Hemorrhagic Cerebrovascular Disease: An Unusual Presentation of Hyperhomocysteinemia / Accidente cerebrovascular hemorrágico: una inusual presentación de hiperhomocisteinemia / Acidente vascular cerebral hemorrágico: uma apresentação incomum da hiper-homocisteinemia

Introduction: Stroke is a major cause of morbidity and mortality worldwide, with hemorrhagic stroke being the deadliest form of acute stroke. Therefore, the cause of the event should be determined to direct the associated therapy and take preventive measures. Hyperhomocysteinemia has been described as a rare etiology of stroke. Although hyperhomocysteinemia has been associated with venous thrombotic events, altered endothelial function, and procoagulant states, its clinical role in stroke remains controversial. Case description: We present a case of a 60-year-old male patient with primary autoimmune hypothyroidism who presented with dysarthria, facial paresis, and left upper-limb monoparesis after sexual intercourse. A simple skull computed tomography scan showed hyperintensity in the right basal ganglion, indicating an acute hemorrhagic event. Etiological studies were performed, including ambulatory blood pressure monitoring, cerebral angiography, and transthoracic echocardiogram, which ruled out underlying vascular pathology. During follow-up, vitamin B12 deficiency and hyperhomocysteinemia were detected, without other blood biochemical profile alterations. Supplementation was initiated, and homocysteine levels gradually decreased, without new neurological deficits observed during follow-up. Conclusion: Quantification of homocysteine should be considered in patients with a cerebrovascular disease without apparent cause, as documenting hyperhomocysteinemia and correcting its underlying etiology are essential not only for providing appropriate management but also for preventing future events.

Introducción: el accidente cerebrovascular es una causa importante de morbilidad y mortalidad en todo el mundo, y el accidente cerebrovascular hemorrágico es la forma más mortífera de accidente cerebro- vascular agudo. La determinación de la causa del evento es esencial para dirigir la terapia asociada y poder tomar medidas preventivas. La hiperhomocisteinemia se ha descrito como una etiología poco frecuente de accidente cerebrovascular. Aunque esta se ha asociado con eventos trombóticos venosos, disfunción endotelial alterada y estados procoagulantes, sigue siendo controvertido su papel clínico en el accidente cerebrovascular. Descripción del caso: se presenta el caso de un hombre de 60 años con hipotiroidismo autoinmune primario que presentó disartria, paresia facial y monoparesia del miembro superior izquierdo después de un encuentro sexual. Una simple tomografía computarizada de cráneo mostró hipointensidad en la región del ganglio basal derecho, que indicaba un evento hemorrágico agudo. Se realizaron estudios etiológicos, incluyendo monitorización ambulatoria de la presión arterial, angiografía cerebral y ecocardiograma transtorácico, que descartaron patología vascular subyacente. Durante el seguimiento, se detectó deficiencia de vitamina B12 e hiperhomocisteinemia, sin otras alteraciones en el perfil bioquímico sanguíneo. Se inició la suplementación y los niveles de homocisteína disminuyeron gradualmente, sin observar nuevos déficits neurológicos durante el seguimiento. Conclusión: la cuantificación de homocisteína debe ser considerada en casos de enfermedad cerebrovascular sin causa aparente, dado que documentar la hiperhomocisteinemia y corregir su etiología subyacente es esencial no solo para proporcionar un manejo adecuado, sino también para prevenir eventos futuros.

Introdução: o acidente vascular cerebral (AVC) é uma das principais causas de morbidade e mortalidade em todo o mundo, sendo o AVC hemorrágico a forma mais letal de AVC agudo. A determinação da causa do evento é essencial para direcionar a terapia associada e poder tomar medidas preventivas. A hiperhomocisteinemia tem sido descrita como uma etiologia rara de acidente vascular cerebral. Embora a hiper-homocisteinemia tenha sido associada a eventos trombóticos venosos, disfunção endotelial alterada e estados pró-coagulantes, seu papel clínico no AVC permanece controverso. Descrição do caso: apresentamos o caso de um homem de 60 anos com hipotireoidismo autoimune primário que apresentou disartria, paresia facial e monoparesia do membro superior esquerdo após relação sexual. A tomografia computadorizada de crânio mostrou hipointensidade na região do gânglio da base direito, indicando evento hemorrágico agudo. Foram realizados estudos etiológicos, incluindo monitorização ambulatorial da pressão arterial, angiografia cerebral e ecocardiograma transtorácico, que descartaram patologia vascular subjacente. Durante o acompanhamento, foram detectados deficiência de vitamina B12 e hiper-homocistei- nemia, sem outras alterações no perfil bioquímico sanguíneo. A suplementação foi iniciada e os níveis de homocisteína diminuíram gradualmente, sem novos déficits neurológicos observados durante o acompanhamento. Conclusão: a quantificação da homocisteína deve ser considerada em casos de doença vascular cerebral sem causa aparente, pois documentar a hiper-homocisteinemia e corrigir sua etiologia subjacente é essencial não apenas para fornecer manejo adequado, mas também para prevenir eventos futuros.

