Audit of Transient Ischaemic Attack (TIA) inpatient management: a retrospective assessment

@#The aim of this retrospective study was to audit the management of transient ischaemic attack (TIA) patients admitted in 2012 compared to a previous audit (2009 to mid-2010). Data were obtained by reviewing the electronic clinical records of patients. Data on patient demographics, patient assessment and management according to TIA guidelines were collected. A total of 61 patients were admitted to hospital with primary diagnosis of TIA. One in four patients had an alternative diagnosis. TIA severity (ABCD2 score) was not calculated in 13% of the patients. Most patients had computed tomography (CT) brain imaging performed. Antiplatelet therapy was not adjusted in 10% of patients. Carotid doppler ultrasound was not considered in 20% of the patients. Most of the carotid dopplers were done within one week. Only 6.6% of the patients were referred for carotid endarterectomy. Blood pressure medications were not optimised in 57.4% of the patients. Only 27.9% were prescribed statin therapy. Not all patients had documented ECG findings or discussion regarding anticoagulation. There was a 32.8% 3-month readmission rate. In 2012 several aspects of TIA guideline management were not done appropriately compared to the previous audit. The areas of improvement identified in this assessment include optimising antiplatelet therapy and blood pressure management, as well as timely carotid ultrasound for anterior circulation TIA. Further education and reiteration of guideline-based TIA management is recommended. A follow-up audit of the service is warranted

Rare mimicker of transient ischaemic attacks: the syndrome of transient headache and neurological deficits with cerebrospinal luid lymphocytosis

The syndrome of transient headache and neurologic deficits associated with cerebrospinal fluid lymphocytosis (HaNDL) is a benign and self limiting disorder characterized by 1 or more episodes of severe headache and transient neurologic deficits with lymphocytic pleocytosis in the cerebrospinal fluid. We report a case of a 30-year-old male who presented with four episodes of headache followed by hemi paresis and hemisensory loss in a week the patient was completely asymptomatic in between each episode of headache with neurological deficits. Persistent serial imaging to visualize the brain were normal with evidence of cerebrospinal fluid lymphocytosis, which lead to the diagnosis of HaNDL. We need to advocate a high degree of suspicion for HaNDL in the background of strong clinical history and findings, when imaging is normal.

The Study of Serum Uric Acid Levels in Ischemic Stroke Patients

Introduction: Stroke is defined by (WHO) World HealthOrganization as ‘a clinical syndrome consisting of rapidlydeveloping clinical signs of focal (or global in case of coma)disturbance of cerebral function lasting more than 24 hour orleading to death with no apparent cause other than a vascularorigin.’ There are few studies conducted in Indian scenario,which shows the role of serum uric acid in cases of acuteischaemic stroke. So the present study aimed at evaluatingrole of uric acid in assessing severity of acute ischemic stroke.Material and methods: It was an Analytical, Noninterventional Prospective study conducted among 100 casesof acute ischaemic stroke admitted in medicine ward and ICUat Krishna hospital, Karad over the period of 18 months, whofulfilled inclusion criteria were included in our study.Results: In the present study, serum uric acid levels and itsdistribution was carried out. Mean levels of Serum Uric acidwas 4.92 ± 1.89 mg/dl. Maximum value being 8.4 mg/dl andminimum value was 1.2 mg/dl.Conclusion: The severity of acute ischaemic stroke wasproved to be directly proportional to the mean serum uric acidlevels in the present study.

A Study of Risk Factors of Cerebrovascular Accident at a Tertiary Care Centre in Western UP

A stroke or CVA is defined by the abrupt onset of a neurologic deficit that is attributable to a focal vascular cause. Important modifiable risk factors include diabetes, hypertension, smoking, alcohol intake, sedentary life style, dyslipidemia, heart disease and OCP intake in females and non-modifiable risk factors include old age, gender predisposition and family history. The aim of study is to determine the types of stroke and presenting clinical features and modifiable and non-modifiable risk factors associated with development of stroke. Methods: The present study is a prospective observational study conducted in Teerthanker Mahaveer Medical College over a period of one year i.e January 2017 to January 2018.Total 110 cases presenting with stroke were included in the study. Results: The study shows that ischemic stroke is commoner than hemorrhagic stroke.The risk of stroke increases with age and common in males.Diabetes mellitus was seen in 29.1% cases presenting with stroke, 39.1% cases had hypertension.43.6% and 22.7 were smokers and alcoholic respectively. Dyslipidemia was present in 37.3% cases.15.4% cases had history of heart disease.17.2% cases had previous history of stroke. Conclusion: The modifiable risk factors pose a huge burden by increasing the morbidity and mortality due to stroke. Proper control of these risk factors can reduce the burden of disease.

