Abstract
Non-biodegradable metals such as mercury accumulate in living organisms during
life (bioaccumulation) and also within trophic webs (biomagnification) and may
reach high concentrations in humans. The contamination of humans by mercury in
drinking water and food may be common, in particular in riverside communities
that have a diet rich in fish. In vitro studies of human cell
lines exposed to the cytotoxic and mutagenic effects of methylmercury have shown
that prolactin has potential cytoprotective properties and may act as a
co-mitogenic factor and inhibitor of apoptosis. The present in
vivo study investigated the protective potential of prolactin
against the toxic effects of methylmercury in the mammal Mus
musculus. Histological and biochemical analyses, together with
biomarker of genotoxicity, were used to verify the protective potential of
prolactin in mice exposed to methylmercury. The reduction in kidney and liver
tissue damage was not significant. However, results of biochemical and genotoxic
analyses were excellent. After prolactin treatment, a significant reduction was
observed in biochemical parameters and mutagenic effects of methylmercury. The
study results therefore indicated that prolactin has protective effects against
the toxicity of methylmercury and allowed us to suggest the continuation of
research to propose prolactin in the future, as an alternative to prevent the
damage caused by mercury, especially in populations that are more exposed.

Abstract
Summary Objectives. To describe the prevalence of allergic sensitization to Storage Dust Mites (SDM), access whether the place of living and occupational exposure were determinants for SDM sensitization and study association between Lepidoglyphus destructor and other SDM sensitization. Methods. Prospective analysis of patients evaluated for suspected allergic rhinitis and/or asthma that performed Skin Prick Tests (SPT) to SDM between January and December 2018 in our Department. Results. Two hundred consecutive patients were evaluated for rhinitis and/or asthma in our outpatient consultation: 123 (61.5%) presented positivity for at least one SDM, 68.3% were female and the mean age was 33.1 ± 12.12. Lepidoglyphus destructor (69.9%) was the most prevalent, followed by Tyrophagus putrescentiae (50.4%), Blomia tropicalis and Glycyphagus domesticus (48.8%) and Acarus siro (24.4%). Living in a rural place was not associated with a higher prevalence of sensitization to SDM, except for Acarus siro (p = 0.032), and working in a place with storage areas was not associated with sensitization to any of SDM. Sensitization to Lepidoflyphus destructor was associated with sensitization to Blomia tropicalis, Glycyphagus domesticus and Tyrophagus putrescentiae (p less than 0.005), but not with Acarus siro. Conclusions. Our study suggests that our population, independently of their occupational exposure and place of residency, are sensitized to SDM and that evaluation of sensitization to SDM should be considered as standard practice.

Abstract
OBJECTIVE To analyze component resolved diagnosis to Dermatophagoides pteronyssinus (Der p) in patients with respiratory allergy and its relationship with clinical severity in different geographical areas. METHODS 217 patients (mean age 25.85±12.7 years; 51.16% females) were included, selected from 13 centers in Portugal (5 from North, n=65). All had allergic rhinitis, with or without asthma, and had positive skin prick tests to at least one dust mite. Specific IgE (sIgE) to Der p, Dermatophagoides farinae, Lepidoglyphus destructor, Der p1, Der p 2, Der p 10 and Der p 23 were determined by ImmunoCAP. Statistical analysis (Mann Whitney U test) compared patients with rhinitis vs rhinitis and asthma; mild vsmoderate-to-severe rhinitis; North vs South. RESULTS Prevalence of sensitization was 98.2% to Der p, and 72.4%, 89.4%, 9.7% and 77% to Der p 1, Der p 2, Der p 10 and Der p 23, respectively. Corresponding median sIgE levelswere 8.56, 17.7, 0.01 and 3.95 kUA/L. sIgE to all allergens was higher in patients with moderate-to-severe rhinitis and rhinitis with asthma but not statistically significant (NSS). sIgE to Der p 2 was significantly higher in the South when compared with the North (p=0.0496). CONCLUSIONS sensitization to Der p is the most common in Portugal. Der p 2 had the highest prevalence and median sIgE levels. All sIgE to molecular components were higher in more symptomatic patients (NSS). sIgE to Der p 2 was higher in the South, which may be related to the warmer temperature and/or the larger sample size.