Hematoma cerebral intraparenquimatoso e intraventricular por cocaína: reporte de un caso

Introducción: La cocaína es una de las sustancias psicoactivas más consumidas mundialmente. Es altamente adictiva y puede producir cuadros graves por su consumo, esporádico o habitual o, por su abstinencia, a nivel sistémico y neurológico. La exposición aguda a esta sustancia desencadena manifestaciones psiquiátricas inmediatas, como cambios en el afecto o conducta: sensación de irritabilidad, hiperactividad, ansiedad, desasosiego, euforia o psicosis. Esta sintomatología contrasta con inducción en ciertos casos de depresión, aislamiento o tristeza con la cronificación en su consumo. Además de los diversos efectos sensoperceptuales descritos, la sustancia puede generar daños neurológicos y/o cardiovasculares graves, como trastornos del ritmo cardíaco, arritmias malignas, emergencias hipertensivas, síndromes coronarios y enfermedades cerebrovasculares. Métodos: Presentamos el caso de un paciente quien ingresó al Hospital Universitario del Valle, en la ciudad de Santiago de Cali, departamento del Valle del Cauca, en Colombia, por un cuadro neurológico que permitía sospechar origen central. Este paciente no tenía factores de riesgo cardiovasculares, pero sí antecedentes de síndrome de Guillain Barré y de consumo de cocaína desde su adolescencia. Resultados: Al mencionado paciente se le realizaron múltiples estudios, destacándose los imagenológicos (tomografía, resonancia y angiorresonancia magnética de cerebro) y la estrategia invasiva de angiografía cerebral, en la cual logró documentarse que las manifestaciones neurológicas del paciente obedecían a una enfermedad cerebrovascular hemorrágica severa secundaria al consumo de cocaína. Conclusiones: Siempre indagar en pacientes con sangrados intraparenquimatosos el consumo de psicoactivos, en especial la cocaína, por su efecto lesivo sobre la vasculatura cerebral.

Introduction: Cocaine is one of the most widely consumed psychoactive substances worldwide. It is highly addictive and can produce serious systemic and neurological symptoms due to sporadic or habitual use or withdrawal. Acute exposure to this substance triggers immediate psychiatric manifestations such as changes in affect or behavior: feelings of irritability, hyperactivity, anxiety, restlessness, euphoria or psychosis; this symptomatology contrasts with induction in certain cases of depression, isolation or sadness with the chronification of its consumption. In addition to the various sensory-perceptual effects described, the substance can cause serious neurological and/or cardiovascular damage, such as heart rhythm disorders, malignant arrhythmias, hypertensive emergencies, coronary syndromes and cerebrovascular diseases. Methods: We present the case of a patient who was admitted to the Hospital Universitario del Valle, in the city of Santiago de Cali, department of Valle del Cauca, in Colombia, for a neurological condition that suggested a central origin. This patient had no cardiovascular risk factors, but had a history of Guillain Barré syndrome and cocaine use since adolescence. Results: The aforementioned patient underwent multiple studies, highlighting the imaging studies (CT, MRI and MRA of the brain) and the invasive strategy of cerebral angiography, in which it was possible to document that the patient's neurological manifestations were due to severe hemorrhagic cerebrovascular disease secondary to cocaine consumption. Conclusions: Always inquire in patients with intraparenchymal bleeds the consumption of psychoactives, especially cocaine, for its injurious effects on the cerebral vasculature.

The role of heparin-binding protein in predicting bacterial infection in traumatic intracerebral hemorrhage / 中华急诊医学杂志

