    Cortical Dysplasia: Electroclinical, Imaging, and Neuropathologic Study of 13 Patients

    EPILEPSIA, Issue 9 2001
    Laura Tassi
    Summary: ,Purpose: The aim of this study was to correlate the electroclinical and radiologic data with the neuropathologic findings and surgical outcome in epileptic patients with epilepsy and Taylor's focal cortical dysplasia (TFCD) and to characterize further the abnormal intermediate filaments expression in the balloon cell present in the peculiar dysplasia. Methods: We retrospectively selected 13 TFCD patients who underwent surgery for intractable epilepsy with the aim of removing the magnetic resonance (MR)-detectable lesion and/or the epileptogenic zone defined by stereoelectroencephalographic recordings. The surgical specimens were analyzed by means of routine neuropathologic and immunocytochemical studies. Antisera against different intermediate filaments also were used in serial adjacent sections to evaluate their coexpression in balloon cells. Results: Histopathologic abnormalities typical of TFCD were found not only within the MR-visible lesions but also in most of the epileptogenic zones with no MR signal alterations. Furthermore, the MR-visible lesions contained a high proportion of cells with an abnormal expression of intermediate filament proteins. After a long follow-up, 10 of the patients are now seizure free. Conclusions: Our findings indicate that highly epileptogenic zones may correspond to tissue alterations not revealed by neuroimaging. Furthermore, the immunocytochemical data show that the dysplastic tissue detected by MR contained high concentrations of cells filled with abnormal intermediate filaments. The detected colocalization of neuronal and glial markers in balloon cells indicates a failure of cellular commitment during development. [source]

    Medium-term results of percutaneous vertebroplasty in multiple myeloma

    EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 1 2006
    Luis Ramos
    Abstract:, Vertebral compression fractures (VCFs) are common in multiple myeloma (MM). Percutaneous vertebroplasty (PVP) is used to stabilize vertebral collapse and treat the pain. Few studies have been carried out on PVP in MM and follow-up has tended to be short. We have prospectively evaluated the safety and efficacy of PVP in the VCFs resulting from MM or plasmacytomas. Nineteen PVP were performed in 12 consecutive patients. We monitored their pain and functional status using visual analog (VAS) and Eastern Cooperative Oncology Group (ECOG) scale, respectively. For a subjective assessment, every patient was asked about his/her degree of satisfaction. The mean age of the participants was 66 yr. Significant improvement occurred 1 d after PVP according to the VAS score (7.5 pre-PVP to 3.7, P < 0.0001) and ECOG assessment (3.1 to 2.5, P = 0.002). This significant improvement was maintained after 3.2 yr of follow-up. Sixty-three percent of patients were highly satisfied with the result of the PVP and 37% were satisfied. The peri-operative mortality was 0%. Leakage of the cement outside of the vertebral body was noted in 16 of 19 injected vertebrae (84%) but none of the patients developed any clinical or neurological symptoms. At the last follow-up, no further collapse in the treated or neighboring vertebrae was noted. VCFs caused by MM or plasmacytomas can be effectively treated by vertebroplasty. PVP is associated with early clinical improvement of pain and function and can be maintained after a long follow-up without major procedure-related complications. [source]

    Dystonia gravidarum: A new case with a long follow-up

    MOVEMENT DISORDERS, Issue 4 2007
    Alfonso Fasano MD
    Abstract We report a case of cervical dystonia occurring in a 33-year-old without personal history of movement disorder but with family history of essential tremor, primigravid, primiparous woman at 1 weeks' amenorrhea, resolved completely after delivery in the course of 3 months. Dystonia never recurred in the following 5 years. Several neurological disorders are known to occur or worsen during pregnancy. As far as we know, this is the second reported case of dystonia occurring during pregnancy, thus confirming that dystonia gravidarum represents a new entity and should be considered in women of reproductive age affected by dystonia, especially when presenting with rapid-onset cervical dystonia. © 2007 Movement Disorder Society [source]

    Glad SB, Aarseth JH, Nyland H, Riise T, Myhr K-M. Benign multiple sclerosis: a need for a consensus. Acta Neurol Scand: 2010: 122 (Suppl. 190): 44,50. © 2010 John Wiley & Sons A/S. Objectives,,, To investigate the impact of different definitions on the frequency of benign multiple sclerosis (MS) in patients with a long follow-up, and to study the presence of non-motor symptoms and employment across the definitions. Materials and methods,,, All patients alive (n = 188) with disease onset during 1976,1986 in Hordaland County, Norway, were clinically examined including the Expanded Disability Status Scale (EDSS) in 2003. Non-motor symptoms which included depression, cognitive impairment, fatigue and pain, and employment status were also registered. Three definitions of benign MS were used based on the following EDSS cut-off values: 2.0, 3.0 and 4.0. Two additional definitions were added using an EDSS ,4.0 and incorporating either full-time or full- and part-time employment status. Results,,, The frequency of benign MS increased from 14.5% for EDSS ,2.0 to 40.8% for EDSS ,4.0, but was only 12.3% for the definition based on full-time employment. Patients with an EDSS ,2.0 had markedly less non-motor symptoms and lower unemployment rates than the other groups. Conclusions,,, An EDSS score ,2.0 with at least 10 years of disease duration seems to be the most appropriate criterion in identifying patients with benign MS. [source]