Abstract
This paper provides additional negative data regarding the paper Evaluation of thermal properties of thin films by IR radiometry using a comprehensive set of Zr–O–N thin films [1]. In that paper, a matrix of samples was prepared to evaluate the so-called Extremum method for the analysis of Infrared (IR) radiometry data. Such matrix was composed by 3 types of films with 4 different thickness in 3 types of substrates, totalizing 36 samples in total. The data of this paper can be divided into three separate categories: i) lack of adhesion of the films deposited on Teflon, simultaneously to the films deposited on other substrates. ii) Improvement of the signal and signal-to-noise ratio on samples that did not present an extremum (minimum or maximum) using the initial (more conventional) way of measurement. iii) It is also presented a failed fitting of the IR radiometry data created with entangled material parameters. All this data is relevant for researchers devoted to measurement of thermal properties of thin films by IR radiometry that employ the two layer model and Extremum Method.

Abstract
The aim of this work was to assess the occupational dose received by an interventional radiologist (IR) during computed tomography fluoroscopy (CTF)-guided procedures; to identify the most exposed areas of the body including the hands and fingers; to suggest recommendations for individual monitoring; and to improve radiation safety of the practice. A total of 53 CTF-guided procedures were studied. Twelve whole-body dosimeters were worn by the IR in each procedure for the assessment of the personal dose equivalent, Hp(10), on the chest, waist, and back, both over and under the lead apron, as well as the personal dose equivalent, Hp(0.07), on both arms, knees, and feet. Special gloves with casings to fit extremity dosimeters were prepared to assess Hp(0.07) to the fingers. The measured chest dose values were higher than those on the waist and back; the dominant hand or the left side was the most exposed. In general, the ring, middle, and index fingers of the dominant hand were the most exposed (maximum in the 36-39 mSv range), while wrist dose was negligible compared to finger doses. Based on the results obtained the following recommendations are suggested: protective devices (lead aprons, thyroid shield, and goggles) should be worn; Hp(10) should be assessed at the chest level both above and below the lead apron; finger doses can be measured on the basis of each middle finger; the arm closer to the beam should be monitored; and finally, a wrist dosimeter will not provide useful information.

Abstract
Os objetivos do estudo foram avaliar a resistência à fratura (RF) após fadiga e a resistência de união ao push-out (RU) com e sem fadiga, em retentores intrarradiculares personalizados fabricados com diferentes materiais estéticos em CAD/CAM. Noventa dentes foram selecionados, preparados endodonticamente e submetidos ao preparo do espaço intraradicular. Os dentes foram distribuídos aleatoriamente em 3 grupos de acordo com o material do retentor: fibra de vidro experimental (FV) cerâmica híbrida Vita Enamic (CH) e resina composta nano cerâmica Lava Ultimate (RC). Os restentores foram fabricados em CAD/CAM e cimentados com cimento resinoso autoadesivo (Rely X U200). Um subgrupo de 30 espécimes (n10) foi submetido a fadiga (1.000.000 ciclos a 5 Hz) e, em seguida, ao ensaio de RF. Outro subgrupo com 60 espécimes foi submetido ao ensaio de RU, com e sem fadiga. Os dados foram submetidos à análise de variância (RF - ANOVA 1 fator RU - ANOVA 2 fatores) e teste de Tukey (a0,05). As médias de RF (N±DP) para os materiais foram 407,61±109,04 (FV), 414.52±83.95 (CH), and 621,38±100,35 (RC), com RC apresentando valores de RF significativamente superiores (p<0,05). Para RU, não houve diferença estatisticamente significante entre os materiais, com e sem fadiga (p>0,05). Pode-se concluir que o tipo de material utilizado para confecção do retentor personalizado influenciou significativamente na RF, mas não na RU dos espécimes. A realização da fadiga não influenciou na RU para os diferentes materiais.Palavras-chave: CAD-CAM. Pino Intrarradicular. Materiais Dentários.

Abstract
Summary Allergies to red meat associated with galactose-α-1,3-galactose, commonly known as α-gal, are rare and have only recently been described. At this time, the literature reports only one case documented in Portugal. In this study, we report the case of a 76-year-old male with an immediate reaction following the ingestion of red meat. Rigorous diagnostic exams, including prick test, prick-to-prick tests, serum specific IgE and SDS-PAGE IgE-immunoblotting, were performed. The α-gal epitope IgE re-turned a value of 35.3 kUA/L, leading the authors to believe that this is an atypical case of α-gal allergy.

