RESUMO

BACKGROUND: The incidence of spontaneous intracerebral hemorrhage (SICH) is highest in very old elderlies (≥75 years). The increasing use of antithrombotic drugs is shifting the epidemiology of SICH towards predominance of lobar subtype, suggesting an incremented propensity of bleeding associated with underlying cerebral amyloid angiopathy. With population aging and antithrombotic use, a parallel raise of proportion of lobar SICH is occurring. Improvement of prognostication in this specific age group and SICH type is needed. Routine blood biomarkers can contribute to prediction of short-term mortality after SICH. OBJECTIVE: Our aim was to investigate the contribution of routine blood biomarkers for short-term mortality (30-days) in elderly patients with lobar SICH. METHODS: Retrospective analysis of consecutive 130 patients with ≥ 75 years and lobar SICH. The outcome was 30-day mortality. Logistic regression analysis was used to investigate whether admission routine biomarkers can be used as predictors. RESULTS: The case fatality was 40.8%. Admission glycaemia level, neutrophil to lymphocyte ratio and mean platelet volume were significantly different between groups (p = 0.001, p = 0.024, p = 0.038, respectively). There was no significant difference in all other routine biomarkers. On multivariate analysis, admission higher mean BG level (odds ratio [OR]: 1.010, 95% confidence interval [CI]: 1.001-1.019, p = 0.026) and neutrophil to lymphocyte ratio (OR: 1.070, 95% CI: 1.008-1.136, p = 0.027) emerged as predictors. CONCLUSION: In very old patients with lobar SICH, higher BG level and neutrophil to lymphocyte ratio are associated with increased risk of short-term death.

RESUMO

BACKGROUND: Neurocysticercosis (NCC) is severe and leading global cause of morbidity and mortality. The disease presents with a variety of clinical presentations from focal to diffuse neurological symptoms. Despite being an endemic country, there are no studies describing the clinico-epidemiological characteristics of NCC in Mozambique. Herein, we describe a consecutive cases series of NCC from the national reference Hospital in Maputo, capital of Mozambique. METHODS: Consecutive cases of NCC diagnosed during a 3-year period (January/2020-December/2022) were retrieved from the institutional clinical files and imaging database. RESULTS: Six cases of NCC were identified, with mean age of 43.1 years (range 26-66). Four were males (66.6 %). The median time from the beginning of clinical manifestations to the diagnosis was 6 months (range 3-18 months). All patients presented with severe parenchymal NCC, with seizures (n = 5, 83 %) being the most common manifestation. Other clinical manifestations were dementia (n = 1) and hydrocephalus (n = 1). The imaging showed multiple lesions at different stages, with half (n = 3) of them showing the coexistence of nodular calcified lesions at earlier stages (vesicular, colloidal and granular stages). Patients were treated with anthelminthic drugs, corticosteroids and anticonvulsants and no deaths to report. The 3rd month modified Rankin scale was ≤ 2 in 83 % of patients. CONCLUSION: In our case series, patients with NCC presented very late, with severe advanced stage disease, with multiple coexistent short and long-term brain lesions. These findings can be explained eventually because of the Maputo Central Hospital being national referral center receiving commonly more severe cases. Studies aiming to clarify the diagnosis pathways/barriers and NCC awareness among medical doctors working at primary and secondary health care level is mandatory to assess the real burden of NCC and implement timely diagnosis and care of patients affected by this neglected disease.

RESUMO

A myriad of neurological manifestations can occur in association with ketotic and non ketotic hyperglycaemic states. Contrary to diabetic coma, which is a universal complication under relatively established metabolic circumstances, the pathophysiology beyond hyperglycaemic-associated positive neurological manifestations, including seizures, remains to be elucidated. The occurrence of symptomatic focal epilepsy as a manifestation of diabetes-related hyperglycaemia is seldom reported. Herein, we present a case of focal epilepsy with alternating positive and negative neurological manifestations as the initial manifestation of diabetes-related hyperglycaemia. The electroencephalogram confirmed the diagnosis of focal occipital seizures, and the brain magnetic resonance imaging depicted the associated typical transient imaging findings in the occipital lobe. Seizures were refractory to antiepileptics, and symptomatic control was achieved after achieving normoglycemia. On follow-up, complete clinical and imaging recovery occurred. Reflex focal epilepsy in the context of hyperglycaemic states is a rare condition, and the possibility of misdiagnosis is likely high. As reported in similar cases, seizures can be resistant to antiepileptics. An important message to highlight is that seizures associated with hyperglycaemic status can be resistant to antiepileptic treatment and only cease with glycaemic control.