Objective:To investigate the role of heparin-binding protein (HBP) as a predictor of early bacterial infections in patients with traumatic intracerebral hemorrhage.Methods:Patients with traumatic intracerebral hemorrhage admitted to the Emergency Department of the First Hospital of Shanxi Medical University from September 2021 to June 2022 were collected prospectively. Patients with bacterial infection diagnosed by pathogenic examination were classified as the infected group, and those with negative pathogenic examination were classified as the non-infected group. Peripheral blood HBP counts were measured within 48 h of admission, and general information and relevant laboratory tests were collected. The differences of the indicators between the two groups were compared, the receiver operating characteristic (ROC) curve was drawn, the predictive value of the indicators for patients with co-infection was assessed, and the valuable predictors were screened out using multivariate logistic regression analysis.Results:Eighty-five patients [44 males and 41 females, aged (55.09±1.18) years] , were included in the study. Among the patients included in the study, 39 patients had bacterial infection and 46 were non-infected. Patients in the infected group were older , and had more surgeries, higher respiratory rate and injury severity score, and higher levels of HBP [(33.00±3.49) ng/mL vs. (16.27±1.61) ng/mL, P<0.001], leukocytes, and neutrophils [(15.32±3.19) ×10 9/L vs. (6.69±0.57) ×10 9/L, P=0.005] than in the non-infected group, while the Glasgow Coma Scale [(8.72±0.63) vs. (11.37±0.48), P=0.001] was lower than that in the non-infected group, with statistically significant differences (all P<0.05). There was no significant differences in lymphocytes, red blood cells, platelets, calcium, procalcitonin and coagulation indexes between the two groups (all P>0.05). Logistic regression analysis showed that neutrophils ( OR=1.252, 95% CI: 1.075-1.457, P=0.004) and HBP ( OR=1.081, 95% CI: 1.025-1.141, P=0.004) were independent risk factors for infection in patients with traumatic cerebral hemorrhage. The area under ROC curve for HBP of diagnosing early co-infection in patients with traumatic intracerebral hemorrhage was 0.82 (95% CI: 0.71-0.88), the sensitivity was 92.31%, and the specificity was 52.17%. Conclusions:HBP is a valuable predictor of early traumatic intracerebral hemorrhage complicated with bacterial infection in the emergency department, and has a good supplementary value to the existing test indicators.

Short-term voluntary exercise enhances the activation of endogenous neural stem cells inintracerebral hemorrhage mice with hyperlipidemia / 西安交通大学学报(医学版)

【Objective】 To investigate the improvement of motor function recovery and the activation of endogenous neural stem cells (eNSCs) via voluntary exercise in mice with hyperlipidemia after intracerebral hemorrhage (ICH). 【Methods】 Four-month-old male Nestin-CreERT2: tdTomato transgenic mice were fed with high-fat diet (HFD) for eight weeks. Type Ⅳ collagenase was micro-injected into the corpus striatum to construct mouse ICH model with the help of stereotaxic apparatus. Voluntary exercise (wheel running) was initiated on the second day after ICH and monitored daily for seven days. Neurological severity score (NSS) and beam walking test were applied to evaluate motor function and coordination. Liver and brain tissues were collected at day 9 after ICH and sliced for staining. Then the Nestin-labeled cells, Ki67+, and doublecortin (DCX)+ in subventricular zone (SVZ) were counted to evaluate eNSCs activation. 【Results】 ① Compared with those of mice fed by chow diet (CD), the body weight, blood glucose level, concentration of lipid metabolism factors and the number of Nile Red positive cells in liver tissue were significantly higher in HFD-fed mice, confirming hyperlipidemia. ② Compared with the sham group, NSS score increased and the distance of cross-beam walking of ICH mice significantly decreased, showing the deficiency of motor function. It could be rescued by 7-day wheel running, as shown by a lower NSS score and a longer cross-beam walking distance. ③ Compared with the sham group, the number of Nestin+/Ki67+ cells decreased and Nestin+/DCX+ cells increased after ICH. After 7-day voluntary exercise, the number of Nestin+/Ki67+ cells decreased but that of Nestin+/DCX+ cells further increased significantly. However, compared with ICH, the increase of Nestin+/DCX+ cells in ICH+Ex was not significant. 【Conclusion】 Short-term voluntary exercise during the acute stage of ICH improved the recovery of motor function and enhance the proliferation of eNSCs in mice with hyperlipidemia. This provides a new idea for further developing ICH accelerated rehabilitation strategy based on eNSCs.

Research strategies and frontier technology advances in intracerebral pharmacokinetics / 中国药理学通报

The establishment of the cerebral pharmacokinetic model aims to truly reflect the disposition and course of action of drugs entering brain tissues, to ensure that brain-targeted drugs reach effective intracerebral concentrations, while preventing neurological damage from non-brain-targeted drugs, and to greatly improve effectiveness and safety. With the rapid development of research strategies and analytical techniques in the field of pharmacokinetics, intracerebral pharmacokinetic techniques have evolved from traditional brain tissue homogenization and cerebrospinal fluid extraction to in situ in vivo analysis techniques, from invasive techniques to non-invasive imaging techniques, and from the macroscopic tissue level to the microscopic cellular/subcellular level. A variety of pharmacokinetic research methods in brain are complementing each other and becoming increasingly perfect, gradually forming a comprehensive " subcellular-cellular-tissue" pharmacokinetic research system in brain, laying the foundation for elucidating the dynamic changes of drugs in brain and predicting the course of action of drugs in brain. This paper reviews the evolution and development of pharmacokinetic research strategies in brain, evaluates the advantages and limitations of various techniques and methods, and provides a reference for predicting the pharmacodynamic and toxic effects of drugs in brain tissues.

