Article: An unusual case of persistent extrinsic bronchial compression.
Maya Vallabhaneni, Ritwick Agrawal, Charles A Read[show abstract] [hide abstract]
ABSTRACT: Bronchomalacia is defined as diffuse or segmental bronchial weakness and easy compressibility. We present a rare case of a 67-year-old man with chronic cough as a consequence of focal bronchomalacia caused by persistent extrinsic compression of the left lower lobe bronchus by the descending aorta and the left lower lobe branch of the pulmonary artery. Focal bronchomalacia discovered during adulthood is most often acquired and can be attributed to extrinsic compression by abnormal blood vessels due to hypertension and lung transplantation or to bronchial disease processes. The natural history of bronchomalacia is typically progressive.Journal of bronchology & interventional pulmonology. 01/2010; 17(1):93-4. -
Article: Live three-dimensional echocardiography in evaluation of Alfieri mitral valve repair a case report.
[show abstract] [hide abstract]
ABSTRACT: Echocardiography plays a significant role in the evaluation of mitral valve repair. Three-dimensional(3D) echocardiography provides surgeon' views not obtainable by two-dimensional echocardiography. We report the live 3D echocardiographic evaluation of Alfieri mitral valve repair.Echocardiography 03/2008; 25(2):214-6. · 1.24 Impact Factor -

Article: Relating binocular and monocular vision in strabismic and anisometropic amblyopia.
[show abstract] [hide abstract]
ABSTRACT: To examine deficits in monocular and binocular vision in adults with amblyopia and to test the following 2 hypotheses: (1) Regardless of clinical subtype, the degree of impairment in binocular integration predicts the pattern of monocular acuity deficits. (2) Subjects who lack binocular integration exhibit the most severe interocular suppression. Seven subjects with anisometropia, 6 subjects with strabismus, and 7 control subjects were tested. Monocular tests included Snellen acuity, grating acuity, Vernier acuity, and contrast sensitivity. Binocular tests included Titmus stereo test, binocular motion integration, and dichoptic contrast masking. As expected, both groups showed deficits in monocular acuity, with subjects with strabismus showing greater deficits in Vernier acuity. Both amblyopic groups were then characterized according to the degree of residual stereoacuity and binocular motion integration ability, and 67% of subjects with strabismus compared with 29% of subjects with anisometropia were classified as having "nonbinocular" vision according to our criterion. For this nonbinocular group, Vernier acuity is most impaired. In addition, the nonbinocular group showed the most dichoptic contrast masking of the amblyopic eye and the least dichoptic contrast masking of the fellow eye. The degree of residual binocularity and interocular suppression predicts monocular acuity and may be a significant etiological mechanism of vision loss.Archives of Ophthalmology 07/2006; 124(6):844-50. · 3.71 Impact Factor
