Comparing the Comprehensive Stroke Ward Versus Mixed Rehabilitation Ward-The Importance of the Team in the Acute Stroke Care in a Case-Control Study.

BACKGROUND AND PURPOSE: Ischemic stroke is one of the most frequent causes of death in Brazil. Many measures have been taken to reduce this tragic outcome, and one of those is the implementation of stroke units in hospitals. The aim of the present study is to analyze the in-hospital complications for patients with ischemic stroke admitted in a comprehensive stroke ward (CSW) as compared to patients admitted in a mixed rehabilitation ward (MRW). METHODS: A retrospective interventional study with historic controls of patients admitted to the Neurology Division between January 2010 and October 2013. Patients admitted between January 2010 and September 2012 were included in the MRW group, and patients admitted from October 2012 until October 2013 were included in the CSW group. Throughout the whole study period, the same team assisted all the patients. Both groups were paired in relation to age and gender. The rate of in-hospital complications, mortality, and independency on discharge were evaluated in both groups. RESULTS: Each group was comprised of 91 patients. There were no statistically significant differences for any of the risk factors analyzed between the 2 groups nor for outcome measures-in-hospital complications, mortality, and independence on discharge. CONCLUSION: The present study demonstrated that in-hospital complications, independence on discharge, and mortality have similar rates in patients admitted to an MRW compared to patients admitted to a CSW, when the same staff provided them with specialized in-hospital care. EVIDENCE LEVEL: Case-control study-Evidence Level 3.

Sodium nitroprusside: low price and safe drug to control BP during thrombolysis in AIS.

This study analyzes the use of sodium nitroprusside (SN) as an option to reduce blood pressure (BP) below 180/105 mmHg during the management of acute ischemic stroke (AIS) in patients submitted to intravenous thrombolysis.Method The sample was composed by 60 patients who had AIS and were submitted to intravenous rtPA, split in two groups: half in the control group (CG) with BP < 180/105 mmHg and half in SN group with BP > 180/105 mmHg. Outcome variables were any hemorrhagic transformation (HT); the presence of symptomatic HT, National Institute of Health Stroke Scale (NIHSS) after 24 hours of treatment; the independence on discharge and death until three months after stroke onset.Results There were no statistical differences between both groups to any of the outcome variables analyzed.Conclusion The SN might be safe for BP control during thrombolysis to AIS.

Is point-of-care accurate for indicating thrombolysis in anticoagulated patients on oral anticoagulation treatments?

UNLABELLED: The use of oral anticoagulation treatment (OAT) in patients with an international normalized ratio (INR) higher than 1.7 is a contraindication to thrombolysis in acute ischemic stroke. The aim of the present study is to compare the use of point-of-care (POC) coagulometers to the standard coagulation analysis (SCA) procedure of the INR as a decision-making test for use with patients taking OAT. METHOD: Eighty patients on chronic OAT underwent a POC and an SCA during a regular outpatient evaluation. RESULTS: When comparing the abilities of the POC test and the SCA test to identify adequate levels for thrombolysis (≤1.7), the POC had a sensitivity of 96.6% (95%CI 88.4-99.1) and a specificity of 60.0% (95%CI 38.6-78). POC overestimated INR levels by 0.51 points compared to the SCA test. CONCLUSION: POC has a high sensitivity compared to the SCA test for the identification of patients within the cut-off point for thrombolysis.

Valores acima de 1.7 no RNI de pacientes em uso de terapia anticoagulante (ACO) é uma contraindicação para a trombólise no AVC isquêmico. O Objetivo do presente estudo é comparar o teste capilar rápido (TCR) com o exame tradicional de RNI como método de decisão para indicação de terapia trombolítica em pacientes em uso de ACO. Método: Oitenta pacientes em uso crônico de ACO foram submetidos ao TCR e ao exame tradicional durante consulta ambulatorial. Resultados: Ao serem comparados os resultados do TCR com o exame tradicional com o ponto de corte de 1,7 de RNI, o teste rápido teve sensibilidade de 96,6% (IC95% 88,4-99,1) e especificidade de 60,0% (IC95% 38,6-78). O TCR superestimou os níveis de RNI em 0,51 pontos comparado ao exame tradicional. Conclusão: O TCR apresentou elevada sensibilidade, comparado ao exame tradicional para a identificação de pacientes em uso de ACO com indicação de trombólise. .

Electrophysiologic characteristics of tremor in Parkinson's disease and essential tremor.

UNLABELLED: Tremor in essential tremor (ET) and Parkinson's disease (PD) usually present specific electrophysiologic profiles, however amplitude and frequency may have wide variations. OBJECTIVE: To present the electrophysiologic findings in PD and ET. METHOD: Patients were assessed at rest, with posture and action. Seventeen patients with ET and 62 with PD were included. PD cases were clustered into three groups: predominant rest tremor; tremor with similar intensity at rest, posture and during kinetic task; and predominant kinetic tremor. RESULTS: Patients with PD presented tremors with average frequency of 5.29±1.18 Hz at rest, 5.79±1.39 Hz with posture and 6.48±1.34 Hz with the kinetic task. Tremor in ET presented with an average frequency of 5.97±1.1 Hz at rest, 6.18±1 Hz with posture and 6.53±1.2 Hz with kinetic task. Seven (41.2%) also showed rest tremor. CONCLUSION: The tremor analysis alone using the methodology described here, is not sufficient to differentiate tremor in ET and PD.