Association between gut microbiome and intracerebral hemorrhage based on genome-wide association study data / 中南大学学报(医学版)

OBJECTIVES@#Intracerebral hemorrhage (ICH) has the highest mortality and disability rates among various subtypes of stroke. Previous studies have shown that the gut microbiome (GM) is closely related to the risk factors and pathological basis of ICH. This study aims to explore the causal effect of GM on ICH and the potential mechanisms.@*METHODS@#Genome wide association study (GWAS) data on GM and ICH were obtained from Microbiome Genome and International Stroke Genetics Consortium. Based on the GWAS data, we first performed Mendelian randomization (MR) analysis to evaluate the causal association between GM and ICH. Then, a conditional false discovery rate (cFDR) method was conducted to identify the pleiotropic variants.@*RESULTS@#MR analysis showed that Pasteurellales, Pasteurellaceae, and Haemophilus were negatively correlated with the risk of ICH, whileVerrucomicrobiae, Verrucomicrobiales, Verrucomicrobiaceae, Akkermansia, Holdemanella, and LachnospiraceaeUCG010 were positively correlated with ICH. By applying the cFDR method, 3 pleiotropic loci (rs331083, rs4315115, and rs12553325) were found to be associated with both GM and ICH.@*CONCLUSIONS@#There is a causal association and pleiotropic variants between GM and ICH.

Improvement effect and mechanism of calycosin on acute inflammatory injury secondary to intracerebral hemorrhage / 中国药房

OBJECTIVE To investigate the improvement effect and mechanism of calycosin （CA） on acute inflammatory injury secondary to intracerebral hemorrhage. METHODS Male C57BL/6 mice were injected with type Ⅶ collagenase into the basal ganglia to establish an intracerebral hemorrhage model， which were divided into sham-operation group（phosphate buffered saline instead of collagenase）， model group， and different CA dose groups（15，30，60，120 mg/kg）. Based on the modified neurological severity score （mNSS） to screen the intervention doses， the volume of intracerebral hemorrhage， brain water content， the expressions of ionized calcium-binding adaptor molecule 1 （Iba1） in brain tissue， Toll-like receptor 4 （TLR4） and its downstream inflammatory factors [tumor necrosis factor-α （TNF-α）， inducible nitric-oxide synthase （iNOS）， interleukin-1β （IL- 1β）] in brain tissue， and the apoptosis of cells in brain tissue were detected. Primary microglia were cultured in vitro， and the expressions of TLR4 and its downstream inflammatory factors were detected. Primary neurons and primary microglia were co- cultured in vitro， and the apoptosis of neurons was detected. RESULTS The doses of 30 mg/kg and 60 mg/kg were selected as intervention doses of CA for subsequent experiments. Compared with the sham-operation group， the mice in the model group had cerebral hemorrhage， the volume of cerebral hemorrhage and brain water content were significantly increased （P＜0.05）； the positive expression rate of Iba1 protein in brain tissue was significantly increased， and the relative expression levels of TLR4， TNF-α， IL-1β and iNOS protein in brain tissue were up-regulated significantly. The apoptosis rate also increased significantly （P＜0.05）. Compared with model group， the above indexes of the mice in the 30 and 60 mg/kg CA groups were significantly improved （P＜0.05）. CA significantlyreduced the relative expression levels of TLR4 and its downstream inflammatory factors in microglia， and reduced the apoptosis of neurons in the co-culture system of primary neurons and primary microglia （P＜0.05）. CONCLUSIONS CA can exert a protective effect on the brain， which may be related to relieving the secondary acute inflammatory injury after intracerebral hemorrhage by inhibiting TLR4-mediated inflammatory response.

