Definition;

Meningitis is an inflammation of the membranes (meninges) surrounding your brain and spinal cord.
It’s easy to mistake the early signs and symptoms of meningitis for the flu (influenza). Meningitis signs and symptoms may develop over several hours or over one or two days.
Signs and Symptoms;
The signs and symptoms that may occur in anyone older than age of 2 include:
• Sudden high fever
• Severe headache that isn't easily confused with other types of headache
• Stiff neck
• Vomiting or nausea with headache
• Confusion or difficulty concentrating
• Seizures
• Sleepiness or difficulty waking up
• Sensitivity to light
• Lack of interest in drinking and eating
• Skin rash in some cases, such as in meningococcal meningitis
Signs and symptoms in Newborns;
Newborns and infants may not have the classic signs and symptoms of headache and stiff neck. Instead, signs of meningitis in this age group may include:
• High fever
• Constant crying
• Excessive sleepiness or irritability
• Inactivity or sluggishness
• Poor feeding
• A bulge in the soft spot on top of a baby's head (fontanel)
• Stiffness in a baby's body and neck
Infants with meningitis may be difficult to comfort, and may even cry harder when picked up.
Causes;
Meningitis usually results from a viral infection, but the cause may also be a bacterial infection. Less commonly, a fungal infection may cause meningitis. Because bacterial infections are the most serious and can be life-threatening, identifying the source of the infection is an important part of developing a treatment plan.
Bacterial meningitis
Acute bacterial meningitis usually occurs when bacteria enter the bloodstream and migrate to the brain and spinal cord. But it can also occur when bacteria directly invade the meninges, as a result of an ear or sinus infection, or a skull fracture, or rarely, after some…...

...Meningitis BACTERIAL MENINGITIS April 18, 2012 What is meningitis? Meningitis is inflammation of the protective membranes covering the brain and spinal cord, known collectively as MENINGES. People sometimes refer to it as spinal meningitis. Etiology Meningitis is usually caused by a viral or bacterial infection. Knowing whether meningitis is caused by a virus or bacterium is important because the severity of illness and the treatment differ. “In the United States, about 4,100 cases of bacterial meningitis, including 500 deaths, occurred each year between 2003–2007”. (Thigpen MC, Whitney CG, Messonnier NE, Zell ER, Lynfield R, Hadler JL, 2011). Meningitis can be caused by a variety of organism, but bacterial meningitis is caused by three bacteria with complex code names: 1. Haemophilus influenzae type b, (Hib) 2. Pneumococcus (noo-muh-KAHK-us) 3. Meningococcus (meh-NIN-juh-KAHK-us) Hib goes for the 2 month olds to 3 year olds. Pneumococcus hits infants, toddlers, and elderly people hardest. Meningococcus targets children younger than 1 year old. Cause Before the 1990s, Haemophilus influenzae type b (Hib) was the leading cause of bacterial meningitis, but new vaccines being given to all children as part of their routine immunizations have reduced the occurrence of invasive disease due to Haemophilus influenzae. (www.cdc.gov, 2010) Hib meningitis can cause: pneumonia, and throat swelling, and can literally infect the blood, bones, joints, and......

Fungal Meningitis

...Fungal Meningitis During the past several months officials and staff at a Michigan hospital have found themselves at the epicenter of spiraling fungal meningitis outbreak that has turned the facility into a learning laboratory and tested it emergency preparedness. They scramble to manage a virulent infection that has not been seen in humans. In a recent article “Anatomy of an outbreak” written in Modern Healthcare, St Joseph Mercy Ann Arbor hospital has found itself at the center of a national outbreak of fungal meningitis that has so far infected 469 patients in 19 states, killing 33, according to the most recent federal data. The infections have been traced to contaminated lots of injectable steroids, distributed by the Farmingham, Mass.-based New England Compounding Center. St Joseph has treated 123 patients with the disease 73 of whom are hospitalized and 5 that have died. About 620 patients received a total of 750 contaminated steroid injections these patients received injections at Michigan Pain Specialists in Brighton, Michigan. (McKinney, 2012). To ensure treatments that were deemed effective, Trinity Health, St Joseph’s parent health system has set up order sets for the health systems electronic records that correspond with St Joseph’s clinicians and the Centers for Disease Control and Prevention (CDC). Trinity officials spoke with Rep. John Dingell (D-Michigan) who attended the congressional hearing to provide information and the impending shortage of......