Outpatient management of transient ischaemic attack

Stroke is a significant cause of death and disability in Singapore; in 2014, it was the fourth most common cause of death. Transient ischaemic attack (TIA) is defined as a transient episode of neurological dysfunction caused by focal brain, spinal cord or retinal ischaemia without evidence of acute infarction. The diagnosis of TIA/acute stroke needs to be considered in all patients who present with sudden focal neurological dysfunction. Prompt referral for assessment, neuroimaging and intervention provides the best chance for neurological recovery and/or minimising further neurological damage. Primary care physicians have a crucial role in TIA/stroke prevention and management. This includes referring patients with suspected acute TIA/stroke to hospitals with stroke treatment facilities immediately; managing the modifiable risk factors of cerebral ischaemia; continuing prescription of antiplatelet agents and/or anticoagulation where indicated; and teaching patients to recognise and respond to suspected cerebral ischaemia using the FAST (face, arm, speech, time) acronym.

Dual Antiplatelet Therapy after Noncardioembolic Ischemic Stroke or Transient Ischemic Attack: Pros and Cons

Dual antiplatelet therapy simultaneously blocks different platelet activation pathways and might thus be more potent at inhibiting platelet activation and more effective at reducing major ischemic vascular events compared to antiplatelet monotherapy. Aspirin plus clopidogrel dual therapy is now the standard therapy for patients with acute coronary syndrome and for those undergoing percutaneous coronary intervention. However, dual antiplatelet therapy carries an increased risk of bleeding. Patients with ischemic stroke or transient ischemic attack (TIA) are generally older and likely to have a fragile cerebrovascular bed, which further increases the risk of systemic major bleeding events and intracranial hemorrhage. Clinical trials and meta-analyses suggest that in comparison to antiplatelet monotherapy, dual antiplatelet therapy initiated early after noncardioembolic ischemic stroke or TIA further reduces the rate of recurrent stroke and major vascular events without significantly increasing the rate of major bleeding events. In contrast, studies of long-term therapy in patients with noncardioembolic ischemic stroke or TIA have yielded inconsistent data regarding the benefit of dual antiplatelet therapy over monotherapy. However, the harm associated with major bleeding events, including intracranial hemorrhage, which is generally more disabling and more fatal than ischemic stroke, is likely to increase with dual antiplatelet therapy. Physicians should carefully assess the benefits and risks of dual antiplatelet therapy versus antiplatelet monotherapy when managing patients with ischemic stroke or TIA.

Juxtacortical Spots on Fluid-Attenuated Inversion Recovery Images in Cryptogenic Transient Ischemic Attack

BACKGROUND AND PURPOSE: Juxtacortical spots are detected frequently on fluid-attenuated inversion recovery (FLAIR) images, but have not been extensively researched in patients with transient ischemic attack (TIA). We hypothesized that juxtacortical spots on FLAIR images are partly associated with right-to-left shunt (RLS) in TIA without clear etiology. The possibility of an association between the presence of RLS and juxtacortical spots on FLAIR images in patients with TIA without clear etiology was investigated, and the imaging findings of patients with and without RLS were compared. METHODS: This was a retrospective study of TIA patients who visited our tertiary stroke center consecutively within 72 hours of TIA onset. Cryptogenic TIA was defined as no clear etiology despite a routine diagnostic workup. The presence of RLS was examined by transcranial Doppler with an agitated saline test or transesophageal echocardiography. Juxtacortical spots were defined as small and round hyperintensities in the juxtacortex on FLAIR images, excluding white-matter hyperintensities. RESULTS: Of the 132 patients with cryptogenic TIA examined for this study, 70 (53.0%) had RLS. Juxtacortical spots on FLAIR images were detected more frequently in patients with RLS than in those without. The independent factors for the presence of juxtacortical spots were RLS [odds ratio (OR)=3.802, 95% confidence interval (95% CI)=1.74-8.2; p=0.001] and age (OR=1.058, 95% CI=1.01-1.10; p=0.004) by multivariate analysis. The number of juxtacortical spots was significantly higher among patients with a moderate-to-large RLS than in those with a small or no RLS. CONCLUSIONS: The findings of the present study demonstrate a significant association between the presence of RLS and the occurrence of juxtacortical spots on FLAIR images in patients with cryptogenic TIA.