RESUMO

BACKGROUND: After onset of acute ischemic stroke (AIS), there is a limited time window for delivering acute reperfusion therapies (ART) aiming to restore normal brain circulation. Despite its unequivocal benefits, the proportion of AIS patients receiving both types of ART, thrombolysis and thrombectomy, remains very low. The organization of a stroke care pathway is one of the main factors that determine timely access to ART. The knowledge on organizational factors influencing access to ART is sparce. Hence, we sought to systematize the existing data on the type and frequency of pre-hospital and in-hospital organizational factors that determine timely access to ART in patients with AIS. METHODOLOGY: Literature review on the frequency and type of organizational factors that determine access to ART after AIS. Pubmed and Scopus databases were the primary source of data. OpenGrey and Google Scholar were used for searching grey literature. Study quality analysis was based on the Newcastle-Ottawa Scale. RESULTS: A total of 128 studies were included. The main pre-hospital factors associated with delay or access to ART were medical emergency activation practices, pre-notification routines, ambulance use and existence of local/regional-specific strategies to mitigate the impact of geographic distance between patient locations and Stroke Unit (SU). The most common intra-hospital factors studied were specific location of SU and brain imaging room within the hospital, and the existence and promotion of specific stroke treatment protocols. Most frequent factors associated with increased access ART were periodic public education, promotion of hospital pre-notification and specific pre- and intra-hospital stroke pathways. In specific urban areas, mobile stroke units were found to be valid options to increase timely access to ART. CONCLUSIONS: Implementation of different organizational factors and strategies can reduce time delays and increase the number of AIS patients receiving ART, with most of them being replicable in any context, and some in only very specific contexts.

RESUMO

Introduction: Parkinson's disease (PD) is associated with a progressive inability to accomplish essential activities of daily living (ADL) resulting in a loss of autonomy and quality of life. Accurate measurement of ADL in PD is important to monitor disease progression and optimize care. Despite its relevance, it is still unclear which measurement instruments are the most suitable for evaluating ADL in people with PD. Objective: To identify and critically appraise which measurement instruments have been used to assess ADL in PD. Methods: A systematic review was conducted using the databases CENTRAL, MEDLINE, and PEDro from their inception to October 2021 to identify all observational and experimental studies conducted in PD or atypical parkinsonism that included an ADL assessment. Titles and abstracts were screened independently by two authors. The clinimetric properties of the measurement instruments were assessed, and the instruments were classified as "recommended," "suggested," or "listed." Results: A total of 129 articles were included, with 37 measurement instruments used. The Unified Parkinson's Disease Rating Scale (UPDRS), the Schwab & England ADL scale (S&E scale), the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS), the Barthel Index, the Lawton-Brody Instrumental Activities of Daily Living Scale, the Functional Independence Measure (FIM) and the Alzheimer's Disease Cooperative Study - ADL (ADCS-ADL) scale were the seven most frequently cited measurement instruments. Of these, only two included an assessment of basic and instrumental ADL. Conclusion: MDS-UPDRS and the S&E scale were the only two scales that could be classified as recommended. For the MDS-UPDRS, either the full version or only Part II, which is focused on ADL, can be used. Future studies should explore the use of wearable devices to assess ADL remotely and more continuously.

