Ameloblastoma is an odontogenic tumor that usually occurs in the mandible. It is an aggressive but benign tumor of epithelial origin that is rarely metastatic. We report the case of a 53-year-old woman who had a massive ameloblastoma of the mandible. The tumor measured 15.2 x 11.4 x 12.0 cm. The patient had oral bleeding that required a transfusion. The workup included three-dimensional imaging, arteriography, and embolization to control bleeding. Surgical management entailed the resection of the entire left mandible and right symphysis, followed by reconstruction with a free fibular flap. To our knowledge, this is the largest reported ameloblastoma managed with three-dimensional imaging, radical resection, and free-flap reconstruction. This article also reviews aspects of the differential diagnosis, pathology, and management of jaw tumors. [ABSTRACT FROM AUTHOR]

Abstract: Objective: Display the cost savings of minimal sterile covers and preparatory time while still maintaining optimal outcomes for sinus procedures. In-office non-sterile endoscopic sinus procedures have not shown a difference in infections and complications. Institutions continue to employ more “traditional” sterile preparation with similar procedures in the operating room. Multiple studies have also shown no significant difference in postoperative course when preoperative antibiotics are administered for sinus procedures. Methods: Endoscopic sinus procedures were selected (58 patients) to analyze itemized sterile costs. Drapes, gloves, gowns, and antibiotics were then tallied and compared to the same items for cochlear implants (14 procedures). The “sterile-prep” time was also analyzed and compared between the two procedures. Cost difference was analyzed. Results: Comparing the supplies used for sinus procedures (56) and cochlear implants, our average sinus cost was $10.19, compared to $34.64, with a difference of $24.45. This equated to a savings of $1418.00 in sinus procedure supplies that year. The difference in draping and scrubbing time showed a difference of 20min between groups, equaling a value of $1760 difference/case. This calculated to a savings of $10,2080 for sinus operating room time. There was no difference in patient outcomes with this surgical preparatory approach. Conclusion: Our analysis showed a large cost savings over a fiscal year in operative time and supplies. This did not compromise any patient outcomes given the already non-sterile nature of endoscopic sinus surgery. This practice can be adopted to greatly enhance efficiency without sacrificing surgical results. [Copyright &y& Elsevier]

Abstract: Objective: To determine incidence and etiologies of craniofacial injuries in the pediatric population through comparison of injuries caused by all-terrain vehicles and golf cart trauma. Study design: Case series with chart review. Setting: Level 1 trauma center. Subjects and methods: Retrospective review of pediatric traumas at a tertiary academic medical center from 2003 to 2012 identified 196 patients whose injuries resulted from accidents involving either all-terrain vehicles or golf carts. Data was collected and variables such as age, gender, driver vs. passenger, location of accident, Glasgow coma scale, Injury severity scale, Abbreviated injury scale, and presence or absence of helmet use were examined. Results: 196 pediatric patients were identified: 68 patients had injuries resulting from golf cart accidents, and 128 patients from ATV accidents. 66.4% of ATV-related traumas were male, compared to 52.9% of golf cart-related traumas. Ages of injured patients were similar between the two modalities with average age of ATV traumas 10.8 (±4.0) years and golf cart traumas 10.0 (±4.6) years. Caucasians were most commonly involved in both ATV (79.7%) and golf cart traumas (85.3%). 58.6% of all ATV related trauma and 69.1% of all golf cart trauma resulted in craniofacial injuries. The most common craniofacial injury was a closed head injury with brief loss of consciousness, occurring in 46.1% of the ATV traumas and 54.4% of the golf cart traumas. Temporal bone fractures were the second most common type of craniofacial injury, occurring in 5.5% of ATV accidents and 7.4% of the golf cart traumas. Length of hospital stay and, cases requiring surgery and severity scores were similar between both populations. Intensive care admissions and injury severity scores approached but not reach statistical significance (0.096 and 0.083, respectively). The only statistically significant differences between the two modalities were helmet use (P =0.00018%) and days requiring ventilator assistance (P =0.025). Conclusions: ATVs and golf carts are often exempt from the safety features and regulations required of motor vehicles, and ATV and golf cart accidents represent a significant portion of pediatric traumas. This study found that ATV and golf cart accidents contribute significantly to craniofacial trauma requiring hospitalization, with resultant morbidity and mortality. Further investigation of these injuries and their prevention in the pediatric population is needed before efforts to promote effective safety regulations for such vehicles in the future can be addressed.

Objective Determine the effects of household dishwashing on Tracheostomy Tube safety. Introduction Tracheostomy tubes accumulate biofilms, which may limit their lifespan. Frequent cleaning of the tubes is a method for biofilm prevention. Cleaning practices vary widely. Some families prefer dishwashing of tubes, but its effects are currently unknown. We hypothesize that dishwashing has no significant effect on the physical properties of tracheostomy tubes and can be recommended as a safe way to clean tracheostomy tubes. Methods Twenty 4.0 Shiley™ pediatric tracheostomy tubes were randomly assigned into dishwashed (DW) and non-dishwashed (NDW) groups, 10/group. DW tubes were subjected to 12 wash cycles. Each tube's hardness along with the surface spectra were analyzed to assess for chemical composition changes. Three cannula samples from each group were also randomly assessed with scanning-electron microscopy and scored by blinded examiners to assess for changes in surface heterogeneity. Results Hardness testing revealed a statistically significant difference (p = 0.0009) between the NDW and the DW group indicating increased fragility in the dishwashed tubes. Spectral analysis revealed loss of plasticizers, indicating decreased flexibility. Blinded electron microscopy scoring revealed increased surface heterogeneity in the DW group (p = 0.00007). Conclusion A significant decrease in tube hardness and increased surface heterogeneity were found with dishwashing. The spectral analysis demonstrated increasing fragility. We believe these effects could potentially lead to decreased mechanical safety. With increased surface heterogeneity there is a greater potential for biofilm formation. At this time, dishwashing cannot be recommended as a tracheostomy tube cleaning method. [ABSTRACT FROM AUTHOR]
