High-voltage electric burns is refractory with high rate of amputation (46%) in early stage and unfavorable functional recovery in later stage. Little breakthrough has so far been made in this respect. From Jan. 1985 to Jan. 1996, ninety-six cases with high-voltage burns were treated in our department. Seventy-one cases of various tissue flap grafting were applied to treat early electric burns, among which sixty-four cases were successful. The amputation rate was reduced to 30%. Postoperatively, a long-term rehabilitation training at home was carried out. Most of them achieved a good appearance of the wounded sites and limbs and satisfactory ability to work or self-care. It was suggested that early thorough debridement of necrosis tissue, careful reservation of living tissue, appropriate choice of tissue flap and postoperative rehabilitation training were of great importance to achieve a good prognosis.
Objective To study the preventive measure of the subambient temperature burn by analysing the pathogenesis feature. Methods The cl inical data were analysed from 351 cases of subambient temperature burn between February 2004 and February 2009, including age, sex, burn season, burn factors, burn position, burn area, burn degree, treatment way, and wound heal ing. Results Subambient temperature burn occurred in every age stage. The susceptible age stages included infant, children, and the elderly. Female patients were more than male patients. The common burn reasons werehot-water bottle burn, honey warm keeper burn, and heating device burn. The peak season was winter. Lower l imb was the most common site of the subambient temperature burn. The deep II degree to III degree were the most common level, and the burn area was always small, often 1% of total body surface area. Most of patients were treated with changing dressings at cl inic and few patients needed hospital ization. Though the surface of wound could heal finally, and the wound healed well with no obvious scar in patients who received operation. Conclusion Subambient temperature burn is the frequently encountered disease in winter. Use of the warming articles should be cautious, at the same time safety awareness should be strengthened so as to decrease the incidence rate of subambient temperature burn and the injury degree.
ObjectiveTo investigate the feasibility and effectiveness of repairing temporal skin and soft tissue defects and reconstructing sideburns with superficial temporal artery composite perforator flap.MethodsBetween January 2018 and January 2019, 12 patients with temporal tumors were treated. There were 5 males and 7 females with an average age of 51 years (range, 37-68 years). There were 8 cases of basal cell carcinoma and 4 cases of squamous cell carcinoma. The disease duration ranged from 3 months to 4 years (mean, 13 months). The area of residual wound after tumor resection was 3.8 cm×2.5 cm-5.2 cm×3.5 cm. The superficial temporal artery composite perforator flap was designed. The hairy superficial temporal artery frontal branch perforator flap was used to repair the hair growing area and reconstruct the sideburn; and the area of the flap was 2.5 cm×1.0 cm-4.2 cm×3.0 cm. And the superficial temporal artery descending branch perforator flap without hair was used to repair the hair-free area; and the area of the flap was 2.5 cm×1.5 cm-7.5 cm×4.0 cm. The donor sites were sutured directly.ResultsAll flaps survived, and the incisions at the donor and recipient sites healed by first intention. Eleven patients were followed up 6-12 months (mean, 9 months). The incisions were not obvious. The flaps were flat and the color of the flaps were not significantly different from the surrounding skin. The reconstructed sideburns were consistent with the healthy side and the facial appearance was satisfactory. No local tumor recurred during follow-up.ConclusionFor the temporal skin and soft tissue defects involving the sideburn, the superficial temporal artery composite perforator flap can be used to repair subunits with different aesthetic characteristics in sections and has the advantages of operating simply, obtaining satisfied facial appearance, and little effect on the donor site.
