ABSTRACT.Purpose: To report our experience in endoscopic dacryocystorhinostomy in treating nasolacrimal duct obstruction over a 14-year period. Methods: Retrospective case series carried out over a 14-year period from 1999 to 2014. A total of 624 endoscopic dacryocystorhinostomy procedures were performed in 442 patients who were diagnosed with persistent epiphora. Participants: In total, 624 procedures in a total of 442 patients (<18 yo: 36 and >18 yo: 406) were included. Patients' records were assessed for demographics, intra-and postoperative complications, outcome and follow-up. Results: In total, 442 patients underwent an endoscopic dacryocystorhinostomy. There were 342 females (77.3%) and 100 males with a mean age of 50.2 years. All patients presented with epiphora: 33 congenital (7.5%), 357 acquired (80.7%) and 52 functional cases (11.8%). The adult dacryocystorhinostomy (n = 577) had an anatomical success of 90.1%. Children's group (<18 yo) n = 36 with a total of 47 procedures and an anatomical success of 91.5%. Functional cases (all adults -n = 52) showed a 91% benefit after operation. In 624 DCRs, we found a complication rate of 3.2%. Conclusion: Endoscopic dacryocystorhinostomy offers good success rates with a safety profile and efficacy equivalent to the traditional external approach is an effective treatment with good outcome results in adults and children with persistent or functional epiphora.

Background and Purpose-There is uncertainty whether bilateral near infrared spectroscopy (NIRS) can be used for monitoring of patients with acute stroke. Methods-The NIRS responsiveness to systemic and stroke-related changes was studied overnight by assessing the effects of brief peripheral arterial oxygenation and mean arterial pressure alterations in the affected versus nonaffected hemisphere in 9 patients with acute stroke. Results-Significantly more NIRS drops were registered in the affected compared with the nonaffected hemisphere (477 drops versus 184, PϽ0.001). In the affected hemispheres, nearly all peripheral arterial oxygenation drops (nϭ128; 96%) were detected by NIRS; in the nonaffected hemispheres only 23% (nϭ30; Pϭ0.17). Only a few mean arterial pressure drops were followed by a significant NIRS drop. This was however significantly different between both hemispheres (32% versus 13%, Pϭ0.01). Conclusions-This pilot study found good responsiveness of NIRS signal to systemic and stroke-related changes at the bedside but requires confirmation in a larger sample. (Stroke. 2012;43:1134-1136.)

Our study adds another 5 cases to the growing body of reports confirming the efficacy and safety - under controlled circumstances - of propranolol therapy in orbital IH management, in which we highlight the use of propranolol as both a final diagnostic tool and as an adequate treatment.

The IC injections and oral propranolol medication equally improved amblyopia in children with IH of the periorbital and cheek region; however, propranolol was associated with fewer complications and additional or supportive treatment was not indicated. We prefer oral propranolol medication over IC injections in cases in which IH threatens to hamper visual acuity.