Fatal intracranial bleedings in a viper bite: A case report / 中华创伤杂志(英文版)

Viper bite envenomation represents a significant occupational hazard among agricultural workers in India. The viper bite envenomation is usually suspected when a patient presents with predominant local symptoms at the bitten site, including pain, swelling, and necrosis. Further, systemic findings such as diffuse intravascular coagulation, hypotension, and shock may alert physicians of viper bite envenomation rather than a neurotoxic snake bite. However, cerebral complications are rare in viper bites but may potentially fatal. Central nervous system involvement in a viper bite is either due to neurotoxins or hemorrhagins present in the venom, which may induce cerebral thrombosis, ischemia, infarction, and hemorrhage. Here we present a case of a previously healthy adult male who succumbed to extensive subarachnoid, intracerebral, and intraventricular hemorrhages involving bilateral cerebral hemispheres following viper snake bite envenomation. This report highlights the importance of anticipating cerebral complications in viper bite envenomation, a rare occurrence. It also emphasizes the need for early antisnake venom administration to prevent and control systemic envenomation and its complications.

Cerebral amyloid angiopathy in an octogenarian

Cerebral amyloid angiopathy presents with lobar intracerebral hemorrhage, dementia or tran sient neurological events. It occurs due to P-amyloid deposits in the media and adventitia of small arteries, leptomeningeal capillaries and the cerebral cortex. Its prevalence increases with age, and its association with cognitive impairment is well established. We present the case of an 80-year-old previously independent woman with no disabilities or cognitive impairment, and a history of well-controlled systemic arterial hypertension who consulted due to a de novo seizure and focal neurological deficits. On imaging follow up, two bilateral parietal-occipital macrohemorrhages were found, which occurred at two different times during the development of the clinical condition. These findings were attributed to cerebral amyloid angiopathy, and the patient ultimately died during this hospitalization. In this case presentation, we discuss the diagnostic criteria for considering the presence of cerebral amyloid angiopathy, its prognosis, and the reason it led to death. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2567).

La angiopatía amiloide cerebral se presenta con hemorragia intracerebral lobular, demencia o eventos neurológicos transitorios. Ocurre como resultado del depósito de (3-amiloide en la media y la adventicia de las arterias pequeñas, los capilares de las leptomeninges y la corteza cerebral. Su prevalencia aumenta con la edad y su asociación con deterioro cognitivo está bien establecido. Se presenta el caso de una mujer de 80 años, previamente independiente, sin discapacidad ni deterioro cognitivo, con antecedente de hipertensión arterial sistémica bien controlada, quien consultó por episodio convulsivo de novo y focalización neurológica. Durante el seguimiento imagenológico se documentó presencia de dos macrohemorragias parietooccipitales bilaterales, acontecidas en dos momentos diferentes durante la evolución del cuadro clínico, hallazgos que fueron atribuidos a la presencia de angiopatía amiloide cerebral, finalmente la paciente falleció durante dicha hospitaliza ción. En esta presentación de caso se discuten los criterios diagnósticos para considerar la presencia de angiopatía amiloide cerebral, el pronóstico y la razón que llevó a la muerte.

Recent Cyclones Causing an Increased Incidence of Intracranial Haemorrhage in India — A Cross-sectional Study

Background : Seasonal variations in the incidence of Intracerebral Haemorrhage (ICH) have been extensively evaluated in the studies conducted in various parts of the world. The prevalence per 100,000 person-years of spontaneous cerebral haemorrhage is regularly highest in the winter and lowest in the summer. However, these seasonal variations of ICH in India have not been comprehensively described in any published literature. Methodology : In this retrospective cross-sectional study, data of 15000 patients were collected from various State Government-owned Hospitals of India of the months April, May and June. The present study examined the association between temperature variations and spontaneous ICH incidence during recent severe Cyclonic Storms ‘Yaas’, and ‘Tauktae’ in India with the brain’s Computed Tomography (CT) scans. A CT brain persists in being the investigation of choice in the initial diagnosis of ICH, as it is readily available, accessible and fast. Results : During these Cyclones, there was a significant temperature drop associated with an increased incidence of ICH in the specified time. Conclusion : Sudden temperature drop during a Cyclone can cause spontaneous Hypertension, which causes rupture of arteries in the brain and results in Stroke. The Government, Physicians and the general public need to be made aware of such associations

