A 10-month-old boy, with congenital deafness and blindness associated with chromosomal deletion [46XY, del(13)(q32)], presented with intractable ascites 9 months after ventriculo-peritoneal shunting for congenital hydrocephalus. Revision of the ventriculo-atrial shunt resulted in shunt failure 1 month later. External ventricular drainage revealed(More)
The ability of non-human primates to follow the gaze of other individuals has recently received much attention in comparative cognition. The aim of the present study was to investigate the emergence of this ability in a chimpanzee infant. The infant was trained to look at one of two objects, which an experimenter indicated by one of four different cue(More)
A healthy 61-year-old woman with no antecedent trauma presented with a 10-year history of a slowly growing, painless mass in the right planta. She could not comfortably wear her right shoe. She did not complain of tenderness. The mass was elastic and hard, and was located in the subcutaneous tissue. The overlying skin was not thinned or discolored.(More)
Purpose: Detection of early CT signs of infarct in non- enhanced CT image is mandatory in patients with acute ischemic stroke. Loss of the gray-white matter interface at the lentiform nucleus or the insular ribbon has been an important early CT sign of acute cerebral infarction, which affects decisions on thrombolytic therapy. However, its detection is(More)
OBJECTIVE The purpose of this study was to evaluate the usefulness of z-score mapping method on neuroradiologists' performance in quantification of the extent of hypoattenuation regions of hyperacute stroke on unenhanced computed tomographic (CT) images by using the Alberta Stroke Programme Early CT Score system. METHODS Twenty-one patients with(More)
We examined and identified fungi flora found growing on two human cadavers. The main isolate colonized on the surfaces of the skin and bones was morphologically identified as Eurotium repens. The genus Eurotium usually inhabits soil and exhibits osmophilic properties. Because the cadavers contained abundant organic materials, Eurotium species formed(More)
The incidence of intracranial aneurysms in childhood is rare, especially in infancy. Spontaneous thrombosis of a cerebral aneurysm in a child is very rare, particularly in a non-giant aneurysm. We report a case of a 1-month-old girl with a distal anterior cerebral artery aneurysm which disappeared spontaneously after subarachnoid hemorrhage and reappeared 6(More)
RATIONALE AND OBJECTIVES Computed tomography (CT) plays a crucial role in early assessment of patients with traumatic brain injury (TBI). Marshall and Rotterdam are the mostly used scoring systems, in which CT findings are grouped differently. We sought to determine the scoring system and initial CT findings predicting the death at hospital discharge (early(More)
We present a practical case in which the fungi have contributed to the estimation of postmortem interval of the cadaver. A 71-year-old man wearing a shirt and pants was found dead at the bottom of an open well about 6m below the ground in his garden. Externally the face was dotted with colonies of white fungi, which was devoid of dipteran larvae and other(More)
RATIONALE AND OBJECTIVES The purpose of this study was to develop a z-score mapping method on the basis of a voxel-by-voxel analysis to visualize hypoattenuation areas of hyperacute stroke on unenhanced computed tomographic (CT) images. MATERIALS AND METHODS The algorithm of the developed method consisted of five main steps: anatomic standardization, the(More)