Establishment of Reference Range of Serum Ferritin by Turbidimetric Immunoassay in Korean First Time Blood Donors / 대한수혈학회지

BACKGROUND: Regular blood donation can lead to iron deficiency. Serum ferritin is sensitive indicator of body iron depletion. The aim of this study is to evaluate serum ferritin reagents using the turbidimetric immunoassay (TIA) and to establish a reference range in first time blood donors in Korea. METHODS: The study was prospectively conducted, between Feb. 2011 and Apr. 2011, on 120 male and 120 female blood donors at five blood centers. Serum ferritin was determined by TIA using two brands of reagents (Beckman Coulter Inc., USA; HBi, South Korea) and two automated chemistry analyzers (AU640, Beckman Coulter Inc.; Hitachi7180, Hitachi High-Technologies Corp., Japan). Precision, linearity, limit of detection, analytical measurement range and correlation with chemiluminescent immunoassay (CLIA) were evaluated. A reference range for serum ferritin in first time donors was established. RESULTS: The coefficients of variation of precision were less than 4%. Linearity was observed up to 312.7~450 microg/L depending on which reagent used. Both reagents had good correlation with CLIA results. Serum ferritin levels for first time donors showed left skewed distribution. The reference ranges for males and females were 34.1~385.9 microg/L and 6.8~121 microg/L using Beckman Coulter (AU) reagent, and 18.7~271.3 microg/L and 4~83.7 microg/L using HBi (AU) reagent, and 15.2~274.7 microg/L and 6~84 microg/L using HBi (Hitachi) reagent. CONCLUSION: A reference range for serum ferritin in first time donors in Korea was established using automated chemistry analyzers with inexpensive TIA reagents.

The study on dynamic CT perfusion imaging and in recurrence of TIA / 中国神经精神疾病杂志

Objective Evaluation of cerebral blood flow in patients with transient ischemic attack (TIA) using cerebral CT perfusion imaging.Methods CT perfusion scan was performed on a consecutive series of 20 patients with clinical definite TIA.Following their initial CT scan at acute stage of TIA, patients underwent two repeat CT perfusion scanning of region of interest at acute stage and one month after symptom remission.Results Mild to moderate decrease in regional cerebral blood flow (rCBF) and unchanged or mildly decrease in regional cerebral blood volume (rCBV) were observed at acute stage in the majority cases.Normal cerebral perfusion was found in 12 cases and mild to moderate decrease of rCBF in 8 cases one month after TIA.During the one-year follow-up period, all of 12 cases with normal cerebral perfusion did not have recurrence while among 8 cases with mild to moderate decrease of rCBF at initial scan, 6 cases had recurrent TIA or cerebral infarction and 2 cases did not have recurrence.Patients with more severe cerebral perfusion defects usually had a shorter interval time between two attacks.Conclusions Intensive intervention should be performed on patients with severe and long lasting decrease of cerebral perfusion.

Effect of urgent carotid endarterectomy on operative risk and benefit / 中国现代普通外科进展

Objectives:The time of Carotid intervention for recently symptomatic,severe carotid stenosis which cause a transient ischemic attack or minor stroke is still a controversial issue.Early studies showed that carotid endarterectomy (CEA) caused a high risk if performed within days follow an acute ischemic stroke.However,The National Stroke Strategy posted by UK Department of Health advocated that this situation should be regarded as an emergency procedure,and carotid intervention should ideally be performed within 48 hours.We designed this study to discuss the effect of urgent CEA on operative risk and benefit.Methods: we analyze 12 urgent CEA with primary closure performed during 1996 to 1998.All 12 patients were underwent CEA within 2 weeks,and 2 of them within 2 days.Operative risks and overall benefit from surgery were discussed in relation to the time from the last symptomatic event to CEA.Results: 2 urgent CEA performed in 2 days are recovery uneventful.1 of 12 patients,who underwent urgent CEA within 2 weeks,occurred restenosis after 3 months follow up.No 30-day perioperative recurrent TIA,stroke and death.Conclusions:CEA performed within 2 weeks is feasible and reliable procedure in preventing recurrent TIA and stroke after presenting manifestations.The future aim is to perform CEA within 48 hours after TIA or stroke symptoms.

