ABSTRACT
Objective:To investigate the clinical efficacy and adverse reactions of linezolid in the treatment of gram-positive coccal infections after chemotherapy in older adult patients with leukemia.Methods:Ninety-two older adult patients with leukemia complicated by gram-positive coccal infections, who received treatment in Yiwu Central Hospital from January 2017 to December 2019, were included in this study. They were randomly assigned to receive routine anti-infection treatment (control group, n = 46) or linezolid treatment (observation group, n = 46). Clinical efficacy, the time required for body temperature restoring to normal, and medication time were compared between the two groups. Results:Total response rate was significantly higher in the observation group than in the control group [95.65% (44 /46) vs. 78.26% (36/46), χ2 = 6.13, P = 0.013]. The time required for body temperature restoring to normal and medication time in the observation group were (7.98 ± 1.04) days and (8.58 ± 1.31) days, respectively, which were significantly shorter than those in the control group [(8.85 ± 1.47) days, (9.46 ± 2.52) days, t = 3.27, 2.10, P = 0.001, 0.019). The incidence of adverse reactions was significantly lower in the observation group than in the control group [4.35% (2/46) vs. 19.57% (9/46), χ2 = 5.05, P < 0.05]. Conclusion:Linezolid is highly effective on gram-positive coccal infections after chemotherapy in older adult patients with leukemia. Linezolid treatment requires comparatively shorter time required for body temperature restoring to normal and shorter medication time and is safer than routine anti-infection treatment.
ABSTRACT
Objective:To summarise the clinical experience in replantation of the severed auricle distal to helix with microsurgical technique.Methods:From December 2018 to October 2021, a total of 5 patients with severed auricle injury were treated in the Department of Hand and Foot Surgery of The Affiliated Hospital of Qingdao University. They were 4 males and 1 female with 23-62 years old. After complete debridement of the auricular pinna, the retrograde replantation method was used. For arteries: a dorsal vein of the foot was used to bridge the posterior auricular artery. For veins: 2 patients had the veins directly anastomosed, 2 had the arteriovenous bridging to the posterior ear vein with dorsal foot veins, and the veins in 1 case were not anastomosed. Among the patients, 2 developed venous occlusions after severed auricle, and were treated with bloodletting through small incision at the skin margin. Two patients who received the arteriovenous of the severed auriclse achieved good blood supply. All the patients underwent treatments including anti-freezing, anti-spasm and anti-infection after the emergency surgery. The follow-ups were conducted regularly by telephone and by display photos via WeChat after surgery.Results:All 5 severed auricles were successfully replanted and survived. Postoperative follow-up ranged from 3 months to 2 years, with an average of 10 months. In the 2 cases with venous crisis, the auricles had mild atrophy. All auricles had no obvious pigmentation, and had the sensation recovery back to normal in 1 year after surgery.Conclusion:The pre-judgment of blood vessel quality and high-quality microsurgery skills are the necessary pre-conditions for auricle replantation. For replantation of severed auricle, it is the key to prevent vascular crisis by having the injured blood vessels thoroughly removed.
ABSTRACT
Objective:To investigate the clinical effect of free posterior tibial artery perforator flap in repair of forefoot soft tissue defect.Methods:From January 2017 to January 2021, a retrospective study was conducted on 13 patients with forefoot soft tissue defect, metatarsal head exposed, and forefoot transverse arch integrity, including 9 males and 4 females. The age was (40.0±13.0) years old. Cause of injury: 8 cases of traffic accident injury, 5 cases of heavy object smashing injury. Seven cases had forefoot skin defect and toe damage, and 6 cases had forefoot skin avulsion injury, open toe fracture with tendon, blood vessel and nerve injury. The wound area was 4.5 cm×3.0 cm-8.0 cm×6.0 cm. VSD treatment was performed in the first stage, and free posterior tibial artery perforator flap was used for the second stage. The flap area was 5.5 cm×4.0 cm-9.0 cm×7.0 cm. Outpatient reviews scheduled at 1, 2, 3, and 6 months after surgery, through outpatient clinic, telephone or WeChat. The flaps were evaluated according to appearance, texture, sensory recovery, and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot function scoring system.Results:All 13 flaps survived. The follow-up lasted for 6 to 24 months. The feet were in good shape, walking with weight beries, and the flaps had satisfactory appearance without wear and tear. Five cases were S 3, 6 were S 2, and 2 were S 1. According to AOFAS ankle-hindfoot function score, 4 had excellent scores, 7 were in good, and 2 in fair. Conclusion:The free posterior tibial artery perforator flap has relatively constant perforators, and the pedicle of the middle and upper perforators is longer, and the flap can build part of the sensation. Posterior artery perforator flap is a good flat for repairing the soft tissue defects of the metatarsal head of the forefoot.

ABSTRACT
@#Objective To introduce the concept of long length finger reconstruction and our corresponding three operative methods. Methods In a series of 10 finger defect cases with one of their long finger amputated at or proximal to proximal phalanx, long finger reconstruction were accomplished with one of the three methods. First method: For emergency patients whose proximal finger segment were demolished, the donor second toe was transplanted intercalatedly with microsurgical technique between the original proximal finger stump and the saved distal finger segment. Second method: Bilateral second toes were harvested and connected together to form a long transplant in order to reconstruct a normal length finger. Third method: From one foot, the donor second toe is harvested with its dorsal and plantar skin flap. From the other foot, the second toe is harvested with its metatarsophalangeal joint and skin flaps from neighbouring sides of great and third toes. The skin covering will be perfect. During transplantation of the proximal transplant, the MPJ should be fixed at 90°plantar rotation position for better flexion. Results Uneventful survival of reconstructed fingers were obtained in all ten cases. Postoperative functional evaluation of the patients with standard set by Chinese Society of Hand Surgery showed to be excellent in 1 case, good in 5 cases and fair in 4 cases. The overall excellent/good rate was 60%. Conclusion By application of these three reconstruction methods, the challenging problem of long length finger can be solved to reasonable extent.