Braden scale for predicting pneumonia after spontaneous intracerebral hemorrhage

SUMMARY OBJECTIVE: Stroke-associated pneumonia is an infection that commonly occurs in patients with spontaneous intracerebral hemorrhage and causes serious burdens. In this study, we evaluated the validity of the Braden scale for predicting stroke-associated pneumonia after spontaneous intracerebral hemorrhage. METHODS: Patients with spontaneous intracerebral hemorrhage were retrospectively included and divided into pneumonia and no pneumonia groups. The admission clinical characteristics and Braden scale scores at 24 h after admission were collected and compared between the two groups. Receiver operating characteristic curve analysis was performed to assess the predictive validity of the Braden scale. Multivariable analysis was conducted to identify the independent risk factors associated with pneumonia after intracerebral hemorrhage. RESULTS: A total of 629 intracerebral hemorrhage patients were included, 150 (23.8%) of whom developed stroke-associated pneumonia. Significant differences were found in age and fasting blood glucose levels between the two groups. The mean score on the Braden scale in the pneumonia group was 14.1±2.4, which was significantly lower than that in the no pneumonia group (16.5±2.6), p<0.001. The area under the curve for the Braden scale for the prediction of pneumonia after intracerebral hemorrhage was 0.760 (95%CI 0.717-0.804). When the cutoff point was 15 points, the sensitivity was 74.3%, the specificity was 64.7%, the accuracy was 72.0%, and the Youden's index was 39.0%. Multivariable analysis showed that a lower Braden scale score (OR 0.696; 95%CI 0.631-0.768; p<0.001) was an independent risk factor associated with stroke-associated pneumonia after intracerebral hemorrhage. CONCLUSION: The Braden scale, with a cutoff point of 15 points, is moderately valid for predicting stroke-associated pneumonia after spontaneous intracerebral hemorrhage.

Role of External Ventricular Drainage (EVD) in Treating Spontaneous Intraventricular Haemorrhage

Background: There is no consensus in the literature on the effects of the development of hydrocephalus on survival and disability after intracerebral haemorrhage (ICH) and the benefits of external ventricular drainage (EVD). This study is planned to describe the role of external ventricular drainage in treating patients of spontaneous, either primary or secondary, intraventricular haemorrhage with hydrocephalus.Material & Methods:A hospital based prospective interventional study was conducted in the Department of Neurosurgery of Dhaka Medical College Hospital, which is a tertiary level hospital, from April 2016 to September 2017.Total 42 patients of spontaneous intraventricular haemorrhage, either primary or secondary, with hydrocephalus were selected for this study. All the collected data were entered into IBM SPSS software, Version 24. For statistical analysis, paired t-test to compare the preoperative GCS with postoperative GCS at 24 hours was done.Results:Among 42 patients, age range was 26-75 years with the mean age 65.2 � 10.87 years. Male were 26 (61.9%) and female were 16 (38.1%). Male-Female ratio was 1.625:1. No patient needed conversion of EVD into VP shunt. EVD drain became blocked in 5 cases which were managed accordingly. 5 patients developed ventriculitis among which 2 patients died and rest 3 improved with antibiotics.Conclusions:The results of present study shows that EVD has a good role in the treatment of spontaneous IVH with hydrocephalus when ICH volume is low (<30ml) and modified Graeb Score is low (?10 found in this in this study. Preoperative higher GCS or initial improvement in GCS or initial improvement in GCS at 24 hours positively correlates with Glasgow outcome scale which is an indication of good function outcome.

Non Traumatic and Non Hypertensive Intracerebral Bleed: Causes and Imaging Evaluation

Background: Cross-sectional observational study was done in patients with non-traumatic, non-hypertensive intracerebral bleed undergoing cerebral angiography to study its different causes.Material & Methods:Patients with all age groups presenting to the emergency with acute non-traumatic intra-cerebral bleed undergoing cerebral angiography in our institution for a time period of 6 months with a total of 200 patients were included in the study. Data collected were analyzed with respect to causes, distribution of aneurysms. Suspected cases of hypertensive bleed were excluded from the study population.Results:Non-contrast computed tomographic images showed positive findings in the form of either intra-axial/extra-axial bleed or infarct in 95% of patients. However angiographic findings were positive in 52% of patients. Aneurysms were the most common positive angiographic findings (43% cases) with 95% of aneurysms were located in the circle of Willis. Majority of patients had solitary aneurysm while 6% had multiple aneurysms.Conclusions:Among all non-traumatic, non-hpertensive intracerebral bleed aneurysms accounts for majority of the causes. Other causes include intraparenchymal arterio-venous malformations, cerebral venous thrombosis with hemorrhagic infarct and dural arteriovenous malformations (AVM).

Scorpion sting affects many organ which can cause myocarditis, cardiogenic shock, acute renal dysfunction and respiratory collapse. Central nervous system involvement can cause encephalopathy, seizures, subarachnoid haemorrhage, and ischemic stroke. Cerebral bleed is a rare presentation of scorpion sting.Here we present a case of scorpion sting with unusual central nervous system (CNS) presentation of gangliocapsular bleed.

