For many years, retrobulbar and peribulbar anesthesia were the standard for cataract surgery; however, many serious adverse effects have been reported (1, 2). With the introduction of modern phacoemulsification cataract surgery, topical anesthesia without retrobulbar or periocular injections has become a well-established, minimally invasive technique (3). The addition of intracameral lidocaine ...
Background: Androgenic hair loss (AGA) and alopecia areata (AA) are common conditions which sometimes are histologically difficult to differentiate. This study was conducted to detect differentiating features of these two disorders with IHC analysis of T-cell subsets in the inflammatory infiltrates of alopecia areata and androgenetic alopecia. Methods: This cr...
BACKGROUND This randomized double-blind study examined the use of a new anesthetic agent, levobupivacaine 0.5%, which is the S(-)-enantiomer of a racemic mixture of bupivacaine, for peribulbar anesthesia and compared it with racemic bupivacaine 0.5% alone or in combination with hyaluronidase 10 IU/mL. METHODS A total of 160 patients undergoing ophthalmic surgery were randomized into four grou...
We audited a total of 1233 patients scheduled for elective cataract extraction or trabeculectomy using peri-bulbar anaesthesia. A bolus of propofol provided sedation to cover insertion of the block. During an initial two-year period we collected data on the amount of propofol used to sedate 481 patients. Multiple linear regression analysis was then used to obtain an equation to link the dose us...
Alopecia areata is a hair loss disorder in humans, dogs and horses with a suspected autoimmune aetiology targeting anagen hair follicles. Alopecia areata is only sporadically reported in cows. Recently, we observed several cases of suspected alopecia areata in Eringer cows. The aim of this study was to confirm the presumptive diagnosis of alopecia areata and to define the clinical phenotype and...
