Long-term outcome of trans-scleral diode laser cyclophotocoagulation in refractory glaucoma

BACKGROUND: Long-term outcome and complications of diode laser cyclophotocoagulation (DCPC) may be important, since eyes, once treated with DCPC, are less likely to be subjected to other types of interventions in the further follow-up. METHODS: Retrospective review of 131 eyes of 127 patients treated from 2000 through 2004. Success was defined as intraocular pressure (IOP) at last visit 6-21 mm Hg; hypotony: IOP traumatic glaucoma, and patients were significantly younger. All eyes had refractory glaucomas on maximal medication, neovascular glaucoma (NVG) representing the largest subgroup (61%). IOP decreased from 36.9 (10.7) mm Hg pretreatment to 15.3 (10.4) mm Hg at the end of FU. Success was noted in 69.5% (91 eyes), failure (non-response) in 13%. Hypotony occurred in 17.6% eyes, of which 74% had NVG. Hypotony developed after mean 19.3 (11.0) months, range 6 to 36; with 96% of these eyes having received only 1 or 2 treatments; delivered energy did not differ from that in the successful eyes. CONCLUSIONS: DCPC is an efficient treatment for refractory glaucoma. Hypotony, the most common complication, may develop as late as 36 months post-treatment. Diagnostic category and age seem to influence the outcome stronger than laser protocol and delivered energy.

Pediatric craniofacial trauma

PURPOSE: Maxillofacial and skull fractures occur with concomitant injuries in pediatric trauma patients. The aim of this study was to determine the causes and distributions of maxillofacial and skull fractures as well as concomitant injuries of pediatric patients in Switzerland. Results were compared with worldwide studies. MATERIALS AND METHODS: A retrospective review was conducted of 291 pediatric patients with maxillofacial and skull fractures presenting to a level-I trauma center over a 3-year span. Data concerning the mechanism of the accident and the topographic location of the injuries were analyzed. RESULTS: The most common causes were falls (64%), followed by traffic (22%) and sports-related accidents (9%). Fifty-four percent of the fractures occurred in the skull vault and 37% in the upper and middle facial third. One third of the patients (n = 95) suffered concomitant injuries, mostly cerebral concussions (n = 94). CONCLUSIONS: The spectrum of craniofacial injuries is related to the specific developmental stage of the craniofacial skeleton. It is probable that national prevention programs will have a positive effect on reducing the incidence of falls. Standardization of studies is needed for international comparison.

Total-body digital X-ray in trauma. An experience report on the first operational full body scanner in Europe and its possible role in ATLS

When patients enter our emergency room with suspected multiple injuries, Statscan provides a full body anterior and lateral image for initial diagnosis, and then zooms in on specific smaller areas for a more detailed evaluation. In order to examine the possible role of Statscan in the management of multiply injured patients we implemented a modified ATLS((R)) algorithm, where X-ray of C-spine, chest and pelvis have been replaced by single-total a.p./lat. body radiograph. Between 15 October 2006 and 1 February 2007 143 trauma patients (mean ISS 15+/-14 (3-75)) were included. We compared the time in resuscitation room to 650 patients (mean ISS 14+/-14 (3-75)) which were treated between 1 January 2002 and 1 January 2004 according to conventional ATLS protocol. The total-body scanning time was 3.5 min (3-6 min) compared to 25.7 (8-48 min) for conventional X-rays, The total ER time was unchanged 28.7 min (13-58 min) compared to 29.1 min (15-65 min) using conventional plain radiography. In 116/143 patients additional CT scans were necessary. In 98/116 full body trauma CT scans were performed. In 18/116 patients selective CT scans were ordered based on Statscan findings. In 43/143 additional conventional X-rays had to be performed, mainly due to inadequate a.p. views of fractured bones. All radiographs were transmitted over the hospital network (Picture Archiving and Communication System, PACS) for immediate simultaneous viewing at different places. The rapid availability of images for interpretation because of their digital nature and the reduced need for repeat exposures because of faulty radiography are also felt to be strengths.