RESUMO

INTRODUCTION: Following the hyperacute phase of spontaneous intracerebral hemorrhage (SICH), the severest form of stroke, pneumonia emerges as the leading cause of morbidity and mortality. Prevention of stroke associated pneumonia (SAP) is fundamental to improve the prognosis of SICH patients. AIM: Identify clinical, sociodemographic and process of care factors associated with occurrence of SAP after SICH in Algarve, southern Portugal. METHODS: Observational, retrospective study of community representative consecutive case series of patients with SICH admitted to the sole public hospital in the region. Logistic regression was used to identify predictors of SAP after SICH. RESULTS: A total of 525 patients were included. The mean age was 71 ( ± 13) years and 64% were men. SAP occurred in 165 (31.5%). Lower Glasgow Coma Scale score (GCS score): ≤ 8 (OR= 2.087; 95% CI= [1.027;4.424]; p = 0.042) and GCS 9-12 (OR= 1.775; 95% CI= [1.030;3.059]; p = 0.039); prolonged emergency room stay (OR= 8.066; 95%CI=[3.082;21.113]; p < 0.001) and hyperactive delirium (OR=2.860; 95% CI= [1.661;4.925]; p < 0.001) increased the likelihood of SAP. Being younger, ≤ 59 years (OR= 0.391; 95% CI= [0.168; 0.911]; p = 0.029) and 60-71 years (OR= 0.389; 95% CI= [0.185; 0.818]; p = 0.013); and having less severe SICH/intracerebral hemorrhage score (ICH score) ≤ 2 (OR=0.601; 95% CI= [0.370; 0.975]; p = 0.039), decreased the risk of SAP. CONCLUSION: After SICH, SAP occurs in approximately a third of patients. Non preventable (admission severity, ageing) and potentially preventable (prolonged emergency room stay, hyperactive delirium) determine the occurrence of SAP. Intensification of preventive intervention in high-risk patients, delirium prevention and improvement of the process of care can potentially reduce the occurrence of SAP after SICH.

RESUMO

Although more commonly seen in adult population, posterior reversible encephalopathy syndrome (PRES) can also be observed in pediatric patients. The etiopathogenesis of pediatric PRES is poorly understood, and the available evidence comes mostly from childhood cancer. Analysis of the sociodemographic and clinical characteristics of the different noncancer-related types can improve the understanding of pediatric PRES. Methods: Systematic review of characteristics and outcome of noncancer pediatric PRES. Primary sources of investigation were identified and selected through Pubmed and Scopus databases. The research was complemented by reference search in relevant publications. Study protocol was registered (Prospero CRD42020165798). Results: We identified 449 cases of noncancer pediatric PRES from 272 studies, median age 10 (newborn to 17 years), 49.9% girls. The 4 most common groups of conditions were renal 165 (36.7%), hematologic 84 (18.7%), autoimmune 64 (14.3%), and cardiovascular 28 (6.2%) disorders. The 4 most prevalent precipitants identified were hypertensive crisis 119 (26.5%), corticosteroids 56 (12.5%), immunosuppression drugs 44 (9.8%), and biologic drugs 14 (3.1%). Clinical presentations included seizures 100 (22.3%), headaches 22 (4.9%), encephalopathy 17 (3.8%), visual disturbances 6 (1.3%), and focal deficit 3 (0.7%). The distribution of lesions was (n = 380): combined anterior/posterior circulation (40.8%), isolated posterior circulation (24.1%), anterior circulation (6.2%), and deep structures (1.6%). Residual neurological deficits occurred in about 1 out 10 cases. Conclusion: Pediatric PRES differs from the adult in etiology, precipitants, and clinical manifestations. Renal diseases predominate, acute raised blood pressure is less frequent, and cortical deficits are rarer. In addition, the proportion of patients with combined anterior/posterior circulation was higher. Permanent neurological sequels can occur.

