ObjectivesTo investigate the subcortical somatosensory evoked potentials (SEPs) to electrical stimulation of either muscle or cutaneous afferents.MethodsSEPs were recorded in 6 patients suffering from Parkinson’s disease (PD) who underwent electrode implantation in the pedunculopontine (PPTg) nucleus area. We compared SEPs recorded from the scalp and from the intracranial electrode contacts to electrical stimuli applied to: 1) median nerve at the wrist, 2) abductor pollicis brevis motor point, and 3) distal phalanx of the thumb. Also the high-frequency oscillations (HFOs) were analysed.ResultsAfter median nerve and pure cutaneous (distant phalanx of the thumb) stimulation, a P1-N1 complex was recorded by the intracranial lead, while the scalp electrodes recorded the short-latency far-field responses (P14 and N18). On the contrary, motor point stimulation did not evoke any low-frequency component in the PPTg traces, nor the N18 potential on the scalp. HFOs were recorded to stimulation of all modalities by the PPTg electrode contacts.ConclusionsStimulus processing within the cuneate nucleus depends on modality, since only the cutaneous input activates the complex intranuclear network possibly generating the scalp N18 potential.SignificanceOur results shed light on the subcortical processing of the somatosensory input of different modalities. 相似文献

We describe the use of a double-strand peroneus brevis allograft to reconstruct the coracoclavicular and acromioclavicular (AC) joint ligaments. Through sharp dissection, the distal clavicle, the AC joint, and the torn superior AC and coracoacromial ligaments are identified. The coracoid process and injured coracoclavicular ligaments are identified with blunt dissection. A 1-cm segment of the lateral clavicle is resected. Vertical and connecting horizontal tunnels are created (4.5 mm) in the lateral clavicle and in the medial acromion process. The 5.5- to 6.0-mm-diameter allograft is looped around the coracoid process, and both strands are passed through the vertical clavicle tunnel with a nitinol wire loop. One strand passes through the vertical clavicle tunnel, and the other strand passes through the horizontal tunnel, exiting through the lateral end. The allograft strand passed through the vertical clavicle tunnel is then passed inferiorly through the superior vertical acromion tunnel, and the strand passed completely through the horizontal clavicle tunnel is passed laterally through the medial horizontal acromion tunnel. After both strands exit inferiorly through the vertical acromion tunnel, they are tensioned and sutured with AC joint reduction. Soft tissue closure uses No. 0 and No. 2-0 absorbable sutures with No. 3-0 nylon sutures at the skin. 相似文献

The purpose of this study was to review the clinical results of 5 patients who underwent repair of a chronic Achilles tendon rupture using a combination of peroneus brevis transfer and plantaris tendon augmentation. The technique belongs to the group of local tendon transfer procedures making use of the transferred peroneus brevis tendon as strengthening material together with the plantaris tendon as suturing material. There were 4 males and 1 female with an average age of 49.4 years and an average time to presentation postinjury of 19.8 weeks (range 5-40 wk). All patients underwent Cybex strength testing before and approximately 1 year after surgery. This testing demonstrated a postoperative improvement in peak plantarflexion torque (Newton-meters/body weight) in all cases. The peak torque of plantar flexion increased in all patients (range, 21%-410%). Four patients were found to have an increase of the dorsal flexors peak torque (range, 31%-290%), whereas one patient showed a decrease (-37%). No patient experienced wound closure complications, postoperative pain, or functional limitations. In spite the possibility of residual lateral ankle instability, we found this modification to be a valuable innovation that offers a very good functional result, low morbidity, technical advantages to the surgeon and, most important, a durable and satisfactory result for the patients. 相似文献

The objective of this study was to investigate the incidence and density of Demodex folliculorum in the patients with rheumatoid arthritis (RA). Forty-one patients with RA and twenty-seven age and sex matched healthy controls
were enrolled in this study. Disease Activity Score (DAS 28) was used for the assessment of disease activity. Out of 41 patients,
33 were females and 8 males. The mean disease duration was 10.9 ± 8.2 years. The mean DAS 28 was 3.8 ± 1.2. No statistically
significant differences in the incidence and density of Demodex mites were found between patients with RA and controls. Although immunosuppression is thought to be a risk factor for the
D. folliculorum infestation no such correlations could be found in the 41 immunosuppressed patients with RA, therefore, further studies with
larger groups are needed. 相似文献

根据54侧成人尸体肘部桡管,旋后肌管及桡神经深支在肘部行程的解剖学研究,特别观察到桡侧腕短伸肌纤维桥有90.6%为全腱性,其中有88.9%与旋后肌弓外侧半重叠直接紧邻桡神经深支,认为该纤维桥是桡神经深支在肘部卡压的主要因素。并注意到桡神经深支与桡骨头部位的关节囊等关系密切,提示临床医生注意。 相似文献

Rosacea and cutaneous lupus erythematosus (CLE) are chronic inflammatory dermatoses. To our knowledge, no cases of granulomatous rosacea (GR) associated with CLE have been previously reported in the literature. We describe the case of a 38-year-old female patient who presented to our clinic with a diffuse scaly facial erythema, with the codiagnoses of GR and CLE later confirmed with clinicopathological correlation. 相似文献