@#Objective To use the multi-slice CT(MSCT)cerebral perfusion imaging and CT angiography(CTA)in the clinical diagnosis of transient ischemic attack(TIA).Methods 20 cases with transient ischemic attack within 48 h were examined with 16-slice CT perfusion imaging(CTPI)and CTA in head and neck.The interesting regional cerebral blood flow(rCBF),cerebral blood volume(rCBV)and the time to peak(rTP)were analyzed.Results The rTP of affected side delay compared with that of the healthy(t=3.04,P=0.008).CTA showed the responsible vascular stenosis or occlusion in varying degrees.There was not significant correlationship between rTP and vascular stenosis(r=0.32,P=0.17).Conclusion Cerebral perfusion imaging and head and neck CTA can provide valuable information for diagnosis and treatment of TIA.

Changes of Anterior Chamber Depth and Angle After Cataract Surgery Measured by Anterior Segment OCT

PURPOSE: To report the change of anterior chamber parameters according to cataract severity after cataract surgery and to determine its relationship to the severity of cataract by using anterior segment optical coherence tomography. METHODS: We measured the anterior chamber parameters in 19 eyes of 14 patients before, 1 week after, and 1 month after cataract surgery by slit lamp-adapted optical coherence tomography (SL-OCT). The measured parameters were as follows : the anterior chamber depth (ACD), the angle-opening distance 250 micrometer from the scleral spur (AOD250), the angle-opening distance 500 micrometer from the scleral spur (AOD500), and the trabecular-iris angle (TIA). We analyzed the relationship between the severity of cataract and the change of the anterior chamber parameters. RESULTS: The ACD, AOD250, AOD500, and TIA increased significantly at postoperative 1 week (P=0.000, 0.002, 0.005, 0.022) and 1 month (P=0.000, 0.004, 0.001, 0.002). The preoperative parameters were negatively correlated with the differences between the postoperative 1 week and preoperative parameters (gamma=-0.834, -0.591, -0.421, -0.826) and between postoperative 1 month and preoperative parameters (gamma=-0.659, -0.700, -0.770, -0.821). The change of parameters at postoperative 1 week (by N P=0.959, 0.916, 0.824, 1.000, by C P=0.454, 0.665, 0.578, 0.578) and 1 month (by N P=0.858, 0.973, 0.959, 0.959, by C P=0.999, 0.207, 0.950, 0.981) were not significantly different according to the severity of cataract (N, C). CONCLUSIONS: Our results showed that cataract surgery significantly deepened the anterior chamber and widened its angle. The shallower and narrower the preoperative anterior chamber depth and angle were, respectively, the greater the postoperative changes of anterior chamber depth and angle were.

Psychologic Investigation of Hypertensive with Transient Ischemic Attack: 56 Cases Report / 中国康复理论与实践

@#Objective To investigate the psychologic characteristics of the hypertensive with transient ischemic attack(TIA). Methods 56 hypertensive patients with TIA were surveyed with Symptom Checklist 90 (SCL-90), Eysenck Personality Questionnaire (EPQ), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS). Results and Conclusion The score in interpersonal sensitivity and paranoid factors of SCL-90 were below the norm obviously(P<0.05), the score of other factors were higher than the norm(P<0.01). Somatization, obsessive-compulsive, anxiety correlated negatively with E scale, while hostility, phobia anxiety, anxiety correlated positively with N scale. 71.4% patients appeared depression while 78.6% patients appeared anxiety in differently degree. Depression and anxiety correlated positively with the times of TIA, especially the anxiety.

