OBJECTIVES Document patient choices and screening performance (false positive and detection rates) when three improved Down syndrome screening protocols were introduced coincidentally. METHOD Second-trimester 'triple marker' screening was expanded by adding second-trimester dimeric inhibin-A (four-marker), with or without first-trimester pregnancy-associated plasma protein-A (five-marker). Nu...

Nuchal translucency (NT) measurements in the first trimester screening between 11 and 14 weeks' gestation are regarded as a clear marker for aneuploidies. The presence of a thickened NT, even if the karyotype is normal, can be associated with structural abnormalities. Having an abnormal screening of NT, parents and physicians could face dilemma over abortion particularly in a case of IVF/ICSI f...

OBJECTIVE To evaluate the performance and cost efficacy of different first-trimester contingent screening strategies based on an initial analysis of biochemical markers. DESIGN Retrospective study. SETTING Swedish National Quality Register for prenatal diagnosis. POPULATION 35,780 women with singleton pregnancies. METHODS Serum values from first trimester biochemistry were re-analyzed i...

introduction measuring magnetic induction phase shift (mips) changes as a function of cerebral hemorrhage volume has the potential for being a simple method for primary and non-contact detection of the occurrence and progress of cerebral hemorrhage. our previous mips study showed that the intracranial pressure (icp) was used as a contrast index and found the primary correlation between mips and...

conclusion coil embolization showed successful outcomes in the treatment of intracranial aneurysms with a low complication rate. results immediately after the procedure, the total occlusion was seen in 76 (86.4%), subtotal occlusion in six (6.8%), and partial occlusion in six patients (6.8%). there was no significant relationship between the aneurysm size, aneurysm neck size, and location of th...

in recent years, the usefulness of intracranial pressure (icp) monitoring has been questioned in several reports for traumatic brain injury (tbi) management. therefore the needs of multidisciplinary groups of discussion of neurosurgeons and neurointensivists to update practical applications of icp in severe adult tbi has been advocated in many parts of the world. a consensus conference was held...

introduction: myelograghy is a process of instilling contrast medium to the subarachnoid space for evaluating the spinal column by radiography. there are various contrast solutions for different radiographic studies but not all of them are suitable for spinal column evaluation. conclusions: our subject recovered completely without any sequelae after receiving appropriate treatment in a multidis...

ABSTRACT Objectives: To evaluate the translucency, contrast ratio and masking ability of a translucent zirconia with different thicknesses. Methods: Disc shaped specimens (n= 3) 10 mm (Ø) x 1.5 mm, 1 0.7 (thickness) were manufactured simulating all-ceramic simplified restorations. Substrate discs 2; Ø: mm; thickness: 2 mm) simulated composite resin shades: A2 (positive control) C4; metal alloys...
