Levetiracetam and pregabalin for antiepileptic monotherapy in patients with primary brain tumors. A phase II randomized study.

BACKGROUND: In patients with brain tumors, the choice of antiepileptic medication is guided by tolerability and pharmacokinetic interactions. This study investigated the effectiveness of levetiracetam (LEV) and pregabalin (PGB), 2 non-enzyme-inducing agents, in this setting. METHODS: In this pragmatic, randomized, unblinded phase II trial (NCT00629889), patients with primary brain tumors and epilepsy were titrated to a monotherapy of LEV or PGB. Efficacy and tolerability were assessed using structured questionnaires. The primary composite endpoint was the need to discontinue the study drug, add-on of a further antiepileptic treatment, or occurrence of at least 2 seizures with impaired consciousness during 1 year follow-up. RESULTS: Over 40 months, 25 patients were randomized to LEV, and 27 to PGB. Most were middle-aged men, with a high-grade tumor and at least one generalized convulsion. Mean daily doses were 1125 mg (LEV) and 294 mg (PGB). Retention rates were 59% in the LEV group, and 41% in the PGB group. The composite endpoint was reached in 9 LEV and 12 PGB patients-need to discontinue: side effects, 6 LEV, 3 PGB; lack of efficacy, 1 and 2; impaired oral administration, 0 and 2; add-on of another agent: 1 LEV, 4 PGB; and seizures impairing consciousness: 1 in each. Seven LEV and 5 PGB subjects died of tumor progression. CONCLUSIONS: This study shows that LEV and PGB represent valuable monotherapy options in this setting, with very good antiepileptic efficacy and an acceptable tolerability profile, and provides important data for the design of a phase III trial.

Brain structure in movement disorders: a neuroimaging perspective.

Purpose of review: An overview of recent advances in structural neuroimaging and their impact on movement disorders research is presented. Recent findings: Novel developments in computational neuroanatomy and improvements in magnetic resonance image quality have brought further insight into the pathophysiology of movement disorders. Sophisticated automated techniques allow for sensitive and reliable in-vivo differentiation of phenotype/genotype related traits and their interaction even at presymptomatic stages of disease. Summary: Voxel-based morphometry consistently demonstrates well defined patterns of brain structure changes in movement disorders. Advanced stages of idiopathic Parkinson's disease are characterized by grey matter volume decreases in basal ganglia. Depending on the presence of cognitive impairment, volume changes are reported in widespread cortical and limbic areas. Atypical Parkinsonian syndromes still pose a challenge for accurate morphometry-based classification, especially in early stages of disease progression. Essential tremor has been mainly associated with thalamic and cerebellar changes. Studies on preclinical Huntington's disease show progressive loss of tissue in the caudate and cortical thinning related to distinct motor and cognitive phenotypes. Basal ganglia volume in primary dystonia reveals an interaction between genotype and phenotype such that brain structure changes are modulated by the presence of symptoms under the influence of genetic factors. Tics in Tourette's syndrome correlate with brain structure changes in limbic, motor and associative fronto-striato-parietal circuits. Computational neuroanatomy provides useful tools for in-vivo assessment of brain structure in movement disorders, allowing for accurate classification in early clinical stages as well as for monitoring therapy effects and/or disease progression.

Long-term outcome of primary endoresection of choroidal melanoma.

BACKGROUND: Endoresection of choroidal melanoma may offer the best hope of conserving vision in some patients but is controversial because of concerns regarding iatrogenic tumour dissemination. METHODS: Retrospective, non-randomised study of consecutive patients who underwent endoresection for choroidal melanoma at the Liverpool Ocular Oncology Centre between 1996 and 2010. RESULTS: The study included 71 patients with a mean age of 58.7 years. The tumour extended within 2 disc diameters of the optic disc in 46 (65%) eyes, involving the disc in 24 (34%) eyes. The mean largest basal tumour diameter and tumour thickness were 9.5 mm and 4.4 mm, respectively. The median follow-up was 4.1 years. The visual acuity at the latest follow-up was better than 6/30 in 31% eyes. The main causes of visual loss were foveal excision, rhegmatogenous retinal detachment (RD) and proliferative vitreo-retinopathy (PVR). Local recurrence developed in two patients (3%), who were treated by enucleation and proton beam radiotherapy, respectively. RD occurred in 16 cases (22%). Three (4%) eyes were enucleated, two because of PVR and one because of local tumour recurrence. Five patients died of metastatic disease. CONCLUSIONS: Endoresection achieved high rates of local tumour control. This operation would seem to be a useful alternative to radiotherapy as a means of conserving vision in eyes with juxtapapillary melanoma.

