Craniofacial morphology and occlusal pattern are evaluated in 71 subjects having impaired breathing as diagnosed by an otolaryngologist, and in an equal number of controls. The impaired group demonstrate characteristic combinations of craniofacial deformities and malocclusions, with the younger individuals demonstrating a lesser expression of malocclusion progression and morphologic deformities...

S everal investigators have shown the flow patterns and morphologic characteristics of perforator veins in healthy subjects and in patients with chronic venous disease (CVD). The complex nature of CVD, having many different factors associated with disease severity and deterioration, has made it difficult to elucidate the role of perforator vein incompetence. In this article, many of the importa...

Triatoma brasiliensis is composed of at least four geographic populations (brasiliensis, melanica, macromelasoma, and juazeiro) that have distinct chromatic, morphologic, biologic and ecologic patterns, and genetic composition. Reciprocal crosses between all pairwise combinations were carried out in order to evaluate the genetic and reproductive compatibility of these four populations. The F1 i...

PURPOSE Current diagnostic imaging modalities for human bronchial airways do not possess sufficient resolution and tissue penetration depth to detect early morphologic changes and to differentiate in real-time neoplastic pathology from nonspecific aberrations. Optical coherence tomography (OCT) possesses the requisite high spatial resolution for reproducible delineation of endobronchial wall pr...

T his report introduces and describes a method of cephalometric evaluation for in&viduals based on their own particular morphologic and morphogenetic facial patterns. References to statistical population standards are not required. The purpose of the procedure is to analyze the nature of anatomic fit among the different bones of the craniofacial complex of one subject at any age and through tim...

In this preliminary biometric study of the calcareous nannofossil species Chiasmolithus expansus, Chiasmolithus oamaruensis, and Chiasmolithus altus from the upper middle Eocene to lower Oligocene of Sites 647 and 748, we document a complete gradation of forms among all three species. Chiasmolithus oamaruensis has significantly higher morphologic variance than the other species. The Chiasmolith...

BACKGROUND AND PURPOSE Whether Alzheimer disease (AD) represents exaggerated aging rather than a disease is controversial. Data about the effects of normal aging on the human brain are essential for clarifying this issue; however, whether coherent common patterns of regional morphologic brain changes emerge in the normal aged brain is unclear. Clarification of regional morphologic changes in th...

Abstract Follicular dendritic cell (FDC) sarcoma, a rare tumor of FDCs, poses diagnostic challenge due to its myriad morphologic and architectural patterns. We present unique case extra-nodal FDC sarcoma occurring in 28-year-old gentleman who presented with multiple pelvic, peritoneal retroperitoneal soft tissue, axial skeletal lesions. The was composed islands trabeculae epithelioid cells inte...
