Are the recommendations from three-dimensional gait analysis associated with better postoperative outcomes in patients with cerebral palsy?

This study was performed to check if recommendations based on three-dimensional gait analysis (3DGA) are associated with better postoperative outcomes in patients with cerebral palsy (CP). Thirty-eight patients who underwent orthopedic surgery and assessment at the Gait Analysis Laboratory were evaluated retrospectively. The patients were divided in four groups according to the agreement between the recommendations from gait analysis and the procedures actually carried out. Fifteen patients with diplegic spastic cerebral palsy and indication for orthopedic surgery to improve walking - and whose surgical intervention was postponed - were also included in the study as a control group. Fourteen gait parameters recorded before and after treatment, were included in the statistical analysis. No gait improvement was noted in the control group or inh patients on whom no procedures recommended by the gait exam were performed (agreement of 0%). In the other groups, agreements averaged 46.71%, 72.2%, and 100%, respectively. Improvement of gait parameters after treatment was observed in these groups, with more significant values directly related to increased agreement percentage. Therefore, in this study the patients whose treatment matched the recommendations from three-dimensional gait analysis showed a more significant improvement in walking. (c) 2008 Elsevier B.V.

Language impairment in euthymic, elderly patients with bipolar disorder but no dementia

Background: Neurocognitive impairment is known to occur in euthymic bipolar patients, but language alterations have not been thoroughly investigated. The aim of this study is to examine the performance in language tests of a sample of elderly patients with bipolar disorder. Methods: We studied 33 eurthymic elderly patients with bipolar disorder but no dementia and 33 healthy individuals, matched for age and education, who were compared in terms of their CAMCOG global score and its subitems. Results: The scores obtained in language-related abilities for patients and controls, respectively, were: language (total): 27.3 (1) and 28.5 (1), p < 0.0001)comprehension: 8.6 (0.5) and 8.9 (0.3), p = 0.006; production: 18.7 (1) and 19.6 (0.9), p = < 0.0001; abstraction: 6.8 (1.1) and 7.3 (0.7), p = 0.016; verbal fluency: 16.3 (4.3) and 19.6 (4.1), p = 0.003. Conclusion: A mild but significant impairment in language-related ability scores was detected when comparing patients and controls.

High frequency of submicroscopic chromosomal imbalances in patients with syndromic craniosynostosis detected by a combined approach of microsatellite segregation analysis, multiplex ligation-dependent probe amplification and array-based comparative genome hybridisation

We present the first comprehensive study, to our knowledge, on genomic chromosomal analysis in syndromic craniosynostosis. In total, 45 patients with craniosynostotic disorders were screened with a variety of methods including conventional karyotype, microsatellite segregation analysis, subtelomeric multiplex ligation-dependent probe amplification) and whole-genome array-based comparative genome hybridisation. Causative abnormalities were present in 42.2% (19/45) of the samples, and 27.8% (10/36) of the patients with normal conventional karyotype carried submicroscopic imbalances. Our results include a wide variety of imbalances and point to novel chromosomal regions associated with craniosynostosis. The high incidence of pure duplications or trisomies suggests that these are important mechanisms in craniosynostosis, particularly in cases involving the metopic suture.

Combination micrografting and tattooing in the reconstruction of eyebrows of patients with craniofacial clefts

The absence of an eyebrow, either partial or total, has been observed in patients with craniofacial clefts, such as the Tessier 9 to 13 cleft. Several techniques have been used to improve the appearance of the region, such as island scalp flaps and scalp strip grafting, with limited or marginally satisfactory aesthetic results. The authors report 2 patients with craniofacial clefts in whom a novel technique combining 2 separate surgical approaches, micrografting and tattooing, was used. The use of micrografting with single or double hair units, properly angulated, produces natural-looking and satisfactory results with a minimum of morbidity. Excellent volume and appearance of the eyebrow may be achieved in a single session using this technique. Tattooing performed subsequently over the microimplanted hairs provides the illusion of greater density to the eyebrow, resulting in an appearance closer to normal.
