Purpose: To evaluate the rate and onset of intraoperative and postoperative complications post-phacoemulsification. Methods: One hundred sixty-two eyes of 145 patients with uveitis who underwent phacoemulsification between 2006 and 2009 were identified through surgical record review. Fifty-nine eyes of 46 patients met the inclusion criteria. Hazard ratio (HR) and Kaplan-Meier survival probability were calculated for each class of uveitis. Results: Macular edema (ME) resulted to be associated to chronic postoperative inflammation (r?=?0.6; p?=?0.00) and mostly related to patients who presented more than one postoperative relapse/year (r?=?0.2; p?=?0.02). Fuchs uveitis resulted to be a risk factor for posterior capsule opacification (PCO) (HR 3.36 IC95%1.0-10.5; p?=?0.03). Hypotony and elevated intraocular pressure (IOP) were detected in the anterior uveitis group (0.02 EY). Conclusion: The HR to develop ME was significantly related to chronic anterior uveitis. PCO and elevated IOP are most frequent in Fuchs uveitis. The postoperative visual acuity result was good among all the uveitis groups. 相似文献

The contribution of the nucleus accumbens shell, the dorsal hippocampus, and the basolateral amygdala to contextual and explicit cue fear conditioning was assessed in C57BL/6 (C57) and DBA/2 (DBA) mice showing differences in processing contextual information associated with consistent but non-pathological variations in hippocampal functionality. Mice from both strains with bilateral ibotenic acid or sham lesions located in each area were introduced in a conditioning chamber and exposed twice to the pairing of a tone (2 x 8 s, 2000 Hz, 80 dB) with a shock (2 s, 0.7 mA). On the following day, mice were first exposed to the training context then to the tone in a different context. Freezing behaviour was scored in all situations. C57 showed more freezing to the context than to the tone whereas DBA showed more freezing to the tone than to the context. In C57, both nucleus accumbens and hippocampal lesions impaired acquisition of contextual fear conditioning but paradoxically improved acquisition of cue fear conditioning, whereas amygdala lesions disrupted performance in every task. In DBA, nucleus accumbens lesions, like amygdala lesions, impaired acquisition of both contextual and cue fear conditioning, whereas hippocampal lesions did not produce any effect. The parallelism between the effect of nucleus accumbens and hippocampus lesions in C57, and between the effect of nucleus accumbens and amygdala lesions in DBA points to a variability in nucleus accumbens function according to the strain specialization to develop context- or cue-based responding. 相似文献

During the last 20 years, various conservative surgical techniques have been proposed to treat larynx cancer. On the basis of our various experiences and of the ultrastructural data on the tissues treated with radiowaves, we decided to also use radiosurgery in operations under direct microlaryngoscopy. We select 18 patients suffering from epidermoid carcinoma. These patients had been referred to our ENT clinic at the Polichnico of Palermo between 1999 and 2001. The authors describe the surgical procedures used and emphasize the advantages of radiosurgery in the treatment of larynx cancer. 相似文献

Brucellosis is an infection due to Brucella species and is characterized by acute febrile illness, chilly sensations, sweats, weakness, generalized malaise, body aches and headache. The involvement of the nervous system is rare. A few cases have been reported with symptoms and sign of optic neuritis, meningoencephalitis, meningomyelitis and cranial nerve palsy. We report a case with culture proven neurobrucellosis who presented with diabetes insipidus along with systemic signs. Neuroimaging revealed multiple lesions in brain parenchyma, including the suprasellar region. Both diabetes and suprasellar lesions improved markedly with specific antibiotic therapy. 相似文献

Reentrant ventricular arrhythmias in the late myocardial infarction period in the dog. 13. Correlation of activation and refractory maps 总被引:7,自引:0,他引:7
Isochronal maps of ventricular activation were analyzed in dogs 3-5 days after ligation of the left anterior descending coronary artery utilizing a 64-channel multiplexer. Isochronal maps of the effective refractory period were determined from 62 epicardial sites and correlated with the activation maps. The ischemia occurring in the surviving epicardial layer prolonged refractoriness in a spatially nonuniform manner. The resulting pattern of refractoriness on the epicardial surface resembled concentric rings of isorefractoriness which increased in duration from the normal zone to the center of the ischemic zone. The formation of an arc of functional unidirectional conduction block occurred along the gradient of refractoriness and the exact location of the arc depended on the S1-S2 interval. When a short S1-S2 failed to induce reentry, fewer adjacent sites with sufficiently disparate refractoriness formed a smaller arc of block. A subsequent S3 encountered further nonuniformly shortened refractoriness (normal areas had shortened refractoriness greater than ischemic areas) and the arc of block was lengthened. This required a longer time for the wavefront to circulate around the arc. When it then reached the distal side of the arc, refractoriness had expired proximal to the arc and reentry occurred. Similarly, nonuniform shortening of refractoriness explained why one reentrant beat may or may not produce successive reentrant beats. Therefore, the spatial pattern of refractoriness forms the substrate for the arc of unidirectional conduction block that is fundamental to the development of ventricular reentry in this experimental model. 相似文献

A multicenter randomized open-label long-term sequential deferiprone–deferoxamine (DFP-DFO) versus DFP alone trial (sequential DFP-DFO) performed in patients with thalassemia major (TM) was retrospectively reanalyzed to assess the variation in the left ventricular ejection fraction (LVEF) [1]. 相似文献

ObjectiveTreatment options for dysphagia associated with multiple sclerosis (MS) are currently limited. In this study we investigated whether intraluminal electrical pharyngeal stimulation facilitates swallowing recovery in dysphagic MS patients.Patients and methodsTwenty dysphagic MS patients were randomized to receive 5 Hz “real” pharyngeal stimulation (10 patients) for 10 min or “sham” pharyngeal stimulation for 10 min (10 patients). Patients were evaluated by videofluoroscopic, and electromyographic examinations, and by the Penetration/Aspiration Scale (PAS) performed before (T0) and immediately after the last session of 5 consecutive days of electrical pharyngeal stimulation (T1), and then after two (T2), and four (T3) weeks of 5 consecutive days of pharyngeal electrical stimulation.ResultsPatients who received “real” stimulation showed a significant improvement in all the swallowing outcome measures as compared with those receiving “sham” stimulation.ConclusionsNo specific treatment for oro-pharyngeal dysphagia related to MS has been described to date. Our preliminary findings suggest a potential benefit of intraluminal electrical pharyngeal stimulation for the treatment of dysphagia caused by MS. 相似文献

This study concerns the morphological differentiation between double outlet right ventricle (DORV) and aortic dextroposition (AD) defects, namely tetralogy of Fallot and Eisenmenger anomaly. Indeed, despite the similar condition in terms of sequential ventriculo‐arterial connections, DORV and AD are two distinct morphological entities. It is proposed that the borderline between these two groups of malformations is represented by the specific insertion of the infundibular septum into the left anterior cranial division of the septomarginal trabeculation (or septal band) occurring in ADs and lacking in DORV. Furthermore, the spiraliform versus straight parallel arrangement of the great arteries in the two groups of anomalies is emphasized as an additional and distinctive morphological feature. Emphasis is also given to the association of straight parallel great arteries conotruncal malformations, DORV and transposition of the great arteries, with the asplenia type of heterotaxy laterality defects. Within this context, the absence of subaortic ventricular septal defect and concomitantly of spiraliform great arteries in the asplenia group of heterotaxy anomalies, as detected by this study, further substantiates our belief of not mixing collectively the ADs with the DORV in clinico‐pathological diagnosis.