Abstract
Multiple Sclerosis (MS) treatment with natalizumab is associated with Progressive Multifocal Leukoencephalopathy (PML). The risk of PML being related to the anti-JCV antibody index is well established, but there is less known about seroconversion rates in natalizumab-treated patients and longitudinal variation in the anti-JCV antibody index. Our objective was to assess anti-JCV antibody prevalence in an MS population and to evaluate the evolution of the anti-JCV antibody index in natalizumab-treated patients. To assess anti-JCV antibody prevalence, we included all patients who had the anti-JCV antibody test in our consultation, regardless of the treatment. To evaluate the evolution of the anti-JCV antibody index and seroconversion, only natalizumab-treated patients with at least two samples were selected. Demographic characteristics were evaluated. From a total of 371 patients included, 68.19% (n=253) were seropositive for anti-JCV antibodies (JCV+). There was a significant difference in anti-JCV antibody seropositivity concerning gender (male 76.27% vs. female 64.43%, p=0.023), but not age. To evaluate seroconversion, 85 patients who were initially seronegative (JCV-) were selected. The annual rate of seroconversion in the first two years was stable, but after that there was a significant increase with treatment duration (ρ=0.90, p=0.037): in the first year it was 5.88% (n=5/85); in the second, 5.71% (n=4/70); in the third, 6.82% (n=3/44); in the fourth, 10.34% (n=3/29); and in the fifth, 15.0% (n=3/20). The mean index variability was higher in patients who experienced seroconversion (1.16±0.97), followed by JCV+ patients (0.44±0.48), compared to JCV- patients (0.08±0.05). In conclusion, anti-JCV antibody prevalence in our population is comparable to other reported cohorts. The seroconversion rate increased with treatment duration. We found a high fluctuation in the antibody index in JCV+ patients.

Abstract
This study investigated to what extent a single exposure to low doses of ionizing radiation can induce genotoxic damage in irradiated adult zebrafish (Danio rerio) and its non-irradiated F1 progeny. Four groups of adult zebrafish were irradiated with a single dose of X-rays at 0 (control), 100, 500 and 1000 mGy, respectively, and couples of each group were allowed to reproduce following irradiation. Blood of parental fish and whole-body offspring were analysed by the comet assay for detection of DNA damage. The level of DNA damage in irradiated parental fish increased in a radiation dose-dependent manner at day 1 post-irradiation, but returned to the control level thereafter. The level of DNA damage in the progeny was directly correlated with the parental irradiation dose. Results highlight the genotoxic risk of a single exposure to low-dose ionizing radiation in irradiated individuals and also in its non-irradiated progeny.

Abstract
Background and Purpose—
Atrial fibrillation (AF) is increasingly recognized as the single most important cause of disabling ischemic stroke in the elderly. We undertook an international survey to characterize the frequency of AF-associated stroke, methods of AF detection, and patient features.
Methods—
Consecutive patients hospitalized for ischemic stroke in 2013 to 2014 were surveyed from 19 stroke research centers in 19 different countries. Data were analyzed by global regions and World Bank income levels.
Results—
Of 2144 patients with ischemic stroke, 590 (28%; 95% confidence interval, 25.6–29.5) had AF-associated stroke, with highest frequencies in North America (35%) and Europe (33%) and lowest in Latin America (17%). Most had a history of AF before stroke (15%) or newly detected AF on electrocardiography (10%); only 2% of patients with ischemic stroke had unsuspected AF detected by poststroke cardiac rhythm monitoring. The mean age and 30-day mortality rate of patients with AF-associated stroke (75 years; SD, 11.5 years; 10%; 95% confidence interval, 7.6–12.6, respectively) were substantially higher than those of patients without AF (64 years; SD, 15.58 years; 4%; 95% confidence interval, 3.3–5.4;
P
<0.001 for both comparisons). There was a strong positive correlation between the mean age and the frequency of AF (
r
=0.76;
P
=0.0002).
Conclusions—
This cross-sectional global sample of patients with recent ischemic stroke shows a substantial frequency of AF-associated stroke throughout the world in proportion to the mean age of the stroke population. Most AF is identified by history or electrocardiography; the yield of conventional short-duration cardiac rhythm monitoring is relatively low. Patients with AF-associated stroke were typically elderly (>75 years old) and more often women.

