富血小板血浆与骨再生

急性臂丛神经炎是一种少见病,但人们往往认识不足,在早期,易被误诊为神经根型颈椎病或胸廓出口综合征。为了提高对本病的认识,降低误诊和漏诊率,本文就急性臂丛神经炎的诊断、鉴别诊断与治疗进行综述。1诊断名词与病因急性臂丛神经炎,病因尚未明了,但却有典型的临床特征。最初由Parsonage等[1]和Turner等[2]报道为肩胛带综合征和麻痹性臂丛神经炎,后被称之为:Parsonage-Turner综合征。其他诊断名词有:急性臂丛神经炎,神经源性肌萎缩,术后原发性臂丛神经炎等[3,4]。     

Axonal damage in the spinal cord of multiple sclerosis patients detected by magnetic resonance spectroscopy.

Axonal damage is a major factor contributing to permanent disability in patients with multiple sclerosis (MS); it has been extensively investigated in the brain using magnetic resonance spectroscopy (MRS). In this study, MRS was used to investigate the degree of neuronal damage in the cervical spinal cord in MS. Spectra were acquired from spinal cord and brain in 11 patients with MS (expanded disability status score [EDSS], range 2.5-7.0) and 11 controls. Brain lesion volume and spinal cord cross-sectional area were measured. Concentration of the neuronal metabolite N-acetyl-aspartate ([NAA]) was reduced in the spinal cord in MS patients relative to controls (reduced by 32%, P < 0.05), indicating significant neuronal damage. Additionally, the spinal cord was significantly atrophied in MS patients (15%, P < 0.001). No significant reduction in brain [NAA] was seen in the MS group. There were no correlations between clinical measures and cord atrophy or brain lesion volume on MRI; however, spinal cord [NAA] correlated with the cerebellar subscore of the neurological assessment (P < 0.005), while brain [NAA] correlated with disease duration (P < 0.05). MRS demonstrated cellular damage within the cord over and above the tissue atrophy seen by MRI. Combining MRI and MRS may therefore give a more complete picture of neurodegeneration in the spinal cord.     

颈椎病手术中脊髓损伤的原因及处理

目的探讨颈椎病术中脊髓损伤的原因及处理方法。方法我科2005年3月至2007年10月手术治疗279例颈椎病,对术中出现脊髓损伤的5例患者的临床资料进行回顾性分析。结果279例患者中5例发生脊髓损伤,发生率为1.79%。颈前路颈椎病手术中发生4例,后路单开门颈椎管扩大成形术中发生1例。经过清除血肿,甲基强的松龙等药物的及时治疗,5例患者逐渐恢复。结论颈椎病前、后路手术中均可能发生脊髓损伤,如能及时治疗,预后较好。

Reversible reorganisation of the motor cortical representation of the hand in cervical dystonia.

Previous work has suggested that there may be a widespread disturbance of motor control mechanisms in patients with cervical dystonia. In the present study, we used transcranial magnetic stimulation to investigate the topography of the corticomotor projection to the abductor pollicis brevis (APB) muscle in 10 subjects with idiopathic torticollis. Threshold-adjusted stimuli were delivered at multiple scalp sites during a low-level voluntary contraction of the APB, and maps were generated of motor evoked potential amplitude versus scalp site. The cortical maps for the APB on the side opposite to the direction of head rotation were displaced laterally or posteriorly in all subjects and reverted to a more normal position after botulinum toxin injection of the cervical muscles in 5 subjects. The findings point to a reversible reorganisation of the corticomotor representation of the hand on the same side as the sternocleidomastoid (SCM) muscle that is involved in producing the dystonia. These results provide further evidence for the involvement of cortical centres and for a more widespread abnormality of motor control mechanisms in focal dystonia. The findings also support the notion that head turning is chiefly mediated by the hemisphere ipsilateral to the direction of the head rotation by means of a corticomotor projection to the contralateral SCM.     

Adenoma malignum (minimal deviation adenocarcinoma) of the cervix responsive to hormonal treatment

Adenoma malignum (AM) is a rare variant of cervical adenocarcinoma with an unfavorable prognosis despite radiation therapy, surgery, or chemotherapy either alone or in combination. Hitherto, however, the effectiveness of hormonal therapy for this condition has not been evaluated. We report on a patient with cervical AM treated with progesterone before surgery. The progesterone therapy resulted in a complete clinical response and partial surgical response. Later on the treatment was changed to tamoxifen because of side effects of the progesterone treatment. The patient is still without evidence of disease 42 months after the start of the hormonal therapy. The progesterone receptor analysis on the biopsy was clearly positive. This is, to our knowledge, the first case of an AM responsive to hormonal treatment. Furthermore, this is the first case of an AM with bone metastases at the time of primary diagnosis.

Difficulties using the Franco-Italian Glossary in assessing toxicity of cervical cancer treatment

Shakespeare TP, Ferrier AJ, Holecek MJ, Jagavkar RS, Stevens MJ. Difficulties using the Franco-Italian Glossary in assessing toxicity of cervical cancer treatment. Int J Gynecol Cancer 1998; 8: 51–55
We assessed the toxicities of patients treated for cervical cancer using the revised Franco-Italian Glossary (FIG). A total of 69 separate complications were appraised in 47 patients; however, only 43.5% of these side-effects could be accurately graded. In all, 56.5% of toxicities could not be scored for a variety of reasons: (1) the FIG does not account for all possible complications of cervical cancer treatment; (2) some important toxicities are regarded as too minor to be graded; (3) subjective assessment of some side-effects did not allow consensus to be reached when assigning a grade; (4) we could not accurately score toxicities using the FIG in a retrospective manner. Previous studies utilizing the FIG retrospectively have noted few problems with its use, with no indication of the number of toxicities unable to be graded. In view of the inability to grade the majority of complications in the present study in an accurate manner, we conclude that the revised FIG requires detailed data that are best collected prospectively and that several minor modifications of the glossary should be considered. Results of studies using the glossary retrospectively should be viewed with caution.