Potential drug-drug interactions among patients with spontaneous intracerebral hemorrhage treated at the Neurological Intensive Care Unit: a single-center experience

Abstract Our aim was to determine the prevalence of potential drug-drug interactions (pDDIs) and to identify relevant factors associated with the occurrence of the most dangerous or contraindicated pDDIs (pCDDIs) in hospitalized patients with spontaneous intracerebral hemorrhage (sICH). A retrospective cross-sectional study was performed enrolling all consecutive patients with sICH treated at the Neurological Intensive Care Unit, Clinical Center in Kragujevac, Serbia, during the three-year period (2012-2014). The inclusion criteria encompassed patients aged 18 years and over, those diagnosed with ICH, and those prescribed at least two drugs during hospitalization, while we did not include patients whose hospitalization lasted less than 7 days, those who were diagnosed with other neurological diseases and patients with incomplete medical files. For each day of hospitalization, the online checker Micromedex® software was used to identify pDDIs and classify them according to severity. A total of 110 participants were analysed. A high prevalence of pDDIs (98.2%) was observed. The median number of pDDIs regardless of severity, was 8.00 (IQR 4.75-13.00;1-30). The pairs of drugs involving cardiovascular medicines were the most commonly identified pDDIs. Twenty percent of the total number of participants was exposed to pCDDIs. The use of multiple drugs from different pharmacological-chemical subgroups and the prescribing of anticoagulant therapy significantly increase the chance of pCDDI (aOR with 95% CI 1.19 (1.05-1.35) and 7.40 (1.13-48.96), respectively). This study indicates a high prevalence of pDDIs and pCDDIs in patients with sICH. The use of anticoagulant therapy appears to be the only modifiable clinically relevant predictor of pCDDIs.

A cross-sectional study of early-onset epilepsy of intracerebral hemorrhage and construction of a risk prediction model / 中华危重病急救医学

Objective:To study the early-onset epilepsy of intracerebral hemorrhage and build a prediction model to evaluate its prediction efficiency.Methods:A cross-sectional investigation was conducted to construct a specialized optimized prediction model. The prediction model was converted into a visual optimized scoring scale, so as to quantify the probability of secondary epilepsy after intracerebral hemorrhage. Based on the current prediction model of acute cerebral infraction and post-stroke seizure (AIS-PSS), the evaluation efficacy of optimized score for secondary epilepsy after hemorrhagic stroke was explored.Results:① After sample size calculation and sufficient inclusion and exclusion, 159 patients with cerebral hemorrhage were continuously selected as the model group of this cross-sectional study. A total of 29 patients with early-onset epilepsy and 130 patients without secondary epilepsy were enrolled. The time span was from January 2021 to August 2021. In addition, 77 patients with acute cerebral hemorrhage from August 2021 to February 2022 were selected as the verification group, among which 12 patients had early-onset epilepsy and 65 patients had not any secondary epilepsy. ② There were significant differences in demographic characteristics such as diabetes history, cerebral infarction history, smoking history, National Institutes of Health Stroke Scale (NIHSS) score, intracerebral hemorrhage hematoma volume, serum creatinine (SCr), neuron-specific enolase (NSE), S-100 protein and intracerebral hemorrhage site between the two model groups with different prognosis (all P < 0.05). ③ The above indexes were included in univariate and multivariate Poisson regression analysis, and the results showed that the duration of diabetes [relative risk ( RR) = 1.229, 95% confidence interval (95% CI) was 1.065-1.896, P = 0.036], smoking history ( RR = 1.419, 95% CI was 1.133-2.160, P = 0.030), history of cerebral infarction ( RR = 1.634, 95% CI was 1.128-2.548, P = 0.041), hematoma volume of cerebral hemorrhage ( RR = 1.222, 95% CI was 1.024-2.052, P = 0.041), NES content ( RR = 1.146, 95% CI was 1.041-1.704, P = 0.032), were independent influencing factors to constitute the prediction model. The prediction model was converted into a visual optimized scoring scale in the form of a line diagram to obtain the prediction probability corresponding to the corresponding score. ④ Receiver operator characteristic curve (ROC curve) was used to test the evaluation efficiency of optimized score and AIS-PSS score for early-onset cerebral hemorrhage epilepsy. Relevant data of patients in the verification group were extracted according to the information of two scores, and the final score of each patient in the verification group was obtained. The score and prognosis were put into the ROC curve to evaluate the predictive ability of different prediction models. The results showed that the cut-off value of the optimized score and the AIS-PSS score were 144 points and 7 points, respectively, and the area under the ROC curve (AUC) and the Yoden index of the optimized score were slightly lower than the AIS-PSS score. However, compared with AIS-PSS score, there was no significant difference in the evaluation efficiency of optimized score for early-onset epilepsy ( Z = 1.874, P > 0.05). Conclusion:This study constructed a specific early-onset epilepsy prediction model for patients with hemorrhagic stroke, and transformed it into an optimized score that is easy for clinical use, and its evaluation efficiency is reliable.