Primary mucosa-associated lymphoid tissue lymphoma of the salivary glands: a multicenter Rare Cancer Network study.

Purpose: Involvement of salivary glands with mucosa-associated lymphoid tissue (MALT) lymphoma is rare. This retrospective study was performed to assess the clinical profile, treatment outcome, and prognostic factors of MALT lymphoma of the salivary glands.Methods and Materials: Thirteen member centers of the Rare Cancer Network from 10 countries participated, providing data on 63 patients. The median age was 58 years; 47 patients were female and 16 were male. The parotid glands were involved in 49 cases, submandibular in 15, and minor glands in 3. Multiple glands were involved in 9 patients. Staging was as follows: IE in 34, IIE in 12, IIIE in 2, and IV in 15 patients.Results: Surgery (S) alone was performed in 9, radiotherapy (RI) alone in 8, and chemotherapy (CT) alone in 4 patients. Forty-one patients received combined modality treatment (S + RT in 23, S + CT in 8, RT + CT in 4, and all three modalities in 6 patients). No active treatment was given in one case. After initial treatment there was no tumor in 57 patients and residual tumor in 5. Tumor progression was observed in 23 (36.5%) (local in 1, other salivary glands in 10, lymph nodes in 11, and elsewhere in 6). Five patients died of disease progression and the other 5 of other causes. The 5-year disease-free survival, disease-specific survival, and overall survival were 54.4%, 93.2%, and 81.7%, respectively. Factors influencing disease-free survival were use of RI, stage, and residual tumor (p < 0.01). Factors influencing disease-specific survival were stage, recurrence, and residual tumor (p < 0.01).Conclusions: To our knowledge, this report represents the largest series of MALT lymphomas of the salivary glands published to date. This disease may involve all salivary glands either initially or subsequently in 30% of patients. Recurrences may occur in up to 35% of patients at 5 years; however, survival is not affected. Radiotherapy is the only treatment modality that improves disease-free survival. (C) 2012 Elsevier Inc.

Overuse of upper gastrointestinal endoscopy in a country with open-access endoscopy: a prospective study in primary care.

BACKGROUND: This prospective observational study was aimed at evaluating the appropriateness of use of upper gastrointestinal endoscopy (UGE) in primary care in a country with open access to and high availability of the procedure. METHODS: Outpatients were consecutively included in two clinical settings: Setting A (20 primary care physicians during 4 weeks) and B (university-based outpatient clinic during 3 weeks). In patients undergoing UGE, appropriateness of referral was judged by explicit Swiss criteria developed by the RAND/UCLA panel method. RESULTS: Patient visits (8135) were assessed. Six hundred eleven patients complained of upper gastrointestinal symptoms. Physicians decided to perform UGE in 63 of these patients. Twenty-five (40%) of the endoscopies were rated appropriate, 7 (11%) equivocal, and 31 (49%) inappropriate. Overuse of UGE occurred in 5.1% (setting A: 4.7%; setting B:6.5%; p = 0.39) of the patients who presented with upper gastrointestinal symptoms. The decision to perform UGE in previously untreated dyspeptic patients was the most common clinical situation resulting in overuse. CONCLUSIONS: Inappropriate use of UGE is high in Switzerland. However, to better reflect primary care decision making, overuse should be related not only to patients referred for a medical test, but also to the number of patients who complain of the symptoms that would be investigated by the procedure.

Prediction of 18-month survival in patients with primary myelodysplastic syndrome. A regression model and scoring system based on the combination of chromosome findings and the Bournemouth score.

