From Jan. 1991 to Jan. 1994, 11 cases ofdifferent hip lesions with flexon contracture deformity were treated by combination of SmithPeterson and WatsonJones incisions in replacement of hip joint. All of them were followed-up for 1 to 3 years (an average of 1.9 years). According to pain, joint function, the excellent and good results were rated at 90.9%. This showed that from using the combined incisions, the hip joint was very well exposed, and release of hip flexion contracture could be acomplished in the same time. Bleeding fromoperation was reduced and the procedure was simple.
Objective To discuss the reconstruction of severe neck contracture by transplanting combined scapular/parascapular bilobar flaps, and the probability to reestablish three-dimensional movement of the neck. Methods From January 2003 to November 2004, 9 cases of sustained severeneck contractures were treated (aged 9-32 years). The combined scapular/parascapular bilobar flaps, pedicled on the circumflex scapular vascular bundle, were microsurgically used to cover the soft tissue defect after excision of hypertrophic scar and release of contracture. The maximum size of the combined bilobar flap was 20 cm×8 cm to 20 cm×11 cm，while the minimum one was 15 cm×4 cm to 15 cm×6 cm. Results The combined scapular/parascapular flapswere successfully used to treat 9 cases of severe neck contracture. All patients were satisfied with the final functional and aesthetic results. There was no recurrence during 3-9 months follow-up for 8 patients. The cervicomental angle was 90-105°.Conclusion The combined bilobar scapular/parscapular flap, providing a large area of tissue for coverage in three dimensions with a reliable blood supply by only one pedicle anastomosis during operation, is agood option for reconstruction of the severe neck contracture.
Objective To investigate the application of free flaps in combinedtransplantation and its clinical outcome. Methods From January 1991 to December 2003, 56 cases of combined transplantation involving cutaneous or myocutaneous flaps were performed to repair extremely large soft tissue defects, large-sized skin and segmental bone defects and to simultaneously reconstruct the missing thumb andrepair the associated skin defects in the first web space.Of the 56 patients, 37 were males, 19 were females. Their ages ranged from 5 to 41, 27.6 in average.The transplants included latissimus dorsi myocutaneous flap, scapular flap, lateral femoral flap, big toe skin-nail flap, and fibula. To establish blood circulation in the transplants, the common vascular pedicle was anastomosed directly to the vessels in the recipient site in 35 cases but to the selected vessels in the healthy limb in 21through a cross-bridge procedure. Results With failure in 2 cases of combined transplantation of latissimus dorsi myocutaneous flap and vascularized fibula, all the transplants survived well. In the 32 cases of long bone defects with successful repair, the transplanted fibulas united with host bones 14.5 weeks after operation on the average. A mean follow-up of 28 (10-128) months revealed thatfunction in all cases was recovered, while one patient, who underwent a successful combined transplantation of latissimus dorsi myocutaneous flap and vascularized fibula, required amputation of the involved leg 3 years after repair because of the repeated ulcers in the toes. Conclusion The application of free flaps incombined transplantation can lead to an effective repair of complicated tissue defects of the limb and to a successful reconstruction of the associated missing thumb.
Objective To evaluate on immunogenicity and safety of measles-mumps-rubella-varicella vaccine. Methods The PubMed, BIOSIS Previews, CDSR, The Cochrane Library, CBM, CNKI and VIP were searched between Jan. 1990 and April 2010. Studies were included in the review if they were randomized controlled trials (RCTs) about measles (M) – mumps (M) – rubella (R) and varicella (V) vaccine. Trial screening, data exaction and quality assessment of the included trials were conducted by the method recommended by Cochrane Collaboration. Statistical analyses were conducted by using RevMan 4.2.10 software. Results Five RCTs were included. Among those there were 2 trials of B degree and 3 trials of C degree. Meta-analyses showed that to different inoculation methods, (MMRV or MMR+V) the rate of pain was not significantly different with RR 0.94 and 95%CI 0.83 to 1.05 (P=0.28). The rate of redness was not significantly different with RR 1.08 and 95%CI 0.90 to 1.29 (P=0.40). The rate of hardening was not significantly different with RR 1.16 and 95%CI 0.95 to 1.43 (P=0.14). The rate of fever was significantly different with RR 1.20 and 95%CI 1.12 to 1.29 (Plt;0.000 01). The rate of skin rash was not significantly different with RR 1.18 and 95%CI 1.00 to 1.41 (P=0.05). The serum measles antibody positive rate was not significantly different with RR 1.00 and 95%CI 0.99 to 1.01 (P=0.68). The serum mumps antibody positive rate was not significantly different with RR 0.99 and 95%CI 0.50 to 1.01 (P=0.11). The serum rubella antibody positive rate was not significantly different with RR 1.00 and 95%CI 0.99 to 1.01 (P=0.68). The se-rum varicella antibody positive rate was not significantly different with RR 1.00 and 95%CI 0.99 to 1.01 (P=0.58). Conclusion Compared with MMR+V vaccine, the MMRV vaccine has the same immune effect. In respect of immune safety, in addition to higher rate of fever after vaccination, other local or systemic reaction is good. For the role of reducing vaccination times and good performance on immune effect and safety, the MMRV vaccine can be regarded as candidate vaccine for children. The fever caused by the new component should be strengthened in the following study. Limited to the quality and account for the current original documents, citing evidence of this systematic review would be cautious. Future studies would expand the sample size, fulfill the test design, increase indicators to improve the quality of research and demonstration intensity.
