From Admission to Discharge-A Total Friction Burn Review from a Single Institution.

While most friction burns are adequately managed in an outpatient setting, many may require hospital admission, operative excision, and extended care. To this day, there is a wide variance in friction burn management. Our goal is to review the etiology, management, and outcomes of such burns warranting hospitalization. We conducted a retrospective review of all friction burns admitted to a single, American Burn Association-verified burn center from January 1, 2016 to December 31, 2020. A total of 28 (34%) patients required surgery for their friction burns and 15 (18%) ultimately required a split-thickness skin graft. The mean number of operations was 2.4 (95% CI 1.6-3.1). Overall, the operative group was younger (29.9 vs 38.3 years, P = .026), more likely to have a concomitant traumatic brain injury (25% vs 7%, P = .027), and had a longer hospital length of stay (17.5 vs 3.9 days, P < .001). Both groups had a similar overall TBSA (8.5% vs 10.0%, P = .35), but the operative group had a larger surface area comprised of third-degree burns (3.05% vs 0.2%, P < .001). Overall, friction burns resulting in hospital admission are associated with high-energy traumatic mechanisms and concomitant injuries. Patients who need operative intervention for their burns typically require multiple procedures often culminating in a split-thickness skin graft. While non-operative management of friction burns with topical agents has been found to be successful, patients with higher injury severity scores should be monitored very closely as they may require surgical excision.

The Pearls and Pitfalls of a Migrating Bullet Embolus.

Venous bullet embolism is an exceedingly rare trauma diagnosis that presents diagnostic and therapeutic challenges. We present the case of a 32-year-old man who sustained multiple gunshot wounds with a venous bullet embolism to the right pulmonary artery. Imaging at first demonstrated a bullet lodged within the right lower lobe. The patient underwent multiple bronchoscopies and ultimately was found to have a bullet embolus in the right pulmonary artery. Repeat endovascular attempts failed at removal, and during a right thoracotomy, the bullet migrated to the left pulmonary artery. Coil embolization of the left lower lobe pulmonary artery was performed, and the patient was found to be asymptomatic at the 1-year follow-up. To our knowledge, this is the first case to demonstrate coil embolization of the pulmonary artery as a method of endovascular treatment for a venous bullet embolus. We present this case report to emphasize the difficulty in diagnosis, localization, and management of a migratory bullet within the pulmonary circulation.

Nationwide trends in the use of subtotal cholecystectomy for acute cholecystitis.

BACKGROUND: Subtotal cholecystectomy is a viable alternative approach to the proverbial "difficult" gallbladder. To date, only a few studies have observed the establishment of those bail-out procedures as an increasingly common surgical practice. The purpose of this study is to assess nationwide trends of subtotal cholecystectomy through evaluation of operative variables and patient- and institution-level characteristics in procedure preference. METHODS: Data were obtained from the National Inpatient Sample for the years between 2003 and 2014. Patients with acute cholecystitis were categorized based on the ninth revision International Classification of Disease Clinical Modification procedure codes for open total, laparoscopic total, open subtotal, or laparoscopic subtotal cholecystectomy. Any patient younger than 18 years of age or with a preoperative stay >1 week was excluded. Logistic regression analysis was performed to evaluate significant patient- and institution-level characteristics associated with the performance of subtotal cholecystectomy. RESULTS: A total of 290,855 patients were evaluated. During the study period, the rate of open and laparoscopic subtotal cholecystectomy sharply increased (0.10% of all cholecystectomy procedures to 0.52% and 0.12% to 0.28%, respectively). The conversion rate from laparoscopic to open total cholecystectomy decreased from 10.5% to 7.6%. Subtotal cholecystectomies were performed at significantly higher rates in men (odds ratio: 1.95, P < .001), Asian Americans (odds ratio: 2.21, P = .037), and patients with alcohol abuse (odds ratio: 2.23, P < .001). Teaching hospitals (odds ratio: 2.41, P < .001) and those in rural areas (odds ratio: 2.26, P < .001) were more likely to perform subtotal cholecystectomies. CONCLUSION: Growing trends in the use of subtotal cholecystectomy suggest evolving surgical practices for acute cholecystitis. Our data suggests that several patient- and hospital-level characteristics might play a deciding role in procedure preference.