【Abstract】 Objective To explore the effect of early scrotal dermatoplasty on spermatogenic functional rehabilitation of testis in juvenile pigs with third degree burn wound of the scrotum. Methods Thirty healthy male Guizhou miniature pigs (weighing 10-15 kg, 2-month-old) were divided into 3 groups: control group (group A, n=10), natural healing group (group B, n=10), and dermatoplasty group (group C, n=10). In group A, the pig was not given any treatment; after third degree burn model of the scrotum was prepared, wounds were not treated in group B and the burn skin was excised and whole hypogastric pachydermia was used for dermatoplasty in group C. At 3 months and 1 year after model preparation, bilateral testis were collected from 5 pigs, respectively. HE staining was performed to observe the effects of different repair method on the morphology of spermatogenic cells and immunohistochemical staining was used to detect Survivin protein expression. Results All pigs survived to the end of the experiment and the wound healed successfully. Histological observation showed that spermatogenic cells had normal shape at all stages and mature sperms were seen in lumens in group A; the thickness of seminiferous epithelium was thinner, having one layer or two layers of spermatogenic cells in group B; the spermatogenic cells in group C were slightly more than that in group B with some spermatids; and in groups B and C, the spermatogenic cells at 1 year were more than that at 3 months. Immunohistochemistry staining showed that the Survivin protein expression in groups B and C was less than in group A, and group B was less than group C, showing significant differences at 3 months and 1 year (P lt; 0.05), but no significant difference between 3 months and 1 year in the same group (P gt; 0.05). Conclusion Dermatoplasty has inhibitory effect on spermatogenic functional rehabilitation of testis. Dermatoplasty can decrease spermatogenic cells and reduce Survivin protein expression, but some spermatids still survive in seminiferous tubule.
Abstract Postburn deformities, including hypertrophic scars, scar contracture and defect or deformity of tissue or organ, are the commonest disorders in plastic surgery. It is also difficult to deal with. If the diformity involved multiple organs, oftentimes the teatmentis very difficult because the material for repair is limited and the donorsite usually could not provide adequate amount of skin for repair. Since 1978,2496 cases of various postburn deformities were admitted. In this article, theoptimal time to operate was discussed. The use of flap transfer and soft tissueexpander was described. Prolonged traction in the treatment of severe contracture of large joint was also described.
OBJECTIVE: To evaluate the therapeutic effect of amniotic membrane transplantation(AMT) for ocular burn. METHODS: Twenty patients with ocular burn(28 eyes) were treated with amniotic membrane transplantation. Of them, there were 6 cases of severe alkali burn(10 eyes), 8 cases of severe acid burn(10 eyes), and 6 cases of thermal burn(8 eyes). RESULTS: In 28 eyes, ocular inflammation was controlled after 3-7 days of surgery; no continued dissolution, perforation and iris atrophy were found. There were corneal transparency in 16 eyes, keratoleukoma in 4 eyes, and total corneal opacity in 8 eyes. All eyeballs were saved and had stable ocular surface. There was no allograft immune rejection and secondary infection. CONCLUSION: Amnitic membrane transplantation can relieve the inflammatory reaction, reduce the growth of blood vessel and restrain the proliferation of fibrous tissue. It is an effect surgical method for ocular burn in reconstruction of ocular surface and salvage of eyeball.
Objective To investigate the effectiveness of autogenous platelet-rich plasma (PRP) gel with acellular xenogeneic dermal matrix in the treatment of deep II degree burns. Methods From January 2007 to December 2009, 30 cases of deep II degree burns were treated. There were 19 males and 11 females with an average age of 42.5 years (range, 32-57 years).The burn area was 10% to 48% of total body surface area. The time from burn to hospitalization was 30 minutes to 8 hours. All patients were treated with tangential excision surgery, one side of the wounds were covered with autogenous PRP gel and acellular xenogeneic dermal matrix (PRP group), the other side of the wounds were covered with acellular xenogeneic dermal matrix only (control group). The heal ing rate, heal ing time, infection condition, and scar formation were observed. Results At 7 days after operation, the infection rate in PRP group (6.7%, 2/30) was significantly lower than that in control group (16.7%, 5/30, P lt; 0.05). The healing times were (18 ± 4) days and (22 ± 4) days respectively in PRP group and control group, showing significant difference (P lt; 0.05). The healing rates at 14 days and 21 days were 75% ± 7% and 88% ± 5% in PRP group, were 62% ± 15% and 73% ± 7% in control group, showing significant difference (P lt; 0.05). RPR group was superior to control group in elasticity, color, appearance, softness, scar formation, and heal ing qual ity. Conclusion Autogenous PRP gel with acellular xenogeneic dermal matrix can accelerate the wound healing of deep II degree burns as well as alleviate the scar proliferation.
