Abstract

A microsurgical drezotomy can be useful in some selected cases for the treatment of severe and diffuse spasticity in one or several limbs. This technique has been introduced by M. Sindou in 1972, on the basis of human anatomical studies in the dorsal root entry zone (DREZ). The aim of surgery is to interrupt preferentially the peripheral inputs sustaining myotatic and polysynaptic reflexes which are exaggerated in spasticity, and also nociceptive fibers in the lateral part of the DREZ, whilst sparing most of the medial tactile and kinestetic fibers for the dorsal funiculus. The authors report a retrospective review of 269 patients with severe spasticity in one upper limb (94 cases) treated by a cervical drezotomy, and in one (17 cases) or two lower limbs (158 cases) treated by a lumbosacral drezotomy. The place of this ablative technique inside the neurosurgical armament against spasticity is discussed.

The potential for utilizing inter-limb coupling in the rehabilitation of upper limb motor disability due to unilateral brain injury.

PURPOSE: Symmetry tendencies in human movement have generally been regarded as a constraint to upper limb motor performance. However, several recent studies have suggested that this phenomenon might be utilized in the rehabilitation of individuals with motor disability due to unilateral brain injury. In this paper the efficacy of such a rehabilitative approach is explored by reviewing: (i) examples of symmetry tendencies in healthy individuals, (ii) the potential neurophysiological mechanisms responsible for inter-limb coupling, and (iii) recent studies which have directly assessed the effects of inter-limb coupling on individuals with unilateral brain injury. METHOD: A thorough review of current published evidence was conducted utilizing various electronic search engines (Medline, PreMedline, Embase and Cinahl). Studies included those that focused on symmetry tendencies and/or inter-limb coupling in the upper limbs with a particular emphasis placed on studies of individuals with unilateral brain injury. RESULTS: Based on the current literature it seems that motor function of the affected upper limb in individuals with unilateral brain injury can be improved through a rehabilitation approach that incorporates inter-limb coupling. CONCLUSION: This approach should be considered as an adjunct to more common rehabilitation strategies with future research aimed at determining the most effective means of employing this paradigm.

[Conservative and functional management for soft tissue sarcomas of the extremities: role of radiotherapy].

Recent publications have permitted to quantify the benefit of radiotherapy in the conservative treatment of soft tissue sarcoma of the limbs. The aim of this review is to focus on aspects of radiotherapy witch influence local control and functional outcome for early and late normal tissue damage. The evaluation of late effects is performed according to Soma-Lent (Subjective-Objective-Management-Analytic-Late Effects of Normal Tissues) classification. About complications, neurological complications are probably under estimated and are related to total dose of radiation therapy.

Durometry for the assessment of skin disease in systemic sclerosis.

OBJECTIVE: To examine the validity of a durometer to objectively measure skin hardness in systemic sclerosis (SSc), and to compare digital durometry with the modified Rodnan skin score (MRSS) and ultrasonography. METHODS: Patients with SSc and healthy controls underwent durometry measurements in 3 assessments: a Latin square experiment to establish durometry's intra- and interobserver reliability compared with skin scoring (5 SSc, 1 control); a longitudinal cohort to assess sensitivity to change in skin hardness (13 SSc, 5 controls); and an ultrasound cohort to evaluate correlation between durometry, ultrasound-measured skin thickness, and clinical skin scoring (30 SSc, 12 controls). RESULTS: Intraobserver reproducibility was higher for durometry than for clinical skin scoring (intraclass correlation coefficient [ICC] 0.97 versus 0.85), whereas interobserver reproducibility was similar (0.75 versus 0.73). Interobserver reproducibility of durometry was good for all body areas (ICC 0.61-0.85), but for skin scoring it was moderate in the legs (0.51) and poor in the abdomen (0.08), feet (0.09), and fingers (0.27). Durometry scores correlated with clinical skin scores (Latin square: r = 0.44, P = 0.03; longitudinal cohort: r = 0.81, P < 0.001) and ultrasound-measured skin thickness (hands: r = 0.58, forearms: r = 0.63, upper arms: r = 0.40; P < or = 0.001 for all). Uninvolved skin in patients with SSc was harder than skin from controls (mean +/- SD 23 +/- 7 durometer units [DU] versus 19 +/- 6 DU; P < 0.0001). Finally, there was a strong correlation between change in MRSS and change in durometry score (r = 0.77, P = 0.002). CONCLUSION: Durometer-measured skin hardness correlates well with MRSS and ultrasound-measured skin thickness, provides greater reliability than MRSS, and is sensitive to changes in skin hardness over time. Durometry should be considered for use in clinical therapeutic SSc trials.
