Emergency debridement has long been the standard of care for open fractures of the tibia as infection is an important complication. In developing countries, patients are admitted to teaching hospitals 6 to 24 hours after their initial trauma. We sought to evaluate outcomes of nailing and correlations between the risk of infection and the delay in surgery. Materials and methods: Medical files of 48 men and 15 women with a combined total of 63 open fractures of the leg during a 12-year period were reviewed. The mean age was 29 years. Thirty-four type I and 29 type II open fractures according to the classification of Cauchoix and Duparc were treated with Küntscher nail after excision/debridement. Preoperative CRP was performed in 27 patients and in 22 cases it was positive. Twenty-six fractures were treated within a period of 6 to 24 hours, and a further 37 was operated on beyond 24 hours. The average waiting time before surgery was 2 days. Results: The infection was present in 11 patients (17.5%). We failed to establish any correlation between the time of treatment and the occurrence of infection for both type I and type II fractures treated during the same intervals with p = 0.244 (p > 0.05). But we established a correlation between the type of open fracture and the occurrence of infection with p = 0.01 (p < 0.05). There were 10 cases of infection among 22 cases of positive preoperative CRP. We couldn’t find a correlation between the positive value of the preoperative CRP and the occurrence of infection. Seven cases of infection were treated with appropriate antibiotherapy and early revision surgery. Four others cases complicated to bone infection (n = 2) and septic nonunion (n = 2). The average time of hospitalization was 22 days. The average time for fracture healing was 7 months. Conclusion: The rule of six hours is hardly applicable in our contexts. Our study showed no correlation between the preoperative period and the occurrence of infection.

Traumatic dislocation of the hip is quite rare and accounts for 2% - 5% of all dislocations. We report on a case of a bilateral posterior hip dislocation associated with symmetric acetabular fracture and two cases of infracotyloid dislocation. The report included 2 men and one woman. The mean age of patients was 33 years. All dislocations followed a road traffic accident. Non-operative closed reduction was achieved within 19 hours of admission. The average follow-up time was 15 months. The hips were stable, mobile, and painless;and there was no radiographic sign of avascular necrosis of the femoral head.

本文提出了一种基于查找表的宽带射频功率放大器动态非线性预补偿技术。该技术使用查找表来补偿射频功放的静态非线性,同时采用一个基于有限脉冲响应（FIR）的弱非线性滤波器来补偿射频功放的记忆效应。这个弱非线性FIR滤波器由两个具有不同输入的并联的线性FIR滤波器组成。本文使用一个3GPP-FDD WCDMA信号作为测试信号,采用一个具有45分贝毫瓦峰值输出的L波段推挽砷化镓场效应管功放来验证该动态非线性预补偿技术的性能。实验验证结果证明了所提出的预补偿技术可以有效地补偿射频功放的动态非线性。

目的探讨骨形态发生蛋白15(BMP15)基因多态性与复发性葡萄胎(RHMs)和习惯性流产(RSAs)的相关性。方法收集2012年10月-2013年9月在加拿大麦吉尔大学人类健康中心妇产科治疗的77例不同种族的RHMs和习惯性流产妇女的血液标本,采用基因外显子测序分析患者BMP15基因的多态性,并采用蛋白功能预测软件预测各SNPs对BMP15蛋白功能的影响。结果在BMP15基因2个外显子中共检测到5个错义突变和1个插入突变。其中在外显子1中检测到2个错义突变(p.S5R和p.N103S);在外显子2中检测到3个错义突变(p.L148P,p.A180T,p.H200Y)和1个插入突变,(***263dup)。通过预测,p.L148P突变可能会严重影响BMP15蛋白的活性进而影响卵巢功能,而p.S5R突变的影响相对较小,其余SNPs对BMP15蛋白功能基本无影响。结论 BMP15基因突变除了可能与RHMs和习惯性流产妇女的卵泡生成障碍及卵巢功能早衰相关,还可能导致葡萄胎恶变。

