RESUMEN
Objective To explore the therapeutic effect of different doses of botulinum toxin A injections on bromhidrosis.Methods A total of 200 cases were divided into mild-to-moderate group (N=100) and severe group (N=100) based on the grade of bromhidrosis,and each group was further divided into two groups:low dose group (50 cases) were treated by botulinum toxin A injections (100 U) and high dose group (50 cases) were treated with 200 U for bilateral axillary.The total effective rate and recurrence rate in both groups were compared.Results In the mild to moderate group,after treatment for 3 months,the total effective rate of both groups had no statistical difference (P＞ 0.05),and the same with recurrence rate in 6 months follow-up (P＞0.05).In the severe group,after treatment for 3 months,the total effective rate of the high dose group (82％) was significantly higher than that of the low dose group (64％),with statistical significance (x2 =4.110,P＜0.05).After 6 months follow-up,recurrence rate in the high dose group (22％) was significantly lower than that of the low dose group (46％),with statistical significance (x2 =6.417,P ＜ 0.05).Conclusions A suitable dose of botulinum toxin A can be selected based on the severity of bromhidrosis,which is a individualized therapy for cost savings and might have potential benefits for patients with osmidrosis.
RESUMEN
Objective@#To investigate the early diagnosis method of pulmonary embolism in patients with skin and soft tissue defects after trauma.@*Methods@#From January 2011 to July 2014, 5 patients with skin and soft tissue defects and pulmonary embolism after trauma were admitted to Department of Plastic Surgery and Burns of the Affiliated Drum Tower Hospital of Nanjing University Medical School, including 4 males and 1 female, aged 26-68 years. The medical records of the 5 patients were retrospectively analyzed. Hierarchical screening of patients with suspected pulmonary embolism was performed after admission for 4-45 days. Computed tomography pulmonary angiography (CTPA) was performed immediately in 2 patients who had hemodynamic disorder and were able to tolerate CTPA, and pulmonary embolism was confirmed. Clinical risk assessment was conducted for the other 3 patients who had no obvious hemodynamic disorder and only had clinical manifestations of pulmonary embolism such as chest tightness and dyspnea. Among the 3 patients, two of them were assessed as high risk possibility by clinical risk assessment and diagnosed with pulmonary embolism by CTPA immediately. The other one patient′s clinical risk assessment was moderate risk possibility, but D-dimer was positive, and the patient was diagnosed with pulmonary embolism by CTPA immediately. Wound exudation of all patients was collected within 1 week after admission for microbial culture, and wound debridement and skin grafting were performed according to the wound condition. The color Doppler ultrasonography of blood vessel on lower extremity was performed to determine deep venous thrombosis of lower extremity after appearance of symptoms of pulmonary embolism. The patient was immediately given urokinase or recombinant tissue plasminogen activator by intravenous infusion for thrombolysis after definite diagnosis of pulmonary embolism. The activated partial thromboplastin time (APTT) was monitored after treatment, and standardized anticoagulation began when APTT was equal to or lower than 70 seconds. The treatment results of patients, D-dimer measurement value, bed time before definite diagnosis of pulmonary embolism, number of patients underwent wound debridement during hospitalization, definite diagnosis time of pulmonary embolism after wound debridement, and number of patients with deep venous thrombosis of lower extremity and wound infection were recorded.@*Results@#Wounds with skin and soft tissue defects of all patients were completely healed, all skin grafts survived well, pulmonary embolism recovered well after timely treatment, and the trunk and branches of involved pulmonary artery recovered blood supply. The course of disease ranged from 1 month to 3 months. The measurement value of D-dimer was 2.4-31.7 mg/L, and the measurement values of D-dimer of 4 patients were equal to or higher than 5.0 mg/L. The bed time before definite diagnosis of pulmonary embolism was 4-46 days, with an average of 23.2 days. Four patients underwent wound debridement during hospitalization. The definite diagnosis time of pulmonary embolism after the wound debridement was 14-40 days, with an average of 20.5 days. Four patients were diagnosed with deep venous thrombosis of lower extremity. All patients had wound infection, and the bacteria causing wound infection included Pseudomonas aeruginosa of 2 cases, Staphylococcus aureus of 2 cases, and Enterococcus faecalis of 1 case.@*Conclusions@#In the diagnosis process of pulmonary embolism in patients with skin and soft tissue defects after trauma, D-dimer positive, long-term bed rest, experiencing operation during hospitalization, and with deep vein thrombosis and wound infection can be regarded as the key points for diagnosis. When a patient has clinical symptoms of pulmonary embolism and the above conditions, the clinician should promptly perform hierarchical screening, select the corresponding examination to confirm pulmonary embolism, and immediately perform thrombolysis for the patient with pulmonary embolism according to the patient′s tolerance, thereby improving patient survival rate.
RESUMEN
Objective@#To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident.@*Methods@#On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test.@*Results@#The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients).@*Conclusions@#Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.

Objective To explore the aesthetic results of medial upper Iip repair for skin and soft tissue defects using local flap.Methods According to the location and the size of upper lip defect,the modified rhomboid flap of 60 ° above the defect was designed to repair the wound in philtrum;the O-L flap along philtral column to vermilion border was designed to cover the wound close to the peak and lateral to philtral column.Results Twenty-one postoperative patients that underwent pigmented nevus removal (12 female,9 male;ages 16-33 years) had defects in philtrum for 10 cases and close to the peak and philtral column for 11 cases.The diameter of the defect ranged from 0.5 cm to 1.0 cm.All flaps survived primarily without any complications and follow-up was for 1 to 18 months with excellent outcomes in all cases.All patients were satisfied with contour and functions.No pigmented nevus recurrence occurred.Conclusions The flap designed according to the aesthetic principle could be used to repair medial upper lip defect of medium-sized,which not only obtains functional reconstruction,but also satisfies aesthetic results,with aesthetic subunits saved and scar concealed.
RESUMEN
Objective To explore a new methodology with bilateral rhomboid dermal flaps for surgical treatment of inverted nipple. Methods 36 cases with 64 inverted nipples were involved in this study. Among these cases, 8 of them were evaluated as mild degree, while 19 moderate and 9 severe. In this procedure, the bilateral rhomboid incisions were designed. The rhomboid skin was deepithelialized and two dermal flaps were created. Then these two dermal flaps were filled crosswise through the tunnel beneath the nipple and fixed as supporting. After the operation, the continuous traction of the nipple lasted for one week, and sutured out 10 days later. Results None of these 36 cases appeared nipple blood circulation disorder after operation. Postoperative follow-up for 6 months-3 years showed that the appearance of the nipple was satisfactory. There were no recurrence and sensory disturbance. Conclusions The method introduced in this study is simple, the appearance of nipple is natural and no complication has been found. The incision is larvaceous while the scar is invisible. Meanwhile this method is also benefit for reserving the function of breast-feeding. It is proved to be an ideal method for correcting the inverted nipple.
