Diagnosis of Atlantoaxial Subluxation in Morquio's Syndrome and Spondyloepiphyseal Dysplasia Congenita 总被引:1,自引:0,他引:1
Eiji Takeda M.D. Toshiaki Hashimoto M.D. Masanobu Tayama M.D. Masahito Miyazaki M.D. Etsuhisa Shirakawa M.D. Yoshiro Shiino M.D. Takahiko Saijo M.D. Michinori Ito M.D. Etsuo Naito M.D. A.H.M. Mahbubul Huq M.D. Yasuhiro Kuroda M.D. 《Pediatrics international》1991,33(5):633-638
Compression of the spinal cord due to atlantoaxial subluxation was diagnosed in a patient with Morquio's syndrome and in another with spondyloepiphyseal dysplasia (SED) congenita by cervical radiography and magnetic resonance imaging (MRI). The patient with Morquio's syndrome, a 15 year old boy, had no neurologic symptoms and his somatosensory evoked potential (SSEP) was normal. However, MRI demonstrated spinal cord compression at C1-C2. In contrast, the patient with SED congenita, an 11 year old girl, had neck pain, hyperreflexia and loss of vibration sense in both legs. These findings were explained by the absence of P3 and later waves in SSEP and by compression of the spinal cord observed on MRI. Both SSEP and MRI should be used for evaluating disorders in which atlantoaxial subluxation might be present. 相似文献

目的观察小切口手术治疗晶状体脱位继发青光眼的临床疗效。方法回顾性研究自1999年4月至2005年2月在我院因晶状体脱位继发青光眼而行小切口白内障手术治疗的一组患者共21例22只眼。记录患者眼压、视力变化及术中术后并发症等。观察时间为3-72个月。结果22只眼术后最后一次复查时平均眼压为(12.47±3.77)mmHg,明显低于术前平均眼压(42.29±18.99)mmHg,差异有非常显著意义(t=7.185,p=0.000)。22只眼术后最后一次复查最佳矫正视力在NLP~1.2之间,较术前有明显改善,差异有非常显著意义(t=-2.929,p=0.008)。术中术后均未出现严重并发症。结论小切口晶状体手术是治疗晶状体脱位继发青光眼的有效手术方式,且技术较成熟,临床上如有条件应广泛开展。 相似文献

Book reviews in this article: Abnormally shaped, usually double-layered, patellae are recognized as occurring in multiple epiphyseal dysplasia. The case described is unusual in that an associated defect appeared in the femur and resulted in mechanical symptoms. 相似文献

The posteroanterior and lateral wrist radiographs of 52 adults who sustained acute distal radial fractures were reviewed to
determine the incidence of radiographic signs of concomitant acute scapholunate ligamentous injury. Three radiographic criteria,
either separately or in concert, were used to identify scapholunate ligamentous injury. They are (a) scapholunate angle >60°;
(b) widening of the scapholunate space >2 mm; and (c) the cortical ring sign (also called the scaphoid or signet ring sign).
Thirty-six of 52 cases (69%; 95% confidence interval =52.1–82.2%) showed evidence of scapholunate ligamentous injury; 16 of
52 cases (31%; 95% confidence interval =16.8–46.6%) showed no evidence of scapholunate ligamentous injury. Statistical analysis
suggests that a minimum of 52.1% of all adult distal radial fractures are associated with signs of concurrent acute scapholunate
ligamentous injury. The analysis also suggests that independent variables such as age, gender, severity of radius fracture,
or mechanism of injury do not significantly alter the incidence of associated carpal ligamentous instability.
This study has established a greater than 52.1% incidence of radiographic signs of scapholunate instability in adults with
acute distal radial fractures. It is incumbent upon radiologists to search for the signs of scapholunate dissociation in all
adult cases of distal radius fracture, regardless of age, gender, severity of radius fracture, or mechanism of injury. 相似文献

Grisel’s syndrome is a rare condition of uncertain etiology characterized by a non-traumatic atlanto-axial subluxation, secondary to an infection in the head and neck region. The authors discuss the history, pathogenesis, terminology, classification, clinical characteristics, diagnosis, treatment, prognosis and prevention of this syndrome. 相似文献

The authors report a case of longitudinal tendon tears of the peroneus longus and brevis in the presence of tophaceous gouty infiltration. There are a limited number of reports discussing similar processes affecting various tendons throughout the body. There has been 1 prior case of peroneal tendon involvement affecting only the peroneus brevis. A 35-year-old man presented with a 4-year history of left-sided lateral ankle pain, redness, and swelling. The patient described the "attacks" as occurring off and on, with a recent increase in frequency. The symptoms were relieved with indomethacin, colchicine, and narcotic analgesics. Upon clinical evaluation, there was a cavus foot type with moderate calcaneal varus. Peroneal subluxation was elicited with resisted eversion. An MRI evaluation revealed longitudinal tears of both peroneal tendons. During surgical repair, a chalky-white substance resembling gouty tophi was present within both tendon tears. The tendons were remodeled and repaired. The patient had an uneventful postoperative course with nearly completed resolution of his symptoms at 1-year follow-up. The patient was referred to his primary care physician for further evaluation and long-term control of elevated uric acid levels. 相似文献

A 2 year old boy withhumero-spinal dysostosis is described. This is the third case of this disease reported in the literature.Humero-spinal dysostosis is characterised radiologically by distal humeral bifurcation, elbow subluxation and coronal cleft vertebrae. Congenital, progressive heart disease, possibly with fatal outcome, is probably part of the syndrome. 相似文献
