Retinopathy of prematurity (ROP) has become the leading blinding eye disease in children worldwide. In recent years, the recognition and treatment of acute stage lesions have achieved remarkable results. Fundus lesions could spontaneously regress in most of children with ROP, while the understanding of the law of spontaneous regression is still very limited. Although the fundus morphology is significantly improved after spontaneous regression, the long-term prognosis of visual function is not optimistic. The introduction of new technologies such as fundus fluorescence angiography and optical coherence tomography and angiography will help further understanding the nature of the spontaneous regression. To increase the study about spontaneous regression of ROP, which has significance for rationally arranging an economical and efficient screening time, formulating a scientific and individual treatment and follow-up plan, and improving the prognosis of visual function.
ObjectiveTo analyze the causes and characteristics of massive hemorrhage secondary to percutaneous nephrolithotomy (PCNL) and assess the value of superselective renal artery embolization in the management of this condition. MethodsThe imaging data and prognosis of 28 patients who developed repeated massive hemorrhage secondary to PCNL and underwent superselective renal artery embolization between April 2005 and June 2013 were reviewed. ResultsFollowing superselective renal artery embolization, hemorrhage was effectively controlled in all the 28 patients. Follow-up lasted from 6 to 62 months, averaging 41.6 months. No hematuria or other complications occurred during the follow-up period. ConclusionSuperselective renal artery embolization is safe and effective in managing massive hemorrhage secondary to PCNL, and it may be used as a preferred treatment for patients who are refractory to expectant treatments.
目的 研究巩膜外垫压手术联合视网膜激光光凝对硅油眼视网膜脱离的治疗效果。 方法 回顾性分析2009年1月－2012年1月，用巩膜外垫压联合视网膜光凝手术治疗36例硅油眼视网膜脱离的视网膜复位效果。 结果 全部患者均顺利完成巩膜外垫压手术及随后的视网膜激光光凝，行巩膜外放液5只眼，手术中未发生视网膜嵌顿、眼内出血和眼压显著升高等并发症；手术后1周视网膜复位21只眼（58.33%），剩下15只眼1个月后复位7只眼（19.44%），视网膜脱离总复位率为28只眼（77.77%）；未复位8只眼（22.23%），改用玻璃体切割手术方式，视网膜成功复位；6个月后取出硅油，随访6个月视网膜无脱离或者脱离范围增加；手术后眼压≥30 mm Hg （1 mm Hg=0.133 kPa）3只眼，≥20 mm Hg 7只眼，对症治疗1周后眼压均恢复到正常范围。 结论 巩膜外垫压联合视网膜激光光凝治疗硅油眼视网膜脱离，手术简单，复位率高，可为硅油眼视网膜脱离首选手术方式，对于巩膜外垫压手术失败和复杂的硅油眼视网膜脱离，应当选择玻璃体切割手术方式。
目的 探讨胰十二指肠切除术中引流管的放置与术后管理的方法。方法回顾性分析88例胰十二指肠切除术后管理经验。结果 术后腹腔并发症的发生率为10.2%(9/88)，胃排空障碍发生率为3.4(3/88)%，其中保留幽门胰十二指肠切除术后胃排空障碍发生率为5.5%(3/55)。结论 胰十二指肠切除术后腹腔引流是预防术后并发症的重要方法，术中合理放置引流管，术后加强腹腔引流的管理，能减少术后并发症的发生。
【Abstract】 Objective To introduce a new method using calcium phosphate cement/Danshen drug del ivery systemfor avascular necrosis of femoral head and to evaluate its cl inical outcome. Methods From May 2000 to June 2005, 48 patients (54 hips) with avascular necrosis of femoral head were treated with calcium phosphate cement/Danshen drug del ivery system implantation in the involved femoral head. There were 32 males(36 hips) and 16 females(18 hips) with an average age of 38.7 years (26-62 years). Twenty-one cases had the history of drinking or smoking, 15 cases had the history of receiving hormonotherapy and 2 had the history of injury in hip joint. The disease course was 2-32 months. According to standard of Association Research Circulation Osseous (ARCO) staging, 9 hips were classified as stage I, 31 as stage II and 14 as stage III. The operation consisted of removal of necrotic bone under weight-loading cartilage and the implantation of calcium phosphate cement/Danshen drug del ivery system, all mani pulations were done through a bone tunnel in trochanter. The function of hi p joint were evaluated and X-ray films were taken pre- and post-operatively. Results No phlebothrombosis of leg and foreign body action occurred in all cases, and incision healed by first intention. The postoperative follow-up averaged 42.5 months, ranging from 22 to 73 months. According to the evaluation criterion of Dandong 1995 for adult avascular necrosis of femoral head, the results were excellent in 33 hi ps, good in 17, fair in 3 and poor in 1, the excellent and good rate was92.6 %. Conclusion This method is relatively simple with less invasion, it not only improves the microcirculation of femoral head by local appl ication of traditional Chinese medicine, but also provide mechanic buttress in the weight-loaded area, which is beneficial to repair and reconstruction of femoral head. It may be a choice of minimally invasion surgery for femoral head necrosis.
Objective To investigate the perioperative management and the results of surgical treatment of spinal tuberculosis associated with diabetes mellitus. Methods The cl inical data were analysed retrospectively from 42 patients with spinal tuberculosis associated with type 2 diabetes mell itus who were surgically treated between July 2001 and January 2009.There were 22 males and 20 females with an average age of 56.5 years (range, 41-78 years). The disease duration was 4-18 months (mean, 7.5 months). The involved vertebrae included 2 cervical vertebrae, 13 thoracic vertebrae, 17 thoracolumbar vertebrae, and 10 lumbar vertebrae. Of them, 18 patients compl icated by paraplegia, and 25 patients had more than one of concomitant diseases. Anterior debridement and bony grafting with anterior instrumentation fixation were performed in 16 patients; anterior debridement and bony grafting with posterior instrumentation fixation in 4 patients; posterolateral costotransversectomy debridement and interbody fusion with posterior instrumentation fixation in 8 patients; posterior debridement and bony grafting with posterior fixation in 7 patients; sinus resectomy and focus debridement in 2 patients; anterior debridement and bony grafting in 3 patients; and CT guided percutaneous catheter drainage in 2 patients. Postoperative anti-tuberculosis treatment was given for 12-24 months. Results The patients were followed up 1.5-5.0 years, with a mean period of 3.5 years. One patient died of pulmonary infection after 1 week of operation; 1 patient died of myocardial infarction after 2 years of operation; and other patients survived without tuberculosis recurrence. Among 38 patients who received bony grafting, 34 patients achieved bony fusion, 3 suffered bony grafting failure without kyphotic deformity or instabil ity except 1 patient who died from pulmonary infection. Among 18 cases compl icated by paraplegia, nerve function improved to a certain extent. The intraoperative and postoperativecompl ications occured in 28 cases. The systemic compl ications mainly included heart insufficiency in 5, heart rrhythmia in 3, pulmonary infection in 2, urinary tract infection in 2, and stree ulcer in 1; they were cured after medical treatment. The local complications mainly included sinus tract formation in 5, pleural tear in 2, neurologic injury in 2, intraoperative tear of inferior vena cava in 2, and the loosening of transpedicular screws in 4; they all were cured effectively. Conclusion Surgical treatment of spinal tuberculosis associated with diabetes mell itus appears to be a beneficial procedure on the condition that the blood glucose is controlled and the associated disorders and postoperative complications are properly handled, and reasonably selection of surgical procedures is very important. Instrumentation fixation provides adequate stabil ity to allow early mobilization.
