Objective: To investigate the clinical effects of expanded frontal flap and flip scar flap in repairing partial nasal defect. Methods: A retrospective observational study was conducted. From January 2012 to January 2022, 26 patients with partial nasal defects who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 19 males and 7 females, aged 5 to 61 years. The surgery was performed in 4 stages. In the first stage, a rectangular skin and soft tissue expander (hereinafter referred to as expander) with suitable rated capacity was planted in frontal region and expanded by injecting water regularly. In the second stage, flip scar flap was grafted to reconstruct nasal inner lining, whose area was about 10% larger than the area of defect. The expanded frontal flap with pedicle was transferred to repair the nasal defect, whose pedicle was supraorbital vessel or supratrochlear vessel on the contralateral side of the defect, and the area of expanded flap was 20% larger than the nasal defect area after resection and flipping of scar flap. The donor site of expanded flap was sutured directly. After 3 weeks of flap transferring, the flap was delayed in the third stage. After 1 week of delaying operation, the pedicle of flap was cut off in the fourth stage. The number, rated capacity, injection volume, and expansion time of embedded expanders were recorded. The occurrences of complications including infection, hematoma, ulceration of expanded flap after the first stage operation, and blood supply disorder or necrosis of flap after operation in the second and fourth stages were observed. All the patients were followed up for 1 year at least, and the color of flap, scar of frontal donor site, symmetry of bilateral eyebrows, and the nasal appearance and ventilated function of external nasal tract were observed. Results: A total of 26 expanders were embedded in 26 patients. The rated capacity of expanders ranged from 100 to 300 mL. The injection volume was 1.0 to 1.5 times of the rated capacity of expanders. The expansion time ranged from 2.5 to 4.0 months, with an average time of 3 months. There were no complications occurred after each operation. The follow-up showed that the color of flap was similar to the normal nasal skin, the scar of frontal region was not obvious, the bilateral eyebrows were basically symmetrical, the nose had excellent appearance, ventilation function of external nasal tract was not affected, while some of the patients had downward rotation or unapparent tip-defining point of nose. Conclusions: Using the flip scar flap to reconstruct the nasal inner lining and pre-expanded frontal flap to reconstruct the nasal skin, without free cartilage transplantation to repair the partial nasal defects can achieve satisfied nasal appearance post operation, without abnormal external nasal ventilation function.

Objective: To summarize the best evidence of prevention strategies for pressure injury in adult hospitalized burn patients. Methods: A bibliometric approach was used. Systematic searches were carried out to retrieve the published evidence of prevention strategies for pressure injury in adult hospitalized burn patients in the official websites of relevant academic organizations such as International Society for Burn injury, American Burn Association, and Japanese Dermatology Association, National Pressure Injury Advisory Panel, European Pressure Injury Advisory Panel, Pan Pacific Pressure Injury Alliance International Guidelines Website, foreign language databases such as UpToDate, BMJ Best Practice, MedSci, Joanna Briggs Institute Evidence-Based Practice Database, Cochrane Library, Web of Science, Embase, and PubMed, and Chinese databases such as China Biology Medicine disc, China National Knowledge Infrastructure, Wanfang Database, and China Clinical Guidelines Library. The literature types include clinical decision-making, evidence summary, guidelines, systematic review, and expert consensus. The search time was till February 21^st, 2023. Two researchers independently screened the literature and evaluated the quality, and other researchers extracted and graded the evidence according to the topic. Results: A total of 10 papers were included, including 6 evidence summaries, 3 guidelines, and 1 expert consensus, all with high literature quality. After extracting evidence and classifying, 27 pieces of best evidences were summarized from three aspects, including prevention training and supervision, risk assessment, and prevention measures of pressure injury. Conclusions: A total of 27 pieces of best evidences of prevention strategies for pressure injury in adult hospitalized burn patients were summarized from 3 aspects. Medical workers can follow the best evidence and give personalized prevention strategies according to the specific condition of adult hospitalized burn patients to reduce the incidence of pressure injury.

Objective: To explore the curative effects of medial plantar free flap in reconstructing electric burn wound and scar contracture in the palm. Methods: A retrospective observational study was conducted. From January 2020 to January 2023, 6 patients with electric burn wounds or scar contracture in the palm who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 5 males and 1 female, aged 35 to 55 years. The wound area was 5.0 cm×3.0 cm-8.0 cm×7.0 cm after the debridement of electric burn wounds or resection of scar in the palm. The medial plantar free flap anastomosed with cutaneous nerve was used for wound reconstruction, with flap area of 5.5 cm×3.5 cm-8.5 cm×7.5 cm. The wound in the donor site was repaired with transplantation of abdominal full-thickness skin graft. After surgery, the survival of flaps and skin grafts were observed, the shape and texture of flap and the recovery of donor site of flap were observed, and the holding function of the affected hand was assessed. At the last follow-up, the two-point discrimination distance of flap was measured, the sensory recovery of flap was evaluated with the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association, and the function recovery of flap was evaluated by post-surgery flap function evaluation scale. Results: After surgery, 5 flaps survived well, while the distal part of 1 flap was partially necrotic, which was repaired by medium-thickness skin graft from lateral thigh after debridement. All the skin grafts at the donor sites survived well. During follow-up of 3 to 24 months, the flap was not bloated, the texture and color were good, the match with the surrounding tissue was high, with no obvious scar contracture occurred at the donor site. The affected hand had good holding function. At the last follow-up, the two-point discrimination distance of flap was 6-8 mm, the flap sensation recovery was as follows: 5 flaps recovered to grade S3⁺, 1 flap recovered to grade S3, and the functional evaluation of flaps was excellent in 5 cases and good in 1 case. The patients basically returned to normal life and work. Conclusions: The medial plantar free flap with cutaneous nerve anastomosis has many advantages, such as high matching degree of appearance, good sensory recovery, and holding function of the affected hand. It is an ideal choice for the reconstruction of the electric burn wound and scar contracture in the palm.

High-voltage electric burn is one of burns that can cause severe damages to tissue and organs. Clinically, progressive injury in high-voltage electric burns is a key pathological change that affects the level of amputation and the success rate of treatment. At present, the exact definition and mechanism of progressive injury in high-voltage electric burns have not been elucidated, and the clinical treatment is mainly symptomatic treatment. Relevant research data on the mechanism and treatment of progressive injury in high-voltage electric burns are lacking. This paper analyzes and summarizes the mechanism, diagnosis, treatment, and common outcome of progressive injury in high-voltage electric burns, and provides a reference for the mechanism research, clinical diagnosis and treatment of progressive injury in high-voltage electric burns.

In May 16^th, 2019, a male patient (aged 51 years) with a rare giant ulcer caused by skin diffuse large B-cell lymphoma in the axilla was admitted to Tongren Hospital of Wuhan University & Wuhan Third Hospital, and the ulcer wound was confirmed by biopsy and immunohistochemical analysis after extensive excision. Ultimately, a good prognosis was obtained by transplantation of flap and skin graft in combination with radiotherapy and chemotherapy.

Cognitive disorders after burns is an important problem that cannot be ignored in the diagnosis and treatment of burn patients. Its mechanism may be related to the activation of inflammatory response, destruction of the blood-brain barrier, hypothalamic-pituitary-adrenal axis imbalance, nerve cell changes, etc. Mechanism-specific prevention and treatment will be the best choice to reduce post-burn cognitive disorders in the future. This review introduces the research advances in epidemiology, risk factors, possible pathogenesis, diagnosis, treatment, and prevention of cognitive disorders in burn patients, in order to provide a reference for timely and accurate assessment, treatment, and prevention of cognitive disorders in burn patients.