Fecal microbiota transplantation in the treatment of acute intestinal pseudo obstruction secondary to intracerebral hemorrhage: a case report and literature review / 中华危重病急救医学

Objective:To analyze the clinical effects of fecal microbiota transplantation (FMT) on the treatment of acute intestinal pseudo obstruction (AIPO) secondary to intracerebral hemorrhage.Methods:The clinical data of a patient with AIPO secondary to intracerebral hemorrhage who was admitted to Nanfang Hospital of Southern Medical University was analyzed. The flora compositon between donor and patient was compared, finding the changes of intestinal flora before and after FMT (day 0 and day 25).Results:The main clinical findings in the patient were serious bloating, expansion of the intestinal canal and intra-abdominal hypertension. A week of conventional therapy was not effective, and the symptoms became progressively worse, affecting respiratory function.The result of fecal flora suggested the intestinal microbiota dybiosis, so FMT was attempted. After FMT, the patient's gastrointestinal symptoms were significantly relieved, and there were no further episodes within 25 days. The new result of fecal flora showed that the flora colonizing the intestine was dominated by Akkermansia and Bifidobacterium, with a significant decrease in potential pro-inflammatory and gas-producing bacteria and an increased gut microbiota diversity. The results trended to be partly consistent with the donor at 25 days after FMT: at the phylum level, the relative abundance of Bacterioidetes, Vereucomicrobia, Firmicutes and Actinobacteria were increased while Proteobacteria was decreased; at the class level, the relative abundance of Verrucomicrobiae, Bacterioidia, Actinobacteria, Coriobacteriia and Clostridia were increased and Gammaproteobacteria was decreased; at the order level, the relative abundance of Bacterioidales, Verrucomicrobiales, Clostridiale, Coriobacteriales were increased and Betaproteobacteriales, Enterobacteriales were decreased; at the family level, the relative abundance of Bifidobacteriaceae, Akkermansiaceae, Ruminococcaceae were increased and Enterobacteriaceae was decreased; at the genus level, the relative abundance of Akkermansia, Bifidobacterium were increased and Escherichia-Shigella, Klebsiella were decreased. At 1-year follow-up, the patient lived with self-care and scored 5 points in Glasgow outcome scale (GOS). Conclusions:FMT may provide clinical benefit in treated patients with AIPO secondary to intracerebral hemorrhage, probably by regulating the intestinal microflora, and re-establishing proper intestinal barrier, to maintain intestinal homeostasis.

The effect of neutrophil/lymphocyte ratio on the early-stage condition judgment and prognosis of intracercbral hemorrhage / 中国医师进修杂志

Objective:To investigate the relationship of neutrophil/lymphocyte ratio (NLR) and early hematoma enlargement (HE) of intracerebral hemorrhage (ICH).Methods:Retrospectively analyzed the clinical data of 360 patients with ICH who were diagnosed and admitted to the Affiliated Hospital of Xuzhou Medical University from January 2017 to December 2017.Among them, 198 patients were selected for this study. According to the 24 h checked CT, they were divided into the hematoma expansion (HE) group (87 patients) and the non-HE group (111 patients). The clinical data of the two groups and the changes of hematology and imaging were compared.Results:Univariate analysis showed statistically significant differences of two groups in systolic blood pressure, diastolic blood pressure, Glasgow coma scale (GCS) score, hematoma volume at admission: (180.45 ± 25.90) mmHg(1 mmHg = 0.133 kpa) vs. (171.81 ± 25.87) mmHg, (103.29 ± 14.26) mmHg vs. (97.98 ± 14.81) mmHg, (11.05 ± 2.02) scores vs. (13.04 ± 1.58) scores, (25.14 ± 14.88) ml vs. (13.57 ± 11.98) ml; and GCS score, NLR , hematoma volume at 24 h after admission: (7.54 ± 2.04) scores vs. (11.04 ± 2.12) scores, 12.79 ± 7.24 vs. 5.59 ± 3.59, (17.07 ± 8.95) ml vs. (7.97 ± 3.56) ml, there were significant differences ( P<0.05). Logistic regression analysis showed that NLR, GCS, hematoma volumeat 24 h after admission and number of island sign were independent correlated factors of HE ( P<0.05). Receiver operation characteristic(ROC) curve analysis showed that when the NLR at 24 h after admission cut off value was 7.65, the sensitivity of predicting HE in patients with ICH was 78.16%, the specificity was 81.98%, and the area under the ROC curve was 0.852 (95% CI 0.798-0.907, P<0.001). Conclusions:HE have association with NLR, hematoma volume change.