The predictive potential of six selected factors was assessed in 72 patients with primary myelodysplastic syndrome using univariate and multivariate logistic regression analysis of survival at 18 months. Factors were age (above median of 69 years), dysplastic features in the three myeloid bone marrow cell lineages, presence of chromosome defects, all metaphases abnormal, double or complex chromosome defects (C23), and a Bournemouth score of 2, 3, or 4 (B234). In the multivariate approach, B234 and C23 proved to be significantly associated with a reduction in the survival probability. The similarity of the regression coefficients associated with these two factors means that they have about the same weight. Consequently, the model was simplified by counting the number of factors (0, 1, or 2) present in each patient, thus generating a scoring system called the Lausanne-Bournemouth score (LB score). The LB score combines the well-recognized and easy-to-use Bournemouth score (B score) with the chromosome defect complexity, C23 constituting an additional indicator of patient outcome. The predicted risk of death within 18 months calculated from the model is as follows: 7.1% (confidence interval: 1.7-24.8) for patients with an LB score of 0, 60.1% (44.7-73.8) for an LB score of 1, and 96.8% (84.5-99.4) for an LB score of 2. The scoring system presented here has several interesting features. The LB score may improve the predictive value of the B score, as it is able to recognize two prognostic groups in the intermediate risk category of patients with B scores of 2 or 3. It has also the ability to identify two distinct prognostic subclasses among RAEB and possibly CMML patients. In addition to its above-described usefulness in the prognostic evaluation, the LB score may bring new insights into the understanding of evolution patterns in MDS. We used the combination of the B score and chromosome complexity to define four classes which may be considered four possible states of myelodysplasia and which describe two distinct evolutional pathways.

Treatment strategies in primary vitreoretinal lymphoma: a 17-center European collaborative study.

IMPORTANCE: The best treatment option for primary vitreoretinal lymphoma (PVRL) without signs of central nervous system lymphoma (CNSL) involvement determined on magnetic resonance imaging or in cerebrospinal fluid is unknown. OBJECTIVE: To evaluate the outcomes of treatment regimens used for PVRL in the prevention of subsequent CNSL. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study was conducted at 17 referral ophthalmologic centers in Europe. We reviewed clinical, laboratory, and imaging data on 78 patients with PVRL who did not have CNSL on presentation between January 1, 1991, and December 31, 2012, with a focus on the incidence of CNS manifestations during the follow-up period. INTERVENTIONS: The term extensive treatment was used for various combinations of systemic and intrathecal chemotherapy, whole-brain radiotherapy, and peripheral blood stem cell transplantation. Therapy to prevent CNSL included ocular radiotherapy and/or ocular chemotherapy (group A, 31 patients), extensive systemic treatment (group B, 21 patients), and a combination of ocular and extensive treatment (group C, 23 patients); 3 patients did not receive treatment. A total of 40 patients received systemic chemotherapy. MAIN OUTCOMES AND MEASURES: Development of CNSL following the diagnosis of PVRL relative to the use or nonuse of systemic chemotherapy and other treatment regimens. RESULTS: Overall, CNSL developed in 28 of 78 patients (36%) at a median follow-up of 49 months. Specifically, CNSL developed in 10 of 31 (32%) in group A, 9 of 21 (43%) in group B, and 9 of 23 (39%) in group C. The 5-year cumulative survival rate was lower in patients with CNSL (35% [95% CI, 50% to 86%]) than in patients without CNSL (68% [95% CI, 19% to 51%]; P = .003) and was similar among all treatment groups (P = .10). Adverse systemic effects occurred in 9 of 40 (23%) patients receiving systemic chemotherapy; the most common of these effects was acute renal failure. CONCLUSIONS AND RELEVANCE: In the present series of patients with isolated PVRL, the use of systemic chemotherapy was not proven to prevent CNSL and was associated with more severe adverse effects compared with local treatment.

Vers un accès à des soins de qualité pour les personnes lesbiennes, gays, bisexuelles et transgenres. [Access to quality primary care for LGBT people].

