Meningitis
Meningitis is an inflammation of the protective membranes covering the brain and spinal cord. It can be caused by bacteria, viruses, fungi, or certain drugs. Common symptoms include fever, headache, and neck stiffness. Diagnosis involves examining cerebrospinal fluid obtained via lumbar puncture. Treatment involves immediate antibiotics, steroids, and other drugs depending on the cause. Complications can include brain damage, hearing loss, and death if not treated promptly.
Bacterial Meningitis
Bacterial meningitis is a common central nervous system infection caused by various bacteria. Neisseria meningitidis is a major cause and produces an endotoxin responsible for circulatory collapse. It occurs sporadically or in epidemics, is transmitted via droplets, and prevalence is higher in young children and spleenectomized patients. Clinical presentation includes headache, fever, vomiting, and neck stiffness. Investigations include CSF analysis and blood cultures. Treatment involves antibiotics and supportive care while complications can include neurological deficits if left untreated. Vaccination and chemoprophylaxis can help prevent further spread.
Complications of meningitis in children
Complications from meningitis can arise from the spread of infection or the healing process. Infection can spread to areas like the brain ventricles, subdural spaces, veins and sinuses, and bloodstream, potentially causing issues like ependymitis, thrombophlebitis, and metastatic infections. During healing, complications include arachnoid fibrosis which can lead to hydrocephalus, cranial nerve compression causing palsies, and obliterative endarteritis resulting in brain ischemia or infarcts. While viral meningitis complications are rare, bacterial meningitis poses greater risks like subdural effusion and neurological sequelae such as deafness, blindness, seizures, and mental retardation

Complications of csom Dr.sithanandha Kumar,29.02.2016
Complications of chronic suppurative otitis media (CSOM) can include both intracranial and extracranial complications. Intracranial complications include meningitis, lateral sinus thrombosis, brain abscess, otitic hydrocephalus, and extradural/subdural abscesses. Extracranial complications involve spread of infection to nearby structures like the mastoid bone, petrous bone, facial nerve, and labyrinth. Prompt diagnosis and treatment of complications is important to prevent morbidity.

2. Meningitis diseses of the brain membrane.pptx
The meninges, which cover the brain and spinal cord, become inflamed in meningitis. Bacterial meningitis is more severe and can cause death or brain damage if untreated. Viral meningitis is usually mild and self-limiting. A lumbar puncture collects cerebrospinal fluid which can be analyzed to distinguish between bacterial and viral meningitis and identify the specific cause. Common symptoms include headache, fever, and neck stiffness, while signs include Kernig's sign and Brudzinski's sign.

1 Meningitis in children.ppt 44$.ppt
This document provides an overview of bacterial meningitis beyond the neonatal period. It defines meningitis as inflammation of the leptomeninges surrounding the brain and spinal cord. The most common causes of meningitis in this age group are Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae type b. Risk factors include young age, recent contact with an infected individual, crowding, and conditions causing impaired immunity. Clinical manifestations may include fever, headache, vomiting, altered mental status, and neck stiffness. Diagnosis involves lumbar puncture and analysis of CSF for pleocytosis, elevated proteins, and low glucose. Management includes supportive care, antibiotics, and corticosteroids

The most common causative organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Clinical features may include fever, headache, vomiting, and signs of meningeal irritation. Diagnosis involves lumbar puncture and culture of CSF. Empiric antibiotic treatment is initiated while awaiting culture results. Complications can be early like seizures or late like hearing loss. Prognosis depends on causative organism, age of presentation, and presence of co-morbidities.
Meningitis
This document discusses meningitis, including its classification, causative organisms, incidence, risk factors, pathophysiology, clinical features, diagnosis, treatment, prevention, and nursing management. It defines meningitis as an inflammation of the membranes surrounding the brain and spinal cord, most commonly caused by bacteria or viruses. The main types are acute bacterial meningitis, which requires emergency treatment, and chronic meningitis, present for over a month. Common causative organisms are pneumococcal, meningococcal, and H. influenza bacteria. Clinical features include headache, fever, neck stiffness, and altered mental status. Diagnosis involves examination of cerebrospinal fluid. Treatment involves antibiotics and supportive care. Nursing focuses on
Meningitis.pptx
The three membranes covering the brain and spinal cord are the dura mater, arachnoid mater, and pia mater. Meningitis is inflammation of these meninges and is most commonly caused by acute bacterial meningitis from Streptococcus pneumoniae, Neisseria meningitidis, or Haemophilus influenzae type B. These bacteria enter the cerebrospinal fluid and cause an inflammatory response, potentially leading to complications like cerebral infarction, increased intracranial pressure, and hydrocephalus. Clinical manifestations of meningitis include nonspecific symptoms like fever and headache as well as signs of meningeal irritation like nuchal rigidity.
Meningitis
Meningitis is an inflammation of the meninges that covers the brain and spinal cord. It is usually caused by viral or bacterial infections, though fungi, drugs, and cancer can also cause meningitis. Symptoms include fever, headache, nausea, and neck stiffness. Diagnosis involves spinal fluid analysis, imaging, and culture tests. Treatment focuses on antibiotics, antivirals, or antifungals depending on cause, with supportive care like IV fluids and fever control. Complications can be serious if untreated and include long term neurological deficits.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