Objective To discuss the operative method and experience, through analyzing the medium-term and long-term effect of combined therapy for cutaneous squamous cancer of head and face. Methods From January 1998to December 2002, 37 patients with head or neck cutaneous squamous cancer received combined therapy of operation and radiation. The determination of resect area was based on the stage of the tumor, and according to the resect area and the freedom of peripheral tissue, 3 different operation procedures were adopted respectively. The follow-up was ended in June 2004. Results The follow-up was 5 to 69 months. The median follow-up interval was 38 months. Four patients (10.8%) relapsed during the follow-up, and 2 of them (5.4%) relapsed within 3 years after operation. two patients (5.4%) died from the primary affection, 4 patients (10.8%) died from other causes. According to Kaplan-Meier Method, the 3-year survival rate was 97.14% and the standard error was 0.0358, and 5-year survival rate was 92.28% and the standard error was 0.1047. Conclusion The recurrence rate of cutaneous squamous cancer of head and face witha better prognosis is lower than the ones from other origins. And the survival rate may be improved from proper operative method.
Objective To summarize the clinical experience in the treatment of refractory decubitus ulcers.Methods From May 1998to March 2005, 22 patients with decubitus ulcers(29 decubitus ulcers) were admitted, whose age was 3692 years. The lesion size was 4 cm×2 cm to 18 cm×15 cm. The locations of decubitus ulcers were the sacrococcygeal region(18 cases), the tuber ischiadicum region (6 cases) and the trochanter major region(5 cases).Enteral nutrientwas given orally and the wound was treated with Wuhuangyihao 8-15 days. Three diabetic patients were injected with insulin. According to patient’s age, ulcer position, ulcer extent and ulcer degree, the flap type was determined. Three wounds were repaired by local flaps, the flap size was 6 cm×4 cm-12 cm×10 cm; 10 by fasciocutaneous flaps, 10 cm×7 cm-20 cm×17 cm; 9 by gluteus maximusmyocutaneous flaps, 13 cm×11 cm-17 cm×14 cm; and 6 by longhead of biceps femoris flaps,11 cm×6 cm-14 cm×7 cm. One was sutured directly. After operation, the patients were placed on airflow suspended bed 7-14 days.Results General nutritional status was improved, hemoglobin was greaterthan 100 g/L, albumen was greater than 30 g/L. Necrosis tissue was removed, granulation tissue turned into fresh, secretion reduced and no redness and swelling occurred in wound. All flaps survived and the wounds healed by first intention. After a followup of 6 months to 5 years, no patient had a recurrence, the color and texture of the flaps were good, the appearance was satisfactory.Conclusion Applying the technique of combined treatment can accelerate the healing of refractory decubitus ulcers and improves the success of operation.
Objective To observe the cl inical results of treatment of Schatzker V/VI tibial plateau fracture involved posteromedial condyle through combined posteromedial and anterolateral approach and fixed with two or three plates. Methods From April 2005 to April 2008, 18 cases of tibial plateau fracture involved posteromedial condyle were treated, including 14 males and 4 females with an average age of 38.5 years old (range, 18-62 years old). According to Schatzker classification, there were 12 cases of type V and 6 cases of type VI. The posteromedial condyle were involved in 13 cases and bilateral posterior condyle in 5 cases. All patients were given posteromedial fragment and medial condyle fracture reduction through posteromedial approach firstly, and then lateral condyle fracture reduction through anterolateral approach, and injury of meniscuses and cruciate l igaments were treated at the same time. Three plates (lateral, medial, posterior) were used in 10 cases and two plates (lateral, posteromedial) in 8 cases. Results All wounds achieved heal ing by first intention without compl ications such as infection, flap necrosis, osteofascial compartment syndrome, chronic osteomyel itis, nonunion. All patients were followed up for 12 to 48 months with an average of 24.4 months. The mean flexion of the knee was 118.4° (range, 100-130°) 1 year after operation. According to Iowa evaluation system, 12 patients got excellent results, 4 good, and 2 fair; the excellent and good rate was 88.9%. Conclusion Combined posteromedial and anterolateral approach and fixed with two or three plates is effective in treatment of the Schatzker V/VI tibial plateau fracture involved posteromedial condyle. Anatomical reduction and rigid internal fixation of the posteromedial fragment are critical to successful operation.
