Introduction The Guglielmi detachable coil (GDC) 360°, a new complex shaped bare platinum coil, became available in Europe for aneurysm
treatment in September 2005. The purpose of this study was to assess the feasibility and safety of selective embolization
of intracranial aneurysms with the GDC 360° in 52 consecutive patients.
Methods All patients included in this study were registered in a prospectively maintained database. We assessed the patient clinical
history, aneurysm shape and dimensions, technical details and complications of the procedures, degree of aneurysm occlusion,
and clinical findings upon discharge. In all patients, the first coil deployed was a GDC 360°.
Results Over a 6-month period, we intended to treat 52 aneurysms with the GDC 360° in 52 patients. Of these 52 patients, 42 (81%)
were treated in the context of subarachnoid haemorrhage. In 51 of 52 patients, the underlying aneurysm was successfully treated
by coil embolization. Six procedures (11.5%) were complicated by the formation of thrombus in the parent artery during the
intervention. One patient suffered a stroke related to the procedure. Angiograms obtained immediately after the procedure
showed complete occlusion of the aneurysmal sac in 38 of 51 procedures (74.5%), a neck remnant in 11 (21.6%), and a residual
aneurysm in 2 (3.9%). In 43 of 51 patients (84.3%), clinical assessment demonstrated independent clinical status, whereas
7 patients (13.7%) required assistance in the activities of daily living upon hospital discharge. One patient (2.0%) died
after development of a severe vasospasm 10 days after the endovascular procedure.
Conclusion The GDC 360° can be safely used for the endovascular occlusion of intracranial aneurysms. 相似文献

Stoquart GG, Detrembleur C, Palumbo S, Deltombe T, Lejeune TM. Effect of botulinum toxin injection in the rectus femoris on stiff-knee gait in people with stroke: a prospective observational study.
Objective
To study the effect of botulinum toxin type A (BTX-A) injection in the rectus femoris on the decreased knee flexion during the swing phase of gait (stiff-knee gait) in people with stroke.Design
Intervention study (before-after trial) with an observational design.Setting
Outpatient rehabilitation clinic and gait laboratory.Participants
Nineteen chronic hemiparetic adults presenting with stiff-knee gait.Intervention
Injection of 200U of BTX-A (Botox) into the rectus femoris.Main Outcome Measures
Before and 2 months after BTX-A rectus femoris injection: Stroke Impairment Assessment Set (SIAS), Duncan-Ely test, and an instrumented gait analysis.Results
Median SIAS score improved from 53 (range, 36−65) to 57 (range, 42−70) (signed-rank test, P=.005) and the Duncan-Ely score from 3 (range, 1−3) to 1 (range, 0−3) (P<.001). In gait analysis, mean (± standard deviation) maximum knee flexion improved from 26°±13° to 31°±14° during the swing phase (paired t test, P<.001), knee flexion speed at toe-off improved from 82°±63° to 112°±75°/s (P=.009), and knee negative joint power (eccentric muscular contraction) improved from −.27±.23 to −.37±.26W/kg (P<.001). The 4 patients who almost did not flex the knee (<10°) before the BTX-A rectus femoris injection did not improve after the injection. The other 14 patients who flexed the knee more than 10° before the BTX-A rectus femoris injection decreased the walking energy cost from 5.4±1.6 to 4.6±1.3J·kg−1·m−1 (P=.006).Conclusions
BTX-A rectus femoris injection may be beneficial in patients with a stiff-knee gait after stroke, particularly in patients with some knee flexion (>10°). 相似文献104.

Caty GD, Arnould C, Stoquart GG, Thonnard J-L, Lejeune TM. ABILOCO: a Rasch-built 13-item questionnaire to assess locomotion ability in stroke patients.
Objective
To develop a questionnaire (ABILOCO), based on the Rasch measurement model, that can assess locomotion ability in adult stroke patients (International Classification of Functioning, Disability and Health activity domain).Design
Prospective study and questionnaire development.Setting
A faculty hospital.Participants
Adult stroke patients (N=100) (age, 64±15y). The time since stroke ranged from 1 to 260 weeks.Intervention
A preliminary questionnaire included 43 items representing a large sample of locomotion activities. This questionnaire was tested on the 100 stroke patients, and their responses were analyzed using the Rasch model (RUMM 2020 software) to select items that had an ordered rating scale and fitted a unidimensional model.Main Outcome Measure
The ABILOCO questionnaire.Results
The retained items resulted in a 13-item questionnaire, which includes a wide range of locomotion abilities well targeted to the sample population, leading to good reliability (R=.93). The item calibration was independent of age, sex, time since stroke, and affected side. The concurrent validity of ABILOCO was also investigated by comparing it with well-known, criterion standard scales (Functional Walking Category, Functional Ambulation Categories, item 12 of the FIM instrument evaluating walking ability) and the walking speed measured with the 10-meter walk test.Conclusions
The ABILOCO questionnaire presents good psychometric qualities to measure locomotion ability in adult stroke patients. Its range and measurement precision make it attractive for clinical use throughout the rehabilitation process and for clinical research. 相似文献105.

Wavelength specific biological damage has been previously identified in human skin reconstructed in vitro. Sunburn cell and pyrimidine dimers were found after UVB exposure, and alterations of dermal fibroblasts after UVA exposure. These damages permitted us to discriminate UVB and UVA single absorbers. The present study shows that these biological effects can be obtained simultaneously by a combined UVB + UVA exposure using ultraviolet solar simulated light (UV-SSR), which represents a relevant UV source. In addition, the protection afforded by two broad spectrum sunscreen complex formulations was assessed after topical application. These two formulations displayed the same sun protection factor but different UVA protection factors determined by the persistent pigment darkening (PPD) method. Dose response experiments of UVA or UV-SSR showed that the preparation with the highest PF-UVA provided a better protection with regard to dermal damage compared to the other formulation. Using an original UVB source to obtain the UVB portion of SSR spectrum, the preparations provided the same protection. This study strikingly illustrates the fact that the photoprotection afforded by two sunscreen formulations having similar SPF values is not equal with regard to dermal damage related to photoaging. 相似文献

Background
The locus coeruleus/subcoeruleus complex (LC/LsC) is a structure comprising melanized noradrenergic neurons.Objective
To study the LC/LsC damage across Parkinson's disease (PD) and atypical parkinsonism in a large group of subjects.Methods
We studied 98 healthy control subjects, 47 patients with isolated rapid eye movement sleep behavior disorder (RBD), 75 patients with PD plus RBD, 142 patients with PD without RBD, 19 patients with progressive supranuclear palsy (PSP), and 19 patients with multiple system atrophy (MSA). Twelve patients with MSA had proven RBD. LC/LsC signal intensity was derived from neuromelanin magnetic resonance imaging using automated software.Results
The signal intensity was reduced in all parkinsonian syndromes compared with healthy control subjects, except in PD without RBD. The signal intensity decreased as age increased. Moreover, the signal intensity was lower in MSA than in isolated RBD and PD without RBD groups. In PD, the signal intensity correlated negatively with the percentage of REM sleep without atonia. There were no differences in signal intensity between PD plus RBD, PSP, and MSA.Conclusions
Neuromelanin signal intensity was reduced in all parkinsonian disorders, except in PD without RBD. The presence of RBD in parkinsonian disorders appears to be associated with lower neuromelanin signal intensity. Furthermore, lower LC/LsC signal changes in PSP could be partly caused by the effect of age. © 2023 The Authors.