Neisseria Meningitidis

...Neisseria Meningitidis Neisseria Meningitidis is a bacteria that is best known for its role in endemic bacterial meningitis (Bingen, 2008). N. Meningitidis is described as gram negative diplococci. Neisseria Meningitidis is non-motile and is transferred among people via direct contact with bodily fluids in which the bacteria has inhabited (Bingen, 2008). N. Meningitidis is classified among the prokaryotes and is a member of the kingdom bacteria because it is unicellular and small as most bacteria (Bingen, 2008). N. Meningitidis can be detected by doing a spinal tap to extract some cerebrospinal fluid from an individual’s spine (Bingen, 2008). If the spinal fluid appears to be cloudy it is most likely infected with bacterial meningitis and is cloudy because it has been placed under increased pressure (Bingen, 2008). The white blood cell count and protein concentration of the CSF will also be elevated if Neisseria Meningitidis is present (Bingen, 2008). N. Meningitidis resides in the nose and throat of humans (Bingen, 2008). It can be found in about 2-8% of humans that are carriers of the bacteria in a normal setting (Bingen, 2008). The bacteria are found in much higher percentages in areas where many people are living together (Bingen, 2008). N. Meningitidis cannot grow in temperatures below 30 degrees Celsius. These bacteria can only grow where fatty acids and trace metals are also present. The nose and throat of humans is perfect because of the warm......

Bacterial Meningitis

...Bacterial Meningitis Meningitis is a bacterial infection of the membranes covering the brain and spinal cord (meninges). Meningitis can be acute, with a quick onset of symptoms, it can be chronic, and lasting a month or more, or it can be mild or aseptic. Acute bacterial meningitis is the most common form of meningitis.Meningitis is a disease that can be passed from person to person (contagious). It is caused most often by viruses or bacteria that infect the tissues, meninges and sometimes the fluid (cerebral spinal fluid, or CSF) that surround the brain and spinal cord. Organisms that cause meningitis can be passed from one person to another or passed from rodents and insects to people. But exposure to an organism that causes meningitis does not mean you will get the infection. During birth, a mother can pass organisms that cause meningitis to her baby even if the mother does not have symptoms. Delivering a baby by cesarean section rather than through the birth canal does not always protect the baby from getting the infection. Both bacteria and viruses can be transmitted this way. Through stool, stool could have enteroviruses or certain types of bacteria in it. Washing hands on a regular basis can help prevent you and your children from getting infected this way. More children than adults get meningitis this way. Through coughing and sneezing. Infected people can pass certain bacteria that are normally found in saliva or mucus in their noses and throats. Through......

Journal Article

...Journal Article Critique According to Bamberger, D. (2010)," bacterial meningitis in the United States remains a medical emergency with a prospective for high morbidity and death even though the annual incidences are declining. With the increased use of conjugate vaccines, the yearly occurrence of bacterial meningitis in the United States dropped from 1.9 to 1.5 cases per 100,000 people between 1998 and 2003, with overall death rate of 15.6%". The age, immunosuppression and neurosurgical procedures add to the like hood of infection from specific pathogens. In people with community-acquired meningitis, aseptic meningitis is a lot more frequent than bacterial meningitis. At least 96% of children with cerebrospinal fluid exocytosis have aseptic meningitis. In adults, the incidence of aseptic meningitis is 7.6 cases per 1000,000 people and most common etiologies are enterovirus, HSV, and varicella-zooster virus infections (Bamberger, 2010). According to Bamberger, D. (2010), "in adults with community-acquires bacterial meningitis, 25% have recent otitis or sinusitis, 12% have pneumonia, and 16 % are immunocompromised". Fever, neck stiffness and altered mental statues are present in 99% to 100% of patients with meningitis. Of the patients that have meningococcal meningitis 63 % of them have a rash that is petechial. Pneumococcal meningitis is more likely than meningococcal meningitis to be associated with seizures, focal neurologic findings, and altered......

