Diastematomyelia presenting as progressive weakness in an adult after spinal fusion for adolescent idiopathic scoliosis.

BACKGROUND CONTEXT: Diastematomyelia is uncommon and rarely presents in adulthood. This report draws attention to the fact that patients who underwent spinal fusion for deformity before the widespread use of computed tomography (CT) and magnetic resonance imaging (MRI) may have unrecognized spinal cord abnormalities. This should be considered if revision surgery is contemplated. PURPOSE: This case report focuses on the late presentation of lower-extremity weakness in a 44-year-old woman with a split cord malformation (diplomyelia), diastematomyelia and tethered cord syndrome. STUDY DESIGN/SETTING: METHODS: The patient underwent instrumented posterior spinal fusion with a Harrington rod as a child for progressive thoracolumbar scoliosis. As an adult, she developed paraparesis after a traumatic event.The patient underwent decompressive laminectomy, subtotal resection of the old fusion mass and resection of the osseous septum. Postoperatively, an anterior spinal fluid leak in the lower thoracic region required repeated fascial grafting, resection of a pseudomeningocele and reverse left latissimus dorsi flap transfer. The leak was controlled, and the patient had near complete resolution of her paraparesis 1 year after her surgery. RESULTS: The case described herein is unusual in that patients with diplomyelia and diastematomyelia rarely are symptomatic in adulthood. However, trauma may precipitate the onset of neurologic symptoms. This patient underwent spinal surgeries to address deformity, pain and progressive lower-extremity weakness. Preoperative CT and MRI studies showed a split cord malformation and diastematomyelia at L1-L2 with spinal stenosis and tethering of both hemicords. CONCLUSIONS: Progressive weakness without any previous neurologic deficit or neurocutaneous stigmas of an underlying spinal cord abnormality may develop in the adult with unrecognized diastemotomyelia. This case demonstrates that a thorough preoperative workup of patients with complex spinal deformities is imperative.     

羊间接性颞下颌关节损伤后髁突软骨中基质金属蛋白酶-3表达及其意义

目的 探讨基质金属蛋白酶-3(matrix metalloproteinase-3，MMP-3)在羊颞下颌关节((temporomandibular joint，TMJ))间接创伤后骨关节病发生中的作用。方法 用自制撞击装置造成山羊双侧颞下颌关节间接性创伤，分别于伤后1周、1，3，6个月取TMJ髁突软骨，并以正常TMJ作为对照，用免疫荧光组织化学方法观察MMP-3的表达。结果 TMJ髁突软骨中MMP-3伤后1个月表达开始增强，后期进一步增强；荧光着色于软骨破坏区及增生的滑膜样组织、软骨肥大带及骨髓内较强，正常对照组基本呈阴性反应。结论 MMP-3参与了TMJ创伤所致TMJ骨关节病过程，并起了重要作用。

Balloon dilation for ureteral stricture with stone fragments after ESWL]

We treated 5 cases of severe hydronephrosis with balloon dilation. Those hydronephrosis were due to the ureteral stricture with small stone fragments after ESWL (Lithostar). In each case, in situ ESWL had been done on a long-lodged ureteric stone with severe hydronephrosis. And even after the disintegration of stone with ESWL, hydronephrosis remained due to ureteral stricture with small stone fragments. Balloon dilation was done through percutaneous nephrostomy tract in 4 cases and via retrograde transurethral routine in 1 case. Balloon dilation catheter (7 fr. 6 mm diameter 4-10 cm length, Bard Co.) was used. There was no need for stone extraction. After dilation, ureteric stents (8.2/7 fr.) were kept in place for 4-8 weeks. Intravenous urogram was taken on 4-8 weeks after removing ureteric stents. In all of the 5 cases, improvement of hydronephrosis was remarkable. And there was no residual stone fragments in 4 cases. It is concluded that balloon dilation for ureteral stricture with stone fragments after ESWL is very useful. For the valid evaluation of balloon dilation, further experience and longer observation are requisite.
