RESUMEN

PURPOSE: To describe patient characteristics by disease stage, resectability status and current treatment management after first diagnosis of IIIB to IV1c advanced (AM)/metastatic melanoma (MM). METHODS/PATIENTS: Multicentre, retrospective study based on data from medical charts of patients > 18 years at MM first diagnosis, visited by oncologists at 4 reference centres in Spain: Hospital Universitario Gregorio Marañón (Madrid), Hospital General de Valencia (Valencia), Clínica Universidad de Navarra (Pamplona), and Hospital Clínic (Barcelona). RESULTS: Metastatic non-visceral melanoma (IIIB, IIIC, IV M1a) was reported in 139 (48.6%) patients and 40.9% (n = 117) were diagnosed with IV-M1c disease. 160 (55.9%) metastases were resectable. Available therapies under clinical practice were used in 210 patients; 74 were treated under clinical trials (CT). Intention-to-cure surgery (47.6%) was the most common treatment at time of MM diagnosis. Systemic (45.1% overall) therapy included chemo-, targeted- and immunotherapy (19.6%, 14.3%, 8.4%, respectively). At time of data collection, 26 patients were still alive and 120 had progressed to IV-M1c. Median overall survival (OS) was significantly larger in IIIB patients, 28.9 m (25.2-32.7); the shortest for IV-M1c patients, 11.0 m (8.7-13.3). CONCLUSIONS: Novel treatments are undoubtedly a major step forward in AM/MM, however these are often only available in the CT setting because early stages of development or country-specific regulations. Further prospective studies and multifactorial analysis should be performed to clearly identify possible clinical associations for outcome in Spanish patients with AM/MM.

RESUMEN

Introduction: Attention-deficit hyperactive disorder (ADHD) is the most common neurodevelopmental disorder in children. Diagnosis is currently based on behavioral criteria, but magnetic resonance imaging (MRI) of the brain is increasingly used in ADHD research. To date however, MRI studies have provided mixed results in ADHD patients, particularly with respect to the laterality of findings. Methods: We studied 849 children and adolescents (ages 6-21 y.o.) diagnosed with ADHD (n = 341) and age-matched typically developing (TD) controls with structural brain MRI. We calculated volumetric measures from 34 cortical and 14 non-cortical brain regions per hemisphere, and detailed shape morphometry of subcortical nuclei. Diffusion tensor imaging (DTI) data were collected for a subset of 104 subjects; from these, we calculated mean diffusivity and fractional anisotropy of white matter tracts. Group comparisons were made for within-hemisphere (right/left) and between hemisphere asymmetry indices (AI) for each measure. Results: DTI mean diffusivity AI group differences were significant in cingulum, inferior and superior longitudinal fasciculus, and cortico-spinal tracts (p < 0.001) with the effect of stimulant treatment tending to reduce these patterns of asymmetry differences. Gray matter volumes were more asymmetric in medication free ADHD individuals compared to TD in twelve cortical regions and two non-cortical volumes studied (p < 0.05). Morphometric analyses revealed that caudate, hippocampus, thalamus, and amygdala were more asymmetric (p < 0.0001) in ADHD individuals compared to TD, and that asymmetry differences were more significant than lateralized comparisons. Conclusions: Brain asymmetry measures allow each individual to serve as their own control, diminishing variability between individuals and when pooling data across sites. Asymmetry group differences were more significant than lateralized comparisons between ADHD and TD subjects across morphometric, volumetric, and DTI comparisons.

RESUMEN

INTRODUCTION: Despite the high degree of disability it entails, many patients with migraine have never visited their doctor for this reason. It is necessary to conduct a study to examine the characteristics of first-time visits as a step that must be carried out prior to establishing specific intervention measures for this group of patients. AIM: To determine the profile of the patients with migraine who visit a neurology service for the first time, together with the diagnostic and therapeutic attitudes that neurologists display towards them. PATIENTS AND METHODS: We conducted a cross-sectional, multi-centre study of neurology services across the country. The research included 168 neurologists who recruited 851 patients (74.6% females; mean age: 34.0 ± 10.7 years). Disability was assessed by means of the specific migraine questionnaire (Headache Impact Test) and the generic disability questionnaire (Sheehan Disability Scale). RESULTS: A third (66.5%) of the patients went for consultation following their doctor's advice, while the remaining 33.5% went on their own accord. Only 55.9% had been previously diagnosed with migraine. The main reasons for visiting were ineffective symptomatic treatment (25%) and an increase in the frequency or intensity of the attacks (23.4%). Although 70.3% of the patients had high disability scores on the Headache Impact Test, only 17.4% used specific treatment and only 13.3% were on preventive treatment. CONCLUSIONS: The PRIMERA study confirms, once again, that migraine is an under-diagnosed and under-treated condition in our setting, which means that specific educational interventions and training are still required for this pathology.