Os tremores observados no tremor essencial (TE) e na doença de Parkinson (DP) costumam apresentar perfis eletrofisiológicos específicos, embora amplitude e frequência possam ter grandes variações. Objetivo: Apresentar os resultados dos exames eletrofisiológicos na DP e no TE. Método: Pacientes foram avaliados em repouso, com postura e em ação. Foram incluídos 17 pacientes com TE e 62 com DP. Casos de DP foram divididos em três grupos: predomínio de tremor de repouso; tremor com intensidade semelhante em repouso, postura e tarefa cinética e tremor cinético predominante. Resultados: Pacientes com DP apresentaram tremores com frequência média de 5,29±1,18 Hz em repouso, 5,79±1.39 Hz com postura e 6,48±1,34 Hz com tarefa cinética. Tremor no TE apresentou frequência média 5,97±1,1Hz em repouso, 6,18±1Hz com postura e 6,53±1,2 Hz com tarefa cinética. Sete (41,2%) também apresentaram tremor de repouso. Conclusão: A análise do tremor per se, usando os métodos descritos neste estudo, não é suficiente para diferenciar o tremor no TE e DP. .

Neuroleptic malignant syndrome.

Neuroleptic malignant syndrome (NMS) is a potentially fatal adverse event associated with the use of antipsychotics (AP). The objective of this study was to investigate the profile of cases of NMS and to compare our findings with those published in similar settings. A series of 18 consecutive patients with an established diagnosis of NMS was analyzed, gathering data on demography, symptoms and signs. Two thirds of all cases involved woman with a past medical history of psychiatric disorder receiving relatively high doses of AP. The signs and symptoms of NMS episodes were similar to those reported in other series and only one case had a fatal outcome, the remaining presenting complete recovery. As expected, more than two thirds of our cases were using classic AP (68%), however the clinical profile of these in comparison with those taking newer agent was similar. Newer AP also carry the potential for NMS.

A síndrome neuroléptica maligna (SNM) é um evento adverso potencialmente fatal associado ao uso de antipsicóticos (AP). O objetivo deste estudo foi investigar as características clínicas de cases da SNM e comparar nossos resultados com os publicados na literatura. Uma série de 18 pacientes com diagnóstico confirmado de SNM foram analisados, associando dados demográficos, apresentação clínica, diagnóstico e tratamento. Dois terços dos casos envolveram mulheres com antecedentes psiquiátricos que recebeceram doses relativamente altas de AP. Os sinais e sintomas foram semelhantes àqueles já relatados na literatura e a maioria dos pacientes teve uma recuperação completa, exceto por um caso com desfecho fatal. Houve predomínio de pacientes que usam medicamentos neurolépticos clássicos (68 por cento), porém não houve diferença nas manifestações destes casos em relação àqueles que usavam AP novos. AP mais novos também têm o potencial de causar SNM.

Neurological diagnoses in the emergency room: differences between younger and older patients.

UNLABELLED: Neurological diseases are prevalent in the emergency room (ER). The aim of this study was to compare the neurological diagnoses between younger and older patients evaluated in the ER of a tertiary care hospital. METHOD: Patients admitted to the ER who required neurological evaluation in the first 24 hours were separated into two groups based on age, ≤50 years old and >50 years old. RESULTS: Cerebrovascular disease (59.6% vs. 21.8%, p<0.01) was most frequent in the >50 years old group. Seizures (8.1% vs. 18.6%, p<0.01) and primary headache (3.7% vs. 11.4%, p<0.01) were most frequent in the ≤50 years old group. CONCLUSION: The current study demonstrated that these three neurological diagnoses represented the majority of the neurological evaluations in the ER. National guidelines for ER teams that treat these prevalent disorders must be included in clinical practice and training.

Doenças neurológicas são prevalentes na sala de emergência (SE). O objetivo deste estudo é comparar a ocorrência de diagnósticos neurológicos entre pacientes jovens e idosos atendidos na SE de um hospital terciário. MÉTODO: Pacientes admitidos na SE que necessitaram avaliação neurológica nas primeiras 24 horas após a admissão foram separados em dois grupos baseados na idade, <;50 anos de idade e >50 anos de idade. RESULTADOS: Doença cerebrovascular foi o diagnóstico mais comum nos pacientes >50 anos (59,6 por cento vs. 21,8 por cento, p<0,01). Convulsões (8,1 por cento vs. 18,6 por cento, p<0,01) e cefaléias primárias (3,7 por cento vs. 114 por cento, p<0,01) foram mais frequentes no grupo <;50 anos. CONCLUSÃO: O presente estudo demonstrou que esses três diagnósticos neurológicos representam a maioria das avaliações neurológicas na SE. Diretrizes nacionais para os profissionais emergencistas que tratam estas doenças devem ser incluídos na prática clínica e no treinamento médico.

Hemorrhagic stroke after naphazoline exposition: case report.

Ten percent of all strokes are due to spontaneous cerebral hemorrhages. They are associated to drugs (licit and illicit) in 9.5% of all cases in young adults. This is a case report of a 44-year-old man, without previous morbidities, who presented a sudden onset headache and arterial hypertension 24 hours after use of naphazoline as nasal decongestant. Cranial tomography showed right thalamus hemorrhage. Cerebral angiography showed no aneurisms, vascular malformations or vasculitis. No other risk factors were found during investigation in this patient and the stroke was attributed to naphazoline exposition.

Hemorrhagic stroke after naphazoline exposition: case report

Dez por cento de todos os eventos vasculares encefálicos são devido às hemorragias intracerebrais espontâneas, associados a drogas (lícitas e ilícitas) em 9,5% de todos os casos em adultos jovens. Relatamos o caso de um homem de 44 anos de idade, sem doenças prévias, que apresentou cefaléia súbita e hipertensão arterial 24 horas após o uso de congestionante nasal contendo nafazolina. A tomografia de crânio evidenciou hemorragia talâmica. Durante a investigação não foram encontrados outros fatores de risco e a hemorragia foi atribuída à exposição à nafazolina.