Bacterial Meningitis

...INTRODUCTION Bacterial meningitis is characterized by inflammation of the meninges, the membranes lining the brain and spinal cord. In a recent survey by the Hib and Pneumococcal Working Group, the incidence of meningitis in 2000 varied from regions across the world. The overall incidence of pneumococcal meningitis was 17 cases per 100,000, with the highest incidence in Africa at 38 cases per 100,000 and the lowest incidence in Europe at 6 cases per 100,000. The overall death rate was 10 cases per 100,000. The highest death rate was 28 cases per 100,000 in Africa, and the lowest death rates were 3 cases per 100,000 in Europe and Western Pacific regions. (Hom, 2009) Bacterial meningitis more frequently occurs in black and Hispanic children. This is thought to be related to socioeconomic rather than racial factors The brain and spinal cord are remarkably resistant to infection, but when they become infected, the consequences are usually very serious. Infections may be caused by bacteria, viruses, fungi, and occasionally protozoa or parasites. The most common type of CNS infection is Bacterial Meningitis which is characterized by inflammation of the meninges, the membranes lining the brain and spinal cord. (Hom, 2009. Almost any bacteria entering the body can cause meningitis. The most common are meningococci (Neisseria meningitidis), pneumococci (Streptococcus pneumonia), and Haemophilus influenza. Thtese organisms are often present in the nasopharynx. S. pneumonia and N....

He has had a fever for a couple of days, which increased to 102 degrees today. Since yesterday, he’s been complaining of a headache and stiff neck. His mother said last week he had gone swimming in the pond by their barn and started feeling ill a few days later. Fax results ASAP. Best, Terrie Raychee, M.D. Answer the following questions in your own words. 1. What could have caused Jimmy’s disease? When acute inflammation of the first two meninges that cover the brain and spinal cord occurs, a person usually has some form of meningitis. The symptoms of this disease are high fever, a bad headache, stiff neck, nausea, and vomiting. Since Jimmy’s mother said he had been swimming in the pond by their barn and started feeling sick a few days later with symptoms of a high fever, headache, and a stiff neck, he most likely contracted bacterial or viral meningitis. Meningitis, caused by bacteria, fungi, or virus could be how he contracted the disease if bitten by mosquitoes infected with the meningitis and who carry the disease. 2.

...F fever, lethargy, headache, and stiff neck. These are all of the common signs of meningitis. Meningitis is often mistaken for the flu, which could cause further complications with the infection. There are three different types of meningitis: bacterial, viral, chronic, and fungal. Bacterial meningitis can be cause by a strain of bacteria entering the bloodstream and traveling to the spinal cord or meninges of the brain. Also bacterial meningitis can result from ear or sinus infection and/or skull fractures. Rarely this type of meningitis can be caused by infection preceding a surgical procedure. The most common types of bacterial strains include: Streptococcus pneumoniae, Neisseria meningitides, Haemophilus influenzae, and Listeria monocytogenes. Viral meningitis is usually last a short period of time and can disappear on its own. The virus that is usually spread in this instance in the US is enteroviruses. Chronic meningitis is caused by slow-growing organisms intrude into the area around the brain including the fluid and membranes. Lastly, fungal meningitis is the least common form of meningitis and is usually caused by a strain of fungus called Cryptococcal meningitis. This form of meningitis cannot be transferred from person to person but usually is associated with patients that have weak immune systems. Just from the signs and symptoms it would be hard to pinpoint which of type of meningitis the patient has. Other laboratory findings that need to be collected to ensure......

Meningitis and How It Affects the Body.

...At the age of two months old my brother was diagnosed with meningitis in the year of 1978. He had a fever of 104.0 and was taken to St.Christopher’s hospital but then after a few hours was released by staff, stating there was nothing more that they could do. My mother then took him to CHOP Children’s Hospital Of Philadelphia where they immediately started running test on him. The results were in. the doctor’s had concluded that he had a rare case of meningitis, and would need to stay in the hospital for a while before they could find a cure or treatment. In the mean time the staff did everything they could to break the fever, and once it was broken they realized something. My brother wasn’t making any sounds or noises even when they called his name. The social worker came into the room, and spoke to my mother regarding our experience at St.Christopher’s hospital.She was told to speak to a lawyer at once to take legal action for the safety of her child. My mom was grateful to the staff and she thanked them for saving my brothers life. The Er nurses and doctors explained to us that he would have died if he hadn’t come to the Er the time that he did. This is a very serious condition and at this time very less about it was known. Several weeks later the fever finally dropped and stabilized but his hearing was lost. This was such a big transition for us to adjust to but, without knowing how we were going to......