RESUMO

Background: In non-valvular-associated atrial fibrillation (AF), direct oral anticoagulants (DOAC) are as effective as vitamin K antagonists (VKA) for the prevention of acute ischemic stroke (AIS). DOAC are associated with decreased risk and severity of intracranial hemorrhage. It is unknown if different pre-admission anticoagulants impact the prognosis of AF related AIS (AF-AIS). We sought to analyze the literature to assess the association between pre-admission anticoagulation (VKA or DOAC) and admission severity of AF-AIS. Methods: A Systematic literature search (PubMed and ScienceDirect) between January 2011 to April 2021 was undertaken to identify studies describing the outcome of AF-AIS. Results: A total of 128 articles were identified. Of 9493 patients, 1767 were on DOAC, 919 were on therapeutical VKA, 792 were on non-therapeutical VKA and 6015 were not anticoagulated. In comparison to patients without anticoagulation, patients with therapeutical VKA and under DOAC presented with less severe stroke (MD −1.69; 95% CI [−2.71, −0.66], p = 0.001 and MD −2.96; 95% Cl [−3.75, −2.18], p < 0.00001, respectively). Patients with non-therapeutical VKA presented with more severe stroke (MD 1.28; 95% Cl [0.45, 2.12], p = 0.003). Conclusions: In AF-AIS, patients under therapeutical VKA or DOAC have reduced stroke severity on admission in comparison to patients without any anticoagulation, with higher magnitude of protection for DOAC.

RESUMO

INTRODUCTION: Patients with spontaneous intracerebral hemorrhage (SICH) face the worse functional and vital prognosis among all stroke subtypes. In cases of severe SICH, therapeutic inertia or nihilism complicates meaningful identification of outcome predictors. Therefore, we sought to investigate clinic-radiological and process of care predictors of short-term mortality in patients with mild to moderate SICH. PATIENTS AND METHODS: Observational retrospective community representative consecutive case series of patients from Algarve, southern Portugal. Logistic regression was used to identify predictors of short-term (30-day) death. RESULTS: Mortality was 23.9% (111/464). Most important predictors of death were unconsciousness at admission (OR = 12.392, 95% CI = 3.816-40.241, p < 0.001), hospital arrival ≥ 6 h after stroke onset (OR = 2.842, 95% CI = 1.380-5.852, p =.005), hematoma volume > 30 cc/cm3 (OR = 3.295, 95% CI 0 1.561-6.953, p =.002), intraventricular extension (OR = 2.885, 95% CI = 1.457-5.712, p =.002) and ≥ 24 h in the Emergency Department (OR = 19.675, 95% CI = 3.682-34.125, p =.009). Stroke Unit (SU) admission reduced the likelihood of death (OR = 0.293, 95% CI = 0.137-0.682, p =.002). CONCLUSION: The observed mortality is high. Apart from the traditional clinic-radiological factors, in mild to moderate SICH, process of care related factors have strong impact on mortality. These results highlight the need of continuous improvement of SICH care to improve the prognosis.

RESUMO

The artery of Percheron (AOP) is an abnormal variant of the arterial supply of the thalamus. Stroke caused by AOP occlusion is seldom reported. AOP leads to bilateral thalamic and rostral midbrain infarct presenting with unspecific manifestations. There are few descriptions of case series of stroke caused by AOP. We sought to review the clinicoradiological characteristics of AOP infarction from Algarve, Southern Portugal. Eight consecutive cases were retrospectively identified by searching the electronic clinical charts, as well as the stroke Unit database (2015-2020). Sociodemographic (age and gender) and clinicoradiological characteristics (etiological classification, admission severity, manifestations, and short- and long-term prognoses) were retrieved. The corresponding frequency of AOP infarction was 0.17% (95% confidence interval: 0.05-0.28). The mean age was 67.1 (range: 60-80) years. The range of stroke severity evaluated assessed by the National Institute of Health Stroke Scale ranged from 5 to 23 (median = 7.5). None of the patients receive acute ischemic stroke reperfusion treatment. AOP patterns were isolated bilateral paramedian thalamic ( n = 2), bilateral paramedian and anterior thalamic ( n = 2), and bilateral paramedian thalamic with rostral midbrain ( n = 4). Two patients (20%) died on the short term (30 days). At hospital discharge, six patients had functional disability of ≤2 on the modified Rankin scale. In the follow-up at 6 months, half ( n = 3) of the survivors had persistent hypersomnia and two had vascular dementia. Stroke from AOP presents with variable clinical and radiological presentations and patients do not receive alteplase. The short-term survivor and the long-term functional independency can be compromised after AOS infarct.