Abstract
The analysis of outcomes from patients with severe asthma treated with omalizumab, using real-life prospective data, should contribute to future informed decisions about this treatment in Portugal. The aim of this study was to assess the clinical effect of omalizumab in Portuguese patients with severe persistent allergic asthma, considering specifically asthma control and exacerbations. This was an observational, prospective, multicentre study. Data were collected at routine care over a 12-month period. Disease control was defined by Control of Allergic Rhinitis and Asthma Test (CARAT) global score >24. All asthma patients already under treatment with omalizumab in 7 departments from 6 Portuguese hospitals were included (n=48). Most (77%) patients were female and the mean (SD) age was 51.9 (10.2) years old. During the study period, asthma was controlled in 34% of the visits and the 12-month exacerbation rate was 1.7 per patient (0.6 with unscheduled medical care). One-third of the patients needed unscheduled medical care because of asthma and 29% had to start or increase oral corticosteroid. There was still a 41% reduction in the total sum of oral corticosteroids usage from the first to the last trimester of the study. During routine treatment with omalizumab, Portuguese patients with severe asthma achieved asthma control in 1/3 of the visits and only 1/3 needed unscheduled or Emergency Room care because of asthma exacerbations. These outcomes support the maintenance of the clinical effect during treatment with omalizumab in routine care in Portugal.

Abstract
INTRODUCTION The accurate identification of sensitizing proteins in patients allergic to plant-derived foods is extremely important, allowing a correct dietary advice. We aimed to evaluate the diagnostic usefulness of skin prick tests (SPT) and specific IgE (sIgE) with single molecular allergen components in children with allergy to fruits and vegetables. METHODS Twenty children underwent SPT with a palm profilin (Pho d 2, 50 μg/mL); a Mal d 1-enriched apple extract (2 μg/mL) (PR-10 allergen); and a peach Lipid Transfer Protein (LTP) (Pru p 3, 30 μg/mL). Detection of sIgE to rBet v 1, rBet v 2, Phl p 12 and Pru p 3 was also measured. RESULTS Allergy to multiple fruits and vegetables was observed in 11 (55%) children. Sensitization by SPT to Pho d 2, Mal d 1, and Pru p 3 occurred in 5, 7, and 8 cases, respectively. LTP sensitization appeared to be associated with peach allergy but not with severe reactions, and profilins sensitization to melon and tomato allergy. Kiwi sensitization (12 cases), the plant-derived food that caused more allergic reactions, seemed mostly species-specific. The concordance of SPT extracts and sIgE to the corresponding pan-allergens was high for profilins (k=0.857) and LTP (k=0.706), while for PR-10 allergens it was absent (k=0.079). CONCLUSIONS Pan-allergen sensitization in children with allergy to fruits and vegetables was common and often multiple. There was no association of severe reactions to LTP sensitization. The introduction of routine SPT to pan-allergens can be a simple and feasible way of improving diagnostic and therapeutic efficacy.

Abstract
BACKGROUND Severe combined immunodeficiency (SCID) is one of the most severe forms of primary immunodeficiency. The objectives of this study were to analyze the diagnosis, treatment, and prognosis of SCID in Brazil and to document the impact of BCG vaccine. METHODS We actively searched for cases by contacting all Brazilian referral centers. RESULTS We contacted 23 centers and 70 patients from 65 families. Patients were born between 1996 and 2011, and 49 (70%) were male. More than half (39) of the diagnoses were made after 2006. Mean age at diagnosis declined from 9.7 to 6.1 months (P = .058) before and after 2000, respectively, and mean delay in diagnosis decreased from 7.9 to 4.2 months (P = .009). Most patients (60/70) were vaccinated with BCG before the diagnosis, 39 of 60 (65%) had complications related to BCG vaccine, and the complication was disseminated in 29 of 39 (74.3%). Less than half of the patients (30, 42.9%) underwent hematopoietic stem cell transplantation (HSCT). Half of the patients died (35, 50%), and 23 of these patients had not undergone HSCT. Disseminated BCG was the cause of death, either alone or in association with other causes, in 9 of 31 cases (29%, no data for 4 cases). CONCLUSIONS In Brazil, diagnosis of SCID has improved over the last decade, both in terms of the number of cases and age at diagnosis, although a much higher number of cases had been expected. Mortality is higher than in developed countries. Complications of BCG vaccine are an important warning sign for the presence of SCID and account for significant morbidity during disease progression.

