he mid-frontobasal approach can be carried out with the help of several tools, thanks to the technical improvements in the neurosurgical field. Cutting thick bone is one of the drawbacks of the power saw, this needs rongeuring of the bone or the use of manual spiral wire with handle.1 The use of the Gigli saw2 requires additional time compared with power-driven drills, however, this is amply co...

We tested the hypothesis that fibroblasts, which had been genetically engineered to produce fibroblast growth factor-2 (FGF-2), can protect nigrostriatal dopaminergic neurons. Three groups of rats received either a burr hole only (n=5) or implantation of fibroblasts, which had been genetically engineered to produce beta-galactosidase (beta-gal) (n=8) or FGF-2 (n=8), at two sites in the right st...

The Barron artificial anterior chamber (Katena, Denville, NJ) is an innovative development in corneal transplant and lamellar surgery. The chamber is a specialized device that allows a donor corneoscleral cap of tissue to be anatomically positioned ‘‘epithelial side up.’’ The chamber is used to mount the donor tissue and maintain adequate pressure while lamellar dissection or full thickness tre...

A fragment of parietal bone from an adult individual of unknown sex exhumed from the collective burial of Praia da Samarra (Sintra, Portugal), dated to the end of the Neolithic, presents signs of different types of trauma. These include thinning of the skull vault and incisions marks. Differential diagnoses for these alterations are discussed: for the first one, depressed skull factures is the ...

PURPOSE To describe the methods and results of a new technique of eyelash trephination for treatment of trichiasis and distichiasis. METHODS The medical records of all patients who underwent eyelash trephination by the authors to treat trichiasis or distichiasis were reviewed. Gender, diagnosis, number of eyelids treated, follow-up time, and surgical outcome were recorded. The technique invol...

OBJECTIVES To evaluate the surgical outcomes of endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stenting in patients with distal or common canalicular obstructions. METHODS The medical records of 29 patients (31 eyes) from January 2001 to December 2009 who underwent endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone tube inser...
