Reduced posterior nasal cavity volume: A gender-specific neurodevelopmental abnormality in schizophrenia

Sarcoma of Nasal Cavity: A Case Report

This case report is a 65 year old woman from Kerman. Her main complian is nasal obstruction and recurrent nasal bleeding from five months ago. In clinical examination there was a large tumor in left nasal cavity. CT scaning revealed a large tumor in left nasal cavity and maxillary sinuse. The tumor is resected compeletely with negative safe margine by radical caldwell- luc approach. The origin ...

Reduced gray matter volume in schizophrenia.

BACKGROUND There is emerging evidence that gray matter (GM) is reduced in patients with schizophrenia. Information on the extent of global differences in the 3 principal supertentorial compartments is necessary for interpretation of regional effects. The relation of GM reduction to clinical status and neurocognition also requires examination. METHODS Magnetic resonance imaging, neurocognitive...

Is schizophrenia a neurodevelopmental disorder?

Neurodevelopmental risk factors in schizophrenia.

The authors review environmental and neurodevelopmental risk factors for schizophrenic disorders, with emphasis on minor physical anomalies, particularly craniofacial anomalies and dermatoglyphic variations. The high prevalence of these anomalies among schizophrenic subjects supports the neurodevelopmental theory of the etiology of schizophrenia, since they suggest either genetically or epigene...

Stereological analysis of cornu ammonis in prenatally stressed rats: a heuristic neurodevelopmental model of schizophrenia

Objective(s):The hippocampus has been implicated in pathophysiology of schizophrenia. Prenatal stress is a contributing risk factor for a wide variety of neuropsychiatric diseases including schizophrenia. This study examined long-term effects of prenatal restraint stress on the stereological parameters in the Cornu Ammonis (CA) of adult male rats as an animal model of schizophrenia. Materials ...
