Aneurysmal subarachnoid hemorrhage: current concepts and updates

ABSTRACT Aneurysmal subarachnoid hemorrhage is a condition with a considerable incidence variation worldwide. In Brazil, the exact epidemiology of aneurysmal SAH is unknown. The most common presenting symptom is headache, usually described as the worst headache ever felt. Head computed tomography, when performed within six hours of the ictus, has a sensitivity of nearly 100%. It is important to classify the hemorrhage based on clinical and imaging features as a way to standardize communication. Classification also has prognostic value. In order to prevent rebleeding, there still is controversy regarding the ideal blood pressure levels and the use of antifibrinolytic therapy. The importance of definitely securing the aneurysm by endovascular coiling or surgical clipping cannot be overemphasized. Hydrocephalus, seizures, and intracranial pressure should also be managed. Delayed cerebral ischemia is a severe complication that should be prevented and treated aggressively. Systemic complications including cardiac and pulmonary issues, sodium abnormalities, fever, and thromboembolism frequently happen and may have na impact upon prognosis, requiring proper management.RESUMO Hemorragia subaracnoidea aneurism ática (aHSA) é uma condição com grande variação de incidência mundialmente. No Brasil, não dispomos de números epidemiológicos exatos. A apresentação clínica mais comum da HSA é a ce...

ConclusionCongenital piriform sinus fistula is an important cause of deep neck abscess in children. The presence of purulent gas-liquid equilibrium or air shadow in cervical-enhanced computed tomography or ultrasound suggests a high possibility of the presence of an internal fistula, and endoscopic low temperature ablation can be done at the same time as the diagnostic endoscopy.ResumoIntroduçãoA fístula congênita do seio piriforme é uma doença relativamente rara na prática clínica; a maioria se manifesta na infância; entretanto, os médicos geralmente t&ec...

ConclusionsPillar suture combined with tonsillectomy may reduce postoperative bleeding incidence despite increasing pillar edema in pediatric tonsillectomy. Postoperative pain-relief, palatal hematoma, palatal discomfort sensation, site infection, and velopharyngeal insufficiency were not significantly altered compared to tonsillectomy alone. However, further studies are needed to corroborate the results of this study.ResumoIntroduçãoDiversas técnicas cirúrgicas têm sido utilizadas na tonsilectomia no intuito de reduzir complicações.ObjetivosAvaliar os efeitos da sutura dos p...

Perrin, Christopher Bull, Sheila BlackAbstractLocal anaesthetics (LA) are weak bases consisting of a lipophilic aromatic ring linked to a hydrophilic tertiary amine by either an ester or amide bond. It is this chemical link that enables classification of the LA. They exist in solution as an equilibrium of ionized and unionized forms. The unionized form is free to diffuse across the axonal membrane, but it is the ionized form which then binds and blocks the intracellular portion of the voltage gated sodium c...

Conclusion: It may be employed either alone or in combination with cryotherapy, existing chemotherapy, bypass surgery or radiations to achieve the optimal results in these patients. Nevertheless, there is a need to formulate a uniform dose and procedure to achieve homogeneity and develop references for clinical practices. PMID: 31977258 [PubMed - as supplied by publisher]
