The H-ATOMIC Criteria for the Etiologic Classification of Patients with Intracerebral Hemorrhage
Background and Purpose
There are no generally accepted criteria for the etiologic classification of intracerebral hemorrhage
(ICH). For this reason, we have developed a set of etiologic criteria and have
applied them to a large number of patients to determine their utility.
Methods
The H-ATOMIC classification includes 7 etiologic categories: Hypertension, cerebral Amyloid
angiopathy, Tumour, Oral anticoagulants, vascular Malformation, Infrequent causes
and Cryptogenic. For each category, the etiology is scored with three degrees of certainty:
Possible(3), Probable(2) and Definite(1). Our aim was to perform a basic study consisting of
neuroimaging, blood tests, and CT-angio when a numerical score (SICH) suggested an
underlying structural abnormality. Combinations of >1 etiologic category for an individual
patient were acceptable. The criteria were evaluated in a multicenter and prospective study
of consecutive patients with spontaneous ICH.
Results
Our study included 439 patients (age 70.8 ± 14.5 years; 61.3% were men). A definite etiology
was achieved in 176 (40.1% of the patients: Hypertension 28.2%, cerebral Amyloid
angiopathy 0.2%, Tumour 0.2%, Oral anticoagulants 2.2%, vascular Malformation 4.5%,
Infrequent causes 4.5%). A total of 7 patients (1.6%) were cryptogenic. In the remaining
58.3% of the patients, ICH was attributable to a single (n = 56, 12.7%) or the combination of
2 (n = 200, 45.5%) possible/probable etiologies. The most frequent combinations of etiologies
involved possible hypertension with possible CAA (H3A3, n = 38) or with probable CAA
(H3A2, n = 29), and probable hypertension with probable OA (H2O2, n = 27). The most frequent category with any degree of certainty was hypertension (H1+2+3 = 80.6%) followed
by cerebral amyloid angiopathy (A1+2+3 = 30.9%).
Conclusions
According to our etiologic criteria, only about 40% patients received a definite diagnosis,
while in the remaining patients ICH was attributable to a single possible/probable etiology or
to more than one possible/probable etiology. The use of these criteria would likely help in
the management of patients with ICH.This work was supported by Ministery of Health-Instituto de Salud Carlos III: RETICS (Redes temáticas de Investigación Cooperativa) INVICTUS RD012/0014 (JM-F, PC-R, AM-D, LP-S, RD-M), FEDER (Fondo Europeo de Desarrollo Regional)

Efficacy of radial extracorporeal shock wave therapy compared with botulinum toxin type A injection in treatment of lower extremity spasticity in subjects with cerebral palsy: A randomized, controlled, cross-over study
Objectives: To investigate whether botulinum toxin type A (BTX-A) injection is more effective than radial extracorporeal shock wave therapy in reducing plantar flexor muscle spasticity in subjects with cerebral palsy.
Methods: A total of 68 subjects with cerebral palsy were randomly allocated to BTX-A injection (Group 1) or radial extracorporeal shock wave therapy (Group 2) (first experiment; E1). Outcome was evaluated using the Tardieu V1 and V3 stretches, at 3 weeks, 2 months (M2) and M3 after baseline. At M6 subjects in Group 1 received radial extracorporeal shock wave therapy and subjects in Group 2 received BTX-A injection (second experiment; E2); outcome was evaluated as in E1. Treatment success was defined as improvement in foot dorsiflexion ≥10° when performing the V3 stretch at M2 in both experiments.
Results: In both experiments mean V1 and V3 significantly improved over time. In E1 both treatments resulted in similar treatment success. In E2 fewer subjects treated with BTX-A injection reached the criteria of treatment success than did subjects treated with radial extracorporeal shock wave therapy, which was due to a carry-over effect from E1. No significant complications were observed.
Conclusion: BTX-A injection is not superior to radial extracorporeal shock wave therapy in the treatment of plantar flexor muscle spasticity in subjects with cerebral palsy
Enterprise internships: modern fashion or real need?
The objectives of this work are twofold. First, it aims to reflect on student internship placements as a tool for developing the engineering curriculum. Secondly, we present a webbased software for the efficient management of enterprise internships. This tool is scalable, allowing the management of an increased number of students while minimizing the requirement for managing tim
La Inserció universitaria dels alumnes de primer curs
Partint de que els alumnes que arriben a l'EPS ja han assolit la decisió prèvia de seguir estudis tècnics, i després del primer semestre d'haver iniciat els seus estudis, els proposem una reflexió sobre els seus estudis i la possibilitat d'exposar les seves il·lusions i desencisaments respecte al que n'esperaven de la universitat. Aprofitem per a remarca-els-hi la disponibilitat dels processos que ha organitzat el Centre per a facilitar-els-hi la seva integració als estudis. Aquesta part del procés s'inicia amb l'oportunitat de respondre una enquesta preparada per a fer el seguiment de la seva inserció universitària amb preguntes de resposta oberta que al mateix temps d'ajudar a la verificació del funcionament de les diferents activitats de suport que els dóna l'escola, serveixen de invitació a la reflexió tant per als alumnes matriculats per primera vegada com per als professors i equip de direcció de l'Escola Politècnica Superior de la Universitat de Girona a qui es fan arribar els resultats de les valoracions de l'enquest

Brain metabolic pattern analysis using a magnetic resonance spectra classification software in experimental stroke
Ajuts: EU FEDER funds Redes Temáticas de Investigación Cooperativa Sanitaria RETICS-INVICTUS-RD12/014/0002Magnetic resonance spectroscopy (MRS) provides non-invasive information about the metabolic pattern of the brain parenchyma in vivo. The SpectraClassifier software performs MRS pattern-recognition by determining the spectral features (metabolites) which can be used objectively to classify spectra. Our aim was to develop an Infarct Evolution Classifier and a Brain Regions Classifier in a rat model of focal ischemic stroke using SpectraClassifier. A total of 164 single-voxel proton spectra obtained with a 7 Tesla magnet at an echo time of 12 ms from non-infarcted parenchyma, subventricular zones and infarcted parenchyma were analyzed with SpectraClassifier (). The spectra corresponded to Sprague-Dawley rats (healthy rats, n = 7) and stroke rats at day 1 post-stroke (acute phase, n = 6 rats) and at days 7 ± 1 post-stroke (subacute phase, n = 14). In the Infarct Evolution Classifier, spectral features contributed by lactate + mobile lipids (1.33 ppm), total creatine (3.05 ppm) and mobile lipids (0.85 ppm) distinguished among non-infarcted parenchyma (100% sensitivity and 100% specificity), acute phase of infarct (100% sensitivity and 95% specificity) and subacute phase of infarct (78% sensitivity and 100% specificity). In the Brain Regions Classifier, spectral features contributed by myoinositol (3.62 ppm) and total creatine (3.04/3.05 ppm) distinguished among infarcted parenchyma (100% sensitivity and 98% specificity), non-infarcted parenchyma (84% sensitivity and 84% specificity) and subventricular zones (76% sensitivity and 93% specificity). SpectraClassifier identified candidate biomarkers for infarct evolution (mobile lipids accumulation) and different brain regions (myoinositol content).