ObjectiveTo observe the effects and security of dexmedetomidine in combined spinal epidural anesthesia (CSEA) for laparoscopic total extraperitoneal hernia repair (TEP). MethodsFrom January 2010 to January 2013, we selected 90 patients who were going to receive TEP surgery as our study subjects. The patients were divided into three groups:M1, M2 and M3 with 30 patients in each. The patients had left lateral position, and anesthesia was done between 3-4 lumbar epidural line. Injection of 0.5% bupivacaine 2 mL was carried out, and epidural catheter was 3-5 cm. Anesthesia plane was adjusted from the chest 4 or 6 vertebra to the sacral vertebra. The three groups of patients were treated with micro pump using dexmedetomidine given at a pre-charge of 0.5 μg/kg, and then group M1 was maintained by 0.3 μg/(kg·h), M2 by 0.5 μg/(kg·h), and M3 by 0.7 μg/(kg·h). The changes of mean arterial pressure (MAP), heart rate, respiration and pulse oximetry (SpO2) were observed at each time point, and bispectral index (BIS) monitor and Ramsay sedation score test were also conducted. ResultsThe changes of MAP, heart rate and respiration in group M1 were not obvious; the Ramsay score for group M1 was 2 to 3, and BIS value after pre-charge was 65-84. For group M2, MAP, heart rate and respiration had a slight decline; Ramsay score was 3-5 points, and BIS value was 60-79. In group M3, patients had a milder decline in their MAP and respiration; the heart rate declined obviously after receiving dexmedetomidine and one patient with severe decline of the heart rate alleviated after active treatment; Ramsay score was 5 to 6 points, and BIS value was between 55 and 75. There was little change in SpO2 in all the three groups, and the difference was not statistically significant (P>0.05). ConclusionContinuous injection of dexmedetomidine at 0.3-0.5 μg/(kg·h) in CSEA is an alternative way for anesthesia, which can effectively promote sedation and reduce pain and discomfort.
Objective To investigate the effect of combined types in treating cases with 2 to 5 tissues transplantation. Methods 305 cases treated from December 1989 to December 2002 were analyzed and summarized. 214 cases were constructed with 2 combined tissues transplantation, the combined types were:toe combined flap,the second toe at both sides transplanted,2 flaps combined transferred; 75 cases were constructed with 3 combined tissues transplantation,the combined types were:the second toe at both sides combined flap,2 flaps combined toe,3 flaps combined transferred;11 cases were constructed with 4 combined tissues transplantation, the combined typeswere:2 flaps combined 2 toes,1 toes combined 3 flaps,4 flaps combined transferred; 5 cases were constructed with 5 combined tissues transplantation, the combined type was:the wrap flap and the second toe with 1 vascular pedicle and another second toe combined bilateral femoris anterior flaps were transferred.The principles of repair were:the thumb was reconstructed first,the wrap round flap was used for the thumb’s skin,the second toe transplantation was used for the thumb defect.The opposite toe was transferred to finger to reconstruct the pinch function.1 or 2 flaps were selected for repair according to the area of damage. The anterolateral thigh flaps were used for the large areas and the lateral arm flaps were usedfor the small areas in selecting the donor area. Results Of the 722 tissues in 305 cases, 14 of them were necrosis, in which the toe were 6 and the flap were 8,and other transferred tissues all survived, the survival rate of tissue transplantation was 98.1%.251 cases were followed up for 1 year to7 years(2.6 years in average).All the patients could care themselves in daily life. The pinch and oppositionfunctions of the constructed thumbs and fingers were recovered,the two-point discrimination was 6 to 14 mm,but 2 cases recovered adduction function only because the thumb was 6 degree defect without the thenar muscle and did not fix the reconstructed thumb in opposite side in operation.All transplanted flaps recovered protecting sensory with S2,56 flaps required plastical operation because of their swelling appearance.The donor areas gained primary stage heal in 285 cases,20 cases gained secondary stage heal, in which part grafted skin necrosis in donor of wrap round flap were 12 cases,the distal of donor big toe necrosis were 2 cases and grafted skin necrosis in donorofanterolateral thigh flap were 8 cases and skin grafted were sucessful. Conclusion Different combined types can be used according to the traumatic situation. Surgical operation and early rehabilitation is conducive to the final function.Combined tissue transplantation is the best way to repair complicated hand injuries.
Transplantation of composite latissimus dorsi myocutaneous flap and vascularized fibula was performed primarily to repair the tibial defects in 12 cases and radial defects in 2 cases, both of which were associated with large-sized skin defects. The peroneal artery and vein of the fibula were anastomosed to the circumflex scapular artery and vein of the myocutaneous flap, the subscapular artery and vein, as the common vascular pedicle of the two transplants, are anastomosed to the nutrient vessels in the recipient site. Cross-bridge vascular anastomosis was used in 13 cases . All of tfe transplanted tissues survived, Follow-up revealed a good growthof the transplanted flaps, solid union between the transplanted fibulas and the host bones, and the good functional recovery of the repaired extremities. The operative indication and technique were introduced, ahd the merit of the repair ahd reliability of the cross-bridge procedure were discussed.