RESUMO

BACKGROUND: Stroke is the leading cause of cortical deafness (CD), the most severe form of central hearing impairment. CD remains poorly characterized and perhaps underdiagnosed. We perform a systematic review to describe the clinical and radiological features of stroke-associated CD. METHODS: PubMed and the Web of Science databases were used to identify relevant publications up to 30 June 2021 using the MeSH terms: "deafness" and "stroke", or "hearing loss" and "stroke" or "auditory agnosia" and "stroke". RESULTS: We found 46 cases, caused by bilateral lesions within the central auditory pathway, mostly located within or surrounding the superior temporal lobe gyri and/or the Heschl's gyri (30/81%). In five (13.51%) patients, CD was caused by the subcortical hemispheric and in two (0.05%) in brainstem lesions. Sensorineural hearing loss was universal. Occasionally, a misdiagnosis by peripheral or psychiatric disorders occurred. A few (20%) had clinical improvement, with a regained oral conversation or evolution to pure word deafness (36.6%). A persistent inability of oral communication occurred in 43.3%. A full recovery of conversation was restricted to patients with subcortical lesions. CONCLUSIONS: Stroke-associated CD is rare, severe and results from combinations of cortical and subcortical lesions within the central auditory pathway. The recovery of functional hearing occurs, essentially, when caused by subcortical lesions.

RESUMO

INTRODUCTION: the perception of Quality of Life (QoL) has been used to evaluate the treatment and evolution of several pathologies. QoL evaluation allows a better understanding of the patient and his adaptation to the disease. An observational, community-based and descriptive correlational study was carried out to analyze stroke survivors' perception of QoL. METHODS: consecutive case-series of stroke survivors (≥3 months) followed in a single public primary health center ("Tavira Primary Health Centre") from Algarve, southern Portugal. The Portuguese version of the World Health Organization Quality of life instrument was administered in 102 stroke survivors. RESULTS: Perception of QoL was associated (p < 0.05) with specific sociodemographic (age, sex, marital status, academic training), economic (monthly family income) and clinical factors (number of vascular risk factors, type of stroke, evolution, chronic mRankin score). On multivariate analysis, chronic mRankin score on physical (R2 = 0.406; F = 8.757; p < 0.001), psychological (R2 = 0.286; F = 5.536; p < 0.001) and general domain (R2 = 0.357; F = 7.287; p < 0.001); and family income (R2 = 0.160; F = 3.156; p < 0.005) on environmental domain, emerged as predictors of QoL. CONCLUSION: Different socio-demographic, economic and health factors are associated with post-stroke QoL. Description of QoL contributes to the overall evaluation of the impact of stroke on health and should be a priority for health professionals.

RESUMO

INTRODUCTION: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits. OBJECTIVE: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics. METHODS: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients were included. RESULTS: A total of 180 patients met the 2015 Wingerchuk NMOSD criteria, 77 were AQP4-antibody positive (Abs+), 67 MOG-Abs+, and 36 seronegative. Point prevalence on December 31, 2018 was 1.71/100,000 for NMOSD, 0.71/100,000 for AQP4-Abs+, 0.65/100,000 for MOG-Abs+, and 0.35/100,000 for seronegative NMOSD. A total of 44 new NMOSD cases were identified during the two-year study period (11 AQP4-Abs+, 27 MOG-Abs+, and 6 seronegative). The annual incidence rate in that period was 0.21/100,000 person-years for NMOSD, 0.05/100,000 for AQP4-Abs+, 0.13/100,000 for MOG-Abs+, and 0.03/100,000 for seronegative NMOSD. AQP4-Abs+ predominated in females and was associated with autoimmune disorders. Frequently presented with myelitis. Area postrema syndrome was exclusive of this subtype, and associated with higher morbidity/mortality than other forms of NMOSD. MOG-Ab+ more often presented with optic neuritis, required less immunosuppression, and had better outcome. CONCLUSION: Epidemiological/clinical NMOSD profiles in the Portuguese population are similar to other European countries.

