Prospective and Bidirectional Cross-Sectional Associations between Body Mass Index and Physical Activity following Liposuction: A Cohort Study.

Background: It has been speculated that the immediate decrease in body fat following liposuction may affect body composition by feedback mechanisms of body fat regain. Physical activity has both short- and long-term impacts on health. Although the lay public often associates higher levels of physical activity with body fat distribution changes, studies on the association between physical activity and body fat distribution present inconsistent results.

End-to-end versus end-to-side motor and sensory neurorrhaphy in the repair of the acute muscle denervation.

Background: The aim of this study was to experimentally compare end-to-end and end-to-side neurorrhaphy in perineural window model after motor nerve lesion, evaluating which one was the most effective to preserve nerves. Also, differences in motor and sensorial nerve regeneration were tested to verify differences in nerve regeneration.

Methods: A total of 20 adult male Wistar rats were randomly assigned to 5 groups, and, in each one, a different treatment was performed: besides the control group, and end-to-end or end-to-side graft with motor or sensorial nerves was performed.

Intracranial intrasellar kissing carotid arteries: case report.

Intracranial "kissing" carotid arteries are a rare variant of the carotid arteries, where both internal carotid arteries deviate medially and touch each other near the midline within the sphenoid sinus or the sphenoid bone, including the sella. This anomaly is particularly important since it may cause or mimic pituitary disease and also may complicate transsphenoidal surgery. We report a rare case of intracranial intrasellar kissing carotid arteries in a 57-years-old woman that was submitted to a computed tomography angiography during investigation of a sudden headache, and to discuss the clinical relevance of this radiological finding.

Symptomatic thoracic spinal cord compression caused by postsurgical pseudomeningocele.

We report the first case of symptomatic thoracic spinal cord compression caused by postsurgical pseudomeningocele. A 49-year-old man sought treatment for progressive loss of strength in the lower extremities ten months after full neurological recovery for a thoracic (T11) intradural-extramedullary schwannoma. Magnetic resonance imaging revealed a postsurgical thoracic (T11-T12) pseudomeningocele.

Stereotactic computed tomography-guided brain biopsy: diagnostic yield based on a series of 170 patients.

Background: Stereotactic CT-guided biopsy is a valuable and safe procedure for diagnosing intracranial lesions. The objectives of this article are to analyze the diagnostic yield in a series of stereotactic CT-guided brain biopsies and to evaluate whether predictive factors may influence diagnostic yield.

Methods: The medical records of a series of patients who underwent stereotactic CT-guided brain biopsy from 1993 to 2005 in a neurosurgical center were reviewed.

Early surgical treatment of nonsyndromic craniosynostosis.

Background: Craniosynostosis, a premature fusion of cranial sutures, can happen as an isolated defect (nonsyndromic) or as part of a syndrome. It may lead to raised intracranial pressure and deformity of both the cranial and facial skeletons. Early surgery is usually the best treatment choice.
