PURPOSE To describe the morphologic alterations in ultrasound biomicroscopy (UBM) present in peripheral vitreoretinal toxocariasis. METHODS An observational prospective study of case series. Fifteen eyes of 15 patients with clinical and laboratory diagnosis of peripheral vitreoretinal toxocariasis were enrolled. The patients were submitted to UBM examination of the region corresponding to the...

The solitary pulmonary nodule (SPN) is frequently encountered on chest imaging and poses an important diagnostic challenge to clinicians. The differential diagnosis is broad, ranging from benign granulomata and infectious processes to malignancy. Important concepts in the evaluation of SPNs include the definition, morphologic characteristics via appropriate imaging modalities, and the calculati...

Chronic lymphocytic leukemia (CLL) and hairy cell leukemia (HCL) are two common chronic lymphoproliferative disorders, each having characteristic clinical, morphologic, and immunologic features. Phenotypically, CD5 reactivity in CLL and C D l l c (Leu-M5) reactivity in HCL have characterized these two leukemias among B-cell disorders. In this study, we report 14 cases of a novel chronic lymphop...

We found oral stromal avascular corneal opacities in 128 eyes of 75 beagles from 497 studied. There were three morphologic types that progressed in severity with time; nebular, racetrack, and white arc. Histochemical study of the earliest morphologic type (nebular) revealed neutral fats, cholesterol, phospholipids, and sometimes fatty acids both intracellularly and extracellularly. We found no ...

Tooth segmentation has an important role in computer-aided orthodontics. However, fine segmentation results remain difficult to obtain because of various tooth shapes, complex tooth arrangements, and especially, tooth-crowding problems. Most published approaches or commercial solutions in this area are either interaction-intensive or inaccurate, and thus, we propose a novel tooth segmentation a...

This is a morphologic study of 41 cases of dextrocardia for the purpose of clarifying terminology and evaluating the clinical import of the morphologic data. Dextrocardias are classified as dextroversion, mirror-image dextrocardia, and mixed dextrocardia. When the atrial septum does not identifv the atria, it was found possible to make the presumptive diagnosis of dextroversion or mirror-image ...

Session 5 of 2007 Workshop of the Society for Hematopathology/European Association for Haematopathology focused on therapy-related myeloid neoplasms. This report discusses the diversity and relevance of clinical, pathologic, and genetic features and provides an update on the pathogenesis of these disorders. We highlight common diagnostic issues such as the differentiation between therapy-relate...

The domestic dog varies remarkably in cranial morphology. In fact, the differences in size and proportion between some dog breeds are as great as those between many genera of wild canids. In this study, I compare patterns of intracranial allometry and morphologic diversity between the domestic dog and wild canid species. The results demonstrate that the domestic dog is morphologically distinct ...

The systematic status and the evolutionary biology of chub mackerel (Scomber japonicus) in the South West Atlantic Ocean is confusing with an unknown degree of genetic differentiation and reproductive isolation between units. Simultaneous genetic and morphologic analyses were made on 227 fish collected from two areas of the South West Atlantic Ocean and one from the Mediterranean Sea. The genet...

Statistic approaches in speech technology, either based on statistical language models, trees, hidden Markov models or neural networks, represent the driving forces for the creation of language resources (LR), e.g. text corpora, pronunciation lexica and speech databases. This paper presents the system architecture for rapid construction of morphologic and phonetic lexica for Slovenian language....