RESUMO

INTRODUCTION: the prognosis of spontaneous intracerebral hemorrhage (SICH) remains poor. Understanding gender differences can clarify the clinico-epidemiological and process of care related factors that influence SICH prognosis. We analyzed the long-term gender differences of mortality after SICH in Algarve, southern Portugal. PATIENTS AND METHODS: analysis of consecutive community representative of SICH survivors (2009-2015). Logistic regression analysis and Kaplan-Meier method was used to assess gender differences on 1-year mortality and survival. We further analyzed if differences exist between 4 age and gender based subgroups (women <75 years, women ≥75 years, men <75 years, men ≥75 years). RESULTS: a total of 285 survivors were analyzed; majority men (66.3%). Women were 2 years older on average. Overall case fatality was 11.6% [CI: 8.3-15.8]. A non-statistically significant (P = .094) higher case-fatality rate was observed in women; men were more frequently admitted to stroke unit; women had more often poor functional outcome or modified Rankin scale (mRS) ≥3. Predictors of death were: being women with ≥ 75 years, in-hospital pneumonia and hospital discharge mRS ≥3. The likelihood of death was higher in women ≥75 years (OR = 2.91 [1.23-8.1], P = .035) in comparison to women <75 years and men ≥75 years. Women <75 years had the longest survivor time, whereas women ≥75 years the shortest survivor time (P < .001). CONCLUSION: gender and age interact to influence long-term mortality after SICH. Women ≥75 years are at increased risk of death and have reduced survival after SICH in southern Portugal. Further studies are needed to clarify the biological or social factors contributing for the poor prognosis in the very old women in the region.

RESUMO

BACKGROUND: Diffuse midline glioma (DMG) is one of the most aggressive pediatric tumors. Approximately 60% of pediatric DMG patients die within the first year of diagnosis. Complete clinical and radiological remission of DMG is extremely rare. The objective of this study was to describe a case of remission of pediatric DMG and to compare with similar cases published so far. RESULTS: DMG was diagnosed in a 2-year-old girl who presented with brainstem and increased intracranial pressure manifestations. Ventriculoperitoneal shunt and chemotherapy-based treatment were offered. From the diagnosis, in spite of progressive enlargement of the tumoral lesion, her clinical condition improved remarkably. After the end of chemotherapy, progressive and gradual imagiological improvements occurred. At the end of the 60th month of follow-up, she was asymptomatic with total remission. Six pediatric DMG cases, from birth to the age of 3, in whom remission occurred were found in the literature. Histology sample was available in two of them (fibrillary astrocytoma-WHO Grade II and anaplastic astrocytoma-WHO Grade III). None received chemotherapy or radiotherapy. CONCLUSION: Remission of pediatric DMG is extremely rare and reinforces the biological heterogeneity of the tumor. In the absence of reliable predictors of prognosis, offering the best supportive treatment, including neurosurgical interventions should be considered in similar cases.

RESUMO

AIM: The incidence of spontaneous intracerebral hemorrhage (SICH) increases with age. Data on SICH mortality in the very old are sparse. We aimed to describe the predictors of 30-day SICH mortality in the very elderly in southern Portugal. METHODS: A total of 256 community representative SICH patients aged ≥ 75 years (2009-2016) were included. Multiple logistic regression was used to identify predictors of 30-day mortality. RESULTS: Mean age was 82.1 years; 57.4% males. The 30-day case fatality was 38.7%. The frequency of patients taking anticoagulants (29.3% vs. 11.5%); comatose (46.9% vs. 2.5%); with hematoma volume ≥ 30 mL (64.6% vs. 13.4%); intraventricular dissection (78.8% vs. 27.4%) was higher in deceased patients (p < 0.05). Survivors were more often admitted to stroke unit (SU) (68.2 vs. 31.3%) and had lower mean admission glycaemia values (p < 0.05). The likelihood of death was increased in patients with higher admission hematoma volume (≥ 30 mL) (OR: 8.817, CI 1.753-44.340, p = 0.008) and with prior to SICH history of ≥ 2 hospitalizations OR = 1.022, CI 1.009-1.069, p = 0.031). Having higher Glasgow coma scale score, OR: 0.522, CI 0.394-0.692, p < 0.001, per unit was associated with reduced risk of death. Age was not an independent risk factor of short-term death. CONCLUSIONS: The short-term mortality is high in very elderly SICH. Prior to SICH history of hospitalization, an indirect and gross marker of coexistent functional reserve, not age per se, increases the risk of short-term death.