Journal Article Critique: Meningitis

...prevention of meningitis. It discusses the different and most effective ways to diagnose meningitis, such as lumbar puncture, blood cultures, computed tomography, and electronic resonance imaging. Evaluation of the cerebrospinal fluid is the key element in diagnosing meningitis. This article also points out that it is important to start therapies as soon as possible while waiting for the scan results, blood cultures, and lumbar puncture. It is suggested to start antimicrobial therapy or concomitant dexamethasone based on the patient’s history and physical exam, and what type of meningitis is suspected. It is extremely important to determine whether the meningitis is bacterial or aseptic, because bacterial meningitis is life threatening. The mortality rate in adults with bacterial meningitis in developed countries is 21 percent, and in children it is 3 percent. (Bamberger, 2010) In this article we are given a rundown of the common symptoms of bacterial meningitis such as fever, neck stiffness, nausea, headache, altered mental status, seizure, and papilledema. It also states that there are conjugate vaccines available to help with prevention of bacterial meningitis. These include meningococcal, pneumococcal, and H. influenzae vaccines. This article was educational for me because it gives you information that is important to know about meningitis that most people may not know. I now know what signs to look for in my children if they were to ever contract meningitis. The......

...Meningococcal disease, also known as meningitis, is caused by the bacteria known as Neiserria meningitids, and is one of the leading causes of bacterial meningitis worldwide. Outbreaks of this disease are rare in the United States but are very common along an area of sub –Saharan African called the African Belt. The African Belt stretches from the Senegal in the west to Ethiopia in the east with 26 countries involved where it contains the highest rates of the disease. (Who, 2015). Neiserria meningitids is carried in the throat and is transmitted from person to person through droplets of respiratory or throat secretions from carriers. It is secreted from prolonged kissing, sneezing or coughing on someone or by living in close quarters. There is an incubation period of about 4 days before symptoms start to occur. Symptoms of meningitis include a stiff neck, high fever, confusion, headaches vomiting, and sensitivity to light. Meningococcal disease can be a potentially fatal disease if not treated right away. Patients must have a lumbar puncture performed so that spinal fluid can be examined and antibiotics, such as penicillin and ceftriaxone must be given as soon as possible. Sometimes the infection can be severe enough that death or serious long term problems can occur. About 11 to 19 out of every 100 survivors will have long term disabilities such as loss of limb, deafness nervous system problems or brain damage. (CDC, 2015). Meningococcal......

Meningitis & Pneumonitis; Cases Presentation

...you can take steps to prevent it from occurring again. Meningitis Meningitis is a disease involving inflammation of the meninges, the protective layers covering the brain and spinal column. Meningitis may develop in response to a number of causes, usually secondary to infection caused by bacteria, viruses and other pathogens, but also physical injury, cancer or certain drugs. While some forms of meningitis are mild and resolve on their own, meningitis is a potentially life-threatening condition due to the proximity of the inflammation to the brain and spinal cord. The potential for serious neurological damage or even death necessitates prompt medical attention and evaluation. It is very important to know the causes of infection, since treatment and severity of the disease differ for viral, bacterial and fungal meningitis. Viral meningitis is less severe, as compared to bacterial meningitis, and can be resolved “…without a specific treatment.” Bacterial meningitis may be severe and lead to brain damage, hearing loss or learning disability. To prevent the spreading of bacterial meningitis, it is very important to know the strains of bacteria causing meningitis. Types of Meningitis Most cases of meningitis are viral meningitis and bacterial meningitis. Viral meningitis is usually relatively mild. It clears up in a week or two without specific treatment. Viral meningitis is also called aseptic meningitis. It is caused by such viruses as enteroviruses, which......
