蜡泪样骨病1例报告

1968年瑞典Elekta公司研制成世界上第一台γ-刀，30余年来，全球已陆续建立起130个左右治疗研究中心。国内16台旋转式头部γ-刀累计治疗病人万例以上。这种立体定向放射技术的推广，避免了手术之“短”，发扬了手术之“长”，不必开刀，胜似开刀，两全其美。本文从以下几个方面谈谈体会。

儿童蜡泪样骨病2例报告及X线分析

蜡泪样骨病（MelorhostosisLeri）为一种罕见的骨质硬化性疾病，属于发育不良性骨病中骨硬化症的一种，又名肢骨纹状增生症、单侧象牙性骨质增生症、单肢流波状骨质增生症等，好侵犯单一肢体，增生的骨质自上而下沿骨干一侧向下流注，很象蜡烛表面的烛泪，故命名为蜡泪样骨病或烛泪骨。本症由Leri氏于１９２８年首先报告，故又称为Leri氏病。我院曾诊治两例蜡泪样骨病，现报道如下。１一般资料１．１例１男性，８岁，因右手中、环指屈曲挛缩伴疼痛１年就诊。行X线右手正斜位片检查，发现右手第３、４掌骨及中指近、中节指骨，环指诸指骨骨…

蜡油骨病1例

患者女性,16岁。因走路时跌倒左膝疼痛1天来院。自述曾是校运动员,于3年前跑步时跌倒,左膝髌骨外移。在当地医院就诊行手法复位,并拍膝关节X光片示左侧髌骨及胫骨上端、股骨下端高密度影,但未予特殊治疗。此后受轻度外力即出现左侧髌骨移位。查体:双下肢无畸形,左膝关节浮髌试验可疑阳性,化验室检查无异常。MRI检查示:左侧股骨下端、胫骨上端、髌骨内可见蚯蚓状无信号灶,边缘光滑锐利,左侧股骨下段、胫骨上段部分骨皮质呈条带状增厚。髌上囊及关节腔内见长T1长T2液性信号影(图1,2)。考虑为骨质硬化,不除外蜡油骨病,建议X线进一步检查。X…     

A case of melorheostosis with a 14-year follow-up

Melorheostosis is a benign sclerosing dysplasia with a very unusual and characteristic roentgenographic appearance. We reported a patient with melorheostosis in the left lower extremity followed up for 14 years. Although the extraosseous lesions only slightly enlarged, the bone scintigraphy showed the activity of the metabolism to be still high.     

Stretch- and H-reflexes of the lower leg during whole body cooling and local warming

BACKGROUND: This study was undertaken to evaluate if possible changes in stretch- and H-reflexes could be related to the changes in the EMG activity of the cooled lower leg muscles observed during a stretch-shortening cycle exercise. METHODS: Eight subjects wearing shorts and jogging shoes were exposed once to 27 degrees C and twice to 10 degrees C for 60 min each. During the second exposure to 10 degrees C, the subject's lower legs were kept warm (10 degrees Clw) with electrical pillows. After the exposures Achilles tendon reflex (stretch reflex) was induced and the EMG activity of the triceps surae was measured. Immediately after reflex measurements the EMG activity of the triceps surae and tibialis anterior during a drop-jump (stretch-shortening cycle) was measured. After similar thermal exposures electrically induced H-reflex from the calf was measured. RESULTS: During the preactivity and stretch phases the EMG activity of the triceps surae increased after the exposure to 10 degrees C, whereas during the shortening phase it decreased. During the shortening phase cooling, on the contrary, increased the activity of tibialis surae anterior. These changes disappeared at 10 degrees Clw. At 10 degrees C the maximum EMG-amplitude of triceps surae during stretch reflex decreased (p<0.05), reflecting suppressed muscle spindle activity. Suppressed spindle activity causes the agonist to be unfacilitated and the antagonist muscle contraction to be uninhibited, which was seen in the present study as decreased agonist and increased antagonist EMG activity during the shortening phase at 10 degrees C. The Hmax/Mmax-ratio, H-reflex latency and amplitude increased at 10 degrees C (p<0.05), reflecting increased motoneuron pool excitability. This in part may explain the increased EMG activity during the preactivity and stretch phases. CONCLUSION: Cooling-induced increase in the excitability of the motoneuron pool and suppression of muscle spindle activity seem to be responsible of the EMG activity changes during the stretch-shortening cycle, consequently decreasing muscular performance.     

Glomangiomatosis of the lower leg

This paper demonstrates a case of multiple glomangiomas, or glomangiomatosis, including clinical presentation, imaging appearances, and subsequent management. Differentiating features from typical glomus tumors are described. To the best of our knowledge, this is the first reported case of a glomangioma involving the distal tibiofibular syndesmosis.     

小腿脂肪肉瘤1例

患者 男，78岁，发现左小腿后外侧肿物2个月。体检：左小腿后外侧触及一中等硬度包块，表面光滑，皮温略高，皮静脉怒张，肿物张力较大，基底摸不清。实验室检查无异常。     

Giant schwannoma of the lower leg

Schwannomas are relatively common, benign, peripheral nerve sheath tumours. They usually range in size from 2 to 20 cm, but when localised in the lower legs the maximum length is less than 10 cm. The case reported here was a giant fusiform schwannoma of the left fibular nerve with a length of 25.5 cm. In contrast to the usual findings of giant schwannomas, no cystic, haemorrhagic or necrotic changes could be found by ultrasonography, computed tomography or magnetic resonance imaging. The combination of tumour size, location and radiological presentation is very unusual and, to our knowledge, has never been reported before in the literature.