Abstract
BACKGROUND Anaphylaxis is an acute multisystemic and potentially fatal reaction, resulting from the rapid release of inflammatory mediators. Its exact prevalence is unknown. In children, foods are the most significant triggers for IgE-mediated anaphylaxis. OBJECTIVES To characterise the cases of anaphylaxis evaluated in an Allergy Division of a Central Paediatric Hospital. MATERIAL AND METHODS A review of all cases of anaphylaxis evaluated from 2001 to 2009. Anaphylaxis was defined according to Sampson's 2006 criteria. RESULTS Seventy-three children had anaphylactic reactions (47 male), of which 64% had history of atopy. Age at time of reaction ranged between 17 days and 15 years old (median: four years). Food was the most frequently identified cause (n=57), followed by drugs (n=8), hymenoptera venom (n=2), and cold (n=1). In five cases there was no identifiable cause. Among foods, cow's milk was the culprit agent in 27 children. The most severe reaction was a cardiorespiratory arrest. The most frequent symptoms were respiratory and cutaneous in 51 cases. Hypotension was present in nine cases. There were no fatalities. Most acute reactions were treated with corticosteroids and/or antihistamines. Adrenaline was used in only about one quarter of children. CONCLUSIONS The most important causes of anaphylaxis in our study were foods, and the most common symptoms were respiratory and cutaneous. The prevalence of anaphylaxis was higher in males and, in two thirds of patients there was a history of atopy. Despite being the primary and most important treatment for anaphylaxis, adrenaline is still used in only a minority of these cases.

Abstract
Ti-Si-C thin films were deposited onto silicon, stainless steel and high-speed steel substrates by magnetron sputtering, using different chamber configurations. The composition of the produced films was obtained by Electron Probe Micro-Analysis (EPMA) and the structure by X-ray diffraction (XRD). The hardness and residual stresses were obtained by depth-sensing indentation and substrate deflection measurements (using Stoney's equation), respectively. The tribological behavior of the produced films was studied by pin-on-disc. The increase of the concentration of non-metallic elements (carbon and silicon) caused significant changes in their properties. Structural analysis revealed the possibility of the coexistence of different phases in the prepared films, namely Ti metallic phase (alpha-Ti or beta-Ti) in the films with higher Ti content. The coatings with highest carbon contents, exhibited mainly a sub-stoichiometric fcc NaCI TiC-type structure. These structural changes were also confirmed by resistivity measurements, whose values ranged from 10(3) omega/sq for low non-metal concentration, up to 10(6) omega/sq for the highest metalloid concentration. A strong increase of hardness and residual stresses was observed with the increase of the non-metal concentration in the films. The hardness (H) values ranged between 11 and 27 GPa, with a clear dependence on both crystalline structure and composition features. Following the mechanical behavior, the tribological results showed similar trends, with both friction coefficients and wear revealing also a straight correlation with the composition and crystalline structure of the coatings.

Abstract
The study was designed to compare the response to almotriptan in migraine patients who take medication early in the course of the attack with that when medication is taken after pain has become moderate or severe. A randomized, four-arm, multicentre, multinational, double-blind, placebo-controlled trial of almotriptan (12.5 mg) comparing treatment administration when pain intensity was mild and within 1 h of headache onset vs. pain that had become moderate or severe was conducted. Of 491 migraineurs enrolled, 403 were evaluable [intention-to-treat population (ITT)]. Their mean age was 38 years, 84% were female and they had a mean of 3.7 attacks/month. Of these patients, 10% did not take medication according to their randomly allocated basal pain intensity (mild or moderate/severe) and were subsequently reassigned to that group for this analysis —'Act when Mild (AwM)' group. In the almotriptan arms, 53% of mild basal pain and 38% of moderate/severe basal pain patients were pain free at 2 h ( P = 0.03; primary end-point). Corresponding proportions in the placebo groups were 25% and 17% (statistically significant vs. respective almotriptan arms). Secondary end-points (ITT) were also significantly in favour of early intervention with almotriptan, both between and across treatment groups, such as sustained pain free: 45.6% vs. 30.5% ( P = 0.02). Adverse events were reported in < 5% of treated patients in all groups (NS), with no serious events. Treatment with almotriptan while migraine pain is still mild provides statistically significant and clinically relevant enhancements in efficacy compared with treatment when pain has reached higher severity levels.