RESUMEN

INTRODUCTION: Migraine has recently been associated to certain personality profiles and styles of coping. AIM: To explore the association between personality factors, disability and the therapeutic management of migraine. PATIENTS AND METHODS: We conducted an epidemiological, cross-sectional, multi-centre study with patients with migraine visiting a neurology unit for the first time. Socio-demographic and clinical data were collected about the patients. The NEO-FFI (Neuroticism-Extraversion-Openness Five-Factor Inventory) was used to evaluate personality factors; the degree of disability was evaluated using the Headache Impact Test (HIT-6) and the number of lost workday equivalents (LWDE) was measured. Bivariate logistic regression analyses were also performed. RESULTS: A total of 736 patients were recruited, of whom 700 were suitable for inclusion in the analysis (75.6% females; mean age: 35.5 ± 11.5 years). In all, 68.9% presented migraine without aura, 1-4 seizures/month (66.7%) and of moderate intensity (58.1%). A total of 76.1% of patients had severe disability according to the HIT-6. Of the 554 active patients, the mean number of lost workday equivalents in the previous three months was 6.8 ± 8.2. Patients showed greater emotional instability than the general population and they scored lower on extraversion, openness, agreeableness and conscientiousness. All the patients were being treated for their migraine: 47.3% by means of stepped treatment between seizures; 39.9% intra-seizures, and stratified in only 12.9%. CONCLUSIONS: This study confirms the impact of migraine in terms of disability and in terms of loss of labour output, together with its association with personality factors.

RESUMEN

The peptide corresponding to the sequence (279-298) of the Hepatitis G virus (HGV/GBV-C) E2 protein was synthesized, and surface activity measurements, pi-A compression isotherms, and penetration of E2(279-298) into phospholipid monolayers spread at the air-water interface were carried out on water and phosphate buffer subphases. The results obtained indicated that the pure E2(279-298) Langmuir monolayer exhibited a looser packing on saline-buffered than on pure water subphase and suggest that the increase in subphase ionic strength stabilizes the peptide monolayer. To better understand the topography of the monolayer, Brewster angle microscopy (BAM) images of pure peptide monolayers were obtained. Penetration of the peptide into the pure lipid monolayers of dipalmitoylphosphatidylcholine (DPPC) and dimyristoylphosphatidylcholine (DMPC) and into mixtures of dimyristoylphosphatidylcholine/dimyristoylphosphatidylglycerol (DMPC/DMPG) at various initial surface pressures was investigated to determine the ability of these lipid monolayers to host the peptide. The higher penetration of peptide into phospholipids is attained when the monolayers are in the liquid expanded state, and the greater interaction is observed with DMPC. Furthermore, the penetration of the peptide dissolved in the subphase into these various lipid monolayers was investigated to understand the interactions between the peptide and the lipid at the air-water interface. The results obtained showed that the lipid acyl chain length is an important parameter to be taken into consideration in the study of peptide-lipid interactions.

RESUMEN

Resultados post operatorios de dos pacientes con diagnóstico de hiperplasia adrenal congénita por deficiencia de 21 hidroxilasa a quienes se les realizó genitoplastia feminizante. Se presentan 2 casos clínicos de pacientes con diagnóstico de hiperplasia adrenal congenital en el periodo neonatal a quienes se les realizó genitoplastia feminizante, utilizando la técnica de Fortunoff, modificada por Allen. De la primera paciente se muestran los resultados del post operatorio inmediato y a los 7 meses. De la segunda paciente mostramos igualmente los resultados del post operatorio inmediato, al año y en el inicio de la pubertad. Las dos pacientes muestran excelentes resultados cosméticos, que les han permitido un adecuado desarrollo. La genitoplastia feminizante debe ser realizada por cirujanos urólogos, especialmente entrenados en este tipo de patologías, para asegurar los mejores resultados estéticos y funcionales, ofreciéndole a la paciente un adecuado desarrollo físico y psicológico
