A Clinical Analysis of Friction Burns Caused by Electric Scooters

Purpose@#Electric scooters have recently entered into wide use in South Korea because of their eco-friendliness and convenience. Associated accidents resulting in friction burns are also increasing, due to a lack of recognition of the regulations regarding drivable roads and speed limits. We present the clinical characteristics of friction burns induced by electric scooters.M ethods: We retrospectively evaluated the clinical records of 48 patients who visited our institution after accidents involving electric scooters from January 2018 to February 2022. Demographic data, including age, sex, time of the accident, the type and location of the friction burn, and associated injuries, were reviewed. @*Results@#The age of the patients ranged from 15 to 51 years. The most common injuries were superficial partial-thickness dermal burns, while 14 cases involved deep partial-thickness dermal burns. Multifocal injuries were present in a single patient in most cases. The face was the most commonly affected region, followed by the knees. The average treatment period was 13.0 days, but the follow-up period was longer in patients with facial bone fractures or other comorbidities. @*Conclusion@#Friction burns from electric scooters are increasing, but their clinical presentation and related statistics have not been reported yet. Since most patients were not injured or had only mild epidermal burns in regions with enough clothing, appropriate safety equipment can prevent burns from electric scooters. However, once accidents occur, patients often present with multiple other injuries in the extremities, so proper injury evaluation and management should be emphasized for shorter hospitalization and optimal outcomes.

MRI-Induced Full Thickness Burn on the Ear Lobule due to Pulse Oximetry: A Case Report

Magnetic Resonance Image (MRI) has been used as a safe, conventional and harmless diagnostic tool. However, thermal injuries have frequently been reported during MRI scanning due to the heat generated by the reaction with the magnetic field. It is recommended that metal-containing monitoring devices such as pulse oximetry and ECG monitoring leads should be removed prior to the start of the MRI scan, but these monitoring devices are inevitably placed in children or patients in the intensive care unit who have low compliance with the scan. Since the interaction between the metal probe or wire loop of pulse oximetry and the magnetic field can result in high thermal conduction, full-thickness burn can occur over the entire body surface during the MRI examination. Several cases of thermal burns from pulse oximetry on the fingers have been reported. However, we present a case of a full-thickness burn arising left earlobe in a 2-month-old child caused by the high conduction heat from pulse oximetry metal probe.

Early Coverage with Advancement Flap in Laser Induced Dermal Injury on Neck: A Case Report

Burn injury is one of the most common complications associated with laser procedure. A 38-year-old woman underwent laser procedure for skin rejuvenation on her neck at a local aesthetic clinic. At that time, the cooling system installed in the laser machine was out of order without known origin. The patient complained of pain during the procedure, but it was neglected. It resulted in 3(rd)-degree burn involving the subcutaneous fatty layer on her neck. On the fifth day after injury, early debridement and advancement flap was done under local anesthesia. After 7 days postoperatively, total stitch out was done and a 6cm-length linear and transverse scar remained. When deep dermal injury occurs, it will take a long time to heal on its own. Early debridement and advancement flap will be helpful to prevent wide burn scar.

Delayed formation of sterile abscess after zygomaticomaxillary complex fracture treatment with bioabsorbable plates

We present a patient who showed a sterile abscess after facial bone fixation with bioabsorbable plates and screws. He had zygomaticomaxillary complex and periorbital fracture due to falling down. The displaced bones were treated by open reduction and internal fixation successfully using bioabsorbable plate system. However, at postoperative 11 months, abrupt painless swelling was noted on the previous operation sites, left lateral eyebrow and lower eyelid. By surgical exploration, pus-like discharge and degraded materials were observed and debrided. The pathologic analysis revealed foreign body reaction with sterile abscess. This complication followed by bioabsorbable device implantation on maxillofacial bone surgery has been rarely reported in which we call attention to the maxillofacial plastic surgeons.

Huge Abscess due to Mycobacterium Abscessus Infection after Breast Augmentation

Periprosthetic capsular contracture, implant rupture, and deflation are well-known delayed complications of augmentation mammaplasty. However, infection remains the most common cause of reoperation after breast implant surgery. We report the case of a nontuberculous mycobacterial infection with huge abscess formation after augmentation mammaplasty. A 29-year-old woman visited our clinic with enlarged breasts after undergoing breast augmentation at a local clinic 4 years ago. She had no pain and tenderness, except some hardness around the breast margin. Nine months after surgery, her breasts began to grow larger, but showed no other typical symptoms, which led the patient to neglect the enlargement. After exploring through an inframammary approach, a large amount of serous fluid leaked out on both sides and we identified a huge abscess in a pocket localized in the submuscular plane. During exploration, the infected implants, which contained a pus-like fluid with a foul odor, were completely drained. The specimen culture revealed growth of Mycobacterium abscessus, which is a rare cause of infections after breast augmentation. While the overall incidence of mycobacterial infections after breast augmentation is low, our case demonstrates that huge abscess and granuloma formation should be considered as a potential complication of breast surgery.