Objective To introduce the technique of esophageal intraluminal stenting and assess its effect on the prevention of development of stenosis in patients with esophageal burns. Methods Thirty-three patients were admitted less than 3 weeks after ingestion of caustic agents. The second-or third-degree injuries were confirmed by esophogoscopy in all cases, but one with esophageal perforation at admission. Esophageal stenting was performed in all patients and these stents were kept in place for 4 to 6 months. Results There was no death in the series. All patients had a normal intake of food after removal of the stents, and stricture was not found on barium swallow test. Follow-up from 1 to 60 months five cases developed esophageal stenosis from 2 to 3 months after extracting the stents. One of them responded to esophageal bougienage, the remaining 4 patients required esophageal reconstruction and took a normal diet postoperatively. The other 28 patients have a normal diet after the stent removal. Conclusion The esophageal intraluminal stenting is able to prevent the formation of stricture in the aftermath of esophageal burns and its effect will be enhanced plus administering isoniazid.
ObjectiveTo study whether emotional management can alleviate the occupational burnout of the health care providers.
MethodsFrom May 1st 2015 to February 29th 2016, we sampled the medical workers of a class-3 grade-A hospital randomly, and performed the emotional management through self-emotion management and professionals-conducted emotion-management. The discrepancies before and after intervention were studied using Maslach Burnout Inventory General Survey (MBI-GS).
ResultsIn total, 100 medical workers were enrolled in our study, of which there were 27 males and 73 females. There were 11 doctors and 89 nurses. The average age was (34.5±5.6) years. According to the MBI-GS survey, there were 69 medical workers suffering from occupational burnout. There were significant statistical differences before and after intervention in the MBI-GS scores in four aspects including emotion exhaustion, work status, sense of achievement and the total scores (P＜0.05).
ConclusionThe medical workers can alleviate the occupational burnout under the self-management or professionals-conducted management of emotion.
Objective
To explore the feasibility and effectiveness of sideburn reconstruction using the expanded island scalp flap based on the parietal branch of the superficial temporal vessel.
Methods
Between February 2012 and April 2015, 7 patients underwent sideburn reconstruction. There were 3 males and 4 females with an average age of 15 years (range, 4-44 years). The etiologies included burn injury in 3 cases, trauma in 1 case, radiation therapy in 1 case, and congenital melanocytic nevus in 2 cases. The size of the sideburn defects ranged from 5.0 cm×3.5 cm to 16.0 cm×10.0 cm. At the first-stage, according to the sideburn defect, a tissue expander of the appropriate size was inserted beneath the superficial temporal fascia which containing the parietal branch of the superficial temporal vessel. Postoperatively, regular saline injection was commenced. After 3-6 months of the first-stage surgery, the expander was adequately inflated. While the second-stage surgery was performed, the lesion was excised and the tissue expander removed. The expanded island scalp flap based on the parietal branch of the superficial temporal vessel was harvested and advanced towards the defect of the sideburn according to the contralateral normal one, and the size of flap ranged from 8 cm×3 cm to 17 cm×11 cm. The donor site was closed primarily.
Results
All flaps survived and the wound and donor sites were healed primarily without any complication. All patients were followed up 1-36 months (mean, 9.8 months). The profile, hair density, and hair direction of the new sideburn were similar to the contralateral sideburn. In 1 patient, the reconstructed sideburn was a little larger than the contralateral normal one. After laser hair removal, the patient was satisfied with the appearance.
Conclusion
The expanded island scalp flap based on the parietal branch of the superficial temporal vessel provides an effective option for the sideburn reconstruction, which presents with the similar appearance to the contralateral one.
