Sparking the Debate: Facial Injury Patterns from Fireworks.

The objective of this article is to estimate the incidence, injury patterns, and demographics of patients presenting to emergency departments (EDs) for facial injury sustained from fireworks. This was an analysis of a nationwide database. The National Electronic Injury Surveillance System (NEISS) was evaluated for facial injuries from fireworks from 2013 to 2017. Relevant entries were examined for incidence, patient characteristics, location of injury, and type of injury. There were 509 NEISS entries, extrapolating to an estimated 19,816 ED visits for head and neck injuries due to fireworks from 2013 to 2017. The number of visits per year due to fireworks has been relatively stable over the past 5 years with an average of 3,963 cases per year. Greater than 90% of injuries occurred in July. Males comprised the majority of patients (67%), with the median age of 16 years. Most common sites of injury were the eyeballs (41%), followed by midface including eyelids, periorbita, and nose (31%), ears (12%), and only minor incidence of oral injuries (2%). After burns, contusions were the second most common injury from fireworks, followed by lacerations and foreign body injuries. The majority of firework injuries occurred in teenagers, reinforcing the importance of greater safety regulations and age limits for purchasing fireworks. Nearly half the incidents were eye injuries, necessitating greater public education in protective eyewear and mandating their use during festive holidays. Furthermore, injury patterns reported in this analysis may serve as a valuable adjunct for enhancing clinical history taking and physical examination to look for concurrent injuries.

The seed and the soil: optimizing stem cells and their environment for tissue regeneration.

The potential for stem cells to serve as cellular building blocks for reconstruction of complex defects has prompted significant enthusiasm in the field of regenerative medicine. Clinical application, however, is still limited, as implantation of cells into hostile wound environments may greatly hinder their tissue forming capacity. To circumvent this obstacle, novel approaches have been developed to manipulate both the stem cell itself and its surrounding environmental niche. By understanding this paradigm of seed and soil optimization, innovative strategies may thus be developed to harness the true promise of stem cells for tissue regeneration.

Community-acquired methicillin-resistant Staphylococcus aureus hand infections in the pediatric population.

PURPOSE: Recent studies have reported rates of methicillin-resistant Staphylococcus aureus (MRSA) hand infections in patients without risk factors ranging from 26% to 73%. The purpose of our study was to review a large series of pediatric hand infections to determine the rate of MRSA and identify potential risk factors. METHODS: A retrospective review was performed on patients younger than 15 who were seen for hand infections (2001-2010). Patients were categorized according to medical problems, need for operation, abscess location, and mechanism of injury. Potential MRSA risk factors were assessed using a multivariate-regression model. RESULTS: During the 10-year period, 415 patients were seen for hand infections. A total of 146 patients met the inclusion criteria: patients younger than 15 years of age who presented to the plastic surgery service requiring consultation for hand infections. The overall prevalence of MRSA-positive cultures was found to be 30%. The prevalence of MRSA was 29% in healthy patients and 0% in immunocompromised patients. The prevalence of MRSA increased in a linear fashion from patients without documentation of incision and drainage procedures to patients adequately treated with bedside incision and drainage to patients who required surgical drainage. There was a trend toward a higher prevalence of MRSA in deep space abscesses compared to other abscesses. Patients with a history of trauma and previous MRSA infections had a higher rate of MRSA than other patients. CONCLUSIONS: Traditionally, MRSA has been associated with hospitalization, intravenous drug use, recent antibiotic use, and compromised immunity. In our study, more severe, deep-space abscesses requiring surgical drainage and patients with a history of previous MRSA infections were found to have a higher prevalence of MRSA. The immunocompromised patients had no cases of MRSA and had higher incidences of less virulent bacterial infections. This suggests that acquisition of community-acquired MRSA skin and soft tissue infections in children and adolescents might not be associated with the traditional risk factors. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.