Abstract
OBJECTIVE To compare almotriptan and zolmitriptan in the treatment of acute migraine. METHODS This multicentre, double-blind trial randomized adult migraineurs to almotriptan 12.5 mg (n = 532) or zolmitriptan 2.5 mg (n = 530) for the treatment of a single migraine attack. The primary end point was sustained pain free plus no adverse events (SNAE); other end points included pain relief and pain free at several time points, sustained pain free, headache recurrence, use of rescue medication, functional impairment, time lost because of migraine, treatment acceptability, and overall treatment satisfaction. RESULTS No significant difference was seen in SNAE (almotriptan 29.2% vs zolmitriptan 31.8%) or the other efficacy end points measured. The incidence of triptan-associated AEs and triptan-associated central nervous system AEs was significantly lower for patients receiving almotriptan compared to zolmitriptan. CONCLUSIONS Almotriptan and zolmitriptan were associated with similar efficacy and overall tolerability in the treatment of acute migraine. Almotriptan was associated with a significantly lower rate of triptan-associated AEs.

Abstract
GV150526 is a novel glycine antagonist at the NMDA receptor complex. It is a potent neuroprotective agent in animal models of acute stroke including permanent middle cerebral artery occlusion in the rat. GV150526 was very well tolerated in early human studies. The purpose of this randomised, double-blind, multicentre, placebo-controlled trial was to assess the safety and population pharmacokinetics of GV150526 in patients with a clinical diagnosis of acute stroke. Exploratory assessment of efficacy, quality of life and resource utilisation was also undertaken. Upon clinical diagnosis of acute stroke within 12 h of onset of symptoms, patients were treated with a loading dose of 800 mg GV150526 (or placebo), followed by 5 maintenance doses of 400 mg GV150526 (or placebo) given every 12 h over 3 days. Following observation of asymptomatic hyperbilirubinaemia, the maintenance dose was reduced mid-study to 200 mg. CT/MRI scanning was not mandatory prior to treatment. The study treated 128 patients (38 with GV 800 mg/400 mg, 48 with GV 800 mg/200 mg and 42 with placebo). Fewer patients with mild stroke (NIH scores < or =5) were enrolled in the GV150526-treated groups than in the placebo group (placebo 38%, GV 800 mg/400 mg 18%, GV 800 mg/200 mg 15%). There was also an imbalance in the proportion of patients with haemorrhagic strokes (placebo 5%, GV 800 mg/400 mg 3%, GV 800 mg/200 mg 15%). Mortality at 1 month was unbalanced between treatment groups, being 10, 18 and 17% in the placebo, GV 800 mg/400 mg and GV 800 mg/200 mg groups, respectively (no significant difference). Similarly, adverse events, though consistent with an acute stroke population, appeared more often in the GV 800 mg/200 mg group. Functional outcomes at 1 month also showed imbalances, the percentage of patients with a Barthel Index score of > or =95 at 1 month being 52, 39 and 27% in the placebo, GV 800 mg/400 mg and GV 800 mg/200 mg groups, respectively. These results probably reflect a prognostically significant baseline difference between the groups rather than the effect of GV150526. GV150526 was generally well tolerated in patients with a clinical diagnosis of acute stroke and formal efficacy studies were considered justified.

Abstract
PURPOSE To identify mutations in families with acute intermittent porphyria, an autosomal dominant inborn error of metabolism that results from the half-normal activity of the third enzyme in the heme biosynthetic pathway, hydroxymethylbilane synthase. METHODS Mutations were identified by direct solid phase sequencing. RESULTS Two novel missense mutations E80G and T78P and three previously reported mutations, R173W, G111R, and the splice site lesion, IVS1+1, were detected, each in an unrelated proband. The causality of the novel missense mutations was demonstrated by expression studies. CONCLUSION These findings provide for the precise diagnosis of carriers in these families and further expand the molecular heterogeneity of AIP.

