Presentation2.pptx intra cranial cyst
Arachnoid cysts are benign lesions that occur in the central nervous system, most often in the intracranial compartment. They are usually located in the subarachnoid space and contain cerebrospinal fluid. Most arachnoid cysts are located in the middle cranial fossa. Brain involvement with hydatid disease occurs in 1-2% of all Echinococcus granulosus infections and usually presents as an intracranial space occupying lesion, more commonly in children. Surgery is the primary treatment option for hydatid cysts of the brain with low mortality and morbidity. The document discusses several other types of cysts that can occur in the brain.
Myelination disorders
This document discusses various white matter diseases and disorders that can be seen on MRI. It provides details on the typical imaging appearance and characteristics of several leukodystrophies and other white matter conditions, including metachromatic leukodystrophy, adrenoleukodystrophy, Krabbe disease, vanishing white matter disease, maple syrup urine disease, megaloencephalic leukodystrophy, Pelizaeus-Merzbacher disease, mucopolysaccharidoses, Canavan disease, Alexander disease, Zellweger syndrome, and Leigh disease. Common findings discussed are T1 and T2 signal abnormalities, diffusion restriction, enhancement patterns, and metabolic abnormalities on MR spectroscopy.

Patterns of Enhancement in the Brain
The document discusses patterns of brain enhancement seen on MRI or CT after contrast administration. It describes 6 common patterns: 1) Periventricular enhancement which can be seen in conditions like lymphoma, infections, or multiple sclerosis. 2) Gyriform enhancement seen in herpes encephalitis, infarcts, or PRES. 3) Nodular subcortical enhancement typically seen in metastatic disease. 4) Ring enhancement commonly from abscesses, metastases, or high grade tumors. 5) Pachymeningeal enhancement of the dura. 6) Leptomeningeal enhancement of the pia-arachnoid membranes. Normal structures that enhance include the choroid plexus, pituitary gland, pineal
DISORDERS OF MYELINATION
This document discusses disorders of myelination. It begins by defining myelin and its functions, describing normal myelination milestones. It then covers various white matter disorders including dysmyelination, hypomyelination, and delayed myelination. Specific leukodystrophies are discussed in more detail such as Canavan's disease, Alexander disease, Van der Knapp disease, and glutaric aciduria type 1. Clinical features, imaging findings, and pathology are described for each condition. The document provides an overview of disorders of myelination.
Imaging in pediatric brain tumors
Pediatric brain tumors account for 20-30% of childhood cancers. Common types include astrocytomas, medulloblastomas, and choroid plexus papillomas. Imaging plays an important role in analyzing potential brain tumors. On CT, tumors may appear as hypodense lesions that enhance with contrast. On MRI, they are often hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging, with variable enhancement. Location, appearance on different sequences, and effects on surrounding structures provide clues to tumor type and diagnosis.

The document discusses the different cell types found in the central nervous system and lists tumors that can arise from these cells. It covers 10 major types of brain tumors, including gliomas arising from neuroglial cells, neuronal tumors, meningiomas from meningeal cells, and metastatic tumors. Key tumor types discussed in more detail include astrocytomas, glioblastoma, medulloblastoma, meningioma, and pilocytic astrocytoma. Grading systems and histopathological features of these tumors are also summarized.
CNS TUMORS.ppt
The document discusses central nervous system (CNS) tumors. It notes that CNS tumors can be primary tumors originating in the brain or spinal cord, or metastatic tumors that have spread from other areas. Primary CNS tumors are more common in children, where 70% arise in the posterior fossa, while in adults most primary tumors arise supratentorially. CNS tumors are classified based on the type of tissue they originate from, with the main types being tumors of glial tissue (gliomas), neurons, and meninges. Gliomas include astrocytomas, oligodendrogliomas, and ependymomas, which are graded based on malignancy characteristics.
Recent updates in cns tumors
This document provides an overview of recent updates to the WHO classification of central nervous system tumors based on the 2016 guidelines. Key points include:
- Incorporation of molecular parameters like IDH, ATRX, and 1p/19q status into tumor classifications to improve diagnostic accuracy.
- Diffuse gliomas are now classified based on shared genetic drivers rather than histology alone. Entities like oligoastrocytoma are discouraged.
- Newly recognized entities include epithelioid glioblastoma and glioblastoma with a primitive neuronal component showing MYC/MYCN amplification.
- The diagnosis of oligodendroglioma now requires both IDH mutation and 1p/
2brain tumors.pptx
Primary brain tumors occur in around 250,000 people globally each year, accounting for less than 2% of all cancers. The most common primary brain tumors are meningiomas (20.8% of cases) and gliomas (50.4% of cases), which originate from glial cells. Gliomas include astrocytomas, oligodendrogliomas, and ependymomas. Astrocytomas are the most common glioma and are graded from I to IV based on factors like cellularity and presence of necrosis, with glioblastoma multiforme being grade IV. Meningiomas originate from the meninges and are typically benign, though some can become malignant. Primary brain tumors are

PRIMARY TUMOUR OF CNS IN ADLUT.pptx
Primary brain tumors are a diverse group of neoplasms that can arise from different cells in the central nervous system. The most common primary brain tumor in adults is brain metastasis. Meningiomas are the most common non-malignant primary brain tumor, followed by pituitary and nerve sheath tumors. Gliomas account for 75% of malignant brain tumors, over half of which are glioblastomas. Primary brain tumors are classified and graded according to the WHO system, with grade I being low proliferative potential and grade IV being most malignant. Clinical features vary depending on tumor location but often include headaches, nausea, seizures, and focal neurological deficits.
PRIMARY TUMOUR OF CNS IN ADULT
Primary brain tumours are a diverse group of neoplasm arising from different cells of the central nervous system.

Efficacy of liquid based cytology versus conventional smears
This study compares the efficacy of liquid-based cytology (LBC) to conventional smear methods for fine needle aspiration cytology samples. The study analyzed 110 cases of various lesions collected over 2 years. Results showed that LBC produced more clear backgrounds and better preserved and dispersed cells compared to conventional smears. LBC allowed for improved diagnosis of lesions like ductal carcinoma, lymph node metastases, and bone lesions. However, LBC required more processing and had some artifacts that could complicate interpretation. Overall, LBC improved sample quality and reduced inadequate sampling compared to conventional smears.

ANA in autoimmunity by DR. ANAMIKA DEV
This document discusses autoantibodies and methods for detecting anti-nuclear antibodies (ANA). ANAs are antibodies directed against nuclear and cytoplasmic antigens and are associated with various autoimmune diseases. The three main methods for detecting ANAs are indirect immunofluorescence assay using HEp-2 cells, ELISA, and multiplex bead immunoassays. The immunofluorescence assay is commonly used for initial screening due to its ability to detect multiple antigen patterns but has limitations. ELISA and bead assays allow detection of specific autoantibodies and have improved sensitivity and specificity compared to immunofluorescence.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.A Classical Text Review on Basavarajeeyam

Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.
