Chaotic behavior of a Galerkin model of a two-dimensional flow.

Chaotic behavior of a Galerkin model of the Kolmogorov fluid motion equations is demonstrated. The study focuses on the dynamical behavior of limit trajectories branching off secondary periodic solutions. It is shown that four limit trajectories exist and transform simultaneously from periodic solutions to chaotic attractors through a sequence of bifurcations including a periodic-doubling scenario. Some instability regimes display close similarities to those of a discrete dynamical system generated by an interval map.

Sternomastoid tumor of infancy (fibromatosis colli): diagnosis by aspiration cytology.

Sternomastoid tumor (SMT), as part of the spectrum of muscular torticollis, presents in infants as a discrete mass lesion in the neck, typically unassociated with neck torsion. We describe two patients who underwent fine needle aspiration (FNA) of their neck mass. The cytopathology of these aspirates was composed solely of a mixture of benign-appearing spindle cells and degenerating myofibers. Both infants showed a gradual disappearance of the mass without surgical intervention. We believe that FNA cytology is a diagnostic tool applicable to neonates. Additionally, in the proper clinical setting, aspiration cytology can be diagnostic of the clinicopathologic entity of SMT.

Immunohistochemical evidence for the vascular origin of primary adrenal pseudocysts.

Pseudocysts are the most common nonfunctioning cystic adrenal lesions associated with symptoms. We have studied tissue from two patients with large adrenal pseudocysts in whom no antecedent cause could be documented. Immunohistochemical examination of these formaldehyde-fixed paraffin-embedded tissues with antibodies directed against the major proteins of the basement membrane (laminin and type IV collagen) revealed intense linear staining surrounding the cystic spaces and at the compressed adrenal cortical/pseudocyst interface. These findings lead us to conclude that these lesions are vascular in nature and, therefore, closely related to the previously recognized adrenal cysts of endothelial origin.