Abstract
OBJECTIVE To assess the the effect of antiplatelet therapy on the severity of subsequent stroke in patients with stroke and TIA. BACKGROUND The Second European Stroke Prevention Study (ESPS2) recruited 6,602 patients in four treatment groups: placebo, 2 x 25 mg acetylsalicylic acid (ASA), 2 x 200 mg dipyridamole (DP), and the combination of 50 mg ASA and 400 mg DP per day. Seventy-six percent of the patients had had a stroke as the qualifying event, whereas 24% had a TIA. All patients were followed at 3-month intervals for 2 years. ESPS2 showed a benefit from antiplatelet treatment compared with placebo and an additional benefit using ASA and DP together compared with either of these antiplatelet agents alone. METHODS In the ESPS2, the study protocol included assessment of severity of end point stroke with the modified Rankin scale once the stroke had clinically stabilized, and no further impairment was observed. There were 824 new stroke events during follow-up. In 701 of them, the initial Rankin scale was known, and this was also evaluated after each nonfatal recurrent stroke. The difference in Rankin scale between treatment groups was analyzed after recurrent stroke, and the progress in Rankin scale between entry and recurrent stroke was quantified by calculating the number of patients with a change of one or more degrees in the scale. RESULTS There were no significant differences in these changes in Rankin scale between the treatment groups. The mean time to reach an end point of stroke was longest in patients who used ASA + DP (p = 0.057). However, there was no difference among the treatment groups in the time to death during follow-up. CONCLUSION This study suggests that antiplatelet therapy does not influence the severity of recurrent stroke as evaluated with the Rankin scale. However, antiplatelet therapy seems to lengthen the time the patient remains free from a recurrent stroke.

Abstract
BACKGROUND The Second European Stroke Prevention Study (ESPS2) was a randomized, placebo-controlled trial that investigated the efficacy of low-dose acetylsalicylic acid (ASA) and modified-release dipyridamole (DP), alone or in combination, in the secondary prevention of ischemic stroke. The trial demonstrated that the combination was significantly more effective than either agent used alone. The aim of the present study was to evaluate the influence of age on the efficacy of ASA and DP, alone or in combination, in the secondary prevention of stroke in the ESPS2 population. METHODS AND RESULTS A total of 6602 patients were recruited to the ESPS2 and there were 4 treatment groups: ASA (25 mg twice daily), DP (200 mg twice daily), ASA and DP in a combined formulation, or placebo. Primary endpoints were stroke, death, and stroke or death together. The endpoints evaluated in the present study were stroke, stroke and/or death, and vascular events. Stroke was the qualifying event in 76% of the patients, while 24% had a transient ischaemic attack. Patients were reviewed at 3-month intervals for 2 years. The study population consisted of 2565 (39%) patients aged less than 65 years, 2240 (34%) patients aged between 65 and 74 years, and 1797 (27%) patients aged 75 years and over. Advancing age was associated with an increased incidence of endpoints in all 4 treatment groups. The combination of ASA and DP significantly reduced the incidence of all endpoints, compared with placebo, in each age group. There was no influence of age on the efficacy of antiplatelet therapy for any of the evaluated endpoints. Relative risk reductions of treatment compared with placebo were 11.1-27.6% in the ASA group, 8.0-18.7% in the DP group, and 20.3-45.2% in patients receiving combination therapy. CONCLUSION This study clearly demonstrates that combination therapy with DP and ASA is superior to either agent used alone in the secondary prevention of ischemic stroke, irrespective of the age of the patient.

Abstract
In 1988, we undertook a randomized, placebo-controlled, double-blind trial to investigate the safety and efficacy of low-dose acetylsalicylic acid (ASA), modified-release dipyridamole, and the two agents in combination for secondary prevention of ischemic stroke. Patients with prior stroke or transient ischemic attack (TIA) were randomized to treatment with ASA alone (50 mg daily), modified-release dipyridamole alone (400 mg daily), the two agents in a combined formulation, or placebo. Primary endpoints were stroke, death, and stroke or death together. TIA and other vascular events were secondary endpoints. Patients were followed on treatment for two years. Data from 6,602 patients were analysed. Factorial analysis demonstrated a highly significant effect for ASA and for dipyridamole in reducing the risk of stroke (p < or = 0.001) and stroke or death combined (p < 0.01). In pairwise comparisons, stroke risk in comparison to placebo was reduced by 18% with ASA alone (p = 0.013); 16% with dipyridamole alone (p = 0.039); and 37% with combination therapy (p < 0.001). Risk of stroke or death was reduced by 13% with ASA alone (p = 0.016); 15% with dipyridamole alone (p = 0.015); and 24% with the combination (p < 0.001). The treatment had no statistically significant effect on the death rate alone. Factorial analysis also demonstrated a highly significant effect of ASA (p < 0.001) and dipyridamole (p < 0.01) for preventing TIA. The risk reduction for the combination was 36% (p < 0.001) in comparison with placebo. Headache was the most common adverse event, occurring more frequently in dipyridamole-treated patients. All-site bleeding and gastrointestinal bleeding were significantly more common in patients who received ASA in comparison to placebo or dipyridamole. We conclude that (1) ASA 25 mg twice daily and dipyridamole, in a modified-release form, at a dose of 200 mg twice daily have each been shown to be equally effective for the secondary prevention of ischemic stroke and TIA; (2) when co-prescribed the protective effects are additive, the combination being significantly more effective than either agent prescribed singly; (3) low-dose ASA does not eliminate the propensity for induced bleeding.

