Intracranial bleeding

Frontoethmoidal encephalocele represents protrusion of meninges and brain in a sac through a defect in the anterior skull base, mostly as swelling over the nose. Rarely it is associated with facial dysmorphism and palatal cleft. There are various perioperative concerns like airway difficulties, leaking from the swelling causing fluid and electrolyte disturbances, risk of infection, compression of the swelling causing a rise in intracranial pressure, bleeding, hypothermia, etc., In neonates, these challenges rise exponentially because of the inherent difficulties in dealing with this group of patients...

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by a low platelet count with increased risk of bleeding, and viral infection may trigger ITP. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection-induced ITP has been increasingly reported. We systemically reviewed the previously reported cases of SARS-CoV-2 infection-induced ITP and identified a total of 105 patients from 68 studies. The median age was 61 years, and 14 patients (12%) were < 18 years old (pediatric cases)...

Secondary brain injury (SBI) occurs with a lag of several days post-bleeding in patients with aneurysmal subarachnoid hemorrhage (aSAH) and is a strong contributor to mortality and long-term morbidity. aSAH-SBI coincides with cell-free hemoglobin (Hb) release into the cerebrospinal fluid. This temporal association and convincing pathophysiological concepts suggest that CSF-Hb could be a targetable trigger of SBI. However, sparse experimental evidence for Hb's neurotoxicity in vivo defines a significant research gap for clinical translation...

BACKGROUND: In recent years, unruptured intracranial aneurysms have been found more frequently, and endovascular coiling has become an increasingly popular treatment. METHODS: Computer databases were searched between 1990 and 2018; the databases included Medline, EMBASE, the Cochrane library, and three Chinese domestic databases. We included controlled clinical studies. Two researchers extracted data and assessed the included studies. A meta-analysis was performed...

Acute kidney injury (AKI) is one of the most common organ dysfunctions impacting ICU (intensive care unit) patients. Early diagnosis using the various classification systems and interventions that can be aided by use of biomarkers are key in improving outcomes. Once the patient meets criteria of AKI, many patient specific factors determine the optimal timing for and mode of renal replacement therapy. There are several special considerations in surgical ICU patients with AKI including management of intracranial hypertension in those with cerebral edema, anticoagulation in high-risk bleeding patients, and use of contrast imaging...

BACKGROUND: High risk of intracranial hemorrhage (ICH) is a leading reason for withholding anticoagulation in patients with atrial fibrillation (AF). We aimed to develop a claims-based ICH risk prediction model in older adults with AF initiating oral anticoagulation (OAC). METHODS: We used US Medicare claims data to identify new users of OAC aged ≥65 years with AF in 2010-2017. We used regularized Cox regression to select predictors of ICH. We compared our AF ICH risk score with the HAS-BLED bleed risk and Homer fall risk scores by area under the receiver operating characteristic curve (AUC) and assessed net reclassification improvement (NRI) when predicting 1-year risk of ICH...

OBJECTIVE: Physicians vary in their computed tomography (CT) scan usage. It remains unclear how physician gender relates to clinical practice or patient outcomes. The aim of this study was to assess the association between physician gender and decision to order head CT scans for older emergency patients who had fallen. METHODS: This was a secondary analysis of a prospective observational cohort study conducted in 11 hospital emergency departments (EDs) in Canada and the United States...

Objective: To investigate the safety and accuracy of CT-guided intracranial puncture biopsy and the possible influencing factors of postoperative bleeding complications. Methods: A case series study. A retrospective analysis was conducted on 101 patients who underwent CT-guided intracranial puncture biopsy at the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2021. The basic data of patients and the safety and accuracy of CT-guided intracranial puncture biopsy were analyzed statistically...

INTRODUCTION: The awareness of nonocclusive thrombus has increased with the increasing frequency of imaging methods used for acute ischemic stroke; however, the best treatment for nonocclusive thrombi is still unknown. In this study, we examined how anticoagulants affect supra-aortic artery nonocclusive thrombus and clinical outcomes. MATERIALS AND METHODS: This study included 52 patients with transient ischemic attack or stroke who were diagnosed with nonocclusive thrombi on computed tomography angiography at admission...

INTRODUCTION: The management of cervical artery dissections (CAD) is poorly standardized given the scarce number of prospective studies comparing medical and interventional approach to CAD. The aim of the present study is to perform a systematic review and meta-analysis of studies on the treatments of CAD. METHODS: Systematic review and meta-analysis - pre-registered on PROSPERO (CRD42022297512) and performed according to the PRISMA guidelines searching in three different databases (PubMed, Embase and Cochrane Database) - of studies on medical or interventional approach to the CAD...

Considerable advances in the diagnosis and treatment of cancer have made a huge impact on morbidity and mortality from neoplastic diseases. However, cancer remains the leading cause of death across the world. This is a retrospective study carried out at a tertiary cancer care centre (Kidwai Memorial Institute of Oncology, Bangalore) in South India. Case records of all cancer patients who died while receiving inpatient treatment between January 2022 and December 2022 under the Department of Medical Oncology were reviewed and studied...