Infection after hip prostheses is a potentially devastating complication, and a serious medical and surgical challenge, especially when associated with Paprosky type III femoral bone loosening. Treatment is difficult and options are limited. We report on a 2-stage revision of 15 patients undergoing femur reconstruction with massive allografts. Materials and methods: This was a prospective study which included 15 patients (10 men and 5 women) with infected hip prosthesis, associated with Paprosky type III femoral proximal massive bone loss. The median age of patients was 64 years with a preoperative functional status score of 6. The average number of procedures to the same hip after the first arthroplasty was 6. All patients benefited from a 2-step surgery with massive allografts and locking prosthesis. The average follow-up time was 36 months. Results: Infection was monomicrobial in 14 cases;and was polymicrobial in 4 cases. Methicillin-resistant Staphylococcus epidermidis was the main bacteria (n = 10). The average C-reactive protein level before the second procedure was 2.3 ± 3.4. It was normalized in 8 cases. We recorded 13 cases of primary consolidation without another surgery, 3 cases of relapse, 2 traumatic dislocations and 2 fractures of the allograft. Conclusion: Hip prosthesis infection is a potentially catastrophic complication with significant negative ramifications for both the patient and the healthcare system. Massive allografts use in Paprosky III femoral defect remains very attractive for bone stock restoration and hip function improvement.

Synovial sarcoma originating from the kidney is extremely rare. A 13-year-old girl presented with a mild left flank pain of one-week duration, with no associated history of hematuria or any other systemic symptoms. Computed tomography (CT) demonstrated a 6 × 13 × 9 cm mass in the left kidney. No soft tissue or extrarenal masses were identified. The patient received a combined of treatment with doxorubicin and ifosfamide. A radical nephrectomy was performed in the left kidney with no complications. Postoperative pathology revealed post-chemotherapy residue of monophasic spindle cell synovialosarcoma of the left kidney. She received a combined treatment with doxorubicin and ifosfamide in concomittance with external radiation therapy. The patient was re-examined 4 months after surgery. An abdominal and pulmonary CT found no recurrence or metastasis.

Background: Williams-Beuren syndrome (WBS) is a rare multi-system genomic disorder, caused by 7q11.23 microdeletion with a prevalence of 1/7500 - 1/20,000 live births. Clinical phenotype includes typical facial dysmorphism (elfin face), mental retardation associated with a peculiar neuropsychological profile and congenital heart defects. Other signs are occasional like ocular, skeletal, renal and dental anomalies. Here in, we present 38 WBS Tunisian patients. Methods: All patients underwent a genetic consultation and in order to confirm the clinical diagnosis of WBS, fluorescent in situ hybridization (FISH) was applied on metaphase spreads using the dual color locus specific identifier WBS region probe (Vysis probe) that hybridized to the ELN and LIMK1 loci at 7q11.23 and to control loci D7S486 and D7S522 at 7q31. About 15 to 20 metaphases were analyzed for each case. Results: The mean age at diagnosis was 4 years and 4 months. All patients showed facial dysmorphism. 66% (23/35) have cardiovascular anomaly, peripheral pulmonary stenosis (10/35) is interestingly more frequent than the supravalvular aortic stenosis (7/35). Various degrees of mental retardation were present and a normal intelligence was found in three patients. The unique cognitive profile was found in all patients except one who had autistic disorders. Ocular anomalies (13/38) were less frequent than described, the skeletal anomalies too (12/38). Dental malformations were frequent (22/32). Idiopathic hypercalcemia was present in 50% of children less than one year (2/4). Conclusions: WBS was a rare disorder, cardinal signs (facial dysmorphism, mental retardation and cardiovascular defects) were found in our patients in the same proportions than described. The occasional clinical signs have proportion different of precedent reported like hypercalcemia, ocular and dental anomalies. The identification of the different clinical signs in WBS patients permits to establish a strategy of follow up.
