by a micromanipulator.

Aluminum-copper-silicon thin films have been considered as an interconnection metallurgy for integrated circuit applications. Various schemes have been proposed to incorporate small percent-ages of silicon into films that typically contain two to five percent copper. We undertook a study of the total effect of silicon on the aluminum copper film as revealed by transmission electron microscopy, scanning electron microscopy, x-ray diffraction and ion microprobe techniques as a function of the various deposition methods.X-ray investigations noted a change in solid solution concentration as a function of Si content before and after heat-treatment. The amount of solid solution in the Al increased with heat-treatment for films with ≥2% silicon and decreased for films <2% silicon.

Linear low density polyethylene (LLDPE) was chemically modified with grafting maleic anhydride (MAH) monomer on its backbone by melting blending. Nano-particles SiO2 was modified by cationic surfactant hexadecyl trimethyl ammonium bromide (CTAB) and anionic surfactant sulfosalicylic acid (SSA) and added to PE coating respectively. Measurement of membrane potential showed that the coating containing modified SiO2 nano-particles had characteristic of ion selectivity. The properties of the different coatings were investigated according to relative industrial standards. Experimental results indicated that PE coating with ion selectivity had better performances, such as adhesion strength, cathodic disbonding and anti-corrosion, than those of coating without ion selectivity. Crystal structure of the coatings before and after alkali corrosion was characterized by Fourier transform infrared spectra (FTIR) and X-ray diffraction (XRD). Structure of the coating without ion selectivity was damaged by NaOH alkali solution, causing mechanical properties being decreased. And the structure of the ion selective coatings was not affected.

Intraocular foreign bodies (IOFB) present differently depending on the type of material (wood, glass, metal) for the IOFB, extent of the injury, and location of the injury. IOFB and the injury can cause a perforation or penetration of the globe which can require more extensive treatment including surgery. Proper evaluation of the IOFB and injury can help to determine extent of the injury, the prognosis of the vision, and health of the eye before and after treatment but may be difficult for the physician depending on the view of the posterior chamber being compromised by media or simply by patient sensitivity. The extent of the injury may also prevent proper evaluation due to swelling, lacerations on the lids, or pain. Proper ophthalmic sonography can provide a quick evaluation of the globe for any IOFB in both the outpatient setting as well as emergency department setting. Evaluation via sonography may allow the physician to accurately diagnose and properly treat the patient to help restore and prevent further loss of vision.
