Candida infection associated with a solitary mycotic common iliac artery aneurysm.

We report on a case of an isolated common iliac artery aneurysm infected by Candida albicans. To our knowledge, only one other case of this condition has been reported. The patient, a 49-year-old man with diabetes mellitus and a history of fungal urinary tract infections, had recurrent right knee pain and swelling. The knee effusion grew C albicans. Mild right hydronephrosis and a 4.6-cm aneurysm of the right common iliac artery without involvement of the aorta or iliac bifurcation was revealed by means of a computed tomography scan. The aneurysm wall was inflammatory, and there was associated purulence at the time of operation. The right ureter was densely adherent to the anterior aspect of the aneurysm, but could be palpated and dissected free because of a ureteral stent that was placed before the surgical incision. The aneurysm was resected, and the proximal and distal margins were oversewn without graft placement. C albicans was found in the resected aneurysm. The patient recovered without limb-threatening ischemia or claudication, but the distance he could walk remained limited because of right knee symptoms. The aneurysm may have formed by direct extension of infection from the right ureter or by hematogenous or lymphatic spread. This case raises interesting issues about operative strategies and etiology.

Pediatric-based assessment: children with school problems.

Twenty-one children with school problems underwent pediatric assessment within a university hospital primary care clinic. Assessment included history-taking facilitated by parent and teacher questionnaires, physical examinations, vision and hearing screening and neurodevelopmental examination. For 11 of the children, psychoeducational assessment was also obtained. Parent and school personnel were interviewed 2 to 6 months following assessment to determine implementation rates for recommendations. Overall, 66% of parent recommendations were implemented, including 72% of medical, 58% of mental health and 64% of educational recommendations. Seventy-two percent of school recommendations were implemented. Interdisciplinary evaluation as compared to pediatric-based assessment alone resulted in a greater number of recommendations generated (p less than .05) and a higher percentage of school recommendations implemented (p less than .01). Implementation rates for school recommendations were greater for young children (p less than .01). This study supports the usefulness of pediatric-based assessments for school problems and documents the advantages of an interdisciplinary approach to such children.

Structural basis of motility in the microtubular axostyle: implications for cytoplasmic microtubule structure and function.

The gross morphology of the protozoan microtubule axostyle of Saccinobaculus ambloaxostylus can now be described in macromolecular detail. The left-handed coil of the axostyle is seen to be dependent upon the asymmetry inherent in the constituent microtubules as expressed by the specific array of linkages between microtubules and by a possible tendency for microtubules to coil into left-handed helices. The laminated sheets of microtubules are not aligned parallel to the long axis of the organelle, but become increasingly tilted off-axis as one descends through the sheets of microtubules from the convex to the concave surface of the axostyle. Fine-structural analysis of the axostyle indicates similarities of the linkages to dynein. The potential loci of the force-generating protein(s) are discussed as well as implications of the axostyle's structure on general microtubule function.