BACKGROUND: Intraparenchymal hemorrhage at the operative site is one of the major complications of brain surgery. It is unusual to occur at a site remote from the operative site, but when it happens, it may cause significant morbidity and mortality. CASE DESCRIPTION: We report the case of a 27-year-old male who presented with complaints of paresthesias over the left side of his face and decreased hearing from the left ear for two years. His radiology was suggestive of a large left cerebellopontine angle epidermoid cyst...

Type 3 von Willebrand disease (T3VWD) is a rare inherited bleeding disorder caused by the absence of von Willebrand factor (VWF). The traditional treatment for T3VWD has been VWF concentrates, but their effectiveness may be limited due to the development of alloantibodies. Emicizumab, a bispecific mAb, has shown promise in treating hemophilia A and is being studied as prophylaxis for T3VWD. In this case series, two patients with T3VWD received emicizumab prophylaxis and experienced a significant reduction in bleeding episodes and improved quality of life with fewer healthcare encounters...

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Head computed tomography (CT) is frequently utilized for evaluating trauma-related characteristics, selecting treatment options, and monitoring complications in the early stages. This study assessed the relationship between cranial CT findings and early and late neurological outcomes in pediatric TBI patients admitted to the pediatric intensive care unit (PICU). The study included children aged 1 month to 18 years who were admitted to the PICU due to TBI between 2014 and 2020...

IMPORTANCE: Diltiazem, a commonly prescribed ventricular rate-control medication for patients with atrial fibrillation, inhibits apixaban and rivaroxaban elimination, possibly causing overanticoagulation. OBJECTIVE: To compare serious bleeding risk for new users of apixaban or rivaroxaban with atrial fibrillation treated with diltiazem or metoprolol. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study included Medicare beneficiaries aged 65 years or older with atrial fibrillation who initiated apixaban or rivaroxaban use and also began treatment with diltiazem or metoprolol between January 1, 2012, and November 29, 2020...

INTRODUCTION: Endovascular treatment of wide neck aneurysms remains complicated with a determined and continuous technological effort towards treatment options that can offer safer and efficacious outcomes. The Woven Endobridge device was introduced in 2010 and has become a mainstay endovascular treatment for wide neck and large intracranial aneurysms. A recent review of the Woven Endobridge Clinical Assessment of Intrasaccular Aneurysm Therapy (WEBCAST) and WEBCAST2 trials and the five-year follow-up of patients was published...

Spontaneous intracranial hypotension (SIH) commonly results from ventral spinal cerebrospinal fluid (CSF) leaks and epidural patches are advocated as first-line treatment. Complications such as superficial siderosis can arise but have previously been reported only in the context of long-term persistent, ongoing, CSF leak and SIH. We report a case of a patient with SIH from a ventral spinal CSF leak that was treated with epidural patching and experienced complete resolution of SIH. Four years later SIH symptoms recurred, and brain magnetic resonance imaging unexpectedly showed the interval accumulation of hemosiderin pigmentation on the cerebellum and brainstem during the period when the patient was without symptoms of SIH...

Objectives : To review the evidence on the effectiveness and safety of low-dose-rivaroxaban 2.5 mg twice daily (LDR) in patients with coronary artery disease (CAD) and/or peripheral artery disease (PAD) taking antiplatelets. Methods : We performed a systematic review and meta-analysis of randomized controlled trials (RCTs). Efficacy endpoints were cardiovascular events (CVEs), myocardial infarction, stroke, all-cause, and cardiovascular death. Any, major, fatal bleeding, and intracranial hemorrhage (ICH) were safety endpoints...

The well preserved skeleton of Joseph Huber, a very well-known historical character of the 19th century Munich, also nicknamed "Finessen-Sepperl", is the starting point of the reconstruction of life and death of this historical individual. He was known as a postilion d´amour (love's messenger) of the Royal Bavarian capital with numerous comments and anecdotes and a few biographical sketches that indicate he remained well until the last few years of his life where requests for his duties lessened. The skeleton shows a small-sized male individual with almost complete loss of teeth, but otherwise very well-mineralized bone, having suffered from three episodes of trauma - an old-healed incomplete femoral neck fracture leading to severe osteoarthrosis, a clavicle fracture of the medial third with a few weeks old callus formation, and fresh serial rib fractures along with severe skull trauma with fractures of the os temporale and petrosum, presumably leading to intracranial bleeding and finally death...

Although generally well tolerated compared with chemotherapy, molecular targeted therapy used in metastatic melanoma may be associated with life-threatening toxicity. We report the case of a patient with metastatic melanoma treated by dabrafenib plus trametinib who developed intracranial hemorrhage. Physicians should be aware of this rare but life-threatening adverse event of B-rapidly accelerated fibrosarcoma (BRAF) and mitogen-activated protein kinase kinase (MEK). However, they should be careful about the bleeding origin, which can prove to be a new onset of melanoma metastasis or anticoagulation overdose, or even an uncontrolled arterial hypertension...