A nationwide analysis of failed irrigation and debridement for pediatric septic arthritis of the hip.

Irrigation and debridement (I&D) is the gold standard for treatment of pediatric septic arthritis of the hip. If the index surgery fails, subsequent surgery may be required to eradicate the infection, resulting in substantial increases in morbidity, healthcare costs, and psychosocial burden. The purpose of this study was to identify the incidence of failed I&D for pediatric septic arthritis of the hip, defined by the need for at least one subsequent surgical intervention, and potential risk factors for failed initial I&D. The Kids' Inpatient Database was used to extract data for pediatric patients diagnosed with septic arthritis of the hip from 1997 to 2012. Factors such as patient demographics, preoperative comorbidities, inpatient variables, and hospitals variables were assessed for associations with successful versus failed I&Ds. During the period examined, 3341 (94.3%) children were successfully treated with a single I&D, whereas 203 (5.7%) children required at least one additional surgery during the same hospitalization. Univariate analysis found anemia, coagulopathy, and electrolyte disorders to be associated with repeat surgery. Patients who required multiple surgeries had significantly longer lengths of stay (11.3 vs. 6.9 days), higher likelihood of being discharged with home health (39 vs. 25%), and higher total overall inpatient costs ($58 400 vs. $31 900). On the basis of the results of this study, the nationwide incidence of patients requiring multiple I&Ds was 5.7%. Patient preoperative comorbidities such as coagulopathy, and hospital characteristics such as government ownership and teaching status were significantly associated with failed initial I&D for septic arthritis of the hip. We believe this data can be useful in guiding future research efforts and providing clearer anticipatory guidance to patients and guardians. Level of evidence: Level III: Retrospective comparative study.

Patient and Practice Trends in Total Ankle Replacement and Tibiotalar Arthrodesis in the United States From 2007 to 2013.

INTRODUCTION: Both total ankle replacement (TAR) and tibiotalar arthrodesis (TTA) are used in the surgical management of ankle arthritis. Over the past decade, TAR instrumentation, techniques, and implants have improved, making the procedure more reliable and reproducible, thus making TAR more common. METHODS: The Nationwide Inpatient Sample database from 2007 to 2013 was used to obtain data on patients elder than 50 years who underwent either TAR or TTA. Differences in temporal, demographic, and diagnosis trends between TAR and TTA were analyzed. RESULTS: Between 2007 and 2013, 15,060 patients underwent TAR and 35,096 underwent TTA. Patients undergoing TTA had significantly more comorbidities (2.17 versus 1.55; P < 0.001). The share of TAR performed increased significantly from 2007 (14%) to 2013 (45%) (P < 0.001). From 2007 to 2013, we found a 12-fold increase in the odds of having a TAR for patients with posttraumatic osteoarthritis (P < 0.001), a 4.9-fold increase for those with primary osteoarthritis, and a 3.1-fold increase for patients with rheumatoid arthritis (P < 0.001). CONCLUSIONS: Over the past decade, the frequency of TAR has increased, particularly in patients with posttraumatic arthritis and osteoarthritis. Surgeons still perform TAR in healthier patients compared with TTA; however, because surgeons become more experienced with the technique, patients are undergoing TAR at a markedly higher rate. LEVEL OF EVIDENCE: Level III: retrospective comparative study.

Toward integrated molecular diagnostic system (i MDx): principles and applications.

Integrated molecular diagnostic systems ( iMDx), which are automated, sensitive, specific, user-friendly, robust, rapid, easy-to-use, and portable, can revolutionize future medicine. This review will first focus on the components of sample extraction, preservation, and filtration necessary for all point-of-care devices to include for practical use. Subsequently, we will look for low-powered and precise methods for both sample amplification and signal transduction, going in-depth to the details behind their principles. The final field of total device integration and its application to the clinical field will also be addressed to discuss the practicality for future patient care. We envision that microfluidic systems hold the potential to breakthrough the number of problems brought into the field of medical diagnosis today.
