Long-term follow-up by video of cervical dystonia treated with botulinum toxin

We have analysed video recordings of 21 patients with cervical dystonia treated with botulinum toxin. Fourteen patients have a record both of their response shortly after injections were commenced and between four years five months and six years seven months later. Our analysis shows that the long term outcome is often better than the initial response. We suggest that chronic treatment with botulinum toxin allows different muscles to those initially injected to be identified as contributors to the dystonia. Subsequent injection of these muscles leads to further improvement. It implies that cervical dystonia is a more widespread disorder of motor control, rather than simply limited to a few muscles.     

Case-control study of risk factors for cervical neoplasia in Denmark. II. Role of sexual activity,reproductive factors,and venereal infections

Sexual, reproductive and venereal risk factors for cervical neoplasia were investigated in a population-based case-control study of 586 women with histologically verified, cervical squamous-cell carcinoma in situ, and 59 women with invasive squamous-cell cervical cancer, diagnosed from 1985 to 1986 in Copenhagen. Cases were identified from the computerized Danish Cancer Registry. An age-stratified control group (n=614) was drawn at random from the female population in the study area by means of the Danish Central Population Register. A structured questionnaire was mailed to cases as well as controls. Increasing number of sexual partners exerted a significant effect on the risk both for carcinoma in situ, and invasive cancer, independently of age at first intercourse and other potential confounders. Conversely, the association with early age at first intercourse became statistically insignificant after allowance for other risk factors, although an increasing risk was still observed with decreasing age at sexual debut. Early age at first episode with genital warts was a significant risk factor for carcinoma in situ, perhaps indicating a possible increased susceptibility of the cervix epithelium during adolescence. A history of genital warts was a good predictor of risk for carcinoma in situ, whereas a history of previous gonorrhea was associated with an increased risk for invasive carcinoma. Women with multiple births had a significantly increased adjusted risk, especially for carcinoma in situ, although some association was also observed with invasive cervical cancer. The study supports the hypothesis of cervical neoplasia being a sexually transmitted disease, and that carcinoma in situ and invasive cervical carcinoma, to a high degree, have similar patterns of risk factors.Drs Kjaer, Engholm, and Lynge are with the Danish Cancer Registry.

颈椎前路钢板椎间融合器系统治疗颈椎间盘突出症

颈椎前路手术在颈椎间盘疾病中已广泛应用，手术方法主要为颈前路减压加椎间植骨融合术。但不管是早期的自体骨融合的颈前路手术，还是后来进一步发展的颈前路钢板以及椎间融合器技术，都存在着诸如融合失败率高、植骨块移位、塌陷、螺钉断裂、钢板松动等并发症，造成手术疗效不佳以致于二次手术。自2002年2月-2004年1月采用颈椎间盘摘除、颈椎前路钢板椎间融合器（PCB）系统内固定、植骨融合术治疗颈椎间盘突出症后均无前述并发症的发生，疗效满意，现报道如下。     

LCT联合阴道镜检查对宫颈病变筛查的临床分析

目的:评价液基细胞学检查(liquid-based cytologic test,LCT)配合阴道镜检查对子宫颈病变的诊断价值。方法:收集2006年1月~2007年8月在我院妇科门诊就诊患者,采用LCT检测,对细胞学检查异常的1116例进行阴道镜检查及活检。结果:LCT异常者占10.15%,LCT和阴道镜对低度鳞状上皮内瘤变(LSIL)的检出率分别为65.45%和71.01%,高度鳞状上皮内瘤变(HSIL)为70.54%和84.50%,宫颈浸润癌(CC)为89.55%和92.53%。结论:细胞学筛查是诊断宫颈病变的重要方法,配合阴道镜下活检,能提高子宫颈癌前病变和宫颈早期浸润癌检出率,具有重要的临床意义。     

Ectopic cervical salivary glands

Summary Ectopic salivary glands in the neck are very unusual lesions. Generally they are localized to the oropharyngeal region, near the mandible and para-parotid lymph nodes. They occur occasionally on the anterior border of the sternocleidomastoid muscle in the soft tissues of the neck. We wish to report on a singular association of ectopic salivary glands with partial hearing loss, preauricular fistula, palatoschisis, anal fistula, and an arteria lusoria. Morphological, histological and embryological aspects are discussed.     

Convergence of occipital nerve and superior sagittal sinus input in the cervical spinal cord of the cat

Co-existence of facial and occipital pain may occur in occipital neuralgia, migraine and cluster headache; suggesting convergence of trigeminal and cervical afferents. Such convergence has been shown in humans and other animals, but the site and extent of this are uncertain. In anaesthetized adult cats, the superior sagittal sinus and occipital nerve were stimulated electrically, and extracellular recordings made in the dorsolateral area of the upper cervical cord using glass-coated tungsten electrodes. Of 49 units in 10 cats, 33 (67%) had input from the superior sagittal sinus and the occipital nerve. Thirteen (27%) had superior sagittal sinus input and 3 (6%) had occipital nerve input. Convergent receptive fields were identified mechanically in 7 units. These experiments in cats show convergent input from occipital nerve and superior sagittal sinus on dorsolateral area units in two-thirds of cases studied. This experimental site of trigeminocervical convergence may relate to referral of pain in occipital neuralgia and other headaches.     

Corpectomy for multi-level cervical spondylosis and ossification of the posterior longitudinal ligament

The choice of a surgical approach for multi-level cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) is still a controversial issue. While most of the surgeons are still performing decompression by laminectomy some are doing multi-level anterior decompression. Few neurosurgeons are performing decompression by corpectomy. We have treated 26 patients by median cervical corpectomy during the last 4 years. These patients were followed up for a mean period of 25 months. Twenty one (80%) patients had a good outcome, 2 patients remained unchanged and 3 expired. Review of the literature and our experience indicates that patients with CSM and OPLL should be operated by median cervical corpectomy (anterior approach).     

宫颈粘液中白细胞增多与不孕的关系研究