    Risk of tumour seeding after percutaneous radiofrequency ablation for hepatocellular carcinoma

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 7 2005
    T. Livraghi
    Background: A recent small study reported a high rate of neoplastic seeding after cooled-tip radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) in patients who had undergone previous needle biopsy. Tumour seeding was associated with subcapsular tumour location, poorly differentiated tumours and a high ,-fetoprotein (AFP) level. The aim of the present study was to determine the rate of neoplastic seeding after RFA in a large series of unselected patients with HCC who had a long follow-up. Methods: A total of 1314 patients with 2542 nodules were treated in three centres. Median follow-up was 37 months. Needle biopsy had been performed before RFA in 241 patients (18·3 per cent). The influence of subcapsular location, high AFP level and previous biopsy on risk of tumour seeding was assessed. Results: Neoplastic seeding was identified in 12 patients (0·9 per cent); the rate was comparable at the three centres (0·9, 0·7 and 1·4 per cent). Only previous biopsy was significantly associated with tumour seeding (P = 0·004). Conclusion: RFA with a cooled-tip needle was associated with a low risk of neoplastic seeding, even in unselected patients. The use of biopsy before RFA is to be discouraged, particularly when liver transplantation is a possibility at a later date. Copyright © 2005 British Journal of Surgery Society Ltd.

    Prospective analysis of carotid artery flow in breast cancer patients treated with supraclavicular irradiation 8 or more years previously,

    CANCER, Issue 2 2008
    No increase in ipsilateral carotid stenosis after radiation noted
    Abstract BACKGROUND. To the authors' knowledge, the effects of supraclavicular fossa radiation on the carotid artery are not well described. In the current study, the authors performed a prospective study to examine the long-term risk of carotid artery stenosis after supraclavicular irradiation for breast cancer. METHODS. A total of 46 breast cancer patients who were treated with adjuvant radiation to the supraclavicular fossa with >8 years of follow-up underwent bilateral Doppler imaging of the carotid artery. Two independent cardiologists interpreted each ultrasound study with no knowledge of which side was treated. RESULTS. The median follow-up from the date of diagnosis was 14.6 years and the mean patient age at the time of ultrasound was 55 years. The median prescribed dose to the supraclavicular fossa was 50 grays. Four patients were found to have clinically relevant, asymptomatic carotid stenosis, for which a cardiology referral was necessary. Only 1 of these 4 patients had stenosis involving the irradiated carotid artery only; 1 patient had bilateral stenosis and 2 patients had only contralateral stenosis. There was no difference noted with regard to isolated ipsilateral versus contralateral medial intimal thickening of the carotid artery (5 patients vs 6 patients, respectively). Furthermore, there were no differences noted with regard to ipsilateral versus contralateral peak systolic flow in the internal (83.5 vs 85.6 cm/seconds; P = .522 by the Student t test and P = .871 by the signed rank test) or common (74.4 vs 77.0 cm/seconds; P = .462 by the Student t test and P = .246 by the signed rank test) carotid artery. CONCLUSIONS. In this prospective study of breast cancer patients with long follow-up, there was no evidence of late, clinically relevant stenosis, increased intimal thickening, or increased peak systolic carotid artery flow secondary to supraclavicular irradiation.

    MOOKP clinical results and Indications

    ACTA OPHTHALMOLOGICA, Issue 2009
    G FALCINELLI
    Purpose To demonstrate which are the reasons that permit by the modified osteo-odonto-keratoprosthesis (Mookp) technique to obtain in 275 blind eyes,with a basic pathology where 42% of eyes were dry,and 32% had severe physical/chemical burns,excellent anatomical and functional results. Methods Tables are shown which put into evidence the best visual acuity obtained in the 275 eyes affected by corneal blindness,operated by the Mookp technique from 1973 to 2008, with a 36 years causistry,with a very long follow-up. Results 275 blind eyes. Best Visual Acuity recovered, between 10/10 and 5/10 in 80.25% of operated eyes, excellent for any working activity,( best visual acuity recovered), between 10/10 and 2/10 in 91,20%, useful for any activity. Final V.A., between 10/10 and 5/10 in 67,68%, and between 10/10 and 2/10 in 78,11%- Conclusion The reasons for these excellent results are due to the biological properties of this Kpro invented by Strampelli and to the modifications made by Falcinelli. The indications for this technique are all those types of corneal blindness not treatable by penetrating keratoplasty. [source]
