The multidisciplinary consensus on the classification of prenatal and postnatal urinary tract dilation (UTD classification system) was created to unify the language used to describe urinary tract dilation on antenatal and postnatal ultrasound examinations and thereby facilitate communication among providers and improve outcomes research. The background and new classification system are described in this review, with imaging examples. 相似文献

BackgroundThe objective of the study was to report on the main parameters of ocular biometry and Intraocular lens (IOL)power of patients attending a cataract surgical campaign in Eastern Ethiopia.MethodsThe study was a cross-sectional study on 765 eyes which were eligible for cataract surgery during a mass cataract surgical campaign conducted from April 04 to April 10, 2018 at Bisidimo Hospital, Eastern Ethiopia. Ocular biometric parameters were measured by automated keratorefractometer and Sonomed A-Scan (Model 300AP) using contact applanation method. Multiple linear regression analysis was done to determine association of ocular biometry components with socio demography of the study subjects.ResultsThe mean corneal curvature and anterior chamber depth (ACD, measured from corneal epithelium to lens) were found to be 7.61 mm and 2.88mm respectively. The mean axial length was estimated to be 22.98 mm. The mean refractive power of IOL was calculated to be 19.34D. The mean axial length in females was shorter than that of males by 0.24 (P - value = 0.01). The mean ACD in males was also larger than that of females by 0.1 (P - value = 0.001).ConclusionThis study provided a larger population based normative data on ocular biometry in Ethiopia. The female sex was a strong predictor of small axial length. Increasing age had no effect on axial length but was found to be a stronger predictor of shallow ACD. 相似文献

Zusammenfassung
Die Fremdk?rperaspiration stellt eine h?ufige Ursache für Atemnot und respiratorische Insuffizienz bei S?uglingen und Kleinkindern
zwischen 6 Monaten und 3 Jahren dar. R?ntgendichte Fremdk?rper bereiten bei Abbildung des gesamten Respirationstraktes keine
diagnostischen Schwierigkeiten. Nicht r?ntgendichte Fremdk?rper erfordern ein differenzierteres Vorgehen, wobei der erste
radiologische Schritt in einer konventionellen Thoraxaufnahme in In- und Exspiration bestehen sollte. Zus?tzliche Aufnahmen,
Durchleuchtungsuntersuchung und gegebenenfalls die Durchführung einer computertomographischen oder szintigraphischen Untersuchung
h?ngen vom Ergebnis der Thoraxaufnahme ab. H?ufigstes radiologisches Erscheinungsbild ist die einseitige exspiratorische Ventilstenose
mit überbl?hung des betroffenen Lungenabschnittes. Seltener finden sich Atelektasen, rezidivierende Pneumonien an identischer
Lokalisation und inspiratorische Ventilstenosen. Kombinationsbilder sind m?glich, selbst ein unauff?lliges Untersuchungsergebnis
kann eine Aspiration nicht ausschlie?en.

Recent technical advances in neurosonography continue broadening the diagnostic utility, sensitivity, and specificity of ultrasound for detecting intracranial abnormalities bed side. The clinical and functional applications of neurosonography have significantly expanded since the 1980s when transcranial Doppler sonography first allowed anatomic and hemodynamic delineation of the intracranial vessels through the thin temporal skull. In the past few years, contrast‐enhanced ultrasonography, elastography, 3D/4D reconstruction tools, and high‐resolution microvessel imaging techniques have further enhanced the diagnostic significance of neurosonography. Given these advances, a thorough familiarity with these new techniques and devices is crucial for a successful clinical application allowing improved patient care. It is essential that future neurosonography studies compare these advanced techniques against the current “gold standard” computed tomography and magnetic resonance imaging to assure the accuracy of their diagnostic potential. This review will provide a comprehensive update on currently available advanced neurosonography techniques. 相似文献

The influence of the combinations of oximes on the reactivating and therapeutic efficacy of antidotal treament of acute sarin poisoning was evaluated in this study. The ability of two combinations of oximes (HI-6 + trimedoxime and HI-6 + K203) to reactivate sarin-inhibited acetylcholinesterase and reduce acute toxicity of sarin was compared with the reactivating and therapeutic efficacy of antidotal treatment involving single oxime (HI-6, trimedoxime, K203) using in vivo methods. Studies determining percentage of reactivation of sarin-inhibited blood and tissue acetylcholinesterase in poisoned rats showed that the reactivating efficacy of the combination of oximes involving HI-6 and K203 is slightly higher than the reactivating efficacy of the most effective individual oxime in diaphragm and brain but the difference between them is not significant. The ability of combination of oximes involving HI-6 and trimedoxime to reactivate sarin-inhibited acetylcholinesterase roughly corresponds to the reactivating effects of the most effective individual oxime in blood as well as tissues. Moreover, both combinations of oximes were found to be as efficacious in the reduction of acute lethal toxic effects in sarin-poisoned mice as the most effective individual oxime. A comparison of reactivating and therapeutic efficacy of individual oximes showed that the oxime HI-6 is markedly more effective than the oxime K203 and trimedoxime. Based on the obtained data, we conclude that the antidotal treatment involving chosen combinations of oximes does not significantly influence the ability of the most effective individual oxime (HI-6) to reactivate sarin-inhibited rat acetylcholinesterase and to reduce acute toxicity of sarin in mice. 相似文献

We present here a few basic proposals for algorithms and procedures for imaging the paediatric genitourinary tract based on
initial discussion at a paediatric uroradiology symposium and proposals of the ESUR Paediatric Uroradiologic Guidelines Subcommittee.
These recommendations were developed in the light of new knowledge that might influence existing guidelines. Regional, individual
and local flexibility and variability should be preserved in order to make these recommendations applicable throughout Europe.
They should help standardize dedicated imaging not only in terms of a quality measure to ensure state-of-the-art patient care,
but also in forming a common basis for multi-institutional research. There is an urgent need for these guidelines in order
to advance our understanding of the subject and to gain evidence and improve imaging efficacy. Our session worked towards
establishing an agreement on imaging indications in common paediatric urological conditions, respecting the ALARA principle,
and patient safety and care, and taking into account state of the art knowledge and efficacy aspects. We started the task
with a reassessment of (1) imaging in urinary tract infection in infants and children, (2) postnatal imaging in mild-to-moderate
neonatal hydronephrosis, (3) how to perform voiding cystourethrography, and (4) procedural recommendations for paediatric
urosonography. This list is incomplete, and future recommendations will be developed, discussed and presented at forthcoming
meetings.

ABSTRACT An effective vehicle to change behaviors is entertainment education. To demonstrate entertainment education effects, researchers must first indicate that participants have been exposed to their program. Exposure to effective programs has been associated with increases in knowledge about program topics, attitude change, and self-efficacious perceptions. The purpose of this study was to develop and test a new exposure technique that accurately and precisely determines direct exposure levels to Ethiopia's Journey of Life. Overall, the study found very high listenership, storyline recall, liking of the program, and strong desire to change behavior while maintaining low error rates in terms of verbatim recall of storylines and reported listenership to a fictitious program. 相似文献

Streptococcus pneumoniae as a cause of cellulitis is rarely reported in children and adults. We report on an infant with facial cellulitis due to pneumococci and review already described cases since 1975. The main features of this infection, underlying diseases and problems of diagnostics and therapy are discussed. 相似文献
