Special education teachers for visually impaired students rely on tools such as raised-line maps (RLMs) to teach spatial knowledge. These tools do not fully and adequately meet the needs of the teachers because they are long to produce, expensive, and not versatile enough to provide rapid updating of the content. For instance, the same RLM can barely be used during different lessons. In additio...

Sperm whales (Physeter macrocephalus) produce multipulsed clicks with their hypertrophied nasal complex. The currently accepted view of the sound generation process is based on the click structure measured directly in front of, or behind, the whale where regular interpulse intervals (IPIs) are found between successive pulses in the click. Most sperm whales, however, are recorded with the whale ...

DEFINITION Cardiofaciocutaneous (CFC) syndrome is a relatively rare genetic disorder first described by Reynolds et al. in 1986 based on the observation of eight unrelated patients with very similar facial appearance characterized by unusually sparse, brittle, curly hair, large head (macrocephaly), a prominent forehead, and abnormal narrowing of the sides of the forehead (bitemporal constrictio...

We describe a sib pair with craniofacial anomalies, micrognathia, Mobius sequence, generalised myopathy, relative macrocephaly, and developmental delay. They appear to have the Carey-Fineman-Ziter syndrome (MIM 254940), which has been reported in only four children, a sib pair and two sporadic cases. This report on an additional affected brother and sister pair supports autosomal inheritance as...

INTRODUCTION: Congenital hydrocephalus, the most common cause of macrocephaly, is usually treated with ventriculoperitoneal (VP) shunting. Despite shunting, changes to the overlying cranial bones cause calvarial expansion and distortion. Reduction cranioplasty can be performed to approach proper cranial size, shape, and cephalocranial proportion. However, consistent results are difficult to ach...

We present an infant with true trisomy 22. Mosaicism is ruled out by the finding of a 47,XX, +22 karyotype in all cells analysed originating from two embryonic germ layers. The physical findings are consistent with the previously noted features including developmental delay, ear abnormalities, micrognathia, clefting, and congenital heart disease. The patient is the first described with macrocep...

PURPOSE To identify a pattern of findings on CT or MR of the brain in glutaric acidemia type I typical enough to permit a correct diagnosis. METHODS Clinical history and findings and brain CT and MR results in 59 previously reported patients (MR in 12) and in 5 new patients (all examined with MR and 3 also with CT) were reviewed. RESULTS In half the patients macrocephaly was present, and in...

Megalencephalic leukoencephalopathy with subcortical cysts is a rare leukodystrophy that is characterized by macrocephaly and a slowly progressive clinical course. It is one of the most commonly reported leukoencephalopathies in Turkey. Mutations in the MLC1 gene are the main cause of the disease. We report two patients with megalencephalic leukoencephalopathy with subcortical cysts with confir...

Received June 2008 Accepted September 2008 INTRODUCTION Neurofibromatosis is an autosomal dominant progressive disorder with an incidence of approximately 1 in 3000 live births.(1) Its recognized features include hyperpigmented skin lesions (cafe-au-lait spots), neurofibromas, iris hamartomas, macrocephaly, central nervous system tumors, defects of the skull and facial bones, and vascular lesio...

We report three new mutations in PTEN, the gene responsible for Cowden disease in five patients with Bannayan-Riley-Ruvalcaba syndrome from three unrelated families. This finding confirms that Cowden disease, a dominant cancer predisposing syndrome, and Bannayan-Riley-Ruvalcaba syndrome, which includes macrocephaly, multiple lipomas, intestinal hamartomatous polyps, vascular malformations, and ...