Cet article propose une approche globale de la santé des personnes lesbiennes, gays, bisexuelles, et transgenres (LGBT), où respect des singularités et non-jugement occupent une position centrale. Il invite à dépasser une vision centrée sur les risques liés au VIH. Pour qui n'a pas connu de questionnement en lien avec son orientation sexuelle ou son identité de genre, il est difficile de concevoir comment la découverte d'une caractéristique identitaire pendant l'enfance peut se transformer sous le regard des autres en un fardeau souvent invisible mais fréquemment associé avec une morbidité émotionnelle et médicale considérable. Cet article pose la question suivante : combien de personnes LGBT ressortent chaque semaine d'une consultation médicale sans avoir eu l'opportunité de bénéficier d'une écoute, d'un soutien et de soins adaptés ? [Abstract] This article offers a comprehensive approach to the health of lesbian, gay, bisexual and transgender (LGBT) people, where respect for diversity and non judgemental care play a central role. It calls for a health and medical vision that goes beyond HIV risk. For those who never had to question their own sexual orientation or gender identity, it is certainly difficult to understand how the discovery of one's identity trait in childhood or early adolescence can be transformed under social pressure into a burden which often remains invisible but is associated with considerable emotional and medical morbidity. This article raises the following question : How many LGBT patients go unnoticed every week, leaving the physician's office without an opportunity to receive appropriate listening, support and care ?

Transduction of CpG DNA-stimulated primary human B cells with bicistronic lentivectors.

Recently, using HIV-1-derived lentivectors, we obtained efficient transduction of primary human B lymphocytes cocultured with murine EL-4 B5 thymoma cells, but not of isolated B cells activated by CD40 ligation. Coculture with a cell line is problematic for gene therapy applications or study of gene functions. We have now found that transduction of B cells in a system using CpG DNA was comparable to that in the EL-4 B5 system. A monocistronic vector with a CMV promoter gave 32 +/- 4.7% green fluorescent protein (GFP)+ cells. A bicistronic vector, encoding IL-4 and GFP in the first and second cistrons, respectively, gave 14.2 +/- 2.1% GFP+ cells and IL-4 secretion of 1.3 +/- 0.2 ng/10(5) B cells/24 h. This was similar to results obtained in CD34+ cells using the elongation factor-1alpha promoter. Activated memory and naive B cells were transducible. After transduction with a bicistronic vector encoding a viral FLIP molecule, vFLIP was detectable by FACS or Western blot in GFP+, but not in GFP-, B cells, and 57% of sorted GFP+ B cells were protected against Fas ligand-induced cell death. This system should be useful for gene function research in primary B cells and development of gene therapies.

Médecine interne générale ambulatoire: quelques enseignements de la littérature en 2005 [Primary care in general internal medicine: relevant information in 2005]

During the year 2005, the chief residents of the University Medical Outpatient Clinic of Lausanne have done a database of useful articles for daily practice, scientifically validated and with excellent didactic quality, from 10 electronic journals. They have used those selected articles in personal meetings between the chief residents on a regular basis and the possibility to access the database by the junior physicians. Six of these articles concerning different topics (depression, tuberculosis detection, anticoagulation at home, cholinesterase inhibitors, insomnia and therapies, transdermal nitroglycerin and tendinopathies) are presented.

Anti-idiotypic monoclonal antibody AB3, reacting with the primary antigen (CEA), can localize in human colon-carcinoma xenografts as efficiently as AB1.

BALB/c mice were immunized with anti-idiotypic monoclonal (MAb) antibody (anti-Id or Ab2) directed against an AB1 MAb anti-carcinoembryonic (CEA) in order to obtain AB3 MAbs (anti-anti-Id). AB3 MAbs were shown to recognise the primary antigen (CEA) and one of them was tested extensively in vitro and in vivo. This AB3 MAb was shown to bind specifically to CEA on frozen sections of a human colon carcinoma by immunoperoxidase. Scatchard plot analyses showed that the affinity of this AB3 was of the same order of magnitude as the AB1. In vivo experiments, in nude mice bearing CEA-producing human colon-carcinoma xenografts showed that up to 30% of the intravenously injected dose of 125I-labelled AB3 were localized per gram of tumour tissue. Furthermore, calculation of the ratios of AB3 concentration in the tumour over those in normal organs such as lung, liver, kidney, spleen and bone gave relatively high values similar to results obtained with AB1. All together our results show that AB3 can localize as efficiently and specifically in the tumour as AB1, despite the fact that the mice from which it was derived were immunized with a mouse MAb (AB2) and had never been exposed to CEA.