Characteristics of Cerebral Artery Stenosis for Patients with Transient Ischemic Attack and Related Cardiovascular Risk Factors / 中国康复理论与实践

@#Objective To evaluate the localization and the correlation with cardiovascular risk factors of cerebral arteries damage in patients with transient ischemic attack (TIA). Methods Digital subtraction angiography (DSA) was performed in the 97 patients with TIA. The localization, the degree of stenosis, the numbers of the arteries involved and their correlation with the cardiovascular risk factors were analyzed. Results DSA showed occlusive findings of cerebral arteries in 91.8% of the patients, and 68 cases (76.4%) among them were involved more than one artery. The proximal internal carotid arteries (35.5%) and the proximal vertebral arteries (28.2%) were the most frequently involved in this series. And the number of the arteries involved and the degree of stenosis were positively correlated with the level of risk factors. Conclusion There is a high incidence of cerebrovascular stenosis in patients with TIA. Most of them are involved more than one artery. The degree of the stenosis is positively related with the quantity of the risk factors.

Relationship between Duration of Transient Ischemic Attacks and Prognosis:36 Case Report / 中国康复理论与实践

@#ObjectiveTo explore the relationship between the duration, MRI characters and prognosis in transient ischemic attack (TIA). Methods36 TIA cases were retrospectively analyzed according to the duration and Magnetic Resonance Imaging Diffusion Weighted Imaging(MRI-DWI). They were divided into two groups, Group A (13 cases) in which TIA continued within 1 h and Group B (23cases) in which TIA continued for 1～24 h. The patients were followed up 3 months and 12 months later. ResultsMRI abnormalities could be found with MRI-DWI in 2 cases in Group A, but 17 cases in group B(χ2=11.416,P=0.001). 1 case in Group A and 14 cases in Group B occurred cerebral infarction within a year(χ2=9.663,P=0.004). ConclusionThe longer TIA duration, the worse the prognosis.

Comparison of Total Intravenous Anesthesia and Combined Inhalation and Intravenous Anesthesia in Lower Limbs Orthopedics for Patients with Cerebral Palsy / 中国康复理论与实践

@#Objective To compare the characteristics of total intravenous anesthesia (TIA) with manual assisted ventilation and combined inhalation and intravenous anesthesia (CIIA) with mechanical ventilation in lower limbs orthopedics for patients with cerebral palsy.Methods 50 patients with cerebral palsy undergoing scheduled lower limbs orthopedics were randomly divided into the TIA group and CIIA group with 25 cases in each group. The patients of the TIA group were treated with manual assisted ventilation. Those of the CIIA group were treated with fast induction, endotracheal intubation, inhalated and intravenous anesthetics maintaining the anesthesia and mechanical ventilation. The recovery time after operation and post-operative side effects including nausea, vomiting, and psychomotor agitation of all patients were observed.Results The recovery time of the patients in the CIIA group was significantly longer than that in the TIA group ( P<0.01), and post-operative psychomotor agitation was significantly higher than that in the TIA group ( P<0.05). However, there was no significant difference in nausea or vomiting found between two groups ( P>0.05).Conclusion Patients treated with TIA is easier to recovery and has fewer side effects than those treated with CIIA.

Influence of Acupuncture on Cephalic Acupuncture Points Region Over the Brain-stem Evoked Potential of Patients Suffering Insufficient Blood-Supply of Vertebral Basilar Artery / 中国中医药信息杂志

Objective From the angle of electrophysiology, go further into the mechanism of action of acupuncture treatment to the insufficient blood-supply of vertebral basilar artery and at the same time, make a comparison of the effects between the acupuncture on cephalic meridian points and zonation cephalic acupuncture. Methods Through the contrast before and after adopting the self-acupuncture on the testees of 28 cases (including healthy persons of seven cases and TIA patients of 21 cases), observe the change of immediate effect of all waves latent period values of BAEP. Results The BAEP wave latent period of healthy persons (exclusive of I wave of auditory fainting region) assumes a relative delay within the physiological range and by comparison between points and region, the delay of V-wave Baihui point is evidently higher than that of auditory fainting region. However, the latent period of all waves of TIA patients is relatively moved up, especially there are evident differences before and after the I-wave acupuncture is carried out. Viewing from the comparison between points and region, there is no significant difference. Conclusion The function of acupuncture lies in the adjustment of antagonistic body state and it is most effective under the pathological state. Acupuncture will play the main role of excitation to the auditory nerve conduction of BAEP of TIA patients (from cochlea to midbrain) and the influence over the peripheral nerves is more sensitive than over the center ones. Although points and region have their own relative specificities, there is no significant difference between them.