Abstract
We studied the activity of glutamate dehydrogenase (GDH) in leukocytes from 23 patients with dominantly inherited ataxia. All the patients were assessed with a rating scale for ataxias and met the clinical criteria for the diagnosis of Machado-Joseph disease. The mean age of onset of symptoms was 37.8, SD 13.4 years and the duration of the disease was 7.4, SD 4.9. Leukocyte GDH activity was significantly decreased (p < 0.001) when compared to 20 normal controls. These data extend previous reports indicating that a GDH deficiency is present in peripheral tissues from some patients with spinocerebellar degenerations. Furthermore, this study suggests that a genetic deficiency of GDH may underlie some forms of dominant ataxias; this deficiency may be marked in patients with Machado-Joseph disease and is not specific for any type of multiple system atrophy.

Abstract
We analysed the clinical features of 82 patients with dominantly inherited ataxia in a cohort survey. All patients fulfilled the diagnostic criteria for Machado-Joseph disease. The mean age of onset of symptoms was 39.8 (+/- 12.5) years and the duration of the disease was 9.2 (+/- 6.7) years. Ataxia, peripheral neuropathy, and fasciculation scores correlated with age of onset and duration of disease. Upper motor neuron scores failed to correlate with age of onset. In a follow-up study we analysed the clinical data of 46 patients two years after the first examination. A paired t-test was used to compare differences between observations. The results are in agreement with those of the cross-section in time, suggesting a deterioration of the symptoms with the evolution of the disease. We conclude that dynamic definition of the disease according to age of onset and duration of symptoms is preferable to subdivision into classical types.

Abstract
We have examined 138 cases of a disorder previously described in people of Portuguese origin and which has received many names. By computer analysis of 46 different items of a standardized neurological examination carried out in each patient, we have been able to delineate the main components of the clinical presentation, to conclude that the marked variability in clinical expressions does not negate the homogeneity of the disorder, and to describe the natural history of this entity which should be called, for historical reasons, "Machado-Joseph Disease". This hereditary disease has an autosomal dominant pattern of inheritance, presenting as a progressive ataxia with external ophthalmoplegia, and should be classified within the group of "Ataxic multisystem degenerations". When the disease starts before the age of 20, it may present with marked spasticity, of a non progressive nature but often so severe that it can be accompanied by "Gegenhalten" countermovements and dystonic postures but little frank dystonia. There are few true extrapyramidal symptoms except akinesia. When the disease starts after the age of 50, the clinical spectrum is mostly that of an amyotrophic polyneuropathy with fasciculations accompanying the ataxia. For all the other cases the clinical picture is a continuum between these two extremes, the main determinant of the clinical phenotype being the age of onset and a secondary factor, the place of origin of the given kindred. The ataxic and amyotrophic components are clearly progressive with time in contrast to the spasticity component. Although the majority of known cases are of Portuguese origin, this is not obligatory. The next research endeavour should be a search for the chromosomal site of the gene, using molecular biology technology such as those for recombinant DNA.

Abstract
SUMMARY:Determinations of CSF HVA before and after Probenecid administration were made in 41 patients with Parkinson’s disease. The means of HVA concentration were lower than those of controls but no correlation with clinical data was found. A negative correlation was demonstrated between post-probenecid HVA levels and subsequent score improvement with L-DOPA at 3,6 and 12 months. Post-probenecid HVA levels suggest that there are distinct forms of parkinsonism and could predict the response to L-DOPA therapy.
